Epidemiology and eradication of infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) virus in Finland.

BACKGROUND: Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) is a significant disease among domestic and wild cattle. The BHV-1 infection was first detected in Finland in 1970; presumably it was imported in 1968. The infection reappeared in the large-scale bulk-tank milk surveillances which started in 1990, and was eradicated in 1994. Our aim is to describe the epidemiology of this infection in Finland, and its eradication. MATERIALS AND METHODS: The official sources of pertinent information, the legal basis for the disease control and the serological methods for the detection of the infection are described. RESULTS AND CONCLUSION: Ten AI bulls were found to be seropositive in 1970-1971. The total number of herds with BHV-1 antibody positive animals in the large-scale surveillance in 1990 and subsequent epidemiological investigations in 1991 was five, and the total number of seropositive animals was 90. The five herds formed three epidemiological units; semen of at least one bull seropositive in 1971 had been used in each unit. This remained the only plausible route of infection in each of the three units. Using the 'test and slaughter' approach and total stamping out in one herd the infection was eradicated in 1994.

Incontinence after prostatectomy: coping with incontinence after prostate cancer surgery.

PURPOSE/OBJECTIVES: To describe the nature of postprostatectomy urinary incontinence, determine how men manage postsurgery urinary incontinence, identify men's perceptions of adequacy of preoperative counseling, and identify men's expectations regarding the probability of postsurgery incontinence. DESIGN: Survey. SETTING: United States. SAMPLE: Members of US TOO International, who experienced urinary incontinence after surgery. METHODS: Copies of the survey (N = 370) were mailed to all chapters of US TOO International, a prostate cancer support group, for distribution to members. A letter of invitation also was posted on the US TOO International Web site and in the monthly newsletter. Men who desired to complete the survey (N = 130) called the researcher's office, and a copy of the survey and a stamped return envelope was mailed to them. Surveys returned to the researchers from June 1998 to January 1999 were included in the analyses. MAIN RESEARCH VARIABLES: Urinary incontinence, management of urinary incontinence, and coping. FINDINGS: 166 men returned surveys. The majority was Caucasian (95%) and married (83%). The median age was 67 years, 87% of the men rated their health as good or excellent, and 114 men (69%) reported becoming incontinent after surgery. Most men experienced stress incontinence symptoms. The majority (89 of 111 men) reported that they were told preoperatively that urinary incontinence was a possible complication. Overall, regardless of length of time since surgery, men (74%) thought that incontinence was an important problem to resolve. Men used containment devices such as pads, special undergarments, and even sanitary napkins as management strategies. The majority of men (54%) used pelvic muscle exercises, especially those who were fewer than two years postsurgery (72%). CONCLUSIONS: Urinary incontinence is a prevalent postoperative complication for men, even up to five years after surgery, and a source of great distress for some. Men reported stress and urge incontinence symptoms and used an array of strategies to contain their urine. Finding effective treatments for postprostatectomy urinary incontinence and receiving adequate information before surgery is important to these men. IMPLICATIONS FOR NURSING: As the number of men who undergo surgical treatment for prostate cancer increases, nurses need to be equipped with the necessary knowledge and information to answer preoperative concerns and provide effective strategies for managing postoperative urinary incontinence.

Aldicarb poisoning.

Aldicarb (2-methyl-2(methylthio) propanal o-[(methylamino)-carbonyl] oxime) is a pesticide manufactured since 1965. This carbamate ester is sold under the tradename, Temik, and is used as insecticide and nematicide. The Environmental Protection Agency has classified aldicarb in the highest toxicity category and has defined a strict control for its delivery and use. In Brazil and the Caribbean island, aldicarb is illegally used as a household rodenticide with a widespread risk of poisoning. Our study presents the first review of aldicarb poisoning circumstances associated with clinical and analytical findings. Moreover, the oxime treatment is discussed. Eighteen patients with cholinergic symptoms admitted to the Emergency Unit and two deceased with a history of aldicarb poisoning were included in the study. As agricultural workers, only two of them could legally use Temik. Seventy percent of the patients was managed by the Emergency Mobil Unit. Serum cholinesterase activity was always lower than 30% of the normal range and aldicarb was identified by UV spectra and retention time after liquid chromatography separation. The most common muscarinic effect was diarrhea, the main nicotinic sign fasciculation and almost half of the poisoned patients had central nervous system (CNS) depression (Glasgow Coma Score lower than 8). Four patients had serious conduction abnormalities and two of them died. These results suggest that aldicarb intoxication is always severe. Oxime treatment did not produce side effects and should be recommended whenever the pesticide involved is unknown. Effective measures should be implemented to stamp out the illicit use of aldicarb.

