[Urinary tract symptoms in Lewy body dementia: About 19 cases]. / Les troubles urinaires de la maladie à corps de Lewy. À propos de 19 cas.

INTRODUCTION: Lewy Body Dementia (LBD) is a Parkinsonian disorder which often leads to Lower Urinary Tract Symptoms (LUTS), especially an Overactive Bladder (OAB). There have been few LBD related LUTS depictions in the literature, which is why we did this retrospective study. METHODS: Retrospective single institution study. RESULTS: Nineteen patients with confirmed LBD diagnosis were found, (63% of men, mean age 74 years old). The main symptom was OAB (100% of patients) with frequent stress urinary incontinence (94%) associated with detrusor overactivity (93%) with pressure elevation (79%). Voiding difficulties were found in 16% of medical interviews, and in 53% of urodynamics. In total, 92% of patients complained of constipation, with 44% suffering from fecal incontinence. DISCUSSION: LBD is characterized by alpha-synuclein aggregates in the cerebral cortex, thus explaining associated cognitive impairment. The most commonly found LUTS is stress incontinence. We also found voiding difficulties in smaller proportion, sometimes associated with prostatism. Topographically, these symptoms could be explained by alpha-synuclein aggregates in the frontal and temporal cortex and the pons. Anorectal disorder and sexual dysfunction were frequently associated. Urological complications are scarce in this population, screening is focused in increasing quality of life, and the possibility to discriminate the different types of Parkinsonisms. CONCLUSION: OAB is the most common lower urinary tract symptom in LBD often associated with detrusor overactivity, and less frequently voiding difficulties sometimes associated to prostatism. LEVEL OF EVIDENCE: 3.

[Neuroanatomical correlates between stroke lesions and urinary disorders: A narrative review]. / Corrélats neuroanatomiques entre lésions AVC et troubles urinaires : une revue de la littérature.

CONTEXT: Stroke generates diverse urinary disorders, frequent but often under-diagnosed and thus untreated. Even though advances in the comprehension of the physiological voiding control and involved brain areas, the precise correspondence between lesion sites and observed urinary symptoms is not clearly established. OBJECTIVE: This review aimed to update on this neuroanatomical correlates. DOCUMENTARY SOURCES: The search focused on articles written in French or English, on PubMed, studying human beings or animals, published between the 1st of January 2000 and the 31st of August 2018 using the following keywords (stroke or hemiplegia) and (urinary incontinence or low urinary tract symptom or retention or overactive bladder or dysuria) and (anatomy or location or localization or area or lesion). STUDIES SELECTION: The main author selected the most pertinent articles on abstracts and then on full text. RESULTS: Twelve studies were included in our review. We could not fully confirm the neuroanatomical correlates based on the animal model. Frontoparietal lesions in urinary incontinence, role of the insula in the urinary retention, and systematic but different urinary symptoms in the brain stem lesions are the main findings. LIMITS: Few studies were included, with varying methodologies and types of population. CONCLUSION: A few cerebral areas damaged by stroke seem to be linked to certain urinary troubles, but new studies with a higher methodological quality are required to confirm this result.

[Seniority of neurobladder and effectiveness of a first intradetrusor injection of botulinum toxin]. / Ancienneté de la neurovessie et efficacité d'une première injection de toxine botulique intradétrusorienne.

UNLABELLED: Intradetrusor injection of botulinum toxin is one of the second-line therapy of neurologenic detrusor overactivity. GOAL OF THE STUDY: In 26% to 66% of the cases, intradetrusor injection of botulinum toxin is inefficient in order to reduce overactive bladder symptoms and/or overactive detrusor. The objective of this study is to determine whether it exists a link between the efficacy of the first IDBT and the length of neurological detrusor overactivity symptoms. METHODS: Retrospective study on 79 patients which have a first intradetrusor injection of botulinum toxin between January 2001 and December 2013. Inclusion criteria were patients older than 18 and having neurological detrusor overactivity. RESULTS: There is no significant difference of intradetrusor injection of botulinum toxin efficacy according to duration of urinary symptoms in the general neurologigal population (multiple sclerosis, spinal cord injury, spinal cord compression, ischemic pathology, infectious pathology) with the mean age being 46 years. On the contrary, the length of evolution of neurological detrusor overactivity symptoms before the intradetrusor botox injection therapy and the efficiency of the first intradetrusor injection of botulinum toxin seem to be correlated with negative results in patients with multiple sclerosis. CONCLUSIONS: The duration of urinary symptoms is a predictive factor of primary failure of intradetrusor injection of botulinum toxin in multiple sclerosis patients, in univariate analysis.

