Challenges to Thrombolysis in A Resource-Poor Setting- A Case Report.

A major complication of acute ischemic stroke is death and disability. The emergence of reperfusion therapy in form of thrombolysis and endovascular thrombectomy has led to the reversal of this trend in high-income countries. Low- and middle-income countries are yet to benefit maximally from these time-bound treatment options due to some limitations. We intend to highlight some of these in this report. We report an 80-year-old male patient with hypertension and firstdegree AV block admitted 3 hours after the onset of stroke with National Institutes of Health Stroke Scale (NIHSS) score of 13 and Medical Research Council (MRC) muscle power grade 3 in both the left upper and lower limb. Urgent non-contrast brain CT revealed no evidence of hemorrhage. Intravenous tissue plasminogen activator (tPA) was administered at a dose of 0.6 mg/kg 9 hours after symptom onset. He made significant improvement afterward and was discharged. The challenges encountered in his management include prehospital and intrahospital delay, and unavailability of tissue plasminogen activator. There is a need for an improved healthcare delivery system in order to reduce the morbidity associated with acute ischemic stroke.

Une complication majeure de l'accident vasculaire cérébral ischémique aigu est le décès et l'invalidité. L'émergence de la thérapie de reperfusion sous forme de thrombolyse et de thrombectomie endovasculaire a conduit à l'inversion de cette tendance dans les pays à revenu élevé. Les pays à revenu faible et moyen n'ont pas encore pleinement bénéficié de ces options de traitement limitées dans le temps en raison de certaines limitations. Nous avons l'intention de mettre en lumière certaines de ces limitations dans ce rapport. Nous rapportons le cas d'un homme de 80 ans, connu pour son hypertension et un bloc auriculo-ventriculaire de premier degré, admis 3 heures après le début de l'accident vasculaire cérébral avec un score de 13 à l'échelle d'AVC des National Institutes of Health (NIHSS) et une force musculaire du Medical Research Council (MRC) de grade 3 dans les membres supérieurs et inférieurs gauches. Une tomodensitométrie cérébrale urgente sans produit de contraste n'a révélé aucune preuve d'hémorragie. De l'activateur tissulaire du plasminogène (tPA) par voie intraveineuse a été administré à une dose de 0,6 mg/kg 9 heures après le début des symptômes. Il a ensuite connu une amélioration significative et a été autorisé à quitter l'établissement. Les défis rencontrés dans sa prise en charge comprenaient des retards préhospitaliers et intrahospitaliers, ainsi que l'indisponibilité de l'activateur tissulaire du plasminogène. Il est nécessaire d'améliorer le système de prestation de soins de santé afin de réduire la morbidité associée à l'accident vasculaire cérébral ischémique aigu. MOTS-CLÉS: Ischémique, AVC, Thrombolyse, Tissu, Plasminogène, Thrombectomie.

Neurocritical Care in Nigeria.

Nigeria is the most populous country in Africa with an estimated 206 million inhabitants served by less than 300 neurologists and 131 neurosurgeons. Neurological conditions account for approximately 18% of all medical emergencies. Neurocritical care challenges in Nigeria are as complex as they are in other low-to-middle-income countries (LMICs). These include high burden of neurological diseases, poor pre-hospital care, delays in transfer, lack of neurocritical care equipment, and inadequate rehabilitative capacity. Neurocritical care units in Nigeria offer mostly limited multimodal monitoring due to out-of-pocket payment, and the success of repeat radiological imaging and blood work is low. Data gathering and outcome research in neurocritical conditions can help in clinical decision-making and enhance cost-effective clinical care. The concept of allocation requires that when medical resources are scarce, they must be efficiently utilized in the most judicious way so as to achieve the greatest possible benefit. A high degree of transparency is needed with regard to the principles, values and criteria employed to facilitate such triage decisions. Proper funding will help improve availability of equipment and drugs resulting in a higher quality of care and, subsequently, improvement in mortality. There is ample evidence that neurocritical care improves overall prognosis in neurocritically-ill patients. Neurocritical care units (NCCUs) are mostly unavailable in Nigeria, often resulting in poorer prognosis for patients. What is already known: Nigeria has an unacceptably huge deficit in the overall capacity for neurocritical care. The inadequacies affect a wide range of components - facilities, quantity and quality of personnel, and the unbearably high cost, among others. What this study adds: This article attempts to condense the challenges in one piece while highlighting previously obscure ones, with the aim of providing possible solutions to the lingering challenges in neurocritical care in Nigeria and, invariably, other LMICs. How this study might affect practice, policies or research: We envisage this article will stimulate the initial steps in a multipronged and data-driven approach to bridging the gap by government and relevant healthcare administrators.

