Lithiase géante sur enterocystoplastie

La formation des lithiases est une complication fréquente des entérocystoplasties après cystectomie radicale pour tumeur de vessie infiltrante. Le délai d'apparition dépend des facteurs de risque favorisants notamment les infections urinaires. Néanmoins la survenue de lithiase géante sur néovessie reste exceptionnelle, seulement 5 cas ont été rapportés dans la littérature. Nous rapportons dans ce travail, le cas d'une lithiase géante compliquant une entérocystoplastie chez un malade suivi pour tumeur de vessie infiltrante

Chloroquineand hydroxychloroquine in covid 19: asystematic review

Since 100 years, current coronavirus pandemic (COVID-19) caused by SARS-CoV-2 is themostdangerous healthcare crisis and unprecedented in absense of prophylactic or therapeutic drugs. The world's major health systems have had no large-scale therapeutic choice and at an acceptable cost apart from Chloroquine (CQ) and its derivative hydroxychloroquine (HCQ) to treat Covid-19.These drugs have anti-inflammatory activity and are already used to treat rheumatoid arthritis, lupus. However, these drugs have raised a great worldwide controversy between the pros and cons of their uses to treat patientswith Covid-19In these systematic review, we analyzed articles published until 28 august in pubmed, sciences direct and ClinicalTrials.gov by using these keywords: chloroquine and COVID-19 or hydroxychloroquine and COVID-19. these online preprint publications have offered inconclusive preliminary results as well as clinical trials not yet finished. Although CQ / HCQ have antiviral activity against Sars cov 2 in vitro, antiviral activity in vivo is questionable

Place de la laparoscopie dans la prise en charge des anomalies de différenciation sexuelle: à propos de 4 cas

Les troubles de la différenciation sexuelle sont à l'origine d'une discordance entre le sexe proprement dit (phénotypique) et le sexe génétique (génotypique) ce qui pose un problème de détermination du sexe. Dans les pays de faible niveau socio-économique où le diagnostic anténatal est souvent absent et les plateaux techniques insuffisants, la prise en charge médico-chirurgicale est difficile. Le but de ce travail est de préciser la place de la laparoscopie dans la prise en charge de l'ambiguïté sexuelle à travers l'observation de 4 cas et une revue de la littérature.Pan African Medical Journal 2016; 2

[81] Correlation between intravesical prostatic protrusion and the failure of medical treatment

Objective: To study the correlation between the index of intravesical protrusion of the prostate (IPP) and the failure of medical treatment in the treatment of urinary disorders for patients with prostatic adenoma. Methods: This is a retrospective study lasting 2 years from 01/01/2016 to 01/01/2018, performed in the Urology Department of the International University Hospital Cheikh Khalifa in Casablanca. In all, 156 patients were included, having had ⩾3 months of medical treatment. Patients were divided into two groups according to the extent of IPP: Group 1 included 67 patients with an IPP of 10 mm. The International Prostate Symptom Score and post-void residual urine volume (PVR) were compared between the groups at the beginning and 3 months after medical treatment. Results: Comparison of results between the two groups show a greater improvement in scores for Group 1 compared to Group 2. Such a finding has been reported by previous studies with a greater improvement in the absence of a median lobe. Conclusion: Determining the IPP index seems to be essential before any treatment. Medical treatment may be less effective in improving symptom scores and PVRs in patients with an IPP of >10 mm

[83] Lateral suspension of cystocoele prolapse by laparoscopic robotic surgery: A series of 27 patients

Objective: To evaluate the efficacy of lateral suspension of cystocoele prolapse by laparoscopic robotic surgery using a vaginal mesh. Genital prolapse is frequent and can be found in ∼50% of parous women. Its aetiology is complex and multifactorial. Developments in surgical techniques and synthetic material in the last 20 years have enabled us to use minimally invasive procedures with improved postoperative course and decreased recurrence rates. Methods: We report on 27 cases of women with cystocoeles. The treatment was a laparoscopic robotic surgery using a vaginal mesh with lateral suspension. From January 2016 to March 2017, 27 women with genital prolapse were included in a continuous series. The treatment was a laparoscopic robotic surgery using a vaginal mesh with lateral suspension. Data concerning patient characteristics (age, parity, menopause, body mass index, surgical history) were identified, as well as functional symptoms. Postoperative anatomical and functional status was evaluated by each operator on a regular basis. Results: The mean operative time was 102 min and the mean postoperative stay was 1.8 days. In the 27 procedures, there was a case of subtotal hysterectomy and in three cases urinary incontinence treatment. Bladder injury was noted in one patient. No case of conversion to laparotomy was encountered. Conclusion: Our experience in managing genital prolapse by robotic laparoscopy with the placement of lateral suspension prosthesis gives satisfactory results. We report a low rate of complications, and anatomical and functional results comparable to other techniques

[40] Day surgery prostate resection by bipolar photovaporisation using the transurethral resection in saline (TURis) system: First experience in Africa

