The Diagnosis: Pigmented Fungiform Papillae of the Tongue

Our patient’s hyperpigmentation was confined to the fungiform papillae, leading to a diagnosis of pigmented fungiform papillae of the tongue (PFPT). A biopsy was not performed, and reassurance was provided regarding the benign nature of this finding, which did not require treatment.

Pigmented fungiform papillae of the tongue is a benign, nonprogressive, asymptomatic pigmentary condition that is most common among patients with skin of color and typically develops within the second or third decade of life.^1,2 The pathogenesis is unclear, but activation of subepithelial melanophages without evidence of inflammation has been implicated.² Although no standard treatment exists, cosmetic improvement with the use of the Q-switched ruby laser has been reported.^3,4 Clinically, PFPT presents as asymptomatic hyperpigmentation confined to the fungiform papillae along the anterior and lateral portions of the tongue.^1,2

Pigmented fungiform papillae of the tongue typically is an isolated finding but rarely can be associated with hyperpigmentation of the nails (as in our patient) or gingiva.² Three different clinical patterns of presentation have been described: (1) a single well-circumscribed collection of pigmented fungiform papillae, (2) few scattered pigmented fungiform papillae admixed with many nonpigmented fungiform papillae, or (3) pigmentation of all fungiform papillae on the dorsal aspect of the tongue.^2,5,6 Pigmented fungiform papillae of the tongue is a clinical diagnosis based on visual recognition. Dermoscopic examination revealing a cobblestonelike or rose petal–like pattern may be helpful in diagnosing PFPT.^2,5-7 Although not typically recommended in the evaluation of PFPT, a biopsy will reveal papillary structures with hyperpigmentation of basilar keratinocytes as well as melanophages in the lamina propria.8 The latter finding suggests a transient inflammatory process despite the hallmark absence of inflammation.⁵ Melanocytic neoplasia and exogenous granules of pigment typically are not seen.⁸

Other conditions that may present with dark-colored macules or papules on the tongue should be considered in the evaluation of a patient with these clinical findings. Black hairy tongue (BHT), or lingua villosa nigra, is a benign finding due to filiform papillae hypertrophy on the dorsum of the tongue.⁹ Food particle debris caught in BHT can lead to porphyrin production by chromogenic bacteria and fungi. These porphyrins result in discoloration ranging from brown-black to yellow and green occurring anteriorly to the circumvallate papillae while usually sparing the tip and lateral sides of the tongue. Dermoscopy can show thin discolored fibers with a hairy appearance. Although normal filiform papillae are less than 1-mm long, 3-mm long papillae are considered diagnostic of BHT.⁹ Treatment includes effective oral hygiene and desquamation measures, which can lead to complete resolution.10

Peutz-Jeghers syndrome is a rare genodermatosis that is characterized by focal hyperpigmentation and multiple gastrointestinal mucosal hamartomatous polyps. Peutz-Jeghers syndrome should be suspected in a patient with discrete, 1- to 5-mm, brown to black macules on the perioral or periocular skin, tongue, genitals, palms, soles, and buccal mucosa with a history of abdominal symptoms.^11,12

Addison disease, or primary adrenal insufficiency, may present with brown hyperpigmentation on chronically sun-exposed areas; regions of friction or pressure; surrounding scar tissue; and mucosal surfaces such as the tongue, inner surface of the lip, and buccal and gingival mucosa.¹³ Addison disease is differentiated from PFPT by a more generalized hyperpigmentation due to increased melanin production as well as the presence of systemic symptoms related to hypocortisolism. The pigmentation seen on the buccal mucosa in Addison disease is patchy and diffuse, and histology reveals basal melanin hyperpigmentation with superficial dermal melanophages.¹³

Hereditary hemorrhagic telangiectasia is an inherited disorder featuring telangiectasia and generally appears in the third decade of life.¹⁴ Telangiectases classically are 1 to 3 mm in diameter with or without slight elevation. Dermoscopic findings include small red clots, lacunae, and serpentine or linear vessels arranged in a radial conformation surrounding a homogenous pink center.¹⁵ These telangiectases typically occur on the skin or mucosa, particularly the face, lips, tongue, nail beds, and nasal mucosa; however, any organ can be affected with arteriovenous malformations. Recurrent epistaxis occurs in more than half of patients with hereditary hemorrhagic telangiectasia.¹⁴ Histopathology reveals dilated vessels and lacunae near the dermoepidermal junction displacing the epidermis and papillary dermis.¹⁵ It is distinguished from PFPT by the vascular nature of the lesions and by the presence of other characteristic symptoms such as recurrent epistaxis and visceral arteriovenous malformations.

“More than Jews have kept Shabbat, Shabbat has kept the Jews.” – Ahad Ha’am

You should all be well rested by now. After all, we’ve just come through the festive shutdown of the holiday season where all of your pumpkin/peppermint/marshmallow flavored coffees were sipped while walking around in your jimjams at 10 a.m. It was the time of year for you to take time off to get a proper rest and be energized to get back to work. Yet, I’m not feeling it from you.

