Hearing loss in newborns is the most frequently occurring birth defect. If hearing impaired children are not identified and managed early, it is difficult for many of them to acquire the fundamental language, social and cognitive skills that provide the foundation for later schooling and success in society. All newborns, both high and low risk, should be screened for hearing loss in the birth hospital prior discharge (Universal Newborn Heaing Screening, UNHS). Objective physiologic measures must be used to detect newborns and very young infants with hearing loss. Recent technological developments have produced screening methods and both evoked otoacoustic emission (EOAE) and auditory brainstem response (ABR) have been successfully implemented for UNHS. Audiologic evaluation should be carried out before 3 months of age and infants with confirmed hearing loss should receive intervention before 6 months of age. All infants who pass newborn hearing screening but who have risk indicators for other auditory disorders and/or speech and language delay receive ongoing audiologic surveillance and monitoring for communication development. Infants with sensorineural hearing loss are managed with hearing aids and receive auditory and speech-language rehabilitation therapies. Cochlear implants can be an outstanding option for certain children aged 12 months and older with severe to profound hearing loss who show limited benefit from conventional amplifications.

Purpose: The purpose of this study was to identify trends in health-related interventions on children attending Community Child Care (CCC) centers, which are part of a health policy to provide after-school care for vulnerable children in South Korea. Methods: From 2007, 109 papers were analyzed using the scoping study method. Results: The number of studies increased steadily between 2007 and 2016. Most studies were based on the social sciences, and the participants were mainly elementary school students. Psychological and social interventions were the most common types of interventions with socio-psychological indicators as measurements. In addition, only a few studies had a clearly defined conceptual framework. The majority of studies did not explicitly indicate that they followed ethical considerations. Conclusion: It is necessary to develop health-related interventions for children attending CCC centers using diverse subjects, types, and evaluation methods, along with improvements in the quality of research methodology. Furthermore, it is essential to clearly articulate and implement ethical considerations in research targeting vulnerable children.

Background: The purpose of this study was to evaluate the risk factors for mechanical ventilation in the patients with scrub typhus admitted to intensive care unit (ICU) at a university hospital. Methods: We retrospectively selected and analyzed clinical data from the medical records of 70 patients (32 men, 38 women) admitted to the ICU with scrub typhus between 2004 and 2014. The patients had a mean${\pm}$standard deviation age of $71.2{\pm}11.1years$ and were evaluated in two groups: those who had been treated with mechanical ventilation (the MV group, n=19) and those who had not (the non-MV group, n=51). Mean ages of the MV group and the non-MV group were $71.2{\pm}8.3years$ and $71.2{\pm}11.1years$, respectively. Results: Significant differences between the two groups were observed with respect to acute respiratory failure (p=0.008), Acute Physiology and Chronic Health Evaluation (APACHE) II score (p=0.015), Sequential Organ Failure Assessment (SOFA) score (p=0.013), death (p=0.014), and ICU duration (p<0.01). Multivariate analysis indicated that the following factors were significantly associated with mechanical ventilation: acute respiratory failure (p=0.011), SOFA score (p=0.005), APACHE II score (p=0.011), platelet count (p=0.009), and lactate dehydrogenase (LDH) (p=0.011). Conclusion: Thus, five factors-acute respiratory failure, SOFA score, APACHE II score, platelet count, and LDH-can be the meaningful indicators for mechanical ventilation for the patients with scrub typhus admitted to ICU.

