Abstract
INTRODUCTION Ureteroscopy (URS) can be proposed as first-line therapy for the management of pelvic stones from 10 to 20 mm and for lower ureteric stones in children. However, little is known about the success and the morbidity of URS in young children. Ureteroscopic treatment may present matters in young children because of the small size of the pediatric kidney and the small size of the collecting system. OBJECTIVE To assess safety and efficacy of URS for the treatment of urinary stones in children aged of 5 years or less. STUDY DESIGN After the institutional ethical board approval was obtained, we conducted a retrospective, analytic, multicentric study that included all URS performed between January 2016 and April 2022 in children aged of 5 years or less. In this non-comparative case series, anonymized pooled data were collected from 7 tertiary care centers of pediatric patients. Endpoints were the one-session SFR at 3 months and per and postoperatives complications. Descriptive statistics were applied to describe the cohort. RESULTS Eighty-three patients were included. For them, 96 procedures were performed at the median age of 3.5 years (IQR: 0.8-5) and median weight of 14 Kg (6.3-23). Median stone size was 13 mm (4-45). There were 65 (67 %) renal stones treated with flexible URS, most of which were in the renal pelvis (30 %) and in the lower calix (33 %). A ureteral access sheath was used in 91 % procedures. Preoperative ureteral stent was placed in 52 (54 %) of patients. None of patients had ureteral dilatation. The single-session SFR was 67.4 % (56.3 and 89.2 % for flexible URS and semi-rigid URS respectively) and children require 1.4 procedures to achieve complete stone clearance. The overall complication rate was 18.7 %, most of them were minor (Clavien I-II). Intraoperative perirenal extravasation (Clavien IIIb) due to forniceal rupture was documented in 6.2 % of cases, related to an increased intrapelvic pressure (IPP) performed in a closed pelvicalyceal system. DISCUSSION Pediatric urologists should be aware of forniceal rupture based on the presence of extravasation of contrast during endourological procedures especially when they have difficulties to reach lower caliceal stone in small patient. CONCLUSION URS in patients aged of 5 years or less, is a complex minimally invasive procedure with reasonable efficacy and low morbidity. Intrarenal stones treated by RIRS in young children carries the risk of additional procedures to complete stone clearance.

Abstract
The long-held belief that animal-mediated pollination is absent in the sea has recently been contradicted in seagrasses, motivating investigations of other marine phyla. This is particularly relevant in red algae, in which female gametes are not liberated and male gametes are not flagellated. Using experiments with the isopod Idotea balthica and the red alga Gracilaria gracilis, we demonstrate that biotic interactions dramatically increase the fertilization success of the alga through animal transport of spermatia on their body. This discovery suggests that animal-mediated fertilization could have evolved independently in terrestrial and marine environments and raises the possibility of its emergence in the sea before plants moved ashore.

Abstract
BACKGROUND Boys with posterior urethral valves (PUVs) have an increased risk of febrile urinary tract infections (fUTIs). Circumcision is believed to reduce the risk of fUTIs in boys, although there are no randomized trials demonstrating this. OBJECTIVE To determine the effect of circumcision on the risk of fUTIs in boys with PUVs. DESIGN, SETTING, AND PARTICIPANTS A clinical randomized trial that ran between August 2012 and July 2017 was conducted. The trial was multicentric, including 13 referral centers for pediatric urology. Male boys, aged 1-28 d, diagnosed with posterior urethral valves, confirmed by voiding cystogram, were included. The exclusion criteria included presence of a genital malformation contraindicating performing a circumcision. INTERVENTION Participants were randomized to neonatal circumcision + antibiotic prophylaxis (CATB) or antibiotic prophylaxis alone (ATB), and followed for 2 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was a risk of presenting fUTIs in each group. An fUTI was defined as fever (>38.5 °C) with evidence of pyuria and culture-proven infection on urinalysis, obtained by urethral catheterization or suprapubic aspiration. A bivariate analysis of the primary outcome was performed using the Kaplan-Meier method. RESULTS AND LIMITATIONS In total, 91 patients were included: 49 in group CATB and 42 in group ATB. The probability of presenting an fUTI was 20% in group ATB versus 3% in group CATB. The hazard ratio of presenting an fUTI within 2 yr in the ATB group compared with that in the CATB group was 10.3 (95% confidence interval: 1.3-82.5). Sixty-four children (70.3%) had a complete follow-up at 2 yr of age. CONCLUSIONS Circumcision significantly decreases the risk of presenting an fUTI in boys with PUVs. PATIENT SUMMARY In this report, we compared, in a multicentric trial, the number of febrile urinary tract infections (UTIs) in boys with posterior urethral valves who had either antibiotic prophylaxis alone or antibiotic prophylaxis and circumcision. We found that those who had a circumcision had a significantly lower risk of febrile UTIs.