So let’s talk about burnout – just kidding, that would only make it worse. “Burned-out’’ is a hackneyed and defective phrase to describe what many of us are feeling. We are not “destroyed, gutted by fire or by overheating.” No, we are, as one of our docs put it to me: “Just tired.” Ah, a much better Old English word! “Tired” captures it. It means to feel “in need of rest.” We are not ruined, we are just depleted. We don’t need discarding. We need some rest.

Ironically, this column, like most of mine, comes to you after my having written it on a Saturday and Sunday. I also just logged on to my EMR and checked results, renewed a few prescriptions, and answered a couple messages. If I didn’t, my Monday’s work would be crushingly heavy.

Maybe I need to be more efficient and finish my work during the week. Or maybe I need to realize that work has not let up since about 600 BCE and taking one day off each week to rest is an obligation to myself, my family and my community.

I wonder if I can choose Mondays.

SAN DIEGO – If approved, a novel topical gel that combines an antibiotic, an antibacterial, and a retinoid would mark an important advance for many patients with moderate-to-severe acne, according to Lawrence F. Eichenfield, MD.

The product, known as IDP-126 and being developed by Ortho Dermatologics, is a fixed dose triple combination of clindamycin 1.2% plus benzoyl peroxide 3.1% and adapalene 0.15% being evaluated in patients nine years of age and older. According to a 2021 press release from the company, results from a second 12-week pivotal phase 3 trial showed a treatment success of 50.5% and 20.5% for IDP-126 and its vehicle, respectively, along with significant changes from baseline in inflammatory lesion count and non-inflammatory lesion count.

More recently, researchers led by Linda Stein Gold, MD, conducted a 12-week multicenter, randomized, double-blind study of IDP-126 in 741 children, adolescents, and adults with moderate to severe acne. They reported 52.5% of patients treated with IDP-126 gel achieved treatment success by week 12, with over 70% reduction in inflammatory and noninflammatory lesions.

“This will be interesting to follow as it moves along,” Dr. Eichenfield, chief of pediatric and adolescent dermatology at Rady Children’s Hospital, San Diego, said at the annual Masters of Aesthetics Symposium in a presentation on the newest topical acne treatments.

“If approved, we probably will be able to decrease our need for systemic therapies in some individuals,” he said. “It’s something that may become important in practices that mix and match between medical and procedural or surgical approaches to acne.”

Dr. Eichenfield highlighted other products for the topical treatment of acne:

• Trifarotene cream 0.005% (Aklief). In 2019, Food and Drug Administration approval made trifarotene cream the first new retinoid indicated for acne in several decades. It is indicated for the topical treatment of acne vulgaris in patients age 9 and older and has been studied in acne of the face, chest, and back.
• Tazarotene lotion 0.045% (Arazlo). The 0.1% formulation of tazarotene is commonly used for acne, but it can cause skin irritation, dryness, and erythema. The new 0.045% formulation was developed in a three-dimensional mesh matrix, with ingredients from an oil-in-water emulsion. “Many of the new acne products come with a background of vehicle delivery systems that minimize the concentration gradient, so it decreases irritation,” said Dr. Eichenfield, one of the authors of a 2021 review article on the management of acne vulgaris in JAMA. “This has very good efficacy without the traditional irritation of other tazarotene products,” Dr. Eichenfield said.
• Minocycline 4% topical foam (Amzeeq). The 2019 U.S. approval marked the first and so far only topical minocycline prescription treatment for acne. “Its hydrophobic composition allows for stable and efficient delivery of inherently unstable pharmaceutical ingredients,” he said. “It’s generally well tolerated.”
• Clascoterone cream 1% (Winlevi). This first-in-class topical androgen receptor inhibitor is approved for the treatment of acne in patients 12 years and older. It competes with dihydrotestosterone and selectively targets androgen receptors in sebocytes and hair papilla cells. “It is safe for use in men, has been studied on the face and trunk, and has been shown to inhibit sebum production, reduce secretion of inflammatory cytokines, and inhibit inflammatory pathways,” Dr. Eichenfield said.
• Micro-encapsulated benzoyl peroxide 3% and tretinoin 0.1% cream (Twyneo). This is a once-daily fixed-dose combination of tretinoin and benzoyl peroxide indicated for the treatment of acne vulgaris in patients age 9 and older. According to a press release from Sol-Gel, the manufacturer, silica (silicon dioxide) core shell structures separate micro-encapsulate tretinoin crystals and benzoyl peroxide crystals, enabling inclusion of the two active ingredients in the cream.

Dr. Eichenfield disclosed that he has been an investigator and/or consultant for Almirall, Cassiopea, Dermata, Galderma, and Ortho Dermatologics.

