Abstract
BACKGROUND Metanephric adenoma is a rare benign renal tumor of the kidney, uncommonly observed in children. It is often misdiagnosed preoperatively as a malignant neoplasm, leading to an unnecessary nephrectomy. The challenge is to make the right diagnosis preoperatively and therefore manage it with conservative surgery. We report a case of a child with metanephric adenoma who underwent nephron-sparing surgery. CASE PRESENTATION A renal tumor was discovered fortuitously in an 18-month-old Caucasian girl with several congenital malformations. Investigations showed a 28 × 27 × 27 mm left renal mass centrally located, well defined, nonvascularized, with no calcifications and which compressed the adjacent renal tissue. Furthermore, there were no signs of metastasis. The decision of a multidisciplinary meeting was to perform a computed tomography (CT)-scan-guided biopsy. Histologic examination concluded it was a metanephric adenoma. We performed a left open partial nephrectomy via a flank retroperitoneal incision. The final histopathological examination confirmed the diagnosis. The postoperative course was uneventful. CONCLUSION Preoperative diagnosis of metanephric adenoma is challenging. Because of the high probability of unnecessary radical nephrectomy, preoperative biopsy can be safe and determining to guide a more conservative approach so nephron-sparing surgery can be performed.

Abstract
PURPOSE This in vitro study evaluated technical outcomes of monolithic zirconia implant-supported fixed dental prostheses (iFDPs) supported by different designs of titanium base abutments after aging and static load testing. MATERIALS AND METHODS Sixty three-unit monolithic zirconia (yttrium oxide partially stabilized tetragonal zirconia polycrystals; Y-TZP)iFDPs were produced and divided into four groups: group A-conical titanium base abutments for the prosthesis; group B-cylindrical titanium base abutments for the crown; group C-conical titanium base abutment for the prosthesis and cylindrical titanium base abutment for the crown; group D-cylindrical titanium base abutments for the prosthesis. The samples were subjected to an aging protocol and to continuous static loading until failure and analyzed visually and with specific software. The technical outcomes comprised the occurrence of debonding, screw loosening, deformation and fracture, abutment deformation and fracture, implant deformation and fracture, zirconia chipping and fracture, and bending moments. The Pearson chi-squared test (χ2) and Fischer exact test were used to compare the outcomes. The Kolmogorov-Smirnov test was used to evaluate data distribution of the bending moments. Analysis of variance (ANOVA) was used for the analysis of parametric data distribution, and the Kruskal-Wallis test was used for nonparametric data distribution. RESULTS After aging, a higher percentage of debonding (P = .042) and micromovement (P = .034) was recorded in group C (P = .042). The conical titanium base abutments had a higher debonding (P = .049) and a higher macromovement rate (P = .05). The static load test showed higher bending moments in group D (P = .001) and lower bending moments in group A (P = .001). Debonding was highest in group C (P = .001) and lowest in group A (P = .002). Complete loss of retention rate was highest in group C (P = .001). The conical titanium base abutment had the highest debonding rate (P = .001) and complete loss of retention (P = .001). The micromovement rate was the highest for cylindrical titanium base abutments for the crown (P = .001). The lowest screw loosening, zirconia chipping, and fracture rate (P = .001) and the highest screw deformation (P = .004) were recorded in group A. The screw deformation rate was lowest in the cylindrical titanium base abutments for the crown (P = .008). CONCLUSION The mixed titanium base abutment design comprising one conical and one cylindrical abutment in Y-TZP iFDPs led to the highest debonding rate. The cylindrical titanium base abutment for the prosthesis provided a lower percentage of debonding and the highest load resistance.

Abstract
Objectives: The aim of this study was to evaluate the effect of different enamel surface treatments on the micro-shear bond strength. Materials and methods: Sixty-four approximal surfaces from freshly extracted molars were randomly assigned to eight groups, according to combinations of the following enamel surface treatments: ground or unground, 37.5% phosphoric acid etching time of 15 or 30 s, and with or without primer application. The same bonding agent (Optibond FL™ Adhesive, Kerr) was then used for all groups, and a 1.8 mm diameter resin composite (Harmonize™, Kerr) cylinder was built up on the bonded surface. Samples underwent a shear force test at a crosshead speed of 1 mm/min until failure. Bond strength was calculated, and failure modes were inspected under an optical microscope. Results: Bond-strength values ranged from 8.2 MPa for 15 s etched unground enamel with primer application to 19.6 MPa for 30 s etched ground enamel without primer application. ANOVA and Fisher’s LSD post hoc tests revealed significant differences between the groups. Conclusions: Etching time and grinding have a statistically significant effect on the micro-shear bond strength of a three-step etch-and-rinse adhesive system on enamel. Primer application does not seem to be beneficial for enamel adhesion.

