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.

The aims of the Tharies replacement are to preserve bone stock and provide a more physiological and anatomical replacement using eccentic shells with the hope that long term durability will be improved. 8 cases of THARIES replacement performed between 1981 and 1983 at Hanyang UniversityHospital were reviewed and analyzed by radiography and U.C.L.A. hip rating system. Follow-up ranged from 34 to 54 months and averaged 43.3 months. The result was relatively good in 6 cases except two cases of aseptic loosening without further progression.

Intra- and extrahepatic bile duct can be invaded by hepatocellular carcinoma (HCC). This is infrequent in HCC, but it can directly affect the clinical manifestation and prognosis. We present eight cases of HCCs with emphasis on the incidence and features of bile duct invassion on computed tomography (CT). Over a period of 22 months, abdominal CT was performed in 186 with HCC patients. Out of these, five cases of bile duct invasion by HCC were confirmed in our hospital and three in other hospitals. The eight cases were evaluated for the type, size and location. CT features of intraductal mass and ductal dilatation were evaluated. The incidence of bile duct invasion in HCC was 2.6%. Infiltrative type of HCC was seen in seven cases and six of these had mass 5-11 cm in size. The characteristic CT findings of bile duct invasion in HCC are mass in common hepatic duct with bulging contour(8/80, multiple intraductal masses in the intrahepatic ducts (5/8), and diffuse dilatation of intrahepatic ducts (7/8).

Succinylcholine chloride is the most commonly used muscle relaxant. Its rapid onset of action and relatively brief duration are unique Despite its wide use, certain pharmacologic aspects of auccinylcholine chloride are not as widely appreciated as they should be. There is marked variation in the responses of patients to clinically used doses. Large doses demonstrate that recovery from succinylcholine chloride is slower than is generally appreciated in man. The dose related neuromuscular blocking effect of succinylcholine chloride in cats was investigated using a cat common peroneal nerve anterior tibial muscle preparation. All experimental cats tracheas were intubated through a tracheostomy under general anesthesia with Nembutal 40 mg/kg intravenously. Respiration was controlled by a Harvard animal respirator. The body temperature was kept at 35~37 degrees C by a thermoblanket. The degree of neuromuscular block following intravenous succinylcholine chloride, 0.5 mg/kg and 1 mg/kg, were measured by single twitch response. The common peroneal nerve was stimulated supramaximally by a single stimulus with square waves, 0. 2 msec duration and at a frequency of 0.1 Hz. The ratio of the twitch height was calculated. The results were as follows: 1) The time of neuromuscular blokade to 100% depression was 30.7 sec and to l00% spontaneous recovery was 1,260 sec (21 min.) in the succinylcholine chloride 0.5 mg/kg intravenous group. The recovery index was 258. 5 sec (4. 3 min.). 2) The time of neuromuscular blockade to 100% depression was 30 sec and to 100% spontaneous recovery was 2,004 sec (33. 4 min.) in the succinylcholine chloride I mg/kg intravenous group. No significant time difference was observed in neuromuscular depression in both groups but spontaneous recovery time was markedly prolonged to 744 sec (59% prolongation). The recovery index was also prolonged to 474 sec (83% prolongation).
