BACKGROUND Antibiotic use in infancy disrupts gut microflora during a critical period for immune system development. It is hypothesized that this could predispose to the development of allergic diseases. We investigated the associations of antibiotic use in the first 2 yr of life with the development of asthma, eczema or hay fever by age 7.5 yr in a longitudinal birth cohort. METHODS Subjects...

Serum FSH and LH levels in 104 patients with disorders of sexual development were determined by radioimmunoassay and compared with serum FSH and LH levels in 164 normal individuals.32 of 35 gonadal dysgenesis patients (ages 4.8-18.9 yr) had serum FSH levels which were elevated above the range of normal for chronological age, and 19 had serum LH levels similarly elevated. All patients with eleva...

BACKGROUND & OBJECTIVE Rubella, normally a mild, self-limiting disease characterized by rash, fever and lymphadenopathy, is a vaccine preventable disease. It carries little morbidity and apparently only minor complications in children. Infection during early pregnancy may lead to congenital rubella infection. Presence of rubella specific IgG in an unvaccinated population is a long term marker o...

This paper presents unexpectedly early dates for a Tupiguarani settlement in Southeastern Brazil. One radiocarbon dating of 1740 +/- 90 yr BP (1820-1390 cal yr BP) was already available for the Morro Grande site (Araruama, southeastern coast of Rio de Janeiro State). Two new dates, obtained from charcoal samples, are reported here. An age of 2920 +/- 70 yr BP (3220-2790 cal yr BP) was obtained ...

It has been suggested that the programming of the endocrine axes occurs during critical phases of fetal development and will be affected by intrauterine growth retardation. As a result, children born small for gestational age (SGA) might have several hormonal disturbances. In later life, one of the questions that might arise is: Do short children born SGA have higher serum dehydroepiandrosteron...

Thirty five patients of either sex suffering from tuberculosis were administered streptomycin 0.75 g (im daily, upto 14 yr and above 45 yr of age) and 1 g (im daily for age 15-45 yr) with other antitubercular drugs and followed for audiological status. Five patients were dropped as they developed vestibular dysfunction. Varying degree of hearing loss was detected in 4 of 10 patients in group I ...

Background and Objectives: Gastrointestinal polyps are proliferative or neoplastic mucosal lesions. The most important point about these polyps is risk of malignancy of them. This study was performed to determine type and frequency of polyps of gastrointestinal tract in Iranian population according to their locations. Materials and Methods: Totally, 210 patients referred to Rasul-e-Akram Hospi...

Angiotensin II type 1 receptor antibodies (AT1 RAb) have emerged as non-HLA Ab present in patients with acute AMR and risk of graft loss. Furthermore, AT1 RAb have been shown to increase angiotensin II sensitivity which may play a role in the development of CVD and hypertension. Data on AT1 RAb in stable transplant recipients are lacking. The aim of this study was to analyze the levels of AT1 R...

A retrospective analysis of the poisoning calls received by the National Poisons Information Centre (NPIC) showed a total of 2,720 calls during a period of three years (April 1999-March 2002). Poisoning in children was reported in 995 calls (36.6%). The age ranged from less than 1 yr to 18 yr and the age groups involved were divided into four categories (0-6 yr, >6-12 yr, >12-16 yr, >16-18 yr)....

We used longitudinal data from the Massachusetts Male Aging Study, a large population-based random-sample cohort of men aged 40-70 yr at baseline, to establish normative age trends for serum level of T and related hormones in middle-aged men and to test whether general health status affected the age trends. Of 1,709 men enrolled in 1987-1989, 1,156 were followed up 7-10 yr afterward. By repeate...