Abstract
BACKGROUND Tuberous Breast Deformity (TBD) is a complex breast malformation: shape, size and symmetry of breast can be affected. It causes physical and mental suffering with significant effect on life quality. The purpose of this study is to assess patients satisfaction and patients quality of life after TBD surgery over time. METHODS All TBD patients operated between January 2007 and December 2018 were retrospectively identified for the study and those treated whith implant and/or mammoplasty were included. Different parameters have been recorded: age, malformation severity, breast symmetry, BMI, pregnancies, breast-feeding, type of primary surgery, complications and number of re-operations. Long-term satisfaction was assessed thanks to a BREAST-Q questionnaire (with a special « augmentation » or « reduction/mastopexy » module according to the primary surgery). RESULTS Eighty-two patients were included: 35 patients had recieved bilateral breast implants, 14 patients had received unilateral breast implant with or without collateral mammoplasty, and 33 patients had undergone breast reduction surgery. The total average for the medical follow-up was 7.4 years. The number of intervention was significantly higher for patients who had undergone breast augmentation surgery (P=0.001) and for patients with severe TBD (P=0.01). Forty patients replied to the BREAST-Q questionnaire. Patients satisfaction scores were not significantly different between the different groups. Regarding life quality scores, patients undergoing a breast augmentation surgery with bilateral implants seemed to have a better "sexual well-being" score (P=0.03). "Physical well-being" score was lower for patients who had a breast reduction compared to the other groups (P=0.01). Patients with breast implants had significant better quality of life scores, especially for the following parameters: "psychosocial well-being" (P=0.02), "sexual well-being" (P<0.001), "physical well-being" (P<0.001) and "satisfaction with breast" (P=0.03). CONCLUSIONS TBD surgery basically provides long-term satisfaction for most of the patients. The number of re-operations does not seem to deteriorate satisfaction over time.

Abstract
Molecular scattering at collisional energies of the order of 10-100 cm^{-1} (corresponding to kinetic temperatures in the 15-150 K range) provides insight into the details of the scattering process and, in particular, of the various resonances that appear in inelastic cross sections. In this Letter, we present a detailed experimental and theoretical study of the rotationally inelastic scattering of ground-state ortho-D_{2}O by ground-state para-H_{2} in the threshold region of the D_{2}O(0_{00}→2_{02}) transition at 35.9 cm^{-1}. The measurements were performed with a molecular crossed beam apparatus with variable collision angle, thence with variable collisional energy. Calculations were carried out with the coupled-channel method combined with a dedicated high-level D_{2}O-H_{2} intermolecular potential. Our theoretical cross section 0_{00}→2_{02} is found to display several resonance peaks in perfect agreement with the experimental work, in their absolute positions and relative intensities. We show that those peaks are mostly due to shape resonances, characterized here for the first time for a polyatomic molecule colliding with a diatom.

Abstract
Modeling of the observational spectra of H3O+ allows for a detailed understanding of the interstellar oxygen chemistry. While its spectroscopy was intensively studied earlier, our knowledge about the collision of H3O+ with the abundant colliders in the interstellar medium is rather limited. In order to treat these collisional excitation processes, it is first necessary to calculate the potential energy surface (PES) of the interacting species. We have computed the five-dimensional rigid-rotor PES of the H3O+-H2 system from the explicitly correlated coupled-cluster theory at the level of singles and doubles with perturbative corrections for triple excitations [CCSD(T)-F12] with the moderate-size augmented correlation-consistent valence triple zeta (aug-cc-pVTZ) basis set. The well depth of the PES is found to be rather large, about 1887.2 cm-1. The ab initio potential was fitted over an angular expansion in order to effectively use it in quantum scattering codes. As a first application, we computed dissociation energies for the different nuclear spin isomers of the H3O+-H2 complex.

