Treatment of invasive squamous cell carcinoma with 5-percent imiquimod cream.

Skin cancer is a major problem in the elderly. Squamous cell carcinoma (SCC), the second most common skin cancer, typically occurs in this age group. Despite a number of modalities readily available for treatment (depending on the tumor site, and depth of invasion) there remains the problem of individuals with multiple lesions who may be unsuitable for existing treatments for SCC, particularly surgery. Consequently, the search for novel treatments continues. To our knowledge, there are only 6 published reports of invasive SCC treated with 5-percent imiquimod cream.

Pyodermatitis-pyostomatitis vegetans complicated by methicillin-resistant Staphylococcus aureus infection.

Pyodermatitis-pyostomatitis vegetans (PPV), a rare disorder of the skin and oral mucosa, is considered a highly specific marker for inflammatory bowel disease, especially ulcerative colitis (UC). Oral lesions (pyostomatitis vegetans) are seen without skin involvement but rarely without gastrointestinal symptoms. Bowel symptoms may be minimal and precede the onset of other lesions by months or years. Dermatologically, PPV is characterized by annular, pustular lesions, which may precede or appear at the same time as the oral lesions. We report a case of PPV and UC in which presentation was confused by acneiform lesions and methicillin-resistant Staphylococcus aureus colonization. Management was complicated because of the patient's job commitments and need to travel, and the involvement of a number of different specialties at different locations.

Comparative studies of female sex pheromone components and male response of the corn stalk borer Sesamia nonagrioides in three different populations.

Studies to determine possible differences in the pheromone communication system of three different populations of the corn stalk borer Sesamia nonagrioides (Lef.) in France. Spain. and Greece were carried out. The two main pheromone components (Z)-11-hexadecenyl acetate (Z11-16:Ac) and (Z)-11-hexadecenol (Z11-16:OH), were detected in all analyses with very small differences in the three populations. Among the minor components, analyzed by GC-MS on concentrated gland extracts from French and Greek origin females, (Z)-l1-hexadecenal (Z11-16:Ald) was detected in minor amounts. Wind-tunnel and field studies revealed similar a male response in the three populations to pheromone glands extracts and synthetic pheromone regardless of the female/male origin. The results do not support the assumption of the existence of different pheromone types of the corn stalk borer S. nonagrioides due to geographic isolation.
