Background:
Chromosomal alterations serve as diagnostic and prognostic markers in acute leukemia. Given the evolving landscape of chromosomal abnormalities in acute leukemia, we previously studied these over two periods. In this study, we investigated the frequency of these abnormalities and clinical trends in acute leukemia in Korea across three time periods.
Methods:
We retrospectively analyzed data from 1,787 patients with acute leukemia (319 children and 1,468 adults) diagnosed between 2006 and 2020. Conventional cytogenetics, FISH, and multiplex quantitative PCR were used for analysis. The patient groups were divided according to the following three study periods: 2006–2009 (I), 2010–2015 (II), and 2016–2020 (III).
Results:
Chromosomal aberrations were detected in 92% of patients. The PML::RARA translocation was the most frequent. Over the 15-yr period, chromosomal aberrations showed minimal changes, with specific fusion transcripts being common among patients.ALL was more prevalent in children than in adults and correlated significantly with the ETV6::RUNX1 and RUNX1::RUNX1T1 aberrations. The incidence of ALL increased during the three periods, with PML::RARA remaining common.
Conclusions
The frequency of chromosomal abnormalities in acute leukemia has changed subtly over time. Notably, the age of onset of adult AML has continuously increased. Our results may help in establishing diagnoses and clinical treatment strategies and developing various molecular diagnostic platforms.

Background/Aims:
Ischemic colitis (IC), the most common ischemic syndrome affecting the gastrointestinal tract, results from a decreased blood supply to the colon. Persistent symptoms can lead to complications, necessitating surgery. This study assessed the clinical characteristics and risk factors for poor outcomes in IC.
Methods:
This retrospective observational study examined the medical records of 141 patients diagnosed pathologically with IC via surgery or colonoscopy at Chonnam National University Hwasun Hospital between April 2004 and August 2023.
Results:
Eighteen (12.8%) and 123 (87.2%) patients were diagnosed by surgical biopsy and biopsy with colonoscopy, respectively.Multivariate analysis identified right-sided colon involvement, fever, and the absence of hematochezia as risk factors for the progression to surgery (odds ratio [OR]=5.924, 95% confidence interval [CI] 1.009–34.767, p=0.049; OR=24.139, 95% CI 5.209– 111.851, p<0.001; and OR=0.076, 95% CI 0.013–0.446, p=0.004, respectively). The in-hospital mortality was 5.7% (8/141), and the patients who died exhibited higher rates of shock. The median (interquartile range) hospital stay was 11 (1–219) days. Patients who had longer hospital stays (≥14 days) had a significantly higher rate of fever but a lower rate of hematochezia.
Conclusions
A multidisciplinary approach is crucial for determining the need for surgery in patients with right-sided colon involvement, fever, or the absence of hematochezia.

The occurrence of an abdominal wall hematoma caused by abdominal paracentesis in patients with liver cirrhosis is rare. This paper presents a case of an abdominal wall hematoma caused by abdominal paracentesis in a 67-year-old woman with liver cirrhosis with a review of the relevant literature. Two days prior, the patient underwent abdominal paracentesis for symptom relief for refractory ascites at a local clinic. Upon admission, a physical examination revealed purpuric patches with swelling and mild tenderness in the left lower quadrant of the abdominal wall. Abdominal computed tomography revealed advanced liver cirrhosis with splenomegaly, tortuous dilatation of the para-umbilical vein, a large volume of ascites, and a large acute hematoma at the left lower quadrant of the abdominal wall. An external iliac artery angiogram showed the extravasation of contrast media from the left deep circumflex iliac artery. Embolization of the target arterial branches using N-butyl-2-cyanoacrylate was then performed, and the bleeding was stopped. The final diagnosis was an abdominal wall hematoma from the left deep circumflex iliac artery after abdominal paracentesis in a patient with liver cirrhosis.

