Diagnosis of medulloblastoma in pregnant women: To continue with the pregnancy or not? A case report and literature review.

BACKGROUND: Medulloblastoma (MB) is an uncommon and challenging diagnosis in pregnant women, and especially in pregnancy after in-vitro fertilization (IVF). Clinical features are easily misinterpreted and mistaken for other more common gestation-related pathologies. We report the case of a 34-year-old patient with clinical symptoms of intracranial hypertension. MB was diagnosed and operated on during the pregnancy. OBJECTIVE: To conduct a systematic literature review of other cases of MB operated on during pregnancy, and discuss the clinical and surgical management of MB in pregnancy. METHOD: We conducted a systematic literature review according to PRISMA guidelines. RESULTS: In addition to the present case, 9 cases of MB were reported as operated on during viable pregnancy. In one case, medical abortion was decided on before surgical debulking. Pregnancy term was between 8 and 30 weeks. The most common symptoms were headache, nausea and vomiting followed by dizziness. Tumor prognosis after treatment was favorable in 6 cases out of 10 and unfavorable in 4, with 3 cases of recurrence and 3 of death. CONCLUSION: We report the first case of long-term survival after MB in a woman pregnant via IVF. In standard-risk MB, it is possible to carry the pregnancy to term. Vaginal delivery is not contraindicated a priori. Early diagnosis, close clinical and radiological surveillance and surgery are the key factors for better prognosis. Multidisciplinary collaboration is crucial to determine the best timing and treatment.

Which centers should be authorized to treat craniosynostosis? A plea for quality and not for quantity.

BACKGROUND: In centers for craniosynostosis surgery, the volume of activity does not necessarily reflect the quality of the treatment. OBJECTIVE: Our aim was to analyze a retrospective series of patients over a period of 6 years in a low-volume craniosynostosis surgery center, and to study indicators that reflect the quality of treatment. PATIENTS AND METHODS: The analysis included all patients who underwent a craniofacial surgery for all forms of craniosynostosis during the period 2012-2017 (annual follow-up for 4 years). Data on the type of synostosis, sex, age, weight, type of surgery, duration of surgery, blood transfusion, postinterventional care, and total length of hospital stay were collected. Medical and surgical complications were recorded using the Leeds classification. RESULTS: Overall, 42 patients (33 male; 23 cases of scaphocephaly, 13 cases of trigonocephaly, 4 cases of coronal plagiocephaly, 1 case of lambdoid plagiocephaly, and 1 case of brachycephaly) underwent craniofacial surgery with a median age of 7.4 months [4.8; 10.4] and a mean weight of 8.40 ± 1.92 kg at surgery. The median hospital stay was 7 days [6;7] with 1 day in the postinterventional care unit for 83% of patients. The global complication rate was 12% (95% CI: 4%-26%) with three minor cutaneous and two major (cardiovascular and septic) complications. CONCLUSION: Complication rates reflect the quality of care in a center that treats craniosynostosis much more than do the number of procedures, mean hospital stay, and blood transfusion rates. It is essential to define new indicators capable of measuring the quality of life linked to surgical procedures and of using them to assess the competence of a center.

Postoperative empyema following chronic subdural hematoma surgery: Clinically based medicine.

INTRODUCTION: Subdural empyema (SDE) is a rare complication of chronic subdural hematoma (CSDH) surgery. We introduced antibiotic prophylaxis (AP) for this procedure in 2014 following a morbidity-mortality conference (MMC) in our department. We report the results of retrospective data analysis to assess the effect of systematic AP and to identify risk factors for SDE. MATERIAL AND METHODS: Two hundred eight patients were recruited between January 2013 and December 2015; 5 were excluded for incomplete data: 107 without and 96 with AP (n=203). SDE was confirmed by clinical examination, imaging and bacteriological analysis. Comparisons between AP-(no cefuroxime) and AP+ (cefuroxime) groups were made with Chi2 test and Student's t-test. RESULTS: One empyema was found in each group, indicating that AP had no effect (P=1). The only criterion associated with SDE for these two patients was a greater number of reoperations for CSDH recurrence (P=0.013). DISCUSSION: The incidence of postoperative empyema was 1%, similar to the range of 0.2%-2.1% reported in the literature. This rare incidence explains why we found no significant effect of AP. The medical decision taken at the MMC did not help to reduce the rate of postoperative SDE. MMCs can help to define factors associated with adverse surgical events and identify opportunities for improvement. CONCLUSION: AP, introduced after an MMC, did not impact SDE rates. In practice, AP should be required only in case of reoperation for CSDH recurrence. However, we still continue to use AP following the MMC considering different parameters discussed in the manuscript.
