[source] ,Iron Fists in Iron Gloves': The Political Economy of US Terrorocracy Promotion in Colombia1BRITISH JOURNAL OF POLITICS & INTERNATIONAL RELATIONS, Issue 3 2006Doug Stokes Most analysts of US post-cold war policy in Colombia argue that the US has switched from targeting Communist guerrillas to a war on drugs and a new war on terror. Contrary to these claims this article shows that the US continues to back Colombian counter-insurgency efforts which essentially amount to a strategy of state terrorism under a democratic façade (terrorocracy). Moreover, this policy continues to be pursued because the US has long employed counter-insurgency warfare to stabilise social formations conducive to US political and economic interests. In short, counter-insurgency warfare is the military strategy par excellence for the policing and reproduction of global capitalism via localised proxy forces throughout the third world. In Colombia this strategy continues to have profound consequences for human rights, social justice and democracy. [source] 1-Hz repetitive TMS over ipsilateral motor cortex influences the performance of sequential finger movements of different complexityEUROPEAN JOURNAL OF NEUROSCIENCE, Issue 5 2008Laura Avanzino Abstract To elucidate the role of ipsilateral motor cortex (M1) in the control of unilateral finger movements (UFMs) in humans we used a conditioning protocol of 1-Hz repetitive transcranial magnetic stimulation (1-Hz rTMS) over M1 in 11 right-handed healthy subjects. We analysed the effects of conditioning rTMS on UFMs of different complexity (simple vs sequential finger movements), and performed with a different modality (internally vs externally paced movements). UFMs were monitored with a sensor-engineered glove, and a quantitative evaluation of the following parameters was performed: touch duration (TD); inter-tapping interval (ITI); timing error (TE); and number of errors (NE). 1-Hz rTMS over ipsilateral M1 was able to affect the performance of a sequence of finger opposition movements in a metronome-paced condition, significantly increasing TD and reducing ITI without TE changes. The effects on motor behaviour had a different magnitude as a function of the sequence complexity. Further, we found a different effect of the ipsilateral 1-Hz rTMS on externally paced movements with respect to an internally paced condition. All these findings indicate that ipsilateral M1 plays an important role in the execution of sequential UFMs. Interestingly, NE did not change in any experimental condition, suggesting that ipsilateral M1 influences only the temporal and not the spatial accuracy of UFMs. Finally, the duration (up to 30 min) of 1-Hz rTMS effects on ipsilateral M1 can indicate its direct action on the mechanisms of cortical plasticity, suggesting that rTMS can be used to modulate the communication between the two hemispheres in rehabilitative protocols. [source] Is Agency Skin Deep?INFANCY, Issue 3 2004Surface Attributes Influence Infants' Sensitivity to Goal-Directed Action Three studies investigated the role of surface attributes in infants' identification of agents, using a habituation paradigm designed to tap infants' interpretation of grasping as goal directed (Woodward, 1998). When they viewed a bare human hand grasping objects, 7- and 12-month-old infants focused on the relation between the hand and its goal. When the surface properties of the hand were obscured by a glove, however, neither 7- nor 12-month-old infants represented its actions as goal directed (Study 1). Next, infants were shown that the gloved hands were part of a person either prior to (Study 2) or during (Study 3) the habituation procedure. Infants who actively monitored the gloved person in Study 2 and older infants in Study 3 interpreted the gloved reaches as goal directed. Thus, varying the extent to which an entity is identifiable as a person impacts infants' interpretation of the entity as an agent.

