Purpose: The aim of this study is to prepare medical staff in order to prevent medical malpractice litigation through analysis of litigation cases related to the department of surgery in Korea. Methods: A total of 94 litigation cases related to the department of surgery, where a certain amount of payment was ordered to the defendant between 2005 through 2010, were analyzed. We examined time of occurrence, amount claimed and awarded in damages, plaintiff claims, and court opinion. Results: An average of 3.2 years was spent from the date of the incident occurring to the end of the litigation procedures. The average amount awarded in judgments for damages was 59,708,983 ± 67,307,264 (range, 1,700,000–365,201,482) Korean won. Cases were found involving the following opinion of the court: violation of duty of care (49 cases), violation of informed consent (7 cases), violation of duty of care and informed consent (5 cases), and settlement, reconciliation, and others (32 cases). By analyzing defendants’ negligence in court opinions, diagnosis (30.8%) was the most common, followed by post-operation management (27.7%). Conclusion: Physicians have to conduct treatment and surgery based on exact diagnosis and be careful to observe patients’ conditions and symptoms after surgery. It is essential to identify the current status and characteristics of medical litigation for reducing further litigation and improving patient safety. In order to create a safe medical environment, national efforts should be made not only by individuals but also at the national level.

Background: Medicolegal disputes are increasing in practical medicine. Acne is a common problem but is usually related to cosmetic problems such as acne scars. Medications or procedures related to acne could lead to medical malpractice. Objectives: To analyze medical litigation associated with acne or acne scar in South Korea. Methods: Acne-related judgements were searched using the Supreme Court of Korea’s Written Judgment Management System based on the keywords “acne” or “acne scar.” Results: Eleven cases were selected as litigated cases of acne or acne scar. Eight cases (72.7%) were related to acne scar and three (27.3%) were related to acne. Treatment modalities such as peeling (n = 6), laser treatment (n = 3), photodynamic therapy (n = 1), and antibiotic (n = 1) resulted in lawsuit. Claimed sequelae of the treatment were hyperpigmentation (n = 5), scar worsening (n = 5), erythema (n = 3), skin bumps (n = 1), and liver transplant (n = 1). Eight cases (72.7%) were awarded to the plaintiff, and the others were dismissed. The average awarded amount was 16,801,324± 24,452,486 (mean±standard deviation) Korean Won. Conclusion: Various treatments for acne or acne scar can cause medical disputes. Unnecessary litigation could be prevented if simple measures such as history taking, choosing proper procedure, and adequate management after the procedure along with sufficient informed consent were performed.

Background/Aims: Urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) have been recently discovered and validated as sensitive biomarkers that can predict stage 2 or 3 acute kidney injury (AKI) development in high-risk patients. We aimed to assess whether these biomarkers could predict adverse outcomes and renal recovery in established AKI patients. Methods: This was a single-center study prospectively enrolling 124 patients diagnosed with AKI. TIMP-2, IGFBP7, neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule 1 (KIM-1) levels were measured at the time of diagnosis and the predictive performance of short-term outcomes and renal recovery was assessed. Results: Patients were divided into 4 quartiles according to the initial urinary TIMP-2/IGFBP7 levels. Stage 3 AKI (odds ratio [OR], 17.86), classified by the Kidney Disease Improving Global Outcomes (KDIGO), as well as the third and fourth quartiles of TIMP-2/IGFBP7 (OR, 5.75 and 44.98, respectively), were found to be independent predictors of renal replacement therapy at the time of AKI diagnosis. In addition, KDIGO stage 3 AKI (OR, 2.468) or the third of fourth quartiles of urinary TIMP-2/IGFBP7 (OR, 1.896 and 3.622, respectively) were also found to be useful in predicting nonrecovery of renal function. In a separate analysis of patients with renal recovery at discharge, initial urinary TIMP-2/IGFBP7 or urinary IGFBP7 at discharge could also predict new-onset or progressive chronic kidney disease (CKD). Conclusions: In AKI patients, urine TIMP-2/IGFBP7 could serve as a biomarker for predicting adverse outcomes, renal recovery, or the development and progression of CKD.

