The aim of this study was to examine the factors influencing perceived oral health in elderly individuals residing in the community.

Paralytic hand is the ultimate result of permsnent damage of the central nervous system, failure of the functional repair of peripheral nerve injuries and extensive muscular or tendinous defect resulting in the impairment of hand function. There are a lot of controversies in the side of treatment methods in the paralytic hand, and it is very difficult to formulate the most adequate surgical reconstruction for a given pstient. At Depsrtment of Orthopedic Surgery, Seoul National University Hospital, 66 cases oi paralytic hands in 62 patients have been treated surgically with tendon transfers for 7 years from Jan, 1980 to Dec, 1986. 49 case in 46 patients were followed up for more than one year, and surgical method and its results were anslysed. They consist of CNS lesion (17), peripheral nerve lesion(23) and musulotenidinous defect(9). The methods of surgical reconstruction were opponenesplasty(12), standard set extensor reconstruction(9), Green and Bsnks FCU transfer(11), intrinsic reconstruction(7), pronator rerouting(7), adductorplasty (5) and so on. The mean follow-up was 2.2 years, and in 38 cases good or excellent results were obtained.

PURPOSE:To evaluate the role of unenhanced CT in diagnosing the acute appendicitis. METHOD AND MATERIALS: We retrospectively analyzed conventional contrast-enhanced abdominal CT scans of 197 normal patients and barium enemas of 26 out of the 197 patients. Additional unenhanced CT scans of right lower abdomen were performed on 30 patients who were suspected of having acute appendicitis;barium enema was performed in 26 patients. RESULTS: in the analysis of the conventional CT scans, we could detect 132(67%) normal appendicies. On barium enema of 26 out of 197 patients, abruptly narrowed appendix was visualized in 5 cases and luminal irregularity in 4 cases but all 26 cases showed normal appendix on CT. In the 30 cases of unenhanced CT, all appendicies were visualized. Among 12 Cases which were proved as acute appendicitis, barium enenma was done in 10 case;abruptly narrowed appendix was shown in 3 and luminal irregularity in 1. Among 18 cases which were diagnosed as normal appendix, nonvisualization of appendix' was in 1 case, abruptly narrowed lumen in 3, and luminal irregularity in 9. CONCLUSION:Unenhanced CT in the area of the cecum may be an effective and safe diagnostic tool for acute appendicitis.

PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

Thyroid cancer is not only an infrequent cancer, but also is the most common malignancy of the endocrine system. When thyroid cancer occurs in childhood and adolescence, it is an unusual but interesting malignancy. Thyroid cancer in childhood and adolescence has a slightly lower preference for female than for male subjects, as compared to adult patients. With regard to the pathogenesis the only factor definitely known to promote development of thyroid cancer in the pediatric age group is irradiation. The evidence demonstrates that thyroid carcinoma in the pediatric age group is a biologically self-reliant and more hostile nature than in adults but paradoxically the prognosis is good. Enhanced survival resulting from advances in therapy in patients with Hodgkin's disease is associated with long-term morbidity, including the potential for the development of a second solid malignancy. Second malignant neoplasms(SMNs) have become a principal consideration in evaluating the prolonged consequences of strategy in pediatric oncology. Thyroid carcinoma has proven to be a common SMN. We have experienced 2 cases of papillary thyroid cancer following radiation therapy for Hodgkin's lymphoma and a papillary thyroid cancer with pulmonary metastases.

This study was performed to determine the effects of nitric oxide on human sperm cell function. Semen samples were obtained from normal healthy volunteers. Motile spermatozoas collected by swim-up method were incubated up to 24 hours in Ham's F-10 medium supplemented with a various concentration of sodium nitroprusside (nitric oxide releasing agent). Sperm motility, hyperactivation, acrosome reaction rate, and acrosin activity were determined. The results are as follows; 1. 1mM of SNP resulted in a significant decrease in sperm motility (44.8%+/- 8.9%:78.1%+/-6.3%, and hyperactivation (10.4%+/-6.4%:477%+/-9.5%) after incubation for 3 hours compared with the control group (Ham's F-10 alone), but had no effect on acrosome reaction. 2. At 100muM SNP, sperm motility was reduced after incubation for 6 hours (54.8%+/- 3.2%) compared with that of the control group (82.7% +/- 8.9%), but hyperactivation and acrosome reaction were not affected. 3. However, a lower concentration (less than 101M) of SNP had no effect on sperm motility and hyperactivation for 8 hours of incubation but significantly decreased them when incubation periods were increased up to 24 hours compared with the control group. On the other hand, 1muM and l0muM SNP significantly increased the acrosome reaction rate in both acrosomal status (17.3%+/-5.2%,23.5%+/-4.7%, respectively) and acrosin activity (34.3muIU+/- 10.5muIU, 45.6muIU+/-5.6muIU, respectively) as compared with the control group (7.0%+/-4.0%, 9.5muIU+/-3.4muIU). These results indicate that SNP, NO releasing agent, has a dose-dependent effects on the sperm cell function. Therefore it may positively affect the fertilization by promoting acrosomal reaction at a lower concentration (less than 101M).

