In systemic sclerosis (SSc), a specific nailfold videocapillaroscopy (NVC) pattern is observed in 90% of cases and seems to be associated with severity and progression of the disease. To describe the characteristics of SSc patients with normal or nonspecific (normal/nonspecific) NVC. In a retrospective cohort study, clinical features and visceral involvements of 25 SSc cases with normal/nonspecific NVC were compared to 63 SSc controls with the SSc-specific NVC pattern. Normal/nonspecific NVC versus SSc-specific NVC pattern was significantly associated with absence of skin sclerosis (32 vs. 6.3%, p = 0.004), absence of telangiectasia (47.8 vs. 17.3%, p = 0.006) and absence of sclerodactyly (60 vs. 25.4%, p = 0.002), and less frequent severe pulmonary involvement (26.3 vs. 58.2%, p = 0.017). Normal/nonspecific NVC in SSc patients appears to be associated with less severe skin involvement and less frequent severe pulmonary involvement. © 2014 S. Karger AG, Basel.

Previous epidemiological studies have highlighted the high risk of injury to the head, thorax, and cervical spine in rollover crashes. However, such results provide limited information on whole-body injury distribution and multiple region injury patterns necessary for the improvement and prioritization of rollover-focused injury countermeasures. Sampled cases representing approximately 133,000 U.S. adult occupants involved in rollover crashes (between 1995 and 2013) sustaining moderate-to-severe injuries were selected from the National Automotive Sampling System Crashworthiness Data System database. A retrospective cohort study, based on a survey of population-based data, was used to identify relevant whole body injury patterns. Among belted occupants injured in rollover crashes, 79.2% sustained injuries to only one body region. The three most frequently injured (AIS2+) body regions were head (42.1%), upper extremity (28.0%), and thorax (27.1%). The most frequent multi-region injury pattern involved the head and upper extremity, but this pattern only accounted for 2.3% of all of occupants with moderate or worse injuries. The results indicated that for rollover-dominated crashes, the frequently observed injury patterns involved isolated body regions. In contrast, multi-region injury patterns are more frequently observed in rollovers with significant planar impacts. Identification of region-specific injury patterns in pure rollover crashes is essential for clarifying injury mitigation targets and developing whole-body injury metrics specifically applicable to rollovers.

To perform a systematic review of neurologic involvement in Systemic sclerosis (SSc) and Localized Scleroderma (LS), describing clinical features, neuroimaging, and treatment. We performed a literature search in PubMed using the following MeSH terms, scleroderma, systemic sclerosis, localized scleroderma, localized scleroderma "en coup de sabre", Parry-Romberg syndrome, cognitive impairment, memory, seizures, epilepsy, headache, depression, anxiety, mood disorders, Center for Epidemiologic Studies Depression (CES-D), SF-36, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Patient Health Questionnaire-9 (PHQ-9), neuropsychiatric, psychosis, neurologic involvement, neuropathy, peripheral nerves, cranial nerves, carpal tunnel syndrome, ulnar entrapment, tarsal tunnel syndrome, mononeuropathy, polyneuropathy, radiculopathy, myelopathy, autonomic nervous system, nervous system, electroencephalography (EEG), electromyography (EMG), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). Patients with other connective tissue disease knowingly responsible for nervous system involvement were excluded from the analyses. A total of 182 case reports/studies addressing SSc and 50 referring to LS were identified. SSc patients totalized 9506, while data on 224 LS patients were available. In LS, seizures (41.58%) and headache (18.81%) predominated. Nonetheless, descriptions of varied cranial nerve involvement and hemiparesis were made. Central nervous system involvement in SSc was characterized by headache (23.73%), seizures (13.56%) and cognitive impairment (8.47%). Depression and anxiety were frequently observed (73.15% and 23.95%, respectively). Myopathy (51.8%), trigeminal neuropathy (16.52%), peripheral sensorimotor polyneuropathy (14.25%), and carpal tunnel syndrome (6.56%) were the most frequent peripheral nervous system involvement in SSc. Autonomic neuropathy involving cardiovascular and gastrointestinal systems was regularly described. Treatment of nervous system involvement, on the other hand, varied in a case-to-case basis. However, corticosteroids and cyclophosphamide were usually prescribed in severe cases. Previously considered a rare event, nervous system involvement in scleroderma has been increasingly recognized. Seizures and headache are the most reported features in LS en coup de sabre, while peripheral and autonomic nervous systems involvement predominate in SSc. Moreover, recently, reports have frequently documented white matter lesions in asymptomatic SSc patients, suggesting smaller branches and perforating arteries involvement.

2017-04-01

A growing body of research suggests that people who are more deeply involved in religion may be more likely to adopt beneficial health behaviors. However, religion is a complex phenomenon, and as a result, religion may affect health behaviors in a number of ways. The purpose of the current study was to see whether a sacred view of the body (i.e., belief that the body is the temple of God) is associated with better health behavior. It was proposed that the relationship between a sacred body view and health behavior will emerge only among study participants who have a stronger sense of religiously oriented control (i.e., stronger God-mediated control beliefs). Five positive health behaviors were evaluated: more frequent strenuous exercise, more frequent moderate exercise, more frequent consumption of fruits and vegetables, higher quality sleep, and the adoption of healthy lifestyles. Data from a recent nationwide sample reveal that a sacred body view is associated with each health behavior, but only among study participants who have a strong religiously oriented sense of control.

Research investigating frequent sickness absence (3 or more episodes per year) is scarce and qualitative research from the perspective of frequent absentees themselves is lacking. The aim of the current study is to explore awareness, determinants of and solutions to frequent sickness absence from the perspective of frequent absentees themselves. We performed a qualitative study of 3 focus group discussions involving a total of 15 frequent absentees. Focus group discussions were audiotaped and transcribed verbatim. Results were analyzed with the Graneheim method using the Job Demands Resources (JD-R) model as theoretical framework. Many participants were not aware of their frequent sickness absence and the risk of future long-term sickness absence. As determinants, participants mentioned job demands, job resources, home demands, poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Managing these factors and improving communication (skills) were regarded as solutions to reduce frequent sickness absence. The JD-R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

Life-sustaining treatment decisions in Portuguese intensive care units: a national survey of intensive care physicians.

Cardoso, Teresa; Fonseca, Teresa; Pereira, Sofia; Lencastre, Luís

2003-12-01

The objective of the present study was to evaluate the opinion of Portuguese intensive care physicians regarding 'do-not-resuscitate' (DNR) orders and decisions to withhold/withdraw treatment. A questionnaire was sent to all physicians working on a full-time basis in all intensive care units (ICUs) registered with the Portuguese Intensive Care Society. A total of 266 questionnaires were sent and 175 (66%) were returned. Physicians from 79% of the ICUs participated. All participants stated that DNR orders are applied in their units, and 98.3% stated that decisions to withhold treatment and 95.4% stated that decisions to withdraw treatment are also applied. About three quarters indicated that only the medical group makes these decisions. Fewer than 15% of the responders stated that they involve nurses, 9% involve patients and fewer than 11% involve patients' relatives in end-of-life decisions. Physicians with more than 10 years of clinical experience more frequently indicated that they involve nurses in these decisions (P < 0.05), and agnostic/atheist doctors more frequently involve patients' relatives in decisions to withhold/withdraw treatment (P < 0.05). When asked about who they thought should be involved, more than 26% indicated nurses, more than 35% indicated the patient and more than 25% indicated patients' relatives. More experienced doctors more frequently felt that nurses should be involved (P < 0.05), and male doctors more frequently stated that patients' relatives should be involved in DNR orders (P < 0.05). When a decision to withdraw treatment is made, 76.8% of 151 respondents indicated that they would initiate palliative care; no respondent indicated that they would administer drugs to accelerate the expected outcome. The probability of survival from the acute episode and patients' wishes were the most important criteria influencing end-of-life decisions. These decisions are made only by the medical group in most of the responding ICUs, with little input from nursing staff, patients, or patients' relatives, although many respondents expressed a wish to involve them more in this process. Sex, experience and religious beliefs of the respondents influences the way in which these decisions are made.

2015-04-01

The purpose of the study is to evaluate the impact of primary service involvement on rapid response team (RRT) evaluations. The study is a combination of retrospective chart review and prospective survey-based evaluation. Data included when and where the activations occurred and the patient's code status, primary service, and ultimate disposition. These data were correlated with survey data from each event. A prospective survey evaluated the primary team's involvement in decision making and the overall subjective quality of the interaction with primary service through a visual analog scale. We analyzed 4408 RRTs retrospectively and an additional 135 prospectively. The primary team's involvement by telephone or in person was associated with significantly more transfers to higher care levels in retrospective (P < .01) and prospective data sets. Code status was addressed more frequently in primary team involvement, with more frequent changes seen in the retrospective analysis (P = .01). Subjective ratings of communication by the RRT leader were significantly higher when the primary service was involved (P < .001). Active primary team involvement influences RRT activation processes of care. The RRT role should be an adjunct to, but not a substitute for, an engaged and present primary care team.

The purpose of our study is to review our 15-year experience with pediatric patients who have been diagnosed with neuroblastoma, and to determine their most frequent head and neck manifestations and symptoms. Retrospective chart review of electronic medical record. An academic, tertiary care pediatric hospital. IRB approval from the Office of Research Integrity at Children's Mercy Hospital was obtained. The hospital tumor database was analyzed to identify patients with neuroblastoma, ganglioneuroblastoma, and esthesioneuroblastoma diagnosed between 1997 and 2012. We recorded the various clinical signs and symptoms these patients displayed at their initial presentation, focusing on patients with head and neck involvement. We then determined the relative incidence of these various findings. Our review yielded 118 patients diagnosed with neuroblastoma, ganglioneuroblastoma, or esthesioneuroblastoma over our 15 year study period. 7 of the 118 patients were diagnosed with primary tumors of the head and neck. Another 19 patients had metastatic head and neck involvement. For those with primary disease, presence of a neck mass and signs of Horner's syndrome were the most common findings. For metastatic disease, craniofacial bony metastasis was the most frequent finding in our study. Based on our data, there are a handful of findings that occur frequently in pediatric head and neck neuroblastoma. Any persistent neck mass, unexplained Horner's syndrome, or periorbital ecchymosis should be carefully evaluated. This study should serve as an aid for the otolaryngologist to be aware of the possible manifestations of this malignancy in children. Copyright © 2017 Elsevier B.V. All rights reserved.

Pulmonary manifestations in systemic lupus erythematosus: pleural involvement, acute pneumonitis, chronic interstitial lung disease and diffuse alveolar hemorrhage.

PubMed

Aguilera-Pickens, Georgina; Abud-Mendoza, Carlos

2018-05-14

Systemic lupus erythematosus is the diffuse autoimmune connective tissue disease that most frequently involves pulmonary involvement, affecting 20% of 90% of the patients. The percentage varies depending on the defining criteria (symptoms, pulmonary tests or histopathological studies). At least once during the disease course, 50% of those affected have pleural and/or pulmonary manifestations, which are associated with higher morbidity and mortality. Pulmonary involvement has no correlation with lupus activity biomarkers, and it is necessary to rule out infectious processes in the initial approach. Bacterial infection is most frequently the cause of lung involvement in lupus and is one of the most important causes of death. Pulmonary involvement is considered to be primary when it is associated with disease activity, and secondary when other causes participate. Drugs have been reported to be associated with pulmonary damage, including interstitial disease. The incidence of malignant lung diseases is increased in systemic lupus erythematosus. Treatment depends on the type and severity of pulmonary involvement. Copyright © 2018 Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. Publicado por Elsevier España, S.L.U.

2010-01-01

Purpose The study compared levels of depression among bullies, victims and bully-victims of traditional (physical, verbal and relational) and cyber bullying, and examined the association between depression and frequency of involvement in each form of bullying. Methods A U.S. nationally-representative sample of students in grades 6 to 10 (N = 7313) completed the bullying and depression items in the Health Behavior in School-Aged Children (HBSC) 2005 Survey. Results Depression was associated with each of four forms of bullying. Cyber victims reported higher depression than bullies or bully-victims, a finding not observed in other forms of bullying. For physical, verbal and relational bullies, victims and bully victims, the frequently-involved group reported significantly higher level of depression than the corresponding occasionally-involved group. For cyber bullying, differences were found only between occasional and frequent victims. Conclusion Findings indicate the importance of further study of cyber bullying as its association with depression is distinct from traditional forms of bullying. PMID:21402273

Evaluating the direction of effects in the relationship between religious versus non-religious activities, academic success, and substance use.

PubMed

Good, Marie; Willoughby, Teena

2011-06-01

This longitudinal study tested the influence of involvement and selection hypotheses for the association between religious versus non-religious activity involvement and two salient indicators of adolescent psychosocial adjustment (substance use and academic achievement). Participants included 3,993 Canadian adolescents (49.4% girls) who were surveyed each year from grades 9-12. More frequent religious attendance (but not non-religious club involvement) in one grade predicted lower levels of substance use in the next grade. Higher levels of non-religious club involvement (but not religious service attendance) in one grade predicted higher academic achievement in the next grade, and higher academic achievement in one grade predicted more frequent non-religious club involvement in the next grade. The effects were robust, as they were invariant across grade and significant after controlling for individual, peer, and family characteristics. Most importantly, these results suggest that religious activities are not just another club, but, rather, that different developmental assets may be fostered in religious as compared to non-religious activities.

2010-10-01

The pathophysiology of Sturge-Weber syndrome is poorly understood, and ear, nose, and throat involvement is possible. These issues can result in frequent illnesses or airway obstruction, affecting patients' neurologic status. Patients with definite brain involvement who reported potential ear, nose, and throat issues on intake questionnaires underwent retrospective reviews of their medical records. We examined the relationships between these issues, secondary surgical interventions, and patients' neurologic status. The most common complaints involved the sinuses and frequent ear infections. Six patients underwent placement of ear tubes, leading to improvements in migraines and stroke-like episodes in one patient, and improved seizure control in four others. Obstructive sleep apnea was confirmed in three patients who underwent sleep studies. Tonsil or adenoid removal occurred in another three patients. Surgery resulted in marked improvements regarding excessive drooling, daytime sleepiness, and breathing problems. These findings suggest that ear, nose, and throat problems occur frequently in patients with Sturge-Weber Syndrome, and when repeated ear infections are associated with uncontrolled seizures, early placement of ear tubes may be beneficial. Furthermore, patients with facial tissue hypertrophy may be at risk for obstructive sleep apnea, and should be appropriately evaluated. Copyright © 2010 Elsevier Inc. All rights reserved.

[The role of family carers of people with dementia in the assessment of need on the example of the CarenapD study].

Riesner, Christine

2014-08-01

Need driven dementia care at home requires the use of needs assessments like CarenapD. The CarenapD Manual states that the person with dementia (PwD) and caregivers (CA) should be included in the assessment process. In a pre-post study CarenapD has been applied in PwD (n = 55) and CA (n = 49) by professional staff (n = 15), CA were much more involved than PwD. Needs in PwD in T0 and T1 showed frequently functional needs(50 %), no need were frequently found in dementia-specific needs (42 %) and frequently unmet need was present in social needs (35 %). Burden-related needs in CA were reduced from T0 to T1 in daily difficulties (-14 %), support (-20 %) and breaks from caring (-9 %).This secondary analysis compares the need results of PwD and CA to discuss the unequal involvement of clients. In this secondary analysis needs data of PwD and CA is included. Need in PwD at T0 and T1 showed frequently met functional need (50 %), frequently no need in dementia specific needs (42 %) and high unmet need in social needs (35 %). Burden in CA could be reduced from T0 to T1 in Daily Difficulties (-14 %), Support (-20 %) and Breaks from Caring (9 %). Compared to the literature it is remarkable that a high rate in no need was found in dementia specific needs. Needs of CA show congruent results, it seems to have come to relief of burden in CA. Lack of knowledge and shame in CA as well as the continuous presence of both clients within the assessment process may have caused that dementia-specific needs were not enough addressed. PwD and CA should be actively involved in the assessment process and should contribute their individual point of view, as stated in the CarenapD Manual.

Blastic plasmacytoid dendritic cell neoplasm frequently shows occult central nervous system involvement at diagnosis and benefits from intrathecal therapy.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive myeloid neoplasm which shows a high rate of central nervous system (CNS) recurrence and overall survival (OS) of <1 year. Despite this, screening for CNS involvement is not routinely performed at diagnosis and intrathecal (IT) prophylaxis is not regularly administered in BPDCN. Here, we prospectively evaluated 13 consecutive BPDCN patients for the presence of CNS involvement by flow cytometry. Despite none of the patients presented with neurological symptoms, occult CNS involvement was detected in 6/10 cases evaluated at diagnosis and 3/3 studied at relapse/progression. BPDCN patients evaluated at diagnosis received IT treatment -either CNS prophylaxis (n = 4) or active therapy (n = 6)- and all but one remain alive (median follow-up of 20 months). In contrast, all three patients assessed at relapse/progression died. The potential benefit of IT treatment administered early at diagnosis on OS and CNS recurrence-free survival of BPDCN was further confirmed in a retrospective cohort of another 23 BPDCN patients. Our results show that BPDCN patients studied at diagnosis frequently display occult CNS involvement; moreover, they also indicate that treatment of occult CNS disease might lead to a dramatically improved outcome of BPDCN.

2002-01-01

Our recent genome-wide allelotyping analysis of gallbladder carcinoma identified 3p, 8p, 9q and 22q as chromosomal regions with frequent loss of heterozygosity. The present study was undertaken to more precisely identify the presence and location of regions of frequent allele loss involving those chromosomes in gallbladder carcinoma. Microdissected tissue from 24 gallbladder carcinoma were analysed for PCR-based loss of heterozygosity using 81 microsatellite markers spanning chromosome 3p (n=26), 8p (n=14), 9q (n=29) and 22q (n=12) regions. We also studied the role of those allele losses in gallbladder carcinoma pathogenesis by examining 45 microdissected normal and dysplastic gallbladder epithelia accompanying gallbladder carcinoma, using 17 microsatellite markers. Overall frequencies of loss of heterozygosity at 3p (100%), 8p (100%), 9q (88%), and 22q (92%) sites were very high in gallbladder carcinoma, and we identified 13 distinct regions undergoing frequent loss of heterozygosity in tumours. Allele losses were frequently detected in normal and dysplastic gallbladder epithelia. There was a progressive increase of the overall loss of heterozygosity frequency with increasing severity of histopathological changes. Allele losses were not random and followed a sequence. This study refines several distinct chromosome 3p, 8p, 9q and 22q regions undergoing frequent allele loss in gallbladder carcinoma that will aid in the positional identification of tumour suppressor genes involved in gallbladder carcinoma pathogenesis.

Are physical activity studies in Hispanics meeting reporting guidelines for continuous monitoring technology? A systematic review.

Continuous monitoring technologies such as accelerometers and pedometers are the gold standard for physical activity (PA) measurement. However, inconsistencies in use, analysis, and reporting limit the understanding of dose-response relationships involving PA and the ability to make comparisons across studies and population subgroups. These issues are particularly detrimental to the study of PA across different ethnicities with different PA habits. This systematic review examined the inclusion of published guidelines involving data collection, processing, and reporting among articles using accelerometers or pedometers in Hispanic or Latino populations. English (PubMed; EbscoHost) and Spanish (SCIELO; Biblioteca Virtual en Salud) articles published between 2000 and 2013 using accelerometers or pedometers to measure PA among Hispanics or Latinos were identified through systematic literature searches. Of the 253 abstracts which were initially reviewed, 57 met eligibility criteria (44 accelerometer, 13 pedometer). Articles were coded and reviewed to evaluate compliance with recommended guidelines (N = 20), and the percentage of accelerometer and pedometer articles following each guideline were computed and reported. On average, 57.1 % of accelerometer and 62.2 % of pedometer articles reported each recommended guideline for data collection. Device manufacturer and model were reported most frequently, and provision of instructions for device wear in Spanish was reported least frequently. On average, 29.6 % of accelerometer articles reported each guideline for data processing. Definitions of an acceptable day for inclusion in analyses were reported most frequently, and definitions of an acceptable hour for inclusion in analyses were reported least frequently. On average, 18.8 % of accelerometer and 85.7 % of pedometer articles included each guideline for data reporting. Accelerometer articles most frequently included average number of valid days and least frequently included percentage of wear time. Inclusion of standard collection and reporting procedures in studies using continuous monitoring devices in Hispanic or Latino population is generally low. Lack of reporting consistency in continuous monitoring studies limits researchers' ability to compare studies or draw meaningful conclusions concerning amounts, quality, and benefits of PA among Hispanic or Latino populations.

Systemic sclerosis and localized scleroderma in childhood.

PubMed

Zulian, Francesco

2008-02-01

Juvenile scleroderma syndromes, including the systemic and the localized varieties, represent the third most frequent chronic rheumatic conditions in pediatric rheumatology practice. In children, systemic sclerosis shows a significantly less frequent involvement of all organs, a higher prevalence of arthritis and myositis, and a better outcome than in adults. Recently, new classification criteria were proposed, which help improve patient care by enabling earlier, more definite diagnoses and by standardizing the conduct of clinical trials. Localized scleroderma is the more frequent subtype of scleroderma in childhood. It comprises a group of distinct conditions that involve mainly the skin and subcutaneous tissues. They range from small plaques of fibrosis involving only the skin to diseases causing significant functional deformity with various extracutaneous features.

To analyse the most recently published studies on the prevalence of allergic conjunctivitis alone or in association with allergic rhinitis, and the clinical and demographic aspects of the disease. Allergic conjunctivitis or conjunctival symptoms are present in 30-71% of patients with allergic rhinitis. Allergic conjunctivitis alone has been estimated in 6-30% of the general population and in up to 30% in children alone or in association with allergic rhinitis. Seasonal allergic conjunctivitis is the most frequent form; however, studies from tertiary, ophthalmology referral centers report that the chronic forms, such as vernal and atopic keratoconjunctivitis, are the most frequently seen by ophthalmologists. A recent large survey performed at a national level involving 304 ophthalmologists showed that the majority of patients with allergic conjunctivitis suffer annually of few episodes of mild ,intermittent conjunctivitis. However, 30% of patients are affected by frequent episodes with intense and persistent symptoms. Treatment is frequently not appropriate. Even though allergic conjunctivitis is often associated to allergic rhinitis, epidemiology studies frequently do not include specific ophthalmological evaluations. An understanding of allergic conjunctivitis disease, its prevalence, demographics and treatment paradigms will provide important information towards understanding its pharmacoeconomics and burden on the national health systems.

“A Twenty-Hour-a-Day Job”: The Impact of Frequent Low-Level Criminal Justice Involvement on Family Life

PubMed Central

Comfort, Megan

2017-01-01

In the growing field of research on the consequences of criminal justice contact for family life, a heavy emphasis has been placed on how imprisonment influences the emotional, physical, and socioeconomic wellbeing of prisoners’ loved ones. In this article, I elaborate on and analyze the experiences of family members of people with frequent, low-level criminal justice involvement. I draw on ethnographic data collected in partnership with a clinical social worker over the course of a three-year study of an intensive case management intervention for HIV-positive individuals. Findings indicate that loved ones’ brief jail stays and community supervision through probation and parole pose hardships for family members that are distinct from those hardships that arise during imprisonment. These experiences are uniquely destabilizing, may confer specific risks to family members’ wellbeing, and merit further study to inform programs, social services, and public policy. PMID:28935993

[Mining analysis on composition and medication of menstruation prescriptions in Fu Qingzhu's Obstetrics and Gynecology].

Zhu, Jia-qing; Che, Yu-xia

2015-04-01

In this paper, menstruation prescriptions were selected from "Fu Qingzhu's Obstetrics and Gynecology" and analyzed by using GRI algorithm, correlation analysis, hierarchical clustering method through SPSS, Clementine and traditional Chinese medicine (TCM) inheritance auxiliary systems, in order to screen out 15 menopathy prescriptions, which involve 45 traditional Chinese medicine herbs. In the study, blood-tonifying and qi-tonifying herbs were found to be frequent in the prescriptions. The most frequent single herb was white paeony root, accounting for 9.6% in the total number of prescriptions; The most frequent herb pairs were white paeony root-radix rehmanniae preparata and paeony root-angelica sinensis. Among Fu Shan's menopathy prescriptions, 61 herbal pairs showed a correlation coefficient exceeding 0.05, which evolved into 16 pairs of core combinations. The analysis showed that menopathy prescriptions in volume 1 of "Fu Qingzhu's Obstetrics and Gynecology" focused on tonic traditional Chinese medicines involving liver, spleen and kidney and were adjusted according to changes in qi, blood, cold, hot and wet, which could provide a specific reference for further studies on Fu Shan's academic thoughts and traditional Chinese medicine clinical treatment of menopathy.

A transsexual course of development that starts before puberty (early onset) or during or after puberty, respectively (late onset), may lead to diverse challenges in coping with sexual activity. The authors explored the sexual behavior of 380 adult male-to-female and female-to-male individuals diagnosed according to DSM-IV-TR criteria who had not yet undergone gender-confirming interventions. Data originated from the European Network for the Investigation of Gender Incongruence Initiative, conducted in Belgium, Germany, The Netherlands, and Norway. Information on outcome variables was collected using self-administered questionnaires at first clinical presentation. Compared with late-onset male-to-females, early-onset individuals tended to show sexual attraction toward males more frequently (50.5%), involve genitals less frequently in partner-related sexual activity, and consider penile sensations and orgasm as more negative. Early-onset female-to-males predominantly reported sexual attraction toward females (84.0%), whereas those with a late-onset more frequently showed other sexual attractions (41.7%). The study (a) shows that early- and late-onset male-to-females differ considerably with regard to coping strategies involving their body during sexual relations and (b) reveals initial insights into developmental pathways of late-onset female-to-males.

Comprehensive Strategies to Reduce Readmissions in Older Patients With Cardiovascular Disease.

PubMed

Dharmarajan, Kumar

2016-11-01

Older adults are frequently readmitted to the hospital soon after hospitalization for common cardiovascular conditions. Yet there are few high-quality data on the best strategies to reduce short-term readmissions because most studies have involved small numbers of participants, single-centre design, and strong susceptibility to bias. Despite these limitations in the literature, a clear signal exists that most studies involving a singular type of intervention, a singular type of health provider, or a low intensity of intervention have failed to reduce readmissions. In contrast, interventions that are most likely to lower readmissions have used comprehensive approaches, including combined hospital and postacute care, multimodal interventions, multidisciplinary teams, or frequent longitudinal contact. Components of a comprehensive approach with the highest level of evidence include high-quality, disease-specific care; multiple transitional care interventions; involvement of multidisciplinary teams; early and frequent outpatient follow-up; and, when possible, home visits. These findings are consistent with data demonstrating that older adults have multiple sources of vulnerability and experience elevated readmission risk from a broad spectrum of medical conditions for an extended time after hospital discharge. Because readmission reduction is difficult and requires new ways of conceptualizing links between inpatient and postacute care, financial incentives may ultimately be required to motivate hospitals and health systems to redesign care processes, deploy new resources, and collaborate with out-of-hospital providers and organizations.

Facial injuries frequently occur in traffic accidents involving motorcycles. The purpose of this study was to determine the prevalence of facial injuries among motorcycle drivers who perform motorcycle taxi service. The study design was cross-sectional. A total of 210 participants who served as motorcycle taxi drivers in a city in northeastern Brazil completed a survey concerning their experience of accidents involving facial injuries and consequent hospitalization and absenteeism from work. The motorcycle drivers included in the study were randomly selected from a list provided by the city. Out of the respondents, 165 (78.6%) who were involved in traffic accidents in the last 12 months, 15 (9.1%) reported facial injuries. The types of facial injury most frequently reported involved soft tissues (n = 8; 53.3%), followed by simple fracture (n = 4; 26.7%) and dentoalveolar fracture (n = 3; 20%). We found an association between facial injuries and absenteeism, as well as an association between the presence of facial injury and the need for hospitalization for a period of 2 days or more. Respondents reported that they had accidents, but due to the use of full face motorcycle helmet the number of facial injuries was low. For most of them, absenteeism was observed for a period of one month or more. Copyright © 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

2016-03-01

Distracted driving is a major cause of motor vehicle collision (MVC) involvement. Pets have been identified as potential distraction to drivers, particularly in the front. This type of distraction could be worse for those with impairment in the cognitive aspects of visual processing. The purpose of this study is to evaluate the association between driving with pets and rates of motor vehicle collision involvement in a cohort of older drivers. A three-year prospective study was conducted in a population-based sample of 2000 licensed drivers aged 70 years and older. At the baseline visit, a trained interviewer asked participants about pet ownership, whether they drive with pets, how frequently, and where the pet sits in the vehicle. Motor vehicle collision (MVC) involvement during the three-year study period was obtained from the Alabama Department of Public Safety. At-fault status was determined by the police officer who arrived on the scene. Participants were followed until the earliest of death, driving cessation, or end of the study period. Poisson regression was used to calculate crude and adjusted rate ratios (RR) examining the association between pet ownership, presence of a pet in a vehicle, frequency of driving with a pet, and location of the pet inside with vehicle with any and at-fault MVC involvement. We examined whether the associations differed by higher order visual processing impairment status, as measured by Useful Field of View, Trails B, and Motor-free Visual Perception Test. Rates of crash involvement were similar for older adults who have ever driven with a pet compared to those who never drove with their pet (RR=1.15, 95% CI 0.76-1.75). Drivers who reported always or sometimes driving with their pet had higher MVC rates compared to pet owners who never drive with a pet, but this association was not statistically significant (RR=1.39, 95% CI 0.86-2.24). In terms of location, those reporting having a pet frequently ride in the front of the vehicle had similar rates of MVC involvement compared to those who did not drive with a pet in the front. A similar pattern of results was observed for at-fault MVCs. This association was not modified by visual processing impairment status. The current study demonstrates a positive but non-significant association between frequently driving with pets and MVC involvement. More research is needed, particularly on restraint use and whether the pet was in the car at the time of the crash, to help characterize the public safety benefit of regulations on driving with pets.

Although nurses play an important role in end-of-life care for patients, they are not systematically involved in end-of-life decisions with a possible or certain life-shortening effect (ELDs). Until now we know little about factors relating to the involvement of nurses in these decisions. To explore which patient- and decision-characteristics are related to the consultation of nurses and to the administering of life-ending drugs by nurses in actual ELDs in institutions and home care, as reported by physicians. We sampled at random 5005 of all registered deaths in the second half of 2001--before euthanasia was legalized--in Flanders, Belgium. We mailed anonymous questionnaires to physicians who signed the death certificates and asked them to report on ELDs, including nurses' involvement. Response rate was 59% (n=2950). Physicians reported nurses involved in decision making more often in institutions than at home, and more often in care homes for the elderly than in hospitals (OR 1.70, 95% CI 1.15, 2.52). This involvement was more frequently when physicians intended to hasten the patient's death than when they had no such intention (institutions: OR 2.05, 95% CI 1.41, 2.99; home: OR 2.04, 95% CI 1.19, 3.49). In institutions, this involvement was also more likely where patients were of lower rather than higher education (OR 2.95, 95% CI 1.49, 5.84). The administering of life-ending drugs by nurses, as reported by physicians was also found more frequently in institutions than at home, and in institutions more frequently with lower rather than higher educated patients (p=.037). These findings raise questions about physicians' perception of the nurse's role in ELDs, but also about physicians' skills in interacting with all patients. Education and guidelines for physicians and nurses are needed to optimize good communication and to promote a clearer assignment of responsibilities concerning the execution of those decisions.

2015-01-01

Distracted driving contributes to a large proportion of motor vehicle crashes, yet little is known about the prevalence of distracted driving and the specific types of distracting behaviors. The objective of this study was to estimate the prevalence of driver distraction using a roadside observational study design. A cross-sectional survey involving direct roadside observation was conducted at 11 selected intersections. Trained investigators observed a sample of passenger vehicles and recorded distraction-related behaviors, driver characteristics, and contextual factors such as vehicle speed and traffic flow. Of the 3,265 drivers observed, the prevalence of distracted driving was 32.7%. Among those involved in a distracting activity, the most frequently observed distractions included interacting with another passenger (53.2%, where passengers were present), talking on the phone (31.4%), external-vehicle distractions (20.4%), and texting/dialing a phone (16.6%). The prevalence of talking on the phone was higher among females than males (38.6% vs. 24.3%), whereas external vehicle distractions were higher among males than females (25.8% vs. 24.3%). Drivers <30 years were observed being engaged in any distracting activity, interacting with other passengers, and texting/dialing more frequently than drivers aged 30-50 and >50 years. Drivers were engaged in distracting behaviors more frequently when the car was stopped. When using similar methodology, roadside observational studies generate comparable prevalence estimates of driver distraction as naturalistic driving studies. Driver distraction is a common problem among passenger vehicle drivers. Despite the increased awareness on the dangers of texting and cell phone use while driving, these specific activities were 2 of the most frequently observed distractions. There is a continued need for road safety education about the dangers of distracted driving, especially for younger drivers.

2011-01-01

Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, inflammatory neurodegenerative disease. This study investigated the relationships of clinical stage with epidemiological and magnetic resonance imaging (MRI) findings in SSPE by retrospective review of 76 cases (57 male) diagnosed by typical periodic electroencephalographic features, clinical symptoms and elevated measles antibody titre in cerebrospinal fluid. Clinical stage at diagnosis was I or II in 48 patients, III in 25 and IV in three. Prominent findings at presentation were atonic/myoclonic seizures (57.9%) and mental deterioration with behaviour alteration (30.3%). Frequent MRI findings (13 - 32 patients) were subcortical, periventricular and cortical involvement and brain atrophy; the corpus callosum, basal ganglia, cerebellum and brainstem were less frequently involved. Five patients had pseudotumour cerebri. Cranial MRI at initial diagnosis was normal in 21 patients (19 stage I/II, two stage III/IV). Abnormal MRI findings were significantly more frequent in the later stages, thus a normal initial cranial MRI does not exclude SSPE, which should, therefore, be kept in mind in childhood demyelinating diseases even when the presentation is unusual.

2015-09-01

At disease onset, children with acute lymphoblastic leukaemia (ALL) may present with arthralgia or even signs of arthritis. This might cause misdiagnosis and thereby lead to prolonged diagnostic delay. The present study aimed to identify children with ALL with joint involvement and to compare their characteristics and outcome with children with ALL without joint involvement. Case records of 286 children diagnosed with ALL between 1992 and 2013 were reviewed and analysed in this retrospective, descriptive study. Fifty-three (18.5%) children with ALL presented with localised joint pain, and half of them had objective signs of arthritis. The mean number of joints involved was 2.5, most frequently presenting as asymmetric oligoarthritis. The suspected misdiagnosis were reactive arthritis (19/53), osteomyelitis (9/53) and juvenile idiopathic arthritis (8/53). Children with joint involvement had less objective signs of haematological disease. Cytopenia was absent in 24% in children with joint involvement (vs 8% without, p=0.001), 50% had only one cell line affected (vs 21%, p=0.0005) and 44% had no organomegaly (vs 29%, p=0.05). Median diagnostic delay was 4 vs 2 weeks. The 5-year event-free and overall survival was superior for children with joint involvement: 94% vs 87% (p=0.049), and 96% vs 83% (p=0.044). ALL with joint involvement is a frequent finding (18.5%). The clinical signs of leukaemia are less prominent, but non-articular pain should alert the clinician of a possible diagnosis of leukaemia. The overall and event-free survivals were superior compared with the children without joint involvement. Published by the BMJ Publishing Group Limited.

To describe clinical, ultrasonographic, and computed tomographic (CT) features of confirmed neoplastic and nonneoplastic disease in dogs with unilateral orbital diseases, determine criteria to differentiate between the 2 conditions, and assess the relative value of ultrasonography and CT for the differential diagnosis of these 2 conditions. Prospective study. 29 dogs with unilateral neoplastic orbital disease and 16 dogs with unilateral nonneoplastic orbital disease. Clinical history and results of physical and ophthalmologic examinations were recorded. Ultrasonographic and CT images were evaluated, and discriminating factors were identified to differentiate neoplastic from nonneoplastic diseases. Diagnostic value of ultrasonography and CT was assessed. Dogs with neoplastic disease were significantly older; had clinical signs for a longer time before initial examination; had more progressive onset of clinical signs; and more frequently had protrusion of the nictitating membrane, fever, and anorexia. The most discriminating factor for both imaging modalities was delineation of the margins (odds ratio was 41.7 for ultrasonography and 45 for CT), with neoplastic lesions clearly delineated more often. Ultrasonographically, neoplastic lesions were more frequently hypoechoic and homogeneous, with indentation of the globe and bone involvement evident more frequently than for nonneoplastic lesions. Mineralization was detected only with neoplasia. Fluctuant fluid was seen more frequently in dogs with nonneoplastic disease. Computed tomography more frequently revealed extraorbital involvement. Diagnostic value was similar for both imaging modalities. Ultrasonography and CT are valuable imaging modalities to assist in differentiating neoplastic from nonneoplastic unilateral orbital disease in dogs.

Involvement of the central nervous system by sarcoidosis, also referred to as neurosarcoidosis, is seen clinically in about 5% of patients with systemic disease. CNS involvement most frequently affects the leptomeninges and cranial nerves, though the ventricular system, brain parenchyma, and pachymeninges may also be involved. Even though the involvement of the intracranial vascular structures is well-known on postmortem studies, there is scant literature on imaging manifestations secondary to the vessel wall involvement, being confined mostly to isolated case reports and small series. The authors present a review of various cerebrovascular manifestations of neurosarcoidosis, along with a brief synopsis of the existing literature. © 2018 by American Journal of Neuroradiology.

Brucellosis is the most prevalent bacterial zoonosis worldwide. In this study, we aimed to compare our 1028 brucellosis cases with other big series in the literature in view of epidemiological, clinical, and laboratory findings and therapeutic features. A total of 1028 brucellosis cases admitted to the Department of Infectious Diseases and Clinical Microbiology over a 10-year period were included in the study. A retrospective analysis was undertaken and patient files were reviewed for history, clinical and laboratory findings, and therapeutic features, as well as complications. Of the 1028 patients, 539 (52.4%) were female and 489 (47.6%) were male. The mean age of patients was 33.7+/-16.34 years and 69.6% of cases were aged 13-44 years. Four hundred and thirty-five cases (42.3%) had a history of raising livestock and 55.2% of the cases were found to have no occupational risk for brucellosis. Six hundred and fifty-four of the cases (63.6%) had a history of raw milk and dairy products consumption. The most frequently seen symptoms were arthralgia (73.7%) and fever (72.2%), while the most common clinical findings were fever (28.8%) and hepatomegaly (20.6%). The most frequent laboratory finding was a high C-reactive protein level (58.4%). The standard tube agglutination (STA) test+Coombs STA test was positive in 1016 cases (98.8%). Focal involvement was present in 371 (36.1%) cases. The most frequent involvement was osteoarticular involvement with 260 cases (25.3%). The overall relapse rate for patients with brucellosis was 4.7%. The highest relapse rate, 8.5%, was observed in the group of patients with osteoarticular involvement. Regimens including doxycycline and streptomycin with or without rifampin appeared more effective than other regimens in osteoarticular involvement. In humans, brucellosis may lead to serious morbidity, and it continues to be a major health problem in Turkey. There is no recommended treatment protocol for complicated brucellosis. Large multicenter studies are needed to determine the most appropriate treatment choices and durations in complicated brucellosis. Copyright 2009 International Society for Infectious Diseases.

Duchenne (DMD) and Becker (BMD) muscular dystrophies are X-linked recessive disorders associated with both skeletal myopathy and progressive cardiomyopathy in males. Female DMD/BMD carriers (DMDc/BMDc) are mostly free of skeletal muscle symptoms, but they are also prone to cardiomyopathy. The aim of the current study was to characterize the frequency, pattern, and extent of cardiomyopathy in female DMD/BMD carriers (DMDc/BMDc) in comparison to their first-degree male MD relatives. Thirty-six (age 44 ± 14 years) female MD carriers (20 DMDc and 16 BMDc) constituted the 'MD carrier group' and were prospectively enrolled. All MD carriers underwent a complete CMR study comprising cine- and late gadolinium enhancement (LGE) imaging. In 22 of these women ('female MD carrier comparison group', 7 DMD and 15 BMD), at least one first-degree male relative with a previously established diagnosis of MD underwent the same CMR protocol and was assigned to the 'male MD comparison group' (n = 24, 6 DMD and 18 BMD). In the total MD carrier group, 17 (47%) MD carriers had at least one pathological CMR finding [5 (14%) with a reduced left ventricular ejection fraction (LV-EF) and 16 (44%) with the presence of LGE]. All LGE-positive patients (n = 16) showed non-ischaemic LGE with subepicardial involvement of the LV lateral free wall being the most frequent pattern (13/16, 81%). Compared with BMDc, DMDc demonstrated more frequently a pathological CMR result (65 vs. 19%; P = 0.008)--in spite of being significantly younger (40 ± 11 vs. 50 ± 16 years, P = 0.038). In the male MD comparison group, the same LGE pattern as in female carriers was seen, but with a significantly higher prevalence of cardiac abnormalities compared with their female carrier relatives constituting the female MD comparison group (75 vs. 27%; P = 0.003).

[Involvement of mucous membranes in autoimmune bullous diseases].

PubMed

Günther, C

2016-10-01

Autoimmune bullous diseases are characterized by intraepidermal or subepidermal autoantibody deposition that leads to blisters and secondary erosion. Mucous membranes are frequently affected in pemphigus vulgaris and always involved in cicatricial and mucosal pemphigoid. Mucosal lesions are detected less frequently in patients with bullous pemphigoid or epidermolysis bullosa acquisita. The diagnosis of autoimmune bullous disorders is based on determination of the subtype of autoantibodies bound in the skin and the clinical picture. Treatment is based on immunosuppression related to the type of disease and severity of the mucosal symptoms. Ocular involvement in mucosal pemphigoid and pemphigus vulgaris requires systemic treatment.

Nephrourologic malformations in Turner syndrome are frequent, its diagnosis and follow-up is important in order to diminish the morbidity of this disease. The aim of this retrospective study was to analyze the nephrourologic pathology in 72 girls with Turner syndrome followed between 1989 and 2008 at Garrahan Hospital. The prevalence of nephrourologic involvement was 33% (24 patients). The most frequent findings were urinary system malformations, isolated (10 pacientes, 42%) or associated with renal malformations (9 patients, 37%); 5 patients (21%) had only renal malformations. Fifty percent of patients developed complications (8 urinary tract infection, 2 proteinuria and 2 arterial hypertension); however, none progressed to chronic renal failure. The prevalence of nephrourologic involvement was 33% and a half of these girls developed complications, our findings show the need of routine nephrological follow-up of girls with Turner syndrome and nephrourologic malformations.

Pyrogen release in vitro by lymphoid tissues from patients with Hodgkin's disease.

PubMed

Bodel, P

1974-01-01

The mechanism of fever in patients with Hodgkin's disease was investigated by examining endogenous pyrogen production by blood, spleen, and lymph node cells incubated in vitro. Blood leucocytes from febrile or afebrile patients with Hodgkin's disease did not produce pyrogen spontaneously. Spleen cells, however, frequently released pyrogen during initial incubations, unlike spleen cells from patients with non-malignant diseases. Pyrogen production occurred from spleens without observed pathologic infiltrates of Hodgkin's disease. Lymph nodes involved with Hodgkin's disease produced pyrogen more frequently than did nodes involved with other diseases. Pyrogen production by tissue cells was prolonged, required protein synthesis, and in some cases was due to mononuclear cells; it did not correlate with fever in the patient. These studies demonstrate spontaneous production of endogenous pyrogen in vitro by lymphoid tissue cells from patients with Hodgkin's disease.

This is the first study to examine the extent to which frequent involvement in high-school bullying (as a bullying perpetrator, victim of bullying, or bully-victim) increases the risk for later depression and suicidality beyond other well-established risk factors of suicide. The study included 96 students who reported being a bully, a victim, or a bully-victim, and also reported depression, suicidality, or substance problems during an initial suicide screen. These students were interviewed 2 years later and were compared with 142 youth identified during the initial screen as "suicide-at-risk" by virtue of their depression, suicidal ideation, attempts, and substance problems, but who did not report any involvement in bullying behavior. Students who reported both bullying others and other suicide-related behaviors at baseline had higher suicide ideation and were more functionally impaired at follow-up than students who reported suicide-related behaviors but were not involved in bullying. Preventive efforts in high school should target those children who are characterized by both psychological disturbance and bullying, especially the frequent bullies.

Voitzuk, Ana; Greco, Vanina; Caputo, Daniel; Alvarez, Estela

2014-01-01

Toxic nephrophaties secondary to occupational exposure to metals have been widely studied, including membranous nephropathy by mercury, which is rare. Occupational poisoning by mercury is frequent, neurological symptoms are the main form of clinical presentation. Secondary renal involvement in chronic exposure to metallic mercury can cause glomerular disease by deposit of immune-complexes. Membranous glomerulopathy and minimal change disease are the most frequently reported forms. Here we describe the case of a patient with occupational exposure to metallic mercury, where nephrotic syndrome due to membranous glomerulonephritis responded favorably to both chelation and immunosuppressive therapy.

To evaluate the incidence and pathologic correlation of thin-section computed tomography (TSCT) findings in smoking-related interstitial fibrosis (SRIF) with pulmonary emphysema. Our study included 172 consecutive patients who underwent TSCT and subsequent lobectomy. TSCT findings including clustered cysts with visible walls (CCVW) and ground-glass attenuation with/without reticulation (GGAR) were evaluated and compared in nonsmokers and smokers and among lung locations. TSCT findings, especially CCVW, were also compared with histological findings using lobectomy specimens. The incidence of CCVW and GGAR was significantly higher in smokers than in nonsmokers (34.1% and 40.7%, respectively, vs 2.0% and 12.2%). CCVW and GGAR were frequently found in the lower and peripheral zones. Histologically, CCVW corresponded more often with SRIF with emphysema than usual interstitial pneumonia (UIP, 63.3% vs 30%). CCVW of irregular size and shape were seen in 19 of 20 SRIF with emphysema and in seven of nine UIP-manifested areas with similar round cysts. A less-involved subpleural parenchyma was observed more frequently in SRIF with emphysema. SRIF with emphysema is a more frequent pathological finding than UIP in patients with CCVW on TSCT. The irregular size and shape of CCVW and a less-involved subpleural parenchyma may be a clue suggesting the presence of SRIF with emphysema.

Hepatitis C virus-related arthritis.

Palazzi, Carlo; D'Angelo, Salvatore; Olivieri, Ignazio

2008-10-01

Although asymptomatic joint involvement and arthralgias are frequent in patients with hepatitis C virus chronic infection (HCV), a true arthritis affects only up to 4% of the subjects. HCV-related arthritis (HCVrA) is usually distinguished in two clinical subsets: a more frequent symmetrical polyarthritis (SP), similar to rheumatoid arthritis but much less serious, and an intermittent mono-oligoarthritis (IMO) that involves medium and large sized joints, mainly the ankle. This latter subset is strictly related to the presence of HCV-induced mixed cryoglobulinemia and its cutaneous manifestations, in particular purpura. According to recent reports, anti-CCP antibodies are considered very useful in differentiating the SP subset from rheumatoid arthritis. The treatment of HCVrA is still largely empirical because few studies have analyzed this topic. However, COXIBs, NSAIDs, low doses of corticosteroids, hydroxychloroquine and less frequently methotrexate and penicillamine have been used with partial or complete control of symptoms. On the basis of recent studies, the administration of cyclosporine also seems to be sufficiently safe. The scarcely aggressive nature of HCVrA does not favour the use of anti-TNF agents. Specific anti-viral therapy (interferon-alpha+ribavirin) must be accurately evaluated because interferon-alpha can induce the development or the worsening of several autoimmune HCV-related disorders including arthritis.

Background and aim This review aims at presenting a current view on the most frequent factors involved in the mechanisms causing temporomandibular disorders (TMD). Method We conducted a critical review of the literature for the period January 2000 to December 2014 to identify factors related to TMD development and persistence. Results The etiology of TMD is multidimensional: biomechanical, neuromuscular, bio-psychosocial and biological factors may contribute to the disorder. Occlusal overloading and parafunctions (bruxism) are frequently involved as biomechanical factors; increased levels of estrogen hormones are considered biological factors affecting the temporo-mandibular-joint. Among bio-psychosocial factors, stress, anxiety or depression, were frequently encountered. Conclusions The etiopathogenesis of this condition is poorly understood, therefore TMDs are difficult to diagnose and manage. Early and correct identification of the possible etiologic factors will enable the appropriate treatment scheme application in order to reduce or eliminate TMDs debilitating signs and symptoms.

To determine the clinical profile, degree of involvement and management in patients with knee, hip or hand osteoarthritis. Observational study (health centers from 14 autonomous regions, n=363 primary care physicians), involving patients with clinical and/or radiological criteria for osteoarthritis from the American College of Rheumatology, consecutively selected (n=1,258). Sociodemographic variables, clinical and radiological findings, comorbidity and therapeutic management were analyzed. Mean age was 68.0±9.5 years old; 77.8% were women and 47.6% obese. Distribution by location was: 84.3% knee, 23.4% hip, 14.7% hands. All patients reported pain. The most frequent radiographic Kellgren-Lawrence grade was stage 3 for knee and hip (42.9% and 51.9%, respectively), and 3 (37.2%) and 2 (34.5%) for hip. Time since onset of osteoarthritis symptoms was 9.4±7.5 years, with a mean age at onset of around 60 years old and a family history of osteoarthritis in 66.0%. The most frequent comorbidities were: hypertension (55.1%), depression/anxiety (24.7%) and gastroduodenal diseases (22.9%). A total of 97.6% of the patients received pharmacological treatment, with oral analgesics (paracetamol) (70.5%) and oral NSAIDs (67.9%) being the most frequent drugs. Bilateral osteoarthritis was present in 76.9% of patients with knee osteoarthritis, 59.3% in hip and 94.7% in hands. Female gender and time since onset were associated with bilateral knee and hip osteoarthritis. The profile of the osteoarthritis patient is female, >65 years old, overweight/obese, with comorbidity, frequent symptoms and moderate radiologic involvement. Most of patients had bilateral osteoarthritis, associated with female gender and time since onset of disease. Paracetamol was the most common pharmacological treatment.

Child involvement and stress in Greek mothers of deaf children.

PubMed

Lampropoulou, V; Konstantareas, M M

1998-10-01

Forty-two mothers of Greek deaf children reported their level of stress, availability of support, duration and frequency of involvement with their children, and affective tone of involvement, using an adaptation of Hill's ABCX model of stress and support (1949). Data on the interaction among six caregiving categories were collected over a 2-day period. Mothers of younger children and of boys, as well as mothers reporting greater stress, had longer and more frequent involvement. Mothers with greater stress were also more likely to rate the affective tone of their involvement as more neutral or as chorelike. Support availability was unrelated to involvement, with the exception of supporting neighbors. Compared to Canadian mothers of children both with and without disabilities, exposed to the same study protocol, the mothers in the present study were not more stressed. However, they were more likely to report a negative affective tone in their caregiving.

