    Introduction Rupture uterus is a life threatening obstetric complication with serious maternal and fetal side-effects. We report a 3 year (2010-2013) retrospective clinical study of pregnancy with rupture uterus cases attending a tertiary care hospital. Aim The aim of the study was to evaluate the incidence of rupture uterus, incidence as per age, parity, clinical presentations, risk factors, complications and management. Materials and Methods Retrospective data of 74 cases of rupture uterus in SCB Medical college, Cuttack was collected from case records of 26,547 deliveries during a 3 year span (2010-2013). Parameters like cause of rupture, type, site of rupture and outcome were recorded. The collected data was analysed by SPSS software v19. Results Out of 26,547 deliveries during the three year period, there were 74 cases of rupture uterus with an incidence of rupture 1 in 359 (0.28%). The mean age of rupture uterus was 27.4 years. 95.8% were multigravida and majority were referred cases from low socioeconomic status. Only 40.5% had the required minimum of four antenatal visits as recommended by WHO (World Health Organisation). A total of 48.6% of cases with rupture uterus had history of previous Caesarean section. Prolonged labour was present in 75.6% of the cases. Only 12.2% of the cases had history of oxytocin use whereas 9.5% had undergone an operative vaginal delivery. Obstructed labour was the cause in 24.3% of cases, 85.1% had complete rupture. Majority had a rupture in the anterior wall (69%) and 81.1% had rupture in lower segment of uterus. Only 17.6% had broad ligament haematoma, 10.8% colporrhexis and 6.8% had associated bladder injury. Repair was possible in only 39.2% of cases, whereas majority landed up in hysterectomy. Internal iliac ligation was done in 2.7% of cases. Perinatal mortality was 90.5% whereas maternal death was seen in 13.5% cases. One patient developed VVF (vesicovaginal fistula). Duration of hospital stay was upto 14 days in 81.1% cases. Conclusion Education and proper care especially of high risk patients like previous caesarean by competent personnal, proper use of oxytocin and early referral may help to reduce the incidence of “rupture uterus”.

    AIM: To evaluate the credibility of single blastocyst transfer (SBT) method in selected group of patients. SETTINGS AND DESIGN: Retrospective analysis of SBT cases based on computerized data in a private Fertility research centre. MATERIALS AND METHODS: A total of 604 cases of SBTs, done during June 2000 to June 2006, have been analyzed retrospectively to assess the credibility of the method as a method of choice in selective high fertile group of patients. Women between 28 and 42 years have been included in the retrospective analysis, who had adequate number of eggs for fertilization, between 6 and 12. RESULTS AND CONCLUSIONS: Grade I blastocyst transfer resulted in 46.6% of clinical pregnancy and grade II blastocyst transfer resulted in 17.4% of clinical pregnancy rates. Overall pregnancy rate was 64%. Pregnancy loss, as early and late fetal wastages, was 11.06%. PMID:19562057

  5. Case studies of first-year critical science teachers

    NASA Astrophysics Data System (ADS)

    Love, Kurt A.

    Brent Davis and Dennis Sumara (1997) performed a study of themselves and another professor who took a sabbatical to work in an elementary school for a year. Their intentions, as professors focused on cognition, was to create a change in teaching practices throughout the school that aligned more closely with social cognitive research. However, their experiences did not go as planned. Each found that he could not just simply bring their philosophies into their classrooms independent of the sociocultural context of the school. They found very quickly that none of them could act as fully autonomous agents. They described their experiences as being part of the sociocultural fabric of the school because each of their teaching practices changed in ways that they did not anticipate and in ways that were not philosophically aligned. However, they also found that this was a two-way relationship. They were not describing completely deterministic experiences. Davis and Sumara described observing colleagues changing their practices in ways that did incorporate some of the philosophies that they espoused during their tenure at the elementary school. They explain their experience as one where they were pushed and pulled by the sociocultural context and they also pushed and pulled on the sociocultural context. This dissertation focuses on three first-year science teachers (a 4 th grade teacher and two high school science teachers) who identified as wanting to bring critical, feminist, and ecojustice perspectives into their teaching practices. Each enacts these practices much differently in the context of the sociocultural contexts of their own schools, and often changed their teaching practices in ways that seemed to more closely align with those contexts. Each of the three dealt with external and internal hegemonic pressures that caused them to align more closely with their contexts. The philosophical foundations of their sociocultural contexts were manifested externally through technical controls (i.e. district-wide curriculum, state testing, district-wide common assessments, and state standards) and bureaucratic controls (i.e. mandates from administration that reinforce compliance to the technical controls) (Edwards, 1979; Irwin, 1996), sociocultural cues from administrators, colleagues, and students, and were made seemingly impenetrable via intensification, or high workloads that prevent reflective and critical thinking (Apple, 1988; Irwin, 1996). The internalized hegemonic pressures included their own feelings of internalized domination, surplus powerlessness (driven by feelings of isolation and self-blame) (Irwin, 1996; Lerner, 1986), and internalized dispositional views of their students (driven by feelings that their students were not capable of critical social thinking). Each of their case studies focus on how the philosophical differences between the first-year teachers and the sociocultural contexts contrasted providing constant tension for each of the three teachers in terms of their decision-making and their teaching practices. The technical controls seemed to be at the root of most of the external hegemonic pressures and even their internal hegemonic pressures. This paper will focus on the philosophical underpinnings of the state standards in science, the statewide tests, the district curricula, and district-wide common assessments that drove the teachers' practices. The philosophical foundations of their sociocultural contexts were: (1) knowledge as static and objectified, (2) curricular knowledge as the preferred knowledge, (3) standardized testing as a preferred method of gaining data about students' understandings of content, (4) uniform, decontextualized information as "neutral" facts and preferred knowledge, and (5) the summative view of 1-4 as a schooling process that produces learning that is preferred. The first-year teachers' philosophies together contrasted the philosophies of their sociocultural contexts. The first-year teachers held that: (1) knowledge has a deep connection with power in that knowledge is a construction of those in the dominant groups' views of reality, (2) knowledge is not static, but is a co-creative, continuous process, (3) knowledge is a contested terrain, (4) students should be offered the opportunities to explore the knowledge-power relationships, as well as act in their communities to disrupt social and ecological injustices, and (5) the summative view of 1-4 is their preferred view of the schooling process. This study describes how the three teachers responded to the hegemonic pressures of their sociocultural contexts in the form of technical and bureaucratic controls as well as the amplified messages from their colleagues, administrators, and students. This study also describes their own internalized feelings of fear, isolation, and a sense of not being able to make change in their schools. This study focuses on the complex experience of each of the three teachers as they struggle to exert their agency in a context where the ideology is clearly opposed to their own.

    Study Design?Case study. Objectives?We report the case of a 58-year-old Caucasian man, who presented with a 4-month history of increasing low back pain and gait difficulty. Objective neurologic examination revealed a severe paraparetic symptomatology without any sphincter involvement. Methods?Spinal magnetic resonance imaging (MRI) showed an extradural mass formation situated dorsally at the level of thoracic vertebrae T2 to T4. Results?A laminectomy was performed with total removal of the mass; histology suggested a highly vascularized lesion with lobular architecture, which seems a very rare case, compatible with a capillary hemangioma. Conclusions?A careful follow-up for the next 4 years, including control MRIs every postoperative year, showed a very good neurologic condition of the patient and no recurrence on imaging findings.

    Even though there have been previously published reports on firearm injuries in various countries, the incidence and pattern of death from firearm injuries in Thailand have not been studied before. In present study, 149 fatal firearm injuries from 2002 to 2011 were reviewed. At total of 7126 autopsies, fatal firearm injuries comprised of 2.09% (n = 149) of total autopsies cases. Among those victims, 136 were male (91.3%), 13 (8.7%) were female. The youngest age of victim was 10 years and the oldest was 79 years. Mean age of the victims was 33.79 years and median age was 30 years. Outdoor incident was the most common scene of crime. Night time incident (18:00 PM-05:59 AM) was higher than day time one. Most of the cases occurred in week ends (n = 52). Homicide (77.2%) was the most frequent manner of death. Head/face and chest were the most common sites of entrance. The autopsy report also study on entrance wound, range and types of projectiles. Blood alcohol concentration was examined in 122 cases and 38 victims showed positive results, 11 cases revealed using of illegal substances in blood and urine analysis. This study also included the association between manner of death and other factors. Age group, time of incidence, place of incidence, number of entrance wound and range showed statistically significant association with manner of death. PMID:25440139

    Background We aimed to investigate the relation between sunlight exposure and risk of cataract. Methods We carried out a frequency-matched case-control study of 343 cases and 334 controls attending an ophthalmology outpatient clinic at a primary health-care center in a small town near Valencia, Spain. All cases were diagnosed as having a cataract in at least one eye based on the Lens Opacification Classification system (LOCS II). Controls had no opacities in either eye. All cases and controls were interviewed for information on outdoor exposure, "usual" diet, history of severe episodes of diarrhea illness, life-style factors and medical and socio-demographic variables. Blood antioxidant vitamin levels were also analyzed. We used logistic regression models to estimate sex and age-adjusted odds ratios (ORs) by quintiles of years of occupational outdoor exposure, adjusting for potential confounders such as smoking, alcohol consumption, serum antioxidants and education. Results No association was found between years of outdoor exposure and risk of cataract. However, exploratory analyses suggested a positive association between years of outdoor exposure at younger ages and risk of nuclear cataract later in life. Conclusion Our study does not support an association with cataract and sunlight exposure over adult life. PMID:18039367

    Introduction: Cover flaps are needed in management of any bodily defect involving bone, tendon, nerve & vessels. The major objective of a plastic surgeon, facing a complex soft-tissue defect, is to replace “like with like” tissues at minimal donor site “cost” and with maximal accuracy & efficacy. Aims: To study the “Propeller Flaps” utility in reconstructive surgeries, evaluate its planning and complications involving donor site morbidity. Methodology: The prospective study was conducted on 15 cases (11 males/4 females) of propeller flaps during the period of two years (2010-12) in Department of Plastic Surgery and Burns, Bangalore Medical College and Research Institute (BMCRI), Karnataka, India. The propeller flaps were performed in cases with defects due to any cause. Exclusion criteria: Cases with Peripheral Vascular Disease (PVD). Flaps were performed and details recorded. Results: Overall results revealed problem resolution in 87% cases (13 cases). Comprehensive description of each flap type and its related cases are given in the table. It has been categorically found that there were 2 flap partial losses. Partial necrosis has been reported in heavy-smoker patients. Conclusion: This current study clearly justifies that careful application, optimal designing & judicious scientific application of local perforator flaps for lower-limb wounds including rest of the body is successful in many aspects providing high-quality reconstruction ensuring minimal morbidity. It is cost-effective as well as time-saving. PMID:24596732

    PubMed

    Grayson, David N

    2012-01-01

    Thumbsucking is a common habit among younger children. Usually, the child outgrows this habit by age 6. When a child over the age of 6 continues to suck his or her thumb, it can be a cause of potential harm due to peer pressure, ridicule, and shunning. It can also lead to malocclusions requiring eventual orthodontic interventions. In this case study, the author demonstrates a hypnotic intervention in a 7-year-old girl. Validation of her habit and imaging a role model sucking her thumb were employed in trance. Using this approach, the child was able to end her dependence on thumbsucking in 1 session. PMID:22443022

    Objective The purpose of this case study is to describe the effect of chiropractic care on a patient with chronic Bell's palsy. Clinical Features A 47-year-old woman with medically diagnosed Bell's palsy presented for chiropractic care. She had experienced right sinus pressure and congestion, lack of facial tone on the right, and intermittent tingling of the right side of her face. Interventions and Outcomes The patient received high-velocity, low-amplitude chiropractic manipulation (adjustments) to the cervical and thoracic spine, interferential muscle stimulation, and hydroculation on the trapezius muscles bilaterally. Reduction in symptoms occurred following the initial visit and continued over the next 9 weeks of care. After the course of a year of chiropractic care, the patient reached 90% improvement. Conclusions For this patient, chiropractic care reduced Bell's palsy symptoms. PMID:22654687

    2010-01-01

    Background Over 20 years, from October 1989, the Darwin prospective melioidosis study has documented 540 cases from tropical Australia, providing new insights into epidemiology and the clinical spectrum. Principal Findings The principal presentation was pneumonia in 278 (51%), genitourinary infection in 76 (14%), skin infection in 68 (13%), bacteremia without evident focus in 59 (11%), septic arthritis/osteomyelitis in 20 (4%) and neurological melioidosis in 14 (3%). 298 (55%) were bacteremic and 116 (21%) developed septic shock (58 fatal). Internal organ abscesses and secondary foci in lungs and/or joints were common. Prostatic abscesses occurred in 76 (20% of 372 males). 96 (18%) had occupational exposure to Burkholderia pseudomallei. 118 (22%) had a specific recreational or occupational incident considered the likely infecting event. 436 (81%) presented during the monsoonal wet season. The higher proportion with pneumonia in December to February supports the hypothesis of infection by inhalation during severe weather events. Recurrent melioidosis occurred in 29, mostly attributed to poor adherence to therapy. Mortality decreased from 30% in the first 5 years to 9% in the last five years (p<0.001). Risk factors for melioidosis included diabetes (39%), hazardous alcohol use (39%), chronic lung disease (26%) and chronic renal disease (12%). There was no identifiable risk factor in 20%. Of the 77 fatal cases (14%), 75 had at least one risk factor; the other 2 were elderly. On multivariate analysis of risk factors, age, location and season, the only independent predictors of mortality were the presence of at least one risk factor (OR 9.4; 95% CI 2.3–39) and age ?50 years (OR 2.0; 95% CI 1.2–2.3). Conclusions Melioidosis should be seen as an opportunistic infection that is unlikely to kill a healthy person, provided infection is diagnosed early and resources are available to provide appropriate antibiotics and critical care.

    2015-01-01

    This study analysed the evolution of the physical potential of a twice top-10 Grand Tour cycling finisher (Tour de France and Vuelta a España) whose training was monitored between the ages of 18 and 23 years. The world-class cyclist's power output (PO) data and training indices were analysed over six years to determine the evolution of his record power profile and training load (TL), which were estimated by using the session rating of perceived exertion (RPE) method. The total annual duration and TL increased through six seasons by 79% and 83%, respectively. The record POs in all exercise intensity zones improved over the six years. The increases in TL, monotony (+34%) and strain (+162%) from the junior category to the world-class level significantly correlated with an improvement in his aerobic potential, which was characterised by an increase in the record POs between 5 min and 4 h. This case study of the performance level and training parameters of a world-class cyclist provides comprehensive insight into the evolution of a cyclist to the top level. Furthermore, determining the record power profile of this athlete over six competitive seasons illuminates the maturation of the physical potential of a top-10 Grand Tour finisher. PMID:25357188

    2011-11-01

    In 2011 the Department of Energy's Office of Electricity embarked on a comprehensive program to assist our Nation's three primary electric interconnections with long term transmission planning. Given the growing concern over water resources in the western U.S. the Western Electricity Coordinating Council (WECC) requested assistance with integrating water resource considerations into their broader electric transmission planning. The result is a project with three overarching objectives: (1) Develop an integrated Energy-Water Decision Support System (DSS) that will enable planners in the Western Interconnection to analyze the potential implications of water stress for transmission and resource planning. (2) Pursue the formulation and development of the Energy-Water DSS through a strongly collaborative process between the Western Electricity Coordinating Council (WECC), Western Governors Association (WGA), the Western States Water Council (WSWC) and their associated stakeholder teams. (3) Exercise the Energy-Water DSS to investigate water stress implications of the transmission planning scenarios put forward by WECC, WGA, and WSWC. The foundation for the Energy-Water DSS is Sandia National Laboratories Energy-Power-Water Simulation (EPWSim) model (Tidwell et al. 2009). The modeling framework targets the shared needs of energy and water producers, resource managers, regulators, and decision makers at the federal, state and local levels. This framework provides an interactive environment to explore trade-offs, and 'best' alternatives among a broad list of energy/water options and objectives. The decision support framework is formulated in a modular architecture, facilitating tailored analyses over different geographical regions and scales (e.g., state, county, watershed, interconnection). An interactive interface allows direct control of the model and access to real-time results displayed as charts, graphs and maps. The framework currently supports modules for calculating water withdrawal and consumption for current and planned electric power generation; projected water demand from competing use sectors; and, surface and groundwater availability. WECC's long range planning is organized according to two target planning horizons, a 10-year and a 20-year. This study supports WECC in the 10-year planning endeavor. In this case the water implications associated with four of WECC's alternative future study cases (described below) are calculated and reported. In future phases of planning we will work with WECC to craft study cases that aim to reduce the thermoelectric footprint of the interconnection and/or limit production in the most water stressed regions of the West.

    Objective Febrile seizure is one of the most common neurological conditions of childhood. Several theories, such as iron deficiency anemia have been proposed as the pathogenesis of this condition. The aim of this study was to find the association between iron deficiency anemia and febrile seizures in children aged 6 months to 3 years admitted in Valie Asr hospital in Zanjan. Materials &Methods Hemoglobin (Hb), mean corpuscular volume (MCV), serum iron (SI), total iron binding capacity (TIBC) and SI/TIBC ratio were assessed in one hundred children with febrile seizures and compared to the values of one hundred healthy children presenting in a heath care center in the same period as the control group. Results A total of 6% of cases had iron deficiency anemia which was similar to the control group. In the case group SI/TIBC ratio below 12% was seen in 58% of children which was significantly higher than that of the control group (29%). Conclusion The results of this study suggest that although anemia was not common among febrile seizure patients, iron deficiency was more frequent in these patients. PMID:24665277

  1. Gout in a 15-year-old boy with juvenile idiopathic arthritis: a case study

    PubMed Central

    2014-01-01

    Joint pain is a common complaint in pediatrics and is most often attributed to overuse or injury. In the face of persistent, severe, or recurrent symptoms, the differential typically expands to include bony or structural causes versus rheumatologic conditions. Rarely, a child has two distinct causes for joint pain. In this case, an obese 15-year-old male was diagnosed with gout, a disease common in adults but virtually ignored in the field of pediatrics. The presence of juvenile idiopathic arthritis (JIA) complicated and delayed the consideration of this second diagnosis. Indeed, the absence of gout from this patient’s differential diagnosis resulted in a greater than two-year delay in receiving treatment. The patients’ BMI was 47.4, and he was also mis-diagnosed with osteochondritis dissecans and underwent medical treatment for JIA, assorted imaging studies, and multiple surgical procedures before the key history of increased pain with red meat ingestion, noticed by the patient, and a subsequent elevated uric acid confirmed his ultimate diagnosis. With the increased prevalence of obesity in the adolescent population, the diagnosis of gout should be an important consideration in the differential diagnosis for an arthritic joint in an overweight patient, regardless of age.

    1989-01-01

    Rotavirus infections were detected in 210 of 675 children with acute diarrhea admitted to a major pediatric hospital in Rome from January 1982 through December 1985. Most of the patients with rotavirus infections were admitted during the winter season in both 1982 and 1985, whereas during the two intermediate years, cases occurred in all months. Among 84 rotavirus samples examined, 14 different electropherotypes were recognized, 2 of which largely predominated over the others. The two electropherotypes were particularly frequent in the 2 epidemic years, altogether accounting for 70.2% of the samples typed, and circulated in distinct periods. None of the viruses showed a short pattern of electrophoretic migration of the genome, indicating a minor involvement of subgroup I rotaviruses in hospitalization-requiring diarrheas occurring in the area surveyed.

    2015-01-01

    Atresia of the aortic arch is a rare congenital heart defect with a high mortality when associated with other intracardiac defects. Cardiac magnetic resonance (CMR) provides the exact anatomy of the aortic arch and collateral circulation and is useful to diagnose-associated aortic arch anomalies. This report describes the case of a 4-year-old child with atresia of the aortic arch, referred to our institution with the diagnosis of aortic coarctation and bicuspid aortic valve. On clinical exam, the femoral pulses were not palpable and there was a significant differential blood pressure between the upper and lower limbs. The echocardiography showed a severely stenotic bicuspid aortic valve but was limited for the exact description of the aortic arch. CMR showed absence of lumen continuity between the ascending and descending aorta distal to the left subclavian artery, extending over 5?mm, with the presence of a bend in the arch and diverticulum on either side of the zone of discontinuity, suggesting the diagnosis atresia of the aortic arch rather than coarctation or interruption. The patient benefited from a successful surgical commissurotomy of the aortic valve and reconstruction of the aortic arch with a homograft. The post-operative CMR confirmed the good surgical result. This case emphasizes the utility of CMR to provide good anatomical information to establish the exact diagnosis and the operative strategy. PMID:25853109

  15. One hundred years: A collective case study of climate change education in Georgia

    NASA Astrophysics Data System (ADS)

    Bloch, Leonard Mark

    This collective case study examined how five K-12 science teachers taught about climate change during Fall 2013, and asked how the University of Georgia can support climate change education. The participants were all experienced teachers, and included: three high school teachers, a middle school teacher, and an elementary school teacher. 'Postcarbonism', an emerging theoretical framework, shaped the research and guided the analysis. The teachers varied in their teaching practices and in their conceptions of 'climate change', but they were united in: 1) their focus on mitigation over adaptation, and 2) presenting climate change as a remote problem with simple solutions. The teachers drew on varied resources, but in all cases, their most valuable resources were their own skills, knowledge and personality. The University of Georgia can support climate change education by developing locally relevant educational resources. Curriculum developers might consider building upon the work of outstanding teach.

    The paper first studied the geometric correction of historical CORONA satellite imagery in the 1960s and used the historical imagery to extract KRD (karst rocky desertification). The study area is located in the karst region of Guangxi Province, China. Finally, we used the Landsat-5 imagery to extract rocky desertification in 2005, then we could find the changes of the karst rocky desertification in Guangxi from 1960s to 2005 about nearly 40 years. And comparison analysis was conducted and the results showed that, over the 40 years, Guangxi karst rocky desertification area has significantly changed. Guangxi has typical karst environment and is one of the most serious areas of rocky desertification in southwest China provinces, thus our research on this has great practical significance.

    Veterinary toxicoses are frequently observed in western Canada. This study reports the frequency and characteristics of intoxications in animals reported between January 1, 1998 and December 31, 2013. Information was obtained from toxicological case records from the Prairie Diagnostic Services, Saskatoon, Saskatchewan. There were 1341 animal poisonings with 19 compounds over the investigational period. Lead poisoning was the most common toxicity (43.7%). Poisoning with acetylcholinesterase inhibitors and strychnine were also common events. Poisonings were most common in 2001, 2009, and 2012. Intoxications occurred most frequently during the months of May through July. Cattle were the most commonly poisoned species (n = 696), followed by dogs and eagles. PMID:26740698

    The open plan office design concept has been around for at least 45 years. Through research, design, and practical experience, the basic concepts and parameters that impact acoustics and speech privacy have been fairly well developed and documented. The psychological aspects of human response and expectation to open plan environments, and the conceptual designs that emerge from the architect and interior designers are frontiers that still allow for ongoing study. A large open plan project completed during the dot-com bubble allowed an opportunity to design and experience an unusual open plan environment that utilized exposed sound masking system loudspeakers and minimal sound absorption.

    OBJECTIVE: To compare the functional outcome of patients with and without arthrosis, and to determine whether the development of arthrosis is related to the distance of the tumor from the subchondral bone. METHODS: Forty six patients treated for Giant-cell tumor (GCT) between 1975 and 1999 met inclusion criteria. GCT was diagnosed by percutaneous biopsy and confirmed after resection, in all cases. Campanacci's and Kellgren's classification, the distance of the cement to the articular surface and MSTS score were obtained throughout the sample. RESULTS: The distance of the cement to the subchondral bone was associated with greater risk of developing arthrosis, but there was no difference in MSTS scores between patients with or without arthrosis. CONCLUSION: We found that the distance from the cement to the subchondral bone has a prognostic value regarding future arthrosis, but it does not impact on the functional outcome.

