Review of adult head injury admissions into the intensive care unit of a tertiary hospital in Nigeria

Background: Head injury is frequently associated with death and disability and imposes considerable demands on health services. Outcome after head injury is closely related to prompt management, including prevention of secondary brain injury and intensive care unit (ICU) management. This study aimed at determining the aetiological spectrum, injury characteristics, ICU admission patterns, and treatment outcomes of adult head-injured patients at a sub-Saharan tertiary hospital.Methods: A retrospective study on adult head-injured patients admitted to the ICU of a sub-Saharan tertiary hospital between July 2000 and June 2010.Results: A total of 198 head-injured adult patients were managed in the ICU during the study period. This included 128 males and 70 females with a male-to-female ratio of 1.8:1. The most common mode of injury was road traffic accident. All the patients admitted to ICU had either moderate or severe head injury, with 73.7% having severe head injury. About 26.3% of the patients had associated cervical spine injuries and 50% had various musculoskeletal and soft tissue injuries. Cranial computed tomography findings included brain contusions and intracranial haematomas. Mean duration of ICU stay was 18 days (range 24 hours-42 days), with 89.9% discharged out of ICU care. The overall mortality was 10.1%, although only 36.9% had satisfactory outcomes, as determined by the Glasgow Outcome Scale. Outcome had statistically significant (P < 0.05) relationship with severity of head injury and surgical intervention.Conclusions: Head injury management in the ICU requires an approach to ensure prevention of secondary brain injury; appropriate and early neuroimaging to diagnose lesions that would benefit from timely surgical intervention; as well as management of fluid, electrolyte and haematological derangements.Keywords: head injury; admissions; IC

Carbapenem resistance expressed by Gram-negative bacilli isolated from a cohort of Libyan patients

Background and objectives: Carbapenem-resistant Enterobacteriaceae (CRE) and other Gram-negative bacteria are among the most common pathogens responsible for both community and hospital acquired infection. The global spread of cephalosporinases in Enterobacteriaceae has led to the increased use of carbapenems resulting in the emergence and rapid spread of CRE. This has become an alarming public health concern, yet the condition in Libya remains unclear. The aim of this study was to obtain a better understanding of CRE strains prevalent in Libyan patients by investigating their phenotypic characteristics and antibiograms. Methods: Gram-negative bacterial species were collected from Misrata Central Hospital, Misrata Cancer Centre and Privet Pathology Laboratories. Clinical samples and swabs were obtained from hospitalised and non-hospitalised patients and from mechanical ventilation and suction machines. Patients who had received antibiotic therapy for at least three days prior to the study were excluded. The identification and characterization of the isolated species were achieved using the growth characteristics on MacConkey and blood agar, spot tests and API 20E or API 20NE biochemical testing systems. Screening for carbapenem resistance was performed using the disk diffusion method with carbapenem 10 μg and cephalosporin 30 μg disks and minimum inhibitory concentrations (MIC) determined using the Sensititre Gram-negative Xtra plate format (GNX2F). All strains demonstrating resistance or reduced susceptibility to one of the four carbapenems were subjected to carbapenememase activity detection using the RAPIDEC CARBA NP test, Modified Hodge test and carbapenem inactivation methods. Results: A total of one hundred and forty isolates representing fourteen bacterial species were isolated from 140 non-duplicated specimens. Clinical specimens included urine samples (96/140, 68.57%), sputum (15/140, 10.71%), surgical wound swabs (18/140, 12.85%), foot swabs from diabetes mellitus (DM) patients (6/140, 4.29%), ear swabs (3/140, 2.14%) and wound swabs (2/140, 1.43%). Thirty-four (24.29%) isolates demonstrated resistance to at least one of the four carbapenems with Klebsiella pneumoniae representing 73.53% (25 isolates) of all carbapenem resistant species, followed by 8.82% for Pseudomonas aeruginosa (3 isolates), 5.88% for both Proteus mirabilis (2 isolates) and Escherichia coli (2 isolates) and 2.94% for both Citrobacter koseri (1 isolate) and Rahnella aquatilis (1 isolate). The other isolates were either susceptible or cephalosporinase producers. Conclusion: This study has revealed the high rate of carbapenem resistance amongst Libyan patients and emphasizes the crucial need for accurate screening, identification and susceptibility testing to prevent further spread of nosocomial and community acquired resistance. This may be achieved through the establishment of antibiotic stewardship programmes along with firm infection control practices.National Research Foundation of South Africa; Libyan GovernmentWeb of Scienc

Comparative study of mental health and quality of life in long term refugees and host populations in Oru-Ijebu, Southwest Nigeria

Abstract Background Refugees as “People Living in Highly Stressful Situation” are particularly vulnerable to mental ill-health as a result of the trauma experienced pre- and post-migration. The lack of information on the mental health disparities of refugees and non-refugees in West Africa is what this study aimed to bridge. A cross-sectional study design was employed using a cluster sampling technique. Interviewer-administered structured questionnaires consisting of the Mini-International Neuropsychiatric Interview (MINI), WHO quality of life (WHOQOL-BREF) and the Community Quality of Life (CQoL) were used for data collection. Data were analyzed with SPSS version 17. Logistic regression analysis was used to determine the predictors of mental health status and QoL. Results Respondents consisted of 444(45.7%) refugees and 527(54.3%) non-refugees. Two-thirds 292 (66%) of the refugees were Liberians. Mean age: refugees - 34.8 ± 12.8 years versus non-refugees - 33.3 ± 8.1 years (p  Conclusions QoL and occupational status were the major threats to the mental health of the refugees. Results of this study point to the need for continued attention to not only the healthcare needs but the welfare, housing, employment and overall QoL to support the long-term mental health of refugees and non-refugee populations alike.</p
