Role of early and extensive surgery in the treatment of severe necrotizing soft tissue infection.

Forty-two patients with necrotizing soft tissue infection are reviewed. Bacterial culture revealed between two and seven types of micro-organism in each patient. All patients were treated with radical surgical debridement and a combination of antibiotics. In 30 patients, early diagnosis and treatment resulted in only two deaths. Delayed surgical intervention in 12 patients transferred from outside hospitals was followed by nine deaths. Predisposing factors and site of infection did not affect outcome. Of 26 patients with systemic manifestations of sepsis, 16 survivors responded well to initial surgical debridement.

Radionuclide visualization of acute occlusive and nonocclusive intestinal ischemia.

A noninvasive radionuclide technique to visualize ischemic small intestine was evaluated. Vascular ligation of 20-30 cm ileum was done in rabbits. After induction of ischemia, technetium (99mTc) methylene diphosphonate (TMDP) was injected IV at intervals up to 24 hours. Images were recorded 1 and 3 hours after injection of radioisotope and showed preferential (9:1) uptake by ischemic bowel. Positive scans were present in all animals up to 4 hours and in 75% at 10-12 hours, but in none 24 hours after induction of ischemia. Nonocclusive intestinal ischemia was simulated in 4 dogs by infusing norepinephrine into a jejunal mesenteric arterial branch. After 1 hour, an IV bolus of TMDP was injected and images recorded at intervals up to 3 hours. Selective uptake of isotope by the ischemic segment was observed in all animals. Angiography confirmed that isotope uptake was confined to the infused segment. These studies show that occlusive intestinal ischemia can be detected, by radionuclide imaging up to 12 hours, and nonocclusive (low flow) ischemia for at least 4 hours, after onset.

Acute appendicitis complicating pregnancy.

Seventeen cases of acute appendicitis complicating pregnancy were analysed. The presenting symptoms were abdominal pain, nausea and anorexia. The usual physical findings were direct abdominal tenderness and rectal tenderness. Correct diagnosis was more difficult when gestation was advanced. This was reflected both by the severity of the disease process found at operation and by the increasing foetal mortality rate. Delay in diagnosis and treatment is the main factor causing high maternal and foetal death rates, especially when pregnancy is advanced.

CT characterization of multivesicular hydatid cysts.

One hundred seventy-eight abdominal multivesicular hydatid cysts were classified into three types (A, B, C) based on CT densities and morphology of cysts. The CT density of viable daughter cysts was always appreciably lower than those of mother hydatid cysts. This density differential between mother and daughter hydatid cyst fluid is a useful diagnostic sign.
