    Nearly 300 patients, admitted to hospital with acute purulent exacerbations of chronic respiratory disease, have been treated with various newer quinolones: 26 patients received enoxacin, 50 pefloxacin, 80 ciprofloxacin and 143 ofloxacin. Dosages varied from 400 mg once daily to 1000 mg twice daily. orally for five to 10 days. Patients were evaluated bacteriologically and clinically before, during and after treatment. Nearly all infections associated with Haemophilus influenzae and/or Branhamella catarrhalis were successfully eradicated. Some Streptococcus pneumoniae infections relapsed, some could not be eradicated, and a number of patients developed new infections with these organisms. Approximately half of the Pseudomonas aeruginosa infections were eradicated. Nearly all patients received concomitant theophylline but this only caused serious problems in those given 600 mg doses of enoxacin twice daily. Five patients given ciprofloxacin had to discontinue because of unwanted effects (mostly hallucinations), one patient given pefloxacin had gastric pain and two patients given ofloxacin developed a skin rash. Apart from the theophylline interaction, the unwanted effects did not appear to be dose-related. The best overall clinical results were noted after 800 mg doses of ofloxacin once daily for seven days. PMID:3438151

    At the end of 2013, the Government of Uganda issued guidance recommending provision of Anti-Retroviral Treatment (ART) to HIV-positive people in key populations, including female sex workers, regardless of CD4 cell count. We describe the implementation of this new guidance in a clinic serving women at high risk of HIV infection in Kampala. Between July and December 2015, we conducted repeat in-depth interviews with 15 women attending the clinic after the change in guidelines, to explore their perceptions regarding prompt ART initiation. The sample included some women who were HIV-negative and women who had both started and deferred ART. We conducted a data-led thematic analysis of the material from the interviews. A total of 257 of 445 eligible women had started ART; others were undecided or had not returned to the clinic after receiving the new information. Participants recounted varying experiences with the provision of prompt treatment. At an individual level, a history of treatment for opportunistic infections and other illnesses, coupled with relatively poor health, encouraged some to initiate ART promptly. However, knowledge of friends/relatives already on ART who had experienced side effects caused others to delay starting, fearing the same experience for themselves. A number of women questioned why they should start treatment when they were not sick. Situational factors such as work and residence (with many sharing single rooms) caused discomfort among newly diagnosed women who feared disclosure and stigma that would result from taking ART when they were not ill. Alcohol consumption and irregular working hours affected perceptions of future adherence, making prompt ART harder to embrace for some. Our findings show the challenges that influence the delay of treatment initiation, and/or the decision to defer receiving information on ART, with implications for the success of the test and treat programmes and guidelines.

  6. Bone infected/inflamed conditions: Clinical experience with RP517, a Tc99m-leukotriene B4 receptor antagonist

    International Nuclear Information System (INIS)

    Full text: Objectives: Tc 99m- RP517- is a receptor antagonist of Leukotriene B4 (LTB4) labelling predominantly neutrophils, in whole blood. The aim of this clinical trial was to obtain the best acquisition protocol and performance of this agent in detecting bone, joint and soft tissue infected / inflamed pathologies. Methods: RP517 was labelled with 15-20 mCi (555-740MBq) Tc99m per doses. Twenty-six patients studied (F 14, M 12) with range ages 19- 93, suspected of bone, joint and soft tissue infection (25) and one with fever of unknown origin (FUO). Laboratory data, anatomical images and one other scintiscan (MDP, Ga-67 or Tc99m- ciprofloxacin) were evaluated. Acquisition protocol: flow, 30 min, 1, 2, 3, 4 - 24h planar or Spect images as required. Results documented with histology, cultures or clinical follow up. Scans were classified as positive when abnormal uptake persisted in the 24h images or negative when positivity faded, or not detected in later images. Results: Labeling efficiency 86-90%. No adverse reactions encountered. Image protocol modified to a flow, 30 min, 4 and 24h images. Ten-fifteen % of in vivo leucocyte labelling at 1h. Early bile and intestinal excretion did not improve with cleansing enemas or food restrain. Late bone marrow activity is less visible than with in vitro leucocyte labeling. Only 16 patients had proven biopsies and cultures with coincident images in 8 True Positive; other 6 cases were True Negative, 2 False Negative (with positive Ga-67 and Tc99m-ciprofloxacin) and no False Positive. Sensitivity 80%, Specificity 100%. Conclusions: A kit should be produced in order to make it easily available. Pharmaceutically manipulation altering the excretion route could validate studies in abdominal infections and FUO that are now disesteemed. Protocol images must include 24h scans. Advantage of RP517 is the lack of cell labeling manipulation. Larger series must be studied to obtain statistics on joint bone and soft tissue infection

    Full Text Available Introduction Streptococcus suis is a bacterium causing a disease in pigs and rarely in humans. This zoonosis is mostly found as a sporadic disease in individuals that were in contact with the affected or infected pigs: farmers, veterinarians and workers engaged in fresh pork processing. It is assumed that the bacterium enters the body through a cut abrasion in the skin. Initially, the condition resembles a flu, followed by signs of bacteriemia and sepsis. The most frequent clinical manifestation of Streptococcus suis infection is meningitis, leading to hearing loss in over 75% of patients, and subsequent arthritis, endophtalmitis, endocarditis and pneumonia. Toxic shock syndrome with hemorhagic manifestations rarely develops. Material and methods This study included five male patients aged 22 to 63 years treated in the Intensive Care Unit of the Institute of Infectious and Tropical Diseases in Belgrade, due to Streptococcus suis infection. The aim of this study was to point to the existence of this bacteria in our environment, to describe clinical manifestations of the disease and to point out the importance of its prevention. Results All patients had epidemiological evidence of being in contact with pork meat. There were no data about diseased pigs. The estimated incubation period was 4 to 8 days. All patients had meningeal signs. Clinical symptoms included shivering, fever, vomiting, headache, malaise, vertigo and tinitus. Three patients presented with alerterd level of awareness. Four patients developed very severe bilateral hearing impairemnt, whereas one endophtalmtis and one developed endocarditis. The cerebrospinal fluid (CSF was opalescent in four patients, and only one patient presented with clear CSF. CSF examination showed typical changes characeteristic for bacterial meningitis. Streptoccocus suis was isolated in CSF in all patients, and in one patient the bacteria was isolated in blood as well. All patients underwent treatment with

    Streptococcal bone and joint infections are less common than staphylococcal cases. Few studies have reported the cases with well-identified Streptococcus species. Their clinical features and prognosis are not clearly known to date. Moreover, no treatment regimen has yet been clarified. We reviewed the streptococcal bone and joint infection cases managed in our centres from January 2009 to December 2013. We described the epidemiology, clinical and microbiologic characteristics, treatment approach and outcome. Among the 93 cases, 83% of patients were men with a median age of 60 years, and 90% of patients had comorbidities or risk factors. Bacteraemia occurred in 14% of cases. Serious complications occurred in six patients, including severe sepsis (two cases) and infective endocarditis (two cases). Orthopaedic device infections were observed in 35% of cases, including 17 patients with internal osteosynthesis device infection, 14 with prosthetic joint infection and three with vertebral osteosynthesis device infection. The median time between orthopaedic device implantation and onset of infection was 447 days. Fourteen species of Streptococcus were identified, including 97 isolates using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and three isolates using molecular identification. The five most represented species included S. agalactiae (37%), S. dysgalactiae (12%), S. anginosus (11%), S. constellatus (10%) and S. pneumoniae (9%). Streptococci isolates were susceptible to amoxicillin, with the exception of one S. mitis isolate. Remission 1 year after the end of treatment was recorded in 83%. One patient died of infection; eight patients had infections that failed to respond to treatment; and seven patients experienced relapse. Twenty patients (22%) had an unfavourable functional outcome, including 19 amputations and one arthrodesis. Five significant prognostic factors associated with an unfavourable clinical outcome were identified

    Full Text Available Larry M Bush1,2, Fredy Chaparro-Rojas3, Victor Okeh3, Joseph Etienne3 1Charles E Schmidt College of Medicine, Florida Atlantic University, Boca Raton, FL; 2University of Miami Miller School of Medicine, Miami, FL; 3Internal Medicine, University of Miami Miller School of Medicine Affiliated Program at JFK Medical Center, Atlantis, FL, USA Abstract: The treatment of urinary tract infections (UTIs continues to evolve as common uropathogens increasingly become resistant to previously active antimicrobial agents. In addition, bacterial isolates, which were once considered to be either colonizers or contaminants, have emerged as true pathogens, likely related to the more complex array of settings where health care is now delivered. Even though the reliability of many antimicrobial agents has become less predictable, the fluoroquinolone group of agents has remained a frequent, if not the most often prescribed, antimicrobial therapy for almost all types of UTIs. Levofloxacin has taken its position at the top of the list as one of the most regularly administered fluoroquinolone agents given to patients with a suspected or proven UTI. The authors review the clinical experience of the use of levofloxacin over the past decade and suggest that the use of levofloxacin for the treatment of UTIs, although still fairly dependable, is perhaps not the best use of this important antimicrobial agent. Keywords: fluoroquinolone, antimicrobial agent, UTI, resistance

  12. Intracranial Infections: Clinical and Imaging Characteristics

    International Nuclear Information System (INIS)

    The radiologist plays a crucial role in identifying and narrowing the differential diagnosis of intracranial infections. A thorough understanding of the intracranial compartment anatomy and characteristic imaging findings of specific pathogens, as well incorporation of the clinical information, is essential to establish correct diagnosis. Specific types of infections have certain propensities for different anatomical regions within the brain. In addition, the imaging findings must be placed in the context of the clinical setting, particularly in immunocompromised and human immunodeficiency virus (HIV)-positive patients. This paper describes and depicts infections within the different compartments of the brain. Pathology-proven infectious cases are presented in both immunocompetent and immunocompromised patients, with a discussion of the characteristic findings of each pathogen. Magnetic resonance spectroscopy (MRS) characteristics for several infections are also discussed

    Helicobacter pylori infection is recognised as a cause of gastritis and peptic ulcer disease (PUD) and usually acquired during the first years of life. While there is a decline in the prevalence of H. pylori infection in northern and western European countries, the infection is still common in southern and eastern parts of Europe and Asia. Symptoms of H. pylori-related PUD are nonspecific in children and may include epigastric pain, nausea and/or vomiting, anorexia, iron deficiency anaemia and hematemesis. Besides, only a small proportion of children develop symptoms and clinically relevant gastrointestinal disease. H. pylori infection can be diagnosed either by invasive tests requiring endoscopy and biopsy or non-invasive tests including the (13)C-urea breath test, detection of H. pylori antigen in stool and detection of antibodies in serum, urine and saliva. The aim of treatment is at least 90 % eradication rate of the bacteria, and a combination of two antibiotics plus a proton pump inhibitor has been recommended as first-line treatment. However, frequent use of antibiotics during childhood is associated with a decline in eradication rates and the search for new treatment strategies as well. This is an overview of the latest knowledge and evidence-based guidelines regarding clinical presentation, diagnosis and treatment of H. pylori infection in childhood. PMID:23015042

    Full Text Available Introduction. Brucellosis is an acute, subacute or chronical disease, from the zoonosis group, caused by various types of bacteria belonging to genus Brucellae. It is transmitted to humans from domestic animals: goats, sheep, cattle, pigs and dogs. The course of the disease may either be asymptomatic, or produce a variety of clinical manifestations, ranging from light ones to extremely severe clinical forms. The aim of the study was to follow the clinical features of brucella infection in the hospital-treated patients, as well as its course and outcome. Material and Methods. The investigation included 15 patients, treated for brucella infection at the Clinic for infectious diseases during the last two years (2004 and 2005. Results. All patients were adults, their age ranged from 18 to 71, 49.96 on average. The epidemiological questionnaire was positive in all patients, confirming contacts with the ailing animals, or consumption of cheese made from milk of diseased animals. They all exhibited the classic symptoms - increased body temperature and shiver, fever, sweating, malaise and headache, the so called flu like state. The serum agglutination test was positive in respect to brucellosis, the titre ranged from 1:80 to 1:1280. Eight patients suffered excessive back pain, accompanied with impeded walk. In half of them magnetic resonance imaging confirmed the spondylodiscitis diagnosis. Three patients had clinical features of knee arthritis, two had bronchopneumonia, one pancreatitis, and one developed the signs of an acute kidney insufficiency. The outcome was favorable in all patients - They recuperated or healed completely. In one patient a relapse occurred, leading to the chronic course of the illness. Discussion. Although predominantly Mediterranean Brucellosis is a worldwide spread disease. During the last two years, an increased incidence of the disease has been observed. Conclusion. Due to the variety of clinical futures and the possibility

    Full Text Available Filovirus infection presents many unique challenges to patient management. Currently no approved treatments are available, and the recommendations for supportive care are not evidence based. The austere clinical settings in which patients often present and the sporadic and at times explosive nature of filovirus outbreaks have effectively limited the information available to evaluate potential management strategies. This review will summarize the management approaches used in filovirus outbreaks and provide recommendations for collecting the information necessary for evaluating and potentially improving patient outcomes in the future.

    Full Text Available Neurocognitive disorders are emerging, probably underestimated, complications in HIV-infected people. The aim of the study was to assess neurocognitive profiles of newly detected HIV-infected patients. We performed an observational retrospective single-cohort study. Illiterates and patients with neurologic symptoms or previous psychiatric diagnosis were excluded. Neuropsychological profiles were assessed using a validated battery of neuropsychological tests. We included 206 patients; with males representing the majority of them (85%. Risk factors for HIV acquisition were unprotected sexual intercourse (homo/bisexual in 39.8% and heterosexual in 60.2%. Thirty-nine patients (18.9% were previous injection drug users, while 41 (19.9% were alcohol abusers. Mean education was 11.1 years (SD—standard deviation—3.7. A high prevalence of HIV-associated neurocognitive disorders (HAND, 47.1% was present in HIV-infected patients: particularly, asymptomatic neurocognitive impairment (ANI was found in 30.6%, mild neurocognitive disorder (MND in 15% and HIV-associated dementia (HAD in 1.5%. Male gender, low degree of education, AIDS diagnosis and gepatitis B virus (HBV co-infection were factors independently associated with HAND in a multivariable logistic regression model. Our data suggest that patient-specific factors and AIDS diagnosis have a certain kind of impact in HAND occurrence. A complete neuropsychological screening must be recommended in all patients at HIV-infection diagnosis.

    Full Text Available Abstract Background Some people living with HIV/AIDS (PLHIV want to have children while others want to prevent pregnancies; this calls for comprehensive services to address both needs. This study explored decisions to have or not to have children and contraceptive preferences among PLHIV at two clinics in Uganda. Methods This was a qualitative cross-sectional study. We conducted seventeen focus group discussions and 14 in-depth interviews with sexually active adult men and women and adolescent girls and boys, and eight key informant interviews with providers. Overall, 106 individuals participated in the interviews; including 84 clients through focus group discussions. Qualitative latent content analysis technique was used, guided by key study questions and objectives. A coding system was developed before the transcripts were examined. Codes were grouped into categories and then themes and subthemes further identified. Results In terms of contraceptive preferences, clients had a wide range of preferences; whereas some did not like condoms, pills and injectables, others preferred these methods. Fears of complications were raised mainly about pills and injectables while cost of the methods was a major issue for the injectables, implants and intrauterine devices. Other than HIV sero-discordance and ill health (which was cited as transient, the decision to have children or not was largely influenced by socio-cultural factors. All adult men, women and adolescents noted the need to have children, preferably more than one. The major reasons for wanting more children for those who already had some were; the sex of the children (wanting to have both girls and boys and especially boys, desire for large families, pressure from family, and getting new partners. Providers were supportive of the decision to have children, especially for those who did not have any child at all, but some clients cited negative experiences with providers and information gaps for

    2012-04-01

    Full Text Available Abstract Background Chicken meat and eggs can be a source of human zoonotic pathogens, especially Salmonella species. These food items contain a potential hazard for humans. Chickens lines differ in susceptibility for Salmonella and can harbor Salmonella pathogens without showing clinical signs of illness. Many investigations including genomic studies have examined the mechanisms how chickens react to infection. Apart from the innate immune response, many physiological mechanisms and pathways are reported to be involved in the chicken host response to Salmonella infection. The objective of this study was to perform a meta-analysis of diverse experiments to identify general and host specific mechanisms to the Salmonella challenge. Results Diverse chicken lines differing in susceptibility to Salmonella infection were challenged with different Salmonella serovars at several time points. Various tissues were sampled at different time points post-infection, and resulting host transcriptional differences investigated using different microarray platforms. The meta-analysis was performed with the R-package metaMA to create lists of differentially regulated genes. These gene lists showed many similarities for different chicken breeds and tissues, and also for different Salmonella serovars measured at different times post infection. Functional biological analysis of these differentially expressed gene lists revealed several common mechanisms for the chicken host response to Salmonella infection. The meta-analysis-specific genes (i.e. genes found differentially expressed only in the meta-analysis confirmed and expanded the biological functional mechanisms. Conclusions The meta-analysis combination of heterogeneous expression profiling data provided useful insights into the common metabolic pathways and functions of different chicken lines infected with different Salmonella serovars.

    The analgesic efficacy of tramadol has been recently reassessed as part of a new clinical development programme to support an application for registration in the USA. This article reviews the results of single dose and short term studies of oral tramadol 50, 75, 100 and 150 mg in various acute pain conditions. In a double-blind single dose study conducted in 161 patients with severe pain following caesarean section, tramadol 75 and 150 mg and the combination of paracetamol 650 mg with dextropropoxyphene napsylate 100 mg were shown to be effective and statistically superior to placebo. The results from this and 17 other similar studies in patients with pain after surgery (n = 1594) or dental extraction (n = 1859) including other comparators were included in a pooled analysis. Tramadol 100 mg was the optimal single dose for acute pain and tramadol 50 mg showed similar analgesic efficacy to codeine 60 mg. Multiple dose short term studies (n = 520) with tramadol 50, 75 and 100 mg demonstrated a statistically significant and dose-dependent reduction in the consumption of either ibuprofen or morphine as escape medication. New pharmacokinetic data show that steady-state plasma tramadol concentrations reached after oral administration of 50 mg doses every 6 hours are similar to those obtained after administration of a 100 mg single oral dose (250 micrograms/L). This rationale is supported by the results of long term studies in which the average daily dose of tramadol was approximately 250 mg. PMID:7517826

    To determine the frequency of dengue as a cause of fever and compare the clinical and haematological characteristics of Dengue-probable and Dengue-proven cases. All patients with age above 14 years, who were either hospitalized or treated in medical outdoor clinic due to acute febrile illness, were evaluated for clinical features of Dengue Fever (DF), Dengue haemorrhagic fever (DHF) and Dengue Shock Syndrome (DSS). Patients showing typical clinical features and haematological findings suggestive of Dengue fever (As per WHO criteria) were evaluated in detail for comparison of probable and confirmed cases of Dengue fever. All other cases of acute febrile illness, not showing clinical features or haematological abnormalities of Dengue fever, were excluded. The clinical and laboratory features were recorded on SPSS 11.0 programme and graded where required, for descriptive and statistical analysis. Out of 5200 patients with febrile illness, 107 (2%) presented with typical features of DF, 40/107 (37%) were Dengue-proven while 67/107 (63%) were Dengue-probable. Out of Dengue-proven cases, 38 were of DF and 2 were of DHF. Day 1 temperature ranged from 99-105 degreeC (mean 101 degree C). Chills and rigors were noticed in 86 (80%), myalgia in 67%, headache in 54%, pharyngitis in 35%, rash in 28%, and bleeding manifestations in 2% cases.

    The impact of infectious diseases on older adults is far greater than on younger adults because of significantly higher morbidity and mortality caused by infection. The reasons for this greater impact include factors such as lower physiologic reserve due to age and chronic disease, age-related changes in host defenses, loss of mobility, higher risk for polypharmacy and adverse drug reactions, and being on drugs that increase the risk for infection (e.g., anticholinergic and other sedating medications increase the risk for pneumonia).

    Full Text Available OBJECTIVE: The purpose of this study was to evaluate whether individuals consider their HCV infection to be a potentially traumatic experience. Additionally, we investigated its association with Post-Traumatic Stress Disorder (PTSD and the impact of PTSD diagnosis on health-related quality of life (HRQoL in HCV infected subjects. METHODS: We conducted a cross-sectional survey of 127 HCV-infected outpatients recruited at a University Hospital in Salvador, Brazil. All subjects answered an orally-administered questionnaire to gather clinical and socio-demographic data. We investigated traumatic experiences and the subject's perception of the disease using the Trauma History Questionnaire. PTSD and other psychiatric diagnoses were assessed through the Mini International Neuropsychiatric Interview-Brazilian Version 5.0.0 (M.I.N.I. PLUS. HRQoL was assessed using Short-Form 36 (SF-36. RESULTS: Approximately 38.6% of the patients considered hepatitis C to be a traumatic experience. Of these, 60.7% had a PTSD diagnosis. PTSD was associated with significant impairment in quality of life for individuals in seven SF-36 domains as shown bymultivariate analysis: Role-Physical (β: -24.85; 95% CI: -42.08; -7.61, Bodily Pain (β: -19.36; 95% CI: -31.28; -7.45, General Health (β: -20.79; 95% CI: -29.65; -11.92, Vitality (β: -11.92; 95% CI: -20.74; -3.1, Social Functioning (β: -34.73; 95% CI: -46.79; -22.68, Role-Emotional (β: -26.07; 95% CI: -44.61; -7.53, Mental Health (β: -17.46; 95% CI: -24.38; -10.54.

    Full Text Available Dengue is an important global public health problem. The World Health Organization estimates that 2/5 of entire world population are in risk of dengue infection. Almost 50 millions cases occur annually, with at least 20 thousand deaths. The etiological agent of this acute febrile disease is a single-strand positive-sense RNA virus of Flavivirus genus. It is an arboviral disease transmitted by Aedes sp. mosquitoes (Aedes aegypti and A. albopictus. Most infected individuals present asymptomatic infection, but some may develop clinical signs. Therefore, a wide spectrum of illness can be observed, ranging from unapparent, mild disease, called dengue fever, to a severe and occasionally fatal dengue hemorrhagic fever/dengue shock syndrome. Currently, neurological manifestations related to dengue infections are increasingly been observed and appears as a challenge for medical practice. In this study the neurological complications of dengue infection will be reviewed, focusing a better understanding of the disease for the clinical practice.

  4. Clinical efficacy of ciprofloxacin in lower respiratory tract infections.

    Pedersen, S S

    1989-01-01

    The sputum pharmacokinetics and clinical efficacy of ciprofloxacin in lower respiratory tract infections is reviewed. Following intravenous administration, ciprofloxacin penetrates rapidly into bronchial tissue; the elimination half life is between 3 and 4 h and a dose dependency is seen. Following oral intake, the time to reach maximal concentrations is approximately two hours and after a dose of 750 mg the concentration may reach 1.7 mg/l in patients without cystic fibrosis and range from 0.5 to 3.4 mg/l in cystic fibrosis patients. Coadministration of ciprofloxacin increases serum levels and decreases total body clearance of theophylline. In controlled comparative clinical trials, ciprofloxacin has been found to have similar clinical efficacy as amoxycillin, ampicillin, cefalexin, doxycycline, co-trimoxazole, imipenem-cilastatin and ceftazidime for the treatment of a range of lower respiratory tract infections. Ciprofloxacin has been found to be superior in clinical efficacy to cefaclor. Experimental animal models suggest a role for ciprofloxacin in infections caused by Legionella pneumophila and Mycoplasma pneumoniae. The clinical and bacteriological efficacy of ciprofloxacin is less pronounced in lung infections caused by Pseudomonas aeruginosa, but is comparable to the combination of beta-lactams and aminoglycosides. Development of resistance is frequently observed during ciprofloxacin treatment of Ps. aeruginosa. Because of the availability of other oral and effective agents, ciprofloxacin is not recommended for empirical treatment of community acquired lower respiratory infections, but should be reserved for infections caused by multiply resistant organisms.

  5. The clinical experiences of dyslexic healthcare students

    International Nuclear Information System (INIS)

    This paper reflects on the experiences of healthcare students with dyslexia in order to raise awareness of the potential challenges for dyslexic student radiographers and their clinical educators. With widening participation policies it is likely that the number of student radiographers with specific learning difficulties such as dyslexia will continue to increase. A review of the literature associated with dyslexia in healthcare education was performed in order to provide an overview of the current position. Although Higher Education Institutions (HEIs) have embraced the support and learning opportunities for dyslexic students at university, evidence would suggest that this is not reflected in the clinical departments. The current literature strongly suggests that since the risk of errors with clinical information is far more significant within the clinical placement, there is an immediate requirement for greater understanding, robust support and risk assessment systems. This review considers the problems experienced by dyslexic students, coping strategies they employ and the possible implications for clinical radiography education.

    Full Text Available Since the 1960s, regular hemodialysis (HD was recognized as a risk factor for the development of infective endocarditis (IE, particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving re-gular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Sta-phylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphlococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity.

    Full Text Available Poor perineal wound healing and infections after proctectomy surgery cause a significant proportion of physical and psychological morbidities, such as pain, leakage, and abscesses. In the long run, some of these symptoms will lead to extended periods of hospitalization. These kinds of postoperative complications are also associated with delays in possible chemotherapy treatment. The aim of this study was to describe patient experiences of perineal wound infections following proctectomy due to rectal cancer, and the importance of the communication with and the self-care support from the nurse for these patients. Five women and five men (61–87 years, median age 71 years were included and interviewed. A qualitative content analysis of the interviews was carried out and the following main categories emerged: “Managing postoperative complications,” “Being independent,” “Feeling safe,” and “Accepting the situation.” A perineal wound infection after a proctectomy is devastating for the individual patient. The limitations and changes to the patients’ lives turn into new daily routines, which force them to find new ways to live and to accept the situation. For many of them, the infections remained for several months and, sometimes, for years. The ability to lead an independent life is drastically reduced, but through continuity in care it is possible to create a feeling of safety. Information, communication, and self-care support are all important and valuable factors for recovery. Specialized care containing an action plan is therefore needed in clinical practice to reduce the number of perineal wound infections postoperatively and should be initiated when the patient is discharged from the ward and continue until recovery.

    Full Text Available Annette Burgess,1 Kim Oates,2 Kerry Goulston,2 Craig Mellis1 1Central Clinical School, Sydney Medical School, The University of Sydney, Sydney, NSW, Australia; 2Sydney Medical School, The University of Sydney, Sydney, NSW, Australia Background: Bedside teaching lies at the heart of medical education. The learning environment afforded to students during clinical tutorials contributes substantially to their knowledge, thinking, and learning. Situated cognition theory posits that the depth and breadth of the students' learning experience is dependent upon the attitude of the clinical teacher, the structure of the tutorial, and the understanding of tutorial and learning objectives. This theory provides a useful framework to conceptualize how students' experience within their clinical tutorials impacts their knowledge, thinking, and learning. Methods: The study was conducted with one cohort (n=301 of students who had completed year 1 of the medical program at Sydney Medical School in 2013. All students were asked to complete a three-part questionnaire regarding their perceptions of their clinical tutor's attributes, the consistency of the tutor, and the best features of the tutorials and need for improvement. Both quantitative and qualitative data were collected and analyzed using descriptive statistics. Results: The response rate to the questionnaire was 88% (265/301. Students perceived that their tutors displayed good communication skills and enthusiasm, encouraged their learning, and were empathetic toward patients. Fifty-two percent of students reported having the same communications tutor for the entire year, and 28% reported having the same physical examination tutor for the entire year. Students would like increased patient contact, greater structure within their tutorials, and greater alignment of teaching with the curriculum. Conclusion: Situated cognition theory provides a valuable lens to view students' experience of learning within the

    Full Text Available Chicken infectious anemia (CIA is widespread viral disease in countries with the intensive poultry industry. In susceptible birds CIAV causes anemia subcutaneous and intramuscular hemorrhages, lymphoid tissue atrophy immunosuppression, cachexia and increased mortality. Protection of progeny relies not only on age resistance but also on maternally delivered antibodies (Mabs so possessing the information on level and persistence of Mabs is of great significance. In our study experimental infection with CIAV was performed on one and seven days old broiler chickens from naturally infected parent flock during the rearing period. In infected birds, clinical signs hematological findings and humoral immune response were examined. After euthanasia, we looked for specific pathomorphological and histopathological changes that indicate the presence of CIAV infection. In all one and seven days old chickens maternally derived antibodies were established. No clinical signs of CIA were observed, hematological findings showed no deviation from referent values, and there were no specific pathomorphological and histopathological changes at postmortem examination. According to previous knowledge, only serological negative flock if infected in time of laying represent risk for vertical transmission to progeny where typical disease with mortality will appear. The absence of Mabs in one day old chickens is critical point in break of disease. Typical clinical picture in day old chickens rises only when vertical transmission occurs.

    Pasteurella multocida is a common commensal of the gastrointestinal and respiratory tracts of animals, especially cats and dogs. It is transmitted to humans through contact with animals. Bite wound infection is the most common clinical manifestation. Systemic infections are unusual and mainly affect immunocompromised individuals. The article presents two cases of Pasteurella infection. Wound infection in a 75-year-old female following a bite from her pet cat was associated with bacteremia. The disease course was favorable with the initial clindamycin treatment despite in vitro resistance. The other patient was a 62-year-old female diagnosed with acute bacterial meningitis with multiple brain abscesses and transient expressive aphasia. She reported frequent contacts with pets and domestic animals without a recent bite. Hematogenous dissemination of the infection was suspected. Because of poor therapeutic response, cefotaxime was switched to chloramphenicol which was later switched to a combination of cefotaxime with ciprofloxacin due to anemia. Following 6 weeks of intravenous antibiotic therapy and another 10 weeks of oral ciprofloxacin therapy, magnetic resonance imaging showed normal results and the neurological defect resolved. Epidemiological, clinical and therapeutic aspects of Pasteurella infection are discussed and literature is reviewed. PMID:26312375

    Ninety cases of infective endocarditis seen over a 10-year-period at University College Hospital, Ibadan, are reviewed. The peak incidence was in the third decade and rheumatic heart disease was the commonest pre-existing lesion in 59 cases with subacute endocarditis. In most cases the source of infection was not known. In 41 of the 90 cases (44%) the diagnosis was made only at autopsy. The bacterial isolation rate was low, the commonest organisms being staphylococci, streptococci, micrococci and gramnegative bacilli. The overall mortality was 70%. A plea is made for increasing awareness of the disease and prompt institution of effective treatment. PMID:941246

    Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with a global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FIV can cause an acquired immunodeficiency syndrome that increases the risk of developing opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia) and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less important as a deadly infectious agent as in the last 20 years prevalence has been decreasing in most countries. PMID:21807418

    Full Text Available Dengue viral infections are common worldwide. Clinical manifestations form a broad spectrum, and include uncomplicated dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. Encephalopathy has been well reported and has classically been thought to result from the multisystem derangement that occurs in severe dengue infection; with liver failure, shock, and coagulopathy causing cerebral insult. However, there is increasing evidence for dengue viral neurotropism, suggesting that, in a proportion of cases, there may be an element of direct viral encephalitis. Understanding the pathophysiology of dengue encephalopathy is crucial toward developing a more effective management strategy. This review provides an overview of the clinical spectrum of dengue infection, and examines evidence supporting the existence of dengue encephalitis.

    Senior nursing students were interviewed in this study to better understand the clinical learning experience from the students' point of view. Results of the study revealed that the nursing students were indeed learning in their clinical experience. The major categories of learning were classified as nursing skills, time management, and professional socialization. The quality of learning was reportedly affected by the quality of the student's preparation, characteristics of the instructor, and the variety of clinical opportunities to which students were exposed. The data also reflected a pattern of student development which was separated into three stages. The first stage was permeated with anxiety and obsession with the rules of task performance. The second stage was a difficult transition period where students struggled with identifying the roles of nurses. During the final stage, the students become more comfortable with performing nursing tasks and become interested in expanding their role and becoming more independent. As the students strived for independence, they identified more closely with staff nurses and withdrew from instructors. PMID:3035128

    2016-03-01

    Burkholderia pseudomallei (B. pseudomallei), a causative agent of an emerging infectious disease melioidosis, is endemic in the tropical regions of the world. Due to increased international travel, the infection is now also seen outside of the tropics. The majority of patients with identified risk factors such as diabetes mellitus, heavy alcohol use, malignancy, chronic lung and kidney disease, corticosteroid use, thalassemia, rheumatic heart disease, systemic lupus erythematosus and cardiac failure acquire this organism through percutaneous inoculation or inhalation. The clinical manifestations are variable, ranging from localized abscess formation to septicemia. Melioidotic bone and joint infections are rarely reported but are an established entity. The knee joint is the most commonly affected joint in melioidosis, followed by the ankle, hip and shoulder joints. Melioidosis should be in the differential diagnosis of bone and joint infections in residents or returning travelers from the endemic area. Melioidosis diagnosis is missed in many parts of the world due to the lack of awareness of this infection and limited laboratory training and diagnostic techniques. It also mimics other diseases such as tuberculosis. Delay in the diagnosis, or the initiation of appropriate and effective treatment against melioidosis, could worsen the outcome. Initial therapy with ceftazidime, or carbapenem with or without cotrimoxazole is recommended, followed by the oral eradication therapy (based on the antimicrobial susceptibility) with amoxicillin/clavulanic acid or cotrimoxazole. Surgical intervention remains important. This paper reviews current literature on the epidemiology, clinical features, diagnosis, and management of melioidotic bone and joint infections.

  10. Clinical experience with PACS: Digital radiology

    International Nuclear Information System (INIS)

    We present our experience during the first 21 months of using hospital-wide network technology and digital archiving in connection with digital radiology in the Radiology Department at the SMZO/Danube hospital in Vienna. This means digital generation, archiving and distribution of radiographs as well as monitor reporting embedded in HIS and RIS. The clinical use of PACS demands full integration of all subsystems and modalities in a digital way, as was first realized at the Danube Hospital. With this approach, a reduction in radiation dose, improved communication and thus a reduction in the length of hospital stay and health care cost are attained. (orig.)

  11. Experimental evolution can unravel the complex causes of natural selection in clinical infections.

    2015-06-01

    It is increasingly clear that rapid evolutionary dynamics are an important process in microbial ecology. Experimental evolution, wherein microbial evolution is observed in real-time, has revealed many instances of appreciable evolutionary change occurring on very short timescales of a few days or weeks in response to a variety of biotic and abiotic selection pressures. From clinical infections, including the chronic bacterial lung infections associated with cystic fibrosis that form a focus of my research, there is now abundant evidence suggesting that rapid evolution by infecting microbes contributes to host adaptation, treatment failure and worsening patient prognosis. However, disentangling the drivers of natural selection in complex infection environments is extremely challenging and limits our understanding of the selective pressures acting upon microbes in infections. Controlled evolution experiments can make a vital contribution to this by determining the causal links between predicted drivers of natural selection and the evolutionary responses of microbes. Integration of experimental evolution into studies of clinical infections is a key next step towards a better understanding of the causes and consequences of rapid microbial evolution in infections, and discovering how these evolutionary processes might be influenced to improve patient health.A video of this Prize Lecture, presented at the Society for General Microbiology Annual Conference 2015, can be viewed via this link: Michael A.

    Full Text Available Background: Dermatophytoses refer to superficial fungal infection of keratinized tissues caused by keratinophilic dermatophytes. According to observations worldwide, dermatophytoses are the most common of the superficial fungal infections. It is common in tropics and may present in epidemic proportions in areas with high rates of humidity. Although common, the precise size of the problem defies measurement. Aims: The present study was undertaken to assess the clinical profile of dermatophytic infection and to identify the species of fungi that are prevalent in this region. Materials and Methods: A total of 100 patients clinically suspected for dermatophytoses were selected for the study. Direct microscopy in 10% potassium hydroxide (KOH and culture was done in each case. Results: Out of 100 patients, the maximum were seen in the age groups of 16-30 years. Tinea corporis was the most common clinical type (44.3% followed by tinea cruris (38.2%. Overall positivity by culture was 39% and by direct microscopy 96%. Conclusion: Trichophyton rubrum was the predominant species isolated (67.5% in all clinical types followed by Trichophyton mentagrophytes. Culturing the fungus may identify the species, but it is not essential for the diagnosis as it is not a sensitive test.

    Full Text Available Introduction Nosocomial infections (NIs are a serious health problem in hospitals worldwide and are followed by a series of consequences, medical, judicial, ethical and economic. Objective The main aim of this study was to assess the magnitude of NIs at the Clinical Centre in Kragujevac. Methods A prevalence study of nosocomial infections was conducted from 16th till 20th May, 2005, within Second National Prevalence Study of Niš in the Republic of Serbia. Results The study included 866 patients. 40 patients had a NI, thus the prevalence of patients with NIs and prevalence of NIs was the same, 4.6%. Among NIs, the most frequent were urinary infections (45.0% followed by surgical-site infections (17.5%, skin and soft tissue infections (15% and pneumonia (12.5%. The rate of NIs was highest at departments of orthopaedics and traumatological surgery (12.0%, followed by intensive care units (8.0%. Overall, 67.5% (27/40 NIs were culture-proved; the leading pathogens were Escherichia coli (40.0%, followed by gram-negative bacteria (Pseudomonas species, Proteus mirabilis, Enterobacteriaceae with equal frequency of 8.0%. Nosocomial infections were significantly more frequent in patients aged ≥65 years (p<0.05, with longer hospitalization ≥8 days (p<0.00, in intensive care patients (p<0.05, patients with an intravenous catheter (p<0.00, urinary catheter (p<0.00, and those under antibiotic therapy (p<0.00. Conclusion This study showed that the prevalence of nosocomial infections in our hospital is similar to the prevalence in the developed countries. The study of prevalence provides a prompt insight into basic epidemiological and ethiological characteristics of nosocomial infections, hence identification of hospital priorities and the need to undertake appropriate prevention measures. .

    Papillomaviruses are a large and diverse group of viruses. It includes approximately 200 fully described types that have been detected in humans. Human papilloma viruses (HPV) are etiologic agents during various, benign and malignant lesions of mucous membrane and skin epithelium. Very importantly, persistent HPV infection of certain types is a leading cause of carcinoma of uterine cervix, penis, vulva; vagina, anal canal and fauces (including tongue base and tonsils). HPV infection prophylaxis is the best means to control HPV-conditioned diseases, and vaccination, as had been demonstrated, --the most effective method of its prophylaxis. In this paper principle characteristics and clinical manifestations of papillomavirus infection, as well as effectiveness of vaccination against HPV are examined. PMID:27029121

    Occult hepatitis B virus (HBV) infection (OBI) is defined as the presence of HBV DNA in the liver (with or without detectable HBV DNA in serum) for individuals testing HBV surface antigen negative. Until recently, the clinical effect of OBI was unclear on the progression of liver disease; on the development of hepatocellular carcinoma; and on the risk for reactivation or transmission of HBV infection. Several studies suggest a high prevalence of OBI among patients with cryptogenic chronic liver disease, but its role in the progression to cirrhosis remains unclear. Although OBI has been well documented in human immunodeficiency virus (HIV)-positive patients, especially among those coinfected with hepatitis C virus, further studies are needed to determine its current clinical impact in HIV setting.

    Pivmecillinam (PMPC), semisynthetic penicillin for oral use, was studied clinically and following results were obtained. 1) Twenty-eight patients with acute simple cystitis treated with the drug 200 mg/day for 4 days, clinical results were excellent in 23 cases and moderate in 5 cases. Six patients with chronic simple cystitis treated with the drug 400 mg/day for 7 days, clinical results were excellent in 4 cases, moderate in 1 case and poor in 1 case. Eight patients with complicated urinary tract infections treated with the drug 400 mg/day for 7 days, clinical results were excellent in 2 cases, moderate in 2 cases and poor in 4 cases. Overall effectiveness amounted to 88.1%. 2) Pivmecillinam was clinically effective in patients infected by Gram-negative bacteria except Pseudomonas aeruginosa. 3) No side effects were observed in all cases. The effectiveness of PMPC for acute simple cystitis was compared with that of talampicillin (TAPC), ampicillin (ABPC), amoxicillin (AMPC) and pivampicillin (PVPC) reported previously and PMPC was assessed as the most useful agent in these. Then, pivmecillinam should be chosen firstly as a chemotherapeutic agent for acute simple cystitis. PMID:228097

    Full Text Available Abstract Background Norovirus is an important cause of nonbacterial acute gastroenteritis in all ages. Atypical courses are described. Clinical symptoms are diarrhea, vomiting, nausea, abdominal cramps, fever and malaise. Apart from three recent short reports we describe for the first time an outbreak of norovirus in a tertiary Neonatal Intensive Care Unit. Findings The typical symptoms of norovirus infection are in part also seen in premature born infants but with a different pattern and a huge variety of clinical courses. Vomiting is not the main symptom of norovirus infection in premature infants but distended abdomen and other symptoms such as apnea, gastric remainders or sepsis like appearance. The course in premature born patients could be explained by an immunocompromised mice model. Extensive hygienic measures were necessary to control the outbreak without closing the Neonatal Intensive Care Unit. Conclusion Norovirus infection in premature infants shows an impressive pattern of a wide variety of clinical courses. Only the consequent use of different hygienic pattern can lead to elimination of norovirus.