Awakening, Breathing Coordination, Delirium, and Early Mobility bundle (ABCDE) should involve an interprofessional team, yet no studies describe what team composition supports implementation. We administered a survey at MHA Keystone Center ICU 2015 workshop. We measured team composition by the frequency of nurse, respiratory therapist, physician, physical therapist, nurse practitioner/physician assistant or nursing assistant involvement in 1) spontaneous awakening trials (SATs), 2) spontaneous breathing trials, 3) delirium and 4) early mobility. We assessed ABCDE implementation using a 5-point Likert ("routine part of every patient's care" - "no plans to implement"). We used ordinal logistic regression to examine team composition and ABCDE implementation, adjusting for confounders and clustering. From 293 surveys (75% response rate), we found that frequent nurse [OR 6.1 (1.1-34.9)] and physician involvement [OR 4.2 (1.3-13.4)] in SATs, nurse [OR 4.7 (1.6-13.4)] and nursing assistant's involvement [OR 3.9 (1.2-13.5)] in delirium and nurse [OR 2.8 (1.2-6.7)], physician [OR (3.6 (1.2-10.3)], and nursing assistants' involvement [OR 2.3 (1.1-4.8)] in early mobility were significantly associated with higher odds of routine ABCDE implementation. ABCDE implementation was associated with frequent involvement of team members, suggesting a need for role articulation and coordination. Copyright © 2017 Elsevier Inc. All rights reserved.

Nailfold capillaroscopic changes in patients with systemic lupus erythematosus: correlations with disease activity, skin manifestation and nephritis.

2017-08-01

Introduction The clinical expression of systemic lupus erythematosus (SLE) is the consequence of endothelial cell damage leading to serious multiple organ dysfunction. The aim of this study was to assess the association between nailfold capillaroscopic changes and disease activity, skin and renal involvement in patients with SLE. Methods Demographic variables, clinical manifestations and laboratory data of 108 patients with SLE were investigated. Nailfold capillaroscopy (NFC) was performed in all patients. Result Morphological changes in NFC were observed in 102 out of 108 (94.4%) SLE patients. Minor changes were found in 33 (30.6%) and major changes in 69 (63.9%) cases. The disease activity was significantly higher in the patients with major changes ( p < 0.002). A higher incidence of microhaemorrhages was seen in patients with active SLE disease ( p < 0.04). In SLE patients with active skin involvement, the disturbed distribution ( p < 0.004) was more frequent and subtle changes ( p < 0.009) were less frequently observed as compared with patients without active skin involvement. In the group of SLE patients with renal involvement, no correlation was found between the capillary abnormalities and the presence of renal involvement ( p > 0.05), except for the elongated capillary loops, which were seen more often in patients with renal involvement than in patients without it ( p < 0.03). Conclusion The results of the study showed that capillary changes (abnormal capillaroscopy) were very common in patients with SLE, although there were no specific patterns like the ones in scleroderma patients, and some changes may be associated with disease activity, especially in patients with active skin involvement.

Involvement of the peripheral nervous system in mitochondrial disorders (MD) has been previously reported. However, the exact prevalence of peripheral neuropathy and/or myopathy in MD is still unclear. In order to evaluate the prevalence of neuropathy and myopathy in MD, we performed sensory and motor nerve conduction studies (NCS) and concentric needle electromyography (EMG) in 44 unselected MD patients. NCS were abnormal in 36.4% of cases, and were consistent with a sensori-motor axonal multineuropathy (multifocal neuropathy), mainly affecting the lower limbs. EMG evidence of myopathy was present in 54.5% of patients, again mainly affecting the lower limbs. Nerve and muscle involvement was frequently subclinical. Peripheral nerve and muscle involvement is common in MD patients. Our study supports the variability of the clinical expression of MD. Further studies are needed to better understand the molecular basis underlying the phenotypic variability among MD patients.

To assess the neurological involvement and outcome, including school and professional performances, of adults and children with cryopyrin-associated periodic syndrome (CAPS). In this observational study, patients with genetically proven CAPS and followed in the national referral centre for autoinflammatory diseases at Bicêtre hospital were assessed. Neurological manifestations, CSF data and MRI results at diagnosis and during follow-up were analyzed. Twenty-four patients (15 adults and 9 children at diagnosis) with CAPS were included. The median age at disease onset was 0 year (birth) [range 0-14], the median age at diagnosis was 20 years [range 0-53] and the mean duration of follow-up was 10.4 ± 2 years. Neurological involvement at diagnosis, mostly headaches and hearing loss, was noted in 17 patients (71%). Two patients of the same family had abnormal brain MRI. A439V mutation is frequently associated with a non-neurological phenotype while R260W mutation tends to be associated with neurological involvement. Eleven adult patients (61%) and 3 children (50%) underwent school difficulties. Neurological involvement is frequent in patients with CAPS and the majority of patients presented difficulties in school performances with consequences in the professional outcome during adulthood. Further studies in larger cohorts of children with CAPS focusing in intellectual efficiency and school performances are necessary.

2018-01-01

Background The purpose of the present study was to evaluate changing pattern in characteristics of maxillofacial fractures and concomitant injuries in Western Libya During revolution and to assess the association between mechanism of injury and fracture patterns. Material and Methods A retrospective review of medical records and radiographs of 187 patients treated for maxillofacial fractures from January 2010 to December 2012 was performed, there were 326 fractures in 187 patients. Results The male: female ratio was 6:1. Most fractures occurred in patients aged 11 to 40 years, and few injuries occurred in patients aged > 50 years. Most fractures occurred from motor vehicle accidents, and other most frequent causes included assault, gunshot, and fall injuries. Most maxillofacial fractures involved the mandible, zygomatic complex, or maxilla. Most mandibular fractures occurred at the parasymphysis, angle, or condyle. Associated injuries most frequently involved the head, chest, and extremities. Most patients were treated with open reduction (132 patients [71%]), and 26 patients (14%) were treated nonoperatively. There were 21 complications (11%). Conclusions In summary, motor vehicle accidents were the most frequent cause of maxillofacial fracture in western Libya, possibly because of the lack of seat belt legislation. Interpersonal violence was a less frequent cause of maxillofacial fracture, possibly because of the religious restriction on alcohol consumption. Key words:Tauma, mandible, zygomatic complex, maxilla, treatment, complications. PMID:29476683

Effect of herd cues and product involvement on bidder online choices.

PubMed

Chen, Yi-Fen; Wang, Ya-Ju

2010-08-01

Previous works have shown that consumers are influenced by others in decision making. Herd behavior is common in situations in which consumers infer product quality from other consumer choices and incorporate that information into their own decision making. This research presents two studies examining herd effect and the moderating role of product involvement on bidder choices in online auctions. The two studies addressed the influence on bidder online choices of herd cues frequently found in online auctions, including feedback ratings and number of questions and answers. The experimental results demonstrated that bidders use online herd cues when making decisions in online auctions. Additionally, the effects of herd cues on bidder online choices were stronger in high-involvement than low-involvement participants. Results and implications are discussed.

Driving with pets and motor vehicle collision involvement among older drivers: a prospective population-based study

PubMed Central

Huisingh, Carrie; Levitan, Emily B.; Irvin, Marguerite R.; Owsley, Cynthia; McGwin, Gerald

2016-01-01

Objective Distracted driving is a major cause of motor vehicle collision (MVC) involvement. Pets have been identified as potential distraction to drivers, particularly in the front. This type of distraction could be worse for those with impairment in the cognitive aspects of visual processing. The purpose of this study is to evaluate the association between driving with pets and rates of motor vehicle collision involvementin a cohort of older drivers. Methods A three-year prospective was conducted in a population-based sample of 2000 licensed drivers aged 70 years and older. At the baseline visit, a trained interviewer asked participants about pet ownership, whether they drive with pets, how frequently, and where the pet sits in the vehicle. Motor vehicle collision (MVC) involvement during the three-year study period was obtained from the Alabama Department of Public Safety. At-fault status was determined by the police officer who arrived on the scene. Participants were followed until the earliest of death, driving cessation, or end of the study period. Poisson regression was used to calculate crude and adjusted rate ratios (RR) examining the association between pet ownership, presence of a pet in a vehicle, frequency of driving with a pet, and location of the pet inside with vehicle with any and at-fault MVC involvement. We examined whether the associations differed by higher order visual processing impairment status, as measured by Useful Field Of View, Trails B, and Motor-free Visual Perception Test. Results Rates of crash involvement were similar for older adults who have ever driven with a pet compared to those who never drove with their pet (RR=1.15, 95% CI 0.76-1.75). Drivers who reported always or sometimes driving with their pet had higherMVC rates compared topet owners who never drive with a pet, but this association was not statistically significant (RR=1.39, 95% CI 0.86-2.24). In terms of location, those reporting having a pet frequently ride in the front of the vehicle had similar rates of MVC involvement compared to those who did not drive with a pet in the front. A similar pattern of results was observed for at-fault MVCs. This association was not modified by visual processing impairment status. Conclusion The current study demonstrates a positive but non-significant association between frequently driving with pets and MVC involvement. More research is needed, particularly on restraint use and whether the pet was in the car at the time of the crash, to help characterize the public safety benefit of regulations on driving with pets.

The mastoid portion of the temporal bone has multiple functional roles in the organism, including regulation of pressure in the middle ear and protection of the inner ear. We investigated whether mastoid pneumatization plays a role in the protection of vital structures in the temporal bone during direct lateral trauma. The study was performed on 20 human temporal bones isolated from cadavers. In the study group formed by 10 temporal bone samples, mastoid cells were removed and the resulting neocavities were filled. The mastoids were maintained intact in the control group. All samples were impacted at the same speed and kinetic energy. The resultant temporal bone fractures were evaluated by CT. Temporal squama fractures were 2.88 times more frequent, and mastoid fractures were 2.76 times more frequent in the study group. Facial nerve canal fractures were 6 times more frequent in the study group and involved all the segments of the facial nerve. Carotid canal fractures and jugular foramen fractures were 2.33 and 2.5 times, respectively, more frequent in the study group. The mastoid portion of the temporal bone plays a role in the absorption and dispersion of kinetic energy during direct lateral trauma to the temporal bone, reducing the incidence of fracture in the setting of direct trauma. © 2014 by American Journal of Neuroradiology.

2016-11-01

The aims of the study were to determine the prevalence of energy drink consumption by adolescents, to identify associated clinical symptoms and adverse effects, and to gain an understanding to the motivation behind its consumption. A prospective, questionnaire-based study was conducted at 2 emergency departments from June 2011 to June 2013. The questionnaire was distributed to a convenience sample of adolescents aged 12 to 18 years. Stratification was performed on the basis of frequency of consumption: frequent consumption (at least once a month) and infrequent consumption (less frequent than once a month). Data analysis was performed on 612 completed questionnaires. Two hundred two responders (33%) were considered frequent energy drink consumers. Frequent consumers were more likely to be involved in high-risk behaviors and more likely to consume other caffeinated drinks. In the previous 6 months, frequent energy drink consumers were more likely to report headache (76%), anger (47%), and increased urination (24%) and were more likely to require medical evaluation for headache (41%) and difficulty breathing (22%). Frequent energy drink consumers were more likely to believe that energy drinks "help me do better in school" (12%), "help me do better in sports" (35%), "are just for fun" (46%), "help me stay up at night" (67%), and "make me concentrate/focus better" (34%). Clarifying common misconceptions associated with energy drink consumption, especially in high-risk adolescents and frequent energy drink consumers, may decrease the frequency of symptoms experienced by adolescents, such as headache and difficulty breathing, requiring medical evaluation.

Although stingray injuries have always been frequent in the Republic of Djibouti, it was not until July 2008 that the Bouffard Hospital developed a standardised management protocol. The purpose of this report is to describe that protocol and evaluate its impact on the outcome of stingray injuries based on a prospective study for the period between July 2008 and July 2009. During the study period, 12 stingray stings were treated. The treatment protocol that is based on a multidisciplinary approach involving the intensivist, anaesthesiologist, and surgeon achieved wound healing within one month. This outcome contrasts with previous publications that have generally described longer healing times with frequent infectious complications.

2012-12-01

Hyper-frequentation in health services is a problem for patients, their families and the institutions. This study is aimed at determining the frequency and characteristics of common mental disorders in hyper-frequent patients showing vague symptoms and signs at a primary healthcare service during the year 2007 in the city of Cali (Colombia). Cross sectional. The most frequent mental disorders in hyper-frequent patients were detected through a telephone interview which included several modules of the PRIME MD instrument. In general, healthcare service hyper-frequenters are working women, 38,7-year old in average. Basically, the consultation is due to cephalalgia but they also exhibit a high prevalence of common mental disorders (somatization, depression and anxiety) not easily diagnosed by physicians in primary care. Expenses for additional health activities generated by these patients are attributed basically to medical consultation and required procedures. Considering hyper-frequenters in health care services as a risk group in terms of common mental disorders involves screening as an efficient strategy to prevent abuse in service use and to improve satisfaction with the attention received.

Although numerous studies suggest that religious involvement is associated with a wide range of favorable health outcomes, it is unclear whether this general pattern extends to cellular aging. In this paper, we tested whether leukocyte telomere length varies according to several dimensions of religious involvement. We used cross-sectional data from the Nashville Stress and Health Study (2011-2014), a large probability sample of 1252 black and white adults aged 22 to 69 living in Davidson County, TN, USA. Leukocyte telomere length was measured using the monochrome multiplex quantitative polymerase chain reaction method with albumin as the single-copy reference sequence. Dimensions of religious involvement included religiosity, religious support, and religious coping. Our multivariate analyses showed that religiosity (an index of religious attendance, prayer frequency, and religious identity) was positively associated with leukocyte telomere length, even with adjustments for religious support, religious coping, age, gender, race, education, employment status, income, financial strain, stressful life events, marital status, family support, friend support, depressive symptoms, smoking, heavy drinking, and allostatic load. Unlike religiosity, religious support and religious coping were unrelated to leukocyte telomere length across models. Depressive symptoms, smoking, heavy drinking, and allostatic load failed to explain any of the association between religiosity and telomere length. To our knowledge, this is the first population-based study to link religious involvement and cellular aging. Although our data suggest that adults who frequently attend religious services, pray with regularity, and consider themselves to be religious tend to exhibit longer telomeres than those who attend and pray less frequently and do not consider themselves to be religious, additional research is needed to establish the mechanisms underlying this association.

2012-11-01

Indications for thyroidectomy during laryngectomy are controversial. We examined whether clinicopathologic features can predict thyroid gland involvement, and the prognostic effect of thyroid gland involvement in patients undergoing total laryngectomy. The study set out to review preoperative assessment, operation findings, pathologic findings, and follow-up data. Thyroid gland involvement was found in 11 of 53 patients (21%) undergoing total laryngectomy and thyroidectomy. Preoperative work-up failed to predict thyroid gland involvement. Thyroid gland involvement was associated with salvage procedures (p = .025), paratracheal metastases (p = .003), and poor overall survival (hazard ratio = 2.74, p = .008). Thyroid gland involvement in patients undergoing total laryngectomy is frequent and is associated with poor prognosis. Preoperative assessment failed to predict thyroid gland involvement. We believe that thyroidectomy should be considered in cases with paratracheal lymphatic spread irrespective of tumor location within the larynx. Copyright © 2011 Wiley Periodicals, Inc.

Product involvement and consumer food-elicited emotional associations: Insights from emoji questionnaires.

PubMed

Jaeger, Sara R; Lee, Pui-Yee; Ares, Gastón

2018-04-01

Individual differences in food-related consumer behaviour are well documented, but lack thorough exploration in relation to product-elicited emotional associations. In this research, focus is directed to product involvement as a factor that modulates emotional associations to tasted products (dried fruit, n = 4) and written descriptions of consumption situations (drinking red wine, cooking dinner using seafood). Emoji questionnaires were used (as check-all-that-apply questions: CATA), and across two studies with consumers in New Zealand (n = 352) and China (n = 450), higher levels of involvement were associated with more positive emotional associations. For example, consumers with higher involvement for dried fruit used emoji with positive meanings (e.g., face savouring delicious food (), smiling face with heart-shaped eyes () and smiling face with smiling eyes () more frequently than those with lower levels of involvement. Conversely, emoji with negative or neutral meanings (e.g., confused face (), confounded face (), neutral face ()), were more frequently used by consumers with lower levels of product involvement. The number of significant differences between the samples of dried fruit were lower in the less involved consumer segment, and these consumers, on average, used less emoji to characterise the samples. A similar pattern of results were established for the written stimuli, which were used with Chinese consumers. For example, in the segment with greater involvement with seafood, associations to emoji with positive meanings were higher when responding to the situation "cooking dinner using frozen seafood as one of the ingredients." In the case of "drinking French red wine," the strategy used to define segments (median vs. triadic split of summed involvement scores) additionally influenced the results, and bigger differences were established when comparing more discrete segments (two extreme groups following triadic split).

Purpose To evaluate the incidence and pathologic correlation of thin-section computed tomography (TSCT) findings in smoking-related interstitial fibrosis (SRIF) with pulmonary emphysema. Patients and methods Our study included 172 consecutive patients who underwent TSCT and subsequent lobectomy. TSCT findings including clustered cysts with visible walls (CCVW) and ground-glass attenuation with/without reticulation (GGAR) were evaluated and compared in nonsmokers and smokers and among lung locations. TSCT findings, especially CCVW, were also compared with histological findings using lobectomy specimens. Results The incidence of CCVW and GGAR was significantly higher in smokers than in nonsmokers (34.1% and 40.7%, respectively, vs 2.0% and 12.2%). CCVW and GGAR were frequently found in the lower and peripheral zones. Histologically, CCVW corresponded more often with SRIF with emphysema than usual interstitial pneumonia (UIP, 63.3% vs 30%). CCVW of irregular size and shape were seen in 19 of 20 SRIF with emphysema and in seven of nine UIP-manifested areas with similar round cysts. A less-involved subpleural parenchyma was observed more frequently in SRIF with emphysema. Conclusion SRIF with emphysema is a more frequent pathological finding than UIP in patients with CCVW on TSCT. The irregular size and shape of CCVW and a less-involved subpleural parenchyma may be a clue suggesting the presence of SRIF with emphysema. PMID:27445472

Can pleural adenosine deaminase (ADA) levels in pleural tuberculosis predict the presence of pulmonary tuberculosis? A CT analysis.

Koh, Myung Je; Lee, In Jae; Kim, Joo-Hee

2016-06-01

To assess the relationship between imaging features of pulmonary tuberculosis at computed tomography (CT) and adenosine deaminase (ADA) values via pleural fluid analysis in patients with pleural tuberculosis. This retrospective study enrolled 60 patients who underwent fluid analysis for ADA and chest CT and were diagnosed with tuberculosis by culture or polymerase chain reaction of pleural fluid and sputum. The presence of centrilobular nodules, consolidation, cavitation, and mediastinal lymphadenopathy at CT were evaluated. The relationship between ADA values and the pattern of pulmonary involvement of tuberculosis was analysed. Pulmonary involvement was seen in 42 of the 60 patients. A centrilobular nodular pattern was seen in 37 and consolidation in 22. In 17 patients, both findings were identified. A centrilobular nodular pattern was more common than consolidation or cavitary lesions. When ADA values were high, pulmonary involvement was more frequent (p=0.002). Comparing low and high ADA groups using an obtained cut-off value of 80 IU/l, the high group had more frequent pulmonary involvement (p<0.001). Patients with tuberculous pleurisy who had high ADA values had a higher probability of manifesting pulmonary tuberculosis. High ADA values may help predict contagious pleuroparenchymal tuberculosis. The most common pulmonary involvement of tuberculous pleurisy showed a centrilobular nodular pattern. Copyright © 2016 The Royal College of Radiologists. Published by Elsevier Ltd.

Evaluation of an alternative methodology for investigating leadership and binge drinking among sorority members.

PubMed

Plucker, Jonathan A; Teed, Carla M

2004-02-01

Recent research suggests that leaders in Greek organizations use alcohol more frequently and more heavily than non-leaders in Greek organizations. These results carry considerable implications for the majority of existing alcohol education programs that rely heavily on peer modeling. The purpose of the present study was to determine whether a more complex and realistic assessment of leadership involvement produced different results than the previous study. Results from 327 women in five randomly selected sororities provide evidence that binge drinking is related to some negative academic outcomes, but that a significant relationship between binge drinking and leadership involvement in Greek organizations does not exist. Furthermore, the results provide evidence that leadership styles do not influence the leadership involvement-binge drinking relationship.

Although millions of men and women in the United States are regularly involved in some form of weightlifting, the average physician knows, and frequently cares, little about the sports involved. As a result, his or her knowledge of the medical and physiological issues involved is limited This article attempts to address this lack by beginning with a brief introductory section outlining some of the similarities differences between the major weight lifting approaches (power lifting, olympic lifting, weight training and body building). Next it reviews major issues and controversies such as age restrictions for lifters, physiological effects, drug use, potential strength gains and hypertrophy. Finally, it discusses some of the more frequent and unique injuries that can occur in lifters.

NPK macronutrients and microRNA homeostasis.

PubMed

Kulcheski, Franceli R; Côrrea, Régis; Gomes, Igor A; de Lima, Júlio C; Margis, Rogerio

2015-01-01

Macronutrients are essential elements for plant growth and development. In natural, non-cultivated systems, the availability of macronutrients is not a limiting factor of growth, due to fast recycling mechanisms. However, their availability might be an issue in modern agricultural practices, since soil has been frequently over exploited. From a crop management perspective, the nitrogen (N), phosphorus (P), and potassium (K) are three important limiting factors and therefore frequently added as fertilizers. NPK are among the nutrients that have been reported to alter post-embryonic root developmental processes and consequently, impairs crop yield. To cope with nutrients scarcity, plants have evolved several mechanisms involved in metabolic, physiological, and developmental adaptations. In this scenario, microRNAs (miRNAs) have emerged as additional key regulators of nutrients uptake and assimilation. Some studies have demonstrated the intrinsic relation between miRNAs and their targets, and how they can modulate plants to deal with the NPK availability. In this review, we focus on miRNAs and their regulation of targets involved in NPK metabolism. In general, NPK starvation is related with miRNAs that are involved in root-architectural changes and uptake activity modulation. We further show that several miRNAs were discovered to be involved in plant-microbe symbiosis during N and P uptake, and in this way we present a global view of some studies that were conducted in the last years. The integration of current knowledge about miRNA-NPK signaling may help future studies to focus in good candidates genes for the development of important tools for plant nutritional breeding.

2018-02-01

Neurofibromatosis type 2 (NF2) is mainly associated with central nervous system (CNS) tumors. Peripheral nerve involvement is described in symptomatic patients, but evidence of subclinical peripheral nerve involvement is scarce. We conducted a cross-sectional pilot study in 2 asymptomatic and 3 minimally symptomatic patients with NF2 to detect subclinical peripheral nerve involvement. Patients underwent clinical examination, nerve conduction studies (NCS), and high-resolution ultrasonography (HRUS). A total of 30 schwannomas were found, divided over 20 nerve segments (33.9% of all investigated nerve segments). All patients had at least 1 schwannoma. Schwannomas were identified with HRUS in 37% of clinically unaffected nerve segments and 50% of nerve segments with normal NCS findings. HRUS shows frequent subclinical peripheral nerve involvement in NF2. Clinicians should consider peripheral nerve involvement as a cause of weakness and sensory loss in the extremities in patients with this disease.

Trust in health Websites: a survey among Norwegian Internet users.

PubMed

Rosenvinge, Jan H; Laugerud, Stein; Hjortdahl, Per

2003-01-01

Whether consumers feel able to trust the information presented on a health-related Website is as important a quality criterion as more objective criteria. We investigated whether trust was related to five aspects of health Websites: the involvement of health professionals, a facility for interactive communication, information about those responsible for the site, a picture of those responsible for the site, and the impression of site update frequency. A polling agency invited, by email, a sample of 600 Norwegian users of e-health information to participate in the study and 476 subjects did so (a 79% response rate), by completing a questionnaire online. Their mean age was 41 years and 53% were female. All five aspects of health Websites were related to the trust placed in the site but they were not consistently related to gender or age. Trust in Websites that were frequently updated was related to being a frequent e-health user, while those who trusted interactive e-health sites were low-frequency users who tended to order drugs and health products from the sites. The probability of taking action as a result of e-health information was related to the frequency of visits to health Websites but not to the five aspects of them investigated in relation to trust. However, respondents who trusted sites that were perceived as being frequently updated and to have health professionals involved were more likely to be frequent users of e-health information.

Neurocysticercosis is the most frequently encountered cerebral parasitic infection worldwide. It is due to infection of the central nervous system by Taenia solium larval form. According to the location of the cysts, parenchymal and extra-parenchymal forms may be identified, with different clinical expressions. We report two cases of neurocysticercosis, one with typical parenchymal involvement and the second with extra-parenchymal involvement revealed by increased intra-cranial pressure. In both cases, the diagnosis was established over 10 years after the onset of symptoms. Neurocysticercosis is very frequent in non-Islamic developing countries, and its incidence is increasing in industrialized nations in relation to tourism and immigration from highly endemic areas. Symptoms usually appear several years after infection and this accounts for the frequent delays before the diagnosis is established.

Drugs Most Frequently Involved in Drug Overdose Deaths: United States, 2010-2014.

PubMed

Warner, Margaret; Trinidad, James P; Bastian, Brigham A; Minino, Arialdi M; Hedegaard, Holly

2016-12-01

Objectives-This report identifies the specific drugs most frequently involved in drug overdose deaths in the United States from 2010 through 2014. Methods-The 2010-2014 National Vital Statistics System mortality files were linked to electronic files containing literal text information from death certificates. Drug overdose was defined using the International Classification of Diseases, Tenth Revision underlying cause-of-death codes X40-X44 (unintentional), X60-X64 (suicide), X85 (homicide), and Y10-Y14 (undetermined intent). Among deaths with an underlying cause of death of drug overdose, the literal text in three fields of the death certificate (i.e., the cause of death from Part I, significant conditions contributing to death from Part II, and a description of how the injury occurred from Box 43) were searched to identify drug mentions. Search term lists were developed using existing drug classification systems as well as from manual review of the literal text. The search term list was then used to identify the specific drugs involved in overdose deaths. Descriptive statistics were reported for drug overdose deaths involving the 10 most frequently mentioned drugs on death certificates. Tables and figures presenting information on the specific drugs involved in deaths are based on deaths with mention of at least one specific drug on the death certificate. Results-From 2010 through 2014, the number of drug overdose deaths per year increased 23%, from 38,329 in 2010 to 47,055 in 2014. During this time period, the percentage of drug overdose deaths involving at least one specific drug increased, from 67% in 2010 to 78% in 2014. Among drug overdose deaths with at least one drug specified on the death certificate, the 10 drugs most frequently involved in overdose deaths included the following opioids: heroin, oxycodone, methadone, morphine, hydrocodone, and fentanyl; the following benzodiazepines: alprazolam and diazepam; and the following stimulants: cocaine and methamphetamine. During this 5-year period, the age-adjusted rate of drug overdose deaths involving heroin more than tripled, and the rate of drug overdose deaths involving methamphetamine more than doubled. The rate of drug overdose deaths involving fentanyl more than doubled in a single year (from 2013 to 2014). In 2014, of the 36,667 drug overdose deaths involving at least one specific drug, 52% of these deaths specified one drug, 38% specified two or three drugs, and 11% specified four or more drugs. Conclusions-Analysis of the literal text from death certificates can be used to identify patterns in the specific drugs most frequently involved in drug overdose deaths. From 2010 through 2014, the top 10 drugs involved were the same, but the relative ranking and age-adjusted rates for deaths involving these drugs changed. Literal text analysis also revealed that many drug overdose deaths involved multiple drugs. Findings should be interpreted in light of the improvement in the quality of the data that resulted from better reporting of specific drugs on death certificates from 2010 through 2014. Relative increases in the death rates involving specific drugs and the rankings of these drugs may be affected by improvements in reporting, real increases in the numbers of death, or both.

The liver is frequently involved by amyloidosis, but hyperbilirubinemia and liver failure are uncommon features. A mild elevation of the serum alkaline phosphatase value and, less frequently, hepatomegaly are the most common findings. Usually the patients have no symptoms related with the liver involvement; the clinical manifestation and the long term prognosis depends on the renal and cardiac disease. We report an unusual clinical presentation of primary amyloidosis in a previously asymptomatic 65 years old woman who was admitted to the hospital because of ictericia and ascitis mimicking a drug induced acute hepatic failure.

The role of leisure and delinquency in frequent cannabis use and dependence trajectories among young adults.

2015-02-01

The link between leisure and cannabis use has been widely studied, but less so for young adults, and rarely with a focus on frequent cannabis use. Also, little is known about how changes in leisure develop over time and how they are related to transitions in cannabis use and dependence. As part of a 3-year longitudinal project, in a qualitative study 47 frequent male and female young adult cannabis users with (n=23) and without (n=24) dependence at baseline were interviewed in-depth after 1.5 and 3 years. Frequent cannabis users (at baseline ≥3 days per week in the past 12 months) are involved in similar leisure activities as the general young adult population and live rather conventional lives, generally away from a delinquent subculture. They mostly regulate their cannabis use to leisure time, to enhance other leisure activities, including socialising and video gaming. While they often give precedence to responsibilities (e.g. work and study), dependent and non-dependent users differed in whether they actively adapted their leisure activities to their cannabis use, or their cannabis use to their leisure time. Both types of and time spent on leisure activities were associated with transitions in use and dependence. While our findings generally support the normalisation thesis, it is questionable whether frequent but non-problematic cannabis use is socially accepted in wider society. This study also questions the diagnostic dependence vs. non-dependence dichotomy, and adds finer distinctions to the concept of cannabis dependence. Implications for prevention and treatment include facilitating structured spending of leisure time (e.g. sports), and targeting frequent users who spent much leisure time video gaming at home.

Female homicide is one of the leading causes of injury deaths in women. In most of such killings, spouses are usually involved because of one or the other reason. The purpose of the study is to identify the risk factors and nature of violence from victimologic point of view in female homicide. Information was obtained by interviewing the accompanying persons, postmortem examination and perusal of hospital records. There were 39 female victims of total 162 homicide. The peak age of the female homicide victim was 3rd decade. The victims were most frequently killed by their spouses. Argument (33.3%) and dowry (30.7%) were the most frequent reasons behind the crime. Majority of victims (84.6%) were killed in their home. Fatal wound is most frequently seen in head and defense wound is present only in nine cases. Considering sociological aspect of victim, 82% of the victims were from Hindu religion, majorities of them were married, illiterate, and drawn from low-socioeconomic status and rural community.

Wong, Li Ping; Awang, Halimah; Jani, Rohana

2012-01-01

In the present study, researchers explored attitudes toward midlife crises, experience with midlife crises, help-seeking, and needs among multi-ethnic Malaysian women. A total of 14 focus group discussions were conducted with 89 Malaysian women of different ages and socioeconomic backgrounds. Women expressed concern over physical aging and decline in their physical functional health. Having a midlife crisis was frequently reported. Issues that were frequently reported to trigger a midlife crisis, such as empty nest syndrome, impact of aging on sexual and reproductive function, extended parenthood, caring for aging or ill parents, and career challenges were noted by the study participants (listed here in order of most to least frequently reporting of these themes across the group discussions). Overall, these issues were associated with attitudes about aging. A comparatively less open attitude toward sexual attitudes and help-seeking for sexual problems were found among the Malay and Indian women. This may imply that intervention to increase positive attitudes concerning both sexuality and help-seeking intentions should be culturally specific. The use of religious coping for comfort and consolation was frequently reported; therefore, those providing midlife crisis prevention and intervention programs should consider involving faith-based interventions in the Malaysian setting.

The objective of this study was to describe the factors involved in biological exposure-related injuries occurring in worker from a health system in Galicia, Spain. The study was conducted in a health system of the Health Service of Galicia, that included four hospitals and 72 primary care centers, with nearly 6000 workers. The study used occupational injury data available o in the injury registry of the Health Service of Galicia for the year 2011. We identified 194 biohazard-related injuries. Exposures, locations, devices, tasks and causes of these incidents were analysed. The majority of biological exposures occurred through needlestick injuries (82%). The areas where more injuries occurred were in inpatient wards (37%) and operating rooms (25%). The devices most frequently involved were suture needles (15%) and insulin needles (15%). The most frequently recorded causes were lack of training and information, together with lack of biosafety devices. Worker training and information should be promoted along with the implementation of biosafety devices, as the latter measure alone does not seem sufficient to reduce the number of injuries.

Transmission of zoonotic pathogens from bats to humans through direct and indirect contact with bats raises public apprehension about living close to bats. In the township of Ve Golokuati in Ghana, several “camps” of Epomophorus gambianus roost in fruit trees that provide ecosystems services for residents. This study explored human-bat interaction in the township and the potential risks of disease transmission from bats to humans. Data were derived through questionnaire administration and participatory appraisal approach involving focus group discussions, participatory landscape mapping, and transect walk. The study found that most human activities within the township, such as petty-trading, domestic chores, and children's outdoor recreation, exposed people to bats. Though there have been no reported cases of disease spillover from bats to humans from the perspective of residents and from medical records, respondents whose activities brought them closer to bats within the township were found to be more likely to experience fevers than those who do not interact with bats frequently. The study recommends education of community members about the potential risks involved in human-bat interactions and makes suggestions for reducing the frequent interactions with and exposure to bats by humans.

These studies investigate connections between magazine reading and involvement and young people's sexual health knowledge, self-efficacy, intentions, and contraception use. Study 1 assessed sexual health behaviors and magazine reading among 579 undergraduate students (69% were female; 68% were White; M(age) = 19.73). As expected, more frequent reading of mainstream magazines was associated with greater sexual health knowledge, safe-sex self-efficacy, and consistency of using contraception, although results varied across sex and magazine genre. Study 2 replicated and expanded on these findings with a survey of 422 undergraduate students (51% were female; 71% were White; 49% were age 18 or younger), incorporating a more extensive knowledge scale, questions about safe-sex intentions, and measures of magazine involvement. Results suggest that magazine use is associated with positive sexual health outcomes among young people.

Leptospirosis is a zoonotic disease, which has become a major public health threat in Sri Lanka. A majority of patients are farmers in rural endemic areas. The purpose of the present study is to describe the level of knowledge and frequencies of risky practices related to leptospirosis among a sample of rural school adolescents in Galgamuwa, Kurunegala district, a highly endemic area in Sri Lanka. A descriptive cross-sectional study was conducted among 460 adolescents studying in grades 9 and 10 of government schools. Study participants were selected using a multistage cluster sampling technique. A structured, pretested, self-administered questionnaire was used to collect data on sociodemographic characteristics, knowledge on leptospirosis, and frequency of associated risky practices related to leptospirosis. The response rate was 100%. Fifty-two percent of respondents had a 'good' level of knowledge of leptospirosis. In the assessment of practices, 62% were involved in rice paddy cultivation either 'frequently' or 'rarely'. Seventy percent of the fathers and 50% of the mothers of the students were involved in paddy cultivation. Thirteen percent reported that they swam, bathed, or washed in ponds of stagnant water. Of the students involved in paddy cultivation, only 18% said they usually used gloves and boots 'frequently'. Among the 9% of students who handled cattle or buffalo, 61% reported washing their hands and feet after handling the animals. Good level of knowledge was significantly associated with involvement in paddy cultivation among the adolescents (p=0.45), fathers (p<0.001), and mothers (p=0.012). The level of knowledge was not significantly associated with practicing preventive measures for leptospirosis. Although the respondent's overall level of knowledge regarding leptospirosis was satisfactory, the study identified several important gaps in specific areas. Those who were involved or had parents involved in paddy cultivation had better knowledge. However, this knowledge was not translated into practice of personal preventive measures. Use of protective attire in paddy farming needs to be facilitated by health authorities.

Determining the genetic basis of cancer requires comprehensive analyses of large collections of histopathologically well-classified primary tumours. Here we report the results of a collaborative study to discover somatic mutations in 188 human lung adenocarcinomas. DNA sequencing of 623 genes with known or potential relationships to cancer revealed more than 1,000 somatic mutations across the samples. Our analysis identified 26 genes that are mutated at significantly high frequencies and thus are probably involved in carcinogenesis. The frequently mutated genes include tyrosine kinases, among them the EGFR homologue ERBB4; multiple ephrin receptor genes, notably EPHA3; vascular endothelial growth factor receptor KDR; and NTRK genes. These data provide evidence of somatic mutations in primary lung adenocarcinoma for several tumour suppressor genes involved in other cancers—including NF1, APC, RB1 and ATM—and for sequence changes in PTPRD as well as the frequently deleted gene LRP1B. The observed mutational profiles correlate with clinical features, smoking status and DNA repair defects. These results are reinforced by data integration including single nucleotide polymorphism array and gene expression array. Our findings shed further light on several important signalling pathways involved in lung adenocarcinoma, and suggest new molecular targets for treatment. PMID:18948947

Mammals exhibit marked morphological differences in the muscles surrounding the jaw bone due to differences in eating habits. Furthermore, the myofiber properties of the muscles differ with function. Since the muscles in the oral region have various functions such as eating, swallowing, and speech, it is believed that the functional role of each muscle differs. Therefore, to clarify the functional role of each masticatory muscle, the myofiber properties of the adult mouse masticatory muscles were investigated at the transcriptional level. Expression of MyHC-2b with a fast contraction rate and strong force was frequently noted in the temporal and masseter muscles. This suggests that the temporal and masseter muscles are closely involved in rapid antero-posterior masticatory movement, which is characteristic in mice. Furthermore, expression of MyHC-1 with a low contraction rate and weak continuous force was frequently detected in the lateral pterygoid muscle. This suggests that, in contrast to other masticatory muscles, mouse lateral pterygoid muscle is not involved in fast masticatory movement, but is involved in functions requiring continuous force such as retention of jaw position. This study revealed that muscles with different roles function comprehensively during complicated masticatory movement.

Hallucinations have been described in various clinical populations, but they are neither disorder nor disease specific. In schizophrenia patients, hallucinations are hallmark symptoms and auditory ones are described as the more frequent. In Parkinson's disease, the descriptions of hallucination modalities are sparse, but the hallucinations do tend to have less negative consequences. Our study aims to explore the phenomenology of hallucinations in both hallucinating schizophrenia patients and Parkinson's disease patients using the Psycho-Sensory hAllucinations Scale (PSAS). The main objective is to describe the phenomena of these clinical symptoms in those two specific populations. Each hallucinatory sensory modality significantly differed between Parkinson's disease and schizophrenia patients. Auditory, olfactory/gustatory and cœnesthetic hallucinations were more frequent in schizophrenia than visual hallucinations. The guardian angel item, usually not explored in schizophrenia, was described by 46% of these patients. The combination of auditory and visual hallucinations was the most frequent for both Parkinson's disease and schizophrenia. The repercussion index summing characteristics of each hallucination (frequency, duration, negative aspects, conviction, impact, control and sound intensity) was always higher for schizophrenia. A broader view including widespread characteristics and interdisciplinary works must be encouraged to better understand the complexity of the process involved in hallucinations.

Scott, Lisa Benz

2008-01-01

Purpose: Physical therapists have engaged in cardiac rehabilitation (CR) and pulmonary rehabilitation (PR) for decades, but the extent of their current involvement in this practice area is unclear. This study surveyed directors of CR and PR programs on a statewide level to ascertain what type of provider is writing the prescription, which methods of exercise formulation are used, which outcome measures are used and their congruency with established guidelines. Methods: A convenience sample of outpatient CR and PR directors (n=31) representing 38 CR and/or PR programs located in New York completed a survey in spring 2005 (29 CR and 9 PR). Results: Results showed that only 2 physical therapists were responsible for writing exercise prescriptions in CR and PR programs. Most program directors were registered nurses (53%), who also wrote the majority of CR exercise prescriptions. Exercise intensity was most frequently determined using formulae and data that were highly patient-specific. Clinical outcomes most frequently included Quality of Life scales and stress tests. Conclusions: Physical therapists are minimally involved in directing programs and writing exercise prescriptions. Exercise prescriptions are individualized to the patient. Outcome measures most frequently used by participating CR and PR program directors are consistent with nationally-recognized best practice. PMID:20467497

Capturing Parents' Individual and Institutional Interest Toward Involvement in Science Education

NASA Astrophysics Data System (ADS)

Kaya, Sibel; Lundeen, Cynthia

2010-11-01

Parents are generally less involved in their children’s science education (as compared to reading and mathematics) due to low self-efficacy and a lack of home-school communication. This study examined parental interest and attitudes in science as well as the nature of parent-to-child questioning during an interactive home, school, and community collaboration in the southeastern United States. Study results, compiled from observations, exit surveys, and interviews revealed largely positive family interactions and attitudes about science learning and increased parental interest toward involvement in elementary science. Parents frequently used productive questioning techniques during activities. These results imply that successful home, school, and community partnerships may elevate levels of parental participation in their children’s science education and the parents’ perception of themselves as being competent in assisting in science.

This study aimed to explore the service needs and preferences of frequent emergency department users with mental health and addictions concerns who participated in a brief intensive case management intervention. We conducted semi-structured individual interviews with 20 frequent emergency department users with mental health and addictions challenges, 13 service providers involved in the delivery of a brief case management intervention, and a focus group with intervention case managers. Thematic analysis was used to explore perceived service user profiles, service needs and preferences of care. Service users experienced complex health and social needs and social isolation, while exhibiting resilience and the desire to contribute. They described multiple instances of stigmatization in interactions with healthcare professionals. Components of the brief intensive case management intervention perceived to be helpful included system navigation, advocacy, intermediation, and practical needs assistance. Frequent service users valued relational responsiveness, a non-judgmental stance, and a recovery orientation in case managers. Interventions for frequent service users in mental health may be enhanced by focusing on the engagement of formal and informal social supports, practical needs assistance, system navigation, advocacy and intermediation, and attention to the recovery goals of service users.

Parent-teen communication and pre-college alcohol involvement: a latent class analysis.

2011-12-01

Although parent-adolescent communication has been identified as important in delaying the onset and escalation of alcohol use, both the strength and direction of observed associations have varied in prior research with adolescents and college students. The current study categorizes parents according to alcohol-related communication and relates these categories to other parenting factors and late adolescent alcohol involvement. As part of a larger study, 1007 college-bound teens and their parents were assessed. Teens were asked to report on their drinking behavior, and parents were asked about the occurrence of several specific alcohol-related communications with their teen, as well as additional parenting characteristics. Profiles of parent alcohol-related communication were derived using latent class analysis. Once the best fitting solution was determined, covariates were entered predicting class membership and investigating how classes were associated with additional parenting characteristics and teen alcohol use. A five-class solution provided the best fit to the data: Frequent, All Topics (28%); Moderate, All Topics (25%); Frequent, General Topics (25%); Frequent, Consequences and Limits (12%); and Infrequent, All Topics (10%). Covariate analyses demonstrated class differences with regard to parental modeling, monitoring, knowledge, and parent-teen relationship satisfaction, as well as for students' intentions to join fraternities/sororities and alcohol use. Findings from the current study add to a small but growing literature supporting the continuing influence of parents in late adolescence and suggest that the frequency and specificity of parent-teen communication are potentially informative for refined parent-based preventive interventions.

The aim of this study is to describe the epidemiological, clinical characteristics, and outcome of patients with left-side endocarditis caused by gram-negative bacteria. Prospective multicenter study of left-sided infective endocarditis reported in the Andalusian Cohort for the Study of Cardiovascular Infections between 1984 and 2008. Among the 961 endocarditis, 24 (2.5%) were caused by gram-negative bacilli. The most common pathogens were Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica. Native valves (85.7%) were mainly affected, most of them with previous valve damage (57%). Comorbidity was greater (90% vs 39%; P=.05) than in endocarditis due to other microorganism, the most frequent being, diabetes, hepatic cirrhosis and neoplasm. A previous manipulation was found in 47.6% of the cases, and 37% were considered hospital-acquired. Renal failure (41%), central nervous system involvement (33%) and ventricular dysfunction (45%) were the most frequent complications. Five cases (21%) required cardiac surgery, mostly due to ventricular dysfunction. More than 50% of cases were treated with aminoglycosides, but this did not lead to a better outcome or prognosis. Mortality (10 patients) was higher than that reported with other microorganisms (41% vs 35%; P=.05). Left-sided endocarditis due to gram-negative bacilli is a rare disease, which affects patients with major morbidities and often with a previous history of hospital manipulations. Cardiac, neurological and renal complications are frequent and associated with a high mortality. The association of aminoglycosides in the antimicrobial treatment did not involve a better outcome or prognosis. Copyright © 2010 Elsevier España, S.L. All rights reserved.

Spinocerebellar ataxias (SCAs) are characterized by autosomal dominantly inherited progressive ataxia but are clinically heterogeneous due to variable involvement of non-cerebellar parts of the nervous system. Non-cerebellar symptoms contribute significantly to the burden of SCAs, may guide the clinician to the underlying genetic subtype, and might be useful markers to monitor disease. Peripheral neuropathy is frequently observed in SCA, but subtype-specific features and subclinical manifestations have rarely been evaluated. We performed a multicenter nerve conduction study with 162 patients with genetically confirmed SCA1, SCA2, SCA3, and SCA6. The study proved peripheral nerves to be involved in the neurodegenerative process in 82 % of SCA1, 63 % of SCA2, 55 % of SCA3, and 22 % of SCA6 patients. Most patients of all subtypes revealed affection of both sensory and motor fibers. Neuropathy was most frequently of mixed type with axonal and demyelinating characteristics in all SCA subtypes. However, nerve conduction velocities of SCA1 patients were slower compared to other genotypes. SCA6 patients revealed less axonal damage than patients with other subtypes. No influence of CAG repeat length or biometric determinants on peripheral neuropathy could be identified in SCA1, SCA3, and SCA6. In SCA2, earlier onset and more severe ataxia were associated with peripheral neuropathy. We proved peripheral neuropathy to be a frequent site of the neurodegenerative process in all common SCA subtypes. Since damage to peripheral nerves is readily assessable by electrophysiological means, nerve conduction studies should be performed in a longitudinal approach to assess these parameters as potential progression markers.

Background Patients in the Neonatal Intensive Care Unit (NICU) are at an increased risk for medication errors. Objective The objective of this study is to describe the nature and setting of medication errors occurring in patients admitted to an NICU in Qatar based on a standard electronic system reported by pharmacists. Setting Neonatal intensive care unit, Doha, Qatar. Method This was a retrospective cross-sectional study on medication errors reported electronically by pharmacists in the NICU between January 1, 2014 and April 30, 2015. Main outcome measure Data collected included patient information, and incident details including error category, medications involved, and follow-up completed. Results A total of 201 NICU pharmacists-reported medication errors were submitted during the study period. All reported errors did not reach the patient and did not cause harm. Of the errors reported, 98.5% occurred in the prescribing phase of the medication process with 58.7% being due to calculation errors. Overall, 53 different medications were documented in error reports with the anti-infective agents being the most frequently cited. The majority of incidents indicated that the primary prescriber was contacted and the error was resolved before reaching the next phase of the medication process. Conclusion Medication errors reported by pharmacists occur most frequently in the prescribing phase of the medication process. Our data suggest that error reporting systems need to be specific to the population involved. Special attention should be paid to frequently used medications in the NICU as these were responsible for the greatest numbers of medication errors.

2012-01-01

Localized scleroderma is a rare disease, characterized by sclerotic lesions. A variety of presentations have been described, with different clinical characteristics and specific prognosis. In scleroderma en coup de sabre (LScs) the atrophic lesion in frontoparietal area is the disease hallmark. Skin and subcutaneous are the mainly affected tissues, but case reports of muscle, cartilage, and bone involvement are frequent. These cases pose a difficult differential diagnosis with Parry-Romberg syndrome. Once considered an exclusive cutaneous disorder, the neurologic involvement present in LScs has been described in several case reports. Seizures are most frequently observed, but focal neurologic deficits, movement disorders, trigeminal neuralgia, and mimics of hemiplegic migraines have been reported. Computed tomography and magnetic resonance imaging have aided the characterization of central nervous system lesions, and cerebral angiograms have pointed to vasculitis as a part of disease pathogenesis. In this paper we describe the clinical and radiologic aspects of neurologic involvement in LScs. PMID:22319646

Mental health nurses have a key role in improving the physical health of people with a serious mental illness, however, there have been few studies of their attitudes or the extent of their involvement in this work. The aim of this study was to examine mental health nurses' attitudes to physical health care and explore associations with their practice and training. A postal questionnaire survey including the Physical Health Attitude Scale for mental health nurses (PHASe) was used within a UK mental health trust. The 52% (n = 585) of staff who responded reported varying levels of physical health practice; this most frequently involved providing dietary and exercise advice and less frequently included advice regarding cancer screening and smoking cessation. Having received post-registration physical health-care training and working in inpatient settings was associated with greater reported involvement. More positive attitudes were also evident for nurses who had attended post-registration physical health training or had an additional adult/general nursing qualification. Overall, the attitudes of mental health nurses towards physical health care appear positive and the willingness of nurses to take on these roles needs to be recognized. However, there are areas where nurses in our sample were more ambivalent such as cancer screening and smoking cessation. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

Peripheral neuropathy in mitochondrial diseases (MDs) may vary from a subclinical finding in a multisystem syndrome to a severe, even isolated, manifestation in some patients. To investigate the involvement of the peripheral nervous system in MDs extensive electrophysiological studies were performed in 109 patients with morphological, biochemical and genetic diagnosis of MD [12 A3243G progressive external ophthalmoplegia (PEO)/mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS), 16 myoclonic epilepsy with ragged-red fibres (MERRF), four mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), 67 PEO with single or multiple deletions of mitochondrial DNA, 10 others]. A neuropathy was found in 49 patients (45%). The incidence was very high in MNGIE (100%), MELAS (92%) and MERRF (69%), whilst 28% of PEO patients had evidence of peripheral involvement. The most frequent abnormality was a sensory axonal neuropathy found in 32/49 patients (65%). A sensory-motor axonal neuropathy was instead detected in 16% of the patients and sensory-motor axonal demyelinating neuropathy in 16%. Finally one Leigh patient had a motor axonal neuropathy. It is interesting to note that the great majority had preserved tendon reflexes and no sensory disturbances. In conclusion, peripheral involvement in MD is frequent even if often mild or asymptomatic. The correct identification and characterization of peripheral neuropathy through electrophysiological studies represents another tile in the challenge of MD diagnosis. © 2016 EAN.

Facioscapulohumeral muscular dystrophy (FSHD) presents with 2 genetically distinct types. We describe for the first time the MRI patterns of leg muscle involvement in type 2 and compare it with type 1. The intramuscular fat content was assessed on lower extremity axial T1-weighted MRI scans in 6 FSHD1 and 5 FSHD2 patients. Overall, the muscle involvement profile did not differ substantially between FSHD1 and FSHD2. In the thigh, the dorsomedial compartment including the semimembranosus, semitendinosus and adductor magnus was the most affected. The quadriceps was mostly spared, but isolated involvement of the rectus femoris was common. Fat infiltration in the distal soleus and the medial gastrocnemius with sparing of the lateral gastrocnemius was a common finding; involvement of the tibialis anterior was less frequent. A proximal-to-distal increase in fat content was frequently present in some muscles. Muscle involvement appears to be independent of type, confirming a similar pathophysiological pathway in FSHD1 and FSHD2. © 2016 S. Karger AG, Basel.

