Aim: The present study aimed to evaluate the Plasmodium falciparum genetic diversity according to the host hemoglobin and G6PD genetic variants during the course of malaria in infected children aged from 2 to 10 years and living in endemic area in Burkina Faso. Study Design: The study was designed as a longitudinal follow up conducted between May 2015 and February 2016 in Banfora health district, Burkina Faso. Methodology: We included 136 subjects (73 males and 63 females; age range from 2-10 years). Blood thick and thin film was done by capillary blood. Venous blood was collected for DNA extraction. Malaria diagnosis was done by microscopy. Human and parasite DNA were extracted based on Qiagen kit procedure. Then, hemoglobin and G6PD were genotyped by RLFP-PCR while the msp1, msp2 and eba175 genes were typed by a nested PCR. All PCR products were analyzed by electrophoresis on a 1.5-2% agarose gel and alleles categorized according to the molecular weight. Results: The prevalence of hemoglobin type was 19.11% for abnormal hemoglobin and 80.9% for normal hemoglobin carriage. The prevalence of G6PD type was 91.18% for normal and 8.82% for G6PD deficiency carriage, respectively. The prevalence of msp1 allelic families was 81.60%, 80.80% and 67.20% for k1, ro33 and mad20 respectively while for msp2 gene, fc27 and 3D7 allelic family the prevalence was 70.53% and 69.64% respectively. The eba175 allelic families’ distribution showed 77.31% and 40.21% for fcr3 and Camp respectively. There was no difference in multiplicity of infection (MOI) according to hemoglobin genotypes and G6PD types. We found that k1 was the predominant allelic family of msp1 in normal hemoglobin genotype (AA) and normal G6PD type. The mixed infection of eba175 was statistically higher in abnormal hemoglobin (p=0.04). There was no statistical difference between fcr3 and camp prevalence excepted in G6PD deficient type. The polymorphism results showed that the prevalence of 450 bp in fc27 was statistically significantly higher in normal hemoglobin variant carriers (AA) than abnormal hemoglobin carriers (p=2.10 -4)). However, the prevalence of 350 bp in fc27 was statistically higher in normal G6PD than deficient G6PD carriers (p=0.034). Conclusion: Our result showed that the distribution of msp1 and eba75 polymorphism could be influenced by hemoglobin and G6PD variants. These results suggest that hemoglobin and G6PD could influence P. falciparum genetic diversity.

Introduction: Despite a significant decline in Senegal, malaria remains a burden in various parts of the country. Assessment of multiplicity of Plasmodium falciparum infection and genetic diversity of parasites population could help in monitoring of malaria control.Objective: To assess genetic diversity and multiplicity of infection in P. falciparum isolates from three areas in Senegal with different malaria transmissions. Methods: 136 blood samples were collected from patients with uncomplicated P. falciparum malaria in Pikine, Kedougou and Thies. Polymorphic loci of msp1 and 2 (Merozoite surface protein-1 and 2) genes were amplified by nested PCR.Results: For msp1gene, K1 allelic family was predominant with frequency of 71%. Concerning msp2 gene, IC3D7 allelic family was the most represented with frequency of 83%. Multiclonal isolates found were 36% and 31% for msp1et msp2 genes respectively. The MOI found in all areas was 2.56 and was statistically different between areas (P=0.024). Low to intermediate genetic diversity were found with heterozygosity range (He=0,394-0,637) and low genetic differentiation (Fst msp1= 0.011; Fst msp2= 0.017) were observed between P. falciparum population within the country.Conclusion: Low to moderate genetic diversity of P.falciparum strains and MOI disparities were found in Senegal.Keywords: Senegal, MOI, Genetic diversity, msp1, msp2.

Abstract Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.

