ARSENIC KERATOSIS- PRECANCEROUS CONDITION

Oral submucous fibrosis as a precancerous condition.

An evaluation of the malignant potential of submucous fibrosis, based on observations of 89 patients with the disease in Ernakulam District, Kerala, India was done. Out of the 89 patients, 12 were referred patients and 77 were diagnosed in population based studies. At the time of first examination oral cancer was found to be coexistent in nine (10%) cases. For 66 patients follow-up observations...

Arsenic-related Bowen's disease, palmar keratosis, and skin cancer.

Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, Bowen's disease, basal-cell-carcinoma,...

Actinic keratosis: new concepts and therapeutic approaches for an ancestral condition.

As I write this contribution to Spain’s most prestigious dermatology journal, it is clear I need not provide a description of actinic keratosis (AK), but I do feel that experience will allow me to reflect instructively and readably on the subject of how therapy has evolved over the years. Ours is a Mediterranean country with a high incidence of AK. We enjoy many more days of bright sunlight, an...

A novel wavelet neural network based pathological stage detection technique for an oral precancerous condition.

AIM To describe a novel neural network based oral precancer (oral submucous fibrosis; OSF) stage detection method. METHOD The wavelet coefficients of transmission electron microscopy images of collagen fibres from normal oral submucosa and OSF tissues were used to choose the feature vector which, in turn, was used to train the artificial neural network. RESULTS The trained network was able ...