[Translation and linguistic validation in classical Arabic of the urinary symptom profile (USP) questionnaire]. / Traduction et validation linguistique en Arabe classique du questionnaire de l'urinary symptom profile (USP).

OBJECTIVE: The objective was to translate and linguistically validate in classical Arabic; the French version of the Urinary Symptom Profile (USP), the scale adapted to vesico-sphincter disorders. PATIENTS AND METHODS: Prospective study of 30 patients suffering the vesico-sphincter disorders. The translation was obtained by the method: translation back-translation. Patients completed the final questionnaire on day 0 and day 15. The feasibility, acceptability, internal consistency using Cronbach's alpha and test-retest repeatability by the interclass correlation coefficient (ICC) with the confidence interval (CI) were studied. RESULT: The sample consisted of 30 subjects including 20 men (66.6%) and 10 women (33.3%). The mean age was 48±18, 14 years ranging from 25 to 70 years. The questionnaire was feasible and acceptable. The Cronbach's alpha of the three dimensions, urinary stress incontinence, overactive bladder and voiding difficulties was respectively 0.9880, 0.9774 and 0.9683, respectively; the ICC was 0.9762 (95% CI: 0.9307-0.9919), 0.9558 (CI 95%: 0.8738-0.9849) and 0.9385 (95% CI: 0.8274-0.9789). CONCLUSION: The Arabic version of the classic USP had excellent internal consistency and excellent repeatability enable a full assessment of all urinary disorders and their severity.

[Bladder deformations in neurogenic bladder secondary to cauda equina or conus medullaris lesion]. / Signes de lutte dans les vessies neurologiques des lésions de la queue de cheval et du cône terminal.

INTRODUCTION: The bladder deformations observed in the neurogenic bladders are frequent, particularly in the "upper motor neuron" bladder type (paraplegia, multiple sclerosis). We wanted to verify the predictive factors of such damage and particularly, if the urodynamic typology intervened in their genesis by using the model of cauda equina syndrome and conus medullaris lesions. PATIENTS AND METHODS: We have studied retrospectively the presence of cystographic bladder deformations at patients with neurogenic bladder due to cauda equina syndrome or conus medullaris lesion according to their urodynamic status: either overactive or acontractile detrusor. RESULTS: Of 68 patients, (mean age 47.2 years), 34 had an overactive and 34 an acontractile detrusor. The presence of bladder deformations was associated with an overactive detrusor (p=0.04). However, 50% of the patients with acontractile detrusor had bladder deformations, and those deformations were associated with male sex, and this excluding urologic obstruction. CONCLUSION: This study demonstrates the existence of bladder deformations in the hypoactive lower motor neuron neurogenic bladder type. If the bladder deformations seem more frequent in the overactive neurogenic bladder type, their specific and repeated search is also necessary during the follow-up of the lower motor neuron neurogenic bladder type.

[Breast cancer and Axillary Reverse Mapping]. / Cancer du sein et Axillary Reverse Mapping Pigment d'un tatouage décoratif au niveau d'un ganglion axillaire non sentinelle.

We report a case of T1N0 left breast cancer in a 47-year-old woman. Histopathological examination of a non sentinel axillary lymph node showed a pigmentation due to a decorative tattoo of the arm. The authors discuss a new concept: Axillary Reverse Mapping.

Sequence of the canine herpesvirus thymidine kinase gene: taxon-preferred amino acid residues in the alphaherpesviral thymidine kinases.

Multiple sequence alignments of evolutionarily related proteins are finding increasing use as indicators of critical amino acid residues necessary for structural stability or involved in functional domains responsible for catalytic activities. In the past, a number of alignments have provided such information for the herpesviral thymidine kinases, for which three-dimensional structures are not yet available. We have sequenced the thymidine kinase gene of a canine herpesvirus, and with a multiple alignment have identified amino acids preferentially conserved in either of two taxons, the genera Varicellovirus and Simplexvirus, of the subfamily Alphaherpesvirinae. Since some regions of the thymidine kinases show otherwise elevated levels of substitutional tolerance, these conserved amino acids are candidates for critical residues which have become fixed through selection during the evolutionary divergence of these enzymes. Several pairs with distinctive patterns of distribution among the various viruses occur in or near highly conserved sequence motifs previously proposed to form the catalytic site, and we speculate that they may represent interacting, co-ordinately variable residues.

