Multiple endocrine neoplasia (MEN) is a combination of endocrine tumor associations and consists of 3 types: 1, 2A and 2B. Herein, we report a case of insulinoma which is combined with pheochromocytoma discovered at the left adrenal gland which was treated by surgical resection. We think there is a possibility of a new type of multiple endocrine neoplasia (MEN).

The pancreas is a mixed exocrine and endocrine gland involved in the control of many homeostatic functions.During embryogenesis,the pancreas arises from dorsal and ventral evaginations of the foregut,which subse- quently fuse into a single organ.The characterization of early genes expressed in the developing pancreas is critical to understand its specification and differentiation.Pdx1 is one of the earliest markers of pancreatic development and a key molecule in its development.Sox proteins form a large class of transcriptional regulators implicated in the control of a variety of developmental processes.One member of this family,Sox9,is expressed in the developing pancreas, but little is known about the function of Sox9 in the developing pancreas.We further investigated Sox9 function during pancreatic development in Xenopus .Using a hormone-inducible inhibitory mutant of Sox9 ,we found that Pdx1 expres- sion was reduced in the ventral pancreatic buds in Sox9-depleted embryos.We suggest that Sox9 gene expression may be involved in pancreatic development in Xenopus.

Pathological proliferation of Brgnners gland is rare, and its wide range of morphologieal variations have led to confusing the terminology with considerable lack of agreement. Six cases of duodenal nodular lesions which consisted of pathological proliferation of Brunners glands were examined by light microscopy. Polypectomy was made in two cases, and the remaining 4 cases were examined with endoscopic biopsy materials. Two polypectomy specimens, 2 cm and 3 cm each in great diameters, consisted of protruded ovoid mass with broad and short stalks. Microacopically, all of 6 cases revealed thin strands of fibrous connective tissue which separated the normal-looking Brunners glands in lobules. Individual lobules were composed of groups of acini formed by cuboidal cells admixed with occasional endocrine cells. Presence of glandular and ductal configuration of the Brunners gland aside from thick, randomly arranged bundles of smooth muscle were featured without distinct relation to interlobular septa. Also, one polypectomy case disclosed the nests of fat cells interspersed with the glandular acini. One mucosal biopsy case contained not only the smooth muscle bands but also the intimate mixture of both acini and ducts. We conclude that some of heterogeneous composition of duodenal nodular proliferation of Brunners gland is indicative of a hamartomatous growth.

In Taiwan, thyroid cancer is the most common endocrine gland malignancy and the incidence of thyroid cancer has increased four-fold in the past two decades. Fine-needle aspiration is an accurate and cost-effective method of evaluating thyroid nodules and has been the gold-standard diagnostic tool for thyroid tumors in Taiwan since the 1980s. This article reviews the history, current practice, reporting systems, training, and quality assurance for thyroid fine-needle aspiration cytology in Taiwan.

This article reports the clinical features and endocrine and metabolic features of 4 children with Prader-Willi syndrome (PWS). All the patients were female and aged 6-12 years at diagnosis. All of them had clinical manifestations of obesity, unusual facies, developmental retardation, and intellectual disability. Genetic detection showed that 2 patients had paternal deletion of the 15q11.2-q13 region, one patient had maternal autodiploid in the 15q11.2-q13 region, and one patient had no abnormality in the 15q11.2-q13 region. All patients had varying degrees of endocrine and metabolic disorders: 2 patients had short stature, among whom one had delayed appearance of secondary sex characteristics and the other one had type 2 diabetes; one patient had insulin resistance and no mammary gland development; one patient had a body height of P-Pand precocious puberty. Patients with PWS have various endocrine disorders, so long-term endocrine follow-up and management is very important.

Over the last decades, the onset of puberty in girls has occurred earlier, but the tempo of pubertal progression has been relatively slower, resulting in a younger age at puberty onset without a change in age at menarche. Sufficient energy availability and adiposity contribute to early pubertal development, and environmental factors, such as endocrine-disrupting chemicals (EDCs), may affect not only the control of energy balance, but also puberty and reproduction. EDCs are hormonally active substances that can perturb puberty by acting both peripherally on target organs, such as adipose tissue or adrenal glands, and/or centrally on the hypothalamic-pituitary-gonadal (HPG) axis. Depending on whether the exposure takes place earlier during fetal and neonatal life or later during early childhood, EDCs can lead to different outcomes through different mechanisms. Evidence of associations between exposures to EDCs and altered pubertal timing makes it reasonable to support their relationship. However, human epidemiologic data are limited or inconsistent and cannot provide sufficient evidence for a causal relationship between EDC exposure and changes in pubertal timing. Further investigation is warranted to determine the overall or different effects of EDCs exposure during prenatal or childhood windows on pubertal milestones and to reveal the underlying mechanisms, including epigenetic marks, whereby early-life exposure to EDCs affect the HPG-peripheral tissue axis.

The primary hyperparathyroidism is a complex endocrine disease caused by neoplasm or diffuse hyperplasia of parathyroid gland in which excessive paratyroid hormon is secreted. This results in chemical abnormalities of serum, and exerts major influences on the bone, kidney and gastrointestinal tract. The authors report 2 cases of primary hyperparathyroidism with review of the literature.

Multiple endocrine neoplasia (MEN) is defined as a disorder with neoplasms in two or more different hormonal tissues in several members of a family. MEN1, or Wermer's syndrome, is inherited as an autosomal dominant trait. This syndrome is characterized by neoplasia of the parathyroid glands, enteropancreatic tumors, anterior pituitary adenomas, and other neuroendocrine tumors with variable penetrance. Inherited medullary thyroid carcinoma (MTC) consists of MEN2A, MEN2B, and familial medullary thyroid cancer (FMTC). The identification of hereditary MTC has been facilitated in recent years by direct analysis of germline RET proto-oncogene mutation.

Multiple endocrine neoplasis type 2a(MEN 2a) is an inherited syndrome characterized by the occurrence of medullary thyroid carcinoma, parathyroid hyperplasia and adrenal pheochromocytoma. Adrenal Medullary disease varies from hyperplasia to bilateral multiple pheochromocyomas. In anesthetic view, stabillization of severely fluctuating vital signs has become an issue. But fluctutation of vital signs is not always ween especially large pheochromocytoms, and catecholamine releasing activity is higer in right pheochromocytoma than left. It suggests catecholamine releasing activity is affected by the site of pheochromocytoma and size of pheochromocytoma. Surgically, right adrenalectomy is more difficult than left because the vein of right adrenal gland is shorter and larger in diameter than left and it drians into the inferior vena cava directly, but in lfet, it drains into the reneal vein. Pathologically, nonfunctional of hypofunctional pheochromocytomas which have high ratio of inactivating amines. Another factor is the size of pheochromocytomas. Lager sized pheochromocytomas frequently has necrotic, hemorrhagic, cystic and myxomatous areas compared to smaller ones. In conclusion, case of bilateral adrenalectomy, more careful anesthetic management is required in right adrenalectomy and in smaller pheochromocytomas.
