We present a case of severe malignant pheochromocytoma complicated with intestinal pseudo-obstruction, which was refractory to conventional therapies but reacted to intravenous administration of an α-blocker, phentolamine.Malignant pheochromocytoma typically metastasizes to bones, liver, lungs, and lymph nodes, and average 5-year survival rate in the patient with metastases is approximately 50%. Treatment options for malignant pheochromocytoma inclu...

Introduction: Pheochromocytoma (PHEO) is a rare tumor of chromaffin cells with variable clinical presentation. Adrenal PHEOs secrete excessive amounts of noradrenaline or of noradrenaline plus adrenaline, whereas extra-adrenal PHEOs (paragangliomas) mostly secrete noradrenaline alone due to lack of expression of phenylethanolamine-N-methyltransferase (PNMT), the key enzyme converting noradrenaline into adrenaline. We report two exceptional cases of paragangliomas responsible f...

Background and aims: Type 2 Diabetes Mellitus affects a growing number of people allover the world. It is associated with serious complications. Several studies have shown that it is possible to prevent and minimize type 2 diabetes complications if it is treated appropriately over time. In our Hospital there is, since 1998, an outpatient clinics of diabetes. This study aimed to determine the quality of care provided to diabetic patients in our institution.<p class="abstext...

Craniofacial proportions of girls with TS, compared to normal children, show reduced size of the craniofacial complex, retrognathic profile and tendency towards advanced dental age. Growth hormone (GH) treatment in TS positively affects stature, but its effects on craniofacial growth and dental development are largely unknown. The aim of this study was to analyze and to correlate the craniofacial morphology, chronological, dental and bone ages of TS patients receiving GH or no...

Growth is a complex process, influenced to a large extent by GH. Children with GH deficiency (GHD) have typical somatic features, including short stature and a reduction of the craniofacial structures. Dental age (DA) is normally delayed in relation to chronological age (CA). The effect of GH replacement on craniofacial growth is still poorly understood. We studied the craniofacial development and dental maturation in 17 patients (4F, 13M) with GHD of different etiologies. The...

Background and aims: Thyroid nodular disease (TND) is a common condition in the general population. Malignant nodules occur in 5% of patients with thyroid nodules. Fine-needle aspiration biopsy (FNAB) is considered to be the most reliable method of differentiating benign and malignant thyroid nodules. The purpose of this study was to assess the accuracy of FNABs performed in our Hospital.Methods: We retrospectively reviewed the medical records of patient...

Background: BoneXpert software calculates bone health index (BHI) from 100 measurements of cortical thickness and mineralisation of three metacarpals. BHI-SDS is derived from 3,121 X-rays from 231 healthy Caucasian children, corrected for bone age (BA), estimated from the same x-ray.BHI-SDS is new with relatively unknown clinical utility. Strong correlations between BHI and dual-energy x-ray (DXA) absorptiometry and peripheral quantitative computed CT me...

Context11-oxygenated C19 steroids have recently gained attention as markers of androgen control in congenital adrenal hyperplasia (CAH) due to 21hydroxylase deficiency (21OHD). However, they have not yet been systematically investigated in the context of different glucocorticoid (GC) replacement regimens and in particular not in patients receiving new modified-release formulations.MethodsCross-sectional singl...

BackgroundRoutine biochemical assessment in patients with congenital adrenal hyperplasia (CAH) includes measurement of serum 17–hydroxyprogesterone (17OHP), androstenedione (A4) and testosterone (T) and their metabolites in urine. Several studies have also described 11–oxygenated 19–carbon (110 × C19) steroids as a clinically relevant androgenetic source and highlighted their potential as markers for evaluation of adrenal androgen exc...

IntroductionParagangliomas (PGL) of the urinary bladder are an extremely rare entity. During pregnancy, PGL can carry higher risk of foetal and maternal mortality, which can be significantly reduced when the diagnosis is made antepartum and adequate multidisciplinary management and surveillance is started. However, despite clinical stability, delivery complications rates are still higher than in the general obstetric population.Cas...
