A useful diagnostic and therapeutic maneuver in this situation is to observe the results of water restriction. Neurologic symptoms secondary to osmotic swelling of the brain are much more common when hyponatremia develops rapidly in menstruant women and prepubescent children. These histologic findings may occur in any part of the brain but are more common in the central areas of the pons. The symptoms of osmotic demyelinating syndrome often occur several days after too-rapid hyponatremia correction and include behavioral disturbances, fluctuating levels of consciousness, ataxia, pseudo-bulbar palsy, difficulty in speaking, and other varying features. In non-fatal cases, the recovery is slow, often taking weeks, and recovery may not be complete with residual sequelae. The rate and magnitude of this correction can be considered conveniently as a two-step process: acute correction of symptomatic hyponatremia and chronic correction of asymptomatic or residual hyponatremia. Although the development of osmotic demyelination syndrome is quite rare, failure to correct symptomatic hyponatremia is associated with unacceptable morbidity and mortality rates. In volume-contracted states, the treatment of choice is to raise the serum sodium concentration by 10 mEq/L or to levels of 120 to 125 mEq/L over a 6-hour interval by administering hypertonic 3 to 5% saline. As was discussed, elevating serum sodium too quickly to values more than 125 mEq/L may be hazardous. Because the desired effect is to correct total body water osmolality, the amount of sodium administered must be sufficient to raise total body water osmolality to approximately 250 mOsm/kg H2 O, that is, to approximately twice the desired serum sodium concentration. Because 60% of body weight is water, the formula allows an estimate of the amount of sodium required to raise total body water osmolality to 250 mOsm/kg H2 O. However, if one cannot remember this formula, a useful practice is to administer 250 mL of either 3 or 5% saline over 4 to 6 hours. This will usually raise the serum sodium concentration by 10 to 15 mEq/L and abate the neurologic symptoms. Once the acute corrective phase of hyponatremia is complete, one can initiate the principle of chronic correction of hyponatremia. The most important aspect in managing asymptomatic, non-volume-depleted hyponatremia is to restrict electrolyte-free water intake. If water intake is restricted to less than 1 L/d, the serum sodium concentration will rise regardless of its cause. Because this approach is clinically unacceptably slow in certain patients, an alternative is to use normal saline in combination with a loop diuretic. Thus, one must use a loop diuretic with intravenous saline if this approach is taken. However, both these drugs may have complications and should only be used if the patient cannot adequately comply with water restriction and high dietary salt intake. A hypertonic disorder is one in which the ratio of solutes to water in total body water is increased. Hypernatremia develops whenever water intake is less than the sum of renal and extrarenal water losses; in chronic hypertonic states, net water balance may be zero. The most common causes of clinically significant hypernatremia occur as a consequence of three pathogenic mechanisms: impaired thirst, solute or osmotic diuresis, excessive losses of water, either through the kidneys or extrarenally, and combinations of these derangements. These disorders are grouped in Table 102-10 according to the primary pathogenic mechanism. These disorders rarely cause significant hypernatremia and are not discussed further. This problem occurs in patients who are comatose or who are otherwise unable to communicate thirst. Combined Disorders Coma plus hypertonic nasogastric feeding changes in effective body water osmolality, hypernatremia due to inadequate water intake is rare in conscious patients allowed free access to water. Finally, "essential hypernatremia" is characterized by a slightly elevated serum sodium level that occurs in the conscious state. The defect in patients with essential hypernatremia appears to be an insensitivity of thirst centers and osmoreceptors to osmotic stimuli.