Le Nigeria est le pays le plus peuplé d'Afrique avec une population estimée à 206 millions d'habitants et à peine moins de 300 neurologues et 131 neurochirurgiens au service de cette population. Les urgences neurologiques représentent environ 18 % de toutes les urgences médicales. Les défis posés par les soins neurocritiques au Nigeria sont aussi complexes que dans d'autres pays à revenu faible ou intermédiaire (PRFI). Il s'agit notamment du lourd fardeau des maladies neurologiques, de la médiocrité des soins préhospitaliers, des retards de transfert, du manque d'équipements de soins neurocritiques et d'une capacité de réadaptation réduite. Les unités de soins neurocritiques au Nigeria disposent d'une surveillance multimodale limitée en raison du paiement direct, et le succès de la répétition de l'imagerie radiologique et des analyses sanguines est faible. La collecte de données et la recherche sur les résultats dans les conditions neurocritiques peuvent aider à la prise de décision clinique et améliorer la rentabilité des soins cliniques. Selon le concept d'allocation, lorsque les ressources médicales sont rares, elles doivent être utilisées efficacement et de la manière la plus judicieuse possible afin d'obtenir le plus grand bénéfice possible. Un degré élevé de transparence est nécessaire en ce qui concerne les principes, les valeurs et les critères utilisés pour faciliter ces décisions de triage. Un financement adéquat permettra d'améliorer la disponibilité des équipements et des médicaments, ce qui se traduira par une meilleure qualité des soins et, par la suite, par une réduction de la mortalité. Il existe de nombreuses preuves que les soins neurocritiques améliorent le pronostic général des patients en état neurocritique. Les unités de soins neurocritiques (NCCU) sont pour la plupart indisponibles au Nigeria, ce qui entraîne un pronostic plus défavorable. Ce que l'on sait déjà : Le Nigeria souffre d'un déficit inacceptable en matière de capacité globale de soins neurocritiques. Les insuffisances touchent un large éventail d'éléments - installations, quantité et qualité du personnel, et coût insupportablement élevé, entre autres. Ce que cette étude apporte : Cet article tente de condenser les défis en un seul élément tout en mettant en lumière ceux qui étaient auparavant obscurs, dans le but de fournir des solutions possibles aux défis persistants des soins neurocritiques au Nigeria et invariablement dans les pays à faible revenu intermédiaire. Comment cette étude pourrait-elle affecter la pratique, les politiques ou la recherche ? Nous pensons que cet article stimulera les premières étapes d'une approche multidimensionnelle et axée sur les données pour combler le fossé par le gouvernement et les administrateurs de soins de santé concernés.

Tramadol-Induced Acute Seizures: A Report of Three Cases.

There is a rise in substance abuse in Nigeria and prescription drugs, particularly opioid analgesics, which are increasingly becoming a target of abuse. Abuse of the opiod tramadol has the potential to precipitate seizures. We present 3 cases of tramadol-induced seizures presenting at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. The three patients were men, aged 22-40 years and abused other drugs including alcohol, cannabis and Rohypnol. This report illustrates the fact that tramadol abuse may be associated with acute seizures and it is reasonable to consider drug/opiod-induced seizure in every case of unexplained first episode of seizure in a young adult.

L'abus de substances psychoactives est en hausse au Nigeria et les médicaments sur ordonnance, en particulier les analgésiques opioïdes, qui deviennent de plus en plus une cible d'abus. L'abus de l'opioïde tramadol a le potentiel de précipiter des crises d'épilepsie. Nous présentons 3 cas de crises d'épilepsie induites par le tramadol se présentant à Complexe hospitalier universitaire Obafemi Awolowo, Ile-Ife. Les trois patients étaient des hommes, âgés de 22 à 40 ans et abusaient d'autres drogues dont l'alcool, le cannabis et le Rohypnol. Ce rapport illustre le fait que l'abus de tramadol peut être associé à des crises aiguës. associé à des crises d'épilepsie aiguës et il est raisonnable d'envisager une crise induite par le médicament ou par une période dans tous les cas de premier épisode de crise inexpliqué chez un jeune adulte.

