Mutations in the cdc10 start gene of Schizosaccharomyces pombe implicate the region of homology between cdc10 and SWI6 as important for p85cdc10 function.

The cdc10 gene of the fission yeast Schizosaccharomyces pombe is required for traverse of start and commitment to the mitotic cell division cycle rather than other fates. The product of the gene, p85cdc10, is a component of a factor that is thought to be involved in regulating the transcription of genes that are required for DNA synthesis. In order to define regions of the p85cdc10 protein that are important for its function a fine structure genetic map of the cdc10 gene was derived and the sequences of 13 cdc10ts mutants determined. The 13 mutants tested define eight alleles. Eleven of the mutants are located in the region that contains the two copies of the cdc10/SWI6 repeat motif, implicating it as important for p85cdc10 function.

Ophtalmologie. Rétinopathie diabétique: nouvelles possibilités thérapeutiques [Diabetic retinopathy: new therapeutic possibilities].

La rétinopathie diabétique touche un nombre croissant de personnes, soit quatre millions en Europe, ce chiffre va probablement doubler d'ici 2030. Si l'on considère que 25-30% de ces patients sont atteints de rétinopathie diabétique, un dépistage et un traitement précoce permettent d'éviter les complications oculaires sévères telles que l'oedème maculaire cystoïde où la rétinopathie diabétique proliférative. Un résumé des dernières données de la littérature ophtalmologique est présenté en insistant sur le rôle de l'anti-VEGF (vascular endothelial growth factor) et des implants intravitréens de corticostéroïdes pour une pathologie oculaire récemment classée dans les pathologies inflammatoires. Diabetic retinopathy affects an increasing number of persons, about 4 millions in Europe, a number that will probably double until 2030. If we consider that 25-30% of patients are affected by diabetic retinopathy, an ophthalmologic screening and early therapy will allow a better visual prognosis and avoid severe ocular complications such as diabetic macular edema and proliferative diabetic retinopathy. A summary of current ophthalmologic literature was performed and was focused on the role of anti-VEGF (vascular endothelial growth factor) therapies and intraocular drug delivery of corticosteroids in a pathology that was recently classified in inflammatory pathologies.

Mycoplasma hominis in mid-trimester amniotic fluid : relation to pregnangy outcome

RESUME Introduction : Les naissances prématurées compliquent 6-10 % des grossesses dans les pays industrialisés et contribuent de façon notable aux taux de mortalité périnatale et de morbidité néonatale. Il a été démontré que la colonisation bactérienne du liquide amniotique joue un rôle dans l'étiologie des accouchements prématurés spontanés et des ruptures prématurées des membranes. Le but de ce travail était d'évaluer la présence de Mycoplasma hominis dans le liquide amniotique prélevé au 2eme trimestre de grossesse chez des patientes asymptomatiques et de déterminer son association avec une issue défavorable de la grossesse. Matériels et méthodes : Les échantillons de liquide amniotique de 456 patientes ayant subi une amniocentèse trans-abdominale entre les 15eme et I7eme semaines de grossesse pour diverses indications ont été testés par PCR (Polymerase Chain Reaction) afin d'identifier Mycoplasma hominis. Les produits ainsi amplifiés étaient ensuite détectés par ELISA (Enzyme-Linked Immunosorbent Assay). Les données cliniques étaient obtenues après l'accouchement. Résultats : Mycoplasma hominis a été identifié dans 29 (6,4%) des échantillons de liquide amniotique. Le taux de menace d'accouchement prématuré chez les patientes positives pour Mycoplasma hominis (14,3%) était plus élevé que chez les patientes négatives (3,3 %) (p=0,01). De même, les naissances prématurées spontanées avec membranes intactes étaient plus fréquentes chez les patientes positives (10,7%) que chez les patientes négatives (1,9 %) (p=0,02). Le taux de menace d'accouchement prématuré lors d'une grossesse antérieure était plus de trois fois plus élevé chez les patientes positives, cependant ce résultat n'était pas statistiquement significatif. Finalement, la présence du mycoplasme n'était pas corrélée à la gestose, au retard de croissance intra-utérin ou aux anomalies chromosomiques foetales. Conclusions : Les résultats montrent que la présence de Mycoplasma hominis dans le liquide amniotique prélevé entre les 15eme et I7eme semaines d' aménorrhée chez des patientes asymptomatiques est associée à un taux plus élevé de menace d'accouchement prématuré et de naissances prématurées spontanées. La détection de ce microorganisme au 2eme trimestre de la grossesse peut donc identifier les patientes à risque de menace d'accouchement et de naissance prématurées. Abstract Objective: The relationship between detection of Mycoplasma hominis in mid-trimester amniotic fluid and subsequent pregnancy outcome was investigated. Study design: Amniotic fluids from 456 women of European background who underwent a transabdominal amniocentesis at weeks 15-17 of pregnancy were tested for M. hominis by polymerase chain reaction (PCR). The amplicons were hybridized to an internal probe and detected by ELISA. Pregnancy outcomes and clinical data were subsequently obtained. Results: M. hominis were identified in 29 (6.4%) of the amniotic fluids. The rate of preterm labor in women positive for M. hominis (14.3%) was higher than in the negative women (3.3%) (p = 0.01). Similarly, a spontaneous preterm birth with intact membranes occurred in 10.7% of the M. hominis-posltive women as opposed to only 1.9% of the negative women (p = 0.02). The presence of this mycoplasma was not correlated with fetal chromosomal aberrations, intrauterine growth restriction or preeclampsia. Conclusions: Detection of M. hominis in second-trimester amniotic fluids can identify women at increased risk for subsequent preterm labor and delivery.

