Abstract
OBJECTIVE To evaluate the role of Ureaplasma urealyticum (Uu) in the pathogenesis of Reiter's syndrome (RS). METHODS Infection with Uu was determined in 31 patients with RS and 28 patients with other arthritides by urethral, cervical and synovial fluid (SF) culture and by measuring anti-Uu serum antibody. Infection with Chlamydia trachomatis was determined by examining SF by a direct immunofluorescence technique, by a polymerase chain reaction and by measuring anti-C. trachomatis serum antibody. The proliferative response of SF and peripheral blood mononuclear cells (PBMC) to Uu antigens in patients with RS was compared to that of a control group. The effect that treatment of 6 patients with RS with ciprofloxacin had on repeated cultures, on titer of anti-Uu antibody and on mononuclear cell reactivity was measured sequentially. RESULTS The colonization rate of Uu in patients with RS (74%) was significantly greater than in patients with other arthritides (14%). Genital C. trachomatis isolation and serum anti-C. trachomatis antibody were uncommon in both groups (11 and 13%, respectively). SF mononuclear cells of the patients with RS proliferated specifically in response to Uu antigens [up to 6.9 stimulation index (SI)], as did their PBMC (up to 14.5 SI). In some patients, high anti-Uu antibody titers were measured in the serum. Clinical remission was observed in 4 of 6 patients and correlated with eradication of Uu, decrease in antibody titers and disappearance of mononuclear cell reactivity to Uu antigens. CONCLUSION Our findings suggest that Uu might be a causative agent or a trigger in the development of sexually acquired RS.

Abstract
As nursing moves towards a holistic approach to care, its publications on sexuality have proliferated. 'Sexuality' and 'Gender' are concepts which are extremely difficult to define. While sex refers to the physical differences of the body, gender concerns the psychological and sociocultural differences between females and males. This distinction between sex and gender is fundamental, since many differences between females and males are not biological in origin. And, when a person's gender and sex fall together in accordance with social norms, it may not necessarily be a similar correlation for every individual. The nature of these similarities is essentially threefold. First, Thomas, Savage and Webb accept that there should be a nursing definition of sexuality. In different ways they acknowledge and refer to it as an integral part of a person's being and self concept. Secondly, the authors underline some of the complexities and difficulties nurses have defining and dealing with it in professional relationships as well as on the level of self reflection, knowledge, attitudes and beliefs. Thirdly, all three surveys show why such difficulties prevail, and go on to make suggestions for change in nursing interventions and training. This article summarizes these contributions and discusses the ethical problems which nurses face in dealing with the sexuality of their patients.

Abstract
The structural changes of the silicate framework in hydrated layers of silicate electrode glasses compared with untreated glasses as well as the quality and quantity of water and its ionic species stored in the layer have been investigated by high-resolution solid-state nuclear magnetic resonance (NMR) techniques [29Si magic-angle spinning (MAS), 29Si cross-polarization (CP) MAS, 1H high-speed MAS, 1H CRAMPS and 1H Echo NMR]. To support the results, infrared (IR) spectroscopy, thermal analysis and sodium ion concentration analyses were used. It was found that at least two different water species exist in the hydrated layer: SiOH groups and not very mobile hydrogen-bonded molecular water. Concerning the framework modified, Q3 groups [(SiO)3SiOH] were formed in the hydrated glass. During the swelling process a condensation of silanol groups formed took place to a great extent.

