Reaction of dimethyl N-cyanodithioiminocarbonate, NCNC(SCH3)2 (L), and SnPh3Cl led to the formation of [ClPh3SnNCNC(SCH3)2] (1) which crystallizes in the monoclinic space group C2/c with Z=8, a=19.152(2) Å, b=12.8659 (16) Å, c=19.063(3) Å, β=108.608(3) and V=4451.6(10) Å3. The structure of 1 consists of a SnPh3 moiety trans-coordinated in apical positions by one L ligand, N-coordinated, and one chlorine atom involving a trigonal bipyramid geometry around the Sn(IV) atom. To our knowledge, this is the first isolation of a discrete triorganotin(IV) complex with a N-cyanodithioiminocarbonate adduct. The structural characterization of 1 was completed by infrared and nuclear magnetic resonance spectroscopy, and elemental analysis which confirm the X-ray elucidation.

Buts: rapporter les aspects cliniques et thérapeutiques de la maladie de Lapeyronie (MLP). Matériel et méthodes: étude descriptive monocentrique recrutant 17 cas de MLP dans un service d’urologie au Sénégal entre janvier et décembre 2012. L’âge des patients, les motifs de consultation, le délai de consultation, l’examen des plaques de fibrose, le degré de courbure, le traitement et ses résultats ont été analysés. Résultats: l’âge moyen était de 58,2 ans (33 et 80 ans). La courbure était la plainte la plus observée (13 patients/17) et isolée chez 4 patients. La douleur pénienne était observée chez 4 patients et la dysérection chez 7 patients. Le délai de consultation moyen était de 21,2 mois (1 et 72 mois). Le grand axe moyen des plaques de fibrose était 2,8 cm (0,5 et 7,5 cm). Le degré de courbure de la verge moyen était de 31,6 (0 et 95). Neuf patients ont reçu un traitement à base de vitamine E et des infiltrations de corticoïdes dans la plaque. Il a été efficace chez 3 patients vus à la phase inflammatoire. Un redressement satisfaisant de verge par plicature de l’albuginée des corps caverneux selon Nesbit a été réalisée chez 5 malades en phase de séquelle. Trois patients n’ont pas pu être opérés. Conclusion: la MLP a une faible prévalence et la plupart des patients consultent en phase de séquelle. Le traitement médical a été efficace à la phase inflammatoire et la chirurgie a permis de régler la courbure.

The title compounds [R2NH2][C2O4SnMe3](R=i-Bu, Cy), in which tin atoms adopt a distorted trigonal bipyramidal configuration, have been prepared and submitted to an X-ray diffraction study. These compounds have been obtained from the reaction of (Cy2NH2)2C2O4·H2O or (i-Bu2NH2)2C2O4 with SnMe3Cl. In both [R2NH2][C2O4SnMe3] compounds, the trans complex has an almost regular trigonal bipyramidal geometry around the tin atom. The SnMe3 residues are connected as a chain with bridging oxalate anions in a trans-SnC3O2 framework, the oxygen atoms being in axial positions. The cations connect linear adjacent chains through NH…O hydrogen bonds giving layered structures.

Background: There is no established standard of care for treating central centrifugal cicatricial alopecia (CCCA), and treatment approaches vary widely., Objective: To develop consensus statements regarding the use of various pharmacological therapies in treating adults with CCCA., Methods: We invited 27 dermatologists with expertise in hair and scalp disorders to participate in a 3-round modified Delphi study between January and March 2023. Statements met strong consensus if 75% of respondents agreed or disagreed. Statements met moderate consensus if 55% or more but less than 75% agreed or disagreed., Results: In round 1, 5 of 33 (15.2%) statements met strong consensus, followed by 9 of 28 (32.1%) in round 2. After the final round 3 meeting, strong consensus was reached for 20 of 70 (28.6%) overall statements. Two statements achieved moderate consensus., Limitations: This study included only English-speaking, US-based dermatologists and did not consider nonpharmacological therapies., Conclusion: Despite varying opinions among dermatologists, consensus was reached for several statements to help clinicians manage CCCA.

