    Ethylene glycol (EG) is a common cause of toxic ingestions. Gas chromatography (GC)-based laboratory assays are the gold standard for diagnosing EG intoxication. However, GC requires specialized instrumentation and technical expertise that limits feasibility for many clinical laboratories. The objective of this retrospective study was to determine the utility of incorporating a rapid EG assay for management of cases with suspected EG poisoning. The University of Iowa Hospitals and Clinics core clinical laboratory adapted a veterinary EG assay (Catachem, Inc.) for the Roche Diagnostics cobas 8000 c502 analyzer and incorporated this assay in an osmolal gap-based algorithm for potential toxic alcohol/glycol ingestions. The main limitation is that high concentrations of propylene glycol (PG), while readily identifiable by reaction rate kinetics, can interfere with EG measurement. The clinical laboratory had the ability to perform GC for EG and PG, if needed. A total of 222 rapid EG and 24 EG/PG GC analyses were documented in 106 patient encounters. Of ten confirmed EG ingestions, eight cases were managed entirely with the rapid EG assay. PG interference was evident in 25 samples, leading to 8 GC analyses to rule out the presence of EG. Chart review of cases with negative rapid EG assay results showed no evidence of false negatives. The results of this study highlight the use of incorporating a rapid EG assay for the diagnosis and management of suspected EG toxicity by decreasing the reliance on GC. Future improvements would involve rapid EG assays that completely avoid interference by PG. PMID:26553280

  3. Adolescent death: a 15-year retrospective review.

    Batalis, Nick I; Collins, Kim A

    2005-11-01

    Adolescents comprise an eclectic mix of people vitally important to society yet long-term comprehensive studies on the circumstances of their deaths are lacking in the pediatric forensic literature. The authors reviewed all forensic cases referred to the Medical University of South Carolina Forensic Pathology section over the fifteen years between January 1989 and December 2003. In accordance with the World Health Organization (WHO) definition of adolescents, only decedents 10-19 years of age were included. The authors examined the cause and manner of death, age, gender, and race of the victims in all cases. The toxicology results, perpetrator, death scenario and location, and victim traits were analyzed when available. For all adolescents, the most common manner of death was accident followed by homicide, suicide, natural, and undetermined. Within the adolescent population two distinct groups, 10-14 years old and 15-19 years old, were identified. Though both groups were similar in that they experienced a high number of accidental deaths, decedents of older age group suffered a higher percentage of violent deaths while decedents of the younger group were more likely to die of natural causes. Many of the accidental deaths in this review were preventable, including deaths due to motor vehicle collisions and drowning. In deaths due to homicide, the perpetrator was often known to the victim, whether as an acquaintance or family member. Toxicology testing was often positive in decedents of the older age group, while only rarely positive in decedents of the younger age group. With a solid understanding of the circumstances, it may be possible to predict, and hopefully prevent, future cases of adolescent death. The authors present their findings in this 15-year retrospective study to better aid forensic pathologists, death investigators, law enforcement, and epidemiologists. PMID:16382843

    Children born at the end of the academic year have lower educational attainment, on average, than those born at the start of the academic year. Previous research has shown that the difference is most pronounced early in pupils’ school lives, but remains evident and statistically significant in high-stakes exams taken at the end of compulsory schooling. Those born later in the academic year are also significantly less likely to participate in post-compulsory education than those born at the st...

  14. Planned and unplanned complex suicides: a 5-year retrospective study.

    Racette, Stéphanie; Sauvageau, Anny

    2007-03-01

    The notion of planned and unplanned complex suicides first appeared in 1974 by Marcinkowski and, since then, no systematic study of complex suicides has been published in the English forensic literature. Here, the authors present a 5-year retrospective study of complex suicides. Nineteen complex suicides were reviewed: five unplanned and 14 planned, including the first case of an unplanned complex suicide in a woman. All cases were analyzed in terms of gender, age, methods of suicide, the presence of a suicide note, and past suicide attempts, and statistically compared with a 50-case sample of simple suicides. A further comparison was established with compiled data from the literature. Similarities were revealed regarding incidence of complex suicides, male gender predominance, and types of methods used. In contrast, results showed a higher average age for planned complex suicide victims. Finally, the authors discuss the application of the complex suicide definition. PMID:17316249

Materials and Methods: This is a retrospective study of 28 women of gestational trophoblastic neoplasia evaluated over a period of 6 years from January 2004 to December 2009. Patients were evaluated on the basis of their age, number of deliveries, history of abortion or molar pregnancy, and the treatment received. All patients were scored on the basis of WHO scoring system. Patients with low risk (score /=7 received multiple agent chemotherapy with EMACO regimen. After completion of chemotherapy patients were followed for a minimum of 2 years. The response to treatment was evaluated during follow-up by clinical examination, beta hCG levels and imaging as and when required. Results: Out of 28 women only 27 could be evaluated, because 1 patient was lost to follow-up. Out of 27 patients, 18 patients (66.67% achieved complete remission with the first-line chemotherapy and additional 25.92% (7/27 achieved complete remission with second line chemotherapy resulting in complete remission of 92.5% (25/27. Conclusion: Gestational trophoblastic neoplasia is curable if patient is properly evaluated and scored. It shows good response to chemotherapy.

    2009-12-01

    This retrospective longitudinal study aims to describe reported Taekwondo injuries and to examine associations between competitor experience level, age and gender, and the type, location, and mechanism of injury sustained. Additionally, we examined whether recent rule changes concerning increased point value of head shots in adult Taekwondo competition had affected injury incidence.This study was a summation of 9 years of data of competition injury reports, which included 904 injury reports spanning 58 individual competitions. The data was collected on standardized injury reports at time of injury during competition. Care was provided to the athletes, but the type of care provided was not included in the study. Participants included athletes injured during competition who sought care by the health care team, and for whom an injury report was filled out. The data analysis was performed at the Canadian Memorial Chiropractic College.The three most common locations of presenting injury were the head (19%), foot (16%), and thigh (9%). The most common mechanism of presenting injury was found to be a defensive kick (44%), followed by an offensive kick (35%). The most commonly diagnosed injuries were contusions (36%), sprains (19%), and strains (15%). Coloured belts had a higher incidence of contusions, while black belts sustained more joint irritation injuries. Black belts were more likely to suffer multiple injuries. Colored belts suffered more injuries while receiving a kick, while black belts had a larger influence of past history of injury. We found no significant difference in location or type of injury when comparing pre versus post rule change. The most common locations of injury are head, foot, and thigh respectively, and are areas for concern when considering preventative measures. Colour belt competitors are more likely to sustain contusions, which the authors believe is due to more aggressive tactics and lack of control. Those more likely to be injured tend to

  1. Verb-Noun Collocation Proficiency and Academic Years

    Fatemeh Ebrahimi-Bazzaz

    2014-01-01

    Full Text Available Generally vocabulary and collocations in particular have significant roles in language proficiency. A collocation includes two words that are frequently joined concurrently in the memory of native speakers. There have been many linguistic studies trying to define, to describe, and to categorise English collocations. It contains grammatical collocations and lexical collocations which include nouns, adjectives, verbs, and adverb. In the context of a foreign language environment such as Iran, collocational proficiency can be useful because it helps the students improve their language proficiency.This paper investigates the possible relationship between verb-noun collocation proficiency among students from one academic year to the next. To reach this goal, a test of verb-noun collocations was administered to Iranian learners. The participants in the study were 212 Iranian students in an Iranian university. They were selected from the second term of freshman, sophomore, junior, and senior years. The students’ age ranged from 18 to 35.The results of ANOVA showed there was variability in the verb-noun collocations proficiency within each academic year and between the four academic years. The results of a post hoc multiple comparison tests demonstrated that the means are significantly different between the first year and the third and fourth years, and between the third and the fourth academic year; however, students require at least two years to show significant development in verb-noun collocation proficiency.  These findings provided a vital implication that lexical collocations are learnt and developed through four academic years of university, but requires at least two years showing significant development in the language proficiency.Keywords: Language proficiency, Collocation, Communicative Competence, academic year, Iranian EFL learners

    2015-01-01

    Background. Acute generalized exanthematous pustulosis (AGEP) is an acute pustular eruption characterized by widespread nonfollicular sterile pustules. The aim of this study is to characterize the etiology, clinical features, laboratory findings, management, and outcome of patients with AGEP in Asians. Patient/Methods. A retrospective analysis was performed on patient who presented with AGEP between August 2008 and November 2012 in a tertiary center in Thailand. Results. Nineteen patients with AGEP were included. AGEP was generally distributed in seventeen patients (89.5%) and localized in two (10.5%). Fever and neutrophilia occurred in 52.6% and 68.4%, respectively. Hepatitis was found up to 26.3%. The most common etiology was drugs (94.7%), comprising of antibiotics (73.6%), proton pump inhibitors (10.5%), nonsteroidal anti-inflammatory drugs (5.3%), and herbal medicine (5.3%). Beta-lactams were the most common causal drug, particularly carbapenems and cephalosporins. This is the first report of Andrographis paniculata as an offending agent for AGEP. We found no differences between various treatment regimens (topical corticosteroid, systemic corticosteroid, and supportive treatment) regarding the time from drug cessation to pustules resolution (P = 0.171). Conclusions. We have highlighted the presentation of AGEP among Asians. We found high association with systemic drugs. Carbapenems were one of the leading culprit drugs. Finally, a localized variant was observed. PMID:26783390

    Full Text Available Since bat rabies surveillance was first implemented in France in 1989, 48 autochthonous rabies cases without human contamination have been reported using routine diagnosis methods. In this retrospective study, data on bats submitted for rabies testing were analysed in order to better understand the epidemiology of EBLV-1 in bats in France and to investigate some epidemiological trends. Of the 3176 bats submitted for rabies diagnosis from 1989 to 2013, 1.96% (48/2447 analysed were diagnosed positive. Among the twelve recognised virus species within the Lyssavirus genus, two species were isolated in France. 47 positive bats were morphologically identified as Eptesicus serotinus and were shown to be infected by both the EBLV-1a and the EBLV-1b lineages. Isolation of BBLV in Myotis nattereri was reported once in the north-east of France in 2012. The phylogenetic characterisation of all 47 French EBLV-1 isolates sampled between 1989 and 2013 and the French BBLV sample against 21 referenced partial nucleoprotein sequences confirmed the low genetic diversity of EBLV-1 despite its extensive geographical range. Statistical analysis performed on the serotine bat data collected from 1989 to 2013 showed seasonal variation of rabies occurrence with a significantly higher proportion of positive samples detected during the autumn compared to the spring and the summer period (34% of positive bats detected in autumn, 15% in summer, 13% in spring and 12% in winter. In this study, we have provided the details of the geographical distribution of EBLV-1a in the south-west of France and the north-south division of EBLV-1b with its subdivisions into three phylogenetic groups: group B1 in the north-west, group B2 in the centre and group B3 in the north-east of France.

    2015-08-01

    Full Text Available SUMMARY: Mucocele is a common cystic lesion of the minor salivary glands with or without epithelium lining. It derives following trauma of the gland itself or its excretory duct resulting to saliva accumulation within the soft tissues. The most common site of occurrence is the lower lip. Aim: In this retrospective study, mucoceles in infants (0-3 years old were evaluated. Material and methods: Data were retrieved from the medical records of patients up to 3 years old, treated under general anesthesia the period 2000-2014 at the pediatric Hospital «P. and A. Kyriakou». Parameters evaluated included gender, age, site of occurrence, clinical appearance of the lesion, etiology for the development, type of treatment, histological findings and recurrences. Results: 17 patients were included in the study, 8 boys (47% and 9 girls (53%. Age ranged from 5 months to 3 years (mean: 20 months. All lesions were in the lower lip and most common aetiology was trauma. They presented as small sized asymptomatic swellings, soft in palpation, elastic or flaccid, covered with normal or irritated oral mucosa. Treatment was surgical in all cases under general anesthesia, with removal of both the cystic lesion and the minor salivary gland. No recurrence occurred. Conclusion: Mucoceles can be found in very young ages even before the eruption of deciduous teeth. These lesions are treated surgically and because of the very young age general anesthesia is preferable.

    2015-03-01

    Full Text Available Introduction: Self-care activities, including exercise, may be neglected by medical students in response to increasing academic demands. Low levels of exercise among medical students may have ripple effects on patient care and counseling. This study investigates the reciprocal role of recreation use and academic performance among first-year medical students. Methods: We combined retrospective administrative data from four cohorts of first-year medical students at the University of Illinois at Urbana-Champaign from 2006 to 2010 (n=408. We estimated regression models to clarify the role of changes in recreation use before examinations on changes in academic performance, and vice versa. Results: The use of recreation facilities by first-year medical students was highly skewed. We found that changes in recreation use before an exam were positively associated with changes in exam performance, and vice versa. Students who make large decreases in their recreation use are likely to decrease their exam scores, rather than increase them. Discussion: Students who make decreases in their recreation, on average, are likely to decrease their exam scores. These findings suggest that medical students may be able to boost their achievement through wellness interventions, even if they are struggling with exams. We find no evidence that decreasing wellness activities will help improve exam performance.

  11. Flash smelting and converting furnaces: A 50 year retrospect

    Kojo, Ilkka V.; Jokilaakso, Ari; Hanniala, Pekka

    2000-02-01

    1999 marked the 50th anniversary of the Outokumpu flash-smelting process. Originating during the post-World War II energy crisis, flash smelting is a high-intensity process developed to attain ever-increasing throughputs and intensities. Many innovations and continuous development ensued during the next 50 years before today’s state-of-the-art copper-making process chain and environmental benchmarking technology (e.g., Outokumpu flash smelting, Kennecott-Outokumpu flash converting, and flash technology) became possible. This article reviews how Outokumpu flash furnace design, especially cooling for higher heat loads, has improved over the years.

    Orbital metastases from breast cancer (BC) are rare, but often debilitating. BC accounts for nearly half of metastases to the orbit. Orbital metastases may be discovered years after the initial diagnosis of BC, and are rare at initial presentation. A search of the institutional data base at an academic cancer center identified BC patients who developed or presented with orbital metastases from 2000 to 2013. Baseline characteristics, treatment modalities, survival and treatment responses were collected from the electronic medical record. There were 20 patients identified with orbital metastases (0.7% of all BC cases). The median age at diagnosis of BC was 49 years; 80% had estrogen positive disease. The interval between the initial diagnosis of BC and the presentation of orbital metastases was 8.5 years (0-19 years). Orbital disease was the initial presentation of BC in two cases. Three patients developed bilateral orbital metastases and seven had accompanying brain metastases. The most common presentation was decreased vision (55%), followed by diplopia (25%). The median survival after orbital metastases was 24 months. Thirteen patients (65%) received local radiation therapy. Of those radiated, 90% reported improvement of orbital symptoms. Other treatments included intraocular bevacizumab, surgery, and systemic therapy. Orbital metastases tend to occur in estrogen receptor positive disease and are often found years after BC onset. Orbital metastases may be associated with the development of brain metastases. Radiotherapy is the preferred local therapy and had high symptom control in this cohort. Oncologists should be aware of the signs of orbital metastases and the treatment options. PMID:27143519

    Full Text Available Background: Gestational trophoblastic disease (GTD defines a heterogenenous group ofinterrelated lesions that arise from the trophoblastic epithelium of the placenta. There are severalhistologically distinct types of GTD: hydatiform mole (complete or partial, persistant/invasivegestational trophoblastic neoplasia (GTN, choriocarcinoma and placenta site trophoblastictumors. The aim of this study was to determine the frequency and risk factors of GTD amongwomen admitted to Imam Khomeini Hospital in Ahvaz, Iran.Materials and Methods: This was a cross-sectional study conducted at Imam KhomeiniHospital in Ahvaz, Iran. All hospital records related to GTD (132 from 1996 until 2006 werereviewed. Demographic and histo-pathologic characteristics were extracted. Chi-square andFisher-exact tests were used to analyze all variables. P ≤ 0.05 was considered statisticallysignificant. SPSS, version 11 was used for statistical analysis.Results: The mean age of patients was 27.6 years. Most patients who presented with GTDwere of ages 18-35 years (71.3%. There was no relationship between age and hydatiformmole during the reproductive years. There were 28 (18.9% patients over the age 40, of which18 (15.90% of these had a complete hydatiform mole. Within this group, 9 (6.8% changedto a persistent mole. There was a significant relationship between age over 40 and completemole (p<0.02. The percentage of patients with blood groups A and O was the same (37.9%.There was a significant relationship between blood groups (O+ and A+ and complete mole(p<0.05.Conclusion: The most common age range for hydatiform mole was 18-35 years. Women overthe age of 40 had a more complete hydatiform mole, which is similar to the other countries.Age and blood group are two risk factors for hydatiform mole.

    In a paper published in The Review of Economics and Statistics some 20 years ago, we sought to assess the disparate residential location choices of black and white households in the Washington, D.C. metropolitan area (Gabriel and Rosenthal [1989]). The paper showed that simulated closure of large socio-economic gaps between blacks and whites did little to diminishprevailing high levels of residential segregation or otherwise enhance moves by black households to areas of educational, employmen...

  16. The anomaly of Marquesan ceramics : a fifty year retrospective

    Fifty years ago pioneering archaeologist Robert Suggs reported a small number of pottery sherds from the Marquesas Islands. The first such finds in East Polynesia, at the time they were considered indicative of both a Marquesan homeland and local ceramic manufacture. In the intervening years, additional sherds have been recovered from three other Marquesan localities resulting in a total of 14 specimens. Prior petrographic studies demonstrate unambiguously that some derive from Fiji. Others have been interpreted historically as representative of an indigenous Marquesan ceramic industry. Here we bring together key petrographic analyses from Polynesia, recent chronological assessments of the Marquesan sequence, and insights from new field research to reassess the origins and chronology of Marquesan pottery. We suggest that there is little support for an indigenous Marquesan ceramic industry, and most likely all of the specimens are imports. With respect to the timing of ceramic arrivals, three hypotheses are explored: 1) with founding settlers, 2) as a component of long-distance exchange networks operating between the 12th to 16th centuries AD, or 3) as late prehistoric or historic imports. The preponderance of evidence points to the second alternative, although the other two cannot be completely discounted for the assemblage as a whole. (author). 63 refs., 5 figs., 3 tabs.

    2005-09-01

    In the five years since the NASA Glenn Research Center Acoustical Testing Laboratory (ATL) opened its doors in September, 2000, it has developed a comprehensive array of services and products that support hearing conservation goals within NASA and industry. The ATL provides acoustic emission testing and noise control engineering services for a variety of specialized customers, particularly developers of equipment and science experiments manifested for NASA's manned space missions. The ATL aggressively supports the vision of a low-noise on-orbit environment, which facilitates mission success as well as crew health, safety, and comfort. In concert with these goals, the ATL also produces and distributes free educational resources and low-noise advocacy tools for hearing conservation education and awareness. Among these are two compact discs of auditory demonstrations (of phenomena in acoustics, hearing conservation, and communication), and presentations, software packages, and other educational materials for use by engineers, audiologists, and other hearing conservation stakeholders. This presentation will highlight ATL's construction, history, technical capabilities, and current projects and will feature demonstrations of some of the unique educational resource materials that are distributed by the ATL.

    Full Text Available Objective: The aim of this study was to review cases of odontogenic tumors diagnosed in two pathology centers in Tehran, Iran, during a 10-year period. Study Design: Patients′ records were seen at two teaching pathology Centre′s of Shahid Beheshti University between the months of March 2000 to 2010 with histologic diagnosis of any type of odontogenic tumors. The records were analyzed for frequency, age, sex, site, as well as clinical, radiographic and histopathologic findings. Results: Of 30706 biopsies, 4767 (15.5% cases were diagnosed as oral and maxillofacial lesions. Among these, 720 cases were tumoral with 188 (26.1% cases of odontogenic tumors. Tumors with odontogenic epithelium origin formed 70.2% of total numbers of odontogenic tumors. Mixed odontogenic tumors and tumors of odontogenic ectomesenchyme comprised 12.2% and 17.5% of the cases respectively. Ameloblastoma, with a frequency of 62.2% was the most common tumor in this review which was followed by odontoma and odontogenic myxoma. Conclusion: Although there are few studies on odontogenic tumors in literature, the comparison of our results with existing data shows significant differences in the distribution of tumors and age of patients, which may be due to ethnic features and geographic distribution of patients. Future studies on other ethnic groups are essential for further clarification of the findings in this research.