Korean Journal of Dermatology 2023;61(7):420-428
Background:
Dermatophyte infection is one of the most common skin diseases affecting the skin, hair, and nails. Despite widespread recognition of the disease, missing details and misperceptions are commonplace in the general population.
Objective:
This study aimed to investigate the public perception and behavior regarding dermatophytosis of the hands and feet.
Methods:
This results from an online survey conducted between July 2022 and August 2022. The survey included 1,000 Korean participants aged 20 to 69 years, of whom 60% experienced symptoms of tinea pedis or onychomycosis. The questionnaire focused on the awareness and personal experience of tinea pedis and perception of the treatment of dermatophytosis.
Results:
Of the 1,000 participants, nearly 80% regarded tinea pedis as a common skin condition by which anyone can be affected. Furthermore, 88.4% had heard that the treatment of tinea pedis could be harmful, causing skin rash (60.4%) and worsening liver function (48.5%). Among 896 participants who noticed suspicious symptoms, 81.2% did not visit the clinic because it was not severe (50.1%) and seemed easily manageable (25.7%). Of the respondents, 84.4% preferred to meet dermatologists rather than non-dermatologist doctors regarding skin diseases, mainly because of trust in experts and belief in a faster cure.
Conclusion
Providing accurate and detailed information via online media, educational campaigns, and medical papers can rectify misconceptions and improve patient appliance, contributing to public skin health.

Mucosal environments harbour lymphocytes, which express several adhesion molecules, including intestinal homing receptors and integrin αE/β7 (CD103). CD103 binds E-cadherin, an integrin receptor expressed in intestinal endothelial cells. Its expression not only enables homing or retention of T lymphocytes at these sites but is also associated with increased T lymphocyte activation. However, it is not yet clear how CD103 expression is related to the clinical staging of breast cancer, which is determined by factors such as the size of the tumor (T), the involvement of nearby lymph nodes (N), and presence of metastasis (M). We examined the prognostic significance of CD103 by FACS in 53 breast cancer patients and 46 healthy controls enrolled, and investigated its expression, which contributes to lymphocyte recruitment in tumor tissue. Patients with breast cancer showed increased frequencies of CD103+ , CD4+ CD103+ , and CD8+ CD103+ cells compared to controls. CD103 was expressed at a high level on the surfaces of tumor-infiltrating lymphocytes in patients with breast cancer. Its expression in peripheral blood was not correlated with clinical TNM stage. To determine the localisation of CD103+ cells in breast tissue, tissue sections of breast tumors were stained for CD103. In tissue sections of breast tumors stained for CD103, its expression in T lymphocytes was higher compared to normal breast tissue. In addition, CD103+ cells expressed higher levels of receptors for inflammatory chemokines, compared to CD103 − cells. CD103+ cells in peripheral blood and tumor tissue might be an important source of tumor-infiltrating lymphocyte trafficking, homing, and retention in cancer patients.

Purpose:
This study aimed to identify the effect of warm scarf on xerostomia and sore throat in postoperative colon cancer patients.
Methods:
A total of 40 participants with colon cancer who underwent colon cancer operation over 2hours were included from C University hospital in Seoul. The number of experimental group and control group is each 20 calculated by G*Power, and they were assigned by using nonequivalent control group no-synchronized design. In the experimental group, a warm scarf was applied to the neck for 120 minutes from entering the recovery room after the colorectal cancer surgery was completed. In the experimental group and the control group, xerostomia and sore throat were measured twice at 60-minute intervals. The degree of xerostomia was measured through the degree of wetness of the absorbent paper in mm, and the degree of sore throat was measured through the NRS (Numeral Rating Scale). Data were collected using self-administered questionnaires from August 2018 to September 2020 and were analyzed using IBM SPSS/WIN 21.0 Descriptive statistics, x2 test, Fisher's exact test, t-test were used to determine the participant's characteristics. The effect of warm scarf on xerostomia and sore throat were separately estimated by Repeated Measures ANOVA.
Results:
The experimental group showed significant decrease of xerostomia and sore throat as time goes (p<.001).
Conclusion
Results indicate that warm scarf on xerostomia and sore throat in postoperative colon cancer patients is helpful method for relieving side effect of tracheal intubation.
