Severe mucocutaneous (MCL) and diffuse (DCL) forms of American cutaneous leishmaniasis (ACL) are infrequent in Venezuela. Chemotherapy produces only transitory remission in DCL, and occasional treatment failures are observed in MCL. We have evaluated therapy with an experimental vaccine in patients with severe leishmaniasis. Four patients with MCL and 3 with early DCL were treated with monthly intradermal injections of a vaccine containing promastigotes of Leishmania (Viannia) braziliensis killed by pasteurization and viable Bacillus Calmette- Guerin. Clinical and immunological responses were evaluated. Integrity of protein constituents in extracts of pasteurized promastigotes was evaluated by gel electrophoresis. Complete remission of lesions occurred after 5-9 injections in patients with MCL or 7-10 injections in patients with early DCL. DCL patients developed positive skin reactions, average size 18.7 mm. All have been free of active lesions for at least 10 months. Adverse effects of the vaccine were limited to local reactivity to BCG at the injection sites and fever in 2 patients. Extracts of pasteurized and fresh promastigotes did not reveal differences in the integrity of protein components detectable by gel electrophoresis. Immunotherapy with this modified vaccine offers an effective, safe option for the treatment of patients who do not respond to immunotherapy with vaccine containing autoclaved parasites or to chemotherapy .

In these challenging financial times the use of research as a basis for effective health and social care cannot be overstated. 'Shaping the Future', a joint Public Health Agency and University of Ulster workshop (27 January) takes a fresh look at research within the Allied Health Professions (AHPs) to improve the care and experiences of people across Northern Ireland.The AHPs provide a wide range of services including physiotherapy, occupational therapy, radiography, podiatry, speech and language therapy and orthoptics.The nature of their work enables AHPs to carry out research that can rapidly benefit patient care and experience. 'Shaping the Future' will look at priorities for new AHP research and consider how existing research can be more effectively shared and used in health and social care development, rather than perhaps being limited to the academic world.Speaking at the event, Professor Bernie Hannigan, Director of Health and Social Care Research and Development (HSC R&D), aDivision of the PHA, said: "A sound base of evidence from research is vital for effective health and social care practice. I welcome this study as an important resource that will help generate new evidence and highlight the potential for existing evidence to be applied in practice. The evidence base points to beneficial innovations that use the most up-to-date knowledge and keep the service user at the centre of care practices. At this event, health and social care policy makers, commissioners, academics and researchers will be able to consider how they can do and use research to ensure our AHP services deliver the best outcomes for patients and are sufficiently cost-effective to be sustained."A recent study funded by HSC R&D was carried out by the University of Ulster working closely with leading AHPs, key stakeholders and service users* from throughout Northern Irealnd. Presenting the results of this study at the 'Shaping the Future' event will help to identify ways to gather evidence and contribute to innovative projects and programmes.Professor Suzanne McDonough, of the Health and Rehabilitation Sciences Research Centre at the University of Ulster, said: "In our study we used the Delphi technique, which is a structured process using a series of questionnaires, to gather information and gain consensus from AHP groups, stakeholders and service users."The results identified seven major priority areas for research. These ranged from: the need for more practice evaluation particularly in the areas of mental health, cancer, obesity; diabetes; chronic disease management (especially stroke and brain injury); the role of AHPs in health promotion; service delivery issues such as access to services and waiting times. This study provides an important road map for AHP research priorities. It is the first step in the process of identifying what research still needs to be undertaken, what research already exists but needs to be translated, and some of the processes that need to be in place to ensure that research is an integral part of the day-to-day practice of AHPs and of service delivery."

To make a comprehensive evaluation of organ-specific out-of-field doses using Monte Carlo (MC) simulations for different breast cancer irradiation techniques and to compare results with a commercial treatment planning system (TPS). Three breast radiotherapy techniques using 6MV tangential photon beams were compared: (a) 2DRT (open rectangular fields), (b) 3DCRT (conformal wedged fields), and (c) hybrid IMRT (open conformal+modulated fields). Over 35 organs were contoured in a whole-body CT scan and organ-specific dose distributions were determined with MC and the TPS. Large differences in out-of-field doses were observed between MC and TPS calculations, even for organs close to the target volume such as the heart, the lungs and the contralateral breast (up to 70% difference). MC simulations showed that a large fraction of the out-of-field dose comes from the out-of-field head scatter fluence (>40%) which is not adequately modeled by the TPS. Based on MC simulations, the 3DCRT technique using external wedges yielded significantly higher doses (up to a factor 4-5 in the pelvis) than the 2DRT and the hybrid IMRT techniques which yielded similar out-of-field doses. In sharp contrast to popular belief, the IMRT technique investigated here does not increase the out-of-field dose compared to conventional techniques and may offer the most optimal plan. The 3DCRT technique with external wedges yields the largest out-of-field doses. For accurate out-of-field dose assessment, a commercial TPS should not be used, even for organs near the target volume (contralateral breast, lungs, heart).

