Background: Infertility is the inability to sustain a pregnancy in a woman with regular (2-3 times per week) unprotected sexual intercourse for a period of 1 year. This is a major public health problem that remains underrecognised in Cameroon and most countries in sub-Saharan Africa. This study aimed at identifying the risk factors associated with tubal infertility in a tertiary hospital in Douala, Cameroon. Methods: We conducted a case-control study at the Obstetrics, Gynaecology and Radiology Departments of the Douala Referral Hospital from October 1, 2016, to July 30, 2017. We recruited 77 women with tubal infertility diagnosed using hysterosalpingography and 154 unmatched pregnant women served as controls. Data on socio-demographic, reproductive and sexual health, and radiologic assessments were collected using a pretested questionnaire. The data were analysed using the Statistical Package for the Social Sciences (SPSS) software version 24.0. Logistic regression models were fitted to identify demographic, reproductive health factors, surgical, medical and toxicological factors associated with tubal infertility. The adjusted odds ratios (AOR) and their 95% confidence interval were interpreted. Statistical significance set at p < 0.05. Results: Sixty-one per cent of respondents had secondary infertility. Following multivariate logistic regression analysis, respondents who were housewives (AOR 10.7; 95% CI: 1.68-8.41, p = 0.012), self-employed (AOR 17.1; 95% CI: 2.52-115.8, p = 0.004), with a history of Chlamydia trachomatis infection (AOR 17.1; 95% CI: 3.4-85.5, p = 0.001), with Mycoplasma infection (AOR 5.1; 95% CI: 1.19-22.02, p = 0.03), with ovarian cyst (AOR 20.5; 95% CI: 2.5-168.7, p = 0.005), with uterine fibroid (AOR 62.4; 95% CI: 4.8-803.2, p = 0.002), have undergone pelvic surgery (AOR 2.3; 95% CI: 1.0-5.5, p = 0.05), have undergone other surgeries (AOR 49.8; 95% CI: 6.2-400, p = 0.000), diabetic patients (AOR 10.5; 95% CI 1.0-113.4, p = 0.05) and those with chronic pelvic pain (AOR 7.3; 95% CI: 3.2-17.1, p = 0.000) were significantly associated with tubal infertility while the young aged from 15 to 25 (AOR 0.07; 95% CI: 0.01-0.67, 0.021), those in monogamous marriages (AOR 0.05; 95% CI: 0.003-1.02, p = 0.05), as well as those with a history of barrier contraceptive methods (condom) (AOR 0.17; 95% CI: 0.03-1.1, p = 0.06) were less likely to have tubal infertility.

BackgroundLumbar spinal stenosis (LSS) refers to narrowing of the lumbar central spinal canal, lateral recess, and/or neuro-foramina. Radiographic LSS plays an important role in clinical LSS but is not solely accountable for the presence of symptoms. We sought to characterise clinical LSS and to determine factors associated with presence of symptoms of LSS in patients with radiographic LSS in a sub Saharan Africa setting.MethodsAfter prior ethical clearance, a case control study was done in a tertiary hospital in Douala-Cameroon, including 105 patients with radiographic LSS: 57 with symptoms of LSS (cases) and 58 with no symptoms (controls). Spinal stenosis was assessed using computed tomography (CT) scans. Data were analysed using SPSS version 23.ResultsThe mean age of our study participants was 53.4 ± 13.1 years. The mean age of onset of symptoms of LSS was 50.3 ± 11.6 years and the most common symptoms were Low back pain (100.0%), radicular symptoms (98.2%) and neurogenic claudication (98.2%). Obesity (p < 0.001) and a high waist circumference (p = 0.002) were significantly associated with presence of LSS symptoms in persons with radiographic LSS. After adjusting for body mass index, a positive family history of low back pain (p = 0.004), vertebra lesion at L2 (p = 0.034), L3 (p = 0.002), L4 (p = 0.025) and multiple (p = 0.008) levels, degenerative disc protrusion (p = 0.044), disc lesion at L3-L4 (p = 0.001), L4-L5 (p = 0.011) and multiple (p = 0.046) levels were significantly associated with presence of symptoms of LSS in persons with radiographic LSS.ConclusionCharacteristics of clinical LSS have been described in this sub-Saharan Africa population. Obesity, a high waist circumference and a positive family history of low back pain are significantly associated with presence of symptoms of LSS in persons with radiographic LSS.

Background: Hysterosalpingography (HSG) is the first-line investigation among infertile women in Cameroon. There is a dearth of studies on the use of HSG in Cameroon. The aim of this study was threefold: 1) to describe the indications; 2) findings of hysterosalpingography and 3) factors associated with abnormal findings on HSG at the Douala General Hospital, Cameroon. Methods: We conducted a retrospective descriptive study of 242 files of patients who underwent hysterosalpingography at the Radiology Department of the Douala General Hospital from January 2012 to December 2016. We collected data on the sociodemographic, obstetric variables and indications of HSG using a pretested data collection form. We also interpreted HSG films during the study period. Data analysis was with EPI-INFO version 7. Results: The age range was 19-46 years with a mean age of 33.16 ± 5.45 years. Majority 138/242 (57.1%) were in the age group 30-40 years. The main indication of HSG was infertility 87.2% (211/242). Most of the cases 95.87% (232/242) had abnormal findings at HSG. Tubal and uterine abnormal findings made up 133/232 (57.3%), and 97/232 (41.81%) of cases, respectively. Tubal occlusion and hydrosalpinges were found in 99/232 (42.67%) and 19/232 (8.19%) while uterine fibroids and uterine synechiae were found in 57/232 (24.97%) and 30/232 (12.93%), respectively. The factors independently associated with abnormal findings at HSG were: a history of recurrent pregnancy loss (AOR 2.95; 95% CI: 1.19-7.32, p = 0.02) and infertility (AOR 0.24; 95%
