OBJECTIVES Metformin has shown its effectiveness in treating obesity in adults. However, little research has been conducted in children, with a lack of attention on pubertal status. The objectives were to determine whether oral metformin treatment reduces BMI z score, cardiovascular risk, and inflammation biomarkers in children who are obese depending on pubertal stage and sex. METHODS This w...

Graves' disease is less common in prepubertal than pubertal children, and initial presentation with thyroid storm is rare. We report an 11-year-old prepubertal Hispanic girl who presented with a one-day history of respiratory distress, fever, and dysphagia. She had exophthalmos, a diffuse bilateral goiter and was agitated, tachycardic, and hypertensive. Nasal swab was positive for respiratory s...

D estructive forms of periodontal diseases may have an early onset in the primary dentition. 1-~ Two types of prepubertal periodontitis (PP) have been described:1 a) generalized prepubertal periodontitis (GPP), which is characterized by severe gingival inflammation, gingival tissue proliferation, gingival recession, and a widespread and rapid destruction of the alveolar bone and b) localized pr...

The mammary glands of prepubertal estrogen receptor (ER)beta-- mice are morphologically indistinguishable from those of WT littermates. It appears that, although ERbeta is expressed in the mouse mammary gland, it is not involved in ductal growth of the gland. In this study, we examined the possibility that ERbeta has a role in the differentiated function of the mammary gland. Pregnancy is rare ...

In the present research we have investigated the distribution of the sugar residues of the glycoconjugates in the prepubertal and postpubertal testes of a subject with Morris's syndrome (CAIS, Complete Androgen Insensitivity Syndrome). For this purpose a battery of six horseradish peroxidase-conjugated lectins was used (SBA, PNA, WGA, ConA, LTA and UEAI). We have obtained a complete distributio...

Prepubertal testicular dysfunction and the subsequent development of hypogonadism affects an estimated one in 200 children worldwide. As the testosterone levels are dynamic during development and puberty, traditional hormone treatment regimens are often inadequate, thereby leaving associated physiological conditions unresolved. Therefore, we have investigated the potential therapeutic effect of...

Our objective was to determine if prepubertal rate of body weight (BW) gain, independent of diet, was related to mammary development of dairy heifers. Data from two studies recently conducted at Michigan State University were used to identify factors, within a dietary treatment group, that would account for variation in first lactation milk production or amount of mammary parenchymal DNA at the...

The oocyte-to-embryo transition in mammals depends on maternal proteins and transcripts, which accumulate during oocyte differentiation. The aim of the present study was to examine the role of the junctional proteins beta-catenin and E-cadherin during preimplantation in vitro embryo development in sheep, comparing the competence of adult and prepubertal oocytes. We analysed the concentration of...

Labial adhesions are a common finding estimated to occur in 22% of prepubertal girls. Symptoms are related to the accumulation of urine behind partially fused labia and include urinary tract infections, vulvovaginitis, pain with activity, post-void dripping of urine, and, in cases of complete labial fusion, urinary retention. Although topical estrogen had traditionally been considered first-lin...
