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

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.

Objective To evaluate Candida parapsilosis candidaemia in a neonatal unit over 7?years. Design Case series study. Setting A 2000-bed tertiary-care university hospital at Săo Paulo, Brazil. Participants Neonates hospitalised in a 63-bed neonatal unit. Primary and secondary outcome measures We evaluated the incidence of C parapsilosis fungemia in a neonatal unit from 2002 through 2008 and the main microbiological, clinical and epidemiological aspects of this disease in neonates. During the study period an outbreak occurred, an infection control programme was implemented, and isolates from blood and hand healthcare workers (HCWs) were submitted to molecular typing. Results During 7?years, there were 36 cases of C parapsilosis fungaemia and annual incidence varied from 0 to 19.7 per 1000 admissions. Evaluating 31 neonates with fungemia, the mean age at diagnosis was 19?days. All children except for one were premature; all had received total parenteral nutrition and all but one had used central venous catheter. Three neonates had received antifungal treatment previously to the diagnosis. Thirty-day mortality was 45%. Only lower birthweight was associated with mortality. C parapsilosis species complex was isolated from hand cultures in eight (11%) of the HCWs (one isolate was identified as C orthopsilosis). By molecular typing no HCW isolate was similar to any of the blood isolates. Conclusions The incidence of C parapsilosis fungemia in a neonatal unit varied widely over 7?years. We observed in our series a higher death rate than that reported in European countries and the USA.

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.

Paraplegia at the Tikur Anbessa Teaching Hospital: a seven year retrospective study of 164 cases.  

PubMed

Admission analysis of adult non-traumatic paraplegia and paraparesis from 1981 to 1988 was carried out. Information was collected from charts of 223 consecutive admissions according to a pre-set protocol. Paraplegia or paraparesis was responsible for 164(13.4%) of all neurological admissions over the study period. The median age of the patients was 36 years with a male to female ratio of 1.7:1. Tuberculosis was the leading cause of paraplegia or paraparesis accounting for 47% of the cases. Tumours (20%), Landry-Guillain-Barre' syndrome (12.2%) and tropical spastic paraparesis (TSP) (9.8%) were important but less frequent causes in this series. Other causes like disc prolapse, transverse myelitis, spinal artery stroke and fluorosis were rarely encountered. Vertebral deformity (88.1%), vertebral tenderness (88.1%) and abnormal plain spinal X-ray (89%) were the most helpful findings in the diagnosis of tuberculous paraplegia. Nearly all cases of tuberculous paraplegia were treated medically alone. However, the outcome of treatment as judged by the treating physicians was good with a significant response recorded in 78%.

Aluminium phosphide poisoning: a prospective study of 16 cases in one year.  

PubMed Central

Sixteen patients suffering from aluminium phosphide poisoning were treated during the year from January 1985 to December 1985. These accounted for approximately half the total number of cases of acute poisoning. Profuse vomiting, pain in the upper abdomen and shock were the most common presenting features. Six patients succumbed to their illness. Analysis of various prognostic factors revealed that ingestion of 'unexposed' tablets of aluminium phosphide taken from a freshly opened bottle was associated with a greater risk of fatal outcome. Aluminium phosphide poisoning has become an important matter of public health in parts of India.

14-year follow-up study of a patient with massive calcar resorption. A case report.  

PubMed

The authors present an in-depth clinical, radiographic, and pathologic analysis of a 62-year-old man with massive bone reabsorption around the proximal femur in a total hip arthroplasty (THA). The THA was revised 13 years after implantation. Thirty millimeters of calcar resorption was noted radiographically. Evidence of stem bending was present on examination of the femoral implant, and marked wear of the acetabular cup was noted. The pathologic evaluation of removed calcar bone and cement revealed a histiocytic mass invading the bone. Intracellular and extracellular polymethylene debris was noted within the invasive mass. Evidence of fragmented methylmethacrylate cement was also present. The bone-cement interface in the excised calcar region contained segments that showed active bone remodelling around the cement without an interposed membrane. It is possible that this case of calcar resorption began with histiocytic activation and recruitment by polyethylene wear debris followed by active bone lysis. The process may be perpetuated by the fragmentation of cement, as motion occurred at the calcar bone-cement interface, and may represent an extreme example of a process occurring in cases of calcar resorption in general.

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.

Femoral anastomotic false aneurysms. An 11-year experience analyzed with a case control study.  

PubMed Central

Eighty-three femoral anastomotic false aneurysms occurring in 51 patients were diagnosed from 1972 through 1982. Twenty-two (27%) presented with acute events. Seventy (84%) were confirmed by sonography and/or arteriography. Bilaterality (29%), recurrence (18%), and associated aortic false aneurysms (8%) were significant problems. Eight-one were repaired with a six per cent complication rate, including one death related to preoperative rupture. The 51 patients were evaluated for associated illnesses, risk factors, and etiologies of their false aneurysms. The most common single cause (61%) was host vessel degeneration with an intact suture line remaining attached to a disrupted Dacron limb. Twenty-three patients with host vessel degeneration were matched with case controls not developing false aneurysms. These two groups were matched for gender, age, and year of AFB and compared for associated illnesses and risk factors. Incidences of cigarette smoking, hypertension, cerebrovascular disease, coronary artery disease, diabetes mellitus, previous femoral endarterectomy, outflow disease, other aneurysmal disease, multiple groin operations, wound complications, and training levels of surgeons performing initial AFBs were similar for both groups. Factors observed significantly more often in patients who developed false aneurysms included serum lipid abnormalities (p less than 0.05), braided synthetic suture material as opposed to monofilament polypropylene (p less than 0.05), and continued abuse of tobacco following AFB (p less than 0.005).

