    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

    2013-01-01

    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...

  13. 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

  17. The American Board of Radiology Holman Research Pathway: 10-Year Retrospective Review of the Program and Participant Performance

    Introduction: In 1999, the American Board of Radiology (ABR) implemented an innovative training program track in diagnostic radiology (DR) and radiation oncology (RO) designed to stimulate development of a cadre of future academic researchers and educators in the 2 disciplines. The program was designated the Holman Research Pathway (HRP). An in-depth retrospective review of initial certification examination performance, post-training career choices, and academic productivity has not been written. This report represents a 10-year retrospective review of post-training performance of a cohort of trainees who have had sufficient time to complete their training and initial certification process and to enter practice. Methods and Materials: All pertinent proceedings of the ABR and Accreditation Council for Graduate Medical Education (ACGME) Residency Review Committees for DR and RO between 1997 and May 2011 were reviewed. Thirty-four HRP candidates who fulfilled the established evaluation criteria were identified, and their ABR data files were analyzed regarding performance on the qualifying and certifying examinations. All candidates were contacted directly to obtain a current curriculum vitae. Results: Twenty candidates in RO and 14 candidates in DR were identifiable for review. All candidates attained initial certification. At the time of analysis, 23 of 33 (66.6%) candidates were employed in full-time academic practice (1 DR candidate remained in a fellowship and was not evaluated regarding employment status). Fifteen of 20 (75%) RO candidates were in faculty positions compared with 7 of 13 (53.8%) DR trainees. Additional academic productivity metrics are reported. Conclusions: A high percentage of HRP trainees remained in academic practice and demonstrated significant academic productivity as measured by manuscript authorship and research support. Additional time and observation will be needed to determine whether these findings will be sustained by past, current

  2. 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.

  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. Women and young adults at the time of the earthquake appear to be the most vulnerable groups regarding the psychological effects of the event. PMID:18414131

    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

  5. Periodontal healing two and four years after impacted lower third molar surgery. A comparative retrospective study.

    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.

    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.

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

  3. Spectrum of autoimmune vesiculobullous diseases in Iran: a 13-year retrospective study

    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

    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.

  5. 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.

  6. 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

    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.

    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

    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

    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.

  17. 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.

    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.

    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.

    2011-04-01

    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.

  1. 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.

    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.

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

    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

    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%.

    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

  8. 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.

    2014-12-01

    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.

    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.

  12. 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.

    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

    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

    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.

    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.

    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.

    Making the transition to higher education requires learners to become increasingly responsible for regulating their own learning. However, not all learners will have developed, or indeed be aware of, the various strategies that can be utilised to aid learning and improve academic achievement. Over the past year, we have piloted a new learning skills programme designed to support learners who have underachieved academically since commencing higher education. One of the aims of this support pro...

    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.

    2016-07-01

    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 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

    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 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.

  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.

    2015-09-01

    Full Text Available OBJECTIVES: A Retrospective study to review and provide a detailed analysis of percutaneous nephrolithotomy for management of renal calculus disease. PLACE AND DURATION: The retrospective study was conducted by the Dept. of Urology, Mahatma Gandhi Medical College and Hospital, Jaipur. We reviewed the medical records of 1000 patients who underwent percutaneous nephrolithotomy for renal calculus disease from March 2010 to March 2015. METHODS: Patients with stones of various sizes and characteristics in the kidney and upper ureter were included in the study. The duration of the procedure, Perioperative analysis and intra and postoperative complications were reviewed. Mean age of inclusion were 2 to 75 years. Size of stones varying from 9mm to 7cms. RESULTS: Total of 1000 cases was included in the study consisting of 657 males and 343 females. Mean age of patient was 32 years (2 - 75 years. Calculus was more common in t he right side than the left side. Mean operating time was 75mins. Complications occurred in 446 cases, but most of them were minor. CONCLUSION: Percutaneous nephrolithotomy is the procedure of choice for management of renal calculus disease, although assoc iated with a marginally higher complication rate but most of them were minor further these can be overcome by establishing a protocol under skilled surgical experience. To decrease lung and pleural injury, we recommend a subcostal approach if possible. To decrease solid organ injury, we recommend using complete prone position

Refractive and central corneal curvature data with 6-year or a longer follow-up period of 70 patients were retrieved: 34 children (15 boys and 19 girls, aged 9.2 ± 1.8 years wore orthokeratology lenses and 36 (20 boys and 16 girls, aged 10.2 ± 2.0 years wore spectacles. Myopic progression was determined as the change of myopia from the baseline to the final visit.Results: No statistically significant differences (P > 0.05 in age, central flat corneal curvatures, baseline refractive error, or follow-up period were observed between the two groups. Average myopic progression of the overnight orthokeratology contact lens cohort (-0.37 ± 0.49 D was significantly less (P < 0.001 than of the single-vision spectacle group (-2.06 ± 0.81 D over about 7 years.Conclusion: Our preliminary 7-year data support the claim that overnight orthokeratology contact lenses may be a feasible clinical method for myopic progression control. Prospective and randomized investigations are warranted to overcome the limitations of this retrospective study.Keywords: myopia, contact lens, orthokeratology, myopia progression

    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

    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

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.

  13. 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.

    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.

  15. 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

    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.

    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

    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.

  20. 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.

    2016-08-01

    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.

    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.

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. CONCLUSIONS: The PPTCT programme is effective and has reduced the rate of transmission from mother to child and with present triple drug therapy a further reduction is expected.

    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

    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.

    2000-12-01

    A retrospective study of patients referred to the Department of Oral and Maxillofacial Surgery at Singapore General Hospital/National Dental Centre with mandibular fractures over a 3-year period from June 1995 to May 1998 was carried out. The cause, age, sex, race and anatomical distribution of the fractures were analysed for each of the 123 patients. The main cause of trauma was road traffic accidents (RTAs) (35.8%), of which 79.5% were motorcyclists. The highest incidence of trauma was in the 20-29 year age group (46.3%). Males outnumbered females in a ratio of 7.8:1. The parasymphysis was the most common site of injury (30.9%), and combined condylar and parasymphyseal fractures (26.0%) was the most common combination seen. PMID:11699366

  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.

    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.

  3. 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.

  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. The healthcare personals and thepublic body must be instructed to diagnose the gynecologicalcancer cases especially the

    Full Text Available Percutaneous nephrolithotomy has become the cornerstone and one of several procedures developed over the past three decades, marking a positive trend of minimally invasive procedures in modern urology practices. The planning, patient selection and an effe ctive perioperative protocol are crucial for the outcome of PCNL. Although standardized techniques established for the management of renal and upper ureteric calculus is widely used and accepted, we present a study of 500 cases of PCNL by supracostal punct ure and its consequences and study the efficacy and safety of a supracostal approach. Objective: To evaluate a supracostal approach for percutaneous nephrolithotomy (s - PCNL of renal calculus disease, through a retrospective approach and review the efficac y and safety of procedure in comparison to previous studies. Patients and Duration: The retrospective study was conducted by the Dept. of Urology, Mahatma Gandhi Medical College and Hospital, Jaipur. We reviewed the medical records of 500 patients who unde rwent PCNL by a supracostal access for renal calculus disease from March 2010 to March 2015 . METHOD: Patients with stones of various sizes and characteristics in the kidney and upper ureter were included in the study. Patients were studied for safety of th e supracostal approach and its associated complications, including operative time and success rate. Mean age of inclusion was 18 to 65 years. RESULTS: There were 500 patients with renal calculus disease. Among them 346(69.2% were males and 154 (30.8% fem ales. Calculus were noted in the upper calyx in 157(31.4%, 55(11% in the middle calyx, 121(24.2% in the renal pelvis, 47(9.4% staghorn and partial staghorn calculus, 8(1.6% in the lower calyx and 112(22.4% in the upper ureter.

  17. 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. After 20 year of exposure there is decrease in no. of cases because cases do not survive upto that long period. 137 patients out of 300 cases were confirmed Acid Fast Bacilli positive by smear examination. 123 patients out of 300 cases were bacteriologically confirmed by culture. Out of 123 culture positive cases 66 (53.65% were typical Mycobacteria& 57 (46.34% were Atypical Mycobacterium. M. Kansasii(28, M. Scrofulaceum ( 9 ,M. Ulcerans(1 M.

    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

  6. 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

    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

    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.

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.

    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.

    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.

  16. 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

  19. 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

    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

    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

    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.

  6. 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

  7. 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 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.

    Despite recent advances including new therapeutic options and availability of primary prophylaxis in haemophiliacs, haemophilic synovitis is still the major clinical problem in significant patient population worldwide. We retrospectively reviewed our 10-year experience with Y-90 radiosynovectomy to determine the outcome in the knee joints of patients with haemophilic synovitis. Between 2002 and 2012, 82 knee joints of 67 patients with haemophilic synovitis were treated with Y-90 radiosynovectomy. The mean age was 16.8 ± 7.8 years (range: 5-39 years). The mean follow-up period was 39.6 ± 25.6 months (range: 12-95 months). Failure of therapy represented re-bleeding after a radiosynovectomy was used as an end point in patient time to progression (TTP) analysis. The median TTP was calculated as 72.0 ± 3.6 months (95% CI 64.8-79.1 months) in Kaplan-Meier analysis. The 1, 3 and 5-year survival rates were 89%, 73% and 63% respectively. Longer TTP (hazard ratio for progression, 2.5; P = 0.00) was evident in patients who have greater reduction in bleeding frequency within 6 months after radiosynovectomy. We did not find a relationship between the TTP and the following variables: age, type and severity of haemophilia, the presence or absence of inhibitor, the radiological score, range of motion status of joints and the pretreatment bleeding frequency. We concluded that Y-90 radiosynovectomy in knee joint represents an important resource for the treatment of haemophilic synovitis, markedly reducing joint bleeding and long-term durability, irrespective of the radiographic stage and inhibitor status.

    The clinical outcomes of nitinol stents for femoropopliteal arterial (FP) disease in patients on hemodialysis were assessed. Endovascular therapy (EVT) is accepted for symptomatic FP disease. However, the clinical outcomes of patients on dialysis are not well known. A multicenter retrospective study was conducted with data between November 2010 and August 2013. A total of 484 consecutive patients who successfully underwent EVT for FP disease with nitinol stents were recruited and analyzed. Patients were categorized into the hemodialysis group (N = 161) and non-hemodialysis group (N = 323). The primary measure was primary patency verified by duplex ultrasound at a rest peak systolic velocity (PSVR) of >2.5, and secondary measures were freedom from target lesion revascularization (TLR) and major amputation-free survival (AFS). Average follow-up duration was 19.5 ± 13.5 months. The primary patency rate at 3 years was significantly lower in the hemodialysis group than the non-hemodialysis group (33.8 vs. 43.7 %; p = 0.036). Freedom from TLR at 3 years was 55.0 % in the hemodialysis group and 66.1 % in the non-hemodialysis group (p = 0.032). The hemodialysis group showed a significantly lower AFS rate at 3 years than the non-hemodialysis group (86.4 vs. 58.2 %; p < 0.001). In hemodialysis patients, nitinol stent use resulted in a lower patency rate, higher TLR rate, and lower AFS rate compared to non-hemodialysis patients. These data suggest that nitinol stent implantation for FP arteries in hemodialysis patient needs to be reconsidered. PMID:26337619

    2015-10-01

    Full Text Available Background: Adolescent pregnancy also called as teenage pregnancy is a major public health problem worldwide. Adolescence is defined by WHO as a period from 10-19 years. Adolescent pregnancy results from a number of factors like early marriage, lack of education, premarital sexual relations and lack of awareness regarding contraception. The impact of adolescent pregnancy on the teenager and her future generation is disastrous. This includes obstetric complications like anemia, hypertensive disorders, preterm labour, still births and low birth weight babies. The objective of the present study was to compare the obstetric outcome of teenage pregnancy with that of pregnant women of 20-29 years age group. Methods: This was a hospital based retrospective case-control study conducted in a tertiary care teaching hospital in North Kerala from January 2013 to June 2013. Data collection was done from hospital records. The next delivery belonging to 20-29 years age group entered in parturition register after a teenage delivery was taken as control after satisfying inclusion and exclusion criteria. The obstetric outcome was recorded and analysed. Results: The incidence of teenage pregnancy during the study period was 8.48%. 90.89% of teenage pregnant women were primigravidae. 40.7% were anaemic, 18.22% had preterm labor, 14.87% had preeclampsia and 29.5% of the babies had low birth weight. Conclusions: Teenage pregnancy continues to be a major public health problem in India. The young age structure of Indian population favours more number of adolescents in the country. Preventing early marriages and delaying the onset of child bearing may go a long way in decreasing the number of teenage pregnancies. [Int J Reprod Contracept Obstet Gynecol 2015; 4(5.000: 1319-1323

    Full Text Available Background and Objectives. Critically ill obstetric patients are a particularly unique cohort for the intensivist. The objective of this study was to review the indications for admission, demographics, clinical characteristics, and outcomes of obstetric patients admitted to intensive care unit of a medical college hospital in southern India and to identify conditions associated with maternal mortality. Design. Retrospective analysis of pregnant/postpartum (up to 6 weeks admissions over a 1-year result. We studied 55 patients constituting 11.6% of mixed ICU admissions during the study period. Results. The mean APACHE (acute physiology and chronic health evaluation II score of patients at admission was 11.8. Most of the patients (76% were admitted in the antepartum period. The commonest indications for ICU admission were obstetric haemorrhage (51% and hypertensive disorders of pregnancy (18%. 85% of patients required mechanical ventilation and 78% required inotropic support. Conclusions. Maternal mortality was 13%, and the majority of the deaths were due to disseminated intravascular coagulation and multiorgan failure, following an obstetric haemorrhage. A dedicated obstetric ICU in tertiary hospitals can ensure that there is no delay in patient management and intensive care can be instituted at the earliest.

    Full Text Available Background: Although tracheal tubes are essential devices to control and protect airway in a critical care unit (CCU, they are not free from complications. Aims: To document the incidence and nature of airway accidents in the CCU of a government teaching hospital in Eastern India. Methods: Retrospective analysis of all airway accidents in a 5-bedded (medical and surgical CCU. The number, types, timing, and severity of airway accidents were analyzed. Results: The total accident rate was 19 in 233 intubated and/or tracheostomized patients over 1657 tube days (TDs during 3 years. Fourteen occurred in 232 endotracheally intubated patients over 1075 endotracheal tube (ETT days, and five occurred in 44 tracheostomized patients over 580 tracheostomy TDs. Fifteen accidents were due to blocked tubes. Rest four were unplanned extubations (UEs, all being accidental extubations. All blockages occurred during night shifts and all UEs during day shifts. Five accidents were mild, the rest moderate. No major accident led to cardiorespiratory arrest or death. All blockages occurred after 7th day of intubation. The outcome of accidents were more favorable in tracheostomy group compared to ETT group (P = 0.001. Conclusions: The prevalence of airway accidents was 8.2 accidents per 100 patients. Blockages were the most common accidents followed by UEs. Ten out of the 15 blockages and all 4 UEs were in endotracheally intubated patients. Tracheostomized patients had 5 blockages and no UEs.

  1. Where can we find future K-12 science and math teachers? a search by academic year, discipline, and academic performance level

    Moin, Laura J.; Dorfield, Jennifer K.; Schunn, Christian D.

    2005-11-01

    Responding to the increasing math and science teacher shortage in the United States, this study intended to determine which science, engineering, and math (SEM) majors during which years in their undergraduate education and from which academic performance levels are most interested in K-12 teaching. Results may aid policymakers and practitioners in making most effective use of this traditional undergraduate candidate pool when designing K-12 science and math teacher recruitment programs. A survey of SEM majors from two research-oriented, urban universities is used to assess participants' interest in K-12 teaching both compared to other career choices and in isolation. Results indicate that the more successful targets for K-12 teacher recruitment include (1) SEM undergraduates in their junior and senior years independent of SEM major, (2) SEM undergraduates with mid-academic performance levels independent of SEM major and academic year, and (3) math majors followed by natural science majors and, as least promising targets, engineering majors. Results remain independent from gender and ethnicity variables.

  4. Alma Ata and health for all by the year 2000. The roles of academic institutions.

    Bryant, J H; Zuberi, R W; Thaver, I H

    1991-06-01

    The title of this article raises a complex set of questions. To begin, what happened at Alma Ata and the goal that emanated from it-Health for All by the Year 2000--are themselves controversial matters. At least there are some who are strongly critical of those events and ideas. Even without linking academic institutions with Alma Ata and HFA/2000, a controversy is spawned when one asks about the roles of such institutions in dealing with societal problems--which problems should a university address, and how deeply does a university become engaged in them, particularly if it carries the university out of the cloister into the trenches of societal conflict? Linking academic institutions with Alma Ata and HFA/2000 deepens the controversy but also provides a framework for examining the basic principles on which each is based, and for testing those principles against the realities of real world problems of health development. This article draws on recent critical assessments of both sides of the equation: a recent Consultative Committee to the Director General of WHO that analyzes the successes and failures of PHC development to date, and lays out conditions for greater effectiveness in the future; and the Technical Discussions of WHO on the Roles of Universities in the Strategy for Health for All that review traditional and progressive arguments about the roles of universities in their societies, and how HFA can be seen as fitting into that debate. The thinking contained in these documents provides ample opportunity to examine whether or not academic institutions should have a role that relates to Alma Ata and Health for All, and, in the end, takes the position that, indeed, this is an appropriate role for those universities prepared to make the commitment. The point is also made that such involvement cannot be effective if the scale of the institutional commitment is marginal--it must be substantial and institution-wide. An example is given of the Aga Khan University

  5. A Nation-Wide multicenter 10-year (1999-2008) retrospective clinical epidemiological study of female breast cancer in china

    According to the very limited cancer registry, incidence and mortality rates for female breast cancer in China are regarded to be increasing especially in the metropolitan areas. Representative data on the breast cancer profile of Chinese women and its time trend over years are relatively rare. The aims of the current study are to illustrate the breast cancer profile of Chinese women in time span and to explore the current treatment approaches to female breast cancer. This was a hospital-based nation-wide and multi-center retrospective study of female primary breast cancer cases. China was divided into 7 regions according to the geographic distribution; from each region, one tertiary hospital was selected. With the exception of January and February, one month was randomly selected to represent each year from year 1999 to 2008 at every hospital. All inpatient cases within the selected month were reviewed and related information was collected based on the designed case report form (CRF). The Cancer Hospital/Institute, Chinese Academy of Medical Sciences (CICAMS) was the leading hospital in this study. Four-thousand two-hundred and eleven cases were randomly selected from the total pool of 45,200 patients and were included in the analysis. The mean age at diagnosis was 48.7 years (s.d. = 10.5 yrs) and breast cancer peaked in age group 40-49 yrs (38.6%). The most common subtype was infiltrating ductal carcinoma (86.5%). Clinical stage I & II accounted for 60.6% of 4,211 patients. Three-thousand five-hundred and thirty-four cases had estrogen receptor (ER) and progestin receptor (PR) tests, among them, 47.9% were positive for both. Two-thousand eight-hundred and forty-nine cases had human epidermal growth factor receptor 2(HER-2) tests, 25.8% of them were HER-2 positive. Among all treatment options, surgery (96.9% (4,078/4,211)) was predominant, followed by chemotherapy (81.4% (3,428/4,211). Much less patients underwent radiotherapy (22.6% (952/4,211)) and endocrine

  7. Examining the relationship of ethnicity, gender and social cognitive factors with the academic achievement of first-year engineering students

    Carr, Bruce Henry

    The purpose of the study was to examine the relationships of social cognitive factors and their influence on the academic performance of first-year engineering students. The nine social cognitive variables identified were under the groupings of personal support, occupational self-efficacy, academic self-efficacy, vocational interests, coping, encouragement, discouragement, outcome expectations, and perceived stress. The primary student participants in this study were first-year engineering students from underrepresented groups which include African American, Hispanic American students and women. With this in mind, the researcher sought to examine the interactive influence of race/ethnicity and gender based on the aforementioned social cognitive factors. Differences in academic performance (university GPA of first-year undergraduate engineering students) were analyzed by ethnicity and gender. There was a main effect for ethnicity only. Gender was found not to be significant. Hispanics were not found to be significantly different in their GPAs than Whites but Blacks were found to have lower GPAs than Whites. Also, Pearson correlation coefficients were used to examine the relationship between and among the nine identified social cognitive variables. The data from the analysis uncovered ten significant correlations which were as follows: occupational self-efficacy and academic self-efficacy, occupational self-efficacy and vocational interest, occupational self-efficacy and perceived stress, academic self-efficacy and encouragement, academic self-efficacy and outcome expectations, academic self-efficacy and perceived stress, vocational interest and outcome expectations, discouragement and encouragement, coping and perceived stress, outcome expectations and perceived stress. Next, a Pearson correlation coefficient was utilized to examine the relationship between academic performance (college GPA) of first-year undergraduate engineering students and the nine identified

