ABSTRACT

BACKGROUND: : Visual morbidities increase the burden of care and negatively impact the quality of life of older people. Few empirical reports exist on the visual status of older Nigerians. AIM: This study describes the visual morbidities and determinants of visual impairment among persons aged 60 years and above who presented at a geriatric center in southwestern Nigeria and discusses the merits of focused geriatric care at a single location. MATERIALS AND METHODS: Data were obtained from electronic health records and case files of 628 older patients (≥60 years) who attended the facility between January 1, 2014 and December 31, 2018. Data extracted included, age, sex, married status, occupational status, visual acuity, eye diagnoses, eye medications, previous surgeries, and anthropometric measurements. RESULTS: Mean age of patients was 70.1 ± 7.4 years and 378 (60.2%) were females. Two out of every three patients had more than one visual diagnosis. Significantly, glaucoma (P < 0.001) and cataract (P = 0.01) were common among men, whereas dry eye syndrome (P < 0.001) and allergic conjunctivitis (P = 0.01) were common in women. Antiglaucoma medications (55.8%) were the commonest medications used and 21.0% had previous eye surgery. Assessment of presenting visual acuity demonstrated that 28.7% of patients had moderate-severe visual impairment (MSVI) in both eyes at presentation while 10.3% were bilaterally blind. Increasing age (P < 0.001) and male sex (P = 0.01) were the factors significantly associated with blindness. CONCLUSION: MSVI and blindness were common in our setting with glaucoma and cataract being the most prevalent associated diagnosis. Information obtained should stimulate advocacy for the prompt management of preventable causes of poor vision in older Nigerians.

ABSTRACT

BACKGROUND: Orbito-ocular diseases are a major public health issue, often causing visual impairment with serious socioeconomic implications on individual lives. Ocular ultrasonography is an invaluable diagnostic tool when clinical examination of the ocular fundus is difficult. OBJECTIVES: To describe the indications, sonographic findings, and contribution of orbito-ocular ultrasonography to the management of orbito-ocular diseases in the University College Hospital, Ibadan. MATERIALS AND METHODS: A retrospective review of B-mode ocular ultrasound findings and hospital data of all patients referred to the Radiology department of the University College Hospital, Ibadan for ocular Ultrasound between January 2014 - December 2018. RESULTS: There were 142 patients, aged 1-85 years, (median age =28 years). 72 (50.7%) patients were under 30 years of age, and 50 (35.2%) were pediatric cases. Male to female ratio was 1.84:1. The commonest presenting complaint was blurred vision in 97 (68.3%) cases, followed by eye trauma in 54 (38.0%). B-mode Ultrasound, demonstrated cataract in 63 (44.4%,) cases, vitreous hemorrhage in 42 (29.6%), retinal detachment in 27 (19.0%), vitreous detachment in 19 (13.4%), normal findings in 17 (12%) and orbital tumors in 13 (9.2%) patients. B-mode ultrasound scan and clinical diagnosis demonstrated good agreement in 91 /142 cases (64.1%), partial agreement in 23/142 (16.2%) cases, and no agreement in 28 (19.7%). Kappa agreement scores, K were 74.3% and 70.9%, for ruptured globe and cataract respectively. CONCLUSION: Orbito-ocular ultrasonography contributes significantly to the diagnosis of orbito-ocular disease and shows good correlation with clinical diagnoses. However, a future study with larger numbers is required.

ABSTRACT

According to World Health Organization, health not only refers to the absence of physical diseases, but also includes psychological and social well-being of individuals.[1] Quality of life (QoL) on the other hand, lacks a single, universally accepted definition.[2] However, QoL may be defined subjectively as "an individual's perception of his/her life in the context of the culture and value system in which they live, and in relation to their goals, expectations, standards and concerns.[3] QoL also has an objective component which can be measured objectively using validated instruments (e.g. questionnaires) in which a score is assigned to specific indices or characteristics in different domains along a scale in a continuum.[4],[5],[6]Visual function is important for optimal orientation in functional and social life and has effects on physical, psychological, mental and emotional well-being of the individual.[7] Visual function therefore is a domain under which QoL may be assessed. This is referred to as vision-specific or vision-related QoL. The National Eye Institute Visual Function Questionnaire (NEI-VFQ) is an example of an instrument designed and validated for the objective assessment of vision-specific QoL.[8]Broman et al.[9] revealed that a visual acuity of at least 6/12 was found to negatively impact on n individual's quality of life. This was also reiterated by Bekibele et al.[10] The Proyecto VER study[9] observed that visual impairment was associated with a decrease in the quality of life among elderly patients, and that the severity of ocular diseases was related to the level of visual impairment. In relation to persons with no visual impairment, persons with bilateral mild and unilateral or bilateral moderate or severe visual impairment report greater difficulties in performing most vision-dependent daily activities, experience vision-related dependency and poorer vision-related mental health.[11]Ee Munn Chia et al.[12] further disclosed that the impact of visual impairment on mental domains was much greater compared to co-existing medical conditions like stroke.Therefore, data is needed on the effect of ocular diseases on vision-related quality of life among the elderly for the purpose of making recommendations for improved eye care with resultant improvement in their quality of life

