    Abstract The two shunts that are performed much less and are included here for completeness are the ventriculosubgaleal shunt and the ventriculocholecystal shunt. The ventriculosubgaleal shunt is an established treatment of hydrocephalus following germinal matrix hemorrhage in low-birth-weight neonates. It is also used in the treatment of post-infective hydrocephalus in children. In our institution protocol, we have used this shunt in a wide variety of indications, especially in children below six months of age. Ventriculocholecystal shunts are very much a salvage shunts when all else fails.

    Abstract The study has pivoted on finding a methodology to forecast the end day of the menace of Coronavirus Disease of 2019 (COVID-19) or such pandemic that the planet faces on and often, challenging the core of the civilization. This model has resort to an indirect method to find the end day. As the pandemic grows exponentially, the rate of growth of total cases over previous day reduces asymptotically with herd immunity gaining strength to strength. Instead of finding flat head of the exponential expansion path, the model has looked into close to zero value of daily growth rate to find the end day. ARIMA (p,q,r) model for data smoothing and exponential trend line methodology adopted to find the end day. COVID-19 data for 63 days from March 20, 2020 to May 21, 2020 for seven countries and the globe explored with the proposed methodology. The study has projected toll of COVID-19 using a continuous constant exponential growth/decay model. The end day of the pandemic is projected for the globe when the expansion of the disease would be 0.01% per day. The methodology can be improved further by inclusion of other parameters of social and virology implications.

    Abstract The ravage of COVID-19 has remained unprecedented in the history of human civilization. The pandemic has bewildered the governments across the nations amidst the twin edge blade of economic stringency or unabated growth of the disease. The study has attempted to find the efficacy of GovernmentIntervention (GI) incombating the forces of the pandemic. Ithas pooled historical data of victims of 13 most affected countries after smoothening the data with ARIMA(p,q,r) technique to formulate an exponential model for its spread. The model considers six explanatory variables including GI to understand the dynamics of the disease. The historical data of the countries pooled across continents to have six groups. While variance inflation factorused for detecting multicollinearity, multivariate regression model adopted to determine the association between the explanatory variables and COVID-19 growth. The study pivoted on finding the role of GI, looking at its association with COVID-19 spread. Comparability analysis of the coefficient of GI conducted across the models to find the intensity across the continents. The study finds GI an effective instrument in the continents of America (North), America (South) and Asia, conducive for buying time for herd immunity and invention of vaccine and/or medicine.

    Abstract Background: Primary hypophysitis is a rare condition, usually diagnosed retrospectively after surgery for a suspected pituitary adenoma. Improved awareness of the condition and better imaging have resulted in more patients being diagnosed without surgery.
    Objective: A retrospective chart analysis study of hypophysitis from a single secondary endocrine and neurosurgical referral center in eastern India was conducted between 1999 and 2021 to assess the diagnostic and therapeutic challenges posed by these patients.
    Methods and material: Fourteen patients presented to the center between 1999 and 2021. All patients had an MRI of the head with contrast and a full clinical workup. Twelve patients had headache, of whom one had progressive visual impairment. One patient had severe weakness, attributed later to hypoadrenalism and one had sixth nerve palsy.
    Results: Six patients had glucocorticoids as their primary treatment, four refused treatment, and one was on glucocorticoid replacement. One patient had decompressive surgery because of progressive visual loss, and two had surgery because of a presumptive diagnosis of pituitary adenoma. There was no difference between the patients who had glucocorticoids and those who did not.
    Conclusions: Our data suggest that it is possible to identify most patients with hypophysitis on clinical and radiological grounds. In the largest published series on this subject and in ours, glucocorticoid treatment did not alter the outcome.