Abstract
An electron beam, characterized by a high-angular discrimination (≃0.7°), has been used to measure the total (elastic plus inelastic) cross section of H_{2}O in the energy range 3-100 eV. Broad coincidence is found with recent experiments, including a pronounced shoulder in the 6-12 eV region. However, at energies ≲6 eV, the present cross sections are ≃30% higher. Furthermore, forward scattering has been probed in the angular range 0°-3.5° and measures of the average (rotationally and vibrationally summed) differential elastic cross sections for incident energies ≤12 eV are obtained at a scattering angle ≃1^{∘}. The measurements, which provide the first test of theoretical predictions in an angular region experimentally unexplored until now, are found to be within 1 standard deviation of corresponding ab initio R-matrix calculations.

Abstract
INTRODUCTION Paediatric recurrent epididymitis is frequently observed in several urogenital conditions, and may result in deterioration of long-term fertility. The management of recurrent epididymitis is still a therapeutic challenge for paediatric urologists, and as yet there is no consensus for treatment. OBJECTIVE To present a minimally invasive endoscopic approach for the treatment of recurrent epididymitis (more than three episodes). PATIENTS AND METHODS Eleven boys were referred with a history of recurrent epididymitis in a context of urogenital malformations. All children underwent endoscopic transurethral injection. Dextranomer/hyaluronic acid was injected around the ejaculatory ducts at the verumontanum (Summary Fig.). The medical records and outcomes of the patients were retrospectively reviewed. RESULTS Of the 11 boys, two (18%) had a history of bladder exstrophy, three (27%) anorectal malformation, two (18%) peno-scrotal hypospadias, two (18%) posterior urethral valves, one (9%) seminal vesicle cyst, and one (9%) urethral stricture. The median age at injection was 3.75 years (range 8 months-14.7 years). Endoscopic injection effectively prevented recurrence in eight patients (73%) with a mean follow-up of 3 years (range 6 months-8.8 years). The mean injected volume was 0.7 ml/session. No perioperative complications were recorded. Vas clipping was performed in three patients after unsuccessful injections. DISCUSSION The current discussion for management of recurrent epididymitis is mainly based on vas clipping. Endoscopic injection in the verumontanum could offer several potential advantages over vas clipping; moreover, it is easy to perform for an urologist who usually uses endourological approaches. It is believed that only Kajbafzadeh et al. have reported their experience with endoscopic injection in the verumontanum in seven patients with structural anomalies, and they had a 42% success rate. Similarly, the current study did not observe perioperative or postoperative complications. CONCLUSION In this series, endoscopic injection of the verumontanum was considered to be a safe and effective treatment in almost 73% of children with recurrent epididymitis. It did not result in perioperative complications and not contraindicate a subsequent surgical procedure such as vas clipping.

Abstract
OBJECTIVES Peritoneal dialysis (PD) is the modality of choice for children with end-stage renal disease (ESRD) awaiting renal transplant; however, this option is sometimes avoided for those with previous laparotomy. The goal of this study was to compare the outcomes of PD in patients with and without previous laparotomy. PATIENTS AND METHODS Twenty-four patients who had been started on peritoneal dialysis were retrospectively analysed. Group LAP consisted of six patients with previous laparotomy, and Group NO-LAP of 18 controls with either retroperitoneal or no abdominal surgery. The percentage of theoretical maximum volume of infusion, time to reach it, complications (infection and drainage difficulties), and number of catheters needed to finish therapy were analysed. RESULTS The characteristics of patients and technique of insertion are presented in Table. The percentage of maximum theoretical volume of infusion was similar in both groups. Median of catheter survival was similar in both groups. Complications were divided into malfunction (slow drainage, obstruction or leak) and infection. Incidence of complications per catheter and per month of dialysis was ten times lower in Group NO-LAP. Peritoneal dialysis failed in one patient with recurrent intraperitoneal adhesions after adhesiolysis in Group LAP. CONCLUSION Despite a higher incidence of complications (malfunction and infections), PD remains an acceptable option after laparotomy. In this series, it was sufficient in achieving adequate filtration in five patients.