    Full Text Available Abstract Background Prevalence of pain as a recurrent symptom in children is known to be high, but little is known about children with high impairment from chronic pain seeking specialized treatment. The purpose of this study was the precise description of children with high impairment from chronic pain referred to the German Paediatric Pain Centre over a 5-year period. Methods Demographic variables, pain characteristics and psychometric measures were assessed at the first evaluation. Subgroup analysis for sex, age and pain location was conducted and multivariate logistic regression applied to identify parameters associated with extremely high impairment. Results The retrospective study consisted of 2249 children assessed at the first evaluation. Tension type headache (48%, migraine (43% and functional abdominal pain (11% were the most common diagnoses with a high rate of co-occurrence; 18% had some form of musculoskeletal pain disease. Irrespective of pain location, chronic pain disorder with somatic and psychological factors was diagnosed frequently (43%. 55% of the children suffered from more than one distinct pain diagnosis. Clinically significant depression and general anxiety scores were expressed by 24% and 19% of the patients, respectively. Girls over the age of 13 were more likely to seek tertiary treatment compared to boys. Nearly half of children suffered from daily or constant pain with a mean pain value of 6/10. Extremely high pain-related impairment, operationalized as a comprehensive measure of pain duration, frequency, intensity, pain-related school absence and disability, was associated with older age, multiple locations of pain, increased depression and prior hospital stays. 43% of the children taking analgesics had no indication for pharmacological treatment. Conclusion Children with chronic pain are a diagnostic and therapeutic challenge as they often have two or more different pain diagnoses, are prone to misuse of

    Full Text Available Abstract Background Tracheostomy remains a very important life saving surgical procedure worldwide and particularly in our environment where patients present late in upper airway obstruction. Little work has been done on this subject in our environment and therefore it was necessary to conduct this study to describe our own experiences with tracheostomy, outlining the common indications and outcome of tracheostomized patients in our setting and compare our results with those from other centers in the world. Methods This was a 10-year retrospective study which was conducted at Bugando Medical Centre from January 2001 to December 2010. Data were retrieved from patients' files kept in the Medical record department and analyzed using SPSS computer software version 15.0. Ethical approval to conduct the study was obtained from relevant authority before the commencement of the study. Results A total of 214 patients were studied. The male to female ratio was 3.1: 1. The majority of patients were in the 3rd decade of life. The most common indication for tracheostomy was upper airway obstruction secondary to traumatic causes in 55.1% of patients, followed by upper airway obstruction due to neoplastic causes in 39.3% of cases. The majority of tracheostomies (80.4% were performed as an emergency. Transverse skin crease incision was employed in all the cases. Post-tracheostomy complication rate was 21.5%. Complication rate was significantly higher in emergency tracheostomy than in electives (P Conclusion Upper airway obstruction secondary to trauma and laryngeal tumors still remains the most common indication for tracheostomy in our centre and tracheostomy is still a life saving procedure in the surgical management of airway despite complications which are seen more commonly in paediatric patients. Most of tracheostomy related complications can be avoided by meticulous attention to the details of the technique and postoperative tracheostomy care by skilled

    Full Text Available Glomerular diseases continue to be the leading cause of end-stage renal disease (ESRD globally. Hence, it is important to recognize the pattern of glomerular diseases in different geographical areas in order to understand the patho-biology, incidence and progression of the disorder. Published studies from different centers in Saudi Arabia have reported contradicting results. In this retrospective study, we report our experience at the Armed Forces Hospital, Riyadh, Saudi Arabia. A total of 348 native renal biopsies performed at our center on patients with proteinuria >1 g, hematuria and/or renal impairment during a period of 5 years (between January 2005 and December 2009 were studied by a histopathologist using light microscopy, immunofluorescence and electron microscopy, and were categorized. Results showed that primary glomerular disease accounted for 55.1% of all renal biopsies. The most common histological lesion was focal and segmental glomerulosclerosis (FSGS (27.6%, followed by minimal change disease (MCD (17.7% and membrano-proliferative glomerulonephritis (MPGN (13.0%. Secondary glomerular disease accounted for 37.9% of the glomerular diseases, with lupus nephritis (LN being the most common lesion (54.5%, followed by hypertensive nephrosclerosis (22%, post-infectious glomerulonephritis (7.5%, diabetic nephropathy (DN (6.8% and vasculitides (4.5%. Four percent of all biopsies turned out to be ESRD while biopsy was inadequate in 2.8% of the cases. In conclusion, our study showed that FSGS was the most common primary GN encountered, while LN was the most common secondary GN. We encountered 14 cases of crescentic glomerulonephritis. Also, the prevalence of MPGN, MCD, IgA nephropathy and membranous GN was many folds higher in males when compared with the Western data. We believe that it is mandatory to maintain a Saudi Arabian Renal Biopsy Registry to understand better the pattern of glomerular disease in the Saudi population and to follow

    Objective CT, an important diagnostic tool in the emergency department (ED), might increase the ED length of stay (LOS). Considering the issue of ED overcrowding, it is important to evaluate whether CT use delays or facilitates patient disposition in the ED. Design A retrospective 1-year cohort study. Setting 5 EDs within the same healthcare system dispersed nationwide in Taiwan. Participants All adult non-trauma patients who visited the 5 EDs from 1 July 2011 to 30 June 2012. Interventions Patients were grouped by whether or not they underwent a CT scan (CT and non-CT groups, respectively). Primary and secondary outcome measures The ED LOS and hospital LOS between patients who had and had not undergone CT scans were compared by stratifying different dispositions and diagnoses. Results CT use prolonged patient ED LOS among those who were directly discharged from the ED. Among patients admitted to the observation unit and then discharged, patients diagnosed with nervous system disease had shorter ED LOS if they underwent a CT scan. CT use facilitated patient admission to the general ward. CT use also accelerated patients' admission to the intensive care unit (ICU) for patients with nervous system disease, neoplasm and digestive disease. Finally, patients admitted to the general wards had shorter hospital LOS if they underwent CT scans in the ED. Conclusions CT use did not seem to have delayed patient disposition in ED. While CT use facilitated patient disposition if they were finally hospitalised, it mildly prolonged ED LOS in cases of patients discharged from the ED. PMID:27147387

Demographic, laboratory parameters leading up to biologic therapy and the subsequent pattern of outcomes in either disease were established as a database. Initial failure, subsequent need to change therapy, or need to adjust therapy were evaluated. Kruskal–Wallis (nonparametric tests to compare two groups and Kaplan–Meier survival curve analysis were used to compare outcomes.Results: Over approximately 6 years, 71 CD and 26 UC patients received 999 and 215 infusions, respectively, for a median of 62 months. Of these, 17% for CD and 19% for UC patients were primary failures. Following the start of infliximab, 18% of CD and 11% of UC patients required stoppage and switching to another type of therapy. In either CD or UC patients, 54% or 62%, respectively, continued therapy without the need to change to other treatments. Few serious side effects were noted. No important statistically significant differences in treatment patterns or outcome were observed between the groups.Discussion: Long-term treatment of both inflammatory bowel diseases reflects outcomes of clinical trials.Conclusions: This study emphasizes similarities between CD and UC and reports therapeutic success for an extended time.Keywords: infliximab, inflammatory bowel diseases

    Sports-related injuries can have a substantial impact on the long-term health of student-athletes. The National Collegiate Athletic Association (NCAA) monitors injuries among college student-athletes at member schools. In academic year 2013-14, a total of 1,113 member schools fielded 19,334 teams with 478,869 participating student-athletes in NCAA championship sports (i.e., sports with NCAA championship competition) (1). External researchers and CDC used information reported to the NCAA Injury Surveillance Program (NCAA-ISP) by a sample of championship sports programs to summarize the estimated national cumulative and annual average numbers of injuries during the 5 academic years from 2009-10 through 2013-14. Analyses were restricted to injuries reported among student-athletes in 25 NCAA championship sports. During this period, 1,053,370 injuries were estimated to have occurred during an estimated 176.7 million athlete-exposures to potential injury (i.e., one athlete's participation in one competition or one practice). Injury incidence varied widely by sport. Among all sports, men's football accounted for the largest average annual estimated number of injuries (47,199) and the highest competition injury rate (39.9 per 1,000 athlete-exposures). Men's wrestling experienced the highest overall injury rate (13.1 per 1,000) and practice injury rate (10.2 per 1,000). Among women's sports, gymnastics had the highest overall injury rate (10.4 per 1,000) and practice injury rate (10.0 per 1,000), although soccer had the highest competition injury rate (17.2 per 1,000). More injuries were estimated to have occurred from practice than from competition for all sports, with the exception of men's ice hockey and baseball. However, injuries incurred during competition were somewhat more severe (e.g., requiring ≥7 days to return to full participation) than those acquired during practice. Multiple strategies are employed by NCAA and others to reduce the number of injuries in

    2016-05-01

    Background A remarkable development through the evolution of free flap techniques has led to the modern reconstructive head and neck surgery. This study aimed to review experiences from head and neck free-flap reconstructions performed at our institution over an 18-year period. Methods Between 1995 and 2012, 594 free-flap operations were performed on 541 head and neck patients at the Department of Plastic Surgery, Helsinki University Hospital, Finland. We retrospectively recorded hospital chart data regarding patient demographics, tumor characteristics, surgical treatment, and outcome. Results The mean age of patients increased from 53 years (1995-2000) to 56 (2007-2012), while the gender distribution remained constant (60% males). The most commonly used flap type between 1995 and 2000 was radial forearm flap (50%), while during the periods of 2001 through 2006 and 2007 through 2012 the anterolateral thigh flap was the most common method (42 and 36%, respectively). The number of different flap types and flap combinations increased during these periods (15 flap types during 1995 through 2000; 17 flap types during 2001 through 2006; and 24 flap types during 2007 through 2012). Despite a wider range of flap options used during the period 2001 through 2012, the overall flap survival rate (97%) remained constant. The prevalence of surgical complications decreased from 26% (2001 through 2006) to 21% (2007 through 2012). Conclusions During the study period, the number of flap types increased and reconstructions became more individualized. The overall surgical complication rate decreased although the mean age of patients increased. PMID:26766422

    2015-06-01

    Full Text Available The present study aimed to examine distance learners’ goal profiles and their contrasting patterns of learning and achievements at three different points during an academic year, i.e. in the beginning of the course in relation to learners’ general orientations to learning, at the middle of the course in relation to learners’ completion of an assignment, and towards the end of the course in relation to learners’ preparation for course examination. Two hundred seventy-six adult distance learners completed three survey questionnaires that assessed their motivation and learning at these three learning points. Using person-centred analytical procedures, this study located four groups of learners based on different combinations of mastery and performance-approach goals. MANOVA results have shown that multiple-goal learners (High mastery/High performance, HH who held strong mastery and performance-approach goals used more deep and regulatory strategies and showed a higher level of learning interest across three waves of surveys than did those focusing solely on mastery (HL or performance-approach goals (LH. However, the multiple-goal learners did not have better achievement levels compared to those focusing solely on mastery goals (HL. Given that multiple goal learners learnt with a more engaged pattern, it is less likely that these motivated learners will drop out of distance learning courses and programs. Future studies should explore how these goals can be promoted simultaneously in distance learning.

  5. Three-Year Experience of an Academic Medical Center Ombuds Office.

    Raymond, John R; Layde, Peter M

    2016-03-01

    An ombuds is an individual who informally helps people or groups (visitors) resolve disputes and/or interpersonal conflicts as an alternative to formal dispute resolution mechanisms within an organization. Ombuds are nearly ubiquitous in many governmental, business, and educational settings but only recently have gained visibility at medical schools. Medical schools in the United States are increasingly establishing ombuds offices as part of comprehensive conflict management systems to address concerns of faculty, staff, students, and others. As of 2015, more than 35 medical schools in the United States have active ombuds Web pages. Despite the growing number of medical schools with ombuds offices, the literature on medical school ombuds offices is scant. In this article, the authors review the first three years of experience of the ombuds office at the Medical College of Wisconsin, a freestanding medical and graduate school with a large physician practice. The article is written from the perspective of the inaugural ombuds and the president who initiated the office. The authors discuss the rationale for, costs of, potential advantages of, and initial reactions of faculty, staff, and administration to having an ombuds office in an academic medical center. Important questions relevant to medical schools that are considering an ombuds office are discussed. The authors conclude that an ombuds office can be a useful complement to traditional approaches for conflict management, regulatory compliance, and identification of systemic issues. PMID:26675192

The data gainedfrom questionnaires have been interpreted according to the SPSS package programme frequency dispersion and percentage.According to the data from the questionnaires activity types in Turkey are different from those in USA. Our students prefersports activities and educational groups and they don’t work at weekends, in weekdays they meet their friends after school,spend free time by listening to music, reading book, magazine, newspaper I mean in a passive way. In USA students usuallywork at weekends for getting by on themselves. As a result 2nd education teacher trainees should be told that such short timesare really important for them and they should spend free time in a good way for their future. They should also be unformattedabout improving themselves and they should have some new opportunities about this matter.

  8. An Intervention to Improve Academic Literacies in a First Year University Biology Course

    Roisin Kelly-Laubscher

    2015-02-01

    Full Text Available In South Africa there are many students, especially those from previously underrepresented groups at university, who successfully gain access to university but do not succeed in completing their degree either within the prescribed time or at all.  One of the barriers to student success at university is the difficulty these students have in accessing the literacy practices of the disciplines.  Therefore, within a first year biology course at a South African University, an intervention that focused on the academic literacy practices in biology was introduced. The intervention was designed around the assignment of writing a lab report. This paper describes this intervention and how it impacted on one student’s journey from learning science at school to learning science at university.  A literacy history interview and ‘talk around text’ interviews were used to assess the student’s experience of the intervention. Comparison of the student’s first and final drafts of the report revealed changes in the style and format of his writing. These changes in his report writing as well as in his attitude and motivation for writing the report were facilitated by a better understanding of the expectations of writing in university biology. This understanding was mediated largely through the modelling and deconstruction of the expected genre. This highlights not only the importance of providing first year students with examples of the genres they are  expected to be writing but also the facilitation of their engagement with these new genres. Without these kinds of intervention many students are unlikely to gain access to disciplinary ways of learning and writing, which ultimately may lead to their exclusion from university.

    Highlights: • MWA appears to be a more effective treatment for larger tumors compared with RFA. • Intraoperative MWA outperformed percutaneous MWA. • Complications related to MWA of liver tumors were minor and self limited. - Abstract: Purpose: To retrospectively evaluate the safety and efficacy of microwave ablation (MWA) as treatment for single, focal hepatic malignancies. Materials and Methods: Institutional review board approval was obtained for this HIPAA-compliant study. From December 2003 to May 2012, 64 patients were treated with MWA for a single hepatic lesion, in 64 sessions. Hepatocellular carcinoma (HCC) was treated in 25 patients (geometric mean tumor size, 3.33-cm; 95% CI, 2.65–4.18-cm; range, 1.0–12.0-cm), metastatic colorectal cancer (CRC) was treated in 27 patients (geometric mean tumor size, 2.7-cm; 95% CI, 2.20–3.40-cm; range, 0.8–6.0-cm), and other histological-types were treated in 12 patients (geometric mean tumor size, 3.79-cm; 95% CI, 2.72–5.26-cm; range, 1.7–8.0-cm). Kaplan–Meier (K–M) method was used to analyze time event data. Chi-square and correlation evaluated the relationship between tumor size and treatment parameters. Results: Technical success rate was 95.3% (61/64). Treatment parameters were tailored to tumor size; as size increased more antennae were used (p < 0.001), treatment with multiple activations increased (p < 0.028), and treatment time increased (p < 0.001). There was no statistically significant relationship between time to recurrence and tumor size, number of activations, number of antennae, and treatment time. At one-year, K–M analysis predicted a likelihood of local recurrence of 39.8% in HCC patients, 45.7% in CRC metastases patients, and 70.8% in patients with other metastases. Median cancer specific survivals for patients were 38.3 months for HCC patients, 36.3 months for CRC metastases, and 13.9 months for other histological-types. Complications occurred in 23.4% (15/64) of sessions

  11. Retrospective seasonal prediction of summer monsoon rainfall over West Central and Peninsular India in the past 142 years

    Li, Juan; Wang, Bin; Yang, Young-Min

    2016-06-01

    Prediction of Indian summer (June-September) rainfall on regional scales remains an open issue. The operational predictions of West Central Indian summer rainfall (WCI-R) and Peninsular Indian summer rainfall (PI-R) made by the Indian Meteorological Department (IMD) had no skills during 2004-2012. This motivates the present study aiming at better understanding the predictability sources and physical processes governing summer rainfall variability over these two regions. Analysis of 133 year data reveal that although the lower boundary forcing that associated with enhanced WCI-R and PI-R featured a similar developing La-Nina and "east high west low" sea-level pressure (SLP) dipole pattern across the Indo-Pacific, the anomalous high sea surface temperature (SST) over the northern Indian Ocean and weak low pressure over northern Asia tended to enhance PI-R but reduce WCI-R. Based on our understanding of physical linkages with the predictands, we selected four and two causative predictors for predictions of the WCI-R and PI-R, respectively. The intensified summer WCI-R is preceded by (a) Indian Ocean zonal dipole-like SST tendency (west-warming and east-cooling), (b) tropical Pacific zonal dipole SST tendency (west-warming and east-cooling), (c) central Pacific meridional dipole SST tendency (north-cooling and south-warming), and (d) decreasing SLP tendency over northern Asia in the previous season. The enhanced PI-R was lead by the central-eastern Pacific cooling and 2-m temperature cooling tendency east of Lake Balkhash in the previous seasons. These causative processes linking the predictors and WCI-R and PI-R are supported by ensemble numerical experiments using a coupled climate model. For the period of 1871-2012, the physics-based empirical (P-E) prediction models built on these predictors result in cross-validated forecast temporal correlation coefficient skills of 0.55 and 0.47 for WCI-R and PI-R, respectively. The independent forecast skill is significantly

    It is well established that poor academic performance is related to smoking, but the association between academic well-being and smoking is less known. We measured academic well-being by school burnout and schoolwork engagement and studied their associations with smoking among 14- to 17-year-old schoolchildren in Belgium, Germany, Finland, Italy, the Netherlands, and Portugal. A classroom survey (2013 SILNE survey, N = 11,015) was conducted using the Short School Burnout Inventory and the Schoolwork Engagement Inventory. Logistic regression, generalized linear mixed models, and ANOVA were used. Low schoolwork engagement and high school burnout increased the odds for daily smoking in all countries. Academic performance was correlated with school burnout and schoolwork engagement, and adjusting for it slightly decreased the odds for smoking. Adjusting for socioeconomic factors and school level had little effect. Although high school burnout and low schoolwork engagement correlate with low academic performance, they are mutually independent risk factors for smoking. PMID:27208481

  15. Sense of coherence, self-regulated learning and academic performance in first year nursing students: A cluster analysis approach.

    This paper examines the relationship between nursing students' sense of coherence, self-regulated learning and academic performance in bioscience. While there is increasing recognition of a need to foster students' self-regulated learning, little is known about the relationship of psychological strengths, particularly sense of coherence and academic performance. Using a prospective, correlational design, 563 first year nursing students completed the three dimensions of sense of coherence scale - comprehensibility, manageability and meaningfulness, and five components of self-regulated learning strategy - elaboration, organisation, rehearsal, self-efficacy and task value. Cluster analysis was used to group respondents into three clusters, based on their sense of coherence subscale scores. Although there were no sociodemographic differences in sense of coherence subscale scores, those with higher sense of coherence were more likely to adopt self-regulated learning strategies. Furthermore, academic grades collected at the end of semester revealed that higher sense of coherence was consistently related to achieving higher academic grades across all four units of study. Students with higher sense of coherence were more self-regulated in their learning approach. More importantly, the study suggests that sense of coherence may be an explanatory factor for students' successful adaptation and transition in higher education, as indicated by the positive relationship of sense of coherence to academic performance.

