Mesenteric infarction: an analysis of 83 patients with prognostic studies in 44 cases undergoing a massive small-bowel resection.

A series is presented of 83 patients surgically explored for massive bowel infarction. Old men with previous heart disease and symptoms of peripheral atherosclerosis were primarily affected. Clinical presenting features were abdominal pain (100 per cent), peritonitis (57 per cent), shock (34 per cent) and hypothermia (26 per cent). A third-space syndrome with metabolic acidosis and uraemia was the most common physiological derangement. Age was the only factor that appeared to have influenced the surgeon's decision to perform massive bowel resection (71 years in non-resected versus 64 years in resected patients, P less than 0.006). The overall mortality rate was 71 per cent. Forty-four patients underwent massive bowel resection (mean length of remaining small bowel 60 +/- 40 cm) and twenty-four (54 per cent) survived the procedure. Axillary temperature was higher in survivors (36.7 degrees C versus 36.1 degrees C, P less than 0.03). Early postoperative total plasma protein and albumin concentrations were also higher in survivors (57 versus 46 g/l, P less than 0.005; 27 versus 22 g/l, P less than 0.02). Patients with previous symptoms of atherosclerotic disease and high pre-operative blood urea levels also had a bad prognosis. Survivors had a mean hospital stay of 57 days and parenteral nutrition had to be maintained for a mean of 34 days. The survival rate achieved with massive resection justifies this surgical approach in selected patients with massive bowel infarction.

An evaluation of the efficacy of netobimin against Dicrocoelium dendriticum in sheep.

A trial was carried out to assess the efficacy of a nitrophenylguanidine compound, netobimin against Dicrocoelium dendriticum in naturally infected sheep. At a dose rate of 20 mg/kg bodyweight administered orally the drug was highly effective, producing a mean reduction of 98.9 per cent in the fluke burdens of treated animals compared with untreated controls. No side effects were observed in the treated sheep.

Surgical wound infections: prospective study of 4,468 clean wounds.

A prospective four-year study on the infection rate of clean operative wounds is presented. From January 1982 to June 1985, a nurse epidemiologist and a medical team assessed 4,468 operative procedures, from the day of surgery to the patients' discharge from the hospital. The infection rate was 3.2%. A higher incidence of wound infection was detected in patients requiring emergency operations (5.1%), in drained wounds (5.4%), and in patients with conditions thought to predispose to infection, such as advanced cancer, hepatic cirrhosis, diabetes, nephrotic syndrome, previous splenectomy, and treatment with immunosuppressive drugs (7.8%). Age over 65 did not influence infection rates. There were up to tenfold differences in infection indices between surgeons performing the same clean procedures. The continued monitoring of clean wound infection rates allowed the early detection and control of infection outbreaks. Providing periodic information on infection rates to the different surgical services was associated with decreasing infection rates over time.

Efficacy and safety of imipenem/cilastatin in the empirical treatment of septicemia.

The clinical efficacy and safety of imipenem/cilastatin in the empirical treatment of adult non-immunocompromised patients with severe bacterial septicemia was studied in a prospective and open trial. The dosage of imipenem/cilastatin was 500 mg q 6 h. Of 58 patients included, 41 were evaluable for efficacy. In those patients, 35 had chronic underlying diseases and the foci of bacteremia were identified in 37; the most common ones being cardiovascular, urologic or intraabdominal infections. All isolated organisms were sensitive to imipenem with an MIC for 90% of the strains of 1 mg/l. Imipenem/cilastatin treatment resulted in rapid control of the infections in 39 of the 41 evaluable patients (95.5%). In the remaining two patients treatment had to be prematurely discontinued due to adverse effects. The causative bacterial strains were eradicated from blood in all patients who received more than one day of imipenem/cilastatin treatment but persisted sensitive to imipenem in peripheral foci in five patients (17%). Clinical and laboratory adverse reactions were noted in seven patients. In conclusion, imipenem/cilastatin was a well tolerated and effective empirical drug for treatment of septicemia.

Aliphatic nitro compounds in Astragalus lusitanicus Lam.

Astragalus lusitanicus Lam lusitanicus has been reported to be toxic for mammals. Annually, many sheep are poisoned and die because of feeding on this legume. Aliphatic nitro compounds were detected using two different methods. Colormetry with Griess-ilosvay reagent showed that nitro-compounds occurred in frozen plant samples. Two different compounds in aqueous extract and 1 or 2 in methanolic extracts were detected by thin-layer chromatography. Nitro compounds concentrations were similar to those reported in toxic species of North American Astragalus.
