PURPOSE: In order to assess the incidence and radiologic findings of herniation pit of the femur neck in Korean. IVlaterials and Methods:In 152 macerated femurs of 88 cadavers, and randomly selected 115 hips of 70 patients, the presence of herniation pit was determi ned by using fluoroscopy and radiography. It was then examined by CT for inspection of overlying surface and its opening was confirmed by inserting thin steal wire under the fluoroscopic guidance. RESULTS: Seventeen herniation pits in 15 macerated femurs of 13 cadavers were noted. (14.8%, 13/88). Two of 13 individuals showed bilaterality. All lesions were found only in males. Six herniation pit in 6 femurs of 6 patients (8.6%, 6/70) were also noted. All lesions were on anterosuperior aspect of. femur neck. Plain radiographs of macerated femurs revealed well marginated and thin sclerosis in 15 lesions. Of all 23 lesions, CTshowed cortical breakdown in 3, and overlying cortical thickening in 8. In 15 macerated femurs, roughed area of cortex was found in anterosuperior aspect of femur in all cases, and tiny openings(diameter less than 1 mm) related to cystic lesions were confirmed in 9 lesions. CONCLUSION: The incidence of herniation pits was 14.8% in 88 cadaver, and 8.6% in 70 patients. All were males.

The purpose of this study were to find out the practical way to enlarged child-raising knowledge and to enhance their satisfaction with out-patient care by evaluating how effectively the education is done by nurses for mothers with ill-child and how their satisfaction with out-patient care changed. This study was designed as a Nonequivalent Control Group study. The subjects studied were consisted of the experimental and control group. Each consisted of 50 mothers with ill-child in pediatric department at one university hospital in Seoul. The period of this study is from May 20, 1996 to June 28, 1996. The first data were collected fro both of experimental and control groups in which mothers with ill-child come to the hospital for the first time. After this being done, the experimental group had been educated by the planned program and then the second data were collected from them. On the contrary, as for the control group, there had been no education and the second data were collected on the same method. The data analysis was done by SPSS program. The results of this study are as follow, 1. The child-raising knowledge level of mothers with education was higher than that of with no education.(t=18.84, df=49, p=0.000) 2. The satisfaction with out-patient care level of mothers with education was higher than that of no education.(t=10.51, df=49, p=0.000) Based on these results, I suggest as follow, 1. The research on the patients and their family should be made not only in pediatric department, but in every out-patient department. 2. For more effective education, it is required for all out-patient nurses to research the education demand of patients and their family. 3. To increase the effect of education, there must be the consultation room in out-patient department. 4. The meetings with the mothers with ill-child of the same illness have to be established and periodical education must be executed. 5. Audio-visual education programs like video tapes are needed to make use of waiting time for the medical treatment. 6. On-line consulting program are needed.

INTRODUCTION: Although it is well known that medical students are not getting an adequate amount of sleep, there have been only few studies on the sleep patterns of medical students in Korea. Therefore, the present study aimed to investigate the life style and sleep patterns of Korean medical students and the impact they have on the students' academic performance. METHODS: A questionnaire package was administered to the 3rd year medical students at the Seoul National University to examine their sleep patterns on weekdays and weekends. It consisted of questions asking about their lifestyles as well as Pittsburgh sleep quality index (PSQI) and GPA (Grade Point Average) that are considered relevant to their sleep patterns. A total of 110 students (85 males and 25 females, mean age 24.4+/-20.6) responded to the survey and the result was analyzed using the independent t-test, the chi-square test, the paired t-test, Pearson's rank correlation and ANOVA. P-values of less than 0.05 were considered statistically significant in all analyses. RESULTS: The weekend bedtime was significantly delayed (01:24 on weekday; 03:12 on weekend; t=-5.23, p<0.01), the weekend rise time was delayed (07:36 on weekday; 10:30 on weekend; t=-24.48, p<0.01) and the total sleep time was increased on weekends (5:57 on weekday; 8:17 on weekend; t=15.94, p<0.01). They wished to sleep for 7 hours 6 minutes which was different from their actual weekday total sleep time (t=-11.41, p<0.01). The poor sleeper group had lower GPAs than the good sleeper group (t=2.05, p<0.05). The GPA of medical students were negatively correlated with age (r=-0.23, p<0.05), daily amount of smoking (r=-0.78, p<0.01), total amount of smoking (r=-0.75, p<0.01), weekday sleep latency (r=-0.23, p<0.05), weekend sleep latency (r=-0.23, p<0.05) and PSQI score (r=-0.30, p<0.01). CONCLUSION: Medical students were experiencing a lack of sleep during weekdays as they have a later bedtime and earlier rise time, and consequently had more hours of sleep on weekends. Overall, the responded students were experiencing poor sleep quality, and the GPAs of the poor sleeper group were lower than those of the good sleeper group.

