Evaluation of the Community Cataract Surgical Services of a University Teaching Hospital Using Cataract Surgical Coverage in Nigeria

Background: Cataract is the leading cause of blindness in the world. An efficient and effective cataract surgical service is necessary to reduce the backlog of cataract blindness in the community. This study aims to determine the cataract surgical coverage among individuals aged 50 years and above residing in Esie and Arandun communities. This will serve as a measure of the impact of the cataract intervention programme provided by the University of Ilorin Teaching Hospital, Nigeria.Methods: The study was a population-based, cross sectional survey conducted from November to December, 2013. Cataract surgical services are provided by the University of Ilorin Teaching Hospital, Nigeria, at Esie and Arandun communities as out-reach centres. Seven hundred and fifty-five individuals aged 50 years and above residing in these communities had basic ocular examination done.Result: Out of the 765 subjects registered, 755(98.7%) were examined. Out of these, 38.4% were males and 61.6% were females. The prevalence of bilateral cataract blindness was 1.6%. The Cataract Surgical Coverage (eyes) at visual acuity < 3/60 for males and females were 52.3% and 51.2% respectively (X2=19.30, p=0.001), while the Cataract Surgical Coverage (person) at visual acuity less < 3/60 for males and females were 80.6% and 68.4% respectively (X2=2.10, p=0.147).Conclusion: The Cataract Surgical Coverage was high with a correspondingly low prevalence of cataract blindness in these communities. The availability of cataract surgical services via out-reach programmes bridges the gap between eye care-givers and the community.Keywords: Cataract Surgical Coverage, Cataract Surgical Services, Community, Evaluatio

Awareness of Diabetic Retinopathy among patients with Diabetes Mellitus in Ilorin, Nigeria

Background: Diabetic retinopathy is a major cause of blindness worldwide. The associated loss of productivity and quality of life of the patients with diabetic retinopathy will lead to additional socioeconomic burden. This study aims to determine the level of awareness of diabetic retinopathy among diabetic patients. Materials and Methods: This hospital-based cross sectional study, was carried out at the Diabetic and Ophthalmology clinics of University of Ilorin Teaching Hospital, Nigeria from November 2011 to July 2012. A total of 365 patients had validated, semi-structured, and interviewer-administered questionnaires to obtain information on socio-demographic characteristics, clinical information and awareness of diabetic retinopathy. Results: A total of 365 patients were enrolled, with age between 19 and 90 years, and a mean of 45.8 ±16.3 years. The male to female ratio was 1: 2.2. Ninety-nine respondents (27.1%) had no education. The majority (30.4%) had only primary education; 21.1% had tertiary; 14.5% had secondary while 6.8% had Quranic education. The mean duration of diabetes mellitus was 14.1 ±13.09 years. Of the 365 patients with diabetes mellitus, 279(76.4%) had heard that diabetes mellitus affects the eyes, while 86(23.6%) had not. Of those who had heard, 221(79.2%) heard it from health personnel, 45(16.1%) from radio/television, 25(9.0%) from internet, 23(8.2%) from books/newspapers, while 16(5.7%) heard from other sources.Conclusion: There was a high level of awareness of diabetic retinopathy amongst the patients. However, the high level of awareness of the blinding complication of diabetes mellitus did not translate to a correspondingly high level of ocular examination for diabetic retinopathy. 

Hepatitis C virus infection in Nigerians with diabetes mellitus

ABSTRACT It has been reported from several Caucasian studies that there is an epidemiological association between hepatitis c virus infection and diabetes mellitus. The objective of this study was to determine whether any such relationship exists in a black African population. To determine the prevalence of Hepatitis C virus infection in Nigerians with diabetes mellitus in North-Eastern Nigeria. Hospital -based cross-sectional study. Medical out-patient clinic and the Blood bank of the Federal Medical Centre, Yola. Nigeria. From June, 2008 to December 2009, Two hundred and eighty consecutively recruited diabetes mellitus patients comprising 108 males and 172 females were screened for HCV infection. These were compared with five hundred and ninetyfive voluntary blood donors who were screened during the same period. Serological testing for HCV infection was carried out with anti-HCV using Enzyme Linked Immuno-sorbent Assay (ELISA) method. The bio-data of the patients, history and duration of diabetes mellitus, history of jaundice, blood transfusion were recorded on a proforma. Out of the 280 diabetes mellitus patients tested, twenty-six were positive for anti-HCV antibodies giving an infection rate of 9.3% compared with fourteen subjects out of 595 voluntary blood donors 2.4% (p=0.0000105). History of blood transfusion, and jaundice was positively correlated with presence of HCV infection in diabetic patients. Hepatitis C virus is more common in Nigerian patients with diabetes mellitus than in non-diabetic control subjects. It may be necessary to screen patients with diabetes mellitus for hepatitis c virus infection particularly those with history of blood transfusion and jaundice

A Fibreoptic Endoscopic Study of Upper Gastrointestinal Bleeding at Bugando Medical Centre in Northwestern Tanzania: a Retrospective Review of 240 Cases.

