BACKGROUND: This study aimed to know the state of caregiver burden of family caregivers of patients with dementia and also to know factors associated with the severity of caregiver burden. METHODS: Family caregivers of dementia patients were enrolled from five general hospitals in Daegu Metropolitan city, Korea. The participants analyzed in the present study were 199 subjects who were 24 to 86 years old, living in Daegu or Kyungsang Bukdo province. Demographic features, general characteristics, characteristics of caring patients were collected and Burden Interview was done by a psychologist. Factors affecting caregiver burden were assessed using statistical analyses. RESULTS: The average severity of caregiver burden of family caregivers were between mild and moderate. Factors affecting the severity of caregiver burden were caregiving days per week among caregiver's characteristics and Neuropsychiatric Inventory and Geriatric Depression Scale among patient characteristics by multiple regression linear analysis. Caregiving cost shows marginal significance. Interestingly, cognitive scales like Mini-Mental State Examination, Clinical Dementia Rating, Physical and Instrumental Activities of Daily Living did not affect caregiver burden of family caregivers. CONCLUSIONS: This study showed that caregiving days per week of caregivers and neuropsychiatric symptoms including depressive mood of patients are closely related with caregiver burden of family caregivers of patients with dementia in Korea.

BACKGROUND: Daptomycin is a novel cyclic lipopeptide antibiotic that exhibits in vitro bactericidal activity against gram-positive pathogens including methicillin-resistant staphylococci and vancomycin-resistant enterococci. The aim of this study is to determine the in vitro activities of daptomycin against recent clinical isolates of methicillin-resistant staphylococci and vancomycin-resistant enterococci in Korea. MATERIALS AND METHODS: A total of 117 clinical strains of methicillin-resistant staphylococci and vancomycin-resistant enterococci were isolated at a tertiary-care hospital in Korea in 2004. Susceptibility to daptomycin was tested by the CLSI broth microdilution method using Mueller-Hinton broth (MHB) which was adjusted to contain a final concentration of 50 microgram/mL of ionized calcium (Ca2+). Susceptibilities to ampicillin, oxacillin, levofloxacin, vancomycin, and linezolid were tested by the CLSI agar dilution method. RESULTS: All isolates of methicillin-resistant S. aureus and coagulase-negative staphylococci were inhibited by 1 microgram/mL of daptomycin, and MIC90s were 1 microgram/mL, which were similar to those of vancomycin and linezolid. MIC90s of daptomycin for vancomycin-resistant E. faecalis and E. faecium were 0.5 microgram/mL and 2 microgram/mL, respectively, and all isolates were susceptible to daptomycin. MIC90s of linezolid and levofloxacin for vancomycin-resistant enterococci were 1-2 microgram/mL and 64 microgram/mL, respectively. Resistance rates of vancomycin-resistant E. faecalis and E. faecium to levofloxacin were 100% and 96%, respectively. Daptomycin MICs in MHB supplemented to 20-25 microgram/ml of Ca2+ were 2-8 fold higher than those in MHB supplemented to 50 microgram/mL of Ca2+. CONCLUSION: Daptomycin is very active in vitro against methicillin-resistant staphylococci and vancomycin-resistant enterococci isolated in Korea, and it is important to test in vitro activity of daptomycin using MHB containing 50 microgram/mL of Ca2+.

BACKGROUND/AIMS: The clinical significance of serum CA 125 levels in patients with chronic liver disease has not been widely appreciated in relation to the severity of the disease. We examined serum CA 125 levels in patients with chronic liver disease according to the severity of liver disease and the presence of ascites. METHODS: Fasting serum CA 125 levels were measured by a commercial RIA kit in 92 patients with chronic liver disease: 22 with chronic hepatitis and 70 with liver cirrhosis (Child class A, 19; B, 28; C, 23). Forty-one patients (45%) had ascites. RESULTS: The patients with Child class C liver cirrhosis had significantly higher mean serum CA 125 level than those with class A (p<0.05). In Child class B patients, the mean serum CA 125 level was significantly higher in patients with ascites than in those without (p<0.05). A multiple regression analysis showed that the presence of ascites, serum albumin, and prothrombin time were independent factors related to the increase of serum CA 125 levels. CONCLUSIONS: The presence of ascites is more closely related to the increase of CA125 levels in patients with liver cirrhosis than the severity of liver disease.

