Cerebrospinal fluid external leak after penetrating trauma in a neurologic intact infant patient: a case report.

Cranial cerebrospinal fluid (CSF) leak is an extremely rare complication of blunt head trauma causing skull fractures, especially fractures involving the skull base. We present the case of a 10-month-old male who received glass fragments on the midline and posterior tier of his anterior fontanelle producing a cranial cerebrospinal fluid leak without any skull fracture or symptoms. Neurologic exam was completely normal and a superficial stitch wound repair was performed. He was observed for 24 h, had no antibiotic, and left with a 1-week outpatient neurosurgical follow-up. The patient had no negative outcome. Cerebrospinal fluid leak should be included in the differential diagnosis of a head trauma in a patient with open fontanelles. No similar case was found in literature.

Should We Use Bipolar Hemiarthroplasty in Patients ≥70 Years Old With a Femoral Neck Fracture? A Review of Literature and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Bipolar (BHA) and unipolar hemiarthroplasties (UHA) are interchangeably used in elderly patients with a displaced femoral neck fracture. We ask if there is a difference between BHA and UHA with regards to hip function, in elderly patients. METHODS: Systematic review and meta-analysis was conducted of randomized controlled trials comparing BHA to UHA. The primary outcome was postoperative hip function scores. Secondary outcomes were overall health-related quality of life patient-reported outcomes, acetabular erosion, and postoperative complications. Data sources, last searched on June 1, 2020, were MEDLINE, EMBASE, Cochrane Library, and Web of Science. RESULTS: Fourteen randomized controlled trials were eligible for meta-analysis. There was no difference in hip function scores between BHA and UHA (standardized mean difference 0.32, 95% confidence interval [CI] -0.06 to 0.71, n = 1084, I2 = 87%). Patients with BHA with more than 2-year follow-up had better hip function scores (standardized mean difference 0.68, 95% CI 0.18-1.18, n = 700, I2 = 87%). There was no difference in European Quality of life- five dimensions scores with BHA (mean difference 0.08, 95% CI -0.01 to 0.17, n = 967, I2 = 82%). The use of BHA decreased the risk of acetabular erosion (relative risk 0.38, 95% CI 0.17-0.83, n = 1239, I2 = 0%). There was no difference for revision, mortality, infection, and dislocation (I2 = 0%). CONCLUSION: There seems to be no difference between BHA and UHA with regards to hip function at 2 years. BHA might decrease the risk of acetabular erosion. There is a need for a large randomized controlled trial with a follow-up >2 years and better measurement tools to assess clinical benefits. LEVEL OF EVIDENCE: II.

Adapting the Canadian CT head rule age criteria for mild traumatic brain injury.

OBJECTIVE: With the ageing population, the prevalence of mild traumatic brain injury (mTBI) among older patients is increasing, and the age criteria of the Canadian CT head rule (CCHR) is challenged by many emergency physicians. We modified the age criteria of the CCHR to evaluate its predictive capacity. METHODS: We conducted a retrospective cohort study at a level 1 trauma centre ED of all mTBI patients 65 years old and over with an mTBI between 2010 and 2014. Main outcome was a clinically important brain injury (CIBI) reported on CT. The clinical and radiological data collection was standardised. Univariate analyses were performed to measure the predictive capacities of different age cut-offs at 70, 75 and 80 years old. RESULTS: 104 confirmed mTBI were included; CT scan identified 32 (30.8%) CIBI. Sensitivity and specificity (95% CI) of the CCHR were 100% (89.1 to 100) and 4.2% (0.9 to 11.7) for a modified criteria of 70 years old; 100% (89.1 to 100) and 13.9% (6.9 to 24.1) for 75 years old; and 90.6% (75.0 to 98.0) and 23.6% (14.4 to 35.1) for 80 years old. Furthermore, modifying the age criteria to 75 years old showed a reduction of CT up to 25% (n=10/41) among the individuals aged 65-74 without missing CIBI. CONCLUSION: Adjusting the age criteria of the Canadian CT head rule to 75 years old could be safe while reducing radiation and ED resources. A future prospective study is suggested to confirm the proposed modification.
