Abstract:
AbstractIntroduction:There is currently a lack of robust evidence on the best form of packing for otological surgery. We describe the use of the absorbable gelatin sponge, a packing material that does not require removal and has the benefit of being considerably cheaper compared to other common forms of ear packing.Methods:A comparison was made of the financial cost of several forms of packing for common otological procedures. In addition, a retrospective audit of complications was undertaken of all patients in whom the absorbable gelatin sponge was used over the past three years.Results:The absorbable gelatin sponge was shown to be cheaper to purchase per unit and also more economical to use. It has been the exclusive form of packing used in 519 procedures over the past three years at the William Harvey Hospital in Ashford (UK), with very few complications noted at the follow-up review.Conclusion:We strongly advocate using the absorbable gelatin sponge, a packing material that is kinder to the patient, has similar efficacy to other forms of packing and is also much cheaper to use compared to other common forms of packing.

Abstract:
Background: A number of different nasal packing materials are available for prevention of nasal bleeding after endoscopic sinus surgery. Polyvinyl alcohol (PVA) coated nasal packing is an expandable packing for use in rhinological surgery. This innovative surf- ace treatment helps to reduce the possibility of adherence to tissue and of blood clotting within the sponge. The present study investigated the effects of PVA coated packing and non-absorbable packing with respect to pain, healing site and postoperative bleeding following endoscopic sinus surgery. Methodology: Patients between 18-80 years of age undergoing sinus surgery were enrolled. Each patient`s ethmoid cavities were randomised to receive PVA coated packing material or the standard non-absorbable sinus packs. The remaining nasal packing material was removed on the 2nd day in the clinic. We determined visual analog scale score, bleeding time and wound healing status. A single rhinologist graded postoperative endoscopic appearance. Length of follow-up was 3 months. Results: Thirty three patients were recruited. There was a significant difference in the bleeding time between the two groups, but pain and wound healing were not significantly different between the two groups. Conclusion: PVA-coated nasal packing presents comparable characteristics with traditional nasal packing.

Abstract:
AbstractBackground:Haemorrhage is the most common major complication of endoscopic sinus surgery. Post-operative absorbable or non-absorbable nasal packing can cause pain and blockage. Haemostatic powders or gels may prevent this problem. However, when based on factors in the clotting cascade, they induce an inflammatory reaction and can cause post-operative synechiae. Oxidised cellulose powder produces haemostasis without inducing synechiae formation, but has not been trialled for sinus surgery.Method:A randomised clinical trial was performed to compare cellulose powder to non-absorbable packing following sinus surgery. Participants were 50 consecutive patients undergoing sinus surgery, 47 of whom completed the study. The main outcome measures were post-operative bleeding, pain scores and synechiae formation.Results:Cellulose powder was effective at stopping bleeding, and was associated with less pain than nasal packing, with no evidence of increased synechiae formation.Conclusion:Cellulose powder appears to be a good haemostatic agent following sinus surgery. A larger trial would allow more accurate quantification of its effectiveness.

Abstract:
Background The optimal form of nasal packing after endoscopic sinus surgery (ESS) still has not been established. Although wide variations exist among sinus surgeons, the goals are adequate hemostasis, rapid healing, and patient comfort. Preliminary studies indicated that FloSeal (FS), a novel absorbable hemostatic paste used as a nasal pack, was associated with minimal postoperative discomfort and effective hemostasis. This study was designed to evaluate the effects of this agent on mucosal healing in ESS. Methods Twenty consecutive patients underwent bilateral ESS. For each patient, one ethmoid cavity was randomized to receive FS and the other received thrombin-soaked gelatin foam. The extent of granulation tissue and adhesion formation was evaluated at 6–8 weeks after surgery. Results No significant differences were observed between the FS and the thrombin-soaked gelatin foam groups with respect to the preoperative Lund-Mackay score, extent of surgery performed, or need for additional nasal packing. However, the FS group showed clear trends toward increased granulation tissue (p = 0.007) and adhesion (p = 0.006) formation. Conclusion: Absorbable hemostatic agents are associated with a high degree of patient comfort and provide hemostasis comparable with traditional techniques. Different materials may induce differential patterns of mucosal healing, potentially affecting the ultimate result of ESS.