Bcl-2 is a proto-oncogene initially described in follicular lymphoma, associated with chromosomal translocation(14;18). Recent studies have shown the presence of Bcl-2 in nonhematolymphoid tissue, especially in hormonally responsive tissue. The endometrium is an attractive model for studying the hormone dependent regulation of Bcl-2 expression. We have studied the immunoreactivity of Bcl-2 oncoprotein in relation to the immunoreactivity of estrogen receptors(ER) and progesterone receptors(PR) by immunohistochemistry in 52 human endometrial carcinomas, according to nuclear grade. The results obtained are summarized as followings, 1) Immunohistochemical grade of Bcl-2 showed a significant inverse correlation with nuclear grade. 2) Immunohistochemical grades of ER and PR also showed a significant inverse correlation with nuclear grade, and were well correlated with each other. 3) Immunohistochemical grades of Bcl-2 and hormone receptors showed a strongly significant correlation. On the basis of the above results, we suggest that Bcl-2 expression may be under hormone dependent control and that it can be used in prognosis and choice of hormonal therapy in the presence of hormone receptor.

We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.

PURPOSE: The objective of this study was to assess and investigate the epidemiology of pertussis in infants under 6 months of age. METHODS: A prospective study was conducted between October 1, 2011 and April 30, 2013 in CHA Bundang Medical Center, Seongnam, South Korea. Polymerase chain reaction (PCR) or culture was used to detect Bordetella pertussis in nasopharyngeal aspirates from case patients who were hospitalized for acute lower respiratory tract infection (LRTI). In addition, multiplex real-time PCR assays were also performed to detect 6 etiologic viruses, including adenovirus, human metapeumovirus, influenza virus, parainfluenza virus, respiratory syncytial virus and rhinovirus. RESULTS: Of the 79 enrolled case patients, whose median age was 2 months of age, the most common diagnoses uncovered in this study were acute bronchiolitis (60%) and pneumonia (28%). B. pertussis infection was found in 13 cases (16%), in which 7 (53%) was coinfected with respiratory syncytial virus and 1 (7%) with influenza A virus. Of the 13 patients with B. pertussis infection, 6 (46%) were not vaccinated with the diphtheria, tetanus toxoid, and acellular pertussis vaccine, while 6 (46%) received 1 dose, and 1 (8%) received 2 doses. CONCLUSION: B. pertussis infection was present in 16% of under 6 month-old infants, who were hospitalized for acute LRTI. Therefore, a nationwide epidemiological surveillance of pertussis, including institutions that cater to infants under 6 months of age is necessary and needed.

The authors defined precaval retropancreatic space as the space between pancreatic head with portal vein and IVC analyzed the CT findings of this space to know the normal structures and size in this space, We evaluated 100 cases of normal anbdominal CT scan to find out normal anatomic structures of precaval retropancreatic space retrospectively. We also measured the distance between these structures and calculated the minimum, maximum and mean values. At the splenoportal confluence level, normal structures between portal vein and IVC were vessel (21%), lymph node (19%), and caudate lobe of liver (2%) in order of frequency. The maximum AP diameter of portocaval lymph node was 4mm. Common bile duct(CBD) was seen in 44% and the diameter was mean 3mm and maximum 11mm. CBD was located in extrapancreatic (75%) and lateral (60.6%0 to pancreatic head. At IVC-left renal vein level, the maximum distance between CBD and IVC was 5mm and the structure between posterior pancreatic surface and IVC was only fat tissue. Knowledge of these normal structures and measurement will be helpful in differentiating pancreatic mass with retropancreatic mass such as lymphadenopathy.
