    Full Text Available AIM: To determine attrition and predictors of academic success among medical students at University of Split, Croatia. METHODS: We analysed academic records of 2054 students enrolled during 1979-2008 period. RESULTS: We found that 26% (533/2054 of enrolled students did not graduate. The most common reasons for attrition were 'personal' (36.4%, transfer to another medical school (35.6%, and dismissal due to unsatisfactory academic record (21.2%. Grade point average (GPA and study duration of attrition students were significantly associated with parental education. There were 1126 graduates, 395 men and 731 women. Their average graduation GPA was 3.67±0.53 and study duration 7.6±2.44 years. During 5-year curriculum only 6.4% (42/654 of students graduated in time, and 55% (240/472 of students graduated in time after curriculum was extended to 6 years. Variables predicting whether a student will graduate or not were high school grades, entrance exam score and year of enrollment. Significant predictors of graduation grades were high school grades and entrance exam score. Entrance exam score predicted length of studying. CONCLUSION: Preadmission academic qualifications and year of enrollment predict academic success in medical school. More attention should be devoted to high attrition.

    Full Text Available Introduction: Toxic epidermal necrolysis and Stevens–Johnson syndrome are acute life-threatening mucocutaneous reactions to drugs. The aims of the study were to identify these drugs and characterize population prone to these reactions. Materials and Methods: Data including demographics, culprit drug, clinical characteristics, course of disease, treatment given, and therapeutic responses were retrospectively collected from medical records of 31 patients admitted to Department of Dermatology from January 2009 to December 2014. Results: Drugs most commonly involved in Stevens–Johnson syndrome were antimicrobials: ciprofloxacin, doxycycline, cefuroxime, trimethoprim, amoxicillin, clindamycin, co-trimoxazole (50% of patients and nonsteroidal anti-inflammatory drugs: ibuprofen, naproxen, metamizole, piroxicam (29% of patients. Drugs involved in toxic epidermal necrolysis were antimicrobials: sulfasalazine, co-trimoxazole, cefuroxime, clindamycin (71% of patients and anticonvulsants: lamotrigine (29% of patients. The comorbidities’ characteristic for the group of patients affected by toxic epidermal necrolysis were psychiatric and autoimmune disorders. The most common complication was infection. Two patients died and in both cases the cause of death was sepsis. Conclusion: The study indicates that in observed population drugs with the highest risk of most severe reactions are lamotrigine (anticonvulsant and antimicrobials (most commonly sulfonamides, therefore it is advisable to consider carefully administration of these drugs, especially to patients with history of autoimmune reactions.

    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.

    Full Text Available Background Differentiated thyroid cancers (DTC are abnormal tissues growing around the thyroid gland manifesting in various forms, they vary according to geographic locations and life style. Knowledge of different types of DTC is important in order to implement cost effective treatment strategies. Aims This study was aimed at establishing the types of thyroid cancers among DTC patients managed with radioiodine post-surgery in the Department of Nuclear Medicine at Dr George Mukhari Academic Hospital (DGMAH in South Africa. Methods A retrospective five year (2007–2013 review of patient files managed post-surgery in the Nuclear Medicine Department for various thyroid diseases. A total of 51 patient files were examined. Males and females who received at least a single treatment dose of radioiodine (I-131 qualified for the study thus excluding 26 patients treated for grave’s disease and 9 DTC patients who did not receive a dose of radioiodine. A pie chart was used for categorical variables of the subtypes of carcinomas. Results The follicular carcinoma was the leading malignancy: 8 /16; (50 per cent; followed by the papillary carcinomas amounting to 6/16; (37.5; only one patient was managed for the Hurtle cell carcinoma; 1/16 (6.25 per cent and also one patient for poorly differentiated follicular carcinoma, 1/16; (6.25 per cent. Conclusion Follicular carcinoma was found to be the most common type of DTC managed at DGMAH followed by papillary carcinoma. However, the Hurtle cell carcinoma and the poorly differentiated follicular carcinomas were found to be rare.

    2006-01-01

    To answer two research questions: First, can previously identified factors relating to academic performance be used to predict first-year academic success for students undertaking a newly developed and vocationally oriented prehospital care course delivered in a rural setting? Second, can the study's findings be used to develop appropriate student selection criteria to assist in the admission of students into relevant tertiary studies or the prehospital care industry? A retrospective review of all first-year, on-campus prehospital care students enrolled in a vocational course at a rural Australian university from 1998 to 2001 was conducted. Six predictors of academic performance were examined, namely: University Admission Index (UAI), postsecondary educational qualifications, student entry type (traditional or mature-aged), previous health-related experience, gender, and background (rural or urban). Three dependent variables assessed academic performance: grade point average (GPA) of students who completed all required first-year subjects, GPA of students who completed at least one subject in the first year, and the student's ability to successfully complete the first year. UAI > 50, previous health-related experience, postsecondary educational qualifications, background, student entry type, and gender were all found to be significant predictors of first-year academic performance in selective cohorts. In addition, a combination of predictors produced higher GPAs than did any single predictor. Academic performance of first-year students in the prehospital care discipline can be predicted given the appropriate selection variables. Admission selection can be assisted with the generated Student Selection 001.

    The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and the conducted treatment were analyzed. Odontogenic infections were defined as pulpitis, apical and marginal periodontitis, abscesses and pericoronitis. A total of 2,058 out of 4,209 emergency patients suffered from odontogenic infections. The majority (45.0%) had an apical periodontitis, 20.8% abscesses, 17.3% a marginal periodontitis, 16.3% a pulpitis and 5.8% a pericoronitis. Mean age was 37.5 ± 17.0 years standard deviation (SD) (1.2-96.4). Most patients were 20 to 29 years (24.6%), followed by the age group of 30 to 39 year old patients (21.0%). Males were affected more frequently (55.5%) than females (45.5%). Most of the patients (64.5%) of the patients received a dental or surgical treatment. Antibiotics were prescribed in 31.7% of cases. Amoxicillin was the most common prescribed antibiotic (54.5%). Odontogenic infections represent one of the main reasons for consulting the emergency service. Due to the high number of cases and the severe complications, dentists have to be familiar with the surgical management of odontogenic infections as well as the appropriate use of antibiotics. Nearly half of all patients who sought, treatment in the emergency service had an odontogenic infectious disease. This should be considered for the organization and planning of the service.

    Complications from diabetes mellitus including major lower extremity amputation may have significant impact on a patient's mortality. This study determined what impact the addition of a limb salvage and diabetic foot program involving podiatry had at an academic institution over 16years by analyzing high-low amputation ratio data. The high-low amputation ratio in the diabetic population who underwent non-traumatic amputation of the lower extremity was retrospectively evaluated at an academic institution via cohort discovery of the electronic medical record and analysis of billing over 16years. We directly compared two eras, one without podiatry and one with a podiatry presence. It was found that with the addition of a podiatry program, limb salvage rates significantly increased (R(2) (without podiatry)=0.45, R(2) (with podiatry)=0.26), with a significant change in both the rate of limb salvage per year (-0.11% per year versus -0.36% per year; pamputation ratio (0.89 without podiatry to 0.60 with podiatry). Of note, approximately 40 major lower extremity amputations were avoided per year with the addition of a podiatry program (pamputations can be avoided and more limbs can be salvaged, thus preventing some of the moribund complications from this condition.

    This retrospective case review examines farm tractor-related deaths in the Commonwealth of Virginia for an 11-year period, from 1997 to 2007. This study compares decedent's demographic information, toxicology results, and medical histories.A vast majority of farm tractor-related deaths were male (98%) and white (91%). The average age was 60 years with most deaths occurring between the ages of 40 and 80 years. Ethanol use was observed in 9% of all cases with 7% of cases being more than 0.08% wt/vol ethanol, which is the legal limit in Virginia to operate a motor vehicle.The more mountainous, Western District Office of the Chief Medical Examiner composed 60% of total cases with 43% of these western cases related to tractor use on a natural slope or incline. The deaths in other districts were all less than 13% natural slope or incline related, reflecting the topography of these areas.These findings confirm much of what observation would suggest; accidents with farming tractors typically involve older white men. Operating a tractor on steep inclines is dangerous as many tractors do not have adequate rollover protection. The use of ethanol is dangerous when using any heavy equipment.This study provides an initial look at tractor-related deaths in Virginia, and more research is needed in this area to improve safety mechanisms on this machinery.

    Full Text Available Background: "Mental disorder" is the most common used term in the modern life and the main reason behind this may be the mechanical way of life or stress and strain among youth. Aim: To find the pattern of mental disorders of hospitalized patients in a medical college hospital from 1 st April 2005 to 31 st March 2010. Settings and Design: A retrospective study conducted among the patients admitted with mental disorders in a medical college hospital from 1 st April 2005 to 31 st March 2010. Materials and Methods: Data collected from the registers maintained in the medical records department. Statistical Analysis: Z test is used for the comparison of proportions. Results: A total of 7908 mental disorder cases reported in the medical college hospital, 5564 (70.36% were males and 2344 (29.64% were females. Most cases occurred in the age group of 30-44 years. Mental disorder was more among females than males in 0-29 years and ≥ 60 years, but in 30-59 years males were more. In each year, mental disorders were reported more in males than females. Of the cases, most of them were mood disorders. Mental and behavioral disorders due to psychoactive substance use were more among males but schizophrenia, delusional disorders, mood disorders, stress-related disorders, mental retardation, and so on were more among females. Conclusion: Mood disorder was the most occurred mental disorder and the next leading mental disorder was mental and behavioral disorders due to psychoactive substance use. Counseling can be helpful for preventing most of the mental disorders. Improve the mental health care facilities will be the solution for controlling the mental disorders.

    This study focuses on the epidemiology, clinical manifestations, risk factors, diagnosis and outcome of all cases of central nervous system (CNS) fungal infections in a tertiary center. Medical records of 18 patients of culture-proven CNS fungal infections were retrospectively reviewed from 2000 to 2007, including 12 isolated from the cerebrospinal fluid (CSF) and seven from tissue biopsy. Patient demographic data included 10 males and eight females. The mean age was 55 years (range: 24-89 years). All but one patient were immunocompromised. Fungal organisms isolated from CSF included: Cryptococcous neoformans (8 patients), Coccidioides immitis (3 patients), and Aspergillus versicolor (1 patient). Histopathology of seven biopsy cases revealed groups of pigmented golden-brown fungal forms in three cases; three cases showed septate fungi, two of which had melanin in their walls; and one case showed multiple round spherules. These cases on microbiological cultures grew Coccidioides immitis (1 patient), Aspergillus fumigatus (1 patient), Cladophialophora bantiana (2 patients), Fonsecaea monophora (1 patient) and Scedosporium apiospermum (2 patients). Five of the seven fungal organisms isolated from tissue biopsies were dematiaceous fungi. Twelve patients died after a period of a few weeks to months, two were lost to follow-up, and four are alive with severe neurological sequelae. CNS fungal infections in our cohort were more common in patients post-transplant and with hematologic malignancies. In our series, rare dematiaceous fungi are emerging agents for cerebral mycosis. The outcome of CNS fungal infections is poor despite vigorous antifungal therapy.

    Ameloblastoma is the most common epithelial odontogenic tumor. It may show locally invasive behavior resulting in recurrence and malignancy. Therefore, appropriate diagnosis of this tumor is necessary. The aim of this study was to evaluate clinicopathological characteristics of ameloblastomas in an Iranian population. We present a 40-year retrospective study of patients diagnosed from 1971 to 2010 in the Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, Mashhad, Iran. Information gathered from patient records included age, gender, tumor location and histologic type. The frequency of odontogenic tumors among all lesions was 2.08% and ameloblastoma with 88 samples demonstrated the greatest prevalence (41.5%). Regarding gender, 60% of samples occurred in males. The mean age of studied patients was 33.02± 15.74 years with a peak of occurrence in the third decade of life. The most frequent location of tumor was the mandibles (93.2%). Eighty five (96.6%) tumors were recorded as benign and 3 (3.4%) as malignant. Of benign tumors, 62 (72.9%), 20 (23.5%) and 3 (3.6%) cases were of conventional, unicyctic and peripheral types, respectively. In contrast to most previous studies, the most common histologic subtype in the present study was plexiform. Knowledge of the incidence of ameloblastoma and its clinicopathologic features including most common location, gender and age distribution in different ethnogeographic backgrounds is necessary for accurate diagnosis and proper treatment.

    We explored the relation between the causes of facial injuries in equestrians and the presence or absence of associated injuries. Over a 5-year period we retrospectively reviewed all patients who presented to the John Hunter Hospital, New South Wales, with facial injuries that had resulted from activity with horses. We analysed the rates of hard and soft tissue injuries, and of associated injuries by sex and mechanism. A total of 85 patients were included (50 female and 35 male) with an age range of 2-88 years. There was a significant difference in the rate of maxillofacial and associated injuries when groups were analysed for sex and mechanism of injury. Facial injuries caused by falling from a horse were more often associated with other injuries in men than in women (p<0.05), and men were 4 times more likely to present with associated injuries than women (OR 3.9; 95% CI 1.1 to 14) We also found significant differences in the rates of facial fracture. Women who had been kicked by a horse were more likely to sustain bony injuries than men (p<0.05). Our data confirm the association between kicks and facial fracture, and this may provide an impetus for the development of appropriate protective equipment. Patients who sustain facial injuries when falling from a horse often present with associated injuries and this has practical implications for clinicians involved in their management.

  3. Verb-Noun Collocation Proficiency and Academic Years

    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.

    Full Text Available Background. Leprosy is a chronic infectious disease that presents with varying dermatological and neurological symptoms. The leprosy reactions occur over the chronic course of the disease and lead to extensive disability and morbidity. Objective. To analyze and identify the risk factors which contribute to leprosy reactions. Methods. In a retrospective study, we reviewed the medical records of leprosy patients registered at the leprosy clinic, Ramathibodi Hospital, Thailand, between March 1995 and April 2015. One hundred and eight patients were included; descriptive analysis was used for baseline characteristics and a binary logistic regression model was applied for identifying risk factors correlated with leprosy reactions. Results. Of the 108 cases analyzed, 51 were male and 57 were female. The mean age of presentation was 45 years. The borderline tuberculoid type was the most common clinical form. Leprosy reactions were documented in 61 cases (56.5%. The average time to reaction was 8.9 months. From multivariate analysis, risk factors for leprosy reactions were being female, positive bacillary index status, and MB treatment regimen. Conclusions. Leprosy reactions are common complications in leprosy patients. Being female, positive bacillary index status, and multibacillary treatment regimen are significantly associated with the reactions. Early detection in cases with risk factors followed by appropriate treatment could prevent the morbidity of leprosy patients.

    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

The LOS for all inpatients has changed dramatically from 1970 (average LOS = 7.8 days) through solidly between 2005 and 2012 (average LOS = 4.5 days in 2012) despite a significant increase in the average age of hospital inpatients (; ). For patients 65 years and older, who comprised 38% of all inpatients, the decrease has been more drastic: from 12.6 days in 1970 to 5.5 days in 2005-2010 ().With the exception of hospitalists and case management staff, acute care hospitals have essentially doubled productivity without adding additional direct care full-time equivalents! Described in terms of "low-hanging" to "high-hanging" fruit, this article outlines the classic methods used to reduce LOS and concludes with some implications of LOS for health care reform. The U.S. health system could not have accomplished this feat without case managers and social workers. Acute care services should be very proud of their achievements and use their reputation to empower their work for the next frontier, which will be reducing cost per case, especially in risk contracts. Everything old seems new again.

    OBJECTIVE: A group of diseases in the scrotum setting forth by the sudden swelling and redness and pain consist of acute scrotal pathologies. The most common causes of acute scrotum in children are epididymitis, epididymo-orchitis, orchitis, testicular torsion, torsion of the appendix testis, incarcerated inguinal hernia and traumatic hydro/hematocele. In this study; we aim to evaulate patients with acute scrotal pathologies who were interned in our department. METHODS: All hospital data of cases who were interned at our deparment due to acute scrotum in between June 2010-June 2014 were evaluated retrospectively. Cases with incarcerated inguinal herni were excluded in this study. RESULTS: In a 4-year-period 114 cases were interned in our department with acute scrotum. Mean age of the patients was 7.6±4.577 years (min: 1m-max: 18yrs). Doppler US was performed in 112 patients to evaluate the blood flow while in 2 patients applied after normal office hours were evaluated without Doppler US and operated under emergency conditions. The patients had received diagnosis of epididymitis/epididymo-orchitis/orchitis (n=83 cases; 72.8%), testicular torsion (n=24; 21.1%), torsion of the appendix testis (n=2; 1.8%) with and traumatic hydrocele/ hematocele (n=5; 4.4%). While detorsion was performed in 18 (75%) cases with testicular torsion and orchiectomy in 6 (25%) cases. Histopathological evaluation of orchiectomy specimens revealed hemorrhagic necrosis and hemorrhagic infarction or ischemic changes. Normal testicular size and vascularity were detected in 11 (61.1%) cases with detorsioned testis as detected by follow-up Doppler US. Late orchiectomy was performed in 7 cases (38.9%) with complete atrophy due to lack of blood supply. CONCLUSION: Although Doppler US is very helpful for differential diagnosis of patients with acute scrotum who applied early period, if Doppler US will lead to a waste of time, direct surgery without delay will reduce the risk of testicular loss.

    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

    Electrical burns are the third most common cause of burn injuries, after scald and flame burns. In spite of decreasing mortality rates as advancements are made in treatment modalities and medical equipment, significant complications and socioeconomic consequences still accompany electrical burns. Analyzed in the present study were data from patients hospitalized for electrical burns between 2008 and 2012 in the Samsun Training and Research Hospital, the only burn care center in the Black Sea region of Turkey. Data from 94 patients (84 males, 10 females) hospitalized for electrical burns between 2008 and 2012 were retrospectively evaluated. Patient age, gender, occupation, presence of coexisting trauma, burn degree, burned percentage of total body surface area (TBSA), voltage of the electric current (low or high), medical cost (per day and total), and infection rates were analyzed. Mean patient age was 26.4±13.2 years. Ten patients were female (10.6%) and 84 were male (89.4%). High-voltage burns were sustained by 47 patients (50%) and low-voltage burns by 42 (44.7%); the remaining 5 were flash burns. Mean burned TBSA was 21.8±19.8% in high-voltage injuries and 11.9±6.9% in low-voltage injuries. Seven patients had accompanying soft tissue lacerations, major bone fractures, or epidural hematomas. Findings of infection were encountered in 31 patients (32.9%), and appropriate treatments were initiated according to culture results. Mean duration of hospitalization was 21.3±19.8 days in patients with high-voltage burns and 8.6±6.2 days in patients with low-voltage burns. Mean hospital stay was 2.5-fold longer, and total medical costs were 4-fold higher in patients with high-voltage burns. Young adult males who were injured in industrial accidents constituted the majority of high-voltage burn patients. Incidence of these injuries may be reduced by improvements in training regarding the safe use of electrical devices, and correct installation and safe maintenance of

    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.

    Full Text Available 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.

    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.

    We sought to describe the incidence of acute pyelonephritis in pregnancy, and to assess its association with perinatal outcomes in an integrated health care system. A retrospective cohort study was performed using medical records on 546,092 singleton pregnancies delivered in all Kaiser Permanente Southern California hospitals from 1993 through 2010. These medical records include the perinatal service system along with inpatient and outpatient encounter files. Adjusted odd ratios (ORs) and 95% confidence intervals (CIs) were used to estimate associations. The incidence of acute antepartum pyelonephritis was 0.5% (2894/543,430). Women with pyelonephritis in pregnancy were more likely to be black or Hispanic, young, less educated, nulliparous, initiate prenatal care late, and smoke during pregnancy. Pregnancies of women with pyelonephritis compared to those without were more likely to be complicated by anemia (26.3% vs 11.4%; OR, 2.6; 95% CI, 2.4-2.9), septicemia (1.9% vs 0.03%; OR, 56.5; 95% CI, 41.3-77.4), acute pulmonary insufficiency (0.5% vs 0.04%; OR, 12.5; 95% CI, 7.2-21.6), acute renal dysfunction (0.4% vs 0.03%; OR, 16.5; 95% CI, 8.8-30.7), and spontaneous preterm birth (10.3% vs 7.9%; OR, 1.3; 95% CI, 1.2-1.5). Most of the preterm births occurred between 33-36 weeks (9.1%). We characterize the incidence of pyelonephritis in an integrated health care system where routine prenatal screening for asymptomatic bacteriuria is employed. Maternal complications are commonly encountered and the risk of preterm birth is higher than the baseline obstetric population. Copyright © 2014 Mosby, Inc. All rights reserved.

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.

  11. Organic geochemistry - A retrospective of its first 70 years

    Science.gov (United States)

    Kvenvolden, K.A.

    2006-01-01

    Organic geochemistry had its origin in the early part of the 20th century when organic chemists and geologists realized that detailed information on the organic materials in sediments and rocks was scientifically interesting and of practical importance. The generally acknowledged "father" of organic geochemistry is Alfred E. Treibs (1899-1983), who discovered and described, in 1936, porphyrin pigments in shale, coal, and crude oil, and traced the source of these molecules to their biological precursors. Thus, the year 1936 marks the beginning of organic geochemistry. However, formal organization of organic geochemistry dates from 1959 when the Organic Geochemistry Division (OGD) of The Geochemical Society was founded in the United States, followed 22 years later (1981) by the establishment of the European Association of Organic Geochemists (EAOG). Organic geochemistry (1) has its own journal, Organic Geochemistry (beginning in 1979) which, since 1988, is the official journal of the EAOG, (2) convenes two major conferences [International Meeting on Organic Geochemistry (IMOG), since 1962, and Gordon Research Conferences on Organic Geochemistry (GRC), since 1968] in alternate years, and (3) is the subject matter of several textbooks. Organic geochemistry is now a widely recognized geoscience in which organic chemistry has contributed significantly not only to geology (i.e., petroleum geochemistry, molecular stratigraphy) and biology (i.e., biogeochemistry), but also to other disciplines, such as chemical oceanography, environmental science, hydrology, biochemical ecology, archaeology, and cosmochemistry.

    This paper analyses the role of academic preparation and learning strategies in the prediction of first-year Portuguese college students' academic achievement, considering students' sex and academic field attended. A sample of 445 first-year college students (68.5% female) from the University of Minho (25.8% enrolled in economics, 35.3% in science/technology, and 38.9% in humanities degrees) participated in the study. Students answered a questionnaire on learning strategies in the classroom at the end of the first semester, which consisted of 44 items organized in five dimensions: comprehensive approach, surface approach, personal competency perceptions, intrinsic motivation, and organization of study activities. Academic achievement (grade point average at the end of first year) and academic preparation (students' higher education access mark) were obtained through the academic records of the university. Results showed that academic preparation was the strongest predictor of first-year academic achievement, and only marginal additional variance was explained by learning strategies as assessed by the self-reported questionnaire. There were sex and academic field differences, but these variables do not seem strong enough to affect the results, although the different percentages of variance captured by each model and the different weights associated to higher education access mark, stimulate the use of these and/or other personal and contextual variables when analysing the phenomenon.

    Full Text Available Purpose. To determine the clinical features, microbial profiles, treatment outcomes, and prognostic factors for endogenous bacterial endophthalmitis (EBE. Methods. The medical records of 27 eyes of 21 patients diagnosed with EBE for 11 years were reviewed. Collected data included age, site of infection, visual acuities (VAs, microbial profiles, and treatment regimen. Results. The mean age was 68.5 years. Gram-positive organisms accounted for 76.2%, while gram-negative ones accounted for 19.0%. Staphylococcus aureus was the most common causative organism (52.3% of which 72.7% was methicillin-resistant S. aureus. A final VA of ≥20/40 was achieved in 44% and 20/200 or better was in 64%. Eyes with initial VA of ≥20/200 (P = 0.003 and focal involvements (P = 0.011 had significantly better final VA. Initial VA (P = 0.001 and the interval between onset of ocular symptoms and intravitreal antibiotic injection (P = 0.097 were associated with final VA in eyes receiving intravitreal antibiotics. Conclusions. EBE is generally associated with poor visual outcome; however the prognosis may depend on initial VA, extent of ocular involvement, and an interval between onset of ocular symptoms and intravitreal antibiotic injection. Early diagnosis and early intravitreal injection supplement to systemic antibiotics might lead to a relatively good visual outcome.

    Twenty-five years ago this month, Thomas Gold published a seminal manuscript suggesting the presence of a "deep, hot biosphere" in the Earth's crust. Since this publication, a considerable amount of attention has been given to the study of deep biospheres, their role in geochemical cycles, and their potential to inform on the origin of life and its potential outside of Earth. Overwhelming evidence now supports the presence of a deep biosphere ubiquitously distributed on Earth in both terrestrial and marine settings. Furthermore, it has become apparent that much of this life is dependent on lithogenically sourced high-energy compounds to sustain productivity. A vast diversity of uncultivated microorganisms has been detected in subsurface environments, and we show that H2, CH4, and CO feature prominently in many of their predicted metabolisms. Despite 25 years of intense study, key questions remain on life in the deep subsurface, including whether it is endemic and the extent of its involvement in the anaerobic formation and degradation of hydrocarbons. Emergent data from cultivation and next-generation sequencing approaches continue to provide promising new hints to answer these questions. As Gold suggested, and as has become increasingly evident, to better understand the subsurface is critical to further understanding the Earth, life, the evolution of life, and the potential for life elsewhere. To this end, we suggest the need to develop a robust network of interdisciplinary scientists and accessible field sites for long-term monitoring of the Earth's subsurface in the form of a deep subsurface microbiome initiative.

    To assess the impact on student performance of increased active learning strategies in a foundational pharmacokinetics course and a clinical pharmacokinetics course over an 8-year period. A foundational pharmacokinetics course with a lecture-with-active-learning (LAL) format was redesigned to a recitation-format (REC) using smaller groups of students (ie, the class divided into thirds) and eventually to a team-based learning (TBL) format. The lecture-based clinical pharmacokinetics course was redesigned to a case-based learning (CBL) format to encourage preclass preparation with class time used for application; this course format underwent minor redesigns over an 8-year period. An analysis of covariance (ANCOVA) was performed on examination scores in the clinical course based on foundational course format changes. End-of-semester student evaluations of the course were used as a secondary measure of impact. The highest grades in the clinical course were associated with the TBL format within the foundational course compared to LAL format (effect size 0.78). The REC format in the foundational course compared to LAL was associated with higher performance in the clinical course (effect size 0.50). Examination performance in the clinical course had a small increase when the foundational course was transitioned from the REC format to the TBL format (effect size 0.27). There was a trend within the foundational course that overall student ratings of the course decreased with enhanced self-directed learning; there was no change in overall ratings of the clinical course. Increasing the amount of active learning within the foundational pharmacokinetics course increases performance in the clinical course but this increase in performance may be associated with decreases in student evaluations of the foundational course.

    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.

    30 years have passed since the second Soviet research Lunokhod-2 rover landed on the Moon on January 16, 1973 within the framework of the Luna-21 mission. Scientific explorations of the lunar surface and space, begun with the Lunokhod-1 rover (1970-1971), were continued with Lunokhod-2. Creation of Lunokhod-1 and Lunokhod-2 marked realization of direction on study of planets using mobile self-propelled robots. Other direction connected with using planetary rovers to transport astronauts, scientific equipment and weights was realized as a result of creation of the American LRV lunar rover. Astronauts during Apollo-15 (1971), Apollo-15 (1972) and Apollo-15 (1972) missions used it. Programs of operation for Lunokhod-1,-2 on the Moon envisaged investigations of topographic and morphological peculiarities of the terrain, determination of the chemical composition and physical and mechanical properties of soil, experiments on the laser detection and ranging of the Moon and, etc. Successful fulfilment of programs was ensured, to a considerable extent, with the self-propelled chassis developed at VNIITRANSMASH to order of the Lavochkin Scientific and Production Association (NPOL). The chassis, on the one hand, ensured necessary cross-country ability for Lunokhod-1,-2, on the other hand, it was as the independent scientific instrument, which provided investigation as temperature measurement of the lunar surface, surface topography and craters distribution, physical and mechanical properties of soil with the special PROP instrument equipped with the penetrometer, chassis traction-cohesive characteristics, upper surface layer by a character its deformation by the mover, etc. A number of improvements of Lunokhod-2 improving its operating characteristics were performed on the basis of results of Lunokhod-1 operation. Lunokhod-1,-2 operation confirmed that automatic mobile robots can be used as effective means for studying planets and their satellites. At the same time, an

    Detecting patterns of maternal drinking that place fetuses at risk for fetal alcohol spectrum disorders (FASDs) is critical to diagnosis, treatment, and prevention but is challenging because information on antenatal drinking collected during pregnancy is often insufficient or lacking. Although retrospective assessments have been considered less favored by many researchers due to presumed poor reliability, this perception may be inaccurate because of reduced maternal denial and/or distortion. The present study hypothesized that fetal alcohol exposure, as assessed retrospectively during child adolescence, would be related significantly to prior measures of maternal drinking and would predict alcohol-related behavioral problems in teens better than antenatal measures of maternal alcohol consumption. Drinking was assessed during pregnancy, and retrospectively about the same pregnancy, at a 14-year follow-up in 288 African-American women using well-validated semistructured interviews. Regression analysis examined the predictive validity of both drinking assessments on pregnancy outcomes and on teacher-reported teen behavior outcomes. Retrospective maternal self-reported drinking assessed 14 years postpartum was significantly higher than antenatal reports of consumption. Retrospective report identified 10.8 times more women as risk drinkers (≥ one drink per day) than the antenatal report. Antenatal and retrospective reports were moderately correlated and both were correlated with the Michigan Alcoholism Screening Test. Self-reported alcohol consumption during pregnancy based on retrospective report identified significantly more teens exposed prenatally to at-risk alcohol levels than antenatal, in-pregnancy reports. Retrospective report predicted more teen behavior problems (e.g., attention problems and externalizing behaviors) than the antenatal report. Antenatal report predicted younger gestational age at birth and retrospective report predicted smaller birth size

    Background An estimated 136 000 concussions occur per academic year in high schools alone. The effects of repetitive concussions and the potential for catastrophic injury have made concussion an injury of significant concern for young athletes. Purpose The objective of this study was to describe the mechanism of injury, symptoms, and management of sport-related concussions using the High School Reporting Information Online (HS RIO) surveillance system. Study Design Descriptive epidemiology study. Methods All concussions recorded by HS RIO during the 2008–2009 academic year were included. Analyses were performed using SPSS software. Chi-square analysis was performed for all categorical variables. Statistical significance was considered for P concussions were recorded. The most common mechanism (76.2%) was contact with another player, usually a head-to-head collision (52.7%). Headache was experienced in 93.4%; 4.6% lost consciousness. Most (83.4%) had resolution of their symptoms within 1 week. Symptoms lasted longer than 1 month in 1.5%. Computerized neuropsychological testing was used in 25.7% of concussions. When neuropsychological testing was used, athletes were less likely to return to play within 1 week than those for whom it was not used (13.6% vs 32.9%; P < .01). Athletes who had neuropsychological testing appeared less likely to return to play on the same day (0.8% vs 4.2%; P = .056). A greater proportion of injured, nonfootball athletes had computerized neuropsychological testing than injured football players (23% vs 32%; P = .02) Conclusion When computerized neuropsychological testing is used, high school athletes are less likely to be returned to play within 1 week of their injury. Concussed football players are less likely to have computerized neuropsychological testing than those participating in other sports. Loss of consciousness is relatively uncommon among high school athletes who sustain a sport-related concussion. The most common mechanism is

    To determine associations between admission markers of socioeconomic status, transitioning, bridging programme attendance and prior academic preparation on academic outcomes for indigenous Māori, Pacific and rural students admitted into medicine under access pathways designed to widen participation. Findings were compared with students admitted via the general (usual) admission pathway. Retrospective observational study using secondary data.  6-year medical programme (MBChB), University of Auckland, Aotearoa New Zealand. Students are selected and admitted into Year 2 following a first year (undergraduate) or prior degree (graduate). 1676 domestic students admitted into Year 2 between 2002 and 2012 via three pathways: GENERAL admission (1167), Māori and Pacific Admission Scheme-MAPAS (317) or Rural Origin Medical Preferential Entry-ROMPE (192). Of these, 1082 students completed the programme in the study period. Graduated from medical programme (yes/no), academic scores in Years 2-3 (Grade Point Average (GPA), scored 0-9). 735/778 (95%) of GENERAL, 111/121 (92%) of ROMPE and 146/183 (80%) of MAPAS students graduated from intended programme. The graduation rate was significantly lower in the MAPAS students (pMAPAS. Multiple regression analyses identified three key predictors of better academic outcomes: bridging programme attendance, admission as an undergraduate and admission GPA/Grade Point Equivalent (GPE). Attending local urban schools and higher school deciles were also associated with a greater likelihood of graduation. All regression models have controlled for predefined baseline confounders (gender, age and year of admission). There were varied associations between admission variables and academic outcomes across the three admission pathways. Equity-targeted admission programmes inclusive of variations in academic threshold for entry may support a widening participation agenda, however, additional academic and pastoral supports are recommended. © Article

    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. 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. 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. 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.

    The purpose of this study is to identify laryngeal symptoms and injuries in self-extubated patients. A retrospective chart review was conducted to identify symptoms and clinical findings associated with self-extubation. A novel scoring system was developed and used to quantify these findings. Symptom score included all symptoms that patients reported after self-extubation. Clinical score consisted of laryngeal findings visualized on nasopharyngeal laryngoscopy. Finally, a total self-extubation score was calculated as the sum of the symptom and clinical scores. Additionally, duration of intubation and endotracheal tube size were correlated with these scores. Sixty (n = 60) patients who self-extubated in our institution's intensive care unit were identified. Average calculated symptom, clinical, and total self-extubation scores were 0.92, 1.43, and 2.35, respectively. The most common symptom observed was hoarseness (62%), while the most common clinical finding was posterior laryngeal edema (58%). A significant positive correlation was found between duration of intubation and both symptom score and total self-extubation score (r = 0.314, P = .008 and r = 0.223, P = .05, respectively). Symptom score predicted clinical score with a significant positive correlation present (r = 0.278, P = .02). This study demonstrates that the majority of self-extubated patients have laryngeal symptoms and clinical findings. A comprehensive, multidisciplinary evaluation is warranted for self-extubations.

In the USA, Graunke and Woosley (2005: 367) indicate that college sophomores (second years) face academic difficulties, but this receives little attention in the literature. Economics is an elective subject for second-year students at Stellenbosch University. The acad...