    Introduction Transaortic valve implantation (TAVI) has a well-established position in the treatment of high-risk and inoperable patients with severe aortic stenosis (AS). The TAVI protocol requires a pre-dilatation for native valve preparation. Aim To assess the safety and feasibility of TAVI without pre-dilatation and to compare it with the procedure with pre-dilatation. Material and methods Out of 101 TAVI patients, in 10 the procedure was performed without balloon predilatation, and 8 patients were included in the analysis. The procedural, echocardiographic, and clinical outcomes were compared with a case control matched cohort (1: 2 ratio). A 12-month follow-up was done in all cases. Results The procedure was successfully completed in all patients in the study group (SG), but there was one procedural failure in the control group (CG). All patients received a CoreValve (Medtronic) bioprosthesis. There was a significant immediate decrease in transvalvular gradients (TG) in both study arms after the procedure (SG: mean TG: from 46.0 ±14.0 mm Hg to 10.0 ±4.8 mm Hg, p < 0.001; CG: mean TG: from 55.9 ±12.0 mm Hg to 9.9 ±2.9 mm Hg, p < 0.001). A marked increase in the effective orifice areas was observed in both cohorts (SG: 1.63 ±0.13 cm2 and CG: 1.67 ±0.25 cm2, p = 0.75). The periprocedural complication rate was equally distributed in both arms. The 12-month all-cause mortality was 12.5% in both groups. Conclusions The direct TAVI approach seams to be safe and feasible. The clinical and echocardiographic results are not different from those achieved in patients treated with standard TAVI protocol with pre-dilatation. PMID:25489318

    2015-03-01

    Temperature and egg viability data from an Arctic charr Salvelinus alpinus hatchery covering a period of 28 years were analysed. During the study period, there was a significant increase in the mean water temperature in May, July, August and September of c. 2° C. Independent of year, the egg viability showed a negative correlation with the mean monthly temperatures in July, August and September as well as with the temperature difference between October and November. The negative effect of high summer temperatures was further supported by a comparison of egg viability from replicate broodstock reared at two sites differing mainly in summer water temperature. The eggs from the colder site were, on average, significantly larger (4·4 mm compared with 4·0 mm) and had higher hatching rates (57% compared with 37%). These results suggest that unfavourable temperature conditions during the summer and autumn can explain much of the excessive egg mortality experienced at the main facility used for the Swedish S. alpinus breeding programme. The main effect was supra-optimal temperatures during the period July to September, but there also appears to have been an effect from the temperature regime before and during spawning (October to November) that was unrelated to the summer temperatures. These findings emphasize the importance of site selection and sustainable management of aquaculture hatcheries in the light of the ongoing climate change. PMID:25683742

    Objectives: This study was conducted to assess the clinic-epidemiological profile of snakebite cases admitted at a Tertiary Care Centre in South India. Materials and Methods: A record based retrospective study was carried out at Kasturbha Medical College affiliated hospitals in Mangalore. All the snakebite cases admitted to the hospitals from January 2007 to December 2011 were included in the study. Data were collected using a pretested semi-structured questionnaire and analyzed using Statistical Package for Social Sciences (SPSS version 11.5). The results are expressed as percentages. Results: The study included 198 cases of snakebite victims. The majority of the cases were males (68.2%). The mean age of the study population was 34.8 years. Maximum numbers of snakebite cases were reported during the month of September to December (47.9%). The peak time of snakebite was between 18.01 and 24.00 h which was reported in 40.5% of the cases. Lower extremities were the most common site of bite in more than three-fourth of the cases (80.9%). The most common symptoms were a pain (45.9%) and swelling (44.9%). The case fatality rate was observed to be 3.0%. Conclusion: Snakebite still remains a major public health problem in this part of the world. Knowledge must be imparted regarding the prevention of snakebites through community health programs. Messages regarding prompt reporting of such cases and importance of effective treatment must be disseminated among people through mass media and role plays. PMID:26862263

    AIM To determine the epidemiological characteristics, clinical signs, laboratory findings, and outcomes in patients with corneal infection in Shandong peninsula of China. METHODS The medical records of 578 inpatients (578 eyes) with corneal infection were reviewed retrospectively for demographic characteristics, risk factors, seasonal variation, clinical signs, laboratory findings, and treatment strategy. Patient history, ocular examination findings using slit-lamp biomicroscopy, laboratory findings resulted from microbiological cultures, and treatment. RESULTS Fungal keratitis constituted 58.48% of cases of infectious keratitis among the inpatients, followed by herpes simplex keratitis (20.76%), bacterial keratitis (19.03%) and acanthamoeba keratitis (1.73%). The most common risk factor was corneal trauma (71.80%). The direct microscopic examination (338 cases) using potassium hydroxide (KOH) wet mounts was positive in 296 cases (87.57%). Among the 298 fungal culture-positive cases, Fusarium species were the most common isolates (70.47%). A total of 517 cases (89.45%) received surgical intervention, including 255 (44.12%) cases of penetrating keratoplasty, 74 (12.80%) cases of lamellar keratoplasty which has become increasingly popular, and 77 cases (13.32%) of evisceration or enucleation. CONCLUSION At present, infectious keratitis is a primary corneal disease causing blindness in China. With Fusarium species being the most commonly identified pathogens, fungal keratitis is the leading cause of severe infectious corneal ulcers in Shandong peninsula of China. PMID:26949610

    Thymic tumors with adenoid cystic carcinoma-like features are true rarities, with only 6 cases reported. Our knowledge of their clinical behavior is insufficient. We present a case of a noninvasive cribriform tumor that was followed, including a 4-year period after tumor resection and radiation therapy, for a total of 9 years. The tumor was purely epithelial. It was positive for keratins (AE-1/AE-3, CK19, 34?E12,CK5/6), MOC-31, P63, P40, CD10, and MYB, and was negative for myoepithelial or neuroendocrine markers. Presence of cell processes, desmosome-like junctions with tonofilaments and multifocally reduplicated basal lamina was noted on ultrastructural examination. Two signals of the MYB gene per cell were detected by fluorescence in situ hybridization. No monosomy or translocations of the gene were found. Although additional clinical studies are necessary, it seems that indolent behavior of cribriform noninvasive subset of these tumors may be anticipated. PMID:26194601

    Background and objectives: Objective in this retrospective study is to find out the incidence of different ovarian tumors of girls up to 20 years of age observed in last ten years in North Bengal Medical College and to correlate clinical and gross findings with histopathologic findings and to compare the incidence with other studies and follow-up of patients with malignant ovarian tumors. Materials and Methods: Findings were retrieved from records of different pathological reports and clinical reports. Results: Total 151 cases of ovarian tumors were received in pathology department in which 34 cases were malignant (22.6%). Amongst malignant cases, 66% are of germ-cell origin–dysgerminoma being the commonest. Strikingly we got 9 cases of malignant surface epithelial tumor. As per follow-up records most of the dysgerminoma came in stage IA and recovered fully following chemotherapy and radiotherapy. Amongst other malignant tumors, few lost the follow-up management and others expired due to metastasis. Conclusions: Patients from hilly areas of North Bengal and low socio-economic status led to lower detection rate of ovarian tumors in early stage which are absolutely necessary for proper guidelines of management to reduce mortality.

    Although studies have described factors associated with pertussis hospitalization in children, data on adult hospitalization are sparse. We examined the association between patient characteristics and hospitalization among older adults with pertussis. We conducted a nested case-control study of participants in the 45 and Up prospective cohort in New South Wales, Australia, with an incident pertussis diagnosis during 2006-2012. Cases were defined as those with a hospitalization coded as 'whooping cough' or 'non-specific respiratory disease/cough' between a week prior and 6 weeks after the diagnosis of pertussis based on laboratory tests. Controls were participants diagnosed with pertussis but not hospitalized. Among 265,287 participants, the incidence of pertussis and pertussis hospitalization was 83.9 (95% [confidence interval] CI, 78.7-89.6) and 2.9 (95% CI, 2.1-4.1)/100,000 person-years, respectively. Among 33 cases and 882 controls, factors associated with hospitalization were increasing age (compared to those 45-54 years, adjusted odds ratio [aOR] 5.4 (95% CI, 1.6-18.2) and 8.9 (95% CI, 2.3-34.7) in those aged 65-74 years and 75+ years, respectively) and smoking (ever versus never, aOR 2.37 (95% CI, 1.11-5.06)). The risk of pertussis hospitalization is substantially higher in ≥65 years old. A booster dose of diphtheria-tetanus-pertussis vaccine could be readily integrated into routine vaccination for this age group. PMID:26335770

    A retrospective study was conducted at Tongji Forensic Medical Center in Hubei (TFMCH) from 1999 to 2014. Forty-nine cases of sudden unexplained nocturnal death syndrome (SUNDS) were collected. The SUNDS rate was 1.0% in the total number of cases, in which an incidence was fluctuating over the years. Interestingly, April and January, and 3:00 to 6:00 AM were the peak months and times of death. Among the decedents, farmers and migrant workers accounted for 67.3%. The syndrome predominantly attacked males in their 30s. One victim had sinus tachycardia. Thirteen victims (26.5%) were witnessed and had abnormal symptoms near death. Macroscopically, compared to sudden noncardiac deaths, the weights of brain, heart, and lungs had no statistical difference in SUNDS. Microscopically, the incidence of lung edema (45 cases, 91.8%) was significantly higher in SUNDS group than in the control group (27 cases, 55.1%). 82.9% of 35 SUNDS cases examined displayed minor histological anomalies of the cardiac conduction system (CCS), including mild or moderate fatty, fibrous or fibrofatty tissue replacement, insignificant stenosis of node artery, and punctate hemorrhage in the node area. These findings suggested that minor CCS abnormalities might be the substrates for some SUNDS deaths. Therefore, SUNDS victims might suffer ventricular fibrillation and acute cardiopulmonary failure before death. Further in-depth studies are needed to unveil the underlying mechanisms of SUNDS.

    We report a long-term follow-up investigation of a patient who was operated in 1954 to relieve intractable temporal lobe seizures characterized by automatism and amnesia. Neuropsychological review at 16 months after surgery showed a slight residual impairment of verbal comprehension and verbal recall and good nonverbal skills. Seizure-free since the operation except for two attacks in the early postoperative years, the patient has been off medication for 25 years and has pursued a successful career as an artist. Our investigation at 56 postoperative years focused on cognitive skills, with some emphasis on learning and memory; a clinical examination was also performed, and the anatomical extent of the resection was determined on 3-Tesla magnetic resonance imaging. Four age- and IQ-appropriate women were tested as healthy control subjects. The patient showed material-specific impairments in language and verbal memory compared with the control subjects and also compared with her own earlier performance, but her performance on other cognitive tasks did not differ from that of the control subjects. Thus, her specific deficits had worsened over time, and she was also impaired compared with healthy individuals of her age, but her deficits remained confined to the verbal sphere, consistent with her temporal lobe seizure focus and surgery.

  2. Risk factors for unintentional poisoning in children aged 1–3 years in NSW Australia: a case–control study

    PubMed Central

    2013-01-01

    Background Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1–3 years have the highest levels of poisoning risk among children aged 0–4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the current study is to investigate a broad range of potential risk factors for unintentional poisoning in children aged 1–3 years using appropriate methodologies. Methods Four groups of children, one case group (children who had experienced a poisoning event) and three control groups (children who had been ‘injured’, ‘sick’ or who were ‘healthy’), and their mothers (mother-child dyads) were enrolled into a case–control study. All mother-child dyads participated in a 1.5-hour child developmental screening and observation, with mothers responding to a series of questionnaires at home. Data were analysed as three case–control pairs with multivariate analyses used to control for age and sex differences between child cases and controls. Results Five risk factors were included in the final multivariate models for one or more case–control pairs. All three models found that children whose mothers used more positive control in their interactions during a structured task had higher odds of poisoning. Two models showed that maternal psychiatric distress increased poisoning risk (poisoning-injury and poisoning-healthy). Individual models identified the following variables as risk factors: less proximal maternal supervision during risk taking activities (poisoning-injury), medicinal substances stored in more accessible locations in bathrooms (poisoning-sick) and lower total parenting stress (poisoning-healthy). Conclusions The findings of this study indicate that the nature of the caregiver-child relationship and caregiver attributes play an important role in influencing poisoning risk. Further research is warranted to explore the link between caregiver-child relationships and unintentional poisoning risk. Caregiver education should focus on the benefits of close interaction with their child as a prevention measure. PMID:23705679

    The aim of this study was to determine whether a high degree of dental caries severity is associated with the distal and proximal determinants of caries in a group of Brazilian adults aged 35 to 44 years. A population-based case-control study was conducted using two groups-a case group with high caries severity (DMFT ? 14) and a control group without high caries severity (DMFT < 14). The sample comprised adults from metropolitan Belo Horizonte, Brazil (180 cases and 180 controls matched for gender and age). The exam was performed by calibrated dentists using the DMFT index. The statistical analysis used the Mann-Whitney test and bivariate and multivariate logistic regression (the conditional backward stepwise method). The mean DMFT was 8.4 ± 3.9 in the control group and 20.1 ± 4.5 in the case group. High caries severity was associated with regular visits to the dentist, low income, use of private/supplementary dental service and not petitioning the authorities for community benefits. The results of the study underscore the importance of considering distal and proximal factors in the assessment of the severity of dental caries. Greater caries severity persists among low-income families and among groups with a low degree of social cohesion. PMID:23749056

    2015-10-01

    In this work, a specific implementation of a so-called experimental or open-ended laboratory is proposed and evaluated. Keeping in mind the scheduling limitations imposed by the context, first-year engineering physics laboratory practices have been revised in order to facilitate acquisition of the skills that are required in the experimental work. These skills concern different conceptual and procedural abilities related to designing experiments, taking measurements, analyzing the results and reporting properly the whole process. The employed approach is described, and the achieved results are evaluated by a series of tests at the beginning and end of the academic year. Additionally, the students' laboratory reports are used to quantify the evolution of acquiring these scientific skills. The evaluation of the results obtained from the aforementioned tests and laboratory reports gives enlightening information about students' apprehension of the experimental method itself, as well as the difficulties they find in each of the different, complex tasks that they must carry out during this process.

    2011-09-01

    This case study reports the results of a 6-year (2005-2010) follow-up study of a world-class rowing crew, the current world champions. The rowers were 15-16 years old and prospective competitors at the junior level when the study began in 2005, and we monitored their physical, physiological, and rowing ergometer performance data annually. Our findings indicated that over the 6-year period gains in stature, averaged across rowers, amounted to only +2 cm (+1%). In contrast, body mass increased by +9 kg (+10%) and fat-free mass by +11 kg (+15%). A significant linear trend (R (2) = 0.998, P < 0.001) and a +26% increase in maximal oxygen uptake (in L min(-1)) was evident from 2005 to 2009, resulting in a leveling-off and a crew average of ~6.6 L min(-1) (~70 mL kg(-1) min(-1)) during the last 2 years of assessment. Power output at anaerobic threshold increased by +23%, subsequently amounting to a crew average of 359 W in 2010. Oxygen uptake at anaerobic threshold, expressed as a percentage of maximal oxygen uptake, changed little and ranged between 82 and 85%. A curvilinear regression provided the best fit to describe the 6-year improvement (+7%) in 2000 m (R (2) = 0.984, P < 0.001) and 6000 m (R (2) = 0.989, P < 0.001) rowing ergometer performance times. Performance-related physical and physiological parameters seem to level-off at about 20 years of age, which may partly explain the corresponding stabilization in ergometer performance times over the last years of assessment.

    Begun in 2005, the Building Strong Geoscience Departments project sought to help geoscience departments respond to changes in geosciences research, academic pressures, and the changing face of the geosciences workforce by working as a team, planning strategically, and learning from the experiences of other geoscience departments. Key strategies included becoming more central to their institution's mission and goals; articulating the department's learning goals for students; designing coordinated curricula, co-curricular activities, and assessments to meet these goals; and recruiting students effectively. A series of topical workshops identified effective practices in use in the U.S. and Canada. These practices were documented on the project website and disseminated through a national workshop for teams of faculty, through activities at the AGU Heads and Chairs workshops, and in a visiting workshop program bringing leaders to campuses. The program has now involved over 450 participants from 185 departments. To understand the impact of the program, we engaged in ongoing discussion with five departments of various sizes and institutional types, and facing a variety of immediate challenges. In aggregate they made use of the full spectrum of project offerings. These departments all reported that the project brought an important new perspective to their ability to work as a department: they have a better understanding of how their departments' issues relate to the national scene, have more strategies for making the case for the entire department to college administrators, and are better poised to make use of campus resources including the external review process. These results were consistent with findings from end-of-workshop surveys. Further they developed the ability to work together as a team to address departmental challenges through collective problem solving. As a result of their workshop participation, two of the departments who considered their department to be vulnerable to elimination believe they are in a better position to survive and thrive. All five departments reported changes to their curriculum that addressed goals such as attracting more majors, recruiting students from underrepresented groups and integrating initiatives such as service learning. Three departments reported making strides to increase their visibility by implementing new community activities, involving alumni, and using social networking. Two departments became more intentional in collecting data for assessment/external review. As one department member shared, they learned that it was not enough to just teach and to do good research, they became their own advocates for change and believe it made a significant difference in their success on campus.

    2000-05-01

    This report describes a case study of the development of an infant with autism who was observed closely by professionals from birth and to whom a comprehensive psychological evaluation was administered at approximately 1 and 2 years of age. During the first 6 months of life, this infant displayed difficulties in oral motor coordination and muscle tone that fluctuated between hypotonia and hypertonia. He startled easily, had poor state regulation, and was hypersensitive to touch. Notably, however, during the first 6 months, this infant vocalized and responded socially to others by smiling and cooing. During the second half of the first year, he continued to demonstrate diffuse sensorimotor difficulties and diminished oral motor control. Hypersensitivity now extended to a wider range of stimuli. He had problems in sleep regulation. Motor stereotypies, including rocking, head banging, and toe walking, were observed. Difficulties in the domain of social interaction began to emerge during the second 6 months, including poor eye contact, failure to engage in imitative games, and lack of imitative vocal responses. By a little over 1 year of age, this infant met diagnostic criteria for autism based on the Autism Diagnostic Interview. There were several domains in which this toddler with autism did not show impairments. In the areas of immediate memory for actions, working memory, response inhibition, and speech perception, this 1-year old with autism displayed no evidence of significant impairment on the tests administered. This case study offers clues regarding the nature of autism at its earliest stages. Understanding early development in autism will be important for developing early screening and diagnostic tools.

    2011-01-01

    Objective The purpose of this article is to present a case study of chiropractic spinal manipulative treatment (CSMT) using the Gonstead method for a patient with migraines. Clinical Features The patient was a 52-year-old married woman with a long-term history of chronic migraines, which included nausea, vomiting, and photophobia. The patient had endometriosis, but did not relate the migraines to her menstrual cycles. She also reported not using medication for her migraines due to previous drug-related issues. The average frequency of episodes before treatment was 1 per month, and her migraines often included an aura. The pain was moderate, was located on the right side, was pulsating, and lasted for approximately 15 hours. The numeric pain scale for an average episode was 8 out of a possible 10. The aura involved nausea, photophobia, and visual disturbances including black dots in the visual field lasting for approximately 10 minutes. Intervention and Outcome The patient reported all episodes being eliminated following CSMT. At 6-month follow-up, the patient had not had a single migraine episode in this period. The patient was certain that there had been no other lifestyle changes that could have contributed to her improvement. Conclusion This case adds to previous research suggesting that some migraine patients may respond favorably to CSMT. The case also provides information on the Gonstead method. A case study does not represent significant scientific evidence in context with other studies conducted; this study suggests that a trial of CSMT using the Gonstead methods could be considered for chronic, nonresponsive migraines.

    The 520 million-year-old Chengjiang biota of China (UNESCO World Heritage) presents the earliest known evidence of the so-called Cambrian Explosion. Studies, however, have mainly been limited to the information exposed on the surface of the slabs. Thus far, structures preserved inside the slabs were accessed by careful removal of the matrix, in many cases with the unfortunate sacrifice of some “less important” structures, which destroys elements of exceptionally preserved specimens. Here, we show for the first time that microtomography (micro-CT) can reveal structures situated inside a Chengjiang fossil slab without causing any damage. In the present study a trilobitomorph arthropod (Xandarella spectaculum) can be reliably identified only with the application of micro-CT. We propose that this technique is an important tool for studying three-dimensionally preserved Chengjiang fossils and, most likely, also those from other biota with a comparable type of preservation, specifically similar iron concentrations.

    Objectives: The objective of this study was to analyze the frequency and distribution of odontogenic tumors (OTs) in the Cappadocia region of Turkey, and to compare the findings with those reported in the literature. Study Design: The records of the Oral and Maxillofacial Surgery and Pathology Departments at Erciyes University, with histologic diagnosis of odontogenic tumors (based on the World Health Organization classification, 2005), over a 12-year period, were analyzed. The relative frequency of different types of tumors was also analyzed and compared with the literature. Results: OTs in the present study constituted 2.74% of all the 7,942 registered biopsies. A total of 218 cases of OTs were collected and reviewed. Of these, (94.04%) were benign and (5.96%) were malignant. The mandible was the most commonly affected anatomic location, with 170 cases (77.9%). Ameloblastoma with a predilection for the posterior mandible was the most frequent odontogenic tumor (30.28%), followed by keratocystic odontogenic tumor (19.5%), odontoma (13.4%), and odontogenic myxoma (8.5%). Conclusions: OTs are rare neoplasms and appear to show geographic variations in the world. In Cappadocia, Turkey, they are more common in the mandible, with ameloblastoma followed by keratocystic odontogenic tumors with the incidences observed in the present study being similar to those of previous studies from Asia and Africa, and in contrast to those reported from American countries.

    Objectives The use of osseointegrated implants as an endoestal anchorage device to provide support for dental prostheses is a reliable and widely accepted treatment modality. The purpose of this study was to evaluate the clinical performance of non-submerged implants placed in the maxilla or in the mandible. Methods A total of 146 International Team for Implantology (ITI) (Straumann AG, Waldenburg, Switzerland) implants were placed in 42 patients (20 women, 22 men, mean age 42). The cases were examined retrospectively in order to evaluate the clinical efficiency of non-submerged ITI implants and to determine the success rate of implant retained/supported prosthesis after a 5-year period. All implants were assessed clinically and radiographically on a yearly basis. Results The 5-year cumulative success rates for maxillary and mandibular implants were 91.00% and 97.81%, respectively. The most common prosthetic complication was abutment accompanied by screw loosing (3.42%). Veneering material fracture was documented in only one patient. Conclusions Within the limitations of the observation period and sample number, the present findings confirmed sufficient success and survival rates of ITI implants placed in mandible as well as implants placed in the maxilla after a 5-year period.

    Data from a study on malignant ovarian tumors in pregnancy in Israel are presented. During the 25-year period of the survey, 23 new cases of malignant ovarian tumors during pregnancy were diagnosed, representing an incidence of 0.12/100,000 females over the age of 14; over half of the patients were in their third decade of life at the time of diagnosis of the tumor. Ovarian malignant tumors during pregnancy are more prevalent in Jewish women of European-American origin than in those of Asian-African descent. Borderline carcinomas were found in 35% of our patients; epithelial invasive tumors were found in 30%; the other tumors were dysgerminoma (17%), granulosa cell tumor (13%), and undifferentiated carcinoma (5%). Most of the patients (74%) were diagnosed in stage I. In three cases, ovarian cancer was diagnosed during surgery for tubal pregnancy, and in two during cesarean section at term. In early-stage disease and low-potential-malignancy tumors, surgery can be conservative; thus, 14 of 23 bore a live child. In advanced disease, aggressive surgery, chemotherapy, and/or radiotherapy should be instituted. Factors affecting prognosis were age of patient, histologic type of tumor, and clinical stage of disease. Overall, the survival is much better than that for ovarian tumors in general, because most of the tumors are of low potential malignancy and are diagnosed at an early stage. PMID:2722058

    The increased demand for waste wood (WW) as fuel in Swedish co-combustion facilities during the last years has increased the import of this material. Each country has different laws governing the use of chemicals and therefore the composition of the fuel will likely change when combining WW from different origins. To cope with this, enhanced knowledge is needed on WW composition and the performance of pre-treatment techniques for reduction of its contaminants. In this study, the chemical and physical characteristics of 500 WW samples collected at a co-combustion facility in Sweden between 2004 and 2013 were investigated to determine the variation of contaminant content over time. Multivariate data analysis was used for the interpretation of the data. The concentrations of all the studied contaminants varied widely between sampling occasions, demonstrating the highly variable composition of WW fuels. The efficiency of sieving as a pre-treatment measure to reduce the levels of contaminants was not sufficient, revealing that sieving should be used in combination with other pre-treatment methods. The results from this case study provide knowledge on waste wood composition that may benefit its management. This knowledge can be applied for selection of the most suitable pre-treatments to obtain high quality sustainable WW fuels. PMID:26709051

    The same aggressive treatments that have led to a reduction in the breast cancer may also have adverse effects on cardiac autonomic balance. The objective of this study was to compare heart rate variability (HRV) between breast cancer survivors in the first year posttreatment and healthy women, controlling for known confounders. This descriptive case-controlled study included 22 breast cancer survivors and 22 healthy age- and sex-matched controls. Short-term HRV was measured using an accepted methodology to assess the cardiac autonomic balance. One-way analysis of covariance results revealed that heart rate was significantly higher (F = 15.86, p < .001) and the standard deviation of normal-to-normal (NN) interval (F = 19.93, p = .001), square root of mean squared differences of successive NN intervals (F = 18.72, p = .001), HRV index (F = 5.44, p = .025), and high-frequency (F = 5.77, p = .03) values were significantly lower in the breast cancer survivors than in the matched controls. The principal finding of the presence of a cardiovascular imbalance in breast cancer survivors in comparison to healthy age-matched controls suggests that HRV study could be a clinically useful tool to detect cardiovascular disease in early-stage breast cancer survivors.