Cardiac autonomic neuropathy in adult epilepsy patients in a tertiary hospital in South-Western Nigeria.

BACKGROUND: Cardiac autonomic neuropathy (CAN) resulting from seizures has been implicated in sudden unexpected death in epilepsy in persons with epilepsy (PWE), however, there are no previous studies of CAN in PWE from Nigeria. OBJECTIVES: This study sought to determine the frequency and pattern of CAN in adult PWE in a tertiary hospital in South-western Nigeria and to determine the relationship between seizure variables and CAN. METHODS: A cross-sectional study of 80 adult PWE and 80 matched controls aged between 18 and 60 years was carried out between March 2012 and June 2013 at the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Demographic and clinical data were obtained from all the study participants. Anxiety was excluded using the Hamilton Anxiety Scale. Those with conditions that could affect autonomic function, such as chronic renal failure, heart failure, Parkinson's disease, diabetes mellitus, anxiety, and psychiatric disorders and pregnant women were excluded. Five bedside cardiovascular reflex tests were performed on each subject after baseline heart rate and blood pressure (BP) had been recorded. RESULTS: The mean age of onset of epilepsy was 19 ± 10 years, whereas the mean duration of epilepsy was 10 ± 8 years. The mean seizure frequency was 14 ± 30 per month (median three seizures per month). Of the 80 patients evaluated, 42 (52.5%) had CAN, whereas none of the controls had CAN. Majority (69%) of the PWE with CAN had purely parasympathetic dysfunction, whereas 3% had purely sympathetic dysfunction and 10% had combined autonomic dysfunction. The PWE in this study had significantly lower tilt ratios and diastolic BP change with Isometric Hand grip as well as significantly higher systolic BP change on standing than the controls. Patients who had more than four seizures per month had higher odds of CAN than those with less frequent seizures (odds ratio 0.275, P value 0.023). Also, patients who had received treatment for less than 10 years were found to have greater odds of CAN than those who had received treatment for a longer period (odds ratio 11.676, P value 0.046). CONCLUSION: CAN is common in adult PWE in South-Western Nigeria and the major predictors are short duration of treatment and frequent seizure episodes. Routine screening of these patients may help with early detection of autonomic dysfunction and provide an opportunity for intervention.

Percutaneous Endoscopic Gastrostomy in Ile-Ife, Nigeria:An Initial Report.

BACKGROUND: Protein-energy malnutrition is a common problem in critically ill patient and it is a major cause of accelerated morbidity and mortality in this group of patients. Recent dramatic advances in both enteral and parenteral nutritional support have ensured that most of these critically ill patients are adequately nutritionally supported. Unfortunately, most of these advancements in nutritional supports are far from the reach of most patients in developing countries. In this report, we highlighted the indications, success, challenges of the use of percutaneous endoscopic gastrostomy (PEG) in Nigeria patients. PATIENTS AND METHODS: All cases of PEG performed at the Endoscopy Unit of Obafemi Awolowo University Teaching Hospitals complex, Ile-Ife, Osun State from January 2011 and June 2012 were recruited into the study. The data obtained included the sociodemographic parameters, indication and duration of the procedure, complications, and follow up. RESULTS: During the 18 months study period 645 upper gastrointestinal endoscopic procedures were performed. Majority [601(93.2%)] of the cases were for diagnostic purposes. Six (0.9%) cases of PEG were performed. Most (5 of 6) of the patients had central nervous system impairment while only one had severe chronic facial infection with naso-oral fistula. The median age of patients was 60.5 years. The entire procedure including endoscopy lasted an average of 25 minutes with a range of 12-35 minutes. Only one case had peristoma infection which resolved with antibiotics and repeated dressing with povidone iodine. There was no episode of aspiration pneumonitis or procedure related mortality. The average follow up was 6 months with variable weight gain during the follow up period. CONCLUSION: PEG is a simple, cost effective and safe method to rehabilitate nutritionally all chronically ill patients in less developed countries such as Nigeria. The need to increase awareness and acceptability of PEG among physicians managing such patients and the society cannot be overemphasized.

