Establishment of a multimodal protocol combining a motivational interview, subcutaneous injection of NicoSan® and hyper-hydration for the "stopsmoking therapy": A multicentre real-life study'.

OBJECTIVES: The StopSmoking Therapy, combins a motivational interview, a subcutaneous injection of NicoSan® and a hyperhydration protocol. The objectives were to evaluate the number of patients declaring cessation and factors related to relapse. METHODS: In the 18 months following protocol, 554 subjects who consented, responded to the study's questionnaire. Categorical variables are presented as the frequency and percentage, continuous variables are presented as the mean and standard deviation, responses of abstinent subjects and of those who had started smoking again are compared via the chi-square test for categorical variables, and the Student's t-test for continuous variables. RESULTS: In our sample 92.8% of the subjects reported smoking for 10 years or more. A total of 475 subjects (85.7%) reported a complete cessation (31.2% for more than 6 months and 33.1% for more than a year). Among relapsing subjects, were significantly over-represented: youngest ages, lower motivation, more frequent close friends or family using tobacco, lower dependency scores. No subject reported any significant adverse effects. CONCLUSION: The multimodal protocol explored seems to have a favorable impact on smoking cessation, which could be enhanced by additional interventions dedicated to the youngest age groups, to people having smoking close friends and family, and should possibly add interventions based on cognitive behavioral therapy. A dedicated support by specialist tobacco addiction in the first weeks after treatment and/or the use of mobile support applications could also be useful. In order to asses efficacy, a prospective randomized double blind controlled versus placebo protocol could be considered.

[Inherited kidney stones: A nephrology center experience]. / Lithiase urinaire héréditaire : expérience d'un service de néphrologie.

INTRODUCTION: Genetic factors must be considered in etiological diagnosis of urinary lithiasis. The aim of this study was to determine clinical, metabolic characteristics and the progression of hereditary urinary lithiasis in our patients. METHODS: A retrospective study was conducted between 2008 and 2018 and 60 patients were included. Patients were referred to our department from pediatrics departments to be followed-up in adulthood in 9 cases, for etiological investigation in 42 cases and for chronic renal failure in 9 cases. RESULTS: Thirty-five men and twenty-five women were enrolled in this study with a M/F sex ratio equal to 1.4. The mean age at the time of diagnosis of the hereditary character of the urinary lithiasis was 28.6years (3months-63years). The average delay between the onset of the lithiasis disease and the etiological diagnosis was 8years (0-42years). We noted 31 cases of cystinuria, 18 cases of primary hyperoxaluria type 1 with two mutations (I244T in 14 cases, 33-34 Insc in 23 cases) and 11 cases of renal tubulopathy. Fourteen patients were affected with chronic renal failure, of which five were in the end-stage renal disease. Crystalluria was positive in 62% of cases. The morpho-constitutional analysis of stones was performed in 37 cases and it contributed to the diagnosis in 29 cases. After an average follow-up of 16years, we noted normal renal function in 42 cases, chronic renal failure in 7 cases, hemodialysis in 10 cases all with primary hyperoxaluria and transplantation in 1 case. CONCLUSION: The etiological diagnosis of hereditary urinary lithiasis in our study was made with considerable delay. Cystinuria was the most frequent etiology and primary hyperoxaluria was the most serious affection. LEVEL OF EVIDENCE: 4.

Impact of Interleukin-17F Gene Polymorphisms in Outcome of Kidney Transplantation in Tunisian Recipients.

BACKGROUND: Genetic polymorphisms of interleukin (IL)-17F, associated with functional and/or quantitative change in this glycoprotein, have been described as predisposing to various autoimmune diseases. The proinflammatory IL-17 has some roles in renal transplantation. In this context, the relationship between the most common IL-17F polymorphisms with acute renal allograft rejection susceptibility in Tunisian renal recipients has been investigated. METHODS: We examined 93 renal transplant recipients who were enrolled and classified as follows: GI, 48 transplant recipients who developed at least one episode of acute rejection; and GII, 45 controls, kidney recipients who also were followed for at least 1 year and had stable renal function. Single nucleotide polymorphisms (SNPs) of IL-17F gene, including -1507 C/T (rs18889570), 7384 A/G (rs2397084), 7469 C/T (rs11465553), and 7489 A/G (rs763780), were evaluated using direct sequencing. RESULTS: No statistically significant association of the IL-17F SNPs studied with the onset of acute rejection was observed. However, AA genotype on 7489A/G SNP showed anti-HLA antibodies less than other genotypes and a higher graft survival time (P = .017). CONCLUSION: The AA genotype on 7489A/G SNP of IL-17F and the A allele might be associated with a lower risk of acute rejection with better graft survival.

