Abstract
BACKGROUND Urothelial carcinoma, a prevalent and aggressive urological malignancy, necessitates early detection for improved prognosis. Urine cytology serves as a cost-effective screening tool, but inconsistencies in reporting due to the lack of standardized criteria limit its efficacy. The Paris System for reporting urinary cytology (TPS) was introduced to address this issue, aiming to improve diagnostic accuracy. This retrospective study investigates the effectiveness of urine cytology in detecting high-grade urothelial carcinoma (HGUC) using TPS classification, specifically focusing on atypical urothelial cells (AUC) categorized as TPS-III and suspicious for high-grade urothelial carcinoma (SHGUC) categorized as TPS-IV. METHODS We reviewed 470 urine cytology samples collected over two years at a tertiary healthcare center in Bahrain. All samples were re-evaluated using TPS classification by two independent consultant cytopathologists blinded to the original cytology report. The analysis included only samples categorized as TPS-III or TPS-IV with corresponding histopathology reports from confirmatory biopsies performed within four months of urine collection. Biopsy results were categorized as either benign/low-grade urothelial carcinoma (non-HGUC) or malignant (HGUC). The positive predictive value (PPV) of urine cytology for HGUC detection was calculated for both TPS-III and TPS-IV categories. Statistical significance was assessed using Fisher's exact test. RESULTS Among the 470 urine cytology samples, 40 (8.5%) were classified as TPS-III or TPS-IV. Within this subset, 16 patients underwent confirmatory biopsies. Histopathological analysis revealed HGUC in 12 (75%) patients and non-HGUC (benign or low-grade) in 4 (25%) patients. The PPV of TPS-III for HGUC was 50%, while TPS-IV demonstrated a higher PPV of 90%. However, the difference between these values was not statistically significant (p = 0.25). This study explored the utility of TPS classification in urine cytology for HGUC detection. While SHGUC (TPS-IV) exhibited a numerically higher PPV compared to AUC (TPS-III), the lack of statistical significance necessitates further investigation. Our findings highlight the potential of TPS to improve the accuracy of urine cytology. TPS implementation has been shown to reduce the number of inconclusive "atypical" diagnoses, leading to more targeted investigations. CONCLUSION Our study suggests that SHGUC (TPS-IV) within TPS classification framework might hold promise as a more specific indicator for HGUC compared to AUC (TPS-III). However, further research with larger cohorts is necessary to definitively establish the clinical significance of this observation. This investigation paves the way for future studies exploring the potential of TPS, particularly the SHGUC category, as a reliable screening tool for HGUC, potentially leading to earlier diagnoses and improved patient outcomes.

Abstract
Newcastle disease virus (NDV) is one of the most serious contagions affecting domestic poultry and other avian species. It causes high morbidity and mortality, resulting in huge economic losses to the poultry industry worldwide. Despite vaccination, NDV outbreaks increase the need for alternative prevention and control means. In this study, we have screened fractions of Buthus occitanus tunetanus (Bot) scorpion venom and isolated the first scorpion peptide inhibiting the NDV multiplication. It showed a dose dependent effect on NDV growth in vitro, with an IC50 of 0.69 µM, and a low cytotoxicity on cultured Vero cells (CC50 > 55 µM). Furthermore, tests carried out in specific pathogen-free embryonated chicken eggs demonstrated that the isolated peptide has a protective effect on chicken embryos against NDV, and reduced by 73% the virus titer in allantoic fluid. The N-terminal sequence, as well as the number of cysteine residues of the isolated peptide, showed that it belongs to the scorpion venom Chlorotoxin-like peptides family, which led us to designate it "BotCl". Interestingly, at 10 µg/mL, BotCl showed an inhibiting effect three times higher than its analogue AaCtx, from Androctonus australis (Aa) scorpion venom, on NDV development. Altogether, our results highlight the chlorotoxin-like peptides as a new scorpion venom AMPs family.

Abstract
Introduction The relationship between epilepsy and depression has been recognized for a long time. In fact, the presence of depression could worsen the disease outcome. Objectives we aimed to study the prevalence of depression in patients with epilepsy and to assess the determinant factors of its genesis. Methods 54 patients with epilepsy, aged more than 18 years, attending the neurology department of Habib Bourguiba Hospital, Sfax, Tunisia, were enrolled for the study. All patients were administered Mini-International Neuropsychiatric Interview (MINI) for evalution of psychiatric comorbid disorders especially depression. Socio-demographic and clinical data were collected. Results A total of 54 patients were included, of whom 63% (n =34) were men. Mean duration of epilepsy was 20.13 years. The most frequent type of seizure was generalized 72.7%. Depression was present in 7.3 % of patients. Alcoholism (p=0.027) was significantly associated with occurrence of depression. Drug resistence (p = 0.03) and longer duration of epilepsy (p = 0.046) were significantly associated with occurrence of depression. No significant association was found between type of seizure, seizure frequency, medication compliance and depression. Depression wasn’t associated with anti-epileptic drug. We didn’t find any association between depression and other psychiatric comorbidities. Conclusions Depression wasn’t frequent in our study contrary to literature. The possible explanations are the reduced simple size and the sensitivity of the used tool to assess depression in epilepsy. Pursuant to literature, we found significant association between Alcoholism, drug resistance and long duration of epilepsy.

