Toxicity 3 Increased risk of bleeding complications in the setting of thrombocytopenia great depression brief definition buy wellbutrin 300 mg free shipping. Toxicity 4 Gastrointestinal toxicity with diarrhea depression symptoms emotional numbness generic 300 mg wellbutrin visa, nausea/vomiting anxiety keeping me from sleeping wellbutrin 300mg with visa, abdominal pain, and anorexia. Distribution Widely distributed to all tissues with a 50-fold higher volume of distribution than cisplatin. Metabolism Oxaliplatin undergoes extensive nonenzymatic conversion to its active cytotoxic species. As observed with cisplatin, oxaliplatin undergoes aquation reaction in the presence of low concentrations of chloride. Use with caution in patients with abnormal renal function, especially when CrCl <20 mL/min. Baseline creatinine clearance should be obtained, and renal status should be closely monitored during treatment. Careful neurologic evaluation should be performed before starting therapy and at the beginning of each cycle as the dose-limiting toxicity of oxaliplatin is neurotoxicity. Caution patients to avoid exposure to cold following drug administration, which can trigger and/or worsen acute neurotoxicity. Calcium/magnesium infusions (1 gm calcium gluconate/1 gm agnesium sulfate) prior to and at the completion of the oxaliplatin infusion can be used to reduce the incidence of acute neurotoxicity. There is no evidence that these infusions impair the clinical activity of oxaliplatin. May lengthen oxaliplatin infusion from 2 to up to 4 hours to reduce the incidence of acute neurotoxicity. Anaphylactic reactions to oxaliplatin have been reported and may occur within minutes of drug administration. Chronic toxicity is dose-dependent with a 15% and >50% risk of impairment in proprioception and neurosensory function at cumulative doses of 850 and 1200 mg/m2, respectively. Chemotherapeutic and Biologic Drugs 337 O Toxicity 5 Allergic reactions with facial flushing, rash, urticaria, and less frequently, bronchospasm and hypotension. Toxicity 6 Hepatotoxicity with sinusoidal injury resulting in portal hypertension, ascites, splenomegaly, thrombocytopenia, and varices. Results in enhanced drug efflux with decreased intracellular accumulation of drug. Chemotherapeutic and Biologic Drugs 339 P Distribution Distributes widely to all body tissues, including third-space fluid collections such as ascites. Terminal elimination half-life ranges from 9 to 50 hours depending on the schedule of administration. Drug Interaction 4 Cisplatin, carboplatin-Myelosuppression is greater when platinum compound is administered before paclitaxel. P Drug Interaction 5 Cyclophosphamide-Myelosuppression is greater when cyclophosphamide is administered before paclitaxel. Drug Interaction 6 Doxorubicin-Paclitaxel reduces the plasma clearance of doxorubicin by about 30%, resulting in increased severity of myelosuppression. Patients with abnormal liver function are at significantly higher risk for toxicity. Use with caution in patients with prior history of diabetes mellitus and chronic alcoholism or prior therapy with known neurotoxic agents such as cisplatin.

