Can lasers be used to measure nerve sensitivity in the skin?
SAN DIEGO – In a 2006 report of complications from laser dermatologic surgery, one of the authors, Dieter Manstein, MD, PhD, who had subjected his forearm to treatment with a fractional laser skin resurfacing prototype device, was included as 1 of the 19 featured cases.
Dr. Manstein, of the Cutaneous Biology Research Center in the department of dermatology at Massachusetts General Hospital, Boston, was exposed to three test spots in the evaluation of the effects of different microscopic thermal zone densities for the prototype device, emitting at 1,450 nm and an energy per MTZ of 3 mJ.
Two years later, hypopigmentation persisted at the test site treated with the highest MTZ density, while two other sites treated with the lower MTZ densities did not show any dyspigmentation. But he noticed something else during the experiment: He felt minimal to no pain as each test site was being treated.
“It took 7 minutes without any cooling or anesthesia,” Dr. Manstein recalled at the annual meeting of the American Society for Laser Medicine and Surgery. “It was not completely painless, but each time the laser was applied, sometimes I felt a little prick, sometimes I felt nothing.” Essentially, he added, “we created cell injury with a focused laser beam without anesthesia,” but this could also indicate that if skin is treated with a fractional laser very slowly, anesthesia is not needed. “Current devices are meant to treat very quickly, but if we [treat] slowly, maybe you could remove lesions painlessly without anesthesia.”
The observation from that experiment also led Dr. Manstein and colleagues to wonder: Could a focused laser beam pattern be used to assess cutaneous innervation? If so, they postulated, perhaps it could be used to not only assess nerve sensitivity of candidates for dermatologic surgery, but as a tool to help diagnose small fiber neuropathies such as diabetic neuropathy, and neuropathies in patients with HIV and sarcoidosis.
The current gold standard for making these diagnoses involves a skin biopsy, immunohistochemical analysis, and nerve fiber quantification, which is not widely available. It also requires strict histologic processing and nerve counting rules. Confocal microscopy of nerve fibers in the cornea is another approach, but is very difficult to perform, “so it would be nice if there was a simple way” to determine nerve fiber density in the skin using a focused laser beam, Dr. Manstein said.
With help from Payal Patel, MD, a dermatology research fellow at MGH, records each subject’s perception of a stimulus, and maps the areas of stimulus response. Current diameters being studied range from 0.076-1.15 mm and depths less than 0.71 mm. “We can focus the laser beam, preset the beam diameter, and very slowly, in a controlled manner, make a rectangular pattern, and after each time, inquire if the subject felt the pulse or not,” Dr. Manstein explained.
“This laser could become a new method for diagnosing nerve fiber neuropathies. If this works well, I think we can miniaturize the device,” he added.
Dr. Manstein disclosed that he is a consultant for Blossom Innovations, R2 Dermatology, and AVAVA. He is also a member of the advisory board for Blossom Innovations.

Sweet Syndrome With Pulmonary Involvement Preceding the Development of Myelodysplastic Syndrome
To the Editor:
A 59-year-old man was referred to our clinic for a rash, fever, and night sweats following treatment for metastatic seminoma with cisplatin and etoposide. Physical examination revealed indurated erythematous papules and plaques on the trunk and upper and lower extremities, some with annular or arcuate configuration with trailing scale (Figure, A). A skin biopsy demonstrated mild papillary dermal edema with a mixed infiltrate of mononuclear cells, neutrophils, eosinophils, mast cells, lymphocytes, and karyorrhectic debris without evidence of leukocytoclastic vasculitis. The histopathologic differential diagnosis included a histiocytoid variant of Sweet syndrome (SS), and our patient’s rapid clinical response to corticosteroids supported this diagnosis.
With a relapsing and remitting course over 3 years, the rash eventually evolved into more edematous papules and plaques (Figure, B), and a repeat biopsy 3 years later was consistent with classic SS. Although the patient's condition improved with prednisone, attempts to taper prednisone invariably resulted in relapse. Multiple steroid-sparing agents were trialed over the course of 3 years including dapsone and mycophenolate mofetil, both of which resulted in hypersensitivity drug eruptions. Colchicine and methotrexate were ineffective. Thalidomide strongly was considered but ultimately was avoided due to substantial existing neuropathy associated with his prior chemotherapy for metastatic seminoma.
Four years after the initial diagnosis of SS, our patient presented with dyspnea and weight loss. Computed tomography revealed a nearly confluent miliary pattern of nodularity in the lungs. A wedge biopsy demonstrated pneumonitis with intra-alveolar fibrin and neutrophils with a notable absence of granulomatous inflammation. Fungal and acid-fast bacilli staining as well as tissue cultures were negative. He had a history of Mycobacterium kansasii pulmonary infection treated 18 months prior; however, in this instance, the histopathology, negative microbial cultures, and rapid steroid responsiveness were consistent with pulmonary involvement of SS. Over the ensuing 2 years, the patient developed worsening of his chronic anemia. He was diagnosed with myelodysplastic syndrome (MDS) by bone marrow biopsy, despite having a normal bone marrow biopsy more than 3 years prior to evaluate his anemia. At this time, thalidomide was initiated at 50 mg daily leading to notable improvement in his SS symptoms; however, he developed worsening neuropathy resulting in the discontinuation of this treatment 2 months later. An investigational combination of vosaroxin and azacytidine was used to treat his MDS, resulting in normalization of blood counts and remission from SS.
