Risk factors of intraoperative blood transfusion in pediatric craniotomy for intracranial tumor resection: a 10-year analysis.

OBJECTIVE: A pediatric craniotomy for intracranial tumor removal brings both high bleeding and blood transfusion risks. The aim of this study was to identify the risk factors for intraoperative blood transfusion in this procedure. The secondary outcome was to investigate postoperative complications and clinical outcomes related to blood transfusion. METHODS: A retrospective analysis was performed among children who underwent a craniotomy for brain tumor resection at a tertiary hospital over a 10-year period. The pre- and intraoperative variables were examined and compared between the transfusion and nontransfusion groups. RESULTS: One hundred seventy-two patients (58%) received intraoperative blood transfusions among a total of 295 craniotomies in 284 children. Factors associated with blood transfusion were body weight ≤ 20 kg (adjusted odds ratio [AOR] 5.286, 95% confidence interval [CI] 2.892-9.661; p < 0.001), American Society of Anesthesiologists (ASA) physical status III-IV (AOR 6.860, 95% CI 1.434-32.811; p = 0.016), preoperative hemoglobin ≤ 11 g/dl (AOR 3.610, 95% CI 1.406-9.265; p = 0.008), tumor size ≥ 45 mm (AOR 2.117, 95% CI 1.214-3.693; p = 0.008), and duration of operation ≥ 6 hours (AOR 3.816, 95% CI 1.736-8.385; p = 0.001). Postoperative infection of other systems, other complications, duration of mechanical ventilation, and intensive care unit and hospital length of stay were found to be significantly higher in the transfusion group. CONCLUSIONS: Lower body weight, higher ASA physical status, preoperative anemia, large tumor size, and prolonged duration of surgery were found to be significant factors for predicting intraoperative blood transfusion in pediatric craniotomy. The identification and modification of risks from intraoperative blood transfusion can be beneficial in reducing the probability of transfusion and improving allocation efficiency of limited blood component resources.

Management of intracranial germ cell tumors at the King Chulalongkorn Memorial Hospital.

OBJECTIVE: To study the outcome of less aggressive radiotherapy combined with surgery and chemotherapy to reduce radiation complication in the treatment of intracranial germ cell tumor (ICGCT) at the King Chulalongkorn Memorial Hospital. MATERIAL AND METHOD: A descriptive study was established by reviewing patients' records from the Division of Therapeutic Radiology and Oncology admitted between 2001 and 2008. Median follow-up time was 65 months. Patient characteristics, investigations, and treatment modalities were presented in proportion. Survival analysis was evaluated by Kaplan-Meier method. The results were compared with the previous study in done in 1990 to 2000. RESULTS: Forty-two records were reviewed and 71% were male. The median age was 16 years. Pineal region was the most common site in 55%. Interestingly, 12% had synchronous lesions at both pineal and suprasellar regions. Out of 41 patients who had histopathological confirmation, 71% were germinoma. Out of 37 patients who had MRI spine or CSF cytology, 43% had CNS dissemination. Less aggressive radiotherapy combined with surgery and chemotherapy was increasingly utilized; however five-year overall survival rate in all patients was 83%, comparable to 82% from the previous study. Survival rates of patients without CNS dissemination were 88% in the present study and 83% in the previous study. Survival rates adjusted for histopathology were 86% for germinoma and 76% for non-germinoma. CONCLUSION: Less aggressive radiotherapy combined with surgery and chemotherapy to reduce radiation complication is an effective treatment for ICGCT.

Currarino syndrome: report of two cases and review of the literature.

In the present paper the authors examine two cases of Currarino syndrome and review the existing literature on the disease. Both cases presented with chronic constipation. The first concerns a two year old male born with anorectal stenosis and diagnosed with Currarino syndrome when scimitar sacrum and anterior meningocele were finally detected. The second concerns a 25 year old female who suffered from chronic constipation but was not diagnosed until thorough examination revealed ectopic anus with Hirschsprung disease, scimitar sacrum and anterior meningocele. Because these patients were not diagnosed with Currarino syndrome when first seen, the authors reviewed its prevalence, embryogenesis, clinical manifestations, diagnosis and treatment. The authors' research supports the significance of prompt diagnosis in effective treatment and reduction of morbidity.
