AbstractAbstract PDF
Androgen insensitivity syndrome (AIS) is a hereditary disorder that's characterized by the female phenotype in spite of the 46, XY karyotype, and this is caused by mutation of the androgen receptor gene. We experienced a case of the complete type of AIS. A 20-yr-old woman was evaluated for primary amenorrhea. The patient had external genitalia of the female phenotype, but she had no ovaries or uterus. The abdominal computed tomography scan revealed suspected testes in the pelvic cavity. The chromosome analysis was reported as 46, XY. We identified an androgen receptor gene novel mutation, including CAT deletion at the position 1925~1927 and AG deletion at the position 2129~2130 of exon 5, in both the proband and her sister. The patient underwent laparoscopic gonadectomy due to the possibility of malignant tumor developing in the testes. The subject is now on estrogen supplementation and she is under regular follow-up; she is in a good condition.

AbstractAbstract PDF
Patients with Down's syndrome have an increased prevalence of autoimmune disorders that affect both the endocrine and non-endocrine organs. The most common thyroid abnormality in Down's syndrome is subclinical hypothyroidism (12.5~32.5%). The occurrence of Down's syndrome in conjunction with hyperthyroidism is rare (0.6~2.5%). A 35-year old female was transferred to our hospital because of hypotension and mental change. She had suffered from a poor oral intake and general weakness for the previous 1 week. She had been admitted local hospital and was diagnosed as hyperthyroidism. On the third day after admission, she lost consciousness and was then transferred to University Hospital. Physical examination revealed hypotension (76/39 mmHg), sinus tachycardia (111/min) and tachypnea (28/min). The upward-outward slant of the palpebral fissures, epicanthal folds, low-set ears, short stature and clinodactyly were all identified. The thyroid gland was not enlarged and there was no evidence of ophthalmopathy. The serum free T4 concentration was 3.32 ng/dL, the T3 level was 212 ng/dL and the TSH level was 0.01 uIU/mL. She was positive for TBII. Abdominal computed tomography showed ascites and pneumoperitoneum. Primary closure was done on the duodenal ulcer perforation site. She was treated with transrectal propylthiouracil and intravenous esmolol. Chromosomal analysis revealed 47XX and 21 trisomy. She was finally diagnosed as Down's syndrome, Graves' disease and duodenal ulcer perforation. Her hyperthyroidism was controlled with PTU 100 mg after discharge.

AbstractAbstract PDF
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder characterized by the combined occurrence of parathyroid, pancreatic islet and pituitary gland tumors. It is caused by mutation of the MEN1, a tumor suppressor gene, with more than 400 different MEN1 mutations having been described. Herein is reported the case of a 26-year-old woman who had complained of personality and behavior changes, coupled with repetitive loss of consciousness. Her random plasma glucose and insulin were 68 mg/dL and 67.3 microIU/mL, respectively. Two pancreatic masses were noted on abdominal computed tomography, with hypercalcemia noted from a routine chemistry test. Her diagnosis was that of MEN1; therefore, her first-degree relatives were also screened. DNA analysis was also performed, from which a MEN1 gene mutation (738del4 -> new nomenclature: 628del4) was detected. Knowledge of the MEN1 mutation status could provide early recognition of a tumor.

AbstractAbstract PDF
Osteogenesis imperfecta (OI) is a congenital disorder of type I collagen, with variable phenotypes, due to increased bone fragility and low bone mass. Previous pharmacological treatments for OI have been attempted with calcitonin and growth hormone but with little beneficial effects. Recently, Glorieux reported the beneficial effects of bisphosphonates in OI. METHODS: In this study, the effects of pamidronate treatment were evaluated in 9 patients with OI. All patients received intravenous pamidronate infusions, which was dose adjusted according to the patients' age. The outcome measures included the biochemical bone markers; serum alkaline phosphatase, urine deoxy-pyridinoline, urine Ca/Cr ratio, and bone mineral density (BMD). RESULTS: Serum alkaline phosphatase, urine deoxypyridinoline, and urine Ca/Cr ratio were slightly decreased after 1 year of therapy, although these changes were not statistically significant. The BMDs of the lumbar spine and proximal femur were significantly increased after 1-year of pamidronate treatment. No fractures were reported during the 1 year treatment periods. CONCLUSION: Pamidronate treatment had an effect on the BMD in osteogenesis imperfecta, probably due to decreasing bone resorption

AbstractAbstract PDF
Osteogenesis Imperfecta (OI) is a relatively rare hereditary disease, which is characterized by multiple bone fractures and spine scoliosis, due to the fragility of bone, and is often associated with blue sclerae, deafness and dentinogenesis imperfecta. Four types of OI can be distinguished, according to the clinical findings. Although mutations affecting type I collagen are responsible for the disease in most patients, the mechanism by which the genetic defects cause abnormal bone development remains to be fully understood. Here, the clinical characteristics of 10 OI patient cases are reported, with a review of the literature. All the cases, including 4 type I, 4 type III and 2 type IV, inherited OI as an autosomal dominant trait. All the subjects had multiple old fractures and decreased bone densities. In this study, the biochemical marker of bone formation, serum alkaline phosphatase, was found to be increased only in the pediatric OI patients, while the biochemical marker of bone resorption, urinary deoxypyridinoline, was increased in all cases. The mobility score was found to correlate with the severity of the type on diagnosis.