Sweet syndrome may occur in the setting of undiagnosed cancer or may signal the return of a previously treated malignancy. The first description of SS associated with solid tumors was in a patient with testicular cancer,1 which prompted continuous surveillance for recurrent seminoma in our patient, though none was found. Hematologic malignancies, as well as MDS, often are associated with SS.2 In our patient, multiple atypical features linked the development of SS to the ultimate presentation of MDS. The initial finding of a histiocytoid variant has been described in a case series of 9 patients with chronic relapsing SS who eventually developed MDS with latency of up to 7 years. The histopathology in these cases evolved over time to that of classic neutrophilic SS.3 Pulmonary involvement of SS is another interesting aspect of our case. In one analysis, 18 of 34 (53%) cases with pulmonary involvement featured hematologic pathology, including myelodysplasia and acute leukemia.4
In our patient, SS preceded the clinical manifestation of MDS by 6 years. A similar phenomenon has been described in a patient with SS that preceded myelodysplasia by 30 months and was recalcitrant to numerous steroid-sparing therapies except thalidomide, despite the persistence of myelodysplasia. Tapering thalidomide, however, resulted in recurrence of SS lesions in that patient.5 In another case, resolution of myelodysplasia from azacytidine treatment was associated with remission from SS.6
Our case represents a confluence of atypical features that seem to define myelodysplasia-associated SS, including the initial presentation with a clinically atypical histiocytoid variant, chronic relapsing and remitting course, and extracutaneous involvement of the lungs. These findings should prompt surveillance for hematologic malignancy or myelodysplasia. Serial bone marrow biopsies were required to evaluate persistent anemia before the histopathologic findings of MDS became apparent in our patient. Thalidomide was an effective treatment for the cutaneous manifestations in our patient and should be considered as a steroid-sparing agent in the treatment of recalcitrant SS. Despite the discontinuation of thalidomide therapy, effective control of our patient’s myelodysplasia with chemotherapy has kept him in remission from SS for more than 7 years of follow-up, suggesting a causal relationship between these disorders.

Practice Points
- Sweet syndrome is characterized by the clinical constellation of fever, a skin eruption of tender erythematous papules or plaques, and response to corticosteroids.
- Skin biopsy characteristically demonstrates marked papillary dermal edema with a dense infiltrate of mature neutrophils without leukocytoclasia.
- Sweet syndrome often is idiopathic, though it has been associated with infection, autoimmunity, medication, and malignancy.
Hospital medicine gains popularity among newly minted physicians
In a new study, published in Annals of Internal Medicine, researchers from ABIM reviewed certification data from 67,902 general internists, accounting for 80% of all general internists certified in the United States from 1990 to 2017.
The researchers also used data from Medicare fee-for-service claims from 2008-2018 to measure and categorize practice setting types. The claims were from patients aged 65 years or older with at least 20 evaluation and management visits each year. Practice settings were categorized as hospitalist, outpatient, or mixed.
“ABIM is always working to understand the real-life experience of physicians, and this project grew out of that sort of analysis,” lead author Bradley M. Gray, PhD, a health services researcher at ABIM in Philadelphia, said in an interview. “We wanted to better understand practice setting, because that relates to the kinds of questions that we ask on our certifying exams. When we did this, we noticed a trend toward hospital medicine.”
Overall, the percentages of general internists in hospitalist practice and outpatient-only practice increased during the study period, from 25% to 40% and from 23% to 38%, respectively. By contrast, the percentage of general internists in a mixed-practice setting decreased from 52% to 23%, a 56% decline. Most of the physicians who left the mixed practice setting switched to outpatient-only practices.
Among the internists certified in 2017, 71% practiced as hospitalists, compared with 8% practicing as outpatient-only physicians. Most physicians remained in their original choice of practice setting. For physicians certified in 1999 and 2012, 86% and 85%, respectively, of those who chose hospitalist medicine remained in the hospital setting 5 years later, as did 95% of outpatient physicians, but only 57% of mixed-practice physicians.
The shift to outpatient practice among senior physicians offset the potential decline in outpatient primary care resulting from the increased choice of hospitalist medicine by new internists, the researchers noted.
The study findings were limited by several factors, including the reliance on Medicare fee-for-service claims, the researchers noted.
“We were surprised by both the dramatic shift toward hospital medicine by new physicians and the shift to outpatient only (an extreme category) for more senior physicians,” Dr. Gray said in an interview.
The shift toward outpatient practice among older physicians may be driven by convenience, said Dr. Gray. “I suspect that it is more efficient to specialize in terms of practice setting. Only seeing patients in the outpatient setting means that you don’t have to travel to the hospital, which can be time consuming.
“Also, with fewer new physicians going into primary care, older physicians need to focus on outpatient visits. This could be problematic in the future as more senior physicians retire and are replaced by new physicians who focus on hospital care,” which could lead to more shortages in primary care physicians, he explained.
The trend toward hospital medicine as a career has been going on since before the pandemic, said Dr. Gray. “I don’t think the pandemic will ultimately impact this trend. That said, at least in the short run, there may have been a decreased demand for primary care, but that is just my speculation. As more data flow in we will be able to answer this question more directly.”
Next steps for research included digging deeper into the data to understand the nature of conditions facing hospitalists, Dr. Gray said.
Implications for primary care
“This study provides an updated snapshot of the popularity of hospital medicine,” said Bradley A. Sharpe, MD, of the division of hospital medicine at the University of California, San Francisco. “It is also important to conduct this study now as health systems think about the challenge of providing high-quality primary care with a rapidly decreasing number of internists choosing to practice outpatient medicine.” Dr. Sharpe was not involved in the study.
“The most surprising finding to me was not the increase in general internists focusing on hospital medicine, but the amount of the increase; it is remarkable that nearly three quarters of general internists are choosing to practice as hospitalists,” Dr. Sharpe noted.
