Three experiments were performed to analyze the time course of demasculinization in the Japanese quail and to test the activating and organizing effects of estradiol (E2) in adult sexually active birds. In Experiment 1, males and females were castrated at the age of 1 day or 1, 2, 4, and 6 weeks and treated as adults with testosterone (T). The age of castration had no effect on behavior and morphology in males. Plasma gonadotrophins (LH and FSH) were, however, higher in males castrated at or before than in those castrated after 2 weeks of age. This suggests that postnatal testicular secretions have organizing effects on the pituitary activity. Females which were castrated before 1 week of age were less sensitive to the activating effects of T than males, but were not fully demasculinized. The demasculinization of different reproductive characteristics such as male sexual behavior, cloacal gland size, and weight of the syringeal muscles is achieved in females at different times posthatching. In Experiment 2, castration of male and female quail at the ages of 4 days or 4 weeks confirmed that postnatal ovarian secretions contribute to the full behavioral and morphological demasculinization of females. It is easier to elicit mounting in T-treated females when they are tested in their home cage instead of a test arena. This difference was not observed in males. During Experiment 3, it was impossible to demasculinize sexually active adult males or females by treatment with Silastic implants of E2. E2 did not maintain sexual behavior in ovariectomized females showing male sexual behavior when treated with T but maintained the behavior in males. [less ▲]

Neurogenesis is known to persist in the adult mammalian central nervous system (CNS). The identity of the cells that generate new neurons in the postnatal CNS has become a crucial but elusive issue. Using a transgenic mouse, we show that NG2 proteoglycan-positive progenitor cells that express the 2',3'-cyclic nucleotide 3'-phosphodiesterase gene display a multipotent phenotype in vitro and generate electrically excitable neurons, as well as astrocytes and oligodendrocytes. The fast kinetics and the high rate of multipotent fate of these NG2+ progenitors in vitro reflect an intrinsic property, rather than reprogramming. We demonstrate in the hippocampus in vivo that a sizeable fraction of postnatal NG2+ progenitor cells are proliferative precursors whose progeny appears to differentiate into GABAergic neurons capable of propagating action potentials and displaying functional synaptic inputs. These data show that at least a subpopulation of postnatal NG2-expressing cells are CNS multipotent precursors that may underlie adult hippocampal neurogenesis. [less ▲]

Introduction: Bleeding in the postoperative period of cardiac surgery is not infrequent. Mediastinal bleeding is usually collected in a chest drainage system and discarded. Nevertheless, this blood could potentially be managed with a cell salvage device during the first six postoperative hours. This practice is generally performed only in case of a surgical re-exploration for massive bleeding and may contribute to decreased allogeneic transfusion. But in case of postoperative coagulopathy requiring medical treatment, re-exploration is usually postponed and consequently, collected blood is discarded. Therefore, chest drainage systems combined with a cell salvage option could optimize the management of blood losses and transfusions in the postoperative period, regardless of any surgical re-exploration. The aim of this study is to assess the effectiveness of such a system during the postoperative period of cardiac surgery, in patient at high risk of bleeding. Method : During a 6 months period, the CardioPAT® (Haemonetics) device was used in all cardiac surgery patients at high risk of postoperative bleeding. The following data were prospectively collected: hemoglobin level, bleeding volume, volume of autologous washed red blood cell transfused by the CardioPAT® (WRBC), volume of allogeneic red blood cell (RBC), fresh frozen plasma (FFP) or platelets (PT) transfused and surgical re-exploration. Results : The CardioPAT® was used in 16 patients during the target period. Mean postoperative bleeding volume was 338±337mL after 1 hour and 820±727mL after 6 hours. The cell salvage option was used in 9 (56%) cases and mean WRBC transfused volume was 153±212mL. One patient required surgical re-exploration. All patients transfused by WRBC received previously an allogeneic transfusion (RBC, FFP and/or PT). The hemoglobin level of blood collected in the CardioPAT® device impacted on the delay and the blood volume required for WRBC availability; lower was the hemoglobin level, larger was the volume of blood required to obtain a concentrate of WRBC. Consequently, patients with a very low hemoglobin level were anyway transfused with RBC. Conclusion : The CardioPAT® device can reduce allogeneic blood transfusion after cardiac surgery in patients at high risk of bleeding. It gives time to treat coagulopathy, leading to a decrease of surgical re-exploration. However, a device with a larger reservoir and with a flexible processing speed would be more accurate in case of major haemorrhage. Systematic utilisation of this device at the time of FFP and/or PT transfusion is a safe but expensive strategy. It seems more accurate to use this device in a permissive bleeding strategy, waiting for the spontaneous coagulation recovery of the patient, in the first postoperative hours. [less ▲]

ive changes in plasma lipid profile have been studied in six patients undergoing aortobifemoral bypass. The second day after surgery, significant changes were: decreased levels of high density lipoprotein (HDL) cholesterol (by 55%), non HDL cholesterol (by 60%) phospholipid (by 50%), pre-beta-lipoprotein (by 70%), beta-lipoprotein (by 50%), apolipoprotein A1 (by 60%) and apolipoprotein B (by 55%). The magnitude of these changes correlated positively with serum levels of transferrin and negatively with serum levels of C-reactive protein. Triglyceride levels also showed a significant decrease (by 60%) while free fatty acids increased by 70%. Changes in triglyceride levels were not correlated with serum transferrin and C-reactive protein but showed a significant negative correlation with insulin levels. Our results suggest that both inflammatory and endocrine mediators are likely implicated in the postoperative changes in lipid profile. [less ▲]

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 ▲]
