    Retinopathy of prematurity in a tertiary facility: an initial report of a screening programme
    (Paediatric Association of Nigeria, 2020) Olusanya, B. A.; Oluleye, T. S.; Tongo, O. O.; Ugalahi, M. O.; Babalola, Y. O.; Ayede, A. I.; Baiyeroju, A. M.
    Retinopathy of prematurity (ROP) screening in Nigeria is at a nascent stage and at the moment there are no National guidelines for ROP screening in Nigeria. Thus it is desirable for screening programs to report findings amongst screened preterm infants in order to facilitate the development of national ROP screening criteria and guidelines. The aim of this report is to describe the frequency, severity and risk factors for retinopathy of prematurity (ROP) among preterm and very low-birth-weight babies screened within the first year of initiating an ROP screening program at a Nigerian tertiary facility. Methods: A cross-sectional study of infants born at less than 34 weeks gestational age; or with birth weight less than 1500g between May 2016 and May 2017. ROP screening examinations were performed by ophthalmologists with the use of an indirect ophthalmoscope, after pupillary dilation, in collaboration with the neonatology team. Information on gestational age at birth, birth weight, oxygen therapy and presence of other risk factors were recorded and analyzed. Results: A total of 74 infants were screened during the period. There were 36 (48.6%) males. Mean gestational age at birth was 29.6 (±2.35) weeks. Mean birth weight was 1.26 (±0.27) kg with a range of 800 to 1950g. ROP was detected in 9 (12.2%) infants. Two (22.2%) of these had Threshold ROP. There was no significant difference between the mean birth weight and mean gestational age of the infants who had ROP compared to those without ROP. The two infants with Threshold ROP were treated with intravitreal Bevazicumab and had regression of ROP. Conclusion: Retinopathy of prematurity was diagnosed in at risk infants in this facility. There is, therefore, a need to establish ROP screening programs in all neonatal units across the country. In addition, established programs need to evaluate their screening criteria with a view towards developing country-specific screening guidelines.

    Congenital aniridia: clinical profile of children seen at the University College Hospital, Ibadan, South-West Nigeria
    (SAGE Publishing, 2021) Ugalahi, M. O.; Ibukun, F. A.; Olusanya, B. A.; Baiyeroju, A. M.
    Purpose: To describe the clinical features of patients younger than 16 years with aniridia presenting to the Paediatric Ophthalmology unit of the Eye Clinic, University College Hospital, Ibadan, Nigeria. Methods: The is a retrospective review of children with aniridia seen between May 2015 and April 2019 at the Paediatric Ophthalmology unit of the Eye Clinic, University College Hospital in Ibadan. Data on demographic characteristics, presenting complaints, ocular and systemic examination findings, and interventions were collected and descriptively summarised. Results: A total of 28 eyes of 14 patients were studied. The mean age was 6.37 ± 4.98 years. Seven (50%) patients were male. Aniridia was diagnosed in first-degree relatives of nine patients. The most common complaint at presentation was poor vision in 11 (78.6%) patients. Objective visual acuity assessment was obtained in 22 (78.6%) eyes. Presenting visual acuity was worse than 20/60 in all 22 eyes and worse than 20/400 in 8 (36.4%) eyes. Refraction was performed in 17 (60.7%) eyes and revealed a mean spherical equivalent of −3.93 ± 5.99 diopters. Twenty (71.4%) eyes had corneal opacities, and lenticular opacities were seen in 15 (62.5%) of 24 eyes. Mean intraocular pressure (IOP) at presentation was 21.62 ± 10.4 mmHg; 12 (41.4%) eyes had elevated IOP at presentation. Ten (35.7%) eyes had cataract surgery and six (21.4%) eyes had glaucoma surgery. Conclusion: Familial aniridia was common in this study, and most of the patients presented with moderate to severe visual impairment. The common ocular associations were refractive error, cataract, corneal opacity and glaucoma.

    Age at detection and age at presentation of childhood cataract at a tertiary facility in Ibadan, Southwest Nigeria
    (2020) Olusanya, B. A.; Ugalahi, M. O.; Adeyemo, A. O.; Baiyeroju, A. M.
    Background: To describe factors which influence the age at detection and age at presentation of patients with childhood cataract at a tertiary eye care facility in Southwest Nigeria. Methods: A retrospective review of children who presented with cataract between 2011 and 2015. Case notes were reviewed and data on age at detection and presentation as well as other clinical information was collected and analyzed using Stata 12 statistical software. Results: A total of 164 cases were reviewed, 52.4% of them were boys. Median age at presentation was 48 months while the median age at detection was 13.5 months. Seventy-four (45.1%) children had congenital cataract, 31.1% had developmental cataract, and 21.3% had traumatic cataract. The child’s mother detected the cataract in 116 (70.7%) of the patients. Median age at presentation for patients with congenital cataract was 18 months and 84 months for developmental cataract. The median age at presentation for congenital cataracts that were noticed by the mother was 17 months compared with 72 months for those noticed by other caregivers (p = 0.0085). The median age at presentation for developmental cataracts that were noticed by the mother was 72 months compared with 114 months for those noticed by other caregivers (p = 0.0065). Gender of the child did not significantly influence the age at detection or presentation. The source of referral and the location of domicile did not significantly affect the time interval between detection of the cataract and presentation to hospital. Conclusion: The average age of children presenting with cataracts in our setting is older than in high income countries. Detection of the cataract by the mother increases the likelihood of early presentation; thus, focused maternal education may promote earlier detection and presentation.