Background: Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia seen primarily in women of African descent but rarely reported in men. The etiology of CCCA is unknown, but genetic variants, type 2 diabetes mellitus, and bacterial infections may play a role., Objectives: We aimed to characterize the demographics, medical histories, and clinical findings of male patients with CCCA with the hypothesis that features may differ from women., Methods: This was a case series of adult male patients with biopsy-confirmed CCCA seen at an academic dermatology department between 2012 and 2022., Results: In total, 17 males had a scalp biopsy and clinical findings consistent with CCCA. The average age was 43 years, and 88.2% of cases identified as Black race. Scalp pruritus was the most common symptom, and few patients endorsed high-risk hair care practices. None of the cases had diagnosis of type 2 diabetes mellitus, but 17.6% had history of latent tuberculosis, and 47.1% had a positive family history of alopecia. We observed 8 patients with atypical CCCA, and 29.4% had an overlapping scalp diagnosis., Limitations: This study is limited by the single center, retrospective design and small sample size., Conclusions: It is important to consider CCCA in the differential diagnosis of alopecia in adult Black males., Competing Interests: Conflicts of interest None disclosed., (Copyright © 2023 American Academy of Dermatology, Inc.

Farmers' entrepreneurship is an important engine to comprehensively help promote rural revitalization. Based on data from the China Household Finance Survey (CHFS2019), this paper empirically examines the effect of digital literacy on farmers' entrepreneurial behavior using the Probit model and instrumental variable method; and examines the mediating role of health status in this effect using the mediation effect model, combined with the Sobel and Bootstrap tests. The results of the study showed that (1) digital literacy positively influenced farmers' entrepreneurial behavior at the 1% significant level, and this positive influence showed some differences across gender and age; (2) health status played a mediating effect in the positive influence of digital literacy on farmers' entrepreneurial behavior. Accordingly, policy recommendations are made to foster farmers' digital literacy, encourage farmers' entrepreneurship, and ensure farmers' "digital health" services., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Bai et al.

Aim: To evaluate the epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas (VVF) in university hospitals in Senegal., Patients and Method: This is a retrospective, descriptive, single-center study, collecting the records of patients followed for VVF between January 2014 and December 2019 at the Urology and Andrology Department of the Centre hospitalier universitaire Aristide Le Dantec, Dakar, Senegal. The following parameters were studied: age, geographical origin, parity, and etiology of VVF. To assess the evolution of the epidemiological and etiological profile of VVF, we compared our results with those of series published by our structure., Results: Forty-five (45) VVFs were identified over a period of 6 years. This represents an annual average of 7.5 fistulas. The average age was 40±15.13 years with extremes of 13 years and 75 years; 17 patients (37.8%) were older than 45 years. The average parity was 3 with extremes from 0 to 12 children. Multiparous women represented 68.8% of the patients. Obstetric VVF (OVF) was more frequent (48.9%) followed by iatrogenic VVF (33.3%). The mean age was higher in the IVF group compared to the VVF group (32 years) (P = 0.0004). Thirty patients were from the Dakar region and its suburbs (66.6%). The etiology of VVF did not vary according to the geographical origin of the patients (P=NS). VVF was frequently associated with the management of cervical cancer in 42.2% of cases. Comparison of our current data with previous series shows a reduction in the annual incidence of VVF. VVFs, although they have decreased significantly, are still predominant. There is a constant increase in the number of IVF., Conclusion: There is an evolution of the epidemiological and etiological profile marked by a decrease in the frequency of VVFs and an increase in that of IVFs. It is also worth noting the frequent association between cervical cancer and VVF., Level of Evidence: Level 4: retrospective study., (Copyright © 2023. Published by Elsevier Masson SAS.)

Background: The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants may have contributed to prolonging the pandemic, and increasing morbidity and mortality related to coronavirus disease 2019 (COVID-19). This article describes the dynamics of circulating SARS-CoV-2 variants identified during the different COVID-19 waves in Mali between April and October 2021., Methods: The respiratory SARS-CoV-2 complete spike (S) gene from positive samples was sequenced. Generated sequences were aligned by Variant Reporter v3.0 using the Wuhan-1 strain as the reference. Mutations were noted using the GISAID and Nextclade platforms., Results: Of 16,797 nasopharyngeal swab samples tested, 6.0% (1008/16,797) tested positive for SARS-CoV-2 on quantitative reverse transcription polymerase chain reaction. Of these, 16.07% (162/1008) had a cycle threshold value ≤28 and were amplified and sequenced. The complete S gene sequence was recovered from 80 of 162 (49.8%) samples. Seven distinct variants were identified: Delta (62.5%), Alpha (1.2%), Beta (1.2%), Eta (30.0%), 20B (2.5%), 19B (1.2%) and 20A (1.2%)., Conclusions and Perspectives: Several SARS-CoV-2 variants were present during the COVID-19 waves in Mali between April and October 2021. The continued emergence of new variants highlights the need to strengthen local real-time sequencing capacity and genomic surveillance for better and coordinated national responses to SARS-CoV-2., Competing Interests: None declared., (© 2022 The Author(s).)

