A 25-year-old Syrian presented complaining mainly of fever, night sweats and nausea. He had 3 days earlier mild abdominal cramps and short-lived diarrhoea. On admission, he developed signs of deep vein thrombosis and blood and stool cultures showed Salmonella enteriditis infection. The patient was started on chloramphenicol and later showed acute abdominal signs. Laparotomy revealed intestinal perforation on the lower ileum. The case together with the experience in this hospital and elsewhere of Salmonella enteriditis infections are discussed, showing that two complications shown in this case are common for Salmonella typhi and paratyphi infections but are unusual for other Salmonella infections.

It is known that ethylestrenol and/or phenformin can normalize deficient fibrinolysis in the vessel walls and prevent recurrent thromboembolism (Hedner et al., 1976; Nilsson et al., 1975, 1981). Because of the side-effects of phenformin, we studied the effect of a phenformin-like substance: moroxydine chloride (Kabi 1886), which unlike phenformin, does not cause lactic acidosis. A prospective randomized clinical trial was carried out on 49 patients with a decreased release capacity of fibrinolytic activity (venous occlusion test for 20 min as described by Robertson et al. (1972) on at least two occasions. They received either moroxydine chloride in a dose of 0.04 g/kg a day or no specific treatment. Most of the patients had earlier at least one episode of deep venous thrombosis. At review 6 months after entering the trial, it was found that out of 26 patients receiving moroxydine chloride, the release capacity was normal in 16 (62%), compared with 5 (22%) of the 23 controls. Dicoumarol alone did not seem to have any effect on the fibrinolysis. The only side-effects were occasional diarrhea in two, which was controlled by reduction of the dose, and itching requiring withdrawal of the drug in one. Moroxydine chloride, thus, seems to normalize a defective release capacity of vessel wall in a fair percentage of cases.

Anti-phospholipid syndrome, originally called anticardiolipin syndrome, is characterized by the presence of anti-phospholipid antibodies and a marked tendency to both arterial and venous thrombosis. The little information available on the implications of this syndrome for anesthesia derive from the recent description of the disease. We describe 2 patients, each with 1 of the 2 forms of antiphospholipid syndrome that have been described to date, and each needing surgery for a different reason. The first was a 24-year-old woman who was admitted to the hospital with diarrhea, fever and metrorrhagia in her fifth month of pregnancy. Blood tests revealed a weakly positive title of anti-cardiolipin antibodies. Steroid and antiplatelet therapy was begun. Delivery was at 35 weeks by elective cesarean with epidural anesthesia due to oligoamnios. The second patient was 52-year-old woman with a history of 13 miscarriages, cerebrovascular accident and deep venous thrombosis. She had been diagnosed as having systemic lupus erythematosus with anti-phospholipid syndrome and was receiving corticoid and antiplatelet therapy. She had been admitted on 2 occasions for epistaxis, purpura in the lower extremities and severe thrombocytopenia. The last condition did not respond well to immunosuppressant therapy and a splenectomy was therefore performed with the patient under general anesthesia. In both cases recovery was good in spite of the serious complications of anesthetic management.

In a phase I trial, 17 patients were treated with 5-fluorouracil (5-FU) 500 mg/m2 and leucovorin (LV) 500 mg/m2 intravenously weekly for 6 weeks followed by 2 weeks' rest and interferon alfa-2b 1, 3, 5, 8, or 10 million units (MU) subcutaneously tiw with no rest period. The most common toxicities were fatigue (12), diarrhea (10), nausea/vomiting (7), and fever (7). The maximum tolerated interferon dose was 8 MU tiw. Fatigue and increased incidence of other toxicities rather than a single dose-limiting toxicity occurred at the next highest interferon level. ECOG grade III/IV toxicity occurred in 5 patients and included transient supraventricular tachycardia and brief seizure episode (1), dyspnea (1), decreased performance status (1), anemia requiring transfusion (1), and deep vein thrombosis (1). No toxic deaths occurred. Two patients with non-small cell lung cancer (NSCLC) had partial responses lasting 5 and 4 months. Two other patients with NSCLC had either minor response or stable disease, and 1 patient with colon cancer had a significant decline in serum CEA. The recommended alpha interferon dose is 8 MU tiw when given with this schedule of 5-FU/LV.