Database design to ensure anonymous study of medical errors: a report from the ASIPS Collaborative.

Medical error reporting systems are important information sources for designing strategies to improve the safety of health care. Applied Strategies for Improving Patient Safety (ASIPS) is a multi-institutional, practice-based research project that collects and analyzes data on primary care medical errors and develops interventions to reduce error. The voluntary ASIPS Patient Safety Reporting System captures anonymous and confidential reports of medical errors. Confidential reports, which are quickly de-identified, provide better detail than do anonymous reports; however, concerns exist about the confidentiality of those reports should the database be subject to legal discovery or other security breaches. Standard database elements, for example, serial ID numbers, date/time stamps, and backups, could enable an outsider to link an ASIPS report to a specific medical error. The authors present the design and implementation of a database and administrative system that reduce this risk, facilitate research, and maintain near anonymity of the events, practices, and clinicians.

Evaluation of the predictive value of Her-2/neu overexpression and p53 mutations in high-risk primary breast cancer patients treated with high-dose chemotherapy and autologous stem-cell transplantation.

PURPOSE: To ascertain the predictive value of Her-2/neu overexpression and p53 mutations, assessed by immunohistochemistry, in high-risk primary breast cancer (HRPBC) treated with high-dose chemotherapy (HDCT). PATIENTS AND METHODS: We obtained paraffin-embedded tumor blocks from 146 HRPBC patients previously enrolled at our program onto clinical trials of HDCT for four to nine involved axillary lymph nodes, > or = 10 involved axillary nodes, or inflammatory carcinoma. All patients received the same HDCT regimen, with cyclophosphamide, cisplatin, and carmustine (STAMP-I), followed by autologous stem-cell transplantation. Median follow-up was 42 months (range, 5 to 90 months). The same pathologist, blinded to clinical outcome, reviewed all immunostained slides. RESULTS: Positive results for Her-2/neu and p53 were found in 44.5% and 34% of the patients, respectively. Positivity for Her-2/neu was significantly associated with increased risk of relapse and death. No correlation was found between p53 mutations and relapse-free survival (RFS) or overall survival (OS). Multivariate analyses included Her-2/neu overexpression and the following variables previously identified as independent predictors of outcome in this population: tumor size, nodal ratio (number of involved nodes/number of dissected nodes), and hormone receptor status. All four variables had independent value. CONCLUSION: Her-2/neu overexpression is an independent negative predictor of RFS and OS in HRPBC treated with HDCT. Its inclusion in our previously described predictive model increases the predictive capacity of this model for the low-risk subgroup. In contrast, p53 mutations lack predictive value in this setting.

Breast cancer-specific mRNA transcripts presence in peripheral blood after adjuvant chemotherapy predicts poor survival among high-risk breast cancer patients treated with high-dose chemotherapy with peripheral blood stem cell support.

PURPOSE: To study the prognostic significance of the presence of breast cancer-specific mRNA transcripts in peripheral blood (PB), defined by serial analysis of gene expression, in high-risk breast cancer (HRBC) patients undergoing high-dose chemotherapy after receiving adjuvant chemotherapy. METHODS: From 1994 to 2000, 84 HRBC patients (median age, 44 years; > 10 nodes; 74%) received adjuvant chemotherapy (fluorouracil, epirubicin, and cyclophosphamide for six cycles [83%] or doxorubicin and cyclophosphamide followed by paclitaxel) before undergoing one course of cyclophosphamide plus thiotepa plus carboplatin (STAMP V). Radiotherapy or hormone therapy was administered whenever indicated. Aliquots of apheresis-mononuclear blood cells were frozen from each patient. mRNA was isolated using an automatic nucleic acid extractor based on the magnetic beads technology; reverse transcription was performed using random hexamers. Cytokeratin 19, HER-2, P1B, PS2, and EGP2 transcripts were quantified to B-glucuronidase by real-time polymerase chain reaction (RT-PCR) using a linear DNA probe marked with a quencher and reporter fluorophores used in RT-PCR. Presence of PB micrometastases, estrogen receptor and progesterone receptor status, tumor size, age, tumor grade, number of nodes affected, and treatment with paclitaxel were included in the statistical analysis. RESULTS: Median follow-up was 68.3 months (range, 6 months to 103 months). Forty-seven relapses (56%) and 35 deaths (41.7%) were registered. Both tumor size and presence of micrometastases reached statistical significance according to the Cox multivariate model. Relapse hazard ratio (HR) for those patients with PB micrometastases was 269% (P = .006); death HR, 300% (P = .011). Time relapse was 53 months longer for patients without micrometastases: 31.3 v 84.2 months (P = .021). CONCLUSION: PB micrometastases presence after adjuvant chemotherapy predicts both relapse and death more powerful than classical factors in HRBC patients undergoing high-dose chemotherapy. Micrometastases search using a gene panel appears to be a more accurate procedure than classical approaches involving only one or two genes.

