OBJECTIVES : The primary purpose of this study was to investigate the effects of computerized cognitive rehabilitation training on inpatients with schizophrenia in the rehabilitation unit. METHODS : Thirty-eight patients with schizophrenia from the Yongin Mental Hospital Rehabilitation Ward were randomly assigned either to a computerized cognitive rehabilitation group or to a control group. The rehabilitation group received 12 sessions of computerized cognitive rehabilitation training (Cog-Trainer) over 3 months. This training program consisted of ten units, each of which consisted of 3 levels, practice, application, and advanced. Neurocognitive functions were assessed at the beginning and end of the training period. Cognitive measures included Span of Apprehension (SPAN), Continuous Performance Test (CPT), Digit Span, Trail Making Test, and the Stroop Test. RESULTS : Compared to controls, subjects receiving computerized cognitive rehabilitation training experienced a significant improvement in attention, concentration, and working memory. CONCLUSION : These results indicate that computerized cognitive rehabilitation training can contribute to improvement in cognitive function of patients with schizophrenia. Further study to generalize these results is required.

In an era of low fertility, the maternity infrastructure system has collapsed steeply and the number of obstetrically underserved areas has increased. To improve the maternity infrastructure, the Yoon Suk Yeol administration has announced the introduction of an essential medical support policy centered on introducing an additional delivery medical fee. The core of the essential medical policy for labor and delivery is the addition of regional medical fees, safety policy additional fees, and infectious disease-controll policy additional fees to the existing labor and delivery medical fees. The government's delivery medical additional fees will vary according region, with 200% increase in metropolitan cities, 300% increase in nonmetropolitan cities, and an additional 100% increase in the event of an infectious disease outbreak. After analyzing the government's plan to support additional fees, it is estimated that the total delivery expenses will be increased by Korean won (KRW) 236,619,748,266, and KRW 485,872,173 per maternity hospital. Even though this support plan is expected to help maintain maternity hospitals, this plan has limitations in small maternity hospitals in metropolitan cities and maternity hospitals for high-risk pregnant women. This is because the government's support policy is based on the "medical payment system by action," which is less effective in rural maternity hospitals with fewer deliveries and in training hospitals that mainly treat high-risk pregnant women rather than simple deliveries. Additionally, given the expected decline in the number of births in the future, it is estimated that the total delivery medical fees will steadily decline, as will the income per maternity hospital. To maintain a sustainable maternity infrastructure, it is essential to introduce the medical fees for operating a maternity delivery room that can be maintained, the medical fees for high-risk pregnancies, and various salary and protection support policies for obstetricians and nurses in addition to delivery medical fees.

Up to 5% of pregnant females experience chronic hypertension, which is linked to poor pregnancy outcomes, and along with hemorrhage, is considered one of the main causes of maternal morbidity and mortality. The combined occurrence of preeclampsia, cesarean sections, preterm birth, birth weight less than 2,500 g, neonatal unit admission, and perinatal death was higher in females with chronic hypertension. Pregnancy with systolic blood pressure of 140-159 mmHg or diastolic blood pressure of 90-109 mmHg was considered to have mild-to-moderate chronic hypertension. Blood pressure management during pregnancy is a very important issue and is directly related to fetal growth and maternal health. Many studies have reported that antihypertensive therapy during pregnancy halves the incidence of severe hypertension in all types of hypertensive diseases. However, guidelines for optimal blood pressure management goals during pregnancy remain unclear. This is because the benefits to the mother from lowering blood pressure are uncertain, and there is a risk of fetal disorders due to the possibility of reduced uteroplacental blood flow. In light of a recently released CHAP (Chronic Hypertension and Pregnancy) randomized controlled trial, the purpose of this review was to provide a summary of the current recommendations for pregnant females with mild-to-moderate chronic hypertension.

Preeclampsia (PE) is a multisystem disorder that is an important cause of maternal and perinatal deaths. Currently, delivery is the only final treatment for PE. This practice is usually accompanied by premature birth, which inevitably increases neonatal morbidities. Aspirin is a non-selective non-steroidal anti-inflammatory drug that irreversibly inhibits cyclooxygenase enzymes involved in converting arachidonic acid to prostaglandins and thromboxane. Aspirin inhibits thromboxane A2 production via platelet aggregation, thereby increasing the prostacyclin/thromboxane A2 ratio and reducing platelet aggregation. Since the first case report of aspirin’s potential use during pregnancy was reported in 1978, many studies have attempted to confirm the effect of aspirin on PE, and the results have been controversial. However, this preventive strategy is generally accepted in clinical practice. As evidence for aspirin’s prevention of PE has been accumulating, a recent study investigated the effectiveness of aspirin at high doses of 150 mg, which is higher than before. However, there is an ongoing debate about how much aspirin should be used during pregnancy and when to start aspirin therapy. Guidelines for the use of prophylactic aspirin during pregnancy vary slightly among countries and groups. In this article, we review and summarize the evidence regarding the use of aspirin for PE prevention.

Epithelioid hemangioma (EH) is an uncommon, benign vascular tumor of mesenchymal origin. It mainly presents as a tumor with a lytic appearance and septations. However, no case reports have documented the predominantly sclerotic appearance of EH. Here, we present the imaging findings, including X-ray, CT, MRI, and histopathological findings of a 24-year-old female with EH.

This study was carried out in order to determine in vitro biocompatibility of white mineral trioxide aggregate (MTA), and to compare it with that of the commonly used materials, i. e. calcium hydroxide liner (Dycal), glass ionomer cement (GIC), and Portland cement which has a similar composition of MTA. To assess the biocompatibility of each material, cytotoxicity was examined using MG-63 cells. The degree of cytotoxicity was evaluated by scanning electron microscopy (SEM) and a colorimetric method, based on reduction of the tetrazolium salt 2,3 bis {2methoxy 4nitro 5[(sulfenylamino) carbonyl] 2H tetrazolium hydroxide} (XTT) assay. The results of SEM revealed the cells in contact with GIC, MTA, and Portland cement at 1 and 3 days were apparently healthy. In contrast, cells in the presence of Dycal appeared rounded and detached. In XTT assay, the cellular activities of the cells incubated with all the test materials except Dycal were similar, which corresponded with the SEM observation. The present study supports the view that MTA is a very biocompatible root perforation repair material. It also suggests that cellular response of Portland cement and GIC are very similar to that of MTA.

PURPOSE: The purpose of this study was to analyze the characteristic MR findings of childhood metachromatic leukodystrophy. MATERIALS AND METHODS: Five female patients (10--29 months old;mean age, 21.8 months) of biochemically confirmed metachromatic leukodystrophy were included in this study. We evaluated the extent of white matter degeneration, which was shown as high signal intensity on T2-weighted image, and the presence or absence of the enhancement. Result.' All 5 cases showed high signal intensity in periventricular deep white matter and centrum semiovale which were bilateral, symmetric and confluent. Posterior predominace, sparing of subcortical U fibers and immediate periventricular white matter, and the involvement of splenium of corpus callosum were also noted in all cases. There were other manifestations, such as 'tigroid pattern' in centrum semiovale (n=4), the involvement of genu of corpus callosum(n=4), posterior limb of internal capsule(n=4), descending pyramidal tracts (n=3), deep cerebellar white matter(n=1), claustrum(n=2), and diffuse brain atrophy(n=1). In three cases with Gd-infusion, contrast enhancement of the lesion was not seen. CONCLUSION: In childhood metachromatic leukodystrophy, MRI can clearly demonstrate the chracteristic extent of the white matter lesion and other associated findings, facilitating the differential diagnosis from other similar leukodystrophies.
