PURPOSE: This study was done to evaluate nursing guidelines for patients with acute stroke, developed by adapting the guidelines of Registered Nurses Association of Ontario, Canada to clinical settings on a large scale and evaluating the effectiveness as a research study. METHOD: The general characteristics of the 319 patients and the effectiveness of guideline application were evaluated in terms of structure, process, and outcome using questionnaires on the guidelines application with reference to the medical records of patients with acute stroke hospitalized on a ward of the stroke center of S General Hospital in Seoul. RESULTS: Structures as a guidance system for assessment were consistent with the recommendations. With respect to the process of the guidelines, for items on nursing assessment, improved performance was found to be statistically significant. For outcomes of the guidelines, complications occurred in 8 patients (5.3%) prior to application of the guidelines and 11 patients (6.5%) after application of the guidelines, but this result was not statistically significant (p=.841). CONCLUSION: The results of the study indicate that for the effectiveness of the guidelines, accessibility to the guidelines and effectiveness of quality improvement need to be evaluated, in addition to complications of a stroke.

Intercostal schwannomas are uncommon, encapsulated neoplasms that originate in nerve sheaths of intercostal nerves. They account for less than 10% of primary neural tumors of the chest wall. Herein, we report a pathologically confirmed case of intercostal schwannoma with typical magnetic resonance imaging findings.

Eosinophilia occurs commonly in many diseases including allergic diseases and helminthic infections. Toxocariasis has been suggested as one cause of eosinophilia. The present study was undertaken to examine the prevalence of toxocariasis in patients with eosinophilia and to identify the risk factors for toxocariasis. This prospective cohort study recruited a total of 81 patients with eosinophilia (34 males and 47 females) who visited the outpatient clinic at Seoul National University Hospital from January 2017 to February 2018 and agreed to participate in this study. The prevalence of toxocariasis was examined by T. canis-specific ELISA, and the various risk factors for toxocariasis were evaluated by a questionnaire survey. Among 81 patients with eosinophilia, 18 were positive for anti-T. canis antibodies (22.2%); 88.9% were male (16/18) and 11.1% were female (2/18). Multivariate statistical analysis revealed that males (OR 21.876, 95% CI: 1.667-287.144) with a history of consuming the raw meat or livers of animals (OR 5.899, 95% CI: 1.004-34.669) and a heavy alcohol-drinking habit (OR 8.767, 95% CI: 1.018-75.497) were at higher risk of toxocariasis in patients with eosinophilia. Toxocariasis should be considered a potential cause of eosinophilia when the patient has a history of eating the raw meat or livers of animals in Korea. A single course of albendazole is recommended to reduce the migration of Toxocara larvae in serologically positive cases with eosinophilia.

BACKGROUND: Obesity induced by high-fat diet (HFD) is one of the most widespread metabolic disorders in current society. However, there has been little research regarding the effects of HFD-induced obesity in the septa of animal models of cerebral ischemia. Therefore, in the present study, we investigated septal effects of HFD on neuronal damage and gliosis induced by transient cerebral ischemia. METHODS: Body weight, blood glucose levels and serum lipid profiles levels were measured both in the normal diet (ND) and HFD-group. We also investigated the effects of ND and HFD on neuronal damage and gliosis in the septum after transient cerebral ischemia using immunohistochemistry. RESULTS: The levels of blood glucose, serum triglyceride, and total cholesterol were significantly increased in the HFD-fed gerbils compared with the ND-fed gerbils, although body weight was not significantly changed after HFD feeding. In the ND-fed gerbils, ischemia-induced neuronal damage was found in the septohippocampal nucleus (SHN) of the septum 7 days after ischemia. In the HFD-fed gerbils, ischemia-induced neuronal damage in the SHN was much more severe compared with that of the ND-fed gerbils 4 and 7 days after ischemia. In addition, we found that ischemia-induced glial activation including astrocytes and microglia was accelerated and exacerbated in the HFD-fed gerbils compared with that in the ND-fed gerbils. CONCLUSION: These results indicate that HFD can lead to much more severe effects in ischemia-induced neuronal damage/death in the septum after ischemia-reperfusion, and that it may be associated with accelerated change in glial activation.

Melatonin affects diverse physiological functions through its receptor and plays an important role in the central nervous system. In the present study, we compared immunoreactivity patterns of arylalkylamine N-acetyltransferase (AANAT), an enzyme essential for melatonin synthesis, and melatonin receptor type 1B (MT2) in the spinal cord of young adult (2~3 years) and aged (10~12 years) beagle dogs using immunohistochemistry and Western blotting. AANAT-specific immunoreactivity was observed in the nuclei of spinal neurons, and was significantly increased in aged dog spinal neurons compared to young adult spinal neurons. MT2-specific immunoreactivity was found in the cytoplasm of spinal neurons, and was predominantly increased in the margin of the neuron cytoplasm in aged spinal cord compared to that in the young adult dogs. These increased levels of AANAT and MT2 immunoreactivity in aged spinal cord might be a feature of normal aging and associated with a feedback mechanism that compensates for decreased production of melatonin during aging.