The distribution and pattern of neurological disease in a neurology clinic in Ile-Ife, Nigeria.

BACKGROUND: Neurological disorders are common and contribute significantly to disease burden, disability-adjusted life years and death. OBJECTIVE: To assess the distribution of neurological disease in patients presenting to our hospital. METHODS: The records of the Adult Neurology Clinic in Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Osun state, Nigeria were reviewed retrospectively for the years 2003-2005 and 2010-2014, and diagnoses as made by the Consultant were obtained and analyzed. RESULTS: The total number of complaints was 1,524 and 86.4% of these were neurological in nature. Episodic and paroxysmal disorders (ICD-10) accounted for 54.1% of the diagnoses, and epilepsy and stroke were the most common of these. Of the 1,226 patients seen during the period, 91.4% had neurological disorders. The peak occurrence of these disorders was within the first three decades of life. CONCLUSION: Epilepsy and stroke are the commonest neurological disorders in the outpatient setting and there should be more studies in the community on their prevalence and impact.

Stroke risk factors among participants of a world stroke day awareness program in South-Western Nigeria.

INTRODUCTION: Stroke is a major cause of death and disability in population across the world. Hypertension is the most common stroke risk factor globally as well as in the Nigerian population, however other modifiable risk factors such as obesity are becoming increasingly prevalent due to unhealthy diets and sedentary lifestyle. MATERIALS AND METHODS: We screened 224 volunteers from Ile-Ife during the 2011 and 2012 world stroke day commemorative activities. Blood pressures (BP) were measured and body mass index (BMI) was determined from weight and height measurements. The data from 40 (18%) were incomplete and were excluded from further analysis. RESULTS: The 184 subjects eligible for analysis comprised 85 males (46.2%) and 99 females (53.8%), with a male to female ratio of 0.85:1. Their ages ranged from 16 to 95 years (mean, 53±16 years). 25% of the study population had stage 1 or 2 hypertension (mean systolic blood pressure: 127±27 mmHg, mean diastolic blood pressure: 78±16 mmHg), while 34.8% and 14.7% were overweight and obese, respectively (mean BMI: 25.8±5.0 kg/m2). CONCLUSION: Stroke risk factors such as hypertension and obesity were common among the participants of the world stroke day awareness program in an urban area of Nigeria. Community screening and modification of these risk factors should be intensified in order to reduce stroke morbidity and mortality.

Patients' knowledge about their disorder: perspective of patients with epilepsy in a tertiary health facility in southwestern Nigeria.

OBJECTIVE: Previous studies have shown that patients with epilepsy do not have adequate knowledge about their disorder, suggesting that patient education is a vital part of comprehensive care for epilepsy. The goal of this study was to evaluate what Nigerian patients with epilepsy know about their disorder. METHODS: Forty-six patients with EEG- and clinically confirmed epilepsy participated in the study. The patients completed the Epilepsy Patients Knowledge Questionnaire. The questionnaire includes topics related to etiology of epilepsy, safety, compliance, legal issues of driving, and employment. The questionnaire scores were correlated with demographic variables, duration of epilepsy, and level of education of the patients. RESULTS: The mean age of the respondents was 26.78 ± 9.27 years; there were 27 males and 19 females. The mean duration of epilepsy in the group was 7.6 ± 7.5 years. The mean rates of correct responses to the issues of safety and compliance were 31.6 and 76.8%, respectively. The mean scores on legal issues of driving and employment were 45.7 and 42.4%, respectively. The lowest score (10.9%) was on the etiology of epilepsy. CONCLUSION: Nigerian patients with epilepsy lack adequate knowledge about their disorder, and there is a need for improved educational intervention in these patients.

Supervised domain generalization for integration of disparate scalp EEG datasets for automatic epileptic seizure detection.