This study investigated the process involved in the lateralization of movements during infancy by observing upper extremity movements in a laboratory setting. Reaching for flying rings, balls, mini toy cars, and small round cookies were observed and recorded by videotape at 4 and 9 months of age. The subjects were 202 infants who participated in Japan Children's Study, a cohort study on the development of sociability. Infants reached for objects significantly more frequently at 9 months (98%) than at 4 months (40%) (p<0.001). Though the lateral preference in reaching for balls at 4 months was ambiguous, reaching for toy cars was performed more frequently with the right hand at 9 months (50%) than with the left one (19%) (p<0.01). Lateralization of the upper extremity movements is thought to appear by 9 months.

To determine the most frequent food allergens causing immediate hypersensitivity reactions in Swiss children of different age groups and to investigate the clinical manifestation of IgE-mediated food allergies in young patients. The study was a prospective analysis of children referred for assessment of immediate type I food hypersensitivity reactions. The diagnostic strategy included a careful history, skin prick tests with commercial extracts and native foods, in vitro determination of specific IgE to food proteins and food challenges when appropriate. A total of 278 food allergies were identified in 151 children with a median age of 1.9 years at diagnosis. Overall, the most frequent food allergens were hen's egg (23.7%), cow's milk (20.1%), peanut (14.0%), hazelnut (10.4%), wheat (6.1%), fish (4.3%), kiwi and soy (2.2% each). In infancy, cow's milk, hen's egg and wheat were the most common allergens. In the second and third year of life however, the top three food allergens were hen's egg, cow's milk and peanut, whereas above the age of 3 years, peanut was number one, followed by hen's egg and fish. Overall, urticaria (59.0%) and angioedema (30.2%) were the most frequent clinical manifestations. Gastrointestinal symptoms were found in 25.9% and respiratory involvement in 25.2%. There were 13 cases (4.7%) of anaphylaxis to peanut, fish, cow's milk, hen's egg, wheat and shrimps. A total of eight allergens account for 83% of IgE-mediated food allergies in Swiss infants and children, with differences in the distribution and order of the most frequently involved food allergens between paediatric age groups.

Abstract We designed a retrospective cohort study to assess sex-related differences in clinical manifestations, incidence, and outcomes of patients with symptomatic acute aortic dissection (AAD). We collected clinical data from 2010 to 2015 of 400 patients with AAD. Patients’ clinical characteristics, treatment, and outcomes were analyzed as a function of sex. Among 400 patients with AAD, the ratio of men to women was 3.18:1; the incidence of atherosclerosis was higher in women (P = 0.02). Dysphoria (P = 0.01), focal neurological deficits (P = 0.04), and pulse deficits (P = 0.03) were more frequent in men. Imaging findings revealed that pleural effusion (P < 0.01), celiac trunk involvement (P < 0.01), and superior mesenteric artery involvement (P = 0.02) were more frequent in men. Dissection-related pneumonia (P = 0.02), pulmonary atelectasis (P = 0.01), aortic intramural hematoma (P < 0.01), ischemic electrocardiographic changes (P = 0.03), and in-hospital complications such as myocardial ischemia (P = 0.03), hypoxemia (P < 0.01), cardiac tamponade (P = 0.01) occurred more frequently in women. Women with type A dissection had higher in-hospital mortality than men (P < 0.01). The presentation of AAD varies with a patient's sex. Women with AAD had clinical features different from men as follows: higher age of onset, more frequent inpatient complications, and higher in-hospital mortality. These findings may lead to a better understanding of aortic dissection in women that will improve their outcomes. PMID:26986151

Vincristine (VCR) induced peripheral neuropathy is a common complication in children with acute lymphoblastic leukemia (ALL). A retrospective data analysis over an interval of 10 years (2006-2016) of all children with ALL seen at Sultan Qaboos University Hospital was carried out. Electronic medical records of eligible patients were reviewed. Patients with clinical evidence of neuropathy and abnormal nerve conduction studies (NCSs) were included in the study. Nineteen (nine females and 10 males) out of 103 pediatric patients developed VCR-related neuropathy, and their age ranged between 2.5 and 14 years. Symptoms started after 2-11 doses of VCR. All 19 patients had documented peripheral neuropathy on NCSs. The autonomic nervous system and cranial nerves affection was relatively common in our patients; two presented with bradycardia, two patients with unexplained tachycardia, and five had abdominal pain and constipation, complicated by typhlitis in two patients. One patient developed unilateral hearing loss. Two patients developed severe life-threatening cranial nerve involvement with bilateral ptosis and recurrent laryngeal nerve involvement presented as vocal cord paralysis, hoarseness of voice, frequent chocking, and aspiration episodes. Peripheral neuropathy was the commonest form of VCR-related neuropathy. Autonomic neuropathy was relatively common in our patients. Cranial neuropathy is a serious side effect of VCR that can be severe, involving multiple cranial nerves and needs prompt recognition and management. Concomitant administration of pyridoxine and pyridostigmine does not seem to protect against further neurological damage in some patients. © 2017 Wiley Periodicals, Inc.

Opioids are important medications for pain and opioid maintenance treatment. Increasing use and abuse of prescription opioids has, however, caused worldwide concern. Our aim was to estimate the ratio between prescription opioid abuse and total use, based on representative postmortem toxicology. Our material included all the medico-legally examined deaths in Finland during 2010-2011 involving positive findings involving buprenorphine, codeine, fentanyl, methadone, oxycodone, or tramadol. We studied drug abuse by age group, with "abuse" meaning licit opioids used illicitly as narcotics. Drug-abuse history, drug injecting, or laboratory findings of illicit drugs defined an abuser case. We then compared abuser cases and other opioid-related cases between the opioids with the number of fatal poisonings, accidents, suicides, alcohol findings, concomitant opioid use, and median postmortem blood opioid concentrations. Opioid findings numbered 2499 in 2088 cases. Drug abuse involved 545 opioid-positive cases, which in Finland represented 0.5% of those deceased. The proportion of abuser cases among all opioid-related cases for buprenorphine was 85.5%, for methadone 82.4%, for tramadol 29.4%, for codeine 16.3%, for fentanyl 14.5%, and for oxycodone 6.9%. Abuse in age-groups >60 was rare. Concomitant other opioid findings were more frequent in abuser- than in other cases for codeine, oxycodone, and tramadol, whereas alcohol findings were more frequent in buprenorphine, codeine, and fentanyl abuse. Buprenorphine and methadone were most often related to drug abuse. Every other opioid studied involved some abuse, and especially tramadol. Abuse and fatal poisonings were concentrated in men aged 20-49. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Involving users/carers in mental health care-planning is central to international policy initiatives yet users frequently report feeling excluded from the care planning process. Rigorous explorations of mental health professionals' experiences of care planning are lacking, limiting our understanding of this important translational gap. To explore professional perceptions of delivering collaborative mental health care-planning and involving service users and carers in their care. Qualitative interviews and focus groups with data combined and subjected to framework analysis. UK secondary care mental health services. 51 multi-disciplinary professionals involved in care planning and recruited via study advertisements. Emergent themes identified care-planning as a meaningful platform for user/carer involvement but revealed philosophical tensions between user involvement and professional accountability. Professionals emphasised their individual, relational skills as a core facilitator of involvement, highlighting some important deficiencies in conventional staff training programmes. Although internationally accepted on philosophical grounds, user-involved care-planning is poorly defined and lacks effective implementation support. Its full realisation demands greater recognition of both the historical and contemporary contexts in which statutory mental healthcare occurs. Copyright © 2015 The Authors.

Numerous quantitative studies have examined the association between family meal frequency and child/adolescent weight and weight-related behaviors. However, limited qualitative research has been conducted to identify mealtime characteristics (e.g., child behavior during meals, rules/expectations, family dynamics) that occur during family meals that may explain why some families engage in frequent family meals and others do not. This is particularly important within racially/ethnically diverse households, as these demographic groups are at higher risk for weight-related problems. The current study aimed to identify similarities and differences in mealtime characteristics between households that have frequent and infrequent family meals within a low-income and minority population. This qualitative study included 118 parents who participated in Family Meals, LIVE!, a mixed-methods, cross-sectional study. Parents (90% female; mean age = 35) were racially/ethnically diverse (62% African American, 19% White, 4% Native American, 4% Asian, 11% Mixed/Other) and from low-income (73% < $35,000/yr.) households. Data were analyzed using inductive content analysis. Results indicated some similar mealtime characteristics (i.e., picky eating, involving family members in meal preparation) between households having frequent and infrequent family meals. Additionally, several differences in mealtime characteristics were identified between households having frequent (i.e., importance of family meals, flexibility in the definition of family meals, family meal rules, no pressure-to-eat feeding practices) versus infrequent family meals (i.e., pressure-to-eat parent feeding practices, family meals are dinner meals only, and difficult meal time behaviors). Study findings may be useful for developing intervention targets for low-income and racially/ethnically diverse households so more families can benefit from the protective nature of family meals.

Relationship of parasites and pathologies to contaminant body burden in sentinel bivalves: NOAA Status and Trends 'Mussel Watch' Program.

PubMed

Kim, Yungkul; Powell, Eric N; Wade, Terry L; Presley, Bobby J

2008-03-01

The 1995-1998 database from NOAA's National Status and Trends 'Mussel Watch' Program was used to compare the distributional patterns of parasites and pathologies with contaminant body burdens. Principal components analysis (PCA) resolved five groups of contaminants in both mussels and oysters: one dominated by polycyclic aromatic hydrocarbons (PAHs), one dominated by pesticides, and three dominated by metals. Metals produced a much more complex picture of spatial trends in body burden than did either the pesticides or PAHs. Contrasted to the relative simplicity of the contaminant groupings, PCA exposed a suite of parasite/pathology groups with few similarities between the sentinel bivalve taxa. Thus, the relationship between parasites/pathologies and contaminants differs significantly between taxa despite the similarity in contaminant pattern. Moreover, the combined effects of many contaminants and parasites may be important, leading to complex biological-contaminant interactions with synergies both of biological and chemical origin. Overall, correlations between parasites/pathologies and contaminants were more frequent with metals, frequent with pesticides, and less frequent with PAHs in mussels. In oysters, correlations with pesticides and metals were about equally frequent, but correlations with PAHs were still rare. In mytilids, correlations with metals predominated. Negative and positive correlations with metals occurred with about the same frequency in both taxa. The majority of correlations with pesticides were negative in oysters; not so for mytilids. Of the many significant correlations involving parasites, few involved single-celled eukaryotes or prokaryotes. The vast majority involved multi-cellular eukaryotes and nearly all of them either cestodes, trematode sporocysts, or trematode metacercariae. The few correlations for single-celled parasites all involved proliferating protozoa or protozoa reaching high body burdens through transmission. The tendency for the larger or more numerous parasites to be involved suggests that unequal sequestration of contaminates between host and parasite tissue is a potential mediator. An alternative is that contaminants differentially affect parasites and their hosts by varying host susceptibility or parasite survival.

The correlates of left ventricular (LV) substrate in arrhythmogenic right ventricular (RV) cardiomyopathy are largely unknown. Thirty-two patients with arrhythmogenic RV cardiomyopathy (47±14 years; 6 women) were included. RV and LV dysplasia were defined from multidetector computed tomography and cardiac magnetic resonance imaging. Arrhythmias were characterized as right-sided or left-sided on 12-lead ECG recordings at baseline and during isoproterenol testing. In 14 patients, the imaging substrate was compared with voltage mapping and local abnormal ventricular activity. Imaging abnormalities were found in 32 (100%) and 21 (66%) patients on the RV and LV, respectively, intramyocardial fat on multidetector computed tomography being the most sensitive feature. LV involvement related to none of the Task Force criteria. Right-sided arrhythmias were more frequent than left-sided arrhythmias (P=0.003) although the latter were more frequent in case of LV involvement (P=0.02). The agreement between low voltage and fat on multidetector computed tomography was high on the RV when using either endocardial unipolar or epicardial bipolar data (κ=0.82 and κ=0.78, respectively) but lower on the LV (κ=0.54 for epicardial bipolar). LV local abnormal ventricular activity was found in all patients with LV involvement, and none of the others. The density of local abnormal ventricular activity within fat areas was similar between the RV and LV (P=0.57). LV substrate is frequent in arrhythmogenic RV cardiomyopathy, but poorly identified by current diagnostic strategies. Left-sided arrhythmias are more frequent in case of LV involvement. LV fat hosts the same density of local abnormal ventricular activity as RV fat, but is less efficiently detected by voltage mapping. These results support the need for alternative diagnostic strategies to identify LV dysplasia. © 2015 American Heart Association, Inc.

Religious Involvement and Marijuana Use for Medical and Recreational Purposes

2018-01-01

In this article, we use data from the 2016 National Survey on Drug Use and Health (NSDUH) to examine the association between religious involvement and marijuana use for medical and recreational purposes in U.S. adults (N = 41,517). We also consider whether the association between religious involvement and marijuana use varies according to personal health status. Our results show that adults who attend religious services more frequently and hold more salient religious beliefs tend to exhibit lower rates of medical and recreational marijuana use. We also find that these “protective effects” are less pronounced for adults in poor health. Although our findings confirm previous studies of recreational marijuana use, we are the first to examine the association between religious involvement and medical marijuana use. Our moderation analyses suggest that the morality and social control functions of religious involvement may be offset under the conditions of poor health. PMID:29899577

Voxelwise distribution of acute ischemic stroke lesions in patients with newly diagnosed atrial fibrillation: Trigger of arrhythmia or only target of embolism?

Objective Atrial fibrillation (AF) is frequently detected after ischemic stroke for the first time, and brain regions involved in autonomic control have been suspected to trigger AF. We examined whether specific brain regions are associated with newly detected AF after ischemic stroke. Methods Patients with acute cerebral infarctions on diffusion-weighted magnetic resonance imaging were included in this lesion mapping study. Lesions were mapped and modeled voxelwise using Bayesian Spatial Generalised Linear Mixed Modeling to determine differences in infarct locations between stroke patients with new AF, without AF and with AF already known before the stroke. Results 582 patients were included (median age 68 years; 63.2% male). AF was present in 109/582 patients [(18.7%); new AF: 39/109 (35.8%), known AF: 70/109 (64.2%)]. AF patients had larger infarct volumes than patients without AF (mean: 29.7 ± 45.8 ml vs. 15.2 ± 35.1 ml; p<0.001). Lesions in AF patients accumulated in the right central middle cerebral artery territory. Increasing stroke size predicted progressive cortical but not pontine and thalamic involvement. Patients with new AF had more frequently lesions in the right insula compared to patients without AF when stroke size was not accounted for, but no specific brain region was more frequently involved after adjustment for infarct volume. Controlled for stroke size, left parietal involvement was less likely for patients with new AF than for those without AF or with known AF. Conclusions In the search for brain areas potentially triggering cardiac arrhythmias infarct size should be accounted for. After controlling for infarct size, there is currently no evidence that ischemic stroke lesions of specific brain areas are associated with new AF compared to patients without AF. This challenges the neurogenic hypothesis of AF according to which a relevant proportion of new AF is triggered by ischemic brain lesions of particular locations. PMID:28542605

PURPOSE OF THE STUDY Thoracic trauma, one of the most frequent injuries in patients with multiple traumata, is found in 50 to 80% of these patients and it is crucial for the patient's prognosis. It accounts for 25% of all death from polytraumatic injuries. The aim of this retrospective study was an analysis of the occurrence of chest injuries in polytrauma patients and their surgical treatment in the Trauma Centre or Department of Surgery of the University Hospital Pilsen in a five-year period. MATERIAL AND METHODS Patients with injuries meeting the definition of polytrauma and an Injury Severity Score (ISS) ≥16 were included. The demographic characteristics, mechanism of multiple trauma, ISS value and chest injury were recorded in each patient. The number of injured patients in each year of the study was noted. In the patients with chest injury, the type of injury and method of treatment were assessed. The therapy was further analysed including its timing. The number of deaths due to polytrauma involving chest injury, the cause of death and its time in relation to the patient's admission to the Trauma Centre were evaluated. RESULTS In the period 2010-14, 513 polytrauma patients were treated; of them 371 (72.3%) were men with an average age of 40.5 years. The most frequent cause of injury was a traffic accident (74%). The average ISS of the whole group was 35 points. Chest injury was diagnosed in 469 patients (91.4%) of whom only five (1.1%) had penetrating injury. Pulmonary contusion was most frequent (314 patients; 67%). A total of 212 patients with chest injury underwent surgery (45.2%); urgent surgery was performed in 143 (67.5%), acute surgery in 49 (23.1%) and delayed surgery in 63 (29.7%) patients. Chest drainage was the major surgical procedure used in the whole group. Of 61 patients who died, 52 had chest injury. In this subgroup the most frequent cause of death was decompensated traumatic shock (26 patients; 50%). In the whole group, 32 polytrauma patients died within 24 hours of injury (61.5%). CONCLUSIONS Chest injury, almost always blunt, is often diagnosed in polytrauma patients. A prevalent cause of multiple trauma is a traffic accident. Chest injury most frequently involves pulmonary contusion. Nearly half of chest injuries require surgery, of which 2/3 are urgent procedures. The procedure most frequently performed in polytrauma patients with chest injury is chest drainage and this is also a sufficient procedure in 75% of surgically treated patients. polytrauma, chest injury, pulmonary contusion, surgical treatment, chest drainage.

Background and aims Published research on the relationship between disordered gambling and schizophrenia is limited. However, existing data suggest that individuals with schizophrenia/schizoaffective disorder may have a high prevalence of co-occurring disordered gambling. As such, effective strategies for screening and assessing gambling-related problems in individuals with psychosis are needed. The goal of this study was to explore the correlates of increased gambling frequency and chasing behavior, a hallmark feature of gambling disorder, in a sample of individuals with schizophrenia and schizoaffective disorders. Methods Data from 336 participants who met DSM-IV criteria for schizophrenia or schizoaffective disorder were used to examine differences between non-gamblers, infrequent gamblers, frequent gamblers who do not report chasing, and frequent gamblers who report chasing on a variety of associated features and symptoms of schizophrenia and disordered gambling. Results and discussion The results of the study support the conclusion that chasing behavior in individuals with schizophrenia/schizoaffective disorder lies on a continuum of severity, with more frequent gamblers endorsing greater chasing. Chasing was also associated with indicators of lower functioning across co-occurring disorders, such as greater problems with alcohol and drugs, greater gambling involvement, and a family history of gambling problems. The findings from the study suggest the utility of screening for chasing behavior as a brief and efficient strategy for assessing risk of gambling problems in individuals with psychotic-spectrum disorders.

To explore contributing factors (CF) associated to related critical patients safety incidents. SYREC study pos hoc analysis. A total of 79 Intensive Care Departments were involved. The study sample consisted of 1.017 patients; 591 were affected by one or more incidents. The CF were categorized according to a proposed model by the National Patient Safety Agency from United Kingdom that was modified. Type, class and severity of the incidents was analyzed. A total 2,965 CF were reported (1,729 were associated to near miss and 1,236 to adverse events). The CF group more frequently reported were related patients factors. Individual factors were reported more frequently in near miss and task related CF in adverse events. CF were reported in all classes of incidents. The majority of CF were reported in the incidents classified such as less serious, even thought CF patients factors were associated to serious incidents. Individual factors were considered like avoidable and patients factors as unavoidable. The CF group more frequently reported were patient factors and was associated to more severe and unavoidable incidents. By contrast, individual factors were associated to less severe and avoidable incidents. In general, CF most frequently reported were associated to near miss.

Sensitive skin appears as a very frequent condition, but there is no comparative data between countries. To perform an epidemiological approach to skin sensitivity in different European countries. An opinion poll was conducted in eight European countries: Belgium, France, Germany, Greece, Italy, Portugal, Spain and Switzerland. This sample (4506 persons) was drawn from a representative sample of each population aged 15 years or older. Sensitive or very sensitive skin was declared by 38.4% and slightly or not sensitive skin by 61.6%. Women declared more sensitive skin than men. A dermatological disease was declared by 31.2% of people with very sensitive skin, 17.6% of those with sensitive skin, 8.7% of those with slightly sensitive skin and 3.7% of those who do not have sensitive skin. A history of childhood atopic dermatitis was more frequent in patients with sensitive or very sensitive skin. The interviewees who declared that they had dry or oily skin also reported significantly more frequently sensitive or very sensitive skin than those with normal skin. Sensitive and very sensitive skins were clearly more frequent in Italy and France. This study is the first study that compares skin sensitivity in European countries. Prevalence is high, but significant differences are noted between these countries. Dermatological antecedents (or treatments?) could be involved in the occurrence of skin sensitivity.

Amyloidosis is a systemic disease frequently involving the myocardium and leading to functional disturbances of the heart. Amyloidosis can mimic other cardiac diseases. A conclusive clinical diagnosis of cardiac involvement can only be made by a combination of different diagnostic methods. In 7 patients with myocardial amyloidosis we used a combined first-pass and static scintigraphy with technetium-99 m-pyrophosphate. There was only insignificant myocardial uptake of the tracer. The first-pass studies however revealed reduced systolic function in 4/7 patients and impaired diastolic function in 6/7 patients. Therefore, although cardiac amyloid could not be demonstrated in the static scintigraphy due to amyloidmore » fibril amount and composition, myocardial functional abnormalities were seen in the first-pass study.« less

Studies of longitudinally extensive spinal cord lesions (LESCLs) in neuromyelitis optica (NMO) have focused on gray matter, where the relevant antigen, aquaporin-4 (AQP4), is abundant. Because spinal white matter pathology in NMO is not well characterized, we aimed to clarify spinal white matter pathology of LESCLs in NMO. We analyzed 50 spinal cord lesions from eleven autopsied NMO/NMO spectrum disorder (NMOSD) cases. We also evaluated LESCLs with three or fewer spinal cord attacks by 3-tesla MRI in 15 AQP4 antibody-positive NMO/NMOSD patients and in 15 AQP4 antibody-negative multiple sclerosis (MS) patients. Pathological analysis revealed seven cases of AQP4 loss and four predominantly demyelinating cases. Forty-four lesions from AQP4 loss cases involved significantly more frequently posterior columns (PC) and lateral columns (LC) than anterior columns (AC) (59.1%, 63.6%, and 34.1%, respectively). The posterior horn (PH), central portion (CP), and anterior horn (AH) were similarly affected (38.6%, 36.4% and 31.8%, respectively). Isolated perivascular inflammatory lesions with selective loss of astrocyte endfoot proteins, AQP4 and connexin 43, were present only in white matter and were more frequent in PC and LC than in AC (22.7%, 29.5% and 2.3%, P corr  = 0.020, and P corr  = 0.004, respectively). MRI indicated LESCLs more frequently affected PC and LC than AC in anti-AQP4 antibody-seropositive NMO/NMOSD (86.7%, 60.0% and 20.0%, P corr  = 0.005, and P corr  = 0.043, respectively) and AQP4 antibody-seronegative MS patients (86.7%, 73.3% and 33.3%, P corr  = 0.063, and P corr  = 0.043, respectively). PH, CP and AH were involved in 93.3%, 86.7% and 73.3% of seropositive patients, respectively, and in 53.3%, 60.0% and 40.0% of seronegative patients, respectively. NMO frequently and extensively affects spinal white matter in addition to central gray matter, especially in PC and LC, where isolated perivascular lesions with astrocyte endfoot protein loss may emerge. Spinal white matter involvement may also appear in early NMO, similar to cerebral white matter lesions. © 2016 International Society of Neuropathology.

To describe physicians' and patients' reasons for participating in office-based sales of dermatologic products. Survey data on the attitudes, opinions, and beliefs of dermatologists and their patients were analyzed. A market research study of office-based selling. Thirty dermatologists involved in direct selling from the office, 20 dermatologists not involved in direct selling, 22 patients who purchase products from their dermatologists' offices, and 25 office managers. The hypotheses of this study were formulated after the market research study had been done. The main outcome measure was the physicians' and patients' reported reasons for patients purchasing skin care products from dermatologists rather than from retail stores. "Trust" was the most frequent reason cited by physicians for patient purchases, while "physician knowledge" was the most frequent reason cited by the purchasing patients. The most common location to display the products was the waiting room (20 [67%] of the physicians). The most common types of products sold included glycolic acid products (15 [50%]), moisturizers (13 [43%]), sunscreens (12 [40%]), and alpha-hydroxy acid products other than glycolic acid (9 [30%]). The interaction between physicians who sell products in their offices and their patients is highlighted by 2 key elements of the physician-patient relationship: trust and physician knowledge.

Systemic sclerosis (SSc) is a generalized disorder of unknown etiology affecting the connective tissue of the body. It affects the skin and various internal organs. Gastrointestinal tract involvement is seen in almost 90% of the patients. Esophagus is the most frequently affected part of the gastrointestinal tract. Esophageal motility disturbance classically manifests as a reduced lower esophageal sphincter pressure (LESP) and loss of distal esophageal body peristalsis. Consequently, SSc patients may be complicated by erosive esophagitis and eventually by Barrett's esophagus and esophageal adenocarcinoma. Morphea, also known as localized scleroderma, is characterized by predominant skin involvement, with occasional involvement of subjacent muscles and usually sparing the internal organs. The involvement of esophagus in morphea has been studied very scarcely. The proposed study will investigate the esophageal involvement in the two forms of scleroderma (systemic and localized), compare the same and address any need of upper gastrointestinal evaluation in morphea (localized scleroderma) patients. 56 and 31 newly and already diagnosed cases of SSc and morphea respectively were taken up for the study. All the patients were inquired about the dyspeptic symptoms (heartburn and/or acid regurgitation and/or dysphagia). Upper gastrointestinal endoscopy, esophageal manometry and 24-hour pH monitoring were done in 52, 47 and 41 patients of SSc; and 28, 25 and 20 patients of morphea respectively. Esophageal symptoms were present in 39 cases (69.6%) of SSc which were mild in 22 (39.3%), moderate in 14 (25%), severe in three (5.3%); while only four cases (7.1%) of morphea had esophageal symptoms all of which were mild in severity. Reflux esophagitis was seen in 17 cases (32.7%) of SSc and only two cases (7.14%) of morphea. Manometric abnormalities were seen in 32 cases (68.1%) of SSc and none in morphea. Ambulatory 24-hour esophageal pH monitoring documented abnormal reflux in 33 cases (80.5%) of SSc and no such abnormality in morphea. While the esophageal involvement is frequent in SSc, no such motility disorder is seen in morphea. Meticulous upper gastrointestinal tract evaluation is justified only in SSc and not in morphea.

In the study cohort enrolled in a prospective open-label, multicenter trial conducted by the Japanese Study Group for MPO-ANCA-associated vasculitis (JMAAV), we conducted this sub-analysis to establish the validity of the Birminghan vasculitis activity score (BVAS) for Japanese patients with MPO-ANCA-associated vasculitis. We recorded the BVAS at the time of diagnosis, at 6 weeks after the diagnosis, and at 3, 6, 9, 12, 15 and 18 months after the diagnosis in this study. The most frequently involved organs in the patients were the lungs, kidneys and the nervous system. The kidney (BVAS; new/worse 69.2 %, persistent 40.4 %), general (BVAS; new/worse 67.3 %, persistent 53.8 %), chest (BVAS; new/worse 36.5 %, persistent 46.2 %) and nervous system (BVAS; new/worse 38.5 %, persistent 25.0 %) were the organ systems most frequently involved by the disease at the baseline. The BVAS for new/worse disease decreased immediately after induction therapy, while improvement of the BVAS for persistent disease after therapy differed among the organ systems. BVAS was demonstrated to be a valuable guide for selection of the optimal treatment. Thus, BVAS was also found to be a useful tool in Japanese patients for the assessment of disease activity and degree of organ damage in patients with MPO-ANCA-associated vasculitis.

The prevention and control of the nosocomial infections involve the knowledge of the most frequent type of microorganism isolated. In Mexico there are not national statistics to identify the main microorganisms that cause a nosocomial infection. It was conducted an analysis of all the culture results of the nosocomial infections reported by the Sistema de Vigilancia Epidemiológica Hospitalaria (Epidemiological Surveillance System) of the Instituto Mexicano del Seguro Social during the year 2013. The most frequent and relevant microorganisms were reported. 48 377 results from cultures of nosocomial infections were studied. Of these 13 207 (27.3 %) were from 25 high specialty medical units and 35 170 (72.6 %) from 197 second level medical units. The most frequently isolated microorganism was Escherichia coli with 8192 results (16.9 %), followed by the group of Coagulase-negative Staphylococci with 6771 cultures (14 %) and Pseudomonas aeruginosa with 5275 results (19.9 %). Slight differences between levels of care and specialized hospitals were observed. This study identifies the Escherichia coli, the group of Coagulase-negative Staphylococci and the Pseudomonas aeruginosa as the main microorganisms to prevent.

Assessment of hypoallergenicity of ten skincare products.

Sensitive skin is a common skin complaint frequently associated with skin diseases or adverse reactions to cosmetic products. Manufacturers have produced numerous products targeted for patients with sensitive skin and frequently label these products as being hypoallergenic. This term implies that the product may be less likely to cause an allergic reaction and be better suited for those with sensitive skin. However, there is no federal regulatory definition of this term and products may not have clinical support of their claim. Patch testing ingredients is frequently done to identify potential irritants; however, patch-testing product formulations may provide more realistic expectations about potential skin sensitivity and help support claims of hypoallergenicity. Ten skincare products were assessed for their sensitizing potential and hypoallergenicity in 14 repeat insult patch test clinical studies, involving over 2,000 subjects. In these studies, the products were deemed to be hypoallergenic if there was no evidence of sensitization or allergic reactions. The results from these trials demonstrated that all ten products were well tolerated, showed no sensitization or allergic reactions, and support claims of hypoallergenicity.

Abstract Aims: To identify and characterize the top-cited articles in the field of islet transplantation. Methods: We used the Science Citation Index Expanded database to identify the most frequently cited articles published after 1900. Articles were evaluated using the following characteristics: citation number, publication year, study design, references, country and institution of origin, authorship, and journal. Keyword analysis and citation networks were used to analyze research trends. Results: The most frequently cited articles received between 146 and 2988 citations; the median was 291. All of the most frequently cited articles were published between 1972 and 2012, and 85 articles were published after 1990. The most popular study design involved basic science (75 articles). The leading countries were the United States (US) and Canada, and the leading institutions were the University of Alberta, Canada, and the University of Minnesota, in the US. Journals specializing in diabetes or transplantation published more than half of the articles (n = 53, 52%), with the journal Diabetes publishing the largest number (n = 30). No association was found between a journal's impact factor and the number of top-cited articles it published. There was no correlation between the number of citations and the number of years since publication, authors, participating institutions, or countries involved. Top-cited articles focused on 2 themes: the use of antirejection immunotherapy or biocompatible encapsulations to prolong graft survival, and assessments of the efficacy of islet transplants, in particular, islet allografts. Conclusions: Our study can help researchers to identify and decipher the characteristics of top-cited articles in the field of islet transplantation. Just as clinically successful allografts are carried out using the Edmonton protocol, autografts and xenografts should be similarly strengthened to solve problems relating to immune rejection and islet sources, respectively.

To assess the incidence of attendance, type of injury, sport involved and management of sports injuries in children attending an Accident & Emergency (A&E) department. Children, aged between 5-16 years, presenting with an injury related to sport, were studied over a period of three months. 1858 children attended the A&E department during the three month period. 238 (12.8%) were classified as sports injuries. Boys (71%) were injured more frequently than girls (29%). Injury rates in boys peaked at 14 years whereas in girls a peak occurred earlier at 12 years. Football was the most common sport implicated in injuries (39%). Rollerblading (14%), Rugby (8%), Basketball (7%) and Physical Education at school (7%) were the next most frequently involved sports. Soft tissue injuries dominated (61%). The upper limb was the most common anatomical area injured (46%). Other injuries involved the lower limb (36%), head and neck (15%) and the trunk (3%). Injuries to the wrist were the most frequent presentation accounting for 30 fractures and 30 soft tissue injuries (25%). The majority of children were discharged from the A&E department after treatment (71%). 26% were reviewed at out-patient clinics and 3% required hospital admission. No children were referred for physiotherapy. Children participate in sport and can be injured. The majority of sports injuries presenting to an A&E department appear to be of a minor nature and could be managed with simple first aid techniques by parents, teachers and coaches at the scene or by attending primary care in the first instance. Supervision of children, participation in organised sport and the use of protection devices may help to prevent serious injury.

Excessive use of cannabis may have long-term effects on cognitive abilities. Mild impairments have been found in several cognitive domains, particularly in memory and attention. It is not clear, however, whether these effects also occur with moderate, recreational use of cannabis. Furthermore, little is known about underlying brain correlates. The aim of this study is to assess brain function in frequent but relatively moderate cannabis users in the domains of working memory and selective attention. Functional magnetic resonance imaging was used to examine verbal working memory and visuo-auditory selective attention in ten frequent cannabis users (after 1 week of abstinence) and ten non-using healthy controls. Groups were similar in age, gender and estimated IQ. Cannabis users and controls performed equally well during the working memory task and the selective attention task. Furthermore, cannabis users did not differ from controls in terms of overall patterns of brain activity in the regions involved in these cognitive functions. However, for working memory, a more specific region-of-interest analysis showed that, in comparison to the controls, cannabis users displayed a significant alteration in brain activity in the left superior parietal cortex. No evidence was found for long-term deficits in working memory and selective attention in frequent cannabis users after 1 week of abstinence. Nonetheless, frequent cannabis use may affect brain function, as indicated by altered neurophysiological dynamics in the left superior parietal cortex during working memory processing.

Objectives This study aimed to explore the service needs and preferences of frequent emergency department users with mental health and addictions concerns who participated in a brief intensive case management intervention. Methods We conducted semi-structured individual interviews with 20 frequent emergency department users with mental health and addictions challenges, 13 service providers involved in the delivery of a brief case management intervention, and a focus group with intervention case managers. Thematic analysis was used to explore perceived service user profiles, service needs and preferences of care. Results Service users experienced complex health and social needs and social isolation, while exhibiting resilience and the desire to contribute. They described multiple instances of stigmatization in interactions with healthcare professionals. Components of the brief intensive case management intervention perceived to be helpful included system navigation, advocacy, intermediation, and practical needs assistance. Frequent service users valued relational responsiveness, a non-judgmental stance, and a recovery orientation in case managers. Conclusion Interventions for frequent service users in mental health may be enhanced by focusing on the engagement of formal and informal social supports, practical needs assistance, system navigation, advocacy and intermediation, and attention to the recovery goals of service users.

Genetic and epigenetic alterations involved in the pathogenesis of pancreatic acinar cell carcinomas (ACCs) are poorly characterized, including the frequency and role of gene-specific hypermethylation, chromosome aberrations, and copy number alterations (CNAs). A subset of ACCs is known to show alterations in the APC/β-catenin pathway which includes mutations of APC gene. However, it is not known whether, in addition to mutation, loss of APC gene function can occur through alternative genetic and epigenetic mechanisms such as gene loss or promoter methylation. We investigated the global methylation profile of 34 tumor suppressor genes, CNAs of 52 chromosomal regions, and APC gene alterations (mutation, methylation, and loss) together with APC mRNA level in 45 ACCs and related peritumoral pancreatic tissues using methylation-specific multiplex ligation probe amplification (MS-MLPA), fluorescence in situ hybridization (FISH), mutation analysis, and reverse transcription-droplet digital PCR. ACCs did not show an extensive global gene hypermethylation profile. RASSF1 and APC were the only two genes frequently methylated. APC mutations were found in only 7 % of cases, while APC loss and methylation were more frequently observed (48 and 56 % of ACCs, respectively). APC mRNA low levels were found in 58 % of cases and correlated with CNAs. In conclusion, ACCs do not show extensive global gene hypermethylation. APC alterations are frequently involved in the pathogenesis of ACCs mainly through gene loss and promoter hypermethylation, along with reduction of APC mRNA levels.

Churg-Strauss syndrome is a rare systemic vascularitis. This disease causes eosinophilic tissue infiltration. The most frequent manifestations are cortico-dependent asthma, mono- or polyneuropathy, paranasal sinus polyposis, and digestive and renal dysfunction. Salivary glands are very rarely involved. We describe a case of CSS in a patient presenting with bilateral parotid swelling. The morphological study of salivary glands revealed an unusual thickening of the salivary duct walls. Salivary gland involvement in Churg and Strauss syndrome can be difficult to demonstrate histologically; it does not usually present in the clinical foreground of the disease, and can be a source of misdiagnosis. The biopsy should be performed in the symptomatic gland, away from any previous corticoid treatment. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Traffic accidents are the most frequent cause of genitourinary injuries (GUI). Kidney injuries after trauma have been well described. However, there exists a paucity of data on other traumatic GUI after traffic accidents. The objective of this study was to analyze the frequency and type of all GUI, by user category, after traffic accidents. Patient cases were extracted from the trauma registry of the French department of Rhone from 1996 to 2013. We assessed the urogenital injuries presented by each of road user's categories. Severity injuries were coded with the Abbreviated Injury Scale and the Injury Severity Score. Kidney trauma was mapped with the classification of the American Association for the Surgery of Trauma. Multivariate prediction models were used for analysis of data. Of 162,690 victims, 963 presented with GUI (0.59%). 47% were motorcyclists, 22% were in a car, 18% on bicycles, and 9% were pedestrians. The most common organ injury was kidney (41%) followed by testicular (23%). Among the 208 motorists with a GUI, kidney (70%), bladder (10%), and adrenal gland (9%) were the most frequent lesions. Among the 453 motorcyclist victims with GUI, kidney (35%) and testicular (38%) traumas were the most frequent and 62% of injuries involved external genitalia. There were 175 cyclists with GUI, 70% of injuries involved external genitalia; penile traumas (23%) were the most frequent. In total, there were 395 kidney injuries, most being low grade. According to the American Association for the Surgery of Trauma kidney injuries were grade I, 59%; grade II, 11%; grade III, 16%; grade IV, 9%; grade V, 3%; and indeterminate, 2%. GUI is an infrequent trauma after traffic accidents, with kidneys being the most commonly injured. Physicians must maintain a high awareness for external genitalia injuries in motorcyclists and cyclists. Prognostic and epidemiologic study, level III.

This study characterizes the magnetic resonance (MR) appearances of facial nerve schwannoma (FNS). We hypothesize that the extent of FNS demonstrated on MR will be greater compared to prior computed tomography studies, that geniculate involvement will be most common, and that cerebellar pontine angle (CPA) and internal auditory canal (IAC) involvement will more frequently result in sensorineural hearing loss (SNHL). Retrospective study. Clinical, pathologic, and enhanced MR imaging records of 30 patients with FNS were analyzed. Morphologic characteristics and extent of segmental facial nerve involvement were documented. Median age at initial imaging was 51 years (range, 28-76 years). Pathologic confirmation was obtained in 14 patients (47%), and the diagnosis reached in the remainder by identification of a mass, thickening, and enhancement along the course of the facial nerve. All 30 lesions involved two or more contiguous segments of the facial nerve, with 28 (93%) involving three or more segments. The median segments involved per lesion was 4, mean of 3.83. Geniculate involvement was most common, in 29 patients (97%). CPA (P = .001) and IAC (P = .02) involvement was significantly related to SNHL. Seventeen patients (57%) presented with facial nerve dysfunction, manifesting in 12 patients as facial nerve weakness or paralysis, and/or in eight with involuntary movements of the facial musculature. This study highlights the morphologic heterogeneity and typical multisegment involvement of FNS. Enhanced MR is the imaging modality of choice for FNS. The neuroradiologist must accurately diagnose and characterize this lesion, and thus facilitate optimal preoperative planning and counseling.

Scleroderma featuring rare connective tissue disease that manifests as skin sclerosis and variable systemic involvement. Two categories of scleroderma are known: systemic sclerosis, characterized by cutaneous sclerosis and visceral involvement and localized scleroderma or morphea which classically presents benign evolution and self-limited, confined to the skin and/or underlying tissue. Recent studies show that the localized form may possibly course with involvement of internal organs and variable morbidity. This study aimed to determine the demographic characteristics, the prevalence of systemic manifestations and laboratory findings, as well as the association with autoimmune diseases, and the evolution of neurological findings, both clinical as brain MRI in patients with scleroderma of the face and its relation with the activity skin. Patients with localized scleroderma with facial involvement were evaluated and underwent neurological examination, magnetic resonance imaging and ophthalmology evaluation. After 3years, the patients were subjected again to MRI. We studied 12 patients with localized scleroderma of the face. Of this total, headache being the most frequent complaint found in 66.7% of patients, 33.3% had neurological changes possibly associated with scleroderma. As for ophthalmologic evaluation, 25% of patients showed abnormalities. The most frequent parenchymal finding was the presence of lesions with hyperintense or hypointense signal in 75% of patients, followed by ventricular asymmetry at 16.7%. Of the patients who had neurological deficits, 75% also had a change to MRI. In all patients, imaging findings after 3years were unchanged. During this interval of 3years, 25% of patients showed signs of activity of scleroderma. Patients with localized scleroderma of the face have a high prevalence of neurological and ophthalmological changes. Based on these findings, we suggest that all cases of localized scleroderma of the face should be thoroughly examined for the presence of systemic changes. Copyright © 2013 Elsevier B.V.

Polymyalgia rheumatica (PMR) is a common inflammatory disease in older people characterized by shoulder and/or pelvic girdle, and cervical and, occasionally, lumbar pain. Interspinous bursitis has been suggested as a potential cause of spinal symptoms. We evaluated, by 18 F-fluorodeoxyglucose (FDG) positron emission tomography integrated with computed tomography (PET/CT), the vertebral structures involved in PMR in a cohort of consecutive, untreated patients. Sixty-five consecutive patients with PMR were studied. After a standardized physical examination, which included evaluation of pain and tenderness in the vertebral column, they underwent FDG-PET/CT. Sites of increased uptake and their correlation with spontaneous and provoked pain were recorded. For comparison, FDG-PET/CT was performed also in 65 age- and sex-matched controls and in 10 rheumatoid arthritis (RA) patients. The most frequent site of spontaneous and provoked pain was the cervical portion. FDG uptake was more frequent in the lumbar portion than at any other location, and in the cervical rather than in the thoracic portion (P <0.0001). No correlation was found between uptake and spontaneous or provoked pain. There was an association between presence of cervical and lumbar bursitis (r = 0.34, P = 0.007). None of the control patients and one out of ten RA patients showed interspinous bursitis. Interspinous bursitis is a frequent finding in the lumbar spine of patients with PMR. However, it is not associated with clinical symptoms and can hardly explain the spinal pain reported by the patients. Cervical pain is more frequent than lumbar pain in PMR patients and may be caused by shoulder girdle involvement.

To investigate which spinal mobility measures (SMMs) are most frequently impaired in patients with ankylosing spondylitis (AS), whether a hierarchy of impairment can be established, and whether assessing fewer measures sufficiently captures impairment in spinal mobility. Patients from the Outcome in Ankylosing Spondylitis International Study were followed up for 12 years. SMMs were considered impaired when falling below predefined cutoffs, derived from normal individuals. The proportion of patients in whom each SMM was impaired was calculated using baseline observation. In patients with ≥1 impaired SMM, we investigated how often impairment in spinal mobility would be missed if only a fixed number of SMMs was assessed. Analyses were repeated using all 12-year observations. A total of 216 patients were included (70% males). Lateral spinal flexion (LSF) was the most frequently impaired measure, followed by the modified Schober (mSchober) test, tragus-to-wall, cervical rotation, intermalleolar distance, and chest expansion measures, respectively. This hierarchy was strikingly consistent over time, and independent of sex, symptom duration, and presence of syndesmophytes. In patients with ≥1 impaired SMM, LSF was impaired most frequently (86%), followed by the mSchober test (58%). If only LSF was measured, 14% of patients with impairment in any SMM would be missed; if additionally the mSchober test was measured, 9% would be missed. LSF followed by the mSchober test are the most frequently impaired mobility measures in AS, reflecting an earlier involvement of the lumbar spine, followed by involvement of the thoracic and cervical spine. In clinical practice LSF and the mSchober test suffice to screen impairment in spinal mobility. © 2015, American College of Rheumatology.

Purpose: To determine clinical factors for predicting the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer. Methods and Materials: The study group consisted of 109 patients with esophageal cancer of T1-4 and Stage I-III who were treated with definitive radiotherapy and achieved a complete response of their primary lesion at Kyushu University Hospital between January 1998 and December 2007. Esophageal stenosis was evaluated using esophagographic images within 3 months after completion of radiotherapy. We investigated the correlation between esophageal stenosis after radiotherapy and each of the clinical factors with regard to tumors andmore » therapy. For validation of the correlative factors for esophageal stenosis, an artificial neural network was used to predict the esophageal stenotic ratio. Results: Esophageal stenosis tended to be more severe and more frequent in T3-4 cases than in T1-2 cases. Esophageal stenosis in cases with full circumference involvement tended to be more severe and more frequent than that in cases without full circumference involvement. Increases in wall thickness tended to be associated with increases in esophageal stenosis severity and frequency. In the multivariate analysis, T stage, extent of involved circumference, and wall thickness of the tumor region were significantly correlated to esophageal stenosis (p = 0.031, p < 0.0001, and p = 0.0011, respectively). The esophageal stenotic ratio predicted by the artificial neural network, which learned these three factors, was significantly correlated to the actual observed stenotic ratio, with a correlation coefficient of 0.864 (p < 0.001). Conclusion: Our study suggested that T stage, extent of involved circumference, and esophageal wall thickness of the tumor region were useful to predict the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer.« less

Factors contributing to young moped rider accidents in Denmark.

PubMed

Møller, Mette; Haustein, Sonja

2016-02-01

Young road users still constitute a high-risk group with regard to road traffic accidents. The crash rate of a moped is four times greater than that of a motorcycle, and the likelihood of being injured in a road traffic accident is 10-20 times higher among moped riders compared to car drivers. Nevertheless, research on the behaviour and accident involvement of young moped riders remains sparse. Based on analysis of 128 accident protocols, the purpose of this study was to increase knowledge about moped accidents. The study was performed in Denmark involving riders aged 16 or 17. A distinction was made between accident factors related to (1) the road and its surroundings, (2) the vehicle, and (3) the reported behaviour and condition of the road user. Thirteen accident factors were identified with the majority concerning the reported behaviour and condition of the road user. The average number of accident factors assigned per accident was 2.7. Riding speed was assigned in 45% of the accidents which made it the most frequently assigned factor on the part of the moped rider followed by attention errors (42%), a tuned up moped (29%) and position on the road (14%). For the other parties involved, attention error (52%) was the most frequently assigned accident factor. The majority (78%) of the accidents involved road rule breaching on the part of the moped rider. The results indicate that preventive measures should aim to eliminate violations and increase anticipatory skills among moped riders and awareness of mopeds among other road users. Due to their young age the effect of such measures could be enhanced by infrastructural measures facilitating safe interaction between mopeds and other road users. Copyright © 2015 Elsevier Ltd.

Lymph node tuberculosis is the most frequent form of extrapulmonary tuberculosis, especially in immunocompromised patients. We have studied patients with proven lymph node tuberculosis in the Department of Infectious Diseases at Pitié-Salpêtrière Hospital, Paris, between January 1997 and January 2002. Clinical presentation, microbiological diagnosis and treatment were analyzed in 13 HIV infected and 19 non-HIV infected patients. A risk factor for tuberculosis was present in all cases (HIV infection, immigration, life in community, poverty, past history of tuberculosis and IVDU). The median duration between the onset of symptoms and diagnosis was longer for HIV infected (2 months) compared with non-HIV infected patients (1 month). At the time of the diagnosis, general symptoms were present in >50% of patients of both groups. In HIV infected patients, abdominal lymph node involvement was more frequent (P < 0.05). All the non-HIV infected and 85% of HIV infected patients had peripheral adenopathies. A pulmonary tuberculosis was noted in more than half of the cases (53% non-HIV and 69% HIV patients). Inflammatory parameters and liver function tests were frequently abnormal in both groups. Hyponatremia was more frequent in HIV patients (P < 0.05). TB skin testing was more frequently positive and phlyctenular in non-HIV infected patients (P < 0.05). In this study, direct examination of the needle aspirate from infected lymph nodes was rarely positive; cultures were more frequently positive after biopsy compared to needle-aspiration. The median duration of treatment was 9 months for the two groups (6-24 months). Three HIV infected patients were infected by mycobacteria resistant to at least one antibiotic (isoniazid, 1; rifampicin, 1; isoniazid, streptomycin, etambutool, 1). All the patients recovered.

Introduction Dermatoses affecting palms and soles are among the most difficult of all dermatological therapeutic problems. Many previous studies have focused on the specific diseases of palmoplantar dermatoses. However, none of them have included a comprehensive study of palmoplantar dermatoses. Aims: To study the epidemiological aspects like age distribution, sex distribution, the dermatoses affecting the palms & soles and the frequency of involvement of palms, soles or both palms & soles, in patient with palmoplantar dermatoses. Materials and Methods This cross sectional study was conducted in the Department of Dermatology between October 2011 to September 2013. First 300 cases attending the department of dermatology primarily with complaints pertaining to palms and soles were enrolled in the study. After taking consent a detailed history and clinical examination pertaining to the aim of the study was recorded and analysed, which included inspection of morphology and distribution of lesions and palpation of any swelling. Direct microscopic examination of scrapings, wet mounted with 10% potassium hydroxide was done for cases with scaly lesions. Those who had a pustule, gram staining was done. Patch testing using Indian Standard Battery Series was done for those cases of eczema. A sample for biopsy was taken when diagnosis could not be arrived clinically, and subjected to histopathological examination. Results In our study of 300 patients with palmoplantar dermatoses, 164 were females and 136 were males, the ratio observed being 1.2:1. The peak incidence was found in the age group 21-30 years, with 41 females (25%) and 35 males (25.7%). Most frequently affected individuals in this study were housewives (30%). The most common five diseases of palmoplantar dermatoses were palmoplantar psoriasis (20.7%), moniliasis (19%), palmoplantar hyperhidrosis (7%), keratolysis exfoliativa (6%) and pitted keratolysis (6%). Majority of patients had involvement of both palms and soles (44.3%) as compared to patients with involvement of only palm (28%) and only sole (27.3%). The commonest palmoplantar dermatoses with only palm involvement was keratolysis exfoliativa (16.7%), with only sole involvement was moniliasis (41%) and with both palms and soles involvement was palmoplantar psoriasis (41.4%). Associated nail changes were seen in 80 cases (26.6%), with maximum incidence in palmoplantar psoriasis (62.5%). Associated dermatological conditions were observed in 43 patients (14.3%). Conclusion Palmoplantar dermatoses are frequently encount-ered in the dermatologic field. Further investigation with a wider and larger population is necessary to understand the epidemiology, based on which accurate diagnosis and proper treatment could be achieved. PMID:27656539

The human leucocyte antigen (HLA) has been documented to be involved in various disease susceptibilities or in resistance against certain diseases. An important element in susceptibility and resistance to disease is ethnic genetic constitution. Cognizant of this, the present study aimed at studying the prevalence of particular HLA class II in a normal healthy Malay population which may serve as a guide for further genetic and immunological studies related to the Malay Malaysian population. The study involved 40 normal healthy Malay persons in Kelantan. HLA typing was conducted on venous blood samples through a polymerase chain reaction-sequence specific primer method (low resolution Olerup SSP© HLA Typing Kits). The study found HLA DR12 and HLA DQ8 to be the most frequent HLA class II type. HLA DQ5 was significantly associated with female subjects.

