Cervical Laminoplasty for Multilevel Cervical Myelopathy
Murali Krishna Sayana,Hassan Jamil,Ashley Poynton
Advances in Orthopedics , 2011, DOI: 10.4061/2011/241729
Abstract: Cervical spondylotic myelopathy can result from degenerative cervical spondylosis, herniated disk material, osteophytes, redundant ligamentum flavum, or ossification of the posterior longitudinal ligament. Surgical intervention for multi-level myelopathy aims to decompress the spinal cord and maintain stability of the cervical spine. Laminoplasty was major surgical advancement as laminectomy resulted in kyphosis and unsatisfactory outcomes. Hirabayashi popularised the expansive open door laminoplasty which was later modified several surgeons. Laminoplasty has changed the way surgeons approach multilevel cervical spondylotic myelopathy.
Cervical Laminoplasty for Multilevel Cervical Myelopathy

Abstract: Cervical spondylotic myelopathy can result from degenerative cervical spondylosis, herniated disk material, osteophytes, redundant ligamentum flavum, or ossification of the posterior longitudinal ligament. Surgical intervention for multi-level myelopathy aims to decompress the spinal cord and maintain stability of the cervical spine. Laminoplasty was major surgical advancement as laminectomy resulted in kyphosis and unsatisfactory outcomes. Hirabayashi popularised the expansive open door laminoplasty which was later modified several surgeons. Laminoplasty has changed the way surgeons approach multilevel cervical spondylotic myelopathy. 1. Introduction Chronic compression of the cervical spinal cord leads to a clinical syndrome of cervical spondylotic myelopathy (CSM). In degenerative cervical spondylosis, herniated disk material, osteophytes, redundant ligamentum flavum, or ossification of the PLL (OPLL) can all cause spinal cord compression. The effect on spinal cord compression is much more pronounced if a patient has a congentially small spinal canal. The aetiopathogenesis, clinical manifestations, investigations, and nonoperative management are discussed in other articles of this special edition. The primary aims of surgical intervention for multilevel myelopathy are to decompress the spinal cord and maintain stability of the cervical spine. Secondary aims are to minimize complications which include long-term pain and motion loss. This can be achieved by anterior approach and/or posterior approach to cervical spine. Anterior approach would involve multilevel discectomy at times with corpectomy and fusion. Posterior approach would involve laminectomy with or without fusion or laminoplasty. This article will focus on cervical laminoplasty for multilevel myelopathy. 2. Evolution of Laminoplasty Kirita, in 1968, devised a sophisticated operative technique, in which the laminae were thinned and divided at the midline using a high-speed drill followed by their en bloc resection to achieve total decompression of the compressed spinal cord [1]. Although this technique improved the results and bettered the technique of conventional laminectomy, complications like postoperative kyphosis and membrane formation resulted. Oyama et al. reported a Z-plasty (Hattori technique) of the cervical spine laminae in 1973 [2]. This procedure was technically demanding and had not been adopted widely other surgeons. In the year 1977, Hirabayashi et al. described an expansive open door laminoplasty (ELAP), which is a relatively easier and safer procedure than laminectomy [3].