Abstract
The effect of protein tyrosine kinase (PTK) inhibition on spontaneously hypertensive rat vascular smooth muscle contraction was examined in this study. By using isolated aortic strips, it was found that platelet-derived growth factor (PDGF) (0.1-1 nM), an activator of PTKs, elicited contraction with an EC50 of 0.25 +/- 0.08 nM. Treatment with tyrphostin (0.02-200 microM), a selective inhibitor of PTKs, caused a significant rightward shift of the concentration-response curves (P < .05). The IC50 for tyrphostin in the spontaneously hypertensive rat was calculated to be 9.5 +/- 4.2 microM. Tyrphostin also inhibited contractile activity in normotensive control Wistar-Kyoto rat aorta with an IC50 of 0.24 +/- 0.09 microM. Tyrphostin inhibited PDGF-induced contraction over a range of calcium concentrations, suggesting that it may oppose contraction through inhibition of calcium influx via PDGF-induced receptor-operated channel. However, KCl-mediated voltage-operated calcium channels were largely unaffected by tyrphostin, because it was unable to relax aortae which had been partially depolarized. Tyrphostin also had no significant antagonistic effect on contraction induced by phenylephrine or phorbol-12,13-dibutyrate. For both of these agents, contraction is mediated through activation of protein kinase C, which further alludes to the specificity of tyrphostin for PTKs. Treatment with 1 nM PDGF caused a significant stimulation of particulate/membrane PTK activity in the aorta. Tyrphostin attenuated PDGF-induced PTK activity in a concentration-dependent manner. The data suggest that PTKs may play a role in vascular smooth muscle contraction and that specific inhibition of PTK activity results in vasorelaxation. Furthermore, the results suggest that vasoconstriction and vascular smooth muscle cell proliferation may share common biochemical signalling pathways.

Abstract
Eccrine spiradenoma is a benign tumour originating from cutaneous sweat glands. It rarely develops into a malignant tumour. A long-standing cutaneous nodule begins to enlarge rapidly. The growth is often associated with an ulceration and a change in colour. The definitive diagnosis is made after a biopsy with examination of the entire specimen in search for foci of malignant development. The appropriate therapy consists in a wide local excision, with resection of the clinically suspicious lymph nodes. Irradiation of the resection site can be useful to prevent local recurrences. The role of chemotherapy is not yet clearly defined.

Abstract
The objective of this study was to examine diabetic patients at the time of admission to maintenance haemodialysis and to follow them for 36 months in order to define predictors of cardiovascular and non-cardiovascular death. This prospective study comprised all consecutive diabetic patients admitted to 28 German dialysis centres between January 1985 and October 1987; 196 patients were examined, 67 Type 1 (insulin-dependent) diabetic (43 male, 24 female; median age 49 years, range 22-73) and 129 Type 2 (non-insulin-dependent) diabetic patients (54 male, 75 female; 64 years, range 37-82). Outcome measures were death, i.e. myocardial infarction, sudden death, cardiac death of other causes, stroke and non-cardiovascular death. Actuarial survival 36 months after the beginning of dialysis was similar in Type 1 (40%) and Type 2 diabetic patients (43%) despite the age difference. Causes of death were myocardial infarction (18%), sudden death (18%), other cardiac causes (18%); stroke (6%); septicaemia (17%) mostly originating from diabetic foot problems; and interruption of therapy. Survival rates and the proportion dying from cardiac causes were similar in patients with diabetic nephropathy or with other primary chronic renal disease and coincidental diabetes. On dialysis, de novo amaurosis or de novo amputation was not observed in any patient. The strongest predictor of myocardial infarction or sudden death was serum lipids on admission. Duration of hypertension, blood pressure at the time of admission to dialysis, left ventricular hypertrophy or end-diastolic diameter by echocardiography, Sokolow index and average predialysis blood pressure, smoking, interdialytic weight gain and type of dialysis were not predictive of cardiovascular death or death by all causes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Inpatient psychiatric care is changing. Users of mental health services are overwhelmingly in support of hospital closure (Rogers et al, 1993). Many professionals agree that the inpatient approach to care is outmoded and inappropriate for people with acute mental health problems. For example, Murphy (1991) suggested that the majority of people with acute mental disorder can be treated at home if sufficient staff are available to provide adequate support and supervise medication.

