Coverage and Socioeconomic Inequalities in Cervical Cancer Screening in Low- and Middle-Income Countries Between 2010 and 2019.

PURPOSE: Cervical cancer screening is vital in addressing the global burden of cervical cancer. In this study, we describe the coverage and socioeconomic inequalities in the coverage of cervical cancer screening in low- and middle-income countries (LMICs). METHODS: We analyzed data from the women's recode files of the Demographic and Health Surveys conducted in LMICs from 2010 to 2019 with variables on cervical cancer screening. We included women 21 years or older and determined the proportion of women who were screened for cervical cancer by age categories, wealth quintile, type of place of residence, level of education, and marital status. Socioeconomic inequality was measured using the concentration index (CIX) and the slope index of inequality (SII). RESULTS: A total of 269,506 women from 20 surveys in 16 countries were included in the survey. Generally, there was a low coverage of screening, with lower rates among women age 21-24 years, living in rural areas, in the poorest wealth quintile, with no formal education, and who have never been in union with or lived with a man. The CIX and SII values for screening for cervical cancer were positive (pro-rich) for all the countries except Tajikistan in 2012 where they were negative (pro-poor). CONCLUSION: The coverage of cervical cancer screening was low in LMICs with variations by the quintile of wealth (pro-rich) and type of place of residence (pro-urban). To achieve the desired impact of cervical cancer screening services in LMICs, the coverage of cervical cancer screening programs must include women irrespective of the type of place and wealth quintiles.

Determinants of caregiver's knowledge and practices regarding childhood fever management in a developing setting: a multi-centre cross-sectional assessment.

Introduction: Fever is both a sign of various diseases (chief of which are infectious in nature) and an adverse effect of certain interventions (e.g. vaccines, drugs) in the pediatric population. It elicits anxiety among caregivers and healthcare professionals alike resulting in non-evidence based practices, adverse medication administration events, waste of scarce resources and overutilization of health facilities. The determinants of these practices among caregivers in the domiciliary contexts have not been well characterized in developing settings. Methods: We assessed the knowledge and practices of childhood fever and their determinants among caregivers in domiciliary settings in Northern Nigeria using a 41-item questionnaire between August 2020 and February 2021. Results: The questionnaire is reliable (knowledge: Cronbach's Alpha = 0.689; practice: Cronbach's Alpha = 0.814) and collected data on a total of 2,400 caregiver-child pairs, who participated in the study. Over two-third (68.3%; 1,640) of the caregivers expressed fever phobic tendencies. Paracetamol was the most commonly used medication and constituted 31.3% of medication administration adverse events reported by the caregivers. Only one out of every six knowledgeable caregivers engaged in evidence-based home childhood fever management practices (7% vs. 41.6%) with being a primary caregiver [Knowledge: odd ratio (OR): 2.81, 95% CI: 0.38; 5.68; p value: 0.04; Practice: OR: 1.65, 95% CI: 0.09; 7.33; 0.02] and having a child/children aged ≤3 years (knowledge: OR: 7.03, 95% CI: 4.89; 9.67, p value: 0.003; practice OR: 3.11, 95% CI: 1.27; 8.59, 0.007) determining both the knowledge and practices of childhood fever management in a household. Conclusions: The knowledge and practice of childhood fever management among caregivers were sub-optimal with being a primary caregiver and having a child/children aged ≤3 years being the significant determinants of each domain. These gaps underscore the dire need for targeted strategies aimed at improving childhood fever management by educating caregivers.

Socioeconomic inequalities in prostate cancer screening in low- and middle-income countries: An analysis of the demographic and health surveys between 2010 and 2019.

