Introduction: Evaluation of upper airway space is a routine procedure in orthodontic diagnosis and treatment planning. Although limited insofar as they provide two dimensional images of three-dimensional structures, lateral cephalometric radiographs have been used routinely to assess airway space permeability. Cone-Beam Computed Tomography (CBCT) has contributed to orthodontics with information...
BACKGROUND Recurrence is common after total laryngectomy for advanced laryngeal carcinoma. The aim of the present study was to review the prognosis of recurrent laryngeal carcinoma after total laryngectomy. METHODS The records of 165 patients who developed recurrences after total laryngectomy for laryngeal squamous cell carcinoma between January 1971 and December 1990 were reviewed. RESULTS...
Can Multi-Detector Computed Tomography (MDCT) Help in Differentiation of Neoplastic Parotid Lesions?
Background: Parotid lesions are uncommon issue in clinical practice with wide differential diagnosis based upon multiple pathological varieties and limited clinical values. Computed tomography (CT) try to solve this issue as possible. Objectives: To evaluate the diagnostic reliability of multi-detector computed tomography (MDCT) in characterization of benign and malignant parotid lesions using ...
Purpose. The upper airway space is significant in orthodontic diagnosis and treatment planning. The objectives of this study are to assess the dimensions of soft tissue elements of the upper pharyngeal space and evaluate potential correlations with modifying variables such as gender, skeletal class, and anthropometric parameters. Materials and Methods. Lateral cephalograms were obtained from 11...
Objective/Hypothesis Comparing detection and extension of malignant tumors by flexible laryngoscopy in the outpatient setting with under general anesthesia using both White Light Imaging (WLI) Narrow Band (NBI). Study Design Prospective study. Methods Two hundred thirty-three patients laryngeal pharyngeal lesions underwent rigid laryngoscopy, WLI NBI. Extension (n = 132) was compared between te...
Once the regional lymph nodes become involved in prostate carcinoma, 85% of patients develop distant metastases within 5 years, and metastatic disease is difficult to treat. We have investigated the effect of systemic interleukin 2 (IL-2) treatment on metastatic prostate carcinoma using a xenograft tumor model. Cells from a PC-3/IF cell line, produced by intrafemoral injection of human PC-3 pro...
OBJECTIVE In this study we utilized the Surveillance, Epidemiology and End-Results (SEER) registry to identify risk factors for lymphatic spread and determine the incidence of pelvic and para-aortic lymph node metastases in patients with uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) who underwent complete surgical staging and lymph node dissection. METHODS ...
In this paper we introduce the concept of (ε)-almost paracontact manifolds, and in particular, of (ε)-para Sasakian manifolds. Several examples are presented. Some typical identities for curvature tensor and Ricci tensor of (ε)-para Sasakian manifolds are obtained. We prove that if a semi-Riemannian manifold is one of flat, proper recurrent or proper Ricci-recurrent, then it can not admit an (ε...
BACKGROUND Human papillomavirus type 16 (HPV16) seropositivity and alcohol and tobacco use have been associated with risk of head and neck squamous cell carcinoma (HNSCC). However, it is less clear whether HPV16 influences HNSCC risk associated with alcohol and tobacco use. METHODS Incident cases of HNSCC diagnosed between December 1999 and December 2003 were identified from nine medical faci...