Illness-specific and general perceptions of social relationships in adjustment to rheumatoid arthritis: the role of interpersonal expectations.

BACKGROUND: Adjustment to rheumatoid arthritis (RA) may be made more difficult when patients are unable to meet the expectations of family and friends about how well they are coping. PURPOSE: This study investigated the influence of illness-specific interpersonal expectations and general indices of social interactions on depressive symptoms among 39 women with RA (M age = 46.9 years; M disease duration = 11.2 years). METHODS: Female patients with RA and their spouses were recruited from an outpatient rheumatology clinic at an urban university hospital. Participants completed questionnaires at home and returned them to the research staff in prepaid, stamped envelopes. RESULTS: Results showed a significant correlation between spousal expectations and patients' perceived inability to meet them. Further, hierarchical regression analyses indicated that even when controlling for disease severity and traditional measures of social interactions (e.g., social support, perceived criticism, and general quality of the dyadic relationship), patient's perceived inability to meet spousal expectations contributed unique variance in depressive symptoms. CONCLUSIONS: These results suggest that adjustment to RA is not due entirely to the general features of social relationships, but additionally reflect specific aspects of the chronic illness milieu where spousal expectations and the patient's perceived inability to meet them are also related to adjustment.

Forced collectionism after orbitofrontal damage.

A collector is a person who collects things on purpose, either as a hobby or business, or for personal satisfaction, e.g., stamp, coin, or art collector. In such instances, the act of collecting things represents voluntary, controlled, goal-directed, selective searching. Pathologic patterns of collecting have been observed following brain damage, particularly frontal lobe damage, ranging from a tendency to grasp (prehension behavior) to an irrepressible need to seize surrounding objects and store them (hoarding behavior). These adnormal behaviors express an excessive adherence to environmental stimuli but in no way express a planned process directed toward specific items. In this article, we describe an unusual pattern of pathologic collecting behavior due to frontal lobe damage: involuntary irrepressible collecting that is goal-directed and selective. The authors report a patient who collected specifically household electrical appliances following a bilateral damage of orbito- and polar-prefrontal cortex. The patient had involuntary irrepressible collecting that was goal-directed and selective. This "forced collectionism" is different from that of the usual collectionism encountered in patients with frontal lobe lesions, as the latter is in no way a planned process directed toward specific items.

The medicolegal importance of enhancing timeliness of documentation when using an anesthesia information system and the response to automated feedback in an academic practice.

Documentation should ideally occur in real time immediately after completion of a service. Although electronic records often do not print the time that documentation notes were entered on the medical record, automated anesthesia record keeping systems store an audit trail that time stamps events entered by all anesthesia providers. As more lawyers become aware of this fact and requisition audit trails, prospective charting of necessary documentation may undermine the integrity of an anesthesia care team accused of malpractice, with potentially significant medicolegal consequences. We changed existing documentation practices of a large academic practice via a three-step process. Educational sessions increased the percentage of cases with correct timing of emergence documentation from 25% to 60% over a 2-mo period. Automated email performance feedback further increased correct note timing to 70%. When combined with personal contact by a member of the billing office and email copy notification of the chair, the percentage increased to >99.5%. The behavioral change was seen in all individuals, as 95% of attendings had < or = 2 records/mo with untimely documentation at the end of the study period. Once the habits were ingrained, further input was rarely necessary over the next 9 mo. This suggests physician behavioral change related to work process flow, unlike that related to patient care, is easily sustained.

Domestic food policy in the United States.

In this paper we review the major outlines of domestic food programs, assess their adequacy, and recommend ways to improve the relationship between food programs and hunger relief. In the Food Stamp Program we treat problems of outreach, coverage and the adequacy of benefits, and rationing access through imposition of costs on recipients. For WIC and commodity distribution programs we also discuss problems associated with the fragmentation of authority and dependence on nonprofit distributors.

Sperm plasma membrane breakdown during Drosophila fertilization requires sneaky, an acrosomal membrane protein.