    AIM To investigate the original protopathy, direct indications, clinical characteristics, complications of orbit plants and visual conditions of eye enucleation/evisceration. METHODS A retrospective study of 573 eyes removed (573 inpatients) at Ophthalmology Department in a tertiary care center of China from January 1993 to December 2012 was completed. RESULTS Cases underwent removal of the eye accounted for 2.15% of total ophthalmology inpatients, whose annual frequency declined from 3.80% to 0.52%. There were 167 eyes (29.14%) being enucleated and 406 (70.86%) eviscerated. Annual proportion of evisceration rose from 16.67% in 1993 to 90.48% in later years. Trauma was the top one (65.62%) in original protopathies followed by neoplasm (13.44%) and ocular infections (5.76%). Phthisis bulbi (45.20%) was the most common direct indication, succeeded by malignant tumor (12.57%), loss/unreconstructed of intraocular tissues due to trauma (11.00%), untreatable inflammation (9.60%), intractable glaucoma (8.55%) and sclerocorneal staphyloma (5.24%). Exenteration was underwent in 20 (25.97%) cases (40% for recurrent carcinoma). Following evisceration, secondary prosthesis implantation was more and earlier, implant exposure occurred in less but earlier and infection and extraction/exchange of implants were more than those following enucleation. Male, phthisis bulbi, evisceration and secondary implantation meant lower risk of implant exposure; eyes removed within 24h following trauma was an independent risk factor. There were 14.37% of eyes with vision of light perception at least as been removed. In the residual contralateral eyes, low vision accounted 5.58% and blindness 3.14%. CONCLUSION Ocular trauma, tumor and infections were great threats to eyeball preservation. Early and effective controlling of any original protopathies was vital. Generally evisceration presented more superior and safe outcomes than enucleation did. Visual conditions of the sufferers should be focused on. PMID:26558221

    Background The signal of an association between vaccination in the second year of life with a hexavalent vaccine and sudden unexpected deaths (SUD) in the two days following vaccination was reported in Germany in 2003. A study to establish whether the immunisation with hexavalent vaccines increased the short term risk of SUD in infants was conducted in Italy. Methodology/Principal Findings The reference population comprises around 3 million infants vaccinated in Italy in the study period 1999–2004 (1.5 million received hexavalent vaccines). Events of SUD in infants aged 1–23 months were identified through the death certificates. Vaccination history was retrieved from immunisation registries. Association between immunisation and death was assessed adopting a case series design focusing on the risk periods 0–1, 0–7, and 0–14 days after immunisation. Among the 604 infants who died of SUD, 244 (40%) had received at least one vaccination. Four deaths occurred within two days from vaccination with the hexavalent vaccines (RR?=?1.5; 95% CI 0.6 to 4.2). The RRs for the risk periods 0–7 and 0–14 were 2.0 (95% CI 1.2 to 3.5) and 1.5 (95% CI 0.9 to 2.4). The increased risk was limited to the first dose (RR?=?2.2; 95% CI 1.1 to 4.4), whereas no increase was observed for the second and third doses combined. Conclusions The RRs of SUD for any vaccines and any risk periods, even when greater than 1, were almost an order of magnitude lower than the estimates in Germany. The limited increase in RRs found in Italy appears confined to the first dose and may be partly explained by a residual uncontrolled confounding effect of age. PMID:21298113

    All incident cases of diabetes mellitus in the age group 15 to 34 years have been prospectively registered in Sweden since January 1983. To analyse the utilization of outpatient services 8 years after disease onset, we selected the cases registered in 1983 and two controls per case from the general population, matched by age, gender, and county of residence. In 1991, retrospective data about utilization patterns during a 3-month period were collected via a mailed questionnaire, returned by 317 (72%) patients with diabetes and 586 (68%) controls. Seventy-four percent of the cases and 19% of the controls reported at least one visit to a hospital outpatient clinic, including accident and emergency departments. The odds ratio for one visit was 14 (95% CI 9.6-20), for two visits 11 (95% CI 7.0-18), and for three or more visits 8.9 (95% CI 5.6-14). Even when specialized diabetes clinics were excluded from the analysis, the cases had higher odds for visits to internal medicine clinics, to ophthalmology clinics, and to gynaecology clinics, but not for visits to surgical clinics or to accident and emergency departments. Of non-hospital outpatient services, only visits to nurse practitioners were reported by a higher percentage of diabetic responders. Twenty-seven percent of patients with diabetes, as compared to 9% of the controls, had visited both hospital and non-hospital outpatient offices. Females were overrepresented among diabetic high-consumers. The results indicate that most young to middle-aged Swedish persons with diabetes are monitored at hospital outpatient offices, but considerable overlap exists between hospital and non-hospital outpatient services. Further research is needed into the determinants of utilization patterns in diabetes, such as gender. PMID:8973888

    The objective of this study was to characterize the cortical activity pattern of one patient who received bilateral forearm transplants. Using fMRI we acquired motor and sensory brain activity every year after surgery and during three consecutive years while the patient underwent physical rehabilitation. The motor related cortical activity evaluated during the first year showed a sparse pattern involving several brain regions. Over time, the analysis showed a progressive delimitation of the motor-related areas that had significant activity. The results also showed continuous size reductions of the activated cluster in the motor cortex. The activation in the sensory cortex showed significant increases in cluster size over time. The intensity of both motor and sensory cortical activations correlated with the Disabilities of the Arm, Shoulder and Hand questionnaire. Our results show significant cortical reorganization of motor and sensory cortices after transplantation of bilateral forearm transplantation over a four-year period. PMID:26708028

    Background: Head and neck sarcomas are exceedingly rare and they include 4% - 10% of all sarcomas and less than 1% of all neoplasm of head and neck. Objectives: The aim of this study is to evaluate the epidemiological characteristics of head and neck sarcomas of patients in Isfahan, Iran. Patients and Methods: In this retrospective study, from the 16000 patients whose files were evaluated, the total number of 105 head and neck sarcomas were collected. They were evaluated with due attention to age, gender of the patients and the most common location of the lesion. Results: From the total number of 105 (0.6%) patients with sarcomas, 56 were men (53.33%) and 49 women (46.66%). The most common head and neck sarcomas among this population were Osteosarcoma (32 cases, 30.47%), Chondrosarcoma (14 cases, 13.33%), and Ewing sarcoma (11 cases, 10.47%).The most common soft tissue sarcoma was Rabdomiosarcoma. Mandible was the most common location for these lesions. Conclusions: In this study, the hard tissue sarcomas were more prevalent than soft tissue ones. Hence, special attention should be paid to the patients when being diagnosed. PMID:26478791

    2014-12-01

    The main objective of this study, which evaluated a sample of first-year students enrolled at the University of Burgundy, France, in 2010-2011, is to understand the factors determining success in the first year of university. The originality of this research lies in the inclusion of specific indicators of students' skills when they start university within the explanatory models of educational achievement. These indicators include measures of academic performance (written comprehension skills) and cognitive abilities. While the impact of cognitive abilities on educational success has been examined at primary level in France, the present study is among the first to do this at higher education level, with the additional consideration of students' educational and social backgrounds. The results show the significant impact of educational background (repeated years, type of baccalaureate and baccalaureate grade) on success. The researchers also found that written comprehension skills and cognitive abilities alone play a limited role in explaining success, since the impacts of these variables are apparent throughout a student's educational career (and not just in higher education). Another finding was that subject choice based on specific career aspirations is an important factor associated with success - a significant insight which qualifies the impact of educational background.

    Background: Oro-facial clefts are a major public health problem. Children with clefts rarely escape dental complications. Aims: This study was to determine differences in the dental caries experience, gingival health, and prevalence malocclusion, enamel defects and oral mucosal lesions among 4-6 year old children with and without cleft in Panchkula. Materials and Methods: The sampling frame consisted of 4-6 year old children with clefts visiting Swami Devi Dyal Hospital and Dental College, Panchkula, India. As a control group an age (±3 months) and gender-matched sample from the same geographical areas were recruited. Dental caries status, gingival health status, developmental defect of enamel, malocclusion and oral mucosal health were assessed and compared between the two groups. Results: Significant differences in dental caries and gingival health status were found between children with and without cleft. Anterior open-bite, increased overjet and oral mucosal lesions (P < 0.05) were more prevalent among children with clefts. Children with and without clefts had similar developmental defects of enamel (P > 0.05). Conclusion: Differences of oral health status exist among 4-6 year old children with and without clefts. Children fare worse in terms of dental caries, gingival health, oral mucosal health and malocclusion. PMID:25006561

    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. PMID:23896352

    AIM: Hepatitis C virus (HCV) infection is very common among end-stage kidney disease patients on hemodialysis, but its natural history is not known. METHODS: In this study, 189 dialysis patients (case) positive for HCV antibodies who were followed up for more than 4 years were compared with twice as many sex/age matched controls with chronic hepatitis C who were diagnosed in the same month as the case and followed up for comparable periods. The longest follow-up was 23 years in dialysis cases. The disease activities were graded into “asymptomatic” if ALT was less than 40 (35 in cases) IU/L, “low activities” if ALT was 40 (35)-79 IU/L, and “high activities” if ALT was above 80 IU/L during the last or latest 4 year period. RESULTS: All 25 dialysis cases who were followed up for more than 15 years were asymptomatic and 15 of them were negative for HCV RNA. Of the 50 controls followed up for more than 15 years, 34 had high activities, and none cleared HCV RNA. There were 60 controls who were asymptomatic, but they were all positive for HCV RNA, while 22.3% of asymptomatic dialysis cases were RNA negative. No dialysis patients with chronic hepatitis C progressed to cirrhosis, whereas the disease progressed to cirrhosis in more than one quarter of the controls. These differences were highly significant (P < 0.0001). CONCLUSION: Chronic hepatitic C among hemodialysis patients is mild in disease activity, and is not progressive, perhaps due to immunological abnormalities in these patients. Hepatic C virus is frequently cleared in asymptomatic dialysis patients during a long course. A possible mechanism for viral clearance is viral particle destruction on the surface of the dialyzer membrane. PMID:15259067

    Colorectal cancer is usually considered a disease of the elderly. However, a small fraction of patients develops colorectal cancer earlier. The aim of our study was to define the frequency of known hereditary colorectal syndromes and to characterise genetic and epigenetic features of early nonhereditary tumors. Thirty-three patients ≤40 years with diagnosis of colorectal cancer and 41 patients with disease at >60 years of age were investigated for MSI, Mismatch Repair proteins expression, KRAS and BRAF mutations, hypermethylation, and LINE-1 hypomethylation. Detection of germline mutations was performed in Mismatch Repair, APC and MUTYH genes. Early onset colorectal cancer showed a high incidence of hereditary forms (18%). KRAS mutations were detected in 36% of early nonhereditary tumors. Early onset colorectal cancer disclosed an average number of methylated genes significantly lower when compared to the controls (p = 0.02). Finally both of the two groups were highly methylated in ESR1, GATA5, and WT1 genes and were similar for LINE-1 hypomethylation. The genetic make-up of carcinomas differs from young to elderly patients. Early onset tumors showed more frequently a constitutional defective of Mismatch Repair System and a minor number of methylated genes. Hypermethylation of ESR1, GATA5, and WT1 genes suggests possible markers in the earlier diagnosis of colorectal tumorigenesis. PMID:26557847

    Botulinum toxin A (BTA) is a recognized treatment for the early management of spasticity in children with Cerebral Palsy. This study quantified with Gait Analysis (GA) the gait pattern of a 4-year-old diplegic child with calf contracture before, 5 days, and 3 months after BTA injections into gastrocnemius. Kinematic and kinetic data of main lower limb joints were investigated. After only 5 days, ankle dorsi-plantarflexion and knee flex-extension improved, but hip joint worsened, increasing its excessive flexion, to compensate the improvement in knee position of the treated limb and to obtain better stability. A worsening of hip power happened. After 3 months, all joints generally improved their position during gait cycle. Hip and knee joints increased their range of movement and improvements occurred at ankle kinematics and kinetisc, too; a better ankle position and an increase of its capacity of propulsion during terminal stance were evident.

    Ocular Trauma is an important cause of monocular visual impairment and blindness in younger age groups. We examined the cases of hospitalized ocular trauma from 1st January, 1985 through 30th July, 1990 using hospital medical records. The study comprised 27 patients (28 eyes), 51.8% of whom were under 16. The male-female ratio was 2.8:1. Right eye was more commonly involved (66.6%) and one patient had bilateral ruptured globes. Children at play were most vulnerable (33.3%) followed by road accidents which was the major cause (29.6%) in adults. Sixteen (64.0%) eyes suffered some complications and their mean duration of presentation after injury was 28.4 hours. Traumatic cataract was the most common complication (50.0%) in this group, followed by vitreous haemorrhage (37.5%). Nine (36%) ocular injuries did not develop any complications and presented 14 hours (average) after injury. Most of the patients retained their vision on follow-up examination, but 16.0% lost their vision completely. Another 3 eyes had to be enucleated due to severe trauma and loss of vision. PMID:1942481

    Background A cross-sectional study has reported that nickel allergy is associated with endometriosis. However, causal studies of this association are limited. Objective The objective of this study was to compare the prevalence of nickel allergy in women with and without endometriosis. Methods We used a National Health Insurance Service (NHIS) sample cohort dataset that included approximately 1 million individuals from South Korea; the data were obtained between January 01, 2002, and December 31, 2013. We selected the endometriosis group according to diagnosis code (N80.X), surgery codes, and drug codes during the years 2009~2013. The controls were randomly matched to the endometriosis patients at a ratio of 4:1 by age and socioeconomic status. Patients with nickel allergy were defined in the cohort dataset as those with a simultaneous diagnosis code (L23.0) and patch test code during 2002~2008. Results In total, 4,985 women were selected from the NHIS cohort database and divided into an endometriosis group (997 women) and a control group (3,988 women). The number of patients with nickel allergy in the endometriosis group was eight (0.8%), and that in the control group was thirteen (0.3%). After adjustment for age and socioeconomic status, the rate of nickel allergy in was higher in the endometriosis group than in the control group [odds ratio: 2.474; 95% confidence interval: 1.023~5.988; p = 0.044]. Conclusions We found that nickel allergy is a risk factor for endometriosis. PMID:26439741

    Children with communication disorders present with a range of comorbid conditions. Occasionally one of the comorbid conditions manifests so strongly that the primary condition goes unnoticed by the clinician. This tendency to overlook comorbid health problems in the presence of a disability is referred to as diagnostic overshadowing. This is a five-year follow up case study of a 9-year-old female child. The child was initially diagnosed to have Separation anxiety disorder (SAD), but during the course of follow up she began to exhibit features of pervasive developmental disorder-not otherwise specified (PDD-NOS). This case report throws light on the severity of SAD which overshadowed PDD-NOS. Importance of follow-up and the need for a multidisciplinary team to be sensitive to the phenomenon of diagnostic overshadowing is discussed. PMID:23108987

  14. Exceptions to the rules of oil-spill behavior: Case studies of major oil spills of the past twenty years

    SciTech Connect

    Hayes, M.O.

    1994-11-01

    Studies of major oil spills over the past 20 yr have allowed an evolution of our understanding of how to respond to and remediate the environmental impacts from such spills. There have been a number of spills for which follow-up research has provided major turning points that allowed the development of certain rules of oil-spill behavior. For example, the spill of over 100,000 tons of crude oil by the tanker Urquiola on the coast of Spain in May 1976 demonstrated the importance of hydrodynamic energy level in natural cleanup processes. Research on the spill of over 200,000 tons of crude oil along the coast of France by the tanker Amoco Cadiz in March 1978 allowed a better understanding of the long-term effects of spilled oil on exposed tidal flats and salt marshes. The oil spilled by the tanker Exxon Valdez in Prince William Sound, Alaska, in March 1989 impacted many miles of gravel beaches, which were treated by a number of methods, including some innovative berm-relocation techniques. A thorough understanding of the coastal geomorphology and processes of the spill site was essential for the development of meaningful contingency and response plans. Research on the impacts of intertidal habitats of the coast of Saudi Arabia during the Gulf War spill of 1991 indicates that some previously held concepts on oil behavior and fate on shorelines must be revised. One of the best established rules of oil-spill behavior was that the depth of oil penetration on sand beaches and tidal flats increases with increasing sediment grain size. However, no such correlation was found on the Saudi Arabian coast, primarily due to the presence of secondary porosity (e.g., bubble sand, extensive burrows, and gypsum crystals). The oil penetrated to depths of tens of centimeters, even in fine sand, which has significantly slowed natural removal processes and weathering rates. These sediments remained heavily oiled with incipient asphalt pavements forming two years after the spill.

    The use of simulation as a teaching strategy in undergraduate nursing education is gaining increasing credibility and popularity. This article describes a study undertaken to evaluate first-year undergraduate nursing students' level of satisfaction with a new model of teaching clinical skills using unfolding case studies in a high-fidelity simulated clinical setting. The design incorporated a case study design conducted over 4 × 6 h simulation sessions. Participants included 47 first year Bachelor of Nursing Science students, three academic staff and two standardised patients. Findings from the study provide qualitative and quantitative evidence to support a high fidelity simulated model of teaching clinical skills development for first year undergraduate nursing students. High positive scores in all sections of the student survey provide quantitative evidence of student's satisfaction with all elements of the teaching model and qualitative data from interviews supporting this claim. Additionally, analysis of interview data provides qualitative evidence to support the value of the learning experience for students and academics, and students desire to participate more frequently in simulation sessions.

    A retrospective case-control study of patients who had undergone cataract extraction at a Spanish hospital over a 13-year period was conducted to identify the risk factors for developing post-operative endophthalmitis (POE). During the study period, the type of antibiotic prophylaxis was changed from subconjunctival gentamicin to the addition of both vancomycin and gentamicin to the irrigating solution. The overall incidence of POE was 0·19% (35 cases/18 287 operations). For the period prior to the change in antibiotic prophylaxis, the incidence rate of POE was 3·4 cases/1000 operations while in the latter period the incidence rate decreased to 0·34 cases/1000 operations. All patients who presented a virulent microorganism had a final visual acuity worse than 20/200. The only significant risk factor identified was the type of prophylaxis used (odds ratio 1·97, 95% confidence interval 0·94-4·14, P = 0·07). There were no significant differences between cases and controls although choice of surgeon approached significance. PMID:24612657

    Melanotic or melanocytic schwannoma is a rare tumour usually involving spinal nerve roots but can also present at other anatomical locations. Although there are less than 200 cases reported, melanotic schwannomas can have distinctive imaging features but there is limited recent literature on its often characteristic radiological appearances. Recent publication of the largest case series thus far has suggested melanotic schwannoma to be a separate entity to other schwannomata and that its reclassification to a malignant lesion be under consideration. We present a case series over an 11-year period to highlight salient imaging features with reference to the current concerns regarding its malignant potential. PMID:26386847

    Aim To investigate risk factors for first long-bone fractures in children up to 5 years old in order to provide evidence about which families could benefit from injury prevention interventions. Methods Population-based matched nested case–control study using The Health Improvement Network, a UK primary care research database, 1988–2004. Maternal, household and child risk factors for injury were assessed among 2456 children with long-bone fractures (cases). 23?661controls were matched to cases on general practice. Adjusted ORs and 95% CIs were estimated using conditional logistic regression. Results Fractures of long-bones were independently associated with younger maternal age and higher birth order, with children who were the fourth-born in the family, or later, having a threefold greater odds of fracture compared to first-born children (adjusted OR 3.12, 95% CI 2.08 to 4.68). Children over the age of 1?year had a fourfold (13–24?months, adjusted OR 4.09 95% CI 3.51 to 4.76) to fivefold (37+ months, adjusted OR 4.88 95% CI 4.21 to 5.66) increase in the odds of a long-bone fracture compared to children aged 0–12?months. Children in families with a history of maternal alcohol misuse had a raised odds of long-bone fracture (adjusted OR 2.33, 95% CI 1.13 to 4.82) compared to those with no documented history. Conclusions Risk factors for long-bone fractures in children less than 5 years old included age above 1?year, increasing birth order, younger maternal age and maternal alcohol misuse. These risk factors should be used to prioritise families and communities for injury prevention interventions. PMID:25398446

    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. PMID:24620951

    The relationships among veterinary students' approaches to learning, perceptions of the teaching-learning environment, and study success were evaluated in a demanding, discipline-based curriculum. The aim was to elicit elements for improving student counseling. As part of a large multidisciplinary survey, 36 third-year students (74% response rate) answered a modified version of the Experiences of Teaching and Learning Questionnaire in 2006. In this study, the authors used students' responses to questions regarding examinations and the progress of studies. In addition, students were classified in the large survey into four clusters according to their approaches to studying. Study success was evaluated by exploring the number of study credits students had earned and their grade point averages. The differences in study success between the clusters were not statistically significant, but, in general, students applying a deep approach were most successful, whereas unorganized students applying a deep approach showed the largest variation in study progress. The most commonly mentioned factors for enhancing or impeding study progress were related to the curriculum and to the students' actions or experiences. Unorganized students applying a deep approach seemed to suffer the most from the workload and pressure of progressing in their studies according to a predetermined timetable. These students were also most unaware of the examinations' demands. The findings suggested that, in addition to curriculum development, there is a need to explicitly make students aware of their approaches to learning and to support the development of their study practices.

    Mutations in the glucocerebrosidase gene (GBA1) cause Gaucher disease (GD) and are the most common genetic risk factor for the development of Parkinson's disease (PD). Here, we present a 12-year follow-up study of a male with GD and PD (diagnosed 24years ago), which PD preceded the clinical manifestation of GD by 12years. The patient is a compound heterozygote for mutations c.115+1G>A and c.1226A>G (IVS2 + 1/N370S) in the GBA1 gene. Imiglucerase had a beneficial effect on GD, but not on PD. Treatment with L-dopa and other PD drugs showed temporary efficacy but 2years later significant wearing-off phenomenon and dyskinesias appeared. Unilateral pallidotomy was performed with transient benefit. Cognitive decline appeared later and developed in to akinetic mutism. A lumbar puncture was performed to characterize the biochemical profile of cerebrospinal fluid (CSF). Analyses of monoamine metabolites levels in the CSF, determined by reverse-phase high-performance liquid chromatography, revealed remarkably low levels of all studied monoamine metabolites (HVA, DOPAC, 5-HIAA, MHPG). These data indicate that PD associated with GBA1 mutations may not only affect dopaminergic neurons, but also noradrenergic and serotonergic neurons. Of note, normal levels of P-tau, total tau and ?-amyloid (1-42) were detected on ELISA assay. Thus, the cognitive decline, akinetic mutism and moderate cortical atrophy found on the CT scan were not paralleled by any changes of dementia markers in CSF. This single case study extends the follow-up period and adds novel CSF information; however additional data on other patients with both PD and GD may help put our observations in its ultimate proper context.

    Background There are very limited data on children with pneumonia in Mali. The objective was to assess the etiology and factors associated with community-acquired pneumonia in hospitalized children <5 years of age in Mali. Methods A prospective hospital-based case-control study was implemented in the Pediatric department of Gabriel Touré University Hospital at Bamako, Mali, between July 2011-December 2012. Cases were children with radiologically-confirmed pneumonia; Controls were hospitalized children without respiratory features, matched for age and period. Respiratory specimens, were collected to identify 19 viruses and 5 bacteria. Whole blood was collected from cases only. Factors associated with pneumonia were assessed by multivariate logistic regression. Results Overall, 118 cases and 98 controls were analyzed; 44.1% were female, median age was 11 months. Among pneumonia cases, 30.5% were hypoxemic at admission, mortality was 4.2%. Pneumonia cases differed from the controls regarding clinical signs and symptoms but not in terms of past medical history. Multivariate analysis of nasal swab findings disclosed that S. pneumoniae (adjusted odds ratio [aOR] = 3.4, 95% confidence interval [95% CI]: 1.6–7.0), human metapneumovirus (aOR = 17.2, 95% CI: 2.0–151.4), respiratory syncytial virus [RSV] (aOR = 7.4, 95% CI: 2.3–23.3), and influenza A virus (aOR = 10.7, 95% CI: 1.0–112.2) were associated with pneumonia, independently of patient age, gender, period, and other pathogens. Distribution of S. pneumoniae and RSV differed by season with higher rates of S. pneumoniae in January-June and of RSV in July-September. Pneumococcal serotypes 1 and 5 were more frequent in pneumonia cases than in the controls (P = 0.009, and P = 0.04, respectively). Conclusions In this non-PCV population from Mali, pneumonia in children was mainly attributed to S. pneumoniae, RSV, human metapneumovirus, and influenza A virus. Increased pneumococcal conjugate vaccine coverage in children could significantly reduce the burden of pneumonia in sub-Saharan African countries. PMID:26696249

  13. Scaling up specialist training in developing countries: lessons learned from the first 12 years of regional postgraduate training in Fiji – a case study

    PubMed Central

    2012-01-01

    Background In 1997, regional specialist training was established in Fiji, consisting of one-year Postgraduate Diplomas followed by three-year master’s degree programs in anesthesia, internal medicine, obstetrics/gynecology, pediatrics and surgery. The evolution of these programs during the first 12 years is presented. Case description A case study utilizing mixed methods was carried out, including a prospective collection of enrolment and employment data, supplemented by semi-structured interviews. Between 1997 and 2009, 207 doctors (113 from Fiji and 94 from 13 other countries or territories in the Pacific) trained to at least the Postgraduate Diploma level. For Fiji graduates, 29.2% migrated permanently to developed countries, compared to only 8.5% for regional graduates (P <0.001). Early years of the program were characterized by large intakes and enthusiasm, but also uncertainty. Many resignations took place following a coup d’etat in 2000. By 2005, interviews suggested a dynamic of political instability initially leading to resignations, leading to even heavier workloads, compounded by academic studies that seemed unlikely to lead to career benefit. This was associated with loss of hope and downward spirals of further resignations. After 2006, however, Master’s graduates generally returned from overseas placements, had variable success in career progression, and were able to engage in limited private practice. Enrolments and retention stabilized and increased. Discussion and evaluation Over time, all specialties have had years when the viability and future of the programs were in question, but all have recovered to varying degrees, and the programs continue to evolve and strengthen. Prospective clarification of expected career outcomes for graduates, establishment of career pathways for diploma-only graduates, and balancing desires for academic excellence with workloads that trainees were able to bear may have lessened ongoing losses of trainees and graduates. Conclusions Despite early losses of trainees, the establishment of regional postgraduate training in Fiji is having an increasingly positive impact on the specialist workforce in the Pacific. With forethought, many of the difficulties we encountered may have been avoidable. Our experiences may help others who are establishing or expanding postgraduate training in developing countries to optimize the benefit of postgraduate training on their national and regional workforces.

    Background Tetanus still remains a major public health problem in India like in most other developing countries, with a high morbidity and mortality. Objectives To study the socio-demographic profile and the clinical profile that they presented with, as well as the outcome of the tetanus patients who were admitted to the E.D Hospital, Mysore in India. Methodology The data of all the patients of tetanus who were above the age of 15 years, who were admitted from January 2001 to December 2010, were collected, compiled and analyzed from the Medical Records Department of the Hospital. Results Out of the 512 cases of tetanus, 379 (74%) were males and 133 (26%) were females. Their ages varied from 15 to 81 years, with a mean and a standard deviation respectively of 47.7 and 15.0 years. The overall mortality rate was 42.2%. The most common presenting symptoms were trismus (95.7%), neck stiffness (89.3%), body spasms/stiffness (73%) and dysphagia (38.9%). The ages of the patients and the presence of complications had a statistically significant relationship with respect to the outcome (survival versus death). PMID:23205351

    2016-01-01

    Background: Hereditary hemoglobin (Hb) disorders are the most commonly encountered single gene disorders in India. Proper timely identification of these disorders is of paramount importance to prevent thalassemia major and clinically severe hemoglobinopathy as well as for epidemiologic purposes. Aims: Our aim was to determine the prevalence of thalassemia and hemoglobinopathy in patients of a tertiary care hospital of West Bengal, India. Materials and Methods: This prospective study was conducted on 119,336 cases over a period of 10 years. After taking clinical history and familial history, complete hemogram report was obtained by an automated cell counter. High-performance liquid chromatography (HPLC) was performed on the samples with Bio-Rad Variant using beta thalassemia short program. Confirmatory tests were performed whenever required. Results: A normal Hb pattern was observed in 104,804 (87.83%) cases and abnormalities were detected in 14,532 (12.17%) patients. β (beta) thalassemia trait was the commonest abnormality found in 5,488 (4.60%) patients. HbE trait was found in 3,604 (3.02%) patients, β thalassemia major/intermedia in 1,981 (1.66%) cases, and Eβ thalassemia in 1,384 (1.16 %) cases. Other variants detected included HbE disease, sickle-cell disease, sickle β thalassemia, HbD-Punjab trait, HbQ-India trait, α-thal trait, double heterozygous state of HbS and HbE, double heterozygous state of HbS and HbD, HbJ-Meerut, hereditary persistence of fetal hemoglobin (HPFH), HbH, delta β-thal trait, and Hb Lepore. Conclusion: In view of the high prevalence of hemoglobinopathy in this region, a routine premarital screening program is needed for the identification and prevention of high-risk marriages and thus, prevention of the psychosocial trauma of bearing a transfusion-dependent child for life.

