Objective: Previous studies have reported the presence of a “weekend effect” with respect to mortality in serious emergency admissions, including cases of traumatic brain injury (TBI).However, the relationship between weekend hospitalization and TBI mortality has not been fully established. This study aimed to conduct a systematic review of available evidence and investigate differences in mortality among TBI patients between weekday and weekend admissions. Methods: Electronic databases including PubMed, Cochrane Library, and Embase were used to obtain relevant articles. Mortality, as the primary outcome of interest, encompassed inhospital or 30-day mortality. Mortality rates were compared between the 2 groups, weekend and weekday admissions. Additionally, meta-regression analysis was performed on potential confounders to verify and provide comparative results. Results: A total of 7 studies involving 522,942 TBI patients were eligible for inclusion in the synthesis of the systematic review. Of these patients, 71.6% were admitted during weekdays, whereas 28.4% were hospitalized on weekends. The overall integrated mortality was 11.0% (57,286/522,942), with a mortality rate of 10.8% in the weekday group and 11.3% in the weekend group. Pooled analysis revealed no significant difference in mortality between the weekday and weekend groups (risk ratio, 0.99; 95% confidence interval, 0.90–1.09; p=0.78).Furthermore, the meta-regression analysis for sensitivity assessment showed no modifying effect on mortality (p=0.79). Conclusion This study found no difference in mortality rates between weekday and weekend admissions among TBI patients. Additional sensitivity analyses also demonstrated no significant increase in the risk of mortality in the weekend group.

Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.

Suicide is becoming a public health issue in many countries, and even more so in Korea. Korea has the highest suicide rate in the Organization for Economic Cooperation and Development countries. To address these issues, we investigated the recent trends in suicidal ideation and suicide attempts among the adult population. We used data from four sources: Korean National Health and Nutrition Examination Survey (KNHANES, ‘2007–2012, ‘2013, ‘2015), Korean Community Health Survey (KCHS, ‘2008–2009, ‘2013), Korean Wealth Panel Study (KOWEPS, ‘2012–2015), and Korea Health Panel Survey (KHP, ‘2010–2013). Weighted frequencies and trend tests were used. The rate of suicidal ideation as recent year was 5.10% (KNHANES, ‘2015), 8.95% (KCHS, ‘2013), 2.34% (KOWEPS, ‘2015), or 5.39% (KHP, ‘2013). Regarding the suicide attempts, the rate of suicide attempts as recent year was 0.61% (KNHANES, ‘2015), 0.41% (KCHS, ‘2013), or 0.04% (KOWEPS, ‘2015). Average percent change of suicidal ideation during survey year was -2.80% (KNHANES, ‘2007–2012), 5.78% (KNHANES, ‘2013–2015), 0.62% (KCHS, ‘2008–2013), -5.63% (KOWEPS, ‘2012–2015), and -10.94% (KHP, ‘2010–2013). Average percent change of suicide attempts during survey year was -3.84% (KNHANES, ‘2007–2012), 4.55% (KNHANES, ‘2013–2015), -2.54% (KCHS, ‘2008–2013), and -18.96% (KOWEPS, ‘2012–2015). Those who had lower income level were more likely to have self-reported suicidal ideation and suicide attempts. Our results suggest that further efforts are needed for more effective intervention to identify and manage low income strata with suicide problem.

The transverse sacral fracture is rare; however, if it accompanies neurological injury or instability, difficult surgical treatment may be necessary. We performed surgical decompression and laminoplasty in a patient with neurological deficits and anterior displacement of S2 on S1. The patient showed a successful clinical outcome by neurological improvement.

Human papillomavirus(HPV) has implicated in the development of cervical cancer. Several studies has suggested a strong correlation between HPV 16, 18 and cervical intraepithelial neoplasia(CIN). For detecting and typing HPV DNA in cervical tissues, recently the chemiluminescent molecular hybridization assay method has been widely used. This study was performed to determine the usefulness of hybrid capture assay for detecting high-risk HPV in cervical epithelial cells, and to compare the correlation among cervical cytology, biopsy finding and HPV infection, and to determine whether the addition of the hybrid capture assay to cytologic test would improve the ability to identify significant lesions. This study included 267 patients who visited the colposcopic clinic of the department of obstetrics and gynecology, Chonbuk University Hospital from May, 1997 to October 199S. Pap smears hybrid capture assays, and colposcopically directed biopsy were performed concurrently on al1 women. The results obtained were as follow; l. Using hybrid capture assay, the detection rate of high-risk HPV of all patients was 37.1%(99/267). There was no statistical significance in the detection rate of HPV between the age groups. 2. The false negative rate of Pap Smear was 53.3% and showed significant discrepancies between the cytologic and histologic diagnosis. 3. According to the cytologic diagnosis, the detection rates of high-risk HPV were 7.1% in normal, 25.3% in ASCUS or LSIL, and 61.6% in HSIL. In each cytologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 4. According to the histologic diagnosis, the detection rates of high-risk HPV were 0.1% in normal, 11.1% in CIN I, and 72.7% in CIN II or CIN III. In each histologic group, the patients who had positive results for high-risk HPV showed higher incidence rate of high grade lesions than those with negative results(P<0.05). 5. According to the comparison of histologic diagnosis between positive and negative results of high-risk HPV test due to each cytology, there was no statistical significance in the incidence rate of cervical neoplasia, Above results suggest that high-risk HPV test using hybrid capture assay may be a useful method in supplement the pitfalls of cervical cytology. This test might also have prognostic value in the management of patients with CIN.

The aquatic quality of the Naktong river after two of three months in June, 1991 with phenol spillage from a electrical factory in Kumi was investigated. The samples were collected at six sites of the Naktong river basin and Kachang and Kongsan lakes. Phenol was not detected from all water samples. Turbidity was very much increased to the down stream in the Naktong river. The BOD and COD values exceeded the 2nd grade(3 mg/l) of the Korean standard quality of Environmental Water Act at the all sampling sites of the Naktong river. Especially, the value of COD at Kaejin (12.5 mg/l) was poorly classified as to the 5th grade of water class for the environmental quality standards. Organophosphorous pesticides such as parathion, malathion, fenitrothion and diazinon were investigated but not detected. Diazinon was only detected at the Ilson bridge(1.42 ppb), Okkye stream(6.95 ppb), Waekwan bridge(0.32 ppb), Gangjung reservior(0.13 ppb), Kaejin(0.05 ppb). Of the carbamates such as carbanyl, isoprocarb and cabofuran, the carbofuran was detected all sites except tap water, and Kachang and Kongsan lakes. The content of heavy metals such ans Cd, Pb, Zn, Fe, Mn, Hg were not exceeding for drinking water standards at the all sampling region, but only mecury was detected from Okkye stream(0.018ppb) and Kaejin(0.09ppb). In the regions of Kachang and Kongsan lakes, the content of heavy metals were lower than that of reservoir of Naktong river.
