The diagnosis in this patient is ulcerative colitis (UC) on the basis of physical examination, laboratory values, and endoscopy. However, this patient has the most extensive form, pancolitis, which means that inflammation and damage extend the entire length of the colon. 

The diagnosis of UC is best made with endoscopy and mucosal biopsy for histopathology. Characteristic findings are abnormal erythematous mucosa, with or without ulceration, extending from the rectum to a part or all of the colon and uniform inflammation, without intervening areas of normal mucosa (skip lesions tend to characterize Crohn disease). Contact bleeding may also be observed, with mucus identified in the lumen of the bowel.

The bowel wall is thin or of normal thickness, but edema, accumulation of fat, and hypertrophy of the muscle layer may give it the appearance of a thickened bowel wall. The disease is largely confined to the mucosa and, to a lesser extent, the submucosa.

Laboratory studies are helpful to exclude other diagnoses and assess the patient's nutritional status, and serologic markers aid in the differential diagnosis of inflammatory bowel disease. Radiographic imaging has an important role in differentiation of UC from Crohn disease. Fistulas or the presence of small bowel disease are seen only in Crohn disease. 

According the American Gastroenterological Association, drug classes for the long-term management of moderate to severe UC include tumor necrosis factor–alpha antagonists, anti-integrin agent (vedolizumab), Janus kinase inhibitor (tofacitinib), interleukin 12/23 antagonist (ustekinumab), and immunomodulators (thiopurines, methotrexate). Most drugs that are initiated for the induction of remission are continued as maintenance therapy if they are effective. This is not the case, however, if corticosteroids or cyclosporine are necessary to induce remission.

This patient's pancolitis presentation is also acute and severe, defined as more than 6 bloody bowel movements per day plus one of the following: fever > 100.4 °F, hemoglobin level < 10.5 g/dL, heart rate > 90 beats/min, erythrocyte sedimentation rate > 30 mm/h, or C-reactive protein level > 30 mg/dL). This requires hospitalization and treatment with intravenous corticosteroids (hydrocortisone 400 mg/d or methylprednisolone 60 mg/d). Considered a medical emergency, the situation requires prompt recognition and multidisciplinary management. In patients who fail therapy with 3-5 days of intravenous corticosteroids, medical rescue therapy is indicated with either infliximab or cyclosporine. If all measures fail, the patient may need emergency surgery.

Hospitalized patients with acute severe UC have short-term colectomy rates of 25%-30%.

On the basis of the history, examination, and investigations, retinal migraine was diagnosed according to the International Classification of Headache Disorders, third edition (1.2 migraine with aura; 1.2.4 retinal migraine). This classification system describes retinal migraine as a subtype of migraine with aura. 

Retinal migraine (also called ophthalmic or ocular migraine) is relatively rare but is sometimes a cause of transient monocular blindness in young adults. It manifests as recurrent attacks of unilateral visual disturbance (positive symptoms) or blindness (negative symptoms) lasting from minutes to 1 hour, associated with minimal or no headache. 

Some patients describe a positive visual symptom/disturbance in a mosaic pattern of scotomata that gradually enlarge, producing total or near-total unilateral visual loss. Precipitating factors may include emotional stress, hypertension, and hormonal contraceptive pills, as well as exercise, high altitude, dehydration, smoking, hypoglycemia, and hyperthermia.

Retinal migraine is believed to result from transient vasospasm of the choroidal or retinal arteries. A history of recurrent attacks of transient monocular visual disturbance or blindness, with or without a headache and without other neurologic symptoms, can suggest retinal migraine. A personal or family history of migraine can confirm the diagnosis.

Ruling out eye disease or vascular causes, especially when risk factors for arteriosclerosis exist, is important; that is, the condition must be differentiated from ocular or vascular causes of transient monocular blindness, mainly carotid artery disease. 

Carotid duplex ultrasonography, transcranial Doppler ultrasonography, magnetic resonance angiography, or CT angiography of the brain may be helpful. Fluorescein or cerebral angiography is rarely necessary. A hypercoagulability workup and evaluation of the erythrocyte sedimentation rate may be useful in excluding other coagulation disorders associated with retinal vasculopathy.