    Background?Screw fixation and bone grafting are the gold standard for scaphoid waist nonunion without avascular necrosis. Question/Purpose?Assesses the scaphoid waist nonunion healing rate with use of an uncommon cancellous bone graft (olecranon) and an unusual fixation system (Asnis Micro Cannulated Screw System; Stryker Inc., Kalamazoo, MI, USA). Material and Methods?A series of 102 consecutive patients were treated for scaphoid waist nonunion (without deformity). Of these, 80 patients subjected to clinical (Modified Mayo Wrist Score (MMWS), Jamar hydraulic dynamometer) and radiographic examination before and after surgery were evaluated. Ipsilateral olecranon cancellous bone graft and the ASNIS Micro 3.0-mm diameter screw, were used. The average follow up was 6 years (min 3; max 10). Results?Radiographic consolidation was achieved in 90% of patients; dorsal intercalated segment instability (DISI) deformities were corrected in 71.4% of cases. Ninety percent improved the range of motion of the wrist and grip strength. All patients showed a significant reduction of peak force in the operated hand. In 6.25% we observed clinical and radiographic screw head-trapezium impingement. Twenty-six patients developed a degenerative wrist sign. The MMWS yielded 68 optimal, 8 good, and 4 bad results. Conclusions?To treat scaphoid waist nonunions without misalignment, low-profile headed screw and olecranon bone graft allowed a high consolidation rate with positive results to long-term follow-up. The Asnis Micro 3.0 mm diameter screw may be a suitable option for treating scaphoid waist nonunion. Level of Evidence?IV. PMID:26261746

  17. The case study approach

    PubMed Central

    2011-01-01

    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

  18. Enhanced physical health screening for people with severe mental illness in Hong Kong: results from a one-year prospective case series study

    PubMed Central

    2014-01-01

    Background People with severe mental illness have significantly poorer physical health compared to the general population; previous health screening studies conducted outside Asian countries have demonstrated the potential in addressing this issue. This case series aimed to explore the effects and utility of integrating an enhanced physical health screening programme for community dwelling patients with severe mental illness into routine clinical practice in Hong Kong. Method This study utilises a consecutive prospective case series design. The serious mental illness Health Improvement Profile (HIP) was used as a screening tool at baseline and repeated at 12 months follow-up. Results A total of 148 community-based patients with severe mental illness completed the study. At one year follow-up analysis showed a significant improvement in self-reported levels of exercise and a reduction in the numbers of patients prescribed medications for diabetes However, mean waist circumference increased at follow-up. In addition to the statistically significant results some general trends were observed, including: a lack of deterioration in most areas of cardiovascular risk; a reduction in medicines prescribed for physical health problems; and general improvements in health behaviours over the 12 month period. Conclusions The findings demonstrate that using the HIP is feasible and acceptable in Hong Kong. The results of the enhanced physical health-screening programme are promising, but require further testing using a randomised controlled trial design in order to more confidently attribute the improvements in well-being and health behaviours to the HIP.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    2016-02-01

    This study compared the effects of different dosages of intravenous immunoglobulin (IVIg) against immune thrombocytopenia (ITP). A total of 167 patients, 91 adults and 76 children, with ITP, followed-up for three years in the case-control study, were divided into three subgroups according to the dosages of IVIg administered: group A (0.2 g/kg/day), group B (0.3 g/kg/day) and group C (0.4 g/kg/day). The therapeutic response in 91 adult patients did not differ significantly among the three groups of IVIg dosages (p = 0.459). The response rate of IVIg treatment in the three adult groups was 97.1% for group A, 97.2% for group B and 100% for group C. The mean time for raising platelets to 30 × 10(9)/L in group A was 2.5 days, group B 3.2 days and group C 2.9 days (p = 0.324). The median IVIg consumption in group A was 0.83 g/kg, group B 1.22 g/kg and group C 1.64 g/kg (p < 0.01). Similar results were shown in the children groups. The follow-up results showed no significant difference of clinical outcome between groups A, B and C. In conclusion, low-dose IVIg treatment is shown to be as effective as high-dose regimen without increasing the risk of developing the patients into chronic ITP conditions, suggesting that ITP patients could be treated more cost-effectively by lower conventional dosage of IVIg regimen.

    PubMed

    Friedberg, Ahron L

    2015-12-01

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    A retrospective study was undertaken of all cases of death due to suicidal electrocution in Sydney, Australia between 1996 and 2005. A total of 25 cases were identified with 20 cases (80%) as a result of direct attachment to an electrical outlet and five cases (20%) as a result of immersion in a body of water with an electrical appliance. Twenty of the 25 individuals were men (mean age = 57 years, range 22-90) and five were women (mean age 67, range 53-88). At least 35% of decedents were either currently working or had worked as electricians. Electrical timers had been used in eight (32%) cases, the fuse blown in one case, but the remaining 16 (64%) bodies were "live" on arrival of witnesses or electricity personnel. This study demonstrates the phenomenon of electrical suicide as a regular occurrence in Sydney. We highlight the need for investigators and emergency workers to remain vigilant upon discovery of electrical suicides, due to the fact that most bodies remain electrically active after death.

    We report a case of a 33-year-old woman with emergency admission due to dyspnoea and fever. History included squamous cell carcinoma of the cervix in complete remission. Contrast-enhanced computed tomography (CT) scanning of the chest, which was indicated to rule out pneumonia, revealed an infiltrative cardiac mass. Further assessment of the tumour by echocardiography and cardiac magnetic resonance imaging (MRI) showed transmural infiltration of the apical interventricular septum with a mass extending into the left and right ventricle cavities. The mass was highly suspicious for a cardiac metastasis. Cardiac metastases from cervical cancer are extremely rare. Recurrence of cervical carcinoma involving the heart should be considered even after a curative therapy approach. Non-invasive imaging plays a paramount role in investigating cardiac masses. Echocardiography, CT and MRI are complementary imaging modalities for complete work-up of intracardiac lesions. PMID:25346849

    Acute interstitial pneumonitis (AIP), also known as Hamman-Rich syndrome, is a distinct type of idiopathic interstitial pneumonia affecting patients of both genders without pre-existing lung diseases. We describe the case of a fulminant form of AIP and discuss the pathophysiological mechanisms of AIP with reference to the histological pattern. A 15-year-previously-healthy male boy presented to the Hospital with a 6-day history of malaise, fever and cough. The clinical prodromes were followed by the acute onset of increasing shortness of breath rapidly progressing in acute respiratory failure. Chest X-ray demonstrated bilateral diffuse airspace opacification; the high resolution CT confirmed the presence of bilateral, symmetric diffuse ground-glass attenuation. The patient was admitted to the intensive care unit, but died after few hours. An autopsy was performed within 24h. The histological examination of lung specimens showed a pattern of diffuse alveolar damage. immunohistochemical, microbiological and toxicological tests were also carried out. The clinical presentation, the histological findings and the exclusion of infective, traumatic, toxic and metabolic causes of acute respiratory distress syndrome (ARDS) allowed us to conclude that the boy was affected by AIP. In conclusion, AIP is a diagnosis of exclusion. It has a mortality rate ranging about 50%, despite mechanical ventilation. In fatal cases of AIP diagnosis can be based on clinical presentation, radiological, histological and microbiological findings and can be further confirmed by immunohistochemical analysis.

    Warden, Stuart J.; Mantila Roosa, Sara M.

    2014-01-01

    Physical activity is recommended for skeletal health because bones adapt to mechanical loading. The young skeleton shows greatest plasticity to physical activity-related mechanical loads, but bones are most at risk of failure later in life. The discrepancy raises the question of whether the skeletal benefits of physical activity completed when young persist with aging. Here we present a unique case wherein the cortical bone benefit of physical activity completed over five decades earlier could be established within an individual aged in their tenth decade of life. Specifically, we compared bone properties at the midshaft humerus between the throwing and nonthrowing arms of a 94-year-old former Major League Baseball player who ceased throwing 55 years earlier. By performing analyses within-subject, the long-term skeletal benefit of physical activity completed when young could be assessed independent of inherited and systemic traits. Also, as the subject threw left-handed during his throwing career, but was right-hand dominant in all other activities throughout life, any lasting skeletal benefits in favor of the throwing arm could not be attributable to simple arm dominance. Analyses indicated that any cortical bone mass, area and thickness benefits of throwing-related physical activity completed when young were lost with aging, possibly due to accelerated intracortical remodeling. In contrast, the subject’s throwing (nondominant) arm had greater total cross-sectional area and estimated strength (polar moment of inertia) than in his dominant arm, despite muscle indices favoring the latter. These data indicate that physical activity completed when young can have lasting benefits on bone size and strength, independent of the maintenance of bone mass benefits. PMID:24879028

    2012-12-01

    This paper presents a qualitative case analysis of a new and unique, high school, student-directed, project-based learning (PBL), virtual reality (VR) class. In order to create projects, students learned, on an independent basis, how to program an industrial-level VR machine. A constraint was that students were required to produce at least one educational application of VR. This study incorporated in-depth classroom observations, interviews with students, analyses of student projects, and surveys of parents and teachers to examine the social and learning processes in the class, and the nature of content learning represented in student projects. The results demonstrated that PBL can be effective even with minimal teacher guidance. The findings substantiate an educational approach rich with promise, for at least some students, that deserves considerable additional study to maximize its powerful potentials for independent and peer-mentored learning.

    The aim of this study was to determine the efficacy of The Listening Program (TLP) in treating a child with pervasive developmental disorder-not otherwise specified (PDD-NOS). Using a single-subject case study design, one child with PDD-NOS was administered a 20-week TLP intervention focused on improving sensory processing and language function. Data collection included pre- and post-evaluations using video footage, and Sensory Profile and Listening Checklist questionnaires. Results of the study indicated improved behaviour and sensory tolerance in the post-intervention video footage, including active participation in singing and movements to song. Sensory Profile and Listening Checklist questionnaires indicated significant improvements in sensory processing, receptive/expressive listening and language, motor skills, and behavioural/social adjustment at the post-intervention assessment. Although small in scope, this study highlights the need for continued research by occupational therapists into sound-based interventions. Particularly, occupational therapists need to perform larger-scale studies utilizing TLP to verify the efficacy of this alternative treatment method. PMID:19222056

    This paper aims to monitor desertification evolution of different stages and assess its factors using remote sensing (RS) data and cellular automata (CA)-geographical information system (GIS) with an adaptive analytic hierarchy process (AHP) to derive weights of desertification factors. The study areas (114°E to 117°E and 39.5°to 42.2°N) are one of the important agro-pastoral transitional zone, located in Beijing and its neighboring areas, marginal desertified areas in North China. Desertification information including NDVI and desertification area were derived from the satellite images of 1987TM, 1996TM (with a resolution of 28.5), and 2006 CBERS-(with a resolution of 19.5 m) in study areas. The ancillary data in terms of meteorology, geology, 30m-DEM, hydrography can be statistical analyzed with GIS technology. A CA model based on the desertification factors with AHP-derived weights was built by AML program in ArcGIS workstation to assess the evolution of desertification in different stages (from 1987 to 1996, and from 1996 to 2006). The research results show that desertified areas was increased by 3.28% per year from 1987 to 1996, so was 0.51% per year from 1996 to 2006. Although the weights of desertification factors have some changes in different stages, the main factors including climate, NDVI, and terrain did not change except the values in study areas.

    Background Migraine aura may be difficult to differentiate from transient ischemic attacks and other transient neurological disorders in pregnant women. The aims of the present study were to investigate and diagnose all pregnant women with transient neurological disorders of suspected central nervous system origin, and to compare this group with a control group of pregnant women with regard to vascular risk factors and prognosis. Methods During a 28 month period, 41 patients were detected with transient neurological symptoms during pregnancy. These were studied in detail with thorough clinical and laboratory investigations in order to make a certain diagnosis and to evaluate whether the episodes might be of a vascular nature. For comparison, the same investigations were performed in 41 pregnant controls. To assess the prognosis, both patients and controls were followed with questionnaires every year for five years. Results Migraine with aura was the most common cause of symptoms during pregnancy, occurring in 34 patients, while 2 were diagnosed with stroke, 2 with carpal tunnel syndrome, 1 with partial epilepsy, 1 with multiple sclerosis and 1 with presyncope. Patients had more headache before pregnancy than controls, but the average levels of vascular risk factors were similar. None of the patients or the controls reported cerebrovascular episodes during the five-year follow-up. Conclusion The diagnosis of migraine aura was difficult because for many patients it was their first ever attack and headache tended to be absent or of non-migraineous type. The aura features were more complex, with several aura symptoms and a higher prevalence of sensory and dysphasic aura than usual. Gradually developing aura symptoms, or different aura symptoms occurring in succession as described in the International Classification of Headache Disorders, seem to be useful for differentiating aura from other transient disorders. A meticulous history and clinical neurological examination are more useful than routine supplementary investigations for cerebrovascular disease. The five-year follow-up clearly indicates that migraine with aura in pregnancy usually has a good prognosis with regard to cerebrovascular events. PMID:17640340

    In recent educational research, it is well acknowledged that gestures are an important source of developing abstract thinking in early childhood and can serve as an additional window to the mind of the developing child. The present paper reports on a case study which explores the function of gestures in a geometrical activity at kindergarten level. In the study, the spontaneous gestures of the child are investigated, as well as the influence of the teacher's gestures on the child's gestures. In the first part of the activity, the child under study transforms a spatial array of blocks she has constructed by herself into a verbal description, so that another person, i.e., the teacher, who cannot see what the child has built, makes the same construction. Next, the teacher builds a new construction and describes it so that the child can build it. Hereafter, it is again the turn of the child to build another construction and describe it to the teacher. The child was found to spontaneously use iconic and deictic gestures throughout the whole activity. These gestures, and primarily the iconic ones, helped her make apparent different space and shape aspects of the constructions. Along with her speech, gestures acted as semiotic means of objectification to successfully accomplish the task. The teacher's gestures were found to influence the child's gestures when describing aspects of shapes and spatial relationships between shapes. This influence results in either mimicking or extending the teacher's gestures. These findings are discussed and implications for further research are drawn.

    In this article, we discuss the impact of migration and acculturation processes on the cultural, personal identity, and mental health of children who immigrate to a Western, multicultural environment, and the challenges clinicians in such environments face, when confronted with non-Western idioms of distress and healing practices. We do that by presenting a challenging clinical case of an 8-year-old girl who presented with very disorganized behavior, which matches a culturally accepted construct of spirit possession, in the context of migration trauma, acculturative stress, and new sibling transition. We identify cultural conflict in school and bullying as major mediators between acculturative stress and mental distress. We also aim at identifying vulnerability, risk and protective factors, and the importance of cultural coping resources. We explore in depth the patient's cultural background and the family's belief system and culturally shaped narratives, in order to arrive at a cultural formulation, which focuses on the significance of idioms of distress in shaping psychopathology and influencing the personal and interpersonal course of trauma- and stress-related disorders. We also call attention to the finding that in children, idioms of distress may manifest themselves in a somatic manner. We argue, together with other researchers, that spirit possession deserves more interest as an idiom of distress and a culture-specific response to traumatizing events. We finally emphasize the importance of an anti-reductionist clinical stance, that is able to use different levels of understanding processes of distress and healing, and seeks to reconciliate cultural divides and integrate different explanatory frameworks and help-seeking practices.

    Purpose A colonoscopic polypectomy is an important procedure for preventing colorectal cancer, but it is not free from complications. Delayed hemorrhage after a colonoscopic polypectomy is one infrequent, but serious, complication. The aim of this study was to identify the risk factors for delayed hemorrhage after a colonoscopic polypectomy. Methods This was a retrospective case-control study based on medical records from a single gastroenterology center. The records of 7,217 patients who underwent a colonoscopic polypectomy between March 2002 and March 2012 were reviewed, and 92 patients and 276 controls were selected. Data collected included comorbidity, use of antiplatelet agents, size and number of resected polyps, histology and gross morphology of resected polyps, resection method, and use of prophylactic hemostasis. Results The average time between the procedure and bleeding was 2.71 ± 1.55 days. Univariate and multivariate analyses revealed that the size of the polyps was the only and most important predictor of delayed hemorrhage after a colonoscopic polypectomy (odds ratio, 2.06; 95% confidence interval, 1.12-1.27; P = 0.03). Conclusion The size of resected polyps was the only independent risk factor for delayed bleeding after a colonoscopic polypectomy. The size of a polyp, as revealed by the colonoscopic procedure, may aid in making decisions, such as the decision to conduct a prophylactic hemostatic procedure. PMID:25210687

    Introduction: The role of the conventional risk factors in premature coronary artery disease (CAD) after eliminating the confounding variability of smoking has not been evaluated. This study was conducted to identify role of traditional risk factors in smokers with premature CAD. Methods: The case records of patients presenting acutely with premature CAD during the period 2007-2010 were analyzed retrospectively. Age, sex and smoking matched controls were selected from same time period. Data records were obtained for family history, alcohol, waist size, blood pressure, hypertension, blood sugar, lipid profile and presence of cutaneous markers for both groups and analyzed using statistical software. Results: 234 smokers with CAD and 122 smokers without CAD were included in groups 1 and 2, respectively. The patients in group 1 had significantly increased prevalence of hypertension, diabetes mellitus, metabolic syndrome, dyslipidemia and central obesity. There was no difference in prevalence of family history of CAD, arcus juvenilis and baldness. We found statistically significant association of hypertension, DM and metabolic syndrome in young smokers with premature acute CAD in Indian population as compared to young smokers without CAD. Conclusion: In young smokers, presence of hypertension, central obesity, diabetes mellitus and metabolic syndrome identifies a subset at increased risk for future acute CAD requiring more rigorous follow up and treatment.

    Polycyclic aromatic hydrocarbon (PAH) atmospheric deposition was evaluated at a remote site in Northern Spain using moss biomonitoring with Hylocomium splendens (Hedw.) Schimp., and by measuring the total deposition fluxes of PAHs. The year-long study allowed seasonal variations of PAH content in mosses to be observed, and these followed a similar trend to those of PAH fluxes in total deposition. Generally, atmospheric deposition of PAHs is greater in winter than in summer, due to more PAH emissions from domestic heating, less photoreactivity of the compounds, and intense leaching of the atmosphere by wet deposition. However, fractionation of these molecules between the environmental compartments occurs: PAH fluxes in total deposition and PAH concentrations in mosses are correlated with their solubility (r=0.852, p<0.01) and lipophilic properties (KOW, r=0.768, p<0.01), respectively. This annual study therefore showed that atmospheric PAH fluxes can be estimated with moss biomonitoring data if the bioconcentration or 'enriching' factors are known. PMID:25084064

    By analysing the sampled data and the results of the second national soil survey by the mid 80 s in Zhuanglang County, the article studied on the changes and influencing factors of the soil organic carbon in farmland of this area in the last 30 years. Farmland samples of top soil (0-20 cm) were collected and analyzed in July 2011. The results showed that (1) The average contents of the soil organic carbon in the county's farmlands were 6.80 g x kg(-1) in 1985 and 8.90 g x kg(-1) in 2011. It increased by 30.9% in the past 30 years, which appeared as a carbon sink effect. The area of increasing contents of soil organic carbon accounted for about 90% of the county's farmland area. (2) Under the available management measures and farmland input, the loessal soil organic carbon stability level was 11.0 g x kg(-1), The SOC accumulation rate showed that the farther the SOC was from the stability level the more quickly it changed, and the closer the SOC was from the stability level the slower it changed. (3) The SOC changes was affected by the altitude, the primary content of organic carbon, and the soil types and so on, in which the greatest contribution factor was the altitude, the influence of the primary content of organic carbon, soil type, production and organic fertilizer on soil organic carbon change was smaller, and the slope aspect had the smallest effect on soil organic carbon change.

    Background Studies have documented the short-term vascular benefits of combination lipid therapy. Objective Our objective was to evaluate the long-term effects of combination lipid therapy on carotid intima-media thickness (CIMT) in patients with coronary artery disease (CAD). Methods We performed a case-control study in patients who had finished the Familial Atherosclerosis Treatment Study (FATS) and returned to usual care with statin therapy alone or had elected to participate in the 20-year FATS-Observational Study (FATS-OS) and received combination therapy with lovastatin (40 mg/day), niacin (2–3 gm/day), and colestipol (20 gm/day) for 11 years, then continued with simvastatin (10–80 mg/day) or lovastatin (40–80 mg/day) plus niacin (2–4 gm/day). After 17.8 ± 0.8 years with combination therapy and 19.0 ± 0.8 years with usual care, cholesterol levels and CIMT were collected in 43 FATS-OS patients and 26 usual care patients. Results Combination therapy group had a greater decrease in total cholesterol (-42 ± 14% vs. ?31 ± 17%, p=0.008) and low density lipoprotein cholesterol (LDL-C) (-57 ± 13% vs. ?38 ± 25%, p<0.001) and greater increase in high density lipoprotein cholesterol (HDL-C) (38 ± 43% vs. 15 ± 23%, p=0.02) as compared to usual care. CIMT (0.902 ± 0.164 vs. 1.056 ± 0.169 mm, p < 0.001) on intensive therapy was significantly less compared to usual care. Multivariate regression analysis (coefficient, 95% CI) showed that combination therapy (-0.13, ?0.21 – ?0.04, p=0.003) and on-therapy LDL-C (0.15, 0.02 – 0.28, p=0.03) were significant independent predictors of CIMT. Conclusions Prolonged combination lipid therapy is associated with greater improvements in LDL-C and HDL-C levels and less atherosclerotic burden as compared to statin therapy alone. PMID:25234561

    Invasive yeast infections cause significant morbidity and mortality. Surveillance for the infection is necessary to detect trends in species distribution and antifungal resistance. We performed this retrospective study of yeast infection at Jinling Hospital, Nanjing in China, from year of 2010 to 2012. A total of 341 yeast isolates were obtained from patients with invasive infections in the period. Among these isolates, Candida spp. comprised of the highest percentage of yeast strains (91.8 %), followed by Cryptococcus neoformans (5.9 %) and other non-Candida yeast strains (2.3 %). Bloodstream isolates made up 41.3 % of yeast strains and the isolates from CVC made up 17.3 %. Among Candida spp., C. albicans was the most common species identified from non-blood clinical specimens (42.9 %), but appeared in only 20.8 % of blood isolates (P < 0.001). C. tropicalis was the most prevalent Candida species in the blood samples (28.5 %). Candida spp. was mainly isolated from specimens of the ICU patients, while C. neoformans was mainly isolated from specimens in medical wards. Resistance to FLC occurred in 3.7 % of C. albicans, 9.9 % of C. tropicalis, 74.0 % of C. glabrata, and 4.4 % of C. parapsilosis. Most (>92 %) isolates of C. albicans, C. tropicalis, C. parapsilosis, and C. neoformans strains were susceptible to VRC; However, 26.7 % of isolates of C. glabrata were VRC resistant. PMID:25588889

    The Community-Based Care for Orphans and Vulnerable Children (CBCO) program operated in Kenya during 2006–2010. In Eastern Province, the program provided support to approximately 3000 orphans and vulnerable children (OVC) living in 1500 households. A primary focus of the program was to support savings and loan associations composed of OVC caregivers (typically elderly women) to improve household and OVC welfare. Cross-sectional data were collected in 2011 from 1500 randomly selected households from 3 populations: program participants (CBCO group, n = 500), households in the same villages as program participants but not in the program (the local-community-group = Group L, n = 300), and households living in nearby villages where the program did not operate (the adjacent-community-group, Group A, n = 700). Primary welfare outcomes evaluated are household food security, as measured by the Household Food Insecurity Access instrument, and OVC educational attainment. We compared outcomes between the CBCO and the subset of Group L not meeting program eligibility criteria (L-N) to investigate disparities within local communities. We compared outcomes between the CBCO group and the subset of Group A meeting eligibility criteria (A-E) to consider program impact. We compared outcomes between households not eligible for the program in the local and adjacent community groups (L-N and A-N) to consider if the adjacent communities are similar to the local communities. In May-June 2011, at the end of the OVC program, the majority of CBCO households continued to be severely food insecure, with rates similar to other households living in nearby communities. Participation rates in primary school are high, reflecting free primary education. Among the 18–22 year olds who were “children” during the program years, relatively few children completed secondary school across all study groups. Although the CBCO program likely provided useful services and benefits to program participants, disparities continued to exist in food security and educational outcomes between program participants and their non-OVC peers in the local community. Outcomes for CBCO households were similar to those observed for OVC households in adjacent communities. PMID:23745629

    Alpine ecosystems are especially vulnerable to climate change, and lakes and ponds act as early indicators. Here, we describe our findings for the Ortles-Cevedale mountain group (Stelvio National Park, Southern Alps, Italy), where we used remote sensing to analyze more than 100 water ponds over the last 50 years (1954-2007). We found that since the 1980s, some lower elevation ponds (< 2500 m a.s.l.) have disappeared or experienced surface area reduction. We link this impact to the increased evaporation/precipitation ratio associated with climatic warming. At higher elevations (> 2900 m a.s.l.), we observed that since the 1950s, ponds have increased in size and that new ponds have appeared as a consequence of glacial shrinkage and retreat. However, these new ponds are ephemeral. The appearance of new environments is usually followed by their rapid disappearance and by a concomitant appearance of new ones, which is a clear sign of a transition from a glacial system to a paraglacial system. Surface area changes have been shown to be a highly visible and easily measurable signal of the impact of climate change on the alpine environment, as already demonstrated in other remote areas of the world. There is a clear need to extend this analysis to other sites in the Alps to gain a regional understanding of the phenomenon. The findings of this study make it possible to interpret the variations created by climate change in these environments, in terms of alteration of their ecological role and the loss of ecosystem services.

  9. Is the rare biosphere real or a technical artifact? A case study involving a multi-year deep subsurface time series

    The question of "who" is present in extreme environments is one of the major questions surrounding geobiological research. Techniques such as high-throughput sequencing and single cell genomics are illuminating previously unseen organisms that exist in low abundance. Commonly referred to as the "rare biosphere", the contribution of these low abundance organisms and the effect that they have on traditional diversity estimates is poorly understood. Here, we present a study that critically examines the effect that sequencing depth has on the Chao1 alpha diversity estimator and the Sørensen similarity index. This is achieved through (1) a theoretical analysis of simulated community distributions and (2) a comparison between subsurface Sanger-sequenced clone libraries and high-throughput amplicon sequences generated from a 1.3 km deep fracture (Be326_Bh2). The screening of single cells, metagenomics, and metatranscriptomics are then used to assess the authenticity and contribution of rare members identified in the deeply sequenced amplicon datasets of Be326_Bh2. In particular, a "rare" (<1% relative abundance in 16S rDNA V6 amplicon libraries) member of Ignavibacteria that has been identified and sequenced through single cell genomics is molecularly tracked over the course of a 3-year sampling campaign in Be326_Bh2 while other "rare" members prove to be merely sequencing artifacts. Ultimately, these results help us better understand the limitations of methods used to calculate diversity in long-tail environments like the terrestrial deep subsurface and the role that the rare biosphere plays in Be326_Bh2.

