Lymphomatoid papulosis is a strange disease; clinically benign, histologically malignant. Clinically, it may simulate pityriasis lichenoides et varioliformis acuta. The diagnosis is based on the typical histopathological features suggestive of malignant lymphoma, due to the presence of polymorphous lymphoid infiltrate consisting of small lymphocytes intermingled with conspicuous large atypical cells. We experienced a case of lymphomastoid papulosis in 35-year-old woman. Initially, her skin lesions developed as erythematous papules on the extremities, gradually spreading centrifugally with a tendency to involute slowly without treatment, leaving brown wrinkled surface and shallow ulceration. These skin lesions tended to become worse in warm weather and better in cold weather. At first visit, multiple erythematous grouped, ulcerated papules and nodules are seen. 18 months after first visit, most skin lesions are regressed except 5 erythematous pinhead sized papules on right leg in spite of no treatrnent. Labcratory examiniations of CBC, VDRL, urinatlysis, blood chemistry and chest X-ray were all within normal limits. Histopathologically there were hygerkeratosis, mild acanthosis, exocytosis in epidermis, and numerous lymphoid cells were infiltrated especially on perivascular and periappendegeal area, and many atypical cells showing hyperchromatic nuclei, kidney-shaped nuclei and mitotic figures in dermis.

Discoid meniscus in the knee joint is common. From July 1990 through June 1994, the authors performed arthroscopy on 968 symptomatic knee joints. One hundred and six knees of 102 patients had discoid meniscus. Of the 106 knees, 14(13.2%) cases were associated with other intraarticular anatomic variants. There were 7(6.6%) cases with anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament, and 7(6.6%) cases with anterior transposition of the insertion of the anterior cruciate ligament below the anterior tibial margin like the insertion of the posterior cruciate ligament. Of the 14 patients, the discoid meniscus were reshaped in 11 knees, partially resected in 2 knees, and one patient was treated with repair of a peripheral tear and reshaping. But had no treatment in associated intraarticular anatomic variants. The follow up was done from 24 to 54 months(average 37 months) after surgery. The results were excellent in 8 knees ; good in 4 knees and fair in 2 knees(Ikeuchi scale, 1982) The patients with excellent or good results were satisfied as were the authors, and these anatomical variants other than the discoid meniscus were not related to the patient's symptoms.

We examined trends in obesity among Korean adults, using body mass index (BMI) and waist circumference (WC) as reported in national surveys. Data (10,043 men and 12,758 non-pregnant women) were derived from four waves of the Korea National Health and Nutrition Examination Survey conducted in 1998, 2001, 2005, and 2007. Between 1998 and 2007, the distribution of BMI and WC showed shifts toward the right among men. Mean values of BMI and WC and the corresponding overweight (includes obesity) and obesity prevalences showed increasing trends in men but not in women. Women aged 60+ showed significant increases in obesity measures, including mean BMI and WC, and the associated prevalences. Among women aged 20-39, the prevalence of underweight increased significantly between 1998 and 2007, and BMI showed a decreasing tendency. These time trends in young women were the reverse of the trends in young men. In conclusion, policy efforts to abate overweight and obesity trends need to be exercised among men and older women. In addition, more national studies regarding potential increases in underweight among young women are warranted.

Unmet healthcare is an important indicator for measuring accessibility of healthcare services. We analyzed the following four data from a nationally representative sample of South Korean population: Korea Health and Nutrition Examination Survey (KNHANES, 2007 –2021), Community Health Survey (CHS, 2008–2021), Korea Health Panel Survey (KHP, 2011–2019), and Korean Welfare Panel Study (KOWEPS, 2006–2021). The proportion of individuals reporting unmet healthcare needs were 6.0% (KNHANES), 5.1% (CHS), and 13.1% (KHP). Annual percentage change (APC) which identifies trend for the follow-up period was -9.4%, -9.4%, and -5.3%, respectively. The proportion of individuals reporting unmet healthcare needs due to cost were 1.2% (KNAHANES), 0.5% (CHS), 2.7% (KHP), and 0.4% (KOWEPS). The APC was -10.4%, -16.1%, -11.5%, and -19.1%, respectively. Compared to the previous year, the rate of unmet healthcare needs decreased slightly, but the rate of unmet health care needs due to cost tended to increase. Overall, higher rates of unmet healthcare needs were reported in the low-income and the elderly population. Although it was confirmed through the APC that the rate of unmet healthcare experience has decreased over the past decade, it can be seen that there is still a disparity by income level and age. These results suggest the need for an appropriate health benefit coverage policy for the low-income and the elderly.

Background: Harsh temperature exposure has been associated with a high risk of cardiovascular events. We sought to investigate the influence of temperature change on longterm incidence of acute myocardial infarction (AMI) in Korean patients. Methods: From the National Health Insurance Service (NHIS) customized health information database (from 2005 to 2014), data from a total of 192,567 AMI patients was assessed according to the International Classification of Disease 10th edition code and matched with temperature reports obtained from the Korea Meteorological Administration database. We analyzed data for a 10-year period on a monthly and seasonal basis. Results: The incidence rate per 100,000 year of AMI exhibited a downward trend from 69.1 to 56.1 over the period 2005 to 2014 (P < 0.005), and the seasonal AMI incidence rate per 100,000 year was highest in spring (63.1), and winter (61.3) followed by autumn (59.5) and summer (57.1). On a monthly basis, the AMI incidence rate per 100,000 year was highest during March (64.4) and December (63.9). The highest incidence of AMI occurred during temperature differences of 8–10° in each season. Moreover, AMI incidence tended to increase as the mean temperature decreased (r = −0.233, P = 0.001), and when the mean daily temperature difference increased (r = 0.353, P < 0.001). Conclusion The AMI incidence rate per 100,000 year has a decreasing trend over the 10-year period, derived from the Korean NHIS database. Modest daily temperature differences (8–10°) and the spring season are related to higher AMI incidence, indicating that daily temperature variation is more important than the mean daily temperature.

