For instance, a history of traumatic delivery, with good apgar scores in a term infant, raises the possibility of intracranial hemorrhage. The age at onset of seizure may suggest likely etiologies. Hypoxic-ischemic encephalopathy (hie), which is the single most common cause of neonatal seizures, usually causes seizures within the first 24 hours of life. When seizures present after the first 48 hours of life, and particularly after a period of initial well-being, infection and biochemical disorders should be considered. Seizures occurring later (e.G., >10 days of life) are more likely to be related to disorders of calcium metabolism (now rare in the united states), malformation, or neonatal epilepsy syndromes, which may be benign (e.G., benign familial neonatal seizures) or severe (e.G., early infantile epileptic encephalopathy [eiee]). Multiple possible etiologies (table 56.1) may be identified in a neonate with seizures, such as hie with hypoglycemia, hypocalcemia, and/or intracranial hemorrhage, and each must be treated appropriately. A. Specific etiologies 1. Hie. This is the most common cause of neonatal seizures, accounting for over 50% of cases. Hie can be global, as in perinatal asphyxia or focal (i.E., arterial infarction). In perinatal asphyxia, the seizures occur in the context of a newborn who has a history of difficulty during labor and delivery with alterations of the fetal heart rate, decreased umbilical artery ph, and apgar score <5 at 5 minutes. There is typically early suppression of the mental status, sometimes with coma and low tone, in addition to the seizures, which are often seen within the first 12 to 24 hours.

http://projects.csail.mit.edu/courseware/?term=ideas-for-a-narrative-essay ideas for a narrative essay Risk factors for development of aki include high daily dosage, large cumulative dose (greater than 2 to 3 g), preexisting kidney dysfunction, dehydration, and concomitant use of other nephrotoxic drugs. Tubular abnormalities manifesting as hypomagnesemia and hypokalemia often occur within the first 2 weeks of treatment, followed by the overt development of aki. Three lipid-based formulations of amphotericin b have been developed in an attempt to improve efficacy and limit toxicity, particularly nephrotoxicity. Amphotericin b lipid complex, amphotericin b colloidal dispersion, and liposomal amphotericin b. The range of nephrotoxicity reported is 15% to 25% for 394  section 4  |  renal disorders these formulations. The mechanism for decreased nephrotoxicity has not been completely elucidated, but it is thought to be due to preferential delivery of amphotericin b to the site of infection, with less affinity for the kidney. 31 costs for liposomal formulations are significantly higher than for the conventional formulation. Thus, lipid-based formulations are typically recommended for individuals with risk factors for aki. Administration of iv normal saline may also attenuate nephrotoxicity associated with amphotericin b. Whether there are significant differences in nephrotoxicity between the three lipid-based formulations remains unclear. In a recent meta-analysis of eight studies evaluating the nephrotoxicity of liposomal amphotericin b compared with amphotericin b lipid complex, nephrotoxicity was generally similar. 32 however, large prospective studies comparing the incidence of nephrotoxicity among liposomal formulations are needed to definitively ascertain differences in nephrotoxicity. »» radiocontrast agents radiocontrast agents are administered during radiologic studies and are associated with a well-documented risk of contrastinduced aki (ci-aki). Although definitions have been variable in the literature, ci-aki is frequently defined as a rise in scr of at least 0. 5 mg/dl (44 μmol/l) or a 25% increase in scr within 48 hours of contrast administration. Patients at risk for developing ci-aki include patients with a gfr less than 60 ml/min (1. 0 ml/s), diabetes, dehydration, age more than 65 years, concomitant nephrotoxic drug administration, and higher dose of contrast dye. 33 the risk increases as gfr decreases and patients with ckd and another comorbidity (eg, diabetes or dehydration) are at a significantly higher risk. Contrast agents are water soluble, triiodinated, benzoic acid salts. The mechanism of nephrotoxicity is not fully understood. However, direct tubular toxicity, renal ischemia, and tubular obstruction have been implicated. 34 diatrizoate and metrizoate are ionic, high osmolar contrast agents. Iohexol, iopamidol, ioversol, and iopromide are nonionic, low osmolar agents. The incidence of nephrotoxicity with ionic and nonionic agents is similar in patients at low risk for developing aki. However, in high-risk patients, nephrotoxicity is significantly greater when high ionic, high osmolar contrast agents are used. The cost of nonionic agents is approximately 10-fold higher, which may limit their routine use to high risk patients. Therapeutic measures to decrease the incidence of ci-aki include extracellular volume expansion, limiting the amount of contrast administered, and use of nonionic contrast agents. Treatment with oral acetylcysteine has produced mixed results.

essay helping handicapped people Classify the intrinsic subtype of this breast cancer. Describe the treatment goal and management strategy for this patient’s breast cancer. Appraise the patient’s overall prognosis. Common early signs and symptoms include. Painless lump (90% of cases) that is. •• solitary •• unilateral •• solid •• hard •• irregular •• nontender stabbing or aching pain (10% of cases) as the first symptom uncommon early signs and symptoms include. Nipple discharge (3% of women and 20% of men), retraction, or dimpling •• eczema appearance of the nipple (paget carcinoma) •• prominent skin edema, redness, warmth, and induration of the underlying tissue (inflammatory carcinoma) metastatic signs and symptoms—tissues most commonly involved with metastases are lymph nodes (other than axillary or internal mammary), skin, bone, liver, lungs, and brain. The following symptoms of metastases will be present in about 10% of patients when they first seek treatment. •• bone pain •• difficulty breathing •• abdominal enlargement •• jaundice •• mental status changes while lobular carcinoma in situ (lcis) may not be a true cancer, but rather a high-risk premalignant lesion. The overwhelming majority of cases can be cured by surgery alone. Although there is no proven role for the application of cytotoxic chemotherapy, patients with hormone receptor-positive tumors may benefit from the addition of tamoxifen. 8 clinical presentation and diagnosis early detection the rationale for early detection of breast cancer is based on the clear relationship between early stage disease at diagnosis and greater probability of long-term survival. Thus, patients with tumors less than 2 cm and negative lymph nodes have a higher likelihood of being cured. Screening guidelines for early detection of breast cancer have been put forward by the american cancer society, the united states preventive services task force (uspstf), and the nci (table 89–3). All include recommendations for women at average risk, with some general statements regarding screening for high-risk women as well. Nearly 80% of all breast cancers occur in women 50 years of age or older, and regular use of screening mammography can reduce mortality from breast cancer by 20% to 40% in this age group. Controversy regarding the use of screening mammography is largely confined to women younger than 50 years. After many years of debate, three organizations recommended mammograms in this age group of women every 1 to 2 years except for the uspstf, which modified its recommendation in 2009. 9 diagnosis unless following up on abnormalities found during screening, the initial workup for women presenting with signs or symptoms (see clinical presentation and diagnosis) suggestive of breast cancer should include a careful history, physical examination of the breast, three-dimensional mammography, and possibly other imaging techniques such as magnetic resonance imaging.