Cloning and characterization of the cDNAs encoding Na+ channel-specific toxins 1 and 2 of the scorpion Centruroides noxius Hoffmann.

Using a cDNA library prepared from venomous glands of the Mexican scorpion Centruroides noxius Hoffmann the genes that encode toxins 1 and 2 were identified, cloned and sequenced. In view of the proposed mechanism for processing the mature peptides coded by these two genes, the corresponding peptide-toxins were sequenced de novo. Mass spectrometric and 1H-NMR analyses of the C-terminal peptide produced by enzymatic digestion of both toxins indicated that the last residue is serine-amide. Sequence comparison revealed that these two genes have a similarity of 56% and 80% at the amino acid and nucleotide levels, respectively. Small corrections to the published primary structures were introduced: Cn toxin 1 has an extra serine residue at position 65 and the residue in position 60 is a proline, while the amino acids at positions 34 and 35 of Cn 2 are, respectively, tyrosine and glycine. Sequence comparison of toxins from the genus Centruroides suggests the presence of at least three classes of distinct peptides in these venoms.

Use of topically applied silver sulphadiazine plus cerium nitrate in major burns.

All patients hospitalized between May 1987 and June 1988 suffering from burns covering over 50 per cent of the body surface area were treated by topical application of a cream containing cerium nitrate (0.05 M) and silver sulphadiazine (0.03 M) (CN + SSD). Eleven patients were included in this series, with a mean age of 35 years (range 22-65), a mean total burn size of 78 per cent (range 50-96 per cent) and full skin thickness covering a mean of 48 per cent (range 10-91 per cent). Eight patients survived (73 per cent) (mean age 36 years; mean total burn surface 73 per cent; mean full skin thickness burn surface, 38 per cent). These results are far better than those obtained in our Unit where a survival rate of 34 per cent was obtained in a comparable series of patients treated before 1987. Sixty positive blood cultures were obtained, which included a large variety of organisms with a slight predominance of Staph. aureus, Candida albicans and Ps. aeruginosa. Wound cultures were positive in 72 per cent of swabs and showed a predominance of Ps. aeruginosa (59 per cent of all the strains isolated). Even if CN + SSD appears in this series not to be very efficient in preventing wound colonization and septic complications, it permitted a very high survival rate in the treated patients, taking into account the extreme severity of the injuries. This beneficial effect is probably the consequence of the protective action of the yellow-green eschar formed by CN + SSD.(ABSTRACT TRUNCATED AT 250 WORDS)

Exposure of in vitro-produced bovine embryos to foot-and-mouth disease virus.

The aim of this study was to investigate whether foot and mouth disease virus (FMDV) interacts with in vitro produced (IVP) bovine embryos. One milliliter of a suspension of FMDV (2 x 10(7) TCID50/mL) was added to several batches of these embryos 7 d after in vitro fertilization, by which time they had either developed to the morula/blastocyst stage (n = 256) or degenerated (n = 260). Six experiments were performed in which developed or degenerated batches of embryos were incubated with FMDV for periods of 1 h (3), 2 h (2) or 4h (1). After this, the embryos were washed 10 times according to the International Embryo Transfer Society (IETS), then pooled and ground up to form a suspension, and assayed on cell cultures for FMDV. The cell cultures were observed daily for cytopathic effects for 3 d post exposure. In addition to the cell culture method, the polymerase chain reaction (PCR) technique was used to assay for the presence of the virus in the washing fluids. Assays for FMDV were also conducted on the first and second wash and on the pooled sample constituting the eight, ninth and tenth wash. With the exception of the second wash from a batch of embryos exposed to FMDV for 2 h, all samples of the first and second wash produced FMDV cytopathic effects, but none occurred with the pooled samples of the 8th, 9th and 10th wash. FMDV was also isolated from all but 1 of the batches of embryos after 1 h of incubation, from 1 of 4 batches after 2 h of incubation and from all batches after 4 h incubation. By contrast, the presence of virus could not be demonstrated by PCR based on the technique used here. These results show that 7 d old IVP bovine embryos can retain FMDV after washing, unlike in vivo-derived embryos, which do not appear to carry risks of FMDV transmission when washed according to IETS recommendations. Stricter controls are, therefore, necessary when using IVP embryos from cattle in a non-FMD-free zone in domestic or international trade.

Identification of bluetongue virus serotype 2 (Corsican strain) by reverse-transcriptase PCR reaction analysis of segment 2 of the genome.