Regarding management, calcium-channel blockers have shown some efficacy. Even in patients with low blood pressure, nifedipine 10-20 mg/d is generally tolerated. From the available literature on treatment of this condition, it is recommended that triptans, ergots, and beta-blockers be used with caution or avoided in patients with retinal migraine owing to the potential for exacerbating vasoconstriction of the retinal artery. Transient vision loss in retinal migraine has been associated with future onset of permanent vision loss from occlusive conditions such as central retinal artery occlusion and branch retinal artery occlusion.

The American Diabetes Association (ADA) position statement on diabetic retinopathy states that hyperglycemia has been the most consistently associated risk factor for retinopathy. A large and consistent set of observational studies and clinical trials confirms the association of poor glucose control and retinopathy. 

The Diabetes Control and Complications Trial (DCCT), a randomized controlled clinical trial of intensive glycemic control vs conventional glycemic control in people with type 1 diabetes (T1D), demonstrated that intensive therapy reduced the development or progression of diabetic retinopathy by 34%-76%. The DCCT also demonstrated a definitive relationship between hyperglycemia and diabetic microvascular complications, including retinopathy. Early treatment with intensive therapy was effective.

The UK Prospective Diabetes Study (UKPDS) of patients with newly diagnosed T2D conclusively demonstrated that improved blood glucose control reduced the risk for retinopathy and nephropathy and, possibly, neuropathy. The overall microvascular complication rate was decreased by 25% in patients receiving intensive therapy vs conventional therapy. Epidemiologic analysis of the UKPDS data showed a continuous relationship between the risk for microvascular complications and glycemia, such that every percentage-point decrease in A1c (eg, 9% to 8%) was associated with a 35% reduction in the risk for microvascular complications.

More recently, the ACCORD trial of medical therapies demonstrated that intensive glycemic control reduced the risk for progression of diabetic retinopathy in people with T2D of 10 years' duration. This study included 2856 ACCORD participants enrolled in the ACCORD Eye Study and followed for 4 years.

The ADA recommends screening by an ophthalmologist for diabetic retinopathy within 5 years of the diagnosis of T1D and at the time of diagnosis of T2D. Women with preexisting diabetes who are planning pregnancy or who have become pregnant should be screened before pregnancy or in the first trimester.

While optimization of blood glucose, blood pressure, and serum lipid levels in conjunction with appropriately scheduled dilated eye examinations can substantially decrease the risk for vision loss from diabetic retinopathy, a significant proportion of those affected with diabetes develop diabetic macular edema or proliferative changes that require intervention. ADA treatment recommendations are:

•    Refer patients with any level of macular edema, severe nonproliferative diabetic retinopathy (a precursor of proliferative diabetic retinopathy), or proliferative diabetic retinopathy to an ophthalmologist knowledgeable and experienced in the management and treatment of diabetic retinopathy.
•    Laser photocoagulation therapy reduces the risk for vision loss in patients with high-risk proliferative diabetic retinopathy and, in some cases, severe nonproliferative diabetic retinopathy.
•    Intravitreous injections of anti–vascular endothelial growth factor are indicated for central-involved diabetic macular edema, which occurs beneath the foveal center and may threaten reading vision.

On the basis of the patient's medical history and presentation, this is probably a case of uveitis, a common extra-articular manifestation of psoriatic disease. In fact, the presence of uveitis can help distinguish PsA from osteoarthritis. Uveitis is characterized by inflammation of the uvea tract, with the retina, optic nerve, vitreous body, and sclera potentially becoming inflamed as well. Among patients with PsA, the prevalence of uveitis rises with ongoing disease duration, though the condition may also precede the development of PsA in patients with psoriasis, and is common among patients with severe psoriatic disease in Western and Asian populations. Overall, the prevalence of uveitis has been estimated to be 6%-9%. HLA-B27 genotype is strongly associated with uveitis in patients with concomitant PsA. 

Symptoms of uveitis, as seen in the present case, include blurred vision, photophobia, pain, and ciliary flush. The condition is classified as anterior, intermediate, posterior, or panuveitis, with the majority of cases diagnosed as anterior. In anterior uveitis, the inflamed pupil may become constricted or take on an irregular shape caused by iris adhesions to the anterior lens capsule. Uveitis in PsA is bilateral and has a chronic relapsing course. Onset is typically insidious.