    Bioplastique is a biphasic polymer for the permanent augmentation of some soft tissues. It was developed in 1987, and clinical studies at this institution were begun in 1990. The combination of low molecular weight polyvinylpyrrolidone and solid polymer particles allows the implantation of permanent polymer spheres through a small needle under local anesthesia. In this study 127 cases are reviewed of consecutive patients who have received Bioplastique for scar revision, wrinkles, and augmentation for soft-tissue defects at 6 years after application. All patients who had not been in for follow-up recently were contacted by mail and questioned on the permanence of augmentation and migration of particles. About 30 percent of the patients were unreachable and had their charts reviewed for permanence and migration of particles. In eight of these cases, Bioplastique was removed because of overcorrection, two of them may have had infection. Bioplastique has gained wide use throughout the world and although some complications have been reported, in general, it functions quite well when used in selected cases. PMID:9385974

    The first successful attempt to instrument an Ocean Drilling Program borehole for formation pressure and temperature monitoring and fluid sampling was accomplished in 1991 in Hole 857D, and the system there has been in nearly continuous operation since that time. This hole and others that followed have provided many new insights into ocean crustal and subduction zone hydrogeology and geodynamics, while at the same time being the "proving ground" for a number of technological advances in ocean borehole monitoring, including 1) the CORK scheme itself for sealing holes for hydrologic recovery to natural-state conditions after drilling; 2) the use of absolute pressure sensors for monitoring both relative formation pressures and changes in seafloor depth; 3) multi-level completions for pressure monitoring that leave cased borehole interiors open for other instrumentation; 4) the development of ultra-high-precision, low-power digital recording systems for examining the effects on the formation of seismic and microseismic loading; and 5) the proof-of-concept of an optical communications system that eliminates dependence on submersibles or ROVs for data download operations (see Tivey et al., this session). Relatively low-sample-rate data spanning the first part of the more than two decades of operations have shown how large anomalous pressures generated thermally and by deformation can be; how seafloor tidal loading influences formation pressure and can drive an "a.c." component of flow; and how seismogenic and slow strain can be observed by way of formation-fluid pressure transients. More recent instrumentation has allowed much higher fidelity observations (1 Hz sampling at a resolution of 10-8 of full-scale), and thus is permitting complementary studies of hydrologic, oceanographic, seismic, and microseismic phenomena. Plans for the future include connections to shore via observatory cable systems, such as those of NEPTUNE Canada and DONET, for unlimited power supply and real-time data acquisition (the first having been connected in 2009), and incorporation of quartz sensors, under development at Paroscientific Inc. and Quartz Seismic Sensors Inc., that are coupled to acceleration for monitoring tilt and ground motion.

    Norotte, G; Apoil, A; Travers, V

    1988-01-01

    Fifty-eight patients (52 males and 6 females) operated on for Dupuytren contracture were examined by the same author with a more than ten year follow-up. At time of surgery the average was 55 years old. 69 hands (169 fingers) rated 4.33 according to the simplified Tubiana's score were treated by the same operative procedure: Mac Indoe's incision, digital Z plasty (if needed), subtotal fasciectomy and physiotherapy beginning 8 days postoperatively. At long term, recurrence appears for 49 hands (71%) one every two in the two first postoperative years, one out of five after five years. 24 of them were graded stage I. The recurrence appeared 14 times associated with an extension of the disease and the earlier, the higher was the initial stage. Some factors seem to be of a bad prognosis regarding recurrence: age (93% of recurrence under 50 years old) Ledderhose or Lapeyronie (100%) other associated diseases (Alcoholism, diabetes mellitus, epilepsy) and severe preoperative stage. Subjective results are good: 45 patients are satisfied and only 3 underwent a second operation. PMID:3233038

    Fireworks are used worldwide to celebrate popular events (e.g. festivals, official celebrations, weddings). The festival of lights (Diwali) is celebrated with fireworks in India. During this period, many patients from all age groups present to hospital with injuries due to fireworks. Prevalence, period of occurrence, sex and age variation, adult supervision, causative fireworks, mode of lighting, age groups prone to injury, patterns of injury caused by individual fireworks, and the body parts injured were studied. One hundred and fifty-seven cases (92 retrospective, 65 prospective) with injury due to fireworks presenting to the Department of Plastic Surgery at KEM Hospital between 1997 and 2006 were studied. The prevalence of injuries has decreased steadily over the last 10 years (41 cases in 1997, 3 cases in 2006). The maximum number of injuries (35%) was seen in the age group 5-14 years; 92% of these children were unsupervised. The commonest cause of injury was firework misuse (41% of cases), followed by device failure (35%). Device failure was commonest with flares/fountains (ground firework emitting sparks upwards) and aerial devices. Flare/fountains caused most injury (39%), sparklers the least (0.6%). Flare/fountains, ground spinners, sparklers, and gunpowder (explosive material from cracker, obtained by tearing paper wrapper and obtaining chemicals) caused only soft tissue burns; stringbombs (high-intensity fire cracker made by wrapping chemicals with jute strings/coir in layers) and rockets (aerial device that zooms upwards and bursts) caused blast injuries, leading to soft tissue disruption and bony injuries. Emergency surgery was done if indicated: tendon and/or neurovascular repair, fracture fixation, flap cover or amputation. Superficial burns were treated with dressings. Certain wounds needed only thorough cleansing of the wound and primary suturing. We concluded that, over a 10-year period, the prevalence of firework injury decreased due to increased awareness in the community. Aggressive awareness campaigns by government and non-government organisations was the cause. We can minimise the number and severity of accidents by raising awareness regarding safety precautions, encouraging professional displays and motivating manufacturers to adhere to strict quality control.

    2011-12-01

    Educators in medical schools around the world are presently experimenting with innovative ways of using web-based learning to supplement the existing teaching and learning process. We have recently used a popular open-source course management system (CMS) called the modular object-oriented dynamic learning environment (Moodle) to construct an online site (DPhysiol) to facilitate our face-to-face teaching of physiology to a group of first-year students in the Bachelor of Medicine and Bachelor of Surgery program. The integration of the Moodle site into our teaching was assessed using online log activity, student examination marks, and feedback from students. The freely available Moodle platform was simple to use, helped to effectively deliver course materials, and has features that allowed cooperative learning. Students who used the CMS throughout their academic year and commented favorably regarding its use as a complement to the face-to-face classroom sessions. The group of students used the CMS obtained significantly higher scores in the final examination compared with the previous class that did not use the CMS. In addition, there was a significant correlation between student participation and performance in online quizzes and their final examination marks. However, students' overall online usage of the CMS did not correlate with their examination marks. We recommend Moodle as a useful tool for physiology educators who are interested in integrating web-based learning into their existing teaching curriculum. PMID:22139773

    Summary Introduction:?Acoustic nerve tumors have been recognized as a clinico-pathologic entity for at least 200 years, and they represent 90% of cerebellopontine angle diseases. Histologically, the tumors are derived from Schwann cells of the myelin sheath, with smaller tumors consisting of elongated palisade cells, while in large tumors, cystic degeneration can be found in the central areas, possibly due to deficient vascularization. We retrospectively reviewed 825 cases of vestibular schwannomas, reported between January 1984 and August 2006, in which the patients underwent surgery to remove the tumor. Objective:?To evaluate signs, symptoms, aspects of clinical diagnosis, including the results of audiological and imaging studies, and surgical techniques and complications. Methods:?A retrospective chart review. The medical records of all patients undergoing surgical treatment for schwannoma during the period indicated were reviewed. Results and Conclusion:?Hearing loss was the first symptom reported in almost all cases, and tumor size was not proportional to the impairment of the auditory threshold. The surgical techniques allowed safe preservation of facial function. In particular, the retrolabyrinthine route proved useful in small tumors, with 50% preservation of hearing. PMID:25991975

    2009-01-01

    Background In 2001, the observed annual mortality from Creutzfeldt-Jakob disease (CJD) in Switzerland increased from less than 1.5 to 2.6 per million inhabitants. An underlying cause could not be identified. Methods To analyse potential risk factors for sCJD in Switzerland, close relatives of 69 sCJD-patients and 224 frequency age-matched controls were interviewed in a case-control study using a standardised questionnaire. 135 potential risk factors including socio-demographics, medical history, occupation and diet were analysed by logistic regression adjusting for age, sex and education. Results sCJD patients were more likely to have travelled abroad, worked at an animal laboratory, undergone invasive dental treatment, orthopaedic surgery, ophthalmologic surgery after 1980, regular GP visits, taken medication regularly, and consumed kidney. No differences between patients and controls were found for residency, family history, and exposure to environmental and other dietary factors. Conclusion Although some factors were significantly more frequent among sCJD-cases, this study did not reveal specific explanations for the increased incidence of deaths due to sporadic CJD observed in Switzerland since 2001. Results have to be interpreted with caution due to multiple testing and possible recall bias in association with a long incubation period. The most plausible reason for the increase in Swiss sCJD cases after 2000 is an improved case ascertainment. Therefore, underreporting of cases might well have occurred before the year 2001, and the "real" yearly incidence of sCJD might not be lower than, but rather above 2 per million inhabitants.

    2015-12-15

    Facing a generalized increase in water degradation, several programmes have been implemented for protecting and enhancing the water quality and associated wildlife, which rely on ecological indicators to assess the degree of deviation from a pristine state. Here, single (species number, Shannon-Wiener H', Pielou J') and multi-metric (Estuarine Fish Assessment Index, EFAI) community-based ecological quality measures were evaluated in a temperate estuary over an 8-year period (2005-2012), and established their relationships with an anthropogenic pressure index (API). Single metric indices were highly variable and neither concordant amongst themselves nor with the EFAI. The EFAI was the only index significantly correlated with the API, indicating that higher ecological quality was associated with lower anthropogenic pressure. Pressure scenarios were related with specific fish community composition, as a result of distinct food web complexity and nursery functioning of the estuary. Results were discussed in the scope of the implementation of water protection programmes. PMID:26586512

    Transition into higher education requires students to adjust to a new environment while showing greater independence in managing their own academic and personal life. This is often more difficult for international students who have to adjust to a different country, culture, and potentially another language. A cohort of first-year veterinary medicine students (17% international students) was investigated at a UK university using qualitative and quantitative questionnaires rating first-year experience and support services and statistical analysis of students' assessment performance. While the overall undergraduate perception was that they had learned a lot and progressed well, students in both groups struggled to cope with the workload. The non-UK educated students and students with English as a foreign language also struggled more with teaching delivery in lectures and participation in self-directed group learning and were more likely to feel that the veterinary degree program was too difficult. There was no statistical difference in how British and international students perceived the support system, although it was noticeable that the level of tutorial support was perceived as tutor-dependent. The international students particularly struggled with the assessments in early modules and also with the spot assessment method. However, in the practical assessments, using observed, structured practical exam stations, international and British students performed equally well. Increased support in the initial transition time, especially with regard to communication skills and confidence required for interactive teaching and learning environments such as small-group teaching, as well as increased time for specific assessment types, might benefit the needs of many international students.

    In the last twenty years we have diagnosed 9 cases of congenital sucrase-isomaltase deficiency. In all the cases the diagnosis was made before 9 months of age and was confirmed by quantitative determination of sucrase-isomaltase activity in jejunal mucosal homogenates. Malnutrition and dehydration were frequent findings. In 3 cases there was clinical intolerance to dextrinomaltose and to glucose polymers. In the 6 cases in which were performed, abnormal breath H2 test after an oral sucrose load was found. Lactase activity was above the mean in all cases and an important decrease of maltase activity was demonstrated. The enzymatic deficiency persisted even though the clinical tolerance to sucrase improved with age. PMID:2368994

    Previous climate model simulations have shown that the configuration of the Earth's orbit during the early to mid-Holocene (approximately 10-5 kyr) can account for the generally warmer-than-present conditions experienced by the high latitudes of the northern hemisphere. New simulations for 6 kyr with two atmospheric/mixed-layer ocean models (Community Climate Model, version 1, CCM1, and Global ENvironmental and Ecological Simulation of Interactive Systems, version 2, GENESIS 2) are presented here and compared with results from two previous simulations with GENESIS 1 that were obtained with and without the albedo feedback due to climate-induced poleward expansion of the boreal forest. The climate model results are summarized in the form of potential vegetation maps obtained with the global BIOME model, which facilitates visual comparisons both among models and with pollen and plant macrofossil data recording shifts of the forest-tundra boundary. A preliminary synthesis shows that the forest limit was shifted 100-200 km north in most sectors. Both CCM1 and GENESIS 2 produced a shift of this magnitude. GENESIS 1 however produced too small a shift, except when the boreal forest albedo feedback was included. The feedback in this case was estimated to have amplified forest expansion by approximately 50%. The forest limit changes also show meridional patterns (greatest expansion in central Siberia and little or none in Alaska and Labrador) which have yet to be reproduced by models. Further progress in understanding of the processes involved in the response of climate and vegetation to orbital forcing will require both the deployment of coupled atmosphere-biosphere-ocean models and the development of more comprehensive observational data sets.

    In China, the gender ratio of suicide rates did not match the Western patterns, which was higher for females than males. However, the rural men were at relatively high risk of suicide in Liaoning province. Impulsivity was an important factor of suicide behaviors, but there was a lack of studies in China. This research aimed to study the relationship between impulsive personality traits and suicidal behavior among Chinese rural youths. Suicides were consecutively sampled from six randomly selected counties in Liaoning Province in China. Between 2005 and 2007, a total of 162 suicide victims were enrolled in the study along with 162 community controls matched for age, gender, and location. The psychological autopsy method was used to collect data from informants knowledgeable about the selected suicide victims and controls. The results showed the suicide victims in the study were more likely to demonstrate dysfunctional impulsivity and less likely to demonstrate functional impulsivity compared with the controls. Mental disorders, acute negative life events, and dysfunctional impulsivity contributed to the risk of suicide; educational and functional impulsivity were protective factors. Suicide prevention efforts in rural China may address impulsivity. PMID:26110614

  12. Releasing the digital elevation model for the whole Italian territory: a case study reporting two years of core-data dissemination for Earth Sciences communities and other stakeholders

    EPOS (European Plate Observing System) is the European initiative for the implementation and integration of European Research Infrastructures in the field of Solid Earth Sciences. In particular, EPOS is aimed at creating a common environment for data exchange for both the scientific community and relevant stakeholders interested in Earth Sciences. In such a context, a service providing access to the complete topography of one of the countries participating in EPOS represents a step forward towards the realization of the EPOS mission. Here we report about two years of activity of a data dissemination service which released (for free) a digital elevation model (DEM) of the whole Italian territory at 10 m-resolution named TINTALY/01. The new TINITALY/01 DEM for the whole Italian territory was completed and presented by INGV in 2007. This DEM was the final result of a project funded by the Italian Ministry of the Environment. TINITALY/01 was completed in two phases: in a first phase, independent elevation models for single regions were derived, and in a second phase, all the regional models were merged into a single, seamless model covering the whole territory of Italy. In early 2012, a web portal was published (http://tinitaly.pi.ingv.it/) through which the above DEM is open for a full web-GIS navigation (3-D navigation in anaglyph mode or standard 2-D hillshade), and where internet navigators can ask for the download of the DEM dataset (in grid format, 10 m-resolution) through the compilation of an online form (http://tinitaly.pi.ingv.it/account_request_form.html). Submission of the form implies stating the destination of use for the data, and acceptance of the policy of use (i.e. no-profit use). After nearly two years from the opening of the portal, the DEM is still browsed by up to 10-20 users per day (about 3000 visits throughout 2013). As of 31 December 2013, about 220 users affiliated to nearly 150 different institutions or associations (i.e. universities, research institutes, local administrations, etc..) based on 20 different countries (10% of the users from outside Europe) have been accredited for the download of the DEM. The analysis of the destinations of use declared by users shows that they have very different interests, ranging from any branch within Earth Sciences (e.g. Gravimetry, Volcanology, Seismics, Geomorphology etc..) to applied Physics, Archaeology and History, Zoology, Forestry Sciences, Remote Sensing, Civil Protection, Land Use Planning and Environmental Management etc. Although this service was originally designed and set up outside the EPOS umbrella, the present report illustrates the utility and need of even relatively small infrastructures for the dissemination of core data in the field of Earth Sciences. This experience shows that a similar service can attract the interest of a large variety of scientific communities and private and public stakeholders, which can largely benefit from the availability of similar core-data. To date, TINITALY/01 is the DEM with the highest resolution freely accessible for the whole Italian territory.

    Changes in relative sea-level (RSL) during the mid- to late Holocene are reconstructed based on internal beach ridge geometry imaged by ground-penetrating radar. Data were collected across a raised beach-ridge system on the island of Samsø, Denmark. The internal architecture of the beach-ridge system is divided into characteristic radar facies. We identify downlap points interpreted to mark the transition from the beachface to the upper shoreface, which we assume to represent actual sea-level at the time of deposition. The absolute vertical level of the identified downlap points are combined with an age-distance model based on optically stimulated luminescence dated samples to construct a RSL curve for the past c. 5000 years. To our knowledge, this is the longest RSL reconstruction based on this proxy. The dataset shows that the period between c. 4800-3800 yr BP was characterized by relatively high RSL values of c. 2.3 m above mean sea level. A marked decrease in RSL of c. 1.3 m occurred between c. 3800-3600 yr BP at a rate of c. 5 mm/yr. After c. 3500 yr BP the RSL curve shows a gradually decrease at a rate of c. 0.6 mm/yr. This new data set further revealed reflections interpreted as beach steps. In combination with estimated changes in dip values of interpreted beachface reflectors, these observations may provide information about changes in the morphodynamic conditions of beach-ridge construction and progradation through time.

    Ecological disturbance and climate are key drivers of temporal dynamics in the demography and genetic diversity of natural populations. Microscale refuges are known to buffer species' persistence against environmental change, but the effects of such refuges on demographic and genetic patterns in response to short-term environmental variation are poorly understood. We quantified demographic and genetic responses of mountain brushtail possums (Trichosurus cunninghami) to rainfall variability (1992-2013) and to a major wildfire. We hypothesized that there would be underlying differences in demographic and genetic processes between an unburnt mesic refuge and a topographically exposed zone that was burnt in 2009. Fire caused a 2-year decrease in survival in the burnt zone, but the population grew after the fire due to immigration, leading to increased expected heterozygosity. We documented a fire-related behavioural shift, where the rate of movement by individuals in the unburnt refuge to the burnt zone decreased after fire. Irrespective of the fire, there were long-term differences in demographic and genetic parameters between the mesic/unburnt refuge and the nonmesic/burnt zone. Survival was high and unaffected by rainfall in the refuge, but lower and rainfall-dependent in the nonmesic zone. Net movement of individuals was directional, from the mesic refuge to the nonmesic zone, suggesting fine-scale source-sink dynamics. There were higher expected heterozygosity (HE ) and temporal genetic stability in the refuge, but lower HE and marked temporal genetic structure in the exposed habitat, consistent with reduced generational overlap caused by elevated mortality and immigration. Thus, fine-scale refuges can mediate the short-term demographic and genetic effects of climate and ecological disturbance. PMID:26089175

    The purpose of this article was to educate nurses about the possibility of patients having an allergic reaction to polymethyl methacrylate (PMMA). Although rare, an allergic reaction to PMMA or the bone cement used to adhere the metal components of a total knee arthroplasty (TKA) to the bone can cause aseptic loosening of a TKA ( S. A. Edwards & J. Gardiner, 2007). The prevalence of PMMA allergies in the population has not been reported in the literature; therefore, no high-level research studies on the subject are available ( K. Kaplan, C. Della Valle, K. Haines, & J. D. Zuckerman, 2002). A case study and literature review was used to construct this article. The patient, L.W., a 61-year-old, white woman, is a nail technician with a history of right knee pain, stiffness, soreness, and a decreased range of motion for one and a half years following a TKA. The complications from a PMMA allergy could be avoided by adding one or two questions to the patient's history and physical form. A complete history could also do away with the need for additional testing and increased medical expenses for the patient and the healthcare system as a whole. PMID:26213878

    Early clinical features of lead toxicity are non-specific and an occupational history is particularly valuable. Lead in the body comprises 2% in the blood (t1/2 35 days) and 95% in bone and dentine (t1/2 20–30 years). Blood lead may remain elevated for years after cessation from long exposure, due to redistribution from bone. Blood lead concentration is the most widely used marker for inorganic lead exposure. Zinc protoporphyrin (ZPP) concentration in blood usefully reflects lead exposure over the prior 3 months. Symptomatic patients with blood lead concentration >2.4 µmol l−1 (50 µg dl−1) or in any event >3.8 µmol l−1 (80 µg dl−1) should receive sodium calciumedetate i.v., followed by succimer by mouth for 19 days. Asymptomatic patients with blood lead concentration >2.4 µmol l−1 (50 µg dl−1) may be treated with succimer alone. Sodium calciumedetate should be given with dimercaprol to treat lead encephalopathy.

    Introduction Jigger infestation is an important but neglected public health problem. The study assessed the knowledge, attitude and practices of household members on jigger infestation, practices and control within Murang'a district, a rural location in Kenya. Methods A cross-sectional descriptive study design was used. Structured interview schedules and observation checklist were used to collect quantitative data. A sample size of 271 household members was interviewed. Descriptive and inferential statistics were analyzed and odds ratios computed at 95% confidence interval to determine variables association. Results On knowledge, 70.1% acknowledged poor hygiene and sanitation contributes to jigger infestation while 16.6% identified jigger flea as the cause of jigger infestation. Over half (53.9%) reported jiggers are transmissible from person to person. Majority (94.8%) identified signs and symptoms of jigger infestation. Over a quarter (23.6%) reported an infested household member and 18.8% infested persons were confirmed during the study. Many (59.8%) held the opinion that, jigger infested persons are lazy, 26.2% reported they are poor and 12% reported they either have specific blood or are from certain families. Below half (48.7%) believed in myths and misconceptions on jiggers. Majority (90.8%) reported needles/pins were the mostly used jigger removal items followed by thorns 38.7%. About two thirds (62.0%) were not aware of communal jigger prevention and control activities. The Chi-square results showed that, the village, type of house floor and compound maintenance were significantly associated with jigger infestation (p<0.05). Conclusion Knowledge on jigger infestation is high but this has not translated to jigger prevention and control in the area. PMID:23467785

    Reliably predicting the future state of the hydrological system under transient climate and land use conditions is a major challenge. Hydrological models are usually calibrated and validated for a short time period (e.g. 30 years), for conditions that are similar to today's. In order to test model performance for future (unverifiable) projections, palaeohydrological modelling is first needed to build confidence in model output under different conditions. One of the major challenges of palaeohydrological modelling is the acquisition of verification data that is representative for the past state(s) of the hydrological system. Here, we present the reconstructed evolution of the groundwater table depth over the last six centuries, in a sandy interfluvium (20 km² with altitude varying between 16 m and 28 m a.s.l.) of the Nete catchment. For periods before 1770 AD, the altitude (depth) of blown-out surfaces in the drift sand landscape is used as a proxy for the average highest groundwater level. These surfaces are generally interpreted as the lower limit for wind erosion. Soil profiles investigations where these surfaces are overblown by younger drift sand show that they were created in the time period between ca. 1400 AD and 1600 AD. For younger periods, historical maps were analysed for the presence of surface water features, such as fens (shallow lakes that are groundwater fed in this sandy landscape under temperate climate), marshes and wetlands. The results clearly show declining water levels in the second half of the 19th century, i.e., between 1854 AD and 1909 AD. The decline is most pronounced for the higher areas of the interfluve (drift sand landscape) and becomes less clear towards the floodplains. The amount of groundwater level decline is 1-2 m on average. The cause for the synchronous groundwater level drop seems to be linked to land use and land cover changes during that period. In the time interval between 1854 AD and 1909 AD, the total length of drains increased from 2 km to 25 km, while land cover changed from 80% heathland and almost no trees to only 20% heathland and 50% coniferous forest. Available palaeoclimate records suggest that there is no correlation between groundwater level change and average annual temperature or precipitation. Furthermore, population density seems to be uncorrelated with the observed hydrological changes. Internal consistency checks are performed and found satisfactory. For example, the high groundwater levels predicted by the blown-out surfaces for 1400-1600 AD are confirmed by surface water features on younger historical maps (~1770 AD and ~1850 AD). Indeed, pollen analysis, topographical maps and climate records show that land cover and climate did not change significantly throughout the period 1400 AD to 1850 AD. We conclude that the proposed methods are useful tools to gather verification data (i.e., groundwater table depth) for palaeohydrological modelling in the European sand belt during the last millenium.

    The aim of this study was to determine the intensity variation of the earth magnetic field by using Miocene and Quaternary basaltic rocks in Eastern Anatolian region. A total of ninety one volcanic rocks at twelve different sites are sampled around the Van region. A modified Thellier method was used to determine paleointensity values. Paleointensity results from five sites were accepted according to our confidence criteria. The paleointensity values from the five reliable sites with normal polarity show relatively low paleointensity values compared to the present field of 47 µT. The total paleointensity field values F are 33.96± 3.54 µT for site VAN5 with an age of 5.5 m.y, 19.98± 6.79 µT for site VAN7 with an age of 4.3 m.y, 26.07 ±8.41 µT for site VAN8 with an age of 0.1 m.y, 29.98 ±1.71 µT for site VAN11 with an age of 0.4 m.y and 31.08 ±2.88 µT for site VAN12 with an age of 5.5 m.y. The average VDMs (Virtual Dipol Moments) correspond to 6.01x10²² Am² for the three Miocene sites and to 5.73x10²² Am² for the Quaternary rocks. Our data is in good coherence to previous studies of similar age ranges.