“I think there are a number of key factors at play,” he said. “First, as hospital medicine as a field is now more than 25 years old, hospitals and health systems have evolved to create hospital medicine jobs that are interesting, engaging, rewarding (financially and otherwise), doable, and sustainable. Second, being an outpatient internist is incredibly challenging; multiple studies have shown that it is essentially impossible to complete the evidence-based preventive care for a panel of patients on top of everything else. We know burnout rates are often higher among primary care and family medicine providers. On top of that, the expansion of electronic health records and patient access has led to a massive increase in messages to providers; this has been shown to be associated with burnout.”
The potential impact of the pandemic on physicians’ choices and the trend toward hospital medicine is an interested question, Dr. Sharpe said. The current study showed only trends through 2017.
“To be honest, I think it is difficult to predict,” he said. “Hospitalists shouldered much of the burden of COVID care nationally and burnout rates are high. One could imagine the extra work (as well as concern for personal safety) could lead to fewer providers choosing hospital medicine.
“At the same time, the pandemic has driven many of us to reflect on life and our values and what is important and, through that lens, providers might choose hospital medicine as a more sustainable, do-able, rewarding, and enjoyable career choice,” Dr. Sharpe emphasized.
“Additional research could explore the drivers of this clear trend toward hospital medicine. Determining what is motivating this trend could help hospitals and health systems ensure they have the right workforce for the future and, in particular, how to create outpatient positions that are attractive and rewarding,” he said.
The study received no outside funding. The researchers and Dr. Sharpe disclosed no relevant financial relationships.

Most of the physicians who left the mixed practice setting switched to outpatient-only practices.
Among the internists certified in 2017, 71% practiced as hospitalists, compared with 8% practicing as outpatient-only physicians. Most physicians remained in their original choice of practice setting. For physicians certified in 1999 and 2012, 86% and 85%, respectively, of those who chose hospitalist medicine remained in the hospital setting 5 years later, as did 95% of outpatient physicians, but only 57% of mixed-practice physicians.
The shift to outpatient practice among senior physicians offset the potential decline in outpatient primary care resulting from the increased choice of hospitalist medicine by new internists, the researchers noted.
The study findings were limited by several factors, including the reliance on Medicare fee-for-service claims, the researchers noted.
“We were surprised by both the dramatic shift toward hospital medicine by new physicians and the shift to outpatient only (an extreme category) for more senior physicians,” Dr. Gray said in an interview.
The shift toward outpatient practice among older physicians may be driven by convenience, said Dr. Gray. “I suspect that it is more efficient to specialize in terms of practice setting. Only seeing patients in the outpatient setting means that you don’t have to travel to the hospital, which can be time consuming.
“Also, with fewer new physicians going into primary care, older physicians need to focus on outpatient visits. This could be problematic in the future as more senior physicians retire and are replaced by new physicians who focus on hospital care,” which could lead to more shortages in primary care physicians, he explained.
The trend toward hospital medicine as a career has been going on since before the pandemic, said Dr. Gray. “I don’t think the pandemic will ultimately impact this trend. That said, at least in the short run, there may have been a decreased demand for primary care, but that is just my speculation. As more data flow in we will be able to answer this question more directly.”
Next steps for research included digging deeper into the data to understand the nature of conditions facing hospitalists, Dr. Gray said.
Implications for primary care
“This study provides an updated snapshot of the popularity of hospital medicine,” said Bradley A. Sharpe, MD, of the division of hospital medicine at the University of California, San Francisco. “It is also important to conduct this study now as health systems think about the challenge of providing high-quality primary care with a rapidly decreasing number of internists choosing to practice outpatient medicine.” Dr. Sharpe was not involved in the study.
“The most surprising finding to me was not the increase in general internists focusing on hospital medicine, but the amount of the increase; it is remarkable that nearly three quarters of general internists are choosing to practice as hospitalists,” Dr. Sharpe noted.
“I think there are a number of key factors at play,” he said. “First, as hospital medicine as a field is now more than 25 years old, hospitals and health systems have evolved to create hospital medicine jobs that are interesting, engaging, rewarding (financially and otherwise), doable, and sustainable. Second, being an outpatient internist is incredibly challenging; multiple studies have shown that it is essentially impossible to complete the evidence-based preventive care for a panel of patients on top of everything else. We know burnout rates are often higher among primary care and family medicine providers. On top of that, the expansion of electronic health records and patient access has led to a massive increase in messages to providers; this has been shown to be associated with burnout.”
The potential impact of the pandemic on physicians’ choices and the trend toward hospital medicine is an interested question, Dr. Sharpe said. The current study showed only trends through 2017.
“To be honest, I think it is difficult to predict,” he said. “Hospitalists shouldered much of the burden of COVID care nationally and burnout rates are high. One could imagine the extra work (as well as concern for personal safety) could lead to fewer providers choosing hospital medicine.
“At the same time, the pandemic has driven many of us to reflect on life and our values and what is important and, through that lens, providers might choose hospital medicine as a more sustainable, do-able, rewarding, and enjoyable career choice,” Dr. Sharpe emphasized.
“Additional research could explore the drivers of this clear trend toward hospital medicine. Determining what is motivating this trend could help hospitals and health systems ensure they have the right workforce for the future and, in particular, how to create outpatient positions that are attractive and rewarding,” he said.
The study received no outside funding. The researchers and Dr. Sharpe disclosed no relevant financial relationships.

In a new study, published in Annals of Internal Medicine, researchers from ABIM reviewed certification data from 67,902 general internists, accounting for 80% of all general internists certified in the United States from 1990 to 2017.
The researchers also used data from Medicare fee-for-service claims from 2008-2018 to measure and categorize practice setting types. The claims were from patients aged 65 years or older with at least 20 evaluation and management visits each year. Practice settings were categorized as hospitalist, outpatient, or mixed.