    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 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

    Internalizing and externalizing problems are associated with poor academic performance, both concurrently and longitudinally. Important questions are whether problems precede academic performance or vice versa, whether both internalizing and externalizing are associated with academic problems when simultaneously tested, and whether associations and their direction depend on the informant providing information. These questions were addressed in a sample of 816 children who were assessed four times. The children were 6-10 years at baseline and 14-18 years at the last assessment. Parent-reported internalizing and externalizing problems and teacher-reported academic performance were tested in cross-lagged models to examine bidirectional paths between these constructs. These models were compared with cross-lagged models testing paths between teacher-reported internalizing and externalizing problems and parent-reported academic performance. Both final models revealed similar pathways from mostly externalizing problems to academic performance. No paths emerged from internalizing problems to academic performance. Moreover, paths from academic performance to internalizing and externalizing problems were only found when teachers reported on children's problems and not for parent-reported problems. Additional model tests revealed that paths were observed in both childhood and adolescence. Externalizing problems place children at increased risk of poor academic performance and should therefore be the target for interventions.

    Full Text Available On August 1, 2009, the global Collaboratory for the Study of Earthquake Predictability (CSEP launched a prospective and comparative earthquake predictability experiment in Italy. The goal of this CSEP-Italy experiment is to test earthquake occurrence hypotheses that have been formalized as probabilistic earthquake forecasts over temporal scales that range from days to years. In the first round of forecast submissions, members of the CSEP-Italy Working Group presented 18 five-year and ten-year earthquake forecasts to the European CSEP Testing Center at ETH Zurich. We have considered here the twelve time-independent earthquake forecasts among this set, and evaluated them with respect to past seismicity data from two Italian earthquake catalogs. We present the results of the tests that measure the consistencies of the forecasts according to past observations. As well as being an evaluation of the time-independent forecasts submitted, this exercise provides insight into a number of important issues in predictability experiments with regard to the specification of the forecasts, the performance of the tests, and the trade-off between robustness of results and experiment duration. We conclude with suggestions for the design of future earthquake predictability experiments.

    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.

    2008-01-01

    Conclusion: Our results support the prerequisite of a minimum GPA in the premedical year before proceeding to the higher levels. The GPA of premedical year is a useful predictor of students who need close monitoring and academic support. The use of GPA in the premedical year for admission into medical colleges should help optimize the use of resources and reduce student wastage.

  10. 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.

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

    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. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Full Text Available Mycotic infections of the skin, hair and nails are disorder with high prevalence. Dermatophytes are the most frequently etiologic agents followed by yeasts and non-dermatophyte moulds. The geographic distribution is variable because of migration, lifestyle and socio-economics conditions. In this study, based on ours three years retrospective data analysis, we evaluate the epidemiology of etiologic agents, diagnosis and management of superficial mycoses. Our data and our experience suggest the importance of this microbiological diagnosis and the role of the Clinical Microbiologist to assess with Dermatologist and Primary Care Phyisician an appropriate diagnostic and therapeutic plan.

    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.

    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.

    1990-01-01

    On the eleventh anniversary of his Editorship of JDC, Dr. George Teuscher took stock of the state of the Journal, noting progress made and challenges ahead, writing that, "A good journal cannot ride on its reputation... Constant effort to improve, resourcefulness, and prolific reading and study are required of the editor of a prestigious journal." He has written extensively on the importance of writing and effective communication in the face of an information explosion, stating that, "The journal is still the best means of presenting new information to the professions." Writing a note of encouragement to the editor of a new dental journal, he observed, "Of course the dental and medical literature can boast of some great editors, who earned their reputations because they were able to apply intelligence, writing ability, knowledge of the scientific method, and imagination to a new undertaking." After twenty-one years, it is safe to say that Dr. Teuscher is such an Editor; he has filled our minds with knowledge and our hearts with wisdom; he has reminded us of the best that is in us; he has helped us to feel the anguish of the afflicted and oppressed; he has brought knowledge and skill to help the infirm: and he has taught us to stand in awe before the mystery of being.

    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

    The aim of the present clinical retrospective study was to evaluate the long-term survival and clinical performance of veneered lithium disilicate single restorations in anterior and posterior areas after up to 11 years. Following a rigid protocol, 275 lithium disilicate single crowns (35 IPS Empress II and 240 e.max Press) were cemented over 11 years, in 106 patients, using an adhesive technique; of these 106 were anterior (38.5%) and 169 posterior (61.5%) teeth. Teeth receiving endodontic therapy and composite reconstruction (50%) and teeth with preexisting metalceramic crowns, called prosthetic retreatments (PR; 65%), were included as well. Of the 106 patients enrolled in the study, 25 (23.5%) were diagnosed with bruxism habits, and 7 of these patients (6.6% of all patients) received full-mouth single lithium disilicate restorations (FMR). The exclusion criteria for this retrospective clinical study were: monolithic lithium disilicate crowns, teeth with cast post and cores, implant-supported all-ceramic crowns, active periodontitis, and/or poor oral hygiene. Clinical reevaluation was performed by the clinicians who prepared and luted them during maintenance appointments between January 2012 and October 2013. Number of restoration failures and characteristics of failures were recorded. Marginal adaptation and marginal discoloration were evaluated based on the Cvar-Ryge criteria. The overall cumulative survival rate was 98.2%. The failures recorded were the result of either mechanical failure or debonding. Five crowns failed mechanically-three because of chipping and two because of core fracture-and were replaced. None of the failed crowns was associated with the bruxers with FMR. A total of 15 crowns debonded (5.5% of all crowns); however, 11 belonged to the same patient who had endodontically treated and reconstructed abutments. In this retrospective clinical evaluation of up to 132 months, veneered lithium disilicate single crowns had a low failure rate.

    Full Text Available Background: In our institute, about 10% of total cancer is female breast cancer. This analysis was performed to check triple negativity among these patients with their survival strength up to 5 years in relation to different age groups, stage and chemotherapy protocols. Materials and Methods: 208 immunohistochemistry proved triple negative breast cancer patients registered and treated until 2008 were retrospectively selected for the study. Overall survival up to 5 years was observed on the basis of stage, different age groups and chemotherapy regimens. All patients had undergone surgery, conventional external beam radiation therapy and adjuvant chemotherapy. The survival analyses were performed using the Kaplan-Meier method. Results: The majority of patients (41% were in the age group 21-30 years. Stage IV was seen in 18% of the patients at diagnosis and mainly in 21-40 years age group. Only 3% of females were >70 years age and were of Stage I and II. Overall 5 year survival in Stage I in Cyclophosphamide, Adriamycin/Epirubicin, 5-Flurouracil group was 37.5% as compared with Docetaxel/Paclitaxel, Epirubicin group 93% (P < 0.0001. Conclusion: Triple negativity in North-West India is about 11.8%. We observed it in younger patients mainly with highly aggressive behaviors. Taxane based chemotherapy gives better result as compared with anthracycline based regimens in all stages.

    The purpose of this retrospective study was to evaluate the 4-year outcome of endodontic microsurgery using two different magnification devices. One-hundred and two teeth in 65 patients were included according to specific selection criteria. Endodontic surgery was performed under surgical microscope as magnification device in 63 teeth in 36 patients, while 39 teeth in 29 patients were treated under magnifying loupes. Thirteen patients did not attend the 4-year follow up. The overall success rate on a patient basis was 91.7% at the 1-year and 90.5% at the 4-year follow up for the group using loupes, while for the group using microscope it was 91.4% at the 1-year and 93.3% at the 4-year follow up. The relative risk was 2.07 (95% confidence interval: 0.31, 13.95) in favour of the group in which microscope was used. No statistically significant difference was found in the treatment outcomes relating to the type of magnification device. © 2011 The Authors.

    Long-term data regarding survival and crestal bone loss for Replace Select Tapered implants (Nobel Biocare AB, Gothenburg, Sweden) are lacking. The study aims to present the 5-year outcomes from a retrospective analysis of Replace Select Tapered implants placed and restored in consecutive patients. A total of 88 consecutive patients (32 male, 56 female, mean age 65 ± 12 years) treated by one clinician (PP) were clinically and radiographically evaluated during at least 5 years of function. A total of 271 dental implants (Replace Select Tapered, Nobel Biocare AB) with an oxidized surface (TiUnite, Nobel Biocare AB) had been placed in both jaws (228 in the maxilla, 43 in the mandible). The majority of implants were placed in healed sites (n = 244), while 27 implants were immediately placed in extraction sockets. The majority of implants (n = 262) healed for 3 to 4 months prior to loading, and nine implants were immediately loaded. A total of 121 implant-supported restorations were delivered; 42 single tooth replacements, 61 fixed partial bridges, 14 fixed full bridges, and 4 fixed partial implant-tooth connected bridges. The marginal bone level was measured in intraoral radiographs taken after surgery (baseline), and after 1, 2, 3, 4, and 5 years. Fifty-one patients with 160 implants were followed throughout the study. One implant failed at healing abutment connection 4 months after insertion, resulting in a cumulative survival rate of 99.6%. The average crestal bone loss was 0.9 ± 1.6 mm after 1 year and 0.1 mm ± 2.4 after 5 years. There were 14.8% of measured implants that showed more than 2 mm and 5.2% more than 3 mm bone loss after 5 years, with no progression since the 1-year examination. One patient (2.0%) treated with six implants presented with significant crestal bone loss and recurrent peri-implant purulent infections at all implants. The present retrospective 5-year study showed high survival rate and steady crestal bone

    Appendicitis in older adults may present as the first sign of underlying colorectal cancer. We aim to determine whether there was a difference in the rate of diagnosis of colorectal carcinoma for patients ≥45 years following a presentation with appendicitis, compared with New Zealand standardised rates. Retrospective study of patients ≥45 years with a confirmed diagnosis of appendicitis from 2003 to 2015 inclusive. The rate of colorectal carcinoma diagnosed during the 36-month follow-up period was calculated and compared to standardised rates, as per the New Zealand cancer registry. Six hundred and twenty-nine patients were included for analysis, 15 had a diagnosis of colorectal cancer in the follow-up period. Patients ≥45 years had a 6.3-fold (CI 3.6-10.2) increased risk of colorectal carcinoma than predicted given the population demographics. Those patients aged between 45-60 years had a 17-fold (95% CI 8-32.2) increased standardised risk ratio. This is the first study of its kind conducted in Australasia. This study found patients ≥45 years who present with appendicitis have significantly increased risk of underlying colorectal cancer. Until further research is conducted the authors recommend clinicians consider colonic investigation for older adults following a diagnosis of appendicitis.

    To address the academic gap (or lack of adequate training and programs) between 4- and 6-year pharmacy programs and suggest methods for reducing this gap and to evaluate pharmacists' perceptions of preceptorship. We surveyed a convenience sample of 200 community pharmacists who graduated from a 4-year program who were participating in a continuing education program for clinical pharmacy as organized by the Daejeon branch of the Korea Pharmaceutical Association in 2011. Twenty-one questions were asked about the academic gap, needs for an education program, preceptorship, and medication therapy management services. International precedents were examined through a literature review to glean ideas of how to bridge the academic gap between the 4- and 6-year programs. In total, 132 pharmacists answered the survey (return rate=66.0%). The survey findings included problems caused by the academic gap, high need for an adequate education program, low acceptability of preceptorship, and the possibility of medication therapy management services. US-based, non-traditional PharmD programs and new curriculum-support training in Japan provided examples of how the academic gap has been successfully bridged. Nationwide efforts and government support are urgently required to close the academic gap, and experiential education should be included in transitional programs for 4-year pharmacy program pharmacists.

    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 used the deidentified 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 4.7 per 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 (51 per cent than Indigenous children (2 per cent 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.

    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.

    Aim The objective of our review is to investigate the association between dermatomyositis patients and nasopharyngeal carcinoma (NPC) together with the clinical presentation of the patients and their management in otorhinolaryngology. Background NPC is a malignant disease with good prognosis on early diagnosis. However, the relationship between the dermatomyositis and NPC and its management is not well defined. Materials and methods A 10-year retrospective review of case records of 21 dermatomyositis patients seen in Otorhinolaryngology Department of Hospital Selayang from January 2000 to November 2010. Results These patients ranged from 19 to 74 years old and a total of 8 (38%) out of 21 adults with dermatomyositis were detected to have malignancy. Five out of 8 patients had NPC (62.5%). The mean age of patients with NPC and dermatomyositis was 48 years. NPC is diagnosed in 4 out of 5 patients (80%) in the first year of diagnosis of dermatomyositis. The clinical findings of the examination of nasopharynx ranged from hyperemia to exophytic nasopharyngeal mass. Histologically, it is only related to NPC of WHO types II and III. Conclusions There is a strong relationship between dermatomyositis and malignancy, especially NPC. Clinicians should have a high index of suspicion for malignancy in all dermatomyositis patients. Rigid nasoendoscopies and biopsies, serum Epstein–Barr viral capsid IgA antibody and imaging studies are helpful in detecting NPC in dermatomyositis patients. PMID:25184058

    The aim of the present study was to evaluate the incidence, epidemiological, clinical and therapeutic features of patients with pemphigus vulgaris in China. We retrospectively investigated a total of 221 patients with pemphigus vulgaris. The parameters including age at diagnosis/onset, sex, diagnostic methods, hospitalizations, side-effects with different treatments, pemphigus vulgaris-associated diseases, the therapeutic features and duration of follow up were evaluated. The male : female ratio was 1:1.40. The incidence rate was obviously higher in two age groups, 31-40 years and 41-50 years. The mean age at onset was 44.19 ± 21.45 years. The majority of patients (56.56%) presented the mucocutaneous type. In addition, we found that various doses of corticosteroids (including the mean initial dose, maximum control dose, total dose before reducing and hospitalized total dose) exhibited statistical differences between only corticosteroids and corticosteroids-immunosuppressant groups in mild, moderate and severe pemphigus vulgaris (P pemphigus vulgaris most frequently occurred in the 41-50-year age group in China and the majority of patients manifested mucocutaneous lesions. Importantly, the incidence rate in females was higher than in males. The patients who needed combined immunosuppressant treatment, usually needed higher doses of corticosteroids initially, to control the disease and over the total course of treatment.

    Academic self-efficacy and perceived teacher support in relation to academic skill growth across one academic year were examined in the study. Participants included 193 5th-grade students. Teachers collected curriculum-based measures (CBM) of reading and math on three occasions as part of routine academic benchmarks, and researchers collected student-reported measures of academic self-efficacy and perceived teacher support in the spring of the same academic year. Results indicated that academic self-efficacy was positively related to fall reading and math CBM scores and that perceived teacher support was unrelated to fall scores or growth across the academic year. Academic self-efficacy and perceived teacher support interacted in relation to math CBM growth such that low levels of perceived teacher support were related to greater growth, particularly for students with high academic self-efficacy. Follow-up analyses indicated that students with the lowest fall CBM scores and smallest growth rates reported higher levels of perceived teacher support, suggesting that teachers support the students most in need.

    2013-01-01

    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 students combined. North American students had a higher dropout rate than Irish and EU students; RR = 2.68 (1.09 to 6.58;p = 0.027) but this was not significant when transfers were excluded (RR = 1.32(0.38, 4.62);p = 0.75). Male students were more likely to dropout than females (RR 1.70, .93 to 3.11) but this was not significant (p = 0.079). 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

    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.

    Our objective was to determine tuberculosis (TB) incidence and evaluate TB risk in adults after one or more years of use of combination antiretroviral therapy (cART) through a retrospective cohort study in Jos, Nigeria. We studied a cohort of HIV-infected adults treated with ART for at least 1 year. Based on immunologic and virologic responses to ART, patients were categorized into four groups: CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level ≤400 copies/ml (group 1), CD4 T cell count ≥350 cells/mm(3) and HIV-1 RNA level >400 copies/ml (group 2), CD4 T cell count 400 copies/ml (group 4). Time to incident TB for the four groups was analyzed using the Kaplan-Meier method. Cox regression models were used to evaluate predictors of incident TB. In this cohort of 5,093 HIV-infected adults, of which 68.4% were female, with a mean age 35.1 years (standard deviation 9.1 years), we observed 98 cases of incident TB during 4 years and 3 months of follow-up. The overall TB incidence rate was 8.7 cases/1,000 patient-years of follow-up. Adjusted hazards for incident TB were 2.11 (95% CI 0.97-4.61), 2.05 (95% CI 1.10-3.79), and 3.65 (95% CI 1.15-5.06) in group 2, 3, and 4 patients, respectively, compared to group 1. Tuberculosis incidence in patients on ART is driven by poor immunologic and/or virologic response. Optimization of HIV treatment should be prioritized to reduce the burden of TB in this high-risk population.

    A retrospective review of 178 total temporomandibular joint replacements (TJR) performed on 106 patients at the University of Alabama at Birmingham during the years 2000-2010 was completed. Data regarding sex, past medical history, prosthesis manufacturer, microbiology, antibiotic therapy, and the need for additional procedures were obtained from the medical records of patients who developed a prosthetic joint infection following TJR. Of the 106 patients, 95 (89.6%) were female and 11 (10.4%) were male. The average age of the patients was 47 years (range 19-68 years). Sixty patients underwent bilateral TJR. The average length of follow-up was 41 months. Of the 178 TJR performed, eight joints (4.5%) developed an infection of the prosthesis, all requiring removal despite antibiotic therapy. The average time to onset of infection was 14.3 months (range 6 days to 72 months), while the average time to removal of the prosthesis was 26.9 months (range 10 weeks to 84 months). Microbiology data from the infected joints revealed colonization with coagulase-negative Staphylococcus (4/8 joints) and Propionibacterium (2/8 joints), as well as Serratia and Peptostreptococcus species. Three of the prostheses had negative cultures. Copyright © 2017 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

    Background Simultaneous pancreas-kidney transplantation (SPKT) is the best treatment option for diabetic patients with advanced chronic renal failure. The current study aimed to analyze the surgical indications, treatments and prognosis of SPKT.Methods We retrospectively analyzed 40 cases of SPKT performed between December 1999 and January 2010 in our center, including the survival rate, complications and the reasons of reoperation.Results Of all the 40 SPKT cases, the one-year survival rates of the recipients, kidney and pancreas transplant graft were 97.6%, 97.6% and 92.7%, while 97.6%, 91.1%, 92.7% at 3 years and 83.6%, 78.0%, 79.4% at 5 years, respectively.After SPKT, 10 patients need reoperation because of surgical complications (14 operations). The reoperation rate was 25%, including 2 patients (4 operations) with hematuria, 4 patients with abdominal hemorrhage, 2 patients (3 operations)with abdominal infection, 1 patient with pancreatic venous thrombosis, 1 patient with anastomotic leakage, and 1 patient with fistula.Conclusion Although SPKT provides a successful and effective treatment for diabetics with end-stage renal disease,how to reduce the complications of this treatment still need further effort.

    Many papers have been written in recent years discussing the interdisciplinary and transdisciplinary aspects of soil science. Therefore, it would make sense that soil science courses would be taken by students in a wide array of academic majors. To investigate this, we collected data from eight different American universities on the declared academic majors of students enrolled in soil science courses over a 10 year time period (2004-2005 to 2013-2014 academic years). Data was collected for seven different classes taught at the undergraduate level: introduction to soil science, soil fertility, soil management, pedology, soil biology/microbiology, soil chemistry, and soil physics. Overall trends and trends for each class were evaluated. Generally, environmental science and crop science/horticulture/agronomy students were enrolled in soil science courses in the greatest numbers. Environmental science and engineering students showed rapid increases in enrollment over the 10 years of the study, while the number of crop science/ horticulture/ agronomy students declined. In the introduction to soil science classes, environmental science and crop science/ horticulture/ agronomy students were enrolled in the greatest numbers, while declared soil science majors only made up 6.6% of the average enrollment. The highest enrollments in soil fertility were crop science/ horticulture/ agronomy students and other agricultural students (all agricultural majors except crop science, horticulture, agronomy, or soil science). In both the soil management and pedology classes, environmental science and other agricultural students were the largest groups enrolled. Other agricultural students and students from other majors (all majors not otherwise expressly investigated) were the largest enrolled groups in soil biology/microbiology courses, and environmental science and soil science students were the largest enrolled groups in soil chemistry classes. Soil physics was the only class

    This three-phase prospective study investigated psychosocial factors predicting or associated with academic achievement. An initial sample of 1,514 school-age children was assessed with screening tools for emotional problems (Screen for Childhood Anxiety and Related Emotional Disorders; Leyton Obsessional Inventory-Child Version; Children's Depression Inventory). The following year, 562 subjects (risk group/without risk group) were re-assessed and attention deficit/hyperactivity disorder (ADHD) was assessed. Two years later, 242 subjects were followed, and their parents informed about their academic achievement. Results showed that early depression (phase 1 B = -.130, p = .001; phase 1 + phase 2 B = -.187, p academic achievement (phase 1 + phase 2 B = -3.415, p = .005). However, some anxiety symptoms can improve academic achievement (Social phobia B = .216, p = .018; Generalized anxiety B = .313, p academic achievement. We can conclude that in the transition period to adolescence, school-health professionals and teachers need to consider the emotional issues of students to avoid unwanted academic outcomes.

    Adherence to anti-osteoporosis medications is poor. We carried out a cohort study using a real-world population database to estimate the persistence of anti-osteoporosis drugs. Unadjusted 2-year persistence ranged from 10.3 to 45.4%. Denosumab users had a 40% lower risk of discontinuation at 2 years compared to alendronate users. The purpose of this study was to estimate real-world persistence amongst incident users of anti-osteoporosis medications. This is a retrospective cohort using data from anonymised records and dispensation data ( www.sidiap.org ). Eligibility comprised the following: women aged ≥50, incident users of anti-osteoporosis medication (2012), with data available for at least 12 months prior to therapy initiation. Exclusions are other bone diseases/treatments and uncommon anti-osteoporosis drugs (N year persistence with a permissible gap of up to 90 days. Persistence with alendronate was compared to other bisphosphonates, strontium ranelate, selective oestrogen receptor modulators, teriparatide and denosumab. Cox models were used to estimate hazard ratios of therapy cessation according to drug used after adjustment for age, sex, BMI, smoking, alcohol drinking, Charlson co-morbidity index, previous fractures, use of anti-osteoporosis medication/s, oral corticosteroids and socio-economic status. A total of 19,253 women were included. Unadjusted 2-year persistence [95% CI] ranged from 10.3% [9.1-11.6%] (strontium ranelate) to 45.4% [43.1-47.8%] (denosumab). One-year persistence went from 35.8% [33.9%-37.7%] (strontium ranelate) to 65.8% [63.6%-68.0%] (denosumab). At the end of the first year and compared to alendronate users, both teriparatide and denosumab users had reduced cessation risk (adjusted HR 0.76, 95% CI 0.67-0.86 and 0.54, 95% CI 0.50-0.59 respectively) while at the end of the second year, only denosumab had a lower risk of discontinuation (adjusted HR 0.60, 95% CI 0.56-0.64). Unadjusted 2-year persistence is suboptimal. However

    2010-08-01

    The primary purpose of this longitudinal study was to examine, in a sample of Chinese children (initial M age = 8 years, N = 1,140), contributions of aggression to the development of social competence and academic achievement. Five waves of panel data on aggression and social and school performance were collected from peer evaluations, teacher ratings, and school records in Grades 2 to 5. Structural equation modeling revealed that aggression had unique effects on later social competence and academic achievement after their stabilities were controlled, particularly in the junior grades. Aggression also had significant indirect effects on social and academic outcomes through multiple pathways. Social competence and academic achievement contributed to the development of each other, but not aggression. The results indicate cascade effects of aggression in Chinese children from a developmental perspective.

    The main aim of this study was to analyze the relationship between the amount of physical activity and academic performance in 3rd-year secondary education students. The sample was taken from three secondary schools in the area of Barcelona. 284 students (158 girls, 126 boys) with an average age of 14.7 yr. participated. The International Physical Activity Questionnaire was used by students to self-report their amount of physical activity. Students' academic records were obtained for comparisons. Results showed that there was a linear relationship between academic performance and physical activity; nevertheless, there was a trend to stronger correlation when modeling the relationship between these variables with a quadratic equation. Further research should focus on whether academic performance and physical activity might be better explained with a second-order equation.

    Some patients do not take medicines as they are supposed to. Our research showed that in Estonia, one fifth of patients did not start treatment with osteoporosis medicines and only 20% used the medicines for at least 3 years as they should. This induces unnecessary costs to the healthcare system. Medication non-adherence is the number one reason for not obtaining the expected clinical effect of medicines. With osteoporosis treatment, it has been shown that both implementation of treatment and persistence influence the risk of fractures significantly. Long-term adherence to medication in Estonia is to be determined with this study. A 15-year retrospective study was carried out in order to establish initiation, implementation, and persistence of Estonian patients. All new users of osteoporosis medicines were analyzed for all prescriptions they received during the study period. Sufficient adherence to treatment was defined as a patient being dispensed 80% or more prescribed doses for at least 1 year. The study period was from 2001 to 2015. Patients (24,652) were included in the study. Of the patients, 93.7% (n = 23,091) were women and 6.3% (n = 1564) were men. Eighteen percent (4636) were dispensed only one prescription. Of the patients, 44.2% included in the study had medication possession ratio (MPR) ≥80% over follow-up period; 8922 (36.2%) who were prescribed from 2001 to 2015 persisted for 1 year with MPR ≥80% and 19.8% persisted for 3 years. Forty percent of expenditure on osteoporosis medication was made for treatment courses with insufficient adherence. There is room for improvement in Estonia with medication adherence relating to all three aspects that determine adherence-initiation, implementation, and persistence. This means further efforts are to be made to educate patients and healthcare professionals on realizing the importance of good adherence.

    Little is known about the incidence of nephrolithiasis in the United States Navy. Navy pilots must be kidney stone-free and are often referred for treatment of small asymptomatic stones. The primary objectives of this study were to determine the incidence of nephrolithiasis and computerized tomography, proportion undergoing treatment and incidence of stone related mishaps in Navy pilots compared with other Navy personnel. We retrospectively studied the records of all Navy service members from 2002 to 2011 for nephrolithiasis based on ICD-9 stone codes to determine the mentioned rates. We also reviewed NSC (Naval Safety Center) data for a history of accidents associated with nephrolithiasis. Rates of disease were calculated using person-years of followup and inferential statistics were done using univariable and multivariable analyses. We evaluated 667,840 Navy personnel with a total of 3,238,331 person-years of followup. The annual incidence of nephrolithiasis was 240/100,000 person-years with a 5-year recurrence rate of 35.3%. On multivariable analysis pilots had nephrolithiasis incidence and treatment rates similar to those of the overall Navy population. Women had a higher incidence of nephrolithiasis compared with men (OR 1.17, p <0.0001). The rate of computerized tomography was lower in pilots than in the rest of the Navy (39 vs 66/10,000 person-years, p <0.0001). No recorded accidents were associated with kidney stones. Navy pilots had a similar incidence of nephrolithiasis and were no more likely to undergo a surgical procedure. Given that no accidents were associated with nephrolithiasis, this study suggests reconsidering current military policies necessitating pilots to be completely stone-free.

    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.

    The Collaboratory for the Study of Earthquake Predictability was developed to prospectively test earthquake forecasts through reproducible and transparent experiments within a controlled environment. From January 2006 to December 2010, the Regional Earthquake Likelihood Models (RELM) Working Group developed and evaluated thirteen time-invariant prospective earthquake mainshock forecasts. The number, spatial and magnitude components of the forecasts were compared to the observed seismicity distribution using a set of likelihood-based consistency tests. In this RELM experiment update, we assess the long-term forecasting potential of the RELM forecasts. Additionally, we evaluate RELM forecast performance against the Uniform California Earthquake Rupture Forecast (UCERF2) and the National Seismic Hazard Mapping Project (NSHMP) forecasts, which are used for seismic hazard analysis for California. To test each forecast's long-term stability, we also evaluate each forecast from January 2006 to December 2015, which contains both five-year testing periods, and the 40-year period from January 1967 to December 2006. Multiple RELM forecasts, which passed the N-test during the retrospective (January 2006 to December 2010) period, overestimate the number of events from January 2011 to December 2015, although their forecasted spatial distributions are consistent with observed earthquakes. Both the UCERF2 and NSHMP forecasts pass all consistency tests for the two five-year periods; however, they tend to underestimate the number of observed earthquakes over the 40-year testing period. The smoothed seismicity model Helmstetter-et-al.Mainshock outperforms both United States Geological Survey (USGS) models during the second five-year experiment, and contains higher forecasted seismicity rates than the USGS models at multiple observed earthquake locations.

    This review describes a collaborative educational practice model partnering midwifery and obstetrics within a department of obstetrics and gynecology. For more than 20 years, the authors' model has demonstrated sustainability and influence on medical education. The focus is on resident education in obstetrics, using midwifery faculty as teachers in the obstetric and obstetric triage settings. This noncompetitive and integrated educational practice model has achieved sustainability and success using midwives in a collaborative approach to medical education. The continuing collaboration and innovation within medical and resident education are important elements for the future of collaborative practice.

    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.

    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.

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

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

    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.

    The evolution of the Internet is increasing at an ever-increasing rate. The rate of incorporation of Internet-based resources into university courses, however, does not seem to be keeping pace. In large part this seems to be a function of the mindset of university faculty rather than a technological shortcoming. For the past few years faculty have used the Internet to learn how their colleagues are adopting this new medium into their courses. Password-protected course pages will restrict that learning process if university administration and publishers exercise ownership of the intellectual property produced by faculty. A team approach is needed with instructors providing the content and graphic designers, programmers, and cognitive experts adding their skills to produce the final product. This team should be involved from conception through assessment of the results. Focusing on the development of an entire course may not be a wise investment of time and money for a faculty member. It may make more sense to focus on the development of small segments, units or modules or analytical tools that can be incorporated into a variety of courses at other institutions. If such units can be evaluated as good practices, and if an efficient distribution mechanism can be devised, the benefits should increase exponentially as new resources are contributed.

    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.

    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 The burns intensive care unit (BICU staff observed an increasing number of pediatric scald burn admissions as a result of increase injuries associated with the scald burns. A retrospective study was conducted to identify scalds demographics, etiologies, and mortality risk factors. This descriptive study comprised a total of 166 patients aged 0-5 years, who were admitted to the BICU of the Reconstructive Plastic Surgery and Burns Unit (RPSBU through the Accident and Emergency (A and E Centre of the Komfo Anokye Teaching Hospital (KATH from May 1 st 2009 to April 30 th 2012. Source of information was the BICU Computerized Database System. Data extracted included demographics as well as treatment methods and outcomes. The study population was 166; 92 (55.4% males and 74 (44.6% females. Scalds admissions were 141 (84.9%; 13 (9.2% of them died, 83 (58.9% discharged, and 45 (31.9% transferred-out to another burn ward and pediatric surgery ward in the hospital. Scald patients' demographics included 78 males (55.3% and 63 females (44.7%; mean age was 2.18 years. Mortality risk factors identified were age <3 years (P = 0.044; scalds from hot water (P = 0.033, total burns surface area >30% (P = 0.017, and multiple body parts affected (P = 0.049. The current study showed age, hot water, and Total Burns Surface Area (TBSA as risk factors of early childhood scalds. Education on scalds prevention targeting mothers/caregivers is needed to create awareness of the frequency, severity, and danger associated with pediatric scalds.

    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.

    2011-03-01

    Studies have indicated that academic research has become increasingly complex and multidisciplinary. There seems to be an increasing trend of multiple author articles published across most journals. As the field of biomedical engineering also encompasses multidisciplinary-based knowledge, it is interesting to understand the authorship trend over time. In this study, six journals were carefully chosen from the Journal Citation Report of the Thomson Scientific based on predefined criteria (year 1999 to 2008). The data pertaining to authorships for the articles published in these journals were then acquired from the PubMed database. The results show that there is a general upward trend for the number of author per article, but it is not significant (p > .01) despite a 64.5% increase in the total number of article published in the six chosen journals. Thus, the expected increase is not observed in this field, and it may be due to the stringent guidelines by journals in defining the contributions of an author. Particularly, contributing factors like the impact of authorship irregularities is discussed herein.

    The National Aeronautics and Space Administration (NASA) phased down its Apollo Moon Program after 1970 in favor of a partly reusable Space Shuttle vehicle that could be used to construct and supply a manned, Earth-orbiting Space Station. Applications programs were emphasized in response to the growing public concern about Earth's finite natural resources and the degradation of its environment. Shortly thereafter, a workshop was convened in Norfolk, Virginia, on Remote Measurement of Pollution (or RMOP), and its findings are in a NASA Special Publication (NASA SP-285). The three primary workshop panels and their chairmen were focused on trace gas species (Will Kellogg), atmospheric particulates or aerosols (Verner Suomi), and water pollution (Gifford Ewing). Many of the workshop participants were specialists in the techniques that might be employed for the regional to global-scale, remote measurements from an Earth-orbiting satellite. The findings and recommendations of the RMOP Report represent the genesis of and a blueprint for the satellite, atmospheric sensing programs within NASA for nearly two decades. This paper is a brief, 40-year retrospective of those instrument developments that were an outgrowth of the RMOP activity. Its focus is on satellite measurement capabilities for temperature and gaseous species that were demonstrated by atmospheric technologists at the Langley Research Center. Limb absorption by solar occultation, limb infrared radiometry, and gas filter correlation radiometry techniques provided significant science data, so they are emphasized in this review.

    Full Text Available Hanging is violent asphyxial death. The objective of this study is to assess the data of hanging cases. A descriptive-retrospective study was conducted. We studied 244 hanging cases autopsied in Forensic Division, Department of Pathology, Faculty of Medicine Ramathibodi Hospital, Mahidol University, Bangkok, Thailand, between January 2001 and December 2013. The study included 197 men (80.7% and 47 women (19.2%. Their age ranged from 14 to 93 years. Most of these cases were incomplete hanging (83.6%. Features of hanging victims, such as tongue protrusion; congestion of face; petechial hemorrhage of face, conjunctiva, and internal organs; and neck injuries, significantly correlated with complete hanging. The predominant occupation of hanging victims was in the service industry (63.1%. Suicides usually occurred in private homes or apartments (84.8%. A suicide note was found in 6.1% of cases. The most common ligature material used was nylon rope, found in 61.1% of cases. The most underlying diseases of the victims in hanging cases were tuberculosis and human immunodeficiency virus infection, 9 cases each. Blood ethanol levels of 29 cases (11.8% were detected to be higher than 150 mg%. Methamphetamine and benzodiazepine were detected in 5.3% and 3.3% of cases, respectively. This study provides comprehensive baseline data of hanging cases in central Bangkok.

