Necrotizing fasciitis: a fourteen-year retrospective study of 163 consecutive patients.
This review was prompted by continued public and professional interest of necrotizing fasciitis as well as worldwide increases in the incidence of streptococcal invasive infections. Our objective was to outline the clinical course of necrotizing fasciitis and delineate factors relating to mortality among 163 diagnosed patients. Over 14 years patients diagnosed with necrotizing fasciitis were reviewed for patient history, comorbid conditions, and progression of clinical course. ⋯ Mortality is correlated to patient history, comorbid conditions, and progression of clinical course. Necrotizing fasciitis can occur idiopathically and is generally a polymicrobial infection that sometimes occurs in the absence of streptococci. Clearly the mortality and morbidity associated with necrotizing fasciitis can be decreased with clinical awareness, early diagnosis, adequate surgical debridement, and intensive supportive care.

Renal transplantation remains a mainstay of therapy for end-stage renal disease. Cardiac disease has a high prevalence in this patient population. This study reviews the factors and outcomes associated with cardiac surgery in renal transplant recipients. ⋯ Standard cardiac surgery procedures can be performed with relative safety in patients with functioning renal allografts. The incidence of perioperative and late development of renal failure requiring dialysis is low. The long-term survival and symptomatic improvement achieved are favorable and warrant continued performance of cardiac surgery in patients with functioning renal allografts.

Comparative StudyPercutaneous dilatational tracheostomy is as safe as open tracheostomy.
Although percutaneous dilatational tracheostomy (PDT) has been advocated as an alternative to open tracheostomy (OT) its relative safety has been questioned repeatedly. This study prospectively compared the safety and complications of PDT and OT. Ninety-four patients underwent PDT and 252 patients underwent OT at this institution from December 1998 through April 2000 with the choice of procedure left to the operator. ⋯ Subcutaneous emphysema, soft-tissue infection, and a malpositioned tracheostomy tube were the remaining complications in the OT patients. We conclude that the complication rates of PDT and OT are comparable. The choice of PDT or OT should be dictated by the surgeon's training and experience, the patient's condition, neck anatomy, and stability for transfer to the operating room.

The abdominal compartment syndrome (ACS) is a clinical entity that develops after sustained and uncontrolled intra-abdominal hypertension. ACS has been demonstrated to affect multiple organ systems including the cardiovascular, respiratory, gastrointestinal, genitourinary, and neurologic systems. To date most descriptions of ACS are found in the trauma literature, but the development of ACS in the general surgical population is being increasingly observed. ⋯ Surgical decompression of ACS significantly reduces peak inspiratory pressure while increasing urine output and cardiac index. The observed association between ACS and ischemic bowel may result from decreased mucosal perfusion as a direct result of abdominal hypertension. In our patient population ACS resulted in a 61.1 per cent mortality.

The presenting chest roentgenogram in acute type A aortic dissection: a multidisciplinary study.
Acute type A aortic dissection requires early diagnosis and prompt surgical intervention. It is not entirely clear whether patients with this form of dissection have clear-cut chest roentgenogram (CXR) patterns or whether the CXR can guide the physician in directing further workup for acute aortic dissection. The purpose of this study is to evaluate the impact of the initial CXR in arousing suspicion for acute type A aortic dissection. ⋯ This data indicates that the presenting CXR is neither sensitive nor specific for acute type A dissection. In a patient with a suspicious history or physical examination, however, a CXR showing mediastinal widening or other aortic abnormalities should increase the suspicion for dissection and warrant further workup. Furthermore in a patient with a clinical suspicion a normal CXR reading should not delay echocardiography to rule out type A dissection.
