A 36-year-old female presents to her primary care provider for tremor. She reports that she has always had a mild tremor but that she has begun noticing it more since learning to paint. She feels that she has trouble dipping her paintbrush in the paint and making precise strokes on the canvas. She has taken to painting while drinking wine, as she notices that the wine seems to improve her tremor. Her temperature is 97.6°F (36.4°C), blood pressure is 105/61 mmHg, pulse is 58/min, and respirations are 12/min. On exam, she has a high frequency bilateral hand tremor elicited on finger-to-nose testing. Her neurological exam is otherwise unremarkable. The patient is started on a new medication for her symptoms. One week later, she returns with a new complaint of abdominal pain for one day. She reports that she has noticed a darkening of her urine and now has difficulty raising her arms over her head to brush her hair. This patient was most likely treated with which of the following medications?

His laboratory results are:Sodium: 138 mEq/LPotassium: 4.0 mEq/LBicarbonate: 22 mEq/LChloride: 105 mEq/LBUN: 20 mg/dLCreatinine: 1.0 mg/dLGlucose: 98 mg/dLLeukocyte count: 10,900/mm^3Hemoglobin: 12.4 g/dLPlatelets: 280,000/mm^3Which of the following is the best treatment for this patient?
A 38-year-old woman with a history of systemic lupus erythematosus, obesity, and hyperlipidemia presents to her primary care physician for evaluation of new bilateral blisters on her hands.

The patient works in the adult entertainment industry. On examination, there are multiple flaccid blisters of the bilateral dorsal hands with hemorrhagic crusts, mild scarring, and hyperpigmentation. In addition, increased hair growth is noted on the bilateral malar cheeks. Her temperature is 99.1° F (37.3° C), pulse is 95/min, blood pressure is 130/87 mmHg, respirations are 13/min, and oxygen saturation is 98% on room air. Her laboratory results are:Serum:Na+: 140 mEq/LK+: 4.5 mEq/LCl-: 100 mEq/LHCO3-: 21 mEq/LBUN: 20 mg/dLCreatinine: 1.1 mg/dLGlucose: 104 mg/dLLeukocyte count: 9,000/mm^3Hemoglobin: 12.4 g/dLPlatelets: 400,000/mm^3Anti-nuclear antibody titer 1:320Which of the following would confirm the diagnosis in this patient?
Anti dsDNA titers
Urine porphyrin levels
A 3-year-old boy is brought to his pediatrician by his mother when he developed redness, burning, itching, and exquisite pain all over his arms, lower legs, neck, and face. The mother states that she just recently began taking him to the local playground in the afternoons. She reports that she applied liberal amounts of sunscreen before and during the time outside.

The patient has experienced prior episodes of redness and pain after being outdoors, but they were relatively minor and resolved within 12 hours. She says his current presentation is much more severe with more exquisite pain than in the past. The patient's vital signs are as follows: T 37.2 C, HR 98, BP 110/62, RR 16, and SpO2 99%. Physical examination reveals edema, erythema, and petechiae over the patient's face, neck, arms, and lower legs. No blistering or scarring of the skin is noted. Which of the following is the best treatment option for this patient's condition?
Recommend use of a high SPF topical sunscreen
Begin dexamethasone taper

A 49-year-old male is referred to a dermatologist for evaluation of his lesions, shown in Figure A. Physical exam confirms that these blistering lesions are present on the patient's hands, forearms, face, and lower legs. He denies any abdominal pain but reports that he has been shaving more frequently recently due to increased hair growth on his cheeks. The patient cannot identify any changes or precipitating factors prior to the appearance of these lesions. Further work-up reveals grossly increased urinary porphyrin levels and pink-fluorescence of the urine under a Wood's lamp. Which of the following findings would be expected on biopsy of one of his skin lesions?
Thickened epidermis, absent granular cell layer, and preserved nuclei within stratum corneum
Linear, eosinophilic acid-Schifff positive globules ("Caterpillar bodies")
Neutrophilic infiltrate around capillaries with septal thickening and fibrosis of perivascular fat
Acantholysis and positive direct and indirect immunofluorescence for epidermal IgG deposition