Walker MD Assistant in Medicine No abstract is available for this article. [source] The importance of nasal provocation test in the diagnosis of natural rubber latex allergyALLERGY, Issue 6 2009M. Ünsel Background:, Most studies regarding natural rubber latex (NRL) allergy have concentrated on the prevalance using skin prick test (SPT) and specific IgE assay. The objective of this study is to examine the target organ (skin, nasal mucosa) responses in patients with positive SPT to NRL using the nasal provacation test (NPT) and glove use test (GUT). Methods:, Four thousand four hundred and twenty patients presented to our polyclinic between July 2003 and January 2007 were evaluated. One thousand six hundred and ninety-nine patients had positive SPT to one or more allergens (NRL and other inhaler allergens). Twenty-nine patients with positive SPT to NRL comprised the NRL sensitive group (group 1). Thirty-five randomized patients with positive SPT to an inhaler allergen other than NRL and negative NRL-specific IgE comprised atopic control group (group 2). Thirty healthy individuals who had no allergic diseases and had negative SPT and NRL-specific IgE comprised the healthy control group (group 3). Results:, The lowest NRL allergen concentration leading to NPT positiveness was 0.05 ,g/mL. NPT was negative in groups 2 and 3. NPT was found to have a sensitivity of 96%, specificity of 100%, negative predictive value of 98% and positive predictive value of 100%. GUT was found to have a sensitivity of 81%, specificity of 90%, negative predictive value of 75% and positive predictive value of 93%. Conclusions:, Nasal provocation test was successfully used for the first time in the diagnosis of NRL allergy. NPT is a more sensitive method as compared to GUT. [source] The ,Thailand Controversy' RevisitedTHE AUSTRALIAN JOURNAL OF ANTHROPOLOGY, Issue 2 2002Peter Hinton The so-called ,Thailand controversy' divided the anthropological communities of Australia and the US in the early 1970s. In the heat of opposition to the Vietnam War, allegations were made that some anthropologists and institutions, particularly the Tribal Research Centre in Thailand, had worked hand in glove with the military/intelligence establishment and contrary to the interests of the minority peoples who lived in the hills of north Thailand, who were the subjects of research. The author was one of those so accused and the paper presents his view of the episode. It traces the genesis of the Tribal Research Centre, the publication of an inflammatory article in the US, and the subsequent escalation of the controversy there. It then details its impact on the Australian anthropological community, with particular reference to the Sydney University Department. Finally, it describes the climax of the controversy in the Australian Association of Social Anthropologists, and the American Anthropological Association. In conclusion, it argues that the confused intensity of the affair was a product of a mix of political passions, ethical considerations, and different views about the role of academics in society. [source] Comparison of open and closed staff-assisted glove donning on the nature of surgical glove cuff contaminationANZ JOURNAL OF SURGERY, Issue 3 2010Christopher Jones Abstract Background:, We have observed that surgical glove cuffs commonly fold over during an operation, exposing the inside of the glove cuff to the sterile field and wound, a potential source of contamination if the inside of the glove cuff has been in contact with the fingers during glove donning. We hypothesize that open staff-assisted gloving results in more inside-glove cuff contamination than a closed staff-assisted technique. Method:, We performed a blinded, randomized study comparing open and closed staff-assisted glove donning. Two surgeons were gloved 20 times after covering their fingers and hands with GlitterBug(TM) powder. The gloves were turned inside out and the distance of GlitterBug(TM) powder from the free edge of the cuff was measured. Results:, Staff-assisted open glove donning was associated with significantly more glove cuff contamination than closed staff-assisted glove donning (P= 0.001). Conclusion:, Given glove cuff ,turn down' intra-operatively, we strongly recommend closed staff-assisted gloving. [source] Nothing to sneeze at!ANZ JOURNAL OF SURGERY, Issue 12 2009A study into intra-operative contamination Abstract Purpose:, We performed a prospective study of sneezes from orthopaedic registrars to assess the potential for intra-operative contamination from a masked surgeon, and to determine if head position can alter the potential for contamination. Type of Study:, Prospective controlled trial. Methods:, Four orthopaedic registrars from the Gold Coast Hospital each inhaled pepper to precipitate a sneeze. Cultures were taken with and without standard Smith & NephewÔ surgical masks, in positions directly in front and to the sides of a masked registrar. The process was repeated three times for each registrar. A control plate was left exposed to the atmosphere. A control plate and sneeze plate was cultured on blood agar. Three masks were subsequently swabbed to exclude contamination from the masks. Results:, 2/24 (8.33%) of the side with mask cultures returned significant bacterial growths. Also, 1/12 (8.33%) of the front with mask cultures returned significant growths. In addition, 9/12 (75%) of the direct sneezes resulted in significant