RESUMO
OBJECTIVE: Pheochromocytomas (PHs) and sympathetic paragangliomas (PGs) are tumors that produce catecholamines, predisposing patients to cardiovascular disease and gastrointestinal effects such as constipation. OBJECTIVES: i) determine the prevalence of constipation, its risk factors, and its impact on survival; ii) identify whether a systematic combination of fiber, water, and laxatives was effective for treatment of constipation. DESIGN AND METHODS: We retrospectively studied 396 patients with PH/PG diagnosed in 2005-2014. The study population was patients with constipation as a presenting symptom; the control group was patients without constipation as a presenting symptom. The MD Anderson Symptom Inventory was used to assess constipation and quality of life. RESULTS: Twenty-three patients (6%) had constipation. Constipation was associated with headaches, palpitations, diaphoresis, weight loss, and excessive noradrenaline production (P<0.0001). Eighteen of these patients had non-metastatic primary tumors larger than 5 cm and/or extensive metastases. No statistically significant differences in age, sex, and genotype were noted between the study and control groups. In patients without metastases, resection of the primary tumor led to symptom disappearance. A systematic combination of fiber, water, and laxatives was associated with symptom improvement. Two patients who presented unmanaged constipation died because of sepsis from toxic megacolon. CONCLUSIONS: Constipation is a rare and potentially lethal complication in patients with PH/PGs. Severe constipation can be prevented by recognizing and treating mild symptoms.

Ulcerative colitis is a chronic inflammatory disease of the colon; as many as 25% of patients with this disease require hospitalization. The goals of hospitalization are to assess disease severity, exclude infection, administer rapidly acting and highly effective medication regimens, and determine response. During hospitalization, patients should be given venous thromboembolism prophylaxis and monitored for the development of toxic megacolon. Patients who do not respond to intravenous corticosteroids should be considered for rescue therapy with infliximab or cyclosporine. Patients who are refractory to medical therapies or who develop toxic megacolon should be evaluated promptly for colectomy. Patients who do respond to medical therapies should be discharged on an appropriate maintenance regimen when they meet discharge criteria. We review practical evidence-based management principles and propose a day-by-day algorithm for managing patients hospitalized for ulcerative colitis.

Clostridium difficile-associated diarrhea (CDAD) is the most common etiologically-defined cause of hospital-acquired diarrhea. Caused by the toxins of certain strains of C difficile, CDAD represents a growing concern, with epidemic outbreaks in some hospitals where very aggressive and difficult-to-treat strains have recently been found. Incidence of CDAD varies ordinarily between 1 to 10 in every 1,000 admissions. Evidence shows that CDAD increases morbidity, length of stay, and costs. This article described the clinical manifestations of CDAD, related risk factors, considerations for confirming CDAD, antimicrobial and non-antimicrobial treatment of CDAD, and issues related to relapses. The article concludes with a discussion of recent epidemic outbreaks involving CDAD.
