Use of indigenous language for clinical clerkship: a cross-sectional survey in Nigeria.

Background: Doctors' knowledge of the native language of their patients is important to effectively communicate with them. Aims: This paper aimed to explore the views and practices of medical students in Nigeria on the use of Yorùbá (an indigenous language) in their clinical clerkship. Methods: This was a cross-sectional survey of students in two medical colleges in Ekiti State, Nigeria. Data were collected using self-administered questionnaires. Results: The study included 312 medical students, 176 males and 136 females. Most students (70.8%) used Yorùbá in their clinical clerkship despite learning medicine in English. Only 16.0% of the students relied on interpreters. None of the students had had exposure to language training in the course of their medical education. Most of the students (73.7%) supported the incorporation of indigenous language training into the medical school curriculum, and agreed that teaching indigenous languages in medical school would enhance communication skills. Conclusions: Incorporation of indigenous language training into the medical school curriculum in Nigeria is recommended to help overcome language barriers in clinical practice.

Aetiologies of profound bilateral sensorineural hearing loss among children in Ekiti State, South Western Nigeria.

INTRODUCTION: a strong need exists for the knowledge of aetiologies of diseases as this will guide the clinicians on the strategies for their treatment and prevention. In this study, we determined the aetiologies of profound bilateral sensorineural hearing loss (pbSNHL) with a view to provide the relevant data needed for preventive and therapeutic intervention among children in Ekiti State, South Western Nigeria. METHODS: medical records of children with pbSNHL seen over a ten-year period were analysed. RESULTS: in all, records of 142 children with pbSNHL were analysed. The results showed spectrum of aetiologies that were similar to those reported decades ago with the 'unknown' assuming a recurring decimal. Of the known (acquired) cases, measles takes up the largest 'chunk' with a prevalence of 45.8%. Twenty-eight (32.2%) of those with febrile illnesses had treated their fever with ototoxic antibiotics. Late diagnosis was characteristic of the pbSNHL. CONCLUSION: this study shows that there hasn't been any significant shift in the common causes of pbSNHL. Of great concern is the persistence of the 'unknown' causes which assumes a recurring decimal in this and previous studies. Also worrisome is the high prevalence of measles-induced pbSNHL despite the availability of anti-measles vaccine. We therefore suggest effective immunization against measles and other vaccine-preventable causes of pbSNHL. The need for intensive research on the unknown causes of pbSNHL is hereby stressed. Also recommended is routine hearing assessment for survivors of febrile conditions so as to detect, if any, hearing loss promptly.

Perceptions and Practice of Early Diagnosis of Sickle Cell Disease by Parents and Physicians in a Southwestern State of Nigeria.

BACKGROUND: Early sickle cell disease (SCD) diagnosis has shown promise in combating SCD in many countries. The aim of this study was to assess the practice and perception of early SCD diagnosis among a group of parents and physicians in Nigeria. Patients and Methods. This was a cross-sectional descriptive study conducted to assess the opinions and practice of early diagnosis of SCD among 135 physicians caring for SCD patients and 164 mothers of children with SCD in a southwestern state of Nigeria. RESULTS: Most physicians 132 (97.8%) were aware of prenatal SCD diagnosis, but only 51 (37.8%) would recommend it. Most physicians 129 (95.6%) routinely recommend premarital SCD genetic counseling and testing, and 89 (65.1%) were aware of the national government newborn screening program but lesser proportion 75 (55.6%) were willing to recommend it. Amongst the mothers, 154 (94%) and 158 (96%) had encountered genetic counseling for SCD and were willing to offer newborn screening to their children, respectively. On the contrary, fewer mothers 42 (25%) were aware of prenatal SCD diagnosis, 28 (17%) were willing to partake in it, and 44 (26%) were undecided. There were discrepancies in the willingness by physicians to practice early SCD diagnosis and its uptake by mothers (p < 0.0001). The commonest reason given by both the physicians and mothers for not practicing SCD prenatal diagnosis was the high cost of the procedure. CONCLUSION: The perceptions and practice of early SCD diagnosis was suboptimal in the study locality. Scaling up awareness and universal coverage are required.