Repeat Gamma Knife surgery for recurrent trigeminal neuralgia: long-term outcomes and systematic review.

Object The purpose of this study was to establish the safety and efficacy of repeat Gamma Knife surgery (GKS) for recurrent trigeminal neuralgia (TN). Methods Using the prospective database of TN patients treated with GKS in Timone University Hospital (Marseille, France), data were analyzed for 737 patients undergoing GKS for TN Type 1 from July 1992 to November 2010. Among the 497 patients with initial pain cessation, 34.4% (157/456 with ≥ 1-year follow-up) experienced at least 1 recurrence. Thirteen patients (1.8%) were considered for a second GKS, proposed only if the patients had good and prolonged initial pain cessation after the first GKS, with no other treatment alternative at the moment of recurrence. As for the first GKS, a single 4-mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.6 mm (range 4-14 mm) anterior to the emergence of the nerve (retrogasserian target). A median maximum dose of 90 Gy (range 70-90 Gy) was delivered. Data for 9 patients with at least 1-year followup were analyzed. A systematic review of literature was also performed, and results are compared with those of the Marseille study. Results The median time to retreatment in the Marseille study was 72 months (range 12-125 months) and in the literature it was 17 months (range 3-146 months). In the Marseille study, the median follow-up period was 33.9 months (range 12-96 months), and 8 of 9 patients (88.9%) had initial pain cessation with a median of 6.5 days (range 1-180 days). The actuarial rate for new hypesthesia was 33.3% at 6 months and 50% at 1 year, which remained stable for 7 years. The actuarial probabilities of maintaining pain relief without medication at 6 months and 1 year were 100% and 75%, respectively, and remained stable for 7 years. The systematic review analyzed 20 peer-reviewed studies reporting outcomes for repeat GKS for recurrent TN, with a total of 626 patients. Both the selection of the cases for retreatment and the way of reporting outcomes vary widely among studies, with a median rate for initial pain cessation of 88% (range 60%-100%) and for new hypesthesia of 33% (range 11%-80%). Conclusions Results from the Marseille study raise the question of surgical alternatives after failed GKS for TN. The rates of initial pain cessation and recurrence seem comparable to, or even better than, those of the first GKS, according to different studies, but toxicity is much higher, both in the Marseille study and in the published data. Neither the Marseille study data nor literature data answer the 3 cardinal questions regarding repeat radiosurgery in recurrent TN: which patients to retreat, which target is optimal, and which dose to use.

Use of antibiotics in pediatric intensive care and potential savings.

OBJECTIVE: Minimizing unwarranted prescription of antibiotics remains an important objective. Because of the heterogeneity between units regarding patient mix and other characteristics, site-specific targets for reduction must be identified. Here we present a model to address the issue by means of an observational cohort study. SETTING: A tertiary, multidisciplinary, neonatal, and pediatric intensive care unit of a university teaching hospital. PATIENTS: All newborns and children present in the unit (n = 456) between September 1998 and March 1999. Reasons for admission included postoperative care after cardiac surgery, major neonatal or pediatric surgery, severe trauma, and medical conditions requiring critical care. METHODS: Daily recording of antibiotics given and of indications for initiation. After discontinuation, each treatment episode was assessed as to the presence or absence of infection. RESULTS: Of the 456 patients 258 (56.6%) received systemic antibiotics, amounting to 1815 exposure days (54.6%) during 3322 hospitalization days. Of these, 512 (28%) were prescribed as prophylaxis and 1303 for suspected infection. Treatment for suspected ventilator-associated pneumonia accounted for 616 (47%) of 1303 treatment days and suspected sepsis for 255 days (20%). Patients were classified as having no infection or viral infection during 552 (40%) treatment days. The average weekly exposure rate in the unit varied considerably during the 29-week study period (range: 40-77/100 hospitalization days). Patient characteristics did not explain this variation. CONCLUSION: In this unit the largest reduction in antibiotic treatment would result from measures assisting suspected ventilator-associated pneumonia to be ruled out and from curtailing extended prophylaxis.