Abstract
INTRODUCTION Reduced tongue pressure may render eating and swallowing difficult. The purpose of this study was to investigate whether the tongue training device can also be used as a diagnostic device and whether its sensitivity and specificity are equal to the numerical tongue pressure measuring device. MATERIAL AND METHODS The target group is patients aged 70 years and over who are hospitalised for rehabilitation. Tongue pressure was measured by both, a tongue pressure measuring instrument and a tongue training tool. The diagnosis of the reduced tongue pressure was made with the tongue pressure measuring instrument and set the verified with the novel tongue training tool. RESULTS Sixty-two participants were included in the study. Forty-five were classified by the tongue pressure measuring device and 53 by the tongue training device as 'low tongue pressure'. Spearman correlation confirmed a positive correlation between the tongue pressure measuring device and the tongue training device rs = 0.800, p = 0.01 level (2-tailed). The tongue training device test identified sensitivity was 100%, and its specificity was 52.9%. The AUC of the ROC curve is 0.901. CONCLUSION The tongue training device seems a simple, safe and readily available alternative to the tongue pressure measuring device for the diagnosis of low tongue pressure, with an excellent sensitivity and very good specificity.

Abstract
OBJECTIVES This study evaluated the biocompatibility, mechanical properties, and surface roughness of CAD-CAM milled and rapidly-prototyped/3D-printed resins used for manufacturing complete dentures. METHODS Six groups of resin specimens were prepared, milled-base (MB), milled-tooth shade (MT), printed-tooth shade (PT), printed-base with manufacturer-recommended 3D-printer (PB1), printed-base with third-party 3D-printer (PB2), printed-base in a vertical orientation (PB2V). Human epithelial (A-431) and gingival (HGF-1) cells were cultured and tested for biocompatibility using Resazurin assays. Three-point bending and nanoindentation tests measured the mechanical properties of the resin groups. Surface roughness was evaluated using a high-resolution laser profilometer. ANOVA and post-hoc tests were used for statistical analyses (α = 0.05). RESULTS There were no significant differences in biocompatibility between any of the investigated groups. MB revealed a higher ultimate strength (p = 0.008), elastic modulus (p = 0.002), and toughness (p = 0.014) than PB1. MT had significantly higher elastic modulus than PT (p < 0.001). Rapidly-prototyped resin samples with a manufacturer-recommended 3D-printer (PB1) demonstrated higher ultimate strength (p = 0.008), elastic modulus (p < 0.001), hardness (p < 0.001) and a reduced surface roughness (p < 0.05) when compared with rapidly-prototyped groups using a third-party 3D-printer (PB2). Rapidly-prototyped samples manufactured with a vertical printing orientation (PB2V) revealed a significantly lower elastic modulus than samples groups manufactured using horizontal printing orientation (PB2) (p = 0.011). CONCLUSIONS Within the limits of this present study, CAD-CAM milled and rapidly-prototyped complete denture resins performed similarly in terms of biocompatibility and surface roughness. However, the milled denture resins were superior to the rapidly-prototyped denture resins with regard to their mechanical properties. Printing orientation and type of 3D-printer can affect the resin strength and surface roughness.

Abstract
Deproteinized bovine bone mineral particles embedded in collagen (DBBM-C) are widely used for bone regenerations with excellent, albeit sometimes variable clinical outcomes. Clinicians usually prepare DBBM-C by mixing with blood. Replacing blood by saline represents an alternative. We investigated if saline treatment could improve DBBM-C i. handling in vitro and ii. biological performances in a rabbit calvarial model. In vitro, DBBM-C blocks soaked in saline or blood were submitted to compression tests. In vivo, four poly ether ether ketone (PEEK)cylinders were placed on 16 rabbit skulls, filled with DBBM-C soaked in blood or saline for 2-4-8-12 weeks before histomorphometry. DBBM-C blocks were fully hydrated after 30 s in saline when 120 s in blood could not hydrate blocks core. Stiffness gradually decreased 2.5-fold after blood soaking whereas a six-fold decrease was measured after 30 s in saline. In vivo, saline treatment allowed 50% more bone regeneration during the first month when compared to blood soaking. This difference was then no longer visible. New bone morphology and maturity were equivalent in both conditions. DBBM-C saline-soaking facilitated its handling and accelerated bone regeneration of highly qualitative tissues when compared to blood treatment. Saline pretreatment thus may increase the clinical predictability of bone augmentation procedures.