Background: Patients with hidradenitis suppurativa (HS) experience high physical and emotional symptom burden and may benefit from palliative care interventions, though no studies have explored the unmet palliative care needs in this population., Objective: This case series aimed to qualitatively evaluate unmet needs and palliative care interventions among patients with HS who were referred to palliative care., Methods: We reviewed medical records of patients with HS who were referred from an HS specialty clinic and seen in an interprofessional palliative care ambulatory clinic. Palliative care notes were qualitatively analyzed inductively and deductively to identify themes characterizing unmet needs and palliative care interventions., Results: Thirteen patients with HS (median [IQR] age, 38 [31-45] years; 11 [85%] women; 11 [85%] Black) were referred and seen in a palliative care specialty clinic. Topics discussed included uncontrolled HS pain, housing insecurity, and emotional distress. Palliative care interventions included a thorough assessment of pain, multimodal pain management approaches, social worker weekly check-ins, and management of psychotropic medications., Limitations: Small study at a single tertiary center., Conclusions: Care models integrating palliative care approaches with multidisciplinary support services may reduce disease burden in a subset of patients with HS., Competing Interests: Dr Orenstein received grants from Pfizer.

In response to the COVID-19 pandemic, COVID-19 vaccines have been developed, and the World Health Oraganization (WHO) has granted emergency use listing to multiple vaccines. Studies of vaccine immunogenicity data from implementing COVID-19 vaccines by national immunization programs in single studies spanning multiple countries and continents are limited but critically needed to answer public health questions on vaccines, such as comparing immune responses to different vaccines and among different populations., Competing Interests: The authors have declared that no competing interests exist.

Farmland abandonment, as a manifestation of the low efficiency of the rural economy, has a profound impact on the process of agricultural and rural modernization. This study uses the 2016 China Labor Force Dynamic Survey data based on 8116 samples from 104 cities, constructs the Tobit model and IV Tobit model to analyze the land abandonment quantitatively from the perspective of environmental pollution. The results show that (1) environmental pollution can significantly increase the probability and area of land abandonment, (2) there is significant regional heterogeneity in the impact of environmental pollution on land abandonment, (3) the impact of environmental pollution on land abandonment varies significantly with different family sizes and land management scales, but the land management scale is relatively more sensitive. This study provides a deeper understanding of the relationship between environmental pollution and land abandonment in China and provides a basis for formulating relevant policies to strengthen the treatment of environmental pollution to solve the dilemma of land abandonment, which is of great practical significance to sustainable development of rural economy and the guarantee of food security in China., (© 2021.

The purpose of this study was to assess outcomes of radical prostatectomy in patients with prostate cancer. We conducted a retrospective single-center study in the Department of Urology and Andrology at the Aristide Le Dantec Hospital in Dakar from June 1, 2010 to May 31, 2016. We collected data of 60 patients undergoing radical retropubic prostatectomy associated with dissection of the iliac and obturator nodes. After radical prostatectomy, prostate specific antigen (PSA) levels were undetectable (<0.1 ng/mL) in 20 patients (33.3%). Eleven patients (18.3%), who had biochemical relapse, received complementary hormone therapy. Patients achieved a response after initiation of treatment, and total PSA became undetectable again after an 8-month follow-up period. Mean overall survival was 17.5 months, with a median of 9.49. Cumulative overall survival rates at 1 year, 3 years and 4 years were 42.4, 13.6 and 6.8%, respectively. Mean relapse-free survival was 17.3 months, with a median biochemical relapse-free survival of eleven (11) months. The mean duration of specific survival was 8.1 months, with a median of 3 months. Seven patients had positive resection margins (11.6%). Four patients had lymph node involvement. Radical prostatectomy, suggested in some patients with prostate cancer in our practice, has been shown to be an effective therapeutic method leading to good outcomes., Competing Interests: Les auteurs ne déclarent aucun conflit d´intérêts., (Copyright: Ndiaga Seck Ndour et al.)

