The time course of recovery in vestibular neuritis varies between individuals. The aim of this study was to identify the predictors for the early or late recovery of vestibular neuritis. The inclusion criteria were patients 1) who had an acute onset of vertigo lasting at least 24 hours, 2) with a horizontal-torsional unidirectional spontaneous nystagmus, and 3) with a canal paresis of 20% or more on the bithermal caloric tests. The primary endpoint for this study was an early or late recovery of vestibular neuritis as a dependent variable. A functional level scale was used to define the late recovery (5 or more points) at seven days after the symptom onset. The secondary endpoint was the duration of hospitalization. One hundred twenty eight patients met the inclusion criteria for this study, and among them, 71 patients had an early recovery. Multiple logistic regression analysis showed that diabetes mellitus was the only independent significant variable for the prediction of a late recovery of vestibular neuritis. In addition, the diabetes mellitus was a predicting variable for long duration of hospitalization. Diabetes mellitus was a predictor for a late recovery of vestibular neuritis.

OBJECTIVES: We aimed to examine how comorbidities were associated with outcomes (illness severity or death) among hospitalized patients with coronavirus disease 2019 (COVID-19). METHODS: Data were provided by the National Medical Center of the Korea Disease Control and Prevention Agency. These data included the clinical and epidemiological information of all patients hospitalized with COVID-19 who were discharged on or before April 30, 2020 in Korea. We conducted comorbidity network and multinomial logistic regression analyses to identify risk factors associated with COVID-19 disease severity and mortality. The outcome variable was the clinical severity score (CSS), categorized as mild (oxygen treatment not needed), severe (oxygen treatment needed), or death. RESULTS: In total, 5,771 patients were included. In the fully adjusted model, chronic kidney disease (CKD) (odds ratio [OR], 2.58; 95% confidence interval [CI], 1.19 to 5.61) and chronic obstructive pulmonary disease (COPD) (OR, 3.19; 95% CI, 1.35 to 7.52) were significantly associated with disease severity. CKD (OR, 5.35; 95% CI, 2.00 to 14.31), heart failure (HF) (OR, 3.15; 95% CI, 1.22 to 8.15), malignancy (OR, 3.38; 95% CI, 1.59 to 7.17), dementia (OR, 2.62; 95% CI, 1.45 to 4.72), and diabetes mellitus (OR, 2.26; 95% CI, 1.46 to 3.49) were associated with an increased risk of death. Asthma and hypertension showed statistically insignificant associations with an increased risk of death. CONCLUSIONS Underlying diseases contribute differently to the severity of COVID-19. To efficiently allocate limited medical resources, underlying comorbidities should be closely monitored, particularly CKD, COPD, and HF.

BACKGROUND: The aim of this study was to evaluate the sensitivity of a clinicians' self-report method for the detection of nosocomial infections (NIs) in comparison with a total surveillance method in a neonatal intensive care unit (NICU). METHODS: Two surveillance methods were concurrently performed in the NICU of a university hospital during 5 months in 2003. Clinicians' self-report surveillance (CSRS) was based on the retrospective verification of monthly reports of positive bacteriologic results by NICU clinicians. Total surveillance (TS) was done prospectively by an infection control nurse based on chart review and laboratory data. RESULTS: One hundred fifty nine patients accounting to 2759 patient-days were included in the study. Twenty-seven NIs among 26 patients were identified by TS. The sensitivity of CSRS compared to TS was 14.8% (4 of 27 NIs). The specificity was 98.5% (131 of 133 non-NIs). Kappa measures of agreement were -0.309. CONCLUSIONS: Our results confirm that the retrospective review of charts and laboratory data by clinicians lacks sensitivity and agreement for the surveillance of nosocomial infections.

Stroke is the second cause of death worldwide, although the survival period is increasing after the occurrence of stroke, severe physical disability is caused with aftereffect. Oral inflammation is not limited to the oral cavity, it can cause malignant changes in other tissues and organs. In previous studies, we confirmed the relationship between tooth loss and stroke due to periodontal inflammation. The purpose of this study was to investigate the relationship between oral health and stroke such as oral hygiene behavior, tooth loss and periodontal disease among Korean adults over 40 years of age. This study was analyzed using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. A total of 3,389 adults over 40 years of age were analyzed as final subjects. Socioeconomic statuses and oral health status was analyzed using a complex sample analysis technique. Logistic regression was used to analyze the relationship of oral health and stroke, and 95% confidence intervals were computed using SPSS. When the prevalence of stroke according to oral hygiene behavior was checked, the prevalence of strokes was lower in subjects who had a lot of brushings per day and subjects who used oral hygiene products (p < 0.05). The risk of stroke was 2.17 times (95% confidence interval, 1.43~3.28) higher in the group with less than 19 remaining teeth, but it was not statistically significant as a result of adjusting for age and sex, income level, education level, drinking and smoking (p>0.05). Loss of teeth was found to be associated with the risk factor of stroke. Therefore, loss of teeth due to periodontal disease is an additional issue that should be considered as a risk factor for stroke.

