Here, we report an extremely rare case of acquired nasolacrimal duct obstruction caused by oncocytic carcinoma. A 64-year-old man presented to the hospital complaining of epiphora and left-side nasal obstruction. Ophthalmic and otolaryngology examination revealed a left lacrimal duct obstruction caused by a mass in the left nasal cavity and lacrimal drainage system. The mass was removed and con...

ABSTRACT Members of the Hydrophilidae, one largest families aquatic insects, are potential models for biomonitoring freshwater habitats and global climate change. In this study, we describe morphology male reproductive tract in water scavenger beetle Tropisternus collaris. The sexually mature males comprised a pair testes, each with at least 30 follicles, vasa efferentia, deferentia, seminal ve...

Pancreatic duct obstruction, even in the absence of biliary obstruction and/or bile reflux into the pancreatic duct, can trigger acute hemorrhagic necrotizing pancreatitis. The earliest changes are seen within acinar cells. Early derangements in acinar cell biology include inhibition of digestive enzyme secretion and the co-localization of lysosomal hydrolases with digestive enzyme zymogens. Un...

OBJECTIVE To determine the etiology of Hilar malignant biliary strictures and the efficacy of hepaticojejunostomy in it's management with or without segmental liver resection. PATIENTS AND METHODS A retrospective study of 33 patients was carried out at Civil Hospital & Lyari General Hospital Karachi. They presented with signs and symptoms of mechanical cholestasis. Study was conducted to find...

BACKGROUND The most common cause of perihilar obstruction is cholangiocarcinoma, especially in Thailand. Benign perihilar stricture represents less than 20% of cases. IgG4-related disease and IgG4-related sclerosing cholangitis, however, have been receiving increased recognition. Isolated IgG4-related sclerosing cholangitis is less common. The preoperative diagnosis of IgG4-related sclerosing c...

Many different benign and malignant diseases can cause extrahepatic biliary duct obstruction. Common causes include calculus of the bile duct, stenosis, and tumors. Bile duct obstruction is often complicated bybacterial infection due to acute cholangitis, leading toan increase in the bile duct pressure and entry ofa large number of bacteria and toxins into the blood circulation. Consequently, a...

Background: Obstruction of the nasolacrimal duct is the most common abnormality of the lacrimal system in childhood leading to epiphora. It is found in about 20% of newborns. If not treated in time, it may be complicated by recurrent conjunctivitis, chronic dacryocystitis, and lacrimal abscess formation. Objectives: To study the outcome and complications of probing for congenital nasolacrimal d...

A case of cystic fibrosis complicated by common bile duct stenosis is described. Surgery successfully relieved the obstruction, but was complicated by Candida septicaemia. The previously unreported histological abnormalities of the common bile duct are discussed.

PURPOSE To verify the results of balloon-catheter dilatation for the treatment of congenital lacrimal duct obstruction. To the best of author's knowledge this procedure has not been previously used in Brazil and deserves scientific studies. METHODS Children between 2 and 5 years old, with congenital lacrimal duct obstruction, were treated with balloon-catheter dilatation (Lacricath). Catheter...