INTRODUCTION: Prostate cancer screening is a valuable public health tool in the early detection of prostate cancer. In this study, we aimed to determine the socioeconomic inequalities in the coverage of prostate cancer screening in Low and Middle-Income Countries (LMICs). METHODS: This was a retrospective analysis of men's recode data files that were collected by the Demographic and Health Surveys (DHS) in LMICs (Armenia, Colombia, Honduras, Kenya, Namibia, Dominican Republic, and the Philippines). We included surveys that were conducted from 2010 to 2020 and measured the coverage of prostate cancer screening and the study population was men aged 40 years or older. Socioeconomic inequality was measured using the Concertation Index (CIX) and the Slope Index of Inequality (SII). RESULTS: Eight surveys from seven countries were included in the study with a total of 47,863 men. The coverage of prostate cancer screening was below 50% in all the countries with lower rates in the rural areas compared to the urban areas. The pooled estimate for the coverage of screening was 10.4% [95% CI, 7.9-12.9%). Inequalities in the coverage of prostate cancer screening between the wealth quintiles were observed in the Democratic Republic, Honduras, and Namibia. Great variation in inequalities in the coverage of prostate cancer screening between rural and urban residents was observed in Colombia and Namibia. CONCLUSION: The coverage of prostate cancer screening was low in LMICs with variations in the coverage by the quintile of wealth (pro-rich) and type of place of residence (pro-urban). POLICY SUMMARY: To achieve the desired impact of prostate cancer screening services in LMICs, it is important that the coverage of screening programs targets men living in rural areas and those in low wealth quintiles.

The efficacy of magnesium sulphate as an adjunct to local anaesthetics for perineal pain relief after episiotomy.

BACKGROUND: Episiotomy is a deliberate surgical incision of the perineum with the aim of increasing the vulval outlet to facilitate childbirth. However, it could be associated with some complications, such as pain, hemorrhage, and wound infection. It is a surgical procedure that requires adherence to basic surgical principles of providing adequate analgesia. AIM: To determine the efficacy of magnesium sulphate (MgSO4) as an adjunct to local anesthetics for analgesia during episiotomy repair among women that had vaginal delivery at Usmanu Danfodiyo University Teaching Hospital Sokoto, Sokoto, Nigeria. SUBJECT AND METHODS: This was a single-blind randomized clinical trial. Pregnant women who had episiotomy during the study period were randomized into two groups. Those in Group A had xylocaine administered alone, whereas those in Group B had xylocaine + MgSO4 administered for repair of episiotomy. Pain was assessed by numeric rating scale at commencement of the repair, at 2 and 6 h after the repair. Patient's level of satisfaction, request for additional analgesia, and side effects were also assessed. RESULTS: The pain score in the xylocaine + MgSO4 group was lower throughout the period of assessment. There was no significant difference in the pain scores between the two groups at 0 and 6 h. However, there was significant difference in the mean pain scores between the two groups at 2 h (P < 0.001). There was no significant difference in the level of satisfaction, request for additional analgesia, and side effects between the two groups. CONCLUSION: Both xylocaine alone and xylocaine with MgSO4 provide adequate perineal pain relief during episiotomy repair. MgSO4 improves the analgesic effect of xylocaine at 2 h after episiotomy repair without any significant side effect.

Prevalence and outcome of increased nuchal translucency in usmanu danfodiyo university teaching hospital, Sokoto, Nigeria: A cohort study.

BACKGROUND: An important component of the first-trimester scan is nuchal translucency thickness at 11 weeks to 13 weeks 6 days of gestation. A nuchal translucency ≥3.3 mm is a significant early pregnancy scan finding associated with Trisomies 13, 18, and 21 and congenital heart diseases. AIMS: To determine the prevalence and outcome of increased fetal nuchal translucency among pregnant women. SUBJECTS AND METHODS: A prospective cohort study at the Obstetrics and Gynaecology Department of Usmanu Danfodiyo University Teaching Hospital Sokoto. This was a prospective study of 265 consecutively recruited women in the first trimester of pregnancy who presented to antenatal clinics over a 20-week period. An NT scan was conducted at 11 weeks to 13 weeks 6 days followed by an anomaly scan at 18-22 weeks. Patients were followed up to delivery and 6-week post-partum. The neonates were examined at delivery and at 6-week postnatal life. Data entry and analysis was done with IBM SPSS version 20. The level of significance was set at less than 0.05. Frequency distribution; student t-test and Chi-squared test. RESULTS: The 95th percentile NT was 3.3 mm and the prevalence of increased NT above 3.3 mm was 3%. The mean maternal age of the participants was 28.1 ± 5.1 years and the modal parity was Para 0. The most common anomalies associated with increased NT were ventricular septal defect and spina bifida. A congenital anomaly was significantly associated with increased NT (P < 0.001). CONCLUSIONS: The prevalence of increased fetal nuchal translucency is relatively high in our environment and is associated with congenital fetal defects. Routine screening with first-trimester ultrasound will help detect congenital anomalies early.