Clinicoepidemiology of benign paroxysmal positional vertigo in Nigerian.

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is poorly reported in developing countries. This study aimed at determining the prevalence, aetiology, and comorbid illnesses of benign paroxysmal positional vertigo in our center. MATERIALS AND METHODS: This was a prevalence hospital-based study of all patients with the diagnosis of benign paroxysmal positional vertigo (BPPV). Pretested interviewer assisted questionnaire was administered to obtain data. Otoscopic examination, otoneurologic review, followed by mandatory Dix Hallpike maneuver and supine roll test was performed on all patients to diagnose posterior, lateral or anterior canal benign paroxysmal positional vertigo. All the data obtained were collated and analyzed by using SPSS version 16.0. RESULTS: Prevalence was 1.9%. Peak prevalence of 37.0% was at age group 41-50 years. Male accounted for 46.1% with male to female ratio of 1:1.2. Benign paroxysmal positional vertigo accounted for 62.3% urban dwellers, 33.1% postsecondary education, 39.6% Civil servant and 33.8% married. There were 99.4% unilateral and 64.3% right benign paroxysmal positional vertigo. Idiopathic was 70.1% while trauma, migraine, and inner ear disorder were 20.8%, 7.1%, and 1.9%, respectively. Benign paroxysmal positional vertigo was 66.2% posterior semicircular canal followed by 24.7% lateral semicircular canal and 0.6% anterior semicircular canal. Commonly associated comorbid illnesses were visual disorder, hypertension, arthritis, and diabetes mellitus in 27.9%, 23.4%, 22.1%, and 2.6%, respectively. CONCLUSION: Benign paroxysmal positional vertigo is common otologic disorder. It is associated with significant comorbid illnesses. Early detection will reduce morbidity and mortality. Improvement in the level of health care at primary level and health education to create awareness among the populace is to be encouraged.

Crash Characteristics and Pattern of Motorcycle Related Facial Bone Fractures in a Sub-Urban Nigerian Teaching Hospital.

CONTEXT: Recent studies indicated that significant proportion of facial fractures attributed to road traffic mishaps in the middle- and low-income countries are caused by motorcycle (MC) crashes. However, there is limited information on crash characteristics of such injuries. This study was designed to examine the crash characteristics, pattern of fracture, and sociodemographics of patients with facial bone fractures due to MC crashes in our institution. SUBJECTS AND METHODS: Data on patients' sociodemographics, pattern of presentation, type(s) of fracture, patient status, crash characteristics, level of consciousness, and treatment offered were collected and analyzed. RESULTS: A total of 151 patients, aged 7-59 years were reviewed during the study period. A male preponderance was observed (M:F = 4:1) and the patients were predominantly motorcyclists (64.8%, n = 98). The most common mechanism of crash was collision with another MC (51.6%, n = 78). A total of 194 fractures were reviewed and the mandible (58.8%, n = 114) was more commonly affected than the midface (41.2%, n = 80). The predominant site on the mandible was the body (31.6%) while zygoma (32.5%) was the most affected part of the midface. Patient status was found to have a statistically significant relationship with loss of consciousness (P = 0.02). Eighty-two fracture sites (42.3%) were managed with open reduction and internal fixation. CONCLUSIONS: Facial bone fractures occur in a significant proportion of MC crashes and riders are predominantly affected. In addition, a larger proportion of commuters rarely wear crash helmet which could have offered protection. Continual advocacy on preventive measures and enforcement of road safety regulations is hereby advised.

Otological burdens of Nigerian children with sickle cell disease.