    Rapid developments in infection biology create new and exciting options for individualized diagnostics and therapy. Such new practices are needed to improve patient survival and reduce morbidity. Molecular determinants of host resistance to infection are being characterized, making it possible to identify susceptible individuals and to predict their risk for future morbidity. Immunotherapy is emerging as a new strategy to treat infections worldwide and controlled boosting of the host immune defense represents an important therapeutic alternative to antibiotics. In proof of concept studies, we have demonstrated that this approach is feasible. The long-term goal is not just to remove the pathogens but to also develop technologies that restore resistance to infection in disease-prone patients and devise personalized therapeutic interventions. Here, we discuss some approaches to reaching these goals, in patients with urinary tract infection (UTI). We describe critical host signaling pathways that define symptoms and pathology and the genetic control of innate immune responses that balance protection against tissue damage. For some of these genes, human relevance has been documented in clinical studies, identifying them as potential targets for immune-modulatory therapies, as a complement to antibiotics. PMID:26927188

    Objective To discuss thepathogenesis, etiology, clinical manifestations, diagnosis, treatment and prognosis of right-sided infective endocarditis (RIE) . Methods To investigate retrospectively the clinical data of patients with RIE admitted in our hospital from Jan 1985 to Dec 2000.Results There were 17 cases of RIE (12 male, 5female, mean age 22 years), among which 7 with congenital heart disease, 1 with pacemaker implantation and 9 with a history of intravenous drug abuse but without underlying heart disease. Fever and multiple pulmonary emboli were the major clinical manifestations. Blood cultures were positive in 8 cases with Staphylococcus aureus as the predominant microorganism. Echocardiography detected right heart vegetations in all cases, with tricuspid valve as the structure most frequently affected. Most patients were successfully treated with antimicrobials. The outcome was favourable, with a mortality of 11.8 % . Conclusions The clinical features of RIE are different from that of left-sided infective endocarditis (LIE) . Echocardiography plays an important role in the diagnosis of RIE.

    Aim To explore the experience of governing body nurses appointed to clinical commissioning group (CCG) boards; how they perform their responsibilities; and their perceived effectiveness in ensuring safe, patient-centred care and the factors that influence their effectiveness. Method This was a small pilot study using a mixed methods approach. There were four phases of the study: literature review, qualitative data collection (interviews), quantitative data collection (survey), and final data analysis. Findings In the early stages of the formation of CCGs, few governing body nurses had relevant experience to meet the needs of a strategic role, and many of these nurses had no proper job description, too little time to carry out their responsibilities, little management support, and unequal access to training, development, formal support or supervision compared to GP colleagues. Two working patterns or models of work of governing body nurses emerged: the full-time integrated executive statutory role and the part-time non-executive statutory role. Quality and quality assurance were the most frequently cited roles or responsibilities of governing body nurses in CCGs, and their highest priority was to improve the population's health. Conclusion The role of governing body nurse has emerged at a time of organisational change, and following extensive criticism of nursing and nurses in the media. Nurses' roles and experiences are affected by these contextual events and by the emerging structures and diversity of CCGs. Further research is required into the leadership role of governing body nurses, succession planning, and the effectiveness of their relationships with other senior nurses. PMID:27305258

    Differentiation of infectious causes in severely ill children is essential but challenging in sub- Saharan Africa. The aim of the study was to determine clinical indicators that are able to identify bacterial co-infections in P. falciparum infected children in rural Ghana. In total, 1,915 severely ill children below the age of 15 years were recruited at Agogo Presbyterian Hospital in Ghana between May 2007 and February 2011. In 771 (40%) of the children malaria parasites were detected. This group was analyzed for indicators of bacterial co-infections using bivariate and multivariate regression analyses with 24 socio-economic variables, 16 terms describing medical history and anthropometrical information and 68 variables describing clinical symptoms. The variables were tested for sensitivity, specificity, positive predictive value and negative predictive value. In 46 (6.0%) of the children with malaria infection, bacterial co-infection was detected. The most frequent pathogens were non-typhoid salmonellae (45.7%), followed by Streptococcus spp. (13.0%). Coughing, dehydration, splenomegaly, severe anemia and leukocytosis were positively associated with bacteremia. Domestic hygiene and exclusive breastfeeding is negatively associated with bacteremia. In cases of high parasitemia (>10,000/μl), a significant association with bacteremia was found for splenomegaly (OR 8.8; CI 1.6-48.9), dehydration (OR 18.2; CI 2.0-166.0) and coughing (OR 9.0; CI 0.7-118.6). In children with low parasitemia, associations with bacteremia were found for vomiting (OR 4.7; CI 1.4-15.8), severe anemia (OR 3.3; CI 1.0-11.1) and leukocytosis (OR 6.8 CI 1.9-24.2). Clinical signs of impaired microcirculation were negatively associated with bacteremia. Ceftriaxone achieved best coverage of isolated pathogens. The results demonstrate the limitation of clinical symptoms to determine bacterial co-infections in P. falciparum infected children. Best clinical indicators are dependent on the parasitemia

    Scrub typhus infection is an important cause of acute undifferentiated fever in South East Asia. The clinical picture is characterized by sudden onset fever with chills and non-specific symptoms that include headache, myalgia, sweating and vomiting. The presence of an eschar, in about half the patients with proven scrub typhus infection and usually seen in the axilla, groin or inguinal region, is characteristic of scrub typhus. Common laboratory findings are elevated liver transaminases, thrombocytopenia and leukocytosis. About a third of patients admitted to hospital with scrub typhus infection have evidence of organ dysfunction that may include respiratory failure, circulatory shock, mild renal or hepatic dysfunction, central nervous system involvement or hematological abnormalities. Since the symptoms and signs are non-specific and resemble other tropical infections like malaria, enteric fever, dengue or leptospirosis, appropriate laboratory tests are necessary to confirm diagnosis. Serological assays are the mainstay of diagnosis as they are easy to perform; the reference test is the indirect immunofluorescence assay (IFA) for the detection of IgM antibodies. However in clinical practice, the enzyme-linked immuno-sorbent assay is done due to the ease of performing this test and a good sensitivity and sensitivity when compared with the IFA. Paired samples, obtained at least two weeks apart, demonstrating a ≥ 4 fold rise in titre, is necessary for confirmation of serologic diagnosis. The mainstay of treatment is the tetracycline group of antibiotics or chloramphenicol although macrolides are used alternatively. In mild cases, recovery is complete. In severe cases with multi-organ failure, mortality may be as high as 24%. PMID:26261776

    Abstract Acinetobacter baumannii is one of the most important antibiotic-resistant nosocomial bacteria. We investigated changes in the clinical and molecular epidemiology of A. baumannii over a 10-year period. We compared the data from 2 prospective multicenter cohort studies in Spain, one performed in 2000 (183 patients) and one in 2010 (246 patients), which included consecutive patients infected or colonized by A. baumannii. Molecular typing was performed by repetitive extragenic palindromic polymerase chain reaction (REP-PCR), pulsed-field gel electrophoresis (PFGE), and multilocus sequence typing (MLST). The incidence density of A. baumannii colonization or infection increased significantly from 0.14 in 2000 to 0.52 in 2010 in medical services (p < 0.001). The number of non-nosocomial health care-associated cases increased from 1.2% to 14.2%, respectively (p < 0.001). Previous exposure to carbapenems increased in 2010 (16.9% in 2000 vs 27.3% in 2010, p = 0.03). The drugs most frequently used for definitive treatment of patients with infections were carbapenems in 2000 (45%) and colistin in 2010 (50.3%). There was molecular-typing evidence of an increase in the frequency of A. baumannii acquisition in non-intensive care unit wards in 2010 (7.6% in 2000 vs 19.2% in 2010, p = 0.01). By MSLT, the ST2 clonal group predominated and increased in 2010. This epidemic clonal group was more frequently resistant to imipenem and was associated with an increased risk of sepsis, although not with severe sepsis or mortality. Some significant changes were noted in the epidemiology of A. baumannii, which is increasingly affecting patients admitted to conventional wards and is also the cause of non-nosocomial health care-associated infections. Epidemic clones seem to combine antimicrobial resistance and the ability to spread, while maintaining their clinical virulence. PMID:25181313

    Full Text Available Purpose: Enterovirus 71, one of the enteroviruses that are responsible for both hand-foot-and-mouth disease and herpangina, can cause neural injury. During periods of endemic spread of hand-foot-andmouth disease caused by enterovirus 71, CNS infections are also frequently diagnosed and may lead to increased complications from neural injury, as well as death. We present the results of our epidemiologic research on the clinical manifestations of children with CNS infections caused by enterovirus 71. Methods: The study group consisted of 42 patients admitted for CNS infection by enterovirus 71 between April 2009 and October 2009 at the Department of Pediatrics of 5 major hospitals affiliated with the Catholic University of Korea. We retrospectively reviewed initial symptoms and laboratory findings on admission, the specimen from which enterovirus 71 was isolated, fever duration, admission period, treatment and progress, and complications. We compared aseptic meningitis patients with encephalitis patients. Results: Of the 42 patients (23 men, 19 women, hand-foot-and-mouth disease was most prevalent (n=39, followed by herpangina (n=3, upon initial clinical diagnosis. Among the 42 patients, 15 (35.7% were classified as severe, while 27 (64.3% were classified as mild. Factors such as age, fever duration, presence of seizure, and use of intravenous immunoglobulin (IVIG were statistically different between the 2 groups. Conclusion: Our results indicate that patients with severe infection caused by enterovirus 71 tended to be less than 3 years old, presented with at least 3 days of fever as well as seizure activity, and received IVIG treatment.

  10. [Nitrofurantoin--clinical relevance in uncomplicated urinary tract infections].

    2014-07-01

    The nitrofuran derivative nitrofurantoin has been used for more than 60 years for the antibacterial therapy of uncomplicated urinary tract infections (UTI). Despite its long application, this antibiotic retained good activity against Escherichia coli and some other pathogens of uncomplicated urinary tract infections such as Staphylococcus saprophyticus and Enterococcus species. Nitrofurantoin therapy has been shown to be accompanied by numerous adverse drug effects. Among these, there are also serious side effects such as pulmonary reactions and polyneuropathy, which mainly occur in long-term use. Recent studies, however, have shown a good efficacy and tolerability of short-term nitrofurantoin therapy comparable to previous established standard therapeutic regimens applying cotrimoxazole or quinolones. Because of these data and the alarming resistance rates of uropathogenic Escherichia coli to cotrimoxazole and quinolones that have been increased markedly in several countries, the clinical significance ofnitrofurantoin has been raised again. In many current treatment guidelines, e. g., the international clinical practice guidelines for the treatment of acute uncomplicated cystitis and pyelonephritis in women published by the Infectious Diseases Society of America and the European Society for Microbiology and Infectious Diseases, nitrofurantoin has been recommended as one first-line antibiotic of empiric antibacterial treatment of uncomplicated cystitis in otherwise healthy women. In Germany, however, nitrofurantoin should only be applied if more effective and less risky antibiotics cannot be used. Nitrofurantoin is contraindicated in the last three months of pregnancy and in patients suffering from renal impairment of each degree. Despite compatibility concerns, nitrofurantoin has also been recommended for the re-infection prophylaxis of recurrent uncomplicated urinary tract infections in Germany and several other countries.

  11. Decontamination and decorporation: the clinical experience

    International Nuclear Information System (INIS)

    Decontamination and decorporation are quite interrelated when dealing with a contaminated person. Some clinical experiences from a transuranium production facility are offered. Skin decontamination is accomplished by washing with detergent and water. Stubborn cases are treated with sodium hypochlorite followed by rinsing, and emery cloth is used on more stubborn nail or finger pad contamination. If inhaled, the usual skin cleansing followed by nasal douche with normal saline decontaminates reachable areas and one of the DTPA salts given via aerosol both decontaminates and decorporates the inner recesses. Saline laxative reduces the time inhaled, and ingested particles remain in the gastro-intestinal tract. Conservatism prevails in general, but most persons found to have inhaled contamination are given a single chelation within the hour of discovery and if subsequently found to have over 10% M.P.P.B. of a soluble actinide are offered further chelation. Single dose chelation has been found to be relatively innocuous and usually sufficient. The longest case of chelation therapy spanned 2-1/4 years and encompassed 123 doses of CaNa-DTPA

    Full Text Available OBJECTIVE: To analyze the initial clinical experience of transmyocardial laser revascularization (TMLR in patients with severe diffuse coronary artery disease. METHODS: Between February, 1998 and February, 1999, 20 patients were submitted to TMLR at the Heart Institute (InCor, University of São Paulo Medical School, Brazil, isolated or in association with conventional coronary artery bypass graft (CABG. All patients had severe diffuse coronary artery disease, with angina functional class III/IV (Canadian Cardiovascular Society score unresponsive to medical therapy. Fourteen patients were submitted to TMLR as the sole therapy, whereas 6 underwent concomitant CABG. Fifty per cent of the patients had either been previously submitted to a CABG or to a percutaneous transluminal coronary angioplasty (PTCA. Mean age was 60 years, ranging from 45 to 74 years. RESULTS: All patients had three-vessel disease, with normal or mildly impaired left ventricular global function. Follow-up ranged from 1 to 13 months (mean 6.6 months, with no postoperative short or long term mortality. There was significant symptom improvement after the procedure, with 85% of the patients free of angina, and the remaining 15 % of the patients showing improvement in functional class, as well as in exercise tolerance. CONCLUSION: This novel technique can be considered a low risk alternative for a highly selected group of patients not suitable for conventional revascularization procedures.

  14. Analysis of clinical features and risk factors for infective endocarditis

    International Nuclear Information System (INIS)

    Objective: To analyze the clinical features of infective endocarditis (IE) and explore the risk factors for it's prognosis. Methods: Clinical data of 65 patients with IE were acquired retrospectively, and its causes, clinical characteristics, pathogenic microorganism, clinical outcomes were analyzed. Results: The major occurring heart diseases for IE in all patients were rheumatic heart disease, congenital heart disease, and there was no any previously known heart disease. The major clinical manifestations included fever and anemia. The major pathogenic bacteria is streptococcus, but percentage of other bacteria increased gradually. Thirteen patients were refractory, in hospital. Haematoglobin and seralbumin were significantly lower, and leucocyte, hsCRP, erythrocyte sedimentation were significantly higher in refractory group. Anaemia, lower seralbumin, higher hsCRP were independent predictors for bad prognosis. Conclusion: The proportion of rheumatic heart disease is decreasing as one of the risk factors for IE in recent years. Streptococcus is major pathogen of IE, and the mortality of IE is still very high. Anaemia, lower seralbumin, higher hsCRP are independent predictors for bad prognosis. (authors)

    Full Text Available Experimental infection was done on 13 dogs, with B. burgdorferi s.l., in the epitzootiological area where Lyme disease in dogs and humans is present. Prior to the experimental infection, dogs in the experiment had no contact with B. burgdorferi, and they were kept in isolation. Serological methods used in the study were complement fixation and ELISA test. Biochemical blood analysis was done, also. The experimental infection of dogs was done with a referent ATCC B. burgdorferi s.l. culture, and with the isolates of B. burgdorferi s.l. previousely gained from Ixodes ricinus ticks collected on selected locations of the observed region in the northern part of Serbia (Vojvodina province. After the experimental infection, clinical symptoms were not seen in dogs and positive serological results were found in 70% of experimentally infected dogs. Immunodiagnostic criteria for the diagnosis of Lyme disease in dogs are established. In dogs without clinical symptoms for Lyme disease, when clarifying the laboratory results, one must have in mind the epizootiological situation of the region and also the possibility of former contact of the dog with B. burgdorferi s.l. For epizootiological surveys, CF can be used as an approximate screening method, with obligatory conformation with ELISA in the case of positive findings.

    2014-02-01

    Full Text Available Since the emergence of West Nile virus (WNV in North America in 1999, understanding of the clinical features, spectrum of illness and eventual functional outcomes of human illness has increased tremendously. Most human infections with WNV remain clinically silent. Among those persons developing symptomatic illness, most develop a self-limited febrile illness. More severe illness with WNV (West Nile neuroinvasive disease, WNND is manifested as meningitis, encephalitis or an acute anterior (polio myelitis. These manifestations are generally more prevalent in older persons or those with immunosuppression. In the future, a more thorough understanding of the long-term physical, cognitive and functional outcomes of persons recovering from WNV illness will be important in understanding the overall illness burden.

Methods: We reviewed following data for all patients: age, gender, accompanied diseases, clinical types, localization and treatment. Superficial mycotic infections were diagnosed on the basis of clinical picture, direct microscopy and some of them were confirmed by fungal cultures. Results: Our patients comprised 33 boys (64.7% and 18 girls (35.3%, with an average age of 6.2 years (range 4 months to 17 years. Eighteen patients (35.3% had dermatophytes on the scalp. Clinical forms, in the order of frequency, were: tinea capitis profunda in 10 patients (19.6%, tinea capitis superficialis in 8 patients (15.8%, tinea unguium in 8 patients (15.8%. Tinea capitis (35.3% was the most frequent form of dermatomycosis. The most common symptom was the pruritus. Thirty (58% patients were treated with local antimycotics and 21 (42% patients were treated with systemic terbinafine or itraconazole. Conclusion: In this study it was found that, tinea capitis was the most frequent form of dermatomycosis and onychomycosis in children are not uncommon as it is mentioned. The data also suggest that topical antifungal agents may be effective and well-tolerated in the treatment of onychomycosis and tinea capitis in children.

  2. Overwhelming postsplenectomy infection syndrome in adults - A clinically preventable disease

    2008-01-01

    Overwhelming postsplenectomy infection (OPSI)syndrome is a rare condition, but is associated with high mortality. However, recognition and clinical management of OPSI is not well established. The prevalence of splenectomy increased recently because it was a clinically effective treatment for hepatitis C virus-associated thrombocytopenia before the introduction of the interferon/ribavirin combination therapy. We reviewed the literature characterizing the clinicopathological features of OPSI and assessed the most effective and feasible administration of the condition. A Medline search was performed using the keywords 'overwhelming','postsplenectomy infection', 'postsplenectomy sepsis','chronic liver disease', and/or 'splenectomy'. Additional articles were obtained from references within the papers identified by the Medilne search. Durations between splenectomy and onset of OPSI ranged from less than 1 wk to more than 20 years. Autopsy showed that many patients with OPSI also had Waterhouse-Friderichsen syndrome. Although the mortality rate from OPSI has been reduced by appropriate vaccination and education,the precise pathogenesis and a suitable therapeutic strategy remain to be elucidated. Protein energy malnutrition (PEM) is commonly observed in cirrhotic patients. Since the immune response in patients with PEM is compromised, a more careful management for OPSI should therefore be applied for cirrhotic patients after splenectomy. In addition, strict long-term follow up of OPST patients including informed consent will lead to a better prognosis.

    Our knowledge of warts dates thousands of years. Most warts represent no more than a transient infection in the hands and feet of children and adults. With the relatively recent medical advances permitting the prolonged survival of immunocompromised hosts, however, HPV-induced lesions have become an important problem. In these patients, lesions represent a recurring, intractable infection that predisposes the patient to the development of skin cancer. Such problems have been appreciated for some time in patients with EV. Newer laboratory techniques have led to an increasing number of clinical entities linked with an HPV cause in the nonimmunosuppressed host. Although evidence incriminating HPV as a causative factor for genital cancers of the cervix and the skin continues to mount, such evidence for nongenital Bowen's disease, certain squamous cell carcinomas of the skin, keratoacanthomas, and other tumors of the skin also has begun to grow. It is to be hoped that continued advances in molecular biologic techniques will further delineate the relationship between HPV and these conditions, lead to an HPV classification scheme that is more utilitarian from a clinical point of view, and ultimately lead to improved treatment.

    Full Text Available Context: Skin changes in pregnancy can be categorized as 1 physiological/hormonal, 2 alterations in pre-existing skin diseases, or 3 represent development of new dermatoses, some of which may be pregnancy specific. Case Report: We describe a 19 years old female at 27 weeks gestation who presented with a rash on the face and breast, with intense pruritis. Hematoxylin and eosin demonstrated Scabies mites within the epidermis, with an intense perivascular infiltrate of lymphohistiocytic cells around the superficial dermal blood vessels. By direct immunofluorescence (DIF, human fibrinogen was also detected in the perivascular areas. DIF also revealed deposits of human IgG and complement C5-9/MAC deposits in the sweat glands, as well as in nerves surrounding the sweat glands subjacent to the mites. Overexpression of ezrin and junctional adhesion molecule antibodies close to the scabies infection sites were also seen. Conclusion: Given that the hallmark of clinical scabies is intense pruritus and that very limited information is available regarding the pathophysiology of this symptom, we suggest that the itching sensation may be exacerbated by nerves and eccrine sweat glands in close proximity to the sites of infection.

  11. Clinical development of microbicides for the prevention of HIV infection.

    D'Cruz, Osmond J; Uckun, Fatih M

    2004-01-01

    The HIV/AIDS pandemic continues its spread at a rate of over 15,000 new infections every day. Sexual transmission of HIV-1 is the dominant mode of this pandemic spread. For the first time since the disease emerged in the early 1980s, about half the 42 million people now living with HIV/AIDS worldwide are women. Worldwide, more than 90 percent of all adolescent and adult HIV infections have resulted from heterosexual intercourse. The "feminization" of the pandemic largely driven by the social, economic, and biological factors warrants urgent attention particularly for the adolescent female population. In the absence of an effective prophylactic anti-HIV therapy or vaccine, current efforts are aimed at developing intravaginal/intrarectal topical formulations of anti-HIV agents or microbicides to curb the mucosal and perinatal HIV transmission. Microbicides would provide protection by directly inactivating HIV or preventing HIV from attaching, entering or replicating in susceptible target cells as well as dissemination from target cells present in semen or the host cells that line the vaginal/rectal wall. Thus, ideally, anti-HIV microbicides should be capable of attacking HIV from different angles. In addition, a contraceptive microbicide could help prevent unintended pregnancies worldwide. To be a microbicide, these agents must be safe, effective following vaginal or rectal administration, and should cause minimal or no genital symptoms following long-term repeated usage. A safe and efficacious anti-HIV microbicide is not yet available despite the fact that more than 60 candidate agents have been identified to have in vitro activity against HIV, 18 of which have advanced to clinical testing. Targeting HIV entry has been a favored approach because it is the first step in the process of infection and several readily available anionic polymeric products seem to variably interfere with these processes are the primary candidates for potential microbicides.

    This review considers the detection and management of early HIV infection (EHI), defined here as the first 6 months of infection. This phase is clinically important because a reservoir of infected cells formed in the individual renders HIV incurable, and the magnitude of viremia at the end of this period predicts the natural history of disease. Epidemiologically, it is critical because the very high viral load that typically accompanies early infection also makes infected individuals maximall...

    Full Text Available Nasopharyngeal tuberculosis (NPTB is a noteworthy disease especially in its worldwide spread of the Mycobacterium infection. Although NPTB has been identified in less than one percent of TB cases, recent multiple case reports indicate an either increased awareness or incidence of this disease. The most helpful diagnostic tool is an uncomplicated nasopharyngeal biopsy. However, NPTB is usually ignored because it has varied clinical manifestations and similar presentations with other more common head and neck diseases. Furthermore, the most common presenting symptom is cervical lymphadenopathy mimicking nasopharyngeal carcinoma, a more common and serious disease. Treatment outcomes of NPTB are good in both HIV-positive or HIV-negative patients. In addition, pulmonary tuberculosis association was reported in wide range between 8.3% and 82% which should be considered in a treatment program. In conclusion, early diagnosis and management in NPTB can be achieved by (1 increased awareness of this disease, (2 improvement in knowledge regarding clinical manifestations, and (3 improvement of diagnostic techniques.

    2011-09-01

    Full Text Available Abstract There is currently much interest in adult mesenchymal stem cells (MSCs and their ability to differentiate into other cell types, and to partake in the anatomy and physiology of remote organs. It is now clear these cells may be purified from several organs in the body besides bone marrow. MSCs take part in wound healing by contributing to myofibroblast and possibly fibroblast populations, and may be involved in epithelial tissue regeneration in certain organs, although this remains more controversial. In this review, we examine the ability of MSCs to modulate liver, kidney, heart and intestinal repair, and we update their opposing qualities of being less immunogenic and therefore tolerated in a transplant situation, yet being able to contribute to xenograft models of human tumour formation in other contexts. However, such observations have not been replicated in the clinic. Recent studies showing the clinical safety of MSC in several pathologies are discussed. The possible opposing powers of MSC need careful understanding and control if their clinical potential is to be realised with long-term safety for patients.

    Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality. PMID:25589093

    2011-01-01

    Full Text Available Introduction. Non-immune hydrops fetalis is a condition of excessive accumulation of extravascular fluid without identifiable circulating antibody to erythrocytes membrane antigens. In newborn infants it is characterized by skin oedema and pleural, pericardial or peritoneal effusion. In the era of routine Rh immunization for the prevention of foetal erythroblastosis, non-immune pathophysiologic mechanisms are presented in 76-87% of all hydropic newborns. Non-immune hydrops fetalis can be associated with numerous and various disorders. The mortality rate may exceed 50%. This study was aimed at presenting our clinical experience in treating newborn infants with non-immune hydrops fetalis. Material and methods. A retrospective-prospective study included newborn infants with non-immune hydrops fetalis, who were treated in the Neonatal Intensive Care Unit of Mother and Child Health Institute of Serbia between January 1, 2001 and October 31, 2010. All valid data about aetiology, diagnosis, clinical course and outcome were recorded. Results. The diagnosis of non-immune hydrops fetalis was made in 11 newborns. The etiologic diagnosis was established in 8 patients: anaemia due to fetomaternal transfusion in 4 patients and conatal cytomegalovirus infection, intracranial haemorrhage, isolated pulmonary lymphangiectasia and diffuse skin and mediastinal lymphangiomatosis in the remaining 4 patients. Conclusion. Non-immune hydrops of newborn infant is associated with a high mortality rate and requires complex diagnostic and therapeutic procedures. An optimal management of neonates with non-immune hydrops fetalis demands a multidisciplinary approach to the treatment in a neonatal intensive care unit.

    Full Text Available Results from cohort studies evaluating the severity of respiratory viral co-infections are conflicting. We conducted a systematic review and meta-analysis to assess the clinical severity of viral co-infections as compared to single viral respiratory infections.We searched electronic databases and other sources for studies published up to January 28, 2013. We included observational studies on inpatients with respiratory illnesses comparing the clinical severity of viral co-infections to single viral infections as detected by molecular assays. The primary outcome reflecting clinical disease severity was length of hospital stay (LOS. A random-effects model was used to conduct the meta-analyses.Twenty-one studies involving 4,280 patients were included. The overall quality of evidence applying the GRADE approach ranged from moderate for oxygen requirements to low for all other outcomes. No significant differences in length of hospital stay (LOS (mean difference (MD -0.20 days, 95% CI -0.94, 0.53, p = 0.59, or mortality (RR 2.44, 95% CI 0.86, 6.91, p = 0.09 were documented in subjects with viral co-infections compared to those with a single viral infection. There was no evidence for differences in effects across age subgroups in post hoc analyses with the exception of the higher mortality in preschool children (RR 9.82, 95% CI 3.09, 31.20, p<0.001 with viral co-infection as compared to other age groups (I2 for subgroup analysis 64%, p = 0.04.No differences in clinical disease severity between viral co-infections and single respiratory infections were documented. The suggested increased risk of mortality observed amongst children with viral co-infections requires further investigation.

    Full Text Available Although urinary tract infections (UTI represent the most common infection caused by enterococci, some aspects remain to be fully clarified. The aim of this study was to determine the clinical characteristics present in UTI caused by Enterococcus spp. in patients followed up at the Prof. Edgard Santos Teaching Hospital of the Federal University of Bahia. All patients consecutively examined between 1997 and 2005, who received a diagnosis of UTI caused by Enterococcus spp. were included in the study. UTI was defined as the presence of 10(5 colony-forming units per mL of urine. Standard microbiological techniques were used. During the study period, 6.2% of the urine cultures were positive for Enterococcus spp. The mean age of the patients was 48.9 years and 57% were male. At initial evaluation, 13% of the patients had complaints suggestive of UTI. Nineteen patients had a history consistent with obstructive uropathy and 26 with neurogenic bladder. At final evaluation, UTI was the diagnosis in 48 patients. In 36 patients (29%, the primary diagnosis was related to urogenital diseases, consisting of obstructive uropathy in 23 of these cases, while in 32 patients (25.8% primary diagnosis was related to neurologic diseases, frequently neurogenic bladder. UTI caused by Enterococcus spp. is not infrequent, is usually associated with few or no symptoms and occurs in sick patients who have anatomical or functional obstructive uropathy associated or not with urinary tract catheterization or instrumentation. The diagnosis of enterococcal UTI may indicate a urinary tract abnormality yet to be diagnosed.

    2010-01-01

    Full Text Available The paper describes the present view of the problem of insomnia and gives a classification of sleep disorders and basic methods for their drug and non-drug therapy. Emphasis is placed on the role of the objective sleep study - polysomnography. The use of the current hypnotics belonging to a three Zs group and the minimization of administration of benzodiazepines are most important in pharmacotherapy for insomnia. The results of a clinical polysomnographic study of the effect of Zolpidem (Sanval in patients with insomnia are presented. The subjective evaluation of the beneficial effect of a 10-day course of Sanval is confirmed by the objective studies of the sleep pattern undergoing positive changes in the most important indicators, such as the process of falling asleep, the time of intrasleep awakenings, and the duration of Δ-sleep. The high safety and good tolerability of Sanval permit the latter to be assessed as an effective agent for the treatment of insomnia.

  7. [Euthanasia--experiences from Norwegian pain clinics].

    Meidell, N K; Naess, A C

    1998-10-10

    This survey focuses on the subject of euthanasia. A questionnaire was sent to 90 doctors working in pain clinics in Norwegian hospitals. 60 doctors (67%) returned the questionnaire. Only 18 doctors (30%) had ever received a request for euthanasia. The patients who requested euthanasia suffered from refractory pain, depression, fear of pain and fear of becoming helpless. 67% of the doctors were satisfied with the present Norwegian law, while 13% favoured a liberalization of the law. Only 5% were willing to comply with the patient's request for euthanasia under today's law. One third of the doctors would leave the decision to an officially appointed "board" if euthanasia were to become legalized. A majority wanted a doctor to commit the actual procedure, but there were also suggestions that a lawyer or other lay person should carry out the act of euthanasia. Our conclusion is that the closer the patient-doctor relationship is, the more opposed the doctor is to euthanasia. PMID:9816949

    Target: In 1989 in the Kantonal Hospital of Lucerne conventional film-screen mammography was replaced by digital mammography. With the support of a retrospective study, it was checked whether or not digital mammography represents an equally valid diagnostic procedure in daily routine. Methods: 1204 patients were examined using digital mammography. A reevaluation of these patients was carried out using clinical and r[iological routine controls. [ditionally a r[iological and histological examination was performed in 127 cases in which excisional biopsies h[ been done, paying particular attention to detail perception. Results: The sensitivity of digital mammography achieved a total of 85%, whereas the accuracy was 81%. With [ditional use of ultrasound and galactography the sensitivity attained 91%. By reevaluation the sensitivity amounted to 87%, the accuracy remaining at 81%. The positive predictive value was especially high with 76% and 77%. Conclusion: Digital mammography offers satisfactory diagnostic performance. (orig.)

  11. Deep-neck infection. Clinical analysis of 299 cases

    International Nuclear Information System (INIS)

    Deep-neck infection (DNI) remains potentially fatal. We retrospectively analyzed 299 surgically treated DNI cases between January 1997 and October 2007 by reviewing computed tomography (CT) results and discuss treatment and risk factors. Subjects were divided into two groups by abscess-site; peritonsillar abscess (PTA) (n=251) and deep-neck abscess (DNA) (n=48). Age, smoking habits, body mass index (BMI) and bacteriological histories were collected from clinical records and compared by group. DNI and PTA severity parameters were C-reactive protein (CRP) titer and hospitalization length. Median subject age in DNI was 51.0 years and peak incidence in the 50 s. Median subject age in PTA was 31.0 years and the peak incidence in the 20 s. Smoker prevalence was higher in both groups than in normal healthy subjects. The DNI group had higher BMI and diabetes mellitus. Factors potentially most affecting illness were complications such as obesity and diabetes mellitus in DNI and age in PTA. (author)

  12. Cartap hydrochloride poisoning: A clinical experience

    Directory of Open Access Journals (Sweden)

    Hari K Boorugu

    2012-01-01

    Full Text Available Cartap hydrochloride, a nereistoxin analog, is a commonly used low toxicity insecticide. We describe a patient who presented to the emergency department with alleged history of ingestion of Cartap hydrochloride as an act of deliberate self-harm. The patient was managed conservatively. To our knowledge this is the first case report of Cartap hydrochloride suicidal poisoning. Cartap toxicity has been considered to be minimal, but a number of animal models have shown significant neuromuscular toxicity resulting in respiratory failure. It is hypothesized that the primary effect of Cartap hydrochloride is through inhibition of the [ 3 H]-ryanodine binding to the Ca 2+ release channel in the sarcoplasmic reticulum in a dose-dependent manner and promotion of extracellular Ca 2+ influx and induction of internal Ca 2+ release. This results in tonic diaphragmatic contraction rather than paralysis. This is the basis of the clinical presentation of acute Cartap poisoning as well as the treatment with chelators namely British Anti Lewisite and sodium dimercaptopropane sulfonate.

  13. Epidemiology, clinical impacts and current clinical management of Helicobacter pylori infection.

    2016-06-01

    Helicobacter pylori infection is a major cause of morbidity and mortality worldwide. More than 50% of the global population is estimated to be infected. Differences in prevalence exist within and between countries, with higher prevalence seen among people with lower socio-economic status. Most transmission of infection occurs early in life, predominantly from person to person in the family setting. H. pylori is the cause of most peptic ulcer disease, gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and causes symptoms in a subset of patients with functional dyspepsia. Choice of diagnostic test depends on the clinical context; urea breath tests and endoscopy with biopsy are the major diagnostic tools. Evidence-based indications for eradication of H. pylori infection are well documented. The most widely used and recommended eradication therapy in Australia is triple therapy comprising a proton pump inhibitor, amoxycillin and clarithromycin, usually for 1 week. Effective alternative regimens are available for patients with proven allergy to penicillin. Antimicrobial resistance is the major determinant of the outcome of eradication therapy. Trends in antibiotic resistance need to be monitored locally, but individual patient susceptibility testing is not usually necessary as it rarely guides the choice of therapy. The outcome of treatment should be assessed not less than 4 weeks after therapy. This is usually done with a urea breath test if follow-up endoscopy is not required. When first-line therapy fails, several proven second-line therapies may be used. Repeat first-line therapy and ad hoc regimens should be avoided. Overall cumulative eradication rates should approach 99%. PMID:27256648

    AIM: To evaluate the clinic features of eosinophilicgastroenteritis and to examine the diagnosis, treatment,long-term outcome of this disease.METHODS: Charts with a diagnosis of eosinophilicgastroenteritis from 1984 to 2002 at Mackay Memorial Hospital were reviewed retrospectively. There were 15 patients diagnosed with eosinophilic gastroenteritis. The diagnosis was established in 13 by histologic evaluation of endoscopic biopsy or operative specimen and in 2 by radiologic imaging and the presence of eosinophilic ascites.RESULTS: All the patients had gastrointestinal symptoms and 12 (80 %) had hypereosinophilia (absolute eosinophil count 1 008 to 31 360/cm3). The most common symptoms were abdominal pain and diarrhea. Five of the 15 patients had a history of allergy. Seven patients had involvement of the mucosa, 2 of muscularis, and 6 of subserosa. One with a history of seafood allergy was successfully treated with an elimination diet. Another patient improved spontaneously after fasted for several days. The remaining 13 patients were treated with oral prednisolone, 10 to 40 mg/day initially,which was then tapered. The symptoms in all the patients subsided within two weeks. Eleven of the 15 patients were followed up for more than 12 months (12 to 104 months,mean 48.7), of whom 5 had relapses after discontinuing steroids (13 episodes). Two of these patients required longterm maintenance oral prednisolone (5 to 10 mg/day).CONCLUSION: Eosinophilic gastroenteritis is a rare condition of unclear etiology characterized by relapses and remissions. Short courses of corticosteroids are the mainstay of treatment, although some patients with relapsing disease require long-term low-dose steroids.

    Full Text Available Introduction: In this environment, previous workers have reported on the challenges of managing large sized ameloblastoma of the jaws with less than adequate facilities. The aim of this review is to present the management of 68 cases of ameloblastoma with emphasis on surgical care. Materials and Methods: Retrospective survey of case notes of patients with histopathologic diagnosis of ameloblastoma (using the criteria of Barnes et al., 2005 seen between January 2006 and August 2010 at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria was undertaken. Data collected includes histopathological diagnosis, age, gender, clinical information on site of lesion, form of intubation and surgical procedure performed. Results: Out of 94 patients, 68 with histological diagnosis of ameloblastoma (59 mandibular and 9 maxillary were operated within the study period. The remainder (26 was not treated in hospital. Among 68 patients treated, more were males (38 than females (30, giving a male to female ratio of 1.3:1. The age range was between 14 and 74 years (mean-standard deviation. The duration of the symptoms ranged from 7 months to 24 years, most were follicular ameloblastoma (n = 13 followed by acanthomatous type (n = 7. Endotracheal intubation was the most common (n = 55 followed by fiber optic laryngoscopy (n = 8. The surgical approach most used was extended Risdon with intraoral (n = 24 followed by extended Risdon with lip split and intraoral (n = 17. Segmental resection (en block formed the bulk of our procedures (n = 22 followed by subtotal mandibulectomy (n = 16. Conclusion: The treatment of ameloblastoma remains controversial. Its destructive nature has left patients with wide defects difficult to reconstruct.

  3. Clinical data and CT findings of pulmonary infection caused by different pathogens after kidney transplantation

    International Nuclear Information System (INIS)

    Purpose: The overall objective was to review clinical data and CT findings of pulmonary infection caused by different pathogens after kidney transplantation in an attempt to help early clinical qualitative diagnosis. Materials and methods: 446 cases of clinically confirmed pulmonary infection after kidney transplantation in recent 10 years were evaluated with respect to the time of occurrence and 89 cases with complete CT data and pathogenic diagnosis were further analyzed for pathogen types and CT manifestations. Statistical analysis was performed using Fisher's exact test. Results: Pulmonary infection reached the peak in 3 months after transplantation. Bacterial infection and mixed infection were predominant between 1 and 6 months. And most tuberculosis occurred after one year. Bacterial (38.2%) and mixed infections (38.2%) were the common types. The next was fungal infection, tuberculosis and viral infection (10.1%, 7.9% and 5.6%, respectively). CT manifestations of pulmonary infections after kidney transplantation were diverse and complex, lacking characteristic signs. Conclusion: More than 3/4 of pulmonary infections after kidney transplantation can be attributed to bacteria and mixed pathogens. The combination of time course, clinical data and CT manifestations plays an important role in the early clinical qualitative diagnosis.

    Ankle fractures are very common, and although algorithms are in place for osseous management, consensus has not been reached regarding treatment of associated ligamentous injuries. Although tibiofibular syndesmotic stabilization can be done using different forms of fixation, the biomedical literature has long emphasized the risk of long-term restriction of ankle mobility with the use of lagged transfixation. However, when reduction cannot be maintained with positional fixation, we found that lagging the syndesmotic screw helped to maintain the reduction without causing functional restriction. In this report, we describe our experience with patients who had undergone lagged tibiofibular transfixation and were available for short- to intermediate-term follow-up to assess ankle function. A total of 31 patients (32.63% of 95 consecutive patients) were available at a mean of 34.87 (range 18 to 52) months to complete the American Orthopedic Foot and Ankle Society ankle-hindfoot questionnaire. The mean score was 88.38 (range 42 to 100) points at a mean follow-up interval of 34.87 (range 18 to 52) months. Of 31 patients, 19 had an AOFAS score of 90 points, 9 an AOFAS score of 80 to 89 points, 2 an AOFAS score of 60 to 69 points, and 1 an AOFAS score of ankle kinematics than positional syndesmotic fixation.