    Background Cutaneous hyperpigmentation is an often overlooked clinical sign in megaloblastic anemia (MA) which has been sporadically reported in the literature. Methods We describe the bone marrow (BM) changes and clinicolaboratory characteristics of 25 of 198 adult cases (>16 years) with cutaneous hyperpigmentation who underwent BM evaluation for cytopenia (s). Results Twenty-one of 25 cases (84%) had MA, while MA without hyperpigmentation occurred only in 12 of remainder 173 cases (P0.05). In six cases where follow-up data were available, there was a significant reversal of hyperpigmentation at 12 weeks following parenteral cobalamin therapy. In all five cases with pyrexia, fever subsided after 24 to 72 hours following administration of parenteral cobalamin therapy. Conclusion Cutaneous hyperpigmentation and cytopenia (s) are strongly associated with megaloblastic anemia. Knuckle pad hyperpigmentation is much more frequent than diffuse pigmentation of the palms and/or soles in such patents. A nonsignificant trend towards a greater degree of MA was found in cases with pigmentation of the knuckles. PMID:27158434

  8. The Belgian nuclear education network, 5th academic year

    Full text: In a country where a substantial part of the electricity generation will remain of nuclear origin for a number of years, there is a need for well educated and well trained engineers in this area. Public authorities, regulators and industry brought their support to this initiative. In 2001, the Belgian Nuclear Research Centre SCK CEN and five Belgian universities signed a consortium agreement to set up an education programme in nuclear engineering. This academic year, a sixth university, ULB, joined the programme. The universities involved are now: KUL (Leuven), UG (Ghent), VUB (Brussels), UCL (Louvain-la-Neuve), ULg (Liege) and ULB (Brussels). These seven partners have engaged themselves anew to provide students and young-professionals with a high-standard nuclear engineering programme. The BNEN academic programme is a one-year (60 ECTS) Master-after-Master programme open for holders of a Master degree in engineering. The programme consists of ten courses to be followed mandatory (41 ECTS), the opportunity to select a number of advanced courses at will (up to 4 ECTS worth) and a Master thesis (15 ECTS). The subjects of the courses range form nuclear physics, nuclear reactor theory, nuclear thermo hydraulics to reactor plant operation and control, radiation protection and safeguards and nuclear materials. It also includes courses on nuclear energy and the nuclear fuel cycle. All courses are given in a modular fashion, i.e. the students get a course in the duration of one up to three weeks of continuous lectures and lab sessions. Attention is indeed paid to the fact that most courses are not only theoretical ones, but many of them have exercise sessions and laboratory sessions associated with them. These sessions are organised and thought by the scientific staff at SCK CEN. The number of students enrolling for the BNEN has seen a serious growth since the start of the initiative. The programme does not serve only 'full-time' students, i.e. people having

    2012-11-01

    Full Text Available Abstract Background This was a retrospective cohort study undertaken to assess the rate and pattern of dental caries development in 6-year-old school children followed-up for a period of 5 years, and to identify baseline risk factors that were associated with 5 years caries experience in Malaysian children. Methods This 5-years retrospective cohort study comprised primary school children initially aged 6 years in 2004. Caries experience of each child was recorded annually using World Health Organization criteria. The rates of dental caries were recorded in prevalence and incidence density of carious lesions from baseline to final examination. Risk assessment was done to assess relative risk for caries after 5 years in children with baseline caries status. Simple and multiple logistic regression analysis were performed to identify significant independent risk factors for caries. Results The sample consisted of 1830 school children. All components of DMFT showed significant differences between baseline and final examination. Filled teeth (FT component of the DMFT showed the greatest increases. Results revealed the initial baseline caries level in permanent dentition was a strong predictor for future caries after 5 years (RR=3.78, 95% CI=3.48-4.10, P0.001. Logistic regression analysis showed significant association between caries occurrence and residence (urban/rural (OR=1.80, Pp observed from baseline and after 5 years was 5.80 persons/100 person-year of observation. The rate of new caries-affected tooth (IDt in the period from baseline and after 5-years was 0.76 teeth/100 teeth-year of observation. Conclusion The majority of 12-year-old school children (70% were caries-free and most of the caries were concentrated in only a small proportion (30% of them. We found that the presence of caries in permanent teeth at the age of 6 years was a strong predictor of future caries development in this population. The strong evidence of early permanent teeth

    Rugby is a popular sport in South Africa, and has been played by young boys from as early as seven years old (South African Rugby Union [SARU], 2011). Despite various physical health benefits, it carries a high risk for injury, especially head injury, and consequently has a high incidence of concussion (Alexander, 2009; Laubscher, 2006; Shuttleworth-Edwards, Smith & Radloff, 2008). It is common for 12 to 13 per cent of adolescent rugby players to report mild traumatic brain injury or concussi...

  19. The fate of titanium miniplates and screws used in maxillofacial surgery: a 10 year retrospective study.

    O'Connell, J

    2012-01-31

    The objective of this 10 year, retrospective study is to evaluate the indications for the removal of titanium miniplates following osteosynthesis in maxillofacial trauma and orthognathic surgery. All patients who had miniplates placed in a Regional Oral and Maxillofacial Department between January 1998 and October 2007 were included. The following variables were recorded: patient gender and age, number of plates inserted, indications for plate placement, location of plates, number and location of plates removed, indications for plate removal, time between insertion and removal, medical co-morbidities, and the follow-up period. During the 10 years of the study, 1247 titanium miniplates were placed in 535 patients. A total of 32 (3%) plates were removed from 30 patients. Superficial infection accounted for 41% of all plates removed. All complications were minor and most plates were removed within the first year of insertion. A low removal rate of 3% suggests that the routine removal of asymptomatic titanium miniplates is not indicated.

  20. Sudden cardiac death while playing Australian Rules football: a retrospective 14 year review.

    Parsons, Sarah; Lynch, Matthew

    2016-06-01

    Australian Rules football is a sport which evolved from Gaelic football and which is played by a large number of predominantly male participants in a number of countries. The highest participation rates are in the southern states of Australia. A retrospective review over a period of 14 years identified 14 cases of sudden cardiac death that occurred in individuals while playing the sport. All were male and ranged in age from 13 to 36 years with a mean and median age of 23 years. A spectrum of cardiac causes was identified including coronary artery atherosclerosis, myocarditis, anomalous coronary artery anatomy, arrhythmogenic right ventricular cardiomyopathy, and healed Kawasaki disease. In 5 cases the heart was morphologically normal raising the possibility of a channelopathy. No traumatic deaths were identified. Some of the individuals had experienced symptoms prior to the fatal episode and the role of pre participation screening in reducing mortality is discussed. PMID:26972904

    Lazaratou, Helen; Paparrigopoulos, Thomas; Galanos, Gerassimos; Psarros, Constantinos; Dikeos, Dimitris; Soldatos, Constantin

    2008-04-01

    Aim of the present study was to retrospectively assess the impact of a catastrophic earthquake in a sample of 121 survivors, 50 years after the event. Mean age +/- SD of the responders was 72.2 +/- 6.1 years. The majority of the victims (78%) acknowledged a strong overall impact of the earthquake on their lives, and almost all of them had intense recollection of the event at its anniversary. The most frequent symptom during the 6 months after the earthquake was persistent remembering or "reliving" of the event; women had considerably more often recurrent dreams of the earthquake and distress than did men.

    2016-02-25

    Objective. To determine the ability of University of Maryland Eastern Shore School of Pharmacy's admissions criteria to predict students' academic performance in a 3-year pharmacy program and to analyze transferability to African-American students. Methods. Statistical analyses were conducted on retrospective data for 174 students. Didactic and experiential scores were used as measures of academic performance. Results. Pharmacy College Admission Test (PCAT), grade point average (GPA), interview, and observational scores combined with previous pharmacy experience and biochemistry coursework predicted the students' academic performance except second-year (P2) experiential performance. For African-American students, didactic performance positively correlated with PCAT writing subtests, while the experiential performance positively correlated with previous pharmacy experience and observational score. For nonAfrican-American students, didactic performance positively correlated with PCAT multiple-choice subtests, and experiential performance with interview score. The prerequisite GPA positively correlated with both of the student subgroups' didactic performance. Conclusion. Both PCAT and GPA were predictors of didactic performance, especially in nonAfrican-Americans. Pharmacy experience and observational scores were predictors of experiential performance, especially in African-Americans. PMID:26941432

    Full Text Available Abstract Background Medical school attrition is important - securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001–2011 and to study the personal effects of dropout on individual students. Methods The study included quantitative analysis of completed cohorts and qualitative analysis of ten-year data. Data were collected from individual student files, examination and admission records, exit interviews and staff interviews. Statistical analysis was carried out on five successive completed cohorts. Qualitative data from student files was transcribed and independently analysed by three authors. Data was coded and categorized and key themes were identified. Results Overall attrition rate was 5.7% (45/779 in 6 completed cohorts when students who transferred to other medical courses were excluded. Students from Kuwait and United Arab Emirates had the highest dropout rate (RR = 5.70, 95% Confidence Intervals 2.65 to 12.27;p  Absenteeism was documented in 30% of students, academic difficulty in 55.7%, social isolation in 20%, and psychological morbidity in 40% (higher than other studies. Qualitative analysis revealed recurrent themes of isolation, failure, and despair. Student Welfare services were only accessed by one-third of dropout students. Conclusions While dropout is often multifactorial, certain red flag signals may alert us to risk of dropout including non-EU origin, academic struggling, absenteeism, social isolation, depression and leave of absence. Psychological morbidity amongst dropout students is high and Student Welfare services should be actively promoted. Absenteeism should prompt early intervention. Behind every dropout statistic lies a personal story. All

    Kugelberg, C F

    1990-12-01

    The long-term effects on periodontal tissues of impacted lower 3rd molar surgery have been investigated in a retrospective study comprising 51 cases. The postoperative examinations took place 2 and 4 years after the surgical treatment and included both clinical and radiographic variables. Assessments were made regarding the oral hygiene status, gingival condition and periodontal tissue breakdown in terms of increased probing depths and intrabony defects. Comparing the results of the two examinations, no significant changes of the incidence of plaque and gingivitis were seen on the distal surface of the 2nd molar, nor any significant change concerning the probing depth. The proximal bone level distal to the second molar was recorded by radiographic examination with a cut-off periodontal probe as indicator. Two years postoperatively, 16.7% of the cases aged less than or equal to 25 years showed intrabony defects exceeding 4 mm, compared with 40.7% in the age group greater than or equal to 26 years. At the 4-year re-examination, the corresponding figures were 4.2% and 44.4%, respectively. The improvement concerning the alveolar bone level was mainly seen in individuals under 25 years. Some factors affecting the periodontal healing after impacted lower 3rd molar surgery are discussed. PMID:2128310

    Retrospectively analyze the reconstruction methods and surgical outcomes of patients with middle and lower face soft tissue defects treated at our hospital over the past 10 years. 200 patients with middle and lower face soft tissue defects were surgically reconstructed at our hospital. Medical charts were retrospectively reviewed and analyzed to abstract the pertinent information. The lesion was mainly at the eyelid, lips, chin and nasal-cheek region. There were 41 (63.08 %) men and 24 (36.92 %) women. In our study, male to female ratio = 1.7:1. We used direct closure for night patients, local flap for 141 patients, free flap for 38 patients, combined flap for 12 patients involving extensive mid face and lower face defects. Most patients had their tumor resected and reconstructed in single stage procedure mostly with local advancement flap, and no flap failure was presented post-operatively. Middle and lower face soft tissue defects can be successfully treated with local flap in a single stage approach and step-by-step approach. PMID:27508131

    2010-03-01

    The purpose of this pilot study was: (1) to determine how students surviving brain tumors (BTs) perceive their teachers' responses to them, their own academic performance, and their interactions with peers at school using a new measure; and (2) to describe students' retrospective perceptions of schooling while undergoing treatment. Using a sample of 22 students treated for a BT (ages 9-18) and 22 comparison (ages 8-19), no significant BT-control group differences regarding perceptions of teacher response, academic performance, and interactions with peers at school were found. Generally, students with BTs reported positive school experiences during treatment including favorable perceptions of their teachers' effectiveness, enjoyment of schoolwork, and the quality of their schooling. Additionally, they felt that completing schoolwork during treatment was important. The results of this study may provide insight into the perceived psychosocial adjustment and academic performance of students with BTs during and after treatment. PMID:20147566

  9. How to Interpret Thyroid Biopsy Results: A Three-Year Retrospective Interventional Radiology Experience

    Results of thyroid biopsy determine whether thyroid nodule resection is appropriate and the extent of thyroid surgery. At our institution we use 20/22-gauge core biopsy (CBx) in conjunction with fine-needle aspiration (FNA) to decrease the number of passes and improve adequacy. Occasionally, both ultrasound (US)-guided FNA and CBx yield unsatisfactory specimens. To justify clinical recommendations for these unsatisfactory thyroid biopsies, we compare rates of malignancy at surgical resection for unsatisfactory biopsy results against definitive biopsy results. We retrospectively reviewed a database of 1979 patients who had a total of 2677 FNA and 663 CBx performed by experienced interventional radiologists under US guidance from 2003 to 2006 at a tertiary-care academic center. In 451 patients who had surgery following biopsy, Fisher's exact test was used to compare surgical malignancy rates between unsatisfactory and malignant biopsy cohorts as well as between unsatisfactory and benign biopsy cohorts. We defined statistical significance at P = 0.05. We reported an overall unsatisfactory thyroid biopsy rate of 3.7% (100/2677). A statistically significant higher rate of surgically proven malignancies was found in malignant biopsy patients compared to unsatisfactory biopsy patients (P = 0.0001). The incidence of surgically proven malignancy in unsatisfactory biopsy patients was not significantly different from that in benign biopsy patients (P = 0.8625). In conclusion, an extremely low incidence of malignancy was associated with both benign and unsatisfactory thyroid biopsy results. The difference in incidence between these two groups was not statistically significant. Therefore, patients with unsatisfactory biopsy specimens can be reassured and counseled accordingly.

    Vella, Anna Maria; Savona Ventura, Charles; Wolff, Kim

    2016-05-01

    In this ten-year retrospective study we were able to show that Maltese substance-misusing mothers (SMMs) have significantly different socio-biological characteristics from mothers in the general population which seem to impact on neonatal outcomes. Significant differences from the general population were noted in the SMM's age, age at first pregnancy, marital status, educational background, number of cigarettes smoked, number of offspring and weight gained in pregnancy. SMMs booked their pregnancy in hospital later than the general population. On the other hand their infants had a lower mean birth weight and head circumference, had lower Apgar scores, were of lesser gestational age and premature. They were less breast-fed and stayed longer in hospital after their birth. PMID:26467264

    Full Text Available Background The aim of this study was to assess the prevalence of hospitalisation for otitis media across the different risk indicators for Western Australian children (less than 15 years old over a 10-year period. Method This retrospective population-based study usedthe de-identified detailed data of children under the age of 15 years, hospitalised for otitis media(OM, as determined by principal diagnosis (ICD-10AM and obtained from the Western Australian (WA Hospital Morbidity Dataset for 10 financial years from 1999–2000 to 2008–2009. Various risk indicators, including age, gender, Indigenous status, insurance status, hospital area, hospital type,and length of stay were also analysed. Results Out of 26,294 cases of in-hospital care, Indigenous children comprised 4.7per cent(n=1,226, while the non-Indigenous children comprised 95.3 per cent(n=25,068.The majority of the children, nearly 98.8 per cent were admitted for chronic OM. The children were grouped into three age groups, namely, 0–4 years, 5–9 years, and 10–14 years. Nearly two-thirds of all cases were in the 0–4-year age group.Significantly more non-Indigenous (51per cent than Indigenous children (2-percent had private health insurance. The hospitalisation rates were directly proportional between the number of Indigenous children living in the area and the increasing remoteness of the area along with greater socioeconomic disadvantage. There were 24 per cent more cases from very remote areas compared to highly accessible areas, and there were 60 per cent more cases from the most disadvantaged socioeconomic category, compared with the least disadvantaged category, for Indigenous children. Conclusion These data depict the variations in prevalence of otitis media hospitalisations within the community, as affected by various risk indicators.

    Pietie Horn; Ada Jansen; Derek Yu

    2008-01-01

    The factors influencing academic success of first-year Economics students have received much attention from researchers. Very little attention, however, has been given to the determinants of success of senior Economics students. In the USA, Graunke and Woosley (2005: 367) indicate that college sophomores (second years) face academic difficulties, but this receives little attention in the literature. Economics is an elective subject for second-year students at Stellenbosch University. The acad...

    2011-06-01

    Full Text Available Objective: The aim of the present study was to retrospectively evaluate small-diameter (3.3 mm Straumann® dental implants placed in the maxilla or the mandible over a period of 5 years in function.Materials and Methods: Twenty- eight partially edentulous patients received a total of 48 implants over a 5-year period. After the standard healing period (3 to 6 months, the implants were restored with single-tooth prostheses or fixed partial dentures. All patients were followed according to a strict maintenance program with regular recalls. The cumulative survival rates of implants were analyzed and prosthetic complications were assessed.Results: After 5 years of function, one single 10-mm-long implant in the maxillary premolar region was lost because of recurrent peri-implant infection in a female patient. Two single 10-mm-long maxillary implants placed in the posterior region were lost due to body fracture. The cumulative 5-year survival rate of the implants was 93.75 %. The most common prosthetic complication was loosening of the occlusal screw.Conclusion: Within the limited observation period and the number of patients included in this study, it may be concluded that the use of small-diameter implants appears to be predictable if clinical guidelines are followed and appropriate prosthetic restorations are provided. However, it should be noted that fatigue fracture may occur.

    2015-09-01

    Full Text Available Objective: In this study, we aimed to evaluate the patients who applied to various clinics in our hospital with gastrointestinal complaints in terms of intestinal parasites, retrospectively. Methods: Totally 41967 stool samples of patients applied to Parasitology laboratory in Konya Education and Research Hospital in January 2010-December 2012 were investigated under microscope after multiplexing by native lugol and formol ethyl acetate method. Trichrome dying was performed to the suspected samples. The stool samples, in which Entamoeba histolytica /E.dispar cannot be differentiated, were investigated by ELISA method in order to identify adhesin antigens. Results: Intestinal parasite was determined in 2145 (5.11% of 41.967 patients who applied to our laboratory in 3 years. 39.4%, 44.3% and 16.2% of positive patients were 0-15, 16-50 and >50 years old, respectively. Blastocyctis hominis, Entamoeba spp and Giardia intestinalis were found in 59.9%, 25% and 13.7% of the positive samples, respectively. Entamoeba spp and Giardia intestinalis were found most frequently in 0-15 years old patients, while Blastocyctis hominis was found most frequently in 15-49 years old patients. There was a statistically significant difference between these parasites and age groups (p<0.01. The distribution of the positive cases among the years was found as 6.8% in 2010, 5.4% in 2011, 3.3% in 2012 and there was a statistically significant difference between the years (p<0.01. Conclusion: According to our results, the frequency of parasite infection still maintains its importance, although the frequency was decreased compared to previous years.

    Background Accurate patient identification and specimen labeling at the time of collection are crucial steps in the prevention of medical errors, thereby improving patient safety. Methods All patient specimen identification errors that occurred in the outpatient department (OPD), emergency department (ED), and inpatient department (IPD) of a 3,800-bed academic medical center in Taiwan were documented and analyzed retrospectively from 2005 to 2014. To reduce such errors, the following series of strategies were implemented: a restrictive specimen acceptance policy for the ED and IPD in 2006; a computer-assisted barcode positive patient identification system for the ED and IPD in 2007 and 2010, and automated sample labeling combined with electronic identification systems introduced to the OPD in 2009. Results Of the 2000345 specimens collected in 2005, 1023 (0.0511%) were identified as having patient identification errors, compared with 58 errors (0.0015%) among 3761238 specimens collected in 2014, after serial interventions; this represents a 97% relative reduction. The total number (rate) of institutional identification errors contributed from the ED, IPD, and OPD over a 10-year period were 423 (0.1058%), 556 (0.0587%), and 44 (0.0067%) errors before the interventions, and 3 (0.0007%), 52 (0.0045%) and 3 (0.0001%) after interventions, representing relative 99%, 92% and 98% reductions, respectively. Conclusions Accurate patient identification is a challenge of patient safety in different health settings. The data collected in our study indicate that a restrictive specimen acceptance policy, computer-generated positive identification systems, and interdisciplinary cooperation can significantly reduce patient identification errors.

