Overseas Occupational Therapists in Australia: the Issue of Recognition

The Australian government established the Council on Overseas Professional Qualifications (COPQ) in 1969. In response to approaches by the occupational therapy profession, an Expert Panel in Occupational Therapy was established in 1979 in order to develop a screening examination to be used in assessing the competency of overseas trained occupational therapists. This paper describes the development of the COPQ examination for all overseas qualified occupational therapists wishing to work in Australia; the experience of candidates since its inception in 1983; and the problems associated with achieving recognition of the COPQ examination throughout Australia given the lack of uniform recognition procedures in the various States and Territories. The need for a consistent national approach to the policy of recognition and employment of overseas trained occupational therapists is addressed, with stress placed on the need for all employer groups, in both the public and the private sectors, to cooperate with COPQ's assessment procedures.     

International Family-planning Training for Nurse Practitioners

Since the mid-1970s, the Margaret Sanger Center of Planned Parenthood of New York City has prepared nurses and nurse midwives from less developed countries to be family-planning nurse practitioners. These nurse practitioners then provide services to patients, train other staff, and manage integrated family-planning clinics. More than 120 nurses and nurse midwives have arrived in groups of 10 at the Sanger Center, with 72 attending since 1981. Each course lasts 10 weeks. The core curriculum provides trainees with skills in women's health care including contraception, in training and advocacy, and in management of clinics. Whether, in the current period of scarce resources, cross-cultural training programs of this type remain a worthwhile investment, and if so, which of their components are most important to this success, is assessed.     

Variation in Mortality from Ischaemic Heart Disease between England and Scotland

A Comparison of mortality from ischaemic heart disease underthe age of 60 for 1980 to 1981 between the Grampian Health Boardand the North Staffordshire Health Authority has been made.A total of 993 deaths was notified by death certificate fromthe two areas of similar population of which 434 were from Grampianand 559 from North Staffordshire. After examination of generalpractitioner and hospital case notes, autopsy reports and deathcertificates, nearly all (532) of the North Staffordshire deathswere accepted as being due to ischaemic heart disease but onlythree-fifths (263) of the Grampian deaths could be begin besubstantiated as there was inadequate information for the remainder.Deaths from ischaemic heart disease seem apparently to be twofoldgreater in North Staffordshire than Grampian but much of thisdiscrepancy could be attributed to a widely different autopsyrate and to unavailability of case notes. Experience of thissurvey suggests that the results of other epidemiological investigationsmay be equally or even more unreliable.     

Influencing physician response to prenatal substance exposure through state legislation and work-place policies

Little research attention has focused on ways to encourage physician response to prenatal substance exposure. We report initial results from a study examining the impact of state laws and work-place policies on physician response by combining legal analyses and data from a national physician survey. Our findings indicate that the message that laws and policies exist usually does not reach physicians. However, when the message does come through, some physician behaviors are influenced. In particular, physicians in states with clearer policies and behavioral expectations are significantly more likely to know and understand the law than physicians in other states. Further, believing that a work-place protocol on prenatal substance exposure exists is associated with significantly increased likelihood of an active response in case vignettes portraying prenatal substance exposure. The findings suggest that state legislative behaviors may increase physician response to prenatal substance exposure, but that response depends on the nature of the policy and on efforts to disseminate it.     

Antigen Presentation By Class I Major Histocompatibility Complex Molecules: A Context for Thinking About HLA-G

PROBLEM: There is substantial data that support the efficacy of paternal leukocyte immunization (PLI) for the treatment of alloimmune mediated miscarriage; however, there is confusion regarding the laboratory test that should be performed to determine levels of maternal anti-paternal leukocyte antibodies (MAPLA). METHOD: Popular methodologies employed include: 1) microcytotoxicity (MCX), 2) mixed lymphocyte culture (MLC), and 3) cell flow cytometry crossmatch (FCXM). Cell flow cytometry crossmatch correlates well with the more difficult MLC assay although the former proves the more sensitive study. This work compares the MCX assays with FCXM. The study group consisted of ten women who had a history of three or more spontaneous abortions (SABs). All ten had very low levels (<10%) of MAPLA as measured by FCXM. Following PLI all subjects demonstrated elevated levels (>50%) of MAPLA by FCXM. At 12 weeks gestation, sera were simultaneously measured for MAPLA by MCX and FCXM. RESULTS: Although all ten patients had very high levels of MAPLA by FCXM during pregnancy, five of ten had antibodies to HLA Class I and two of ten had antibodies to HLA Class II paternal antigens by MCX. Furthermore, all patients who were positive by MCX to paternal Class I antigens were also positive to Class I antigens not seen in either parent. Both patients who were positive by MCX to paternal Class II antigens were also positive to maternal Class II antigens. Notable is that all ten women eventually delivered healthy infants. CONCLUSION: Based on this preliminary study, the MCX assay is neither sensitive or reliable enough to determine the need and/or to monitor the effectiveness of PLI. Flow cytometry should be the modality of choice when determining the need for alloimmunotherapy and to monitor the effectiveness of treatment.     

Decision making in diagnostic radiology

Radiology can be more interesting if the principles of decision making are understood and used to the advantage of the radiologist, referring clinician and patient. This article seeks to revise the principles that radiologists use intuitively. Particular emphasis is placed on the importance of the pre-test probability, as it can be shown to: (i) vary with the referral pool of patients; (ii) be a major determinant of the amount of additional information gained from the test; (iii) alter the sensitivity and specificity of the test; and (iv) determine largely the significance of a positive or negative test result. An investigation helps a clinician by providing information that will move the probability of disease above an action threshold or below its exclusion threshold. If this does not occur as a result of one study, another is selected. This article also describes the factors involved in such a decision tree analysis, as well as discussing the reasons for both selecting a particular examination and deciding when a test should not be performed.     

Four unusual cases of Spinal Cord Compression

Four cases of spinal cord compression are presented, the causes being tuberculoma, haemangioma, gouty tophus and exophytic glioma; the first three being extradural, extraosseous in location. A short discussion follows. These cases are presented to remind the reader to keep less common causes in mind when dealing with a case of spinal cord compression.
