[Sports and pregnancy].

Pregnant women consult often their obstetricians for counselling about their way of living. Particularly answering questions concerning physical activity and sports during pregnancy require a profound knowledge on the physiological adaptations of pregnancy and, on the other hand, on performance and sports physiology. On the basis of the current state of research, physical exercise and sport are to be recommended during pregnancy so long as women are aware of potential dangers and contraindications. Maternal benefits and fetal benefits have today been demonstrated.

[HELLP syndrome].

The HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelet count) is a clinical expression of a multilayered disease whose central pathophysiology is abnormal placentation. Clinical research aims logically to search for new predictive and specific markers for the early identification of pregnant women at risk of developing a HELLP syndrome, the most common cause of feto-maternal mortality and morbidity.

Absorption of elemental and complex nutritional solutions during a continuous jejunal perfusion in man.

The jejunal absorption of either an elemental solution (amino acids, glucose and glucose oligosaccharides), or of nonelemental diet (chicken meat, egg-yolk power, soya flour, glucose, saccharose, maltose and dextrin maltose, corn and wheat oils) were compared in 25 healthy subjects by the technique of intestinal perfusion with a three-lumen tube. The test solutions were perfused just beyond the ligament of Treitz. The samples were collected 35, 70 and 105 cm below the infusion point. In a small segment of jejunum, the absorption increased the nutritional imbalance of the element diet 1 m below the infusion point, the flow rate in the lumen was similar for the two solutions and higher than the initial flow rate; the absorption, in terms of calories, is similar for the two solutions.

Fluid secretion in the duodenum and intestinal handling of water and electrolytes in Zollinger-Ellison syndrome.

The slow marker perfusion technique was used in five patients with the Zollinger-Ellison syndrome in order to determine the basal and postcibal flow rates of fluids passing the duodenojejunal junction and distal ileum, and the composition of those fluids. Fecal water and electrolyte excretions were also measured. The 24-hr outputs at the ligament of Treitz were markedly increased, while fecal losses were normal or only slightly increased. Thus, the overall intestinal reabsorption of water was 96%. Fasting rates of fluid and electrolyte flow at the ligament of Treitz were also measured during a basal period, followed by a period of continuous gastric aspiration. Removal of gastric secretion had the following effects on the fluid passing through the duodenum: (1) dramatic decrease in flow rate; (2) an increase in osmolality, from hypotonicity to isotonicity; (3) rise of pH, from acid to alkaline values; (4) a decrease of PCO2, from high to normal values. No increase in fasting plasma levels of immunoreactive secretin and motilin was observed in Zollinger-Ellison syndrome, whereas normal subjects respond to acid in the duodenum by a marked rise in the circulating levels of these hormones. These facts suggest that, in Zollinger-Ellison syndrome: (1) the ability of the small bowel and colon to reabsorb water and electrolytes is normal: (2) duodenal dissipation of hydrogen ions is mainly due to intraluminal neutralization by bicarbonate; and (3) stimulation of water and electrolyte secretion by the pancreas is inadequate.

[Ulcer of the colon and Mallory-Weiss syndrome (author's transl)].

A 71 year old man presents with a high and low hemorrhage with no signs of associated shock. Endoscopy shows a laceration of the cardia (Mallory-Weiss syndrome). The low hemorrhage is attributed to a left colic lesion that appears to be an ischemic colitis. Colonoscopy in addition to baryum enema is useful in the differential diagnosis of colon lesions.