The objective of this study is to summarize the experience and the outcome of the surgical treatment for pulmonary hamartomas, and to assess the effectiveness and necessity of surgical therapy administered in patients with pulmonary hamatoma as well as clinical and pathological features and long-term follow-up results. Methods This retrospective report has reviewed a 20-years clinical history of surgical treatment for 39 patients with PH from 1985 to 2006. These thirty-nine patients underwent 40 operations as follows: wedge resection (23, enucleation (10, segmentectomy (3, lobectomy (3, and pneumonectomy (1. Results The PH occurred most frequently (78.1% in the patients aged 40 to 60 years and the sex ratio (male/female was 2.25/1 in our series. No postoperative death was encountered. One patient with pleural effusion was cured after thoracentesis. All of these 39 patients were proved with pathologic diagnosis of PH and the popcorn calcification was found in 6 cases before operation. In 38 cases having the mean follow-up of 7.3 years, a patient was operated thrice for regional recurrence. Conclusion Fast frozen section in operation is critical for acquire accurate pathological diagnosis. Due to potential trend of recurrence or malignance, patients with hamartoma should be submitted to a complete evaluation and a regular follow-up.

    2015-03-01

    Full Text Available BACKGROUNDS: Fine needle aspiration cytology is an effective modality for diagnosis of breast lesions. Usually male breast lesions are benign and affect the young male. Most common lesion is gynaecomastia. Male breast cancer accounts for a small proportion of breast cancers. Male breast cancer usually presents at an advanced age. OBJECTIVE: The aim of this study was to examine the nature of male breast lesions and to determine the cytomorphologic patterns of these lesions. MET HODS: five year retrospective study was conducted in our institution and in that 112 patients underwent fine needle aspiration cytology of the palpable breast lump after thorough physical examination. The cytological diagnosis was classified as benign, inf lammatory, malignant and others. RESULTS: In 112 male patients diagnosed with breast lesions, the most common lesion was gynecomastia (103/112, 91.9%, followed by breast cancer (6/112, 5.4%, inflammatory (2/112, 1.8% and apocrine metaplasia (01/112, 0.9 %. Gynecomastia was commonly found in male patients less than 40 years of age, while breast cancer is seen in male patients over 40 years of age

    Sobhan, Mohammadreza; Farshchian, Mahmood; Tamimi, Maryam

    2016-01-01

    Background Autoimmune bullous diseases (ABDs) represent a group of rare, acquired disorders characterized by overlapping features with involvement of the skin and mucous membranes, resistance to treatment, and potential lethality that comprise pemphigus, bullous pemphigoid (BP), epidermolysis bullosa, dermatitis herpetiformis, and linear immunoglobulin A bullous dermatosis. Aim The main aim of this study was to identify the epidemiologic characteristics and clinical courses of these common diseases in Hamadan, Iran. Few surveys have been carried out to demonstrate the whole spectrum of ABDs in the literature. Notably, in Hamadan we are the first. Materials and methods This 13-year retrospective study was designed to evaluate all of documented data obtained from hospitalized patients with ABDs at Farshchian Hospital from October 1999 to October 2012. We collected information on epidemiologic data, clinical aspects, histologic findings, and therapy prescribed. Data were analyzed using SPSS. Results Of 168 patients, 78% had pemphigus. The age of patients at presentation ranged from 1 month to 115 years, with a mean of 47.5±19.93 years. Mucosal or skin involvement of ABDs was statistically significant (P<0.001). The incidence of ABDs differed significantly based on anatomic location (P=0.003). We documented three deaths. Conclusion Compared to previous literature, our findings showed equal epidemiologic properties in Iran. Although pemphigus was the most common ABD followed by BP, it is expected that in line with the global trend, an increase in BP will be driven by population aging in Iran. PMID:26811692

    2011-01-01

    Taking the scholarly activities of 73 doctoral program mentors working at the Chinese Academy of Medical Sciences&Peking Union Medical College(the CAMS&PUMC)as a sample of our investigative survey,we tried using such statistical methods as the analysis of variance(ANOVA),factor analysis and correlation analysis to compare the different characteristics of scholarship assessment of Chinese medical scholars as exhibited in their published papers in domestic and foreign journals.Our research findings show that citations per paper and A-index are more suitable for assessing the highly accomplished senior Chinese medical professionals(e.g.academicians)for their domestic and international scholarship attainment.In contrast,the m-quotient is not deemed appropriate to assess their academic influence both at home and abroad.Upon our further analysis of 6 evaluative indicators,we noticed that these indicators might be applied in two different aspects:One is from the viewpoint of Chinese scholars’academic influence at home,which has been evaluated mainly from the perspective of"total"amount and"average"amount of both publications and citations.The other is from their academic impact embodied by the means of documents retrieved from the Web of Science,which is mainly assessed from the two viewpoints of publications and citations.It is suggested that the accumulated time-length of a given scholar’s active engagement in professional practice in a specific subject area be taken into consideration while assessing a researcher’s performance at home and abroad.

  6. Women in Academic Medicine Leadership: Has Anything Changed in 25 Years?

    Rochon, Paula A; Davidoff, Frank; Levinson, Wendy

    2016-08-01

    Over the past 25 years, the number of women graduating from medical schools in the United States and Canada has increased dramatically to the point where roughly equal numbers of men and women are graduating each year. Despite this growth, women continue to face challenges in moving into academic leadership positions. In this Commentary, the authors share lessons learned from their own careers relevant to women's careers in academic medicine, including aspects of leadership, recruitment, editorship, promotion, and work-life balance. They provide brief synopses of current literature on the personal and social forces that affect women's participation in academic leadership roles. They are persuaded that a deeper understanding of these realities can help create an environment in academic medicine that is generally more supportive of women's participation, and that specifically encourages women in medicine to take on academic leadership positions.

  7. Personality traits measured at baseline can predict academic performance in upper secondary school three years late.

    Rosander, Pia; Bäckström, Martin

    2014-12-01

    The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three-year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, ) - particularly Conscientiousness and Neuroticism - were found to predict overall academic performance, after controlling for general intelligence. Results suggest that Conscientiousness, as measured at the age of 16, can explain change in academic performance at the age of 19. The effect of Neuroticism on Conscientiousness indicates that, as regarding getting good grades, it is better to be a bit neurotic than to be stable. The study extends previous work by assessing the relationship between the Big Five and academic performance over a three-year period. The results offer educators avenues for improving educational achievement. PMID:25257093

    2016-01-01

    Clinically significant pain (CSP) is one of the most common complaints among cancer patients during repeated hospitalizations, and the prevalence ranges from 24% to 86%. This study aimed to characterize the trends in CSP among cancer patients and examine the differences in the prevalence of CSP across repeated hospitalizations. A hospital-based, retrospective cohort study was conducted at an academic hospital. Patient-reported pain intensity was assessed and recorded in a nursing information system. We examined the differences in the prevalence of worst pain intensity (WPI) and last evaluated pain intensity (LPI) of ≥ 4 or ≥ 7 points among cancer inpatients from the 1st to the 18th hospitalization. Linear mixed models were used to determine the significant difference in the WPI and LPI (≥ 4 or ≥ 7 points) at each hospitalization. We examined 88,133 pain scores from the 1st to the 18th hospitalization among cancer patients. The prevalence of the 4 CSP types showed a trend toward a reduction from the 1st to the 18th hospitalization. There was a robust reduction in the CSP prevalence from the 1st to the 5th hospitalization, except in the case of LPI ≥ 7 points. The prevalence of a WPI ≥ 4 points was significantly higher (0.240-fold increase) during the 1st hospitalization than during the 5th hospitalization. For the 2nd, 3rd, and 4th hospitalizations, there was a significantly higher prevalence of a WPI ≥ 4 points compared with the 5th hospitalization. We also observed significant reductions in the prevalence of a WPI ≥ 7 points during the 1st to the 4th hospitalizations, an LPI ≥ 4 points during the 1st to the 3rd hospitalizations, and an LPI ≥ 7 points during the 1st to the 2nd hospitalization. Although the prevalence of the 4 CSP types decreased gradually, it is impossible to state the causative factors on the basis of this observational and descriptive study. The next step will examine the factors that determine the CSP prevalence among cancer

    2016-01-01

    Objectives The purpose of this pilot study was to assess the differences in the attitudes of first and fourth-year medical students regarding careers in academics. We also sought to identify any factors associated with an increased interest in academic medicine. Methods A cross-sectional study was conducted during October 2013 at the University of Louisville.  All first and fourth year medical students were invited to complete an online survey utilizing a survey instrument developed through literature review.  Demographic data and information about background experiences were collected in addition to participants' perceptions regarding careers in academia using a 5-point Likert scale. Participants were also queried about their current interest in a career in academics and the likelihood they would pursue academic medicine. Results Of the 330 potential participants, 140 (42.4%) agreed to participate. Overall, fourth-years reported a higher likelihood of pursuing an academic career than first-years. Research experience, publications, distinction track interest or involvement, and belief that a career in academics would reduce salary potential were positively correlated with reported likelihood of pursuing academic medicine. Conclusions Findings from this pilot study demonstrate differences in interest in academic medicine between junior and senior medical students. Additionally, several factors were associated with a high likelihood of self-reported interest in academic. Based on these findings, efforts to increase medical students’ interest in academic medicine careers could be supported by providing more research and teaching opportunities or distinction track options as a structured part of the medical school curriculum.

    Ballet dancers are high-performance athletes who are particularly susceptible to a wide variety of musculoskeletal injuries. However, they are relatively understudied, and data on their injury rates are lacking. This retrospective study features the largest aggregate data on professional ballet dancers to date and aims to identify the most common diagnoses and areas of injury in this unique population to better direct preventative and clinical practices. The study encompassed a 10-year period from January 2000 to December 2010 of dancers from a single company. Data regarding the dancers' age, gender, location of injury, and diagnosis were collected from workers' compensation claims, company records, and medical records maintained by the treating doctors. These were analyzed to determine metrics on injury incidence, frequency, and diagnosis. Over the 10-year span, 574 injuries occurred. There were approximately 52 dancers per year for a total of 153 who danced at least one complete season during the study period. The average age was 27, and 53% were female. Given turnover with retirement and replacements, the total number of dancer-years was 520, indicating an injury incidence per annum of 1.10 (574 injuries per 520 dancer-years). The most common locations of injury were foot and ankle and the lumbar spine, with the three most common diagnoses making up greater than a third (37%) of the total. As the current largest study in professional ballet, the findings set the benchmark metrics for musculoskeletal injury to the foot, ankle, and lumbar spine sites. Future studies should aim to identify injury risk factors and modalities for prevention of these injuries. PMID:27025450

  12. Institutional Characteristics and the Relationship Between Student's Last-Year University and Final-Year Secondary School Academic Performance.

    M. Evans; Farley, A.

    1998-01-01

    A study of academic results of a student cohort in a diverse faculty of a large multi-campus university indicates that students' first-year performance at university is related to their prior academic achievement at secondary school, both overall and discipline specific, but that the extent and form of the relationship can vary by subject area and institutional secondary school and university characteristics. This may have implications for university selection and specification of prerequisit...

  13. The social ties that bind: social anxiety and academic achievement across the university years.

    Brook, Christina A; Willoughby, Teena

    2015-05-01

    Given that engagement and integration in university/college are considered key to successful academic achievement, the identifying features of social anxiety, including fear of negative evaluation and distress and avoidance of new or all social situations, may be particularly disadvantageous in the social and evaluative contexts that are integral to university/college life. Thus, the purpose of this study was to examine the direct effects of social anxiety on academic achievement, as well as investigate an indirect mechanism through which social anxiety might impact on academic achievement, namely, the formation of new social ties in university. The participants were 942 (71.7 % female; M = 19 years at Time 1) students enrolled in a mid-sized university in Southern Ontario, Canada. Students completed annual assessments of social anxiety, social ties, and academic achievement for three consecutive years. The results from an autoregressive cross-lag path analysis indicated that social anxiety had a significant and negative direct relationship with academic achievement. Moreover, the negative indirect effect of social anxiety on academic achievement through social ties was significant, as was the opposing direction of effects (i.e., the indirect effect of academic achievement on social anxiety through social ties). These findings highlight the critical role that social ties appear to play in successful academic outcomes and in alleviating the effects of social anxiety during university/college. PMID:25691148

  15. IgA Nephropathy: A Twenty Year Retrospective Single Center Experience

    Jacob Rube

    2009-01-01

    Full Text Available IgA nephropathy (IgAN is a common glomerular disease whose etiology is unknown. Previous studies have described the clinical and laboratory features but none have specifically compared patients during different time periods. This 20 year retrospective study was performed to assess trends in the severity of IgAN from 1989–2008. We reviewed 57 patient charts that contained a confirmed biopsy diagnosis of IgAN and recorded data at the time of diagnosis and the final follow-up appointment. Clinical data included physical examination, urine, and blood tests. Patients were separated into two cohorts, Cohort 1 1989–1998 and Cohort 2 1999–2008. An increase in severity was noted in Cohort 2 based on a significantly higher Up/c and lower serum albumin level. Other prognostic indicators including GFRe, hematocrit, and glomerular injury score also demonstrated a trend towards more severe disease over the past 20 years. The patients in both Cohorts received similar treatments and had comparable renal function at the last follow-up visit. Based on our findings, we suggest that although a kidney biopsy is required to diagnose IgAN, the procedure may not be necessary in patients clinically suspected of having the disease but who have normal kidney function and minimal urine abnormalities.

    Pemphigus vulgaris (PV), an autoimmune blistering disease involving the skin and mucosa, is traditionally considered to be prevalent among Jews, particularly those of Ashkenazi origin. Israel, where the Ashkenazi and non-Ashkenazi Jewish population live alongside a large Arab minority, is a particularly interesting place for epidemiological studies of PV. To characterise the epidemiological and clinical parameters of PV patients from a single tertiary medical centre in Israel. Data was retrieved retrospectively from the medical records of newly diagnosed PV patients referred to the Sheba Medical Center between 1980 and 2009. A total of 290 PV patients were diagnosed during the study period. The mean age at diagnosis was 49.7 years (range: 10-92 years) and a female predominance was identified (1.54:1; pcountries reveal variations in the clinical and epidemiological characteristics of the disease. The epidemiology of PV in Israel, a Middle-Eastern country with a Western lifestyle and a diverse ethnic population, shows some characteristics that represent an "admixture" between European and Middle-Eastern or Asian countries. The associated comorbidities of PV emphasize the need for dermatologists to keep a high index of suspicion and actively evaluate patients to determine their presence. PMID:27300747

  17. Flipping a Dental Anatomy Course: A Retrospective Study Over Four Years

    2016-01-01

    Full Text Available Flipped classrooms have been successfully used to increase student engagement and support student learning in a range of educational fields, including health education. These advantages for student learning supported implementation of the flipped classroom in introductory sciences and preclinical courses in dental education. We report on a 4-year retrospective study which compared two methods of delivery of a first-year dental anatomy course. The first method used the traditional method, consisting of face to face contact teaching hours, which was compared to a partial flipped classroom, where lecture contact was maintained but practical classes were flipped. A series of online videos demonstrating different practical tasks such as wax carving and tooth identification. An online digital library and online quizzes for self-reflected learning were developed and trialled. Students’ Evaluations of Course (SEC and students’ overall performance in practical and theoretical assessments were used to evaluate the impact on student engagement and success, respectively, after implementation of the modified course offerings. This study evidences the success of the transition to a partially flipped course design. Careful design and consideration of implementation of the flipped classroom method in dental education are recommended to ensure that there is reliable availability of online resources and dedicated teaching staff for construction of resources and delivery of relevant in-class activities.

  18. A 40-year retrospective European radon flux inventory including climatological variability

    López-Coto, I.; Mas, J. L.; Bolivar, J. P.

    2013-07-01

    In this work, a 40-year retrospective European radon flux inventory has been calculated. Average values of the radon exhalation rate, probability distributions and seasonal fluctuations have been obtained. To achieve this, a numerical model of radon transport through finite, heterogeneous and porous media has been implemented, enabling us to calculate the radon exhalation rate of European soils with a horizontal resolution of 0.5' (˜1 km). Geological, geochemical and climatological parameters derived from European and international databases (FOREGS, HWSD, ERA-40) have been coupled to the model. The theoretical model is based on the fundamental equation of radon transport in porous media, taking into account the dependency of the transport coefficient on temperature and humidity. It also includes a simple model that evaluates the effect of snow cover. In general, the results show wide variations depending on location and season of the year, with a spatial standard deviation close to the annual average value (30 Bq m-2 h-1) In turn, the seasonal deviation is about 25% of the annual average value. The inventory can be easily integrated into atmospheric transport models acting as baseline that could be used for policy decisions regarding the identification of areas with a high risk of exposure to radon. The gridded data are available for the scientific community upon request. The limitations and sources of errors and uncertainties of the model are also discussed in detail.

    2015-01-01

    Full Text Available Background. Short implants have become popular in the reconstruction of jaws, especially in cases with limited bone height. Shorter implants, those with locking tapers and plateau root shapes, tend to have longer survival times. We retrospectively investigated the cumulative survival rates of Bicon short implants (<8 mm according to patient variables over a 5-year period. Materials and Methods. This study included 111 consecutively treated patients with 371 implants supporting fixed or removable prosthetics. Data were evaluated to acquire cumulative survival rates according to gender, age, tobacco use, surgical procedure, bone quality, and restoration type. Statistics were performed using chi-square, Mann-Whitney, and Kruskal Wallis H tests. Results. The survival rate was 97.3% with, on average, 22.8 months of follow-up. Patients older than 60 years had higher failure rate than the other age groups (P<0.05. Placed region, age, and bone quality had adverse effects on survival rate in the <8 mm implant group with statistically significant difference (P<0.05. Conclusions. Approximately 23-month follow-up data indicate that short implants with locking tapers and plateau-type roots have comparable survival rates as other types of dental implants. However, due to limitations of study, these issues remain to be further investigated in future randomized controlled clinical trials.

    Full Text Available Abstract Background The West African sub-region has poor health infrastructure. Mechanical valve replacement in children from such regions raises important postoperative concerns; among these, valve-related morbidity and complications of lifelong anticoagulation are foremost. Little is known about the long-term outcome of mechanical valve replacement in West Africa. We sought to determine the outcome of mechanical valve replacement of the left heart in children from this sub-region. Method We conducted a retrospective review of all consecutive left heart valve replacements in children ( Results One hundred and fourteen patients underwent mitral valve replacement (MVR, aortic valve replacement (AVR or mitral and aortic valve replacements (MAVR. Their ages ranged from 6-18 years (13.3 ± 3.1 years. All patients were in NYHA class III or IV. Median follow up was 9.1 years. MVR was performed in 91 (79.8% patients, AVR in 13 (11.4% and MAVR in 10 (8.8% patients. Tricuspid valve repair was performed concomitantly in 45 (39.5% patients. There were 6 (5.3% early deaths and 6 (5.3% late deaths. Preoperative left ventricular dysfunction (ejection fraction Conclusion Mechanical valve replacement in West African children has excellent outcomes in terms of mortality, valve-related events, and reoperation rate. Preoperative left ventricular dysfunction is the primary determinant of mortality within the first 2 years of valve replacement. The risk of valve-related complications is acceptably low. Anticoagulation is well tolerated with a very low risk of bleeding even in this socioeconomic setting.

    2004-11-01

    Full Text Available Abstract Background The purpose of this study was to investigate the indications for and approach to hysterectomy at Kingston General Hospital (KGH, a teaching hospital affiliated with Queen's University at Kingston, Ontario. In particular, in light of current literature and government standards suggesting the superiority of vaginal versus abdominal approaches and a high number of concurrent oophorectomies, the aim was to examine the circumstances in which concurrent oophorectomies were performed and to compare abdominal and vaginal hysterectomy outcomes. Methods A retrospective chart audit of 372 consecutive hysterectomies performed in 2001 was completed. Data regarding patient characteristics, process of care and outcomes were collected. Data were analyzed using descriptive statistics, t-tests and linear and logistic regression. Results Average age was 48.5 years, mean body mass index (BMI was 28.6, the mean length of stay (LOS was 5.2 days using an abdominal approach and 3.0 days using a vaginal approach without laparoscopy. 14% of hysterectomies were performed vaginally, 5.9% were laparoscopically assisted vaginal hysterectomies and the rest were abdominal hysterectomies. The most common indication was dysfunctional or abnormal uterine bleeding (37%. The average age of those that had an oophorectomy (removal of both ovaries was 50.8 years versus 44.3 years for those that did not (p Conclusions A significant reduction in LOS was found using the vaginal approach. Both the patient and the health care system may benefit from the tendency towards an increased use of vaginal hysterectomies. The audit process demonstrated the usefulness of an on-going review mechanism to examine trends associated with common surgical procedures.