bacterial counts. The control plate failed to return any growth. Subsequent culture of the exterior of three surgical masks failed to yield significant growth. There was a statistically significant odds ratio of 0.03 comparing the front and side group with the unmasked direct group. There was no statistically significant difference comparing front and side sneeze growth. Conclusions:, While the use of surgical face masks significantly reduces bacterial counts following a sneeze, it fails to eliminate the potential for surgical field contamination completely. The fact that significant bacterial counts can be returned from direct culture through a mask and to the sides of a mask suggests that head position is irrelevant and contamination is possible in any direction. It is, therefore, suggested that, if possible, a sneezing surgeon distances himself/herself as much as possible from the sterile field. We also recommend following a sneeze; surgeons should re-gown and glove, given the risk of contamination of the sterile field. Level of evidence:, Level II. [source] Glove perforations during open surgery for gynaecological malignanciesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 8 2008AP Manjunath Objective, To audit glove perforations at laparotomies for gynaecological cancers. Setting, Gynaecological oncology unit, cancer centre, London. Design, Prospective audit. Sample, Twenty-nine laparotomies for gynaecological cancers over 3 months. Methods, Gloves used during laparotomies for gynaecological cancer were tested for perforations by the air inflation and water immersion technique. Parameters recorded were: type of procedure, localisation of perforation, type of gloves, seniority of surgeon, operation time and awareness of perforations. Main outcome measure, Glove perforation rate. Results, Perforations were found in gloves from 27/29 (93%) laparotomies. The perforation rate was 61/462 (13%) per glove. The perforation rate was three times higher when the duration of surgery was more than 5 hours. The perforation rate was 63% for primary surgeons, 54.5% for first assistant, 4.7% for second assistant and 40.5% for scrub nurses. Clinical fellows were at highest risk of injury (94%). Two-thirds of perforations were on the index finger or thumb. The glove on the nondominant hand had perforations in 54% of cases. In 50% of cases, the participants were not aware of the perforations. There were less inner glove perforations in double gloves compared with single gloves (5/139 versus 26/154; P = 0.0004, OR = 5.4, 95% CI 1.9,16.7). The indicator glove system failed to identify holes in 44% of cases. Conclusions, Glove perforations were found in most (93%) laparotomies for gynaecological malignancies. They are most common among clinical fellows, are often unnoticed and often not detected by the indicator glove system. [source] Low-cost laparoscopic cholecystectomyBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 12 2002A. Champault Background: Hospital managers are continually trying to decrease the cost of patient care. The aim of this prospective study was to propose changes that would decrease the operating room costs of laparoscopic cholecystectomy without affecting clinical results. Methods: The study included 112 consecutive patients who underwent an elective cholecystectomy between January 1997 and December 2000. The procedure was changed in eight ways: the American position, open laparoscopy, reusable trocars, reusable instruments, bipolar coagulation of the cystic artery, intracorporeal ligature of the cystic duct, no use of suction lavage apparatus, and use of a surgical glove as a bag to extract the gallbladder. Complete compliance with the procedure, whether any abnormal operative events or complications occurred, the duration of hospitalization, and the material and labour costs of the procedure were recorded. Results: There were no abnormal operative events. Only two patients suffered from postoperative complications. The mean duration of hospitalization was 55·8 h. Fifteen patients (13·4 per cent) were not hospitalized overnight. The operating costs fell from 560 euros before the study to 330 euros in 2000. Conclusion: By applying simple measures, it is possible to decrease the operating room cost of laparoscopic cholecystectomy whilst maintaining good results. Such measures should be applied to other laparoscopic procedures. © 2002 British Journal of Surgery Society Ltd [source] Real-time locomotion control by sensing glovesCOMPUTER ANIMATION AND VIRTUAL WORLDS (PREV: JNL OF VISUALISATION & COMPUTER ANIMATION), Issue 5 2006Taku Komura Abstract Sensing gloves are often used as an input device for virtual 3D games. We propose a new method to control characters such as humans or animals in real-time by using sensing gloves. Based on existing motion data of the body, a new method to map the hand motion of the user to the locomotion of 3D characters in real-time is proposed. The method was applied to control locomotion of characters such as humans or dogs. Various motions such as trotting, running, hopping, and turning could be produced. As the computational cost needed for our method is low, the response of the system is short enough to satisfy the real-time requirements that are essential to be used for games. Using our method, users can directly control their characters intuitively and precisely than previous controlling devices such as mouse, keyboards or joysticks.

