Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

Background: Solar urticaria (SU) is an uncommon type of photodermatoses characterized by erythematous wheal with pruritus after sunlight exposure, which shows a female predominance. Only a few studies to analyze the clinical features of SU were reported in Asia. Objectives: We aimed to analyze the clinical and photobiological characteristics of SU in Korea. Methods: We retrospectively investigated the medical records of patients with SU who visited the department of dermatology, Konkuk university medical center from January 2005 to January 2020. Results: Of a total of 44 patients, 36 (81.8%) were male and 8 (18.2%) were female. The mean age at onset was 17.6 years (range, 5-47) and the mean threshold time was 19.7 minutes. Among 32 patients who underwent phototesting, the action spectrum most commonly implicated was ultraviolet (UV) A only in 12 (37.5%), and then visible light (415nm) only was responsible for SU in 8 (25.0%). Three patients (9.4%) were induced by both UVA and visible light (415nm). Even 4 patients (12.5%) were triggered by only natural sunlight. Serum immunoglobulin E levels were measured in 33 patients, and 17 (51.5%) showed values higher than normal. The treatment most widely used were oral antihistamine (43.2%), followed by phototherapy (13.6%). Conclusion: SU is a rare photodermatosis in Korea, which shows a male preponderance. In this study, UVA and visible light (415nm) were predominant action spectrum of SU.

( Su Hwan Shin ),( Won Lee ),( So Yoon Kim ),( Gwanghyun Jo ),( Je-ho Mun ),( Soo Ick Cho ) 대한피부과학회 2019 Annals of Dermatology Vol.31 No.3

Background: Both medical disputes and the incidence of skin cancer are increasing in Korea. Objective: The aim of this study was to figure out the medical litigation related to skin cancer and propose a method to prevent the medical disputes. Methods: Skin cancer-related judgments were searched by The Supreme Court of Korea’s Written Judgment Management System based on the keywords for skin cancer. The search system included sentenced cases at the Lower Courts, the Appellate Courts, and the Supreme Court from 1997 to 2017. Results: Seven cases were selected as the litigation cases related to skin cancer. Four cases (57.1%) presented malignant melanoma, while the rest presented squamous cell carcinoma, metastatic skin cancer, and peripheral T cell lymphoma (1 case in each). Four cases resulted in death from cancer metastasis, and 3 cases presented as sequelae. The legal issues related to the medical disputes could be categorized as follows: misdiagnosis, delayed diagnosis, performance error, and lack of informed consent. Delayed diagnosis and lack of informed consent were the most common issues (n=4) in the precedents. Five cases (71.4%) were sentenced the awarded amounts to the plaintiff, including 2 cases of settlement decision. The average awarded amount was 42,553,644±27,567,455 Korean won. Conclusion: Physicians should pay attention to the cases of the skin cancer to prevent medical malpractice and disputes. The practices pertaining to proper diagnosis, treatment plans, and obtaining an informed consent should be followed during the course of treating skin cancer. (Ann Dermatol 31(3) 300∼306, 2019)

Byoung-won Park,Seong Soon Kwon,Min Ho Lee,Do Hoi Kim,Min Su Hyon,Duk Won Bang 순천향대학교 순천향의학연구소 2018 Journal of Soonchunhyang Medical Science Vol.24 No.1

Objective: Contrast-induced nephropathy (CIN) frequently occurs after percutaneous intervention. Objective of this study was to investigate the usefulness of serum cystatin C, neutrophil gelatinase-associated lipocalcin (NGAL), urinary kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18) as early predictors for CIN after percutaneous coronary intervention (PCI). Methods: In 53 patients who underwent PCI were enrolled. Serum creatinine and cystatin C level were measured immediately before, and 24 hours and 48 hours after catheterization. Serum NGAL, urinary KIM-1, and IL-18 were measured immediately before, and 4 hours, 24 hours, and 48 hours after catheterization. CIN was defined as a rise in creatinine 0.5 mg/dL or 25% above baseline. Results: CIN occurred in four patients (7.5%). Serum cystatin C levels were higher at 24 hours and 48 hours in CIN patients than in those without CIN (P<0.05). Serum NGAL levels were higher at 48 hours in CIN patients than in those without CIN. Urinary KIM-1 levels were higher at 48 hours in CIN patients than in those without CIN. There were no significant markers of CIN on multi-variate analysis. Conclusion: In this study, the occurrence of CIN after PCI was 7.5%. Although there were some time-course changes in serum cystatin C and urinary KIM-1 after PCI, there was no significant predictor for CIN after PCI.

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.

( Tae-hee Kim ),( Yesol Kim ),( Do-won Jeong ),( Eun-gyeong Lee ),( Dong-su Jeon ),( Jun-mo Kim3 ) 대한폐경학회 2015 대한폐경학회지 Vol.21 No.2

Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosomeautosome translocation with a literature review. (J Menopausal Med 2015;21:112-114)

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.
