30 years of ergonomics at 3M: a case study.  

PubMed

The added value of the Ergonomics Program at 3M was found to be improved employee safety, compliance with regulations and reduction of work-related illness, increases in productivity, and quality and operating efficiency. This paper describes the thirty years of existence of this program. For the first twenty years, the program objectives were to: respond to requests for assistance related to work-related musculoskeletal disorder (WMSD) concerns, raise employee awareness of MSDs and ergonomics; educate engineers in ergonomics design; and develop ergonomics teams at manufacturing locations. Since the year 2000, 3M's Ergonomics Program has been in transition from a US-centric and corporate-based technical-expertled program to a global program applying participatory ergonomics strategies within a macroergonomics framework. During that transition, the existing program requirements were revised, new methods and program tools were created, and expectations for implementation at the manufacturing locations clarified. This paper focuses on the company's manufacturing ergonomics program activities during the past ten years and includes specifics of the program's objectives, risk assessment reduction process, and ergonomics technical expertise development. The main benefit achieved throughout the company is reducing employee injury while also increasing productivity and operating efficiency. PMID:22317510

Case study of a spinal epidural capillary hemangioma: a 4-year postoperative follow-up.  

PubMed

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.

Study of Desert Dust Events over the Southwestern Iberian Peninsula in Year 2000: Two Case Studies  

SciTech Connect

Strong desert dust events occurring in 2000 over the southwestern Atlantic coast of the Iberian Peninsula are detected and evaluated by means of the TOMS Aerosol Index (A.I.) at three different sites, Funchal (Madeira Island, Portugal), Lisboa (Portugal), and El Arenosillo (Huelva, Spain). At the El Arenosillo station, measurements from an AERONET Cimel sunphotometer allow more retrieval of the spectral AOD and the derived alpha ''angstrom'' coefficient. After using different threshold values of these parameters, we conclude that it is difficult to establish reliable and robust criteria for an automatic estimation of the number of dust episodes and the total number of dusty days per year. As a result, additional information, such as airmass trajectories, were used to improve the estimation, from which reasonable results were obtained (although some manual editing was still needed). A detailed characterization of two selected desert dust episodes, a strong event in winter and another of less intensity in summer, was carried out using AOD derived from Brewer spectrometer measurements. Size distribution parameters and radiative properties, such as refractive index and the aerosol single scattering albedo derived from Cimel data, were analyzed in detail for one of these two case studies. Although specific to this dust episode, the retrieved range of values of these parameters clearly reflect the characteristics of desert aerosols. Back-trajectory analysis, synoptic weather maps and satellite images were also considered together, as supporting data to assess the aerosol desert characterization in this region of study.

Multiple personality. A single case study with a 15 year follow-up.  

PubMed

A review of the literature relating to multiple personality is presented together with a study of a single case of hysterical aetiology that demonstrates the development of multiple personality from a fugue amnesic state. A re-examination of this case after 15 years without significant psychotherapeutic intervention demonstrates a tendency towards remission. The view that multiple personality is a form of fugue, not necessarily hysterical, in which an alternative personality is adopted and that this behaviour is reinforced by the attention that it receives, is discussed.

Propeller Flaps and Its Outcomes - A Prospective Study of 15 Cases Over Two-years.  

PubMed

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

The Epidemiology and Clinical Spectrum of Melioidosis: 540 Cases from the 20 Year Darwin Prospective Study  

PubMed Central

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.

Physiological and anthropometric progression in an international oarsman: a 15-year case study.  

PubMed

Purpose: In this case study, a world-class rower was followed over a period of 15 y in which he evolved from junior to professional athlete. Methods: An incremental exercise test and a 2000-m ergometer test were performed each year in the peak period of the season starting at the age of 16 y. In addition, the training logs of 1 y each as a junior and a senior rower were recorded and analyzed. Results: Maximal oxygen uptake (VO2max), maximal power output (Pmax), and power output at 4 mmol/L blood lactate concentration increased until the age of 27 and then stabilized at 30 y at 6.0 ± 0.2 L/min, 536 ± 15 W, and 404 ± 22 W, respectively. At the age of 27-28 y the rower also had a career-best 2000-m ergometer test (5?58?) and on-water performance with a 4th place at the Olympic Games (2008) in Beijing and World Championships (2009). At the age of 23 y, the rower trained a total of 6091 km in 48 wk. Of the total training time, 15.4% consisted of general training practices, 23.4% resistance training, and 61.2% specific rowing training. Conclusion: The on-water performance in the World Championships and Olympic Games corresponded closely to the evolution in the rower's physiological profile and 2000-m ergometer performance. The long-term build-up program resulted in an increase in the physiological parameters up to the age of 27 y and resulted in a 4th position at the 2008 Olympic Games at a body mass of only 86 kg.

Haematogenous Staphylococcus aureus meningitis. A 10-year nationwide study of 96 consecutive cases  

PubMed Central

Background Haematogenous Staphylococcus aureus meningitis is rare but associated with high mortality. Knowledge about the disease is still limited. The objective of this study was to evaluate demographic and clinical prognostic features of bacteraemic S. aureus meningitis. Methods Nationwide surveillance in Denmark from 1991 to 2000 with clinical and bacteriological data. Risks of death were estimated by Cox proportional hazards regression analysis. Results Among 12480 cases of S. aureus bacteraemia/sepsis, we identified 96 cases of non-surgical bacteraemic S. aureus meningitis (0.8%). Incidence rates were 0.24 (95% confidence interval [CI], 0.18 to 0.30)/100 000 population between 1991–1995 and 0.13 (CI, 0.08 to 0.17)/100 000 population between 1996–2000. Mortality was 56%. After adjustment, only co morbidity (hazard ratio [HR], 3.45; CI, 1.15 to 10.30) and critical illness (Pitt score ? 4) (HR, 2.14; CI, 1.09 to 4.19) remained independent predictors of mortality. Conclusion The incidence, but not mortality of bacteraemic S. aureus meningitis decreased during the study period. Co morbidity and critical illness were independent predictors of a poor outcome.

Forty-five years of open plan office experience: An unusual case study  

NASA Astrophysics Data System (ADS)

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.

Effect of 35 years beta-adrenergic blockade therapy on autonomic cardiovascular modulation. A case study.  

PubMed

The influence of long duration beta-blockade on autonomic and cardiovascular function remains not completely understood. The aim of this study was to evaluate the effect of long duration beta-adrenergic blockade treatment for hypertension control, on autonomic cardiovascular control in a 78-year-old male patient in relation to population findings. Heart rate variability was determined in the frequency domain (Total power, low frequency power and high frequency power), during baseline (supine and standing) and during 24 hour Holter recording. Results were compared with heart rate and heart rate variability data obtained from a normal healthy male population as a function of age. Circadian rhythm remained present. Heart rate during daytime was lower compared to the population group. None of the heart rate variability parameters were different from the normal population age group. Our results show that after 35 years of beta-blockade treatment, autonomic modulation of cardiac function remains within normal limits for that age group. Blood pressure remained at the higher limits (120-150/60-80 mmHg), but under control. PMID:20101873

Declining 1-year case-fatality of stroke and increasing coverage of vascular risk management: population-based cohort study  

PubMed Central

Background The authors estimated trends in 1-year case-fatality of stroke in relation to changes in vascular risk management from 1997 to 2005. Methods A cohort study was implemented using data for 407 family practices in the UK General Practice Research Database, including subjects with first acute strokes between 1997 and 2005. One-year case-fatality was estimated by year and sex. Rate ratios were estimated using Poisson regression. Results There were 19?143 women and 16?552 men who had first acute strokes between 1997 and 2005. In women, the 1-year case-fatality declined from 41.2% in 1997 to 29.2% in 2005. In men, the decline was from 29.2% in 1997 to 22.2% in 2005. The proportion of general practices that prescribed antihypertensive drugs to two-thirds or more of new patients with stroke increased from 6% in 1997 to 48% in 2005, for statins from 1% to 39% and for antiplatelet drugs from 11% to 39%. The rate ratio for 1-year mortality in 2005, compared with 1997–1998, adjusted for age group, sex, prevalent coronary heart disease, prevalent hypertension and deprivation quintile was 0.79 (0.74 to 0.86, p<0.001). After adjustment for antihypertensive, statin and antiplatelet prescribing, the rate ratio was 1.29 (1.17 to 1.42). Conclusions Reducing 1-year case-fatality after acute stroke may be partly explained by increased prescribing of antihypertensive, statin and antiplatelet drugs to patients with recent strokes. However, these analyses did not include measures of possible changes over time in stroke severity or acute stroke management.

Sporadic community-acquired Legionnaires' disease in France: a 2-year national matched case-control study.  

PubMed

Legionnaires' disease (LD) is an aetiology of community-acquired bacterial pneumonia in adults, with a high case-fatality ratio (CFR). We conducted a matched case-control study to identify risk factors for sporadic, community-acquired LD. Cases of sporadic, community-acquired and biologically confirmed LD, in metropolitan France from 1 September 2002 to 31 September 2004, were matched with a control subject according to age, sex, underlying illness and location of residence within 5 km. We performed a conditional logistic regression on various host-related factors and exposures. Analysis was done on 546 matched pairs. The CFR was 3.5%. Age ranged from 18-93 years (mean 57 years), with a 3.6 male:female sex ratio. Cases were more likely to have smoked with the documentation of a dose-effect relation, to have travelled with a stay in a hotel (OR 6.1, 95% CI 2.6-14.2), or to have used a wash-hand basin for personal hygiene (OR 3.5, 95% CI 1.6-7.7) than controls. Tobacco and travel have been previously described as risk factors for LD, but this is the first time that such a dose-effect for tobacco has been documented among sporadic cases. These findings will provide helpful knowledge about LD and help practitioners in identifying patients at high risk. PMID:18211725

SUMMARY Legionnaires' disease (LD) is an aetiology of community-acquired bacterial pneumonia in adults, with a high case-fatality ratio (CFR). We conducted a matched case-control study to identify risk factors for sporadic, community-acquired LD. Cases of sporadic, community-acquired and biologically confirmed LD, in metropolitan France from 1 September 2002 to 31 September 2004, were matched with a control subject according to age, sex, underlying illness and location of residence within 5 km. We performed a conditional logistic regression on various host-related factors and exposures. Analysis was done on 546 matched pairs. The CFR was 3·5%. Age ranged from 18–93 years (mean 57 years), with a 3·6 male:female sex ratio. Cases were more likely to have smoked with the documentation of a dose-effect relation, to have travelled with a stay in a hotel (OR 6·1, 95% CI 2·6–14·2), or to have used a wash-hand basin for personal hygiene (OR 3·5, 95% CI 1·6–7·7) than controls. Tobacco and travel have been previously described as risk factors for LD, but this is the first time that such a dose-effect for tobacco has been documented among sporadic cases. These findings will provide helpful knowledge about LD and help practitioners in identifying patients at high risk.

Building Strong Geoscience Departments: Case Studies and Findings from Six Years of Programming  

NASA Astrophysics Data System (ADS)

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.

The spatial distribution of leprosy cases during 15 years of a leprosy control program in Bangladesh: An observational study  

PubMed Central

Background An uneven spatial distribution of leprosy can be caused by the influence of geography on the distribution of risk factors over the area, or by population characteristics that are heterogeneously distributed over the area. We studied the distribution of leprosy cases detected by a control program to identify spatial and spatio-temporal patterns of occurrence and to search for environmental risk factors for leprosy. Methods The houses of 11,060 leprosy cases registered in the control area during a 15-year period (1989–2003) were traced back, added to a geographic database (GIS), and plotted on digital maps. We looked for clusters of cases in space and time. Furthermore, relationships with the proximity to geographic features, such as town center, roads, rivers, and clinics, were studied. Results Several spatio-temporal clusters were observed for voluntarily reported cases. The cases within and outside clusters did not differ in age at detection, percentage with multibacillary leprosy, or sex ratio. There was no indication of the spread from one point to other parts of the district, indicating a spatially stable endemic situation during the study period. The overall risk of leprosy in the district was not associated with roads, rivers, and leprosy clinics. The risk was highest within 1 kilometer of town centers and decreased with distance from town centers. Conclusion The association of a risk of leprosy with the proximity to towns indicates that rural towns may play an important role in the epidemiology of leprosy in this district. Further research on the role of towns, particularly in rural areas, is warranted.