Abstract
Introduction Gayet Wernicke Encephalopathy (GWE) is a diagnostic and therapeutic neuropsychiatric emergency due to thiamin deficiency (vitamin B1). Objectives The purpose of our work is to recall some clinical situations suspecting GWE, along with radiological and evolutionary profile. Methods We conducted a retrospective study concerning patients who were hospitalized in the neurology department of Habib Bourguiba Hospital between 2013 and 2020 for management of GWE. Results The median age of 7 patients was 39.57 years with sex ratio (H/F):1.33. The most common risk factor found is incoercible vomiting (5 patients), followed by chronic alcoholism (3 patients). Confusional state was the most frequent symptom found in 4 patients. The characteristic clinical triad of confusion, oculomotor disorders and ataxia was only found in 2 patients. Neuroimaging showed a typical aspect in 3 patients. The serum levels of thiamine were low in five patients and normal in two patients. After receiving parental than oral thiamin supplementation, three patients were independent after one month with a mRS score <3. Conclusions GWE is an acute neuropsychiatric emergency. Chronic alcoholism is recognized as its most common cause. The clinical triad is not constantly present. MRI shows typically bilateral symmetrical hyperintensities in periaqueductal area, periventricular region, thalami and mammillary bodies. Thiamin level can be normal since it does not accurately represent body thiamine status or in case of mutations in a thiamine-transporter gene. Thiamine therapy is warranted if any component of the GWE triad is present in an appropriate clinical setting to prevent irreversible neurological sequelae.

Abstract
In personalized medicine, a challenging task is to identify the most effective treatment for a patient. In oncology, several computational models have been developed to predict the response of drugs to therapy. However, the performance of these models depends on multiple factors. This paper presents a new approach, called Q-Rank, to predict the sensitivity of cell lines to anti-cancer drugs. Q-Rank integrates different prediction algorithms and identifies a suitable algorithm for a given application. Q-Rank is based on reinforcement learning methods to rank prediction algorithms on the basis of relevant features (e.g., omics characterization). The best-ranked algorithm is recommended and used to predict the response of drugs to therapy. Our experimental results indicate that Q-Rank outperforms the integrated models in predicting the sensitivity of cell lines to different drugs.

Abstract
Argan oil is precious oil with food and cosmetic uses. In recent years, this oil has been subject to an increasing national and international demand. The present work aims at studying the effect of clones and age, year of harvest and geographical origin on Argan oil quality and chemical composition. The results indicate that age does not affect Argan oil quality and fatty acids content. However, clones had a significant effect on fatty acids and tocopherol levels. Saturated and unsaturated fatty acids were highly influenced by the year of harvest and geographical origin, presumably due to climatic conditions. Unsaturated fatty acids varied from 78.28% to 81.77%. Depending on clones, total tocopherols varied from 687.40 mg/kg to 1068 mg/kg. This study is useful for the choice of clones with the aim of developing Argan trees orchards destined to oil production.

Abstract
IntroductionEpilepsy is a chronic disease defined as a brain disorder, characterized by a predisposition to present seizures, generating cognitive, psychological, and social consequences.ObjectiveTo determine the prevalence of psychiatric comorbid disorders in patients with epilepsy (PWEs) and its associated factors.MethodsWe conducted a cross-sectional study involving 30 PWEs who were treated in the neurology department of Habib Bourguiba Hospital in Sfax, Tunisia. We used the Mini International Neuropsychiatric Interview for the diagnosis of Axis I psychiatric disorders.ResultsThe half of patients had psychiatric comorbidities: 4 had major depressive disorder (MDD), 2 had MDD with generalized anxiety disorder, 4 had MDD with social phobia, 1 had bipolar disorder type I, 1 had panic disorder, 1 had agoraphobia and 2 had generalized anxiety disorder.Twenty-five PWEs had seizure-onset below 30 years old and among them, 40% had psychiatric comorbidities. Among patients who had seizure-onset above 30 years old, none had psychiatric comorbidities. Psychiatric comorbidities were found in 71.5% of patients with seizure frequency >2 per year. Psychiatric comorbidities were more common in patients with generalized seizures compared to whom with partial seizures (53% versus 45%). It was also more common in patients treated with polytherapy compared to whom with monotherapy (64% versus 37.5%).ConclusionThe prevalence of psychiatric comorbidities is relatively high among PWEs. The most frequent diagnoses found were mood and anxiety disorders. It is very important to identify them and treat them to enhance seizure control.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
PURPOSE, OBJECTIVE The aim of our study was to investigate the quality of life of patients undergoing cleft lip or cleft lip and palate as well as the perception of quality of life of patients perceived by their parents slot. PATIENTS AND METHODS Fifty-one adolescents and young adults (29 boys and 22 girls) who underwent cleft lip (FL 22) or lip and palate (CLP 29) and their parents have received psychological and surgical joint consultation. The minimum age for inclusion was 10 years (mean age 15.5 years). A quality of life questionnaire (VSP-A) "children" was given between 10 and 11 years and a questionnaire "adolescents" beyond. Parents have them answered a questionnaire of perceived quality of life of their children. The results were analyzed and compared to a control population (Statistics Student test). Perceived parents lived in relation to their children was obtained through the study of linear regression curves. RESULTS The response rate to the questionnaires was 66.7% for parents, 85.7% for children and 63.6% for teenagers. The quality of life of the patients was assessed by the patients to 65.1/100 on average. The index of overall quality of life was superimposed on the control population (p=0.66). Perceived quality of life of patients by their parents was fairly close to the quality of life described by patients (66.5). On the areas of family, education, recreation, quality index was proportionately less than for other areas. For each of these areas, parents overestimated the quality of life of their child. Compared to the control group the fields of education, leisure, vitality quality index were significantly lower in the/FL population P.