“ABIM is always working to understand the real-life experience of physicians, and this project grew out of that sort of analysis,” lead author Bradley M. Gray, PhD, a health services researcher at ABIM in Philadelphia, said in an interview. “We wanted to better understand practice setting, because that relates to the kinds of questions that we ask on our certifying exams. When we did this, we noticed a trend toward hospital medicine.”

Calcified Urachal Remnant in a Young Adult: An Unusual Case
To the Editor:
An otherwise healthy 26-year-old man presented to our outpatient clinic with a 15- to 20-mm, shiny, friable-appearing, red umbilical nodule with clear malodorous discharge (Figure 1). The lesion developed 2 weeks prior and gradually increased in size and discomfort. The patient reported mild associated abdominal pain. He had no fever, changes in urination or bowel movements, or prior history of umbilical growths or drainage. The abdomen was tender to palpation.
Differential diagnoses included pyogenic granuloma, umbilical hernia, epidermoid cyst or abscess, and malignancy (low suspicion). A biopsy was not performed due to concern for bleeding or communication with the bowel. A complete blood cell count, comprehensive metabolic panel, and urinalysis were unremarkable except for mild leukocytosis and elevated C-reactive protein. Ultrasonography revealed a 1.4×1.3-cm inflammatory umbilical mass with no communication with the bowel. The patient was referred to the emergency department (ED) for further evaluation. Computed tomography (CT) revealed periumbilical inflammation and an associated 1-cm calcification that appeared to be connected to a potential tract from the bladder, suggestive of a urachal remnant calcification (Figure 2). The patient was diagnosed with a persistent urachal remnant, discharged home with ciprofloxacin, and scheduled for a follow-up with urology.
The patient returned to the ED 3 days later with painful umbilical bleeding (Figure 3). While there, the patient extracted a 1-cm stone from the lesion, consistent with the calcification visualized on CT scan. Computed tomographic virtual cystoscopy showed no connection between the bladder and umbilicus. He was diagnosed with an umbilical-urachal sinus. Complete surgical excision was recommended and performed by urology without complication.
We report an unusual presentation of a symptomatic urachal remnant in an adult. During embryogenesis, the urachus connects the umbilicus to the developing bladder and normally involutes during development. Incomplete regression can cause rare pathological urachal anomalies. The clinical presentation is nonspecific and differs between children and adults, with most cases presenting during infancy or childhood.1 Pediatric urachal abnormalities often present with umbilical drainage, abdominal pain, a palpable mass, an abnormal appearance of the umbilicus, or urinary tract infections.2,3 In adults, the most common symptoms include hematuria, pain, or dysuria. Alternatively, they may be asympomatic3 or present with periumbilical dermatitis4 or abscess. Rodrigues and Gandhi5 reported another case of a symptomatic calculus formed within a urachal remnant. Calcifications in urachal remnants are rare and usually are reported as incidental radiologic findings.
Overall, visible umbilical masses occur infrequently. In addition to urachal anomalies, the differential diagnosis includes several benign and malignant pathologies. Benign causes include epidermoid cysts, foreign body granulomas, pyogenic granulomas, abscesses, hamartomas, nevi, hemangiomas, dermatofibromas, neurofibromas, lipomas, granular cell tumors, desmoid tumors, keloid scars, omphaliths, hernias, or omphalomesenteric duct remnants.6 Primary malignancies (eg, skin cancers, urachal adenocarcinoma, mesenchymal tumors) or metastasis (ie, Sister Mary Joseph nodule) also can present as umbilical nodules.
The wide range of clinical presentations of urachal anomalies combined with the rarity make diagnosis difficult. Thus, it is essential to have a high index of suspicion and awareness of how they can present. Ultrasonography and CT scan are useful tools in making the diagnosis. Urachal anomalies are prone to infection or can be associated with malignancy; therefore, timely and correct diagnosis is critical. Although surgical removal is the primary treatment for urachal anomalies, it may not be the primary treatment of the other entities included in the differential diagnosis of umbilical nodules. For example, the Sister Mary Joseph nodule can be associated with various primary malignancies, which should be treated accordingly.

Practice Points
- Visible umbilical nodules occur infrequently; the differential diagnosis is broad and consists of various benign and malignant pathologies.
- Disruption of the involution of the urachus during development can lead to various rare anomalies.
- Urachal anomalies are important to diagnose given the potential for secondary infection or malignancy.
Today’s medical oxymoron: Healthy overconfidence
Doctor, doctor, gimme the news. I got a bad case of knowing better than you
Stop us if you’ve heard this before. One of your parents (let’s be honest, probably your ornery father) refuses to go to the doctor. You tell him it’s for the best, but in his words, “Doctors don’t know nothin’. I’m fine.” How many TV shows with grumpy fathers feature this exact plot in an episode as the frustrated child attempts increasingly convoluted traps to encourage the stubborn parent to get himself to the doctor?
As is so often the case, wacky sitcoms reflect reality, according to a new study from the Journal of the Economics of Aging. In a massive survey of 80,000 Europeans aged 50 years and older, the researchers found that individuals who were overconfident and rated their health as better than it actually was visited their doctor 17% less often than did those who correctly judge their own health. Fewer medical visits leaves them more vulnerable to chronic disease, since they’re not getting the preventive care they need to catch illnesses early.
Perhaps unsurprisingly, the inverse is also true: People who underestimate their health status visit the doctor 21% more often. On the one hand, regular visits to the doctor are a good thing, as is awareness of how healthy one really is. On the other hand, though, extra visits cost money and time, especially relevant in an aging society with high public health costs.
Nobody likes visiting the doctor, but it is kind of important, especially as we age and our bodies start to let us down. Confidence is fine, but don’t be overly confident. And if you do go, don’t be like a certain former president of the United States. Don’t pay a sycophant to look in your general direction and then declare that you are in very good (great!) condition on Twitter. That’s not how medicine is meant to work.