A new hereditary test can determine whether a cancer-disposing gene was inherited from a patient’s father or mother without the need for parental DNA, potentially improving disease screening and management.

“The presence of parental imprints in regions of the genome has been known for a long time,” study author Peter Lansdorp, MD, PhD, of the BC Cancer Research Centre in Vancouver, said in an interview. In addition, the ability of a specific sequencing technology (Strand-seq) to generate a set of DNA variants that tend to be inherited together from a single parent has been documented in several studies.

“That these two pieces can be put together to assign alleles in a patient to one of the parents without studying the DNA of the parents is a major advance,” said Dr. Lansdorp.

Principal author Steven J.M. Jones, PhD, associate director of bioinformatics at BC Cancer Research Centre, explained, “for directing cascade genetic testing, the test could be used almost immediately, even as a research test. It just guides which side of the family to focus familial genetic testing efforts on and is internally validated by the patient’s variant and later confirmed by clinical testing in the family.”

Directing cascade genetic testing to one side of the family over the other could speed time to diagnosis of more carriers and allow for more efficient use of genetic counseling resources, Dr. Jones added, especially when parents are deceased or unavailable.

The study was published online in Cell Genomics.
 

Low error rate

Determining a parent of origin for hereditary variants “is essential to evaluate disease risk when a pathogenic variant has PofO effects, that is, when a patient’s risk of disease depends on from which parent it is inherited,” the authors wrote. An example is hereditary paraganglioma-pheochromocytoma syndrome as a result of pathogenic variants in SDHD or SDHAF2 genes. Individuals with the variants are at high risk of developing certain cancers, but only if a defective gene is inherited from their father. If inherited from their mother, there is no increased risk.

The new method relies on a technique called “phased DNA methylation” at maternally and paternally imprinted gene loci, as well as chromosome length phasing of DNA sequences.

The team used five human genome “trios” – two parents and the proband (the first person in a family to receive genetic testing or counseling for a suspected hereditary risk) – to pilot the approach. They showed that the method can correctly identify the PofO with an average mismatch error rate of 0.31% for single nucleotide variants and 1.89% for insertions or deletions (indels).

“We will need to validate this technology for different genes in real-world samples from individuals of diverse backgrounds,” said Dr. Jones. The first step is to validate the technology in scenarios with immediate clinical utility, like with SDHD, where lifelong medical management is affected by knowledge of whether the variant was inherited from the mother or father.

“We would also like to quickly validate this for common hereditary cancer genes, like BRCA1, BRCA2, and Lynch syndrome–associated genes, where prediction of PofO may improve low rates of genetic testing in family members by providing more accurate estimates of their risk to carry the familial variant.”

Challenges to moving the test to the clinic, Dr. Jones said, include scaling up the technology, demonstrating clinical and economic utility, compared with existing testing approaches, “and familiarizing clinicians with a new type of test that will routinely give this added dimension of information.”
 

‘Tremendously promising technology’

Pathologist Stephen Yip, MD, PhD, of the Vancouver Coastal Health Research Institute, who was not involved in the study but disclosed that he collaborates with the authors on other grant-funded projects, said in a comment that “this is a tremendously promising technology that has immediate practical implications in the investigation of PofO of a pathogenic locus, particularly when genetic material is available only from the proband.”

However, “rigorous validation against the current gold standard of short-reading, next-generation sequencing of trios is needed prior to clinical deployment,” he said. “This will take time and effort. However, the promise of this technology is worth the effort.

“Also, there is the possibility of uncovering novel genetics during testing, which could present an ethical dilemma,” he noted. “A robust consenting and ethical framework and early involvement of an ethicist would be helpful.”

A new hereditary test can determine whether a cancer-disposing gene was inherited from a patient’s father or mother without the need for parental DNA, potentially improving disease screening and management.

“The presence of parental imprints in regions of the genome has been known for a long time,” study author Peter Lansdorp, MD, PhD, of the BC Cancer Research Centre in Vancouver, said in an interview. In addition, the ability of a specific sequencing technology (Strand-seq) to generate a set of DNA variants that tend to be inherited together from a single parent has been documented in several studies.

“That these two pieces can be put together to assign alleles in a patient to one of the parents without studying the DNA of the parents is a major advance,” said Dr. Lansdorp.

Principal author Steven J.M. Jones, PhD, associate director of bioinformatics at BC Cancer Research Centre, explained, “for directing cascade genetic testing, the test could be used almost immediately, even as a research test. It just guides which side of the family to focus familial genetic testing efforts on and is internally validated by the patient’s variant and later confirmed by clinical testing in the family.”

Directing cascade genetic testing to one side of the family over the other could speed time to diagnosis of more carriers and allow for more efficient use of genetic counseling resources, Dr. Jones added, especially when parents are deceased or unavailable.

The study was published online in Cell Genomics.
 

