Many experts now consider voriconazole as the initial drug of choice for invasive aspergillosis in patients without significant contraindications (e.g., drug interactions or preexisting liver dysfunction) to azole therapy. 

Some forms of invasive candidiasis are dominated by deep organ infection and may never be detected by blood cultures. Chronic disseminated candidiasis or hepatosplenic candidiasis is a unique form of candidemia seen after recovery from neutropenia. Candidemia during the period of neutropenia may be initially localized to the portal circulation with dissemination to contiguous organs. After recovery of neutrophils, an inflammatory response is seen against areas of focal infection in the liver and spleen. This inflammatory response produces abdominal pain that is associated with... 

The 23-valent pneumococcal polysaccharide vaccine is recommended for use in all adults 65 years of age or older and adults less than 65 years who have medical comorbidities that increase the risk for serious complications from S. pneumoniae infection, such as chronic pulmonary disorders, cardiovascular disease, diabetes mellitus, chronic liver disease, chronic renal failure, functional or anatomic asplenia, and immunosuppressive disorders. Alaskan natives and certain Native American populations are also at increased risk. Children over the age of 2 years may be vaccinated with the 23-valent pneumococcal polysaccharide vaccine if they are at increased risk for invasive S. pneumoniae infections, such as children with sickle cell anemia or those receiving cochlear implants. 

Disulfoton induced the liver MFO system in animals (Stevens et al. 1973). In the same study, exposure to disulfoton orally for 3 days also increased ethylmorphine N-demethylase and NADPH oxidase activities, but had no effect on NADPH cytochrome c reductase. Thus, the induction of the MFO system required repeated dosing with relatively high doses. Furthermore, these changes are not specific for disulfoton exposure, and these subtle liver effects require invasive techniques in humans to obtain liver tissue for performance of these enzyme assays. 

Proton NMR spectroscopy ( H MRS) has shown to offer excellent possibilities for evaluation of biochemistry in vivo. Due to its non-invasive character it is of increasing interest not only for the study of human brain diseases, which describe the majority of clinical applications, but also for metabolic characterization of organs outside the brain, as prostate, liver, heart or skeletal muscle. Studies on skeletal muscle have been of increasing interest during the last years, since it was shown that MRS enables the differentiation between two muscular lipid compartments the bulk fat components along the fasciae and muscular boundaries, which are called extramyocellular lipids (EMCL), and the metabolically highly active intramyocellular lipids (IMCL). The latter are stored in spherical droplets in the cytoplasm of muscle... 

The response of the body to an invasion by a pathogen involves not only the immnne system bnt other tissnes in which changes in metabolism are essential for a satisfactory response. These inclnde adipose tissne, mnscle and liver, all of which provide precnrsor molecnles (i.e. bnilding materials) for the synthesis of the macromolecnles required for proliferation (Table 17.5). In addition, they provide fuels, the oxidation of which generates ATP for the immune cells, particnlarly to snpport proliferation of the cells in the lymph nodes bnt also for the precnrsor cells in the bone marrow where proliferation increases to prodnce new immune and other cells (Table 17.6).

Chronic 2-year studies showed a significant increase in the incidences of adenomas and carcinomas of the nasal cavity in high-dose rats fed diets containing 3000ppm of 2,6-xylidine. The carcinomas were highly invasive and frequently destroyed the nasal turbinates and nasal septum. Rhabdomyosarcomas, a rare tumor of the nasal cavity were also observed in the high-dose male and females. The nonneo-plastic lesions observed in the nasal cavity included acute inflammation, epithelial hyperplasia, and squamous metaplasia. In addition, subcutaneous fibromas and fibrosarcomas occurred in both males and females and there was an increased incidence of neoplastic nodules in the livers of female rats. 

Plasma protein binding is 99.8%. It is extensively distributed into tissues that are prone to fungal invasion. Concentrations in the lung, kidney, liver, bone, stomach, spleen, and muscle were found to be 2 to 3 times higher than the corresponding plasma concentration. Following IV administration, the volume of distribution averaged 796 185 L. 

Liver transplant patients In liver transplant patients, there was a significantly higher incidence of tissue-invasive CMV disease in the valganciclovir-treated group compared with the oral ganciclovir group. Valganciclovir is not indicated for use in liver transplant patients. 

Recently, there has been success in generating cocultures that more faithfully reproduce in vivo metastatic microenvironments. An ex vivo microscale liver perfusion bioreactor was used to assess metastatic seeding, mimicking the salient features of fluid dynamics and functionality of hepatic parenchyma. Invasion and subsequent growth of breast and prostate carcinoma cells were detected by two-photon microscopy of fluorescently labeled cells. Tumors...