Abstract:
OBJECT Despite the increasing application of endoscopic transsphenoidal surgery for pituitary lesions, the prognostic factors that are associated with sinonasal quality of life (QOL) and nasal morbidity are not well understood. The authors examine the predictors of sinonasal QOL and nasal morbidity in patients undergoing fully endoscopic transsphenoidal surgery. METHODS An exploratory post hoc analysis was conducted of patients who underwent endoscopic pituitary surgery and were enrolled in a prospective multicenter QOL study. End points of the study included patient-reported sinonasal QOL and objective nasal endoscopy findings. Multivariate models were developed to determine the patient and surgical factors that correlated with QOL at 2 weeks through 6 months after surgery. RESULTS This study is a retrospective review of a subgroup of patients studied in the clinical trial “Rhinological Outcomes in Endonasal Pituitary Surgery” (clinical trial no. NCT01504399, clinicaltrials.gov). Data from 100 patients who underwent fully endoscopic transsphenoidal surgery were included. Predictors of a lower postoperative sinonasal QOL at 2 weeks were use of nasal splints (p = 0.039) and female sex at the trend level (p = 0.061); at 3 months, predictors of lower QOL were the presence of sinusitis (p = 0.025), advancing age (p = 0.044), and use of absorbable nasal packing (p = 0.014). Health status (multidimensional QOL) was also predictive at 2 weeks (p = 0.001) and 3 months (p < 0.001) and was the only significant predictor of sinonasal QOL at 6 months (p < 0.001). A Kaplan-Meier analysis was performed to study time to resolution of nasal crusting, mucopurulence, and synechia as observed during nasal endoscopy after surgery. The mean time (± SEM) to absence of nasal crusting was 16.3 ± 2.1 weeks, mucopurulence was 6.2 ± 1.1 weeks, and synechia was 4.4 ± 0.5 weeks. Use of absorbable nasal packing was associated with more severe mucopurulence. CONCLUSIONS Sinonasal QOL following endoscopic pituitary surgery reaches a nadir at 2 weeks and recovers by 3 months postoperatively. Use of absorbable packing and nasal splints, while used in a minority of patients, negatively correlates with early sinonasal QOL. Sinonasal QOL and overall health status are well correlated in the postoperative period, suggesting the important influence of sinonasal QOL on the patient experience.

Abstract:
“Surgery is a profession defined by its authority to cure by means of bodily invasion. The brutality and risks of opening a living person's body have long been apparent, the benefits only slowly and haltingly worked out”, says Atul Rawande on reviewing 200 yrs. of Surgery as a specialty in NEJM. My research focuses on working out these benefits, specifically looking at reduction of scar tissue formation in ENT, Abdominal & Spine surgery. Scar tissue formation is an outcome of healing process that can be excessive due to inflammation or infection and thereby has the ability to curtail the benefits or warrant revision surgery. Multiple strategies have been tested and employed thus far and none have given favourable results without causing additional harm or economic burden in health care costs. I propose to use a hydrogel synthesized by combining Chitosan and Dextran aldehyde -Chitin is an exoskeleton extracted polymer and Dextran Aldehyde a sugar, with added noveldrugs Deferiprone and Gallium Protoporphyrin providing additional anti scaring and antibiotic properties which could potentially augment the healing properties of the gel. I have conducted 3 types of studies. There are 2 animal studies and a Phase 1 Human clinical trial. The animal studies are an abdominal surgery rat model and a spine surgery sheep model. These studies show the safety and efficacy of this chitogel-drug combination at various dosages and illustrate the healing benefits of gel-drug combination.

Abstract:
Lipid autoxidation poses a significant problem for stabilizing sensory quality, nutritional value, and chemical safety of lipid containing foods. Peroxide value and volatile carbonyls are the most measured markers to assess oxidation, but products such as epoxides and alcohols are now being identified and quantified in foods. The mechanisms and conditions under which other products form are poorly understood, particularly how lipid structure and oxidation conditions affect reaction pathways, products, and rates. This research paper aims to show how number of double bonds affects oxidation product formation, how oxidation temperature affects reaction rates and product formation and decomposition, and how open or closed packaging systems affect reaction rates.Methyl oleate and methyl linoleate were autoxidized neat and incubated at 25, 40, or 60 °C for various incubation periods. Class assays for quantification of oxidation products included the following: conjugated dienes by UV absorbance at 233 nm; peroxide value by reaction with TPP; epoxide value by reaction with diethydithiocarbamate; soluble carbonyls by reaction with 2,4-dinitrophenylhydrazine. Direct separation of oxidation products was performed using NP-HPLC with detection and quantitation by UV and Corona Charged Aerosol (CAD) detection. Alternate autoxidation products competed with the formation of hydroperoxides in both autoxidizing oleate and linoleate. Epoxides were found to be the dominant product in oleate autoxidized at 25 C, reaching a maximum value of 69.2 mmol/mol lipid, while peroxide value reached a maximum of 23.71 mmol/mol lipid. Epoxides were also found to be a major product in linoleate autoxidation reaching a maximum value of 357.5 mmol/mol lipid at 25 C, while peroxide value reached a maximum of 357.1 mmol/mol lipid. For both oxidized oleate and linoleate, rate of epoxide formation competed with that of hydroperoxides, demonstrating that alternate reactions are active and important in directing the reaction rates and product distributions of autoxidizing lipids.

Abstract:
Antioxidant activity of fruits is gaining wide interest among consumers due to its importance in counteracting oxidative stress, free radicals and preventing DNA damage. Oxygen radical absorbance capacity (ORAC) assay is one of the commonly used assays to measure the antioxidant activity, which is based on hydrogen atom transfer mechanism. Furocoumarins present in grapefruit are reported to have antiproliferative activity, induce GST activity, inhibit biofilm formation and increase bioavailability of drugs. In the present project ORAC values were measured of Star Ruby grapefruit undergone ethylene degreening treatment, cold storage and temperature conditioning treatment, and modified atmosphere packaging which were stored at different temperatures for prolonged period. In addition, furocoumarins were quantified in Star Ruby grapefruits from cold storage and conditioning experiment conducted in Israel. Conditioning treatment is practiced prior cold storage to reduce chilling injury in grapefruits during cold storage for prolonged period. Levels of 6,7-dihyrdoxy bergamottin decreased during storage period in all three treatments.
