In this study, the evidence of thread embedding acupuncture (TEA) in treating cervical radiculopathy in randomized controlled trials was investigated. We searched 16 databases up to August 22, 2022. Of the 2,644 studies retrieved, 22 randomized controlled trials (2,483 participants) were selected. Quality assessments were performed using Cochrane's risk-of-bias tool and RevMan 5.4 software. Outcome measures in the included studies typically showed TEA had a significant therapeutic effect compared with simple acupuncture and other remedies, and TEA was better than sham TEA. Catgut and polydioxanone had no difference in effectiveness, however, catgut was considered to be less safe. TEA was shown to be more therapeutic when inserted deeper into the skin. Ultrasound guided TEA was more effective and safer than conventional TEA, and using a flat blade needle was better than conventional needles for TEA. No serious adverse events were reported from using TEA, and only a few mild side effects were observed. However, the limited number and heterogeneity of the included studies, together with the unclear methodological quality, indicate that higher-quality studies need to be conducted to determine the effectiveness and safety of TEA for cervical radiculopathy.

Purpose: The purpose of this study was to assess the frequency and characteristics of occupational blood and body fluid exposure for operating room personnel during surgical procedures and identify risk factors. Methods: A self-report questionnaire was used to survey 519 operating room personnel who participated in 132 surgeries in an acute care hospital in Seoul between April 12 and 20, 2006. Results: The response rate was 82% (530/646) and analyzed total 519 except for improper 11 questionnaires. Exposure rate was 45.5% (60/132) during operations and 20.4% (106/519) for operating room personnel. By job categories, the exposure rate was as follows; anesthesiologists and nurses 31.2% (44/141), operators and assistants 22.1% (32/145), circulating nurses 12.0% (11/92), scrub nurses 11.4% (14/123). The mucous membrane-eye exposure with a high risk of transmitting infection was 6.6% (7/106) and the most frequent route of exposure was blood and body fluid touching unprotected skin. In multivariate analysis, the risk factors of exposure were services, duration of operation, a patient who had a peripheral arterial catheter line, and job category. Conclusion: Educational programs and appropriate use of personal protective equipment are necessary to prevent operating room personnel from being exposed to blood and body fluid.

In this study, partition coefficients(Kw) of phenoxyethanol in oil-water phase according to type of oils was investigated. Partition coefficients(Kw) were experimented by classified oils that hydrocarbones, fatty alcohols, fatty acids, esters, triglycerides and silicones. It was found that partition coefficients(Kw) of hydrocarbons and silicones were low, but partition coefficients(Kw) of fatty acids, fatty alcohols, esters and triglycerides were high. It was known that the emulsions which were made of oils having low partition coefficients value had a good antimicrobial effects. Thus, the cosmetics stability of microorganisms and skin safety of phenoxyethanol could be improved by using the oils which have low partition coefficients value.

An analysis of biosignal and performance data collected during driving has increasingly employed in research to explore a human-vehicle interface design for better safety and comfort. The present study developed a protocol and a system to effectively analyze biosignal and driving performance measurements in various driving conditions. Electrocardiogram (ECG), respiration rate (RR), and skin conductance level (SCL) were selected for biosignal analysis in the study. A data processing and analysis protocol was established based on a comprehensive review of related literature. Then, the established analysis protocol was implemented to a computerized system so that immense data of biosignal and driving performance can be analyzed with ease, efficiency, and effectiveness for an individual and/or a group of individuals of interest. The developed analysis system would be of use to examine the effects of driving conditions to cognitive workload and driving performance.

