Abstract
Inflammatory pseudo-tumors of the bladder are rare benign tumors that mostly arise in the differential diagnosis of sarcomas in children. The authors report an unusual case of pedunculated inflammatory pseudo-tumor of the bladder that externalized by the urethral meatus in a 13-year-old girl. The treatment consisted of a ligation-resection of the pedicle, followed by resection of the tumor. After regular follow-up for 18 months there was no tumor recurrence.

CHEMOSPHERE 2015; 136:1-8. [PMID: 25880813 DOI: 10.1016/j.chemosphere.2015.03.047] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Revised: 02/25/2015] [Accepted: 03/21/2015] [Indexed: 06/04/2023]
Abstract
The degradation of 2.5L of Allura Red AC solutions in sulfate medium containing 0.50mM Fe(2+) has been studied by solar photoelectro-Fenton (SPEF) using a flow plant equipped with a Pt/air-diffusion cell and a solar photoreactor. Comparative electro-Fenton treatment yielded rapid total decolorization but poor mineralization, since most products were slowly destroyed by OH formed from Fenton's reaction between Fe(2+) and H2O2 generated at the air-diffusion cathode. In contrast, the potent action of UV radiation from sunlight in SPEF allowed the rapid photolysis of recalcitrant intermediates, thus giving rise to a quick mineralization. Sulfate and nitrate ions, along with a large proportion of volatile N-derivatives, were always released. The increase in current density and decrease in azo dye concentration accelerated the decolorization and mineralization in SPEF, although lower current efficiency and greater specific energy consumption were obtained. The most cost-effective SPEF treatment was found for 460 mg L(-1) azo dye in 0.05 M Na2SO4 at 50 mA cm(-2), which yielded 95% mineralization with 81% current efficiency and 8.50 kW h m(-3). No significant effect of sulfate concentration was found. Up to 16 aromatic intermediates and 11 short-chain carboxylic acids, including oxalic and oxamic as the most persistent ones, were detected by GC-MS and HPLC. The large oxidation ability of SPEF can be explained by the quick photolysis of Fe(III)-oxalate complexes and other undetected intermediates.

Abstract
The degradation of 130 mL of mixtures of food azo dyes E122, E124 and E129 has been studied by electro-Fenton (EF) and UVA photoelectro-Fenton (PEF) using a stirred tank reactor with either a boron-doped diamond (BDD) or Pt anode and an air-diffusion cathode. The main oxidant was hydroxyl radical formed at the anode from water oxidation and in the bulk from Fenton's reaction between added Fe(2+) and H2O2 generated at the cathode. In sulfate medium, fast decolorization was found for all systems, but the almost total mineralization was more rapidly achieved by PEF with BDD. The performance with a real water matrix was slightly worse, although the removal of total organic load was still as high as 95%. The solar PEF (i.e., SPEF) treatment of dye mixtures using a 2.5 L flow plant with a BDD/air-diffusion cell coupled to a planar solar photoreactor is also reported. Fast decolorization and almost total mineralization was found in the presence of either sulfate, perchlorate, nitrate or a mixture of sulfate + chloride ions. In chloride medium, however, the formation of recalcitrant chloroderivatives decelerated the degradation process. Greater current efficiency and lower specific energy consumption were attained in sulfate medium at lower current density and higher azo dye content. A plausible reaction sequence based on 18 aromatic intermediates identified by GC-MS and 6 short-linear carboxylic acids detected by ion-exclusion HPLC has been proposed. The SPEF process promoted the photodegradation of Fe(III)-oxalate complexes and other undetected products. Sulfate and nitrate ions were always released to the medium.