In October 2000, bluetongue virus was detected on the French island of Corsica. The disease was also reported in Sardinia, Calabria, Sicily and on the Spanish islands of Majorca and Minorca. This paper describes the use of molecular techniques for a rapid identification and serotype determination of serotype 2 of the virus. The nucleotide sequences of segments 2 and 7 of the genome of the Corsican strain were determined and its phylogenetic relationships are described.

[The shoulder-hand syndrome after stroke: clinical factors of severity and value of prognostic score of Perrigot]. / Algoneurodystrophie du membre supérieur de l'hémiplégique : facteurs cliniques de gravité et intérêt du score pronostique de Perrigot.

PURPOSE: The purposes of this study were to evaluate the prognostical factors of reflex sympathetic dystrophy in stroke patients in attempt to improve the Perrigot prognostical score. MATERIAL AND METHOD: This prospective study included 28 stroke patients with reflex sympathetic dystrophy. An initial clinical assessment including Perrigot score was made at the time of admission (before the end of the first month) and a second evaluation of reflex sympathetic dystrophy at the end of the third month. Patients were assessed using Motricity Index, Ashworth scale, de Bats grading (for glenohumeral alignment), Labrousse criteria (for reflex sympathetic dystrophy severity), and MADRS depression scale. Sensory deficit and unilateral neglect were noted. RESULTS: The length of stay in acute ward was 16 days. The Perrigot score was correlated with the reflex sympathetic dystrophy severity (r = 0.7, p < 0.0001). It predicted the result of therapy. A significant correlation was found between reflex sympathetic dystrophy severity and motor deficit (r = -0.591, p = 0.0007) and spasticity (p < 0.05). No relation was found with stroke side, unilateral neglect, depression or shoulder subluxation. It wasn't possible to improve the Perrigot prognostical score. CONCLUSION: Perrigot score predict reflex sympathetic dystrophy severity and the result of therapy. The shoulder subluxation which is not included in this score appears to be not predictive. Shoulder subluxation is simply a marker of a severe paresis.

[Microscopic extensions of head and neck squamous cell carcinomas: impact for clinical target volume definition]. / Approche anatomopathologique de l'extension microscopique des carcinomes épidermoïdes ORL : implications pour la définition du volume cible anatomoclinique.

PURPOSE: To assess microscopic extensions of head and neck squamous cell carcinomas aiming at a proposal for target volumes of radiation therapy. MATERIALS AND METHODS: Surgical specimens were prospectively analysed macroscopically and microscopically. Tumour borders were identified per macroscopic visual examination and inked on stained slides. Then microscopic implants (perineural or lymphatic involvement, or in situ carcinomas) were looked for with an optic microscope in the macroscopic healthy tissue surrounding the tumour. The maximal length from tumour border was correlated with the maximal length of macroscopically healthy tissues assessable. RESULTS: Twenty-one specimens were analysed and 12 were locally advanced tumours. Mean and median maximal microscopic extensions were 2.9 and 1.0mm (0-15mm), respectively. The 90th and 95th percentiles were 5 and 11mm, respectively. The ratio between healthy tissue length and maximal microscopic tumour extension was 10%. No correlation was found with tumour grade or volume. CONCLUSION: The presence of microscopic tumour was unlikely after 5mm from macroscopic tumour (≤5% of patients in this series) but should be assessed along with other histoclinical factors and particularities of tumour behaviour by anatomic site. A rigorous terminology should authorize a relevant appreciation of local risk of recurrence, particularly in adjuvant setting or for clinical target volume definition. Larger and more homogenous confirmatory series are needed.

Fetal thrombotic vasculopathy is associated with thromboembolic events and adverse perinatal outcome but not with neurologic complications: a retrospective cohort study of 54 cases with a 3-year follow-up of children.