[source] FC03.1 Experience from joint occupational health/dermatology clinicsCONTACT DERMATITIS, Issue 3 2004Yat Wing Wong Background:, A monthly consultant led occupational health/dermatology clinic was started in 1999 providing rapid access to staff with suspected occupational skin disease including natural rubber latex (NRL) allergy and teaching for the occupational health staff. Objectives:, To evaluate the characteristics and outcome of staff attending this clinic and to assess patient satisfaction. Methods:, A retrospective case note survey was performed from staff attending the clinic from 1999 to 2002. A questionnaire was sent to them >3 months following consultation. Results:, A total of 116 patients were identified (12 male, 104 female), and 85 (73%) were nurses. 77 (66%) patients were referred with hand eczema (HE). Of the 45 patients referred with adverse reactions or exacerbation of hand dermatitis following the use of latex gloves, only 4 had positive prick tests and were considered to have NRL allergy. Patients with significant HE or occupational exacerbation of HE were referred for patch testing (n = 36). Of the remainder, most could be discharged after a single visit. 49/95 (52%) questionnaires were returned, 34/45 (76%) patients found the consultation useful. As a separate study, the data recorded within the patch test clinic looking at health care workers (HCW) referred both from this clinic and from other sources was analysed. This showed relevant positive patch tests in 16/49 (33%) patients. In 55/99 (56%), an occupational cause was likely. Conclusion:, Occupational skin disease in HCW is common, attendance at the clinic was beneficial and a single visit was sufficient in most cases. [source] FS13.3 Development of risk reduction strategies for preventing dermatitisCONTACT DERMATITIS, Issue 3 2004Terry Brown Introduction:, A recent survey of the UK printing industry found a prevalence of 11% of occupational contact dermatitis (OCD), much higher than previously identified. Objective:, This pilot study aimed to evaluate risk reduction strategies derived from recommendations of a literature review of preventive intervention studies and a series of focus groups of printers and observations of printers undertaking their normal duties. Methods:, Four interventions were evaluated: (1) Provision of gloves of the correct size/type, plus use of an after-work skin cream; (2) Provision of information; (3) Provision of skin checks; (4) Development of best practice skin care policy. Each intervention was evaluated in two companies over a three-month period, at the end of which printers and managers were interviewed as to the effectiveness and acceptability of each intervention. Results:, Although this pilot study was short, all interventions were acceptable to some extent. The prevalence of frank dermatitis fell over the study period, particularly in intervention (3). Intervention (1) achieved an improvement of awareness in both management and workforce and an increase in the use of both gloves and cream. Intervention (2) highlighted problems of dissemination and the need for relevant information in an appropriate format. However. no single intervention was completely effective. Conclusions:, This qualitative research approach forms an essential first stage to improving understanding of ways in which OCD may be reduced among workers in the printing industry, and points towards the need for further testing of preventive strategies in larger-scale intervention trials, in printing and other industries. [source] FS13.5 Occupational contact dermatitis: printer worker's viewpointsCONTACT DERMATITIS, Issue 3 2004Terry Brown Introduction:, Occupational contact dermatitis (OCD) is very common in the printing industry due to contact with chemicals, paper, and wet work. It can be avoided by adequate protective measures, but the effectiveness of intervention depends heavily on the employer's and employee's awareness of this health risk. Objectives:, The study aimed to collect information on the knowledge, attitudes and beliefs of print workers about the risk of OCD and methods of prevention. Methods:, A series of focus groups were held with print workers, health and safety officers and managers to discuss their awareness of dermal risk factors, risk behaviour at work, attitudes to health and safety and options on possible preventive measures. A number of companies were also visited to observe, overtly and covertly, the normal work practices. Results:, OCD was not perceived to be either a major problem or a health and safety priority. There was general agreement about the processes and work practices that could cause skin problems. However, work practices varied considerably and did not always reflect this awareness. There was general concern about the type and availability of personal protective equipment, especially gloves and after-work skin cream. The provision of an occupational health service was generally felt to be inadequate, and no company had a policy in place that specifically addressed skin care. Conclusions:, These findings highlight the urgency to intensify