Numerous automatic epileptic seizure detectors (ESDs) with excellent performances have been reported, but they generally experience performance degradation when tested with real-life clinical data. This has been blamed on the scarcity of high-quality training data, which leads to models that generalize poorly. There is consequently interest in methods to improve the quality and quantity of training data for ESDs. This study used a domain generalization approach to combine data from two different datasets for training an ESD, which was thereafter tested on a third dataset. A subspace of the CHB-MIT and TUSZ scalp EEG seizure datasets was extracted using transfer component analysis, based on a reproducing kernel Hilbert space approach. We then used the Azimuthal Equidistant Projection to transform 3D electrode coordinates into 2D space, followed by interpolation using the Clough-Tocher technique to generate 16x16 rasters. We thereafter generated feature vectors, each of which was a sequence of 17 ten-layer 16x16 raster arrays. The vectors were used to train a recurrent-convolutional neural network. The network had a 128-unit long short-term memory layer with inputs from 17 parallel networks each with three stacks of convolutional layers. Testing was based on a private 26-subject dataset, combined with randomly selected subsets of the CHB-MIT and TUSZ datasets. A combined sensitivity of 74.5% was achieved, along with a false positive per hour rate of 0.84, and a latency of 2.32 s. Detection sensitivity on the private dataset was 72.5%. These results compare favorably with results of large-scale validation studies in literature and confirm the viability of this approach to increasing the size of training datasets for ESDs.

Cognitive assessment in patients with epilepsy using the Community Screening Interview for Dementia.

OBJECTIVE: Epilepsy is the most common neurological disease worldwide. It may be complicated by cognitive impairments with consequent deleterious effects on education, vocation, and social and family life of affected individuals. We assessed the cognitive functions of Nigerian patients with epilepsy using the modified Community Screening Interview for Dementia (CSID) questionnaire. METHODS: Eighty-two subjects (41 patients with epilepsy and 41 normal controls) participated in the study. The CSID was used to assess language, memory, orientation, attention, calculation, and praxis. The SPSS statistical package was used for data analysis. RESULTS: The mean ages (in years) of patients with epilepsy and controls were 28.32+/-9.22 and 25.98+/-7.72, respectively. The patients with epilepsy performed poorly when compared with the controls (P<0.05) in the domains Language, Memory, Attention and Calculation, and Praxis, whereas there was no statistically significant difference between the patients and controls in Orientation scores. Duration of epilepsy and of antiepileptic drug (AED) therapy had a significant negative impact on all domains of the CSID (P<0.05), whereas type of AED used did not. The CSID had a sensitivity of 91.7%. CONCLUSION: This study showed that patients with epilepsy have significant cognitive impairments compared with controls, and duration of epilepsy and AED therapy have deleterious effects on their cognitive performance. In addition, the CSID has acceptable sensitivity and predictive value. It is recommended that cognitive function assessment should be an integral part of routine evaluation of patients with epilepsy.

Stroke-like syndrome in a middle aged Nigerian woman with metastatic brain cancer.

BACKGROUND: Metastatic brain cancer constitutes about 24 to 25 % of brain tumours worldwide and in Nigeria it constitutes about 40% of brain tumors. The clinical presentation of metastatic tumors may be atypical. OBJECTIVE: To present a middle aged Nigerian woman with a metastatic brain cancer who had a stroke-like syndrome. METHODS: The patient was a 47-year old woman who presented with a two-week history of progressive weakness of the right upper and lower limbs, associated with headache, blurring of vision and slurring of speech. There was a history of weight loss but no history of cough or evening pyrexia. She was not a known hypertensive or diabetic patient though, there were positive history of diabetes mellitus in her father and elder senior brother. Her other systemic review and past medical history were not contributory. RESULTS: Examination revealed a woman with expressive dysphasia and right spastic hemiparesis. Her pulse, blood pressure and heart sounds were normal. There was no carotid bruit. Imaging studies showed metastases in the brain, liver, chest, cervical lymph nodes and bone marrow. Cervical lymph node histology showed metastatic adenocarcinoma. She was managed with chemotherapy, steroids and other supportive therapy but she died on the 40th day of admission due to disease progression and aspiration pneumonitis. CONCLUSION: Metastatic brain cancer may manifest atypically. Physicians should screen any patient with stroke without any apparent risk factors for possibilities of underlying metastatic brain cancer.

Intellectual impairment in patients with epilepsy in Ile-Ife, Nigeria.