Abstract
PURPOSE We present the results of a new technique using a pedicled cutaneous flap for continent cystostomy. MATERIALS AND METHODS A total of 15 boys and 8 girls (mean +/- SD age 13.4 +/- 6.4 years) underwent continent cystostomy for neurogenic bladder (20), bladder exstrophy (2) and sequelae of hypospadias (1) between 1999 and 2008. In this procedure a rectangular pedicled flap is surgically elevated from a hairless area on the abdomen. The flap is tubularized and passed through the anterior abdominal wall directly into the bladder. A submucosal detrusor incision is made to expose the bladder mucosa, and the distal part of the flap is anastomosed to the bladder mucosa in a circular manner. The tube is positioned along the incised detrusor, which is closed over. Viability of the flap, self-catheterization management and continence status are then evaluated. RESULTS Mean +/- SD followup was 4.5 +/- 3.1 years. There was 1 case of distal necrosis of the flap, which required a secondary surgery using the Mitrofanoff technique. The 22 remaining flaps were initially viable, although 2 patients were eventually lost to followup and 3 subsequently presented with false-passage incidents requiring a few days of calibration using a balloon catheter. Dryness was achieved immediately in 73% of the cases. After adding a complementary bulking agent the dryness rate reached 77%. CONCLUSIONS We present a novel approach to continent cystostomy that is safe and easy to perform. This technique is a less invasive and more efficient alternative to other commonly used approaches.

Abstract
The therapeutic value of doxorubicin as an effective antineoplastic agent is limited by its cardiotoxic side-effects. The administration of doxorubicin (10 mg/kg) to male Wistar rats induced necrosis and apoptosis in heart tissues. It also caused oxidative stress damage as evidenced by the elevation of malondialdehyde and protein carbonyl levels and catalase activity, accompanied by the concurrent depletion of total antioxidant capacity and of superoxide dismutase level in cardiac tissues. The doxorubicin-induced cardiotoxicity and oxidative stress damage were also accompanied by increases of myeloperoxidase activity, total calcium content, and the expression of Bcl-2 protein in heart tissues. Most of these doxorubicin-induced biochemical and histological alterations were effectively attenuated by prior administration of purified standardized extract (1.5% withanolides; manufactured by Idea Sphere Inc., American Fork, UT, USA) of Withania somnifera (300 mg/kg). Thus, Withania may play a role in the protection against cardiotoxicity and thus might be a useful adjuvant therapy where doxorubicin is the cancer-treating drug.

Abstract
Integrins play an essential role in endothelial cell motility processes during angiogenesis and thus present interesting targets for the development of new anti-angiogenic agents. Snake venoms naturally contain a variety of proteins that can affect integrin-ligand interactions. Recently, the C-type lectin proteins (CLPs) have been characterized as efficient modulators of integrin functions. In this study, we investigated the anti-angiogenic activity of lebectin, a newly discovered CLP from Macrovipera lebetina venom. Human brain microvascular endothelial cells (HBMEC), used as an in vitro model, express alphavbeta3, alphavbeta5, and alpha5beta1 integrins, as well as the alpha2, alpha3, alpha6, and beta4 subunits. Our data show that lebectin acts as a very potent inhibitor (IC(50) approximately 0.5 nM) of HBMEC adhesion and migration on fibronectin by blocking the adhesive functions of both the alpha5beta1 and alphaV integrins. In addition, lebectin strongly inhibits both HBMEC in vitro tubulogenesis on Matrigel trade mark (IC(50) = 0.4 nM) and proliferation. Finally, using both a chicken CAM assay and a Matrigel trade mark Plug assay in nude mice, our results show that lebectin displays potent anti-angiogenic activity in vivo. Lebectin thus represents a new C-type lectin with anti-angiogenic properties with great potential for the treatment of angiogenesis-related diseases.

