RESUMEN
Methylenetetrahydrofolate reductase (MTHFR) plays a major role in the metabolism of folates and homocysteine, which in turn can affect gene expression and ultimately promote the development of breast cancer. Thus, mutations in the MTHFR gene could influence homocysteine, methionine, and S-adenosylmethionine levels and, indirectly, nucleotide levels. Imbalance in methionine and S-adenosylmethionine synthesis affects protein synthesis and methylation. These changes, which affect gene expression, may ultimately promote the development of breast cancer. We therefore hypothesized that such mutations could also play an important role in the occurrence and pathogenesis of breast cancer in a Malian population. In this study, we used the PCR-RFLP technique to identify the different genotypic profiles of the C677T MTHFR polymorphism in 127 breast cancer women and 160 healthy controls. The genotypic distribution of the C677T polymorphism in breast cancer cases was 88.2% for CC, 11.0% for CT, and 0.8% for TT. Healthy controls showed a similar distribution with 90.6% for CC, 8.8% for CT, and 0.6% for TT. We found no statistical association between the C677T polymorphism and breast cancer risk for the codominant models CT and TT (p > 0.05). The same trend was observed when the analysis was extended to other genetic models, including dominant (p = 0.50), recessive (p = 0.87), and additive (p = 0.50) models. The C677T polymorphism of MTHFR gene did not influence the risk of breast cancer in the Malian samples.

OBJECTIVE: The aim of this study is to compare robotic total mesorectal excision (R-TME) with laparoscopic TME (L-TME) in a series of consecutive rectal cancer patients. BACKGROUND: R-TME and L-TME have drawn contradictory reports. A recent phase III trial (ROLARR) concluded that R-TME performed by surgeons with varying experience did not confer an advantage in rectal cancer resection. PATIENTS AND METHODS: In this retrospective single-center cohort study (8/2008 to 4/2015), data were prospectively registered. A total of 200 L-TME and 200 R-TME were operated consecutively without selection. The primary outcome was the conversion rate to open laparotomy or transanal TME. The secondary endpoints were type of anastomosis, operative time, postoperative morbidity, circumferential radial (CRM) and distal margins, quality of life, bladder and sexual dysfunction, and oncological outcomes. RESULTS: Baseline characteristics were well balanced. Type of anastomosis [colo-anal anastomosis (CAA) 40% vs 49%; p < 0.001], transanal TME (5% vs 13%; p = 0.005), and conversion rate (2% vs 9.5%; odd ratio (OR): 0.19 [95% confidence interval (CI): 0.05-0.60]) were significantly different. Intersphincteric resection (39% vs 47%), diverting stoma (66.5% vs 68%), CRM involvement, median operative time (243 vs 232 min), and R0 resection rate were similar. Conversion risk was lower for R-TME in male patients and those with small tumors (< 5 cm). The 3-year overall survival rate was 84.1% [77.3-88.9%] and 88.4% [82.9-92.2%] in the R-TME and L-TME group. No significant differences were reported in quality of life, and urinary or sexual function. CONCLUSIONS: R-TME is less likely to be converted to open surgery than L-TME; operative time and curative pathologic criteria are equivalent. Future prospective trial should compare standardized procedures performed by experienced surgeons for subgroups of high-risk patients.

BACKGROUND: Oncoplastic surgery for breast cancer (BC) may result in postoperative morbidity that can delay adjuvant treatment(s). The McKissock procedure is a reliable mammaplasty technique used in plastic surgery. The authors present their experiences in using a derived technique for the oncoplastic resection of extended malignancies located in the lower-inner (LIQ) or lower-outer (LOQ) breast quadrants. METHODS: Between 2011 and 2014, operative data of 25 patients receiving an oncoplastic resection for invasive BC or ductal carcinoma in situ (DCIS), using the modified McKissock procedure, were recorded. This technique conserved a bipedicle dermoglandular flap to improve the nipple-areola complex blood supply. Oncological and cosmetic results, as well as aesthetic outcomes and patients' satisfaction, were analyzed. RESULTS: Invasive BCs (n = 21) and DCIS (n = 4) were located in the LIQ (n = 18) or LOQ (n = 7). The median age of patients was 62 years (range 34-85), the mean resection weight was 134 g (range 43-314), and the global morbidity rate was 12 %. No nipple necrosis occurred in these patients. Free margins were obtained in 22 cases (88 %) and the secondary mastectomy rate was 8 %. Contralateral symmetrization was performed, or was required, in the majority of cases (17/23). Cosmetic results were classified as excellent or good in 93 % of patients, and the median satisfaction rate on a visual analog scale was 9.6. CONCLUSION: The modified McKissock procedure allows wide resection of cancers located in the LOQ or LIQ, and produced favorable postoperative outcomes and cosmetic results despite important resection weights.