Fertilization typically involves membrane fusion between sperm and eggs. In Drosophila, however, sperm enter eggs with membranes intact. Consequently, sperm plasma membrane breakdown (PMBD) and subsequent events of sperm activation occur in the egg cytoplasm. We previously proposed that mutations in the sneaky (snky) gene result in male sterility due to failure in PMBD. Here we support this proposal by demonstrating persistence of a plasma membrane protein around the head of snky sperm after entry into the egg. We further show that snky is expressed in testes and encodes a predicted integral membrane protein with multiple transmembrane domains, a DC-STAMP-like domain, and a variant RING finger. Using a transgene that expresses an active Snky-Green fluorescent protein fusion (Snky-GFP), we show that the protein is localized to the acrosome, a membrane-bound vesicle located at the apical tip of sperm. Snky-GFP also allowed us to follow the fate of the protein and the acrosome during fertilization. In many animals, the acrosome is a secretory vesicle with exocytosis essential for sperm penetration through the egg coats. Surprisingly, we find that the Drosophila acrosome is a paternally inherited structure. We provide evidence that the acrosome induces changes in sperm plasma membrane, exclusive of exocytosis and through the action of the acrosomal membrane protein Snky. Existence of testis-expressed Snky-like genes in many animals, including humans, suggests conserved protein function. We relate the characteristics of Drosophila Snky, acrosome function and sperm PMBD to membrane fusion events that occur in other systems.

Improving the quality of information on pathology request forms.

BACKGROUND: We have investigated the causes of incomplete pathology request forms received at our clinical chemistry laboratory. Based on a request form audit we found that the data most frequently missing from a pathology request form was the doctor's name, unique identification provider number, or signature. METHODS: We examined the effect of issuing the requesting doctors with self-inking stamps personalized with their name and a unique provider number. RESULTS: The intervention led to an immediate and sustained improvement in compliance, with the proportion of incomplete forms falling from 43% to 2%. In contrast, distribution of a memorandum alone made no significant change to the number of pathology request forms with incomplete data arriving at the laboratory. CONCLUSION: This study describes a simple and low-cost solution to one of the causes of incomplete pathology request forms. It also demonstrates the effectiveness of systems improvement in health care.

The adherence to antiretroviral treatment evaluated from a hospital pharmacy: importance of the protease inhibitors pharmacological class.

The goal of this study was to develop an evaluation method of antiretroviral treatment adherence from a hospital pharmacy and to identify one or more factors that influenced this adherence, such as patient or treatment characteristics. The HIV patients included in this study were based, for the major part, in Saint-André hospital and collected their medication from this hospital pharmacy. They were all delivered a renewable prescription that should have comprised two successive delivery stamps. A total of 186 patients was included. For the adherence analysis, the delay between two successive deliveries was measured. We have specified three different categories of patients: adherent, non-adherent and intermediate, according to a definition of adherence accepted by many authors. We have demonstrated that the only antiretroviral therapeutic class associated with poor adherence was the protease inhibitors, in particular nelfinavir, which requires food to be taken at the time of administration. This can pose difficulties for those patients who lunch at their workplace and consequently affect adherence. This study allowed us to demonstrate that a less subjective adherence evaluation can be easily carried out from a hospital pharmacy.

Factors relating to patients' reports about hospital care for coronary heart disease in England.

OBJECTIVES: All health care providers in England are required to conduct surveys of their patients' experience of health care. Data from such surveys contribute to the 'star rating' performance indicators. However, there are concerns that these subjective measures may be influenced more by characteristics of patients than by true variations in the quality of care. The purpose of this paper is threefold: to determine the relationship between demographic characteristics and an index measure of patients' reported experience; to explore the extent to which patients' experiences may be accounted for by the particular National Health Service (NHS) trust they attended; and to assess how meaningful a summary index is in terms of its ability to discriminate between providers. METHODS: Data from patients in the National Survey of National Health Service Patients treated for coronary heart disease in 194 NHS trusts. Patients were sent questionnaires after discharge, with a covering letter and a prepaid stamped addressed envelope. Up to two reminders were sent to non-responders. Multi-level linear regression models were used to estimate the extent to which patients' experiences differed between trusts and the association of demographic variables with the summary index. RESULTS: In total, 116,872 patients were sent questionnaires, but 3399 proved to be ineligible for the survey. Responses were gained from 84,310 (74.3% of eligible respondents). Age and sex were most strongly associated with reported patients' experiences. However, the actual impact of age and sex on patients' experience is small, accounting for less than 3% of the variance. The proportion of the variance that was accounted for by the hospital trust in which patients were treated was only 5%. CONCLUSIONS: Demographic characteristics do not appear to account for differences between hospital trusts in patients' experience of health care. However, there is considerable variation in patients' experience within each provider. This would suggest that summary indices of patients' experience should not be used to rank providers, although detailed information from patient surveys have a useful role in determining priorities for quality improvement within individual hospitals and for assessing changes over time.