  19. Integrating Field-Centered, Project Based Activities with Academic Year Coursework: A Curriculum Wide Approach

    Kelso, P. R.; Brown, L. M.

    2015-12-01

    Based upon constructivist principles and the recognition that many students are motivated by hands-on activities and field experiences, we designed a new undergraduate curriculum at Lake Superior State University. One of our major goals was to develop stand-alone field projects in most of the academic year courses. Examples of courses impacted include structural geology, geophysics, and geotectonics, Students learn geophysical concepts in the context of near surface field-based geophysical studies while students in structural geology learn about structural processes through outcrop study of fractures, folds and faults. In geotectonics students learn about collisional and rifting processes through on-site field studies of specific geologic provinces. Another goal was to integrate data and samples collected by students in our sophomore level introductory field course along with stand-alone field projects in our clastic systems and sequence stratigraphy courses. Our emphasis on active learning helps students develop a meaningful geoscience knowledge base and complex reasoning skills in authentic contexts. We simulate the activities of practicing geoscientists by engaging students in all aspects of a project, for example: field-oriented project planning and design; acquiring, analyzing, and interpreting data; incorporating supplemental material and background data; and preparing oral and written project reports. We find through anecdotal evidence including student comments and personal observation that the projects stimulate interest, provide motivation for learning new concepts, integrate skill and concept acquisition vertically through the curriculum, apply concepts from multiple geoscience subdisiplines, and develop soft skills such as team work, problem solving, critical thinking and communication skills. Through this projected-centered Lake Superior State University geology curriculum students practice our motto of "learn geology by doing geology."

  4. [Preschool familial environment and academic difficulties: A 10-year follow-up from kindergarten to middle school].

    Câmara-Costa, H; Pulgar, S; Cusin, F; Dellatolas, G

    2016-02-01

    The persistence of academic difficulties from childhood through adulthood has led researchers to focus on the identification of the early factors influencing children's subsequent achievement in order to improve the efficient screening of children who might be at risk of school failure. The foundations of academic achievement can be accurately traced back to the preschool years prior to children's entry in formal schooling and are largely influenced by environmental determinants. Importantly, some environmental conditions act as early risk factors undermining children's later academic achievement due to the well-established relation between underachievement and exposure to moderate to high levels of environmental risk. In the present study, we aimed to investigate the longitudinal effects of environment-level factors (sociodemographic and family characteristics) and early risk exposure at kindergarten on children's subsequent academic achievement at the end of middle school (grade 9). The sample of analysis comprised 654 kindergarteners aged 5-6 years (2001-2002 school year) followed through the end of middle school when they were aged 14-15 years (2010-2011 school year). At kindergarten, assessment included questionnaire-based measures of sociodemographic and family background characteristics. These included an original set of information pertaining to family background including parental nationality, education level, history of reading difficulties, type of early childcare, family situation, family size, and language-based bedtime routines, as well as individual-level factors such as children's first language, medical history, language delay, birth weight, age of walking onset, and gestation period. At grade 9, outcome measures were composed of children's results in the national evaluations performed at the end of middle school ("Diplôme National du Brevet"), or history of repetition for a second year of the same class. The results indicated that all family

    Fluorescence in situ hybridization (FISH) is a powerful method largely used for detecting chromosomal rearrangements, translocations in particular, which are important biomarkers for dose assessment in case of human exposure to ionizing radiation. To test the possibility of using the translocation analysis by FISH-painting method in retrospective dose assessment, we carried out in vitro experiments in irradiated human lymphocytes, in parallel with the analysis of translocations in lymphocytes from 10 individuals, who were exposed to {sup 137}cesium in the Goiania (Brazil) accident (samples collected 10 years after exposure). The in vitro dose-response curve for the genomic translocation frequencies (FGs) fits a linear quadratic model, according to the equation: Y=0.0243X{sup 2}+0.0556X. The FG values were also calculated for the individuals exposed to {sup 137}cesium, ranging from 0.58 to 5.91 per 100 cells, and the doses were estimated and compared with the results obtained by dicentric analysis soon after the accident, taking the opportunity to test the validity of translocation analysis in retrospective biodosimetry. A tentative of retrospective dosimetry was performed, indicating that the method is feasible only for low level exposure (below 0.5 Gy), while for higher doses there is a need to apply appropriate correction factors, which take into consideration mainly the persistence of chromosomal translocations along with time, and the influence of endogenous and exogenous factors determining the inter-individual variability in the cellular responses to radiation.

    Tabrizi, Reza; Aliabadi, Ehsan; Maleki, Mohammad Javad; Barouj, Mehrdad Dehghanpour

    2016-07-01

    Adenoid cystic carcinoma (ACC) is both invasive and clinically unpredictable, and our aim was to evaluate the factors that affect its recurrence in the palate. We retrospectively studied 38 patients who had ACC of the palate treated surgically, and the outcome measure was recurrence during the mean (SD) followup time of 55 (18) months. Age, sex, T-stage, bony involvement, duration of follow up, histological type, perineural invasion, and surgical margins were all recorded. Results showed no association between recurrence, and age or histopathological types. However, T-stage (p=0.001), sex (p=0.04), and bony and perineural involvement (p=0.01 in each case) were significantly associated with recurrent tumour. Close superior and posterior margins (< 2mm) were also associated with recurrence (p=0.001 in each case). Large tumours with bony and perineural involvement, together with close superior and posterior surgical margins, had a higher risk of recurrence. PMID:27094499

Diagnosis was made according to the criteria modified by Guard. All 40 patients had at least two major criteria, namely change in consciousness and hypoxia. Twenty patients (50%) presented with full-blown clinical features. Prompt respiratory support with oxygen mask or nasal prongs was the first line of treatment. Forty per cent of patients responded well, whereas the others had to be advanced to endotracheal intubation and mechanical ventilation with positive end expiratory pressure. Steroids were given to 80% of patients and better results were achieved than in the group not treated with steroids. The mortality rate was low (2.5%) and only four patients suffered prolonged cerebral sequelae. The clinical course and prognosis cannot be predicted from the severity of the fracture. PMID:2224610

    Academic performance is a concern of paramount importance in Spain, where around of 30 % of the students in the last two courses in high school, before to access to the labor market or to the university, do not achieve the minimum knowledge required according to the Spanish educational law in force. In order to analyze this problem, we propose a random network model to study the dynamics of the academic performance in Spain. Our approach is based on the idea that both, good and bad study habits, are a mixture of personal decisions and influence of classmates. Moreover, in order to consider the uncertainty in the estimation of model parameters, we perform a lot of simulations taking as the model parameters the ones that best fit data returned by the Differential Evolution algorithm. This technique permits to forecast model trends in the next few years using confidence intervals.

  17. "The university didn't actually tell us this is what you have to do": Social inclusion through embedding of academic skills in first year professional courses

    Sophie Goldingay

    2014-03-01

    Full Text Available The widening participation agenda means that students will be entering degree courses with increasingly diverse needs, particularly with respect to the academic skills necessary for successful tertiary study in Australia. This paper presents findings from a mixed methods project investigating first year social work students’ perceived role in academic skills and their development. Students expressed the perception that academic skill requirements and how they would be assessed should be made explicit, and identified a stigma associated with accessing study support services. The paper concludes that an intentional design strategy, such as embedding academic skills into the curriculum, helps bridge the different expectations between academics and students in the teaching and learning of academic skills, and hence constitutes a socially inclusive strategy to teaching professional courses such as social work, within higher education.  Recommendations to enhance the success and sustainability of such an initiative in the current higher education environment are offered.

    This study reports our 15-year experience, in Sicily, with the use of voice prostheses, analysing the different variables that have influenced the success or failure of speech rehabilitation. The retrospective clinical analysis was carried out by reviewing the clinical histories of 95 patients with laryngeal cancer, in whom a voice prosthesis had been placed by trachea-oesophageal puncture between 1998 and 2013. Age, type of tumour, type of surgery, use of prior radiation therapy, type of puncture, prosthesis used and its duration, number of replacements, complications and causes for prosthetic success or failure were analysed. The results showed a mean of Harrison-Robillard-Schultz (HRS) TEP rating scale of 11.8 in primary TEP and 12.6 in secondary TEP (P =0.613). PORT did not affect overall rehabilitation success. In these patients, the mean HRS rating scale was 11.2, with long-term success of 85% (P =0.582). In patients over 70 years old, long-term success was 82.5%, with 78% in primary and 86% in secondary TEP, the mean HRS was 11.2 in primary and 12 in secondary TEP (P =0.648). In total, long-term success was 87.5%, with 84% in primary and 91% in secondary TEP. The results obtained by retrospective analysis of 15 years of prosthetic rehabilitation in the Sicilian territory highlighted standard rehabilitation, in terms of intra and postoperative complications, fistula related pathology and overall success.

    2014-01-01

    There has been growing concern in the higher education sector in South Africa about the high number of students with low academic literacy (AL) levels who are gaining entry into the sector. This influx necessitated the introduction of academic literacy interventions which are aimed at supporting these students in meeting the academic literacy requirements of university education. As a result, the tertiary sector has seen a growing number of AL interventions, each catering for a different cont...

  20. A retrospective study of 5-year outcomes of radiotherapy for gastric mucosa-associated lymphoid tissue lymphoma refractory to Helicobacter pylori eradication therapy

    The favorable response rate of radiotherapy for localized gastric mucosa-associated lymphoid tissue lymphoma refractory to Helicobacter pylori eradication has been demonstrated. However, there are limited data available on the long-term outcomes. The aim of this retrospective study was to evaluate the long-term outcomes of radiotherapy for localized gastric mucosa-associated lymphoid tissue lymphoma refractory to Helicobacter pylori eradication. Thirty-four consecutive patients with localized gastric mucosa-associated lymphoid tissue lymphoma that were refractory to eradication were treated with radiotherapy (a total dose of 30 Gy). The response and adverse events of radiotherapy were retrospectively analyzed as short-term outcomes, and recurrence-free, overall and disease-specific survival rates were calculated as long-term outcomes. Thirty-three (97.1%) patients achieved complete remission and radiotherapy was well tolerated. One patient underwent emergency gastrectomy due to severe hematemesis. Of the 34 patients during the median follow-up period of 7.5 (1.2-13.0) years, one patient had local recurrence after 8.8 years, one patient underwent surgery for bowel obstruction secondary to small bowel metastasis after 5.1 years and one patient had pulmonary metastasis after 10.9 years. Pathologically, all three recurrences revealed mucosa-associated lymphoid tissue lymphoma without any transformation to high-grade lymphoma. None died of gastric mucosa-associated lymphoid tissue lymphoma. The 5-year recurrence-free survival rate was 97.0%. The 5-year overall survival rates and disease-specific survival rates were 97.0 and 100%, respectively. Radiotherapy in patients with localized gastric mucosa-associated lymphoid tissue lymphoma refractory to Helicobacter pylori eradication can achieve excellent overall survival. However, long-term surveillance is necessary to identify late recurrences. (author)

  2. The affect of parenting style on academic achievement in early years education

    Nel, Maria Elizabeth

    2013-01-01

    Lack of parental involvement is one of the biggest challenges schools face. Due to lack of support or too much interference from the parent the academic learning process of the student is disturbed and delayed. This also puts a lot of stress on the teacher trying to support the student in achieving to the best of his or her abilities as well as managing the parents on the side. The purpose of this study was to investigate how 1) different parenting styles deliver different results and if that...

  4. Impaired IQ and Academic Skills in Adults Who Experienced Moderate to Severe Infantile Malnutrition: A Forty-Year Study

    Waber, Deborah P.; Bryce, Cyralene P.; Girard, Jonathan M.; Zichlin, Miriam; Fitzmaurice, Garrett M.; Galler, Janina R.

    2013-01-01

    Objectives To evaluate IQ and academic skills in adults who experienced an episode of moderate to severe infantile malnutrition and a healthy control group, all followed since childhood in the Barbados Nutrition Study. Methods IQ and academic skills were assessed in 77 previously malnourished adults (mean age=38.4 years; 53% male) and 59 controls (mean age=38.1 years; 54% male). Group comparisons were carried out by multiple regression and logistic regression, adjusted for childhood socioeconomic factors. Results The previously malnourished group showed substantial deficits on all outcomes relative to healthy controls (p<0.0001). IQ scores in the Intellectual Disability range (< 70) were 9 times more prevalent in the previously malnourished group (OR=9.18; 95% CI=3.50-24.13). Group differences in IQ of approximately one standard deviation were stable from adolescence through mid-life. Discussion Moderate to severe malnutrition during infancy is associated with a significantly elevated incidence of impaired IQ in adulthood, even when physical growth is completely rehabilitated. An episode of malnutrition during the first year of life carries risk for significant lifelong functional morbidity. PMID:23484464

  5. Non Infectious Complications Related to Blood Transfusion: An 11 year Retrospective Analysis in a Tertiary Care Hospital.

    2016-09-01

    In India transmission of transfusion transmissible infections (TTI) has shown a relative decrease as a result of mandatory screening of donated blood for TTI's. However, reducing the incidence of non infectious complications poses a major challenge, mainly due to the fact that a number of adverse reactions go unreported. Blood transfusion reaction, can be categorized based on the time interval between transfusion of blood products and the presentation of adverse reactions as acute i.e. those presenting during or within 24 h and as delayed i.e. those presenting anytime after 24 h. Transfusion reactions can further be classified as immune and non immune or infectious and non infectious based on the pathophysiology. In this retrospective study which was undertaken with an aim to determine the type and frequency of non infectious complications due to transfusion of blood and blood products recorded the incidence of febrile non hemolytic transfusion reactions (FNHTR) 51.40 %, allergic reactions 40.14 %, non immune hemolytic reactions 4.22 %, hypothermia 2.81 %, anaphylaxis 0.70 % and iron overload 0.70 %. FNHTR which was found to be the most common complication in this study can certainly be minimized, if not completely eliminated by adopting a policy of universal leucodepletion, the implementation of which solely depends on the financial and infrastructure resources available. This study also reiterates the importance of hemovigilance as a tool to improve the safety of blood transfusion. PMID:27429521

  6. Major complications of radiotherapy in cancer of the oral cavity and oropharynx. A 10 year retrospective study

    In an attempt to determine the late effects and associated morbidity of radiotherapy on normal tissue, patients with squamous carcinoma of the oral cavity and oropharynx were retrospectively reviewed. Between 1964 and 1975, 569 patients with cancer of the floor of the mouth, oral tongue, tonsil, and retromolar trigone region of the anterior faucial pillar had their primary lesions treated by radiotherapy alone for cure. One hundred twenty-eight of the patients were evaluable for this study. Bone and soft tissue morbidity were graded according to the late radiation scoring scheme of the radiation therapy oncology group of the European Organization on Research and Treatment of Cancer, tallying only grade 4 changes. Patients were further classified according to site of tumor, age, sex, tumor stage, histologic grade, and dental status--none of which had a positive correlation with complications. Of 31 evaluable patients with cancer of the floor of the mouth (median follow-up 136 months), 71 percent (22 of 31 patients) had at least one complication involving bone (osteonecrosis, pathologic fracture) or mucus membrane (ulcer). Sixty-one percent (25 of 41 patients) with primary cancer of the oral tongue had grade 4 sequelae (median follow-up 112 months). In 26 patients with cancer of the tonsil, 13 (50 percent) had grade 4 sequelae (median follow-up 113 months). This included 11 patients with clinical and radiographic evidence of osteonecrosis, 6 of whom required mandibulectomy. Patients with cancer of the retromolar trigone region of the anterior faucial pillar fared the best (median follow-up 122 months). Late sequelae were noted in 40 percent (12 of 30 patients). The morbidity attendant to cure by radiotherapy included at least one significant complication of bone or soft tissue in 40 to 70 percent of the patients, depending on the location of the primary tumor. There was also a positive correlation with dose of radiation received

    The purpose of this retrospective clinical study was to evaluate the survival rate (i.e. SVR – fixtures still in place at the end of the observation period) and success rate (i.e. SCR - bone resorption around implant neck) of an implant system characterized by cylindrical and tapered implants, both types of implant being equipped with a conical connection with an internal octagon (COC), both implant types having a 1.8 mm smooth neck, positioned above the bone crest level. A total of 65 subjects received 215 COCs between January 1996 and October 2011. All COCs were placed and restored by three experienced dental surgeons. The mean follow-up was 84±44 months. The patients involved in the study were both male (30) and female (35), of whom 30 were smokers (less than 20 cigarettes/day) and none was diabetic. The implants differed in terms of diameter and length, and were inserted both in the mandible (97) and in the maxilla (118). Sixty-seven implants were single tooth rehabilitations, and 148 prosthetic bridges. Fourteen had guided bone regeneration (GBR), and 10 were placed in post-extractive sites. Forty of the implants were provided with passing-screw abutments and 175 with full-screw abutments. The data were analyzed using descriptive statistics. None of the implants failed before prosthetic restoration, resulting in an SVR=100% after loading. The radiographic and clinical data revealed well-maintained, hard and soft tissue around the COCs, with an SCR=92.6%. Cox regression analyses did not detect any variables with statistical impact on the clinical outcome. In conclusion, Shiner XT implants are reliable tools for oral rehabilitation. PMID:27469549

    BACKGROUND Retinopathy is a serious complication related to prematurity and a leading cause of childhood blindness. The aggressive posterior form of retinopathy of prematurity (APROP) has a worse anatomical and functional outcome following laser therapy, as compared with the classic form of the disease. The main outcome measures are the APROP regression rate, structural outcomes, and complications associated with intravitreal bevacizumab (IVB) versus laser photocoagulation in APROP. MATERIAL AND METHODS This is a retrospective case series that includes infants with APROP who received either IVB or laser photocoagulation and had a follow-up of at least 60 weeks (for the laser photocoagulation group) and 80 weeks (for the IVB group). In the first group, laser photocoagulation of the retina was carried out and in the second group, 1 bevacizumab injection was administered intravitreally. The following parameters were analyzed in each group: sex, gestational age, birth weight, postnatal age and postmenstrual age at treatment, APROP regression, sequelae, and complications. Statistical analysis was performed using Microsoft Excel and IBM SPSS (version 23.0). RESULTS The laser photocoagulation group consisted of 6 premature infants (12 eyes) and the IVB group consisted of 17 premature infants (34 eyes). Within the laser photocoagulation group, the evolution was favorable in 9 eyes (75%) and unfavorable in 3 eyes (25%). Within the IVB group, APROP regressed in 29 eyes (85.29%) and failed to regress in 5 eyes (14.71%). These differences are statistically significant, as proved by the McNemar test (P<0.001). CONCLUSIONS The IVB group had a statistically significant better outcome compared with the laser photocoagulation group, in APROP in our series. PMID:27062023

    Objective The purpose of this study was to determine the prevalence of adverse drug reactions (ADRs) reported in emergency departments (EDs) and carry out a thorough characterization of these to assess preventability, seriousness that required hospitalization, subsequent 30-day mortality, and economic burden. Methods This was a retrospective cohort study of data from an active pharmacovigilance project at 32 EDs in the Lombardy region collected between January 1, 2010 and December 31, 2011. Demographic, clinical, and pharmacological data on patients admitted to EDs were collected by trained and qualified monitors, and deterministic record linkage was performed to estimate hospitalizations. Pharmacoeconomic analyses were based on Diagnosis-Related Group reimbursement. Results 8,862 ADRs collected with an overall prevalence rate of 3.5 per 1,000 visits. Of all ADRs, 42% were probably/definitely preventable and 46.4% were serious, 15% required hospitalization, and 1.5% resulted in death. The System Organ Classes most frequently associated with ADRs were: skin and subcutaneous tissue, gastrointestinal, respiratory thoracic and mediastinal, and nervous system disorders. The most common Anatomical Therapeutic Chemical classes involved in admissions were J (anti-infectives and immunomodulating agents), B (blood and blood-forming organs), and N (nervous system). Older age, yellow and red triage, higher number of concomitantly taken drugs, and previous attendance in ED for the same ADR were significantly associated with an increased risk of hospitalization. The total cost associated with ADR management was €5,184,270, with a mean cost per patient of €585. Fifty-eight percent of the economic burden was defined as probably/definitely preventable. Conclusion ADRs are a serious health/economic issue in EDs. This assessment provides a thorough estimation of their seriousness, preventability, and burden impact in a large population from a representative European region. PMID