Creating Innovative Research Designs: The 10-Year Methodological Think Tank Case Study  

PubMed Central

PURPOSE Addressing important but complex research questions often necessitates the creation of innovative mixed methods designs. This report describes an approach to developing research designs for studying important but methodologically challenging research questions. METHODS The Methodological Think Tank has been held annually in conjunction with the Primary Care Research Methods and Statistics Conference in San Antonio since 1994. A group of 3 to 4 methodologists with expertise balanced between quantitative and qualitative backgrounds is invited by the think tank coordinators to serve on a 2-day think tank to discuss a research question selected from those submitted in response to a call for proposals. During the first half-day, these experts explore the content area with the investigator, often challenging beliefs and assumptions. During the second half-day, the think tank participants systematically prune potential approaches until a desirable research method is identified. RESULTS To date, the most recent 7 think tanks have produced fundable research designs, with 1 being funded by a K award and 4 by R01 grants. All participating investigators attributed much of their success to think tank participation. Lessons learned include (1) the importance of careful selection of participating methodologists, (2) all think tank communities of inquiry must go through 4 stages of development from pseudocommunity to community, and (3) the critical importance of listening by the investigator. CONCLUSION Researchers and academic departments could use this process locally to develop innovative research designs.

PubMed Central

Background A retrospective study concerning patients presenting with patella instability, treated using a Roux-Elmslie-Trillat reconstruction operation and followed up for 10 years following surgery, is presented. Methods Pre-operative and follow-up radiographic evaluation included the weight-bearing anteroposterior and merchant views. Evaluation was carried out using the Insall-Salvati index, sulcus and congruence angle. The Roux-Elmslie-Trillat reconstruction operation was performed on 18 patients. The clinical evaluation at follow-up was performed using the Knee-Society-Score (KSS) and Tegner-Score. Results Subjective results of the operation were classed as excellent or good in 16 of the 18 patients ten years after surgery; persistent instability of the patella was recorded in only one of the 18 patients. The majority of patients returned to the same level of sporting activity after surgery as they had participated in before injury. Conclusions The Roux-Elmslie-Trillat procedure could be recommended in cases presenting with an increased q-angle, trochlea dysplasia or failed soft tissue surgery. In the present study the majority of patients report a return to previous sporting activity ten years after surgery.

Prediction of 7-year psychopathology from mother-infant joint attention behaviours: a nested case-control study  

PubMed Central

Background To investigate whether later diagnosis of psychiatric disorder can be predicted from analysis of mother-infant joint attention (JA) behaviours in social-communicative interaction at 12 months. Method Using data from a large contemporary birth cohort, we examined 159 videos of a mother-infant interaction for joint attention behaviour when children were aged one year, sampled from within the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Fifty-three of the videos involved infants who were later considered to have a psychiatric disorder at seven years and 106 were same aged controls. Psychopathologies included in the case group were disruptive behaviour disorders, oppositional-conduct disorder, attention-deficit/hyperactivity disorder, pervasive development disorder, anxiety and depressive disorders. Psychiatric diagnoses were obtained using the Development and Wellbeing Assessment when the children were seven years old. Results None of the three JA behaviours (shared look rate, shared attention rate and shared attention intensity) showed a significant association with the primary outcome of case–control status. Only shared look rate predicted any of the exploratory sub-diagnosis outcomes and was found to be positively associated with later oppositional-conduct disorders (OR [95% CI]: 1.5 [1.0, 2.3]; p?=?0.041). Conclusions JA behaviours did not, in general, predict later psychopathology. However, shared look was positively associated with later oppositional-conduct disorders. This suggests that some features of JA may be early markers of later psychopathology. Further investigation will be required to determine whether any JA behaviours can be used to screen for families in need of intervention.

Exposure to air pollutants and mortality in hypertensive patients according to demography: A 10 year case-crossover study.  

PubMed

This study evaluated whether short term exposures to NO2, O3, particulate matter <10 mm in diameter (PM10) were associated with higher risk of mortality. A total of 223,287 hypertensive patients attended public health-care services and newly prescribed at least 1 antihypertensive agent were followed-up for up to 5 years. A time-stratified, bi-directional case-crossover design was adopted. For all-cause mortality, significant positive associations were observed for NO2 and PM10 at lag 0-3 days per 10 ?g/m(3) increase in concentration (excess risks 1.187%-2.501%). Significant positive associations were found for O3 at lag 1 and 2 days and the excess risks were 1.654% and 1.207%, respectively. We found similarly positive associations between these pollutants and respiratory disease mortality. These results were significant among those aged ?65 years and in cold seasons only. Older hypertensive patients are susceptible to all-cause and respiratory disease-specific deaths from these air pollutants in cold weather. PMID:24953346

Circulating Angiopoietin-2 levels predict mortality in kidney transplant recipients: a 4-year prospective case-cohort study.  

PubMed

Angiopoietin 2 (Angpt2) impairs endothelial function by preventing angiopoietin 1 from binding to their common endothelial-specific receptor Tie2. Here, we examined whether circulating Angpt2 predicts outcome in kidney transplant recipients. For this case-cohort study, we selected 130 kidney transplant recipients who had died or returned to dialysis within the first 2 years of follow-up of our cohort study, as well as 130 age- and gender-matched kidney transplant recipients without an event (controls) from a total of 993 kidney transplant recipients. The total of 260 selected patients were followed in median 4 years. Serum Angpt2 at baseline was measured using an in-house immunoluminometric assay. Median Angpt2 concentrations were significantly higher in patients who died [median (interquartile range--IQR) 3.6 (2.8-5.9) ng/ml] as compared to patients who did not die during the study period [2.8 (2.1-4.1) ng/ml; P < 0.001]. Ln (natural log) Angpt2 levels correlated positively with C-reactive protein levels (r = 0.315, P < 0.001) and the Charlson Comorbidity Index (r = 0.188, P = 0.002) and were inversely associated with eGFR (r = -0.301, P < 0.001) hemoglobin (r = -0.269, P < 0.001), and serum albumin concentrations (r = -0.382, P < 0.001). On multivariate analyses, baseline Angpt2 levels independently predicted all-cause mortality (multivariable-adjusted hazard ratio associated with one natural log unit higher Angpt2 level: 1.70 (95% confidence interval: 1.10-2.61)). In our analysis, circulating Angpt2 was an independent predictor of all-cause mortality in stable, prevalent kidney transplant recipients. PMID:24628855

The results from a two-year case study of an information and communication technology support system for family caregivers.  

PubMed

Abstract Purpose: The aim was to better understand how information and communication technology (ICT) can provide support to elderly family caregivers caring for significant others suffering from dementia or stroke. Method: Ten households equipped with an ICT system, with a family caregiver and a spouse diagnosed with dementia or stroke, were followed and observed in a two-year case study. The family caregivers had regular meetings in groups organised by the municipal care of the elderly. Data from observations, semi-structured interviews, user data from the ICT system and data about the support provided by the municipality has been used to validate the findings. Results: The family caregivers socialised with users in the group as long as the users were stayed in the group. Meetings in the group were an important opportunity for exchanging experiences and to easing one"s mind. The ICT system did not reduce the municipality"s level of services to the participating families. The information built into the system has to be constantly updated to be of interest. Conclusions: An ICT support must be provided in a context of personal meetings and with a formal caregiver backing. This will empower informal or family caregivers. Such support must give the user the possibility to communicate and get access to the Internet. Implications for Rehabilitation Benefits were obtained when informal caregivers met with a group of people with whom they share the same kind of experiences and were supported by a formal caregiver. Informal caregivers need more attention and recognition. ICT systems can help but must be current and maintain the users interest. PMID:23855387

Cervical Screening at Age 50-64 Years and the Risk of Cervical Cancer at Age 65 Years and Older: Population-Based Case Control Study  

PubMed Central

Background There is little consensus, and minimal evidence, regarding the age at which to stop cervical screening. We studied the association between screening at age 50–64 y and cervical cancer at age 65–83 y. Methods and Findings Cases were women (n?=?1,341) diagnosed with cervical cancer at age 65–83 y between 1 April 2007 and 31 March 2012 in England and Wales; age-matched controls (n?=?2,646) were randomly selected from population registers. Screening details from 1988 onwards were extracted from national databases. We calculated the odds ratios (OR) for different screening histories and subsequent cervical cancer. Women with adequate negative screening at age 65 y (288 cases, 1,395 controls) were at lowest risk of cervical cancer (20-y risk: 8 cancers per 10,000 women) compared with those (532 cases, 429 controls) not screened at age 50–64 y (20-y risk: 49 cancers per 10,000 women, with OR?=?0.16, 95% CI 0.13–0.19). ORs depended on the age mix of women because of the weakening association with time since last screen: OR?=?0.11, 95% CI 0.08–0.14 at 2.5 to 7.5 y since last screen; OR?=?0.27, 95% CI 0.20–0.36 at 12.5 to 17.5 y since last screen. Screening at least every 5.5 y between the ages 50 and 64 y was associated with a 75% lower risk of cervical cancer between the ages 65 and 79 y (OR?=?0.25, 95% CI 0.21–0.30), and the attributable risk was such that in the absence of screening, cervical cancer rates in women aged 65+ would have been 2.4 (95% CI 2.1–2.7) times higher. In women aged 80–83 y the association was weaker (OR?=?0.49, 95% CI 0.28–0.83) than in those aged 65–69 y (OR?=?0.12, 95% CI 0.09–0.17). This study was limited by an absence of data on confounding factors; additionally, findings based on cytology may not generalise to human papillomavirus testing. Conclusions Women with adequate negative screening at age 50–64 y had one-sixth of the risk of cervical cancer at age 65–83 y compared with women who were not screened. Stopping screening between ages 60 and 69 y in women with adequate negative screening seems sensible, but further screening may be justifiable as life expectancy increases.

Quality of life after laparoscopic gastric banding: Prospective study (152 cases) with a follow-up of 2 years.  

PubMed

To evaluate influence of laparoscopic gastric banding (LGB) on quality of life (QOL) in patients with morbid obesity. Laparoscopic adjustable gastric banding is a popular bariatric operation in Europe. The objectives of surgical therapy in patients with morbid obesity are reduction of body weight, and a positive influence on the obesity-related comorbidity as well the concomitant psychologic and social restrictions of these patients. In a prospective clinical trial, development of the individual patient QOL was analyzed, after LGB in patients with morbid obesity. From October 1999 to January 2001, 152 patients [119 women, 33 men, mean age 38.4 y (range 24 to 62), mean body mass index 44.3 (range 38 to 63)] underwent evaluation for LGB according the following protocol: history of obesity; concise counseling of patients and relative on nonsurgical treatment alternatives, risk of surgery, psychologic testing, questionnaire for eating habits, necessity of lifestyle change after surgery; medical evaluation including endocrinologic and nutritionist work-up, upper GI endoscopy, evaluation of QOL using the Gastro Intestinal Quality of Life Index (GIQLI). Decision for surgery was a multidisciplinary consensus. This group was follow-up at least 2 years, focusing on weight loss and QOL. Mean operative time was 82 minutes; mean hospital stay was 2.3 days and the mean follow-up period was 34 months. The BMI dropped from 44.3 to 29.6 kg/m and all comorbid conditions improved markedly: diabetes melitus resolved in 71% of the patients, hypertension in 33%, and sleep apnea in 90%. However, 26 patients (17%) had late complications requiring reoperation. Preoperative global GIQLI score was 95 (range 56 to 140), significant different of the healthy volunteers score (120) (70 to 140) P < 0.001. Correlated with weight loss (percentage loss of overweight and BMI), the global score of the group increased to 100 at 3 months, 104 at 6, 111 at 1 year to reach 119 at 2 years which is no significant different of healthy patients. Analyzing the subscale, physical condition, emotional status, and social integration increased significantly (P < 0.001) from preoperative to end of follow-up. Digestive symptoms were not modified. In case of failure of the procedure (10.5%) global Giqli score is not modified. Patients who have required successful revisional surgery for late complications (6.5%) have an excellent QOL outcome that are not different from the whole group. Together with a satisfactory reduction of the excess overweight, laparoscopic gastric banding may lead in a carefully selected population of patients with morbid obesity to a significant improvement of patient QOL, in at least 2 years follow-up.

Oral Health in 4-6 Years Children with Cleft Lip/Palate: A Case Control Study  

PubMed Central

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.

[First permanent molar caries: a case study of Moroccan children between 6 and 15 year-old].  

