Recently, balloon enteroscopy has made possible the use of endoscopic approaches to the surgically reconstructed intestine [1–4], so that hepaticojejunostomy strictures can be treated endoscopically. We describe the successful endoscopic dilation of a severe hepaticojejunostomy stricture with a wire-guided diathermic dilator (6-Fr, 180-cm Cysto-Gastro-Set; Endo-flex, Voerde, Germany) (●" Fig.1)...

Seven pure-culture strains of fungi cultivated by attine ants (ant-garden fungi) were isolated from locally maintained leaf-cutting ant colonies. An ant-garden fungus strain obtained from an Atta cephalotes colony, when offered to ants of the colony from which the fungus was isolated, was accepted as their own. Young fungus cultures were harvested and incorporated into the fungus garden, and cu...

OBJECTIVE The aim of this study was to identify human papillomavirus (HPV) in cervical intraepithelial neoplasia (CIN) lesions and to evaluate the persistence of viral DNA after diathermic large loop excision (DLLE) treatment. STUDY DESIGN Biopsies from 36 patients with low- and high-grade CIN lesions were studied before and after DLLE treatment looking for HPV sequences. DNA was extracted to...
