BACKGROUND: Urinary tract infections (UTIs) are the most frequent nosocomial infections and are frequently associated with indwelling urinary catheters. It is known that adherence to standard infection control measures for urinary catheters can reduce UTIs in hospitals. This study was performed to evaluate the effect of education in reducing catheter-related UTIs (CR-UTIs) in intensive care units (ICUs) of a university hospital. METHODS: CR-UTIs were prospectively monitored for all patients with indwelling urinary catheters in ICUs from July 2006 through December 2007. Recommendations based on previously known guidelines for catheter insertion, catheter management, and specimen collection to prevent CR-UTIs were formulated and educated in March 2007. Knowledge and adherence level were evaluated before and after educating healthcare workers about the recommendations using questionnaire. Changes in knowledge and adherence level before and after education were compared by Chi-square test. Changes in the rate of CR-UTIs and urinary catheter utilization ratios were also analyzed by Fisher's exact test. RESULTS: After education, knowledge level of and adherence level to most of the recommendations were improved significantly. The rate of CR-UTIs significantly decreased by 48% from 7.43/1,000 catheter-days before intervention to 3.87/1,000 catheter-days after intervention (P=0.02). CONCLUSION: Surveillance for nosocomial infections and education for standard infection control measures are very important in preventing CR-UTIs in ICUs.

PURPOSE: The aim of this study was to examine the sensitivity and specificity of the influenza rapid antigen test, in comparison with reverse transcription polymerase chain reaction (RT-PCR), according to the time of the test from symptom onset and the clinical manifestations in the patients tested for suspected infection of the influenza A (H1N1) at a second hospital. METHODS: A total of 529 pediatric patients, aged between 6 and 12 years old, who visited the emergency department from October 1, 2009 to December 31, 2009, received the influenza rapid antigen test and RT-PCR. We examined the sensitivity and specificity of the influenza rapid antigen test in comparison with RT-PCR according to the time of the test from symptom onset (<24 hours, 24 to 48 hours, 48 to 72 hours, >72 hours) and clinical manifestations (fever, cough, rhinorrhea.nasal obstruction, sore throat, gastrointestinal symptoms, and general symptoms) in a retrospective study based on hospital charts. RESULTS: The sensitivity of the influenza rapid antigen test at elapsed times of less than 24 hours, 24 to 48 hours, and 48 to 72 hours after the onset of the symptoms was 53.9%, 61.4%, and 62.1% respectively. When the elapse time was greater than 72 hours, the sensitivity was 31.6%; thus, the sensitivity of the influenza rapid antigen test tended to decrease with elapsed time. The sensitivity of the test was 79% in patients presenting with gastrointestinal symptoms, which was the highest, but there was no statistical difference according to the clinical manifestations of the patients. CONCLUSION: Our study suggests that more accurate results might be gained when the influenza rapid antigen test is performed within 72 hours after symptom onset.

Systemic lupus erythematosus (SLE) has been a well-known systemic autoimmune disease with hematologic abnormalities such as anemia, leukopenia, and thrombocytopenia. Myelodysplastic syndrome (MDS) is defined as a clonal expansion of BM derived pluripotent stem cells. Although SLE and MDS are independent disease entities, there have been several reports regarding rheumatic manifestations of MDS, which suggest that there might be a relationship between these two diseases in the pathogenetic sequence. We reviewed our cases of MDS and SLE and encountered four patients with both MDS and SLE, both of which developed concurrently. They were all women from 15 to 50 years old. They had anemia or pancytopenia. Bone marrow findings were disclosed as MDS, RA or hypoplastic MDS, RA. They had positive ANA at a titer above 1:160 of homogeneous, speckled, or dense cytoplasmic pattern. Double-stranded DNA levels increased in all cases, whereas serum complement and immunoglobulin levels were decreased except in case 1.

