Background: Brain abscess in children is a neurosurgical emergency with potentially catastrophic outcome despite the advances made in neuroimaging techniques and antibiotic therapy. Symptoms are nonspecific and may vary with the child's age, location, size, numbers and stage of abscess, and the primary source of infection. Treatment is usually with broad-spectrum antibiotics in combination and surgical evacuation in most cases or antibiotics alone in selected cases with clear-cut indications. This study was to document clinical characteristics, etiological factors, and spectrum of bacteriologic agents responsible for pediatric brain abscess in an African city, the challenges and management outcome over the study period., Methods: This was a retrospective study over an 11-year period involving 89 children who presented with brain abscess. Information of interest was extracted from the medical records of each participant. The results from data analysis were presented in charts and tables., Results: Eighty-nine children aged 0.85-15.7 years (median age of 6.4 years) met the inclusion criteria. The male-to-female ratio was 1.8:1. Headache (80%), fever (78%), and hemiparesis (78%) were the most common symptoms. Brain imaging deployed was CT scan in 56 (63%), MRI in 9 (10%), and transfontanel ultrasound scan in 24 (27%) children. Seventy-one (80%) children had antibiotics with surgical evacuation while 18 (20%) children received only antibiotics. In 19 (27%) children, the culture of the abscess was negative. In 53 (75%) children, Gram-positive aerobic organisms were isolated. A total of 75 patients (84%) had a favorable outcome., Conclusion: Pediatric brain abscess still poses significant public health challenge, especially in resource-limited regions. Successful management of brain abscess requires high index of suspicion for early diagnosis, referral, and intervention., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Surgical Neurology International.)

Background: Diabetic foot ulcer is an associated and an increasing problem among individuals with diabetes. The aim of the present study was to evaluate the risk factors for amputation in patients with diabetic foot ulcer as well as common causes of increasing mortality in these patients., Methods: The design was an observational prospective study carried out between July 2015 and June 2018. The Demographic data of all patients with diabetic foot ulcer seen at Lagos University Teaching Hospital and Nigerian Navy Reference Hospital Lagos with their clinical signs and symptoms as well as basic laboratory results were documented. The ankle brachial index (ABI), history of neuropathy, nephropathy and the relationship between these and lower limb amputation and mortality were collected and analyzed., Results: There were 539 patients with diabetic foot ulcer seen during the 3-year period. The mean age was 62 + 13.7. There was male preponderance with a ratio of 1.7:1. Patient with amputation more often had ABI <0.9. Male sex is a risk factor for amputation. Over 40.5% of the patients had grade I ulcer, 19.5% had grade II, while 22.3%, 12.3% and 5.4% had grade III, IV and V respectively. Amputations were performed in 144(26.7%) patients (48 minor, 96 major). Compared with patients without amputation, patients with amputation differed significantly concerning diabetes and its complications. Mortality rate was 11.8%., Competing Interests: The Authors declare that no competing interest exists., (Copyright © 2021 by West African Journal of Medicine.)

Background: Halitosis is a common medico social symptom among children., Aim: To determine the clinical, epidemiological patterns, aetiology and psycho-social issues of halitosis among children in a tertiary hospital in Nigeria., Methodology: This was a prospective hospital based study of children with complaints of halitosis. The study was carried out in Ear, Nose & throat Department, Ekiti State University Teaching Hospital, Ado Ekiti over a period of two years, (October 2015 to September 2017). Consent was obtained from the parents/guardian. Data was obtained by using pretested interviewer assisted questionnaire.All the data obtained were collated and analyzed by using SPSS version 16.0. Ethical clearance was obtained from the ethical committee of the institution., Results: The prevalence of halitosis in this study was 6.8% and there were 58.5% males and 41.5% females with a male to female ratio of 1.5:1. Their age ranged from 1 year - 18 years with a mean of 9.48 ± 5.84 SD years.Sources of referral for the otorhinolaryngology, head and neck care were mainly from general practitioners (52.3%) and from pediatricians (24.6%). Halitosis was noticed by family members in 50.8% and from family friends in 23.1%. Nasal and throat diseases in 49.2% and 29.2% respectively were the commonest otorhinolaryngology, head and neck disorders that were responsible for halitosis. The major causes were rhinosinusitis in 24.6%, impacted nasal foreign body in 23.1% and adenotonsillar hypertrophy in 18.5%. Associated disabilities in children and family with halitosis include social withdrawal in 35.4%, low social interaction in 32.3% and depression in 29.2%. Acute halitosis (<3/12) accounted for 50.8% while chronic halitosis (>3/12) accounted for 49.2%. In all, fifty four (83.1%) of the patients were successfully treated., Conclusion: Bad breath is a common ear, nose and throat symptom in children it is commonly due to nasal and pharyngeal diseases which are amenable to treatment.

