INTRODUNTION: The objective of the present study was to investigate bedtime, rise time and time-in-bed of Korean college students, separately on weekday and on weekend and to compare them. In addition, this study also aimed to evaluate the influence of gender, age and grade on the above sleep parmeters in Korean college students. METHODS: Information regarding bedtime and rise time, separately on weekday and on weekend, of Korean college students were obtained by self-administered questionnaire. Questionnaires of 1,825 students (1,416 females and 409 males, age 18-30 ; mean age 21.1+/-2.2) were used for statistical analyses. RESULTS: Korean college students retired to bed 50 minutes later (00 : 49 on weekday ; 01 : 40 on weekend ; t=39.67, p<0.001), rose 1 hour 58 minutes later (07 : 52 on weekday ; 09 : 50 on weekend ; t=39.46, p<0.001), and slept 1 hour 8 minutes longer (t=13.33, p<0.001) on weekend. Compared to male students, female students had earlier rise time (t=8.96, p<0.01 ; t=3.89, p<0.01) and earlier bedtime both on weekday and weekend (t=7.10, p<0.01; t=6.04, p<0.01), and shorter time-in-bed on weekday (t=1.99, p<0.01). In addition, rise time delay and time-in-bed increase on weekend were more prominent in female students than in male students (t=3.41, p<0.01 ; t=3.68, p<0.01). Grade was correlated with bedtime and rise time on weekday (beta=0.1022, p<0.01 ; beta=0.1009, p<0.01), bedtime and time-in-bed on weekend (beta=0.1096, p<0.01 ; beta=-0.0990, p<0.01), and differences between weekday and weekend of the rise time and the time-in-bed (beta=-0.0906, p<0.01 ; beta=-0.1115, p=0.02). CONCLUSIONS: In this study, Korean college students had earlier bedtime/rise time and shorter time-in-bed on weekday than on weekend. These findings suggest that weekday sleep-wake schedule of Korean college students may be advanced relative to their biological sleep-wake cycle and that this discrepancy may be associated with weekday sleep deprivation. In addition, differences of sleep patterns between weekday and weekend were more prominent in female students and students with lower grade. Therefore, discrepancy between weekday sleep-wake schedule and biological sleep-wake cycle, as well as weekday sleep deprivation, might be more serious in female or lower-grade students.

Strumal carcinoma of the ovary is rare tumor of germ cell origin characterized by intimate mixture of thyroid tissue and carcinoid. We report a strumal carcinoid tumor associated with ipsilateral follicular cyst and contralateral mature cystic teratoma of the ovary in a 47-year-old woman. Histologically it was composed largely of trabeculae partly of insular carcinoid and focally of individual thyroid follicles. Many cells in the carcinoid areas and even some follicular areas contained abundant argyrophile granules, and they also, in the corresponding areas, demonstrated thyroglobulin. Electron microscopic findings revealed abundant neurosecretory granules and colloid material in the same cell. We agree that this tumor is derived from hybrid showing thyroid and neuroendocrine differenciation.

We report a rare case of primary glomerular disease with both features of IgA nephropathy and membranous glomerulonephritis in a 27 year-old woman with nephrotic syndrome. Histologically, glomeruli showed slight mesangial expansion, proliferation of mesangial cells, and short subepithelial spikes on capillary wall. Direct immunofluorescence demonstrated granular IgG and C3 deposits along the capillary walls, and IgA with C3 deposits in mesangium. Granular subepithelial and rnesangial deposits were observed by electron microscopy. The patient showed complete remission after 6 months therapy with steroid and ACE inhibitor.

Studies for diagnostic analysis using three-dimensional (3D) CT images are recently in progress and needs for 3D craniofacial analysis are increasing in the fields of orthodontics. It is especially essential to analyze the facial soft tissue after orthodontic treatment and orthognathic surgery. In this study 3D CT images of adults with normal occlusion were taken to analyze the facial soft tissue. Norms were obtained from CT images of adults with normal occlusion (12 males, 11 females) using a computer program named V works 4.0 program. 3D coordinate planes were established using soft tissue Nasion as the reference point and a total of 20 reproducible landmarks of facial soft tissue were obtained using the multiple reconstructive sectional images (axial, sagittal and coronal images) of the V works 4.0 program; soft tissue Nasion, Pronasale, Subnasale, Upper lip center, Lower lip center, soft tissue B, soft tissue Pogonion, soft tissue Menton, Endocanthion (Rt/Lt), Alare lateralis (Rt/Lt), Cheilion (Rt/Lt), soft tissue Gonion (Rt/Lt), Tragus (Rt/Lt), and Zygomatic point (Rt/Lt). According to the established landmarks and measuring method, the 3D CT images of adults with normal occlusion were measured and the normal positional measurements and their Net (sigma=root(x2 + y2 + z2)) values were obtained using V surgery program. In the linear measurement between landmarks, there was a significant difference between males and females except Na'-Sn and En(Rt)-En(Lt). The normal ranges of Na'-Zy, Na'-Ch and Na'-Go' (facial depth) were obtained, which was difficult to measure by two-dimensional (2D) cephalometric analysis and facial photographs. These data may be used as references for 3D diagnosis and treatment planning for patients with malocclusion and dentofacial deformity.

This study assessed the impact of distancing measures during the COVID-19 pandemic on cancer diagnostic activities, including gastrointestinal endoscopy (GIE). It analyzed GIE volumes from 2020 to 2022 in comparison to 2018-2019, considering variations in resilience linked to socioeconomic status (SES). The analysis utilized data from the Korean Health Insurance Review and Assessment Services database, covering the entire population and medical facilities. Diagnostic GIE rates (2018-2022) in Gwangju Metropolitan City and Jeonnam province were examined, comparing age-standardized rates (ASRs) by area, gender, and SES. The results indicated a decline in ASRs for colonoscopy and endoscopic gastroduodenoscopy (EGD) in 2020 compared to 2018-2019, followed by an increase in 2021-2022, except for EGD in the medical aid population.SES based and rural-urban disparities were evident in the recovery of GIE rates. The findings suggest that equity-focused strategies are needed to ensure equitable healthcare access among different socioeconomic groups after pandemic.

BACKGROUND/AIMS: Immune thrombocytopenic purpura (ITP) is an autoimmune disease that is mediated by anti-platelet antibodies. Based on the pathogenesis of ITP we evaluated the efficacy of intravenous anti-D immunoglobulin for adult chronic ITP. METHODS: Fourteen patients (4 without splenectomy and 10 with splenectomy) with refractory chronic ITP were treated with 50-70 microgram/kg of intravenous anti-D immunoglobulin only once. Treatment effects were evaluated by measuring the platelet counts and hemoglobin levels. RESULTS: Five patients (36%) showed a response; improvement in the platelet count lasted for on average 7 days (range: 2~24 days). There were no serious adverse effects. CONCLUSION: Anti-D immunoglobulin, which is associated with an Fc receptor blockade, appeared to be safe and effective for the treatment of adults with chronic ITP. Further studies are needed to confirm these findings and define further potentially effective treatment protocols with intravenous anti-D immunoglobulin.

Breast surgery is a common procedure performed in women. Many women who undergo breast surgery suffer from ill-defined pain syndromes. A nerve block is used in the treatment of the acute and chronic pain, but the effectiveness of the treatment has been limited because of its short duration. Recently, the advent of pulsed radiofrequency lesioning (PRF) has proved a successful treatment for chronic refractory pain involving the peripheral nerves. We experienced a case of a 52-year-old female patient complaining of chronic breast neuropathic pain after breast reduction, which was relieved after PRF lesioning of the 4th thoracic spinal nerve and its root.
