Background: It has been suggested that the damage observed in invasive amebiasis is related to interactions between polymorphonuclear leukocytes (PMN) and Entamoeba histolytica trophozoites. We analyzed the relation between infiltrating inflammatory cell populations and E. histolytica density in intestinal amebic lesions.

Background/aims: Significant endothelial dysfunction as determined by lower flow-mediated vasodilation of the brachial artery was recently reported by us in growth hormone-deficient (GHD) adolescents. The circulating concentrations of markers of vascular endothelial cell and platelet activation and their relationship to inflammatory markers have not been previously evaluated in this group of patients.

Objective: To assess the relationship between circulating levels of high-sensitivity C-reactive protein (CRP) and soluble markers of vascular endothelial cell activation in GHD adolescents.

Background: Patients with advanced skin cancer present a unique challenge to neurosurgeons. Treatment involves aggressive surgical intervention and lengthy reconstructive procedures with considerable morbidity to obtain adequate and safe oncological margins. We reviewed our experience with BioGlue Surgical Adhesive, a protein-based adhesive, as an adjunct in free tissue transfer procedures to prevent CSF leakage and seroma formation.

Acute synovitis, fever and rash possibly caused by metallic debris from a loosened knee prosthesis in a patient with rheumatoid arthritis.

J Clin Rheumatol

Centro Nacional de Enfermedades Reumáticas, Division of Rheumatology, Hospital Universitario de Caracas, Hospital de Clínicas Caracas, Caracas, Venezuela.

A 39-year-old woman with long-standing seropositive rheumatoid arthritis who had a total replacement of her left knee with a modular prosthesis in 1994 presented with fever, pruritic rash, and acute synovitis of that joint following local trauma. Synovial fluid showed a charcoal-like color, and contained abundant phagocytes laden with metal particles. In patients with rheumatoid arthritis who have undergone total joint replacement, metal particle reactions and possible hyper-sensitivity should be added to the list of potential causes of superimposed acute synovitis and systemic manifestations.

Objectives: To evaluate insulin sensitivity from data obtained from baseline values and from an oral glucose tolerance test (OGTT) in normal and obese children and adolescents.

Study Design: We recruited 89 children 4-10 years old and 82 adolescents 11-18 years old divided into moderately obese (Mod OB), severely obese (Severe OB), and non-obese (Non-OB) controls. We evaluated the relationship between four simple measures of insulin sensitivity: homeostatic model assessment (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), fasting glucose to insulin ratio (FGIR), and fasting insulin resistance index (FIRI), with an insulin sensitivity measure derived from the standard 2-hour OGTT, the composite whole body insulin sensitivity index (ISI Comp).

Metabolic abnormalities in growth hormone deficiency.

Pediatr Endocrinol Rev

December 2004

Pediatric Endocrine Unit, Hospital de Clinicas Caracas, Venezuela.

Growth hormone has been implicated in the regulation of cardiovascular function and growth hormone deficiency (GHD) has been postulated to be one of the main factors responsible for the increased morbidity and mortality from cardiovascular disease in both young and older patients with childhood- and adulthood-onset GHD. Growth hormone also influences bone turnover and mineral deposition. Subjects with growth hormone deficiency have been shown to have an increased cardiovascular risk as manifested by elevated fasting and postprandial lipids and by increased body fat.

A mediastinal tumor mass in a 53-year-old woman with the sole complaint of persistent cough was studied and found to be a true thymic hyperplasia associated with a unilocular thymic cyst, felt to be of the congenital type. The bilobed thymus obtained was macroscopically and microscopically normal except for the size (12 x 12 x 3.5 cm) and weight (97 g).

Background: Silastic ring vertical gastric bypass (SRVGBP) has evolved from a stapled (SSRVGBP) to a transected (TSRVGBP), and finally to a transected pouch with jejunal interposition (TSRVGBP with J-I). The creation of the gastroenterostomy evolved from a hand-sewn to a stapled and finally to a combined stapled and hand-sewn anastomosis. The circumference of the ring was increased from 5.

Long-term outcome of growth hormone therapy in children and adolescents.

Pediatric Endocrine Unit, Hospital de Clinicas Caracas, Caracas, Venezuela.

Growth hormone (GH) has been available for more than 4 decades for the treatment of GH deficiency. Initially, GH was extracted from the pituitary glands of human cadavers, but its use was discontinued following the transmission of the Creutzfeldt-Jakob virus. After the development of recombinant GH (somatropin) in 1985, an 'unlimited' commercial source of GH has been available, allowing for the treatment of a large number of short GH-deficient and -sufficient children.

Eighteen healthy, short children with normal growth during most of their childhood were evaluated after a sustained fall in weight and reduced linear growth. Growth was followed after nutritional counseling until final height. This report demonstrates the need for an appropriate-for-age weight gain in growing children as a relatively minor but prolonged caloric restriction, leading to a sustained fall in weight centiles, will affect growth velocities long term and may lead to reduced final heights.

Objectives: To distinguish which children with precocious puberty (PP) and early puberty (EP) should be treated and which followed without therapy. To determine the effect of GnRH analog treatment on the final height of treated patients and compare the effect of two different analogs on gonadotropin suppression and final height.

Study Design: Sixteen females with PP or EP with a mean chronological age (CA) of 8.

The polycystic ovary syndrome (PCOS) is associated with an increased rate of early pregnancy loss (EPL). Hyperinsulinemia is an independent risk factor for EPL and has been found to decrease levels of glycodelin and IGF binding protein-1 (IGFBP-1), two major endometrial proteins. We hypothesized that serum glycodelin IGFBP-1 concentrations would be reduced in women with PCOS during the first trimester of pregnancy.

Objective: We recently reported that children with idiopathic short stature (ISS) have decreased lumbar spine bone mineral density (BMD) that increases after 1 year of GH therapy. The aim of this study was to confirm these short-term results and to evaluate the effect of long-term GH therapy on the BMD of children with ISS.

Patients And Design: We treated a group of 16 short, slow-growing but otherwise healthy non-GH-deficient prepubertal children (8 girls and 8 boys) with a chronological age of 9.