Abstract
BACKGROUND Odontoid fractures are the most common upper cervical spine fracture in adults over 70 years of age. Hence, treatment of these fractures has public health implications. OBJECTIVES Evaluate the early complications, bone healing and mortality in patients above 75 years of age who undergo surgical treatment of an odontoid fracture. Compare the results between patients operated with the Harms technique or anterior screw fixation. METHODS This was a retrospective study of 70 patients with an odontoid fracture who were treated surgically between 2000 and 2015 at the Hôpital de la Timone in France. The age at the time of diagnosis, comorbidities, ASA score and autonomy were evaluated. Bone healing was determined using computed tomography. RESULTS In the cohort, 22 patients underwent anterior screw fixation, 38 were treated using the Harms technique and 10 with other procedures. The average age was 85.1 years. Fifty-four percent of patients had an ASA score above 3. The average follow-up was 23.4 months. An Anderson type II fracture was present in 80.6% of patients. In the anterior screw fixation group, the operative time was significantly shorter than in the Harms group and no blood transfusions were needed. However, 13.6% of these patients had to be re-operated because the initial construct was unstable; no patients in the Harms group underwent revision surgery. There were more complications in the anterior screw fixation group than in the Harms group: 41% versus 13.2% (P<0.02). The fractures had healed in all patients reviewed after 1 year. The 3-month survival in the anterior screw fixation group was 64.7% and it was 81.3% in the Harms group. These rates were stable at 1 year with no statistical differences between groups. CONCLUSION Surgical treatment of odontoid fractures in the elderly results in an excellent union rate. The mortality rate is stable after 3 months. In our experience, the Harms technique has a lower risk of complications and better mechanical stability than anterior screw fixation. Despite the steep learning curve, we believe the Harms technique is probably the best choice for treating odontoid fractures in the elderly. LEVEL OF EVIDENCE IV.

Abstract
We present a detailed theoretical study of the rotational excitation of CH+ due to reactive and nonreactive collisions involving C+(2P), H2, CH+, H and free electrons. Specifically, the formation of CH+ proceeds through the reaction between C+(2P) and H2(νH2 = 1, 2), while the collisional (de)excitation and destruction of CH+ is due to collisions with hydrogen atoms and free electrons. State-to-state and initial-state-specific rate coefficients are computed in the kinetic temperature range 10-3000 K for the inelastic, exchange, abstraction and dissociative recombination processes using accurate potential energy surfaces and the best scattering methods. Good agreement, within a factor of 2, is found between the experimental and theoretical thermal rate coefficients, except for the reaction of CH+ with H atoms at kinetic temperatures below 50 K. The full set of collisional and chemical data are then implemented in a radiative transfer model. Our Non-LTE calculations confirm that the formation pumping due to vibrationally excited H2 has a substantial effect on the excitation of CH+ in photon-dominated regions. In addition, we are able to reproduce, within error bars, the far-infrared observations of CH+ toward the Orion Bar and the planetary nebula NGC 7027. Our results further suggest that the population of νH2 = 2 might be significant in the photon-dominated region of NGC 7027.

Abstract
Lumbo-sacral (L5-S1) fusion is a widely performed procedure that has become the reference standard treatment for refractory low back pain. L5-S1 is a complex transition zone between the mobile lordotic distal lumbar spine and the fixed sacral region. The goal is to immobilise the lumbo-sacral junction in order to relieve pain originating from this site. Apart from achieving inter-vertebral fusion, the main challenge lies in the preoperative determination of the fixed L5-S1 position that will be optimal for the patient. Many lumbo-sacral fusion techniques are available. Stabilisation can be achieved using various methods. An anterior, posterior, or combined approach may be used. Recently developed minimally invasive techniques are gaining in popularity based on their good clinical outcomes and high fusion rates. The objective of this conference is to resolve the main issues faced by spinal surgeons in their everyday practice.

Abstract
A joint crossed beam and quantum mechanical investigation of the rotationally inelastic collisions of CO with ortho- and para-D2 molecules is reported. A new 4D potential energy surface (PES) averaged over the ground vibrational states of D2 and CO is used to calculate the rovibrational bound states of the ortho-D2-CO complexes. Close coupling calculations are then performed in the rigid rotor approximation for ortho- and para-D2 colliding with CO for the experimentally investigated transition of CO (j = 0 → 1) and for collision energies ranging from 0.1 to 25 cm-1. The agreement between theory and experiment is found to be very good for both the bound state energies of the ortho-D2-CO complexes and for the inelastic scattering cross-sections showing that the free rotation of two rigid rotors is a very good model of the D2-CO system in this low collision energy domain.

