Over the next hour, he regains consciousness, but still shows signs of significant confusion, and cannot supply his name, or identify the day of the week or the current President cardiovascular disease 2010 purchase procardia from india. A counselor comes to see him to discuss the likely adverse outcomes of continued alcohol ingestion, and he is referred to a shelter and a treatment program. Chronic ingestion of excessive quantities of alcohol can have insidious effects on hepatic function, as fibrotic hard- ening of the liver alters several aspects of structure and function. Indeed, alcohol abuse is one of the most important causes of chronic liver disease, and cirrhosis (irreversible deposition of excess collagen in the liver) accounts for the majority of all medical deaths among alcoholics. Products of ethanol metabolism, most notably acetaldehyde, impair several aspects of hepatocyte metabolic function, as well as producing oxidative stress and forming protein adducts that may trigger adverse immune reactions that lead to cell death. In its initial stages, alcoholic liver disease involves the accumulation of fat in the liver. Ultimately, hepatic stellate cells are activated to produce collagen, and this occurs chronically if ingestion of excessive amounts of alcohol continues. In a subset of patients, hepatitis and fibrosis will progress to cirrhosis, characterized by fibrous bands connecting the portal triads with central veins, and small, regenerative nodules. Patients with alcoholic liver disease that has progressed at least to hepatitis and fibrosis present with a spectrum of symptoms of chronic liver failure, including jaundice, nausea, and malaise. Male patients may have hypogonadism and feminization, ascribable to both the direct toxic effects of ethanol on testicular Leydig cells and effects on estrogen production and reduced estrogen breakdown. In severe cases, there can be a collection of fluid in the abdominal cavity known as ascites that may become infected (see Chapter 55), hepatic encephalopathy, renal failure, and eventually death. The primary treatment is to secure abstinence from alcohol, although some liver changes may be irreversible even after drinking has stopped. When ammonia degradation is reduced, it can accumulate in the plasma to levels that become toxic to the central nervous system. Patients will experience a gradual decline in mental status with confusion and dementia, followed eventually by coma if the condition is untreated. First, if hepatocyte function is compromised, there is less capacity to degrade ammonia coming from the intestine and extraintestinal sites. Second, if blood flow through the liver is impaired by cirrhosis and portal hypertension has set in (see also Chapter 55), collateral blood vessels may form that shunt the portal blood flow around the liver, bypassing the residual capacity of the liver to degrade ammonia. It is likely that both mechanisms contribute to the rise in plasma ammonia in the setting of long-standing liver disease. A 2-year-old boy is brought to the pediatrician because his mother has noted a persistent, dark brown coloration of his urine. He is otherwise healthy, and his mother notes that a cousin displayed similar symptoms. Bile produced by this child would be expected to display which of the following changes in composition compared with that of a normal child Bilirubin A) B) C) D) E) F) Decreased Increased Decreased Increased Decreased Increased Urobilinogen Decreased Increased Increased Decreased Decreased Increased Bile Acids Decreased Increased Decreased Increased Unchanged Unchanged 581 the colon to form short-chain fatty acids. In turn, the pH of the colonic lumen is decreased, and more of the ammonia being formed in that site is protonated and "trapped" as ammonium ion to be lost to the stool. Similarly, patients can be given a nonabsorbable antibiotic such as neomycin that reduces the level of bacterial colonization in the intestine, thereby reducing ammonia production. Finally, patients with liver disease are often advised to follow a lowprotein diet, again in an effort to reduce ammonia production in the intestine. Ultimately, however, the only lasting treatment for hepatic encephalopathy is a liver transplant, and mental symptoms often are reversible if they have not been too long-standing. Conjugation increases the solubility of bilirubin and prevents its reuptake from the intestinal lumen. Only conjugated bilirubin is transported into the bile, but both conjugated and unconjugated bilirubin may regurgitate from the hepatocyte into the plasma.