Background/Aims: Possible fatal complications arising from coronary angiography (CAG), percutaneous coronary intervention (PCI), and coronary artery disease itself, are likely to cause medical disputes. Presenting the current status and reasons for judgments given in lawsuits related to CAG/PCI, this study aimed to identify ways to prevent unnecessary disputes and medical malpractice suits related to CAG/PCI through lawsuit analysis. Methods: A total of 13 cases (20 judgments) found in the Supreme Court of Korea’s Written Judgment Management System from 1998 to 2017 were analyzed. Results: Coronary artery injury was the most common causative complication that led to lawsuits (n = 6, 46%). Six cases (46%) were ruled in favor of the plaintiff for violation of duty of care (n = 4) and duty of explanation (n = 2), respectively. Cases that violated duty of care included two errors in intra-procedure device manipulation, one in pre-procedure diagnosis, and one in management of post-procedure complication. Lack of explanation regarding the risk of complications was pointed out in both cases that violated duty of explanation. The average awarded amount for the damages was 114,436,064 Korean won. Conclusions: Physicians need not fear unfair judgments so long as they follow standard of care because the Court consistently looked at the probability, the foreseeability, and the evidence. Therefore, maintaining standard of care is important. Besides, specific, detailed, and comprehensible explanations, including the risk of complications in addition to the necessity of procedures, are important to ensure the patient clearly understands the possible risk of adverse outcomes.

침샘은 하루 1.5 l의 침을 분비하며, 일반적으로 침샘에서 수분이동은 능동적 염분 이동에 따른 삼투현상에 의해 일어난다. 따라서 침샘에서 높은 수분투과성으로 인해 수분통로 단백인 aquaporin (AQP)들이 풍부하게 존재할 수 있다. 지금까지침샘에 4가지 형태의 AQP이 존재한다고 알려져 있지만 침샘에서 정확한 위치와 수분 이동에 대한 각 AQP들의 역할은 아직 확실치 않다. 본 연구는 300 g 정도의 흰쥐를 pentobarbital sodium (50 mg/kg, IP) 마취하에서 carbarchol (10 μg/kg)을 복강 내 투여한 후 AQP들의 역할과 분포를 면역조직화학방법으로 조사하였다. AQP1은 침샘의 미세혈관의 내피세포와 샘세포와 샘관 주위에 존재하는 근육상피세포에 존재하였다. AQP4는 침샘관의 마지막 부위인 배출관에 존재하였다. AQP5는 주로 장액세포의 바닥가쪽과 세포사이 분비소관을 포함한 세포꼭대기쪽막 에 존재하였으며 콜린성 분비 자극으로 세포꼭대기쪽막으로 이동되어 밀집되었다. AQP5는 모든 침샘의 사이관과 줄무늬 관에도 존재하였으며 점액세포는 약하게 존재하였다. AQP8은 AQP5처럼 장액세포의 바닥쪽막과 세포사이 분비소관을 포함한 세포꼭대기쪽막에 존재하였으며 콜린성 침분비 자극으로 세포꼭대기쪽막쪽으로 이동되어 밀집되었다. 이상의 실험결과는 AQP5와 AQP8이 장액세포에서 일차 침 형성시 일어나는 수분이동의 주된 통로임을 시사하였다. The salivary glands produce 1.5 l of fluid per day. As in other organs, the general paradigm in the salivary glands is that water movement occurs secondary to osmotic driving forces created by active salt transport. Therefore, high water permeability in salivary glands is expected to need a variety of aquaporin (AQP), a water channel. Although four AQPs have been known to reside in salivary glands, the precise location and roles of AQPs have been not well examined. This study is aimed to investigate the distribution of AQPs in 3 major salivary glands and their changes after cholinergic stimulation using immunohistochemical study in Sprague Dawley rats weighing 300 g under pentobarbital sodium anesthesia. AQP1 was localized in the endothelial cells of all salivary capillary vessels and the myoepithelial cells. AQP4 was demonstrated in the epithelium of the excretory ductal cells of all salivary glands. AQP5 and 8 were abundantly present in the basolateral membrane and apical membranes of the serous acini including intercellular secretory canaliculi, whereas AQP5 was weakly present in mucous acini. In addition, AQP5 was found in the epithelium of the intercalated and striated ducts. Upon stimulation of carbachol (10 μg/kg, I.P). AQP5 and 8 tended to translocate from basolateral membrane to the apical membrane, appearing as clusters of dots. These results suggest that AQP5 and 8 are the candidate molecules responsible for the water movement in salivary acinar cells.

Edible insects are considered novel protein sources, and the edible insect breeding industry is growing rapidly. However, fungal pathogens are a major threat to this industry, and appropriate identification of causative agents is important for the development of antifungal agents. In 2019, strains of the fungal pathogen Metarhizium were isolated from infected second and third instar larvae of the economically important edible insect Protaetia brevitarsis, which were collected from separate farms in Gimhae-si, Gyeongsangnam-do, Korea. Based on morphological characteristics and multilocus phylogenetic analysis of the internal transcribed spacer region, and 50-region of gene encoding the 1-α elongation factor, the fungal strains were identified as Metarhizium majus. Here, we report the detailed phylogenetic characteristics and morphological description of this species, which is prevalent in Korea. Identification of the principal disease-causing agent can help develop disease prevention and antifungal strategies for application in edible insect-rearing farms.
