Oxytocin (OT) is implicated in stress reduction as well as in social behavior. It inhibits the stress-induced activity of the hypothalamic-pituitary adrenal axis responsiveness. OT is involved in social affiliation, sexual and maternal-infant binding, anxiety, mood, feeding control and memory. Several lines of evidence suggest a role of OT in psychiatric disorders. Various psychiatric disorders are strongly influenced by social variables, such as panic attacks, depression and early childhood autism, and seem to exhibit a particularly close connection with the brain dynamics that underlie social emotions. This paper proposes an overview of OT in psychiatric disorders through the links with the stress response and prosocial behavior. [less ▲]

Knowledge about vitamin D has greatly improved during the last few years. Vitamin D cannot any more be considered as exclusively necessary to prevent ricket/osteomalacia. Its role in the prevention of some osteoporotic fractures in the elderly (in association with calcium nutrition) is now well demonstrated and many epidemiologic and laboratory data argue for a role in the prevention of several diseases or anomalies (cancer, auto-immune diseases, cardiovascular events, sarcopenia...). A few intervention studies confirming some of these effects also exist. Vitamin D status can easily be assessed by measuring serum 25 hydroxy vitamin D (25OHD) level. However, many experts have claimed that the population-based reference values for 25OHD are too low and that the cut-off value below which vitamin D insufficiency can be present is somewhere between 20 and 40ng/mL with a clear tendency to target values above 30ng/mL (75nmol/L). The main consequences are that vitamin D insufficiency is highly frequent whereas the currently recommended supplementation doses are not sufficient. [less ▲]

Placental tissue exhibits a typical glycosylation pattern, which differs from that observed in the pituitary gland. Depending to the species and pregnancy period, the placenta synthesizes diverse glycoproteins, some of which have significant hormonal activity, others being detected in maternal circulation. Thus, these molecules are of interest both from a fundamental and clinical point of view. Among the mammalian placental glycoproteins currently recognized, chorionic gonadotrophins from primates and Equidae, placental lactogen from bovines and the pregnancy-associated glycoproteins from ruminant species are particularly noteworthy. The diversity of saccharidic structures leads to multiple forms of placental glycoproteins exhibiting distinct structural and biological properties. For instance, concerning the chorionic gonadotrophins, the association of both alpha and beta subunits is essential for the binding of the hormone to specific receptors. Moreover, the N-linked oligossacharides are required for the activation of effectors systems. Bovine placental lactogen is a glycosylated hormone, exhibiting somatotropin- and prolactin-like activities. Several N-glycosylation sites confer to pregnancy-associated glycoproteins a long half-life (8-10 days) in maternal circulation. Assay of these molecules can be used for routine early pregnancy diagnosis and the follow-up of embryonic and fetal mortalities. [less ▲]

Background Impotence and decreased libido are the cardinal features of prolactinomas in males. We describe the unusual clinical, pathological and biochemical features in a male patient with a giant prolactinoma and normal gonadal function. Case Report A 57 year-old man presented with visual symptoms related to a 30 × 25 × 60 mm tumor of the sella and skull base. Biopsy revealed a pituitary adenoma and subsequent hormone profiles demonstrated grossly elevated serum prolactin (131,412 ng/ml), LH at the upper limit of normal and normal testosterone. The patient had no symptoms of decreased libido or impotence related to this giant prolactinoma. Immunohistochemistry revealed a tumor that was positive for prolactin, alpha-subunit and LH. Cabergoline greatly reduced prolactin levels but these remained above normal. LH, testosterone and alpha-subunit levels were decreased in parallel. Loss of libido and impotence became apparent when testosterone fell below normal, a situation that resolved with further cabergoline treatment and prolactin inhibition and testosterone therapy. Conclusions Sexual dysfunction is a hallmark of prolactinomas in males. Tumors that co-secrete prolactin and LH are extremely rare and this is the first such case reported in an adult male. In this case, normal testosterone was maintained by intact LH levels even in the face of the highest prolactin level reported to date. [less ▲]

Many causes of thyroxine malabsorption are described in the literature, but the most common cause of failure of thyroxine therapy is poor patient compliance, or pseudomalabsorption. We describe the case of a female patient who underwent total thyroidectomy for Basedow-Graves disease. Post-operatively, several treatment regimens were employed to achieve euthyroidism, but only injectable thyroxine was found to be effective. To exclude levothyroxine malabsorption, the patient was hospitalized in a hypothyroid state while a single oral test dose of levothyroxine (1000 microg) was administered. Within 4 hours a decrease of TSH level (from 59.7 to 55.6 microUI/ml) and a significant increase in free T4 levels (from 0.8 to 15.5 pg/ml) was observed, eliminating a malabsorption problem. The cause of resistance to thyroid hormone therapy was poor patient compliance, leading to the designation of this as a case of pseudomalabsorption. [less ▲]

We observed oat-cell lung carcinoma in a man who presented with diabetes insipidus. The chest radiograph showed a suspect nodule within a context of major nicotine addiction. Histopathological examination of the transbronchial biopsy confirmed the diagnosis of oat-cell carcinoma. Brain CT revealed metastasis to the pituitary gland and the pituitary stalk. Vasopressin was undetectable. This case illustrates an uncommon clinical presentation of small-cell lung carcinoma. Oat-cell carcinoma can modify osmoregulation in two different ways. Only sporadic cases of neurogenic diabetes insipidus due to the primary involvement of small-cell lung carcinoma have been reported. More often, this type of lung tumor is associated with inappropriate antidiuretic hormone secretion. [less ▲]

Defects in pancreatic islet beta-cell function play a major role in the development of diabetes mellitus. Type 1 diabetes is caused by a more or less rapid destruction of pancreatic beta cells, and the autoimmune process begins years before the beta-cell destruction becomes complete, thereby providing a window of opportunity for intervention. During the preclinical period and early after diagnosis, much of the insulin deficiency may be the result of functional inhibition of insulin secretion that may be at least partially and transiently reversible. Type 2 diabetes is characterized by a progressive loss of beta-cell function throughout the course of the disease. The pattern of loss is an initial (probably of genetic origin) defect in acute or first-phase insulin secretion, followed by a decreasing maximal capacity of insulin secretion. Last, a defective steady-state and basal insulin secretion develops, leading to almost complete beta-cell failure requiring insulin treatment. Because of the reciprocal relation between insulin secretion and insulin sensitivity, valid representation of beta-cell function requires interpretation of insulin responses in the context of the prevailing degree of insulin sensitivity. This appropriate approach highlights defects in insulin secretion at the various stages of the natural history of type 2 diabetes and already present in individuals at risk to develop the disease. To date none of the available therapies can stop the progressive beta-cell defect and the progression of the metabolic disorder. The better understanding of the pathophysiology of the disease should lead to the development of new strategies to preserve beta-cell function in both type 1 and type 2 diabetes mellitus. [less ▲]
