BACKGROUND: Waist circumferences are widely used to diagnosis and assessment of obesity but various standards of the measuring waist circumference originate the confusion on diagnosis and assessment of obesity. According to this, this study is willing to light up standards of measuring waist circumference what is intimate with body mass index(BMI) and have a precision of intra observer and inter observers in repeated measurements of the waist. METHODS: Measuring of waist circumference by the 4 different standards(anterior superior iliac crest(ASIC), umbilicus, above 3 cm to ASIC, the thinnest area in the waist by the range of seeing) were performed on 102 people visiting Health Promotion Center of one medical collage hospital by two observers in each 2 times, total 16 times. Each data were analyzed by the relativity between the BMI and the each means of measuring waist circumference and by ANOVA test in intra observer and inter observer bias. RESULTS: The relation between BMI and data in measuring standard of ASIC of the waist circumference is the highest. (r=0.900) and the following umbilicus(r=0.896), above 3 cm to the anterior superior iliac crest(r=0.888), the thinnest area in the waist by the range of seeing(r=0.877), It is the lowest in intra observer bias that the thinnest area in the waist by the range of seeing, and ASIC in inter observer. CONCLUSION: It is desirable that ASIC is the standard of measuring waist circumference in the diagnosis of obesity and in measuring that by different two person, because of the highest relativity in BMI and the lowest inter observers bias. But the thinnest area in the waist by the range of seeing is desirable in measuring by same person because of intra observer bias.

OBJECTIVES: In the third trimester hypertensive pregnancies, we would like to evaluate effects of white coat hypertension, severity of hypertension and diurnal variation of blood pressure on the fetal outcome by using 24- hour ambulatory blood pressure monitoring. METHODS: Hypertensives(n=50) and normotensives (n=14) in the third trimester of the pregnancy underwent 24-hour ambulatory blood pressure monitoring. We excluded hypertensives(n=5) who became pre-eclampsia patients. Hypertensives(n=45) were classified as white coat hypertensives(n=14, mean ambulatory blood pressure <139/87mmHg) and sustained hypertensives(n=31). Sustained hypertensives(n=31) were divided as moderate to severe hypertensives(n=5, systolic blood pressure >160 mmHg or diastolic blood pressure >100mmHg) and mild hypertensives(n=26). Sustained hypertensives were also divided into two groups which had diurnal variation of blood pressure or not. To exclude effects of hypertension severity, effects of diurnal variation were evaluated in hypertensives with similar mean arterial blood pressure. Gestational age, body weight, body weight for gestational age were used as parameters of the fetal outcome. RESULTS: 1) The prevalence of white coat hypertension was 28%(14/50). 2) There were no significant differences in the fetal outcome between normotensives(n=14) and white coat hypertensives(n=14). 3) Body weight of fetus and body weight for gestational age in moderate to severe hypertensives(n=5) were less than those of mild hypertensives(n=26), but gestational age was not significantly different between two groups. 4) Body weight of fetus and body weight for gestational age in sustained hypertensives without diurnal variation(n=10) were less than those with diurnal variation(n=8), but gestational age was not significantly different between two groups. 5) All hypertensives who became pre-eclampsia (n=5) were severe hypertensives and had no diurnal variation of blood pressure. CONCLUSION: White coat hypertension in the third trimester was quite often and did not affect on the fetal outcome. The more severe hypertension and/or absence of diurnal variation of blood pressure caused poor fetal outcome. Patients who became pre-eclampsia were severe hypertensives and had no diurnal variation of blood pressure. Ambulatory blood pressure monitoring may have several roles in the antenatal management of hypertenison.