    A fungal ball consists of a dense conglomerate of fungal hyphae growing at the surface of the sinus mucosa without tissue infiltration. The maxillary sinus is by far the most commonly involved paranasal sinus cavity followed by the sphenoid sinus. The present study is a retrospective study of 25 consecutive cases treated during the last 10 years in the two hospitals be- longing to the Catholic University of Louvain (CHU Mont-Godinne and UCL Saint Luc). We report the symptomatology, the imaging and discuss the different surgical managements. We conclude that the clinician must have a high index of suspicion when dealing with a unilateral rhinosinusitis persisting despite a maximal and well conducted medical treatment. This is particularly so in elderly women when associated with facial pain and post nasal drip, particularly when the computed tomography shows an unilateral opacity of the sphenoid sinus with or without a sclerosis or an erosion of the bony walls, a polyp in the sphenoethmoidal recess or a hyperdensity mimicking a foreign body. An endonasal endoscopic sphenoidotomy is the treatment of choice in most cases, allowing good ventilation of the sinus and radical removal of all the fungal concretion. A biopsy of the sinus mucosa adjacent to fungal elements is of upmost important to confirm the non- invasiveness of the fungi within the tissue. Antifungal medication is not required in uncomplicated forms. All host factors producing some degree of immunosuppression must be corrected when present and must alert the clinician to rule out any forms of invasive disease.

    Objective This study aims to analyze the clinical and endoscopic presentations of upper gastrointestinal bleeding (UGIB) in the Chinese children. Methods A 10-year retrospective study was made on children with UGIB and undertaken esophagogastroduodenoscopy (EGD) from 4 tertiary referral centers in China. Results Of the 1218 children studied, the bleeding source was found in 76.4%. Erosive gastritis was the most common endoscopic finding (33.5%), followed by duodenal ulcer (23.2%). The proportion of erosive gastritis decreased with age (correlation coefficient = -0.787), and duodenal ulcer increased with age (correlation coefficient = 0.958). The bleeding source was more likely to be determined in children having EGDs within 48 hours (80.6% vs 67.9%). Conclusions In Chinese children with UGIB, erosive gastritis and duodenal ulcer were the leading causes, and their proportions varied with age. EGDs performed within 48 hours may improve the possibility of finding the source of bleeding. © The Author(s) 2015.

    Young people attending genitourinary medicine services are at high risk of unplanned pregnancy. We performed a retrospective cohort study to identify characteristics of pregnant teenagers accessing an inner London genitourinary medicine service. There were 481 pregnancies in 458 teenagers with 54 previous pregnancies and 46 previous terminations of pregnancy. The under-18 and under-16 teenage pregnancy rates were 92.1 and 85.8 per 1000 age-matched clinic attendees, respectively. Median age was 17.1 years. 'Black Other' teenagers ('Black British', 'Mixed White-Black Caribbean' and 'Mixed White-Black African') were over-represented, compared to our clinic population, while those of White ethnicity were under-represented. Few pregnancies (1.5%) were planned with the majority (64%) intending terminations of pregnancy. Most teenagers did not use consistent contraception. Two-thirds of patients had attended genitourinary medicine services in the past and sexually transmitted infection prevalence at presentation was high. Effectively targeting the sexual and reproductive health needs of teenage genitourinary medicine clinic attendees may have a significant impact on reducing sexually transmitted infections, unplanned pregnancy and terminations of pregnancy in this group. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    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.

    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%.

    Dengue fever is a frequent cause of morbidity in travellers. The objective was to describe the epidemiological and clinical characteristics of dengue fever in Czech travellers. This descriptive study includes patients with acute dengue fever diagnosed at Hospital Na Bulovce during 2004-2013. Data were collected and analysed retrospectively. A total of 132 patients (83 males and 49 females) of median age 33 years (IQR 29-40) were included. Diagnosis was established by NS1 antigen detection in 87/107 cases (81.3%) and/or RT-PCR in 50/72 (69.4%) and by serology in 25 cases (18.9%). Dengue was acquired in South-East Asia in 69 cases (52.3%), followed by South Asia (48 cases; 36.3%), Latin America (14; 10.6%) and Sub-Saharan Africa (1; 0.8%). The most frequent symptoms included fever, rash and headache. Initial leukocyte and lymphocyte counts were lower in patients who presented in the early phase (0-4 days), however, platelet count was lower and AST, ALT and LDH activity higher in patients with a longer symptoms duration (≥5 days). The clinical course was mostly uncomplicated. Dengue fever is becoming a frequent cause of fever in Czech travellers. Clinicians should be familiar with the typical clinical findings and novel diagnostic methods. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A three-year retrospective analysis of fungi isolated from specimens of patients with superficial fungal infections in French Guiana is presented. Clinical samples from 726 patients with presumptive diagnoses of onychomycosis (28.2% of the patients), tinea capitis (27.8%), superficial cutaneous mycoses of the feet (22.0%), and of other areas of the body (21.9%), were assessed by microscopic examination and culture. Dermatophytes accounted for 59.2% of the isolates, followed by yeasts (27.5%) and non-dermatophytic molds (13.1%). Trichophyton rubrum was the most common dermatophyte recovered from cases of onychomycosis (67.4%), tinea pedis (70.6%) and tinea corporis (52.4%). In contrast, Trichophyton tonsurans was the predominant species associated with tinea capitis (73.9%). Yeasts were identified as the principal etiologic agents of onychomycosis of the fingernails (74.2%), whereas molds were found mainly in cases of onychomycosis of the toenails. In such instances, Neoscytalidium dimidiatum (70.8%) was the most common mold recovered in culture. In conclusion, the prevalence of T. rubrum and the occurrence of onychomycosis and fungal infections of the feet in French Guiana are similar to results reported from Europe, whereas the frequency of tinea capitis and the importance of T. tonsurans in such infections are similar to the situation in the Americas.

    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.

    Male breast cancer (MBC) is rare. Molecular subtype has been utilized widely in female breast cancer. But the relationship between subtype and prognosis in MBC patients is still unknown. We aim to study the impact of molecular subtype on the prognosis of MBC. We identified MBC cases from 1990 to 2011 retrospectively; molecular subtype was assigned by immunohistochemistry. We compared overall survival in different subtypes by Kaplan-Meier method and COX proportional hazard regression model. 68 patients with MBC were included in analysis with 115 months of a median follow-up time. Comparing to non-luminal A (subtypes of Luminal B, HER2 over-express and Basal-like) group, patients with luminal A had a lower recurrent rate and better overall survival (10-year survival rate was 78.0% vs 67.0%, mean survival time 197.46 ± 12.22 months vs 146.51 ± 16.88 months, p < 0.05). Molecular subtype may have prognosis-predicting value for MBC. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The objective of this study was to determine whether professional maintenance appointments were related to a decrease on dental implant loss. We performed a retrospective review (1995-2012) of 1020 patient dental charts to collect data including a cadre of different variables such as age, gender, race, diabetes, osteoporosis, jaw location, implant dimensions and professional maintenance therapy. As a patient may have multiple implants which are correlated, we selected one random implant per patient to assure independence of observations assumption of the Cox proportional hazards regression model. Data analysis was performed using Kaplan-Meier survival curves and multivariate analysis using Cox proportional hazards regression analysis. Our results demonstrate that subjects with no maintenance had the lowest cumulative survival rate as compared to subjects with regular maintenance. In a multivariate Cox regression model, regular maintenance patients had the dental implant failure rate reduced by 90% as compared to no maintenance (P = 0.001). If patients had less than one maintenance visit per year, the failure rate was reduced by 60% as compared to no maintenance, but the difference was not statistically significant (P = 0.08). From this research, we conclude that a professional administered periodontal maintenance at least on an annual basis is a critical factor for implant survival. © 2015 The Authors.

    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.

    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.

    Delirium is characterized by disturbances of attention and cognition that cause functional decline and complications. The predisposing factors of delirium are age, male gender, systemic or metabolic disorders, dementia, and stroke. This study aims to evaluate the prevalence of delirium and to identify risk factors. This is a retrospective study that includes patients admitted over 5 years with acute stroke. Patients with transient ischemic attack or venous thrombosis were excluded. Delirium was defined according the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Demographical characteristics, clinical-radiological profile, dependence on discharge (modified Rankin Scale score of ≥3 and Barthel Index delirium. A total of 1161 patients were admitted (910 ischemic and 162 hemorrhagic). During hospitalization, 118 patients presented with delirium (10.2%) and 93 died (8%). On discharge, 517 patients were dependent (44.5%). Delirium was significantly associated with age, male gender, cortical infarcts in anterior circulation, higher leukocyte count, cholesterol and fibrinogen levels, lower albumin, atrial fibrillation, previous diagnosis of Alzheimer's disease, and hemorrhagic stroke. Logistic regression results showed that only previous Alzheimer's disease was related to delirium (odds ratio 21.68 [95% confidence interval 1.190-395.026, P = .038]). Dependence on discharge was associated with delirium. Ten percent of the patients presented with delirium associated with older age, Alzheimer's disease, and cortical anterior stroke. Patients with delirium had a higher risk of functional dependence on discharge. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available Aim. To estimate number of children being diagnosed with chronic fatigue syndrome (CFS. Methods. For a period of 10 years (2002–2011 data from children being referred for fatigue symptoms were collected retrospectively. Results. Thirty-seven children were referred. Four were excluded due to incorrect coding. Six (18% patients received other diagnoses at the end of evaluation time. Of the 27 who received the diagnosis G93.3, four had a previous chronic illness, while 23 patients were previously healthy. All patients reported onset of fatigue symptom in relation to an infection, and all tested positive for IgG to either Epstein-Barr virus, cytomegalovirus or borrelia, indicating previous infection. There were 16 (59% boys among the 27 patients. The mean age at the debut of fatigue symptoms was 141 months (SD 30 for boys and 136 months (SD 31 for girls, respectively. Being underweight, defined as BMI < 17.5, was found in 12 (44% patients. Conclusion. An increasing number of children and adolescents are evaluated for CFS. The clinical assessment of children and adolescents with possible CFS need systematically evaluation. Nutritional status, possible eating disorder, and psychosocial issues need to be addressed and evaluated carefully. A multidisciplinary approach is essential when assessing CFS in children and adolescents. There is a need for European guidelines.

    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

    Full Text Available This retrospective analytical study aimed at making a database of patients who underwent renal transplant from 31 December 2004 to 31 December 2006 under the Faculty of Medicine renal transplant program. The objective was to build a profile of renal transplant patients with focus on post KT infections and complications of renal transplants. An interviewer administered questionnaire was used. A total of 72 patients were studied; 18 (25% had died by February 2007. Forty-three patients (58.3% were interviewed in person, 17 were interviewed over the phone and 12 patients could not be contacted. Of those who were interviewed, 28 (38.9% were on azathioprine, prednisolone and cyclosporine, while 15 (20.8% were on predni-solone, cyclosporin and mycophenolate mofetil. Four patients had symptomatic cytomegalovirus infection and five had tuberculosis post transplant. Of all infections, the most commonly reported was urinary tract infection (11 cases. Thirty-three (45.8 % had received induction therapy with either basiliximab (n = 8 or daclizumab (n = 25. Acute rejection was the most commonly en-countered complication, with nine cases (12.5% being reported over the study period. Of late complications, most were due to immunosuppression. Overall, the 2-year survival was 75%. There was no significant difference between the centers of transplant.

    Full Text Available The baseline prevalence and characteristics of tuberculosis (TB among general healthcare workers (HCWs in southeastern China remains unknown. We conducted a retrospective study based on the TB surveillance data in Zhejiang Province from 2005 to 2011, which were extracted from the national Tuberculosis Information Management System (TIMS. We calculated and compared annual notification rates of different occupational groups and analyzed the epidemiological and clinical characteristics. The annual TB notification rates among general HCWs declined steadily from 2005 to 2011. On average, HCWs showed annual TB notification rates lower than the general population but higher than teachers. Recorded HCW TB patients averaged 35.5 years of age, with females outnumbering males (58.0% > 42.0%. The proportion of pulmonary tuberculosis (PTB was higher among male than in the female patients (88.5% > 83.4%, P = 0.031. Our study suggested that general HCWs run a higher occupational risk than teachers although the two groups are socioeconomically comparable and that the priority should be given to the young female HCWs for TB prevention in healthcare institutions.

    Full Text Available 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.

    Background: The laryngeal mask airway (LMA) is the most commonly used rescue airway in obstetric anesthesia. The aim of this retrospective cohort study was to evaluate the application of the LMA in parturients undergoing cesarean delivery (CD) for 5 years in our hospital. As a secondary objective, we investigated the incidence of airway-related complication in obstetric general anesthesia (GA). Methods: We collected electronic data for all obstetric patients who received GA for CD between January 2010 and December 2014 in Peking University First Hospital. Based on the different types of airway device, patients were divided into endotracheal intubation (ET) group and LMA group. The incidences of regurgitation and aspiration, as well as maternal and neonatal postoperative outcomes were compared between groups. Results: During the 5-year study, GA was performed in 192 cases, which accounted for 2.0% of all CDs. The main indications for GA were contraindication to neuraxial anesthesia or a failed block. Among these, ET tube was used in 124 cases (68.9%) and LMA in 56 cases (31.1%). The percentage of critical patients above the American Society of Anesthesiologists' Grade II was 24/124 in ET group and 4/56 in LMA group (P = 0.036). The emergent delivery rate was 63.7% for ET group and 37.5% for LMA group (P = 0.001). None of the patients had regurgitation or aspiration. There were no significant differences in terms of neonatal Apgar scores, maternal and neonatal postoperative outcomes between the two groups. Conclusions: Our results suggested that GA was mainly used for contraindication to neuraxial anesthesia or a failed block, and emergent CDs accounted for most cases. The second-generation LMA could be used for obstetric anesthesia, but correct position to achieve a good seal is the key to prevent reflux and aspiration. Whether they could replace the tracheal tube in routine practice needs further large prospective studies. PMID:28218212

    Typhoid is a leading cause of fever in returning travelers. The prevalence is highest in migrants visiting friends and relatives (VFR travelers) in the Indian subcontinent, where reports of resistance have been of concern. This study is a retrospective analysis of patients with typhoid, seen over a 5-year period, in a tertiary center that serves a large immigrant population. Patients with blood cultures positive for Salmonella Typhi were identified between 2006 and 2010. Charts were reviewed for demographic data, travel history, symptoms and signs, basic laboratory results, susceptibility profiles, treatment, and clinical course. Resistance to nalidixic acid was used as a marker of decreased susceptibility to quinolones. Seventeen patients were identified with S Typhi. The median age was 12 years (range: 2-47 y) and 94% (16 of 17) were hospitalized with a median stay of 7 days; two were admitted to the intensive care unit. Fourteen patients (82%) had a history of recent travel. Twelve were VFR travelers in Bangladesh and Pakistan and two had recently immigrated. In our study, typhoid patients had low eosinophil counts and elevated transaminases. Seventy-six percent (12 of 17) of all isolates were resistant to nalidixic acid, 23.5% (4 of 17) were resistant to ampicillin and co-trimoxazole, and one was resistant to ciprofloxacin. All isolates were susceptible to third-generation cephalosporins. Younger VFR travelers appear to be at greater risk of acquiring infection and developing complications. Absolute eosinopenia and increased liver function test values could be useful early diagnostic clues in a returning traveler with fever, once malaria has been excluded. There was a high rate of decreased susceptibility to fluoroquinolones, confirming that the use of third-generation cephalosporins or macrolides in patients from the Indian subcontinent is most appropriate. Prevention in VFR travelers to South Asia is critical and efforts should be targeted at better education

    Traumatic dental injuries present complex injuries of the dentoalveolar system. Aim of this study was to investigate the frequency and patterns of traumatic dental injuries in a University dental emergency service over four years. A retrospective investigation on all dental trauma patients presenting at the dental emergency service of the University Medical Center Mainz, Germany between 01/2010 and 12/2013 was conducted. Demographic data, the cause and type of trauma and the initial therapy were analyzed. Out of 16,301 patients, 1,305 patients (8 %; average age 14.7 years ±15.7; 60.1 % male, 39.9 % female) came due to trauma. 63.9 % of the traumas occurred on weekends. The most frequent reason for injuries was falls (54.6 %). No correlation could be found between the cause and the kind of trauma. In 48.6 % of the cases only one tooth was involved, in 33.5 % two. The permanent dentition was traumatized in 56.6 % of cases, the deciduous teeth in 41.1 %. The most frequently affected tooth was the central upper incisor (61.0 %). Hard-tissue injuries were significantly more frequent in the permanent dentition, while periodontal injuries were seen significantly more often in the deciduous dentition. Eight percent of all patients seeking help at the dental emergency service presented with trauma, meaning that dental traumatology is one of the major topics in emergencies. To improve the quality of care, further public education, expert knowledge among dental professionals and a well-structured emergency service are necessary.

    Full Text Available Background: Healthcare-associated pneumonia (HCAP is associated with drug-resistant pathogens and high mortality, and there is no clear evidence that this is due to inappropriate antibiotic therapy. This study was to elucidate the clinical features, pathogens, therapy, and outcomes of HCAP, and to clarify the risk factors for drug-resistant pathogens and prognosis. Methods: Retrospective observational study among hospitalized patients with HCAP over 10 years. The primary outcome was 30-day all-cause hospital mortality after admission. Demographics (age, gender, clinical features, and comorbidities, dates of admission, discharge and/or death, hospitalization costs, microbiological results, chest imaging studies, and CURB-65 were analyzed. Antibiotics, admission to Intensive Care Unit (ICU, mechanical ventilation, and pneumonia prognosis were recorded. Patients were dichotomized based on CURB-65 (low- vs. high-risk. Results: Among 612 patients (mean age of 70.7 years, 88.4% had at least one comorbidity. Commonly detected pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Initial monotherapy with β-lactam antibiotics was the most common initial therapy (50%. Mean age, length of stay, hospitalization expenses, ICU admission, mechanical ventilation use, malignancies, and detection rate for P. aeruginosa, and Staphylococcus aureus were higher in the high-risk group compared with the low-risk group. CURB-65 ≥3, malignancies, and mechanical ventilation were associated with an increased mortality. Logistic regression analysis showed that cerebrovascular diseases and being bedridden were independent risk factors for HCAP. Conclusion: Initial treatment of HCAP with broad-spectrum antibiotics could be an appropriate approach. CURB-65 ≥3, malignancies, and mechanical ventilation may result in an increased mortality.

    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.

    Although reassuring data on suicide risk in UK veterans of the 1982 Falklands conflict and 1991 Gulf conflict have been published, there have been few studies on long-term overall suicide risk in UK veterans. To examine the risk of suicide in a broad population-based cohort of veterans in Scotland, irrespect ive of length of service or exposure to conflict, in comparison with people having no record of military service. A retrospective 30-year cohort study of 56205 veterans born 1945-85 and 172741 matched non-veterans, using Cox proportional hazard models to compare the risk of suicide and fatal self-harm overall, by sex, birth cohort, length of service and year of recruitment. There were 267 (0.48%) suicides in the veterans compared with 918 (0.53%) in non-veterans. The difference was not statistically significant overall [adjusted hazard ratio (HR) 0.99; 95% confidence interval (CI) 0.86-1.13]. The incidence was lower in younger veterans and higher in veterans aged over 40. Early service leavers were at non-significantly increased risk (adjusted HR 1.13; 95% CI 0.91-1.40) but only in the older age groups. Women veterans had a significantly higher risk of suicide than non-veteran women (adjusted HR 2.44; 95% CI 1.32-4.51, P < 0.01) and comparable risk to veteran men. Methods of suicide did not differ significantly between veterans and non-veterans, for either sex. The Scottish Veterans Health Study adds to the emerging body of evidence that there is no overall difference in long-term risk of suicide between veterans and non-veterans in the UK. However, female veterans merit further study.

    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.

    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.

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available Evidence shows that work stress increases risk of cardiovascular disease. Emotional, cardiovascular and endocrine responses are affected by day-to-day experience. Perceived stress, negative mood, heart rate (HR and blood pressure (BP increase in working periods. Cortisol (C response is not so clear, there being contradictory results. The main purpose is to study stress markers in two working days in teachers. Moreover, we evaluate the role of gender in stress markers in 49 school teachers. Perceived stress, mood, BP, HR, and C were measured at the beginning and at the end of an academic year. Results show that psychological and heart rate responses to a working day were different at the end of the year, increasing, especially in men. BP and C responses descended at the end of the year. In conclusion, an academic year could affect negatively to the emotional state and heart rate of teachers.

  1. Does academic performance in the premedical year predict the performance of the medical student in subsequent years?

    2008-05-01

    Student admission into the College of Medicine at King Saud University (KSU) is dependent on the achievement of a grade point average (GPA) of ≥3.5 /5 by the end of the premedical year. This study was undertaken to ascertain whether pre-selected medical students who achieve a relatively low GPA (≤3.75/5) in the premedical year are at risk of having academic difficulties in subsequent years. A cross-sectional study of all students admitted to the College of Medicine at KSU during 5 academic years (1994 to 1998) was conducted in 2004. The likelihood of completing the program by 2004 and the dropout frequency were compared in the two groups based on their GPA in the premedical year: High GPA (>3.75) and Low GPA (≤3.75). During the study period, 739 students were admitted to the college. Of these, 619 (84%) were in High GPA group, and 120 (16%) in the Low GPA group. Of the students with High GPA, 545 (88%) out of 619 graduated compared with 79 (66%) of 120 in the Low GPA group (OR 3.822 [95% CI: 2.44, 5.99]: PGPA group (10/120; 8.3%) compared with the High GPA group (18/619; 2.9%: OR 3.035 [95% CI: 1.37, 6.75], P=0.01). Our results support the prerequisite of a minimum GPA in the premedical year before proceeding to the higher levels. The GPA of premedical year is a useful predictor of students who need close monitoring and academic support. The use of GPA in the premedical year for admission into medical colleges should help optimize the use of resources and reduce student wastage.

    Full Text Available Background: The biological behavior of endometrial carcinoma differs in epidemiology, presentation, and prognosis, suggesting that there are two fundamentally different pathogenic types of disease: type I (estrogen related, endometrioid type and type II (non-estrogen related, non-endometrioid type. Untreated hyperplasia can develop into an endometrioid type of adenocarcinoma, hence, it is important to recognize the former type. In contrast to cervical cancers, there are limited studies with respect to the biology of hyperplastic lesions documented from India. This was a 16-year retrospective study, carried out to determine the nature and outcome of proliferative lesions of the endometrium in a referral center from south India. Materials and Methods: A histopathological diagnosis of the endometrial hyperplasia, polyp, and carcinoma, on endometrial biopsy and hysterectomy specimens, over a 16 year period (1983 to 1999, were recorded in a computer and the case slides were reviewed. Using the computer software Foxpro, the patients who had come more than once for a subsequent or previous biopsy were identified. An attempt was made to look for progression, regression or a static nature of the lesion in the follow-up cases. Results: A total of 1778 cases were studied, and only 74 patients with endometrial hyperplasia and five cases of benign endometrial polyp had follow-up endometrial histopathology. Hyperplasia cases included 59 cases of simple hyperplasia, 10 cases of complex hyperplasia without atypia, and five cases with atypia. The predominant age for patients with all types of hyperplasias was 41 - 50 years. Progression to a higher grade was seen in 8.10%, regression to a lower grade was seen in 9.45%, lesions reverted to a normal pattern in 10.81% cases, and lesions persisted in 70.27% of the cases. A mixed pattern was seen in 54 cases, with predominant coexistent lesion being simple and complex hyperplasia without atypia. Conclusion: The fate

    Do the benefits of ovarian tissue cryopreservation outweigh the risks for patients seeking to preserve fertility before gonadotoxic treatment in various indications? In >90% of the patients undergoing cryopreservation of ovarian tissue, oncological treatment was associated with a reduced ovarian reserve and in 30% of patients, premature ovarian failure (POF) occurred within 5 years. Ovarian tissue cryopreservation is an effective fertility preservation option, especially for pre-pubertal patients and patients who have a short time between diagnosis of a disease and gonadotoxic treatment. This study retrospectively analysed ovarian function and fertility recovery rates, as well as ovarian tissue characteristics, of patients who underwent ovarian tissue cryopreservation at Erasme Hospital between 1999 and 2011. A total of 225 patients referred from 15 Belgian oncological units underwent cryopreservation of ovarian tissue before gonadotoxic therapy for malignant or benign diseases. There were 28 patients (12.4%) who died during follow-up due to recurrence of disease. One severe adverse event occurred during anaesthesia for ovarian tissue collection, leading to the death of the patient. Ovarian function and fertility outcomes were available for 114 patients including 13 girls who were pre-pubertal at the time of the procedure. Eight patients had undergone ovarian tissue transplantation in order to restore their fertility after remission of the disease. Breast cancer and haematological disease were the most frequent indications for ovarian tissue cryopreservation. Overall, 90% of post-pubertal patients were diagnosed with poor ovarian reserve (AMH 40 IU/ml). Breast cancer patients had a lower rate of POF than did post-pubertal patients with haematological diseases (11 versus 34.5%, respectively), despite the older age (mean 31 versus 23.5 years old, respectively) of the breast cancer patients. Ovarian function returned in 71 post-pubertal patients without the need for

    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.

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

    Full Text Available 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 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.

    Toxoplasmosis is a life-threatening infection in immunocompromised patients (ICPs). The definitive diagnosis relies on parasite DNA detection, but little is known about the incidence and burden of disease in HIV-negative patients. A 3-year retrospective study was conducted in 15 reference laboratories from the network of the French National Reference Center for Toxoplasmosis, in order to record the frequency of Toxoplasma gondii DNA detection in ICPs and to review the molecular methods used for diagnosis and the prevention measures implemented in transplant patients. During the study period, of 31,640 PCRs performed on samples from ICPs, 610 were positive (323 patients). Blood (n = 337 samples), cerebrospinal fluid (n = 101 samples), and aqueous humor (n = 100 samples) were more frequently positive. Chemoprophylaxis schemes in transplant patients differed between centers. PCR follow-up of allogeneic hematopoietic stem cell transplant (allo-HSCT) patients was implemented in 8/15 centers. Data from 180 patients (13 centers) were further analyzed regarding clinical setting and outcome. Only 68/180 (38%) patients were HIV(+); the remaining 62% consisted of 72 HSCT, 14 solid organ transplant, and 26 miscellaneous immunodeficiency patients. Cerebral toxoplasmosis and disseminated toxoplasmosis were most frequently observed in HIV and transplant patients, respectively. Of 72 allo-HSCT patients with a positive PCR result, 23 were asymptomatic; all were diagnosed in centers performing systematic blood PCR follow-up, and they received specific treatment. Overall survival of allo-HSCT patients at 2 months was better in centers with PCR follow-up than in other centers (P toxoplasmosis in HIV-negative ICPs and suggests that regular PCR follow-up of allo-HSCT patients could guide preemptive treatment and improve outcome.

    Full Text Available ABSTRACT: BACKGROUND AND OBJECTIVES: Perinatal mortality is the most sensitive index of the efficacy of not only antenatal, intranatal ca re and the quality of child health but also of socioeconomic status of the community. This study was aimed to assess the perinatal mortality rate and determinants of perinatal mortality at a tertiary care centre. METHODOLOGY: This retrospective hospital ba sed study included all the perinatal deaths (> 20 weeks / > 500 gms and neonatal deaths (within 28 days of birth during the period from 2008 to 2012. Data regarding maternal age, booking status, mode of delivery, sex of baby, birth weight, congenital ano malies and probable cause of death were collected. RESULTS: The PMR was found to be 47.95 per 1000 births. The PMR during 2008 was at peak with 58.72 per 1000 births which gradually showed a trend towards reduction with minimum at 39.57 per 1000 births dur ing 2012. The PMR was high among the women who were aged between 20 to 30 years while it was comparable in women with primi and multi parity. Most of the mothers were unregistered for ANC (64.84% and vaginal delivery was noted in 76.65% of the mothers. Th e mortality was found to be high in fetus 3.5 Kgs (1.24%. The commonest cause of PMR was placental abruption (17.6%. CONCLUSION AND INTERPRETATION: There Is a strong need to strengthen the educational and communi cation activities to create awareness about antenatal health care, identification of high risk mothers, timely referral, advanced life support of preterm neonates which would help in reducing the PMR

    A retrospective analysis was made to determine alternative diagnoses in patients with predominantly hypertensive episodes who were suspected of having pheochromocytoma but in whom this diagnosis was eliminated. Analysis of a random university hospital population referred over a period of 10 years. Episodic clinical presentations of pheochromocytoma symptoms combined with a comparison of baseline and episodic radioenzymatically determined levels of plasma free norepinephrine and epinephrine were examined, together with prospective levels of plasma free and sulfated dopamine. Out of 63 patients presenting with episodes of palpitations, headaches, flushing, sweating and hyperventilation (associated with hypertension in 49 patients, with hypotension in six patients and with alternating hyper- and hypotension in eight patients), 14 were diagnosed as having idiopathic hypovolemia, nine as having mastocytosis, nine as having an adrenal tumor, four as having neurogenic hypertension and one each with cocaine abuse and reninoma. Both baseline and symptomatic levels of plasma free norepinephrine and epinephrine remained within physiological limits (exceeding them moderately in baroreceptor dysfunction only), but all subgroups had a mean episodic increase over baseline in plasma dopamine sulfate (mean+/-SEM 16.7+/-5.9 to 53.2+/-19 pmol/ml; P pheochromocytoma in hemodynamic instability and frequent flushing formed a heterogeneous group, with plasma norepinephrine and epinephrine usually within physiological limits but an overall mean threefold increase in dopamine sulfate concentrations. With the various diagnoses of idiopathic hypovolemia, mastocytosis, neurogenic, secondary hypertension and cocaine abuse eliminated as a cause of pheochromocytoma-like symptoms, at least half of these patients still had unexplained, predominantly emotionally or proprioreceptive stimulation-provoked, bouts of hypertension. Sympathetic arousal dominated by an increase in dopamine sulfate without

    Full Text Available Background: Toxic alcohol poisonings are responsible for high mortality and morbidity in Russia. This study was aimed to evaluate the trends of harmful ethanol (EtOH drinking as well as methanol (MeOH, isopropanol (IPA and ethylene glycol (EG poisonings in the Middle Urals region of Russia. Methods: In this retrospective study, the medical records of patients poisoned with MeOH, IPA and EG as well as those with harmful heavy EtOH drinking admitted to Regional Poison Treatment Center in Yekaterinburg during the period of 2002 to 2014 were reviewed. Results: During this 13-year period, 17482 patients with acute poisoning (due to various toxic agents were admitted, which 2244 of them (12.8% were due to alcohol poisoning. Of all patients with acute poisoning, 502 cases died which 61 of them (12.2% were due to alcohol poisoning. Most of the alcohol poisoned patients were men (1658, 73.9%. The male proportion of EG poisoned patients was higher than poisoned patients with other types of alcohol. Harmful EtOH drinking constituted the majority of alcohol poisoning cases (2076, 92.5%. Patients with EG poisoning were relatively older while patients with heavy EtOH intake were significantly younger (P < 0.001. The highest mortality rate (35.9% was seen in patients with EG poisoning. During this period, heavy EtOH drinking had a slight increasing trend and MeOH poisoning had a sharp increasing trend. On the other hand, IPA poisoning had a constant trend and the trend of EG poisoning was decreasing. The majority of MeOH and IPA poisonings were due to ingestion of surrogate alcohols. Conclusion: Particular attention of health authorities should be directed towards alcohol drinking prevention measures as well as production and availability of surrogate alcohols in the community.

    Background Nontuberculous mycobacteria (NTM) are environmental organisms associated with a range of infections. Reports of NTM epidemiology are mainly focused on pulmonary infections and isolations, and extrapulmonary infections are less frequently described. Methods We conducted a retrospective study of NTM infections at the Bordeaux University Hospital, France, between January 2002 and December 2013. We used the microbiologic component of the American Thoracic Society/Infectious Diseases Society of America's pulmonary NTM disease criteria to define cases of pulmonary NTM, and patients with isolates from a normally sterile site were classified as having extrapulmonary disease. Results In our setting, 170 patients were included. Pulmonary cases predominated (54.1%), followed by skin and soft tissue infections (22.9%), disseminated cases (10.6%), lymphadenitis (7.7%), bone and joint infections (2.9%) and the remaining 1.8% catheter-related infections. Overall, 16 NTM species were isolated. Mycobacterium avium (31.8%) and M. intracellulare (20%) were the most common species identified, followed by M. marinum (13.5%), M. kansasii (10.6%), M. xenopi (9.4%), rapidly growing mycobacteria (9.4%) and other slowly growing mycobacteria (5.3%). In general, NTM isolates were largely prevalent in people older than 50 (62.4%); patients aged 1–10 year-old exclusively yielded M. avium from lymph nodes, almost cases having being diagnosed after 2007. Among the 121 patients with complete follow-up, 78 (64.5%), 24 (19.8%), and 19 (15.7%) were cured, experienced relapse, or died, respectively. Conclusion In our study, extrapulmonary NTM infections represented almost half of cases, consisting mainly in skin and soft tissue infections. The increase lymphadenitis cases in children after 2007 could be linked to the cessation of mandatory BCG vaccination in France. We observed similar cure rates (64%) between pulmonary and extrapulmonary infections. PMID:27959960

    This retrospective study aimed at determining the predicted risks of clinical and radiographic complications in primary teeth following traumatic dental injuries, according to injury type, severity and child's age. Data were collected from records of children treated at a Dental Trauma Center in Brazil for nine years. Records of 576 children were included; clinical sequelae were assessed in 774 teeth, and radiographic sequelae, in 566 teeth. A total of 408 teeth (52.7%) had clinical sequelae and 185 teeth (32.7%), radiographic sequelae. The type of injury with the highest number of clinical sequelae was the crown-root fracture (86.4%). Clinical sequelae increased with injury severity (p teeth with enamel fracture, and 26.0% (95%CI 14-40) for teeth with enamel dentin fracture as well as enamel dentin pulp fracture. Risk of periapical radiolucency was higher for teeth with enameldentinpulp fracture (61.1% 95%CI 35-82) and those with subluxation (15.8% 95%CI 10-22). Risk of premature loss was 27.3% (95%CI 13-45) for teeth with extrusive luxation, and 10.2% (95%CI 5-17) for those with intrusive luxation. The assessment of predicted risks of sequelae showed that teeth with hard tissue trauma tended to present color change, periapical radiolucency and premature loss, whereas teeth with supporting tissue trauma showed color change, abnormal position, premature loss and periapical radiolucency as the most common sequelae. Knowledge about the predicted risks of complications may help clinicians establish appropriate treatment plans.

