Bacteriological Profile and Antimicrobial Susceptibility Pattern of Cervico-Facial Cellulitis at the Regional Teaching Hospital of Ouahigouya (Burkina Faso)

Context and Objective: Cervicofacial cellulitis is a lethal infection without treatment. The aim of this study is to establish the bacteriological and antimicrobial susceptibility profile of cervico-facial cellulitis at the Regional Teaching Hospital (RTH) of Ouahigouya, in order to guide practitioners in the development of effective probabilistic antibiotic therapy protocols. Subjects and Methods: This was a transversal descriptive study with prospective data collection from July 1 to December 31, 2021 at the RTH of Ouahigouya. All cases of suppurative cervicofacial cellulitis that had been the subject of pyoculture were retained. Results: A total of 63 patients were chosen including 41 men, with 40.91 years as the average age and the sex ratio was 1.86. In 90.48% of cases, the front door was dental. All patients took antibiotics before their admission. Pus culture was positive in 34/63 subjects (53.97%) and showed monomicrobial infection. The isolates were Gram-negative bacilli for 20.59% and Gram-positive cocci for 79.41%. These isolates were all resistant to certain beta-lactams (such as amoxicillin, amoxicillin + clavulanic acid). However, some isolates were susceptible to cefoxitin, ceftazidime and ceftriaxone. All isolates were sensitive to amikacin for aminoglycosides. As for macrolides, erythromycin had excellent activity (100%) against Gram-positive cocci. Indeed, some isolates were susceptible and others resistant to ciprofloxacin for quinolones. Conclusion: Bacteriological profile and antimicrobial susceptibility knowledge of cervicofacial cellulitis may propose an effective probabilistic antibiotic therapy protocol.

Factors Associated with Prolonged Poor Glycemic Control in Type 2 Diabetes Mellitus (T2DM) Patients Followed in the Department of Internal Medicine at the Yalgado Ouedraogo Teaching Hospital, Ouagadougou (Burkina Faso)

Background: Achieving and maintaining glycemic targets are a challenge for health practitioners around the world. We aimed to study the factors associated with prolonged poor diabetes control in the cohort of T2DM patients monitored and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital in Ouagadougou in order to optimize therapeutic education in these patients. Methodology: This was a descriptive and analytical cross-sectional study combining retrospective data collection from the last year of patient follow-up and prospective collection of some information. The study included all diabetic patients, aged at least 18 years old, followed and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital between January 1, 2010 and December 31, 2018 following a systematic random sampling with a sampling step of 10. The variables collected were sociodemographic, anthropometric, lifestyle, cardiovascular risk factors and diabetes-related characteristics. To determine the risk factors associated with prolonged poor glycemic control, we performed modeling using logistic regression. All variables associated with prolonged poor glycemic control, in bivariate logistic regression with a p-value less than 0.20 were included in the full model. Later, we used a stepwise descending method to obtain the final model, which was then tested by a receiver operating characteristic (ROC) curve. The significance threshold was set at 5%. Raw and fitted Odds-Ratio (OR) and 95% confidence interval were presented. Results: 270 patients were included. Prolonged poor control of diabetes mellitus was observed in 73.70%. The mean age was 55.97 years (SD: ±11.52) and the sex ratio was 0.6 in favor of female. The mean time since diabetes mellitus diagnoses was 5.85 years (SD: ±5.15). A monthly gain of 92.62 USD (50.74%) for average diabetes mellitus care expenditures of 55.82 USD (SD: 28.25) was reported. An overweight (55.92%) and hypertension (41.85%) were reported. Diabetes mellitus was complicated in 68.15%. Patients were supported by their families in the management of their diabetes mellitus in 85.19%. In multivariate analysis with bivariate logistic regression, low level of formal education (OR = 8.34, 95% CI [1.97 - 35.22];p < 0.01), family support for diabetes mellitus management (OR = 0.65, 95% CI [0.45 - 0.94];p = 0.02), presence of abdominal obesity (OR = 2.27, 95% CI [1.08 - 4.77];p = 0.03), presence of a history of hospitalization (OR = 7.39, 95% CI [2.97 - 18.39];p < 0.01), poor adherence to antidiabetic treatment (OR = 2.97, 95% CI [1.42 - 6.18];p < 0.01), and the presence of microangiopathy (OR = 5.05, 95% CI [2.36 - 10.81];p < 0.01) were the factors independently associated with prolonged poor control of T2DM, with a ROC curve of 0.88, which reflects a very good sensitivity and specificity of these factors. Conclusion: The imbalance of T2DM is multifactorial. Lifestyle, family environment, and compliance seem to be essential to ensure good glycemic control. Healthcare practitioners should take these elements into account in their daily patient assessment. A predictive score would be a tool to help identify patients at risk of diabetes imbalance and would contribute to improving their management.

