Stevens-Johnson syndrome (SJS) and acute generalized exanthematous pustulosis (AGEP) are 2 distinct entities that can overlap within the spectrum of severe cutaneous adverse reaction (SCAR). AGEP is a self-limiting and drug-induced eruption characterized by sudden onset of sterile pustules, erythema, and sometimes fever. SJS, in contrast, is a severe form of SCAR that causes blistering and necrosis of the skin and mucosal membranes, often leading to significant morbidity and mortality. However, there are cases where patients may present with symptoms that overlap between AGEP and SJS, making it challenging to differentiate the 2 conditions. This report describes a 70-year-old male with nontuberculous mycobacterium tenosynovitis in the left hand, coinfected with methicillin-resistant coagulase-negative Staphylococcus and Klebsiella oxytoca. After administration of additional antibiotics, the patient developed fever and erythematous macules with purpuric centers on the trunk and the extremities. Further examination revealed marked leukocytosis and elevated C-reactive protein levels. Skin biopsy histopathology showed subcorneal intraepidermal pustule formation with neutrophil infiltration. The patient’s clinical course improved after cessation of the culprit drugs and treatment with a high-dose systemic steroid. This case highlights the rare occurrence of SJS/AGEP overlap and underscores the importance of prompt diagnosis and appropriate management of these SCAR.

Background: It is well known that a large number of patients with diabetes also have dyslipidemia, which significantly increases the risk of cardiovascular disease (CVD). This study aimed to evaluate the efficacy and safety of combination drugs consisting of metformin and atorvastatin, widely used as therapeutic agents for diabetes and dyslipidemia. Methods: This randomized, double-blind, placebo-controlled, parallel-group and phase III multicenter study included adults with glycosylated hemoglobin (HbA1c) levels >7.0% and <10.0%, low-density lipoprotein cholesterol (LDL-C) >100 and <250 mg/dL. One hundred eighty-five eligible subjects were randomized to the combination group (metformin+atorvastatin), metformin group (metformin+atorvastatin placebo), and atorvastatin group (atorvastatin+metformin placebo). The primary efficacy endpoints were the percent changes in HbA1c and LDL-C levels from baseline at the end of the treatment. Results: After 16 weeks of treatment compared to baseline, HbA1c showed a significant difference of 0.94% compared to the atorvastatin group in the combination group (0.35% vs. −0.58%, respectively; P<0.0001), whereas the proportion of patients with increased HbA1c was also 62% and 15%, respectively, showing a significant difference (P<0.001). The combination group also showed a significant decrease in LDL-C levels compared to the metformin group (−55.20% vs. −7.69%, P<0.001) without previously unknown adverse drug events. Conclusion The addition of atorvastatin to metformin improved HbA1c and LDL-C levels to a significant extent compared to metformin or atorvastatin alone in diabetes and dyslipidemia patients. This study also suggested metformin’s preventive effect on the glucose-elevating potential of atorvastatin in patients with type 2 diabetes mellitus and dyslipidemia, insufficiently controlled with exercise and diet. Metformin and atorvastatin combination might be an effective treatment in reducing the CVD risk in patients with both diabetes and dyslipidemia because of its lowering effect on LDL-C and glucose.

Angiolipoma is a benign fatty neoplasm that has components of proliferating blood vessels. These types of lesions commonly occur in the subcutaneous tissue of the limbs and trunk. Angiolipoma in the gastrointestinal tract is extremely rare, and the final diagnosis generally depends on histological examination of the excised biopsy. In most previously reported cases, the lesions were diagnosed and treated with surgical management. In this study, we report a case of gastric angiolipoma of approximately 4 cm in size that was diagnosed and treated with endoscopic submucosal dissection.

Background and Objectives: Autophagy is known to be associated with pathogen infection. However, the expression of autophagy-related proteins has not been studied in chronic otitis media without cholesteatoma (COM) or with cholesteatoma (CholeOM). This study aimed to determine whether there is a difference between COM and CholeOM in autophagy-related gene mRNA expression. Subjects and Methods: For 47 patients with chronic otitis media, the inflammatory tissues were classified into granulation tissue (COM) or cholesteatoma (CholeOM) according to biopsy results. Results: PI3K mRNA expression (COM vs. CholeOM, mean±SD, 0.009±0.010 vs. 0.003±0.004; p=0.004) was lower, whereas Beclin-1 mRNA expression (0.089±0.107 vs. 0.176±0.163; p=0.034) was higher in the CholeOM group. Expression of PI3K mRNA in the CholeOM group was lower than that in the COM subgroups with presence of bacteria (0.022±0.019 vs. 0.001±0.001; p=0.001), otorrhea (0.049±0.068 vs. 0.003±0.004; p=0.004), and hearing loss over 40 dB (0.083±0.130 vs. 0.003±0.004; p=0.005). Conclusions The data suggested that different autophagy proteins play important roles in chronic otitis media according to the presence or absence of cholesteatoma.

Purpose: In colorectal cancer surgery, it is important to have accurate resection margins. However, it is challenging to localize lesions during laparoscopy. Therefore, to reduce surgical errors, many preoperative localizing methods have been introduced. In this study, we aimed to assess the preoperative feasibility and safety of autologous blood tattooing. Methods: A total of 11 patients underwent preoperative colonoscopic autologous blood tattooing from August 2017 to February 2020. At the start of the surgery, the surgeon assessed the patients for the precision of visibility and other complications such as abscess or spillage. The patients’ characteristics, outcomes, and complications were collected retrospectively. Results: The study comprised 8 men and 3 women, with an average age of 63 years. Ten patients showed precise visibility, and no localization errors were observed during surgery. No complication was observed in all patients. Conclusion Preoperative autologous blood tattooing is a very useful and safe technique because it has high visibility with no complications. This method does not require additional agents or facilities. A large-scale study will be required to develop standard guidelines.