PubMed

It is a transverse descriptive study realized from clinical files of 100 Moroccan children aged between 6 and 15 year-old having consulted the Rabat Dental Hospital (U.T.H. Ibn Sina) in Morocco between January and December 2009. The criteria of inclusion are age, Moroccan origin, first four permanent molars having made their eruption and a complete clinical file. The criteria of exclusion are the non-eruption of a first permanent molar and an incomplete clinical file. The clinical parameters are: age, sex, tooth brushing, quality of alimentation and the condition of the first permanent molars (caries, extraction, filling). The results showed that 65% of the children between 6 and 15 years have at least a first decayed permanent molar. Eight per cent of the children have at least a filling material on the first permanent molar and 4% of the children have already extracted a first permanent molar. The caries touch both sexes, both right and left sectors and both superior and lower arches without statistically significant difference (p > 0.05). The presence of the caries increased, on the other hand, with the age (p < 0.05). The relation between presence of caries, tooth brushing and quality of alimentation is not significant (p < 0.05). These results are in accordance with numerous studies and show a particular cario-sensibility of the first permanent molar. PMID:23513507

Global functioning and suicide among Chinese rural population aged 15-34 years: a psychological autopsy case-control study.  

PubMed

As the relationship between global functioning and young suicide remains unclear in rural China, this study was aimed to explore the relationship between them. Data of 391 rural suicides and 416 controls, all aged 15-34 years in three provinces in China were used for this study. The Global Assessment of Functioning (GAF) scale was adopted to assess global functioning of suicides and controls. The results showed that GAF score was stronger than mental illness in predicting suicide in China. Different correlates of GAF score were found between suicides and controls. Unsurprisingly, GAF score was significantly correlated with mental illness in both suicides and controls. Different characteristics were also found among three types of suicide which were classified using GAF score. Assessing global functioning is useful and GAF scale should be regularly used in suicide prevention practice. PMID:22150171

'Putting it together': unfolding case studies and high-fidelity simulation in the first-year of an undergraduate nursing curriculum.  

PubMed

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.

Zanoli's procedure for overlapping fifth toe: retrospective study of 18 cases followed for 4-17 years.  

PubMed

Digitus quintus superductus pedis (overlapping fifth toe) is a congenital deformity, often bilateral, in which the fifth toe is medially directed, rotated and hyperextended. There is no consensus regarding the best treatment. We describe our experience using Zanoli's procedure, which is a tenodesis procedure using the extensor tendon of the fifth toe. Between 1979 and 1993, we operated on 16 patients (7 bilateral, total 23 feet). 13 (10 women) patients (18 feet), with a mean age of 26 (19-40) years, were seen on follow-up. The mean follow-up time was 8 (4-17) years. Pain relief was achieved in all patients. From the surgeon's point of view, 3 toes overcorrected due to technical errors were considered unsatisfactory. All patients, however, were satisfied with the result and would advise other patients to undergo the same operation. PMID:9855233

Student effort expectations and their learning in first-year introductory physics: A case study in Thailand  

NASA Astrophysics Data System (ADS)

The Maryland Physics Expectations (MPEX) survey was designed to probe students’ expectations about their understanding of the process of learning physics and the structure of physics knowledge—cognitive expectations. This survey was administered to first-year university students in Thailand in the first semester of an introductory calculus-based physics course during academic years 2007 and 2008, to assess their expectations at the beginning of the course. The precourse MPEX results were compared and correlated with two separate measures of student learning: (1) individual students’ normalized gains from pre and post Force and Motion Conceptual Evaluation (FMCE) results, which measure students’ conceptual understanding, and (2) student’s scores on the final exam, which measure their more general problem-solving ability. The results showed a significant positive correlation between their overall MPEX score and five of the six MPEX cluster scores, with their normalized learning gains on the FMCE for both academic years. The results also showed significant positive correlations between student MPEX scores and their final exam scores for the overall MPEX score and all MPEX cluster scores except for the effort cluster. We interviewed two groups of five students each, one group with small favorable scores on the precourse MPEX effort cluster and one with high favorable scores on the precourse MPEX effort cluster, to see how the students’ learning efforts compared with their MPEX results. We concluded from the interviews that what the students think or expect about the MPEX effort involved in learning physics does not match what they actually do.

Iron deficiency screening in the first three years of life: A three-decade-long retrospective case study.  

PubMed

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

Although the definitive cause of infantile hypertrophic pyloric stenosis is unknown, it's probable that several predisposing risk factors would be associated with the condition. We analysed some perinatal factors in relation to the incidence of infantile hypertrophic pyloric stenosis among children observed during the period 1970-90. We examined 61 infants with surgically confirmed hypertrophic pyloric stenosis and, as controls, 61 healty children comparable for age. In every child we studied: sex, birth rank, pregnancy and delivery, birthweight, parental age, type of feeding, familial history of hypertrophic pyloric stenosis and of atopy, seasonal variation in incidence, AB0 and Rh blood phenotypes. In the 61 infants with hypertrophic pyloric stenosis, the incidence of three factors (male sex, primogeniture and feeding with artificial milk) was significantly higher than that in the controls. We conclude that infantile hypertrophic pyloric stenosis probably has a particular genetic basis, but perinatal factors are responsible for the rising of the condition. However the true aetiology remains to be elucidated. PMID:1461785

Results of the cementless Plasmacup in revision total hip arthroplasty: a retrospective study of 72 cases with an average follow-up of eight years  

PubMed Central

Background There are multiple revision implant systems currently available for socket revision in revision total hip arthroplasty. Up until now, not all of these systems have been followed up with regards to their long-term use as a revision implantation. For the first time, this study presents the hemispherical porous-coated socket Plasmacup SC, produced by Aesculap, Tuttlingen, Germany, and the clinical and radiological mid-term results of this revision cup implant. Methods Over a period of ten years the Plasmacup SC press-fit-cup was used as a revision implant in 72 consecutive aseptic cases which were included in this retrospective study. The mean follow-up period was 8 years. Bone graft transplantation was performed in 32% of all cases. In 90%, the cup was fixed with additional screws. The follow-up radiographs were analysed with regards to cup migration, osteointegration and osteolysis in the DeLee zones using a computer aided program taking the teardrop figure as a main point of reference. For clinical evaluation the Harris-Hip-Score and the WOMAC-Score were utilized. Results At the follow up examination, the mean Harris-Hip-Score was 83.5 points and the mean WOMAC-Score 34.7 points. 93% of all patients were satisfied with the result of the operation. No aseptic cup loosening could be observed and only one cup had to be removed due to infection. No significant longitudinal or transversal cup migration could be observed. Conclusion Aesculap's Plasmacup SC is suitable as a cementless cup revision implant. There is stable cup osteointegration, post press-fit implantation, even in the case of major acetabular bone defects.

A new prognostic clinicopathological classification of pituitary adenomas: a multicentric case-control study of 410 patients with 8 years post-operative follow-up.  

PubMed

Pituitary adenomas are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation. This retrospective multicentric case-control study comprised 410 patients who had surgery for a pituitary tumour with long-term follow-up. Using pituitary magnetic resonance imaging for diagnosis of cavernous or sphenoid sinus invasion, immunocytochemistry, markers of the cell cycle (Ki-67, mitoses) and p53, tumours were classified according to size (micro, macro and giant), type (PRL, GH, FSH/LH, ACTH and TSH) and grade (grade 1a: non-invasive, 1b: non-invasive and proliferative, 2a: invasive, 2b: invasive and proliferative, and 3: metastatic). The association between patient status at 8-year follow-up and age, sex, and classification was evaluated by two multivariate analyses assessing disease- or recurrence/progression-free status. At 8 years after surgery, 195 patients were disease-free (controls) and 215 patients were not (cases). In 125 of the cases the tumours had recurred or progressed. Analyses of disease-free and recurrence/progression-free status revealed the significant prognostic value (p < 0.001; p < 0.05) of age, tumour type, and grade across all tumour types and for each tumour type. Invasive and proliferative tumours (grade 2b) had a poor prognosis with an increased probability of tumour persistence or progression of 25- or 12-fold, respectively, as compared to non-invasive tumours (grade 1a). This new, easy to use clinicopathological classification of pituitary endocrine tumours has demonstrated its prognostic worth by strongly predicting the probability of post-operative complete remission or tumour progression and so could help clinicians choose the best post-operative therapy.

Risk factors for scald injury in children under 5 years of age: a case-control study using routinely collected data.  

PubMed

Scald injury is common, accounting for half of all burns in pre-school children. Most scalds are preventable and health professionals can play an important role in targeting interventions to those at greatest risk. However, the potential for routinely collected medical data to be used to identify high risk children has not been well explored. We used a matched case-control study to identify risk factors for first scald injury in children under 5 using a large, nationally representative database of routinely collected primary care records. Among 986 cases and 9240 controls, male gender, age (2 years), higher birth order, single-parent families and increasing index of material deprivation were associated with increased odds of scald injury. Older maternal age at childbirth was associated with decreased odds of scald injury. Children at risk of scald injury can be identified from routinely collected primary care data and primary care practitioners can use this information to target evidence-based safety interventions.

The predictive validity of the 10/66 Dementia diagnosis in Chennai, India - a three year follow-up study of cases identified at baseline  

PubMed Central

INTRODUCTION: Dementia prevalence according to DSM-IV criteria tends to be very low in less developed settings. The 10/66 Dementia Research Group's cross-culturally validated diagnosis returns a considerably higher prevalence. Assessing the predictive validity of the 10/66 dementia diagnosis will assist in establishing the best criterion for estimating the population burden of dementia. METHODS: In a population-based study in Chennai, India, we aimed to follow up after three years 75 people with 10/66 dementia and 193 with cognitive impairment but no dementia (CIND), reassessing diagnostic status, clinical severity, cognitive function, disability and needs for care. RESULTS: We traced 54 people with dementia of whom 25 (46.3%) had died, double the mortality rate among those with CIND. Twenty-two of the 24 people with 10/66 dementia that were re-examined still met 10/66 dementia criteria. There was clear evidence of clinical progression and increased needs for care. Only one ‘case’ had unambiguously improved. Cognitive function had deteriorated and disability increased to a much greater extent than among those with CIND. CONCLUSION: The strong predictive validity of the 10/66 dementia diagnosis is consistent with a lack of sensitivity of the DSM-IV criterion to mild to moderate cases, which may underestimate prevalence in less developed regions.

A Randomized Trial Comparing Telemedicine Case Management with Usual Care in Older, Ethnically Diverse, Medically Underserved Patients with Diabetes Mellitus: 5 Year Results of the IDEATel Study  

PubMed Central

Context Telemedicine is a promising but largely unproven technology for providing case management services to patients with chronic conditions and lower access to care. Objectives To examine the effectiveness of a telemedicine intervention to achieve clinical management goals in older, ethnically diverse, medically underserved patients with diabetes. Design, Setting, and Patients A randomized controlled trial was conducted, comparing telemedicine case management to usual care, with blinded outcome evaluation, in 1,665 Medicare recipients with diabetes, aged ? 55 years, residing in federally designated medically underserved areas of New York State. Interventions Home telemedicine unit with nurse case management versus usual care. Main Outcome Measures The primary endpoints assessed over 5 years of follow-up were hemoglobin A1c (HgbA1c), low density lipoprotein (LDL) cholesterol, and blood pressure levels. Results Intention-to-treat mixed models showed that telemedicine achieved net overall reductions over five years of follow-up in the primary endpoints (HgbA1c, p = 0.001; LDL, p < 0.001; systolic and diastolic blood pressure, p = 0.024; p < 0.001). Estimated differences (95% CI) in year 5 were 0.29 (0.12, 0.46)% for HgbA1c, 3.84 (?0.08, 7.77) mg/dL for LDL cholesterol, and 4.32 (1.93, 6.72) mm Hg for systolic and 2.64 (1.53, 3.74) mm Hg for diastolic blood pressure. There were 176 deaths in the intervention group and 169 in the usual care group (hazard ratio 1.01 [0.82, 1.24]). Conclusions Telemedicine case management resulted in net improvements in HgbA1c, LDL-cholesterol and blood pressure levels over 5 years in medically underserved Medicare beneficiaries. Mortality was not different between the groups, although power was limited. Trial Registration http://clinicaltrials.gov Identifier: NCT00271739.

Investigating the association between obesity and asthma in 6- to 8-year-old Saudi children: a matched case-control study.  