Abstract
The decolorization and mineralization of solutions containing 230 mg L(-1) of the food azo dye Allura Red AC at pH 3.0 have been studied upon treatment by electrochemical oxidation with electrogenerated H2O2 (EO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF). Experiments were performed with a stirred tank reactor containing a boron-doped diamond (BDD) or Pt anode and an air-diffusion cathode to generate H2O2. The main oxidants were hydroxyl radicals formed at the anode surface from water oxidation and in the bulk from Fenton's reaction between H2O2 and added Fe(2+). The oxidation ability increased in the sequence EO-H2O2 < EF < PEF and faster degradation was always obtained using BDD. PEF process with BDD yielded almost total mineralization following similar trends in SO4(2-), ClO4(-) and NO3(-) media, whereas in Cl(-) medium, mineralization was inhibited by the formation of recalcitrant chloroderivatives. GC-MS analysis confirmed the cleavage of the −N=N− bond with formation of two main aromatics in SO4(2-) medium and three chloroaromatics in Cl(-) solutions. The effective oxidation of final oxalic and oxamic acids by BDD along with the photolysis of Fe(III)-oxalate species by UVA light accounted for the superiority of PEF with BDD. NH4(+), NO3(-) and SO4(2-) ions were released during the mineralization.

Abstract
OBJECTIVE We determined the risk factors and incidence of clinical events associated with suboptimal immune reconstitution (SIR) defined by an increase in CD4 inferior to 50 cells/μL, from inclusion up to six months of antiretroviral treatment (ARVT), in patients with an undetectable viral load (<50 copies/mL). METHODS Logistic regression and Cox's proportional hazards model were used to examine risk factors for SIR and the association between SIR and the risk of new clinical events or death, respectively after six months of ARVT. RESULTS One hundred and two (15.5%) of the 657 patients presented with SIR. Age > 40 years (aOR = 1.74, 95% CI = 1.10-2.75), baseline CD4 ≥ 100 cells/μL (aOR = 2.06, 95% CI = 1.24-3.42), ARVT including AZT (aOR = 4.57, 95% CI=1.06-19.76), and the occurrence of a severe opportunistic infection during the first semester of ARVT (aOR = 2.38 95% CI= 1.49-3.80) were associated with SIR. After six months of ARVT and up to seven years of follow-up, 39 patients with SIR had presented with an opportunistic infection or death (rate= 9.78/100 person-years) compared to 168 with a normal recovery (rate = 7.75/100 person-years) but the difference was not statistically significant (aHR = 1.22, 95% CI = 0.85 to 1.74). CONCLUSION SIR is less common in our country and is not associated with increased mortality or a greater incidence of opportunistic infections after six months of ARVT.

Abstract
Malaria remains a major problem in African countries despite substantial decreases in morbidity and mortality due to sustained control programs. Studies for the evaluation of qualitative or quantitative Ab responses to key targets of anti-plasmodium immunity were mostly done in rural endemic setting compared to urban area. In a cohort of 200 patients with mild malaria and living in Dakar, we analyze total and subclasses IgG responses to a panel of P. falciparum blood stage antigens: MSP1p19, MSP3, EB200, GST-5 and R23. A mean age of 15 yrs (4 to 56 yrs) and parasitemia between 0.1 to 17% were found. Levels of IgG anti-MSP3 were higher in patients with low parasitemia (≤1%) and appear negatively correlated to parasite densities (Rho =. 0.54; p= 0.021). This correlation is more significant in children (≤ 15 yrs). In addition, an increase of IgG responses against MSP1p19 is highly observed in adults having a parasitemia less than 1%. In those patients, we find that IgG1 subclasses were predominant (p <0.01). Our study shows an association between Ab responses and parasitemia. This association is dependant to IgG anti-MSP3 in children and IgG anti-MSP1p19 in adults living in urban area.

