Itraconazole in the treatment of superficial cutaneous and mucosal Candida infections.

Superficial cutaneous and mucosal Candida infections are common and widely affect both the immunocompromised as well as the immunocompetent populations. Common infections may include Candida paronychia, cutaneous candidiasis, oral candidiasis, vulvovaginal candidiasis, and Candida onychomycosis. Although C albicans has been considered to be the most common pathogen, other Candida species have emerged as potential causes of certain infections. Currently, a variety of antifungal agents is available to treat these infections. They include fluconazole, ketoconazole, and itraconazole. These agents have been widely used to treat fungal infections, including superficial and systemic candidiasis. However, some concerns exist regarding safety associated with long-term use of ketoconazole, and emerging issues of Candida resistance to fluconazole in some patient subsets have been reported. Itraconazole has proven efficacy in treating cutaneous and mucosal Candida infections. Additionally, studies have demonstrated that itraconazole may have increased efficacy and an excellent safety profile when administered in a pulse-dose, or intermittent fashion, for superficial mycotic infections. Itraconazole is an effective agent that warrants consideration when selecting treatment for Candida infections.

When the pregnant woman experiences itching.

It is important for dermatology nurses to know the presentation and outcome of the various dermatoses which are unique to pregnancy so that they may identify potential risks to the mother and fetus and evaluate future pregnancies. Differentiating features, adjunctive laboratory studies, and the medical implications regarding the risk of recurrence in a future pregnancy are examined in this article.

Prognostic value of assessing contact system activation and factor V in systemic inflammatory response syndrome.

OBJECTIVE: To test if serially sampled determinations of the contact system proteins and factor V have prognostic value for death in patients who develop the systemic inflammatory response syndrome. DESIGN: Prospective, observational study with sequential measurements in an inception cohort. SETTING: Medical intensive care unit (ICU) in a community hospital. PATIENTS: Over a 1-yr period, a population base sample of 23 patients was selected from all ICU admissions who met established criteria for the systemic inflammatory response syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Components of the contact system, factor XII, prekallikrein, high-molecular-weight kininogen, factor XI, alpha 2-macroglobulin-kallikrein complexes and factor V values were measured in plasma samples collected serially (day of admission, and at 2, 12, 24, 48 and/or 72 hrs or at discharge). Data were analyzed to determine if admission values or serially obtained values within 48 hrs were useful in predicting outcome. Fourteen patients survived and nine died. At admission, in all patients, assay values indicated that prekallikrein, high-molecular-weight kininogen, and factor V were significantly lower than normal (as observed in a range of 20 to 23 healthy adults), alpha 2-macroglobulin-kallikrein complexes were higher than normal, while concentrations of factor XII and factor XI were in the normal range. No differences were detected in the admission values between survivors and nonsurvivors, nor between patients with positive or negative blood cultures. However, subsequent values demonstrated a difference in values between survivors and nonsurvivors. Survivors showed improvement in high molecular weight kininogen values and higher than normal factor V values, as compared with nonsurvivors. CONCLUSIONS: Low or persistently low serial factor XII, high-molecular-weight kininogen and factor V values are associated with a poor prognosis, whereas high or increasing values of factor XII, high-molecular-weight kininogen, prekallikrein, and factor V all correlate with a favorable outcome.