    Certain dermatologic conditions are known to show seasonal variations in frequency, the reasons for which are unclear but in some cases may be attributable to changes in ambient weather conditions. The current study was conducted to determine whether seasonal trends might exist for dermatologic conditions including erythema multiforme, guttate psoriasis, erythema dyschromicum perstans (ashy dermatosis), pityriasis lichenoides, and pityriasis rosea. Data were derived from a 15-year retrospective review of electronic records from a large dermatopathology laboratory located in the mid-Atlantic region of the USA. Numbers of diagnoses per month and "per season" were determined. Pairwise comparisons of seasonal data were made using two-sample t-tests with significance set at P ≤ 0.05. Perniosis (chilblains) was significantly more common in winter and spring (P = 0.001). Hand, foot, and mouth disease was statistically more prevalent in summer and autumn (P = 0.028). Erythema multiforme was most common in spring and summer (P = 0.004). Grover's disease was most common in winter and spring (P = 0.000039). Guttate psoriasis was non-significantly more common in winter and spring (P = 0.076). No statistically significant seasonal variation was found for erythema dyschromicum perstans (P = 0.899), pityriasis rosea (P = 0.727), or pityriasis lichenoides (P = 0.366). This study found statistically significant seasonal trends for several dermatologic conditions. The study was primarily epidemiologic and was not intended to address histopathologic differences that might underlie the seasonal variations observed. However, further investigation of seasonal differences in the histopathology of erythema multiforme may prove interesting. © 2016 The International Society of Dermatology.

    2015-01-01

    Objectives The facial bones are the most noticeable area in the human body, and facial injuries can cause significant functional, aesthetic, and psychological complications. Continuous study of the patterns of facial bone fractures and changes in trends is helpful in the prevention and treatment of maxillofacial fractures. The purpose of the current clinico-statistical study is to investigate the pattern of facial fractures over a 4-year period. Materials and Methods A retrospective analysis of 1,824 fracture sites was carried out in 1,284 patients admitted to SMG-SNU Boramae Medical Center for facial bone fracture from January 2010 to December 2013. We evaluated the distributions of age/gender/season, fracture site, cause of injury, duration from injury to treatment, hospitalization period, and postoperative complications. Results The ratio of men to women was 3.2:1. Most fractures occurred in individuals aged between teens to 40s and were most prevalent at the middle and end of the month. Fractures occurred in the nasal bone (65.0%), orbital wall (29.2%), maxillary wall (15.3%), zygomatic arch (13.2%), zygomaticomaxillary complex (9.8%), mandibular symphysis (6.5%), mandibular angle (5.9%), mandibular condyle (4.9%), and mandibular body (1.9%). The most common etiologies were fall (32.5%) and assault (26.0%). The average duration of injury to treatment was 6 days, and the average hospitalization period was 5 days. Eighteen postoperative complications were observed in 17 patients, mainly infection and malocclusion in the mandible. Conclusion This study reflects the tendency for trauma in the Seoul metropolitan region because it analyzes all facial fracture patients who visited our hospital regardless of the specific department. Distinctively, in this study, midfacial fractures had a much higher incidence than mandible fractures. PMID:26734557

    Full Text Available Purpose: To describe the microbiological profile and clinical outcome in the eyes with culture-proven exogenous endophthalmitis. Methods: A retrospective analysis of 495 eyes diagnosed as exogenous endophthalmitis was performed over a period of 10 years. In all, aseptically collected aqueous and vitreous aspirates were cultured for bacteria and fungus using standard microbiological techniques. Gram-stain and KOH preparation of the specimens were also performed. The antibiotic susceptibility testing for bacterial isolates was performed by Kirby-Bauer disk diffusion method. The treatment was modified according to the antibiotic sensitivity profile. The final clinical ocular condition was divided into improved, stable or deteriorated. Results: Of 148 culture-proven endophthalmitis eyes, 137 (92.57% were referred from elsewhere, and 11 (7.43% belonged to our institute. Aetiologically, 76 (51.35% eyes were post-cataract surgery, 61 (41.22% were post-traumatic, 5 (3.38% eyes post-intravitreal anti-vascular endothelial growth factor injection, 5 associated with corneal diseases and 1 bleb-related endophthalmitis. In 31 (20.95% eyes, primary intravitreal antibiotics were given outside. The cultures revealed monomicrobial growth in 92.57% (n = 137 and polymicrobial growth in 7.43% (n = 11.

    Background Cebu has been one of the most leprosy endemic areas in the Philippines. Despite the high coverage rates of multiple drug therapy (MDT) and high BCG-vaccine coverage in children, leprosy control authorities believe that leprosy transmission and incidence (as evidence by continuing new case detection in both adults and children) have not declined as expected, once leprosy had been eliminated. In response to the concerns communicated by the authorities regarding ongoing leprosy transmission in Cebu, this study aims to examine the evidence for the hypothesized ongoing transmission, both in children and adults. Furthermore, it will be assessed which groups and areas are experiencing a continuing risk of leprosy infection; this can form a starting point for more targeted approaches to leprosy control. Methodology & Principal Findings Case records from 2000–2010 were retrospectively collected from the Leonard Wood Memorial Clinic archives, and all other clinics on the island where leprosy was treated. Between 2000 and 2010, 3288 leprosy cases were detected. The overall five year case notification rate (CNR) dropped significantly from 47.35 (2001–2005) to 29.21 cases (2006–2010) per 100.000 population. Smaller CNRs were reported for children; however the decline in child-CNR over the same period was minimal. Furthermore, no increase in median age of notification in children or adults was found between 2000 and 2010. Population-adjusted clustering of leprosy cases was mainly detected in urban and peri-urban areas. Conclusions & Significance Although the overall CNR declined significantly, CNR seems to be rather static in lower risk populations and areas. Cases are mainly found in urban areas, however CNRs in these areas decline at a much faster rate than in the lower endemic rural areas. A similar situation was found when comparing adults and children: CNRs observed in children were lower than in adults, but further decline (and elimination) of these

    Dengue fever (DF) is a frequently imported arthropod-borne infection in the United Kingdom but its broad range of clinical presentations makes it potentially unrecognized by clinicians. We conducted a 6-year retrospective case note review of laboratory confirmed DF patients in East London in the period from 1 January 2010 through 31 December 2015. Epidemiological, clinical and laboratory features of imported DF were described. Risk factors associated with viraemic DF presentations were assessed. Forty-four patients (4 from primary care clinics and 40 from three acute hospitals) were confirmed to have DF through RNA and/or IgM detection. In total, 86.4% (38/44) had primary infection compared to 13.6% (6/44) with secondary infection. Viraemic DF presentations accounted for 59.1% (26/44) of cases. The median age was 34 years (IQR 25-43). Most patients were males (68.2%, 30/44) and of non-white ethnicity (81.8%, 36/44). South Asia was the most frequent travel destination (52.3%, 23/44) followed by Southeast Asia (20.5%, 9/44). July-September was the peak season of presentation (43.2%, 19/44). The median interval between arrival in the UK and laboratory testing was 7 days (IQR 4-13). Arriving from abroad ≤ 7 days before molecular testing (age-adjusted odds ratios [OR] 16.98, 95% CI 2.43-118.75, P  =   0.004) and travel to South or Southeast Asia regions (age-adjusted OR 4.41, 95% CI 1.07-18.21, P  =   0.040) were associated with detectable viraemia at presentation. Only one DF patient met the WHO severity criteria. HIV serostatus was determined in 61.4% (27/44) of cases. Clinicians need to improve DF recognition as well as rates of HIV testing in tropical travellers. Region of travel and time since arrival from DF endemic settings may help clinicians optimize requests for molecular testing. Further research on the clinical and public health aspects of imported DF is needed.

    Full Text Available Abstract Background Breast cancer is more common in Western Countries compared to African populations. However in African population, it appears that the disease tends to be more aggressive and occurring at a relatively young age at the time of presentation. The aim of this study was to describe the trend of Breast Cancer in Northwestern Tanzania. Methods This was a retrospective study which involved all cases of breast cancer diagnosed histologically at Bugando Medical Center from 2002 to 2010. Histological results and slides were retrieved from the records in the Pathology department, clinical information and demographic data for patients were retrieved from surgical wards and department of medical records. Histology slides were re-evaluated for the histological type, grade (By modified Bloom-Richardson score, and presence of necrosis and skin involvement. Data was entered and analyzed by SPSS computer software version 15. Findings There were 328 patients histologically confirmed to have breast cancer, the mean age at diagnosis was 48.7 years (+/- 13.1. About half of the patients (52.4% were below 46 years of age, and this group of patients had significantly higher tendency for lymph node metastasis (p = 0.012. The tumor size ranged from 1 cm to 18 cm in diameter with average (mean of 5.5 cm (+/- 2.5, and median size of 6 cm. Size of the tumor (above 6 cm in diameter and presence of necrosis within the tumor was significantly associated with high rate of lymph node metastasis (p = 0.000. Of all patients, 64% were at clinical stage III (specifically IIIB and 70.4% had lymph node metastasis at the time of diagnosis. Only 4.3% of the patients were in clinical stage I at the time of diagnosis. Majority of the patients had invasive ductal carcinoma (91.5% followed by mucinous carcinoma (5.2%, Invasive lobular carcinoma (3% and in situ ductal carcinoma (0.3%.

    Snakebites are relatively rare medical emergency cases that might lead to serious consequences. This study aims to evaluate snakebite cases in terms of medical follow-up, antivenom therapy and antivenom reactions. Medical records of patients admitted to emergency department between January 1, 2006 and December 31, 2010 were retrospectively investigated. Snakebite-related cases of a total of 125 patients were included in the scope of the study. Of the total 125 cases, 54.4% were male and 45.6% were female. Most of cases (n: 65, 52%) were aged over 30 years, while the mean age was 34.87 ± 19.29 years. Snakebite-related applications to the emergency department were mostly seen in June with 27 cases. Upon admitting, all patients were recorded to be conscious and showing good general conditions; however, they suffered from pain and edema at the site of bite. Of all, 25 patients only suffered from bite injury and ecchymosis due to snakebite. The site of bite was upper extremities in 66 patients (52.8%), whereas it was lower extremities in 58 (46.4%). Of all, antivenom was unnecessary in 25 (20%) patients, while four antivenoms were administered to each of the 23 (18.4%) patients. Furthermore, six (4.8%) patients needed nine antivenom administrations for each. Anaphylaxis (n: 2, 1.6%), compartment syndrome (n: 2, 1.6%) and serum sickness (n: 1, 0.8%) encountered in remaining cases. Of all, 86 (68.8%) patients were hospitalized in the emergency department, while 25 (20.0%) patients were followed up by observation in emergency service. Only one patient was treated and followed up in intensive care unit. Implementation of antivenom therapy is considered unnecessary for the treatment of all snakebite cases. Antivenom reactions and number of related cases might be reduced by continuous close monitoring, appropriate prophylaxis and controlled slow infusion administration of medications. © The Author(s) 2012.

    Infection complications caused by gram-negative bacteria nowadays constitute the dominant mortality cause in severely burned patients. Pseudomonas aeruginosa is the most feared nosocomial pathogen among burn centers worldwide, with the highest mortality. The study involved adult patients hospitalized at the Intensive Care Unit at the Department of Burns and Reconstructive Surgery, University Hospital Brno, between the years 2000 and 2009. These patients were hospitalized for thermal injuries. Retrospectively we have evaluated the extent of the burned areas, ages, depth of injury at admission and at discharge or in dissection (histology) and length of hospitalization on the Intensive Care Unit. By completing regular swabs we monitored and evaluated the microbiological situation not only at the burned areas but also in the lower respiratory system, in the urinary tract and in the blood stream. The study involved a total of 640 adults hospitalized at the Intensive Care Unit at the Department of Burns and Reconstructive Surgery, University Hospital Brno, for burn trauma between the years 2000 and 2009. The average extent of the burned area in patients was 36.2% TBSA (2-97% TBSA), average age was 36.7% years (18-92 years), average length of hospitalization at the Intensive Care Unit was 27.1 days (1-151 days). We isolated a total of 2,958 strains of Pseudomonas aeruginosa (including repeated isolation of pseudomonas strains in the same patients) in these patients. The most frequently found of these was Pseudomonas aeruginosa isolated from the burned area (1,301 strains), from the lower respiratory system (651) and from the urinary tract (592 strains). During the monitored period the number of strains isolated in our patients increased (146 strains in 2000, 521 strains in 2009). Furthermore, we noticed increased resistance to all available antibiotics except Polymyxins. All of the Pseudomonas aeruginosa strains in the monitored years maintained 100% sensitivity to

    To evaluate the 3-year outcome in eyes with polypoidal choroidal vasculopathy (PCV) treated with photodynamic therapy with verteporfin. Retrospective study and review of the literature. We performed a retrospective study of patients with PCV who were treated with photodynamic therapy between January 2007 and December 2008. Patients were excluded if they had received photodynamic therapy before the study period, but those who received previous treatment with other modalities (thermal laser or intravitreal therapies) were allowed. The main outcome measures were best-corrected visual acuity, repeat photodynamic therapy, and recurrence of PCV at the end of Years 1, 2, and 3. We further conducted a systematic review of the literature using the terms "polypoidal choroidal vasculopathy" and "photodynamic therapy" and compared the visual outcome of studies over 3 years using meta-analytical methods. The retrospective study included 68 eyes. The mean best-corrected visual acuity was 0.73 ± 0.56 logMAR (20/107, Snellen equivalent) at baseline, 0.73 ± 0.70 logMAR (20/107, Snellen equivalent) at 1 year, 0.96 ± 0.76 logMAR (20/182, Snellen equivalent) at 2 years, and 1.07 ± 0.81 logMAR (20/235, Snellen equivalent) at 3 years. The cumulative recurrence rates of PCV were 16.1% (1 year), 34.9% (2 years), and 52.7% (3 years) and eyes with recurrence were more likely to suffer ≥3 lines loss compared with eyes without recurrence (63.2 vs. 17.6%, P = 0.006). The systematic review summarized results from 48 published studies and our retrospective study. The pooled analysis from 29 studies (316 eyes reporting the 3-year visual outcome) reported mean best-corrected visual acuity improvement of 0.115 logMAR at 1 year (n = 1,669), 0.066 logMAR at 2 years (n = 701), and 0.027 logMAR at 3 years (n = 316). Reported recurrence rates were 5.9% to 50.0% after 1 year, 9.1% to 83.3% after 2 years, and 40.0% to 78.6% after 3 years or longer of follow-up. The visual outcome in eyes with PCV

  7. Pregnancy-associated deaths: a 15-year retrospective study and overall review of maternal pathophysiology.

    Pregnancy-related death is defined by the International Classification of Diseases, Tenth Revision (ICD-10) as the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the cause of death. In the year 2000, a collaborative effort involving World Health Organization (WHO), UNICEF, and UNFPA estimated 660 maternal deaths in the United States. This averages 11 maternal deaths per 100,000 live births reported. Many pregnancy-associated deaths are not easily identified as such since the presence of a recent or current pregnancy may not be listed on the death certificate. Thus, the WHO estimates that in the United States, the maternal mortality is approximately 17/100,000 pregnancies. This is significantly higher than the goal set by the US Department of Health and Human Services in Healthy People 2010, which sets the target for maternal mortality at less than 3.3/100,000 live births. The most common causes of maternal death vary somewhat from region to region in the United States. They include pulmonary thromboembolism, amniotic fluid embolism, primary postpartum uterine hemorrhage, infection, and complications of hypertension including preeclampsia and eclampsia. Pulmonary disease, complications of anesthesia, and cardiomyopathy also are significant contributors to maternal mortality in some populations. The death of a pregnant or recently pregnant individual poses a wide scope of challenges to the forensic pathologist and investigator. The pathologist must have a broad knowledge of the physiologic and biochemical changes that occur during pregnancy, as well as the clinical and pathological manifestation of these changes. Conditions that may be "benign" in the nonpregnant individual may be lethal in the puerperal period. In addition, it should be kept in mind that deaths during pregnancy may be due to unnatural causes. Accident, homicide, and suicide must be ruled out in each case. The authors reviewed all forensic cases

    The trend towards laparoscopic surgery seen in other specialties has not occurred at the same pace in oesophagectomy. This stems from concerns regarding compromised oncological clearance, and complications associated with gastric tube necrosis and anastomotic failure. We present our experience of minimally invasive oesophagectomy (MIO) compared to open and hybrid surgery. We aim to ascertain non-inferiority of MIO by evaluating impact on survival, oncological clearance by resection margin and lymph node harvest and post-operative complications. Data were sourced retrospectively 2008-2015. Three approaches were studied. MIO (3-stage Mckeown), hybrid (2-stage Ivor Lewis, laparoscopy, thoracotomy) and open (2-stage Ivor Lewis). Five-year survival was 54.2%. Surgical approach had no significant impact on survival at any stage of disease (Stage 0/I p = 0.98; stage II p = 0.2; stage III p = 0.76). There was no statistically significant difference in oncological clearance by resection margins between procedures when compared by disease stage (p = 0.49). A higher number of nodes were harvested in hybrid [median 27.5 (6-65)] and open surgeries [median 26 (4-54)] than in MIO [median 20 (7-44)] (p > 0.01). Numbers of nodes resected did not impact risk of recurrence [recurrence, median 25 (6-54), no recurrence, 26 (4-65)] (p = 0.25). Anastomotic strictures (22.4%) and potential leaks (17.9%) were more common in MIO (strictures p > 0.01, leaks p = 0.08), although associated morbidity was lower. Respiratory complications were less common in MIO (2.9%) versus hybrid (13.3%) (p = 0.02). Wound infection and chyle leak were also lower (wound 1.5% MIO 3.5% open, p = 0.6; chyle leak 1.5% MIO, 6.7% hybrid, p = 0.2). Our results show no negative impact of MIO on survival or oncological clearance. Respiratory and wound complications are lower in MIO, but rates of anastomotic strictures and potential anastomotic leaks are increased. This may be due to the longer

    Objective: To study the circulation of monographs during the first three years of shelf life at an academic health sciences library. Method: A record was kept of monographs added to the circulating collection from mid-1994 to mid-1995. After three years, each monograph was located and the number of times it circulated during the first, second, and third year of shelf life determined by counting checkout stamps on the circulation slip. Results: Of the 1,958 monographs studied, 1,674 had complete data for the first three years of shelf life. Of those 1,674 titles, 81.48% circulated at least once. A total of 7,659 circulations were recorded; 38.69% occurred in the first year of shelf life, 32.37% in the second year, and 28.95% in the third year. The data did not fit the well-known 80/20 rule. Instead, approximately 38% of monographs accounted for 80% of circulation. A small percentage, 2.21%, of monographs accounted for a substantial percentage of circulation, 21.84%. Conclusions: A large percentage of the monographs circulated and use did not decline sharply with age within the first three years of shelf life, indicating a high demand for monographs at this academic health sciences library. These results, combined with the findings of earlier studies, suggested two possibilities. First, academic health sciences libraries might exhibit use of a higher percentage of monograph acquisitions than other types of libraries; or, second, a low monograph-to-user ratio might result in a higher percentage of monographs being used. Perhaps both factors contributed to the results found in this study. Further investigation would be needed to determine the extent to which library type and monograph-to-user ratio influenced monograph use. PMID:10783969

    Full Text Available The main objective in this study is to evidence the efficiency of the Peques System as a useful tool to diagnose, at an early stage, possible difficulties which will affect the academic performance. In a 3-year longitudinal study, the Perceptual-Motor Diagnostic System (Peques was applied to a sample of 149 participants (77 boys and 72 girls, who were beginning preschool education. Peques classified 38 children with a high risk to lose a year at primary school level. After a three-year follow-up (first primary school level, it was determined that 23 of the 127 who remained in the study (18%, had failed the first, second or third school year. From the high-risk group diagnosed by the Peques System, an 83% indeed lost a school year. These boys and girls had difficulties in different aspects, such as their information processing capacity, motor development, corporal image, Gestalt development and corporal coordination. We concluded that Peques System was able to predict the academic failure in the primary school level, based on the perceptual-motor development reached at preschool level. Further, based on this experience it is recommended to pay special attention to perceptual-motor development, since it plays a basic role in the academic success of boys and girls.

    The dentistry course in Sri Lanka is conducted in English, a second language for its students. A decade ago, English language proficiency was the key factor in predicting the academic performance of first year dental undergraduates. Since then, changes have been introduced to the teaching programme and examination format to minimise the effect of language proficiency on their performance. This study aimed at re-evaluating the factors influencing academic performance in a similar academic cohort. A total of 306 first year students in five consecutive academic years ranging in age from 20 to 24 years (77% of the total number registered, 36.3% men) were recruited, and a questionnaire was used to collect data regarding demographics, previous academic ability and perceived levels of difficulty of the first year course, English language and its sub-skills. Performances of the English language test and cumulative GPA of the first year course were used as objective indicators of language competency and academic performance respectively. The data were analysed using SPSS 11.5. Hierarchical Regression Analysis revealed that English language proficiency, gender and previous academic ability were the significant predictors of GPA. Students who received a lower GPA perceived English as considerably more difficult compared to the academic course itself; however, students who obtained a higher GPA perceived the opposite. Students' language competency remains the major predictor of academic performance, although previous academic ability and gender emerge as significant predictors. The perceived difficulty, however, of the dental course and of studying in English may also be predictors of student academic performance. © 2012 John Wiley & Sons A/S.

    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. The majority of our patients had type I acute NF

Antibiotics are largely prescribed during COPD exacerbation. Our hypothesis is that large broad-spectrum antibiotics are more and more frequently prescribed. Our results confirm this trend and highlight that the increase in large broad-spectrum use in COPD exacerbation is largely unexplained. Background: Acute COPD exacerbation (AECOPD is frequently due to respiratory tract infection, and the benefit of antipseudomonal antibiotics (APA is still debated. Health care–associated pneumonia (HCAP was defined in 2005 and requires broad-spectrum antibiotherapy. The main objectives are to describe the antibiotic use for AECOPD in intensive care unit and to identify factors associated with APA use and AECOPD prognosis. Methods: We conducted a monocentric, retrospective study on all AECOPDs in the intensive care unit treated by antibiotics for respiratory tract infection. Treatment failure (TF was defined by death, secondary need for mechanical ventilation, or secondary systemic steroid treatment. A multivariate analysis was used to assess factors associated with APA prescription and TF. Results: From January 2000 to December 2011, 111 patients were included. Mean age was 69 years (±12, mean

After April of 2010, we have not obtained any enough budget for new instruments. Therefore, we have not been able to install new Flare Monitoring Telescopes (FMT) in new countries, such as Algeria. On the other hand, however, we have continued international academic exchange through scientific and educational collaboration with mainly Peru, such as data-analysis training, holding scientific workshops etc. Additionally, in this year, King Saudi University of Saudi Arabia and CRAAG of Algeria have planned to build a new FMT in their university by their own budget. Therefore, we have started some collaboration in the field of technical advices of instruments and scientific themes etc. Moreover, Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) also offered us participation in the CHAIN-project. We would like to continue to consider the possibility of academic collaboration with such new positive developing nations, too.

    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.

    To compare trends and rates of cesarean section delivery by indication in one academic center. A retrospective analysis of the indications of all cesarean sections performed in Edith Wolfson Medical Center, Holon, Israel, a tertiary healthcare university facility, during 1997-2012 was done. Each delivery was assigned to the primary indication noted for that pregnancy, regardless of other indications reported. Whenever more than one indication was present, the principle indication chosen by the attending obstetrician was chosen for the analysis. The cesarean section rate gradually rose from 15.29% in 1997 to 21.10% in 2012, with an overall cesarean section rate of 20.66%. The cesarean section rate between 1997 and 2000 was 17.52%, between 2001 and 2004 was 18.5%, between 2005 and 2009 was 22.86%, and between 2009 and 2012 was 22.07% (p cesarean section (26.0%), non-reassuring fetal heart rate pattern (18.1%), malpresentation (16.9%), labor dystocia (8.8%), and suspected macrosomia (7.2%). Previous cesarean section persistently increased and was the leading indication throughout the years. Any attempt to reverse this trend must be based on reduction of the primary cesarean section rate. Copyright © 2016. Published by Elsevier B.V.

    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.

    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.

  15. 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

    To compare health and science students' demographic characteristics and learning approaches across different disciplines, and to examine the relationship between learning approaches and academic performance. While there is increasing recognition of a need to foster learning approaches that improve the quality of student learning, little is known about students' learning approaches across different disciplines, and their relationships with academic performance. Prospective, correlational design. Using a survey design, a total of 919 first year health and science students studying in a university located in the western region of Sydney from the following disciplines were recruited to participate in the study - i) Nursing: n = 476, ii) Engineering: n = 75, iii) Medicine: n = 77, iv) Health Sciences: n = 204, and v) Medicinal Chemistry: n = 87. Although there was no statistically significant difference in the use of surface learning among the five discipline groups, there were wide variations in the use of deep learning approach. Furthermore, older students and those with English as an additional language were more likely to use deep learning approach. Controlling for hours spent in paid work during term-time and English language usage, both surface learning approach (β = -0.13, p = 0.001) and deep learning approach (β = 0.11, p = 0.009) emerged as independent and significant predictors of academic performance. Findings from this study provide further empirical evidence that underscore the importance for faculty to use teaching methods that foster deep instead of surface learning approaches, to improve the quality of student learning and academic performance.

    Godek, Christopher P.

    2016-01-01

    Objective: Tissue liquefaction lipoplasty is a novel, low-energy method cleared for use in aesthetic body contouring and autologous fat transfer. This is a retrospective review of the clinical effectiveness and safety of a liquefaction lipoplasty system for liposuction and autologous fat transfer. Methods: A retrospective review was done evaluating all liquefaction lipoplasty procedures with or without autologous fat transfer performed by a single surgeon (March 2013 to June 2016). Patient demographics, operative details, and any complications were tabulated from patient charts. A typical case reported is presented with pre-/postoperative photographs. Results: Two hundred fifty-five consecutive liquefaction lipoplasty procedures were performed over 39 months. The average lipoaspirate volume was 1208 ± 991 mL and the average fat graft volume was 322 ± 277 mL. The overall complication rate was 9 of 255 (3.52%). There were 2 episodes of seroma (0.78%) that were aspirated and 2 episodes of cellulitis (0.78%) that responded to oral antibiotics. In the autologous fat transfer cohort, there were 5 of 103 (4.85%) cases of mild to moderate fat necrosis, with 1 patient requiring return to the operating room for removal of an oil cyst. No revisions of donor sites were required. Conclusions: Liquefaction lipoplasty appears safe for liposuction and autologous fat transfer, with a complication profile that is comparable with other widely used forms of suction-assisted liposuction. The liquefaction lipoplasty technology also provides potential time savings in the operating room that can minimize surgeon fatigue when harvesting large volumes of high-quality fat. Liquefaction lipoplasty appears to have advantages for both the patient and the surgeon, and further studies are underway. PMID:28077985

    Socioeconomic disadvantage is associated with an increased risk of adverse diabetes outcomes. In Switzerland, a country with theoretical universal healthcare coverage, people without health insurance face barriers in accessing to and in receiving standard quality care. The Geneva University Hospitals (HUG) have implemented policies aiming at reducing these gaps. We compared quality of diabetes care and ambulatory healthcare services utilization among insured and uninsured diabetic patients. This retrospective study linked health and administrative data of type 2 diabetic outpatients with at least one HbA1c test performed in 2012-2013 at HUG. Quality of care evaluation relied on processes (annual serum HbA1c, cholesterol and microalbuminuria tesing) and outcomes (HbA1c) assessment. Healthcare utilization was assessed by the number of ambulatory clinical and laboratory visits. Results were stratified by disease course (newly diagnosed versus prevalent diabetes). Of the 198 patients included, 80 (40.4 %) were uninsured. Both groups underwent annual testing of HbA1c, cholesterol, kidney function and microalbuminuria at comparably high rates and numbers of ambulatory visits did not significantly differ. After adjustments for age and sex, there were no significant differences in serum HbA1c between groups both in those with prevalent or with newly diagnosed diabetes. Initial medical intervention entailed comparable glycaemic improvement after 6 months in incident diabetes among insured and uninsured patients. This study did not find any difference in quality of diabetes care between insured and uninsured patients in a public hospital enforcing health-equity policies for access to and for delivery of standard diabetes care. It highlights the frontline role of public hospitals in contributing to care delivery equity even in countries with theoretical universal healthcare coverage.

    Cemented total knee arthroplasty has demonstrated high success rates at 10-12 years. Although many cementless designs have demonstrated inferior outcomes, hybrid fixation has not been studied in detail. We retrospectively reviewed 112 hybrid total knee arthroplasties (PCA-67 and Duracon-45) after clinical and radiographic review using the SF-12 and Knee Society Scores at an average 10-year follow-up. The revision rate was 4.5%: 4 occurred in patients with metal-backed patellae and 1 in a patient with infection. No revisions were performed for aseptic loosening of the femoral component. Hybrid total knee arthroplasty with these designs provided excellent clinical and radiographic performance at 10 years comparable to cemented series. Aseptic loosening and radiographic failure rates were 0% if patients with metal-backed patellae were excluded. The durability of hybrid fixation beyond 10 years deserves further study.

    The objective of this study was to compare detection rates of newborn drug exposure at an academic medical center transitioning from meconium to umbilical cord tissue toxicology testing. We performed an Institutional Review Board-approved retrospective chart review on all newborns (n=2072) for whom newborn drug testing was ordered at our academic medical center between June 2012 and August 2015 (in August 2013, umbilical cord tissue became the preferred specimen). Meconium toxicology testing was positive for at least one compound in 221 cases (21.3% of 1037 total specimens), with non-medical drug use identified in 85 cases (8.2%). Umbilical cord tissue toxicology testing was positive for at least one compound in 302 cases (29.2%), with non-medical drug use identified in 107 cases (10.3%). Of the cases involving non-medical drug use, the most common compounds detected were tetrahydrocannabinol and amphetamines. Non-medical drug use did not differ significantly between meconium and umbilical cord tissue, either as a total or for classes of drugs such as amphetamines, cannabinoids, and opiates. Maternal non-medical use of tramadol (not tested for in meconium) was identified in 5 cases (0.4%). There were significant differences in rate of detection of iatrogenic medications. Specifically, morphine, lorazepam, phenobarbital, and codeine were more commonly detected in meconium, while oxycodone was more commonly detected in umbilical cord tissue. Umbilical cord tissue toxicology testing yielded a similar detection rate compared to meconium testing. The use of umbilical cord tissue avoids detection of medications given to the neonate prior to meconium collection. Copyright © 2016 The Canadian Society of Clinical Chemists.

    The aim of this study was to analyze the effect of the inclusion of video triggers in conventional face-to-face lectures on the final grades of dental students in an oral biology course. The study consisted of two groups of students taking the course in two academic years at a dental school in Saudi Arabia: group 1, 2013-14 (control); and group 2, 2014-15. The total sample comprised 163 students (n=163; group 1: 71 and group 2: 92). Group 1 received lectures without any videos, whereas group 2 received lectures that included two to three videos of one to five minutes in duration with triggering effect (a video was shown every 10-15 minutes into the lecture). The final examination grades of the students were accessed retrospectively, and the data were compared with a chi-square test. The results confirmed that a higher number of students who received video triggering during lectures (group 2) performed better than their counterparts who did not receive video triggers (group 1); the difference was statistically significant (p<0.05). Among the group 2 students, 26% achieved a grade of A, and 37% achieved a grade of B. In contrast, only 7% of the group 1 students obtained a grade of A, and 31% achieved a grade of B. These results suggest that video triggers may offer an advantage over conventional methods and their inclusion in lectures can be a way to enhance students' learning.

    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.

    A bathtub drowning is one of the leading causes of death in a bathtub. The purpose of this study was to evaluate how reliable the drowning-related signs could be for identifying a bathtub drowning in the cases of death in the bathtub. Performing a retrospective review of 92 deaths in the bathtub in Maryland, 71.7 percent were the presence of bathtub drowning and 28.3 percent were the absence of bathtub drowning. Three leading contributory causes of death were cardiovascular disease, drug/alcohol-related death, and seizure disorder in both groups. There was a statistically significant difference between the groups in relation to a history of recovery from the water (95.5% and 38.4%, pbathtub drowning. A comprehensive investigation incorporating a thorough scene investigation, gathering of the victim's medical and psychosocial history, and a meticulous full autopsy is necessary to elucidate both the cause and manner of death in these cases of death in the bathtub.

    Full Text Available OBJECTIVE Study is to determine the incidence, indications of obstetric hysterectomy, maternal morbidity and maternal mortality associated with emergency obstetric hysterectomy at a tertiary hospital, Karad. This will help to highlight the lack of availability and inadequate utilisation of antenatal services. This will help to identify avoidable factors and stress factors; those need to organise health care services so as to improve maternal and foetal outcome. MATERIAL AND METHODS A retrospective analysis of 30 cases of emergency hysterectomies done for obstetric indications from JULY 2010 to JUNE 2015 was done. Indications for hysterectomy and causes of maternal morbidity and mortality were studied. RESULTS There were 30 cases of emergency hysterectomies amongst 19,635 deliveries during the period of study giving an incidence 0.15%, i.e. 1 in 654 deliveries. CONCLUSION The presence of risk factors like placenta previa, accreta, previous LSCS should facilitate referral or transfer of patients to a tertiary care hospital. When conservative measures like haemostatic sutures, internal iliac artery ligation, embolization is not feasible or has failed obstetric hysterectomy is performed without delay, in which delay would contribute to the maternal morbidity and in unfortunate cases mortality. Special provisions of blood components, dialysis facility and ventilator support associated with availability of experienced obstetrician, anaesthetist, neonatologist, physician and surgical services are necessary round the clock. Training of obstetrician in obstetric hysterectomy is very much necessary to reduce morbidity and mortality.

    Neurocysticercosis (NCC) is a common central nervous system (CNS) infection caused by Taenia solium metacestodes. The objective of this study is to describe the incidence of cysticercosis diagnosed at autopsies and describe the epidemiological and clinical characteristics of NCC. Retrospective study analyzing 6,500 reports of autopsies between 1977 and 1994 from a school hospital in Curitiba, PR, southern of Brazil. The following data was obtained, age, gender, site of cysticercosis, NCC as cause of death. The diagnosis of cysticercosis was established in 52 (0.8%) autopsies. From 1977 to 1987 (0.7%) and from 1988 to 1994 (1.1%). In the autopsies with cysticercosis 75% were male; age (mean ± SD) was 43 ± 20. NCC was present in 96% of cases, and seizures was the most frequent clinical manifestation. Asymptomatic cases in 54%. These data classify our area as hiperendemic, according with OMS criteria. The present study reinforces the necessity to develop adequate control programs.

