Prolactin receptor expression in gynaecomastia and male breast carcinoma.

AIMS: Despite the well-established function of prolactin (PRL) in normal breast development, its role in breast cancer pathogenesis is still controversial. PRL activity is dependent on the activation of a transmembrane protein, the PRL receptor (PRLR). The aim was to evaluate and compare PRLR expression in gynaecomastia and male breast carcinoma (MBC). METHODS AND RESULTS: PRLR expression was detected immunohistochemically in 30 cases of gynaecomastia and 30 cases of MBC. The whole series was also assessed for oestrogen receptors (ER), progesterone receptors (PR) and androgen receptors (AR).

A lower dosage levonorgestrel and testosterone combination effectively suppresses spermatogenesis and circulating gonadotropin levels with fewer metabolic effects than higher dosage combinations.

Studies using exogenous high-dosage testosterone (T) or a combination regimen of physiologic T plus high-dosage levonorgestrel (LNG) administration in normal men have shown that oligoazoospermia (<3 million/mL) or azoospermia can be achieved in the majority of the men. However, these hormonal regimens have been associated with significant weight gain and suppression of serum high-density lipoprotein (HDL) cholesterol levels. We hypothesized that a combination of physiologic exogenous testosterone and lower dosage LNG would result in uniform severe oligoazoospermia or azoospermia in normal men

The assessment of results following endocrine therapy for prostatic cancer.

Generally, recent reports on the side effects of estrogen therapy for prostatic cancer have concerned mortality statistics, relatively little attention having been paid to the quality of life of individual patients. We herein propose an assessment of treatment regimens based on the concept of the time during which a patient remains free of tumor progression or serious side effects. A particular regimen has been examined in relation to the hormonal effects of endocrine ablation, and to the dosage and type of estrogen therapy used in 59 men with prostatic cancer. Although no significant differen

Sertoli cell proliferations of the infantile testis: an intratubular form of Sertoli cell tumor?

We report on six boys with intratubular Sertoli cell proliferations (ISCPs), studied by routine histologic methods, electron microscopy, and immunohistochemistry of anti-müllerian hormone (AMH), inhibin alpha-subunit, 3beta-hydroxysteroid dehydrogenase (3beta-HSD), proliferative cellular nuclear antigen, and p53, and carefully followed for extended periods with periodic clinical examinations, testicular ultrasonographies, and determinations of serum levels of AMH and inhibin B. Peutz-Jeghers syndrome was found in four of six patients, and gynecomastia occurred in five of six patients. One boy …

Core needle biopsy for the assessment of unilateral male breast lesions.

The importance of preoperative histological diagnosis in the assessment of breast lesions in women is widely established, but in men with breast lesions histological diagnosis is obtained in a limited number of cases. The aim of this study was to report our single-center experience in a large series of 131 CNB performed for suspicious male breast lesions. Our data confirmed that CNB is an effective method in distinguishing between benign and neoplastic lesions in the male breast, thus validating the few published data. CNB should be a routine part of the unilateral male breast swelling diagnos

Drug-specific and developmental heterogeneity in adverse event profiles of atypical antipsychotics in the pediatric population: A FAERS pharmacovigilance study.

OBJECTIVE: To characterize the safety profile of atypical antipsychotics (AAPs) in the pediatric population using the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS), focusing on signal distribution, drug-specific patterns, developmental heterogeneity, and time-to-onset (TTO). METHODS: Adverse event (AE) reports involving AAPs were extracted from FAERS, and pediatric cases aged 0-17 years were identified. Descriptive analyses summarized reporting characteristics and system organ class (SOC) distributions. Signal detection was performed using the reporting odds ratio (

BACKGROUND: Various types of lesion from inflammation to carcinoma can affect breast. Some lesions are common in young females while others in elderly age group. Early presentation and prompt diagnosis is essential to relieve anxiety of non-neoplastic conditions, and in case of carcinoma, it can save the patient from metastases. Many cases related to breast lesions from the region are reported in the surgery clinics of this institute and various breast diseases are being managed in the clinical departments. Analysis of pattern and prevalence will be a valuable guideline for clinicians of this

Phase I-II trial of weekly bicalutamide in men with elevated prostate-specific antigen and negative prostate biopsies.

BACKGROUND: Men with elevated prostate-specific antigen (PSA) and negative prostate biopsies are at risk for prostate cancer. The antiandrogen bicalutamide has a prolonged half-life, thus potentially allowing an intermittent administration to retain activity while reducing toxicity. We conducted a phase I-II trial of weekly bicalutamide in men with PSA >4 ng/mL and negative biopsies. METHODS: Eighty subjects were nonrandomly assigned to a three-arm trial to either bicalutamide 50 mg/wk (n = 26) or 100 mg/wk (n = 28) or no treatment (n = 26) for 6 months. Blood samples were obtained at 0, 3, a

Glial fibrillary acidic protein immunoreactivity in normal and diseased human breast.

Immunostaining for glial fibrillary acidic protein (GFAP) identifies a minor subpopulation of immunoreactive myoepithelial cells in the normal resting human breast. The GFAP-immunoreactive cells also express a panel of myoepithelial cell markers, including cytokeratin 14 (CK 14), vimentin, smooth-muscle-specific actin isoforms, nerve growth factor receptor (NGFR) and common acute lymphoblastic leukaemia antigen (CALLA). The percentage of GFAP-immunoreactive myoepithelial cells is greatly increased in various neoplastic and non-neoplastic diseases of the breast, being highest in adenomyoepithel