Road Crashes

AbstractIn this commentary, we present a follow-up of two articles published in 2017 and 2018 about road traffic crashes, which is an important public health issue in Africa and Burkina Faso. The first article reported on a research project, conducted in partnership with local actors involved in road safety, carried out in Ouagadougou in 2015. Its aim was to test the effectiveness, acceptability, and capacity of a surveillance system to assess the number of road traffic crashes and their consequences on the health of crash victims. Several knowledge translation activities were carried out to maximize its impact and were reported in the 2018 article published in HRPS: monthly reports presenting the research data, large-format printed maps distributed to the city’s police stations, and a deliberative workshop held at the end of the research project. The present commentary presents our efforts to deepen our understanding of the impacts of the knowledge translation strategy, based on follow-up interviews, 18 months after the workshop, with the heads of the road traffic crash units in Ouagadougou police stations (n = 5). Several benefits were reported by respondents. Their involvement in the process prompted them to broaden their knowledge of other ways of dealing with the issue of road crashes. This led them, sometimes with their colleagues, to intervene differently: more rapid response at collision sites, increased surveillance of dangerous intersections, user awareness-raising on the importance of the highway code, etc. However, sustaining these actions over the longer term has proven difficult. Several lessons were derived from this experience, regarding the importance of producing useful and locally applicable research data, of ensuring the acceptability of the technologies used for data collection, of using collaborative approaches in research and knowledge translation, of ensuring the visibility of actions undertaken by actors in the field, and of involving decision-makers in the research process to maximize its impacts.

Abstract Background This study aims to compare the graft uptake rate and hearing improvement of fat graft versus inlay butterfly tragal cartilage in the repair of perforations in chronic otitis media mucosal in adults. In this retrospective study, twenty-eight patients were included with small dry anteroinferior tympanic membrane perforations (less than 1/3 of the tympanic membrane). The age range was 18 to 44 years old. Myringoplasty was done under general anesthesia for 8 patients with a fat graft (FG) and 20 patients with inlay butterfly cartilage graft (IBCG). Six months postoperatively, a follow-up evaluation was done for successful graft uptake and hearing outcomes. Results The success rate of graft uptake in the first group (fat graft) was 6/8 cases (75%) while in the second group (IBCG) was 19/20 (95%) with no statistically significant difference (P = 0.0148). Also, there was no statistical difference between the two groups as regards postoperative ABG, improvement changes in ABG, and number of patients with improved hearing. Conclusions Inlay butterfly cartilage graft is a useful graft in repairing small tympanic membrane perforations as regard graft take and hearing outcomes.

Exudation Rate

Object Chronic subdural hematomas (SDHs) are a local inflammatory process that causes the formation of a granulation tissue often referred to as the external or outer membrane. This membrane has abnormally permeable macrocapillaries. Therefore, exudation from the macrocapillaries in the outer membrane of chronic SDH may play an important role in the enlargement of chronic SDH. In this study the authors investigated the role of exudation in chronic SDH. Methods The authors examined 24 patients (16 men and eight women; age range 38–86 years [mean age 61.4 years]) with 27 chronic SDHs. The clinical status of the patients was evaluated according to the classification described by Markwalder. The diagnosis was established on computed tomography (CT) scans in all cases. The authors also used the Nomura Classification for judging the lesion's appearance on CT scans. Immediately after the diagnosis, all patients were administered 20 mCi (740 mBq) technetium-99m human serum albumin. Four hours later, blood and SDH samples were taken and radioactivity levels were measured in each. The ratio of activity of the samples taken from chronic SDH to the radioactivity of blood was determined as a percentage and defined as the exudation rate. On the follow-up CT scan obtained on postoperative Day 20, subdural collections thicker than 5 mm were determined to be a reaccumulation. Results The correlations between the exudation rate and age of the patients, clinical grades, CT appearances, and amount of reaccumulation were investigated. In this series the average exudation rate was 13.24% (range 2.05–28.88%). The mean exudation rates according to the clinical grades assigned to patients were as follows: Grade 0, 8.67 ± 5.64% (three patients); Grade 1, 5.07 ± 1.43% (eight patients); Grade 2, 17.87 ± 3.73% (seven patients); and Grade 3, 19.65 ± 7.67% (six patients). Exudation rates in patients with Grades 2 and 3 were significantly higher than those in Grades 0 and 1 (p < 0.05). The mean exudation rates according to the lesion's appearance on CT scans were found as follows: hypodense appearance, 6.55 ± 4.52% (eight patients); isodense appearance, 11.07 ± 6.32% (five patients); hyperdense appearance, 19.47 ± 13.61% (three patients); and mixed-density appearance, 17.40 ± 5.80% (nine patients). The differences among the groups were significant (p < 0.05). The average exudation rate was statistically higher in the patients with reaccumulation (16.30 ± 8.16%) than that in the patients without reaccumulation (9.96 ± 6.84%) (p < 0.05). Conclusions The exudation rate in chronic SDH is correlated with a higher clinical grade (Markwalder Grade 2 or 3), mixed-density CT appearance, and reaccumulation. Therefore, exudation from macrocapillaries in the outer membrane of chronic SDH probably plays an important role in the pathophysiology and the growth of chronic SDH.

