purpose: to determine long-term outcomes of probing in adult patients with nasolacrimal duct (nld) obstruction. methods: patients older than 20 years admitted in labaffinejad hospital with complete nasolacrimal duct obstruction were studied. the selected patients underwent probing under local anesthesia and cases with successful nld probing enrolled the study. patients were examined during the ...

background: transcatheter occlusion of the patent ductus arteriosus (pda) is a minimally invasive treatment. the appropriate device size is chosen based on the angiographic measurement of the pda . the current study aimed to assess the relationship between the transthoracic echocardiographic (tte) measurements of the pda prior to the occlusion procedure and the actual size of the deployed devic...

the star-mesh transformation allows the reduction of nodes in an electrical circuit. the gauss elimination method allows the reduction of unknowns in a system of linear equations . triangular decomposition can be used to find the inverse of a matrix. in this paper the coherence between these methods are discussed. it is shown that the gauss elimination method gives the same formula for star-mes...

carcinoid tumors of the bile duct are rare. despite cholangiocarcinoma, they grow more slowly and generally occur in younger patients and females. these tumors have a better prognosis and more disease-free survival. we present the case of a 25-year- old male with common bile duct (cbd) carcinoid tumor misdiagnosed as cholangiocarcinoma.
