BACKGROUND : DHEAS, the major circulating adrenal hormone, has been suggested to have a role in many aging related diseases and perhaps in aging itself. But, there is no epidemiologic data of DHEAS in normal adults in Korea. We studied age changes and sex differences in serum DHEAS & its related factors throughout adulthood. METHODS : We administ structured questionnaires to the study subjects. We measured serum DHEAS levels and several biochemical markers (total cholesterol, triglyceride, HDL-cholesterol, glucose etc) in 1.710 healthy men(857) and women (853), aged 17-76 years. We also measured their height, weight, waist & hip circumference and body fat contents with bioimpedance method. We analyzed various variables relating to serum DHEAS levels by using SPSS. Reference data of serum DHEAS level in normal adults were also suggested. RESULTS : The DHEAS concentration peaked at age group blow age of 30 years in man(260.9 microgram/dL). Then mean values declined steadily in both sexes (r=-0.38, p<0.001 in men and r=-0.46, p<0.001 in women). At age group above 70 years, only 30.9% in men & 30.4% in women, when compared with age group below 30 years, was remained. DHEAS concentration were significantly higher in men than women at all age group except age group above 70 years. Average 1.5 times higher concentration in men than in women (at least 1.28 times at age<30 and max 2.00 times at age 60-64). In men, DHEAS had higher mean value in smokers (218.1 vs 199.1 microgram/dL, p<0.05), drinkers (>or=2 times/week, 219.1 vs 185.3 microgram/dL, p<0.01), android type fat distribution group (waist/hip>0.85, 227.1 vs 197.4 microgram/dL) after adjusting age. DHEAS was positively correlated with body mass index (r=0.12, p<0.01). But in women, drinkers (154.3 vs 131.7 microgram/dL, p<0.05) and regular exercise group (146.1 vs 131.6 microgram/dL, p=0.05) had higher mean DHEAS value. There were no significant association between DHEAS and lipid profile (total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol) & fasting glucose level in both sex. CONCLUSION : Our data suggest that DHEAS levels may influenced by several sociodemographic factors (e.g. smoking, alcohol, exercise etc) and body mass index. DHEAS level was inversely correlated by age in both sex and men had 1.5 times higher DHEAS values than women. We could not find any association between DHEAS level and lipid profile & fasting blood sugar.

Massive ovarian deema is a tate conditian. It is a benign enlargement of the ovary caused by accumulation of fluid, which is thought to result from intermittent partial toraion of the ovarian pedicle. Histologically, the ovaries were characterized by diffuse edema of medulla and inner cortex. Two cases of massive ovanan edema are reported with brief review of the literatures.

Hamartoma of the bladder is quite a rare entity which is composed of a disorderly admixture of mature cellular elements normally present in the urinary bladder. There is a great controversy regarding the pathogenesis of this lesion. Whether it is a true hamartomatous lesion or metaplastic lesion developed secondary to the inflammatory process. Similar or identical lesions has often been given by other names such as florid examples of cystitis glandularis. We prefer to cell florid examples of cystitis glandularis rather than hamartoma when it was occurred in an old age higher then 50th decade. Here we report a case of hamartoma of the urinary bladder in 44 years old man. Cystoscopic examination revealed a papillary polypoid mass which was attached to the fundus of bladder by long stalk. The mass measured 1.5 cm in greatest diameter. It was composed of epithelial nests resembling von Brunn's nest, cystitis glandularis or cystitis cystica dispersed in a stroma rich in smooth muscle and fibrous tissue.

The purpose of this study was to compare the microleakage of low and high viscosity flowable resins in class V cavities applied with 1-step adhesives. Forty class V cavities were prepared on the cervices of buccal and lingual surfaces of extracted molar teeth and divided into four groups (n=8). Cavities were restored with AQ Bond Plus/Metafil Flo alpha, G-Bond/UniFil LoFlo Plus (Low flow groups), AQ Bond Plus/Metafil Flo and G-Bond/UniFil Flow (High flow group), respectively. Specimens were immersed in a 2% methylene blue solution for 24 hours, and bisected longitudinally. They were observed microleakages at the enamel and dentinal margins. In conclusion, the low viscosity flowable resins showed lower marginal microleakage than do the high viscosity flowable resins in class V cavities.