Abstract
When unlimited supplies of biosynthetic human growth hormone (hGH) became available in the late 1980s, the envisaged potential of its therapeutic applications was enormous in that it was hoped that perhaps most short children would be able to be made taller. However, this seems to have been far too simplistic a view and certainly in those children with various growth disorders treated with pharmacological doses of growth hormone (GH), the potential for increased final height does not appear to be fulfilled, with the exception of girls with Turner's syndrome. Further challenges in the growth field involve the manipulation of pubertal development during concomitant GH therapy.

Abstract
OBJECTIVE To describe the epidemiology of presenile Alzheimer's disease in Scotland from 1974 to 1988. DESIGN Retrospective review of hospital records of patients aged less than 73 years admitted to psychiatric hospital with various diagnoses of dementia. Diagnoses were classified by National Institute for Communicative Disorders and Stroke and Alzheimer's Disease and Related Disorders Association Criteria and the Hachinski score. Completeness of the study sample was evaluated by scrutiny of neurology outpatient and general hospital records. SETTING All general psychiatric hospitals in Scotland. SUBJECTS All patients with onset of dementia aged 40-64. MAIN OUTCOME MEASURES Probable and broad Alzheimer's disease, sex of patient, age at onset. RESULTS 5874 psychiatric hospital records, 129 neurology outpatient records, and 89 records from non-psychiatric hospitals were examined. 317 patients met criteria for probable Alzheimer's disease, 569 met criteria for broad Alzheimer's disease, and 267 met those for multi-infarct dementia. Minimal incidences per 100,000 population aged 40-64 years were 22.6 (95% confidence interval, 20.2 to 25.2) and 40.5 (38.9 to 42.3) per 100,000 for probable and broad Alzheimer's disease. In the 1981 census year the annual incidence of probable Alzheimer's disease was 1.6 (1.0 to 2.6). Women were at greater risk with incidence rates for probable Alzheimer's disease of 28.2 (24.5 to 32.4) per 100,000 compared with 16.5 (13.8 to 19.8) per 100,000 for men. The incidence per 100,000 for multi-infarct dementia was greater in men (25.1, 23.3 to 27.1) than women (13.4, 12.1 to 14.8). CONCLUSION Female sex seems to be positively associated with development of Alzheimer's disease before age 65 years.

Abstract
The role of protein tyrosine kinases (PTKs) in vascular smooth muscle (VSM) contraction was examined in spontaneously hypertensive rats (SHRs). Aorta from SHRs was hyperresponsive to PTK-mediated contraction relative to normotensive Wistar-Kyoto rats (WKYs). Aorta from SHR was also hyporesponsive to vasorelaxation by tyrphostin, a selective inhibitor of PTKs. Further, we found alterations in PTK activity in aorta from SHRs. PDGF stimulated PTK activity to a greater extent in the SHR. Tyrphostin inhibited PDGF-induced PTK stimulation in both strains, however, activity returned to basal levels in the WKY only. The results suggest that PTKs may be involved in VSM contraction and in the development of hypertension.

Abstract
The objective of this study was to measure cholesterol concentrations in diabetic patients at the beginning of maintenance hemodialysis treatment and to define their role as predictors of subsequent cardiac death on maintenance hemodialysis. The design of this study consisted of a prospective study of all consecutive diabetic patients newly admitted to 28 German dialysis centers between January 1985 and October 1987. The patients were examined on admission and subsequently followed for 45 months on dialysis. This study included 196 patients, 67 type I (43 male, 24 female, median age 49 years, range 22-73) and 129 type II (54 male, 75 female, aged 64 years, range 37-82). Lipids (total cholesterol, triglycerides low-density lipoprotein (LDL) cholesterol high-density lipoprotein (HDL) cholesterol apolipoprotein B and A and anthropometric indices (body mass index, triceps skinfold thickness) were measured. The outcome was death, i.e., cardiovascular (myocardial infarction, sudden death, other cardiac causes, stroke) and noncardiovascular death during a 45-month follow-up. At the start of treatment, total cholesterol, triglycerides LDL cholesterol, LDL/HDL ratio and apolipoprotein B were significantly higher in diabetics than in healthy controls or patients with standard primary renal disease starting dialysis. Only minor differences were found between males and females and type I and type II diabetics. Fourty-three percent of type I and 50% of type II diabetics died, 61% from cardiovascular causes, mostly myocardial infarction (in 40% reinfarction) and sudden death. On admission, diabetics subsequently dying from myocardial infarction had significantly higher median cholesterol than survivors, i.e., 259 versus 222 mg/dl, and higher LDL cholesterol, LDL/HDL ratio and apolipoprotein B.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Until recently, nursing literature had not addressed feminist issues and nurse educators have had little experience in programs of women's studies. The author discusses some implications for nurse educators as they relate to the new scholarship of women and a new consciousness of women's health. Factors contributing to the need for particular ways of teaching when dealing with women as students and with women's health experiences as subject matter are addressed. Using specific examples from her experience in teaching an open enrollment course in women's health, the author describes the use of some feminist pedagogical approaches and the students' response to them.