Jaundice may occur in patients with hemolytic anemias of all types women's health birth control methods order premarin no prescription, megaloblastic anemia from either folate or vitamin B12 deficiency menopause back pain premarin 0.625 mg amex, iron-deficiency anemia women's health & family services purchase premarin with a mastercard, sideroblastic anemia, and polycythemia vera. With these disorders, bilirubin concentration does not generally exceed 4 to 5 mg/dL. Jaundice may follow massive transfusion, because the shortened lifespan of transfused erythrocytes leads to excessive bilirubin production. Patients who have suffered major trauma may also develop hyperbilirubinemia as a result of resorption of hematomas as well as from blood transfusions. Each of these disorders involves excessive delivery of unconjugated bilirubin to the liver. Consequently, indirect bilirubin concentration in serum is increased; other biochemical markers of liver function are normal. The antituberculous agent rifampin has been shown competitively to inhibit bilirubin uptake by hepatocytes and may produce hyperbilirubinemia by this mechanism. Three familial disorders of unconjugated hyperbilirubinemia are attributable to diminished bilirubin conjugation. Serum bilirubin may rise two to threefold with fasting or dehydration but is generally below 4 mg/dL. Fasting increases the plasma concentration of unconjugated, indirect-reacting bilirubin, owing primarily to a decrease in hepatic bilirubin clearance (so-called fasting hyperbilirubinemia). Both dietary composition and total caloric intake are important; a normocaloric but lipid-free diet produces a response similar to that observed with complete fasting, and the effect of complete fasting is reversed by feeding small amounts of lipid. In each of these syndromes, the direct bilirubin level is elevated, but standard liver function tests are otherwise normal. In contrast to isolated disorders of bilirubin metabolism, icteric liver disease is characterized by an increase in serum bilirubin concentration in association with abnormalities in other standard liver function tests. Although an accurate diagnosis is possible in most patients based on clinical findings and biochemical studies (see later), certain hepatic disorders associated with cholestasis as their major manifestation may cause diagnostic confusion. These include infiltrative disorders, disorders that particularly affect the intrahepatic biliary tree, and certain other inflammatory or neoplastic conditions (see Table 146-1 and Chapters 152, 153, 156, and 157. Episodes of cholestasis last from days to months and are separated by asymptomatic periods with normal biochemical hepatic function. A single gene responsible both for benign recurrent cholestasis and one particular form of progressive cholestasis in infants has recently been identified; the function of this gene is under study. Postoperative jaundice is multifactorial in origin, with both increased bilirubin production. Hyperbilirubinemia is the most prominent biochemical manifestation and may be accompanied by a severalfold elevation of alkaline phosphatase or gamma-glutamyl transpeptidase. Aminotransferases are minimally elevated, and synthetic function is typically normal. The differential diagnosis includes biliary obstruction or liver disease due to shock, anesthetic injury, or post-transfusion hepatitis. Postoperative jaundice in the liver transplant patient presents a special problem, because the differential diagnosis also includes liver injury during organ preservation, rejection, and lymphoproliferative disorders. Postoperative jaundice per se does not pose a threat to the patient and typically resolves in 1 to 2 weeks as the overall condition of the patient improves. Jaundice in pregnancy may present as a generally self-limited disorder of the first trimester, as intrahepatic cholestasis or as acute fatty liver, or in association with pre-eclampsia in the third trimester (see Chapter 152). Obstruction of the biliary tree can be caused by gallstones, neoplasms, inflammatory disorders, or extrinsic compression (see Chapters 153, 156, and 157). The currently available tests for imaging the biliary tree represent a major advance and permit a definitive diagnosis in virtually all patients. However, if these tests are employed in an indiscriminate or redundant fashion, the patient is exposed to unnecessary discomfort, risk, and expense. The rational selection of these tests is based on the initial differential diagnosis and the likelihood that further evaluation will yield beneficial information. The distinction between liver disease and extrahepatic obstruction is generally the most important aspect of the differential diagnosis (Table 146-3). Fever, rigors, and pain in the right upper abdominal quadrant suggest cholangitis and hence biliary obstruction, as do past biliary surgery or an abdominal mass. Certain causes of jaundice such as gallstone disease and malignant neoplasm are more common in the elderly.

Diagnostic Criteria for Diabetes Mellitusa (3) Diagnostic Criteria Symptoms of diabetes (polyuria, polydipsia, unexplained weight loss) plus casual plasma glucose concentration 200 mg/dL Fasting plasma glucose concentration 126 mg/dL or or 2-hour postchallenge glucose concentration 200 mg/dL during a 75-g oral glucose tolerance test aOne of the 3 criteria listed is sufficient to establish the diagnosis of diabetes mellitus. These assessments should be confirmed by repeated testing on a subsequent day in the absence of unequivocal hyperglycemia. Diagnostic Criteria for Gestational Diabetes Mellitus Using a 75-g Oral Glucose Tolerance Testa (2) State at Plasma Glucose Measurement Fasting 1-hour postglucose administration 2-hour postglucose administration aTwo Plasma Glucose Concentration, mg/dL >95 >180 >155 or more of the listed venous plasma glucose concentrations must be met or exceeded for a positive diagnosis. The test should be performed after an overnight fast of 8 to 14 hours and after at least 3 days of unrestricted diet (ie, 150 g carbohydrate per day) and unlimited physical activity. Overview Prediabetes is the term that describes those metabolic states that occur when blood glucose levels are elevated but remain below levels that are established for the clinical diagnosis of diabetes mellitus. Prediabetes includes states of impaired fasting glucose or impaired glucose tolerance. Ethnic minorities in the United States are disproportionately affected by diabetes mellitus; however, once impaired glucose tolerance develops, ethnic background does not contribute further to the progression of diabetes (1). Results from epidemiologic studies show that hyperglycemia is strongly associated with the subsequent development of cardiovascular disease and that patients with impaired glucose tolerance frequently have increased cardiovascular risk factors (3-5). Results from epidemiologic studies also show that postprandial hyperglycemia is a strong independent risk factor for cardiovascular disease (3). Clinically significant cardiovascular disease may develop years before the clinical onset of diabetes mellitus (3-5). When current glycemic goals are achieved early in the progression of the disease, -cell function is preserved (6), and the patient gains residual long-term benefits in reducing vascular complications (7). The 2-hour oral glucose tolerance test is more sensitive for diagnosing prediabetes than the fasting plasma glucose test (8), and it is the recommended screening method for this condition (9). However, because performing the oral glucose tolerance test is not always practical in an ambulatory care setting, the fasting plasma glucose test may be used to identify patients with impaired fasting glucose. Some patients with glucose intolerance will be missed by the fasting plasma glucose test because it is less sensitive than the 2-hour oral glucose tolerance test.
