Complicated hepatic microabscess secondary to ascending cholangitis following ERCP (Endoscopic retrograde cholangiopancreatogram) is rare, and needs to be differentiated from other microabscesses, metastasis or Caroli's disease. We experienced a case of hepatic microabscess associated with septic cholangitis following ERCP. Cholangiogram showed multiple sac-like abscess pockets with characteristic biliary communication, and CT scan revealed multiple low attenuated lesions. At the resolving stage of chotangitic microabscess, CT scan showed partial rim enhancement of the abscesses and disproportional dilatation of intrahepatic ducts. The residual parenchymal enhancement surrounding the resolved microabscess pockets and dilatated biliary ducts, however, remained even after clinical recovery.

BACKGROUND: Peripheral blood stem cell transplantation in children has some difficulties compared with adult cases. Despite the children's total blood volume is small, they have a relatively higher volume of blood per weight than adults. Also, it is hard for the children to maintain 2 central vein during leukapheresis to shorten the time consumed. We compared the artery-harvest and central vein-harvested group for possible risk and stem cell yield in pediatric patients with malignancies. METHODS: From August, 1995 to January, 1997, 21 leukapheresis was performed by 7 patients. The patients who could have 2 central veins for leukapheresis were included in vein-harvested group and the patients who could have only 1 central vein were included in artery-harvested group. The peripheral vein was not used for leukapheresis. COBE Spectra(COBEBCT, Lakewood, CO) was used and priming was done by packed RBCs in patients weighing less than 20kg. Stem cell yield was assessed by MNC, CD34+, CFU-GM, respectively. During leukapheresis, the patients were closely monitored for change in vital sign, evidence for thrombosis, bleeding, hypocalcemia, etc. RESULTS: There was no serious complication in each group of patients. After the leukapheresis, WBC and platelet count decreased but Hb level was increased due to reinfusion of primed packed RBCs. Average flow rate was higher in vein-harvested group but there was no difference in time consumed and results in stem cell assay. CONCLUSION: Peripheral stem cell harvest in children by radial artery can be performed safely and easily without an increased risk or complication. In younger children, it is possible to achieve even more higher stem cell yield. If the patient is unable to maintain 2 central vein for leukapheresis, transient radial arterial catheterization is a safe and convenient method.

Urea reduction ratio (URR) and Kt/Vurea are objective parameters of dialysis delivery in hemodialysis patients and correlate with nutritional status and patient outcome. URR and Kt/Vurea depend on postdialysis blood urea nitrogen (BUN). In patients with severe postdialysis urea rebound (PDUR), these parameters do not accurately reflect dialysis adequacy. We measured PDUR 30 minutes after dialysis in 26 chronic stable hemodialysis patients. The impact of PDUR on dialysis delivery assessed by URR and Kt/Vurea and the independent factors affecting on PDUR were evaluated. All patients had been dialyzed for 4 hours thrice a week using hemophan membrane. 1) The mean age of patients was 48.6+/-14.8 years and sex ratio was 1:2.3. The mean duration of hemodialysis was 42.7+/-45.0 months. Primary renal diseases were chronic glomerulonephritis 11 (42.3%), diabetic nephropathy 7 (26.9%), and hypertension 4 (15.4%). 2) The mean blood flow was 209.2+/-17.4ml/min. URR, Kt/Vurea, and nPCR using immediate postdialysis BUN were 60+/-7%, 1.13+/-0.21, 1.09+/-0.28g/kg/ day, respectively. The mean recirculation rate was 4.4+/-2.3%. 3)The mean PDUR was 12.2+/-4.6% (range:6-22 %). URR, Kt/Vurea, and nPCR using BUN 30 minutes after dialysis were 55+/-7%, 0.99+/-0.18, and 1.02+/-0.25 g/kg/day, respectively and were significantly lower than those using immediate postdialysis BUN (P<0.05). 4) When the patients were divided according to the degree of PDUR (low PDUR group:<12%, high PDUR group: > or = 12%), high PDUR group was significantly higher than low PDUR group in hematocrit (27.0+/-2.6 vs. 23.5+/-3.6%, P=0.008), URR (64.3+/-5.4 vs. 55.8+/-6.8%, P=0.002), Kt/Vurea (1.26+/-0.17 vs. 1.03+/-0.18, P=0.002), and total recirculation rate (5.6+/-2.7 vs. 3.6+/-1.7%, P=0.05). There were no differences in age, sex, postdialysis body weight, ultrafiltration rate, blood flow, serum albumin, predialysis BUN, creatinine, and nPCR. 5) In multiple regression analysis, the independent factors affecting on PDUR were Kt/Vurea (beta=0.546, P<0.001), recirculation rate (beta=0.422, P<0.001), and hematocrit (beta=0.366, P=0.0017). In conclusion, we think that PDUR should be considered in hemodialysis patients when estimating dialysis delivery, especially if they had high Kt/ Vurea, recirculation rate, and hematocrit.

Delayed emergence of speech or language are frequent causes for concern about development during early childhood. Delay in evaluation and proper management until school entry in more likely to result in frustration, anxiety and school failure. Many language disturbances and their attendant behavior disorders respond to intensive language therapy. Authors analyzed the medical records of 52 children with delayed language development evaluated during 30 months from January 1986 through June 1988. The results were as follows: 1. The majority of cases were evaluated at the age of 2-2.9 year old (16 cases, 30.8%) and 3-3.9 year old (11 cases, 21.2%) 2. Male to female ratio was 3:1 3. The most common cause was mental retardation (53.8%), followed by developmental language disorder (23.1%) and autism (13.5%) 4. The most common associated condition was dysarticulation (17.3%), followed by strabismus (9.6%) and seizures (7.7%) 5. Special education was recommended in cases of 23 (44.2%), speech therapy in 12 cases (23.1%) and consultation to child psychiatry in 7 cases (13.5%) Making diagnosis of underlying disorders in not simple because assessment of intelligence in young children in difficult and only a few tests are standardized. More detailed study on children with delayed language development and development of psychometric tests for handicapped children are necessary, especially in Korea.