    Full Text Available Acute Bacterial Meningitis (ABM is an important cause of death and long-term neurological disability. Recent Information on the relative frequency of the isolation and antibiotic susceptibility patterns of these pathogens is scarce in Ethiopia. This study was to document the microbial characteristics, the antibacterial sensitivity pattern, and seasonal variation of community acquired acute bacterial meningitis. The study was retrospective, conducted at university of Gondar referral hospital, serving the rural population of the northwest parts of Ethiopia. A total of three thousand and eighty five cerebrospinal fluid specimens submitted to the bacteriology laboratory for culture and antibiotic susceptibility patterns in a period between January 2006 and December 2010. Analysis of extracted data was performed using SPSS statistical software (Version 17. The etiological agent had been identified in 120 (3.8% of the total 3,085 CSF samples by culture. Thirty-nine (32.5% of them were infants below the age of 12 months. S. pneumoniae was the predominant pathogen accounting for 52 (43.3% of the cases. Whereas N. meningitidis and H. influenzae accounted for 27(22.5%, and 12(10%, respectively. Other gram negative bacilli and S. aureus were isolated from 21(17.2%, and 11(9.2% cases, respectively. Among gram positive organisms S.pneumoniae showed a high level of drug resistance against co-trimoxazole 44(84.3%. Among gram negative bacteria, N.meningitidis was found to be resistant to co-trimoxazole in 25(92.5%. E. coli and salmonella spp. were found to be resistant to most antibiotics except ciprofloxacin. Multiple drug resistance was observed in 58.3% of the isolates. S. pneumoniae remains the major etiological agent of Community Acquired Acute Bacterial Meningitis (CAABM both in adults and children in the study area. 5.7% of S. pneumoniae were resistances to penicillin. Further research should focus on preventable aspects CAABM of, especially pneumococcal

    Objective To investigate the prevalence and trends of sensitisation to common aeroallergens among outpatients with allergic rhinitis (AR) in Guangzhou, China, over the past decade. Design A retrospective study; linear-by-linear association and simple linear regression were used to determine the trends in the prevalence of aeroallergen sensitisation. Setting One grade-A hospital in Guangzhou, the largest city in southern China. Participants A total of 5486 patients (2297 males and 2489 females) who visited the ear, nose and throat outpatient clinic, from January 2005 to December 2014, were enrolled. All patients who presented with nasal hyper-reactive symptoms and who completed serological allergy testing, measuring specific IgE (sIgE) in the serum, were included. Among them, 4085 participants (2269 males and 1816 females) were diagnosed as being patients with AR. Outcome measures Prevalence and trends of sensitisation to various types of aeroallergens were assessed. Results The overall prevalence of sIgE-mediated sensitisation to aeroallergens in these patients with AR were as follows: 84.4% for house dust mites (HDMs), 23.4% for pet allergens, 21.1% for cockroaches, 9.1% for mould allergens, 7.7% for tree pollen and 6.0% for weed pollen. When all patients with nasal hyper-reactivity were stratified by decade of age, increasing age was associated with a decrease in sIgE positivity by ∼5.13% (95% CI −7.28% to −2.98%, p<0.01). Within the past decade, the prevalence of sensitisation to pet allergens in patients with AR increased at an annual rate of 1.3% (95% CI 0.85% to 1.67%, p<0.01). Conclusions This study demonstrated that HDMs comprised the most common aeroallergen in Guangzhou. The prevalence of sensitisation to aeroallergens decreased with increasing age. During the past decade, the prevalence of sensitisation to pet allergens showed an upward trend, suggesting an urgent need for its prevention and treatment. PMID:27188812

  15. Fistula Rate after primary palatal repair with intravelarveloplasty: a retrospective three-year audit of six units (NorCleft) in the UK.

    Moar, Kanwalraj K; Sweet, Christopher; Beale, Victoria

    2016-07-01

    Our aim was to evaluate the rate of fistulation after one-stage palatal repair by intravelarveloplasty in the NorCleft Cleft Services (Scotland and Northern England), this being a primary outcome measure after repair of a cleft palate. We designed a retrospective, three-year clinical audit of six cleft units in the UK, and retrospectively reviewed the casenotes of babies with cleft palate born in 2006-2008 who were treated by intravelarveloplasty. We recorded type of cleft and procedure, including lateral relieving incisions, and our main outcome measure was the presence of a fistula behind the incisive foramen at 3 years of age, or a history of repair of a fistula. A total of 743 patients had cleft palates, but 69 (9%) were excluded (because they had not been operated on, or had not been reviewed by the age of 3 years, or their records were unavailable). A total of 626 patients had had a Sommerlad intravelarveloplasty repair, and 48 had had mixed procedures including Veau-Wardill-Kilner, Furlow, or two-stage repairs, and were not studied further. Eighty-seven (14%) who had had intravelarvoloplasty had a fistula behind the incisive foramen. There was no significant difference in age at time of repair between those who developed a fistula and those who did not (p=0.65). The fistula rate of 14% is comparable with that of Sommerlad. The fistula rate was higher in patients who had had lateral releasing incisions (58/275, 21%) or who had bilateral cleft palate (16/63, 25%). To our knowledge this is the largest review of the fistula rate in patients who had primary palatal repair using the intravelarveloplasty technique in the UK, and shows significant correlation between lateral releasing incisions and formation of a fistula, except in the unilateral cleft lip and palate group (p=0.12).

    Full Text Available Abstract Background Dupuytren's disease (DD is a hand disorder mainly among the northern population. In contrast it is rare in the mediterranean population. Therefore typical habits and dietetic influences have been discussed as well as genetic predisposition. Still, since the first description by Dupuytren in 1834 only little is known about the etiology and pathogenesis of this disease. Some hints were found for a higher prevalence among people with diabetes, alcohol abuse or smoking. Also, intensive manual work or hand injuries have been discussed to have an influence on DD. To our knowledge this is the largest retrospectively evaluated series of symptomatic patients published to date. The study includes patients from the last 50 years. It was performed to show possible correlations between DD and typical risk factors such as diabetes, alcohol consumption, and smoking. Methods We retrospectively analysed all patient records with DD documented between 1956 and 2006 in the Surgical University Hospital in Erlangen. Data acquisition was conducted by reviewing the medical records from 1956 to 2006 including data from all patients who were surgically treated because of DD. Results We reviewed 2579 male and 340 female surgically treated patients with DD. More than 80% of the patients were between 40 and 70 years old. In 28.9% only the right hand was effected by DD, in 25.3% only the left hand and in 45.8% both hands. In 10.3% of all Patients suffered from Diabetes mellitus. Statistical analysis revealed no significant correlation between diabetes, alcoholism or smoking on the degree of DD in our patients. Conclusion Most data are consistent with previously published results from smaller, comparable retrospective studies with regard to right- or left handedness. We could not confirm a statistically significant correlation of DD with diabetes mellitus, severe alcohol consumption, heavy smoking or epilepsy and the stage of the disease as described in

  19. Improving year-end transfers of care in academic ambulatory clinics: a survey of pediatric resident physician perceptions

    Carlos F. Lerner

    2012-05-01

    Full Text Available Background: In resident primary care continuity clinics, at the end of each academic year, continuity of care is disrupted when patients cared for by the graduating class are redistributed to other residents. Yet, despite the recent focus on the transfers of care between resident physicians in inpatient settings, there has been minimal attention given to patient care transfers in academic ambulatory clinics. We sought to elicit the views of pediatric residents regarding year-end patient handoffs in a pediatric resident continuity clinic.Methods: Residents assigned to a continuity clinic of a large pediatric residency program completed a questionnaire regarding year-end transfers of care.Results: Thirty-one questionnaires were completed out of a total 45 eligible residents (69% response. Eighty seven percent of residents strongly or somewhat agreed that it would be useful to receive a written sign-out for patients with complex medical or social issues, but only 35% felt it would be useful for patients with no significant issues. Residents more frequently reported having access to adequate information regarding their new patients’ medical summary (53% and care plan (47% than patients’ functional abilities (30%, social history (17%, or use of community resources (17%. When rating the importance of receiving adequate sign-out in each those domains, residents gave most importance to the medical summary (87% of residents indicating very or somewhat important and plan of care (84%. Residents gave less importance to receiving sign-out regarding their patients’ functional abilities (71% social history (58%, and community resources (58%. Residents indicated that lack of access to adequate patient information resulted in additional work (80%, delays or omissions in needed care (56%, and disruptions in continuity of care (58%.Conclusions: In a single-site study, residents perceive that they lack adequate information during year-end patient transfers

  20. A Cohort-based Learning Community Enhances Academic Success and Satisfaction with University Experience for First-Year Students

    Corey A. Goldman

    2012-12-01

    Full Text Available Assessment of a successful cohort-based learning communities program for first-year undergraduate students shows that students in the program perform better academically and also report a higher level of satisfaction with their university experience than students who are not in the program. Students enrolled in arts and science at the University of Toronto, who take several large-enrolment courses in their first year, may optionally participate in the First-Year Learning Communities (FLC program, designed to assist with the academic and social transition from high school to university. In this Freshman Interest Group model of learning community, the curriculum across the clustered courses is not linked. The FLC program was assessed over a five-year period, using student academic records and self-reported survey data. This paper also provides details on program design and implementation.L’évaluation d’un programme de communautés d’apprentissage fondées sur les cohortes pour les étudiants de première année du premier cycle qui a obtenu du succès montre que ceux qui sont inscrits à ce programme ont de meilleurs résultats scolaires et sont plus satisfaits de leur expérience universitaire que les autres.

  3. The utilisation and diagnostic yield of radiological imaging in a specialist functional GI disorder clinic: an 11-year retrospective study

    The term functional gastrointestinal disorders (FGID) describes various aggregations of chronic gastrointestinal (GI) symptoms not explained by identifiable organic pathology; accordingly, their diagnosis rests on symptom-based criteria and a process of exclusion. Evidence is lacking on the appropriate use of abdominal imaging studies (AIS) in FGIDs. We investigated the utilisation of AIS (site, modality, diagnostic yield/significance) at a tertiary FGID clinic over an 11-year period. Of 1,621 patients, 507 (31 %; 67.5 % women, mean age 43.9 ± 17.37 years) referred from primary care had 997 AIS (1.7 per patient): ultrasonography (US) 36.1 %, fluoroscopy (FLS) 28.8 %, computed tomography (CT) 19.6 %, plain radiography (PR) 13.5 %, nuclear medicine (NM) 1 %. Of the 997 AIS, 55.6 % (554/997) were normal. Of the AIS with positive findings, 9.9 % (62/625) were deemed 'probably significant' and 14.7 % (92/625) 'significant'. Of the CT and FLS studies, 12.3 % and 13.6 %, respectively, yielded 'significant' abnormalities compared to 2.2 % of the US studies and 2.1 % of the PR studies. CT identified five of seven neoplasms, associated with male sex, increasing age and symptom onset after age 50 years. This study confirmed low use of AIS in tertiary FGID clinics and a high proportion of normal studies. Barium swallow/meal and CT were more likely to identify 'probably significant' or 'significant' findings, including neoplasms. (orig.)

    Suppan, Catherine A; Bae, Donald S; Donohue, Kyna S; Miller, Patricia E; Kocher, Mininder S; Heyworth, Benton E

    2016-07-01

    The purpose of this study was to examine institutional trends in the volume of clavicle fractures in children and adolescents. Medical records were retrospectively reviewed to identify patients aged 10-18 years treated for a clavicle fracture between 1999 and 2011 at a single tertiary-care pediatric hospital. There were significant increases in the number of clavicle fractures seen annually, of midshaft clavicle fractures, and of midshaft clavicle fractures treated operatively. The percentage of midshaft clavicle fractures treated with fixation also increased significantly. The volumes of clavicle fractures and midshaft clavicle fractures treated operatively appear to be increasing. Despite a lack of evidence-based support, the frequency of fixation of midshaft clavicle fractures appear to be increasing in the pediatric population. PMID:26990058

  9. First-year students' conflicts during their construction of an academic identity in English as a foreign language : implementing cultural-historical activity theory

    Oliva-Girbau, Angels

    2011-01-01

    This paper constructs a theoretical framework that views academic writing from a context-based perspective. The shift from text to context results from implementating the concept of activity system into the academic community, envisioning academia as the sum of the interactions among its components (users, tools, goals and results), which was applied into an instrumental English course for first-year students through reflective activities that promoted awareness and discussion of the componen...

    Ásta Björg Magnúsdóttir 1989

    2013-01-01

    An important topic in psychology is the prediction of academic achievement. Studies have shown that there are many different psychological and cognitive components that influence academic achievement. Cognitive ability tests that measure verbal comprehension, spatial ability, working memory span and more have been shown to relate to different skills in the academic environment. Anxiety is another component that has been shown to correlate strongly with academic achievement and especially on s...

The mean age was 32.69 ± 17.2 7, and males were more commonly affected. Conclusion: A marked geographic and demographic variation was observed in the relative frequency of various odontogenic tumors in the South Indian population which stresses upon the influence of genetic and/or environmental (epigenetic factors on tumor pathogenesis.

  17. A unique trend of murder-suicide in the Jamnagar region of Gujarat, India (a retrospective study of 5 years).

    Gupta, B D; Gambhir Singh, O

    2008-05-01

    Jamnagar region, Gujarat state, enjoys a relatively low incidence of homicide in India. In the 5 year period from 2000 to 2004, 8 mothers committed 13 murders involving 3 male and 10 female victims and in every case it was followed by suicide of the assailant mothers. During the study the annual incidence of murder-suicide was about 1.8 cases. All the assailants were mothers and the victims were their small children in the age group of 6 months to 7 years. Five incidents took place in rural areas and three in urban areas. It was prevalent only in low socio-economic families. Methods both for killing and suicide were either burning or drowning. All the mothers were legally married and living with the family. Family and family related matters were the main motives for killing. In one case there was history of depression of the mother due to her previous miscarriage. Alcohol consumption or drug abuse was not seen even in a single case. All cases fell in the altruistic category of filicide-suicide. PMID:18423359

    2009-03-01

    Full Text Available Objective: The aim of the present study was to investigate the demographic and pathological aspects of adenoid cystic carcinomas (ACC in an Iranian sample based on a 20-year archive review.Materials and Methods: In this descriptive study, tumors of the head and neck registered between 1980 and 2000 were evaluated and cases of ACC were selected. Patients’ medical records and pathology reports were reviewed. Variables such as age, sex, duration of disease,symptoms, site of tumor involvement and tumor diameter as well as pathologic features were recorded. Analysis was performed using chi-square and t-tests; P<0.05 was considered as the level of significance.Results: ACC was the most common malignant tumor followed by mucoepidermoid carcinoma and adenocarcinoma NOS. A total of 120 ACCs were found, of which 50.8% occurred in females and 49.2% in males. Patients’ ages ranged from 5 to 90 with a mean of 49.2 (SD=15.9 years. In 60.9% of cases, minor salivary glands were involved and the palate was the most common site. The greatest tumor diameter was between 2-15cm with a mean of 4.6 cm (SD=2.9. The most prevalent histologic appearance was cribriform, followed by tubular pattern. No significant relation was observed between lymph node metastasisand patients’ age, sex, disease duration, greatest tumor diameter and site of involvement.Conclusion: Our findings were relatively similar to other reports from different parts of the world. Further analytic and case-control studies are recommended to gain a better understanding of different aspects of ACC.

  1. Secular Variation Across the Oceans: a Retrospective Study from 35 Years of Shipboard Total Field Measurements in the NE Atlantic

    Williams, C. A.; Verhoef, J.; Macnab, R.

    1992-01-01

    This is a pilot study to determine whether secular variation information can be retrieved from underway shipboard total field measurements with sufficient accuracy to complement geomagnetic data from land-based observatories. Applying the various new techniques described in this report, we extracted values of the total field at 42,677 crossovers or ship track intersection points contained in data sets collected between 18 degrees N and 50 degress N in the NE Atlantic, and extending temporally from 1955 to 1990. We used an edited subset of these total field values to derive the secular variation at 30,140 different locations in the study area, and compared the results with DGRF secular variation over the study area, calculated at 5 year intervals. The derived and DGRF values agree well, showing that indeed marine data can be a source for secular variations. However the analysis demonstrated that due to inherent noise in the marine data, only minor improvements on the DGRF values for the secular variation can be achieved.

  2. Charges associated with pediatric head injuries: A five-year retrospective review of 41 pediatric hospitals in the US.

    Charles Edward McConnel

    2013-01-01

    Full Text Available BACKGROUND: Brain injuries are a significant public health problem, particularly among the pediatric population. Brain injuries account for a significant portion of pediatric injury deaths, and are the highest contributor to morbidity and mortality in the pediatric and young adult populations. Several studies focus on particular mechanisms of brain injury and the cost of treating brain injuries, but few studies exist in the literature examining the highest contributing mechanisms to pediatric brain injury and the billed charges associated with them. METHODS: Data were extracted from the Pediatric Health Information System (PHIS from member hospitals on all patients admitted with diagnosed head injuries and comparisons were made between ICU and non-ICU admissions. Collected data included demographic information, injury information, total billed charges, and patient outcome. RESULTS: Motor vehicle collisions, falls, and assaults/abuse are the three highest contributors to brain injury in terms of total numbers and total billed charges. These three mechanisms of injury account for almost $1 billion in total charges across the five-year period, and account for almost half of the total charges in this dataset over that time period. CONCLUSION: Research focusing on brain injury should be tailored to the areas of the most pressing need and the highest contributing factors. While this study is focused on a select number of pediatric hospitals located throughout the country, it identifies significant contributors to head injuries, and the costs associated with treating them.

  3. Rising trends of HCV infection over a period of 4 years among blood donors in central India: A retrospective study

    Alok Kumar

    2010-10-01

    Full Text Available Objective: The aim of the study was to find out the sero-prevalence of Hepatitis C infection among blood donors. Materials and Methods: All collected blood bags were screened for anti-hepatitis C virus antibodies (HCV Ab; MicroELISA 3rd generation, J. Mitra during the study period of 4 years and data were analyzed. Results: A total of 28621 blood donors were screened for transfusion transmissible infections (TTIs in which 80 donors were positive for Hepatitis C infection, constituted 11% of total sero-reactive donors. In 2009, only 10 cases were sero-reactive while in 2012, 36 cases were sero-reactive for Hepatitis C infection. Conclusions: Hepatitis C infection among blood donors are in rising trends in this study area. Voluntary donors are safer than replacement donors as they have very low sero-prevalence. As these blood donors represent the highly selective community of a general population in most of the countries. So the actual sero-prevalence of hepatitis C infection may be more in the general population. Promoting HCV screening, voluntary blood donation, diagnosis and treatment among blood donors are very important measures to control the transmission of HCV infection, decrease sero-reactive cases and ensure safe blood collection.

  4. Family, peer, and neighborhood influences on academic achievement among African-American adolescents: one-year prospective effects.

