Vaginal birth after laparoscopic management of heterotopic pregnancy at the Douala general hospital, Cameroon: A case report

Heterotopic pregnancy is the simultaneous presence of an intrauterine and ectopic pregnancy. The prevalence of the condition is unknown in Cameroon. We report a case of heterotopic pregnancy managed by laparoscopy. MS a 33‑year‑old G2P0010 woman was admitted to our department because of 7 2/7 weeks’ amenorrhea, mild vaginal bleeding, and severe lower abdominal pain. She has a 6 years’ history of secondary infertility, one induced abortion, and chlamydia infection treated with doxycycline. Furthermore, she has a history of left laparoscopic salpingotomy for tubo‑ovarian abscess. She became pregnant after receiving clomiphene citrate and timed intercourse. Her beta hCG assay was 97000 mIU/mL and transvaginal sonography confirmed ruptured heterotopic pregnancy. She underwent laparoscopic left salpingectomy and the intrauterine pregnancy evolved normally and she gave birth to a healthy female that weighed 3050 g at 38 5/7 weeks gestation. The diagnosis of heterotopic pregnancy needs a high index of suspicion. Laparoscopic treatment of heterotopic pregnancy needs to become widespread in Cameroon. Key words: Heterotopic pregnancy; laparoscopic salpingectomy; transvaginal sonography; vaginal birth

Cervical cancer in the Bamenda Regional Hospital, North West Region of Cameroon: a retrospective study

Introduction: cervical cancer is ranked the 7th most common cancer in the world. Cancer of the cervix is the second most commonly diagnosed cancer after breast cancer and the third leading cause of cancer deaths among females in less developed countries. Incidence rates are highest in countries with low income. Nearly 90% of cervical cancer deaths occur in developing parts of the world. The study researchers therefore, carried out a retrospective study to determine the proportion of cervical cancer among other types of cancer in the cancer registry of the Bamenda Regional Hospital. Methods: the objective of this study was to determine the proportion of cervical cancer among other types of cancers in the cancer registry of the Bamenda Regional Hospital, North West Region of Cameroon from past records. We reviewed all records from the registry of patients who attended the Bamenda Regional Hospital to screen and/or be operated upon for cervical cancer and other types of cancer. Socio-demographic and clinical characteristics of cases were captured using a data collection sheet: age, type of cancer, stage of cancer, type of surgery carried out and date of surgery. Data were entered and analysed in Statistical Package for Social Sciences (SPSS) version 25 software. Results: 59 cancer cases were received in the center between 2012 and 2017. Of these, 31 (52%) had cervical cancer. Most patients who screened positive for cancer of the cervix were of the 50-54 age groups. Most of these patients (47.5%), were received at late stages (stages 3 and 4). Conclusion: over half (52%) of the patients receiving cancer care in this center have cervical cancer and generally turn up late for management

Study protocol for a two-site clinical trial to validate a smartphone-based artificial intelligence classifier identifying cervical precancer and cancer in HPV-positive women in Cameroon.

INTRODUCTION: Cervical cancer remains a major public health challenge in low- and middle-income countries (LMICs) due to financial and logistical issues. WHO recommendation for cervical cancer screening in LMICs includes HPV testing as primary screening followed by visual inspection with acetic acid (VIA) and treatment. However, VIA is a subjective procedure dependent on the healthcare provider's experience. Its accuracy can be improved by computer-aided detection techniques. Our aim is to assess the performance of a smartphone-based Automated VIA Classifier (AVC) relying on Artificial Intelligence to discriminate precancerous and cancerous lesions from normal cervical tissue. METHODS: The AVC study will be nested in an ongoing cervical cancer screening program called "3T-study" (for Test, Triage and Treat), including HPV self-sampling followed by VIA triage and treatment if needed. After application of acetic acid on the cervix, precancerous and cancerous cells whiten more rapidly than non-cancerous ones and their whiteness persists stronger overtime. The AVC relies on this key feature to determine whether the cervix is suspect for precancer or cancer. In order to train and validate the AVC, 6000 women aged 30 to 49 years meeting the inclusion criteria will be recruited on a voluntary basis, with an estimated 100 CIN2+, calculated using a confidence level of 95% and an estimated sensitivity of 90% +/-7% precision on either side. Diagnostic test performance of AVC test and two current standard tests (VIA and cytology) used routinely for triage will be evaluated and compared. Histopathological examination will serve as reference standard. Participants' and providers' acceptability of the technology will also be assessed. The study protocol was registered under ClinicalTrials.gov (number NCT04859530). EXPECTED RESULTS: The study will determine whether AVC test can be an effective method for cervical cancer screening in LMICs

