Résumé

Medulloblastomas were originally classified under gliomas of the cerebellum until Bailey and Cushing in 1925 named these tumors as medulloblastoma. At present these tumors are classified under primitive neuroectodermal tumor. Surgical excision followed by craniospinal irradiation is the treatment of choice. A 13-year-old-girl operated for posterior fossa medulloblastoma 5 years ago presented with history of headache and vomiting on and off for 4 days in late August 2008. The MRI showed left frontal tumor which on excision was reported as medulloblastoma. Even after optimal treatment reports of recurrence abound in literature. The most common location is in the posterior fossa, followed by spinal, supratentorial, and uncommonly, systemic metastases. We conclude that medulloblastomas are highly aggressive tumor with high local recurrences if the initial excision is incomplete and that recurrence in the supratentorial area although uncommon is still a possibility. This mandates regular follow up of these children till adulthood to catch early recurrences and metastatic disease.

Résumé

Neck pain with or without radiculopathy and myelopathy is a very common problem in clinical practice. The incidence is believed to be higher in subgroups carrying load on their head. It has been reported in literature that radiographic spondylosis is appreciable in 25% to 50% of population by the age of 50 years and 75% to 85% by the age of 65 years. One hundred and nineteen lateral X-rays of cervical spine were analyzed as case-control study in patients between 40 and 50 years age with the objective of finding out proportion of cervical spondylosis in this age group and difference in the prevalence between porters and non-porters. Out of the 119 cases 54 (45.4.2%) were porters and 65 (54.6%) were non-porters. There were 98 (82.4%) males and 21 (17.6%) females. The overall prevalence of radiological cervical spondylosis was 69 (58%). The prevalence of cervical spondylosis was significantly lower (x2=14.795, p=0.0001) in porters in comparison to non-porters. The odds ratio was found to be 0.23 (0.10, 0.53) at 95% confidence interval indicating that portering significantly prohibited development of spondylosis. This study concludes that the overall prevalence of cervical spondylosis in the Nepalese population is slightly higher than in the Caucasian and contrary to other studies there is significantly lower prevalence of such degeneration among the Nepalese porters.

Résumé

Posterior fossa extradural haematoma is known for the vague signs and symptoms and a notorious course that varies from recovery to sudden death. The incidence of posterior fossa epidural hematomas among intracranial epidural hematomas has been reported from 4% to 7%. Subsequently, PFEDH with low GCS or the haematoma of more than 10 ml were subjected to evacuation. Since the volume of the posterior fossa is limited, patients deteriorate early with the development of obstructive hydrocephalus, which is visible in the CT scan in only thirty percent of cases. A retrospective study of 43 cases was done in this Institute from May 1999 to December 2005. The males (98%) have a clear predominance over female patients (2%). Road traffic accidents accounted for the majority of the cases (80%), fall for the rest (17%) and one case due to a bullhorn injury. Vomiting was the most common symptom accounting for 67% of cases followed by transient loss of consciousness in 48% and headache in 34%. On arrival to the hospital 67% presented with a GCS more than 13, 28% with score of 9-12 and the rest 5% with GCS of less than 8. Out of the total 43 cases of PFEDH surgical evacuation was done in 33(76%) and conservative management in 10 cases (23%). A dichotomised Glasgow outcome score was used to measure the outcome. This was favorable in 27 of the 33 cases operated (81%), and 7 out of the 10 conservatively managed group (70%). Overall favorable outcome was found in 34 cases (79%) with overall mortality of the study being 7%.