One of the main opportunistic fungal infections amongst immunocompromised individuals is oral candidosis, which has been found in up to 90% of human immunodeficiency virus (HIV)-infected patients. This study employed yeasts isolated from the saliva and oral cavities of 114 HIV-infected patients living in Campinas, São Paulo. Of the isolates, 57.8% were identified as Candida albicans and 42.1% as non-C. albicans. The latter isolates were subsequently identified as C. krusei (7.5%), C. lusitaniae (5.2%), C. tropicalis (4.6%), C. parapsilosis (4.6%), C. glabrata (2.8%), C. kefyr (1.7%), C. guilliermondii (1.7%), C. intermedia (1.1%), C. norvegensis (0.5%), and Rhodotorula rubra (1.7%). Susceptibility of the isolates to amphotericin B, fluconazole, miconazole, and itraconazole was also determined by a microdilution method adopted by the National Committee for Clinical Laboratory Standards. The isolates demonstrated various susceptibilities to the antifungal agents. In particular 29 C. albicans and 13 non-C. albicans isolates showed low susceptibility to FLCZ (> 64 µg/ml). This study revealed huge diversity of Candida species, in particular the increasing emergence of non-C. albicans associated with the oral flora of HIV-infected patients.

The prevalence of unhealthy drinking at all levels in Irish society poses serious issues in terms of the consequence to individuals concerned, as well as to society as a whole. The workplace offers a useful setting for early identification and intervention with new employees who may have pre-existing alcohol use disorder issues. This pilot study aimed to evaluate the effectiveness within the workplace of a brief Cognitive Behavioural Therapy (CBT) intervention in reducing participants binge and risky drinking behaviours. Twenty-six Irish Naval recruits volunteered to participate in this randomised controlled trial. The intervention was conducted over four consecutive one and a half hour weekly sessions. Participants completed four principle outcome measures at intake, termination of the intervention and at the two-month follow-up assessment. The Alcohol Use Disorders Identification Test (Babor, Higginis-Biddle, Saunders & Monterio, 2001) was used to measures participants’ consumption levels and frequency of binge or risky drinking. A Readiness Ruler (Miller, Zweben, Diclemente, & Rychtarik, 1992) was used to measure participants’ readiness to change drinking, while the Drinking Expectancy Questionnaire (Young & Oei, 1996) was used to measure participants’ beliefs pertaining to alcohol, and their ability to refuse alcohol in high-risk social surroundings. There were preliminary data in support of the intervention. There were interaction effects that approached statistical significance for both a reduction in participants’ binge drinking (p =. 064) and an increase in participants’ ability to refuse alcohol in high-risk social settings (p = .059). There was also a significant interaction effect (pThis resource was contributed by The National Documentation Centre on Drug Use.

BACKGROUND AND PURPOSE: The study aims to assess the recanalization rate in acute ischemic stroke patients who received no revascularization therapy, intravenous thrombolysis, and endovascular treatment, respectively, and to identify best clinical and imaging predictors of recanalization in each treatment group. METHODS: Clinical and imaging data were collected in 103 patients with acute ischemic stroke caused by anterior circulation arterial occlusion. We recorded demographics and vascular risk factors. We reviewed the noncontrast head computed tomographies to assess for hyperdense middle cerebral artery and its computed tomography density. We reviewed the computed tomography angiograms and the raw images to determine the site and degree of arterial occlusion, collateral score, clot burden score, and the density of the clot. Recanalization status was assessed on recanalization imaging using Thrombolysis in Myocardial Ischemia. Multivariate logistic regressions were utilized to determine the best predictors of outcome in each treatment group. RESULTS: Among the 103 study patients, 43 (42%) received intravenous thrombolysis, 34 (33%) received endovascular thrombolysis, and 26 (25%) did not receive any revascularization therapy. In the patients with intravenous thrombolysis or no revascularization therapy, recanalization of the vessel was more likely with intravenous thrombolysis (P = 0·046) and when M1/A1 was occluded (P = 0·001). In this subgroup of patients, clot burden score, cervical degree of stenosis (North American Symptomatic Carotid Endarterectomy Trial), and hyperlipidemia status added information to the aforementioned likelihood of recanalization at the patient level (P < 0·001). In patients with endovascular thrombolysis, recanalization of the vessel was more likely in the case of a higher computed tomography angiogram clot density (P = 0·012), and in this subgroup of patients gender added information to the likelihood of recanalization at the patient level (P = 0·044). CONCLUSION: The overall likelihood of recanalization was the highest in the endovascular group, and higher for intravenous thrombolysis compared with no revascularization therapy. However, our statistical models of recanalization for each individual patient indicate significant variability between treatment options, suggesting the need to include this prediction in the personalized treatment selection.

