Background: Brain tumour is a common problem in paediatric age group and posterior fossa is the commonest location. Treatment of these tumours is difficult due to a confined space and potential involvement of brainstem. The aim of this study is to analyse the clinical features, radiological findings, pathological diagnosis, surgical management, postoperative complications and outcome in 3 months in paediatric patients with posterior fossa tumours. Method: Retrospective chart review of 24 patients treated in the Department of Neurosurgery, TUTH, between 2019 April – 2023 April was done. The variables included were age, sex, clinical features, radiological findings, histopathological diagnosis, management and postoperative complications. Results: Twenty-four patients (30%) out of 80 childhood tumors were located in posterior fossa. The most common presenting symptoms was headache in 83.3% and vomiting in 75%. The most common location of tumour was the fourth ventricle in 66.7% while most common tumour histology was Type IV medulloblastoma in 45%. The commonest mode of treatment in 90% of cases was Ventriculoperitoneal (VP) shunting followed by surgical excision of tumour. Conclusion: Posterior fossa tumours are common tumour occurring in children. Majority of the patients presented with features of raised intracranial pressure and gait ataxia. Fourth ventricle and cerebellar vermis are the most common location. Most common histology types are medulloblastoma followed by pilocytic astrocytoma and ependymoma. Management involves addressing acute hydrocephalus followed by definitive surgery. Keywords: Medulloblastoma, Paediatrics, Posterior fossa, Surgery, Ventriculoperitoneal shunt

Abstract Background Incisional surgical site infection (SSI) is a significant source of postoperative morbidity resulting in increased length of stay and cost. In this study, our aim was to evaluate the association between thickness of subcutaneous fat (TSF) and incisional SSI among patients undergoing open appendectomy in low-resource settings. Methods 90 patients with acute uncomplicated appendicitis who underwent emergency open appendectomy from December 2017 to August 2018 were included in this prospective study. TSF was measured preoperatively using ultrasound. TSF and other possible predictors of incisional SSI, including body mass index and other clinical characteristics, were assessed by univariate and multivariable logistic regression analysis. Receiver operating characteristic (ROC) curve analysis evaluated the predictive value of TSF and the optimum cut-off value for TSF was determined using the Youden index. Results The prevalence of incisional SSI was 13.3% (12/90). TSF was independently associated with incisional SSI (P

Splenic flexure volvulus is rare and results from congenital or postoperative laxity of splenic attachments. A 34 year old female presented with features of large bowel obstruction due to splenic flexure volvulus. She underwent laparotomy with detorsion and colopexy of the volvulus.