PURPOSE: The prognosis forearly gastric cancer (EGC) is generally excellent after curative gastrectomy alone. However, the EGC of young patients was generally more invasive and metastasizing, and the prognosis of them was poorer than those of the elderly. We performed a retrospective study to evaluate clinica1 and pathological factors influencing the prognosis of EGC. MATERIALS AND METHODS: The authors investigated 66 cases of EGC resected at Inha Hospital in Song-Nam, from January 1987 to December 1996. We analyzed 9 clinicopathologic factors: age, sex, macroscopic type, tumor size, depth of invasion, location, lymph node metastasis, Williss classification and Laurens classification. RESULTS: Out of 66 cases (42 males, 24 females) of EGC, the sex ratio (M: F) was 1.75: 1, and the mean age was 55.5 years in male and 54.3 in female. The age incidence revealed a greater prevalence on 6th decade (33.3%). The most common macroscopic type of EGC was IIb and its combined type (43 cases, 65.2%). In tumor size, 16 cases (24.2%) were between 2.0 and 2.9 cm, and 13 cases (19.6%) between 1.0 and 1.9 cm, 10 cases (15%) between 3.0 and 3.9 cm. The tumors smaller than 2.0 cm were 33.2% but greater than 5.0 cm were 18.8%. In male, mucosal lesions were more common (66.6%) than submucosal lesions (33.4%); but in female, the incidence of both types of lesions were the same. The submucosal lesion in female was the most frequent at 4th decade. The major location of EGC was antrum (51.5%). Lymph node metastases were found in 3 females and 1 male. By Williss classification, poorly differentiated adenocarcinoma and signet ring cell carcinoma were more common in female (29.2%, 25%) than in male (11.9%, 14.3%). By Laurens classification, the diffuse type was more common in female (50%) than in male (33.3%). This type was the most frequent in 4th decade female patients. However, none of the above data reached statistical significance. CONCLUSION: We found the generalized tendency, though not statistically confinned, that the young female patients of EGC frequently had larger and poorly differentiated, diffuse adenocarcinomas with more frequent lymph node metastasis than male. The authors emphasizes that a further study would be needed in young female patients of EGC on hormonal factors influencing its clinicopathologic findings.

Mosaic trisomy 14 syndrome is a well-known but unusual chromosomal abnormality with a distinct and recognizable phenotype. Array comparative genomic hybridization (CGH) analysis has recently become a widely used method for detecting DNA copy number changes, in place of traditional karyotype analysis. However, the array CGH shows a limitation for detecting the low-level mosaicism. Here, we report the detailed clinical and cytogenetic findings of patient with low-frequency mosaic trisomy 14, initially considered normal based on usual cut-off levels of array CGH, but confirmed by G-banding karyotyping. Our patient had global developmental delay, short stature, congenital heart disease, craniofacial dysmorphic features, and dark skin patches over her whole body. Estimated mosaicism proportion was 23.3% by G-banding karyotyping and 18.0% by array CGH.

BACKGROUND: This study was done to investigate the clinical risk factors of delirium in general hospital's elderly inpatients. METHODS: A case-control study design was used. Forty cases and age -sex matched 120 contols were identified using hospital discharge data from June 1995 to May 2001. The controls were selected during the same period. The clinical records of each subject were reviewed using discharged disease code to select cases. Subsequent7, the data were recorded from clinical records. RESULTS: The subjects admitted with delirium tended to have increased age (P=0.007), hypoxia(P=0.018), low hemoglobin(P =0.011),sleep disturbance (P=0.001), more ADL total dependence ( P=0.018), diagnoses with infections (P=0.006), diabetes (P=0.046), and hypertension (P=0.041). Above risk factors seemed to be clinically associated with delirium. CONSLUSION: These findings indicate that rapid infection control, maintenance of good sleep hygiene, well-controlled diabetes and hypertension, and correction of hypoxia may help to prevent delirium in general hospital's elderly inpatients.

Deletion and duplication of the -3.7-Mb region in 17p11.2 result in two reciprocal syndrome, Smith-Magenis syndrome and Potocki-Lupski syndrome. Smith-Magenis syndrome is a well-known developmental disorder. Potocki-Lupski syndrome has recently been recognized as a microduplication syndrome that is a reciprocal disease of Smith-Magenis syndrome. In this paper, we report on the clinical and cytogenetic features of two Korean patients with Smith-Magenis syndrome and Potocki-Lupski syndrome. Patient 1 (Smith-Magenis syndrome) was a 2.9-yr-old boy who showed mild dysmorphic features, aggressive behavioral problems, and developmental delay. Patient 2 (Potocki-Lupski syndrome), a 17-yr-old boy, had only intellectual disabilities and language developmental delay. We used array comparative genomic hybridization (array CGH) and found a 2.6 Mb-sized deletion and a reciprocal 2.1 Mb-sized duplication involving the 17p11.2. These regions overlapped in a 2.1 Mb size containing 11 common genes, including RAI1 and SREBF.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.

BACKGROUND: Several studies have reported that muscle strength and bone mineral density have a significant positive correlation and most previous literature on muscle strength and bone mineral density examined their association. To evaluate the association between grip strength and radius bone mineral density, more precise PQCT was used rather than SPA or DEXA. METHODS: The study was performed from June to August 1999 in Pundang community with 154 postmenopausal women who undertaken osteoporosis screening program who participated in this study. Bone mineral density was measured at the radius using PQCT (peripheral quantitive computed tomograpy). Grip and pinch strength were measured in both the dominant and nondominant hands using a dyanometer. Other data were obtained from the questionnaire. RESULTS: Grip and pinch strength of the dominant hands were significantly higher than the nondominant hands. There was no significant difference in bone mineral density by exercise and fracture history. Age-adjusted partial correlation analysis indicated a significant positive correlation of radius BMD with dominant hands grip strength. Significant positive correlations also were found between radius BMD and pinch strength. CONCLUSION: Subjects with stronger grip strength had a low BMD. There was a significant positive correlationship between bone mineral density and dominant hand grip strength. especially with the more positive association of cortical BMD with forearm circumference. The data suggest that grip strength is a weak predictor of radius bone mineral density and provide a feasible way of predicting it.
