Management of penetrating brain injury.

Penetrating brain injury (PBI), though less prevalent than closed head trauma, carries a worse prognosis. The publication of Guidelines for the Management of Penetrating Brain Injury in 2001, attempted to standardize the management of PBI. This paper provides a precise and updated account of the medical and surgical management of these unique injuries which still present a significant challenge to practicing neurosurgeons worldwide. The management algorithms presented in this document are based on Guidelines for the Management of Penetrating Brain Injury and the recommendations are from literature published after 2001. Optimum management of PBI requires adequate comprehension of mechanism and pathophysiology of injury. Based on current evidence, we recommend computed tomography scanning as the neuroradiologic modality of choice for PBI patients. Cerebral angiography is recommended in patients with PBI, where there is a high suspicion of vascular injury. It is still debatable whether craniectomy or craniotomy is the best approach in PBI patients. The recent trend is toward a less aggressive debridement of deep-seated bone and missile fragments and a more aggressive antibiotic prophylaxis in an effort to improve outcomes. Cerebrospinal fluid (CSF) leaks are common in PBI patients and surgical correction is recommended for those which do not close spontaneously or are refractory to CSF diversion through a ventricular or lumbar drain. The risk of post-traumatic epilepsy after PBI is high, and therefore, the use of prophylactic anticonvulsants is recommended. Advanced age, suicide attempts, associated coagulopathy, Glasgow coma scale score of 3 with bilaterally fixed and dilated pupils, and high initial intracranial pressure have been correlated with worse outcomes in PBI patients.

Cost-effectiveness of clipping vs coiling of intracranial aneurysms after subarachnoid hemorrhage in a developing country - a prospective study.

BACKGROUND Endovascular coil treatment is being used increasingly as an alternative to clipping for some ruptured intracranial aneurysms. The relative benefits of these 2 approaches have yet to be fully established. The aim of this study was to compare the clinical outcome, resource consumption, and cost-effectiveness of endovascular treatment vs surgical clipping in a developing country. METHODS The study population consisted of 55 patients with aneurysmal subarachnoid hemorrhage (SAH) identified prospectively from January 2004 to June 2007. Of the 55 patients with ruptured intracranial aneurysms, 31 underwent surgical clipping, whereas 24 were treated via interventional coils. Clinical outcome at 6 months, using the modified Rankin Scale, and cost of treatment related to all aspects of the inpatient stay were evaluated in both groups. RESULTS The average age of the patients in the endovascular group was 38 years, whereas in the surgical group, it was 45 years. Most patients (43) were found to be in grades (1 and 2). Of these patients, 18 received coils and 25 were clipped. The remaining 12 patients were of poor grades (3 and 4), of which 6 had coiling and 6 underwent clipping. Most the patients (46/55) had anterior circulation aneurysms, and the rest of the patients (9/55) had posterior circulation aneurysms. The clinical outcome was similar in comparison (good in 81% for clipping and 83% for coiling). The average total cost for patients undergoing endovascular treatment of the aneurysms was

The benefits of apparent decrease in length of stay in the endovascular group were offset by higher procedure price and cost of consumables. There was no significant difference in clinical outcome at 6 months. We have proposed a risk scoring system to give guidelines regarding the choice of treatment considering size of aneurysm and resource allocation.

Safety of untreated autologous cranioplasty after extracorporeal storage at -26 degrees Celsius.

The authors report a rare case of extensive spinal epidural abscess in an immunocompromised young woman. The patient presented with low-grade fever, back pain, and progressive lower limb weakness. The MR imaging of her whole spine revealed an epidural abscess extending from C-1 to the sacrum. She was treated using a minimally invasive surgical technique and showed excellent recovery. The authors review the current literature along with different modes of surgical treatment available for this unusual clinical entity.

Cerebrospinal fluid rhinorrhea: An institutional perspective from Pakistan.

