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.

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.

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.

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.

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.

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.

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.

Intussusception is a relatively common disease in children, but it is a rare clinical entity in adults. More than 80% of all patients with intussusception are less than two years of age, but adults account for only 5 to 10 percent of all intussusception cases. The significance of this disease in the aspect of statistics is mentioned as "rule of fives", which means 5% of all intussusceptions occur in adults, and it accounts for up to 5% of all cases of bowel obstruction in adults. In children, classic symptoms include episodic abdominal pain, "current-jelly" stool and a sausage-shaped abdominal mass on examination. However, in adults, it is likely to appear with non-specific gastrointestinal trouble without classic symptoms. Therefore, it is very important to use early diagnositic tool. In contrast to childhood intussusception, which is idiopathic in 90% of cases, adult intussusception has a definable lesion in more than 90% of cases 3). Tumors, both benign and malignant, are the most frequent cause of intussusecption in adults. We experienced seven cases of adult intussusception at Inha hospital from Jan. 1994 to Dec. 1997. The patients of adult intussusception are classified as three cases of ileoileal type and four ileocecal type. There were no specific signs or symptoms with patient experienced. It included abdominal pain, diarrhea and palpable mass. Their diagnosis was made in six patients using abdominal CT scan. It is difficult to define a diagnosis preoperatively, because the symptom of adult intussusception are variable and insignificant among individuals. We had been taken the final diagnostic tool with the abdominal CT scan in six of seven patients, which revealed "target lesions" in all cases. So, it is useful in the diagnosis of adult intussusception. Bowels were resected for the treatment of adult intussusception. The extent of the resection was contained the lesion and the defunctioned segments. The operations were performed as four segmental resections of small bowel and three ileocecal resections. The pathological findings were disclosed as three tumors, three lymphadenopathies and a adhesion of bowel. We concluded that the abdominal CT scanning is a usefull diagnostic tool in the diagnosis of adult intussusception.

Stent dislogement or migration is not a rare complication. Its incidence varies from 1.4% to 8% of the cases. When stent migration occurs, the usual treatment or management is to implant stent in the distal peripheral artery or proximal coronary artery. But, probably the best treatment is safe retrieval of the dislodged stent. During the transfemoral coronary intervention, undeployed stent can be more easily retrieved into the guiding catheter with relatively larger guiding catheter luminal space. Also, larger sheath can be changed more easily when the retrieval of stent is difficult. In the transradial coronary stenting, usual size of guiding catheter is 6 Fr, makes it difficult to retrieve relatively bulky stent when deployment of stent fails. We report 2 cases of stent dislodgment during transradial coronary stenting which can be successfully removed by using myocardial biopsy forcep through 8 Fr sheath. These combination could be one of the valuable methods, especially during transradial stenting.