Abstract
Infection of Escherichia coli with phage T4 gene 2am was used to transport 3H-labeled linear duplex DNA into cells to follow its degradation in relation to the cellular genotype. In wild-type cells, 49% of the DNA was made acid soluble within 60 min; in recB or recC cells, only about 5% of the DNA was made acid soluble. Remarkably, in recD cells about 25% of the DNA was rendered acid soluble. The DNA degradation in recD cells depended on intact recB and recC genes. The degradation in recD cells was largely decreased by mutations in recJ (which eliminates the 5' single-strand-specific exonuclease coded by this gene) or xonA (which abolishes the 3' single-strand-specific exonuclease I). In a recD recJ xonA triple mutant, the degradation of linear duplex DNA was roughly at the level of a recB mutant. Results similar to those with the set of recD strains were also obtained with a recC++ mutant (in which the RecD protein is intact but does not function) and its recJ, xonA, and recJ xonA derivatives. The observations provide evidence for a recBC-dependent DNA-unwinding activity that renders unwound DNA susceptible to exonucleolytic degradation. It is proposed that the DNA-unwinding activity causes the efficient recombination, DNA repair, and SOS induction (after application of nalidixic acid) in recD mutants. The RecBC helicase indirectly detected here may have a central function in Chi-dependent recombination and in the recombinational repair of double-strand breaks by the RecBCD pathway.

Abstract
In Scotland the Information and Statistics Division of the Scottish Office Home and Health Department maintains a computerised record of patients who have been admitted to, discharged from or have died in Scottish mental hospitals. This data source is of particular value to those involved in planning health care provision and to epidemiologists. The present study assesses the quality of these data in relation to patients with verified presenile dementia who have been discharged from the Royal Edinburgh Hospital between 1974 and 1988. Seventeen per cent of presenile patients were not identified and 23% of patients were wrongly classified. More than 93% of patients with presenile Alzheimer's disease were identified, though often under a variety of other diagnostic codes. These findings highlight limitations of the data supplied and suggest that the usefulness of this enviable and unique data source could be enhanced if the medical profession took greater care in clearly stating an International Classification of Diseases diagnosis in a patient's hospital record.

Abstract
A photoperiodically sensitive cultivar of barley (Hordeum vulgare L. Shabet) (BMDR-8) and an isogenic, single-gene recessive mutant of this genotype that is insensitive to photoperiod (BMDR-1) were grown under continuous cool white light with or without supplemental far-red fluorescent light. BMDR-1 initiates flowers 6 days after germination, irrespective of light treatment, whereas BMDR-8 remains vegetative for at least a week longer, even in continuous light. When far-red light is added, the delay of flowering in BMDR-8 is overcome and both genotypes initiate floral primordia at the same time. Total phenol extracted proteins of seedlings of both genotypes were resolved by two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis. No protein differences were found between the genotypes when isoelectric focusing gels were run in the first dimension. Two qualitative genotypic differences were found when nonequilibrium pH gradient gel electrophoresis was run in the first dimension. An 85-kilodalton polypeptide (A) and a 26-kilodalton polypeptide (B) were always present in BMDR-8 but never found in BMDR-1. The levels of A appeared to decrease from the BMDR-8 during the first 3 days of far-red treatment but did not disappear completely even after 6 days of growth in the presence of farred. Polypeptide B decreases rapidly in continuous cool white light but is stabilized by far-red. The phytochrome content of BMDR-1 was found to be greater than that for BMDR-8. This increase appears to be caused by the type I (etiolated-tissue abundant) phytochrome pool, even in plants grown in continuous light.

