Haemochromatosis. A personal viewpoint.

BACKGROUND: Hereditary haemochromatosis is an inherited disorder of iron metabolism. It is the commonest inherited disorder in people of Celtic or northern European descent. The early symptoms are nonspecific and the diagnosis is often delayed or missed. Early treatment prevents complications and leads to a normal life expectancy. OBJECTIVE: This article describes the common early symptoms and the initial tests for the detection of haemochromatosis. It also gives the current recommendations for the screening of relatives. DISCUSSION: Patients in the early stages of iron overload are usually seen by general practitioners. An increased awareness of haemochromatosis among doctors will lead to earlier diagnosis and improved outcomes for these patients.

Comfort and safety in eye surgery under local anaesthesia.

The study consisted of two parts: 1. The standard system in use at our hospital for gas delivery under the drapes during eye surgery under local anaesthesia was compared with one incorporating a venturi. 2. The oxygen concentration at the operation site was measured with three methods of draping using the two systems. Twenty-three patients and thirty-one volunteers from the operating room staff were subjected to operating conditions and gas concentrations and certain vital signs measured using both systems. The subjective response of the volunteers, none of whom had blocks or premedication, was noted. The burden of rebreathing seen with a significant proportion of cases using 6 l/min of fresh gas flow was not seen when the venturi system was used. The safety from fire hazard using 26% oxygen and diathermy was demonstrated with occlusive and free draping.