    Gonzales, N A; Cauce, A M; Friedman, R J; Mason, C A

    1996-06-01

    Using a 1-year prospective design, this study examined the influence of family status variables (family income, parental education, family structure), parenting variables (maternal support and restrictive control), peer support, and neighborhood risk on the school performance of 120 African American junior high school students. In addition to main effects of these variables, neighborhood risk was examined as a moderator of the effects of parenting and peer support. Family status variables were not predictive of adolescent school performance as indexed by self-reported grade point average. Maternal support at Time 1 was prospectively related to adolescent grades at Time 2. Neighborhood risk was related to lower grades, while peer support predicted better grades in the prospective analyses. Neighborhood risk also moderated the effects of maternal restrictive control and peer support on adolescent grades in prospective analyses. These findings highlight the importance of an ecological approach to the problem of academic underachievement within the African American Community. PMID:8864209

  5. Effect of electronic patient record use on mortality in End Stage Renal Disease, a model chronic disease: retrospective analysis of 9 years of prospectively collected data

    Lorch Jonathan A

    2007-11-01

    Full Text Available Abstract Background In chronic disease, health information technology promises but has yet to demonstrate improved outcomes and decreased costs. The main aim of the study was to determine the effects on mortality and cost of an electronic patient record used in daily patient care in a model chronic disease, End Stage Renal Disease, treated by chronic maintenance hemodialysis. Dialysis treatment is highly regulated, and near uniform in treatment modalities and drugs used. Methods The particular electronic patient record, patient-centered and extensively coded, was used first in patient care in 3 dialysis units in New York, NY in 1998, 1999, and 2000. All data were stored "live"; none were archived. By December 31, 2006, the patients had been treated by maintenance hemodialysis for a total of 3924 years. A retrospective analysis was made using query tools embedded in the software. The United States Renal Data System dialysis population served as controls. In all there were 1790 patients, with many underlying primary diseases and multiple comorbid conditions affecting many organ systems. Year by year mortality, hospital admissions, and staffing were analyzed, and the data were compared with national data compiled by the United States Renal Data System. Results Analyzed by calendar year after electronic patient record implementation, mortality decreased strikingly. In years 3–9 mortality was lower than in years 1–2 by 23%, 48%, and 34% in the 3 units, and was 37%, 37%, and 35% less than that reported by the United States Renal Data System. Clinical staffing was 25% fewer per 100 patients than the national average, thereby lowering costs. Conclusion To our knowledge, this is the first demonstration that an electronic patient record, albeit of particular design, can have a favorable effect on outcomes and cost in chronic disease. That the population studied has many underlying diseases affecting all organ systems suggests that the electronic

    Background Cervical arthroplasty is indicated to preserve cervical motion and prevent accelerated adjacent segment degeneration.Whether accelerated adjacent segment degeneration is prevented in the long term is unclear.This trial compared adjacent segment degeneration in Bryan disc arthroplasty with that in anterior cervical decompression and fusion five years after the surgery.Methods We studied patients with single level degenerative cervical disc disease.The extent of adjacent segment degeneration was estimated from lateral X-rays.Results Twenty-six patients underwent single level Bryan disc arthroplasty and twenty-four patients underwent single level anterior cervical decompression and fusion.All patients were followed up for an average of sixty months.In the Bryan arthroplasty group,nine(17.6%)segments developed adjacent segment degeneration,which was significantly lower than that(60.4%)in the anterior cervical decompression and fusion group.Eleven segments in the Bryan arthroplasty group developed heterotopic ossification according to McAfee's classification and two segments had range of motion less than 2°.In the heterotopic ossification group,four(19.5%)segments developed adjacent segment degeneration,similar to the number in the non-heterotopic ossification group(16.7%).Adjacent segment degeneration rate was 50% in gradeⅣ?group but 11.8% in gradeⅡ?to Ⅲ.Conclusions Adjacent segment degeneration was accelerated after anterior cervical decompression and fusion.However,Bryan disc arthroplasty avoided accelerated adjacent segment degeneration by preserving motion.Patients with gradeⅣ?heterotopic ossification lost motion,and the rate of adjacent segment degeneration was higher than that in patients without heterotopic ossification.

    An international study under the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) was performed to assess radiological impact of the nuclear accident at the Fukushima-Daiichi Nuclear Power Station (FDNPS) on the marine environment. This work constitutes the first international assessment of this type, drawing upon methodologies that incorporate the most up-to-date radioecological models and knowledge. To quantify the radiological impact on marine wildlife, a suite of state-of-the-art approaches to assess exposures to Fukushima derived radionuclides of marine biota, including predictive dynamic transfer modelling, was applied to a comprehensive dataset consisting of over 500 sediment, 6000 seawater and 5000 biota data points representative of the geographically relevant area during the first year after the accident. The dataset covers the period from May 2011 to August 2012. The method used to evaluate the ecological impact consists of comparing dose (rates) to which living species of interest are exposed during a defined period to critical effects values arising from the literature. The assessed doses follow a highly variable pattern and generally do not seem to indicate the potential for effects. A possible exception of a transient nature is the relatively contaminated area in the vicinity of the discharge point, where effects on sensitive endpoints in individual plants and animals might have occurred in the weeks directly following the accident. However, impacts on population integrity would have been unlikely due to the short duration and the limited space area of the initially high exposures. Our understanding of the biological impact of radiation on chronically exposed plants and animals continues to evolve, and still needs to be improved through future studies in the FDNPS marine environment.

    Full Text Available A survey was undertaken aiming to obtain an overview of ocular and periocular lesions diagnosed in domestic mammals over a period of 50 years in a veterinary pathology diagnostic laboratory in the Central Region of the State of Rio Grande do Sul, Brazil. In this lab, 33,075 histophatological exams had been performed over the period surveyed, of which 540 (1.6% concerned ocular and periocular lesions. For various reasons ninety specimens were excluded from the study and the remaining 450 consisted of samples from dogs (53.5%, cattle (28.2%, cats (11.1%, horses (5.1% sheep (1.3%, rabbits (0.4%, and pig (0.2%. The eyelids were the most prevalent (248/450 site of lesions in each of the species studied, followed by third eyelid (73/450, and conjunctiva (27/450. In dogs (241 samples lesions in sebaceous glands (including Meibomian glands were the most common findings (75/241, followed by melanocytic tumors (52/241 and nonspecific conjunctivitis (13/241. Squamous cell neoplasms, both benign and malignant, were relatively common. In cattle, anatomical sites affected by ocular and periocular lesions, in decreasing order of frequency, were eyelid, cornea and third eyelid. Squamous cell carcinoma (SCC alone accounted for 80.3% of all diagnoses, while all neoplastic lesions made up for 85.0% of the lesions diagnosed in cattle. Neoplasia accounted for most of the lesions diagnosed in cats (39/50 cases; all of these were malignant, and SCC, hemangiosarcoma and fibrosarcoma were the most common types diagnosed.

    Islam, Mohammed Nasimul; See, Khoo Lay; Ting, Lai Chin; Khan, Jesmine

    2006-01-01

    This paper investigates the pattern of sexual offence cases attended at the One Stop Crisis Center (OSCC) of the Accident and Emergency Department, Hospital Universiti Sains Malaysia (HUSM), Kelantan. A total of 439 reported sexual offence cases were examined over a period of 4 years from 2000 to 2003. Sexual offence constituted by male partner or boyfriend in 18.9%, by relatives in 27.3% and by "others" in 53.8% of cases. Only 0.7% of victims did not attempt to lodge a police report. There is a significant relationship between occupation and the risk of experiencing sexual violence. Students were mostly targeted by the perpetrator throughout the study period. Among the offences, rape cases were the highest in number, among those who attended at the OSCC, HUSM with a total of 72.7%; followed by 27.3% of incest; 26.4% of child sexual abuse; 4.8% of sodomy and lastly 1.6% of gerontophilia cases. Only 70% of the specimens obtained from sexual offences victims were sent for laboratory analysis. The result remained negative in 82.4% specimens and thus the laboratory analysis result is merely functioning as a supportive evidence for sexual offence cases attended at OSCC. The studies showed that most of the sexual assault perpetrators were known to the victims. The place of crime was also known to the perpetrators. Health sectors of various levels should be working in conjunction to promote a societal changes to improve more of the women's right and thus to reduce the violence crime. PMID:22589588

    2016-06-01

    Both alcohol abuse and liver cirrhosis are known risk factors for various cancers. This article was aimed to assess the long-term risk of malignancies among patients with severe alcoholic liver disease (ALD), i.e., alcoholic liver cirrhosis and alcoholic hepatitis. A cohort of 8,796 male and 3,077 female ALD patients from 1996 to 2012 was identified from the Finnish National Hospital Discharge Register. This nationwide cohort was combined with the data from the Finnish Cancer Registry for incidence of malignancies during the years 1996-2013. The cancer cases diagnosed were compared with the number of cancers in the general population. The number of malignancies in our cohort was 1,052 vs. 368 expected. There was statistically significant excess of cancers of the liver, (standardized incidence ratio [SIR] 59.20; 95% CI 53.11-65.61), pancreas (SIR 3.71; 95% CI 2.72-4.94), pharynx (SIR 9.25; 95% CI 6.05-13.56), mouth (SIR 8.31; 95% CI 4.84-13,29), oesophagus (SIR 7.92; 95% CI 5.49-11.07), tongue (SIR 7,21; 95% CI 3.60-12.89), larynx (SIR 5.20; 95% CI 2.77-8.89), lung (SIR 2.77; 95% CI 2.27-3.32), stomach (SIR 2.76; 95% CI 1.79-4.07), kidney (SIR 2.69; 95% CI 1.84-3.79) and colon (SIR 2.33; 95% CI 1.70-3.11). There was no decreased risk of any cancer among ALD patients. Severe ALD is associated with markedly increased risk of malignancies. The risk is especially high for hepatocellular carcinoma, but also significantly increased for cancers of the upper aerodigestive tract, pancreas and kidneys, and warrants cancer surveillance in selected cases.

  12. The clinical characteristics and direct medical cost of influenza in hospitalized children: a five-year retrospective study in Suzhou, China.

    Tao Zhang

    Full Text Available BACKGROUND: There have been few studies on children hospitalized with influenza published from mainland China. We performed a retrospective review of medical charts to describe the epidemiology, clinical features and direct medical cost of laboratory-proven influenza hospitalized children in Suzhou, China. METHODS: Retrospective study on children with documented influenza infection hospitalized at Suzhou Children Hospital during 2005-2009 was conducted using a structured chart review instrument. RESULTS: A total of 480 children were positive by immuno-fluorescent assay for influenza during 2005-2009. The hospitalizations for influenza occurred in 8-12 months of the year, most commonly in the winter with a second late summer peak (August-September. Influenza A accounted for 86.3%, and of these 286 (59.6% were male, and 87.2% were 60 months old had shorter hospital stay (OR = 0.45; children with oxygen treatment tended to have longer hospital stays than those without oxygen treatment (OR = 2.14. The mean cost of each influenza-related hospitalization was US$ 624 (US$ 1323 for children referred to ICU and US$ 617 for those cared for on the wards. High risk children had higher total cost than low-risk patients. CONCLUSION: Compared to other countries, in Suzhou, children hospitalized with influenza have longer hospital stay and higher percentage of pneumonia. The direct medical cost is high relative to family income. Effective strategies of influenza immunization of young children in China may be beneficial in addressing this disease burden.

    2013-12-01

    Two-year colleges play an important role in developing a competent and creative geoscience workforce, teaching science to pre-service K-12 teachers, producing earth-science literate citizens, and providing a foundation for broadening participation in the geosciences. The Supporting and Advancing Geoscience Education in Two-Year Colleges (SAGE 2YC) project has developed web resources for geoscience faculty on the preparation and support of students in two-year colleges (2YCs). Online resources developed from two topical workshops and several national, regional, and local workshops around the country focus on two main categories: Career Preparation and Workforce Development, and Supporting Student Success in Geoscience at Two-year Colleges. The Career Preparation and Workforce Development resources were developed to help faculty make the case that careers in the geosciences provide a range of possibilities for students and to support preparation for the geoscience workforce and for transfer to four-year programs as geoscience majors. Many two-year college students are unaware of geoscience career opportunities and these materials help illuminate possible futures for them. Resources include an overview of what geoscientists do; profiles of possible careers along with the preparation necessary to qualify for them; geoscience employer perspectives about jobs and the knowledge, skills, abilities and attitudes they are looking for in their employees; employment trends in sectors of the economy that employ geoscience professionals; examples of geotechnician workforce programs (e.g. Advanced Technological Education Centers, environmental technology programs, marine technician programs); and career resources available from professional societies. The website also provides information to support student recruitment into the geosciences and facilitate student transfer to geoscience programs at four- year colleges and universities, including sections on advising support before

    Objective: To prescribe and analyze the correlation of Dry Eye and Diabetes Mellitus Tip II, at Polyclinic of Specialties Nr. 2 Ophthalmology service, between May 2011 and June 2012.Methods:A total number of 223 patients diagnosed with Diabetes Mellitus Tip II underwent ocular examinations. 120 male and 103 female, aged from 24-73 years old. To confirm the presence of diabetes among these patients fasting blood glucose level was performed (normal limit < 110 mg/dL). History of disease, duration of diabetes, age, sex was obtained by reviewing the medical records and direct patient interview. Also the patients complains: tearing photophobia, red eye, itching ,foreign body sensation, blurred vision was recorded. From the study were excluded all conditions which affects the tear film stability and contact lens wearer.Results: 118 patients were diagnosed with Dry Eye Syndrome of varying degrees. 58 male/61 female. The diagnosis was made by heaving two or more positive tests performed as mentioned above, and referring to patients complains. Fourteen patients represent pinpoint corneal dye with fluorosceini, forty-six patients was positive to cotton swab test diminution of corneal sensitivity, eighty-nine patients was positive to Schirmmer test less than 10 mm, positive TBUT test less than 9 s was found to be the amount of seventy-one patients. Positive tear meniscus at inferior lid margin was found at fifty-six patients. Dry eye is a disorder of tear film because of tear deficiency or excessive tear evaporation which causes damage to the inter palpaberal ocular surface and is associated with symptoms of ocular discomfort. This ocular disorder is very common among general population with 28% of the adults having dry eye syndrome. Early diagnosis and timely treatment, complications as secondary microbial infection and corneal ulceration could be avoided. Conclusions: In our study the Dry Eye Syndrome showed to have a high correlation with Diabetes Mellitus Tip II (about 52

  7. The role biomedical science laboratories can play in improving science knowledge and promoting first-year nursing academic success

    Arneson, Pam

    The Role Biomedical Science Laboratories Can Play In Improving Science Knowledge and Promoting First-Year Nursing Academic Success The need for additional nursing and health care professionals is expected to increase dramatically over the next 20 years. With this in mind, students must have strong biomedical science knowledge to be competent in their field. Some studies have shown that participation in bioscience laboratories can enhance science knowledge. If this is true, an analysis of the role bioscience labs have in first-year nursing academic success is apposite. In response, this study sought to determine whether concurrent enrollment in anatomy and microbiology lecture and lab courses improved final lecture course grades. The investigation was expanded to include a comparison of first-year nursing GPA and prerequisite bioscience concurrent lecture/lab enrollment. Additionally, research has indicated that learning is affected by student perception of the course, instructor, content, and environment. To gain an insight regarding students' perspectives of laboratory courses, almost 100 students completed a 20-statement perception survey to understand how lab participation affects learning. Data analyses involved comparing anatomy and microbiology final lecture course grades between students who concurrently enrolled in the lecture and lab courses and students who completed the lecture course alone. Independent t test analyses revealed that there was no significant difference between the groups for anatomy, t(285) = .11, p = .912, but for microbiology, the lab course provided a significant educational benefit, t(256) = 4.47, p = .000. However, when concurrent prerequisite bioscience lecture/lab enrollment was compared to non-concurrent enrollment for first-year nursing GPA using independent t test analyses, no significant difference was found for South Dakota State University, t(37) = -1.57, p = .125, or for the University of South Dakota, t(38) = -0.46, p

    Ronika K. Power

    2011-10-01

    Full Text Available The Telemachus Ancient History Mentor Program (informally known as Tele’s Angels has been offering peer-led transition services to first-year students at Macquarie University since 2002. Tele’s Angels volunteer Mentors create a ‘learning community’ by providing their first-year colleagues with transition assistance, academic support and resources, and networking for and amongst students and staff. Individual mentoring is offered, as well as free peer-support services which focus on developing academic skills and building social networks. The program also focuses on student leadership – a key objective is that Mentors themselves are beneficiaries of all activities, embodying the program motto: “to give is to receive”. It is timely to report Tele’s Angels’ experiences to a wider audience and offer practical guidelines to those wishing to develop and implement subject-specific academic mentoring programs for first-year students in their own institutions.

  13. Retrospection of recent 30-year changes in the process of soil wind erosion in the Luanhe River Source Area of North China using Cesium-137

    The Luanhe River Source Area belongs to typical semi-arid, agro-pastoral ecotone of North China. It is very important for the prevention and treatment of soil erosion in North China to analyze and evaluate quantitatively the recent 30-year changes in the process of soil wind erosion in this area. Based on long field observations, soil samples from different depths in a representative wind-deposited soil profile in the Luanhe River Source Area were collected. Then the 137Cs activity of soil samples from different depths in the soil profile was determined using a GEM series HPGe (high-purity germanium) coaxial detector system (ADCAM-100), and their soil properties, such as the soil particle fraction and so on, were analyzed. According to the detected 137Cs activity of different depths, a continuous time sequence of the wind-deposited soil profile in the study area was established. Furthermore, through assumption on a soil relative wind erosion intensity index (SWEI), recent 30-year changes in the process of soil wind erosion in the Luanhe River Source Area were retrospected . The analysis results revealed that weaker soil wind erosion occurred in the study area from the 1970s to the early 1980s and from the late 1980s to the mid to late 1990s. Conversely, intense periods of soil wind erosion occurred in the mid-1980s and from the late 1990s to 2002.

    Full Text Available Abstract Background This study compared 1-year risk of psychiatric hospitalization and treatment costs in commercially insured patients with bipolar disorder, treated with aripiprazole, ziprasidone, olanzapine, quetiapine or risperidone. Methods This was a retrospective propensity score-matched cohort study using the Ingenix Lab/Rx integrated insurance claims dataset. Patients with bipolar disorder and 180 days of pre-index enrollment without antipsychotic exposure who received atypical antipsychotic agents were followed for up to 12 months following the initial antipsychotic prescription. The primary analysis used Cox proportional hazards regression to evaluate time-dependent risk of hospitalization, adjusting for age, sex and pre-index hospitalization. Generalized gamma regression compared post-index costs between treatment groups. Results Compared to aripiprazole, ziprasidone, olanzapine and quetiapine had higher risks for hospitalization (hazard ratio 1.96, 1.55 and 1.56, respectively; p Conclusions In commercially insured adults with bipolar disorder followed for 1 year after initiation of atypical antipsychotics, treatment with aripiprazole was associated with a lower risk of psychiatric hospitalization than ziprasidone, quetiapine, olanzapine and risperidone, although this did not reach significance with the latter. Aripiprazole was also associated with significantly lower total healthcare costs than quetiapine, but not the other comparators.

    The aim of this study was to retrospectively evaluate 75 implants inserted in vertically augmented bone at the time of or prior to implant placement after 1 to 6 years of prosthetic loading. The study included 21 patients (29 surgical sites). The vertical procedure was performed combining a titanium-reinforced expanded polytetrafluoroethylene membrane with autograft (7 sites), allograft (5 sites), or auto-xenograft (17 sites). Healing was uneventful in 24 surgical sites. Three sites showed premature exposure, and two sites presented an abscess. Two implants were lost, for a cumulative survival rate of 93.6%. Mean bone remodeling at 1, 2, 3, 4, 5, and 6 years was 0.34, 0.72, 1.04, 0.84, 0.56, and 0.61 mm, respectively. The implant success rate was higher with a simultaneous approach (82.5%) compared with a staged approach (66.8%). Implants surrounded by keratinized mucosa revealed a higher success rate (82.1%) than those without it (58.4%). PMID:25734704

    Full Text Available Background: Localization of germ cells tumors to the gonads is not uncommon and has been shown to possess good prognosis with appropriate treatment. Studies on the prevalence and histopathologic features of these tumors in Nigerians are, however, rare. This study was, therefore, aimed at determining the pattern of gonadal germ cell tumors (GGCTs in Benin and environs. Materials and Methods: This was a 20-year retrospective study conducted at the University of Benin Teaching Hospital 9-(UBTH, a tertiary health facility in Benin City. Data were obtained from the histopathology day book of the Department of Morbid Anatomy of the UBTH, and permission was obtained from the UBTH Ethics Committee protocol number ADM/E 22/A/VOL.VH/928 with results displayed in tables and figures. Results: Intratubular germ cell neoplasms (ITGN was the most common GGCT with about 33.3% of the total and was distributed within the fourth to fifth decades of life; benign cystic teratoma and choriocarcinoma were observed to have a low occurrence with 8.3% each found in age groups 11–20 and 21–30 years, respectively. The studied gonadal lesions were most frequent at the left testis and were predominantly premalignant forms. Conclusion: This was an index study on patterns of GGCTs in males in UBTH, and it showed that GGCTs in males were predominantly premalignant with ITGN as the most common type of testicular germ cell tumors.