Upper gastrointestinal (GI) bleeding is recognized as a common and potentially life-threatening abdominal emergency that needs a prompt assessment and aggressive emergency treatment. A retrospective study was undertaken at Bugando Medical Centre in northwestern Tanzania between March 2010 and September 2011 to describe our own experiences with fibreoptic upper GI endoscopy in the management of patients with upper gastrointestinal bleeding in our setting and compare our results with those from other centers in the world. A total of 240 patients representing 18.7% of all patients (i.e. 1292) who had fibreoptic upper GI endoscopy during the study period were studied. Males outnumbered female by a ratio of 2.1:1. Their median age was 37 years and most of patients (60.0%) were aged 40 years and below. The vast majority of the patients (80.4%) presented with haematemesis alone followed by malaena alone in 9.2% of cases. The use of non-steroidal anti-inflammatory drugs, alcohol and smoking prior to the onset of bleeding was recorded in 7.9%, 51.7% and 38.3% of cases respectively. Previous history of peptic ulcer disease was reported in 22(9.2%) patients. Nine (3.8%) patients were HIV positive. The source of bleeding was accurately identified in 97.7% of patients. Diagnostic accuracy was greater within the first 24 h of the bleeding onset, and in the presence of haematemesis. Oesophageal varices were the most frequent cause of upper GI bleeding (51.3%) followed by peptic ulcers in 25.0% of cases. The majority of patients (60.8%) were treated conservatively. Endoscopic and surgical treatments were performed in 30.8% and 5.8% of cases respectively. 140 (58.3%) patients received blood transfusion. The median length of hospitalization was 8 days and it was significantly longer in patients who underwent surgical treatment and those with higher Rockall scores (P < 0.001). Rebleeding was reported in 3.3% of the patients. The overall mortality rate of 11.7% was significantly higher in patients with variceal bleeding, shock, hepatic decompensation, HIV infection, comorbidities, malignancy, age > 60 years and in patients with higher Rockall scores and those who underwent surgery (P < 0.001). Oesophageal varices are the commonest cause of upper gastrointestinal bleeding in our environment and it is associated with high morbidity and mortality. The diagnostic accuracy of fibreoptic endoscopy was related to the time interval between the onset of bleeding and endoscopy. Therefore, it is recommended that early endoscopy should be performed within 24 h of the onset of bleeding

Strengthening retinopathy of prematurity screening and treatment services in Nigeria: a case study of activities, challenges and outcomes 2017-2020.

OBJECTIVES: Retinopathy of prematurity (ROP) will become a major cause of blindness in Nigerian children unless screening and treatment services expand. This article aims to describe the collaborative activities undertaken to improve services for ROP between 2017 and 2020 as well as the outcome of these activities in Nigeria. DESIGN: Descriptive case study. SETTING: Neonatal intensive care units in Nigeria. PARTICIPANTS: Staff providing services for ROP, and 723 preterm infants screened for ROP who fulfilled screening criteria (gestational age <34 weeks or birth weight ≤2000 g, or sickness criteria). METHODS AND ANALYSIS: A WhatsApp group was initiated for Nigerian ophthalmologists and neonatologists in 2018. Members participated in a range of capacity-building, national and international collaborative activities between 2017 and 2018. A national protocol for ROP was developed for Nigeria and adopted in 2018; 1 year screening outcome data were collected and analysed. In 2019, an esurvey was used to collect service data from WhatsApp group members for 2017-2018 and to assess challenges in service provision. RESULTS: In 2017 only six of the 84 public neonatal units in Nigeria provided ROP services; this number had increased to 20 by 2018. Of the 723 babies screened in 10 units over a year, 127 (17.6%) developed any ROP; and 29 (22.8%) developed type 1 ROP. Only 13 (44.8%) babies were treated, most by intravitreal bevacizumab. The screening criteria were revised in 2020. Challenges included lack of equipment to regulate oxygen and to document and treat ROP, and lack of data systems. CONCLUSION: ROP screening coverage and quality improved after national and international collaborative efforts. To scale up and improve services, equipment for neonatal care and ROP treatment is urgently needed, as well as systems to monitor data. Ongoing advocacy is also essential

Cholelithiasis and type 2 diabetes mellitus in Nigerians

Background: Gallstone disease is one of the most common gastrointestinal diseases seen in clinical practice. Individuals with Diabetes mellitus are reported to have a 2 to 3-fold increase in the incidence of cholesterol Gallstone. Studies have shown a higher prevalence of Gallstone disease in patients with Diabetes mellitus. However there is no literature on Gallstone disease and the Nigerian type 2 diabetic patients. This study was therefore designed to determine the prevalence of Gallstone disease using abdominal ultrasound scan amongst Nigerians with type 2 Diabetes mellitus. Methodology: 100 type 2 diabetic patients and 100 age and sex- matched controls under-went real time ultrasonography to determine the prevalence of Gallstone disease. Result: 15% of the diabetic patients had ultrasound evidence of Gallstone disease as compared to 7% in non diabetic controls. Conclusions: Gallstone disease in Nigerians with type 2 Diabetes mellitus may not be rare. South African Gastroenterology Vol. 5 (3) 2007: pp. 14-1
