Presurgical embolization of nasopharyngeal fibroma: A case report.

Nasopharyngeal fibroma (NF) is a rare nasopharyngeal tumor of a benign histological nature but with local aggressiveness. It is a hypervascular tumor and the main feeding artery comes from the internal maxillary artery. Surgery is the treatment of choice for this tumor but carries a significant risk of bleeding from surgical treatment. Thus, embolization carried out preoperatively effectively reduces intraoperative bleeding and thereby allows complete resection for large tumors.

Interest of preoperative embolization of aneurysmal bone cyst (ABC): A case report.

Aneurysmal bone cyst (ABC) is a rare lesion that primarily affects young adults and children. The optimal treatment approach for ABC remains controversial and varies depending on the preferences of the medical team. While some advocate for surgery as the treatment of choice, others recommend a less invasive first-line option such as selective embolization. In this case report, we present the case of a 41-year-old female patient with an ABC in the right iliac bone who underwent surgical treatment following preoperative selective embolization. Additionally, we provide a literature review on the topic.

Improvement of the In Vitro Cytotoxic Effect on HT-29 Colon Cancer Cells by Combining 5-Fluorouacil and Fluphenazine with Green, Red or Brown Propolis.

Cancer is regard as one of the key factors of mortality and morbidity in the world. Treatment is mainly based on chemotherapeutic drugs that, when used in targeted therapies, have serious side effects. 5-fluorouracil (5-FU) is a drug commonly used against colorectal cancer (CRC), despite its side effects. Combination of this compound with natural products is a promising source in cancer treatment research. In recent years, propolis has become the subject of intense pharmacological and chemical studies linked to its diverse biological properties. With a complex composition rich in phenolic compounds, propolis is described as showing positive or synergistic interactions with several chemotherapeutic drugs. The present work evaluated the in vitro cytotoxic activity of the most representative propolis types, such as green, red and brown propolis, in combination with chemotherapeutic or CNS drugs on HT-29 colon cancer cell lines. The phenolic composition of the propolis samples was evaluated by LC-DAD-ESI/MSn analysis. According to the type of propolis, the composition varied; green propolis was rich in terpenic phenolic acids and red propolis in polyprenylated benzophenones and isoflavonoids, while brown propolis was composed mainly of flavonoids and phenylpropanoids. Generally, for all propolis types, the results demonstrated that combing propolis with 5-FU and fluphenazine successfully enhances the in vitro cytotoxic activity. For green propolis, the combination demonstrated an enhancement of the in vitro cytotoxic effect compared to green propolis alone, at all concentrations, while for brown propolis, the combination in the concentration of 100 µg/mL gave a lower number of viable cells, even when compared with 5-FU or fluphenazine alone. The same was observed for the red propolis combination, but with a higher reduction in cell viability. The combination index, calculated based on the Chou-Talalay method, suggested that the combination of 5-FU and propolis extracts had a synergic growth inhibitory effect in HT-29 cells, while with fluphenazine, only green and red propolis, at a concentration of 100 µg/mL, presented synergism.

Social Immersion for Women After Repair for Obstetric Fistula: An Experience in Guinea.

Background: Reintegration of women after repair of their female genital fistula remains a challenge. The objective of this study was to document the medical pathway and the reintegration process of women through the "social immersion" program of EngenderHealth in Kissidougou and Labé (Guinea). Methods: This was a qualitative descriptive study with 55 participants, including women seeking fistula care and stakeholders involved in the social immersion for repaired women in Kissidougou and Labé. The study included collecting demographic and clinical data of women, interviews with women before and after surgery, after social immersion, and 3 months post-discharge. Municipal officials, health providers, and members of host families were also interviewed. The study protocol was approved by the Guinea National Ethics Committee for Health Research. Results: The study confirmed that obstetric fistula still occurs among women living in rural and underserved areas. Most women attended at least two to five antenatal care visits, but nine over 10 reported a tragic experience of child loss associated with the occurrence of fistula. Most of them received support from their husband/partner during referral after the obstructed labor and later in the search for treatment. Women and stakeholders reported a good experience of surgery and social immersion in both Kissidougou and Labé. About 3 months after discharge, women who were continent reported being happy with their new life compared to women discharged with repair failure and residual incontinence. Conclusion: The study found the positive impacts of social immersion on the quality of life of women after fistula repair, particularly for those women who had a successful repair. The approach can be included in fistula care programs, either through direct provision or through referral to programs that can provide this service.

Ultrasonography of peritoneal tuberculosis.