    Full Text Available Mohammadreza Sobhan, Mahmood Farshchian, Maryam TamimiPsoriasis Research Center, Department of Dermatology, Farshchian Hospital, Hamadan University of Medical Sciences, Hamadan, IranBackground: Autoimmune bullous diseases (ABDs represent a group of rare, acquired disorders characterized by overlapping features with involvement of the skin and mucous membranes, resistance to treatment, and potential lethality that comprise pemphigus, bullous pemphigoid (BP, epidermolysis bullosa, dermatitis herpetiformis, and linear immunoglobulin A bullous dermatosis.Aim: The main aim of this study was to identify the epidemiologic characteristics and clinical courses of these common diseases in Hamadan, Iran. Few surveys have been carried out to demonstrate the whole spectrum of ABDs in the literature. Notably, in Hamadan we are the first.Materials and methods: This 13-year retrospective study was designed to evaluate all of documented data obtained from hospitalized patients with ABDs at Farshchian Hospital from October 1999 to October 2012. We collected information on epidemiologic data, clinical aspects, histologic findings, and therapy prescribed. Data were analyzed using SPSS.Results: Of 168 patients, 78% had pemphigus. The age of patients at presentation ranged from 1 month to 115 years, with a mean of 47.5±19.93 years. Mucosal or skin involvement of ABDs was statistically significant (P<0.001. The incidence of ABDs differed significantly based on anatomic location (P=0.003. We documented three deaths.Conclusion: Compared to previous literature, our findings showed equal epidemiologic properties in Iran. Although pemphigus was the most common ABD followed by BP, it is expected that in line with the global trend, an increase in BP will be driven by population aging in Iran.Keywords: autoimmune bullous disease, pemphigus, prevalence

  3. Cumulative ionizing radiation exposure in patients with end stage kidney disease: a 6-year retrospective analysis.

    Coyle, Joe

    2011-08-13

    OBJECTIVE: To quantify cumulative exposure to ionizing radiation in patients with end stage kidney disease (ESKD). To investigate factors which may be independently associated with risk of high cumulative effective dose (CED). MATERIALS AND METHODS: The study had local institutional review board ethical approval. We conducted a retrospective study of 394 period prevalent ESKD patients attending a single tertiary referral centre between 2004 and 2009. Patient demographics were obtained from case records. Details of radiological investigations were obtained from the institutional radiology computerized database. CED was calculated using standard procedure specific radiation levels. High exposure was defined as CED > 50 mSv, an exposure which has been reported to increase cancer mortality by 5%. Data were compared using Pearson χ(2) and Mann-Whitney U test or Kruskal-Wallis tests. RESULTS: 394 patients were followed for a median of 4 years (1518 patient years follow-up). Of these 63% were male. Seventeen percent of patients had a CED of >50 mSv. Computed tomography (CT) accounted for 9% of total radiological studies\\/procedures while contributing 61.4% of total study dose. Median cumulative dose and median dose per patient year were significantly higher in the hemodialysis (HD) group (15.13 and 5.79 mSv, respectively) compared to the post-transplant group (2.9 and 0.52 mSv, respectively) (P < 0.001). CONCLUSION: ESKD patients are at risk of cumulative exposure to significant levels of diagnostic radiation. The majority of this exposure is imparted as a result of CT examinations to patients in the HD group.

    Narayanan Rajmohan L

    2011-05-01

    Full Text Available Abstract Background Dengue re-emerges in Singapore despite decades of effective vector control; the infection predominantly afflicts adults. Severe dengue not fulfilling dengue hemorrhagic fever (DHF criteria according to World Health Organization (WHO 1997 guideline was increasingly reported. A new WHO 2009 guideline emphasized warning signs and a wider range of severe dengue manifestations. We aim to evaluate the utility of these two guidelines in confirmed adult dengue fatalities. Methods We conducted a multi-center retrospective chart review of all confirmed adult dengue deaths in Singapore from 1 January 2004 to 31 December 2008. Results Of 28 adult dengue deaths, median age was 59 years. Male gender comprised 67.9% and co-morbidities existed in 75%. From illness onset, patients presented for admission at a median of 4 days and death occurred at a median of 12 days. Intensive care admission was required in 71.4%. Probable dengue was diagnosed in 32.1% by WHO 1997 criteria and 78.6% by WHO 2009. The earliest warning sign was persistent vomiting at a median of 1.5 days. Hematocrit change ≥20% concurrent with platelet count Conclusions In our adult fatal dengue cohort, WHO 2009 criteria had higher sensitivity in diagnosing probable dengue and severe dengue compared with WHO 1997. As warning signs, persistent vomiting occurred early and hematocrit change ≥20% concurrent with platelet count

  6. Metamemory prediction accuracy for simple prospective and retrospective memory tasks in 5-year-old children.

    Kvavilashvili, Lia; Ford, Ruth M

    2014-11-01

    It is well documented that young children greatly overestimate their performance on tests of retrospective memory (RM), but the current investigation is the first to examine children's prediction accuracy for prospective memory (PM). Three studies were conducted, each testing a different group of 5-year-olds. In Study 1 (N=46), participants were asked to predict their success in a simple event-based PM task (remembering to convey a message to a toy mole if they encountered a particular picture during a picture-naming activity). Before naming the pictures, children listened to either a reminder story or a neutral story. Results showed that children were highly accurate in their PM predictions (78% accuracy) and that the reminder story appeared to benefit PM only in children who predicted they would remember the PM response. In Study 2 (N=80), children showed high PM prediction accuracy (69%) regardless of whether the cue was specific or general and despite typical overoptimism regarding their performance on a 10-item RM task using item-by-item prediction. Study 3 (N=35) showed that children were prone to overestimate RM even when asked about their ability to recall a single item-the mole's unusual name. In light of these findings, we consider possible reasons for children's impressive PM prediction accuracy, including the potential involvement of future thinking in performance predictions and PM.

    Full Text Available Background. Corneal blindness from healed infected keratitis is one of the most preventable causes of monocular blindness in developing countries, including Malaysia. Our objectives were to identify the causative fungi, predisposing risk factors, the proportion of correct clinical diagnosis, and visual outcome of patients treated in our hospital. Methods. A retrospective review of medical and microbiology records was conducted for all patients who were treated for fungal keratitis at Hospital Universiti Sains Malaysia from January 2007 until December 2011. Results. Forty-seven patients (47/186, 25.27% were treated for fungal keratitis during the study period. This demonstrated that the incidence of fungal keratitis has increased each year from 2007 to 2011 by 12.50%, 17.65%, 21.21%, 26.83%, and 28.57%, respectively. The most common predisposing factors were injury to the eye followed by use of topical steroid, and preexisting ocular surface disease. Fusarium species were the most common fungal isolated, followed by Candida species. Clinical diagnosis of fungal keratitis was made in 26 of the 41 (63.41% cases of positive isolates. Of these, in eleven cases (23.40% patients required surgical intervention. Clinical outcome of healed scar was achieved in 34 (72.34% cases. Conclusions. The percentage of positive fungal isolated has steadily increased and the trend of common fungal isolated has changed. The latest review regarding fungal keratitis is important for us to improve patients' outcome in the future.

    Orofacial pain is often difficult to diagnose and treat. However, there have been few reports on the clinical observation of dental patients with orofacial pain. We retrospectively investigated the characteristics of 221 dental patients who had suffered from persistent orofacial pain. Data were collected from the outpatient medical records in our clinic over the past 12 years. More than half of the patients (53.8%) had suffered with pain for more than 6 months from pain onset until the first visit to our clinic. The main diagnoses were neuropathic pain (30.3%), myofascial pain (23.5%), psychogenic pain (20.4%), odontogenic toothache (17.2%), and others (7.7%) such as temporomandibular disorders and glossitis. The treatments included pharmacotherapy, splint therapy, and others such as nerve block, dental treatment, physiotherapy, and/or psychotherapy. Excluding the patients (52 of 221 initially enrolled patients) with unknown responses to treatment, 65.7% showed remission or a significant improvement in pain in response to treatment. Although only a small group of patients had odontogenic toothache, the rate of improvement was highest for this disorder. In conclusion, early consultation with a dentist is useful to prevent chronicity of odontogenic pain and to make a differential diagnosis in patients with orofacial pain. PMID:25338483

    1999-06-01

    Full Text Available Coronary artery disease is one of the leading causes of morbidity and mortality especially in the indusirialzcd societies. This retrospective study was carried out on 385 patients who were referred to Shariati and Jamaran Hospitals from 1992 till 1997 and who underwent coronaty artery bypass grafting. The objective was to obtain a descriptive analysis of the important factors in this population and to draw a comparison betweent the two genders and to draw genders regarding these variables. The data were obtained from patients' files, angiography and operation notes; 82.9% of the study population were of male. The mean age of women was higher than men by 2.2years. The most common risk factors among the male gender were found to be smoking, hyperlipedemia, hypercholesterolemia and hypertension. Except for smoking which was omitted in women, all other risk factors showed a comparative low prevalence in this gender. Most patients (93.37% fell in group II and III of functional class as per NYHA classification and the most frequent signs and symptoms on admission being chest pain (81.5% and dyspnea (11.2%. The affected vessels in order of frequency were the left anterior descending, the right coronary and the circumflex arteries respectively. The average number of grafts utilized were 3 in the entire population. Overall mortality recorded was 2.1%.

  10. Mortality in perforated duodenal ulcer depends upon pre-operative risk: a retrospective 10-year study.

    Larkin, J O

    2012-01-31

    INTRODUCTION: Most patients presenting with acutely perforated duodenal ulcer undergo operation, but conservative treatment may be indicated when an ulcer has spontaneously sealed with minimal\\/localised peritoneal irritation or when the patient\\'s premorbid performance status is poor. We retrospectively reviewed our experience with operative and conservative management of perforated duodenal ulcers over a 10-year period and analysed outcome according to American Society of Anesthesiologists (ASA) score. METHODS: The records of all patients presenting with perforated duodenal ulcer to the Department of Surgery, Mayo General Hospital, between January 1998 and December 2007 were reviewed. Age, gender, co-morbidity, ASA-score, clinical presentation, mode of management, operative procedures, morbidity and mortality were considered. RESULTS: Of 76 patients included, 48 (44 operative, 4 conservative) were ASA I-III, with no mortality irrespective of treatment. Amongst 28 patients with ASA-score IV\\/V, mortality was 54.5% (6\\/11) following operative management and 52.9% (9\\/17) with conservative management. CONCLUSION: In patients with a perforated duodenal ulcer and ASA-score I-III, postoperative outcome is uniformly favourable. We recommend these patients have repair with peritoneal lavage performed, routinely followed postoperatively by empirical triple therapy. Given that mortality is equivalent between ASA IV\\/V patients whether managed operatively or conservatively, we suggest that both management options are equally justifiable.

    Objective To determine the characteristics of women with maternal tetanus, pattern of presentation and outcome of management.Methods A total of 19 women were managed with maternal tetanus between 1990 and 2005 from the University College Hospital in Ibadan Nigeria. A retrospective study was performed. The medical records of all women managed as a case of maternal tetanus were retrieved from the central record department of the hospital The pattern of presentation, characteristics of women, the duration of hospital admission, tetanus toxoid immunization, and outcome of care were measured.Results The records of 18 women managed were analyzed. The mean age at presentation was 25.2±5.3 years. The patients were mostly single, nulliparous and had primary school education. The maternal tetanus cases seen mainly complicated induced abortion while 5 and 2 other cases were due to childbirth complication and leg wound respectively. The portal of entry of the remaining 3 cases could not be ascertained.None of the patient managed had complete immunization schedule. The average duration of admission was 11.2±6. 7 d. Five women had intensive care with 3 of them requiring ventilatory support. The case fatality rate was 66. 7%. The only factor that significantly improved survival was presence of generalized spasm at presentation (P=0. 006) Conclusion The occurrence of maternal tetanus is a reflection of low quality of health care delivery and lack or inefficient routine immunization coverage in any community.

    Pilocytic astrocytomas (PA) are benign neoplasms commonly located in the cerebellum with a peak incidence in the first two decades of life. PA occurrence in adults is rare and very little information is available in the literature about tumour characteristics in this population. This study retrospectively identified 20 adults with PA. The characteristics of the tumour, treatment modalities and patient outcomes are discussed, as well as identifying factors that may be associated with worse prognosis. The mean age at diagnosis was 27 years. The majority of PA were located in the posterior fossa. Other tumour locations included the cerebral hemispheres, brainstem, tectal plate and optochiasmatic region (optic chiasm, hypothalamus and third ventricle). All patients in this study underwent surgery, two received adjuvant chemotherapy and one received adjuvant radiotherapy. Tumour recurrence occurred in six patients and two eventually died from the disease. When achieved, complete tumour resection was found to be curative. Tumour location affects extent of surgical resection; tumours in inaccessible locations were associated with higher rates of recurrence. Overall survival and progression free survival rates were 87% and 60% respectively. The degree of surgical resection and tumour location were found to affect prognosis. Unfavourable outcomes were observed in these adults with PA compared to those expected for a younger population, suggesting a possible association between age and outcome. PMID:25065843

    This study shares data on 417 patients with genetic disorders of skeleton including 10 fetal autopsies encountered in a 5-year period at a tertiary university hospital in Ankara, Turkey. We included patients with osteochondrodysplasias, excluding overgrowth syndromes, dysostoses, and craniofacial syndromes. When grouped according to the "International Skeletal Dysplasia Society 2010 classification" the most frequent group is "FGFR3 group" (achondroplasia). "Decreased bone density group" takes the second place, consistent with the literature. We also demonstrated, a relatively higher frequency of recessively inherited skeletal dysplasias when the diagnosis is an entity other than achondroplasia or osteogenesis imperfecta. The literature on the incidence of genetic disorders of skeleton from the Middle East and Eastern Mediterranean is limited to fetal and neonatal autopsies or birth prevelance reports. The higher rate of consanguineous marriages which increases the frequency of autosomal recessive entities makes it difficult to apply data from other parts of the world. Total consanguinity rate among parents in our study was 53% and there were regional differences. The highest (79%) was among parents from South-east Anatolia. This study is the first broad retrospective analysis of genetic disorders of skeleton from our region. We aim to provide a descriptive source for future studies and discuss our findings in comparison to reports from other parts of the world. PMID:25931420

    Background. Corneal blindness from healed infected keratitis is one of the most preventable causes of monocular blindness in developing countries, including Malaysia. Our objectives were to identify the causative fungi, predisposing risk factors, the proportion of correct clinical diagnosis, and visual outcome of patients treated in our hospital. Methods. A retrospective review of medical and microbiology records was conducted for all patients who were treated for fungal keratitis at Hospital Universiti Sains Malaysia from January 2007 until December 2011. Results. Forty-seven patients (47/186, 25.27%) were treated for fungal keratitis during the study period. This demonstrated that the incidence of fungal keratitis has increased each year from 2007 to 2011 by 12.50%, 17.65%, 21.21%, 26.83%, and 28.57%, respectively. The most common predisposing factors were injury to the eye followed by use of topical steroid, and preexisting ocular surface disease. Fusarium species were the most common fungal isolated, followed by Candida species. Clinical diagnosis of fungal keratitis was made in 26 of the 41 (63.41%) cases of positive isolates. Of these, in eleven cases (23.40%) patients required surgical intervention. Clinical outcome of healed scar was achieved in 34 (72.34%) cases. Conclusions. The percentage of positive fungal isolated has steadily increased and the trend of common fungal isolated has changed. The latest review regarding fungal keratitis is important for us to improve patients' outcome in the future. PMID:23304138

    2015-01-01

    Full Text Available Background: Leprosy has been officially eliminated from India since December, 2005; still, there are districts and blocks reporting high prevalence indicating ongoing transmission. The present study aimed at determining the current clinical profile of leprosy from a tertiary level hospital in Delhi. Materials and Methods: A retrospective, record-based study was carried out on patients diagnosed and registered in the leprosy clinic of a tertiary level teaching hospital in East district of Delhi (April 2007 to March 2012. Data regarding demographic details, clinical features, treatment started and complications was analyzed. Results: A total of 849 patients were registered over a 5-year period, with M: F ratio of 2.3:1. 9.3% were children (ͳ14 years. 54.3% patients were immigrants from adjoining states. Multibacillary leprosy was the most common clinical type (86.9%. Borderline tuberculoid leprosy was the most frequent morphologic type, seen in 56.3% followed by borderline-borderline (1.5%, borderline lepromatous (24.9%, lepromatous leprosy (8.1%, pure neuritic (8.1%, histoid and indeterminate leprosy (0.5% each. 37.4% patients presented in reaction (Type I in 30.4% cases and Type II in 7% cases. WHO grade II deformities were diagnosed in 37.9% with claw hand being the most common paralytic deformity (23.3% cases. Conclusion: Our study offers insight into the current status of the disease in an area of otherwise low prevalence. It is seen that despite statistical elimination, multibacillary disease, leprosy reactions and deformities are commonly seen as presenting manifestations, in contrast to national projected trends. Delhi′s unique demography with a high degree of migrant workers, presenting to our center (near border location could be a possible contributing factor towards these aberrations. It highlights the need for continuation of targeted leprosy control activities and active case detection.

    Radiologically inserted gastrostomy (RIG) is an established way of maintaining enteral nutrition in patients who cannot maintain nutrition orally. The purpose of this study was to evaluate the safety and efficacy of primary placement of a wide bore button gastrostomy in a large, varied patient population through retrospective review. All patients who underwent gastrostomy placement from January 1, 2004 to January 1, 2009 were identified. 18-Fr gastrostomy buttons (MIC-Key G) were inserted in the majority. Follow-up ranged from 6 months to 4.5 years. A total of 260 patients (M:F 140:120, average age 59.2 years) underwent gastrostomy during the study period. Overall success rate for RIG placement was 99.6 %, with success rate of 95.3 % for primary button insertion. Indications included neurological disorders (70 %), esophageal/head and neck malignancy (21 %), and other indications (9 %). Major and minor complication rates were 1.2 and 12.8 %, respectively. Thirty-day mortality rate was 6.8 %. One third of patients underwent gastrostomy reinsertion during the study period, the main indication for which was inadvertent catheter removal. Patency rate was high at 99.5 %. The maximum number of procedures in any patient was 8 (n = 2), and the average tube dwell time was 125 days. Primary radiological insertion of a wide bore button gastrostomy is a safe technique, with high success rate, high patency rate, and low major complication rate. We believe that it is feasible to attempt button gastrostomy placement in all patients, once tract length is within limits of tube length. If difficulty is encountered, then a standard tube may simply be placed instead.

    Introduction Both, the renal pelvis and the ureter, are affected by developmental, reactive and neoplastic disorders, though rare in incidence. Aim This series of cases were analysed to study the clinicopathological characteristics of the common and comparatively rare lesions involving the renal pelvis and pelviureteric junction. Materials and Methods A retrospective collection of 476 nephrectomies and pelviureteric junction resections, received over a period of 13 years from 2001 to 2013 was done. The patients’ clinical details were obtained and the histopathological findings reviewed. The lesions were classified into non-neoplastic and neoplastic categories. Results Primary involvement of the renal pelvis and pelviureteric junction was seen in 105 of 476 specimens. The mean age was 54.5 years with a male to female ratio of 2.2:1. The non-neoplastic lesions accounted for 76.2% of cases with a majority being pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy (68.6%) causing hydronephrosis. Urothelial carcinomas were encountered in 20% of the cases. A majority of the urothelial carcinomas were infiltrative (81%) and high grade (71%) tumours. Conclusion Renal pelvis, a conduit to propel urine, can be the site for numerous disorders. Non-neoplastic lesions were more common than neoplasms. Pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy was the commonest lesion in our study. In the neoplastic category, urothelial carcinoma was most common. However, rare lesions such as hamartomatous fibroepithelial polyp, Von Brunn’s nests, flat urothelial hyperplasia and intramuscular haemangioma of upper ureter at the pelviureteric junction were encountered along with occasional cases of tuberculosis and squamous cell carcinomas.

