Comparative study of lichtenstein’s hernia repair under local anaesthesia and spinal anaesthesia

Inguinal hernia is one of the most common disease in male population. Treatment is surgical. While in the past, hernia surgery was done under general and spinal anaesthesia, in recent years the role of local anaesthesia plays a major role in terms of cost effectiveness, patients cooperation on table and time saved during surgery. AIM OF THE STUDY: To compare safety and effectiveness of lichtenstein repair under local anaesthesia versus spinal anaesthesia in relation with post operative pain, complications and hospital stay. MATERIALS AND METHODS: This prospective study of 50 cases of unilateral inguinal hernia admitted in Government Mohan Kumaramangalam Medical College Hospital, Salem was done in the period from DECEMBER 2015 to SEPTEMBER 2017. The cases were evaluated through proper history taking, clinical examination, operative procedure and post operative follow ups. OBSERVATION: In our study the mean age in Group A was 44.36+/-11.69 and in group B was 40.44+/-10.18. Incidence of indirect inguinal hernia was common in age group of 21 to 45 years in group A and 22 to 47 years in Group B. Direct hernia incidence was common in age group 47 to 71 years. The time taken for hernioplasty under local anaesthesia was from 40 mins to 70 mins but to finish under spinal anaesthesia was prolonged from 40 mins to 100 mins. Hence local anaesthesia was a better choice. The pain felt during surgery was significantly less in group A when compared to group B.Postop pain was measured using the visual analogue scale at 12 hrs , 24 hrs and 48 hrs.Mean pain was significantly less in group A as compared to Group B. Post operative complication were high in Group B when compared to Group A. Patients had complications like urinary retention, headache. Spinal anesthesia related complications were high. The number of analgesic doses received postoperatively was more in group A was very less compared to Group B. around 8 patients in group B received 5 to 6 analgesic doses postoperatively. Mean analgesic dose received in Group A patients (2.12+/-1.23) as compared to Group B patients ((3.44+/-1.58) Number of days of hospital stay was significantly less in Group A when compared to Group B. 19 patients in group B had to stay 3 to 5 days in the hospital whereas in group A most of the patients were discharged on day 1 or 2. Group A patients were cost effective than Group B when the drugs used, number of analgesic doses used and number of days of hospital stay are considered. CONCLUSION: Lichtenstein tension free hernioplasty under local anaesthesia is an extremely safe day care operation. It is inexpensive and effective procedure and the benefits are low morbidity and early return to normal activities.It results in faster recovery speedy discharge and less anaesthesia related complications

Business Analytics in (a) Blink

The Blink project’s ambitious goal is to answer all Business Intelligence (BI) queries in mere seconds, regardless of the database size, with an extremely low total cost of ownership. Blink is a new DBMS aimed primarily at read-mostly BI query processing that exploits scale-out of commodity multi-core processors and cheap DRAM to retain a (copy of a) data mart completely in main memory. Additionally, it exploits proprietary compression technology and cache-conscious algorithms that reduce memory bandwidth consumption and allow most SQL query processing to be performed on the compressed data. Blink always scans (portions of) the data mart in parallel on all nodes, without using any indexes or materialized views, and without any query optimizer to choose among them. The Blink technology has thus far been incorp

Multifunctional ZnO/SiO2 Core/Shell Nanoparticles for Bioimaging and Drug Delivery Application

Semiconducting nanoparticles with luminescent properties are used as detection probes and drug carriers in in-vitro and in-vivo analysis. ZnO nanoparticles, due to its biocompatibility and low cost, have shown potential application in bioimaging and drug delivery. Thus, ZnO/SiO2 core/shell nanoparticle was synthesised by wet chemical method for fluorescent probing and drug delivery application. The synthesised core/shell nanomaterial was characterized using XRD, FTIR, UV-VIS spectroscopy, Raman spectroscopy, TEM and PL analysis. The silicon shell enhances the photoluminescence and aqueous stability of the pure ZnO nanoparticles. The porous surface of the shell acts as a carrier for sustained release of curcumin. The synthesized core/shell particle shows high cell viability, hemocompatibility and promising florescent property. [Figure not available: see fulltext.]

Investigations on Hot-wall deposited Cadmium Sulphide buffer layer for thin film solar cell

Cadmium Sulphide (CdS) thin films were deposited on to well-cleaned soda lime glass substrates using hot wall deposition technique at room temperature. The structure of CdS thin films was found to be hexagonal with < 0 0 2 > orientation and after annealing the film crystallized to < 0 0 2 >, < 1 0 1 >, < 1 0 2 >, < 1 1 2 > directions. Raman Spectroscopy confirmed the hexagonal structure with a shift at 312 cm(1). SAED pattern from the Transmission electron microscopy also confirmed the formation of hexagonal CdS. X-ray Photoelectron Spectroscopy confirmed the formation of CdS with relevant at% of Cd and S. Field emission scanning electron microscopy images revealed smooth surface of the thin film with distinctive grains. Atomic force microscopy results showed a surface roughness of 4.47 nm. Transmission spectra of the films were studied and the transparency was found to be above 80%. The optical band gap was found to be around 2.4 eV in accordance with the reported values. The results show that device quality buffer layers can be deposited using Hot-wall deposition. (C) 2018 Elsevier B.V. All rights reserved
