Contraception and abortion attitudes and practices of Western Ukraine women.

OBJECTIVES: To assess the attitudes and practices of contraceptive behaviors of Western Ukraine women. METHODS: A survey of 500 women in the Oblast was conducted to assess their knowledge, attitudes and practices on a variety of health topics. Convenience sampling was used to access the subjects in 16 different towns/villages in nine rayons throughout the Oblast. Respondents were asked more than 100 questions pertaining to their knowledge, attitudes and practices on a variety of health topics, including stress, contraception, breast health, sexually transmitted diseases, parity, abortion, nutrition, alcohol and tobacco use, domestic violence, and depression and mental health. RESULTS: Of married women, 44% (112/256) would terminate their pregnancy while 56% (144/256) said they would keep their baby. Of unmarried women, 35% (31/88) would abort while 65% (57/88) would keep their baby. A large proportion of married women (82%; 222/271) and unmarried women (70%; 52/74) did not use condoms at all. CONCLUSION: These results suggest lack of birth control education and contribution to poor protection from sexually transmitted infections. Higher abortion practices may also play a role in the infertility issues that Ukrainian women currently face.     

Use of a violence risk assessment tool in an acute care hospital: effectiveness in identifying violent patients.

This study examined the use and effectiveness of the Alert assessment form. The form is part of the Alert system, used by one large acute care hospital to identify patients with a propensity for violence. All reported incidents of patient violence from August 1, 2003, through December 31, 2004, were included in patient charts. One hundred seventeen violent patient charts were reviewed and compared with 161 non-violent patient charts, randomly chosen from the same time period. Overall use of the Alert assessment form for violent and non-violent patients was 75.7% and 35.4%, respectively. The assessment form was found to have moderate sensitivity (71%) and high specificity (94%). It is reasonably effective in identifying potentially violent or aggressive patients when it is used according to protocol. Efforts to improve the tool are warranted, as is evaluation of its benefit in settings with low prevalence of violence. Also, greater effort must be taken to prevent violence once an aggressive patient has been identified.     

Assessment of cutaneous sensory and autonomic axon reflexes in rheumatoid arthritis.

OBJECTIVE--To assess sensory function in skin overlying the joints of patients with rheumatoid arthritis, in relation to the pain and tenderness which commonly arises in structures not directly involved in the inflammatory process. METHODS--An intradermal injection of capsaicin 0.05 microgram in 10 microliters was made over the wrists and forearms of 40 patients with rheumatoid arthritis and 46 control subjects. Axon reflex vasodilatation was measured using laser Doppler flowmetry. Cholinergic sympathetic function was assessed by measuring axon reflex sweating induced by a single intradermal injection of nicotine 0.5 microgram in 0.1 ml. RESULTS--Capsaicin induced axon reflex vasodilation over the wrists was found to decrease with age in normal subjects (r = -0.62, p < 0.001). In patients with rheumatoid arthritis, capsaicin induced axon reflex vasodilatation was significantly greater over the wrists, but not the forearms, when compared with age matched normal controls (p < 0.01). A minimal correlation between axon reflex vasodilatation and visual analogue pain score was apparent in the rheumatoid group (r = -0.37, p < 0.05). Nicotine induced sweating responses were similar in the rheumatoid and normal groups, and both showed a linear age related decline. CONCLUSIONS--The results show a selective increase of capsaicin induced vasodilatation in skin overlying joints in patients with rheumatoid arthritis. This suggests that the activity of a sub-population of periarticular small sensory fibres is altered, which may explain, at least in part, some of the clinical findings in this disorder.     

Some of the factors to be considered in the prescription and timing of bitewing radiography in the diagnosis and management of dental caries.

This article describes some of the factors to be considered by the practitioner when prescribing bitewing radiographs in the diagnosis and management of dental caries and draws on the literature of a number of disciplines including restorative dentistry, cariology, epidemiology and oral radiology. It seems appropriate to re-assess current practice in the light of information on changes in the disease of dental caries, its behaviour and the way this behaviour may vary in high and low caries risk groups. The diagnostic potential of the bitewing examination appears, at present, to be unrivalled, but other diagnostic methods, such as fibreoptic transillumination and tooth separation, must also be considered. Some methods to minimize radiation doses and increase diagnostic yield are discussed. Current knowledge of prescribing patterns is reviewed and areas of ignorance are mentioned as findings from future research in these areas may influence decisions about when to use and re-use bitewing radiographs.     

Laminin-5-enriched extracellular matrix accelerates angiogenesis and neovascularization in association with ePTFE

The performance of biomedical implant devices is often limited by inappropriate tissue responses associated with synthetic materials used in device construction. Adverse healing responses, in particular the lack of an extensive vascular supply in the peri-implant tissue, are believed to lead to the ultimate failure of many of these medical devices. Accelerated formation of new blood vessels in the peri-implant tissue and within porous polymeric implants is hypothesized to improve the performance of such biomedical implant devices. The current study evaluated the use of cell-mediated, extracellular matrix modification of expanded polytetrafluoroethylene (ePTFE) to increase vessel growth in peri-implant tissue and within the pores of the implants. Discs of ePTFE were modified through cell-mediated matrix deposition using epithelial and endothelial cell lines with variable deposition of collagen types, fibronectin, and laminin types. Cell matrix-modified discs, Matrigel-coated discs, and nonmodified discs were implanted in both the adipose and subcutaneous tissues of the rat. Following a 5-week implant period, samples were removed and evaluated histologically and morphometrically for the presence of blood vessels in the peri-implant tissue and within the pores of the polymer as well as for the presence of activated macrophages and monocytes. A significantly increased presence of activated macrophages and monocytes was associated only with the samples modified with the matrix from a human microvessel endothelial cell line. Increased vessel density was identified in association with those ePTFE samples modified with either the 804-G, HaCaT, or II-4 cell matrices, all of which have extracellular matrices enriched in the protein laminin-5.     

Cancer of the colon in an egg donor: policy repercussions for donor recruitment

This paper describes the tragic case of a young woman who died of cancer of the colon after successfully donating eggs to her younger sister. Although there is no direct link between her operation and the subsequent development of bowel carcinoma, this case imparts a feeling of unease when seen in conjunction with other cases reported during the last few years. It is a reminder that little is known of the long-term consequences of some aspects of assisted conception. Women undergoing ovarian stimulation for themselves or a matched recipient have the right to be advised, in an agreed format, that there is some concern about unproven potential risks from the stimulatory drugs. The safety of egg donors must assume priority over all other considerations, including lack of donors or any moral position. The recent decision by the Human Fertilisation and Embryology Authority (HFEA) to withdraw any form of payment or recompense to egg donors does not seem to us to be based on a balance of scientific advances, patient needs and the ethics of gamete supply. They state that the intention to withdraw payments was implicit in the 1990 Human Fertilisation and Embryology (HFE) Act. However the Act was based on the Warnock report made 6 years earlier. Even in 1990 ovum donation was uncommon and fertility drugs had not yet caused any unease. The Act provided the HFEA with discretionary powers to issue directions so that the future policies would be consistent with any emerging new medical evidence. It is imperative that the HFEA provide convincing evidence on how the current policy of payment to donors harms society, donors or recipients, and how in the UK the new policy will improve medical practice in assisted conception. Successful pilot studies must precede the implementation of any new policy. Failure to do this could cause irreversible harm to the practice of assisted conception using donor gametes, which will ultimately be against the basic aims of the 1990 HFE Act.