Aspergillomas ("fungal balls") grow in preexisting pulmonary cavities or bronchogenic cysts without invading pulmonary tissue; almost all patients have underlying lung disease, such as cystic fibrosis or tuberculosis cardiovascular disease defined discount procardia 30mg without a prescription. Patients with otomycosis have chronic otitis media with colonization of the external auditory canal by a fungal mat that produces a dark discharge cardiovascular system stress purchase procardia in india. This form of aspergillosis occurs most commonly in immunocompetent children with asthma or cystic fibrosis and can be a trigger for asthmatic flares heart disease cardiomyopathy generic 30 mg procardia with amex. Allergic sinusitis occurs in children with nasal polyps or previous episodes of sinusitis or who have undergone sinus surgery. Allergic sinusitis is characterized by symptoms of chronic sinusitis with dark plugs of nasal discharge. Etiology Aspergillus species are ubiquitous molds that grow on decaying vegetation and in soil. Epidemiology the principal route of transmission is inhalation of conidia (spores) originating from multiple environmental sources (eg, plants, vegetables, dust from construction or demolition), soil, and water supplies (eg, showerheads). Incidence of disease in hematopoietic stem cell transplant recipients is highest during periods of neutropenia or treatment for graftversus-host disease. In solid organ transplant recipients, the risk is highest 1 to 6 months after transplantation or during periods of increased immunosuppression. Cutaneous aspergillosis occurs less frequently and usually involves sites of skin injury, such as intravenous catheter sites, sites of traumatic inoculation, and sites associated with occlusive dressings, burns, or surgery. Isolation of Aspergillus species or molecular testing with specific reagents is required for definitive diagnosis. The organism is usually not recoverable from blood (except A terreus) but is isolated readily from lung, sinus, and skin biopsy specimens when cultured on fungal media. Asper gillus species can be a laboratory contaminant, but when evaluating results from ill, immunocompromised patients, recovery of this organism frequently indicates infection. Biopsy of a lesion is usually required to confirm the diagnosis, and care should be taken to distinguish aspergillosis from mucormycosis, which appears similar by diagnostic imaging studies. An enzyme immunosorbent assay serologic test for detection of galactomannan, a molecule found in the cell wall of Aspergillus species, from the serum or bronchoalveolar lavage fluid is available commercially and has been found to be useful in children and adults. Monitoring of serum antigen concentrations twice weekly in periods of highest risk (eg, neutropenia, active graft-versus-host disease) may be useful for early detection of invasive aspergillosis in at-risk patients. False-positive test results have been reported and can be related to consumption of food products containing galactomannan (eg, rice, pasta) or cross-reactivity with antimicrobial agents derived from fungi (eg, penicillins, especially piperacillin-tazobactam). A negative galactomannan test result consistently occurs in patients with chronic granulomatous disease. Children frequently do not manifest cavitation or the air crescent or halo signs on chest radiography, and lack of these characteristic signs does not exclude the diagnosis of invasive aspergillosis. In allergic aspergillosis, diagnosis is suggested by a typical clinical syndrome with elevated total concentrations of immunoglobulin (Ig) E (1,000 ng/mL) and Aspergillus-specific serum IgE, eosinophilia, and a positive result from a skin test for Aspergillus antigens. In people with cystic fibrosis, diagnosis is more difficult because wheezing, eosinophilia, and a positive skin test result not associated with allergic bronchopulmonary aspergillosis are often present. Voriconazole has been shown to be superior to amphotericin B in a large, randomized trial in adults. Therapy is continued for at least 12 weeks, but treatment duration should be individualized. Monitoring of serum galactomannan concentrations in those with significant elevation at onset may be useful to assess response to therapy concomitant with clinical and radiologic evaluation. Voriconazole is metabolized in a linear fashion in children, so the recommended adult dosing is too low for children. Children 12 years and older who weigh 50 kg or more should receive the adult dose. Close monitoring of voriconazole serum trough concentrations when oral voriconazole is used is critical for efficacy and safety and because there is high interpatient variability in metabolism.