Breast cancer is the second most common cancer, with more than 2.31 million cases diagnosed worldwide in 2022. Cancer medicine subjects the body to invasive procedures in the hope of offering a chance of recovery. In the course of treatment, the body is pricked, burned, incised and amputated, sometimes shattering identity and often changing the way women perceive the world. In sub-Saharan Africa, incidence rates are steadily increasing and women are particularly young when they develop breast cancer. Despite this alarming situation, the scientific literature on breast cancer in sub-Saharan Africa is poor and largely dominated by medical literature. Using a qualitative approach and a theoretical framework at the intersection of the sociology of gender and the sociology of the body, we explore the discourse strategies of women with breast cancer in Mali regarding their relationship to the body and to others. Based on 25 semi-directive interviews, we analyse the experiences of these women. Using the image of the Amazon woman, whose struggle has challenged gender because of its masculine attributes, we explore whether these women's fight against their breast cancer could be an opportunity to renegotiate gender relations. The experience of these women is characterised by the deconstruction of their bodies, pain and suffering. The masculinisation of their bodies and their inability to perform certain typically female functions in society (such as cooking or sexuality) challenges their female identity. The resistance observed through the sorority, discreet mobilisation and display of their bodies does not seem to be part of a renegotiation of gender relations, but it does play an active role in women's acceptance of the disease and their reconstruction.

BACKGROUND AND PURPOSE: The indication and benefit of plasma level of antiepileptic (AEDs) has been debating in the monitoring of people living with epilepsy and the epilepsy treatment gap has largely been documented in developed countries. This study was aimed to highlight the epilepsy treatment gap between rural and urban Mali. METHODS: We conducted a pilot study on AEDs treatment from September 2016 to May 2019. For 6 months, 120 children and young adults living with epilepsy (rural site, 90; urban site, 30) received phenobarbital, valproic acid and/or carbamazepine. At our rural study site, we determined the AED plasma levels, monitored the frequency, severity and the duration of seizure, and administered monthly the McGill quality of life questionnaire. At our urban study site, each patient underwent an electroencephalogram and brain computed tomography scan without close monitoring. RESULTS: At the rural study site, patients were mostly on monotherapy; AED levels at 1 month (M1) (n=90) and at 3 months (M3) (n=27) after inclusion were normal in 50% at M1 versus 55.6% at M3, low in 42.2% at M1 versus 33.3% at M3 and high in 7.8% at M1 versus 11.1% at M3. AED levels at M1 and at M3 were significantly different p<0.0001. By M3, seizures (n=90) were <1/month in 26.7%, and lasted less than 1 minute in 16.7%. After a yearlong follow up, all 90 patients reported a good or excellent quality of life. At our urban study site, patients (n=30) were on carbamazepine and valproid acid in 66.67% and monotherapy (carbamazepine) in 33.33%. By November 2018, only six out 30 patients (on bi-therapy) were still taking their medications. CONCLUSIONS: Epilepsy diagnostic and treatment are a real concern in Mali. Our data showed appropriate AED treatment with close follow up resulted in a better quality of life of patients in rural Mali. We will promote the approach of personalized medicine in AED treatment in Mali.
RESUMEN
BACKGROUND: In 1986, the Government of Mali launched its Expanded Program on Immunization (EPI) with the goal of vaccinating, within five years, 80% of all children under the age of five against six target diseases: diphtheria, tetanus, pertussis, poliomyelitis, tuberculosis, and measles. The Demographic and Health Survey carried out in 2001 revealed that, in Kita Circle, in the Kayes region, only 13% of children aged 12 to 23 months had received all the EPI vaccinations. A priority program was implemented in 2003 by the Regional Health Department in Kayes to improve EPI immunization coverage in this area. METHODS: A cross-sectional survey using Henderson's method (following the method used by the Demographic and Health Surveys) was carried out in July 2006 to determine the level of vaccination coverage among children aged 12 to 23 months in Kita Circle, after implementation of the priority program. Both vaccination cards and mothers' declarations (in cases where the mother cannot make the declaration, it is made by the person responsible for the child) were used to determine coverage. RESULTS: According to the vaccination cards, 59.9% [CI 95% (54.7-64.8)] of the children were fully vaccinated, while according to the mothers' declarations the rate was 74.1% [CI 95% (69.3-78.4)]. The drop-out rate between DTCP1 and DTCP3 was 5.5%, according to the vaccination cards. The rate of immunization coverage was higher among children whose mothers had received the anti-tetanus vaccine [OR = 2.1, CI 95% (1.44-3.28)]. However, our study found no difference associated with parents' knowledge about EPI diseases, distance from the health centre, or socio-economic status. Lack of information was one reason given for children not being vaccinated against the six EPI diseases. CONCLUSION: Three years after the implementation of the priority program (which included decentralization, the active search for missing children, and deployment of health personnel, material and financial resources), our evaluation of the vaccination coverage rates shows that there is improvement in the EPI immunization coverage rate in Kita Circle. The design of our study did not, however, enable us to determine the extent to which different aspects of the program contributed to this increase in coverage. Efforts should nevertheless be continued, in order to reach the goal of 80% immunization coverage. ABSTRACT IN FRENCH: See the full article online for a translation of this abstract in French.
RESUMEN
Rectal cancer continues to be a surgical challenge. As more technology is developed, the surgeon must both incorporate this new technology into his practice and, at the same time, keep improving oncologic surgery and overall outcomes. We describe a standardized approach and fully robotic proctectomy, using four arms and one single docking (SI system). Patient cart and ports placement, as well as arms position to avoid collision, are key points to perform the entire procedure with one single docking. Although the place of robotic surgery might still need to be defined, standardizing the procedures is a step towards its evaluation. We propose with this report a solution to perform a single docking four arms robotic proctectomy.