Toxoplasma gondii is an important opportunistic pathogen that causes toxoplasmosis, which has very few therapeutic treatment options. The most effective therapy is a combination of pyrimethamine and sulfadiazine; however, their utility is limited because of drug toxicity and serious side effects. For these reasons, new drugs with lower toxicity are urgently needed. In this study, the compound, (Z)-1-[(5-nitrofuran-2-yl)methyleneamino]-imidazolidine-2,4-dione (nitrofurantoin), showed anti-T. gondii effects in vitro and in vivo. In HeLa cells, the selectivity of nitrofurantoin was 2.3, which was greater than that of pyrimethamine (0.9). In T. gondii-infected female ICR mice, the inhibition rate of T. gondii growth in the peritoneal cavity was 44.7% compared to the negative control group after 4-day treatment with 100 mg/kg of nitrofurantoin. In addition, hematology indicators showed that T. gondii infection-induced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, biochemical parameters involved in liver injury, were reduced by nitrofurantoin significantly. Moreover, nitrofurantoin exerted significant effects on the index of antioxidant status, i.e., malondialdehyde (MDA) and glutathione (GSH). The nitrofurantoin-treated group inhibited the T. gondii-induced MDA levels while alleviating the decrease in GSH levels. Thus, nitrofurantoin is a potential anti-T. gondii candidate for clinical application.

연구배경: 폐 비결핵항산균증은 최근 빈도가 급증하고 있으며 이에 따라 그 진단과 치료에 있어서 많은 변화와 발전이 이루어지고 있다. 최근의 증례 증가에도 불구하고 이에 대한 국내 임상연구는 매우 드문 실정이어서 본 연구를 시행하였다. 방 법: 1990년 1월부터 1998년 8월까지 서울대병원에서 검사한 호흡기검체에서 비결핵항산균이 배양되었던 57예 중 1997년 개정된 미국 흉부학회 진단기준에 적합한 27예를 대상으로 임상상, 방사선소견, 치료 및 임상경과를 후향적으로 분석하였다. 결 과: 남자 15명, 여자 12명이였고 평균연령은 51.5세였다. 20명(74.1%)에서 선행 폐질환이 있었고 이 중 19명(70.4%)은 폐결핵의 기왕력이 있었다. 방사선 소견상 16명(59.2%)에서 공동이 있었고, 추적관찰시 대부분에서 1년이상에 걸쳐 서서히 변화하는 양상을 보였다. 항결핵제에 대한 감수성검사상 INH 100%, RMP 72.2%, EMB 81.5%, PZA 92.6%의 내성율을 보였고, 2차 항결핵제에 대해서도 평균 66.1%의 높은 내성율을 보였다. 약물치료는 21명(77.8%)에서 시행되었고 11명은 호전, 10명은 악화되었다. 치료하지 않은 6명(22.2%)은 1명만이 호전, 5명은 악화되었다. 임상경과에 영향을 미치는 요인을 분석하였을 때 공동이 있거나 사용된 감수성 약제수가 3제미만인 경우 치료반응이 유의하게 나빴다. 결 론: 우리나라의 폐 비결핵항산균증은 최근 증가하고 있으며 선행 폐질환이 있는 중년이상의 환자에서 많이 발생하고 선행 폐질환으로는 과거의 결핵병변이 압도적으로 많다. 기존의 항결핵제로는 치료성적이 좋지 않으므로 새로운 약제를 중심으로 하는 감수성검사와 이에 따른 치료약제의 변화가 시급히 필요하리라 생각된다. 또한, 앞으로 많은 수의 환자를 대상으로 하는 임상연구를 통하여 우리나라자체의 진단과 치료지침이 세워져야 할 것이다.

