Incidence of hospital-admitted severe traumatic brain injury and in-hospital fatality rates in a Pacific Island country: a 5-year retrospective study.

BACKGROUND: Epidemiology of severe traumatic brain injury (TBI) is poorly defined in the Pacific region, including in New Caledonia. The aim of this study was to assess the incidence, causes and outcome of hospital-admitted severe TBI in the whole population of New Caledonia. METHODS: A retrospective study on patients with severe TBI admitted to the only trauma centre during the 5-year period (2008-2012) was performed. The electronic patient register was searched for diagnoses of intracranial injuries to identify patients. Severe TBI was defined as a Glasgow Coma Scale Score ≤ 8 during the first 24 hours after injury. RESULTS: The annual incidence ranged from 10/100 000 in 2010 to 15/100 000 in 2011. Road traffic accidents (n = 109; 71%), falls (n = 26; 17%) and assaults (n = 19; 12%) were causes of severe TBI. Young Melanesian adults (median age = 26 [19-36]) were the most affected. In ICU, the overall case-fatality rate was 25%. The mortality rate was the highest among victims of assaults (47%). CONCLUSIONS: The high incidence of hospital-admitted patients with severe TBI in this study combined with high in-ICU mortality rates supports the need for targeted public health action to prevent assaults and traffic road accidents in this vulnerable population.

Zika virus infection as an unexpected finding in a Leptospirosis patient.

INTRODUCTION: Areas where leptospirosis and arboviruses are endemic largely overlap in the tropics. However, the number of arbovirus infections is usually much higher. The initial clinical presentation can be highly confusing; therefore, laboratory confirmation is key to an accurate diagnosis. CASE PRESENTATION: A 19-year-old man presented to a peripheral health centre with an acute febrile illness. Dengue was initially suspected, but the patient deteriorated to a shock syndrome. Leptospirosis as well as a co-infection with Zika virus were both confirmed in the laboratory, the latter being clinically masked in this dual infection. CONCLUSION: This case highlights the importance of not only considering the differential diagnosis of acute febrile syndromes, but also to consider the possibility of dual infections in the context of global spread of arboviruses. The specific context of travellers returning from endemic areas and pregnant women is also highlighted and discussed.

Comparison of continuous 3-in-1 and fascia Iliaca compartment blocks for postoperative analgesia: feasibility, catheter migration, distribution of sensory block, and analgesic efficacy.

BACKGROUND AND OBJECTIVES: Efficacy and technical aspects of continuous 3-in-1 and fascia iliaca compartment blocks were compared. METHODS: Forty-four patients scheduled for cruciate ligament repair or femur surgery were randomly divided into 2 groups. After surgery with the patient anesthetized, catheters were placed for continuous 3-in-1 blocks by means of a nerve stimulator (group 1). In group 2, the catheter was inserted for continuous fascia iliaca compartment block without the use of a nerve stimulator. In both groups, a 5-mg/kg bolus of 0.5% ropivacaine was administered followed by continuous infusion of 0.1 mL/kg/h of 0.2% ropivacaine for 48 hours. In the postoperative period, all the patients received parenteral propacetamol (6 g daily) and ketoprofen (200 mg daily) and 0.1 mg/kg of subcutaneous morphine as rescue analgesia if the visual analog scale (VAS) pain values were greater than 30 mm. We evaluated the technical difficulties relative to catheter placement, the location of the catheter, the analgesic efficacy, and the distribution of the sensory block at 1 hour, 24 hours, and 48 hours. RESULTS: Catheter placement was faster in group 2, and the absence of nerve stimulation decreased material costs (P <.05). No significant difference was observed between groups concerning location of the catheter tip under the fascia iliaca. In both groups, the distribution of the sensory block and its course were similar except for those of the obturator nerve (more sensory blocks in group 1, P <.05). No significant difference was noted between the groups regarding median VAS pain values and consumption of morphine during the 48-hour period. No major side effect was observed. CONCLUSIONS: The authors conclude that a catheter for continuous lumbar plexus block can be placed more quickly and at lesser cost using the fascia iliaca technique than the perivascular technique with equivalent postoperative analgesic efficacy.
