Fine Needle Aspiration Cytology In Parotid Lumps, A Zafar, M Shafi, S H. Hassan, S Malik

Section of Otolaryngology, Head & Neck Surgery

Over a period of two years, Fine Needle Aspiration Cytology (FNAC) was performed on 33 patients presenting with a parotid lump. Five patients were excluded as they were treated medically after FNAC report. The FNAC results of 28 cases were compared with histopathological diagnoses of surgically resected specimens. There were 8 true positive, 17 true negative, 1 false positive and 2 false negative cases. Sensitivity was 80%, specificity 94.4% and diagnostic accuracy 89.3%. FNAC is a simple quick, accurate and virtually complications free investigative modality. It is also helpful adjunct to assess preoperatively the suitability and extent of the surgical …

Identification, Localization, And Characterization Of Sodium/Hydrogen Exchanger Isoforms 1 And 3 In The Gerbil Cochlea, Brian R. Bond

MUSC Theses and Dissertations

Mongolian gerbils were used in an investigation into the expression of cochlear sodium/hydrogen (NHE) exchanger isoforms 1,2,3 and 4. NHE 1-4 gene products were identified in the gerbil inner ear by reverse-transcription polymerase chain reaction (RT-PCR). The distribution of NHE-1 and 3 subsequently was mapped in the adult gerbil inner ear using isoform-specific polyclonal antibodies generated against rat antigens. Changes in the cellular expression level of NHE-1 protein in response to treatment with dexamethasone or NH4 CI-induced acidification were then assessed by semiquantitative immunohistochemical analysis. Cochlear cDNA was amplified by the polymerase chain reaction (PCR) using NHE isoform-specific primers based …