Preventing injection drug use among vulnerable youth is critical for reducing serious drug-related harms. Addiction treatment is one evidence-based intervention to decrease problematic substance use; however, youth frequently report being unable to access treatment services and the impact of this on drug use trajectories remains largely unexplored. This study examines the relationship between being unable to access addiction treatment and injection initiation among street-involved youth. Data were derived from the At-Risk Youth Study (ARYS), a prospective cohort of street-involved youth aged 14-26 who use illicit drugs, from September 2005 to May 2014. An extended Cox model with time-dependent variables was used to identify factors independently associated with injection initiation. Among 462 participants who were injection naïve at baseline, 97 (21 %) initiated injection drug use over study follow-up and 129 (28 %) reported trying but being unable to access addiction treatment in the previous 6 months at some point during the study period. The most frequently reported reason for being unable to access treatment was being put on a wait list. In a multivariable Cox regression analysis, being unable to access addiction treatment remained independently associated with a more rapid rate of injection initiation (Adjusted Hazard Ratio =2.02; 95 % Confidence Interval: 1.12-3.62), after adjusting for potential confounders. Inability to access addiction treatment was common among our sample and associated with injection initiation. Findings highlight the need for easily accessible, evidence-based addiction treatment for high-risk youth as a means to prevent injection initiation and subsequent serious drug-related harms.

The developing world has had limited quality research and in Pakistan, research is still in its infancy. We conducted a study to assess the proportion of junior faculty involved in research to highlight their attitude towards research, and identify the factors associated with their research involvement. A cross-sectional study was conducted in four medical universities/teaching hospitals in Pakistan, representing private and public sectors. A pre-tested, self-administered questionnaire was used to collect information from 176 junior faculty members of studied universities/hospitals. Logistic regression analysis was used to identify factors related to attitudes and barriers in research among those currently involved in research with those who were not. Overall, 41.5% of study subjects were currently involved in research. A highly significant factor associated with current research involvement was research training during the post-graduate period (p < 0.001). Other factors associated with current involvement in research were male gender, working in the public sector and previous involvement in research. Overall, a large majority (85.2%) of doctors considered research helpful in their profession and had a positive attitude towards research; nevertheless this positive attitude was more frequently reported by doctors who were currently involved in research compared to those who were not (OR = 4.69; 95% CI = 1.54-14.26). Similarly, a large proportion (83.5%) of doctors considered research difficult to conduct; higher by doctors who were not presently involved in research (OR = 2.74; 95% CI = 1.20-6.22) Less than half of the study participants were currently involved in research. Research output may improve if identified barriers are rectified. Further studies are recommended in this area.

Background The oral cavity has been frequently described as the only site of involvement or as the first manifestation of mucous membrane pemphigoid (MMP), being the gingival tissues often involved, but usually this has been effusively detailed in limited case series. This is a retrospective evaluation of the gingival involvement in 182 Italian patients with oral MMP. Material and Methods The diagnosis of MMP was established by both clinical morphology and direct immunofluorescence finding. Patient information (age, gender, risk factors and medical status) and parameters of manifestation (lesions’ distribution, site and type) were detailed. Results The mean age was 62 years for women (n=137) and 67 years for men (n=45). Patients had several sites of oral involvement; the gingiva was the most common one, affecting 151 patients (82.96%; 119 f - 32 m). Female subjects had more possibilities to develop gingival lesions than male patients (P = 0.005). Sixty-five patients (35.7%; 58 f - 7 m) had pure gingival involvement. Patients with lower gingival involvement statistically had more complaints (P = 0.006). Conclusions This report is one of the largest about predominantly oral MMP cases, detailing the very frequent gingival involvement; this could be crucial not only for oral medicine specialists but also for primary dental healthcare personnel and for periodontists. Key words:Mucous membrane pemphigoid, gingival status, clinical features. PMID:28160581

Involvement of the digestive system in AIDS pathologies or injuries is frequent. Aiming at comparing the frequency, the importance that these lesions have for death and the survival time in patients using or not using HAART, we studied 322 necropsies classified as follows: Group A - without antiretroviral drugs (185 cases); B - one or two antiretroviral drugs or HAART for less than six months (83 cases); C - HAART for six months or longer (54 cases). In the overall analysis of the digestive system, changes were present in 73.6% of cases. The most frequent was Candida infection (22.7%), followed by cytomegalovirus (19.2%), Histoplasma capsulatum (6.5%), mycobacteria (5.6%), and Toxoplasma gondii (4.3%). T. gondii infection was more frequent in group A compared with group C, and cytomegalovirus (CMV) was more frequent in group A compared with groups B and C (p < 0.05); 2.2% of the deaths were due to gastrointestinal bleeding. Regarding the segments, only in the large intestine, and only cytomegalovirus, were more frequent in group A compared with group C. We conclude that digestive system infections are still frequent, even with the use of HAART. However, the average survival time in group C was more than three times greater than the one in group A and nearly double that of group B, demonstrating the clear benefit of this therapy.

The reasons for the increase in childhood asthma over time are unclear. The indoor environment is of particular concern. An adverse role for synthetic bedding on asthma development in childhood has been suggested by cross-sectional studies that have found an association between synthetic pillow use and childhood wheeze. Prospective data on infant bedding have not been available. Bedding data at 1 month of age were available from an infant survey for children who were participating in a 1995 follow-up study (N = 863; 78% traced). The 1995 follow-up was embedded in a larger cross-sectional survey involving 6,378 seven year olds in Tasmania (N = 92% of eligible). Outcome measures included respiratory symptoms as defined in the International Study of Asthma and Allergies in Childhood protocol. Frequent wheeze was defined as more than 12 wheeze episodes over the past year compared with no wheeze. Synthetic pillow use at 1 month of age was associated with frequent wheeze at age 7 (adjusted relative risk [aRR] = 2.5; 95% confidence interval [CI] = 1.2-5.5) independent of childhood exposure. Current synthetic pillow and quilt use was strongly associated with frequent wheeze (aRR = 5.2; CI = 1.3-20.6). Substantial trends were evident for an association of increasing number of synthetic bedding items with frequent wheeze and with increasing wheeze frequency. Among children with asthma, the age of onset of asthma occurred earlier if synthetic bedding was used in infancy. In this cohort, synthetic bedding was strongly and consistently associated with frequent childhood wheeze. The association did not appear to be attributable to bedding choice as part of an asthma management strategy.

Clinico-pathologic study of odontogenic cysts in a Mexican sample population.

Odontogenic cysts are uncommon lesions that frequently behave agressively and attain a large size. Unfortunately, information on the relative incidence of these cysts from different populations is not abundant. In Mexico, for example, only a few examples have been reported. The aim of this study was to ascertain the frequency of odontogenic cysts in a Mexican sample and to compare these data with previously reported studies from other countries. The files of the Oral and Maxillofacial Pathology Diagnosis Service at the School of Dentistry at the Universidad Nacional Autónoma de México (UNAM) were reviewed and all accessions of odontogenic cysts were listed. Clinical and radiographic data were recorded and microscopic slides evaluated according to the most recent World Health Organization (WHO) classification (1992). Three hundred and four cases of odontogenic cysts (55.9% male predominance) were found. The most frequent odontogenic cysts were the following: periapical cyst (38. 8%); dentigerous cyst (35.5%), and odontogenic keratocyst (18.8%). Periapical cyst was more frequent in females, and maxillary anterior teeth were most commonly involved. Dentigerous cysts appeared in males at a rate of 64.8%, this cyst found more frequently between the 1st and 2nd decades of life and in the molar zone. Odontogenic keratocyst was more frequent in males (59.6%), between the 2nd and 4th decades of life and more common in the molar zone. More than 50% of the sample were aggressive cysts (dentigerous and keratocyst). Our results suggest that Mexican patients develop aggressive odontogenic cysts more commonly than other populations. Our figures point to the need for a precise diagnosis in order to institute the correct surgical procedure, prevent recurrence, and forestall more extensive tissue destruction.

Evolution of Genes Involved in Gamete Interaction: Evidence for Positive Selection, Duplications and Losses in Vertebrates

Genes encoding proteins involved in sperm-egg interaction and fertilization exhibit a particularly fast evolution and may participate in prezygotic species isolation [1], [2]. Some of them (ZP3, ADAM1, ADAM2, ACR and CD9) have individually been shown to evolve under positive selection [3], [4], suggesting a role of positive Darwinian selection on sperm-egg interaction. However, the genes involved in this biological function have not been systematically and exhaustively studied with an evolutionary perspective, in particular across vertebrates with internal and external fertilization. Here we show that 33 genes among the 69 that have been experimentally shown to be involved in fertilization in at least one taxon in vertebrates are under positive selection. Moreover, we identified 17 pseudogenes and 39 genes that have at least one duplicate in one species. For 15 genes, we found neither positive selection, nor gene copies or pseudogenes. Genes of teleosts, especially genes involved in sperm-oolemma fusion, appear to be more frequently under positive selection than genes of birds and eutherians. In contrast, pseudogenization, gene loss and gene gain are more frequent in eutherians. Thus, each of the 19 studied vertebrate species exhibits a unique signature characterized by gene gain and loss, as well as position of amino acids under positive selection. Reflecting these clade-specific signatures, teleosts and eutherian mammals are recovered as clades in a parsimony analysis. Interestingly the same analysis places Xenopus apart from teleosts, with which it shares the primitive external fertilization, and locates it along with amniotes (which share internal fertilization), suggesting that external or internal environmental conditions of germ cell interaction may not be the unique factors that drive the evolution of fertilization genes. Our work should improve our understanding of the fertilization process and on the establishment of reproductive barriers, for example by offering new leads for experiments on genes identified as positively selected.

Although fairly frequent in psychiatric in-patient, episodes of aggression/violence are mainly limited to verbal aggression, but the level of general health is significantly lower in nurses who report 'frequent' exposure to violent incidents, and there is disagreement between patients and staff concerning predictors of these episodes. We searched the Pubmed, Embase and PsychInfo databases for English, Italian, French or German language papers published between 1 January 1990 and 31 March 2010 using the key words "aggress*" (aggression or aggressive) "violen*" (violence or violent) and "in-patient" or "psychiatric wards", and the inclusion criterion of an adult population (excluding all studies of selected samples such as a specific psychiatric diagnosis other than psychosis, adolescents or the elderly, men/women only, personality disorders and mental retardation). The variables that were most frequently associated with aggression or violence in the 66 identified studies of unselected psychiatric populations were the existence of previous episodes, the presence of impulsiveness/hostility, a longer period of hospitalisation, non-voluntary admission, and aggressor and victim of the same gender; weaker evidence indicated alcohol/drug misuse, a diagnosis of psychosis, a younger age and the risk of suicide. Alcohol/drug misuse, hostility, paranoid thoughts and acute psychosis were the factors most frequently involved in 12 studies of psychotic patients. Harmony among staff (a good working climate) seems to be more useful in preventing aggression than some of the other strategies used in psychiatric wards, such as the presence of male nurses.

Behçet's syndrome (BS) shows a peculiar distribution, with a much higher prevalence in countries along the ancient Silk Road compared with rest of the world. BS also seems to follow a more severe course in ethnic groups with higher prevalence. Diagnosis depends on clinical findings. Criteria sets may not help in patients with less frequent types of involvement. Management strategies should be modified according to the age and sex of the patient and the organs involved. Being a serious health problem in endemic areas, BS also attracts global attention as a model to study inflammatory diseases of unknown cause. Copyright © 2013 Elsevier Inc. All rights reserved.

The human chromosomal fragile sites more often involved in constitutional deletions and duplications - A genetic and statistical assessment

Human chromosomal fragile sites (CFSs) are heritable loci or regions of the human chromosomes prone to exhibit gaps, breaks and rearrangements. Determining the frequency of deletions and duplications in CFSs may contribute to explain the occurrence of human disease due to those rearrangements. In this study we analyzed the frequency of deletions and duplications in each human CFS. Statistical methods, namely data display, descriptive statistics and linear regression analysis were applied to analyze this dataset. We found that FRA15C, FRA16A and FRAXB are the most frequently involved CFSs in deletions and duplications occurring in the human genome.

Librarians' roles in evidence-based dentistry education: a review of literature and a survey in North America.

Gu, Xiao-Mei

2010-10-01

This study describes the current roles of dental librarians in Evidence-based Dentistry (EBD) education including their perceptions of EBD and barriers to their involvement. A Web-based survey was distributed to the dental librarians in North America, with a 71% response rate. The results showed that the majority of dental librarians are playing multiple and diverse roles in EBD education. The most frequently cited barrier to their involvement is the low level of interest from the dental faculty/student/school. Most dental librarians felt competent in supporting EBD, although continuing education needs in both EBD and teaching skills were pointed out.

The aims of this study were to describe illegal drug abuse patterns in relation to the migration process and use of drug treatment centers among immigrant injected drug users (IDUs) involved in harm reduction programs, and to compare the characteristics of immigrant and native IDUs. Cross-sectional study of 748 IDUs aged ≥18 years attending harm reduction centers between 2008 and 2009. We explored differences in socio-economic status, illegal drug consumption, health status and use of treatment centers in native versus immigrant IDUs. We also described whether immigrant IDUs started using injected drugs before or after entering the host country. Immigrant IDUs tend to live alone more frequently, start injection at later ages, use heroin and inject it more frequently and use drug treatment centers less frequently than native IDUs. Seventy-six percent of immigrants began using illegal drugs before arriving at the host country. Those who started in other countries were residing in the host country for 5 years or less (63.9%). Overall, immigrant IDUs attended drug treatment centers (36.9%) less frequently than native IDUs (71.8%). In conclusion, migration could be a risk factor for illegal drug abuse initiation or increase in consumption, often with the adoption of local consumption patterns and aggravated due to a lower access to drug treatment centers.

Patterns of Primary Tumor Invasion and Regional Lymph Node Spread Based on Magnetic Resonance Imaging in Early-Stage Nasal NK/T-cell Lymphoma: Implications for Clinical Target Volume Definition and Prognostic Significance

DOE Office of Scientific and Technical Information (OSTI.GOV)

Wu, Run-Ye; Liu, Kang; Wang, Wei-Hu

Purpose: This study aimed to determine the pathways of primary tumor invasion (PTI) and regional lymph node (LN) spread based on magnetic resonance imaging (MRI) in early-stage nasal NK/T-cell lymphoma (NKTCL), to improve clinical target volume (CTV) delineation and evaluate the prognostic value of locoregional extension patterns. Methods and Materials: A total of 105 patients with newly diagnosed early-stage nasal NKTCL who underwent pretreatment MRI were retrospectively reviewed. All patients received radiation therapy with or without chemotherapy. Results: The incidences of PTI and regional LN involvement were 64.7% and 25.7%, respectively. Based on the incidence of PTI, involved sites surroundingmore » the nasal cavity were classified into 3 risk subgroups: high-risk (>20%), intermediate-risk (5%-20%), and low-risk (<5%). The most frequently involved site was the nasopharynx (35.2%), followed by the maxillary (21.9%) and ethmoid (21.9%) sinuses. Local disease and regional LN spread followed an orderly pattern without LN skipping. The retropharyngeal nodes (RPNs) were most frequently involved (19.0%), followed by level II (11.4%). The 5-year overall survival (OS), progression-free survival (PFS), and locoregional control (LRC) rates for all patients were 72.8%, 65.2%, and 90.0%, respectively. The presence of PTI and regional LN involvement based on MRI significantly and negatively affected PFS and OS. Conclusions: Early-stage nasal NKTCL presents with a high incidence of PTI but a relatively low incidence of regional LN spread. Locoregional spread followed an orderly pattern, and PTI and regional LN spread are powerful prognostic factors for poorer survival outcomes. CTV reduction may be feasible for selected patients.« less

Screening via noninvasive prenatal testing (NIPT) involving the analysis of cell-free DNA (cfDNA) from plasma has become readily available to screen for chromosomal and DNA aberrations through maternal blood. This report reviews a laboratory's experience with follow-up of positive NIPT screens for microdeletions. Patients that were screened positive by NIPT for a microdeletion involving 1p, 4p, 5p, 15q, or 22q who underwent diagnostic studies by either chorionic villus sampling or amniocentesis were evaluated. The overall positive predictive value for 349 patients was 9.2%. When a microdeletion was confirmed, 39.3% of the cases had additional abnormal microarray findings. Unrelated abnormal microarray findings were detected in 11.8% of the patients in whom the screen positive microdeletion was not confirmed. Stretches of homozygosity in the microdeletion were frequently associated with a false positive cfDNA microdeletion result. Overall, this report reveals that while cfDNA analysis will screen for microdeletions, the positive predictive value is low; in our series it is 9.2%. Therefore, the patient should be counseled accordingly. Confirmatory diagnostic microarray studies are imperative because of the high percentage of false positives and the frequent additional abnormalities not delineated by cfDNA analysis. © 2018 John Wiley & Sons, Ltd.

Plant food supplements (PFS) are products of increasing popularity and wide-spread distribution. Nevertheless, information about their risks is limited. To fill this gap, a poisons centres-based study was performed as part of the EU project PlantLIBRA. Multicentre retrospective review of data from selected European and Brazilian poisons centres, involving human cases of adverse effects due to plants consumed as food or as ingredients of food supplements recorded between 2006 and 2010. Ten poisons centres provided a total of 75 cases. In 57 cases (76%) a PFS was involved; in 18 (24%) a plant was ingested as food. The 10 most frequently reported plants were Valeriana officinalis, Camellia sinensis, Paullinia cupana, Melissa officinalis, Passiflora incarnata, Mentha piperita, Glycyrrhiza glabra, Ilex paraguariensis, Panax ginseng, and Citrus aurantium. The most frequently observed clinical effects were neurotoxicity and gastro-intestinal symptoms. Most cases showed a benign clinical course; however, five cases were severe. PFS-related adverse effects seem to be relatively infrequent issues for poisons centres. Most cases showed mild symptoms. Nevertheless, the occurrence of some severe adverse effects and the increasing popularity of PFS require continuous active surveillance, and further research is warranted.

Our environment is full of auditory events such as warnings or hazards, and their correct recognition is essential. We explored environmental sounds (ES) recognition in a series of studies. In study 1 we performed an Activation Likelihood Estimation (ALE) meta-analysis of neuroimaging experiments addressing ES processing to delineate the network of areas consistently involved in ES processing. Areas consistently activated in the ALE meta-analysis were the STG/MTG, insula/rolandic operculum, parahippocampal gyrus and inferior frontal gyrus bilaterally. Some of these areas truly reflect ES processing, whereas others are related to design choices, e.g., type of task, type of control condition, type of stimulus. In study 2 we report on 7 neurosurgical patients with lesions involving the areas which were found to be activated by the ALE meta-analysis. We tested their ES recognition abilities and found an impairment of ES recognition. These results indicate that deficits of ES recognition do not exclusively reflect lesions to the right or to the left hemisphere but both hemispheres are involved. The most frequently lesioned area is the hippocampus/insula/STG. We made sure that any impairment in ES recognition would not be related to language problems, but reflect impaired ES processing. In study 3 we carried out an fMRI study on patients (vs. healthy controls) to investigate how the areas involved in ES might be functionally deregulated because of a lesion. The fMRI evidenced that controls activated the right IFG, the STG bilaterally and the left insula. We applied a multimodal mapping approach and found that, although the meta-analysis showed that part of the left and right STG/MTG activation during ES processing might in part be related to design choices, this area was one of the most frequently lesioned areas in our patients, thus highlighting its causal role in ES processing. We found that the ROIs we drew on the two clusters of activation found in the left and in the right STG overlapped with the lesions of at least 4 out of the 7 patients' lesions, indicating that the lack of STG activation found for patients is related to brain damage and is crucial for explaining the ES deficit.

To identify risk and protective factors associated with thinking about or attempting suicide among youth involved in verbal and social bullying. We analyzed data on 130,908 students in the sixth, ninth, and twelfth grades responding to the 2010 Minnesota Student Survey. Among students involved in frequent bullying (once a week or more during the past 30 days), we compared those who did and did not report suicidal ideation or a suicide attempt during the past year. Separate analyses were conducted for perpetrators only, victims only, and bully-victims. Overall, 6.1% of students reported frequent perpetration only, 9.6% frequent victimization only, and 3.1% both. Suicidal thinking or a suicide attempt was reported by 22% of perpetrators only, 29% of victims only, and 38% of bully-victims. In logistic regression models controlling for demographic and other risk and protective factors, a history of self-injury and emotional distress were risk factors that cross-cut the three bullying involvement groups. Physical abuse, sexual abuse, a mental health problem, and running away from home were additional risk factors for perpetrators only and victims only. Parent connectedness was a cross-cutting protective factor, whereas stronger perceived caring by friends and by nonparental adults were additional protective factors for some groups. A range of risk and protective factors were associated with suicidal ideation and a suicide attempt among youth involved in verbal and social bullying. Findings may assist in identifying youth at increased risk for suicidal thinking and behavior and in promoting key protective factors. Copyright © 2013 Society for Adolescent Health and Medicine.

To study private-practice clients' perspective on reasons for psychotherapy termination and how these are related to demographic and treatment variables and to satisfaction with therapy. Eighty-four persons who had been in extended private-practice psychotherapy which ended in the preceding three years participated in the study. Mean number of months in treatment was 27.70 (SD = 18.70). Assessment included rating scales and open-ended questions assessing demographic variables, reasons for terminating therapy, and satisfaction with therapy. Quantitative results revealed that the most frequent reasons for termination were accomplishment of goals, circumstantial constraints and dissatisfaction with therapy, and that client satisfaction was positively related to positive reasons for termination. Qualitative results revealed two additional frequently mentioned reasons for termination: the client's need for independence and the client's involvement in new meaningful relationships. Findings suggest that psychotherapy termination may at times be required to facilitate the pursuit of personally meaningful goals.

Patient inertia and the status quo bias: when an inferior option is preferred.

Medical noncompliance is a major public-health problem. One potential source of this noncompliance is patient inertia. It has been hypothesized that one cause of patient inertia might be the status quo bias-which is the tendency to select the default choice among a set of options. To test this hypothesis, we created a laboratory analogue of the decision context that frequently occurs in situations involving patient inertia, and we examined whether participants would stay with a default option even when it was clearly inferior to other available options. Specifically, in Studies 1 and 2, participants were given the option to reduce their anxiety while waiting for an electric shock. When doing nothing was the status quo option, participants frequently did not select the option that would reduce their anxiety. In Study 3, we demonstrated a simple way to overcome status quo bias in a context relevant to patient inertia.

Mucous membrane pemphigoid belongs to the family of sub-epidermal bullous diseases and is clinically characterized by mucosal involvement leading to fibrosis and scarring. Cutaneous involvement is unfrequent and oral mucosa and conjunctivas are the most frequently involves mucosa. Treatment relies on anti-inflammatory and immunosuppressive drugs. The main goal is the limitation of the fibrosing potential of the autoimmune deposits within various mucous membranes. Copyright © 2010. Published by Elsevier Masson SAS.

There is a lack of Tunisian data on the frequency and clinical significance of different coronary artery anomalies. All patients who underwent coronary angiography from March 1996 to December 2006 were considered. Only patients with congenital anomalous aortic origin of the coronary artery were included. Among 7330adult patients who underwent diagnostic coronary angiography, 20 (0.27%) patients (13men; mean age 53.3years) had anomalies of the coronary artery origin. The right coronary artery was the vessel involved most frequently (n=10); it originated separately from the left sinus of Valsalva (SV) in three patients and from the posterior sinus of Valsalva in one patient. In the other patients, it arose from the left main coronary artery or its branches in a single coronary artery originating from the left sinus of Valsalva. Isolated anomalous left circumflex artery was the second most frequent anomaly (n=6). Isolated anomalous left anterior descending artery was seen in one patient. A single coronary artery arising from the right SV was seen in three patients. Atheroslerotic lesions were seen in eight cases. Four patients underwent coronary revascularization; the remainder received medical management. All 20 patients are alive and had an uneventful follow-up (mean 34.2months). In Tunisia, the incidence of congenital anomalous aortic origin of the coronary artery in adults is 0.27%. The right coronary artery is involved most frequently. Medical management seems promising.

Involvement of vesicle coat material in casein secretion and surface regeneration

PubMed Central

1976-01-01

The ultrastructure of the apical zone of lactating rat mammary epithelial cells was studied with emphasis on vesicle coat structures. Typical 40-60 nm ID "coated vesicles" were abundant, frequently associated with the internal filamentous plasma membrane coat or in direct continuity with secretory vesicles (SV) or plasma membrane proper. Bristle coats partially or totally covered membranes of secretory vesicles identified by their casein micelle content. This coat survived SV isolation. Exocytotic fusion of SV membranes and release of the casein micelles was observed. Frequently, regularly arranged bristle coat structures were identified in those regions of the plasma membrane that were involved in exocytotic processes. Both coated and uncoated surfaces of the casein-containing vesicles, as well as typical "coated vesicles", were frequently associated with microtubules and/or microfilaments. We suggest that coat materials of vesicles are related or identical to components of the internal coat of the surface membrane and that new plasma membrane and associated internal coat is produced concomitantly by fusion and integration of bristle coat moieties. Postexocytotic association of secreted casein micelles with the cell surface, mediated by finely filamentous extensions, provided a marker for the integrated vesicle membrane. An arrangement of SV with the inner surface of the plasma membrane is described which is characterized by regularly spaced, heabily stained membrane to membrane cross-bridges (pre-exocytotic attachment plaques). Such membrane-interconnecting elements may represent a form of coat structure important to recognition and interaction of membrane surfaces. PMID:1254641

Objective To conduct a systematic review of the effects of frequent family meals on psychosocial outcomes in children and adolescents, and to examine whether there are differences in outcomes between males and females. Data sources Studies were identified through a search of MEDLINE (1948 to fifth week of June 2011) and PsycINFO (1806 to first week of July 2011) using the Ovid interface. The MeSH terms and key words used both alone and in combination were family, meal, food intake, nutrition, diets, body weight, adolescent attitudes, eating behaviour, feeding behaviour, and eating disorders. Bibliographies of papers deemed relevant were also reviewed. Study selection The original search yielded 1783 articles. To be included in the analysis, studies had to meet the following criteria: have been published in a peer-reviewed journal in English; involve children or adolescents; discuss the role of family meals on the psychosocial outcomes (eg, substance use, disordered eating, depression) of children or adolescents; and have an adequate study design, including appropriate statistical methods for analyzing outcome data. Fourteen papers met inclusion criteria. Two independent reviewers studied and analyzed the papers. Synthesis Overall, results show that frequent family meals are inversely associated with disordered eating, alcohol and substance use, violent behaviour, and feelings of depression or thoughts of suicide in adolescents. There is a positive relationship between frequent family meals and increased self-esteem and school success. Studies show substantial differences in outcomes for male and female children and adolescents, with females having more positive results. Conclusion This systematic review provides further support that frequent family meals should be endorsed. All health care practitioners should educate families on the benefits of having regular meals together as a family. PMID:25676655

Tuberculosis is highly prevalent in Pakistan. It is a contagious disease and causes a lot of morbidity and mortality. Its treatment is costly especially for poor countries like Pakistan. But fortunately it is a preventable disease. Objective of this study was to analyse various epidemiological features of tuberculosis in District Kotli, a remote area of Northern Pakistan. This cross sectional study was conducted in District Kotli, Azad Kashmir from January to December 2009. Data was collected from eight national TB centres of District Kotli. It included all the diagnosed cases of tuberculosis, registered there during the study period. Various epidemiological aspects of these patients were analysed. Total number patients registered during the study period were 752. Of these 579 (76.99%) were pulmonary and 173 (23%) were extra-pulmonary tuberculosis (EPT). Total prevalence of tuberculosis was found to be 100.27 per 100,000. Prevalence of pulmonary TB was 77.2 while that of EPT was 23.07 per 100,000. There were 405 males (53.85%) and 347 females (46.14%). Most patients were 61-75 years of age (220, 29.25%). Overall 417 (55.44%) were 46-75 years. Housewives were affected most frequently (324, 43.08%). Labourers were also commonly involved (40.82%). All cause mortality was 29 (3.85%). Mortality due to tuberculosi as was 11 (1.04%). Among pulmonary tuberculosis, 259 (44.78%) were sputum smear positive and 320) (55.26%) were sputum smear negative. In EPT, most frequent was pleural effusion (74, 42%) and least frequent was skin involvement (3, 1.73%). Prevalence of tuberculosis in Kotli was lower than the overall prevalence in Pakistan. Male to female ratio was lower than that generally observed in Southeast Asia. It was more common in middle to old age population. Frequency was higher in housewives and labourers. Very significant proportion of pulmonary TB was sputum smear positive. Among EPT, pleural effusion was the most common mode of presentation.

Background Little is known about the quantity and reasons for use of palliative sedation in general practice. Aim To gain more insight into the trends of and reasons for palliative sedation in Dutch general practice. Design and setting Dynamic cohort study using registrations and questionnaire data of Dutch GPs. Method Data collected in the years from 2005 until 2011 in the Dutch Sentinel General Practice Network were analysed. Trends and reasons for use of palliative sedation were analysed using multilevel analyses to control for clustering of observations within general practices. Results From 2005–2011, 183 cases were reported from 56 general practices. The incidence of palliative sedation fluctuated between 33.7 per 100 000 patients in 2006 and 15.2 in 2011. No rise or decline during the period was observed. Palliative sedation was applied in 5.7% of all deaths and most frequently used in younger patients with cancer. The mean number of refractory symptoms was 2.6 (SD 1.2); pain (69.4%), dyspnoea (53.0%), and fear (39.3%). Patient involvement in decision making before the start of palliative sedation (87.4%) was less frequently present in patients suffering from cardiovascular or chronic obstructive pulmonary disease and in older patients compared to patients with cancer (P<0.05). Pending euthanasia requests were present in 20.8% of cases; the choice for palliative sedation in these cases was clearly motivated. Conclusion Palliative sedation is performed in a small proportion of dying patients in Dutch general practice, without a rise or decline observed from 2005 to 2011. Patients with non-cancer diseases are less frequently involved in decision making than patients with cancer, possibly related to sudden deterioration. PMID:24152481

Extranodal lymphomas (ENLs) comprise about a third of all non-Hodgkin lymphomas (NHL). Radiation therapy (RT) is frequently used as either primary therapy (particularly for indolent ENL), consolidation after systemic therapy, salvage treatment, or palliation. The wide range of presentations of ENL, involving any organ in the body and the spectrum of histological sub-types, poses a challenge both for routine clinical care and for the conduct of prospective and retrospective studies. This has led to uncertainty and lack of consistency in RT approaches between centers and clinicians. Thus far there is a lack of guidelines for the use of RT inmore » the management of ENL. This report presents an effort by the International Lymphoma Radiation Oncology Group (ILROG) to harmonize and standardize the principles of treatment of ENL, and to address the technical challenges of simulation, volume definition and treatment planning for the most frequently involved organs. Specifically, detailed recommendations for RT volumes are provided. We have applied the same modern principles of involved site radiation therapy as previously developed and published as guidelines for Hodgkin lymphoma and nodal NHL. We have adopted RT volume definitions based on the International Commission on Radiation Units and Measurements (ICRU), as has been widely adopted by the field of radiation oncology for solid tumors. Organ-specific recommendations take into account histological subtype, anatomy, the treatment intent, and other treatment modalities that may be have been used before RT.« less

This study identified and prioritized potential failure scenarios for natural gas drilling operations through an elicitation of people who work in the industry. A list of twelve failure scenarios of concern was developed focusing on specific events that may occur during the shale gas extraction process involving an operational failure or a violation of regulations. Participants prioritized the twelve scenarios based on their potential impact on the health and welfare of the general public, potential impact on worker safety, how well safety guidelines protect against their occurrence, and how frequently they occur. Illegal dumping of flowback water, while rated as the least frequently occurring scenario, was considered the scenario least protected by safety controls and the one of most concern to the general public. In terms of worker safety, the highest concern came from improper or inadequate use of personal protective equipment (PPE). While safety guidelines appear to be highly protective regarding PPE usage, inadequate PPE is the most directly witnessed failure scenario. Spills of flowback water due to equipment failure are of concern both with regards to the welfare of the general public and worker safety as they occur more frequently than any other scenario examined in this study.

Background: Opioid analgesics are high-alert medications known to cause adverse drug events. Objectives: The purpose of this study was to determine the cause of opioid incidents requiring administration of naloxone, an opioid reversal agent. The specific objectives were to determine the number of opioid incidents and the proportion of incidents documented through occurrence reporting and to characterize the incidents by phase in the medication-use process, by type of incident, and by drug responsible for toxic effects. Methods: A retrospective chart analysis was conducted using records from 2 acute care centres in the Regina Qu’Appelle Health Region. The study included inpatients who received naloxone for reversal of opioid toxicity resulting from licit, in-hospital opioid use. Cases were classified as preventable or nonpreventable. Preventable cases were analyzed to determine the phase of the medication-use process during which the incident occurred. These cases were also grouped thematically by the type of incident. The drug most likely responsible for opioid toxicity was determined for each case. The proportion of cases documented by occurrence reporting was also noted. Results: Thirty-six cases involving administration of naloxone were identified, of which 29 (81%) were deemed preventable. Of these 29 preventable cases, the primary medication incident occurred most frequently in the prescribing phase (23 [79%]), but multiple phases were often involved. The cases were grouped into 6 themes according to the type of incident. Morphine was the drug that most frequently resulted in toxic effects (18 cases [50%]). Only two of the cases (5.6%) were documented by occurrence reports. Conclusion: Preventable opioid incidents occurred in the acute care centres under study. A combination of medication safety initiatives involving multiple disciplines may be required to decrease the incidence of these events and to better document their occurrence. PMID:24159230

Posterior circulation stroke accounts for approximately 20% of all strokes with varied clinical presentation, which differ from strokes in anterior circulation, with reference to etiology, clinical features, and prognosis. Short penetrating and circumferential branches in the posterior circulation supply the brain stem, thalamus, cerebellum, occipital, and medial temporal lobes. We prospectively analyzed 80 participants of posterior circulation ischemic stroke from a registry of 944 participants attending a tertiary care referral university hospital. Patients were analyzed for demographics, stroke risk factors, clinical characteristics, neuroimaging, and stroke subtypes. Posterior circulation ischemic stroke accounted for 80 (8.5%) of 944 of all strokes and 80 (10.45%) of 765 of ischemic stroke. Sixty-three were males with mean age 51.7 ± 14.4 years. Twenty-one participants were young (defined as age less than 45 years). Hypertension was found to be the most common risk factor (63.75%). Vertigo was the most common clinical symptom reported in 45 (56.25%) cases. Sixty-eight (85%) patients had large artery disease, 8 (10%) had documented cardioembolic source, 3 (3.75%) small artery disease, and 2 (2.5%) vasculitis. Posterior cerebral artery was most commonly involved. Topographically distal intracranial involvement was most frequent (66.25%) followed by proximal (30%) and middle intracranial territory (3.75%). Our study demonatrated the occurrence of posterior circulation stroke in relatively younger age group compared to the Western world. We also found higher percentage of large artery disease, while cardioembolism as a less frequent cause of posterior circulation ischemic stroke in North Indian population. Distal territory involvement was most common in our study.

Truck drivers' opinion on road safety in Tanzania--a questionnaire study.

Even though the traffic fatality risk (fatalities per 100,000 inhabitants) in Tanzania is quite low, the fatality rate (fatalities per 10,000 vehicles) is one of the highest in the world. With increasing vehicle density this means that the number of people dying in traffic will increase dramatically in the near future. Therefore, it is important to implement measures to increase traffic safety as soon as possible, and in order to be able to do this in an efficient way, it is important to investigate where the main problems lie. Within the European Union (EU) project ASSET-Road a questionnaire study on road safety was conducted with 250 truck drivers in Tanzania. The study was done to increase the knowledge about the situation of the Tanzanian truckers, who are the most frequent road users in the country. The drivers were interviewed in 3 different towns in southern Tanzania, and participation was voluntary. The questionnaire treated demographics, the state of the drivers' vehicles, the frequency of breakdowns, and the maintenance of the vehicles. Further questions concerned driver behavior, crash involvement, crash risk, and crash mitigation. The drivers who participated in the study were predominantly male and their average age was 36 years. Truck drivers reported driving 10.6 h without a break on average, with several drivers reporting that they had to drive 24 h without rest. Around 40 percent of the trucks did not have any seat belts installed, with a larger share of older trucks lacking belts. Most of the drivers who had seat belts reported using them, however. Almost 40 percent of the drivers reported being involved in at least one crash, and 45 percent of those drivers had experienced fatal crashes. This underlines that the crash frequency per vehicle is very high, and the results are often severe, especially when heavy vehicles are involved. When asked what the 3 most common crash causations were, driver-related causes were named frequently. Drivers were said to be reckless, and further crash causations named were drunkenness, inattention, and sleepiness. One of the most frequently mentioned crash mitigation strategies was driver education, followed by improvement of the roads and the vehicles. The results indicate that countermeasures should be implemented in an integrated fashion, taking into account aspects such as driver, vehicle, infrastructure, legislature, and other road users.

Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes.All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed.Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS.Lower-extremity vein thrombosis associated with BS, when compared to LEVT due to other causes, had distinctive demographic and ultrasonographic characteristics, and had clinically a more severe disease course.

In literature, there is evidence that all stakeholders need to be involved in the curricula building process to make sure that health professionals are "educated" to meet the stakeholders' "demands". In Italy, the involvement of stakeholders in the definition of university curricula is ratified by various regulations. To describe the major experiences of stakeholder involvement in nursing education, identify the main stakeholders for nursing education, and the processes in which they are involved. The search strategy included an electronic exploration of the relevant databases. The search terms were: Stakeholders, Curriculum, Nursing Education combined with Boolean operators. The references of the retrieved articles were hand searched for additional related studies. Most of the studies identified were from the United Kingdom, Australia, and the USA. In Italy, no relevant studies were found. The most frequently identified stakeholders were: students, clinicians, educators, nurse managers. They were mainly involved during profound changes in the curricula and the implementation of new educational approaches. Stakeholders are mostly involved in countries with a private funding system for universities. Such funding systems have probably developed in the academia a greater propensity to involve stakeholders, to provide recognition of success when starting new programs, and are perceived more as marketing research. This seems contrary to the spirit of the Italian and European regulatory interventions, which instead, provide a structured commitment to consolidating and expanding the collaboration among universities, users, and the world of labor. This latter collaboration should facilitate internship activities, lifelong learning, and employability of the newly-graduated professionals.

The aim of this study was to examine the impact of different neural systems on monetary decision making in frequent poker gamblers, who vary in their degree of problem gambling. Fifteen frequent poker players, ranging from non-problem to high-problem gambling, and 15 non-gambler controls were scanned using functional magnetic resonance imaging (fMRI) while performing the Iowa Gambling Task (IGT). During IGT deck selection, between-group fMRI analyses showed that frequent poker gamblers exhibited higher ventral-striatal but lower dorsolateral prefrontal and orbitofrontal activations as compared with controls. Moreover, using functional connectivity analyses, we observed higher ventral-striatal connectivity in poker players, and in regions involved in attentional/motor control (posterior cingulate), visual (occipital gyrus) and auditory (temporal gyrus) processing. In poker gamblers, scores of problem gambling severity were positively associated with ventral-striatal activations and with the connectivity between the ventral-striatum seed and the occipital fusiform gyrus and the middle temporal gyrus. Present results are consistent with findings from recent brain imaging studies showing that gambling disorder is associated with heightened motivational-reward processes during monetary decision making, which may hamper one's ability to moderate his level of monetary risk taking. © 2015 Society for the Study of Addiction.

Emotional stress is one of the etiologic or anyway predisposing factors involved in a lot of oral pathologies. In fact, relations between stress effects and frequent diseases such as gastric ulcer or ulcerous colitis are today wellknown by everyone. Theories about a relation between this kind of etiology and tumours are only reported by some Authors and are at the level of hypotheses. Mouth is very weak in these situations, owing to its great interest as primary erogenous zone, and for this reason we find frequently oral pathologies in relation with psychosomatic medicine. In this report we tried to give a good help to the study of these diseases and to find an easy classification to use (really it is an hard work to do due to the variety of this numerous illnesses).

In the last 7 years, we have studied 123 patients with allergic reactions to topical arylpropionic anti-inflammatory drugs. We have investigated the rate of sensitization and the irritant potential of one of them, ketoprofen, and its cross-reactivity with such other derivatives as ibuproxam, ibuprofen, naproxen, fenoprofen, flurbiprofen, and thiaprofenic acid. Sensitization was single in most cases, and ketoprofen was the drug most often involved. The combination most frequently found was ketoprofen plus ibuproxam. The most frequent cross-reactions were to fragrance mix, especially cinnamic aldehyde and balsam of Peru, both contact and photocontact sensitizers. Because there is a ketonic group in the molecule of ketoprofen and cinnamic aldehyde and after conversion of thiaprofenic acid, this could be the trigger for this particular allergy and cross-reactivity.

The parieto-occipital region of the brain is most frequently and severely affected in subacute sclerosing panencephalitis (SSPE). The basal ganglia, cerebellum and corpus callosum are less commonly involved. Brainstem involvement is rarely described in SSPE, and usually there is involvement of other regions of the brain. We describe a patient with subacute sclerosing panencephalitis with brain magnetic resonance imaging showing extensive brainstem involvement without significant involvement of other cortical structures. Though rarely described in SSPE, one should be aware of such brainstem and cerebellum involvement, and SSPE should be kept in mind when brainstem signal changes are seen in brain MRI with or without involvement of other regions of brain to avoid erroneous reporting.

Unilateral Punctate Keratitis Secondary to Wallenberg Syndrome

We studied three patients who developed left unilateral punctate keratitis after suffering left-sided Wallenberg Syndrome. A complex evolution occurred in two of them. In all cases, neurophysiological studies showed damage in the trigeminal sensory component at the bulbar level. Corneal involvement secondary to Wallenberg syndrome is a rare cause of unilateral superficial punctate keratitis. The loss of corneal sensitivity caused by trigeminal neuropathy leads to epithelial erosions that are frequently unobserved by the patient, resulting in a high risk of corneal-ulcer development with the possibility of superinfection. Neurophysiological studies can help to locate the anatomical level of damage at the ophthalmic branch of the trigeminal nerve, confirming the suspected etiology of stroke, and demonstrating that prior vascular involvement coincides with the location of trigeminal nerve damage. In some of these patients, oculofacial pain is a distinctive feature. PMID:24882965

Neovascularization of the iris (NVI) is one of the most frequently studied intraocular vascular proliferations in animal models. Ectropion uveae has not been a consistent finding in these studies. In this study, a surgical model of ectropion uveae and iris neovascularization was developed that involved lensectomy, vitrectomy, bipolar cautery and transection of all three principal branch veins in the cat eye. Twelve of 14 eyes that received this procedure developed postoperative retinal detachments with a clinical picture of hemorrhagic retinopathy. These eyes progressed to a clinical picture of NVI within 1-7 wk. Eight eyes developed ectropion uveae for as much as 300 degrees. At the light microscopic level, a fibrovascular membrane was apparent on the anterior iris stroma in 9 of 14 eyes and further involved the angle in six eyes.

Developing countries have experienced a dramatic increase in the number of clinical studies in the last decades. The aim of this study was to describe 1) the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa) from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs) and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP) in Brazil from 2007 to 2011 and 2) the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1) the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP) and 2) Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC). Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011). Type 2 diabetes (26.0%) and breast cancer (20.5%)-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1) a clear trend toward more research involving human beings in Brazil, 2) good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3) a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

To conduct a systematic review of the effects of frequent family meals on psychosocial outcomes in children and adolescents, and to examine whether there are differences in outcomes between males and females. Studies were identified through a search of MEDLINE (1948 to fifth week of June 2011) and PsycINFO (1806 to first week of July 2011) using the Ovid interface. The MeSH terms and key words used both alone and in combination were family, meal, food intake, nutrition, diets, body weight, adolescent attitudes, eating behaviour, feeding behaviour, and eating disorders. Bibliographies of papers deemed relevant were also reviewed. The original search yielded 1783 articles. To be included in the analysis, studies had to meet the following criteria: have been published in a peer-reviewed journal in English; involve children or adolescents; discuss the role of family meals on the psychosocial outcomes (eg, substance use, disordered eating, depression) of children or adolescents; and have an adequate study design, including appropriate statistical methods for analyzing outcome data. Fourteen papers met inclusion criteria. Two independent reviewers studied and analyzed the papers. Overall, results show that frequent family meals are inversely associated with disordered eating, alcohol and substance use, violent behaviour, and feelings of depression or thoughts of suicide in adolescents. There is a positive relationship between frequent family meals and increased self-esteem and school success. Studies show substantial differences in outcomes for male and female children and adolescents, with females having more positive results. This systematic review provides further support that frequent family meals should be endorsed. All health care practitioners should educate families on the benefits of having regular meals together as a family. Copyright© the College of Family Physicians of Canada.

Bullying among siblings.

Parents are often concerned about repeated conflicts between their daughters and sons. However, there is little empirical research of sibling bullying. To conduct a review of existing studies of sibling bullying. Are there any associations between sibling bullying and peer bullying at school? What are the consequences of sibling bullying? Is there good justification why sibling bullying has been so neglected in research? Studies of sibling relationships were reviewed. Four quantitative studies were identified that report on both sibling and peer bullying. Sibling bullying is frequent with up to 50% involved in sibling bullying every month and between 16% and 20% involved in bullying several times a week. Experience of sibling bullying increases the risk of involvement in bullying in school. Both, bullying between siblings and school bullying make unique contributions to explaining behavioral and emotional problems. There is a clear dose-effect relationship of involvement of bullying at home and at school and behavioral or emotional problems. Those involved in both have up to 14 times increased odds of behavioral or emotional problems compared to those involved in only one context or not at all. The empirical evidence is limited and studies are mostly cross-sectional studies. Nevertheless, the review suggests that for those victimized at home and at school behavioral and emotional problems are highly increased. Sibling relationships appear to be a training ground with implications for individual well-being. Strengthening families and parenting skills and increasing sibling support is likely to reduce bullying and increase well-being.

Musculoskeletal involvement in sarcoidosis*, **

Sarcoidosis is a multisystem inflammatory disorder of unknown cause. It most commonly affects the pulmonary system but can also affect the musculoskeletal system, albeit less frequently. In patients with sarcoidosis, rheumatic involvement is polymorphic. It can be the presenting symptom of the disease or can appear during its progression. Articular involvement is dominated by nonspecific arthralgia, polyarthritis, and Löfgren's syndrome, which is defined as the presence of lung adenopathy, arthralgia (or arthritis), and erythema nodosum. Skeletal manifestations, especially dactylitis, appear mainly as complications of chronic, multiorgan sarcoidosis. Muscle involvement in sarcoidosis is rare and usually asymptomatic. The diagnosis of rheumatic sarcoidosis is based on X-ray findings and magnetic resonance imaging findings, although the definitive diagnosis is made by anatomopathological study of biopsy samples. Musculoskeletal involvement in sarcoidosis is generally relieved with nonsteroidal anti-inflammatory drugs or corticosteroids. In corticosteroid-resistant or -dependent forms of the disease, immunosuppressive therapy, such as treatment with methotrexate or anti-TNF-α, is employed. The aim of this review was to present an overview of the various types of osteoarticular and muscle involvement in sarcoidosis, focusing on their diagnosis and management. PMID:24831403

Industrial Relevance of Chromosomal Copy Number Variation in Saccharomyces Yeasts.

Chromosomal copy number variation (CCNV) plays a key role in evolution and health of eukaryotes. The unicellular yeast Saccharomyces cerevisiae is an important model for studying the generation, physiological impact, and evolutionary significance of CCNV. Fundamental studies of this yeast have contributed to an extensive set of methods for analyzing and introducing CCNV. Moreover, these studies provided insight into the balance between negative and positive impacts of CCNV in evolutionary contexts. A growing body of evidence indicates that CCNV not only frequently occurs in industrial strains of Saccharomyces yeasts but also is a key contributor to the diversity of industrially relevant traits. This notion is further supported by the frequent involvement of CCNV in industrially relevant traits acquired during evolutionary engineering. This review describes recent developments in genome sequencing and genome editing techniques and discusses how these offer opportunities to unravel contributions of CCNV in industrial Saccharomyce s strains as well as to rationally engineer yeast chromosomal copy numbers and karyotypes.

2017-01-01

ABSTRACT Enterococcus faecalis and Enterococcus faecium are common inhabitants of the human gastrointestinal tract, as well as frequent opportunistic pathogens. Enterococci cause a range of infections including, most frequently, infections of the urinary tract, catheterized urinary tract, bloodstream, wounds and surgical sites, and heart valves in endocarditis. Enterococcal infections are often biofilm-associated, polymicrobial in nature, and resistant to antibiotics of last resort. Understanding Enterococcal mechanisms of colonization and pathogenesis are important for identifying new ways to manage and intervene with these infections. We review vertebrate and invertebrate model systems applied to study the most common E. faecalis and E. faecium infections, with emphasis on recent findings examining Enterococcal-host interactions using these models. We discuss strengths and shortcomings of each model, propose future animal models not yet applied to study mono- and polymicrobial infections involving E. faecalis and E. faecium, and comment on the significance of anti-virulence strategies derived from a fundamental understanding of host-pathogen interactions in model systems.

2011-01-01

This study was conducted to explore whether preparing more complex meals was associated with higher food security status. This mixed-methods, community-based study involved the use of semistructured interviews to examine the cooking practices of a group of young, low-income women in Montreal. Fifty participants aged 18 to 35 were recruited at 10 locations in five low-income neighbourhoods. Food security status was the main outcome measure and the main exposure variable, "complex food preparation," combined the preparation of three specific food types (soups, sauces, and baked goods) using basic ingredients. Low-income women preparing a variety of meals using basic ingredients at least three times a week were more than twice as likely to be food secure as were women preparing more complex meals less frequently. Women who prepared more complex meals more frequently had higher food security. Whether this means that preparing more complex foods results in greater food security remains unclear, as this was an exploratory study.