Distal arthrogryposis type 5 and PIEZO2 novel variant in a Canadian family.

The group of distal arthrogryposis (DA) disorders is characterized by congenital contractures of the distal joints. In most instances, these are genetic disorders are inherited in an autosomal dominant fashion; however, there is wide genetic and phenotypic spectrum. Distal arthrogryposis type 5 (DA5) is clinically characterized by short stature, deep-set eyes, ptosis, ophthalmoplegia, triangular facies, restrictive pulmonary function, and "firm" muscles. DA5 is produced by a gain-of-function mutations in PIEZO2 gene, encoding for an ion-channel required to convert mechanical stimulus to biological signals in mammals essential to proprioception. Heterozygous mutations in PIEZO2 may lead to other phenotypes like Gordon Syndrome and Marden Walker syndrome. In this report, we present a 3-generation family affected with DA5, who all carry a variant of unknown clinical significance c.8068A>C (p.Ser2690Arg) in the PIEZO2 gene. DA5 is a very rare condition with less than 20 cases previously reported. Our report expands the phenotype and contributes to evidence of this variant's pathogenicity.

Repair of ascending aortic pseudoaneurysm eroding through the sternum.

In reoperation for an ascending aortic pseudoaneurysm eroding through the sternum, a left ventricular vent allows careful unhurried sternal division under deep hypothermic circulatory arrest. We repaired ascending aortic pseudoaneurysms in 2 patients who had undergone aortic valve implantation 6 and 21 months earlier. A minithoracotomy was made in the left 5th intercostal space, and a vent was placed in the left ventricular apex. Repair was accomplished with a bovine pericardial patch reinforced with a Teflon felt strip. Both patients made an uneventful recovery with good functional status at discharge at the 8- and 18-month follow-up.

Functional dyspepsia is associated with duodenal eosinophilia in an Australian paediatric cohort.

BACKGROUND: The pathophysiology of functional dyspepsia (FD) remains unknown. Duodenal eosinophil infiltration has been reported. AIM: To assess the association between dyspeptic symptoms and duodenal eosinophilia in children undergoing upper gastrointestinal endoscopy. METHODS: In this retrospective cohort study, children with normal upper endoscopy and routine histology at a single tertiary paediatric centre between 2010 and 2014 were included. FD was defined as epigastric pain or discomfort >2 months without response to acid suppression. Controls presented with nonerosive reflux disease, dysphagia or rumination syndrome. Intramucosal eosinophil counts were compared between the groups using uni- and multivariate regression analyses. RESULTS: Thirty-six cases and 36 nonmatched controls were identified. Atopic history (39% vs. 25%) and psychological comorbidity (53% vs. 39%; both P = 0.2) were frequent in cases and controls. Self-reported nausea (64% vs. 17%; P < 0.0001), lethargy (19% vs. 0%; P = 0.005) and family functional gastrointestinal disorder(FGID) (28% vs. 3%; P = 0.003) were more common in cases than controls. Duodenal eosinophil counts [median (IQR): 151 (118-207) vs. 76 (60-106) per mm2 ; P < 0.001] were significantly higher in cases than controls with >112 eosinophils per mm2 predictive for FD (OR: 33.6, 95% CI: 7.1-159.0; P < 0.001). Duodenal eosinophilia was associated with weight loss (OR: 7.1, 95% CI: 1.1-45.5; P = 0.04). CONCLUSIONS: Functional dyspepsia in children is strongly associated with duodenal eosinophilia, in the absence of endoscopic or routine histological findings. Frequent atopic and psychological comorbidity illustrate likely multifactorial mechanisms.

