The Diagnosis of Photosensitivity
Archives of Dermatology, 2000Many photosensitive patients are seen for consultation when they have no lesions, so a detailed history is important. The differential diagnosis is based on the age at which the symptoms first occurred. The striking symptoms and signs are discussed, and advice is given on which additional investigations are necessary and when phototesting must be ...

UV irradiation (365 nm) of air-saturated methanol solutions of 20 drugs absorbing in the 300--400 nm region gave rise to oxygen uptake, as determined with a polarographic oxygen electrode. The drugs were tested for photosensitizing capability by either a Type I (free radical) or a Type II (single molecular oxygen) mechanism.

Study on the photosensitivity of photosensitive fibers
SPIE Proceedings, 2005The photosensitivity of photosensitive fibers is studied experimentally and theoretically. In the experiment, the relationship between the diffractive index increment of photosensitive fibers and UV irradiating dose based on an unbalanced Mach-Zehnder Interferometer (MZI) is measured.

Employing photodestructible surfactants in gelatin-based aqueous gels presents novel possibilities for controlling colloidal and aggregation properties of surfactant gelatin complexes. Light-triggered breakdown of the gelatin-bound photosurfactant aggregates causes dramatic changes in viscosity and aggregation.

When photosensitivity presents in children, it frequently signifies a serious or potentially serious condition. Both disorders with genetic bases and idiopathic disorders are discussed.

Summary: Not all visually sensitive patients need antiepileptic drug treatment, and even those who do can benefit from additional preventive measures. Visually provoked seizures, in particular, can be prevented or treated by avoiding or altering the triggering stimulus.

This is a report of the occurrence of seizures or their equivalents induced by photic stimuli in a family of 5, one of whom, a 14-year-old girl, was the first to suggest the proper etiological common denominator for her own convulsive manifestations and for the less overt incidents in other members of the family.

During a study of photodynamic action in white mice we became aware of the effect of heat on this process. A review of the literature revealed that little work had been done regarding this problem, and available reports provided conflicting results. In an effort to resolve these differences, we decided to study the influence of heat on the photodynamic

Flutamide is a non‐steroid antiandrogen used in advanced prostate cancer. This drug induces liver toxicity. Other side effects have been reported, especially four cases of photosensitivity. Our patient presented a sun‐exposed eruption that disappeared when flutamide was discontinued and relapsed when it was rechallenged. Photopatch tests were negative.

Photosensitivity in the elderly
British Journal of Dermatology, 1990Photosensitivity to drugs and chemicals in the elderly is more prevalent due to more frequent use of medications. Phototoxic reactions to common, orally administered drugs such as diuretics, cardiac agents and antidiabetics may occur and the reactions may be remedied by discontinuing drug therapy.
