Neurosarcoidosis: An Illustrative Case and Review of Perioperative Considerations  [PDF]
Vivek Arora, Srilatha Mallu
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.24038
Abstract: Sarcoidosis is a multisystem inflammatory granulomatous disease of unknown etiology. Neurosarcoidosis (NS) is a rare but potentially devastating manifestation of sarcoidosis, with a prevalence of approximately 5% in patients with systemic sarcoidosis. Due to the possible involvement of any part of the nervous system, a myriad of neurological manifestations can occur. Clinical features resulting from involvement of the hypothalmo-pituitary axis and cranial nerves, in particular, cranial nerve VII are the more common presentations of this condition. Medical therapy with corticosteroids is the mainstay of treatment and providing tissue for diagnosis remains the principal indication for surgery. Therapeutically, neurosurgery is indicated only for life-threatening complications. We describe the clinical case of a patient with fatally progressive NS who had multiple anesthetic exposures. This case highlights the perioperative considerations of NS and its anesthetic implications.
Early discharge after major gynaecological surgery: advantages of fast track surgery  [PDF]
Jonathan Carter, Shannon Philp, Vivek Arora
Open Journal of Obstetrics and Gynecology (OJOG) , 2011, DOI: 10.4236/ojog.2011.11001
Abstract: Introduction: Fast Track Surgery (FTS) programs have been adopted by many specialties with documented improved patient outcomes and reduced length of stay (LOS). Methods: We initiated a FTS program in January 2008 and present our experience up to and including November 2010 on patients whose LOS was 2 days. Results: During the study period 242 patients had a laparotomy performed. Overall 54(22.3%) patients were discharged on day 2. In the first year of initiating our FTS program 10% were discharged on day 2, 25% in year 2 and 31% in year 3. Twenty-two patients (41%) had malignant pathology and of these, 16 (73%) had local or regional spread and 6 (27%) had distant spread. Forty patients (74%) had vertical midline incisions (VMI) performed. Surgery was classified as complex in 40 cases (74%) and 6 (11%) patients underwent staging lymph node dissection. Average patient BMI was 26.1 with 44% of patients considered overweight or obese. There were no intraoperative complications recorded. When compared to 188 patients whose LOS was greater than 2 days, the early discharge cohort were more likely to have benign pathology, more likely to be younger, to have a transverse incision, to have received COX II inhibitors, to have a lower net haemoglobin (Hb) change and to tolerate early oral feeding. Conclusions: Increased clinical experience with FTS enables over 31% patients undergoing laparotomy to be safely discharged on day 2 without an increase in the read-mission rate or morbidity.
Fast Track Gynaecologic Surgery in the Overweight and Obese Patient  [PDF]
Jonathan Carter, Shannon Philp, Vivek Arora
International Journal of Clinical Medicine (IJCM) , 2010, DOI: 10.4236/ijcm.2010.12011
Abstract: Introduction: To review the outcomes of overweight and obese patients undergoing laparotomy and managed with a Fast Track Surgical (FTS) protocol. Methods: Between January 2008 and May 2010 patients having a laparotomy and managed on a FTS protocol were identified. They were compared to patients with a normal body mass index (BMI). Data was collected in a real time fashion and analysis undertaken in a retrospective fashion. Results: 194 patients were identified, 94 (48.4%) classified as normal BMI, 51 (26.3%) as overweight and 49 (25.3%) as obese. A vertical midline incision was performed in 170 (88%) patients. When comparing the group of overweight/obese patients (n = 100) to those with a normal BMI (n = 94) there was no significant difference in the number of benign or malignant pathologies, FIGO stage, age, insurance status, complexity of surgery, operation duration, blood loss, haemoglobin change, or need for transfusion. The proportion of patients successfully fast tracked and able to tolerate early oral feeding was similar. Patients classified as overweight or obese were significantly more likely to have a poorer performance status, have un¬dergone vertical midline incision and to have had COX II inhibitors withheld. The median length of stay (LOS) was 3 days for the patients with a normal BMI and also 3 days for those overweight or obese. Conclusions: Overweight and obese patients undergoing a fast track surgical protocol after laparotomy for gynaecological surgery have similar out comes when compared to patients of normal body mass index.