BACKGROUND: The therapeutic response to endobronchial tuberculosis is usually evaluated by bronchoscopy. Currently, there are no published studies investigating the use of computed tomography for the evaluation of therapeutic response in endobronchial tuberculosis.OBJECTIVE: A retrospective study was performed to evaluate the bronchoscopic and computed tomographic features of endobronchial tuberculosis before and after treatment. The aim of this study was to investigate the usefulness of computed tomography for the assessment of treatment.METHODS: The clinical, pathological and bronchoscopic features of endobronchial tuberculosis were evaluated in 55 patients. The age range of the patients was 21 to 52 years. Computed tomography and bronchoscopy were performed before and after treatment.RESULTS: Diagnosis of tuberculosis was confirmed by culture and histopathological examination. Bronchoscopic examination revealed 89 endobronchial lesions of various types in 55 patients. The exudative type was the most common. Follow-up bronchoscopy revealed that exudative-, ulcerative- and granular-type lesions healed completely. Computed tomography performed after treatment correlated well with the follow-up bronchoscopic findings.CONCLUSION: The results suggest that follow-up computed tomography is useful for the evaluation of therapeutic response and complications associated with endobronchial tuberculosis, and may replace bronchoscopy.

AIM: To evaluate the effectivity of the combination of intracameral moxifloxacin 0.1% with subconjunctival triamcinolone acetonide 4 mg as prophylaxis of infection and inflammation after phacoemulsification in comparison with topical medication treated group. METHODS: A total one thousand patients with age range from 38 to 70 years old who scheduled for phacoemulsification were divided into 2 groups of no statistically significant differences in age, preoperative intraocular pressure (IOP) and central macular thickness (CMT), P=0.6, 0.9 and 0.8 respectively. The surgeries were done by 2 surgeons each one planned to use one method of prophylaxis at Eye Speciality Private hospital, Baghdad, Iraq. For the 1st group of patients (500) a topical moxifloxacin hydrochloride 0.5% and dexamethasone 0.1% eye drops were prescribed four times a day for 1mo postoperatively. For the 2nd group intracameral (IC) diluted moxifloxacin at 0.1% with subconjunctival (SC) triamcinolone 4mg in 0.4 cc were administered at the conclusion of the surgery. Follow up visits were on the first postoperative day, 1wk, 1mo, and 3mo postoperatively. Anterior chamber (AC) reaction was examined during the 4 visits while IOP was measured during the last 3 and CMT was measured only in the last one. RESULTS: The current clinical trial study compared 2 samples with 2 different prophylaxis methods. No endophthalmitis case reported in both group. By a 2-Sample t-test, the IC-treated group (group 2) had statistically significant lower AC cells at the 1st day postoperative visit than the other group while there were no statistically significant differences at 1wk, 1 mo and 3mo visits between the 2 groups. There was no statistically significant difference at 3mo visits in IOP and CMT between the two groups. A breakthrough inflammation rate with the topical medication was (9.6%) while in the other group (IC treated ) was 4.0%. A significant IOP elevation ≥10 mm Hg at 1mo in 2.4% within the topical medication group which was higher than the rate in the other group (0.8%). CONCLUSION: In addition to the safety and effectivity of the combination of intracameral moxifloxacin and subconjunctival triamcinolone in preventing infection and inflammation after cataract surgery. The majority (480) of our included patients didn’t require any topical postoperative medication that is cost saving for the patient, helped patients who were unable to administer topical medication, and decreased chance of complication related to patient poor adherence to postoperative medication.