    In this article, we present a case study of residents' clinical experiences and communication in outpatient oncology consultations. We apply positioning theory, a dynamic alternative to role theory, to investigate how oncology residents and patients situate themselves as persons with rights and duties. Drawing from seven qualitative interviews and six days of observation, we investigate the residents' social positioning and their conversations with patients or supervisors. Our focus is on how (a) relational shifts in authority depend on each situation and its participants; (b) storylines establish acts and positions and narratively frame what participants can expect from a medical consultation viewed as a social episode; and (c) the positioning of rights and duties can lead to misunderstandings and frustrations. We conclude that residents and patients locate themselves in outpatient conversations as participants who jointly produce and are produced by patients' and nurses' storylines about who should take responsibility for treatment.

    Full Text Available Enterovirus 71 (EV71 has been recognized as a frequent cause of epidemics of hand-foot-and-mouth disease (HFMD associated with severe neurological symptoms. In the spring of 2009, HFMD was epidemic in Korea. Severe cases with complication, including death, have been reported and it has become a public health issue. Most symptomatic EV71 infections commonly result in HFMD or herpangina. These clinical manifestations can be associated with neurologic syndromes frequently. Neurologic syndromes observed in EV71 include meningitis, meningoencephalomyelitis, poliomyelitis-like paralytic disease, Guillain-Barr&eacute; syndrome, transverse myelitis, cerebellar ataxia, opsoclonus-myoclonus syndrome, benign intracranial hypertension, and brainstem encephalitis. Examinations for EV 71 were performed from the stools, respiratory secretion or CSF of the children by realtime PCR. Gene analysis showed that most of them were caused by EV71 subgenotype C4a which was prevalent in China, 2008. Public health measures including personal and environmental hygiene, must to target daycare centers, kindergartens, and schools where highly susceptible children congregate. To prevent the spread of infection, preschools where transmission persists for more than 2 incubation periods, have been recommended for closure, and trigger criteria for voluntary closure was instituted. During closure, operators are to thoroughly clean the centers before they are allowed to reopen. In addition, parents are advised to ensure that their children adopt a high standard of personal hygiene and to keep the infected child at home until full recovery. Because the outbreaks occur in a cyclical pattern, surveillance system to predict next outbreaks and adequate public health measures to control need to be planned for future. Control of EV71 epidemics through surveillance and public health intervention needs to be maintained in Korea. Future research should focus on understanding of EV71

    Full Text Available Generally speaking, in pediatrics the patients mostly affected by fungal infections are hematological patients, followed by those with solid tumors, and transplant recipients. Candida infections generally occur just after birth, whereas Aspergillus infections are age-related, and increase their incidence with age. However, among infections, the incidence of bacteremias are still greater than that of mycoses. In pediatrics, in Italy the immunocompromised patients – thus particularly susceptible to fungal infections – are mainly those with severe combined immunodeficiency, chronic mucocutaneous candidiasis, and chronic granulomatous disease. Particular Aspergillus or Scedosporium infections should be considered in peculiar kinds of patients, such as those affected by cystic fibrosis. Finally, different kinds of fungi should be considered in those who come from or spend a lot time in specific areas, such as South America (e.g. coccidioidomycoses, for which differential diagnosis is with tuberculosis.http://dx.doi.org/10.7175/rhc.v4i1S.859

    Full Text Available Introduction: In Trypanosoma cruzi infection, the pathogenesis is the result of a rupture in the host - parasite relationship [1]. This rupture is related to the imbalance of the vital force of the host, expressed through signs and symptoms, defined by Hahnemann (1995[2] as being the source of the disease. There is no research in the literature about the clinical evolution of mice experimentally infected with T. cruzi and treated in different ways using biotherapic. Therefore, this is an area to be studied in the future. Aim: To evaluate the effect of different ways of treatment using biotherapic T. cruzi 17 DH on clinical evolution of mice experimentally infected with T. cruzi. Materials and methods: A blind randomized controlled trial was performed, using 30 swiss male mice, aged 28 days, divided into groups according to the treatment: CONTROL - animals treated with 7% water-alcohol solution diluted in water given ad libitum in an amber bottle; GAVAGE – animals treated with medication highly diluted T. cruzi 17 DH from 4th to 9th day of infection by gavage; WATER -animals treated with highly diluted T. cruzi 17 DH in water ad libitum offered in an amber bottle until the end of the study period. The groups were infected with the Y strain of T. cruzi, intraperitoneal, 1400 blood trypomastigotes. The medicine was handled according to the Brazilian Homeopathic Pharmacopoeia [3] with microbiological test according to RDC n° 67 and in vivo biological risk. Parasitemic curve was determined by daily counting of the parasites [4]. Were measured temperature, weight, intake of water and feed, the ruffle fur and survival of mice. Statistical analysis was performed using the tests Fisher Exact and Log-Rank, with a significance of 5%. The experiment was approved under the protocol n° 030/2008 - Ethics in Animal Experimentation of the Universidade Estadual de Maringá. Results: The mice under different

    Full Text Available Objective: Our objective was to evaluate the educational value of introducing pre-clinical medical students to pediatric patients and their families in a subspecialty clinic setting. Methods: First- and second-year medical students at the University of Michigan seeking clinical experience outside of the classroom attended an outpatient pediatric pulmonary clinic. Evaluation of the experience consisted of pre- and post-clinic student surveys and post-clinic parent surveys with statements employing a four-point Likert scale as well as open-ended questions. Results: Twenty-eight first-year students, 6 second-year students, and 33 parents participated in the study. Post-clinic statement scores significantly increased for statements addressing empathic attitudes, confidence communicating with children and families, comfort in the clinical environment, and social awareness. Scores did not change for statements addressing motivation, a sense of team membership, or confidence with career goals. Students achieved their goals of gaining experience interacting with patients, learning about pulmonary diseases, and observing clinic workflow. Parents felt that they contributed to student education and were not inconvenienced. Conclusions: Students identified several educational benefits of exposure to a single pediatric pulmonary clinic. Patients and families were not inconvenienced by the participation of a student. Additional studies are warranted to further investigate the value of this model of pre-clinical medical student exposure to subspecialty pediatrics.

    Little is known about the impact of enrollment on therapeutic clinical trials on adverse event rates. Primary objective was to describe the impact of clinical trial registration on sterile site microbiologically documented infection for children with newly diagnosed acute myeloid leukemia (AML). We conducted a multicenter cohort study that included children aged ≤18 years with de novo AML. Primary outcome was microbiologically documented sterile site infection. Infection rates were compared between those registered and not registered on clinical trials. Five hundred seventy-four children with AML were included of which 198 (34.5%) were registered on a therapeutic clinical trial. Overall, 400 (69.7%) had at least one sterile site microbiologically documented infection. In multiple regression, registration on clinical trials was independently associated with a higher risk of microbiologically documented sterile site infection [adjusted odds ratio (OR) 1.24, 95% confidence interval (CI) 1.01-1.53; p = 0.040] and viridans group streptococcal infection (OR 1.46, 95% CI 1.08-1.98; p = 0.015). Registration on trials was not associated with Gram-negative or invasive fungal infections. Children with newly diagnosed AML enrolled on clinical trials have a higher risk of microbiologically documented sterile site infection. This information may impact on supportive care practices in pediatric AML. PMID:26515793

    2016-04-01

    Small colony variants (SCVs) were first described more than 100 years ago for Staphylococcus aureus and various coagulase-negative staphylococci. Two decades ago, an association between chronic staphylococcal infections and the presence of SCVs was observed. Since then, many clinical studies and observations have been published which tie recurrent, persistent staphylococcal infections, including device-associated infections, bone and tissue infections, and airway infections of cystic fibrosis patients, to this special phenotype. By their intracellular lifestyle, SCVs exhibit so-called phenotypic (or functional) resistance beyond the classical resistance mechanisms, and they can often be retrieved from therapy-refractory courses of infection. In this review, the various clinical infections where SCVs can be expected and isolated, diagnostic procedures for optimized species confirmation, and the pathogenesis of SCVs, including defined underlying molecular mechanisms and the phenotype switch phenomenon, are presented. Moreover, relevant animal models and suggested treatment regimens, as well as the requirements for future research areas, are highlighted. PMID:26960941

    The ability of prior infection from one elephant endotheliotropic herpesvirus (EEHV) type to protect against clinical or lethal infection from others remains an important question. This report describes viremia and subsequent shedding of EEHV1B in two juvenile 4-yr-old Asian elephants within 3 wk or 2 mo following significant infections caused by the rarely seen EEHV4. High levels of EEHV1B shedding were detected in the first elephant prior to emergence of infection and viremia in the second animal. The EEHV1B virus associated with both infections was identical to the strain causing infection in two herd mates previously. High EEHV viremia correlated with leukopenia and thrombocytopenia, which was followed by leukocytosis and thrombocytosis when clinical signs started to resolve. The observations from these cases should be beneficial for helping other institutions monitor and treat elephants infected with EEHV1, the most common virus associated with lethal hemorrhagic disease.

    Full Text Available Purpose : To evaluate the significance of clinical signs and laboratory findings as predictors of renal parenchymal lesions and vesicoureteral reflux (VUR in childhood urinary tract infection (UTI. Methods : From July 2005 to July 2008, 180 patients admitted with a first febrile UTI at the Pediatric Department of Konkuk University Hospital were included in this study. The following were the clinical variables: leukocytosis, elevated C-reactive protein (CRP, positive urine nitrite, positive urine culture, and fever duration both before and after treatment. We evaluated the relationships between clinical variables and dimercaptosuccinic acid (DMSA scan and voiding cystourethrography (VCUG results. Results : VCUG was performed in 148 patients; of them, 37 (25.0% had VUR: 18 (12.2% had low-grade (I-II VUR, and 19 (10.5% had high-grade (III-V VUR. Of the 95 patients who underwent DMSA scanning, 29 (30.5% had cortical defects, of which 21 (63.6% had VUR: 10 (30.3%, low-grade (I-II VUR; and 11 (33.3%, high-grade VUR. Of the 57 patients who were normal on DMSA scan, 8 (14.0% had low-grade VUR and 6 (10.5% had high-grade VUR. The sensitivity, specificity, and positive and negative predictive values of the DMSA scan in predicting high-grade VUR were 64.7%, 69.9%, 33.3%, and 89.5%, respectively. Leukocytosis, elevated CRP, and prolonged fever (?#243;6 hours after treatment were significantly correlated with the cortical defects on DMSA scans and high-grade VUR. Conclusion : Clinical signs, including prolonged fever after treatment, elevated CRP, and leukocytosis, are positive predictors of acute pyelonephritis and high-grade VUR.

    Full Text Available The rate of diagnosis of colonization/infection of the airways with Achromobacter xylosoxidans has increased in cystic fibrosis patients, but its clinical significance is still controversial. This retrospective, case-control study aimed to evaluate the clinical impact of A. xylosoxidans colonization/infection in cystic fibrosis patients. Individuals who were chronically colonized/infected (n=10, intermittently colonized/infected (n=15, and never colonized/infected with A. xylosoxidans (n=18 were retrospectively evaluated during two periods that were 2 years apart. Demographic characteristics, clinical data, lung function, and chronic bacterial co-colonization data were evaluated. Of the total study population, 87% were pediatric patients and 65.1% were female. Individuals chronically colonized/infected with A. xylosoxidans had decreased forced expiratory volume in 1 s (51.7% in the chronic colonization/infection group vs 82.7% in the intermittent colonization/infection group vs 76% in the never colonized/infected group. Compared with the other two groups, the rate of co-colonization with methicillin-resistant Staphylococcus aureus was higher in individuals chronically colonized/infected with A. xylosoxidans (P=0.002. Changes in lung function over 2 years in the three groups were not significant, although a trend toward a greater decrease in lung function was observed in the chronically colonized/infected group. Compared with the other two groups, there was a greater number of annual hospitalizations in patients chronically colonized/infected with A. xylosoxidans (P=0.033. In cystic fibrosis patients, there was an increased frequency of A. xylosoxidans colonization/infection in children, and lung function was reduced in patients who were chronically colonized/infected with A. xylosoxidans. Additionally, there were no differences in clinical outcomes during the 2-year period, except for an increased number of hospitalizations in patients with A

    Objective To describe the frequency of systemic inflammatory response syndrome (SIRS) criteria in a cohort of patients hospitalised with purulent soft tissue infections and to determine their impact on clinical characteristics, microbiology and outcomes. Methods Retrospective cohort study of adults hospitalised at the West Haven Veteran's Hospital with purulent soft tissue infections between 1 October 2008 and 30 September 2013. Results A total of 173 patients were included with purulent soft tissue infections; 60 patients had no SIRS, 48 had one SIRS and 65 had ≥ 2 SIRS. Most clinical characteristics were similar between the different SIRS groups, although patients with SIRS were more likely to have severe sepsis and acute kidney injury and to already be on antibiotics at the time of hospitalisation. The microbiology of the infections was similar between SIRS groups. All patients received parenteral antibiotics when admitted and the majority of patients in all SIRS categories received antibiotics with broad Gram-negative activity. Outcomes were generally benign for all SIRS groups, although patients with SIRS had a longer length of stay and a trend towards more bacteremia. Conclusions SIRS are common in patients hospitalised with purulent soft tissue infections, although one third had no systemic signs of infection. Severe sepsis and septic shock are rare. Clinical characteristics, microbiology and antibiotic use are similar among patients in different SIRS groups, although the group without SIRS had a shorter hospitalisation and no episodes of bacteremia. Over-use of antibiotics is common in all SIRS categories. PMID:26950290

    Full Text Available At the beginning of etiopathogenic research on chicken anaemia virus (CAV it was thought that groups of chickens at risk for CAV infection were those coming from a parental flock infected before laying. Therefore it is important to know the level and persistence of transfered maternal antibodies (MaAt and to measure specific antibody development during rearing. The goal of this research was to assess the necessity for prophylactic measures by determining the humoral immune response to CAV and any clinical changes in breeder chickens. Chickens from the parental Hybro flock were examined from the first day until the end of production. Maternal antibodies for CAV, which were present initially, were not detected at 4 weeks old. At 6 weeks old specific antibodies for CAV were found in 45% of the serum samples. These antibodies increased until the 18th week when the experiment was terminated. The state of health of the parental flock in the period when MaAt antibodies could not be detected and until specific antibodies appeared did not differ significantly. The results of these investigations are the first evidence of CAV infection in Yugoslavia, based on serological examination.

    We describe our experience with stent-graft placement in a patient with a clinically diagnosed syphilitic aortic aneurysm.The patient was a 43-year-old man with syphilitic and human immunodeficiency virus (HIV) co-infection. Computed tomography (CT) revealed an aortic aneurysm with 89 mm in maximum size which was located at distal aortic arch and was considered syphilis derived saccular aneurysm. The aneurysm was judged at high risk of rupture from its shape. We decided to perform stent-graft implantation. Before surgery, the patient was given antibacterial and anti-HIV agents. Hand-made fenestrated stent graft by Tokyo Medical University was implanted. The graft was placed from the ascending aorta to Th 9 level in the descending aorta. The aneurysm completely disappeared during follow-up, with no flare-up of syphilitic infection up to 2 years after surgery.The number of patients with syphilis and human immunodeficiency virus co-infection is now increasing. Stent-graft implantation may be an effective treatment in such immunocompromised patients. PMID:23774613

    Abstract Background Helminth infections are highly prevalent in tropical and subtropical countries, coexisting in Chagas disease endemic areas. Helminth infections in humans may modulate the host immune system, changing the Th1/Th2 polarization. This immunological disturbance could modify the immune response to other infections. The aim of this study is to evaluate the relationship between clinical, microbiological and epidemiological characteristics of Chagas disease patients, with the presence of helminth infection. Methods A prospective observational study was conducted at Vall d’Hebron University Hospital (Barcelona, Spain). Inclusion criteria were: age over 18 years, diagnosis of Chagas disease, and not having received specific treatment for Chagas disease previously to the inclusion. The study protocol included Chagas disease assessment (cardiac and digestive evaluation, detection of T. cruzi DNA measured by PCR in peripheral blood), and helminth infection diagnosis (detection of IgG anti-Strongyloides stercoralis by ELISA, microscopic examination of stool samples from three different days, and specific faecal culture for S. stercoralis larvae). Results Overall, 65 patients were included, median age was 38 years, 75.4% were women and most of them came from Bolivia. Cardiac and digestive involvement was present in 18.5% and 27.7% of patients respectively. T. cruzi PCR was positive in 28 (43.1%) patients. Helminth infection was diagnosed in 12 (18.5%) patients. No differences were observed in clinical and epidemiological characteristics between patients with and without helminth infection. Nevertheless, the proportion of patients with positive T. cruzi PCR was higher among patients with helminth infection compared with patients without helminth infection (75% vs 35.8%, p = 0.021). Conclusions We observed a high prevalence of S. stercoralis infection among chronic Chagas disease patients attended in our tropical medicine unit. Strongyloidiasis was associated

    2014-01-01

    Full Text Available Background: Different studies underline the use of pre-operative antibiotic prophylaxis in clean surgeries like herniotomy and inguinal orchiopexy. But, the meta-analyses do not recommend nor discard the use of prophylactic pre-operative antibiotics. The scarcity of controlled clinical trials in paediatric population further vitiates the matter. This study assessed the difference in the rate of early post-operative wound infection cases in children who received single dose of pre-operative antibiotics and children who did not receive antibiotics after inguinal herniotomy and orchiopexy. Materials and Methods: This randomised prospective study was conducted in Paediatric Surgery department of PGIMER Chandigarh. Out of 251 patients, 112 patients were randomised to the case group and 139 were ascribed to the control group. The patients in control group were given a standard regimen of single dose of intravenous antibiotic at the time of induction followed by 3-4 days of oral antibiotic. Case group patients underwent the surgical procedure in similar manner with no antibiotic either at the time of induction or post-operatively. Results: The incidence of surgical site infection in case group was 3.73 % and that in control group was 2.22%. The observed difference in the incidence of surgical site infection was statistically insignificant (P value = 0.7027. The overall infection rate in case and control group was 2.89%. Conclusions: Our preliminary experience suggests that there is no statistically significant difference in the proportion of early post-operative wound infection between the patients who received single dose of pre-operative antibiotics and the patients who received no antibiotics after inguinal herniotomy and orchiopexy. The risk of surgical site infection in paediatric heriotomies does not increase even if the child′s weight is less than his/her expected weight for age.

    Full Text Available Abstract. Enteroviruses are widely distributed human infectious pathogens. In spite of infection a disease does not manifest in majority number of cases. However, in some infected persons the different kind of symptoms can be observed; from common cold signs up to  aseptic (serous meningitis and myocarditis. Severe enteroviral cases with lethal outcomes are rarely reported. Ability of enteroviruses to cause large outbreaks and even epidemic distribution is very significant for health care systems. Taking in account a high genetic diversity of enteroviruses it is possible appearance of new highly pathogenic strains in the future. In some countries including the Russian Federation the permanent surveillance for enteroviral infections is provided besides of WHO polio elimination program. The laboratory diagnostics of enterovirus infections is complicated by numerous of pathogen serotypes. Thus, classical virological methods should be supported by molecular-biological tools to sequence pathogen genome and to define phylogenetic relations between different enterovirus strains.

    2016-02-01

    BACKGROUND In November and December 2012, 6 patients at a hemodialysis clinic were given a diagnosis of new hepatitis C virus (HCV) infection. OBJECTIVE To investigate the outbreak to identify risk factors for transmission. METHODS A case patient was defined as a patient who was HCV-antibody negative on clinic admission but subsequently was found to be HCV-antibody positive from January 1, 2008, through April 30, 2013. Patient charts were reviewed to identify and describe case patients. The hypervariable region 1 of HCV from infected patients was tested to assess viral genetic relatedness. Infection control practices were evaluated via observations. A forensic chemiluminescent agent was used to identify blood contamination on environmental surfaces after cleaning. RESULTS Eighteen case patients were identified at the clinic from January 1, 2008, through April 30, 2013, resulting in an estimated 16.7% attack rate. Analysis of HCV quasispecies identified 4 separate clusters of transmission involving 11 case patients. The case patients and previously infected patients in each cluster were treated in neighboring dialysis stations during the same shift, or at the same dialysis station on 2 consecutive shifts. Lapses in infection control were identified. Visible and invisible blood was identified on multiple surfaces at the clinic. CONCLUSIONS Epidemiologic and laboratory data confirmed transmission of HCV among numerous patients at the dialysis clinic over 6 years. Infection control breaches were likely responsible. This outbreak highlights the importance of rigorous adherence to recommended infection control practices in dialysis settings. PMID:26573412

    Closure of defects after trauma or excision of neoplasms is a basic skill in plastic surgery. Local, regional and distant flaps lead to additional scars. Skin recruitment by serial excision or skin expansion is a less damaging option for defects that must be closed. Advantages of tissue expansion include good colour and texture match. Disadvantages are the need for a second operation, use of an implant with the attendant risk of infection, time needed for inflation of the device, repeat visits to the clinic, and punctures to inflate the expander. To overcome the last disadvantage, an osmotic expander was developed in Germany in 1999 by OSMED GmbH (Ilmenau). PMID:18755643

    Participants were recruited from a sexually transmitted disease (STD) clinic in Florida and were assessed regarding the knowledge and awareness of non-AIDS conditions associated with HIV infection. Questionnaires were administered before and after a brief information session on non-AIDS conditions associated with HIV infection. Participants included men (n = 46) and women (n = 51). Prior to the information session, at baseline, only 34% of the participants were worried about HIV infection. Most participants (82%) agreed that HIV could be treated with antiretroviral therapy (ART), while only 38% were aware that HIV-associated conditions cannot be easily treated with ART. After the information session, almost all participants reported they were concerned regarding the risk of HIV infection. High-risk patients may have limited knowledge about the consequences of HIV infection beyond the traditional AIDS-associated conditions. Increased awareness of these less known consequences of HIV infection may decrease the potential for complacency regarding acquiring HIV infection. PMID:25331221

    Full Text Available Background: Frequent infections is among the most frequent clinical dilemmas for primary care physicians. Immunodeficiency disorders are a heterogeneous group of illnesses that predispose patients to the recurrent infections, autoimmunity and malignancies. The aim of this study was to evaluate the clinical and laboratory data collected for the final diagnosis of patients referred with recurrent infections and suspected immunodeficiency to a local immunodeficiency clinic.   Methods: This epidemiological study was carried out between April 2010 and September 2012 at the Immunodeficiency Clinic of Mashhad. All patients with clinical manifestations of immunodeficiency who were referred to our clinic during this period of time were included in this study. 41 patients aged from 10 months to 51 years, were evaluated. Results: Forty one patients, aged between 10 months and 51 years were evaluated. Eleven patients had a primary immunodeficiency, four cases had a secondary immunodeficiency, in three patients an underlying structural disease were found, eight patients were predisposed to recurrent infections as a result of allergies and finally, fifteen cases were found to be normal individuals.   Discussion: Most patients with recurrent infection have a normal immune system. Allergic disorders are the most common predisposing factor to recurrent infection. However, as immunodeficiency disorders are potentially serious, early diagnosis can improve the quality of life and outcome and prevent severe sequels in future.

    Between November 1985 and November 1989, 54 patients have undergone 55 cardiac transplants, 5 of whom died during operation or one week after transplantation. The remaining 49 patients with a minimum follow-up of 5 months were studied to examine pulmonary infection clinically and radiologically while receiving triple drug immunosuppression consisting of cyclosporine, azathioprine, and prednisolone. Pulmonary infection occurred in 14 patients (29%) with a total of 21 occasions. Causative organisms were identified in 9 occasions, with the most common organism being Cytomegalovirus (CMV). One patient died of pulmonary infection with Aspergillus. Causative organisms occurring in the remaining 12 occasions of pulmonary infection were unknown, which did not lead to death. Because pulmonary infection of unknown organisms rapidly responded to convensional antibiotics, it seemed to have been caused by bacteria. Pulmonary infection of unknown organism occurred 13.2{+-}3.2 months after transplantation, as compared with 3.3{+-}1.0 months in pulmonary infection of known organisms. Chest plain radiographic features fell into four types: (1) interstitial shadow seen in pulmonary infection of CMV, Pneumocystis carinii, or Hemophilia influenza, (2) patchy, and basilar and lobular consolidation shadows in bacterial pneumonia, (3) localized nodular shadow in aspergillosis, and (4) multiple patchy and confluent opacity patterns occurring in herpes simplex viral infection. Pulmonary infection of influenza bacteria for one patient and pulmonary infection of unknown organisms for 4 patients were difficult to identify from pulmonary infection of CMV. (N.K.).

    Full Text Available Co-infection with hepatitis C virus (HCV and human immunodeficiency virus (HIV is increasingly common and affects the clinical course of chronic hepatitis C. Highly active antiretroviral therapy has improved the life expectancy of HIV infected patients, but, by extending survival, it permits the development of HCV cirrhosis. This study tried to evaluate clinical and epidemiological features of patients with chronic hepatitis C co-infected with HIV. We evaluated 134 HCV-infected patients: i group A - 65 co-infected HCV/HIV patients, ii group B - 69 mono-infected HCV patients. The impact of HIV infection on HCV liver disease was analyzed using Child's score, ultrasound findings and liver histology. Patients were subjected to HCV genotyping and anti-HBs dosage. Patients mean age was 42.4 years (±9.1 and 97 (72.4% were males. Injected drug use and homo/bisexual practice were more frequently encountered in the co-infected group: 68.3% and 78.0%, respectively. Antibodies against hepatitis B virus (anti-HBs were found in only 38.1% of the patients (66.7% group A x 33.3% group B. Ten out of 14 individuals (71.4% who had liver disease (Child B or C and 25 out of 34 (73.5% who showed ultrasound evidence of chronic liver disease were in the co-infection group. HCV genotype-2/3 was more frequently encountered in co-infected patients (36.9% group A vs. 21.8% group B. Conclusions: a HIV infection seems to adversely affect the clinical course of chronic hepatitis C, b injected drug use, bi/homosexual practice and genotype-2/3 were more frequently encountered in co-infected patients, c immunization against HBV should be encouraged in these patients.

    The clinical learning environment is a complex social entity that influences student learning outcomes in the clinical setting. Exploration of this environment gives insight into the educational functioning of the clinical areas and allows nurse teachers to enhance students' opportunities for learning. Since Cyprus is undergoing major reforms in nursing education, building on the experience and knowledge gained, this study aims to explore the present clinical situation and how this would impact on nursing education moves to the university. As nursing education would take on a different approach, it is assumed the learning approach would also be different, and so utilization of the clinical environment would also be improved. Six hundred and forty five students participated in the study. Data were collected by means of the clinical learning environment and supervision instrument. A statistically significant correlation was found between the sub-dimensions "premises of nursing care" and "premises of learning" indicating that students are relating learning environment with the quality of nursing care and patient relationships. The ward atmosphere and the leadership style of the manager were rated as less important factors for learning. The majority of students experienced a group supervision model, but the more satisfied students were those with a "personal mentor" that was considered as the most successful mentor relationship. The findings suggest more thorough examination and understanding of the characteristics of the clinical environment that are conductive to learning. PMID:19700368

  3. Clinical and biological differences between recurrent herpes simplex virus and varicella-zoster virus infections

    International Nuclear Information System (INIS)

    The major features that distinguish recurrent herpes simplex virus infections from zoster are illustrated in this article by two case histories. The clinical and epidemiologic features that characterize recurrent herpes simplex virus and varicella-zoster virus infections are reviewed. It is noted that herpesvirus infections are more common and severe in patients with cellular immune deficiency. Each virus evokes both humoral and cellular immune response in the course of primary infection. DNA hybridization studies with RNA probes labelled with sulfur-35 indicate that herpes simplex viruses persist within neurons, and that varicella-zoster virus is found in the satellite cells that encircle the neurons

    Full Text Available Introduction Catheter-associated urinary tract infections are the most common nosocomial infections of the urinary tract, and among the most common nosocomial infections in general. The major problems of these infections include antibiotic resistance and enormous direct and indirect cost of treatment. Material and methods A retrospective study on major causes of infections and antibiotic resistance was conducted at four clinics of the Clinical Center of Banja Luka. An anonymous questionnaire was distributed to nursing staff dealing with urinary catheters in order to get an overview of their clinical performance. Results The results showed that in 89% of cases (out of 198 patients with developed catheter-associated urinary tract infection infections were caused by gram-negative bacteria, in 7% by gram-positive bacteria and in 4% by Candida. The most common bacteria were: Escherichia coli (33.6%, Pseudomonas aeruginosa (14.1%, Proteus mirabilis (13.3%, and Enterobacter (10.5%. Majority of bacteria presented with extremely high resistance (72-100% to ampicillin, gentamycin and cotrimoxazole, and in some cases a significant resistance to ciprofloxacine, nalidixic acid, ceftriaxone and ceftazidime. The questionnaire showed that nursing staff did not follow guidelines for medical care of patients with urinary catheters. Conclusion It can be concluded that poor hygienic and epidemiological conditions, as well as irrational use of antibiotics contribute to uncontrolled development of urinary tract infections in catheterized patients.

    Full Text Available Intestinal helminth infections during pregnancy are associated with adverse outcomes including low birth weight and prenatal mortality. The infections are a major public health problem in developing countries. A hospital based survey was undertaken for six months to determine the infection prevalence, intensity, and risk factors. The study involved expectant women attending antenatal clinic. Stool samples were screened microscopically for helminth ova using Kato Katz technique. Information on risk factors was collected using semistructured questionnaire and analyzed using SPSS. Epidemiological data was analysed using descriptive statistics and multivariate analysis. The overall prevalence of infection was 21 (13.8%. Ascariasis was the most prevalent 10 (6.5%, hookworm infection was 6 (3.9%, and trichuriasis was 2 (1.3%. Pregnant women aged below 29 years (OR = 3.63, CI = 0.87–11.75 and those with primary level of education (OR = 3.21, CI = 0.88–11.75 were at a higher risk of infection compared to those aged ≥ 29 years with secondary level of education. Hand washing was significantly associated with reduced likelihood of infection (OR = 0.18, 95% CI = 0.06–0.57. It was concluded that intestinal helminth infections were prevalent among pregnant women. We recommended that all expectant women visiting antenatal clinics be screened for intestinal helminth infections and positive cases be advised to seek treatment.

    Full Text Available Managing hematological disorders in a tropical country presents several unique diagnostic and management problems. Apart from the disease process, we need to be aware of infections that can exacerbate or mimic serious hematological problems. We present here a series of five patients with pre-existing hematological diseases who were infected by dengue virus. These cases highlight the need to keep a strong suspicion of common endemic diseases in tropical countries before considering extensive workup for the basic hematological disease. There was no mortality and all patients recovered without any significant impact on their pre-existing hematological condition inspite of their low baseline blood counts. There was no excessive bleeding, prolonged stay in the hospital or relapse of underlying hematological disease in these patients and the only major concern was the increased anxiety among both the patient and treating physician regarding the relapse/progression of pre-existing hematological disease.

    Full Text Available BACKGROUND: Dengue infection is one of the most important mosquito-borne diseases. More data regarding the disease burden and the prevalence of each clinical spectrum among symptomatic infections and the clinical manifestations are needed. This study aims to describe the incidence and clinical manifestations of symptomatic dengue infection in Thai children during 2006 through 2008. STUDY DESIGN: This study is a school-based prospective open cohort study with a 9,448 person-year follow-up in children aged 3-14 years. Active surveillance for febrile illnesses was done in the studied subjects. Subjects who had febrile illness were asked to visit the study hospital for clinical and laboratory evaluation, treatment, and serological tests for dengue infection. The clinical data from medical records, diary cards, and data collection forms were collected and analyzed. RESULTS: Dengue infections were the causes of 12.1% of febrile illnesses attending the hospital, including undifferentiated fever (UF (49.8%, dengue fever (DF (39.3% and dengue hemorrhagic fever (DHF (10.9%. Headache, anorexia, nausea/vomiting and myalgia were common symptoms occurring in more than half of the patients. The more severe dengue spectrum (i.e., DHF had higher temperature, higher prevalence of nausea/vomiting, abdominal pain, rash, diarrhea, petechiae, hepatomegaly and lower platelet count. DHF cases also had significantly higher prevalence of anorexia, nausea/vomiting and abdominal pain during day 3-6 and diarrhea during day 4-6 of illness. The absence of nausea/vomiting, abdominal pain, diarrhea, petechiae, hepatomegaly and positive tourniquet test may predict non-DHF. CONCLUSION: Among symptomatic dengue infection, UF is most common followed by DF and DHF. Some clinical manifestations may be useful to predict the more severe disease (i.e., DHF. This study presents additional information in the clinical spectra of symptomatic dengue infection.

    Data from epidemiologic studies suggest that hookworm infections, in establishing an immunologic phenotype conducive to parasite survival, may protect against the development of allergic disease. We describe immunologic findings from a clinical study designed to investigate the safety of iatrogenic hookworm infection in participants with allergic rhinitis. The low, relatively safe level of hookworm infection used in this study was immunogenic, inducing eosinophilia and a significant specific IgG response. Importantly, no potentiation of IgE responses to the environmental allergens to which the participants were sensitized was seen. However, no evidence of systemic immune regulation was seen in infected participants. This finding may indicate that the level of infection or the frequency of infection may have to be altered in future trials to induce a therapeutically conducive immunologic phenotype. PMID:19861631

    Full Text Available Three groups of pregnant Yankasa (YK and West African Dwarf (WAD ewes, made up of 6pregnant YK and 6 pregnant WAD ewes in each group, were assigned at random to first, second and third trimester of pregnancy, to study the clinical manifestation of. T. vivax infection at each trimester of pregnancy. A fourth group made up of 3 pregnant YK and 3 pregnant WAD ewes served as the non-infected controls for the study. Pre- infection mean rectal temperatures of the YK and WAD ewes were 38.6 Co and 38.7 Crespectively, while post-infection temperatures were as high as 41.5 C and 41.6 C for the YK and WAD ewes respectively. The infection was severe in the infected YK and WAD ewes in the second and third trimesters of pregnancy and most severe in YK than in the WAD ewes. The infected YK and WAD ewes exhibited pyrexia, signs of anaemia shown by pale mucus membrane, decrease in packed cell volume (PCV values, decrease in total plasma protein (TP values, weight loss, lethargy, dullness, abortions and death of ewes. The severity of the infection increased as the pregnancy advanced in the ewes. WAD ewes in the first trimester were least susceptible to the infection and self-cure was observed in one WAD ewe. The infected WAD ewes controlled the effects of the infection on abortions and mortality more than the YK ewes. It was concluded from the study that the trimester of pregnancy and breed of ewe influenced the clinical manifestation of T. vivax infection on pregnant YK and WAD ewes.

    Full Text Available This study aimed at evaluating the susceptibility of commercial laying hens to Salmonella Gallinarum (SG. Two experiments were carried using a mutant strain of Salmonella Gallinarum resistant to nalidix acid (SGNALr. In the first trial, the resistance of birds was evaluated based on clinical signs, faecal shedding, and mortality. It was carried out with six lines of commercial layers being three light white layers, considered to be resistant to SG (W1, W2, W3, and three semi-heavy brown varieties (B1, B2, B3, considered susceptible to SG. Each group contained 15 one-day-old birds. Hens were inoculated in the crop at 5 days of age with 0.2 mL of SGNALr neat culture. In addition, to each brown variety, a new group of 15 birds was challenged with 0.2mL of the same SGNALr culture diluted at 10-3. At the end of the first experiment, the surviving birds were sacrificed, and microbiological culture of liver and spleen was performed. In the second experiment, white and brown birds were inoculated with neat culture at five days of age. Samples were collected for evaluation of blood parameters and histopathology assessment at 1, 3, 5, 7, 9, 12, and 14 days post-infection. The results of the first experiment showed higher resistance of white birds (p<0.05, although there was no uniformity in the responses against fowl typhoid among the birds within these groups. In the second experiment, there were differences between white and brown birds both in blood parameters and in organ lesion intensity.

  18. Chest wall tuberculosis - A clinical and imaging experience

    International Nuclear Information System (INIS)

    Tuberculous infection of the thoracic cage is rare and is difficult to discern clinically or on radiographs. This study aims to describe the common sites and the imaging appearances of chest wall tuberculosis. A retrospective review of the clinical and imaging records of 12 confirmed cases of thoracic cage tuberculosis (excluding that of the spine), seen over the last 7 years, was performed. Imaging studies available included radiographs, ultrasonographies (USGs), and computed tomography (CT) scans. Pathological confirmation was obtained in all cases. All patients had clinical signs and symptoms localized to the site of involvement, whether it was the sternum, sternoclavicular joints, or ribs. CT scan revealed sternal destruction in three patients and osteolytic lesions with sclerosis of the articular surfaces of the sternoclavicular joints in two patients. In five patients with rib lesions, USG elegantly demonstrated the bone destruction underlying the cold abscess. All cases were confirmed to be of tuberculous origin by pathology studies of the aspirated/curetted material, obtained by CT / USG guidance. Tuberculous etiology should be considered for patients presenting with atypical sites of skeletal inflammation. CT scan plays an important role in the evaluation of these patients. However, the use of USG for demonstrating rib destruction in a chest wall cold abscess has so far been under-emphasized, as has been the role of CT and USG guided aspiration in confirming the aetiology

    Full Text Available DNA-abzymes enzymes in autoimmune diseases in clinic and experiment T.E. Naumova, O.M. Durova, A.G. Gabibov, Z.S. Alekberova, S. V. Suchkov DNA-hydrolyzing autoantibodies (AAB or DNA-abzymes can be found in autoimmune diseases in clinic and experiment. Technology of serum express screening for presence of DNA abzymes is described. Comparative study of DNA-hydrolising activity in patients with different forms of systemic and organ-specific autoimmune diseases was performed. Blood of clinically healthy donors was usually free of IgG DNA-abzymes. DNA-abzymes were most often revealed in patients with systemic lupus erythematosus (SLE and rheumatoid arthritis (RA less often in patients with organ-specific forms of autoimmune disturbances. The results of the study confirm the hypothesis of autoimmune origin of IgG DNA abzymes and demonstrate the possibility to use them in clinical practice for monitoring to disease activity in SLE and RA.

    Full Text Available Abstract Background Shared decision-making has been advocated; however there are relatively few studies on physician preferences for, and experiences of, different styles of clinical decision-making as most research has focused on patient preferences and experiences. The objectives of this study were to determine 1 physician preferences for different styles of clinical decision-making; 2 styles of clinical decision-making physicians perceive themselves as practicing; and 3 the congruence between preferred and perceived style. In addition we sought to determine physician perceptions of the availability of time in visits, and their role in encouraging patients to look for health information. Methods Cross-sectional survey of a nationally representative sample of U.S. physicians. Results 1,050 (53% response rate physicians responded to the survey. Of these, 780 (75% preferred to share decision-making with their patients, 142 (14% preferred paternalism, and 118 (11% preferred consumerism. 87% of physicians perceived themselves as practicing their preferred style. Physicians who preferred their patients to play an active role in decision-making were more likely to report encouraging patients to look for information, and to report having enough time in visits. Conclusion Physicians tend to perceive themselves as practicing their preferred role in clinical decision-making. The direction of the association cannot be inferred from these data; however, we suggest that interventions aimed at promoting shared decision-making need to target physicians as well as patients.

    O'Driscoll, Tristan; Crank, Christopher W

    2015-01-01

    Since its discovery in England and France in 1986, vancomycin-resistant Enterococcus has increasingly become a major nosocomial pathogen worldwide. Enterococci are prolific colonizers, with tremendous genome plasticity and a propensity for persistence in hospital environments, allowing for increased transmission and the dissemination of resistance elements. Infections typically present in immunosuppressed patients who have received multiple courses of antibiotics in the past. Virulence is variable, and typical clinical manifestations include bacteremia, endocarditis, intra-abdominal and pelvic infections, urinary tract infections, skin and skin structure infections, and, rarely, central nervous system infections. As enterococci are common colonizers, careful consideration is needed before initiating targeted therapy, and source control is first priority. Current treatment options including linezolid, daptomycin, quinupristin/dalfopristin, and tigecycline have shown favorable activity against various vancomycin-resistant Enterococcus infections, but there is a lack of randomized controlled trials assessing their efficacy. Clearer distinctions in preferred therapies can be made based on adverse effects, drug interactions, and pharmacokinetic profiles. Although combination therapies and newer agents such as tedizolid, telavancin, dalbavancin, and oritavancin hold promise for the future treatment of vancomycin-resistant Enterococcus infections, further studies are needed to assess their possible clinical impact, especially in the treatment of serious infections.