ABSTRACT

BACKGROUND: Operative interventions are uncommonly required for penetrating pulmonary injuries. Similarly, because their incidence is low, few series appear sporadically in the literature. Objectives of this study are to identify predictors of outcome for patients requiring emergent thoracotomy for penetrating pulmonary injuries and evaluate the use of tissue sparing versus resective techniques for their management. STUDY DESIGN: This is a retrospective 169-month study of all patients with penetrating pulmonary injuries requiring thoracotomy. The main outcome measures are: physiologic parameters, AAST-OIS injury grade, surgical procedures and mortality. Statistical analysis includes univariate and stepwise logistic regression. RESULTS: 101 patients required thoracotomy for penetrating pulmonary injuries. Mechanism of injury includes: gunshot wounds (GSW)-73 (72%), stab wounds (SW)-28 (33%). Mean systolic BP 97 ± 47, mean HR 92 ± 47, and mean admission pH 7.22 ± 0.17. Mean RTS 6.25 ± 2.7, mean ISS 36 ± 22. The mean estimated blood loss (EBL) was 5277 ± 4955 mls. Predictors of outcome are: admission pH (p = 0.0014), admission base deficit (p < 0.0001), packed red blood cells (PRBCs) transfused (p = 0.023), whole blood transfused (p < 0.01). A total of 143 procedures were required in 101 patients: tissue sparing 114 (80%) versus resective procedures 29 (20%). Only pneumonectomy (p = 0.024) predicted outcome. Overall survival 64/101-64%. American Association for the Surgery of Trauma-Organ Injury Scale (AAST-OIS) injury grades I-III versus IV-VI predicts survival (p < 0.001). Stepwise logistic regression identified AAST-OIS injury grades IV-VI (p = 0.007; OR 6.38 [95% CI 1.64-24.78]), intraoperative dysrhythmias (p = 0.003; OR 17.38 [95% CI 2.59-116.49]) and associated cardiac injuries (p = 0.02; OR 8.74 [95% CI 1.37-55.79]) as independent predictors of outcome. CONCLUSIONS: Predictors of outcome for penetrating pulmonary injuries requiring thoracotomy are identified and must be taken into account in their operative management. Tissue sparing techniques-stapled pulmonary tractotomy is once again validated, and it remains effective as the mainstay for their management; however, only pneumonectomy predicts outcome. AAST-OIS injury grades IV-VI predict outcome with higher injury grades requiring resective procedures.

ABSTRACT

BACKGROUND: Penetrating cardiac injuries are uncommon and lethal. The objectives of this study are to examine the national profile of cardiac injuries, identify independent predictors of outcome, generate, compare and validate previous predictive models for outcomes. We hypothesized that National Trauma Data Bank (NTDB) given its large number of patients, would validate these models. METHODS: The NTDB was queried for data on cardiac injuries, using survival as the main outcome measure. Statistical analysis was performed utilizing univariate and stepwise logistic regression. The stepwise logistic regression model was then compared with other predictive models of outcome. RESULTS: There were 2016 patients with penetrating cardiac injuries identified from 1,310,720 patients. Incidence: 0.16%. Mechanism of injury: GSWs-1264 (63%), SWs-716 (36%), Shotgun/impalement-19/16 (1%). Mean RTS 1.75, mean ISS 27 ± 23. Overall survival 675 (33%). 830 patients (41%) underwent ED thoracotomy, 47 survived (6%). Survival stratified by mechanism: GSWs 114/1264 (10%), SWs 564/717 (76%). Predictors of outcome for mortality-univariate analysis: vital signs, RTS, ISS, GCS: Field CPR, ED intubation, ED thoracotomy and aortic cross-clamping (p < 0.001). Stepwise logistic regression identified cardiac GSW's (p < 0.001; AOR 26.85; 95% CI 17.21-41.89), field CPR (p = 0.003; AOR 3.65; 95% CI 1.53-8.69), the absence of spontaneous ventilation (p = 0.008; AOR 1.08, 95% CI 1.02-1.14), the presence of an associated abdominal GSW (p = 0.009; AOR 2.58, 95% CI 1.26-5.26) need for ED airway (p = 0.0003 AOR 1386.30; 95% CI 126.0-15251.71) and aortic cross-clamping (p = 0.0003 AOR 0.18; 95% CI 0.11-0.28) as independent predictors for mortality. Overall predictive power of model-93%. CONCLUSION: Predictors of outcome were identified. Overall survival rates are lower than prospective studies report. Predictive model from NTDB generated larger number of strong independent predictors of outcomes, correlated and validated previous predictive models.

