UNUSAUAL PRESENTATION OF SUBMANDIBULAR DUCT AND GLAND CALCUI: CASE REPORT

Sialolithiasis is one of the most common pathologies of the submandibular gland; sialoliths account for about 80 percent of all salivary duct calculi.The majority of sialolith occurs in the submandibular gland or its duct and is common cause of acute and chronic infection. Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, and their management has always been a therapeutic challenge. This report presents the two unusual and rare cases of large sialolith of the submandibular duct as well as gland measuring 70x11mm and 54x25mm respectively.

Optical absorption in boron clusters B6_{6} and B6+_{6}^{+} : A first principles configuration interaction approach

The linear optical absorption spectra in neutral boron cluster B$_{6}$ and cationic B$_{6}^{+}$ are calculated using a first principles correlated electron approach. The geometries of several low-lying isomers of these clusters were optimized at the coupled-cluster singles doubles (CCSD) level of theory. With these optimized ground-state geometries, excited states of different isomers were computed using the singles configuration-interaction (SCI) approach. The many body wavefunctions of various excited states have been analysed and the nature of optical excitation involved are found to be of collective, plasmonic type.Comment: 22 pages, 38 figures.

COMPARATIVE STUDY OF MANAGEMENT WITH MYRINGOPLASTY AND CHEMICAL CAUTERISATION IN TUBO-TYMPANIC TYPE OF CHRONIC SUPPURATIVE OTITIS MEDIA

Introduction CSOM is highly prevalent chronic ear disease. In developing countries like India, where tertiary medical facility is not available to all people, treatment should be cost effective and easily feasible at even primary health centre. With this background a study was performed for closure of small to moderate central perforation with chemical cauterisation and to see whether it is equally effective as that of Myringoplasty or not.Study design: prospective clinical study.Methodology: To compare results of chemical cauterisation (TCA) with myringoplasty on non healing small and medium sized central tympanic membrane perforation of pars tensa, 100 patients with dry tympanic membrane perforations. Result:1) Success rate with myringoplasty and chemical cauterisation were 76% and 72% respectively.2) The improvement of hearing at 3rd month of follow-up after successful procedure with myringoplasty and chemical cauterisation in term of air bone gap less than 10 db were 68.4% and 88.88% respectivelyConclusion:1) For closure of small central perforation chemical cauterisation is equally effective as myringoplasty.2) For closure of moderate central perforation, myringoplasty is superior to chemical cauterisation.3) Hearing improvement was observed better for chemical cauterisation as compared to Myringoplasty.