Workup for uveitis should comprise visual acuity testing, slit lamp biomicroscopy, measurement of intraocular pressures, and a dilated eye exam. Conditions in the differential which threaten a patient's sight include retinal vasculitis, vitritis, cystoid macular edema, Behçet disease, and tubulo-interstitial nephritis. Other autoimmune diseases which can cause uveitis with systemic manifestations (multiple sclerosis, sarcoidosis, lupus) should be investigated. Infectious causes must also be eliminated. However, considering this patient's history of psoriatic disease, uveitis should be highly suspected.

Uveitis demands urgent treatment to control ocular inflammation. Tumor necrosis factor (TNF) inhibitors are the recommended first-line and second-line treatment for PsA, including in patients with complications such as uveitis. However, etanercept should not be used as it is less effective than adalimumab or other TNF inhibitors for uveitis. Because uveitis may sometimes respond to MTX therapy, patients with severe PsA may use a biologic agent in combination with MTX if they have had a partial response to current MTX therapy, as recommended by the American College of Rheumatology.

Based on the patient's presentation and workup, the likely diagnosis is adenosquamous carcinoma of the lung, a relatively rare subtype of non–small cell lung cancer (NSCLC). Adenosquamous carcinoma displays qualities of both squamous cell carcinoma and adenocarcinoma; for definitive diagnosis, the cancer must contain 10% of each of these major NSCLC subtypes. Maeda and colleagues concluded that adenosquamous carcinoma occurs more frequently among men and that the age at the time of diagnosis is higher among such cancers compared with adenocarcinoma. Several studies have confirmed that adenosquamous carcinoma of the lung is also more prevalent among smokers. 

Though a diagnosis of adenosquamous carcinoma may be suspected after small biopsies, cytology, or excisional biopsies, definitive diagnosis necessitates a resection specimen. If any adenocarcinoma component is observed in a biopsy specimen that is otherwise squamous, as in the present case, this finding is an indication for molecular testing. Epidermal growth factor receptor (EGFR) mutations may be present in adenosquamous carcinoma cancers, despite a majority of cancers with EGFR mutations being among nonsmokers or former light smokers with adenocarcinoma histology. In addition, even for patients diagnosed with squamous cell carcinoma, adenosquamous carcinoma should be considered if genetic testing suggests EGFR mutations.

Relative to adenocarcinoma and squamous cell carcinoma, adenosquamous carcinoma has higher grade malignancy, more advanced postoperative stage, and stronger lymph nodal invasiveness. In terms of treatment, surgical resection is the curative option for adenosquamous carcinoma of the lung, with lobectomy with lymphadenectomy considered for first-line treatment. Though the most beneficial chemotherapy regimen for patients with adenosquamous carcinoma of the lung remains the subject of investigation, platinum-based doublet chemotherapy is the current standard treatment option. EGFR tyrosine kinase inhibitors may be an effective option for EGFR-positive patients.

Based on the patient's presentation and workup, the likely diagnosis is adenosquamous carcinoma of the lung, a relatively rare subtype of non–small cell lung cancer (NSCLC). Adenosquamous carcinoma displays qualities of both squamous cell carcinoma and adenocarcinoma; for definitive diagnosis, the cancer must contain 10% of each of these major NSCLC subtypes. Maeda and colleagues concluded that adenosquamous carcinoma occurs more frequently among men and that the age at the time of diagnosis is higher among such cancers compared with adenocarcinoma. Several studies have confirmed that adenosquamous carcinoma of the lung is also more prevalent among smokers. 

Though a diagnosis of adenosquamous carcinoma may be suspected after small biopsies, cytology, or excisional biopsies, definitive diagnosis necessitates a resection specimen. If any adenocarcinoma component is observed in a biopsy specimen that is otherwise squamous, as in the present case, this finding is an indication for molecular testing. Epidermal growth factor receptor (EGFR) mutations may be present in adenosquamous carcinoma cancers, despite a majority of cancers with EGFR mutations being among nonsmokers or former light smokers with adenocarcinoma histology. In addition, even for patients diagnosed with squamous cell carcinoma, adenosquamous carcinoma should be considered if genetic testing suggests EGFR mutations.

