BACKGROUND AND OBJECTIVES: Stroke onset is known to vary by several factors. Although it has been known that stroke may develop most frequently in the morning, its association with the type of activity has quite rarely been described. METHODS: We prospectively investigated by interview the time of and the activity during or before the onset of stroke in patients with acute cerebral infarction from Aug. 1995 to Mar. 1996. The activities were subdivided into basal metabolic rate state, sedentary, light, moderate, and heavy movements based on the caloric expenditure. RESULTS: One hundred-twenty five patients were enrolled. The time of day when ischemic stroke most frequently occurred was from 8:00 AM to noon. The type of activity was significantly associated with stroke onset in that it developed most commonly during and just after sleep or resting. The relationship between the onset of stroke and such patterns of onset time and the activity was found only in the atherothrombotic infarction, but not in the other stroke types. CONCLUSION: We demonstrated that stroke has clear diurnal variation. Our observations also suggested that the activity may be significantly associated with stroke onset. These findings may be useful for better understanding of the pathogenesis and prevention of ischemic stroke.

PURPOSE: As the mobile internet spread, patients can access to health information via mobile applications. But this information must be a reliable for treatment. This study evaluated the quality of information of mobile applications that with atopic dermatitis. METHODS: On April 2014, the 98 mobile applications that had been searched on three application markets using the keywords, 'atopic dermatitis' etc. were enrolled. Thirty-one applications with information about atopic dermatitis written in Korean were surveyed. The informational quality of each application was examined using DISCERN tool and we also examined authorship, price, number of downloads. And we analyzed relations between these factors and informational quality. RESULTS: The mean score (+/-standard deviation) of overall rating of the publications of the 31 applications were 1.55 (+/-0.888) points. The overall quality of the publication was 'low' in 80.6% of applications, 'moderate' in 16.1%, 'high' in 3.2% of the applications we evaluated. There were no significant differences between the score of price of applications in all questions. However the mean score of group of downloads 1,000 and more were 2.25 (+/-1.035), significantly higher than group of downloads less than 1,000, 1.30 (+/-0.703) (P=0.043). CONCLUSION: The quality of mobile applications providing health information on atopic dermatitis needs significant improvement. Some guidelines and certifications of the mobile application are needed to provide health information about atopic dermatitis, association with experts.

BACKGROUND: It is well known that a lacunar infarction may develop by an atherosclerosis of the large intracranial arteries at the site of the perforating arteries. However, their frequency, clinical, and radiological findings have rarely been described. METHODS: Carotid angiograpies were carried out in 26 Korean patients with lacunar infarctions in the carotid arterial territory. They all had classical lacunar symptoms with a computed tomogram (CT) or a magnetic resonance image (MRI) evidence of a small infarction. A transesophageal echocardiography (TEE) was carried out in fifteen patients when either an angiography result was normal, the potential source of cardioembolism was suggested, or no other atherothrom-botic causes of stroke were found. Tc-99m single positron emission computed tomograms (SPECT) were performed in nine patients. We divided patients into two groups; one for patients with MCA occlusive lesion, and another for those without it. The clinical and radiological features were compared between the two groups. RESULTS: Twenty patients (77%) demonstrated abnormal angiographic findings. Fourteen of them showed atherosclerotic changes in the proximal MCA at the site of the orifice of the lenticulostriatal arteries, while another three showed stenosis in the intracranial portion of the internal cerebral artery (ICA), and the other three in the extracranial ICA. Among six patients with normal angiograms, a TEE demonstrated embolic sources of embolism in two patients. The temporal profile and findings of MRI and SPECT in patients with MCA stenosis differed from those with ICA stenosis or normal angiograms. Unstable temporal profiles exclusively occurred in patients with MCA stenosis. The most patients with conglomatory aggregations of the lacune in a MRI showed MCA lesions. The SPECT findings were even more characteristic in that patients with MCA lesions showed relatively large areas of decreased perfusion. CONCLUSIONS: The atherosclerotic diseases at the orifice of the lenticulostri-atal arteries were the most common causes of lacunar infarctions in the carotid artery territory. They were clearly different from those without MCA occlusive lesions in terms of preceding transient ishemic attacks, unstable temporal profiles, uni-lateral multiple lacunes with conglomatory MRI findings, and widespread perfusion defects SPECT.

