RESUMEN
PURPOSE: Breast cancer survivors are a distinct category of patients with unique characteristics and needs. The population of survivors is expected to increase, given the rising incidence of breast cancer in Nigeria, and the improvements in breast cancer outcomes. This study evaluated the clinicopathologic characteristics and the psychosocial experiences of a cohort of Nigerian breast cancer survivors. METHODS: From an institutional breast cancer database, patients managed between January 2010 and December 2016 were evaluated. Clinicopathologic characteristics, treatment details, and survival estimates were assessed. These were compared with nonsurvivors managed during the same period. Survivors were defined as those who have been alive for at least 5 years from the date of presentation. Qualitatively, a purposive sample of 20 survivors was evaluated using one-on-one in-depth interviews to assess their experiences and coping mechanisms after treatment. RESULTS: Of the 355 patients in the database during the study period, there were 163 survivors (45.9%), while 192 (54.1%) died. Age, stage at presentation, tumor size, and receipt of multiple treatment modalities were significantly associated with survival. Five themes were identified in qualitative analysis: initial reaction to the diagnosis, experiences during treatment, social support, coping strategies, and advocacy. Strong family support and spirituality were prominent coping strategies identified in this cohort. CONCLUSION: Despite obvious infrastructural and manpower limitations, Nigerian patients who present early and receive multimodal therapy and different breast cancer treatments have better odds of survival. Survivors have some unmet psychosocial and physical needs requiring intervention.

BACKGROUND: In Nigeria, breast cancer incidence is rising, late presentation is common, and outcomes are poor. Patient-related factors such as lack of awareness and misperceptions in addition to health system deficiencies such as lack of a clearly defined framework for breast cancer screening and referral are some of the major drivers of this poor outlook. Guidelines for breast cancer screening in high-income countries have limited applicability in low-middle-income countries, hence the need for innovative, resource-compatible strategies to combat the negative trend. This manuscript presents our study protocol which aims to evaluate the impact of a novel breast cancer early detection program developed to address delayed presentation and lack of access to diagnostic and treatment facilities in South-West Nigeria. This entails the use of mobile technology (innovative handheld iBreast Exam [iBE] device, mobile breast ultrasound, and mobile mammography) and patient navigation as interventions at the community level. METHODS: The study (ClinicalTrials.gov identifier: NCT05321823) will adopt a randomized two group clinical trial design with one local government area (LGA) serving as an intervention arm and another serving as the control. Both LGAs will receive breast cancer awareness education but only one will receive the interventions. In the intervention arm, asymptomatic (40-70 years) and symptomatic (30-70 years) women will be invited for breast evaluation which will be performed by trained Community Health Nurses using Clinical Breast Exam (CBE), and iBE. Those with positive findings will proceed to imaging using mobile mammography and ultrasound brought to the LGA every month. Symptomatic women with negative findings on CBE and iBE will be scheduled for repeat clinical evaluation on a short-term basis (one month). The Radiologist will obtain core needle biopsies as indicated and transfer them for prompt pathological assessment. Women presenting to the Primary Healthcare Centers in the control LGA will be referred directly to Obafemi Awolowo University Teaching Hospitals Complex as per the current standard of care. Records of all breast cancer cases seen in the two LGAs during the study period will be obtained. The program metrics will include screening participation rate, cancer detection rate, stage at diagnosis, and timeline from detection to initiation of treatment. The stage at diagnosis and timeline from detection to treatment compared between the two LGAs will be used to assess the impact of the intervention. The study is proposed for 2 years; however, a descriptive analysis will be carried out at 1.5 years to evaluate the retention of the study participants. STUDY SIGNIFICANCE: It is anticipated that this study will provide vital data to support wider breast cancer screening efforts in Nigeria.

Core needle biopsy is currently the most widely used basic diagnostic method for the diagnosis of breast masses; it is a minimally invasive procedure with excellent specificity and sensitivity and negligible complication rates, particularly when image-guided. However, complications tend to be higher when performed blindly. Hematoma remains the most common complication resulting from this procedure. Iatrogenic pseudoaneurysm is a rare complication with no previous report in Nigeria. In this report, we present a case of breast pseudoaneurysm occurring after 2 blind, palpation-guided core needle biopsies in a 51-year-old known hypertensive woman at a Nigerian tertiary hospital. Spontaneous thrombosis of the pseudoaneurysm occurred over three months after the second blind biopsy.
