Coronavirus disease 2019 (COVID-19) affects the respiratory system. Studying the clinical characteristics of this infection has revealed its tropism to the nervous system, which is responsible for neurological and sensory damage, in particular, dizziness and hearing loss. To determine the frequency and characteristics of the neurological impairment represented by dizziness and hearing loss in healthcare professionals (HCP) with COVID-19. Cross-sectional descriptive study conducted among HCP at Charles Nicolle Hospital (CNH) in Tunis affected by COVID-19 during the period from September 2020 to December 2020. Data collection was carried out by regular telephone follow-up of COVID-19 symptoms in these HCPs during the period of sanitary isolation. A total of 482 HCPs with COVID-19 were collected. The average age of the population was 41 ± 10 years, of which 111 were men (23%) and 371 were women (77%). The main neurological manifestations were: headache (71.2%), anosmia (60%), dizziness (21.8%), and hearing loss (1.5%). Patients with vertigo were significantly older (P=0.035), female (P=0.003), obese (P=0.014), suffering from more comorbidities (P=0.004), and having greater professional seniority (P=0.009). Dizziness was significantly associated with fever (P=0.001), abdominal pain (P=0.001), and desaturation (P=0.039). Neurological symptoms including dizziness and hearing loss may be the only sign with which a case of COVID-19 could be recognized. Raising awareness of such a presentation of COVID-19 patients is crucial during this pandemic period to prevent infectious spread, especially in hospitals.

Introduction: burst abdomen is a preventable complication of caesarean section that carries an increased risk of maternal death, especially in developing countries including Tanzania. The study aimed to identify the risk factors and high-risk patients for burst abdomen at Muhimbili National Hospital in Tanzania.

Methods: a case-control study was performed at Muhimbili National Hospital in Dar es Salaam from 2^nd April to 27^th December 2019. Characteristics of interest of one case of burst abdomen were compared to three randomly selected controls that consisted of caesarean deliveries either 24 hours before or after the time of delivery of cases. The chi-square test, Fischer´s exact test, and multivariate analysis were used. The level of significance was p < 0.05.

Results: a total of 524 women that met the inclusion criteria, comprising 131 cases and 393 controls, delivered by caesarean section in the most recent pregnancy at Muhimbili National Hospital. Cases were independently associated with perioperative illness, including cough (OR 3.8, 95%CI 1.9-7.6), chorioamnionitis (OR 4.5, 95% CI 1.3-14.7), and surgical site infection (OR 3.2, 95% CI 1.7-6.4), and a vertical midline incision wound (OR 1.9, 95% CI 1.2-3.1) compared to control group. Most cases (70%) had intact sutures and loose surgical knots.

Conclusion: burst abdomen remains a cause of unnecessary severe maternal morbidity and is independently associated with perioperative illnesses such as cough, chorioamnionitis surgical site infection, and a vertical midline abdominal incision. Thus, there is a need for modifying abdominal fascia closure techniques for patients at risk.

This study assessed the safety of Antiarrhythmic Drug (AAD) administration in a patient experiencing sinus bradycardia following radiofrequency ablation for Atrial Fibrillation (AF), followed by cardiac ganglion ablation. Post-AF radiofrequency ablation, the employment of AADs is a prevalent clinical practice; however, these drugs may exacerbate bradycardia, leading to increased patient discomfort and treatment complexity. The decision to employ AADs in patients with sinus bradycardia post-AF ablation poses a significant clinical challenge. This investigation aimed to ascertain the safety of AADs in such patients. The study encompassed a single case, wherein a patient with pre- and post-procedure sinus bradycardia was treated with AADs following AF radiofrequency ablation and cardiac ganglion ablation, with a subsequent safety assessment. The findings indicate that AADs can be safely administered to patients with sinus bradycardia after these procedures, offering valuable insights for clinical decision-making. This case report underscores the intricacies of post-AF ablation management in patients with sinus bradycardia and advocates for personalized therapeutic strategies. The results enhance the clinical knowledge regarding the safety of AADs in this patient subset and may guide future treatment protocols. Nonetheless, the study's conclusions are drawn from a single case, and further research with larger cohorts is essential to substantiate these findings and elucidate the long-term safety and efficacy of this therapeutic approach.

Introduction: infertility is a significant public health concern in Africa and Hysterosalpingography (HSG) is an affordable option for initial treatment. This study aimed to provide information about the incidence of abnormal pathology and tubal findings in HSG of Sudanese women who experienced infertility.

Methods: this prospective cross-sectional study included 100 infertile patients who were requested for HSG, including age, duration of infertility, body mass index (BMI), medical history, and HSG findings collected after performing the radiographic test, which was diagnosed by an experienced radiologist.

Results: one hundred infertile women (46% and 54%) experienced primary and secondary infertility, respectively. Mean age was (31.1 ± 5.2, 27.5 ± 6.0) years, and BMI was (25.1 ± 3.3, 25.7 ± 2.9) Kg/cm² for primary and secondary infertility respectively. Abnormal findings prevalence was (29/46, 63%) and (30/54, 56%). The incidence of fallopian tube abnormality was (52/100, 52% (25/46, 54.3%), and (27/56, 50%) for primary and secondary infertility, respectively. Forty-one percent of participants had normal hysterosalpingograms. Pelvic surgery was the highest risk factor in 24% of the participants. Age and medical history were significantly associated with the infertility type (P < 0.05).

Conclusion: infertile patients who underwent hysterosalpingography (HSG) were predominantly older, with secondary infertility being slightly more common, underscoring the importance of early diagnostic evaluation and care. Fallopian tube abnormalities were the most common cause of infertility, with tube blockage affecting nearly half of the participants. Additionally, this study revealed that prior pelvic surgery significantly increased the risk of infertility.

Introduction: vaccination is one of the strategies the World Health Organization recommends to reduce the burden of COVID-19. However, many African countries like Cameroon have low COVID-19 vaccination coverage. The purpose of this study was to investigate the reasons for the refusal of the population of the city of Douala to be vaccinated against COVID-19.

Methods: we conducted a cross-sectional and analytical study in Douala from February 10 to May 31, 2022. Participants, aged at least 21 years and residing in the city of Douala, were interviewed. Associations between the variables of interest were measured using Chi-square and Fisher tests, with a 95% confidence interval.

Results: a total of 1555 people were included in the study. Only 168 (11%) had been vaccinated. The proportion of vaccine refusal was high, with 711 (45.7%) refusing, 640 participants (41.1%) hesitating, and 204 people (13.2%) being in favor of COVID-19 vaccination. The main reasons for refusing anti-COVID-19 vaccination were fear of adverse effects (406; 44.8%), lack of information about vaccines (331; 36.5%), and lack of confidence (302; 33.3%). Factors associated with vaccine refusal were religion (p=0.026) and level of education (p=0.002).

Conclusion: this study revealed low COVID-19 vaccination coverage in Douala, with a significant proportion of refusal and hesitation towards vaccination. Communication strategies should take into account the reasons and factors associated with refusal.
