A rare heteromorphism of chromosome 20 and reproductive loss.

A rare centromeric heterochromatic variant of chromosome 20 was encountered during investigations in a couple with repeated miscarriages. The enlarged segment was G and C band positive and stained positively by Giemsa II. In situ hybridisation of the biotinylated alphoid probe D20Z1 specific for the centromere of chromosome 20 to metaphase cells confirmed the presence of amplified sequences adjacent to the centromere. The variant was found to be familial and was evaluated as having no clinical significance.

A review of 20 cases of spastic dysphonia.

Twenty patients with the distinct nosological entity of adductor spastic dysphonia (SD) were seen at St Vincent's Hospital, Sydney over a 6-year period. Nine of these patients also experienced a tremulous voice associated with evidence of an essential tremor (ET) elsewhere, including head, trunk and limbs. The mean age of onset in patients with SD was 45 years and in those with SD with ET was 52 years. In 10 patients the onset was gradual, with the remaining 10 experiencing an abrupt onset, in 3 related to an upper respiratory tract infection and in 7 to psychosocial stress. Factors which frequently resulted in a worsening of speech included stress, public speaking, tiredness, strong emotions, upper respiratory tract infections and prolonged use of the voice. In patients with SD alone temporary relieving factors included spontaneous statements, use of a quiet voice, slow speech, high and low pitch, yawning, chewing, swallowing, laughing and on first waking in the morning. The response to therapy was variable. Two patients underwent recurrent laryngeal nerve sectioning.

Familial paracentric inversion of 1p.

We report a paracentric inversion of 1p in a boy with mild mental retardation. The chromosome aberration was identified by high resolution chromosome banding, and was also present in his phenotypically normal mother and other relatives. The boy's karyotype was considered to be 46,XY,inv(1) (p31,2p36.22) ISCN (1981).

Specialist nurses in Australia: the ICN and international regulation.

This article focuses on the relationship between specialist nurses in Victoria (Australia) and the International Council of Nurses (ICN). A major consideration is whether international standards can be applied across international boundaries. The ICN has represented the worldwide nursing community for the past 100 years. In 1997 the Royal College of Nursing (Australia) gained membership to the ICN and to its Regulation Network. With growing interest about internationalization, a key question is whether Australian nurses will accept the Council recommendations on regulation. In a report on specialist nurse education in Australia, recommendations were made that included the adoption of the ICN definition for specialist practice. A survey of the opinions of 75 nurses practicing in Victoria, toward a selection of recommendations from the report, showed strong agreement on definition and much less agreement on minimum credentials. Findings from the survey are discussed in relation to the international profile that is now expected of specialist nurses in Australia and a potential future role for professional organizations.