    Venlafaxine is commonly used in the United States for approved and non-Food and Drug Administration-approved indications in adults. It is used off-label to treat children for psychiatric diagnoses. The aim of the study was to describe venlafaxine toxicities in children and to identify the venlafaxine dose per weight that correlates with toxicities. An 11-year retrospective study of venlafaxine ingestion in children was performed using the California Poison Control System (CPCS) database. Data was extracted from phone calls received by CPCS clinicians and follow-up phone calls made to assess the patient's progress in a health-care setting. Inclusion criteria were venlafaxine ingestion cases reported to CPCS between January 2001 and December 2011, children aged 20 years and under, venlafaxine as the only ingested substance, managed in a health-care facility, and followed to a known outcome. Two hundred sixty-two cases met the study criteria. Common presentations included gastrointestinal (14.9%), altered mental status (13.7%), and tachycardia (13.4%). The majority of the cases resulted in no effect (51.5%) or minor effect (19.9%). The average estimated dose per weight was 18.3 mg/kg in all patients and 64.5 mg/kg in those experiencing moderate-to-severe adverse effects. Seizures occurred in only 4 of the 262 cases at doses ranging from 1500 to 7500 mg. Although the estimated dose per weight exceeded 10 mg/kg for the majority of the cases, only 12 cases resulted in moderate or severe outcomes. The majority of venlafaxine ingestion cases in children resulted in either no clinical effects or minor clinical effects. PMID:26351291

    2015-01-01

    Full Text Available Background: Retroperitoneal fibrosis (RPF is an uncommon disease that is characterized by development of fibrosclerotic tissues involving retroperitoneal structures. This study aimed to investigate the clinical features of 30 patients with RPF in a single center in Beijing in a 10-year period. Methods: We retrospectively analyzed clinical data on demographic characteristics, clinical manifestations, laboratory findings, radiological findings, modalities of treatments, outcomes and prognosis of 30 patients with RPF. Patients were treated in Beijing Chao-Yang Hospital between January 2003 and December 2013. Results: The mean age of patients with RPF was 56.7 ± 14.4 years. Twenty-three patients were men and seven patients were women. Acute phase reactants were elevated in most patients. Rheumatic factor was positive in 4/25 (16.0% patients, and antinuclear antibody was positive in 6/22 (27.3% patients. Elevation of IgG4 was observed in 9/22 (40.9% patients. The most common type was I + III (n = 13, followed by I + II + III (n = 12. Five patients undertook an 18 F-fluoro-deoxy-D-glucose positron emission tomography examination and increased uptake was detected in four patients. Eight patients received combination therapy with glucocorticoids and tamoxifen. Surgical intervention treatments included intraureteral double-J stent implantation (n = 26, percutaneous nephrostomy (n = 2, open ureterolysis and intraperitonealization of the ureters (n = 5 and laparoscopic ureterolysis and intraperitonealization of the ureters (n = 5. Three patients underwent hemodialysis because of renal failure. Conclusions: Clinical characteristics of RPF patients in our study are similar to those previously reported. Steroids and immunosuppressive therapy combined with ureterolysis could be a viable choice of treatment for RPF. More prospective, multi-center studies with a longer follow-up are warranted.

    Frequent localization of facial malignancies in the nasal area and their required complete surgical extirpation pose a significant challenge to the plastic surgeon, who is called to perform a suitable delicate reconstruction of produced nasal skin defects. The present study was aimed to examine the role of tumor characteristics in the prognosis of patients with nasal skin cancer undergoing surgical management.A retrospective review of 1795 patients operated on for nasal cutaneous neoplasms during a 26-year period is presented in our study. Descriptive statistics were appropriately calculated; multivariate Cox regression analysis was performed regarding the possible risk factors for recurrence. Only those with a complete follow-up were included in the study. The mean age of our study population was 66.7 years with a male majority (52.4%). Basal cell carcinoma appeared as the most common histological type (87.7%), followed by squamous cell carcinoma (7.9%); the latter correlated with poor prognosis.The nasal sidewalls were the most frequent lesion location (29.8%), followed by the alae (27.8%), dorsum (21.7%), and tip (19.3%). The columella was very rarely affected (0.5%) but was associated with increased recurrence [hazard ratio, 4.74; 95% confidence interval (CI), 1.12-20.00; P = 0.034]. Most patients were treated with elliptical excision and direct closure (58.7%). Local flaps (31.0%) and skin grafting (9.0%) proved very reliable surgical options, especially for larger, high-risk lesions. Recurrence transpired in 46 patients (2.6%) and 4 skin cancer-related deaths occurred.Surgical modality of choice should be individualized and carefully adjusted to patients' needs. Moreover, more elective techniques, such as Mohs micrographic surgery or cumulative therapeutic approaches, like irradiation, should be examined as a beneficial aid to confront high-risk malignancies.

    Full Text Available Each country faces a continuing challenge to collect enough blood to meet the national needs. According to WHO, there should be at least 20 blood donations per 1,000 population for developing countries, in Kazakhstan this indicator was only 16.8 in 2011. Thus, we conducted an epidemiological assessment and drew a map of the regional distribution of blood and plasma donations in Kazakhstan during the years 2000-2011.The retrospective study was conducted from 2000 to 2011. Data on blood and its components donations were acquired from the Ministry of Health (annual statistical reporting form N° 39.During 2000-2011, number of blood donors decreased to 17.4% and blood donations to 6.3%. The proportion of non-remunerated blood donations and donors decreased from 97.6% to 77.9% and 97.9% to 87.7%, respectively. The paid donations had the opposite trend. Number of plasma donors increased in 2.1 times, plasma donations in 2.4 times, nevertheless the proportion of non-remunerated plasma donations decreased from 60.1% to 29.8%. The average number of blood donations per 1,000 population decreased from 19.8 (2000 to 16.8 (2011, plasma donations increased from 1.4 to 3.1. Regionally, annual average rates of blood and plasma donations per 1,000 population over 12 years varied greatly.This is the first study conducted in Kazakhstan to provide detailed information, including the regional characteristics of blood and plasma donations over an extended period of time, which can be used in blood transfusion services work.

    2016-07-01

    Full Text Available BACKGROUND Ovarian tumours being second most common gynaecological cancer in India account for 30% of all cancers of female genital tract. Study conducted to determine relative frequencies of various histological types based on WHO classification and their age distribution with particular emphasis on surface epithelial tumours. This study is undertaken to find out the frequency of incidence of different histopathological subtypes with particular emphasis on surface epithelial tumours and age distribution of ovarian tumours in our institute located in coastal Andhra Pradesh. METHODS This is a retrospective study of 100 cases of ovarian neoplasms collected during a period of 3 years from June 2013 to May 2016 from the Department of Pathology, Katuri Medical College and Hospital, Chinakondrupadu, Guntur, A. P, India. The patients attending our hospital are mostly from rural areas around. Paraffin blocks of all 100 ovarian neoplasms retrieved. Complete clinical and radiological findings analysed from our records. RESULTS The tumours are grouped according to the nature of tumour whether benign or borderline or malignant according to cell of origin, histological subtyping, and age group. Surface epithelial tumours are the most common. Benign tumours outnumber the malignant tumours. Benign ovarian tumours showed a peak in 21-40 Yrs. age group and malignant in the age group of 41- 60 Yrs. Results of our study compared with other studies. CONCLUSION Because of the geographic location, poverty, and illiteracy, patients seek medical advice late. So, awareness among public by health education, passive surveillance, and community screening facility will be helpful in early detection of ovarian neoplasms.

    Full Text Available Background and Design: Allergic contact dermatitis is a delayed type hypersensitivity reaction to allergens in individuals who were sensitized with same allergens before. The causative allergens may change in time as well as vary among geographical and population based differences. Materials and Methods: The characteristics of 169 patients-107 (63.3% male, 62 (36.7% female, who patch tested between 2011- 2014 with allergic contact dermatitis diagnosis and test results were retrospectively analysed. Results: The mean age of all patients who had the most frequent occupation as service sector/house wife (26.6% were 41.06 years and the mean disease duration of all patients was 19.5 months. The most frequent localization of disease was hands (n: 105,%73 and %50.3 of patients had positivity with at least one allergen. The most frequent seven allergens with positivity were nickel sulfate (n: 50, %29.6, cobalt chloride (n: 23, %13.6, potassium dichromate (n: 22, %13, sesquiterpene lactone mix (n: 18, %10.7, thiuram (n: 10, %5.9, clioquinol mix (n: 10, %5.9 and 4-tert-butilfenol formaldehyde resin (n: 10, %5.9, respectively. On the other hand in all patients there were no positivity with N-Isopropyl-N-phenyl-4-phenylenediamine, epoxy resin, balsam of peru, formaldehyde, quaternium-15, primin, tixocortol-21-pivalate, fragrance mix-2. Conclusion: In comparison of this study which first reports patch test results of patients in Tekirdağ-a city in Trakya region and other studies that report patch test results of different regions of our country; the mean age of patients of present study were older and there were similar results for occupations and localization of disease in between eastern region and present study. We believe that further studies are needed to specify allergen characteristics of Trakya region using multicenter studies, which include other cities as well.

    Full Text Available The appropriate management of minor head injury (MHI in patients receiving oral anticoagulant (OAC is unclear. In this retrospective study, we focused on elderly patients (>65 years treated with OAC, presented to our emergency department with MHI between 2004 and 2010. Three hundred and six patients with MHI were taking OAC: we documented 7.19% hemorrhages at the first computed tomography (C; 18.19% deaths; 50.1% spontaneous reabsorptions; 22.73% deteriorations of intracranial bleeding without surgical intervention (for clinical comorbidity, and 4.55% neurosurgical interventions. We documented a second positive CT scan in 2 patients (1.51% who had no symptoms and remained asymptomatic during observation. In both cases, intracranial bleeding resolved spontaneously. The mean international normalized ratio (INR value was 2.26, higher in the group of patients with bleeding (2.74 than in the group without bleeding (2.19. We found a significant increased risk in patients with posttraumatic loss of consciousness [odds ratio (OR 28.3], diffuse headache (OR 14.79, vomiting (OR 14.2 and neurological signs (OR 5.27. We did not reach significance in patients with post-traumatic amnesia. Our data confirm the need for a CT scan of any patients on OAC with MHI. None of our patients developed any symptoms or signs during observation, and only 2 patients developed an intracranial hemorrhage in the second CT scan with a favorable evolution. Our data need to be confirmed with an observational study, but we suggest that the second CT could be reserved for patients developing symptoms and signs during observation. We also underline the role of the INR in the stratification of risk.

    2016-01-01

    Full Text Available Introduction: There is a gradual increasing trend in childhood cancers in India and pediatric palliative care in India is an emerging specialty. Prescribing pain and symptom control drugs in children with cancer requires knowledge of palliative care formulary, dosing schedules, and prescription guidelines. This study is a retrospective audit of prescribing practices of a specialist palliative care service situated in a tertiary cancer center. Methods: A total of 1135 medication records of children receiving specialist pediatric palliative care services were audited for 5 years (2010-2014 to evaluate prescribing practices in children with advanced cancer. Results: A total of 51 types of drugs were prescribed with an average of 4.2 drugs per prescription. 66.9% of the prescriptions had paracetamol, and 33.9% of the prescriptions had morphine. Most common nonsteroidal anti-inflammatory drugs prescribed was ibuprofen (23.9%, and more than 50% of the prescriptions had aperients. The most commonly prescribed aperient was a combination of liquid paraffin and sodium-picosulfate. Dexamethasone was prescribed in 51.9% of patients and in most cases this was part of oral chemotherapy regimen. Generic names in prescription were used only in 33% of cases, and adverse effects of the drugs were documented in only 9% of cases. In 25% of cases, noncompliance to the WHO prescription guidelines was seen, and patient compliance to prescription was seen in 40% of cases. Conclusions: Audit of the prescribing practices in specialist pediatric palliative care service shows that knowledge of pediatric palliative care formulary, rational drug use, dosing, and prescribing guidelines is essential for symptom control in children with advanced life-limiting illness. Noncompliance to WHO prescribing guidelines in one fourth of cases and using nongeneric names in two-thirds of prescription indicates poor prescribing practices and warrants prescriber education.

    Full Text Available BACKGROUND Human Immunodeficiency Virus (HIV infection is increasing at an alarming rate globally. Apart from heterosexual route, mother-to-child transmission is the next most important route of HIV transmission accounting for over 90% of infections in children. HIV infection in women occur primarily during their reproductive years, hence pregnancy provides a unique opportunity for implementing prevention strategies against HIV infection. OBJECTIVE The present retrospective study is undertaken to evaluate the effectiveness of implementation of PPTCT programme in SMGS Hospital, Jammu. MATERIAL AND METHODS All pregnant women attending antenatal OPD were counselled and tested for HIV. All positive patients were again counselled and ART started. Spouses of all positive women were counselled and tested. Universal work precautions, Modification of labour and delivery practices were followed. All the babies born to positive women received nevirapine prophylaxis for 6 wks and babies were tested at 18 months. Mothers were counselled regarding breast feeding. RESULTS A total of 22,047 ante-natal women were counselled and all of them gave consent for HIV testing. Seropositivity in these women was 0.09%. The no. of positive deliveries (54 exceeded the no. of positive antenatal cases (20. Most of these patients were primis or second gravidas, majority of them were young, belonging to age group of 20-30 yrs and most of them were not well educated; 100% of spouses were found to be seropositive. Most of these women (59.26% were delivered through vaginal route. LSCS was done for obstetric indication in 40.74% of cases. There were 100% live births. ALL the mothers opted for replacement feeding (100%. Seropositivity of babies born to these mothers could not be calculated due to loss of patients to follow-up. CONCLUSION The PPTCT programme is effective and has reduced the rate of transmission from mother to child. Labour room screening and early infant diagnosis

  5. Academic literacy diagnostic assessment in the first semester of first year at university

    Lorinda Palmer

    2014-03-01

    Full Text Available One vital aspect of the first semester of the first year at university is how academic literacy expectations are made explicit though teaching and assessment practices at the disciplinary level. This paper describes how an academic literacy diagnostic process, and the MASUS tool, was used to ascertain the academic literacy profile of a cohort of undergraduate nursing students [N=569] at the beginning and end of their first semester. Key findings of this quantitative descriptive case study were that only just over half of commencing students possessed appropriate academic literacy skills in all four aspects of the diagnostic and nearly 20% scored in the lowest band—suggesting difficulty with multiple aspects of academic literacy. By the end of semester, 77% of the students who had scored in the lowest band of the MASUS at the beginning of the semester had improved their scores to the middle or highest band, and 73% of them eventually attained a pass or higher grade for the course. The findings of this study suggest that large-scale academic literacy diagnostic assessment, when embedded and contextualized within a course of study, is an effective means of providing the early feedback and targeted support that many commencing university students need.

  6. Curriculum scholars: Embedding learning and teaching scholarship in first year academic identities. A Practice Report

    Peter Jones

    2011-07-01

    Full Text Available This practice report details an institutional innovation designed to enhance academic capacities for curriculum development, with a particular focus on the first year experience (FYE. The authors discuss the appointment of “Curriculum Scholars” in each of the faculties at James Cook University. This innovation can be seen as an example of third generation responses to the challenges of the first year in higher education (FYHE (Kift, Nelson & Clarke, 2010. The report  discusses the question of academic identity and the tension between a discipline-specific identity and identification with the scholarship of teaching and learning. The authors argue that this tension may have significant implications for the success of third generation approaches to the FYE. This tension is the focus of a multi-method research project being developed by the authors. The autoethnographical dimension of this project is described, inviting participants to reflect on their own journeys as academics engaged in learning and teaching.

  7. First year students negotiating professional and academic identities: The case of scholarly soldiers

    Kate Wilson

    2015-03-01

    Full Text Available As they make the transition to tertiary study, first year students adopt complex new identities. In professional courses, this entails both academic and professional identities. This paper reports on a study of the first year experience at UNSW Canberra (the Australian Defence Force Academy. UNSW Canberra aims to provide a quality liberal education for future military officers. With on-going military training and supervision, students develop a strong sense of professional identity as members of the Defence Forces. But what of their identity as scholars? This paper discusses the question of academic identity in an institution with a specific professional goal and reflects on the implications for learning advisers and lecturers in professional courses at other universities. Using a framework of social identity complexity, our findings suggest that students who manage these dual identities effectively are more likely to succeed than those who are unable to reconcile their professional and academic selves. 

  8. Profiling first-year students in STEM programs based on autonomous motivation and academic self-concept and relationship with academic achievement.

    Van Soom, Carolien; Donche, Vincent

    2014-01-01

    The low success rate of first-year college students in Science, Technology, Engineering, and Mathematics (STEM) programs has spurred many academic achievement studies in which explanatory factors are studied. In this study, we investigated from a person-oriented perspective whether different motivational and academic self-concept profiles could be discerned between male and female first-year college students in STEM and whether differences in early academic achievement were associated with these student groups. Data on autonomous motivation, academic self-concept, and early academic achievement of 1,400 first-year STEM college students were collected. Cluster analyses were used to distinguish motivational profiles based on the relative levels of autonomous motivation and academic self-concept for male and female students. Differences in early academic achievement of the various profiles were studied by means of ANCOVA. Four different motivational profiles were discerned based on the dimensions of autonomous motivation (A) and academic self-concept (S): students scoring high and respectively low on both dimensions (HA-HS or LA-LS), and students scoring high on one dimension and low on the other (HA-LS or LA-HS). Also gender differences were found in this study: male students with high levels of academic self-concept and autonomous motivation had higher academic achievement compared to male students with low levels on both motivational dimensions. For female students, motivational profiles were not associated with academic achievement. The findings partially confirm the internal and external validity of the motivational theories underpinning this study and extend the present insights on identifying subgroup(s) of at risk students in contemporary STEM programs at university level.

    Full Text Available Background/Aim. Necrotizing fasciitis (NF is usually an acute infection of superficial fascia with rapid progression in around soft tissue. If not promptly recognized and aggressively treated NF usualy leads to sepsis and multiorgan failure with fatal outcome, thus early diagnosis and prompt surgical treatment are crucial for healing of these patients. The aim of this article was to evaluate the clinical presentation of all patients with acute NF diagnosed and treated in surgical clinics of Clinical Center of Vojvodina, Novi Sad, Serbia. Methods. The medical records of patients treated for acute NF localized on a different parts of the body in Clinical Center of Vojvodina, Novi Sad, Serbia, during a 5- year period (from January 2008 to December 2012 were retrospectively evaluated. This study enrolled patients admitted via Emergency Center of Vojvodina with the diagnosis of acute NF either as the primary diagnosis or with the diagnosis at discharge after surgical treatment. Results. During a 5-year period there were 216 patients with final diagnosis of acute NF. Most of our patients (140 - 64.81% were admitted with the initial diagnosis of cellulitis, abscesses, phlegmons or sepsis. Unfortunately, the clinical symptoms of acute NF were atypical at time of initial examination. Pain and swelling of the affected localization were the most presented bias of symptoms (183 - 84.72%. The majority of our patients were male (164 - 75.92%. Among the 216 patients, the most common pre-existing single factor was drug abuse (39 - 18.05%, followed by obesity (38 - 17.59% and diabetes mellitus (31 - 14.35%. Trauma was most common etiological factor (22 - 10.8% in infected wounds, followed by abdominal (15 - 6.94% and orthopedic (11 - 5.09% surgical intervention. In the present study idiopathic acute NF was diagnosed in 22 (10.18% patients and more than one etiological factor were diagnosed in 20 (9.25% patients.

  1. Students' Persistence and Academic Success in a First-Year Professional Bachelor Program: The Influence of Students' Learning Strategies and Academic Motivation

    Gert Vanthournout

    2012-01-01

    Full Text Available The present study explores whether students' learning strategies and academic motivation predict persistence and academic success in the first year of higher education. Freshmen students in a professional bachelor program in teacher education were questioned on their learning strategy use and motivation at the start and at the end of the academic year. Students' learning strategies were assessed using the inventory of learning styles-SV. Motivation was measured using scales from the self-regulation questionnaire and the academic motivation scale. Gender and students' prior education were incorporated as control variables. Logistic regression analyses and general linear modelling were applied to predict persistence and academic success, respectively. In each case a stepwise approach in data analysis was used. Results on persistence indicate that lack of regulation and amotivation at the start of the year are significant predictors. For academic success, results showed that relating and structuring, lack of regulation, and lack of motivation at the end of the year are meaningful predictors. Overall, our study demonstrates that learning strategies and motivation have a moderate explanatory value regarding academic success and persistence, and that these effects remain even after controlling for the influence of background variables.