health and safety education on skin care within the printing industry. Recommendations were developed for the evaluation of a series of risk reduction strategies. [source] P03 Type-I and -IV hypersensitivity to platinum saltsCONTACT DERMATITIS, Issue 3 2004Willeke Kamphof A 28-year-old female analytical chemist visited our patch test clinic with initially complaints of severe hand dermatitis. Later on she developed rhinitis, bronchial asthma and tightness of the chest. The complaints seemed work related: her condition improved during holidays and on sick leaves. She worked in a laboratory with several platinum salts and used different kinds of gloves (latex, nitril, etc.). Methods:, Patch tests were performed with the European Standard series and prick tests with common inhalant allergens. Patch-, prick- and open patch tests were carried out with various aqueous dilutions of platinum chloride (PtCl2). Results:, Patch tests with 0.01,2% PtCl2 were positive on day 2, 3 and 6, and at 0.001% a follicular reaction was found. The prick-test was already positive at the lowest concentration tested (0.001%). The open patch test, carried out retro-auricular, showed a positive reaction at 1 and 2% PtCl2 after 20 min. Controls in healthy volunteers (n = 5) were all negative. Discussion:, It is well known that platinum salts can cause type-I hypersensitivity reactions like allergic rhinitis, conjunctivitis, bronchial asthma and urticaria, also referred to as platinosis. Contact dermatitis to platinum salts, however, is very rare. In our patch test clinic, 78 patients were tested between 1987 and 2001 with PtCl2 2%. Only 2 women showed a positive patch test for PtCl2. The patient presented here, stopped working with platinum salts and recovered from all complaints. We interpret our case as occupational type-I and type-IV hypersensitivity to platinum salts with mucosal and dermal manifestations. [source] The use of protective gloves and the prevalence of hand eczema, skin complaints and allergy to natural rubber latex among dental personnel in the county of Uppsala, SwedenCONTACT DERMATITIS, Issue 1 2000Magnus Lindberg During the past decade, there has been an increasing problem with acrylate allergy and natural rubber latex (NRL) allergy among dental personnel. The aim of the present study was to evaluate the prevalence of these problems among dentists, dental nurses and dental hygienists in Uppsala county, Sweden. The study was based on a self-administered questionnaire sent to 690 persons with 527 responders (76%). The most common skin problem was dry skin, fissures and/or itching on the hands. Of the 72 persons (13.6%) reporting to have suffered from hand eczema during the past 12 months, 41 were patch tested with the TRUE Test standard series and the Swedish dental screening series. In the patch tested group, 9.8% reacted to 1 or more of the acrylates. In addition, 389 persons were tested for NRL allergy with the Pharmacia Upjohn CAP-RAST test, and of these, we found 7.2% to be positive. The prevalence of self-reported hand eczema and the number of positive CAP-RAST tests differed between the 3 occupations, with higher figures for the dentists. There was also a correlation between atopic eczema and hand eczema. Of those reporting skin symptoms, 67.7% connected them to the place of work and 28.8% related them to the use of gloves. [source] FASHIONS AND FUNDAMENTALISMS IN FIN-DE-SIÈCLE YEMEN: Chador Barbie and Islamic SocksCULTURAL ANTHROPOLOGY, Issue 2 2007ANNE MENELEY This article examines the complex relationships between changing forms of commodity production and consumption and changing styles of religiosity in Zabid, the Republic of Yemen. I examine a couple of prominent logics of veiling in Fin-de-Siècle Yemen: Some reformist women add "Islamic socks" and gloves to their already fully modest garb, while other women don chadors that decorate these garments with embroidery, making them into items of fashionable consumption and adornment. Other commodities, like a Chador Barbie that I found in Yemen's suq, are used to think through changing practices of consumption, adornment, and women's sociability in Zabid. [source] Sterile Versus Nonsterile Gloves During Mohs Micrographic Surgery: Infection Rate is not AffectedDERMATOLOGIC SURGERY, Issue 2 2006BRANDON M. RHINEHART MC BACKGROUND: Mohs micrographic surgery (MMS) is an outpatient procedure, which has become the treatment of choice for certain cutaneous malignancies. Although the major steps in this procedure are relatively standardized, one difference involves the use of sterile or nonsterile, clean gloves during the tumor removal phase. OBJECTIVE: This retrospective, chart review study was performed to evaluate whether infection rates are affected by the use of sterile versus nonsterile gloves in the tumor extirpation phase of MMS. METHODS: This study evaluated the surgical records of 1,810 consecutive Mohs patients, of which 1,239 Mohs patients (1,400 Mohs procedures) met inclusion criteria. Age, sex, tumor diagnosis, anatomic location, number of Mohs stages, area of defect, closure type, cartilage exposure, and