Safety and immunogenicity of a proteosome-Shigella flexneri 2a lipopolysaccharide vaccine administered intranasally to healthy adults.

We studied the safety and immunogenicity of a Shigella flexneri 2a vaccine comprising native S. flexneri 2a lipopolysaccharide (LPS) complexed to meningococcal outer membrane proteins-proteosomes-in normal, healthy adults. A two-dose series of immunizations was given by intranasal spray, and doses of 0.1, 0.4, 1.0, and 1.5 mg (based on protein) were studied in a dose-escalating design. The vaccine was generally well tolerated. The most common reactions included rhinorrhea and nasal stuffiness, which were clearly dose related (P < or = 0.05). These reactions were self-limited and generally mild. The vaccine elicited S. flexneri 2a LPS-specific immunoglobulin A (IgA), IgG, and IgM antibody-secreting cells (ASCs) in a dose-responsive manner. At doses of 1.0 or 1.5 mg, highly significant (P < 0.001) increases in ASCs of all antibody isotypes occurred and 95% of subjects had an ASC response in at least one antibody isotype. Dose-related serum antibody responses were observed, with geometric mean two- to fivefold rises in specific serum IgA and IgG titers and two- to threefold rises in IgM in the 1.0- and 1.5-mg-dose groups (P < 0.0001 for each isotype). Elevated serum antibody levels persisted through day 70. Increases in fecal IgG and IgA and also in urinary IgA specific for S. flexneri 2a LPS were demonstrated. These were most consistent and approached statistical significance (P = 0.02 to 0.12 for various measures) on day 70 after the first dose. The magnitude of immune responses to intranasally administered proteosome-S. flexneri 2a LPS vaccine is similar to those reported for live vaccine candidates associated with protective efficacy in human challenge models, and further evaluation of this product is warranted.

The effect of sunscreen on the efficacy of insect repellent: a clinical trial.

Sunscreen loses efficacy when used with the insect repellent N,N -diethyl-3-methylbenzamide (diethyltoluamide; deet). A previous study demonstrated a 33.3% decrease in sun protection factor when insect repellent and sunscreen were applied sequentially to the skin. The purpose of this study was to determine whether the efficacy of insect repellent is affected by two different formulations of sunscreen. The combination of sunscreen and insect repellent was tested in 8 groups: a control group (no sunscreen or insect repellent), sunscreen alone (two groups [gel and cream]), insect repellent alone, insect repellent applied before sunscreen (two groups), and insect repellent applied after sunscreen (two groups). The results of this study showed that insect repellent has the same efficacy even when sunscreen is applied with it. This indicates that in the formulations tested, sunscreen does not reduce the efficacy of insect repellent.

Confluent and reticulated papillomatosis: response to minocycline.

BACKGROUND: Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud is an uncommon disorder of unknown cause for which a variety of treatments have been proposed. OBJECTIVE: We attempted to evaluate the effectiveness of oral minocycline. METHODS: Nine patients with CRP were treated with oral minocycline, 50 mg twice a day, for 6 weeks. The average follow-up period was 11 months. Recurrence rate, side effects, and effectiveness of therapy were assessed. RESULTS: All patients except two had a 90% to 100% response to therapy. Recurrences were noted in three patients, all of whom responded to re-treatment with minocycline. None of the nine patients had an adverse reaction. CONCLUSION: Minocycline, 50 mg twice a day, is safe and effective for CRP.

Superficial papillary adenomatosis of the nipple: a case report and review of the literature.

Superficial papillary adenomatosis of the nipple is a benign tumor of the ductal epithelium that clinically resembles Paget's disease. Histologically, the tumor is characterized by proliferating ductal structures lined by a double layer of columnar epithelium. Keratin cysts and apical intraluminal projections are commonly found. Since this entity's original description as "florid papillomatosis" in 1954, 174 cases have been reported in the English language literature. We review these cases and report a classic example.

Staphylococcus aureus as a cause of perianal dermatitis.

Perianal dermatitis has been reported to be caused by group A beta-hemolytic Streptococcus. We present a case caused by Staphylococcus aureus. A clinical clue pointing to this organism was the presence of satellite pustules. Identifying the pathogen in perianal dermatitis is therapeutically important, as oral penicillin VK will not be effective if S. aureus is the true cause. Other streptococcal and staphylococcal cutaneous infections may exhibit overlapping clinical features, including scarlet fever, impetigo, toxic shock syndrome, and cellulitis.