  3. Poor academic performance: A perspective of final year diagnostic radiography students

    Introduction: A study was conducted on final year diagnostic radiography students at a University of Technology in Durban. The aim of the study was to investigate the final year diagnostic radiography students' opinions and views on academic performance in order to inform teaching and learning methods. The objectives were: •To explore the students' opinions regarding poor performance. •To identify strategies to improve academic performance. Method: A qualitative, interpretive approach was used to explain and understand the students' lived experiences of their academic performances. A short open ended questionnaire was administered to a cohort of final diagnostic radiography students following feedback on a written assessment. Questionnaire responses were then manually captured and analyzed. Results: Five (5) themes were identified that could possibly be associated with poor academic performance. These themes were, poor preparation, lack of independent study, difficulty in understanding learning content and misinterpretation of assessment questions, inefficient studying techniques as well as perceived improvement strategies. Conclusion: Students identified their inadequate preparation and the lack of dedicated independent studying as the main reasons for poor performance. Students preferred to be taught in an assessment oriented manner. However their identified improvement strategies were aligned with the learner centred approach.

    Full Text Available The lips which constitute special anatomic structures, exposed in various irritant and traumatic factors, have increased danger to develop pathological lesions. A retrospective study of patients with squamous cell carcinomas of the lip commissure treated in the department of OMFS of the Cancer Hospital during the period 1995-2004 is presented.Thirteen such cases were studied and statistically analyzed,12 men and 1 woman. 8 farmers, a profession with intense exposure to the solar radiation. 10 patients presented with neck metastases, 3 at the time of initial examination, and 7 at a later point. 9 from the 10 patients were submitted to neck dissection, while 1 was not treated surgically due to lung metastases. The follow-up of the patients had an average of 49.23 months. Today six patients (46.17% are disease free, three(23.07% died from the disease and four (30.76% from other reasons. Patients with lip carcinomas of the commissure usually are found to be at advanced stages, which lead to wide excisions and complex reconstruction. In these patients a selective neck dissection should be performed for a N0 neck and a modified radical neck dissection for a N+ neck.

    2014-01-01

    Full Text Available Odontogenic tumors (OTs are lesions that develop exclusively on maxillary bones, and form a heterogeneous group. They vary from hamartomatous lesions to benign and malign tumors. Although they are rarely observed in dentistry clinics, it is extremely important for the dentist to be aware of them. The aim of this study was to investigate the incidence of odontogenic tumors diagnosed in the population of Florianópolis, Santa Catarina, Brazil. Cases of odontogenic tumors were selected from the anatomopathological diagnostic services at Federal University of Santa Catarina from 1998 to 2011. Clinical data on these cases were collected from biopsy reports and patient files. Seventy-eight cases of odontogenic tumors were surveyed. Of these diagnoses, 51% were keratocystic odontogenic tumors (KCOTs; the remaining cases were mainly ameloblastomas and odontomas. The most frequently observed lesion in this retrospective study was KCOT (more than half of cases. Thus, this study shows that modifying the classification of the OTs altered the frequency of the lesions, possibly making KCOT the most common lesion observed in diagnostic services worldwide.

  12. Histological review of skin cancers in African Albinos: a 10-year retrospective review

    Skin cancer is rare among Africans and albinism is an established risk for skin cancer in this population. Ultraviolet radiation is highest at the equator and African albinos living close to the equator have the highest risk of developing skin cancers. This was a retrospective study that involved histological review of all specimens with skin cancers from African albinos submitted to The Regional Dermatology Training Center in Moshi, Tanzania from 2002 to 2011. A total of 134 biopsies from 86 patients with a male to female ratio of 1:1 were reviewed. Head and neck was the commonest (n = 75, 56.0%) site affected by skin cancers. Squamous cell carcinoma (SCC) was more common than basal cell carcinoma (BCC) with a ratio of 1.2:1. Only one Acral lentiginous melanoma was reported. Majority (55.6%) of SCC were well differentiated while nodular BCC (75%) was the most common type of BCC. Squamous cell carcinoma is more common than basal cell carcinoma in African albinos

    2008-01-01

    The purpose of this retrospective study was to analyze the cases of traumatic dental injuries involving root fracture and/or periodontal ligament injury (except avulsion) treated at the Discipline of Integrated Clinic, School of Dentistry of Araçatuba, São Paulo State University (UNESP), Brazil, from January 1992 to December 2002. Clinical and radiographic records from 161 patients with 287 traumatized teeth that had sustained root fracture and/or injuries to the periodontal ligament were examined. The results of this survey revealed that subluxation (25.09%) was the most common type of periodontal ligament injury, followed by extrusive luxation (19.86%). There was a predominance of young male patients and most of them did not present systemic alterations. Among the etiologic factors, the most frequent causes were falls and bicycle accidents. Injuries on extraoral soft tissues were mostly laceration and abrasion, while gingival and lip mucosa lacerations prevailed on intraoral soft tissues injuries. Radiographically, the most common finding was an increase of the periodontal ligament space. The most commonly performed treatment was root canal therapy. Within the limits of this study, it can be concluded that traumatic dental injuries occur more frequently in young male individuals, due to falls and bicycle accidents. Subluxation was the most common type of periodontal ligament injury. Root canal therapy was the type of treatment most commonly planned and performed. PMID:18949308

    2016-05-01

    To better understand the changing toxicology trends in suicidal drug overdoses in the setting of an increased national trend of multidrug overdoses, a retrospective review of electronic records from New Mexico's Office of the Medical Investigator database was performed between 2008 and 2012 to assess the drug type and current risk factors in suicide deaths. Information on demographics, circumstances, suicide risk factors, toxicology findings, and death certificates was collected and analyzed. Three hundred and forty-two suicide cases of suicide overdoses were identified. Decedents were predominantly female (61.8%). Scene investigation revealed risk factors including suicide ideation (47.4%), previous suicide attempts (38%), and suicide note (38%). Psychiatric illness was present in 72% of cases, with depression being the most common illness. Chronic pain was seen in 27.2% of cases. Most deaths were attributed to multiple drugs (76%). Utilizing the toxicology information will assist in creating public awareness and provide a framework to support targeted efforts to attempt to prevent future suicides. PMID:27122402

    Full Text Available Background: Developing countries at tertiary referral centre. This study analysed the aetiology of colonic perforation (CP in neonates and infants. Materials and Methods: Retrospective analyses of 60 CP cases (presented from May 2005 to May 2011 were done. Results: The mean age at presentation was 8.33 ± 0.11 days (range, 2-110 days. The aetiology were Hirschsprung′s disease (HD, necrotising enterocolitis (NEC and idiopathic perforation in 78.33% (47/60, 6.67% (4/60 and 15% (9/60, respectively. There were 210 patients with histopathologically proven HD; 22.38% (47/210 cases of HD had CP. Most common site of perforation was mid-transverse colon (74%, 35/47 in HD patients. All HD-associated mid-transverse colonic, caecal, appendicular and ascending colon perforations (except one caecal perforation had aganglionic recto-sigmoid region and ganglionic perforation site. Features of enterocolitis were not found in any HD patients. Two patients (3.33% died due to sepsis. Conclusions: There was a high rate of primary HD-associated colonic perforation in this study. Colonic perforation may the initial presenting condition in HD disease. We advocate colonic biopsy to rule out HD in any neonate presenting with primary colonic perforation.

  16. A ten year retrospective series of ulnar dysplasia: clinical presentation and treatment results

    The ulnar deficiency is an alteration in the embryological development of the ulnar side of the forearm and the hand. The deformities affect hand, wrist and elbows; only 11% of the patients had complete fingers and 38% of the cases had syndactyly. Objective. Described the epidemiological profile and the clinical and radiological features and the results of treatment in 14 children. Materials and methods. It is a descriptive study type series of cases, retrospective in 14 children (18 upper extremities). The clinical and radiological characteristics were evaluated. Results. The bilateral compromise was 28.5%. The types II and IV of Bayne were the predominant with a 66.5%. The multiple surgeries were 41%. Functionally it was not possible to homogenize an instrument pre and postoperative. The grip improves of lateral to bidigital or tridigital in 72.2% of the patients, an indicator of a progress significant functional. The 84% presented good global grip and improvement in the daily basic activities. Conclusions. A classification that can integrate the diversity of anomalies doesn't exist. The classification of Bayne includes to a great quantity of them but there are some difficult of classifying as some cases with similarity to transverse deficiencies of the forearm. The treatment is specific for each case in particular. We know that the compromises of the elbow and of the first metacarpal are crucial in the functional result. The improvement of the clip was achieved in 72.2% of the cases were taking to surgery.

    The objective of this study is to assess different outcomes between endoscopic dacryocystorhinostomy (En-DCR) with and without silicone intubation. We retrospectively analyzed 84 patients (89 procedures), suffering from chronic epiphora for primary acquired nasolacrimal duct obstruction, treated with En-DCR and divided into two groups depending on silicone stent intubation. The surgical outcomes were evaluated at 7 post-operative controls using Munk's score criteria. Functional success was defined as absence of epiphora, no further episodes of dacryocystitis, and a patent ostium after fluorescein irrigation. 45 En-DCR with stent and 44 En-DCR without stent were performed. Success rate after 18 months follow-up were, respectively, 82.2 % in the stent group and 88.6 % in the non-stent group (OR 0.59) with no statistical differences. The ostial size reduction has been reported in higher percentage in the stent group, mainly due to peristomal granuloma (OR 3.64), scar tissue formation (OR 2.25), and turbinoseptal synaechia (OR 1.76). The benefits of non-intubation are less patient discomfort, reduced surgical time and costs, simpler follow-up regimen and less intubation-associated complications. En-DCR without silicone stent intubation should be the first choice of procedure, stent intubation should be reserved in selected cases with poor local conditions pre and intra-operatively assessed.

    The purpose of this paper is to describe a series of patients who have undergone medialisation thyroplasty (with or without arytenoid adduction) at our centre with respect to demographics, aetiology for unilateral vocal fold paralysis, pre- and postoperative maximum phonation time, amount of anterior and posterior medialisation required and complications. A comparative analysis with international studies was also performed. A retrospective analysis was performed on 67 patients, who underwent medialisation thyroplasty at our centre from August 2008 to August 2014. All the medialisation thyroplasty were performed using Netterville's technique. The average anterior medialisation needed was 2.25 mm (SD 1.05 mm) while the average posterior medialisation needed was 6.75 mm (SD 1.79 mm). Our study is the first to determine the amount of anterior and posterior medialisation needed in the Indian population. Mean anterior and posterior medialisation required was found to be the same, regardless of the age, gender of the patient and side of surgery. PMID:27002319

  19. Uranium resources production and demand: a forty years evaluation 'Red book retrospective'

    Uranium Resources, Production and Demand, also familiarly known as the ''Red Book'' is a biennial publication produced jointly by the NEA and the IAEA under the auspices of the joint NEA/IAEA Uranium Group. The first edition was published in 1965. The red book retrospective was undertaken to collect, analyse and publish all of the key information collected in the 20 editions of the Red Book published between 1965 and 2004. The red book gives a full historical profile of the world uranium industry in the areas of exploration, resources, reactor-related requirements, inventories and price. It provides in depth information relating to the histories of the major uranium producing countries. Thus for the first time a comprehensive look at annual and cumulative production and demand of uranium since the inception of the atomic age is possible. Expert analysis provide fresh insights into important aspects of the industry including the cost of discovery, resources to production ratios and the time to reach production after discovery.

    Full Text Available : In inguinal hernia tension free hernioplasty using polypropylene mesh by Lichenstein and Schulman’s method is accepted all over the world. But cost of the mesh is a major contributor to the cost of repair in rural India. A retrospective study of 105 Inguinal hernia operated patients from 1st March 2007 to 30th October 2011 was undertaken to evaluate efficacy and cost benefit of Mosquito Net Mesh (MNM as against conventional mesh repair. All patients were operated under spinal anaesthesia. The ETO sterilized MNM of size 7.5cm by 13cm was used for repair. The incidence of complications, recurrence and cost benefit was investigated after a mean follow up of 37 months. The rate of seroma formation (n=0, hematoma formation (n=0, superficial infection in the form of erythema (n=3, serous discharge after stitch removal (n=7, chronic pain (n=4 and recurrence (n=2 were low. The cost benefit was 40% - 50% of the total cost of the repair by using MNM. ETO sterilized MNM forms a cheap, safe and efficient alternative to the conventional and costly polypropylene mesh in open tension free repair of inguinal hernia in adults.

    2009-06-01

    Full Text Available The main options for the treatment of wrist ganglia are reassurance, aspiration, arthroscopic resection and open excision. Variations within each option have been described and the literature is clouded by widespread variability in the results reported. We present the results of our own long-term retrospective study, review the literature and question the surgical risks and demands placed on healthcare resources. A retrospective review of the surgical results of dorsal and volar wrist ganglia excision between January 1998 and March 2005 was undertaken at a single institution. Of the 152 patients in this consecutive series, 117 (77% patients responded to a telephone questionnaire. The mean length of follow-up in this series of 117 patients was 4.2 years (range 1.5-8.7 years. The overall recurrence rate following excision of all wrist ganglia in this series was 41.8 %. When looking just at volar ganglia, the risk of recurrence is higher at 46.8%. Should the ganglion recur, the risk of developing a moderate to severely tender scar is 34.6% and the risk of developing an unsightly scar is 8.2%. This study questions the effectiveness of surgical excision in the treatment of wrist ganglia when performed by a mixture of surgeons in that the recurrence rates are very similar to the rates seen in studies that merely observe or aspirate wrist ganglia. We propose that for symptomatic ganglia, specialists in hand surgery may be more appropriate at treating such a pathology.

    Full Text Available Background: Intracranial lesions of the pituitary gland are common pituitary adenomas, accounting for 6-10% of all symptomatic intracranial tumors. In this retrospective study, the clinicopathologic features and survival rate of pituitary adenomas were evaluated.Methods: The present retrospective study was conducted on 83 patients with pituitary adenomas, referring to radiation oncology departments of Ghaem and Omid Hospitals, Mashhad, Iran, over a period of 13 years (1999-2012. Data obtained from clinical records including clinical features, type of surgery (if performed, treatment modality, overall survival rate, and progression-free survival rate were analyzed.Results: Eighty-three patients including 44 males (53% and 39 females (47% participated in this study. The median age was 40 years (age range: 10-69 years. Chiasm compression was reported in 62 patients (74.4%, and 45.78% of the subjects suffered from headaches. Functional and non-functional adenomas were reported in 44 (53.01% and 39 (46.99% patients, respectively. In cases with functional and non-functional adenomas, the disease was controlled in 95 and 84.5% of the subjects for 3 years, respectively. Furthermore, 1- and 3-year survival rates for functional adenoma were 84.6 and 23%, respectively; the corresponding values were 90.9 and 22.7% in non-functional adenomas, respectively.Conclusion: In this study, a significant correlation between headache severity and type of adenoma was observed. So, application of surgery and radiotherapy together could be a highly effective approach for treating functional adenomas, although it is less efficient for the non-functional type.

    Medgar Evers College, City University of New York, has initiated a multi-tiered strategy aimed at increasing the number of under-represented minority and female students pursuing careers in the Geosciences, especially Earth and Atmospheric Sciences and related areas. The strategy incorporates research on the persistence of minority and female under-represented students in STEM disciplines. The initiatives include NASA and NSF-funded team-based undergraduate research activities during the summer and academic year as well as academic support (clustering, PTLT workshops for gatekeeper courses), curriculum integration modules, and independent study/special topics courses. In addition, high school students are integrated into summer research activities working with undergraduate and graduate students as well as faculty and other scientist mentors. An important initial component was the building of an infrastructure to support remote sensing, supported by NASA. A range of academic year and summer research experiences are provided to capture student interest in the geosciences. NYC-based research activities include urban impacts of global climate change, the urban heat island, ocean turbulence and general circulation models, and space weather: magnetic rope structure, solar flares and CMEs. Field-based investigations include atmospheric observations using BalloonSat sounding vehicles, observations of tropospheric ozone using ozonesondes, and investigations of the ionosphere using a CubeSat.

    Full Text Available Background: Androgen insensitivity syndrome (AIS or testicular feminization is a partial or complete inability of cell response to androgen. The cause is enzymatic defect in synthesis of testosterone, resulting sexually immature phenotypically female, with primary amenorrhea. There are three categories of AIS, complete, partial and mild, depending on the degree of external genital masculinization. The aim of this study was to find out chromosomal abnormalities, and correlation between AIS and maternal/paternal age, parents' consanguineous marriage, family history and clinical observation, in Iranian AIS patients.  Method: This study includes a retrospective data analysis of 72,000 families' medical records in the Genetic Clinic in Tehran, during a 30-yr period (1984-2014. The essential basis for the patients' referral to the clinic by gynecologists was primary amenorrhea. Cytogenetic abnormalities has been confirmed by chromosome G-banding and conventional staining methods.Results: Seventy AIS female patients with 46XY pattern were cytogenetically diagnosed and the frequency of AIS syndrome was estimated about 0.05% (~70/140000. The results showed no association between AIS and maternal or paternal age nor were the marital pattern of the parents. The clinical findings illustrated that primary amenorrhea had the highest indication for referral of AIS patients for genetic counseling and cytogenetic study.Conclusion: No correlation was observed between AIS and maternal or paternal age or consanguineous marriages. Amenorrhea is the most clinically observed sign of AIS patients.  Keywords: Androgen insensitivity syndrome (AIS, Testicular feminization, Human androgen receptor (HAR, Amenorrhea, Iran

    Full Text Available BACKGROUND: Mother to child transmission of HIV is a major cause of paediatric HIV. MTCT prevention strategies include comprehensive antenatal, postnatal and paediatric health services, voluntary counselling and testing (VCT, antiretroviral prophylaxis; counselling and support for safe infant feeding and optimal obstetrical practices. OBJECTIVES: The present retrospective study is undertaken to evaluate the effectiveness of implementation of PPTCT Programme in a tertiary care hospital. METHODOLOGY: All pregnant women attending antenatal OP and labour room were counselled and tested for HIV. All positive patients were again counselled and ART therapy started. Spouses of all positive women counselled and tested. Modification of labour and delivery practices was followed . All the babies born to positive mothers received Nevirapine prophylaxis and babies were tested at 6, 12 and 18 months. Mothers were counselled regarding breast feeding and tubectomy was advised for all patients. RESULTS: A total number of 36113 antenatal women counselled and 97.90% of them gave consent for testing. Seropositivity in these women was 0.91%. Most of these patients were primi or second gravida, majority of them were young, belonging to age group of 20 - 24 yrs. 61.84% of spouses were found to b e seropositive. Most of these women (67.72% were delivered through vaginal route. LSCS was done for obstetric indication in 32.27% of cases. Majority of mothers opted for replacement feeding (78.96%. Seropositivity of babies born to these mothers was 3.0 7%.This has shown downward trend from 2010 to 2015.

    Rossana Perez del Aguila

    2014-12-01

    Full Text Available ABSTRACT: This article presents the findings of an action research project carried out in 2012 with 12 first-year university students taking ‘Education Studies’ in a university in England. The aim of the project was to explore the best ways to support students’ academic writing skills. The literature review highlights the challenges students encounter when trying to learn the discourse of adiscipline; and in the light of this examination, a reflection on the strengths and weaknesses of my own practice provides the context for carrying out an action research project. The teaching intervention was assessed using the following methods of data collection: questionnaires and semi-structured interviews with students, and content analysis of my own feedback on student’s final assignments. The outcomes of the research demonstrate that students’ difficulties with their academic writing are related to their struggle to understand specialized concepts, theories and methods of the discipline.

  20. A participative evaluation model to refine academic support for first year Indigenous higher education students

    Bronwyn Rossingh

    2012-03-01

    Full Text Available This paper presents an evaluative approach designed to provide a cycle of continuous improvement to retain Indigenous students during their first year of higher education.   The evaluation model operates in conjunction with a student academic enrichment program that is premised on valuing and respecting each student's background and life experience whilst building capability for learning success.  Data collected will be used for continual improvement of a newly developed innovative academic enrichment program that caters to the needs of Indigenous students.  The defining mechanisms of the model for measuring the first year experience are particularly meaningful for the Australian Centre For Indigenous Knowledges and Education as it moves into its inaugural year of operation in 2012. This preeminent time requires a flexible model to receive timely feedback in a reflexive environment where students guide the process as they continue their journey of accumulating knowledge and leave behind their contribution in shaping the landscape for future first year Indigenous students.  

