Plastic bronchitis is a rare disorder characterized by the formation of extensive, obstructing endobronchial casts. It is associated with asthma and complex cardiac defects such as those requiring the Fontan procedure. The treatment of plastic bronchitis comprises conventional therapy involving spontaneous expectoration and bronchoscopic removal and specific therapy with several new drugs. Herein, we describe the cases of 2 patients diagnosed with plastic bronchitis accompanied with a different underlying disease, which were treated with inhaled corticosteroid and low-dose oral clarithromycin.

We had an opportunity to evaluate a child who developed fever approximately two to three weeks after the open heart surgery for tetralogy of Fallot. His peripheral blood smear showed rings and various stages of Plasmodium vivax. The patient had received packed red blood cells during the surgery and postoperative care, one unit of which was later proved sero-positive for malaria. The possibility of malaria should be included in the differential diagnosis of the patients with unexplained fever after multiple blood product transfusions for the open heart surgery.

The related factors of the quality of life (QOL) in stroke patients was identified empirically. The subjects were 254 stroke patients who were discharged and taken follow-up care at the outpatient department. In this model, the physical, psychological, and social status were assumed to affect the QOL. And the social support was assumed to moderate these effects. NIH stroke state, ADL, and IADL were used to measure the physical status. Using CES-D, the psychological status was measured. The social status was defined as the job change after stroke attack. The satisfaction with the care by primary caregivers, significant others, and health professionals was measured as the social support. To identify the effect of the physical, psychological, and social status on the QOL, multiple regression analysis was carried out. The psychological and social status were found to be the significant predictors of the QOL(R2=0.27, p=0.00). Next, to identify the moderating effect of the social support, the subjects were divided into two groups, that is, the low social support group and the high social support group. It is found that the predicting variance is different between these two groups. In the low social support group, the psychological, social, and physical status predicted as much as 42% of the QOL. On the contrary, the psychological status predicted only 8% of the QOL in the high social support group. So it is concluded that the social support moderates the effects of the physical, psychological, and social status on QOL. Finally, to identify the social support which moderates those effects, the social support was divided into three classes. Each social support class was divided into the low and high social support group again. In the every class of social support, the difference between two groups was also identified. So the model of the QOL is recommended for the framework of the care for the stroke patients. Also these results support the claim that the long-term facilities for stroke patients are necessary.

To determine the spectral pattern of metabolites in 31 brain tumors in which the presence of lipids, lactate and additional intermediary metabolites had been detected, in vivo 1H-MR spectroscopy was performed. Metastasis (n=3), meningioma(n=7), astrocytic tumors of different grades(n=11), postop recurrent tumors(n=2) and other tumors(n=10) were examined using the stimulated echo(STEAM, TE=30ms) or double spin echo technique(PRESS, TE=272ms) with CHESS pulse for water suppression. The detection of lactate in astrocytic tumors correlated with a higher grade of malignancy, and lipid was observed in most glioblastomas. Elevated lactate levels in tumors do not simply originate in the necrotic region, but are related to the high glycolytic activity of adequately perfused, viable neoplastic cells. Lipid signals were detected in high grade, late stage brain tumors, indicating the need for enhanced phospholipid metabolism and membrane degradation, respectively. The absence of lactate and presence of alanine, glutamate/glutamine in most meningiomas distinguished them from schwannomas and other glial tumors. Observation of the spectral pattern of metabolites in brain tumors in which lipid and lactate has been detected might play an important prognostic role in the management and differentiation of metastasis, glial tumors, tumor recurrence, and other non-neoplastic diseases.

The purpose of this study was to describe the perceived burden of the stroke patient's caregiver and related factors to analyze relationships between perceived burden and social supports. A convenient sample of 225 caregivers who take care for a stroke patient at home participated in this study. Caregiver's perceived burden was measured by the objective and subjective burden scale developed by Montgomery (1985). Related factors of burden were studied in terms of the patient's instrumental activties of daily living, cognitive function, caregiver's demographic variables and caregiver's illness intrusiveness. The results were as follows: (1) The mean of objective burden score was 4.5, and subjective burden score was 3.1. These scores show that caregivers perceive moderate level of burden. (2) Caregivers' objective burden was significantly related to caregivers's illness intrusiveness (r=.62), patient's IADL (r=-.33), and patient's cognitive function (r=-.15). The subjective burden was related to the caregiver's illness intrusiveness (r=.29), the patient's IADL (r=.24), and the caregiver's age(r=.23). (3) The percentage of stroke caregivers who perceived physical support was 49.1%. The percentage of those who perceived emotional support was 61.0%, and those who perceived financial support totaled 37.6%. (4) Caregivers who received any type of social supports perceived lower subjective burden, and caregivers who received physical or psychological support perceived lower objective burden. These results emphasized the necessity of a rehabilitation programs for stroke patients and support program for family caregivers.