Abstract
INTRODUCTION Posterior urethral valves (PUV) are among the most common urological causes of chronic kidney disease (CKD) in childhood. Recently, genomic imbalances have been cited as potential risk factors for altered kidney function and have been associated with CKD. The phenotypic effects of a copy number variant (CNV) in boys with PUV are unknown. Here, it was hypothesised that the progression to early renal failure in PUV patients may be influenced by genetic aberrations. OBJECTIVE To assess the relationship between CNVs and renal outcomes. PATIENTS AND METHODS Between September 2012 and July 2015, 45 children with PUV were recruited to evaluate the presence of CNVs in their DNA. The patients' medical records were retrospectively reviewed. The criteria for outcomes of renal function included: assessments of the nadir serum creatinine in the first year of life, the estimated glomerular filtration rate at 1 and 5 years, and the requirement for renal replacement. RESULTS Thirteen CNVs were identified in 12 boys (29% of the cohort). Microarray analysis revealed two pathogenic CNVs (well-established CNVs known to be associated with genetic disease) and 11 of unknown significance (CNVs with insufficient current available evidence for unequivocal determination of clinical significance), including genes that have been previously implicated in kidney diseases and urogenital disorders. The median follow-up was 10.2 years (range 3-17.5) in the group of patients with CNV compared with 5.8 years (range 1-16.6) in those CNV-. The nadir creatinine values were significantly higher in boys with CNVs than in those without CNVs (57.5 μmol/L (range 23-215) and 28 μmol/L (range 18-155), respectively (P = 0.05) (Figure). Boys CNV+ had a worse prognosis, with a higher incidence of Stage-V CKD compared with the control group (33% with CNVs vs. 9% in CNV-, P = 0.06) at a median age of 22 months (range 8 months-16 years). Four (33%) patients CNV+ underwent renal transplantation. DISCUSSION The role of CNVs in the deterioration of renal function remains unknown. It can be hypothesised that CNVs could be a contributing factor or may serve as an accelerant for the progression to renal failure. CONCLUSION The CNVs >100 Kb were significantly associated with early onset renal failure in children with PUV. Prenatal detection of CNV could help to identify foetuses at high risk of severe renal impairment in cases of suspected PUV, especially in cases without oligohydramnios or severe pulmonary hypoplasia. These preliminary results should be confirmed in a larger cohort of patients.

Abstract
INTRODUCTION Despite many advances, the management of renal stones - especially lower caliceal stones (LCS) - remains a challenge. The gravity-dependent location of the lower calices hinders the spontaneous clearance of fragments, which can be a nidus for future growth and symptomatic recurrence. Currently, there is no standard adjunctive therapy to facilitate fragment passage. OBJECTIVES To report the safety and effectiveness of mechanical percussion diuresis and inversion (PDI) therapy for eliminating renal stones in children. PATIENTS AND METHODS Since November 2013, children with residual fragments (after shock wave lithotripsy or flexible ureteroscopy) or native symptomatic renal stones were prospectively included in a protocol of four PDI sessions. After giving written consent, the children drank 10 ml/kg of water 30 min before therapy. They then laid in a prone Trendelenburg position on a couch angled at 45° and received continuous 10-min mechanical percussion applied over the affected flank by a physiotherapist (Figure summary). Tolerance stone burden reduction and stone clearance were documented with ultrasound 4 weeks after the last session. RESULTS Seventeen participants, with a median age of 10.8 years (range 18 months to 18 years), received 82 PDI sessions performed over 22 months. The median stone diameter was 5 mm (range 3-9). All children tolerated the PDI therapy well. Over a median follow-up of 11 months (range 3-18), no significant adverse effects were noted. The overall stone-free rate was 65%. Four of the six patients with residual fragment passed their fragments. The patients who did not become stone free by PDI experienced a decrease in fragment size of 57% (range 34-71). The observance rate was 100%. DISCUSSION Many studies have demonstrated that the gravity-dependent position of the lower calyces appears to be an important factor limiting the clearance of LCS. Positioning patients with a degree of inversion in order to put the collecting system beyond the horizontal plane affected the LCS through gravitational force. Complications were rare. PDI appeared to save costs and have similar success rates as shock wave lithotripsy for native small renal stones in children. CONCLUSION PDI is safe and effective for facilitating gravity-dependent drainage of renal stones and provides an opportunity to treat children in a quick, non-invasive, economic, painless, non-radiative and diverting fashion. This therapy is a valuable alternative in the pattern of stone management. In case of persistent fragments, it is recommend that the number of sessions be increased to six.

