A Case of Drug-Induced Stevens-Johnson Syndrome.

INTRODUCTION: Stevens-Johnson syndrome is a rare but consequential and often life-threatening disorder that is most often drug-induced. CASE PRESENTATION: An 81-year-old Black man presented with 5 days of dysphagia, odynophagia, and rash. He said he had begun a course of trimethoprim-sulfamethoxazole 6 days prior for a presumed urinary tract infection. Owing to the cutaneous lesions and punch biopsy findings, he was diagnosed with drug-induced Stevens-Johnson syndrome. DISCUSSION: Stevens-Johnson syndrome is associated with a relatively high mortality rate. It is most commonly drug-induced and presents with extensive erythema, erosions, and blisters throughout the body. CONCLUSIONS: Stevens-Johnson syndrome is a rare and often life-threatening disease. Early diagnosis and management is important for delivering high-quality patient care.

Protein-Losing Enteropathy in Crohn's Disease: Two Unusual Cases.

Protein-losing enteropathy (PLE) occurs when protein losses throughout the gastrointestinal (GI) tract exceed the liver's ability to produce new protein. This is a rare presentation of Crohn's disease and few reported cases of PLE related to Crohn's exist in the literature. We describe two patients who presented with symptoms of PLE. After extensive diagnostic workup both were diagnosed with Crohn's disease and managed with prednisone.

Nonatherosclerotic Abdominal Vasculopathies.

BACKGROUND: Nonatherosclerotic abdominal arterial vasculopathies (NAVs), including mesenteric or renal artery dissection, aneurysm, stenosis, and vasculitis, are rare but have great clinical significance. Patients may present emergently with life-threatening complications such as arterial rupture and hemorrhagic shock. Herein, we present our center's experience with NAVs and provide extensive literature review to close the gap in the scarce, related literature. METHODS: From a single-center retrospective data analysis, we identified and characterized subjects (aged 18-60 years) who presented with NAV between January 2000 and December 2015. Of the 1416 charts reviewed, 118 met inclusion criteria. RESULTS: The average age of patients with NAV was 47.0 ± 9.9 years, mostly affecting women (64%). Primary diagnoses included fibromuscular dysplasia (FMD) (25.4%), isolated aneurysms (24.6%), and median arcuate ligament syndrome (MALS) (15.3%). Less common diagnoses were localized vasculitis of the gastrointestinal tract (LVGT) (7.6%), isolated dissection (5.1%), microscopic polyangiitis and granulomatosis with polyangiitis (5.1%), trauma (4.2%), segmental arterial mediolysis (4.2%), Ehlers-Danlos syndrome (2.5%), Takayasu's arteritis (2.5%), polyarteritis nodosa (1.7%), idiopathic abdominal aortitis (0.8%), and Loeys-Dietz syndrome (0.8%). Females constituted 90% of patients with FMD, 77.8% with MALS, 77.8% with isolated aneurysms, 66.7% with Takayasu arteritis, and 55.6% with LVGT. Prevalent comorbidities included tobacco use (43.6%) and hypertension (52.1%). Coil embolization was used in 14.4%, anticoagulation in 11.9%, angioplasty/stenting in 11.9%, open resection/surgical revascularization in 10.2%, and prednisone in 10.2% of the cases. Conservative management was pursued in 33.1% of the patients. A high degree of symptom relief was shown in 91.7%. CONCLUSIONS: NAV are rare and can be caused by different etiologies that primarily affect females. Hypertension and tobacco use were prevalent. Various imaging strategies revealed aneurysms, stenosis, dissection, and/or thrombosis affecting renal and celiac arteries. Most patients improved with conservative, medical, endovascular, or surgical approach. More research is needed to standardize management approach to patients with NAV.