Presence of Triatominae (Hemiptera, Reduviidae) and Risk of Transmission of Chagas Disease in Colima, México

With the purpose of evaluating the risk of transmission of the Chagas disease in the State of Colima, México, an entomological survey was performed to obtain triatominae and the rate of infection by Trypanosoma cruzi determined by examination of its dejections. Two hundred eighteen houses located in 16 villages were sampled. In each house the intradomestic and peridomestic habitats were examined by the man-hour-house method, sensor boxes and mouse-baited traps. Also, 12 silvatic places were explored around the same areas using the same techniques as the ones sampled. In total, 456 specimens were captured, of which 139 correspond to Triatoma phyllosoma pallidipennis; 80 to T. p. longipennis; one specimen of T. dimidiata and 236 nymphs of Triatoma sp. Two hundred ninety seven insects were captured in the intradomestic habitat, 132 in the peridomestic and 26 in the silvatic. The index of positive houses was 27%, located in the central area of the state. The rate of natural infection with T. cruzi showed 25.6%. This results confirmed the presence of two important vectors of the Chagas disease in Colima. Its preference for the domestic habitat and its high levels of natural infection with T. cruzi suggested the existence of a significant risk for its transmission in this area of the country.

African migrants in Asian and European football: hopes and realities

This paper analyses the integration of Africa in the global labour market of football through the study of players' migrations to Asia and Europe. The presence of African footballers in the latter continent is analysed via a statistical survey carried out in September and October 2008 on a sample of 456 top division clubs in 30 European countries. The article emphasizes that the aspirations placed on football by male African youth, as a means of upward social mobility, are often too high when compared to the harsh realities of a transfer market based on commercial logics, which each year push many footballers away from the professional game.

Nosology and classification of genetic skeletal disorders: 2010 revision.

Genetic disorders involving the skeletal system arise through disturbances in the complex processes of skeletal development, growth and homeostasis and remain a diagnostic challenge because of their variety. The Nosology and Classification of Genetic Skeletal Disorders provides an overview of recognized diagnostic entities and groups them by clinical and radiographic features and molecular pathogenesis. The aim is to provide the Genetics, Pediatrics and Radiology community with a list of recognized genetic skeletal disorders that can be of help in the diagnosis of individual cases, in the delineation of novel disorders, and in building bridges between clinicians and scientists interested in skeletal biology. In the 2010 revision, 456 conditions were included and placed in 40 groups defined by molecular, biochemical, and/or radiographic criteria. Of these conditions, 316 were associated with mutations in one or more of 226 different genes, ranging from common, recurrent mutations to "private" found in single families or individuals. Thus, the Nosology is a hybrid between a list of clinically defined disorders, waiting for molecular clarification, and an annotated database documenting the phenotypic spectrum produced by mutations in a given gene. The Nosology should be useful for the diagnosis of patients with genetic skeletal diseases, particularly in view of the information flood expected with the novel sequencing technologies; in the delineation of clinical entities and novel disorders, by providing an overview of established nosologic entities; and for scientists looking for the clinical correlates of genes, proteins and pathways involved in skeletal biology. © 2011 Wiley-Liss, Inc.

Anatomic and functional outcome after 23-gauge sutureless transconjunctival vitrectomy, peeling and intravitreal triamcinolone for idiopathic macular epiretinal membranes

Purpose:To report the functional, anatomic outcome and safety profile of 23-gauge pars plana vitrectomy (PPV) combined with peeling and intravitreal injection of triamcinolone acetonide (TA) in eyes with idiopathic epiretinal membranes (ERM). Methods:Retrospective, nonrandomized study of consecutive patients who underwent 23-gauge transconjunctival sutureless PPV with subsequent membrane peeling and intravitreal TA injection for an idiopathic ERM. All patients were operated between February 2007 and February 2008 at the Jules Gonin University Eye Hospital. The minimum follow-up was 6-months. Results:Thirty-nine eyes of 39 patients were included. The mean follow-up was 7 months (SD: 2.2, range: 6-15 months). Twenty-two (56%) eyes were pseudophakic and 17 (44%) were phakic at the time of surgery. Mean preoperative intraocular pressure (IOP) was 14 mmHg (SD: 3.5). At the final follow-up mean IOP was 14.5 (SD: 2.7) that did not differ significantly from the IOP at baseline (P: 0.14- 2-tailed t test). Five patients (13%) needed temporary topical anti-glaucoma treatment.Mean preoperative BCVA was 0.28 decimal equivalent (logMAR 0.54, SD: 0.2, range: 1.0 - 0.2). and improved significantly (P <0.0001, 2-tailed t test) to a mean of 0.6 decimal equivalent (logMAR 0.22, SD: 0.16, range: 0.6 - 0) at the final follow-up. The visual acuity improved by a mean of 3.2 lines (SD 2.1, range 0- 8). Twenty-nine patients (74%) demonstrated a gain of 3 or more lines.Mean central macular thickness (CMT) was 456 µm (SD: 77) at the baseline that reduced significantly (P <0.0001, 2-tailed t test) at the final follow-up to 327µm (SD: 79). Average CMT reduction was 131µm (SD: 77, range: 36- 380 µm). A subgroup analysis of 15 selected cases that had CMT measurement 1 week after surgery demonstrated that 84% of the total final reduction in CMT occurred during the first week. Conclusions:23-gauge sutureless transconjunctival vitrectomy with the concomitant administration of intravitreal TA is a safe and effective technique for the treatment of idiopathic ERM and may speed up anatomical recovery.
