Clinical Utility of Procalcitonin and C-Reactive Protein in the Management of Neonatal Sepsis in a Resource-Limited Nigerian Hospital.

BACKGROUND: Neonatal sepsis is an invasive infection of the bloodstream in neonates and a leading cause of morbidity and mortality among them. AIM: To investigate the role of procalcitonin (PCT) and C-reactive protein (CRP) in the management of neonatal sepsis. MATERIALS AND METHODS: This was a prospective case-control study over one-year period using convenience sampling. Blood samples for PCT and CRP were taken from all neonates, while blood culture and white blood cell count samples were additionally taken from babies with neonatal sepsis. PCT and CRP were repeated at 24 and 48 hours. The continuous variables were found to have a nonparametric distribution. They were presented as median and interquartile range, and compared using Wilcoxon signed rank and Friedman test as appropriate. RESULTS: The blood culture analysis yielded a prevalence of 12.7% with Staphylococcus aureus being the commonest organism. Baseline concentrations of PCT (1.28 ng/ml) and CRP (17.31 mg/L) in neonates with sepsis were higher than that of controls (PCT-0.63 ng/ml, CRP-5.40 mg/L). PCT concentrations decreased after two days of antibiotic treatment, while CRP concentrations decreased after a day. The concentration of both decreased to normal levels after two days of treatment. CONCLUSION: This study showed that CRP was more reliable in monitoring antibiotic therapy, unlike other studies which suggested PCT. In cases where the management of neonatal sepsis may be limited by a low blood culture yield, therapeutic monitoring may be aided by CRP and/or PCT.

Pattern and awareness of complementary and alternative medicine usage for otorhinolaryngological problems among residents in Ekiti State.

Background: The use of complementary and alternative medicine (CAM) in the treatment of various ailments globally has called for more research. Aim: This study aimed to draw the attention of the stakeholders to the prevalence, pattern and awareness of CAM usage in otorhinolaryngological ailments and the need to safeguard the health of CAM users in Ekiti state, south - west Nigeria. Patients and Methods: This is a cross sectional descriptive study carried out over a 12-month period (January to December, 2019) among consented patients that attended ear, nose, and Throat (ENT) clinics in two tertiary health institutions in Ekiti state. All the participants are aged 18 years and above. A self-administered semi structured questionnaire was used to collect data from our respondents. Results: A total of 148 respondents were analyzed comprising of 56 (37.8%) males and 92 (62.2%) females given a male to female ratio of 1:1.6. Their age ranged from 20-79 years with a mean of 48.03 ± 15.11 SD. The highest response was in the age group 40-49 years representing 30.4% of the respondents. About half (51.4%) of our respondents were aware of the use of CAM for throat-related conditions. Few of the respondents (18.9%) are currently using CAM. About 33.1% of our respondents were satisfied with CAM. Only 4 (2.7%) of them experienced side effects to the use of CAM. For ear-related problems, Anointing/Olive (Olea europaea) oil was most commonly used in 34.5% of our respondents; Effinrin (Ocimum gratissimum), a local herb was commonly used in 29.7% for nose and local gin in 37.2% of our respondents for throat problems. Majority of them 44 (29.7%) got information about the various agents used through Vendors/traditional health practitioner. Conclusion: This study showed that the prevalent of CAM usage in ORL is quite low in our setting, which represent about one-fifth of the respondents. Although respondents claimed that the system was efficacious, awareness to its usage was very low and there was no evidence to prove that the diagnosis were known before using CAM. The use of Orthodox method in treating Otorhinolaryngological ailments is still the best. We therefore recommend empirical studies on CAM in future.

Performance of the Lea symbols chart for screening Nigerian children aged 3 to 5 years.

BACKGROUND: Vision screening in children of preschool age (age 3-5 years) gives the opportunity for timely detection of amblyopia. The tools that would be used for screening must have high rates of testability in these young children, and must have high enough sensitivity and specificity to be reliable and cost effective. AIMS: To assess the performance of the Lea symbols chart as a screening tool in children aged 3 to 5 years attending primary schools in Kwara State, Nigeria. METHODS: Visual acuity (VA) of 464 children selected from 12 schools by a multistage sampling procedure was checked using the Lea symbols chart by trained Lea screeners. Children meeting the referral criteria and untestable children had a comprehensive eye examination. Testability rates, sensitivity, specificity, positive, and negative predictive values were analyzed based on age and gender, with corresponding significance values generated. RESULTS: Testability rates among 5 year olds were as high as 99.1%, decreasing significantly to 95.5% in 4 year olds and 85.7% in 3 year olds (p value < 0.001). Visual acuity performance improved with age (p value 0.002) but was unrelated to gender. The Lea symbols chart had an overall specificity of 77.4% (63.2% among 3 year olds and 83.5% among 5 year olds). At VA thresholds of 6/12 for 5 year olds and 6/15 for 3-4 year olds, the screening tool became 87.7% specific among 3 year olds and 94.3% specific among 5 year olds (overall 92.5%). CONCLUSION: The Lea symbols chart was found to be a useful screening tool in this environment, especially among 5 year olds. The reduced specificity among 3-4 year olds may prompt further research into the appropriate VA thresholds for 3-4 year olds to reduce the burden of unnecessary comprehensive eye evaluations resulting from too many false positive results.

MODIC CHANGES IN ADULTS WITH CHRONIC LOW BACK PAIN IN NORTH CENTRAL NIGERIA.

BACKGROUND: Modic changes in the endplates of the vertebral bodies have been associated with low back pain. There is however paucity of information on the pattern of Modic changes in the lumbosacral spine in Nigerians with low back pain. AIM: To determine the prevalence of Modic changes in patients with chronic low back pain in our environment. DESIGN OF STUDY: Cross-sectional longitudinal study. SETTINGS: University of Ilorin Teaching Hospital, Ilorin, Nigeria. METHODOLOGY: A total of 147 consecutive adults who had MRI of the lumbosacral spine for chronic low back pain were examined for the presence of Modic changes. RESULTS: 35(23.8%) individuals had Modic changes present out of I47 patients with low back pain evaluated.Out of the 735 lumbar vertebral endplates evaluated, 90(12.2%) had Modic changes present. Among the endplates with Modic changes, 36(40%) were type I, been the most common in our sample, while 27(30%) were type II and type III each. CONCLUSION: This study has shown that Modic changes occurred more frequently at the end plates of lower lumbar vertebrae(L4/L5, and L5/S1) and Type I was the most common while Type II and III had equal prevalence; the changes occurred more frequently with increasing age suggesting these changes are degenerative in nature.
