Background: Primary cutaneous CD30+ lymphoproliferative disorders (pcCD30-LPDs) are a diseases with various clinical and prognostic characteristics. Objective: Increasing our knowledge of the clinical characteristics of pcCD30-LPDs and identifying potential prognostic variables in an Asian population. Methods: Clinicopathological features and survival data of pcCD30-LPD cases obtained from 22 hospitals in South Korea were examined. Results: A total of 413 cases of pcCD30-LPDs (lymphomatoid papulosis [LYP], n=237; primary cutaneous anaplastic large cell lymphoma [C-ALCL], n=176) were included. Ninety percent of LYP patients and roughly 50% of C-ALCL patients presented with multiple skin lesions. Both LYP and C-ALCL affected the lower limbs most frequently. Multiplicity and advanced T stage of LYP lesions were associated with a chronic course longer than 6 months. Clinical morphology with patch lesions and elevated serum lactate dehydrogenase were significantly associated with LPDs during follow-up in LYP patients. Extracutaneous involvement of C-ALCL occurred in 13.2% of patients. Lesions larger than 5 cm and increased serum lactate dehydrogenase were associated with a poor prognosis in C-ALCL. The survival of patients with C-ALCL was unaffected by the anatomical locations of skin lesions or other pathological factors. Conclusion The multiplicity or size of skin lesions was associated with a chronic course of LYP and survival among patients with C-ALCL.

Airway management is a fundamental and complex process that involves a sequence of integrated tasks. Situations requiring emergency airway management may occur in the emergency department, intensive care units, and various other clinical spaces. A variety of challenges can arise during emergency airway preparation, intubation, and postintubation, which may result in significant complications for patients. Therefore, many countries are establishing step-by-step systemization and detailed guidelines and/or updating their content based on the latest research. This clinical review introduces the current trends in emergency airway management, such as emergency airway management algorithms, comparison of video and direct laryngoscopy, rapid sequence intubation, pediatric airway management, prehospital airway management, surgical airway management, and airway management education.

Background: Poorly differentiated thyroid carcinoma (PDTC) accounts for a small portion of thyroid carcinomas but contributes to a significant proportion of thyroid carcinoma-associated deaths. The clinicopathological prognostic factors and clinical outcomes of PDTC remain unclear. We aimed to evaluate the clinical outcomes of patients with PDTC after curative treatment. Methods: A comprehensive search was performed up to September 2023. We included studies investigating treatment outcomes in patients with PDTC who underwent initial surgery. The 5-year disease-free survival (DFS) and overall survival (OS) were extracted. In this meta-analysis, the enrolled PDTC histological criteria included 3rd, 4th, and 5th World Health Organization (WHO) and Memorial Sloan Kettering Cancer Center (MSKCC) classification. A random-effects model was used for the pooled proportion analysis. Meta-regression analysis was conducted to evaluate the prognostic factors. Results: Twenty retrospective studies published between 2007 and 2023, including 1,294 patients, met all inclusion criteria. Studies that diagnosed PDTC based on various histological criteria including 3rd WHO (n=5), 4th WHO (n=12), 5th WHO (n=2), and MSKCC (n=1) were included. Overall, 5-year DFS and 5-year OS were 49.4% (95% confidence interval [CI], 42.3 to 56.4) and 73.8% (95% CI, 66.5 to 79.9), with moderate heterogeneity of 58% and 55%, respectively. In meta-regression analysis, extrathyroidal extension (ETE) was a prognostic factor for OS. Conclusion The meta-analysis of DFS and OS in patients with PDTC show the moderate heterogeneity with a variety of histological criteria. ETE appears to have a significant impact on OS, regardless of histological criteria.

Purpose: This study examines the association between child maltreatment and the perpetration and victimization of intimate partner violence (IPV) in adulthood, exploring the moderating effects of gender, age, and household income level. Methods: This cross-sectional study analyzed secondary data from the 2016 Domestic Violence Survey in South Korea, including 1,765 married individuals aged 65 or younger who responded to key variables. Structural equation modeling was used to analyze associations among the variables. Results: The paths from child maltreatment to IPV perpetration (β=.22, p<.001) and victimization (β=.22, p<.001) were statistically significant. Gender, age, and household income level significantly moderated this relationship. Women under 40 were more likely to be IPV victims than perpetrators. Low-income level increased the likelihood of being both perpetrators and victims. Women under 40 who had experienced child maltreatment and had a low-income level showed different probabilities of being victims or perpetrators of IPV. Conclusion Our findings highlight the need to mitigate the negative impact of child maltreatment in adulthood by designing specific interventions for vulnerable groups, such as women, younger individuals, and those with low-income levels. Ensuring lifelong prevention of child maltreatment and establishing tailored programs for IPV is crucial.