Azathioprine is a drug commonly used for the treatment of inflammatory bowel disease, organ transplantation and various autoimmune diseases. Hepatotoxicity is a rare, but important complication of this drug. The cases reported to date can be grouped into three syndromes: hypersensitivity; idiosyncratic cholestatic reaction; and presumed endothelial cell injury with resultant raised portal pressures, venoocclusive disease or peliosis hepatis. The components of azathioprine, 6-mercaptopurine and the imidazole group, may play different roles in the pathogenesis of hepatotoxicity. The strong association with male sex, and perhaps with human leukocyte antigen type, suggests a genetic predisposition of unknown type. Many of the symptoms of hepatotoxicity, such as nausea, abdominal pain and diarrhea, can be nonspecific and can be confused with a flare-up of inflammatory bowel disease. As well, the subtype resulting in portal hypertension can occur without biochemical abnormalities. A 63-year-old man with Crohn's disease who is presented developed the rare idiosyncratic form of azathioprine hepatotoxicity, but also had a severe disabling steroid myopathy, peripheral neuropathy, resultant deep venous thrombosis and pulmonary embolism related to immobility, and a nosocomial pneumonia. His jaundice and liver enzyme levels improved markedly on withdrawal of the drug, returning to almost normal in five weeks. Treating inflammatory bowel disease effectively while trying to limit iatrogenic disease is a continuous struggle. Understanding the risks of treatment is the first important step. There must be a low threshold for obtaining liver function tests, especially in men, and alertness to the need to discontinue the drug or perform a liver biopsy should patients on azathioprine develop liver biochemical abnormalities, unexplained hepatomegaly or signs of portal hypertension.

METHODS: Evaluated are surgical difficulties, management problems and weight loss in patients with distal gastric bypass as a revisionary procedure. Eighty patients were followed up to 3 years; four were lost to follow-up. Mean age was 43; mean prebariatric surgery weight 134 kg; height 1.65 meters; body mass index 40.1; ideal body weight 62.7 kg; excess weight 70.5 kg; per cent excess weight 214%. A 250 cm stomach-to-ileocecal valve segment of small bowel was used, and the biliopancreatic secretions were brought into the terminal ileum 100 6 in from the ileocecal valve. Mean pouch size was 63 cc; length of hospital stay 5 days; operative blood loss 616 cc; operative time 130 min. RESULTS: Intraoperative complications included three splenic injuries (without splenectomy). Early complications included one deep vein thrombosis, two marginal ulcers, one GI hemorrhage, one wound dehiscence, one pouch outlet obstruction and one pancreatitis. Late complications included: one death from protein malnutrition/ ARDS; 21 hypoproteinemia; six protein malnutrition, and of these, three had hyperalimentation; three cholecystitis; 27 anemia; 22 incisional hernia; two staple-line disruption (reoperated); 26 low serum iron; 11 prolonged (>6 months) diarrhea; three prolonged frequent vomiting; and two unrelated deaths (chronic myelogenous leukemia and amyotrophic lateral sclerosis). Mean excess weight loss was 83% at 12 months; 89% at 24 months; and 94% at 36 months. CONCLUSION: The distal gastric bypass is fraught with the operative and immediate post-operative complications experienced in any revisionary bariatric surgery. Distal gastric bypass is very effective in producing long-term weight loss. Nutritional problems are common but usually easily corrected. The most serious nutritional complication is protein malnutrition, which must be identified and corrected early. Success of this procedure is dependent upon patient compliance with proper nutrition and supplements, and regular office follow-up with monitoring of laboratory data. Patients who are noncompliant are at significant risk for complications.