Relative to adenocarcinoma and squamous cell carcinoma, adenosquamous carcinoma has higher grade malignancy, more advanced postoperative stage, and stronger lymph nodal invasiveness. In terms of treatment, surgical resection is the curative option for adenosquamous carcinoma of the lung, with lobectomy with lymphadenectomy considered for first-line treatment. Though the most beneficial chemotherapy regimen for patients with adenosquamous carcinoma of the lung remains the subject of investigation, platinum-based doublet chemotherapy is the current standard treatment option. EGFR tyrosine kinase inhibitors may be an effective option for EGFR-positive patients.

On the basis of the patient's presentation and history, this is probably a case of Crohn disease. Considering that the age of onset of Crohn disease has a bimodal distribution, this case is representative of late-onset disease. Among patients diagnosed with Crohn disease, the first peak is seen between 15 and 30 years of age, whereas the second peak, occurring in up to 15% of diagnoses, is observed mainly in women between 60 and 70 years of age. A significant proportion of Crohn disease cases are heritable. Patients of Ashkenazi Jewish descent are at higher risk of developing the condition than any other ethnic group.

According to American Gastroenterological Association guidelines, a diagnosis of inflammatory bowel disease (IBD) should be considered in older patients who present with diarrhea, rectal bleeding, urgency, abdominal pain, or weight loss. Fecal calprotectin or lactoferrin measurement may help identify patients who warrant further endoscopic evaluation. Colonoscopy is indicated for patients presenting with chronic diarrhea or hematochezia due to suspected IBD, microscopic colitis, or colorectal neoplasia.

Upon further workup for IBD, signs that suggest Crohn disease rather than ulcerative colitis (UC) are sparing of the rectum; discontinuous involvement with skip areas, deep, linear, or serpiginous ulcers of the colon; strictures; fistulas; or granulomatous inflammation. Antiglycan antibodies are more prevalent in Crohn disease than in ulcerative colitis, but they are not sensitive. Weight loss, perineal disease, fistulae, and obstruction are common in Crohn disease but uncommon in UC.

In treating Crohn disease among older adults, systemic corticosteroids are not indicated for maintenance therapy, though they may be used for induction therapy. When possible, nonsystemic corticosteroids should be used, or, if the phenotype prevents their use, early biological therapy. The decision to treat a patient with immunosuppressive drugs should be based on age, functional status, and comorbidities. Immunomodulatory treatments with lower risks for infection and cancer may be safer for patients with late-onset disease. For maintenance of remission, thiopurine monotherapy may be used, with consideration given to its risk for nonmelanoma skin cancers and lymphoma in older patients.

On the basis of the patient's presentation, family history, and personal history of headache, she seems to be presenting with hemiplegic migraine, an uncommon migraine subtype characterized by recurrent headaches associated with temporary unilateral hemiparesis or hemiplegia. The hemiparesis may resolve before the headache, as seen in the present case, or it may persist for days to weeks. These episodes are sometimes accompanied by ipsilateral numbness, tingling, or paresthesia, with or without a speech disturbance. Visual defects (ie, scintillating scotoma and hemianopia) and aphasia may occur.

Hemiplegic migraine can be sporadic or familial. Familial hemiplegic migraine is the only migraine subtype for which an autosomal dominant mode of inheritance has been identified. The onset is generally in adolescence between 12 and 17 years of age, with an estimated prevalence of 0.01%. Female patients are more likely to have these types of migraines.

Diagnosis of hemiplegic migraine is centered on exclusion of other possible causes of headache with motor weakness. When a patient presents with motor deficit, these symptoms can also be the result of a secondary headache rather than a primary headache disorder. Because of this neurologic aspect of presentation, the differential diagnosis is broad and should span other migraine subtypes, inflammatory or metabolic disorders, and mitochondrial diseases, as well as any condition that shows neurologic deficits without radiologic alterations. Pediatric patients with hemiplegic migraine are often misdiagnosed with epilepsy. Compared with hemiplegic migraine, seizures are much more brief, and any associated hemiparesis is usually characterized by limb jerking, head turning, and loss of consciousness. Of note, up to 7% of patients with familial hemiplegic migraine do eventually develop epilepsy. Although there are no telltale pathognomonic clinical, laboratory, or radiologic findings of hemiplegic migraine, electroencephalography may show asymmetric slow-wave activity contralateral to the hemiparesis. 