    Outcome of surgery for traumatic cataract in children in a child eye health tertiary facility, Ibadan, Nigeria
    (SAGE Publishing, 2021-03) Ugalahi, M. O.; Olusanya, B. A.; Aremu, O. O.; Baiyeroju, A. M.
    Objective: The objective of this study was to describe the outcome of surgery for traumatic cataract and associated factors in children aged 16 years and below operated in a tertiary facility. Methods: This was a retrospective review of records of children who had surgery for traumatic cataract between August 2015 and August 2019. Information on biodata, preoperative visual acuity, surgical methods, complications, and postoperative visual acuity were retrieved. Data were analyzed using IBM SPSS Statistics 20.0. Results: Traumatic cataract accounted for 87 (14.7%) of 593 eyes operated for childhood cataract during the period. Of these, a total of 79 records were available for review. There were 56 (70.9%) males with a mean age of 10.11 (±3.39) years. All injuries were unilateral; closed globe injuries accounted for 70 (88.8%) of the cataracts and the left eye was affected in 42 (53.2%) patients. Fifty-two (67.09%) eyes had other ocular injuries apart from cataracts. The morphology of the cataract was membranous in 44 (55.7%) eyes, and 76 (96.2%) eyes had cataract surgery with intraocular lens (IOL) implantation; 39 (51.3%) of these IOLs were implanted within the capsular bag. The preoperative best corrected visual acuity was worse than 6/18 in all 79 (100%) eyes and improved to 6/18 or better in 32 (40.5%) eyes at 3 months postoperatively. Conclusion: Traumatic cataract accounted for less than a quarter of all childhood cataracts in our center. Majority of the eyes had successful IOLs implantation during surgery, and the best corrected visual acuity improved in a moderate proportion of these patients.

    Ocular injuries in a paediatric population at a child eye health tertiary facility, Ibadan, Nigeria
    (Elsevier, 2023) Ugalahi, M. O.; Adebusoye, S. O.; Olusanya, B. A.; Baiyeroju, A.
    Purpose: To determine the pattern, causes and risk factors for ocular injuries amongst children presenting to a tertiary facility in Ibadan, southwest Nigeria Methods: A retrospective review of clinical records of patients aged 16 years and below who presented with ocular injuries to the eye emergency unit between May 2010 and April 2016. Information extracted includes patient’s demography, location and circumstances of injury, clinical findings, and management. Data was analysed using IBM SPSS Statistics for Windows, Version 26.0. Descriptive and inferential statis- tics were calculated. Odds ratio were derived from regression models adjusted for confounders. Significance was set at a P-value of 0.05. Results: A total of 109 children were studied. Majority were boys (male to female ratio = 2.9:1). The median age at presentation was 9 years. Injury occurred at home in 67 (61.5%) children, and at school in 30 (27.5%). More than half of the children were injured during play, 18 (16.5%) during corporal punishment, and 34 (31.2%) by accidents during domestic/schoolwork. Majority (73.4%) were closed globe injuries. The odds of injury with sharp objects and ocular trauma score of 4 or less was were 3.2 times (95% Confidence interval {CI}: 1.3–7.7) and 3.9 times (95% CI:1.4–11.4) higher in children aged 0–5 years respectively. The odds of open globe injury was 9.8 times (95% CI: 3.4–28.6) higher in injury from sharp objects. Wood/stick, cane, stone, broomstick and fist/palm/finger were the agents responsible for two- thirds of injuries. Conclusion: This study revealed that children predominantly sustain ocular injuries at home and younger children have greater odds of severe injuries with profound implications for visual disability. Health education, adult supervision and the application of appropriate measures necessary for reducing the incidence and severity of childhood ocular trauma are advocated.

