Medulloblastoma is the most common malignant brain tumor in childhood. Treatment of medulloblastoma includes surgery, radiation therapy and chemotherapy. Craniospinal radiation can cause adverse effects on the endocrine system, specifically on the hypothalamic-pituitary axis. Increasing survival rates of pediatric patients with brain tumors lead to increased concern regarding long-term quality of life, including the detection and correction of endocrine disorders. One of the m...

IntroductionAmiodarone is a drug commonly used for the treatment of refractory atrial or ventricular arrhythmias. In 20% of patients, amiodarone may cause subclinical or clinically overt hypothyroidism or hyperthyroidism. The high iodine exposure caused by amiodarone treatment interferes with thyroid autoregulation. Two underlying mechanisms are considered to be involved in the pathogenesis of amiodarone-induced thyrotoxicosis (AIT). AIT1 is more common ...

BackgroundIt is known that the thyroid gland is sensitive to the damaging effects of irradiation, and patients who have received radiotherapy for tumor treatment require regular thyroid screening subsequently. A few cases of thyroid cancer after receiving 131I-metaiodobenzylguanidine (MIBG) therapy in the treatment of neuroblastoma in childhood have been described (HM van Santen et al 2012; SC Clement et al, 2013). Here, we report the two cases of papill...

Introduction: Pseudohypoparathyroidism (PHP) is a group of heterogeneous disorders causing parathyroid hormone (PTH) resistance. The features could include Albright’s hereditary osteodystrophy phenotype (AHO) [brachydactyly, short stature, obesity, round face, ectopic ossifications, intellectual disability]. The condition is rare with an estimated prevalence of 0.34-1.1 in 100,000 and the clinical presentation can be variable. Herein, we present 8 patients with PHP from t...

Children and adolescents treated for solid brain tumors with chemotherapy and craniospinal irradiation are at increased risk of metabolic changes development. Current follow-up guidelines for cancer survivors recommend to monitor fasting glucose and HbA1 levels for diabetes/impaired glucose tolerance screening in these patients. The aim of our study was to evaluate metabolic changes in children treated for medulloblastoma with oral glucose tolerance test (OGTT). We examined 63...

Introduction: Hyperparathyroidism-jaw tumour syndrome (HPT-JT) is a rare disorder, which is frequently characterized by the development of parathyroid carcinomas and atypical parathyroid adenomas and, thus, severe course of primary hyperparathyroidism (PHPT).Case reports: Two patients (1 male and 1 female, 18 y.o. and 13 y.o. at the time of diagnosis of PHPT, respectively) among a cohort of young patients (<40 y.o.) with PHPT, underwent next...

Hypercortisolism due to Cushing disease is an extremely rare condition in children under one year of age. We present a case of a 10-month-old boy with lung cystic dysplasia and pituitary blastoma (ACTH-secreting). The disease manifested with symptoms of hydrothorax due to cystic dysplasia of the right lung’s upper lobe. Surgical resection of the affected area has been carried out. Symptoms of endogenous hypercortisolism appeared soon after lung surgery. Cushing disease du...