Dissecting aneurysm of the interventricular septum due to rupture of the sinus of Valsalva.

Aneurysm of the sinus of Valsalva is a rare congenital cardiac anomaly. It occurs as an outpouching that progresses like a windsock, and it may rupture producing aortic regurgitation, cardiac tamponade, congestive heart failure, conduction abnormalities, and stroke. We describe a case of rupture of the sinus of Valsalva into the interventricular septum producing a large dissecting aneurysm. Despite the location, it did not produce a conduction abnormality.

Comminution of ibuprofen to produce nano-particles for rapid dissolution.

A critical problem associated with poorly soluble drugs is low and variable bioavailability derived from slow dissolution and erratic absorption. The preparation of nano-formulations has been identified as an approach to enhance the rate and extent of drug absorption for compounds demonstrating limited aqueous solubility. A new technology for the production of nano-particles using high speed, high efficiency processes that can rapidly generate nano-particles with rapid dissolution rate has been developed. Size reduction of a low melting ductile model compound was achieved in periods less than 1h. Particle size reduction of ibuprofen using this methodology resulted in production of crystalline particles with average diameter of approximately 270nm. Physical stability studies showed that the nano-suspension remained homogeneous with slight increases in mean particle size, when stored at room temperature and under refrigerated storage conditions 2-8°C for up to 2 days. Powder containing crystalline drug was prepared by spray-drying ibuprofen nano-suspensions with mannitol dissolved in the aqueous phase. Dissolution studies showed similar release rates for the nano-suspension and powder which were markedly improved compared to a commercially available drug product. Ibuprofen nano-particles could be produced rapidly with smaller sizes achieved at higher suspension concentrations. Particles produced in water with stabilisers demonstrated greatest physical stability, whilst rapid dissolution was observed for the nano-particles isolated in powder form.

Blalock-Taussig shunt: experience from the developing world.

BACKGROUND: Palliative procedures have a role in congenital cardiac malformations that do not permit a complete early repair, and in centres where facilities for complete early repair do not exist. The lack of data on modified Blalock-Taussig shunt from developing countries prompted this analysis. METHODS: We report a retrospective study of 70 Blalock-Taussig shunt procedures in 63 patients over an 8-year period. Most of the procedures (54.0%) were done on children less than 4 months of age. Thirty-nine (58%) patients had Tetralogy of Fallot; the remaining patients had a wide spectrum of lesions. RESULTS: In the first year of the review period, the classical Blalock-Taussig shunt was done in six patients (9.5%) and the modified Blalock-Taussig shunt was used thereafter. In 49 patients who were followed up long term, clinical congestive cardiac failure developed in three (6%) and shunt failure was reported in 10 (14%). Of the 16 (33%) total deaths, six had serious comorbid conditions preoperatively. CONCLUSIONS: The Blalock-Taussig shunt is a relatively safe palliative procedure, requiring fewer resources and less expertise than corrective surgery, making it a suitable option in developing countries.

Typhoid thyroiditis.

Acute suppurative thyroiditis in a 62 year old lady with enteric fever is reported. Plain radiography of the neck showed a distinct localised abscess cavity with air fluid level. A rare causative agent Salmonella typhi was isolated. Needle aspiration and antibiotics resulted in complete recovery.

Radiation doses to patient's relatives following radioiodine therapy.

A total of 10 volunteers were monitored for radiation doses, whose spouses were given radio-iodine (131I) orally. Nine of the spouses were given radio-iodine for Graves' disease and one for thyroid carcinoma. It was found that the highest radiation dose received by the volunteer was only 13.5% of the annual dose limit for individual members of the public. Hence, patients treated with radio-iodine do not pose a significant radiation hazard to the public.
