The relationship between T-cell infiltration in biopsy proven acute T-cell mediated rejection with allograft function and response to therapy: A retrospective study.

Aim: To evaluate the degree of CD3, CD20, Th17, and Tregs infiltration in kidney biopsy of the patients with acute cellular rejection and the possible relation with graft outcome.

Materials And Methods: In this retrospective study, fifty patients with Acute T Cell-Mediated Rejection (ATCMR) were enrolled. Previous and one year clinical follow-up data were collected.

The histologic features of intratubular germ cell neoplasia and its correlation with tumor behavior.

Purpose: To assess the prevalence of intratubular germ cell neoplasia (ITGCN) in patients with concurrent testis tumor and its correlation with histologic features and serum tumor markers.

Materials And Methods: From 2003 to 2015, 179 patients underwent radical orchiectomy due to testicular mass. Tissue specimens were evaluated by an expert uro-pathologist using immunohistochemistry (IHC) staining, in addition to light microscopy, to identify presence of ITGCN.

Genetic profiling of Klebsiella pneumoniae: comparison of pulsed field gel electrophoresis and random amplified polymorphic DNA.

In this study, the discriminatory power of pulsed field gel electrophoresis (PFGE) and random amplified polymorphic DNA (RAPD) methods for subtyping of 54 clinical isolates of Klebsiella pneumoniae were compared. All isolates were typeable by RAPD, while 3.6% of them were not typeable by PFGE.

Clinicopathological study of lacrimal sac specimens obtained during DCR.

Purpose: To determine the histopathologic characteristics of lacrimal sac specimens in adult patients undergoing external dacryocystorhinostomy (DCR) for acquired nasolacrimal duct obstruction.

Methods: A total of 471 lacrimal sac biopsies were obtained from 449 patients undergoing external DCR for symptoms or signs of acquired nasolacrimal duct obstruction and examined histopathologically.

Results: A total of 449 subjects including 283 (63%) female and 166 (37%) male subjects with mean age of 50.

Direct detection of Pseudomonas aeruginosa from patients with healthcare associated pneumonia by real time PCR.

Using oprL sequences, a TaqMan real time PCR was developed and used for quantitative detection of Pseudomonas aeruginosa from 99 broncoalveolar lavage and 11 sputum specimens collected from patients with health care associated pneumonia. All specimens were cultured on appropriate media to isolate bacteria. Twenty five specimens were positive by both methods.

Distribution of bla(TEM), bla(SHV), bla(CTX-M) genes among clinical isolates of Klebsiella pneumoniae at Labbafinejad Hospital, Tehran, Iran.

Extended-spectrum beta-lactamase (ESBL)-producing isolates of Klebsiella pneumoniae have been increasingly recognized in the hospital settings in Iran as well as throughout the world. The aim of this study was to detect and determine the genes encoding the ESBLs including bla(TEM), bla(SHV), and bla(CTX-M) groups among the K. pneumoniae isolates at Labbafinejad Hospital by polymerase chain reaction (PCR) and characterize them by direct sequencing of PCR products.