INTRODUCTION/OBJECTIVE: Sickle cell disease (SCD) is associated with episodic illnesses, multi-systemic affectations and end-organs damages. Otolaryngological related complications are not unexpected. Studies on the overall Otolaryngological pathologies in children with SCD relative to their non-SCD counterparts are scanty in Nigeria. We hypothesized that children with SCD are likely to have more otological burdens than their non-SCD counterparts. Thus, we embarked on this study to describe and compare the overall ear diseases burdens seen in children with sickle cell disease relative to their non-SCD counterparts. METHODOLOGY: A cross-sectional study of otologic diseases among children with SCD and their non-SCD counterparts attending the paediatrics and otolaryngological clinics of a Nigerian tertiary institution was conducted. RESULTS: Overall, 80 (47.62%) of the 168 ears of SCD patients compared to 37 (22.02%) of the 168 ears of their non-SCD counterparts were affected by diseases (p < 0.0001). The diseases were Wax, Otitis Media with Effusion, Suppurative Otitis Media, Otosclerosis and Sensorineural Hearing Loss (SNHL). There was a significant difference in the prevalence of SNHL and solitary otosclerosis between the SCD patients and their non-SCD counterparts (P < 0.05) respectively. Both the Haemoglobin concentration and HbF did not discriminate between the SCD participants with or without SNHL (P > 0.05). CONCLUSION: This study showed that otological burdens are more prevalent in children with SCD than the non-SCD population. The microbiological peculiarity of suppurative otitis media (SOM) among participants stresses the need for concerted efforts at preventing SOM in SCD children. There is need for special Otolaryngological care for SCD children.

Banji's test: A new diagnostic test of ear wax impaction.

BACKGROUND: Impaction is a major clinical criterion for the treatment of ear wax. In this paper, a new diagnostic test of ear wax impaction is described with a view to improve the diagnostic accuracy of ear wax impaction. METHODS: Patients with or without impaction of their ear wax were examined with the Banji's test. The test consists of a pull on the pinna and a response to sound perception. A sudden, momentary increase in sound perception following the pull is considered positive and indicates impaction. A negative response is when there is no increase in sound perception and is non-specific. RESULTS: In all, 165 patients aged 10 to 43 years were studied. Of this, 60 (36.4%) had bilateral while 105 (63.6%) had unilateral ear wax, giving a total of 225 ears with the condition. Of the 225 ears, 132 had impaction while 93 had no impaction. Banji's test was positive in 121 and negative in 11 ears with impaction, while it was positive in 12 and negative in 81 ears without impaction. This gives a sensitivity of 91.7% and specificity of 87.1%. There was a strong correlation between the Banji's test and clinical criteria for impaction. CONCLUSION: With a sensitivity of 91.7%, Banji's test can accurately diagnose ear wax impaction. A positive test is predictive that removal of the ear wax will significantly relieve the patient of auditory symptoms. The test is simple, harmless, and can discriminate between wax and other causes of otological symptoms.

Factors Influencing the Academic Performance of Children with Sickle Cell Anaemia in Ekiti, South West Nigeria.

Background: There is a paucity of information on factors that influence the school performance of children with sickle cell anaemia (SCA) in Nigeria, despite her huge burden of the disease. Methods: In total, 101 children with SCA were recruited at a paediatric clinic in Nigeria. Their socio-demographic-matched classmates were the controls. Academic performance and cognitive functioning were obtained from school reports and Ziler's Draw-a-Person Test, respectively. Factors influencing the academic performance were determined. Results: Children with SCA had higher rates of school absence and lower haemoglobin concentration (p < 0.05). There was no difference in overall school performance between children with SCA and controls (59.0 vs. 60.6%; p = 0.256). School absenteeism > 1 week independently predicts poor school performance among the study participants (odds ratio = 15.71; 95% confidence interval = 5.93-41.66; p =0.000). Most SCA children with poor performance were absent from school for > 1 week. Conclusion: There is need to address causes of school absenteeism among children with SCA.

Trends and complications of ear piercing among selected Nigerian population.