Low error rate

Determining a parent of origin for hereditary variants “is essential to evaluate disease risk when a pathogenic variant has PofO effects, that is, when a patient’s risk of disease depends on from which parent it is inherited,” the authors wrote. An example is hereditary paraganglioma-pheochromocytoma syndrome as a result of pathogenic variants in SDHD or SDHAF2 genes. Individuals with the variants are at high risk of developing certain cancers, but only if a defective gene is inherited from their father. If inherited from their mother, there is no increased risk.

The new method relies on a technique called “phased DNA methylation” at maternally and paternally imprinted gene loci, as well as chromosome length phasing of DNA sequences.

The team used five human genome “trios” – two parents and the proband (the first person in a family to receive genetic testing or counseling for a suspected hereditary risk) – to pilot the approach. They showed that the method can correctly identify the PofO with an average mismatch error rate of 0.31% for single nucleotide variants and 1.89% for insertions or deletions (indels).

“We will need to validate this technology for different genes in real-world samples from individuals of diverse backgrounds,” said Dr. Jones. The first step is to validate the technology in scenarios with immediate clinical utility, like with SDHD, where lifelong medical management is affected by knowledge of whether the variant was inherited from the mother or father.

In children with cystic fibrosis (CF) and homozygous for the F508 mutation, the combination of lumacaftor and ivacaftor appears generally safe, and biomarker data suggest its efficacy, according to results from a new open-label phase 3 trial.

In September, the Food and Drug Administration approved lumacaftor/ivacaftor for patients aged 1 years and above. Waiting in the wings is the triple combination of elexacaftor, tezacaftor, and ivacaftor (ETI), which is available for patients with at least one copy of the F508 mutation aged 6 and over. ETI is also being tested in younger patients.

One driving factor for early treatment is countering the malnutrition that can occur among CF patients because of poor pancreatic insufficiency and chronic inflammation. “We’ve known for many years that (being) at or above average body weight and height predict better lung function. And we’ve known for quite a while that the height-for-age percentile, in preschool years, actually predicts your lung function later, and how long you’re going to live, so nutrition is incredibly important,” said study author Susanna McColley, MD, in an interview. It’s also difficult to use lung function tests in young children, since even adults can find them challenging, she said.

“FEV₁ [forced expiratory volume in 1 second] is the strongest predictor of survival, and then nutrition is the highest predictor of FEV₁, so that’s kind of the construct. They had similar improvement in the functional measures of their pancreas and in the measures of inflammation in the gut. I think the story here is that starting a modulator early has a likelihood to have positive health effects that go forward. We can’t say that from the data in the paper. It’s a 24-week study, but looking at the pancreatic and intestinal functioning and also the fact that there was a decrease in sweat chloride is important,” said Dr. McColley, who is a professor of pediatrics in pulmonary and sleep medicine at Northwestern University, Chicago.

The study adds more evidence that earlier treatment in CF may lead to better outcomes, but the digestive improvements are an overlooked factor, according to Dr. McColley. “Even with early treatment, and even with pancreatic enzymes and supplements taken to digest food, it’s a huge burden. When they come in and say that digestion seems better, there is less bloating, things like that, these are the things that aren’t captured so much in the clinical trial data, but they’re meaningful to families,” she said.

Single-agent ivacaftor is available for children as young as 4 months, but is limited to patients with the G551D gating mutation. Most young children with CF can only be treated for symptoms.

The lack of new safety signals in the new study is reassuring, and the research presents some hope to young children who are not yet eligible to receive ETI, according to Carlos Milla, MD, who is a pediatric pulmonary physician at Stanford (Calif.) University. “We already know that the next version of this drug is much more efficacious, the triple-combination therapy. It’s a little bit like we’re falling behind when it comes to treating these young kids because we are offering right now what we know is a less effective drug as opposed to the ones that are available now down to age 6, and hopefully sometime soon down to age 2. It’s better [than] to have no treatment at all, so it’s a good start,” said Dr. Milla.

“I think this is a great bridge for babies while they’re waiting to grow up to be old enough to get [triple combination therapy] and will prevent some of the complications until they can get the even more highly effective therapy in the future,” said Jennifer Taylor-Cousar, MD, who was asked to comment on the study. Dr. Taylor-Cousar is codirector of the Adult CF Program at National Jewish Health, Denver.

She also noted that the therapy could rapidly become more important. Since the approval of elexacaftor/tezacaftor/ivacaftor in 2019, pregnancies in women with CF have increased markedly. There were 310 such pregnancies in 2019, and 675 in 2020 after the combination became generally available in November of 2019. Many of the resulting babies had false-negative CF diagnoses because the mother was taking the triple combination and the medication crossed the placenta and prevented disease progression. The drugs are present in breast milk, but when breastfeeding isn’t possible, newborns are left without a therapeutic option. “There was no approval for babies who had two copies of F508. This helps tremendously with that albeit small population, although I suspect it may grow larger over the upcoming years as we continue to see so many pregnancies in women with CF because they are so much healthier,” said Dr. Taylor-Cousar.