Abstract
PURPOSE OF THE STUDY Lagrange and Rigault stage IV extension type supracondylar fracture of the humerus (Gartland and Wilkins type III) involves major displacement, making treatment difficult. Several therapeutic methods have been described but indications vary considerably between teams. We conducted a retrospective analysis in order to evaluate the results of different methods, identify the most adapted technique, and detail the conditions necessary for good results with the collar and cuff immobilization method described by Blount. MATERIAL AND METHODS Forty-four children (30 boys and 14 girls), mean age seven years six months, were treated between January 1990 and December 2001. The collar and cuff immobilization technique was used for sixteen children (including four who underwent open revision for early secondary displacement), percutaneous pinning for two, and open crossed pinning for thirty (including four who developed secondary displacement after collar and cuff immobilization). One out of two collar and cuff treatments was instituted within six hours of injury. The four secondary displacements after collar and cuff immobilization treatment occurred after fracture reduction more than six hours after injury. The proportion of open reductions increased with longer delay to reduction after injury. Mean immobilization was three and a half weeks. The Flynn criteria were used to assess outcome at mean seven years eight months follow-up. RESULTS Outcome was satisfactory in all children treated with definitive collar and cuff immobilization and by percutaneous pinning; the rate was 97% after open procedures (persistent sequelae of radial palsy in one child). DISCUSSION Early treatment before six hours increased the chances of success with the collar and cuff method which remains the technique of choice for Lagrange and Rigault stage IV extension type supracondylar fractures. In the event of failure or complications, other classical methods should be discussed, including percutaneous pinning or direct access for open osteosynthesis.

Abstract
INTRODUCTION Lymphocele of the thoracic duct is a rare pathological entity occurring as a consequence of deterioration and cystic dilation wall of this vessel. It may be of congenital or degenerative origin. OBSERVATION We report the case of a 47 year old patient, operated on for a symptomatic cyst localised by CT scan to the inferoposterior mediastinum. At postero-lateral thoracotomy it was identified as a lymphocele and completely resected. Chemical analysis of the liquid and histopathology study of the cystic wall confirmed the diagnosis. The patient's post operative course was uneventful. CONCLUSION This case demonstrates the clinical characteristics of this entity and describes diagnostic techniques and surgical management.

Abstract
PURPOSE OF THE STUDY Congenital radio-ulnar synostosis blocks the wrist in a position of more or less pronounced pronation. The degree of pronation and possible bilateral involvement can compromise upper limb function. We propose percutaneous osteoclasis of the antebrachial skeleton to remedy this situation PATIENTS AND METHODS We performed 12 percutaneous rotation osteoclasis procedures. The objective was to weaken the metaphysodiaphyseal cortical periosteum of one or both of the forearm bones by intermittent perforations. This enabled derotation of the wrist which was maintained for six to eight weeks in a brachiopalmar cast. RESULTS Mean correction of pronation was 51 degrees. There were no cases of vascular or nervous complications and healing was uneventful. The esthetic outcome was very satisfactory. DISCUSSION Surgery is not indicated for all cases of synostosis. We retain for surgery patients presenting pronation at 60 degrees or more. At this degree of pronation, function is greatly compromised in adolescence, particularly if there is a bilateral involvement. Compared with other techniques, percutaneous osteoclasis is a simple safe and reliable technique. Reoperation is not required to remove material. The procedure is easier in young children, preferably at the age of 3 to 7 years, before the development of a functional handicap.

Abstract
As a part of an interdisciplinary research and action programme, morbidity and nutritional patterns were assessed in three nomadic communities: Fulani and Arab cattle breeders and Arab camel breeders, of two prefectures in Chad. The predominant morbidity pattern of Chadian nomadic pastoralists (representing approximately 10% of the total population of the country) had not been documented so far. A total of 1092 women, men and children was examined by a physician and interviewed during two surveys in the dry season and one in the wet season (1999--2000). Participants with no complaint were rare. Pulmonary disorders (e.g. bronchitis) were most often diagnosed for children under 5 years of age. Of the adult participants, 4.6% were suspected of tuberculosis. Febrile diarrhoea occurred more often during the wet season when access to clean drinking water was precarious. Malaria was only rarely clinically diagnosed among Arabs during the dry season, whereas Fulani, who stayed in the vicinity of Lake Chad, were also affected during this period. A 24-h dietary recall showed that less Arab women than men consumed milk during the dry season (66% versus 92%). Malnutrition was only documented for 3 out of 328 children (0--14 years). Arab women in childbearing age had a higher proportion of children not surviving when compared to Fulani women (0.2 versus 0.07). This study identified several implications for reseach and interventions in nomadic settings. Innovative and integrated health services for nomads can possibly be extended to many settings as nomadic pastoralists have in common a similar way of life driven by the needs of their animals.