    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.

    Full Text Available 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.

    Temporomandibular joint (TMJ) arthroscopy is a minimally invasive surgical approach for intra-articular TMJ diseases. Office-based arthroscopy using the smallest TMJ scope allows for good visualization, as well as the ability to lavage the joint in an office setting. This study aimed to assess the efficacy of an office-based TMJ arthroscopic technique. A retrospective evaluation of 363 patients with a TMJ disorder was performed. These patients underwent office-based arthroscopy using the OnPoint 1.2mm Scope System (Biomet Microfixation, Jacksonville, FL, USA) in Florida, USA, from July 2007. The following outcomes of the procedure were assessed: improvement in painless range of mandibular motion, pain on loading, and functional jaw pain; these were evaluated using a visual analog scale (VAS) over an average follow-up period of 263.81±142.1 days. The statistical analysis was performed using IBM SPSS Statistics version 20. Statistically significant improvements in TMJ pain and function, and other variables (P=0.001) were shown following TMJ arthroscopic lysis and lavage. Office-based arthroscopy using the OnPoint System was demonstrated to be a safe and efficient procedure for the treatment of patients with TMJ disorders as the first level of the algorithm of care.

    Enteric fever is a multisystemic infection which largely affects children. This study aimed to analyse the epidemiology, clinical presentation, treatment and outcome of paediatric enteric fever in Singapore. A retrospective review of children diagnosed with enteric fever in a tertiary paediatric hospital in Singapore was conducted from January 2006 to January 2012. Patients with positive blood cultures for Salmonella typhi or paratyphi were identified from the microbiology laboratory information system. Data was extracted from their case records. Of 50 enteric fever cases, 86% were due to Salmonella typhi, with 16.3% being multidrug resistant (MDR) strains. Sixty-two percent of S. typhi isolates were of decreased ciprofloxacin susceptibility (DCS). Five cases were both MDR and DCS. The remaining 14% were Salmonella paratyphi A. There were only 3 indigenous cases. Ninety-four percent had travelled to typhoid-endemic countries, 70.2% to the Indian subcontinent and the rest to Indonesia and Malaysia. All patients infected with MDR strains had travelled to the Indian subcontinent. Anaemia was a significant finding in children with typhoid, as compared to paratyphoid fever (P = 0.04). Although all children were previously well, 14% suffered severe complications including shock, pericardial effusion and enterocolitis. None had typhoid vaccination prior to their travel to developing countries. Enteric fever is largely an imported disease in Singapore and has contributed to significant morbidity in children. The use of typhoid vaccine, as well as education on food and water hygiene to children travelling to developing countries, needs to be emphasised.

    Objective The objective of this study was to investigate the association between contrast enema (CE) and clinical sepsis (CS) in premature babies (PB) and the role of antibiotics (ABs) in its prevention. Study Design A retrospective electronic chart review of preterm babies, who underwent CE during their stay in the neonatal intensive care unit. Group I includes CEs of babies exposed to AB during or within 48 hours of the procedure. Group II represents CEs of babies, not exposed to AB. Variables for both groups were collected and analyzed. Results There were 161 CEs performed in 133 babies. The overall incidence of CS after CE in preterm babies was 21/160 cases (13%). The incidence was significantly lower in Group I (1/79, 1.2%), compared with Group II (20/81, 24.7%) (p babies from Group II had positive blood culture and all 20 required AB after the CE. There were no statistical differences in the variables between the two groups. Conclusion There is a possible association between CE and CS in preterm babies. ABs given during or before the procedure prevent this complication.

    As part of an ongoing study to determine the basis for high prevalences of veno-occlusive disease, glomerulosclerosis, and chronic lymphoplasmacytic gastritis in cheetahs, a retrospective pathology survey of captive cheetahs in the Republic of South Africa (RSA) was conducted. The RSA population was selected because its genetic composition and captive management were similar to those of the cheetah population in U.S. zoos, in which these diseases are common. For this study, archived pathology materials at the University of Pretoria Faculty of Veterinary Sciences in Onderstepoort and the Faculty of Veterinary Science, MEDUNSA, from 69 cheetahs that died between 1975 and 1995 were reviewed, and prevalences of common lesions were compared with those in the U.S. population. Gastritis associated with Helicobacter-like organisms was the most prevalent disease, accounting for close to 40% of the mortalities, including several cheetahs cheetahs. RSA cheetahs also had adrenal cortical hyperplasia, cardiac fibrosis, lymphocytic depletion of the spleen, systemic amyloidosis, and splenic myelolipomas. The presence in the captive RSA cheetah population of the same unusual diseases that are common in U.S. cheetahs suggests a species predilection to develop these diseases in captivity.

    The aim was to determine the incidence of tinnitus, impaired hearing and musculoskeletal disorders among musicians and the relation to the number of practicing hours and/or the instrument type before the onset of symptoms. The study base consisted of students enrolled in the School of Music and Music Education at Göteborg University between the years 1980 and 1995. There were 407 of the 602 original students that answered a questionnaire (response rate of 68%). The questionnaire concerned exposure before and after the enrollment in the Music Academy, as well as onset of symptoms. The highest incidence of symptoms was found for reported tinnitus with a rate of 10.6 per 1000 years of instrumental practice. There was a relationship between exposure to the number of hours of instrumental practice and incidence of impaired hearing. Among the musculoskeletal symptoms the highest incidences per 1000 years of instrumental practice were pain in the neck and in the left shoulder with a rate of 4.4 and 4.6 disorders per 1000 years of instrumental practice, respectively. There was 2.4 times higher incidence for musculoskeletal disorders in the right hand/wrist and a 2.2 times higher incidence in the left elbow/forearm for musicians who practiced for 20 h or more per week before the onset of disorders compared to those who practiced fewer than 20 h per week when controlling for age and gender. Musicians with a violin or a viola as the main instrument had four times the incidence for right elbow/forearm disorder and twice the incidence of neck pain, pain in the right shoulder and the left elbow/forearm compared to those who had piano as the main instrument.

    Full Text Available Objective: Ventilator-associated pneumonia (VAP is the most common nosocomial infection in the intensive care units (ICUs. It causes prolonged hospital stay and increases mortality. In this study, we aimed to investigate the rate of VAP, causative microorganisms, and their antibiotic susceptibilities in anaesthesiology and reanimation ICU (ARICU. Material and Method: This retrospective study included patients who were admitted to 12-bed ARICU between January 2013 and December 2014. The detection of VAP was done according to Centers for Disease Control and Prevention criteria. The rate of VAP, VAP ratio, and ventilator utilization ratio (VUR were calculated according to guidelines of Turkish National Infection Surveillance Control Group. Endotracheal aspiration samples were collected and cultivated. The identification of the isolates was performed by using VITEK-2 automated system. Antibiotic susceptibilities were determined by the disc diffusion method according to the Clinical and Laboratory Standards Institute criteria. Results: VAP was determined in 16 of 359 patients who required invasive mechanic ventilation for longer than 48 hours and hospitalized in ARICU. VUR was 65%, VAP ratio was 4.5% and the rate of VAP was 3.3 per 1000 ventilator days. Seventeen microorganisms were isolated from endotracheal aspiration samples, including Acinetobacter baumannii (n=6, Pseudomonas aeruginosa (n=4, methicillin-resistant Staphylococcus aureus (n=4, Klebsiella pneumoniae, Enterobacter cloacae and Serratia marcescens. The most sensitive antibiotics for microorganisms are listed as follows; Acinetobacter baumannii: colistin, Pseudomonas aeruginosa: amikacin, carbapenems; Methicillin-resistant Staphylococcus aureus: linezolid, teicoplanin, vancomycin, trimethoprim sulfamethoxazole; Klebsiella and Enterobacteriaceae species: carbapenems, trimethoprim sulfamethoxazole, gentamicin.

    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

    2012-03-01

    Full Text Available Background: Tuberculosis is one of the most important causes of morbidity and mortality worldwide. Approximately 10-20% of tuberculosis is Extra-pulmonary tuberculosis (EPTB, which is much higher (50% in patients suffering from immunity defects such as AIDS. EPTB diagnosis is difficult mostly because of various clinical manifestations and aggressive procedures needed for its diagnosis. The main goal of this study was to determine the prevalence of EPTB in the north west of Iran and also to investigate the different clinical characteristics of the studied population, the various clinical manifestations and organ involvement of EPTB, as well.Methods: This study was carried out retrospectively using the data from Tabriz Tuberculosis and Lung Disease Research Center from 2007 through 2011. Questionnaires were designed to extract relevant information to describe characteristics of EPTB affected population and also various clinical manifestations and organ involvement of the disease among the patients.Results: The study included 203 EPTB cases notified from 2007 through 2011 including, 91 (44.83% males and 112 (55.17% females. The mean age of the patients was 46.55 ± 18.3. The main extra pulmonary involvements of the studied population were lymphadenitis (9.35%, pleural (7.39% and spinal (5.42% among males and lymphadenitis (17.24%, ocular (7.88%, pleural (6.40% and spinal (5.91% among females, respectively.Conclusion: Since EPTB diagnosis is a challenging and time sparing attempt even by the expert physicians, there is a need to perform further researches in order to identify the main clinical manifestations and organ involvement of EPTB in patients.

    2014-12-01

    Genitourinary fistula poses a public health challenge in areas where women have inadequate access to quality emergency obstetric care. Fistulas typically develop during prolonged, obstructed labor, but providers can also inadvertently cause a fistula when performing obstetric or gynecological surgery. This retrospective study analyzes 805 iatrogenic fistulas from a series of 5,959 women undergoing genitourinary fistula repair in 11 countries between 1994 and 2012. Injuries fall into three categories: ureteric, vault, and vesico-[utero]/-cervico-vaginal. This analysis considers the frequency and characteristics of each type of fistula and the risk factors associated with iatrogenic fistula development. In this large series, 13.2 % of genitourinary fistula repairs were for injuries caused by provider error. A range of cadres conducted procedures resulting in iatrogenic fistula. Four out of five iatrogenic fistulas developed following surgery for obstetric complications: cesarean section, ruptured uterus repair, or hysterectomy for ruptured uterus. Others developed during gynecological procedures, most commonly hysterectomy. Vesico-[utero]/-cervico-vaginal fistulas were the most common (43.6 %), followed by ureteric injuries (33.9 %) and vault fistulas (22.5 %). One quarter of women with iatrogenic fistulas had previously undergone a laparotomy, nearly always a cesarean section. Among these women, one quarter had undergone more than one previous cesarean section. Women with previous cesarean sections are at an increased risk of iatrogenic injury. Work environments must be adequate to reduce surgical error. Training must emphasize the importance of optimal surgical techniques, obstetric decision-making, and alternative ways to deliver dead babies. Iatrogenic fistulas should be recognized as a distinct genitourinary fistula category.

    Full Text Available Study programmes in landscape architecture have existed in Indonesia since the establishment of its first educational institution in 1963. This article presents a retrospective assessment which, hopefully, will encourage all those who arc concerned with landscape architecture in Indonesia to think about its future development. For the author, the article updates a previous paper about the status of the educational practice in Indonesia, delivered as a supporting document at the 4th IFLA Eastern Regional conference in Singapore in 1981, under the theme of 'Education'. The article begins with a systematic review of landscape architecture in Indonesia, and then presents results of six interviews with individuals chosen to represent a range of views from government, private practice, and educators. From both the review and interview results, questions are considered about people's perception and appreciation of landscape architecture in Indonesia as a branch of education and professional practice. Two specific priorities are highlighted. One is the recognised need for landscape architecture to make meaningful connections between people and the places they live in. The second focuses on the relationship between landscape education and the service and industrial sectors, with regard to the availability of job opportunities for its graduates. The article includes a profile of the profession in Indonesia and asks whether the profession is able to apply environmental approaches and techniques for community involvement in the planning and design process. Ideas arc discussed regarding the improvement of the quality of university graduates to produce educated human resources who will meet the current requirements of national development and the industrial sector.

    Studies comparing alternatives to ventriculoperitoneal (VP) shunting for treatment of hydrocephalus have often relied upon data from an earlier era that may not be representative of contemporary shunt survival outcomes. We sought to determine the shunt survival rate of our cohort and compare our results to previously published shunt survival and endoscopic third ventriculostomy (ETV) success rates. We identified 95 patients between 1 and 18 years of age, who underwent initial VP shunt placement between January 2001 and December 2010. Our study shows a shunt survival rate of 85% at 6 months and 79% at 2 years, for initial shunts in pediatric patients over 1 year of age in this cohort. The overall infection rate was 3%. This compares favorably with published success rates of ETV at similar time points as well as with the rate of infection. This suggests that ventricular shunting remains a viable alternative to ETV in the older child.

    Abstract Although randomized controlled studies reported an incidence of anesthesia awareness with recall ∼1 to 2 per 1000 (0.1–0.2%), recent data from the NAP5 study showed an incidence of only 1:19,600. Although in a prospective study many tools for anesthesia awareness detection can be used, a retrospective analysis requires a careful collection of information. The aim of the study was to evaluate the incidence of anesthesia awareness with recall in a cohort of cancer patients through a multisource retrospective analysis, and the clinical description, including the psychological outcome, of the cases detected. We also tested whether our retrospective analysis would be improved by a routinely psycho-oncological assessment. As secondary endpoints we evaluated the use of depth of anesthesia monitoring over a large cohort of patients, and the correlation between the brain monitoring and the incidence of awareness. We have carried out a 7-year retrospective analysis in a large cohort of cancer patients on the incidence of awareness with recall during general anesthesia. Of 35,595 patients assessed for eligibility, 21,099 were studied. We analyzed all data from the operative rooms’ database, the anesthesia records, and from the database of the surgical divisions. In addition we examined reports from psychologists and spontaneous reports to the quality team of the hospital. Two certain cases of awareness were detected, with an incidence of 1:10,550 (0.0095%). They occurred during elective surgery, in female patients without other risk factors. One case came from the report of a psychologist. In both episodes, brain monitoring was not applied and no long-term psychological sequelae were reported. Despite the limitations, our investigation suggests that the incidence of anesthesia awareness is very low, also in a specific cohort of patients, such as the cancer patients, and even when the depth of anesthesia monitoring is rarely used. The limitations caused by both

    To investigate the epidemiological characteristics of colorectal cancer (CRC) in patients under 50 years of age across two institutions. Records of patients under age 50 years of age who had CRC surgery over a 16 year period were assessed at two institutions. The following documents where reviewed: admission notes, operative notes, and discharge summaries. The main study variables included: age, presenting symptoms, family history, tumor location, operation, stage/differentiation of disease, and post operative complications. Stage of disease was classified according to the American Joint Committee on Cancer TNM staging system: tumor depth; node status; and metastases. CRC was found in 180 patients under age 50 years (87 females, 93 males; mean age 41.4 ± 6.2 years). Young patients accounted for 11.2% of cases during a 6 year period for which the full data set was available. Eight percent had a 1(st) degree and 12% a 2(nd) degree family CRC history. Almost all patients (94%) were symptomatic at diagnosis; common symptoms included: bleeding (59%), obstruction (9%), and abdominal/rectal pain (35%). Evaluation was often delayed and bleeding frequently attributed to hemorrhoids. Advanced stage CRC (Stage 3 or 4) was noted in 53% of patients. Most tumors were distal to the splenic flexure (77%) and 39% involved the rectum. Most patients (95%) had segmental resections; 6 patients had subtotal/total colectomy. Poorly differentiated tumors were noted in 12% and mucinous lesions in 19% of patients of which most had Stage 3 or 4 disease. Twenty-two patients (13%) developed recurrence and/or progression of disease to date. Three patients (ages 42, 42 and 49 years) went on to develop metachronous primary colon cancers within 3 to 4 years of their initial resection. CRC was common in young patients with no family history. Young patients with symptoms merit a timely evaluation to avoid presentation with late stage CRC.

    In Europe, trauma admissions and in particular hip fractures are on the rise. In recent years, health care systems have placed particular emphasis, including financial incentives, on delivering patients quickly and safely to surgery. At our unit, we have observed that hip fracture patients appear to be at significant risk of mortality even up to a year following injury. This study reviews a consecutive population of hip fracture patients to identify predictors of excess risk. Four hundred and sixty-five consecutive patients were treated over a 2-year period at our district general hospital with no ward-based orthogeriatricians. Follow-up was for 1 year following hip fracture admission. Statistical analysis of variables and their influence on 1-year mortality were performed by calculating odd's ratio (OR) using a logistic regression model and a p value year was 50 %. Following hip fracture, we found an overall 1-year mortality rate of 15.1 %. Patients with a time to surgery ≥36 h were at significantly increased risk of mortality even up to 1 year. We did not identify a further reduction in mortality in those operated on within 24 h. Raised ORs (p > 0.05) were found with increasing comorbidity, surgery type, independence on discharge, alcohol ingestion, history of smoking, readmission and several biochemical markers. Minimising mortality risk, even over the longer term, should begin on admission with prompt optimisation of any acute medical or biochemical abnormalities, followed by early surgery and intensive rehabilitation to maintain patients' functional independence.

    As the popularity of long-acting reversible contraception increases, so does the need for accurate data on method continuation in diverse clinical settings. We determined 2-year continuation rates for the levonorgestrel 52-mg intrauterine device, the copper T380A intrauterine device, and the 68-mg etonogestrel contraceptive implant in an academic healthcare system with mixed-payer reimbursement. The purpose of this study was to examine the proportion and characteristics of women who continue intrauterine device and implant use to 2 years and to relate continuation to device type when controlling for patient characteristics. This retrospective chart review assessed University of Utah Healthcare System patients who had an intrauterine device or contraceptive implant inserted between January 1, 2004, and December 31, 2012. We identified users and dates of insertions and removals by querying billing, medication, and procedural data in the Electronic Data Warehouse. Multivariable Poisson regression was conducted to estimate incidence risk ratios and to relate the probability of 2-year continuous use to device type. Data on 8603 device insertions were obtained with the following distribution: levonorgestrel 52-mg intrauterine devices (6459; 75.1%), copper T380A intrauterine devices (1136; 13.2%), and 68-mg etonogestrel implant (1008; 11.7%). Two-year continuation rates were 77.8%, 73.1%, and 75.9%, respectively. There was no statistical difference in 2-year continuation between levonorgestrel 52-mg intrauterine device users (adjusted risk ratio, 1.1; 95% confidence interval, 1.0-1.1) and 68-mg etonogestrel implant users (adjusted risk ratio, 1.1; 95% confidence interval, 1.0-1.1) compared with copper device users, after we controlled for age, Hispanic ethnicity, payer type, and year of insertion. Older-age, self-pay, or public payer insurance (reference commercial payer) and Hispanic ethnicity were associated with 2-year continuation. Three-quarters of women with an

    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.

    Full Text Available Objective: Epidemiological studies are essential on the prevention and resolution of health problems. The aim of this study was to investigate skin biopsies in Çankırı region. Methods: A total of 2128 patients admitted to our dermatology outpatient clinic and their 2128 lesions were retrospectively analyzed. The demographic characteristics, the localizations and types of lesions were obtained from dermatology and pathology records for the statistical analyses. Pathology slides were retrospectively re-examined and diagnoses were confirmed. Results: Melanocytic nevus was the most common diagnosis of the skin tumors (27%, n=574 followed by cystic tumor, soft fibroma/acrochordon and psoriasis. In general, cheeks and lips were the most common tumor location (21.7%. The youngest population was the patients with molluscum contagiosum (25.00±11.04 years and the oldest group of patients was the ones with squamous cell carcinoma (SCC (71.69±12.79 years. The most common malignant tumor was basal cell carcinoma (BCC (74%, n=92. BCCs were mostly localized on nose (35.9%. SCC was the second most common malignant tumor (26%, n=32. There was no statistically significant difference between two malignant tumor groups in terms of age. Conclusion: Malignant tumor ratios were consistent with the literature in Çankırı region. Increase in epidemiological researches may provide the opportunity to compare with other studies and facilitate health management planning.

    The 1-year dog toxicity study is no longer required by certain pesticide regulatory jurisdictions, including the United States and the European Union. Health Canada's Pest Management Regulatory Agency (PMRA) examined its current requirement for this study to determine if it could be refined or eliminated. A retrospective analysis was conducted to examine the impact of the 1-year dog study on human health risk assessment. The Acceptable Daily Intake (ADI), a measure of the amount of a pesticide in food that can be ingested on a daily basis over a lifetime without an appreciable health risk, was the metric for this analysis. For 143 pesticides evaluated by the PMRA between 2008 and 2015, the supporting toxicology databases were examined to determine if other toxicology studies were protective of the findings in the 1-year dog study. When this criterion was not met, further investigation was undertaken to determine the potential impact of not having the 1-year dog study. For most of the pesticides, effect levels in the 1-year dog study were not substantially different from those in other toxicology studies, when considering factors such as dose-spacing and known experimental variability. The results of this analysis suggest that absence of the 1-year dog study would have minimal impact on the assessment of human health risk. Therefore, Health Canada's PMRA has removed the routine requirement for the 1-year dog study from its pesticide data requirements.

    The impact of ablative oral cancer surgery was studied, with particular reference to recurrence and nodal metastasis, to assess survival probability and prognostic indicators and to elucidate if ethnicity influences the survival of patients. Patients who underwent major ablative surgery of the head and neck region with neck dissection were identified and clinical records were assessed. Inclusion criteria were stage I-IV oral and oropharyngeal malignancies necessitating resection with or without radiotherapy from 2004 to 2009. All individuals had a pre-operative assessment prior to the surgery. The post operative assessment period ranged from 1 year to 5 years. Survival distributions were analyzed using Kaplan-Meier curves. 87 patients (males:38%; females:62%) were included in this study, with an age range of 21-85 years. Some 78% underwent neck dissections while 63% had surgery and radiotherapy. Nodal recurrence was detected in 5.7% while 20.5% had primary site recurrence within the study period. Kaplan-Meier survival analysis revealed that the median survival time was 57 months. One year overall survival (OS) rate was 72.7% and three year overall survival rate dropped to 61.5%. On OS analysis, the log-rank test showed a significant difference of survival between Malay and Chinese patients (Bonferroni correction p=0.033). Recurrence-free survival (RFS) analysis revealed that 25% of the patients have reached the event of recurrence at 46 months. One year RFS rate was 85.2% and the three year survival rate was 76.1%. In the RFS analysis, the log-rank test showed a significant difference in the event of recurrence and nodal metastasis (p<0.001). Conservative neck is effective, in conjunction with postoperative radiotherapy, for control of neck metastases. Ethnicity appears to influence the survival of the patients, but a prospective trial is required to validate this.

    We determined whether physical education (PE) taught by specialists contributed to academic development and prevention of obesity in elementary school children. Our 2-year longitudinal study involved 620 boys and girls initially in grade 3 in Australia, all receiving 150 minutes per week of PE. One group (specialist-taught PE; n = 312) included 90 minutes per week of PE from visiting specialists; the other (common-practice PE; n = 308) received all PE from generalist classroom teachers. Measurements included percentage of body fat (measured by dual-emission x-ray absorptiometry) and writing, numeracy, and reading proficiency (by government tests). Compared with common-practice PE, specialist-taught PE was associated with a smaller increase in age-related percentage of body fat (P = .02). Specialist-taught PE was also associated with greater improvements in numeracy (P < .03) and writing (P = .13) scores. There was no evidence of a reading effect. The attenuated age-related increases in percentage of body fat and enhanced numeracy development among elementary school children receiving PE from specialists provides support for the role of PE in both preventive medicine and academic development.

    Recently, conventional interviews have been replaced with the multiple mini-interviews (MMI) for medical student selection in Korea. We first introduced the MMI as a new admissions tool in Korea. The aim of this study is to determine whether the MMI accurately predicts academic achievement on both written and performance-based examinations during the first 2 years of medical school. The original scores of each station were standardized to T-scores in the candidates group. Three cohorts of students were included depending upon the year they entered medical school. Pearson's correlations were calculated to estimate the correlations between MMI scores and academic achievements. Additional correlated factors were run through multiple stepwise linear regression analysis to estimate predictive validity. There were no differences between T-scores or grade point averages (GPA) among the cohorts. The correlation coefficients between total MMI scores and academic achievement in Year 1 and the Year 2 performance-based examinations ranged from 0.17 to 0.43. Station 1 significantly predicted academic achievement over the second year. Station 3 significantly predicted only performance-based examination performance over the second year. MMI is a useful tool to assist with medical student selection. In particular, critical thinking, professionalism, and presentation and communication skills may be meaningful topics for predicting academic achievements, especially in performance-based subjects.

    Studies indicate that soil science enrollment in the USA was on the decline in the 1990s and into the early 2000s (Baveye et al., 2006; Collins, 2008). However, a recent study indicated that in the seven years from 2007 through 2014 the number of soil science academic majors, at both the undergraduate and graduate levels, was on the increase (Brevik et al., 2014). However, the Brevik et al. (2014) study only looked at the number of soil science majors, it did not look at other important trends in soil science enrollment. Therefore, this study was developed to investigate enrollment numbers in individual soil science classes. To investigate this, we collected data from ten different American universities on the enrollment trends for seven different classes taught at the undergraduate level, introduction to soil science, soil fertility, soil management, pedology, soil biology/microbiology, soil chemistry, and soil physics, over a 10 year time period (2004-2005 to 2013-2014 academic years). Enrollment in each individual class was investigated over five (2009-2010 to 2013-2014) and 10 (2004-2005 to 2013-2014) year trends. All classes showed increasing enrollment over the five year study period except for soil physics, which experienced a modest decline in enrollment (-4.1% per year). The soil chemistry (23.2% per year) and soil management (10.1% per year) classes had the largest percentage gain in enrollment over the five year time period. All classes investigated experienced increased enrollment over the 10 year study period except soil biology/microbiology, which had an essentially stable enrollment (0.8% enrollment gain per year). Soil physics (28.9% per year) and soil chemistry (14.7% per year) had the largest percentage gain in enrollment over the 10 year time period. It is worth noting that soil physics enrollments had a large increase from 2004-2005 through 2009-2010, then dropped to and stabilized at a level that was lower than the 2009-2010 high but much

    Full Text Available Background: Proper knowledge of the patterns of sexually transmitted diseases (STDs in different geographical regions is necessary for evolving proper strategies for control of these diseases. Aims: To study the pattern of STDs and to analyze the changes during a ten-year period from 1990 among patients attending Medical College Hospital, Kottayam Methods: Case records of 686 patients with STDs who attended the outpatient wing of the Department of Dermatology and Venereology were studied. Results: There were 504 males and 182 females in the total of 686 patients. Marital contact alone was reported by 123 (67.6% female patients. Genital ulcer diseases (GUDs accounted for the maximum number of STDs, with 504 cases (73.5%, followed by condyloma acuminatum (17.5% and gonorrhea (10.1%. Forty-three patients had multiple infections. The total number of patients during the first year of study was 129, while it was 41 during the last year. Bacterial STDs showed a striking reduction in numbers. The decline was less marked in the case of viral STDs. Conclusion: The majority of patients had genital ulcer diseases. Spouses were the most common source of infection for female patients. There was a marked decline in the number of patients with various STDs during the ten-year period. The decline was more evident in the bacterial STDs resulting in an apparent increase of the viral STDs towards the end of the period of study.

    We assessed with cross-approximate entropy menstruation onset versus moon phases in 74 women with 980 menstrual cycles over a calendar year. In defiance of traditional beliefs and contrary to what some researchers have argued with short-term research work, in this long-term study we did not find any synchrony of lunar phases with the menstrual cycle.

    During the 25-year period 1970-1994, 680 patients were diagnosed with neck sprain due to causes other than car accidents at the Emergency Room of the University Hospital Groningen. The purpose of the present study was to analyse the prevalence, groups at risk and trends in patients with neck sprain. We defined the population as patients diagnosed with neck sprain that was not due to a car accident (NCA). The binominal test was used to obtain measures of statistical significance, deltax was used to obtain both the total increase in the number of neck sprain victims over the whole period (1970-1994) and the relative contribution of successive 5-year periods. Over the 25-year period a steady increase in the number of patients was observed from 55 in 1970-1974 to 241 in 1990-1994. The highest prevalence was found among 15- to 19-year-olds (3.92 per 10,000), followed by 10- to 14-year-olds (3.40 per 10,000). The major causes of neck sprain NCA were accidental falls (25%), sports injuries (24%) and bicycling injuries. Across the life span, the male: female ratio was 0.63. Ten percent of patients were treated as inpatients. The increase in neck sprain NCA can be only partly attributed to increased media attention. The reduction of working hours resulting in more leisure time activities, which in turn increases the exposure time in at risk situations, and the awareness of both patients and physicians is discussed.

    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.

    Full Text Available The impact of ablative oral cancer surgery was studied, with reference to recurrence and nodal metastasis,  survival probability and prognostic indicators and to determine if ethnicity influences the survival of patients. Patients who underwent major ablative surgery of the head and neck region with neck dissection were identified and assessed. Those with stage I-IV oral and oropharyngeal malignancies necessitating resection with or without radiotherapy from 2004 to 2009 were included in this study. All individuals had a pre-operative assessment and post operative assessment. Survival distributions were analyzed using Kaplan-Meier curves. Eighty seven patients (males: 38%; females: 62% were included in this study, with an age range of 21-85 years. Some 78% underwent neck dissections while 63% had surgery and radiotherapy. Nodal and primary site recurrence was 5.7% and 20.5%. The median survival time was 57 months. One year Overall Survival (OS rate was 72.7% and three year overall survival rate 61.5%. The log-rank test showed a significant difference of survival between Malay and Chinese patients (Bonferroni correction p=0.033. Recurrence-Free Survival (RFS analysis revealed that 25% of the patients have reached the event of recurrence at 46 months. The three year survival rate was 76.1%.

    Full Text Available Objectives: We planned this study with the aim of obtainingknowledge about epidemiological characteristics of gynecologicalmalignancies followed up in our hospital.Materials and methods: In our study we analyzed 231patients that were operated with the appraisal diagnosis ofgynecological cancer in Gynecology and Obstetrics Departmentof Dicle University Medical Faculty between the datesof 2001, January and 2011, November.Results: The mostly diagnosed gynecological malignancywas ovarian cancers among the gynecological cancersseen in the first group compassing the period between theyear 2001 and the first half-term of the year 2006. 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

    Amyotrophic lateral sclerosis (ALS) is a rare, rapidly progressive neurodegenerative disease. Despite wide variability in the incidence and prevalence of ALS, there is evidence of positive temporal trends and an increase in incidence with age. The aim of this study was to conduct a detailed epidemiological investigation of ALS in Cyprus. All registered Cypriot ALS patients in the Republic of Cyprus from January 1985 until December 2014 were included. Socio-demographic information was extracted from patient files. The study identified 179 ALS patients, of whom 7 had a positive family history. The mean age at onset was 58.6 years and a slight male predominance was observed. Average annual crude incidence was 1.26 cases/100,000 person-years and at the beginning of 2015, prevalence of ALS was 7.9 cases/100,000 population. Both incidence and prevalence displayed an increasing trend, even after age-standardization of incidence rates. Incidence, prevalence and main socio-demographic characteristics of ALS in Cyprus were similar to those of other European countries, without any geographic clustering of the disease. Additionally, an increased incidence through the years was confirmed. However, observations such as a higher male prevalence and a younger mean age of onset compared to published literature require further investigation. © 2017 S. Karger AG, Basel.

    Frequent use (FU) of hospital services impacts on patients and health service expenditure. Studies examining FU in emergency departments and inpatient settings have found heterogeneity and the need to differentiate between potentially preventable FU and that associated with ongoing management of complex conditions. Psychosocial factors have often been reported as underpinning or exacerbating the phenomena. Most FU studies have been limited by time, to a single study site, or restricted to specific diagnoses or patient groups. This study provides a comprehensive description of adult patient characteristics, conditions and risk factors associated with FU, based on admissions to the five public hospitals in the Northern Territory (NT) of Australia over a nine year period. The study population is distinctive comprising both Aboriginal and non-Aboriginal patients. Data on all inpatient episodes in NT public hospitals between 2005 and 2013 was analysed to identify patients with any FU (four or more episodes within any 12-month period) and measure FU duration (number of FU years) and intensity (mean number of episodes per FU year). Pregnancy, alcohol-related and mental health condition flags were assigned to patients with any episode with relevant diagnoses during the study period. Multivariate analysis was used to assess factors associated with any FU, FU duration and FU intensity, separately for Aboriginal and non-Aboriginal patients. Of people with any inpatient episodes during the study period, 13.6% were frequent users (Aboriginal 22%, non-Aboriginal 10%) accounting for 46.6% of all episodes. 73% of frequent users had only one FU year. Any FU and increased FU duration were more common among individuals who were: Aboriginal; older; female; and those with a pregnancy, alcohol or mental health flag. Having two or more alcohol-related episodes in the nine-year period was strongly associated with any FU for both Aboriginal (odds ratio 8.9, 95% CI. 8.20-9.66) and non

    2015-01-01

    The faculty at member schools and colleges of the Association of American Veterinary Medical Colleges (AAVMC) are critical for continued progress in veterinary medicine. The success of those faculty members over the past 50 years has positioned veterinary medicine to engage an ever-widening array of opportunities, responsibilities, and societal needs. Yet the array of skills and accomplishments of faculty in academic veterinary medicine are not always visible to the public, or even within our profession. The quality and the wide range of their scholarship are reflected, in part, through the according of national and international awards and honors from organizations relevant to their particular areas of expertise. The goal of this study was to illustrate the breadth of expertise and the quality of the faculty at 34 schools/colleges of veterinary medicine by examining the diversity of organizations that have recognized excellence in faculty achievements through a variety of awards.

