Pulmonary fissures separate human lungs into five distinct regions called lobes. Detection of fissure is essential for localization of the lobar distribution of lung diseases, surgical planning and follow-up. Treatment planning also requires calculation of the lobe volume. This volume estimation mandates accurate segmentation of the fissures. Presence of other structures (like vessels) near the...

The objective of this paper is to develop a segmentation system in order to assist the surgeons to remove the portion of lung for the treatment of certain illness such as lung cancer, and tumours. The fissures of lung lobes are not seen by naked eyes in low dose CT image, there is a proposal for automatic segmentation system. The lung lobes and nodules in CT image are segmented using two stage ...

INTRODUCTION Health-related quality of life (HRQL) is a significant factor in describing the burden of illness and the impact of treatment in patients with gastrointestinal disease. Type D (distressed) personality is defined as the co-occurrence of negative affect and social inhibition. AIM To assess the prevalence of type D personality in patients with anal fissure and to investigate whether...

This paper proposes an automatic lung lobe segmentation method in a supervised way. The lung image is given as input and the lung image is segmented using iterative threshold method. Then fissure information is enhanced using log supportive filter. Then Fissure locations are extracted using Vector training and matching process. Finally the lung lobes are segmented and marked as individual lobes...

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited rol...

OBJECTIVES To evaluate the effectiveness of Botulinum toxin injection in the treatment of anal fissure. METHODS 38 patients (22 males, 16 females; mean age (SD) of 33.3 (8.3) years) who have presented to Surgical Outpatient Clinic at Al Ain Hospital, United Arab Emirates, with anal fissure in the period between June 2000 and September 2001 and treated with Botulinum toxin injection were retro...

Fistula in ano commonly develops as a chronic sequela to an asymptomatic or symptomatic abscess in an anal canal gland, i.e. cryptoglandular in origin [1]. It occurs in upto one third of patients who undergo drainage of an anorectal abscess [2]. Complex, recurring fistulas could develop secondary to trauma, infection, radiation or chronic granulomatous infections (tuberculosis, actinomycosis) [3].

Abstract Fistulectomy followed by healing by secondary intention, even though, the most commonly used technique for treatment of low fistulain-ano has its associated post-operative long healing time and morbidity. A better alternativ...

OBJECTIVE The aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles. MATERIALS AND METHODS This in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-TCP nanoparti...