Abstract
PURPOSE OF THE STUDY Chronic shoulder instability is uncommon in patients with an immature skeleton. Some of these pediatric patients can produce their dislocation voluntarily raising the question of the traumatic or constitutional nature of the condition as well as its direction and tolerance. We report our experience with 29 patients. MATERIAL AND METHOD Over a period of 28 years, 29 children aged 5 to 15 years were treated for voluntary shoulder dislocation. The dislocation was painful and poorly tolerated in 19, affecting daily life and sports activities. Posterior dislocation was observed in 15 patients and anterior dislocation in 4, but the direction was not always easy to establish, particularly in children with ligament laxity; multiple directions were not uncommon. Rehabilitation for at least eight months did not relieve pain in 11 patients who had a sensation of a blocked, unreliable shoulder which could not be controlled voluntarily. Posterior capsulorrhaphy was performed in 8 patients and anterior capsulorrhaphy in 3. RESULTS Mean follow-up was 8 years. At last follow-up, all shoulders were stable and shoulder motion was normal with no loss of function. More than half of the children had resumed sports activities. Capsulorrhaphy was proposed when the pre-operative explorations did not reveal any bone or rim anomaly. The only preoperative finding in the operated patients was increased capsule volume, particularly in the inferior portion. Intraoperatively, ulceration of the humeral cartilage was found in two patients. Anatomic reconstruction of the capsuloligamentary structures enabled recovery of passive stability and active stability of the scapulohumeral joint, preventing further voluntary dislocation.

Abstract
As a part of a research-and-action partnership between public health and veterinary medicine, the relationships between the seroprevalences of brucellosis and Q-fever in humans and livestock were evaluated in three nomadic communities of Chad (Fulani cattle breeders, and Arab camel and cattle breeders). Nomad camps were visited between April 1999 and April 2000. A total of 860 human and 1637 animal sera were tested for antibodies against Brucella spp., and 368 human and 613 animal sera for Coxiella burnetii. The same indirect ELISA was used for livestock and human sera, and the test characteristics for its use on human sera were evaluated. Twenty-eight people were seropositive for brucellosis (seroprevalence 3.8%). Brucella seroprevalence was higher in cattle (7%) than other livestock, and brucellosis seropositivity was a significant factor for abortion in cattle (OR=2.8). No correlation was found between human brucellosis serostatus and camp proportions of seropositive animals. Q-fever-seropositive blood samples were taken from 11 Arab camel and 4 Arab cattle breeders (seroprevalence 1%). Being a camel breeder was associated with Q-fever seropositivity in humans (OR=9). Camels had the highest Q-fever seroprevalence (80%) among livestock species. Although there was high-risk human behaviour for the acquisition of brucellosis and Q-fever from livestock through raw-milk consumption (98%) and contact with placentas of livestock (62%), we concluded that seroprevalences in humans were relatively low (likely due to limited active foci in livestock).

Abstract
The seroprevalences of brucellosis and Q-fever were evaluated in humans and livestock in three Chadian nomadic communities, i.e., Fulani cattle breeders and Arab camel and cattle breeders. The survey was carried out in 1999 and 2000. The total number of human sera and animal sera tested were 911 and 1637, respectively, for antibodies against Brucella spp. and 368 and 613, respectively, for Coxiella burnetii. Sixteen brucellosis positive human sera resulted in a seroprevelance rate of 2%. Male participants were significantly more often brucellosis seropositive than females. No association was found between brucellosis serostatus and physical findings or reported symptoms. Positive brucellosis serology was more frequent in cattle (seroprevalence, 7%) than in camels (1.4%) and small ruminants (0.5%). Fifteen human sera from 11 Arab camel breeders and 4 Arab cattle breeders were positive for Q-fever (seroprevalence below 1%). Being a camel breeder was a significant risk factor for Q-fever seropositivity. Camels had the highest Q-fever seroprevalence (73%) among livestock species.

Abstract
The purpose of this report is to describe a network of public health care workers, veterinarians and nomadic pastoralists that was set up in Chad to increase vaccination coverage to nomadic children and women who had rarely been vaccinated before. The objectives of the project were to provide human vaccination in conjunction with existing veterinary services, to evaluate the feasibility and limitations of such campaigns, to determine what other services could be provided concurrently, and to estimate the savings for public health care cases in comparison with carrying out vaccination separately. In a series of 12 vaccination campaigns in the Chari-Baguirmi and Kanem districts, more than 2100 children, 2100 women and 52000 cattle were fully immunized. These results confirmed the feasibility of joint campaigns in nomadic settings and provided important experience for improving organization. Information-Education-Communication (IEC) campaigns adapted to the realities of the pastoral setting were an important factor in mobilizing nomadic pastoralists for attendance at vaccination clinics. The savings in logistics costs (i.e., personnel, transportation and cold chain costs excluding vaccine costs) was 15% in Gredaya where 3 out of 6 campaigns were carried out together with veterinarians and 4% in Chaddra/Am Dobak where only 1 out of 6 campaigns was carried out in conjunction with veterinarians. The cost per fully immunized child (FIC) was considerably higher in Chaddra/Am Dobak than Gredaya (EUR 29.2 vs. EUR 11.5). The joint vaccination campaign approach is innovative, appreciated by nomadic pastoralists and less expensive than separate vaccination. By using the mobility of veterinarians in remote zones far from health care facilities, vaccination can be provided to nomadic children and women in countries with limited resources.

