The Johannesburg Hospital mobile anaesthesia service.
At a teaching hospital such as the Johannesburg Hospital with an air ambulance service, the need may arise for the administration of an anaesthetic outside the hospital. The occurrence of just such an event prompted the authors to review the literature regarding anaesthesia in adverse circumstances and to assemble, in a portable container, the equipment and drugs considered necessary to cope with the situation. In addition, the responsible anaesthetic personnel are receiving training in the use of the equipment and techniques required.
Genetic disorders of the skin and eye.
This article discusses some of the most uncommon diseases ever seen by the ophthalmologist or dermatologist. Some of these conditions can cause irreparable eye damage if not recognized and treated early after their inception.

Skin signs in pulmonary disease.
We have described many of the cutaneous findings that can be associated with pulmonary disease. Some, such as the vascular reaction patterns, are quite common. Others, particularly those related to the genetic disorders are rather seldom seen. Our intent, however, is to show how recognition of cutaneous markers can assist the internist in caring for their patients with pulmonary disease.
Birthmarks with serious medical significance: nevocullular nevi, sebaceous nevi, and multiple café au lait spots.
Birthmarks of potential medical significance were identified among 4,641 newborn infants: 1.1% had a nevocellular nevus and 0.3% had a sebaceous nevus; 1.8% of black infants, but no white infants, had three or more café au lait spots. The large nevocellular nevus is considered premalignant, but the significance of the small nevocellular nevus has not been established. The sebaceous nevus fades after birth but undergoes hyperplasia at puberty. Multiple café au lait spots occur less commonly in white than in black infants, and are therefore of greater concern as possibly an early sign of neurofibromatosis.
Infant with abnormal pigmentation, malformations, and immune deficiency.
An infant had swirling hyperpigmentation, streaks of hypopigmentation, abnormal T-cell function, cleft palate, patent ductus arteriosus, and arrhinencephaly. This pattern of abnormalities is distinct from other disorders with abnormal pigmentation and malformations; such as incontinentia pigmenti, incontinentia pigmenti achromians, and the epidermal nevus syndrome.