Abstract
The patency of the naso-frontal duct is a key issue in the surgical management of chronic frontal sinusitis. Most of the current operative techniques only provide access to the paramedian portions of the frontal sinus. A canalization approach that allows a functional frontal sinus to be maintained while providing good access to the most lateral areas of the sinus is described herein. Two cases of severe post-traumatic frontal sinusitis, operated on successfully by canalization method based on the conservation of the frontal sinus and the maintenance of the patency of the naso-frontal duct, using both open and endonasal approaches, are reported. One patient was followed-up for 8 years and the other for 7 months. Canalization requires validation in a larger series. This approach provides an alternative to both cranialization and strictly endoscopic methods in lateralized frontal sinus retentions and allows mucocele to be avoided.

Abstract
AIM To our knowledge, the proportion of active tuberculosis diagnosed after 12-18 months during a screening tuberculosis process in a specialized centre (centre de lutte antituberculeuse [CLAT]) has not been described in France. The majority of other countries do not have any recommendation to screen at this time. METHODS We evaluated the number of treated or not treated latent tuberculosis infections (LTI) identified during tuberculosis screening. We identified the causes of ITL non-treatment, the number of active disease cases and the proportion of subjects lost to follow-up after 12-18 months. RESULTS Among the 1066 contact subjects, 159 (15 %) had a positive QuantiFERON-TB-Gold In-Tube(®) test. A prophylactic treatment with Rifinah(®) was given to 97 (61 %) subjects, 7 (7.3 %) having developed side effects that led to treatment interruption. A high proportion (56 %) of contact subjects were lost of follow-up and the main reason for no prophylactic treatment (20/52, 38 %) was due to these losses. No active disease cases were identified among the 474 (44 %) contact subjects who had a chest X-ray after 12-18 months follow-up by the CLAT. The low level of positive QuantiFERON-TB-Gold In-Tube(®) tests (15 %) could be explained by the high specificity of this test and the strong proportion of occupational contacts, of whom a probably significant number were not exposed to active disease. CONCLUSION The absence of active disease at 12-18 months and a majority (56 %) of contact subjects lost from follow-up at this period let us propose not to recall contact subjects at 12-18 months with the exception of those living under the same roof as the index case and/or those having a cumulative contact time of greater than 100 hours during the theoretical infectious period. This proposal remains to be confirmed by other studies, particularly including possible secondary cases diagnosed outside the screening periods by the CLAT.

Abstract
OBJECTIVE The aim of the present study was to validate an experimental model of heterotopic renal allotransplantation. Such a model, more relevant to the human situation, has never been previously described. MATERIALS AND METHODS Pietrin pigs (40 to 50 kg) were used in the study. Through a midline incision, the left kidney was removed, washed, and preserved in a standard preservation solution (Celsior, Genzyme, France) for 20 hours at 4 °C. Heterotopic autotransplantation was performed into the right iliac fossa onto the external iliac vessels with an end-to-side anastomosis and a nonstented uretero-ureteral anastomosis was performed. RESULTS Twenty-five renal allotransplantations were performed over a 5-month time period. Mean operating time progressively decreased and stabilized after 15 procedures (mean ± SD: 78.2 ± 19 minutes and 187.4 ± 18 minutes for left nephrectomy and transplantation, respectively) as morbidity decreased concomitantly. Suturing times for end-to-side anastomosis of the renal artery and vein onto the external iliac artery and vein were 21.9 ± 7 minutes and 34 ± 8 minutes (mean ± SD), respectively. Ten pigs died before the end of the experiment. CONCLUSIONS We have developed and validated the first nonrodent animal model of heterotopic renal autotransplantation relevant to the human anatomy and physiology. The procedure was easy to learn and safe. This model could be used to teach junior surgeons renal transplantation techniques and could also be used as a model to study ischemia-reperfusion injury in renal transplantation.