RESUMEN
Context: COVID-19 came suddenly, bringing to the fore the challenges inherent in the health system. In a developing country, such as Nigeria, which already had myriad problems with funds and equipment in the health sector. Aims: This study aims to examine the challenges encountered by the staff in Radiology facilities and how they combated the challenges. Settings and Design: A descriptive cross-sectional study of radiology facilities in Nigeria. Subjects and Methods: Radiologists from nine government and four private facilities who attended to COVID-19 patients were asked to fill questionnaires on challenges faced and their coping strategies. Responses were sent through E-mail. Statistical Analysis Used: Data from the responses were analyzed using Microsoft excel for Mac 2011 and presented as figures and tables. Results: Majority of the government 7 (77.8%) and private facilities 4 (100%) had no equipment dedicated only to COVID-19 patients. Seven (77.8%) government facilities complained of inadequate staff, poor availability of personal protective equipment (PPEs) 8 (88.9%), and lack of technology for remote viewing 7 (77.8%). Fear of cross-infection was a challenge in one of the facilities 1 (11.1%). Coping strategies adopted include ensuring less traffic in the department by discouraging walk-in patients and canceling non-emergent cases, booking suspected/confirmed cases for lighter times, using old film for face shields and cloth for facemasks, staff education on COVID-19 and preventive measures, and sending reports to physicians through E-mail. Conclusions: There were a lot of challenges during the COVID-19 crisis, with government hospitals experiencing more challenges than private facilities. The challenges included among others inadequate staff strength and lack of technology for remote viewing. Some were overcome using education and by production of facemasks/shields production using recycled materials.
RésuméLe contexte: COVID-19 came suddenly, bringing to the fore the challenges inherent in the health system. Dans un pays en développement, comme Le Nigeria, qui avait déjà une myriade de problèmes de fonds et d'équipements dans le secteur de la santé. Objectifs : Cette étude vise à examiner les défis rencontrés par le personnel des établissements de radiologie et comment ils ont relevé les défis. Paramètres et conception: une section descriptive étude des installations de radiologie au Nigeria. Sujets et méthodes: Radiologues de neuf établissements publics et de quatre établissements privés qui ont participé aux patients COVID-19 ont été invités à remplir des questionnaires sur les défis rencontrés et leurs stratégies d'adaptation. Les réponses ont été envoyées par courrier électronique. Analyse statistique utilisée: Les données des réponses ont été analysées à l'aide de Microsoft Excel pour Mac 2011 et présentées sous forme de figures et de tableaux. Résultats: La majorité des établissements publics 7 (77,8 %) et privés 4 (100 %) ne disposaient d'aucun équipement dédié uniquement aux patients COVID-19. Sept (77,8 %) établissements publics se sont plaints d'un personnel inadéquat, d'une faible disponibilité des équipements de protection individuelle (EPI) 8 (88,9 %), et le manque de technologie pour la visualisation à distance 7 (77,8 %). La peur d'une infection croisée était un défi dans l'un des établissements 1 (11,1 %). Faire faceles stratégies adoptées comprennent la réduction de la circulation dans le service en décourageant les patients sans rendez-vous et en annulant les cas non urgents, en réservant les cas suspects/confirmés pour des périodes plus légères, en utilisant un vieux film pour les écrans faciaux et un tissu pour les masques faciaux, la formation du personnel sur COVID-19 et mesures préventives et l'envoi de rapports aux médecins par courrier électronique. Conclusions: Il y a eu beaucoup de défis pendant la COVID-19 crise, les hôpitaux publics étant confrontés à plus de défis que les établissements privés. Les défis comprenaient entre autres l'insuffisance la force du personnel et le manque de technologie pour la visualisation à distance. Certains ont été surmontés grâce à l'éducation et à la production de masques faciaux/boucliers utilisant des matériaux recyclés. Mots-clés: défis, les stratégies d'adaptation, COVID-19, Nigeria.