INTRODUCTION: Epilepsy is the most common non-infectious neurologic disease in developing countries such as Africa, including Nigeria. This study was designed to assess the intellectual performance of patients with epilepsy (PWE) in Nigeria hoping that the result will serve as the basis for educational, vocational, and social counseling. METHODS: Forty-one PWE were studied along with 41 age-, sex- and education-matched healthy controls. A questionnaire was developed and applied to all subjects and history was taken from patients and eyewitness. The intellectual function of each subject was assessed with the aid of Wechsler Adult Intelligence Scale adapted for Nigerians. All patients subsequently had electroencephalography (EEG) performed and the EEG findings were noted. SPSS statistical package was used to analyze the data. RESULT: The PWE performed poorly on the verbal IQ, performance IQ, and full scale IQ scores when compared with controls (P < 0.05) and 20% of PWE had mental retardation. Long duration of epilepsy, long duration of antiepileptic drug therapy, younger age at onset of epilepsy, increased frequency of seizures, and low educational status were found to have negative impacts on intellectual performance in PWE (P < 0.05) while seizure types and type of antiepileptic drugs (carbamazepine or phenytoin) did not influence intellectual performance. CONCLUSION: This study shows that PWE had significant intellectual impairment when compared with controls. In addition, long duration of epilepsy, long duration of AED therapy, earlier age of onset, increased seizure frequency, and low educational status had a negative impact on intellectual functioning in PWE.

Clinically diagnosed Guillain-Barre syndrome in Ile-Ife, Nigeria.

BACKGROUND: Guillain Barre Syndrome (GBS) is a neurological disorder that poses a great challenge to medical care. It affects all age groups, gender and socio-economic groups. OBJECTIVE: To determine the pattern of clinical presentation as well as the factors that determine morbidity and mortality in Guillain Barre Syndrome (GBS) patients. METHODS: The case records of all the patients with diagnosis of GBS from 1988-2005 were retrieved. Socio-demographic, clinical data and laboratory investigations were collated. RESULTS: There were a total of 14 patients managed during this period, which comprised seven males and seven females. The mean(SD) age was 23.6 (13.3) years. Nine (64.3%) patients were students, only one (8%) patient was a professional and the rest 4 (36%) were artisans. Five (36%) patients presented with weakness of both upper and lower limbs while another five (36%) patients presented with weakness of the lower limbs only and four (28%) patients had bulbar symptoms in addition to weakness of the upper and lower limbs. The most common prodromal symptoms were headache, fever and joint pains. The common symptoms at presentation were excessive sweating paraesthesia (43%), urinary hesitancy and retention (35%). Physical findings include Flaccid quadriparesis 13 (93%), autonomic dysfunction 9 (64.3%), sensory impairment (71.4%) and cranial neuropathies 6 (43.5%). Albuminocytological dissociation was present in the cerebrospinal fluid of five (56%) of nine patients who had lumbar puncture done and erythrocyte sedimentation rate (ESR) was elevated in five patients (38%). The sex, age presenting complaints and treatment given were found not to have correlation with clinical outcome. The pattern of motor paresis and the nature of discharge patient had were significantly correlated with clinical outcome. CONCLUSION: Guillain Barre syndrome present impotant challenge to medical care in Nigeria and it is hoped that this study would sensitize clinicians to the clinical burden of Guillain Barre syndrome among Nigerians.

Stroke mortality in a teaching hospital in South Western Nigeria.

Stroke, a major cause of morbidity and mortality, is on the increase and with increasing mortality. Our retrospective review of all stroke admissions from 1990-2000 show that cerebrovascular disease accounted for 3.6% (293/8144) of all medical admissions; it has a case fatality rate of 45% with the majority (61%) occurring in the first week; the mean age of stroke deaths was 62 years (standard deviation+/-13); and severe as well as uncontrolled hypertension is the most important risk factor. Community-based programmes aimed at early detection and treatment of hypertension, in addition to screening for those with high risk factors, should be put in place.

Pattern and outcome of adult tetanus in Ile-Ife, Nigeria.

