After assuming the Chinese presidency in March 2013, Xi Jinping introduced the new political slogan ＂the Chinese Dream,＂ which he does not only address to the domestic audience but also aims to promote to the world. Since his inaugural trip abroad, Xi has repeatedly speeches when addressing international catchphrase received as much appeal as used the term ＂Chinese Dream＂ in his audiences. However, nowhere has the in Africa. Simultaneously, African academics and other interested parties have observed the promotion of the idea of an African Dream by the Chinese Communist Party （CCP） with great suspicion as they view it simply as a projection of China＇s own foreign policy onto Africa. But what do the Chinese Dream and African Dream actually mean？ How can we make sense out of these terms？ In order to decode or demystify the meaning behind the Chinese Dream narrative in the context of China＇s foreign policy, this paper argues that it is essential to examine how it is constructed and projected to the international audience, in particular to Africa. The Chinese Dream is understood as a narrative which is strategically used by the CCP in order to shape perceptions and behavior of other international actors according to their own agenda. Moreover, the dynamic interactions between the media and politics and how they impinge on the formation and projection of the Chinese Dream and African Dream narrative will also be taken into account.

Background: Adolescent pregnancy is a serious health and social problem worldwide as well as in Cameroon. The aim of this study was to determine the obstetrical and perinatal outcomes of nulliparous adolescent pregnancies in a reference hospital in Cameroon. Methods: A retrospective cohort study to compare the outcomes of nulliparous adolescent pregnancies to those of nulliparous women aged 20 to 25 years was carried out at the Yaoundé General Hospital between January 1993 and December 2012. Results: Adolescent deliveries represented 2.84% (331 deliveries) of all deliveries registered during the study period. The adolescent mothers had a significantly higher incidence of preeclampsia/eclampsia, preterm delivery and low birth weight babies (<2500 g) when compared to the control group (OR, 3.46;CI 95%, 1.46 - 8.18;OR, 1.94 CI 95%, 1.34 - 2.79;OR, 1.98, CI 95%, 1.39 - 2.46, respectively). However, placenta previa, abruptio placenta, episiotomy, cesarean section, vaginal instrumental delivery, perineal tears and post partum hemorrhage were not significantly different in the two groups. Furthermore, there was no statistically significant difference between the two groups regarding fetal distress, low Apgar score (st and 5th minutes), the rate of admission in the neonatal intensive care unit, stillbirth and neonatal death. Conclusion: Adolescent pregnancy is associated with an increased risk of preeclampsia/ eclampsia, preterm birth and low birth weight.

Emphysematous gastritis (or phlegmonous gastritis) and gastric emphysema (or gastric pneumatosis) are variations of conditions associated with the presence of intramural air in the stomach. The presence of air in the gastric wall is a very rare clinical condition, associated with bacterial infection, increased intragastric pressure from gastric outlet obstruction, gastric mucosal disruption or air dissection from the mediastinum. In adults, this can occur in the setting of instrumentation-related injury, gastric outlet obstruction by gastric, duodenal or pancreatic malignancies or bowel ischemia. Here we describe a case of gastric emphysema related to repeated biliary stenting and partial duodenal obstruction in a patient with inoperable periampullary cancer, and provide the first description of the endoscopic ultrasonographic findings of gastric emphysema in the literature. In our case, endoscopic ultrasound showed a band of bright echogenicity arising from the submucosa layer, representing air in the gastric wall.

Background: Infertility is a global problem, but the highest prevalence is in low resource countries, particularly in sub-Saharan Africa where tubal damage following pelvic infection is the commonest cause. Objectives: This study aimed to assess contribution of laparoscopy as a diagnostic and therapeutic tool in infertile women in our setting. Methods: A descriptive review of complete medical records of 208 women who underwent laparoscopy at the Gynaecology Unit of Yaoundé General Hospital from December 2007 to December 2012. Results: Two hundred and eight women were enrolled in this study. Mean age was 32.6 ± 11.25 years. Infertility was secondary in 71.6% of cases;125 (60.1%) women were married and 116 (55.8%) had a positive serology of Chlamydia trachomatis infection. The most frequent findings during diagnostic laparoscopy were: pelvic adhesions (83.7%), hydrosalpinx (21.6%), pyosalpinx (4.8%), perihepatic adhesions (25.5%), uterine fibromas (22.6%), pelvic endometriosis (13%) and ovarian abnormalities (10.1%). The surgical procedures during laparoscopy were: adhesiolysis (79.7%), tuboplasty (35.0%), salpingectomy (8.2%), ovarian cystectomy (5.8%) and myomectomy (1.9%). Three (1.4%) cases of uterine perforation and 1 (0.5%) case of laparoscopy conversion to laparotomy were observed. Conclusion: Diagnostic laparoscopy revealed that tubal lesions and pelvic adhesions were still the major causes of female infertility in developing countries. Adhesiolysis and tuboplasty were the most frequently performed surgical procedures during laparoscopy. Therefore, training in endoscopic surgery should be regarded as an important issue in developing countries.

