Objective: To investigate the comprehensive outcomes in aphasic patients, including their cognitive and functional status after ischemic or hemorrhagic stroke. It also aimed to clarify whether aphasia is a prognostic factor for cognitive and functional improvements in stroke patients. Methods: Sixty-seven ischemic or hemorrhagic stroke patients in the subacute stage who had been diagnosed with aphasia using the Korean version of Frenchay Aphasia Screening Test (K-FAST) were included in the study. Forty-six stroke patients without aphasia were used as controls. All patients were examined with the Korean version of the Western Aphasia Battery (K-WAB). Cognitive and functional assessments of the patients including the Korean version of Mini-Mental State Examination (K-MMSE), and the Korean version of Modified Barthel Index (K-MBI) were performed during admission and 4 weeks after the initial assessments. Results: The initial and follow-up total K-MMSE and K-MBI scores were significantly lower in aphasic patients than in non-aphasic controls. The K-WAB scores highly correlated with the total K-MMSE scores at the follow-up stage in all aphasic stroke patients. The K-WAB scores moderately correlated with the follow-up scores of the K-MBI in ischemic stroke patients but not in hemorrhagic stroke patients. Conclusion Aphasia influences the cognitive and functional status of stroke patients and has a greater impact on cognitive improvement. Aphasia severity can be one of the prognostic factors for cognitive status in aphasic patients with stroke.

OBJECTIVE: To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI). METHODS: Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated. RESULTS: There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks. CONCLUSION: The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI.

PURPOSE: It is known that carriage rates of Staphylococcus aureus (S. aureus) are highest in newborns and that the asymptomatic carriage of methicillin-resistant Staphylococcus aureus (MRSA) is associated with invasive MRSA infection with the colonizing strain. This study was carried out to investigate the carriage rates of MRSA in neonates with neonatal jaundice. METHODS: We reviewed the medical records of 545 neonates admitted with neonatal jaundice to neonatal intensive care units between January 2006 and December 2010. Nasal and inguinal swab specimens had been taken from them and cultured for the isolation of S. aureus. Antimicrobial susceptibility tests had been done for such isolates to determine methicillin-resistance. RESULTS: Out of 545 neonates, 318 (58.3%) were colonized with S. aureus and 214 (39.3%) were colonized with MRSA. Results of the antibiogram analysis showed that 65.7% of MRSA isolates were likely to be community-associated (CA) MRSA. CONCLUSION: Based on the MRSA carriage rate of 39.3%, a surveillance program for MRSA colonization is considered necessary in neonates transferred from other clinics or hospitals. Out of MRSA isolates, 65.7% were likely to be CA-MRSA. This suggests that CA-MRSA strains were already present in obstetric clinic environments where the neonates were born. It is thought that MRSA surveillance programs in these environments are also necessary.

OBJECTIVE: Because of the limited penetration into the central nervous system after systemic administration of numerous therapeutic compounds, intratumoral chemotherapy for brain tumors has also been used. However, the efficacy of intratumoral drug administration is restricted by the poor diffusion of drug through tumor and brain interstitium. In order to enhance the diffusion of chemotherapeutic agent and increase the cytotoxicity with minimal dose, the authors report the results of convection-enhanced delivery(CED) of chemotherapeutic agent to the malignant brain tumor as a method of enhancing cerebral drug delivery. METHODS: Authors used "CADD-Micro(R) ambulatory infusion pump" from Deltec, which can be programmed for continuous infusion. Intratumoral injection of chemotherapeutic drug using the pump was applied to eight patients with glioma and one patient with lymphoma. Surgery was done and tumor was removed as much as possible. The tip of catheter was placed in the center of tumor cavity. Adriamycin (0.16~0.32mg) was put in the reservoir which was connected to the proximal catheter and fixed in the pump device. Twenty-four hours after surgery, Adriamycin was infused. RESULTS: There was no adverse reaction of CED technique. Compared with current delivery techniques, the improvement of survival rate has been observed(5 patients: alive, 3 patients: dead, 1 patient: lost(alive to 5 mo.)). CONCLUSION: CED can be useful method for distributing therapeutic molecules in the interstitial space of tumor and can be utilized for chemotherapeutic agents, immunotoxins, and gene etc..

BACKGROUND: Definite criteria for determining severity of organophosphate poisoning have not been made. Discovery of the third neuromuscular syndrome, the intermediate syndrome, have made it more complicating then ever. Objectives of this study is to determine early prognostic factors of outcome and development of a new treatment algorithm. METHOD: 74 patients admitted to Severance hospital with acute organophosphate poisoning during 5 years were included. We made a protocol concerning the initial consciousness level, QTc interval, PVC, serum cholinesterase, the intermediate syndrome, total hospital, ICU day, length of ventilator support, disposition and have done a study retrospectively. Multiple regression and Chi-square was used as statistical analysis. Significant statistical P-value was 0.05. RESULTS: The total hospital days were prolonged as serum cholinesterase levels were lower, the age was older and mental status graver.(p<.05) The length of ventilatory support was prolonged when patient's serum cholinesterase level was very low, they were unconscious and serum cholinesterase level not recovered to 500 IU/ml within initial 3 days. The intermediate syndrome was significantly related to the prolonged cholinesterase inhibition. CONCLUSION: As an early prognostic factor for the length of ventilatory support in organophosphate poisoning, 1) level of concsiousness and 2) serum cholinesterase level at admission, 3) recovery to more than 500 IU/ml within initial 3 days are useful. Especially when the serum cholinesterase level is not recovered to more than 500 IU/ml within initial 3 days, it is essential to observe closely for the possibility of an intermediate syndrome.

