A new nematode, <Emphasis Type="Italic">Pongobius hugoti</Emphasis> gen. et sp. n. from the orangutan <Emphasis Type="Italic">Pongo abelii</Emphasis> (Primates: Hominidae)

Summary Light and scanning electron microscopical examination and molecular analysis of pinworm samples collected from the Sumatran orangutan (Pongo abelii) from Sumatra (Indonesia) revealed the presence of a new taxon, Pongobius hugoti gen. et sp. n. (Oxyuridae: Enterobiinae). The monotypic genus Pongobius is characterised by the presence of a triangular mouth, three rounded teeth and three chisel-like inner teeth in the buccal cavity, an oesophagus with a long pharyngeal part, corpus posteriorly slightly enlarged and continuing as a pyriform bulb, isthmus absent. These features differentiate P. hugoti from all members of the subfamily Enterobiinae. The male has a long caudal appendix (> 50% of total tail length). Molecular analysis of the new taxon is presented for more precise identification.

Lichen sclerosus in childhood

Lichen sclerosus in childhood involves predominantly the genital area, often with purpura and erosions, which raises concerns of sexual abuse. Potent topical corticosteroids give a good clinical response over several months, although maintenance with weaker formulations is usually required. The long-term prognosis remains uncertain.

Organisation anatomique et physiologique des activités motrices de la moelle épinière

Résumé La moelle épinière utilise deux grandes modalités fonctionnelles: l'activité réflexe et l'activité programmée.L'activité réflexe constitute la modalité la plus anciennement connue, elle englobe de nombreux arcs réflexes imprégnés de finalités fort diverses. Ainsi le réflexe myotatique, arc monosynaptique le plus simple, maintient et protège le tonus musculaire; les réflexes à point de départ cutané, polysynaptiques, impliquant des réseaux interneuronaux, extériorisent des réponses motrices de défense et de protection indiquant déjà une compétence plus intégrative.L'activité programmée médullaire est supportée par des circuits neuronaux assez solidement fixés. Cette organisation fonctionnelle produit des séquences motrices correctement agencées dans l'espace et dans le temps (locomotion, miction, défécation, réflexes sexuels).Aces deux modalités basales viennent se superposer les influences supra-spinales à capacité exécutoire. Ces signaux, canalisés vers la voie finale commune, agissent, dans une faible part, directement sur les motoneurones spinaux et, en effet, dans une très large mesure, ils utilisent les circuits interneuronaux et modulent ou déclenchent réflexes et programmes médullaires engendrant ainsi une activité cinétique cohérente.     

Growth of dendrites in the optic tectum of the chick embryo following destruction of the eye primordium.

The consequences of depriving the optic tectum of axons from the contralateral eye have been studied in Golgi-impregnated brains from a staged series of chick embryos. Following enucleation at 2–5 days of age, measurements of dendritic length and the numbers of branches at all orders for three cell types were performed with an automated three-dimensional tracking system at various survival times. Dendritic lengths and the number of middle order branches of neurons from control animals, aged 12–14 days (stages 38–40), are greater than those from non-innervated embryos of the same ages. However, by Day 18 (stage 44), no significant differences in length or branching are seen between neurons from control and experimental embryos. Observations of these neurons revealed qualitative differences between experimental and control embryos. Growth cones, varicosities and filopodia, indicators of dendritic differentiation, are more commonly associated with neurons from control Day 12 and 14 embryos, than operated embryos of the same stages. However, at Days 16 and 18 these growth characteristics are more usually seen on neurons from deafferented embryos than from controls.The deleterious effects observed in experimental animals between Days 12 and 14 are presumably caused by the absence of optic fibers. The eventual growth during late embryogenesis, of the cells deprived of optic input, may reflect a trophic influence not acting in the earlier period.     

The goldfish optic tectum: a Golgi study.

The detailed morphology of neurons in the optic tectum of the common goldfish, Carassius auratus, was reinvestigated using rapid Golgi and Golgi-Cox methods. Neurons were classified initially on the basis of the orientation of the primary dendritic processes within the tectum: vertical, horizontal and non-oriented. These 3 groups were subdivided according to the shape of the soma and the axonal and dendritic configurations.The cell types observed in the present study were compared with those reported in earlier analyses of the goldfish optic tectum. Numerous differences, primarily of soma location and axonal origin and pathway for each cell type, were found. The structure of the goldfish optic tectum appears to be quite similar to the tectum of other teleosts.     

Vulvovaginal candidiasis among symptomatic women of childbearing age attended at a Medical Analysis Laboratory in Franceville,Gabon

BackgroundVulvovaginal candidiasis (VVC) is one of the most common lower genital tract infections in women; this unpleasant and extremely embarrassing pathology is one of the main reasons for gynaecological consultation. In Gabon, the prevalence of VVC remains poorly described even though VVC is known to be the leading gynaecological condition in several countries. This retrospective cross-sectional study sought to assess the prevalence of VVC among symptomatic women in southeastern Gabon.MethodsClinical samples were collected from patients suspected to have VVC during a 2-year period (from January 2016 to December 2017). Gram staining of vaginal smears provided indications of vaginal flora and confirmed the presence of yeast. Sabouraud-chloramphenicol and chromID Candida media were used to isolate yeast, and species identification was performed using morphological tests and the Vitek 2 Compact automated system.ResultsFor the 873 patients included in this study, the prevalence of VVC was 28.52%. Eleven Candida species were identified, with greater representation of Candida albicans (82.73%) than of Non C. albicans candida (NCAC) (17.27%), which were distributed as follows: Candida famata (4.02%), Candida spp. (3.61%), Candida rugosa (3.21%), Candida lipolytica (1.61%), Candida parapsilosis (1.61%), Candida glabrata (1.21%), Candida tropicalis (0.80%), Candida krusei (0.40%), Candida dubliniensis (0.40%), and Candida sphaerica (0.40%).ConclusionThis study offers the first estimation of VVC among Gabonese women in childbearing age with the symptoms. It showed that VVC is very common in Gabon. C. albicans as the most commonly represented species.