Aim: to evaluate the results of two-level urethroplasty in the treatment of complex urethral strictures in our clinical center., Patients and Method: Thiswas a retrospective cross sectional study from January 2012 to September 2015 in our clinical center. Patients operated according to Bengt Johanson technique were included. The parameters studied were age, the urological history, consultation reasons, duration of evolution, stenosis characteristics and treatment outcomes., Results: twelve patients were enrolled in our study. The mean age was 48 ± 20 years. The main reason consultation reason is urine retention. The mean duration of evolution was 30 ± 25 months. The most common etiology identified was scleroinflammatory one . All the patients already had at least one medical background. The physical examination showed a periurethral gangue in 10 patients. The mean length of the urethral stricture was 6.3 ± 2.2 cm. After an average follow-up of 3.8 ± 2.3 months; the treatment outcomes were considered satisfactory in 8 patients and bad in 4 patients., Conclusion: Bengt Johanson's two level urethoplasty gives good outcomes in the treatment of complex urethral strictures., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Background: Although several experimental therapeutics for Ebola virus disease (EVD) have been developed, the safety and efficacy of the most promising therapies need to be assessed in the context of a randomized, controlled trial., Methods: We conducted a trial of four investigational therapies for EVD in the Democratic Republic of Congo, where an outbreak began in August 2018. Patients of any age who had a positive result for Ebola virus RNA on reverse-transcriptase-polymerase-chain-reaction assay were enrolled. All patients received standard care and were randomly assigned in a 1:1:1:1 ratio to intravenous administration of the triple monoclonal antibody ZMapp (the control group), the antiviral agent remdesivir, the single monoclonal antibody MAb114, or the triple monoclonal antibody REGN-EB3. The REGN-EB3 group was added in a later version of the protocol, so data from these patients were compared with those of patients in the ZMapp group who were enrolled at or after the time the REGN-EB3 group was added (the ZMapp subgroup). The primary end point was death at 28 days., Results: A total of 681 patients were enrolled from November 20, 2018, to August 9, 2019, at which time the data and safety monitoring board recommended that patients be assigned only to the MAb114 and REGN-EB3 groups for the remainder of the trial; the recommendation was based on the results of an interim analysis that showed superiority of these groups to ZMapp and remdesivir with respect to mortality. At 28 days, death had occurred in 61 of 174 patients (35.1%) in the MAb114 group, as compared with 84 of 169 (49.7%) in the ZMapp group (P = 0.007), and in 52 of 155 (33.5%) in the REGN-EB3 group, as compared with 79 of 154 (51.3%) in the ZMapp subgroup (P = 0.002). A shorter duration of symptoms before admission and lower baseline values for viral load and for serum creatinine and aminotransferase levels each correlated with improved survival. Four serious adverse events were judged to be potentially related to the trial drugs., Conclusions: Both MAb114 and REGN-EB3 were superior to ZMapp in reducing mortality from EVD. Scientifically and ethically sound clinical research can be conducted during disease outbreaks and can help inform the outbreak response.

Introduction: Endoscopic sinus surgery (ESS) is the mainstay for treatment of chronic rhinosinusitis versus maximal medical therapy. We propose a more economical option, by using steroid-impregnated Gelfoam instead of Nasopore post ESS, as it is less expensive and has showed effectiveness in preventing post-operative bleeding., Materials and Methods: A randomised, double-blinded, placebo-controlled trial was carried out in eight patients with chronic rhinosinusitis or nasal polyposis who were planned for bilateral endoscopic sinus surgery. A Peri-operative Sinus Endoscopy (POSE) Score and Lund-Kennedy Endoscopic Score (LKES) were recorded. The use of hydrocortisone-impregnated Gelfoam dressing versus normal saline-impregnated Gelfoam dressing were compared. Scores were repeated post-operatively at one week, three weeks and three months interval., Results: For LKES, at the end of three months, 50% of the patients had the same score difference, 37.5% had better results on the study side while 12.5% had better results on the control side. Meanwhile, for POSE Score, at the end of three months, 75% of the patients had better score difference on the study side while 12.5% had better results on the control side., Conclusion: Gelfoam can be used as nasal packing material to deliver topical steroid after endoscopic sinus surgery. Steroid-impregnated nasal dressing after endoscopic sinus surgery may not provide better long-term outcome.

Penile strangulation is a clinical condition requiring emergency management. Several metallic or non-metallic objects can be placed around the penis to improve sexual performance or for auto-erotic purposes. We report the case of two schizophrenic patients aged 25 and 33years hospitalized in the Emergency Department due to penile strangulation by metal ring. The ring was placed at the level of the glans foreskin groove 3 days before in one case and at the level of the root of penis 2 days before in the other. There was no urinary disorder in both patients. Ring ablation was performed with taxis under local anesthesia in one case and under sedation followed by double ring section using an electric saw in the other case.

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., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

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., (Copyright © 2014 Elsevier Masson SAS.