Purpose: The objective of this work was to describe different presentations of peritoneal tuberculosis on ultrasound. Materials and methods: This was a retrospective study conducted between 2008 and 2016 at the Main Hospital in Dakar, and including 38 cases of peritoneal tuberculosis. The tests were performed on Philips Envisor and Hitachi Preirus with 10 and 12 MHz linear transducers. The mean age was 26 years and the sex ratio was 0.8. The diagnosis of peritoneal tuberculosis was based on histological evidence (17 cases), isolation of BK from sputum (5 cases), positive adenosine deaminase in ascites fluid (4 cases) or a favorable clinical course after trial antituberculosis treatment (4 cases). The structures studied were the parietal peritoneum, the mesentery, the large omentum, as well as the characteristics of ascites, and extra-peritoneal lesions. Results: Parietal peritoneal involvement was found in 89.4% of patients, including regular diffuse hypoechoic thickening in 70.5% and nodular thickening in 11.7%. Ascites was present in 84.2% of patients. The great omentum showed anomalies in 73.6% of cases in relation to 3 aspects: trilamellar thickening made up of a thick, hyperechoic central layer surrounded by 2 thin peripheral hypoechoic layers in 46.4% of cases; a single-layer hyperechoic thickening in 21.4% of cases; heterogeneous hyperechogenic thickening with hypoechoic nodules in 32.1% of cases. Mesentery abnormalities were noted in 63.1% of patients with hypoechoic thickening. Conclusion: Ultrasound with the advantage of safety and accessibility is a reliable technique for the diagnosis of peritoneal tuberculosis. In some cases, it allows for a guided percutaneous biopsy to avoid the use of laparoscopy.Purpose: The objective of this work was to describe different presentations of peritoneal tuberculosis on ultrasound.

Fistula recurrence, pregnancy, and childbirth following successful closure of female genital fistula in Guinea: a longitudinal study.

BACKGROUND: Female genital fistula is a devastating maternal complication of delivery in developing countries. We sought to analyse the incidence and proportion of fistula recurrence, residual urinary incontinence, and pregnancy after successful fistula closure in Guinea, and describe the delivery-associated maternal and child health outcomes. METHODS: We did a longitudinal study in women discharged with a closed fistula from three repair hospitals supported by EngenderHealth in Guinea. We recruited women retrospectively (via medical record review) and prospectively at hospital discharge. We used Kaplan-Meier methods to analyse the cumulative incidence, incidence proportion, and incidence ratio of fistula recurrence, associated outcomes, and pregnancy after successful fistula closure. The primary outcome was recurrence of fistula following discharge from repair hospital in all eligible women who consented to inclusion and could provide follow-up data. FINDINGS: 481 women eligible for analysis were identified retrospectively (from Jan 1, 2012, to Dec 31, 2014; 348 women) or prospectively (Jan 1 to June 20, 2015; 133 women), and followed up until June 30, 2016. Median follow-up was 28·0 months (IQR 14·6-36·6). 73 recurrent fistulas occurred, corresponding to a cumulative incidence of 71 per 1000 person-years (95% CI 56·5-89·3) and an incidence proportion of 18·4% (14·8-22·8). In 447 women who were continent at hospital discharge, we recorded 24 cases of post-repair residual urinary incontinence, equivalent to a cumulative incidence of 23·1 per 1000 person-years (14·0-36·2), and corresponding to 10·3% (5·2-19·6). In 305 women at risk of pregnancy, the cumulative incidence of pregnancy was 106·0 per 1000 person-years, corresponding to 28·4% (22·8-35·0) of these women. Of 50 women who had delivered by the time of follow-up, only nine delivered by elective caesarean section. There were 12 stillbirths, seven delivery-related fistula recurrences, and one maternal death. INTERPRETATION: Recurrence of female genital fistula and adverse pregnancy-related maternal and child health outcomes were frequent in women after fistula repair in Guinea. Interventions are needed to safeguard the health of women after fistula repair.

Factors associated with the failure of obstetric fistula repair in Guinea: implications for practice.

BACKGROUND: The prevention and treatment of obstetric fistula still remains a concern and a challenge in low income countries. The objective of this study was to estimate the overall proportions of failure of fistula closure and incontinence among women undergoing repair for obstetric fistula in Guinea and identify its associated factors. METHODS: This was a retrospective cohort study using data extracted from medical records of fistula repairs between 1 January 2012 and 30 September 2013. The outcome was the failure of fistula closure and incontinence at hospital discharge evaluated by a dye test. A sub-sample of women with vesicovaginal fistula was used to identify the factors associated with these outcomes. RESULTS: Overall, 109 women out of 754 (14.5 %; 95 % CI:11.9-17.0) unsuccessful repaired fistula at discharge and 132 (17.5 %; 95 % CI:14.8-20.2) were not continent. Failure of fistula closure was associated with vaginal delivery (AOR: 1.9; 95 % CI: 1.0-3.6), partially (AOR: 2.0; 95 % CI: 1.1-5.6) or totally damaged urethra (AOR: 5.9; 95 % CI: 2.9-12.3) and surgical repair at Jean Paul II Hospital (AOR: 2.5; 95 % CI: 1.2-4.9). Women who had a partially damaged urethra (AOR: 2.5; 95 % CI: 1.5-4.4) or a totally damaged urethra (AOR: 6.3; 95 % CI: 3.0-13.0) were more likely to experience post-repair urinary incontinence than women who had their urethra intact. CONCLUSION: At programmatic level in Guinea, caution should be paid to the repair of women who present with a damaged urethra and those who delivered vaginally as they carry greater risks of experiencing a failure of fistula closure and incontinence.