The study was a phase 3, open-label trial with a cohort aged 18-24 months (cohort 1, n = 14) and another aged 12-18 months (cohort 2, n = 46). Participants received a 15-day treatment with a dose based on weight at screening. Participants then underwent a 24-week treatment period with a dose determined by pharmacokinetic data collected during the initial treatment, the authors wrote in the American Journal of Respiratory and Critical Care Medicine.

A total of 95.7% of children experienced adverse events during the 24-week treatment period; 52.2% of events were mild, and 39.1% were moderate. The most frequent adverse events were cough (34.8%), infective exacerbation of CF (21.7%), pyrexia (21.7%), and vomiting (17.4%); 10.9% had elevations of alanine aminotransferase and/or aspartate aminotransferase higher than three times the upper limit of normal, and one (2.2%) had concentrations of both high enough that the study drug was discontinued.

There were significant reductions in sweat chloride concentration at week 24, suggesting strong efficacy (–29.1 mmol/L; 95% confidence interval, –34.8 to –23.4 mmol/L). Body mass, weight, and length remained normal during the 24-week treatment period, and there were trends towards improvement in biomarkers of pancreatic function and intestinal inflammation, including fecal elastase-1 (+73.1mcg/g; 95% CI, 29.40-116.80 mcg/g), serum immunoreactive trypsinogen (–295.50 mcg/g; 95% CI, –416.60 to –174.50 mcg/g), and fecal calprotectin (–106.63 mg/kg; 95% CI, –180.60 to –32.66 mg/kg)

Among Hispanic/Latinx patients with alopecia areata, the mean age at diagnosis was 33 years, 24% had concomitant atopy, and 18% had one or more coexisting autoimmune conditions, most commonly rheumatoid arthritis.

Those are among key findings from a retrospective analysis of Hispanic/Latinx patients at the University of California, Irvine (UCI) by Natasha Mesinkovska, MD, PhD, of UCI’s department of dermatology, and her coauthors. The findings were published online in the Journal of the American Academy of Dermatology.

A recent study examined the epidemiology of alopecia areata (AA) in Black patients, wrote Dr. Mesinkovska and coauthors Celine Phong, a UCI medical student, and Amy J. McMichael, MD, professor of dermatology at Wake Forest University, Winston-Salem, N.C. “A similar unmet need exists to describe the characteristics of AA in Hispanic/Latinx (H/L) patients, the prevalent majority in California,” they added.

Drawing from chart reviews, ICD codes, and documented physical exams, they retrospectively identified 197 Hispanic/Latinx patients diagnosed with AA at UCI between 2015 and 2022, including alopecia totalis and alopecia universalis.

Nearly two-thirds of patients with alopecia were female (63%), and their mean age at diagnosis was 33 years. Most patients (79%) presented with patchy pattern AA, 13% had diffuse pattern AA, and only 12% had eyebrow, eyelash, or beard involvement. The most common comorbidity in patients overall was atopy (24%), including allergic rhinitis (12%), asthma (10%), and/or atopic dermatitis (7%).

The authors found that 18% of patients had one or more coexisting autoimmune conditions, most commonly rheumatoid arthritis (9%) and thyroid disease (6%). No patients had celiac disease, myasthenia gravis, or inflammatory bowel disease, but 43% had another dermatologic condition.

In other findings, 22% of patients had vitamin D deficiency, 20% had hyperlipidemia, 18% had obesity, 16% had gastroesophageal reflux disease, and 12% had anemia. At the same time, depression, anxiety, or sleep disorders were identified in 14% of patients.

“Interestingly, the most common autoimmune comorbidity in H/L was rheumatoid arthritis, compared to thyroid disease in Black patients and overall AA patients,” the authors wrote. “This finding may be a reflection of a larger trend, as rheumatoid arthritis in the H/L population has been on the rise.”

The authors acknowledged certain limitations of the study including its small sample size and lack of a control group, and reported having no financial disclosures.

Nearly two-thirds of patients with alopecia were female (63%), and their mean age at diagnosis was 33 years. Most patients (79%) presented with patchy pattern AA, 13% had diffuse pattern AA, and only 12% had eyebrow, eyelash, or beard involvement. The most common comorbidity in patients overall was atopy (24%), including allergic rhinitis (12%), asthma (10%), and/or atopic dermatitis (7%).

The authors found that 18% of patients had one or more coexisting autoimmune conditions, most commonly rheumatoid arthritis (9%) and thyroid disease (6%). No patients had celiac disease, myasthenia gravis, or inflammatory bowel disease, but 43% had another dermatologic condition.

In other findings, 22% of patients had vitamin D deficiency, 20% had hyperlipidemia, 18% had obesity, 16% had gastroesophageal reflux disease, and 12% had anemia. At the same time, depression, anxiety, or sleep disorders were identified in 14% of patients.

