Background/Aims: This study aimed to investigate co-occurrence and clinical characteristics of sexually transmitted infections (STIs) and pelvic inflammatory disease (PID) in women hospitalized for acute pyelonephritis (APN). Methods: This single-center retrospective study reviewed medical records of inpatients with APN from January 2019 to February 2023 and identified records of 142 patients who were referred to a gynecologist to evaluate gynecological diseases including STIs. Results: Of the 142 patients, 47 were tested positive for sexually transmitted pathogens in nucleic acid amplification testing, confirming the presence of STIs. In patients with APN, those with STIs were more likely to have lower abdominal pain or cervical motion tenderness (CMT) on pelvic examination and leukocytosis (> 14.5 × 109/L) than those without STIs. Of the 93 patients who underwent pelvic examination, 34 had CMT with one or more of additional criteria for the clinical diagnosis of PID, such as abnormal vaginal discharge and leukorrhea confirmed by microscopic examination, which could be clinically diagnosed as PID. Conclusions In sexually active women with APN, it is important to evaluate the possibility of STIs and PID, considering several risk factors such as lower abdominal pain, abnormal vaginal discharge, CMT, and leukocytosis.

Background: As the coronavirus disease (COVID-19) pandemic continues, wearing masks has become a daily routine. As the mask-wearing time increased, the mask-covered skin was more likely to be influenced. Objective: This study aimed to identify face mask-wearing behaviors and their effects on patients with facial skin diseases. Methods: Patients with facial skin disease were surveyed at two institutions. The patterns of mask use, mask-associated skin problems, and the Dermatology Life Quality Index (DLQI) were investigated. Results: A total of 174 participants were enrolled and the mean age was 42.2 years. Rosacea (35.6%) was the most common condition, followed by acne (25.3%) and contact dermatitis (17.2%). Ninety-four subjects (54.0%) reported that they wore masks for less than 6 hours a day, and 96 subjects (55.2%) wore masks to fit tightly against the face. Regarding the mask type, KF-99, 94, and 80 (62.6%) were the most common. Nearly three-quarters (n=128, 73.6%) of patients complained of mask-associated skin problems. Pimples were the most common symptom (59.4%), and the cheek was the most commonly affected area (67.2%). The mean DLQI score was 9.90. Conclusion We investigated the current patterns of mask use in patients with facial skin diseases. Moreover, it is necessary to recognize newly encountered relationships and seek strategies for relevant patients.

Background: Analysis of hair microscopic morphology is a simple and less invasive method to differentiate alopecia areata (AA) from other alopecic diseases. However, there is limited information on the distribution of the microscopic characteristics. Objective: This study evaluated the microscopic morphological characteristics of pulled-out hair and their correlation with disease course in AA. Methods: Morphological characteristics of pulled-out hair were classified into 5 categories:the presence of typical clubbing, surface undulation, tapering, breakage, and depigmentation in proximal hair shaft. Clinical course of AA was investigated through assessment of Severity of Alopecia Tool (SALT) score (initial score, maximal score and difference of them [ΔSALT]). Results: Among 1,272 pulled-out hairs (n=179) obtained at initial visit, depigmentation (59.5%) was the most common, followed by loss of typical clubbing (57.2%) and surface undulation (55.2%). The percentage of loss of typical clubbing and proximal tapering was significantly higher in severe type of AA, younger age of onset and shorter disease duration. The ratio of typical clubbing (<50% vs. ≥50%) was associated with difference in maximal score and ΔSALT (p<0.05). Strong activity group (pulled-out hair ≥10, n=33) showed difference in clinical course (maximal score, ΔSALT) as well as distribution of microscopic features (loss of typical clubbing) compared with those in non-strong activity group. The ratio of typical clubbing significantly increased at follow-up than initially in strong activity group (p<0.05). Conclusion Microscopic hair morphology, especially loss of typical clubbing and proximal tapering, could be useful tool to predict the course of AA.

Background: It is well known that adequate water intake and moisturizer application improves skin barrier function. Objective: This study was conducted to analyze the effects of daily water intake and moisturizer application on skin barrier function and the degree of response to barrier recovery. Methods: Participants with daily water intake more than 1 L were classified as high daily water intake group (H) and those with less than 1 L as low daily water intake group (L). Each group was subcategorized into four groups according to intervention method: additional water intake (H1, L1), moisturizer (H2, L2), both (H3, L3), and control (H4, L4). Transepidermal water loss (TEWL) and stratum corneum hydration (SCH) were measured at baseline during the 2nd and 4th week. Results: A total of 43 participants completed the study (H: 22, L: 21). At baseline, there was no significant difference in SCH and TEWL in any on the anatomical sites between the high daily water intake and low daily water intake groups. However, SCHs of left forearm (group H2, p=0.004; group H3, p=0.004), left hand dorsum (group H2, p=0.010; group H3, p=0.026), and left shin (group H2, p=0.016; group H3, p=0.001) in group H2 and H3 were significantly increased in the 4th week as compared to the baseline values. Conclusion The results suggest that the degree of water intake may be related to improved skin barrier function. However, application of additional moisturizers had more favorable impact on skin hydration as compared to additional water intake.
