[Heat stroke with anuria, muscular disorders and early hypercalcemia].

A case is reported of heat stroke associating dehydration, anuria, muscle disorders and early hypercalcemia. All disorders disappeared within 48 hours with rehydration. Early hypercalcemia differs from late hypercalcemia reported at resumption of diuresis. Early hypercalcemia might result from blood concentration with hyperproteinemia and release of bone calcium under the action of PTH. Its prognosis is good, which is not the case of late hypercalcemia.

Adjuvant hyperthermic intraperitoneal peroperative chemotherapy (HIPEC) associated with curative surgery for locally advanced gastric carcinoma. An initial experience.

AIM OF THE STUDY: After macroscopic radical (R0) surgery for advanced gastric carcinoma, 40 to 50% of the tumors recur in the abdomen as locoregional or peritoneal disease. We initiated a protocol in which patients with suspicion of macroscopic serosal, lymphatic or peritoneal invasion, treated with R0 resection, underwent adjuvant HIPEC. METHODS: Between June 1998 and January 2003, 16 patients with locally advanced adenocarcinoma of the stomach were included in the study. Surgery consisted of a total gastrectomy with a D2 lymphadenectomy. Splenectomy (n = 1), splenopancreatectomy (n = 4), transverse colectomy (n = 3), left hepatectomy (n = 1), localized peritonectomy (n = 3) were associated to obtain a R0 resection. HIPEC protocol consisted of heated (42.5 degrees C) intraperitoneal mitomycin C (15 mg/m2) for a planned duration of 90 minutes. RESULTS: HIPEC median duration was limited to 73(20-90) min because of central hyperthermia recognition in half of the cases. One patient died in the postoperative period of sepsis secondary to a duodenal fistula. Postoperative morbidity included pancreatic fistula (n = 2), pulmonary oedema (n = 1), pulmonary embolus (n = 1) and transient renal failure (n = 1). UICC staging was IB (n = 2), II (n = 2), IIIA (n = 5), IIIB (n = 1), IV (n = 6). Nine of the 16 patients are alive without recurrence with a median follow-up of 52 months. Four patients developed a recurrence, intraperitoneal (n = 2), systemic (n = 1), or combined (n = 1). Two patients were lost to follow-up. CONCLUSIONS: Aggressive surgical therapy and HIPEC might represent the standard of care in a selected population with locoregional disease and for whom a R0 resection can be achieved. This protocol was associated in this study with a 75% 5-year survival with a low peritoneal recurrence rate and an acceptable morbidity.

Treatment of inflammatory bowel disease with azathioprine: how to use it in 1999.

Azathioprine and 6-mercaptopurine are effective drugs in the management of steroid dependent and chronic active inflammatory bowel diseases. They are also well tolerated on the long term. However, their use is still hampered by some drawbacks including delay before efficacy, 20-35% of non responders, relapse at withdrawal of the drugs, possible bone marrow toxicity and other side effects. During the last few years, these drawbacks have been challenged by important studies showing that a better knowledge of the metabolism of these drugs may help to improve their use.

Initial medical management of severe acute ulcerative colitis.

Severe colitis is life-threatening complication of ulcerative colitis. Early recognition of the severity of the colitis, intensive medical therapy and prompt surgery when necessary have all contributed to improved outcome. Initial medical treatment should be instituted as soon as the diagnosis is made with an intravenous corticosteroid associated with supportive treatment. If the patient fails to response to this intensive treatment after 5-7 days, cyclosporin should be initiated. If cyclosporin is not used then colectomy should be performed immediately. Moreover, significant deterioration at any point during medical therapy is an indication for colectomy. The gravity of the patient's condition require close interaction between physician an surgeon.

Genetics of Crohn's disease behaviour.

