Pattern of Syringomyelia in Presumed Idiopathic and Congenital Scoliosis
Mohanty Simanchal Prosad,Kanhangad Madhava Pai,Saifuddin Sibin,Narayana Kurup Jayakrishnan K. 대한척추외과학회 2021 Asian Spine Journal Vol.15 No.6
Study Design: Retrospective study. Purpose: This study was undertaken to compare the patterns of syringomyelia in patients with presumed idiopathic and congenital scoliosis. Overview of Literature: The incidence of neuraxial anomalies presenting as idiopathic scoliosis ranges from 2% to 14%; the common ones are idiopathic syringomyelia (IS) and Chiari malformation type 1 (CM1) with syringomyelia. Some authors have speculated that scoliosis is caused by the asymmetrical compression of anterior horn cells by a syrinx, which causes an imbalance of the trunk musculature. In congenital scoliosis, syringomyelia is the second commonest cord anomaly, and the deformity progression depends upon the underlying vertebral abnormality, the location of the abnormality, and the age of patient, and is independent of the intraspinal anomaly. Methods: We analyzed the radiological records of 44 consecutive patients with scoliosis and syringomyelia. Of these 44 patients, 13 had IS, 12 had CM1, and 19 had congenital scoliosis. The radiographs were evaluated to determine the curve magnitude, sagittal alignment, side of convexity, and type of vertebral anomaly, if any. T1- and T2-weighted magnetic resonance imaging of the whole spine was analyzed to determine the presence of craniovertebral anomalies, syrinx length, syrinx diameter, and syrinx-cord ratio (SCR). Results: The frequency of left convex curves was 26.1%, with no significant differences across the three groups. The mean length of the syrinx was 7.2±4.9 vertebral levels, and the mean SCR was 0.39±0.2. The mean syrinx length was significantly higher in patients with CM1 and IS, compared to patients with congenital scoliosis. The mean SCR was highest in patients with CM1. In congenital scoliosis, syringomyelia was seen most frequently in patients with a failure of formation, and 63.2% had concomitant cord anomalies. Conclusions: Syrinxes were smaller in size and length in patients with congenital scoliosis, and are distinct from those seen in IS and CM1.

<P>Single crystalline tellurium nanowires were successfully synthesized in large scale by a facile approach of vaporizing tellurium metal and condensing the vapor in an inert atmosphere onto a Si substrate. Tellurium was evaporated by heating at 300° C at 1 torr and condensed on the Si substrate at 100-150° C, in the downstream of argon (Ar) gas at a flow rate of 25 sccm for 30 min. The as-synthesized nanowires have diameters between 100-300 nm and lengths up to several micrometers. The single crystalline nanowires grew in a preferred [0001] direction. The obtained nanowires were highly pure as only tellurium metal was used in the vaporization process, and no other reagent, surfactant, or template were used for the growth. This low temperature and high-yield approach to the tellurium nanowires synthesis may facilitate its industrial production for various applications.</P>
Stabilization of expansive soil using industrial wastes
Mohanty, Soumendra K.,Pradhan, Pradip K.,Mohanty, Chitta R. Techno-Press 2017 Geomechanics & engineering Vol.12 No.1
Swelling and shrinkage characteristics of expansive fine grained soil cause volumetric changes followed by distress and damage to the structures. Soil stabilization can be explained as the alteration of the soil properties by chemical, mechanical or any other means in order to enhance the engineering properties of the soil. Utilization of industrial wastes in soil stabilization is cost effective and environment friendly. This paper presents an experimental study on stabilization of expansive soil using industrial wastes, viz. fly ash and dolochar. The paper includes the evaluation of engineering properties like unconfined compressive strength and California bearing ratio (CBR) of expansive soil collected from Balasore district of Odisha stabilized with fly ash and dolochar in different proportions and to predict the influence of these additives on engineering properties and strength characteristics of expansive soil. Both fly ash and dolochar were found to increase the CBR and decrease many index properties such as liquid limit, plastic limit, plasticity index, swelling index and UCS, thus enhancing the strength parameters of expansive soil.
Fluctuations in global surface scaling behavior in sputter-deposited ZnO thin films
Mohanty, B. C.,Choi, H. R.,Cho, Y. S. Editions de Physique 2011 Europhysics letters Vol.93 No.2
<P>Quantitative analysis of the roughness scaling behavior, which is critical in understanding the evolution of surface microstructure, is reported for ZnO thin films grown by RF magnetron sputtering. The strong dependence of global and local growth parameters on the applied RF powers can be highlighted as a unique observation, which has not been available from the typical super-rough scaling studies. For example, the global growth exponent increased from 0.53± 0.02 at 75 W to 1.03± 0.01 at 200 W. The observed dominant anisotropic growth of crystallites at high powers is believed to be the main reason for the power-dependent roughening behavior.</P>
Assessment of seasonal variations in water quality of Brahmani river using PCA
Mohanty, Chitta R.,Nayak, Saroj K. Techno-Press 2017 Advances in environmental research Vol.6 No.1
Assessment of seasonal changes in surface water quality is an important aspect for evaluating temporal variations of river pollution due to natural or anthropogenic inputs of point and non-point sources. In this study, surface water quality data for 15 physico-chemical parameters collected from 7 monitoring stations in a river during the years from 2014 to 2016 were analyzed. The principal component analysis technique was employed to evaluate the seasonal correlations of water quality parameters, while the principal factor analysis technique was used to extract the parameters that are most important in assessing seasonal variations of river water quality. Analysis shows that a parameter that is most important in contributing to water quality variation for one season may not be important for another season except alkalinity, which is always the most important parameters in contributing to water quality variations for all three seasons.
Role of Dental Institutions in Tobacco Cessation in India: Current Status and Future Prospects
Mohanty, Vikrant Ranjan,Rajesh, Guru Raghavendran,Aruna, D.S. Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4
Tobacco abuse is a major preventable cause of premature death and disease, including various cancers. The Global Adult Tobacco Survey India (GATS) 2009-10 revealed that more than one-third of adults use tobacco in one form or the other. Nearly two in five smokers and smokeless tobacco users made attempts to quit the habit in the past 12 months. Tobacco dependence is a chronic condition characterized by susceptibility of relapse over years. It can be well handled by sustained professional support from health care providers mainly through behavioral counseling and pharmacotherapy. Dental professionals can play a pivotal role in diagnosing and effectively managing tobacco dependence. Dental Institutions have rapidly grown in last two decades across the country and so has the curriculum been adapted to improve student competencies to accommodate changing disease patterns and technological advances, but not in regard to tobacco cessation. Untapped dental manpower like undergraduates, dental hygienists and other paramedical staff need effective training to be more penetrative. The present review paper explores the potential role of dental training institutions and recommends various approaches to counter public health jeopardy of tobacco related diseases.