BACKGROUND: Mammography, the most preferred tool for breast cancer screening, has very poor uptake in Nigeria, even among health workers. No nationwide study has been done to ascertain this. This study sought to determine the current perceptions and practices of Nigerian female health care practitioners on mammography screening across different types and levels of health care institutions in the country's 6 geopolitical zones. METHODS: This cross-sectional online survey was conducted using Google Forms distributed among Nigerian female health workers via online professional associations and networks. Descriptive and inferential statistics were done using SPSS version 20. RESULTS: A total of 562 respondents, with mean age of 41.30 ± 9.8 years, were surveyed. About half (50.3%) were doctors, with majority practicing in southern Nigeria. A mammography screening utilization rate of 15.4% was found, with majority having their first mammography long after attaining the age of eligibility. As of the time of the survey, only 24.8% of tertiary health workers had access to functional mammography machines at their place of work. Majority of female doctors (78%) never refer eligible patients for mammography, although nearly all (98.6%) were willing to do so. About 54% of those who have had a previous mammography screening vs. 17% who have not had 1 would recommend it to others. Majority of respondents recommended annual mammography from the age of forty at a subsidized cost. CONCLUSION: Nigerian female health workers have limited access to mammography and consequently do not screen often. Efforts must be made to make 'charity begin at home'.

BACKGROUND: This study aimed at evaluating the endoscopic management and clinical outcomes in patients with obstructive jaundice undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP) within a newly established apprenticeship teaching model at an academic centre in a resource-limited setting. MATERIALS AND METHODS: We employed an apprenticeship-style model of ERCP training with graded responsibility, multidisciplinary group feedback and short-interval repetition. We collected sociodemographic and clinicopathologic data on consecutive patients who underwent ERCP from March 2018 to February 2020. RESULTS: A total of 177 patients were referred, of which 146 patients had an ERCP performed for obstructive jaundice and 31 excluded during the study period. The median age was 55 years, age range from 8 to 83 years. The most common referral diagnosis was pancreatic head cancer 56/146 (38.1%), followed by choledocholithiasis 29/146 (19.7%), cholangiocarcinoma 22/146 (15.0%) and gall bladder cancer 11/146 (7.5%). In all, 102 patients had a malignant indication for ERCP. The cannulation rate was 92%. The most common site for malignant biliary obstruction was proximal bile stricture in 31/102 (30.4%), followed by distal bile strictures in 30/102 (28.4%), periampullary cancer 20/102 (19.6%) and mid bile duct stricture in 9/102 (8.8%). The common benign obstructive etiology includes choledocholithiasis in 33/44 (75%) and mid duct obstruction from post-cholecystectomy bile duct injury in 3/44 (2.9%) while 2/44 (2.0%) patients had choledochal cyst. Overall complications were post-ERCP pancreatitis (8/146 patients), cholangitis (3/146 patients), stent migration and post-sphincterotomy bleeding (one patient each). Peri-procedural mortality was 5/146 (3.4%). CONCLUSION: ERCP is an effective and safe method of treatment of patients with benign and malignant biliary obstruction. The low morbidity and mortality and its immediate therapeutic benefits, together with the short duration of hospitalization, indicate that this procedure is an important asset in the management of such patients.

BACKGROUND: The aim of this study is to compare the Achilles tendon (AT) thickness (ATT) and plantar fascia (PF) thickness (PFT) of diabetics with and without peripheral neuropathy (PN) to that of a control population. MATERIALS AND METHODS: B-mode sonography of the AT and PF was done. Correlation analysis was used to determine the relationship between ATT and PFT with demographic data such as body mass index, duration of diabetes, and presence of PN. A multivariate regression was used to construct models for determining the thicknesses. RESULTS: Eighty type 2 diabetics were recruited and categorized into groups based on the presence or absence of PN (Groups A and B, respectively). Group A constituted 57 participants while there were 23 in Group B. Eighty controls constituted Group C. Mean values of 6.08 ± 0.65, 5.08 ± 0.48, and 4.57 ± 0.57 mm (P < 0.001) of the right ATT were obtained in Groups A to C while values of 1.95 ± 0.35, 1.88 ± 0.39, and 1.44 ± 0.20 mm (P < 0.001) were obtained for the right PFT. CONCLUSION: The presence of PN and factors such as diabetes duration can affect the thickness of AT and PF.