The effects of blood components, nerve-cord severance, and ecdysone therapy on the posterior midgut epithelial cells of 5th-instar Rhodnius prolixus nymphs 10 days after feeding were analyzed by transmission electron microscopy. Cutting the nerve-cord of the blood-fed insects partially reduced the development of microvilli and perimicrovillar membranes (PMM), and produced large vacuoles and small electrondense granules; insects fed on Ringer's saline diet exhibited well developed microvilli and low PMM production; swolled rough endoplasmatic reticulum and electrondense granules; Ringer's saline meal with ecdysone led to PMM development, glycogen particles, and several mitochondria in the cytoplasm; epithelial cells of the insects fed on Ringer's saline meal whose nerve-cord was severed showed heterogeneously distributed microvilli with reduced PMM production and a great quantity of mitochondria and glycogen in the cytoplasm; well developed microvilli and PMM were observed in nerve-cord severed insects fed on Ringer's saline meal with ecdysone; Ringer's saline diet containing hemoglobin recovered the release of PMM; and insects fed on human plasma showed slightly reduced PMM production, although the addition of ecdysone in the plasma led to a normal midgut ultrastructural organization. We suggest that the full development of microvilli and PMM in the epithelial cells depends on the abdominal distension in addition to ingestion of hemoglobin, and the release of ecdysone.

Tungiasis is an ectoparasitosis causing considerable pathology in endemic areas. Standard therapy consists of removing the embedded parasite with a sterile needle. There is no effective chemotherapy at hand. To fill this gap, a double-blinded randomized controlled trial with oral ivermectin was conducted. A total of 54 individuals (27 in the placebo group, 27 in the ivermectin group) was followed up for seven days. They presented a total of 192 lesions. Patients received either ivermectin (300 µg/kg body weight at a single dose, repeated after 24 h) or placebo. Outcome measures included the clinical stage of lesion, presence of erythema, pain, itching, signs of viability of the parasite, and total lysis of flea. The ratio of fleas with total lysis per total number of fleas was slightly higher in the ivermectin group; however, this difference was not statistically significant. There was no significant difference in any of the other outcome measures between the treatment and the placebo group. The results show that oral ivermectin is without any clinically significant efficacy against embedded sand fleas at the dose given.

BACKGROUND: Here, we aimed to determine the prevalence of erectile dysfunction (ED) among HIV-infected men and its association with components of antiretroviral therapy. METHODS: Cross-sectional data on sexual dysfunction were collected in the Swiss HIV Cohort Study (SHCS) between December 2009 and November 2010. Multilevel logistic regression models were used to estimate the association between ED and exposure to 24 different antiretroviral drugs from four drug classes. RESULTS: During the study period, 5,194 of 5,539 eligible men in the SHCS had a follow-up visit; 4,064 men answered a question on ED for the first time. Among these men, ED was experienced often by 459 (11%), sometimes by 543 (13%), rarely by 389 (10%), never by 2,526 (62%) and 147 (4%) did not know. ED was associated with older age, an earlier HIV diagnosis and depression. No association was found with any drug class; however, ED was associated with cumulative exposure to either zalcitabine (OR 1.29 per year of use; 95% CI 1.07, 1.55) or enfuvirtide (OR 1.28; 95% CI 1.08, 1.52). CONCLUSIONS: Around 1 in 10 men in the SHCS reported often experiencing ED. We found no association between ED and any drug class, but those exposed to zalcitabine or enfurvitide (drugs no longer or rarely used) were more likely to report ED; this second association was probably not causal.

