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.

<P>Background. Clinical application of encapsulated islet transplantation is hindered by low biocompatibility of capsules leading to pericapsular fibrosis and decreased islet viability. To improve biocompatibility, we designed a novel chitosan-coated alginate capsules and compared them to uncoated alginate capsules. Methods. Alginate capsules were formed by crosslinking with BaCl2, then they were suspended in chitosan solution for 10 minutes at pH 4.5. Xenogeneic islet transplantation, using encapsulated porcine islets in 1,3-galactosyltransferase knockout mice, and allogeneic islet transplantation, using encapsulated canine islets in beagles, were performed without immunosuppressants. Results. The chitosan-alginate capsules showed similar pore size, islet viability, and insulin secretory function compared to alginate capsules, in vitro. Xenogeneic transplantation of chitosan-alginate capsules demonstrated a trend toward superior graft survival (P = 0.07) with significantly less pericapsular fibrosis (cell adhesion score: 3.77 +/- 0.41 vs 8.08 +/- 0.05; P < 0.001) compared to that of alginate capsules up to 1 year after transplantation. Allogeneic transplantation of chitosan-alginate capsules normalized the blood glucose level up to 1 year with little evidence of pericapsular fibrotic overgrowth on graft explantation. Conclusions. The efficacy and biocompatibility of chitosan-alginate capsules were demonstrated in xenogeneic and allogeneic islet transplantations using small and large animal models of diabetes. This capsule might be a potential candidate applicable in the treatment of type 1 diabetes mellitus patients, and further studies in nonhuman primates are required.</P>

Cryptogenic organizing pneumonia (COP) is an idiopathic interstitial pneumonia characterized by a subacute course and favorable prognosis with corticosteroids. However, some patients show resistance to steroids. Macrolides have been used with success in those patients showing resistance to steroids. A few reports showed treatment failure with macrolides in patients with COP who were resistant to steroids. In this report, we described two cases of COP who showed different responses to clarithromycin. One recovered completely, but the other gradually showed lung fibrosis with clarithromycin.

Identifying the extracellular metabolites of microorganisms in fresh vegetables is industrially useful for assessing the quality of processed foods. Pectobacterium carotovorum subsp. carotovorum (PCC) is a plant pathogenic bacterium that causes soft rot disease in cabbages. This microbial species in plant tissues can emit specific volatile molecules with odors that are characteristic of the host cell tissues and PCC species. In this study, we used headspace solid-phase microextraction followed by gas chromatography coupled with mass spectrometry (HS-SPME-GC-MS) to identify volatile compounds (VCs) in PCC-inoculated cabbage at different storage temperatures. HS-SPME-GC-MS allowed for recognition of extracellular metabolites in PCC-infected cabbages by identifying specific volatile metabolic markers. We identified 4-ethyl-5-methylthiazole and 3-butenyl isothiocyanate as markers of fresh cabbages, whereas 2,3-butanediol and ethyl acetate were identified as markers of soft rot in PCC-infected cabbages. These analytical results demonstrate a suitable approach for establishing non-destructive plant pathogen-diagnosis techniques as alternatives to standard methods, within the framework of developing rapid and efficient analytical techniques for monitoring plant-borne bacterial pathogens. Moreover, our techniques could have promising applications in managing the freshness and quality control of cabbages.

휴폐광산 인근 주민에 대한 위해영향을 평가하는데 있어서 벼 품종에 따른 변이를 파악하기 위하여 농경지 토양 및 쌀의 비소, 카드뮴, 구리 및 납의 함량을 분석하였다. 중금속 오염농경지에서 조사된 잠재적인 인체노출경로로서 오염된 농경지 및 쌀을 통한 경구섭취 및 피부접촉을 통한 품종간 일일평균 인체노출량(ADD)을 산정하였다. 비발암성 위해도 평가로 노출경로별 중금속의 위험비율인 HQ 지수와 모든 노출경로를 총합한 중금속의 위험지수인 HI 값을 US-EPA D/B를 활용하였다. 벼 품종간 HI 지수는 23.6∼34.3으로 전품종에서 높은 잠재적 위해성으로 평가되었는데 DA 품종이 가장 낮은 반면 TB 품종이 가장 높은 HI 값을 보였다. 쌀 소비에따른 비소의 발암성 위해도 평가는 품종간 2.0E-03∼3.5E-03을 보여 미국 EPA에서 정한 위해성 기준인 만명중 한명 이상으로 높게 나타났다. 발암성 위해도에 대한 품종간 비교에서 DA 품종이 가장 낮은 반면 TB 품종이 가장 높은 HI 값을 보였다. 이러한 결과는 위해성 평가가 중금속 오염에 안전한 품종을 선발하는데 유용한 도구로서 활용할 수 있음을 보여준다. Heavy metal pollution may be one of the most serious challenges confront crop production and human health. Therefore, the selection of heavy metal tolerance cultivars which adapted to the contaminated fields will introduced a suitable solution for management this critical environmental risk. The objectives of this research is to assess human health risk using geochemical analyses and exposure assessment of heavy metals in rice cultivars. Risk for inhabitants in the closed mine area was comparatively assessed for As, Cd, Cu and Pb in 10 rice varieties as a major exposure pathway. The average daily dose (ADD) of each heavy metal was estimated by analyzing the exposure pathways to rice and soil. For the non-carcinogenic risk characterization, Hazard Quotient (HQ) and Hazard Index (HI) were calculated using toxicity indices provided by US-EPA IRIS. The different rice varieties revealed a wide range of HI values from 23.6 to 34.3, indicating that all rice varieties have a high potential toxic risk. The DA rice variety showed the lowest HI value while the TB rice variety the highest. The probabilities of cancer risk for As via rice consumption were varied with rice varieties ranging from 2.0E-03 to 3.5E-03 which exceeded the regulatory acceptable risk of 1 in 10,000 set by US-EPA. The DA rice variety also showed the lowest value while the TB rice variety gave the highest value. Our results indicate that risk assessment can be contribute to screen the pollution safe rice cultivars in paddy fields affected by the mining activity.
