Short communication: effects of a gonadotropin application on seasonal subfertility in pigs.

In this study the reproductive performance of weaned sows in a large production unit was evaluated during periods of high (> 35 degrees C) summer temperatures. Only weaned sows of parity 2-6 (a total of n = 3386) were evaluated in two groups in 13 replicates: Group 1 (n = 1694): The sows were treated subcutaneously with 400 I.U. of Gonadotropinum sericum (pregnant mare serum gonadotropin, PMSG [eCG]) and 200 I.U. of Gonadotropinum chorionicum (human choriongonadotropin, HCG [hCG]) on the day of weaning. Group 2: (n=1692). The sows received subcutaneously 4 ml of physiological NaCl solution on the day of weaning. Weaning to service intervals, regular and irregular returns to service, farrowing rates, and subsequent litter sizes were evaluated. Control sows had longer (P < 0.01) weaning to service intervals and more (P < 0.01) regular returns to service during hot weather periods compared with the gonadotropin treated sows. Irregular returns to service were low and showed no significant differences between the treated and non-treated sows (1.4+/-0.3 % vs. 1.5+/-0.4 %). Farrowing rates and litter sizes were significantly (P < 0.01) better in the treated compared with the non-treated sows.

What is consumerism and has it had an impact on health visiting provision? A literature review.

AIMS: This paper analyses the concept of consumerism drawing on methods of concept analysis. It attempts to identify who the actual consumers of health visiting are before examining whether consumerism and the consumer's voice has had an impact on health visiting provision. BACKGROUND: Patients and clients are increasingly being referred to as consumers, but the term seems to be used simply as substitute for patient, client or service user. Consumerism is a complex concept and the extent of its usage in the context of health visiting has not been fully explored. METHOD: An integrative review of a range of literature relating to consumerism is presented. A focused analysis of consumer views of child health clinics is used to illustrate the concept of consumerism. Elements of concept analysis methods such as formulating a model case and a definition are used to illustrate the concept further. RESULTS: The review suggests that consumerism is an outdated concept and has been replaced by other less emotive terms such as partnership and participation. The apparent lack of impact of consumerism research in health visiting is argued by examining empirical evidence relating to child health clinics. CONCLUSIONS: Consumerism has had relatively little impact on improving child health clinics although high levels of consumer satisfaction with the overall service exist. More methodologically sound studies are needed to explore users' views of health visiting services and to implement findings to maintain or improve services.

Constipation: a family-centred approach.

Constipation in childhood is a common problem, causing great concern to parents. Palo Almond describes the problem, its management and the medical, social and psychological issues involved. Greater health visitor input could result in fewer referrals to the consultant paediatrician for treatment, she suggests.

Effects of filters and wedges on skin sparing and gamma/neutron dose ratios in neutron teletherapy.

The effects of skin sparing and the gamma/neutron dose ratios in the clinical situations presently in use at the TAMVEC neutron teletherapy facility are not appreciably affected by the presence of filters and/or wedges. It is also shown that if skin sparing is lost due to close proximity of a hydrogenous scattering source, it can be restored by the use of thin lead filters.

Quality assurance in brachytherapy: the role of the ICRU in achieving uniformity in dose and volume specification for reporting.

A quality assurance programme in brachytherapy implies a general consensus on the method of dose and volume specification for reporting. This in turn implies a consensus on certain definitions of terms and concepts. For several decades, the ICRU (International Commission on Radiation Units and Measurements) has been actively involved in an effort to reach a consensus between different brachytherapy centres worldwide, and to improve uniformity in reporting. The ICRU has prepared two reports containing recommendations for reporting brachytherapy treatments. The first, report #38 published in 1985, deals with intracavitary therapy in gynecology. The second deals with interstitial therapy, and is now in press. A summary of these two ICRU reports is presented here. Some definitions of terms and concepts are first recalled and discussed: Total Reference Air Kerma (TRAK), gross tumor volume (GTV), clinical target volume (CTV), treated volume, mean central dose, dose uniformity parameters, etc. Specific recommendations for reporting interstitial and intracavitary brachytherapy are then presented.