RESUMEN
BACKGROUND: Neuropathy is a common complication of diabetes mellitus resulting from direct damage by hyperglycemia to the nerves and/or ischemia by microvascular injury to the endoneurial vessels which supply the nerves. Median nerve is one of the peripheral nerves commonly affected in diabetic neuropathy. The median nerve size has been studied in non-Nigerian diabetic populations. In attempt to contribute to existing literature, a study in a Nigerian population is needed. AIM: To evaluate the cross-sectional area (CSA) of the median nerve using B-mode ultrasonography (USS) and the presence of peripheral neuropathy (PN) in a cohort of adult diabetic Nigerians. METHODS: Demographic and anthropometric data of 85 adult diabetes mellitus (DM) and 85 age- and sex-matched apparently healthy control (HC) subjects were taken. A complete physical examination was performed on all study subjects to determine the presence of PN and modified Michigan Neuropathy Screening Instrument (MNSI) was used to grade its severity. Venous blood was taken from the study subjects for fasting lipid profile (FLP), fasting blood glucose (FBG) and glycated haemoglobin (HbA1c) while their MN CSA was evaluated at a point 5 cm proximal to (5cmCATL) and at the carpal tunnel (CATL) by high-resolution B-mode USS. Data was analysed using SPSS version 22. RESULTS: The mean MN CSA was significantly thicker in DM subjects compared to the HC at 5cmCATL (P < 0.01) and at the CATL (P < 0.01) on both sides. The presence of diabetic peripheral neuropathy (DPN) further increased the MN CSA at the CATL (P < 0.05) but not at 5cmCATL (P > 0.05). However, the severity of DPN had no additional effect on MN CSA 5 cm proximal to and at the CATL. There was no significant association between MN CSA and duration of DM and glycemic control. CONCLUSION: Thickening of the MN CSA at 5cmCATL and CATL is seen in DM. Presence of DPN is associated with worse thickening of the MN CSA at the CATL but not at 5cmCATL. Severity of DPN, duration of DM, and glycemic control had no additional effect on the MN CSA.
RESUMEN
OBJECTIVES: Studies have shown that common carotid intima media thickness (CIMT) measured by B-mode sonography increases with body mass index (BMI) among subjects with cardiovascular diseases in different populations. However, association of body fat and subclinical atherosclerosis in the absence of these cardiovascular diseases is understudied. We aimed to evaluate the correlation between BMI and CIMT in a healthy adult population of black African ancestry. METHODS: This is a cross-sectional prospective study in 300 consecutive apparently healthy subjects aged 18 to 70 years without history of hypertension, dyslipidemia, diabetes mellitus, and renal disease. Subjects' common carotid artery intima media thickness was measured with a 7.5-MHz linear ultrasound transducer at a point 10 mm proximal to the carotid bulb. All subjects' biodata, medical history, anthropometric (weight and height from which BMI was calculated), laboratory (fasting lipid profile and blood glucose), and CIMT values were recorded on a pro forma. Data were analysed using SPSS version 21, and significant P was set at less than .05. RESULTS: The right, left, and average CIMT of both sides in our study subjects are 0.52 ± 0.11 mm, 0.51 ± 0.11 mm and 0.52 ± 0.11 mm respectively, with no significant difference between the right and left sides (P > .05). The right, left, and average CIMT increased with increasing age and BMI category (all P < .01) but were not significantly different between men and women (all P > .05). Age (r = .824, .825, and .827; P < .01) and BMI (r = .503, .504, .507; P < .01) had strong positive correlations with right, left, and average CIMT. CONCLUSIONS: Increasing age and BMI category, but not sex, significantly influenced CIMT values in our apparently healthy black African population.

BACKGROUND: Metabolic risk factors associated with non-alcoholic fatty liver disease (NAFLD) include Type 2 diabetes mellitus (T2DM), obesity and dyslipidaemia. Prevention or management of these risk factors with glycaemic control, weight reduction and low serum lipid levels respectively have been reported to reduce the risk of NAFLD or slow its progression. Since ultrasound (USS) is a safe and reliable method of identifying fatty changes in the liver, this study was done to determine the relationship between glycaemic control and ultrasound diagnosed NAFLD in T2DM. METHODOLOGY: Demographic data, anthropometric measurements and laboratory tests including glycated haemoglobin (HbA1c), fasting blood glucose (FBG) and serum lipids of 80 T2DM subjects aged 40-80 years were taken. Their livers were evaluated using B-mode ultrasound, and the data obtained were statistically analysed using SPSS version 20. RESULTS: Fifty-five of all participants (68.8%) were diagnosed with NAFLD sonographic grades 1, 2 and 3 made up of 13 (16.3%), 26 (32.5%) and 16 (20.0%), respectively while 25 (37.2%) had grade 0. The prevalence of NAFLD in T2DM varied significantly with BMI (p = 0.001) and glycaemic control (p = 0.048) while the USS grades of NAFLD varied significantly with age (p = 0.043) and BMI (p = 0.006). The independent strong predictors of NAFLD were overweight (r = 0.409, p = 0.012, OR = 6.626) and obesity (r = 0.411 p = 0.009, OR = 11.508), while poor glycaemic control (r = 0.270, p = 0.015, OR = 3.473) was a moderate independent predictor. CONCLUSION: The prevalence of NAFLD increases with increasing BMI and HBA1c in T2DM, while its ultrasound grade varies with BMI. Overweight, obesity and poor glycaemic control are independent predictors of NAFLD.