Abstract: lncRNAs forms a part of the non coding part of human genome. This term denotes specific non coding RNAs with nucleotide length more than 200. They have been shown to affect various physiological and pathological processes within the human body. Of interest is their role in malignant transformation in several cancers. In this review, the role of lncRNAs in GI cancers namely pancreatic cancer, gastric cancer, hepatocellular cancer and colorectal cancer have been explained in brief. These lncRNAs have shown to be useful as a marker for detection and prognosis of various malignancies. They also have shown to have therapeutic potential. Various relevant lncRNAs in each section has also been mentioned.
Worm under the Skin—An Unusal Case of Filariasis  [PDF]
Murali Krishna, Jaya Manchanda
Surgical Science (SS) , 2018, DOI: 10.4236/ss.2018.94017
Abstract: Background: Filarial disease has a very high prevalence in South East Asian region especially India. It commonly presents as an affliction of the lymphatic system like acute lymphangitis and chronic lymphedema. Presentation of lymphatic filariasis as a subcutaneous nodule is a rare but previously reported scenario. Aim: We discuss a case with incidental detection of filaria in a subcutaneous nodule following excision biopsy. Case Presentation: 20-year-old male patient presented with subcutaneous swelling in left lower chest. Undergoing excision biopsy for same and on histopathological examination was found to be an encysted filarial worm. Conclusion: Such rare presentation of filariasis has been reported earlier also and should be kept in mind.
An Appraisal of Land Use/Land Cover Change Scenario of Tummalapalle, Cuddapah Region, India—A Remote Sensing and GIS Perspective  [PDF]
Yenamala Sreedhar, Arveti Nagaraju, Gurram Murali Krishna
Advances in Remote Sensing (ARS) , 2016, DOI: 10.4236/ars.2016.54019
Abstract: The study was aimed at appraising the changing land use/land cover scenario of Tummalapalle region in Cuddapah district of Andhra Pradesh using Remote sensing data and GIS technology. The region is considered as it has rich uranium reserves and is experiencing a remarkable expansion in recent times. The land use/land cover change analysis was carried out using IRS P6 LISS-III and LANDSAT-8 OLI multitemporal data pertaining to the years 2006 and 2016. The image classification resulted in five major land use/land cover classes namely built-up, agricultural, forest, wasteland and water bodies. The study noticed that the areas under built-up and agricultural classes are found increased from 0.94 km2 (0.84%) to 2.75 km2 (2.44%) and 61.68 km2 (54.84%) to 63.91 km2 (56.82%), respectively during 2006-2016. Area under forest, wasteland and water bodies are found decreased considerably from 3.09 km2 (2.75%) to 0.86 km2 (0.76%), 43.71 km2 (38.56%) to 42.60 km2 (37.88%) and 3.05 km2 (2.71%) to 2.35 km2 (2.09%), respectively. The study recommends development of industrial based economy by optimally utilizing the existing land resource (scrub and wasteland classes) and simultaneously extending the agricultural practices to other possible areas to make them more productive.

Mapping of Soil Erosion Zones of Meghadrigedda Catchment, Visakhapatnam, India for Conservation
—A Geospatial Approach
 [PDF]

Usha Chirala, Murali Krishna Gurram, Nooka Ratnam Kinthada
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.64026
Abstract: Meghadrigedda, a non-perennial drainage system is one of the major water resources of Vishakhapatnam city located in the northern coastal region of Andhra Pradesh, India. It traverses through the hilly terrain of Eastern GhatMobile Belt (EGMB) characterized by khondalitic rock formations. Excessive siltation scenario aggravated due to soil erosion in its catchment is threatening the very existence of Meghadrigedda reservoir. In order to assess the intensity of soil erosion as well as silt deposition in the reservoir, an integrated study has been undertaken which takes into consideration various topographic, morphological, soil, and land use/land cover characteristics of the basin. The study aims at identification and mapping of erosion prone zones with respect to silt deposition using remote sensing and GIS techniques.Alteration in human induced land use practices in its catchment due to rapid growth in population, urbanization and industrialization are found to be of prime reasons for various forms of erosion. The study has noticed that various forms of erosion like sheet, gully and stream erosion are responsible for the siltation at large scale which is causing reduction of its designed storage capacity by 40%. Various sub-watersheds of the basin have been prioritized on the basis of erosion intensity for suggesting various mitigation measures like check-dam construction, afforestation etc. to protect the reservoir from the silting problem.

Gurram Murali Krishna, Kinthada Nooka Ratnam, Pekala Ravi, Panuganti Sridhar
Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.75038
Abstract: Recent advancements in internet mapping technology, efficient geospatial data management systems, and availability of different GIS API’s have revolutionized the way in which the geospatial data is being used, shared and represented through distributed systems for business applications. However, development of powerful, highly functional, yet cost- and time-effective enterprise WebGIS business systems requires a very robust and highly scalable architecture. The architecture should have the inherent characteristics of rapid development, a well-defined object library and at the same time it should comply with the existing geospatial interoperability standards defined by Open Geospatial Consortium (OGC). On the other hand, development of extendible distributed business GIS systems requires the presence of tailor-made inbuilt models available as modules which can be extended further by readily implementable user-interface templates supported by object modeling environment which allows for custom design and delivery of the processes and map output. There are various commercial and open source web mapping solutions which offer a great deal of flexibility and functionality. Nevertheless, they restrict the user community with certain limitations, in terms of functionality, cost or complexity. This necessitates, defining a new approach which efficiently caters the user requirements and not limiting them with aforementioned shortcomings. This paper aims to evaluate various architectural alternatives for delivering robustdistributed GIS business solutions and also attempts to give an account of an implementable instance of a WebGIS architecture which can cater the multi-user and multi-industry requirements.