BACKGROUND: Coronary stenting is one of effective and well-accepted treatments for coronary artery disease. On the other hand, side branch occlusion (SBO) is a known complication of percutaneous transluminal coronary angioplasty (PTCA) and coronary stenting. Accordingly, this study was designed to determine the incidence, predictors and acute clinical outcomes of SBO. METHODS: Coronary angiographic findings of 45 patients who had total 98 side branches originating from the stented segments were analized before and just after coronary stenting. Bifurcation lesions were divided into 3 types : type 1, type 2, type 3 and each type was subdivided into type A with significant ostial narrowing (diameter stenosis >or=50%) and type B without significant ostial narrowing of side branches. Side branch occlusion was defined as development of total occlusion or morphologic changes from type B to type A or reduction of TIMI flow more than grade 1 compared with pre-stenting flow of side branches. RESULTS: After coronary stenting, SBO occurred in 20 of 98 side branches (20.4%). SBO was significantly related with history of previous myocardial infarction (p=0.02), threatened side branch morphology (p=0.016) and poor pre-stenting flow of side branches (p=0.014). There were no serious clinical events such as myocardial infaction and death associated with acute SBO. CONCLUSION: Acute SBO can be developed in a few stented patients. Signifiant clinical and angiographic predictors of SBO just after coronary stenting were the history of previous myocardial infarction, threatened side branch morphology and poor pre-stenting flow of side branches.

OBJECTIVE: The present study aimed to evaluate the efficacy of low frequency (LF) repetitive transcranial magnetic stimulation (rTMS) over the right dorsolateral prefrontal cortex (DLPFC) for the treatment of obsessive-compulsive disorder (OCD). METHODS: Twenty-seven patients with treatment resistant OCD were randomly assigned to 3 week either active (n=14) or sham (n=13) rTMS. The active rTMS parameters consisted of 1 Hz, 20-minute trains (1,200 pulses/day) at 100% of the resting motor threshold (MT). OCD symptoms, mood, and anxiety were assessed at baseline and every week throughout the treatment period. RESULTS: A repeated-measures analysis of variance (ANOVA) was used to evaluate changes on the Yale-Brown Obsessive Compulsive Scale (YBOCS). Our results revealed a significant reduction in YBOCS scores in the active group compared with the sham group after 3 weeks. Similarly, a repeated-measures ANOVA revealed significant effect of time and time×group interaction on scores on the Hamilton Depression Rating Scale and the Clinical Global Impression-Severity scale. There were no reports of any serious adverse effects following the active and sham rTMS treatments. CONCLUSION: LF rTMS over the right DLPFC appeared to be superior to sham rTMS for relieving OCD symptoms and depression in patients with treatment-resistant OCD. Further trials with larger sample sizes should be conducted to confirm the present findings.

PURPOSE: Under the rising demand of health services, the critical pathway (CP) which standardizes the practice guideline was introduced as a means to provide quality healthcare service. CP may increase the patient's satisfaction rate by providing systematic and consistent service. We aimed to evaluate the significance of CP by development and application of CP to patients undergoing laparoscopic cholecystectomy. METHODS: From June 2010 to July 2011, 148 patients underwent elective laparoscopic cholecystectomy. Patients were divided into two groups, including 57 patients in the CP group and 91 patients in the non-CP group. In a retrospective review, related hospital costs were analyzed and compared for both groups. Survey results on satisfaction for the CP group were also analyzed. RESULTS: The mean age was 22.7 years in the CP group and 37.9 years in the non-CP group. Number of hospitalized days was one day for the CP group and 2.51 days for the Non-CP group with p<0.001. In cost analysis all variables showed a significant reduction in the CP group compared to the Non-CP group. The satisfaction rate in the CP group scored 8 points out of 10. CONCLUSION: Results have shown benefit from the financial point of the view for the CP group. Current inclusion criteria for CP are limited and still in development for a solid protocol. Further efforts with a large-scale comparative study to broaden the indication for CP are desired.

OBJECTIVE: To investigate the factors related to upper extremity functional improvement following inhibitory repetitive transcranial magnetic stimulation (rTMS) in stroke patients. METHODS: Forty-one stroke patients received low-frequency rTMS over the contralesional hemisphere according to a standard protocol, in addition to conventional physical and occupational therapy. The rTMS-treated patients were divided into two groups according to their responsiveness to rTMS measured by the self-care score of the Korean version of Modified Barthel Index (K-MBI): responded group (n=19) and non-responded group (n=22). Forty-one age-matched stroke patients who had not received rTMS served as controls. Neurological, cognitive and functional assessments were performed before rTMS and 4 weeks after rTMS treatment. RESULTS: Among the rTMS-treated patients, the responded group was significantly younger than the non-responded group (51.6±10.5 years and 65.5±13.7 years, respectively; p=0.001). Four weeks after rTMS, the National Institutes of Health Stroke Scale, the Brunnstrom recovery stage and upper extremity muscle power scores were significantly more improved in the responded group than in the control group. Besides the self-care score, the mobility score of the K-MBI was also more improved in the responded group than in the non-responded group or controls. CONCLUSION: Age is the most obvious factor determining upper extremity functional responsiveness to low-frequency rTMS in stroke patients.