    A 4-month evaluation of ambulatory patients with a suspicion of a urinary tract infection was performed. Specific objectives included assessment of five urinary screening methods, reevaluation of the necessity of the phenylethyl alcohol plate (PEA), and cost-effectiveness of screening for low colony count bacteriuria. Urine samples were collected as midstream, clean-caught specimens. A total of 142 samples, 87 from 79 symptomatic patients and 55 negative controls, were evaluated. All urine specimens were cultured using a 0.01 mL loop and a 0.001 mL loop onto Columbia sheep blood agar, MacConkey agar, and PEA agar. Twenty-four specimens (17%) were sterile, 64 (45%) were contaminated, and 54 (38%) were infected. Five urine screening methods were performed. These tests and their associated sensitivity and specificity are as follows. The Chemstrip 9 (Behring, Inc., Somerville, NJ) for leukocyte esterase and nitrate, 67%, 98%; microscopic analysis on spun urine, 79%, 93%; methylene blue stain for pyuria, 60%, 99%; Gram stain for pyuria, 45%, 93%; Gram stain for bacteriuria, 65%, 75%; and the URISCREEN (Analytab Products, Plainview, NY), 92%, 89%. Inclusion of a PEA plate for isolation of gram-positive organisms provided no additional information. Routine culture of urine samples at 10(-2) mL increased the contamination rate by 19%.

    Full Text Available Objective: The aim of this study was to investigate clinical risk factors on survival among infected children born to HIV-positive mothers in the southern region of Thailand. Methods: Data from routine prospective cohort studies from 1990–2010 were analyzed. In these studies, totally 1549 infected children born to HIV-positive mothers were enrolled at birth and followed longitudinally. Information on demographic, clinical manifestation, HIV infection status factors was collected. Survival analysis was used to determine risk factors associated with mortality. Results: The main result found that one-quarter of infected children died (434, 28.02% during the follow-up period. A total of 135,295 person-months of follow up was available. The incident rate was 1.03 times per 100 person-months (95% CI: 0.97 to 1.08. The median survival time among infected children born to HIV-positive mothers from diagnosis to death was 87.34 months (95% CI: 87.32 to 87.36. Infected children born to HIV-infected mothers were diagnosed to confirm as AIDS (88.44% and symptomatic HIV positive (11.56%, respectively. Regarding the clinical risk factor on survival among infected children born to HIV-positive mothers were found. Infected children born to HIV-positive mothers were more likely to die, who infected with candidiasis (HR: 1.47, 95% CI: 1.07 to 2.00, Mycobacterium tuberculosis (HR: 1.51, 95% CI: 1.26 to 1.81 and Pneumocystis carinii (HR: 1.50, 95% CI: 1.27 to 1.76, those compared to infected children without clinical manifestation. Conclusion: Mortality among infected children born to HIV-positive mothers contributed to high levels in the southern region of Thailand. Consequently, health service system related to prevent mother-to-child HIV transmission is needed to improve child survival by lowering HIV infection and mortality in children born to HIV-positive mothers.

    2015-11-01

    Coinciding with the continually increasing population of immunocompromised patients worldwide, the incidence of invasive fungal infections has grown over the past 4 decades. Unfortunately, infections caused by both yeasts such as Candida and molds such as Aspergillus or Mucorales remain associated with unacceptably high morbidity and mortality. In addition, the available antifungals with proven efficacy in the treatment of these infections remain severely limited. Although previously available second-generation triazole antifungals have significantly expanded the spectrum of the triazole antifungal class, these agents are laden with shortcomings in their safety profiles as well as formulation and pharmacokinetic challenges. Isavuconazole, administered as the prodrug isavuconazonium, is the latest second-generation triazole antifungal to receive U.S. Food and Drug Administration approval. Approved for the treatment of both invasive aspergillosis and invasive mucormycosis, and currently under investigation for the treatment of candidemia and invasive candidiasis, isavuconazole may have therapeutic advantages over its predecessors. With clinically relevant antifungal potency against a broad range of yeasts, dimorphic fungi, and molds, isavuconazole has a spectrum of activity reminiscent of the polyene amphotericin B. Moreover, clinical experience thus far has revealed isavuconazole to be associated with fewer toxicities than voriconazole, even when administered without therapeutic drug monitoring. These characteristics, in an agent available in both a highly bioavailable oral and a β-cyclodextrin-free intravenous formulation, will likely make isavuconazole a welcome addition to the triazole class of antifungals.

In Sweden a common procedure manual is used nationwide, consisting of guidelines covering a wide range of nursing and medical procedures performed by the nursing staff. It is revised every fifth year. A recent enquiry to over 150 wards in some 100 hospitals demonstrated that the manual is widely accepted and used. In the other Scandinavian countries, guidelines and policies on a variety of infection control topics have been published. PMID:1679772

    Heteronormative assumptions can negatively influence the lives of young gay and bisexual men, and recent sociological analyses have identified the negative impacts of heteronormativity on heterosexual men (e.g. 'fag discourse' targeted at heterosexual adolescents). However, insights into how heteronormative discourses may be (re)produced in clinical settings and how they contribute to health outcomes for gay, bisexual and heterosexual men are poorly understood. This analysis draws on in-depth interviews with 45 men (15-25 years old) and 25 clinicians in British Columbia, Canada, to examine how heteronormative discourses affect sexually transmitted infection testing. The sexually transmitted infection/HIV testing experience emerged as a unique situation, whereby men's (hetero)sexuality was explicitly 'interrogated'. Risk assessments discursively linked sexual identity to risk in ways that reinforced gay men as the risky 'other' and heterosexual men as the (hetero)normal and, therefore, relatively low-risk patient. This, in turn, alleviated concern for sexually transmitted infection/HIV exposure in heterosexual men by virtue of their sexual identity (rather than their sexual practices), which muted discussions around their sexual health. The clinicians also positioned sexual identities and practices as important 'clues' for determining their patients' social contexts and supports while concurrently informing particular tailored clinical communication strategies. These findings highlight how men's experiences with sexually transmitted infection/HIV testing can (re)produce heteronormative assumptions and expectations or create opportunities for more equitable gendered relations and discourses.

    Two crossbred female calves aged between 30 and 35 days were presented with bilateral exophthalmia, inappetence, pyrexia and cachexia since last 15 days. Clinical examination revealed mainly bilateral exophthalmia with dry and pulpy cornea, generalized enlargement of superficial lymph nodes, pallor mucous, petechiae, high rectal temperature and sternal recumbency. The calves were severely infested with Hyalomma anatolicum anatolicum ticks and thin layer blood smears revealed presence of piroplasm in the RBCs, while lymph nodes aspirate smear examination revealed presence schizonts in the mononuclear cells. The calves were treated with buparvaquone; meloxicam, nandrolone decanoate and vitamins A, D3, E and H. From day second post-therapy a remarkable improvement in the clinical condition was noticed and substantial reduction in the both protruded eyeballs was noticed by 7 days post-therapy in the both calves. Further at day 47 post-therapy the one calf was free from the parasite on blood smear examination and right eye was retracted in its orbits with full of sight. Moreover the left eye was also retracted in its orbit but there was loss of sight and opacity developed in this eye. While, the other calf also revealed remarkable improvement in the clinical condition and both eye balls retracted completely into the orbit at day 30 post-therapy. But, at day 86 the calf developed microphthalmia and complete loss of sight in both eyes. It can be concluded that adjunction of antioxidants and hematopoietic agents may salvage the calves suffering from fatal theileriosis. PMID:26345050

  19. The clinical experience and results of total body irradiation for the cases of refractory leukemia

    International Nuclear Information System (INIS)

    Five patients suffering from refractory leukemia were treated by Cyclophosphamide and total body irradiation followed by bone marrow transplantation. Total body irradiation with 10 MV Linac x-ray (1000 - 1280 rad, peak absorbed dose) followed by bone marrow transplantation is considered to be a relatively safe procedure. The dose distribution of the total body irradiation shows clinically suitable homogeniety. Although there is no long-term survivor in this study, no relapse sign of leukemia was found at autopsy. Therefore, some possibility of cure can be expected from this experience. There are many problems such as Graft-versus-host disease, susceptability to infection, etc., but this combination therapy will be able to contribute to improve the clinical course of refractory leukemia.

    AIM: To find correlates to spontaneous clearance of hepatitis C virus (HCV) infection, this study compared individuals with self-limited and chronic infection with regard to clinical, demographic, and serological parameters.METHODS: Sixty-seven anti-HCV positive and repeatedly HCV RNA negative individuals were considered to have resolved HCV infection spontaneously. To determine the viral genotype these patients had been infected with HCV serotyping was performed. For comparison reasons,62 consecutive patients with chronic hepatitis C were enrolled. Cases and controls were compared stratified for age and sex.RESULTS: Retrospective analysis showed (1) a lower humoral reactivity to HCV in patients with self-limited compared to chronic HCV-infection and (2) that younger age, history of iv drug use, and acute/post-acute hepatitis A or B co-infections, but not viral genotypes,are independent correlates for spontaneous HCV clearance.CONCLUSION: The stronger humoral reactivity to HCV in patients with persistent infections and in those with a history of iv drug use is supposed to be due to continuous or repeated contact(s) to the antigen.Metachronous hepatitis A or hepatitis B infections might favor HCV clearance.

    Full Text Available Aim. Cystic fibrosis occurs as a consequence of mutations in the gene regulation of transmembrane message and shows autosomal recessive inheritance. The disease is more frequent among white people; Clinical findings and symptoms in cystic fibrosis can be very different due to the age of patients, type of mutation and complications. In our country, the most common complaints of cystic fibrosis patients in application to hospital are problems in respiratory tract and growth retardation. In this study, we aimed to findhe frequency of cystic fibrosis in children who applied to our clinic with growth retardation and/or recurrent pulmonary infections. Method. This prospective study was conducted between September 2009 and September 2010 in 218 children who applied to our clinic with symptoms of malnutrition and/or recurrent pulmonary infections and had not been diagnosed as cystic fibrosis before. These patients underwent sweat test and their clinical chracteristics were noted. The diagnosis of cystic fibrosis was made by using positive sweat test , appropriate clinical findings and by exclusion of other diseases that also cause recurrent pulmonary infections or malnutrition. Results. The mean age of children was 54.40 ± 48.70 months. Of all children, 100 (45.9% were male and 118 (54.1% were female. Positive sweat test was found in 9 (4.2% children. The frequency of cystic fibrosis was found to be 7.8% in children with recurrent pulmonary infections and 10.5% in children with weight percentile values <3 p. and 9.3% in children with height percentile values <3 p. Conclusion. Sweat test is clinically important for the early diagnosis of cystic fibrosis and in prevention of complications related to this disease in children with growth retardation or recurrent pulmonary infections.

  5. Clinical application of 99mTc-HMPAO labeled leucocytes imaging in detecting bone joint infection

    International Nuclear Information System (INIS)

    99mTc-MDP scintigraphy and 99mTc-HMPAO-leucocytes imaging were performed in twenty five patients with clinically suspected bone joint infection. All of the 25 cases were confirmed by surgery, microbiological and histologic examinations. Among them 21 cases were definitively diagnosed as infections, while 3 cases were non-infection. The results of 99mTc-MDP scintigraphy showed that all of 25 cases demonstrated anomalous accumulation of radioactivity in the clinically suspected infections sites, while in 99mTc-HMPAO-leucocytes imaging, concentrated radioactivity in proved infectious sites was observed in 19 cases, non-anomalous radioactivity found in 4 cases of non-infectious sites, but there were 2 cases false negative with long term antibiotics treatment, none of the case was false positive. Thereby a sensitivity of the labelled leucocytes imaging of 90.5%, a specificity of 100%, and a accuracy of about 92% were found. Present research work concluded that 99mTc-HMPAO labelled leucocytes imaging provided a non-invasive, effective, and reliable diagnostic method in detecting patients with clinically suspected bone joint infection and afforded strong evidence for effective therapy

    Helicobacter pylori (HP) infection can cause hypochlorhydria, a positive risk factor for Mycobacterium tuberculosis (MTB) infection. This study examined the association between HP and MTB infections among persons attending the Policlinico Peruano Japonés Gastrointestinal Clinic in Lima, Peru. From 23 June 2000 to 18 August 2000, consenting 18-55 year olds who attended the clinic for gastric biopsy gave blood for HP serologic testing, underwent tuberculin skin testing (TST) and completed a social and medical history. Of 128 participating patients, 78 (61%) were TST positive for MTB, and 107 (84%) were infected with HP by serology. Of the patients who were HP positive, 67 (63%) developed positive TST reactions compared to 11 (52%) of 21 HP-seronegative subjects (OR 1.29; 95% CI 0.54-3.11; P = 0.6). There was no association after adjusting for covariates of H. pylori infection (OR 0.78; 95% CI 0.23-2.71; P = 0.7). However, study power was limited by high prevalence of the two infections.

    Full Text Available Viral infection is one of the risk factors for asthma exacerbation. However, which pathogens are related to asthma exacerbation in adults remains unclear.The relation between various infections and adult asthma exacerbations was investigated in clinical practice.The study subjects included 50 adult inpatients due to asthma exacerbations and 20 stable outpatients for comparison. The pathogens from a nasopharyngeal swab were measured by multiplex PCR analysis.Asthma exacerbations occurred after a common cold in 48 inpatients. The numbers of patients with viral, bacterial, or both infections were 16, 9, and 9, respectively. The dominant viruses were rhinoviruses, respiratory syncytial virus, influenza virus, and metapneumovirus. The major bacteria were S. pneumoniae and H. influenzae. Compared to pathogen-free patients, the patients with pathogens were older and non-atopic and had later onset of disease, lower FeNO levels, lower IgE titers, and a higher incidence of comorbid sinusitis, COPD, or pneumonia. Compared to stable outpatients, asthma exacerbation inpatients had a higher incidence of smoking and comorbid sinusitis, COPD, or pneumonia. Viruses were detected in 50% of stable outpatients, but a higher incidence of rhinovirus, respiratory syncytial virus, and metapneumovirus infections was observed in asthma exacerbation inpatients. H. influenzae was observed in stable asthmatic patients. Other bacteria, especially S. pneumoniae, were important in asthma exacerbation inpatients.Viral or bacterial infections were observed in 70% of inpatients with an asthma exacerbation in clinical practice. Infection with S. pneumoniae was related to adult asthma exacerbation.

    Background: Pulmonary nocardiosis is a rare but a life-threatening infection caused by Nocardia spp. The diagnosis is often missed and delayed resulting in delay in appropriate treatment and thus higher mortality. Aim: In this study, we aim to evaluate the clinical spectrum and outcome of patients with pulmonary nocardiosis. Methods: A retrospective, 5-year (2009–2014) review of demographic profile, risk factors, clinical manifestations, imaging findings, treatment, and outcome of patients with pulmonary nocardiosis admitted to a tertiary care hospital. Results: The median age of the study subjects was 54 years (range, 16–76) and majority of them (75%) were males. The risk factors for pulmonary nocardiosis identified in our study were long-term steroid use (55.6%), chronic lung disease (52.8%), diabetes (27.8%), and solid-organ transplantation (22.2%). All the patients were symptomatic, and the most common symptoms were cough (91.7%), fever (78%), and expectoration (72%). Almost two-third of the patients were initially misdiagnosed and the alternative diagnosis included pulmonary tuberculosis (n = 7), community-acquired pneumonia (n = 5), lung abscess (n = 4), invasive fungal infection (n = 3), lung cancer (n = 2), and Wegener's granulomatosis (n = 2). The most common radiographic features were consolidation (77.8%) and nodules (56%). The mortality rate for indoor patients was 33% despite treatment. Higher mortality rate was observed among those who had brain abscess (100.0%), HIV positivity (100%), need for mechanical ventilation (87.5%), solid-organ transplantation (50%), and elderly (age > 60 years) patients (43%). Conclusion: The diagnosis of pulmonary nocardiosis is often missed and delayed resulting in delay in appropriate treatment and thus high mortality. A lower threshold for diagnosing pulmonary nocardiosis needs to be exercised, in chest symptomatic patients with underlying chronic lung diseases or systemic immunosuppression, for the early diagnosis

    We used qualitative methods to explore factors, which might explain increased anxiety in patients attending a sexually transmitted infection (STI) clinic. Twenty patients, who scored significantly for anxiety on the Hospital Anxiety and Depression Scale (HADS) attended a 20-minute interview. This explored factors contributing to their current psychological symptoms. Transcripts revealed three main themes. First were factors related to possible STIs and the clinic visit. These included health anxieties about HIV or fertility and clinic factors, including staff attitudes and clinic location. Second were factors unrelated to the clinic, including previous emotional difficulties or substance misuse. Third were issues concerning stigma, embarrassment and shame. The origins of anxiety in STI patients are multifactorial and difficult to identify during brief appointments. Despite modern clinics and attitudes, stigma and embarrassment remain prominent. Interventions to address these factors could improve psychological health in this patient group. PMID:16643678

    The purpose of the postmortem examination is to offer answers to explain the cause and manner of death. In the case of perinatal, infant and paediatric postmortem examinations, the goal is to identify unsuspected associated features, to describe pathogenic mechanisms and new conditions, and to evaluate the clinical management and diagnosis. Additionally, the postmortem examination is useful to counsel families regarding the probability of recurrence in future pregnancies and to inform family planning. Worldwide the rate of paediatric autopsy examinations has significantly declined during the last few decades. Religious objections to postmortem dissection and organ retention scandals in the United Kingdom provided some of the impetus for a search for non-invasive alternatives to the traditional autopsy; however, until recently, imaging studies remained an adjunct to, rather than a replacement for, the traditional autopsy. In 2012, Sheffield Children's Hospital National Health Service Foundation Trust set up the service provision of minimally invasive fetal, perinatal and neonatal autopsy, while a postmortem imaging service has been running in Melbourne, Australia, since 2008. Here we summarise the essentials of a business case and practical British and Australian experiences in terms of the pathological and radiologic aspects of setting up a minimally invasive clinical service in the United Kingdom and of developing a clinical postmortem imaging service as a complementary tool to the traditional autopsy in Australia.

  15. Simple clinical and laboratory predictors of Chikungunya versus dengue infections in adults.

    Directory of Open Access Journals (Sweden)

    Vernon J Lee

    Full Text Available BACKGROUND: Dengue and chikungunya are co-circulating vector-borne diseases with substantial overlap in clinical presentations. It is important to differentiate between them during first presentation as their management, especially for dengue hemorrhagic fever (DHF, is different. This study compares their clinical presentation in Singapore adults to derive predictors to assist doctors in diagnostic decision-making. METHODS: We compared 117 patients with chikungunya infection diagnosed with reverse transcription-polymerase chain reaction (RT-PCR with 917 dengue RT-PCR-positive adult patients (including 55 with DHF. We compared dengue fever (DF, DHF, and chikungunya infections by evaluating clinical characteristics of dengue and chikungunya; developing classification tools via multivariate logistic regression models and classification trees of disease etiology using clinical and laboratory factors; and assessing the time course of several clinical variables. FINDINGS: At first presentation to hospital, significantly more chikungunya patients had myalgia or arthralgia, and fewer had a sore throat, cough (for DF, nausea, vomiting, diarrhea, abdominal pain, anorexia or tachycardia than DF or DHF patients. From the decision trees, platelets <118 × 10(9/L was the only distinguishing feature for DF versus chikungunya with an overall correct classification of 89%. For DHF versus chikungunya using platelets <100 × 10(9/L and the presence of bleeding, the overall correct classification was 98%. The time course analysis supported platelet count as the key distinguishing variable. INTERPRETATION: There is substantial overlap in clinical presentation between dengue and chikungunya infections, but simple clinical and laboratory variables can predict these infections at presentation for appropriate management.

    Infections with carbapenem-resistant Enterobacteriaceae (CRE) are an emerging cause of morbidity and mortality among liver transplant recipients (LTR) worldwide, particularly Klebsiella pneumoniae carbapenemase (KPC)-producing organisms. Approximately 3 - 13 % of solid organ transplant recipients in CRE-endemic areas develop CRE infections, and the infection site correlates with the transplanted organ. The cumulative 30-day mortality rate of LTR infected with carbapenem-resistant K. pneumoniae is 36 %, and the 180-day mortality rate is 58 %. Awareness of the high vulnerability of LTR to fatal bacterial infection leads to the more frequent use of ultrabroad-spectrum empirical antibiotic therapy, which further contributes to the selection of extreme drug resistance. Moreover, it comprises a relevant risk of failure to initiate adequate empirical treatment due to the fact that culture-based techniques used to identify CRE imply a 48- to 72-hour delay from blood culture collection until administration of the targeted therapy. This vicious circle is difficult to avoid and leads to increased clinical intricacy and narrowed antimicrobial therapeutic options. Because available options are extremely limited, infection prevention measures have gained outstanding importance, particularly in the phase after liver transplant requiring intense immunosuppression early on. Improving clinical outcomes is a major challenge and involves a multi-targeted approach combining strictly applied hygiene measures, active surveillance tests, the use of modern, time-saving methods of molecular biology, and enforced antibiotic stewardship. This article reviews the current literature regarding the incidence and outcome of CRE infections in LTR, and it summarises current preventive and therapeutic recommendations to minimise the threat by CRE in real-life clinical transplant settings.

    Background Infective spondylodiscitis usually occurs in patients of older age, immunocompromisation, co-morbidity, and individuals suffering from an overall poor general condition unable to undergo reconstructive anterior and posterior surgeries. Therefore, an alternative, less aggressive surgical method is needed for these select cases of infective spondylodiscitis. This retrospective clinical case series reports our novel surgical technique for the treatment of infective spondylodiscitis. Methods Between January 2005 and July 2011, among 48 patients who were diagnosed with pyogenic lumbar spondylodiscitis or tuberculosis lumbar spondylodiscitis, 10 patients (7 males and 3 females; 68 years and 48 to 78 years, respectively) underwent transpedicular curettage and drainage. The mean postoperative follow-up period was 29 months (range, 7 to 61 months). The pedicle screws were inserted to the adjacent healthy vertebrae in the usual manner. After insertion of pedicle screws, the drainage pedicle holes were made through pedicles of infected vertebra(e) in order to prevent possible seeding of infective emboli to the healthy vertebra, as the same instruments and utensils are used for both pedicle screws and the drainage holes. A minimum of 15,000 mL of sterilized normal saline was used for continuous irrigation through the pedicular pathways until the drained fluid looked clear. Results All patients' symptoms and inflammatory markers significantly improved clinically between postoperative 2 weeks and postoperative 3 months, and they were satisfied with their clinical results. Radiologically, all patients reached the spontaneous fusion between infected vertebrae and 3 patients had the screw pulled-out but they were clinically tolerable. Conclusions We suggest that our method of transpedicular curettage and drainage is a useful technique in regards to the treatment of infectious spondylodiscitic patients, who could not tolerate conventional combined anterior and posterior

    2012-08-01

    Full Text Available Abstract Background Climate change is a global public health problem that will require complex thinking if meaningful and effective solutions are to be achieved. In this conceptual paper we argue that GPs have much to bring to the issue of climate change from their wide-ranging clinical experience and from the principles underpinning their clinical methods. This experience and thinking calls forth particular contributions GPs can and should make to debate and action. Discussion We contend that the privileged experience and GP way of thinking can make valuable contributions when applied to climate change solutions. These include a lifetime of experience, reflection and epistemological application to first doing no harm, managing uncertainty, the ability to make necessary decisions while possessing incomplete information, an appreciation of complex adaptive systems, maintenance of homeostasis, vigilance for unintended consequences, and an appreciation of the importance of transdisciplinarity and interprofessionalism. Summary General practitioners have a long history of public health advocacy and in the case of climate change may bring a way of approaching complex human problems that could be applied to the dilemmas of climate change.

    Patients usually get medical assistance in several clinics and hospitals during their lifetime, archiving vital information in a dispersed way. Clearly, a proper patient care should take into account that information in order to check for incompatibilities, avoid unnecessary exams, and get relevant clinical history. The Heart Institute (InCor) of São Paulo, Brazil, has been committed to the goal of integrating all exams and clinical information within the institution and other hospitals. Since InCor is one of the six institutes of the University of São Paulo Medical School and each institute has its own information system, exchanging information among the institutes is also a very important aspect that has been considered. In the last few years, a system for transmission, archiving, retrieval, processing, and visualization of medical images integrated with a hospital information system has been successfully created and constitutes the InCor's electronic patient record (EPR). This work describes the experience in the effort to develop a functional and comprehensive EPR, which includes laboratory exams, images (static, dynamic, and three dimensional), clinical reports, documents, and even real-time vital signals. A security policy based on a contextual role-based access control model was implemented to regulate user's access to EPR. Currently, more than 10 TB of digital imaging and communications in medicine (DICOM) images have been stored using the proposed architecture and the EPR stores daily more than 11 GB of integrated data. The proposed storage subsystem allows 6 months of visibility for rapid retrieval and more than two years for automatic retrieval using a jukebox. This paper addresses also a prototype for the integration of distributed and heterogeneous EPR. PMID:17249400

    Full Text Available Abstract Background There has been an increased interest in recruiting health professionals with a clinical background to management positions in health care. We know little about the factors that influence individuals’ decisions to engage in management. The aim of this study is to explore clinicians’ journeys towards management positions in hospitals, in order to identify potential drivers and barriers to management recruitment and development. Methods We did a qualitative study which included in-depth interviews with 30 clinicians in middle and first-line management positions in Norwegian hospitals. In addition, participant observation was conducted with 20 of the participants. The informants were recruited from medical and surgical departments, and most had professional backgrounds as medical doctors or nurses. Interviews were analyzed by systemic text condensation. Results We found that there were three phases in clinicians’ journey into management; the development of leadership awareness, taking on the manager role and the experience of entering management. Participants’ experiences suggest that there are different journeys into management, in which both external and internal pressure emerged as a recurrent theme. They had not anticipated a career in clinical management, and experienced that they had been persuaded to take the position. Being thrown into the position, without being sufficiently prepared for the task, was a common experience among participants. Being left to themselves, they had to learn management “on the fly”. Some were frustrated in their role due to increasing administrative workloads, without being able to delegate work effectively. Conclusions Path dependency and social pressure seems to influence clinicians’ decisions to enter into management positions. Hospital organizations should formalize pathways into management, in order to identify, attract, and retain the most qualified talents. Top managers

  2. Occult hepatitis B virus infection: A complex entity with relevant clinical implications

    Institute of Scientific and Technical Information of China (English)

    Juan Ramon Larrubia

    2011-01-01

    Occult hepatitis B virus (HBV) infection is a world-wide entity, following the geographical distribution of detectable hepatitis B. This entity is defined as the persistence of viral genomes in the liver tissue and in some instances also in the serum, associated to negative HBV surface antigen serology. The molecular basis of the occult infection is related to the life cycle of HBV, which produces a covalently closed circular DNA that persists in the cell nuclei as an episome, and serves as a template for gene transcription. The mechanism responsible for the HBsAg negative status in occult HBV carriers is a strong suppression of viral replication, probably due to the host's immune response, co-infection with other infectious agents and epigenetic factors. There is emerging evidence of the potential clinical relevance of occult HBV infection, since this could be involved in occult HBV transmission through orthotopic liver transplant and blood transfusion, reactivation of HBV infection during immunosuppression, impairing chronic liver disease outcome and acting as a risk factor for hepatocellular carcinoma. Therefore it is important to bear in mind this entity in cryptogenetic liver diseases, hepatitis C virus/HIV infected patients and immunosupressed individuals.It is also necessary to increase our knowledge in this fascinating field to define better strategies to diagnose and treat this infection.

    2004-08-01

    Full Text Available Epstein-Barr virus (EBV, or human herpesvirus 4 (HHV-4, infects the vast majority of adults worldwide, and establishes both nonproductive (latent and productive (lytic infections. Host immune responses directed against both the lytic and latent cycle-associated EBV antigens induce a diversity of clinical symptoms in patients with chronic active EBV infections who usually contain an oligoclonal pool of EBV-infected lymphocyte subsets in their blood. Episomal EBV genes in the latent infection utilize an array of evasion strategies from host immune responses: the minimized expression of EBV antigens targeted by host cytotoxic T lymphocytes (CTLs, the down-regulation of cell adhesion molecule expression, and the release of virokines to inhibit the host CTLs. The oncogenic role of latent EBV infection is not yet fully understood, but latent membrane proteins (LMPs expressed during the latency cycle have essential biological properties leading to cellular gene expression and immortalization, and EBV-encoded gene products such as viral interleukin-10 (vIL-10 and bcl-2 homologue function to survive the EBV-infected cells. The subsequent oncogenic DNA damage may lead to the development of neoplasms. EBV-associated NK/T cell lymphoproliferative disorders are prevalent in Asia, but quite rare in Western countries. The genetic immunological background, therefore, is closely linked to the development of EBV-associated neoplasms.

    Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem. PMID:26391432

    Candida species are the most common causes of invasive fungal infections in humans, producing infections that range from mucocutaneous disorders to invasive disease that can involve any organ. Here we present our clinical experience with anidulafungin for the treatment of documented nosocomial candidaemia. From february 2009 through January 2010 all patients with documented candidemia treated with anidulafungin in three medical centers in italy were reviewed. Demographics, clinical and microbiological data, and outcome were collected for each patient. Twenty-four patients were included in the study. most patients had a central venous catheter (CVC) or a port-a-cath (100%), had a history of recent surgery (87.5%), or were receiving total parenteral nutrition (79%), broad spectrum antibiotics (83%), steroids or chemotherapy (45.8%). C. albicans (54%) was the most commonly isolated pathogen. CVC was the source of candidemia in 79% of cases. Six patients (25%) developed severe sepsis or septic shock, and five patients had unfavorable outcomes, with an overall mortality rate of 20%. No patients experienced side effects related to anidulafungin therapy. Anidulafungin was effective in the treatment of patients with documented candidemia arising from different sites, and no significant side effects were observed. PMID:21303747

    Full Text Available Background: Vaginitis is a commonly encountered complaint and one of the most frequent reasons for patient visit to obstetrician-gynaecologists. Three vaginal infections are frequent causes of a vaginal discharge: (1 bacterial vaginosis, (2 vulvovaginal candidiasis and (3 trichomonas vaginitis. Differences in the clinical presentation are helpful in diagnosis. Characteristic signs and symptoms for these three vaginal infections are distinct, but on many occasions, they are overlapping. The aim of the present study was to find the prevalence and correlation between the clinical spectrum and laboratory evidence of Trichomonas vaginalis infection by simple, reliable, confirmatory and specific method, i.e. microscopic examination of wet mount preparation and acridine stain of vaginal fluid. Materials and Methods: Irrespective of HIV status, a total of 156 women with vaginal discharge were studied for establishing diagnosis of genital tract infection. The cases of bacterial vaginosis and vulvovaginal candidiasis were excluded from the study. Vaginal speculum assisted high vaginal swabs were collected from women with discharge, during collection vagina was inspected for obvious signs. Results: Of the 156 women with vaginal discharge, 19 (12.06 % showed T. vaginalis infection. All the women belonged to active reproductive age group, i.e. 20-40 years. Itching dysuria, and offensive, malodorous, thin, yellowish vaginal discharge were the main and consistent complaints. Only in 2 (1.52% cases, vaginal speculum examination revealed erythema and punctuate haemorrhage, the so-called "strawberry′ vagina. The pH was recorded to be >4.5. Conclusion: Clinical differentiation of various forms of infectious vaginitis is unreliable. The prevalence of T. vaginalis infection at 12.06% was found among rural young women of reproductive age using simple and reliable screening wet mount microscopy.

    Full Text Available [english] Aim: Compliance with infection control practices is the key to quality care and excellence in dentistry. Infection control remains one of the most cost-beneficial interventions available. However, implementing control procedures requires full compliance of the whole dental team. The aim of our study was to measure the compliance in daily clinical practice.Methods: The compliance with infection control practices in dentistry by dental health care personnel (DHCP in a German university dental clinic was observed during clinical work. In addition, a survey was conducted to assess the individual knowledge about infection control procedures. Contamination of the workplace during invasive dental procedures was tested, as well.Results: A total of 58 invasive dental treatments implying close contacts between HCWs and patients were scrutinized. All HCWs (100% wore gloves during dental work, but in some cases (female dentists: 14.3%; dental assistants: 28.6% gloves were neither changed nor hands were disinfected between different activities or patient contacts (female dentists: 68.6%; male dentists: 60.9%; dental assistants: 93%. Only 31.4% of female and 39.1% of male dentists carried out adequate hygienic hand disinfection after removing gloves. Male dentists wore significantly more often (100% protective eyewear compared to 77.1% of female dentists (p<0.05. In addition, most of female dentists (62.9% and dental assistants (80.7% wore jewelry during dental procedures. Conclusion: Despite the knowledge of distinct hygiene procedures only a small percentage of dental staff performs hygiene practices according to recommended guidelines. Strict audit is clearly needed in the dental setting to ensure compliance with infection control guidelines to prevent transmission of pathogens. Our results provide insights for the development of a targeted education and training strategy to enhance compliance of dental staff especially of dental assistants with

    Horizontal violence is a form of workplace violence, a phenomenon that is prevalent in the nursing profession. Research has revealed a variety of negative peer-to-peer behaviors that lower morale and lead to turnover. However, little research has been conducted on "eating our young" (violence occurring between individuals with unequal power, such as staff nurse and student). We propose "vertical violence" as the appropriate term when abusive registered nurse (RN) behavior is directed towards students. We report a content analysis of stories written by junior nursing students about incidents of injustice perpetrated by staff RNs during their clinical experiences. Four levels of injustice were described. Nursing leadership, both in hospitals and educational institutions, must become engaged in efforts to eradicate vertical violence towards students.

    Human bocavirus (HBoV) is a new parvovirus associated with acute respiratory tract infection (ARTI). In order to evaluate HBoV significance as an agent of acute respiratory disease, we screened 1,135 respiratory samples from children and adults with and without symptoms during two complete calendar years. HBoV1 prevalence in patients with ARTI was 6.33 % in 2011 and 11.64 % in 2012, including neonatal and adult patients. HBoV1 was also detected in 3.77 % of asymptomatic individuals. The co-detection rate was 78.1 %. Among children, 87 % were clinically diagnosed with lower respiratory infection (no significant differences between patients with and without coinfection), and 31 % exhibited comorbidities. Pediatric patients with comorbidities were significantly older than patients without comorbidities. Patients with ARTI had either high or low viral load, while controls had only low viral load, but there were no clinical differences between patients with high or low viral load. In conclusion, we present evidence of the pathogenic potential of HBoV1 in young children with ARTI. Since patients with HBoV1-single infection are not significantly different from those with coinfection with respect to clinical features, the virus can be as pathogenic by itself as other respiratory agents are. Furthermore, an association between high HBoV1 load and disease could not be demonstrated in this study, but all asymptomatic individuals had low viral loads. Also, children with comorbidities are susceptible to HBoV1 infection at older ages than previously healthy children. Thus, the clinical presentation of infection may occur depending on both viral load and the particular interaction between the HBoV1 and the host. PMID:25269520

    Dasatinib was approved for the treatment of chronic phase (CP) chronic myeloid leukemia (CML) patients in first line therapy based on the demonstration of efficacy and safety reported in patients enrolled in clinical trials. We describe a multicentric Italian "real-life" experience of dasatinib used as frontline treatment outside clinical trials. One hundred and nine patients (median age 54 years) were treated from January 2012 to December 2013. Increased incidence of high risk patients were detected according to stratification (26% according to Sokal score, 19% according to Euro score and 16% according to EUTOS) when compared to company sponsored studies. Median time from diagnosis to start of dasatinib was 18 days. Ten patients received unscheduled starting dose (6 patients 50mg and 4 patients 80 mg QD), whereas 99 patients started with 100mg QD. At 3 months, 92% of patients achieved a BCR-ABL ratio less than 10%. At 6 months, the rate of CCyR was 91% and the rate of MR3 was 40%, with 8% of the patients reaching MR4.5. Ninety-three patients were evaluable at 12 months: the rate of MR3 was 62%, with MR4.5 being achieved by 19% of the patients. At a median follow-up of 12 months, 27 patients (24.7%) were receiving the drug at reduced dose. Two patients (1.8%) experienced a lymphoid blast crisis and the overall incidence of resistance was 8%. As regards safety, the major side effects recorded were thrombocytopenia, neutropenia and pleural effusions, which occurred in 22%, 10% and 8% of patients, respectively. Present results, achieved in a large cohort of patients treated outside clinical trials, further confirm the efficacy and safety of dasatinib as firstline treatment in CML. PMID:26643920

We retrospectively included patients starting dabigatran etexilate for secondary stroke prevention from March 2010 to December 2012. Efficacy and safety variables were registered. Results. 106 patients were included, median follow-up of 12 months (range 1–31. Fifty-six females (52.8%, mean age 76.4 (range 50–95, SD 9.8, median CHADS2 4 (range 2–6, CHA2DS2-VASc 5 (range 2–9, and HAS-BLED 2 (range 1–5. Indication for dabigatran etexilate was ischemic stroke in 101 patients and acute cerebral hemorrhage (CH due to warfarin in 5 (4.7%. Dabigatran etexilate 110 mg bid was prescribed in 71 cases (67% and 150 mg bid was prescribed in the remaining. Seventeen patients (16% suffered 20 complications during follow-up. Ischemic complications (10 were 6 transient ischemic attacks (TIA, 3 ischemic strokes, and 1 acute coronary syndrome. Hemorrhagic complications (10 were CH (1, gastrointestinal bleeding (6, mild hematuria (2, and mild metrorrhagia (1, leading to dabigatran etexilate discontinuation in 3 patients. Patients with previous CH remained uneventful. Three patients died (pneumonia, congestive heart failure, and acute cholecystitis and 9 were lost during follow-up. Conclusions. Dabigatran etexilate was safe and effective in secondary stroke prevention in clinical practice, including a small number of patients with previous history of CH.

  17. Antioxidant vitamins in atherosclerosis--animal experiments and clinical studies.

    Atherosclerotic heart diseases are universal problems in modern society. Oxidative damage to lipids is a primary cause of atherosclerosis. There are many choices for treatment, but no definite recommendations to prevent the occurrence of the disease. There is a relationship between atherosclerotic risk factors and increased vascular production of reactive oxygen species (ROS). Oxidized low-density lipoproteins (LDL) and ROS may directly cause endothelial dysfunction by reducing endothelial nitric oxide (NO) bioavailability. Vitamin E can to some degree prevent the consequences of oxidized LDL, and vitamin C provides NO synthase activity. Although prolonged use of vitamin A, C, and E supplementation in pharmaceutical forms has been proven to be effective in preventing atherosclerosis in animal experiments, this has not yet been demonstrated in clinical trials with human beings. It should be taken into account that the evidence has been gathered from young/adult experimental animals with early stages of arthrosclerosis and from in-vitro studies, while most of the clinical trials have involved older patients with late stages of the disease. Prolonged use of vitamins in the diet has not yet been recommended in human beings. There is some indication that a diet rich in antioxidant fruit and vegetables may be beneficial in the prevention of cardiovascular events. PMID:23214308

    Maraviroc (MVC) is not approved for HIV-1-infected paediatric patients. This is the first assessment of the use of MVC-based salvage therapy in vertically HIV-1-infected paediatric patients in clinical settings. The results suggest that MVC-based salvage therapy is useful in children and adolescents with extensive resistance profile leading to maintained virological suppression in up to 88% of the patients with CCR5-tropic virus. The likelihood of treatment success might increase when MVC is combined with other active drugs. PMID:26544580

  4. Clinical evaluation of technetium-99m infecton for the localisation of bacterial infection

    International Nuclear Information System (INIS)

    The aim of the study was to distinguish infection from inflammation in patients with suspected infection using technetium-99m Infecton. Ninety-nine patients (102 studies) referred for infection evaluation underwent imaging with 400 MBq 99mTc-Infecton at 1 and 4 h. Most patients had appropriate microbiological tests and about half (56) had radiolabelled white cell scans as well. No adverse effects were noted in any patient. The clinical efficacy of 99mTc-Infecton depended in part on whether imaging was undertaken during antibiotic therapy for infection or not. In consultation with the microbiologist, 5-14 days of appropriate and successful antibiotic therapy was considered adequate to classify some results as true-negatives. The figures for sensitivity and specificity of 99mTc-Infecton for active or unsuccessfully treated infection were 83% and 91% respectively. It is concluded that 99mTc-Infecton imaging contributed to the differential diagnosis of inflammation. It is being used as the first imaging modality when bacterial infection is suspected. (orig.).

