Multifocal periapical cement dysplasia in Ehlers-Danlos Typ VIII combined with leukoencephalopathy in de novo-mutation of c.890G>A, G297D [pEDS]

Periodontal Ehlers-Danlos syndrome type VIII (pEDS) is rare and caused by mutation in complement 1 subunit. Lack of attached gingiva, pretibial plaques, joint mobility, skin fragility, and easy bruising consolidate the diagnosis. We describe a case of de novo-mutation of pEDS with generalized periapical cemento dysplasia (PCD) and leukoencephalopathy.

Wet Dark Fluid Cosmological Model in Barber Self-Creation Theory of Gravitation

This paper investigates a Bianchi type VIII cosmological model with wet dark fluid in Barber self-creation theory of gravitation. To get the determinate model of the Universe, we have assumed the relationship between metric coefficients R and S. Also, the behavior of the model in the radiation Universe and the physical implications of the model are discussed in detail.

Differential expression of collagen type VIII alpha 1 chain in human epithelial ovarian cancer.

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding collagen type VIII alpha 1 chain, COL8A1, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. COL8A1 expression was significantly higher in high-grade serous ovarian tumors relative to normal fallopian tube. COL8A1 expression correlated with overall survival in patients with ovarian cancer. These data indicate that expression of COL8A1 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. COL8A1 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

Molecular Epidemiology and Antifungal Susceptibility of Trichophyton Isolates in Greece: Emergence of Terbinafine-Resistant Trichophytonmentagrophytes Type VIII Locally and Globally

Trichophyton isolates with reduced susceptibility to antifungals are now increasingly reported worldwide. We therefore studied the molecular epidemiology and the in vitro antifungal susceptibility patterns of Greek Trichophyton isolates over the last 10 years with the newly released EUCAST reference method for dermatophytes. Literature was reviewed to assess the global burden of antifungal resistance in Trichophyton spp. The in vitro susceptibility of 112 Trichophyton spp. molecularly identified clinical isolates (70 T. rubrum, 24 T. mentagrophytes, 12 T. interdigitale and 6 T. tonsurans) was tested against terbinafine, itraconazole, voriconazole and amorolfine (EUCAST E.DEF 11.0). Isolates were genotyped based on the internal transcribed spacer (ITS) sequences and the target gene squalene epoxidase (SQLE) was sequenced for isolates with reduced susceptibility to terbinafine. All T. rubrum, T. interdigitale and T. tonsurans isolates were classified as wild-type (WT) to all antifungals, whereas 9/24 (37.5%) T. mentagrophytes strains displayed elevated terbinafine MICs (0.25–8 mg/L) but not to azoles and amorolfine. All T. interdigitale isolates belonged to ITS Type II, while T. mentagrophytes isolates belonged to ITS Type III* (n = 11), VIII (n = 9) and VII (n = 4). All non-WT T. mentagrophytes isolates belonged to Indian Genotype VIII and harbored Leu393Ser (n = 5) and Phe397Leu (n = 4) SQLE mutations. Terbinafine resistance rates ranged globally from 0–44% for T. rubrum and 0–76% for T. interdigitale/T. mentagrophytes with strong endemicity. High incidence (37.5%) of terbinafine non-WT T. mentagrophytes isolates (all belonging to ITS Type VIII) without cross-resistance to other antifungals was found for the first time in Greece. This finding must alarm for susceptibility testing of dermatophytes at a local scale particularly in non-responding dermatophytoses.
