Craniopharyngiomas (CPG) have complex treatment challenges due to their proximity vital structures, surgical and radiotherapeutic complexities, the tendency for recurrence. The aim of this study was identify prevalence endocrine metabolic comorbidities observed during initial diagnosis long-term follow-up in a nationwide cohort pediatric CPG patients. A further highlight difficulties associated with management.

Established reference values are critical for the interpretation of immunologic assessments. In particular, proportion and absolute counts T- B- cell subpopulations subject to change with age ethnicity. We aimed establish age- specific lymphocyte subsets using updated immunophenotyping panels.We studied a total 297 healthy Turkish subjects aged 0 50 years, stratified into major brackets in cluster factor 10 per age-group. The predetermined intervals contained randomly allocated participants...

Large cell calcifying Sertoli tumours (LCCSCTs) are one of the infrequent causes prepubertal gynaecomastia. Most these in content Peutz-Jeghers syndrome (PJS) or other familial syndromes (Carney complex).Here, we report a long-term follow-up an 8.5-year-old boy with diagnosis PJS, who presented bilateral gynaecomastia, advanced bone age and accelerated growth velocity, were found to have multifocal testicular microcalcifications. As findings compatible LCCSCT, anastrozole was initiated....

Osteonecrosis (ON) is bone death caused by inadequate blood supply and its optimal management remains uncertain. We describe the outcomes of BP (pamidronate) treatment in our patients. Data regarding clinical, laboratory, magnetic resonance imaging (MRI) studies, mineral density measurements (BMD) were recorded before one year after (reevaluation). The severity clinical picture was assessed using criteria common terminology for adverse events (CTCAE). There four female patients (patient 1,...

Both body weight (BW)- and surface area (BSA)-based dosing regimens have been recommended for growth hormone (rhGH) replacement. The aim was to compare the two determine if either resulted in inadequate treatment depending on anthropometric factors.The retrospective study included children diagnosed with idiopathic isolated deficiency. BW-based mcg/kg/day converted BSA mg/m2/day equivalent amounts of given rhGH. Those a BW-to-BSA ratio more than 1 were allocated “relatively over-dosed...

Primary pigmented nodular adrenocortical disease (PPNAD) is a rare genetic mainly associated with Carney complex (CNC), which caused by germline mutations of the regulatory subunit type 1A (RIα) cAMP-dependent protein kinase (PRKAR1A) gene. We report three cases suffering from CNC unique features in diagnosis and follow-up. All had obesity cushingoid appearance exhibited laboratory characteristics hypercortisolism. However biochemical radiological examinations initially suggested Cushing's...
