The Congenital Ulnar Drift of the fingers is a relatively uncommon and has symmetrical malformations of hand, face and foot characterized by MP joint flexion contracture and ulnarward deviation of the fingers and microstomia, In tarsal deformity, there are clubfoot and congenital vertical talus with rocker bottom deformity. In treatment, the report of the surgical treatment was rare. We experienced congenital ulnar drift of fingers in 2 patients in one family, which were treated by dome resection corrective osteotomy of the metacarpals. Therefore remarkable symptomatic improvement was obtained.

Amiodarone, an antiarrhythmic drug, may exert pulmonary toxicity in some patients but the pathogenesis is not clear. This study was carried out to investigate the pathogenetic mechanism of pulmonary injury induced by amiodarone at dose of 100 mg/kg/day given to rats by intraperitoneal injection for 3 weeks. And the preventive effects of concomitantly injected steroid (10 mg/kg/day) on amiodarone induced pulmonary injury was also studied using bronchoalveolar lavage, light microscopy and transmission electron microscopy. The results obtained were summarized as follows: Mild lymphocytosis of bronchoalveolar lavage fluid was found in all experimental groups. Intracytoplasmic lamellar body formation was found in all types of pulmonary cells and type II pneumocytes revealed the earliest abnormal lamellar body formation. The capillary endothelial cells showed cellular swelling and detachment from underlying basement membrane at early phase of experiment and the edema of alveolar wall and interstitium were noted. Interstitial fibrosis and proliferation of type II pneumocytes were noted at late phase. The lungs of steroid injected groups revealed accumulation of lamellar bodies in all types of pulmonary cells but interstitial fibrosis was not occurred. These findings support the concept that amiodarone is responsible for a drug-induced phospholipidosis and directly toxic to pulmonary endothelial and epithelial cells. And steroid may regress the progression of amiodarone induced pulmonary injury.

PURPOSE: Hemolytic uremic syndrome(HUS) is the most common cause of renal failure in childhood in western countries, but it has been a relatively rare disease in Korea. To analyze the clinical and epidemiologic characteristics of HUS in Korea, we reporte our experience, METHODS: We reviewed retrospectively the medical records of 9 patients who were diagnosed the hemolytic uremic syndrorne at Pusan National University during the period from January 1984 to December 1998. RESULTS: The age at presentation ranged from 3 years to 12 years old(mean: 5.9 years). Six of the children were typical and three patients were atypical. Six cases had grossly bloody stools and seven had abdominal pain. Oliguria developed in four cases and gross hematuria in eight cases. One case had seizure and letargy. Verotoxin producing E. coli(VTEC) were found in the stool specimens of two pa- tients. One was the serotype 0157:H7 and the other was the serotype 026:H-, Olll:H21. Verotoxin 1 (VT1) genes were identified by PCR in both of the cases. All patients required conservative treatment. Two patients were treated with peritoneal dialysis, one patient with hemodialysis and one patient with plasmapheresis. Of 9 case, 6 recovered without residual sequelae, but two patients died, and one patient progressed to end stage renal failure. CONCLUSION: Two thirds of our cases were typical type of HUS, which is now the predominant type among Korean childhood HUS sufferers. From this study, we suggest that patients diagnosed with typical HUS should be studied for the verotoxin of E. coli isolated from stool.

A 25 year old patient who had low back pain and sciatica was diagnosed as having a lumbar intraspinal extradural synovial cyst adjacent to a facet joint between the third and fourth lumbar vertebrae. The extradural defects defined with positive contrast myelography and postmyelographic computed tomographic scanning were posterolateral to the dural sac. Biopsy revealed the findings compatible with synovial cyst. Treatment consisted of laminectomy and surgical excision of the cyst.

This study was aimed to investigate management conditions and dietitians' perception for improvement of school milk programs. Using an online sampling method, collected data from 1,723 dietitians nationwide were analyzed. The results show that 44.4% of respondents carried out the cyclic school milk program, providing various types of dairy products either weekly or monthly. Further, 80.3% of respondents answered that preference survey results were a determining factor in their choice of school milk provider, and 55.9% said that a school steering committee made the decision on relevant facts of the school milk program. For diversification of school milk type, 60.5% of respondents wanted to maintain the current system, and 39.5% answered that milk type needed to be diversified. The respondents preferred fermented milk products, functional milk, and processed milk, in order, if school milk type is diversified. To improve perception and knowledge about milk, 66.0% of respondents thought that nutrition education by a nutrition teacher would be the most effective, and parent's letters or a nutrition newsletter would be helpful. More than half of respondents (55.0%) disagreed with a merged program for school foodservice and milk.