PURPOSE: The purpose of this study was to assess the current management status of patients with urological issues and to examine the level of knowledge and practice behaviors regarding urinary incontinence (UI) among Korean healthcare providers in long-term care hospitals. METHODS: This study used a cross-sectional descriptive design with a written questionnaire to assess knowledge and practice behaviors of 756 healthcare providers in 11 long-term care hospitals in Korean metropolitan areas. RESULTS: A total 42.6% of participants reported that more than 50% of patients had urologic issues, and that 68.1% of patients were regularly sent to urologists; no participants reported an on-site urologist in their facility. Participants identified collaboration with other hospitals and regular consultations by urologists as important factors in improving urologic care. Although the overall UI knowledge score was upper intermediate, a knowledge deficit was found for risk factors of UI. The knowledge level of physicians was significantly higher than that of other healthcare providers. Practice behaviors of nurses seemed to be better than those of other healthcare providers. CONCLUSIONS: Systematic collaboration between healthcare providers and urologic specialists, enhancing staff competence, and patient-tailored intervention should be recommended to improve quality of care for patients with urologic issues in long-term care hospitals.

PURPOSE: Stress urinary incontinence (SUI) commonly occurs in women, and it has an enormous impact on quality of life. Surgery, drugs, and exercise have been recommended for the treatment of this disease. Among these, exercise is known to be effective for the relief of symptoms of SUI; however, the efficacy and underlying mechanisms of the effect of exercise on SUI are poorly understood. We investigated the effect of swimming the symptom of SUI in relation to the expression of nerve growth factor (NGF) in rats. METHODS: Transabdominal urethrolysis was used to induce SUI, in Sprague-Dawley rats. The experimental groups were divided into the following three groups: sham-operation group, transabdominal urethrolysis-induced group, and transabdominal urethrolysis-induced and swimming group. The rats in the swimming group were forced to swim for 30 minutes once daily starting 2 weeks after SUI induction and continuing for 4 weeks. For this study, determination of abdominal leak point pressure and immunohistochemistry for NGF in the urethra and in the neuronal voiding centers (medial preoptic nucleus [MPA], ventrolateral periaqueductal gray [vlPAG], pontine micturition center [PMC], and spinal cord [L4-L5]) were performed. RESULTS: Transabdominal urethrolysis significantly reduced the abdominal leak point pressure, thereby contributing to the induction of SUI. Abdominal leak point pressure, however, was significantly improved by swimming. The expression of NGF in the urethra and in the neuronal voiding centers (MPA, vlPAG, PMC, and L4-L5) relating to micturition was enhanced by the induction of SUI. Swimming, however, significantly suppressed SUI-induced NGF expression. CONCLUSIONS: Swimming alleviated symptoms of transabdominal urethrolysis-induced SUI, as assessed by an increase in abdominal leak point pressure. The underlying mechanisms of these effects of swimming might be ascribed to the inhibitory effect of swimming on NGF expression.

BACKGROUND: The educational assessment of residents is very important in order to check their knowledge and to improve their ability. In case of family practice, the residents spend most of their training time in outside rotations with other specialities. Therefore, they are requested to be evaluated by each specialist after each rotation. To give more accurate assessment, we surveyed directly our family practice residents and family practice faculties. METHODS: A questionnaire was sent to family practice residents and family practice faculties in 116 hospitals from May to June 2006. The response rate was 29% and 78%, respectively. RESULTS: Among the total, 70.2% of family practice residents thought an assessment is necessary, but only 51.7% were evaluated. Overall, 90.4% of family practice faculties knew about the assessment of residents made by other specialists, and only 56.7% of faculties requested other specialists to assess their family practice residents. CONCLUSION: Most of the family practice residents and their faculties knew the need for assessment, but they complained there were no objectivity and the assessment tool was lacking. In order to solve this problem, it is urgent to develop a unified form and guidelines of assesment.