    This article illustrates some issues we faced during our experience in conducting an epidemiologic case–control study of inflammatory breast cancer in North Africa. We expect that some of the questions we had to ask in order to address these issues might be helpful to others in setting up epidemiologic studies in developing regions. We describe our experience from different angles including the use of multiple sites to achieve adequate sample size, standardizing diagnosis of disease, identifying cancer cases at the time of diagnosis, control selection procedures, logistics of study implementation, questionnaire development and interviewing, biologic specimens, and procedures for protection of human subjects. We have developed a brief checklist to summarize important issues for conducting future epidemiologic studies in these or similar low- or middle-income countries. PMID:23342283

    Atypical and unusual locations of psoriasis are very frequent. However, localized linear psoriasis is rare, with few cases described in the literature. It is characterized by a linear distribution of psoriasis lesions along Blaschko lines. We report the case of a three years old child, who presented unilateral erythematous scaly plaques arranged along Blaschko lines in the left hemithorax, with no associated symptoms and no lesions in other parts of the body. The differentiation of linear psoriasis from other linear dermatoses is not easy. The combination of a thorough history, a careful examination of the skin and histopathology are essential to ensure the correct diagnosis and appropriate treatment. PMID:26312714

  11. Health-related quality of life in adolescents with screening-detected celiac disease, before and one year after diagnosis and initiation of gluten-free diet, a prospective nested case-referent study

    PubMed Central

    2013-01-01

    Background Celiac disease (CD) is a chronic disorder in genetically predisposed individuals in which a small intestinal immune-mediated enteropathy is precipitated by dietary gluten. It can be difficult to diagnose because signs and symptoms may be absent, subtle, or not recognized as CD related and therefore not prompt testing within routine clinical practice. Thus, most people with CD are undiagnosed and a public health intervention, which involves screening the general population, is an option to find those with unrecognized CD. However, how these screening-detected individuals experience the diagnosis and treatment (gluten-free diet) is not fully understood. The aim of this study is to investigate the health-related quality of life (HRQoL) of adolescents with screening-detected CD before and one year after diagnosis and treatment. Methods A prospective nested case-referent study was done involving Swedish adolescents who had participated in a CD screening study when they were in the sixth grade and about 12 years old. Screening-detected adolescents (n = 103) and referents without CD who participated in the same screening (n = 483) answered questionnaires at the time of the screening and approximately one year after the screening-detected adolescents had received their diagnosis that included the EQ-5D instrument used to measure health status and report HRQoL. Results The HRQoL for the adolescents with screening-detected CD is similar to the referents, both before and one year after diagnosis and initiation of the gluten-free diet, except in the dimension of pain at follow-up. In the pain dimension at follow-up, fewer cases reported problems than referents (12.6% and 21.9% respectively, Adjusted OR 0.50, 95% CI 0.27-0.94). However, a sex stratified analysis revealed that the significant difference was for boys at follow-up, where fewer screening-detected boys reported problems (4.3%) compared to referent boys (18.8%) (Adjusted OR 0.17, 95% CI 0.04-0.73). Conclusions The findings of this study suggest that adolescents with unrecognized CD experience similar HRQoL as their peers without CD, both before and one year after diagnosis and initiation of gluten-free diet, except for boys in the dimension of pain at follow-up.

    This paper describes the clinical course of a pediatric patient developing cervical external root resorption (CERR). An 11-year old male patient had sustained dental trauma and was diagnosed with crown fracture affecting the incisal and middle thirds of the maxillary right permanent central incisor and the maxillary right permanent lateral incisor with pulp exposure and CERR after 24 months. Diagnosis and treatment of CERR are a challenge for dental practitioners. In this case, preservation of natural dentition is shown as a successful treatment in a 6-year follow-up. PMID:25870717

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    A retrospective study was undertaken of all cases of death in adults (>16 years) due to electrocution which were autopsied at Forensic Science SA, Adelaide, Australia, over a 30-year period from 1973 to 2002. A total of 96 cases were identified with 87 males (91%) (mean age=41.6 years; range 17 to 86 years) and nine females (9%) (mean age=49.2 years; range 20 to 76 years). Deaths were due to accidents in 66 cases (69%; M:F = 63:3), suicides in 28 cases (29%; M:F=24:4) and homicides in two cases (2%). Both homicide victims were females, with females accounting for only 5% of the accidents and 14% of suicides. The number of accidental deaths increased until the early 1990s and then declined, whereas suicidal electrocutions were only found in the last 20 years of the study. Most deaths (N = 80; 83%) were due to low voltage circuits (<1000 volts), with deaths due to high voltages occurring in 15 cases (16%). One death was due to lightning (1%). While suicides were evenly distributed throughout the year, most accidental deaths occurred in late spring and summer (N = 42; 64%) with the lowest number of accidental deaths occurring in winter and early spring. This report demonstrates a significantly higher rate of electrocution deaths among males, with a summer predominance of accidental deaths, most likely due to increased outdoor activities in better weather. The reduction in cases over the last decade of the study may be a reflection of the success of workplace and domestic safety campaigns. Female electrocution suicides and electrocution homicides were rare events. PMID:16683472

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    Objectives In Denmark, the local and regional health authorities share responsibility for cardiac rehabilitation (CR). The objective was to assess effectiveness of CR across sectors coordinated by a nurse case manager (NCM). Design A one-year follow-up study. Setting A CR programme (GoHeart) was evaluated in a cohort at Lillebaelt Hospital Vejle, DK from 2010 to 2011. Participants Consecutive patients admitted to CR were included. The inclusion criteria were the event of acute myocardial infarction or stable angina and invasive revascularization (left ventricular ejection fraction (LVEF) ?45%). Main outcome measures Cardiac risk factors, stratified self-care and self-reported psychosocial factors (SF12 and Hospital Anxiety and Depression Scale (HADS)) were assessed at admission (phase IIa), at three months at discharge (phase IIb) and at one-year follow-up (phase III). Intention-to-treat and predefined subgroup analysis on sex was performed. Results Of 241 patients, 183 (75.9%) were included (mean age 63.8 years). At discharge improvements were found in total-cholesterol (p?year follow-up these outcomes were maintained; additionally there was improvement in body mass index (BMI; p?year follow-up.

    BACKGROUND AND OBJECTIVES: Because breast cancer in men is rare, few patients are available for prospective studies. To learn more about its epidemiology, risk factors, clinical features, genetics and pathology in our country, we conducted a retrospective study of all cases seen in recent decades at our institution. PATIENTS AND METHODS: We identified each case of male breast cancer in the database at the Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir, India, between the years 1983 to 2007. RESULTS: We identified only 32 cases of male breast cancer over the 24-year period. Male breast cancer accounted for 32 (2.8%) of 1141 resected breast specimens, which included all breast lesions and 32 (4.1%) of 780 breast cancer cases. Of the 32 cases, 20 (62.5%) had various associated risk factors. Invasive ductal carcinoma was seen in 30 cases (93.7%). Of 20 cases that underwent molecular studies, 16 (80%) patients had estrogen receptor positivity whereas 14 (70%) had progesterone receptor positivity. Six cases (30%) overexpressed HER2 and p53. The BRCA2 mutation was observed in 4 cases (40%) while no patient presented with the BRCA1 mutation. CONCLUSION: An incidence of 4.1% for male breast cancer indicates that this disease is not as uncommon as presumed in this part of the world. Breast cancer in men seems more frequently to be hormone receptor positive and the BRCA2 mutation confers a significant risk to men. PMID:19584580

    Purpose To study appropriateness of our modified screening criteria for detection of all cases of Retinopathy of Prematurity (ROP) among preterm babies. Method Retrospective observational cohort study among preterm neonates who underwent ROP screening as per set protocol for 11 years at Nizwa Hospital, Al Dhakilya Governorate, Oman. We screened all babies with gestational age ⩽32 weeks or BW ⩽ 1500 g. Preterm babies >32 weeks of GA or BW > 1500 g with unstable clinical course believed to be at high risk by the attending neonatologist also were screened. Results During the study period 528 babies were screened for ROP of which 76 babies were excluded due to death, associated congenital ocular malformation and loss for follow-up either due to transfer to other institution or defaulting. Thus 452 babies were included in the final analysis. Incidence of ROP was 46.4% of which 27.9% had mild ROP, 11.3% had severe ROP which regressed and 7.3% had severe ROP who were treated. The incidence of ROP among infants with GA < 26 wks, 26–28 wks, 29–30 wks, 31–32 wks and above 32 weeks was 100.0%, 80.0%, 59.3%, 34.4% and 19.4% respectively. 56 babies of this cohort belonged to Extended (modified) criteria group. Among these 12 babies had ROP out of which 9 had mild ROP and 3 had severe ROP. Among cases with severe ROP, two cases regressed spontaneously and one case needed treatment. Multivariate analysis using stepwise regression model showed statistically significant association of GA and BW to development of ROP. We would have missed few babies with ROP if we had followed other criteria. Conclusion Our modified screening criteria seem to be appropriate as no infant with severe ROP was missed during the study period. Incidence of severe ROP among babies in the extended criteria group (5.4%) is low but significant compared to lower gestational age. We plan to formulate a scoring system following all risk factor analysis to enable us to optimize the number of infants screened. Detection of all babies with ROP is important as they need long-term follow-up for the timely detection and management of associated ocular comorbidities. PMID:26949350

    A 35-year-old man was observed during a 21-year period with fundus color photography, fluorescein angiography, and B-scan ultrasonography for a presumed retinoma detected in his left eye during routine ophthalmoscopy in 1982. The patient was a carrier of the 13q14 retinoblastoma gene. His retinal lesion remained stable during the follow-up period without signs of malignant transformation. Retinomas are most commonly observed in patients with retinoblastoma and their relatives. In this case, none of the patient's parents, siblings, or children had evidence of a retinal tumor. Photographic documentation of the nonprogressive nature of this presumed retinoma is provided and demonstrates the absence of growth. PMID:15792319

    Criminal death incidence of women varies between developed and developing countries, and it has become a common public problem in almost every country. We do not have any data about femicide cases published in Turkey until today. In our study, we tried to call attention to femicide cases. In our study, we evaluated 141 cases of female homicides with an interval of 10 years between January 1996 and May 2005, retrospectively. Data retrieved were statistically evaluated using chi-square test. Most of the cases were between 21 and 35 years of age. Spouse murders are usually witnessed during the process of divorce. Establishment of institutions which will ensure the security of women during this period is of paramount importance. If we protect women during divorce and separation proceedings, we can prevent femicide cases. We also think that laws may be strengthened for protecting women who are vulnerable at such times.

    Deglutition syncope has been demonstrated in isolated case reports, the first being described over 50 years ago. It is thought to be caused by a hypersensitive vagotonic reflex in response to esophageal dilation after swallowing. It can cause syncope due to complete atrioventricular (AV) block and acute reduction of cardiac output. Although rare, its lethality is worthy of discussion, as early recognition can offer complete treatment with placement of a pacemaker. A 54-year-old man presented with 30 years of lightheadedness and syncope, followed by disorientation and tremors, after eating sandwiches or drinking carbonated beverages. He initially was evaluated by a neurologist. Work-up included cardiac 2D transthoracic echocardiogram, electroencephalogram, swallow stud, pulmonary function tests, electrocardiogram, and cardiac stress testing. All tests were within normal limits, and it was determined that he was suffering from convulsive syncope and deglutition syncope. Referral to the cardiac electrophysiology department with tilt-table testing accompanied by swallow evaluation was then recommended. The tests demonstrated marked vagal response resulting in sinus bradycardia with second-degree AV block and pauses up to 3.5 seconds. Patient experienced near syncope. A rate-responsive, dual-chamber Boston Scientific pacemaker with DDDR programming was implanted. Patient has remained asymptomatic at follow-up. PMID:23882389

    1999-12-01

    Review was undertaken from February 1969 to January 1998 at the State forensic science center (Forensic Science) in Adelaide, South Australia, of all cases of murder-suicide involving children <16 years of age. A total of 13 separate cases were identified involving 30 victims, all of whom were related to the perpetrators. There were 7 male and 6 female perpetrators (age range, 23-41 years; average, 31 years) consisting of 6 mothers, 6 father/husbands, and 1 uncle/son-in-law. The 30 victims consisted of 11 daughters, 11 sons, 1 niece, 1 mother-in-law, and 6 wives of the assailants. The 23 children were aged from 10 months to 15 years (average, 6.0 years). The 6 mothers murdered 9 children and no spouses, with 3 child survivors. The 6 fathers murdered 13 children and 6 wives, with 1 child survivor. This study has demonstrated a higher percentage of female perpetrators than other studies of murder-suicide. The methods of homicide and suicide used were generally less violent among the female perpetrators compared with male perpetrators. Fathers killed not only their children but also their wives, whereas mothers murdered only their children. These results suggest differences between murder-suicides that involve children and adult-only cases, and between cases in which the mother rather than the father is the perpetrator. PMID:10624923

  2. The case for a fourth international polar year

    Bindschadler, R.

    2003-04-01

    Our polar exploring ancestors created a unique legacy for those who continue to unravel the mysteries of these fascinating regions. Within the polar research communities, justification for enduring the rigors of polar work to solve these mysteries is usually not necessary. However, to the public at large and the policy makers around the world, constant reminders of the global relevance and universal importance of polar processes are required. International Polar Years at quarter and half-century intervals have provided opportunities to reemphasize these critical points, push back the edge of the unknown with exciting polar discoveries and sow the seeds of future understanding through the collection of new data sets. The next opportunity for such a reemphasis is the year 2007. Polar research has gained enormous credence in global climate research since the International Geophysical Year (initially planned as the Third International Polar Year) in 1957. Exploring these links with new studies and a much expanded autonomous measurement network to monitor key parameters are obvious candidates for a Fourth International Polar Year. At the same time, there are vast, yet unexplored areas of Antarctica, particularly the subglacial environment where geology, glaciology and biology combine to form unknown tectonic and biotic conditions. New technologies are required to conduct some of the exploratory research and to make feasible remote measurements in the often-harsh polar environment. These technological developments also afford the use of polar regions as a test bed for future planetary missions to icy worlds such as Mars and Europa.

    In our previous study of 3-year-old children in a dioxin contamination hot spot in Vietnam, the high total dioxin toxic equivalent (TEQ-PCDDs/Fs)-exposed group during the perinatal period displayed lower Bayley III neurodevelopmental scores, whereas the high 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-exposed group displayed increased autistic traits. In autistic children, urinary amino acid profiles have revealed metabolic alterations in the amino acids that serve as neurotransmitters in the developing brain. Therefore, our present study aimed to investigate the use of alterations in urinary amino acid excretion as biomarkers of dioxin exposure-induced neurodevelopmental deficits in highly exposed 3-year-old children in Vietnam. A nested case-control study of urinary analyses was performed for 26 children who were selected from 111 3-year-old children whose perinatal dioxin exposure levels and neurodevelopmental status were examined in follow-up surveys conducted in a dioxin contaminated hot spot. We compared urinary amino acid levels between the following 4 groups: (1) a high TEQ-PCDDs/Fs and high TCDD-exposed group; (2) a high TEQ-PCDDs/Fs but low TCDD-exposed group; (3) a low TEQ-PCDDs/Fs exposed and poorly developed group; and (4) a low TEQ-PCDDs/Fs exposed and well-developed group. Urinary levels of histidine and tryptophan were significantly decreased in the high TEQ-PCDDs/Fs and high TCDD group, as well as in the high TEQ-PCDDs/Fs but low TCDD group, compared with the low TEQ-PCDDs/Fs and well-developed group. However, the ratio of histidine to glycine was significantly lower only in the high TEQ-PCDDs/Fs and high TCDD group. Furthermore, urinary histidine levels and the ratio of histidine to glycine were significantly correlated with neurodevelopmental scores, particularly for language and fine motor skills. These results indicate that urinary histidine is specifically associated with dioxin exposure-induced neurodevelopmental deficits, suggesting that urinary histidine may be a useful marker of dioxin-induced neurodevelopmental deficits and that histaminergic neurotransmission may be an important pathological contributor to dioxin-mediated neurotoxicity.

    Two Belgian caves yielded very rich large mammal associations dating around 30 to 40,000 years ago: Goyet and Scladina cave (layer 1A). These sites are only 5 km apart but the cave entrances open on different valleys, in a quite diverse landscape ranging between open, unprotected uplands, steep cliffs and sheltered sun-exposed gorges, with the larger Meuse valley nearby. This mosaic scenery permitted during the Last Glacial a rich diversity of fossil flora and fauna. The faunal association includes a large diversity of taxa including Aurochs Bos primigenius, steppe bison Bison priscus, reindeer Rangifer tarandus, giant deer Megaloceros giganteus, horse Equus ferus, woolly rhinoceros Coelodonta antiquitatis, woolly mammoth Mammuthus primigenius, cave bear Ursus spelaeus, brown bear Ursus arctos, wolf Canis lupus, cave lion Panthera leo spelaea, and cave hyaena Crocuta crocuta spelaea. All the 90 studied bones and teeth yielded collagen with excellent collagen preservation, allowing reliable investigations of carbon, nitrogen and sulfur isotopic biogeochemistry. The combination of three different isotopic tracers allows to deciphering the effects of food selection and landscape use by different herbivorous and carnivorous taxa. This is the first study to include sulfur isotopic signatures in the study of late Quaternary large mammal palaeobiology. This new tracer yields evidence on mobility and differences in pasture areas, as different geological bedrock may exhibit various sulfur isotopic signatures that will pass on the herbivores and further on their predators. Using this feature in addition to the trophic information provided by carbon and nitrogen isotopic signatures, it appears that for some species present in both sites, such as horse and woolly rhinoceros, the individuals found in each site probably did not use the same pasture areas. This seems to also the case for the overwhelmingly vegetarian cave bears. In addition, individuals from the same species found in one site sometimes exhibit clear isotopic differences in the three isotopic tracers that suggest different pasture grounds as well, and therefore the possibility of different herds in the vicinity of the cave site. In the case of cave hyeanas, the isotopic signatures of individuals from both caves are not significantly different and suggest that these predators obtained their prey from a large territory including the pasture grounds of herbivores from both caves. In addition, direct radiocarbon dating of some of the studied collagen allows to investigating possible chronological trends. This study shows how new isotopic tracers can provide invaluable information on late Quaternary large mammal palaeobiology.

    Objective: To show the experience of the Erasto Gaertner Hospital with hemipelvectomy surgery over a 10-year period. Methods: This was a retrospective study on 32 patients who underwent hemipelvectomy at Erasto Gaertner Hospital between 1998 and 2008, assessing clinical and surgical characteristics. Results: Among the 32 patients, 15 were female and 17 were male. The mean age was 37.94 years. Eight cases showed involvement of the neurovascular bundle: three were located in the iliac and extended to the thigh, two were in the acetabulum and extended to the thigh and three were in the acetabulum and pubis. Twenty-three cases presented a neurovascular bundle free from neoplasia: 11 were restricted to the iliac, six were in the acetabular region, two were in the pubic ramus and four extended to the whole hemipelvis bone. One case involved the iliac-femoral vessels: one in the pubic ramus. Seven cases of chondrosarcoma and four cases of Ewing's sarcoma represented the majority. Eight cases underwent external hemipelvectomy and 24 underwent internal hemipelvectomy (11 were type I; four were type II; two were type II + III; three were type III and four were type IV). Of these 24 cases, 13 did not have any reconstruction, 10 had a fibular graft and one had an iliacfemoral vein and artery prosthesis. Twenty-six surgeries were curative and six were palliative. There were 14 deaths. Survival of two and five years was seen in 11 and 10 cases, respectively. For six cases, less than two years had passed since the operation. Three cases were lost during follow-up. Conclusion: This study shows the experiences of an oncology reference service specializing in highly complex surgical treatment.

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    Background Intracranial subdural empyema (ISDE) is a pyogenic infection located in the space between the dura and arachnoid mater. Early diagnosis, prompt initiation of antimicrobial therapy, and surgical drainage are essential to reduce morbidity and mortality. This case series analyzes the presentation and management of ISDE in Queensland, Australia, over a 10-year period. Methods Thirty-six patients with ISDE were treated at Gold Coast University Hospital, Princess Alexandra Hospital, Townsville Hospital, and Royal Brisbane Hospital. The patients' medical records were analyzed to ascertain patient demographics, etiology, presentation, and management. Results A slight male preponderance occurred in the cohort of 36 patients with ISDE. The most common source of infection was a neurosurgical procedure, followed by sinusitis and otogenic sources. Headache, fever, and altered sensorium were the most common clinical triad of symptoms, present in 19 (53%) patients. Craniotomy was performed as the initial surgical procedure in 28 (88%) of the 32 patients who required surgery. Seizure prophylaxis was given to 25 (69%) patients, with 8 (32%) of those patients having seizures during their hospitalizations despite this therapy. Five (14%) patients required readmission and a second craniotomy because of failed resolution of the ISDE. Conclusion Altered sensorium, fever, vomiting, and headache should alert the clinician to the possibility of ISDE. A history of neurosurgery, sinusitis, otitis media, or skull trauma increases the likelihood of this differential. Management includes sensitive antibiotic therapy and surgical drainage. Compared with burr hole, craniotomy is associated with less recurrence of ISDE. PMID:24940128

    Bergen, A; While, A

    2000-04-01

    The case study has become an accepted vehicle for conducting research in a variety of disciplines. However, the meaning behind the term is not always made explicit by researchers and this has given rise to a number of assumptions which are open to challenge, and to questions about the robustness of the method. This paper explores some of the issues arising from one particular definition of case study research, used in a study by Yin which examined the practice of case management in community nursing. Four main areas are discussed. First, defining 'case' is seen to pose questions about the relationship of the phenomenon to its context, the degree of researcher control over case definition, the limits to what may constitute a 'case' and what is meant by the term 'unit of analysis'. Second, the relevance of external validity to case study research is supported through the use of a number of tactics, in particular Yin's concept of replication logic, which involves generalizing to theory, rather than to empirical data. Third, the use of method triangulation (multiple methods of data collection) is advanced as a means of enhancing construct validity in research where data converge around a particular theory. Finally, the relationship of the case study to theory construction, through the prior development of 'propositions' is discussed. Each of these issues is applied to the design and conduct of a research study based closely on Yin's multiple case study framework. Thirteen 'cases' were selected of case management practice and data were collected through interviews and examination of literature and documentation, to explore the suitability of community nurses for the role. It is concluded that, given the appropriate subject matter, context and research aims, the case study method may be seen as a credible option in nursing research. PMID:10759989

    In facing the challenges that confront Catholic health care today, it is important to know which civil law forms will assist in preserving the Church's ministry. The proper meshing of civil law and canon law thus provides a vehicle to strengthen the apostolate's work. The case studies presented here suggest several means of applying the principles in the new Code of Canon Law to three potentially problematic situations: the merger of a Catholic and non-Catholic hospital, the leasing of a Catholic hospital to an operating company, and the use of the multicorporate format.

  20. Autoerotic deaths: a 25-year retrospective epidemiological study.

    PubMed

    Sauvageau, Anny

    2012-06-01

    It is written in almost all articles on autoerotic deaths that these fatalities account for about 500 to 1000 deaths per year in the United States and Canada. However, contrary to the general belief, this incidence rate was not obtained through a study, but it is an estimation based on 30-year unpublished data from Canada and England. In the present retrospective study from 1985 to 2009, 38 cases of autoerotic deaths were identified in the province of Alberta (Canada). This number corresponds to an incidence of 0.56 autoerotic deaths per million inhabitants per year. The vast majority of these deaths are related to typical, predominantly asphyxial methods, such as hanging. The bodies were most commonly found in basements, bedrooms, and bathrooms. There is no clear evidence of a preferential time of day for these deaths, but there appear to be slightly more autoerotic deaths during summer. The incidence of autoerotic deaths is higher in big cities compared with rural areas. The previously published estimate of 500 to 1000 'autoerotic deaths per year should not be used for Canada. An incidence of 0.2 to 0.5 cases per million inhabitants per year is a better estimate of the incidence of autoerotic deaths. The incidence in United States should be reassessed using epidemiological studies. PMID:21455055

    Fluoxetine (PROZAC) is a recently marketed straight chain antidepressant unrelated to the cyclic anti-depressants. There is only limited information on fluoxetine and a single case report on overdose (benign outcome) in the literature. In response to this we performed a 1y retrospective chart review at 2 AAPCC certified poison centers. Forty-four exposures to fluoxetine were reviewed from 1988; 31 cases were treated in a HCF, 2 cases were followed at home by phone and 11 cases were lost to follow up. Thirteen cases with follow up (FU) reported no coingestants; 3 cases reported increased anxiety without cardiovascular (CV) changes, 2 cases presented confused with out CV changes, and 8 cases were asymptomatic. Eight cases with FU had ETOH and/or benzodiazepines as a coingestant and experienced only a decreased level of consciousness that could be explained by the coingestant. Five cases remained asymptomatic with reported coingestants of APAP #3, lorazepam, haloperidol, molindone, alprazolam, propranolol, phenobarbital (level 18.2). Four cases were excluded from the evaluation due to the coingestants involved. No seizures were recorded in this series. Three possible drug reactions occurred; 2 cases had reactions with tranylcypromine (PARNATE), and 1 case with a diagnosis of septicemia had a severe hyperthermic reaction with therapeutic coingestants of mephytoin, verapamil, digoxin and indocin. We believe overdose with fluoxetine present minimal risk of serious cardiovascular or neurological complications. PMID:2327065

    Background. This study is intended to determine the causes of pediatric traumatic brain injuries (PTBI) in children aged 14 years or less, and to identify various types of craniocerebral damage resulting from different mechanisms of injury.Methods. From July 1, 1993 to June 30, 2001, a survey on PTBI was conducted in Taiwan. The data of patients used in this study were collected from 56 major hospitals among the age group of 0-14 years. The items in the traumatic brain injury survey included sex, age, causes of injuries, severity, and the eventual outcome.Results. A total of 5349 cases were identified. The male-to-female ratio was 1.69: 1. The incidence rate was higher in the age groups of 4-9 years and 10-14 years. The main cause of PTBI was traffic injury, which accounted for 2537 of the cases (47.3%), followed by falls, 2160 (40.3%). Of all traffic injuries, motorcycle-related injury had the highest incidence, followed by the pedestrian and bicycle-related injury. This study also showed that 83.2% of the patients had mild injury, 9.8% had moderate injury, and 7.0%, severe injury.Conclusions. The results of this study suggest that it is important to decrease all the risk factors in the environment of homes and public areas as much as possible. Helmet wearing and the development of public transportation are essential for the prevention of head injury. PMID:14732368

    Kumar, K; Khilnany, M

    1994-05-01

    Seven computer-assisted interactive videodisc instruction units, based on laboratory cases in the General Pathology course for first-year medical students, were developed. Images from the laser videodisc Slice of Life, contributed previously by one of the authors, and the program "Hypercard stack 2.1" were used to develop these units to provide students with interactive software for independent supplemental review of the laboratory cases studied in the course. With the dual-screen system developed, specific picture frames from the videodisc are retrieved on one screen while the other screen displays the corresponding text. The seven units include two units each on cell injury, inflammation, and neoplasia, and one on opportunistic infections. Each unit contains several case studies, each of which consists of the following: a clinical profile, gross pictures and description of the tissue removed, sequential photomicrographs at successively higher magnifications from various fields of tissue slides and their descriptions, comparison with normal histology of the organ involved, interpretation of the observations and comments, final diagnosis, and a quiz. The histopathologic features are specifically emphasized with programmed, computer-generated pointers to indicate specific cells or structures on the images. Each case also contains a glossary to define terms not familiar to first-year students. Although no comparative performance data are available, evaluation of the units obtained from nine terms of use in the last 5 years indicates that these units are extremely valuable supplemental tools for students for independent review of the laboratory cases.