This study aimed to examine the positive effects of polydeoxyribonucleotide (PDRN) on the wound-healing process in pressure ulcers. In this randomized controlled trial, the effects of PDRN were compared over time between an experimental group (n=11) and a control group (n=12). The former was administered the same dose of PDRN intramuscularly (1 ampule, 3 mL, 5.625 mg, for 5 days) for 2 weeks and perilesionally (1 ampule, 3 mL, 5.625 mg, twice a week) for 4 weeks. The primary endpoint for determining efficacy was wound healing in the pressure ulcers, which was reflected by the wound surface area determined using VISITRAK Digital (Smith & Nephew, Largo, FL). The secondary endpoint was the pressure ulcer scale for healing score, determined using pressure ulcer scale for healing (PUSH Tool 3.0 developed by the National Pressure Ulcer Advisory Panel). After the 4-week treatment period, PDRN therapy was found to significantly reduce the wound size and PUSH score, without adverse effect during the treatment. The findings indicate that PDRN can positively modify the wound healing process in pressure ulcers, and its use could improve the clinical outcomes of patients and lower the need for additional therapies or hospital stay.

Clinical therapy that combines full-mouth rehabilitation with immediate implantation and orthognathic surgery poses a challenge to prosthodontists. This clinical report describes a multidisciplinary approach to the diagnosis and treatment of a patient presenting with skeletal discrepancy and rampant caries. The results thus achieved indicate that full-mouth rehabilitation by fixed immediate and early loading implantation accompanied by orthognathic surgery can be a predictable and effective treatment procedure.

This study examines how acquired capability for suicide, negative urgency, and social support effectuate a suicide attempt. Sixty-three adults having visited an emergency room due to a suicide attempt were studied. The results can be summarized as follows. First, there were no significant sex differences in acquired capability for suicide, negative urgency, and social support. Second, the correlation among suicidal ideation, acquired capability for suicide, negative urgency, social support, and suicide attempts was examined. Results showed that suicide attempts were significantly and positively correlated with suicide ideation, acquired capability for suicide, and negative urgency. However, social support and suicide attempts did not significantly correlate. Third, results of hierarchical regression analysis indicated that acquired capability for suicide and negative urgency significantly predicted suicide attempts even when suicide ideation was controlled, but social support did not significantly explain attempts. In other words, study results imply that suicide attempts increase when acquired capability for suicide and negative urgency are high. Study results offer empirical data for understanding the intrinsic characteristics of individuals attempting suicide.

Castleman disease (CD) is a disorder with distinct lymphoid hyperplasia of unknown origin, and it is rare in children. There are two major forms of CD: unicentric (localized) and multicentric. Pathologically, it can be categorized into three subtypes: hyaline- vascular, plasma cell, and mixed types. We experienced a 15-year-old boy with histopathologically proven mediastinal CD of the plasma cell type. He was referred to our hospital because of mediastinal widening in a chest x-ray found by chance. Surgery was performed to resect two right paratracheal masses and subtotal excision was done. As complete surgical resection was not possible, the patient subsequently received three-dimensional conformal radiation therapy (total 5,400 cGy in 27 fractions). The size of the mass decreased, and his clinical symptoms regressed without any side effects from radiotherapy. Here we report a case of unicentric plasma cell type CD, treated with radiotherapy due to incomplete surgical resection.

PURPOSE: To report the results of a new technique for intraocular lens scleral fixation of temporary haptic externalization and four-point fixation for enhanced stability. METHODS: Two 10–0 polypropylene strands were fixed at two points 2 mm apart on each haptic of a conventional three-piece intraocular lens, using our previously reported method of temporary haptic externalization after injector implantation. Postoperative refractive outcome and stability were evaluated. RESULTS: Although the intraocular lens was fixed at a total of four points, no intraoperative difficulties were observed during the process. Patients showed successful fixation of the intraocular lens postoperatively. The fixed intraocular lens showed good centering and minimal tilting. When compared to the two-point fixation technique, postoperative astigmatism was significantly smaller in the four-point fixation group (1.80 ± 0.84 vs. 1.00 ± 0.0.50, p = 0.033). Lens-induced astigmatism calculated from subtraction of corneal astigmatism from total astigmatism was also significantly smaller in the four-point fixation group (2.23 ± 0.98 vs.1.17 ± 0.0.70, p = 0.043). No postoperative complications were identified during a mean follow-up period of 14.8 months (range, 10 to 19 months). CONCLUSIONS: By fixing the intraocular lens at two points on each side of the haptics, this method minimizes the tilting of the intraocular lens and thus decreases postoperative lens-induced astigmatism. Also, the possibility of intraocular lens dislocation in the long term might be decreased by this two-point fixation technique.
