Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

A preliminary study was conducted to evaluate the immediate postoperative recovery and socioeconomic efficacy with the surgical release of Carpal tunnel syndrome by double incision technique. Sixty cases of carpal tunnel syndrome were operated by one surgeon between 1993 and 1995 and 44 cases in 39 patients were available for this study. Surgery was done under axillary block and patients were evaiuated preoperatively, 3 weeks and 6 weeks each postoperatively. The evaluation was focused on the immediate recovery in terms of subjective symptoms of pain and paresthesia, local tenderness, strength of grip power and pinch power and postoperative disability. 1l was noted that surgical release of carpal tunnel syndrome utilizing double incision technique was as effective as seen in the endoscopic release in terms of quicker recovery of pain, local tenderness and strength. It was also noted that this double incision technique was as safe and economically beneficial as observed in the conventional open procedure.

This study aims to determine the changes in health beliefs and practices of dental hygienists on infection control after having received special training on that subject. The study population consisted of dental hygienists working at the dental institutions located in Seoul and Gyeonggi areas. The intervention group and the control group each had randomly assigned 26 dental hygienists. The intervention group received training courses on infection control once a week for 3 hours, for a total of 4 training sessions. We used a survey tool to find the changes between the two groups regarding their health beliefs and practices on infection control measures. The survey was conducted prior to the training sessions, 3 months and 2 weeks after the training. The study results revealed statistically significant increases in perceived sensitivity, perceived seriousness, and perceived benefits after the training courses in the intervention group (p<0.05). A statistically significant decrease in perceived barriers was also noted in the intervention group (p<0.05). Additionally, there was a statistically significant increase in the practice of infection control in the intervention group as compared to the control group (p<0.05). Therefore, we conclude that infection control training is crucial in bringing about positive changes to the health beliefs of dental hygienists, and a structured system is necessary for continuous infection management along with training in order to improve infection control practices.

Background: The diagnosis of acute leukemia is multidisciplinary with histology, immunology, and cytogenetics. Among these, cytogenetics is important for diagnosis and analysis of prognosis and some of the chromosomal abnormalities are specific for the particular subtypes of acute leukemia. However, cytogenetic analysis is laborious and sometimes does not provide sufficient metaphases. To detect the common 7 gene rearrangements in acute leukemia, a reverse transcription-polymerase chain reaction (RT-PCR) was performed simultaneously under the same conditions. Methods: The author analyzed 38 cases of acute myeloid leukemia (AML) and 20 cases of acute lymphocytic leukemia (ALL) for the evaluation and treatment of acute leukemia. The simultaneous RT-PCR assays were performed under the same conditions to detect 7 chromosomal abnormalities of t(1:19), t(8; 21), t(9; 22), dupMLL (11q23), t(12; 21), t(15; 17), and inv(16) in acute leukemia. Results: The simultaneous RT-PCR assay detected the expression of 7 fusion genes generated by chromosomal rearrangement. The gene rearrangements were found in 53% of AML and 40% of ALL. In AML, there were 7 cases of PML/RARA, 6 cases of AML1/ETO, 4 cases of dupMLL, and 3 cases of CBF/MYH11. In ALL, 4 cases of dupMLL, 2 cases of BCR/ABL, 1 case of E2A/PBX1, and 1 case of TEL/AML1 were detected. The discrepant results between simultaneous RT-PCR and cytogenetic analysis were found in 11 cases. Nine cases were positive by simultaneous RT-PCR but negative in the cytogenetic analysis and each case of variant t(9; 22) and t(15; 17) was negative in simultaneous RT-PCR. Conclusions: It suggests that the simultaneous RT-PCR assay is an efficient and fast procedure for the detection of genetic changes in acute leukemia and it appears to be an useful method for rapid diagnosis of acute leukemia.

Prenatal chromosome analysis of amniotic cells at 18 weeks of gestation showed a male fetus to carry a large 15p+ derivative chromosome inherited from his mother. Extra genetic material on the short arm of chromosome IS was silver-negative with Ag-NOR (nucleolus organizer regions) stain, but stained darkly with C-banding method like the distal heterochromatic segment of the Y long arm. Fluorescence in situ hybridization (FISH) using two DNA probes (DYZ1 and D15Zl) showed a red fluorescent signal on 15p+ In addition to a green chromosome 15 centromere signal, confirming 15p to be from the distal Yq heterochromatin.