Abstract
Objectives
This study tested the hypothesis that modifying the sequence of sodium hypochlorite (NaOCl)/ethylene diamine tetra-acetic acid (EDTA) irrigation during root canal shaping would improve apical cleanliness in moderately curved canals.
Materials and Methods
Forty-five root canals were prepared using Protaper Gold with three irrigation protocols. Standard irrigation (SI) used 0.5 mL 3% NaOCl between each instrument, followed by 5 mL 17% EDTA manually agitated for 30 seconds. Reverse irrigation (RI) used 0.5 mL of 17% EDTA between each instrument, then 5 mL of 3% NaOCl, manually agitated for 30 seconds. Reverse irrigation plus (RI+) was similar to RI, except NaOCl (5 mL), used as a final rinse, was allowed to interact for 3 minutes with dentin before manual agitation (30 seconds).
Root canal cleanliness was evaluated under the scanning electron microscope (SEM) (Hulsmann score); the chemical composition of dentin after irrigation was analyzed by energy dispersive X-ray (EDX). Statistical Analysis
Results were compared using Kruskal–Wallis ANOVA by ranks and Wilcoxon matched paired posthoc tests. A Chi-square test assessed whether the best cleanliness would demonstrate a significant association with one irrigation protocol; odds ratio calculation was performed using score “1” versus score “2 or more” (2+) (
p
< 0.05).
Results
In the apical region, cleanliness was better in RI+ than SI and both significantly better than RI. Odd ratios indicate that the cleanliness in RI+ was significantly better than RI and SI groups (
p
< 0.000 and 0.003, respectively). Independently of the irrigation protocol, EDX analyses showed no chemical alteration of root dentin.
Conclusions
Using 17% EDTA during shaping, followed by 3% NaOCl rinse for 3 minutes, improved apical cleanliness without inducing erosion of dentin.

Abstract
The basic principle of the rabbit calvarial model is to grow new bone tissue vertically on top of the cortical part of the skull. This model allows assessment of bone substitution materials for oral and craniofacial bone regeneration in terms of bone growth and neovascularization support. Once animals are anesthetized and ventilated (endotracheal intubation), four cylinders made of polyether ether ketone (PEEK) are screwed onto the skull, on both sides of the median and coronal sutures. Five intramedullary holes are drilled within the bone area delimited by each cylinder, allowing influx of bone marrow cells. The material samples are placed into the cylinders which are then closed. Finally, the surgical site is sutured, and animals are awaken. Bone growth may be assessed on live animals by using microtomography. Once animals are euthanized, bone growth and neovascularization may be evaluated by using microtomography, immune-histology and immunofluorescence. As the evaluation of a material requires maximum standardization and calibration, the calvarial model appears ideal. Access is very easy, calibration and standardization are facilitated by the use of defined cylinders and four samples may be assessed simultaneously. Furthermore, live tomography may be used and ultimately a large decrease in animals to be euthanized may be anticipated.

Abstract
Cardiac subsarcolemmal mitochondria (SSM) and interfibrillar mitochondria (IFM) subpopulations display distinct biochemical, morphological, and functional characteristics. Moreover, they appear to be differently influenced during cardiac pathologies or toxic injuries. Although mitochondrial reactive oxygen species seem to play a critical role in cardiac function and diseases, limited information exists about the superoxide production characteristics of these mitochondrial subpopulations. In this work, using direct measurement of superoxide by electron paramagnetic resonance, we showed that differences in superoxide production profiles were present between cardiac IFM and SSM, in terms of intensity and major sites of superoxide generation. In SSM incubated with glutamate plus malate as substrates, the total observed superoxide levels were significantly higher than those observed with IFM, with an important contribution of the NADH-oxidizing site of complex I (site If) and the quinol-oxidizing site of complex III (site IIIQ0). In both IFM and SSM, succinate leads to similar rates of total superoxide levels with a substantial role for contribution of reverse electron transfer. Finally, using two spin probes with different membrane permeabilities, our data on complex III showed direct intra- and extra-mitochondrial superoxide release whereas complex I- and II-dependent superoxide were exclusively released inside the mitochondria, confirming previous studies. Feasibility of this approach to measure intra- and extra-mitochondrial superoxide levels and to characterize distinct superoxide production profiles of cardiac IFM and SSM has been demonstrated.