This leaflet is for anyone who wants to know more about Cognitive Behavioural Therapy (CBT).It discusses how it works, why it is used, its effects, its side-effects, and alternative treatments. If you can't find what you want here, there are sources of further information at the end of this leaflet. What is CBT? It is a way of talking about: ï,§ how you think about yourself, the world and other people ï,§ how what you do affects your thoughts and feelings. CBT can help you to change how you think ('Cognitive') and what you do ('Behaviour'). These changes can help you to feel better. Unlike some of the other talking treatments, it focuses on the 'here and now' problems and difficulties. Instead of focusing on the causes of your distress or symptoms in the past, it looks for ways to improve your state of mind now. When does CBT help? CBT has been shown to help with many different types of problems. These include: anxiety, depression, panic, phobias (including agoraphobia and social phobia), stress, bulimia, obsessive compulsive disorder, post-traumatic stress disorder, bipolar disorder and psychosis. CBT may also help if you have difficulties with anger, a low opinion of yourself or physical health problems, like pain or fatigue. How does it work? CBT can help you to make sense of overwhelming problems by breaking them down into smaller parts. This makes it easier to see how they are connected and how they affect you. These parts are: ï,§ A Situation - a problem, event or difficult situation. From this can follow: ï,§ Thoughts ï,§ Emotions ï,§ Physical feelings ï,§ Actions Each of these areas can affect the others. How you think about a problem can affect how you feel physically and emotionally. All these areas of life can connect like this: {5 Areas - click related link below} What happens in one of these areas can affect all the others. There are helpful and unhelpful ways of reacting to most situations, depending on how you think about it. The way you think can be helpful - or unhelpful. An example: If you go home feeling depressed, you'll probably brood on what has happened and feel worse. If you get in touch with the other person, there's a good chance you'll feel better about yourself. If you avoid the other person, you won't be able to correct any misunderstandings about what they think of you - and you will probably feel worse. This 'vicious circle' can make you feel worse. It can even create new situations that make you feel worse. You can start to believe quite unrealistic (and unpleasant) things about yourself. This happens because, when we are distressed, we are more likely to jump to conclusions and to interpret things in extreme and unhelpful ways. CBT can help you to break this vicious circle of altered thinking, feelings and behaviour. When you see the parts of the sequence clearly, you can change them - and so change the way you feel. CBT aims to get you to a point where you can 'do it yourself', and work out your own ways of tackling these problems.

In order to assess the human immunodeficiency virus type 1 (HIV-1) drug resistance mutation profiles and evaluate the distribution of the genetic subtypes in the state of Rio de Janeiro, Brazil, blood samples from 547 HIV-1 infected patients failing antiretroviral (ARV) therapy, were collected during the years 2002 and 2003 to perform the viral resistance genotyping at the Renageno Laboratory from Rio de Janeiro (Oswaldo Cruz Foundation). Viral resistance genotyping was performed using ViroSeqTM Genotyping System (Celera Diagnostic-Abbott, US). The HIV-1 subtyping based on polymerase (pol) gene sequences (protease and reverse transcriptase-RT regions) was as follows: subtype B (91.2%), subtype F (4.9%), and B/F viral recombinant forms (3.3%). The subtype C was identified in two patients (0.4%) and the recombinant CRF_02/AG virus was found infecting one patient (0.2%). The HIV-1 genotyping profile associated to the reverse transcriptase inhibitors has shown a high frequency of the M184V mutation followed by the timidine-associated mutations. The K103N mutation was the most prevalent to the non-nucleoside RT inhibitor and the resistance associated to protease inhibitor showed the minor mutations L63P, L10F/R, and A71V as the more prevalent. A large proportion of subtype B was observed in HIV-1 treated patients from Rio de Janeiro. In addition, we have identified the circulation of drug-resistant HIV-1 subtype C and are presenting the first report of the occurrence of an African recombinant CRF_02/AG virus in Rio de Janeiro, Brazil. A clear association between HIV-1 subtypes and protease resistance mutations was observed in this study. The maintenance of resistance genotyping programs for HIV-1 failing patients is important to the management of ARV therapies and to attempt and monitor the HIV-1 subtype prevalence in Brazil.

Acute massive pulmonary embolism (PE) is a life-threatening event. Before the era of cardiopulmonary bypass, acute pulmonary embolectomy had been historically attempted in patients with severe hemodynamic compromise. The Klippel-Trenaunay syndrome (KTS) represents a significant life-long risk for major thromboembolic events. We present two young patients with Klippel-Trenaunay syndrome who survived surgical embolectomy after massive PE and cardiopulmonary resuscitation, with good postoperative recovery. Even though the role of surgical embolectomy in massive PE is not clearly defined, with current technology it can be life saving and can lead to a complete recovery, especially in young patients as described in this study.
