Although there has been a considerable research in psychoneuroendocrinology, particularly in relation to the biology of mood disorders, there has been a paucity of research regarding the effects of psychological factors on endocrine diseases. Of the existing literature, the most research is focused on diabetes mellitus, graves' disease. Especially diabetes appears to be the only endocrine disease that has been the focus of recent research studies. Most of the studies had retrospective designs or several methodological flaw. There has been no consistent results demonstrating that psychological factors affect the onset of diabetes mellitus. Several studies have suggested that psychological factors affect the course of diabetes. A small number of studies showed some evidence that psychological stress was associated with changes in glucose regulation in a subset of diabetic patients. There was also evidence to suggest that some temperament and coping skill influence glycemic control in child, adolescent diabetics. Studies of behavioral or psychosocial intervention on diabetic control have been small and have produced mixed results. There was a few controlled study suggested that stressful life events might be a causal role in Cushing's disease and Graves'disease, but there is no presently sufficient evidence to suggest that psychological factors affect the onset and the course of Cushing's disease and Graves' disease. In future, there is need for a well-designed biopsychosocial research with prospective designs, well defined patient population and control groups to study the relationship between psychological factors and endocrine diseases.

Inborn errors of metabolism (IEM) are very rare and genetically transmitted diseases and have man y different symptoms related with multisystemic involvement. More rarely, endocrinopathies can be an early and first symptom of IEM, but presents with signs of later complications in adolescent or adulthood. The mechanisms of endocrine dysfunction in IEM are poorly understood. Hypogonadotropic hypogonadism is common in hemochromatosis, adrenoleukodystrophy, galactosemia, and glycogen storage disease. Many girls with classic galactosemia are at high risk for premature ovarian insufficiency (POI), despite an early diagnosis and good control. Mitochondrial diseases are multisystem disorders and are characterized by hypo- and hypergonadotrophic hypogonadism, thyroid dysfunction and insulin dysregulation. Glycogen storage disorders (GSDs), especially type Ia, Ib, III, V are assocciated with frequent hypoglycemic events. IEM is a growing field and is not yet well recognized despite its consequences for growth, bone metabolism and fertility. For this reason, clinicians should be aware of these diagnoses and potential endocrine dysfunction.

Thyroid cancer is the most common endocrine neoplasia. The medullary thyroid carcinoma (MTC) is one of the most aggressive forms of thyroid malignancy,accounting for up to 10% of all types of this disease. The mode of inheritance of MTC is autosomal dominantly and gain of function mutations in the RET proto-oncogene are well known to contribute to its development. MTC occurs as hereditary (25%) and sporadic (75%) forms. Hereditary MTC has syndromic (multiple endocrine neoplasia type 2A, B; MEN2A, MEN2B) and non-syndromic (Familial MTC, FMTC) types. Over the last two decades, elucidation of the genetic basis of tumorigenesis has provided useful screening tools for affected families. Advances in genetic screening of the RET have enabled early detection of hereditary MTCs and prophylactic thyroidectomy for relatives who may not show any symptom sof the disease. In this review we emphasize the main RET mutations in syndromic and non syndromic forms of MTC, and focus on the importance of RET genetic screening for early diagnosis and management of MTC patients, based on American Thyroid Association guidelines and genotype-phenotype correlation.

Endometriosis is classically defined as the growth of endometrial glands and stroma at extra-uterine sites. Although it is a common gynecological problem accompanied by chronic pelvic pain, infertility, and adhesion formation, the etiology of this disease is unknown. Endometriosis pathogenesis may involve endocrine and immune dysregulation since uterine endometrial growth is regulated by sex hormone in concert with bioactive mediators produced by uterine immune and endocrine cells.

Endometriosis is classically defined as the growth of endometrial glands and stroma at extrauterine sites. Although it is a common gynecological problem accompanied by chronic pelvic pain, infertility, and adhesion formation, the etiology of this disease is unknown. Endometriosis pathogenesis may involve endocrine and immune dysfunction since uterine endometrial growth is regulated by sex hormones in concert with bioactive mediators produced by uterine immune and endocrine cells. Thus, exposure to environmental toxicants disrupting endocrine and immune responses potentially affect the development and progression of endometriosis.

The government neonatal screening program has a 17-years history. Therefore, it can now provide information on the prevalence of endocrine and metabolic diseases which included in neonatal screening. Knowledge of the prevalence of metabolic diseases is very important with these results, the most effective screening methods can be determined and diseases can be identified that should be added to neonatal screening. For these purposes regular follow-up of patients with metabolic diseases and quality assuarance are also needed.