Abstract
During a study of women with laparoscopically investigated pelvic pain, genital tract specimens were examined for Chlamydia trachomatis using a direct fluorescent antibody (DFA) technique (MicroTrak, Syva) and culture. Some smears, particularly those from the upper genital tract, contained an inadequate number of cells when examined by the DFA technique and many cell monolayers were destroyed by the specimens. To obtain results for such samples, or to confirm the original DFA result, additional specimens which had been frozen at -70 degrees C or in liquid nitrogen were centrifuged at high speed and the resulting deposit examined by the DFA technique. By this means, 32 negative results were confirmed for specimens from 10 chlamydia-negative patients with pelvic inflammatory disease or with high chlamydial antibody titres, and 26 negative results were confirmed for 19 patients who were positive at other sites. In addition, three chlamydia-positive and six chlamydia-negative results were obtained for sites where the original smear for DFA testing had been inadequate (few epithelial cells) and six specimens that were negative originally were found to be positive. Thus, of 73 specimens that were either inadequate or negative by DFA testing originally, 9 (12%) were positive by DFA testing after centrifugation.

Abstract
Postoperative levels of steroid hormones have been measured in lymph and blood of 28 patients undergoing iridium implants as part of conservative treatment for operable breast cancer. The aim was to establish whether there were higher levels of hormones in lymph draining from necrosing tumour cells compared with peripheral blood levels. No differences were found in the ratios of estradiol, dehydroxyepiandrosterone sulphate or sex hormone-binding globulin in those patients with complete compared with incomplete excision of the primary tumour. However, premenopausal patients who had an incompletely excised primary tumour had increased levels of free testosterone in lymph draining from the tumour site on the third and fourth postoperative days. Thus androgens may have an important role in the intracellular metabolism of some breast cancers.

Abstract
"Patterns of marriage between Protestants and Roman Catholics in Switzerland during 1969-72 and 1979-82 are investigated using magnitudes of marriage attraction, measures that reflect the propensity to marry independent of population composition. The results show high levels of intermarriage, with religious differences becoming less salient in marriage choice. There is no evidence that the propensity to intermarry is influenced by 'minority group' effects." (SUMMARY IN FRE)

Abstract
The efficacy of ofloxacin was compared with that of doxycycline in the treatment of non-gonococcal urethritis (NGU) and cervical chlamydial infection in an open randomized study. In total, 182 men and 100 women were enrolled: 92 men and 50 women received ofloxacin at a dose of 400 mg once daily for seven days, and 90 men and 50 women received doxycycline at a dose of 100 mg twice daily for seven days. All women and 42 men, that is 29 men in the ofloxacin group (32%) and 13 in the doxycycline group (14%) were chlamydia-positive on entry into the study. Patients were reviewed on completion of the treatment course (day 8) and two weeks later (day 22). Clinical cure rates for NGU in assessable patients in each treatment group were similar; 73% in the ofloxacin group and 63% in the doxycycline group at day 8, and 70% and 90% in the respective treatment groups on study completion. Repeat tests for chlamydiae were negative for all male and female patients at both day 8 and day 22. Both ofloxacin and doxycycline were well tolerated. We conclude that ofloxacin given at a dose of 400 mg once daily for seven days is a safe and effective alternative treatment for NGU and cervical chlamydial infection.