  6. Rumination Syndrome in Ethiopia: A Case Study

    PubMed Central

    2014-01-01

    Eating disorders are commonly believed to be rare or nonexistent in Africa. However, due to exposure to Western culture, a rise in eating disorders among African women is reported in the literature. This case study describes a 17-year-old Ethiopian girl who meets the DSM-IV-TR and DSM-5 diagnostic criteria for bulimia nervosa and the Rome III Diagnostic Criteria for Functional Gastrointestinal Disorders criteria for rumination syndrome. The article discusses the diagnostic delays, the difficulties in terms of therapy, and the context determinants that—combined with individual psychopathological features—are thought to contribute to the disorders. Health professionals should be informed about the prevalence of eating disorders in Africa and, more specifically, of rumination syndrome in young women with normal intelligence. In light of this case study, it seems necessary to raise awareness with regard to the insufficient evidence on effective therapies for rumination syndrome in individuals without intellectual impairment.

    2010-01-01

    BACKGROUND: Primary cutaneous melanoma still constitutes the main cause of skin cancer death in developed countries, and its incidence in recent years has been increasing in a steady, worrisome manner. OBJECTIVES: This study evaluated the clinical, epidemiological and demographic aspects of this disease, and correlated them with patient prognosis. METHODS: Using epidemiologic and clinical data, we analyzed 84 patients with mild to severe primary cutaneous melanoma treated between 1990 and 2007. Slides containing surgical specimens were analyzed, and new slides were made from archived paraffin sections when necessary. RESULTS: The melanoma incidence was higher in areas of sun exposure, with lesions commonly observed in the trunk for males, and lower limbs for females. In addition to Breslow’s thickness and ulceration (p = 0.043 and p < 0.001, respectively), the mitotic rate per mm2 also correlated with worse patient outcome (p = 0.0007). The sum of ulceration (0 when absent or 1 when present), the Breslow index (1 when <1 mm, 2 when >1 mm and <4 mm, 3 when >4 mm) and the mitotic index (0 when absent or 1 when ?1 per mm2) allowed the establishment of a prognostic score: if the sum was equal to or over three, nearly all (91.7%) patients had systemic disease. The 5-year survival was approximately seventy percent. CONCLUSION: Because American Join Committee of Cancer Staging will update the classification of malignant tumors (TNM) staging in the near future, and introduce mitosis as a prognostic factor, our results show the importance of such a feature. Additional studies are necessary to confirm the importance of a prognostic score as proposed herein. PMID:20360915

    2010-01-01

    After 27 years with no detected cases, an outbreak of anthrax occurred in a beef cattle herd in the south of Sweden. The outbreak was unusual as it occurred in winter, in animals not exposed to meat-and-bone meal, in a non-endemic country. The affected herd consisted of 90 animals, including calves and young stock. The animals were kept in a barn on deep straw bedding and fed only roughage. Seven animals died during 10 days, with no typical previous clinical signs except fever. The carcasses were reportedly normal in appearance, particularly as regards rigor mortis, bleeding and coagulation of the blood. Subsequently, three more animals died and anthrax was suspected at necropsy and confirmed by culture and PCR on blood samples. The isolated strain was susceptible to tetracycline, ciprofloxacin and ampicillin. Subtyping by MLVA showed the strain to cluster with isolates in the A lineage of Bacillus anthracis. Environmental samples from the holding were all negative except for two soil samples taken from a spot where infected carcasses had been kept until they were picked up for transport. The most likely source of the infection was concluded to be contaminated roughage, although this could not be substantiated by laboratory analysis. The suspected feed was mixed with soil and dust and originated from fields where flooding occurred the previous year, followed by a dry summer with a very low water level in the river allowing for the harvesting on soil usually not exposed. In the early 1900s, animal carcasses are said to have been dumped in this river during anthrax outbreaks and it is most likely that some anthrax spores could remain in the area. The case indicates that untypical cases in non-endemic areas may be missed to a larger extent than previously thought. Field tests allowing a preliminary risk assessment of animal carcasses would be helpful for increased sensitivity of detection and prevention of further exposure to the causative agent.

    OAK-B135 Transmission System Improvements for Wind Energy Development in the Upper Midwest and Great Plains: Opportunities and Obstacles. This case study set out to ascertain the validity of three assumptions from the perspectives of stakeholders involved in wind energy and transmission issues in the Upper Midwest and Great Plains. The assumptions, and the stakeholders' reactions to each, are summarized below: Assumption 1--Transmission system improvements would provide significant benefits to the electricity network and its customers. Respondents acknowledge the potential for overall system benefits in the form of reduced line losses, improved grid stability and reliability, and enhanced ability to conduct spot market transactions. They also agree that these benefits relate to specific regional needs. However, there is disagreement over the extent of other benefits such as efficiency gains and cost savings from reduced line losses. Further, environmental and community interest groups point out that none of these benefits are realized without significant financial, environmental and social costs. Assumption 2--The benefits of transmission improvements would be helpful, but not confined, to wind power. All respondents agree that wind energy could benefit from transmission system improvements. But they also acknowledge, reluctantly, in the case of environmental stakeholders, that the benefits of an improved transmission system cannot be limited to environmentally preferable forms of generation. Some environmental and community advocate respondents also feel that transmission system improvement projects can be avoided altogether through energy conservation and efficiency measures, and by substituting wind energy for fossil generation. Assumption 3--Transmission alliances among stakeholders within and external to the wind community can provide benefits in the public interest. The fractured, multi-jurisdictional governance of the regional transmission system, and the distrust and diversity of perspectives among affected stakeholders, may make the formation of multi-stakeholder alliances necessary to accomplishing transmission goals. If the wind industry and utilities want to partner with environmental and community advocate groups in supporting a transmission project, they may have to convince these groups that the project would result in a net environmental benefit. The project proponents would have to make the case that the benefits of the additional wind energy will at least offset the emissions of any additional fossil generation made possible by the transmission project, as well as offset the environmental impact of the transmission project itself.

    Aim To examine the changes in the number of children younger than 18 who were hospitalized due to alcohol intoxication at the Department of Pediatrics, University Hospital of Split, from November 1, 1997 to October 31, 2007. Methods Data on children hospitalized due to intoxication were retrieved from hospital medical records. Children were classified into 4 age groups: 0-5, 6-9, 10-13, and 14-18 years, and their sex and type of intoxication were recorded. For children with alcohol intoxication, data on time of intoxication, reason for drinking, presence of injuries or suspected suicide attempts, and possible presence of other drugs in the organism were collected. Results Out of 29?506 hospitalized children, 594 were hospitalized due to intoxications. Out of these, 239 (40.2%) were hospitalized due to intoxication by alcohol. More boys than girls were hospitalized (71.1%). The proportion of alcohol intoxication cases among all types of intoxication cases increased from 16.7% in 1997/98 to 66.3% in 2006/07. The proportion of patients hospitalized due to alcohol intoxication increased from 0.3% of all hospitalized children in the first year to 1.7% in the last year of the study (P?=?0.015, z test for comparison of two proportions). Eighty two per cent of cases of alcohol intoxication were in the 14-18 age-group. The number of alcohol intoxication cases increased among girls from 1 case (6.3% of all intoxication cases among girls) in 1997/98 to 15 cases (45.5%) in 2006/07, while among boys it increased from 6 cases (23.1% of all intoxicated boys) in 1997/98 to 44 cases (78.6%) in 2006/07. Children usually drank outside their homes (79.4%) and mostly on weekends and holidays (73.2%). Conclusion The alarming increase in the number of hospitalizations due to alcohol intoxication in children, especially among girls and in the adolescent age group, represents a serious problem, which requires further attention and research.

    Traditionally, site assessments for delineating petroleum hydrocarbon releases have been conducted in several phases. One way to improve the traditional assessment and remedial investigation methodology is to utilize alternative sampling techniques such as drive point sampling, combined with on-site field analytical methods. There are several drive point sampling technologies which have been used successfully in the past several years to collect both soil and groundwater samples. These drive point techniques include the Geoprobe{trademark}, Hydropunch{trademark}, Cone Penetrometer Testing (CPT) and KV{trademark} Sampling System. Utilized in combination with an on-site mobile laboratory equipped to conduct headspace analysis by EPA method 3810, these drive point sampling methods provide immediate, real-time data at a lower cost per data point. This paper presents three case studies in utilizing the Geoprobe{trademark} as an alternative sampling technology to gather both soil and groundwater data to delineate site contamination and provide for more informed, remedial solutions. In two of the cases (retail service stations), remediation by groundwater pump and treat had been on-going for several years with little remedial progress. The use of the alternative sampling technologies provided the needed information to expedite site clean-up. The remaining site is a petroleum refining facility where an active recovery system was planned. In this case, the data provided through the expedited assessment provided imperative design information.

    BACKGROUND: Lichen planus is considered to be the most common dermatological disease involving the oral mucosa. OBJECTIVE: To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus. METHODS: A total of 21 patients were selected from 258 patients at risk for oral cancer development. RESULTS: Most of the patients were white (76,2%), female (66,6%), with mean age of 58.8 years. Eight were smokers and seven were alcohol consumers. The buccal mucosa was the most affected site, followed by the tongue and the gingiva. The reticular pattern was the most common appearance. Histopathology depicted dysplasia in nine cases and cytopathology was positive for Candida in eight cases in the first appointment. CONCLUSION: Our data are similar to the literature. Cytopathology was important for the diagnosis of candidiasis. Although the presence of dysplasia was verified, further studies are necessary to clarify the importance of this finding. PMID:26131860

    This is a case study of a lactating grandmother. Thini Bai, married for 34-36 years and living in the village of Pantaniya, had been through menopause 3-4 years prior to her condition. A grandson named Bantu, whose mother had died of malaria two days after his birth, was left under her care. She related that she had let Bantu suckle at her breast to pacify him. After a while she noticed changes in her breast size and fullness, in the color spread of the areolae, and in nipple consistency. Eventually, milk was being secreted. She continued to breast-feed 8-10 times a day as she had done when she was a mother. An increase in weight of 75 g in the child was subsequently noted. At the time of investigation, Bantu's age was 6 months and his weight was 6.5 kg. This is a unique case of a postmenopausal grandmother lactating after a minimum of 16 years since last lactation.

    The quantitative real time polymerase chain reaction (qPCR) has become a key molecular enabling technology with an immense range of research, clinical, forensic as well as diagnostic applications. Its relatively moderate instrumentation and reagent requirements have led to its adoption by numerous laboratories, including those located in the Arabian world, where qPCR, which targets DNA, and reverse transcription qPCR (RT-qPCR), which targets RNA, are widely used for region-specific biotechnology, agricultural and human genetic studies. However, it has become increasingly apparent that there are significant problems with both the quality of qPCR-based data as well as the transparency of reporting. This realisation led to the publication of the Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines in 2009 and their more widespread adoption in the last couple of years. An analysis of the performance of biomedical research in the Arabian world between 2001–2005 suggests that the Arabian world is producing fewer biomedical publications of lower quality than other Middle Eastern countries. Hence we have analysed specifically the quality of RT-qPCR-based peer-reviewed papers published since 2009 from Arabian researchers using a bespoke iOS/Android app developed by one of the authors. Our results show that compliance with 15 essential MIQE criteria was low (median of 40%, range 0–93%) and few details on RNA quality controls (22% compliance), assays design (12%), RT strategies (32%), amplification efficiencies (30%) and the normalisation process (3%). These data indicate that one of the reasons for the poor performance of Arabian world biomedical research may be the low standard of any supporting qPCR experiments and identify which aspects of qPCR experiments require significant improvements.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    2015-01-01

    Herein we discuss a rare variant of hangman’s fracture in an eighty year old male with good Karnofsky performance score. We performed X-ray and magnetic resonance imaging (MRI) of the cervical spine to confirm the diagnosis. The patient was placed on a gentle cervical traction which showed good reduction. Despite being on a resource limited setup,  we performed posterior occipitocervical fusion with bone graft fusion followed by early mobilization. A postoperative scan showed good reduction and purchase of the screws. This case highlights the importance of choosing the correct therapeutic attitude for the management of the geriatric population especially in those who do not have any significant co-morbid conditions.

    1993-01-01

    A 5-year prospective study on the time course of women's gymnastics injuries was conducted on a successful NCAA Division I team. Gymnasts recorded injuries on a computer terminal or via computer dot sheets immediately before each training session, including the injured body part, the event or activity, and the date of the injury. The definition of injury was "any damaged body part that would interfere with training." Athletes recorded injuries on the 1st day of onset and subsequently until the injury was healed. The initial onset of injury was considered a new injury. Subsequent records of the injury were considered continuing injury. Thirty-seven athletes participated through five collegiate seasons. They accounted for 5602 total training exposures with an average of 151.4 exposures per athlete. The analyses showed that gymnasts trained with an injury approximately 71% of the exposures, and a new injury could be expected from a gymnast during approximately 9% of the exposures. The largest number of injuries were of the repetitive stress syndrome type. The time series information showed that total injuries tended to increase until the middle of the competitive season, while new injuries showed prominent increases during specific training periods and during competition preparation and performance.

    Benign osteoblastoma refers to a benign tumor of the bone. Osteoblastoma most commonly affects the vertebrae and long tubular bones, however, in rare cases is observed in the facial bones. The current study presents the case of a 12-year-old female patient with a tumor in the mandibular body. Radiological imaging revealed a lesion with regular contours. The lesion was radically resected and histological analysis of the specimen demonstrated features that are typical of a benign osteoblastoma. The consequential defects of the jaw were reconstructed using titanium implants and autologous bone transplantation. The patient remains disease free subsequent to a five-month follow-up period. The aim of the present report is to present a rare case of benign osteoblastoma of the mandible. This study demonstrated that correct diagnosis and complete surgical excision are important to reduce the risk of recurrence of a benign osteoblastoma. PMID:25364451

    This work aimed to prospectively record all primary central nervous system tumor (PCNST) cases in France, for which histological diagnosis is available. The objectives were to (i) create a national registry and a network to perform epidemiological studies; (ii) implement clinical and basic research protocols; and (iii) harmonize the health care of patients affected by PCNST. For 5 years, 25?756 cases of newly diagnosed and histologically confirmed PCNST have been recorded. Histological diagnoses included glioma (48.9%), all other neuroepithelial tumors (5%), meningioma (28.8%), nerve sheath tumors (8.4%), lymphoma (3.2%) and others (5.7%). Cryopreservation was reported for 6018 PCNST specimens. Tumor resections (R) were performed in 78% cases, while biopsies accounted for 22%. Median age (MA), sex, percentage R and number of cryopreserved tumors were detailed for each histology; for example, out of 6053 glioblastomas (MA 63 years, male 59.4%, R 62%, 1611 were cryopreserved), and out of 37 atypical teratoid/rhabdoid tumors (MA 2 years, male 56.8%, R 94%, 17 were cryopreserved). This database or databank dedicated to PCNST cases contains detailed data on clinical, histological and other characteristics, such as the inclusion of data on cryopreserved specimens that are not available in other European registries. Therefore, this is a valuable resource that can be used for planning future epidemiological and clinical research. PMID:21554472

    1996-03-01

    Congress has given NASA and the science community a reality check. The tight and ever shrinking budgets are trimming the fat from many space science programs. No longer can a Principal Investigator (PI) afford to waste development dollars on re-inventing spacecraft controllers, experiment/payload controllers, ground control systems, or test sets. Inheritance of the Ground Support Equipment (GSE) from one program to another is not a significant re-use of technology to develop a science mission in these times. Reduction of operational staff and highly autonomous experiments are needed to reduce the sustaining cost of a mission. The re-use of an infrastructure from one program to another is needed to truly attain the cost and time savings required. Interface and Control Systems, Inc. (ICS) has a long history of re-usable software. Navy, Air Force, and NASA programs have benefited from the re-use of a common control system from program to program. Several standardization efforts in the AIAA have adopted the Spacecraft Command Language (SCL) architecture as a point solution to satisfy requirements for re-use and autonomy. The Environmental Research Institute of Michigan (ERIM) has been a long-standing customer of ICS and are working on their 4th generation system using SCL. Much of the hardware and software infrastructure has been re-used from mission to mission with little cost for re-hosting a new experiment. The same software infrastructure has successfully been used on Clementine, and an end-to-end system is being deployed for the Far Ultraviolet Spectroscopic Explorer (FUSE) for Johns Hopkins University. A case study of the ERIM programs, Clementine and FUSE will be detailed in this paper.

    2015-01-01

    The effectiveness of local destructive treatments (LDT) applied in patients due to cervical pathology oncogenic risk (OR), were followed and verified in 396 patients who came to our attention, focusing on the type of pathology, type of treatment received, diagnosis clinical evolutionary, and results of the new study applying polymerase chain reaction (PCR), and above all, the time between the diagnosis, treatment, and PCR findings. The clinical evolution of the same reports achieved a healing rate of 82% followed by persistence 8.3%; improvement 4.8%, recurrence 2.8%, and only one case of progression 0.2%. The elapsed time in initial care and treatment was almost immediate, as the pathology diagnosis was considered on an emergency basis. Successive controls of these indicated that 119 studies of routine colposcopy were carried out, on an average of the first three years and with a maximum follow up of 30 years, with over 30 routine colposcopies that achieved healing in most of these. In 2011 and 2012, we added to the usual diagnostic methodology, molecular biology, and 119 studies were performed in those patients, resulting in only five negative cases. Most studies were classified as high risk papillomavirus (HR-HPV), corresponding to subtypes 31, 35, 18, and 16. PMID:26189261

    A 1999 white paper predicted a revolution in lighting technology by extrapolating the 30-year history of red LEDs to estimate the performance and cost for white LED lamps for the following two decades. In this Expert Opinion, Haitz and Tsao discuss the hits and misses of the 1999 predictions and analyze the necessary and sufficient conditions for this revolution to succeed. The graph on the cover updates the flux and cost performance for red and white LEDs and confirms that these 1999 predictions still hold. The global wave of investments in R&D and manufacturing infrastructure triggered by the 1999 graph will continue, thus leaving little doubt that this disruptive technology will dominate the lighting industry, not this year or the next, but over the next two decades.

    Retained cardiac pellets are clinically silent foreign bodies that do not cause any cardiovascular disturbance. A 71-year-old woman presented with exertional chest pain. Her physical examination and surface electrocardiogram were normal. After a positive treadmill test, coronary angiography was performed which showed nonsignificant coronary lesions. During fluoroscopy, several pellets were observed throughout the neck and two of them were simultaneously moving within the heart shadow. Transthoracic and transesophageal echocardiography showed no evidence for pericardial effusion. Computed tomography scans of the chest showed the pellets above the left diaphragm in the pericardial area. Her past medical history revealed an accidental shot from a pellet rifle by her son 25 years before, at which time no surgical intervention was planned as she had been asymptomatic. PMID:21200124

    The precise prevalence of molluscum contagiosum (MC) is still unknown. The pediatric studies showed a cumulative incidence of 17% in children less than 15 years, but there are no studies available for Romania. The papular skin lesions are generally less than 5 mm, but the immunocompromised patients may develop large uncommon lesions. The pediatric cases are located mostly on the limbs, trunk or the face. The lab investigations are not usually required because the clinical features are typical. A biopsy followed by a light microscopy may help in some cases. We are presenting the case of a 6-year-old boy suffering from MC since almost a year. When examined in our clinic, the child developed 2 to 4 mm dome-shaped flesh-colored papules with central umbilication on his trunk diagnosed as MC. The microscopic examination revealed bud-like proliferation of the epidermis, molluscum bodies and moderate chronic inflammation of the dermis. In about one month of treatment, all the lesions disappeared without other local or general complications. PMID:26429183

    The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burn injuries retrospectively. An analysis of autopsy records revealed 19.4% cases of burn injuries amongst the total autopsies done over 10years period (1993-2002) in the mortuary of the department of Forensic Medicine of Kasturba medical College, Manipal. The majority of deaths (78.5%) occurred between 11 and 40years of age group with preponderance of females (74.8%). The flame burns were seen in 94.1% of the victims followed by scalds and electrical burns in 2.8% and 2.5% cases, respectively. The majority of burn incidents were accidental (75.8%) in nature followed by suicidal (11.5%) and homicidal (3.1%) deaths. The percentage of burn (TBSA) over 40% were observed in most of the cases (92.5%). The majority of deaths occurred within a week (69.87%) and most the victims died because of septicemia (50.9%).

    Objective The prevalence of stone diseases is high in Turkey. Thanks to the technological improvements and to the increase in the number of qualified and experienced specialists in the last thirty years, there has been an increase in the application of minimally invasive methods in the stone disease surgery. This study, with a sample survey of Western Black Sea region, aims at revealing the changes and improvements in the treatment of stone diseases in different centers in Anatolia within the last ten years. Material and methods Six centers in 4 of the provinces of the Western Black Sea Region were selected and the patients’ files were retrospectively analyzed. The treatment methods that were recommended for and/or applied to the patients diagnosed with urinary stone diseases were recorded by years. The urinary stone diseases were divided into three separate groups; kidney, ureters and bladder. Treatment options were recorded into categories as open surgery, percutaneous nephrolithotripsy, retrograde intrarenal surgery, semirigid ureterorenoscopy, flexible ureterorenoscopy, and ESWL. Results A total of 26044 patients with stone diseases have been treated in the above-mentioned centers for the last 10 years. The distributions of the stone diseases in relation to their localization were as follows: - kidney stones: 9040 (34.7%), ureter stones: 15264 (58.6%), and bladder stones: 1740 (6.7%). As for the distribution of the treatment in relation to the treatment methods, it was seen that open surgery for 1032 (4%) patients, endoscopic surgery for 15038 (58%) patients, and ESWL for 9974 (38%) patients had been applied. While URS and PCNL are currently the commonly used treatment methods in the Western Black Sea Region, RIRS has begun to be used in a limited number of patients for the last 3 years. Conclusion Though being a little late, the advances in endrourology offer practical applications in the Western Black Sea region as well. Although this study suggests implications for the evaluating of the periphery outcomes of the improvements in stone disease treatments, for the planning of training schemes, and for equipment planning, further research based on more data from more centers is needed to have a nation-wide perspective.

    Objectives Published data indicate that Alpha thalassemia trait is prevalent in 45% of population of Sultanate of Oman. Recent unpublished data suggest that this prevalence is higher than 45%. Yet clinical suspicion or investigations into ?-thalassemias are lacking. Moreover, Hemoglobin H disease is considered rare in Oman. We decided, therefore to look for Hemoglobin H disease and characterize the clinico–hematopathological features of the disease. Methods Patient demographics, clinical details and detailed hematology parametry of Hemoglobin H disease cases, diagnosed by Department of Laboratory over a period of 5 years between February 2002 and January 2007 in patients presenting at Al-Nahdha Hospital and Genetic counseling unit in Muscat were compiled from hospital and laboratory records and analyzed. Results Twenty cases of Hemoglobin H disease in Omanis were diagnosed mainly during the second decade. 60% belonged to Al-Balushi tribe. 40% of cases presented with body pains. 35% presented with nonspecific symptoms. 50% of cases were erroneously labeled as Iron deficiency anemia. Microcytic erythrocytosis, high Red Cell Distribution Width, numerous misshapen Red Blood Cells, pseudothrombocytosis, low A2 and normal Ferritin were important diagnostic clues. Hemoglobin H inclusions in special reticulocyte smears and Hemoglobin H on HPLC or Electrophoresis were diagnostic. Conclusion Hemoglobin H disease is common in Oman. The need to do HPLC, G6PD activity and Ferritin studies in all cases of anemia in Oman to avoid missing diagnosis of Hemoglobin H disease is stressed. This study is intended to create awareness about Hemoglobin H disease in order to diagnose early, treat rightly, counsel correctly and pave the path for prevention of ?-thalassemia disease in Oman.

    This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years; 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered. PMID:25000372

    2009-04-01

    Evidences tell us freak waves are difficult to deal with from a scientific point of view. Though it is generally accepted that in deep water the mechanism involved in the generation is modulation instability there are some doubts about the way such giant waves can appear on a relatively calm sea. Partly the problem could be, it has been pointed out, that the so called evolution equations, as for instance Schrödinger nonlinear equation and further enhancements of this equation are valid for little wave steepness, that we know is not the case with freak waves. On the other hand, statistical description gives us another tool to cop with the problem, not without some shortcomings also. However, as the matter of fact, freak or extreme waves are present in our seas causing accidents, casualties and damages. For that reason the main aim of this research is to collect data from past records in order to see how near or how far we are of the expected conditions to formation of freak waves, once we know some accident has taken place .The purposely practical approach is going to be carried out on a specific case where the above conditions presented themselves, using wave records both, previous and simultaneous, to the location from a nearby station( a deployed buoy). For that end, we are going to use some parameters, as BFI, steepness, shape of the wave, asymmetry, etc., combining, to a certain extent, the deterministic and statistical line of thought.

    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.

    PubMed

    Tay, P

    1996-08-01

    Noise Induced Deafness (NID) is the leading occupational disease in Singapore. Every year, over 500 new cases of NID are detected by the Department of Industrial Health (DIH). Severe NID is a disabling disease which is compensable under the law. A retrospective study was conducted to elicit the profile of workers with severe, disabling NID. From 1 January 1985 to 31 December 1994, the DIH confirmed 127 of such cases. Of these, 57 (44.9%) were involved in the building and repair of ships and boats, 30 (23.6%) with the basic steel industries, manufacture and fabrication of metal products and storage batteries, 9 (7.2%) with the transport and allied support industries, 7 (5.5%) in granite quarrying, 7 (5.5%) in the manufacture of food and drinks, 5 (3.9%) in the manufacture of wooden furniture and 7 (5.5%) in other industries such as manufacture of glass, electricity generation, construction, textiles, printing and so on. The mean age of these workers upon diagnosis of severe NID was 48 years (SD 8.07). The mean duration of exposure to noise was 24 years (SD 9.11). The mean of the average hearing thresholds at 1, 2 and 3 kHz for these workers was found to be 61.5 dBA (SD 4.26). The main jobs at risk were grit blasters, steel workers, fitters, boiler fabricators, panel beaters and carpenters. Noise dosimetry was performed on 46 of the cases and the mean time-weighted exposure level was 90 dBA (SD 10.00). Finally, 82.7% of cases already had audiometric evidence of severe deafness at the time of notification. PMID:8993132

    2013-01-01

    OBJECTIVE: To review the cases of patients with congenital lobar emphysema (CLE) submitted to surgical treatment at two university hospitals over a 30-year period. METHODS: We reviewed the medical records of children with CLE undergoing surgical treatment between 1979 and 2009 at the Botucatu School of Medicine Hospital das Clínicas or the Mogi das Cruzes University Hospital. We analyzed data regarding symptoms, physical examination, radiographic findings, diagnosis, surgical treatment, and postoperative follow-up. RESULTS: During the period studied, 20 children with CLE underwent surgery. The mean age at the time of surgery was 6.9 months (range, 9 days to 4 years). All of the cases presented with symptoms at birth or during the first months of life. In all cases, chest X-rays were useful in defining the diagnosis. In cases of moderate respiratory distress, chest CT facilitated the diagnosis. One patient with severe respiratory distress was misdiagnosed with hypertensive pneumothorax and underwent chest tube drainage. Only patients with moderate respiratory distress were submitted to bronchoscopy, which revealed no tracheobronchial abnormalities. The surgical approach was lateral muscle-sparing thoracotomy. The left upper and middle lobes were the most often affected, followed by the right upper lobe. Lobectomy was performed in 18 cases, whereas bilobectomy was performed in 2 (together with bronchogenic cyst resection in 1 of those). No postoperative complications were observed. Postoperative follow-up time was at least 24 months (mean, 60 months), and no late complications were observed. CONCLUSIONS: Although CLE is an uncommon, still neglected disease of uncertain etiology, the radiological diagnosis is easily made and surgical treatment is effective. PMID:24068262

    This was descriptive study carried out in a medium-sized Brazilian city. In ? 15-year-old contacts of index cases of active pulmonary tuberculosis, we assessed compliance with the Brazilian national guidelines for tuberculosis control. We interviewed 43 contacts and their legal guardians. Approximately 80% of the contacts were not assessed by the municipal public health care system, and only 21% underwent tuberculin skin testing. The results obtained with the Chi-square Automatic Interaction Detector method suggest that health care teams have a biased attitude toward assessing such contacts and underscore the need for training health professionals regarding tuberculosis control programs.