Right ethmoid eosinophilic angiocentric fibrosis with orbital extension.

INTRODUCTION: Eosinophilic angiocentric fibrosis (EAF) is a slowly progressive, benign disease involving the mucosa of the upper airways or, more rarely, the orbit. It belongs to the spectrum of IgG4-related disease. CASE REPORT: The authors report the case of a 61-year-old man who presented with orbital involvement (visual loss, pain, proptosis, and eyelid oedema), headache and nasal obstruction. Imaging revealed a right ethmoido-orbital mass infiltrating the periorbital fat and enveloping the optic nerve. Histological examination concluded on a diagnosis of EAF in the presence of perivascular infiltration by inflammatory cells, predominantly eosinophils, and zones of "onion skin" fibrosis. Immunohistochemistry attributed these lesions to IgG4-related disease. Initial treatment with corticosteroids followed by dapsone failed to control the disease and resulted in severe steroid dependence. Surgical ethmoidectomy with resection of the lamina papyracea was performed to allow displacement of the eyeball into the nasal cavity in the event of another episode. DISCUSSION: The combination of surgery and rituximab achieved lasting pain relief with no recurrence of exophthalmos.

Visceral leishmaniasis in adults with nephropathy.

The aim of this study is to evaluate the features of visceral leishmaniasis (VL) in adults with nephropathy, who were not infected with the human immunodeficiency virus. This is a retrospective study of 14 adults hospitalized between 2000 and 2014, with VL and renal involvement. Clinical, biological, and therapeutic data were collected from the patients' medical files. Eleven women and three men, most of whom were from the North of the country, with a mean age of 40.5 years were studied. Lupus was present in five cases, the Sicca syndrome in three cases, diabetes in one case, renal failure on dialysis in two cases, and there were three renal transplant recipients. Major clinical symptoms were fever and weakness in all cases. Enlargement of the spleen was present in eight cases and hepatomegaly in six cases. Biologic inflammatory syndrome and anemia were present in all cases, and pancytopenia was present in seven cases. Renal insufficiency was noted in all cases. Diagnosis of VL was confirmed by bone marrow examination or serology. Treatment consisted of antimoniate in 10 cases and amphotericin B in four cases. Seven deaths were recorded. Clinical symptoms of VL are atypical in patients with nephropathy and therefore, the diagnosis should be suspected in such patients because VL is still endemic in our country.

Insights on stock structure of round sardinella Sardinella aurita off north-west Africa based on otolith shape analysis.

This study examines the geographic variability in otolith shape of round sardinella Sardinella aurita as a tool for stock discrimination. Fish were analysed from six sampling locations from Senegal to the Mediterranean coast of Morocco. A combination of otolith shape indices and elliptic Fourier descriptors was investigated by multivariate statistical procedures. Within the studied area, three distinct groups were identified with an overall correct classification of 78%. Group A: Nador (Alboran Sea), group B: Casablanca (northern Morocco) and group C: Senegalese-Mauritanian. The results of this study confirm the absence of an Atlantic Ocean-Mediterranean Sea transition for this species, the Gibraltar Strait acting as an efficient barrier for S. aurita population separation. Off north-west Africa, fish from northern Morocco form a single group which is clearly isolated from Senegalese-Mauritanian waters, confirming the existence of a distinct stock in this area. Among group C, some discontinuity exists and suggests the existence of a sedentary fraction of S. aurita in northern Mauritania (Arguin Bank). The results are discussed in relation to oceanographic features and physical barriers to dispersal and fish management strategy in the study area.

Controversies on Transvaginal Ultrasound Screening for Endometrial Cancer in Asymptomatic Postmenopausal Women.

