background: central nervous system (cns) tumors have accounted for approximately one fourth of all pediatric malignancies. cns tumors have been the most common solid malignancies among the children. in this study, we have evaluated survival and prognostic factors in children with non-brain stem astrocytoma. methods: children with non-brain stem astrocytoma, referring to radiation oncology cente...

non hodgkin lymphomas (nhl) are nodal or extra nodal monoclonal infiltrations by malignant lymphoid cells (b lymphocytes in 80% of cases), which are distinguished as indolent or aggressive forms. according to the heterogeneity of lymphoid cells and their ubiquitous anatomical distribution, these disorders can develop in any organ and have very heterogeneous clinical expressions, but they are us...

background: onychomycosis results from invasion of the nail plate by dermatophytes, yeasts or mould species of fungi. the objective was to determine the etiological agents of onychomycosis. methods: a total of 549 patients clinically suspected of onychomycosis were examined for causative fungal agents. both di­rect microscopy and the cultures of the nail material were performed to identify the ...

background cutaneous leishmaniasis is the most common form of leishmaniasis caused by flagellate protozoa of the genus leishmania transmitted by sand fly bites. old world leishmaniasis is endemic in the mediterranean sea and the neighbouring countries. we believe, that this case is interesting by the fact that we had a very rear disease case that can be observed in nonendemic area. we present a...

mutations in the gjb2 gene at the dfnb1 locus on chromosome 13q12 are associated with autosomal recessive non syndromic hearing loss (arnshl) in many populations. a single mutation, at position 35 (35delg) accounts for approximately 30-63% of mutations in white populations with a carrier frequency of 1.5-2.5% in most european, north american and mediterranean populations. in this study we have ...

despite recent innovations in the laboratory diagnosis of bacterial from nonbacterial meningitis, solid data-necessary for early determination of bacterial meningitis (bm) before organism growth in the culture medium-are missing. therefore cerebrospinal fluid (csf) lactate levels were evaluated as a possible means of differentiating the two clinical entities. this was a retrospective study. pat...

‎this paper considers a non-local initial-boundary value problem containing a first order partial differential equation with variable coefficients‎. ‎at first‎, ‎the non-self-adjoint spectral problem is derived‎. ‎then its adjoint problem is calculated‎. ‎after that‎, ‎for the adjoint problem the associated eigenvalues and the subsequent eigenfunctions are determined‎. ‎finally the convergence ...

objective(s):non-alcoholic steatohepatitis (nash), is an important component of non-alcoholic fatty liver disease (nafld) spectrum, which progresses to the end stage liver disease, if not diagnosed and treated properly. the disproportionate production of pro- and anti-inflammatory adipokines secreted from fat contributes to the pathogenesis of nash. in this study, the comparative effect of piog...

background : there are only a few reports that exist regarding primary non-hodgkin lymphoma of the genital tract. in this article, one case of primary b-cell type non-hodgkin lymphoma (nhl) of the cervix is presented. case history: a 45 year-old woman presented bloody vaginal  discharge. upon vaginal examination, the cervix was found to be enlarged. cervical biopsy revealed b-cell type non-hodg...