BACKGROUND: Traditional cardiovascular risk factors (CVRFs), which include age, gender, hypertension, diabetes mellitus, dyslipidaemia, smoking, alcohol consumption, chronic kidney disease and obesity, have been shown to be associated with atherosclerosis. We aimed to evaluate the impact of traditional CVRFs on carotid atherosclerosis (CA) in a sample of Nigerian adults. METHODS: We examined 162 subjects with traditional CVRFs in a cross-sectional study. Demographic and clinical data, including history of hypertension, diabetes mellitus, smoking, alcohol intake and chronic kidney disease, as well as systolic and diastolic blood pressure, weight and height were collected. Serum creatinine, fasting blood glucose and lipid profiles were also determined. Carotid intima-media thickness (CIMT) and presence of carotid plaque (CP) were evaluated by high-frequency B-mode ultrasound. Chi-squared and regression analyses were carried out to determine associations between variables of CIMT and CVRF. RESULTS: Increased CIMT was associated with all CVRFs (p < 0.05) except gender (p > 0.05), while CP was associated with older age, obesity, hypertension and dyslipidaemia (p < 0.05). We found prevalence of increased CIMT was 53.7%, while that of CP was 16.1%. The prevalence of CA (increased CIMT and CP) also increased with increasing number of CVRFs in the subjects. Age ≥ 50 years, hypertension, dyslipidaemia, obesity and alcohol intake explained 78.7% of variance in CIMT, while age ≥ 50 years and hypertension explained 38.0% of variance in CP. CONCLUSIONS: CA was associated with presence and increasing number of traditional CVRFs. A significant percentage of variance in CA was, however, unexplained by traditional CVRFs.

OBJECTIVES: Brachial artery flow-mediated dilatation on sonography is used to evaluate endothelial dysfunction, which is a key event in the development of atherosclerosis and predates structural atherosclerotic lesions by many years. Atherosclerosis has been implicated in the pathophysiologic mechanisms of ischemic stroke. The aim of this study was to determine the association between brachial flow-mediated dilatation, the presence of cardiovascular risk factors, and acute stroke. METHODS: We evaluated right brachial arteries of 150 participants (50 stroke patients, 50 patients with cardiovascular risk factors, and 50 healthy control individuals) with B-mode sonography before and 5 minutes after sphygmomanometer cuff application to their forearms. Analysis of variance for multiple comparisons was used between each group. RESULTS: Mean ages of the stroke, risk factor, and control groups ± SD were 57.5 ± 14.8, 52.4 ± 16.0, and 56.1 ± 14.9 years, respectively (P = .235). Flow-mediated dilatation rates were 4.37% ± 1.50%, 5.62% ± 1.23%, and 10.33% ± 1.96% in the stroke, risk factor, and control groups (P ≤ .001). Dilatation was 3.79% ± 0.92% in ischemic stroke compared with 6.02% ± 1.62% in intracerebral hemorrhage (P < .001), but there was no significant difference in dilatation between ischemic stroke subtypes according to the Trial of ORG 10172 in Acute Stroke Treatment classification (P = .301). CONCLUSIONS: Brachial flow-mediated dilatation was significantly lower in patients with acute stroke compared with controls matched for vascular risk factors and healthy controls. Decreased vascular endothelial function in stroke patients was particularly related to cerebral infarction compared with intracerebral hemorrhage. Brachial flow-mediated dilatation did not differentiate ischemic stroke subtypes by the Trial of ORG 10172 in Acute Stroke Treatment classification. Flow-mediated dilatation was therefore found to be a marker of cardiovascular risk and a probable reactant in the acute phase of stroke.
