Objectives: To use an electroglottography (EGG)-based videostroboscopy tool to assess the anatomical and morphologic characteristics of the pharyngoesophageal (PE) segment in tracheoesophageal (TO) speakers. Study design: Cross-sectional cohort study. Subjects: Fifty-two post-laryngectomy patients with no recurrence and using prosthetic (Blom-Singer) speech. Intervention: An electroglottography (EGG)-based videostroboscopy tool EGG-based rigid videostroboscopy as well as perceptual evaluation. outcome Measures: Stroboscopic protocol included nine subjective/visual parameters to evaluate the neoglottis and study correlation of the G (GRBAS scale) and the overall voice quality (OVQ) with the treatment variables. Results: Of the 52 laryngectomees, videostroboscopic recordings were possible in 46 patients (36 males and 10 females) with a mean age of 63.4 ±10.5 (SD) an electroglottography (EGG)-based videostroboscopy tool years. All used the Blom-Singer valve and the median time since Total Laryngectomy was 2 years. The neoglottis was assessable in 26 patients. We were able to strobe only 9 patients. There was excellent correlation between G and OVQ (Spearman rho > 0.9). Statistically significant correlation was found between G1 and saliva (P = 0.03) and between good OVQ and saliva (P = 0.02); similarly, there was significant correlation between G1 and LVV (P = 0.05) and between good OVQ and LVV (P = 0.03). Conclusions: This study is the first to examine the use of an EGG-based stroboscopy instrument to evaluate TO speech. Our observations suggest that from the standpoint of functional voice, saliva and the LVV had statistically significant effect in determining voice quality. [ABSTRACT FROM AUTHOR]

Total laryngectomy or laryngopharyngectomy remains the procedure of choice for advanced-stage (UICC T3 and T4) laryngeal carcinoma around the world despite advances in conservative laryngeal surgery and radiotherapy. However, it has profound effects on respiration and deglutition, in addition to the most disabling effect--the loss of verbal communication. Successful voice restoration can be attained with any of three speech options, namely esophageal speech, electrolarynx, and tracheoesophageal (TO) speech using an artificial valve. Although, no single method is considered the best for every patient, the tracheoesophageal puncture has become the preferred method in the past decade. Several types of voice prostheses have been produced since the first prosthesis was introduced in 1980 by Blom and Singer. However, eventually all prostheses are confronted by the same problem, i.e., the development of a biofilm, leading to deterioration and ultimately to dysfunction of the prostheses, necessitating replacement. This article attempts to sum up the historical background as well as the current state of surgical voice rehabilitation following laryngectomy; we review the recent major advances as well as the future prospects. Data was collected by conducting a computer-aided search of the MEDLINE and PubMed databases, supplemented by hand searches of key journals. Over 50 articles published in the last three decades on the topic have been reviewed, out of which about 20 were found to be of relevance for this article. [ABSTRACT FROM AUTHOR]

The author reflects on a accumulated evidence revealing that tumor growth and propagation are dependent on a subset of cells called cancer stem cells (CSCs). He believes that the identification and characterization of the CSCs through molecular markers can contribute in formulating effective targeted therapies as well as prevent tumor recurrences. He also stresses that CSCs are obtained from the normal stem cells of the body which played a crucial role in an organogenesis of an individual.

Quality of life (QOL) is a multidimensional construct that minimally includes broadly defined assessments of the physical, psychological, and social domains of functioning. However, measuring this QOL is complicated by the fact that there are many different validated questionnaires available. In India, with people now wanting self-directed care and greater autonomy, we must direct increased efforts towards QOL and its assessment. We propose the Assessment, Translation & Validation, Application and Audit method to increase the use of QOL scales in our country. [ABSTRACT FROM AUTHOR]
