ABSTRACT
OBJECTIVE: To determine the age related prevalence of Varicella Zoster Virus (VZV) antibodies in India. SETTING: This was a cross sectional multicentric study performed in 4 major cities of India: Calcutta (outpatients), Mumbai (outpatients), Lucknow (walk-in patients to a diagnostic laboratory, orphanage and factory workers) and Bangalore (outpatients and walk-in patients to a diagnostic laboratory). METHODS: A total of 1609 volunteers from birth to 40 years of age were included into the study. IgG antibodies against VZV were determined using commercial kits (ELISA-Enzygnost). RESULTS: Overall seroprevalence of anti VZV antibodies was 68. 22percnt. The age related seroprevalence rate of anti VZV antibodies was 29percnt in the age group of 1-5 years, 51.1percnt in 5-10 years, 71.7percnt in 11-15 years, 79.8percnt in 16-20 years, 88.1percnt in 21-30 years and 91.1percnt in 31-40 years. CONCLUSION: A significant proportion of adolescents and adults are susceptible to varicella in India, as in other tropical countries

This paper addresses our experience with primary (15 patients) and secondary (8 patients) tracheo-oesophageal puncture (TEP) in the laryngectomee. Despite a success rate of 93.3 percent in the primary TEP and 62.5 percent in secondary TEP, in a follow-up period of one month to eight years, prosthesis related problems like maintenance and recurring expenses emerged as significant deterrent factors in adopting prosthetic speech rehabilitation. Successful oesophageal speech training, increased practice of Pearson's near total laryngectomy, prior tracheostomy and advanced disease mandating post-operative radiotherapy in majority of patients are some of the factors in addition to prosthesis after-care maintenance that makes TEP a less practiced option at our center.

Re-establishment of effective communication following laryngopharyngo esophagectomy and gastric transposition requires thorough knowledge and flexibility of introducing the entire range of communication options. This study describes our experience with eleven patients of gastric transposition who attended intensive speech therapy and developed gastric speech using different method of speech producing and attaining various levels of proficiency. Application of digital pressure is one of the most effective technique for production of satisfactory and intelligible voice in gastric transposition cases who fail to develop speech by inhalation method.
