Del rosso jq. The role of topical antifungal therapy for onychomycosis and the emergency of new agents. J clin aesthetic derm 2014;7(7):10–18. 84 invasive fungal infections russell e. Lewis and p. David rogers learning objectives upon completion of the chapter, the reader will be able to. 1. Differentiate epidemiologic differences and host risk factors for acquisition of primary and opportunistic invasive fungal pathogens. 2. Recommend appropriate empiric or targeted antifungal therapy for the treatment of invasive fungal infections. 3. Describe the components of a monitoring plan to assess effectiveness and adverse effects of pharmacotherapy for invasive fungal infections. 4. Evaluate the role of antifungal prophylaxis in the prevention of opportunistic fungal pathogens. Introduction i nvasive fungal infection or invasive mycoses are general terms for diseases caused by invasion of living tissue by fungi. In contrast to superficial mycoses (see chapter 83), invasive fungal infections are much less common, but are of greater medical concern because of their disproportionately higher severity and mortality. Approximately 1. 5 million people die each year from the 10 most common invasive fungal infections, which is higher than world health organization mortality estimates for tuberculosis (1. 4 million) or malaria (1. 2 million). 1 however, these numbers probably underestimate the actual mortality burden of invasive fungal disease considering that the four most common infections (cryptococcosis, invasive candidiasis, invasive aspergillosis, and pneumocystis jiroveci pneumonia) are often underdiagnosed and not reportable diseases to public health agencies (table 84–1). Invasive fungal infections are broadly categorized as either primary or opportunistic mycoses. Primary invasive fungal infections develop following exposure to fungal spores or conidia in the soil that, when disturbed, can become aerosolized and inhaled leading to infection, even in an immunocompetent patient exposed to a sufficient inoculum. Because these fungi are in specific soil types in select geographic areas, they are also referred to as endemic fungi. In the united states, three genera (histoplasma capsulatum, blastomyces dermatitidis, and coccidioides immitis/coccidioides posadasii) account for most of these infections (see table 84–1). In contrast, opportunistic fungal infections are most frequently encountered in setting of compromised host immune defenses, and are caused by a wider spectrum of less virulent fungal species that rarely cause infection in healthy patients (see table 84–1). Hence, the spectrum, severity, and outcome of opportunistic fungal infections are strongly influenced by the degree, type, and severity of host immunosuppression. As a general rule, opportunistic fungal infections are difficult to diagnose, but often fatal if not diagnosed early and treated aggressively. Occasionally, opportunistic fungal pathogens may be associated with outbreaks of invasive disease in otherwise nonimmunocompromised patients, especially if they are inadvertently inoculated into patients from contaminated drug solutions or medical devices. For example, in 2012 an outbreak of fungal meningitis and articular infections (n=751 cases) in 20 states was eventually traced by the centers for disease control and state health departments to contaminated preservative-free methylprednisolone solution used for epidural and articular injections in patients with chronic back or joint pain. The dematiaceous mold eventually linked to the fungal meningitis cases, exserohilum rostratum, had rarely been described as a human pathogen prior to the outbreak. 2 epidemiology and etiology endemic mycoses are capable of infecting otherwise healthy individuals. In immunocompromised patients, endemic fungal infections present with a more fulminant course (in the case of primary infections, or reactivate to cause life-threatening infection). Because initial symptoms of an endemic fungal infection are nonspecific and produce symptoms indistinguishable from other slowly progressing infections (eg, tuberculosis), a careful patient history concerning travel and activities that may have resulted in exposure to endemic fungi is essential for early diagnosis.

2. Placental and umbilical anatomical factors include malformations (e.G., chorioangioma, infarction, circumvallate placenta, placental mosaicism, obliterative vasculopathy of the placental bed, vascular malformations, or velamentous umbilical cord insertion), infarction or focal lesions, abruption, suboptimal implantation site (e.G., low-lying placenta), previa, insufficient uteroplacental perfusion, and single umbilical artery. 3. Fetal factors include constitutional (normal, "genetically small"), malformations (e.G., abnormalities of cns and skeletal system), chromosomal abnormality (under 5% ofsga infants. More likely in the presence of malformation), congenital infection (i.E., rubella and cytomegalovirus) (see chap. 48), and multiple gestation. C. Management of sga/iugr i. Pregnancy (see chap. 1).

E. Coli were discussed under eos (see 1.1.2.). P. Aeruginosa sepsis in lbw infants is high (76% in the nichd cohort). A number of bacterial factors, including lps, mucoid capsule, adhesins, invasins, and toxins (notably exotoxin a), contribute to its extreme virulence in premature infants as well as in debilitated adults and burn victims. Both lps and the mucoid capsule help the organism avoid opsonization and secreted proteases inactivate complement, cytokines, and immunoglobulin. The lipid a moiety oflps (endotoxin) causes the typical aspects of gram-negative septicemia (i.E., hypotension, dic). Exotoxin a is antigenically distinct from diphtheria toxin, but acts by the same mechanism. Adenovirus death protein (adp)-ribosylation of eukaryotic elongation factor 2 results in inhibition of protein synthesis and cell death. P. Aeruginosa is present in the intestinal tract of approximately 5% of healthy adults, but colonizes premature infants at much higher rates due to nosocomial acquisition of the bacteria.
