Drug eruptions.

The last four decades have seen an enormous increase in the use of potent and toxic drugs as therapy. The considerable advances that these drugs have provided in the control and prevention of disease are matched by their potential to produce unwanted side effects many of which are reflected in the skin. These side effects cannot in the main be predicted. Tests in animals may not reliably be ext...

Dynamics of Lake Eruptions and Possible Ocean Eruptions

Dissolved gas in liquid is able to power violent eruptions. Two kinds of such gas-driven eruptions are known in nature: explosive volcanic eruptions driven by dissolved H2O in magma at high temperatures and lake eruptions driven by dissolved CO2 in water at low temperatures. There are two known occurrences of lake eruptions, one in 1984 (Lake Monoun) and one in 1986 (Lake Nyos), both in Cameroo...

Drug-Induced Acneiform Eruptions

Acne vulgaris is a chronic skin disease that develops as a result of inflammation of the pilosebaceous unit and its clinical course is accompanied by comedones, papules, pustules, and nodules. A different group of disease, which is clinically similar to acne vulgaris but with a different etiopathogenesis, is called “acneiform eruptions.” In clinical practice, acneiform eruptions are generally t...

Cutaneous drug eruptions.

Patients attending a referral Skin Clinic were studied to identify the spectrum of drug eruptions and the offending drugs. There were 51 patients with an incidence of five per thousand and equal sex incidence. Though the pattern of eruption was broadly similar to other reports, unusual reactions were observed. In addition to the skin manifestation, fever and lymphadenopathy were present in most...
