PURPOSE: The aim of this study is that the prevalence of rotavirus infection was evaluated by each group and clinical features of group A, B and C rotaviruses infections were described respectively to compare one with another. METHODS: Between January 2010 and December 2010, we enrolled a group of children below 10 years of age admitted for management of acute diarrhea at the Catholic University of Korea Bucheon St. Mary's Hospital. A total of 310 stool samples documented to be free of common bacterial pathogens were collected from children with diarrhea. The presence of group A, B or C rotavirus is indicated by amplification of DNA segments of the expected lengths after the first and second PCRs. RESULTS: In a total of 310 stool specimens, 40 (12.9%) specimens were positive for rotaviruses. These included 23 (7.4%) positive for group A, 5 (1.6%) for group B and 12 (3.9%) for group C rotaviruses. Group B rotavirus infected patients had significantly less diarrheas per day (group A: P=0.01, group C: P=0.01) and shorter duration of vomiting days (group A: P=0.03, group C: P=0.03) than those with group A and C rotaviruses infection respectively. All the group B rotaviruses had been isolated in March and October. Group C rotavirus infections were prevalent during late summer and early winter and peaked in October. CONCLUSION: These findings indicate that group B and C rotaviruses are notable causes or the contributing causes of diarrhea among infants and children in Korea.

Purpose:
To investigate the clinical results of vitrectomy alone as the primary treatment for rhegmatogenous retinal detachment (RD) in patients with atopic dermatitis (AD).
Methods:
The medical records of patients with AD treated for rhegmatogenous retinal detachment (RD) were retrospectively reviewed. We investigated the characteristics of retinal breaks and detachments, applied surgical methods, and results.
Results:
Twenty eyes of 14 patients with AD who presented with rhegmatogenous RD and treated by vitrectomy were included in this analysis. Sixteen eyes (80%) were treated with vitrectomy, either alone or in combination with cataract surgery, and the retina was successfully attached to 94% of the eyes. There were four cases in which vitrectomy was combined with encircling. Reoperation was needed in half of the eyes that received vitrectomy with encircling, which presented nearly total detachment, severe proliferative vitreoretinopathy, and pseudophakia.
Conclusions
Vitrectomy alone, in combination with cataract surgery, may be sufficient to treat rhegmatogenous RD in patients with AD. Additional encircling or buckling should still be considered in complicated cases.

OBJECTIVES:
Construction workers face an elevated risk for several types of cancer. Nevertheless, there is a lack of large-scale epidemiological studies examining the risk of all cancers in construction workers. This study aimed to investigate the risk of various cancers in male construction workers using the Korean National Health Insurance Service (NHIS) database.
METHODS:
We used data from the NHIS database from 2009 to 2015. Construction workers were identified using the Korean Standard Industrial Classification code. We calculated the age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for cancer occurrence in male construction workers compared to all male workers.
RESULTS:
Compared to all male workers, the SIRs for esophageal cancer (SIR, 1.24; 95% CI, 1.07 to 1.42) and malignant neoplasms of the liver and intrahepatic bile ducts (SIR, 1.18; 95% CI, 1.13 to 1.24) were significantly higher in male construction workers. The SIRs for malignant neoplasms of the urinary tract (SIR, 1.19; 95% CI, 1.05 to 1.35) and non-Hodgkin lymphoma (SIR, 1.21; 95% CI, 1.02 to 1.43) were significantly elevated in building construction workers. The SIR for malignant neoplasms of the trachea, bronchus, and lung (SIR, 1.16; 95% CI, 1.03 to 1.29) was significantly higher in heavy and civil engineering workers.
CONCLUSIONS
Male construction workers have an increased risk for esophageal cancer, liver cancer, lung cancer, and non-Hodgkin’s cancer. Our results indicate that tailored strategies for cancer prevention should be developed for construction workers.

PURPOSE: To compare the effects of anti-inflammatory agents, specifically bromfenac, loteprednol, and prednisolone, on the permeability of cultured human trabecular meshwork cell (HTMC) monolayers. METHODS: HTMCs were cultured until confluency in the inner chamber of Transwell, then exposed to 1/1,000 or 1/500 diluted commercial 0.1% bromfenac, 0.5% loteprednol, and 1% prednisolone for 24 hours. The permeabilities of carboxyfluorescein through the HTMC monolayer were measured with a spectrofluorometer after 2 hours in the outer chamber. Cellular viabilities were assessed with an 3-[4,5–dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. RESULTS: Bromfenac and loteprednol diluted at 1/1,000 or 1/500 did not significantly affect the cellular survival (p > 0.05). Bromfenac did not affect the permeability via the HTMC monolayer (p > 0.05) and loteprednol decreased the permeability (p < 0.05). In addition, 1/2,000 prednisolone also decreased the permeability (p < 0.05). CONCLUSIONS: Among the anti-inflammatory agents, the non-steroidal anti-inflammatory agent bromfenac did not affect the permeability, while loteprednol and prednisolone decreased the permeability through the HTMC monolayer. Thus, loteprednol and prednisolone may decrease the trabecular outflow.

Background:
The purpose of this study is to explain the factors influencing the incurrence of catastrophic health expenditure of national health insurance households using panel data observed over a long period.
Methods:
The study targeted 3,652 households who had no censoring during the 11-year survey period (2007–2017) and householders whose insurance type was consistently maintained as national health insurance. Generalized estimating equations were adopted to identify factors affecting the occurrence of catastrophic health expenditure at 20%, 30%, and 40% threshold levels. A subgroup analysis was conducted by categorizing groups depending on the existence of the elderly in the household.
Results:
For the last 11 years, the incidence of catastrophic health expenditure in the households without the elderly decreased slightly at all threshold levels, but the households with the elderly seemed to be increased. At baseline, household type showed a statistically significant relationship with all other variables. The results of generalized estimating equations analyses show that household income was not significant at all threshold levels in the households without elderly. On the other hand, in the households with the elderly, the 2nd (odds ratio [OR], 1.33–2.05) and 3rd quintile groups (OR, 1.25–2.55) were more likely to have catastrophic health expenditure compared to the 1st quintile of household income group.
Conclusion
As the amount of health expenditures relative to the ability to pay is increasing in households with the elderly, the application of an intervention followed by consistent monitoring is needed. This study found that there were differences in influencing factors according to the presence of the elderly in the households. In particular, in households with the elderly, interesting results have been drawn regarding the occurrence of catastrophic health expenditure in the near-poor, so additional research is required.

Epidural blood patch is an effective management for treatment of severe post-dural puncture headache. Here we describe a case of a patient with hip fracture, who was complained regarded as having suspicious post-dural puncture headache after epidural anesthesia, but it failed to be treated with 4 times of epidural blood patch, and later was diagnosed with multiple metastatic brain tumor.