PubMed

Background:Previous studies have demonstrated an association between obesity and asthma, but there remains considerable uncertainty about whether this reflects an underlying causal relationship.Aims:To investigate the association between obesity and asthma in pre-pubertal children and to investigate the roles of airway obstruction and atopy as possible causal mechanisms.Methods:We conducted an age- and sex-matched case-control study of 1,264 6- to 8-year-old schoolchildren with and without asthma recruited from 37 randomly selected schools in Madinah, Saudi Arabia. The body mass index (BMI), waist circumference and skin fold thickness of the 632 children with asthma were compared with those of the 632 control children without asthma. Associations between obesity and asthma, adjusted for other potential risk factors, were assessed separately in boys and girls using conditional logistic regression analysis. The possible mediating roles of atopy and airway obstruction were studied by investigating the impact of incorporating data on sensitisation to common aeroallergens and measurements of lung function.Results:BMI was associated with asthma in boys (odds ratio (OR)=1.14, 95% confidence interval (CI), 1.08-1.20; adjusted OR=1.11, 95% CI, 1.03-1.19) and girls (OR=1.37, 95% CI, 1.26-1.50; adjusted OR=1.38, 95% CI, 1.23-1.56). Adjusting for forced expiratory volume in 1?s had a negligible impact on these associations, but these were attenuated following adjustment for allergic sensitisation, particularly in girls (girls: OR=1.25; 95% CI, 0.96-1.60; boys: OR=1.09, 95% CI, 0.99-1.19).Conclusions:BMI is associated with asthma in pre-pubertal Saudi boys and girls; this effect does not appear to be mediated through respiratory obstruction, but in girls this may at least partially be mediated through increased risk of allergic sensitisation.

Ultrasonic implant site preparation using piezosurgery: a multicenter case series study analyzing 3,579 implants with a 1- to 3-year follow-up.  

PubMed

This multicenter case series introduces an innovative ultrasonic implant site preparation (UISP) technique as an alternative to the use of traditional rotary instruments. A total of 3,579 implants were inserted in 1,885 subjects, and the sites were prepared using a specific ultrasonic device with a 1- to 3-year follow-up. No surgical complications related to the UISP protocol were reported for any of the implant sites. Seventy-eight implants (59 maxillary, 19 mandibular) failed within 5 months of insertion, for an overall osseointegration percentage of 97.82% (97.14% maxilla, 98.75% mandible). Three maxillary implants failed after 3 years of loading, with an overall implant survival rate of 97.74% (96.99% maxilla, 98.75% mandible). PMID:24396835

Can programme theory be used as a 'translational tool' to optimise health service delivery in a national early years' initiative in Scotland: a case study  

PubMed Central

Background Theory-based evaluation (TBE) approaches are heralded as supporting formative evaluation by facilitating increased use of evaluative findings to guide programme improvement. It is essential that learning from programme implementation is better used to improve delivery and to inform other initiatives, if interventions are to be as effective as they have the potential to be. Nonetheless, few studies describe formative feedback methods, or report direct instrumental use of findings resulting from TBE. This paper uses the case of Scotland’s, National Health Service, early years’, oral health improvement initiative (Childsmile) to describe the use of TBE as a framework for providing feedback on delivery to programme staff and to assess its impact on programmatic action. Methods In-depth, semi-structured interviews and focus groups with key stakeholders explored perceived deviations between the Childsmile programme 'as delivered’ and its Programme Theory (PT). The data was thematically analysed using constant comparative methods. Findings were shared with key programme stakeholders and discussions around likely impact and necessary actions were facilitated by the authors. Documentary review and ongoing observations of programme meetings were undertaken to assess the extent to which learning was acted upon. Results On the whole, the activities documented in Childsmile’s PT were implemented as intended. This paper purposefully focuses on those activities where variation in delivery was evident. Differences resulted from the stage of roll-out reached and the flexibility given to individual NHS boards to tailor local implementation. Some adaptations were thought to have diverged from the central features of Childsmile’s PT, to the extent that there was a risk to achieving outcomes. The methods employed prompted national service improvement action, and proposals for local action by individual NHS boards to address this. Conclusions The TBE approach provided a platform, to direct attention to areas of risk within a national health initiative, and to agree which intervention components were 'core’ to its hypothesised success. The study demonstrates that PT can be used as a 'translational tool’ to facilitate instrumental use of evaluative findings to optimise implementation within a complex health improvement programme.

Engineering Case Studies  

NSDL National Science Digital Library

This website on Engineering Case Studies has been developed by Geza Kardos from the Department of Mechanical and Aerospace Engineering and Neal Holtz from the Department of Civil and Environmental Engineering at Carleton University, Ottawa, Canada, in collaboration with the RHIT Logo Rose-Hulman Institute of Technology in Terre Haute, Indiana, and the American Society for Engineering Education, and the Canadian Design Engineering Network. They have gathered together a collection of information on engineering cases which provide accounts of real engineering projects. The collection of over 250 cases is intended for use in engineering education but may also be of interest to armchair engineers. Abstracts provide an overview of the case and a search function and classification system help visitors navigate the collection. They also provide an overview on how to write engineering cases, how to use engineering cases in the classroom, and "a short treatise on the use of engineering cases." Workshop notes and background on using engineering cases to introduce more design content into the engineering curriculum may also be of interest to educators.

Outcome of combined unicompartmental knee replacement and combined or sequential anterior cruciate ligament reconstruction: a study of 52 cases with mean follow-up of five years.  

PubMed

The Oxford unicompartmental knee replacement (UKR) is an established treatment option in the management of symptomatic end-stage medial compartmental osteoarthritis (MCOA), which works well in the young and active patient. However, previous studies have shown that it is reliable only in the presence of a functionally intact anterior cruciate ligament (ACL). This review reports the outcomes, at a mean of five years and a maximum of ten years, of 52 consecutive patients with a mean age of 51 years (36 to 57) who underwent staged or simultaneous ACL reconstruction and Oxford UKR. At the last follow-up (with one patient lost to follow-up), the mean Oxford knee score was 41 (sd 6.3; 17 to 48). Two patients required conversion to TKR: one for progression of lateral compartment osteoarthritis and one for infection. Implant survival at five years was 93% (95% CI 83 to 100). All but one patient reported being satisfied with the procedure. The outcome was not significantly influenced by age, gender, femoral or tibial tunnel placement, or whether the procedure was undertaken at one- or two-stages. In summary, ACL reconstruction and Oxford UKR gives good results in patients with end-stage MCOA secondary to ACL deficiency. PMID:22933493

[Anencephaly. 10 cases seen in 3 years in Brazzaville (Congo)].  

PubMed

The authors report ten cases of anencephaly diagnosed between 1989 and 1991 in the maternity units of Brazzaville (Congo). The incidence of anencephaly was 0.12 per thousand. Although there was no geographical factors to definitely identify, there is a suspicion that the consumption of potatoes, infected by phytophotora infestans at the beginning of pregnancy may have had an effect; but this hypothesis would have to be confirmed by microbiological studies. The patients were young with a mean age of 27.5 years and were of low socio-economic levels. In this study female fetuses were often affected; which is also found in the literature but without any reasonable explanation. The means of diagnosis of anencephaly in Brazzaville have improved thanks to the recent acquisition of an ultrasound machine which made it possible to screen most of these cases. PMID:8263291

Interventional therapy in diabetic foot: risk factors, clinical events and prognosis at one year follow-up (a study of 103 cases).  

PubMed

Diabetic foot is a common complication in diabetes mellitus course, able to increase the overall morbidity/mortality risk of such a disease. The aim was to investigate the outcomes, the incidence of clinical events, the number of recurrent ulcers in patients with diabetic foot during 1 year follow-up after angioplasty (PTA) revascularization. From January 2007 to August 2009, 103 diabetic patients with diabetic foot undergoing revascularization of a lower limb by PTA were recruited. At 1 year follow-up we assessed: "major" (death, stroke, Myocardial Infaction (MI) and "minor" (Deep Vein Thrombosis (DVT), renal failure, restenosis) events incidence; recurrent ulcers incidence; the predictive elements of all these events. At 1 year follow-up, "major"/"minor" events incidence was 15% (deaths: 5, stroke: 1, MI: 9%) and 34% (renal failure: 11, DVT: 9, restenosis: 14%), respectively. Obesity, high low density level-cholesterol levels and distal arterial lesions (at posterior tibial artery in particular) were statistically significantly associated with major events (p < 0.05); only obesity resulted statistically associated with minors (p = 0.043). High levels of C-reactive protein had a statistically significant relationship with the recurrence of ulcers (p = 0.006) while distal arterial obstructions showed a trend toward significance. To improve diabetic foot mortality and morbidity rate, our study underlines the importance of a prompt diagnosis and appropriate revascularization treatment. Other studies are needed to ascertain these. PMID:24175420

Physical activity completed when young has residual bone benefits at 94 years of age: a within-subject controlled case study.  

PubMed

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

A One-year Case Study: Understanding the Rich Potential of Project-based Learning in a Virtual Reality Class for High School Students  

NASA Astrophysics Data System (ADS)

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.

Nesidioblastosis: a case study.  

PubMed

Hypoglycemia is a common problem among neonates. Transient in nature, it usually resolves with an increase in glucose intake. However, as clinicians, we must recognize that prolonged hypoglycemia may be caused by increased insulin production. Nesidioblastosis is one cause of persistent hyperinsulinism of the newborn. This case study reviews fetal physiology, neonatal presentation, and treatment. PMID:9325879

Neurodevelopment until the adjusted age of 2 years in extremely low birth weight infants after early intervention--a case-control study.  

PubMed

A total of 104 infants with birth weights of less than 1000 grams were enrolled in this prospective case-control study in order to examine the effect of occupational therapy based on sensory integration (SI) and neurodevelopmental therapy (NDT) on neurological development. The children were grouped as matched pairs on the basis of a set of developmental risks assessed at the age of 3 months. The intervention children had a weekly session of 60 minutes of occupational therapy from the corrected age of 6 months up to 12 months. All the children were examined at the corrected age of 3, 6, 9, 12, 18 and 24 months. The neurodevelopment of the cases and the controls did not differ essentially and the only significant difference was found in the social development of the children at the age of 12 months to the advantage of the intervention group. It is concluded that this amount of occupational therapy in at-risk children does not have a relevant effect on neurological development. PMID:10048099

Candida dubliniensis endophthalmitis: five cases over 15 years  

PubMed Central

Background Recent studies have shown that the recently identified organism Candida dubliniensis is less pathogenic than the more common Candida albicans. Due to its rare nature, C. dubliniensis has been previously reported as the causative organism in endophthalmitis in only three cases. We undertook a multicenter, retrospective, consecutive case series to describe the clinical features and outcomes of patients with culture-proven C. dubliniensis endophthalmitis. Medical records were reviewed for all patients with C. dubliniensis endophthalmitis on vitreous/aqueous cultures from June 1998 to June 2013 from all public hospitals throughout Queensland, Australia. Results Six eyes from five patients were identified - four males and one female aged from 21 to 55 years (mean 37 years). Four patients were intravenous drug users and four patients had hepatitis C. All five patients were treated with systemic antifungal therapy and intravitreal antifungal injections, and all required vitrectomy. Two eyes developed retinal detachment over the course of the endophthalmitis. Five eyes had visual outcomes of 20/60 or better, and one eye had a poor outcome with final visual acuity of hand movements only. There was no associated mortality, and no infected eyes required enucleation or evisceration. Conclusions C. dubliniensis endophthalmitis is a rare condition which occurs mainly in intravenous drug users and can occur in both HIV-positive and HIV-negative patients. Unlike C. albicans endophthalmitis, C. dubliniensis endophthalmitis has reasonable visual outcomes and does not appear to be associated with high mortality.

Predisposing Factors to Premature Coronary Artery Disease in Young (Age <= 45 Years) Smokers: A Single Center Retrospective Case Control Study from India  

PubMed Central

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.

Exploring impacts of multi-year, community-based care programs for orphans and vulnerable children: A case study from Kenya  

PubMed Central

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.

Firework injuries: a ten-year study.  

PubMed

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.

Interdisciplinary courses on science, engineering and society have been successfully established in two cases, at Bilkent University, Ankara, Turkey, and at the University of Hamburg, Germany. In both cases there were institutional and perceptual barriers that had to be overcome in the primarily disciplinary departments. The ingredients of success included a clear vision of interdisciplinary themes and didactics, and the exploitation of institutional opportunities. Haldun M. Ozaktas in Ankara used the dynamics of an accreditation process to establish courses on engineering and society. At the University of Hamburg the introduction of optional courses into all curricula allowed for the establishment of a seminar series on physics and society, as well as on peace education and peace building. Both of these approaches have a weakness in common: the courses can disappear once their initiators have left, unless the interdisciplinary themes are integrated into compulsory core curricula.

