2018, Louisiana State University Health Sciences Center New Orleans, Sancho's review: "Zetia generic (Ezetimibe) 10 mg. Trusted online Zetia.".

Children and adults with a history of large local reactions to stings are at relatively high risk for developing anaphylaxis buy cheap zetia 10mg cholesterol medication best time to take, and venom immunotherapy in these patients is required B purchase 10 mg zetia amex cholesterol grapefruit. Although standard venom immunotherapy is generally well tolerated, it is only 40% to 50% effective in completely preventing systemic aller- gic reactions to stings C. In a patient who has had a single anaphylactic reaction to a sting and whose skin test is positive, immunotherapy is indicated D. In a patient receiving immunotherapy, the skin test usually becomes negative within the first 4 to 6 months; failure to do so may indicate a lack of response to the treatment Key Concept/Objective: To understand the indications for and typical outcomes of venom immunotherapy Patients with anaphylactic reactions to Hymenoptera stings should be educated about the risk of future reactions and about avoiding exposure. These patients should also under- stand the need for an epinephrine kit, and in most cases they should be evaluated by an allergist. The indications for venom immunotherapy are a history of a systemic allergic reaction to a sting and a positive venom skin test. In patients with these indications, the risk of anaphylaxis after subsequent stings approaches 50%. On the other hand, children and adults with a history of large local reactions have only a 10% chance of developing anaphylaxis after subsequent stings; in these patients, immunotherapy is an option (which many patients choose) but is not required. Standard immunotherapy is quite effective; it completely prevents subsequent systemic allergic reactions in 85% to 98% of patients. In the initial weeks of treatment, patients may develop a systemic allergic reaction, which is usually mild. Skin-test results generally remain unchanged during the first 2 to 3 years of treatment but usually decline after 4 to 6 years. The risk of life-threatening systemic aller- gic reactions occurring after 5 years of immunotherapy is low. Currently, it is recom- mended that immunotherapy be continued for an indefinite period. The patient has a 3-month history of diarrhea, post- prandial nausea and vomiting, and weight loss. There is no specific food that he can relate to his symp- toms. A complete blood count reveals anemia and eosinophilia. Small bowel biopsy reveals eosinophilic infiltration without vasculitis. Which of the following is the most likely diagnosis for this patient? Immediate gastrointestinal hypersensitivity 22 BOARD REVIEW Key Concept/Objective: To be able to recognize allergic eosinophilic gastroenteropathy Allergic eosinophilic gastroenteropathy is a disorder characterized by infiltration of the gastric or intestinal walls with eosinophils; absence of vasculitis; and, frequently, peripher- al blood eosinophilia. The symptoms include postprandial nausea and vomiting, abdomi- nal pain, diarrhea, and, occasionally, steatorrhea. Young infants have failure to thrive, and adults have weight loss. There appears to be a subset of patients with allergic eosinophilic gastroenteritis who have symptoms secondary to food. These patients generally have the mucosal form of this disease, with IgE-staining cells in jejunal tissue, elevated IgE in duo- denal fluids, atopic disease, elevated serum IgE concentrations, positive prick skin tests to a variety of foods and inhalants, peripheral blood eosinophilia, iron deficiency anemia, and hypoalbuminemia. The diagnosis of eosinophilic gastroenteropathy is based on an appropriate history and a GI biopsy demonstrating a characteristic eosinophilic infiltra- tion. The oral allergy syndrome is a form of contact urticaria that is confined almost ex- clusively to the oropharynx and rarely involves other target organs. Patients with imme- diate GI hypersensitivity present with GI symptoms after the ingestion of a specific food. Churg-Strauss syndrome is a form of small-vessel vasculitis; patients present with asthma, sinusitis, and eosinophilia. A 3-year-old boy is brought to your office by his mother, who relates that her son was diagnosed as hav- ing peanut hypersensitivity 1 year ago.

Testing in this patient is not indicated discount 10mg zetia with visa average cholesterol japan; even if she tests negative for an inherited cancer-predisposing mutation in the BRCA1 or BRCA2 gene generic zetia 10mg visa raise good cholesterol foods, she may still have a mutation in another gene that predisposes to breast cancer E. It is important to 3 ENDOCRINOLOGY 13 note, however, that BRCA1 and BRCA2 mutations cause only a small increase in the over- all incidence of breast cancer. In patients undergoing genetic testing because of a sugges- tive family history, it is highly recommended that there be pretest and posttest counseling. If a cancer-predisposing mutation is identified, BRCA1 or BRCA2 mutation analysis is more informative for unaffected relatives. However, depending on the type of analysis done, mutations of uncertain clinical significance may be identified; such findings are dif- ficult (at best) to interpret. If a cancer-predisposing mutation is found in the mother, the patient should be counseled not to desist from rigorous screening for breast cancer. Furthermore, in individuals from high-risk ethnic groups, such as Ashkenazi Jews, it might be reasonable to test for all the cancer-predisposing mutations known to be com- mon in that population, even if a single cancer-predisposing mutation had already been identified in an affected family member. Unfortunately, there are no unique interventions of proven benefit for those individuals in whom a genetic susceptibility to breast cancer is found, beyond the routine mammography screening recommended for women of average risk beginning at 40 or 50 years of age. Additional recommendations for women in high- er risk categories are made on the basis of presumptive benefit and have not yet been sup- ported in clinical studies. A 32-year-old man presents to your clinic for a routine follow-up visit. He complains of intermittent episodes of shaking, palpitations, sweating, and anxiety. He has a friend who is a hypoglycemic and is on a special diet, and he wonders if he too may have low blood sugar. While in the waiting room, he develops symptoms, and your nurse obtains a blood glucose level. What is the most appropriate step to take next in the workup of this patient? Admit the patient to the hospital for a prolonged fast B. Send the patient for an endoscopic ultrasound, looking for insulinoma C. Measure the insulin and C-peptide levels, assess for insulin antibodies, and have the patient follow up in 1 month D. Refer the patient directly to surgery for resection of presumed insulinoma E. No further workup for hypoglycemic disorder is necessary at this time Key Concept/Objective: To understand that a normal serum glucose concentration in a sympto- matic patient rules out hypoglycemic disorders A normal serum glucose concentration, reliably obtained during the occurrence of spon- taneous symptoms, eliminates the possibility of a hypoglycemic disorder; no further eval- uation for hypoglycemia is required. Glucometer measurements made by the patient dur- ing the occurrence of symptoms often are unreliable, because nondiabetic patients usual- ly are not experienced in this technique and the measurements are obtained under adverse circumstances. However, a reliably measured capillary glucose level that is in the normal range eliminates the possibility of hypoglycemia as the cause of symptoms. Normoglycemia during symptoms cannot be ascribed to spontaneous recovery from pre- vious hypoglycemia. In fact, the reverse is true; symptoms ease before the serum glucose achieves a normal level. A 53-year-old woman presents to your clinic complaining of transient episodes of diaphoresis, asthenia, near syncope, and clouding of thought process; she has had these symptoms for several months. These episodes most commonly occur several hours after she eats. She has no other significant medical histo- ry and takes no medications. A prolonged fast is begun, during which the patient becomes symptomatic. Her serum glucose concentration at the time is 43 mg/dl. The insulin level is elevated, and no insulin antibodies are present. The C-peptide level is high, and tests for the use of sulfonylureas and meglitinides are negative.