BACKGROUND/AIMS: The elderly patients with reflux esophagitis are less likely to feel or report their symptoms than the younger patients, even though they are more prone to complications such as bleeding, stricture or Barrett's esophagus. In this study we tried to investigate risk factors in the elderly patients who had endoscopically diagnosed reflux esophagitis. METHODS: Clinical data of six hundred and eighty seven patients with reflux esophagitis were reviewed. RESULTS: Among the 687 patients with reflux esophagitis, two hundred and thirteen (31%) were 60 or more than 60 years old. The frequency of accompanying hiatal hernia in the elderly group (age>or=60) was significantly higher than the younger group (age<60) (16.9%, 36/213 vs. 3.4%, 16/474, p<0.05). There was significant difference according age in the female group (0.9%, 1/114 vs. 22.7%, 22/97, p<0.05). The frequency of atropic gastritis was significantly higher in the elderly group than in the younger group , while other factors such as smoking, H. pylori and peptic ulcer disease were not different between the two groups. CONCLUSION: Among the risk factors of reflux esophagitis, the existence of hiatal hernia seems to be suggested more relevant to the development of this condition in the elderly group.

Some individuals may demonstrate a secondary phase nystagmus (SPN) following the caloric irrigation. It has been stated that if a SPN begins prior to 140 seconds after the onset of caloric stimulation and if the magnitude of the slow phase velocity is greater than 6 degrees/sec, then a premature reversal caloric nystagmus (PRCN) is said to exit. Thus far, there have been no reports describing PRCN in Korea. We described a typical PRCN in a patient with medulloblastoma within the 4th ventricle. The patient had a gaze-evoked horizontal and upbeating nystagmus. However, there was no indication of spontaneous nystagmus. A monothermal caloric test was administered. The initial left beating primary phase nystagmus was subsided at 60 seconds after right cold water stimulation and at 110 seconds, a right beating SPN with 14 degrees/sec of slow phase velocity was appeared and was continuous for 240 seconds. Although the precise mechanism of PRCN is unknown, vestibular nuclei damage may be related.

On rare occasions, sudden hearing loss may be associated with a migraine. To our knowledge, there have only been two prior reports of sudden hearing loss attributed to migraines. A 40 years old man had suffered from recurrent headaches with hemiparesis, vertigo, and hearing loss for the past three years. At this time, he presented with severe bilateral sensorineural hearing loss of sudden onset, anarthria, right hemiplegia, tinnitus, and vertigo. An audiogram showed a down-sloping sensorineural hearing loss of 77dB by pure tone average on the right side and 72dB on the left. Sixteen days later, audiographic findings improved to 30dB of pure tone average on both sides. Vasospasm of the labyrinthine arteries instigated by migraine might explain these inner ear symptoms. A history of migraine should be sought in patients with sudden hearing loss and when found, anti-migraine medications such as calcium channel block-ers should be considered.

BACKGROUND: For decades, patients with epilepsy and mental retardation (MR) have been considered as a relative contraindication for focal resective epilepsy surgery. However, considerable debate exists concerning whether the presence of MR is a contraindication for epilepsy surgery or not. We examined the postsurgical seizure outcome of temporal lobe epilepsy (TLE) according to preoperative intelligence scores and the relationship between preoperative intelligence and postsurgical seizure outcomes of TLE. METHODS: We investigated 131 patients with TLE divided into two groups according to standard IQ ranges and seizure outcomes were compared by Engel's classification. RESULTS: The percentage of seizure free patients after surgery was 66.4% in all patients and the percentage in patients with and without MR were 60.7% and 68%, respectively. The age at seizure onset was significantly different between the MR group and non the MR group. However, other factors which have been thought to affect the intelligence of patients with TLE were not significantly different between the two groups. The best postoperative seizure outcome was shown in the borderline group, where the frequency of hippocampal sclerosis and age at seizure onset were significantly higher compared to the other groups. CONCLUSIONS: Although preoperative MR has been regarded as a predictor for a poor prognosis of surgical outcome, our results suggest that MR alone is not a contraindication for epilepsy surgery. Therefore, epilepsy patients with MR who meet other inclusion criteria for epilepsy surgery should not be rejected for epilepsy surgery.