Endometrial cancer (EC) in postmenopausal women is usually associated with abnormal vaginal bleeding. However, asymptomatic cases of EC have been reported. The incidence of EC has been estimated to 1.3-3.05 per 1,000 screened postmenopausal asymptomatic women, the most significant ultra-sonographic feature being the thickened endometrium. We reviewed the literature on the accuracy of endometrial thickness measurement by transvaginal sonography (TVS) in predicting EC in asymptomatic postmenopausal women. The use of endometrial thickness as a sole screening test was found not to be of high predictive value and it should be combined with the evaluation of EC risk factors and followed by hysteroscopy and biopsy in suspicious cases. The lack of a universal cut-off value for endometrial thickness that could be correlated to EC is pointed out.

Toll-like receptor 4 and CD14 gene polymorphisms in Tunisian kidney transplantation.

BACKGROUND: Acute and chronic rejections remain an important cause of graft loss after renal transplantation. Currently, activation of innate immune responses through Toll-like receptors (TLRs) is suspected to be implied in the loss of the transplant tolerance. OBJECTIVES: We investigated functional single nucleotide polymorphisms (SNPs) of TLR4 and its coreceptor CD14 in kidney transplantation and looked for any potential role in acute rejection (AR) and chronic allograft nephropathy (CAN) and impact on graft survival. PATIENTS AND METHODS: TLR4 (Asp299Gly) and CD14 (C/T -159) SNPs were detected using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 209 kidney transplant recipients (KTRs) including 132 treated with mycophenolate mofetil (MMF+). AR occurred in 59 patients and 24 were identified as having CAN by biopsy and scored according to the Banff criteria. RESULTS: There were no significant associations between TLR4 and CD14 genotypes and alleles and the occurrence of both AR episodes and CAN. Moreover, TLR4 and CD14 SNPs did not seem to influence kidney graft survival. Analysis according to human leukocyte antigen (HLA) compatibility status, positivity of anti-HLA antibodies, and immunosuppression by MMF confirmed the absence of correlation of the investigated SNPs with the graft outcome. In addition, incidence of post-transplantation infections, including cytomegalovirus (CMV) infections, was not influenced by both TLR4 and CD14 SNPs. CONCLUSION: These results suggest that TLR4 (Asp299Gly) and CD14 (C/T -159) functional SNPs do not play a major role in AR, CAN, and kidney graft survival. Therefore, intragraft monitoring of TLR4/CD14 genes expression by messenger RNA (mRNA) would provide clarity on the exact role of these receptors in graft injuries.

Malformative uropathies and kidney transplantation.

INTRODUCTION: Malformative uropathies are a frequent cause of end-stage renal disease (ESRD) requiring renal replacement therapy (RRT). Medical management of urinary tract infections and advances in surgical reconstruction procedures resulted in good outcomes of kidney transplantation among these patients. The aim of this article was to describe the epidemiological profiles and outcomes of patients who underwent transplantation for ESRD related to malformative uropathies. PATIENTS AND METHODS: Among 493 kidney recipients at our center from 1986 to 2009, 47 had malformative uropathies as the cause of ESRD. We retrospectively studied the incidence of acute rejection episodes, acute tubular necrosis, as well as patient and graft survivals, comparing these results to those observed in patients without malformative uropathies using chi-square tests for qualitative parameters and nonpaired Student t tests for continuous variables. Log-rank tests were used for comparisons of survival curves. RESULTS: The 47 patients, representing 9.53% of our kidney transplant recipients, included 27 men and 20 women (sex ratio=1.35) with an overall mean age of 27.6±9.1 years (range, 10-49). The common etiology was vesico-ureteral reflux (78.7%). Hemodialysis was the main RRT modality (68%) with a median duration of 41 months. Also, 82.9% of patients received transplants from living donors. Acute tubular necrosis occurred in 4 of these (8.5%) versus 22.06% of the other patients (P=.03). Acute rejection episodes were observed in 13 of these patients (27.6%) versus 23.1% of the other patients (P=not significant [NS]). After a cumulative follow-up period of 3744 months (median, 41.8 months), 5 patients had died (1.6 death/y/100 patients) and 5 had lost their allografts and returned to dialysis (1.6 case/y/100 patients). Graft survival rates at 1, 5, and 10 years were 97.8%, 93.2%, and 79.9%, which were comparable with 95.9%, 87.6%, and 78.9% among the other patients, respectively (P=NS). Patient survival rates at 1, 5, and 10 years were 100%, 88.5%, and 82.6% versus 96%, 87.6%, and 79.6%, respectively (P=NS). CONCLUSION: Kidney transplantation in patients with malformative uropathies is increasingly frequent. The incidence of acute rejection episodes as well as patient and graft survivals were comparable with those of subjects without malformative uropathies.