The purpose of this study was to investigate the pattern of toothwear in the permanent teeth of 12-18-year-old Nigerian students. The study group comprised 176 individuals (67 males and 109 females) who had no carious cavity, restoration or fracture on any of their permanent teeth. Within the group, 86% had tooth surface loss that was limited to enamel and dentine. No statistically significant differences were observed between the sexes. The most commonly affected tooth was the lower first molar, while the occlusal surface was the most frequently involved. One student had toothwear with a predominantly erosive component as a result of frequent ingestion of low pH drinks, while another displayed toothbrush abrasion. Of those with toothwear, two (13.4%) had parafunctional activities. The cause of toothwear in 73.2% of the study population could not be ascertained. Some of it may be connected with the coarse, abrasive diets that many of the students admitted to consuming on a regular basis.

Recruitment and retention of research participants is often the most labor-intensive and difficult component of clinical trials. Poor recruitment and retention frequently pose as a major barrier in the successful completion of clinical trials. In fact, many studies are prematurely terminated, or their findings questioned due to low recruitment and retention rates. The conduct of clinical trials involving youth with a first episode of mental illness comes with additional challenges in recruitment and retention including barriers associated with engagement and family involvement. To develop effective early interventions for first episode mental illness, it is necessary to develop strategies to enhance recruitment and retention in this patient population. This article presents the recruitment and retention challenges experienced in two clinical trials: one involving participants experiencing a first episode of depression and one involving participants experiencing a first episode psychosis. Challenges with recruitment and retention are identified and reviewed at both the patient level and clinician level. Strategies that were implemented to enhance recruitment and retention in these two studies are also discussed. Finally, ethical issues to consider when implementing these strategies are also highlighted.

Background Interventions in occupational health often target worksites rather than individuals. The objective of this paper is to describe the (lack of) stability in units of analysis in occupational health and safety intervention projects directed toward worksites. Methods A case study approach is used to describe naturally occurring organizational changes in four, large, Nordic intervention projects that ran 3–5 years, covered 3–52 worksites, cost 0.25 mill–2.2 mill €, and involved 3–7 researchers. Results In all four cases, high rates of closing, merging, moving, downsizing or restructuring was observed, and in all four cases at least one company/worksite experienced two or more re-organizations during the project period. If individual worksites remained, ownership or (for publicly owned) administrative or legal base often shifted. Forthcoming closure led employees and managers to seek employment at other worksites participating in the studies. Key employees involved in the intervention process often changed. Conclusion Major changes were the rule rather than the exception. Frequent fundamental changes at worksites need to be taken into account when planning intervention studies and raises serious questions concerning design, analyses and interpretation of results. The frequent changes may also have deleterious implications for the potential effectiveness of many real life interventions directed toward worksites. We urge researchers and editors to prioritize this subject in order to improve the quality of future intervention research and preventive action. PMID:18554380

It predominantly affects fair-skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions.

The purpose of this study was to investigate the characteristics associated with fatal and non-fatal low-speed vehicle run-over (LSVRO) events in relation to person, incident and injury characteristics, in order to identify appropriate points for intervention and injury prevention. Data on all known LSVRO events in Queensland, Australia, over 11 calendar years (1999-2009) were extracted from five different databases representing the continuum of care (prehospital to fatality) and manually linked. Descriptive and multivariate analyses were used to analyse the sample characteristics in relation to demographics, health service usage, outcomes, incident characteristics, and injury characteristics. Of the 1641 LSVRO incidents, 98.4% (n=1615) were non-fatal, and 1.6% were fatal (n=26). Over half the children required admission to hospital (56%, n=921); mean length of stay was 3.4 days. Younger children aged 0-4 years were more frequently injured, and experienced more serious injuries with worse outcomes. Patterns of injury (injury type and severity), injury characteristics (eg, time of injury, vehicle type, driver of vehicle, incident location), and demographic characteristics (such as socioeconomic status, indigenous status, remoteness), varied according to age group. Almost half (45.6%; n=737) the events occurred outside major cities, and approximately 10% of events involved indigenous children. Parents were most commonly the vehicle drivers in fatal incidents. While larger vehicles such as four-wheel drives (4WD) were most frequently involved in LSVRO events resulting in fatalities, cars were most frequently involved in non-fatal events. This is the first study, to the authors' knowledge, to analyse the characteristics of fatal and non-fatal LSVRO events in children aged 0-15 years on a state-wide basis. Characteristics of LSVRO events varied with age, thus age-specific interventions are required. Children living outside major cities, and indigenous children, were over-represented in these data. Further research is required to identify the burden of injury in these groups. Published by the BMJ Publishing Group Limited.

For several decades scholars have studied media reporting on scientific issues that involve controversy. Most studies so far have focused on the western world. This article tries to broaden the perspective by considering China and comparing it to a western country. A content analysis of newspaper coverage of vaccination issues in the UK and China shows, first, that the government-supported 'mainstream position' dominates the Chinese coverage while the British media frequently refer to criticism and controversy. Second, scientific expertise in the British coverage is represented by experts from the health and science sector but by experts from health agencies in the Chinese coverage. These results are discussed with respect to implications for risk communication and scientists' involvement in public communication.

MiT family translocation renal cell carcinoma.

PubMed

Argani, Pedram

2015-03-01

The MiT subfamily of transcription factors includes TFE3, TFEB, TFC, and MiTF. Gene fusions involving two of these transcription factors have been identified in renal cell carcinoma (RCC). The Xp11 translocation RCCs were first officially recognized in the 2004 WHO renal tumor classification, and harbor gene fusions involving TFE3. The t(6;11) RCCs harbor a specific Alpha-TFEB gene fusion and were first officially recognized in the 2013 International Society of Urologic Pathology (ISUP) Vancouver classification of renal neoplasia. These two subtypes of translocation RCC have many similarities. Both were initially described in and disproportionately involve young patients, though adult translocation RCC may overall outnumber pediatric cases. Both often have unusual and distinctive morphologies; the Xp11 translocation RCCs frequently have clear cells with papillary architecture and abundant psammomatous bodies, while the t(6;11) RCCs frequently have a biphasic appearance with both large and small epithelioid cells and nodules of basement membrane material. However, the morphology of these two neoplasms can overlap, with one mimicking the other. Both of these RCCs underexpress epithelial immunohistochemical markers like cytokeratin and epithelial membrane antigen (EMA) relative to most other RCCs. Unlike other RCCs, both frequently express the cysteine protease cathepsin k and often express melanocytic markers like HMB45 and Melan A. Finally, TFE3 and TFEB have overlapping functional activity as these two transcription factors frequently heterodimerize and bind to the same targets. Therefore, on the basis of clinical, morphologic, immunohistochemical, and genetic similarities, the 2013 ISUP Vancouver classification of renal neoplasia grouped these two neoplasms together under the heading of "MiT family translocation RCC." This review summarizes our current knowledge of these recently described RCCs. Copyright © 2015 Elsevier Inc. All rights reserved.

Invasive group A streptococcal (GAS) infections cause significant morbidity and mortality. A national survey was initiated to assess the burden of invasive GAS infections in France, describe their clinical characteristics, and assess the molecular characteristics of GAS strains responsible for these infections. The survey was conducted in 194 hospitals, accounting for 51% of acute care hospital admissions in France. Clinical data, predisposing factors, and demographic data were obtained, and all GAS isolates were emm sequence typed. We identified 664 cases of invasive GAS infections, with an annual incidence of 3.1 per 100,000 population. The case-fatality ratio was 14% and rose to 43% in the case of streptococcal toxic shock syndrome. Bacteremia without identified focus (22%) and skin/soft tissue infections (30%) were the most frequent clinical presentations. Necrotizing fasciitis was frequent in adults (18%) and uncommon in children (3%). The 3 predominant emm types were emm1, emm89, and emm28, accounting for 33%, 16%, and 10% of GAS isolates, respectively. The emm1 type was associated with fatal outcomes and was more frequent in children than in adults. Six clusters of cases were identified, with each cluster involving 2 invasive cases due to GAS strains which shared identical GAS emm sequence types. Four clusters of cases involved eight postpartum infections, one family cluster involved a mother and child, and one cluster involved two patients in a nursing home. Invasive GAS infection is one of the most severe bacterial diseases in France, particularly in persons aged ≥ 50 years or when associated with toxic shock syndrome.

Spouses' involvement in their partners' diabetes management: associations with spouse stress and perceived marital quality.

Spouses frequently attempt to influence (control) or support their chronically ill partners' adherence behaviors. Studies have documented effects of spousal control and support on chronically ill individuals, but little is known about how these two forms of involvement in a partner's disease management may be associated with spouses' stress or the quality of their interactions with their ill partners. The current study sought to address this gap by examining spouses' day-to-day involvement in their marital partner's management of type 2 diabetes (n = 129). Multilevel analyses of daily diary data revealed that on days when spouses exerted control, they reported more stress and more tense marital interactions, although these associations were more pronounced when patients exhibited poor adherence, had been ill for a longer period of time, and had more comorbid health conditions. On days when spouses provided support, in contrast, they reported less stress and more enjoyable marital interactions. The findings from the current study suggest that spouses' day-to-day stress and quality of interactions with their partners are associated with spouses' involvement in their partners' disease management, with health-related social control and support exhibiting distinctive associations.

Recently, increasing attention has been paid to the emergence of the double burden of malnutrition within households. We provide an overview of the literature regarding this phenomenon by reviewing previous studies of the prevalence of double-burden households and associated factors together with the research methods used. Studies were identified from the electronic databases PubMed and Web of Science, using the same search terms for both. A total of thirty-five articles met the eligibility criteria, and 367 sets of prevalence data were extracted. In all, thirty-four articles were published in 2000 or later; twenty-four used secondary data and twenty-five focused on mother-child pairs. The ages of children varied from 0 to 19 years. All the studies used BMI as a nutritional indicator for adults. For children, height-for-age was most frequently used, whereas weight-for-age, weight-for-height and BMI-for-age were also used in multiple studies. The reported national prevalence of double-burden households varied from 0·0 to 26·8 % by country and year; however, few studies were directly comparable, because of differences in the combinations of undernourished and overweight persons, age ranges, nutritional indicators and cut-off points. Whereas many focused on African countries, a few involved Asian countries. Although urban residence, income and education were frequently assessed, the role of intermediate factors in nutritional status, such as diet and physical activity, remains unclear. It is recommended that future studies use comparable indicators and cut-off points, involve Asian countries, and investigate individual diet and physical activity.

Employing the conceptual model developed by Comeaux and Harrison (Coll Stud Aff J 30(1):75-87, 2011), this study explored the undergraduate experience of Division I athlete STEM graduates. Data collection involved 17 in-depth interviews with former athletes at two research-intensive, public institutions. Results revealed that pre-college characteristics, involvement in purposeful STEM-related activities, and sport participation, as well as academic support and guidance within athletic departments, play important roles in shaping the experiences of athletes who earn STEM degrees. Implications for student affairs professionals, faculty, and others who frequently interact with college athletes and are committed to creating more equitable educational environments are discussed.

Tilmicosin, or 20-deoxo-20-(3,5-dimethylpiperidin-1-yl)-desmycosin, is a macrolide antibiotic primarily utilized in livestock. This study examined 46 human exposure calls involving tilmicosin received by Texas poison centres during 1998-2003. The majority (91%) of the calls were received from northern and central Texas. All of the cases were unintentional exposures. The most frequent route of exposure was parenteral (48%). The majority of the patients were males (80%) and adults (84%). Only 46% of the patients were managed outside of health care facilities. Some sort of adverse medical outcome was reported in 93% of parenteral exposures and 54% of other-route exposures. However, only 21% of parenteral exposures and 15% of other-route exposures involved medical outcomes that were judged to be moderate or worse. No deaths were reported. The most frequently reported clinical effects among parenteral cases were dermal (79%), while only 9% of other-route exposures had dermal effects. Cardiovascular clinical effects were observed in a single case of parenteral exposure and a single case of other-route exposure. Although the majority of cases were managed with the assistance of health care facilities, the medical outcomes were usually not serious. Outcome depended on the route of exposure.

To determine the type, frequency and cause of the most frequent hostile behaviors in a sample of nurses in the Balearic Islands and the socio-professional variables involved. We performed a cross-sectional descriptive study. The sample was composed of 464 members of the association of nurses of the Balearic Islands (392 women and 49 men). Age ranged from 25 to 65 years (mean: 35.11; SD: 9.62); 368 worked in public institutions and 71 in private centers. The instrument used was the Psychological Mobbing Questionnaire. A total of 17.2% of the nurses believed they had experienced mobbing at work (men: 22.4%; women: 14.5%). Significant differences were found according to age, but not according to institution. The most frequent hostile behavior was related to distortion of information, criticism of the purported victim, and lack of professional consideration. The perpetrators of mobbing were mainly, and very significantly, the bosses. According to these results, one in five nurses in the Balearic Islands has experienced mobbing in the workplace. However, because of the low response rate, caution should be exercised when generalizing these results. Nevertheless, health institutions should bear these findings in mind to ensure standards of behavior that do not jeopardize workers' health and dignity.

Prior reports of Langerhans cell histiocytosis (LCH) suggest that isolated skin involvement is rare and often progresses to systemic disease. More rapid access to pediatric subspecialty care has likely led to more frequent representation of this condition. The purpose of this study is to characterize the natural history of skin-limited LCH in an era of increased access to pediatric subspecialty care. A retrospective chart review was performed on all patients newly diagnosed with LCH between 2001 and 2012 at the Children's Hospital of Wisconsin. Extensive review of laboratory, physical examination, and imaging reports was performed and data collected for patients with biopsy-proven skin LCH. Sixteen individuals with skin-limited LCH were identified. The median age at onset of skin eruption was birth (range, birth to 6 mo), and median duration of follow-up was 19.5 months (range, 2 wk to 10 y) from diagnosis. One patient (6%) developed pituitary disease and 1 patient (6%) had refractory skin involvement. All others experienced complete resolution. For patients without progressive or refractory disease, resolution of skin findings occurred within 7 months from onset. Progression of skin-limited to multisystem LCH likely may be less frequent than previously described.

Oculo-auriculo-vertebral spectrum (OAVS) is a rare condition characterized by the involvement of the first branchial arches. To investigate the ear abnormalities of a sample of patients with OAVS. The sample consisted of 12 patients with OAVS seen at the Clinical Genetics Unit, UFCSPA/CHSCPA. The study included only patients who underwent mastoid computed tomography and with normal karyotype. We performed a review of its clinical features, giving emphasis to the ear findings. Nine patients were male, the ages ranged from 1 day to 17 years. Ear abnormalities were observed in all patients and involved the external (n = 12), middle (n = 10) and inner ear (n = 3). Microtia was the most frequent finding (n = 12). The most common abnormalities of the middle ear were: opacification (n = 2), displacement (n = 2) and malformation of the ossicular chain. Agenesis of the internal auditory canal (n = 2) was the most frequent alteration of the inner ear. Ear abnormalities are variable in patients with OAVS and often there is no correlation between findings in the external, middle and inner ear. The evaluation of these structures is important in the management of individuals with OAVS.

Most frequent attendance in primary care is temporary, but persistent frequent attendance is expensive and may be suitable for psychological intervention. To plan appropriate intervention and service delivery, there is a need for research involving standardized psychiatric interviews with assessment of physical health and health status. To compare the mental and physical health characteristics and health status of persistent frequent attenders (FAs) in primary care, currently and over the preceding 2 years, with normal attenders (NAs) matched by age, gender and general practice. Case-control study of 71 FAs (30 or more GP or practice nurse consultations in 2 years) and 71 NAs, drawn from five primary care practices, employing standardized psychiatric interview, quality of life, health anxiety and primary care electronic record review over the preceding 2 years. Compared to NAs, FAs were more likely to report a lower quality of life (P < 0.001), be unmarried (P = 0.03) and have no educational qualifications (P = 0.009) but did not differ in employment status. FAs experienced greater health anxiety (P < 0.001), morbid obesity (P = 0.02), pain (P < 0.001) and long-term pathological and ill-defined physical conditions (P < 0.001). FAs had more depression including dysthymia, anxiety and somatoform disorders (all P < 0.001). Persistent frequent attendance in primary care was associated with poor quality of life and high clinical complexity characterized by diverse and often persistent physical and mental multimorbidity. A brokerage model with GPs working in close liaison with skilled psychological therapists is required to manage such persistent complexity. © The Author 2015. Published by Oxford University Press.

The introduction of molecular karyotyping technologies into the diagnostic work-up of patients with congenital disorders permitted the identification and delineation of novel microdeletion and microduplication syndromes. Interstitial 16p13.3 duplication, encompassing the CREBBP gene, which is mutated or deleted in the Rubinstein-Taybi syndrome, have been proposed to cause a recognisable syndrome with variable intellectual disability, normal growth, mild facial dysmorphism, mild anomalies of the extremities, and occasional findings such as developmental defects of the heart, genitalia, palate or the eyes. We here report the phenotypic and genotypic delineation of 9 patients carrying a submicroscopic 16p13.3 duplication, including the smallest 16p13.3 duplication reported so far. Careful clinical assessment confirms the distinctive clinical phenotype and also defines frequent associated features : marked speech problems, frequent ocular region involvement with upslanting of the eyes, narrow palpebral fissures, ptosis and strabismus, frequent proximal implantation of thumbs, cleft palate/bifid uvula and inguinal hernia. It also confirms that CREBBP is the critical gene involved in the duplication 16p13.3 syndrome. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

[Epidemiology and Clinical Presentation of Sarcoidosis].

Costabel, U; Wessendorf, T E; Bonella, F

2017-06-01

Sarcoidosis is a systemic disease of unknown aetiology. Typical histology shows epithelioid cell granulomas, and typical immunopathology enhanced Th1 type immune responses in the involved organs. The disease occurs worldwide, but more frequently in northern countries than in the south. In Germany, the incidence is estimated to be 10 per 100,000, and the prevalence 44-48 per 100,000. Sarcoidosis usually affects adults under 50 years of age, but can also be seen in children, adolescents and in the elderly. Women are more frequently affected than men. Familial clusters can occur. The clinical presentation of sarcoidosis varies widely and depends on the manifestations in the individual organ. Systemic symptoms include fatigue, night sweats, weight loss, fever, arthralgia and myalgia. Organ-specific symptoms include cough and dyspnoea, with pulmonary involvement, headache and palsy in neurosarcoidosis, arrhythmias and heart failure in cardiac sarcoidosis, and manifold skin lesions with skin involvement. Relapses are rarely seen in acute sarcoidosis, whereas the chronic form tends to relapse more frequently. Löfgren's syndrome, a specific phenotype of acute sarcoidosis, is characterised by bihilar lymphadenopathy, ankle arthritis and erythema nodosum. Chronic sarcoidosis can be asymptomatic, despite radiological changes, which may be extensive. By definition, sarcoidosis has become chronic after 2 years of disease with ongoing signs of activity. The long-term prognosis is generally good, but depends on the different organ manifestations and complications. Georg Thieme Verlag KG Stuttgart · New York.

To determine the distribution of odontogenic cysts diagnosed histologically over a period of 38 years in a Brazilian population according to age, gender and site affected and to compare these data with previously reported studies from other countries. A total of 1019 cases of odontogenic cysts diagnosed between 1970 and 2007 were studied. Clinical features obtained from the patient records and microscope slides were reviewed according to the 1992 World Health Organization classification. The mean age was 31.0 years, and there was a predominance of females. The most frequent odontogenic cysts were radicular cysts (61.4%), followed by dentigerous cysts (20.1%) and odontogenic keratocysts (6.4%). Radicular cysts were more frequent in females (62.0%), and the maxillary teeth were the site most commonly involved (63.05%). The peak incidence of dentigerous cysts occurred in the second decade of life, with the posterior region of the mandible being the site most affected (46.3%), followed by the anterior region of the maxilla (27.8%). Odontogenic keratocysts showed a peak incidence between the third and fourth decades of life and predominance among females. The posterior region of the mandible was the site most frequently affected (65.6%). The present results showed a similar frequency of odontogenic cysts in this Brazilian population and other populations around the world, with inflammatory cysts being identified as the most frequent odontogenic cyst. Radicular cysts, dentigerous cysts, and odontogenic keratocysts are the most common cystic lesions, accounting for 87.9% of all odontogenic cysts.

This paper presents an overview of the prospective cohort design of the Dutch Cannabis Dependence (CanDep) study, which investigates (i) the three-year natural course of frequent cannabis use (≥ three days per week in the past 12 months) and cannabis dependence; and (ii) the factors involved in the transition from frequent non-dependent cannabis use to cannabis dependence, and remission from dependence. Besides its scientific relevance, this knowledge may contribute to improve selective and indicated prevention, early detection, treatment and cannabis policies. The secondary objectives are the identification of factors related to treatment seeking and the validation of self report measures of cannabis use. Between September 2008 and April 2009, baseline data were collected from 600 frequent cannabis users with an average age of 22.1 years, predominantly male (79.3%) and an average cannabis use history of 7.1 years; 42.0% fulfilled a (12-month DSM-IV) diagnosis of cannabis dependence. The response rate was 83.7% after the first follow up at 18 months. The second and last follow-up is planned at 36 months. Computer assisted personal interviews (CAPI) were conducted which covered: cannabis use (including detailed assessments of exposure, motives for use and potency preference); use of other substances; DSM-IV internalizing and externalizing mental disorders; treatment seeking; personality; life events; social support and social functioning.

The number of studies where non-malignant pulmonary diseases are evaluated after occupational arsenic exposure is very few. To investigate the effects of occupational arsenic exposure on the lung by high-resolution computed tomography and pulmonary function tests. Retrospective cross-sectional study. In this study, 256 workers with suspected respiratory occupational arsenic exposure were included, with an average age of 32.9±7.8 years and an average of 3.5±2.7 working years. Hair and urinary arsenic levels were analysed. High-resolution computed tomography and pulmonary function tests were done. In workers with occupational arsenic exposure, high-resolution computed tomography showed 18.8% pulmonary involvement. In pulmonary involvement, pulmonary nodule was the most frequently seen lesion (64.5%). The other findings of pulmonary involvement were 18.8% diffuse interstitial lung disease, 12.5% bronchiectasis, and 27.1% bullae-emphysema. The mean age of patients with pulmonary involvement was higher and as they smoked more. The pulmonary involvement was 5.2 times higher in patients with skin lesions because of arsenic. Diffusing capacity of lung for carbon monoxide was significantly lower in patients with pulmonary involvement. Besides lung cancer, chronic occupational inhalation of arsenic exposure may cause non-malignant pulmonary findings such as bronchiectasis, pulmonary nodules and diffuse interstitial lung disease. So, in order to detect pulmonary involvement in the early stages, workers who experience occupational arsenic exposure should be followed by diffusion test and high-resolution computed tomography.

Heavy metal poisoning and concurrent septicemia

Poisoning occurring in animals caused by agents such as arsenic, lead, tin, and other necrotizing substances is often accompanied by a Clostridial septicemia. The toxins of the Clostridia involved bring about clinical signs and pathologic changes that differ considerably from those caused by the poisonous agent; thereby overshadowing those produced by the poison. The Clostridia involved most frequently are Clostridium septicum, sordelli, and novyi. Therapy in cases of poisoning by necrotizing substances should include measures to prevent possible Clostridial involvement.

To know the current state of surgical management of patients with abdominal trauma. We carried out a retrospective, observational, transversal study involving patients with abdominal trauma with clinical files wtih trauma who required surgery during the period of April 1, 1998 through March 30, 2003. There were 72 cases including nine male and 33 female patients. Mechanism of lesion was divided into closed and penetrating trauma, the latter group of patients divided into individuals with blunt wounds or with gunshot wounds. Most frequent early postoperative complication was hemorrhage, while most frequent late postoperative complication was acute renal failure. Causes of death were hypovolemic shock in four patients followed by two cases each with the following pathologies: acute respiratory insufficiency syndrome; myocardial infarct, and septic shock. Abdominal trauma is a frequent pathology in our environment, males the most affected patients, with penetrating trauma main lesion cause. Prolonged surgical time required hemotransfusions, and infectious processes together with processes related with tissular hypoxia are the most common cause of complications and death.

During the time we have been in a private company that provide schools with medical care, we were surprised by the frequent and constant phone calls received to ask for our services. This fact made us take the decision to carry out a survey to find out the accidents and the most frequent injuries. According to the retrospective study we realized throughout two different academic courses in several schools in Cantabria, the 3.23% of the students have any accidents or injuries. We found out children between 11 and 15 have the highest accident rate, being 10.8 % higher when boys (rather than girls) are involved. The most common injuries are contusions 42.85%, followed by sprains 23.45%, being blows the reason in 42% of the cases, and surprisingly acts of aggression in 1%. It was also unexpected to learn that gyms, where children are taught in physical education, have the highest percent on accident rate. All these inquiries lead us to think that age, play and sports are determinant factors in the accidents happened in the school area.

Peripheral neuropathies associated with antibodies directed to intracellular neural antigens.

PubMed

Antoine, J-C

2014-10-01

Antibodies directed to intracellular neural antigens have been mainly described in paraneoplastic peripheral neuropathies and mostly includes anti-Hu and anti-CV2/CRMP5 antibodies. These antibodies occur with different patterns of neuropathy. With anti-Hu antibody, the most frequent manifestation is sensory neuronopathy with frequent autonomic involvement. With anti-CV2/CRMP5 the neuropathy is more frequently sensory and motor with an axonal or mixed demyelinating and axonal electrophysiological pattern. The clinical pattern of these neuropathies is in keeping with the cellular distribution of HuD and CRMP5 in the peripheral nervous system. Although present in high titer, these antibodies are probably not directly responsible for the neuropathy. Pathological and experimental studies indicate that cytotoxic T-cells are probably the main effectors of the immune response. These disorders contrast with those in which antibodies recognize a cell surface antigen and are probably responsible for the disease. The neuronal cell death and axonal degeneration which result from T-cell mediated immunity explains why treating these disorders remains challenging. Copyright © 2014 Elsevier Masson SAS.

Objective General practitioners are the first point of contact in Danish out-of-hours (OOH) primary care. The large number of contacts implies that prescribing behaviour may have considerable impact on health-care expenditures and quality of care. The aim of this study was to examine the prevailing practices for medication prescription in Danish OOH with a particular focus on patient characteristics and contact type. Design and setting A one-year population-based retrospective observational study was performed of all contacts to OOH primary care in the Central Denmark Region using registry data. Main outcome measures Prescriptions were categorised according to Anatomical Therapeutic Chemical Classification (ATC) codes and stratified for patient age, gender and contact type (telephone consultation, clinic consultation or home visit). Prescription rates were calculated as number of prescriptions per 100 contacts. Results Of 644,777 contacts, 154,668 (24.0%) involved medication prescriptions; 21.9% of telephone consultations, 32.9% of clinic consultations and 14.3% of home visits. Around 53% of all drug prescriptions were made in telephone consultations. Anti-infective medications for systemic use accounted for 45.5% of all prescriptions and were the most frequently prescribed drug group for all contact types, although accounting for less than 1/3 of telephone prescriptions. Other frequently prescribed drugs were ophthalmological anti-infectives (10.5%), NSAIDs (6.4%), opioids (3.9%), adrenergic inhalants (3.0%) and antihistamines (2.3%). Conclusion About 25% of all OOH contacts involved one or more medication prescriptions. The highest prescription rate was found for clinic consultations, but more than half of all prescriptions were made by telephone. KEY POINTSAs the out-of-hours (OOH) primary care services cover more than 75% of all hours during a normal week, insight into the extent and type of OOH drug prescription is important.General practitioners (GPs) are responsible for more than 80% of all drug prescriptions in Denmark.Of all contacts 24.0% involved medication prescriptions; 21.9% of telephone consultations, 32.9% of clinic consultations and 14.3% of home visits.Of all prescriptions, 53% were made in telephone consultations.Anti-infective medications for systemic use accounted for 45.5% of all prescriptions, thereby being the most frequently prescribed drug group for all three contact types.

No study specifically analyzes trampoline fracture patterns across a large population. The purpose of this study was to determine such patterns. We queried the National Electronic Injury Surveillance System database for trampoline injuries between 2002 and 2011, and the patients were analyzed by age, sex, race, anatomic location of the injury, geographical location of the injury, and disposition from the emergency department (ED). Statistical analyses were performed with SUDAAN 10 software. Estimated expenses were determined using 2010 data. There were an estimated 1,002,735 ED visits for trampoline-related injuries; 288,876 (29.0%) sustained fractures. The average age for those with fractures was 9.5 years; 92.7% were aged 16 years or younger; 51.7% were male, 95.1% occurred at home, and 9.9% were admitted. The fractures were located in the upper extremity (59.9%), lower extremity (35.7%), and axial skeleton (spine, skull/face, rib/sternum) (4.4%-spine 1.0%, skull/face 2.9%, rib/sternum 0.5%). Those in the axial skeleton were older (16.5 y) than the upper extremity (8.7 y) or lower extremity (10.0 y) (P<0.0001) and more frequently male (67.9%). Lower extremity fractures were more frequently female (54.0%) (P<0.0001). The forearm (37%) and elbow (19%) were most common in the upper extremity; elbow fractures were most frequently admitted (20.0%). The tibia/fibula (39.5%) and ankle (31.5%) were most common in the lower extremity; femur fractures were most frequently admitted (57.9%). Cervical (36.4%) and lumbar (24.7%) were most common locations in the spine; cervical fractures were the most frequently admitted (75.6%). The total ED expense for all trampoline injuries over this 10-year period was $1.002 billion and $408 million for fractures. Trampoline fractures most frequently involve the upper extremity followed by the lower extremity, >90% occur in children. The financial burden to society is large. Further efforts for prevention are needed.

The ultimate goal of Data Mining is to determine the hidden information which is useful in making decisions using the large databases collected by an organization. This Data Mining involves many tasks that are to be performed during the process. Mining frequent itemsets is the one of the most important tasks in case of transactional databases. These transactional databases contain the data in very large scale where the mining of these databases involves the consumption of physical memory and time in proportion to the size of the database. A frequent pattern mining algorithm is said to be efficient only if it consumes less memory and time to mine the frequent itemsets from the given large database. Having these points in mind in this thesis we proposed a system which mines frequent itemsets in an optimized way in terms of memory and time by using cloud computing as an important factor to make the process parallel and the application is provided as a service. A complete framework which uses a proven efficient algorithm called FIN algorithm. FIN algorithm works on Nodesets and POC (pre-order coding) tree. In order to evaluate the performance of the system we conduct the experiments to compare the efficiency of the same algorithm applied in a standalone manner and in cloud computing environment on a real time data set which is traffic accidents data set. The results show that the memory consumption and execution time taken for the process in the proposed system is much lesser than those of standalone system.

The authors studied the incidence of protozoal and bacterial infection in 41 cases of Crohn disease und ulcerative colitis; the effect of anti infective therapy on the clinical course has also been tested. Patients with ulcerative colitis are more frequently involved in this type of complication than those with Crohn disease. Therapy has a positive influence on the course of the disease; therefore systematic study of the faeces for bacteria and parasites is necessary for a correct understanding of chronic inflammatory bowel disease and for specific treatment.

Background Type 1 diabetes (T1D) is a clinically heterogeneous disease. The presence of associated autoimmune diseases (AAID) may represent a distinct form of autoimmune diabetes, with involvement of specific mechanisms. The aim of this study was to find predictors of AAID in the Type 1 Diabetes Genetics Consortium (T1DGC) data set. Methods 3263 families with at least 2 siblings with T1D were included. Clinical information was obtained using questionnaires, anti-GAD and anti-IA-2 were measured and HLA-genotyping was performed. Siblings with T1D with and without AAID were compared and a multivariate regression analysis was performed to find predictors of AAID. T1D-associated HLA haplotypes were defined as the 4 most susceptible and protective, respectively. Results AAID was present in 14.4% of the T1D affected siblings. Age of diabetes onset, current age and time since diagnosis were higher, and there was a female predominance and more family history of AAID in the group with AAID, as well as more frequent anti-GAD and less frequent anti-IA2 positivity. Risk and protective HLA haplotype distributions were similar, though DRB1*0301-DQA1*0501-DQB1*0201 was more frequent in the group with AAID. In the multivariate analysis, female gender, age of onset, family history of AAID, time since diagnosis and anti-GAD positivity were significantly associated with AAID. Conclusions In patients with T1D, the presence of AAID is associated with female predominance, more frequent family history of AAID, later onset of T1D and more anti-GAD antibodies, despite longer duration of the disease. The predominance of certain HLA haplotypes suggests that specific mechanisms of disease may be involved. PMID:21744463

Thrombotic thrombocytopenic purpura (TTP) has a devastating prognosis without adapted management. Sources of misdiagnosis need to be identified to avoid delayed treatment. We studied 84 patients with a final diagnosis of severe (<10%) acquired ADAMTS13 deficiency-associated TTP from our National database that included 423 patients, who had an initial misdiagnosis (20% of all TTP). Main diagnostic errors were attributed to autoimmune thrombocytopenia, associated (51%) or not (37%) with autoimmune hemolytic anemia. At admission, misdiagnosed patients were more frequently females (P = .034) with a history of autoimmune disorder (P = .017) and had organ involvement in 67% of cases; they had more frequently antinuclear antibodies (P = .035), a low/undetectable schistocyte count (P = .001), a less profound anemia (P = .008), and a positive direct antiglobulin test (DAT) (P = .008). In multivariate analysis, female gender (P = .022), hemoglobin level (P = .028), a positive DAT (P = .004), and a low schistocytes count on diagnosis (P < .001) were retained as risk factors of misdiagnosis. Platelet count recovery was significantly longer in the misdiagnosed group (P = .041) without consequence on mortality, exacerbation and relapse. However, patients in the misdiagnosed group had a less severe disease than those in the accurately diagnosed group, as evidenced by less organ involvement at TTP diagnosis (P = .006). TTP is frequently misdiagnosed with autoimmune cytopenias. A low schistocyte count and a positive DAT should not systematically rule out TTP, especially when associated with organ failure. © 2017 Wiley Periodicals, Inc.

Genomic information on tumors from 50 cancer types cataloged by the International Cancer Genome Consortium (ICGC) shows that only a few well-studied driver genes are frequently mutated, in contrast to many infrequently mutated genes that may also contribute to tumor biology. Hence there has been large interest in developing pathway and network analysis methods that group genes and illuminate the processes involved. We provide an overview of these analysis techniques and show where they guide mechanistic and translational investigations.

Religion and remission of depression in medical inpatients with heart failure/pulmonary disease.

Koenig, Harold G

2007-05-01

The impact of religious involvement on time to remission of depression was examined in older medical inpatients with heart failure and/or chronic pulmonary disease (CHF/CPD). Inpatients older than 50 years with CHF/CPD were systematically diagnosed with depressive disorder using a structured psychiatric interview. Cox proportional hazards regression was used to examine the effects of religious involvement on time to remission, controlling for covariates. Of 1000 depressed patients identified at baseline, follow-up data on depression course were obtained on 87%. Patients involved in group-related religious activities experienced a shorter time to remission. Although numerous religious measures were unrelated by themselves to depression outcome, the combination of frequent religious attendance, prayer, Bible study, and high intrinsic religiosity, predicted a 53% increase in speed of remission (HR 1.53, 95% CI 1.20-1.94, p = 0.0005, n = 839) after controls. Patients highly religious by multiple indicators, particularly those involved in community religious activities, remit faster from depression.

Efficacy of SYBR 14/propidium iodide viability stain for the amphibian chytrid fungus Batrachochytrium dendrobatidis.

2010-01-25

The amphibian chytrid fungus Batrachochytrium dendrobatidis is a recently described pathogen that has been implicated as a causal agent in the global decline in amphibians. Research into its biology and epidemiology has frequently involved in vitro experimentation. However, this research is currently limited by the inability to differentiate between viable and inviable zoospores. Stains are frequently used to determine cell viability, and this study tested a 2-colour fluorescence assay for the detection and quantification of viable B. dendrobatidis zoospores. The results show that the nucleic acid stains SYBR 14 and propidium iodide are effective in distinguishing live from dead zoospores, and a protocol has been optimized for their use. This viability assay provides an efficient and reliable tool that will have applications in B. dendrobatidis challenge and amphibian exposure experiments.

Malaria is a major cause of under-five mortality in Mali and many other developing countries. Malaria control programmes rely on households to identify sick children and either care for them in the home or seek treatment at a health facility in the case of severe illness. This study examines the involvement of mothers and other household members in identifying and treating severely ill children through case studies of 25 rural Malian households. A wide range of intra-household responses to severe illness were observed among household members, both exemplifying and contravening stated social norms about household roles. Given their close contact with children, mothers were frequently the first to identify illness symptoms. However, decisions about care-seeking were often taken by fathers and senior members of the household. As stewards of the family resources, fathers usually paid for care and thus significantly determined when and where treatment was sought. Grandparents were frequently involved in diagnosing illnesses and directing care towards traditional healers or health facilities. Relationships between household members during the illness episode were found to vary from highly collaborative to highly conflictive, with critical effects on how quickly and from where treatment for sick children was sought. These findings have implications for the design and targeting of malaria and child survival programming in the greater West African region.

Prior reports focus primarily on muscle fatty infiltration in Duchenne muscular dystrophy (DMD). However, the significance of muscle edema is uncertain. To evaluate the frequency and degree of muscle fat and edema, and correlate these with clinical function. Forty-two boys (ages 5-19 years) with DMD underwent pelvic MRI. Axial T1- and fat-suppressed T2-weighted images were evaluated to grade muscle fatty infiltration (0-4) and edema (0-3), respectively. Degree and frequency of disease involvement were compared to clinical evaluations. Gluteus maximus had the greatest mean fatty infiltration score, followed by adductor magnus and gluteus medius muscles, and had the most frequent and greatest degree of fatty infiltration. Gluteus maximus also had the greatest mean edema score, followed by vastus lateralis and gluteus medius muscles. These muscles had the most frequent edema, although the greatest degree of edema was seen in other muscles. There was correlation between cumulative scores of fatty infiltration and all clinical evaluations (P < 0.05). In DMD, the muscles with the most frequent fatty infiltration had the greatest degree of fatty infiltration and correlated with patient function. However, the muscles with the most frequent edema were different from those with the greatest degree of edema. Thus, edema may not predict patient functional status.

Pulmonary hemorrhage (PH) in systemic lupus erythematosus (SLE) is a rare but potentially fatal complication that occurs most frequently in the context of active lupus with involvement of other organs. The objective of this study is to report the clinical features and prognosis of patients with SLE who had PH. Patients with SLE (1982 American College of Rheumatology criteria) and PH under monitoring between June 1999 and November 2011 were studied. Demographic, clinical, laboratory, treatment and prognosis data related to PH were analyzed. Eleven patients with SLE developed 14 episodes of PH. PH was the first manifestation of SLE in 2 patients. The most frequent symptoms and clinical signs were dyspnea, fever and cough, which occurred in 12 (85%), 11 (77%) and 7 (50%) patients, respectively. Hemoptysis was also observed in 5 (35%) episodes, tachycardia in 2 (14%), pallor in one (7%) and chest pain in one (7%). All patients had other concomitant organ involvement, and were treated with glucocorticoids. In addition, intravenous cyclophosphamide was indicated in 12 episodes and plasma exchange in 4. Overall mortality was 64%. Factors associated with mortality were infection, mechanical ventilation and dialysis. PH continues to be a rare and severe complication of SLE. Its suspected presence forces us to quickly study these patients, since early diagnosis and aggressive treatment have been shown to improve survival in them. Copyright © 2014 Elsevier España, S.L.U.

Adverse reaction to food has increased around the world in last years. Prevalence of food allergy raises between 2-4% in adults, and 6-8% in children. The clinical presentation is heterogeneous and varies from mild symptoms to anaphylactic reactions. Even the clinical history focused in the food is important; demonstration of allergen sensitization is mandatory. To describe the profile of the patients with suspicion of food allergy and the regular clinical practice followed in Mexico. An observational, descriptive, cross-sectional study was carried out from March 2013 to March 2014 using a convenience sample of allergic patients who were treated in the office, both private and public, of those physicians who seen food allergy patients. Clinical, epidemiological, diagnostic and therapeutic data were collected from 1,971 suspicious food allergic patients presenting for the first time in the departments of the researchers involved in the study. No difference was found in relation to gender. In relation to age, a bimodal distribution, with peaks at 2 and 35 years old, was found. A history of respiratory allergy was present in 75% of cases; 80% of patients had had any previous symptoms before seeking consultation and the most frequent clinical manifestations were cutaneous, 5% reported anaphylaxis. The foods involved in reactions change with age. The clinical presentation changes with the food, although the skin is the most frequently affected organ. Even if the suspicious were high, the confirmation with specific diagnostic tools is strongly recommended.

The accuracy of references and quotations used to substantiate statements of fact in articles published in 6 frequently cited veterinary journals was examined. Three hundred references were randomly selected, and the accuracy of each citation was examined. A subset of 100 references was examined for quotational accuracy; ie, the accuracy with which authors represented the work or assertions of the author being cited. Of the 300 references selected, 295 were located, and 125 major errors were found in 88 (29.8%) of them. Sixty-seven (53.6%) major errors were found involving authors, 12 (9.6%) involved the article title, 14 (11.2%) involved the book or journal title, and 32 (25.6%) involved the volume number, date, or page numbers. Sixty-eight minor errors were detected. The accuracy of 111 quotations from 95 citations in 65 articles was examined. Nine quotations were technical and not classified, 86 (84.3%) were classified as correct, 2 (1.9%) contained minor misquotations, and 14 (13.7%) contained major misquotations. We concluded that misquotations and errors in citations occur frequently in veterinary journals, but at a rate similar to that reported for other biomedical journals.

Abstract To determine the prevalence of antineutrophil cytoplasmic antibodies (ANCA) in patients with infective endocarditis (IE) in internal medicine; and to compare clinical and biochemical features and outcome between patients exhibiting IE with and without ANCA. Fifty consecutive patients with IE underwent ANCA testing. The medical records of these patients were reviewed. Of the 50 patients with IE, 12 exhibited ANCA (24%). ANCA-positive patients with IE exhibited: longer duration between the onset of first symptoms and IE diagnosis (P = 0.02); and more frequently: weight loss (P = 0.017) and renal impairment (P = 0.08), lower levels of C-reactive protein (P = 0.0009) and serum albumin (P = 0.0032), involvement of both aortic and mitral valves (P = 0.009), and longer hospital stay (P = 0.016). Under multivariate analysis, significant factors for ANCA-associated IE were: longer hospital stay (P = 0.004), lower level of serum albumin (P = 0.02), and multiple valve involvement (P = 0.04). Mortality rate was 25% in ANCA patients; death was because of IE complications in all these patients. Our study identifies a high prevalence of ANCA in unselected patients with IE in internal medicine (24%). Our findings further underscore that ANCA may be associated with a subacute form of IE leading to multiple valve involvement and more frequent renal impairment. Because death was due to IE complications in all patients, our data suggest that aggressive therapy may be required to improve such patients’ outcome. PMID:26817911

To discuss pediatric clothing hanger injuries and review the National Electronic Injury Surveillance System to elucidate frequency and promote increased public awareness among pediatric otolaryngologists. Cross-sectional analysis of a national database. National Electronic Injury Surveillance System Database. A retrospective review of the National Electronic Injury Surveillance System provided a nationally weighted sampling estimate of 394 pediatric incident reports involving clothing hangers. Each incident report was analyzed for impalement, facial laceration, and contusion injuries to the mouth, face, and head. In addition, hospital disposition and location of the described incident were also obtained. Upon review of the National Electronic Injury Surveillance System, incident rates of pediatric oral impalement (95% confidence interval [CI], 0.10-0.41), facial laceration (95% CI, 0.22-0.41), and facial abrasion injuries (95% CI, 0.15-0.44) frequently involved the metal clothing hanger design. In addition, most of the reported injuries occurred within the home and involved lacerations to the oral cavity. This is the first multiyear, nationally representative study to analyze clothing hanger injuries in the pediatric population. We demonstrate that these injuries occur more frequently than the medical literature currently reports and also elucidate that children are more likely to obtain laceration injuries by metal clothing hangers within the home. Furthermore, we provide a recommendation for standardization of the National Electronic Injury Surveillance System such that product safety analysis may occur and reduce further pediatric incidents.

Dietary Behaviours, Impulsivity and Food Involvement: Identification of Three Consumer Segments.

This study aims to (1) identify consumer segments based on consumers' impulsivity and level of food involvement, and (2) examine the dietary behaviours of each consumer segment. An Internet-based cross-sectional survey was conducted among 530 respondents. The mean age of the participants was 49.2 ± 16.6 years, and 27% were tertiary educated. Two-stage cluster analysis revealed three distinct segments; "impulsive, involved" (33.4%), "rational, health conscious" (39.2%), and "uninvolved" (27.4%). The "impulsive, involved" segment was characterised by higher levels of impulsivity and food involvement (importance of food) compared to the other two segments. This segment also reported significantly more frequent consumption of fast foods, takeaways, convenience meals, salted snacks and use of ready-made sauces and mixes in cooking compared to the "rational, health conscious" consumers. They also reported higher frequency of preparing meals at home, cooking from scratch, using ready-made sauces and mixes in cooking and higher vegetable consumption compared to the "uninvolved" consumers. The findings show the need for customised approaches to the communication and promotion of healthy eating habits.

Cognitive screening tests frequently rely on items being correctly heard or seen. We aimed to identify, describe, and evaluate the adaptation, validity, and availability of cognitive screening and assessment tools for dementia which have been developed or adapted for adults with acquired hearing and/or vision impairment. Electronic databases were searched using subject terms "hearing disorders" OR "vision disorders" AND "cognitive assessment," supplemented by exploring reference lists of included papers and via consultation with health professionals to identify additional literature. 1,551 papers were identified, of which 13 met inclusion criteria. Four papers related to tests adapted for hearing impairment; 11 papers related to tests adapted for vision impairment. Frequently adapted tests were the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MOCA). Adaptations for hearing impairment involved deleting or creating written versions for hearing-dependent items. Adaptations for vision impairment involved deleting vision-dependent items or spoken/tactile versions of visual tasks. No study reported validity of the test in relation to detection of dementia in people with hearing/vision impairment. Item deletion had a negative impact on the psychometric properties of the test. While attempts have been made to adapt cognitive tests for people with acquired hearing and/or vision impairment, the primary limitation of these adaptations is that their validity in accurately detecting dementia among those with acquired hearing or vision impairment is yet to be established. It is likely that the sensitivity and specificity of the adapted versions are poorer than the original, especially if the adaptation involved item deletion. One solution would involve item substitution in an alternative sensory modality followed by re-validation of the adapted test.

Thymine kinase 2 (TK2) is a mitochondrial matrix protein encoded in nuclear DNA and phosphorylates the pyrimidine nucleosides: thymidine and deoxycytidine. Autosomal recessive TK2 mutations cause a spectrum of disease from infantile onset to adult onset manifesting primarily as myopathy. To perform a retrospective natural history study of a large cohort of patients with TK2 deficiency. The study was conducted by 42 investigators across 31 academic medical centres. We identified 92 patients with genetically confirmed diagnoses of TK2 deficiency: 67 from literature review and 25 unreported cases. Based on clinical and molecular genetics findings, we recognised three phenotypes with divergent survival: (1) infantile-onset myopathy (42.4%) with severe mitochondrial DNA (mtDNA) depletion, frequent neurological involvement and rapid progression to early mortality (median post-onset survival (POS) 1.00, CI 0.58 to 2.33 years); (2) childhood-onset myopathy (40.2%) with mtDNA depletion, moderate-to-severe progression of generalised weakness and median POS at least 13 years; and (3) late-onset myopathy (17.4%) with mild limb weakness at onset and slow progression to respiratory insufficiency with median POS of 23 years. Ophthalmoparesis and facial weakness are frequent in adults. Muscle biopsies show multiple mtDNA deletions often with mtDNA depletion. In TK2 deficiency, age at onset, rate of weakness progression and POS are important variables that define three clinical subtypes. Nervous system involvement often complicates the clinical course of the infantile-onset form while extraocular muscle and facial involvement are characteristic of the late-onset form. Our observations provide essential information for planning future clinical trials in this disorder. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2018-05-01

 Both dogs and bicycles are common in our society and thus a dog-bicycle interaction resulting in an injury to a cyclist is possible. It was the purpose of this study to investigate such injuries.  The National Electronic Injury Surveillance System (NEISS) data for the 10-year period from 2006 through 2015 associated with bicycles were accessed. Injuries involving dogs were identified and the mechanism of injury determined. Due to the stratified and weighted nature of the NEISS data, statistical analyses were performed with SUDAAN 10 software (RTI International, Research Triangle Park, North Carolina, United States). A p  < 0.05 was considered statistically significant.  There were 5,184,057 emergency department visits for bicycle-associated injuries; dogs were involved in 35,254 (0.67%) cases. The average age for those involved with a dog was 33.2 years and it was 25.5 years for those in which dogs were not involved. There were more females in the dog group (34.1 vs. 27.6%). Dog involvement increased from ages 0 to 14 years, then decreased until the age of 20 years and then progressively increased. Dog-associated injuries most frequently occurred away from home, involved the knee and distal lower extremity, 49.1% sustaining dog bites. Dog bites were more common in younger individuals. Four injury mechanisms (chased by a dog, hit/collided with a dog, swerved/tried to avoid a dog or riding with a dog) accounted for 97.5% of the injuries. Those chased by a dog were younger, more commonly released from the emergency department, had an injury involving the lower extremity and frequently sustained a bite. The most severe injuries were in those who swerved/tried to avoid a dog or hit a dog.  Approximately 1% of injuries to bicyclists are associated with dogs; one-half sustained a bite. Potential/proposed prevention strategies could be educational materials regarding bicycles and dogs to owners, dog restraint, student/parent education and educational materials in waiting rooms of veterinarians, paediatricians, family practice physicians and emergency rooms.

1987-07-01

To assess the effectiveness of child-resistant closures (CRCs) and unit dose packaging in preventing childhood poisoning with medications, a survey by 14 hospitals of accidental suspected poisoning in children under 5-years-old, was compared with a survey of a representative sample of households with children under 5 living in the catchment areas of the hospitals. Nine hundred and thirty-eight medications thought to have been ingested by 877 children were compared with 5827 medications found in households with children. The relationship between availability of packs or medications in the home and their involvement in accidents was quantified by means of an Accident Association Index (AAI). A low AAI indicated that the involvement of a pack or medication was less than expected from availability and therefore safe. A high AAI indicated that involvement was greater than expected and therefore unsafe. Medications involved in suspected poisoning were most frequently packed in containers without CRCs (63%) or transparent blisters (20%); both had high AAIs. CRCs, strips, sachets and opaque blisters had low AAIs. Analgesics, expectorants and gastrointestinal medications, had low AAIs, while oral contraceptives, hypnotics, sedative/tranquillizers, antidepressants, anticonvulsants, anti-emetics, and anti-infectives had high AAIs. Prescription medications were more frequently involved in accidents than over-the-counter (OTC) medications and had a higher AAI. Comparison of the AAIs of different kinds of medication in each of their various pack types showed that safe packaging reduced the risk from medications which had a high average AAI. Only 40% of medications were in their normal storage place at the time of the accident. Medicine and bathroom cabinets, and kitchen cupboards and drawers were the safest places to store medications. Handbags, fridges, and shelves or ledges in the bathroom were the most unsafe places. No pack had a low AAI when stored on open shelves indicating that safe packaging cannot compensate for unsafe storage. Other factors which influenced the involvement of medications in accidents were the intended user and the duration of storage. The results of the study have important implications for design of packaging for medications and for education of the public.