    2008-06-01

    Full Text Available In an ever-changing world, competencies to process information efficiently are essential. However, several researchers indicate that graduates have limited abilities to solve complex problems in reality. In this paper, a possible solution to increase competences in effective searching, analysing and comparing information is provided. In a blended-learning environment, students had to share information before coming to class. The results of an analysis of four consecutive years of computersupported learning in a master-course indicate that students are willing to share information when conditions are favourable. In addition, a specific redesign of the task, control and social dimension let to increased knowledge sharing. Future research is necessary to assess whether this also has increased performance.

    Full Text Available In this study investigating international students’ perceptions of U.S. academic libraries, a qualitative method, photo-elicitation, is for the first time used to study how previous library experiences influence international students’ current perceptions of U.S. academic libraries. This study focuses on four dimensions of library service including access to information, affect of service, library as place, and personal control; these four dimensions are adapted from the LibQUAL+™, a web-based survey tool used among academic libraries for measuring users’ perceptions of library services.Five first-year graduate students from Taiwan were interviewed about how they perceived the library services of Center for Instructional Materials and Computing (CIMC, an academic library serving the students and faculty of School of Education at the University of Wisconsin, Madison. The findings of this study confirm the findings of previous studies both on international students’ in U.S. academic libraries and on photo-elicitation studies, and add empirical examples and insights for the claims in the limited body of research on international students in U.S. academic libraries.

  3. Five-year retrospective changes in hippocampal atrophy and cognitive screening test performances in very mild Alzheimer's disease: the Tajiri Project

    The medial temporal lobe, especially the hippocampus, is important for normal cognitive function, especially for memory, and is the region with the earliest and most extensive pathological changes in Alzheimer's disease (AD). We investigated the atrophic changes of the hippocampus over a 5-year period and its relation to cognitive screening test performances in normal elderly subjects, those with very mild AD, and patients with AD. Fifty-seven elderly subjects without a moderate or greater degree of cerebrovascular disease as shown by MRI were randomly selected from the town of Tajiri. Thirty-three subjects with a clinical dementia rating (CDR) of 0 (normal), 18 CDR-0.5 (very mild AD) subjects, and six CDR-1 and 2 (AD) subjects underwent MRI and the Mini Mental State Examination (MMSE) twice during the period. Retrospective changes in the hippocampal width and the MMSE scores were evaluated. There were significant CDR group effects for the changes in the mean bilateral hippocampal widths and the MMSE scores. Normal subjects did not show cognitive decline, although there was a slight tendency for hippocampal atrophy. A significant and meaningful Spearman's correlation was noted between left hippocampal atrophy and the MMSE scores over the 5-year period for the CDR-0.5 group. These CDR-0.5 subjects met the MCI (mild cognitive impairment) criteria as proposed by the consensus paper. Findings suggested that normal elderly subjects maintain a high level of cognitive functions for at least 5 years, although hippocampal atrophy might occur. Atrophic change of the left hippocampus might be a good marker of the very early stage of AD. (orig.)

    1996-03-01

    As life expectancy increases and spinal imaging techniques improve, surgery is being increasingly viewed as a therapeutic alternative for symptomatic lumbar spinal stenosis in patients older than 80 years. Thirty-four patients (21 men and 13 women) who had surgery for lumbar spinal stenosis in our department between 1979 and 1994 were studied retrospectively. The most common initial symptoms were walking-related disorders (n = 29) and sciatica or femoral neuralgia (n = 34). All 34 patients underwent laminectomy at one or more levels. Ten patients also had a herniated disk. There were no deaths and only two patients had serious complications (persistent foot drop in one and left-sided hemiplegia in the other). Results were evaluated immediately after surgery and after three and 12 months. The overall result on pain and walking-related disorders was good in 53% of cases, acceptable in 32%, and poor in 15%. Our data suggest that surgery is a reasonable alternative in symptomatic elderly patients who are in good general health. Satisfactory results can be obtained although disabling complications can occur. PMID:8731237

    2015-01-01

    Objective. This study aimed to estimate the mean annual cost of treating type 2 diabetes mellitus patients (T2DM) including complications and comorbidities in Greece. Design. A noninterventional retrospective study was based on patient level data analysis (bottom-up approach) from medical records, with at least 10-year-follow-up data. Results. The total annual cost per patient for managing diabetes in Greece was estimated at € 7,111 and was, statistically significantly, higher for patients with inadequate glycemic control (Hba1c > 7%) versus patients with adequate control (Hba1c = 7%) (€ 7,783 versus € 6,366, resp.; P = 0.017). This was mainly attributed to difference in CV hospitalizations between groups 14/111 versus 4/100, respectively, OR = 3.46 (95% CI: 1.10-10.9) for inadequately controlled patients. The largest component of cost was management of comorbidities, accounting for 48% of costs, and pharmaceutical treatment at 35.9% while only 14.9% was attributed to diabetes treatment per se. Obese men and patients with poor education are the groups with higher treatment costs. Conclusions. This is the first study to capture all cost components and the real burden of diabetes in Greece. Comorbidities were found to account for almost half of total cost, significantly higher in nonoptimally controlled diabetes patients. PMID:26089887

  12. Exploring the Academic and Social Experiences of Latino Engineering Community College Transfer Students at a 4-Year Institution: A Qualitative Research Study

    Hagler, LaTesha R.

    As the number of historically underrepresented populations transfer from community college to university to pursue baccalaureate degrees in science, technology, engineering, and mathematics (STEM), little research exists about the challenges and successes Latino students experience as they transition from 2-year colleges to 4-year universities. Thus, institutions of higher education have limited insight to inform their policies, practices, and strategic planning in developing effective sources of support, services, and programs for underrepresented students in STEM disciplines. This qualitative research study explored the academic and social experiences of 14 Latino engineering community college transfer students at one university. Specifically, this study examined the lived experiences of minority community college transfer students' transition into and persistence at a 4-year institution. The conceptual framework applied to this study was Schlossberg's Transition Theory, which analyzed the participant's social and academic experiences that led to their successful transition from community college to university. Three themes emerged from the narrative data analysis: (a) Academic Experiences, (b) Social Experiences, and (c) Sources of Support. The findings indicate that engineering community college transfer students experience many challenges in their transition into and persistence at 4-year institutions. Some of the challenges include lack of academic preparedness, environmental challenges, lack of time management skills and faculty serving the role as institutional agents.

    2010-07-01

    Full Text Available The University of Tasmania’s (UTAS UniStart program is a pre- and early-semester academic transition support program available to all HECs-eligible incoming students. The aim of the program is to nurture critical thinking and independent study skills in commencing students. UniStart has been offered to commencing UTAS students for over 10 years, with a significant increase both in enrolments and in the flexibility of delivery over recent years. Evaluation of the program indicates that students feel more confident and prepared for their academic studies after undertaking the program and that the majority of students affirm, later in the year, that they have utilised and applied the skills developed in UniStart during their core studies. The program represents an important component of the university’s approach to supporting the first-year experience and student transition.

  1. Treatment Outcome of Tuberculosis Patients under Directly Observed Treatment Short Course and Factors Affecting Outcome in Southern Ethiopia: A Five-Year Retrospective Study.

    Gebremedhin Gebrezgabiher

    Full Text Available Tuberculosis (TB is one of the major public health and socio-economic issues in the 21st century globally. Assessment of TB treatment outcomes, and monitoring and evaluation of its risk factors in Directly Observed Treatment Short Course (DOTS are among the major indicators of the performance of a national TB control program. Hence, this institution-based retrospective study was conducted to determine the treatment outcome of TB patients and investigate factors associated with unsuccessful outcome at Dilla University Referral Hospital, southern Ethiopia. Five years (2008 to 2013 TB record of TB clinic of the hospital was reviewed. A total 1537 registered TB patients with complete information were included. Of these, 942 (61.3% were male, 1015 (66% were from rural areas, 544 (35.4% were smear positive pulmonary TB (PTB+, 816 (53.1% were smear negative pulmonary TB (PTB- and 177(11.5% were extra pulmonary TB (EPTB patients. Records of the 1537 TB patients showed that 181 (11.8% were cured, 1129(73.5% completed treatment, 171 (11.1% defaulted, 52 (3.4% died and 4 (0.3% had treatment failure. The overall mean treatment success rate of the TB patients was 85.2%. The treatment success rate of the TB patients increased from 80.5% in September 2008-August 2009 to 84.8% in September 2012-May 2013. Tuberculosis type, age, residence and year of treatment were significantly associated with unsuccessful treatment outcome. The risk of unsuccessful outcome was significantly higher among TB patients from rural areas (AOR = 1.63, 95% CI: 1.21-2.20 compared to their urban counterparts. Unsuccessful treatment outcome was also observed in PTB- patients (AOR = 1.77, 95% CI: 1.26-2.50 and EPTB (AOR = 2.07, 95% CI: 1.28-3.37 compared to the PTB+ patients. In conclusion, it appears that DOTS have improved treatment success in the hospital during five years.

    Malaria is a major public health problem in Ethiopia. Over the past years, the disease has been consistently reported as the first leading cause of outpatient visits, hospitalization and death in health facilities across the country. Thus, a retrospective study was conducted to determine the prevalence of malaria from peripheral blood smear examination from the Serbo Health Center of Ethiopia. The case notes of all malaria cases treated between July 2007 and June 2008 were carefully reviewed and analyzed. Of the total 6863 smears, 3009 were found to be positive and contribute 43.8% of diagnostic yield. Plasmodium falciparum constituted the most predominant [64.6% (1946/3009 cases)], while Plasmodium vivax confirmed with 34.9% (1052/3009) cases. Among patients who underwent diagnostic testing and treatment for malaria, males [63.8% (1918/3009 cases)] were more prone to have a positive malaria smear than females [36.2% (1091/3009 cases)]. Chi-square statistical analysis shown that there was a statistically significant association found between male cases and number of positive blood smear (chi(2)=28.1; df=7; p-value=0.001). The present study results clearly suggest that the catchment area of Serbo Health Center is prone for epidemic malaria and the situation is quite deteriorating. At the moment, although we are not equipped with magic bullet for malaria effective low-cost strategies are available for its treatment, prevention, and control. Therefore, creating awareness by active health education campaigns and applying integrated malaria control strategy could bring the constructive outcome in the near future. PMID:20701879

  3. Hypercholesterolemia is associated with the apolipoprotein C-III (APOC3 genotype in children receiving HAART: an eight-year retrospective study.

    Carlos A Rocco

    Full Text Available Polymorphisms in apolipoprotein genes have shown to be predictors of plasma lipid levels in adult cohorts receiving highly active antiretroviral therapy (HAART. Our objective was to confirm the association between the APOC3 genotype and plasma lipid levels in an HIV-1-infected pediatric cohort exposed to HAART. A total of 130 HIV-1-infected children/adolescents that attended a reference center in Argentina were selected for an 8-year longitudinal study with retrospective data collection. Longitudinal measurements of plasma triglycerides, total cholesterol, HDL-C and LDL-C were analyzed under linear or generalized linear mixed models. The contribution of the APOC3 genotype at sites -482, -455 and 3238 to plasma lipid levels prediction was tested after adjusting for potential confounders. Four major APOC3 haplotypes were observed for sites -482/-455/3238, with estimated frequencies of 0.60 (C/T/C, 0.14 (T/C/C, 0.11 (C/C/C, and 0.11 (T/C/G. The APOC3 genotype showed a significant effect only for the prediction of total cholesterol levels (p<0.0001. However, the magnitude of the differences observed was dependent on the drug combination (p = 0.0007 and the drug exposure duration at the time of the plasma lipid measurement (p = 0.0002. A lower risk of hypercholesterolemia was predicted for double and triple heterozygous individuals, mainly at the first few months after the initiation of Ritonavir-boosted protease inhibitor-based regimens. We report for the first time a significant contribution of the genotype to total cholesterol levels in a pediatric cohort under HAART. The genetic determination of APOC3 might have an impact on a large portion of HIV-1-infected children at the time of choosing the treatment regimens or on the counter-measures against the adverse effects of drugs.

    Clear cell papillary renal cell carcinoma (CCPRCC) is a recently recognized subtype of renal cell carcinoma entity after 2004 World Health Organization classification of renal tumors. CCPRCC has unique histomorphological and immunohistochemical characteristics. The distinction of CCPRCC from renal cell carcinoma (RCC) with clear cell morphology is crucial because the former is considered to have a favorable clinical outcome. CCPRCC may be interpreted in the past as other renal cell carcinomas, particularly low-grade clear cell RCC. In this study, the frequency of CCPRCC in previously diagnosed low-grade RCC and its clinicopathologic features were examined. A total of 126 cases of stage T1a with low nuclear grade RCC were identified from 625 consecutive RCCs removed by radical/partial nephrectomy over 12-year period (2000-2011). Archival tissue sections were retrospectively reviewed along with patient medical charts. Eight cases (1.3% of all RCC, 6.3% of pT1a low grade RCC) with characteristic histologic features of CCPRCC were confirmed by immunohistochemical studies. Seven cases were previously diagnosed as clear cell RCC and one as multilocular cystic RCC. Radiographically, CCPRCC favored a mid-pole location in the kidneys. At a median follow-up period of 52 months (range 20-114.5 months), there were no cases of local or distant recurrence. In conclusion, CCPRCC is not uncommon among small low-grade RCC tumors. CCPRCC can be correctly recognized by its unique histomorphological features and confirmed by immunohistochemistry studies, which is important due to the excellent clinical outcome following resection.

    2015-01-01

    To investigate the spread of multiple-resistant strain in a burn ward to inform clinical administration of antibiotic drugs, burn wound treatment and decision-making for infection control. A 3-year retrospective analysis was conducted. Specimens from wounds, blood, catheter, sputum, urine and stool collected from inpatients of the Second Affiliated Hospital of Zhejiang University of Medicine between January 1, 2011 and December 31, 2013 were cultured and strains were identified by automatic bacteria analysis. Sensitivity to 30 commonly used antibiotics was assessed by K-B disk diffusion. A total of 2212 strains of pathogenic bacteria or fungi were isolated (33.9% Gram-positive and 52.7% Gram-negative bacteria and 13.4% fungi), including 1466 from wound extracts, 128 from blood culture, 335 from urine culture, 5 from stool culture, 153 from sputum culture and 125 from catheters. The most frequently detected pathogens in wound secretions were Staphylococcus aureus, Pseudomonas aeruginosa and Acinetobacter baumannii. The Gram-positive bacteria Staphylococcus epidermidis, Enterococcus faecalis and Enterococcus faecium, and the Gram-negative bacteria Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Stenotrophomonas maltophilia, Proteus mirabilis were also frequently detected. The most frequently detected strains of fungi were Candida albicans; tropicalis, glabrata and parapsilosis, and all were highly sensitive to itraconazole, fluconazole and voriconazole but resistant to ketoconazole. Attention should be paid to MRSA, multi-resistant A. baumanni, ESBL-producing enterobacteriaceae and Carbapenem-resistant P. aeruginosa. Understanding the distribution of bacterial infections in Chinese hospitals will be crucial to reduce hospital-acquired infection and drug resistance. PMID:26770555

    Background Despite implementation of different strategies, the burden and mortality of human immunodeficiency virus (HIV)-associated tuberculosis (TB) remains a challenge in Ethiopia. The aim of this study was to assess the impact of HIV status on treatment outcome of tuberculosis patients registered at Arsi Negele Health Center, Southern Ethiopia. Methods A six-year retrospective data (from September 2008 to August 2014) of tuberculosis patients (n = 1649) registered at the directly observed therapy short-course (DOTS) clinic of Arsi Negele Health Center was reviewed. Treatment outcome and tuberculosis type were categorized according to the national tuberculosis control program guideline. Data were entered and analyzed using SPSS version 20. Multinomial logistic regression analysis was used to examine the effect of HIV status separately on default/failure and death in relation to those who were successfully treated. Odds ratios with 95% confidence intervals were used to check the presence and strength of association between TB treatment outcome and HIV status and other independent variables. Results Out of the 1649 TB patients, 94.7% (1562) have been tested for HIV of whom 156(10%) were HIV co-infected. The mean (standard deviation) age of the patients was 28.5(15.5) years. The majority were new TB cases (96.7%), male (53.7%), urban (54.7%), and had smear negative pulmonary TB (44.1%). Overall, the treatment success rate of TB patients with or without HIV was 87.3%. Using cure/completion as reference, patients without known HIV status had significantly higher odds of default /failure [aOR, 4.26; 95%CI, 1.684–10.775] and transfer-out [aOR, 2.92; 95%CI, 1.545–5.521] whereas those who tested positive for HIV had a significantly higher odds of death [aOR, 6.72; 95%CI, 3.704–12.202] and transfer-out [aOR, 2.02; 95%CI, 1.111–3.680]. Conclusion Overall, treatment outcome and HIV testing coverage for TB patients is promising to reach the WHO target in the study

We know little about the use of opioids in ameliorating dyspnea in this population. In this study we explored factors associated with opioid dispensation within the last year of life and differences in opioid dispensation for persons with lung cancer or COPD.Methods: In this retrospective cohort study we used administrative health data gained from 1,035 residents of Saskatchewan, Canada to examine patterns of community opioid dispensation in the last year of life. Factors associated with opioid use were determined using multiple logistic regression.Results: When compared with those with lung cancer, fewer patients with COPD were given opioids within the last week of life; the last month of life, and the last 3 months of life. After adjusting for relevant predictors, patients with lung cancer were more than twice as likely as those with COPD to fill prescriptions for the following: morphine (odds ratio [OR] 2.36, 95% confidence interval [CI]: 1.52–3.67; hydromorphone (OR 2.69, 95% CI: 1.53–4.72; transdermal fentanyl (OR 2.25, 95% CI: 1.28–3.98; or any of these opioids (OR 2.61, 95% CI: 1.80–3.80.Conclusion: These opioids are dispensed only for a small proportion of patients with COPD at the end of their lives. Future researchers could explore the efficacy and safety of opioid use for patients with advanced COPD, and whether their limited use is justified.Keywords: COPD, lung cancer, dyspnea, opioid dispensation, palliative care

  8. A nation-wide multicenter 10-year (1999-2008 retrospective clinical study of endocrine therapy for Chinese females with breast cancer.

    Can Zhou

    Full Text Available Endocrine therapy (ET is one of the main systemic treatments for patients with breast cancer. To our knowledge, few studies have addressed the performance of ET or relevant influencing factors in cancer treatment in China. By retrospectively analyzing the clinicopathological data on breast cancer collected from representative hospitals of 7 traditional areas in China in one random month from each year between year 1999 and 2008, we found that: 1 The rate of the use of hormone receptor (HR testing was 83.8% (3529/4211, with the estrogen receptor-positive (ER+ rate and/or the progesterone receptor-positive (PR+ rate being 67.9% (2395/3529, and the ER-PR rate being 32.1% (1134/3529. 2 Of the 1599 patients who had received ET, 999 patients (58.3% were premenopausal while 600 (41.7% were postmenopausal; 1598 patients received adjuvant hormonal therapy (AHT, whereas only 1 patient received palliative therapy. The medications mainly administered to patients were anti-estrogen agents (80.3% [1283/1598], followed by AIs (15.5% [248/1598]. Of the 1598 patients receiving AHT, 1416 patients (88.6% were positive for ER and/or PR, while 75 (4.7% were negative for both and 108 patients (6.7% had unknown HR status. The ratio of the use of endocrine therapy for breast cancer patients with ER+ and/or PR+ status was 60.0% (1416/2395. 3 Results from the logistic regression analysis revealed that geography, occupations, and history of chemotherapy and surgery were dependent factors affecting the application of ET in breast cancer treatment in China (P<0.001. In conclusion, the use of ET on Chinese women with breast cancer is increasingly and gradually accounted into the standardized process. Economic status, occupations, and history of chemotherapy and surgery were key factors affecting the application of ET. People residing in developed areas, engaging in mental labour, having history of chemotherapy and surgery are susceptible to accept ET.