  1. DEVELOPMENT OF THE INFORMATION COMPETENCE OF THE ACADEMIC COMMUNITY: TWENTY YEARS AFTER

    Glosiene, Audrone

    2006-12-01

    Full Text Available Twenty years ago, reading culture, library skills’ development used to be one of the core directions in research and teaching policy of the Department of Library Science at Vilnius University. Lateron, the topic was marginalized and today we return to the field that meanwhile has developed huge knowledge and experience base worldwide. A stimulus for the return was participation in BIBLIONOVA project. The aim of the article is to present a holistic approach towards information competency development in a modern academic institution. Prescriptive approach based on information literacy standards proved to be limited and not always effective in the academic environment.Information competency development is problem-specific, domain-specific, and disciplinespecific. It is interrelated with critical thinking, analytical skills as well as creativity and computerliteracy skills. Holistically, information competency development is an integral part of university’s life-long learning strategy. Critical success factors for information competency development areopen and problem-based learning and cooperative, inclusive strategies of the whole university. Academic libraries continue to play a major role in the process but the connections with faculty and administration in the process are of major importance.

    2014-03-01

    Full Text Available Statement of Problem: Information about etiology and incidence of maxillofacial trauma is important for prevention and appropriate treatments of such injuries. Purpose: The purpose of this retrospective study was to conduct an analysis of maxillofacial injuries transferred and/or referred to the department of maxillofacial Surgery at Chamran emergency hospital, Shiraz, over a 6-year-period with special reference to age, gender, occupation, date, type, site, etiology and clinical management. Materials and Method: The data for this study were collected and reviewed retrospec-tively from the records and radiographs of 768 patients who were treated for maxillofacial trauma in the department of maxillofacial surgery at the Shiraz Chamran Emergency Hospital, Iran, between 2004 and 2010. Results: A total of 730 of the subjects were the patients with fractures of the facial skeleton. The mean age was 26.6± 12.6 years, ranging from 2 to 81 years. Traffic accident was the most frequent etiological factor of maxillofacial fractures irrespective of gender (69.9% for men and 54.2% for women, whereas the second most frequent cause of injuries was falling down (9.8% for men and 21.5% for women .The other etiologies were assault (5.2%, sport related injuries (1.3% and firearm injuries (1%. Regarding the head injuries in patients with maxillofacial fractures, brain contusion was seen in 227(29.6% patients and 13.5% of patients had lacerations in the facial soft tissue. The monthly distribution peaked in October, with 81 cases (10.5%, which seems to have been due to schools opening. The next highest incidence was in December, with 80 cases (10.4%, probably because of the changing weather's effect on road traffic. Conclusion: Isolated mandibular fracture due to the road traffic accident was the most common type of maxillofacial injuries in the city of Shiraz.

  4. Characterizing learning-through-service students in engineering by gender and academic year

    Carberry, Adam Robert

    Service is increasingly being viewed as an integral part of education nationwide. Service-based courses and programs are growing in popularity as opportunities for students to learn and experience their discipline. Widespread adoption of learning-through-service (LTS) in engineering is stymied by a lack of a body of rigorous research supporting the effectiveness of these experiences. In this study, I examine learning-through-service through a nationwide survey of engineering undergraduate and graduate students participating in a variety of LTS experiences. Students (N = 322) participating in some form of service -- service-learning courses or extra-curricular service programs -- from eighty-seven different institutions across the United States completed a survey measuring demographic information (institution, gender, academic year, age, major, and grade point average), self-perceived sources of learning (service and traditional coursework), engineering epistemological beliefs, personality traits, and self-concepts (self-efficacy, motivation, expectancy, and anxiety) toward engineering design. Responses to the survey were used to characterize engineering LTS students and identify differences in these variables in terms of gender and academic year. The overall findings were that LTS students perceived their service experience to be a beneficial source for learning professional skills and, to a lesser degree, technical skills, held moderately sophisticated engineering epistemological beliefs, and were generally outgoing, compassionate, and adventurous. Self-perceived sources of learning, epistemological beliefs, and personality traits were shown to be poor predictors of student engineering achievement. Self-efficacy, motivation, and outcome expectancy toward engineering design were generally high for all LTS students; most possessed rather low anxiety levels toward engineering design. These trends were generally consistent between genders and across the five academic

    Full Text Available Assisted reproductive technology (ART has grown by leaps and bounds in the last few years. India has one of the highest growths in the ART centers and the number of ART cycles performed every year. Very soon India will be the leader in the world of ART in terms of a number of cycles. With the advances of technology and availability of techniques even in tier II and tier III cities our country, the results still vary dramatically. There is no standardization of protocols and reporting is very inadequate. Furthermore, there are only ART guidelines and no law still exists. Our first and the biggest challenge is to document the tremendous work being done in India and on the basis of analysis of this work, a proper registry can be made and guidance given to all on standardization and improvement. This is the 8 th edition of National ART Registry of India being presented and analyzed.

In thesecond group compassing the period from the second halftermof the year 2006 to the end of the year 2011, ovariancancers were again the most frequently seen gynecologicalcancers. On the other hand it was found that there was anincrease in the percentage of endometrial cancers. Whilecases with advanced staged constituting the major part ofthe patients with ovarian cancer, it was seen that the majorityof the patients with endometrium cancer were consistingof stage 1 cases. In the 4 of 6 cases having endometriumcancer and applying with the complaint of pain, the diseasewas noticed in the advanced stage. Being the most frequentlyseen gynecological cancer all over the world andespecially in the societies with lower socio-economic status,the cervix cancer was taking place in the 3rd order afterendometrium cancer in terms of frequency in our region.Conclusion: Consequently, in the recent years the gynecologicalcancer showing the most frequent increase wasendometrium cancer in our region. The increase in the frequencyof obesity, relating with the reasons like the impropernutrition behavior, the increase in the socio-economic status,may be associated with the increase in the frequencyof endometrium cancer.

  18. Paediatric parotid neoplasms: a 10 year retrospective imaging and pathology review of these rare tumours

    Aim: To determine the relative incidence of benign and malignant paediatric parotid gland tumours and whether particular presenting symptoms or imaging characteristics were more likely to predict malignancy. Materials and methods: Hospital records were reviewed for all patients <18 years with histopathology-proven parotid neoplasms over the 10 year period from 2003–2013. Infantile haemangiomas and patients with neurofibromatosis type I were excluded. The presenting clinical symptoms for each patient were recorded. All available CT and MRI examinations for these patients were evaluated for tumour imaging characteristics. Results: Seventeen patients (nine boys, eight girls; age range 2–17 years) were identified with neoplastic parotid masses; 11 tumours were malignant (65%) and six were benign (35%). The malignant tumours consisted of three acinic cell carcinomas, two mucoepidermoid carcinomas, one alveolar rhabdomyosarcoma, one poorly differentiated carcinoma, one low-grade adenocarcinoma, and three metastases (two melanoma, one orbital medulloepithelioma). The benign tumours consisted of five pleomorphic adenomas and one schwannoma. Presenting clinical symptoms were similar between benign and malignant tumours. Twelve MRI and six CT examinations were available for review with five patients undergoing both techniques. MRI features commonly identified with malignant tumours included: hypointense T2 signal, restricted diffusion, ill-defined borders, and focal necrosis. Only four of the six tumours imaged at CT were visualized, and of those, the margins were indeterminate in three patients. Conclusion: Paediatric parotid masses are more likely to be malignant than benign. Presenting clinical symptoms and CT are not helpful for distinguishing benign and malignant disease. MRI features such as T2 hypointensity, restricted diffusion, ill-defined borders, and focal necrosis, although not specific, should raise concern for malignancy. - Highlights: • Pediatric parotid

    Full Text Available Silicosis is a form of pneumoconiosis. It results from inhalation of dust containing crystalline Silica particles of size 0.5 - 5 microns in diameter. Prevalence of Pulmonary Tuberculosis in Silicotics is more common when compared to prevalence in general population. This entity is called Silico-tuberculosis. Study was conducted in Kamla Nehru Chest Hospital attached with Dr.SNMC Jodhpur, among 300 stone mine workers of sand stone mines of Jodhpur with clinico-radiological evidence of Silico-tuberculosis. Workers were divided into 3 categories cutter / driller involved in blasting and cutting stones, dresser engaged in fine work by chisel and Labourer - Loading and Unloading of Stones in Mines .All studied patients were males, majority of cases belong to 21-55 years (93% age group. Among these cases maximum no. of patients belong to 46-50 yr. (18% age group. This is the most economically productive age group in India. With increase in duration of exposure from (0-20 years to Silica particles there is increase in the no. of silico-tuberculosis.

    Comparison of the state of 83 patients with histologically confirmed sarcoidosis observed with a 10 year interval revealed remission in 47% of the cases. The main factors having negative effect on prognosis of the disease included extrapulmonary symptoms, the use ofcorticosteroids (at all stages, especially at stage I and in Lofgren syndrome) and antituberculosis drugs, positive TB test. Risk factors of relapses were stage II sarcoidosis, the use of systemic corticosteroids in patients with Lofgren syndrome and antituberculosis drugs, initially low FEV1/FVLC ratio and the number of lymphocytes in peripheral blood.

    Full Text Available Objective: This study aims to evaluate and compare with the existing literature on the etiology, pattern, gender, and anatomical distribution of mandibular fractures. Materials and Methods: The data of 225 cases were analyzed over a period of 5 years between March 2009 and November 2013. Of this 110 were unilateral, 23 bilateral, 18 symphysis and 74 multiple fractures. Results: Males are more affected than females.The peak incidence rate is occurring in 30-35 years of age group. The most common fracture site is parasymphysis and least common site is ramus of mandible. The most common etiological factor is road traffic accident (RTA (45.3% followed by falls (42.6%, assaults (8.9%, sport injuries (2.2%, and gunshot wounds (0.89%. Conclusion: Thus, we conclude that RTA is the leading cause of mandibular fractures and males are more affected. The most common site is parasymphysis fracture in association with angle fracture. We observed that gender was significantly associated with body and angle fracture (P = 0.04 and significant relationship between etiology with multiple site fracture such as (parasymphysis-angle, (body-condyle, (body-angle, and (symphysis-condyle was observed (P ≤ 0.05.

  2. Edgar G. Ulmer’s Film The Black Cat: An Eighty-Year Retrospective

    Ronald Duke Saltinski

    2014-08-01

    Full Text Available Director Edgar G. Ulmer’s film The Black Cat was a rare achievement in American horror cinema when released in 1934. Some eighty years afterwards in 2014 The Black Cat warrants revisiting as one of the most unique and revered horror films ever made. The Black Cat is German expressionist in character, perverse and morbid, portraying the post World War I gothic mind of Europe. The film encompasses the rage and revenge of that war with motifs of murder, narcotics, torture, necrophilia, incest, and Satanic rituals; all of which are witnessed by a young America couple who have innocently traveled into a nightmarish tragedy. Rarely has a film like The Black Cat so captured the mood of horror blended with an intellectual narrative, unique acting, modernist settings, and classical music. Paul A. Cantor said “The Black Cat was a triumph for Ulmer; many consider it one of the most sophisticated and powerful horror stories ever made” (p. 142. Years later The Black Cat would be characterized as an “art film,” and even “read as a piece of intellectual cinema” (Schwaab, p. 46.

  3. A Ten Year Retrospective on Environmental Justice: What Have We Learned?

    Beginning in 1994, Executive Order 12898 has directed federal executive agencies to identify and address, as appropriate, disproportionately high and adverse health or environmental effects of their programs, policies, and activities on minority and low income populations. The policy behind the Executive Order was to prevent minority and low income groups from bearing disproportionate adverse environmental consequences of federal actions. During the last ten years, federal agencies have implemented Executive Order 12898, and some also have developed explicit procedures or guidance for the steps that need to be taken during the preparation of environmental impact statements. Based on the authors experience, the paper examines how environmental justice practice has evolved in the ten years since the original Executive Order was issued. This evolution has been both procedural and substantive. The paper examines how the actual practice of environmental justice analysis has progressed in federal agencies that deal with waste management issues. Reference is made to changes in case law and agency practice. The 2000 Census of Population and the ongoing development of geographic information systems in particular have made it easier to identify minority and low-income populations at risk. At the same time, a number of stakeholder groups have taken positions over specific federal actions that have given rise to novel issues and challenges for analysts. The paper discusses how NEPA practice is evolving to deal with these issues and challenges

  4. Viral infections, prevalence and costs: A5-year, hospital based, retrospective observational study in shiraz, iran

    Many patients suffering from viral infections attend to health care centers. Data gathered from viral infections is limited to specific cases such as AIDS, viral hepatitis and Influenza. There is a significant lack of reliable documentation about other viral infections. In this study the prevalence and related costs of viral infections in hospitals of Shiraz University of Medical Sciences were reviewed. In this cross-sectional study the data were extracted from files of 1319 patients with viral infection admitted in two university hospitals during a five year period (1999-2004). The frequencies of different viral infections along with their demographic data were analyzed. The mean age of the patients was 29.24 with the range of 90 years. Hospitalization days were 8636 in 40 different wards in two hospitals. US$ 30.84 was the daily mean cost for each admitted patient. Viral meningitis was most frequent (14.2%) and 8.4% of patients died during hospitalization. This study confirms the necessity of expanding management programs for viral infections especially hepatitis B in youths in Iran. Unspecified viral infections cost much more than specified viral diseases. Viral infection costs can be reduced by finding more sensitive and specific diagnostic methods. (author)

  5. Ten-Year Retrospective Longitudinal-Study of Student Perspectives on Value of REU

    Slater, T. F.; Slater, S. J.

    2013-12-01

    For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational

The paper highlights novel aspects of the Bailly facility, including pulverized limestone injection, air rotary sparger for oxidation, wastewater evaporation system and the production of PowerChip{reg_sign} gypsum. Operations and maintenance which have led to the facility`s notable 99.47% availability record are also discussed. A project company, Pure Air on the Lake Limited Partnership, owns the AFGD facility. Pure Air was the turn key contractor and Air Products and Chemicals, Inc. is the operator of the AFGD system.

  7. Fluorine in medicinal chemistry: a century of progress and a 60-year retrospective of selected highlights.

    Filler, Robert; Saha, Rituparna

    2009-08-01

    This perspective explores the origins of both fluorine and medicinal chemistry a century ago and traces the early history of the intersection of these areas and the subsequent roles that fluorine has played in advancing medicinal innovations and diagnoses during the past 60 years. The overview highlights remarkable breakthroughs in many diverse areas of medicinal chemistry, including inter alia, anesthetics, steroidal and nonsteroidal anti-inflammatory drugs, anticancer and antiviral agents, CNS medications, antibacterials and cholesterol biosynthesis inhibitors. The increasing use of fluorine-18-labeled radiotracers in PET for diagnostic imaging of the brain, heart and in oncology is briefly presented. The signature roles of fluorine in medicinal chemistry are now firmly established. The presence of fluorine in pharmaceuticals has had a major impact on a plethora of important medical applications, such as those cited above. Fluorine will very likely continue to contribute significantly by playing multifaceted roles in enhancing future medical advances. PMID:21426080

  8. THE CARTEL IN THE EUROPEAN UNION AND ROMANIA - RETROSPECTIVE OF THE YEARS 2009-2013

    Berinde Mihai

    2014-07-01

    Full Text Available The cartel is considered the most harmful anti-competitive practice; therefore the competition authorities were concerned about the continuous improvement of the legislation governing this practice. In order to stimulate companies to withdraw from participating to a cartel in the European Union, the leniency policy has implemented. The present paper aims at achieving the hindsight of the years 2009-2013 regarding the evolution of cartel cases detected both at EU level and in Romania. The research methodology used is the study of literature, followed by the analysis of the legislation governing the European cartel and the analysis of all decisions issued between 2009-2013, both by the European Commission and by the Competition Council of Romania. The paper is structured in four parts. The first part presents the cartel from the theoretical and legislative point of view. The second and third parts of the paper include the analysis of cartel cases detected both at European and national level. The following aspects were taken into account when analysing the cartel cases: the date when the decision was issued by the competition authorities, the number of companies involved in the cartel, the opening date of the investigation, the method of opening the investigation, the field in which the cartel operated, the duration of the cartel as well as the amount of the fine. The final part of the paper highlights a number of conclusions. In the reviewed period 22 cartel cases were detected in the European Union and 23 cartel cases in Romania. The amount of the fines imposed at a European level is 251 times higher than the fines imposed by the Competition Council of Romania. In the European Union there were 11 long-term cartel cases, 10 medium-term cases and only one case lasted less than a year. In Romania there have been detected 4 long term cartel cases, 7 medium-term cases and 12 cases of short-term cases.

    Full Text Available Pemphigus is an autoimmune blistering disease of the skin and mucous membranes with different reported epidemiological aspects from different countries. Aim: Our aim was to evaluate the epidemiological aspects of pemphigus in Mashhad city. This is the first report with regard to the characteristics of pemphigus in Khorasan province of Iran. Materials and Methods: In this cross-sectional study, all the patients with pemphigus, who were referred to the Dermatology Department of Imam Reza hospital of Mashhad, were examined over nine years, i.e., from May 1998 to March 2007. The data obtained through questionnaires, including age, sex, profession, mucosal or skin or the involvement of both, lag-time period between the onset of disease and the first presentation, gap between cutaneous and mucosal involvements, season of onset and family history, were analysed by using statistical tests of Chi square and Student′s t -test and the statistical software of SPSS. Results: In 178 patients with pemphigus, pemphigus vulgaris was the most common type (86.5%. Female to male ratio was 1.4. In pemphigus vulgaris patients, there was involvement of both the skin and mucosa in 64.3%, mucosal involvement in 14% and skin involvement in 21.7%. There was no mucosal involvement in patients with pemphigus foliaceus. Two patients (1.4% had a positive family history. Summer was the most common season for the onset of the disease (37.5%. Most of the patients were housewives in the premenopausal age group. Conclusion: The results reveal a high incidence of pemphigus in northeast Iran with an incidence of 20 patients per year.

  10. First year Business students’ perceptions of academic support through embedding. A Practice Report

    Carmela De Maio

    2016-03-01

    Full Text Available This paper explores the perceptions of first year Business students to embedding sessions and additional support workshops offered through a collaboration between learning advisors and lecturers in a first year foundational unit. Through a social constructivist lens and utilising action research methods, questionnaires (n=42 were administered to two cohorts of students at the conclusion of the unit in 2011 and 2012 to explore firstly, whether or not they perceived the embedding sessions to be of benefit and, secondly, whether having the learning advisor in the class made them more likely to utilise additional support outside class time. In addition, the researchers sought to explore whether there were any improvements in students’ final results which might be attributable to the academic support offered to them through the embedding sessions. The findings from the quantitative and qualitative data suggest that the students perceived the embedding workshops as having positive effects on their academic literacy skills.  Furthermore, there was a slight increase in the number of students that sought additional support outside of class time.  However, it appears that the embedding workshops did not lead to an improvement in students’ final marks for the unit and this is an area which requires further investigation.

  11. Protein-tyrosine phosphorylation in Bacillus subtilis: a 10-year retrospective

    Josef eDeutscher

    2015-01-01

    Full Text Available The discovery of tyrosine-phosphorylated proteins in Bacillus subtilis in the year 2003 was followed by a decade of intensive research activity. Here we provide an overview of the lessons learned in that period. While the number of characterized kinases and phosphatases involved in reversible protein-tyrosine phosphorylation in B. subtilis has remained essentially unchanged, the number of proteins known to be targeted by this post-translational modification has increased dramatically. This is mainly due to phosphoproteomics and interactomics studies, which were instrumental in identifying new tyrosine-phosphorylated proteins. Despite their structural similarity, the two B. subtilis protein-tyrosine kinases (BY-kinases, PtkA and PtkB (EpsB, seem to accomplish different functions in the cell. The PtkB is encoded by a large operon involved in exopolysaccharide production, and its main role appears to be the control of this process. The PtkA seems to have a more complex role; it phosphorylates and regulates a large number of proteins involved in the DNA, fatty acid and carbon metabolism and engages in physical interaction with other types of kinases (Ser/Thr kinases, leading to mutual phosphorylation. PtkA also seems to respond to several activator proteins, which direct its activity towards different substrates. In that respect PtkA seems to function as a highly connected signal integration device.

    The definition and derivation of a 5-year, 0.125deg, 3-hourly atmospheric forcing dataset for the South America continent is described which is appropriate for use in a Land Data Assimilation System and which, because of the limited surface observational networks available in this region, uses remotely sensed data merged with surface observations as the basis for the precipitation and downward shortwave radiation fields. The quality of this data set is evaluated against available surface observations. There are regional difference in the biases for all variables in the dataset, with biases in precipitation of the order 0-1 mm/day and RMSE of 5-15 mm/day, biases in surface solar radiation of the order 10 W/sq m and RMSE of 20 W/sq m, positive biases in temperature typically between 0 and 4 K, depending on region, and positive biases in specific humidity around 2-3 g/Kg in tropical regions and negative biases around 1-2 g/Kg further south.