A Case Study of Eight First-Year Secondary Science Teachers in North Carolina: Problems, Issues and Behaviors  

NSDL National Science Digital Library

The purpose of this study is to (1) identify some of the major problems confronting first-year secondary science teachers; (2) list supportive practices supplied by the school-based administration and district-wide programs for first-year secondary science teachers; and (3) describe problems of socialization confronting first-year secondary science teachers. The study analyzes perceptions of eight first-year secondary science teachers under contract at the start of the 1996-1997 school year. The study viewed these teachers as novice by definition and perceptions of specific support activities which assisted them in moving from initially licensed to career tenure status. The literature review examines research on teacher based on self-reporting data. Although several of the cited research studies consider first-year teachers in general, few qualitative studies contain specific information on first-year secondary science teachers, e. g., what is involved in the new environment or what developmental skills are needed to survive the year. The research procedure used in this study is the individual case study method. Data were collected primarily through ethnographic interviews and surveys of eight first-year secondary science teachers and six administrators responsible for evaluation of these teachers. (Two administrators did not respond to the survey.) A thematic conceptual matrix was used to display the problems and issues faced by and support offered to these teachers. The findings clearly reveal the top two problems of first-year secondary science teachers to be discipline and classroom/time management exacerbated by a perceived lack of administrative support and assistance.

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.

Threaded acetabular components are widely used in cementless total hip replacement, despite a poor understanding of the nature of the bone-implant interface. We have examined one case in which the threaded titanium ring appeared to be well incorporated with no discernible radiolucency. Microradiography and histology surprisingly showed that the threads were entirely encapsulated in fibrous tissue. This raises doubt about the relevance of plain radiography to the analysis of the acetabular interface. PMID:3346311

Homicide in psychiatric in-patient facilities: a review, a six-year study, and a case report.  

PubMed

Many research studies have attempted to explore the apparent relationship between mental illness and violence. These studies have generally examined the rates of violence during one of three phases: before, after, or during psychiatric hospitalization. Violence that takes place during psychiatric hospitalization has unique implications for both patients, treatment facilities, and for research on violence. This area therefore deserves special study. This article focusses on the most extreme violence that can take place on the wards of a psychiatric facility, assaults resulting in death. This article reviews the literature in this area, reports on a study of the incidence of such occurrences in New York State, and reports in some detail on an additional case which occurred prior to the period under study. The study presented here found that amongst all psychiatric facilities in New York State in six year period there were three cases of in-patient homicide. An average of approximately 90,000 people were served within these facilities during each of the years under study. Suggestions are made for further research in this area. PMID:7782748

A case of primary progressive aphasia. A 14-year follow-up study with neuropathological findings.  

PubMed

Primary progressive aphasia has been clinically defined as a progressive language deficit leading to the dissolution of almost all language functions with relative preservation of other cognitive functions until late in the course of the disease. Two types of language impairment have been described for primary progressive aphasia, which differ with respect to the degree of fluency of spontaneous speech. Whereas some authors have emphasized non-fluency as a defining characteristic of primary progressive aphasia, others have proposed that phonemic rather than semantic paraphasias in naming, both in the fluent and the non-fluent subtype, should be used as a criterion to distinguish primary progressive aphasia from slowly progressive aphasia in other forms of degenerative brain disease. Patients with fluent speech and semantic dementia, as typically seen in Alzheimer's disease, produce semantic paraphasias and circumlocutions rather than phonemic errors in naming. This paper reports the long-term follow-up of a patient with fluent aphasic speech, whose language profile over a decade was similar to that of patients with semantic dementia. Neuropathological examination revealed no evidence of Alzheimer's disease. Pick's disease or Pick variant, but showed spongiform changes of cortical layers (II and III) in temporal and, less severely, in frontal gyri. The present case indicates that semantic dementia is not a reliable indicator of probable Alzheimer's disease and supports the notion that there are different subtypes of primary progressive aphasia which cannot be defined by fluency or by the presence of phonemic paraphasia. Progress in identifying the neuropathological correlates of these subtypes in cases with lobar atrophy and spongiform changes should be expected from hereditary variants of progressive disorder.

Maturation to elite status: a six-year physiological case study of a world champion rowing crew.  

PubMed

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

Does cadmium pollution affect reproduction in the clam Ruditapes decussatus? A one-year case study.  

PubMed

The effect of cadmium (Cd) on the reproduction of Ruditapes decussatus was monitored over a period of 12 months, from June 2001 to June 2002. Two sites "Bordj d'Ungha" and "El Hofra" differing by their degree of cadmium contamination were chosen in the Gulf of Gabčs area (Tunisia). Annual mean concentrations of Cd in the whole soft tissues of clams from the site El Hofra were more than 4 times higher than those from the site Bordj d'Ungha (reference site). The gametogenic cycle of the clam R. decussatus was also investigated by histological examination and monthly observations of gonadal sections in a population of clams from both sites. The results show that gametogenesis occurred from March to December in clams from both sites. Nevertheless, spawning and emission of gametes were synchronized in both sexes from only the clams of the reference site. Although this species is considered as gonochoristic, 6.6% of hermaphroditic cases were observed in clams from both sites in which gametes of both males and females were in ripe stage. Moreover, the period of ripening of sexual products led to an increase of condition index and to a decrease of Cd concentrations in the whole soft tissues of clams from both sites, hence reflecting the phenomenon of "biological dilution".