Eight pediatric cardiac centers pooled clinical and ECG data from 372 patients who survived the Mustard operation (intraatrial baffle directing pulmonary venous blood to the tricuspid orifice and systemic venous blood to the mitral orifice) for at least 3 months. The follow-up period ranged from 0.4 to 15.9 years, and the mean age at operation was 2 years. The mean resting heart rate for patients who had the Mustard operation was consistently lower than age-matched controls. During the year of operation, 76% of patients had normal sinus rhythm; this percentage declined yearly to 57% by the end of the eighth postoperative year. Active arrhythmias increased after the tenth year. Second or third-degree heart block occurred in 33% of patients during the year of operation and changed very little thereafter. Of the total 372 patients, 39 received pacemakers, 52% during the year of surgery and 48% evenly distributed throughout the follow-up period.

Surgical Clinic

Introduction In 2013 our hospital introduced an in-hours, consultant-led, outpatient acute surgical clinic (ASC) for emergency general surgical patients. In 2014 this clinic was equipped with a dedicated ultrasonography service. This prospective cohort study evaluated this service before and after the introduction of ultrasonography facilities. Methods Data were recorded prospectively for all patients attending the clinic during 2013 and 2014. The primary outcome was patient destination (whether there was follow-up/admission) after clinic attendance. Results The ASC reviewed patients with a wide age range and array of general surgical complaints. In 2013, 186 patients attended the ASC. After the introduction of the ultrasonography service in 2014, 304 patients attended. In 2014, there was a reduction in the proportion of patients admitted to hospital from the clinic (18.3% vs 8.9%, p=0.002). However, the proportion of patients discharged after ASC review remained comparable with 2013 (30.1% in 2013 vs 38.8% in 2014, p=0.051). The proportion of patients undergoing computed tomography (CT) scans also fell (14.0% vs 4.9%, p<0.001). Conclusions The ASC assessed a wide array of general surgical complaints. Only a small proportion required hospital admission. The introduction of an ultrasonography service was associated with a further reduction in admission rates and computed tomography.

Dural arteriovenous fistulas (DAVF) associated with our series of patients with vein of Galen malformations (VOGM) are analyzed and discussed. We retrospectively analyzed 87 consecutive cases of VOGM treated between May 2002 and December 2011 and identified 26 patients with DAVF. We gathered information from the clinical case records, angiographic images, MRI on presentation and during follow-up. The findings were analyzed to aid discussion. Among 87 patients treated by multi-stage endovascular embolization, age range from newborn to 19 years, 26 (30%) had DAVF. In seven patients (8%), DAVF were found on initial angiogram and were all into the VOGM. Nineteen (21%) DAVF found on follow-up angiograms were all into the VOGM and distant locations. Sprouting and non-sprouting angiogenesis resulted in the formation of a network of vessels around partially thrombosed VOGM, recruiting blood from the surrounding dura mater resulting in a secondary network on the dura mater supplied by the blood vessels of dura mater in the region or from its natural collaterals. Embolization targeting DAVFs was done in 13 (52%) with complete cure in eight (32%) and recurrence in five (20%). Among 12 non-embolized patients (48%), eight (32%) had spontaneous regression with continued treatment of VOGM. In others, the DAVF either remained stable or progressed. DAVF associated with VOGM represent the dural response to angiogenic stimuli. They are observed to regress spontaneously or mature while continuing to treat the primary feeders of VOGM. It is important to include the external carotid system during angiograms. Persistent DAVF with residual VOGM that do not have access though the pial vessels are used as a conduit to treat the dural shunt and to achieve obliteration of residual VOGM at later stages of treatment.