Abstract
OBJECTIVE The pathology of the salivary glands focuses on that of the parotid gland. The purpose of this study is to clarify and explain the epidemiological features of parotid tumors in a Senegalese context, to highlight the importance of clinical examination when access to complementary investigations is limited, to discuss respective indications and finally to describe certain aspects of treatment in our context. MATERIALS AND METHODS This retrospective study of 114 cases of parotidectomy spans 16 years, from 1992 to 2007. It was performed in the ENT department of University Hospital of Fann, Senegal. All patients operated on for chronic mass of the parotid region for whom histological results were available when initially included. Benign swellings were subsequently excluded. The study parameters were epidemiological, clinical, paraclinical and surgical. RESULTS The 114 parotidectomies showed a predominance of benign tumours: 63 procedures (55.26%) essentially concerned pleomorphic adenoma; 30 cases (26.31%) concerned malignant tumours, mainly parotid adenocarcinoma. There were 21 cases of benign swelling (18.4%). The study focused on the series of 93 cases of benign and malignant tumours of the parotid gland. Both sexes were affected similarly. All age groups were concerned, from 5 to 89 years. A total of 97% of patients underwent surgery: conservative total parotidectomy in 75.51% of cases. CONCLUSION Although there are features specific to the local context, the epidemiological profile of parotid tumours is well-known. Indications for complementary investigations are discussed, as availability in Senegal is restricted, highlighting the important role of clinical examination in the management of parotid tumours.

Abstract
PURPOSE To describe the epidemiological, anatomico-clinical and therapeutic aspects of the patent vaginoperitoneal canal (PVPC) in urological practice and to compare our results with those of pediatric teams. PATIENTS AND METHODS We performed a retrospective descriptive study of PVPC cases operated in a urology unit. The following parameters were studied: medical history, age, method of installation, the anatomo-clinical type, side and the results of the treatment. RESULTS A total of 163 cases were collected over a period of 5 years. The average age was 7.5 ± 7 years with a range of 2 months and 39 years. Thirty-four patients had less than or equal to age 2 ears and 28 patients were adults. The reason for consultation was an inguinal or scrotal inguinal, painless and intermittent swelling in 72.3% of cases. Installation mode was progressive in 45 patients (27.6%). The PVPC was sitting right in 81 patients (49.7%) and was bilateral in 12 patients (7.3%). The anatomo-clinical types were dominated by the communicating hydrocele (52%). The treatment was carried out in controlled surgery in all patients and the mean duration of hospitalization was 24 hours. The postoperative course was marked by 5 cases of scrotal hematoma and 2 cases of parietal suppuration. Postoperative mortality was zero. After a mean postoperative decrease of 2 years we observed 3 cases of testicular atrophy and two recurrences. CONCLUSION Our results in terms of morbidity and mortality although satisfactory were lower than those of pediatric teams. LEVEL OF EVIDENCE 5.

Abstract
Primitive neuroectodermal tumors are a rare type of malignant neuroectodermal tumor that is very aggressive. Cervicofacial location is rare, even exceptional. We report a case of a 4-month-old male infant, referred from the pediatric clinic for severe supralaryngeal dyspnea, a firm mass under the left mandibular angle, mobile and extended to the parotid area, painful, with a curve of the left side wall of the oropharynx. Cervical computed tomodensitometry showed a well-limited mass in the carotid area, enhanced by the contrast product. A vascularized mass, which had developed at the expense of the vagus nerve, was removed surgically. Histology found a primitive neuroectodermal tumor.

Abstract
OBJECTIVE Describe the epidemiology, diagnosis and treatment of vesicovaginal fistula (VVF). PATIENTS AND METHODS We conducted a retrospective descriptive study of all cases of VVF secondary to hysterectomy. The following parameters were studied: age, parity, indication for hysterectomy, risk factors, the consultation period, the anatomical type of VVF, the paraclinical, the surgical approach and results of the cure. RESULTS Fourteen cases were identified over 10 years. All hysterectomies were performed by laparotomia. The average age of patients was 54.3±13 years. Hysterectomy was performed in view of a uterine leiomyoma in eight cases, a cancer of the cervix in four cases, a menometrorrhagia in one case and a choriocarcinoma in one case. Four patients had received neoadjuvant radiotherapy. The mean time from injury was 13.5±18 months. Examination under valve was allowed to find 11 VVF type 1 and three type 2 VVF. IVU was normal in seven patients and allowed to find an ureterohydronephrose stage III in one patient. VVF was addressed by high in ten cases including 5 by transperitoneovaginale and 5 by transvesical pure. The postoperative course was uneventful in 11 patients (78%) but marked by vesicocutaneous fistula, parietal suppuration and one failure. CONCLUSION In this short series of post-hysterectomy VVF treated by laparotomia, we observed a rate of cure satisfying in spite of an important psychosocial morbidity.