    We studied 35 pediatric patients with autoimmune hemolytic anemia seen at Mayo Clinic from 1994 to 2014. The median age was 10.0 years and 65.7% were males. Most had warm antibodies (80.0%) and some secondary to viral (14.3%) or autoimmune disorders (31.4%). Seven (20.0%) patients presented with Evans syndrome, 3 of whom also had common variable immunodeficiency. The median hemoglobin at diagnosis was 6.1 g/dL and 62.8% patients required red cell transfusions. The severity of anemia was worse among children below 10 years (median 5.5 vs. 7.0 g/dL, P=0.01). Steroid was the initial treatment for 88.5% patients, with overall response rate of 82.7% (68.5% complete, 14.2% partial) and median response duration of 10.7 months (range, 0.2 to 129.7+ mo). After median follow-up of 26.6 months, 8 (22.8%) patients relapsed. Salvage treatments included splenectomy, intravenous immunoglobulin, rituximab, and mycophenolate mofetil. Infectious complications occurred in 9 (25.7%) patients and 1 patient died of cytomegalovirus infection. Four patients had cold agglutinin disease and 3 (75.0%) responded to steroids. Autoimmune hemolytic anemia is a rare disorder in pediatric population and most respond well to steroids regardless of the type of antibody. Infectious complications are common and screening for immunodeficiency is recommended among those with Evans syndrome. PMID:26925716

    Background Although heart transplantation has become a standard therapy for end-stage heart disease, there are few published studies regarding the use of transplant organs from marginal donors. Here we describe the clinical outcome we have obtained using marginal donor hearts.Methods We analyzed 21 cases of orthotropic heart transplantation for end-stage heart disease performed in our department between September 2008 and July 2010. Of these patients, six received hearts from marginal donors and the remainder received standard-donor hearts. The two groups were compared in terms of both mortality and the incidence of perioperative complications such as infection, acute rejection, and right heart insufficiency.Results The 1-year survival rate of both groups was 100%. Only one death was recorded in standard-donor group during follow-up. Patients who received marginal donor hearts (83%) experienced more early complications than did the standard-donor-heart group (13%), but the mortality of the two groups was the same. The duration of post-ICU stay was greater in the marginal donor group than in the standard-donor group, (35.5±17.4) days and (21.7±2.6) days, respectively (P <0.05).Conclusions The use of marginal donor hearts increases the number of patients who can receive and benefit from transplants. However, it may introduce an increased risk of early complications, thus care should be taken both in the choice of patients who will receive marginal donor hearts and in the perioperative treatment of those for whom the procedure is performed.

  12. Non-invasive prenatal chromosomal aneuploidy testing--clinical experience: 100,000 clinical samples.

    Directory of Open Access Journals (Sweden)

    Ron M McCullough

    Full Text Available OBJECTIVE: As the first laboratory to offer massively parallel sequencing-based noninvasive prenatal testing (NIPT for fetal aneuploidies, Sequenom Laboratories has been able to collect the largest clinical population experience data to date, including >100,000 clinical samples from all 50 U.S. states and 13 other countries. The objective of this study is to give a robust clinical picture of the current laboratory performance of the MaterniT21 PLUS LDT. STUDY DESIGN: The study includes plasma samples collected from patients with high-risk pregnancies in our CLIA-licensed, CAP-accredited laboratory between August 2012 to June 2013. Samples were assessed for trisomies 13, 18, 21 and for the presence of chromosome Y-specific DNA. Sample data and ad hoc outcome information provided by the clinician was compiled and reviewed to determine the characteristics of this patient population, as well as estimate the assay performance in a clinical setting. RESULTS: NIPT patients most commonly undergo testing at an average of 15 weeks, 3 days gestation; and average 35.1 years of age. The average turnaround time is 4.54 business days and an overall 1.3% not reportable rate. The positivity rate for Trisomy 21 was 1.51%, followed by 0.45% and 0.21% rate for Trisomies 18 and 13, respectively. NIPT positivity rates are similar to previous large clinical studies of aneuploidy in women of maternal age ≥ 35 undergoing amniocentesis. In this population 3519 patients had multifetal gestations (3.5% with 2.61% yielding a positive NIPT result. CONCLUSION: NIPT has been commercially offered for just over 2 years and the clinical use by patients and clinicians has increased significantly. The risks associated with invasive testing have been substantially reduced by providing another assessment of aneuploidy status in high-risk patients. The accuracy and NIPT assay positivity rate are as predicted by clinical validations and the test demonstrates improvement in the

    The excretion rate of (3H)prednisolone from clinically normal and experimentally infected udders of 10 lactating cows was studied. Each quarter of 6 cows was injected with a single dose of (3H)prednisolone mixed with non-radioactive prednisolone equivalent to 10 mg in 10 ml of peanut oil base. Each of the remaining 4 cows was given 40 mg of nonradioactive prednisolone and (3H)prednisolone in 60% ethanol IV. Control and postadministration samples of blood, milk, and urine were examined for radioactivity. The effects of (3H)prednisolone were evaluated in the same cows, first in clinically normal udders, then 2 weeks later in udders experimentally infected with Streptococcus agalactiae. Absorption and elimination of prednisolone were the same before and after induced infection. Within 3 hours after intramammary injection, 95% of the labeled prednisolone was absorbed systemically, less than 5% of this dose was recovered in milk, and 29% was excreted in urine. After IV injection of (3H)prednisolone, less than 0.2% of the total radioactivity was recovered in milk and less than 46% was excreted in urine. Clinical mastitis induced by S agalactiae was moderate. Circulating blood leukocytes and somatic cells in the milk of normal cows remained essentially unchanged. The leukocyte response to induced infection was rapid in blood and milk. Large numbers of leukocytes were noticed in the milk and a severe leukopenia occurred. Prednisolone treatment did not alter the number of somatic cells in milk or reduce the inflammatory response of experimentally infected cows.

    Full Text Available INTRODUCTION: Dengue viral infections are among the most important mosquito-borne diseases of the Indian subcontinent and have become a major global public health concern. Spread of disease has led to increased recognition of atypical manifestations, apart from the classical clinical features of dengue infection. METHODOLOGY: This case study was conducted at the department of Pediatrics in collaboration with the Microbiology Department of Dr. Ulhas Patil Medical College, Jalgaon District of Maharashtra in West India during the period of 2 years from July 2012 to June 2014. Clinically suspected and serologically confirmed cases of dengue fever were included in the study. Clinical and biochemical parameters were compared between the two groups of dengue fever and dengue hemorrhagic fever. RESULTS: 247 patients clinically suspected and serologically confirmed cases of dengue infection were enrolled in the study. One sixty one (65% patients were males and 86 (35% were females. One seventy three (70% patients had a classical dengue fever while 74 (30% had dengue hemorrhagic fever. The most common symptoms were headache (212, 86%, skin rash (163, 66%, abdominal pain (131, 53%, vomiting (119, 48%, and hemorrhagic manifestations were present in 84 (34% patients. Atypical manifestations were recorded. Notably, 9% of patients had neurological involvement and 5% had multi-organ failure. Overall mortality was 4.5%. CONCLUSION: Dengue infection poses a huge burden to the healthcare system; its spectrum ranges from mild self-limiting illness to severe fatal disease. It can have varied and multi-systemic manifestations which can go unrecognized. Deaths occurred in 55% (6/11 cases were associated with dengue neurological manifestations needs support to the clinicians should have a high index of suspicion for atypical manifestations in dengue endemic countries.

    Abstract Background Chronic wounds affect millions of people and cost billions of dollars in the United States each year. These wounds harbor polymicrobial biofilm communities, which can be difficult to elucidate using culturing methods. Clinical molecular microbiological methods are increasingly being employed to investigate the microbiota of chronic infections, including wounds, as part of standard patient care. However, molecular testing is more sensitive than culturing, which results in m...

    Infectious epididymitis is considered a major cause of economic losses for the sheep industry worldwide. This study aimed to investigate clinical and pathological changes associated with experimental infections with A. seminis and H. somni in rams. Twenty rams of age 18 to 24 months were infected by intraepididymal inoculation of A. seminis (n = 10) and H. somni (n = 10). Rams were weekly examined and biological samples were collected during six weeks. All rams inoculated with A. seminis and 80% inoculated with H. somni became infected. The recovery of bacteria was possible in semen and urine samples and tissues in both experimental groups. Clinically, there were a decrease in testicular consistency and an increase in measures of the left epididymis tails in both experimental groups. The main gross changes were observed in the reproductive tract. Microscopically, the main lesions were inflammatory changes in the genitourinary tract and testicular degeneration. A. seminis and H. somni were able to colonize several organs of the genitourinary tract in rams, being indistinguishable by clinical exam, necropsy or histopathology. For differential diagnosis, it is important to use diagnostic techniques for direct confirmation of the etiologic agent. PMID:24592151

    Full Text Available Introduction Surgical site infections (SSIs can affect body tissues, cavities, or organs manipulated in surgery and constitute 14% to 16% of all infections. This study aimed to determine the incidence of SSIs in women following their discharge from a gynecology outpatient clinic, to survey different types of SSIs among women, and to verify the association of SSIs with comorbidities and clinical conditions. Methods Data were collected via analytical observation with a cross-sectional design, and the study was conducted in 1,026 women who underwent gynecological surgery in a teaching hospital in the municipality of Teresina, in the northeast Brazilian State of Piauí, from June 2011 to March 2013. Results The incidence of SSIs after discharge was 5.8% among the women in the outpatient clinic. The most prevalent surgery among the patients was hysterectomy, while the most prevalent type of SSI was superficial incisional. Comorbidities in women with SSIs included cancer, diabetes mellitus, and hypertension. Conclusions Surveillance of SSIs during the post-discharge period is critical for infection prevention and control. It is worth reflecting on the planning of surgical procedures for patients who have risk factors for the development of SSIs.

    During the period 1973-1984, 72 patients with infective endocarditis (IE) were hospitalized in the medical department, Bergen University Hospital. The male/female ratio was 1.25/1, the mean age 55.3 years. 35 infections were caused by streptococci, 18 by staphylococci, 6 by other microorganisms and in 13 cases no causal organism was found. Only 13 patients had rheumatic heart disease. The overall mortality was 35%, and the mean age of the patients who died was 65 years. The case fatality rates for staphylococcal and streptococcal endocarditis were 61 and 24% respectively. In the period 1973-1978 the case fatality rate was 50% compared to 26% during 1979-1984. The proportion of patients with culture-negative endocarditis was reduced from 31 to 11% from the first to the second half of the study and the percentage of patients who received antibiotics before diagnosis decreased from 81 to 58%. Valve replacement was performed in 4 patients with staphylococcal and 15 with streptococcal infections. Seven cases (mean age 73.4 years) were diagnosed at necropsy; 3 with staphylococcal infections. With increased clinical awareness of IE, liberal use of blood cultures, better diagnostic tools and earlier surgical intervention, especially in staphylococcal infections, a further reduction in mortality should be possible.

    Full Text Available Respiratory tract infections are a common complaint and most of them, such as common cold and laryngitis, are viral in origin, so antibiotic use should be exceptional. However, there are other respiratory tract infections (sinusitis, pharyngitis, lower respiratory tract infections, and exacerbations of chronic obstructive pulmonary disease where a bacterial etiology is responsible for a non-negligible percentage, and antibiotics are often empirically indicated. The aim of the study is to identify the strength of the data obtained from the symptoms, physical examination and rapid diagnostic methods in respiratory infections in which antibiotic use is frequently proposed in order to improve diagnosis and influence the decision to prescribe these drugs. The review concludes that history, physical examination and rapid tests are useful to guide the need for antibiotic treatment in diseases such as acute sinusitis, acute pharyngitis, exacerbation of lower respiratory tract infection and chronic obstructive pulmonary disease. However, no isolated data is accurate enough by itself to confirm or rule out the need for antibiotics. Therefore, clinical prediction rules bring together history and physical examination, thereby improving the accuracy of the decision to indicate or not antibiotics.

    Full Text Available Staphylococcus (S. aureus and Pseudomonas (Ps. aeruginosa are two of the most frequently opportunistic pathogens isolated in nosocomial infections, responsible for severe infections in immunocompromised hosts. The frequent emergence of antibiotic-resistant S. aureus and Ps. aeruginosa strains has determined the development of new strategies in order to elucidate the different mechanisms used by these bacteria at different stages of the infectious process, providing the scientists with new procedures for preventing, or at least improving, the control of S. aureus and Ps. aeruginosa infections. The purpose of this study was to characterize the molecular markers of virulence in S. aureus and Ps. aeruginosa strains isolated from different clinical specimens. We used multiplex and uniplex PCR assays to detect the genes encoding different cell-wall associated and extracellular virulence factors, in order to evaluate potential associations between the presence of putative virulence genes and the outcome of infections caused by these bacteria. Our results demonstrate that all the studied S. aureus and Ps. aeruginosa strains synthesize the majority of the investigated virulence determinants, probably responsible for different types of infections.

    Full Text Available Clinical relevance of infection with different Helicobacter pylori strains was reviewed in this paper. Helicobacter pylori (H. pylori infection plays a role in pathogenesis of chronic gastritis, peptic ulcer disease, gastric adenocarcinoma and MALT lymphoma. Extragastric manifestations of H. pylori infection most probably include acne rosacea and chronic urticaria, while the importance of H. pylori infection for pathogenesis of growth retardation in children, iron deficiency anemia, coronary heart disease, stroke and idiopathic thrombocytopenic purpura remains vague. The expression of two H. pylori proteins, cytotoxin associated protein (cag A and vacuolization cytotoxin (vac A is considered to be related with pathogenicity of the bacterium. It is clear that presence of cag A+ strains is important for development of peptic ulcer; nevertheless, it is also protective against esophageal reflux disease. On the other hand, cag A+ strains are common in gastric adenocarcinoma and MALT lymphoma patients, but it seems that certain subtypes of vac A cytotoxin are more important risk factors. Infection with cag A+ strains is more common in patients with acne rosacea, stroke and coronary heart disease.

    Full Text Available Abstract Background We conducted a nationwide study in Denmark to identify clinical features and prognostic factors in patients with Streptococcus pneumoniae according to the focus of infection. Methods Based on a nationwide registration, clinical information's was prospectively collected from all reported cases of pneumococcal meningitis during a 2-year period (1999–2000. Clinical and laboratory findings at admission, clinical course and outcome of the disease including follow-up audiological examinations were collected retrospectively. The focus of infection was determined according to the clinical diagnosis made by the physicians and after review of the medical records. Results 187 consecutive cases with S. pneumoniae meningitis were included in the study. The most common focus was ear (30%, followed by lung (18%, sinus (8%, and other (2%. In 42% of cases a primary infection focus could not be determined. On admission, fever and an altered mental status were the most frequent findings (in 93% and 94% of cases, respectively, whereas back rigidity, headache and convulsion were found in 57%, 41% and 11% of cases, respectively. 21% of patients died during hospitalisation (adults: 27% vs. children: 2%, Fisher Exact Test, P P = 0.0005. Prognostic factors associated with fatal outcome in univariate logistic regression analysis were advanced age, presence of an underlying disease, history of headache, presence of a lung focus, absence of an otogenic focus, having a CT-scan prior to lumbar puncture, convulsions, requirement of assisted ventilation, and alterations in various CSF parameters (WBC P P = 0.005. Conclusion These results emphasize the prognostic importance of an early recognition of a predisposing focus to pneumococcal meningitis.

    Full Text Available BACKGROUND : Acute respiratory infections are a leading cause of morbidity and mortality in under - five children in developing countries. Hence, the present study was undertaken to study the various risk factors, clinical profile and outcome of acute lower respiratory tract infections (ALRI in children aged 2 month to 5 years. OBJECTIVE : clinical features, laborato ry assessment and morbidity and mortality pattern associated with acute lower respiratory tract infections in children aged 2 months to 5 years. METHODS: 100 ALRI cases fulfilling WHO criteria for pneumonia, in the age group of 2 month to 5 years were evaluated for clinical profile as per a predesigned proforma in a rural medical college. RESULTS : Of cases 61% were infants and remaining 39%12 - 60 months age group, males outnumbered females with sex ratio of 1.3;1. Elevated total leukocyte counts for age were observed in only 22% of cases, of these 3% were having pneumonia, 9% severe pneumonia and 10% very severe pneumonia. Significant association was found between leukocytosis and ALRI severity (p= 0.0001 Positive blood culture was obtained in 8% of cases and was significantly associated with ALRI severity (p=. 0.027. Among the ALRI cases, 84% required oxygen supplementation at any time during the hospital stay and 8% required mechanical ventilation. The mortality rate was 1%; with 99% of cases recovering and getting discharged uneventfully. CONCLUSION : Among the clinical variables, the signs and symptoms of ALRI as per the WHO ARI Control Programme were found in almost all cases. Regarding the laboratory profile, leukocytosis and blood culture positivity w ere observed in a small percentage, but significant association with ALRI severity was observed for both. Thus, clinical signs, and not invasive blood tests are a better diagnostic tools, though the latter may provide additional therapeutic and prognostic information in severe disease

    Full Text Available BACKGROUND: Perianal infection is a common problem for patients with acute leukemia. However, neutropenia and bleeding tendency are relatively contraindicated to surgical intervention. The epidemiology, microbiology, clinical manifestations and outcomes of perianal infection in leukemic patients are also rarely discussed. METHOD: The medical records of 1102 adult patients with acute leukemia at a tertiary medical center in Taiwan between 2001 and 2010 were retrospectively reviewed and analyzed. RESULT: The prevalence of perianal infection was 6.7% (74 of 1102 in adult patients with acute leukemia. Twenty-three (31% of the 74 patients had recurrent episodes of perianal infections. Patients with acute myeloid leukemia had higher recurrent rates than acute lymphoblastic leukemia patients (p = 0.028. More than half (n = 61, 53% of the perianal infections were caused by gram-negative bacilli, followed by gram-positive cocci (n = 36, 31%, anaerobes (n = 18, 15% and Candida (n = 1, 1% from pus culture. Eighteen patients experienced bacteremia (n = 24 or candidemia (n = 1. Overall 41 (68% of 60 patients had polymicrobial infection. Escherichia coli (25% was the most common micro-organism isolated, followed by Enterococcus species (22%, Klebsiella pneumoniae (13%, and Bacteroides species (11%. Twenty-five (34% of 74 patients received surgical intervention. Acute leukemia patients with surgically managed anal fistulas tended to have fewer recurrences (p = 0.067. Four (5% patients died within 30 days after diagnosis of perianal infection. Univariate analysis of 30-day survival revealed the elderly (≧ 65 years (p = 0.015 and patients with shock (p<0.001 had worse outcome. Multivariate analysis showed septic shock to be the independent predictive factor of 30-day crude mortality of perianal infections (p = 0.016.

    Biological wound dressings sterilized with gamma radiation, such as amnion and pig skin, are a reality in Mexico. These tissues are currently processed in the tissue bank and sterilized in the Gamma Industrial Irradiation Plant; both facilities belong to the Instituto Nacional de Investigaciones Nucleares (ININ) (National Institute of Nuclear Research). With the strong support of the International Atomic Energy Agency, the bank was established at the ININ and the Mexican Ministry of Health issued its sanitary license on July 7, 1999. The Quality Management System of the bank was certified by ISO 9001:2000 on August 1, 2003; the scope of the system is "Research, Development and Processing of Biological Tissues Sterilized with Gamma Radiation". At present, more than 150 patients from 16 hospitals have been successfully treated with these tissues. This paper presents a brief description of the tissue processing, as well as the present Mexican clinical experience with children and adult patients who underwent medical treatment with radiosterilized amnion and pig skin, used as biological wound dressings on burns and ocular surface disorders.

    2003-04-01

    Background: Standard treatment in patients with malignant glioma consists of surgery and postoperative radiotherapy. A high early recurrence rate, particularly in glioblastoma, has led to the investigation of additional chemotherapy. Material and Methods: Recent results of radiochemotherapy published in the literature were reviewed with respect to outcome in phase II and III trials. Based on these experiences, aspects of future strategies were discussed. Results: 3 decades of intensive research had, unfortunately, little impact on the overall results. While early prospective studies established adjuvant nitrosoureas, particularly BCNU, as suitable adjuvant to surgery and postoperative radiotherapy, further studies largely concentrated on combined chemotherapeutic protocols, mostly procarbazine, CCNU and vincristine (PCV), which was shown to prolong survival in anaplastic astrocytoma. The recent MRC study, however, showed no effect for adjuvant PCV in grade III and IV malignant glioma. Only in high-grade glioma with an oligodendroglial component, additional chemotherapy may be of a decisive benefit. The introduction of newer drugs such as paclitaxel, temozolomide, or gemcitabine demonstrated no decisive advantage. Different modes of application and sequencing of radiotherapy and chemotherapy are presently actively investigated, but failed to substantially improve outcome. Conclusions: Therefore, search for newer and more effective drugs continues, as well as for ''optimal'' administration and sequencing, especially from the standpoint of accompanying acute and late toxicity. Finally, recent endeavors focused on basic research such as angiogenesis, migration and invasion, or induction of cell differentiation, but these strategies are still away from broader clinical investigation.

    In the past decade, single photon emission computed tomography (SPECT) has evolved from an experimental technique used only in academic settings to a routine clinical examination performed in many community hospitals. Responding to reports of increased diagnostic efficacy, many nuclear medicine physicians have chosen to make SPECT imaging a routine technique for bone, liver, spleen, heart, and brain imaging. However, the enthusiasm for SPECT is not universal. Most nuclear medicine physicians continue to rely primarily on planar imaging, with little or no routine use of SPECT. This milieu has left many physicians asking themselves the following practical questions: Can SPECT be done easily in my hospital? Will not doing SPECT reduce the competitiveness of my nuclear medicine laboratory? The authors' experience at an institution heavily committed to SPECT for over 5 years may be helpful in answering these types of questions. The first rotating gamma camera at the Milwaukee Regional Medical Center was installed in late 1981. At present the authors have eight gamma cameras, of which four routinely perform SPECT examinations. Between 1981 and 1986, over 4,000 SPECT examinations have been performed

    Following the first successful heart transplant in 1967, more than 100,000 heart transplants have been carried out worldwide. These procedures have mostly relied on cold ischaemic preservation of the donor heart because this simple technique is inexpensive and relatively reliable. However, the well-known limitations of cold ischaemic preservation imposes significant logistical challenges to heart transplantation which put a ceiling on the immediate success on this life-saving therapy, and limits the number of donor hearts that can be safely transplanted annually. Although the theoretical advantages of normothermic donor heart perfusion have been recognised for over a century, the technology to transport donor hearts in this state has only been developed within the last decade. The Organ Care System (OCS) which is designed and manufactured by TransMedics Inc. is currently the only commercially available device with this capability. This article reviews the history of normothermic heart perfusion and the clinical experience with the TransMedics OCS to date. We have also attempted to speculate on the future possibilities of this innovative and exciting technology. PMID:24853906

    This hermeneutic phenomenological study explored the lived experiences of young African American HIV-infected women. Eleven women between the ages of 21 and 35 participated. One pattern, Infected Lives, and three themes--Living Alone With HIV, Living With Unresolved Conflicts, and Living With Multiple Layers of Betrayal--emerged. The pattern and themes portray the very complex and challenging experiences faced by these young women living with HIV infection. They have experienced isolation, abandonment, betrayal, and discrimination in their interpersonal and social systems. They often dealt with conflicts of hope and anguish in the relationships with their children, and portraying strength, while feeling fragile. These complexities negatively influence the ability to fully engage in self-care activities. Implications for future research include further investigation about the experiences of psychological distress experienced post-diagnosis, development and evaluation of holistic nursing interventions, and evaluative research on mass media educational campaigns to reduce HIV-related stigma.

    Noroviruses (NoVs) have emerged as the leading cause of acute viral gastroenteritis (GE) in humans. Although diagnostic facilities have greatly improved, significant underdiagnosis of NoV in hospitals may still occur, thereby increasing clinical burden and nosocomial spread. We evaluated the underdiagnosis of sporadic NoV infections in a tertiary care hospital and estimated its clinical impact. From December 2008 until July 2009, fecal samples specifically referred for bacterial but not viral examination were retrospectively tested for NoV by real-time PCR. The clinical and virological data from patients with undiagnosed NoV infection (missed patients) were evaluated and compared with those from patients with recognized NoV. During the study period, 45 patients with undiagnosed NoV were detected, whereas 50 patients were regularly diagnosed. The missed NoV cases were more frequently adults than children (80% versus 46%; P < 0.001). The viral load levels did not differ between the diagnosed and missed patients, but missed patients more frequently presented without diarrhea (20% versus 4%; P < 0.07). The newly admitted missed NoV cases with GE underwent more diagnostic imaging (24% versus 4%; P < 0.01) and tended to be hospitalized longer. When missed-NoV patients were included, the number of nosocomial clusters doubled and missed patients were index cases in 5 of the 6 clusters. These data indicate that NoV infections are frequently missed despite routine laboratory testing and demonstrate that underdiagnosis of NoV patients is associated with costly abdominal imaging and nosocomial clustering. Awareness of NoV infection in adult patients and education about the importance of viral GE should be increased. PMID:22785184

    Full Text Available BACKGROUND & OBJECTIVES: HIV infection can be monitored by laboratory and clinical markers of disease progression. In the absence of CD 4 count , the use of Total Lymphocyte Count has been advocated to predict CD 4 count and to stage HIV disease. This study was undertaken to show whether the TLC accurately predicts a low CD 4 count in HIV infected persons and its clinical correlation. METHODOLOGY: The data for the study was collected from HIV positive inpatients and outpatients of KIMS Hospital , Bangalore fr om March 2004 to March 2006. A total 50 patients were subjected to clinical examination and relevant investigations including CD 4 Count and TLC. RESULTS: In our study , males (39 , outnumbered females (11. The major risk factor for HIV infection in these patients was unprotected , multiple sexual contacts. Fever , Anorexia , Weight loss , Lethargy , Cough , Diarrhea and Mouth ulcers were the common presenting symptoms. Tuberculosis , Chronic diarrhea , Oropharyngeal candidiasis were the most common opportunistic i nfections. Majority of the patients had CD 4 Count less than 350 cells/μl and were symptomatic. The Total Lymphocyte Counts of 1750 cells/μl and 2450 cells/μl correlated to CD 4 counts of 200 cells/μl and 350 cells/μl respectively. INTERPRETATION & CONCLUS ION: There was a highly significant correlation between CD 4 Count and Total Lymphocyte Count. TLC can be used as an effective laboratory tool to monitor disease progression in HIV infected persons where CD 4 is not available and in resource poor countries .

    Prion diseases, such as bovine spongiform encephalopathies (BSE), are transmissible neurodegenerative disorders affecting humans and a wide variety of mammals. Variant Creutzfeldt-Jakob disease (vCJD), a prion disease in humans, has been linked to exposure to BSE prions. This classical BSE (cBSE) is now rapidly disappearing as a result of appropriate measures to control animal feeding. Besides cBSE, two atypical forms (named H- and L-type BSE) have recently been described in Europe, Japan, and North America. Here we describe the first wide-spectrum microarray analysis in whole blood of atypical BSE-infected cattle. Transcriptome changes in infected animals were analyzed prior to and after the onset of clinical signs. The microarray analysis revealed gene expression changes in blood prior to the appearance of the clinical signs and during the progression of the disease. A set of 32 differentially expressed genes was found to be in common between clinical and preclinical stages and showed a very similar expression pattern in the two phases. A 22-gene signature showed an oscillating pattern of expression, being differentially expressed in the preclinical stage and then going back to control levels in the symptomatic phase. One gene, SEL1L3, was downregulated during the progression of the disease. Most of the studies performed up to date utilized various tissues, which are not suitable for a rapid analysis of infected animals and patients. Our findings suggest the intriguing possibility to take advantage of whole blood RNA transcriptional profiling for the preclinical identification of prion infection. Further, this study highlighted several pathways, such as immune response and metabolism that may play an important role in peripheral prion pathogenesis. Finally, the gene expression changes identified in the present study may be further investigated as a fingerprint for monitoring the progression of disease and for developing targeted therapeutic interventions.

    Full Text Available BACKGROUND: To examine our eight year clinic-based experience in a Parkinson's disease expert clinical care center using clozapine as a treatment for refractory psychosis in Parkinson's disease (PD. METHODS: The study was a retrospective chart review which covered eight years of clozapine registry use. Statistical T-tests, chi-square, correlations and regression analysis were used to analyze treatment response for potential associations of age, disease duration, and Hoehn & Yahr (H&Y score, and degree of response to clozapine therapy. RESULTS: There were 36 participants included in the analysis (32 PD, 4 parkinsonism-plus. The characteristics included 30.6% female, age 45-87 years (mean 68.3±10.15, disease duration of 17-240 months (mean 108.14±51.13 and H&Y score of 2 to 4 (mean 2.51±0.51. The overall retention rate on clozapine was 41% and the most common reasons for discontinuation were frequent blood testing (28%, nursing home (NH placement (11% and leucopenia (8%. Responses to clozapine across the cohort were: complete (33%, partial (33%, absent (16%, and unknown (16%. Age (r = -0.36, p0.05. CONCLUSIONS: This single-center experience highlights the challenges associated with clozapine therapy in PD psychosis. Frequent blood testing remains a significant barrier for clozapine, even in patients with therapeutic benefit. Surprisingly, all patients admitted to a NH discontinued clozapine due to logistical issues of administration and monitoring within that setting. Consideration of the barriers to clozapine therapy will be important to its use and to its continued success in an outpatient setting.

    Full Text Available Background. Understanding HIV-infected patient experiences and perceptions of reproductive counseling in the health care context is critical to inform design of effective pharmaco-behavioral interventions that minimize periconception HIV risk and support HIV-affected couples to realize their fertility goals. Methods. We conducted semistructured, in-depth interviews with 30 HIV-infected women (with pregnancy in prior year and 20 HIV-infected men, all reporting serodiscordant partners and accessing care in Durban, South Africa. We investigated patient-reported experiences with safer conception counseling from health care workers (HCWs. Interview transcripts were reviewed and coded using content analysis for conceptual categories and emergent themes. Results. The study findings indicate that HIV-infected patients recognize HCWs as a resource for periconception-related information and are receptive to speaking to a HCW prior to becoming pregnant, but seldom seek or receive conception advice in the clinic setting. HIV nondisclosure and unplanned pregnancy are important intervening factors. When advice is shared, patients reported receiving a range of information. Male participants showed particular interest in accessing safer conception information. Conclusions. HIV-infected men and women with serodiscordant partners are receptive to the idea of safer conception counseling. HCWs need to be supported to routinely initiate accurate safer conception counseling with HIV-infected patients of reproductive age.

    Full Text Available Purpose: to evaluate epidemiologic situation as to meningococcal infection and reveal clinical-epidemiological features of the disease on the territory of Krasnoyarsk сity and Krasnoyarsk Krai at the present stage. Data and methods: The research gives the analysis of MI morbidity and mortality rates in children of the region according to official information from the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in Krasnoyarsk Krai for the period 2000–2014. The work studies clinical and epidemiological features of the disease in 53 patients with the generalized form of meningococcal infection (GFMI who were treated in the infectious disease department of the Regional Interdistrict Children’s Clinical Hospital of Krasnoyarsk for the period 2010–2014. Results: The epidemiological situation as to MI in Krasnoyarsk for the period 2000-2013 years is characterized by the signs of interepidemic period with morbidity rises in the winter-spring period. Children from 1 year to 3 years (54,7% prevail over all MI diseased. The number of children in the first year of life decreased almost two times (from 40% to 20,7%. At the same time the proportion of children older than 4 years increased. The leading serotype among laboratory-confirmed cases of MI in Krasnoyarsk Krai is still the B group meningitis (64,7%. Conclusion: On the territory of Krasnoyarsk Krai the MI morbidity is sporadic. The generalized forms of meningococcal infection are characterized by early overt symptoms which make it possible to set a diagnosis. The clinical picture of the generalized forms of the disease almost did not change significantly.

The objective of the present study was to determine the frequency and clinical relevance of HBoV infection in adult patients with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD.Methods: We retrospectively tested 212 COPD patients, 141 (66.5% with AE-COPD and 71 (33.5% with stable disease, of whom nasal lavage and induced sputum had been obtained for the presence of HBoV deoxyribonucleic acid (DNA. The specificity of positive polymerase chain reaction results was confirmed by sequencing.Results: Two hundred two of 212 patients for whom PCR results were available both for nasal lavage and induced sputum samples were eligible for data analysis. HBoV DNA was detected in three patients (1.5%. Of those, only one patient had AE-COPD. Thus, the frequency of HBoV infection demonstrated to be low in both AE-COPD (0.8% and stable COPD (2.9%. HBoV was found in two sputum and one nasal lavage sample in different patients, respectively. Sequencing revealed >99% sequence identity with the reference strain.Conclusion: HBoV detection was infrequent. Since we detected HBoV in both upper and lower respiratory tract specimens and in AE-COPD as well as stable disease, a major role of HBoV infection in adults with AE-COPD is unlikely

    2009-08-01

    Full Text Available Background: Atrial Fibrillation is known to account for one third of all the strokes caused in the US in the population above the age of 70. Patients treated with the surgical Cox MAZE operation have been shown to have a 150 fold decrease in the incidence of stroke over an 18 year period. However, the original Cox MAZE although extremely successful in treating atrial fibrillation and decreasing the incidence of strokes was not performed widely because of complexity and invasiveness of the procedure. A variety of alternative energy based curative ablation strategies are now available for more minimally invasive therapeutic management of atrial fibrillation (AF. In this communication, we report our clinical experience in AF therapy utilizing laser energy ablation technology. Methods: Fifty two consecutive AF patients underwent concomitant or isolated ablation prior to any coexisting cardiac procedures that included CABG (coronary artery bypass surgery, MV (mitral valve or AV (aortic valve repairs. All patients had an epicardially based ablation pattern with basic lesions being en bloc box type pulmonary vein isolation which included the antral surface of the left atrium, directed ganglionectomies of the the right anterior and inferior ganglions, posteriomedial ablation of the IVC ( inferior vena cava, and a right isthmus ablation. Twenty seven patients had ligation of their left atrial appendage, 14 patients had resection of the ligament of Marshall, and three patients had endocardial placed lesions of a mitral annular connecting type lesion. In order to maintain the patients in normal sinus rhythm (NSR, electrical cardioversion and anti-arrhythmic drugs were employed as required. Results: At a median follow-up of 250 days, 44 of the total 52 patients (84.6% exhibited NSR.. No complications or mortality were reported due to the laser procedure. Conclusion: Laser ablation was successfully and safely used for endocardial and epicardial AF ablation

    Viruses rely completely on the hosts' machinery for translation of viral transcripts. However, for most viruses infecting humans, codon usage preferences (CUPrefs) do not match those of the host. Human papillomaviruses (HPVs) are a showcase to tackle this paradox: they present a large genotypic diversity and a broad range of phenotypic presentations, from asymptomatic infections to productive lesions and cancer. By applying phylogenetic inference and dimensionality reduction methods, we demonstrate first that genes in HPVs are poorly adapted to the average human CUPrefs, the only exception being capsid genes in viruses causing productive lesions. Phylogenetic relationships between HPVs explained only a small proportion of CUPrefs variation. Instead, the most important explanatory factor for viral CUPrefs was infection phenotype, as orthologous genes in viruses with similar clinical presentation displayed similar CUPrefs. Moreover, viral genes with similar spatiotemporal expression patterns also showed similar CUPrefs. Our results suggest that CUPrefs in HPVs reflect either variations in the mutation bias or differential selection pressures depending on the clinical presentation and expression timing. We propose that poor viral CUPrefs may be central to a trade-off between strong viral gene expression and the potential for eliciting protective immune response. PMID:26139833

    Elephant endotheliotropic herpesvirus (EEHV) can cause lethal hemorrhagic disease in juvenile Asian elephants. A number of EEHV types and subtypes exist, where most deaths have been caused by EEHV1A and EEHV1B. EEHV4 has been attributed to two deaths, but as both diagnoses were made postmortem, EEHV4 disease has not yet been observed and recorded clinically. In this brief communication, two cases of EEHV4 infection in juvenile elephants at the Houston Zoo are described, where both cases were resolved following intensive treatment and administration of famciclovir. A quantitative real-time polymerase chain reaction detected EEHV4 viremia that correlated with clinical signs. High levels of EEHV4 shedding from trunk wash secretions of the first viremic elephant correlated with subsequent infection of the second elephant with EEHV4. It is hoped that the observations made in these cases--and the successful treatment regimen used--will help other institutions identify and treat EEHV4 infection in the future. PMID:27010293

    Streptococci are common causes of infective endocarditis (IE) and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has provided a practical tool for their species determination. We aimed to investigate if particular groups of non-beta heamolytic streptococci were associated with IE or to specific presentations thereof. The Swedish Registry of Infective Endocarditis was used to identify cases of IE caused by streptococci and a local database to identify cases of streptococcal bacteremia. The bacteria were grouped using MALDI-TOF MS and the clinical characteristics of IE caused by different groups were compared. We identified a group of 201 streptococcal IE isolates: 18 isolates belonged to the anginosus, 19 to the bovis, 140 to the mitis, 17 to the mutans, and seven to the salivarius groups. The mitis and mutans groups were significantly more common and the anginosus group less common among IE cases as compared to all cause bacteremia. Patients infected with the bovis group isolates were older, had more cardiac devices, and had more commonly prosthetic valve IE compared to IE caused by streptococci of the other groups. Twenty-one percent of patients needed surgery, and in-hospital mortality was 8% with no significant differences between the groups. Grouping of non-beta haemolytic streptococci using MALDI-TOF MS can provide a basis for decision-making in streptococcal bacteremia. IE caused by bovis group isolates have clinical characteristics distinguishing them from IE caused by other groups of Streptococcus. PMID:26610338

    Parvovirus B19 infection may be mistakenly reported as measles or rubella if laboratory testing is not performed. As Europe is seeking to eliminate measles, an accurate diagnosis of fever\\/rash illnesses is needed. The main purpose of this study was to describe the epidemiological pattern of parvovirus B19, a common cause of rash, in Ireland between January 1996 and June 2008, using times series analysis of laboratory diagnostic data from the National Virus Reference Laboratory. Most diagnostic tests for presumptive parvovirus B19 infection were done in children under the age of five years and in women of child-bearing age (between 20-39 years-old). As a consequence, most of the acute diagnoses of B19 infection were made in these populations. The most commonly reported reasons for testing were: clinical presentation with rash, acute arthritis, influenza-like symptoms or pregnancy. The time series analysis identified seasonal trends in parvovirus B19 infection, with annual cycles peaking in late winter\\/spring and a six-year cycle for parvovirus B19 outbreaks in Ireland.

    Full Text Available Abstract Infections by Trypanosoma vivax cause great losses to livestock in Africa and Central and South Americas. Outbreaks due this parasite have been occurred with increasing frequency in Brazil. Knowledge of changes caused byT. vivax during the course of this disease can be of great diagnostic value. Thus, clinical signs, parasitemia, hematologic and biochemical changes of cattle experimentally infected by this hemoparasite were evaluated. Two distinct phases were verified during the infection – an acute phase where circulating parasites were seen and then a chronic phase where fluctuations in parasitemia were detected including aparasitemic periods. A constant reduction in erythrocytes, hemoglobin and packed cell volume (PVC were observed. White blood cells (WBC showed pronounced changes such as severe neutropenia and lymphopenia during the acute phase of the illness. Decreases in cholesterol, albumin, aspartate aminotransferase (AST, lactate dehydrogenase (LDH, and increases in glucose, globulin, protein, and alkaline phosphatase (ALP were observed. The “Lins” isolate of T. vivax showed pathogenicity for cattle, and intense parasitemia was detected in the early stages of infection. Circulating parasites were detected for about two months. The most evident laboratory abnormalities were found in WBC parameters, including thrombocytopenia.

    2016-02-01

    Full Text Available Antiretroviral therapy (ART has led to dramatic improvements in the lives of HIV-infected persons. However, residual immune activation, which persists despite ART, is associated with increased risk of non-AIDS morbidities. Accumulating evidence shows that disruption of the gut mucosal epithelium during SIV/HIV infections allows translocation of microbial products into the circulation, triggering immune activation. This disruption is due to immune, structural and microbial alterations. In this review, we highlighted the key findings of gut mucosa studies of SIV-infected macaques and HIV-infected humans that have revealed virus-induced changes of intestinal CD4, CD8 T cells, innate lymphoid cells, myeloid cells, and of the local cytokine/chemokine network in addition to epithelial injuries. We review the interplay between the host immune response and the intestinal microbiota, which also impacts disease progression. Collectively, these studies have instructed clinical research on early ART initiation, modifiers of microbiota composition, and recombinant cytokines for restoring gut barrier integrity.

    Clinical manifestations of human papillomavirus (HPV) infection in the head and neck can range from benign lesions, which are the most frequent, to malignant lesions. The prevalence of head and neck cancer is increasing, despite currently decreasing trends in known risk factors such as smoking and alcohol use. A new patient profile has appeared in recent practice: most frequently a middle-aged male patient who does not smoke or drink alcohol, is sexually active (possibly having multiple partners), and presents with oral or cervicofacial lesions requiring diagnosis and treatment. Another risk factor that should be considered in these patients is HPV infection. The association of oral potentially malignant disorders (OPMD) with HPV is a challenge for the medical practitioner. The gold standard for diagnosis is histopathological examination, which can also yield evidence suggesting HPV infection. Determination of the viral genotype provides additional data for assessing the oncological risk of an HPV infection. Treatment of these patients is aimed at removing the lesions, in association or not with antiviral treatment and recurrence control. PMID:26331491

    2010-02-01

    Timely diagnosis of pleural space infections and rapid initiation of effective pleural drainage for those patients with complicated parapneumonic effusions or empyema represent keystone principles for managing patients with pneumonia. Advances in chest imaging provide opportunities to detect parapneumonic effusions with high sensitivity in patients hospitalized for pneumonia and to guide interventional therapy. Standard radiographs retain their primary role for screening patients with pneumonia for the presence of an effusion to determine the need for thoracentesis. Ultrasonography and CT scanning, however, have greater sensitivity for fluid detection and provide additional information for determining the extent and nature of pleural infection. MRI and PET scan can image pleural disease, but their role in managing parapneumonic effusions is not yet clearly defined. Effective application of chest images for patients at risk for pleural infection, however, requires a comprehensive understanding of the unique features of each modality and relative value. This review presents the diagnostic usefulness and clinical application of chest imaging studies for evaluating and managing pleural space infections in patients hospitalized for pneumonia.