Case-control study on risk factors for leukaemia and brain tumours in children under 5 years in Germany.  

PubMed

In the context of a case control study on the cancer risk for children under five by distance to the nearest nuclear power plant, we collected information on other risk factors in a subset. We present the interview study as if it had been an independent study. Parents of 471 cases with Leukaemia, Lymphoma or CNS (Central Nervous System)-tumour from the German Childhood Cancer Registry, diagnosed at age under 5 in the years 1993-2003, and 1,457 matched controls were to be interviewed. For Leukaemia, 243 cases/604 controls, and for CNS 102 cases/246 controls participated, lymphoma cases were too few. Questions related to social status, ionizing radiation, pregnancy and birth, immune system, and selected toxins. The analysis is exploratory in nature; variables were selected by backward elimination. For leukaemia we found a significant protective effect of social contacts (OR=0.50, 95% CI [0.29;0.87]) and a risk for high birth weight (OR=1.96 95% CI [1.12;3.41] comparing >4,000 g to "normal"). We could not reproduce other associations reported in the literature such as a negative association with allergies. For CNS tumours we found a significant protective effect of social contacts (OR=0.30 95% CI [0.13;0.72]), of pesticides and herbicides (OR=0.39 95% CI [0.18;0.83]) and an increased risk for low birth weight (p=0.0232). This study on risk factors for childhood leukaemia and brain tumours is relatively small and exploratory. We could reproduce some major associations reported in the literature (leukaemia: social contacts and high birth weight) but not others. Some observations may be reporting artefacts or self selection artefacts. PMID:19890788

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.

[Cement burns: A 10-year retrospective study in our burn unit. About 55 cases.  

PubMed

SUBJECT: Although cement burns represents only a small percentage of admissions to burn centers, their diagnosis and treatment are specific. Our retrospective study concerns all patients treated for cement burns in our unit between 1999 and 2009. This is the largest series described. PATIENTS AND METHOD: Fifty-five patients, aged from 23 to 63, were treated in our burn unit from 1999 to 2009. A review of medical and socioeconomic data was made from computer data files. RESULTS: This population is predominantly male, young and active. These burns occurred mainly in a domestic accident situation (78.2%). Burns were limited but deep and concerned especially lower limbs. The average duration of treatment was 39days. Forty-four patients were treated medically. The mean duration of sick live for these patients was 63 days. It was only of 21 days for those treated surgically. Aesthetic and functional sequelae were present in 88% of medically treated patients and in 18% of patients treated surgically. CONCLUSION: This study demonstrates that early surgical diagnosis and the coverage (care) of these burns allows to limit the socioeconomic echo and to reduce the risk of after-effects for this population of patients mainly young and active. The necessity of strengthening the precautionary measures with these users who are informed enough about the risks incurred during the misuse of the cement is also a reality. PMID:23122531

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.

Autoimmune haemolysis: an 18-year study of 865 cases referred to a regional transfusion centre.  

PubMed Central

Clinical and serological records of 865 patients with confirmed autoimmune haemolysis (AIH)--a much larger series than any previously reported--were critically reviewed nd analysed. A proposed new classification for AIH based on serological findings differs from traditional classifications in that a new category of "mixed" AIH has been defined in which both "warm" and "cold" autoantibodies are present, and both are capable of causing haemolysis. Patients in this mixed group tend to have severe disease that may run a chronic intermittent course. The presentation of cold agglutinin disease is much more variable than has been seen in previous studies, haemolysis due to low titre autoantibodies being common. The AIH associated with pregnancy, usually considered as being of bad prognosis, is often mild and self limiting in the absence of other associated disorders.

High Dengue Case Capture Rate in Four Years of a Cohort Study in Nicaragua Compared to National Surveillance Data  

PubMed Central

Dengue is a major public health problem in tropical and subtropical regions; however, under-reporting of cases to national surveillance systems hinders accurate knowledge of disease burden and costs. Laboratory-confirmed dengue cases identified through the Nicaraguan Pediatric Dengue Cohort Study (PDCS) were compared to those reported from other health facilities in Managua to the National Epidemiologic Surveillance (NES) program of the Nicaraguan Ministry of Health. Compared to reporting among similar pediatric populations in Managua, the PDCS identified 14 to 28 (average 21.3) times more dengue cases each year per 100,000 persons than were reported to the NES. Applying these annual expansion factors to national-level data, we estimate that the incidence of confirmed pediatric dengue throughout Nicaragua ranged from 300 to 1000 cases per 100,000 persons. We have estimated a much higher incidence of dengue than reported by the Ministry of Health. A country-specific expansion factor for dengue that allows for a more accurate estimate of incidence may aid governments and other institutions calculating disease burden, costs, resource needs for prevention and treatment, and the economic benefits of drug and vaccine development.

Case Study of the Development of an Infant with Autism from Birth to Two Years of Age  

PubMed Central

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

A 10 year follow-up study after Roux-Elmslie-Trillat treatment for cases of patellar instability  

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.

