We present a facile synthesis of manganese oxide (MnO(2)) nanocomposite with ultraviolet (UV) photosensitive characteristic by a solid-state reaction based on the reduction of potassium permanganate (KMnO(4)) by aniline, which provides a new family and more selectivity for UV photosensitive nanomaterials in the future.

Photosensitive disorders in children are not uncommon in our country. It is often difficult to establish the diagnosis, either due to confusing presentation or ignorance by the parents. We review the presentation and management of photosensitive disorders in children.Detailed history and thorough clinical examination is essential in arriving at a particular diagnosis. Photosensitive disorders i...

PURPOSE Photosensitivity is a well-described phenomenon; affecting a relatively small proportion of individuals with epilepsy. Typically people with photosensitive epilepsies are at risk of seizures induced by shimmering natural light, strobe lights and with particular patterns or flicker frequencies on television and video games. METHODS & RESULTS We present a novel case of photosensitivity ...

Photosensitive disorders are common, affecting up to 5% of HIV-positive patients. HIV itself induces photosensitivity but photoaggravated drug reactions, porphyria cutanea tarda and nutritional disorders such as pellagra are also more common in patients with HIV. In South Africa, actinic lichenoid leukomelanoderma of HIV is a unique photosensitive disorder which is associated with advanced HIV....

Photosensitivity reactions are recognized as unwanted adverse effects of an array of commonly administered topical or systemic medications, including nonsteroidal antiinflammatory agents, antifungals, and antimicrobials. When a drug induces photosensitivity, exogenous molecules in the skin absorb normally harmless doses of visible and UV light, leading to an acute inflammatory response. In phot...

PURPOSE Human photosensitive epilepsy models have been used as proof of principle (POP) trials for epilepsy. Photosensitive patients are exposed to intermittent photic stimulation and the reduction in sensitivity to the number of standard visual stimulation frequencies is used as an endpoint. The aim of this research was to quantify the predictive capabilities of photosensitive POP trials, thro...