Abstract
UNLABELLED Gastric volvulus is an abnormal rotation of all or a part of the stomach around one of its axes. It is a rare cause of intestinal obstruction in children. This anomaly can be primary, due to abnormalities of the gastric ligaments, or secondary to other congenital malformations. We report on the cases of five children treated between January 1994 and December 2011, four boys and one girl, with a medium age of 7 months. Diagnosis was based on clinical features, particularly in the upper gastrointestinal Rx contrast study, which confirmed the diagnosis. Four out of the five children underwent laparoscopic surgery with fixation of the stomach. A diaphragmatic hernia was associated in one case. Antireflux surgery was performed in three cases, and a diaphragmatic defect was closed in one case. The follow-up was uneventful after a medium period of 7 years. CONCLUSION good knowledge of this anomaly is the guarantee of early diagnosis and optimum treatment to ameliorate the prognosis.

Abstract
Teratomas are unusual tumors derived from all 3 germs cells layers: endoderm, mesoderm, and ectoderm, with varying proportions. The cervical area is exceptionally affected. We report 4 cases of cervical teratoma. The clinically and radiologically suggested diagnosis was confirmed by histology. We describe herein the main clinical, radiological, and histological aspects and outcomes of this disease. Despite its most often benign histologic nature, cervical teratoma may threaten newborn infants' life due to airway compression. A multidisciplinary approach to the disease starting at delivery is required to improve the prognosis.

Abstract
UNLABELLED Esophageal stricture is a rare but often severe complication of recessive dystrophic epidermolysis bullosa in children. The purpose of the study was to review this digestive complication with emphasis on diagnostic modalities and therapeutic management. PATIENTS AND METHODS This was a retrospective study of two pediatric cases of esophageal stenosis that occurred during generalized recessive dystrophic epidermolysis bullosa of the Hallopeau-Siemens type. RESULTS The 2 patients were aged 8 years 8 months and 11 years 5 months, respectively. Dysphagia was of early onset, before the age of 10 years in both cases. Esophageal opacification led to the diagnosis of esophageal stenosis located in the upper 1/3 of the esophagus in 1 case and at the junction between the middle and the lower 1/3 of the esophagus in the other case. None of the 2 patients received medical treatment, and pneumatic dilation was the treatment method that was advocated. Esophageal endoscopy showed the stenosis and helped guide the positioning of the balloon catheter. These patients underwent 2 and 3 sessions of dilation, respectively, at intervals of 2 months and 1 year. Balloon dilation has allowed the patients to have a more comfortable life with decreased dysphagia and a substantial improvement in nutritional status. However, this improvement was transient (1 patient had symptomatic recurrence of stenosis after 3 years), which shows that monitoring of the patients and the resumption of dilatation sessions may be necessary. CONCLUSION Esophageal strictures in dystrophic epidermolysis bullosa of the Hallopeau-Simens type are severe and difficult to support. Pneumatic dilatation is the treatment of choice for the fragile esophagus. It gives satisfactory results and can be repeated without significant risk.

Abstract
OBJECTIVES Titanium is widely used in contemporary endosseous implantology and there is considerable thrust to further promote osseointegration by implant surface modifications. The aim of this study was to evaluate the effect of a titanium-nitride-oxide (TiNOx) coating on commercially pure microroughened titanium by assessing the proliferation and differentiation of human primary osteoblasts. MATERIALS AND METHODS Cell proliferation, gene expression, alkaline phosphatase activity, osteoprotegerin and osteocalcin secretion were analyzed for a time course of 3 weeks, with or without additional stimulation by 1.25(OH)(2) vitamin D(3) 100 nM. RESULTS A 1.5-fold increase in the proliferation rate of cells grown on TiNOx-coated titanium as compared with uncoated surfaces was observed. SEM views indicated that the cells' normal morphology with their numerous extensions was maintained. The differentiation process on the TiNOx surface was only affected to a minor degree and translated into a slight delay in osteoblast maturation when compared to uncoated titanium. CONCLUSION Pending confirmation of these results in vivo, TiNOx coatings could potentially accelerate and enhance osseointegration.