Case Study: The Business End of Cases  

NSDL National Science Digital Library

This article takes a retrospective look at how the folks in business schools look at the case method. The legacy of cases in business may seem short in the eyes of some but it is positively ancient when compared to the use of the case study in the sciences, which began to take hold in the 1990s. Surprisingly, in spite of its impeccable academic pedigree, there seems to be little literature on the success of the method; virtually no assessment data in business, law, or public policy teaching seems to exist.

Neonatal lupus erythematosis: a five-year case review.  

PubMed

Neonatal lupus erythematosus is an infrequent disease seen in newborns. It is caused by transplacental maternal autoantibody passage. Cutaneous involvement and congenital heart block (CHB) are the most common affections, although it may involve multiple organs like the liver, lungs, blood, nervous or digestive systems. This article present a review of the four cases diagnosed in the past five years in a Neonatal Unit, which shows the different clinical spectrum which can develop around this disease (CHB, multisystemic affection and two cutaneous cases), different autoantibodies (specially anti-SSA) with an early negativization during the first year of life and the possibility of future collagen vascular disease as occurred in one case.

What is it like to be an international student at veterinary school? Perception and performance in first year-a case study at a UK veterinary school.  

PubMed

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.

Disseminated granuloma annulare: study on eight cases.  

PubMed

Granuloma annulare (GA) is classified as localized, generalized/disseminated, subcutaneous, and perforating types. The studies show connection with diabetes mellitus, lipidic metabolic disorders, malignant diseases, thyroid disorders, infections (HBV, HCV, HIV). We performed a retrospective study between 2010-2011, regarding disseminated GA (GAD), and the relationship between GAD and other comorbidities. We clinically and histologically diagnosed eight cases of GAD. The patients were also investigated for the diagnosis of associated diseases. The treatment included topical corticosteroids, antihistamines, Calcipotriol/Betamethasone, Tacrolimus 0.03%, Pentoxifylline, Hydroxychloroquine. Therapeutic response was assessed one month and three months after hospitalization. Our patients were five women and three men, aged 46-68 years, mean age 57.25 years, with a disease history of one year and a half (between three months and four years). The lesions occurred in the upper extremities (eight cases), distal extremities (three cases), cervical area (two cases), and trunk (five cases). In seven cases, we found annular appearance and one patient had disseminated small papules eruption. Associated pathology was diabetes mellitus type II (five cases), overweight and obesity (five cases), dyslipidemia (three cases), hypothyroidism (one case), rheumatoid arthritis (one case), external ear canal basal carcinoma (one case). Although there is controversy regarding the relationship between GAD and associated diseases, it is accepted that it is significantly associated with diabetes mellitus, also found in our study in five out of eight cases. We noticed obvious improvements after local and general treatment. It is confirmed that GAD is prevalent in women, over 40-year-old. GAD is often associated with diabetes and dyslipidemia, therefore it is necessary to investigate patients in this direction. The histopathological exam is essential for an accurate confirmation of GA. PMID:23771077

[Femoro-patellar prosthesis. A retrospective study of 45 consecutive cases with a follow-up of 3-12 years].  

PubMed

Forty-five consecutive patients operated between 1986 and 1995 were evaluated to assess the long term results of patellofemoral arthroplasty. Revision had to be performed in 8 cases for the following reasons: loosening (3), lateral impingement (3), malposition (1) and persistent patella instability (1). Two groups of patients were identified based upon the preoperative assessment: 21 had primary osteoarthritis without anatomic malalignment (group C) and 24 had a history of patellofemoral instability and trochlear dysplasia demonstrated by clinical and radiological evaluation (group D). Only 43% of good results were found in group C whereas in group D, the percentage of good results was close to 83%. The most common cause of poor results in group C was the degenerative involvement of the femorotibial compartments (5 patients had to undergo total knee arthroplasty subsequently). For group D patients, femorotibial osteoarthritis was not a determinant factor as regards the outcome of patellofemoral arthroplasty. To the authors, it appears that the best indication for patellofemoral arthroplasty is femoropatellar osteoarthritis with malalignment in patients having a normal femorotibial axis even in the presence of femorotibial osteoarthritis as long as the latter does not exceed grade II.

A Study on Mental Disorders: 5-year Retrospective Study  

PubMed Central

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

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  

NASA Astrophysics Data System (ADS)

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.

Few Adverse Reactions to Metal on Metal Articulation in Total Hip Arthroplasty in a Review Study on 358 Consecutive Cases with 1 to 5 Years Follow-Up  

PubMed Central

The aim of the present study was to determine the frequency of adverse reaction to metal on metal total hip arthroplasty using a M2a-38 articulation and a Magnum articulation, (Biomet Warsaw, Indiana). All patients who had received a Metal on Metal bearing prosthesis, in two centres in Copenhagen, were asked to complete a questionnaire about groin pain. Patients with self-reported groin pain, 68/314, underwent a physical examination and had Co and Cr ion levels measured in full blood samples. Fifty patients also had a CT scan performed. The present study found one patient with bilateral arthroplasty, who had an adverse reaction on one side. In addition the study showed that females had higher values of Co and Cr, and that younger patient reported groin pain more often. The conclusion of this study is that the number of adverse reactions is low, despite the time of observation being relatively short, no high frequency of adverse reactions to this prosthesis is expected.

Two year study of cryptosporidium infection.  

PubMed Central

During a two year period 48 children admitted to hospitals in the Blackburn district were found to have cryptosporidium in stool samples. Cryptosporidium accounted for 6% of the 742 cases of childhood gastroenteritis, being as common as campylobacter. Altogether, 89% of children with cryptosporidiosis had diarrhoea, which was usually offensive and watery, and 80% vomited, the mean duration of both symptoms being six days. A substantial proportion were moderately ill with dehydration and persistent vomiting. Over half of all cases were aged 2 years or more and 37% were over 5 years. Most of the ill children were over 2 years, in contrast with other cases of gastroenteritis. Eight children were less than the 3rd centile for weight and three of these were investigated for failure to thrive. Only 6% of cases occurred in Asian children, but Asians accounted for 32% of all admissions with gastroenteritis and 59% of admissions with shigella. This unexpected ethnic difference may be due to limited contact with animals among Asians or to differences in diet.

New DDT inputs after 30 years of prohibition in Spain. A case study in agricultural soils from south-western Spain.  

PubMed

This study provides information on the current status of contamination by DDT in agricultural soils in south-western Spain. A recent use of technical DDT in at least 17% of the soils was found based on the values (<1) of the ratio R(p,)(p')/(p,)(p') = [p, p'-DDE + p, p'-DDD]/[p, p'-DDT]. According to the ratio R?,(p')/(p,)(p') = [o, p'-DDT]/[p, p'-DDT] , a dicofol type contamination was detected in about 27% of the soils. A wide range of concentrations was observed (0.08-11.1 ng/g d.w.) regardless of the type of crop soil. Enantiomeric fractions (EFs), based on the chiral analysis of o,p'-DDT residues differed from the racemic value (0.500) in most soils but they were not correlated with the study variables [DDTs], SOM, R(p,)(p')/(p,)(p') and R?,(p')/(p,)(p'). Given the health risks posed by DDT, our findings support how the environmental control of legacy pollutants such as DDT cannot be neglected. PMID:21864957

Maternal and perinatal characteristics and the risk of cow's milk allergy in infants up to 2 years of age: a case-control study nested in the Finnish population.  

PubMed

This study examined whether maternal background and perinatal factors were associated with the risk of cow's milk allergy (CMA) in infants up to 2 years of age in a nested case-control study. All children born in 1996-2004 in Finland and diagnosed with CMA by 2006 were identified (n = 16,237). For each case, one matched control was selected. Information on maternal and perinatal factors was derived from the Medical Birth Register. The associations were analyzed by conditional logistic regression. Cesarean section (adjusted odds ratio (OR) = 1.18, 95% confidence interval (CI): 1.10, 1.27) and high maternal age (> or =35 years; adjusted OR = 1.23, 95% CI: 1.11, 1.36) were associated with increased risk, whereas low maternal socioeconomic status (adjusted OR = 0.65, 95% CI: 0.59, 0.71), smoking (adjusted OR = 0.72, 95% CI: 0.67, 0.79), high number of previous deliveries (> or =5; adjusted OR = 0.71, 95% CI: 0.59, 0.86), and multiple pregnancy (adjusted OR = 0.70, 95% CI: 0.60, 0.82) were associated with decreased risk of CMA. In conclusion, maternal background and perinatal factors may play a role in the development of CMA, but further research is needed to clarify these associations and the underpinning biologic mechanisms.

Clinicopathological study of male breast carcinoma: 24 years of experience  

PubMed Central

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.

Primary orbital tumors: A review of 122 cases during a 23-year period: A histo-clinical study in material from the ENT Department of the Medical University of Silesia  

PubMed Central

Background The aim of this study was to investigate the distribution of different types of primary orbital tumors, histopathological diagnosis, and postoperative complications. Material/Methods We analyzed 122 patients (68 women and 54 men) with orbital tumors, hospitalized in the ENT Department of the Medical University of Silesia in Katowice during 1990–2013. The patients were characterized in terms of anatomic, topographical, histopathological, and clinical parameters. The role of diagnostic imagining such as CT, NMR, and fine-needle aspiration (FNB) in preoperative diagnostics is discussed. Results of FNB, cytological, and histopathological examination of the postoperative specimens were compared. Results There were 56 (46%) patients with malignant tumors, 42 (34%) with benign tumors, 19 (16%) with inflammatory tumors, and 5 patients (4%) had other tumors. In cases of malignant tumors, local recurrence up to 5 years was found in 36 (64.3%) cases. In the other 20 (35.7%) cases of malignant tumors, the patients remained under close follow-up in the outpatient clinic, without signs of local recurrence (follow-up 1–17 years). According to histopathological examination, malignant tumors were detected in 45.9% of patients and non-malignant tumor in 34.4% of patients. In 19.7% of patients, inflammatory and other types of tumors were diagnosed. Conclusions We characterized the occurrence and pathological profiles of orbital tumors. The tumor location, histopathological diagnosis, and postoperative complications give us important information for the diagnosis of tumor prior to biopsy or tumor resection and for the determination of the treatment strategy and possible complications after surgery.

River Forecasting Case Study  

NSDL National Science Digital Library

This module takes the learner through the considerations for the river forecasting decisions associated with the remnants of Hurricane Ivan on 17-19 September, 2004 for the Susquehanna River system in Pennsylvania and New York. The module assists the learner with applying the concepts covered in the foundation topics of the Basic Hydrologic Sciences course. Some of the specific topics pertinent to this case are soil conditions, the impact of QPF on runoff, runoff models, runoff processes, routed flow and stage-discharge relationships. Observations of upstream conditions and comparisons to historic crests are also examined to assist with operational flood forecast decisions. The core foundation topics are recommended as a prerequisite since this module assumes some pre-existing knowledge of hydrologic principles.

Intravesical stone formation several years after hysterectomy: a case report  

PubMed Central

Introduction Most bladder stones develop in patients with bladder outlet obstruction. Intravesical stone formation after surgery outside the urinary bladder is rare. Case presentation A 54-year-old Taiwanese woman with lower urinary tract symptoms following a hysterectomy 14 years ago presented to our hospital. The intravesical calculus had developed from non-absorbable sutures and hung on the dome of the urinary bladder. The stone and residuum of the suture were retrieved by performing an endoscopic procedure. Conclusions The presence of an intravesical stone should be suspected in patients with a history of hysterectomy who have symptoms in the lower urinary tract. A hanging stone on the dome of the urinary bladder implies that suture materials migrate into the urinary bladder. The complication can be prevented by the routine use of absorbable material and double-checking with cystoscopy.

DBMS conversion case study  

SciTech Connect

The Integrated Procurement System (IPS) is a very large data base application that supports purchasing, accounts payable and cost accounting for materials and services at Sandia National Laboratories. The system was the first data base application installed as a production system and has been around since the early 1970s. The size of the network data base is approximately 130 million characters and there are approximately 20 separate production jobs that run against it to perform various functions. In all, there are about 80 programs with a total of around 120,000 lines of COBOL source code. Several years ago, a redevelopment effort was launched to design and program a new Integrated Procurement System which would incorporate several features that were not available in the old version, including the capability to account for line item details on purchase orders and to perform our receiving function in an automated fashion rather than manually. It was also a goal to have all data input via screen programs, i.e., terminal input rather than keypunch and batched. The development of this conversion is described.

