Histopathological study of the catheterized fallopian tube-evidence of epithelial damage

The objective of this work was to investigate whether transcervical Fallopian tube catheterization with currently used catheters have a traumatic effect on tubal mucosa. A total of five hysterectomy specimens removed for nontubal pathology were included. In each case one tube was cannulated and the other was taken as a control. Serial sections were cut from intramural and isthmic portions and studied histologically for the presence of mucosal damage. The results showed that in all five cases there was a partial or complete detachment of tubal epithelium as compared with the control side. The injury was less marked in the isthmic portions. It was concluded that Fallopian tube cannulation with the currently used catheters have a traumatic effect on the tubal epithelium in the intramural and isthmic portions

Cytological study of bilharzial and non bilharzial urinay bladder carcinoma

One hundred cases presenting to the Urology Department, Tanta University Hospital were examined for the presence of bladder carcinoma. Cytological smears were examined after staining with Papanicolaou stain, as well as hematoxylene and eosin. Cystoscopic biopsies were also taken for histological evaluation. The accuracy of urine cytology was found to be proportional to the degree of tumor anaplasia. In bilharzial bladder carcinoma, urine cytology was accurate in 76% of cases while its accuracy was 65% in non-bilharzial cases. In squamous cell carcinoma, urine cytology was accurate in 69.4%, while in transitional cell carcinoma its accuracy was 77.4%. In adenocarcinoma, two cases out of three were diagnosed cytologically
