PURPOSE: To evaluate the role of CT in the diagnosis of bowel and mesenteric injury we studied the CT findings and its usefulness in patients of abdominal trauma. MATERIALS AND METHODS: CT scans of 27 patients who were confirmed to have bowel and/or mesenteric injury due to abdominal trauma were analyzed retrospectively. Of these 27 patients 15 had bowel injury only and 12 had both bowel and mesenteric injury. CT findings analysed were bowel wall thickening, presence or absence of highly attenuated bowel wall, sentinel clot, mesenteric infiltration, peritoneal fluid collection and free intraabdominal air in cases with bowel injury only and with both bowel and mesenteric injury respectively. Ten patients had other accompanying abdominal injuries, such as liver, spleen, pancreas, kidney, bladder injuries, intraperitoneal abscess or retroperitoneal hemorrhage. RESULTS: Findings observed were bowel wall thickening in 23 cases(85%), peritoneal fluid collection in 21 (78%), highly attenuated bowel wall in 19(70%), mesenteric infiltration in 17(63%), free intraperitoneal air in 10 (37%) and sentinel clot in 7(26%). Pneumoperioneum were observed in 10 of 24 patients(41.7%) having bowel perforation. Two cases did not show any CT findings suggesting bowel and/or mesenteric injury. There was no significant difference in the prevalence of the CT findings between the patient group with bowel injury only and the patient group with both bowel and meseneric injury. CONCLUSION: CT scan is a useful tool in evaluating the degree and extent of bowel and/or mesenteric injury as well as in planning the patient's management.

Purpose: Hepatitis E outbreaks are a serious public health concern in the world. The pilots or air traffic controllers can be incapacitated by severe hepatitis symptoms. If the symptoms of acute hepatitis do not improve, it is not suitable for aviation duties.In this study, we compare of incidence status of hepatitis E virus (HEV) infections, and epidemic aspects between South Korea (from here on, ‘Korea’) and Japan. Methods: The raw data on confirmed of HEV infection cases were obtained from the National Notified Disease Surveillance System of Korea Diseases Control and Prevention Agency, the Ministry of Health and Welfare in Korea, and the National Epidemiological surveillance of Infectious Diseases surveillance system, administered by the National Institute of Infectious Diseases in Japan. Statistically significant differences between the epidemiological aspects and risk factors were determined using the Pearson’s chi-squared test or paired t-test. All data analyses were performed in Microsoft Excel 2010 (Microsoft, Redmond, WA, USA). Results: There were 191 cases of HEV infected cases with a prevalence rate (PR) of 0.37 per 100,000 populations of Korea in 2020. During the same year in Japan, there were 454 cases with a PR of 0.36. When compared, there is statistically none significantly differences. Moreover, both PR per 100,000 populations of HEV infections in habitat of two countries were compared, in the provinces (0.39) of Korea were much higher than that in capital city of Seoul (0.27; P<0.01), but that in Japan were capital city of Tokyo (0.84) was higher than that of the provinces (0.30; P<0.01). Male to female morbidity ratio was 1.65 and 3.78 in Korea and Japan, respectively. The distribution by the age adjusted groups were similar in Korea and Japan that the total cases occurred in the over 40-years-old age bracket, clearly showing a higher incidence in the elderly. Conclusion We believed that the HEV are a zoonotic virus, and human occurs mainly through the fecal contamination of water and consumption of contaminated meat from infected animals. In addition, HEV infection can be a problem for pilots and air traffic controllers as well, requiring further investigation and research.

Purpose: Zika virus (ZIKV) infection is a mosquito-borne Flavivirus disease. we investigated the epidemiological aspects and status of imported ZIKV infection cases in Korea (Republic of) and Japan during 2016–2020. Methods: Raw data of ZIKV infection cases from the Korea Diseases Control and Prevention Agency, and the National Institute of infectious Diseases in Japan, 2016– 2020. Results: There were 33 cases of ZIKV infection in Korea and 21 cases in Japan between 2016 and 2020. Cumulative incidence rate per 1,000,000 overseas travelers (OTs) of Korea (0.30) did not substantially differ that of Japan (0.27), respectively.We observed the ZIKV infected cases of male (69.7% of total cases) were much more than that for female (30.3%) in OTs of Korea (P<0.05). However, while there was none significant differences level between males (52.4%) and females (47.6%) in OTs of Japan. On the other hands, the distribution by adjusted-age groups for ZIKV infections were similar between Korean and Japanese that total cases occurred in the over 20 to 59-years old age, clearly more showing a higher infected of ZIKV (P<0.01). The presumptive origin imported ZIKV infection cases in Korean were as follows; Southeast Asia (81.8% of total cases) and Central & South Americas (18.2%), and those in Japan, these were Southeast Asia (42.9%) and Central & South Americas (42.9%) and Oceania (4.7%), respectively. Conclusion This study demonstrates that there is a similar pattern of imported ZIKV disease cases in Korea and Japan. Therefore, to prevent ZIKV infections, greater attention should be paid to individuals who are planning to travel to the presumptive regions of ZIKV.