Background: Penetrating anterior neck injuries are potentially life threatening and the causes vary across countries of the world. Studies in Nigeria have been mainly isolated case reports and few retrospective studies., Aim: The aim of this study was to assess the causes, severity and management outcome of patients treated in our centre., Methodology: This is a retrospective study of penetrating anterior neck injuries treated at the Lagos University Teaching Hospital over a 25-year period. The case records were retrieved and demographic data as well as the causes, site, extent of injuries and treatment outcome were analyzed., Results: The mean age of the 39 patients in this study was 30.5yrs ± 7.9 SD with a male: female ratio of 6.8:1. Inflicted cut throat injuries accounted for 46% followed by vehicular accidents in 21%. Zone II site of the neck was the commonest site of injury 61.6% of the patients; while 71.8% of the patients presented within 24hrs of the injury, 46% of them had immediate blood transfusion. Tracheostomy was the main method of securing the airway. Primary soft tissue repair was performed on all the patients. Laryngopharyngeal repair was done in 61.5%. Peri-operative mortality was 7.7% and 83.3% had prolonged hospital admission with wound infection in 27.8% and laryngotracheal stenosis in 22.2% as the commonest complications., Conclusion: This study has shown that penetrating anterior neck injuries is not uncommon in Nigeria and commonly due to cut throat and vehicular accidents. Proper documentation and following established management protocols will improve outcome.

Background: Assessment of clinical skills is essential in medical education. Ideally marks should be based on the student's competence alone. The limitations of the traditional long case examinations such as the patient and examiner variability are well known. The objective structured clinical examination (OSCE) was designed to overcome these limitations. Studies comparing the OSCE and the traditional long case examination in the same group of students are very sparse., Aim: To compare the objective structured clinical examination (OSCE) and the traditional long case examination by determining their correlations with other forms of assessment in undergraduate surgery., Setting: This study was carried out at the College of Medicine, University of Lagos, Nigeria., Methodology: The results of 612 undergraduate students in our medical school of the University of Lagos, Nigeria over a period of 4 years (2012-2015) were analysed. The scores in the long case examination , objective structured clinical examination (OSCE) , multiple choice questions and Essays were analysed and compared using the Pearson's Correlation co-efficient. SPSS version 17 software was used and a P-value < 0.01 was regarded as statistically significant., Results: Overall, there was a statistical significant positive correlation among most forms of assessment. The OSCE and the long case examination had a correlation of 0.374. Compared with the long case examination, the OSCE had a higher correlation with all other forms of assessment. The total clinical score (the sum of all long case examination and OSCE) however performed better than the OSCE or the long case examination alone as it had the highest correlation with all other forms of assessment., Conclusion: The OSCE has been shown to be better than the long case examination as an indicator of the student overall knowledge of surgery as it had a superior correlation with other forms of assessments. The total clinical score was however the best indicator of the student overall knowledge in Surgery as it had the best correlation with other forms of assessment. We recommend and encourage institutions that presently combine the OSCE and the long case examination to carry out similar analysis such as ours to determine the desirability of combining LCE and OSCE rather than outright replacement of LCE with OSCE.

Background: Chronic rhinosinusitis (CRS) significantly lowers the quality of life of patients. The common use of broad spectrum antibiotics for its treatment may alter the pathogens that promote the persistence of this condition. However, the data concerning the distribution of bacteria species. in patients with CRS are not consistent., Objective: To isolate the common aerobic and anaerobic bacteria from the middle meatal aspirates of adult patients with CRS and determine their antibiotic sensitivity patterns Methods: This was a case-control study of adults with diagnosis of CRS. Middle meatal aspirate and swab were obtained from cases and control respectively for bacteriological studies. Data analysis was done using Statistical package for social sciences (SPSS) version 17 Result: Forty one aerobic bacteria were cultured. Sixty one percent of the aerobic bacteria isolated were gram positive (staphlylococcus.aureus was the most frequently found) organisms while the remaining 39% was gram negative. Fifteen peicent of the cultured isolates yielded mixed growth of both aerobes (Gram positive and gram negative).3(6%) isolates of Bacteroides species were cultured Conclusion: The present study found that Staphylococcus aureus, streptococcus pneumoniae, Proteus mirabilis, Klebsiella spp, Escherichia coli and Bacteroides spp) were the common bacterial flora in the paranasal sinuses of patients with CRS.