Background: Cervical cancer is the third most common cancer worldwide, and 80% of cases occur in the developing world. A critical component of effective cervical cancer screening programs is the ability to offer women appropriate and effective treatment for cervical intra epithelial neoplasia (CIN). Objectives: This study aimed at assessing the primary experience of management of CIN by Loop Electrosurgical Excision Procedure (LEEP) in a low resource country. Methods: We carried out a descriptive cross sectional study at the Yaoundé General Hospital in Cameroon. Results: Twenty three cases of CIN were treated by LEEP. Mean age of patients was 40.5 ± 9.9 years. Six (26.1%) patients were infected by the Human Immunodeficiency Virus (HIV). LEEP was indicated in 21 (91.30%) cases for CIN2 and CIN3. The mean duration of the surgical procedure was 10 ± 3 minutes. There was one (4.3%) complication (persistent cervical bleeding). Surgical margins were negative for dysplasia or invasive carcinoma in 18 (78.26%) cases and non-applicable in 5 (21.73%) cases (thermal artefacts of margins and cervicitis without CIN). One patient with micro invasive carcinoma on post-operative histology was treated by total hysterectomy. Cervical cytology was normal at 6 months post LEEP for 15 cases out of 16 (93.8%) patients who performed the test. One woman achieved pregnancy and delivered a term baby. Conclusion: Treatment of CIN by LEEP is feasible, safe and effective in our setting.

Objective: The aim of this study was to determine maternal and perinatal complications of pregnancies complicated by severe preeclampsia in three tertiary care centers in Cameroon. Methods: We carried out a descriptive cross sectional study from the 1st of June 2012 to the 31th of June 2014, among pregnant women with severe preeclampsia followed up in three tertiary level hospitals in Yaoundé, Cameroon: the Yaoundé General Hospital, the Yaoundé Central Hospital, and the Yaoundé University Hospital. Statistical analysis was performed using EPI 3.5.5. Data were described as means ± standard deviation, percentages and numbers. Chi-square and Fisher exact tests were used where appropriate. Results: Of the 2500 deliveries registered during the study period, 111 cases (8.49%) were managed as severe preeclampsia. Four patients refused to participate and were excluded from the study. Most of these patients were non workers (58.0%), pauciparous (61.7%) and young (median age of 27.47 years ± 6.46). Eclampsia (12.14%), abruptio placentae (11.21%) and hypertensive retinopathy (7.47%) were the most frequent maternal complications. Two cases (1.86%) of maternal deaths occurred in patients who had eclampsia. Prematurity (48.6%), intra uterine fetal death (13.1%) and oligoamnios (11.2%) were the most frequent fetal complications. All four neonatal deaths occurred in women in whom the diagnosis of severe preeclampsia was done between 28 and 33 weeks of gestation. Conclusion: Pregnancies complicated by severe preeclampsia had significantly high maternal and perinatal morbidity and mortality in Cameroon. The complications of severe preeclampsia can be prevented by more widespread use of antenatal care, education of primary medical care personnel, prompt diagnosis of high-risk patients and timely referral to tertiary medical centers.

This study aimed to estimate the survival rate of breast cancer in a group of patients followed up at the Yaoundé General Hospital in Cameroon. A retrospective review of records of patients managed for breast cancer between 1995 and 2007 was carried out at the Yaoundé General Hospital. Survival analysis was carried out with survival defined as the time between the date of unequivocal diagnosis of cancer and the date of last follow-up or death. Survival curves were plotted in R.3.1.1 software. Mean age of the patients was 47.5 ± 12.36 years. Most of the patients (67.9%) presented with advanced breast cancer disease (stage III and IV). Overall patient survival rate was 30% at 5 years and 13.2% at 10 years. Median overall survival time was 2 (1.9 - 3) years. There was a correlation between survival and the stage of disease. The highest survival rates were recorded in stages I and II while the lowest rates were recorded in stage IV. There was no statistically significant difference in survival among the age groups (p = 0.15). Overall survival rates of breast cancer are 30% at 5 years and 13.2% at 10 years among Cameroonian patients and are lower compared with 90% and 82% respectively at 5 years and 10 years in some developed countries.