    2015-08-01

    NASA’s Science Mission Directorate (SMD) created four competitively awarded Science Education and Public Outreach Forums (Astrophysics, Heliophysics, Planetary Science, Earth Science) in 2009. The NASA SMD education and public engagement community and Forum teams have worked together to share the science, the story, and the adventure of SMD's science missions with students, educators, and the public. In doing so, SMD's programs have emphasized collaboration between scientists with content expertise and educators with pedagogy expertise. The goal of the Education Forums has been to maximize program efficiency, effectiveness, and coherence by organizing collaborations that reduce duplication of effort; sharing best practices; aligning products to national education standards; creating and maintaining the NASA Wavelength online catalog of SMD education products; and disseminating metrics and evaluation findings. We highlight examples of our activities over the past six years, along with the role of the scientist-educator partnership and examples of program impact. We also discuss our community’s coordinated efforts to expand the Astro4Girls pilot program into the NASA Science4Girls and Their Families initiative, which partners NASA science education programs with public libraries to engage underrepresented audiences in science.

A longitudinal study was carried out on 121 patients (57 males and 64 females consecutively treated with 257 implants. 108 implants were short. Results. Four (3.6% short implants supporting fixed partial prostheses failed. Similarly, three standard implants supporting fixed partial prostheses and one supporting single-crown prosthesis failed. Mean marginal bone loss (MBL and probing depth (PD of short and standard implants were statistically comparable (P>.05. The 20-year cumulative survival rates of short and standard implants were 92.3 and 95.9%, respectively. The cumulative success rates were 78.3 and 81.4%. The survival rates of short implants in posterior and anterior regions were comparable: 95 and 96.4%, respectively. The difference between survival rates was not significant (P>.05. Conclusions. The high reliability of short implants in supporting fixed prostheses was confirmed. Short and standard implants long-term prognoses were not significantly different. The prognosis of short implants in posterior regions was comparable to that of in anterior regions. Nevertheless, a larger sample is required to confirm this trend.

  15. Clinicopathological Characteristics of Mucinous Breast Cancer: A Retrospective Analysis of a 10-Year Study

    Chen, Bo; Chen, Zhanhong; Wang, Xiaojia

    2016-01-01

    Background Mucinous breast carcinoma (MC) is a special type of breast cancer that presents with a large amount of extracellular mucin. MC comprises approximately 4% of all invasive breast cancers. This type of tumor has a better prognosis and higher incidence in peri- and post-menopausal patients. Pathologically, there are two main subtypes of MC: pure and mixed. In this study, we describe 10 years of experience with MC at the Zhejiang Cancer Hospital in China, specifically, clinical data, histological findings and immunohistochemical features. Methods We identified MC patients who were diagnosed as operable and completed clinical treatment from January 2001 to January 2011. The clinicopathological data included the age at diagnosis, tumor size, TNM stage, presence and number of lymph node (LN) metastases, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) status and p53 expression. If the tumor was defined as mixed mucinous carcinoma (MMC), IHC was performed on a non-mucinous part, such as invasive ductal and lobular cancer. We evaluated the clinical characteristics of all MC patients using chi-square, one-way ANOVA and LSD tests. We also studied the correlations between all of the clinical parameters and LN metastasis in a binary logistic regression analysis. We used ten consecutive years of data that were collected at Zhejiang Cancer Hospital. Results We identified 48 cases of pure mucinous carcinoma (PMC) and 77 cases of MMC. The 48 PMC cases consisted of 38 PMC-A and 10 PMC-B subtypes. The MMCs were divided into two groups, those with partial mixed mucinous breast carcinoma (pMMC, 58 cases) and those with main mixed mucinous breast carcinoma (mMMC, 19 cases). pMMC was defined by tumors with less than 50% mucinous components, while mMMC was defined by tumors where the mucinous component accounted for 50% to 90% of the tumor. No significant differences in the clinicopathological characteristics were noted

    Carr, M. H.

    2013-12-01

    the initial results seemed to be positive then falling as abiotic explanations of the results seemed more plausible. Meanwhile several Soviet spacecraft successfully landed on and returned images from the surface of Venus (1975, 1981), and a radar imager on Pioneer Venus (1978) gave a preview of a complex geology that was to be subsequently revealed in detail by Magellan in 1990. In 1979 attention shifted to the outer planets as the two Voyager spacecraft flew by Jupiter revealing the volcanic plumes of Io and the distinctive geology of each of the Galilean satellites. In 1978 I joined the Galileo imaging team but the mission suffered a series of mishaps and we spent almost 20 years repeatedly re-planning the Galilean satellite tour and the imaging sequences before we were rewarded in 1995 with unprecedented views of the satellites, particularly of Io's volcanoes and Europa's ice rafts. Meanwhile the Mars program had stalled. Orbiters, landers, sample returns, penetrators, networks, balloons, airplanes were all studied and restudied. After a 20 year gap, Mars exploration was successfully renewed in 1997 with Pathfinder and Global Surveyor. Failure of two Mars missions in 1999 caused another re-structuring of the program but since that time the Mars program has been remarkably successful, although we still await sample return.

    Smith, Denise A.; Peticolas, Laura; Schwerin, Theresa; Shipp, Stephanie

    2014-06-01

    NASA’s Science Mission Directorate (SMD) created four competitively awarded Science Education and Public Outreach Forums (Astrophysics, Heliophysics, Planetary Science, Earth Science) in 2009. The objective is to enhance the overall coherence of SMD education and public outreach (E/PO), leading to more effective, efficient, and sustainable use of SMD science discoveries and learning experiences. We summarize progress and next steps towards achieving this goal with examples drawn from Astrophysics and cross-Forum efforts. Over the past five years, the Forums have enabled leaders of individual SMD mission and grant-funded E/PO programs to work together to place individual science discoveries and learning resources into context for audiences, conveying the big picture of scientific discovery based on audience needs. Forum-organized collaborations and partnerships extend the impact of individual programs to new audiences and provide resources and opportunities for educators to engage their audiences in NASA science. Similarly, Forum resources support scientists and faculty in utilizing SMD E/PO resources. Through Forum activities, mission E/PO teams and grantees have worked together to define common goals and provide unified professional development for educators (NASA’s Multiwavelength Universe); build partnerships with libraries to engage underserved/underrepresented audiences (NASA Science4Girls and Their Families); strengthen use of best practices; provide thematic, audience-based entry points to SMD learning experiences; support scientists in participating in E/PO; and, convey the impact of the SMD E/PO program. The Forums have created a single online digital library (NASA Wavelength, http://nasawavelength.org) that hosts all peer-reviewed SMD-funded education materials and worked with the SMD E/PO community to compile E/PO program metrics (http://nasamissionepometrics.org/). External evaluation shows the Forums are meeting their objectives. Specific examples

  20. Morbidity rates on Vanguard Class submarines during nuclear deterrent patrol: a retrospective review over 13 years.

    O'Shea, M K; Scutt, M J

    2009-01-01

    The submarines responsible for the United Kingdom's nuclear deterrent have carried a junior doctor as their medical officer since the program's inception. The Vanguard Class of submarine carries approximately 150 men and deploys for about 3 months at a time. One of the central tenets of submarine operations is to remain undetected and as such the submarine will only surface in an emergency, which may include the evacuation of casualties. The prime reason for carriage of a medical officer is to mitigate against the need to evacuate personnel for medical reasons. We examined the medical section of the patrol reports submitted upon completion of each patrol over a 13 year period to determine both the rates of medical and dental attendance onboard and also the occurrence of potential medical threats to patrol integrity. The most common reasons for attendance were dermatological and musculoskeletal, consistent with previous studies of this population and working environment. There were few dental cases due to the high rates of dental fitness in the pre-sailing crews. Patrol threatening cases occurred at a rate of approximately 1 per 3 patrols, with acute appendicitis being the most common presentation. This progressed to evacuation at a rate of 1 per 15 patrols, with the successful onboard management in 79% of cases. The junior doctor onboard has limited monitoring equipment and formulary, no diagnostic equipment, basic surgical equipment and no opportunity to seek senior advice, and is therefore reliant on clinical judgement. Despite the limitations placed on the doctor on board these submarines they have proven to be effective in reducing the rate of medical evacuation. PMID:20180431

    Background Use of robotic systems for minimally invasive surgery has rapidly increased during the last decade. Understanding the causes of adverse events and their impact on patients in robot-assisted surgery will help improve systems and operational practices to avoid incidents in the future. Methods By developing an automated natural language processing tool, we performed a comprehensive analysis of the adverse events reported to the publicly available MAUDE database (maintained by the U.S. Food and Drug Administration) from 2000 to 2013. We determined the number of events reported per procedure and per surgical specialty, the most common types of device malfunctions and their impact on patients, and the potential causes for catastrophic events such as patient injuries and deaths. Results During the study period, 144 deaths (1.4% of the 10,624 reports), 1,391 patient injuries (13.1%), and 8,061 device malfunctions (75.9%) were reported. The numbers of injury and death events per procedure have stayed relatively constant (mean = 83.4, 95% confidence interval (CI), 74.2–92.7 per 100,000 procedures) over the years. Surgical specialties for which robots are extensively used, such as gynecology and urology, had lower numbers of injuries, deaths, and conversions per procedure than more complex surgeries, such as cardiothoracic and head and neck (106.3 vs. 232.9 per 100,000 procedures, Risk Ratio = 2.2, 95% CI, 1.9–2.6). Device and instrument malfunctions, such as falling of burnt/broken pieces of instruments into the patient (14.7%), electrical arcing of instruments (10.5%), unintended operation of instruments (8.6%), system errors (5%), and video/imaging problems (2.6%), constituted a major part of the reports. Device malfunctions impacted patients in terms of injuries or procedure interruptions. In 1,104 (10.4%) of all the events, the procedure was interrupted to restart the system (3.1%), to convert the procedure to non-robotic techniques (7.3%), or to

    Full Text Available Abstract Background Viral respiratory tract infections (RTI are relatively understudied in Southeast Asian tropical countries. In temperate countries, seasonal activity of respiratory viruses has been reported, particularly in association with temperature, while inconsistent correlation of respiratory viral activity with humidity and rain is found in tropical countries. A retrospective study was performed from 1982-2008 to investigate the viral etiology of children (≤ 5 years old admitted with RTI in a tertiary hospital in Kuala Lumpur, Malaysia. Methods A total of 10269 respiratory samples from all children ≤ 5 years old received at the hospital's diagnostic virology laboratory between 1982-2008 were included in the study. Immunofluorescence staining (for respiratory syncytial virus (RSV, influenza A and B, parainfluenza types 1-3, and adenovirus and virus isolation were performed. The yearly hospitalization rates and annual patterns of laboratory-confirmed viral RTIs were determined. Univariate ANOVA was used to analyse the demographic parameters of cases. Multiple regression and Spearman's rank correlation were used to analyse the correlation between RSV cases and meteorological parameters. Results A total of 2708 cases were laboratory-confirmed using immunofluorescence assays and viral cultures, with the most commonly detected being RSV (1913, 70.6%, parainfluenza viruses (357, 13.2%, influenza viruses (297, 11.0%, and adenovirus (141, 5.2%. Children infected with RSV were significantly younger, and children infected with influenza viruses were significantly older. The four main viruses caused disease throughout the year, with a seasonal peak observed for RSV in September-December. Monthly RSV cases were directly correlated with rain days, and inversely correlated with relative humidity and temperature. Conclusion Viral RTIs, particularly due to RSV, are commonly detected in respiratory samples from hospitalized children in Kuala Lumpur

    Objective To understand the disease burden due to Herpes Zoster (HZ) among people aged ≥50 years old in China and provide baseline data for future similar studies, and provide evidence for development of herpes zoster vaccination strategy. Methods Retrospective cohort study was conducted in 4 townships and one community. A questionnaire was used to collect information on incidence and cost of HZ among people aged ≥ 50 years old. Results The cumulative incidence rate was 22.6/1,000 among people aged ≥ 50 years old. The average annual incidence rate of HZ was 3.43/1,000 among people aged ≥ 50 years old in 2010–2012. Cumulative incidence and average annual incidence rate increased with age: the cumulative incidence of HZ among people aged ≥ 80 years old was 3.34 times of that among 50- years old (52.3/1000vs15.7/1,000); average annual incidence rate rises from 2.66/1,000 among 50- years old to 8.55/1,000 among 80- year old. Cumulative incidence and average annual incidence rate for females were higher than that for males (cumulative incidence, 26.5/1000vs18.7/1,000; annual incidence rate, 3.95/1000vs2.89/1,000). Cumulative incidence and average annual incidence rate in urban were higher than in rural (cumulative incidence, 39.5/1000vs 17.2/1,000; annual incidence rate, 7.65/1000vs2.06/1,000). The hospitalization rate of HZ was 4.53%. And with the increase of age, the rate has an increasing trend. HZ costs 945,709.5 RMB in total, corresponding to 840.6 RMB per patient with a median cost of 385 RMB (interquartile range 171.7–795.6). Factors associated with cost included the first onset year, area, whether hospitalized and whether sequelae left. Conclusion Incidence rate, complications, hospitalization rate and average cost of HZ increase with age. We recommend that the HZ vaccinations should target people aged ≥50 years old if Zoster vaccine is licensed in China. PMID:27055179

  4. Smaller brain size likely in young adults (<40 years old) with depressive symptoms compared to healthy controls. A retrospective study

    The aim of this study was to determine whether the brain size of young patients with depressive symptoms is smaller than that of healthy controls using magnetic resonance imaging (MRI). We retrospectively evaluated brain size by calculating the ratio of the brain area to that of the skull (the brain-to-skull ratio) on routine MRI scans including the splenium of the corpus callosum obtained from 19 patients <40 years old with depressive symptoms in 2009. The controls were 12 healthy individuals <40 years old who underwent MRI for medical examinations. The mean brain-to-skull ratio of the control group was 0.850±0.022 (range 0.822-0.889), and that of the patient group was 0.819±0.041 (range 0.756-0.878). An unpaired t-test showed a significant difference in the brain-to-skull ratios between these groups (P=0.011). In particular, in 7 of the 19 patients with longer duration of illness and more severe symptoms, the brain-to-skull ratio was 89%-92% of the mean ratio of the control group. The brain size of young patients with depressive symptoms appears to be smaller than that of healthy controls. (author)

    The epidemiology of invasive fungal infections has recently changed in immunosuppressed populations as a result of HIV infection, organ transplant, chemotherapy and in elderly patients. The diagnosis of invasive fungal infections by culture is prolonged since fungi grow slowly in vitro. we wanted to estimate the frequency of fungemia diagnoses established through the Clinical Mycology Laboratory over the past 10 years; through a retrospective study; data was obtained from the laboratory patient registry in the Infectious Disease Hospital's laboratory registry of patients with a systemic fungal isolate between 2005 and 2014. One hundred and thirty two (132) systemic fungal infections were identified. They were more prevalent in males, in the age group between 20 and 59 years and in patients with a diagnosis of AIDS. The most frequently isolated agents belonged to the genus Candida and others such as Histoplasma sp., Cryptococcus sp., Aspergillus sp., and Coccidioides sp. Of all blood and bone marrow cultures received 17.9% had fungal development; of these, in 70% of cases it was through blood cultures. In general, fungal agents were not diagnostically suspected. We identified that Sixty percent (60%) of fungemias developed in AIDS patients, followed by patients with sepsis. The most common agents belonged to the genus Candida, predominantly the albicans species. They were more frequently identified by blood culture than by bone marrow culture. Invasive fungal infections have not followed a usual clinical pattern and are not easily recognizable. PMID:27118806

    Full Text Available Background This paper discusses the treatment protocol for patients with frostbite.Methods We performed a retrospective analysis of a series of 17 patients with second- andhigher-degree frostbite who had been treated at our medical institution between 2010 and2012.Results Our clinical series of patients (n=17 included 13 men and four women, whosemean age was 42.4±11.6 years (range, 22-67 years. The sites of injury include the foot in sixpatients (35.3%, the hand in six patients (35.3% and the facial region in five patients (29.4%.Seven patients with second-degree frostbite were completely cured with only conservativetreatment during a mean period of 12.7±3.3 days (range, 8-16 days. Of the five patients withthird-degree frostbite, two underwent skin grafting following debridement, and the remainingthree achieved a complete cure with conservative treatment during a mean period of 35±4.3days (range, 29-39 days. Five patients with fourth-degree frostbite were treated with surgicalprocedures including amputation.Conclusions With the appropriate conservative management in the early stage of onset,surgeons should decide on surgery after waiting for a sufficient period of time until thedemarcation of the wound. Continuous management of patients is also needed to achievefunctional recovery after a complete cure has been achieved. This should also be accompaniedby patient education for the avoidance of re-exposure to cold environments.

  7. Outcomes and indications for intervention in non-operative management of paediatric liver trauma: A 5 year retrospective study

    Aim: To determine the applicability of accurate computed tomography (CT) evaluation and embolization as non-operative management for liver trauma in a paediatric population. Material and methods: A retrospective observational study of 37 children (mean age 10.5 years) with hepatic trauma (28 blunt, 9 penetrating) admitted to a trauma referral centre over a 5 year period. All patients were evaluated with CT and scored with an Association for the Surgery of Trauma score. Inpatient information was reviewed for demographics, associated injuries, modes of management, efficacy and complications of management, and outcome. Statistical analysis was performed. Results: There were seven contusions, two grade I, two grade II, nine grade III, and 17 grade IV liver lacerations. Only two patients (grade IV, penetrating) underwent surgery for the management of bowel perforation. All children had non-surgical treatment of their liver trauma: three cases (grade IV) had primary angiography due to CT evidence of active bleeding and embolization was performed in two of these. Seven patients (two grade III, five grade IV) had angiography during the follow-up for evidence of a complicating pseudoaneurysm and embolization was performed in six of them. Embolization was successful in all the children; one minor complication occurred (cholecystitis). Endoscopic retrograde cholangiopancreatography (ERCP) plus stenting was performed in two cases for a bile leak. All 37 children had a positive outcome. Conclusion: The present study demonstrates that non-operative management of hepatic trauma is applicable to children and may have a higher success rate than in adults

    The aim of this study was to evaluate retrospectively biologic and technical complications as well as clinical and radiographic outcomes of patients treated with 4 implants according to the All-on-4 protocol and followed up to 7 years of function. Data from 56 consecutive patients presenting complete edentulous jaw, aged 18 years or older, treated between January 2008 and December 2013, were evaluated. The outcomes were implant and prosthetic survival and success rates, any complications, and marginal bone loss (MBL). Two-hundred twenty-four implants were placed in 56 patients. During the entire follow-up, 1 maxillary implant but no prosthesis failed during the healing process. Fourteen patients experienced 1 complication each (10 technical, 4 biologic). The overall implant and prosthetic success rate was 98.2% and 82.1%, respectively. All complications were considered as minor and successfully resolved chairside. A mean MBL of 1.30 ± 0.63 mm was observed at the last follow-up. Statistically significant difference was found for postextractive implants (0.79 ± 0.26) vs implants placed in healed sites (1.03 ± 0.46; P = 0.024). Within the limits of the present study, the All-on-4 concept may be a valuable surgical and prosthetic option for the treatment of complete edentulous jaws. However, minor technical and biologic complications can occur. Further long-term prospective data with primary outcomes focused on success rates are needed. PMID:26652901

  10. A 10-year review of four academic nurse-managed centers: challenges and survival strategies.

    King, Eunice S

    2008-01-01

    Since 1985, there has been rapid growth in nurse-managed health centers (NMHCs). Many were established by academic schools of nursing, and several have closed. The Independence Foundation undertook this study to identify the challenges and survival strategies employed by four academic nurse-managed center grantees during a 10-year period. Data from Foundation records, interviews with directors and staff from the centers and the National Nursing Centers Consortium, a focus group with center founders, and field notes were analyzed for themes related to the centers' challenges and survival strategies. Although the centers faced many challenges from the sociopolitical environment, the community, and their parent organizations, the most difficult challenge was achieving financial sustainability, which was attainable only by obtaining cost-based reimbursement. Because of existing health policies, that was possible only through organizational restructuring and affiliation with an existing federally qualified health center. The future of nursing centers depends upon favorable health policies, data documenting centers' effectiveness, and adequate preparation of the next generation of nursing center directors and practitioners.