Abstract
Abnormal sexual development causes unconformity between gender identity and gender role. In countries with low socio-economic level, the optimal management is difficult. The aim of this study was to evaluate the frequency, the genital anatomy appearance, the diagnostic and the surgical management of disorders of sex development (DSD) discovered during the adolescence. Between January 2005 and November 2006 (23 months), five patients with abnormal sexual development were identified in Point G Hospital. First-line testing included biology measurement and imaging. A surgical management was systematically offered. Median age was 19.5±11.8 years (6-31). All patients were initially assigned male. Sexual dimorphic with genital ambiguity was the first reason of consultation (three children to five). One patient had male breast development and one had pelvic pain. All clinical evaluation suggested genital ambiguity. The diagnostic was female pseudohermaphrodism in three cases, true hermaphrodism in one case and hypogonadism for one patient. A masculinizing genital surgery was performed in three cases. The other patients refused the treatment or were out of sight. Intersex disorders are relatively rare in Mali with a prevalence of 2.30‰ in our hospital. This study highlighted the lack of financial means and local resources for optimal clinical management of individuals with DSD.

Abstract
Measuring the age of molecular clouds and prestellar cores is a difficult task that has not yet been successfully accomplished although the information is of paramount importance to help in understanding and discriminating between different formation scenarios. Most chemical clocks suffer from unknown initial conditions and are therefore difficult to use. We propose a new approach based on a subset of deuterium chemistry that takes place in the gas phase and for which initial conditions are relatively well known. It relies primarily on the conversion of H(3)(+) into H(2)D(+) to initiate deuterium enrichment of the molecular gas. This conversion is controlled by the ortho/para ratio of H(2) that is thought to be produced with the statistical ratio of 3 and subsequently slowly decays to an almost pure para-H(2) phase. This slow decay takes approximately 1 Myr and allows us to set an upper limit on the age of molecular clouds. The deuterium enrichment of the core takes longer to reach equilibrium and allows us to estimate the time necessary to form a dense prestellar core, i.e. the last step before the collapse of the core into a protostar. We find that the observed abundance and distribution of DCO(+) and N(2)D(+) argue against quasi-static core formation and favour dynamical formation on time scales of less than 1 Myr. Another consequence is that ortho-H(2) remains comparable to para-H(2) in abundance outside the dense cores.

Abstract
Paratesticular rhabdomyosarcoma is a rare and highly aggressive embryonal tumor in infancy and childhood. The tumor is intrascrotal, localized in the spermatic cord, the epididymis, or in the tunica vaginalis. Rhabdomyosarcoma represents 10% of testicular tumors of infancy. On physical examination, a painless scrotal tumefaction is observed. A surgical and pathological classification is used to group patients according to the extent of residual tumor after the initial surgical procedure: Intergroup Rhabdomyosarcoma Study classification (IRS). Multimodality therapy involving surgery, chemotherapy, and radiotherapy is necessary. Depending on the extent of disease and the staging group, the approach of treatment is different. The most important factors affecting treatment outcome are the stage, the pathological subtype of the tumor, and the age of the patient. Younger patients (<10 years) with a local tumor and with embryonal pathology have an excellent prognosis. We report the case of a 6-year-old boy admitted for a specialist consultation because of the recent appearance of a tumor in the right scrotum. On physical examination, a painless, solid, right scrotal mass was noted and the diagnosis of paratesticular rhabdomyosarcoma was made. This diagnosis can be suspected on physical and on ultrasound examinations, but only a pathological examination will confirm it. The authors discuss the therapeutic issues raised by this lesion and report one case of paratesticular rhabdomyosarcoma.