China still has more than 30,000 patients of advanced schistosomiasis while new cases being reported consistently. D-dimer is a fibrin degradation product. As ascites being the dominating symptom in advanced schistosomiasis, the present study aimed to explore a prediction model of ascites with D-dimer and other clinical easy-achievable indicators. A case-control study nested in a prospective cohort was conducted in schistosomiasis-endemic area of southern China. A total of 291 patients of advanced schistosomiasis were first investigated in 2013 and further followed in 2014. Information on clinical history, physical examination, and abdominal ultrasonography, including the symptom of ascites was repeatedly collected. Result showed 44 patients having ascites. Most of the patients' ascites were confined in the kidney area with median area of $20mm^2$. The level of plasma D-dimer and pertinent liver function indicators were measured at the initial investigation in 2013. Compared with those without ascites, cases with ascites had significantly higher levels of D-dimer ($0.71{\pm}2.44{\mu}g/L$ vs $0.48{\pm}2.12{\mu}g/L$, P=0.005), as well ALB (44.5 vs 46.2, g/L) and Type IV collagen (50.04 vs $44.50{\mu}g/L$). Receiver operating characteristic curve analyses indicated a moderate predictive value of D-dimer by its own area under curve (AUC) of 0.64 (95% CI: 0.54-0.73) and the cutoff value as $0.81{\mu}g/L$. Dichotomized by the cutoff level, D-dimer along with other categorical variables generated a prediction model with AUC of 0.76 (95% CI: 0.68-0.89). Risks of patients with specific characteristics in the prediction model were summarized. Our study suggests that the plasma D-dimer level is a reliable predictor for incident ascites in advanced schistosomiasis japonica patients.

Purpose: Total or proximal gastrectomy of the upper-third early gastric cancer (u-EGC) often causes severe post-gastrectomy syndrome, suggesting that these procedures are extremely invasive for patients without pathologically positive lymph node (LN) metastasis. This study aimed to evaluate the clinical applicability of a stomach function-preserving surgery, local resection (LR), with prophylactic left gastric artery (LGA)-basin dissection (LGA-BD). Materials and Methods: The data of patients with u-EGC (pathologically diagnosed as T1) were retrospectively analyzed. Total gastrectomy was performed in 30 patients, proximal gastrectomy in 45, and subtotal gastrectomy in 6; the LN status was evaluated assuming that the patients had already underwent LR + LGA-BD. This procedure was considered feasible in patients without LN metastases or in patients with cancer in the LGA basin. The reproducibility of the results was also evaluated using an external validation dataset. Results: Of the 82 eligible patients, 79 (96.3%) were cured after undergoing LR + LGA-BD, 74 (90.2%) were pathologically negative for LN metastases, and 5 (6.1%) had LN metastases, but these findings were only observed in the LGA basin. Similarly, of the 406 eligible tumors in the validation dataset, 396 (97.5%) were potentially curative. Tumors in the lesser curvature, post-endoscopic resection status, and small tumors (<20 mm) were considered to be stronger indicators of LR + LGA-BD as all subpopulation cases met our feasibility criteria. Conclusions: More than 95% of the patients with u-EGC might be eligible for LR + LGA-BD. This function-preserving procedure may contribute to the development of u-EGC without pathological LN metastases, especially for tumors located at the lesser curvature.

Background: The most frequent fracture seen at the emergency department (ED) in the elderly is a femur fracture whereas they do not know the degree of osteoporosis. We analyzed the degree of osteoporosis in patients with femur fractures and compared patients with only femur fractures (FX) to patients with femur and vertebral fractures (VX) by examining the clinical features, the bone mineral density (BMD), and biochemical markers. Methods: From January 2004 to December 2004, we enrolled prospectively 30 femur fracture patients who visited the ED. The bone mineral densities of the lumbar spine and the femur were examined. Total calcium, phosphate, alkaline phosphatase, osteocalcin, and serum C-terminal telopeptide (s-CTx) were measured. The patients with femur fractures were divided into two subgroups according to the presence of vertebral fracture. Results: All BMDs of the FX group showed osteoporosis. The s-CTx levels were higher than normal. The patients in the FX with VX were older than those in the FX only group, and had lower BMDs. There were no significant differences in markers between the subgroups, but the incidence of trochanteric fractures was higher in FX with VX group than in the FX only group. Conclusion: Femur fractures in the elderly were associated with osteoporosis. In our study, despite a considerable difference in BMD between patients with femur fractures and those with femur fractures combined with vertebral fractures, there was no difference in biochemical markers on bone formation nor in the those of bone resorption. We will further investigate the biochemical markers and BMD in the population of osteoporotic fractures. So those indicators should be helpful for planning treatment and for prevention of FX in the elderly.
