Evaluation of Antibiotic Prescription and Utilization amongst Hospitalized Children in a Tertiary Facility in Sokoto, North-Western Nigeria

Background: Antibiotics are the most widely utilized therapeutic agents. Inappropriate use causes increase cost and antibiotic resistance. The World Health Organization recommends assessment of antibiotics use to guide prescribing practices. Objective: To describe the pattern of antibiotic usage among paediatric inpatients aged > 1 month to 15 years in a tertiary hospital in Sokoto, Nigeria. Methods: Febrile children were recruited prospectively by systematic random sampling from January to October 2018. Socio-demographics, diagnosis, antibiotics administered were obtained from case notes. The WHO indicators of use of antibiotics were employed for evaluation. Data was analysed with SPSS version 23. Results: Out of 352 children, 318 (90.3%) received antibiotics; commonest being Ceftriaxone in 155/318 (48.7%), Cefuroxime in 74 (23.2%), and Metronidazole in 29 (9.1%). Average number of antibiotics per patient was 2.3±1.1 with treatment duration of 4.3±1.4days. Antibiotic consumption was 937.2 days of antibiotic therapy/1000 patient days (DOT/PD). Generic name was used in 92.3% while 100% of the drugs were on the essential medicine list. Frequent diagnoses were severe malaria 98/352 (27.8%), respiratory infections 39 (11.1%) and severe malnutrition in 38 (10.8%). Only 6 (1.7%) patients had microbiologic evidence of infection. Conclusion: Utilization of antibiotics is higher than recommended. There is need for improved diagnostic facilities to avoid antibiotic overuse and its consequences.

The impact of bone mineral density and disc degeneration on shear strength and stiffness of the lumbar spine following laminectomy

Purpose Laminectomy is a standard surgical procedure for elderly patients with symptomatic degenerative lumbar stenosis. The procedure aims at decompression of the affected nerves, but it also causes a reduction of spinal shear strength and shear stiffness. The magnitude of this reduction and the influence of bone mineral density (BMD) and disc degeneration are unknown. We studied the influence of laminectomy, BMD, and disc degeneration on shear force to failure (SFF) and shear stiffness (SS). Methods Ten human cadaveric lumbar spines were obtained (mean age 72.1 years, range 53-89 years). Laminectomy was performed either on L2 or L4, equally divided within the group of ten spines. BMD was assessed by dual X-ray absorptiometry (DXA). Low BMD was defined as a BMD value below the median. Intervertebral discs were assessed for degeneration by MRI (Pfirrmann) and scaled in mild and severe degeneration groups. Motion segments L2-L3 and L4-L5 were isolated from each spine. SFF and SS were measured, while loading simultaneously with 1,600 N axial compression. Results Low BMD had a significant negative effect on SFF. In addition, a significant interaction between low BMD and laminectomy was found. In the high BMD group, SFF was 2,482 N (range 1,678-3,284) and decreased to 1,371 N (range 940-1,886) after laminectomy. In the low BMD group, SFF was 1,339 N (range 909-1,628) and decreased to 761 N (range 561-1,221). Disc degeneration did not affect SFF, nor did it interact with laminectomy. Neither low BMD nor the interaction of low BMD and laminectomy did affect SS. Degeneration and its interaction with laminectomy did not significantly affect SS. Conclusions In conclusion, low BMD significantly decreased SFF before and after lumbar laminectomy. Therefore, DXA assessment may be an important asset to preoperative screening. Lumbar disc degeneration did not affect shear properties of lumbar segments before or after laminectomy. © 2012 Springer-Verlag

Glomerular filtration rate in steady state children with sickle cell anaemia in Sokoto, North-Western Nigeria

 Background: Sickle cell anaemia (SCA) affects mostly people of African origin. It causes kidney problems termed Sickle cell nephropathy (SCN). Increased   glomerular filtration rate (GFR) has been documented as one of the functional abnormalities seen in young SCA patients.Objective: To estimate GFR in Nigerian children with SCA in steady state in Usmanu Danfodiyo University Teaching Hospital (UDUTH), SokotoMethodology: All patients were randomly selected in a systematic fashion by choosing alternate patients as they presented at the SCA Clinic if they met the inclusion criteria. The controls were apparently healthy social class-matched haemoglobin AA children. Subjects were admitted into the ward for 24 hours. Anthropometric, blood pressure measurements were obtained and urine samples collected over 24hours and 3mls of venous blood was taken for biochemical analysis.Results: There were 70 males and 50 females with M:F ratio 1.4:1. There were equal numbers of both SCA and control subjects. The obtained mean (SD) GFR was  127.9(38.5) ml/min/1.73m2 for the SCA group and 126.6(20.2) ml/min/1.73m2 for the control group, with t-value 0.23; degree of freedom, 118 and p-value of 0.824.Conclusion: The mean (SD) GFR of SCA children in steady state is within normal range.Keywords: Steady state,  SCA children, GFR, North western Nigeria