    An estimated 136 000 concussions occur per academic year in high schools alone. The effects of repetitive concussions and the potential for catastrophic injury have made concussion an injury of significant concern for young athletes. The objective of this study was to describe the mechanism of injury, symptoms, and management of sport-related concussions using the High School Reporting Information Online (HS RIO) surveillance system. Descriptive epidemiology study. All concussions recorded by HS RIO during the 2008-2009 academic year were included. Analyses were performed using SPSS software. Chi-square analysis was performed for all categorical variables. Statistical significance was considered for P concussions were recorded. The most common mechanism (76.2%) was contact with another player, usually a head-to-head collision (52.7%). Headache was experienced in 93.4%; 4.6% lost consciousness. Most (83.4%) had resolution of their symptoms within 1 week. Symptoms lasted longer than 1 month in 1.5%. Computerized neuropsychological testing was used in 25.7% of concussions. When neuropsychological testing was used, athletes were less likely to return to play within 1 week than those for whom it was not used (13.6% vs 32.9%; P < .01). Athletes who had neuropsychological testing appeared less likely to return to play on the same day (0.8% vs 4.2%; P = .056). A greater proportion of injured, nonfootball athletes had computerized neuropsychological testing than injured football players (23% vs 32%; P = .02) When computerized neuropsychological testing is used, high school athletes are less likely to be returned to play within 1 week of their injury. Concussed football players are less likely to have computerized neuropsychological testing than those participating in other sports. Loss of consciousness is relatively uncommon among high school athletes who sustain a sport-related concussion. The most common mechanism is contact with another player. Some athletes (1

    Subtalar arthrodesis is a common therapy for subtalar joint disorders. In this article, we evaluate the effect of subtalar arthrodesis on the ankle and hindfoot joints. Fifty patients (33 men and 17 women) underwent subtalar arthrodesis between January 1, 1996, and August 31, 2011. The 36-item Short-Form Health Survey and American Orthopaedic Foot and Ankle Society ankle hindfoot scores were used for clinical evaluation. Radiographic analysis included assessment of degenerative changes and ankle and hindfoot joint function in the frontal and sagittal planes. Thirty-seven patients (27 men and 10 women; mean age, 42.6 years) were followed up for an average of 9.2 years (range, 2-17 years). The mean ± SD 36-item Short-Form Health Survey score improved from 30.21 ± 7.19 before surgery to 78.50 ± 12.23, and the American Orthopaedic Foot and Ankle Society ankle hindfoot score increased from 50.32 ± 12.39 to 73.14 ± 15.44. Degenerative changes in the talonavicular, calcaneocuboid, metatarsocuboid, and ankle joints occurred. The talar-vertical angle was positively related to the tibial-plantar minimal angle (affected side: r = 0.56; P < .01; healthy side: r = 0.46; P < .01). The difference in hindfoot height is positively related to the difference in tibial-plantar minimal angle (r = 0.54; P < .01). Subtalar arthrodesis is effective treatment for subtalar joint disease but could induce joint degeneration and ankle joint motion limitation related to talar declination and hindfoot height.

    Insulin pump failure and/or malfunction requiring replacement have not been thoroughly investigated. This study evaluated pump replacement in children and adolescents with Type 1 diabetes using insulin pump therapy. Data were collected for all participants younger than 19 years, starting insulin pump therapy before 31 December 2013. For each child, age, disease duration, date of insulin pump therapy initiation, insulin pump model, failure/malfunction/replacement yes/no and reason were considered for the year 2013. Data were returned by 40 of 43 paediatric centres belonging to the Diabetes Study Group of the Italian Society of Paediatric Endocrinology and Diabetology. In total, 1574 of 11 311 (13.9%) children and adolescents with Type 1 diabetes were using an insulin pump: 29.2% Animas VIBE(™) , 9.4% Medtronic MiniMed 715/515(™) , 34.3% Medtronic MiniMed VEO(™) , 24.3% Accu-Check Spirit Combo(™) and 2.8% other models. In 2013, 0.165 insulin pump replacements per patient-year (11.8% due to pump failure/malfunction and 4.7% due to accidental damage) were recorded. Animas VIBE(™) (22.1%) and Medtronic MiniMed VEO(™) (17.7%) were the most replaced. In a large cohort of Italian children and adolescents with Type 1 diabetes, insulin pump failure/malfunction and consequent replacement are aligned with rates previously reported and higher in more sophisticated pump models. © 2016 Diabetes UK.

    Full Text Available Context: The need to perform reporting of renal biopsies of antineutrophil cytoplasmic antibodies (ANCA-associated vasculitides in a more uniform manner required relook at our eight-year data. Aims: To document detailed renal histopathology of pauci-immune rapidly progressive glomerulonephritis (RPGN and also to seek any significant differences in renal histology of C-ANCA-positive, P-ANCA-positive, and ANCA-negative patients. Materials and Methods: A detailed analysis of the histopathologic features of renal biopsies of 48 patients in whom a diagnosis of pauci-immune glomerulonephritis was concluded on renal biopsy and who presented clinically as rapidly progressive renal failure was done. Statistical Analysis Used: One-way ANOVA and Pearson Chi square tests. Results: Compared with ANCA +ve patients, the ANCA -ve patients were much younger (46.85 ± 16.12 years vs 34.28±15.94 years. No significant differences were found between renal lesions of C-ANCA, P-ANCA, and ANCA-negative patients, except for diffuse tubular atrophy which was more severe and more frequently present with P-ANCA positivity (P value=0.013. Conclusions: Pauci-immune RPGN (irrespective of ANCA status is a relatively rare disorder in patients who are undergoing the renal biopsy at our institute, constituting 2% of all renal biopsies submitted. It is mandatory to have ANCA serology status during reporting of a kidney biopsy showing pauci-immune crescentic or necrotizing glomerulonephritis. Also, if a uniform reporting strategy is followed throughout the country, the studies from this vast country will be comparable.

    The aim of this study was to assess the clinical performance of CAD/CAM partial coverage posterior restorations made by CEREC AC Bluecam system after 5 years. 159 ceramic partial coverage posterior restorations were placed in 109 patients in a private practice. The restorations were made using CEREC AC Bluecam with CEREC Blocs or Empress CAD blocks. The clinical performance of the restorations was evaluated with modified California Dental Association (CDA) guidelines, gingival and plaque indices, probing pocket depth, and bleeding on probing in a period of 5 years. Patients' satisfaction was assessed using visual analogue scale. The Kaplan-Meier method was used to analyze survival probability of the restorations (α=0.05). The restorations included 102CEREC Blocs and 57 Empress CAD. The survival rates of CEREC Blocs and Empress CAD blocks were 96.0% and 94.6%, respectively (P=0.67). A total of 7 (4.5%) failures were found. The failures were not significantly influenced by restoration size, type and position of teeth. The ceramic fracture was significantly more in nonvital teeth (P=0.04). The periodontal parameters were not significantly different between the restored and control teeth except plaque index. The mean score of patients' satisfaction was 94.4 ± 8.1. Chair-side CEREC AC ceramic partial coverage posterior restorations were clinically successful restorations with mean survival rate of 95.5% after 5 years. Conservative chair-side CAD/CAM ceramic restorations with less reduction of tooth structure can be a successful restorative method with acceptable survival rate and patient's satisfaction.

    The aim of the study was to assess the clinicopathological characteristics of patients with verrucous carcinoma (VC) of the vulva. We reviewed data on the age, disease course, clinical manifestation, pathologic diagnosis, treatment, and follow-up of patients with vulvar VC who were treated at Tianjin Medical University General Hospital and cases that were reported in the Chinese and English literature during the past 20 years. Six cases were identified in Tianjin Medical University General Hospital, the mean age of patients was 55 years, and their mean disease course was 26 months. Primary symptoms were exophytic neoplasm with pruritus and/or pain. Surgical treatment included wide local excision, simple vulvectomy, and radical vulvectomy with or without lymph node dissection in the groin. Vulvar VC occurred simultaneously with vulvar intraepithelial neoplasia in 2 cases and well-differentiated squamous cell carcinoma in 2 cases. The mean follow-up was 16.8 months with no recurrence in those 6 cases. During the 20-year period, 20 and 41 cases were reported in Chinese and English literature, respectively. Three cases were misdiagnosed with giant condyloma acuminatum in China. One case (1/20) was reported with coexistent squamous carcinoma in Chinese literature and 8 cases (8/41) in the English literature. The recurrence rate was 12.5% (2/19) and 17.5% (7/40) in Chinese and English literature, respectively. Vulvar VC is a distinct type of slow-growing, nonmetastatic tumor with unclear etiology. These tumors should be distinguished from giant condyloma acuminatum and well-differentiated squamous cell carcinoma. Surgery is the most effective treatment.

    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.

    Full Text Available Background. Malaria is a major public health problem in Ethiopia where an estimated 68% of the population lives in malarious areas. Studying its prevalence is necessary to implement effective control measures. Therefore, the aim of this study was to determine seven-year slide positive rate of malaria. Methods. A retrospective study was conducted at Metema Hospital from September 2006 to August 2012. Seven-year malaria cases data had been collected from laboratory registration book. Results. A total of 55,833 patients were examined for malaria; of these, 9486 (17% study subjects were positive for malaria. The predominant Plasmodium species detected was P. falciparum (8602 (90.7% followed by P. vivax (852 (9%. A slide positive rate of malaria within the last seven years (2006–2012 was almost constant with slight fluctuation. The age groups of 5–14 years old were highly affected by malariainfection (1375 (20.1%, followed by 15–29 years old (3986 (18.5%. High slide positive rate of malaria occurred during spring (September–November, followed by summer (June–August. Conclusion. Slide positive rate of malaria was high in study area. Therefore, health planners and administrators should give intensive health education for the community.

    The major aims of this study were to identify factors that may predict the diagnostic conversion from major depressive disorder (MDD) to bipolar disorder (BP) and to evaluate the predictive performance of the bipolar spectrum disorder (BPSD) diagnostic criteria. The medical records of 250 patients with a diagnosis of MDD for at least 5 years were retrospectively reviewed for this study. The diagnostic conversion from MDD to BP was observed in 18.4% of 250 MDD patients, and the diagnostic criteria for BPSD predicted this conversion with high sensitivity (0.870) and specificity (0.917). A family history of BP, antidepressant-induced mania/hypomania, brief major depressive episodes, early age of onset, antidepressant wear-off, and antidepressant resistance were also independent predictors of this conversion. This study was conducted using a retrospective design and did not include structured diagnostic interviews. The diagnostic criteria for BPSD were highly predictive of the conversion from MDD to BP, and conversion was associated with several clinical features of BPSD. Thus, the BPSD diagnostic criteria may be useful for the prediction of bipolar diathesis in MDD patients. Copyright © 2014 Elsevier B.V. All rights reserved.

    Copeland, Robert A

    2016-02-01

    The drug-target residence time model was first introduced in 2006 and has been broadly adopted across the chemical biology, biotechnology and pharmaceutical communities. While traditional in vitro methods view drug-target interactions exclusively in terms of equilibrium affinity, the residence time model takes into account the conformational dynamics of target macromolecules that affect drug binding and dissociation. The key tenet of this model is that the lifetime (or residence time) of the binary drug-target complex, and not the binding affinity per se, dictates much of the in vivo pharmacological activity. Here, this model is revisited and key applications of it over the past 10 years are highlighted.

    Conclusions: We found a high incidence of GTD in the non-Asian population (1 in 415. Most patients who had been diagnosed with GTD on ultrasound were in the first trimester. Accuracy of ultrasound diagnosis is 40 % over a 5 year audit period. The main ultrasound findings of GTD were cystic changes and mixed echogenic echoes. Patients who were undiagnosed on ultrasound but had histological diagnosis of GTD had missed miscarriage as the predominant ultrasound diagnosis. Most patients were registered with the screening centre within six weeks of the histological diagnosis. [Int J Reprod Contracept Obstet Gynecol 2015; 4(6.000: 1887-1890

    Full Text Available Malignant diseases have been believed to be more common in some areas of Eastern Morocco, but until now, cancer patterns have not been reported for this region. In this paper we present for the first time the cancer prevalence analysis in Eastern Morocco.Cross-sectional study carried out among all patients diagnosed and/or treated with cancer at the Hassan II Regional Oncology Center (ROC since it was established in October 2005 until December 2012. The ROC is the only hospital specialized in cancer care in Eastern Morocco.A total of 8,508 cases of cancer were registered among residents in Eastern Morocco, with a female to male ratio of 2.1. The mean age at diagnosis was 53.9 ± 15.2 years (median age = 53 years. Thus, unlike in Western countries, cancer in Eastern Morocco afflicts younger population. The areas of Eastern Morocco did not differ significantly by mean age at diagnosis (p = 0.061. However, these regions differed significantly by sex ratio (p < 0.001. The highest sex ratio was observed in Figuig, with a female to male ratio of 3.1 (75.4% of the registered case were females, followed respectively by Taourirt, Oujda-Angad, Berkane, Nador-Driouch and Jerada. Clear variation in the distribution of cancer types between areas of Eastern Morocco was observed, both in males and females (p < 0.001. Furthermore, the areas of Eastern Morocco differed significantly by cancer prevalence (p < 0.001. The highest age-standardized five-year prevalence proportion was observed in Oujda-Angad with 420.2 per 100,000, followed respectively by Berkane (311.4, Jerada (287.8, Taourirt (269.3, Nador-Driouch (213.6 and Figuig (194.4. Trends in the five-year prevalence proportions decreased in Oujda-Angad, Berkane and Jerada throughout the study period, while an increasing trend was observed in Nador-Driouch, Taourirt and Figuig.For the first time, our study presents the pattern and distribution of diagnosed cancers in Eastern Morocco.

    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.

    Malnutrition is common in haemodialysis (HD) and is linked to poor outcomes. This study aimed to describe changes in body composition after the initiation of HD and investigate whether any routinely collected parameters were associated with these changes. The study cohort came from the HD population of a single centre between 2009 and 2014. Body composition measurements were obtained from a database of bioimpedance results using the Body Composition Monitor (BCM), while demographics and laboratory values came from the renal unit database. Primary outcomes were changes in normohydration weight, lean tissue mass and adipose tissue mass over the two years after HD initiation. A total of 299 patients were included in the primary analyses, showing an increase in adipose tissue, loss of lean tissue and no significant change in normohydration weight. None of the routinely collected parameters were associated with the lean tissue changes. Loss of lean tissue over the first year of dialysis was associated with increased mortality. The results showing loss of lean tissue that is not limited to those traditionally assumed to be at high risk supports interventions to maintain or improve lean tissue as soon as possible after the initiation of HD. It highlights the importance of monitoring nutrition and the potential for routine use of bioimpedance. PMID:27827911

    The purpose of the present review was a comparison of the abortions caused by EAV and EHV-1 viruses over the 34 years. A total of 452 tissues samples from aborted fetuses (347) or foals (105) stillborn or newborn that died within 72 hours were investigated. The material for the examinations came from different farms located throughout Poland. The tissue homogenates were examined by using virus isolation test in RK-13 and Vero cell lines and the cytopathic agent was confirmed as EHV-1 by the direct fluorescent antibody test or as EAV by the indirect fluorescent antibody test. The study indicated that EAV was isolated (104 cases, 23%) almost as equally often as EHV-1 (116 cases, 25.6%). Both, equid herpes virus-associated abortion and the abortion induced by EAV were characterized by cyclicity. The percentage of EAV and EHV-1 isolation alternately reduced and increased, but the increase of isolation of one virus was accompanied by the decrease of the other. The domination of one virus over the other occurred in cycles of a few years.

    Anaerobic bacteremia (116 cases) represented 5.4% of the total cases of bacteremia in the Hospital Nuestra Señora de Covadonga of Oviedo, Spain, during a five-year period (1981-1985). Microbiologic data for all 116 cases and clinical data for 63 patients were analyzed. A total of 129 isolates were identified as gram-negative bacilli (45.7%), gram-positive bacilli (38.0%), gram-positive cocci (14.0%), and gram-negative cocci (2.3%). Bacteroides fragilis and Clostridium perfringens were the most frequently occurring species. Anaerobic polymicrobial infection was detected in 21 patients. The most relevant clinical features were fever (79%), metastatic abscesses (33%), anemia (27%), septic shock (25%), and disseminated intravascular coagulation (6%). The overall mortality rate was 25.4%, and the factors associated with a poor prognosis were age over 60 years, lack of adequate surgical treatment, severe underlying disease, metastatic foci, and polymicrobial and/or nosocomial infection.

    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.

    Tuberculosis (TB) kills one child every 5 min. Childhood TB is given low priority in most national health programmes particularly in TB-endemic areas. TB among children is an indicator of a recent transmission of the disease in the community. Treatment outcome results serve as a proxy of the quality of treatment provided by a health care system. In Ethiopia, data on treatment outcomes of childhood TB are limited. The aim of the study was to determine the treatment outcomes of childhood TB in a hospital setting in Addis Ababa. The study was conducted during June to August 2014. The data of 491 children treated for TB in Zewditu Memorial Hospital during a 5 year (2009-2013) was analysed. TB was diagnosed using standard methods. Demographic and clinical data including type of TB, TB-HIV co-infection and treatment outcomes were collected from registry of the TB clinic. Treatment outcome definitions are used according to the World Health Organization. Of the 491 children, 272(55.4 %) were females, 107(21.8 %) were under 5 year old, 454(92.5 %) of them were new cases. The types of TB were extra-pulmonary tuberculosis (EPTB) 243(49.5 %) and 248(50.5 %) pulmonary tuberculosis (PTB). Of the PTB cases, 42(16.9 %) were sputum smear positive. Of the 291 children tested for HIV, 82(28.2 %) were positive. The overall treatment success rate was 420(85.5 %) and the poor treatment outcome was 71(14.5 %). Of the children with poor treatment outcome, 9(1.8 %) died, 3(0.6 %) defaulted from treatment, 2(0.4 %) were treatment failure and 55(11.2 %) were transferred out. Males and females had similar treatment success rates of 85.8 % and 85.3 %, respectively. Infants under one year had significantly lower treatment success rate of 72.7 % compared to those above 1 years of age of 86.5 % (P Treatment success rate ranged from 78.0 to 92.6 % during the study period. Associated factors for treatment outcome were age above 5 years (AOR = 0.59, 95 % CI: 0.62-0.97) and

    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.

    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

    Full Text Available Background: Septic arthritis is a disabling and potentially life-threatening condition that requires prompt diagnosis and treatment. The most important risk factors are joint prosthesis, pre-existing joint disease and immunosuppressive drugs. The aim of our study therefore was to revaluate all septic arthritis cases discharged from our Rheumatologic Unit in the last 12 years, to assess the risk factors, the clinical and laboratory characteristics, the causative microorganisms and its possible increase in frequency. Methods: The medical records of 42 consecutive patients with septic arthritis discharged from our Rheumatology Unit between January 1995 and December 2006 were reviewed. The patients ranged in age from 23 to 90 and there isn’t gender predominance. Septic arthritis was diagnosed based on the finding of purulent material in the joint space and/or the isolation of a bacterial pathogen from joint fluid. Demographic data, risk factors, co-morbidity, clinical manifestations, time interval between symptoms onset and diagnosis, treatment and laboratory data including serum white blood cell count, erythrocyte sedimentation rate (ESR, C reactive protein (CRP, synovial white blood cells and culture results were analysed. We considered these parameters in the whole population and in two different age groups (≤60, >60 and tried to determine if there was a change of microorganisms involved in septic arthritis during the years. Results: Of 42 patients, 47% were aged 60 and younger. Only 10 patients were admitted to our unit before 2001. A predisposing factor was recorded in 90,5% of cases: 15 patients had rheumatoid arthritis, 8 were diabetic, 6 had seronegative arthritis, 4 had a connective tissue disease, 8 patients had a prosthetic infection and 3 were subjected recently to arthrocentesis. We found that patients aged 60 and younger were more frequently affected by joint disease and had a synovial white blood cell count lower than patients

    Kickboxing is a group of full-contact combat sports that allows both kicking and punching from a standing position. Despite its popularity, there is a scarcity of published data elucidating the injury epidemiology in kickboxing. To determine the injury incidence, describe the injury pattern, and identify potential risk factors for injury in kickboxing. Descriptive epidemiology study. Data describing fight outcomes and injuries sustained during professional and amateur kickboxing contests over a 15-year period were obtained from the official records of the Nevada Athletic Commission, United States. Injury incidence rates and rate ratios were calculated with 95% confidence intervals (95% CIs) per 1000 athlete-exposures (AEs) and per 1000 minutes of exposure. The injury pattern was described using frequencies and proportions of injuries by anatomic region and type of injury. In addition, Poisson mixed-effects generalized linear modeling was used to examine the multivariate relationships between injury incidence rates and potential risk factors. The sample consisted of 481 unique fighters competing across 57 events, 976 AEs, 9562 minutes of exposure, and 380 injuries. The mean ± SD age of the fighters was 29.0 ± 5.3 years (range, 15-48 years). The overall injury incidence rates were 390.1 injuries (95% CI, 351.9-431.4) per 1000 AEs and 39.7 injuries (95% CI, 35.8-43.9) per 1000 minutes of exposure. The most commonly injured anatomic regions were the head (57.8%) and lower extremity (26.1%), while the most common types of injury were laceration (70.6%) and fracture (20.6%). Professional fighters were 2.5 times more likely to get injured compared with amateurs (rate ratio, 2.51; 95% CI, 1.39-4.55), while defeated fighters were 3.5 times more likely to get injured compared with winners (rate ratio, 3.48; 95% CI, 2.73-4.44). Injuries are frequent and often significant in kickboxing, and better injury surveillance is strongly recommended. The scarcity of good

    Full Text Available The research on prophylaxis and treatment of hepatitis C has been performed for more than 30 years, with outstanding achievements. The discovery and confirmation of hepatitis C virus (HCV was a milestone for how humans discovered new life. Emphasis on HCV molecular biology, infection immunity, and pathogenesis is the basic rule for scientific research on infectious diseases. PEG-IFN combined with ribavirin as the standardized antiviral treatment has been a great success; this combination therapy achieves a sustained viral response more than 80% in Chinese people, which is a typical example for successful clinical application of cytokines. Direct-acting antiviral agent(DAA or combined application has made it possible to cure all patients infected with hepatitis C, which is the most successful example for reference. Persistent viral infection and maintenance of immune homeostasis under certain conditions are the results of the interaction between the host and the virus, and the development of vaccines will be continued.

    Full Text Available We present a  clinical case of ichthyosis hystrix, a rare genetic ichthyosiform dermatosis. Specifics of the disease are related to the complexity of differential diagnosis and verification of the diagnosis, because clinical manifestation of ichthyosis hystrix is similar with that of verrucous epidermal nevus. Clinical particulars of both nosologies are characterized by bizarre and widespread skin lesions of spicular hyperkeratotic growth, located along Blaschko lines. The exclusive feature of the clinical case described is a  long-term (20 years clinical and laboratory monitoring of the patient. The literature review provides brief information on etiology, pathogenesis, clinical features, differential diagnosis, and pathomorphology of ichthyosis hystrix and verrucous epidermal nevus.

  4. The Elaborated Intrusion Theory of desire: a 10-year retrospective and implications for addiction treatments.

    May, Jon; Kavanagh, David J; Andrade, Jackie

    2015-05-01

    Ten years after the publication of Elaborated Intrusion (EI) Theory, there is now substantial research into its key predictions. The distinction between intrusive thoughts, which are driven by automatic processes, and their elaboration, involving controlled processing, is well established. Desires for both addictive substances and other desired targets are typically marked by imagery, especially when they are intense. Attention training strategies such as body scanning reduce intrusive thoughts, while concurrent tasks that introduce competing sensory information interfere with elaboration, especially if they compete for the same limited-capacity working memory resources. EI Theory has spawned new assessment instruments that are performing strongly and offer the ability to more clearly delineate craving from correlated processes. It has also inspired new approaches to treatment. In particular, training people to use vivid sensory imagery for functional goals holds promise as an intervention for substance misuse, since it is likely to both sustain motivation and moderate craving.

    2011-05-01

    The Chernobyl Forum Report from the 20th anniversary of the Chernobyl nuclear power plant disaster concluded that mental health effects were the most significant public health consequence of the accident. This paper provides an updated review of research on the psychological impact of the accident during the 25 year period since the catastrophe began. First responders and clean-up workers had the greatest exposure to radiation. Recent studies show that their rates of depression and post-traumatic stress disorder remain elevated two decades later. Very young children and those in utero who lived near the plant when it exploded or in severely contaminated areas have been the subject of considerable research, but the findings are inconsistent. Recent studies of prenatally exposed children conducted in Kiev, Norway and Finland point to specific neuropsychological and psychological impairments associated with radiation exposure, whereas other studies found no significant cognitive or mental health effects in exposed children grown up. General population studies report increased rates of poor self-rated health as well as clinical and subclinical depression, anxiety, and post-traumatic stress disorder. Mothers of young children exposed to the disaster remain a high-risk group for these conditions, primarily due to lingering worries about the adverse health effects on their families. Thus, long-term mental health consequences continue to be a concern. The unmet need for mental health care in affected regions remains an important public health challenge 25 years later. Future research is needed that combines physical and mental health outcome measures to complete the clinical picture. Copyright © 2011 The Royal College of Radiologists. Published by Elsevier Ltd.

    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.

    Prior research has shown that students' previous grade point average (GPA) is the best predictor for future academic success. However, it can only partly predict the variability in dental school performance. The aim of this study was to assess the predictive value of multiple mini-interviews (MMI) as an admission criterion by comparing them with the academic performance of dental students over a two-year period. All incoming undergraduate dental students at the King Abdulaziz University Faculty of Dentistry (KAUFD) during academic year 2013-14 were invited to participate in MMI. Students rotated through six objective structured clinical exam (OSCE)-like stations for 30 minutes total and were interviewed by two trained faculty interviewers at each station. The stations were focused on noncognitive skills thought to be essential to academic performance at KAUFD. The academic performance of these students was then followed for two years and linked to their MMI scores. A total of 146 students (71 males and 75 females) participated in an interview (response rate=92.9%). Most students scored in the acceptable range at each MMI station. Students' total MMI score, ambitions, and motives were significant predictors of GPA during the two years of follow-up (pacademic performance of undergraduate dental students.

    Adequate use of different learning strategies is one of the most important prerequisites of academic success. The actual use of learning strategies is the result of an interaction between individual and situational variables. Against this background we conducted a longitudinal study with first year medical students to investigate whether individuals show different patterns in their use of learning strategies and whether these patterns change during the first academic year. Medical students (N=175, 58% female) were surveyed three times in their first academic year regarding their use of learning strategies. A hierarchical cluster analysis (Ward) was conducted in order to identify groups of students with different patterns of learning strategies. We identified four different patterns in approaches to learning among novice medical students ("easy-going", "flexible", "problematic" and "hardworking" learners). Compared to their peers, the problematic learners had the worst final school grades. In addition changes in the use of learning strategies were identified, most of them occurred during the first term. Students start their academic studies with different patterns of learning strategies; the characteristics of these patterns change during the first academic year. Further research is necessary to better understand how individual and situational variables determine students' learning.

    Full Text Available Objective: This hospital-based retrospective cohort study was undertaken with a view to determine the epidemiological trend of measles in Lagos State, Nigeria Methods: Medical records of clinically diagnosed measles patients from nine referral public hospitals in Lagos State between 1998 and 2007 were retrieved, transcribed and reviewed. Data were analyzed using standard methods. Results: A total of 35,500 clinically confirmed cases and 835 deaths (case fatality rate = 2.35%/10 years were recorded. The mean incidence was estimated at 19 cases per 100,000 population/year. A consistent seasonality pattern of measles was observed for the study period. The under-fives accounted for the highest reported cases (76.30% while, the under-1 year recorded highest mortality (53.8%. Notable shift of measles vulnerability from under-1year to under-fives was observed. Although there was significant difference between cases and deaths among the age groups (p0.05. Conclusion: This study recorded high incidence and case fatality of measles, which poses serious public health threat. Poor demographic data collection and storage were revealed thus, computerization of medical records for collection, storage and retrieval of data is imperative for adequate planning and control of measles imperil in Nigeria.

    The aim of this study was to determine whether inadequate prenatal care is associated with increased risk of preterm birth among adolescents. We selected a random sample of women under age 20 years with singleton pregnancies delivering in Washington State between 1995 and 2006. Multivariate logistic regression was used to assess the association between prenatal care adequacy (percent of expected visits attended, adjusted for gestational age) and preterm birth. Of 30,000 subjects, 27,107 (90%) had complete data. Women without prenatal care had more than 7-fold higher risk of preterm birth (n = 84 [24.1%]; adjusted odds ratio [aOR], 7.4), compared with those attending 75-100% of recommended visits (n = 346 [3.9%]). Women with less than 25%, 25-49%, or 50-74% of expected prenatal visits were at significantly increased risk of preterm birth; risk decreased linearly as prenatal care increased (n = 60 [9.5%], 132 (5.9%], 288 [5%]; and aOR, 2.5, 1.5, and 1.3, respectively). Inadequate prenatal care is strongly associated with preterm birth among adolescents. Copyright (c) 2010 Mosby, Inc. All rights reserved.

    Full Text Available Oral cancer is the eighth most common cancer worldwide and presents a serious health problem in countries with higher alcohol consumption and smoking. The aim of the present study was to analyze the survival rates of patients with oral cancer diagnosed at a single center in Bulgaria. The clinical records of patients with oral cancer admitted to the Clinic of Maxillofacial surgery, University Hospital “St. George”, Plovdiv, Bulgaria, from 2004 till 2013 were reviewed. Additional information about follow-up was obtained from the Regional Complex Oncological Centre (RCOC. Data about patient and tumor characteristics – age, sex, site of cancer, stage, degree of differentiation and survival rates were analyzed. The overall 5-year survival rate was 36% while the disease-specific survival rate was 45%. The highest chance for survival was for upper lip (66% while the lowest was for retromolar trigone (0%. Overall survival rate depended also on the stage and grade of differentiation of the tumor. The study confirmed that oral cancer remains serious problem in terms of risk factors, delayed diagnosis, and overall survival rates.

    Spermatocytic seminoma is a rare testicular germ cell tumor of old men. Accounting for 1-4% of all seminomas, spermatocytic seminomas have distinct pathogenesis, histological features, immunohistochemical profile and comparatively benign clinical behavior which distinguishes them from other germ cell tumors, especially classic seminoma. The purposes of our study were to assess the patient demographics, pathological features and to evaluate the utility of CD 117 immunostain along with other immunohistochemical stains in distinguishing Spermatocytic seminomas from classic seminomas. All spermatocytic seminomas patients diagnosed during 1992 to 2013 at Section of Histopathology, Department of Pathology and Microbiology, Aga Khan University hospital were included. Patient characteristics, histological details and follow-up data of few patients were available. CD 117 expression was determined by immunohistochemistry. Total 16 cases of Spermatocytic seminomas were reviewed. Median age was 60 years and average tumor size was 10.4 cms. Microscopically, all of the 16 cases showed presence of edema and absence of lymphocytic infiltrate and intratubular germ cell neoplasia. Cytoplasmic glycogen was negative in all 13 cases, PLAP immunostain was negative in all 12 cases, while CD 117 was positive in all 8 cases, where applied. CD 117 is of limited utility in differentiating the spermatocytic seminoma from classic seminoma as it is expressed in significant number of spermatocytic seminomas. However, different histological features, PAS special stain and PLAP immunostain are significantly helpful in distinguishing these two entities.

    Muscle-skeletal tumors represent a challenging pathology for orthopedic surgeons worldwide. The extremely invasive character, the local destruction, the high recurrence rate, the high incidence in young patients and the unfavorable prognosis are all very well known. For these patients it is very important to produce an accelerated functional, social and psychological postoperative rehabilitation. We studied 121 cases of muscle-skeletal tumors which were treated in our hospital over a 5 years period. We noticed a high prevalence in males and mainly between the 2nd-3rd and 5th-7th decades of their life. At our observation, most patients were suffering in advanced stages of malignant lesions. We try to manage amputations below 5%, with a significant reduction in introducing reconstructive surgical methods as a choice of treatment (10 prostheses and 12 cases of filling with acrylic cement or bone substituent increased with internal fixation). In this way we could observe an unusual ratio between benign and malignant tumors, probably caused by the patient's lack of concern for minimal symptoms. The rural citizen's addressability towards the medical system is alarmingly low, due to the big gap existing from diagnosis to treatment. There is still an hard effort to develop better reconstructive techniques for the treatment of muscle-skeletal tumors and more studies must be made in order to achieve this goal.

    The incidence of primary systemic vasculitides varies among different geographic regions and ethnic origins. The aim of this study was to examine the incidence rates of vasculitides in the Jerusalem Jewish population, and to examine possible trends in incidence rates over a 20-year period. The clinical databases of inpatients at the 2 medical centers in Jerusalem were searched for patients with vasculitis diagnosed between 1990-2009. Individual records were then reviewed by one of the authors. The significance of trends in incidence rates throughout the study period was evaluated by Pearson correlation coefficient. The average annual incidence rate of polyarteritis nodosa was 3.6/million adults (95% CI 1.6-4.7). Incidence rates did not change significantly during this period (r = 0.39, p = 0.088). The incidence of granulomatosis with polyangiitis (GPA) was 4.1 (2.2-5.9) for the whole period, during which it increased significantly (r = 0.53, p Jerusalem are in the lower range of global incidence rates. While GPA and MPA incidence are increasing, GCA incidence is decreasing.

    Despite close genetic and phenotypic relationship of Candida dubliniensis with Candida albicans, its role in human disease is mostly restricted to oral colonisation, particularly among HIV-infected patients. The prevalence of C. dubliniensis in association with other disease conditions has been infrequently reported. In this study, we present data on the prevalence of C. dubliniensis among yeast species isolated from cancer patients over a 5-year period. A total of 1445 yeast isolates recovered from respiratory specimens, blood, urine and oral swabs were analysed. Candida dubliniensis isolates were provisionally identified by phenotypic methods and their identity was further confirmed by species-specific amplification and/or sequencing of internally transcribed spacer region of rDNA. Antifungal susceptibility for fluconazole was determined by Etest. The number of isolates identified as C. dubliniensis, C. albicans and other yeast species were 71 (4.9%), 862 (59.6%) and 512 (35%) respectively. All the C. dubliniensis isolates originated from respiratory (5.9%) or oral (3.2%) specimens with an overall prevalence of 4.9%, and were found to be susceptible to fluconazole. The isolation of C. dubliniensis from respiratory or oral specimens and not from blood or urine specimens suggests that this species has preference to colonise these sites of human body.

    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.

