Fast reliable photography for the dermatologist.

Color photography using a 35 mm single lens reflex camera is a useful tool for both academic and practicing dermatologists. With an electronic flash and a macro lens, the production of high quality photographs requires only a few seconds. Equipment and techniques effective in office photography are surveyed and evaluated.

Treatment of lip keratoses (actinic cheilitis) with topical fluorouracil.

Topical (5-fluorouracil [5-FU]) as a 5% solution was used to treat isolated actinic keratoses of the lips as well as diffuse actinic damage of the lower lip. Although producing considerable temporary discomform final results proved excellent, with recurrences in only two of 12 patients treated. Preliminary biopsy of suspicious infiltrated areas is mandatory, as is careful follow-up to ensure complete healing. Topical fluorouracil is an alternative to surgical excision of the vermillion border of the lip in those patients with severe diffuse actinic damage of the lips.

Genotypic Responses to Salinity: Differences between Salt-sensitive and Salt-tolerant Genotypes of the Tomato.

Four ecotypes of the species Lycopersicon cheesmanii ssp. minor (Hook.) C.H. Mull. from the Galapagos Islands were compared with L. esculentum Mill cv. VF 36 with respect to salt tolerance. The L. cheesmanii ecotype that proved most salt-tolerant was selected for detailed comparison with the L. esculentum cultivar. Plants were grown in modified Hoagland solution salinized with synthetic seawater salt mix. Growth rates under saline conditions were examined and amino acid, sugar, total amino nitrogen, free acidity, and Na and K levels in the tissues of the most and least tolerant plants were measured under salt stress and nonstress conditions. Results indicate that all Galapagos ecotypes were far more salt-tolerant than was the esculentum cultivar. They could survive in full strength seawater nutrient solution while the esculentum cultivar could not in most cases withstand levels higher than 50% seawater. Growth rates were reduced in both species under saline conditions but the esculentum cultivar was more severely affected. High levels of total amino nitrogen, specific amino acids, and free acidity along with low sodium content were found in the salt stressed VF 36 cultivar. The opposite responses were noted in the salt stressed treatments of the Galapagos ecotype. Tissue sugar levels did not appear to be similarly correlated with salt stress in either species. Potassium content fell sharply during salinization in the Galapagos ecotype while in the esculentum cultivar it declined relatively little even at high levels of salinity.

Treatment of zoster and postzoster neuralgia by the intralesional injection of triamcinolone: a computer analysis of 199 cases.

On the basis of this study of 111 patients with herpes zoster and 88 with postherpetic neuralgia, it is suggested that the intradermal injection of triamcinolone in saline is a valuable treatment. Mild complications were pain, hemorrhage, abscesses, atrophy, moon face and possibly thrombophlebitis. Zoster patients required treatment for about half as long as those in previously reported control series. In patients treated for active herpes zoster, postzoster neuralgia occurred with about one-third of the frequency noted in other series. In postzoster neuralgia, the patient was benefited sufficiently in 62.5% of the cases to find that life was worth living again.
