Use of intravenous immunoglobulin in a disseminated varicella infection in an immunocompromised child / 소아과

Varicella-zoster virus infection can lead to severe illness in immunocompromised patients. Further the mortality rate of disseminated varicella infection is extremely high particularly in immunocompromised children. We report a case of disseminated varicella infection in a child with acute lymphoblastic leukemia who was receiving chemotherapy, but was initially admitted with only for acute abdominal pain. The patient rapidly developed severe complications, including acute respiratory distress syndrome, acute hepatitis, disseminated intravascular coagulation, and encephalopathy. Acyclovir is a highly potent inhibitor of varicella-zoster virus infection. However, owing to rapid disease progression, it might not be sufficient to control a disseminated varicella infection, especially in immunocompromised patients. Immunoglobulin neutralize virus invasion and suppress viremia, acting synergistically with acyclovir. In this case, early administration of acyclovir and a high-dose of immunoglobulin, combined with mechanical respiratory support, proved adequate for treatment of this severe illness.

Incidence and Risk Factors for Early-Onset Hypertension after Allogeneic Hematopoietic Stem Cell Transplantation in Children

BACKGROUND AND OBJECTIVES: Survivors of pediatric hematopoietic stem cell transplantation (HSCT) are at risk for developing hypertension. The objectives of this study are to evaluate the prevalence and risk factors of early onset hypertension during the engraftment period after HSCT. SUBJECTS AND METHODS: This is a retrospective study of 157 consecutive patients (mean age at HSCT: 9.1+/-5.1 years) who underwent HSCT for acute myeloid leukemia (n=47), acute lymphoblastic leukemia (n=43), severe aplastic anemia (n=41), and other reasons (n=26). Blood pressure data were collected at five time points: 0, 7, 14, 21, and 28 days after HSCT. Hypertension was defined as having systolic and/or diastolic blood pressure > or =95th percentile according to age, gender, and height. To analyze the risk factors related to hypertension, data, including patients' demographic and transplant characteristics, were reviewed. RESULTS: Hypertension developed in 59 patients (38%), among whom 12 (7.6%) required long term therapy. Thirty-two (54%) patients had systolic and diastolic, 8 (14%) had only systolic, and 19 (32%) had only diastolic hypertension. Younger age, acute graft-versus-host disease, sinusoidal obstruction syndrome, treatment with antifungal agent, and greater increase in serum creatinine (Cr) levels were associated with hypertension. Multivariate analysis showed that younger age at HSCT and greater increase in serum Cr level were independent risk factors for hypertension. CONCLUSION: Prevalence of hypertension during immediate post-HSCT period is high, especially in younger children. A greater increase in Cr after HSCT was significantly associated with hypertension. Further study is needed to elucidate long-term cardiovascular complications in pediatric HSCT survivors.

Analysis for Spontaneous Remission of Chronic Immune Thrombocytopenic Purpura in Children / 임상소아혈액종양

BACKGROUND: Chronic immune thrombocytopenic purpura (chronic ITP) is the most common autoimmune disease for blood elements. Some patients recovered spontaneously during follow up of disease. We investigated the difference of related clinical parameters between spontaneous remission and no remission. METHODS: We reviewed retrospectively medical records from January 1994 to December 2010. We analyzed clinical parameters such as age, sex, initial platelet count, response to initial treatment, maintenance therapy, and platelet counts at post-diagnosis with regular period in children with or without spontaneous remission. RESULTS: This study was enrolled for 49 children with chronic ITP. Median age was 3.5 years (0.1-17.3). Male to female ratio was 1:1.9. Initial treatment with intravenous immunoglobulin was received in 36 children (73.3%). Spontaneous remission was shown in 23 children (46.9%) during study period with 4.4 year of median follow up. The relevant factors of remission were observed in younger age at diagnosis, maintenance therapy, and platelet counts at post-diagnosis 1 year, 2 years, 3 years (P<0.05). The most significant parameter for spontaneous remission was platelet count at post-diagnosis 6 months in Kaplan-Meier estimate (P=0.047, RR: 3.47, 95% CI: 1.03-24.04). CONCLUSION: Spontaneous remission was shown in about half of patients with chronic ITP. This remission was related with younger age, maintenance therapy, and platelet count at post-diagnosis 6 months. These results suggest that regular follow up with maintenance therapy may be required for management of chronic ITP in children.

Surgical Management of the Tumor in the Parapharyngeal Space and Infratemporal Fossa Using Zygomatic arch and Mandibylar Osteotomy

A new surgical approach to the area of the infratemporal fossa and parapharyngeal space is described. This approach results in a wide-field exposure of the infratemporal fossa, pterygomaxillary space and parapharyngeal space. We used two osteotomies on the patient's mandible and temporary resection of zygomatic arch for superior margin of tumor. Lower lip splitting was not needed because the incision was started in the frontal scalp, curved in front of and below the external auditary canal, and extended anteriorly to the greater horn of hyoid bone on the neck along a skin crease. We had good results without sacrifice of the facial nerve, mandibular function and sensory supply of the face and oral cavity.
