Background: Patients with cholestatic liver function tests and histological features of primary sclerosing cholangitis (PSC) but a normal cholangiogram are considered to have small duct PSC. The natural history of this condition is unknown. Methods: Thirty three patients with small duct PSC were identified among patients admitted for diagnostic workup of cholestatic liver function tests in one ...

OBJECTIVES We attempted to clarify the mechanism underlying lower bile duct stricture in autoimmune pancreatitis. METHODS Imaging and histologic finding of the bile duct were assessed for 73 patients with autoimmune pancreatitis to clarify whether IgG4-related biliary inflammation or pancreatic head swelling is associated with lower bile duct stricture. RESULTS Lower bile duct stricture was...

A request on ventilation systems today is the feature of a low noise level. A common method to attenuate ventilation noise is to use passive silencers. However, such silencers are not suitable for the lowest frequencies and one solution is to use active noise control (ANC) to increase the noise attenuation in the low frequency range. Normally when using a feedforward ANC system to attenuate duc...

Thyroglossal duct cyst is a well-known congenital entity, and its embryonic development and clinical presentation are well understood. Very little can be added to the classic material found in the world literature. Rare cases of unusual clinical presentation have also been reported. Our case of endolaryngeal thyroglossal duct cyst is reported because of its unique endolaryngeal presentation...

Incidence of aneurysm of the anterior spinal artery is known to be very low and the standard treatment strategy has not yet been established. The author experienced a case of subarachnoid hemorrhage (SAH) caused by the rupture of an aneurysm in the branch of the cervical anterior spinal artery, which was managed conservatively. The patient had end-stage common bile duct cancer and survived for ...

Ejaculatory duct obstruction (EDO) underlies 1-5% of male infertility, although the diagnosis of EDO can be complex, treatment is well established and can be very effective. Part of reason that this condition probably is underdiagnosed, is because of its rarity, subtle presentation and the concomitantly low index of suspicion held by physicians. The causes of EDO are divided into congenital and...

Abstract Taking the limestone gypsum wet desulfurization oxidation air duct of a 660 MW coal-fired unit in power generation enterprise as research object, new type bubble crushing and retention device with wing span baffle structure was simulated optimized using CFD numerical simulation technology. The results showed that time bubbles slurry final design scheme about 10.4 seconds, significantly...

An experimental investigation was conducted to study the average and the fully-developed heat (mass) transfer coefficients in a rectangular smooth duct and a duct with repeated-baffle blockages. The focus of attention in this work is the conventional correlation Nu / Nufd 1 + C / ( X / D ) for the average heat transfer coefficient. It was shown that for relatively short ducts, the coefficient C...
