Mourning Bit by Bit

In this piece I describe the process of mourning my mother since her death in 2001, via my short animated documentary ‘Oneironauts – the Dream Travellers’ (2011) and my more recent experiences as the mother of a young baby. I consider my experience in the context of Freud's ‘Mourning and Melancholia’.     

Traumatic infarction of the spinal cord in children

Infarction of the spinal cord in childhood is rarely due to trauma. During a 15-year period (1971 to 1985), eight children were admitted to The Hospital for Sick Children, Toronto, with a diagnosis of traumatic infarction of the spinal cord. All of these patients had delayed onset of neurological signs varying between 2 hours and 4 days after their initial trauma. No bone abnormalities were seen on plain spine x-ray films. Myelography was carried out in seven of these children and found to be normal in all seven. Six patients who were paraplegic at the time of admission remained permanently paraplegic, but two with incomplete cord signs did show some improvement.     

HEALTH STATUS AND HEALTH CARE IN RURAL AUSTRALIA: A CASE STUDY

Knowledge of the health status of, and patterns of health care service utilization by rural Australian communities, is scant. This deficiency limits attempts to formulate policies designed to bring about efficient, effective and equitable delivery of health care services. This article reports the results of a health interview survey conducted in the Wimmera region of Victoria during spring 1984. The results demonstrate not only that patterns of morbidity in rural areas differ from the Australian average, but also that the health status of rural dwellers is worse than that of most Australians. Evidence suggests that while accessibility is not the most significant determinant of utilization of health care services, distance from services does affect propensity to use them.     

Predicting medical students' intentions to take up rural practice after graduation

Objectives Using a novel longitudinal tracking project, this study develops and evaluates the performance of a predictive model and index of rural medical practice intention based on the characteristics of incoming medical students. Methods Medical school entry survey data were obtained from the Medical Schools Outcome Database (MSOD) project implemented in all Australian and New Zealand medical schools and coordinated through Medical Deans Australia and New Zealand, the representative body for the Deans of 18 Australian and two New Zealand medical schools and faculties. The medical school commencement survey collects data on students’ education and family background, including rural upbringing, personal circumstances and scholarships, and on their practice intentions in terms of location and specialty. The MSOD will also allow tracking of medical graduates after graduation. Logistic regression modelling was used to develop a predictive model of rural practice intention. Split‐sample validation was used to gain some insight into the stability of performance of the model. Results Response rates to the MSOD survey exceeded 90% on average. The model findings confirm and extend previous research examining the association of medical student characteristics with intention to take up rural medical practice. The statistically significant independent factors in the model included students’ rural backgrounds, financial arrangements and intentions regarding specialist versus generalist practice upon graduation. Model performance was good, with an area under the receiver‐operator characteristics curve of 0.86, and reproducible, with an area in a validation sample of 0.83. Conclusions The model and related index provide important insights into individual factors associated with rural practice intention among students commencing medical studies. The model can also provide a means for optimising the use of scarce medical programme resources, thereby helping to improve the supply of rural medical practitioners. This study illustrates the power and potential of a robust, consistent, systematic longitudinal tracking project.     

Characterization of a progesterone-binding, three-domain antibody fragment (VH/K) expressed in Escherichia coli.

The heavy chain variable region (VH) and the kappa light chain of the anti-progesterone monoclonal antibody (mAb) DB3, have been expressed as a single-chain three-domain polypeptide, designated VH/K, and secreted into the periplasmic space of Escherichia coli (E. coli). The linker sequence was derived from the VH-CH1 elbow region. The C kappa domain provides a sensitive detection tail for Western blotting and enzyme-linked immunosorbent assay (ELISA). Periplasmic extracts of transformed E. coli contained material that bound progesterone and related steroids with similar specificity and affinity to DB3, and displayed the DB3 idiotype and kappa chain epitopes. Reference to the crystal structure of DB3 suggests that all the characteristics of the combining site interaction with steroids are retained in the bacterially expressed material. Western blotting demonstrated material with a molecular weight equivalent to three domains after reduction, but six domains in the unreduced state, suggesting that the VH/K polypeptide is assembled in the periplasm as a disulphide-bridged dimer. The VH/K construct provides a novel route to expression of antibody combining sites in E. coli for antibody engineering.     

The effect of nedocromil on weal reactions in human skin.

1. Nedocromil 2% iontophoresed into human skin had no effect on wealing produced by intradermal histamine, 48/80 or house dust mite antigen. 2. Iontophoresis of 0.002-2% nedocromil itself resulted in dose-related wealing. 3. This wealing was reduced by 62 +/- 8% s.e. mean by the H1-receptor antagonist terfenadine which decreased histamine wealing by 68 +/- 2% s.e. mean. 4. Nedocromil may therefore act as a weak agonist on a skin mast cell receptor concerned with histamine release.
