Question 26 A 75 yo man presents with a painless buy discount entocort 100mcg on line, small mass overlying his left parotid purchase entocort 100mcg line. There is a relatively high transformation rate into malignant disease so total parotidectomy with facial nerve reconstruction is recommended C. Though the tumor itself is benign, there is a slight chance it may undergo malignant transformation so superficial parotidectomy is recommended D. Superficial parotidectomy is the recommended treatment Parotid Gland Tumors- Benign 70% are benign; 70% of all salivary tumors originate in parotid Pleomorphic adenoma- most common (70%); mixed tumor with epithelial and myoepithelial elements 8. This is a highly malignant tumor with 5-year disease free survival less than 10% B. This is considered a low grade tumor and when treated with complete resection has a good prognosis C. Neoadjuvant chemoradiation should be administered first with surgery being reserved for nonresponders D. This tends to present at a slightly older age than other salivary tumors so 51 is unusual Answer 27 B. Question 28 A 75 year old man who underwent a total parotidectomy with wide resection for a malignant tumor 1 year ago presents with a new mass in his lung that is suspicious for metastatic disease. You review the pathology and operative report from his record and it states that there was perineural infiltration and skip lesions along the facial nerve. Question 29 You perform a total parotidectomy on this patient from which he seems to progress from well initially. At a 3 month follow up, he states that he experiences redness and sweating over his cheek and near his ear when he eats or even thinks about food. If the symptoms easily replicate by having him eat a lemon slice, you can consider Botox injection to see if that relieves the symptoms D. It is most likely secondary to injury and inappropriate regeneration of the auriculotemporal branch of the trigeminal nerve E. He states that he experiences nausea, occasional nonbilious emesis, and dizziness about 2 hours after he eats. If you were to check his glucose when the symptoms occur, it would most likely be high B. This usually does not improve with conservative treatment so you should anticipate converting him to a Roux-en-Y C. This is most likely due to retained antrum so you will need to consider repeat resection Answer 30 C. He experiences frequent epigastric pain after meals with subsequent bilious vomiting that does not relieve the pain. This is most likely due to retained antrum so you will need to consider repeat resection D. On postoperative day 1 he is experiencing severe abdominal pain and nonbilious emesis. You obtain imaging which is concerning for a markedly dilated bowel limb proximal to the anastomosis. You would be less likely to have this complication if you did an antecolic gastrojejunostomy C. In the chronic form (from partial obstruction) patients may develop microcytic anemia E. This picture is concerning for afferent limb obstruction- the patient needs intervention as he is high risk for duodenal stump blowout. Preoperative multiagent chemotherapy and radiation followed by resection 6 weeks after treatment B. Alpha-ketoglutarate Question 2 (of 3) The primary fuel source for small bowel is: A. Alpha-ketoglutarate Question 3 The primary fuel source for cancer cells is: A. It is thought that tube feeds with glutamine may help decrease gut translocation in patients with sepsis, trauma, etc. Question 4 During prolonged starvation the brain switches from using glucose to using: A. The brain switched from glucose to ketones after prolonged starvation Question 5 The p53 tumor suppresor gene is primarily involved in A. P53 is primarily involved in cell cycle regulation and apoptosis Question 6 Hyperacute rejection following organ transplantation is most often due to: A. New proteinuria is most consistent with renal vein thrombosis Question 9 The maximum amount of collagen in a wound occurs at: A. After that the amount of collagen stays the same but continued cross-linking improves strength Question 10 Diaphragm injuries are: A. Diaphragm injuries are more common with blunt trauma and on the left as the liver protects the right side. Question 12 You perform a laparotomy in the previous pt and find a large left sided retroperitoneal hematoma that extends above the celiac artery. Because the hematoma extends above the celiac artery a Mattox maneuver is not going to give you proper exposure.

Phytochemicals protect against oxidative stress which in turn helps in maintaining the balance between oxidants and antioxidants. Antioxidant activity is presented as the range of values for each of the food groups. To the best of our knowledge, these are the frst results of the kind in commonly consumed Indian plant foods. Although more than 8000 oxide anion, hydroxyl radical, and hydrogen peroxide (H2O2) phytochemicals have been identifed in plant foods, a large are ofen generated as byproducts of biological reactions percentage remains to be identifed. Since plant foods are ofen relatedphenoliccompounds,havemultiplebiologicalefects, consumed in one or the other cooked forms, polyphenol and including antioxidant activity. Terefore it was considered the diferences in the chemical nature of antioxidants and pertinent to study the efect of domestic processing on the phenolics, namely, simple to highly polymerized chemical natural antioxidant activity and phenolic content of com- substances present in plant foods. Available literature, mostly from other idants present in dates were water-soluble (hydrophilic). On parts of the world, indicates that diferent researchers have the other hand extraction with 50% methanol yielded the adopted diferent sampling methods to get representative highest recovery of phenolics in the same study. In another study, Al- extracting antioxidant activity and 50% methanol to estimate Farsi et al. Found that water and 80% methanol showed Vegetable for extraction whereas Nair et al. In another study, Chi- fresh food samples from local market, and fve grams of dambara Murthy et al. Keeping in view the diferences and could thus be important in combating reactive oxygen in the sampling methods used and the quantities of samples species. Hence we have used acidic, 80% methanol (with three diferent locations of the twin cities of Hyderabad and 0. Methanol extracts were also used to know the analyzed in triplicates, and the results are presented as mean efect of domestic cooking. Cooking was done ofthesampleweresubjectedtoconventional,pressure,and with the sample covered with lid except in conventional microwave methods of cooking, respectively. To estimate natural (raw) antioxidant content, the icked consumers habits of food