The clinical signs and symptoms of hypereosinophilic syndrome can be heterogeneous because of the diversity of potential organ involvement breast cancer 74 seconds discount premarin 0.625mg amex. One of the most serious and more frequent complications in this disorder is cardiac disease secondary to menstrual vs pregnancy order premarin 0.625mg free shipping endomyocardial thrombosis and fibrosis women's health clinic ottawa hospital cheap premarin uk. Mitral and tricuspid regurgitation may result from progressive fibrotic damage to the chordae tendineae, and heart failure can develop from valvular incompetence and endomyocardial fibrosis. Cardiac involvement in hypereosinophilic syndrome, which may require surgical valve replacement, has developed in association with eosinophilias of other recognized etiologies, occasionally including parasitic infections. Neurologic involvement can take three forms: embolic disease originating from the heart, diffuse encephalopathy, and peripheral neuropathy, especially mononeuritis multiplex. Other organ systems that can be involved include the skin, liver, spleen, gastrointestinal tract, and lungs. For patients with prominent organ involvement, mortality without therapy is about 75% after 3 years. Therapy is aimed at suppressing eosinophilia and is initiated with corticosteroids, to which about one third of patients will respond. In those unresponsive to corticosteroids, hydroxyurea and interferon-alpha have also proved beneficial. Eosinophilia may accompany chronic myelogenous leukemia (see Chapter 176), often with basophilia, and some subtypes of acute myelogenous leukemia (see Chapter 177), but it is uncommon with acute lymphoblastic leukemia (see Chapter 177). A small proportion of patients with carcinomas, especially of mucin-producing epithelial cell origin, have associated blood eosinophilia. In addition to the neoplastic involvement of skin, a number of cutaneous diseases can be associated with increased blood eosinophils, including scabies (see Chapter 435), bullous pemphigoid (see Chapter 522), and two diseases associated with pregnancy: herpes gestationis and the syndrome of pruritic urticarial papules and plaques of pregnancy. In episodic angioedema with eosinophilia (see Chapter 273), recurrences are marked by blood eosinophilia and prominent angioedema, at times with significant weight gain from fluid retention, and less frequently by fever. Blood eosinophilia can infrequently accompany pleural fluid eosinophilia, which is a non-specific response seen with various disorders, including trauma and even repeated thoracenteses. Eosinophilic gastroenteritis (see Chapter 136) is often associated with blood eosinophilia. Of the various forms of vasculitis (see Chapter 292), only two are commonly associated with eosinophilia: hypersensitivity vasculitis and allergic granulomatous angiitis, or the Churg-Strauss syndrome, in which asthma, eosinophilia, and pulmonary and neurologic involvement are frequent. Although eosinophilia may uncommonly accompany rheumatoid arthritis (see Chapter 286), any associated eosinophilia is more commonly due to medications used to treat the disease. Cholesterol embolization (see Chapter 112) is at times associated with eosinophilia and hypocomplementemia, thus suggesting a secondary immunologic component. Two notable, apparently toxic diseases, the eosinophilia-myalgia syndrome caused by contaminated L-tryptophan (see Chapter 510) and the earlier toxic oil syndrome in Spain, were prominently associated with eosinophilia. Provides a comprehensive review of clinical conditions associated with eosinophilia. Reviews the manifestations, differential diagnosis, and management of idiopathic hypereosinophilic syndrome. Silverstein Blood cells are, in general, specified as being either lymphoid or myeloid (granulocytes, monocytes, erythrocytes, and platelets). Accordingly, hematologic malignancies are organized into lymphoproliferative or myeloproliferative disorders. Each of these disorders is operationally classified as being acute or chronic, depending on the proportion of immature precursor cells (blasts) in the bone marrow. In the myeloid lineage, the presence of more than 30% blasts in the bone marrow defines acute myeloid leukemia. A myeloid disorder that is not acute myeloid leukemia is referred to as either a myelodysplastic syndrome or a chronic myeloproliferative disease based, respectively, on the presence or absence of trilineage morphologic dysplasia, primarily involving the red blood cell series. Occasionally, a chronic myeloid disorder is not classifiable as either myelodysplastic syndrome or chronic myeloproliferative disease. As a group, the chronic myeloproliferative diseases are interrelated in that the clonal process originates at the myeloid progenitor cell level and may, secondarily, cause marrow fibrosis or undergo leukemic transformation. A similar consistent genetic abnormality has not been associated with the other chronic myeloproliferative diseases, and specific diagnosis is based on the presence or absence of certain clinical and laboratory characteristics. An increased red blood cell mass is required for the diagnosis of polycythemia vera. Because of referral bias, the epidemiologic information derived from these studies may not be generalizable to the population at large.