“Interestingly, the most common autoimmune comorbidity in H/L was rheumatoid arthritis, compared to thyroid disease in Black patients and overall AA patients,” the authors wrote. “This finding may be a reflection of a larger trend, as rheumatoid arthritis in the H/L population has been on the rise.”

The authors acknowledged certain limitations of the study including its small sample size and lack of a control group, and reported having no financial disclosures.

Among Hispanic/Latinx patients with alopecia areata, the mean age at diagnosis was 33 years, 24% had concomitant atopy, and 18% had one or more coexisting autoimmune conditions, most commonly rheumatoid arthritis.

Those are among key findings from a retrospective analysis of Hispanic/Latinx patients at the University of California, Irvine (UCI) by Natasha Mesinkovska, MD, PhD, of UCI’s department of dermatology, and her coauthors. The findings were published online in the Journal of the American Academy of Dermatology.

A recent study examined the epidemiology of alopecia areata (AA) in Black patients, wrote Dr. Mesinkovska and coauthors Celine Phong, a UCI medical student, and Amy J.

Leave the mouthwash. Take the yogurt

Most of us have experienced some sort of bad breath. It’s common in the morning right after waking up, but it also may be a sign for underlying medical issues like dental problems or acid reflux. Wherever it comes from, we always want to get rid of it. A recent meta-analysis in BMJ Open may have found the answer in some common foods.

For those with halitosis, the basic problem is that the bacteria in their mouths are not happy about where they are. The researchers looked at 130 studies and found seven that suggested fermented food has some effect in combating bad breath.

Now when we say fermented food, we’re not talking about that science project waiting to happen in the back of the refrigerator. Think yogurt, sourdough bread, or miso soup. Anything that contains probiotic bacteria.

Matthew J. Messina, DDS, assistant professor of dentistry at Ohio State University, who was not involved with the study, told Healthline that “the whole idea behind probiotics is [bacteria replacement]. Supplant the ‘bad guys’ with the ‘good guys,’ then we’ll end up with a better result.” Essentially balancing the scales in your mouth.

It may not be a long-term solution, Dr. Messina said, but the short-term data are positive. So if you experience bad breath from time to time, try a little bowl of yogurt instead of chewing gum. If nothing else, the bacteria in your mouth will thank you.

You can talk the silly talk, but can you walk the silly walk?

The Ministry of Silly Walks sketch from Monty Python is an enduring comedy classic, and one of surprising relevance for doctors. After all, this isn’t the first time a study has analyzed the unusual strides of Mr. Putey and Mr. Teabag.

The BMJ Christmas edition truly is the gift that keeps on giving. For this plunge into the Flying Circus, the study authors recruited a small group of fairly average adults and had them walk normally around a track for 5 minutes, monitoring their oxygen intake and energy expenditure. After that, the study participants imitated Mr. Putey’s walk and then Mr. Teabag’s.

In the sketch, Mr. Teabag notes that Mr. Putey’s walk is “not particularly silly,” which is borne out in the research. When imitating Mr. Putey’s walk, oxygen intake and energy expenditure were barely higher than a normal walk, not enough to achieve a meaningful difference. Hopefully he’ll get that government grant to further develop his silly walk, because right now Mr. Putey’s walk simply doesn’t cut it.

Mr. Teabag’s walk is a different story and the very image of inefficiency. Oxygen intake was 2.5 times higher than during the normal walk, and energy expenditure was noticeably higher (8 kcal in men and 5.2 kcal in women). In fact, the walk was so inefficient and its effect so drastic it actually reached the level of vigorous exercise. Thanks to this, the study authors noted that just 11 minutes a day of walking like Mr. Teabag would be enough to reach the general goal of 75 minutes of vigorous exercise per week. Boosting that to 12-19 minutes would increase daily energy expenditure by 100 kcal.

The study authors wrote, “Had an initiative to promote inefficient movement been adopted in the early 1970s, we might now be living among a healthier society. Efforts to promote higher energy – and perhaps more joyful – walking should ensure inclusivity and inefficiency for all.” We think they just advocated for a real-life Ministry of Silly Walks. Well, there have been worse ideas. Just look at Twitter.
 

When efficient gut microbes go bad

With the latest news from the Ministry of Silly Walks, is it time for humans to embrace all things inefficient? Maybe.

Turns out that individuals with more efficient digestive systems – those that extract more energy from the fuel supplied to them by the busy mouths above – tend to gain more weight than those with less efficient guts, even when they eat the same food, according to a recent study published in Microbiome.

The researchers took a look at the composition of gut microbes in a group of 85 volunteers and found that about 40% had microbiomes dominated by Bacteroides bacteria, which are more effective at extracting nutrients from food. That group also weighed 10% more on average, amounting to an extra 9 kg.