Aim of the study: The objective of this systematic review is to critically evaluate the evidence of the effectiveness and safety of external application of herbal medicines (EAHM) for acne vurgalis (AV). Methods: English, Chinese and Korean language databases were searched up to May 2018. Randomized clinical trials (RCTs) that reported the effects of EAHM for AV were included and analysed. Results: A total of 10 randomized trials with 656 AV patients were identified. A meta-analysis of two RCTs indicated that EAHM had a significant effect on improving primary outcome 'global assessment' compared with placebo (mean difference (MD) = -2.62, confidence interval (CI) = -4.84 to -0.40, p = 0.02). Furthermore, data extracted from two RCTs showed that EAHM significantly reduce primary outcome 'inflammatory lesion count of acne' (MD = -1.25, CI = -1.68 to -0.83, p < 0.00001) and 'non-inflammatory lesion count of acne' (MD = -1.32, CI = -1.75 to -0.90, p < 0.00001). No significant difference was observed between groups in secondary outcome 'sebum of skin' (MD = -0.21, CI = -0.53 to 0.11, p = 0.20) and 'patient-reported changes in symptom' (relative risk (RR) = 2.56, CI = 0.43 to 15.22, p = 0.30). No severe adverse events (AEs) were found and no treatment was stopped due to AEs of EAHM. Conclusions: EAHM seems to have affirmative effects, but quality of evidence, and non-standardized use of EAHM make our conclusion weak. Our suggestion is rigorously designed RCTs and standardization of EAHM are required in the future.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.

Purpose: Sacral dimples are a common cutaneous anomaly in infants. Spine ultrasonography (USG) is an effective and safe screening tool for patients with a sacral dimple. The aim of this study was to determine the clinical manifestations in patients with an isolated sacral dimple and to review the management of spinal cord abnormalities identified with USG. Methods: We reviewed clinical records and collected data on admissions for a sacral dimple from March 2014 through February 2017 that were evaluated with spine USG by a pediatric radiologist. During the same period, patients who were admitted for other complaints, but were found to have a sacral dimple were also included. Results: This study included 230 infants under 6-months-old (130 males and 100 females; mean age $52.8{\pm}42.6days$). Thirty-one infants with a sacral dimple had an echogenic filum terminale, and 57 children had a filar cyst. Twenty-seven patients had a low-lying spinal cord, and only one patient was suspected of having a tethered cord. Follow-up spine USG was performed in 28 patients, which showed normalization or insignificant change. Conclusion: In this study, all but one infant with a sacral dimple had benign imaging findings. USG can be recommended in infants with a sacral dimple for its convenience and safety.

SKI 2053R and SKI 2053R-human serum albumin(HSA) mixture were examined for their antigenicity in Hartley guinea pigs as well as C57BL/6 mice in comparison with distilled water (DW), HSA and DW-HSA conjugate. Several antigenicity tests, including acitive systemic anaphylaxis(ASA), passive systemic anaphylaxis (PSA), passive cutaneous anaphylaxis (PCA) and indirect hamagglutination test (IHA), were performed according to the Established Regulations of National Institute of Safety Research. The results were as follows: 1. When guinea pigs were sensitized with SKI2053R or SKI2053R-HSA emulsified with complete Freund's adjuvant(CFA), these animals showed negative reactions in ASA and PSA. 2.No blue spot was observed on the back skin of guinea pigs in the PCA test. 3. Sera from guinea pigs revealed a negative reaction in IHA. 4.Guinea pigs were sensitized by HSA emulsified with CFA as a positive control, and these animals showed positive reactions in ASA, PSA, PCA, and IHA. As shown above, SKI2053R was considered to possess neither antigenic, nor haptenic properties, and confirmed not to have the haemagglutinating activity.

Even though maxillary cancer is usually discovered in advanced stage, its regional lymph node or distant metastases are not common comparing to other head and neck cancer. So the result of treatment depends upon local control of the tumor. Because maxillary sinus is anatomically located adjacent to orbit and skull base, it is difficult to remove the tumor completely with sufficient safety margin like in other malignant tumor. Traditionally, surgery including aggressive resection, radiotherapy or both combined therapy have been widely accepted in many institutes, but their results are not still satisfactory. Sixteen cases of maxillary cancer( all squamous cancer, T2 1 case, T3 6 cases, T4 9 cases, mean age 57.2 years) were treated by intraarterial chemotherapy, raditherapy and surgery and followed up retrospectively. 5 year survival rate by Kaplan-Meier method was 51.95%, and orbit, palate or cheek skin could be preserved in many cases and their functional result was good.