Background: The immunological and histopathological understanding of rosacea subtypes remain unclear. This study aimed to characterize erythematotelangiectatic rosacea (ETR), papulopustular rosacea (PPR), and granulomatous rosacea (GR) immunologically through facial punch biopsy samples. Objective: Our goal was to investigate the immunohistochemical profile of rosacea subtypes, providing insights into pathogenesis for targeted therapies. Methods: Biopsy samples from 52 rosacea patients and 25 controls were stained for antibodies retrospectively. Statistical analyses identified expression differences. Results: In the rosacea group (average age, 55.0; male-to-female ratio, 1:2.1), Langerhans cell count, p53, and vitamin D receptor expression showed no differences from controls or among subtypes. Claudin-1 and occludin expression decreased in rosacea compared to controls, with no variance among subtypes. Demodex mites were present in 40.4% of rosacea cases vs. 8.0% in controls (p=0.003), more frequently in PPR than GR, and absent in ETR. Neutrophil elastase expression mirrored the Demodex pattern. The CD4/CD8 ratio averaged 2.15 in rosacea without differences among subtypes. CD20 and CD68 expression increased in rosacea, escalating in the order of ETR, PPR, and GR, mirroring matrix metalloproteinase-2 (MMP-2). ETR exhibited insignificant CD20 and MMP-2 expression. Conclusion Our findings validate a CD4＋ T cell-driven response across all rosacea subtypes. Increased neutrophils, B cells, and macrophages, likely influenced by Demodex, were observed in PPR and GR. Demodex mites may recruit additional B cells and macrophages, potentially linked to MMP-2 expression. This comprehensive characterization offers additional insights into the immunopathogenesis of rosacea, paving the way for targeted interventions.

Zipper entrapment injuries require a technique to safely and promptly release the entrapped tissues to prevent complications. Herein, we report an 8-year-old girl whose eyelid wassuccessfully released from an entrapping zipper. She presented to the pediatric emergency department with her right upper eyelid entrapped in a zipper while getting dressed. Shewas distressed, anxious, and crying in pain. We have successfully removed the zipper using a lubricating gel, which provides local anesthesia. This case report will increase emergencyphysicians’ awareness of the technique of removing an entrapped zipper on the eyelid using a lidocaine gel.

Thyroid hormone resistance (RTH) is characterized by a decreased sensitivity of target tissues to thyroid hormones due to a defect in the THRα- and THRβ-encoded thyroid hormone receptors (THRs). The clinical manifestations range from no symptoms to simple goiter and hypo- or hyperthyroidism, depending on the receptor subtype distribution in the tissues. Here, we report the case of a thyroid hormone-resistant 12-month-old boy carrying a novel THRβ variant who was initially diagnosed with congenital hypothyroidism. An extensive evaluation revealed increased free T4 level and inappropriately increased thyroid-stimulating hormone (TSH) level; a normal lipid profile, sex hormone-binding globulin, and free alpha subunit of TSH; exaggerated TSH response to THR; and no radiological evidence of pituitary adenoma. A targeted next-generation sequencing panel identified a heterozygote c.993T>G (p.Asn331Lys) mutation in the THRβ gene. During the first year of life, a higher dose of levothyroxine was administered to the patient due to uncompensated RTH. Levothyroxine treatment was continued after 3 years to maintain TSH level <5 mIU/mL, but the observed weight gain was poor, height increase was insufficient, and bone development was delayed. However, neither hyperactivity nor developmental delay was observed. Patients with RTH exhibit various clinical features. Due to its heterogeneous nature, genetic test for accurate diagnosis is important to provide proper management.

Purpose: The purpose of this study was to examine the effects of a multidisciplinary program for relapse prevention on abstinence self-efficacy, impulsivity and suicidal ideation among patients with substance use disorder Methods: A nonequivalent control group non-synchronized design was used. The participants were 42 substance addicted patients admitted to the addiction ward. The study variables of abstinence self-efficacy, impulsivity, and suicidal ideation were evaluated by the x2 test, Kolmogorov-Smirnov test, Shapiro-Wilk test, Mann-Whitney U test using the SPSS program. Results: The experimental group showed a significant difference in abstinence self-efficacy (U=54.50, p<.001), impulsivity (U=88.00, p<.001) and suicidal ideation (U=77.50, p<.001) compare to the control group. Conclusion The multidisciplinary relapse prevention program was effective in improving abstinence self-efficacy, impulsivity, and suicidal ideation. It is essential to develop optimal nursing interventions for patients with substance use disorders to prevent relapse.
