[What are the epidemiological data on the consequences of smoking-related increased risk in pregnant women? Dermatological consequences].

Smoking has numerous effects on skin. Some of them are well established, others are more debatable. Smoking is a cofactor of skin aging after chronic sun exposure, as demonstrated by recent histological, biochemical and cutaneous relief studies. Smoking is a well established risk factor of cutaneous, mucous membrane cancers, and some gynecologic cancers as well, in some cases increased by pregnancy. However, published studies have included small numbers of subjects. Some skin affections are worsened by smoking, and others might be improved. However scientific data on smoking and skin or pregnancy are both scarce.

[Two complications of bullous emphysema. Apropos of a case].

Infection and cancer are two classical complications of bullous emphysema. We report the case of a 47-year-old patient who presented a tuberculous infection then cancer within less than one year interval. The questions concerning diagnosis of infection are discussed. Pyogenic germs are usually involved and tuberculosis much less often. Exceptionally atypical mycobacteria, notably xenopi, are rarely the cause. The diagnosis can be particularly difficult in case of haemorrhage or cancer on bullae. The diagnosis of cancer in bullous emphysema is also studied. The relationships between tuberculosis and cancer in bullous emphysema are discussed.