It is. commonly assumed that nasorespiratory function can exert a dramatic effect upon the development of the dentofacial complex. Specially, it has been stated that chronic nasal obstruction leads to mouth breathing, which causes altered tongue and mandibular positions. If this occurs during a period of active growth, :the .outcome is development of the "adenoid facies". Such patients characteristically: manifest a vertically long lower third facial height, narrow alar bases, lip incompetence, a long and narrow maxillary arch and a greater than normal mandibular plane angle. But several authors have reported that so-called adenoid facies is not always associated with adenoids and mouth breathing, and that a particular type of dentition is not alwarys found in mouth breathers with or without adenoids. Some authors have believed adenoids lead to mouth breathing in cases with particular facial characteristics and types of dentition. We assumed that the ability to adapt to individual's neuromuscular complex is various. So, we compared the difference of influence of mouth breathing between childrens who have different facial types. This study included 60 patients and they were divided into three groups by Rickett's facial type. Their dentition and tongue position were compared. The results are as follows. 1. There is a significant difference in arch width of upper molars between different facial types. Especially dolichofacial type patients have narrowest arch width. 2. There is a significant difference in tongue position between different facial types. Especially dolichofacial type patients have lowest positioned tongue.

PURPOSE: After delivery, eating brown seaweed soup is a typical Korean tranditional habit. But, excessive intake of iodine transiently inhibits biosynthesis and secretion of thyroid hormones if a certain threshold of iodine is reached in the serum. The aim of our study was to demonstrate whether the observed the elevations of TSH level in the breast fed neonatal infants was caused by mother's eating brown seaweed soup or not. METHODS: We performed neonatal TSH test by enzyme linked immunosorbent assay(FRELISA Screenig TSH) and cheked TSH level for 178 newborns with a appropriate gestational age. We divided the study subject into 3 groups, the group used breast feeding, mother had taken brown seaweed soup and blood sampled at 6th day after birth was categorized Group A, formular feeding, blood sampled at the 4th days after birth was categorized Group B, breast feeding and had taken brown seaweed soup and blood sampled at the 19th day after birth was categorized Group C. RESULTS: 1) The mean TSH level was 1.5+/-1.3 uU/ml in Group A, 3.3+/-2.5uU/ml in Group B, 1.7+/-l.3uU/ml in Group C(Group A vs Group B: p<0.05, Group A vs Group C: p<0.05). 2) There was no statistical significances between the TSH levels and the amount of brown seaweed soup which mother had one day, the duration which mother had brown seaweed soup and duration of breast feeding. CONCLUSIONS: Mother had taken brown seaweed soup about 3 times a day in korea at present days, There was no significant changes of TSH levels in the beast fed newborn infants after the korean mother had taken brown seaweed soup.

PURPOSE: The symptoms of female urethral syndrome (FUS) can originate from mechanical or functional obstructions of the bladder neck or urethra. From retrospective reviews of women referred for evaluation of lower urinary tract symptoms (LUTS), 2.7 to 23% had urodynamic evidence of a bladder outlet obstruction (BOO). However, few urodynamic studies (UDS) have been performed on the prevalence of BOO in FUS. This study was aimed at identifying the causative factors of FUS symptoms, including BOO, as evidenced by UDS. MATERIALS AND METHODS: One hundred and sixteen women with FUS were enrolled in our UDS evaluations. An additional 247 patients, presenting for evaluation of stress urinary incontinence (SUI), served as controls. Comparisons of the maximum flow rate (Qmax), voided volume, post-void residual, detrusor pressure at maximum flow rate (PdetQmax), maximum detrusor pressure (Pdetmax) were made between the FUS and SUI cases. By definition, the FUS cases were divided into normal, BOO, detrusor under activity, detrusor instability and low compliance. These sub-groups were compared with controls in a similar way. RESULTS: Women with FUS showed a lower Qmax (15.9 versus 23.8ml/sec, p<0.05), higher post-void residual (86 versus 22ml, p<0.05), PdetQmax (24.0 versus 18.0 cmH2O, p<0.05) and Pdetmax (33.3 versus 27.9cmH2O, p<0.05) compared to those with SUI. The incidence of BOO, detrusor under activity and detrusor instability were 31.9, 25 and 16%, respectively, in the FUS group. Only 22% of women with FUS showed normal UDS findings. CONCLUSIONS: These results indicated the importance of UDS in identifying the causative factors of the symptoms of FUS. Treatment of a BOO will help provide new treatment modalities for FUS.

Transrectal Ultrasonography (TRUS) easily provides an accurate assessment of the seminal tract. In Magnetic Resonance Imaging(MRI) of the seminal tract, the anatomic relationships are more clearly seen and the multiplanar imaging is available, so a more definitive diagnosis can be achieved. Although TRUS and MRI have been studied extensively, the findings of TRUS have not been compared with those of MRI. We studied 29 patients who were assessed with TRUS and MRI simultaneously due to disease of the seminal tract. The findings of cystic disease were coincident between TRUS and MRI. But the small size Mullerian duct cysts were not found in TRUS but were found in MRI. Hemorrhage of the ejaculatory duct and seminal vesicle, thickened ampulla portion of vas deferens were found only in MRI. Ejaculatory duct and seminal vesicle calcification were not easily found in TRUS due to their small size. The findings of seminal vesicle atrophy, dilatation and prostatic calcification between TRUS and MRI were discrepant. In conclusion, MRI is more helpful than TRUS in the diagnosis of small Mullerian duct cyst, small ejaculatory duct calculi, small seminal vesicle calculi, hemorrhage of ejaculatory duct and seminal vesicle and thickened ampulla portion of vas eferens.