    Management of primary childhood glaucoma: evaluation of practice, practice gaps, and needs in a low‑resource country
    (Wolters Kluwer - Medknow, 2024) Ugalahi, M.||||||||A. | ||; Sarimiye, T. F.; Obajolowo, T.; Nkanga, E. D.; Abdulrahman, A.; Olusanya, B.; Baiyeroju, A.
    Purpose: To evaluate the current practice, equipment availability, and training needs for managing childhood glaucoma in Nigeria. Materials and Methods: An online questionnaire (Google Forms) was distributed through E-mails and social media platforms of pediatric ophthalmologists and glaucoma specialists who practice in Nigeria and manage glaucoma in children aged 0–16years. Information concerning sociodemographic characteristics, type of practice, location of practice, years of practice, status, and preferred practices in the management of childhood glaucoma cataracts were obtained and analyzed with SPSS. Results: Thirty (23.3%) out of 129 eligible participants indicated they perform glaucoma surgeries in children. The majority (66.6%) had practiced as specialists for 10years or less, and 70% were pediatric ophthalmologists. A third of the respondents practiced in the country’s southwest region, with none in the Northeast region. The most common surgery performed for primary congenital glaucoma was combined trabeculotomy trabeculectomy, while trabeculectomy was the most common surgery performed for juvenile open-angle glaucoma. Two respondents reported performing glaucoma drainage device surgery and seven reported possessions of skills for goniotomy. All centers had trabeculectomy instrument sets, while three centers had facilities for endolaser cyclophotocoagulation, and only two centers had knives for goniotomy. Antimetabolites were routinely used for childhood glaucoma surgeries by 26(86.7%) respondents, and the most common antimetabolite used was mitomycin (21; 80.8%). Conclusion: There is a need for the development of in-country training programs and the exchange of skills through collaboration among those providing glaucoma services within Nigeria to improve the care of children with glaucoma.

    Exposure to agrochemicals and markers of kidney damage among farmers in rural communities in Southwestern Nigeria
    (2021) Ajayi, S.O.; Raji, Y.R.; Michael, O.S.; Adewole, D.; Akande, T.; Abiola, B.; Aminu, S.; Olugbenga-Bello, A.; Arije, A.
    Background: Chronic kidney disease of unknown origin (CKDu) is assuming an epidemic proportion, especially in farming communities worldwide. We explored the relationship between CKD markers and agrochemical exposure among rural farmers in South Western Nigeria. Methods: We studied selected farming communities in Southwestern Nigeria where the use of agrochemicals was widespread. A pre-tested questionnaire was administered to participants. Anthropometric data, information on use of agrochemicals; urine and blood samples were obtained. Informed consent was obtained from participants. The study was approved by the Institutional Ethics committee and complied with 1975 Helsinki declaration, as revised in 2000. Results: A total of 438 farmers made up of 202 males (46.1%) and 236 females (53.9%) were studied. The mean microalbuminuria was 30.2 ±11.7 mg/dl. Majority of the farmers had CKD stage 2 (42.0%) and CKD stage 3 (37.7%). The type of farming engaged in had a positive, but not significant, correlation with eGFR (r=0.012, p=0.832). There was positive correlation between type of farming and GFR category (r=0.24, p=0.000). Frequency of use of hexachlorocyclohexane had a positive and significant correlation with eGFR (r=0.111, p=0.045). Annual crop farming had a correlation with UACR (r=0.149, p=0.024). Conclusion: Annual crop farming had a positive correlation with UACR, eGFR and GFR category. The prolonged use of agrochemicals on an annual basis can cause kidney damage.

    Association between depression and hypertension in the Ibadan Study of Ageing. African
    (2020) Ajayi, S.O.; Oladeji, B.; Abiona, T.; Gureje, O.
    Introduction: The elderly population is growing all over the world with attendant increase in occurrence of comorbid conditions. Using data from a longitudinal study of community-dwelling elderly persons in Nigeria, we explored the prevalence and corelates of hypertension and depression as well as the factors associated with the comorbidity of these two conditions. Methods: The Ibadan Study of Ageing, a longitudinal community-based cohort study conducted between 2003 and 2009 on the profile and determinants of successful ageing. A multistage cluster random sampling was used to select a cohort of elderly participants from across eight contiguous Yoruba speaking states in Nigeria- Ekiti, Kogi, Kwara, Lagos, Ogun, Ondo, Osun, and Oyo. Participants (non-institutionalized elderly, aged 65 years or over) were assessed at 4 time points: baseline(2003/2004) and annually from 2007 (wave 1), 2008 (wave 2 and 2009 (wave 3). Data was collected in face-to-face interviews; depression was assessed using the World Mental Health initiative version of the Composite International Diagnostic Interview (CIDI), social engagement was assessed using an adapted World Health Organization Disability Assessment Schedule WHODAS) and functional disability using activities of daily living (ADL) and instrumental activities of daily living (IADL). Hypertension was defined according to the Joint National Committee-7(JNC7) recommendations as systolic blood pressure of 140 mmHg and above, diastolic blood pressure of 90mmHg. This current study is based on cross-sectional data from the wave 1(2007) assessment. Results: Of the 1597 participants, 58% were females and 42% were 70 years and older. The mean age was 74.2 years (SD ±7.8). Nine hundred and ninety-eight (62.5%) participants had hypertension while 177 (10.6%) met the criteria for major depression while comorbid depression and hypertension was present in 122 (7.1%). The comorbidity of hypertension and depression was significantly associated with gender (higher in women) (p=0.001), insomnia (p=0.001), lack of family participation (p=0.001), lack of community participation (p=0.002), and experiencing a negative life event in the past year (p=0.003). In a multivariate analysis, lack of participation in family activities was associated with an increased risk of co-morbidity between hypertension and depression (OR 4.51, p=0.000, CI 2.14-9.50). Conclusions: These findings suggest that the comorbidity of depression and hypertension could potentially be minimized by modifying social risk factors such as keeping the elderly involved in family and community life participation by promoting their involvement in recreational and volunteer activities as well as social gatherings.