In hemiplegic migraine, acute treatment options include antiemetics, NSAIDs, and nonnarcotic pain relievers; triptans and ergotamine preparations are contraindicated in this setting because of their potential vasoconstrictive effects. Even if episode frequency is low, the American Headache Society advises that prophylactic treatment should also be considered in the management of uncommon migraine subtypes such as this one.

The 2020 Kidney Disease Improving Global Outcomes (KDIGO) diabetes management in CKD guideline states that most patients with diabetic nephropathy and an eGFR  ≥ 30 mL/min/1.73 m² benefit from treatment with both metformin and a sodium-glucose cotransporter 2 (SGLT2) inhibitor, which have been demonstrated to offer substantial benefits in reducing the risks for diabetic nephropathy and cardiovascular disease.

In patients who do not reach individualized targets with metformin and an SGLT2 inhibitor, or who are unable to use these medications, a long-acting glucagon-like peptide 1 (GLP-1) receptor antagonist may be used.

Metformin should be administered with caution to patients with CKD because it may increase the risk for lactic acidosis. It is contraindicated in patients with an eGFR < 30, but this patient's eGFR is adequate. Many clinicians might use a lower metformin dosage (1500 mg) as a precaution. Given how high his A1c is, adding a GLP-1 receptor antagonist is probably going to be needed because an SGLT2 inhibitor is only intermediate in terms of glucose reduction. 

For control of his hypertension, the American Diabetes Association recommends either an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB) as first-line treatment. However, one agent alone is unlikely to control this patient's hypertension. At his level of eGFR, a thiazide diuretic is unlikely to be very effective. Therefore, a loop diuretic should be initiated with the ACE inhibitor or ARB, especially because he has edema.

On the basis of the patient's history and presentation, this is likely a case of adenocarcinoma of the prostate. Although most patients with prostate cancer are diagnosed on screening, when localized symptoms do occur, they may include urinary frequency, decreased urine stream, urinary urgency, and hematuria. In some cases, these signs and symptoms may well be related to age-associated prostate enlargement or other conditions; benign prostatic hyperplasia, for example, can manifest in urinary symptoms and even elevate PSA (but because this patient does not report pain, nonbacterial prostatitis is unlikely). Symptomatic patients older than 50 years, such as the one in this case, should be screened for prostate cancer. Those with a PSA > 10 ng/mL are more than 50% likely to have prostate cancer. 

National Comprehensive Cancer Network guidelines advise that needle biopsy of the prostate is indicated for tissue diagnosis in those with elevated PSA levels, preferably via a transrectal ultrasound. MRI can be used to assess lesions that are concerning for prostate cancer prior to biopsy. Lesions are then assigned Prostate Imaging Reporting and Data System (PI-RADS) scores depending on their location within the prostatic zones. A pathologic evaluation of the biopsy specimen will determine the patient's Gleason score. PSA density and PSA doubling time should be collected as well. The clinician should ask about high-risk germline mutations and estimate life expectancy because course of treatment is largely based on risk assessment.

Standard treatments for clinically localized prostate cancer include watchful waiting, active surveillance, radical prostatectomy, and radiation therapy. Active surveillance is often recommended for those who have very-low-risk disease because of the slow growth of certain types of prostate cancer. Radical prostatectomy is a viable option for any patient with localized disease that can be completely excised surgically, provided the patient has a life expectancy of 10 or more years and no serious comorbidities. In some patients, radical prostatectomy may be followed by radiation with or without a short course of hormone treatment, depending on risk factors for recurrence. Radiation therapy is also potentially curative in localized prostate cancer and may be delivered in the form of external-beam radiation therapy or brachytherapy. For asymptomatic patients who are older and/or have other serious underlying conditions, observation may be recommended.

On the basis of the patient's presentation, history, and imaging results, the likely diagnosis is metastatic small cell lung cancer (SCLC). Most patients with SCLC present with hematogenous metastases; only about one third present with limited disease confined to the chest that is amenable to multimodal therapy. Patients with SCLC often present with symptoms of widespread metastases, including weight loss, bone pain, and neurologic compromise. It is uncommon for patients to present with a solitary peripheral nodule. In earlier stages, the differential diagnosis of SCLC spans other neuroendocrine lung tumors and NSCLC, in particular, basaloid carcinoma, extrapulmonary small cell tumors, and lymphoma.