Abstract
The object of the study was to fill and coat the microcavities of a drug eluting stent using a batch dipping process. 316L coronary stents, which were coated with a 0.25 μm layer of TiNOx were used as substrates. The stents’ surface was dimpled with 0.21 μl microcavities separated by distances of 17–28 μm depending on location. The experiment consisted of (1) optimizing the procedures to fill the microcavities with a solution of therapeutic agent and (2) covering the filled microcavities with a protective “lid” that shielded the solution during stent insertion in the arteries and then controlled its release into the surrounding tissue. The filling solution was a water-propanol mix containing 20% L-arginine. The coating solution was comprised of poly-ethylene-glycol (PEG-8000) and dexamethasone. The filling quality was investigated after altering the following variables: plasma surface activation (type of gas, pressure, power, and duration), water-propanol percentage ratio of the filling solution, lifting speed from the bath, and effect of ultrasonic vibration (monofrequency versus multifrequency). The surface coating was evaluated by altering the PEG-8000-dexamethasone percentage ratio and recording the effects on coating thickness and structure, on elution rate, and on wear resistance. The optimized process is presented in detail.

Abstract
The study was designed to determine comparatively the prognostic value of immunoblotting and ELISA in the serological follow-up of young cystic echinococcosis (CE) patients exhibiting either a cured or a progredient (non-cured) course of disease after treatment. A total of 54 patients (mean age 9 years, range from 3 to 15 years) with surgically, radiologically and/or histologically proven CE were studied for a period up to 60 months after surgery. Additionally, some of the patients underwent chemotherapy. Based on the clinical course and outcome, as well as on imaging findings, patients were clustered into 2 groups of either cured (CCE), or non-cured (NCCE) CE patients. ELISA showed a high rate of seropositivity 4 to 5 years post-surgery for both CCE (57.1%) and NCCE (100%) patients, the difference found between the two groups was statistically not significant. Immunoblotting based upon recognition of AgB subcomponents (8 and 16 kDa bands) showed a decrease of respective antibody reactivities after 4 years post-surgery. Only sera from 14.3% of CCE patients recognized the subcomponents of AgB after 4 years, while none (0%) of these sera was still reactive at 5 years post-surgery. At variance, immunoblotting remained positive for AgB subcomponents in 100% of the NCCE cases as tested between 4 and 5 years after surgical treatment. Immunoblotting therefore proved to be a useful approach for monitoring post-surgical follow-ups of human CCE and NCCE in young patients when based upon the recognition of AgB subcomponents.

Abstract
BACKGROUND Spontaneous perforation of the bile duct (SPBD) is a rare disease in infancy. The pathogenesis, diagnostic modalities and treatment options for this condition are reviewed and discussed. METHODS The authors report 2 new observations of SPBD in 2 male newborns aged respectively 27 and 21 days. RESULTS The 2 newborns presented with cholestatic jaundice. Abdominal sonography showed an extrahepatic mass. Exploratory laparotomy revealed that the perforation was located in the cystic duct in the first case and in the common bile duct (CBD) in the second. The site of perforation was repaired and both patients underwent simple external biliary drainage. The postoperative course was uneventful for both patients with follow-up ranging from 2 to 4 years. CONCLUSIONS SPBD is a rare, but important cause of surgical jaundice in infants. The pathogenesis of SPBD is unknown and multifactorial and diagnosis is often problematic. Surgical management is always required and a conservative approach is usually recommended. The prognosis is good with early surgical management.

Abstract
Cystic echinococcosis, which commonly starts during childhood or adolescence, is a serious problem of public health in Tunisia. For 121 children (161 cysts), the localization and fertility of cysts as well as viability of their protoscoleces were determined. Results indicated that the lung was the primary localization of cyst (59%) followed by the liver (35%). Children's infection is more frequent in male than in female (sex ratio 1.96) and the greatest number of cases is observed in the 4-9 year age groups (94 cases). The fertility of the cyst was independent of its site or its size and no incidence of age of children was detected. Nevertheless, the fertility rate is higher in females than in males for the liver localization.