OBJECTIVE: to test the hypothesis that placental fetal thrombotic vasculopathy (FTV) is associated with obstetric complications and predisposes the child to unfavorable outcomes. METHODS: 54 placentas with FTV lesions and 100 placentas without FTV lesions were collected over a 5-year period at the Croix-Rousse Pathology Department. Clinical findings including maternal, fetal, neonatal condition and pediatric outcome up to three years were collected for each case and control observation. The statistical analyses were assessed with Wald's chi-square derived from conditional logistic regression modeling. RESULTS: FTV was associated with a significantly higher frequency of obstetric complications: (pregnancy-induced hypertension (OR 3.620, CI 1.563-8.385), preeclampsia (OR 3.674, CI 1.500-8.998), emergency delivery procedures (OR 3.727, CI 1.477-9.403), cesarean sections (OR 2.684, CI 1.016-7.088)), poor fetal condition (intrauterine growth restriction (IUGR) (OR 5.440, CI 2.007-14.748), nonreassuring fetal heart tracing (OR 6.062, CI 2.280-16.115), difficulties in immediate ex utero adaptation (OR 3.416, CI 1.087-10.732)) and perinatal or early childhood demise (OR 3.043, CI 1.327-6.978). On pathological examination, FTV was associated with marginal cord insertion (OR 3.492, CI 1.350-9.035), cord stricture and hypercoiled cord (OR 3.936, CI 1.209-12.813). Thromboembolic events were significantly more frequent in cases with FTV (OR 2.154, CI 1.032-5.622). Neurological complications within the first 3 years of life were also more frequent in the FTV group compared to the control group, but this association was not statistically significant. CONCLUSIONS: FTV is associated with maternal complications, pathological findings in the placenta, especially gross cord abnormalities, IUGR, and poor perinatal or early childhood outcome. It may also predispose children to somatic thromboembolic events.

[Flexible laryngeal mask airway use during surgical burn management with head mobilisation: a feasibility study]. / Intérêt du masque laryngé renforcé au cours de la chirurgie réparatrice chez les patients brûlés nécessitant une mobilisation de la tête : étude de faisabilité.

OBJECTIVE: To evaluate the feasibility and reliability of the flexible laryngeal mask airway (LMA flexible) use during scalp skin harvesting for surgical reparation of burn sequella. STUDY DESIGN: Observational prospective descriptive study. PATIENTS AND METHODS: Following local ethic committee approval, 26 patients were included in the study during their preanaesthesia visit. The general anaesthesia induction of each patient was followed by the insertion of a LMA flexible. The number of attempts required to insert the mask and the procedure were documented. The oropharyngeal leak pressure, expired tidal volume and end tidal CO(2) were recorded in five different head positions (neutral, hyperflexion, hyperextension, right and left rotation) at the start and end of surgical procedure. In all ten study periods of 2-3 min each were evaluated. RESULTS: The airway device was inserted easily in all patients. While similar in four of the five head positions (neutral: 27.9+/-8.1 cmH(2)O, hyperextension, left and right rotation), the oropharyngeal leak pressure was significantly higher in the hyperflexion position (33.3+/-7.3 cmH(2)O). The end tidal volume was stable in all positions except hyperflexion (419+/-114 ml). While this value was significantly lower than the 471+/-68 ml recorded in the neutral position, it remained greater than 7 ml/kg. No significant change was observed for end tidal CO(2) for the ten study periods. CONCLUSION: The use of LMA flexible during surgical burn repair procedures, including head mobilisation for the harvesting of scalp skin grafts is feasible.

[Testicular choriocarcinoma presenting as cutaneous metastasis. A case report and review of the literature]. / Les métastases cutanées révélatrices des choriocarcinomes: revue de la littérature. A propos d'une localisation nasale d'origine testiculaire.

Choriocarcinoma are germinal tumors from testicular cells in men or foetal trophoblast in women. Cutaneous metastasis are very rare. The authors report a case of angioma-like tumor in a 22-year-old man which was a cutaneous metastasis of a testicular carcinoma. Diagnosis was of course histologic. Testicular echography showed an intra testicular tumor, pulmonary and abdominal CT-scan showed multiple metastases. Orchidectomy and retroperitoneal lymphadenectomy were performed before a general chemotherapy. Patient died 14 months after diagnosis. Only 11 cases of cutaneous metastasis of choriocarcinoma were found in the world literature (7 men and 4 women). All cases showed diagnosis trap for plastic surgeon.

Partial DNA cloning and sequencing of a canine parvovirus vaccine strain: application of nucleic acid hybridization to the diagnosis of canine parvovirus disease.

The cloning and sequencing of an Eco RI-PstI fragment derived from the replicative form of a canine parvovirus (CPV) vaccine strain are reported. The variability of the 5' end of NS 1 protein gene in the genome is confirmed by comparison with previously determined DNA sequences. A 15 nucleotide deletion was also observed in this vaccine strain. In order to improve CPV diagnosis, radioactively labelled RNA or DNA and biotin labelled DNA obtained by random priming of the recombinant plasmid were used as probes mainly on gut or stool samples from naturally infected dogs. Results of filter hybridization correlated well with histopathological diagnosis of parvovirus infection and with hemagglutination tests performed on dog faeces. We propose that nucleic acid hybridization may be an alternative diagnostic method to ascertain the presence of CPV, especially in frozen samples.