Because the concentration of circulating tumor cells in SCLC is among the highest of any solid tumor, SCLC is characterized by a rapid doubling time, high growth fraction, and early development of widespread metastases. It is likely for this reason that CT screening does not seem effective in detecting early-stage SCLC. Common sites of SCLC metastasis are the contralateral lung, the brain, liver, adrenal glands, and bone. Most cases of SCLC are caused by smoking. 

Metastatic spread is often evident on radiologic exam, sometimes showing pleural and pericardial effusions. In general, workup for SCLC includes imaging (contrast-enhanced CT or F-FDG PET–CT of the chest, abdomen, and pelvis and brain MRI with contrast), blood tests (cell count, liver and kidney function, and lactate dehydrogenase), and ECG. Biopsies are generally procured by bronchoscopy with or without endobronchial ultrasonography; if accessible, a biopsy of a distal metastatic site may be obtained. Diagnosis of SCLC is confirmed by histopathologic examination via cytology.

Patients with extensive-stage SCLC are typically treated with systemic chemotherapy with or without immunotherapy. In the early stages, SCLC is very responsive to cytotoxic therapies, with response rates over 60% even in patients with metastatic disease. Until recently, the only second-line therapy for recurrent metastatic SCLC was the topoisomerase I inhibitor topotecan. However, lurbinectedin was granted accelerated approval for second-line therapy after demonstrating a 35% response rate in a single-arm phase 2 study of 105 patients. In addition, the anti–programmed cell death protein 1 monoclonal antibodies nivolumab and pembrolizumab were granted accelerated approval for third-line use. Finally, the National Comprehensive Cancer Network guidelines note that participation in clinical trials should be strongly encouraged for all patients with SCLC.

On the basis of the patient's presentation, history, and imaging results, the likely diagnosis is metastatic small cell lung cancer (SCLC). Most patients with SCLC present with hematogenous metastases; only about one third present with limited disease confined to the chest that is amenable to multimodal therapy. Patients with SCLC often present with symptoms of widespread metastases, including weight loss, bone pain, and neurologic compromise. It is uncommon for patients to present with a solitary peripheral nodule. In earlier stages, the differential diagnosis of SCLC spans other neuroendocrine lung tumors and NSCLC, in particular, basaloid carcinoma, extrapulmonary small cell tumors, and lymphoma.

Because the concentration of circulating tumor cells in SCLC is among the highest of any solid tumor, SCLC is characterized by a rapid doubling time, high growth fraction, and early development of widespread metastases. It is likely for this reason that CT screening does not seem effective in detecting early-stage SCLC. Common sites of SCLC metastasis are the contralateral lung, the brain, liver, adrenal glands, and bone. Most cases of SCLC are caused by smoking. 

Metastatic spread is often evident on radiologic exam, sometimes showing pleural and pericardial effusions. In general, workup for SCLC includes imaging (contrast-enhanced CT or F-FDG PET–CT of the chest, abdomen, and pelvis and brain MRI with contrast), blood tests (cell count, liver and kidney function, and lactate dehydrogenase), and ECG. Biopsies are generally procured by bronchoscopy with or without endobronchial ultrasonography; if accessible, a biopsy of a distal metastatic site may be obtained. Diagnosis of SCLC is confirmed by histopathologic examination via cytology.

Patients with extensive-stage SCLC are typically treated with systemic chemotherapy with or without immunotherapy. In the early stages, SCLC is very responsive to cytotoxic therapies, with response rates over 60% even in patients with metastatic disease. Until recently, the only second-line therapy for recurrent metastatic SCLC was the topoisomerase I inhibitor topotecan. However, lurbinectedin was granted accelerated approval for second-line therapy after demonstrating a 35% response rate in a single-arm phase 2 study of 105 patients. In addition, the anti–programmed cell death protein 1 monoclonal antibodies nivolumab and pembrolizumab were granted accelerated approval for third-line use. Finally, the National Comprehensive Cancer Network guidelines note that participation in clinical trials should be strongly encouraged for all patients with SCLC.
