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><B>Abstract</B></P> <P>Au nanoparticles (NPs) were incorporated into the channels of freestanding TiO<SUB>2</SUB> nanotube arrays (TNTAs) by an electrodeposition method and then applied to dye-sensitized solar cells (DSSCs) for light harvesting to improve the power conversion efficiency (PCE). The average size of Au NPs incorporated into TNTA channels was approximately 70nm, and the extinction of the Au NPs by UV–vis spectra was approximately 530nm, which is similar to the absorbance of the ruthenium dye (N719) used in DSSCs. The PCE of DSSCs based on TNTAs containing Au NPs increased to 6.80% from a PCE of 5.66% without Au NPs, an enhancement of 20.14% owing to light harvesting from the NP plasmonic and charging effects. However, the PCE of DSSCs based on TNTAs with excess Au NPs decreased from 6.80% to 5.49% due to aggregation of the Au NPs, which led to a decreased open-circuit voltage and fill factor.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Incorporation of Au nanoparticles in the channel of TiO<SUB>2</SUB> nanotube arrays. </LI> <LI> Application of incorporation of Au nanoparticles in DSSCs. </LI> <LI> The plasmonic and charging effects of DSSCs by Au nanoparticles. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

The purpose of this study was to analyze the effects of aerobic exercise and resistance exercise on body composition, complete blood count (CBC) and metabolic syndrome factors in postmenopausal women. Twenty healthy postmenopausal women composed of the step box exercise and resistance exercise group (n=10) or to a “no exercise” control group (n=10). The variables of body composition, CBC, and metabolic syndrome factors were measured in all the subjects before and after the 12-week study. Waist circumference, lean body mass and % body fat had significantly decreased, but no significantly differences in blood pressure, total cholesterol, triglyceride, high-density lipoprotein cholesterol, and CBC in the post combined exercise group. However, individual metabolic syndrome factors were decreased compared to before combined exercise training and after combined exercise training. Our findings indicate that regular and continuous aerobic exercise and resistance exercise improves body composition, visceral fat and CBC factors. Consequently, exercise intensity and duration will be effective for preventing the immune system caused by metabolic syndrome patients in postmenopausal women.

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.