In a rather blatant demonstration of efficiency, the investigators also measured the speed of the participants’ digestion, as they had hypothesized that those with the longest digestive travel times would be the ones who harvested the most nutrition from their food. That was not the case.

The study subjects with the most efficient gut bacteria “also have the fastest passage through the gastrointestinal system, which has given us something to think about,” senior author Henrik Roager of the University of Copenhagen said in a written statement.

You know what gives us something to think about? Stool energy density and intestinal transit time and faecal bacterial cell counts, that’s what. Ick. Sometimes science is gross.

Here’s another thought, though: Seeing faecal instead of fecal is kind of funny to our American eyes, but adding that extra letter is also inefficient, which could mean that it’s good. So, in the spirit of embracing the inefficient as a new year begins, we’re resolving to wrap our editorial arms around faecal and the faeces it represents. Well, not literally, of course. More like we’re embracing the spirit of faeces.

Congress averted bigger reductions in Medicare’s future payments for clinicians in its massive, year-end spending bill, but physicians will still see a 2% cut in a key payment variable in 2023.

The bill also authorizes new policies regarding accelerated drug approvals and substance use disorder treatment.

The House voted 225-201 to clear a wide-ranging legislative package, known as an omnibus, for President Joe Biden’s signature. The Senate voted 68-29 to approve the measure.

Clinicians had been facing as much as 8.5% in cuts to certain factors that set their Medicare payment. The American Medical Association credited an advocacy campaign it joined with more than 150 organizations with fending off the much-feared reimbursement cuts. The 2% trim for 2023 will decline to 1.25% for 2024.

These reductions will hit as many clinicians face the toll on rising costs for running their practices, as Congress has not included inflation-based payment adjustments in Medicare’s physician payment rule, the AMA said.

“Congress must immediately begin the work of long-overdue Medicare physician payment reform that will lead to the program stability that beneficiaries and physicians need,” AMA President Jack Resneck, MD, said in a statement.

While the omnibus bill blocks 6.5% of Medicare payment cuts originally slated to take effect in 2023, it still puts “untenable strain” on primary care clinicians, said Tochi Iroku-Malize, MD, MPH, president of the American Academy of Family Physicians, in a statement.

“However, we’re pleased to see several provisions that will improve access to care, including bolstering mental health services, extending telehealth, and expanding Medicaid and CHIP coverage,” Dr. Iroku-Malize added.
 

New health care policies in omnibus

Lawmakers adopted many health care policy changes in the omnibus package, which contained 12 overdue spending bills for fiscal year 2023. (Much of the federal government has been funded through stop-gap measures since this budget year began on Oct. 1.) The final measure runs to more than 4,100 pages in PDF form.

House Energy and Commerce Chairman Frank Pallone Jr. (D-NJ) said the health care provisions will:

• Expand patient access to opioid addiction treatment by making it easier for clinicians to dispense buprenorphine for opioid use disorder maintenance or detoxification treatment
• Require health care providers to complete a training requirement on identifying and treating patients with substance use disorders
• Guarantee 12 months of continuous Medicaid coverage for 40 million children
• Provide 2 years of additional Children’s Health Insurance Program (CHIP) funding
• Permanently extend the option for states to offer 12 months of Medicaid coverage to new mothers
• Continue Medicare’s expanded access to telehealth by extending COVID-19 telehealth flexibilities through Dec. 31, 2024.

FDA’s accelerated approval

The omnibus also will shorten the period of uncertainty patients and clinicians face with medicines cleared under the accelerated approval pathway.

The Food and Drug Administration uses accelerated approvals to give conditional clearances to medicines for fatal and serious conditions based on limited evidence signaling a potential benefit. Companies are expected to continue research needed to prove whether promising signals, such as stemming tumor growth, benefits patients.

Concerns have mounted when companies delay confirmatory trials or try to maintain accelerated approvals for drugs that fail those trials.

Mr. Pallone said the omnibus contains provisions that:

• Require the FDA to specify conditions for required post-approval studies
• Authorize the FDA to require post-approval studies to be underway at the time of approval or within a specified time period following approval.
• Clarify and streamline current FDA authority to withdraw approvals when sponsors fail to conduct studies with due diligence.

Reshma Ramachandran, MD, MPP, MHS, who serves as the chair of the Doctors for America’s FDA Task Force, told this news organization that she was pleased to see these provisions pass. She had been disappointed they were not included earlier this year in the latest Prescription Drug User Fee Act reauthorization.

The provisions in the omnibus make “clear what steps the FDA can take to remove an unproven drug off the market should manufacturers fail to complete these studies or demonstrate meaningful clinical benefit,” Dr. Ramachandran wrote in an email.

Dr. Ramachandran said she hopes lawmakers build on these steps in the future. She suggested Congress add a mandate to require drug labels to clearly state when the FDA is still waiting for evidence needed to confirm benefits of medicines cleared by accelerated approval.