Crohn's disease is probably an heterogeneous entity. This heterogeneity may be linked to either genetics or environment. In particular the behaviour of the disease, i.e. the tendency to develop stricturing and/or penetrating lesions, may be linked to the genetic background. While epidemiological and clinical data suggest the relevance of these behavioural classifications, the progresses in the characterization of the immuno-inflammatory reaction in the bowel wall shed a new light on possible candidate genes for these genetic predispositions to various Crohn's disease behaviours. Association studies an linkage analysis focusing on growth factors, metalloproteinases and their tissue inhibitors as well as cytokines may bring new interesting data in this field.

Observational survey of NSAID-related upper gastro-intestinal adverse events in Belgium.

OBJECTIVES: To evaluate the impact of NSAID use on current routine upper GI endoscopy (UGIE) and to compare the lesions found in NSAID users and non-users. METHODS: Participating gastroenterologists consecutively documented outpatients with and without suspicion of bleeding, referred for upper gastrointestinal endoscopy. Patient characteristics, presence of risk factors, NSAID use and endoscopic findings were reported on standard data collection forms. MAIN RESULTS: A total of 2685 non-bleeding and 159 bleeding patients were enrolled within a time period of 2 months. NSAID therapy was present in 20% of the non-bleeding patients and at least 9% of referrals for endoscopy were directly related to suspected NSAID adverse events. Nearly half of acute bleeding patients (42%) were NSAID users, including aspirin for cardioprevention. Warning digestive symptoms prior to acute bleeding were frequently absent (56%). Oesophagitis was the main endoscopic diagnosis (51% of patients). Gastroduodenal (GD) ulcer was significantly more frequent in NSAID users, whereas oesophagitis and bleeding oesophageal varices were more frequent among non-users. Analysis of odds ratio's demonstrated NSAID use to significantly increase the risk for gastric ulcer in the whole patient group (OR = 2.73; 95% confidence interval (CI): 1.98-3.77; p < 0.001) and, in addition, for duodenal ulcer in the elderly (> 65 y) subgroup (OR = 2.91; 95% CI: 1.52-5.59; p < 0.05). CONCLUSIONS: This survey confirms the high incidence of GD ulcers in NSAID users and the risk for serious gastrointestinal complications, often occurring without warning symptoms. It underlines the impact of NSAID use on the routine endoscopy load, the necessity of careful selection of patients for NSAID prescriptions and the need for gastropreventive measures, particularly in elderly patients and patients associating multiple risk factors.

Pregnancy and inflammatory bowel disease.

Overall, around 25% of women with inflammatory bowel disease will conceive during their disease. Most of the women with inflammatory bowel disease will have a normal pregnancy and healthy children. However, specific problems may arise related to these pregnancies. This paper reviews what is known on fertility, risk of disease transmission, effect of the disease on the pregnancy and the reverse, delivery, medical follow up and treatment as well as breastfeeding in the setting of inflammatory bowel disease.

Treatment of acute diarrhoea: update of guidelines based on a critical interuniversity assessment of medications and current practices.

Further to a thorough analysis of the problem of acute diarrhoea and the therapeutic options, recommendations were defined following a multidisciplinary approach. These guidelines take into account the reality of frequent self-medication. They further differ as a function of age (children, primarily treated by ORS and for whom self-medication is not advised versus adults who can self-medicate), symptoms (uncomplicated diarrhoea versus dysentery) and location where the diarrhoea is contracted (at home or when travelling).

Chronic ischaemic gastritis: an unusual form of splanchnic vascular insufficiency.

Three cases of erosive gastroduodenitis secondary to chronic splanchnic vascular insufficiency are reported. In all cases, pain failed to respond to conventional therapeutic measures for peptic ulcer disease. A patchy discolouration and erythematous mottling of the gastric mucosa, with scattered shallow aphthous ulcers, was seen on endoscopic examination. Angiography showed coeliac axis involvement in all patients, with insufficient mesenteric collateral pathways. Chronic gastritis resolved clinically and endoscopically after revascularization.