Your liver stays toddler age
Rapid cell regeneration might seem like something straight out of a sci-fi novel, but it happens to your liver all the time. So much so that the human liver is never a day over 3 years old.
How’s that possible? The liver deals with a lot of toxic substances in its job as the Brita filter of the human body, so it has a unique capacity among organs to regenerate itself after damage.
Dr. Olaf Bergmann and his team at Technical University Dresden’s (Germany) Center for Regenerative Therapies used retrospective radiocarbon birth dating to determine the age of the livers of a group of people who died at the ages of 20-84 years. The results were the same regardless of age.
This information could be a complete game changer for understanding cell regeneration. It’s important in determining cancer cell formation in the liver but also if new heart muscle cells can be generated in people with cardiovascular disease, which the researchers are looking into.
So sure, your liver may be totally capable of filtering those drinks at happy hour, but as old as it is, a juice box might be more appropriate.
To bee, or not to bee? That is the vacation
Sleeping is pretty important for humans, no doubt about that, so anything that improves sleep is worth considering, right? But how far would you go for a good night’s sleep? Would you be willing to travel to Italy to experience the ultimate white-noise generator?
For more on this exciting, yet also sleep-inducing, news story, let’s go to the village of Grottole in southern Italy, where we meet bee keeper and Airbnb host Rocco Filomeno. ”This is the first place in the world where you can sleep immersed in the distinctive sound and aroma of the bees, experiencing ‘bee-therapy’ in the most authentic and natural way,” he said in a written statement for Airbnb.
Mr. Filomeno worked with local NGO Wonder Grottole and a self-build specialist to take the next step in tiny-house evolution. The resulting structure cost just $17,000 – crowdfunded, of course, and built by 25 local bee-lievers (aka volunteers) – and consists of a single room surrounded by nine apiaries, which contain a combined total of 1 million working bees. It is now available to book on Airbnb, and guests “will receive their first lesson on bees and how to live with them,” Airbnb said.
The immersion in bee sound/scent is fully realized through the building’s most prominent interior feature, a screened box in the ceiling with a working hive that allows guests to see the bees and fall asleep to the “gently humming sound,” Airbnb explained. The sound from the hive is said to have a soothing effect that “acts as salve to day-to-day stressors,” according to the BBC.
This is just the start of a trend and we want in on it. Should our tiny house feature the sights/smells/sounds of angry rattlesnakes or a swarm of locusts?
Joysticks can make the world a better place
Someday, it might be possible for surgeons to treat a stroke or aneurysm during the “golden hour,” even if they’re not in the same hospital as the patient. MIT engineers have created a robotic system that can be controlled remotely with a modified joystick, so the patient can go to a closer, smaller hospital and be treated by a surgeon at a larger facility through live imaging.
Endovascular surgery seems difficult enough with the patient and doctor in the same hospital, “but having a robot twist with the same level of sophistication [as a surgeon] is challenging,” Yoonho Kim, lead author of a study in Science Robotics, said in a written statement. “Our system is based on a fundamentally different mechanism.”
It involves “a medical-grade robotic arm with a magnet attached to its wrist. With a joystick and live imaging, an operator can adjust the magnet’s orientation and manipulate the arm to guide a soft and thin magnetic wire through arteries and vessels,” MIT explained in the statement.
The system was tested using life-like models, and it took each surgeon about an hour of training to learn how to use the new joystick and other equipment. Another perk: No exposure to radiation from x-ray imaging.
If someone you know is obsessed with video games, stop thinking “slacker” and start thinking “neurosurgeon.”

Sleeping is pretty important for humans, no doubt about that, so anything that improves sleep is worth considering, right? But how far would you go for a good night’s sleep? Would you be willing to travel to Italy to experience the ultimate white-noise generator?
For more on this exciting, yet also sleep-inducing, news story, let’s go to the village of Grottole in southern Italy, where we meet bee keeper and Airbnb host Rocco Filomeno. ”This is the first place in the world where you can sleep immersed in the distinctive sound and aroma of the bees, experiencing ‘bee-therapy’ in the most authentic and natural way,” he said in a written statement for Airbnb.
Mr. Filomeno worked with local NGO Wonder Grottole and a self-build specialist to take the next step in tiny-house evolution. The resulting structure cost just $17,000 – crowdfunded, of course, and built by 25 local bee-lievers (aka volunteers) – and consists of a single room surrounded by nine apiaries, which contain a combined total of 1 million working bees. It is now available to book on Airbnb, and guests “will receive their first lesson on bees and how to live with them,” Airbnb said.
The immersion in bee sound/scent is fully realized through the building’s most prominent interior feature, a screened box in the ceiling with a working hive that allows guests to see the bees and fall asleep to the “gently humming sound,” Airbnb explained. The sound from the hive is said to have a soothing effect that “acts as salve to day-to-day stressors,” according to the BBC.
This is just the start of a trend and we want in on it. Should our tiny house feature the sights/smells/sounds of angry rattlesnakes or a swarm of locusts?
Joysticks can make the world a better place
Someday, it might be possible for surgeons to treat a stroke or aneurysm during the “golden hour,” even if they’re not in the same hospital as the patient. MIT engineers have created a robotic system that can be controlled remotely with a modified joystick, so the patient can go to a closer, smaller hospital and be treated by a surgeon at a larger facility through live imaging.
Endovascular surgery seems difficult enough with the patient and doctor in the same hospital, “but having a robot twist with the same level of sophistication [as a surgeon] is challenging,” Yoonho Kim, lead author of a study in Science Robotics, said in a written statement. “Our system is based on a fundamentally different mechanism.”
It involves “a medical-grade robotic arm with a magnet attached to its wrist. With a joystick and live imaging, an operator can adjust the magnet’s orientation and manipulate the arm to guide a soft and thin magnetic wire through arteries and vessels,” MIT explained in the statement.
