Sixteen lymph nodes from 14 patients with rheumatoid arthritis were examined immunohistochemically and morphometrically and compared with 10 control nodes showing follicular hyperplasia from patients without rheumatoid disease. Frozen material was available from nine patients and all controls. The nodes from patients with rheumatoid arthritis seemed to share characteristic features. The most st...

Background: The ovarian neoplasms are the cause of highest mortality in female genital tract. Histomorphological study is the gold standard to assess the treatment modalities and prognosis of various tumors. Aim: This study is done to determine the age incidence, prevalence and morphological variants of ovarian neoplasms Materials and methods: This is retrospective and prospective study done fr...

Introduction: Studying the position of mental foramen and its morphological variations help to localize the mental nerve and thus prevent complications during surgical procedures. Materials and Methods: This study was conducted in 40 dry adult human mandibles in the department of anatomy, Teerthanker Mahaveer Medical College and Research Center. Parameters like incidence, position, direction, s...

DESIGN Multicenter retrospective study. SETTING University hospitals in Spain, Italy, Argentina, New York City, and Austria. PATIENTS Th...

The cystic artery is the key structure sought to be clipped or ligated during laparoscopic or conventional cholecystectomy. The possible complications like hemorrhage or hepatobiliary injury are always centered on the search, dissection, and clipping or ligation of the cystic artery, many a time because of possibility of variations in its course and relations to the biliary ducts. This descript...
