Review Comparative Study[Current treatment strategy in malignant pleural effusion].
Malignant pleural effusions are a grave consequence of advanced cancer disease. The successful suppression of pleural fluid reaccumulation can make a major contribution to the management and palliative care of patients with disseminated cancer. Many treatment concepts have been reported in the literature. ⋯ Talc was superior to other agents in 6 of 6, Corynebacterium parvum in 3 of 4 and bleomycin or tetracycline only in 3 of 8 studies. Adverse effects were frequently observed with cytostatic agents, but were very rare in the case of talc or fibrin instillation. Comparing the recently published data pleurodesis with talc appears to be the most effective treatment strategy, followed by Corynebacterium parvum, bleomycin and tetracycline.

Review[The value of adjuvant and neoadjuvant chemotherapy in treatment of stomach carcinoma].
The incidence of gastric adenocarcinoma has decreased dramatically in most Western countries over the past five decades. However, the five-year survival rate remains poor and late diagnosis is one of the main reasons for the lack of marked improvement in outcome. More than 50% of the patients found to have advanced local (stage T III), or systemic (stage T IV) gastric cancer at the time of diagnosis. ⋯ The efficacy of neoadjuvant chemotherapy in potentially resectable gastric carcinoma cannot be definitely assessed at the present time since only scant, preliminary findings are available. Future goals for the treatment of gastric carcinoma should include studies evaluating preoperative chemotherapy using effective, but less toxic substances, based on exact tumor-staging by means of endoluminal sonography. Furthermore, research projects investigating the value of intraperitoneal therapeutic regimens such as hyperthermic chemoperfusion or intraperitoneal instillation of the requisite substances in the prevention of intraperitoneal carcinomatosis and local recurrence will be of great importance.

Review[Glutamine: effects on the immune system, protein balance and intestinal functions].
Glutamine is the most abundant free amino acid of the human body. In catabolic stress situations such as after operations, trauma and during sepsis the enhanced transport of glutamine to splanchnic organs and to blood cells results in an intracellular depletion of glutamine in skeletal muscle. Glutamine is an important metabolic substrate for cells cultivated under in vitro conditions and is a precursor for purines, pyrimidines and phospholipids. ⋯ Moreover, glutamine exerted a trophic effect on the intestinal mucosa, decreased the intestinal permeability and thus may prevent the translocation of bacteria. In conclusion, glutamine is an important metabolic substrate of rapidly proliferating cells, influences the cellular hydration state and has multiple effects on the immune system, on intestinal function and on protein metabolism. In several disease states glutamine may consequently, become an indispensable nutrient, which should be provided exogenously during artificial nutrition.

During the past years perinatal mortality in diabetic pregnancy has been lowered significantly, in special collections with highly motivated diabetic women even below 2%. In case of optimal metabolic control and absence of diabetic angiopathy the perinatal survival rate is identical to that in normal pregnancy. But adequate metabolic control cannot be reached in all pregnant women during the whole period of gestation, and pre-existing diabetic angiopathy exists frequently; therefore diabetic pregnancy will be associated with elevated perinatal mortality and morbidity also in the future. ⋯ Diabetic women with macroangiopathy, especially with coronary artery disease show a high risk for cardiovascular events during pregnancy. The occurrence of acute myocardial infarction in pregnant diabetic women is associated with elevated fetal and maternal mortality. Though there are case reports in the literature describing a successful fetal and maternal outcome after myocardial infarction during pregnancy.
