Battered women and the myth of masochism.

Domestic violence is a major health issue. Research on this problem is just in its infancy. It remains a problem because there has been widespread acceptance of violence in our culture as a means of solving and dealing with problems. Women have been the targets. Waites admonishes health professionals to stop using the concept of masochism as an explanation for abusive behavior. She asks instead for us to look at female motivation in terms of the actual choices that are available and the realistic consequences of these choices. Perhaps only then will health professionals become able to break the cycle of violence and intervene in a way that stops the woman from becoming another homicide statistic.

Scabies in an AIDS hospice unit.

Scabies may cause severe problems in immunocompromised persons. Three case histories are presented which illustrate these problems in people with advanced AIDS. Recommendations for treatment and management are made, with a comment about the need for a high level of suspicion about any atypical rash in an immunocompromised patient.

Automated image segmentation and serial section reconstruction in microscopy.

A technique for automatic 3-D reconstruction of specifically stained features in televised serial histological sections has been developed using an image analyser. Images which included these features were individually converted to binary images, compiled, displayed to show the 3-D morphology and used to quantify the structure. The criteria necessary for producing valid reconstructions and the problems associated with the manipulation of images of fine detail, particularly those containing several thousand features, are illustrated by examples from skin.

Burnout. Symptoms, causes, prevention.

Burnout is costly to the employees who experience it, their employers, and their patients. Individuals who leave nursing waste their education; those who stay pay a psychological price. The organization loses talent and gains poor performance from its employees. Patients lose quality care. As a health professional, listen to your body and mind, become aware of the danger signals, and acknowledge your feelings. Burnout, if diagnosed, can be diminished through careful planning, intervention, and evaluation of your personal and professional life.

Three dimensional structure of the Leishmania amastigote as revealed by computer-aided reconstruction from serial sections.

Computer-aided reconstruction from serial sections has been used to analyse the 3-dimensional structure of entire amastigotes of Leishmania mexicana and to determine the number, arrangement and volume of each organelle. In two reconstructions, the lysosome-like 'megasomes' were the most numerous organelle, there being 34 in one amastigote, and they comprised as much as 15% of the total cell volume. In contrast, as few as 9 glycosomes were present, accounting for less than 1% of the cell volume. The unitary nature of the mitochondrion was confirmed and its complex basket-like structure was revealed. The spatial arrangement of the cell organelles is here displayed in stereo-pairs.

Comparative studies of the ultrastructure of the sebaceous gland.

Three-dimensional reconstructions and ultrastructural evidence on the sebaceous glands of man and domestic animals indicate that sebum is produced from a column of developing and degenerating cell populations derived from peripheral progenitor cells at the base of the lobe in a manner analogous to hair growth. The remainder of the peripheral cells apparently have no direct involvement with sebocyte production; those towards the neck of the gland contribute keratin to the secretory product.

A semi-automatic method of measuring leucocyte movement.

A semi-automatic system has been developed for measuring the migration of leucocytes within a micropore filter. The distance in micrometers is displayed digitally or analysed on-line by a digital computer. These improvements have resulted in considerable saving in time, permitting the full potential of the micropore method to be utilised. To illustrate this technique we report results from experiments to measure dose-response relationships of leucocytes to casein and the variation in response to Staphylococcus aureus and casein of cells from normal human subjects.

An interface to input analogue signals to a digital computer.

An electrical control unit is described which permits analogue signals from most sources to be made compatible with, and optimise the use of, an A/D converter. This circuitry enables the signal to be offset, relative to the electrical zero, and to be reset to zero using a push button. Extension of this unit has enabled mechanical movement, such as rotation of a shaft, to be measured. In order to make the most efficient use of the A/D converter the gain of the output can be varied.