Cholecystectomy is associated with an increased risk of colorectal cancer, but little is known about the relationship between gallbladder disease and colorectal adenoma. Gallbladder polyps and colorectal neoplasia (CRN) share several risk factors such as obesity, diabetes and metabolic syndrome, which might account for their association. In this study, we investigated whether asymptomatic patients with gallbladder disease are at increased risk of CRN and identified the factors to their association. The study population consisted of 4,626 consecutive, asymptomatic individuals drawn from a prospective health check-up cohort who underwent both ultrasonography and colonoscopy screening. The prevalence of CRNs in patients with gallbladder polyps or gallstones was significantly higher than that in the control group (32.1% vs. 26.8%; P = 0.032, 35.8% vs. 26.9%; P = 0.020). A multivariate regression analysis showed that gallbladder polyps were an independent risk factor for CRN [adjusted odds ratio (OR): 1.29; 95% confidence interval (CI); 1.03-1.62] whereas gallstones were not (adjusted OR: 1.14; 95% CI: 0.79-1.63). The adjusted OR for the risk of CRN was 1.12 for gallbladder polyps < 5 mm (95% CI, 0.85-1.46) and 1.79 for gallbladder polyps > or = 5 mm (95% CI, 1.15-2.77). The prevalence of CRN increased with increasing polyp size (P trend = 0.022). Our results suggest that colorectal neoplasia is significantly related to gallbladder polyps, especially those > or = 5 mm.

PURPOSE: To compare the clinical and anterior segment anatomical features in primary angle closure sub-groups based on configurations of iris root insertion. METHODS: Primary angle closure patients were imaged using anterior segment optical coherence tomography. Anterior chamber depth, iris curvature, iris thickness (IT) at the scleral spur and 500, 750, and 1,500 µm from the scleral spur (IT(0), IT(500), IT(750), and IT(1500)), lens vault, iris area, angle opening distance (AOD(500)), angle recess area (ARA(750)), and trabecular iris space area (TISA(750)) were measured. Iris root insertion was categorized into a non-basal insertion group (NBG) and basal insertion group (BG). RESULTS: In total, 43 eyes of 39 participants belonged to the NBG and 89 eyes of 53 participants to the BG. The mean age of participants was greater in the NBG than the BG (62.7 ± 5.7 vs. 59.8 ± 7.3 years, p = 0.043), and the baseline intraocular pressure was higher in the BG than the NBG (16.4 ± 4.4 vs. 14.9 ± 3.3 mmHg, p = 0.037). The BG showed a greater IT(0) (0.265 ± 0.04 vs. 0.214 ± 0.03 mm, p < 0.001) and iris area (1.59 ± 0.24 vs. 1.52 ± 0.27 mm2, p = 0.045), lower ARA(750) (0.112 ± 0.08 vs. 0.154 ± 0.08 mm2, p = 0.017) and AOD(500) (0.165 ± 0.07 vs. 0.202 ± 0.08 mm, p = 0.014) compared to the NBG. CONCLUSIONS: The BG had a narrower anterior chamber angle, thicker peripheral iris, and higher pretreatment intraocular pressure.

PURPOSE: To explore the progressive change and associated factors of optic disc tilt in young myopic glaucomatous eyes by analyzing long-term follow-up data.METHODS: Optic disc images were obtained from spectral-domain optical coherence tomography enhanced depth imaging from at least five different visits. At each visit, the disc tilt angle (DTA), defined as the angle between the Bruch's membrane opening plane and the optic canal plane, was estimated at the central frame that passes through the optic disc. Glaucoma progression was assessed on the basis of changes noted on serial optic disc and retinal nerve fiber layer photographs or changes in the visual field (VF). A linear mixed effect model was used to assess the influence of parameters (age, sex, baseline and follow-up intraocular pressure, retinal nerve fiber layer thickness, VF mean deviation, axial length, central corneal thickness), and presence of glaucomatous progression upon DTA change.RESULTS: A total of 26 eyes of 26 young myopic primary open-angle glaucoma patients (axial length >24.0 mm; mean age, 25.1 ± 4.0 years; mean follow-up, 3.3 ± 0.9 years) were included. DTA was 7.0 ± 3.4 degrees at baseline and 8.3 ± 3.8 degrees at last visit, which represents a significant difference (p < 0.001). Worse VF mean deviation (p < 0.001) and longer axial length (p = 0.006) were significantly associated with DTA increase.CONCLUSIONS: Young myopic glaucomatous eyes showed progressive optic disc tilting. Progressive optic disc tilting in young myopic glaucomatous eyes may be related to either continuous axial myopic shift or glaucomatous structural change.