ABSTRACT

BACKGROUND: To identify the determinants of recurrence following primary pterygium excision combined with conjunctival autograft (CAG) and intraoperative use of Mitomycin C (MMC) or 5-Fluorouracil (5-FU). METHODS: A randomized controlled clinical trial comparing 5-FU (50 mg/ml) plus CAG versus MMC (0.01%) plus CAG in preventing recurrence of primary pterygium following excision. RESULTS: A total of 80 eyes of 80 subjects were studied, with 46 eyes in the 5-FU group and 34 eyes in the MMC group. The mean age was 50.7 +/- 13.1 years with a male: female ratio of 0.95:1. Mean follow up period was 35.2 +/- 29.1 weeks. The overall recurrence rate was 10%, with a rate of 8.7% in the 5-FU group and 11.8% in the MMC group. The mean age of the patients who had a recurrence was 38.1 +/- 13.3 years compared to 52.1 +/- 12.4 years in those without a recurrence (p = 0.003). The median size of the pterygium in patients who had a recurrence was 3.2mm, while the median size in patients who did not have a recurrence was 3.0mm (p = 0.8). Five (12.8%) males had a recurrence compared to three (7.3%) females (p = 0.48); while 10.5% of fleshy pterygia recurred compared to none (0%) of the non-fleshy pterygia (p = 1.00). CONCLUSION: Younger age remains a risk factor for recurrence when both CAG and antimetabolites are combined in the treatment of pterygium, while the effect of gender, size and morphology of the pterygium may be diminished by such combination.

ABSTRACT

BACKGROUND: Measurements of extraocular muscle diameter may be useful in diagnosis and as an outcome indicator in the assessment of treatment options in thyroid-associated ophthalmopathy. Racial differences are known to account for craniofacial variations and orbital sizes. OBJECTIVE: To determine the normal diameters of extra-ocular muscles using computed tomography in a homogeneous, group of hospital patients in a tertiary hospital in Nigeria. MATERIAL AND METHOD: The maximum diameters of extra-ocular muscles were measured for 182 normal patients on thin slice reconstructed coronal computed tomography images. The effects of age and sex were determined. RESULT: Normal ranges for the diameters (mean + 2 SDs) of extraocular muscles were 4.5 + 1.2 mm for medial rectus, 4.9 + 2.1 mm for lateral rectus, 4.8 + 1.6 mm for inferior rectus and 4.0 + 1.5 mm for the superior group. The mean diameter of the extra-ocular muscles of male patients was not significantly larger than that of female patients (p > 0.05). There was a small but positive correlation between age and diameter of each extra-ocular muscle except in the left medial rectus and right lateral rectus muscles (P < 0.05). CONCLUSION: These normative values may serve as radiological reference values in the assessment of changes in size and suspected enlargement of the extraocular muscles in Nigerian patients. They may also be extrapolated to other Black African patients, until population studies become available.