    Full Text Available Studies on the prevalence of infection with hepatitis B virus (HBV among children are scarce in Latin American countries, especially in Mexico. This study was aimed to investigate the prevalence of HBV infection, occult hepatitis B infection (OBI and HBV genotypes among children with clinical hepatitis. In total, 215 children with clinical hepatitis were evaluated for HBV infection. HBV serological markers and HBV DNA were analysed. OBI diagnosis and HBV genotyping was performed. HBV infection was found in 11.2% of children with clinical hepatitis. Among these HBV DNA positive-infected children, OBI was identified in 87.5% (n = 21/24 of the cases and 12.5% (n = 3/24 were positive for both HBV DNA and hepatitis B surface antigen. OBI was more frequent among children who had not been vaccinated against hepatitis B (p < 0.05 than in those who had been vaccinated. HBV genotype H was prevalent in 71% of the children followed by genotype G (8% and genotype A (4%. In conclusion, OBI is common among Mexican children with clinical hepatitis and is associated with HBV genotype H. The results show the importance of the molecular diagnosis of HBV infection in Mexican paediatric patients with clinical hepatitis and emphasise the necessity of reinforcing hepatitis B vaccination in children.

    Metronidazole is an antimicrobial agent mainly used in the treatment of several protozoal and anaerobic infections, additionally, is often used in hepatic encephalopathy and Crohn disease. Apart from peripheral neuropathy, metronidazole can also cause symptoms of central nervous system dysfunction like ataxic gait, dysarthria, seizures, and encephalopathy which may result from both short term and chronic use of this drug and is collectively termed as "metronidazole induced encephalopathy"(MIE). Neuroimaging forms the backbone in clinching the diagnosis of this uncommon entity, especially in cases where there is high index of suspicion of intoxication. Although typical sites of involvement include cerebellum, brain stem and corpus callosum, however, lesions of other sites have also been reported. Once diagnosed, resolution of findings on Magnetic Resonance Imaging (MRI) of the Brain along with clinical improvement remains the mainstay of monitoring. Here we review the key clinical features and MRI findings of MIE as reported in medical literature. We also analyze implication of use of this drug in special situations like hepatic encephalopathy and brain abscess and discuss our experience regarding this entity. PMID:27504340

  6. Treatment of helicobacter pylori infection; a controlled randomized comparative clinical trial

    International Nuclear Information System (INIS)

    Helicobacter pylori induces chronic inflammation of the underlying gastric mucosa and is strongly linked to the development of duodenal and gastric carcinoma. A study was conducted to evaluate the efficacy of Pylorex, a herbal formulation, for treatment of H. pylori infection as compared to triple allopathic therapy (Omeprazole, Amoxicillin, Metronidazole). The therapeutic evaluations of these medicines were conducted on 97 clinically and immunologically diagnosed cases of H. pylori infection. H. pylori was eradicated in 16 (32.6%) out of 49 patients by the use of triple allopathic therapy (Control drugs), and in 9 (18.7%) out of 48 patients by the use of Pylorex (Test drug). Pylorex possesses a therapeutic value for the treatment of H. pylori associated symptoms but the eradication rate is superior in triple allopathic therapy. (author)

    Since 1992 we have investigated HIV antibodies in persons with a venereal disease who worked for a sex business or engaged in sexual behavior with a high risk of HIV infection at five clinics of venereology, urology, and gynecology in Osaka Prefecture. Starting at the end of 2000, we performed a nucleic acid-amplification test (NAT) on antibody-negative samples with the aim of detecting cases in the window period covering the early phase of infection. Three cases that were thought to be in this phase were found in 2006. All were confirmed to be positive in an NAT, although they were negative in initial screening for HIV performed using the IC method. Gene analysis of the env-C2V3 region of HIV-1 showed that the three samples had different origins. PMID:19563237

    Objective To determine the etiology and clinical predictors of peripheral lymphadenopathy in HIV-infected individuals during the antiretroviral (ARV) era in a non-Tuberculosis endemic setting. Methods Multi-centered, retrospective cohort study of peripheral lymph node biopsies in HIV-positive adults. 107 charts were identified and reviewed for clinical features, lymphadenopathy size, ARV use and duration. Biopsy results were categorized, and multivariate logistic regression determined independent predictors of lymphadenopathy etiology. Results Evaluation of 107 peripheral lymph node biopsies revealed 42.9% due to malignancy, 49.5% reactive changes, and 7.5% infections, with only 2.8% of all cases secondary to tuberculosis. Fevers, weight loss, ARV use, and lower viral loads are significantly associated with non-reactive lymphadenopathy. Conclusion Lymphadenopathy is likely to be reactive or malignant in non-Tuberculosis endemic regions. Readily available clinical features can aid clinicians in predicting the underlying etiology, those at risk for malignancy, and who to biopsy. PMID:22805116

    Full Text Available Abstract: Introduction: The drug resistant Acinetobacter strains are important causes of nosocomial infections that are difficult to control and treat. This study aimed to determine the antimicrobial susceptibility patterns of Acinetobacter strains isolated from different clinical specimens obtained from patients belonging to different age groups. METHODS: In total, 716 non-duplicate Acinetobacter isolates were collected from the infected patients admitted to tertiary-care hospitals at Lahore, Pakistan, over a period of 28 months. The Acinetobacter isolates were identified using API 20E, and antimicrobial susceptibility testing was performed and interpreted according to Clinical and Laboratory Standards Institute (CLSI guidelines. RESULTS: The isolation rate of Acinetobacter was high from the respiratory specimens, followed by wound samples. Antibiotic susceptibility analyses of the isolates revealed that the resistance to cefotaxime and ceftazidime was the most common, in 710 (99.2% specimens each, followed by the resistance to gentamicin in 670 (93.6% isolates, and to imipenem in 651 (90.9% isolates. However, almost all isolates were susceptible to tigecycline, colistin, and polymyxin B. CONCLUSIONS: The present study showed the alarming trends of resistance of Acinetobacter strains isolated from clinical specimens to the various classes of antimicrobials. The improvement of microbiological techniques for earlier and more accurate identification of bacteria is necessary for the selection of appropriate treatments.

    Full Text Available Background: Spinal epidural abscess (SEA is uncommon but has a potentially disastrousoutcome. Its early recognition and management may lead to satisfactoryresults. We analyzed the clinical manifestations, sources of infection, andoutcomes of patients with SEA.Methods: Between 1997 and 2003, 17 patients in the Department of Neurosurgery atKeelung Chang Gung Memorial Hospital had SEA. We retrospectivelyreviewed their records to analyze their clinical presentations, image findings,laboratory data, and clinical outcomes.Results: All 17 patients (mean age, 63 years underwent surgery and received antibiotics.Back and/or neck pain (82%, motor deficits (70%, and elevated Creactiveprotein levels or erythrocyte sedimentation rates (64% were themost common symptoms and signs. The most common etiological organismwas oxacillin-resistant Staphylococcus aureus. The SEA was most commonlylocated in the lumbar spine, anterior to the spinal canal. Outcomes werepoor in 29% of the patients, fair in 18%, and good in 53%.Conclusions: Abdominal complications in patients with spinal disease are not uncommon,especially when the thoracic level is involved. The abdominal symptomsmay initially mask neurological deficits due to spinal cord involvement,however, spinal pain and motor deficits present in most cases under morethorough investigation. In a suspected SEA patient with a history of goutyarthritis, tissue biopsy should include additional crystal analysis. Althoughthe increasing availability of MRI makes diagnosis easier and quicker,repeated neurological examination and full evaluation are essential in anypatient with an unknown focus of infection and spinal pain or tenderness.

    Oral human papillomavirus (HPV) infections are less prevalent than genital and anal infections. However, the incidence of oropharyngeal squamous cell carcinomas has increased significantly over the last 2 decades in several countries. At least 90% of these cancers are associated with oncogenic type HPV16. Oral HPV infections are notably more frequent in men than in women, and the incidence of HPV-positive oropharyngeal squamous cell carcinomas has increased, predominantly among mid-adult men. Nevertheless, little is known about the progression of oral HPV infection to cancer, and it remains unclear which medical interventions should be applied to modify the natural history of the disease. This narrative review aimed at non-experts in HPV infection provides an update on oral HPV infection and its clinical management in men. Furthermore, using the cervix as a reference anatomical site, the lessons learned from investigations on cervical HPV infection are also addressed. PMID:24865412

    Full Text Available Abstract Background Super-infection in adult bacterial meningitis (ABM is a condition wherein the cerebrospinal fluid (CSF grows new pathogen(s during the therapeutic course of meningitis. It is an uncommon but clinically important condition rarely examined in literature. Methods Twenty-seven episodes of super-infection states in 21 ABM patients collected in a 9.5-year study period (January 2001 to June 2010 were evaluated. The clinical characteristics, implicated pathogens, results of antimicrobial susceptibility tests, and therapeutic outcomes were analyzed. Results Twenty-one patients (13 men, 8 women aged 25-73 years (median, 45 years had post-neurosurgical state as the preceding event and nosocomial infection. The post-neurosurgical states included spontaneous intracranial hemorrhage (ICH with craniectomy or craniotomy with extra-ventricular drainage (EVD or ventriculo-peritoneal shunt (VPS in 10 patients, traumatic ICH with craniectomy or craniotomy with EVD or VPS in 6 patients, hydrocephalus s/p VPS in 2 patients, and one patient each with cerebral infarct s/p craniectomy with EVD, meningeal metastasis s/p Omaya implant, and head injury. All 21 patients had EVD and/or VP shunt and/or Omaya implant during the whole course of ABM. Recurrent fever was the most common presentation and the implicated bacterial pathogens were protean, many of which were antibiotic resistant. Most patients required adjustment of antibiotics after the pathogens were identified but even with antimicrobial therapy, 33.3% (7/21 died. Morbidity was also high among survivors. Conclusions Super-infection in ABM is usually seen in patients with preceding neurosurgical event, especially insertion of an external drainage device. Repeat CSF culture is mandatory for diagnostic confirmation because most of the implicated bacterial strains are non-susceptible to common antibiotics used. Unusual pathogens like anaerobic bacteria and fungi may also appear. Despite

    Acinetobacter baumannii is one of the most important antibiotic-resistant nosocomial bacteria. We investigated changes in the clinical and molecular epidemiology of A. baumannii over a 10-year period. We compared the data from 2 prospective multicenter cohort studies in Spain, one performed in 2000 (183 patients) and one in 2010 (246 patients), which included consecutive patients infected or colonized by A. baumannii. Molecular typing was performed by repetitive extragenic palindromic polymerase chain reaction (REP-PCR), pulsed-field gel electrophoresis (PFGE), and multilocus sequence typing (MLST). The incidence density of A. baumannii colonization or infection increased significantly from 0.14 in 2000 to 0.52 in 2010 in medical services (p < 0.001). The number of non-nosocomial health care-associated cases increased from 1.2% to 14.2%, respectively (p < 0.001). Previous exposure to carbapenems increased in 2010 (16.9% in 2000 vs 27.3% in 2010, p = 0.03). The drugs most frequently used for definitive treatment of patients with infections were carbapenems in 2000 (45%) and colistin in 2010 (50.3%). There was molecular-typing evidence of an increase in the frequency of A. baumannii acquisition in non-intensive care unit wards in 2010 (7.6% in 2000 vs 19.2% in 2010, p = 0.01). By MSLT, the ST2 clonal group predominated and increased in 2010. This epidemic clonal group was more frequently resistant to imipenem and was associated with an increased risk of sepsis, although not with severe sepsis or mortality. Some significant changes were noted in the epidemiology of A. baumannii, which is increasingly affecting patients admitted to conventional wards and is also the cause of non-nosocomial health care-associated infections. Epidemic clones seem to combine antimicrobial resistance and the ability to spread, while maintaining their clinical virulence. PMID:25181313

    AIM: To study the antibiotic susceptibility patterns of gram-negative healthcare associated bacterial infections at two tertiary hospitals in the Sanandaj city, Kurdistan Province, Iran. METHODS: From January 2012 to December 2012, all positive cultures from potentially sterile body fluids were gathered. They sent to professor Alborzi clinical microbiology center in Shiraz for further analysis and susceptibility testing. The antibiotic susceptibility was determined using the Kirby-Bauer method (disk diffusion technique). The Results were interpreted according to Clinical and Laboratory Standards Institute guidelines against a series of antimicrobials. World Health Organization definitions for Healthcare associated infections were followed. RESULTS: Seven hundred and thirty-two positive cultures were reported from both hospitals. Seventy-nine isolates/patients fulfilled the study criteria for health-care associated gram-negative infections. The most frequent bacterial cultures were from the pediatric wards (52%). Serratia marcescens (S. marcescens) (38%) Escherichia coli (E. coli) (19%), Klebsiella pneumoniae (K. pneumoniae) (19%), Acinetobacter baumannii (6%), Enterobacter species (6%), Serratia odorifera (4%) and Pseudomonas species (5%) were the most frequently isolated organisms. The susceptibility pattern of common isolates i.e., S. marcescens, E. coli and K. pneumoniae for commonly used antibiotics were as follows: Ampicillin 3.3%, 6.7%, 20%; gentamicin 73.3%, 73.3%, 46.7%; ceftazidim 80%, 73.3%, 33.3%; cefepim 80%, 86.7%, 46.7%; piperacillin/tazobactam 90%, 66.7%, 86.7%; ciprofloxacin 100%, 73.3%, 86.7%; imipenem 100%, 100%, 100%, respectively. CONCLUSION: The most effective antibiotics against gram-negative healthcare associated infections are imipenem followed by ciprofloxacin. The resistance rate is high against ampicillin and cephalothin. The high mortality rate (46.1%) associated with S. marcescens is alarming. PMID:26989670

    Extensively drug-resistant (XDR) Gram-negative bacilli (GNB) are defined as bacterial isolates susceptible to two or fewer antimicrobial categories. XDR-GNB mainly occur in Enterobacteriaceae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia. The prevalence of XDR-GNB is on the rise in China and in other countries, and it poses a major public health threat as a result of the lack of adequate therapeutic options. A group of Chinese clinical experts, microbiologists and pharmacologists came together to discuss and draft a consensus on the laboratory diagnosis, clinical management and infection control of XDR-GNB infections. Lists of antimicrobial categories proposed for antimicrobial susceptibility testing were created according to documents from the Clinical Laboratory Standards Institute (CLSI), the European Committee on Antimicrobial Susceptibility Testing (EUCAST) and the United States Food and Drug Administration (FDA). Multiple risk factors of XDR-GNB infections are analyzed, with long-term exposure to extended-spectrum antimicrobials being the most important one. Combination therapeutic regimens are summarized for treatment of XDR-GNB infections caused by different bacteria based on limited clinical studies and/or laboratory data. Most frequently used antimicrobials used for the combination therapies include aminoglycosides, carbapenems, colistin, fosfomycin and tigecycline. Strict infection control measures including hand hygiene, contact isolation, active screening, environmental surface disinfections, decolonization and restrictive antibiotic stewardship are recommended to curb the XDR-GNB spread.

  16. FDG PET/CT in infection and inflammation—current and emerging clinical applications

    International Nuclear Information System (INIS)

    Integrated positron emission tomography/computed tomography (PET/CT) with the glucose analogue, 2-[18F]-fluoro-2-deoxy-D-glucose (FDG), is an evolving hybrid imaging technique in the evaluation of an important and diverse group of pathological conditions, which are characterised by infection and aseptic inflammation. With a rapidly expanding body of evidence, it is being increasingly recognised that, in addition to its established role in oncological imaging, FDG PET/CT also has clinical utility in suspected infection and inflammation. The technique can identify the source of infection or inflammation in a timely fashion ahead of morphological changes on conventional anatomical imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), map the extent and severity of disease, identify sites for tissue sampling, and assess therapy response. FDG PET/CT exhibits distinct advantages over traditional radionuclide imaging techniques in terms of shorter duration of examination, higher spatial resolution, non-invasive nature of acquisition, ability to perform quantitative analyses, and the provision of a synergistic combination of functional and anatomical imaging. With the use of illustrative clinico-radiological cases, this article discusses the current and emerging evidence for the use of FDG PET/CT in a broad spectrum of disorders, such as fever of unknown origin, sarcoidosis, large vessel vasculitis, musculoskeletal infections, joint prosthesis or implant-related complications, human immunodeficiency virus (HIV)-related infections, and miscellaneous indications, such as IgG4-related systemic disease. It will also briefly summarise the role of more novel tracers such as FDG-labelled leukocytes and gallium-68 PET tracers in this arena

    Full Text Available OBJECTIVES: Cytotoxic agents and steroids are used to treat lymphoid malignancies, but these compounds may exacerbate chronic viral hepatitis. For patients with multiple myeloma, the impact of preexisting hepatitis virus infection is unclear. The aim of this study is to explore the characteristics and outcomes of myeloma patients with chronic hepatitis virus infection. METHODS: From 2003 to 2008, 155 myeloma patients were examined to determine their chronic hepatitis virus infection statuses using serologic tests for the hepatitis B (HBV and C viruses (HCV. Clinical parameters and outcome variables were retrieved via a medical chart review. RESULTS: The estimated prevalences of chronic HBV and HCV infections were 11.0% (n = 17 and 9.0% (n = 14, respectively. The characteristics of patients who were hepatitis virus carriers and those who were not were similar. However, carrier patients had a higher prevalence of conventional cytogenetic abnormalities (64.3% vs. 25.0%. The cumulative incidences of grade 3-4 elevation of the level of alanine transaminase, 30.0% vs. 12.0%, and hyperbilirubinemia, 20.0% vs. 1.6%, were higher in carriers as well. In a Kaplan-Meier analysis, carrier patients had worse overall survival (median: 16.0 vs. 42.4 months. The prognostic value of carrier status was not statistically significant in the multivariate analysis, but an age of more than 65 years old, the presence of cytogenetic abnormalities, a beta-2-microglobulin level of more than 3.5 mg/L, and a serum creatinine level of more than 2 mg/ dL were independent factors associated with poor prognosis. CONCLUSION: Myeloma patients with chronic hepatitis virus infections might be a distinct subgroup, and close monitoring of hepatic adverse events should be mandatory.

    2015-01-01

    Abstract Background: The first cases of pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) were described>15 years ago. Since that time, the literature has been divided between studies that successfully demonstrate an etiologic relationship between Group A streptococcal (GAS) infections and childhood-onset obsessive-compulsive disorder (OCD), and those that fail to find an association. One possible explanation for the conflicting reports is that the diagnostic criteria proposed for PANDAS are not specific enough to describe a unique and homogeneous cohort of patients. To evaluate the validity of the PANDAS criteria, we compared clinical characteristics of PANDAS patients identified in two community practices with a sample of children meeting full research criteria for PANDAS. Methods: A systematic review of clinical records was used to identify the presence or absence of selected symptoms in children evaluated for PANDAS by physicians in Hinsdale, Illinois (n=52) and Bethesda, Maryland (n=40). Results were compared against data from participants in National Institute of Mental Health (NIMH) research investigations of PANDAS (n=48). Results: As described in the original PANDAS cohort, males outnumbered females (95:45) by ∼ 2:1, and symptoms began in early childhood (7.3±2.7 years). Clinical presentations were remarkably similar across sites, with all children reporting acute onset of OCD symptoms and multiple comorbidities, including separation anxiety (86–92%), school issues (75–81%), sleep disruptions (71%), tics (60–65%), urinary symptoms (42–81%), and others. Twenty of the community cases (22%) failed to meet PANDAS criteria because of an absence of documentation of GAS infections. Conclusions: The diagnostic criteria for PANDAS can be used by clinicians to accurately identify patients with common clinical features and shared etiology of symptoms. Although difficulties in documenting an association

    The clinical laboratory, virologic, and pathologic changes occurring in hamsters after infection with Pirital virus (Arenaviridae) are described. Pirital virus infection in the hamsters was characterized by high titered viremia, leukocytosis, coagulopathy, pulmonary hemorrhage and edema, hepatocellular and splenic necrosis, and marked elevation of serum transaminase levels. All of the animals died within 9 days. The clinical and histopathological findings in the Pirital virus-infected hamsters were very similar to those reported in severe human cases of Lassa fever, suggesting that this new animal model could serve as a low-cost and relatively safe alternative for studying the pathogenesis and therapy of Lassa fever.

    Full Text Available Background: Cryptococcal meningitis is a common opportunistic infection in Human Immunodeficiency Virus (HIV-infected individuals. There is little information specifically addressing cryptococcal meningitis in HIV-infected patients from North India. Aims: To determine clinical presentation, hospital course, response to treatment, complications developed, in-hospital mortality, any recurrence of cryptococcal meningitis and reasons of recurrence during follow-up. Settings and Design: A retrospective observational study undertaken in a large tertiary care center. Materials and Methods: Patient′s demographic data, presenting clinical symptomatology, physical findings, laboratory parameters, cerebrospinal fluid (CSF examination findings, side-effects of treatment, development of any complications and hospital outcome were analyzed. During follow-up any recurrence of cryptococcal meningitis, possible reasons of recurrence, type of treatment received, complications developed and outcome was recorded as well. Results: Forty patients diagnosed to have cryptococcal meningitis were analyzed. Twenty-two (55% patients had acute/ subacute presentation. Thirty-six (90% patients presented with headache and 18 (45% had altered sensorium. Twenty (50% patients had no cells in the CSF. Hypoglycorrhchia was seen in 30 (75% patients. Cryptococcal meningitis was the first acquired immune deficiency syndrome (AIDS-defining illness in 30 (75% patients. Thirty-five patients developed some adverse effects to amphotericin-B. Thirty-three patients improved with treatment while three patients died. Four patients had recurrence of cryptococcal meningitis within six months of first episode. Non-compliance of fluconazole therapy was the reason for recurrence in all of these patients. Conclusions: Cryptococcal meningitis is a common initial AIDS-defining illness. Acute and/or subacute presentation of cryptococcal meningitis is not uncommon in HIV-infected individuals. An early

    Purpose: Our goal is to evaluate the performance of the Ciprofloxacin-Tc99m Scintigraphy in the detection of infection sites in bones, joints and soft tissues. Material and Methods: We analyze 60 exams of Ciprofloxacin-Tc99m from 8-12-2001 to 16-04-2004 in our institution. 10 patients were discarded owing to lack of clinical data or bacteriologic confirmation. The 50 patients evaluated were divided in: 32 hips, 7 knees, 2 femur, 1 leg, 3 feet, 3 spines, and 2 soft tissues. We used a planar gamma camera (technicare omega 500) and a SPECT gamma camera (elscint spx-2) All the percentages concerning sensibility and specificity were obtained including only those patients with absolute confirmation. Results: From the 50 patients, 30 were diagnosed as positives for infection; 27 corresponding to true positives and 3 to false positives (2 knees and 1 foot), sensibility 84.4%; 20 were diagnosed negatives for infection, 15 corresponding to true negatives and 5 to false negatives (4 hips and 1 spine); specificity 83%. All the exams were evaluated separately by two specialists in Nuclear Medicine; and then discussed until reaching a consensus. Conclusions: Our study shows a good sensibility for diagnosing a great variety of bacterial infectious processes. We achieved a fast localization of the infection site in order to determine the surgical option or the drainage of the abscess; and also in the clinical aspect of the treatment, monitoring the response and the lapse of the antibiotic therapy.

    Photoacoustic imaging has evolved into a clinically translatable platform with the potential to complement existing imaging techniques for the management of cancer, including detection, characterization, prognosis, and treatment monitoring. In photoacoustic imaging, tissue is optically excited to produce ultrasonographic images that represent a spatial map of optical absorption of endogenous constituents such as hemoglobin, fat, melanin, and water or exogenous contrast agents such as dyes and nanoparticles. It can therefore provide functional and molecular information that allows noninvasive soft-tissue characterization. Photoacoustic imaging has matured over the years and is currently being translated into the clinic with various clinical studies underway. In this review, the current state of photoacoustic imaging is presented, including techniques and instrumentation, followed by a discussion of potential clinical applications of this technique for the detection and management of cancer.

    There is a relationship between exercise and changes in immunity. So athletes are prone to different medical problems such as injuries and infections. Infection is an important medical problem which could be a reason for athletes' absence from training. The relationship between physical activity and immune system, characteristics of different types of infections in athletes with emphasis on special clinical presentations or complications, time to return to physical activity and training and strategies to prevent development and transmission of infections in athletes or physically active people are the main topics of this review.

    Abnormalities at cerebral proton spectroscopy occur in patients with the acquired immunodeficiency syndrome (AIDS). N-acetyl aspartate (NAA) is believed to be a neuronal marker, and neuronal loss is thought to underlie the human immunodeficiency virus (HIV)-associated cognitive/motor complex. The proton spectra in 103 HIV-seropositive patients and 23 control subjects were compared and correlated with clinical, immunologic, and radiologic measures of HIV infection. Significant (P suppression and neurologic signs. Significant increases in the Cho/Cr ratios were seen in patients with low CD4 lymphocyte counts and abnormal magnetic resonance (MR) images. Reduced NAA ratios correlated with diffuse but not focal MR imaging abnormalities. Combined MR imaging and spectroscopy provides closer relationships to clinical and immunologic measures of disease than either modality alone. Spectroscopy is an adjunct to MR imaging and augments the value of an MR imaging study. PMID:8099750

    Full Text Available At present, the problem of infective endocarditis (IE remains relevant for clinicians of different specialties, including rheumatologists. The distinctive feature of present-day IE is its polyetiological pattern due to a broad spectrum of pathogens. The lecture highlights in detail clinical picture of the disease, laboratory and instrumental findings. It presents current international diagnostic criteria for IE. The obvious clinical polymorphism, subtle symptoms, and monosyndromic onset as masks, all increases the significance of differential diagnosis of IE, in early disease stages in particular. Main approaches to differentiating IE from diseases posing the greatest differentially diagnostic challenges are set forth.

    The objective of this study was to ascertain the seroprevalence and clinical manifestations of HIV-1 infection in Kananga, Zaire, in 1988. In the city of Kananga (population 300,000), eight out of 258 (3.1%) consecutive, asymptomatic, prenatal patients were seropositive. Of 452 consecutive blood donors at our institution, eight (1.8%) were seropositive. Sixty per cent of 299 consecutive, seropositive, clinically ill adults presented with chronic diarrhea, fever or weight loss (Centers for Disease Control group IVA). The male-to-female ratio of symptomatic, seropositive patients was 1:1.5. Women who indicated on a socioeconomic questionnaire that they engaged in 'commerce' (meaning possibly that they were petty traders, wholesale brokers, or prostitutes) were more often HIV-seropositive than women who did not engage in 'commerce' (P less than 0.001).

    1990-01-01

    Cefuroxime axetil (C.A.E.) is a broad spectrum cephalosporin, suitable for oral route. Its antibacterial activity includes all the pathogens usually responsible for E.N.T. infection, with low M.I.C.'s: H. influenzae, S. pneumoniae, S. aureus, S. pyogene. The stability of the drug against betalactamases, especially those produced by H. influenzae, associated with good bio availability (50%) and tissue penetration (30%) account for the potent in vivo bactericidal activity and clinical efficacy of cefuroxime axetil. More than 1,000 patients had been enrolled in controlled clinical trials: the success rates yielded by C.A.E. were 98%, 96% and 91%, respectively for pharingitis/tonsilitis, otitis media and acute sinusitis. C.A.E. is at least as effective as amoxycillin/clavulanic acid and safety appears to be better. PMID:2087617

    Full Text Available Cat Scratch Disease (CSD is an infective disease of animals and humans caused with Bartonella henselae. Prevalence of infection varies between 0 and 68% depending on different population of cats and geographical region. Naturally infected cats are often clinically healthy and are inapparent germ carriers. In this investigation 40 cats from the area of Novi Sad were analyzed. After the epidemiological questionnaire was made, all cats were clinically investigated. To determine the presence of specific antibodies of class G on Bartonella henselae the method of indirect immunofluorescence was used. For the first time in Serbia, in the area of Novi Sad municipality the infection caused by Bartonella henselae in the population of cats was detected. Prevalence of specific antibodies of class IgG on Bartonella henselae antigen in the population of cats was 57%. The most common clinical manifestations in seropositive cats were gingivitis and lymphoadenopathy.

    1992-05-01

    Over the past 6 years, the city of Baltimore has successfully implemented a school placement policy for human immunodeficiency virus (HIV)-infected children and children with acquired immunodeficiency syndrome (AIDS). Both policy and specific procedures are based on nationally promulgated guidelines. School placement policy is part of an overall AIDS policy that includes education of students and staff and adoption of universal precautions to prevent transmission of communicable diseases in school. Implementation has been marked by excellent collaboration between the departments of health and education. Important policy components include expedited clinical investigation of each case, an interagency review panel, strict protection of confidentiality, a restricted setting for certain children, a school site visit for each placement, and continued monitoring of the school placement by school nurses. Many HIV-infected students need special educational services and/or school health services. The Baltimore City school placement process has avoided the exaggerated publicity endured by some communities, where media reporting has aggravated community fears and invaded the lives of families with HIV-infected children. Baltimore City has succeeded in ensuring access to education, protecting families' confidentiality, and providing special care for HIV-infected students. Local communities should emphasize national guidelines in designing school placement policies for HIV-infected children. School placement policies work best in the context of a comprehensive policy incorporating AIDS education and care. PMID:1579392

    Full Text Available Background & Aims: Detection of hepatitis C virus RNA in peripheral blood mononuclear cells (PBMC and/or hepatocytes in the absence of HCV RNA in serum, designated as ‘occult HCV infection’, has been a matter of controversy in the recent years. Occult hepatitis C virus (HCV infection has not been investigated in haemodialysis patients. We investigated for the first time the prevalence of occult HCV infection in large cohorts of chronic hemodialysis (CHD patients in a single heamodialysis center at Al-Taif, KSA. Methods: We enrolled 84 CHD patients, whose sera are negative for HCV markers. HCV RNA was tested in PBMC using a sensitive commercial real time assay. In this study, real-time PCR was used to test for the presence of genomic HCV-RNA in peripheral blood mononuclear cells of all of these patients. For comparison, 20 patients on HD with evidence of chronic hepatitis C virus infection were included as a control group. Results: In CHD patients, occult HCV infection, determined by the presence of genomic HCV-RNA in peripheral blood mononuclear cells (PBMNCs, was found in 13.4 % of the patients; 83 % of these patients had ongoing HCV replication, indicated by the presence of HCV-RNA. Patients with occult HCV infection had spent a significantly longer time on heamodialysis and had significantly higher mean alanine aminotransferase levels during the 3 months before study entry. Compared to CHCV patients, those with occult HCV have less elevated bilirubin, AST and ALT. Conclusions: The prevalence of occult HCV infection was moderate in our CHD patients, and it did not appear to be clinically relevant. Further studies in other geographic populations with high HCV endemicity are required to clarify the significance of occult HCV infection in these patient groups.

    Umeh, E. U.; Ishaleku, D.; Iheukwumere, C. C.

    Human immunodeficiency virus (HIV) and Mycobacterium tuberculosis (TB) coinfection rate was investigated among patients referred to a chest clinic in Nasarawa State, Nigeria. Out of the 344 patients who presented with respiratory problems at the clinic, 44.8% had M. tuberculosis infection, 24.7% HIV infection and 12.8% HIV/tubercle bacilli co-infection. Coinfection rate in HIV infected persons (HIV+) was 51.8 and 28.6% in those with M. tuberculosis infection. The relative risk of HIV positive persons being coinfected was 1.075, while it was 0.401 for TB infected persons. The estimated Odds Ratio (OR) shows that the risk of co-infection was 2.68 times higher among HIV+ persons than among those with tuberculosis. The attributable risk was 45% and shows the extent to which co-infection could be attributed to HIV infection. A key socio-economic variable, eating in groups, was significantly correlated with coinfection (r = 0.107; p< 0.05). The results of this study may provide a useful policy guide in the formulation of HIV and tuberculosis control measures in Nigeria.

    Stigma has become a gendered phenomenon that affects increasing numbers of HIV-infected women worldwide. This study examined the role of age as a possible moderator of the relationship between stigma and antiretroviral therapy adherence, CD4% and viral load among 120 HIV-infected women. A secondary analysis was conducted using data from the Keeping Healthy and Active with Risk Reduction and Medication Adherence (KHARMA) Project, an National Institutes of Health (NIH) funded randomized controlled trial to improve Antiretroviral treatment (ART) adherence and reduce risky behaviors in HIV-infected women at five clinical sites in a South-eastern city from 2005 to 2008. Stigma was measured using the Perceived Personal Stigma of Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) scale. Among participants 50 years old, age was not significantly associated with viral load, stigma or CD4%, and there was no significant association between stigma and CD4% (r=.07, p=.70). These findings indicate the need for further study regarding this potential moderating effect and possible interventions to address the susceptibility of younger women to the harmful effects of stigma.

    Full Text Available BACKGROUND: Buruli ulcer (BU is a skin disease caused by Mycobacterium ulcerans, with endemicity predominantly in sub-Saharan Africa and south-eastern Australia. The mode of transmission and the environmental reservoir(s of the bacterium and remain elusive. Real-time PCR investigations have detected M. ulcerans DNA in a variety of Australian environmental samples, including the faeces of native possums with and without clinical evidence of infection. This report seeks to expand on previously published findings by the authors' investigative group with regards to clinical and subclinical disease in selected wild possum species in BU-endemic areas of Victoria, Australia. METHODOLOGY/PRINCIPAL FINDINGS: Twenty-seven clinical cases of M. ulcerans infection in free-ranging possums from southeastern Australia were identified retrospectively and prospectively between 1998-2011. Common ringtail possums (Pseudocheirus peregrinus, a common brushtail possum (Trichosurus vulpecula and a mountain brushtail possum (Trichosurus cunninghami were included in the clinically affected cohort. Most clinically apparent cases were adults with solitary or multiple ulcerative cutaneous lesions, generally confined to the face, limbs and/or tail. The disease was minor and self-limiting in the case of both Trichosurus spp. possums. In contrast, many of the common ringtail possums had cutaneous disease involving disparate anatomical sites, and in four cases there was evidence of systemic disease at post mortem examination. Where tested using real-time PCR targeted at IS2404, animals typically had significant levels of M. ulcerans DNA throughout the gut and/or faeces. A further 12 possums without cutaneous lesions were found to have PCR-positive gut contents and/or faeces (subclinical cases, and in one of these the organism was cultured from liver tissue. Comparisons were made between clinically and subclinically affected possums, and 61 PCR-negative, non-affected individuals

    The objective of this study was to determine whether the effect of cognitive reserve (CR) on neuropsychological functioning differs according to the clinical stage of HIV infection. A sample of 34 HIV-positive individuals aged 23-49, with a minimum of 9 years of formal education, was assessed. Participants were grouped according to the Centers for Disease Control and Prevention's (CDC) clinical stages (A = 10, B = 16, C = 8). CR was calculated for each clinical stage group in accordance with estimates of premorbid IQ, years of education, and occupational attainment. The sum of these three variables was then transformed into z-scores. Individuals above the median were classified as having "High" CR (HCR), those below the median were classified as "Low" CR (LCR). Participants completed an evaluation of cognitive and executive functions based on selected, modified tasks from the HIV University of Miami Annotated Neuropsychological test in Spanish (HUMANS). Assessment included the following domains: attention, memory (visual, verbal, and working memory), executive functions (cognitive flexibility, switching), language (naming), and visual constructive skills (block design). HCR outperformed LCR in all cognitive domains. Comparison of HCR and LCR in each clinical stage revealed that the effect of CR was stronger in stage B than in stages A and C, suggesting that this effect does indeed vary among stages.

    2006-02-01

    Dalbavancin, a new-generation semisynthetic lipoglycopeptide in phase 3 clinical development, has been documented to be more active than vancomycin or teicoplanin against Gram-positive bacteria, including multidrug-resistant strains, by in vitro testing and in animal models. The human pharmacokinetics of dalbavancin predicts efficacy at weekly dosing intervals. In a phase 2 open-label clinical trial, dalbavancin exhibited superiority when compared with vancomycin against catheter-related bloodstream infection (CR-BSI). The majority of pathogens identified in this study as in clinical practice were coagulase-negative staphylococci (CoNS), necessitating rigorous characterization of duplicate isolates to rule out contaminants and to validate cases for study evaluations. At follow-up for the intent-to-treat population, overall pathogen eradication was 92.3% for dalbavancin and 75.9% for vancomycin. We describe the details of organisms isolated, their epidemiologic/genetic characterization, susceptibility patterns against glycopeptides, and the eradication rates by organism group. In conclusion, dalbavancin was active against all isolated pathogens associated with CR-BSI (CoNS, Staphylococcus aureus and Enterococcus faecalis; all MIC results, < or = 0.25 microg/mL) and achieved significant (P < 0.05) clinical success when compared with vancomycin.

    The medical records of 91 dogs with heartworm (Dirofilaria immitis) infection were reviewed, and diagnoses were established by using parasitological and immunological methods. Twenty-one animals were asymptomatic (stage I), 57 had mild to moderate clinical signs (stage II), and 13 had the severe form of the disease including right congestive heart failure and the caval syndrome (stage III). Thoracic radiography revealed right ventricular enlargement in 38 of the dogs, pulmonary vascular enlargement in 43, and parenchymal lesions in 27. Only the cardiac and vascular changes were correlated positively with the clinical stages. D. immitis microfilaraemia was detected in 75 of 85 dogs. Occult infection occurred only in eight stage II and two stage III dogs. Thirty-two of the dogs were treated with thiacetarsamide and 39 were treated with melarsomine, and no differences were found in terms of drug efficacy or complication rate; nine stage II dogs suffered pulmonary thromboembolism and one suffered acute liver disease and there were six fatalities. The 50 treated dogs in stages II and III which were followed up for six months all recovered completely. The performance of 38 of 61 working dogs was completely restored, and the performance of another four was partially restored. PMID:10819132

    10 patients with serious infections caused by Staphylococcus epidermidis (8 cases of endocarditis in non-prosthetic valves, 1 was complicated by osteomyelitis, 1 case of osteomyelitis, and 1 case of septicemia) are described. Clinical and microbiologic features were evaluated including antibiotic sensitivity and synergy studies, phage typing and biotyping. Endocarditis tended to affect the elderly population and the clinical manifestations were quite similar to those caused by Streptococcus viridans. Both patients with osteomyelitis had involvement of the cervical spine with excellent response to antibiotic therapy. The only patient with septicemia acquired via hyperalimentation had delayed clearance of the bacteremia but ultimately responded to intravenous antibiotics. Rifampicin was the most effective of all antibiotics tested. All isolates were sensitive to penicillinase-resistant penicillins and cephalosporins and over half were sensitive to penicillin. Full synergistic activity was demonstrated with cephalothin and nafcillin in combination with rifampicin, and rifampicin-vancomycin was partially synergistic against the majority of the strains. Five of 8 available isolates were non-phage typeable and no definite pattern was established for various types of infections. Four of the 8 isolates were classified as biotype SIIa, 2 biotype SIIc and 2 biotype SVh. PMID:6361977

    Alessandro S Farias

    Full Text Available BACKGROUND: Experimental autoimmune encephalomyelitis (EAE is used as an animal model for human multiple sclerosis (MS, which is an inflammatory demyelinating autoimmune disease of the central nervous system characterized by activation of Th1 and/or Th17 cells. Human autoimmune diseases can be either exacerbated or suppressed by infectious agents. Recent studies have shown that regulatory T cells play a crucial role in the escape mechanism of Plasmodium spp. both in humans and in experimental models. These cells suppress the Th1 response against the parasite and prevent its elimination. Regulatory T cells have been largely associated with protection or amelioration in several autoimmune diseases, mainly by their capacity to suppress proinflammatory response. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we verified that CD4(+CD25(+ regulatory T cells (T regs generated during malaria infection (6 days after EAE induction interfere with the evolution of EAE. We observed a positive correlation between the reduction of EAE clinical symptoms and an increase of parasitemia levels. Suppression of the disease was also accompanied by a decrease in the expression of IL-17 and IFN-γ and increases in the expression of IL-10 and TGF-β1 relative to EAE control mice. The adoptive transfer of CD4(+CD25(+ cells from P. chabaudi-infected mice reduced the clinical evolution of EAE, confirming the role of these T regs. CONCLUSIONS/SIGNIFICANCE: These data corroborate previous findings showing that infections interfere with the prevalence and evolution of autoimmune diseases by inducing regulatory T cells, which regulate EAE in an apparently non-specific manner.