GOAL: The aim of this study was to take stock of the practice of the loco-regional anesthesia (LRA) at the University Hospital Center of Point G from January 2004 to December 2008. MATERIALS AND METHOD: This is a retrospective study, assessing the practice of LRA. The demographic data, the surgery, the technical characteristics of the procedure made, the type of local anesthetic used, adverse events were evaluated. RESULTS: The LRA involved 1261 patients - 8.30% of the total number of surgical procedures occurring during the studied period. The American Society of Anesthesiology (ASA) classification was used for the evaluation of patients in scheduled surgery. The patients belonged to class 1 (50.40%) and Class 2 (49.60%). The main surgical procedures were: 26.20% surgical prostatic adenomectomy, 23.80% of caesarean section, and the fistulogram test for 19.04%. The LRA techniques performed were: spinal anesthesia, 87.60%, epidural anesthesia, 12%. Three hundred and three adverse events (24%) have been reported, three (1%) of them have resulted in the death of the patient. The incidence of arterial hypotension was 94.40%, and 4.6% for bradycardia. The three heart attacks were fatal (0.024 ). Patients operated under spinal anesthesia and patients aged 60 years and older had more adverse events with 20% and 10.38% for p <0.05 respectively. Sixty eight failures (5.4%) were observed. CONCLUSION: The practice of LRA at the University Hospital of Point G is characterized by adverse events and a low number of deaths. Patients operated under spinal anesthesia and patients aged 60 years and older are at greatest risk of adverse events.
OBJECTIF: Etait de faire le point de la pratique de l'ALR au Centre Hospitalier Universitaire (CHU) du Point G, de janvier 2004 à décembre 2008. MATERIELS ET METHODE: Il s'agissait d'une étude retrospective, évaluant la pratique de l'ALR. Les données démographiques, l'acte chirurgical, les caractéristiques techniques du geste effectué, le type d'anesthésique local utilisé, les événements indésirables ont été évalués. RESULTATS: L'ALR avait concerné 1.261 patients, soit 8,30%. La classification de l'American Society of Anesthesiology (ASA) était utilisée pour l'évaluation des patients en chirurgie programmé. Les patients étaient de la classe ASA1 (50,40%) et de la classe ASA2 (49,60%). Les principaux actes chirurgicaux étaient: l'adénomectomie 26,20%, la césarienne 23,80% et la fistulorraphie 19,04%. Les techniques d'ALR réalisées étaient: la rachianesthésie, 87,60%, l'anesthésie péridurale, 12%. Trois cents trois événements indésirables soit 24% ont été rapportés, dont trois soit 1% ont entrainé le décès du patient. L'incidence de l'hypotension artérielle a été de 94,40%, la bradycardie de 4,6%. Les trois arrêts cardiaques ont été fatals (0,024). Les patients opérés sous rachianesthésie et les patients âgés de 60 ans et plus avaient présenté plus d'événements indésirables avec respectivement 20% et 10,38% pour un p < 0,05. Soixante huit échecs (soit 5,4%) avaient été constatés. CONCLUSION: La pratique de l'ALR au CHU du Point G est caractérisée par des événements indésirables et un nombre de décès faible. Les patients opérés sous rachianesthésie et les patients âgés de 60 ans et plus sont les plus exposés aux événements indésirables.