Abstract
Within the framework of an multidisciplinary research and action program, morbidity patterns were assessed in three nomadic communities, i.e., Fulani, Arab cattle breeders and Arab camel breeders, living in Chari-Baguirmi and Kanem, Chad. This is the first data about the health of Chadian nomadic pastoralists who account for approximately 6% of the total population. A total of 1092 women, men and children were interviewed and examined in the course of three surveys carried out by a physician during the dry and rainy season. Nomads reporting no health problems were rare. Tuberculosis was suspected in 4.6% of adults after clinical examination and bronchopulmonary disorders in children less than five years of age. Febrile diarrhea was more prevalent during the wet season when access to clean drinking water was more difficult. Simple malaria was rarely diagnosed in Arabs during the dry season. In contrast simple malaria was frequent in Fulani who stay in the vicinity of Lake Chad during the dry period. Protein-energy malnutrition was observed in only 3 of 328 children younger than 15 years of age.

Abstract
PURPOSE To discuss the usefulness of CT scan in initial management of well tolerated tracheobronchial injuries and the place of tracheoscopy. METHODS We report our experience of three cases treated for tracheobronchial rupture resulting from three different mechanisms and review the literature. Three boys, aged 4 to 10 years, were referred to our institution for tracheobronchial rupture. Two of them presented with subcutaneous emphysema after a minor trauma, the third was a polytrauma referred after a severe car crash and was already intubated. We emphasise the importance of an initial CT scan, as this allowed us twice to confirm the tracheal wound prior to tracheoscopy. We discuss the necessity of performing a tracheoscopy in the case of a well tolerated lesion, as this procedure clearly worsened the ventilatory state in one of our cases. Moreover, one of our cases illustrates the fact that even a minor trauma can lead to life-threatening respiratory distress. All the lesions observed in our study were linear and were managed by thoracic drainage; they were then closely monitored and required no further surgical procedure. CONCLUSION Tracheobronchial rupture in children can result from minor cervical traumas and in such cases special attention must be paid to mild discomfort or subcutaneous emphysema on admission. Initial CT scan can be very helpful in visualising the level of the rupture and its consequences with respect to the pulmonary parenchyma. One can question the necessity for tracheoscopy in well tolerated lesion, as its results do not always improve the therapeutic outcome.

Abstract
BACKGROUND Cardiovascular diseases are the leading cause of death in the Western world, especially in the elderly. Myocardial fibrosis induced by activated cardiac fibroblasts is thought to play a key role in the pathogenesis of cardiovascular disease. Accumulation of advanced glycation endproducts (AGEs), products of nonenzymatic glycation of proteins, correlate with the stiffness of the heart and large vessels. To elucidate a potential role of AGEs as a trigger of fibrosis, the effects of AGEs on primary fibroblasts from hearts of adult rats were investigated. MATERIAL AND METHODS The activation of intracellular signaling pathways was shown by Western blotting. In addition, the expression of genes of the extracellular matrix proteins, metalloproteases (MMPs), their inhibitors, and TGF-beta were analyzed by semiquantitative PCR. Activation of MMPs were controlled by Zymography. RESULTS It was shown that treatment of cardiac fibroblasts with AGEs leads to an activation of different signaling molecules, such as the p38MAP-kinase, the extracellular regulated kinases (ERKs), the jun kinase (JNK), as well as transcription factors like ATF-2 and NF-kappaB. In addition, the expression and activation of MMP-2, MMP-9, and MMP-13 were induced, which may be responsible for tissue remodeling followed by fibrosis. CONCLUSION Due to their effects on the expression and activation of metalloproteases, AGEs should be regarded as a potential therapeutic target for the prevention of pathologic remodeling.