The system was tested using life-like models, and it took each surgeon about an hour of training to learn how to use the new joystick and other equipment. Another perk: No exposure to radiation from x-ray imaging.
If someone you know is obsessed with video games, stop thinking “slacker” and start thinking “neurosurgeon.”
Doctor, doctor, gimme the news. I got a bad case of knowing better than you
Stop us if you’ve heard this before. One of your parents (let’s be honest, probably your ornery father) refuses to go to the doctor. You tell him it’s for the best, but in his words, “Doctors don’t know nothin’. I’m fine.” How many TV shows with grumpy fathers feature this exact plot in an episode as the frustrated child attempts increasingly convoluted traps to encourage the stubborn parent to get himself to the doctor?
As is so often the case, wacky sitcoms reflect reality, according to a new study from the Journal of the Economics of Aging. In a massive survey of 80,000 Europeans aged 50 years and older, the researchers found that individuals who were overconfident and rated their health as better than it actually was visited their doctor 17% less often than did those who correctly judge their own health. Fewer medical visits leaves them more vulnerable to chronic disease, since they’re not getting the preventive care they need to catch illnesses early.
Perhaps unsurprisingly, the inverse is also true: People who underestimate their health status visit the doctor 21% more often. On the one hand, regular visits to the doctor are a good thing, as is awareness of how healthy one really is. On the other hand, though, extra visits cost money and time, especially relevant in an aging society with high public health costs.
Nobody likes visiting the doctor, but it is kind of important, especially as we age and our bodies start to let us down. Confidence is fine, but don’t be overly confident. And if you do go, don’t be like a certain former president of the United States. Don’t pay a sycophant to look in your general direction and then declare that you are in very good (great!) condition on Twitter. That’s not how medicine is meant to work.
Your liver stays toddler age
Rapid cell regeneration might seem like something straight out of a sci-fi novel, but it happens to your liver all the time. So much so that the human liver is never a day over 3 years old.
How’s that possible? The liver deals with a lot of toxic substances in its job as the Brita filter of the human body, so it has a unique capacity among organs to regenerate itself after damage.
Dr. Olaf Bergmann and his team at Technical University Dresden’s (Germany) Center for Regenerative Therapies used retrospective radiocarbon birth dating to determine the age of the livers of a group of people who died at the ages of 20-84 years. The results were the same regardless of age.
This information could be a complete game changer for understanding cell regeneration. It’s important in determining cancer cell formation in the liver but also if new heart muscle cells can be generated in people with cardiovascular disease, which the researchers are looking into.
So sure, your liver may be totally capable of filtering those drinks at happy hour, but as old as it is, a juice box might be more appropriate.

Question 2
Q2. Correct answer: A. Reassurance and consideration of cow milk protein soy intolerance with elimination of these antigens in mother's diet.
Rationale
The differential diagnosis of hematochezia in infants is relatively small. The most likely considerations are anal fissures, vascular malformations, cow milk protein soy intolerance, bleeding diatheses, swallowed maternal blood in the first 1-2 days of life, and necrotizing enterocolitis in preterm infants. In the setting of an otherwise healthy term infant who presents with hematochezia without anorectal malformations, the most likely etiology is cow milk protein soy intolerance. This is an IgG-mediated disorder that does not necessarily construe other predilections to food allergies. Most infants outgrow this by 1 year of life or thereafter. In mother's who are breastfeeding, it is recommended that they eliminate both cow milk and soymilk proteins from their diet. There is a 70% cross-reactivity between cow milk and soymilk proteins. In infants who are formula feeding or those who do not respond to maternal elimination diets, it is recommended that they consume partially hydrolyzed or fully hydrolyzed formula. Such infants are usually able to tolerate cow and soy proteins later in life.

Q2. A 6-week-old otherwise healthy female term infant presents to the office for evaluation of hematochezia. Her pre- and perinatal course was uncomplicated. Her mother has been breastfeeding her and noted evidence of small streaks of blood in her diaper with some mucus over the last 1-2 weeks. There have been no associated fevers, chills, nausea, vomiting, or abdominal pain. She is otherwise breastfeeding well, and her mother has not introduced any formulas. There is no report of bleeding diatheses. She has no bruising or other abnormalities. Her mother is very concerned.
Question 1
Q1. Correct answer: A. Normal Ph/Impedance probe findings during sleeping.
Rationale
Rumination syndrome is a functional gastrointestinal disorder that can present in all age groups. The true prevalence of the disorder is unknown, but the condition can be seen more commonly in patients with developmental disorders and other high-risk groups like teenage females. The ROME IV criteria for the condition include at least 2 months of the following: Repeated regurgitation and rechewing or expulsion of food that begins soon after eating and stops with sleeping, is not proceeded by retching, and has no other clear etiology for symptoms. This patient is at higher risk for rumination syndrome with her developmental differences. Her painless regurgitation after eating meets criteria for the condition. Prolonged high-resolution esophageal manometry can identify specific subgroups of rumination. Antroduodenal manometry can detect simultaneous contractions called R-waves that can be seen in some patients with rumination syndrome. Since regurgitation stops with sleeping, pH/Impedance probes demonstrate resolution of symptoms with sleep. The condition is primarily diagnosed clinically, with other studies performed as clinically indicated. Treatment typically consists of behavioral management.

Tin in permanent contraception implants causes toxicity
Essure implants arrived on the market in 2002 as permanent contraception for women older than age 45 years with children. They were recalled in 2017. Presented as an alternative to laparoscopic tubal ligation, this medical device resulted in rare side effects affecting thousands of women, most notably the nervous system, cardiovascular system, endocrine system, and musculoskeletal system.