Learning in-the-making: A case study of science and technology projects in a year six classroom  

NASA Astrophysics Data System (ADS)

The integration of technology-based projects in the primary science curriculum has attracted recent international attention. Yet few case studies about what and how knowledge is constructed in this context have been reported. In this interpretive study of a Year Six classroom, we focused on how two contrasting groups of children designed ill-defined engineering structures. Of particular interest was how the groups appropriated ideas into their designs and constructed related scientific concepts. Our interpretations of the field, videotape and interview data during the semester-long observation period highlight the value of building learning communities in science and technology classes. As well as reporting our classroom-related findings we begin to explore the collaboration processes within our research team. A thick description of the genesis of the project and a brief revelation about our interpretive zone are provided.

A survey on spinal cord injuries resulting from stabbings; a case series study of 12 years' experience  

PubMed Central

Abstract: Background: Penetrating spinal cord injuries (SCIs) are an uncommon injury and not reported very frequently. SCIs cause sensory, motor and genitourinary system problems or a combination of sensorimotor dysfunctions. These are among the most debilitating kinds of disorders and negatively affect quality of life, not only for the patient, but also for their family members. Therefore, the present study aims to evaluate complete or incomplete SCIs and the course of the injury and the prognosis for SCIs caused by stab wounds. Methods: This case-series design study was performed on 57 patients attending the emergency department of Taleqani Trauma Center (Kermanshah, Iran) due to SCIs caused by violent encounters involving sharp objects such as a knife, dagger, whittle and Bowie-knife between 1999 and 2011. An assessment of sensory and motor functions was performed as part of the neurological examination on admission, and during the treatment, using the Frankel Classification grading system, and the results were recorded. Results: The average age of patients was 27 years (SD= 7.9, Range=17 to 46 years). The results of the study showed a proportion of cervical, thoracic and lumbar injuries of 23 (40%), 24 (42%) and 10 (18%), respectively. There was no case of cerebrospinal fluid leakage (CSF) or infection at the wound site in the subjects. Regarding the extent of the SCI, the combined neurological assessment showed that several patients (43%) had a complete SCI with no sensory and motor functions in the sacral segments and the segments below the site of injury. In 32 patients (57%) incomplete injuries were observed; i.e. they showed only some degrees of sensory-motor functions that were below the neurological level. Conclusions: Both complete and incomplete SCIs are of great importance because the prognosis of SCI is directly associated with the location and extent of injury. It should be considered that partial recovery from SCIs is possible in few cases of complete injuries. Therefore, all the patients should be treated carefully and seriously.

Legionella pneumonia cases over a five-year period: a descriptive, retrospective study of outcomes in a UK district hospital.  

PubMed

As the recent outbreaks in Edinburgh and Camarthen, UK, have shown, Legionella pneumonia (LP) remains a significant public health problem, which is not only confined to those who have travelled abroad. In both outbreaks and sporadic cases, diagnosis can go unrecognised. We reviewed the demographics, comorbidities, diagnosis, treatment and clinical outcome of LP cases over five years in a district general hospital in northwest England. Over half of LP cases were UK acquired and 'classic' clinical features were common. Clinical criteria for diagnosing LP were confirmed, but few sputum samples were sent to reference laboratories, limiting further essential epidemiological mapping of UK cases. Following current UK community-acquired pneumonia guidance would have missed nearly one quarter of LP cases in our series, potentially leading to further morbidity and mortality. PMID:23681863

Intracardiac fistulas are rare complications of infective endocarditis. We report an unusual case of successful surgical repair of intracardiac fistula between the left ventricle and the left atrium in the course of infective endocarditis in a 20-year-old patient. According to this we conclude that timely diagnosis, proper antibiotic treatment, and early surgical intervention should improve the outcomes of infective endocarditis complications.

Sudden Unexpected Deaths and Vaccinations during the First Two Years of Life in Italy: A Case Series Study  

PubMed Central

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

Frequency of contact with community-based psychiatric services and the lunar cycle: a 10-year case-register study.  

PubMed

The relationship between the lunar cycle and the frequency of contact with community-based psychiatric services was assessed using the South Verona Psychiatric Case Register data. For each day of the study period (January 1982-December 1991) we recorded the number of contacts made by South Verona residents with psychiatric services and the corresponding day of the lunar cycle. First, the synodic month was divided into four interval phases (usually called new moon, first quarter, full moon and third quarter), and interphase differences in the mean number of contacts were tested using one-way analysis of variance. Second. the null hypothesis of no relationship between the lunar cycle and the frequency of contact with psychiatric services was tested against the alternative hypothesis of a sinusoidal distribution according to the lunar phase. The average number of contacts with psychiatric services on each day of the lunar cycle over the 10-year period was obtained and a sine-wave curve was fitted to the data. Both for total and drop-in contacts, no significant differences in mean number of contacts were found between the four interval phases of the synodic month (new moon, first quarter, full moon and third quarter). Similarly, no significant results were found by setting the expected surge in consultations at 1-3 days after the full moon and the period of the sine-wave curve equal to 30 days. When the period of the sine-wave curve was allowed to vary in order to fit the data best, none of the statistical tests reached the level of significance required to dismiss the possibility of false-positive results. These findings did not support the theory that a relationship exists between the lunar cycle and the frequency of contact with community-based psychiatric services. PMID:9299925

Treatment of a severe conversion disorder in a 10-year-old boy: a case study and overview.  

PubMed

Conversion disorder (CD) in children remains a major challenge both in pediatric and mental health clinics and is still a prevalent psychiatric disorder in developing countries. The authors describe a 10-year-old boy with the complaints of inability to walk, speak or eat, excessive drooling, urinary and fecal incontinence, disturbance from light and sound, and expression of needs only by eye movements. The patient diagnosed with CD was followed by the Department of Child and Adolescent Psychiatry with play therapy, individual psychotherapy and family therapy. At the end of three months, the patient was discharged. This is one of the most challenging cases of CD in children. The most important aim of the treatment is to understand the need for conversion symptoms and to constitute a healthy psychological environment for the child rather than to remove the physical symptoms.