Abstract
BACKGROUND/PURPOSE Tracheobronchial ruptures in blunt thoracic trauma in children are rare. The aim of this study was to suggest the means of an early diagnosis and a conservative management as often as possible. METHODS Sixteen cases of tracheobronchial ruptures by blunt thoracic trauma were observed over 26 years in 9 regional pediatric centers. RESULTS There were 12 boys and 4 girls, from ages 1 hour to 17 years. Nine children presented with associated lesions. Fibroscopy established the following diagnosis: 8 tracheal wounds and 8 bronchial wounds. Six children were operated on within 18 hours (on average) after installation of a thoracic drainage. Two lobectomies, 3 ideal tracheal sutures, and 1 bronchial suture were performed. Seven children were treated exclusively by thoracic drainage. Two of them were intubated through the lesion, leading to a transitory endoprothesis accompanied or not by an external thoracic drainage. One infant recovered spontaneously. There were no deaths in this series. Two recurrent postoperative nerve injuries were noted, one of which was a transitory spontaneously resolutive scar bud and one a granuloma treated by laser. Three times, a stenosis occurred after a conservative management. Two were operated on. CONCLUSIONS Tracheobronchial ruptures in children are rare. An early fibroscopy holds an important place in the approach of this pathology. Treatment is variable, based on thoracic lesions, their tolerance by the child, and associated lesions. Surgery is not the only therapy because conservative treatment by simple thoracic drainage or lesion intubation has proved effective.

Abstract
The authors present the results of a survey conducted among French paediatric urologists belonging to the Groupe d'Etudes en Urologie Pédiatrique (GEUP) (Paediatric Urology Study Group). This study, based on 122 cases observed in 13 centres, is not exhaustive, but is nevertheless statistically significant. The preoperative assessment confirms the usual findings of urinary stones in children: pyelonephritis, haematuria and abdominal pain, the usual presenting complaint, concomitant malformative uropathy (10% of cases) and a predominance of calcium stones. More than 200 stones were treated, larger than 10 millimeters in diameter in one-third of cases. Renal stones, mainly caliceal (more than 50%), included 11 staghorn calculi. This study also included 22 ureteric stones, mainly in the pelvic ureter, and 2 bladder stones. Lithotripsy was ultrasound-guided in 2/3 of cases and required general anaesthesia in about 3/4 of cases. Ureteric catheterization was required in 19 infants preoperatively, but in only 2 infants (stein strasse) postoperatively. One or two lithotripsy sessions were sufficient in most cases, but 4 sessions were necessary in 5 patients, to the same kidney in 1 case. The mean hospital stay was 2 to 3 days, but the procedure was performed on an outpatient basis in 15 cases. The immediate postoperative course was uneventful and asymptomatic. This survey revealed about 10% of complete failures, corresponding to solitary caliceal stones in 2/3 of cases; 29 partial failures were essentially due to lower caliceal stones and staghorn calculi; 84 successes (stone-free), mainly pelvic or simple caliceal stones. Scintigraphy did not reveal any immediate postoperative impairment of renal function. This study reported a success rate of about 70%, regardless of the type of apparatus used. Assessment of the results of ESWL requires sufficient follow-up both concerning the outcome of fragmented stones and evaluation of possible functional repercussions. This survey defines the main indications: although ESWL can be applied to most stones, some stones constitute poor indications (cystine stones, stenotic malformative uropathy) or dubious indications: small lower caliceal stones, densely calcified staghorn calculi in older children. This study confirmed the efficacy and low morbidity of ESWL in children. A prospective study needs to be conducted according to a rigorous protocol in order to refine the technique and indications while reducing the possible long-term risks.

Abstract
BACKGROUND Intestinal microsporidiosis is a major cause of chronic diarrhea and malabsorption in patients with human immunodeficiency virus. Its occurrence in transplant recipients has exceptionally been reported to date. METHODS We report what we believe are the first two cases of intestinal microsporidiosis in renal transplant recipients. The patients were treated with mycophenolate mofetil. RESULTS The clinical presentation was chronic diarrhea with massive weight loss. Stool analysis revealed microsporidian spores, identified as Enterocytozoon bieneusi spores by polymerase chain reaction. The onset of this opportunistic infection in these two patients is believed to be secondary to an increase in immunosuppression after azathioprine replacement by mycophenolate mofetil. The withdrawal of mycophenolate mofetil led to clinical recovery. CONCLUSION The incidence of microsporidiosis will probably increase in transplant recipients treated with powerful immunosuppressants. Therefore, we recommend a systematic search for microsporidian spores in stool specimens in cases of unexplained diarrhea in these patients.