FORMULATION AND EVALUATION OF EFFERVESCENT FLOATING TABLET OF AMLODIPINE BESILATE WITH NATURAL POLYMER CHITOSAN
Dubey Vivek,Arora Vandana
Journal of Pharmaceutical and Scientific Innovation , 2012,
Abstract: Amlodipine Besilate effervescent floating tablets were developed in nine different formulations (F1 to F9) by employing natural polymer (Chitosan) and some other different grades of polymers and effervescent agents such as sodium bicarbonate and citric acid. Direct compression was the technique used for preparing tablets. The formulations were evaluated for various physical parameters, buoyancy studies, dissolution parameters and drug released mechanisms. F5 formulation showed maximum floating time of 12 hours and gave slow and maximum drug release of amlodipine Besilate spread over 12 hours. So the composition of the batch 5 should be optimized, to achieve the goal of formulation and evaluation of effervescent floating tablet of amlodipine Besilate.
Myoconjunctival enucleation for enhanced implant motility. result of a randomised prospective study.
Yadava Usha,Sachdeva Pankaj,Arora Vivek
Indian Journal of Ophthalmology , 2004,
Abstract: PURPOSE: Implant motility and cosmetic appearance of the eye after enucleation have remained major considerations whenever mycoconjunctival enucleation is planned. Despite major advances in surgical technique and the availability of a variety of implant materials and shapes, there is lack of consensus on the best material and type of implant. This study was conducted to compare routine and myoconjunctival techniques of enucleation in terms of motility index. METHODS: Thirty consecutive patients scheduled for enucleation for non-malignant indications were randomly assigned to one of the two groups- routine and myoconjunctival techniques. The postoperative results were compared for the motility of implant and the complications. RESULTS: The two techniques showed no difference in rates of complications, but implant motility was significantly better with the myoconjunctival technique. Implant extrusion or migration was not seen. CONCLUSION: We recommend the use of myoconjunctival enucleation for enhanced motility and cosmesis.

HYDRODYNAMICALLY BALANCED SYSTEMS (HBS): INNOVATIVE APPROACH OF GASTRO RETENTION: A REVIEW
Dubey Vivek,Arora Vandana,Singh Amit kumar
Journal of Pharmaceutical and Scientific Innovation , 2012,
Abstract: The objective of writing this review on hydrodynamically balanced systems (HBS) was collection of the recent literature. The design of hydrodynamically balanced drug delivery system is base on prolong GI residence time of drug in an area of the GI tract to maximize drug reaching its absorption. Gastrointestinal transit time of orally administered dosage forms are controlled by using gastro retentive drug delivery systems (GRDDS). Need for GRDDS a controlled drug delivery system with prolonged residence time in the stomach. Floating drug delivery systems is one of the important approaches to achieve gastric retention to obtain sufficient drug bioavailability. This delivery system is desirable for drugs with an absorption window in the stomach or in the upper small intestine.
ROLE OF NATURAL POLYMERS USED IN FLOATING DRUG DELIVERY SYSTEM
Singh Amit Kumar,Dubey Vivek,Arora Vandana
Journal of Pharmaceutical and Scientific Innovation , 2012,
Abstract: Floating drug delivery system is the form of gastro-retentive drug delivery system that controls the kinetic release rate of a drug to a specific site for its pharmacological action. These are achieved by use of various polymeric substance including natural polymers such as Guar Gum, Xanthan Gum, Gellan Gum etc. This delivery system prolongs the retention time of the drug in the stomach as compared to conventional dosage forms. The present article highlights the use of polymers for the formulation of the floating drug delivery system especially with natural polymers.
Fast and accurate sentiment classification using an enhanced Naive Bayes model
Vivek Narayanan,Ishan Arora,Arjun Bhatia
Computer Science , 2013, DOI: 10.1007/978-3-642-41278-3_24
Abstract: We have explored different methods of improving the accuracy of a Naive Bayes classifier for sentiment analysis. We observed that a combination of methods like negation handling, word n-grams and feature selection by mutual information results in a significant improvement in accuracy. This implies that a highly accurate and fast sentiment classifier can be built using a simple Naive Bayes model that has linear training and testing time complexities. We achieved an accuracy of 88.80% on the popular IMDB movie reviews dataset.