Prospective study of IL-18 and risk of MI and stroke in men and women aged 60-79 years: A nested case-control study  

PubMed Central

Aim IL-18 is hypothesized to destabilise atherosclerotic plaques, leading to thrombotic events and epidemiologic studies suggest that IL-18 may increase risk of CHD or CVD. We examined prospective associations between levels of serum IL-18 and new CHD and stroke events in older men and women from a general population. Methods A case-control study was nested within a prospective cohort of men and women aged 60–79 years recruited from general practices in 25 British towns in 1998–2000 and followed-up for 7.5 years for fatal and non-fatal MI and stroke. Baseline IL-18 was measured in stored serum samples of incident cases of MI (n = 364) or stroke (n = 300) and two controls per case. Results Geometric mean IL-18 levels were higher among the 364 MI cases than the 706 controls; 417.84 pg/mL (IQR 316.25, 537.44) compared to 386.90 pg/mL (IQR 296.54, 482.33), p(difference) = 0.002. IL-18 was positively associated with adverse lipid and inflammatory profiles. Men and women in the top third of baseline IL-18 levels had an age and sex-adjusted odds ratio (OR) for MI of 1.31 (95%CI 0.92, 1.85) compared with those in the lowest third; this attenuated to 1.05 (95%CI 0.72, 1.53) after additional adjustment for established vascular and inflammatory risk factors. Each doubling of IL-18 level was associated with an increased OR for MI 1.34 (95%CI 1.04, 1.72), which was attenuated on adjustment for established vascular and inflammatory risk factors; 1.09 (95%CI 0.83, 1.44). Geometric mean IL-18 levels did not differ between stroke cases and controls. The OR for stroke associated with the highest compared to the lowest tertile of IL-18 was 1.24 (95%CI 0.84, 1.84). Results for MI and stroke did not differ by presence of pre-existing CVD, gender or age. Conclusions Circulating IL-18 levels were strongly associated with a range of established and novel risk factors but were not independently associated with risk of MI or stroke in our study.

Seroprevalence and Trend of Dengue Cases Admitted to a Government Hospital, Delhi - 5-Year Study (2006-2010): A Look into the Age Shift  

PubMed Central

Background: Diagnosis of dengue infection is easily and best accomplished by demonstration of specific IgM antibodies in blood. We analyzed retrospectively the dengue IgM seropositivity available for samples obtained over a period of 5 years (2006–2010) from patients with suspected dengue fever (DF)-like illness to investigate whether there was an overall increase in the dengue IgM prevalence over this period. Methods: Blood samples were collected from patients with DF-like febrile illnesses attending the Pediatric, Medicine, and Fever clinics of a Government hospital, Delhi. A total of 8138 individuals (suspected dengue cases) obtained over 5 years were tested for dengue specific IgM antibodies. Year wise, month wise, and age wise data on geographic distribution and clinical manifestations were analyzed. Results: Of the 8138 samples, 1600 (19.66%) were positive for dengue specific IgM. The year 2006 had the highest number of reported cases, 761 (46.23%). In our study, the age group most commonly affected of all 5 years was 11–20 years. Out of the total 1600 cases admitted to the hospital between 2006 and 2010, 279 (58.9%) had DF, 178 (37.6%) had dengue hemorrhagic fever, and 16 (3.38%) had dengue shock syndrome. We found a high burden of dengue in young children and late adolescents in both rural and urban communities at a magnitude greater than previously described. Interpretation and Conclusion: We observed an increase in the dengue positive cases every alternate year, thereby indicating a possible role of herd immunity in northern India. We did not find a steady increase in the number of cases over 5 years. We found an increase in the number of positive cases in children and young adolescents.

Forty-five years of keratoprosthesis study and application at the Filatov Institute: a retrospective analysis of 1 060 cases  

PubMed Central

AIM To present results of the keratoprosthesis method used at The Filatov Institute of Eye Diseases and Tissue Therapy. METHODS A retrospective case series analysis was used to describe the development of new types of keratoprostheses and methods of implantation as well as different ways of leukoma strengthening. RESULTS Keratoprosthesis was performed in 1 060 eyes of 1 040 patients with leukomas of different etiology: burns, 725 eyes (68.4%); trauma, 120 eyes (11.3%); keratitis and ocular pemphigoid, 108 eyes (10.2%); and bullous keratopathy, 107 eyes (10.1%). Visual acuity before keratoprosthesis consisted of light perception in 962 eyes (92%), and 98 eyes (8%) had minimal visual acuity (1/200-1/50). Both eyes were blind (visual acuity less than 1/200) in 955 patients (91.8%). The period of blindness varied from 1 to 52 years. As a result of keratoprosthesis, visual acuity of ?1/200 was restored in 1 023 of 1 060 eyes (96.5%). Visual acuity of 20/200-20/20 was achieved in 716 eyes (67.5%). At the last follow-up visit visual acuity of ?1/200 was preserved in 806 eyes (76%), visual acuity of 20/200-20/20 was measured in 583 of 1 060 eyes (55%) and good keratoprosthesis fixation in the cornea was achieved in 986 of 1 060 eyes (93%). The minimal follow-up was 12 months (range, 12 months to 37 years, median 5 years). CONCLUSION Our techniques of keratoprosthesis effectively restore vision in patients with leukomas that cannot be treated by optical corneal grafting.