ABSTRACT

BACKGROUND: Optic neuropathy is not a diagnosis in itself, as potential aetiologies are myriad. A pilot study conducted in the Eye Clinic, University College Hospital, Ibadan, between September 2007 and November 2009, showed that 46.8% of new cases presenting to the neuroophthalmology unit, had non-glaucomatous optic neuropathy (NGON) in which, the precise aetiology of optic neuropathy was never diagnosed. METHODS: All cases of NGON, seen in the neuro-ophthalmology unit, between September 2007 and June 2014 were analyzed to determine common aetiologies and identify the difficulties encountered in their investigation or management. RESULTS: There were 159 cases of NGON. The age range was 6 months to 87 years (mean 39.0, SD 21.3). Male: Female ratio was 1.2: 1, and the commonest diagnosis was optic atrophy of unknown aetiology. Challenges identified included difficulty obtaining recommended radiological and serological investigations, as well as no access to genetic studies and high loss to follow-up. CONCLUSION: There are major constraints in the investigation of patients presenting with optic nerve disease in Ibadan, despite the prevalence of NGON as a major cause of visual disability among neuro-ophthalmic patients in this setting. Diagnostic constraints must be addressed, to facilitate neuroophthalmology patient care, within our limited resources.

ABSTRACT

BACKGROUND: There is very limited literature on squamous papillomas of the conjunctiva from Nigeria and sub-Saharan Africa. In an attempt to contribute to the literature on the subject, we studied the clinicopathological characteristics of patients histologically diagnosed with squamous papilloma of the conjunctiva in Ibadan, Nigeria. MATERIALS AND METHODS: Clinical and pathological records of patients with histological diagnosis of squamous papilloma of the conjunctiva made in the Department of Pathology, University College Hospital, Ibadan, between January 1985 and December 2004, were reviewed. RESULTS: There were totally 26 cases. Patients' ages ranged from 2 to 58 years with a mean age of 32 years. Male to female ratio was 1.4:1. Size of tumors ranged from 2 to 10 mm. Duration of presenting complaints was from 2 months to 10 years. The lesions in 10 cases were located in the medial canthus, at or close to the limbus in another 10 cases, and in the tarsal conjunctiva in a single case. Five cases had no documentation of location. Sixteen cases (61.5%) had multiple papillomas. Four cases had a history of chemical injury (alkaline based - hair relaxer in a single case, acid based - wet cell car battery fluid in two cases, and unknown chemical in a single case) preceding the lesion by at least 6 weeks. Fourteen cases had koilocytosis on histology suggestive of Human Papilloma Virus (HPV) etiology. HIV screening test was negative in the three patients who had the screening done. Preoperative clinical diagnosis was squamous papilloma in 16 cases, pterygium in 6 cases and squamous cell carcinoma in 2 cases. CONCLUSION: In the environment where we practice, conjunctival squamous papilloma occurs most commonly in the fourth decade of life. Only very few cases are submitted for histological diagnosis. HPV infection and chemical injury are the main etiology. We strongly advocate that all excisions of the conjunctiva, irrespective of the clinical impression, should be submitted routinely for histological assessment.

ABSTRACT

Solitary fibrous tumor (SFT) of the orbit, initially thought to be rare, is being increasingly documented in the medical literature. We here present the case of a 37-year-old Nigerian man who presented with left sided painless, vision-sparing proptosis. Cranial computed tomography scan showed a globular, left medial, orbital extraconal mass. The mass was excised, en bloc, via a medial orbitotomy procedure aided by left ethmoidectomy. Surgery was uncomplicated and histology of the excised tissue was reported as compatible with SFT. There was also a strong and diffuse immunostaining with CD 34. At 6-month follow-up, the left-sided proptosis has completely regressed. To the best of our knowledge, this is the second case of orbital SFT to be reported in an African.

ABSTRACT

BACKGROUND: Early diagnosis of cancer allows an opportunity for timely treatment while disease burden is in its earliest stages. Unfortunately, late presentation and delayed diagnosis of childhood cancers remains a problem in developing countries. OBJECTIVES: To describe the pre-diagnostic symptomatic intervals and the factors influencing these time intervals in childhood cancer at the University College Hospital, Ibadan, Nigeria. METHODS: Information was obtained from the case notes of children seen between March 2006 and August 2008. Information included socio-demographic variables, stage of the cancer, duration of illness at diagnosis and other health seeking activities. RESULTS: Sixty-four children (40 males, 24 females) were studied. Median overall lag time was 13.1 weeks; median parent delay was 2 weeks and median health system delay was 8.8 weeks. Median lag times were shortest in acute leukaemia (8.1 weeks) and Wilms. tumour (8.7 weeks) and longest in Hodgkin lymphoma (101.7 weeks). CONCLUSION: Lag times were longer than those in developed countries. Factors contributing to delayed diagnosis included delayed referral by doctors, seeking health care from alternate sources and financial constraints. Education of parents and physicians on early presentation and early referral for early diagnosis is recommended.