[Affective temperaments in the bipolar and unipolar disorders: distinctive profiles and relationship with clinical features]. / Tempéraments affectifs dans les troubles bipolaires et unipolaires : comparaison des profils tempéramentaux et relation avec les caractéristiques cliniques.

INTRODUCTION: Recent research postulated that temperaments represent the subclinical foundations of affective disorders, and an early clue for a recurrent, prebipolar disorder. Akiskal et al. operationalized five types of temperaments: depressive, hyperthymic, irritable, cyclothymic and anxious. The aims of this study were to compare the affective temperaments scores in patients with bipolar I, II and recurrent depression disorders and to explore the relation between temperaments scores and clinical features of those affective disorders. METHODS: This was a comparative cross-sectional study, concerning three groups: patients with bipolar I disorder (BIP I) (n=31, 20 men and 11 women, mean age=42.0+/-10.1 years), patients with bipolar II disorder (BIP II) (n=18, 11 men and seven women, mean age=40.7+/-10.8 years) and patients with recurrent depressive disorder (RDD) (n=66, 28 men and 38 women, mean age=45.0+/-9.3 years). All patients were in remission of a major depressive episode. The affective temperaments were assessed by the Akiskal and Mallya Affective Temperament questionnaires. RESULTS: Hyperthymic temperament mean scores were higher in BIP I (10.8+/-5.4) and BIP II (10.3+/-5.5) groups compared to RDD group (5.5+/-4.0) (p<10(-3)). Depressive temperament mean score was significantly higher in RDD group (10.5+/-4.3), compared to BIP I (7.3+/-4.6) and BIP II (5.4+/-2.9) groups (p<10(-3)). Cyclothymic temperament mean score was higher in BIP II group (4.7+/-5.8) compared to BIP I (3.3+/-3.9) and RDD (2.5+/-3.9) groups, but this difference was not significant (p=0.08). No difference was found between the three groups concerning irritable temperament scores. Negative correlation was found between hyperthymic and depressive temperament scores in BIP I (r=-0.81, p<0.001) and RDD (r=-0.73, p<0.001) groups, but not in BIP II group. Concerning the clinical correlates with affective temperament scores, negative correlation was found between hyperthymic temperament score and number of depressive episodes in BIP II group (r=-0.53, p=0.02). Hyperthymic temperament score was associated with psychotic features in the last depressive episode in BIP I (p=0.01) and BIP II (p=0.008) groups and seasonal features in BIP II group (p=0.02). Moreover, cyclothymic temperament score was associated with psychotic (p=0.009) and seasonal features (p=0.03) in BIP II group. CONCLUSIONS: Despite the small sample sizes for our study groups, we can conclude that hyperthymic and cyclothymic temperaments characterized bipolar disorders and are correlated with other markers of bipolarity such as psychotic and seasonal features. Thus, temperament assessment might become a useful tool to predict bipolarity in association with those markers.

[Primitive pleural hydatid cyst: case report]. / Kyste hydatique pleural primitif: a propos d'une observation.

Even in endemic countries, the primitive pleural hydatid cyst is exceptionnal and it's very difficult to distinguish from other pleural and parietal cystic masses all the more the immunologic tests are negative. We report the case of a primitive pleural hydatid cyst diagnosed in 43 years old man. Throug this case, imaging features are emphasized.

[Atypic radiologic aspect of a renal cell carcinoma in children]. / Présentation radiologique atypique d'un carcinome à cellules claires du rein chez l'enfant.

Renal cell carcinoma is rare in children and is usually found in late childhood. The authors report on an exceptional case of renal cell carcinoma in a 10-year-old girl. The radiological aspect is misleading and has not been previously reported in the literature. Renal cortex was thin because of congenital megalo-ureter, so the tumor developed entirely into excretory cavities (to the proximal ureter), while a primitive urothelial disease (tumoral or inflammatory) was first evoked. The atrophied cortex was the tumoral starting point which prolapsed into excretory cavities, upraising the urothelial epithelium.