    Infection or reactivation of human herpesvirus (HHV)-6 represents a potentially serious complication (often involving the central nervous system) in patients receiving either solid organ or hematopoietic stem cell transplantation. The objective of this study was to assess the risk of HHV-6 infection/reactivation in mesenchymal stromal cells (MSCs). MSCs are multipotent cells displaying immunomodulatory properties that have been already successfully used in the clinical setting to enhance hematopoietic stem cell engraftment and to treat steroid-refractory acute graft-versus-host disease. We analyzed 20 samples of ex vivo expanded MSCs, at different passages of culture, isolated both from bone marrow and from umbilical cord blood. Through Western blotting and immunocytochemistry techniques, we investigated the presence of the HHV-6 receptor (CD46) on cell surface, whereas the presence of HHV-6 DNA was evaluated by nested polymerase chain reaction assay. All of the MSC samples tested were positive for the virus receptor (CD46), suggesting their potential susceptibility to HHV-6. However, none of the MSC samples derived from cultures, performed in the perspective of clinical use, was found to harbor HHV-6. This preliminary observation on a consistent number of MSC samples, some of them tested at late in vitro passages, indicates a good safety profile of the product in terms of HHV-6 contamination. Nevertheless, it remains important to set up in vitro experimental models to study MSCs' susceptibility to HHV-6 (and HHV-7) infection, to verify their capacity to integrate the virus into cellular DNA, and to investigate which experimental conditions are able to induce virus reactivation.

    Full Text Available BACKGROUND: HIV-1 subtype D infections, which are associated with a faster rate of progression and lymphocyte CD4 decline, cognitive deficit and higher mortality, have rarely been found in native Europeans. In Northwestern Poland, however, infections with this subtype had been identified. This study aimed to analyze the sequence and clinical data for patients with subtype D using molecular phylogeography and identify transmission clusters and ancestry, as well as drug resistance, baseline HIV tropism and antiretroviral treatment efficacy. METHODS: Phylogenetic analyses of local HIV-1 subtype D sequences were performed, with time to the most recent common ancestor inferred using bayesian modeling. Sequence and drug resistance data were linked with the clinical and epidemiological information. RESULTS: Subtype D was found in 24 non-immigrant Caucasian, heterosexually infected patients (75% of females, median age at diagnosis of 49.5 years; IQR: 29-56 years. Partial pol sequences clustered monophyletically with the clades of Ugandan origin and no evidence of transmission from other European countries was found. Time to the most common recent ancestor was 1989.24 (95% HPD: 1968.83-1994.46. Baseline drug resistance to nucleoside reverse transcriptase inhibitors was observed in 54.5% of cases (mutations: M41L, K103N, T215S/D with evidence of clustering, no baseline integrase or protease resistance and infrequent non-R5 tropism (13.6%. Virologic failure was observed in 60% of cases and was associated with poor adherence (p<0.001 and subsequent development of drug resistance (p = 0.008, OR: 20 (95%CI: 1.7-290. CONCLUSIONS: Local subtype D represented an independently transmitted network with probably single index case, high frequency of primary drug resistance and evidence of transmission clusters.

    Full Text Available The bacterium Rickettsia rickettsii is the etiological agent of an acute, severe disease called Rocky Mountain spotted fever in the United States or Brazilian spotted fever (BSF in Brazil. In addition to these two countries, the disease has also been reported to affect humans in Mexico, Costa Rica, Panama, Colombia and Argentina. Like humans, dogs are also susceptible to R. rickettsii infection. However, despite the wide distribution of R. rickettsii in the Western Hemisphere, reports of R. rickettsii-induced illness in dogs has been restricted to the United States. The present study evaluated the pathogenicity for dogs of a South American strain of R. rickettsii. Three groups of dogs were evaluated: group 1 (G1 was inoculated ip with R. rickettsii; group 2 (G2 was infested by R. rickettsii-infected ticks; and the control group (G3 was infested by uninfected ticks. During the study, no clinical abnormalities, Rickettsia DNA or R. rickettsii-reactive antibodies were detected in G3. In contrast, all G1 and G2 dogs developed signs of rickettsial infection, i.e., fever, lethargy, anorexia, ocular lesions, thrombocytopenia, anemia and detectable levels of Rickettsia DNA and R. rickettsii-reactive antibodies in their blood. Rickettsemia started 3-8 days after inoculation or tick infestation and lasted for 3-13 days. Our results indicate that a Brazilian strain of R. rickettsii is pathogenic for dogs, suggesting that canine clinical illness due to R. rickettsii has been unreported in Brazil and possibly in the other South American countries where BSF has been reported among humans.

    The inflammatory response induced by burn injury contributes to increased incidence of infections, sepsis, organ failure, and mortality. Thus, monitoring post-burn inflammation is of paramount importance but so far there are no reliable biomarkers available to monitor and/or predict infectious complications after burn. As IL-8 is a major mediator for inflammatory responses, the aim of our study was to determine whether IL-8 expression can be used to predict post-burn sepsis, infections, and mortality other outcomes post-burn. Plasma cytokines, acute phase proteins, constitutive proteins, and hormones were analyzed during the first 60 days post injury from 468 pediatric burn patients. Demographics and clinical outcome variables (length of stay, infection, sepsis, multiorgan failure (MOF), and mortality were recorded. A cut-off level for IL-8 was determined using receiver operating characteristic (ROC) analysis. Statistical significance is set at (p<0.05). ROC analysis identified a cut-off level of 234 pg/ml for IL-8 for survival. Patients were grouped according to their average IL-8 levels relative to this cut off and stratified into high (H) (n=133) and low (L) (n=335) groups. In the L group, regression analysis revealed a significant predictive value of IL-8 to percent of total body surface area (TBSA) burned and incidence of MOF (p<0.001). In the H group IL-8 levels were able to predict sepsis (p<0.002). In the H group, elevated IL-8 was associated with increased inflammatory and acute phase responses compared to the L group (p<0.05). High levels of IL-8 correlated with increased MOF, sepsis, and mortality. These data suggest that serum levels of IL-8 may be a valid biomarker for monitoring sepsis, infections, and mortality in burn patients. PMID:25514427

    Objective To investigate the clinical characteristics and imaging manifestations of AIDS complicated with disseminated Penicillium marneffei (PM) infection. Methods A total of 12 patients with AIDS complicated with disseminated PM infection were collected and the symptoms, signs, laboratory examination results and image manifestations of these patients were analyzed retrospectively. Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100%) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66%) had skin rashes; 8 cases (66%) had hepatomegaly; 9 cases (75%) had splenomegaly while 8 cases (66%) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes <50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of "cakes".

    There is an increased risk of acute rejection (AR) in human immunodeficiency virus-positive (HIV+) kidney transplant (KT) recipients. Induction immunosuppression is standard of care for those at high risk of AR; however, use in HIV+ patients is controversial, given fears of increased infection rates. We sought to compare clinical outcomes between HIV+ KT recipients who were treated with (i) anti-thymocyte globulin (ATG), (ii) IL-2 receptor blocker, and (iii) no induction. We studied 830 HIV+ KT recipients between 2000 and 2014, as captured in the Scientific Registry of Transplant Recipients, and compared rates of delayed graft function (DGF), AR, graft loss and death. Infections and hospitalizations were ascertained by International Classification of Diseases, Ninth Revision codes in a subset of 308 patients with Medicare. Compared with no induction, neither induction agent was associated with an increased risk of infection (weighted hazard ratio [wHR] 0.80, 95% confidence interval [CI] 0.55-1.18). HIV+ recipients who received induction spent fewer days in the hospital (weighted relative risk [wRR] 0.70, 95% CI 0.52-0.95), had lower rates of DGF (wRR 0.66, 95% CI 0.51-0.84), less graft loss (wHR 0.47, 95% CI 0.24-0.89) and a trend toward lower mortality (wHR 0.60, 95% CI 0.24-1.28). Those who received induction with ATG had lower rates of AR (wRR 0.59, 95% CI 0.35-0.99). Induction in HIV+ KT recipients was not associated with increased infections; in fact, those receiving ATG, the most potent agent, had the lowest rates. In light of the high risk of AR in this population, induction therapy should be strongly considered. PMID:27111897

    Full Text Available OBJECTIVE: To describe the clinical manifestations and outcome of acute liver failure (ALF associated with dengue viral infection, a rare but severe complication. METHODS: One hundred and fifty five consecutive patients with ALF admitted to the national liver centre from 2001 to 2009 were reviewed retrospectively. Eight cases due to dengue infection were identified and their clinical characteristics are described. RESULTS: All patients had severe dengue with one dengue shock syndrome. The median (minimum, maximum age was 33.5 (17, 47 years with 50% female. The median (minimum, maximum duration from the onset of fever to development of ALF was 7.5 (5, 13 days and the maximum hepatic encephalopathy (HE grade were III in five patients and II in three patients. Three patients had systemic inflammatory responses (SIRS on admission and were in grade III HE. The presence of SIRS on admission was associated with higher grade of HE and its development during the course of hospitalization was associated with worsening HE grade. The hepatitis was characterized by marked elevations in: alanine transaminase [median admission 1140.5 u/L (639, 4161; median peak 2487 u/L (998, 5181], serum bilirubin [median admission 29 µmol/L (23, 291; median peak 127 µmol/L (72, 592], and prothrombin time [median admission 16.8 s (15.3, 26.2; median peak 22 s (15.3, 40.7]. The survival rate with standard medical therapy alone was 100%. CONCLUSIONS: Dengue associated ALF manifest about one week after the onset of fever with severe hepatitis and encephalopathy. In our experience, the outcome with standard medical therapy alone is excellent.

    Michael L Levin

    Full Text Available Rocky Mountain spotted fever (RMSF is a tick-borne disease caused by R. rickettsii in North and South America. Domestic dogs are susceptible to infection and canine RMSF can be fatal without appropriate treatment. Although clinical signs of R. rickettsii infection in dogs have been described, published reports usually include descriptions of either advanced clinical cases or experimental infections caused by needle-inoculation of cultured pathogen rather than by tick bite. The natural progression of a tick-borne R. rickettsii infection has not been studied in sufficient detail. Here, we provide a detailed description of clinical, hematological, molecular, and serological dynamics of RMSF in domestic dogs from the day of experimental exposure to infected ticks through recovery. Presented data indicate that neither the height/duration of fever nor detection of rickettsial DNA in dogs' blood by PCR are good indicators for clinical prognosis. Only the apex and subsequent subsidence of neutrophilia seem to mark the beginning of recovery and allow predicting a favorable outcome in Rickettsia-infected dogs, even despite the continuing persistence of mucosal petechiae and skin rash. On the other hand the appropriate (doxycycline antibiotic therapy of sufficient duration is crucial in prevention of RMSF relapses in dogs.

    Objectives From previous data in animal models of cerebral ischemia, lipocalin-2 (LCN2), a protein related to neutrophil function and cellular iron homeostasis, is supposed to have a value as a biomarker in ischemic stroke patients. Therefore, we examined LCN2 expression in the ischemic brain in an animal model and measured plasma levels of LCN2 in ischemic stroke patients. Methods In the mouse model of transient middle cerebral artery occlusion (tMCAO), LCN2 expression in the brain was analyzed by immunohistochemistry and correlated to cellular nonheme iron deposition up to 42 days after tMCAO. In human stroke patients, plasma levels of LCN2 were determined one week after ischemic stroke. In addition to established predictive parameters such as age, National Institutes of Health Stroke Scale and thrombolytic therapy, LCN2 was included into linear logistic regression modeling to predict clinical outcome at 90 days after stroke. Results Immunohistochemistry revealed expression of LCN2 in the mouse brain already at one day following tMCAO, and the amount of LCN2 subsequently increased with a maximum at 2 weeks after tMCAO. Accumulation of cellular nonheme iron was detectable one week post tMCAO and continued to increase. In ischemic stroke patients, higher plasma levels of LCN2 were associated with a worse clinical outcome at 90 days and with the occurrence of post-stroke infections. Conclusions LCN2 is expressed in the ischemic brain after temporary experimental ischemia and paralleled by the accumulation of cellular nonheme iron. Plasma levels of LCN2 measured in patients one week after ischemic stroke contribute to the prediction of clinical outcome at 90 days and reflect the systemic response to post-stroke infections.

    The "Minimum Information for the Publication of qPCR Experiments" (MIQE [3]) guidelines are very much targeted at basic research experiments and have to our knowledge not been applied to qPCR assays carried out in the context of clinical trials. This report details the use of the MIQE qPCR app for iPhone (App Store, Apple) to assess the MIQE compliance of one clinical and five pre-clinical trials. This resulted in the need to include 14 modifications that make the guidelines more relevant for the assessment of this special type of application. We also discuss the need for flexibility, since while some parameters increase experimental quality, they also require more reagents and more time, which is not always feasible in a clinical setting.

    This study studied the use of ERCP and nasobiliary tube in the diagnosis of fungal infection of biliary tract and the efficacy of combined use of local administration via nasobiliary tube and intravenous antifungal treatment for severe biliary tract fungal infection. 5 patients in our series,with age ranging from 47 to 68 y (mean 55.8), were diagnosed as having mixed bacterial and fungal infection of biliary tract as confirmed by smear or/and culture of bile obtained by ERCP and nasobiliary drainage. Besides routine anti-bacteria therapy, all patients received local application of fluconazole through nasobiliary tube and intravenous administration of fluconazole or itraconazole in terms of the results of in vitro sensitivity test. The mean duration of intravenous fluconazole or itraconazole was 30 days (24-40 days), and that of local application of fluconazole through nasobiliary drainage tube was 19 days (8-24 days). During a follow-up period of 3-42 months, all patient's fungal infection of biliary tract was cured. It is concluded that on the basis of typical clinical features of biliary tract infection, fungal detection of smear/culture of bile obtained by ERCP was the key for the diagnosis of fungal infection of biliary tract. Local application antifungal drug combined with intravenous anti-fungal drugs might be an effective and safe treatment for fungal infection of biliary tract.

    Full Text Available The aim of the study was to evaluate the presence of Mycoplasma bovis infection and co-infections with other Mycoplasma spp. infections in cattle. The tested population was one in the eastern region of Poland containing 66 dairy cows and 23 calves showing different clinical signs and suffering from pneumonia, mastitis, and arthritis. The incidence of M. bovis in co-infections with other Mycoplasma spp. was examined using serological traditional mycoplasma culture methods, and the molecular methods - PCR and polymerase chain reaction/denaturing gradient gel electrophoresis (PCR/DGGE. The PCR/DGGE method for detecting Mycoplasma spp. in cattle was used for the first time in Poland. The seroprevalence of M. bovis in the affected cattle herds in the eastern region of Poland was 47.8% in calves and 19.7% in dairy cows. The direct detection and identification of M. bovis from nasopharyngeal swabs by PCR revealed that 56.5% of calves were positive, but all of the dairy cows were negative. The PCR/DGGE identified eight (34.8% instances of M. arginini and eight (26.1% instances of M. bovirhinis co-infecting with M. bovis in ten calves. The seroprevalence of M. bovis in the tested population was 33.7%. Any future attempts to control mycoplasma infections require an insight into the current epidemiological situation of M. bovis infection and its relationship to other mycoplasmas in causing clinical disease in cattle. Using these diagnostic methods we have demonstrated that mycoplasmal infections are often caused by multiple species of Mycoplasma and not just the primary M. bovis pathogen.

    Vaccination against hepatitis B virus (HBV) immediately after birth prevents neonatal infection by vertical transmission from HBV carrier mothers. There is an ongoing debate whether infant vaccination is sufficient to protect against infection when exposed to HBV later in life. We studied 222 Thai infants born to HBsAg -/+ and HBeAg -/+ mothers who were vaccinated with recombinant hepatitis B vaccine at 0-1-2-12 months of age. A subset of 100 subjects received a booster dose at age 5 years. Blood samples collected yearly for 20 years were examined for anti-HBs antibodies and serological markers of hepatitis B infection (anti-HBc, HBsAg, and in selected cases HBeAg, anti-HBe, HBV DNA). During the 20-year follow-up, no subject acquired new chronic HBV infection or clinical hepatitis B disease. During the first decade, possible subclinical breakthrough HBV infection (anti-HBc seroconversion) was only observed in subjects born to HBsAg +/HBeAg + mothers (6/49 [12.2%]). During the second decade, breakthrough HBV infections were detected in all groups (18/140 [12.8%]). Increases in anti-HBs concentrations that were unrelated to additional HBV vaccination or infection were detected in approximately 10% of subjects in each decade. Primary infant vaccination with a recombinant hepatitis B vaccine confers long-term protection against clinical disease and new chronic hepatitis B infection despite confirmed hepatitis B exposure.

    Insulin degludec (IDeg) is an ultralong acting basal insulin. IDeg has unique pharmacokinetic and pharmacodynamic properties which allow once a daily dosage, at any time of the day. Its use is associated with a significantly lower risk of hypoglycemia. This review discusses the pragmatic use of IDeg, based on available evidence. A complete search of all nine original research papers (BEGIN® clinical trial program) pertaining to IDeg, listed in PubMed, was made to prepare this article.

    Sanford, Rebecca; Cerel, Julie; McGann, Vanessa; Maple, Myfanwy

    2016-07-01

    Over two-thirds of suicide loss survivors, those who have lost a loved one to suicide, seek individual therapy following their loss. However, nothing is known about what survivors find helpful about therapy or how therapy impacts their grief. An online survey was conducted June 2012-March 2013 with a convenience sample of 197 survivors primarily from the USA and Australia to develop a better understanding of treatment seeking loss survivors and their experiences in therapy. Questions explored the experience of the suicide death, the therapy received after the loss, and insights about improving therapy for loss survivors. Participants were generally positive about their therapy experiences. However, respondents endorsed symptoms of PTSD, though many did not report a formal diagnosis from a provider, suggesting a discrepancy that could lead to inadequate treatment of symptoms. The findings provide an understanding of treatment seeking loss survivors, along with implications for therapists treating this population. PMID:27074845

    The objective of this study was to determine cow characteristics and farm management factors during the dry period associated with early postparturient intramammary infection (IMI) and subsequent clinical mastitis (CM). Data were collected three times: before drying off (P1), during the dry period (P2), and 5 to 14 days after calving (P3), using questionnaires and farm investigation. Milk samples were aseptically collected for bacterial identification at P1 and P3. Factors associated with IMI and CM were analyzed using multiple logistic regression models. The final model showed that IMI in early postpartum was significantly associated with full insertion of dry cow antibiotic, dry cows in barns with a combination of tie and free stalls, body condition score (BCS) in dry period and after calving, and milk yield before drying off. For IMI cows, factors significantly associated with clinical expression of mastitis were having daily barn cleaning, teat disinfected with alcohol before administration of dry cow therapy, BCS before drying off, milk yield before drying off, and days in milk at drying off. In conclusion, both cow and farm management factors are associated with the IMI rate and subsequent expression of clinical signs of mastitis in early postpartum cows. PMID:26949960

    The aim of the study was to describe the microbial aetiology of infections from cardiovascular implantable electronic devices (CIEDs) between 2001 and 2014 at The Centro Cuore Morgagni Hospital (Catania, Italy). In this 14-year retrospective study on pacemaker isolates 1,366 patients were evaluated and clinical data were collected. CIEDs were analyzed and isolates tested by routine microbiological techniques. The presence of bacterial biofilm was assessed by means of scanning electron microscopy. Of the patients, fifty-three had catheter-related infections (3.9%), mainly resulting from Staphylococci (4 S. aureus, 32 S. epidermidis, 15 S. hominis, 3 S. haemolyticus, 1 S. warnerii, 1 S. schleiferi, 1 S. lentus and 1 S. capitis) that covered the cardiac catheter with biofilm. Overall, oxacillin-resistance was 55.1%, especially among S. epidermidis, while all isolates were susceptible to vancomycin, teicoplanin, tigecyclin, rifampin, trimethoprim/sulfamethoxazole, linezolid, moxifloxacin, tobramycin and gentamicin. Coagulase-negative staphylococci were the most frequently isolated and S. epidermidis was largely the main single agent. Only four Gram negatives caused polymicrobial infections with Staphylococci. Despite improvements in CIED design and implantation techniques, infection of cardiac devices remains a serious problem. PMID:27367323

    Full Text Available Purpose of the study: Observational studies have noted very high rates of low serum 25-hydroxyvitamin D [25(OHD3] levels in both general and HIV-infected populations. In HIV-infected patients, low 25(OHD3 levels are secondary to a combination of usual risk factors and HIV-specific risk factors, like antiretroviral therapy [1]. The objective of our study is to analyse the magnitude of vitamin D deficiency or insufficiency and the role of various factors such as age, sex, ethnicity, season, and antiretroviral medications in our cohort of HIV-infected patients. Methods: We prospectively collected data on 25-hydroxyvitamin D levels sampled between January 2009 and June 2011 from our cohort of 930 HIV-infected patients. Vitamin D dosage was performed using immunoassay (‘Diasorin’ - Saluggia, Italy. We divided vitamin D levels into 3 categories: 25-hydroxyvitamin D levels <20 mg/nl were considered deficient, insufficient between 20 and 29 ng/ml. Levels ≥30 ng/ml were defined as normal [2]. Data on demographic features (age, ethnicity, season, heterosexuality vs homosexuality, clinical features and laboratory findings (CD4 cell count, viral load, HAART, BMI were collected from patients’ medical records using our institutional database ‘Medical explorer v3r9, 2009’. Summary of results: Overall, 848 patients were included in our study (Table 1. Low levels of serum 25(OHD3 were seen in 89.3% of the study population, from which 69.5% were deficient and 19.8% were insufficient. On univariate analysis, female sex, high BMI, black African, heterosexuality, undetectable viral load and antiretroviral treatment were all predictors of vitamin D deficiency and insufficiency. Treatment with efavirenz and tenofovir were the most associated with low vitamin D levels.

    2008-01-01

    The use of antiretroviral therapy (ART) to treat HIV infection, by restoring CD4+ cell count and immune function, is associated with significant reductions in morbidity and mortality. Soon after ART initiation, there is a rapid phase of restoration of pathogen-specific immunity. In certain patients......, this results in inflammatory responses that may result in clinical deterioration known as 'the immune reconstitution inflammatory syndrome' (IRIS). IRIS may be targeted at viable infective antigens, dead or dying infective antigens, host antigens, tumour antigens and other antigens, giving rise to a...... heterogeneous range of clinical manifestations. The commonest forms of IRIS are associated with mycobacterial infections, fungi and herpes viruses. In most patients, ART should be continued and treatment for the associated condition optimized, and there is anecdotal evidence for the use of corticosteroids in...

    Dealing with emotions is a critical feature of professional behaviour. There are no comprehensive theoretical models, however, explaining how medical students learn about emotions. We aimed to explore factors affecting their emotions and how they learn to deal with emotions in themselves and others. During a first-year nursing attachment in hospitals and nursing homes, students wrote daily about their most impressive experiences, explicitly reporting what they felt, thought, and did. In a subsequent interview, they discussed those experiences in greater detail. Following a grounded theory approach, we conducted a constant comparative analysis, collecting and then interpreting data, and allowing the interpretation to inform subsequent data collection. Impressive experiences set up tensions, which gave rise to strong emotions. We identified four 'axes' along which tensions were experienced: 'idealism versus reality', 'critical distance versus adaptation', 'involvement versus detachment' and 'feeling versus displaying'. We found many factors, which influenced how respondents relieved those tensions. Their personal attributes and social relationships both inside and outside the medical community were important ones. Respondents' positions along the different dimensions, as determined by the balance between attributes and tensions, shaped their learning outcomes. Medical students' emotional development occurs through active participation in medical practice and having impressive experiences within relationships with patients and others on wards. Tensions along four dimensions give rise to strong emotions. Gaining insight into the many conditions that influence students' learning about emotions might support educators and supervisors in fostering medical students' emotional and professional development.

  7. Toxoplasmosis can be a sexually transmitted infection with serious clinical consequences. Not all routes of infection are created equal.

    Science.gov (United States)

    Flegr, J; Klapilová, K; Kaňková, S

    2014-09-01

    Toxoplasma gondii infects about 30% of the human population. Common sources of infection are oocysts in cat faeces contaminating drinking water or unwashed vegetables, undercooked meat containing tissue cysts, and organ transplants from infected donors containing tissue cysts. However, very often, it is not possible to identify any potential source of infection in mothers of children with congenital toxoplasmosis. Here we present a hypothesis suggesting that toxoplasmosis is transmitted from infected men to noninfected women during unprotected sexual intercourse, which can result in the most serious form of disease, congenital toxoplasmosis. Arguments for the hypothesis: (1) Toxoplasma tachyzoites are present in the seminal fluid and tissue of the testes of various animals including humans. In some species infection of females by artificial insemination with semen from infected males has been observed. (2) Up to two thirds of Toxoplasma infections in pregnant women cannot be explained by the known risk factors. (3) Prevalence of toxoplasmosis in women in child-bearing age covaries with the incidence of sexually transmitted diseases in particular countries. (4) In some countries, an increased incidence of toxoplasmosis has been reported in women (but not men) aged 25-35 years. This second peak of infection could be associated with women having regular unprotected sex after marriage. (5) Toxoplasmosis triggers schizophrenia in predisposed subjects. Onset of schizophrenia is about 2-3 years earlier in men than in women. However, this difference in the onset can be found only between Toxoplasma-infected patients. The increased onset of schizophrenia in infected women could be associated with the already mentioned second peak of toxoplasmosis incidence. (6) The prevalence of toxoplasmosis decreases in developed countries in last 20 years. This trend could be a result of decrease in promiscuity and increase in safe sex practices, both associated with the AIDS pandemics

  8. Pathophysiology, clinical manifestation and management of angioedema - our experience

    2015-01-01

    Full Text Available Introduction. Angioedema is characterized by subcutaneous and/or submucosal swelling usually localized to the lips, eyelids, tongue, oral cavity, larynx and pharynx. Various types of angioedema, caused by different pathophysiologic mechanisms, can have the same or very similar clinical picture and require different diagnostic and therapeutic procedures. The immediate threat to life as a result of rapidly developed edema of the pharynx and larynx with airway obstruction requires endotracheal intubation or emergency tracheotomy. Standard therapy, which includes epinephrine, second-generation antihistamines and steroids, is not effective in the treatment of all types of angioedema. Objective. On the basis of the clinical presentation and course of angioedema, this retrospective study was aimed at contributing to a better understanding of the etiopathogenesis of the disease and at helping determine the most effective available treatment modalities. Methods. This retrospective study included patients treated under the diagnosis of angioedema of the upper aerodigestive tract between 2000 and 2012 in the Department of Otorhinolaryngology, Clinical Center of Banja Luka. Results. A total of 76 subjects were included in the study. The average age was 62.8 years. There were 40 (52.6% male and 36 (47.4% female patients. The largest number of patients (44.7% had type II angioedema. Almost half of the patients or 36 patients (47.4% were on treatment with an angiotensinconverting enzyme inhibitor (ACEi, but there was no statistically significant difference under the total number of patients (p=0.678. Conclusion. Better understanding of pathophysiologic mechanisms and the adoption of diagnostic protocols contributes to more effective treatment of angioedema.

    International Nuclear Information System (INIS)

    With a radioreceptorassay (THYBIA-assay) autoantibodies against TSH-receptors were determined among 17 patients with untreated toxic diffuse goiters and in 50 patients with non immunogenic thyroid diseases (33 healthy controls, respectively patients with euthyroid diffuse or nodular goiters as well as 17 patients with toxic regional autonomy). The upper limit of normal is a THYBIA-titer F = 20%. According to the good correlation of positive THYBIA-titers with Graves' ophthalmopathy, clinical secondary criterias and the results of another radioreceptorassays (TRAK-assay) the tested radioreceptorassay seems to be useful in the differentiation of immunogenic and non immunogenic toxic diffuse goiter.

  18. Opportunities and Possibilities from Illness: Volunteer Experiences among People Infected with HIV/AIDS

    Directory of Open Access Journals (Sweden)

    Lirio del Carmen Gutiérrez Rivera

    2007-07-01

    Full Text Available All illnesses can be interpreted. In the case of HIV/AIDS, experience and interpretation are intercepted by meanings that recluse, insulate and morally expose patients and their social networks. Volunteers stand out in these networks, because they are the only ones that continue to have contact with patients. In many cases, they are stigmatized. This article is about the experience of female volunteers with people infected with HIV/AIDS. The phenomenological experience allows studying their perceptions, verifications and modifications of the disease. The results show the following: first, HIV/AIDS is an opportunity to thank a past event; second, it is an opportunity to construct, through altruism, a space of opportunity for them and their patients; third, HIV/AIDS shows social shortages. Although this experience does not construct political identities or legal discourse, it confronts and inverts negative perceptions of the disease through actions of care whose essential component is love, altruism and brotherhood.

    2014-01-01

    Full Text Available Severe fever with thrombocytopenia syndrome (SFTS is an emerging infectious and hemorrhagic disease recently described in China and western Japan. A 71-year-old healthy Japanese woman noticed a tick biting her after harvesting in an orchard and removed it herself. She developed diarrhea, anorexia, and chills eight days later. Because these symptoms continued, she visited a primary care physician 6 days after the onset. Laboratory data revealed thrombocytopenia, leukocytopenia, and elevated liver enzymes. She was then referred to our hospital. Although not completely fulfilling the diagnostic criteria used in a retrospective study in Japan, SFTS was suspected, and we detected SFTS virus in the patient’s blood using RT-PCR. However, she recovered without intensive treatment and severe complications 13 days after the onset. In this report, we present a mild clinical course of SFTS virus infection in Japan in detail.

Previous studies in Nepal have highlighted the importance of murine typhus as a cause of febrile illness in adults and enteric fever as a leading bacterial cause of fever among children admitted to hospital. METHODS: We prospectively studied a total of 1084 febrile children aged between 2 months and 14 years presenting to a general hospital outpatient department in Kathmandu Valley, Nepal, over two study periods (summer and winter. Blood from all patients was tested by conventional culture and by real-time PCR for Rickettsia typhi. RESULTS: Putative etiological agents for fever were identified in 164 (15% patients. Salmonella enterica serovar Typhi (S. Typhi was identified in 107 (10%, S. enterica serovar Paratyphi A (S. Paratyphi in 30 (3%, Streptococcus pneumoniae in 6 (0.6%, S. enterica serovar Typhimurium in 2 (0.2%, Haemophilus influenzae type b in 1 (0.1%, and Escherichia coli in 1 (0.1% patient. S. Typhi was the most common organism isolated from blood during both summer and winter. Twenty-two (2% patients were PCR positive for R. typhi. No significant demographic, clinical and laboratory features distinguished culture positive enteric fever and murine typhus. CONCLUSIONS: Salmonella infections are the leading cause of bloodstream infection among pediatric outpatients with fever in Kathmandu Valley. Extension of immunization programs against invasive bacterial disease to include the agents of enteric fever and pneumococcus could improve the health of children in Nepal.

    The diagnosis of neurosyphilis (NS) is a challenge, especially in HIV-infected patients, and the criteria for deciding when to perform a lumbar puncture (LP) in HIV-infected patients with syphilis are controversial. We retrospectively reviewed demographic, clinical, and laboratory data from 122 cases of HIV-infected patients with documented early syphilis who underwent an LP to rule out NS, and we evaluated 3 laboratory-developed validated real-time PCR assays, the Treponema pallidum particle agglutination (TPPA) assay, the fluorescent treponemal antibody absorption (FTA-ABS) assay, and the line immunoassay INNO-LIA Syphilis, for the diagnosis of NS from cerebrospinal fluid (CSF) samples of these patients. NS was defined by a reactive CSF-VDRL test result and/or a CSF white blood cell (WBC) count of >20 cells/μl. Thirty of the 122 patients (24.6%) had early NS. Headache, visual symptoms, a CD4 cell count of RPR) titers were not associated with early NS (P = 0.575). For the diagnosis of NS, the PCR, FTA-ABS, TPPA, and INNO-LIA assays had sensitivities of 58%, 100%, 68%, and 100%, specificities of 67%, 12%, 49%, and 13%, and negative predictive values of 85%, 100%, 84%, and 100%, respectively. Visual disturbances, headache, uncontrolled HIV-1 viremia, and a CD4 cell count of syphilis, while blood serum RPR titers were not; therefore, RPR titers should not be used as the sole criterion for deciding whether to perform an LP in early syphilis. When applied to CSF samples, the INNO-LIA Syphilis assay easily helped rule out NS. PMID:24088852

    Full Text Available ABSTRACT Oral infections are caused by an imbalance in the patient’s indigenous flora which changes from commensal to opportunistic. Odontogenic infections are the most common reason for consultation in children and adolescents. Rational use of antibiotics is the best strategy to avoid microbial resistance. Dental infections should first receive proper local treatment, which can also be complemented with a systemic method. Appropriate drug selection and dosing should be made. Amoxicilin is the first choice for antimicrobial agents in pediatric dentistry. Clindamycin and clarithromycin are the best alternative for patients with penicillin hypersensibility. In this literature review, the authors intended to establish clear clinical management guidelines for emergency treatment and subsequent final resolution. RESUMEN Las infecciones bucales son producidas por un desequilibrio de la flora indígena del paciente que pasa de comensal a oportunista. Las consultas más frecuentes en niños y adolescentes son las infecciones odontogénicas. El uso racional de antibióticos, es la estrategia más importante para evitar la resistencia microbiana. Las infecciones dentarias deben recibir en primera instancia el tratamiento local correspondiente y a veces complementarse con tratamiento sistémico seleccionando y dosificando adecuadamente el fármaco. El antimicrobiano de primera elección en odontopediatría es la amoxicilina y para pacientes con hipersensibilidad a las penicilinas, se indican claritromicina o clindamicina. Esta revisión de la literatura busca establecer pautas de manejo clínico claras para el tratamiento de urgencia y su posterior resolución definitiva.

    In this prospective clinical study on 40 patients with similar clinical conditions (edentulous jaw with 2 interforaminal implants) commercially available ceramic ball attachments (ruby) were compared to commercial titanium ball attachments. The primary aim of the study was to measure the wear of the ball attachments after being 1 year in function. However, in the course of the study already after 7 to 12 months multiple failures with ceramic ball attachments occurred. Twelve (28%) of 43 ceramic ball attachments had to be replaced, mostly because of fractures (8) of the ceramic ball. It seems that ceramic ball attachments of the investigated design are not able to withstand normal intraoral stresses. The short-term susceptibility to fractures didn't allow to examine the ceramic-inherent features such as compressive strength and wear resistance. Furthermore, a secure connection between a titan base and a ceramic ball seems to be challenging. Based on these results, in implant-retained removable prosthesis the use of metal-based retainers is still recommended, although during maintenance a higher wear has to be expected. This wear can be compensated by either activating or changing the matrix or the patrix. PMID:18293602

  6. Clinical experience for radiolucent stones; A report of 27 cases

    International Nuclear Information System (INIS)

    The cause of radiolucent filling defects in the upper urinary tract are malignant tumor, radiolucent stones, blood clots, air bubbles, congenital deformities of renal parenchyme, and various specific and non-specific infection and their sequence. So the differential diagnosis between malignancy and radiolucent stones is very important, and the exact and fast diagnosis of radiolucent stones is useful in excluding the possibility of malignancy. 27 cases with radiolucent stones were evaluated retrospectively for exact diagnosis and appropriate treatment method. Intravenous urography was done in all cases, and retrograde pyelography, ultrasonography, computed tomography and/or ureterorenoscopy were performed for diagnosis, if needed. Size of stones were measured below 10mm by transverse length in 19 cases (70.4%) with a range of 3 to 30mm. The locations of stones were pelvicalyceal system in 8 cases (29.6%) and ureter in 19 cases (70.4%). Among the diagnostic methods, computed tomography was used most frequency. ESWL with retrograde pyelography was most frequent used method of treatment, also simple hydration to small stone was effective. (author)

    Full Text Available Introduction. Problem of drug-induced allergic reaction is especially actual both in well-developing countries as well as in countries of Eastern European region. By the WHO data, distribution of allergy is up to 30 %, and main reasons for that are increasing of pharmaceuticals consumption by a person, change of nutrition style towards more chemicals synthetic substitutions. Generally, a quantity of Europeans with allergy reach 150 mln. Reactions of hypersensitivity to medications is so serious discussion question among physicians and their patients, since it is the most important reason to stop treatment and for refuse remedies. Authors hope, that presenting here clinical material will bring benefit both clinicians and patients like cases of drug-induced allergic reactions due to self-prescribed treatment (antipyretics, antibiotics. Thus, this research paper aimed to analyze the clinical cases of drug-induced allergy in patients with acute respiratory illnesses, which had admitted to Infectious diseases department of Municipal Clinical Hospital of Chernivtsi city (Ukraine.

    Full Text Available Danielle M Robertson, H Dwight CavanaghDepartment of Ophthalmology, The University of Texas Southwestern Medical Center, Dallas, TX, USAAbstract: Microbial keratitis (MK is the most visually devastating complication associated with contact lens wear. Pseudomonas aeruginosa (PA is highly invasive in the corneal epithelium and is responsible for more than half of the reported cases of contact lens-related MK. To protect against Pseudomonas-mediated MK, the corneal epithelium has evolved overlapping defense mechanisms that function to protect the ocular surface from microbial invasion. Research has shown that contact lens wear disrupts these protective mechanisms through breakdown of normal homeostatic surface renewal as well as damaging the corneal surface, exposing underlying cell membrane receptors that bind and internalize PA through the formation of lipid rafts. Human clinical trials have shown that initial adherence of PA with resulting increased risk for microbial infection is mediated in part by contact lens oxygen transmissibility. Recently, chemical preserved multipurpose solutions (MPS have been implicated in increasing PA adherence to corneal epithelial cells, in addition to inducing significant levels of toxic staining when used in conjunction with specific silicone hydrogel lenses. This review summarizes what is currently known about the relationship between contact lenses, the corneal epithelium, MPS, and infection.Keywords: cornea, epithelium, contact lens, microbial keratitis

    The introduction of potent combination antiretroviral therapy (cART) has had a remarkable impact on the natural history of HIV infection, leading to a dramatic decline in the mortality rate and a considerable increase in the life expectancy of HIV-positive people. However, cART use is frequently associated with several metabolic complications, mostly represented by lipid metabolism alterations, which are reported very frequently among persons treated with antiretroviral agents. In particular, hyperlipidaemia occurs in up to 70%-80% of HIV-positive subjects receiving cART and is mainly associated with specific antiretroviral drugs belonging to three classes of antiretroviral agents: NRTIs, NNRTIs and PIs. The potential long-term consequences of cART-associated dyslipidaemia are not completely understood, but an increased risk of premature coronary heart disease has been reported in HIV-infected patients on cART, so prompt correction of lipid metabolism abnormalities is mandatory in this population. Dietary changes, regular aerobic exercise and switching to a different antiretroviral regimen associated with a more favourable metabolic profile are the first steps in clinical management, but lipid-lowering therapy with fibrates or statins is often required. In this case, the choice of hypolipidaemic drugs should take into account the potential pharmacokinetic interactions with many antiretroviral agents. PMID:26846208

    Full Text Available Description of two clinical cases of chronic HBV hepatitis at cirrhotic stage associated with type III cryoglobulinemia manifested with symptoms of systemic vasculitis is presented in current article. There were no signs of HCV infection in both patients. In first case cutaneous vasulitis appeared after 19 years since serological finding of HBsAg and vasculitis progressed despite steroid therapy. Initiation of antiviral therapy (entecavir 0.5 g/day induced transient remission. After interruption of antiviral therapy vasculitis reappeared with several vasculitic ulcers on lower legs. Mild improvement of vasculitis was noted after repeated plasmapheresis, steroid and cytostatic treatment with addition of lamivudin. Despite therapy reactivation of HBV infection was detected. Lamivudin was changed to entecavir and rituximab was given in two 500 mg infusions. Combined antiviral and anti-CD20 treatment induced remission of cutaneous vasculitis and healing of leg ulcers. In other case vasculitis manifested after 21 years since detection of HBsAg with cutaneous purpura, arthritis and microhematuria. Entecavir 0.5 g/day induced rapid virological response and complete remission of symptoms related to vasculitis. Similar literature cases were reviewed and available treatment options in refractory cryoglobulinemic vasculitis were discussed.

