Update--noise induced hearing loss and the military environment.

Although Noise Induced Hearing Loss (NIHL) is well recognised there are an increasing number of associations that are important in its study and to a lesser extent in clinical practice. For many there is controversy over whether there is a causal relationship or a confounding effect but of these presbyacusis is the most important. The PULHHEEMS assessment H3 is currently the first level of abnormal hearing. Between H2 and H3 there is a performance decrement and compensation is awarded at levels of NIHL less than H3. If the measurement of NIHL is to be used as a tool in the Army Hearing Conservation Program (AHCP) then the emphasis must be placed on the change from H1 to H2 and not from H2 to H3.

Retrospective analysis of anaesthetics received by patients before susceptibility to malignant hyperpyrexia was recognized.

We have reviewed the anaesthetic histories of patients later found to be susceptible to malignant hyperpyrexia (MH). Many patients known to have this condition have been exposed to the known inducing agents previously, sometimes on more than on occasion. It is clear that insusceptibility to MH cannot be assumed from previous uneventful exposure to the known triggering agents and that all patients suspected of having inherited MH must be screened by in vivo muscle biopsy studies. No common factor could be found to explain this phenomenon.

Calcium and magnesium contents of malignant hyperpyrexia-susceptible human muscle.

The calcium and magnesium contents of muscle obtained by muscle biopsy of patients referred for malignant hyperpyrexia screening were determined. The susceptibility to malignant hyperpyrexia was made on the basis of the halothane contracture test. No difference in cation concentrations was found between the normal and malignant hyperpyrexia-susceptible groups.