procurement from market to frst portion of 10 or 25 g of the edible portion of the sample household. Various Antioxidant Methods in Use solvent extraction procedures have been used by diferent researchers. Tis probably is due to biological antioxidants in plant foods by a single antioxidant Oxidative Medicine and Cellular Longevity 3 method. Te exact comparison of the results obtained by dif- in methanol) was added and vortexed vigorously. Several new analytical approaches have ing physiological antioxidant capacity [29]. Food provides suggested investigating antioxidant power of food extracts on not only nutrients essential for life but also other bioactive the basis of their electron-donating ability. It has indeed been estimated based assays and ofen show excellent correlation with pheno- that a healthy diet could prevent approximately 30% of all lic contents, and they are carried out in acidic conditions; pH cancers [31]. So far, published data from other parts of values have an important efect on the reducing capacity of the world and India account only for a minor fraction of antioxidants. Terefore it was be suppressed due to protonation on antioxidant compounds, suggested to have food composition tables on antioxidant whereas in basic conditions proton dissociation of phenolic activity and polyphenolic content of commonly consumed compounds would enhance the sample reducing capacity plant foods from developing countries [32]. Soluble and hydrolysable phenolic markets of the twin cities of Hyderabad and Secundrabad contents (free phenols) were estimated as per the procedure (India). Cereals 2028622 mg/100, with areca nut showing the highest and and millets ranged 45013093 mg/100 g, highest activity was coconutwaterhavingtheleastactivities. Some of these fndings are in agreement with 1021mg/100g,withCurryleaveshavingthehighestwhereas theliteraturevaluesoffreshfruits[32]. Interestingly dry fruits had activity being found in red beet root and the lowest in carrot. Te highest activity was found in okra and the observations made by two diferent methods in fresh and lowest was in ridge gourd. Due to scanty data available in dry fruits could be validated by a common, third method.

Eventual growth of fibrous tissue in to the blood clot to close the hole in the vessel permanently order entocort 100 mcg otc. Remark: The student is advised to revise his physiology lecture note on the above topics proven entocort 100 mcg. Definition: Thrombosis is defined as the formation of a solid or semisolid mass from the constituents of the blood within the vascular system during life. These factors are called Virchows triad: A: Endothelial injury B: Stasis or turbulence of blood flow C: Blood hypercoagulability 71 A: Endothelial injury It is the most important factor in thrombus formation and by itself can lead to thrombosis. B: Turbulence or Stasis (Alterations in normal blood flow) Under physiologic conditions normal blood flow is laminar, that is, the cellular elements flow centrally in the vessel lumen separated from endothelium by slowing moving clear zone of plasma. Disrupt the laminar flow and bring platelets in to contact with the endothelium b. Retard or make a time lag in the inflow of clotting factor inhibitors and permit the build up of thrombi. A dilated left atrium is a site of stasis & a prime location of thrombus development. C: Hypercoagulablity Definition: Hypercoagulability is any alteration of the coagulation pathway that predisposes to thrombosis. Hypercoagulability is a less common cause of thrombosis & & it can be divided into: 1. Morphology of Thrombi Thrombi may develop any where in the cardiovascular system. The differences between arterial & venous thrombi are: Arterial thrombi Venous thrombi a) Arise at the site of endothelial injury a) Arise at area of stasis b) Grow in a retrograde fasion, against b) Grow in the direction of blood flow from its site of attachment. B: Embolization: The thrombus may dislodge and travel to other sites in the vasculature. Death of a tissue due to a decreased blood supply or drainage is called infarction. D: Organization and recanalization Organization refers to the ingrowth of endothelial cells, smooth muscle cells, and fibroblasts into the fibrin-rich thrombus. Organization is accompanied by the formation of capillary channels across the thrombus, re-establishing lumen continuity to some extent. The recanalization eventually converts the thrombus into a vasscularized mass of tissue which is later on incorporated as a subendothelial swelling of the vessel wall. Clinical significance of thrombi Thrombi are significant clinically because: - They cause obstruction of arteries and veins & - They are possible source of emboli. Venous Thrombosis (Phlebothrombosis) Venous thrombosis affects veins of the lower extremity in 90% of cases. Superficial venous thrombosis - Usually occurs in saphenous venous system, particularly when there are varicosities. This is because deep venous obstruction is rapidly offset or releaved by collateral bypass channels. Pregnancy & puerperal states increase coagulation factors & reduce the synthesis of antithrombotic substances. Migratory thrombophlebitis is a condition that affects various veins throughout the body & is usually of obscure aetiology, but sometimes it is associated with cancer, particularly pancreatic cancer. Arterial Thrombosis - The rapid flow of arterial blood prevents the occurrence of thrombosis unless the vessel wall is abnormal. Atheromatous plaques produce turbulence and may ulcerate & cause endothelial injury, both of which can lead to thrombosis. These thrombi may narrow or occlude the lumen of arteries such as the coronary and cerebral arteries. A thrombus develops in the atrium in patients with atrial fibrillation & dilatation superimposed on mitral stenosis. Embolism Definition:- An embolus is a detached intravascular solid, liquid or gaseous mass that is carried by blood to sites distant from its point of origin. Causes of embolism: An embolus can arise from: o Thrombus (99% of emboli arise from a thrombus. Such an embolus is called thromboembolus) o Platelets aggregates o Fragment of material from ulcerating atheromatous plaque o Fragment of a tumour o Fat globules o Bubbles of air o Amniotic fluid o Infected foreign material o Bits of bone marrow o Others. Unless otherwise specified, the term embolism should be considered to mean thromboembolism. Such an embolus is derived from a thrombus in the systemic veins or the right side of the heart. The thromboembolus will travel long with the venous return & reach the right side of the heart. Depending on the size of the embolus and on the state of pulumonary circulation, the pulmonary embolism can have the following effects: 1.