BACKGROUND: Bone cancer pain has a disruptive effect on the cancer patient's quality of life. Although ginsenosides have been used as traditional medicine in Eastern Medicine, the effect on bone cancer pain has not been thoroughly studied. The aim of this study was to determine whether ginsenosides may alter the bone cancer pain at the spinal level. METHODS: NCTC 2472 tumor cells (2.5 x 10(5)) were injected into the femur of adult male C3H/HeJ mice to evoke bone tumor and bone cancer pain. To develop bone tumor, radiologic pictures were obtained. To assess pain, the withdrawal threshold was measured by applying a von Frey filament to the tumor cells inoculation site. The effect of intrathecal ginsenosides was investigated. Effect of ginsenosides (150, 500, 1,000 microgram) was examined at 15, 30, 60, 90, 120 min after intrathecal delivery. RESULTS: The intrafemoral injection of NCTC 2472 tumor cells induced a radiological bone tumor. The withdrawal threshold with tumor development was significantly decreased compared to the sham animals. Intrathecal ginsenosides effectively increased the withdrawal threshold in the bone cancer site. CONCLUSIONS: NCTC 2472 tumor cells injection into the mice femur caused bone tumor and bone cancer pain. Intrathecal ginsenosides attenuated the bone cancer-related pain behavior. Therefore, spinal ginsenosides may be an alternative analgesic for treating bone cancer pain.

PURPOSE: The inhibition of phosphodiesterase 5 produces an antinociception through the increase of cyclic guanosine monophosphate (cGMP), and increasing cGMP levels enhance the release of gamma-aminobutyric acid (GABA). Furthermore, this phosphodiesterase 5 plays a pivotal role in the regulation of the vasodilatation associated to cGMP. In this work, we examined the contribution of GABA receptors to the effect of sildenafil, a phosphodiesterase 5 inhibitor, in a neuropathic pain rat, and assessed the hemodynamic effect of sildenafil in normal rats. MATERIALS AND METHODS: Neuropathic pain was induced by ligation of L5/6 spinal nerves in Sprague-Dawley male rats. After observing the effect of intravenous sildenafil on neuropathic pain, GABAA receptor antagonist (bicuculline) and GABAB receptor antagonist (saclofen) were administered prior to delivery of sildenafil to determine the role of GABA receptors in the activity of sildenafil. For hemodynamic measurements, catheters were inserted into the tail artery. Mean arterial pressure (MAP) and heart rate (HR) were measured over 60 min following administration of sildenafil. RESULTS: Intravenous sildenafil dose-dependently increased the withdrawal threshold to the von Frey filament application in the ligated paw. Intravenous bicuculline and saclofen reversed the antinociception of sildenafil. Intravenous sildenafil increased the magnitude of MAP reduction at the maximal dosage, but it did not affect HR response. CONCLUSION: These results suggest that sildenafil is active in causing neuropathic pain. Both GABAA and GABAB receptors are involved in the antinociceptive effect of sildenafil. Additionally, intravenous sildenafil reduces MAP without affecting HR.

PURPOSE: This study was conducted to identify better methods of determining the severity of triage by comparing triage results and clinical outcome of patients categorized by the modified Canadian Triage Acuity Scale (mCTAS) and modified Emergency Severity Index (mESI). METHODS: Subjects enrolled in this study consisted of 1,000 adult patients (age 16 years or older) who visited the emergency room of a university affiliated hospital between September 15, 2011 and September 30, 2011 and were categorized into five levels by mCTAS and mESI. RESULTS: 1) Good confidence was verified based on weighted kappa values of 0.70 between the physicians group and nurses group. 2) Upon evaluation of triage by mESI, the majority of patients were at level 3 among 5, followed by level 4, 2, 1 and 5 in order. The same level orders were shown upon evaluation of triage by mCTAS beside differences in patient numbers. 3) Comparing clinical outcome according to the mCTAS and the mESI revealed similar results in both triage tools, with a higher triage level being associated with a higher admission rate and lower triage level and the discharge rate became higher. CONCLUSION: Triage by mESI showed good agreement among asserters and high agreement between physicians and nurses. Clinical results based on mCTAS and mESI triage showed similar rates of admission to the ward or intensive care unit and rates of discharge. Although these two triage protocols are similar in many aspects, the use of mESI is perceived as a better because mCTAS requires knowledge of various diseases and mESI has a short training period.

Even though pleomorphic adenoma is the most common benign tumor of the major salivary gland, such as the parotid gland, it is relatively rare in the minor salivary gland since it accounts for only 10% of all reported pleomorphic adenoma. The minor salivary gland spreads throughout the oral cavity from nasopharynx, oropharynx, to larynx, and pleomorphic adenoma can be possibly found in every one of them. However, pleomorphic adenoma of the larynx is very rare. We experienced a case of 59 year old woman who presented 3 months history of voice change, swallowing difficulty. She had huge pleomorphic adenoma originated from arytenoid area of larynx. We resected the mass by suprahyoid approach and obtained good postoperative results. We reporte this case with a review of literature.
