Pharmacological management of post-traumatic seizures in a South African paediatric intensive care unit

Background. Traumatic brain injury (TBI) is a common cause of paediatric intensive care unit (PICU) admissions in South Africa. Optimal care of these patients includes the prevention and control of post-traumatic seizures (PTS) in order to minimise secondary brain injury. Objectives. To describe the demographics of children admitted to a South African PICU, to describe the characteristics of PTS, and to describe the prophylactic and therapeutic management of PTS within the unit. Method. A 3-year retrospective chart review was conducted at the PICU of the Chris Hani Baragwanath Academic Hospital (CHBAH) in Soweto, Johannesburg, from 1 July 2015 to 30 June 2018. Results. Seventy-eight patients were admitted to the PICU, all with severe TBI. A total of 66 patient files were available for analysis. The median age of admission was 6 years (interquartile range (IQR) 4 - 9) with the majority of trauma secondary to mechanical injury (89%). Prophylactic anti-epileptic drugs (AEDs) were initiated in 44 (79%) patients. Early PTS occurred in 11 (25%) patients who received prophylaxis and 4 (33%) who did not. Three (5%) patients developed late PTS, resulting in an overall incidence of PTS of 43%. The most common seizure type was generalised tonic clonic (82%). Children diagnosed with PTS were a median of 2 years younger than those without PTS, with increased prevalence of seizures (83% v. 38%) in children below 2 years of age. Maintenance therapy was initiated in all patients consistent with recommended dosages. Of the total 167 anti-epileptic levels taken during maintenance, only 56% were within target range. Of the initial 78 patients, 8 died (10%). The median length of stay was 7 (IQR 5 - 12) and 8 (IQR 8 - 24) days longer in ICU and hospital respectively, in children with PTS. Conclusion. PTS is a frequent complication of severe TBI in children. There was considerable variation in the approach to both prophylaxis and maintenance therapy of PTS in terms of choice of agent, dosage, frequency of drug monitoring and approach to subtherapeutic levels. It is clear that more high-level studies are required in order to better inform these practices

Trauma unit admissions at the Ugandan National Referral Hospital: a descriptive study

Background: Injuries are a neglected epidemic globally accounting for 9% global deaths; 1.7 times that of HIV, TB and malaria combined. Trauma remains overlooked with key research and data focusing on infectious diseases, yet Uganda has one of the highest rates of traumatic injury. We described demographics of patients admitted to Mulago Hospital's Shock Trauma Unit within the Emergency Department. Methods: This was a retrospective record review Trauma Unit admission from July 2012 to December 2015. Information collected included: age, sex, time of admission, indication for admission and mechanism of trauma. Results: 834 patient records were reviewed. The predominant age group was 18-35 with majority of patients being male. 54% of patients presented during daytime with 46% admitted in the evening hours or overnight. Mechanism of injury was documented in 484 cases. The most common mechanism was Road Traffic Accident (67.4%), followed by assault (12.8%) and mob violence (5.6%). The most common indication for admission was traumatic brain injury (84.5%), followed by hemodynamic instability (20.0%) and blunt chest injury (6.1%). Conclusion: There's a significant burden of high-acuity injury particularly among males with RTAs as the leading cause of admission associated with Traumatic Brain Injury as main admission indication

An overview of penetrating traumatic brain injuries at a major civilian trauma centre in South Africa

Background: This study reviews our experience with penetrating Traumatic Brain Injury (TBI) in order to define and describe the injury pattern and the outcome. A secondary aim of this study was to review the use of the Motor Score (M Score) and the Simplified Motor Score(SMS) to assess and triage patients with penetrating TBI. Methods: All patients with a TBI secondary to a penetrating mechanism were identified from the Hybrid Electronic Medical Registry at Pietermaritzburg Metropolitan Trauma Service (PMTS) from January 2012 to December 2014. Standard demographic data, need for neuro-surgical intervention, location of external wounds, CT findings and mortality where analysed. The Glasgow Coma Scale (GCS) M score and SMS score were specifically evaluated to determine the relationship between the individual motor component and patient outcome. Results: Over the two-year period January 2012­December 2014, a total of 384 patients were admitted following a penetrating TBI. There were 350 males and 34 females and of this total 7 (1.82%) died. The mechanism of injury was axe (30), bottle (34), gunshot wound (GSW)(22) and stab wound (298). The average age for axe injuries was 27 and bottle injuries was 30. The average age for firearms and knives was 29 and 30 respectively. Surgery was not required for 76.67% of patients. The need for surgery varied according to mechanism of injury. Axe injuries were treated non-operatively in 47.83%, bottle injuries in 87.50%, firearms 70% and knife injuries were treated non-operatively in 86.84% of cases.The overall survival rate for a penetrating head injury in this population is 98.16%. There were a total of 368 patients with a motor score of 6 of which one died. The survival rate was 99.7% and the mortality rate 0.3%. There were only 6 patients with a motor score of 5 and only 2 with a motor score of 4. The survival rate for both these groups was 100%. There was a total of 6 patients with a motor score of 1. There was a 100% mortality rate is this group. Conclusion: Penetrating TBI has a good prognosis. The vast majority of cases do not require neuro-surgical intervention. Poor motor score is associated with a poor outcome