Scrotal calcinosis is a rare pathology and etiology still discussed. We report five cases in patients without particular history of another disease. Clinical examination revealed scrotal wall with painless nodules of various sizes producing a whitish substance, pasty. The phosphate levels were normal in all patients. They all had a resection of the lesions associated with scholarships plasty recovery. Histopathological study revealed calcified epidermoid cysts in 4 cases., (Copyright © 2013 Elsevier Masson SAS.

The title compound, [Sn(CH3)2Cl2(CH4N2S)2], crystallizes with two half-mol-ecules in the asymmetric unit. Both mol-ecules are completed by inversion symmetry with the two Sn(IV) atoms located on inversion centers. The metal atoms have distorted octa-hedral coordination environments defined by two Cl atoms, two C atoms of methyl groups and two thio-urea S atoms. In the crystal, mol-ecules are linked via N-H⋯Cl and N-H⋯S hydrogen bonds, forming a three-dimensional structure.

Bilharzioma are inflammatory pseudotumors, which often pose the problem of differential diagnosis with neoplastic processes. Using the keywords "testicular" and "schistosomiasis", there are only 14 cases of testicular bilharzioma identified on PubMed. The authors report two new cases in a 6-year-old child and an adult of 38 years, collected over a period of 5 years. In both cases, orchidectomy was performed and histological analysis of the surgical specimen was allowed to diagnose testicular bilharzioma by Schistosomia haematobium. The authors emphasize the need to evoke a bilharzioma before any testicular nodule in a patient living in an endemic area., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

The title compound, [Sn(C6H5)2Cl2(CH4N2S)2], has been obtained from the reaction between Sn(C6H5)2Cl2 and SC(NH2)2. The asymmetric unit consists of one half of the mol-ecular unit, the remainder generated by a twofold rotation axis located along the Cl-Sn-Cl bonds. The Sn(IV) atom is coordinated by two phenyl groups, two Cl atoms and two thio-urea ligands in an all trans octa-hedral C2Cl2S2 environment. Individual mol-ecules are connected through N-H⋯Cl hydrogen bonds, leading to a three-dimensional network structure. Intra-molecular N-H⋯Cl hydrogen bonds are also present.

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., (Copyright © 2013 Elsevier Masson SAS.

The Sn(IV) atom in the title compound, [(CH(3))(4)N][Sn(C(2)O(4))Cl(3)(H(2)O)]·H(2)O, obtained from the reaction between SnCl(4) and [(CH(3))(4)N](2)C(2)O(4)·2H(2)O, is six-coordinated by three Cl atoms, an O atom of a water mol-ecule and two O atoms from an asymmetrically chelating oxalate anion. The environment around the Sn(IV) atom is distorted octa-hedral. The anions are connected by the lattice water mol-ecule through O-H⋯O hydrogen bonds, leading to a layered structure parallel to (010). The cations are located between these layers and besides Coulombic forces are connected to the anionic layers through weak C-H⋯O and C-H⋯Cl inter-actions.

The Sn(IV) atom in the centrosymmetric title complex, [Sn2(CH3)4(NCS)2(OH)2], adopts a distorted trigonal-bipyramidal coordination environment defined by two methyl C atoms and one bridging hydroxide group in the equatorial plane while the other bridging hydroxide group and the N atom of the thio-cyanate anion are in the apical >positions. The dinuclear species are linked through O-H⋯S and C-H⋯ S hydrogen-bonding inter-actions into a three-dimensional network.

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., (Copyright © 2012 Elsevier Masson SAS. All rights reserved.)

The asymmetric unit of the binuclear title compound, [Sn(2)(C(2)O(4))(C(6)H(5))(6)(CH(4)N(2)S)(2)], consists of one half of the organotin(IV) mol-ecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The Sn(IV) atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thio-urea and the monodentately bridging oxalate anion in axial positions. The mol-ecules are linked through N-H⋯O hydrogen bonds involving the amino group of the thio-urea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-H⋯O inter-actions are also present.

The title salt, [(CH(3))(2)NH(2)][Sn(C(6)H(5))(3)Cl(2)], was obtained as a by-product of the reaction between bis-(dimethyl-ammonium) oxalate and triphenyl-tin chloride. In the stannate anion, the trigonal-bipyramidal coordination environment of the Sn(IV) atom is defined by the phenyl groups in equatorial and the Cl atoms in axial positions. The cations are connected to adjacent anions through N-H⋯Cl and C-H⋯Cl hydrogen-bonding inter-actions, leading to a chain motif parallel to [100].