sterile versus nonsterile glove use were recorded and evaluated. RESULTS: Twenty-five infections were identified. Statistically significant infection rates were discovered for patients with cartilage fenestration with secondary healing and malignant melanoma diagnosis only. There was no statistical difference in infection rates with all other measured variables to include the use of sterile or clean, nonsterile gloves. CONCLUSION: Our study lends support that clean, nonsterile gloves are safe and effective for use in the tumor extirpation phase of MMS, at a significant cost savings. [source] Latex allergy: diagnosis and managementDERMATOLOGIC THERAPY, Issue 4 2004James S. Taylor ABSTRACT:, Latex allergy is an IgE-mediated immediate hypersensitivity response to natural rubber latex (NRL) protein with a variety of clinical signs ranging from contact urticaria, angioedema, asthma, and anaphylaxis. Major allergens include dipped latex products such as gloves and balloons. In highest risk for NRL allergy are patients with spina bifida, but health care workers and others who wear latex gloves are also at risk. NRL allergic patients may also react to fruits/foods, especially banana, kiwi, and avocado. Diagnosis is made by a positive latex RAST and/or skin prick test or challenge test to NRL. Allergen avoidance and substitution and the use of latex-safe devices including synthetic gloves (vinyl, synthetic polyisoprene, neoprene, nitrile, block polymers, or polyurethane) are essential for the affected patient. Accommodation in the workplace may include the use of powder-free, low-allergen NRL gloves or synthetic gloves. These preventive measures have significantly reduced the prevalence of reported reactions to NRL. Hyposensitization is not yet feasible. [source] Emergency department personal protective equipment requirements following out-of-hospital chemical biological or radiological events in AustralasiaEMERGENCY MEDICINE AUSTRALASIA, Issue 2 2007Guy W Sansom Abstract Recent events have led to a revision in ED equipment, preparedness and training for disasters. However, clinicians must still decide when, and what level of personal protection is required when a toxic threat exists. If possible, clear, simple and achievable protocols are required in such situations. Following an off-site Australasian chemical biological or radiological incident, current evidence indicates that the initial receiving ED staff will be adequately protected from all known chemical biological and radiological inhalational threats by wearing a properly fitted P2 (N95) mask, or its equivalent. Protection from serious contact injury is offered by wearing double gloves, disposable fluid-repellent coveralls or gown, eye protection, surgical mask, and ideally, a cap and shoe covers; in conjunction with universal precautions and procedures. [source] Persistent inhibition of human natural killer cell function by ziram and pentachlorophenolENVIRONMENTAL TOXICOLOGY, Issue 4 2005Thyneice R. Taylor Abstract Ziram is a currently used agricultural fungicide. It is also used as an additive in the production of latex gloves. Because of these uses, there is a potential for human exposure to this compound. Pentachlorophenol (PCP) has been used as an insecticide, fungicide, disinfectant, and ingredient in antifouling paints. Currently, it is used as a wood preservative for power-line poles and fence posts. Measurable levels of PCP have been detected in human blood and urine. In previous studies we demonstrated that both these compounds could cause very significant inhibition of the tumor-killing function of human natural killer (NK) cells. NK lymphocytes play a central role in immune defense against viral infection and the formation of primary tumors. So interference with their function could increase the risk of tumor development. In the present study we examined the effects of exposure to ziram or PCP of brief duration (1 h) on the ability of NK cells to destroy tumor cells. NK cells were exposed to either ziram (5,0.5 ,M) or PCP (10,5 ,M) for 1 h followed by 0 h, 24 h, 48 h, or 6 days in compound-free media and then were tested for the ability to lyse as well as to bind tumor cells. A 1-h exposure to as little as 2.5 ,M ziram decreased the ability of NK cells to lyse target tumor cells, which persisted up to 6 days following exposure. The loss of lytic function for from 24 h to 6 days following exposure was accompanied by a comparable loss of NK capacity to bind tumor cells. Exposure to 10 ,M PCP for 1 h caused a progressive loss (greater than 80%) of lytic function within 6 days of exposure. In contrast to ziram, PCP exposure caused no accompanying loss of binding function. © 2005 Wiley Periodicals, Inc. Environ Toxicol 20: 418,424, 2005. [source] A cost-effective simulation curriculum for preclinical endodonticsEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 1 2004Roberta Pileggi A challenge in contemporary dental education is to achieve a smooth transition from preclinical teaching environments to patient-care clinics in a cost-effective manner. The preclinical endodontic courses at The University