BACKGROUND: The reported health and socioeconomic consequences of ear piercing, especially in modern day society, underscore the need to further research into this subject. In this study, we determine the trends and complications of ear piercing among selected Nigerian population. AIM AND OBJECTIVES: The aim and objective of this study was to draw attention to the trends and complications of ear piercing with a view to prevent its associated complications. METHODOLOGY: It is a descriptive cross-sectional study carried out between February and May 2015 among selected Nigerian population from two of its six geo-political zones. A self-administered semi-structured questionnaire which had been pretested was used to collect data from 458 respondents who consented using multistage sampling technique. RESULTS: Of 480 respondents enumerated, 458 completed the questionnaires and gave their biodata. The male:female ratio was 1:6.2. Their ages ranged from 18 to 75 years with a mean of 35.56 ± 10.16. About 35.4% of the respondents were within the age group of 31-40 years. Majority of the respondents, i.e.,79.3% practiced ear piercing on their children. Most of them (86.8%) preferred single piercing. Ear piercing was performed within the 1st week of birth in 37.2% of the respondents. Large percentage (93.2%) of the respondents will not encourage ear piercing in male children. Nearly 20.5% of the respondents observed complications. CONCLUSION: Ear piercing remained a common practice in Nigeria, with respondents preferring it on females. Majority of the piercings are done in childhood and by untrained personnel. Keloid formation was the notable complication observed by the respondents. There is a need to increase awareness about the hazards of ear piercings and to enact laws that regulate ear piercings particularly in children which is hereby stretched.

Aural foreign body extraction in children: a double-edged sword.

INTRODUCTION: Foreign body insertion into the ear in children is common world-wide. The goal of this work is to describe the procedural complications of aural foreign body extraction in children. METHODS: A retrospective analysis of records of children with aural foreign bodies was conducted. Patients' bio data, type of foreign bodies, referrals, techniques of removal and complications were extracted from the case files. The foreign bodies were categorized into graspable and non-graspable objects. Patients with complications caused directly by the foreign body were excluded. RESULTS: There were 136 cases. Eighty-seven (64.0%) were males while forty-nine (36.0%) were females. Their age range from 5 days to 16 years with 109 (80.2%) aged below 8 years. Eighty-nine (65.4%) and 47 (34.6%) cases were treated by otolaryngologists and non-otolaryngologists with a complication rate of 15.7% and 68.1% respectively. One case suffered severe hearing loss following complicated attempt at removing foreign body in the only hearing ear. Overall, the complication rate was higher (44.4%) with removal of non-graspable than (28.6%) with graspable objects. CONCLUSION: Procedural complication is an ever-present hazard of aural foreign body extraction in children. Its occurrence can be prevented or largely reduced if health care-givers know their limitation based on their clinical skills and acquaint themselves with established criteria for referral. As a rule, we suggest that, foreign body in the only hearing ear and failed attempted first removal should be considered criteria for otolaryngologic referral.

Earwax Impaction: Symptoms, Predisposing Factors and Perception among Nigerians.

BACKGROUND AND AIM: Earwax impaction is a common ear disorder with presentation worldwide. This study aimed at determining the clinical presentation, patients' perception of earwax, and its predisposing factors among Nigerians. MATERIALS AND METHODS: This prospective study was conducted on consented patients with diagnosis of earwax impaction at the Ear, Nose, and Throat Clinic of the University Teaching Hospital, Ado Ekiti, Ekiti state, south west, Nigeria. The research was carried out over a period of one year (April 2008 and March 2009). All consented patients were told about the aim and scope of the study and their biodata were taken. Detailed history of the presenting complaints and otological complaints were taken and all data entered into structured questionnaires. Full-ear examination and otoscopy were performed and our findings were documented. From all these exercise, data obtained were collated and statistically analyzed. RESULTS: A total of 437 patients were diagnosed with earwax impaction and prevalence of 20.1% was found. There was 52.2% male preponderance with male to female ratio of 1:1. Bimodal peak age distribution of patients was found at the extreme ages of life. Most common sources of our patients referrals were 39.6% general medical practitioners with least from 6.2% self-reporting. Common presentations were 277 (63.3%) hearing loss, 268 (61.3%) earache (otalgia), and 234 (53.5%) tiinitus. Unilateral earwax impaction, 75.1% was more common than bilateral earwax impaction. Right ear was more affected than left ear. Recurrent earwax impaction of 66.1% was found in our study. About 382 (87.4%) believed earwax was due to dirt or dust. Most common predisposing factors among our patients were self-ear cleaning. CONCLUSION: Common predisposing factor of this high recurrent earwax impaction were wrong perception and preventable self-ear cleaning with indiscriminate objects including cotton tip swab. This condition could be reduced by health education of the community.