Background: Early tracheostomy (ET) has been shown to be effective in reducing complications associated with prolong mechanical ventilation. The study was carried out to evaluate the role of ET in reducing the duration of mechanical ventilation, duration of intensive care unit (ICU) stay, ICU-related morbidities, and its overall effect on outcome, in patients with isolated severe traumatic brain injury (TBI). Methods: This 7-year review included 100 ICU patients with isolated severe TBI requiring mechanical ventilation. ET was defined as tracheostomy within 7 days of TBI, and prolonged endotracheal intubation (EI) as EI exceeding 7 days of TBI. Of 100 patients, 49 underwent ET and 51 remained on prolong EI for ventilation. All patients were comparable in term of age and initial Glasgow Coma Scale (GCS). We evaluated groups regarding clinical outcome in terms of ventilator-associated pneumonia (VAP), ICU stay, and Glasgow Outcome Score (GOS). Results: The frequency of VAP was higher in EI group relative to ET group (63% vs. 45%, P value 0.09). ET group showed significantly less ventilator days (10 days vs. 13 days, P value 0.031), ICU stay (11 days vs. 13 days, P value 0.030), complication rate (14% vs. 18%), and mortality (8.2% vs. 17.6%). Clinical outcome assessed on the basis of GOS was also better in the ET group. Total inpatient cost was also considerably less (USD

Long-tunneled versus short-tunneled external ventricular drainage: Prospective experience from a developing country.

Abstract Background. Given the improved survival of patients requiring decompressive craniectomies, the frequency of subsequent cranioplasties are on the rise. The most feared complication of autologous cranioplasty is infection and one method for reducing the rate of infection, is to store the bone flaps at subnormal temperatures. However, to date there is no defined temperature for flap storage and temperature ranges from − 18 to − 83°C have been described in literature. Considering our limited resources it has been the practice at our center to store bone flaps at − 26°C. In this study, we have retrospectively reviewed our practice and have audited this choice of temperature with respect to the frequency of infections. Methods. A retrospective review was conducted for all cranioplasties performed at our center between January 2001 to March 2011, using autologous bone which was cryopreserved according to institutional protocol. During this period the operative and cryopreservation protocol remained the same. All patient records including charts, notes and laboratory findings were reviewed with a specific focus to identify infections. Results. Of the 88 patients included in the study, only 3 (3.40%) patients were found to show signs of infection. Of these, two patients had superficial surgical site infections which resolved with oral antibiotics (Co-Amoxiclav 1 gm BD for 7 days). However the third patient developed deep surgical site infection requiring re-exploration and washout. All three patients had complete resolution of infection with preservation of autologous bone. Conclusion. Despite our method of keeping the bone flap in freezer at − 26°C we have reported an acceptable rate of infection and raised the notion whether there is a justification for sophisticated and costly equipment for bone flap preservation, especially in resource depleted setups.

Low Prevalence Of Colorectal Cancer In South Asians Than White Population In Uk: Probable Factors

Background: The management of cerebrospinal fluid (CSF) rhinorrhea has evolved over the last two decades. We present here a review of our 11-year data on CSF rhinorrhea and its management at a tertiary care hospital in a developing country, with particular reference to the diagnosis, surgical management and outcome of the disease. Methods: The medical charts of all patients with a diagnosis of CSF rhinorrhea over an 11-year period were reviewed. The etiology of CSF rhinorrhea was classified into three categories: spontaneous, iatrogenic and traumatic. All the patients were divided into three categories based on the type of management as conservative, intracranial and transnasal endoscopic groups. Results: A total of 43 patients fulfilled our inclusion criteria and were included in the final analysis. Eleven of the 43 patients were managed conservatively, while 22 underwent intracranial repairs; 10 patients had transnasal endoscopic repairs. The primary success rate for the transnasal approach was 70% compared to 86% for the intracranial repair. Blood loss, special care unit (SCU) stay and total cost were found to be significantly less in the transnasal endoscopic group. Computed tomography (CT) cisternography was found to have the highest sensitivity and specificity. Further, no postoperative complications were found in the transnasal endoscopic group, while five patients from the intracranial group developed various complications. Conclusions: We conclude that the transnasal endoscopic approach has comparable success rates with the intracranial approach and significantly lower morbidity.