Abstract
OBJECTIVES To determine systemic and local platinum concentrations released from subcutaneously implanted cis-diamminedichloroplatinum (cisplatin) -impregnated polymethylmethacrylate (PMMA) and to evaluate systemic or local adverse reactions. ANIMALS 6 healthy dogs. PROCEDURE Cisplatin (20 mg) was inserted into PMMA that was fashioned into cylinders and placed into subcutaneous tissue chambers overlying the thorax (treated site). An empty tissue chamber was placed over the opposite side (control site). Plasma samples were obtained for platinum determination before implantation, at 3, 6, and 12 hours after implantation on day 0, and once daily on days 1, 2, 3, 7, 14, 21, and 29. At similar times on similar days, tissue chamber fluid samples also were obtained for platinum determination. Complete blood count, serum urea nitrogen and creatinine concentration determinations, and urinalyses were performed on days 1, 2, 3, 7, 14, 21, and 29. Complete necropsy was performed at conclusion of the study. RESULTS Tissue chamber platinum concentrations at the treated site were significantly greater than plasma and control site tissue chamber concentrations on days 2, 3, 7, 10. Mean plasma platinum concentration at 3 (0.735 microg/ml), 6 (0.691 microg/ml), 12 (0.534 microg/ml), 24 (0.131 microg/ml), 48 (0.2 microg/ml), 72 (0.1 microg/ml), and 158 (0.014 microg/ml) hours was significantly greater than pretreatment values (0.0 microg/ml). Plasma platinum concentration 10 days after treatment (0.011 microg/ml) did not significantly differ from pretreatment values. Local or systemic adverse reactions were not apparent. CONCLUSIONS The route of cisplatin administration was safe. Greater concentration of platinum was released locally relative to plasma concentration for an extended period.

Abstract
108 children with repeated urinary tract infection were examined both with direct contrast cystography and radionuclide cystography. There was a good correlation between the two procedures in the majority of the cases (79), but in 21 cases, direct radionuclide cystography alone was positive and for 8 other children, direct contrast cystography showed a low-grade vesico-ureteric reflux even though radionuclide cystography was negative. When comparing the two procedures and taking into consideration the age of the patients we find that radionuclide cystography is more sensitive to detect vesico-ureteric reflux in the younger population (p < 0.02). This advantage is less clear for older children who more often present a low-grade reflux. Low radiation exposure is also a great advantage of radionuclide cystography, but anatomic definition is better with contrast cystography. It seems thus that the two procedures complement rather than rival each other. Their respective interest for evaluation of repeated urinary tract infection in children therefore depends on age, attain-ability of the procedure, and the possibility of a bladder or ureteral abnormality. Quite a few authors consider radionuclide cystography as at least as valid as contrast cystography, and even more sensitive. We have attempted to compare both procedures and to determine their respective role in repeated urinary tract infection exploration.

Abstract
We tested the carbon substrate assimilation patterns of 40 Corynebacterium amycolatum strains, 19 C. minutissimum strains, 50 C. striatum strains, and 1 C. xerosis strain with the Biotype 100 system (bioMérieux, Marcy-l'Etoile, France). Twelve carbon substrates of 99 allowed discrimination among the species tested. Additionally, assimilation of 3 of these 12 carbon substrates (maltose, N-acetyl-D-glucosamine, and phenylacetate) was tested with the API 20 NE identification system (bioMérieux). Since concordant results were observed with the two systems for these three carbon substrates, either identification system can be used as a supplementary tool to achieve phenotypic differential identification of C. amycolatum, C. minutissimum, and C. striatum in the clinical microbiology laboratory.

Abstract
PURPOSE OF THE STUDY Rickets secondary to bone or soft tissue tumors are rare in children. Majority of the reported cases occurred in adults older than thirty. This entity can be cured after tumor removal. The authors present a case in a ten year boy and literature review. MATERIAL A ten year boy complained of diffuse bone and muscle weakness for two years. A diagnosis of arthritis was made but the patient continued to complain. Serum calcium level was normal (2.33 mmol/l), phosphorus was very low (0.43 mmol/l), serum alkaline phosphatase was high, parathyroid hormone and vitamin D level were normal. Urinalysis showed abnormal phosphate excretion. METHODS The absence of malabsorption, no family history of rickets or hypophosphatermy presence of a marked excess of urinary phosphate, very low serum phosphate and normal serum calcium, vitamin D and parathyroid hormone levels led us to consider a diagnosis of tumor induced osteomalacia. Radiographs showed a large round radiolucent lesion in the left superior pubic ramus and generalized demineralisation. RESULTS We performed a complete tumor resection and the space was filled with bone graft. On histopathologic examination it was a benign mesenchymal tumor. Rapid reversal of biochemical anomalies, radiographs anomalies and clinical manifestation were observed after complete tumor resection. DISCUSSION The authors have described the tumor, the osteomalacia and the pathogenesis of tumor rickets. Histologically the most common causative tumors were vascular tumors, mesenchymal tumors and non ossifying tumors. The tumor were of bone or soft tissue origin. Clinical symptoms were muscular weakness, bone and muscle pain. Biochemically there is a very low phosphate level, a normal serum calcium level as well as a normal vitamin D and PTH level. There is a significant high level of urinal phosphate. The mechanism proposed to explain oncogenic osteomalacia includes tumor secretion of phosphaturic substance other than PTH and calcitonin. Another hypothesis is a substance interfering with normal vitamin D metabolism. The pathogenesis is not clearly defined. CONCLUSION Regardless to the mechanism of osteomalacia, complete removal of the tumor will cure the patient. A diligent search for tumors should be done in patients with vitamin D resistant rickets.