A case study of the Physics Enhancement Project for Two Year Colleges, its effects and outcomes on the teaching of undergraduate physics at two year colleges  

NASA Astrophysics Data System (ADS)

This dissertation reports on a naturalistic evaluation study of a series of NSF grant projects collectively known as PEPTYC -- Physics Enhancement Project for Two Year College Physics Instructors. The project encompassed seven different cycles of professional development occurring during the 1990's via May Institutes, held at Texas A&M University. Follow-up meetings were held at American Association of Physics Teachers - Texas Section Meetings. The research was conducted post hoc. The research evaluated the characteristics of effective professional development under an evaluation frame work designed by D.L. Kirkpatrick (1959) and adapted by the researcher to address issues that are pertinent to the professional development of faculty. This framework was adapted to be viewed through an educator's eye in an effort to ascertain the long term affects of the program and determine how the program affected the participants' attitudes, pedagogical knowledge, and instructional practices. The PEPTYC program philosophy was based on the premise, supported by research, that professional development programs addressing specific teaching practices are more successful than generic programs. Furthermore, professional development is more effective in helping teachers use alternative approaches when teachers are engaged in active learning experiences rather than passively listening to lectures or presentations. The naturalistic study was based on surveys and semi-structured interviews with 14 individuals who participated in PEPTYC workshops, as well as presenters of the PEPTYC program. The interviews were analyzed to describe how the PEPTYC project influenced the participants long after they had completed their training. This project can inform the development of similar evaluation studies of other professional development programs.

Spatial analysis of rockfall activity, bounce heights and geomorphic changes over the last 50 years A case study using dendrogeomorphology  

NASA Astrophysics Data System (ADS)

Tree-ring series have been used to reconstruct 50 years of rockfall behavior on a slope near Saas Balen (Swiss Alps). A total of 796 cores and 141 cross sections from 191 severely injured conifer trees ( Larix decidua Mill., Picea abies (L.) Karst. and Pinus cembra L.), combined with a series of aerial photographs, were used to investigate the evolution of the forest stand so as (i) to reconstruct past rockfall rates; (ii) to analyze the spatial behavior of maximum bounce heights; and (iii) to analyze the spatial comportment of rockfall activity over the last five decades. Tree-ring analysis permitted the reconstruction of the age distribution at the study site; results were in perfect agreement with the afforestation process shown in the aerial photographs. The oldest are located in the lower, central part of the study site; the youngest individuals at its uppermost lateral boundaries. Reconstructed rockfall rates reveal strong interannual variations and single event years with increased activity, namely in 1960/1961 and 1995. Spatial analysis of the maximum bounce heights indicate highest values at the lateral boundaries and lowest heights in the lower central part of the forest stand, where a big boulder seems to shield trees growing below it. The spatial analysis of past rockfall activity shows high active zones at the uppermost north-facing boundaries of the forest and least active zones in the lowermost central part of the studied stand. The high rockfall activity at the slope is expressed by a mean rockfall rate of > 1 event m - 1 y - 1 .

Incidence of graft rupture 15 years after bilateral anterior cruciate ligament reconstructions: a case-control study.  

PubMed

Between 1993 and 1994, 891 patients underwent primary anterior cruciate ligament (ACL) reconstruction. A total of 48 patients had undergone bilateral ACL reconstruction and 42 were available for review. These patients were matched to a unilateral ACL reconstruction control group for gender, age, sport of primary injury, meniscal status and graft type. At 15-year follow-up a telephone interview with patients in both groups was performed. The incidence of further ACL injury was identified through structured questions and the two groups were compared for the variables of graft rupture or further ACL injury, family history of ACL injury, International Knee Documentation Committee (IKDC) subjective score and activity level. There were 28 male and 14 female patients with a mean age of 25 years (13 to 42) at the time of first ACL injury. Subsequent further ACL injury was identified in ten patients (24%) in the bilateral ACL reconstruction study group and in nine patients (21%) in the unilateral ACL reconstruction control group (p = 0.794). The mean time from bilateral ACL reconstruction to further ACL injury was 54 months (6 to 103). There was no significant difference between the bilateral ACL reconstruction study group and the matched unilateral ACL reconstruction control group in incidence of further ACL injury (p = 0.794), family history of ACL injury (p = 0.595), IKDC activity level (p = 0.514), or IKDC subjective score (p = 0.824). After bilateral ACL reconstruction the incidence of graft rupture and subjective outcomes were equivalent to that after unilateral ACL reconstructions. PMID:23723275

Cognitive impairment 3 years after neurological Varicella-zoster virus infection: a long-term case control study.  