Implant analysis protocol
“My research focuses on a variety of medical devices, mostly joint replacements, and more specifically, hip replacements. I look at how these materials behave in humans and how the wear debris affects the body,” explained Ana Maria Trunfio-Sfarghiu, bioengineering expert and research associate with the French National Center for Scientific Research at the Lyon National Institute of Applied Sciences’ Contact and Structure Mechanics Laboratory.
“The problems with Essure implants started with a woman who had been using one for about 10 years and was experiencing side effects such as trouble concentrating and focusing, significant vaginal bleeding, extreme tiredness, hair loss, etc. She had the implant removed, and we retrieved it from her gynecologist and analyzed it alongside other implants,” said Ms. Trunfio-Sfarghiu.
“Together with the hospital, we set up an implant analysis protocol. We visited hospital teams to demonstrate how to prepare the biopsies, embedded in paraffin blocks, before sending them to us for analysis. We gave the same specimen preparation instructions for all subjects,” Ms. Trunfio-Sfarghiu explained.
After a year of clinical analysis, the Journal of Trace Elements in Medicine and Biology published an article about 18 cases.
Implant weld corrosion
The Essure implant measures a few centimeters long and resembles a small spring. Once it is released inside the fallopian tube, its goal is to create inflammation and block the tube. It triggers fibrosis, which prevents the sperm from reaching the egg. Premarketing tests had shown that the fibrosis surrounding the implant would keep it from moving. However, the pharmaceutical company hadn’t assessed the mechanical integrity of the spring weld, which was made of silver-tin.
During their analysis in collaboration with the Minapath laboratory, Ms. Trunfio-Sfarghiu’s team found that the weld had corroded and that tin particles had been released into the subjects’ bodies. “The study included about 40 women, and we found tin in all of them,” said Ms. Trunfio-Sfarghiu.
This weld corrosion has several possible consequences. “When the implant degrades, it can travel anywhere in the pelvis, like a needle moving through the body with no apparent destination. The surgeons who operate to remove it describe similar surgeries in military medicine when the patient has been hit by a bullet!”
Organotin toxicity
Although tin is not especially toxic for the body when ingested, it can bind to organic compounds if it passes through to the blood. “When tin binds to a carbon atom, it becomes organotin, a neurotoxin,” said Ms. Trunfio-Sfarghiu.
She said that this organotin can travel to the brain and trigger symptoms like those found in patients with Essure implants. “For the time being, there is insufficient data to assert that we found organotin in all subjects. Another more in-depth study would be needed to assess migration to the brain. For the past 2 years, we have tried to obtain academic funding to continue our research, so far without success. Academic and political authorities seem to be a bit scared of what we’ve found,” said Ms. Trunfio-Sfarghiu.
For her, “it’s how the implant was marketed that is problematic. The implant was designed to create local inflammation, inflammation in itself being difficult to control. Some women need to have their entire uterus and ovaries removed to resolve problems caused by the implant.”
Harm in the United States
Ms. Trunfio-Sfarghiu’s research has helped American victims obtain acknowledgment of their suffering in the United States. “But the harm caused to women by defective implants has yet to be acknowledged in France,” she added.
She explained that Essure was recalled in 2017 because sales were poor, not because it was deemed dangerous. Her conclusion? “No implant that creates inflammation should be authorized, especially if there is a surgical alternative, which there is here: tubal ligation.”

From the editor: Celebrating 15 years of excellence
The inaugural issue of GI & Hepatology News was published in January 2007, and the newspaper has gone on to become part of the fabric of the AGA. This year, we celebrate the newspaper’s 15th year with a special 15th Anniversary Series that will run from June through December 2022. We will feature reflections from GIHN’s three former editors-in-chief, Dr. Charles J. Lightdale, Dr. Colin Howden, and Dr. John Allen, on the evolution of the newspaper (and the field of GI) over the past 15 years. We also will present a series of Then and Now columns, highlighting high-impact areas of GI and hepatology covered in past GIHN issues, and reflecting on how the field has changed since that time.
In this month’s issue, we are pleased to kick off the 15th Anniversary Series with reflections by Dr. Lightdale, GIHN’s inaugural editor-in-chief, as well as a Then and Now column written by Dr. Kimberly M. Persley (GIHN associate editor and longstanding AGA member) reflecting on how the demographics of gastroenterology and of the AGA as an organization have changed over the past 15 years. I hope you will find these special contributions to be engaging and thought-provoking. Other issue highlights include a lead article describing impacts of social determinants of health in driving disparities in IBD care and offering recommendations for achieving IBD health equity, a new AGA Clinical Practice Update on dietary options for our many patients with irritable bowel syndrome, and new data on the safety of anti-TNF medications prior to surgery in patients with inflammatory bowel disease.
As summer vacation season commences, I hope you will join me in taking some well-deserved time away from work demands, spending some quality time with friends and family, and seizing the opportunity to rest and recharge.

Studies address ibrutinib bleeding risk in patients with CLL receiving Mohs surgery
Patients receiving , new research shows.
“Our cohort of CLL patients on ibrutinib had a two-times greater risk of bleeding complications relative to those on anticoagulants and a nearly 40-times greater risk of bleeding complications relative to those patients on no anticoagulants or CLL therapy,” Kelsey E. Hirotsu, MD, first author of one of two studies on the issue presented at the American College of Mohs Surgery annual meeting, told this news organization.
“It was definitely surprising to see this doubled risk with ibrutinib relative to anticoagulants, and certainly highlights the clinically relevant increased bleeding risk in patients on ibrutinib,” said Dr. Hirotsu, a Mohs micrographic surgery fellow in the department of dermatology, University of California, San Diego (UCSD).