    Results: On comparison of clinical signs in different dengue subgroups it was observed that the mean value of pulse, blood pressure and respiratory rate were significantly more deranged in the DSS group as compared to the DF group. Platelet count was significantly lower in all the sub groups whereas PT/aPTT was more dearranged in the DSS and DHF group as compared to the DF group. Comparison between the mean values of liver function test in different dengue sub groups had been shown, elevated transaminases, hypoproteinaemia and hypoalbuminaemia, in higher frequency in dengue haemorrhagic fever (DHF and dengue shock syndrome (DSS as compared to classical dengue fever (DF (P values significant. SGOT was significantly higher than the SGPT levels and SGOT was much more elevated in the DSS sub group compared to the DFS and DF group. Conclusions: The liver enzymes serum aminotransferase levels were significantly raised in patients with dengue shock syndrome compared to other two groups. Serum aminotransferases directly correlate with severity of infection in all the sub groups. Patients with secondary dengue infection were more prone for developing bleeding manifestations and shock syndrome. [Int J Res Med Sci 2016; 4(3.000: 743-748

    Full Text Available BACKGROUND: Urinary tract infections (UTIs in elderly patients can be a complex problem in terms of approach to diagnosis, treatment, and prevention, because the patients often present nonspecific symptoms. The epidemiological and clinical characteristics of UTI in elderly women were studied, in order to make early diagnosis and prevent serious clinical complications secondary to UTI. METHODS: This was a prospective population-based study, with elderly women, during their first medical office visit. Medical records were obtained by clinical history and physical examination in order to detect signs and symptoms of UTI and the presence of comorbidities. Clean-catch midstream urine specimens for urinary dipstick test, sediment, and culture were collected; cervical samples for conventional Pap smears were also collected. RESULTS: UTI was found in 16.55% of elderly women. The most frequent urinary symptom was foul smelling urine, in 60.6%. E. coli was responsible for 98 (76.56% cases of significant bacteriuria; 34 (34.69% were resistant to trimethoprim-sulfamethoxazole, and 21 (21.42% to fluoroquinolones. Asymptomatic bacteriuria (AB was not treated. The presence of predisposing factors demonstrated that the history of previous UTI (p < 0.001, vaginitis (p < 0.001, and diabetes (p = 0.042 increased the risk for UTI. CONCLUSION: This study confirmed the high prevalence of UTI among elderly women and its unusual clinical presentation. Diabetes, history of previous UTI, and vaginitis were shown to be predisposing factors for UTI; it is not necessary to treat AB in elderly women, even among diabetics.

    Full Text Available Abstract Background The tcdA-negative variant (A-B+ of Clostridium difficile is prevalent in East Asian countries. However, the risk factors and clinical characteristics of A-B+C. difficile infections (CDI are not clearly documented. The objective of this study was to investigate these characteristics. Methods From September 2008 through January 2010, the clinical characteristics, medication history and treatment outcomes of CDI patients were recorded prospectively. Toxin characterization and antibiotic susceptibility tests were performed on stool isolates of C. difficile. Results During the study period, we identified 22 cases of CDI caused by tcdA-negative tcdB-positive (A-B+ strains and 105 cases caused by tcdA-positive tcdB-positive (A+B+ strains. There was no significant difference in disease severity or clinical characteristics between the two groups. Previous use of clindamycin and young age were identified as significant risk factors for the acquisition of A-B+ CDI (OR = 4.738, 95% CI 1.48–15.157, p = 0.009 and OR = 0.966, 95% CI 0.935–0.998, p = 0.038, respectively in logistic regression. Rates of resistance to clindamycin were 100% and 69.6% in the A-B+ and A+B+ isolates, respectively (p = 0.006, and the ermB gene was identified in 17 of 21 A-B+ isolates (81%. Resistance to moxifloxacin was also more frequent in the A-B+ than in the A+B+ isolates (95.2% vs. 63.7%, p = 0.004. Conclusions The clinical course of A-B+ CDI is not different from that of A+B+ CDI. Clindamycin use is a significant risk factor for the acquisition of tcdA-negative variant strains.

    Full Text Available BACKGROUND: No comprehensive analysis is available on the viral etiology and clinical characterization among children with severe acute respiratory infection (SARI in China during 2009 H1N1 pandemic and post-pandemic period. METHODS: Cohort of 370 hospitalized children (1 to 72 months with SARI from May 2008 to March 2010 was enrolled in this study. Nasopharyngeal aspirate (NPA specimens were tested by a commercial assay for 18 respiratory viral targets. The viral distribution and its association with clinical character were statistically analyzed. RESULTS: Viral pathogen was detected in 350 (94.29% of children with SARI. Overall, the most popular viruses were: enterovirus/rhinovirus (EV/RV (54.05%, respiratory syncytial virus (RSV (51.08%, human bocavirus (BoCA (33.78%, human parainfluenzaviruse type 3 (PIV3 (15.41%, and adenovirus (ADV (12.97%. Pandemic H1N1 was the dominant influenza virus (IFV but was only detected in 20 (5.41% of children. Moreover, detection rate of RSV and human metapneumovirus (hMPV among suburb participants were significantly higher than that of urban area (P<0.05. Incidence of VSARI among suburb participants was also significant higher, especially among those of 24 to 59 months group (P<0.05. CONCLUSION: Piconaviruses (EV/RV and paramyxoviruses are the most popular viral pathogens among children with SARI in this study. RSV and hMPV significantly increase the risk of SARI, especially in children younger than 24 months. Higher incidence of VSARI and more susceptibilities to RSV and hMPV infections were found in suburban patients.

    Comparative effectiveness research (CER) is not new but its potential to improve the effectiveness of healthcare has not yet been exploited in the US. Other countries such as the UK have more experience of this. Key points of the UK experience are summarized here and some possible pointers for the US are drawn. These include the following: how to go beyond the evidence and apply judgements to make recommendations with authority and in a timely manner; how to implement these recommendations; how to identify suitable topics; and how to be open and transparently fair to all stakeholders. The quality of the science of CER is key but this needs developing, and not just in biomedical or statistical terms but also in how to understand public expectations, and how to implement its recommendations. A key issue is the role of health economics, which seems to have been marginalized by the CER legislation, but perhaps this is more apparent than real. Clearly this is a matter for much further debate. It is hard to see how CER can deliver its potential without active consideration of both benefits and costs. Although other countries have more experience of this than does the US, the context for such work is always very specific and the US will have to find its own way, while trying to avoid some of the errors made elsewhere.

    The purpose of this study was to compare clinical features of Clostridium difficile infection (CDI) to toxin gene profiles of the strains isolated from Danish hospitalized patients. C. difficile isolates were characterized by PCR based molecular typing methods including toxin gene profiling and analysis of deletions and truncating mutations in the toxin regulating gene tcdC. Clinical features were obtained by questionnaire. Thirty percent of the CDI cases were classified as community-acquired. Infection by C. difficile with genes encoding both toxin A, toxin B and the binary toxin was significantly associated with hospital-acquired/healthcare-associated CDI compared to community-acquired CDI. Significantly higher leukocyte counts and more severe clinical manifestations were observed in patients infected by C. difficile containing genes also encoding the binary toxin together with toxin A and B compared to patients infected by C. difficile harbouring only toxin A and B. In conclusion, infection by C. difficile harbouring genes encoding both toxin A, toxin B and the binary toxin were associated with hospital acquisition, higher leukocyte counts and severe clinical disease.

    Full Text Available Abstract Background Control of sexually transmitted infections (STIs is an important part of the effort to reduce the risk of HIV/AIDS. STI clinics in the government hospitals in India provide services predominantly to the poor. Data on the cost and efficiency of providing STI services in India are not available to help guide efficient use of public resources for these services. Methods Standardised methods were used to obtain detailed cost and output data for the 2003–2004 fiscal year from written records and interviews in 14 government STI clinics in the Indian state of Andhra Pradesh. The economic cost per patient receiving STI treatment was calculated, and the variations of total and unit costs across the STI clinics analysed. Multivariate regression technique was used to estimate incremental unit costs. The optimal number of STIs that could be handled by the clinics was estimated. Results 18807 STIs were diagnosed and treated at the 14 STI clinics in fiscal year 2003–2004 (range 323–2784, median 1199. The economic cost of treating each STI varied 5-fold from Indian Rupees (INR 225.5 (US$ 4.91 to INR 1201.5 (US$ 26.15 between 13 clinics, with one other clinic having a very high cost of INR 2478.5 (US$ 53.94. The average cost per STI treated for all 14 clinics combined was INR 729.5 (US$ 15.88. Personnel salaries made up 76.2% of the total cost. The number of STIs treated per doctor full-time equivalent and cost-efficiency for each STI treated had a significant direct non-linear relation (p 2 = 0.81; power function. With a multiple regression model, apart from the fixed costs, the incremental cost for each STI detected and cost of treatment was INR 55.57 (US$ 1.21 and for each follow-up visit was INR 3.75 (US$ 0.08. Based on estimates of optimal STI cases that could be handled without compromising quality by each doctor full-time equivalent available, it was projected that at 8 of the 14 clinics substantially more STI cases could be

    Invasive Candida infections contribute to significant morbidity and mortality in patients with healthcare-associated infections. They represent a major burden on the public health system, and are challenging to diagnose and treat. A multidisciplinary expert panel critically reviewed available evidence to provide consensus recommendations for the management of invasive Candida infections in the Middle East. Based on diagnosis, recommendations were provided for the management of Candida infections in non-neutropenic and neutropenic patients. Polyenes (amphotericin B-deoxycholate [AmB-d] and lipid formulations amphotericin B [LFAmB]), triazoles (fluconazole, itraconazole and voriconazole), echinocandins (caspofungin, anidulafungin, and micafungin) and flucytosine are the recommended categories of antifungal agents for treatment of Candida infections. Echinocandins are preferred for treatment of proven and suspected Candida infections, especially in critically ill patients or those with previous exposure to azoles. Recommendations were also provided for infections caused by specific Candida species as well as management of different disease conditions. The experts highlighted that the guidelines should be used along with clinical judgment. Given the paucity of published data from the region, research in the form of randomized clinical trials should be given priority. PMID:24035607

    @@ Naokong (GB19) is located 1.5 cun above Fengchi (GB20) and at the level with Naohu (GV17) in the depression of the lateral side of the external occipital protuberance. It belongs to the Gallbladder Channel of Foot Shaoyang, and is a crossing point of the Foot Shaoyang Channel and the Yangwei Channel. As is said in A Collection of Gems in Acupuncture and Moxibustion, Naokong (GB19) is indicated for emaciation due to over strain and stress, fever, neck rigidity, unbearable pain in the head, heavy eyes and palpitation as well as xenophthalmia and rhinalgia caused by epileptic seizure in severe cases. In clinical practice, the author has adopted Naokong (GB 19) as the main point in treating some obstinate diseases and obtained quite good therapeutic effects.

    This report demonstrates that using interferon gamma release assays to screen for latent tuberculosis infection in female commercial sex workers in an outreach sexual health clinic is feasible and acceptable. Routine interferon gamma release assay use successfully identified high numbers of latent tuberculosis infection. Innovative approaches to treatment and follow up were required to improve treatment adherence in this group. Direct observation of therapy within the sexual health clinic was also feasible. Successful follow up was dependent on the support of outreach workers, interpreters and tuberculosis nurses. PMID:26589629

    Full Text Available A 59-year-old female patient with mitral valve prolapse and a previous history of lumbosacral spondyloarthrosis and lumbar disk hernia had an episode of infective endocarditis due to Streptococcus viridans, which evolved with peripheral embolism to the left kidney, spleen, and left iliac artery, and intraventricular cerebral hemorrhage. Her clinical manifestations were low back pain and hematuria, which were initially attributed to an osteoarticular condition. Infective endocarditis is a severe polymorphic disease with multiple clinical manifestations and it should always be included in the differential diagnosis by clinicians.

    Men who have sex with men (MSM) have higher rates of poor sexual health. The National Institute for Health and Care Excellence has produced guidance on increasing the uptake of HIV testing to reduce undiagnosed infection in MSM. We report the results of a pilot outreach sexually transmitted infection service using nurse-delivered screening and self-sampled postal testing at a sex on premises venue with comparison made against a sexual health clinic service. Thirty men were included in each group. Users of the nurse-delivered and postal services were older (nurse service median age 57.5 years vs. postal kit service 47 years vs. clinic 35.5 years, p ≤ 0.001). Outreach groups were less likely to have undertaken sexually transmitted infection testing previously than the clinic group (53.3% and 60% vs. 93.3%, p ≤ 0.001). Chlamydia trachomatis and Neisseria gonorrhoeae testing uptake was comparable across groups (nurse outreach 86.6%, 'do it yourself' postal kit 100% vs. clinic 100%, p = 0.032), but uptake for blood tests was lower in the postal kit group (nurse outreach 83.3%, postal kit 53.3% vs. clinic 100%, p ≤ 0.001). No significant difference in active sexually transmitted infection positivity across the groups was observed. This combination outreach screening approach is effective in targeting MSM who use sex on premises venues. PMID:24912535

    This article summarizes the experience with the development of clinical pharmacy services in the Ghent University Hospital in Belgium. Implementation of clinical pharmacy services in Belgian hospitals has not been evident because these activities were initially not structurally financed. The aim is to describe the strengths and weaknesses of the clinical pharmacy development process, and the milestones that enhanced the progress. Furthermore, the organisation of clinical pharmacy in the Ghent University Hospital is explained, including back- and front-office activities, seamless pharmaceutical care and medication safety improvement. Some working methods, procedures and tools are explained for different clinical pharmacy services. In particular, the clinical pharmacy projects for geriatric patients as well as the preparation of clinical pharmacy services for the accreditation process are explained. We also reflect on the organisation model and the future development of clinical pharmacy, taking into consideration facilitators and potential barriers. PMID:26922733

    Mandatory in several countries, in vivo dosimetry has been recognized as one of the next milestones in radiation oncology. Our department has implemented clinically an EPID based in vivo dosimetry system, EPIgray, by DOSISOFT S.A., since 2006. An analysis of the measurements per linac and energy over a two-year period was performed, which included a more detailed examination per technique and treat-ment site over a six-month period. A comparison of the treatment planning system doses and the doses estimated by EPIgray shows a mean of the differences of 1.9% (± 5.2%) for the two-year period. The 3D conformal treatment plans had a mean dose difference of 2.0% (± 4.9%), while for intensity-modulated radiotherapy and volumetric-modulated arc therapy treatments the mean dose difference was -3.0 (± 5.3%) and -2.5 (± 5.2%), respectively. In addition, root cause analyses were conducted on the in vivo dosimetry measurements of two breast cancer treatment techniques, as well as prostate treatments with intensity-modulated radiotherapy and volumetric-modulated arc therapy. During the breast study, the dose differences of breast treatments in supine position were correlated to patient setup and EPID positioning errors. Based on these observations, an automatic image shift correc-tion algorithm is developed by DOSIsoft S.A. The prostate study revealed that beams and arcs with out-of-tolerance in vivo dosimetry results tend to have more complex modulation and a lower exposure of the points of interest. The statistical studies indicate that in vivo dosimetry with EPIgray has been successfully imple-mented for classical and complex techniques in clinical routine at our institution. The additional breast and prostate studies exhibit the prospects of EPIgray as an easy supplementary quality assurance tool. The validation, the automatization, and the reduction of false-positive results represent an important step toward adaptive radiotherapy with EPIgray. PMID:27167283

    Overprescribing of antibiotics for acute respiratory infections (ARIs) is common. Our objective was to develop and validate a vignette-based method to estimate clinician ARI antibiotic prescribing. We surveyed physicians (n = 78) and retail clinic clinicians (n = 109) between January and September 2013. We surveyed clinicians using a set of ARI vignettes and linked the responses to electronic health record data for all ARI visits managed by these clinicians during 2012. We then created a new measure of antibiotic prescribing, the comprehensive ARI management rate. This was defined as not prescribing antibiotics for antibiotic-inappropriate diagnoses and prescribing guideline-concordant antibiotics for antibiotic-appropriate diagnoses (and also included appropriate use of streptococcal testing for the pharyngitis vignettes). We compared the vignette-based and chart-based comprehensive ARI management at the clinician level. We then identified the combination of vignettes that best predicted comprehensive ARI management rates, using a partitioning algorithm. Responses to 3 vignettes partitioned clinicians into 4 groups with chart-based comprehensive ARI management rates of 61% (n = 121), 50% (n = 47), 31% (n = 12), and 22% (n = 7). Responses to 3 clinical vignettes can identify clinicians with relatively poor quality ARI antibiotic prescribing. Vignettes may be a mechanism to target clinicians for quality improvement efforts.

    Full Text Available Evidence-based techniques have been increasingly used in the creation of clinical guidelines and the development of recommendations for medical practice. The use of levels of evidence allows the reader to identify the quality of scientific information that supports the recommendations made by experts. The objective of this review was to address current concepts related to the clinical impact, diagnosis, and treatment of Pseudomonas aeruginosa infections in patients with cystic fibrosis. For the preparation of this review, the authors defined a group of questions that would be answered in accordance with the principles of PICO–an acronym based on questions regarding the Patients of interest, Intervention being studied, Comparison of the intervention, and Outcome of interest. For each question, a structured review of the literature was performed using the Medline database in order to identify the studies with the methodological design most appropriate to answering the question. The questions were designed so that each of the authors could write a response. A first draft was prepared and discussed by the group. Recommendations were then made on the basis of the level of scientific evidence, in accordance with the classification system devised by the Oxford Centre for Evidence-Based Medicine, as well as the level of agreement among the members of the group.

    Cystinuria is an inherited autosomal recessive disease with a prevalence 1:7000 and typical age of onset in the second decade of life. This nephrolithiasis is not always well known and well studied and for this reason it is often underdiagnosed. Cystinuria is characterized by increased urinary excretion of cystine and dibasic amino acids (lysine, ornithine, arginine) caused by defective transport of these amino acids across the luminal membrane of proximal tubule and small intestine cells. Two mutated genes responsible of this tubular defect are SLC3A1 on chromosome 2 and SLC7A9 on chromosome 19. Clinical manifestations of cystinuria are essentially those related to stones formation and their movement across the urinary tract, like flank pain/abdomen pain and hematuria, as occurred in other nephrolithiasis types. Diagnosis is based on biochemical urine analysis, stone analysis and imaging. Genetic study of this disease may be a new and stimulating approach to better understand the defects and identify new therapeutic targets. A wider knowledge and a more detailed approach to cystinuria may help to ameliorate patients quality of life, to prevent recurrences and complications and to develop more specific and adequate treatments.

    Endoscopic forehead lift is a well-established procedure in aesthetic plastic surgery. Many agree that currently available video-endoscopic equipment is bulky, multipieced and sometimes cumbersome in the operating theater. A novel system, the Universal Serial Bus Endoscope (USBE) was designed to simplify and reduce the number of necessary equipment pieces in the endoscopic setup. The USBE is attached by a single cable to a Universal Serial Bus (USB) port of a laptop computer. A built-in miniaturized cold light source provides illumination. A built-in digital camera chip enables procedure recording. The real-time images and movies obtained with USBE are displayed on the computer's screen and recorded on the laptop's hard disk drive. In this study, 25 patients underwent endoscopic browlift using the USBE system to test its clinical usefulness, all with good results and without complications or need for revision. The USBE was found to be reliable and easier to use than current video-endoscope equipment. The operative time needed to complete the procedure by the authors was reduced approximately 50%. The design and main technical characteristics of the USBE are presented. PMID:15383889

    Full Text Available Considering the academic development of the psychologist as a complex process which articulates the transmission of scientific knowledge and changes in imaginative activity, we psychoanalytically investigate the collective imaginary of Psychology students regarding the first clinical consultation. We conducted a group interview with 52 undergraduate students, using the Thematic Story-Drawing Procedure as a way to open a dialogical field. The material obtained, through the psychoanalytical method, resulted in the creation/gathering of four affective-emotional meaning fields: “I came, I saw and I conquered”, “I know that I (do not know”, “I survived and I will save” and “I am and I do”, from which we see an emotionally immature imaginary about the meeting with the patient, since students are more self-centered than concerned with the patient. The overall situation indicates the need for care regarding student academic development, in order to encourage a more mature approach toward the suffering of the other.

    Motor imagery is suggested to stimulate the same plastic mechanisms in the brain as a real movement. The brain-computer interface (BCI) controls motor imagery by converting EEG during this process into the commands for an external device. This article presents the results of two-stage study of the clinical use of non-invasive BCI in the rehabilitation of patients with severe hemiparesis caused by focal brain damage. It was found that the ability to control BCI did not depend on the duration of a disease, brain lesion localization and the degree of neurological deficit. The first step of the study involved 36 patients; it showed that the efficacy of rehabilitation was higher in the group with the use of BCI (the score on the Action Research Arm Test (ARAT) improved from 1 [0; 2] to 5 [0; 16] points, p = 0.012; no significant improvement was observed in control group). The second step of the study involved 19 patients; the complex BCI-exoskeleton (i.e. with the kinesthetic feedback) was used for motor imagery trainings. The improvement of the motor function of hands was proved by ARAT (the score improved from 2 [0; 37] to 4 [1; 45:5] points, p = 0.005) and Fugl-Meyer scale (from 72 [63; 110 ] to 79 [68; 115] points, p = 0.005).

    Full Text Available Raffaele De CaterinaInstitute of Cardiology and Center of Excellence on Aging, G d’Annunzio University, Chieti, G Monasterio Foundation, Pisa, ItalyAbstract: Atrial fibrillation is an extremely common arrhythmia, which substantially increases the risk of stroke and thromboembolism. Prevention of stroke and thromboembolism is therefore an important part of the management of atrial fibrillation. Guidelines until now have recommended that patients with atrial fibrillation receive some form of antithrombotic therapy, ie, a vitamin K antagonist or aspirin, with a preference for anticoagulants in most cases. However, current treatments are suboptimal, and despite the recommendations, many patients do not receive adequate thromboprophylaxis, because they are considered, for various reasons, “unsuitable” to receive a vitamin K antagonist. In this patient population, apixaban, a new oral anticoagulant inhibiting activated coagulation factor X, administered in fixed doses and without anticoagulation monitoring, has undergone testing against aspirin in the recently published AVERROES trial. This paper addresses the strengths and limitations of this trial and the practical relevance of the new clinical information it provides.Keywords: atrial fibrillation, apixaban, thromboprophylaxis

    Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy. PMID:16716846

    Cystic fibrosis-related diabetes (CFRD) patients suffer from accelerated rates of pulmonary decline compared to cystic fibrosis (CF) patients with normal glucose tolerance (NGT). However, the mechanisms underlying this difference are unknown. While CFRD is associated with increased respiratory infections, a link between infection and enhanced pulmonary dysfunction remains unclear. The development of glucose intolerance is spectral, resulting in impaired glucose tolerance (IGT) prior to the diagnosis of CFRD. Inclusion of IGT patients within the NGT group may diminish the ability to identify correlations with CFRD. With this in mind, this study aimed to determine if the association between CFRD and respiratory infections is correlated with pulmonary decline. Respiratory cultures from 234 CF patients with confirmed diagnosis of NGT or CFRD were analyzed to measure rates of infection, focusing on the two most prevalent bacteria in CF, Staphylococcus aureus and Pseudomonas aeruginosa. Infection status was correlated with pulmonary function and confounding clinical variables including age, gender, blood glucose levels, and CF transmembrane conductance regulator (CFTR) phenotype were considered in multivariate analyses. CFRD patients, particularly those with extremely high blood glucose levels, were more likely than NGT patients to be co-infected with S. aureus and P. aeruginosa, compared to infection with only one pathogen. Co-infection was associated with decreased lung function and increased frequency of pulmonary exacerbations, even after adjustment for confounding variables. Alterations in the microbial community composition, as opposed to the presence of a single pathogen, may account for greater pulmonary decline in CFRD patients. PMID:26993289

    Full Text Available Background/Aim: Clostridium difficile infection (CDI can affect up to 8% of hospitalized patients. Twenty-five percent CDI patients may develop C. difficile associated diarrhea (CDAD and 1-3% may progress to fulminant C. difficile colitis (FCDC. Once developed, FCDC has higher rates of complications and mortality. Patients and Methods: A 10-year retrospective review of FCDC patients who underwent colectomy was performed and compared with randomly selected age- and sex-matched non-fulminant CDAD patients at our institution. FCDC (n=18 and CDAD (n=49 groups were defined clinically, radiologically, and pathologically. Univariate analysis was performed using Chi-square and Student′s t test followed by multivariate logistic regression to compute independent predictors. Results: FCDC patients were significantly older (77 ± 13 years, presented with triad of abdominal pain (89%, diarrhea (72%, and distention (39%; 28% had prior CDI and had greater hemodynamic instability. In contrast, CDAD patients were comparatively younger (65 ± 20 years, presented with only 1 or 2 of these 3 symptoms and only 5% had prior CDI. No significant difference was noted between the 2 groups in terms of comorbid conditions, use of antibiotics, or proton pump inhibitor. Leukocytosis was significantly higher in FCDC patients (18.6 ± 15.8/mm 3 vs 10.7 ± 5.2/mm 3 ; P=0.04 and further increased until the point of surgery. Use of antiperistaltic medications was higher in FCDC than CDAD group (56% vs 22%; P=0.01. Conclusions: Our data suggest several clinical and laboratory features in CDI patients, which may be indicative of FCDC. These include old age (>70 years, prior CDI, clinical triad of increasing abdominal pain, distention and diarrhea, profound leukocytosis (>18,000/mm 3 , hemodynamic instability, and use of antiperistaltic medications.

    In order to evaluate the efficacy and safety of pivmecillinam (melysin tablet, PMPC), PMPC was administered to 78 chronic UTI cases in the field of obstetrics and gynecology (posthysterectomy infection, chronic cystitis, chronic pyelonephritis and etc.). In principle, daily 400 mg of PMPC was administered for 2 weeks. (1) Overall clinical efficacy judged by doctor was evaluated in 78 cases and the result was; excellent in 17, good in 37, fair in 10, poor in 13 and unknown in 1 case with the effectiveness rate of 69.2%. (2) Overall clinical efficacy judged by 'criteria for clinical evaluation in complicated UTI' recommended by UTI study member was evaluated in 54 cases and the result was; excellent in 15, good in 20 and poor in 19 cases with the overall efficacy rate of 64.8%, the result of which was similar to that of doctor's judgement. (3) Efficacy on pyuria was evaluated in 72 cases and it was cleared in 27, decreased in 25, unchanged in 20 and unknown in 6 cases. Efficacy on bacteriuria was evaluated in 72 cases and it was eliminated in 44, decreased in 9, replaced in 8, unchanged in 8 and unknown in 9 cases. (4) Side effect, considered by doctors to be caused by PMPC administration, was noticed in 3 out of 78 cases (3.8%), all of which was mild gastrointestinal disturbance and the administration of PMPC was continued. Abnormal change of laboratory finding considered by doctors to be caused by PMPC administration was noticed in 1 out of 78 cases, which was slight elevation of GOT and GPT values. It is therefore considered that PMPC appear to be useful drug for the maintenance therapy of chronic UTI in the field of obstetrics and gynecology. PMID:6276586

    Background Concurrent infection with multiple pathogens is common in tropics, posing diagnostic and treatment challenges. Although co-infections of dengue, malaria, leptospirosis and typhoid in various combinations have been described, data on dengue and scrub typhus co-infection is distinctly limited. Methodology This study was a retrospective analysis of dengue and scrub typhus co-infection diagnosed between January 2010 and July 2014 at a tertiary care center. Clinical and laboratory features of these cases were compared with age and gender-matched patients with isolated dengue fever and isolated scrub typhus. Positive test for dengue non-structural 1 (NS1) antigen was considered diagnostic of dengue whereas scrub typhus was diagnosed by IgM scrub antibodies demonstrated by ELISA. Results There were 6 cases of dengue-scrub co-infection during the review period which fitted clinical and laboratory profile with a mean age of 42.5 years. Fever, headache, and arthralgia were common. Normal hemoglobin, significant thrombocytopenia, transaminitis, and hypoalbuminemia were identified in these patients. Compared to patients with isolated dengue, those with co-infection had higher pulse rate, lower systolic blood pressure, normal leucocyte counts, higher levels of liver enzymes, greater prolongation of partial thromboplastin time (aPTT) and lower serum albumin. Co-infection was characterized by a lower nadir platelet count compared to scrub typhus, and lesser time to nadir platelet count and longer duration of hospital stay compared to either isolated dengue or scrub typhus. Conclusion Dengue-scrub typhus co-infection may be under-diagnosed in tropics, particularly confounded during dengue epidemics. Normal leukocyte counts, early drop in platelets and hypoalbuminemia in dengue patients could be clues to concurrent scrub typhus infection. Prompt recognition and treatment of scrub typhus in such cases may reduce unnecessary hospital stay and cost. PMID:27413521

  2. Clinical trial experience using erythropoietin during radiation therapy

    International Nuclear Information System (INIS)

    Oncologists have several reasons for trying to maintain or increase hemoglobin levels in their patients during therapy. Relief of the symptoms of anemia, including fatigue and dyspnea, are traditional, well-accepted indications. A newer rationale is to enhance the efficacy of radiation therapy and/or chemotherapy in controlling tumors. A laboratory animal study found that administration of recombinant human erythropoietin (rHuEPO) increased intratumoral median oxygen levels and diminished the proportion of measurements in the very low (<3 mm Hg) range. Hemoglobin level is a strong independent prognostic factor for tumor control by radiation therapy. The hemoglobin level at the end of radiation therapy is a stronger prognostic factor than is the hemoglobin level at the start of therapy. Numerous clinical trials have utilized rHuEPO during radiation with or without concurrent chemotherapy. All 4 trials which enrolled patients with low hemoglobin levels (<12 to 13.5 g/dl) found that rHuEPO significantly increased hemoglobin within 2 weeks and that hemoglobin levels continued to rise until the end of rHuEPO treatment. rHuEPO was efficacious in limiting the decrease in hemoglobin and use of packed red blood cell transfusion in the one reported trial in which it was used in patients with initially normal hemoglobin levels during intensive concurrent radiation and chemotherapy. One trial found a statistically significant improvement in complete pathologic response rate after neoadjuvant chemoradiotherapy with the use of rHuEPO. rHuEPO has a potentially large role to play in the care of the cancer patient.

    Full Text Available Introduction. Burns are an important public health challenge due to the frequency of getting burns in day-to-day life, occupational hazards, and catastrophes. Treatment of burns is complex and is associated with high morbidity and mortality. Duration and complexity of burn treatment require finding new ways of curing and rehabilitating burns. The result of burn treatment plays a significant role in post-traumatic status of a patient and his or her consequent adaptation in society. Chitosan is a natural safe non-toxic product compatible with human tissues, characterized by hydrosorbid, anticoagulant, antibacterial, and wound healing features. The study aims to  show a clinical application of chitosan-pectin scaffold with cultured human skin fibroblasts in the treatment of deep burns.Methods. The substrate was prepared by dissolving 3% chitosan in 0.5N acetic acid, which was then mixed with 3% solution of pectin dissolved in distillated water. Chitosan film was formed in a Petri dish for 20-24 hours at 20-25 °C. After drying the film, cultured allogeneic fibroblasts (patent number RK-25091 were seeded on its surface.Results. The results from an in vitro culture study showed that human allogeneic fibroblasts could adhere well and grow on the selected scaffold with a typical morphology. During autodermoplasty surgery, cultured allogeneic fibroblasts were applied on granulating wounds of 9 patients with IIIA to IVB degree burns and limited donor resources. Wounds treated with the fibroblast-seeded scaffold among all patients provided the highest level of re-epithelialization (day 5, in comparison to cell-free scaffold (day 7 and untreated surface of wounds (day 10.Conclusion. Our results indicate the potential use of chitosan for wound healing due to its allogenic fibroblast adherence to scaffolding as well as high epithelization. This warrants further studies on chitosan for use in wounds resulting from third and fourth degree burns.

    Background The controversy on the treatment strategy for severe acute pancreatitis (SAP) has never stopped for the past century.Even now surgical procedures play a decisive role in the treatment of SAP,especially in managing the related complications,but the rational indications,timing,and approaches of surgical intervention for SAP are still inconclusive.Methods Clinical data of 308 SAP patients recruited during January 2000-January 2013,including 96 conservatively treated cases plus 212 surgically intervened cases,were comparatively analyzed.Based on the initial surgical intervention time,the surgical intervention group was split into two:early intervention group (within 2 weeks) 103 cases,and late intervention group (after 2 weeks) 109 cases.Results In the conservative treatment group,the cure rate was 82.29% (79/96),the death rate was 13.54% (13/96),and 4 cases self-discharged,while in the surgical intervention group,the cure rate was 84.43% (179/212) and the death rate was 10.85% (23/212) with 10 cases self-discharged.The difference was of no statistical significance between these two groups (P >0.05).In surgical intervention group,the death rate 15.53% (16/103) in the early surgical intervention group was higher than that of late surgical intervention group 6.42% (7/109),and the difference was statistically significant (P <0.05).Conclusions Both conservative treatment and surgical intervention play important roles in the treatment of SAP,and the indication,timing,and procedure should be strictly followed.Surgery earlier than 2 weeks after onset of the disease is not recommended in patients with necrotizing pancreatitis only when there are specific indications,such as multiple organ failure,which does not improve despite active treatment,and in those who develop abdominal compartment syndrome.

Conclusion: Previous pelvic surgeries were the major etiological factor for EP. Other factors were infertility treatment and pelvic inflammatory disease. The most common site of EP was fallopian tubes.

  6. Respiratory dynamic CT of the lung: initial clinical experience

    International Nuclear Information System (INIS)

    We applied spiral CT to evaluate the dynamic changes of regional ventilation of the lung in normal subjects and abnormal patients. This study includes normal subjects (n = 5) and patients with chronic obstructive pulmonary disease (n = 4), small air-way disease (n = 3), diffuse panbronchiolitis (n = 4), and tracheobronchial tuberculosis (n = 2). Time-continuous scan data at a fixed level during forced vital capacity maneuver (10-12 seconds) were obtained and images were reconstructed retrospectively by using 0.67 second scan data per image. The reconstructed images were displayed in a cine mode. Time-density curves were plotted and were correlated with clinical diagnosis. In normal subjects, mean attenuation difference between full inspiration and full expiration was 145.8 HU and mean time interval between 20% expiration and 80% expiration was 2.04 seconds. In chronic obstructive lung disease, mean attenuation difference between full inspiration and full expiration was 21.2 HU and mean time interval between 20% expiration and 80% expiration was 3.63 seconds. In small air-way disease, mosaic-pattern hyperlucency and normal portion of lung showed mean attenuation differences between 20% expiration and 80% expiration to be 49.8 HU and 167.0 HU, respectively. In diffuse panbronchiolitis, centrilobular region and normal portion of lung showed mean attenuation differences between 20% expiration and 80% expiration to be 35.4 HU and 79.3 HU, respectively. Respiratory dynamic CT is an updated technique which enable imaging of the functional status of the lung parenchyma. It may be useful in differentiation and quantitation of variable obstructive lung diseases

  7. Clinical experiences with three different designs of ankle prostheses.

    Until 1995, fusion was in our institution the only rational surgical option for a severe ankle arthrosis. Consistent reports about good mid- and long-term results with ankle replacement allowed us to change our minds. Ankle replacement became the gold standard and fusion was then almost totally banished. Because ankle arthrosis can be morphologically different from one patient to another, we soon believed that one single type of ankle prosthesis would not be the universal optimal solution for all patients. We therefore divided the ankle arthrosis into three groups. Each group shows the best solution from each of the ankle prostheses with which we had gained experience (Agility, STAR, and BP). The Agility prosthesis, which was indicated for ankles with extremely damaged geometry, did not restore sufficiently the ankle motion. Preoperatively stiff ankles remained stiff postoperatively. Additionally, significant residual pain was more likely to occur in those patients. These cases did not show significant advantages compared with ankle fusion, especially from a functional point of view. Fusion for these stiff ankles is therefore today our first treatment of choice. In our experience, the malleolar joints do not have to be replaced. Even a severe arthrosis at this level does not produce significant pain, provided that osteophytes have been removed and joint height has been restored by the implanted prosthesis. It is our strong belief that these malleolar joints are also less sensitive to pain, similar to the femoropatellar joint. For these reasons, a replacement of the malleolar joints and the resurfacing of the talar sides is not necessary. Leaving the talar sides untouched requires less bone resection and makes the implantation of the talar component easier. Although we obtained good results with the STAR prosthesis, we progressively abandoned it because of these reasons, and we preferred the BP prosthesis. The BP prosthesis works on the same biomechanic principle as

    2015-02-01

    Full Text Available Background: The clinical learning environment is a complex social entity that influences student learning outcomes in the clinical setting. Students can experience the clinical learning environment as being both facilitative and obstructive to their learning. The clinical environment may be a source of stress, creating feelings of fear and anxiety which in turn affect the students’ responses to learning. Equally, the environment can enhance learning if experienced positively.Objectives: This study described pupil enrolled nurses’ experiences of facilitative and obstructive factors in military and public health clinical learning settings.Method: Using a qualitative, contextual, exploratory descriptive design, three focus group interviews were conducted until data saturation was reached amongst pupil enrolled nurses in a military School of Nursing.Results: Data analysed provided evidence that acceptance by clinical staff and affordance of self-directed learning facilitated learning. Students felt safe to practise when they were supported by the clinical staff. They felt a sense of belonging when the staff showed an interest in and welcomed them. Learning was obstructed when students were met with condescending comments. Wearing of a military uniform in the public hospital and horizontal violence obstructed learning in the clinical learning environment.Conclusion: Students cannot have effective clinical preparation if the environment is not conducive to and supportive of clinical learning, The study shows that military nursing students experience unique challenges as they are trained in two professions that are hierarchical in nature. The students experienced both facilitating and obstructing factors to their learning during their clinical practice. Clinical staff should be made aware of factors which can impact on students’ learning. Policies need to be developed for supporting students in the clinical learning environment.

    Full Text Available Background: Autologous Bone Marrow stem Cell transplantation is a viable therapeutic option for patients with end stage heart failure due to cardiomyopathy of varied etiology as there are only limited treatment options other than cardiac transplantation. The rationale behind the application of stem cells in these patients include • Stem cells directly replace the affected cells by differentiation into the damaged cell type • Stem cells also exert Paracrine effects by secre tion of growth factors (VGEF,FGF-1to stimu late local cell growth•In addition to the above, stem cells release signaling factors which recruit stem cells from elsewhere by modulating the immune system.Materials and Methods: In this presentation we describe our study on a series of 13 patients who received isolated and expanded CD 34 cells from the bone marrow. Seven had ischemic dysfunction, three had dilated cardiomyopathy and three had primary pulmonary hypertension. Five patients received the stem cells via intracoronary injection, three directly into the myocardium and three intrapulmonary. Results: All patients showed functional improvement of the myocardium recorded by non-invasive investigations and improvement in the quality of life. Follow up period ranged from 6 months to 2 years. Conclusion: Our experience with bone marrow derived stem cells in patients with cardiomyopathy has been encouraging. More studies are planned in the future.

    Twenty-five barrier-maintained cats had been experimentally infected for 9.5 months with an FIV strain of low pathogenicity, FIV Zurich 2. Animals were clinically healthy and did not exhibit any haematological changes. FIV proviral DNA was demonstrated in peripheral blood lymphocytes of all cats and in monocytes of most animals, identifying FIV Zurich 2 as a both lympho- and monocytotropic strain. Monocytes were isolated from FIV-infected cats as well as from age-matched uninfected control cats, short-term cultured and examined for cytokine (IL-1beta, IL-6, IL-10, IL-12 p40 and TNF-alpha) transcription by real-time PCR. Constitutive transcription of cytokines in monocytes from FIV-infected cats was restricted to IL-1beta and, in the majority of samples, TNF-alpha. For all cytokines, transcription levels were significantly lower in FIV-infected cats than in control cats. Transcription was often least intense in those samples where FIV infection of the monocyte fraction was not demonstrated. Results show that infection of cats with an FIV strain of low pathogenicity was associated with depression of constitutive cytokine transcription in monocytes even if clinical and haematological changes were not observed.

    Stubbs, P

    1998-11-01

    Recent advances in pharmacological and mechanical approaches to acute coronary syndromes have led to rapid changes in the management of patients admitted with acute coronary syndromes. These changes have been mirrored by the appearance of newer highly specific biochemical markers of myocardial damage particularly the cardiac troponins. When new biochemical markers become available it is the responsibility of the clinical chemist to evaluate them critically in terms of sensitivity, specificity, efficiency and analyzer precision, in the rigid setting of quality control that laboratories practise, and to compare them with other markers. When the data are shown to Clinical Cardiologists with supporting statements such as 'useful management tool' and 'can be used for early diagnosis of Myocardial Infarction', a different set of questions may need to be answered. The 'So what?' response is most frequent and is the most important hurdle that these newer biochemical markers have to overcome to convince physicians to change their current practice. This presentation will review the results of studies that have examined the potential clinical usefulness of the cardiac troponins with respect to diagnosis and risk stratification of patients admitted with suspected acute coronary syndromes. Any troponin variable that survives the 'so what' question has one further major hurdle to overcome. This is the requirement to inform physicians what different therapeutic strategies they should follow if the variable is present. Available clinical trial evidence about differing management options for patients according to their troponin status will be reviewed and outline management algorithms will be presented. Many questions remain unanswered and these will be included at the time points where they may be relevant. PMID:9857942