The bases for this claim include a theoretical and an "empirical evaluation" argument. We examined both of these arguments and found them to be incorrect. We describe an appropriate empirical evaluation method to explore the performance of nested case-control study designs and analysis methods from an existing cohort. This empirical evaluation approach relies on simulating case-control outcomes from risk sets in the cohort from which the case-control study is to be performed. Because it is based on the underlying cohort structure, the empirical evaluation can provide an assessment that is tailored to the specific characteristics of the study under consideration. The methods are illustrated using samples from the Colorado Plateau uranium miners cohort. PMID:19289963

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

  13. Giant breast hamartoma in a 41-year-old female: A case report and literature review

    Breast hamartoma is an uncommonly reported benign breast lesion of uncertain cause and pathogenesis. The diagnosis of breast hamartoma by a single method such as mammography, magnetic resonance imaging or sonography is inadequate. In the majority of cases, the breast hamartoma is excised a few years after it has occurred when it is not too big. In the present report, however, a particularly large lesion with a long history is described. Such a case has rarely been reported and shows the necessity of early surgery to reduce trauma as much as possible. Excision of hamartoma was successfully performed and an 11×9×3.5-cm tumor was completely excised. The present study also reviews the literature on breast hamartoma.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals. PMID:26483725

    1991-01-01

    A two year prospective study identified 1922 cases of meningitis in children under 1 year of age. A further 201 cases were identified from other sources. The annual incidence of meningitis during the first year of life was 1.6/1000; during the first 28 days of life it was 0.32/1000, and among postneonatal infants it was 1.22/1000. The male:female ratio was 1.4:1. The overall case fatality rate was 19.8% for neonates and 5.4% for postneonatal infants. Two thirds of deaths identified in the study, 50% of all deaths, were not attributed to meningitis by the Office of Population Censuses and Surveys. Group B beta haemolytic streptococci (28%), Escherichia coli (18%), and Listeria monocytogenes (5%) were most frequently isolated from neonates and Neisseria meningitidis (31%), Haemophilus influenzae (30%), and Streptococcus pneumoniae (10%) from postneonatal infants. At 2-6 months of age N meningitidis meningitis was most common, and at 7-12 months H influenzae predominated. Meningitis caused by group B beta haemolytic streptococci occurred up to 6 months of age and had a consistent mortality of 25%. Neonatal meningitis due to Gram negative enteric rods had a mortality of 32%. Low birth weight was a significant predisposing factor for both neonates and postneonatal infants. In both groups mortality was significantly higher among children admitted in coma. There was no seasonal variation in incidence in either group. Neonates were treated with either group. Neonates were treated with either chloramphenicol (50%) or gentamicin (48%) usually in combination with a penicillin; 40% received a third generation cephalosporin. Of the 1472 postneonatal infants treated 84% received chloramphenicol with a penicillin and 10% received a third generation cephalosporin. Relapse occurred in 49 patients and three died. Eighteen babies coned as a result of raised intracranial pressure, including four neonates, and four died. Mortality among the 133 (7%) children who received steroids was significantly higher than in the rest of the study group. PMID:2039250

    Outage management issues identified from a field study conducted at a two-unit commercial pressurized water reactor (PWR), when one unit was in a refueling outage and the other unit was at full power operation, are the focus of this paper. The study was conduced as part of the US Nuclear Regulatory Commission`s (NRC) organizational factors research program, and therefore the issues to be addressed are from an organizational perspective. Topics discussed refer to areas identified by the NRC as critical for safety during shutdown operations, including outage planning and control, personnel stress, and improvements in training and procedures. Specifically, issues in communication, management attention, involvement and oversight, administrative processes, organizational culture, and human resources relevant to each of the areas are highlighted by example from field data collection. Insights regarding future guidance in these areas are presented based upon additional data collection subsequent to the original study.

    This study evaluated telemark injuries in a Swedish ski area in terms of injury ratio, location, and causes over time. During the seasons of 1989-2000 all injured telemark skiers ( n=94) who attended the medical center in Tärnaby, Sweden, within 48 h after the accident were registered and asked to fill in an injury form. A control group of noninjured telemark skiers were interviewed in the season of 1999-2000. The most common cause of injury was fall (70%) and the injury ratio was 1.2. There was a higher proportion of beginners in the injured population, and they had a fall/run ratio of 0.7, compared with 0.3 for average and advanced skiers. Ankle/foot injuries were most common (28% of injuries) followed by knee (20%) and head/neck (17%). The ankle/foot injuries decreased from 35% to 22% in the seasons 1989-1995 to 1995-2000. Beginners had more ankle/foot injuries than skilled participants. The severity of ankle/foot injuries classified as the Abbreviated Injury Scale group 2 or higher decreased from 33% to 21% during the study period. Twenty-seven percent used plastic and 73% leather boots. We found no association between boot material and ankle/foot injuries. The proportion of high boots with two or more buckles was 51%. High boots appeared to be protective against ankle/foot injuries. The proportion of high boots increased from 24% to 67% during the study period. Thus ankle/foot injuries were the most common injury location, but have decreased over time. The severity of these injuries has also decreased. A possible explanation could be the increased use of high boots. PMID:11734878

    EPA sampled four placer mines in Alaska during the summer of 1998. This was the second phase of a study of the distribution of metals in surface water at placer mines in surface water upstream of the mine site, downstream of the mine discharge, and in the effluent. The second phase examines temporal variations from eight rounds of measurements collected during 1998 from four placer mines located in three mining districts. During the second phase in 1998, EPA obtained field measurements of temperature, pH, electrical conductivity, dissolved oxygen, turbidity, and settleable solids. In addition, EPA analyzed samples for total suspended solids, total recoverable metals, dissolved metals, and hardness. The metals analyses included aluminium, antimony, arsenic, cadmium, calcium, chromium, copper, lead, magnesium, mercury, nickel, selenium, silver, and zinc. The 1998 data show typically large variations in total recoverable and dissolved metals concentrations through the course of the mining season. Consistent with 1997 results, turbidity was an effective indicator for some, but not all, total recoverable metals found in surface waters. In addition to turbidity, total suspended solids measurements showed similar variations with total recoverable metal content.

    The spatial and temporal dynamics of melt ponds and sea ice albedo contain information on the current state and the trend of the climate of the Arctic region. This publication presents a study on melt pond fraction (MPF) and sea ice albedo spatial and temporal dynamics obtained with the Melt Pond Detection (MPD) retrieval scheme for the Medium Resolution Imaging Spectrometer (MERIS) satellite data. This study compares sea ice albedo and MPF to surface air temperature reanalysis data, compares MPF retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS), and examines albedo and MPF trends. Weekly averages of MPF for 2007 and 2011 showed different MPF dynamics while summer sea ice minimum was similar for both years. The gridded MPF and albedo products compare well to independent reanalysis temperature data and show melt onset when the temperature gets above zero; however MPD shows an offset at low MPFs of about 10 % most probably due to unscreened high clouds. Weekly averaged trends show pronounced dynamics of both, MPF and albedo: a negative MPF trend in the East Siberian Sea and a positive MPF trend around the Queen Elizabeth Islands. The negative MPF trend appears due to a change of the absolute MPF value in its peak, whereas the positive MPF trend is created by the earlier melt onset, with the peak MPF values unchanged. The MPF dynamics in the East Siberian Sea could indicate a temporal change of ice type prevailing in the region, as opposed to the Queen Elizabeth Islands, where MPF dynamics react to an earlier seasonal onset of melt.

  2. A longitudinal study of grapheme-color synesthesia in childhood: 6/7 years to 10/11 years

    Grapheme-color synesthesia is a condition characterized by enduring and consistent associations between letter/digits and colors. This study is the continuation of longitudinal research begun by Simner et al. (2009) which aimed to explore the development of this condition in real time within a childhood population. In that earlier study we randomly sampled over 600 children and tested them aged 6/7 and 7/8 years. We identified the child synesthetes within that cohort and measured their development over 1 year, in comparison to a group of non-synesthetic children with both average and superior memories. We were able to show the beginnings of a developmental progression in which synesthetic associations (e.g., A = red) mature over time from relatively chaotic pairings into a system of fixed consistent associations. In the current study we return to this same population three years later when participants are now 10/11 years. We used the same paired-association memory task to determine the synesthetic status of our participants and to also establish synesthetes' inventories of grapheme-color associations. We compared their inventories to those from age 6/7 and 7/8 years to examine how synesthesia matures over time. Together with earlier findings, our study shows that grapheme-color synesthesia emerges with a protracted trajectory, with 34% of letters/digits fixed at age 6/7 years, 48% fixed at 7/8 years and 71% fixed at 10/11 years. We also show several cases where synesthesia is not developing in the same time-frame as peers, either because it has died out at an older age, or because it was slower to develop than other cases. Our study paints the first picture of the emergence of synesthesia in real-time over four years within a randomly sampled population of child synesthetes. PMID:24312035

    Carcinoma cuniculatum of the penis is an extremely rare variant of squamous cell carcinoma characterized by an endophytic deeply branching and burrowing growth pattern. One documented case series demonstrated afflicted patients ranging in age from 73–83 years with the tumour located on the glans penis, coronal sulcus or foreskin. We report a case of a 55-year-old with disease located on the ventral aspect of the shaft of the penis. The tumour was invasive into the deep dermal connective tissue, comparatively superficial to all previous documented cases. He subsequently underwent a partial penectomy. The case is discussed with a brief review of the literature. PMID:20944791

    Endometrial adenocarcinoma (EC) usually occurs after menopause, whereas in 2-14% of cases, it occurs in young patients (less than 40 years old) who may desire to keep their fertility. It is of importance to evaluate women for EC when they develop polycystic ovarian syndrome and abnormal uterine bleeding. Its treatment includes hysterectomy, bilateral salpingo-oo- phorectomy and pelvic lymphadenectomy and in some cases, radiation therapy. We report a case of EC in a 31-year-old woman who presented to Royan Institute. She complained about oligomenorrhea with a 10-year history of primary infertility. PMID:26246886

    Background: Tuberculous meningitis (TBM) is a severe form of extra pulmonary tuberculosis with high mortality and morbidity rate in all age group patients specific in adults and children. The incidence and prevalence are not exactly known in Iran. In this study, we tried to evaluate the role of rapid diagnosis and to find out the highest risk group patients. Methods: Totally, 1783-suspected patients with tuberculous meningitis whose CSF specimens were admitted at Noor Pathobiology Laboratory, Tehran, Iran were enrolled in this study from January 2009 until December 2013. All specimens were checked for MTB by direct examination, culture and PCR tests, and for the adenosine deaminase (ADA). Results: Confirmed positive cases were aged from 13 to 82 yr old with mean age 46.63 yr (SD±18.84). The number of diagnosed positive MTB was different by the 3 applied protocol, 64 by PCR, 28 by culture and 33 by direct examination. Considering the result of PCR protocol the TBM was approved in 64 patients with rate of 3.59%. Two patients had other infection as well, one 56 years old with VZV and the other patient who was HIV positive was 27 years old. Increased ADA titer higher than cutoff was relevant with other results of positive samples except in two cases. Conclusion: Analysis of the results proved adults are more at risk for tuberculous meningitis than children in Iran are. It is also confirmed PCR method provide the most efficient, rapid and reliable results for these patients who are at the critical situations. PMID:26351499

    Birch, Emilie; Andersson, Mikael; Koch, Anders; Stenz, Flemming; Søborg, Bolette

    2014-01-01

    Background The incidence of tuberculosis (TB) disease in Greenland doubled in the 1990s. To combat the increase, national TB interventions were initiated in 2000 and strengthened in 2007. Objective To determine whether the effect of interventions could be detected, we estimated the TB disease risk among children≤15 years before and after interventions were implemented. Design For a study cohort, we recruited all children ≤15 years of age included in the Greenlandic Civil Registration System (CRS) from 1990 to 2010. The CRS identifier was used to link cohort participants with TB cases identified based on the Greenlandic National TB registry. Bacille Calmette Guerin (BCG) vaccination status was identified through year of birth, as BCG was offered to newborns born either before 1991 or after 1996. Years with interventions were defined as 2000–2006 (primary interventions) and 2007–2010 (intensified interventions). Risk of TB was estimated using Poisson regression. Results The study included 35,858 children, of whom 209 had TB disease. The TB disease incidence decreased after interventions were implemented (2007–2010: IRR [incidence rate ratios] 0.62, 95% CI: 0.39–0.95, p=0.03, compared with the 1995–1999 period). The TB disease risk was inversely associated with BCG vaccination (IRR: 0.54, 95% CI: 0.41–0.72, p<0.001). Conclusions Years with national TB interventions in Greenland, including neonate BCG vaccination, are associated with a lower TB disease incidence among children ≤15 years of age. PMID:25045654

    Background: Encephalocele is the protrusion of the cranial contents beyond the normal confines of the skull through a defect in the calvarium and is far less common than spinal dysraphism. The exact worldwide frequency is not known. Aims and Objectives: To determine the epidemiological features, patterns of encephalocele, and its postsurgical results. Materials and Methods: The study was carried from year July 2012 to June 2015. Patients with encephalocele were evaluated for epidemiological characteristics, clinical features, imaging characteristics, and surgical results. Results: 20 encephaloceles patients were treated during the study period. Out of these 12 (60%) were male and 8 (40%) female. Age range was 1 day to 6 years. The most common type of encephalocele was occipital 12 (60%), occipito-cervical 4 (20%), parietal 2 (10%), fronto-nasal 1 (5%), and fronto-naso-ethmoidal 1 (5%). One patient had a double encephalocele (one atretic and other was occipital) with dermal sinus tract and limited dermal myeloschisis. Other associations: Chiari 3 malformation (2), meningomyeloceles (4), and syrinx (4). Three patients presented with rupture two of whom succumbed to meningitis and shock. Seventeen patients treated surgically did well with no immediate surgical mortality (except a case of Chiari 3 malformation who succumbed 6 months postsurgery to unrelated causes). Shunt was performed in 4 cases. Conclusion: The most common type of encephalocele is occipital in our set up. Early surgical management of encephalocele is not only for cosmetic reasons but also to prevent tethering, rupture, and future neurological deficits.

    Background Alopecia areata (AA) is an organ-specific autoimmune disease that typically occurs in young adults. AA in the elderly is relatively rare, thus little data have been reported. Objective This study aimed to understand the clinical characteristics of AA in the elderly. Methods We performed a 10-year retrospective study of AA in the elderly who visited our dermatologic clinic from January 2002 to December 2011. A clinical review of medical records and telephone interviews were performed by two dermatologists. Results Among 1,761 patients with newly diagnosed AA, 61 (3.5%) were older than 60 years at the first visit. Among those who completed a telephone interview, 74.3% (26/35) had less than 50% of scalp-localized hair loss. There was no association between the extent of AA and hair graying (p=0.679). Favorable therapeutic response was observed in 62.9% (22/35) of cases. Conclusion AA in the elderly shows mild disease severity and favorable treatment response. There is no association between graying and the extent of AA. However, the influence of aging on the pathogenesis of AA in the elderly deserves further investigation. PMID:26273157

  9. Wildland fire management and air quality in the southern Sierra Nevada: using the Lion Fire as a case study with a multi-year perspective on PM(2.5) impacts and fire policy.

    PubMed

    Schweizer, Don; Cisneros, Ricardo

    Management of fire is an important and controversial policy issue. Active fire suppression has led to a backlog of fuels, limited the ecological benefits of fire, and reduced short-term smoke impacts likely delaying these emissions to future generations over a larger spatial extent. Smoke impacts can be expected to increase as fire size and intensity increase and the fuel backlog is consumed; whether through reintroduction of fire under desirable conditions or through stand replacing fire. Land Management Agencies would like to increase the use of naturally ignited fires to burn during favorable conditions as a way to reduce catastrophic fires. This study provides information about the levels of air quality impacts expected from these types of fires and discusses some of the policy controversies of managed fire that propagate inconsistencies between agencies and enter the public discourse. The Lion Fire, a primarily low intensity 8,370 ha fire that was extensively monitored for Particulate Matter less than 2.5 microns (PM2.5), is used to quantify impacts to air quality. PM2.5 monitoring sites are used to assess exposure, public health impacts, and subsequently quantify annual air quality during a year with a fire that is within the historic normal fire size and intensity for this area. Ground level PM2.5 impacts were found to be localized with 99% of the hourly Air Quality Index readings in the moderate or good category for the sites impacted by the fire. PM2.5 concentrations at sites nearest the fire were below annual federal air quality standards for PM2.5 with annual 98th percentile at the most impacted sites (Johnsondale, Kernville, and Camp Nelson) of 35.0, 34.0, and 28.0 ?g m(-3) respectively. Smoke impacts to PM2.5 concentrations were not found to reach the populated Central Valley. The findings suggest that this type of fire can be implemented with minimal public health impacts thus allowing an opportunity for air and fire managers to alter policy to allow additional burning in an area with severe anthropogenic air pollution and where frequent widespread fire is both beneficial and inevitable. The more extensive air quality impacts documented with large high intensity fire may be averted by embracing the use of fire to prevent unwanted high intensity burns. A widespread increase in the use of fire for ecological benefit may provide the resiliency needed in Sierra Nevada forests as well as be the most beneficial to public health through the reduction of single dose exposure to smoke and limiting impacts spatially.

    Leiomyosarcoma of the scrotum is a rare genital malignancy with approximately 35 reported cases in literature. We present a case of leiomyosarcoma of the scrotum in a 71-year-old man appearing as a sebaceous cyst that later developed ulcerations. However, because the irregular mass developed ulcerations, this should trigger one to consider that lesion is potentially malignant. The pathology report demonstrated malignant spindle cell neoplasm consistent with leiomyosarcoma, which tested positive for desmin and actin stains. On literature review, a study reported a 5-year survival rate of 50%-80%. The clinical features, diagnosis, histopathologic images, and treatment are reviewed.

    Introduction The thyroid gland is a rare site of clinically detectable tumor metastasis. As thyroid tumors are usually assumed to be primary in origin, its recognition as a secondary is difficult. Presentation of case We report a case of an 80-year old female who was referred to the Department of Surgery for a symptomatic thyroid nodule. Her medical history included a radical nephrectomy for renal cell carcinoma (RCC) nine years ago. During follow-up a pancreatic nodule was noted suggestive of a neuroendocrine tumor and the von Hippel-Lindau syndrome had to be ruled out. The fine-needle aspiration biopsy (FNAB) guided by ultrasound (US) of the thyroid nodule was inconclusive and a hemithyroidectomy and isthmectomy were performed. Histological examination revealed metastasis of a clear cell carcinoma. Discussion RCC disseminates in an unpredictable manner and can show late recurrences. Although secondary involvement of the thyroid gland by RCC is rare, it is still one of the more common neoplasms to metastasize to this site. There are no specific clinical features and few characteristic findings of metastatic thyroid carcinoma on imaging studies. FNAB is a useful procedure to diagnose metastatic thyroid cancer, but one should remain suspicious when the result for malignant cells is negative or indeterminate. After thyroidectomy the diagnosis of RCC is confirmed immunohistochemically. There is a clear survival benefit if a surgical approach to the thyroid metastasis is chosen. Conclusion Thyroid metastasis should be considered in patients with a thyroid nodule and positive history for RCC. PMID:26421840

    Lifestyles and risk factors liable to idiopathic Parkinson's disease (IPD) were evaluated in a case-control study. 95 cases were studied along with their matched (1:2) controls. Cases were diagnosed at the Department of Neurology, Hokkaido University. Each given case was matched to two resident controls according to sex, age (+/- 1 year) and location (residents in the Sapporo area). 218 questions about preclinical life events (diet; exercise and physique; alcohol and smoking; personal relations; personality etc.) were asked in a one-to-one interview conducted by 3 staff members. Univariate results: 1) Diet: From infancy to 40, there were deficient intakes of meat, fruit, milk and dairy products, particularly prior to pubescence. Dietary behaviors after 40 showed no association. 2) Alcohol and smoking: Cases tended to smoke and drink less. 3) Exercise and Physique: Cases were inclined to dislike sports/exercise, to be physically slow, to have poor athletic ability, to have poor flexibility in adolescence and to have fair skin. 4) Personal relations: Cases had a tendency not to read books/newspapers, write letters, use the telephone and visit friends/relatives. Cases also refused leadership roles. 5) Personality: Cases were apt to be unsociable, taciturn, unobliging, and to have slow speech. Multivariate models: In order to study the joint effects and the combined effects of the major variables identified in univariate results, unconditional logistic regression analysis was carried out. The 9 variables were screened using stepwise procedure. From these variables, 4 independent variables were selected: deficient intake of fruit from middle school to 19 years old, fair skin, poor letter-writing ability and unsociability. The 4 independent variables were applied to one model, and resulted in a combined odds ratio figure. When the cases have none of the 4 independent variables, the combined odds ratio figure is 1. If the cases have all of them, then the combined odds ratio figure is 76.25. PMID:8111093

    Reiter's syndrome is one of the rare complications following intravesical bovis Bacillus Calmette-Guerin (BCG) treatment. In this study we have reviewed and discussed 101 cases including our own 6 cases over the past 13 years in Japan (2000-2013). The patients comprised 70 males and 25 females (6 cases were unknown), mean age of 63.1 (range 42 - 91). Arthritis occured 4-5 days after conjunctivitis. Thirty five (55%) of 68 patients needed corticosteroid treatment to control their arthritis. HLA-B27 is known as a risk factor of Reiter's syndrome, however, positive rate was only 2.4% (n = 41).

    2014-01-01

    The primary aim of this paper is to illustrate the strategic and ecological nature of implementation. The ultimate aim of implementation is not dissemination but sustainability beyond the implementation effort. A case study is utilized to illustrate these broad and long-term perspectives of sustainable implementation based on qualitative analyses of a 10-year implementation effort. The purveyors aimed to develop selective community prevention services for children in families burdened by parental psychiatric or addictive problems. Services were gradually disseminated to 23 sites serving 40 municipalities by 2013. Up to 2013, only one site terminated services after initial implementation. Although many sites suspended services for shorter periods, services are still offered at 22 sites. This case analysis is based on project reports, user evaluations, practitioner interviews, and service statistics. The paper focuses on the analyses and strategies utilized to cope with quality decay and setbacks as well as progress and success in disseminating and sustaining the services and their quality. Low-cost multilevel strategies to implement services at the community level were organized by a prevention unit in child psychiatry, supervised by a university department (purveyors). The purveyors were also involved in national and international collaboration and development. Multilevel strategies included manualized intervention, in-practice training methods, organizational responsibility, media strategies, service evaluation, staff motivation maintenance, quality assurance, and proposals for new law regulations. These case history aspects will be discussed in relation to the implementation literature, focusing on possible applicability across settings. PMID:24944878

    The integration of evidence into reflective health care practice has been on the rise in recent years and is a phenomenon that has affected all health care professions, including massage therapy. Clinical case studies are a research design that follows one patient or subject, making the studies ideal for use in clinical practice. They are valuable for communicating information from clinical practice to the broader community. Case studies have face validity that may be more valuable to individual practitioners than homogeneous randomized controlled trials, as the practitioner may recognize a complex patient in the case report. At Humber College, Student Massage Therapists (SMTs) create, conduct, and communicate results of a clinical case study prior to graduation. This article describes the process and experience.

    2010-02-01

    Many faculty members consider using case studies but not all end up using them. We provide a brief review of what cases are intended to do and identify three ways in which they can be used. We then use an example to illustrate how we have used the case study method in teaching business demography. Among other benefits, we note that the case studies method not only encourages the acquisition of skills by students, but can be used to promote "deep structure learning," an approach naturally accommodates other features associated with the case studies method-the development of critical thinking skills, the use of real world problems, the emphasis of concepts over mechanics, writing and presentation skills, active cooperative learning and the "worthwhileness" of a course. As noted by others, we understand the limitations of the case study method. However, given its strengths, we believe it has a place in the instructional toolbox for courses in business demography. The fact that courses we teach is a testament to our perceived efficacy of this tool. PMID:20190858

    Background Countries in the different stages of pre-elimination, elimination, and prevention of reintroduction are required to report the number of indigenous and imported malaria cases to the World Health Organization (WHO). However, these data have not been systematically analysed at the global level. Objective For the period 2007 to 2013, we aimed to report on 1) the proportion of countries providing data on the origin of malaria cases and 2) the origin of malaria cases in countries classified as being in the stages of pre-elimination, elimination and prevention of reintroduction. Design An observational study using annual data reported through routine health information systems to the WHO Global Malaria Programme between 2007 and 2013. Results For all countries classified as being in pre-elimination, elimination, and prevention of reintroduction in the year 2013, there has been a substantial decrease in the total number of indigenous malaria cases, from more than 15,000 cases reported in 2007 to less than 4,000 cases reported in 2013. However, the total number of imported malaria cases has increased over that time period, from 5,600 imported cases in 2007 to approximately 6,800 in 2013. Conclusions Vigilant monitoring of the numbers of imported and indigenous malaria cases at national and global levels as well as appropriate strategies to target these cases will be critical to achieve malaria eradication.
