Polycystic ovaries were defined with ultrasound imaging in a series of 173 women who presented to a gynaecological endocrine clinic with anovulation or hirsutism. Polycystic ovaries were found in 26% of women with amenorrhoea, 87% with oligomenorrhoea, and 92% with idiopathic hirsutism--that is, hirsutism but with regular menstrual cycles. Fewer than half the anovulatory patients with polycysti...

Insulinoma is a rare pancreatic endocrine tumor, typically sporadic and solitary. Although the Whipple triad, consisting of hypoglycemia, neuroglycopenic symptoms, and symptoms relief with glucose administration, is often present, the diagnosis may be challenging when symptoms are less typical. We report a case of road accident due to an episode of loss of consciousness in a patient with pancre...

The relentless nature and increasing prevalence of human pancreatic diseases, in particular, diabetes mellitus and adenocarcinoma, has motivated further understanding of pancreas organogenesis. The pancreas is a multifunctional organ whose epithelial cells govern a diversity of physiologically vital endocrine and exocrine functions. The mechanisms governing the birth, differentiation, morphogen...

Introduction: Thyroid nodules are a common clinical entity found among the adult general population. With increasing use of imaging investigations like ultrasonography, there has been a significant rise in the detection of non-palpable thyroid nodules that require further evaluation and management. The routine use of FNAC has reduced the number of unnecessary surgical procedures for thyroid nod...

The author reports a typical but rare case of non-functioning well differentiated endocrine carcinoma of the pancreas. A 67-year-old man was admitted to our hospital because of abdominal pain. No hormone-related symptoms were recognized. He has no familiar history of pancreatic neoplasms. Various imaging modalities including US, CT and MRI revealed a tumor of the pancreatic body. Distal pancrea...

Background: MEN1 is a rare hereditary syndrome which manifests a variety of endocrine and non-endocrine neoplasms and lesions. Introduction: A 59 year-old male with good clinical status was referred to our hospital due to chronic episodes of diarrhea. Imaging studies revealed multiple polyps in various parts of the colon, a pancreatic tail tumor, 2 hepatic lesions, bilateral adrenal hyperplasia...

Primary hyperparathyroidism is a frequent and potentially debilitating endocrine disorder for which surgery is the only curative treatment. The modalities of parathyroid surgery have changed over the last 2 decades, as conventional bilateral neck exploration is no longer the only surgical approach. Parathyroid scintigraphy plays a major role in defining the surgical strategy, given its ability ...

Pancreatic neuroendocrine tumors (PNETs), a group of endocrine tumors arising in the pancreas, are among the most common neuroendocrine tumors. The genetic causes of familial and sporadic PNETs are somewhat understood, but their molecular pathogenesis remains unknown. Most PNETs are indolent but have malignant potential. The biological behavior of an individual PNET is unpredictable; higher tum...

Hormones regulate metabolic homeostasis through interlinked dynamic networks of proteins and small molecular weight metabolites, state-of-the-art chemical technologies have been developed to decipher these complex pathways. Stable-isotope tracers largely replaced radiotracers measure flux in humans, building on advances nuclear magnetic resonance spectroscopy mass spectrometry. These are now be...

BACKGROUND Fanconi anemia (FA) is an inherited disorder with chromosomal instability, bone marrow failure, developmental defects, and a predisposition to cancer. Systematic and comprehensive endocrine function data in FA are limited. OBJECTIVE We studied a cohort of FA patients enrolled in the National Cancer Institute's Inherited Bone Marrow Failure Syndrome study. STUDY DESIGN AND PATIENT...