Inflammatory pseudotumor, originally described in the lung, is a relatively rare tumor-like lesion that occurs in various organs and tissues. It is usually well demarcated from the surrounding tissue, however it can be unfortunately resected as a malignant tumor. A few inflammtory pseudotumor in the kidney have been reported in English literature, but there have been no reports in Korea. We report a case with inflammatory pseudotumor of the kidney. A 48 year old woman had an intermittent flank pain on the right side. An ultrasonographic study suggested a renal cell carcinoma and a nephrectomy was done. Grossly, there were two separate masses with a well demarcated yellowish appearance, measuring 2.3 cm and 1.3 cm in diameter, respectively. Histologically, they were composed of smooth muscle actin positive spindle cells and a large number of foamy histiocytes, lymphocytes, and plasma cells in the fibrotic backgound.

The association between choledochal cysts and pregnancy is unlikely to be etiological, but may rather be an aggravation or precipitation of a preexisting condition. Although choledochal cysts rarely occur in pregnancy, the aim of this study is to elucidate the condition associated with pregnancy because delayed or inappropriate therapy may be catastrophic for both mother and child. Authors reviewed 18 cases of choledochal cyst, of which 2 were aggravated during pregnancy, managed at the Department of Surgery, Hangang Sacred Heart Hospital, College of Medicine, Hallym University, during the period from 1990 to 1995. The results were as follows: The ratio of female to male was 2.6:1 which revealed predominance in female and most frequent age group was above sixty years old(33%). In non-pregnant patients, the most common symptoms were abdominal pain(78%) and all pregnant patients had pain, jaundice, nausea and vomiting, and indigestion. Transaminase and bilirubin were elevated in all pregnant patients. In all patients, US(88%, 100%) was the most common preoperative diagnostic study and one case was diagnosed during explo-laparotomy. Pregnant patients have cholecystitis in two cases and nonpregnant patients had cholecystitis(19%), CBD stone(19%), and others. The operative procedures were performed in 9 cases and pregnant patients were operated by cyst excision and Roux-en-Y hepaticojejunostomy in one case, and also Roux-en-Y choledochocystojejunostomy in one case. According to Todani's classification, in non pregnant patients, type I was the most common(63%), in pregnant patients, two cases were type I. Postoperative complications occurred in 3 cases, wound infection(6%) and cholangitis(6%) in non pregnant patients, pleural effusion(6%) in pregnant patients. Two cases of choledochal cyst in pregnancy were 25 years old at 29.4 weeks and 36 years old at 16 weeks into pregnancy.

A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is unique in that there was a latent period between infusion and development of PRES. We postulate that rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We suggest that neurological symptoms after blood transfusion should be appropriately investigated.

This study was conducted to evaluate the effect of PTSD on memory funtion and hippocampal volume, and to identify major variables correlated to hippocampal volume and memory function. Thirty four Vietnam veterans were collected for this study, among whom eighteen were PTSD patients and sixteen were combat control subjects. The author used Impact of Event Scale(IES), Combat Exposure Scale(CES), Hamilton Depression Rating Scale(HDRS) and Beck Depression Inventory(BDI). Korea Memory Assessment Scale(K-MAS) was assessed for memory function. Magnetic resonance imaging(MRI) was used to measure hippocampal volume. There were significant differences between PTSD and Non-PTSD veterans in IES, HDRS and BDI. Significant difference was found in verbal memory and total memory of K-MAS between PTSD and Non-PTSD veterans. There was significant difference in hippocampal volume between PTSD and Non-PTSD veterans. Short term memory, verbal memory and total memory were positively correlated to hippocampal volume. Hippocampal volume was negatively correlated to IES, HDRS, and BDI. These results suggest that PTSD severity be associated with hippocampal atrophy and memory dysfunction. Reduced or smaller hippocampal volume may be preexisting risk factor for stress exposure or the development of PTSD on combat exposure.
