Russell's diencephalic syndrome of early childhood.

A case of Russell's diencephalic syndrome of early childhood is presented and the world literature reviewed. Assays of serum growth hormone (HGH) and fat mobilizing substance (FMS) were performed and gave very abnormal results. The role of these two substances is discussed and their value in the diagnosis of this syndrome is emphasized.

Plant, synthetic, and endogenous cannabinoids in medicine.

Although used for more than 4000 years for recreational and medicinal purposes, Cannabis and its best-known pharmacologically active constituents, the cannabinoids, became a protagonist in medical research only recently. This revival of interest is explained by the finding in the 1990s of the mechanism of action of the main psychotropic cannabinoid, Delta9-tetrahydrocannabinol (THC), which acts through specific membrane receptors, the cannabinoid receptors. The molecular characterization of these receptors allowed the development of synthetic molecules with cannabinoid and noncannabinoid structure and with higher selectivity, metabolic stability, and efficacy than THC, as well as the development of antagonists that have already found pharmaceutical application. The finding of endogenous agonists at these receptors, the endocannabinoids, opened new therapeutic possibilities through the modulation of the activity of cannabinoid receptors by targeting the biochemical mechanisms controlling endocannabinoid tissue levels.

Triamcinolone-induced wasting disease in young mice.

Young mice were treated for up to 8 weeks with daily graded doses of triamcinolone diacetate. The body weights of treated, placebo and nontreated animals were measured daily throughout the experimental period, calculated and analysed. By the first injections, significant decrease was noted in the body weight of all experimental mice regardless of their sex or initial bodyweight. The latter was followed by a so-called 'steady state' which longed for approximately 4 weeks. Marked deterioration and mortality also occurred but became severe from the fifth week of triamcinolone administration. Possible explanations for the above findings are discussed.

Anabolic effects of recombinant human growth hormone in patients with wasting associated with human immunodeficiency virus infection.

Body wasting, characterized by disproportionate loss of body cell mass, is a feature of many chronic diseases, including infection with the human immunodeficiency virus (HIV). Therapies that merely increase energy intake do not consistently restore body cell mass in patients with the wasting syndrome. Because treatment with GH has induced nitrogen (N) retention in catabolic patients after surgery, burns, cancer, and hypocaloric feeding, we designed this study to determine whether GH could also produce an anabolic response in persons with HIV-associated weight loss. Six HIV-positive (HIV+) men with an average weight loss of 19% and six healthy weight-stable controls (HIV-) were hospitalized on a metabolic ward, where they consumed a constant metabolic diet during successive 5-day precontrol, 7-day baseline, and 7-day treatment [recombinant human GH (rhGH), 0.1 mg/kg.day] periods. The effects of rhGH on body weight, N and electrolyte excretion, energy expenditure, substrate oxidation, and integrated lipid and carbohydrate metabolism were assessed. Body weight increased promptly and progressively during treatment (2.0 +/- 0.3 and 1.6 +/- 0.2 kg in HIV+ and HIV-, respectively). Urinary N excretion decreased by 288 +/- 17 and 287 +/- 42 mmol/day in HIV+ and HIV-, respectively. Resting energy expenditure increased by 7.5% in both groups. Protein oxidation decreased, whereas lipid oxidation increased significantly. Glucose flux increased, and modest increases in fasting plasma triglyceride, glucose, and insulin levels were observed. Thus, short term rhGH treatment increased both protein anabolism and protein-sparing lipid oxidation, effects that should increase body cell mass if sustained during chronic therapy.

Pathology of domoic acid toxicity in California sea lions (Zalophus californianus).

Over 100 free-ranging adult California sea lions (Zalophus californianus) and one Northern fur seal (Callorhinus ursinus), predominantly adult females, were intoxicated by domoic acid (DA) during three harmful algal blooms between 1998 and 2000 in central and northern California coastal waters. The vector prey item was Northern anchovy (Engraulis mordax) and the primary DA-producing algal diatom was Psuedonitzschia australis. Postmortem examination revealed gross and histologic findings that were distinctive and aided in diagnosis. A total of 109 sea lions were examined, dying between 1 day and 10 months after admission to a marine mammal rehabilitation center. Persistent seizures with obtundation were the main clinical findings. Frequent gross findings in animals dying acutely consisted of piriform lobe malacia, myocardial pallor, bronchopneumonia, and complications related to pregnancy. Gross findings in animals dying months after intoxication included bilateral hippocampal atrophy. Histologic observations implicated limbic system seizure injury consistent with excitotoxin exposure. Peracutely, there was microvesicular hydropic degeneration within the neuropil of the hippocampus, amygdala, pyriform lobe, and other limbic structures. Acutely, there was ischemic neuronal necrosis, particularly apparent in the granular cells of the dentate gyrus and the pyramidal cells within the hippocampus cornu ammonis (CA) sectors CA4, CA3, and CA1. Dentate granular cell necrosis has not been reported in human or experimental animal DA toxicity and may be unique to sea lions. Chronically, there was gliosis, mild nonsuppurative inflammation, and loss of laminar organization in affected areas.