With CLL associated with an increased risk for aggressive skin cancers, particularly squamous cell carcinoma, Mohs surgeons may commonly find themselves treating patients with these unique considerations. Surgical treatment of those cancers can be complicated not only because of potential underlying thrombocytopenia, which occurs in about 5% of untreated CLL patients, but also because of the increased risk for bleeding that is associated with the use of the Bruton tyrosine kinase inhibitor ibrutinib, commonly used for CLL.
While the nature of the increased bleeding-related complications among patients with CLL undergoing Mohs surgery has been documented in some case reports, evidence from larger studies has been lacking.
In one of the studies presented at the ACMS meeting, Dr. Hirotsu and her colleagues evaluated data on patients with CLL who underwent at least one Mohs surgery procedure at UCSD Dermatologic Surgery over 10 years. Of the 362 Mohs cases among 98 patients with CLL, 32 cases had at least one complication. Patients on anticoagulants, including antiplatelet agents, Coumadin, and direct oral anticoagulants (DOACs), not surprisingly, had higher rates of complications, particularly bleeding.
However, those treated with ibrutinib had the highest rates of complications among all of the patients (40.6%), with all of their complications involving bleeding-related events. In comparison, the complication rates, for instance, of patients treated with antiplatelets were 21.9%; Coumadin, 6.2%; and DOACs, 15.6%.
The incidence of bleeding-related complications among the cases in the ibrutinib-treated patients was 30.2% compared with 13.2% among those on blood thinners and no CLL therapy (relative risk [RR], 2.08; 95% confidence interval [CI], 0.85-5.11; P = .11). “Although not statistically significant, these results could trend toward significance with larger sample sizes,” Dr. Hirotsu said.
The risk for bleeding among patients on ibrutinib compared with patients on no medications, however, was significant, with a relative risk of 39.0 (95% CI, 2.35-646; P = .011).
Of note, among 12 patients on ibrutinib who experienced bleeding complications, 7 had previously undergone Mohs surgeries when they were not taking ibrutinib and no bleeding complications had occurred in those procedures. “This may further implicate ibrutinib as a cause of the bleeding-related complications,” Dr. Hirotsu said.
In investigating the role of thrombocytopenia at the time of Mohs surgery, the authors found that, among ibrutinib-treated patients who had no complications, 30% had thrombocytopenia, compared with 70% of those who did have bleeding while on ibrutinib at the time of surgery.
“It was interesting that thrombocytopenia is more common in ibrutinib patients with bleeding-related complications, but further research needs to be done to determine the clinical relevance and possible management implications,” Dr. Hirotsu said.
In a separate study presented at the meeting, 37 patients treated with ibrutinib for CLL while undergoing cutaneous surgery that included Mohs surgery and excisions had a significantly increased bleeding complication rate compared with a control group of 64 age- and sex-matched patients with CLL undergoing cutaneous surgery: 6 of 75 procedures (8%) versus 1 of 115 procedures (0.9%; P = .02).
Those with bleeding complications while on ibrutinib were all male, older (mean age, 82.7 vs. 73.0; P = .01), and had lower mean platelet counts (104 K/mcL vs. 150.5 K/mcL; P = .03).
There were no significant differences between the case and control groups in terms of anatomic site, type of procedure (Mohs versus excision), tumor diagnosis, lesion size, or type of reconstruction, while the control group was more likely to be on aspirin or other anticoagulants (P < .0001).
In an interview, senior author Nahid Y. Vidal, MD, a Mohs surgeon and dermatologic oncologist at the Mayo Clinic, Rochester, Minn., said that “the take-home message is that patients on ibrutinib should be considered higher risk for bleeding events, regardless of whether they are having a simpler surgery [excision] or more involved skin surgery procedure [Mohs with flap].”
Holding treatment
To offset the bleeding risk, Dr. Vidal notes that holding the treatment is considered safe and that the manufacturer recommends holding ibrutinib for at least 3-7 days pre- and post surgery, “depending on type of surgery and risk of bleeding.”
“In our institution, with the hematologist/oncologist’s input, we hold ibrutinib for 5 days preop and 3 days post op, and have not had bleed complications in these patients,” she said, noting that there were no bleeding events in the patients in the study when ibrutinib was held.
Likewise, Dr. Hirotsu noted that at her center at UCSD, patients on ibrutinib are asked during the preop call to hold treatment for 3 days before and after Mohs surgery – but are advised to discuss the decision with their hematologist/oncologist for approval.
The measure isn’t always successful in preventing bleeding, however, as seen in a case study describing two patients who experienced bleeding complications following Mohs surgery despite being taken off ibrutinib 3 days prior to the procedure.
The senior author of that study, Kira Minkis, MD, PhD, department of dermatology, Weill Cornell/New York Presbyterian, New York, told this news organization that her team concluded that in those cases ibrutinib perhaps should have been held longer than 3 days.
“In some cases, especially if the Mohs surgery is a large procedure with a more advanced reconstruction, such as a large flap, it might be more prudent to continue it longer than 3 days,” Dr. Minkis said. She noted that the high bleeding risk observed in the studies at ACMS was notable – but not unexpected.
“I’m not that surprised because if you look at the hematologic literature, the risk is indeed pretty significant, so it makes sense that it would also occur with Mohs surgeries,” she said.
She underscored that a 3-day hold of ibrutinib should be considered the minimum, “and in some cases, it should be held up to 7 days prior to surgery, depending on the specific surgery,” with the important caveat of consulting with the patient’s hematology team.
“Multidisciplinary decision-making is necessary for these cases, and the interruption of therapy should always be discussed with their hematology team,” she added. That said, Dr. Minkis noted that “I’ve never had a hematologist who had any concerns for withholding ibrutinib even for a week around the time of a surgery.”
Dr. Hirotsu, Dr. Vidal, and Dr. Minkis reported no relevant financial relationships.