An analysis for a period of 15 months (from September 2000 to November 2001), of the nutrition counseling internet site, "Dietnet" served by the Korean Society of Community Nutrition, showed the following results. Nutrition counseling was conducted without charge by 50 professionals, including professors in the food and nutritional areas, medical doctors, and dietitians. Counselees consisted of mostly females under 30 years of age. Although two thirds of the users of this site asked questions anonymously, they were very sincere. They asked questions mostly related to their own concerns, but there were quite a few inquiries about their parents or grandparents. There were significant differences in the counseling contents depending on the ages of the counselees. Teenagers showed the highest interest in height growth and weight control, whereas people in their twenties were mostly interested in diseases, foods, and weight control. Those over the thirty made inquiries mostly about diseases. The most frequent questions were relevant to gastrointestinal, circulatory and hepatic diseases. As indicated above, counseling questions included of a variety of both comprehensive and specific questions. There were also quite a few questions related to decisions on the correct usage of specific foods. Therefore, we recommend that more professionals, such as food science majors, medical doctors who practice western and oriental medicine, and other professionals who specialize in psychological behaviors related to weight control and infant food habits be recruited to serve the site more effectively and intensively. In light of the further need for internet sites with nutrition counseling and delivery of nutritional information to the public, nutritionists capable of managing websites are also required.

Staphylococcus aureus continues to be the main cause of surgical site infections. Recently, methicillin-resistant S. aureus (MRSA) has been known to be resistant to many kinds of antibiotics and causes the problem of neonatal nosocomial infection. Antibiotic sensitivity tests which have been routinely used to detect MRSA in the laboratory depend on the culture conditions. Therefore it is necessary to develop a new method based on a molecular biological technique in order to overcome these problems. We report the development of a multiplex PCR protocol for the diagnosis of staphylococcal infection. The protocol was designed to i) detect any staphylococcal species to the exclusion of other bacterial pathogens (based on primers corresponding to staphylococcal-specific regions of the 16S rRNA genes), ii) provide an indication of the likelihood that the Staphylococci present in the specimen are resistant to oxacillin (based on the amplication of the mecA gene, encoding penicillin-binding protein 2'(PBP-2'), which is known to confer resistance to the bacteriostatic action of methicillin). In this study, 67 S. aureus strains were isolated from the neonatal intensive care unit and general neonatal nursery at Pusan National University Hospital, Busan, Korea, between January and July 2003. Methicillin resistance was tested by the oxacillin disk diffusion method and the MIC method. We performed the multiplex PCR to amplify the mecA gene, encoding PBP-2'. We tested it by multiplex PCR and compared the results with the antimicrobial susceptibilities. Different results were obtained from 2 MRSA (4.65%), suggesting that the PCR method should be performed at the same time for a more accurate clinical test of MRSA

BACKGROUND/OBJECTIVES: Atopic dermatitis (AD) is a chronic disease with an increasing incidence globally; therefore, there is a growing demand for natural compounds effective in treating dermatitis. In this study, the protective effects of Lycium barbarum leaves with and without chlorophyll (LLE and LLE[Ch-]) on AD were investigated in animal models of AD and HaCaT cells. Further, we investigated whether LLE and LLE(Ch-) show any differences in physiological activity.MATERIALS/METHODS: AD was induced by 2,4-dinitrochlorobenzene (DNCB) for three weeks, while NC/Nga mice were fed LLE or LLE(Ch-) extracts for 7 weeks. Serum immunoglobulin E (IgE) and cytokine (tumor necrosis factor [TNF]-α, interleukin [IL]-6, and IL-4) concentrations and the degree of DNA fragmentation in lymphocytes were examined. A histopathological examination (haematoxylin & eosin staining and blue spots of toluidine) of the dorsal skin of mice was performed. To elucidate the mechanism of action, the expression of the thymus and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC) were measured in HaCaT cells. RESULTS: Serum IgE and cytokines (TNF-α and IL-6) levels as well as DNA fragmentation of lymphocytes were significantly decreased in AD-induced mice treated with LLE or LLE(Ch-) compared to those of the control group. The epidermal thickness of the dorsal skin and mast cell infiltration in the LLE group significantly reduced compared to that in the control group. The LLE extracts showed no cytotoxicity up to 1,000 µg/mL in HaCaT cells. LLE or LLE(Ch-)-treated group showed a reduction of TARC and MDC in TNF-α-and IFN-γ-stimulated HaCaT cells. CONCLUSIONS These results suggest that LLE potentially improves inflammation by reducing the expression of chemokines that inhibit T helper 2 cell migration. LLE(Ch-) showed similar effects to LLE on blood levels of IgE, TNF-α and IL-6 and protein expression in HaCat cells, but the ultimate effect of skin improvement was not statistically significant.Therefore, both LLE and LLE(Ch-) can be used as functional materials to alleviate AD, but LLE(Ch-) appears to require more research to improve inflammation.