Factors associated with loss to follow-up in women undergoing repair for obstetric fistula in Guinea.

OBJECTIVES: To analyse the trend of loss to follow-up over time and identify factors associated with women being lost to follow-up after discharge in three fistula repair hospitals in Guinea. METHODS: This retrospective cohort study used data extracted from medical records of fistula repairs conducted from 1 January 2007 to 30 September 2013. A woman was considered lost to follow-up if she did not return within 4 months post-discharge. Factors associated with loss to follow-up were identified using a subsample of the data covering the period 2010-2013. RESULTS: Over the study period, the proportion of loss to follow-up was 21.5% (448/2080) and varied across repair hospitals and over time with an increase from 2% in 2009 to 52% in 2013. After adjusting for other variables in a multivariate logistic regression model, women who underwent surgery at Labe hospital and at Kissidougou hospital were more likely to be lost to follow-up than women operated at Jean Paul II hospital (OR: 50.6; 95% CI: 24.9-102.8) and (OR: 11.5; 95% CI: 6.1-22.0), respectively. Women with their fistula closed at hospital discharge (OR: 3.2; 95% CI: 2.1-4.8) and women admitted for repair in years 2011-2013 showed higher loss to follow-up as compared to 2010. Finally, loss to follow-up increased by 2‰ for each additional kilometre of distance a client lived from the repair hospital (OR: 1.002; 95% CI: 1.001-1.003). CONCLUSION: Reimbursement of transport was the likely reason for change over time of LTFU. Reducing geographical barriers to care for women with fistula could sustain fistula care positive outcomes.

Good clinical outcomes from a 7-year holistic programme of fistula repair in Guinea.

OBJECTIVES: Female genital fistula remains a public health concern in developing countries. From January 2007 to September 2013, the Fistula Care project, managed by EngenderHealth in partnership with the Ministry of Health and supported by USAID, integrated fistula repair services in the maternity wards of general hospitals in Guinea. The objective of this article was to present and discuss the clinical outcomes of 7 years of work involving 2116 women repaired in three hospitals across the country. METHODS: This was a retrospective cohort study using data abstracted from medical records for fistula repairs conducted from 2007 to 2013. The study data were reviewed during the period April to August 2014. RESULTS: The majority of the 2116 women who underwent surgical repair had vesicovaginal fistula (n = 2045, 97%) and 3% had rectovaginal fistula or a combination of both. Overall 1748 (83%) had a closed fistula and were continent of urine immediately after surgery. At discharge, 1795 women (85%) had a closed fistula and 1680 (79%) were dry, meaning they no longer leaked urine and/or faeces. One hundred and fifteen (5%) remained with residual incontinence despite fistula closure. Follow-up at 3 months was completed by 1663 (79%) women of whom 1405 (84.5%) had their fistula closed and 80% were continent. Twenty-one per cent were lost to follow-up. CONCLUSION: Routine programmatic repair for obstetric fistula in low resources settings can yield good outcomes. However, more efforts are needed to address loss to follow-up, sustain the results and prevent the occurrence and/or recurrence of fistula.

The value of building health promotion capacities within communities: evidence from a maternal health intervention in Guinea.

This article presents results from a study that explored the association between community capacity for maternal health promotion and women's use of preventive and curative maternal health services. Implemented in the Republic of Guinea, the intervention aimed to build the capacity of community-level committees to heighten awareness about maternal health risks and to promote use of professional maternal health services throughout pregnancy and childbirth. Data were collected through a population-based survey. A total of 2335 women of reproductive age were interviewed, including 878 with a live birth or stillbirth since the launch of the intervention. An index of community capacity was created to explore the effect of living in a community with strong community-level resources and support for maternal health. Other composite variables were created to measure the content of women's antenatal counselling and their individual exposure to maternal health promotion activities at the community level. Multivariate logistic regression was used to explore the effect of community capacity and individual exposure variables on women's use of antenatal care (ANC) (≥4 visits), institutional delivery, and care for complications. Our results show that women living in communities with a high score on the Community Capacity Index were more than twice as likely as women in communities with low score to attend at least four ANC visits, to deliver in a health facility, and to seek care for perceived complications. Building the capacity of community-level cadres to promote maternity care-seeking by women in their villages is an important complement to facility-level interventions to increase the availability, quality and utilization of essential health services.
