Cystic echinococcosis (CE) is a worldwide zoonotic helminthic disease caused by the larval stage of Echinococcus granulosus. The infection is particularly important in terms of economic and medico-veterinary aspects in endemic areas including Iran. Considering the possibility of organ-tropism in E. granulosus strains, the present study was aimed to identify the genotypes of E. granulosus in different organs involved in patients, undergone surgery in Baqiyatallah Hospital, Tehran, Iran from 2005-2015.

Overall, 29 formalin-fixed paraffin-embedded tissues (FFPT) from patients with histologically confirmed CE including liver (N: 14) lungs (N: 6) abdomen (N: 2), pancreas (N: 2) and each of spleen, gallbladder and, muscles (N: 1) plus unknown organs (N: 2) were used and genetically characterized using polymerase chain reaction, followed by partial sequencing of mitochondrial cytochrome c oxidase gene subunit 1(cox1) and analyzed.

Nineteen out of 29 isolates including liver (N: 6) lungs (N: 4) abdomen (N: 2), pancreas (N: 2) and each of spleen, gallbladder, and muscle (N: 1), unknown organs (N: 2) obtained from paraffin-embedded blocks of human CE created an acceptable sequence in two directions. All 19 isolates regardless of the organ involved were recognized as E. granulosus sensu stricto (G1).

The sequence alignments of the isolates displayed two profiles. All sequenced samples showed E. granulosus sensu stricto (G1) with no organ-related genotype.

''Lichtenstein'' tension-free mesh repair is the most common surgical techniques used for inguinal hernia repair." Read-Rives" method is tension-free, too, but here prosthesis is placed just over the peritoneum, and there is no weak area. The aim of this study was to compare the results of "Read-Rives" and Lichtenstein method in the hernioplasty. Methods and Materials: In this prospective randomized clinical trial 126 patients who had unilateral inguinal hernia were examined: 64 patients operated with Lichtenstein and 62 patients operated with Rives method. They evaluated for early post-operative complications, duration of surgery and hospital stay, return to normal activity, and then they followed for recurrence of hernia.

Postoperative pain was significantly lower and the return to normal activity was shorter in Rives group. Duration of surgery and hospital stay and recurrence rate was equal, lower postoperative wound infection was found within Rives method.

Although the ''Read-Rives'' method is not technically as simple as ''Lichtenstein'' method, but this procedure is easy to learn, so it is recommended because of its better final outcome in comparison with Lichtenstein repair.