PubMed

Varicella-zoster virus (VZV) is one of the most common viruses causing central nervous system (CNS) infection, sometimes with severe neurological complications and sequelae despite appropriate antiviral treatment. Whether the neurological sequelae of VZV CNS infections include long-term cognitive impairment and how this impairment might affect the patients is still largely unknown. In this study, 14 patients with predominant CNS manifestations caused by VZV infection underwent cognitive testing 3 years (median 39.5 months, range 31-52 months) after acute disease. The results were compared with those for 28 controls, matched for age and gender. The tests covered the cognitive domains of speed and attention, memory and learning, visuospatial function, language and executive function. To further assess the cognitive dysfunction caused by neurological VZV infection, patients were classified into the concept of mild cognitive impairment (MCI), which is associated with development of dementia in other pathologies. The VZV patients performed significantly worse than controls on four tests covering the domains of speed and attention, memory and learning and executive function. The cut-off was set at 1.5 SD below mean age. In addition, a greater proportion of VZV patients were classified with MCI as compared with controls. In conclusion, patients with previous VZV infection affecting the brain had signs of long-term cognitive impairment in the domains of speed and attention, memory and learning and executive function. However, larger study populations are needed to confirm these results. PMID:23900759

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

NSDL National Science Digital Library

The Maryland Physics Expectations (MPEX) survey was designed to probe studentsâ expectations about their understanding of the process of learning physics and the structure of physics knowledgeâcognitive 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 studentsâ normalized gains from pre and post Force and Motion Conceptual Evaluation (FMCE) results, which measure studentsâ conceptual understanding, and (2) studentâs 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 studentsâ 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.

Epithelioid sarcoma in childhood: An immunohistochemical, electron microscopic, and clinicopathologic study of 11 cases under 15 years of age and review of the literature.  

PubMed

Epithelioid sarcoma in a rare tumor and most of the cases occur in young adults. It is rare in childhood. We have been able to obtain data and histologic material for 11 patients with this disease. The primary sites were head and neck in three patients, inguinal region in one, and extremities in seven. The age range of the patients was 12 weeks to 13 years. There was a preponderance of males over females with a ratio of 1.75. The tumors presented with a typical nodular necrotizing pattern. In three cases giant osteoclast-like cells were present. The immunohistochemistry and electron microscopy showed features consistent with previous observations on epithelioid sarcomas. In one case islands of small dark cells noted on light microscopy were surrounded by basal lamina on electron microscopy. The cells inside the nests were undifferentiated. Six tumors studied by flow cytometry were in DNA diploid range. On follow-up, five children are alive and well 2 to 7 years after treatment. Three children died of tumor progression with metastases to lymph nodes and lungs. One child had been diagnosed only recently, and in one the disease has run a protractive course with multiple recurrences. The behavior of these epithelioid sarcomas in children is similar to that seen in adults, the prognosis being dependent on radical tumor surgery preventing recurrent disease. Long-term follow-up is necessary because the tumor may recur many years after the primary tumor was removed. PMID:7520581

The association between malaria parasitaemia, erythrocyte polymorphisms, malnutrition and anaemia in children less than 10 years in Senegal: a case control study  

PubMed Central

Background Malaria and anaemia (Haemoglobin <11 g/dl) remain frequent in tropical regions and are closely associated. Although anaemia aetiologies are known to be multi-factorial, most studies in malaria endemic areas have been confined to analysis of possible associations between anaemia and individual factors such as malaria. A case control study involving children aged from 1 to 10 years was conducted to assess some assumed contributors to anaemia in the area of Bonconto Health post in Senegal. Methods Study participants were randomly selected from a list of children who participated in a survey in December 2010. Children aged from 1 to 10 years with haemoglobin level below 11 g/dl represented cases (anaemic children). Control participants were eligible if of same age group and their haemoglobin level was >= 11 g/dl. For each participant, a physical examination was done and anthropometric data collected prior to a biological assessment which included: malaria parasitaemia infection, intestinal worm carriage, G6PD deficiency, sickle cell disorders, and alpha-talassaemia. Results Three hundred and fifty two children < 10 years of age were enrolled (176 case and 176 controls). In a logistic regression analysis, anaemia was significantly associated with malaria parasitaemia (aOR=5.23, 95%CI[1.1-28.48]), sickle cell disorders (aOR=2.89, 95%CI[1,32-6.34]), alpha-thalassemia (aOR=1.82, 95%CI[1.2-3.35]), stunting (aOR=3.37, 95%CI[1.93-5.88], age ranged from 2 to 4 years (aOR=0.13, 95%CI[0.05-0.31]) and age > 5 years (aOR=0.03, 95%CI[0.01-0.08]). Stratified by age group, anaemia was significantly associated with stunting in children less than 5 years (aOR=3.1 95%CI[1.4 – 6.8]), with, sickle cell disorders (aOR=3.5 95%CI [1.4 – 9.0]), alpha-thalassemia (or=2.4 95%CI[1.1–5.3]) and stunting (aOR=3.6 95%CI [1.6–8.2]) for children above 5 years. No association was found between G6PD deficiency, intestinal worm carriage and children’s gender. Conclusion Malaria parasitaemia, stunting and haemoglobin genetic disorders represented the major causes of anaemia among study participants. Anaemia control in this area could be achieved by developing integrated interventions targeting both malaria and malnutrition.

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.

Case-control study of leukaemia and non-Hodgkin's lymphoma among children aged 0-4 years living in west Berkshire and north Hampshire health districts.  