Traumatic brain injury associated with hyponatremia

Background: Traumatic brain injury (TBI) is a one of the commonest injuries treated at the Neurosurgery Department. The incidence rate is approximately 3% in the general population and the mortality rate is about 30% of all injury deaths. Hyponatremia leads to high morbidity and/or mortality in TBI patients. Our study discusses the epidemiology of TBI associated with hyponatremia. Methods: Retrospective analysis of 80 patients with TBI between February 2017 and November 2018 was performed. The relationship between the incidence of hyponatremia in TBI patients and age, sex, GCS, type, severity of injury and whether the patient was submitted to surgery or not. Results: Out of 80 TBI patients recruited for the study, 25 of them suffered from hyponatremia. Hyponatremia following TBI wasn't related to age, sex but it was related to the type of injury, the Glasgow Coma Scale (GCS) score ≤ 8, surgical history. TBI with hyponatremia usually had longer stay in the hospital and bad outcome. Conclusions: Sever TBI patients (GCS score ≤ 8), intracranial hemorrhage and/or skull base fracture are susceptible to developing hyponatremia and require additional treatment aiming to normalization of serum sodium levels to prevent deterioration of their condition.

Some peculiar lesions of traumatic brain injuries encountered in our practice with brief discussion-imaging manuscript

The advent of neuroimaging like computed tomography and magnetic resonance imaging has facilitated the diagnosis of traumatic brain injuries. Emphasizing certain diagnostic features of some peculiar traumatic brain injuries. The following lesions of traumatic brain injuries were pictorially depicted, namely Tension pneumocephalus, Blow out orbit, Bilateral subacute subdural haematomata, Acute-onchronic subdural haematoma, Middle cranial fossa acute epidural haematoma, Traumatic basal ganglial haematoma and Acute intra-ventricular haematoma. Mount Fuji sign is typical of tension pneumocephalus while herniation of extra-ocular muscles into the maxillary sinus is diagnostic of blowout orbit. Rabbit ear appearance is observable in bilateral subacute subdural haematomata

Epidemio-clinical and CT-scan profile of adult headache disorders in a sub-Saharan Africa country

Objective: Given the little availability of MRI in sub-Saharan Africa, we carried out this study focusing on CT-scan in adult headache disorder, in order to determine epidemiological and clinical profile of adult patients undergoing CT-scan for headache disorder, and the organic pathologies discovered in sub-Saharan Africa.Method: We carried out a multicentric prospective cross-sectional study in medical imaging departments of Yaounde Central Hospital and Douala Laquintinie Hospital, which are two teaching hospitals in Cameroon. We consecutively and non-exhaustively included all consenting patients aged eighteen years or above, referred to radiology department to undergo a head CT-scan as aetiological workup of headache disorder, from either traumatic or non-traumatic mechanism. Patients with a Glasgow coma scale less than thirteen were excluded. We interviewed eligible patients, and performed a neurological examination and a complete physical examination before they underwent head CT-scan. The scanning was performed using a brand HITACHI ECLOS 16 slices CT-scan, in helical mode with or without contrast enhancement according to the clinical context. The reading was done by experimented radiologists

The spectrum and outcome of paediatric traumatic brain injury in KwaZulu-Natal Province, South Africa has not changed over the last two decades

Objectives. This retrospective review of a prospectively entered and maintained hybrid electronic trauma registry was intended to develop a comprehensive overview of traumatic brain injury (TBI) in children and adolescents and to compare it with previous audits from our local environment and from other developing world centres. All TBI patients admitted to hospital were included in this study. We reviewed the age, gender, outcomes, radiological findings and treatment of the patients.Methods. All patients aged ≤18 years old who were admitted by the Pietermaritzburg Metropolitan Trauma Service (PMTS) with TBI between December 2012 and December 2016 were included in this audit. Results. During the 4-year period under review, a total of 563 children and adolescents were treated for TBI by the PMTS. The median age was 6.4 years and 29% (n=165) were females. The mechanism of TBI was blunt trauma in 96% (n=544) of cases, with 4% (n=19) suffering penetrating trauma. The penetrating mechanisms included impalement by a cow horn and miscellaneous injuries due to saws, axes, barbed wire, spades, stones and knives. The blunt mechanisms included falls (n=102), assaults (n=108), collapse of a building (n=28), bicycle-related injury (n=14), falling off a moving vehicle (n=280), motor vehicle accident (MVA; n=59), pedestrian vehicle accident (PVA; n=183) and animal-related injuries (n=8). There were 454 (80%) mild, 67 (12%) moderate and 42 (7%) severe cases of TBI. A total of 48 patients were admitted to the intensive care unit and 23 were admitted to the high care unit. Nine patients died. All the deaths were in the MVA and PVA group. The spectrum of TBI as diagnosed on computed tomography scans was nonspecific cerebral contusion (n=92), depressed skull fracture (n=70), sub-arachnoid haemorrhage (n=60), extradural haemorrhage (n=41), intracerebral haemorrhage (n=19), free air (n=19), subdural haemorrhage (n=13), intraventricular haemorrhage (n=9). A total of 62 (11%) patients required surgery.Conclusion. There is a significant burden of paediatric TBI in Pietermaritzburg. The majority of TBI was related to blunt trauma and assaults were very common. Although the short-term outcomes are good, the long-term consequences are poorly understood. Injury prevention programmes are needed to help reduce this burden of disease and a nationwide trauma registry is long overdue