Abstract
INTRODUCTION The management of coronary artery disease has made important progress. Adherence to therapeutic measures is a great challenge for improving the long-term prognosis. In this work, we evaluate factors related to therapeutic adherence in black African patients with stable coronary artery disease. METHODOLOGY We conducted a survey over three months (February-May 2008) in three cardiology departments in Dakar. We studied the regularity of drug intake, the adherence to the dietary advices and the appointments for consultation as well as the factors related to adherence. Good adherence was defined by a compliance rate greater or equal to 80% and a compliance rate less than 40% defined poor adherence. RESULTS We included 105 patients (61 men) with a mean age of 60.67±11.29 years. Good compliance was noted in 56.2% of cases for drug treatment, 42% for dietary advices and 65% for appointments for consultation. A history of acute coronary events (P=0.04), a good knowledge of the disease (P=0.03) and a healthcare (P=0.02) were the factors related to a good adherence to drug treatment, whereas ischemic cardiomyopathy was a factor for poor adherence (P=0.002). Knowledge of coronary disease was the only factor correlated with good adherence to lifestyle (P=0.014). CONCLUSION Therapeutic adherence remains unsatisfactory in Black African patients with stable coronary artery disease, hence the importance of patient education to reach a good adherence for therapeutic, because better adherence improves long-term prognosis of coronary artery disease.

Abstract
OBJECTIVES To evaluate the results of Anderson-Hynes open pyeloplasty in our institution. And then to compare them to those of laparoscopic procedure and identify what can be considered now as the indications of the open procedure. PATIENTS AND METHODS It was a retrospective study on 30 cases of ureteropelvic junction syndrome managed by Anderson-Hynes open procedure. The clinical, biological and radiologic characteristics of the patients as well as the surgical technique and its results were taken into account. The patients were classified, according to Valdeyer and Cendron classification as type II in eight cases (26.7%), type III in ten cases (33.3%) and type IV in four cases (13.3%). There were also eight cases of giant hydronephrosis (26.7%). The operating time, the length of hospital stay and the outcomes were studied and compared with those of the laparoscopic pyeloplasty found in the medical literature. RESULTS The mean operating time was 115 ± 33.4 minutes (90-230 min). The mean length of hospital stay was 10.4 ± 5.1 days. Six patients (20%) had postoperative complications. After a mean follow-up of 28 ± 13.7 months (13-48 months), our first-hand success rate was 90% (n=27). CONCLUSION Anderson-Hynes open pyeloplasty reached good results but nowadays its indications can be limited to laparoscopic contraindications, severe hydronephrosis (grade IV or giant hydronephrosis) and second-hand cases. The two latter indications depend on the surgeon experience in laparoscopic surgery.