Lectin-binding characteristics and capacitation of canine epididymal spermatozoa.

Cross sections of the testes and the caput, corpus and cauda epididymides removed from 12 dogs were stamped on glass slides, and the sperm on the slides were stained with 6 different FITC-lectins (Con A, DBA, PNA, PSA, SBA, and WGA) to examine the characteristics of the surface glycoproteins (GPs) on canine epididymal sperm. The corpus epididymal sperm were washed three times by centrifugation, and their lectin-binding characteristics were investigated. The washed sperm from the corpus and cauda epididymides were incubated for 24 hr, and the fertilizing capacity of the sperm was evaluated by calculating the percentages of actively motile sperm (%MO), hyperactivated sperm (%HA), and acrosome-reacted sperm (%AR), and the number of canine zona-pellucida (ZP)-binding sperm. The testicular sperm did not stain with SBA lectin, but the SBA lectin fluorescence was observed on the surface of the entire heads of the caput epididymal sperm. Although all of the entire heads or acrosomal regions of the corpus epididymal sperm stained with all 6 FITC-lectins, the heads and acrosomal regions of the cauda epididymal sperm did not stain with DBA or SBA lectins. Washing the sperm from the corpus epididymis resulted in loss of the fluorescence of the FITC-DBA and -SBA lectins. The mean %MO, %HA, %AR, and ZP-binding number of the cauda epididymal sperm after 24 hr of incubation were higher than the values for the corpus epididymal sperm. All of the mean values for the washed sperm from the corpus and cauda epididymides were higher than the values for the unwashed sperm from the corpus and cauda, and with the exception of %AR, the values from the washed sperm from the corpus epididymis were significantly higher (P<0.05, 0.01). The results indicate that DBA- and SBA-lectin-binding GPs on the surface of canine epididymal sperm are associated with the fertilizing capacity and may be decapacitation factors.

Disappearance of the PHA-E lectin binding site on the surface of ejaculated sperm and sperm capacitation in the dog.

Ejaculated semen and cross sections of the cauda epididymides collected from 3 normal dogs were smeared or stamped on glass slides, and the sperm on the slides were stained with 7 different FITC-lectins (Con A, DBA, GS-1, PHA-E, PSA, UEA-1, WGA) to examine the relation between sperm-binding glycoprotein derived from the canine prostate and sperm capacitation. The only lectin that stained the ejaculated sperm but not the cauda epididymal sperm was PHA-E. The sperm ejaculated by 5 other dogs were incubated for 4 hr in fluid flushed from the uterine horns or oviducts of estrous bitches, and then the percentages of actively motile sperm and hyperactivated sperm (HA-sperm) were determined. The percentages of PHA-E-labeled sperm and sperm labeled with fluoresceinated Ca indicator to assess the influx of Ca into the sperm were also evaluated. The mean percentages of actively motile sperm, HA-sperm, and Ca-labeled sperm after 4 hr of incubation in the uterine flush fluid and oviductal flush fluid were significantly higher than in control medium (P<0.05, 0.01), but the mean percentages of PHA-E-labeled sperm were lower (both P<0.01). The percentages of PHA-E-unlabeled sperm correlated with the percentages of both HA-sperm and Ca-labeled sperm (r(2)=0.787 and 0.812, respectively). The results indicate that loss of the glycoprotein secreted by the canine prostate on the sperm surface induces the influx of Ca into the sperm, and then hyperactivation of the sperm.

Formation of detached tail and coiled tail of sperm in a beagle dog.

The right testis and epididymis were excised from a Beagle dog that ejaculated high percentages of sperm with detached tails and with coiled tails. Cross sections of the organs were stamped on glass slides and histological examination of the organs was performed to find the portion where sperm with the abnormal tails appear. Many sperm with tails whose axoneme was exposed near the neck region were observed in the testis and they decreased in order from the caput, to the corpus, and the cauda epididymis. Sperm with detached tails and sperm with coiled tails gradually increased in the epididymis. These findings indicate that the tails of sperm with an exposed axoneme detached in the epididymis.

Hunger: a hospital survey.

Patients at a New York City municipal hospital were surveyed in 1985 and 1989 to ascertain the extent of hunger and its possible correlates. Twenty-two percent (22%) of the 382 subjects in 1985 and 23% of the 332 subjects in 1989 experienced hunger. Hunger was related significantly to homelessness, social isolation and the physical inability to buy and/or prepare food. Between 1985 and 1989, there was a large increase in the use of institutional resources for food; a decline in reliance on Food Stamps; and an increase in household density. Inpatients were found to be poorer than outpatients, and to rely more heavily upon soup kitchens. Practice, policy and research implications are noted.
