The role of stressful life events in the progress of various skin conditions was studied retrospectively in patients who presented with either psoriasis (where there is some agreement about the importance of stress), urticaria, acne, alopecia and non-atopic eczema (where there is some uncertainty regarding the role of stress), or malignant melanoma, fungal infection, basal cell carcinoma and melanocytic naevi (where stress is considered less relevant). When patients in the three groups were matched for age, those with psoriasis were more likely to report that the experience of stress pre-dated the onset and exacerbations of their condition than patients with other skin diseases. For the psoriasis patients the most common types of life events were family upsets (such as bereavements), and work or school demands, but chronic difficulties were also common. There was no relationship between the severity of stress and time to onset or exacerbations. The results support the notion that stress is more likely to be associated with the onset of psoriasis than other conditions, but also that there may be considerable individual variation in the ability to cope, suggesting that psychological interventions may be helpful for particular patients.

Histopatholgoical analysis of cutaneous lesions in 195 patients with HIV/AIDS was carried out between 1989 to 1997 at tertiary level public hospital in Mumbai. 104/195 (53%) cases showed infectious diseases which comprised of molluscum contagiosum (28), condyloma accuminata (18), verruca vulgaris (7), varicella zoster (5), syphilis (14), tuberculosis (13), donovanosis (4), leprosy (2), chancroid (2), bacillary angiomatosis (2), lymphogranuloma venercum (1), Norwegian scabies (3), leishmaniasis (2), demodicidosis (1), crytococcosis (1), tinea versicolor (1). In 12 (6%) cases neoplasms were observed which included squamous cell carcinoma (9), basal cell carcinoma (2) and kaposi's sarcoma (1) case. The miscellaneous conditions were observed in 66(33.5%) cases which comprised of psoriasis (21), papular urticaria (13), Reiter's disease (7) and eosinophilic folliculitis (6). The prevalence of cutaneous tuberculosis observed in this study is high as compared with western literature while the prevalence of kaposis's sarcoma is quite low as compared with reports from Africa, USA and United Kingdom.

Smoking is the main modifiable cause of disease and death in the developed world. Tobacco consumption is directly linked to cardiovascular disease, chronic bronchitis, and many malignant diseases. Tobacco also has many cutaneous effects, most of which are harmful. Smoking is closely associated with several dermatologic diseases such as psoriasis, pustulosis palmoplantaris, hidrosadenitis suppurativa, and systemic and discoid lupus erythematosus, as well as cancers such as those of the lip, oral cavity, and anogenital region. A more debatable relationship exists with melanoma, squamous cell carcinoma of the skin, basal cell carcinoma, and acne. In contrast, smoking seems to protect against mouth sores, rosacea, labial herpes simplex, pemphigus vulgaris, and dermatitis herpetiformis. In addition to the influence of smoking on dermatologic diseases, tobacco consumption is also directly responsible for certain dermatoses such as nicotine stomatitis, black hairy tongue, periodontal disease, and some types of urticaria and contact dermatitis. Furthermore, we should not forget that smoking has cosmetic repercussions such as yellow fingers and fingernails, changes in tooth color, taste and smell disorders, halitosis and hypersalivation, and early development of facial wrinkles.

Methyl aminolevulinate photodynamic therapy (MAL-PDT) is utilized in several countries for the treatment of basal cell carcinoma, but allergic sensitization has been reported by the manufacturer. To the best of our knowledge, we report the first case of urticaria following MAL-PDT in a patient with nevoid basal cell carcinoma syndrome. Prophylactic use of antihistamines may allow continued use of MAL-PDT in this setting.