External Hemorrhoidal Thrombosis in Recent Births at the Maternity Ward of Saint Camille Hospital in Ouagadougou

Introduction: External hemorrhoidal thrombosis is a clinical is the most common postpartum proctologic accident. The aim of this work was to study hemorrhoidal thrombosis in recent mothers, in order to help improve its management. Patients and Methods: This was a descriptive and analytical cross-sectional study that was carried out at Saint Camille Hospital in Ouagadougou, Burkina Faso. Data collection was prospective and took place over a period of three months from September 1 to November 30, 2019. The study population consisted of recent births. The interview with the patients and their physical examination enabled the collection of data. Results: During the study period, 384 women were examined and 56 (14.6%) of whom presented with external hemorrhoidal thrombosis. The average age of patients who presented with external hemorrhoidal thrombosis was 29 years ± 5.2. The external hemorrhoidal thrombosis appeared in the form of a painful swelling at the level of the anal margin. In multivariate analysis, dyschezia and personal history of hemorrhoidal disease were risk factors for external hemorrhoidal thrombosis in the postpartum period (OR = 37.4 [6.8 - 205.7];OR = 23.9 [3.3 - 174.2]. Consumption of fruit and foods rich in dietary fiber were protective factors against the occurrence of this risk (OR = 0.02 [0.002 - 0.3]). Conclusion: External hemorrhoidal thrombosis remains a complication to be taken into account during the monitoring of postpartum women. It is important to encourage pregnant women to consume foods and fruits rich in fiber seem to reduce the risk of its occurrence.

Incidence and Predictors of Peripheral Venous Catheter-Related Complications in Hospitals in Burkina Faso

Introduction: Peripheral venous catheters (PVCs) are the most commonly used medical devices in hospitals for the administration of medications. Their use can lead to complications of varying severity. Objective: Determine the incidence and factors associated with the occurrence of PVC-related complications. Methods: This was a two-month prospective observational study conducted in the Medical Emergency Department (MED) of Yalgado Ouedraogo Teaching Hospital in Ouagadougou. All patients admitted during the study period who had a PVC inserted and removed were included in the study. Logistic regression analysis was used to identify the factors associated with the occurrence of complications. Results: In total, 459 PVCs were inserted and removed in 415 patients hospitalized at the Medical Emergency Department during the study period. The placement of 37.7% (n = 173) of PVCs resulted in complications in 131 patients (31.6%). For 644.3 days of catheterization, the incidence density was estimated at 6.5 complications per 1000 patient days. Phlebitis (24.0%), infection (5.7%), and accidental removal (2.8%) were the most frequently identified complications. The average age of the patients was 46.8 ± 18.9 years with a sex ratio of 1.22. The average patient hospitalization duration was 2.5 ± 2.6 days. In multivariate analysis, the factors significantly associated with the occurrence of complications after PVC insertion were patient’s state of agitation during the procedure (aOR = 12.59;95% CI = 4.12 - 38.49), placement of the PVC at the elbow bend (aOR = 2.17;95% CI = 1.86 - 5.52), multiple attempts (aOR = 3.18;95% CI = 1.49 - 6.75), administration of 10% hypertonic glucose solution (aOR = 3.67;95% CI = 1.62 - 8.33), and duration of catheterization beyond 72 hours without being changed (aOR = 33.00;95% CI = 14.19 - 76.75). Conclusion: The incidence of PVC-related complications was relatively high. The identification of the factors that can lead to these complications is relevant to the delivery of quality healthcare to patients.