Because of the content of Hematology Answers 235 Hb A depression symptoms nih purchase wellbutrin 300 mg free shipping, erythrocytes only sickle at low oxygen tension and symptoms are much milder than in sickle cell disease depression definition icd purchase wellbutrin 300mg with amex. Hb F does not react with hemoglobin S anxiety essential oils order 300mg wellbutrin fast delivery, so that patients who have Hb S and large amounts of Hb F as occurs kindling depression definition generic 300 mg wellbutrin free shipping, in newborns with sickle cell disease, are asymptomatic. Clinically, sickle cell disease is characterized by the triad of chronic hemolytic anemia, vascular occlusion, and vulnerability to infection. The severe chronic hemolytic anemia leads to chronic hyperbilirubinemia (jaundice), which leads to pigmented gallstones. Vascular occlusion results in leg ulcers, renal papillary necrosis, and multiple infarcts, which may cause severe bone pain. Repeated splenic infarcts cause progressive fibrosis and splenic atrophy (autoinfarction). Rather than hypersplenism, most adults have a small, functionless, fibrotic spleen. The lack of splenic function along with defects in the alternate complement pathway predispose to infections such as Salmonella osteomyelitis and pneumococcal infections. The vasoocclusive disease also leads to painful crises, hand-foot syndrome in children (consisting of the typical triad of fever, pallor, and symmetric swelling of hands and feet), and infarctive crises. In patients not having yet undergone splenic autoinfarction (usually children), massive splenic sequestration (sequestration crisis) may lead to rapid splenic enlargement, hypovolemia, and shock. Patients with sickle cell disease have a normocytic anemia with a corrected reticulocyte count of greater than 3%. Hydroxyurea has recently been approved for the treatment of sickle cell disease because it increases the synthesis of hemoglobin F thus reducing the, severity of the disease. The test is based on the fact that erythrocytes with a large proportion of hemoglobin S sickle in solutions of low oxygen content. Spherocytes lyse at a higher concentration of salt than do normal cells, thus causing an increased osmotic fragility. The Schilling test, which measures intestinal absorption of vitamin B12 with and without intrinsic factor, is used to diagnose decreased vitamin B12 caused by pernicious anemia, which is characterized by a lack of intrinsic factor. Therefore, thalassemias are associated with a relative excess production of non-globin chains, while thalassemias are associated with a relative excess production of -globin chains. Most of the thalassemias result from deletions of one or more of the total of four -globin genes, while thalassemias result from point mutations involving the -globin gene. In contrast, deletion of only one gene on a chromosome (- /) is called thal 2 and is found in Africans. There are two possibilities for deletion of two genes: the deletions may be on the same chromosome (- -/, which is called the cis type) or the deletions may be on different chromosomes (-/-, which is called the trans type). The former, which is also called heterozygous thal 1, is more common in Asians, while the latter, which is also called thal 2, is more common in Africans. Clinically this is quite important because the off- Hematology Answers 237 spring of parents with the trans deletions cannot develop H disease or hydrops. This name results from the fact that excess chains postnatally form aggregates of tetramers, which are called hemoglobin H. The most severe form of thalassemia, hydrops fetalis, results from deletion of all four alpha genes (- -/- -). In patients with thalassemia, a deficiency of -globins causes a deficiency of hemoglobins that have -globin chains, and at the same time there is an increase in hemoglobins that do not have -globin chains (due to the excess chains present). Because of the need for repeated transfusions, over time these patients develop iron accumulation that leads to the formation of hemochromatosis. Indeed, congestive heart failure due to iron deposition within the heart is the major cause of death. Individuals with thal major have increased reticulocytes, increased hemoglobin A2, and markedly increased hemoglobin F (90%). In these patients, increased chains produce intramedullary destruction ("ineffective erythropoiesis"). The resultant increased red marrow produces a "crew-cut" x-ray appearance of the skull and enlarges the maxilla. Complement is normally activated by acidotic states, such as occur with exercise or sleep.

Clotted central catheters producing this syndrome should be withdrawn, and anticoagulation therapy initiated. Most commonly seen in pts with lung or breast cancers, leukemias, or lymphomas; pericardial tamponade may also develop as a late complication of mediastinal radiation therapy. Echocardiography is diagnostic; pericardiocentesis may show serous or bloody exudate, and cytology usually shows malignant cells. Pts usually present with nonspecific symptoms: fatigue, anorexia, constipation, weakness. Hypoalbuminemia associated with malignancy may make symptoms worse for any given serum calcium level because more calcium will be free rather than protein bound. When serum sodium falls to 115 meq/L, pts may experience anorexia, depression, lethargy, irritability, confusion, weakness, and personality changes. If the patient has mental status changes with sodium levels 115 meq/L, normal saline infusion plus furosemide to increase free water clearance may provide more rapid improvement.