Abstract
Résumé
Buts
décrire les aspects cliniques et thérapeutiques des cancers de la verge au Sénégal.
Patients et méthodes
nous avons effectué une étude rétrospective qui s’est intéressée aux dossiers des patients suivis pour cancer de la verge au service d’urologie du CHU Aristide Le Dantec entre janvier 2000 et décembre 2011.
Résultats
huit patients d’âge moyen de 51,5 ans avec des extrêmes de 27 à 77 ans ont été répertoriés. Ils étaient tous circoncis dans l’enfance. L’examen clinique avait mis en évidence une tumeur ulcérobourgeonnante intéressant le gland et une partie du corps de la verge dans cinq cas; dans deux cas, elle intéressait la totalité de la verge alors que seul un cas était limité au gland. Les patients étaient ainsi classés selon le système TNM 2002 de l’UICC en cT2 (quatre cas), cT3 (trois cas) et cT1 (un cas). Le type histologique de la tumeur était le carcinome épidermoïde chez tous les patients. Il n’y avait pas de localisation secondaire au scanner thoracoabdomino-pelvien. Sur le plan thérapeutique, une pénectomie partielle a été réalisée dans cinq cas, une pénectomie totale avec curage ganglionnaire dans un cas. Deux patients ont refusé le traitement chirurgical. Aucune récidive n’était notée chez les cinq patients ayant subi une amputation partielle du pénis. La survie globale était donc de 83,3 % pour les patients opérés.
Conclusion
le cancer de la verge est rare au Sénégal. La prise en charge est délicate du fait du diagnostic tardif avec des lésions évoluées, d’où l’importance d’une sensibilisation des populations.

Abstract
PURPOSE To report epidemiological, clinical and paraclinical features of pyonephrosis and describe current management methods in Senegal. PATIENTS AND METHODS This retrospective study includes a series of patients admitted for pyonephrosis to the Urology Department of the Aristide Le Dantec Hospital in Dakar between 1995 and 2009. The following information was collected for each patient: age, sex, clinical manifestations, diagnostic findings, treatment modalities and outcomes. RESULTS A total of 44 patients with a mean age of 34 years were included. The most common clinical manifestations were acute flank pain, sepsis and renal mass. Diagnostic was usually based on medical imaging, i.e., renal utrasonography and computed tomography. Urolithiasis was the underlying etiology in 73.2% of cases. Nephrectomy was performed in 83% of cases with or without preliminary nephrostomy catheterization. CONCLUSION Development of both diagnostic (medical imaging) and therapeutic methods for management of pyonephrosis has been consistent with the rarity of this condtion in Senegal.

Abstract
Résumé
Objectif
Étudier les aspects diagnostiques et thérapeutiques de la torsion du cordon spermatique (TCS) dans notre pratique quotidienne et faire une revue de la littérature.
Patients et méthodes
Étude rétrospective de janvier 2002 à décembre 2009 sur tous les cas de suspicion de TCS reçus en urgence.
Résultats
La TCS était confirmée chez 58 patients après scrototomie exploratrice. L’âge moyen des patients était de 21 ans (avec des extrêmes de 1 et de 44 ans) et 48 patients (83 %) étaient âgés de plus de 15 ans. Le délai moyen entre le début de la symptomatologie douloureuse et l’arrivée aux urgences était de 102 heures (avec des extrêmes de 2 et de 480 heures); 47 patients ont été reçus après la sixième heure et 19 patients ont été référés d’une structure périphérique. La torsion était supravaginale chez cinq sujets âgés de plus de 15 ans et était sanctionnée d’une orchidectomie chez 30 patients (52 %).
Conclusion
Notre série est caractérisée par un taux élevé de castration d’où l’intérêt de mettre l’accent sur la sensibilisation des populations qui doivent venir consulter en urgence devant une grosse bourse douloureuse aiguë.

Abstract
One of the concerns of the dental surgeon in the realization of any operational act is the durability of this one. The mechanical resistance of the provisional prostheses contributes in a large part to the durability of those. The resins in general, have weak mechanical properties. The purpose of this study is to evaluate the resistance in inflection of temporary bridges reinforced with glass fibre. To remedy the weak mechanical properties of resins, we thought in this study, to reinforce them with glass fibres. For this purpose, we realized with two different resins, four groups of temporary bridges of 3 elements, including two groups reinforced fibreglass and the others not. Tests of inflection 3 points have been made on these bridges and resistance to fracture was analysed. The statistical tests showed a significant difference in four groups with better resistance for the reinforced bridges.