Differing patterns of neurophysiological abnormalities have been reported in patients with Fisher syndrome. Fisher syndrome is rare, and few series have incorporated prospective serial studies to define the natural history of nerve conduction studies in Guillain-Barré syndrome. In an ongoing prospective study of Guillain-Barré syndrome patients, patients who presented with Fisher syndrome and its spectrum of illness were assessed through serial neurological examinations, nerve conduction studies, and serological testing of IgG against gangliosides and ganglioside complexes. Of the 36 Guillain-Barré syndrome patients identified within 2 years, 17 had features of Fisher syndrome. Serial nerve conduction studies detected significant abnormalities in sensory nerve action potential amplitude in 94% of patients associated with 2 patterns of recovery-non-demyelinating reversible distal conduction failure and axonal regeneration. Similar changes were seen in motor nerves of 5 patients. Patients with the Fisher syndrome spectrum of illness have significant sensory involvement, which may only be evident with serial neurophysiological studies. Copyright © 2013 Wiley Periodicals, Inc.

The objective of the present study was to elucidate the specific features of the lesions of the cervical spine in the driver and the front-seat passenger of a modern car after the frontal crash. We made use of the archival materials of forensic medical expertises concerning the traffic accidents carried out in the city of Moscow during the period from 2005 to 2012. The study was focused on the analysis of the character of the fractures of cervical vertebrae in the drivers (n = 55) and the front-seat passengers (n = 85) of a modern motor vehicle involved in a traffic accident. It was shown that the drivers most frequently suffer bending-extension fractures of the cervical vertebrae, with the II-IV vertebrae being especially frequently subject to multiple fractures resulting in the damage to the anterior support column, sometimes to both the anterior and posterior columns, and much rarer to the posterior column. The front-seat passengers also suffer bending-extension fractures. The IV-VI vertebrae are most frequently affected in them with isolated damages to either the anterior or the posterior support column of the neck vertebrae.

To evaluate the hand hygiene (HH) practices among veterinary technicians (VT) and veterinary support staff (VSS) in small animal private practice. This was a prospective questionnaire-based study involving 182 VT and VSS from 18 small animal hospitals in the USA. Questions asked included gender, number of animals handled per work shift, frequency of hand washing, reason for not washing more frequently, most common available hand washing agent, education regarding the importance of HH and frequency of ring wearing. Less than half of the respondents [76 of 182 (41·7%)] reported washing their hands regularly between handling patients and 154 of 182 (85·6%) believed they should have washed more frequently. The most commonly employed HH agent was hand soap [154 of 182 (84·6%)] and the most common reason cited for not washing more frequently was being too busy [132 of 182 (72·5%)]. Only 96 of 182 (52·7%) respondents were educated by doctors at their hospital regarding the importance of HH. The HH practices among VT and VSS in small animal private practice is poor. Hand soap was the most commonly employed agent among respondents in this study. Education of VT and VSS regarding the importance of HH requires improvement. © 2012 British Small Animal Veterinary Association.

The objectives of this study were: 1) to identify the ultrasonographic (US) abnormalities and 2) to compare the findings of physical examination with US findings in rheumatoid arthritis (RA) patients with shoulder pain. We studied 30 RA patients. Physical examination was performed systemically as follows: 1) area of tenderness; 2) range of passive and active shoulder motion; 3) impingement tests; 4) maneuvers for determining the location of the tendon lesions. US investigations included the biceps, the supraspinatus, infraspinatus, and subscapularis tendons; the subacromial-subdeltoid bursa; and the glenohumeral and acromioclavicular joints. Thirty RA patients with 35 painful and 25 non-painful shoulders were examined. The range of motion affected the most by shoulder pain was abduction. The most frequent US finding of shoulder joint was effusion in the long head of the biceps tendon. Among the rotator cuff tendons, subscapularis was the most frequently involved. Tendon tear was also common among non-painful shoulders. Physical examination used for the diagnosis of shoulder pain had low sensitivity and specificity for detecting abnormalities in the rheumatoid shoulder joint. In conclusion, US abnormalities showed frequent tendon tears in our RA patients. Physical examination had low sensitivity and specificity for detecting rotator cuff tear in the rheumatoid shoulder joint. PMID:17728506

Abstract Vascular involvement can be seen in up to 40% of patients with Behcet syndrome (BS), the lower-extremity vein thrombosis (LEVT) being the most common type. The aim of the current study was to compare venous Doppler findings and clinical features between BS patients with LEVT and control patients diagnosed as having LEVT due to other causes. All consecutive 78 patients (71 men, 7 women; mean age 38.6 ± 10.3 years) with LEVT due to BS and 50 control patients (29 men, 21 women; mean age 42.0 ± 12.5 years) who had LEVT due to other causes, or idiopathic, were studied with the help of a Doppler ultrasonography after a detailed clinical examination. Patterns of venous disease were identified by cluster analyses. Clinical features of chronic venous disease were assessed using 2 classification systems. Venous claudication was also assessed. Patients with BS were more likely to be men, had significantly earlier age of onset of thrombosis, and were treated mainly with immunosuppressives and less frequently with anticoagulants. Furthermore, they had significantly more bilateral involvement, less complete recanalization, and more frequent collateral formation. While control patients had a disorganized pattern of venous involvement, BS patients had a contiguous and symmetric pattern, involving all deep and superficial veins of the lower extremities, with less affinity for crural veins. Clinical assessment, as measured by the 2 classification systems, also indicated a more severe disease among the BS patients. In line, 51% of the BS patients suffered from severe post-thrombotic syndrome (PTS) and 32% from venous claudication, whereas these were present in 8% and 12%, respectively, among the controls. Among BS patients, a longer duration of thrombosis, bilateral femoral vein involvement, and using no anticoagulation along with immunosuppressive treatment when first diagnosed were found to be associated independently with severe PTS. Lower-extremity vein thrombosis associated with BS, when compared to LEVT due to other causes, had distinctive demographic and ultrasonographic characteristics, and had clinically a more severe disease course.

2015-01-01

The blastoid variant of mantle cell lymphoma (MCL), which accounts for less than one-third of MCL, may arise de novo or as a transformation from the classical form of MCL. Blastoid variant, which predominantly involves men in their sixth decade, has frequent extranodal involvement (40-60%), stage IV disease (up to 85%) and central nervous system (CNS) involvement. Diagnosis relies on morphological features and is challenging. Immunophenotyping may display CD23 and CD10 positivity and CD5 negativity in a subset. Genetic analysis demonstrates an increased number of complex genetic alterations. Blastoid variant responds poorly to conventional chemotherapy and has a short duration of response. Although the optimal therapy remains to be established, CNS prophylaxis and the use of aggressive immunochemotherapy followed by autologous stem cell transplant may prolong the remission rate and survival. Further studies are crucial to expand our understanding of this disease entity and improve the clinical outcome.

Religious Denomination, Religious Involvement, and Modern Contraceptive Use in Southern Mozambique

PubMed Central

Agadjanian, Victor

2015-01-01

The relationship between contraceptive use and religion remains a subject of considerable debate. This article argues that this relationship is rooted in context-specific institutional and organizational aspects of religious belonging and involvement. Drawing upon unique recent data from a population-based survey of women conducted in a predominantly Christian high-fertility area of Mozambique, this study examines the connections between religion and contraception from two complementary angles. First, differences in current use of modern contraceptives across main denominational groups are analyzed. The results show higher prevalence of modern contraceptive use among Catholics and, to a lesser extent, traditional Protestants net of other individual- and community-level factors. Second, an analysis of religious involvement reveals that frequent church attendance has a net positive association with modern contraceptive use regardless of denominational affiliation. These findings are situated within the historical context of religious, demographic, and socio-political dynamics of Mozambique and similar sub-Saharan settings. PMID:24006073

Early print-tuned ERP response with minimal involvement of linguistic processing in Japanese Hiragana strings.

PubMed

2014-04-16

The act of reading leads to the development of specific neural responses for print, the most frequently reported of which is the left occipitotemporal N170 component of event-related potentials. However, it remains unclear whether this electrophysiological response solely involves print-tuned neural activities. The present study examined an early print-tuned event-related potential response with minimal involvement of linguistic processing in a nonalphabetic language. Japanese Hiragana words, nonwords, and alphanumeric symbol strings were presented rapidly and the task was to detect the change in color of a fixation cross to restrict linguistic processing. As a result, Hiragana words and nonwords elicited a larger posterior N1 than alphanumeric symbol strings bilaterally, irrespective of intercharacter spacing. The fact that this N1 was enhanced specifically for rapidly presented Hiragana strings suggests the existence of print-tuned neural processes that are relatively independent of the influence of linguistic processing.

To study the natural history and growth of optic nerve sheath meningiomas and evaluate their management outcome. Clinicopathologic retrospective noncomparative case series. A retrospective study of 88 patients who were treated between 1976 and 1999 at the University of British Columbia and the University of Amsterdam. Clinical reports, imaging studies, and histopathologic findings were reviewed. The mean age at onset of symptoms was 40.3 years, and most were seen in middle-aged females. Patients typically presented with visual loss, frequently associated with optic atrophy or papilledema and occasionally optociliary shunt vessels. On imaging, the optic nerve demonstrated segmental or diffuse thickening of the sheath or globular growth. Calcification was seen in 31% of cases and was associated with slower tumor growth. Tumors with posterior components in the orbit had more frequent intracranial involvement. Intracranial extension was more frequent and had a greater growth rate in younger patients. Irregular margins in the orbit implied local invasion. A presenting visual acuity better than 20/50 correlated with longer preservation of vision. Patients who underwent radiotherapy showed improvement in their visual acuity, and tumor growth was halted. Optic sheath decompression did not preserve vision. En bloc tumor excision was associated with no detectable recurrence in contrast to debulked tumors that recurred. Meningiomas show characteristic indolent growth. Management therefore should be conservative in most cases. Radiotherapy is indicated in patients with progressive visual deterioration. Surgery, when indicated, should be an en bloc excision.

AIM: To analyze the effect of bipolar electrocoagulation and argon plasma coagulation on fresh specimens of gastrointestinal tract. METHODS: An experimental evaluation was performed at Hospital das Clinicas of the University of São Paulo, on 31 fresh surgical specimens using argon plasma coagulation and bipolar electrocoagulation at different time intervals. The depth of tissue damage was histopathologically analyzed by single senior pathologist unaware of the coagulation method and power setting applied. To analyze the results, the mucosa was divided in superficial mucosa (epithelial layer of the esophagus and superficial portion of the glandular layer of the stomach and colon) intermediate mucosa (until the lamina propria of the esophagus and until the bottom of the glandular layer of the stomach and colon) and muscularis mucosa. Necrosis involvement of the layers was compared in several combinations of power and time interval. RESULTS: Involvement of the intermediate mucosa of the stomach and of the muscularis mucosa of the three organs was more frequent when higher amounts of energy were used with argon plasma. In the esophagus and in the colon, injury of the intermediate mucosa was frequent, even when small amounts of energy were used. The use of bipolar electrocoagulation resulted in more frequent involvement of the intermediate mucosa and of the muscularis mucosa of the esophagus and of the colon when higher amounts of energy were used. In the stomach, these involvements were rare. The risk of injury of the muscularis propria was significant only in the colon when argon plasma coagulation was employed. CONCLUSION: Tissue damage after argon plasma coagulation is deeper than bipolar electrocoagulation. Both of them depend on the amount of energy used. PMID:25031789

Introduction Despite the expected beneficial effects on quality of care, patient involvement in diabetes care groups, which deliver a bundled paid integrated care programme for diabetes type 2, seems to be limited. The aim of this study was to gain insight into levels and methods of patient involvement, into facilitators and barriers, and into the future preferences of care groups and patient representatives. Theory and methods Semi-structured interviews were held with 10 representatives of care groups and 11 representatives of patient advocacy groups. An adapted version of Arnstein's ladder of citizen participation was used to define five levels of patient involvement. Results Patient involvement in care groups was mostly limited to informing and consulting patients. Higher levels, i.e., advising, co-producing and decision-making, were less frequently observed. Care groups and patient representatives perceived largely the same barriers and facilitators and had similar preferences regarding future themes and design of patient involvement. Conclusion Constructive collaboration between diabetes care groups and patient representatives to enhance patient involvement in the future seems viable. Several issues such as the lack of evidence for effectiveness of patient involvement, differences in viewpoints on the role and responsibilities of care groups and perceived barriers need to be addressed.

Leukocyte Cell–Derived Chemotaxin 2–Associated Amyloidosis: A Recently Recognized Disease with Distinct Clinicopathologic Characteristics

PubMed Central

Dogan, Ahmet; Larsen, Christopher P.

2015-01-01

Amyloidosis derived from leukocyte cell–derived chemotaxin 2 is a recently recognized form of amyloidosis, and it has already been established as a frequent form of systemic amyloidosis in the United States, with predominant involvement of kidney and liver. The disease has a strong ethnic bias, affecting mainly Hispanics (particularly Mexicans). Additional ethnic groups prone to develop amyloidosis derived from leukocyte cell–derived chemotaxin 2 include Punjabis, First Nations people in British Columbia, and Native Americans. Most patients are elderly who present with chronic renal insufficiency and bland urinary sediment. Proteinuria is variable, being absent altogether in about one third of patients. Liver involvement is frequently an incidental finding. Amyloidosis derived from leukocyte cell–derived chemotaxin 2 deposits shows a characteristic distribution: in the kidney, there is consistent involvement of cortical interstitium, whereas in the liver, there is a preferential involvement of periportal and pericentral vein regions. Concurrent renal disease is frequent, with diabetic nephropathy and IgA nephropathy being the most common. Patient survival is excellent, likely because of the rarity of cardiac involvement, whereas renal survival is guarded, with a median renal survival of 62 months in those without concurrent renal disease. There is currently no efficacious therapy for amyloidosis derived from leukocyte cell–derived chemotaxin 2 amyloidosis. Renal transplantation seems to be a reasonable treatment for patients with advanced renal failure, although the disease may recur in the allograft. The pathogenesis of amyloidosis derived from leukocyte cell–derived chemotaxin 2 amyloidosis has not yet been elucidated. It could be a result of leukocyte cell–derived chemotaxin 2 overexpression by hepatocytes either constitutively (controlled by yet-uncharacterized genetic defects) or secondary to hepatocellular damage. It is critical not to misdiagnose amyloidosis derived from leukocyte cell–derived chemotaxin 2 amyloidosis as Ig light chain–derived amyloidosis to avoid harmful chemotherapy. PMID:25873265

The present investigation involved a systematic literature review to (1) identify associations between personality constructs and unprotected sex among people living with HIV/AIDS (PLWH); (2) assess patterns of direct versus indirect personality-risky sex associations; and (3) explore possible differences in personality-risky sex associations among PLWH versus non-infected populations. Among the 26 studies yielded through the systematic search, sensation seeking and sexual compulsivity were the constructs most frequently examined, with fewer studies investigating traditional personality typologies. Personality constructs that were more conceptually proximal to the sexual act, such as sexual compulsivity and sex-related sub-components of sensation seeking, showed relatively direct associations with unprotected sex, whereas more conceptually distal constructs such as generalized impulsivity demonstrated only weak or indirect associations. Associations were also frequently mediated by other risk factors, including perceived responsibility and substance use. These findings have implications for the development of interventions to reduce high risk sexual behavior among PLWH.

To describe the profile of patients treated in the trauma and orthopedics nursing of a trauma care referral public hospital of in the state of Bahia. Cross-sectional study in which data were collected from medical records of patients in the period from July to December 2008. The profile of the patients involved was formed by subjects mostly male young subjects, victims of trauma from accidents, especially those with motorcycles or car runover. On the other hand,the most frequent traumas associated with urban violence were perforations by gunshot and stab wounds. The primary injury presented by these individuals was exposed fracture of the femur and the most common treatment was external fixation. The most frequent in-hospital complication was wound infection, which required another surgical approach. Most inpatients were discharged and only one death was reported during this period. The results of this study corroborate those from other institutions in the country, which may contribute to elaborate public policies for accidents and violence prevention.

Although mucocutaneous sites are the most frequently encountered sites of involvement, Kaposi Sarcoma (KS) may also occasionally involve the breast and the skeletal, endocrine, urinary and nervous systems.. Various imaging modalities may be used to delineate the extent of the disease by detecting unexpected sites of involvement. Herein, we report a case of classical type KS, in whom staging with (18)F-FDG PET/CT imaging disclosed widespread disease and unexpected findings of bone and salivary gland involvement.

The major changes to our world are those involving the atmosphere and the climate, including global warming induced by anthropogenic factors, with impact on the biosphere and human environment. Studies on the effects of climate changes on respiratory allergy are still lacking and current knowledge is provided by epidemiological and experimental studies on the relationship between allergic respiratory diseases, asthma and environmental factors, like meteorological variables, airborne allergens and air pollution. Epidemiologic studies have demonstrated that urbanization, high levels of vehicle emissions and westernized lifestyle are correlated with an increased frequency of respiratory allergy, mainly in people who live in urban areas in comparison with people living in rural areas. However, it is not easy to evaluate the impact of climate changes and air pollution on the prevalence of asthma in general and on the timing of asthma exacerbations, although the global rise in asthma prevalence and severity could be also considered an effect of air pollution and climate changes. Since airborne allergens and air pollutants are frequently increased contemporaneously in the atmosphere, enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of respiratory allergy and asthma in atopic subjects in the last five decades. Pollen allergy is frequently used to study the interrelationship between air pollution and respiratory allergic diseases such as rhinitis and bronchial asthma. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. Scientific societies should be involved in advocacy activities, such as those realized by the Global Alliance against chronic Respiratory Diseases (GARD).

Perceptions of Teaching Methods for Preclinical Oral Surgery: A Comparison with Learning Styles

PubMed Central

Omar, Esam

Purpose: Dental extraction is a routine part of clinical dental practice. For this reason, understanding the way how students’ extraction knowledge and skills development are important. Problem Statement and Objectives: To date, there is no accredited statement about the most effective method for the teaching of exodontia to dental students. Students have different abilities and preferences regarding how they learn and process information. This is defined as learning style. In this study, the effectiveness of active learning in the teaching of preclinical oral surgery was examined. The personality type of the groups involved in this study was determined, and the possible effect of personality type on learning style was investigated. Method: This study was undertaken over five years from 2011 to 2015. The sample consisted of 115 students and eight staff members. Questionnaires were submitted by 68 students and all eight staff members involved. Three measures were used in the study: The Index of Learning Styles (Felder and Soloman, 1991), the Myers-Briggs Type Indicator (MBTI), and the styles of learning typology (Grasha and Hruska-Riechmann). Results and Discussion: Findings indicated that demonstration and minimal clinical exposure give students personal validation. Frequent feedback on their work is strongly indicated to build the cognitive, psychomotor, and interpersonal skills needed from preclinical oral surgery courses. Conclusion: Small group cooperative active learning in the form of demonstration and minimal clinical exposure that gives frequent feedback and students’ personal validation on their work is strongly indicated to build the skills needed for preclinical oral surgery courses.

Previous research has suggested a link between athletic involvement and elevated levels of adolescent violence outside the sport context. The present study expanded on this literature by positing differences in the sport-violence relationship across dimensions of athletic involvement (athletic participation vs. jock identity), type of violence (family vs. nonfamily), and gender as well as by examining the impact of binge drinking on the sport-violence relationship. Regression analyses using a sample of 608 Western New York adolescents indicated that (a) jock identity (but not athletic participation) was associated with more frequent violence, (b) jock identity predicted nonfamily violence (but not family violence), and (c) the link between jock identity and nonfamily violence was stronger for boys than for girls. Binge drinking predicted family violence among nonjocks only.

Changes in nailfold capillaroscopy in systemic sclerosis patients could be related to the disease severity. The aim of this study was to investigate whether patients with "late" scleroderma (SD) pattern have more organ involvement than patients with "early/active" SD pattern. Forty-six Argentinian patients (44 women and 2 men), with a diagnosis of systemic sclerosis, were distributed in two groups based on the presence of late and early/active patterns. Organ involvement was assessed as follows: pulmonary function by chest radiography, high-resolution chest tomography (HRCT), lung volume tests, and diffusing capacity for carbon monoxide (DLCO); esophageal involvement by manometry; and pulmonary arterial hypertension (PAH) by Doppler echocardiography and six-minute walk test. Honeycombing of the lungs evaluated by HRCT was more frequently present in patients with late pattern compared with early/active patients (p = 0.01). We also found statistically significant differences in lung volume tests (p = 0.03) and DLCO (p = 0.02) between the two SD pattern groups. Esophageal manometry showed a significantly higher frequency of motility disorders in the group with late pattern (p = 0.0024). In this study, patients with late pattern had higher frequency of pulmonary and esophageal involvement compared with patients with early/active pattern.

[Management of somatization in depression].

Management of somatization in depression depends on understanding its mechanisms. This kind of somatization is the product of both specific and nonspecific factors which interact to create a chronic and hypocondriacal picture. Biological treatment looks like treatment of chronic depression. Antidepressants with anxiolytic properties have a place of choice. Psychotherapy is frequently used, particularly cognitive behavior therapy which allows the reattribution of somatic symptoms to psychological events. General practitioners need to be trained to these techniques as they are, more frequently than psychiatrists, involved in the management of these patients.

Genetic polymorphism in three glutathione s-transferase genes and breast cancer risk

DOE Office of Scientific and Technical Information (OSTI.GOV)

Woldegiorgis, S.; Ahmed, R.C.; Zhen, Y.

The role of the glutathione S-transferase (GST) enzyme family is to detoxify environmental toxins and carcinogens and to protect organisms from their adverse effects, including cancer. The genes GSTM1, GSTP1, and GSTT1 code for three GSTs involved in the detoxification of carcinogens, such as polycyclic aromatic hydrocarbons (PAHs) and benzene. In humans, GSTM1 is deleted in about 50% of the population, GSTT1 is absent in about 20%, whereas the GSTP1 gene has a single base polymorphism resulting in an enzyme with reduced activity. Epidemiological studies indicate that GST polymorphisms increase the level of carcinogen-induced DNA damage and several studies havemore » found a correlation of polymorphisms in one of the GST genes and an increased risk for certain cancers. We examined the role of polymorphisms in genes coding for these three GST enzymes in breast cancer. A breast tissue collection consisting of specimens of breast cancer patients and non-cancer controls was analyzed by polymerase chain reaction (PCR) for the presence or absence of the GSTM1 and GSTT1 genes and for GSTP1 single base polymorphism by PCR/RFLP. We found that GSTM1 and GSTT1 deletions occurred more frequently in cases than in controls, and GSTP1 polymorphism was more frequent in controls. The effective detoxifier (putative low-risk) genotype (defined as presence of both GSTM1 and GSTT1 genes and GSTP1 wild type) was less frequent in cases than controls (16% vs. 23%, respectively). The poor detoxifier (putative high-risk) genotype was more frequent in cases than controls. However, the sample size of this study was too small to provide conclusive results.« less

Frequent ultraviolet brightenings observed in a solar active region with solar maximum mission

Porter, J. G.; Toomre, J.; Gebbie, K. B.

1984-01-01

Observations of the temporal behavior of ultraviolet emission from bright points within an active region of the sun are reported. Frequent and rapid brightenings in Si IV and O IV line emission are seen. The observations suggest that intermittent heating events of modest amplitude are occurring at many sites within an active region. By selecting the brightest site at any given time within an active region and then sampling its behavior in detail within a 120 s interval, it is found that about two-thirds of the samples show variations of the Si IV line intensity. The brightenings typically last about 40-60 s; intensity increases of about 20-100 percent are frequently observed. The results suggest that heating due to magnetic field reconnection within an active region is proceeding almost stochastically. Events involving only a modest release of energy occur the most frequently.

Aligning the Cultures of Teaching and Learning Science in Urban High Schools

Tobin, Kenneth

2006-09-01

This paper analyzes teaching and learning in urban science classrooms in which most of the students are African American and from low-income homes. Their teachers are also racial minorities and yet they struggle to teach successfully across cultural boundaries. The first set of case studies involves a male teacher who taught in a high-energy way that produced structures for students to get involved in the doing of science. His verbal fluency and expressive individualism, involving emphatic gestures, rhythmic use of his body, and voice intonation maintained student participation. A second case study examines successful interactions among the students, involving an argument over competing models for chemical valence. Whereas the students interacted successfully, the teacher was frequently out of synchrony in terms of amplitude, pitch, and non-verbal actions. The key implication is the necessity for teachers and students to learn how to interact successfully in ways that produce positive emotional energy, a sense of belonging to the class, and a commitment to shared responsibility for one another's participation. Aligning the cultures of teaching and learning offers a possibility that fluent interactions will occur, afford success, and facilitate the learning of science.

Lung Involvement in Systemic Sclerosis

PubMed Central

Hassoun, Paul M.

2011-01-01

Summary Scleroderma is a multisystem disease characterized by a severe inflammatory process and exuberant fibrosis. Lung involvement is a frequent complication and a leading cause of morbidity and mortality in this syndrome. Two major pulmonary syndromes are associated with scleroderma; a pulmonary vascular disorder evolving over time into relatively isolated pulmonary arterial hypertension (PAH), and interstitial lung disease (ILD). Each syndrome, when present, is a cause of morbidity and significantly reduces survival of scleroderma patients when compared to patients free of lung complication. When pulmonary hypertension and ILD are combined, survival is further reduced. Current therapy appears to have no meaningful effect on either condition and, thus, there is a need for better understanding of underlying pathogenic mechanisms. This review focuses on clinical, diagnostic, and therapeutic features of PAH and ILD as well as other frequent but less debilitating lung complications of scleroderma. PMID:21195581

The multiple genetic causes of central hypothyroidism.

PubMed

Persani, Luca; Bonomi, Marco

2017-03-01

An insufficient stimulation by thyrotropin (TSH) of an otherwise normal thyroid gland represents the cause of Central Hypothyrodism (CeH). CeH is about 1000-folds rarer than Primary Hypothyroidism and often represents a real challenge for the clinicians, mainly because they cannot rely on adequately sensitive parameters for diagnosis or management, as it occurs with circulating TSH in PH. Therefore, CeH diagnosis can be frequently missed or delayed in patients with a previously unknown pituitary involvement. A series of genetic defects have been described to account for isolated CeH or combined pituitary hormone defects (CPHDs) with variable clinical characteristics and degrees of severity. The recently identified candidate gene IGSF1 appears frequently involved. This review provides an updated illustration of the different genetic defects accounting for CeH.

[Many faces of sarcoidosis].

PubMed

Prosch, H; Vonbank, K; Loewe, C; Beitzke, D

2016-01-01

Sarcoidosis is a systemic, inflammatory, granulomatous disease of unknown origin that can involve any organ. More than 90% of patients have thoracic sarcoidosis, which most frequently presents with bilateral hilar lymphadenopathy. In approximately 20% of patients with thoracic sarcoidosis there is involvement of the lung parenchyma as well as mostly asymptomatic cardiac sarcoidosis in up to 55% of patients. Most patients are asymptomatic and the diagnosis is an incidental finding on chest X-ray or during clarification of unspecific symptoms, such as fatigue or cough. In approximately two thirds of patients the disease undergoes spontaneous remission and in one third the disease follows a chronic or even progressive course. Furthermore, sarcoidosis can also be manifested in the abdominal organs, the central nervous system (CNS) and the musculoskeletal system. These manifestations are frequently subclinical and require targeted diagnostics when sarcoidosis is clinically suspected.

Loss of heterozygosity (LOH) at 11q23-qter occurs frequently in ovarian and other cancers, but for colorectal cancer, the evidence is conflicting. Seven polymorphic loci were analyzed between D11S897 and D11S969 in 50 colorectal tumors. Two distinct LOH regions were detected, suggesting possible sites for tumor-suppressor genes involved in colorectal neoplasia: a large centromeric region between D11S897 and D11S925, and a telomeric 4.9-Mb region between D11S912 and D11S969. There was no correlation with clinicopathological features. This analysis describes a region of LOH in the region 11q23.3-24.3 for the first time in colorectal cancer and provides complementary evidence for the ongoing effort to identify the gene(s) involved.

The authors retrospectively evaluated 33 eye injuries due to metal missiles in 31 patients presenting to our emergency center over the last 3 years. Injuries occurred most frequently when the patients were grinding metal or working on their cars. The type of metal involved in the injury often dictates the type of ophthalmic reaction that will occur. A discussion of intraocular metallic foreign bodies with an emphasis on electroretinograms and metal analysis is presented.

2016-02-01

The prevalence of extraintestinal manifestations in inflammatory bowel diseases varies from 6% to 46%. The aetiology of extraintestinal manifestations remains unclear. There are theories based on an immunological response influenced by genetic factors. Extraintestinal manifestations can involve almost every organ system. They may originate from the same pathophysiological mechanism of intestinal disease, or as secondary complications of inflammatory bowel diseases, or autoimmune diseases susceptibility. The most frequently involved organs are the joints, skin, eyes, liver and biliary tract. Renal involvement has been considered as an extraintestinal manifestation and has been described in both Crohn's disease and ulcerative colitis. The most frequent renal involvements in patients with inflammatory bowel disease are nephrolithiasis, tubulointerstitial nephritis, glomerulonephritis and amyloidosis. The aim of this review is to evaluate and report the most important data in the literature on renal involvement in patients with inflammatory bowel disease. Bibliographical searches were performed of the MEDLINE electronic database from January 1998 to January 2015 with the following key words (all fields): (inflammatory bowel disease OR Crohn's disease OR ulcerative colitis) AND (kidney OR renal OR nephrotoxicity OR renal function OR kidney disease OR renal disease OR glomerulonephritis OR interstitial nephritis OR amyloidosis OR kidney failure OR renal failure) AND (5-aminosalicylic acid OR aminosalicylate OR mesalazine OR TNF-α inhibitors OR cyclosporine OR azathioprine OR drugs OR pediatric).

Duraplasty, a common neurosurgical intervention, involves synthetic or biological graft placement to ensure dural closure. The objective of this study is to advance our understanding of the use of dural substitutes in cranial surgery. The PubMed database was systematically searched to identify studies published over the past decade (2007-2017) that described duraplasty procedures. Clinical data were disaggregated and analyzed for the comparisons of biological versus synthetic grafts. A total of 462 cases were included in the quantitative synthesis. Overall, the most common indication for duraplasty was tumor resection (53%). Allografts were more frequently used in decompression for Chiari malformations compared with xenografts and synthetic grafts (P < 0.001). Xenografts were more frequently used in decompressive hemicraniectomy procedures for evacuation of acute subdural hematomas over allografts and synthetics (P < 0.001). Synthetic grafts were more frequently used in tumor cases than biological grafts (P = 0.002). The cumulative complication rate for dural substitutes of all types was 11%. There were no significant differences in complication rates among the 3 types of dural substitutes. Dural substitutes are commonly used to ensure dural closure in a variety of cranial procedures. This study provides greater insight into duraplasty practices and highlights the moderate complication rate associated with the procedure. Future studies are needed to determine the safety and efficacy of such procedures in larger prospective cohorts. Copyright © 2018. Published by Elsevier Inc.

The Vulnerability of People to Damaging Hydrogeological Events in the Calabria Region (Southern Italy)

2017-01-01

Background: Damaging Hydrogeological Events (DHEs) are severe weather periods during which floods, landslides, lightning, windstorms, hail or storm surges can harm people. Climate change is expected to increase the frequency/intensity of DHEs and, consequently, the potential harm to people. Method: We investigated the impacts of DHEs on people in Calabria (Italy) over 37 years (1980–2016). Data on 7288 people physically affected by DHEs were gathered from the systematic analysis of regional newspapers and collected in the database named PEOPLE. The damage was codified in three severity levels as follows: fatalities (people who were killed), injured (people who suffered physical harm) and involved (people who were present at the place where an accident occurred but survived and were not harmed). During the study period, we recorded 68 fatalities, 566 injured and 6654 people involved in the events. Results: Males were more frequently killed, injured and involved than females, and females who suffered fatalities were older than males who suffered fatalities, perhaps indicating that younger females tended to be more cautious than same-aged males, while older females showed an intrinsic greater vulnerability. Involved people were younger than injured people and fatalities, suggesting that younger people show greater promptness in reacting to dangerous situations. Floods caused the majority of the fatalities, injured and involved people, followed by landslides. Lightning was the most dangerous phenomenon, and it affected a relatively low number of people, killing 11.63% of them and causing injuries to 37.2%. Fatalities and injuries mainly occurred outdoors, largely along roads. In contrast, people indoors, essentially in public or private buildings, were more frequently involved without suffering harm. Being “dragged by water/mud” and “surrounded by water/mud”, respectively, represented the two extremes of dynamic dangerousness. The dragging effect of rapid-flowing water totally or partially obstructed the attempts of people to save their lives. In contrast, people surrounded by steady water/mud encountered difficulties but ultimately could survive. Conclusions: The study outcomes can be used in informational campaigns to increase risk awareness among both administrators and citizens and to improve community resilience, particularly in promoting self-protective behaviors and avoiding the underestimation of hazardous situations.

In this article, we examine the relationship between the total number of types of gambling that are legal in a state and the gambling involvement of state residents. Of particular interest is whether more types of legal gambling are associated with higher rates of problem gambling. Telephone surveys of U.S. adults were conducted in 1999-2000 and 2011-2013. The same questions were used and the data sets were combined for most of the analyses. Gambling exposure was defined as the sum of the number of years that all types were legal. Results tabulated by state showed progressively higher rates of problem gambling, frequent gambling and any past year gambling as the number of legal types of gambling increased. Holding constant the number of legal types, problem gambling rates increased as exposure increased. States with longer exposure to legal lotteries or casinos tended to have higher rates of problem gambling. An analysis was also conducted in which the data sets from 1999 to 2000 and from 2011 to 2013 were compared. Among the states, there was a striking positive relationship between changes in the number of legal types of gambling between the two studies and changes in rates of frequent gambling between the two studies. For states that had fewer types of legal gambling in 2011 than in 1999, the rates of frequent gambling went down. For states that increased their types of legal gambling, rates of frequent gambling typically, but not always, went up. Possible explanations for these results were discussed.

Food allergy affects around 6% of the European population and its prevalence worldwide has been increasing in the last decades, but studies focused on investigating food allergy epidemiology in Europe are lacking. The Cibus project was created to register the main culprit foods and their clinical manifestations in food allergic patients in Catalonia. A specific online database was designed. Allergists from eight different Catalan hospitals registered the new diagnoses of food allergy. 618 food allergic patients were included. Egg and milk were the main elicitors in the early ages, while fruits and nuts were the most frequent in patients >14 years old. Fish was more frequent in children, while seafood and Anisakis allergy were more frequent in the >14-year-old group. Overall, peach was the most prevalent food eliciting an allergic reaction (10%). Food allergy diagnosis was reached using compatible clinical history and positive skin prick test to the involved food in 98% of cases. Globally, urticaria was the most frequently reported manifestation in our population (48.2%), followed by oral allergy syndrome (25.6%) and anaphylaxis (24.8%). The Cibus project gives a full overview of the profile of food allergic patients in Catalonia and reinforces the predominance of plant food allergies in the Mediterranean area.

Self-reported and observed risky driving behaviors among frequent and infrequent cell phone users.

PubMed

Zhao, Nan; Reimer, Bryan; Mehler, Bruce; D'Ambrosio, Lisa A; Coughlin, Joseph F

2013-12-01

The apparently higher crash risk among individuals who use cell phones while driving may be due both to the direct interference of cell phone use with the driving task and tendencies to engage in risky driving behaviors independent of cell phone use. Measurements of actual highway driving performance, self-reported aberrant driving behaviors as measured by the Manchester Driver Behavior Questionnaire (DBQ), and attitudes toward speeding, passing behaviors and relative concern about being involved in a crash were assessed. Individuals who reported frequently using cell phones while driving were found to drive faster, change lanes more frequently, spend more time in the left lane, and engage in more instances of hard braking and high acceleration events. They also scored higher in self-reported driving violations on the DBQ and reported more positive attitudes toward speeding and passing than drivers who did not report using a cell phone regularly while driving. These results indicate that a greater reported frequency of cell phone use while driving is associated with a broader pattern of behaviors that are likely to increase the overall risk of crash involvement.

Previous studies have demonstrated that clusterin (CLU), which is also known as apolipoprotein J, is involved in the pathogenesis of Alzheimer disease (AD). In this study, we investigated the association between rs2279590, rs11136000, and rs9331888 single-nucleotide polymorphisms (SNPs) in CLU and apolipoprotein E (APOE) genotypes in a cohort of Turkish patients with late-onset AD (LOAD). There were 183 patients with LOAD and 154 healthy controls included in the study. The CLU and APOE polymorphisms were genotyped using the LightSNiP assay. The "GG" genotype of rs9331888 was significantly more frequent in patients with LOAD. The "CC" genotype of the SNP was significantly more frequent in controls. The rs9331888 "GG" genotype in patients and the "CC" genotype in controls were significantly higher in non-∊4 allele carriers of APOE The haplotype analysis showed the CLU "GCG" haplotype was a risk haplotype. Our findings indicate the rs9331888 SNP of CLU is associated with LOAD independent of APOE. © The Author(s) 2016.

Monotony of road environment and driver fatigue: a simulator study.

Thiffault, Pierre; Bergeron, Jacques

2003-05-01

Studies have shown that drowsiness and hypovigilance frequently occur during highway driving and that they may have serious implications in terms of accident causation. This paper focuses on the task induced factors that are involved in the development of these phenomena. A driving simulator study was conducted in order to evaluate the impact of the monotony of roadside visual stimulation using a steering wheel movement (SWM) analysis procedure. Fifty-six male subjects each drove during two different 40-min periods. In one case, roadside visual stimuli were essentially repetitive and monotonous, while in the other one, the environment contained disparate visual elements aiming to disrupt monotony without changing road geometry. Subject's driving performance was compared across these conditions in order to determine whether disruptions of monotony can have a positive effect and help alleviate driver fatigue. Results reveal an early time-on-task effect on driving performance for both driving periods and more frequent large SWM when driving in the more monotonous road environment, which implies greater fatigue and vigilance decrements. Implications in terms of environmental countermeasures for driver fatigue are discussed.

To perform a comprehensive and systematic review regarding ophthalmic adverse drug reactions (ADRs) to systemic drugs to: (i) systematically summarize existing evidence, (ii) identify areas, ophthalmic ADRs or drugs that lacked systematization or assessment (namely drugs with original studies characterizing specific ophthalmic ADRs but without causality assessment nor without meta-analysis). Systematic review of several electronic databases (last search 1/7/2012): Medline, SCOPUS, ISI web of knowledge, ISI Conference Proceedings, International Pharmaceutical Abstracts and Google scholar. Search query included: eye, ocular, ophthalmic, ophthalmology, adverse and reaction. Inclusion criteria were: (i) Primary purpose was to assess an ophthalmic ADR to a systemic medication; (ii) Patient evaluation performed by an ophthalmologist; (iii) Studies that specified diagnostic criteria for an ocular ADR. Different types of studies were included and analyzed separately. Two independent reviewers assessed eligibility criteria, extracted data and evaluated risk of bias. From 562 studies found, 32 were included (1 systematic review to sildenafil, 11 narrative reviews, 1 trial, 1 prospective study, 6 transversal studies, 6 spontaneous reports and 6 case series). Drugs frequently involved included amiodarone, sildenafil, hydroxychloroquine and biphosphonates. Frequent ophthalmic ADRs included: keratopathy, dry eye and retinopathy. To increase evidence about ophthalmic ADRs, there is a need for performing specific systematic reviews, applying strictly the World Health Organization's (WHO) definition of ADR and WHO causality assessment of ADRs. Some ophthalmic ADRs may be frequent, but require ophthalmological examination; therefore, ophthalmologists' education and protocols of collaboration between other specialties whenever they prescribe high-risk drugs are suggestions for the future.

Nonischemic left ventricular scar (NLVS) is a pattern of myocardial injury characterized by midventricular and/or subepicardial gadolinium hyperenhancement at cardiac magnetic resonance, in absence of significant coronary artery disease. We aimed to evaluate the prevalence of NLVS in juvenile sudden cardiac death and to ascertain its etiology at autopsy. We examined 281 consecutive cases of sudden death of subjects aged 1 to 35 years. NLVS was defined as a thin, gray rim of subepicardial and/or midmyocardial scar in the left ventricular free wall and/or the septum, in absence of significant stenosis of coronary arteries. NLVS was the most frequent finding (25%) in sudden deaths occurring during sports. Myocardial scar was localized most frequently within the left ventricular posterior wall and affected the subepicardial myocardium, often extending to the midventricular layer. On histology, it consisted of fibrous or fibroadipose tissue. Right ventricular involvement was always present. Patchy lymphocytic infiltrates were frequent. Genetic and molecular analyses clarified the etiology of NLVS in a subset of cases. Electrocardiographic (ECG) recordings were available in more than half of subjects. The most frequent abnormality was the presence of low QRS voltages (<0.5 mV) in limb leads. In serial ECG tracings, the decrease in QRS voltages appeared, in some way, progressive. NLVS is the most frequent morphologic substrate of juvenile cardiac sudden death in sports. It can be suspected based on ECG findings. Autopsy study and clinical screening of family members are required to differentiate between arrhythmogenic right ventricular cardiomyopathy/dysplasia and chronic acquired myocarditis.

Neuroendocrine Disorders in Pediatric Craniopharyngioma Patients

PubMed Central

Daubenbüchel, Anna M. M.; Müller, Hermann L.

2015-01-01

Childhood-onset craniopharyngiomas are partly cystic embryonic malformations of the sellar/parasellar region. The therapy of choice in patients with favorable tumor localization is complete resection with a specific focus on maintaining optical and hypothalamic neuroendocrine functions. In patients with unfavorable tumor localization (i.e., hypothalamic involvement), a limited hypothalamus-sparing surgical strategy followed by local irradiation is recommended. Involvement and/or surgical lesions of posterior hypothalamic areas cause major neuroendocrine sequelae. The overall survival rates are high (92%) but neuroendocrine disorders such as obesity and metabolic syndrome due to involvement and/or treatment-related hypothalamic lesions have major negative impact on survival and quality of life. Recurrences and progressions are frequent post-surgical events. Because irradiation is efficient in preventing tumor progression, appropriate timing of post-surgical irradiation is currently under investigation in a randomized multinational trial (KRANIOPHARYNGEOM 2007). Childhood-onset craniopharyngioma should be recognized as a chronic disease requiring treatment and constant monitoring of the clinical and quality of life consequences, frequently impaired due to neuroendocrine disorders, by experienced multidisciplinary teams in order to provide optimal care of surviving patients.

Extensor Tendon Injuries and Repairs in the Hand

PubMed Central

Kontor, J. A.

1982-01-01

Due to their superficial course, the extensor tendons are frequently lacerated over the dorsum of the hand and fingers. Excellent functional results are obtained in repairs of simple tendon lacerations. ‘Open’ mallet lacerations over the distal IP joint or involving the central extensor slip over the proximal IP joint require more precise suturing methods. More proximal extensor tendon divisions near the wrist involve dissection of the retracted finger extensors or long thumb extensor in the distal forearm and more formal tendon repairs, including a possible tendon transfer to the thumb. ‘Closed injuries’, with varying degrees of extensor tendon disruption, occur at three main sites. The mallet injury at the DIP joint and the boutonnière deformity over the PIP joint are sometimes recognized late, but respond to conservative splinting for a minimum of four weeks with guarded motion avoiding secondary stiffening of the remaining small joints of the hand. Surgery of closed injuries most frequently involves the intra-articular traction fracture type of mallet deformities in which the DIP joint has taken the brunt of the injury. PMID:21286174

Study participants (N = 348) were asked about 46 reasons that have been suggested for why people use or do not use condoms. Participants were asked which of these reasons motivated them when they were deciding whether to use condoms in 503 sexual relationships. Participants were classified into one of three roles based on their HIV status and the status of each sexual partner: HIV+ people with HIV- partners; HIV- people with HIV+ partners; and HIV- people with HIV- partners. Motivations were looked at in the context of each of these roles. Of the 46 reasons, only 15 were selected by at least 1/3 of the participants, and only seven were selected by at least half. Frequently reported reasons primarily concern protecting self and partner from STDs including HIV. Less frequently reported reasons involved social norms, effects of condoms on sex, and concern for the relationship. These findings have implications for clinical interventions.

The microbiota of acute apical abscesses.

Siqueira, J F; Rôças, I N

2009-01-01

As the breadth of bacterial diversity in the oral cavity has been deciphered by molecular studies, several newly identified species/phylotypes have emerged as potential pathogens. We hypothesized that many of these species/phylotypes could also be involved with the etiology of endodontic abscesses. Abscess aspirates from 42 persons were analyzed for the presence of 81 species/phylotypes by means of a reverse-capture checkerboard hybridization assay. Associations between the most frequently detected taxa were calculated. The most prevalent taxa were Fusobacterium nucleatum, Parvimonas micra, and Porphyromonas endodontalis. Other frequently found taxa included Olsenella uli, streptococci, Eikenella corrodens, some as-yet-uncultivated phylotypes (Bacteroidetes clone X083 and Synergistes clone BA121), and newly named species (Prevotella baroniae and Dialister invisus). Several positive bacterial associations were disclosed. Findings not only strengthen the association of many cultivable species with abscesses, but also include some newly named species and uncultivated phylotypes in the set of candidate pathogens associated with this disease.

The Moses, mega-Moses, and Armstrong illusions: integrating language comprehension and semantic memory.

PubMed

Shafto, M; MacKay, D G

2000-09-01

This study develops a new theory of the Moses illusion, observed in responses to general knowledge questions such as, "How many animals of each kind did Moses take on the Ark?" People often respond "two" rather than "zero" despite knowing that Noah, not Moses, launched the Ark. Our theory predicted two additional types of conceptual error demonstrated here: the Armstrong and mega-Moses illusions. The Armstrong illusion involved questions resembling, "What was the famous line uttered by Louis Armstrong when he first set foot on the moon?" People usually comprehend such questions as valid, despite knowing that Louis Armstrong was a jazz musician who never visited the moon. This Armstrong illusion was not due to misperceiving the critical words (Louis Armstrong), and occurred as frequently as the Moses illusion (with critical words embedded in identical sentential contexts), but less frequently than the mega-Moses illusion caused when Moses and Armstrong factors were combined.

Childhood burns in south eastern Nigeria.

Archibong, A E; Antia, U E; Udosen, J

1997-06-01

In a ten year retrospective study of burns in children in University of Calabar Teaching Hospital (UCTH), Calabar, the main causes were hot water, hot soup or oil (56.6%) involving children mostly in the one to three year age group. The relative safety of the home environment seen in other forms of paediatric trauma is not observed in burns in children. A changing pattern of burns in children has emerged within the region with naked flames/bush fire coming second and affecting 22.7% of the children. Chemical burns hitherto a rare occurrence is now frequent because of the storage of caustic soda and acids in living rooms by soap making parents. Burns affecting the perineum, axilla and buttocks are difficult to keep clean and frequently lead to infections, with associated increased morbidity. Causes of childhood burns are largely preventable requiring active social/medical education and public enlightenment campaigns on the various methods of prevention.

The company objects keep: Linking referents together during cross-situational word learning.

2018-04-01

Learning the meanings of words involves not only linking individual words to referents but also building a network of connections among entities in the world, concepts, and words. Previous studies reveal that infants and adults track the statistical co-occurrence of labels and objects across multiple ambiguous training instances to learn words. However, it is less clear whether, given distributional or attentional cues, learners also encode associations amongst the novel objects. We investigated the consequences of two types of cues that highlighted object-object links in a cross-situational word learning task: distributional structure - how frequently the referents of novel words occurred together - and visual context - whether the referents were seen on matching backgrounds. Across three experiments, we found that in addition to learning novel words, adults formed connections between frequently co-occurring objects. These findings indicate that learners exploit statistical regularities to form multiple types of associations during word learning.

School sports accidents: analysis of causes, modes, and frequencies.

2001-01-01

About 5% of all school children are seriously injured during physical education every year. Because of its influence on children's attitude toward sports and the economic aspects, an evaluation of causes and medical consequences is necessary. In this study, 213 school sports accidents were investigated. Besides diagnosis, the localization of injuries, as well as the duration of the sick leave were documented. Average age of injured students was 13 years. Most of the injured students blamed themselves for the accident. The most common injuries were sprains, contusions, and fractures. Main reasons for the accidents were faults in basic motion training. Playing soccer and basketball were the most frequent reasons for injuries. The upper extremity was more frequently involved than the lower extremity. Sports physicians and teachers should work out a program outlining the individual needs and capabilities of the injured students to reintegrate them into physical education.

To describe the clinical features of Ocular Toxoplasmosis in pediatric patients. A retrospective, non-comparative series of cases was studied. We reviewed the clinical records of patients 16 year old or younger diagnosed with Ocular Toxoplasmosis. Forty patients (56 eyes) were included. The mean age was 9.5 yrs old. Twenty were female. Unilateral involvement was noticed in 60% of patients. The most common symptoms were strabismus (32.1%) and reduced VA in (23.2%). An inactive retinal scar was observed in most cases (71.4%). Panuveitis was found in 8 eyes (14.2%), and posterior uveitis in 7 eyes of 7 patients (12.5%); one eye presented neuroretinitis. The most frequent location of retinochoroidal lesions was the posterior pole (72.7%). In children, ocular toxoplasmosis is most commonly diagnosed during the inactive stage. When inflammation is present, it can be severe and frequently associated with other complications such vasculitis and papillitis.

Victims of electrical burns account for approximately 5% of admissions to major burn centers. The first case of visceral injury caused by electrical burns was described in 1927 by Simonin, who reported perforation of the small intestine. Other rare cases were reported over the following years. The colon and small intestine were the organs most frequently affected. Less frequently involved organs were the heart, esophagus, stomach, pancreas, liver, gallbladder, lung, and kidney. We highlight the potential fatal visceral injuries after the electrical trauma. This study provides a review on this topic and proposes a management flowchart that should be adopted by the multidisciplinary team to treat these patients. Conclusion: Visceral injuries are rare in electrical burns victims, but it can be severe and are associated with high rates of morbidity and mortality, sometimes requiring a more interventional approach.

The Marijuana Motives Measure (MMM) has so far been examined mainly in student populations, often with relatively limited involvement in cannabis use. This study evaluated the factor structure of the MMM in a demographically mixed sample of 600 young adult (18-30 years) frequent (≥ 3 days per week) cannabis users in the Netherlands. Analysis confirmed a five-factor solution, denoting coping, enhancement, social, conformity and expansion motives. Additionally, the original MMM was extended with two items (boredom and habit), which formed a distinct, internally consistent sixth factor labelled routine motives. In a multivariable logistic regression analysis, coping and routine motives showed significant associations with 12-month DSM-IV cannabis dependence. The results suggest general reliability and validity of the MMM in a heterogeneous population of experienced cannabis users. Copyright © 2014 Elsevier Ltd. All rights reserved.

