Morbid obesity results in a restrictive pulmonary syndrome including decreased functional residual capacity. General anaesthesia further decreases functional residual capacity, and consequently alters gas exchanges more profoundly in morbidly obese patients than in nonobese patients. Moreover, these changes persist longer during the postoperative period, rendering obese subjects vulnerable to postoperative respiratory complications. In this review, we present postoperative measures improving respiratory function of these patients. Whether these measures affect outcome remains however unknown. Patients suffering from obstructive sleep apnoea syndrome deserve special considerations that are briefly described. Finally, the algorithm of the postoperative respiratory management of morbid obese patients used in our institution is provided. [less ▲]

In this prospective study, we have compared women undergoing laparoscopic cholecystectomy, laparoscopic gynaecological surgery and laparoscopic minor gynaecological procedures (diagnostic, tubal, ligation) (n = 10 in each group) to determine if lower abdominal laparoscopy results in less postoperative pulmonary dysfunction than upper abdominal laparoscopy. Pulmonary testing was performed before operation, and 3 and 6 h after operation, on the first and second days after surgery. After operation, a significant reduction in forced vital capacity, forced expiratory volume in 1 s and peak expiratory flow rate occurred after laparoscopic cholecystectomy at each time. There were no significant changes after minor gynaecologic laparoscopy, whereas laparoscopic gynaecological surgery resulted in minor pulmonary dysfunction on the day of surgery only. We conclude that postoperative pulmonary function was less impaired after gynaecological laparoscopy than after laparoscopic cholecystectomy. This study suggests that the site of surgery is an important determinant of lung dysfunction after laparoscopy. [less ▲]

Metabolism in man is regulated by complex hormonal signals and substrate interactions, and for many years the clinical focus has centred on the metabolic and hormonal picture after an overnight fast. More recently, the postprandial state, i.e. 'the period that comprises and follows a meal', has received more attention. The oral glucose tolerance test (OGTT), although highly non-physiological, has been used largely as a model of the postprandial state. Epidemiological studies have shown that, when 'impaired', oral glucose tolerance is associated with an increased risk of cardiovascular disease. Postprandial hyperlipidaemia has been investigated more recently in epidemiological, mechanistical and intervention studies, most of which indicate that high postprandial triglyceride levels, and particularly postprandial rich triglyceride remnants, constitute an increased risk for cardiovascular disease. Recent studies have shown that excessive postprandial glucose excursions are accompanied by oxidative stress and, less well known, activation of blood coagulation (increase in circulating D-dimers and prothrombin fragments). The mechanisms through which increased postprandial glucose levels and lipid concentrations may damage endothelial cells on blood vessel walls appear to be complex. These mechanisms include the activation of protein kinase C, increased expression of adhesion molecules, increased adhesion and uptake of leucocytes, increased production of proliferative substances such as endothelin, increased proliferation of endothelial cells, increased synthesis of collagen IV and fibronectin, and decreased production of nitric oxide (NO). In conclusion, the 'postprandial state' cumulatively covers almost half of the nycthemeral period, and its physiology involves numerous finely regulated motor, secretory, hormonal and metabolic events. Epidemiological and mechanistical studies have suggested that perturbations of the postprandial state are involved in cardiovascular disease. Correcting the abnormalities of the postprandial state must form part of the strategy for the prevention and management of cardiovascular diseases, particularly those that are associated with diabetes mellitus.

te hypercalcemia (4.03 mmol/l) developed in a 50 years old woman after head and intraabdominal trauma (and splenectomy). After failure to correct the calcium levels by intravenous saline, furosemide, steroids and calcitonin, two hemodialyses were performed; definitive control of hypercalcemia was obtained by intravenous (3-amino-1-hydroxypropylidene)-1.1-bisphosphonic acid (APD). APD is a new drug analog of pyrophosphate; its main property is to block bone resorption, irrespective of its stimulus. As suspected by clinical and laboratory data and confirmed by arteriographic findings, surgery and pathologic examination, the underlying pathology was a mild primary hyperparathyroidism which was acutely worsened (parathyroid crisis) in the course of the trauma. Definitive treatment consisted of the removal of the adenoma responsible of the hyperparathyroidism. [less ▲]

Male rats were neonatally treated with cholesterol or a substance that blocks the aromatization of testosterone to estradiol (1,4,6-androstatriene-3,17-dione: ATD). At weaning (21 days) they were either housed alone or in small groups (2-3 animals) and tested for partner preference behavior (PPB) in adulthood. Choice was between an estrous female and an active male (Part I) and between an estrous female and an ATD-male (Part II). Tests were carried out in a 3-compartment box. Social isolation did not have major effects on PPB except when sexual interaction with the stimulus animals was prevented (Part I). In this case, isolates (ATD and control) showed higher preference scores (PS) for the estrous female and spent less time in the empty middle compartment. When the choice was between an estrous female and an ATD-male, partner PS decreased in all males, most clearly in ATD-males. The latter animals spent more time with the stimulus ATD-male than they had done in previous PPB tests with the normal stimulus male. In contrast to partner preference behaviors, sexual behavior was clearly affected by social isolation. Isolates (ATD and control) displayed lower frequencies of mounts and intromissions. These effects persisted over consecutive tests. Ejaculation was not affected. In conclusion, the present results confirm earlier findings about the significance of neonatal endocrine conditions for the organization of adult PPB in male rats. The presence or absence of social conspecifics after weaning appears to have little influence on adult PPB. [less ▲]

POTAMON is a unidimensional, non-stationary model, designed for simulating potamoplankton from source to mouth. The forcing variables are discharge, river morphology, water temperature, available light and nutrient inputs. Given the description of several algal categories, POTAMON allows to simulate algal "successions" at a particular site, as well as longitudinal changes of potamoplankton composition and biomass. The algal categories differ by their physiology, their loss rates, and their sensitivity to grazing by zooplankton. Two zooplankton categories were considered, Brachionus-like and Keratella-like, which differ by their clearance rate, their incipient limiting level, their selectivity towards phytoplankton, and their growth yield. The model simulates satisfactorily the onset and the magnitude of the phytoplankton spring bloom in the Belgian part of R. Meuse, the biomass decrease in early summer, and the autumn bloom. It also renders the major variations of algal assemblages along the river. The model allows to confirm that the main driving variables of potamoplankton dynamics in a eutrophic river are physical factors: discharge and related variables (e.g. retention time), light and temperature. In addition, the simulations confirm that the zooplankton-phytoplankton interaction may result in phytoplankton biomass fluctuations and compositional changes. POTAMON can be useful to explore plankton dynamics in a large river, and it may become a tool to test various management measures. [less ▲]

In Meniere's disease, the increase of extracellular potassium concentration in the perilymph is thought to play a key role in determining the progressive loss of cochlear hair cells. In this paper, we describe a serum-free culture preparation of hair cells from 5 day-old rat and report the release by the cochlea, in response to an increase of extracellular potassium concentration, of a cytotoxic activity active on hair cells and auditory neurons. The toxic activity is associated with low molecular weight (less than 10,000 Dalton) molecule(s) as revealed by ultrafiltration. Morphological studies performed on the organ of Corti incubated during 24 h in the presence of the cochlea-derived toxic activity (CTA), show that this factor is toxic for hair cells and not for supporting or surrounding cells. The release of CTA occurs both in the spiral ganglion and in the organ of Corti. We suggest that this cochlea-derived toxic activity may play an important role in the pathophysiology of the hearing loss that occurs during the progression of Meniere's disease. [less ▲]
