Cervical precancerous lesions at the Tchibanga Regional Hospital and the University Hospital in Gabon in 2018: smartphone as a screening tool for diagnosis

Background

Cervical precancerous lesions are disorders that can induce discolouration changes. Their detection is difficult in remote areas in the absence of adequate equipment. The objectives were to evaluate Smartphone performance in diagnosing cervical precancerous lesions in Tchibanga, Gabon.

Methods

It was an interventional cross-sectional study to evaluate the validity and reliability of the smartphone as a tool for diagnosing atypical changes in the cervix. Study period was between July 1, 2017 to February 28, 2018 at the Tchibanga Regional Hospital (CHRT) and the University Hospital (CHU). The variability between examiners was determined according to Cohen's Kappa formula. The Gold standard test was the cytology.

Results

Compared to the examiner -1, the examiner - 2 found a high percentage of inflammations as atypical transformations : 15.3% versus 9%. With regard to smartphonic impressions, the examiner-1 found the normal impressions almost equal to that of the examiner-2, 72.9% versus 72.2%. The concordance between positive smartphonic impressions was 93.8% and 95.5% between negative smartphonic impressions, with k = 0.86.

Conclusion

In view of the above, the concordance between positive and negative smart phonic impressions was 93.8 and 95.5% with k = 0.86. The performance parameters being good, there is a need to use the smartphone as a tool for the diagnosis of precancerous lesions.

Explicative factors of occupational stress among caregivers in hospitals in Brazzaville: a cross-sectional analytical study

Introduction

staff health represent a population particularly exposed to numerous psycho-social risks. The organization, pace and workload, as well as difficulties in terms of working equipment or personnel have been shown to be a source and consequences of work stress. The objective is to study the factors of stress experienced by health professionals working in district hospitals and to propose preventive actions to decision-makers.

Methods

a cross-sectional analytical study carried out among caregivers in the hospitalization services of Brazzaville. The relationship between stress and certain characteristics of the participants was established using single and multiple logistic regressions taking into account potential confounding factors. For this purpose, Wald Chi-square tests were used as well as the odds ratio with their 95% confidence interval.

Results

midwives have a higher probability of experiencing stress OR = 2.12 [1.13- 4.20] caregivers with less than 10 years of practice are less likely to experience work-related stress OR = 0.53 [0.28 - 0.96] than those with more than 10 years of practice, p = 0.040. After adjusting for possible confounding factors, caregivers who felt useful at work experienced about 5 times more stress odds ratio adjusted (ORa) = 4.69 [1.82 - 12.78] p = 0.002 than those who did not feel useful.

Conclusion

the factors that influence stress among health workers are of a socio-professional nature, and related to the perception of working conditions. Some of them significantly increase the risk of experiencing work-related stress. Further studies are needed to better understand the consequences of occupational stress on the performance of caregivers.

Primary postpartum haemorrhage at the Libreville University Hospital Centre: Epidemiological profile of women

In Gabon, the proportion of maternal deaths directly related to Primary PostPartum Haemorrhage (PPPH) is 15 to 25%, despite the different means that the World Health Organization has made available to the providers of Emergency Obstetrical and Neonatal Care (EmONC). The objective of this study was to determine the prevalence and epidemiological characteristics of Primary PostPartum Haemorrhage to improve its management and reduce the rate of maternal deaths. An analytical retrospective study involved 42,728 records, whose data were collected using a chart collection form on the basis of information contained in partograms and other patient records. Sociodemographic variables were expressed using percentage. The relationship between the etiologies of PPPH and certain characteristics of the women was established using the ORs with their 95% confidence intervals. The difference was significant if p < 0.05. The prevalence of PPPH was 1.6%. Delivery haemorrhages accounted for 65.5% of PPPH. The main factors associated with delivery haemorrhages were pauci parity and multiparity (p = 0.003 and 0.051), post-term (p = 0.042), and birth weight >4,000 g (p = 0.006). Those associated with genital tract injuries were young maternal age (p = 0.008) and multiparity (p = 0.028). The most common etiology was haemorrhage from delivery. Multiparity remains the most common risk factor and the young age of the patients. It is important to improve management through better assessment of blood loss in the primary postpartum period as well as capacity building of health providers on EmONC.

Uterine cervical neoplasms mass screening at the University Hospital Centre of Libreville, Gabon: Associated factors with precancerous and cancerous lesions

The objectives of this study were to identify the associated factors with cancerous and precancerous lesions of cervix. In Africa, the incidence of uterine cervical neoplasms varies from one region to another, where most women with uterine cervical neoplasms are seen at an advanced stage. For this reason, uterine cervical neoplasms mass screening reduces the incidence and mortality due to this disease, similar to what is being done in Europe. A cross-sectional analytical study was conducted. Socio-demographic characteristics, gynaecological-obstetrical history, risk factors, data from visual inspection with acetic acid and visual inspection with Lugol, colposcopy impressions and results of cytological analysis were performed. A simple and multiple regression were performed to establish a statistically significant difference between certain factors and the presence of precancerous or cancerous lesions of uterine cervical. In this study, of 63 women diagnosed histologically, 43 had precancerous lesions and 20 had cancerous lesions. we found that being older than 35, having the first intercourse before 18, having an antecedent of STI, being a widow and using of tobacco were risk factors associated with precancerous lesions (p = 0.013 with OR = 3.44 (1.22–9.73), p = 0.009 with OR = 4.07 (1.69–13.08), p < 0.001 with OR = 3.80 (1.94–7.47), p < 0.001 with OR = 9.77 (3.87–24.70) and p < 0.001 with OR = 5.47 (2.60–11.52)) respectively. Only being older than 45, being a widow and using tobacco were risk factors associated with cancerous lesions (p = 0.021 with OR = 2.01 (1.58–3.56), p = 0.02 with OR = 2.96 (2.10–3.87), p = 0.041 with OR = 1.98 (1.46–2.44)) respectively. Among participants diagnosed with uterine cervical neoplasms, there was a significant association with the STI, marital status and smoking. Despite the integration of the detection of precancerous uterine cervical neoplasms lesions into health facilities in Gabon, uterine cervical neoplasms ranks second among women’s cancers in terms of incidence and first in terms of mortality.