Using Case Studies to Teach Science  

NSDL National Science Digital Library

Storytelling as a formal educational device arguably entered the didactic scene about 100 years ago with case study teaching at Harvard (Herreid 1994). There in the law and business schools, instructors and students analyzed realistic stories as exemplars of good and bad practice. Today, however, storytelling does not have to be limited to the traditional discussion formula advocated in these schools. This chapter describes various types of case study methods, reviews their virtues and weaknesses, and discusses the impact of case-based instruction in science education.

Thirty years of blackouts: a case report of swallow syncope  

PubMed Central

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.

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.

Factors influencing renal survival were investigated using Cox regression analysis. Results Renal survival at 5, 10, 20 and 30 years was 87, 78, 59 and 50%, respectively. Female survival after 30 years was significantly better than male survival (70 vs. 40%, p = 0.049). Multivariate analysis, adjusted for age, estimated glomerular filtration rate (GFR) and nephrotic syndrome (NS) was performed for each sex individually. An increase in GFR was associated with a hazard risk (HR) of 0.98 (p = 0.02) in women and 0.99 (p = 0.006) in men. Older age was associated with a HR of 1.04 (p = 0.02) in women and 1.03 (p = 0.004) in men. NS had a poorer prognosis in men (HR 2.53, p = 0.01), but not in women (HR 0.54, p = 0.38). Conclusion Increasing age and decreasing GFR were adversely associated with renal death. Renal prognosis was better for women after 30 years, and NS resulted in a poorer prognosis in men. This suggests that disease course and prognosis are different between men and women.

Case Study: Introducing Students to Cases  

NSDL National Science Digital Library

Strategically introducing students to a controversial science case--before they read it, watch it, or listen to it--motivates them to learn from it and paves the way for successful discussion and debate. A strategic introduction also provides an opportunity for the instructor to demonstrate scientific reasoning and share guidelines for the discussion and debate. In this article, the authors describe and illustrate how instructors should introduce students to a controversial case and prepare them for debating issues related to it.

Use of personalized decision analysis in decision making for Palliative vs. surgical management of the oldest-old patients with localized skin cancer in a culturally sensitive environment: a case study of a 96-year-old male Taiwanese patient.  

PubMed

Clinical management of older cancer patients is challenging, especially for those in the oldest-old age group. In the Chinese culture, the preference toward noninvasive care for patients in this age group may create a difficult situation for clinicians when the cancer is potentially curable. Palliative care may not always be the obvious choice, especially if patients suffer from quality-of-life impairment because of symptoms related to progression of the untreated cancer. Balancing between higher rates of toxicities and potential gains in quality of life from anticancer therapies among the oldest old presents a real challenge in clinical practice. Decision analysis is an analytical tool that has a long history of successful application in clinical decision making. In this case study of a 96-year-old male with localized skin cancer, we demonstrate that personalized decision analysis can be a helpful tool to assist decision making in the clinical management of cancer patients in the oldest-old age group, especially in situations in which the evidence-based literature provides little guidance. This was achieved by providing information to help the key decision makers to better understand the risk-benefit trade offs and make an informed decision. We found that the option of surgical management was associated with higher expected quality-adjusted life years (0.894) than best supportive care (0.853). Based on this finding and various scenarios explored in sensitivity analyses, the family members recommended surgery for the patient. The patient recovered well from surgery and there is no evidence of recurrence to date. PMID:22917709

Intracranial Subdural Empyema: A 10-Year Case Series  

PubMed Central

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.

[A twelve-years-old girl with multiloculated gynandroblastoma CD99 negative: case report].  

PubMed

The ginandroblastoma is an extremely rare ovarian tumor which shows components of granulosa cells and Sertoli/Leydig cells. We describe a case of a twelve-years-old girl who presented abnormal uterine bleeding and progressively growing intraabdominal mass associated with menorrhagia, CA-125 60.4 UI/mL and extension studies reporting cystic mass in the left ovary. She underwent oophorectomy. Pathological study shows a multilocular tumor filled with serous material. Many Call-Exner bodies were observed in the histopathological analysis, 45% of Sertoli/Leydig cells. Immunohistochemistry was reactive for inhibin, calretinin and pCK while AE1/AE3 and CD99 markers were negative. This is the first case report about a multiloculated gynandroblastoma, negative for CD99 in a 12-years-old girl. Thus, the study of this clinical case represents a systematic approach for tumors of the sex cord cells. PMID:24955913

Mastoiditis in adults: a 19-year retrospective study.  

PubMed

The objective of our study was to review retrospectively the clinical, radiological and therapeutic findings in 62 adults with acute mastoiditis treated at the ENT Department of Ferrara from 1992 to 2010. 62 adult cases fulfilled the following inclusion criteria: otoscopical evidence of co-existent or recent otitis media; postauricular swelling, erythema or tenderness; protrusion of the auricle; fever and/or significant radiological findings of mastoiditis. Conservative treatment comprehended antibiotic ± ventilation tube. Surgical procedures comprehended mastoidectomy or mastoido-tympanoplasty. The incidence of adult's mastoiditis in our district (0.99 cases/year/100.000 inhabitants) has maintained quite stable during the considered 19-year period. The typical clinical presentation was observed in 48 % of cases. Complications were meningitis (15 cases), meningo-encephalitis (1), meningitis associated with lateral sinus thrombosis (1), facial nerve paralysis (11), and labyrinthitis (8). In all cases except one, the facial palsy recovered completely and no mortality was observed due to these complications. Complete cure was obtained with conservative treatment in 69 % of uncomplicated cases and in 24 % of patients with intracranial complications. Mastoiditis in adults may present as the acute classical form, as well as latent forms which often have prolonged and insidious development followed by a rapid clinical deterioration. Clinical features are frequently atypical, while incidence of meningitis and other complications is still high particularly in the most elderly. Thus, great care is required from clinicians to make an early diagnosis in order to promote adequate treatment. PMID:23589156

Fatal poisonings in Oslo: a one-year observational study  

PubMed Central

Background Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Methods Fatal and non-fatal acute poisonings in subjects aged ?16 years in Oslo (428 198 inhabitants) were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic), and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. Results In Oslo, during the one-year period studied, 103 subjects aged ?16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years). In 92 cases (89%), death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases), followed by ethanol (9%), tricyclic anti-depressants (TCAs) (4%), benzodiazepines (4%), and zopiclone (4%). Seventy-one (69%) were evaluated as accidental deaths and 32 (31%) as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04). Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91), 14% (95% C.I., 0.04-0.33), and 10% (95% C.I., 0.02-0.27), respectively. Conclusions Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental deaths. Although case fatality rates were highest for methanol, TCAs, and antihistamines, most deaths were caused by opiates or opioids.

Benign breast lesions in an African population: A 25-year histopathological review of 1864 cases  

PubMed Central

Objective: The objective of this study was to delineate the prevalence and characterize the histologic pattern of benign breast diseases (BBDs) in the University of Benin Teaching Hospital, Benin City, Nigeria. Materials and Methods: A 25-year-old (1985-2009) retrospective study of all patients presenting with BBD. Results: During the 25-year-old study period, 1864 cases of BBD constituting 72.4% of all breast lesions were seen. The female to male ratio was 28.6:1. An increasing incidence of BBDs was observed. The overall mean age for BBD was 27.5 years, SD±11.3 with an age range of 9-84 years and a peak age occurrence in the third decade. The single most common lesion was fibroadenoma accounting for 43.1% of cases, followed by fibrocystic change (23.8%) with mean ages of 22.3 years and 30.2 years, respectively. Both lesions had a peak occurrence in the third decade. Other major lesions encountered were sclerosing adenosis (7.3%), atypical ductal hyperplasia (3.6%), and blunt duct adenosis (2.3%). Gynecomastia (2.1%) was the predominant lesion in males. Inflammatory lesions constituted 8.1% of cases while stromal and skin lesions accounted for 1.1% and 0.9% of cases respectively. Conclusion: BBDs constituted 70% of breast lumps and were mostly fibroadenoma and fibrocystic change. BBDs occurred predominantly in young females with a peak in the third decade. Though premalignant lesions of atypical hyperplasia were less common, biopsy of all BBDs should be done to exclude these lesions and routine mammographic screening of at risk individuals instituted to increase their detection.

Case study in Reunion Island  

NASA Astrophysics Data System (ADS)

This paper presents the status of a case study that is being carried in Reunion Island, France, to investigate the opportunity to use a point-to-point wireless power transmission link to deliver electricity to a small isolated village called Grand-Bassin. The different steps followed since this case study was first started are briefly reminded. The last stage consisting in the development of an indoor industrial prototype is presented. Perspectives are given towards the emergence of a semi-private organization whose first role would be to evaluate the viability of the concept of using WPT as a way to extend the conventional electricity grid in order to provide energy to remote places not only in Reunion Island, but in many places around the world. This organization would also have as a role, to head the industrial engineering and development of point-to-point WPT prototype equipment.

Primary Cutaneous Melanoma: An 18-Year Study  

PubMed Central

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.

Giant adrenal cyst: case study  

PubMed Central

One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61Z–year old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24–h 17–ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

Resurfacing hip replacement and cemented total hip replacement have equivalent outcome at one year in a disease matched population: a case-control study of patient reported outcome measures.  

PubMed

Resurfacing hip replacement has demonstrated good survival and outcomes for cohorts of younger male patients, but few controlled studies exist. In this study we compared patient reported outcome measures and satisfaction scores at one year following resurfacing hip replacement in 69 male patients with two control groups of equal numbers undergoing cemented total hip replacement: aged-matched patients and disease matched patients. At one year we found no difference in improvement in patient reported outcome measures between patients undergoing resurfacing hip replacement and disease matched patients, whereas patients undergoing resurfacing hip replacement had a statistically significant improvement in Oxford Hip Score compared to the age-matched controls (p<0.047) although this was below the minimally clinically detectable difference. Resurfacing hip replacement and total ?hip replacement both confer increase in patient reported outcome scores and high patient satisfaction at one year. The results of this study will allow better counselling of patients and help inform ?treatment decisions. PMID:23813167

A FIVE-YEAR STUDY OF PREMATURITY  

PubMed Central

To get a comprehensive picture of prematurity and neonatal death or survival, all factors on the maternal and fetal records that might be pertinent were recorded. This information, having to do with factors such as age, gravida of the mother, blood group incompatibility, period of gestation, weight at birth, type of delivery, medication and anesthesia administered to the mother, is presented in tabular form. In the study of perinatal mortality it was noted that failure to establish normal pulmonary ventilation is the most common cause of death in the neonatal period. Maternal history of relative infertility, that is, previous abortions, stillbirths and premature deliveries, was the most impressive finding in the stillborn series. In the follow-up study of premature infants who survived the neonatal period, 8.5 per cent were found to be severely handicapped. In four cases the handicap was due to congenital anomalies, in two others probably to infection, leaving 12 with complications possibly ascribable to prematurity. Six of these had retrolental fibroplasia as a major handicap. In seven, mental retardation was the presenting problem. Most of the handicapped children had multiple handicaps, which included spasticity, delayed motor development, strabismus, etc. The incidence of the necessity for corrective measures for feet and legs appeared relatively high. In general, survivors compared favorably with the rest of the childhood population. Complications and twinning were associated inordinately often.

Pancreatic schwannoma: Case report and an updated 30-year review of the literature yielding 47 cases  

PubMed Central

Pancreatic schwannomas are rare neoplasms. Authors briefly describe a 64-year-old female patient with cystic pancreatic schwannoma mimicking other cystic tumors and review the literature. Databases for PubMed were searched for English-language articles from 1980 to 2010 using a list of keywords, as well as references from review articles. Only 41 articles, including 47 cases, have been reported in the English literature. The mean age was 55.7 years (range 20-87 years), with 45% of patients being male. Mean tumor size was 6.2 cm (range 1-20 cm). Tumor location was the head (40%), head and body (6%), body (21%), body and tail (15%), tail (4%), and uncinate process (13%). Thirty-four percent of patients exhibited solid tumors and 60% of patients exhibited cystic tumors. Treatment included pancreaticoduodenectomy (32%), distal pancreatectomy (21%), enucleation (15%), unresectable (4%), refused operation (2%) and the detail of resection was not specified in 26% of patients. No patients died of disease with a mean follow-up of 15.7 mo (range 3-65 mo), although 5 (11%) patients had a malignancy. The tumor size was significantly related to malignant tumor (13.8 ± 6.2 cm for malignancy vs 5.5 ± 4.4 cm for benign, P = 0.001) and cystic formation (7.9 ± 5.9 cm for cystic tumor vs 3.9 ± 2.4 cm for solid tumor, P = 0.005). The preoperative diagnosis of pancreatic schwannoma remains difficult. Cystic pancreatic schwannomas should be considered in the differential diagnosis of cystic neoplasms and pseudocysts. In our case, intraoperative frozen section confirmed the diagnosis of a schwannoma. Simple enucleation may be adequate, if this is possible.

