In patients with severe emphysema, bronchoscopic lung volume reduction using one-way valves is a promising therapeutic option to improve lung function and quality of life. The goal of this treatment is to achieve a complete lobar atelectasis. In a significant proportion of patients, this atelectasis cannot be achieved due to interlobar collateral ventilation. This collateral ventilation is gene...

Background: Sealant therapy is the safe and effective way to prevent dental caries in newly erupted teeth. Success of sealant therapy depends on the good isolation, patient corporation and the decrease step for the application of sealant. Aim: Comparative evaluation of marginal microleakage of conventional fissure sealants and self-adhering flowable composites as fissure sealant in permanent te...

PURPOSE The purpose of this in vitro study was to determine the effect of different cleaning methods and the use of post-etching drying agents, as well as the influence of fissure types on the microleakage and penetration ability of fissure sealants. METHODS Ninety extracted human molar teeth were randomly divided into 9 groups of 10 each. The treatment groups were defined by the combination ...

Epidermoid cysts are common benign tumors comprising around 1% and 2% of all intracranial tumors. Their usual locations include the parasellar region cerebellopontine angle, less commonly, Sylvian fissure, suprasellar region, cerebral, cerebellar hemispheres. located in brain stem rare. These epidermoid similar to epidermoids arising skin which contain cheesy flaky-white soft pultaceous materia...

Background and objectives: Anal fissure is a painful wound in the anoderm and distal to dentate line, the chronic fissure leads to hypertrophy and fibrosis. In this study, we compared partial and total sphincterotomy in patients with chronic anal fissure. Methods: In this comparative cohort, 100 patients (52 female and 48 male )mean age 43.34 ± 15.28 year...

OBJECTIVE Surgical approaches to ambient cistern lesions are complex. We investigated the microanatomy of the transtemporal-transchoroidal fissure approach to the ambient cistern with emphasis on exposure of the posterior cerebral artery. METHODS Dissections were performed bilaterally in five silicone-injected cadaveric heads. Critical anatomic distances, specifically with reference to the P2...

Background: Fissure-in-ano is one of the most common benign anorectal disorders often encountered in surgical outpatient department. Various pharmacological agents and interventions have been tried management fissure ano. In this study we compared medical by topical diltiazem gel with established procedure lateral internal sphincterotomy (LIS) chronic anal fissure. Methods: A total 50 patients ...

PURPOSE to assess the distance of the fetal cerebral fissures from the inner edge of the skull by three-dimensional ultrasonography (3DUS). METHODS this cross-sectional study included 80 women with normal pregnancies between 21st and 34th weeks. The distances between the Sylvian, parieto-occiptal, hippocampus and calcarine fissures and the internal surface of the fetal skull were measured. Fo...

This study consisted of a single centre randomised controlled trial with two parallel arms: an acupuncture group (n = 20) with 27 affected eyes and a sham group (n = 20) with 23 affected eyes. Participants in the acupuncture group received acupuncture treatment once daily, three times weekly for four weeks. Participants assigned to the control group received sham acupuncture, the same protocol ...
