Systemic corticosteroids for allergic fungal rhinosinusitis and chronic rhinosinusitis with nasal polyposis: a comparative study.

OBJECTIVES: To compare the effect of preoperative high-dose systemic corticosteroids on the radiographic and endoscopic appearance of allergic fungal rhinosinusitis (AFRS) and chronic rhinosinusitis with nasal polyposis (CRSwNP). STUDY DESIGN AND SETTING: Eight AFRS and 10 CRSwNP patients underwent computed tomographic (CT) scans and then received preoperative 1 mg/kg prednisone for 10 days. CT scans were repeated 1 day before surgery and compared with pretreatment scans (Lund-MacKay radiologic scoring system). The endoscopic appearance was recorded intraoperatively. RESULTS: The score dropped from 16 (66.4%) to 4.75 in the AFRS group and from 18.4 (23%) to 14.1 in the CRSwNP group (P=0.0064). Intraoperatively, most sinus mucosal surfaces appeared normal in the AFRS patients but were markedly edematous in the CRSwNP patients. CONCLUSION: Radiographic response of AFRS to systemic corticosteroids is significantly greater compared with CRSwNP. This finding is supported by endoscopic observation.

The rising incidence of adult acute epiglottitis and epiglottic abscess.

OBJECTIVE: To examine preliminary observations that the incidence of adult acute epiglottitis has risen between 1986 and 2000. MATERIALS AND METHODS: Demographics, annual and seasonal occurrences, clinical presentation, diagnostic procedures, treatment, airway management, and complications of 116 consecutive adult patients with laryngoscopically confirmed acute epiglottitis are presented. RESULTS: The mean annual incidence of acute epiglottitis per 100,000 adults significantly increased from 0.88 (from 1986-1990) to 2.1 (from 1991-1995) and to 3.1 (from 1996-2000) (P <.001). This rise seems to be unrelated to Haemophilus influenzae type b infection but related to miscellaneous pathogenic bacteria. During these periods, the number of epiglottic abscesses increased concomitantly with the rise in the incidence of acute epiglottitis (from 4/14 episodes [29%], to 8/38 [21%], and to 16/66 [24%], respectively), showing a relatively constant ratio between both phenomena (P =.843). Twenty-five patients (21%) underwent airway intervention, 16 because of objective respiratory distress and 9 because of imminent respiratory obstruction. Stepwise logistic regression showed that drooling, diabetes mellitus, rapid onset of symptoms, and abscess formation were associated with airway obstruction. Diverse origins for the epiglottic abscess, either from coalescent epiglottic infection or from mucopyocele of the tongue base, are suggested. CONCLUSIONS: A rise in the incidence of acute epiglottitis and a concomitant rise in the number of epiglottic abscesses were established. Although the course of acute epiglottitis is often benign and can be safely treated with a conservative management approach, delayed airway obstruction may develop from a few hours to days after admission.

The erythrocyte adhesiveness/aggregation test (EAAT). A new biomarker to reveal the presence of low grade subclinical smoldering inflammation in individuals with atherosclerotic risk factors.

BACKGROUND: Multiple acute phase proteins and atherosclerotic risk factors increase the aggregability of erythrocytes. METHODS AND RESULTS: We used a simple slide test and image analysis to determine the degree of erythrocyte adhesiveness/aggregation in the peripheral blood of 222 women and 221 men with no, one, two or more atherosclerotic risk factors. The degree of erythrocyte adhesiveness/aggregation correlated significantly with the concentration of commonly used variables of the acute phase response. We also showed that individuals with low erythrocyte adhesiveness/aggregation tend to be younger and to have fewer risk factors for atherosclerosis, including diabetes mellitus, hypertension, hyperlipidemia and smoking. CONCLUSIONS: The association between increased erythrocyte adhesiveness/aggregation, higher concentrations of acute phase proteins, and increased atherosclerotic risk factors points to a possible clinical applicability of the erythrocyte adhesiveness/aggregation test (EAAT) to reveal the presence of both low-grade subclinical smoldering inflammation and morbid biology in individuals with risk factors for atherosclerosis.