    Challenges and possible solutions to peritoneal dialysis use in Nigeria.
    (2020) Ajayi, S.; Raji, Y.; Bello, T.; Arije, A.
    Introduction: peritoneal dialysis is a form of renal replacement therapy that is both effective and relatively affordable. Peritoneal dialysis (PD) was first used in Nigeria as a treatment option for renal failure. Its use was first reported in Nigeria in 1969 and became more widespread in the 80s and 90s. Haemodialysis, which is capital intensive to set up and requires infrastructures and facilities such as electricity, intense water consumption and buildings, seems to have upstaged peritoneal dialysis both in demand and supply. Methods: this cross-sectional study is a convenient survey of nephrologists, renal technicians and nurses in Nigeria. We used a structured, self-administered questionnaire on a cross-section of members and associate members attending a national nephrology association meeting. Results: there were 68(54.4%) doctors, 43(27.2%) nurses, and 14(11.2%) renal technicians, all from medical institutions with renal treatment programs who participated in the study. The most common problems encountered with PD use are financial constraints (51.7%), inadequate fluid supply (50%), frequent line blockage (22.4%) and frequent infections (17.2%). Reasons attributed to the stoppage of PD in the centres included lack of PD fluids (50.8%), unavailability of PD catheters (22.8%), lack of expert personnel to train (15.8%). Conclusion: main challenges to peritoneal dialysis use in Nigeria include limited experience and training and availability and cost of consumables. Effort to overcome the factors militating against its use should be positively pursued so that peritoneal dialysis will be reintegrated into the mainstream of renal replacement therapy once more

    Assessment of iron deficiency anaemia and its risk factors among adults with chronic kidney disease in a tertiary hospital in Nigeria
    (2021) Raji, Y.R.; Ajayi, S.O.; Gbadegesin, B.A.; Bello, T.O.; Salako, B.L.
    A substantial proportion of patients with chronic kidney disease (CKD) develop iron deficiency anaemia (IDA). Despite the association of IDA with adverse cardiovascular outcomes, it remains underdiagnosed and poorly managed. Up to 70% of patients with CKD are anaemic at the time of initiating dialysis, while the predictors of IDA in these patients in our setting are unknown. This study aimed to determine the prevalence and risk factors for IDA in patients with CKD. Materials and Methods: This is a case–control study of 157 patients with CKD and 157 age and gender matched subjects without CKD. Information obtained from the participants were socio demographic details, aetiology of CKD, medication history and features of IDA. All participants had serum ferritin, total iron binding capacity (TIBC), transferrin saturation (TSAT), highly sensitive C reactive protein, serum creatinine and complete blood count determined. Results: The median estimated glomerular rate (22.7 [3.4–59.5] vs. 110.2 [60.3–152.8] ml/min/1.73 m2 , P < 0.01), the mean haemoglobin concentration (9.3 ± 2.6 vs. 11.4 ± 1.7 g/dl, P < 0.01), and TSAT (27.9% ± 6.4% vs. 34.8% ± 8.1%, P < 0.04) were significantly lower in patients with CKD. The mean age, serum ferritin and TIBC were similar in both groups. The prevalence of absolute (24.8% vs. 13.4%, P < 0.01) and relative (17.8% vs. 7.6%, P < 0.01) iron deficiencies were higher among individuals with CKD compared to the controls. Female gender (odd ratio [OR]:1.50, 95% confidence interval [CI]:1.0267–4.1163, P < 0.04) and severity of CKD (OR: 3.43, 95% CI: 1.5568–7.8324, P < 0.02) were independently associated with IDA. Conclusion: IDA is common among individuals with CKD while female gender and severity of CKD were factors that independently predicted IDA
