BACKGROUND: The red cell distribution width(RDW) has been reported to be of value in discriminating iron deficiency anemia(IDA) from the anemia of the other causes(non-IDA). The combination of a low MCV and a high RDW may indicate iron deficiency anemia. The purpose of this study was to discriminate IDA from anemia, using automated blood cell count alone. METHODS: We collected 139 cases of anemia in outpatients, with 80 cases of IDA and 59 cases of anemia due to other causes, from July 1995 to September 1996 in department of family medicine, Pusan Paik hospital. RESULTS: The sex distribution was 39(28.1%) in male, 100(71.9%) in female. The age distribution was 15 to 79 year. The hemoglobin level and MCV in IDA(9.5+/-1.6g/dl, 77.5+/-8.9fl) was significantly lower than those in non-IDA(10.1+/-1.5g/dl, 87.6+/-10.5fl)(P=0.042, P<0.001, respectively). And mean RDW in IDA(16.9+/-3.3%) was significantly higher than that in non-IDA(15.1+/-3.2%)(P<0.001). In discriminating IDA from anemia, we drew receiver operating characteristic curves (ROC curves) with each value of MCV and RDW. The cut-off value of MCV was 83fl, and in that value, the sensitivity and specificity were 75.9% and 72.9%, respectively. The cut-off value of RDW was 14.3%, and the sensitivity and specificity were 78.2% and 57.6 %, respectively. We combined each value of MCV with RDW, the cut off value were 83fl of MCV and 14.3% of RDW, and the sensitivity and specificity were 76.3% and 71.3%, respectively. CONCLUSIONS: The sensitivity and specificity of MCV, RDW and combination of MCV and RDW were not so high in discriminating IDA from the anemia of the other causes in ambulatory patients.

Purpose:
The purpose of this study is three-fold: 1) to evaluate factors influencing hearing aid (HA) satisfaction; 2) to provide a profile of HA satisfaction in daily life; and 3) to examine the reasons why people gave up using HAs.
Materials and Methods:
Data for 1148 respondents were statistically analyzed and reported.
Results:
In the study, age (β=-0.03, p<0.01), level of education (β=1.21, p<0.01), HA purchase price (β=1.50, p<0.01), bilateral amplification (β=1.23, p<0.01), wearing time (β=0.28, p<0.01), and HA fitting and fine tuning on a regular basis (β=1.71, p<0.01) significantly influenced HA satisfaction. In addition, the authors observed that the most satisfactory factors were clarity of sound (53.5%), people’s trust in their HA (61.7%), and listening from a quiet environment (72.8%) in the domains of sound quality, HA features, and listening environments, respectively. Finally, with multiple choices being possible, 65% of the 40 respondents who no longer used HAs answered that their HAs ended up in a drawer since the background noise was annoying and distracting.
Conclusion
This study is significant in that it is a large-scale multi-center research to comprehensively examine the factors influencing HA satisfaction in South Korea. This data will provide helpful information that could lead to the successful rehabilitation of hearing loss with HAs.

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.

Amebic liver abscess (ALA) has been diagnosed in travelers to endemic areas or in patients with immunosuppression secondary to human immunodeficiency virus infection since the late 1990s. Further, it is a rare disease in Korea. ALA should be considered in patients present with fever and right upper quadrant pain along with a risk of exposure to amebiasis. We report an 82-year-old man with symptoms of fever, gross hematuria and severe renal impairment as having amebic liver abscess complicated with the obstruction of the inferior vena cava. Amebic liver abscess was successfully treated with antibiotics alone. Also, hematuria disappeared and renal dysfunction improved after treatment.

Journal of Korean Medical Science 2022;37(2):e11-
Background:
The purpose of this study was two-fold: 1) to identify differences in the characteristics of adopters and non-adopters of hearing aids (HAs); and 2) to investigate factors influencing the purchase of HA.
Methods:
This study was conducted among 1,464 subjects (818 male and 646 female) with hearing loss. A national face-to-face survey was performed from August 2019 to October 2020 by otologists or HA experts. The questionnaire consisted of three domains:demographic, audiological, and HA-related domains. Multivariate logistic regression analysis was performed after adjusting for degree of hearing loss.
Results:
The mean age of the participants was 70.4 ± 12.2 years. Of the 1,464 respondents, 1,190 (81.3%) had already purchased HA. We identified educational level, household income, hearing loss period, place of HA purchase, and government HA assistance program status as factors influencing HA adoption. Among these factors, third party reimbursement was the most important factor affecting HA purchase intent. The main reasons for not adopting HA were feeling that their hearing was adequate, inability to afford HA, and perceptions that HA are uncomfortable.
Conclusion
Various factors are involved in the purchase of HA, but disabled registration status and third party reimbursement were identified as the most critical factors. In the future, the government should take a more active role in increasing the distribution of HA to patients with hearing loss.

STUDY DESIGN: This retrospective study involved 450 consecutive cases of degenerative lumbar stenosis treated with percutaneous stenoscopic lumbar decompression (PSLD). PURPOSE: We determined the feasibility of PSLD for lumbar stenosis at single and multiple levels (minimum 1-year follow-up) by image analysis to observe postoperative widening of the vertebral canal in the area. OVERVIEW OF LITERATURE: The decision not to perform an endoscopic decompression might be due to the surgeon being uncomfortable with conventional microscopic decompression or unfamiliar with endoscopic techniques or the unavailability of relevant surgical tools to completely decompress the spinal stenosis. METHODS: The decompressed canal was compared between preoperative controls and postoperative treated cases. Data on operative results, including length of stay, operative time, and surgical complications, were analyzed. Patients were assessed clinically on the basis of the Visual Analog Scale (VAS) score for the back and legs and using the Oswestry Disability Index (ODI). RESULTS: Postoperative magnetic resonance imaging revealed that PSLD increased the canal cross-sectional area by 52.0% compared with the preoperative area at the index segment (p<0.001) and demonstrated minimal damage to the normal soft tissues including muscles and the extent of removed normal bony tissues. Mean improvements in VAS score and ODI were 4.0 (p<0.001) and 40% (p<0.001), respectively. CONCLUSIONS: PSLD could be an alternative to microscopic or microendoscopic decompression with various advantages in the surgical management of lumbar stenosis.