of Texas, Dental Branch at Houston provide a unique learning environment that enables the student to perform endodontic treatment on extracted teeth in a typodont, and be involved in diagnosis and treatment-planning discussions. The specially designed stone typodont used has built-in radiographic capability, and is mounted at each chair in the clinic. During each preclinical session, students are assigned clinical cubicles and proper aseptic protocol is followed. Students are required to wear gloves, masks and eyewear, and place a rubber dam during treatment. Written self-assessment evaluations based upon prescribed criteria are utilised; feedback is given by faculty composed of both full-time endodontists and graduate students who periodically rotate and are calibrated on a regular basis. In the lecture phase, clinical case scenarios are presented to reinforce concepts of diagnosis and emergency care and to help integrate endodontics with other disciplines; a Socratic-like teaching style is established by the faculty facilitator to create an environment for developing critical-thinking and problem-solving skills. The overall feedback from graduating students has been very positive. Advantages of this format are an easier transition to patient management, a more keen interest in specialsation and a perceived increase in levels of confidence. [source] Effective interventions with chlorhexidine gluconate (CHG) to decrease hemodialysis (HD) tunneled catheter-related infectionsHEMODIALYSIS INTERNATIONAL, Issue 1 2005N. Redman Purpose:,Identify practices to reduce HD catheter access related bacteremias (ARB). Methods:,Data was collected per the CDC Dialysis Surveillance Network protocol. ARB was defined as a patient with a positive blood culture with no apparent source other than the vascular access catheter. ARB's were calculated in events per 100 patient months with 3 cohorts. Cohort 1 was observed for 12 months, Cohort 2 for the subsequent 10 months, and Cohort 3 for the final 10 months. Cohort 1 had weekly transparent dressing changes, cleansing of the skin and 5 minute soaking of the connection lines with 10% povidone-iodine (PI) solution, and HCW use of clean gloves and face shield without a mask. Cohort 2 changes consisted of thrice weekly gauze dressing changes, skin cleansing with ChloraPrep, a 2% CHG/70% isopropyl alcohol applicator, masks on the patients, adding a face mask to the shield, and application of 10% PI ointment to the exit site. Cohort 3 changes included weekly application of BioPatch (BioP), an antimicrobial dressing with CHG, sterile glove use, and replacing the PI line soaks with 4% CHG. Results:,The catheter-associated ARB rate per 100 patient months was 7.9 (17ARB/216 patient months) in Cohort 1, 8.6 (13/151) in Cohort 2, and 4.7 (5/107) in Cohort 3(p = 0.31 compared with Cohorts 1 and 2 combined). During the last 2 months, in Cohort 3, 9 catheter lumen cracks occurred, with one of the patients having a bacteremia. Conclusions:,Addition of CHG line soaks and BioP reduced tunneled catheter infections, although this is not statistically significant. The increased number of catheter lumen cracks raises concern with the use of CHG line soaks. Further investigation with use of CHG line soaks and the BioP for decreasing ARB is needed. [source] AIDS care in Nigeria: Are nurses comfortable performing procedures?INTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 1 2008Adetoyeje Y Oyeyemi PT DHSc GCS Nurses' feeling of comfort during care is important to stay on the job and for their choice of specialty of care. This study aimed to assess nurses' level of comfort in providing care to patients living with AIDS and to determine the sociodemographic variables that influence nurses' comfort. Nurses in four hospitals in Nigeria (n = 277) were surveyed using a questionnaire that elicited information on their demographic characteristics, previous AIDS encounter, and their comfort taking vital signs, casually handling, administering enema and mouth-to-mouth resuscitation, and in recommending exercise and physical therapy to patients living with AIDS. Nigerian nurses were uncomfortable with resuscitation and also showed discomfort not wearing gloves while handling these patients. Being single and male gender influenced nurses' comfort with vital signs and enema administration. Special orientation to include analysis of common tasks and procedures for new nurses assigned to AIDS units is suggested.

This paper reviews the aetiology, epidemiology and dental management of children with latex allergy. The issue of latex allergy has serious consequences for the dental management of children with one or more of the following risk factors: spina bifida, atopy, first surgery before one year of age, history of multiple surgical procedures, congenital urologic abnormalities, gastrointestinal malformations, hydrocephalus internus, ventriculo-peritoneal shunts, spinal cord injuries, and family history of atopy. Management of latex allergy is based upon the diligent avoidance of latex exposure. Universal use of powder-free low-allergen latex gloves is recommended.