“Nevertheless, Congress in including and, hopefully, passing these reforms has made it clear that drug companies need to provide meaningful evidence that their accelerated approval drugs work in patients and FDA can take action to protect patients should this not occur,” Dr. Ramachandran wrote.

Clinicians in the United States are reporting more cases of invasive group A streptococcal infection (iGAS) in children, according to an alert from the Centers for Disease Control and Prevention. These infections are rare but can be deadly, and they can affect adults as well as children.

Health care providers should consider this bacterial infection as a possible cause of severe illness in children and adults, including those with recent or co-occurring viral respiratory infections, the agency advised in a Dec. 22 alert.

In some cases, iGAS manifests as persistent or worsening symptoms after a patient with a known viral infection initially starts to show signs of improvement, according to the agency.

In November, the CDC was notified about a possible increase in cases of pediatric iGAS at a hospital in Colorado. Since then, two surveillance systems – the Infectious Diseases Society of America’s Emerging Infections Network and the CDC’s Active Bacterial Core Surveillance System – have detected potential increases in pediatric iGAS cases in other states.

The uptick has coincided with “increased circulation of respiratory syncytial virus (RSV), influenza viruses, SARS-CoV-2, and other respiratory viruses,” the advisory stated. “While the overall number of cases has remained relatively low and iGAS infections remain rare in children, [the] CDC is investigating these reports.”
 

Not just strep throat

Group A Streptococcus bacteria can cause strep throat and infections in skin and soft tissue. The pathogens also can lead to uncommon but severe diseases, such as sepsis, streptococcal toxic shock syndrome, and necrotizing fasciitis, according to the CDC. The severe illnesses “are associated with high mortality rates and require immediate treatment, including appropriate antibiotic therapy,” the agency said.

Groups at higher risk for iGAS include people aged 65 years or older, American Indian and Alaska Native populations, residents of long-term care facilities, those with wounds or skin disease, people who inject drugs, and people experiencing homelessness.

People with medical conditions such as diabetes, cancer, immunosuppression, and chronic kidney, heart, or respiratory disease also are at increased risk.

Invasive strep A infections initially decreased during the COVID-19 pandemic amid measures to reduce the spread of disease, such as masking and social distancing. But since September, monthly cases have exceeded those in 2020 and 2021. “It is too early to determine whether this rise is beyond what would be expected for pre-COVID” seasonal patterns, the CDC said.
 

Recommendations

Because iGAS can occur after the flu or chickenpox, health care providers should offer influenza and varicella vaccinations to all eligible people who are not up to date with their vaccines.

In addition, clinicians should educate patients about symptoms of iGAS that require urgent medical attention, including necrotizing fasciitis, cellulitis, and toxic shock syndrome.

They also should obtain cultures for suspected cases of iGAS as clinically indicated, follow guidelines for the diagnosis and treatment of strep throat, and be aware of alternative ways to treat strep throat in children amid a shortage of amoxicillin suspension.

Researchers have reported more cases of iGAS in the United Kingdom this year, as well. According to the UK Health Security Agency, 74 deaths, including 16 children, in England have been attributed to iGAS since September.

“We know that this is concerning for parents, but I want to stress that while we are seeing an increase in cases in children, this remains very uncommon,” UKHSA Deputy Director Colin Brown said in a news release. “There are lots of winter bugs circulating that can make your child feel unwell that mostly aren’t cause for alarm. However, make sure you talk to a health professional if your child is getting worse after a bout of scarlet fever, a sore throat, or respiratory infection.”

A fever that doesn’t resolve, dehydration, extreme tiredness, and difficulty breathing are signs to watch out for, Dr. Brown said.

A common food dye found in candy, soft drinks, and some cereals, known as Allura Red, can lead to inflammatory bowel diseases, Crohn’s disease, and other health problems, new research shows.

Long-term ingestion of the dye disrupts gut function, causing a series of changes that lead to a higher risk of colitis, according to the research from McMaster University, Hamilton, Ont. The findings were published in Nature Communications.

The dye is also known as FD&C Red 40 and Food Red 17. It adds color and texture and is often used to attract children, according to a press release on Eurekalert.

“This study demonstrates significant harmful effects of Allura Red on gut health and identifies gut serotonin as a critical factor mediating these effects. These findings have important implications in the prevention and management of gut inflammation,” said senior author Waliul Khan, MBBS, PhD, a professor in the McMaster department of pathology and molecular medicine.

“What we have found is striking and alarming, as this common synthetic food dye is a possible dietary trigger for IBDs,” he said. “The literature suggests that the consumption of Allura Red also affects certain allergies, immune disorders, and behavioural problems in children, such as attention deficit hyperactivity disorder.”

The human diet in Western cultures, with its reliance on processed fats, red and processed meat, and low fiber, contributes to IBDs as well, Dr. Khan said.

Food dyes such as Allura Red have been used more and more in recent years. Their effect on gut health hasn’t been studied much.