XR 5000 is one of a series of tricyclic carboxamide-based cytotoxic agents. It binds to DNA by intercalation and stimulates DNA cleavage by inhibition of both topoisomerase I and II, thus possibly overcoming the resistance resulting from downregulation of either enzyme. Twenty patients with advanced or metastatic colorectal cancer, unpretreated for metastatic disease, received XR 5000 at the dose of 3010 mg/m(2) in a 120-h central intravenous (i.v.) infusion every 3 weeks. Response was evaluated every two cycles. No complete (CR) or partial responses (PR) were observed in eligible patients (response rate, 0 of 19, 0%; 95% confidence interval (CI): 0-18%). 5 patients had stable disease, which lasted from 79 to 157 days. Haematological toxicity was low, since only one grade 4 neutropenia and two grade 3 anaemia were observed. Other treatment-related grade 3-4 toxicities were: deep venous thrombosis (2 cases), liver toxicity, diarrhoea, anorexia, dyspnoea, chest pain, infection (1 case each). Despite the good toxicity profile, these results do not support further trials with XR 5000 in metastatic colorectal cancer.

The association between long haul travel and the risk of venous thromboembolism are suspected for long time. Mostly air travel related thrombosis series have been reported in the literature. Risk factors can be classified as: 1. travel related factors (coach position, immobilization, prolonged air travel, narrow seat and room, diuretic effect of alcohol, insufficient fluid intake, dehydration, direct pressure on leg veins, rare inspiration). 2. air plane related risk factors (low humidity, relative hypoxia, stress). 3. patient related factors (hereditary and acquired thrombophylia, previous deep venous thrombosis, age over 40, recent surgery or trauma, gravidity, puerperium, oestrogen containing pills, varicosity, chronic heart disease, obesity, fever, diarrhoea, vomiting, smoking). No patient related factors were found in some cases. To reduce the hazards air travellers are rightly concerned to know the level of the risk and the airlines should be responsible for this information. People should discuss with their physician what prophlylactic measures should be taken, such as compression stockings or low molecular weight heparin. Not only flight but car, bus and train travellers are also at risk of developing venous thromboembolism. Long haul travel alone is a separate risk factor for venous thromboembolism.

A 61-year-old man received reduced intensity stem cell transplantation (RIST) for the treatment of metastatic gastric cancer. The cytoreductive course of RIST was uneventful until day 0, when fever suddenly developed and his performance status deteriorated. Edema developed in the bilateral lower extremities by day 7, which was diagnosed by Doppler ultrasonography as deep vein thrombosis (DVT) involving the femoral veins to the inferior vena cava. While the edema improved with anticoagulation treatment, gastrointestinal graft-versus-host disease (GVHD) followed on day 13. Diarrhea subsided spontaneously, but hypoalbuminemia persisted, with the subsequent development of oliguria and jaundice on day 18. He died of sepsis on day 30, without any evidence of cancer progression. This case demonstrates that DVT is a potentially significant problem following RIST for solid tumors.

An older female underwent bariatric surgery which was followed by a significant weight loss and diarrhea, from which C. difficile was isolated just before her hospitalization. Less than 48 hours after admission, she became febrile, developed deep venous thrombosis of the leg and a pulmonary embolus. Blood cultures grew out Streptococcus pneumoniae and the patient developed purpura fulminans. There was convincing laboratory evidence for disseminated intravascular coagulation and a marked depletion of proteins C and S as well as antithrombin. Treatment with ceftriaxone and drotrecogin alfa together with parenteral nutrition led to disappearance of the pathogen and ultimate normalization of the anticoagulant factors. We believe that malabsorption of vitamin K dependent proteins C, S and antithrombin due to bariatric surgery predisposed the patient to purpura fulminans and disseminated intravascular coagulation.
