BACKGROUND: Childhood myelodysplastic syndrome(MDS) is a heterogenous disease complex which has characteristics of cytopenia in one or more hemopoietic cell lines in peripheral blood and of dysmorphisms of hemopoietic precursors in bone marrow, but quite different from adult one. We experienced 22 patients with childhood myelodysplastic syndrome during 9 years from 1987 to 1995 in the Department of Pediatrics, Inje University College of Medicine, Pusan Paik Hospital, Pusan, Korea and performed a clinical study about them to analyze the clinical and hematological features and treatment outcome retrospectively. METHOD: We analyzed their clinical features including age and sex distribution, chief complaints and physical findings on first admission, distribution of subtypes, hematologic features including initial hemoglobin, total WBC and platelet count, and treatment outcome including leukmic transformation and prognostic scores. RESULTS: 1) Of the total 22 patients, 10 were in 0-4 years of age on first admission, 8 in 5-9, and 4 above 10 years of age. The male : female sex ratio was 2.1 : 1. 2) Of the 22 patients, chief complaints on first admission were bleeding tendency in 9 patients(40.9%), pallor in 8(36.4%) and fever in 3(13.6%), in order, and physical findings on first admission were purpura or ecchymoses in 17(77.3%), anemia in 15(68.2%) and hepatosplenomegaly in 8(36.4%), in order. 3) Hematologic findings on first admission were as follows : hemoglobin levels were below 3 g/dl in 1 patient(4.5%), 3-6 g/dl in 10(45.5%), and 6-9 g/dl in 11(50.0%). Initial WBC counts were below 5,000/mm3 in 13 patients(59.1%), 5,000-10,000/mm3 in 5(22.7%) and above 10,000/mm3 in 4(18.2%). Initial platelet counts were below 20,000/mm3 in 10(45.5%), 20,000-50,000/mm3 in 5(22.7%), 50,000-100,000/mm3 in 5(22.7%) and above 100,000/mm3 in 2(9.1%). 4) Of the 22 patients, 12 patients(54.6%) were RA type, 1(4.6%) RAS, and 3(13.6%) RAEB, RAEB-T and JCML types, respectively. 5) According to prognostic scores by Mufti et al(1986), none were in 'good' group, 17 patients(89.5%) in 'intermediate' group with 39.5 months of mean duration of survival(range 4-95 months) and 2(10.5%) in 'poor' group with 18 months of mean duration of surviral(range 17-19) until the last follow-up. However, the subtypes and clinical status seemed not to be related to the prognostic scores. 6) Sixteen patients were treated with low dose cytosine arabinoside(10 mg/m2/12hrs), of whom 7 patients gained long-standing event-free survival, whose treatment regimen was changed to oral 6-TG about 2 years later. All 3 of JCML were treated with A-Triple-V regimen, one of whom was died of sepsis, one was transformed into AML and died of sepsis, while the remained one gained long-standig event-free survival (62 months). 7) Leukemic transformation into AML occured in 7 patients(RA 1, RAEB 2, RAEB-T 3, JCML 1), 6 of whom were dead, while one gained long-standing event-free survival of 34 months. CONCLUSION: We concluded that RA was the most dominant type among our patients, and the frequency to transform into AML was 31,8%, and 31.9% of the patients had long-term survival, and that reliability of prognostic scoring system by Mufti et al(1986) was not high.

PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

In order to compare the efficacies of some surgical procedures for correction of congenital muscular tortiollis, we evaluate 36 patients who had been treated either by unipolar release (19 patients) or bipolar release (17 patients) of the sternocleidomastoid (SCM) muscle at Seoul National University Children Hospital from August 1985 to June 1993. The average follow up period was 4.1 years (range, 1 year to 7 years and 8 months). The average ages at the time of operation was 3.4 years (range, 11 months to 7 years and 1 month) in the unipolar group and 9.7 years(range, 4 years and 5 months to 16 years and 11 months) in the bipolar group. Postoperatively, flexion and extension range of motion of the neck was not limited of limited less than 10 degrees, if present, in all cases. In rotation motion, 89.4% of the unipolar group and 94.1% of the bipolar group showed no limitation or limitation of less than 10 degrees when compared to the normal side postoperatively. In lateral bending, however, 21.1% of the unipolar group and 21.5% of the bipolar group showed limitation of more than 10 degrees when compared to the normal side postoperatively. Facial asymmetry, which was present in 89.4% of the unipolar group and all cases of bipolar group preoperatively, disappeared in 73.7% of the unipolar group and 23.5% of the bipolar group and improved in 94.1% of the unipolar group and 64.7% of the bipolar group. The over-all functional and cosmetic results were assessed according to the modified Ling's criteria. In function results, 14 patients(73.3%) had excellent or good results in unipolar group and 12 patients(70.6%) in bipolar group. In cosmetic results, 15 patients(78.9%) had excellent or good results in unipolar group and 11 patients(64.7%) in bipolar group. Recurrence rate was higher in the unipolar group (15.8%) than in the bipolar group (5.8%). In conclusion, limitation of lateral bending was more resistant to the treatment than the limitation of rotation. Bipolar release of SCM muscle would be recommendable even in young children in terms of recurecce.

To evaluate the degree of competitive exclusion against Salmonella gallinarum(S. gallinarum) of Salmonella enteritidis(S. enteritidis) infected chickens, fifty-six, 4-week old Hyline layer suspected of S. enteritidis infection were challenged with S. gallinarum. All chickens were tested for S. enteritidis isolation using cloacal swabs and serum plate agglutination test using S. enteritidis Ag. before challenge and classified into four groups(SE isolated, SE nonisolated, SE seropositive and SE seronegative). None of the SE isolated and the SE seropositive groups died after challenge and the average weight gains were 245.5g and 254.6g, respectively. But in the SE nonisolated and the SE seronegative groups, mortality was 18.2% and 20.6% and the average weight gains were 150.1g and 111.2g. The incidence of reisolation of S. gallinarum of the SE isolated and the SE seropositive groups were 41.7% and 47.6% from liver, 33.3% and 47.6% from spleen and 8.3% and 14.3% from cecum, respectively, and the SE nonisolated and the SE seronegative group were 63.6% and 64.7% from liver, 84.1% and 88.2% from spleen and 47.7% and 52.9% from cecum. The serological response of the SE isolated and the SE seropositive groups hardly changed from 75.0 and 81.8% before challenge to 75.0 and 85.7% after. But, the other two groups were found to be significantly higher after challenge and increased from 0 and 18.2% to 100%. Consequently, S. enteritidis preinfected chickens were found to be significant different in terms of mortality, weight gain, reisolation of S. gallinarum and serological response compared to noninfected chickens. Moreover, our study shows that S. enteritidis infected chickens appear strong competitive exclusion against the colonization of S. gallinarum.

Peripartum cardiomyopathy is defined as a syndrome of cardiac failure occurring in tbe latter part of pregnancy or in the puerperium, without obvious cause and without prior evidence of heart disease. Despite its infrequency, this clinical problem may have devastating consequences upon maternal and fetal outcome. It is important to recognize the association of cardiac failure and pregnancy as a separate syndrome so that, once identified, peripartum cardiomyopathy can be treated promptly and aggressively. We experienced two cases of peripartum cardiomyopathy, and report these cases with a brief review of the literatures.

In 1971, Harris introduced a metal backed acetabular cup to allow replacement of worn polyethylene cups and it has been popularly used now. In metal backed acetabular cup, dissociation between metal shell and polyethylene liner usually occurs with hip dislocation. We report a case of dissociation of polyethylene liner in metal bacded cup not associated with hip dislocation.