Objective: To prospectively evaluate the efficacy, safety and postoperative complications of prostate resection for benign prostate hypertrophy (BPH) by bipolar photovaporisation using the transurethral resection in saline (TURis) system (BPV) in a day surgery setting. Methods: Over a 21-month period, 520 patients who fulfilled the selection criteria were recruited to have day surgery prostate resection using BPV. Preoperative International Prostate Symptoms Score (IPSS) and urine flow data were obtained in every patient. Perioperatively, we measured prostate resection time, weight of resected tissue and occurrence of any complications. Bladder residual content and duration of transurethral drainage were measured postoperatively. Results: The mean (range) prostate tissue weight was 51 (45–80) g. The mean (range) operative duration was 45 (35–70) min. No conversions and no major complications occurred in any cases. The transurethral catheter was removed in 110 cases before discharge and in 410 cases the following day. All cases left hospital the same day. All patients had noticeable improvement in IPSS and maximum urinary flow rate. Conclusion: BPV of BPH in selected patients can be carried out safely as a day care procedure and has beneficial outcomes for patients and services

[82] Efficacy of bipolar photovaporisation of prostate median lobe enlargement using the transurethral resection in saline (TURis) system

Objective: To evaluate the efficiency of a vaporisation-resection of prostate median lobe enlargement in benign prostatic hyperplasia (BPH) using the transurethral resection in saline (TURis) system. Bipolar photovaporisation of the prostate has proven to be effective in the treatment of BPH symptoms with maximum safety and without increasing the complication rate or length of stay. Methods: TURis has proven over last few years its efficacy as an endoscopic technique in BPH and has shown greater advantages in patient safety and outcomes postoperatively. Results: TURis has recently been widely practised because it is less expensive, simple to learn, thus allowing practitioners a rapid learning curve. It has also been used in high-risk patients. Conclusion: Technically, bipolar resection of prostate using the TURis system is entirely suitable for treatment of median lobes

Towards an optimization of the formulation of geopolymers in the fresh state: Rheological approach

In this work, we are interested in describing the evolution of the rheological behavior of geopolymer materials since their elaboration until the start of their kinetics of setting. We considered the case where these materials are obtained from the dissolution of a quantity S of metakaolin in a quantity L of alkaline activation solution (sodium-based). In this context and for all the values of the structural identification parameters P = (% Na2O) and R3 = (L/S) in our experiments, it has been established that the rheological behavior is described by the viscoplastic Herschel-Bulkley model. In particular, we have been able to determine how rheological parameters of the model are affected by variations of P and / or R3. For the considered formulations, this analysis is of importance insofar as it was at the base of the identification of critical values of P and R3. Moreover, we verified that for these values, the setting time is maximum. This result is retained to define the optimized formulation of our materials

Influence of the Integration of Geopolymer Wastes on the Characteristics of Binding Matrices Subjected to the Action of Temperature and Acid Environments

Recycling geopolymer waste, by reusing it as a raw material for manufacturing new geopolymer binding matrices, is an interesting asset that can add to the many technical, technological and environmental advantages of this family of materials in the construction field. This can promote them as promising alternatives to traditional materials, such as Portland cements, which are not so environmentally friendly. Recent studies have shown that the partial replacement of reactive aluminosilicates (metakaolin and fly ash) up to a mass rate of 50% by geopolymer waste does not significantly affect the compressive strength of the new product. In line with these findings, this paper investigates the effects of aggressive environments, i.e., high temperatures (up to 1000 °C) and acid attacks (pH = 2), on the characteristics of these new matrices. Different techniques were used to understand these evolutions: mineralogical analysis by X-ray diffraction (XRD), thermogravimetry-differential thermal analysis (TGA-DTA), mechanical characterization and scanning electron Microscopy (SEM) observations. The results are very satisfactory: in the exposure temperature range explored, the new matrices containing geopolymer waste suffered losses in compressive strength similar to those of the matrices without waste (considered as materials reference). On the other hand, the new matrices exhibited good chemical stability in acid media. These results confirm that the reuse of geopolymer waste is a promising recycling solution in the construction sector

Preparation of Cement Clinker from Geopolymer-Based Wastes

In order to avoid potential environmental pollution from geopolymer-based material wastes, this work investigated the feasibility of using these materials as alternative raw materials in the preparation of cement clinker. The geopolymer binders and mortars were used as substitutes for natural mineral clays since they are rich in silica and alumina. Simulated geopolymer wastes were prepared by the activation of metakaolin or fly ash by an alkaline silicate solution. The cement-clinkers fired at 1450 °C for 1h were characterized by XRD, XRF, SEM-EDS, and a free lime (CaOf) content test. The anhydrous clinker mineral phases C3S (Ca3SiO5), C2S (Ca2SiO4), C3A (Ca3Al2O6), and C4AF (Ca4Al2Fe2O10) were well-crystallized in all investigated formulations. The free lime was lower than 1.3 wt% in all elaborated clinkers, which indicates a high degree of clinkerization. The results demonstrate that geopolymer binder and mortar materials are suitable substitutes for natural mineral clay incement clinker preparation