Phalen Abstract The aim of this study was to determine whether the acrylonitrile (ACN) content influences the permeation resistance of disposable nitrile rubber (NBR) gloves to aqueous solutions of the pesticide captan. Attenuated total reflectance/Fourier transform infrared (ATR,FTIR) spectrophotometry at 2237 ± 5 cm,1 was used to measure the ACN contents of seven different NBR gloves. The ACN contents of the gloves ranged from 12.7 to 29.9%. Permeation was conducted according to American Society for Testing and Materials (ASTM) Method F 739-99a with a gas chromatography/mass spectrometry analysis of captan in the hexane collection liquid. Significant correlations were found between (1) the ACN content and mass-to-area ratio and the logarithm of the steady-state permeation rate (SSPR; Pearson correlation coefficient = 0.9227, p , 0.05), and (2) the ACN content and mass-to-area ratio and the ASTM normalized breakthrough detection time (NBT) at 0.25 ,g/cm2 (Pearson correlation coefficient = 0.9471, p , 0.05). On average, the NBT increased 120 min for every 5% increase in the ACN content. The average SSPR ranged from 0.002 to 0.40 ,g/cm2/min, a 200-fold difference. Increasing the ACN content resulted in decreased SSPR. ATR,FTIR was useful in determining the NBR polymer ACN content, surface homogeneity, and potential glove chemical resistance. © 2006 Wiley Periodicals, Inc.

Background., Hospitals are places where infective agents abound. Healthcare workers, relatives of patients and students practising in the hospital medium are often exposed to these infective agents. Although the role of the hand and nasal flora of healthcare workers in the development of nosocomial infections has been emphasised by earlier studies, there are a limited number of studies which investigate the hand and nasal flora of nursing students. Design., Descriptive. Methods., This descriptive study involved 66 volunteer nursing students. Two samples of flora from both hands and nose of each student were obtained. The inoculated samples were then evaluated through routine bacteriological study methods. Chi-square and percentage calculations were used in comparisons. Results., None of the students had methicillin-resistant Staphylococcus aureus or methicillin-resistant coagulase-negative Staphylococcus colonisation in the hand samples before clinical practice, 6·1% of the students had methicillin-resistant Staphylococcus aureus and 4·5% had methicillin-resistant coagulase-negative Staphylococcus colonisation after the practice. Although the differences between the rates of contamination with pathogen micro-organisms in the hand and nasal flora of the student nurses before and after clinical practice were not significant, the rate of colonisation after clinical practice was higher. Conclusions., In this study, the rate of colonisation after clinical practice was higher. These findings indicate that students might have been contaminated with bacteria during clinical practice. Relevance to clinical practice., The results of this study have practical importance in clinical practice. The role of the hand and nasal flora of nursing students in the development of nosocomial infections is significant. For this reason, some precautions, such as using gloves and handwashing with special solutions when needed, should be taken to prevent nosocomial infections and protect students against associated risks.

Yoon ABSTRACT:, This study evaluated microbial food safety in school foodservices. Five school foodservices were randomly selected, and samples from water, cooking utensils, tableware, foodservice surroundings, and linen were collected in summer and winter (N= 420). Tap and drinking water samples were collected, samples of food contact surfaces were collected by swab-kit, and samples for foodservice workers' hands and gloves were prepared by glove juice method. Aerobic plate count (APC) and coliform bacterial populations were enumerated on plate count agar (PCA) and desoxycholate lactose agar, respectively. The presence of Escherichia coli, Salmonella, Listeria monocytogenes, and Staphylococcus aureus was also examined by biochemical identification tests. In addition, PCA agar for APCs and Baird-Parker agar for S. aureus were used to enumerate airborne microorganisms. Higher APCs (< 0 to 5.1 log CFU/mL) than acceptable level were generally observed in water samples, while low coliform counts were found in the samples. High APCs were enumerated in cooking utensils, foodservice workers, tableware, and foodservice surroundings, and coliforms were also found in the samples for both seasons. The presence of Salmonella was found from only 10% of plastic glove samples (summer), and the presence of L. monocytogenes was not observed in all samples. S. aureus was detected in some of water, cooking utensils, tableware, employees, and foodservice surroundings, and E. coli was observed in cooking utensils (10% to 20%; summer). No obvious airborne bacteria were detected. These results showed that sanitation practice in school foodservices should be improved, and the results may be useful in microbial assessment of school foodservices.