Abstract
The use of uncontrolled deceased donors after cardiac arrest (uDDCA) has been developed in France to compensate for organ shortage. The quality of these kidneys remains unclear. We analyzed kidney graft function and histology from 27 uDDCA and compared them with kidneys from 30 extended criteria donors (ECD) and from 24 simultaneous pancreas kidney (SPK) donors as a control group of optimal deceased donors. Kidneys from ECD and SPK donors were preserved by static cold storage while kidneys from uDDCA were preserved by pulsatile perfusion. The uDDCA graft function at 3 years posttransplantation (estimated with MDRD and measured with inulin clearance) did not differ from that of the ECD group (eGFR 44.1 vs. 37.4 mL/min/1.73 m(2) , p = 0.13; mGFR 44.6 vs. 36.1 mL/min/1.73 m(2) , p = 0.07 in the uDDCA and ECD groups, respectively). The histological assessment of 3-month and 1-year protocol biopsies did not show differences for interstitial lesions between the uDDCA and ECD grafts (IF score at M3 was 30 vs. 28% and at M12 36 vs. 33%, p = NS). In conclusion, the results at 3 years with carefully selected and machine-perfused uDDCA kidneys have been comparable to ECD kidneys and encourage continuation of this program and development of similar programs.

Abstract
AIMS To analyze the results of treatment of major renal injuries according imaging data in order to determine their function after follow-up. PATIENTS AND METHODS This is a retrospective study of 22 cases of fracture of the kidney (grade V) in two pediatric surgical services that were reviewed over a period of 16 years. After initial conservative treatment in 19 patients (86.5%), a scan and/or Uro-MRI were realized in all patients in monitoring evolving. Three children with vascular injury were treated by interventional radiology. The morphology and functional evolution of the injured kidney were determined. RESULTS A DMSA scan investigation was performed in 21 patients (95.5%) associated with Uro-MRI in two cases; one patient was only explored with Uro-MRI. A complete restitution of the renal parenchyma was confirmed in 10 children (45.5%), we noted an atrophy of the upper pole in 30%, a lower pole atrophy in 4.5%, two complete renal atrophy in 9%. An urinoma was present in six patients (27%) that required drainage in five cases and declined during the surveillance in one case. Normal function of the injured kidney was noticed in half of grade V (11 of 22 patients) with a mean follow-up of 19 months. None of our patients did present hypertension. CONCLUSION Non-operative conservative treatment in severe renal trauma was efficient, morphological and functional sequelae were present in 50% on scintigraphy and/or Uro-MRI.

Abstract
We report extensive, accurate fully quantum, time-independent calculations of cross sections at low collision energies, and rate coefficients at low temperatures for the H⁺ + H₂(v = 0, j) → H⁺ + H₂(v = 0, j') reaction. Different transitions are considered, especially the ortho-para conversion (j = 1 → j' = 0) which is of key importance in astrophysics. This conversion process appears to be very efficient and dominant at low temperature, with a rate coefficient of 4.15 × 10⁻¹⁰ cm³ molecule⁻¹ s⁻¹ at 10 K. The quantum mechanical results are also compared with statistical quantum predictions and the reaction is found to be statistical in the low temperature regime (T < 100 K).

Abstract
We report a case of a renal mass in a 4-month boy, which occured during the assessment of a pelvi-calyceal dilatation diagnosed at 23 weeks of gestational age. There was no history of urinary infection, fever or weight loss. Physical examination revealed a mass of the left flank with significant flank tenderness. Laboratory test showed a biological inflammatory syndrome and urine culture was negative. Investigations including ultrasound and computed tomography scan were suggestive of diffuse xanthogranulomatous pyelonephritis with a non-functioning left kidney. Left total nephrectomy was performed through a lumbar incision with an extraperitoneal approach. The kidney was enlarged with a dilated pelvis containing pus upstream of a proximal ureteral atretic segment. Pathological examination of the kidney confirmed the diagnosis of diffuse xanthogranulomatous pyelonephritis. The boy remains well at 1 year follow-up. Xanthogranulomatous pyelonephritis is very rare in infants. It is an uncommon severe progressive renal infection resulting in destruction of renal parenchyma, histologically replaced by xanthomatous cells and granulomatous reaction. Pathogenesis of xanthogranulomatous pyelonephritis remains unclear. But it is well known that urinary tract obstruction and renal lithiasis are determining factors. It can occur in variant clinical forms but its symptoms remain non-specific. Curative treatment consists in nephrectomy and definitive diagnosis is made on histological examination of the kidney. This diagnosis should be discussed when a renal mass occurs in a context of malformative uropathy and xanthogranulomatous pyelonephritis have to be included in the differential diagnosis of renal mass in infants and children.