    Lei Lei

    Full Text Available 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.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.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 between the patients

    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

    Full Text Available Statement of the Problem: Langerhans cell histiocytosis is a rare disease with unknown pathogenesis and is characterized by local or disseminated proliferation of Langerhans cells. There is no previous investigation on prevalence of oral Langerhans cell histiocytosis in Iranian population. Purpose: The purpose of this study was to assess the relative frequency of oral Langerhans cell histiocytosis in an Iranian population and to compare the data with previous reports. Materials and Method: Pathology files of Oral and Maxillofacial Pathology Department of Dental School of Shahid Beheshti University of Medical Sciences from 1992 to 2012 were searched for cases recorded as oral Langerhans cell histiocytosis. A total number of 20 cases were found and the clinical information of patients was recorded. Results: The relative frequency of oral Langerhans cell histiocytosis was 0.34% and the most common location was the posterior mandible. In addition, the mean age of patients was 27 years and there was a definite male predominance. Most lesions were localized and tooth mobility was the most common oral presentation. Conclusion: In Iranian population as in many other countries, the relative frequency of oral Langerhans cell histiocytosis is low. Moreover, tooth mobility and periodontal lesions are the frequent early signs of disease. Therefore, in patients with periodontal problems, good oral health, and no response to the treatment; Langerhans cell histiocytosis must be considered. Additionally, although most cases of oral Langerhans cell histiocytosis are localized, systemic involvement must also be considered and dental professionals have an important role in early detection of the disease.

    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.

    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 Studies published from centers across India have reported different and contradicting patterns of glomerular disease. In this retrospective study, we report our experience from a Tertiary Care Center in Northwest India. A total of 702 renal biopsies performed between 2008 and 2013 were reviewed of which 80 were excluded from the study because of having insufficient records or if the biopsies were taken from an allograft. The study included 411 males (66.1 % and 211 females (33.9% with an age range of 12-70 years (mean 30.34 ± 7.04 years. Majority of the biopsies (93.9% showed some form of glomerulonephritis (GN, either primary (79.4% or secondary glomerular disease (SGD (14.5%. Minimal change disease (MCD was the most common type of primary GN (26.5% of primary GN, followed by membranous nephropathy (MN; 18.8% and focal and segmental glomerulosclerosis (FSGS; 13.2%. Lupus nephritis (LN was the most frequent SGD (52.2% of secondary GN. Amyloidosis was found in 41.1% and diabetic glomerulosclerosis in 4.4%. LN was also the second most common diagnosis in females after MCD, seen in 19.4% of females. MCD followed by membranoproliferative GN and diffuse proliferative GN were the most common entities in individuals <20 years of age. In the 20-39 years age group, MN was the most common pathology seen. MN was again the most common pathology seen in patients aged above 40 years followed by amyloidosis and FSGS. In this study, MCD was the most common primary GN observed overall from this part of India. MN was the most common GN in individuals above 20 years of age presenting with the nephrotic syndrome. The geographical and regional differences in the pattern of GNs point to the necessity of having a central biopsy registry.

    Full Text Available PURPOSE: To identify the frequency and causes of uveitis leading to visual impairment in patients referred to the Low Vision Service - Department of Ophthalmology - UNIFESP, over a twenty years period. METHODS: In a retrospective study, medical records of 5,461 patients were reviewed. Data from the first clinical evaluation at the Low Vision Service were collected, patient's age, gender and cause of visual impairment were analyzed. Patients with uveitis had their chart reviewed for anatomical classification and clinical diagnosis. RESULTS: The mean age of the patients referred to the Low Vision Service was 42.86 years and the mean age of patients with uveitis diagnosis was 25.51 years. Retinal disorders were the most common cause of visual impairment (N=2,835 patients; 51.9% followed by uveitis (862 patients, 15.7%. Uveitis was posterior in 792 patients (91.9% of uveitis and toxoplasmosis was the most common diagnosis (765 patients, 88.7%. CONCLUSIONS: In our study, uveitis represents the second cause of visual impairment in patients referred for visual rehabilitation and toxoplasmic retinochoroiditis was the most common clinical diagnosis. It affects a young working age population with a relevant social and economic impact, but the early diagnosis and treatment can improve the quality of life of these patients.

  9. How Much Progress Do Children in Shanghai Make Over One Academic Year? Evidence From PISA

    2016-11-01

    Full Text Available Since its entry into the Programme for International Student Assessment (PISA in 2009, the Chinese province of Shanghai has been the top-performing economy within these international rankings. Many have interpreted this as demonstrating how Shanghai has a “world class” education system, the most effective teaching methods, and the best schools. This article questions such interpretations of the PISA results. Specifically, we argue that statements about school and school system quality require information on the progress that children make during their time at school, which the PISA rankings do not provide (at least not directly. Our empirical analysis then uses a “fuzzy” regression discontinuity design approach to demonstrate how a rather different perspective of Shanghai’s performance in PISA emerges once pupils’ academic progress over one particular school year is considered. Our key finding is that the first year of upper secondary school in Shanghai adds essentially no value (on average to children’s PISA reading, science, and mathematics test scores.

    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

    While advanced diagnostic imaging is a large contributor to the growth in health care costs, direct-access to physical therapy is associated with decreased rates of diagnostic imaging. No study has systematically evaluated with evidence-based criteria the appropriateness of advanced diagnostic imaging, including magnetic resonance imaging (MRI), when ordered by physical therapists. The primary purpose of this study was to describe the appropriateness of magnetic resonance imaging (MRI) or magnetic resonance arthrogram (MRA) exams ordered by physical therapists in a direct-access sports physical therapy clinic. Retrospective observational study of practice. Greater than 80% of advanced diagnostic imaging orders would have an American College of Radiology (ACR) Appropriateness Criteria rating of greater than 6, indicating an imaging order that is usually appropriate. A 2-year retrospective analysis identified 108 MRI/MRA examination orders from four physical therapists. A board-certified radiologist determined the appropriateness of each order based on ACR appropriateness criteria. The principal investigator and co-investigator radiologist assessed agreement between the clinical diagnosis and MRI/surgical findings. Knee (31%) and shoulder (25%) injuries were the most common. Overall, 55% of injuries were acute. The mean ACR rating was 7.7; scores from six to nine have been considered appropriate orders and higher ratings are better. The percentage of orders complying with ACR appropriateness criteria was 83.2%. Physical therapist's clinical diagnosis was confirmed by MRI/MRA findings in 64.8% of cases and was confirmed by surgical findings in 90% of cases. Physical therapists providing musculoskeletal primary care in a direct-access sports physical therapy clinic appropriately ordered advanced diagnostic imaging in over 80% of cases. Future research should prospectively compare physical therapist appropriateness and utilization to other groups of providers and

    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

    1999-07-01

    Forty-one first semester master level nursing students from three Canadian universities participated in this descriptive correlational study to identify the influence of achievement motivation and anxiety on their academic success. Academic success was determined by their first semester grade point average (GPA). Participants had high achieving tendencies (M = 73.5) and academic ability (M = 81.9), supporting Atkinson's (1957, 1964) achievement motivation theory which was used as the framework. While state anxiety was negatively correlated, trait anxiety was the only valid predictor of academic success. Academic ability and inherent anxiety had a greater potential for predicting students who would succeed, which has implications for nurse educators, administrators and researchers. However, the need to assess both cognitive and non-cognitive variables to determine master level nursing students' ability to succeed is recommended.

    Background There are no clear guidelines on implant removal. Few have assessed the long-term outcomes of patients with implants left in-situ, or removed. Therefore, removal of implants after fracture fixation remains controversial. Methods In this retrospective study, we reviewed 53 patients with implant for fracture fixation in-situ for more than 3 years. All patients were younger than 60 years. Quality of life of each patient was assessed with the Chinese (Hong Kong)validated Short Form-36 and the pain was assessed with visual analogue scale (VAS). All patients were clinically examined and plain radiographs were taken. Results The total SF-36 score of the patients was not statistically different from the Hong Kong norm (P >0.05). Mean score of VAS was 2.08. Thirty-three patients (62.3%) reported limited range of movement, 9 patients (17%) complained of cosmetic problems, and 10 patients (18.9%) complained of weakness. Clinically, 82.6% of patients had no scarring,84.7% of patients had full range of movement and all had no tenderness on assessment. Radiologically, no abnormality was detected except for one patient with known avascular necrosis of the femoral head after screw fixation. Conclusion As most patients were clinically and radiologically normal with quality of life scores comparable to the norm,removal of implants is not advisable as a routine practice.

    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.

    The objectives of the study are to study the clinical features of myasthenia gravis in southern China. A retrospective study was carried out on all patients who were diagnosed with myasthenia gravis at the First Affiliated Hospital of Sun Yat-sen University during 1987-2009. Of the 2,154 myasthenia gravis patients, the gender ratio (male:female) was 1:1.15. The median age at onset was 18 years. There was a single peak distribution of age at onset, and 44.8 % were children (≤ 14 years) at first onset. 1,766 patients (82.0 %) only had ocular symptoms at onset. 1,451 patients (67.4 %) were classified as Osserman grade I. 250 unselected patients received anti-acetylcholine receptor antibodies test, in which only 51.2 % were positive. Computed tomography scan/magnetic resonance Imaging of chest were done in 1,354 patients, of which 899 patients (66.4 %) had thymic hyperplasia and 201(14.8 %) had thymoma. There were 150 patients (7.0 %) with myasthenia gravis combined with other autoimmune diseases, in which hyperthyroidism was most common (84 %). 189 (8.8 %) patients experienced 267 episodes of crisis. The rate of family myasthenia gravis was 1.6 % (35/2,154). In conclusion, the clinical features and demography of myasthenia gravis patients in this study are significantly different from prior studies on other regions and ethnic groups.

    This progress report reviews the University of Wyoming`s approach to implementing the DOE Traineeship Program, and briefly describes the research performed by the DOE/EPSCoR Trainees during the academic year, 1992--1993. These brief descriptions of individual research projects demonstrate the wide scope of energy-related research that the DOE-EPSCoR Traineeships have initiated in Wyoming. The availability of this funding has encouraged many talented students to continue their education in fields of interest to DOE. These additional bright, energetic graduate students have improved the educational atmosphere for everyone. The visibility of the DOE program has sharpened the focus of the science and engineering departments on the energy-related research of importance to Wyoming and DOE. The impact of the DOE Traineeships in Wyoming has been substantial and very positive. It has not only increased the number of students studying in energy-related disciplines, but has also increased the quality of their graduate research. The program has also increased the visibility of DOE in Wyoming and has helped focus attention on the energy and environmental graduate education which is so essential to the University and the State.

    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.

    To examine the impact and additive effect of phonology and rapid naming deficits on reading, spelling and mathematics achievement in a group of very preterm children at 8 years of age. All surviving children with a gestational age less than 30 weeks, admitted to the neonatal intensive care unit at Royal Prince Alfred Hospital, in 1994 and 1995, were prospectively enrolled in developmental follow-up. Children with a neurosensory disability or a low intelligence score (FSIQacademic achievement were administered to a sample of 63 children. Twenty-four (38.1%) children showed low achievement in reading, spelling or mathematics. Of these, 18 (75%) children showed low achievement in reading. Reading achievement was significantly correlated to phonological awareness, rapid naming and expressive vocabulary. Children with phonological awareness and rapid naming deficits showed significantly more delay in reading than children without such deficits. Children who had rapid naming deficits were more likely to show multiple skill delays. Rapid naming showed significant, though modest correlations with immaturity and illness variables. Maternal education was significantly associated with achievement. Phonological awareness does predict reading performance in very preterm children. Rapid naming appears to be related to complex multiple academic delays, and may reflect a neurological timing or efficiency factor with effects independent of intelligence and significantly influenced by immaturity and illness.

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

    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.

    Full Text Available This three-year longitudinal study explored the effects of parental attachment and initial college adjustment on students' perception of parental involvement in academic functioning as well as contributions of several parenting dimensions to academic, emotional and social adjustments after three years of college. A total of 171 Croatian college students (118 females completed questionnaires related to their parental attachment, parental involvement in academic functioning, and adjustment to college. Data were analyzed by hierarchical regression analysis. Results suggested that parental involvement in academic functioning in the second year is more related to the quality of attachment to parents than to the initial adjustment to college. While attachment was a significant predictor of only emotional adjustment, parental support in academic functioning predicted academic and social adjustment to college after three years of college. Results suggest that various factors related to parenting continue to play an important role in different aspects of students' adjustment to college.

    Background An association between serum calcium level and risk of metabolic syndrome (MetS) has been suggested in cross-sectional studies. This study aimed to evaluate the association between baseline serum calcium level and risk of incident MetS in a longitudinal study. Methods We conducted a retrospective longitudinal study of 12,706 participants without MetS who participated in a health screening program, had normal range serum calcium level at baseline (mean age, 51 years), and were followed up for 4.3 years (18,925 person-years). The risk of developing MetS was analyzed according to the baseline serum calcium levels. Results A total of 3,448 incident cases (27.1%) of MetS developed during the follow-up period. The hazard ratio (HR) for incident MetS did not increase with increasing tertile of serum calcium level in an age- and sex-matched model (P for trend=0.915). The HRs (95% confidence interval [CI]) for incident MetS comparing the second and the third tertiles to the first tertile of baseline serum calcium level were 0.91 (95% CI, 0.84 to 0.99) and 0.85 (95% CI, 0.78 to 0.92) in a fully adjusted model, respectively (P for trend=0.001). A decreased risk of incident MetS in higher tertiles of serum calcium level was observed in subjects with central obesity and/or a metabolically unhealthy state at baseline. Conclusion There was no positive correlation between baseline serum calcium levels and incident risk of MetS in this longitudinal study. There was an association between higher serum calcium levels and decreased incident MetS in individuals with central obesity or two components of MetS at baseline. PMID:28029017

    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: Adverse Cutaneous Drug Reactions (ACDRs account for 3% of all hospitalizations. The spectrum of drug reactions can be varied from mild to life threatening forms. Since the diagnosis of ACDR is purely clinical, early and prompt identification and withdrawal of drug (s is life saving for the patient. Aim and Objectives: To study the epidemiological and common clinical patterns and drugs causing ACDRs in tertiary care hospital of Goa Medical College, Goa over a 6 year period. Material and Methods:This was a retrospective study conducted over a period of 6 years. The medical records were analyzed for demographic profiles, morphology of drug eruptions, common groups of drugs involved, presence of co-morbid factors, systemic and mucosal involvement, common haematological abnormalities encountered, time interval between drug intake and onset of rash and mortality. Results: Our study population had 256 patients and the age group of 21-40 years was commonly affected. Maculopapular rash followed by angioedema were the commonest morphology of drug rash patterns encountered in our study. The time interval between consumption of drugs and onset of ACDR varied with interval of 1-7 days being the commonest group in having 158 (61.7% patients. Antibiotics followed by anticonvulsants and antiretrovirals were the commonest groups of drugs causing ACDR. We found that significant proportion of our patients had haematological, renal and hepatic system involvement. Conclusion: Early identification and withdrawal of the culprit drug remains the cornerstone in prevention of mortalities in ACDRs. A prior knowledge about the reaction patterns and common offending drugs in the population by the treating physician cannot be overemphasized.

    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 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.

    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.

    School engagement is an important theoretical and practical cornerstone to the promotion of academic accomplishments. This article used a tripartite-behavioral, emotional, and cognitive-model of school engagement to assess the relationship between school engagement and academic success among high school students, and to determine whether a reciprocal relationship exists between these constructs. Data were derived from 710 youth (69% female) who took part in Waves 6 through 8 (Grades 10 through 12) of the 4-H study of positive youth development. Longitudinal confirmatory factor analyses confirmed the invariance of the tripartite model of school engagement. Results of a structural equation model showed that the components of school engagement and academic achievement were mutually predictive and that these predictions varied from grade to grade. Future possibilities for evaluating the relationship between school engagement and academic achievement, as well as the implications for educational policy and practice, are discussed.

    This study aimed to examine differences in socio-demographics and health behaviour between Belgian first year university students who attended all final course exams and those who did not. Secondly, this study aimed to identify weight and health behaviour related correlates of academic performance in those students who attended all course exams. Anthropometrics of 101 first year university students were measured at both the beginning of the first (T1) and second (T2) semester of the academic year. An on-line health behaviour questionnaire was filled out at T2. As a measure of academic performance student end-of-year Grade Point Averages (GPA) were obtained from the university's registration office. Independent samples t-tests and chi2-tests were executed to compare students who attended all course exams during the first year of university and students who did not carry through. Uni- and multivariate linear regression analyses were conducted to identify correlates of academic performance in students who attended all course exams during the first year of university. Students who did not attend all course exams were predominantly male, showed higher increases in waist circumference during the first semester and consumed more French fries than those who attended all final course exams. Being male, lower secondary school grades, increases in weight, Body Mass Index and waist circumference over the first semester, more gaming on weekdays, being on a diet, eating at the student restaurant more frequently, higher soda and French fries consumption, and higher frequency of alcohol use predicted lower GPA's in first year university students. When controlled for each other, being on a diet and higher frequency of alcohol use remained significant in the multivariate regression model, with frequency of alcohol use being the strongest correlate of GPA. This study, conducted in Belgian first year university students, showed that academic performance is associated with a wide range

    Open globe injury (OGI) is a common cause of unilateral visual loss in all age groups. To describe and identify clinical characteristics, prognostic factors and visual outcome in a group of patients with OGI in southern Israel. We conducted a retrospective review of all cases of OGI examined in the ophthalmology department at Soroka University Medical Center, Beer Sheva, Israel, from 1996 to 2005. A total of 118 eyes with OGI were detected and analyzed statistically. We recorded demographic data, cause of injury, initial visual acuity (VA), associated globe morbidity and injuries, Ocular Trauma Score (OTS), surgical procedures, postoperative complications, and final VA. The mean age of the study group was 36.1 years and included 84% males. The median follow-up was 13.3 months (range 6-66 months). The annual incidence of open globe injuries was 3.1 cases/100,000. In 84 cases (71%) the mechanism of open eye injury was laceration. Most of the injuries were work related (45%). Bilateral injury was observed in two patients. An intraocular foreign body was observed in 45 eyes (38%). Primary surgical repair was performed in 114 eyes. Six patients (5.1%) had complications with posttraumatic endophthalmitis and 12 patients (10.1%) underwent evisceration or enucleation. Clinical signs associated with poor visual outcomes included reduced initial VA, eyelid injury, and retinal detachment at presentation. In our study population the most important prognostic factors in open globe injury were initial VA, eyelid injury and retinal detachment.

    Full Text Available Abstract Background Tetanus is still a major health problem in developing countries and it is associated with a high morbidity and mortality rate. There is paucity of published data regarding the management of tetanus in Tanzania, especially the study area. This study was conducted to describe our own experiences with tetanus outlining the clinical characteristics and treatment outcome of tetanus patients in our environment and to identify predictors of outcome of these patients. Methods This was a ten-year period retrospective study of patients who presented with a clinical diagnosis of tetanus at Bugando Medical Centre between January 2001 and December 2010. Data was analyzed using SPSS computer software system. Results A total of 102 patients were studied. The male to female ratio was 11.8: 1. The majority of patients (74.5% were aged Conclusion Tetanus remains a major public health problem in our centre and still carries unacceptably high morbidity and mortality despite the available advanced management facilities including ICU care. Young adult males are commonly affected. The incidence of tetanus can be reduced significantly by an effective immunization program and proper wound management of the patients. Early recognition, intense support and prompt treatment improves morbidity and mortality of patients diagnosed with tetanus.

    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.

    Tea tree oil use is increasing, with considerable interest in it being a 'natural' antimicrobial. It is found in many commercially available skin and hair care products in Australia. We retrospectively reviewed our patch test data at the Skin and Cancer Foundation Victoria over a 4.5-year period and identified 41 cases of positive reactions to oxidized tea tree oil of 2320 people patch-tested, giving a prevalence of 1.8%. The tea tree oil reaction was deemed relevant to the presenting dermatitis in 17 of 41 (41%) patients. Of those with positive reactions, 27 of 41 (66%) recalled prior use of tea tree oil and eight of 41 (20%) specified prior application of neat (100%) tea tree oil. Tea tree oil allergic contact dermatitis is under-reported in the literature but is sufficiently common in Australia to warrant inclusion of tea tree oil, at a concentration of 10% in petrolatum, in standard patch-test series. Given tea tree oil from freshly opened tea tree oil products elicits no or weak reactions, oxidized tea tree oil should be used for patch testing.

    To highlight the revolving door (RD) phenomenon in an acute psychiatric ward, we retrospectively identified the patients hospitalized three or more times in a calendar year from 1/1/2009 to 31/12/2013 as RD patients (RDP). We collected sociodemographic and clinical variables of RDP and statistically analyzed the potential RD risk factors. We divided RDP into "high" and "extremely high" utilizers and evaluated the variables related to more frequent readmissions. RDP represented 5.68% of all patients and their hospitalizations (RDH) 25% of all admissions. The statistically significant risk factors for all RDH were "disability pension," "substance abuse/dependence," "mild/severe aggressiveness," and "psychiatric and social rehabilitative programs". The comparison between "high" and "extremely high" utilizers showed that "manic episodes" and "personality disorders," among the diagnoses, "familial relational conflicts" and "violence/suicidality", among the hospitalization reasons, were statistically significant risk factors for more frequent readmissions. RD phenomenon was greatly affected by severe clinical conditions with social disability.

    Background Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in the United States. Although studies have been performed on malignancy behavior in African Americans and Caucasians, scant data are present on other minority racial groups. Methods A retrospective single center study was performed where 1,860 patient charts with a diagnosis of CRC from January 1, 2004 to December 31, 2014 were reviewed. Data collected on each patient included age, gender, ethnicity, primary site and histological stage at the time of diagnosis. Survival time over the course of 5 years was documented for patients from January 1, 2004 to December 31, 2009. Comparisons were made amongst different racial groups for the above mentioned factors. Results Study population consisted of 27.09% African Americans, 65.61% Caucasians, 3.86% Hispanics, 0.54% South Asians, 1.03% Arabs, 0.54% Asians and 0.22% American Indians. Mean age of CRC presentation was found to be significantly different (P < 0.05) between the three largest racial groups: 71 years for Caucasians, 69 years for African Americans, and 61 years for Hispanics. African Americans (27.09%) and Hispanics (28.79%) presented predominantly at stage IV in comparison to other racial groups. Caucasians presented predominantly at stage III (24.84%). The rectum was the most common site of CRC across all racial groups with the exception of Asians, where sigmoid colon was the predominant site (30%). Adenocarcinoma remained the predominant cancer type in all groups. Hispanics had relatively higher incidence rate of carcinoid tumor (12.68%). Survival time analysis showed that Caucasians tend to have better survival probability over 5 years after initial diagnosis as compared to African Americans and Hispanic (P < 0.05). Conclusion There is lack of studies performed on minority racial groups in North America. Our study highlighted some important clinical differences of CRC presentation in different racial groups which are not

    To assess trends in HIV-1 incidence and risk factors for seroconversion among men who have sex with men (MSM) resident in Rome, Italy, a retrospective longitudinal cohort study was conducted over 25 years. Incidence rates and trends were modelled using Poisson regression and risk factors were assessed by multivariate Cox models. Of 1,862 HIV-1-negative individuals, 347 seroconverted during follow-up. HIV-1 incidence rates increased from 5.2/100 persons/year (p/y) in 1986 (95% confidence interval (CI): 2.3–11.5) to 9.2/00 p/y in 1992 (95% CI: 6.4–13.0), decreased to 1.3/100 p/y in 2001 and increased until 2009 (11.7/100 p/y; 95% CI: 7.4–18.6). The risk of HIV-1 seroconversion increased during the study period in younger MSM (incidence rate ratio (IRR) = 17.18; 95% CI: 9.74–30.32 in 16–32 year-olds and IRR = 5.09; 95% CI: 2.92–8.87 in 33–41 year-olds) and in those who acquired syphilis (IRR = 7.71; 95% CI: 5.00–11.88). In contrast, the risk of seroconversion decreased among highly educated MSM (IRR = 0.54; 95% CI: 0.35–0.82) and those without Italian citizenship (IRR = 0.45; 95% CI: 0.28–0.71). The HIV epidemic in MSM living in Rome continues to expand. Targeted prevention programmes against sexually transmitted infections to enhance knowledge transfer and behavioural skills are urgently required.

    Full Text Available Abstract Objective: The aim of this study was to evaluate tuberculosis control programmes of patients who applied to the Bursa Nilufer Tuberculosis Dispensary and by investigating the changes in the variables over 3 decades. Method: In this retrospective descriptive study, the records of all tuberculosis cases (1662 people treated in the last 30 years (1985-2014 at the Bursa Nilufer Tuberculosis Dispensary were examined. In the analysis, the chi-square test, the trend chi-square test and Fisher's exact test were used. Results: Males comprised 65.2% of the patients. The ages of the patients ranged from 1 to 87 years, and the mean age was 37.4 (95% CI:36.6-38.2. Among the cases, 86.7% were new and 74.1% were pulmonary tuberculosis. In the last decade, the proportion of women, the education level, the proportion of patients who had received a BCG vaccination and the proportion of active employees among women increased by a statistically significant amount, while the proportion of employees among men decreased. Clinical symptoms, such as weakness, anorexia, weight loss, and cough, decreased to a statistically significant degree. In the last decade, the mortality rate was 3.6%, a statistically significant increase compared with previous decades. Mortality was statistically significant higher among patients who were elderly, male, did not have a BCG scar or had a chronic disease. Conclusion: This study reveals the need for studies that determine the risk factors associated with tuberculosis mortality and examine the effectiveness of tuberculosis control programmes. Direct measures to address mortality risk factors can reduce the number of deaths from tuberculosis.

    The electric flash burns are a common cause of accident at workplace, especially among electricians. The aim of this study is to determine the parts of the body most often burned by the flash, to define the usual course and finally to give some simple rules of care and prevention. This is a retrospective, observational and descriptive study including all patients treated at the University Hospital of Tours for electrical flash burns between 1 January 2003 and 01 January 2013. A collection of medical and socio-economic data was achieved. We present 3 cases of patients hospitalized in our department. Thirty-three patients were included. In our series, all hospitalized patients were men. The average age was 43.2years (range 18 to 82years). In 81% of cases, the burn was due to a low voltage source, in 19% of cases to a high voltage source. It was an accident at workplace for 71% of patients, of whom 67% were electricians. The average total burned area was 9,52% (from 1.5% to 24%). The main locations included the face (86%), upper limbs (86%) and hands (86%). Medical treatment has healed 95% of patients. A surgical procedure was required in 5% of cases. A post-traumatic stress was found in 41% of patients. Outpatient treatment was performed in 36% of cases. Flash burns remain a common cause of hospitalization. Screening for hearing and eye disorders, a post-traumatic stress, as well as the prescription of early physiotherapy for burned hands are important components of their management. Following simple rules of prevention would limit their morbidity. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

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

    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."

    Consumption of oily fish more than once per week has been shown to improve cognitive outcomes in children. However, it is unknown whether similar benefits can be achieved by long-term omega-3 fatty acid supplementation. The objective was to investigate the effect of omega-3 fatty acid supplementation during the first 5 years of life on subsequent academic performance in children by conducting a secondary analysis of the CAPS (Childhood Asthma Prevention Study). A total of 616 infants with a family history of asthma were randomised to receive tuna fish oil (high in long-chain omega-3 fatty acids, active) or Sunola oil (low in omega-3 fatty acids, control) from the time breastfeeding ceased or at the age of 6 months until the age of 5 years. Academic performance was measured by a nationally standardised assessment of literacy and numeracy (National Assessment Program Literacy and Numeracy (NAPLAN)) in school years 3, 5, 7 and 9. Plasma omega-3 fatty acid levels were measured at regular intervals until 8 years of age. Between-group differences in test scores, adjusted for maternal age, birth weight and maternal education, were estimated using mixed-model regression. Among 239 children, there were no significant differences in NAPLAN scores between active and control groups. However, at 8 years, the proportion of omega-3 fatty acid in plasma was positively associated with the NAPLAN score (0.13 s.d. unit increase in score per 1% absolute increase in plasma omega-3 fatty acid (95% CI 0.03, 0.23)). Our findings do not support the practice of supplementing omega-3 fatty acids in the diet of young children to improve academic outcomes. Further exploration is needed to understand the association between plasma omega-3 fatty acid levels at 8 years and academic performance.

    Full Text Available Hyperglycaemia during hospital admission is common in patients who are not known to have diabetes and is associated with adverse outcomes. The risk of subsequently developing type 2 diabetes, however, is not known. We linked a national database of hospital admissions with a national register of diabetes to describe the association between admission glucose and the risk of subsequently developing type 2 diabetes.In a retrospective cohort study, patients aged 30 years or older with an emergency admission to hospital between 2004 and 2008 were included. Prevalent and incident diabetes were identified through the Scottish Care Information (SCI-Diabetes Collaboration national registry. Patients diagnosed prior to or up to 30 days after hospitalisation were defined as prevalent diabetes and were excluded. The predicted risk of developing incident type 2 diabetes during the 3 years following hospital discharge by admission glucose, age, and sex was obtained from logistic regression models. We performed separate analyses for patients aged 40 and older, and patients aged 30 to 39 years. Glucose was measured in 86,634 (71.0% patients aged 40 and older on admission to hospital. The 3-year risk of developing type 2 diabetes was 2.3% (1,952/86,512 overall, was 15 mmol/l had higher mortality than patients with a glucose of <6.1 mmol/l (hazard ratio 1.54; 95% CI 1.42-1.68 and 2.50; 95% CI 2.14-2.95, respectively in models adjusting for age and sex. Limitations of our study include that we did not have data on ethnicity or body mass index, which may have improved prediction and the results have not been validated in non-white populations or populations outside of Scotland.Plasma glucose measured during an emergency hospital admission predicts subsequent risk of developing type 2 diabetes. Mortality was also 1.5-fold higher in patients with elevated glucose levels. Our findings can be used to inform patients of their long-term risk of type 2 diabetes, and to

    Context: Discoid lupus erythematosus (DLE) and human immunodeficiency virus (HIV) are both disorders of the immune system. The pathophysiology of these diseases varies greatly as DLE is characterized by an overactive immune system that attacks normal host cells, whereas HIV is characterized by an exogenous attack on the immune system that depletes it of key cell types. Although the reason is unknown, co-occurrence of DLE and HIV is rare. Aims: The goal of this study is to determine the prevalence of co-occurrence of DLE and HIV and to determine whether patients with both DLE and HIV share any clinical feature. Subjects and Methods: The medical records of all patients seen within a single academic health center over a 20-year period were reviewed to determine the prevalence of cutaneous lupus, HIV, and co-occurrence of these conditions. The charts of patients diagnosed with both conditions were further reviewed to determine similarities between them. Results: Of the 10,719 patients diagnosed with HIV and 182 patients diagnosed with cutaneous lupus, only 2 patients were diagnosed with both conditions. Both of these patients were diagnosed with DLE several years after being diagnosed with HIV. They had an undetectable HIV viral load, normal CD4 T-cell counts, and were on antiretroviral therapy when diagnosed with DLE. Conclusion: These results confirm that co-occurrence of DLE and HIV is rare. Although our study population was small, findings from these patients suggest that in HIV-positive patients, DLE manifestations occur when their HIV disease activity is minimal.

    Female infertility is a complex issue encompassing a wide variety of diagnoses, many of which are caused or affected by adhesions. The study intended to examine the rates of successful treatment of infertile women using a protocol of manual physical therapy to address underlying adhesive disease leading to infertility. Methods • The research team designed a retrospective chart review. The study took place in a private physical therapy clinic. Participants were 1392 female patients who were treated at the clinic between the years of 2002 and 2011. They had varying diagnoses of infertility, including occluded fallopian tubes, hormonal dysfunction, and endometriosis, and some women were undergoing in vitro fertilization (IVF). Intervention • All patients underwent whole-body, patient-centered treatments that used a protocol of manual physical therapy, which focused on restoring mobility and motility to structures affecting reproductive function. Improvements demonstrated in the condition(s) causing infertility were measured by improvements in tubal patency and/or improved hormone levels or by pregnancy. Results • The results included a 60.85% rate of clearing occluded fallopian tubes, with a 56.64% rate of pregnancy in those patients. Patients with endometriosis experienced a 42.81% pregnancy rate. The success rate was 49.18% for lowering elevated levels of follicle stimulating hormone (FSH), with a 39.34% pregnancy rate in that group, and 53.57% of the women with polycystic ovarian syndrome (PCOS) achieved pregnancy. The reported pregnancy rate for patients who underwent IVF after the therapy was 56.16%. The results also suggested that the treatment was effective for patients with premature ovarian failure (POF). The manual physical therapy represented an effective, conservative treatment for women diagnosed as infertile due to mechanical causes, independent of the specific etiology.

    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

    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

    An intervention was designed that combined physical activity with learning activities. It was based upon evidence for positive effects of moderate to vigorous physical activity (MVPA) on academic achievement. The aim of this study was to describe the program implementation and effects on academic achievement after 1 year. Second- and third-grade classes of 6 elementary schools were included in the study. The intervention group participated in physically active academic lessons and the control group in regular classroom lessons. Implementation measures were obtained and the children were pretested and posttested on mathematics and reading. Teacher observations and self-reports indicated that the lessons were implemented as planned. Classroom observations showed that children's on-task behavior during the lessons was above 70%. On the basis of heart rate measures, on average 64% of the lesson time was spent in MVPA. Posttest mathematics and reading scores of third-grade children who participated in the intervention were significantly higher in comparison with control children. Posttest mathematics scores of second-grade children in the intervention condition were significantly lower in comparison with control children. The intervention program was successfully implemented and the lessons contributed to the academic outcomes of third-grade children. © 2015, American School Health Association.

    Full Text Available Abstract Background Big-fish-little-pond effect (BFLPE research has demonstrated that students in high-ability environments have lower academic self-concepts than equally able students in low-ability settings. Research has shown low academic self-concepts to be associated with negative educational outcomes. Social comparison processes have been implicated as fundamental to the BFLPE. Methods Twenty first-year students in an Australian medical school completed a survey that included academic self-concept and social comparison measures, before and after their first written assessments. Focus groups were also conducted with a separate group of students to explore students' perceptions of competence, the medical school environment, and social comparison processes. Results The quantitative study did not reveal any changes in academic self-concept or self-evaluation. The qualitative study suggested that the attributions that students used when discussing performance were those that have been demonstrated to negatively affect self-concept. Students reported that the environment was slightly competitive and they used social comparison to evaluate their performance. Conclusions Although the BFLPE was not evident in the quantitative study, results from the qualitative study suggest that the BFLPE might be operating In that students were using attributions that are associated with lower self-concepts, the environment was slightly competitive, and social comparisons were used for evaluation.

