Maternal and Foetal Outcomes Associated with Caesarean Deliveries in Patients with Severe Preeclampsia in Two Teaching Hospitals, Yaoundé

Introduction: Severe preeclampsia is a frequent cause of maternal death, and also a frequent indication for caesarean deliveries when faced with the need to expedite delivery. We sought complications specific to caesarean deliveries in patients with severe preeclampsia. Methods: It was a case-control study carried out over 6 months, from December 1st, 2015 to May 31st, 2016 at the Yaoundé Central and the Yaoundé Gynaeco-Obstetric and Paediatric Hospitals. We evaluated 159 women undergoing a caesarean delivery to assess the risk of maternal and foetal postoperative complications in patients with severe preeclampsia. Significance level was set at 0.05. Results: The incidence of postoperative complications stood at 26.4%. Maternal and foetal complications were more frequent in preeclamptic women at 54.5% versus 11.5% (p < 0.05) and 47.3% versus 27.9% (p < 0.05) respectively. The incidence of adverse events was greater in women with preeclampsia: pruritus and limb pain (RR = 2.96;p < 0.001), the persistence of high blood pressure (RR = 4.51, p < 0.001), maternal death (RR = 2.93, p < 0.001), postpartum convulsions (RR = 3, p < 0.001) headaches resistant to first-line analgesics (RR = 3, p < 0.001), Disseminated Intravascular Coagulation (DIC) (RR = 2.92, p < 0.001), a cute pulmonary oedema (RR = 2.92, p < 0.001), prematurity (RR = 4.43, p < 0.001), neonatal asphyxia (RR = 2.93, p < 0.001), and hyaline membrane disease (RR = 2.93, p Conclusion: Severe preeclampsia is associated with an increased risk of postoperative complications.

Relevance of Chest CT Scan Requests in Two University Teaching Hospitals in a Developing Country

Chest investigation is common in hospital practice. Chest X-ray is readily available and usually the first chest investigation. Thoracic CT scan constitutes an alternative and complimentary chest investigation. It is currently the most efficient investigation for the chest and its contents. Objectives: To evaluate the relevance of chest CT Scan requests in two university teaching hospitals in Cameroon. Material and Methods: We conducted a cross-sectional, retrospective and descriptive study at the Radiology and imaging units of the Yaounde Central Hospital and the Yaounde University Teaching Hospital Centre. Included in our study were files of patients who had a chest CT scan investigation during three years. Results: We had a study population of 323 subjects. The age interval was 23 months to 91 years old. Pulmonologist were the most prescribers with 27.2%. We had 80% conformity of indications with French Society of Radiology (FSR) standards. 50 over of 323 indications were not recommended by the FSR. Conclusion: There is a conformity rate of 80% between indications and the FSR recommendations.

Relevance and Compliance of Requests for Dental Panoramic Radiography Examination at Yaounde (Cameroon)

Background: Research studies made in Cameroon on compliance and relevance in the various areas of imaging, show the failure to comply with administrative and clinical criteria. These research studies led to recommendations meant for result amelioration. However, the orthopantomogram (OPT) field remains less studied in that regard in Cameroon. Aim: Evaluate the relevance and compliance of examination requests for panoramic dental radiography. Setting and Design: It is a descriptive cross-sectional study with a consecutive sample of dental panoramic requests identified during the study period in 4 radiology centres of Yaoundé. Material and Methods: Variables studied here were the validity criteria of imaging examination. Request: Five of which are of administrative order (date of the request, requesting department, patient’s identity, patient’s age, applicant’s identity) and three of clinical order (anatomic region, reason for the examination and the purpose of the examination). Statistical Analysis: Chi-squared test was used with confidence interval of 95%. Results: Patient’s identity (name) was the criteria carrying the highest information (98.9%), followed by the name of the applicant physician (91.6%). Out of 179 requests analysed, 8.6% had complete information. 46.4% of requests had no indications. Dental surgeon was the top prescriber with a total of 112 (62.6%). Conclusion: The quality of dental panoramic requests was not optimal in Yaounde, with lack of precision mostly noted at the level of clinical criteria.