West Nile Virus Retinopathy and Associations with Long Term Neurological and Neurocognitive Sequelae.

West Nile virus (WNV) has emerged as an important vector-borne pathogen in North America, with more than 3 million estimated to have been infected. Retinopathy from WNV infection has been previously reported in acute cases, though those prior reports did not evaluate the risk of retinopathy based on clinical severity of neurologic disease. The purpose of this cross-sectional study was to perform comprehensive ophthalmological and neurological examinations on 111 patients with a history of West Nile virus infection and describe the ocular manifestations. Out of 111 patients, 27 (24%) had evidence for West Nile virus associated retinopathy (WNVR); this observation was higher (49%) in those patients who initially presented with encephalitis. Individuals with WNVR had more frequent involvement of the macula and peripheral involvement compared to those patients without WNVR (p<0.05). WNVR was also associated with a greater likelihood of abnormal reflexes on neurological exam, poorer learning, greater dependence in activities of daily living, and lower quality of life (p<0.05). WNVR was seen more frequently in elderly patients (age > 60 years), and was associated with higher rates of diabetes mellitus and a history of encephalitis (p<0.05). A multivariable logistic regression revealed that only a history of encephalitis was independently associated with WNVR [Adjusted Odds Ratio = 4.9 (1.8-13.2); p = 0.001]. Our study found that WNVR occurs in one fourth of patients with a history of WNV infection and is more frequently observed in those with apparent severe neurological sequelae (e.g., encephalitis). The clinical relevance of WNVR was supported by its associations with dependence in activities of daily living and lower quality of life. This unique evaluation of WNV patients included fundoscopic examinations and their associations with neurologic impairment. Our findings can be used during ophthalmological consultation for the evaluation, treatment and rehabilitation phases of care for WNV patients.

Periapical lesions are common sequelae of pulp diseases. This retrospective study evaluated the clinical and histopathological features of periapical lesions sent to a private pathology laboratory by dentists in private clinics. Two hundred and fifty-two consecutive cases of periapical lesions were collected from September 2005 to October 2009. Clinical data and histopathological features of these periapical lesions were reviewed and analyzed. The 252 periapical lesions consisted of 128 periapical granulomas, 117 periapical cysts, and seven periapical scars. These 252 lesions were taken from 252 patients (92 men and 160 women; mean age = 43.6 years; range, 9-81 years). Of the 252 periapical lesions, 186 were found in the maxilla and 66 in the mandible. The most common site for periapical lesions was the maxillary anterior region (134 cases, including 73 granulomas, 54 cysts and 7 scars), and the most frequently involved tooth was the maxillary lateral incisor (64 cases, including 29 granulomas, 31 cysts and 4 scars). Of the 117 periapical cysts, 116 were lined by stratified squamous epithelium and one by mucoepidermoid epithelium. Hyaline bodies were discovered in the lining epithelium of four periapical cysts. Odontogenic epithelial rest, cholesterol cleft, foamy histiocytes, hemosiderin-laden macrophages, dystrophic calcification, foreign bodies, and bacterial clumps were found in five, three, nine, two, 28, 10 and one periapical granulomas, respectively, as well as in six, 11, eight, seven, 19, nine and eight periapical cysts, respectively. Granulomas and cysts were the two most common periapical lesions. Periapical lesions occurred more frequently in female patients and in those in their fourth to fifth decades. The most commonly affected site for periapical lesions was the maxillary anterior region, and the most frequently involved tooth was the maxillary lateral incisor.

2005-01-01

There are increasing numbers of legal suits concerning access to medicines brought against the Rio de Janeiro State Health Department. The situation indicated the need for a study to clarify the underlying issues. A sample of 389 court suits from January 1991 to December 2001 (stratified by year) was used. A cross-sectional design was used to describe and analyze the legal suits in relation to the responsibilities defined under the Unified National Health System (SUS). Results suggest major delays in court decisions. Most suits are filed by the Public Defender's Office for users of the National Health System. The most frequent cases involve medicines for the cardiovascular and nervous systems, many of which involve continuous use. Prescribing practices are institutionalized through the inclusion of the most frequently prescribed drugs in public financing lists, which makes rational drug use difficult to achieve. Municipalities are not fulfilling their responsibility to supply medicines to users, and the State is thus encumbered with these responsibilities. However, the State does not adequately supply medicines to the municipalities. The apparent lack of awareness among both lawyers and clients generates stress between the Executive and Judiciary branches and limits the resources for collective pharmaceutical services.

To determine clinical and epidemiological features of scorpion stings in two departments of Colombia, a descriptive study was performed in the hospitals of 10 towns from Antioquia (2 256 071 inhabitants) and five from Tolima (630 424 inhabitants). One hundred and twenty-nine cases were admitted during one year, 51 in Antioquia, 78 in Tolima and 41 were children less than 15 years old. Most stings (70.5%) occurred inside the house; 27.9% were on the hands and 26.4% on the feet. The scorpion species involved were Tityus pachyurus (51), Centruroides gracilis (31), T. fuehrmanni (29), T. asthenes (7) and Chactas spp. (1). In 10 cases the scorpion involved was not identified. Systemic envenoming signs (e.g. vomiting, tachypnea) were significantly more frequent in children than in adults (P < 0.05). Four children had hypertension, but none developed pulmonary oedema. One 3-year-old girl, stung by T. asthenes, had acute oedematous pancreatitis. Ninety-eight patients had mild envenoming. Moderate (27 patients) and severe (four patients) envenoming was significantly more frequent in children than in adults (P = 0.003; relative risk = 2.97). A pepsin-digested anti-Centruroides spp. antivenom was administered to 19 of 31 patients presenting systemic envenoming signs. No adverse reactions to antivenom were observed.

The parieto-occipital region of the brain is the most frequently and severely affected in subacute sclerosing panencephalitis (SSPE). The basal ganglia, cerebellum and corpus callosum are less commonly involved. We describe a patient with SSPE confirmed by neuropathology based on brain magnetic resonance imaging showing extensive basal ganglia involvement and no significant involvement of other cortical structures. Though rarely described in SSPE, clinicians should be aware of this involvement. SSPE should be kept in mind when changes in basal ganglia signal are seen on brain magnetic resonance imaging with or without involvement of other regions of the human brain to avoid erroneous etiological diagnosis of other pathologies causing rapidly progressive dementia.

2015-02-01

Although there are several evidence-based recommendations directed at improving nutrition and physical activity standards in schools, these guidelines have not been uniformly adopted throughout the United States. Consequently, research is needed to identify facilitators promoting schools to implement these recommendations. Therefore, this study analyzed the 2008 School Health Profiles Principal Survey (Profiles) to explore the role of family and community involvement in school nutrition and physical activity standards. Survey data on nutrition and physical activity policies, as well as family and community involvement, were available for 28 states, representing 6732 secondary schools. One-factor analysis of variance (ANOVA), 2-sample t-tests, Pearson's chi-square tests, and multiple logistic and linear regression models were employed in this analysis. Family and community involvement were associated with schools more frequently utilizing healthy eating strategies and offering students healthier food options. Further, involvement was associated with greater support for physical education staff and more intramural sports opportunities for students. Though family and community involvement have the potential to have a positive influence on school nutrition and physical activity policies and practices, involvement remains low in schools. Increased efforts are needed to encourage collaboration among schools, families, and communities to ensure the highest health standards for all students. © 2015, American School Health Association.

Causes of death were examined for 1,103 systemic lupus erythematosus patients who were followed from 1965 to 1978 at 9 centers that participated in the Lupus Survival Study Group. A total of 222 patients (20%) died. Lupus-related organ system involvement (mainly active nephritis) and infection were the most frequent primary causes of death. Causes of death were similar throughout the followup period. Hemodialysis had little impact on the length of survival for patients with nephritis. Active central nervous system disease and myocardial infarction were infrequent causes of death. There were no deaths from malignancy.

Immunoglobulin levels of individual classes and IgG subclasses and the occurrence of homogeneous immunoglobulins--paraproteins--were studied longitudinally in the sera of three patients with the Wiskott-Aldrich syndrome; Common findings in all three patients were great variations in the immunoglobulin levels, restricted heterogeneity of the immunoglobulins, the frequent appearance of transient homogeneous immunoglobulins and the presence of serum antibodies against bovine milk proteins. A partial and selective deficiency involving mainly the T immune system is postulated as an explanation for these findings. Images Fig. 2 Fig. 3 Fig. 4 PMID:954233

Many of the patients admitted to a general medical ward have a compromised quality of life, or short life expectancy, so they are potential candidates for withhold/withdraw (WH/WD) treatment. The first objectif was to describe which measures were WH/WD among patients who died during their admission in a general medical ward from a tertiary hospital in Madrid. Secondly, to define the clinical characteristics of this population. A cross-sectional descriptive study during 6 months from 2011 and 2012 of all the patients dead while their admission in the Internal Medicine Department. 2007 patients were admitted, 211 died (10.5%). 121 (57%) were female, with 85±9 years of mean age. 103 (48.8%) came from a residential facility and 105 fulfilled terminality criteria (49.8%). One decision to WH/WD treatment was made in 182 patients (86.3%, CI 95%: 81.4-91.1), two in 99 cases (46.9%, CI 95%: 39.9-53.9) and 3 or more in 31 subjects (14.7%, CI 95%: 9.6-19.7). The most frequent decisions involved do-not-resuscitate orders (154, 73.0%), rejection of «aggressive treatment measures» (80, 38.0%), use of antibiotics (19, 9.0%), admission in ICU (18, 8.5%), and/or surgical treatment (11, 5.2%). WH/WD treatment is very frequent among patients who died in a general medical ward. The most frequent involved do-not-resuscitate orders and rejection of «aggressive treatment measures».

[Desmoplastic Spitz nevus: a histopathological review and comparison with desmoplastic melanoma].

PubMed

Nojavan, H; Cribier, B; Mehregan, D R

2009-10-01

Desmoplastic Spitz nevus is a rare variant of spitzoid tumours characterized by dermal proliferation of large epitheliod and/or fusiform melanocytes within a desmoplastic stroma, comprising thick, eosinophilic collagen bundles. It occurs most frequently in young adults and children, and exhibits a predilection for the limbs. Histologically, this entity may be mistaken for cutaneous fibrous tumours or desmoplastic melanoma. To establish useful histological criteria for differential diagnosis of desmoplastic Spitz nevus, we conducted a retrospective study comparing data concerning the clinical, demographic and histological characteristics of desmoplastic Spitz nevus and desmoplastic melanoma. We reviewed the slides for 28 cases of desmoplastic Spitz nevus and for 13 cases of desmoplastic melanoma obtained from the files of Pinkus Dermatopathology Laboratory (Monroe, MI, USA) during the period 1993-2005. Desmoplastic Spitz nevus was more common in women (sex ratio M/F=0.4) and younger patients (mean age: 28.2 years) whereas the mean age of patients with desmoplastic melanoma was significantly higher (mean age: 75 years). From a histopathological point of view, symmetry, circumscription, melanocytic maturation and involvement of adnexal structure were significantly more frequent in desmoplastic Spitz nevi. The presence of melanocytic junctional nests associated with discohesive cells, variations in size and shape of the nests, lentiginous melanocytic proliferation, actinic elastosis, pagetoid spread, dermal mitosis, perineural involvement and brisk inflammatory infiltrate were significantly more frequent in desmoplastic melanoma. No significant difference was found concerning epidermal hyperplasia, presence of Kamino bodies or moderate inflammatory infiltrate. The combination of architectural and cytological features was useful in differentiating desmoplastic Spitz nevus from desmoplastic melanoma. A complete excision biopsy is mandatory in such tumors as the architectural criteria are necessary for a correct diagnosis.

MITF/TFE translocation renal cell carcinoma (TRCC) is a rare subtype of kidney cancer. Its incidence and the genome-wide characterization of its genetic origin have not been fully elucidated. We performed RNA and exome sequencing on an exploratory set of TRCC (n = 7), and validated our findings using The Cancer Genome Atlas (TCGA) clear-cell RCC (ccRCC) dataset (n = 460). Using the TCGA dataset, we identified seven TRCC (1.5%) cases and determined their genomic profile. We discovered three novel partners of MITF/TFE (LUC7L3, KHSRP, and KHDRBS2) that are involved in RNA splicing. TRCC displayed a unique gene expression signature as compared with other RCC types, and showed activation of MITF, the transforming growth factor β1 and the PI3K complex targets. Genes differentially spliced between TRCC and other RCC types were enriched for MITF and ID2 targets. Exome sequencing of TRCC revealed a distinct mutational spectrum as compared with ccRCC, with frequent mutations in chromatin-remodeling genes (six of eight cases, three of which were from the TCGA). In two cases, we identified mutations in INO80D, an ATP-dependent chromatin-remodeling gene, previously shown to control the amplitude of the S phase. Knockdown of INO80D decreased cell proliferation in a novel cell line bearing LUC7L3-TFE3 translocation. This genome-wide study defines the incidence of TRCC within a ccRCC-directed project and expands the genomic spectrum of TRCC by identifying novel MITF/TFE partners involved in RNA splicing and frequent mutations in chromatin-remodeling genes. ©2014 American Association for Cancer Research.

Corporal punishment is still widely practiced around the globe, despite the large body of child development research that substantiates its short- and long-term consequences. Within this context, this paper examined the relationship between parental use of corporal punishment and youth externalizing behavior with a Chilean sample to add to the growing empirical evidence concerning the potential relationship between increased corporal punishment and undesirable youth outcomes across cultures. Analysis was based on 919 adolescents in Santiago, Chile. Descriptive and multivariate analyses were conducted to examine the extent to which parents' use of corporal punishment and positive family measures were associated with youth externalizing behavior. Furthermore, the associations between self-reported externalizing behavior and infrequent, as well as frequent, use of corporal punishment were investigated to understand how varying levels of parental use of corporal punishment were differently related to youth outcomes. Both mothers' and fathers' use of corporal punishment were associated with greater youth externalizing behavior. Additionally, increases in positive parenting practices, such as parental warmth and family involvement, were met with decreases in youth externalizing behavior when controlling for youth demographics, family socioeconomic status, and parents' use of corporal punishment. Finally, both infrequent and frequent use of corporal punishment were positively associated with higher youth problem behaviors, though frequent corporal punishment had a stronger relationship with externalizing behavior than did infrequent corporal punishment. Parental use of corporal punishment, even on an occasional basis, is associated with greater externalizing behavior for youth while a warm and involving family environment may protect youth from serious problem behaviors. Therefore, findings of this study add to the growing evidence concerning the negative consequences of corporal punishment for youth outcomes. Copyright © 2012 Elsevier Ltd. All rights reserved.

Anti-endothelial cell antibodies (AECA) have been described in systemic sclerosis (SSc) but their clinical relevance is unclear. Aim of this study was to measure serum levels of AECA in 62 SSc patients, examining the main clinical and laboratory features, including nailfold capillaroscopy (NC) abnormalities and looking for any significant association. Fourteen patients (23%) were AECA positive. An "early" NC pattern was observed in 21 patients (34%), an "active" pattern in 24 (39%) and a "late" pattern in 17 cases (27%). In those patients with AECA, a "late" NC pattern was significantly more frequent respect to the "early" and "late" patterns (p<0.05); besides AECA serum levels were significantly higher in the "late" group of patients respect to the other two (p<0.04 and p<0.02 respectively), also showing a significantly more severe modified skin score (mSS) (> or =15) (p<0.04), while those cases with more aggressive NC patterns ("active" and "late") had a more frequent finding of arterial hypertension (p<0.05) and cardiac involvement (p<0.05) respect to those with "early" NC pattern. Thus, advanced NC findings were more frequently found in those patients with higher levels of AECA and their contemporary presence may consent to identify specific SSc subsets i.e., those with higher skin scores and cardiovascular involvement. These data suggest that AECA may have a role in the progression of the endothelial damage and their presence and titer should be considered as an adjunctive risk factor for a more severe disease. We also confirm the diagnostic and prognostic validity for NC in SSc, underlying the importance for an accurate capillaroscopic assessment. The contemporary assessment of these two diagnostic tools can be useful to better define different subset of SSc patients.

Global/local processing of hierarchical visual stimuli in a conflict-choice task by capuchin monkeys (Sapajus spp.).

In the last two decades, comparative research has addressed the issue of how the global and local levels of structure of visual stimuli are processed by different species, using Navon-type hierarchical figures, i.e. smaller local elements that form larger global configurations. Determining whether or not the variety of procedures adopted to test different species with hierarchical figures are equivalent is of crucial importance to ensure comparability of results. Among non-human species, global/local processing has been extensively studied in tufted capuchin monkeys using matching-to-sample tasks with hierarchical patterns. Local dominance has emerged consistently in these New World primates. In the present study, we assessed capuchins' processing of hierarchical stimuli with a method frequently adopted in studies of global/local processing in non-primate species: the conflict-choice task. Different from the matching-to-sample procedure, this task involved processing local and global information retained in long-term memory. Capuchins were trained to discriminate between consistent hierarchical stimuli (similar global and local shape) and then tested with inconsistent hierarchical stimuli (different global and local shapes). We found that capuchins preferred the hierarchical stimuli featuring the correct local elements rather than those with the correct global configuration. This finding confirms that capuchins' local dominance, typically observed using matching-to-sample procedures, is also expressed as a local preference in the conflict-choice task. Our study adds to the growing body of comparative studies on visual grouping functions by demonstrating that the methods most frequently used in the literature on global/local processing produce analogous results irrespective of extent of the involvement of memory processes.

Objective To identify existing evidence on interagency collaboration between law enforcement, emergency services, statutory services and third sector agencies regarding people with mental ill health. Design Systematic scoping review. Scoping reviews map particular research areas to identify research gaps. Data sources and eligibility ASSIA, CENTRAL, the Cochrane Library databases, Criminal Justice Abstracts, ERIC, Embase, MEDLINE, PsycINFO, PROSPERO and Social Care Online and Social Sciences Citation Index were searched up to 2017, as were grey literature and hand searches. Eligible articles were empirical evaluations or descriptions of models of interagency collaboration between the police and other agencies. Study appraisal and synthesis Screening and data extraction were undertaken independently by two researchers. Arksey’s framework was used to collate and map included studies. Results One hundred and twenty-five studies were included. The majority of articles were of descriptions of models (28%), mixed methods evaluations of models (18%) and single service evaluations (14%). The most frequently reported outcomes (52%) were ‘organisational or service level outcomes’ (eg, arrest rates). Most articles (53%) focused on adults with mental ill health, whereas others focused on adult offenders with mental ill health (17.4%). Thirteen models of interagency collaboration were described, each involving between 2 and 13 agencies. Frequently reported models were ‘prearrest diversion’ of people with mental ill health (34%), ‘coresponse’ involving joint response by police officers paired with mental health professionals (28.6%) and ‘jail diversion’ following arrest (23.8%). Conclusions We identified 13 different interagency collaboration models catering for a range of mental health-related interactions. All but one of these models involved the police and mental health services or professionals. Several models have sufficient literature to warrant full systematic reviews of their effectiveness, whereas others need robust evaluation, by randomised controlled trial where appropriate. Future evaluations should focus on health-related outcomes and the impact on key stakeholders. PMID:29588323

The role of fathers in shaping their child's eating behaviour and weight status through their involvement in child feeding has rarely been studied. This study aims to describe fathers' perceived responsibility for child feeding, and to identify predictors of how frequently fathers eat meals with their child. Four hundred and thirty-six Australian fathers (M age = 37 years, SD = 6 years; 34% university educated) of a 2-5-year-old child (M age = 3.5 years, SD = 0.9 years; 53% boys) were recruited via contact with mothers enrolled in existing research projects or a university staff and student email list. Data were collected from fathers via a self-report questionnaire. Descriptive and hierarchical linear regression analyses were conducted. The majority of fathers reported that the family often/mostly ate meals together (79%). Many fathers perceived that they were responsible at least half of the time for feeding their child in terms of organizing meals (42%); amount offered (50%) and deciding if their child eats the 'right kind of foods' (60%). Time spent in paid employment was inversely associated with how frequently fathers ate meals with their child (β = -0.23, P < 0.001); however, both higher perceived responsibility for child feeding (β = 0.16, P < 0.004) and a more involved and positive attitude toward their role as a father (β = 0.20, P < 0.001) were positively related to how often they ate meals with their child, adjusting for a range of paternal and child covariates, including time spent in paid employment. Fathers from a broad range of educational backgrounds appear willing to participate in research studies on child feeding. Most fathers were engaged and involved in family meals and child feeding. This suggests that fathers, like mothers, should be viewed as potential agents for the implementation of positive feeding practices within the family. © 2013 John Wiley & Sons Ltd.

Fungal infections of the mucous membrane.

Marques, Silvio Alencar

2010-01-01

A clinical review of three potentially severe fungal diseases, which are characterized in many cases by mucosal involvement, is presented. They are paracoccidioidomycosis, histoplasmosis, and mucormycosis. Mucosal involvement for paracoccidioidomycosis and rhinocerebral mucormycosis is frequent. Thus, oral involvement may provide early clue for diagnosis. In paracoccidioidomycosis, the mucosal lesion classically shows superficial ulcers with granular appearance and hemorrhagic points, usually on lips, palate, and jugal mucosa. In mucormycosis, necrosis of the palate followed for purulent discharge is a hallmark of rhinocerebral disease. Treatment with amphotericin B desoxycholate or the new second-generation triazoles is highly efficacious.

Neurological manifestations of systemic lupus erythematosus are frequent and polymorphic. Their frequency varies according to authors (24-75p.cent). Central nervous system complications predominate; peripheral features are rare, classically symmetrical polyneuropathy, multiple mononeuropathies or cranial nerve involvement. We report a case of a 48-year-old woman presenting a histologically documented sensitivo-motor polyneuropathy with severe motor involvement complicating lupus associated with antiphospholipides antibodies. Outcome was good after cyclophosphamid pulse. We discuss the frequency of peripheral involvement in systemic lupus erythematosus, pathogenic mechanisms, therapeutic possibilities and outcome of this complication.

The orbital bones may show nearly all the pathologic changes observed in the skull and in the face. The congenital anomalies in this area are numerous and involve various forms of craniostenoses. Among the benign osseous tumors the osteoma is most frequently encountered in the orbit. Fibrous dysplasia is a tumefaction of indeterminate behavior that often involves the orbit. Osteosarcoma or other malignant neoplasms are rarely seen in this area. Eosinophilic granuloma and Hand-Schüller-Christian disease are tumor-like lesions that may involve the orbit.

This study examined differences in religious participation and spirituality among African Americans, Caribbean Blacks (Black Caribbeans) and non-Hispanic Whites. Data are taken from the National Survey of American Life, a nationally representative study of African Americans, Black Caribbeans and non-Hispanic Whites. Selected measures of organizational, nonorganizational and subjective religious participation were examined. African American and Caribbean Blacks were largely similar in their reports of religious involvement; both groups generally indicated higher levels of religious participation than non-Hispanic Whites. African Americans were more likely than Black Caribbeans to be official members of their places of worship, engage in activities (choirs, church clubs) at their place of worship and request prayer from others. Black Caribbeans reported reading religious materials more frequently than African Americans. The discussion notes the importance of examining ethnic differences within the black American population of the United States. PMID:20975850

The Synthesis of Proteins-A Simple Experiment To Show the Procedures and Problems of Using Radioisotopes in Biochemical Studies

NASA Astrophysics Data System (ADS)

Hawcroft, David M.

1996-11-01

Courses of organic chemistry frequently include studies of biochemistry and hence of biochemical techniques. Radioisotopes have played a major role in the understanding of metabolic pathways, transport, enzyme activity and other processes. The experiment described in this paper uses simple techniques to illustrate the procedures involved in working with radioisotopes when following a simplified metabolic pathway. Safety considerations are discussed and a list of safety rules is provided, but the experiment itself uses very low levels of a weak beta-emitting isotope (tritium). Plant material is suggested to reduce legal, financial and emotive problems, but the techniques are applicable to all soft-tissued material. The problems involved in data interpretation in radioisotope experiments resulting from radiation quenching are resolved by simple correction calculations, and the merits of using radioisotopes shown by a calculation of the low mass of material being measured. Suggestions for further experiments are given.

Research on the cognitive benefits of working memory training programs has produced inconsistent results. Such research has frequently used laboratory-specific training tasks, or dual-task n-back training. The current study used the commercial Cogmed Working Memory (WM) Training program, involving several different training tasks involving visual and auditory input. Healthy college undergraduates were assigned to either the full Cogmed training program of 25, 40-min training sessions; an abbreviated Cogmed program of 25, 20-min training sessions; or a no-contact control group. Pretest and posttest measures included multiple measures of attention, working memory, fluid intelligence, and executive functions. Although improvement was observed for the full training group for a digit span task, no training-related improvement was observed for any of the other measures. Results of the study suggest that WM training does not improve performance on unrelated tasks or enhance other cognitive abilities.

Alagille syndrome (AS) is a cholestatic disease secondary to scarcity of interlobular bile ducts. It is associated with extrahepatic manifestations, and renal involvement is frequent. To describe the prevalence, type and outcome of renal pathology in children with AS. The presence and outcome of renal pathology was retrospectively studied in 21 children who met AS criteria. Renal pathology was observed in 18 patients (85.7%): (1) ultrasound variations in 7 patients (6 cases of bilateral renal dysplasia and 1 case of renal agenesis); (2) distal renal tubular acidosis in 2 patients; (3) a drop in glomerular filtration and/or proteinuria in 16 patients. The frequency of a drop in glomerular filtration was similar between patients with and without pathological kidney ultrasound findings. Our study confirms a high prevalence of renal involvement, which enhances the importance of diagnosis and renal function follow-up in children with AS. Sociedad Argentina de Pediatría.

Emerging technologies for studying DNA methylation for the molecular diagnosis of cancer

PubMed Central

Marzese, Diego M.; Hoon, Dave S.B.

2015-01-01

DNA methylation is an epigenetic mechanism that plays a key role in regulating gene expression and other functions. Although this modification is seen in different sequence contexts, the most frequently detected DNA methylation in mammals involves cytosine-guanine dinucleotides. Pathological alterations in DNA methylation patterns are described in a variety of human diseases, including cancer. Unlike genetic changes, DNA methylation is heavily influenced by subtle modifications in the cellular microenvironment. In all cancers, aberrant DNA methylation is involved in the alteration of a large number of oncological pathways with relevant theranostic utility. Several technologies for DNA methylation mapping were recently developed and successfully applied in cancer studies. The scope of these technologies varies from assessing a single cytosine-guanine locus to genome-wide distribution of DNA methylation. Here, we review the strengths and weaknesses of these approaches in the context of clinical utility for the molecular diagnosis of human cancers. PMID:25797072

Evidence for the long-term efficacy and safety of anti-tumor necrosis factor α agents (anti-TNF) in treating cutaneous sarcoidosis is lacking. To determine the efficacy and safety of anti-TNF in treating cutaneous sarcoidosis in a large observational study. STAT (Sarcoidosis Treated with Anti-TNF) is a French retrospective and prospective multicenter observational database that receives data from teaching hospitals and referral centers, as well as several pneumology, dermatology, and internal medicine departments. Included patients had histologically proven sarcoidosis and received anti-TNF between January 2004 and January 2016. We extracted data for patients with skin involvement at anti-TNF initiation. Response to treatment was evaluated for skin and visceral involvement using the ePOST (extra-pulmonary Physician Organ Severity Tool) severity score (from 0 [not affected] to 6 [very severe involvement]). Epidemiological and cutaneous features at baseline, efficacy, steroid-sparing, safety, and relapses were recorded. The overall cutaneous response rate (OCRR) was defined as complete (final cutaneous ePOST score of 0 or 1) or partial response (ePOST drop ≥2 points from baseline but >1 at last follow-up). Among 140 patients in the STAT database, 46 had skin involvement. The most frequent lesions were lupus pernio (n = 21 [46%]) and nodules (n = 20 [43%]). The median cutaneous severity score was 5 and/or 6 at baseline. Twenty-one patients were treated for skin involvement and 25 patients for visceral involvement. Reasons for initiating anti-TNF were failure or adverse effects of previous therapy in 42 patients (93%). Most patients received infliximab (n = 40 [87%]), with systemic steroids in 28 cases (61%) and immunosuppressants in 32 cases (69.5%). The median (range) follow-up was 45 (3-103) months. Of the 46 patients with sarcoidosis and skin involvement who were treated with anti-TNF were included, median (range) age was 50 (14-78) years, and 33 patients (72%) were women. The OCRR was 24% after 3 months, 46% after 6 months, and 79% after 12 months. Steroid sparing was significant. Treatment was discontinued because of adverse events in 11 patients (24%), and 21 infectious events occurred in 14 patients (30%). Infections were more frequent in patients treated for visceral involvement than in those treated for skin involvement (n = 12 of 25 [48%] vs n = 2 of 21 [9.5%], respectively; P = .02). The relapse rate was 44% 18 months after discontinuation of treatment. Relapses during treatment occurred in 35% of cases, mostly during anti-TNF or concomitant treatment tapering. Anti-TNF agents are effective but suspensive in cutaneous sarcoidosis. The risk of infectious events must be considered.

The vasculitis of Behçet disease (BD) is distinctive because of involvement of both arteries and veins of all sizes. The concept of vasculo-Behçet disease has been adopted for cases in which vascular manifestations are present and often dominate the clinical features. While venous manifestations are frequent and have been reported in many publications, data regarding arterial lesions in patients with BD are rare and often isolated. In this study, we report the main characteristics, treatment, and long-term outcome of 101 patients with arterial lesions among a cohort of 820 (12.3%) BD patients. Factors that affect prognosis were assessed by multivariate analysis. There were 93 (91.2%) male patients; the median (Q1-Q3) age at diagnosis of BD was 33 (27-41) years. Arterial lesions included aneurysms (47.3%), occlusions (36.5%), stenosis (13.5%), and aortitis (2.7%). Lesions mainly involved the aorta (n = 25) and femoral (n = 23) and pulmonary (n = 21) arteries. Patients with arterial lesions were more frequently male (91.2% vs. 62.4%, respectively; p = 0.017) and had higher rates of venous involvement (80.4% vs. 29.8%, respectively; p < 0.001) compared to patients without arterial manifestations. Thirty-nine (38.6%) patients achieved complete remission. In multivariate analysis, the presence of venous involvement (odds ratio [OR], 0.29; 95% confidence interval [CI], 0.08-1.11) and arterial occlusive lesions (OR, 0.13; 95% CI, 0.01-1.25) were negatively associated with complete remission. The use of immunosuppressants (OR, 3.38; 95% CI, 0.87-13.23) was associated with the occurrence of complete remission. The 20-year survival rate was significantly lower in BD patients with arterial involvement than in those without arterial lesions (73% vs. 89%, respectively; p < 0.0001). In conclusion, the long-term outcome of arterial lesions in BD is poor, especially in the case of occlusive lesions and associated venous involvement. The use of immunosuppressants improved the prognosis.

Behçet’s Syndrome and Thrombosis

PubMed Central

Seyahi, Emire; Yurdakul, Sebahattin

2011-01-01

Behçet syndrome (BS) is a multisystem vasculitis with unknown etiology and a unique geographic distribution. The disease course is characterized by exacerbations and remissions while abating as the years pass. The usual onset is in the third decade. Recurrent skin mucosa lesions and sight threatening panuveitis are the hallmark of the disease. Males are more severely affected than females. Vascular involvement can occur in up to 40% of cases. BS is unique among the vasculitides in that it may involve all sizes and types of vessels. It affects the veins more than the arteries. Lower extremity vein thrombosis is the most frequent manifestation of vascular involvement, followed by vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms. Vascular involvement is frequently associated with constitut onal symptoms and increased acute phase response and is the major cause of increased mortality. A predominantly neutrophilic vasculitis around the vaso vasorum is typical of BS. The thrombus is tightly adherent to the vessel wall which probably explains why thromboembolism is so rare despite the high frequency of venous disease. Thrombophilic factors do not seem to explain thrombotic tendency in BS. Immunosuppressive treatment is essential in suppression and preventing the attacks. PMID:21869912

An extraordinary form of Peyronies disease is reported. The patient was a 52 year old male, who died of a malignant thymoma with multiple bone metastasis, extensive pleural carcinomatosis of the left lung and some metastatic nodules in the liver and the mesenterium. At autopsy, the proximal and middle portions of the penis were very hard. Macroscopically, the entire tunica albuginea of both the corpora cavernosa was markedly thickened, 2-4 mm; and calcified. Microscopically, the tunica albuginea showed extensive hyaline degeneration, calcification and ossifying foci with osteoblasts and osteoclasts. Inflammatory cells were frequently found beneath the thickened tunica albuginea. In the corpus cavernosum, cavernous arteries showed marked intimal thickening and medial muscular degeneration with a few inflammatory cells. Smooth muscles of the stroma were extensively atrophic and degenerative, and some of them were infiltrated with a few inflammatory cells. In the corpus spongiosum, the tunica albuginea was not thickened, but the smooth muscle in the stroma was atrophic and degenerative and a few inflammatory cells were also found. Surprisingly, there was no Littrés gland around the urethra. In Peyronies disease, the dorsal part of the penis is usually involved, and less frequently lateral or ventral sites are involved. The circumferential involvement of both the corpora cavernosa has not been reported until now, as far as the authors know.

Aesthetic activities and aesthetic attitudes: influences of education, background and personality on interest and involvement in the arts.

McManus, I C; Furnham, A

There have been few studies of why some people are frequently involved in aesthetic activities such as going to the theatre, reading or playing musical instruments, whereas others are less involved. This study assesses the broad roles of education, personality and demographic factors such as social class, age and sex. More aesthetic activity was associated with music and art education, whereas science education had a substantial negative relationship with aesthetic activity, both directly and also indirectly via reduced art education. More aesthetic activity was particularly related to higher scores on the personality factor of openness, and also to lower scores on agreeableness and conscientiousness. Higher parental social class was also associated with more aesthetic activity, as also was lower age. Sex had no relationship to aesthetic activity, as neither did masculinity-femininity. Positive aesthetic attitudes were also related moderately to aesthetic activity, but were particularly strongly related to openness to experience, and somewhat less to extraversion. Class, age and sex had no direct relationship to aesthetic attitudes.

The purpose of the study was to review the current evidence and design a diabetic macular edema (DME) management guideline specific for India. The published DME guidelines from different organizations and publications were weighed against the practice trends in India. This included the recently approved drugs. DME management consisted of control of diabetes and other associated systemic conditions, such as hypertension and hyperlipidemia, and specific therapy to reduce macular edema. Quantification of macular edema is precisely made with the optical coherence tomography and treatment options include retinal laser, intravitreal anti-vascular endothelial growth factors (VEGF), and implantable dexamethasone. Specific use of these modalities depends on the presenting vision and extent of macular involvement. Invariable eyes with center-involving macular edema benefit from intravitreal anti-VEGF or dexamethasone implant therapy, and eyes with macular edema not involving the macula center benefit from retinal laser. The results are illustrated with adequate case studies and frequently asked questions. This guideline prepared on the current published evidence is meant as a guideline for the treating physicians.

The Role of Mitochondria in Cancer Induction, Progression and Changes in Metabolism.

PubMed

Rogalinska, Malgorzata

2016-01-01

Mitochondria play important roles as energetic centers. Mutations in mitochondrial DNA (mtDNA) were found in several diseases, including cancers. Studies on cytoplasmic hybrids (cybrids) confirm that directed mutation introduced into mtDNA could be a reason for cancer induction. Mitochondria could also be a factor linking cancer transformation and progression. The importance of mitochondria in cancer also confirms their involvement in the resistance to treatment. Resistance to treatment of cancer cells can frequently be a reason for glycolysis acceleration. It could be explained by cancer cells' high proliferation index and high energy request. The involvement of mitochondria in metabolic disturbances of several metabolic diseases, including cancers, was reported. These data confirm that cancer induction, as well as cancer progression, could have metabolic roots. The aberrant products observed in prostate cells involved in the Krebs cycle could promote cancer progression. These multiple relationships between alterations on a genetic level translated into disturbances in cellular metabolism and their potential relation with epigenetic control of gene expression make cancerogenesis more complicated and prognoses' success in studies on cancer etiology more distant in time.

Mucocele is a lesion that involves the salivary glands and respective current ducts caused mainly by traumas in the affected area. Two different histological forms can be found: extravasation phenomenon and mucus-retention cyst where the former is the most frequently observed involving minor salivary glands such as the glands present in the anterior portion of the ventral surface of the tongue (glands of Blandin-Nuhn). This report describes a large lesion involving the ventral surface of the tongue that was definitively diagnosed by histological examination as extravasation mucocele. Important concepts are reviewed to help clinicians correctly diagnose and treat this pathology.

Cystic fibrosis is a degenerative disease characterized by progressive epithelial secretory gland dysfunction associated with repeated respiratory infections. Bacterial infections are very frequent in children with cystic fibrosis, but because rapid METHODS: for screening for the wide variety of potentially involved viruses were unavailable until recently, the frequency of viral presence is unknown. Multiplex PCR enables screening for many viruses involved in respiratory infections. This study aimed to evaluate the frequency of viruses and bacteria in respiratory specimens from children with cystic fibrosis and to clarify the incidence and characteristics (seasonality and age of patients) of different viruses detected in children with cystic fibrosis. In this 2-year prospective study, we obtained paired nasopharyngeal-swab and sputum specimens from children with cystic fibrosis during clinical respiratory examinations separated by at least 14days. We analyzed viruses in nasopharyngeal-swab specimens with multiplex PCR and bacteria in sputum with standard methods. We analyzed 368 paired specimens from 33 children. We detected viruses in 154 (41.8%) and bacteria in 132 (35.9%). Bacteria were commoner in spring and summer; viruses were commoner in autumn and winter. In every season, Staphylococcus aureus was the commonest bacteria and rhinovirus was the commonest virus. Nearly all infections with Haemophilus influenzae occurred in autumn and winter. Viruses were more prevalent in children <5 years old, and bacteria were more prevalent in children ≥12 years old. Multiplex PCR screening for respiratory viruses is feasible in children with cystic fibrosis; the clinical implications of screening warrant further study. Copyright © 2016 Elsevier B.V.

An update in prevention and treatment of pediatric obesity.

PubMed

Moya, Manuel

2008-08-01

Obesity prevalence is growing as well as its severity with increasing morbidity and mortality. This "globesity" also affects developing countries where under nutrition and stunting frequently coexist with overweight and obesity. One third of obese adults began to be so in the pediatric ages. There are two main types of prevention: general one representing greater actions from health authorities and the individual one carried out by the pediatrician and the patient at risk. Once the state of obesity is reached (relative body mass index, rBMI >121%) the longer lasting care becomes more complex and frequently unsuccessful. The treatment of obesity is aimed to care for the present and silent disorders and for preventing its further tracking to adulthood. Identification of pediatric population at risk which is the one with an rBMI of 111%-120% plus other risk factors. Specific individual actions include reduction of food intake, increase of energy expenditure, involvement of parents, and the child-adolescent himself in the prevention. Therapy is based on some principles plus the important medical and emotional approach. A Cochrane study based on only 10 appropriate studies showed a predominant poor efficacy of the undergone preventive action. Treatment guides are presented after our own experience with a group of 400 kids with an average follow-up of 7 years and other individual prevention studies. Involving motivated pediatricians with a minimum of time for visits and better follow-up in the frame of a general national preventive programme could be a rational outcome. Treatment of obesity should never be postponed whatever the clinical care is.

We aim to describe medical services provided by Nordic general practitioners (GPs), and to explore possible differences between the countries. We did a comparative analysis of selected data from the Nordic part of the study Quality and Costs of Primary Care in Europe. 875 Nordic GPs (198 Norwegian, 80 Icelandic, 97 Swedish, 212 Danish and 288 Finnish) answered identical questionnaires regarding their practices. The GPs indicated which equipment they used in practice, which procedures that were carried out, and to what extent they were involved in treatment/follow-up of a selection of diagnoses. The Danish GPs performed minor surgical procedures significantly less frequent than GPs in all other countries, although they inserted intrauterine devices significantly more often than GPs in Iceland, Sweden and Finland. Finnish GPs performed a majority of the medical procedures more frequently than GPs in the other countries. The GPs in Iceland reported involvement in a more narrow selection of conditions than the GPs in the other countries. The Finnish GPs had more advanced technical equipment than GPs in all other Nordic countries. GPs in all Nordic countries are well equipped and offer a wide range of medical services, yet with a substantial variation between countries. There was no clear pattern of GPs in one country doing consistently more procedures, having consistently more equipment and treating a larger diversity of medical conditions than GPs in the other countries. However, structural factors seemed to affect the services offered.

The incidence of Crohn's disease has been increasing in Western communities, but there are no published studies which have examined this change in children in Australia. The centralization of pediatric gastroenterology services in Victoria provides an opportunity to examine these changes within one state. We undertook a retrospective study over a 31-year period of all children aged 16 years or less initially diagnosed with Crohn's disease at either the Royal Children's Hospital, or Monash Medical Center, Melbourne, Victoria. We identified 351 patients who met the diagnostic criteria between 1971 and 2001. The incidence of Crohn's disease in children aged 16 years or less rose from 0.128 to 2.0 per 100,000 per year over the three decades (r = 0.964, P < 0.01). There was a disproportionate over-representation of children from an urban background (incidence rate ratio 1.66, 95% CI 1.28-2.16). Children currently being diagnosed had on average a lower erythrocyte sedimentation rate (ESR) and higher albumin than in previous decades. The use of flexible endoscopy has increased markedly (1970s: 60%; 1990s: 96%, P < 0.05) and the proportion of children recognized at diagnosis with upper gastrointestinal and colonic involvement has increased significantly. There has been a significant increase in the incidence of Crohn's disease in Victorian children. The pattern of disease has also changed with colonic disease now more frequent, and inflammatory indices less abnormal. The increased use of endoscopy has established the frequent involvement of the upper gastrointestinal tract.

To evaluate the hypertension associated to different types and sub-types of cerebrovascular disease (stroke), with particular reference to the frequency of hypertension, the values of blood pressure, the risk factors and the involvement of other target organs. Prospective study in 248 patients with acute stroke admitted to a Clinical Medicine Unit in three independent time periods. Internal Medicine Clinic of University Hospital in Lisbon. Medical, neurological and cardiologic examination were performed and all patients were also submitted to different complementary tests, including a computer tomography scan of the brain, and an echocardiogram. The values of blood pressure were measured in the admission at the urgent service and 24 h after in the the ward. We identified three sub-types of stroke: intracerebral hemorrhage (IH), ischaemic stroke (IS) and lacunes (L). For each sub-type and for those with hypertension or not, we evaluated: age, sex, duration of stay in hospital and mortality. We also compared for each sub-type the values of blood pressure, the risk factor and the repercussion on other target organs. Two hundred and forty eight patients (52% were men) with mean age 68.0 +/- 10.2 years, and ages among 40 and 92 years. Thirty-seven patients (15%) died. In the entire population (n = 248) hypertension were more prevalent in IH 83% and L 82% than in IS 59% (p < 0.0005). Hypertension was present in 172 patients (69%) and 81 (47%) were IS, 58 (34%) L and 33 (19%) IH. Sixty six percent of the 172 patients with hypertension had at least another risk factor and the most aged ones (> 65 years old) were more frequent in IS 75% than in HI 45% or L 58% (p < 0.001). For all subtypes blood pressure measurements were higher in admission than in ward and they were also higher in IH than in IS (p < 0.05). Hypertensive cardiopathy was more prevalent in IH 76% and L 61% than in IS 49% (p < 0.05). Renal failure was more frequent in IS 37% than in IH 28% and L 17% (p < 0.05). Hypertension is very frequent, and like advanced age is a major risk factor of stroke. Hypertension is frequently associated with one or more risk factors. Hypertensive cardiopathy is more related with IH and L and the renal involvement with IS.

The present study examined leisure activity and its association with caregiver involvement (i.e., residence and time spent with primary caregiver) in 62 middle-aged and older adults with Down syndrome (aged 30-53 years). Findings indicated that middle-aged and older adults with Down syndrome frequently participated in social and passive leisure activities, with low participation in physical and mentally stimulating leisure activities. Residence and time spent with primary caregiver were associated with participation in physical leisure activity. The findings suggest a need for support services aimed at increasing opportunities for participating in physical and mentally stimulating leisure activity by middle-aged and older adults with Down syndrome. These support services should partner with primary caregivers in order to best foster participation in physical leisure activity.

Previous research has suggested a link between athletic involvement and elevated levels of adolescent violence outside the sport context. The present study expanded on this literature by positing differences in the sport/violence relationship across dimensions of athletic involvement (athletic participation vs. jock identity), type of violence (family vs. nonfamily), and gender, as well as examining the impact of binge drinking on the sport/violence relationship. Regression analyses using a sample of 608 Western New York adolescents indicated that (1) jock identity (but not athletic participation) was associated with more frequent violence; (2) jock identity predicted nonfamily violence (but not family violence); and (3) the link between jock identity and nonfamily violence was stronger for boys than for girls. Binge drinking predicted family violence among nonjocks only. PMID:16399926

How the elderly and young adults differ in the decision making process of nonprescription medication purchases.

The study compared elderly and young adults in their behavior and involvement in the decision making process of over-the-counter (OTC) medication purchases. Elderly subjects were more involved in the decision making process to purchase OTC medications compared to young adults. The elderly not only purchase and spend more money on medications but also read OTC labels completely. They requested help from the pharmacist more frequently than young adults. Needs of the elderly in making an OTC medication purchase were different compared to young adults. The two age groups differed on importance rating for several attributes regarding OTC medications, such as; ease of opening the package, child resistant package, side effects of medicine, manufacturer of medicine, print size on package labels, and greater choice of medicine.

A Reasoned Action Model of Male Client Involvement in Commercial Sex Work in Kibera, A Large Informal Settlement in Nairobi, Kenya.

Male clients of female sex workers (FSWs) are epidemiologically important because they can form bridge groups linking high- and low-risk subpopulations. However, because male clients are hard to locate, they are not frequently studied. Recent research emphasizes searching for high-risk behavior groups in locales where new sexual partnerships form and the threat of HIV transmission is high. Sub-Saharan Africa public drinking venues satisfy these criteria. Accordingly, this study developed and implemented a rapid assessment methodology to survey men in bars throughout the large informal settlement of Kibera, Nairobi, Kenya, with the goal of delineating cultural and economic rationales associated with male participation in commercial sex. The study sample consisted of 220 male patrons of 110 bars located throughout Kibera's 11 communities. Logistic regression analysis incorporating a modified Reasoned Action Model indicated that a social norm condoning commercial sex among male peers and the cultural belief that men should practice sex before marriage support commercial sex involvement. Conversely, lacking money to drink and/or pay for sexual services were barriers to male commercial sex involvement. Results are interpreted in light of possible harm reduction programs focusing on FSWs' male clients.

Aggressive interactions during free-play at preschool of children with and without developmental coordination disorder.

This aim of this study was to investigate an unexpected finding from a larger study examining the play of preschool children with and without developmental coordination disorder (DCD). We found that children with DCD were more frequently involved in aggressive incidents during free-play than their peers. Children with (n=32) and without DCD (n=31) were videotaped during free-play at preschool and their play was assessed using the Play Observation Scale. A post hoc analysis was conducted using a specifically developed rating instrument to examine the aggressive incidents captured on video. Videos from 18 children with DCD and 8 typically developing children without DCD were found to contain aggressive incidents. Children with DCD were significantly more often involved as both aggressor (p=.016) and victim (p=.008) than children without DCD (p=.031). This is the first study to identify victimization and aggression as being problematic for children with DCD as young as 4 years of age and needs replication. Given the negative consequences of involvement in aggression and victimization, play-based early intervention focusing on prevention needs to be developed and implemented.

The aim of this study was to determine the correlation between tuberculous meningitis and tuberculous otomastoiditis. Meningeal involvement sites were investigated by magnetic resonance imaging in 32 patients (21 males, 11 females) who had previously been diagnosed with tuberculous meningitis. Clinical and laboratory findings and responses to anti-tuberculous treatment were evaluated, and the presence of concomitant tuberculous otomastoiditis was also investigated. The meningeal involvement site was unilateral (in the sylvian fissure and the perimesencephalic cistern) in 28 patients (87.5 per cent), and bilateral and widespread in four patients (12.5 per cent). Tuberculous otomastoiditis was found in 11 of the patients with tuberculous meningitis (34.3 per cent). Otomastoiditis was on the same side as the meningeal involvement in nine of these 11 patients. Bilateral otomastoiditis with meningeal involvement was observed in two patients. Tuberculous meningitis is frequently accompanied by otomastoiditis, although the exact causal relationship between the two conditions is unclear. Since meningitis is a serious clinical condition, concomitant otomastoiditis generally remains unrecognised. Tuberculosis should be considered in the differential diagnosis of patients with otitis or otomastoiditis who do not respond to antibiotic therapy.

Risky driving and lifestyles in adolescence.

Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use.

Tic disorders constitute a neurodevelopmental disorder of childhood. This study sought to determine the prevalence of tic disorders in a school-based sample. A randomized sample of 1158 schoolchildren, based on clusters (classrooms) in the province of Burgos (Spain), was identified on a stratified sampling frame combining types of educational center and setting (mainstream schools and special education), using a two-phase approach (screening and diagnosis ascertainment by a neurologist). Tics with/without impairment criterion were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders criteria. In mainstream schools, tics were observed in 125/741 students (16.86%; 95% confidence interval, 14.10-19.63), and were more frequent in boys (87/448, 19.42%; 95% confidence interval, 15.64-23.19) compared with girls (38/293, 12.96%; 95% confidence interval, 8.95-16.98; P = 0.03). In special education centers, tics disorders were observed in 11/54 of children (20.37%; 95% confidence interval, 8.70-32.03). Overall, tics with impairment criteria were less frequent than tics without impairment criteria (4.65% vs 11.85%, P < 0.0001). The most frequent diagnoses involved chronic motor tics (6.07%) and Tourette syndrome (5.26%). Tic disorders are common in childhood, and the use or nonuse of impairment criteria exerts a significant impact on tic prevalence estimates. Copyright © 2011 Elsevier Inc. All rights reserved.

