Nail growth disturbance commonly takes place after trauma or relevant diseases, such as infections and tumors. However, abnormal growth of the nail plate sometimes occurs without an obvious causative factor. This report presents the case of a patient who underwent male genital reconstruction with a radial forearm free flap for gender affirmation. Although the entire process was smooth, with no accidental events, the second, third, and fourth phalangeal nail plates of the hand from which the flap was harvested showed no evident growth of the fingernail 2 months postoperatively. Nail production was preserved in the remaining fingernails. Typical symptoms, such as redness, swelling, and tenderness, were noted upon clinical observation. Eventually, nail production restarted 5 months after surgery. Steroid and antibiotic treatment was attempted to reduce periungual inflammation. Additionally, close observation with psychological support was conducted.

The majority of South Korean females use sanitary pads, which contain various organic solvents which could be excreted before and during their menstruation. However, they are not provided with findings from studies about the health effects of sanitary pads. Therefore, this study aims to establish a list of potential health hazards of sanitary pads and address the need for further extensive research by pointing out the limitations of the previous literature. A systematic review was adopted to conduct quantitative and qualitative reviews based on the PRISMA (preferred reporting items for systematic reviews and meta-analyses). Studies from electronic databases such as PubMed, RISS, and Google Scholar were retrieved for the final analyses. In accordance with our findings, we proposed a set of limitations of the previous studies. A systematic review revealed that there were effects of sanitary pads on vaginal or vulvar skin, endometriosis, and vaginal microflora. The review also revealed that organic solvents, which sanitary pads are composed of, bring potential harmful effects on pregnancy, autoimmune disease, cardiovascular disease, and neurological development. Social environments such as hygiene use or puberty education also turned out to affect female health. It was inferred that a lack of non-occupational and domestic studies reflecting the distinguishing features of sanitary pads with a reliable sample size remains as an important limitation. This study suggests that organic solvents in sanitary pads may increase some health risks bringing reproductive, autoimmune, cardiovascular, and neurological effects. Due to a lack of studies, a more extensive study can contribute to the public health of South Korean females.

Background: Most studies of systematic drug repositioning have used drug-oriented data such as chemical structures, gene expression patterns, and adverse effect profiles. As it is often difficult to prove repositioning candidates’ effectiveness in real-world clinical settings, we used patient-centered real-world data for screening repositioning candidate drugs for multiple diseases simultaneously, especially for diabetic complications. Methods: Using the National Health Insurance Service-National Sample Cohort (2002 to 2013), we analyzed claims data of 43,048 patients with type 2 diabetes mellitus (age ≥40 years). To find repositioning candidate disease-drug pairs, a nested case-control study was used for 29 pairs of diabetic complications and the drugs that met our criteria. To validate this study design, we conducted an external validation for a selected candidate pair using electronic health records. Results: We found 24 repositioning candidate disease-drug pairs. In the external validation study for the candidate pair cerebral infarction and glycopyrrolate, we found that glycopyrrolate was associated with decreased risk of cerebral infarction (hazard ratio, 0.10; 95% confidence interval, 0.02 to 0.44). Conclusion To reduce risks of diabetic complications, it would be possible to consider these candidate drugs instead of other drugs, given the same indications. Moreover, this methodology could be applied to diseases other than diabetes to discover their repositioning candidates, thereby offering a new approach to drug repositioning.

Beef allergies are relatively rare, especially in adults. However, clinical manifestations can vary from urticaria, angioedema, anaphylaxis to gastrointestinal symptoms. Currently available tests, such as skin testing or in vitro determination of beef-specific immunoglobulin E (IgE), do not provide an accurate diagnosis of beef allergy. The recent development of the basophil activation test (BAT) presents a new opportunity for the diagnosis of food allergies. Here, we report a 37-year-old woman with a history of recurrent generalised urticaria, nausea, vomiting and hypotension after ingestion of beef, suggesting a beef allergy. Although the skin prick test and serum specific IgE to beef, pork and milk allergens showed negative results using commercial kits, the BAT showed significant upregulation of CD203c in a dose-dependent manner compared to both non-atopic and atopic controls. To our knowledge, this is the first case study of beef allergy consisting of a non-IgE-mediated reaction. The detection of food allergies using direct basophil activation is suggested to complement conventional diagnostic tests.

Objective: Menopause symptoms can vary in type, duration, and severity. The purpose of this study was to investigate the key factors predicting severe symptoms among Korean perimenopausal women with various demographic data, obstetric and psychiatric histories, and menopausal symptoms screening scale scores. Methods: Data were collected from 1,060 women, and 4 latent classes were identified using latent profile analysis, with 6 major categories of menopausal complaints. Among the 4 classes, we selectively used data from the “all unimpaired” and “all impaired” groups. Menopause rating scale (MRS), sociodemographic, obstetric, and psychiatric factors were assessed, and hierarchical logistic regression analyses were conducted with the “all impaired” group as a dependent variable. Results: Marital status and scores on the psychological and somatic subscales of the MRS were statistically related to being in the “all impaired” group. Otherwise, family history of menopausal symptoms, menarche age, and history of other psychiatric disorders were not statistically significant predictors of being in the “all impaired” group. Conclusion The psychological and somatic subscales of the MRS predict the severity of perimenopausal syndrome better than obstetric and psychiatric history do among Korean perimenopausal women. Psychological and somatic symptoms as well as genitourinary symptoms in menopausal patients should be closely evaluated.

The incidence of high-pressure injection injuries is increasing with the development of industry and use of injectors. Although high-pressure injection injuries are relatively rare, they commonly lead to complications such as skin necrosis, infection, and amputation. Moreover, the initial presentation is prone to be underestimated because of the small entry point at the patient’s first encounter in emergency care. A prompt surgical intervention is required, with appropriate and rapid initial treatments, including broad-spectrum antibiotics and tetanus toxoid. The surgical treatment involves wide debridement for foreign material removal and subsequent reconstruction. In this case report, we present three cases we encountered and the ensuing complications. All three patients who received the same treatments are discussed in detail.

BACKGROUND: Skeletal muscles play many important roles in the human body and any malfunction or disorder of the skeletal muscles can lead to a reduced quality of life. Some skeletal dysfunctions are acquired, such as sarcopenia but others are congenital. Duchenne muscular dystrophy (DMD) is one of the most common forms of hereditary muscular dystrophy and is caused by a deficiency of the protein, Dystrophin. Currently, there is no clear treatment for DMD, there are only methods that can alleviate the symptoms of the disease. Mesenchymal stem cells, including tonsil-derived mesenchymal stem cells (TMSCs) have been shown to differentiate into skeletal muscle cells (TMSC-myocyte) and can be one of the resources for the treatment of DMD. Skeletal muscle cell characteristics of TMSC-myocytes have been confirmed through changes in morphology and expression of skeletal muscle markers such as Myogenin, Myf6, and MYH families after differentiation.MEOTHDS: Based on these characteristics, TMSC-myocytes have been transplanted into mdx mice, a mouse model of DMD, to investigate whether they can help improve the symptoms of DMD. The red fluorescent protein gene was transduced into TMSC (TMSC-R) for tracking transplanted cells. RESULTS: Prior to transplantation (TP), it was confirmed whether TMSC-R-myocytes had the same differentiation potential as TMSC-myocytes. Increased expression of dystrophin and autophagy markers in the TP group compared with the sham group was confirmed in the gastrocnemius muscle 12 weeks after TP. CONCLUSION These results demonstrate muscle regeneration and functional recovery of mdx via autophagy activation following TMSC-myocyte TP.