    To assess academic attainment and special educational needs (SEN) in extremely preterm children in middle childhood. Of 307 extremely preterm (special school. In mainstream schools, 105 (57%) extremely preterm children had SEN (OR 10; 6 to 18) and 103 (55%) required SEN resource provision (OR 10; 6 to 18). Teachers rated 50% of extremely preterm children as having below average attainment compared with 5% of classmates (OR 18; 8 to 41). Extremely preterm children who entered compulsory education an academic year early due to preterm birth had similar academic attainment but required more SEN support (OR 2; 1.0 to 3.6). Extremely preterm survivors remain at high risk for learning impairments and poor academic attainment in middle childhood. A significant proportion require full-time specialist education and over half of those attending mainstream schools require additional health or educational resources to access the national curriculum. The prevalence and impact of SEN are likely to increase as these children approach the transition to secondary school.

    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

Data were collected from the data archive, cephalograms, and casts, including pretreatment (T0) and posttreatment (T1) data, as well as long-term follow-up data collected approximately 25 years after treatment (T2). Each patient was assigned to a success or a failure group. Data were analyzed based on time (T0, T1, T2), deviations from normal (Class I), and prognathism types (true mandibular prognathism, maxillary retrognathism, combined pro- and retrognathism). Compared to Class I normal values, the data obtained in both groups yielded 11 significant parameters. The success group showed values closer to normal at all times (T0, T1, T2) and vertical parameters decreased from T0 to T2. The failure group showed higher values for vertical and horizontal mandibular growth, as well as dentally more protrusion of the lower anterior teeth and more negative overjet at all times. In adittion, total gonial and upper gonial angle were higher at T0 and T1. A prognostic score-yet to be evaluated in clinical practice-was developed from the results. The failure group showed greater amounts of horizontal development during the years between T1 and T2. Treatment of true mandibular prognathism achieved better outcomes in female patients. Cases of maxillary retrognathism were treated very successfully without gender difference. Failure was clearly more prevalent, again without gender difference, among the patients with combined mandibular prognathism and maxillary retrognathism. Crossbite situations were observed in 44% of cases at T0. Even though this finding had been resolved by T1, it relapsed in 16% of the cases by T2. The failure rate increased in cases of

    Full Text Available Abstract Background Many school-aged children suffer physical and mental impairments which can adversely affect their development and result in significant morbidity. A high proportion of children in western countries attend pre-school, and it is likely that the preschool environment influences the prevalence and severity of these impairments. Currently there is insufficient data available on the prevalence of these impairments and their causal associations. The influence that location of a pre-school and the duration of preschool attendance have on the prevalence of these impairments is not known. Methods In a retrospective survey spanning six years (1997–2002 we reviewed the records of 6,230 preschool children who had undergone routine school entry assessments. These children had been assessed utilising a modified manual of the "Bavarian Model" for school entry examinations. This model outlines specific criteria for impairments of motor, cognitive, behavioural and psychosocial functioning. Prevalence rates for physical and behavioural impairments were based on the results of these assessments. The relationship between the prevalence of impairments and the duration of preschool attendance and the location of the preschool attended was estimated utilizing logistic regression models. Results We found that 20.7% of children met the criteria for at least one type of impairment. Highest prevalence rates (11.5% were seen for speech impairments and lowest (3.5% for arithmetic impairments. Boys were disproportionately over represented, with 25.5% meeting the criteria for impairment, compared to 13.0% for girls. Children who had attended preschool for less than one year demonstrated higher rates of impairment (up to 19.1% for difficulties with memory, concentration or perseverance compared to those who had attended for a longer duration (up to 11.6% for difficulties with pronouncation. Children attending preschool in an urban location had slightly

    Although the evidence in support of the variability of students' learning strategies has expanded in recent years, less is known about the explanatory base of these individual differences in terms of the joint influences of personal and contextual characteristics. Previous studies have often investigated how student learning is associated with either personal or contextual factors. This study takes an integrative research perspective into account and examines the joint effects of personality, academic motivation, and teaching strategies on students' learning strategies in a same educational context in first-year higher education. In this study, 1,126 undergraduate students and 90 lecturers from eight professional bachelor programmes in a university college participated. Self-report measures were used to measure students' personality, academic motivation, and learning strategies. Students' processing and regulation strategies are mapped using the Inventory of Learning Styles. Key characteristics of more content-focused versus learning-focused teaching strategies were measured. Multivariate multi-level analysis was used to take the nested data structure and interrelatedness of learning strategies into account. Different personality traits (openness, conscientiousness, and neuroticism) and academic motivation (amotivation, autonomous, and controlled motivation) were found to be independently associated with student learning strategies. Besides these student characteristics, also teaching strategies were found to be directly associated with learning strategies. The study makes clear that the impact of teaching strategies on learning strategies in first-year higher education cannot be overlooked nor overinterpreted, due to the importance of students' personality and academic motivation which also partly explain why students learn the way they do. © 2013 The British Psychological Society.

    Full Text Available Introduction: Students pursuing a bachelor’s degree in the Vocational Teacher Education program find that good writing skills are a prerequisite to complete their education. As educators in this program, we experience that many students struggle to master the requirements for academic writing in higher education. For this reason, two teachers from the Vocational Teacher Education bachelor’s degree program in Trondheim undertook a study with the purpose of exploring how first-year students experienced an introductory course in academic writing and different forms of feedback on assignments (written, oral, and digital.Theory: The study relies mainly on Illeris’s Learning Theory.Method: Data collection is based on 24 reflection logs of 12 first-year students during 2014–2015. The analysis is based on Lindseth and Norberg’s phenomenological–hermeneutical method.Result: The findings of the study show that students experience the introductory course in academic writing as absolutely necessary and of great importance for the development of their writing competence. Specifically, responses written directly in the text in addition to a summary are forms of feedback students perceive as important and helpful. Along with oral responses, digital responses are central for developing confidence and motivation to continue working.Conclusion: First-year students express insecurity and vulnerability in regard to the writing process. They experience the writing course as essential and see aspects of written, oral, and digital guidance as important to the process of completing academic assignments in Vocational Teacher Education. Written feedback is perceived as absolutely necessary.

    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

    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

    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.

    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.

    We examined the extent to which retrospective proxy reports of well-being mirror participant self-reports at 12-24 months before death and how proxy reports of well-being change over the last year of life. We also explored the role of sociodemographic, cognitive, and health factors of both participants and proxies in moderating such associations. We used retrospective proxy ratings obtained in the German Socio-Economic Panel Study (N = 164; age at death = 19-99 years). Results revealed moderate agreement between self- and proxy reports (r = .42), but proxies, on average, overestimated participants' life satisfaction by two thirds of a scale point on a 0-10 scale (or 0.4 SD). Discrepancies were particularly pronounced when proxies themselves reported low life satisfaction. Over the last year of life, participants were viewed to have experienced declines in life satisfaction (-0.54 SD). Declines were stronger for ill participants and proxies who reported low life satisfaction. Results qualify theoretical expectations and empirical results based on self-report data that are typically available 1 or 2 years before death. We discuss that retrospective proxy reports in panel surveys can be used as a hypothesis-generating tool to gather insights into late life. © The Author 2013.

    Introduction: All medical schools in Saudi Arabia have English as the primary official medium of instruction. Most of the high school education, however, is delivered in Arabic and hence the transition to an English based learning environment tends to be difficult for some students. Our study aims to correlate English language proficiency with academic performance among medical students in their preparatory year. Methods: A cross-sectional study design was used. Test scores of 103 preparatory year students (54 female and 49 male) were analyzed after the students completed an English language course and medical introductory course in their preparatory year. The total score obtained in the English course assessment was compared to each component of the medical content assessment. Results: A significantly positive correlation (Spearman's Rho, at 0.01 levels) was seen between the scores of the English exam and the written exam (P English exam score was not obtained for the other components of the medical assessment, namely; student assignments, presentations and portfolios. Conclusion: English language proficiency is an important factor in determining academic proficiency of medical students in our college at the preparatory year level. PMID:26629471

    The etiology of delirium in intensive care units (ICU) is usually multi-factorial. There is common "myth" that lunar phases affect human body especially human brains (and minds). In the absence of any pre-existing studies in ICU patients, the current retrospective study was planned to investigate whether lunar phases play any role in ICU delirium by assessing if lunar phases correlate with prevalence of ICU delirium as judged by the corresponding consumptions of rescue anti-psychotics used for delirium in ICU. After institutional review board approval with waived consent, the daily census of ICU patients from the administrative records was accessed at an academic university's Non-Cancer Hospital in a Metropolitan City of United States. Thereafter, the ICU pharmacy's electronic database was accessed to obtain data on the use of haloperidol and quetiapine over the two time periods for patients aged 18 years or above. Subsequently the data was analyzed for whether the consumption of haloperidol or quetiapine followed any trends corresponding to the lunar phase cycles. A total of 5382 pharmacy records of haloperidol equivalent administrations were analyzed for this study. The cumulative prevalence of incidents of haloperidol equivalent administrations peaked around the full moon period and troughed around the new moon period. As compared to male patients, female patients followed much more uniform trends of haloperidol equivalent administrations' incidents which peaked around the full moon period and troughed around the new moon period. Further sub-analysis of 70-lunar cycles across the various solar months of the total 68-month study period revealed that haloperidol equivalent administrations' incidents peaked around the full moon periods during the months of November-December and around the new moon periods during the month of July which all are interestingly the major holiday months (a potential confounding factor) in the United States.

    2011-01-01

    Increasingly, it is being recognised in higher and medical education that learners should be adequately prepared for the unpredictable nature of professional practice. Several generic or transferable skills or capabilities (e.g., communication, information handling) that will enable graduates to function in an ever-changing professional world have been identified. Using a validated inventory comprising six categories of transferable skills, three cohorts of incoming male and female medical students at a Gulf university documented their level of practice and confidence for 31 skills. The exercise was repeated a year later. New medical students identified computer and organisational skills and the ability to manage their learning as strengths, but scores for technical and numeracy, information handling and presentation and communication skills suggested that learners generally required guidance. A year later, despite considerable self-reported information handling and communication skills development, learners generally did not consider themselves self-sufficient. A significant gender difference emerged, with incoming males reporting less experience and confidence in many skills. This gap was reduced but did not disappear over the first academic year. An audit such as this may be useful for identifying individual skills levels as well as providing insight into shortcomings in the academic programme in terms of opportunities for transferable skills development.

    Abstract Although randomized controlled studies reported an incidence of anesthesia awareness with recall ∼1 to 2 per 1000 (0.1–0.2%), recent data from the NAP5 study showed an incidence of only 1:19,600. Although in a prospective study many tools for anesthesia awareness detection can be used, a retrospective analysis requires a careful collection of information. The aim of the study was to evaluate the incidence of anesthesia awareness with recall in a cohort of cancer patients through a mu...

    Computed tomography (CT) has been used routinely at the Department of Forensic Medicine, University of Copenhagen since 2002. A retrospective study was performed in order to correlate CT-scan based diagnoses of cranial and cerebral lesions with macroscopic autopsy diagnoses in 56 cases. The CT...... of the anterior, medial and posterior cranial fossae was 20%, 52% and 60%, respectively. Fractures involving bilateral bones were diagnosed correctly more frequently. The diagnostic agreement regarding brain injuries varied from 0% to 79%. Both the autopsy-reports and CT-scan descriptions need to be standardized...

    The youngest children in an academic year are reported to be educationally disadvantaged and overrepresented in referrals to clinical services. In this study we investigate for the first time whether these disadvantages are indicative of a mismatch between language competence at school entry and the academic demands of the classroom. We recruited a population sample of 7,267 children aged 4 years 9 months to 5 years 10 months attending state-maintained reception classrooms in Surrey, England. Teacher ratings on the Children's Communication Checklist-Short (CCC-S), a measure of language competence, the Strengths and Difficulties Questionnaire-Total Difficulties Score (SDQ), a measure of behavioural problems, and the Early Years Foundation Stage Profile (EYFSP), a measure of academic attainment, were obtained at the end of the reception year. The youngest children were rated by teachers as having more language deficits, behaviour problems, and poorer academic progress at the end of the school year. Language deficits were highly associated with behaviour problems; adjusted odds ratio 8.70, 95% CI [7.25-10.45]. Only 4.8% of children with teacher-rated language deficits and 1.3% of those with co-occurring language and behaviour difficulties obtained a 'Good Level of Development' on the EYFSP. While age predicted unique variance in academic attainment (1%), language competence was the largest associate of academic achievement (19%). The youngest children starting school have relatively immature language and behaviour skills and many are not yet ready to meet the academic and social demands of the classroom. At a population level, developing oral language skills and/or ensuring academic targets reflect developmental capacity could substantially reduce the numbers of children requiring specialist clinical services in later years. © 2015 The Authors.

    A retrospective nested case-control study was designed to explore whether freshman year mental health status and level of adaptation are predictors of Internet addiction. The study cohort was 977 college students at a university in northwest China. In the first college year, the students' mental health status and adaptation level were assessed using the Chinese College Student Mental Health Scale (CCSMHS) and the Chinese College Student Adjustment Scale (CCSAS). In the following 1-3 years, 62 Internet-addicted subjects were identified using Young's 8-item diagnostic questionnaire. Controls were matched for demographic characteristics. Using logistic regression analysis, freshman year mental health status, including factors such as somatization, anxiety, depression and self-contempt, and freshman year adaptive problems were found to be causal factors and predictors of Internet addiction. Freshman with features of depression, learning maladaptation and dissatisfaction could be an important target-intervention population for reducing Internet addiction.

    Computed tomography (CT) has been used routinely at the Department of Forensic Medicine, University of Copenhagen since 2002. A retrospective study was performed in order to correlate CT-scan based diagnoses of cranial and cerebral lesions with macroscopic autopsy diagnoses in 56 cases. The CT-scans were performed by a forensic pathologist. They were obtained by using two different CT-scan protocols. The results showed correct skull fracture diagnoses in 34/56 cases. Fractures were diagnosed partially (9) or missed totally (13) on CT-images in 22 cases. The agreement for fracture diagnoses of the anterior, medial and posterior cranial fossae was 20%, 52% and 60%, respectively. Fractures involving bilateral bones were diagnosed correctly more frequently. The diagnostic agreement regarding brain injuries varied from 0% to 79%. Both the autopsy-reports and CT-scan descriptions need to be standardized in order to secure more exact comparisons in the future.

    A three-decade-long retrospective study of iron status in a cohort of 1250 children aged 8-36 months was carried out at the Pediatric Department at the Second University Naples. Iron status was evaluated with independent variables such as family income, weight for height, introduction of cow's milk (CM), iron supplementation and weaning. Iron deficiency (ID) is prevalent in children with low income, early introduction of CM, delayed weaning, over-weight, and in those not receiving iron supplementation (P < 0.05). The first decade (1980-1990) was marked by low family income, while early introduction of CM characterized the first two decades (1980-1990, 1990-2000) (P < 0.05). ID depends on a variety of social and dietary factors. Hematological tests should be performed early to identify children at risk for ID.

    Full Text Available Objective: Tuberculous meningitis (TBM is the most severe and lethal form of tuberculosis (TB.Bacteriologic confirmation of TBM is difficult and slow. Therefore, most patients receive ntituberculosis treatment based only on clinical and cerebrospinal fluid (CSF characteristics. Rapid diagnosis of TBM is important to decrease morbidity and mortality. The aim of the study was to demonstrate that COBAS Amplicor MTB and Rotorgene Real Time (RT PCR is a rapid method of diagnosing TBM before and after initiating anti-tuberculosis treatment. Methods: A retrospective study was conducted between December 2002 and January 2009 in 468 patients with suspected TBM. Clinical specimens were collected from different hospitals in Ankara. All specimens were evaluated by smear microscopy and culture methods with Lowenstein-Jensen (LJ and MGIT culture system. Results: Using culture results as a gold standard, the sensitivity, specificity, positive predictive values (PPV, and negative predictive values (NPV were 71.0%, 98.8%, 97.8% and 75.0%, respectively, for COBAS Amplicor MTB and 80%, 98.9%, 99.0% and 80.0%, respectively, for Rotorgene RT PCR. Statistical analysis showed no significant differences between the COBAS Amplicor MTB and Rotorgene RT PCR (p≥0.05. All isolates were susceptible to isoniazid, rifampin, streptomycin, and ethambutol with proportion method in LJ medium. All isolates were defined as LAM7-TUR by spoligotyping. Conclusion: Retrospective analysis of COBAS Amplicor MTB and Rotorgene RT PCR found that both tests are effective in rapidly diagnosing MTB using CSF. It was concluded that Rotorgene RT PCR test is more sensitive (81.0% than COBAS Amplicor MTB (71.0%. J Microbiol Infect Dis 2015;5(4: 156-161

    Barber Applewhite, Stephanie

    First-year seminars, high-impact practices, and academic self-efficacy have been identified as relevant to the successful transition process from high school to college. This study investigated the interconnections between freshman academic self-efficacy, high-impact practices, zone of proximal development and first-year seminars. This research contributed to the understandings of the significance of high-impact practices in the development of academic self-efficacy in freshman students. As colleges strive to improve retention from the freshman to sophomore years, it is useful to identify the relevance of high-impact practices within a first-year seminar on academic self-efficacy. A two-group, quasi-experimental study using a pre/post survey was conducted at a regional comprehensive university in east Texas in which 800 students were given a pre and post survey to measure academic self-efficacy. After matching for fidelity, eleven sections were identified for the control group (104 participants) and eleven sections (91 participants) were selected for the experiment group. The findings revealed that the overall gain in the mean of both groups from the pre to post survey was statistically significant. While the students in the high-impact sections reported a higher post mean on the College Academic Self-Efficacy Scale than those who did not receive high-impact instruction, the gain was not statistically significant.

    One hundred and seventy four children from the "República de Checoslovaquia" National School of the Centro Habana-Norte municipality were investigated during the 1976-1977 academic course months. The method of mail interview of parents was used. Every month the history of oropharyngeal infection and antibiotic administration was obtained, and bacteriology of pharyngeal exudates was performed. Antistreptolysin or AELO titers were determined at three-month intervals. Cardiovascular physical examinations were made and electrocardiograms obtained during the last month. 19,22% of exudates were positive for hemolytic streptococci. 46,56% of streptococcal strains isolated corresponded to the group A. Hemolytic streptococci isolation ranged between 10,4% in October, 1976 and 36,1% in April, 1977. The monthly distribution of the different serological groups of isolated hemolytic streptococci disclosed statistically significant differences. 78,26% of the 667 AELO reactions corresponded to titers of 200 or more Todd units. Average titers in the four stages of the serological study are between 382,42 and 463,92 Todd units. Significative differences between the results of bacteriology and serology and the physical state of oropharynx or the history of clinical manifestations were not evidenced. Manifestations of carditis or rheumatic fever were not found.

    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.

    "Joining a practice for the first time after training, whether in academia or the private sector is fraught with challenges and a learning curve. Postgraduate education has not sufficiently taught anyone how to manage the nuances of this new arena, or completely how to become successful. Success is not solely a function measured by reportable taxable income. Respect by colleagues, patients, partners, and staff are just as important, if not more so, and the financial attributes will be realized if the tangibles and intangibles discussed are appropriately executed in the correct environment." Although the preceding statements were made as reflecting on the first year of practice, they hold true 10 years later, and always. This article discusses what can be learned from a decade of "doing" even when having "planned well." Some concepts that have not changed are maintained throughout, some have been updated from experience, and some have been completely changed. Just remember, what you do should be dynamic and adaptable over time, but the principles, if sound from the start, never change.

    While there has been increasing emphasis and innovation nationwide in training residents in inpatient handoffs, very little is known about the practice and preparation for year-end clinic handoffs of residency outpatient continuity practices. Thus, the latter remains an identified, yet nationally unaddressed, patient safety concern. The 2014 annual Association of Program Directors in Internal Medicine (APDIM) survey included seven items for assessing the current year-end clinic handoff practices of internal medicine residency programs throughout the country. Nationwide survey. All internal medicine program directors registered with APDIM. Descriptive statistics of programs and tools used to formulate a year-end handoff in the ambulatory setting, methods for evaluating the process, patient safety and quality measures incorporated within the process, and barriers to conducting year-end handoffs. Of the 361 APDIM member programs, 214 (59%) completed the Transitions of Care Year-End Clinic Handoffs section of the survey. Only 34% of respondent programs reported having a year-end ambulatory handoff system, and 4% reported assessing residents for competency in this area. The top three barriers to developing a year-end handoff system were insufficient overlap between graduating and incoming residents, inability to schedule patients with new residents in advance, and time constraints for residents, attendings, and support staff. Most internal medicine programs do not have a year-end clinic handoff system in place. Greater attention to clinic handoffs and resident assessment of this care transition is needed.

Students so identified were offered additional workshops to address assumed knowledge and academic skills. Attendance at the workshops correlated with improved academic outcomes.

  19. Measuring the ambiguity tolerance of medical students: a cross-sectional study from the first to sixth academic years

    Science.gov (United States)

    2014-01-01

    Background Tolerance of ambiguity, or the extent to which ambiguous situations are perceived as desirable, is an important component of the attitudes and behaviors of medical students. However, few studies have compared this trait across the years of medical school. General practitioners are considered to have a higher ambiguity tolerance than specialists. We compared ambiguity tolerance between general practitioners and medical students. Methods We designed a cross-sectional study to evaluate the ambiguity tolerance of 622 medical students in the first to sixth academic years. We compared this with the ambiguity tolerance of 30 general practitioners. We used the inventory for measuring ambiguity tolerance (IMA) developed by Reis (1997), which includes three measures of ambiguity tolerance: openness to new experiences, social conflicts, and perception of insoluble problems. Results We obtained a total of 564 complete data sets (return rate 90.1%) from medical students and 29 questionnaires (return rate 96.7%) from general practitioners. In relation to the reference groups defined by Reis (1997), medical students had poor ambiguity tolerance on all three scales. No differences were found between those in the first and the sixth academic years, although we did observe gender-specific differences in ambiguity tolerance. We found no differences in ambiguity tolerance between general practitioners and medical students. Conclusions The ambiguity tolerance of the students that we assessed was below average, and appeared to be stable throughout the course of their studies. In contrast to our expectations, the general practitioners did not have a higher level of ambiguity tolerance than the students did. PMID:24405525

    Full Text Available Protein-losing enteropathy (PLE is a complication in some systemic lupus erythematosus (SLE patients that is often misdiagnosed. With this study, we provide insight into clinical characteristics, laboratory characteristics, diagnostic tests, risk factors, treatment, and prognosis of the disease.A retrospective, case-control study was performed in 44 patients with SLE-related PLE (PLE group and 88 patients with active SLE (control group admitted to our care from January 2000-January 2012. Risk factors for SLE-related PLE were examined, and we analyzed the accuracy of single and combined laboratory characteristics in discriminating SLE-related PLE from active SLE. Serum albumin and C3 levels were measured as outcome during and after treatment with corticosteroids and immunosuppressive agents.The PLE group had lower mean serum albumin and 24-hour urine protein levels, higher mean total plasma cholesterol levels, and greater frequencies of anti-SSA and SSB seropositivity compared with the control group. Anti-SSA seropositivity, hypoalbuminemia, and hypercholesterolemia were independent risk factors for SLE-related PLE. The simultaneous presence of serum albumin (<22 g/l and 24-hour urine protein (<0.8 g/24 h had high specificity, positive predictive value, negative predictive value, and positive likelihood ratio, a low negative likelihood ratio and no significant reduction in sensitivity. High dosage of glucocorticosteroid combined with cyclophosphomide were mostly prescribed for SLE-related PLE.SLE-related PLE should be considered when an SLE patient presents with generalized edema, anti-SSA antibody seropositivity, hypercholesterolemia, severe hypoalbuminemia, and low 24-hour urine protein levels. Aggressive treatment for lupus might improve prognosis.

    Alopecia areata (AA) affects anagen hair follicles, resulting in non-scarring hair loss. Since introduced by Huang et al., superficial cryotherapy has been accepted as a considerable primary therapeutic modality for AA. The aim of this study was to objectively clarify the therapeutic efficacy and safety of superficial hypothermic cryotherapy for treatment of AA. Medical records of 353 patients from 1993 to 2014 were retrospectively analyzed. According to the response to the superficial cryotherapy, patients were categorized into four groups: "marked", "partial", "poor" and "no recovery". The marked and partial recovery groups were considered as responders. The proportions of the responders among patient subgroups which were defined by various patients, disease, and treatment factors were compared. Of the patients, 60.9% were classified as responders after 3 months of superficial hypothermic cryotherapy. The proportion of the responders were higher when the treatment interval was 2 weeks or less and in the incipient disease stage, with statistical significance. No severe side-effects other than mild pain and pruritus were reported. In conclusion, superficial cryotherapy is an effective and safe therapeutic modality for AA. Especially when the treatment interval is 2 weeks or less and in the first occurrence of the disease, the therapeutic outcome is superior.

    Lower eyelid retraction can be the unfortunate result of aesthetic surgery, trauma, disease, or the aging processes. The purpose of this article is to assess whether midface lifting based on purely vertical repositioning constitutes an effective procedure for its correction. A retrospective study was carried out on 199 patients (311 eyelids) operated on between January of 2004 and January of 2014. The various causes of eyelid retraction in this population included cosmetic blepharoplasty (56.8 percent), involutional ectropion (23.1 percent), tumor resection (9.5 percent), facial nerve paralysis (8.5 percent), and trauma and related surgery (2 percent). The study was restricted exclusively to cases of moderate and severe lower eyelid retraction addressed by means of midface lifting. The mean follow-up time was 16.8 months. All of the patients were subjected to midface lifting with strengthening of the lateral canthus. A spacer graft was also used in 37.7 percent of the cases. One hundred ninety-five patients (97.9 percent) displayed objective improvement of the eyelid retraction and a marked degree of improvement both in aesthetic terms and as regards the functional disorders reported. Only four patients (2 percent) presented complications such as needing another operation. Midface lifting based on purely vertical repositioning makes it possible to recruit a considerable amount of "new" skin at the lower eyelid, thus ensuring a decrease in vertical distraction and correct recovery of the height of the external lamellar plane.

    The incidence of the human papilloma virus (HPV) has not dropped in HIV-positive patients despite the discovery of antiretroviral therapy (ART). Our goal is to assess the prevalence of HPV in HIV patients and its relationship with the epidemiological and virological characteristics of HIV patients. Retrospective cohort of 965 patients diagnosed with HIV from 1998 to 2012. We analyzed patients' demographic factors and factors related to the HPV. Of the 965 patients examined, 333 consulted a dermatologist. Of these, 52 patients had genital warts (15.6%), 43 had common warts (12.9%) and 8% had both conditions. In total, 28.5% of patients had a skin lesion caused by HPV. This is the first longitudinal observational study carried out on HIV-positive patients in the era of ART in which HPV infection is the most common skin pathology. We observed a similar trend in countries with access to ART. This study spreads awareness on the importance of preventing HPV and the difficulty of treating it in HIV-positive patients.

    Our study was designed to assess symptomatology and occurrences of narcolepsy in eastern China between 2003 and 2012. Herein we report the substantial changes in the occurrence and clinical features of narcolepsy over the last decade in China. We performed a retrospective analysis of 162 Han Chinese patients with narcolepsy at Changzheng Hospital, Shanghai, China. Clinical histories and precipitating factors were recorded, in addition to narcolepsy and H1N1 winter flu pandemic (pH1N1) occurrences at Changzheng Hospital. The occurrences also were compared between the Changzheng Hospital and the People's Hospital, Beijing, China. In our sample, narcolepsy occurred 1.73 times more frequently in men than in women. Most of the participants were children, which peaked to 91% in 2010. Excessive daytime sleepiness (EDS), disrupted nocturnal sleep, cataplexy, and weight gain were the four major symptoms. We found that 40% of patients had identifiable precipitating factors. The occurrence of narcolepsy in 2010 showed an approximate three-fold difference from the baseline levels at the Changzheng Hospital, which showed positive relationships with occurrences of pH1N1 in Shanghai and the occurrence of narcolepsy at the People's Hospital. Our findings show the interactive effects of geography and H1N1 disease in relation to narcolepsy in Han Chinese populations, and strengthen the theoretic hypothesis that immune and mental factors facilitate the onset of narcolepsy.

    Sex chromosome aneuploidies are frequently detected fortuitously in a prenatal diagnosis. Most cases of 47, XXX and 47, XYY syndromes are diagnosed in this context, and parents are thus faced with an unexpected situation. The objective of the present study was to characterize a French cohort of prenatally diagnosed cases of 47, XXX and 47, XYY and to evaluate the termination of pregnancy (TOP) rate before and after France's implementation of multidisciplinary centres for prenatal diagnosis in 1997. This retrospective study identified respectively 291 and 175 cases of prenatally diagnosed 47, XXX and 47, XYY between 1976 and 2012. For each case, the indication, maternal age, karyotype and outcome were recorded. Most diagnoses of the two conditions were fortuitous. The occurrence of 47, XXX was associated with advanced maternal age. The overall TOP rate was higher for 47, XXX (22.9%) than for 47, XYY (14.6%), although this difference was not statistically significant. However, the TOP rates fell significantly after 1997 (from 41.1% to 11.8% for 47, XXX and from 25.8% to 6.7% for 47, XYY). The TOP rates after prenatal diagnoses of 47, XXX and 47, XYY fell significantly after 1997, following France's implementation of multidisciplinary centres for prenatal diagnosis. © 2016 John Wiley & Sons, Ltd. © 2016 John Wiley & Sons, Ltd.

    Reporting and analysing the data on medication errors (MEs) is important and contributes to a better understanding of the error-prone environment. This study aims to examine the characteristics of errors submitted to the National Medication Error Reporting System (MERS) in Malaysia. A retrospective review of reports received from 1 January 2009 to 31 December 2012 was undertaken. Descriptive statistics method was applied. A total of 17,357 MEs reported were reviewed. The majority of errors were from public-funded hospitals. Near misses were classified in 86.3 % of the errors. The majority of errors (98.1 %) had no harmful effects on the patients. Prescribing contributed to more than three-quarters of the overall errors (76.1 %). Pharmacists detected and reported the majority of errors (92.1 %). Cases of erroneous dosage or strength of medicine (30.75 %) were the leading type of error, whilst cardiovascular (25.4 %) was the most common category of drug found. MERS provides rich information on the characteristics of reported MEs. Low contribution to reporting from healthcare facilities other than government hospitals and non-pharmacists requires further investigation. Thus, a feasible approach to promote MERS among healthcare providers in both public and private sectors needs to be formulated and strengthened. Preventive measures to minimise MEs should be directed to improve prescribing competency among the fallible prescribers identified.

    Data from 19,950 women were retrospectively analysed to determine the effect of chromosomal polymorphisms on female infertility and pregnancy outcome; fertile women were used as controls. Frequency of chromosomal polymorphisms and adverse pregnancy outcomes were compared between groups. A significantly higher incidence of chromosomal polymorphisms was found in total infertile patients, and patients with tubal infertility, ovulatory dysfunction, cervical and uterine abnormalities, and unexplained infertility compared with controls (5.53% [P Infertile women had a higher incidence of 9qh+ and inv(9) compared with controls (P chromosomal polymorphisms on female infertility (adjusted OR 1.662, 95% CI 1.551 to 1.796, P infertility groups, miscarriage rates were higher in women with chromosomal polymorphisms than in women with normal chromosomes (4.95% versus 0.96%, P = 0.001 and 6.17% versus 1.08%, P Chromosomal polymorphisms adversely affected spontaneous miscarriage rates (adjusted OR 1.625, 95% CI 1.514 to 1.769, P = 0.005).

    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.

    Objective The aim of this study was to investigate the clinical features, laboratory findings, systemic manifestations, treatment and outcome of patients with bullous systemic lupus erythematosus in a tertiary care center in Thailand. Methods We performed a retrospective review from 2002 to 2014 of all patients who fulfilled the diagnostic criteria for bullous systemic lupus erythematosus to evaluate for the clinical characteristics, extracutaneous involvement, histopathologic features, immunofluorescence pattern, serological abnormalities, internal organ involvement, treatments and outcome. Results Among 5149 patients with cutaneous lupus erythematosus and/or systemic lupus erythematosus, 15 developed vesiculobullous lesions. Ten patients had validation of the diagnosis of bullous systemic lupus erythematosus, accounting for 0.19%. Bullous systemic lupus erythematosus occurred after the diagnosis of systemic lupus erythematosus in six patients with a median onset of 2.5 months (0-89). Four out of 10 patients developed bullous systemic lupus erythematosus simultaneously with systemic lupus erythematosus. Hematologic abnormalities and renal involvement were found in 100% and 90%, respectively. Polyarthritis (40%) and serositis (40%) were less frequently seen. Systemic corticosteroids, immunosuppressants, antimalarials and dapsone offered resolution of cutaneous lesions. Conclusion Bullous systemic lupus erythematosus is an uncommon presentation of systemic lupus erythematosus. Blistering can occur following or simultaneously with established systemic lupus erythematosus. We propose that clinicians should carefully search for systemic involvement, especially hematologic and renal impairment, in patients presenting with bullous systemic lupus erythematosus.

    The purposes of the study were to determine (a) if radiology residents and fellows view their internship year as a valued prerequisite for their career as a radiologist and as a physician, (b) how their postgraduate year (PGY)-1 was perceived with regard to a specific type of internship (i.e., internal medicine, transitional year, or surgery), and (c) how their internship is considered from the vantage point of their current year of training and subspecialty career choice. A survey was sent to all current U.S. radiology residents and fellows from a list derived from the American College of Radiology database. They were polled regarding their experiences in their preliminary year (PGY-1). Responses were coded on a 5-point Likert scale. Response rate for the study was 35%. Although 70% of respondents maintained that their internship year was necessary for their development as a physician, only 49% indicated that it was necessary for their development as a radiologist. Of respondents who graduated from surgical internships, 72% claimed that their PGY-1 was important for their development as a radiologist, compared to 44% of former transitional year interns and 49% of internal medicine interns (Pinternship important to their development as a radiologist (Pinternship year was believed to have merit, the transitional year was least liked by radiology trainees. Efforts should be made to determine why the transitional year does not fare so well in the hope that structural improvements in it can be undertaken to make the year seem more worthwhile and more highly regarded.

    Joining a practice for the first time after training, whether in academia or the private sector, is fraught with challenges and a learning curve. Postgraduate education has not sufficiently taught anyone how to manage the nuances of this new arena or how to become successful. Success is not solely a function measured by reportable taxable income. Respect by colleagues, patients, partners, and staff is just as important, if not more so. The financial attributes will be realized if the tangibles and intangibles discussed are appropriately executed in the correct environment. This article will discuss what to be cognizant of during the first years in academic practice and how to build a foundation for success.