Purpose of this study is to evaluate the temperature lowering effects of the local cold air application on the skin surface and the muscle of different depth, and to observe whether the rebound rise of the temperature occurs after the cold air application. Subjects were prepared in a relaxed prone position. Cold air of CRAis(Kyung-won Century, Korea) was applied to the gluteal area of 20 healthy subjects for 5 minutes. The skin and intramuscular temperatures were measured by a thermogram(Infrared system, Sweden) and digital thermometers(Barnant company, USA). The temperatures were measured before and 30 seconds after the cold air application, and then every 5 minutes for the next 110 minutes. The few variables were considered that might affect the temperature changes. The thermometer-probes were inserted into the outer quadrant of the gluteal muscle below 5 cm from the iliac crest with the depth of 2 cm, 4 cm, and 6 cm respectively. ANOVA was used for the analysis of the data. The resting temperature of the skin surface was 32.6+/-1.2oC, and the lowest temperature was 12.9+/-3.3oC after 5 minutes of cold air application. The resting intramuscular temperatures with 2 cm, 4 cm, and 6 cm depth were 36.5+/-0.2oC, 36.9+/-0.2oC, and 37.1+/-0.2oC respectively (p<0.05). The lowest temperature in 2 cm, 4 cm, and 6 cm depth was 35.1+/-0.7oC, 36.2+/-0.4oC, and 36.9+/-0.3oC respectively(p<0.05). The mean duration to reach the lowest temperature was 20, 25, and 45 minutes respectively. The temperatures in the skin and the muscle with the depth of 2 cm, 4 cm, and 6 cm after 2 hours on cold air application were 32.2+/-1.1oC, 36.2+/-0.5oC, 36.6+/-0.3oC, and 36.9+/-0.3oC(p<0.05) respectively. The temperatures in the skin and the muscle were significantly lower after 2 hours than before the cold air application(p<0.05). The change of skin surface temperature was more rapid than that of the muscle and the deeper the muscle was the lesser the temperature change. In conclusion, the effect of cold air application for 5 minutes lasts up to 2 hours and the rebound rise of the temperature due to reactive vasodilatation seems not to occur in the gluteal muscle.

Seborrheic dermatitis is a chronic recurrent inflammatory disorder presumed to be caused by increased sebaceous gland secretion, metabolic changes in the cutaneous microflora, and changes in the host immune function. Stellate ganglion block (SGB) is known to increase the blood flow rate without altering the blood pressure, heart rate, or cardiac output, to stabilize hypertonic conditions of the sympathetic nerves, and to affect the endocrine and immune systems. It is used in the differential diagnosis and treatment of autonomic nervous system disorders of the head, neck, and upper limbs. The authors report the first case of successful treatment of a patient with seborrheic dermatitis through repeated SGB trials.

H-reflex is a kind of late respons which can be used for the proximal nerve conduction study. Also it is a useful and widely used nerve conduction technique es to look electrically at the monosynaptic reflex. Although recordable from all muscles theoretically, H-reflexes are most commonly recorded from the calf muscles following stimulation of the tibial nerve in the popliteal fossa. But in this study, We tried to establish the normal data and to evaluate the significance of the H-reflex study in cervical radiculopathy. H-reflexes were recorded from flexor carpi radialis (FCR) muscle, extensor carpi radialis (ECR) muscle, brachioradialis (BR) muscle, and abductor digiti minimi (ADM) muscle in 31 normal adults (62 cases) and 12 patients with cervical radiculopathy. The mean values of H-reflex latency in normal control group were 16.16+/- 1.65 msec in FCR; 15.99+/- 1.25 msec in ECR; 16.47+/- 1.59 msec in BR; 24.46+/- 1.42 msec in ADM. And the mean values of side to side difference of H-reflex latency were 0.47+/- 0.48 msec in FCR; 0.68+/- 0.72 msec in ECR; 0.63+/- 0.43 msec in BR; 22.31+/- 1.24 msec in ADM. Mean values of side to side differences of interlatency time were 0.49+/-0.47 msec in FCR; 0.73+/- 0.62 msec in ECR; 0.79+/- 0.71 msec in BR; 0.69+/- 0.44 msec in ADM. Also, there were no significant differences in H-reflex latency between right and left side. H-reflex tests in patient group with cervical radiculopathy revealed abnormal findings in 11 out of 12 patients. These results suggest that H-reflex in the upper extremity would be helpful in the diagnosis of the cervical radiculopathy.
