Neutropenic enterocolitis, sometimes called typhilitis, is the most common gastrointestinal infection related to neutropenia, but its rarity, confusing terminology, and protean, non-specific manifestations result in variable approaches to diagnosis and management. ⋯ Neutropenic enterocolitis is a heterogeneous diseazse state with the capacity to affect many areas of the gastrointestinal tract, and disease severity that ranges from mild to fatal. A high index of suspicion is needed for all patients who present with fever and abdominal pain in the setting of neutropenia. Early detection allows a majority of cases to resolve with nonoperative management and supportive care, but surgical intervention is mandatory for peritonitis, bowel perforation, or gastyrointestinal hemorrhage that persists despite correction of coagulopathy.

Obesity and site-specific nosocomial infection risk in the intensive care unit.
Obese patients are at higher than normal risk for postoperative infections such as pneumonia and surgical site infections, but the relation between obesity and infections acquired in the intensive care unit (ICU) is unclear. Our objective was to describe the relation between body mass index (BMI) and site-specific ICU-acquired infection risk in adults. ⋯ Obesity is an independent risk factor for ICU-acquired catheter and blood stream infections. This observation may be explained by the relative difficulty in obtaining venous access in these patients and the reluctance of providers to discontinue established venous catheters in the setting of infection signs or symptoms.

Randomized Controlled TrialManagement strategy for dirty abdominal incisions: primary or delayed primary closure? A randomized trial.
It is still a matter of debate whether delayed primary closure (DPC) of dirty abdominal incisions reduces surgical site infections (SSIs) compared with primary closure (PC). Our objective was to determine whether DPC of dirty abdominal incisions reduces SSIs. ⋯ Delayed primary closure is a sound incision management technique that should be utilized for dirty abdominal incisions. It significantly lowers the rate of superficial SSI as well as fascial dehiscence and reduces the mean CIH time and hospitalization. The short-term cosmetic appearance is superior.

Multicenter StudyHyperbaric oxygen does not improve outcome in patients with necrotizing soft tissue infection.
Patients with necrotizing soft tissue infections (NSTIs) require prompt surgical debridement, appropriate intravenous antibiotics, and intensive support. Despite aggressive treatment, their mortality and morbidity rates remain high. The benefit of hyperbaric oxygen (HBO) as an adjunctive treatment is controversial. We investigated the effect of HBO in treating NSTIs. ⋯ Adjunctive use of HBO to treat NSTIs did not reduce the mortality rate, number of debridements, hospital length of stay, or duration of antibiotic use. Immunosupression and early hypotension were important risk factors associated with higher mortality rates in patients with NSTIs.