Surgery for non-Hodgkin’s lymphoma

Non-Hodgkin lymphomas (NHLs) are a diverse group of blood cancers derived from lymphocytes that vary significantly in their severity. Surgery is not often used as a treatment because of the efficacy of chemotherapy, biological therapy, radiotherapy and hematopoietic stem cell transplantation. We reviewed the natural history and possible role of surgery for NHL. Surgery may be useful in confirming or refuting an equivocal radiological diagnosis through biopsy, removing symptomatic limited disease from an affected organ and in splenectomy for primary splenic lymphoma. Emergency abdominal surgery for acute complications of NHL provides palliation and diagnosis. There is as yet no consensus as to the optimum treatment for symptomatic limited disease affecting an organ and timing of chemotherapy perioperatively. Prospective randomized trials are required

Research Paper - HEALING EFFECT ON CHRONIC GASTRIC ULCERS AND SHORT-TERM TOXICITY PROFILE OF THE LEAF METHANOL EXTRACT OF OCIMUM SUAVE WILD (LAMIACEAE) IN RATS

The gastric cytoprotective actions of the extract of Ocimum suave wild (lamiaceae) have previously been demonstrated. We have investigated here the healing effect of the leaf methanol extract of Ocimum suave against chronic gastric ulcers induced in experimental rats. Chronic gastric ulcers were induced using acetic acid and the induced ulcers treated over a period of two weeks using daily oral doses (125 - 500 mg/kg) of the extract. Possible toxic effects of the extract given in the short term were also investigated. The extract reduced ulcer indices from 50.40 in the 4-day controls to 11.8, 5.8, and 3.6, respectively, for the rats receiving 125, 250 and 500 mg/kg of the extract. The highest dose of the extract (500 mg/kg) showed a highly significant (P < 0.001) reduction of ulceration with a corresponding healing rate of 81.25 per cent. Treatment with the plant extract was also associated with a significant increase in mucus production up to 57 per cent (P < 0.01) for the 500 mg/kg dose. A similar increase in mucus production was not observed with ranitidine although it generated a healing rate of 66 per cent. No apparent toxicity signs were observed through food and fluid intakes, vital organ weights, animal behaviour, stool texture, red and white blood cell counts and histopathological evaluation. The results of the present study show that in addition to the previously demonstrated cytoprotective antiulcer actions of the leaf methanol extract of O. suave, the extract also possesses potent healing effects against chronic gastric ulcers. Enhanced mucus production appears to play a significant role in the mode of action of the extrac

Evaluation of the anti-ulcer and toxicity profile of Aloe buettneri in laboratory animals

The anti-ulcerogenic potential of the leaf methanol extract of Aloe buettneri A. Berger was investigated using three methods of gastric lesion induction in experimental Wistar rats (150-200 g) and mice (20-25 g): 1. HCl/ethanol-induced gastic lesions, 2. Indomethacin-HCl/ethanol-induced gastric lesions, and 3, Pylorus ligation-induced gastric lesions. Mice were used in acute and sub acute toxicity tests. Oral administration of the extract of Aloe buettneri to the rats and mice (500-1000 mg/kg) dose-dependently prevented the formation of acute gastric lesions induced using the three experimental techniques. The dose-dependent reduction of lesion formation was accompanied by a significant increase in gastric mucus production in mice. Inhibition of lesion formation was 22 and 54 % in mice, 25 and 77% in rats for the doses of 500 and 1000 mg/kg when the HCl/ethanol mixture was given. Pre-treatment, by oral route, with indomethacin significantly reduced the ability of the extract to inhibit the formation of HCl/ethanol-induced lesions, inhibition dropping to 11% for the dose of 1000 mg/kg. When the rats were subjected to pylorus ligation, the level of lesion inhibition was 36 and 68% for the two doses of extract. Gastric acid secretion reduced to 88 and 79mEq/l compared with105 mEq/l for the controls. Acute toxicity studies did not reveal toxic effects up to the dose of 10 g/kg. However, sub acute studies revealed toxicity effects in heart (pericarditis), lung (diffuse alveolar disease) and liver (chronic active hepatitis) tissue. These results confirm the ethnomedical use of Aloe buettneri in the management of gastroduodenal ulcer disease and suggest that toxic effects may result from prolonged intake of high doses of the extract.