OBJECTIVE: This is a retrospective study of all adult patients with tetanus managed at the Obafemi Awolowo University Teaching Hospitals Complex from 1995-2004. The aim was to study the pattern of adult tetanus in Ile-Ife, Nigeria, and see what improvements could be made in the future in particular with regard to decreasing the prevalence in our environment. METHOD: Data was obtained from the hospital records of all the patients, the admission and discharge registers of the medical wards of the hospital. RESULT: 79 adult patients with tetanus were managed during the study period and they accounted for 44% of neurological admissions. There were 56 males and 23 females giving a M:F ratio of 2.4 to 1. 45 (57%) of the patients were under 30 yrs of age and two-thirds (67%) had puncture wounds in the lower limbs. 20 patients (25%) had mild tetanus, 16 (20%) had moderate disease and 43 (55%) had severe tetanus. The patients were treated with tetanus antitoxin, antibiotics and sedatives. The mortality rate was 45% and laryngeal spasm was the most common cause of death. None of the patients was managed in the intensive care unit (ICU). CONCLUSION: Tetanus remains a major public health problem in Nigeria. It is commonly associated with high mortality due to late presentation. Health education should be promoted to reduce the unacceptable prevalence in our practice setting.

Cognitive functions in newly diagnosed patients with HIV infection in a tertiary health facility: Assessment using community screening interview for dementia.

INTRODUCTION: Neurocognitive dysfunction is a detrimental complication of HIV infection. In this study we attempt to characterize the pattern of cognitive dysfunction in a sample of Nigerian patients with newly diagnosed HIV infection. METHODS: We conducted a prospective study in which 50 patients with newly diagnosed HIV infection were studied along with 50 normal control subjects. The participants were evaluated with the medical history, general, physical and neurological examination. Laboratory evaluation and chest X-Ray were done for all patients. The Community Screening Interview for Dementia (CSID) questionnaire was administered to all the study participants. RESULTS: About 70% of the patients were in advanced disease stage. The mean age (SD) of the patients and controls in years were 36.44 ± 8.22 and 35.40 ± 11.53 respectively. More than half (56%) of the patients had secondary level of education (12 years of education). About 20% of the patients had severe neurocognitive impairment while 48% had minor neurocognitive disorder. The patients with HIV infection performed poorly in the domains of language, memory, orientation, attention/calculation and praxis relative to controls (p < 0.05).There were no significant effect of gender, age, sex and level of education on cognitive functions in the patients (p > 0.05) but the presence of opportunistic infections had negative impact on the performances on orientation and total CSID scores in the patients with HIV infection (p < 0.05). CONCLUSION: Patients with newly diagnosed HIV infection have poor cognitive functions when compared to normal controls and some presence of opportunistic infections in the patient is a significant risk factor for cognitive impairment.

Emotional distress and self-reported quality of life among primary caregivers of stroke survivors in Nigeria.

OBJECTIVES: To investigate emotional symptoms and domain quality of life (QOL) among primary caregivers of stroke survivors and to determine survivor-related and caregiver-related predictors of these variables. DESIGN: A cross-sectional study. SETTING: Medical units of the two major hospitals of the Obafemi Awolowo University Teaching Hospitals Complex, ile-Ife, Nigeria. SUBJECTS: One hundred and three matched-pairs of caregivers of stroke survivors and caregivers of mild hypertensive patients, and 103 stroke survivors. RESULTS: Twenty three (22.3%) and 25(24.3%) stroke caregivers were observed with clinically significant anxiety and depressive symptoms respectively compared with 12(11.7%) and 14(13.6%) subjects in the control group. Stroke caregivers were observed with significantly higher mean anxiety and depressions scores, and also, with significantly lower mean scores on the four QOL domains (physical health, psychological health, social relationships and environment). By multiple linear regression analysis, anxiety symptoms in stroke caregivers were predicted by high socioeconomic status of survivors and paresis in them. Depressive symptoms were predicted by high caregivers' age and depression in the patients. Higher QOL on one or more WHOQOL-Bref domains was predicted by intimate relationship with survivor, female gender of caregiver, longer duration of caring, higher education of survivor and higher age of survivor. Low QOL on one or more domain(s) was predicted by higher caregivers' age, carers' perception of survivor as cooperative, female gender of survivor, depression in survivor, paresis and cognitive impairment in survivor. CONCLUSION: Caregiving imposes high burden on stroke carers. Attention should be paid to their psychological needs and services should be designed for them to ameliorate the burden.
