Pediatric Wells syndrome (eosinophilic cellulitis) after vaccination: A case report and review of the literature.

A 4-year-old boy presented with erythematous vesicular plaques, ulceration, edema, and pruritus on the left foot and ankle 10 days after receiving the tetanus, diphtheria, pertussis, and polio; measles, mumps, rubella, and varicella; and hepatitis A/B vaccines. Biopsy showed eosinophilic infiltrates and flame figures, suggesting Wells syndrome. Patch testing showed a 1+ reaction to neomycin and aluminum hydroxide, with a recall reaction of Wells syndrome of the feet bilaterally. We report a rare case of pediatric Wells syndrome triggered by nonthimerosal vaccine components confirmed by patch testing.

Home-based subcutaneous immunoglobulin therapy vs hospital-based intravenous immunoglobulin therapy: A prospective economic analysis.

BACKGROUND: Home-based subcutaneous immunoglobulin (SCIg) administration used for immunoglobulin replacement therapy for patients with primary immunodeficiency has been demonstrated to have benefits compared with hospital-based intravenous immunoglobulin (IVIg) therapy. OBJECTIVE: To estimate the cost savings associated with treating eligible patients with primary immunodeficiency with home-based SCIg compared with hospital-based IVIg in a prospective study. METHODS: This study was a 12-month prospective observational study that collected information from patient charts, directly from the nurse for time spent with patients and materials used, and directly from the physicians for billing. Data were collected on case report forms at each follow-up. Data were entered in a web-based REDCap database and statistical comparisons were performed. RESULTS: The average hospital (including hospital personnel such as nurses) and physician costs were significantly lower in the SCIg group ($1,836 and $84, respectively) than in the IVIg group ($4,187 and $744, respectively), which supported the findings in the number of hospital and physician visits in each group. The total cost was reported from the hospital's (only hospital-related costs) and the health system's (hospital- and physician-related costs) perspectives. For the 2 perspectives, the SCIg group reported significantly lower average total costs than the IVIg group. CONCLUSION: This is the first prospective analysis of the cost savings associated with home-based SCIG therapy compared with hospital-based IVIG therapy. These findings could help justify provision of home-based therapy training to suitable patients to lower health care costs or improve the capacity of care.

Newer approaches in topical combination therapy for acne.

Acne vulgaris is a common chronic inflammatory cutaneous disease involving the pilosebaceous unit. Its pathophysiology is multifactorial and complex, including obstruction of the pilosebaceous unit due to increased sebum production, abnormal keratinization, proliferation of Propionibacterium acnes (P. acnes), and inflammation. Topical agents are the most commonly used therapy for acne. First generation topicals mainly consist of single agent retinoids, benzoyl peroxide (BPO) and antibacterials that target comedones, P. acnes, and inflammation. Novel topical therapies include combination products with advanced vehicle formulations that target multiple acne pathophysiologies and offer simplified treatment regimes. For example, the combination of clindamycin and tretinoin in a unique vehicle formulation allows for progressive follicle penetration and decreased irritation, resulting in increased efficacy. Furthermore, adapalene or clindamycin with BPO combinations target comedones, inflammation, and P. acnes synergistically. These newer combination products have the potential to increase both efficacy and patient adherence when compared with single agent treatment.