Contribution of Simulation to the Skills Laboratory for the Learning of Obstetrical Examination in an African Setting with Limited Resources

Objective: To evaluate the interest of the simulation in the learning of the obstetric examination of parturient by medical students. Materials and methods: It was an analytical cross-sectional study that took place from 1 to 28 February 2020 at the Yalgado Ouedraogo Teaching Hospital in Ouagadougou, Burkina Faso. The study population was made up of medical students at the Doctorate II level. The previous experience of the students in the obstetric examination of the parturient, the contribution of the simulation on their feelings and on their skills towards this examination were studied. The Mc Nemar Chi2 test was used to compare percentages on paired samples. Results: The level of difficulty in performing the obstetrical examination in the parturient evolved downwards after the practice of the simulation. The stress level to perform the obstetric exam has been significantly reduced. On the other hand, confidence has increased. The students’ ability to appreciate each of the elements of the obstetric examination studied had improved after the practice of simulation. Conclusion: The simulation in the skills laboratory was a great contribution and the acquisition of models of better fidelity would help to improve the contribution to the confidence building and the acquisition of skills by learners.

Moyamoya Disease Associated with Hyperhomocysteinemia: A Rare Cause of Stroke in Sub-Saharan Africa

Introduction: Moyamoya disease (MMD) is a chronic cerebrovascular disorder characterized by progressive bilateral occlusion of the supraclinoid internal carotid artery (ICA) and its main branches, associated with the development of fine collateral networks, especially adjacent to the site of occlusion in the deep areas of the brain. MMD frequently occurs in East Asian populations, including pediatric and adult patients, and may lead to ischemic or hemorrhagic stroke, headache, epilepsy or transient ischemic attack. The majority is presumed to be of genetic origin and few cases of thrombophilia have been reported in MMD. We report a case of MMD in a young sub-Saharan African woman associated with Hyperhomocysteninemia (HHCys). Observation: A 33-year-old female was seen for aphasia, which had suddenly appeared fourteen days before, and was associated with memory impairment. She mentioned chronic headaches during the 10 previous years, of frontal seat, without migraine criteria. She had no history of hypertension, no obesity, no known dyslipidemia, and there was no family history of stroke. Neurological examination noted Wernicke’s aphasia, with discreet right central facial palsy, associated with memory impairment. The brain MRI revealed semi recent infarct in the left parietal lobe, sequelae in the left temporo-occipital and right frontal with lacunar ischemic lesions, associated with several foci of sub- cortical demyelination. MRA showed stenosis of the supraclinoid carotid arteries and their division branches. In addition, there was a stenosis of the posterior cerebral arteries, with a network of anastomosis at the level of the base of the skull. An investigation of thrombophilia showed hyperhomocysteinemia (HHCys). The diagnosis of moyamoya disease associated with hyperhomocysteinemia was mentioned. She was treated by Aspirin combined to folic acid. After a 3-year setback the patient was asymptomatic. Conclusion: MMD is a rare cause of stroke in sub-Saharan Africa. MRA should be performed whenever possible, as well as investigation for thrombophilia when it’s available. Combined antiplatelet agent with folic acid for ischemic stroke prevention is effective.

Lumbar Paraspinal Hemangiopericytoma, An Unusual Location: Surgery with Preoperative Embolization

Background: Lumbar paraspinal hemangiopericytoma is rare. The hemorrhagic nature of the tumor causes problems of hemostasis and makes the resection delicate. We report a rare case of lumbar paraspinal hemangiopericytoma managed with preoperative embolization. Clinical Case: It is about a woman of 31 years, admitted for a large left lumbar paraspinal mass that evolved for 6 years. The clinical exam showed an asymmetry of the left paraspinal muscle. The mass painless was extended from the lumbar region. The neurological exam was normal. MRI showed the left large paraspinal mass tissue. It was extended from lumbar vertebrae, L1 to L4, and measured 100 × 50 × 50 mm. It was an iso-intense signal on T1-weighted with strong enhancement after gadolinium. It was hypervascular and supplied by left intercostal T12, L1, and L2 pedicles. The complete exclusion of the hyper-vascular left paraspinal tumor was obtained after selective embolization of the artery left L1 of the pedicle of the intercostal left L1 and trunks intercostal T12 and L2 left. The total resection of a mass encapsulated was performed. The operative outcome was good. The histology concluded to a hemangiopericytoma. No chemotherapy or radiotherapy was prescribed. After 5 years, the patient was asymptomatic. MRI control confirmed tumor resection with a residue at the level of the left intervertebral foramen L1 - L2. Conclusion: Lumbar paraspinal hemangiopericytoma is an extremely rare tumor. Selective preoperative embolization is recommended before the resection of large tumors to reduce vascular supply. A follow-up extended for these patients is necessary, given the frequency of recurrences.
