OBJECTIVE To determine the efficacy of azithromycin in the treatment of patients with typical cat-scratch disease. DESIGN Prospective, randomized, double blind, placebo-controlled clinical trial. SETTING Large military medical center and its referring clinics. PATIENTS Active duty military members and their dependents with laboratory-confirmed, clinically typical cat-scratch disease. INTERVENTION Study participants assigned by randomization to treatment with oral azithromycin or placebo for 5 days. OUTCOME MEASURES Lymph node volume was calculated using three dimensional ultrasonography at entry and at weekly intervals. The ultrasonographer was blinded to the treatment groups. Endpoint evaluations were predetermined as time in days to 80% resolution of the initial total lymph node volume. RESULTS Demographic and clinical data showed that the azithromycin and placebo treatment groups were comparable at entry although the placebo group tended to be older. Eighty percent decrease of initial lymph node volume was documented in 7 of 14 azithromycin-treated patients compared with 1 of 15 placebo-treated controls during the first 30 days of observation (P = 0.026). After 30 days there was no significant difference in rate or degree of resolution between the two groups. CONCLUSIONS Treatment of patients with typical cat-scratch disease with oral azithromycin for five days affords significant clinical benefit as measured by total decrease in lymph node volume within the first month of treatment.

OBJECTIVE. The goal was to determine whether home asthma telemonitoring with store-and-forward technology improved outcomes, compared with in-person, office-based visits. METHODS. A total of 120 patients, 6 to 17 years of age, with persistent asthma were assigned randomly to the office-based or virtual group. The 2 groups followed the same ambulatory clinical pathway for 12 months. Office-based group patients received traditional in-person education and case management. Virtual group patients received computers, Internet connections, and in-home, Internet-based case management and received education through the study Web site. Disease control outcome measures included quality of life, utilization of services, and symptom control. RESULTS. A total of 120 volunteers (45 female) were enrolled. The groups were clinically comparable (office-based: 22 female/38 male; mean age: 9.0 ± 3.0 years; virtual: 23 female/37 male; mean age: 10.2 ± 3.1 years). Virtual patients had higher metered-dose inhaler with valved holding chamber technique scores than did the office-based group at 52 weeks (94% vs 89%), had greater adherence to daily asthma symptom diary submission (35.4% vs 20.8%), had less participant time (636 vs 713 patient-months), and were older. Caregivers in both groups perceived an increase in quality of life and an increase in asthma knowledge scores from baseline. There were no other differences in therapeutic or disease control outcome measures. CONCLUSIONS. Virtual group patients achieved excellent asthma therapeutic and disease control outcomes. Compared with those who received standardized office-based care, they were more adherent to diary submission and had better inhaler scores at 52 weeks. Store-and-forward telemedicine technology and case management provide additional tools to assist in the management of children with persistent asthma.

Hospitalization of children with asthma declined at our institution between 1996 and 2000, before stabilizing for the past 5 years. The ages of children hospitalized since 2000 were examined to see if the demographics of the hospitalized population have changed to better understand why the hospitalization rate has remained the same despite continued, aggressive screening and education efforts. Data were gathered for our hospital through the Department of Defense Medical Health System Management Analysis and Reporting System (M2). The mean age (± SD) of children hospitalized in 2003 (2.84 ± 2.53) was less than the mean age for 2000 and 2002 (4.85 ± 3.7 and 4.61 ± 4.45), respectively (p < 0.05), and more infants less than 2 years of age were hospitalized in 2003 (33/60, 55% p < 0.01) and 2004 (32/68, 47% p < 0.05) than in 2000 (19/70, 27%). The diagnosis of asthma in hospitalized infants and young children has increased over the past 5 years, suggesting better recognition and providing a new target population for intervention with early asthma controller therapy.
