BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

BACKGROUND: Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. METHODS: Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. RESULTS: Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. CONCLUSIONS: Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.

5.Clinical Implications of Serum Biomarkers in Diabetic Cardiovascular Complications.
Korean Diabetes Journal 2009;33(5):363-372
Diabetes is associated with increased risk of cardiovascular disease, with atherosclerosis responsible for most associated morbidity and mortality. Atherosclerosis often causes acute thrombotic events through plaque rupture and formation of platelet-rich thrombi. The principal clinical manifestations of atherosclerosis are coronary artery disease, ischemic stroke, and peripheral arterial disease. Endothelial dysfunction, oxidative stress, and low-grade inflammation are key features in the pathophysiology of atherosclerosis.

Verrucous carcinoma of the larynx is a distinct and uncommon variant of well-differentiated squamous cell-carcinoma. The authors hybridized in situ a case of laryngeal verrucous carcinoma with DNA prebes to humman papillomavirus (HPV) 6, 11, 16, 18, 31, 33 and 35. The DNAs from the verrucous carcinoma of larynx hybridized with mixed DNA probes HPV-16/18 and 31/33/35. In addition, there was an evidence of HPV infection based on hybridization with mixed DNA probe HPV-6/11 in the adjacent papilloma tissue. By in situ DNA hybridization techniques, we clearly demonstrated human papillomavirus (HPV-16/18, and 31/33/35) related sequences in this neoplasm. These findings suggest the role of HPV-6/11 in the development of laryngeal papilloma ad HPV-16/18 and 31/33/35 probably on the progression to verrucous carcinoma.

Clostridium perfringens is an anaerobe responsible for a wide range of diseases in animals and humans. Symptoms associated with C. perfringens food poisoning are caused by enterotoxin expressed only during sporulation of C. perfringens. It has been known that only 6% of global C. perfringens isolates carry the enterotoxin gene. We found 2 strains of enterotoxigenic C. perfringens out of 33 strains isolated from various sources in Korea using PCR. It was also found that these two strains were both type A that were strongly associated with food poisoning by checking the presence of four major lethal toxins (a-, B-, e-, l-toxin) using PCR. These results suggest that foodborne illness caused by C. perfringens may be common in Korea and that public education is necessary to prevent contamination of foods by this organism.

The authors examined 9 condylomas, 26 cervical intraepithelial neoplasms(CIN) and 22 invasive squamous cell carcinomas for the presence of human papillomavirus(HPV) DNA sequences by DNA-DNA in situ hybridization. In situ hybridization revealed target HPV DNA sequences mostly in the nuclei of the superficial cells from epithelium which contained either maturation or koilocytotic atypias. With the use of biotinylated HPV DNA probes 6/11, 16/18 and 31/33/35, 42 of the 57(73.7%) were positive with HPV-6/11, 23 with HPV-16/18, 32 with HPV-31/33/35 and 18 with two or more mixed probes. HPV-31/33/35 was wht most prevalent in CIN and invasive squamous cell carcinomas, follwed by HPV-16/18. The incidence of HPV DNA increased from 66.7% to 86.4% with increasing severity of the lesions from condylomas to invasive squamous cell carcinomas. Flat condyloma was most freuently accompanied by CIN.

Journal of the Korean Neurological Association 1999;17(2):319-325
Mirror movements(MMs) are involuntary movements executed on one side of the body during voluntary movements of the contralateral homologous body parts. Motor evoked potentials(MEP) to focal transcranial magnetic stimulation(TMS) have postulated that abnormal ipsilateral corticospinal tract is active in the patient with congenital MMs. MEP and post-MEP SP following to focal TMS were investigated in a patient with the Klippel-Feil syndrome(KFS) showing MMs and in five normal volunteers. In the patient unilateral transcranial stimulation evoked bilateral motor responses of normal latencies and SP was observed bilaterally, which tended to be shortened in duration. In the condition of KFS, the mechanism of MMs has been attributed to the presence of abnormally activated ipsilateral corticospinal tract, but it does not suffice for explaining the shortened SP. We propose that concurrent activation of both motor cortices be responsible for the mechanism of MMs in this case of KFS, in addition to the abnormality of the corticospinal tracts.