[Case of pineocytoma causing repetitive subarachnoid hemorrhage for 43 years].  

PubMed

A 61-year-old woman had suffered from severe headache and nausea over 20 times during the last 43 years. An subarachnoid hemorrhage (SAH) was detected by spinal puncture in some other hospitals, but the source of hemorrhage remained unknown in spite of repeated angiography. At the age of 61, she was diagnosed as having normal pressure hydrocephalus, and received a ventriculo-peritoneal shunt. She suffered from sudden headache 12 days after surgery. A CT scan showed a SAH and enlargement of the pineal mass. The tumor was totally removed via the occipital interhemispheric transtentorial approach and was diagnosed histologically as a pineocytoma. She has been free from SAH for three years since removal of the tumor. Pineal apoplexy should be considered as a cause of SAH. PMID:18341015

French brain tumor database: 5-year histological results on 25 756 cases.  

PubMed

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

Suicide in India: a four year retrospective study.  

PubMed

Suicide is one of the ten leading causes of death in the world, accounting for more than a million deaths annually. The purpose of the study was to identify the risk groups. In the four-year period from January 2000 to December 2003, 588 suicide victims were autopsied. Information was obtained by interviewing the acquaintances of the victim, perusal of hospital records and the autopsy findings. All the cases were analyzed as to sex, age, and methods of suicide, seasonal variation, diurnal variation and other sociological aspects. The present study depicts a suicidal rate of 11.76 per 100,000 population. Males and females were almost equally the sufferers. The largest number of victims were found in the age group of 21-30 years. Hanging and poisoning constituted the two major modes of suicides (63%). Majority of the victims were mentally sound, married and were from rural background. Victims were mostly drawn from low socioeconomic status (48%). Less educated or illiterates were usually the victims. Suicidal note was detected in 5% of cases. Suicidal tendency and alcohol intake could not be encountered in most of the cases. Indoor incidence was almost double of the outdoor incidence, mostly seen in rainy season (43%) and occurred almost equally during day and night. Financial burden (37%) and marital disharmony (35%) were the principal reasons for the suicide. PMID:16914358

Why breed every other year? The case of albatrosses.  

PubMed Central

Albatrosses exhibit extremely low reproductive rates, each pair brooding only one egg and subsequent chick at a time. Furthermore, in several of the species, the majority of successful pairs breed only once every second year (termed 'biennial' breeding). Thus, on average, these latter species have an annual fecundity of about half an offspring per year, while other albatrosses produce an egg and chick every year. Using our 40-year bank of demographic data, we compared 12 species of albatrosses according to these two breeding strategies to examine potential causes of biennial breeding. Biennial breeding could be due to physiological constraints, larger animals breeding more slowly, or ecological constraints, more distant pelagic feeding trips being energetically costly, or both. We tested these hypotheses by looking for predicted associations between the duration of the rearing period, the distance to the oceanic feeding zone and breeding frequency. We also looked for associations of these variables with other life-history traits. Body size had a strong influence on the duration of the rearing period, but not on the distance that birds travelled to the feeding zone. Both the duration of the rearing period and distance to the feeding zone appeared to have direct influences on breeding frequency, as revealed by a path analysis, and thus both hypotheses to explain biennial breeding were supported. Finally, breeding frequency exhibited a strong trade-off with adult survival and age at maturity, indicating that slower breeders live through more breeding seasons, perhaps mitigating their lower annual reproductive output.

A historic case of visual agnosia revisited after 40 years.  

PubMed

In one of the seminal works on visual agnosia, Adler (1944, 1950) presented the case of a 22-yr-old woman who sustained carbon monoxide cerebral toxicity in the Cocoanut Grove nightclub diaster of 1942. We located this patient 40 yrs after injury and performed a detailed reevaluation. The patient demonstrated persistent deficits in visual recognition, characterized most prominently by defective recognition of elemental shape and form, associated with alexia, prosopagnosia, visuospatial disorientation and impaired visual imagery. Visual acuity, colour recognition, writing ability and verbal intelligence were relatively preserved. Isolated bilateral occipital injury was demonstrated by CT and MRI scanning. On comparison with previously reported cases, our results support the hypothesis that carbon monoxide toxicity can induce a visual agnosia of the apperceptive type with well defined characteristics, seldom seen with other types of cerebral injury. Prognosis for long-term recovery is poor. PMID:2043949

Physiologic amputation: a case study.  

PubMed

Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation. PMID:24534085

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%).

Ten years of tuberculosis intervention in Greenland - has it prevented cases of childhood tuberculosis?  

PubMed Central

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.

Rapunzel Syndrome Case Report: A 13-year-old Girl.  

PubMed

Bezoars are masses, which are commonly encountered in patients after stomach surgery or in those with psychiatric problems, formed by the accumulation of intraluminal nondigestible substances that can lead to obstruction of the stomach and the small intestine. The anatomical changes in the gastrointestinal tract are known to cause bezoar formation. In the absence of an anatomical change, psychiatric disorders such as trichotillomania may lead to the formation of trichobezoars in the stomach. The so-called Rapunzel syndrome is the extension of the bezoars down to the duodenum and the jejunum, which is a rare condition. In this paper, a 13-year-old patient with trichotillomania is reported, who was admitted to our clinic with nausea, vomiting, and fatigue complaints, in whom a giant trichobezoar was identified, which completely filled the stomach and duodenum, without causing obstruction.

[Ergotamine poisoning: a case study].  

PubMed

Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

Life satisfaction in young adults 10 or more years after hematopoietic stem cell transplantation for childhood malignant and nonmalignant diseases does not show significant impairment compared with healthy controls: a case-matched study.  

PubMed

Patients undergoing hematopoietic stem cell transplantation (HSCT) may experience physical and psychological deterioration that impairs their life satisfaction (LS). This study focused on LS in long-term survivors at 10 or more years after HSCT. Fifty-five patients (39 males, median age 25 years) undergoing allogeneic HSCT for childhood malignant (n = 52) or nonmalignant diseases (n = 3) were enrolled. A control group of 98 young adults (59 males, median age 24 years) was considered. A questionnaire with a modified Satisfaction Life Domain Scale was administered. We assessed such domains as education, employment, leisure time, social relationships, and perception of physical status with a 30-item questionnaire. To investigate the association between the domains and the probability of diminished LS, we performed a logistical procedure using the maximum likelihood method. Predictive factors of LS were adjusted for sociodemographic variables. In the multivariate analysis, the participant's level of LS was not significantly correlated with sociodemographic factors or with HSCT status. The same analysis showed a slight trend in favor of the control group (P = .06) for body perception. Our data suggest that the patients who undergo HSCT in childhood have no significant difference in long-term LS compared with healthy controls. PMID:22766222

Hemoglobin H disease in Muscat, Oman - A 5 year study  

PubMed Central

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.

Investigation on 2331 Cases of Pulled Elbow Over the Last 10 Years  

PubMed Central

Pulled elbow is a common upper extremity injury in children. We present a retrospective study of 2331 pulled elbow cases examined in our hospital over the last ten years. All pediatric patients with a diagnosis of pulled elbow from January 2002 to December 2011 were retrospectively reviewed according to sex, age, affected arm, recurrence rate, mechanism of injury and treatment outcomes. There is no significant sex difference. The frequency of injury peaked for both boys and girls at 6 months and 2 years of age. The left arm was more affected than the right. The recurrence rate was 14%. In about 50% of cases, the cause of injury was forcible traction to the forearm. Almost all of the splinted patients, caused by severe pain or lack of mobility of the affected limb following reduction, recovered within 2 weeks, but 2 were later diagnosed with a fracture. For infants less than 1 year old, injury can often occur when rolling over. For children 1 year old or older the left arm is more commonly affected, and the frequency of injuries to the left arm increases with age, possibly because the left hand is commonly held by the guardian’s dominant right hand and faster development of muscle strength in the child’s dominant right arm works toward preventing injury to that arm with age.

A 12-year study of menarcheal age.  

PubMed Central

Data on menarcheal age were collected on girls admitted to the University College of Swansea over a 12-year period. It appears that the downward trend in menarcheal age ceased in girls born about 1946 (the 1965 student intake) and that an upward swing may have since occurred. This change in the secular trend is not due to the association of menarcheal age with family size or of position in sibship, or to changes in the regional composition of the student intake. The well established effect of physique remains, but there is no effect of socio-economic status as assessed by the Registrar-General's classification of the father's occupation.

Molecular genetics study of deafness in Brazil: 8-year experience.  

PubMed

Hereditary hearing loss is a complex disorder that involves a large number of genes. In developed countries, 1 in 1,000 children is born with deafness severe enough to require special education services, and about 60% of the cases of isolated deafness have a genetic origin. Although more than 100 genes for hearing loss are known currently, only a few are routinely tested in the clinical practice. In this study, we present our findings from the molecular diagnostic screening of the GJB2 and GJB3 genes, del(GJB6-D13S1,830) and del(GJB6-D13S1,854) deletions in the GJB6 gene, Q829X mutation in the otoferlin gene (OTOF) and, the A1,555G and A7,445G mutations in the mitochondrial genome over an 8-year period. Mutations analysis in the previously mentioned genes and mutations was performed on 645 unrelated Brazilian patients with hearing loss who fell into two different testing groups. Different mutations in the GJB2 gene were responsible for most of cases studied, but deletions in the GJB6 gene as well as mitochondrial mutations were also found. While most cases of hearing loss in this country are due to environmental factors, the genetic etiology of deafness will increasingly be determined as more genetic tests become available.

Severe noise-induced deafness--a 10-year review of cases.  

PubMed

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

Congenital lobar emphysema: 30-year case series in two university hospitals*  

PubMed Central

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.

Quality of case reports of adverse drug reactions with psychotropic drugs: a 25-year review.  

PubMed

Case reports of adverse reactions with psychotropic drugs can be useful in raising hypotheses, to be tested with more rigorous study designs. However such reports have significant methodological drawbacks, making it hard to determine causality. We undertook a systematic assessment of the quality of case reports and small case series published within Human Psychopharmacology over 25 years. For reports of adverse drug reactions, modified Bradford Hill criteria for causality (for consistency, strength, specificity, temporal relationship and plausibility) were used to ascertain the quality of the account. Reports which had been cited at least 10 times by December 2010 were examined in detail, to assess their overall contribution in extending understanding and influencing clinical practice. Of 40 reports of adverse drug reactions, only seven were sufficiently robust for confidence in probable or possible causality. Nine reports had been cited more than 10 times: the five most frequently cited reports of adverse drug reactions described movement disorders, suicidal thoughts and discontinuation symptoms with SSRIs: clinical relevance was high, but their quality was not markedly greater than less frequently cited reports. Nearly all reports of adverse drug reactions, published in a single journal over 25 years, were insufficiently robust to demonstrate probable causality. Reports that are cited frequently become influential because of their potential clinical relevance, rather than due to their methodological quality. PMID:23754771

Thirty-year follow-up of a TMD case treated based on the neuromuscular concept.  

