Comparative studies of the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of ^{25}Mg^{+}

We have employed the relativistic coupled cluster theory to calculate the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of singly ionized magnesium. Comparison with experimental and the other theoretical results are done and predictions are also made for a few low lying excited states which could be of interest. We have made comparative studies of the important many body effects contributing to the hyperfine constants for the different states of the ion.Comment: 3 figures, Late

Sure Shot Technique for Management of Ranula

Introduction Ranula is a pseudocyst in the floor of the mouth originating from the sublingual salivary gland.A variety of surgical procedures have been quoted in the literature. But the main concern is high rate of recurrence. Aim of the present study is to describe a definitive technique for managing ranula and compare the result with review of literature. Materials and Methods A prospective study was done in the department of ENT in a tertiary care hospital of West Bengal from 1st April, 2014 to 31st March, 2019. Patients presenting with ranula irrespective of age and sex; size of the mass; whether primary or recurrent case were included in the study. Patients presenting with congenital and plunging ranula were excluded. Patients were treated with total excision of ranula along with sublingual salivary gland. Patients were followed up regularly for at least one year post-operatively. Results We treated thirteen primary and four recurrent cases of ranula. Among them eight were male and nine were female. Patients were from seven to thirty three years of age with most being in the second decade of life. There was no injury to lingual nerve or submandibular duct in any patient. We did not observe any recurrence till date. Conclusion Successful management of a ranula includes identification of the extent of the cyst and removal of the cyst along with the sublingual salivary gland.  When done meticulously, this technique gives 100% success without any complication