The deletion 9p syndrome is a well characterized syndrome with about one hundred cases having been reported. Most patients have dysmorphic facial features, cardiac anomalies, and mental retardation. We report on a female infant with micrognathia, corneal opacity, cleft palace, cardiac anomaly, left polycystic kidney, and deletion 9p. Chromosome analysis and fluorescence in situ hybridization (FISH) showed her to have a derived chromosome 9 inherited from a maternal t(9;16) (p22;p13.2) by adjacent I segregation There are few reports of this particular chromosome rearrangement. We review deletion Sp syndrome.

BACKGROUND: Methicillin-resistant Staphylococcus aureus(MRSA) is an increasingly common cause of nosocomial infections worldwide. Epidemiologic investigation of MRSA outbreaks and identification of pathways of nosocomial MRSA spread require the ability to distinguish individual MRSA strains. We applied molecular tap ing of the methicillin-resistant determinant (mec) and coagulase typing in the investigation of a nosocomial MRSA infections. METHODS: We randomly selected 79 strains of mecA positive MRSA isolated from patients who visited Dong-A university Hospital from Dec. 1995 to Oct. 1996. Molecular typing of MRSA was performed by comparing the size of the mac-associated hypervariable region amplified by the polymerase chain reaction (PCR). Coagulase typing with type I-VIII antisera was also used for classification of MRSA based on its phenotype. Each isolates were classified by the combination of molecular analyses and coagulase type. RESULTS: The 79 MRSA isolates were grouped Into sin hypervariable legion (HVR) genotypes on the basis of the size of the PGR products. In coagulase typing, the most predominant type was II(46.8%) and type V was not found. Nine strains were not typable. The combination of HVR genotypes and coagulase types showed 23 different types in 79 MRSA Isolates. The strains which were repeatedly isolated from the same patients showed the same HYR genotypes and coagulate types. CONCLUSION: The combination of HVR genotypes and coagulase types is thought to be useful in epidemiolgical Investigation of nosocomial infections caused by MRSA ,because of its simplicity and reproducibility.

BACKGROUND: Recent DNA polymorphism analysis using numerous DNA markers has been used to determine the parental origin of the extra chromosome 21 in Down syndrome. In this study we used seven dinucleotide repeat polymorphisms on chromosome 21 to characterize a case of rea(21q21q) and to know whether it is consistent with an isochromosome or a true Robertsonian translocation. METHODS: Cytogenetic investigation was done by conventional G banding DNA was extracted from whole blood of a proband and her parents and was amplified by PCR using seven sets of (GT)n repeat dinucleotide markers located on the long arm of chromosome 21 After electrophoresis of the PCR product in polyacrylamide gel and silver staining the parental origin and number of DNA copy were determined by visual comparison of the band intensities within and between individuals. RESULTS: Conventional cytogenetics showed that the proband had a 46.XX.re(21q21q) chromosome pattern. Parental chromosome studies were normal, therefore, the rearrangement was a de novo event. All seven DNA markers showed one or two alleles, demonstrating rea(21q21q) to be an isochromosome. For D21S215 and D21S156 markers both parents were heterozygous and the proband inherited one copy of paternal allele and two copies of maternal allele which both parents did not share. This finding was consistent with a maternally derided isochromosome. CONCLUSION: Use of dinucleotide repeat DNA polymorphisms after PCR amplification will be very useful to detect the parental origin of additional chromosome 21 or rearrangement of chromosome 21 in Down syndrome. Besides employing siltier staining of a PCR product we will be able to avoid using of radioisotopes and apply to clinical laboratory diagnosis.

PURPOSE: This study was done to analyze the relationship between organizational communication satisfaction and organizational commitment among hospital nurses. METHOD: A survey was conducted with 647 nurses who were working in 24 hospitals in Korea. Data were collected during August 2010. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation analysis, and multiple regression. RESULTS: The mean level of organizational communication satisfaction was 3.15 (min 1.88 -max 4.88) and the mean level of organizational commitment was 3.21 (min 1.33 - max 4.83). There was a statistically significant correlation between organizational communication satisfaction and organizational commitment (r=. 655). According to analysis of the impact of the subconstructions of organizational communication satisfaction on organizational commitment, the following factors had significant influence on organizational communication satisfaction: vertical communication, communication media, and organizational climate. CONCLUSION: These findings showed that communication satisfaction was the most important factor for nurses' organizational commitment. Therefore, there is a need to develop communication strategies and skills for hospital nurses to increase the level of communication satisfaction.