    Deliberate drug poisoning leads to 1% of emergency department (ED) admissions. Even if most patients do not exhibit any significant complication, 5% need to be referred to an intensive care unit (ICU). Emergency physicians should distinguish between low- and high-acuity poisoned patients at an early stage to avoid excess morbidity. Our aim was to identify ICU transfer factors in deliberately self-poisoned patients without life-threatening symptoms on admission. We performed a 3-year retrospective observational study in a university hospital. Patients over 18 years of age with a diagnosis of deliberate drug poisoning were included. Clinical and toxicological data were analysed with univariate tests between groups (ED stay versus ICU transfer). Factors associated with ICU admission were then included in a logistic regression analysis. Two thousand five hundred and sixty-five patients were included. 63.2% were women, and median age was 40 (28-49). 142 patients (5.5%) were transferred to ICU. Cardiac drugs [adjusted OR (aOR) = 19.81; 95% confidence interval (95% CI): 7.93-49.50], neuroleptics (aOR = 2.78; 95% CI: 1.55-4.97) and meprobamate (aOR = 2.71; 95% CI: 1.27-5.81) ingestions were significantly linked to ICU admission. A presumed toxic dose ingestion (aOR = 2.27; 95% CI: 1.28-4.02), number of ingested tablets (aOR = 1.01; 95% CI: 1.01-1.02 for each tablet) and delay between ingestion and ED arrival <2 hr (aOR = 2.85; 95%CI: 1.62-5.03) were also factors for ICU referral. The Glasgow Coma Scale was the only clinical feature associated with ICU admission (aOR = 1.57; 95% CI: 1.44-1.70 for each point loss). These results suggest that emergency physicians should pay particular attention to toxicological data on ED admission to distinguish between low- and high-acuity self-poisoned patients.

  12. Factors Associated with Advanced Inferior Vena Cava Filter Removals: A Single-Center Retrospective Study of 203 Patients Over 7 Years

    PurposeTo identify factors associated with advanced inferior vena cava filter (IVCF) retrieval to raise awareness on technical considerations, retrieval efficiency, and patient safety.Materials and MethodsA single-center retrospective review was performed of 203 consecutive retrievable IVC filters placed between 2007 and 2014. Attempted retrievals were classified as advanced if the routine “snare and sheath” technique was initially unsuccessful after multiple attempts, or an alternate endovascular maneuver or access site was utilized. Patient and filter characteristics were recorded.Results203 attempted retrievals were reviewed (48.7 % male, 51.2 % female, mean age 52.7 years, mean dwell time 109 days). Advanced retrievals were observed in 20 patients (9.8 %) (15 females, 5 males). Fluoroscopy time (p ≤ 0.01, 34.3 ± 21.1 and 5.3 ± 4.5 min for advanced retrievals and routine retrievals respectively, same below), gender (p = 0.031), and retrieval tilt angle (p ≤ 0.01, 5.7 ± 5.10° vs. 11.9 ± 11.03°) were associated with advanced retrievals. Females were 3.16 times more likely to have an advanced retrieval performed than males with a significantly higher tilt angle in those with advanced retrieval. History of cancer (p = 0.502), dwell time (p = 0.916), retrieval caval diameter (p = 0.053), placement caval diameter (p = 0.365), filter type (p = 0.710), strut perforation (p = 0.506), placement tilt angle (p = 0.311), and age (p = 0.558) were not found significantly associated with advanced retrievals.ConclusionsWomen are at increased risk for advanced filter retrieval secondary to a significant change in filter tilt over time compared to men, independent of filter type or competing demographic or filter risks, likely placing them at increased risk for higher procedural fluoroscopy times

  13. Predictors of Standard Follow-Up Completion after Sexual Exposure to HIV: Five-Year Retrospective Analysis in a French HIV-Infection Care Center.

    Pierre Gantner

    Full Text Available The care of exposed individuals to HIV remains a challenge regarding follow-up completion and HIV-testing of the partner. Identifying patients with risk of not fulfilling HIV-testing follow-up completion (FC, among patients demanding non-occupational post-exposure prophylaxis (nPEP, may improve clinical practice.A retrospective chart review was conducted in a single French HIV-infection care center. FC predictors were assessed in a multivariate logistic regression model (Likelihood ratios test.Between 2009 and 2013, 646 sexual exposures to HIV were evaluated for nPEP, of which 507 effectively received nPEP (78%. FC rate was 30% (194/646. In the multivariate analysis, FC rates rose with age of exposed individuals (OR, 1.04 [0.25-4.28]; p<0.001 and decreased with the year of sexual exposure (OR, 0.74 [0.65-0.85]; p<0.001. FC was associated with sexual encounter with a sex worker (OR, 4.07 [0.98-16.82]; p<0.001 and nPEP use (OR, 2.69 [2.37-3.06]; p<0.001. nPEP early discontinuation was associated with decreased FC rates (OR, 0.18 [0.08-0.39]; p<0.001. No documented nPEP failure was identified. However, five Men who have Sex with Men (MSM nPEP recipients for unprotected anal receptive intercourse subsequently seroconverted to HIV more than 6 months after nPEP. Seroconversion to HIV was associated with the lack of FC (p = 0.04 and multiple presentations for nPEP over the study period (p = 0.002.We identified significant predictors of not fulfilling sequential HIV-testing. They appear to be linked with a self-perceived HIV risk, especially in young adults recently exposed. Enhanced counseling in targeted individuals with high risk behaviors and using smartphone and internet-based strategies may be interesting retention in care options.

  15. Limnology of Blue Mesa, Morrow Point, and Crystal Reservoirs, Curecanti National Recreation area, during 1999, and a 25-year retrospective of nutrient conditions in Blue Mesa Reservoir, Colorado

    Bauch, Nancy J.; Malick, Matt

    2003-01-01

    The U.S. Geological Survey and the National Park Service conducted a water-quality investigation in Curecanti National Recreation Area in Colorado from April through December 1999. Current (as of 1999) limnological characteristics, including nutrients, phytoplankton, chlorophyll-a, trophic status, and the water quality of stream inflows and reservoir outflows, of Blue Mesa, Morrow Point, and Crystal Reservoirs were assessed, and a 25-year retrospective of nutrient conditions in Blue Mesa Reservoir was conducted. The three reservoirs are in a series on the Gunnison River, with an upstream to downstream order of Blue Mesa, Morrow Point, and Crystal Reservoirs. Physical properties and water-quality samples were collected four times during 1999 from reservoir, inflow, and outflow sites in and around the recreation area. Samples were analyzed for nutrients, phytoplankton and chlorophyll-a (reservoir sites only), and suspended sediment (stream inflows only). Nutrient concentrations in the reservoirs were low; median total nitrogen and phosphorus concentrations were less than 0.4 and 0.06 milligram per liter, respectively. During water-column stratification, samples collected at depth had higher nutrient concentrations than photic-zone samples. Phytoplankton community and density were affected by water temperature, nutrients, and water residence time. Diatoms were the dominant phytoplankton throughout the year in Morrow Point and Crystal Reservoirs and during spring and early winter in Blue Mesa Reservoir. Blue-green algae were dominant in Blue Mesa Reservoir during summer and fall. Phytoplankton density was highest in Blue Mesa Reservoir and lowest in Crystal Reservoir. Longer residence times and warmer temperatures in Blue Mesa Reservoir were favorable for phytoplankton growth and development. Shorter residence times and cooler temperatures in the downstream reservoirs probably limited phytoplankton growth and development. Median chlorophyll-a concentrations were higher

The practice in our institution is that all pregnant women attending the Antenatal clinic or Labour Room are counseled for HIV testing, and tested as per NACO guidelines. Babies born to HIV s e ropositive women are followed up to 18 months for confirmatory testing. RESULTS : The number of antenatal women counseled who opted for HIV testing were 99.4% and women who tested seropositive was 1.6 %, 1.3%, 0.9%, 0.84%, 0.6% for the years 2009 - 10, 10 - 11, 11 - 12, 12 - 13, 13 - 14 respectively showing a declining trend in the prevalence of HIV in antenatal women. 94.6% of women attended the post - test counseling . Spouses of ser o positive antenatal women who opted for testing was 52.5% and seropositivity in the spouses tested was 65.87% during the study period. Of the 767 seropositive women who delivered, 542(70.66% had vaginal delivery 225(29.33% had LSCS for obstetric indication. Of the 767 seropositive women who delivered 719(93.7% had live births, 28(3.65% had intrauterine fetal demise and 20(2.6% newborns died in the perinatal period. The number of seropositive women opting for exclusive replacement feeding was 54.4% during the study period April 2009 to March 2014. Confirmatory test for infants was done at 18 months and of the 136 infants tested, 14 were

    Full Text Available Abstract Background The professional development of under-represented faculty may be enhanced by mentorship, but we understand very little about the mechanisms by which mentoring brings about change. Our study posed the research question, what are the mechanisms by which mentoring may support professional development in under-represented groups? The study aims to: (i to pilot a mentoring scheme for female academics; (ii to compare various health-related and attitudinal measures in mentees at baseline, 6 months, and 1 year into the mentoring relationship and, (iii to compare pre-mentoring expectations to outcomes at 6 months and 1 year follow-up for mentees and mentors. Methods Female academic mentees were matched 1:1 or 2:1 with more senior academic mentors. Online surveys were conducted to compare health-related and attitudinal measures and expectations of mentoring at baseline with outcomes at 6 months and 1 year using paired t-tests and McNemar's test for matched cohort data. Results N = 46 mentoring pairs, 44 (96% mentees completed the pre-mentoring survey, 37 (80% at 6 months and 30 (65% at 1 year.

  10. Changes in teachers' involvement versus rejection and links with academic motivation during the first year of secondary education: a multilevel growth curve analysis.

    Maulana, Ridwan; Opdenakker, Marie-Christine; Stroet, Kim; Bosker, Roel

    2013-09-01

    Research consistently shows that the learning environment plays an important role for early adolescents' learning and outcomes and suggests that good teacher-student relationships can serve as a protective factor for maintaining young adolescents' interest and active engagement in learning. However, less is known about the dynamic nature of teacher-student relationships and how they link with academic motivation development. Furthermore, little is known about the nature and the effects of teacher-student relationships in a cross-national context. The present study investigated changes in two components of teacher-student relationships (teachers' involvement vs. rejection) and examined links with students' academic motivation during the first grade of secondary school. Ten Dutch and ten Indonesian teachers (65 % female) from 24 classes were videoed 12 times across the school year, and four videos for each class were selected randomly and coded on teachers' involvement versus rejection. A total of 713 students (52 % girls) completed four-wave measures of their academic motivation after each video observation. Multilevel growth curve modeling revealed that the teacher's involvement changed in a curvilinear way and decreased across the first year of secondary education, while changes in the teacher's rejection did not follow a linear time function. Academic motivation changed in an undesirable way: controlled motivation increased, while autonomous motivation decreased over time. Teachers' involvement had a unique contribution in preventing high levels of controlled motivation in both countries. Findings suggest that teacher-student relationships (teachers' involvement) play an essential role in early adolescents' motivation regardless of the nations and should be a priority for schools.

  12. Learning in the context of community: The academic experiences of first-year arts and science students in a learning community program

    Schmidt, Nancy

    2000-10-01

    This study explored the academic experiences of two groups of first-year students in university, one in the arts and one in the science, who participated in a residential-based learning community program. Using qualitative and critical analysis of in-depth student interviews conducted over a fall and winter semester, I constructed their world as implied from their stories and narratives. From this vantage point, I investigated how students as novice learners negotiated their role as learners; the belief systems they brought with them to minimize academic risk; their coping strategies in a 12 week semestered system; and the tacit theories they acquired within their day-to-day educational experiences. A number of themes emerged from the research: students intentionally minimizing faculty contact until they developed 'worthiness'; learning as 'teacher pleasing'; disciplinary learning differences between the arts and sciences students; and a grade orientation that influenced what and how students learned. Within the broader political, ideological, and cultural framework of the university, I identified student patterns of accommodation, resistance, silence and submission in negotiating their roles as learners. By critiquing the academic side of university life as students experienced it and lived it as a community of learners, I exposed the tensions, contradictions, and paradoxes that emerged. I revealed the points of disjuncture that came from competing discourses within the university for these students: the discourse of community, the discourse of collective harmony, and the discourse of the market place.

    2008-03-01

    Full Text Available Abstract Background The aim of this study was to assess the magnitude of the university population at high-risk of developing an eating disorder and the prevalence of unhealthy eating attitudes and behaviours amongst groups at risk; gender, school or academic year differences were also explored. Methods A cross-sectional study based on self-report was used to screen university students at high-risk for an eating disorder. The sample size was of 2551 university students enrolled in 13 schools between the ages of 18 and 26 years. The instruments included: a social-demographic questionnaire, the Eating Disorders Inventory (EDI, the Body Shape Questionnaire (BSQ, the Symptom Check List 90-R (SCL-90-R, and the Self-Esteem Scale (RSE. The sample design is a non-proportional stratified sample by academic year and school. The prevalence rate was estimated controlling academic year and school. Logistic regression analysis was used to investigate adjusted associations between gender, school and academic year. Results Female students presented unhealthy weight-control behaviours as dieting, laxatives use or self-induced vomiting to lose weight than males. A total of 6% of the females had a BMI of 17.5 or less or 2.5% had amenorrhea for 3 or more months. In contrast, a higher proportion of males (11.6% reported binge eating behaviour. The prevalence rate of students at high-risk for an eating disorder was 14.9% (11.6–18 for males and 20.8% (18.7–22.8 for females, according to an overall cut-off point on the EDI questionnaire. Prevalence rates presented statistically significant differences by gender (p Conclusion The prevalence of eating disorder risk in university students is high and is associated with unhealthy weight-control practices, similar results have been found in previous studies using cut-off points in questionnaires. These results may be taken into account to encourage early detection and a greater awareness for seeking treatment in order

  15. Self-report measures of executive functioning are a determinant of academic performance in first-year students at a university of applied sciences.

    2015-01-01

    Recent studies in late adolescents (age 17+) show that brain development may proceed till around the 25th year of age. This implies that study performance in higher education could be dependent upon the stage of brain maturation and neuropsychological development. Individual differences in development of neuropsychological skills may thus have a substantial influence on the outcome of the educational process. This hypothesis was evaluated in a large survey of 1760 first-year students at a University of Applied Sciences, of which 1332 are included in the current analyses. This was because of their fit within the age range we pre-set (17-20 years' old at start of studies). Student characteristics and three behavioral ratings of executive functioning (EF) were evaluated with regard to their influence on academic performance. Self-report measures were used: self-reported attention, planning, and self-control and self-monitoring. Results showed that students with better self-reported EF at the start of the first year of their studies obtained more study credits at the end of that year than students with a lower EF self-rating. The correlation between self-control and self-monitoring on the one hand, and study progress on the other, appeared to differ for male and female students and to be influenced by the level of prior education. The results of this large-scale study could have practical relevance. The profound individual differences between students may at least partly be a consequence of their stage of development as an adolescent. Students who show lower levels of attention control, planning, and self-control/self-monitoring can be expected to have a problem in study planning and study progress monitoring and hence study progress. The findings imply that interventions directed at the training of these (executive) functions should be developed and used in higher education in order to improve academic achievement, learning attitude, and motivation.

    Full Text Available Abstract Background To determine the epidemiological characteristics and visual outcome of ocular trauma in southern Italy. Methods All cases of ocular trauma admitted to Department of Ophthalmology of Palermo University, Italy, from January 2001–December 2005 were retrospectively reviewed for open- or closed-globe injury (OGI or CGI. Data extracted included age, sex, residence, initial and final visual acuity (VA, cause and treatment of injury, hospitalization. The injuries were classified by Ocular Trauma Classification System (OTCS and Birmingham Eye Trauma Terminology (BETT. We also referred to the Ocular Trauma Score (OTS in evaluating the final visual outcome. Results Of the 298 eyes, there were 146 OGI and 152 CGI. Fifty eyes (16.8% had an intraocular foreign body (IOFB. The annual incidence of eye injuries was 4.9 per 100,000. Most injuries occurred in men (84.6%, p The incidence of OGI and CGI differed in work-related injuries (p Conclusion This analysis provides insight into the epidemiology of patients hospitalized for ocular trauma. The findings indicate that ocular trauma is a significant cause of visual loss in this population.

  19. Positive malignant margins in clinically diagnosed and excised benign breast lumps: a five year retrospective study at the Korle-Bu Teaching Hospital, Ghana

    This study was aimed at utilizing retrospective descriptive data to evaluate the percentage of clinically benign breast lumps that turned out to be histologically malignant and the prevalence of positive tumour margins among the malignant cases. A total of 2,917 registered cases of excised breast lump at the Department of Pathology spanning January 2005 to December 2009 were reviewed to evaluate the presence of malignancy and positive margins. Three hundred and twenty-two (11.0%) of the excised breast lumps were found to contain malignant tumours, out of which 142(44.1%) had positive tumour margins. Size of primary tumour (p=0.001) and histologic subtype (p=0.002) showed significant positive and negative associations in relation to positive tumour margins respectively. No significant association was observed between the positive tumour margins and histologic grade (p=0.363). The study showed that clinically benign breast lumps could be malignant and not completely excised, therefore increasing the risk of local recurrence. Thus, it is recommended that all women with breast lumps have the triad (diagnostic workup) of clinical and radiological assessment, followed with histological studies. (au)

    Yin Zhang; Tao Cheng; Xian-Long Zhang

    2015-01-01

    Background:Total hip arthroplasty (THA) is one of the most effective treatments for phase Ⅲ and Ⅳ hip arthrosis.Lower limb length balancing is one of the determining factors of a successful surgery,particularly in patients with developmental dysplasia of the hip (DDH).The purpose of this study was to evaluate the postoperative change in intra-pelvic obliquity (intra-PO) angle in the coronal plane and its effects on leg length discrepancy (LLD) within 2 years.Methods:A total of 78 patients (70 females,8 males) were enrolled in this study.All patients were suffering from DDH with varying degrees of LLD.Pelvic plain radiographs were collected before and after the operation.The intra-PO angles were measured 0,0.5,1 and 2 years after THA.At the same time,postoperative LLD was measured with blocking test.Results:PO changed significantly in the first year after THA surgery (0 year vs.0.5 year,P < 0.01;0.5 year vs.1 year,P < 0.01),and the changing value of intra-PO angle (△PO) slowed down substantially during the first 2 years after THA (0.5 year vs.0.5-1 year,P < 0.01;0.5-1 year vs.1-2 years,P < 0.01).With the change in intra-PO angle,LLD also got narrow within the 1st year (0 year vs.0.5 year,P < 0.01;0.5 year vs.1 year,P < 0.01).Elderly patients had a smaller intra-PO angle reduction (Group A vs.Group B,P =0.01;Group B vs.Group C,P< 0.01).Conclusions:Intra-PO angle and LLD gap narrowed with time after THA surgery.In particular,elderly patients had smaller change in intra-PO angle.

    Full Text Available Background and Design: In this retrospective study, patch test results of 304 patients with allergic contact dermatitis (ACD, who were tested with the European Standard Series, were evaluated. The aim of the study was to determine the frequency of positive reactions to different sensitizers in patients with ACD and to identify sex and age differences.Material and Method: We evaluated a total of 304 patients (195 (64.1% female and 109 (35.9% male who applied to our clinic between the period of January 2003 and December 2008 and who were tested with patch test with the consideration of ACD. Patch test results were assessed according to the International Contact Dermatitis Research Group at 48 and 72 hours after initial application.Results: Lesions of ACD were found to be most frequent on the hands (65.5%. A total of 95 (31.3% patients had one or more positive patch test reactions. The most common allergens were nickel sulfate (14.8% followed by cobalt chloride (9.2%, potassium dichromate (6.6%, balsam of Peru (3.6%, fragrance mix (3.3%, mercaptobenzothiazole (3% and colophonium (2.3%. Positive reactions to nickel sulfate were more common among women, especially those in younger group. Frequency of contact allergy to lanolin, mercapto mix, epoxy resin, paraben mix and quaternium-15 were relatively low, while no positive reaction was obtained to formaldehyde in any case. In 51.6% of patients with positive reaction, the responsible allergen was detected by testing with the European Standard Series.Conclusion: Although this study shows that sensitization rate to metals and fragrance are still high in our region, as well as in our country, and are more frequent in females than in males, future prospective multicenter studies with large number of patients would point out the adequacy of the European Standard Series in our country.