OBJECTIVE: To evaluate diaphragmatic motion via M-mode ultrasonography and to correlate it with pulmonary function in stroke patients. METHODS: This was a preliminary study comprised of ten stroke patients and sixteen healthy volunteers. The M-mode ultrasonographic probe was positioned in the subcostal anterior region of the abdomen for transverse scanning of the diaphragm during quiet breathing, voluntary sniffing, and deep breathing. We analyzed diaphragmatic motion and the relationship between diaphragmatic motion and pulmonary function. RESULTS: All stroke patients had restrictive pulmonary dysfunction. Compared to that exhibited by control subjects, stroke patients exhibited a significant unilateral reduction in motion on the hemiplegic side, primarily during volitional breathing. Diaphragmatic excursion in right-hemiplegic patients was reduced on both sides compared to that in control subjects. However, diaphragmatic excursion was reduced only on the left side and increased on the right side in left-hemiplegic patients compared to that in control subjects. Left diaphragmatic motion during deep breathing correlated positively with forced vital capacity (rho=0.86, p=0.007) and forced expiratory volume in 1 second (rho=0.79, p=0.021). CONCLUSION: Reductions in diaphragmatic motion and pulmonary function can occur in stroke patients. Thus, this should be assessed prior to the initiation of rehabilitation therapy, and M-mode ultrasonography can be used for this purpose. It is a non-invasive method providing quantitative information that is correlated with pulmonary function.

In this study, we tried to confirm clinically applicable applicability by comparing the difference in 3 point flexural strength and shade of the prosthesis depending on microwave sintering time of dental CAD / CAM zirconia. 3 Point flexural strength specimens (n=30) and shade measurement specimens (n=28) were prepared and sintered at different sintering times. 3 point flexural strength and shade were measured and analyzed by independent t-test (α=0.05). Measurement result of 3 point flexural strength the average of short-term sintering (STS) was 245.47±29.89 MPa, the average of long-term sintering (LTS) was 284.27±31.56 MPa, and there was a statistically significant difference (p < 0.05). The shade measurement result ⊿E*(ab) showed the average STS of 1.51±0.48 and the LTS of 1.52±0.41, but there was no statistically significant difference (p>0.05). The 3 point flexural strength of the zirconia restorations fabricated by short time and long time was high in long time sintering. However, other conditions may be required for clinical applications. Since the shade test did not show any significant color difference according to sintering time, it is considered to be sufficient for clinical application.

PURPOSE: Epstein-Barr Virus (EBV) is well understood as an oncogenic virus in human tumors. Its association with breast cancers has been reported but is still in controversy. So we have examined the expression of EBV in breast cancers and evaluated the relationship between the well-known prognositc factors of breast cancer and EBV expression. METHODS: A retrospective study was conducted with patients who had been re-evaluated to confirm the diagnosis based on immunohistochemical analysis with EBNA-2 expression, between January 1991 and December 2002. The cases were assigned to the positive lesion that displayed 10% or more of immunoreactive cells. RESULTS: The expressions of EBNA-2(Ebstein Barr virus nuclear antigen - 2) were noted in 26 (21.1%) out of 123 cases of breast cancer patients and 4 (20%) out of 20 cases in a control group of benign tumors. The expression of EBV in breast cancers and that of a control group were not different significantly. But, the correlation between the expression of EBNA-2 and ER status was noted statistically significant (P=0.040). CONCLUSION: Judging from the results of our study, EBV infection detected in breast cancer seems to be latent and the association of EBV to breast cancer is less likely related.

In females, a small evagination of parietal peritoneum accompanies the round ligament through the inguinal ring into the inguinal canal and is called the canal of Nuck; it is homologous to the process vaginalis in males. If it fails to undergo complete obliteration, an indirect inguinal hernia or a hydrocele of the canal of Nuck can occur. We report three cases of this rare developmental disorder, discuss the CT findings and its use in the diagnosis of a hydrocele of the canal of Nuck.

Small bowel hemangioma is a rare benign lesion, and it usually presents with bleeding or as a leading point of an intussusception. However, obstruction due to intramural hematoma by this lesion is unusual. Intramural hematoma of the duodenum is also an uncommon lesion, and it is usually a complication of blunt abdominal trauma in children and young adults. We present here a case of an intramural hematoma that was caused by spontaneous bleeding of a hemangioma, and this caused duodenal obstruction.
