1.A Case of Saethre - Chotzen Syndrome.
Journal of the Korean Society of Neonatology 1998;5(1):117-120
Anti-HLA antibody related neonatal thrombocytopenia is an uncommon disorder caused by platelet antigen incompatibility between mother and fetus in Korea. Mothers who lack the specific platelet antigen produce the IgG against the platelet antigen which the fetus inherits from the father. These IgG antibodies are then transported across the placenta into the fetal circulation where they lead to the destruction of fetal platelets. We report a case of neonatal alloimmune thrombocytopenia related with anti-HLA antibody in second baby of dizygotic twin who had petechia on trunk and platelet count 43,000/mm. Initially, mother and twin showed the positives in antiplatelet antibodies. In microlym- phocytotoxic test at 6 months of age, anti-HLA antibodies was negative in twins but anti-HLA A2, A24 was positive in their mother. The patient was treated with intravenous immunoglobulin and clinically improved and her platelet count was norrnalized.

The morphologic abnormalities of the endocrine pancreas that underlie persistent neonatal hyperinsulinemic hypoglycemia and are included under the heading "nesidioblastosis" appears to be heterogeneous. This characteristic morphologic finding is ductuloinsular complexes showing endocrine cells budding off the ductoepithelium and merging with adjacent endocrine cell clusters. A case of nesidioblastosis associated with hyperinsulinemic hypoglycemia occurred in a 6/365 year-old male neonate. Microscopic finding of near totally resected pancreas revealed irregular sized islets and ductuloinsular complexes, both of which contained hypertrophied B cells with a few mitosis. Because of persistent hypoglycemia after first operation, he received second operation 8 days after. This histologic finding was more severe comparative to that of first operation. According to these findings, the pathogenesis of nesidioblastosis may be congenital or developmental defect of a kind of compensatory mechanism by unknown stimuli to acquire persistent hypoglycemia.

Partial trisomy 10q syndrome is a rare chromosome anomaly characterized by severe mental and growth retardation, craniofacial dysmorphia with prominent forehead, fine arched eyebrows, deep set small eyes and micrognathia, In addition, other physical manifestations have been reported as skeletal anomaly, congenital heart disease, inguinal hernia, and so on. We report a case of partial trisomy 10q syndrorne with certain stigmata which confirmed by chromosome analysis.

Many modalities of the treatment of fractures of distal 1/3 of tibia were introduced. But, May anatomical bone plate is considered to be a valuable method in treating distal 1/3 tibial fractures because of reduction potentiality by their contour, ability of firm fixation, decreased complications. Twenty two patients having distal 1/3 tibial fractures, were treated by May anatomical bone plate, at the Department of Orthopedic Surgery, Inchon Chirstian Hospital from January 1988 to December 1993. The results were follows; 1. Ninteen cases(86%) out of 22 were closed fractures and the remaining 3 cases(14%) were open fracrues, the comminuted fractures were 6 cases(22%) and the segmental fractures were 2 cases(9%). 2. Average interval from injuy to operation was 16.8 days and 21 cases had associated injuries. 3. The mean duration of bone union was 16.9 weeks. 4. Seven cases(31.8%) of delayed union and two cases(9.1%) of superficial infection were noted.

Lead is one of the most widespread environmental toxins and its poisoning in children was considered a rarity, usually resulting from unique circumstances such as inappropriate use of leadbased body cosmetics or direct administration of lead-containing folk medicines. The increasing concern about children with lower levels of lead exposure has developed, but there are no data regarding the mean blood lead levels and the incidence of symptomatic or asymptomatic lead poisoning in Korean children. We analyzed the zinc protoporphyrine (ZPP) values and blood lead concentrations in 163 pediatric inpatients for a prospective study of lead exposure. The blood lead concentrations in all 163 children were 15~54 g/dl, of whom 111 children (68.1%) were 25~54 g/dl which needs decision to chelate based on the EDTA provocation test. Among 111 children whose blood lead concentrations are 25~54 g/dl, 59 children(53.2%) were between 7 months and 3 years of age, which revealed no significant higher incidence of lead exposure than any other age group. The ZPP values in 126 children (77.3%) were above 35 g/dl. The mean blood lead concentration and ZPP values are 27.8 g/dl and 48.8 g/dl, respectively. We conclude that there are many asymptomatic children with increased absorption of lead in the urban area of Korea, and we need further studies regarding lead poisoning. It is important that there must be a national counterplan and that pediatricians continue to pay attention to lead posioning in children.

Renal papillary necrosis is rare. It usually occurs in association with diabetes mellitus, pyelonephritis, urinary tract obstruction, analgesic abuse and sickle cell hemoglobinopathies. The basic pathophysiologic process in renal papillary necrosis appears to be ischemic necrosis. We experienced a case of renal papillary necrosis associated with diabetes mellitus. This 59 years old female was diabetic for 10 years and had persistent pyuria, not controlled with antibiotics. The excretory urography showed nonvisualized left kidney and retrograde pyelography showed multiple irregular filling defect in pelvis and ureter. The nephrectomized kidney showed typical findings of papillary necrosis, grossly and microscopically.

PURPOSE: Both antithrombin III(ATIII) and Gabexate mesilate(Foy) are effective for the treatment of disseminated intravascular coagulation(DIC). However, their mechanisms of action are slightly different, and combined effect of ATIII and Foy in premature infant with DIC has not been studied. We evaluated therapeutic efficacy of treatments with either ATIII or Foy alone or both in combination. METHODS: We studied 23 premature infants of gestational ages between 30 and 36 weeks with DIC. Group A(n=10) was treated by ATIII only, Group B(n=7) by Foy only and Group C(n=6) by both ATIII and Foy. Three groups were compared for volume of blood sampling and transfusion and hematologic data. RESULTS: Improvement of hematologic data(platelet, PT, aPTT, fibrinogen, FDP) was not significantly different among 3 groups. The mean volume of blood sampling during 5 days of treatment was 30 mL, 22.5 mL, and 30 mL, respectively. The mean volume of packed RBC transfusion was 12.8 mL, 9 mL, and 2.5 mL, respectively: and mean volume of platelet transfusion was 25.9 mL, 10 mL, and 0 mL, respectively, showing no significant statistical difference. But the mean volume of FFP transfusion was 141 mL only in group B, significantly higher compared to other groups. CONCLUSION: The combination therapy of ATIII and Foy significantly decreased the volume of FFP transfusion and may be more effective than monotherapy with ATIII or Foy alone in DIC of premature infant.

Leiomyoma is commonly found in the female genital tract, but occurrence in the urinary bladder is very rare with only 235 cases reported in the literature. These tumors have been classified as intravesical (63%), intramural (7%) and extravesical (30%) depending on the direction of the growth. We report a case of intravesical leiomyoma of the urinary bladder in a 36 year-old woman who exhibited dysuria and urinary retention. The gross and microscopical findings of leiomyoma of the bladder are similar to those of the uterus. Immunohistochemical stains for estrogen receptor (ER) and progesterone receptor (PR) revealed diffuse nuclear staining in smooth muscle cells, supporting the hypothesis of hormonal influence in tumorigenesis.