  5. The role of scintigraphy and ultrasound in the imaging of neonatal hypothyroidism: 5-year retrospective review of single-centre experience

    Congenital hypothyroidism (CH), as indicated by an elevation of capillary thyroid-stimulating hormone (TSH) at newborn screening, is a preventable cause of mental retardation with varying aetiology; it can be transient or permanent. Radionuclide assessment is currently the gold standard for imaging CH. This study aimed to (i) review the different scintigraphic patterns and correlate them with TSH levels/patient outcomes, (ii) assess the role of sonography in neonates with apparent agenesis as indicated by scintigraphy and (iii) develop a diagnostic investigative algorithm. The technetium thyroid scans of 83 consecutive patients (49 females, average age 32 days) with CH scanned between 2005 and 2009 were retrospectively reviewed. Two nuclear medicine physicians blinded to the clinical details interpreted the scans in consensus. Scintigram appearances were categorised into five groups. Patients scintigraphically diagnosed with thyroid agenesis were evaluated with ultrasound. TSH values and scintigraphic and sonographic findings were correlated with patients' final diagnosis. Based on scintigraphy, 14, 13 and 19 patients out of 83 were assessed as having normal thyroid sites with normal, increased and decreased uptake, respectively. Twenty-two of 83 patients had no uptake, and 15 of 83 patients had ectopic uptake. Higher median TSH levels were seen in no-uptake and ectopic uptake subgroups. Eighteen of 22 patients with no uptake were evaluated with ultrasound. Three of the 18 patients had a normal thyroid gland, and three of 18 patients had a hypoplastic thyroid. Scintigram findings in patients with congenital hypothyroidism fall into five major categories, which have therapeutic implications (lifelong thyroxine in agenesis versus trial of stopping thyroxine in other subgroups). Sonographic demonstration of thyroid tissue in patients scintigraphically diagnosed with thyroid agenesis has major management implications.

    Based on the emission levels measured in the city of Bochum (approx. 20,000 readings), 1200 hospitalized children with pseudocroup were examined for a possible relationship between croup incidence and sulphur dioxide levels. Evaluation according to geographic location showed no statistically significant correlation between croup incidence and SO/sub 2/ levels over a test period of 13 years. Only for 3 of 13 years did Spearman's rank correlation coefficient show a weakly significant positive correlation (P less than 0.05). In one test year, however, there was a statistically significant negative correlation (P less than 0.025). Evaluation of the 16-year study in terms of time-dependent relationships yielded no significant deviation of pseudocroup incidence from the expected mean value for the individual SO/sub 2/ concentration ranges. Over the period of this study, there was therefore no cause-effect relationship between sulphur dioxide levels and pseudocroup incidence.

  8. Three Years of a Nonsurgical Periodontal Treatment Protocol to Observe Clinical Outcomes in ≥ 6-mm Pockets: A Retrospective Case Series.

    Roncati, Marisa; Gariffo, Annalisa

    2016-01-01

    A total of 25 patients were treated with a nonsurgical periodontal treatment protocol (NSPTP) consisting of four appointments (three within 1 week and one approximately 30 days later). Nonsurgical periodontal instrumentation was implemented, with the adjunctive use of thermal diode lasers (wavelength of 808 or 980 nm). The patients were scheduled for recall visits every 3 months and reevaluated 1 year post-NSPTP. They were subsequently monitored at 4-month intervals for the remaining 2-year follow-up maintenance period. In total, 698 teeth (210 multirooted and 488 single-rooted) were included in the study. The mean bleeding on probing was 43% at baseline and decreased to 12% at 12 months and to 8% at 3 years. The initial ≥ 6-mm probing pocket depth (PPD) in single-rooted teeth decreased from 6.2 mm at baseline to a mean of 1.8 mm at 12 months and remained at 1.8 mm at 3 years, with a mean clinical attachment level (CAL) gain of 4.4 mm. In multirooted teeth, the PPD decreased from 6.7 mm to a mean of 3.9 mm at 12 months and 3.6 mm at 3 years, with a mean CAL gain of 2.9 mm. The mean overall recession was 0.3 mm at baseline, 0.1 mm at 1 year, and 0.3 mm at the 3-year follow-up. In the short-term followup period, uniform and consistent implementation of the NSPTP used here with adjunctive use of thermal diode lasers seemed to convey therapeutic benefits, stable periodontal soft tissue levels, and satisfactory esthetics in patients with moderate to severe chronic periodontitis. The present protocol is relevant as a treatment option for medically compromised patients, those who refuse or delay surgical treatment, or those who present with other limitations. PMID:26901297

    Objectives There are very little data on pre-excitation syndrome (PS) in the elderly. We investigated the influence of advancing age on clinical presentation, treatment and long-term outcome of PS. Setting Single-centre retrospective study of patient files. Participants In all, 961 patients (72 patients ≥60 years (mean 68.5±6), 889 patients <60 years (mean 30.5±14)) referred for overt pre-excitation and indication for electrophysiological study (EPS) were followed for 5.3±5 years. Usual care included 24 h Holter monitoring, echocardiography and EPS. Patients underwent accessory pathway (AP) ablation if necessary. Primary and secondary outcome measures Occurrence of atrial fibrillation (AF) or procedure-induced adverse event. Results Electrophysiological data and recourse to AP ablation (43% vs 48.5%, p=0.375) did not significantly differ between the groups. Older patients more often had symptomatic forms (81% vs 63%, p=0.003), history of spontaneous AF (8% vs 3%, p=0.01) or adverse presentation (poorly tolerated arrhythmias: 18% vs 7%, p=0.0009). In multivariable analysis, patients ≥60 years had a significantly higher risk of history of AF (OR=4.2, 2.1 to 8.3, p=0.001) and poorly tolerated arrhythmias (OR=3.8, 1.8 to 8.1, p=0.001). Age ≥60 years was associated with an increased major AP ablation complication risk (10% vs 1.9%, p=0.006). During follow-up, occurrence of AF (13.9% vs 3.6%, p<0.001) and incidence of poorly tolerated tachycardia (4.2% vs 0.6%, p=0.001) were more frequent in patients ≥60 years, although frequency of ablation failure or recurrence was similar (20% vs 15.5%, p=0.52). In multivariable analysis, patients ≥60 years had a significantly higher risk of AF (OR=2.9, 1.2 to 6.8, p≤0.01). Conclusions In this retrospective monocentre study, patients ≥60 years referred for PS work up appeared at higher risk of AF and adverse presentation, both prior and after the work up. These results suggest that, in elderly

  1. Is sexual abuse a part of war? A 4-year retrospective study on cases of sexual abuse at the Kenyatta National Hospital, Kenya

    Mary W. Kuria

    2013-07-01

    Full Text Available The harmful effects of sexual abuse are long lasting. Sexual abuse when associated with violence is likely to impact negatively on the life of the victim. Anecdotal reports indicate that there was an increase in the number of cases of sexual violence following the 2007 post election conflict and violence in Kenya. Although such increases in sexual abuse are common during war or conflict periods the above reports have not been confirmed through research evidence. The purpose of the current study is to establish the trend in numbers of reported cases of sexual abuse at Kenyatta National Hospital over a 4-year period (2006-2009. Data on sexually abused persons for the year 2006-2009 was retrieved from the hospitals record. A researcher designed questionnaire was used to collect relevant data from the completed Post Rape Care (PRC form. The PRC-Ministry of Health no. 363 (MOH363 form is mandatorily completed by the physician attending the sexually abused patient. There was an increase in the number of cases of sexual abuse reported in 2007 election year in Kenya, with a statistically significant increase in the sexually abused male cases. Sexual crime is more prevalent when there is war or conflict.

  2. Aichi Cancer Center 10-year experience with conservative breast treatment of early breast cancer: retrospective analysis regarding failure patterns and factors influencing local control

    Purpose: We analyzed the clinical results of conservative breast therapy in our institute to determine the risk factors influencing local and distant disease recurrence. Methods and Materials: From 1989 to 1997, 301 breasts of 295 women with early breast cancer were treated with conservative surgery and adjuvant radiotherapy. There were 212 incidences of Stage I breast cancer, and 89 of Stage II. Patients were routinely treated with local resection, axillar dissection, and 46-50 Gy irradiation given in 23-25 fractions. Some also received a radiation boost to the tumor bed. Results: The 5-/8-year overall survival, disease-free survival, and local control rates were 93.2/91.5%, 86.0/80.6%, and 95.1/92.5%, respectively. Using both univariate and multivariate analyses, tumor volume, estrogen receptor status, and age <40 years were significant prognostic factors for disease-free survival. Both age <40 years and surgical method had a strong effect on local control by uni- and multivariate analysis. Surgical margin status was a significant prognostic factor for local control at the univariate level (p<0.0001), though it had only borderline significance at the multivariate level (p 0.08). No patient experienced severe morbidity due to radiotherapy. Conclusion: The results obtained are comparable to previously reported data. Although the follow-up period was too short to draw definite conclusions about long-term outcomes, the outcome from conservative breast treatment was acceptable

    Background Blood transfusion is considered a potential risk factor for transmission of life-threatening viral infections, including HIV, HCV and HBV infections. This study was performed to find out the prevalence and trends of these infections among blood donors in Southern Iran. Methods The blood donor data recorded in twelve regional blood transfusion centers from 2004 to 2014 were analyzed in an anonymous way with respect to the results of serological screening for HBV, HCV, and HIV infections. Overall, 293454 donors were screened for viral infections. Results Most of the donors were male, married, aged between 20–40 years, educated, and regular donors. The overall seroprevalence rates of HBV, HCV and HIV were 0.15%, 0.1% and 0.004%, respectively. The highest seroprevalence was found for HBV, followed by HCV and HIV. These infections were more prevalent in male, low educated and first time donors. The highest HCV seroprevalence was observed among donors aged 20 to 40 years, while HBV seroprevalence increased with age. The seroprevalence rates of HBV and HCV from 2004 to 2014 showed significant decreasing trends from 0.460% to 0.060% (P < 0.001) and 0.329% to 0.045% (P < 0.001), respectively. Whereas HIV infection had a slight but not significant decline from 0.0173% in 2004 to 0.0028% in 2014 (P = 0.087). Conclusions The decreasing trends of transfusion-transmissible viral infections in blood donations indicate that the attempts of IBTO were successful in improving the safety of the blood supply, since the prevalence rates of viral infections have been reduced to very low levels in blood donations over the years. However, still more effective techniques such as polymerase chain reaction (PCR) are needed to guarantee blood safety. PMID:27309959

    Limited information is available on the incidence of Clostridium difficile infections (CDIs) in Italian hospitals. In this study, we assessed the changes in the incidence of CDI over a 5-year period in a teaching hospital in Liguria, the Italian region with the oldest population. Secondary endpoints were the development of severe CDI and 30-day mortality. The annual incidence of CDI/10000 patient-days significantly increased from 0·54 in 2010 to 3·04 in 2014 (χ 2 for trend, P < 0·001). The median age of patients with CDI was 81 years. As many as 81% and 89% of these patients had comorbid conditions and previous exposure to antibiotics, respectively. In the multivariate analysis of risk factors for severe CDI, previous therapy with histamine 2 blockers and low serum albumin were associated with severe CDI, while diabetes appeared to be protective. In the multivariate model of risk factors for 30-day mortality, high leukocyte count, low serum albumin, and increased serum creatinine were unfavourably associated with outcome. Strict adherence to infection control measures was of utmost importance to counteract the increasing incidence of CDI in our hospital, particularly because of the advanced age of the patients and their very high frequency of chronic conditions and use of antibiotics, which readily predispose them to the development of CDI.

    Background Academic achievement of school age children can be affected by several factors such as nutritional status, demographics, and socioeconomic factors. Though evidence about the magnitude of malnutrition is well established in Ethiopia, there is a paucity of evidence about the association of nutritional status with academic performance among the nation’s school age children. Hence, this study aimed to determine how nutritional status and cognitive function are associated with academic ...

  12. Selection criteria predictive of academic success in the first two years of the integrated diploma in nursing

    L. R. Uys

    1993-05-01

    Full Text Available Student wastage during basic nursing programmes has been estimated at between 20% and 47% per annum over the last 10 years (Kotze, 1987; SANA, 1983. The training of every student costs the state approximately R13 500 per annum according to an investigation done by the SA Nursing Association in 1987. The economic loss due to the student wastage is therefore significant. At the same time student numbers are declining at a time during which many more nurses are necessary to maintain the ratio of registered nurses to the population (Kotze, 1987. The student wastage therefore also has serious implications for the health services. Since training schools usually receive more applications than can be accommodated as students, the process of selection becomes a key factor in selecting students who will complete the programme and join the professional nursing cadre.

    Trockel, M T; Barnes, M D; Egget, D L

    2000-11-01

    The authors analyzed the effect of several health behaviors and health-related variables on grade point averages of a random sample of 200 students living in on-campus residence halls at a large private university. The set of variables included exercise, eating, and sleep habits; mood states; perceived stress; time management; social support; spiritual or religious habits; number of hours worked per week; gender; and age. Of all the variables considered, sleep habits, particularly wake-up times, accounted for the largest amount of variance in grade point averages. Later wake-up times were associated with lower average grades. Variables associated with the 1st-year students' higher grade point averages were strength training and study of spiritually oriented material. The number of paid or volunteer hours worked per week was associated with lower average grades. PMID:11125640

Diagnosis ditegakkan berdasarkan klinis, laboratories, imaging, bakteriologis dan histopathologis. Sampai saat ini belum ada therapi definitif yang baku. Masih ada kontroversi antara terapi konservative dengan pembedahan. Telah dikembangkan metode total treatment yang merupakan gabungan terapi konservatif dan tindakan operatif berdasarkan identifikasi masalah yang dihadapi masing ? masing penderita.Therapi pembedahan dapat berupa radikal atau middle path, Study of spectrum of dengue fever and dengue hemorrhagic fever on children at Sanglah General Hospital Denpasar was done in 2005.Data were collected from medical records. Subject of this study were patients of dengue fever (DF and dengue hemorrhagic fever (DHF who were admitted to the pediatric department of Sanglah hospital from 1 January 2002 until 31 December 2004. There were 837 patients diagnosed, 582 were eligible to inclusion; 303 (52.1% males and 279 (47.9% females. Most of them were diagnosed with DF 417 (71.6%, DHF 95 (16.3%, and DHF with shock 70 (12.0%. Five patients (0.8% died because of DHF with shock in three years and 4 of them were females. Patients mostly came on the fourth day 337 (57.9%. Vomiting 283 (48.6%, 66 (11.3% was the major symptom of patients with DF and DHF respectively, hepatomegaly 61(10.5% and abdominal pain 59 (10.1% were major symptoms of DHF with shock.

    The clinical data repository (CDR) is a frequently updated relational data warehouse that provides users with direct access to detailed, flexible, and rapid retrospective views of clinical, administrative, and financial patient data for the University of Virginia Health System. This article presents a case study of the CDR, detailing its five-year history and focusing on the unique role of data warehousing in an academic medical center. Specifically, the CDR must support multiple missions, including research and education, in addition to administration and management. Users include not only analysts and administrators but clinicians, researchers, and students. PMID:11452578

    Full Text Available Abstract Background Cervical cancer is one of the most common AIDS-related malignancies in Thailand. To prevent cervical cancer, The US Public Health Service and The Infectious Disease Society of America have recommended that all HIV-infected women should obtain 2 Pap smears 6 months apart after the initial HIV diagnosis and, if results of both are normal, should undergo annual cytological screening. However, there has been no evidence in supporting whether this guideline is appropriate in all settings - especially in areas where HIV-infected women are living in resource-constrained condition. Methods To determine the appropriate interval of Pap smear screenings for HIV-infected Thai women and risk factors for subsequent abnormal cervical cytology, we assessed the prevalence, cumulative incidence and associated factors of cervical cell abnormalities (atypical squamous cell of undetermined significance or higher grades, ASCUS+ among this group of patients. Results The prevalence of ASCUS+ was 15.4% at the first visit, and the cumulative incidence of ASCUS+ gradually increased to 37% in the first 3.5 years of follow-up appointments (first 7 times, and tended to plateau in the last 2 years. For multivariate correlation analysis, women with a CD4 count P = 0.043. There were no associations of subsequent ASCUS+ with age, pregnancy, contraceptive method, highly active anti-retroviral treatment, assumed duration of infection, or the CD4 count nadir level. Conclusion There are high prevalence and cumulative incidence of ASCUS+ in HIV-infected Thai women. With a high lost-to-follow-up rate, an appropriate interval of Pap smear screening cannot be concluded from the present study. Nevertheless, the HIV-infected Thai women may require more than two normal semi-annual Pap smears before shifting to routinely annual cytologic screening.

  18. Experience of radiotherapy in lethal midline granuloma with special emphasis on centrofacial T-cell lymphoma: a retrospective analysis covering a 34-year period

    Lethal midline granuloma (LMG) is characterized by progressive ulceration and destruction of the midfacial tissue. It occurs more frequently in Oriental than in Western populations. Because of the progress in clinical pathology and immunohistochemistry, most cases have been proven to be malignant lymphomas, especially of T-cell lineage. We describe 92 cases of lethal midline granuloma or centrofacial malignant lymphoma in the period 1959-1993. All received complete courses of radiotherapy. Twenty of them also received combination chemotherapy. Thirty-six cases had specimens available for immunohistochemical study; 25 (69%) of these had a T-cell phenotype, and 6 (17%) were of B-cell lineage. The dose to the nasal region was in the range of 3000-7500 cGy in 11-58 days, and to the neck 3000-6400 cGy in 11-48 days. The overall survival rate for the LMGs was 59.5% at 5 years and 56.2% at 10 years (Kaplan-Meier). Combined chemotherapy seemed not to improve the overall survival in this study (p = 0.63), but the patient number was too small to make a firm conclusion. Based on the results of this study, we recommend a dose of 4500-5000 cGy to the midfacial region, since a higher dosage did not improve the treatment results (p = 0.88). Irradiation has a definite role in good locoregional control of this disease. The recent clarification of the disease nature and the recognition of the background clinicopathological features should provide valuable information for future patient management and prospective studies

    Full Text Available Abstract Background Thoracic trauma is one of the leading causes of morbidity and mortality in developing countries. In this study, we present our 11-year experience in the management and clinical outcome of 888 chest trauma cases as a result of blunt and penetrating injuries in our university hospital in Damascus, Syria. Methods We reviewed files of 888 consequent cases of chest trauma between January 2000 and January 2011. The mean age of our patients was 31 ± 17 years mostly males with blunt injuries. Patients were evaluated and compared according to age, gender, etiology of trauma, thoracic and extra-thoracic injuries, complications, and mortality. Results The leading cause of the trauma was violence (41% followed by traffic accidents (33%. Pneumothorax (51%, Hemothorax (38%, rib fractures (34%, and lung contusion (15% were the most common types of injury. Associated injuries were documented in 36% of patients (extremities 19%, abdomen 13%, head 8%. A minority of the patients required thoracotomy (5.7%, and tube thoracostomy (56% was sufficient to manage the majority of cases. Mean hospital LOS was 4.5 ± 4.6 days. The overall mortoality rate was 1.8%, and morbidity (n = 78, 8.7%. Conclusions New traffic laws (including seat belt enforcement reduced incidence and severity of chest trauma in Syria. Violence was the most common cause of chest trauma rather than road traffic accidents in this series, this necessitates epidemiologic or multi-institutional studies to know to which degree violence contributes to chest trauma in Syria. The number of fractured ribs can be used as simple indicator of the severity of trauma. And we believe that significant neurotrauma, traffic accidents, hemodynamic status and GCS upon arrival, ICU admission, ventilator use, and complication of therapy are predictors of dismal prognosis.

    Full Text Available Background: Third molars are the teeth reported in the literature, that present more variability in number, shape and size. There is no information reported in the Colombian literature concerning the agenesis of the third molar in Colombians. This data may changes constantly from one population to another. This study was looking for agenesis of the third molars and performed on dental students at the Universidad del Valle. Objectives: Determine dental agenesis of the third molars and describe characteristics such as gender, arcade, and dental quadrants. Method: A descriptive study using 1824 periapical radiographs of 456 people aged 16 to 25 years old. Results: The results showed that 96 students didn’t developed some or none of third molars, which corresponds to 21% agenesis of the studied population. No significant statistical differences were found on gender, in the mandible and maxilla, neither in the left and right sides Conclusion: The percentage of agenesis in this study is consistent with most of the reports in the literature, in populations from different parts of the world.