Backgound: The aim of this study was to compare the levels of perception of and compliance with handwashing between the groups of direct patient contact and indirect contact in a tertiary-care university hospital. METHODS: A cross-sectional study was conducted in a university hospital with 4,500 employees. A questionnaire, containing questions on demographic data and the perception of and compliance with handwashing, was distributed to and collected from a total of 1,087 employees from June 25 to July 10, 2005. RESULTS: The study subjects washed their hands an average of 11.2 times (range, 1-100) per day: nurses washed their hands more frequently than others. The average duration of handwashing by employees was 18.8 seconds. Those in the direct patient contact group scored significantly higher points than did those in the indirect contact group in both perception (P<.021) of and compliance (P<.001) with handwashing. CONCLUSION: Education for handwashing is needed direction employees who have indirect contact with patients to improve their compliance with handwashing.

A cerebral infarction involving the nodulus usually produce contralateral lateropulsion and ipsilateral spontaneous nystagmus to the lesion. Here, we report a case of atypical isolated nodular infarction showed ipsilateral lateropulsion and contralateral spontaneous nystagmus to the lesion with a normal head impulse test. A right-handed 70-year-old man developed sudden vertigo with an unsteady gait. Neurologic examination revealed spontaneous left-beating nystagmus with a torsional component. He also displayed imbalance of walking and axial lateropulsion to the right side. Head impulse test was normal. Magnetic resonance imaging indicated acute infarction in the right nodulus on diffusion-weighted images.

STATEMENT OF PROBLEM: The introduction of "The Long-term Care Insurance System"(a public nursing care insurance scheme) is scheduled from July in 2008. Lately, the importance of oral health care had increased. Introduction and establishment of the methodology (nursing care procedure) based on professional dental knowledge is inevitable. PURPOSE: The purpose of this study was to rouse recognition of the importance of dental care in the long term elderly care in nursing homes, with implementation of the new insurance law. MATERIAL AND METHODS: Visited two institutions for the elderly, Yudang Village and Sungjiwon located in Suwon city to investigate the present conditions in terms of (1) the detailsof the institution, (2) the activities concerning with dental care in the institution, and (3) the consciousness and recognition regarding dental care of the staffs. RESULTS: In two institutions, under the present conditions, oral cleaning (including the cleaning of denture) for residents was operated with no professional advices and limited professional dental care. It was found that there was very little awareness of aspiration pneumonia. The members of staff however, did recognizethe necessity of professional maintenance and management of oral care in daily nursing care, and that many residents hold dental problems. They were very eager in introducing the methodology (nursing care procedure) in dental care in nursing homes.

Kawasaki disease is an acute vasculitis of unknown causes that occurs predominantly in infants and young children and produces coronary artery aneurysm. We have recently experienced a case of persistent Kawasaki disease in a 24 month-old-girl improved with pulsed doses of methylprednisolone. Even with an administration of intravenous gamma globulin(IVIG), she repeated the course of recovery and aggravation. After four times repeated doses of IVIG, additional intravenous methylprednisolone pulse therapy was tried and resulted in remarkable improvement. We reported the case with a brief review of the related literature.

BACKGROUND AND PURPOSE: Sudden cardiac death is one of the leading causes of death in patients with myotonic dystrophy type 1 (DM1). It has been proposed that a prolonged QT interval is associated with sudden cardiac death in several neurological diseases, including multiple system atrophy, idiopathic Parkinson's disease, and diabetic autonomic neuropathy. However, analyses of the corrected QT (QTc) interval in DM1 patients are rare in the literature. The purposes of this study were to determine the association between the QT interval and DM1, and the affecting factors. METHODS: Thirty-nine patients diagnosed with DM1 through genetic testing were enrolled. The QTc interval (calculated using Bazett's formula: QTc=QT/radicalRR) was compared between these patients and 39 normal healthy controls. The clinical and laboratory factors affecting QTc interval in the patient group were investigated. RESULTS: The QTc interval was significantly longer in the DM1 group (411.2+/-44.7 msec, mean+/-SD) than in the normal control group (355.6+/-20.6 msec). Intragroup analysis revealed that a prolonged QTc interval in DM1 patients was associated with being female and older, having a longer disease duration, and exhibiting abnormal electrocardiography findings. CONCLUSIONS: The higher incidence of sudden cardiac death in the DM1 population is associated with the observed prolonged QTc interval in those patients.