PubMed

Aim: Occlusal therapy is employed to alleviate the symptoms of a temporomandibular disorder (TMD) at times. However, the long-term effect of occlusal therapy in the masticatory system is not well understood. This case study aims to present a 30-year follow-up of a TMD case. Methodology: The patient developed TMD with intermittent closed lock of the left temporomandibular joint (TMJ). Chief complaints included trismus, pain, and noise of the left TMJ during function. The patient's occlusal disharmony was assessed with use of electronic instruments and corrected based on the neuromuscular concept. A minimum-invasive and reversible approach using adhesive occlusal restorations was used. Results: The jaw movement and masticatory muscle activity assessed at the 7- and 23-year follow-ups revealed that the established occlusion was well adapted, and re-established the patient's functional occlusion system. The patient has been free from TMD symptoms with the corrected occlusion for 30 years. Conclusions: Occlusal reconstruction based on the neuromuscular concept can be stably integrated into the patient's functional occlusion system. PMID:25000166

Toxicology Testing in Fatally Injured Workers: A Review of Five Years of Iowa FACE Cases  

PubMed Central

Toxicology testing of fatally injured workers is not routinely conducted. We completed a case-series study of 2005–2009 occupational fatalities captured by Iowa’s Fatality Assessment and Control Evaluation (FACE) Program. The goals of our research were to: (1) measure the proportion of FACE cases that undergo toxicology testing, and describe the factors associated with being tested, and (2) measure the rate of positive toxicology tests, the substances identified and the demographics and occupations of victims who tested positive. Case documents and toxicology laboratory reports were reviewed. There were 427 occupational deaths from 2005 to 2009. Only 69% underwent toxicology testing. Younger workers had greater odds of being tested. Among occupational groups, workers in farming, fishing and forestry had half the odds of being tested compared to other occupational groups. Of the 280 cases with toxicology tests completed, 22% (n = 61) were found to have positive toxicology testing. Commonly identified drug classes included cannabinoids and alcohols. Based on the small number of positive tests, older victims (65+ years) tested positive more frequently than younger workers. Management, business, science, arts, service and sales/office workers had proportionately more positive toxicology tests (almost 30%) compared with other workers (18–22%). These results identify an area in need of further research efforts and a potential target for injury prevention strategies.

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

Uterine Leiomyosarcoma : 14-year Two-center Experience of 31 Cases  

PubMed Central

Purpose The aim of this study was to evaluate the clinicopathological characteristics of uterine leiomyosarcoma (LMS) and possible prognostic factors. Materials and Methods This study included 31 patients with histologically proven LMS at Samsung Medical Center and Ajou University Hospital between 1994 and 2007. The medical records and available histological slides were reviewed retrospectively. Results The median age was 46 years (range, 32~63). The most common symptom was vaginal bleeding (11 patients, 35.5%). There were 23 patients with stage I, one patient with stage III, seven patients with stage IV disease. The median follow up time was 29 months (range, 1~94). The most common recurrence site was lung (5 case), followed by pelvis and upper abdomen (2 case). Nine patients died of disease with a 5-year overall survival rate of 63%. Early tumor stage and mitotic count were the prognostic factor in univariate analysis (p<0.0001 and p=0.0031, respectively), but early tumor stage only was associated with prognosis in multivariate analysis (p=0.010 vs p=0.143). Adjuvant treatment for early stage disease did not decrease the recurrence rate (p=0.1075), but high mitotic count (15>10HPF) had a trend for disease recurrence in early stage LMS (p=0.0859). Conclusion Mitotic count less than 15/HPF in early stage may be related with longer progression-free interval, but we could not reach the conclusion that adjuvant therapy in early stage LMS be effective.

Achievement of three year remission in a case of aggressive glioblastoma using a multidisciplinary treatment strategy: A case report  

PubMed Central

Glioblastoma (GB) is the most common type of malignant tumor of the central nervous system and, despite extensive research, its prognosis is poor. Although recent advances have been made in the treatment of GB with aggressive resection combined with radiochemotherapy, more than three-quarters of GB patients succumb to the disease within two years. The current study presents a highly aggressive case of small cell GB as diagnosed by histological features and immunohistochemistry for vimentin, glial fibrillary acidic protein, oligodendrocyte lineage transcription factor 2, isocitrate dehydrogenase 1-R132H and p53. The patient was treated using a multidisciplinary treatment strategy, which included temozolomide, CyberKnife radiotherapy and autologous formalin-fixed tumor vaccination. In addition, the patient developed radiation necrosis, which was treated with bevacizumab. In conclusion, three years following the initial diagnosis, the patient continues to experience a successful clinical course, and the observations of the current study demonstrate that a multidisciplinary treatment strategy may be effective for the treatment of aggressive GB.

[An epidemiological study of clustering of sarcoidosis cases].  

PubMed

The clustering of sarcoidosis cases has been reported only in two places in the world; Vasterbotten Province, northern Sweden and Furano, central Hokkaido. In Furano basin, 45 sarcoidosis cases were histologically diagnosed during a 21 year period, 1972 through 1992. The incidence has recently re-increased, though it went down after the first notice of the clustering which promoted environmental improvement such as water supply and road pavement. 1) Of the 45 cases, 12 were males and 33 were females, with the preponderance of female cases over 40 years of age numbering 33. 2) Familial sarcoidosis was found in 4 families. 3) Furano cases tended to have persistent involvements of sarcoidosis with unfavourable prognosis. 4) Case-control studies did not elucidate any significant factors examined. 5) HLA examinations revealed a high rate in DR-9 and DRw53 and a low rate in DRw52.

Unraveling phonological conspiracies: A case study.  

PubMed

Abstract 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

Pathologic findings of Whipple pancreaticoduodenectomy: a 5-year review on 51 cases at Taleghani general hospital  

PubMed Central

Aim The aim of this study was to comprehensively analyze histopathologic parameters of Whipple pancreaticoduodenectomy specimens at Taleghani general hospital pathology department. Background The Whipple procedure is performed for variety of tumors involving the head of the pancreas, ampulla of Vater, common bile duct, or duodenum. Patients and methods Records of all cases of Whipple pancreaticoduodenectomy between 2007 and 2011were retrospectively reviewed and pathological details of diagnosis and staging were extracted. Results A total of 51 patients underwent Whipple procedure during a 5-year period, including 37 males and 14 females. The average age was 57 years (18-82 years). The most frequent presenting symptoms were jaundice and weight loss. Forty-four patients (86.3%) had malignant and 7 (13.7%) had benign lesions. Among malignant lesions, 27 (61.4%) were ampullary carcinomas, 12 (27.3%) were pancreatic carcinomas and 5 (11.4%) were cholangiocarcinomas. The pathological stage of most of the tumors was T3 (50%); followed by T2 (29.5%), and T1 (15.9%); only 4.5% were T4. Mean tumor size was 2.8 cm (0.2-7 cm). Duodenal and common bile duct margins were tumor-free in most cases (95.5 %). The pancreatic margin was free in 81.8% of patients; this margin had not been evaluated in 5 patients. Nearly 38.6% of all tumors showed vascular invasion while 68.2% showed perineural invasion. The average number of dissected lymph nodes was 4 (range 1-15); although in 25% of specimens, no lymph nodes had been found. Twelve specimens (35.3%) had lymph node metastases. Conclusion The present study demonstrates that most of our patients are diagnosed with malignancy, at advanced stage, and further research is needed to develop practical methods for earlier diagnosis. The fact that 25% of specimens had no lymph nodes needs more consideration.

PubMed Central

To evaluate the role of pregnancy in the pathogenesis and clinical course of Hodgkin's disease (HD), we studied a series of 192 female patients aged 17-50 years at the time of diagnosis, and 496 healthy controls matched by residence and year of birth. Cases showed a marginally significant excess for the father having a high level of education, and more families were classified as white-collar workers than as industrial workers. No significant differences between cases and controls were found in other parameters describing the family and living conditions in childhood. Before the age when cases were diagnosed, 35.4% of cases and 34.7% of their controls were nulliparous. Among the cases, the mean age at first delivery was 22.4 years, with a total of 201 children (average: 1.05 per case) born before diagnosis; for the controls, the corresponding figures were 22.2 years and 573 children (average: 1.15). Within the first 6 months after the last delivery, HD was diagnosed in 12 of 124 parous cases (9.7%); for controls, the corresponding number is 18 out of 324 (5.6%). A marginally significant negative trend (P = 0.07) in odds ratios is seen with increasing duration of this interval. We conclude that our study could not confirm previous reports of a protective effect of pregnancy for the risk of HD. On the other hand, marked physiological changes in the period of puerperium may accelerate the expression of HD.

Bifid condyle: review of the literature of the last 10 years and report of two cases.  

PubMed

Bifid mandibular condyle is a rare anomaly; there are several theories about its etiology, and it has been studied in both prehistoric and historic skulls, as well as in living human beings. It is a frequent, although unexpected, finding in asymptomatic individuals during radiological treatment. Presented here is a review of the literature over the past 10 years and two new cases of unilateral bifid condyle. Computerized tomography is usually considered the test of choice for establishing the differential diagnosis, although in certain cases, its use seems questionable. The distinction between bifid condyle and condylar notch or cleft has been described in the literature, it is proposed a criteria for defining bifid condyle depending on the level of the two heads. It is suggested that further testing such as MRI or CT be carried out only in cases where the therapeutic approach involves an active treatment. It is proposed that bifid condyle is described as that which presents two condylar heads emerging from the neck of the condyle or further down. PMID:20491236

Osteoporosis resulting from acute lymphoblastic leukemia in a 7-year-old boy: a case report  

PubMed Central

Introduction Osteoporosis in children is rare and usually secondary to an underlying disease process whose diagnosis may be difficult to detect. Etiological factors responsible for osteoporosis secondary to chronic illness include immobility, pubertal delay and other hormonal disturbances. Rarely, it can be a manifestation of acute lymphoblastic leukemia. Most of the reported bone fracture incidences associated with acute lymphoblastic leukemia occur during the course of the chemotherapy, not at the point of the first symptoms of leukemic disease, as happened with the case presented here. Case presentation A 7-year-old Asian Balinese boy presented with back pain. His anteroposterior pelvic radiograph showed osteoporotic bone. A bone age study revealed growth failure of his metacarpals, phalanges and sesamoid. His total bone mass density was 97% age-match. However, a peripheral blood smear showed normochromic anemia with thrombocytopenia. Immunophenotyping of his peripheral blood revealed no dominant markers, but a bone marrow aspiration confirmed a diagnosis of acute lymphoblastic leukemia. Conclusions Osteoporosis was the only manifestation of the child’s underlying acute lymphoblastic leukemia. Leukemia was diagnosed when his bone marrow was found to contain more than 25% blasts. Because of leucopenia, the immunophenotype failed to reveal a dominant marker in this case, thus we were unable to classify the acute lymphoblastic leukemia.

Ethical issues in case study publication: "making our case(s)" ethically.  

PubMed

As chaplains develop richly detailed case studies for publication, ethical questions about case study construction and publication are emerging. Concerns about seeking patients' permission to publish material about them suggest additional questions and raise broad confidentiality and privacy issues. Confidentiality-related practices in health care and psychotherapy provide the most extensive guidance for chaplains, but healthcare chaplaincy has roots in religious and professional traditions with distinct notions of confidentiality that deserve consideration. Single case studies do not appear to be "research" requiring informed consent, yet their publication exposes patients to some risk of harm. Obtaining the patient's/"case study subject's" permission to publish, disguising non-essential information, and allowing the patient to review the case study can mitigate the risks. Striking a balance between protecting patients and providing sufficient detail to make case studies useful is a central ethical challenge of case study publication. PMID:21534067

Invasive pulmonary aspergillosis 10 years post bone marrow transplantation: a case report  

PubMed Central

Introduction Invasive pulmonary aspergillosis is a leading cause of mortality and morbidity in bone marrow transplant recipients. Establishing the diagnosis remains a challenge for clinicians working in acute care setting. However, prompt diagnosis and treatment can lead to favourable outcomes Case presentation We report a case of invasive aspergillosis occurring in a 39-year-old Caucasian female 10 years after an allogeneic haematopoietic bone marrow transplant, and 5 years after stopping all immunosuppression. Possible risk factors include bronchiolitis obliterans and exposure to building dust (for example, handling her husband's dusty overalls). There are no similar case reports in the literature at this time. Conclusion High clinical suspicion, especially in the setting of failure to respond to broad-spectrum antibiotics, should alert clinicians to the possibility of invasive pulmonary aspergillosis, which, in this case, responded to antifungal therapy.

Management of multiple intrusive luxative injuries: A case report with 7-year follow-up  

PubMed Central

This report presents a case of severe intrusive luxation of multiple anterior teeth in an 11-year-old girl. The teeth were repositioned successfully by endodontic and orthodontic management. The case was monitored for 7 years. Depending on the severity of the injury, different clinical approaches for treatment of intrusive luxation may be used. Despite the variety of treatment modalities, rehabilitation of intruded teeth is always a challenge and a multidisciplinary approach is important to achieve a successful result. In this case, intruded teeth were endodontically treated with multiple calcium hydroxide dressings and repositioned orthodontically. The follow-up of such cases is very important as the repair process after intrusion is complex. After 7 years, no clinical or radiographic pathology was detected.

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 PM2.5 impacts and fire policy.  

PubMed

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.

Erythroderma: A clinical study of 97 cases  

PubMed Central

Background Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. Methods We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). Results The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). Conclusion This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs.