Abstract
OBJECTIVE Intussusception owing to pathologic lead points is a challenging condition for pediatric surgeons. The aim of this study was to review the particularities of clinical presentation, the place of morphologic investigation in depicting the presence of an organic lesion and the management of secondary intussusception. PATIENTS AND METHODS The authors report a series of 27 patients treated from 1986 to 2004, for secondary intussusception. RESULTS Nineteen boys and 8 girls, aged from 45 days to 11 years (mean age: 40 months) presented with secondary intussusception: Meckel's diverticulum (13 cases); lymphoma (8 cases); intestinal duplication (3 cases); heterotopic pancreas (2 cases); intestinal polyp (1 case). All patients were operated upon after failure of hydrostatic reduction. An intestinal resection with an end to end anastomosis was done for 26 patients. The biopsy of a large abdominal mass after an easy reduction of the intussusception was performed in 1 case. Chemotherapy was started at the sixth postoperative day for the 8 children having lymphoma. Two of them died during therapy. For the 25 others, the postoperative course was uneventful with a mean follow-up of 4 years. COMMENTARY The improvement of the management and the prognosis of secondary intussusception requires an early diagnosis. Morphologic examination must not be limited to the diagnostic of intussusception but must aim at searching a lead point. The reduction of this particular form is based exclusively on surgery.

Abstract
Congenital esophageal stenosis due to tracheobronchial remnants is a rare malformation whose diagnosis may be difficult. It is characterised by the abnormal presence of congenital tissue of tracheal origin in the esophageal wall, which is responsible for the narrowing of the esophagus. We report 2 cases whose treatment was surgical after failure of esophageal dilations. The presence of tracheal-bronchial tissue was confirmed by histological examination of the operative piece. Outcome was favourable and the final result was excellent. Recently, endoscopic ultrasonography has been proved useful in the diagnosis of congenital esophageal stenosis due to tracheobronchial remnants by showing the presence of cartilage, which explains the failure of dilation. The high rate of perforation in these cases is due to brutal fragmentation of the cartilaginous rings. Surgical resection of esophageal stenosis with the tracheobronchial tissue appears the only treatment susceptible to completely suppress the stenosis and its consequences.

Abstract
Ovine and dromedary Echinococcus granulosus isolates from Tunisia were identified as G1 and G6 strains based on polymorphism of the mitochondrial cytochrome C oxydase CO1. Single strand conformation polymorphism (SSCP) was used in order to examine the genetic variation within and between Tunisian G1 and G6 strains and to estimate the extent of selfing. The dromedary isolates are genetically distinct from sheep isolates (high value of genetic variation between populations: Fst= 0.46). No significant deficiency in heterozygotes was found in sheep isolates, whereas heterozygote deficiency (suggesting selfing) was found in a limited number of camel isolates.

Abstract
OBJECTIVES To describe a new method of treatment of the fourth branchial pouch sinuses by laser endoscopic coagulation of the fistula. MATERIAL AND METHODS Retrospective study of two children aged 3 and 12 years with fourth branchial pouch sinuses. Both children presented recurrent cervical abscesses. The diagnosis was established on results of ultrasound, barium study, CT scan and pharyngoscopy. After recovering from infection, the definitive treatment was a laser diode cauterization of the fistulous route and its pharyngeal opening. RESULTS Outcome was rapidly favorable in both children without complications or recurrence. DISCUSSION These two cases and other reports in the literature confirm the role of endoscopic management for the treatment of the fourth branchial pouch sinus. Laser treatment is especially useful because of its convenience, its harmlessness and its reliability. CONCLUSION Fourth branchial pouch sinuses are rare. Surgery, which can be difficult and not without risks, is the generally accepted treatment. This new laser method combines ease of treatment and efficacy.

Abstract
Three hundred and seventy-two cysts coming from 50 humans, 166 cattle, 153 sheep and 3 camels were collected in order to establish some epidemiological molecular information in Tunisia for the first time. The analysis by PCR-RFLP of ITS1 sequence showed that all the human, ovine and bovine cysts were due to the common sheep strain of Echinococcus granulosus. The sequencing of the CO1 gene of 37 isolates confirm the G1 genotype of this strain. For seven of these isolates, we found the mutation C56T which is present in the three principal intermediate hosts: human (three cysts), cattle (three cysts) and sheep (one cyst). With regard to the G1 genotype, we identified three other point mutations. The camel strain G6 is uniquely found in the three camels isolates and not in the other intermediate hosts analysed. The fertility of the bovine cyst represents 48% that means that this host is involved in a bovine-dog cycle and consequently represents a reservoir of sheep strain in Tunisia. Our results confirm the importance of the prophylaxis measures in order to disrupt the cycle of transmission sheep-dog in Tunisia. Nevertheless, the supervision of bovine infection should be reinforced because this intermediate host may constitute an important link with the human contamination.