Systemic lupus erythematosus (SLE) is a systemic disease of connective tissue with broad band of symptoms. It could be the reason for many organs and tissues impairment. Changes in eyes that occurr in SLE are not frequent, but can lead to severe impairment of sight including blindness. The aim of the work was to asses the frequency of eye changes among patients with SLE and SLE with antiphospholipid syndrome (APS). Another aim was to asses the association between antiphospholipid antibodies and ocular lesions. There were 75 patients enrolled with SLE, 26 of them ha APS. All of patients had a comprehensive ophthalmological and physical examination. Moreover biochemica analysis including lipid profile and glucose metabolism and serological markers of APS and SLE were performe Thirty-six patients complained of ophthalmologic disturbances (48%), with "dry eyes" being the most common symptom (20 patients). The reduced visual acuity was detected in 17 patients (22.6%). Conjunctivitis was found in 8 patients (10.67%), corneal involvement in 31 (41.3%), and sclera changes in 40 patients (53.3%). Changes in retina were found in 15 (20%) of patients, the most frequent were sub-retinal edema in the region of yellow spot. Changes in yellow spot were found in 8 patients; in 2 of them it was associated with dry degenerative changes, in 6 patients exudates with or without hemorrhages were found. Vascular changes including their lumen diameter were found in 33 patients (44%). In 4 patients there were changes in optical nerve disc. Schirmer's test was pathological in 43 patients (57.3%), but in only 4 patients Sjögren's syndrome was diagnosed. In the group of SLE patients intraocular pressure was significantly higher. The presence of anticardiolipin antibodies IgG class (aCL IgG) was associated with reduced visual acuity. The presence of lupus anticoagulant and anti-beta2, glycoprotein-I antibodies (anti-beta2GPI) was associated with conjunctive involvement. The presence of aCL IgM and anti-beta2GPI was associated with less frequent symptoms of eye dryness. We found the following significant factors of the occurrence of eye involvement in our series of SLE patients: high activity of disease (conjuctiva, iris, uvea, retina, spot, vessels and optical nerve disc involvement), late diagnosis of SLE (retinopathy and conjuctive involvement), arterial hypertension (reduced visual acuity, cornea involvement, vessels involvement), age (reduced visual acuity, cornea involvement, retinopathy), glucose metabolism disorders (changes in optical nerve disc) and presence of anti-double stranded DNA antibodies (retinopathy).

Hemodialysis Hospitalizations and Readmissions: The Effects of Payment Reform

PubMed Central

Erickson, Kevin F.; Winkelmayer, Wolfgang C.; Chertow, Glenn M.; Bhattacharya, Jay

2016-01-01

Background In 2004 the Centers for Medicare & Medicaid Services (CMS) changed reimbursement for physicians and advanced practitioners caring for patients receiving hemodialysis from a capitated to a tiered fee-for-service system, encouraging increased face-to-face visits. This early version of a pay-for-performance initiative targeted a care process: more frequent provider visits in hemodialysis. While more frequent provider visits in hemodialysis are associated with fewer hospitalizations and re-hospitalizations, it is unknown whether encouraging more frequent visits through reimbursement policy also yielded these benefits. Study Design We used a retrospective cohort, interrupted time-series study design to examine whether the 2004 nephrologist reimbursement reform led to reduced hospitalizations and re-hospitalizations. We also used published data to estimate a range of annual economic costs associated with more frequent visits. Setting & Participants Medicare beneficiaries in the United States receiving hemodialysis in the two years prior to and following reimbursement reform. Predictor The two years following nephrologist reimbursement reform. Outcomes Odds of hospitalization and 30-day hospital readmission for all causes and fluid overload; US dollars. Results We found no significant change in all-cause hospitalization or re-hospitalization, and slight reductions in hospitalization and re-hospitalization for fluid overload following reimbursement reform; the estimated economic cost associated with additional visits ranged from $13 to $87 million per year, depending on who (physicians or advanced practitioners) spent additional time visiting patients and how much additional effort was involved. Limitations Due to limited information about how much additional time providers spent seeing patients after reimbursement reform, we could only examine a range of potential economic costs associated with the reform. Conclusions A Medicare reimbursement policy designed to encourage more frequent visits during outpatient hemodialysis may have been costly. The policy was associated with fewer hospitalizations and re-hospitalizations for fluid overload, but had no effect on all-cause hospitalizations or re-hospitalizations. PMID:27856087

Voxel-based morphometry (VBM) and diffusion tensor imaging (DTI) are the most implemented methodologies to detect alterations of both gray and white matter (WM). However, the role of WM in mental disorders is still not well defined. We aimed at clarifying the role of WM disruption in schizophrenia and at identifying the most frequently involved brain networks. A systematic literature search was conducted to identify VBM and DTI studies focusing on WM alterations in patients with schizophrenia compared to control subjects. We selected studies reporting the coordinates of WM reductions and we performed the anatomical likelihood estimation (ALE). Moreover, we labeled the WM bundles with an anatomical atlas and compared VBM and DTI ALE-scores of each significant WM tract. A total of 59 studies were eligible for the meta-analysis. WM alterations were reported in 31 and 34 foci with VBM and DTI methods, respectively. The most occurred WM bundles in both VBM and DTI studies and largely involved in schizophrenia were long projection fibers, callosal and commissural fibers, part of motor descending fibers, and fronto-temporal-limbic pathways. The meta-analysis showed a widespread WM disruption in schizophrenia involving specific cerebral circuits instead of well-defined regions. Copyright © 2017 Elsevier B.V. All rights reserved.

Pain originating from the sacroiliac joint is a common non-traumatic musculoskeletal complaint in elite inline-speedskaters - an observational study

PubMed Central

2012-01-01

Study design Observational study Objectives To investigate common non-traumatic musculoskeletal complaints of the low back in elite inline-speedskaters of the German national team. Summary of background data Traumatic injuries associated with falls or collisions are well documented in speedskaters but so far no studies have investigated non-traumatic low back pain. Previously, the sacroiliac joint was suspected as a frequent origin of complaint, we aimed to investigate this assumption. Methods Two chiropractors examined elite inline-speedskaters of the German national team during three sports events between summer 2010 and 2011. A test cluster of five provocative tests for the sacroiliac joint was selected based on reliability and validity. Results A total of 37 examinations were conducted on 34 athletes with low back pain during the three sport events. The reported pain intensities ranged from mild to moderate pain (VAS 23.4 ± 13.4 to 35.1 ± 19.2). About 90% of cases showed involvement of the SI joint of which again 90% presented with left sided symptoms. Conclusions Non-traumatic complaints of the low back originating from the left sacroiliac joint frequently occur in competitive inline speedskaters. PMID:22404796

BACKGROUND: Pharmaceutical industry-sponsored research has been shown to be biased toward reporting positive results. Frequent industry participation in trials assessing the efficacy of inhaled corticosteroid (ICS) and long-acting beta2-agonist (LABA) combination treatment makes assessing industry influence difficult and warrants an assessment of specific potential publication bias in this area. OBJECTIVE: To describe the frequency of industry involvement in ICS/LABA trials and explore associations among significant outcomes, type of industry involvement and type of primary outcome. METHODS: A systematic review of trials comparing ICS/LABA combination therapy with ICS monotherapy for asthma was conducted. Data concerning the type of industry sponsorship, primary outcome and statistical results were collected. Comparisons between type of sponsorship and significant results were analyzed using Pearson’s χ2 test and relative risk. RESULTS: Of 91 included studies (median year of publication 2005 [interquartile range 1994 to 2008]), 86 (95%) reported pharmaceutical involvement. Author affiliation was reported in 49 of 86 (57%), and 19 of 86 (22%) were industry-reported trials without full publications. The remainder were published journal articles. Studies with a first or senior author affiliated with industry were 1.5 times more likely to report statistically significant results for the primary outcome compared with studies with other types of industry involvement. Pulmonary measures were 1.5 times more likely to be statistically significant than were measures of asthma control. CONCLUSIONS: The potential biases identified were consistent with other research focused on author role and industry involvement, and suggest that degree of bias may vary with type of affiliation.

2013-06-01

To date only 38 cases of childhood-onset eosinophilic granulomatosis with polyangiitis (cEGPA; formerly Churg-Strauss syndrome) have been reported. Additional patients with cEGPA could enhance the understanding of this rare and life-threatening condition. Our objectives were (1) to determine the frequency of specific organ system involvement; (2) to examine initial therapeutic regimen; and (3) to document disease and therapy-related morbidity in a contemporary cohort of patients with cEGPA. Retrospective review of patients evaluated at the Cleveland Clinic between 2003 and 2011 who met either American College of Rheumatology or Lanham criteria for EGPA and whose age was < 18 years at symptom onset. Nine patients (8 female; 7 white) were identified. Median age at onset of rhinitis/asthma symptom was 13 years and median age at diagnosis of cEGPA was 15 years. All patients demonstrated eosinophilia, upper airway disease (allergic rhinitis, chronic sinusitis, and/or nasal polyps), and pulmonary involvement. Other frequently involved organ systems included musculoskeletal (67%), gastrointestinal (67%), cutaneous (67%), neurologic (56%), and cardiac (44%). Antineutrophil cytoplasmic antibody (ANCA) serologies were negative in all patients. The medications used most frequently for initial therapy included oral (44%) or intravenous corticosteroids (56%) and azathioprine (67%). Disease or therapeutic complications occurred in half of the cohort and included heart failure, stroke, and sequela from longterm, high-dose steroids. Eosinophilia, in combination with upper airway, pulmonary, musculoskeletal, neurologic, and cardiac manifestations, is frequently observed in cEGPA. ANCA titers are often negative. Steroids are the mainstay of initial therapy but steroid-related side effects occur regularly.

Work-related injuries in children and adolescents represent a negative indication of more general inequities of the society in which events occur. Their characteristics are not well described, particularly in Italy, and this paper is aimed at highlighting some fundamental aspects of these injuries. The case in point is represented by the injuries that received compensation and occurred in the Lombardy Region (Italy) between 1984 and 1989 and involved people under the age of eighteen. The injuries occurring in the same period and area in workers over eighteen were used for comparison. Work related injuries in minors were more frequent in crafts activities than in industry, but their gravity (in terms of deaths or permanent consequences) was lower than in the corresponding adult workers. Ninety percent of the events in young workers occurred in males, in each age category, and about 5% of the cases pertains to very young workers (less than 15 years). Cuts/lacerations are the most frequent type of lesion (49.9%) and the hands represent the site most frequently involved (55.5%). The great majority of the observed injuries pertains to a limited number of economic activity sectors: about 75% of the cases occurred in ten sectors. Metal manufacturing, construction and machine production scored first, with interesting correlations with the same sectors in adult workers. Ten specific occupations represent over fifty percent of the cases, with mechanics and bricklayers at the top. The description of the accident in terms of mode of occurrence and the agents involved was less informative and not specific.(ABSTRACT TRUNCATED AT 250 WORDS)

Background & objectives: Epidemiological interventions and mosquito control are the available measures for dengue control. The former approach uses serotype and genetic information on the circulating virus strains. Dengue has been frequently reported from Nepal, but this information is mostly lacking. The present study was done to generate a comprehensive clinical and virological picture of a dengue outbreak in Nepal during 2013. Methods: A hospital-based study involving patients from five districts of Nepal was carried out. Demographic information, clinical details and dengue serological status were obtained. Viral RNA was characterized at the molecular level by reverse-transcription polymerase chain reaction (RT-PCR), nucleotide sequencing and phylogenetic analysis. Results: From among the 2340 laboratory-confirmed dengue cases during the study period, 198 patients consented for the study. Clinically they had fever (100%), headache (59.1%), rashes (18.2%), retro-orbital pain (30.3%), vomiting (15.1%), joint pain (28.8%) and thrombocytopenia (74.3%). Fifteen (7.5%) of them had mucosal bleeding manifestations, and the rest were uncomplicated dengue fever. The patients were mostly adults with a mean age of 45.75 ± 38.61 yr. Of the 52 acute serum samples tested, 15 were positive in RT-PCR. The causative virus was identified as DENV serotype 2 belonging to the Cosmopolitan genotype. Interpretations & conclusions: We report here the involvement of DENV serotype 2 in an outbreak in Nepal in 2013. Earlier outbreaks in the region in 2010 were attributed to serotype 1 virus. As serotype shifts are frequently associated with secondary infections and severe disease, there is a need for enhancing surveillance especially in the monsoon and post-monsoon periods to prevent large-scale, severe dengue outbreaks in the region.

The study aim was to identify risk factors for collisions/near-collisions involving on-road commuter cyclists and drivers. A naturalistic cycling study was conducted in Melbourne, Australia, with cyclists wearing helmet-mounted video cameras. Video recordings captured cyclists’ perspective of the road and traffic behaviours including head checks, reactions and manoeuvres. The 100-car naturalistic driving study analysis technique was adapted for data analysis and events were classified by severity: collision, near-collision and incident. Participants were adult cyclists and each filmed 12 hours of commuter cycling trips over a 4-week period. In total, 127 hours and 38 minutes were analysed for 13 participants, 54 events were identified: 2 collisions, 6 near-collisions and 46 incidents. Prior to events, 88.9% of cyclists travelled in a safe/legal manner. Sideswipe was the most frequent event type (40.7%). Most events occurred at an intersection/intersection-related location (70.3%). The vehicle driver was judged at fault in the majority of events (87.0%) and no post-event driver reaction was observed (83.3%). Cross tabulations revealed significant associations between event severity and: cyclist reaction, cyclist post-event manoeuvre, pre-event driver behaviour, other vehicle involved, driver reaction, visual obstruction, cyclist head check (left), event type and vehicle location (p<0.05). Frequent head checks suggest cyclists had high situational awareness and their reactive behaviour to driver actions led to successful avoidance of collisions/near-collisions. Strategies to improve driver awareness of on-road cyclists and to indicate early before turning/changing lanes when sharing the roadway with cyclists are discussed. Findings will contribute to the development of effective countermeasures to reduce cyclist trauma. PMID:21050610

To explore staff responses, in terms of common practices, towards partnered sexual relationships in long-term care facilities where one or both people involved have dementia. It also tries to determine personal and institutional factors influencing these responses. Although some studies, mostly qualitative, have focused on reactions to residents' sexual expressions so far the issue has not been assessed in a study using large and diverse samples. Cross-sectional quantitative study using vignette technique. Participants were 2,295 staff members at 152 Spanish long-term care facilities. Data were collected during 2016. A vignette describing sexual situations involving people with dementia was presented to participants. After the vignette, participants had to answer the question: "What do you think most of your colleagues would do in this situation?" with nine possible responses. Results showed that relationships involving persons with dementia were perceived as potentially problematic by staff. In both conditions, discussing the case with a colleague or supervisor was the most frequently chosen reaction. More restrictive reactions were mentioned when only one person with dementia was involved in the relationship. Factors such as participants" age and years of experience, professional post and commitment to person-centred care practices were related with the frequency of common restriction practices. Results highlight the importance of providing staff with clear guidelines regarding the management of specific sexual situations to avoid stereotyped restrictive reactions. © 2017 John Wiley & Sons Ltd.

Chronic periaortitis (CP) is a rare disease characterized by fibro-inflammatory tissue surrounding the abdominal aorta and the iliac arteries. Anecdotal reports have shown that CP may also involve other vascular districts, particularly the thoracic aorta. The aim of this study was to investigate the thoracic aorta and epiaortic artery involvement in CP. Patients were eligible if they had undergone imaging studies assessing inflammatory involvement of the thoracic aorta and its major branches (e.g. contrast CT, MRI or PET-CT). We explored the patterns of thoracic vessel involvement and compared the clinical characteristics of patients with and without thoracic disease. Where available, we also reviewed the thoracic vascular/perivascular tissue biopsies. Of 153 CP patients seen between 1999 and 2012, 77 were eligible. Of these, 28 (36%) had thoracic involvement: 15 (54%) had thoracic periaortitis, with 7 also showing epiaortic artery involvement; 6 (21%) had periaortitis surrounding a thoracic aortic aneurysm, 2 of them with epiaortic artery involvement; 7 (25%) had a thoracic aortic aneurysm without periaortitis. Patients with thoracic disease were more frequently female (P = 0.01), were older (P = 0.001) and had a higher frequency of pain and constitutional symptoms (P = 0.02). Thoracic (peri)vascular biopsies revealed adventitial and peri-adventitial fibro-inflammatory patterns similar to those observed in abdominal CP. In about one-third of patients, CP also involves the thoracic aorta and the epiaortic arteries, which supports the hypothesis of a systemic inflammatory disease of the large arteries. © The Author 2015.

Lesar, Timothy S

2002-01-01

CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

Trauma on eight wheels. A study of roller skating injuries in Seattle.

1983-01-01

Thirty-five fractures secondary to roller skating accidents from March 15 to October 1, 1979 were treated in the University of Washington-affiliated hospitals. Twenty-eight involved the wrist and elbow. Only three were in skeletally immature individuals. Sixty-three percent of the patients were female with the 20- to 34-year-old age group the most commonly involved. A fall, usually backwards, onto outstretched arms and hands was the most frequent mechanism of injury. A detailed study of the popular outdoor skating area in Seattle, Green Lake, indicated that more than 75% of the injuries occurred on sloped surfaces with otherwise favorable environmental conditions. Most people were either first time skaters or had not skated since childhood. Based on our study, we recommend: (1) skating on level, familiar terrain; (2) learning to skate in a sparsely congested area; (3) skating with experienced partners who can give instructions; and (4) using protective equipment, such as knee and elbow pads and rigid wrist splints.

Protocol evaluation for effective music therapy for persons with nonfluent aphasia.

2008-01-01

Although the notion of the language specificity of neural correlates has been widely accepted in the past (e.g., lefthemispheric dominance including Broca's and Wernike's area, N400 ERP component of semantic processing, and the P600 ERP component of syntactic processing, etc.), recent studies have shown that music and language share some important neurological aspects in their processing, both involving bilateral hemispheric activities. In line with this are the frequent behavioral clinical observations that persons with aphasia show improved articulation and prosody of speech in musically assisted phrases. Connecting recent neurological findings with clinical observations would not only inform clinical practice but would enhance understanding of the neurological mechanisms involved in the processing of speech/language and music. This article presents a music therapy treatment protocol study of 7 nonfluent patients with aphasia. The data and findings are discussed with regard to some of the recent focuses and issues addressed in the experimental studies using cognitive-behavioral, electrophysiological, and brain-imaging techniques.

The present study comprised sarcomeric genotyping of the three most commonly involved sarcomeric genes: MYBPC3, MYH7, and TNNT2 in 192 unrelated Egyptian hypertrophic cardiomyopathy (HCM) index patients. Mutations were detected in 40 % of cases. Presence of positive family history was significantly (p=0.002) associated with a higher genetic positive yield (49/78, 62.8 %). The majority of the detected mutations in the three sarcomeric genes were novel (40/62, 65 %) and mostly private (47/62, 77 %). Single nucleotide substitution was the most frequently detected mutation type (51/62, 82 %). Over three quarters of these substitutions (21/27, 78 %) involved CpG dinucleotide sites and resulted from C>T or G>A transition in the three analyzed genes, highlighting the significance of CpG high mutability within the sarcomeric genes examined. This study could aid in global comparative studies in different ethnic populations and constitutes an important step in the evolution of the integrated clinical, translational, and basic science HCM program.

Accident history, risk perception and traffic safe behaviour.

PubMed

Ngueutsa, Robert; Kouabenan, Dongo Rémi

2017-09-01

This study clarifies the associations between accident history, perception of the riskiness of road travel and traffic safety behaviours by taking into account the number and severity of accidents experienced. A sample of 525 road users in Cameroon answered a questionnaire comprising items on perception of risk, safe behaviour and personal accident history. Participants who reported involvement in more than three accidents or involvement in a severe accident perceived road travel as less risky and also reported behaving less safely compared with those involved in fewer, or less severe accidents. The results have practical implications for the prevention of traffic accidents. Practitioner Summary: The associations between accident history, perceived risk of road travel and safe behaviour were investigated using self-report questionnaire data. Participants involved in more than three accidents, or in severe accidents, perceived road travel as less risky and also reported more unsafe behaviour compared with those involved in fewer, or less severe accidents. Campaigns targeting people with a less serious, less extensive accident history should aim to increase awareness of hazards and the potential severity of their consequences, as well as emphasising how easy it is to take the recommended preventive actions. Campaigns targeting those involved in more frequent accidents, and survivors of serious accidents, should address feelings of invulnerability and helplessness.

The play behavior, defined as interaction with peers and objects, of five autistic children was systematically observed in four environments, i.e., a stark environment, a theraplay unit, a playroom, and an outside play deck. The preliminary results suggested that (1) with some children environment has little or no effect on their play behavior; (2) with multiple objects, autistic children frequently related to the objects rather than to their peers; (3) object play was most frequently at the manipulative stage and often included repetitive and negative behavior; (4) within a confined space with no objects present, autistic children frequently engaged in solitary repetitive behavior; and (5) within a confined space designed to facilitate a movement flow (theraplay), autistic children modeled and imitated and were involved in gross motor play together.

Complex regional pain syndrome (CRPS) involves severe pain and it is difficult to identify the exact cause or pathogenesis. Therefore, there are controversies regarding legal issues related to the establishment of damage in medical malpractice lawsuits involving CRPS. This study aimed to analyze malpractice lawsuits involving CRPS, which occurred after the disputed medical treatment, to provide information on the courts' opinion and characteristics of the cases. This study analyzed 23 lawsuit judgments involving CRPS that were sentenced from 2005 to 2015. A total of 12 of the 23 cases were partially ruled in favor of the plaintiff. The average amount (KRW) claimed was 470,638,385 ± 860,634,092 (21,000,000 to 4,020,000,000), and that awarded was 72,906,843 ± 53,389,367 (15,000,000 to 181,080,803). Sixteen of the 23 cases had CRPS type I. In 11 of 23 cases, the site of the pain was located in the lower limb and in 14 cases there was no presence of trauma or event prior to medical treatment. Nerve injury was the most frequent reason for taking responsibility in compensating damage in malpractice cases involving CRPS. Physicians should consider various possibilities of such complications in medical practices. It is important to identify and improve areas which need to be improved for patient safety through analyzing the lawsuit judgment cases. © 2018 The Korean Academy of Medical Sciences.

2011-01-01

Background: Sarcoidosis is a systemic granulomatous disorder of unknown cause that occurs among men and women of all races. In the United States, black women are most frequently and most severely affected. There have been few epidemiologic studies of sarcoidosis focusing on black women. Methods: In this article, we present data on incidence, prevalence, and clinical characteristics of sarcoidosis among participants in the Black Women’s Health Study, a cohort study of 59,000 black women from across the United States. Data on incident disease and potential risk factors are obtained through biennial questionnaires. Follow-up has been > 80% through six completed cycles. Results: There were 685 prevalent cases of sarcoidosis at baseline in 1995 and 435 incident cases reported during 611,585 person-years of follow-up through 2007, for an average annual incidence rate of 71/100,000 and a current prevalence of 2.0%. The sarcoid diagnosis was confirmed in 96% of self-reported cases for whom medical records or physician checklists were obtained. The most frequently affected site was the lung. Most patients also had extrapulmonary involvement, with the most common sites being lymph nodes, skin, and eyes. Prednisone had the highest prevalence of use, followed by inhaled corticosteroids. Conclusions: This study confirms previous reports of high incidence and prevalence of sarcoidosis among black women, as well as the extent of extrapulmonary disease, frequent need for steroid therapy, and comorbid conditions in this population. The prospective identification of sarcoidosis cases from a defined population will enable a valid assessment of risk factors for incident disease as follow-up continues. PMID:20595459

2014-01-01

Background: Periapical lesions (PLs) occur as a result of pulpal inflammation and may rarely be seen in the absence of pulpal diseases. They are the most common pathological lesions affecting the alveolar bone. Objective: This study aims to describe the clinicopathological features of PLs of the jaws with emphasis on the two most common types. Methods: Histopathology records of PLs diagnosed from January 1990 to December 2012 at the Department of Oral Pathology, University College Hospital Ibadan, were examined and categorized into periapical cysts (PCs); periapical granuloma (PGs) and others. Clinical data and histopathological features of these PLs were reviewed and analyzed. Results: One hundred and four lesions met the criteria for this study and consisted of PGs with 71 (68.3%) cases and PCs with 31 (29.8%) cases and one case each of apical scar and pleomorphic adenoma. Age range of cases was 9 to 80 years (mean=35.6 ± 15.8years) with a peak at age group of 20-29 years. Females were more frequently affected with 51.9% of cases. PLs were most frequently diagnosed in the anterior maxillary region with 58 (56.9%) cases, while the most frequently involved tooth was the left maxillary central incisor with 23 (22.1%) cases. Conclusion: Findings in this study are consistent with those of previous studies. It is important for all periapical pathological specimens to be submitted for histological examination to establish an accurate diagnosis and aid in the identification of sinister lesions that may present in the Periradicular region of teeth.

Clinical presentation of pituitary adenomas frequently involves pain, particularly headache, due to structural and functional properties of the tumour. Our aim was to investigate the clinical characteristics of pain in a large cohort of patients with pituitary disease. In a cross-sectional study, we assessed 278 patients with pituitary disease (n=81 acromegaly; n=45 Cushing's disease; n=92 prolactinoma; n=60 non-functioning pituitary adenoma). Pain was studied using validated questionnaires to screen for nociceptive vs neuropathic pain components (painDETECT), determine pain severity, quality, duration and location (German pain questionnaire) and to assess the impact of pain on disability (migraine disability assessment, MIDAS) and quality of life (QoL). We recorded a high prevalence of bodily pain (n=180, 65%) and headache (n=178, 64%); adrenocorticotropic adenomas were most frequently associated with pain (n=34, 76%). Headache was equally frequent in patients with macro- and microadenomas (68 vs 60%; P=0.266). According to painDETECT, the majority of the patients had a nociceptive pain component (n=193, 80%). Despite high prevalence of headache, 72% reported little or no headache-related disability (MIDAS). Modifiable factors including tumour size, genetic predisposition, previous surgery, irradiation or medical therapy did not have significant impact neither on neuropathic pain components (painDETECT) nor on headache-related disability (MIDAS). Neuropathic pain and pain-related disability correlated significantly with depression and impaired QoL. Pain appears to be a frequent problem in pituitary disease. The data suggest that pain should be integrated in the diagnostic and therapeutic work-up of patients with pituitary disease in order to treat them appropriately and improve their QoL. © 2014 European Society of Endocrinology.

A case-control study, high-frequency cases were defined as those involving patients with a percentile >75 with regard to the frequency of spontaneous use of outpatient facilities in the last 12 months; controls were defined as those with a percentile <25. A multiple correspondence analysis was used to describe patient profiles, and the influences of depression and anxiety on frequent attendance was determined via logistic regression. Among the 780 participating patients, differences in the profiles among frequent users and controls were related to predisposing factors such as sex, age, and education, capacity factors such as the time required to visit the institution and the means of transport used, and need factors such as health perceptions, social support, family function, and the presence of anxiety or depressive disorders. A depression or anxiety disorder was found to associate positively with frequent attendance (adjusted odds ratio [aOR]: 1.99, 95% confidence interval [CI]: 1.19-3.31) and a referral system (aOR: 1.61, 95% CI: 1.01-2.76), but negatively with mild or no family dysfunction (aOR: 0.79; 95% CI: 0.48-0.88) after adjusting for age, sex, ethnicity, and health service-providing institutions. The profiles of high-frequency patients differ from control patients with respect to factors related to capacity, need, and willingness; in particular, the latter were independently associated with frequent attendance. Notably, the presence of an anxious or depressive disorder doubled the risk of highfrequency attendance at a primary care facility.

Uveitis can be a local eye disease or a manifestation of systemic rheumatologic disorders. However, the differences of clinical manifestations between uveitis patients with or without systemic rheumatologic disease have been seldom described in literature. We investigated the clinical features and complications of rheumatic disease-related uveitis, and compared the characteristics in patients with and without rheumatic disease in a Chinese population in Taiwan. A retrospective review was performed for all patients who had been diagnosed with uveitis between January 2009 and June 2014 at the Department of Ophthalmology, Chang Gung Memorial Hospital, Taoyuan, Taiwan. A total of 823 uveitis patients were enrolled in the study, including 123 patients with rheumatic diseases. The most frequent rheumatic diseases included ankylosing spondylitis (5.8%), followed by Behçet's disease (2.8%), sarcoidosis (1.4%), psoriasis (1.1%), and juvenile idiopathic arthritis (1.1%). Compared with patients without rheumatic disease, those with rheumatic disease-related uveitis had a lower mean age at onset (35.1 ± 15.8 years vs. 44.0 ± 17.5 years), a longer follow-up period (27.1 ± 25.3 months vs. 22.2 ± 23.0 months), a higher incidence of anterior uveitis (69.0% vs. 46.3%), less frequent posterior uveitis (4.9% vs. 21.4%), a higher incidence of recurrence (26.8% vs. 14.1%), more frequent bilateral involvement (53.7% vs. 38.8%), and more frequent posterior synechiae (17.2% vs. 9.4%). The disease course and clinical manifestations of rheumatic disease-related uveitis were different from those unrelated. Patients with rheumatic disease-related uveitis had a higher recurrent rate and more frequent posterior synechiae than patients without rheumatic diseases. Copyright © 2015.

2001-01-01

Drug therapy may be effective in controlling symptoms but the frequent coexistence of endometriosis and the lack of controlled studies make their efficacy difficult to quantify. Danazol IUD has been shown to reduce symptoms. Conservative surgery involving endomyometrial ablation, laparoscopic myometrial electrocoagulation or excision has proven to be effective in more than 50% of patients, although follow up has been restricted to three years. Arterial uterine artery embolization is a new technique which may be tried before considering hysterectomy. Hysterectomy may still be necessary in severe cases of adenomyosis. PMID:18493552

2017-01-01

Background/Aim: Ovarian cancer remains one of the most commonly encountered malignancies affecting women worldwide, that is unfortunately commonly diagnosed in advanced stages of the disease. In these stages, the tumoral process usually involves the surrounding viscera throughout contiguity or induces the apparition of distant metastases via peritoneal, lymphatic or hematogenous spread, multiple resections being needed in order to achieve a good control of the disease. Patients and Methods: In the present study, we present a case series of 12 patients in whom various surgical procedures on the rectosigmoidian loop were performed in order to achieve debulking surgery to no residual disease. Results: Digestive tract resections consisted of rectosigmoidian resection with left colostomy in three cases, low rectosigmoidian resections with anastomosis in eight cases and a stripping procedure of the peritoneal layer in one case. Conclusion: Due to the close proximity of the digestive and gynecological tract, advanced-stage ovarian tumors frequently involve the rectosigmoidian loop, imposing association of digestive tract surgical procedures.

Himle, Joseph A; Taylor, Robert Joseph; Chatters, Linda M

2012-05-01

Prior research is equivocal concerning the relationships between religious involvement and obsessive-compulsive disorder (OCD). The literature indicates limited evidence of denomination differences in prevalence of OCD whereas findings regarding OCD and degree of religiosity are equivocal. This study builds on prior research by examining OCD in relation to diverse measures of religious involvement within the National Survey of American Life, a nationally representative sample of African American and Black Caribbean adults. Bivariate and multivariate analyses (logistic regression) examine the relationship between lifetime prevalence of OCD and religious denomination, service attendance, non-organizational religiosity (e.g., prayer, religious media) subjective religiosity, and religious coping. Frequent religious service attendance was negatively associated with OCD, whereas Catholic affiliation (as compared to Baptist) and religious coping (prayer when dealing with stressful situations) were both positively associated with OCD. With regard to demographic factors, persons of older age and higher education levels were significantly less likely to have OCD. Copyright © 2012 Elsevier Ltd. All rights reserved.

Chromosomal rearrangements involving telomeric bands have been frequently detected in many malignancies and congenital diseases. To develop a useful tool to study chromosomal rearrangements within the telomeric band effectively and accurately, a whole set of telomeric band painting probes (TBP) has been generated by chromosome microdissection. The intensity and specificity of these TBPs have been tested by fluorescence in situ hybridization and all TBPs showed strong and specific signals to target regions. TBPs of 6q and 17p were successfully used to detect the loss of the terminal band of 6q in a hepatocellular carcinoma cell line and a complex translocation involving the 17p terminal band in a melanoma cell line. Meanwhile, the TBP of 21q was used to detect a de novo translocation, t(12;21), and the breakpoint at 21q was located at 21q22.2. Further application of these TBPs should greatly facilitate the cytogenetic analysis of complex chromosome rearrangements involving telomeric bands.

Clinical Impact and Cellular Mechanisms of Iron Overload-Associated Bone Loss

PubMed Central

Jeney, Viktória

2017-01-01

Diseases/conditions with diverse etiology, such as hemoglobinopathies, hereditary hemochromatosis and menopause, could lead to chronic iron accumulation. This condition is frequently associated with a bone phenotype; characterized by low bone mass, osteoporosis/osteopenia, altered microarchitecture and biomechanics, and increased incidence of fractures. Osteoporotic bone phenotype constitutes a major complication in patients with iron overload. The purpose of this review is to summarize what we have learnt about iron overload-associated bone loss from clinical studies and animal models. Bone is a metabolically active tissue that undergoes continuous remodeling with the involvement of osteoclasts that resorb mineralized bone, and osteoblasts that form new bone. Growing evidence suggests that both increased bone resorption and decreased bone formation are involved in the pathological bone-loss in iron overload conditions. We will discuss the cellular and molecular mechanisms that are involved in this detrimental process. Fuller understanding of this complex mechanism may lead to the development of improved therapeutics meant to interrupt the pathologic effects of excess iron on bone. PMID:28270766

Synthesis of Lipidated Proteins.

PubMed

Mejuch, Tom; Waldmann, Herbert

2016-08-17

Protein lipidation is one of the major post-translational modifications (PTM) of proteins. The attachment of the lipid moiety frequently determines the localization and the function of the lipoproteins. Lipidated proteins participate in many essential biological processes in eukaryotic cells, including vesicular trafficking, signal transduction, and regulation of the immune response. Malfunction of these cellular processes usually leads to various diseases such as cancer. Understanding the mechanism of cellular signaling and identifying the protein-protein and protein-lipid interactions in which the lipoproteins are involved is a crucial task. To achieve these goals, fully functional lipidated proteins are required. However, access to lipoproteins by means of standard expression is often rather limited. Therefore, semisynthetic methods, involving the synthesis of lipidated peptides and their subsequent chemoselective ligation to yield full-length lipoproteins, were developed. In this Review we summarize the commonly used methods for lipoprotein synthesis and the development of the corresponding chemoselective ligation techniques. Several key studies involving full-length semisynthetic lipidated Ras, Rheb, and LC3 proteins are presented.

Sporothricosis is endemic in numerous Latin American countries and the rest of the world. In Peru is concentrated in regions with warm and humid climate being little known in the rest of the country. To describe the epidemiological, clinical and laboratory characteristics of patients diagnosed of sporotrichosis in a tertiary-care level hospital in Lima, Peru from 1991 to 2014. This was a retrospective, case series. Ninety four patients were involved; most of them were male adults. This condition was acquired more frequently in Cajamarca, Apurímac, and Amazonas. Fixed and lymphocutaneous form were the most frequent forms of presentation in adults and were mostly distributed in upper limbs. Lesions located in head and neck were most frequent in children. Comorbidities were present in 15% of patients and were more frequent in those who presented disseminated cutaneous form. Seventy eight percent of cultures from skin lesions were positive within 7 days. The time to positivity of cultures was longer if the sample came from skin biopsies than skin scraping or skin aspiration. Most cases of sporotrichosis were acquired in areas of extreme poverty in Peru. The clinical, epidemiological and laboratory findings were similar to those reported elsewhere. The time to positivity of cultures varies based on the type of skin sample. This finding needs to be further evaluated in studies with an increased number of cases.

MELAS syndrome -myopathy, encephalopathy, lactic acidosis and stroke-like episodes- is a maternally-inherited mitochondrial cytopathy related to several mitochondrial DNA mutations, with the A3243G mutation in tRNA Leu gene being the most frequent of them. Apart from its typical symptomatology, patients usually exhibit a maternally-inherited history of neurosensory deafness and insulin-dependent type 2 diabetes mellitus (T2DM). Recent studies have shown that few patients carrying a A3243G mutation also suffer from renal dysfunction, usually in form of focal segmental glomerulosclerosis (FSGS). In this study we examine kidney involvement in 2 unrelated patients with a A3243G mutation by genetic testing. Both have a maternally-inherited neurosensory deafness and insulin-dependent T2DM. A renal biopsy was performed in both patients. One patient developed nephrotic proteinuria and renal insufficiency, with FSGS findings being observed in the kidney biopsy, whereas the other suffered from mild proteinuria and renal insufficiency, with non-specific glomerular changes. The presence of FSGS or other kidney involvement accompanied by hereditary neurosensory deafness and T2DM could be suggestive of a A3243G tRNA Leu mutation and should prompt a genetic testing and an evaluation of potential extrarenal involvement.

(1) To pilot 'we DECide' in terms of influence on advance care planning policy and practice in nursing home dementia care units. (2) To investigate barriers and facilitators for implementing 'we DECide'. This was a pre-test-post-test study in 18 nursing homes. Measurements included: compliance with best practice of advance care planning policy (ACP-audit); advance care planning practice (ACP criteria: degree to which advance care planning was discussed, and OPTION scale: degree of involvement of residents and families in conversations). Advance care planning policy was significantly more compliant with best practice after 'we DECide'; policy in the control group was not. Advance care planning was not discussed more frequently, nor were residents and families involved to a higher degree in conversations after 'we DECide'. Barriers to realizing advance care planning included staff's limited responsibilities; facilitators included support by management staff, and involvement of the whole organization. 'We DECide' had a positive influence on advance care planning policy. Daily practice, however, did not change. Future studies should pay more attention to long-term implementation strategies. Long-term implementation of advance care planning requires involvement of the whole organization and a continuing support system for health care professionals. Copyright © 2016 Elsevier Ireland Ltd.

Background Healthcare institutions are often faced with challenges and accreditation requirements for improving treatment quality, reducing waste, and avoiding diversion of drugs, particularly controlled substances. Many automated systems have replaced manual systems but may be fraught with challenges, especially when multiple users are involved. Objective To describe the characteristics of controlled substance discrepancies observed in a Level I trauma hospital for Medicare. Methods Discrepancy data were captured for each user involved in a transaction for a controlled substance at the Level I trauma hospital (in Ben Taub Hospital, Houston, TX), and the information was stored in a computerized database repository. Data for the 1-year study period (from January 1 through December 31, 2013) were collected for Medicare beneficiaries, using an Excel 2013 spreadsheet, and were analyzed according to basic discrepancy characteristics and descriptive statistics. Results During the 12-month study period, 114,000 controlled substance discrepancies were found for 100,000 Medicare patients at this Level I trauma hospital. Vending activities accounted for the majority (52.6%) of these discrepancies. Discrepancies were most likely to occur on Wednesdays, and the medications involved most frequently were combination drugs of hydrocodone and acetaminophen. Conclusion Approximately 1 (1.14) discrepancy involving a controlled substance occurred for each Medicare patient treated at the study facility. Healthcare institutions need to improve their efforts to ensure high-quality care and prevent diversion of drugs. PMID:27606038

Background: It is important to understand what motivates workers and the extent to which the organization and other contextual variables satisfy them. The aim of the study was to determine factors of dissatisfaction resulting from the organizational culture among the blacksmiths involved in the surgical instrument industry. Materials and Methods: Fifty male surgical blacksmiths each of the skilled and unskilled groups of the forging section were selected. Organizational Role Stress Scale was used to measure the individuals’ role stress and several forms of conflict within an organization. Also, the organizational culture and personal involvement in an organization was measured among the surgical blacksmiths. Results: The mean score for total role stress for Skilled was 71.7 and for unskilled was 77.2. The most frequent type of organizational culture was reported to be hierarchy, both by skilled and unskilled surgical blacksmiths, followed by market and clan culture. Conclusion: This study shows that the skilled surgical blacksmiths have lower level of stress and conflicts in comparison with unskilled surgical blacksmiths. Both skilled and unskilled surgical blacksmiths estimated their level of personal involvement as low and indicated insufficient involvement in work teams. The satisfaction of the employees with their status and role in the organizational culture was also poor for both skilled and unskilled surgical blacksmiths. PMID:23271868

Two groups of randomly chosen individuals who lived in two communities located different distances from the airport were studied. We monitored audiometry and brainstem auditory-evoked potentials to evaluate cochlear and retrocochlear functions in the individuals studied. The results of audiometry measurements indicated that hearing ability was reduced significantly in individuals who lived near the airport and who were exposed frequently to aircraft noise. Values of pure-tone average, high pure-tone average, and threshold at 4 kHz were all higher in individuals who lived near the airport, compared with those who lived farther away. With respect to brainstem auditory-evoked potentials, latencies between the two groups were not consistently different; however, the abnormality rate of such potentials was significantly higher in volunteers who lived near the airport, compared with less-exposed counterparts. In addition, a positive correlation was found between brainstem auditory-evoked potential latency and behavioral hearing threshold of high-frequency tone in exposed volunteers. We not only confirmed that damage to the peripheral cochlear organs occurred in individuals exposed frequently to aircraft noise, but we demonstrated involvement of the central auditory pathway.

OBJECTIVES: To describe the profile of patients treated in the trauma and orthopedics nursing of a trauma care referral public hospital of in the state of Bahia. METHODS: Cross-sectional study in which data were collected from medical records of patients in the period from July to December 2008. RESULTS: The profile of the patients involved was formed by subjects mostly male young subjects, victims of trauma from accidents, especially those with motorcycles or car runover. On the other hand,the most frequent traumas associated with urban violence were perforations by gunshot and stab wounds. The primary injury presented by these individuals was exposed fracture of the femur and the most common treatment was external fixation. The most frequent in-hospital complication was wound infection, which required another surgical approach. Most inpatients were discharged and only one death was reported during this period. CONCLUSION: The results of this study corroborate those from other institutions in the country, which may contribute to elaborate public policies for accidents and violence prevention.

Circulating tumour DNA (ctDNA) analysis facilitates studies of tumour heterogeneity. Here we employ CAPP-Seq ctDNA analysis to study resistance mechanisms in 43 non-small cell lung cancer (NSCLC) patients treated with the third-generation epidermal growth factor receptor (EGFR) inhibitor rociletinib. We observe multiple resistance mechanisms in 46% of patients after treatment with first-line inhibitors, indicating frequent intra-patient heterogeneity. Rociletinib resistance recurrently involves MET, EGFR, PIK3CA, ERRB2, KRAS and RB1. We describe a novel EGFR L798I mutation and find that EGFR C797S, which arises in ∼33% of patients after osimertinib treatment, occurs in <3% after rociletinib. Increased MET copy number is the most frequent rociletinib resistance mechanism in this cohort and patients with multiple pre-existing mechanisms (T790M and MET) experience inferior responses. Similarly, rociletinib-resistant xenografts develop MET amplification that can be overcome with the MET inhibitor crizotinib. These results underscore the importance of tumour heterogeneity in NSCLC and the utility of ctDNA-based resistance mechanism assessment. PMID:27283993

Alcohol use, liberal/conservative orientations, and ethnicity as predictors of sexual behaviors.

PubMed

Neff, J A; Burge, S K

1995-03-01

The present study examined relationships among ethnicity, gender, alcohol consumption, and sexual behaviors in a community survey sample of 1,392 adults. Predictors included liberal versus conservative orientations (sex role orientation, religiosity); traditional versus liberal attitudes regarding sexuality, typical alcohol consumption patterns, expectancies regarding alcohol's effect upon one's sexuality, and frequency of alcohol use before sex. Findings are consistent with other studies indicating more sex partners among males than females and among Blacks (particularly males) than Anglos. Blacks also reported less involvement in oral sex than Anglos and Mexican-Americans--although observed differences for oral sex were more characteristic of females and less characteristic of unmarried nondrinkers. Unmarried Mexican-American males reported somewhat, though not significantly, more partners than did Anglos. Unmarried Black males (particularly nondrinkers) also reported more frequent risky behaviors than did Anglos. Divorced Black female drinkers reported significantly less frequent risky behavior than their Anglo counterparts. Alcohol use-sexual relationships were independent of psychosocial background characteristics and situated drinking (drinking before sex) was more strongly related to sexual behavior dimensions than were general drinking patterns.

[Arterial involvements in hereditary dysplasia of the connective tissue].

Beylot, C; Doutre, M S; Beylot-Barry, M; Busquet, M

1994-03-01

Arterial involvement is an important feature of the diagnosis and, above all, prognosis of heritable disorders of connective tissue. In pseudoxanthoma elasticum, a progressive occlusive syndrome is associated with hemorrhage and especially with gastrointestinal bleeding. Aneurysms are uncommon. Hypertension occurs frequently. Cutaneous signs (yellowish pseudo xanthomatous papules of the large folds) the ocular changes (angioid streaks) and pathology showing numerous, thickened, fragmented, disorganized, calcified elastic fibers in the deep dermis and arterial walls, allow the diagnosis to be made. In the heterogeneous group of Ehlers-Danlos syndromes, type IV is characterized by sudden spontaneous rupture of the large arteries. Aneurysms and carotido-cavernous fistulae are rather frequent. Owing to friability of the arterial walls, arteriograms and other procedure requiring arterial puncture may prove hazardous and surgery difficult. Such patients have an acrogeric morphotype, and thin, fragile skin, but cutaneous hyperelasticity and joint hyperlaxity are usually minimal. Pathology evidences collagen hypoplasia in the skin and arterial walls. The severity of Marfan syndrome is due to aortic involvement. A fusiform aneurysm of the ascending aorta represents a vital risk of rupture. Aortic root dilatation is associated and responsible of severe aortic regurgitation. Aortic dissection is also a serious threat. Improved surgical techniques for repairing a dilated or dissected aortic root with simultaneous replacement of the aortic valve increases the life expectancy of such patients. Dolichomorphism is the characteristic skeletal abnormality, particularly with arachnodactyly and upward ectopia lentis, which is almost bilateral, is a very frequent feature of Marfan syndrome. The most typical histological finding is aortic cystic median necrosis. The basic defect in Marfan syndrome concerns the fibrillin, whose gene is located on chromosome 15. The three diseases detailed in this paper constitute the main areas of this subject, but arterial involvement may occur in other inheritable disorders of connective tissue (osteogenesis imperfecta, cutis laxa, Werner syndrome, Menkes syndrome, etc).

Biomarkers of multiorgan injury in neonatal encephalopathy.

Neonatal encephalopathy (NE) is a major contributor to neurodevelopmental deficits including cerebral palsy in term and near-term infants. The long-term neurodevelopmental outcome is difficult to predict with certainty in first few days of life. Multiorgan involvement is common but not part of the diagnostic criteria for NE. The most frequently involved organs are the heart, liver, kidneys and hematological system. Cerebral and organ involvement is associated with the release of organ specific biomarkers in cerebrospinal fluid, urine and blood. These biomarkers may have a role in the assessment of the severity of asphyxia and long-term outcome in neonates with NE.

2017-06-01

The aim of this study was to uncover patterns of pedestrian crashes. In the first stage, 34,178 pedestrian-involved crashes occurred in Iran during a four-year period were grouped into homogeneous clusters using a clustering analysis. Next, some in-cluster and inter-cluster crash patterns were analysed. The clustering analysis yielded six pedestrian crash groups. Car/van/pickup crashes on rural roads as well as heavy vehicle crashes were found to be less frequent but more likely to be fatal compared to other crash clusters. In addition, after controlling for crash frequency in each cluster, it was found that the fatality rate of each pedestrian age group as well as the fatal crash involvement rate of each driver age group varies across the six clusters. Results of present study has some policy implications including, promoting pedestrian safety training sessions for heavy vehicle drivers, imposing limitations over elderly heavy vehicle drivers, reinforcing penalties toward under 19 drivers and motorcyclists. In addition, road safety campaigns in rural areas may be promoted to inform people about the higher fatality rate of pedestrians on rural roads. The crash patterns uncovered in this study might also be useful for prioritizing future pedestrian safety research areas.

Cooperation, conflict, or disengagement? Coparenting styles and father involvement in fragile families.

PubMed

Waller, Maureen R

2012-09-01

This paper draws on information from the Fragile Families Study (N = 2,695) to examine how different coparenting styles emerge and are related to fathers' involvement with young children in a representative sample of unmarried parents. The results show that the quantity and quality of paternal involvement is significantly higher when unmarried parents establish a cooperative as opposed to a disengaged or conflicted coparenting style. Cooperative coparenting is less likely, however, when unmarried parents have separated after the birth or were never together as a couple, when fathers are unemployed or have other risk factors, when the child has a more difficult temperament, and when parents have fewer children together. This analysis also helps clarify previously equivocal findings concerning the relationship between coparenting conflict and paternal involvement. Regression results show that paternal involvement is not significantly different among parents with cooperative and mixed coparenting styles, indicating that when unmarried parents can work together and support each other's parenting efforts, even if they argue frequently while doing so, fathers remain more involved. At the same time, conflicted coparenting leads to a larger decrease in father involvement than disengaged coparenting. In the context of poorer-quality coparenting relationships, it was conflict that mattered for fathering, not just parents' inability to cooperate. Implications of these findings for parenting education programs are discussed. © FPI, Inc.

The incidence of invasive aspergillosis has increased worldwide. Information regarding the clinical characteristics of patients with extrapulmonary involvement is scarce. We aimed to describe the pathogenesis, characteristics and outcomes of patients with invasive aspergillosis and extrapulmonary disease. A retrospective study conducted in a university hospital in Barcelona, Spain (1995-2011). A total of 12 cases of invasive aspergillosis and extrapulmonary involvement were found. The most common clinical manifestations were invasive sinusitis, early postoperative prosthetic valve endocarditis, fungaemia, postoperative meningitis, multiple brain abscesses and lumbar spondylitis with epidural abscess. Sinusitis occurred frequently in patients without immunosuppression and had invasive brain involvement in one case. Endocarditis was associated with multiple septic metastases. Concomitant lung involvement was documented in 5 cases. The strains isolated were Aspergillus fumigatus (5), Aspergillus flavus (3), and Aspergillus niger (2). The species of Aspergillus was not established for 3 isolates. All patients were treated with antifungals and surgery was performed in 8 cases. Outcome was related with the source of infection; all patients with invasive sinusitis survived, while the remaining patients had a high mortality rate (88%). Invasive aspergillosis with extrapulmonary involvement is rare. The most common presentation is invasive sinusitis, which has a lower mortality. Other clinical forms with extrapulmonary involvement were associated with severe immunosuppression or previous surgery, and had a poor outcome. Copyright © 2011 Revista Iberoamericana de Micología.

Persons with a psychotic disorder commonly experience difficulties with what is considered to be metacognitive capacity. In this article we discuss several definitions of this concept, the measurement instruments involved and the clinical interventions that target this concept. To present a review of various frequently used definitions of metacognition and related concepts and to describe the measurement instruments involved and the treatment options available for improving the metacognitive capacity of persons with a psychotic disorder. We present an overview of several definitions of metacognition in psychotic disorders and we discuss frequently used measurement instruments and treatment options. The article focuses on recent developments in a model devised by Semerari et al. The measurement instrument involved (Metacognition Assessment Scale - A) is discussed in terms of it being an addition to existing methods. On the basis of the literature it appears that metacognition and related concepts are measurable constructs, although definitions and instruments vary considerably. The new conceptualisation of social information processing also leads to the development of a new form of psychotherapy that aims to help patients suffering from psychotic disorders to improve metacognitive capacity. There seems to be evidence that metacognitive abilities are a possible target for treatment, but further research is needed.