Accumulated data on medical care utilization among the insured in Korea Medical Insurance Corporation can explain the health status of the population. The purpose of this study was to analyze a change of the disease-mix and utilization pattern by controlling the size of the population enrollment. Major findings of the study are as follows : 1. The changes of inpatient disease-mix a. Utilization rate was 139.2% in 1988 against 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. Meanwhile, disease groups seen less often were infections and parasistic diseases, diseases of blood and bloodforming, diseases of the digestive system etc. c. Utilization rate was up 106.3% in 1988 compared to 1985, and diseases above that average level were ill-defined intestinal infections, chronic liver disease and cirrhosis, diabetes mellitus, essential hypertension, etc. d. The disease-mix by institution in 1988 compared to 1985 shows that chronic disorders rank high in general hospitals whereas opthalmologic, obstetric, and orthopedic diseases rank high in private clinics. 2. The changes of outpatient disease-mix a. Utilization rate was up 175.2% in 1988 compared to 1980. b. Disease groups higher than the average utilization rate included neoplasms, endocrine, nutritional and metabolic diseases and immunity disorders, mental disorders etc. And disease groups seen less often were infections and parasistic diseases, diseases of the respiratory system, diseases of the genitourinary system. etc. c. Utilization rate was up 104.0% in 1988 compared to 1985, and diseases above that average level were gastric ulcer, diseases of hard tissues of teeth, etc. And diseases seen below that average level were acute nasopharyngitis(common cold). acute upper respiratory infections of multiple or unspecified sites, etc. It was concluded that medical care utilization level was increased, and that, from 1980 to 1988, disease-mix shifted to the chronic disorders. Chronic disorders accounted for more medical care utilization in general hospitals.

To find the risk of cardiovascular disease for breast cancer patients received postoperative adjuvant anticancer therapy, this study was investigated the change of serum lipid profile (total cholesterol and trigyiceride) and the 10 year risk score of ischemic heart disease. Medical data of 432 breast cancer patients diagnosed at the breast cancer center in an university hospital from January, 2003 to December, 2006 were collected and analysed. The results showed that the levels of total cholesterol and triglyceride were increased at the points of 2 and 5 years after operation. The margin of increase of total cholesterol was higher in the patients without endocrine therapy compared to them with endocrine therapy, however there were no changes in the level of triglyceride regardless of endocrine therapy. There were also no significant changes in total cholesterol and triglyceride levels between chemotherapy, radiotherapy and endocrine therapy. 10 year-risk score of ischemic heart disease was increased by 0.44%p in the final observation compared to that of a baseline.

Immoderate energy intake, a sedentary lifestyle, and aging have contributed to the increased prevalence of obesity, sarcopenia, metabolic syndrome, type 2 diabetes, and cardiovascular disease. There is an urgent need for the development of novel pharmacological interventions that can target excessive fat accumulation and decreased muscle mass and/or strength. Adipokines, bioactive molecules derived from adipose tissue, are involved in the regulation of appetite and satiety, inflammation, energy expenditure, insulin resistance and secretion, glucose and lipid metabolism, and atherosclerosis. Recently, there is emerging evidence that skeletal muscle and the liver also function as endocrine organs that secrete myokines and hepatokines, respectively. Novel discoveries and research into these organokines (adipokines, myokines, and hepatokines) may lead to the development of promising biomarkers and therapeutics for cardiometabolic disease. In this review, I summarize recent data on these organokines and focus on the role of adipokines, myokines, and hepatokines in the regulation of insulin resistance, inflammation, and atherosclerosis.

Secondary hyperparathyroidism (SHPTH) occurs commonly in patients with end-stage renal disease (ESRD). Uncontrolled SHPTH is associated with complications of calcium deposition including calciphylaxis and elevated rates of cardiovascular morbidity. Current treatment recommendations for medically refractory disease include total parathyroidectomy, often with autotransplantation (TPTH+AT) of minced parathyroid gland. Surgical intervention is associated with a reduction in cardiovascular mortality. We report a case of a 56-year-old man with ESRD who developed SHPTH and underwent TPTH+AT of parathyroid tissue into the right brachioradialis muscle. Over the course of 7 years he developed a mass at the site of the autotransplanted gland as well as recurrent refractory hyperparathyroidism with increased forearm uptake noted on sestamibi scan. After excision of this mass, pathology demonstrated hyperplasia of the minced gland fragments which were embedded within a mass of fibroadipose tissue rather than the muscle tissue it was originally transplanted in.