Abstract
Allozyme variation at seven polymorphic loci (GPI, EST, MDH, MPI, DIA, PEP, PGM) was studied to examine genetic variation within and between sheep, cattle and human populations of Echinococcus granulosus in Tunisia. A high degree of genetic similarity was shown between the cysts of the three host origins. Nevertheless, whereas, the ovine and human samples were highly similar, the cattle samples were slightly different genetically. We conclude that humans are mostly infected by parasites originating from sheep liver. The intense deficiency in heterozygotes was partly artefactual (Wahlund effect) and partly due to self-fertilisation.

Abstract
UNLABELLED The malignant tumours of the kidney are not very frequent during the first year of life and pose diagnostic and therapeutic problems. The aim of this work is to make an analysis of the epidemiologic, clinical and anatomo-pathological characteristics of these tumours during the first year of life and a development on the therapeutic methods and their results. MATERIAL AND METHODS [corrected] This is a retrospective study of 8 observations of malignant tumours of the kidney whose first symptomatology appeared during the first year of life. RESULTS The malignant tumours of the kidney observed before the one year age constituted 18% of the tumours of the kidney in the child. A female prevalence was noted with a sex-ratio of 0.6. The assessment of extension found cutaneous (one case), ganglionic (one case) and pulmonary (two cases) metastases. First chemotherapy was prescribed to five patients. The surgery consisted on a widened nephrectomy in seven cases and a tumorectomy for an infant presenting a nephroblastomatosis. The tumour corresponded to a nephroblastoma in seven cases and a rhabdoide tumour in the last case. Mortality was high (50%) caused by the toxicity of chemotherapy in three cases and an advanced stage of cancer in one case. CONCLUSION Renal tumoral pathology occurring in infants less than one year of age poses true etiologic and therapeutic problems. The high frequency of the nephroblastoma and the absence of benign tumour in our series encourage us to evocate more often the malignant renal tumours and to practice per cutaneous biopsies in case of diagnostic doubt.

Abstract
Urethral duplication is a rare anomaly, affecting mainly boys. The clinical presentation varies because of the different anatomical patterns of this abnormality. We report 4 cases of urethral duplication in children. An epispadiac duplication was present in 1 case, hypospadiac duplication in 1 case, Y-duplication in 1 case and a congenital prepubic sinus in the last case. The pre-operative probe was based on urethrocystography and fistulography. The surgical management included excision of the duplicated urethra in 3 cases. Transurethral incision of the intra-urethral septum was performed in the case of hypospadiac duplication. The characteristics of male urethral duplication are reviewed.

Abstract
The purpose of this study was to evaluate the efficiency and safety of oesophageal balloon dilatation in strictures secondary to surgical treatment of oesophageal atresia in 25 children. Patients comprised 15 males and 10 females, aged 1-36 months. Median age was 4 months (interquartile range (IQR)=19). The strictures were more than 50% of oesophageal lumen and the delay from surgical treatment to balloon dilatation varied from 1 month to 36 months. Associated gastroesophageal reflux was noted in 15 patients. All procedures were performed under sedation using fluoroscopic guidance. Balloons of increasing diameter, 4-20 mm were used. Water soluble contrast swallow was performed after each dilatation session. A total of 115 balloon dilatation sessions were performed with a range of 1-14 procedures per patient (median 4 dilatations, IQR=4.5). Dilatation relieved the stricture in all patients over a follow-up period varying from 4 months to 33 months. The best results were noted in children under 6 months, who needed two or few dilatation sessions, with relative risk (RR) of 0.52 and 95% confidence interval of 0.29-0.92. The presence of associated gastroesophageal reflux indicated a high risk (RR of 12, p<0.001) for undergoing more than two balloon dilatation sessions. The only serious complications observed were two cases of oesophageal perforation, which were treated conservatively. Fluoroscopically guided balloon dilatation is a safe and effective treatment in the management of strictures secondary to surgical repair of oesophageal atresia, especially when started early (within 6 months of surgery) and not associated with gastroesophageal reflux.