PubMed Central

OBJECTIVE--To investigate the relation between parental employment in the nuclear industry and childhood leukaemia and non-Hodgkin's lymphoma. DESIGN--Case-control study. SETTING-West Berkshire and Basingstoke and North Hampshire District Health Authorities. SUBJECTS--54 children aged 0-4 years who had leukaemia or non-Hodgkin's lymphoma diagnosed during 1972-89, who were born in the study area and were resident there when cancer was diagnosed. Six controls were selected for each case: four from hospital delivery registers and two from livebirth registers maintained by the NHS central register. Controls were matched for sex, date of birth (within six months), and area of residence at birth and time of diagnosis. MAIN OUTCOME MEASURES--Parents' employment by the nuclear industry and exposure to ionising radiation at work. RESULTS--Five (9%) of the 54 cases and 14 (4%) of the 324 controls had fathers or mothers, or both, who had been employed by the nuclear industry (relative risk 2.2, 95% confidence interval 0.6 to 6.9). Nuclear industry employees who work in areas where exposure to radiation is possible are given film badges to monitor their exposure to external penetrating ionising radiation. Three fathers of cases and two fathers of controls (and no mothers of either) had been monitored in this way before their child was conceived (relative risk 9.0, 95% confidence interval 1.0 to 107.8). No father (of a case or control) had accumulated a recorded dose of more than 5 mSv before his child was conceived, and no father had been monitored at any time in the four years before his child was conceived. A dose-response relation was not evident among fathers who had been monitored. CONCLUSIONS--These results suggest that the children of fathers who had been monitored for exposure to external penetrating ionising radiation in the nuclear industry may be at increased risk of developing leukaemia before their fifth birthday. The finding is based on small numbers and could be due to chance. If the relationship is real the mechanisms are far from clear, except that the effect is unlikely to be due to external radiation; the possibility that it could be due to internal contamination by radioactive substances or some other exposure at work should be pursued. The above average rates of leukaemia in the study area cannot be accounted for by these findings.

MC1R genotypes and risk of melanoma before age 40 years: a population-based case-control-family study.  

PubMed

The contribution of melanocortin-1 receptor (MC1R) gene variants to the development of early-onset melanoma is unknown. Using an Australian population-based, case-control-family study, we sequenced MC1R for 565 cases with invasive cutaneous melanoma diagnosed between ages 18 and 39 years, 409 unrelated controls and 518 sibling controls. Variants were classified a priori into "R" variants (D84E, R142H, R151C, I155T, R160W, D294H) and "r" variants (all other nonsynonymous variants). We estimated odds ratios (OR) for melanoma using unconditional (unrelated controls) and conditional (sibling controls) logistic regression. The prevalence of having at least one R or r variant was 86% for cases, 73% for unrelated controls and 81% for sibling controls. R151C conferred the highest risk (per allele OR 2.57, 95% confidence interval 1.86-3.56 for the case-unrelated-control analysis and 1.70 (1.12-2.60) for the case-sibling-control analysis). When mutually adjusted, the ORs per R allele were 2.23 (1.77-2.80) and 2.06 (1.47-2.88), respectively, from the two types of analysis, and the ORs per r allele were 1.69 (1.33-2.13) and 1.25 (0.88-1.79), respectively. The associations were stronger for men and those with none or few nevi or with high childhood sun exposure. Adjustment for phenotype, nevi and sun exposure attenuated the overall log OR for R variants by approximately 18% but had lesser influence on r variant risk estimates. MC1R variants explained about 21% of the familial aggregation of melanoma. Some MC1R variants are important determinants of early-onset melanoma. The strength of association with melanoma differs according to the type and number of variants. PMID:22095472

A twelve-year follow-up study on a case of early-onset parkinsonism preceding clinical manifestation of Gaucher disease.  

PubMed

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

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.

Case management in oncology rehabilitation (CAMON): The effect of case management on the quality of life in patients with cancer after one year of ambulant rehabilitation. A study protocol for a randomized controlled clinical trial in oncology rehabilitation  

PubMed Central

Background Cancer diseases and their therapies have negative effects on the quality of life. The aim of this study is to assess the effectiveness of case management in a sample of oncological outpatients with the intent of rehabilitation after cancer treatment. Case management wants to support the complex information needs of the patients in addition to the segmented structure of the health care system. Emphasis is put on support for self-management in order to enhance health - conscious behaviour, learning to deal with the burden of the illness and providing the opportunity for regular contacts with care providers. We present a study protocol to investigate the efficacy of a case management in patients following oncology rehabilitation after cancer treatment. Methods The trial is a multicentre, two-arm randomised controlled study. Patients are randomised parallel in either 'usual care' plus case management or 'usual care' alone. Patients with all types of cancer can be included in the study, if they have completed the therapy with chemo- and/or radiotherapy/surgery with curative intention and are expected to have a survival time >1 year. To determine the health-related quality of life the general questionnaire FACT G is used. The direct correlation between self-management and perceived self-efficacy is measured with the Jerusalem & Schwarzer questionnaire. Patients satisfaction with the care received is measured using the Patient Assessment of Chronic Illness Care 5 As (PACIC-5A). Data are collected at the beginning of the trial and after 3, 6 and 12 months. The power analysis revealed a sample size of 102 patients. The recruitment of the centres began in 2009. The inclusion of patients began in May 2010. Discussion Case management has proved to be effective regarding quality of life of patients with chronic diseases. When it comes to oncology, case management is mainly used in cancer treatment, but it is not yet common in the rehabilitation of cancer patients. Case management in oncology rehabilitation is not well-established in Switzerland. A major challenge of the study will therefore probably be the recruitment of the patients due to the physicians' and patients' scarcely existing awareness of this issue.

The case study approach  

PubMed Central

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

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.

The curious 2000-year case of asthma.  

PubMed

Millions worldwide have asthma, with the numbers succumbing increasing sharply in the past two decades. After 2000 years of scientific study, who succumbs to asthma when is as puzzling as who regains health when and how. The discipline of psychosomatic medicine and science investigates and treats diseases like asthma that typically confound general medicine. Still psychosomatic medicine, like general medicine, only manages but does not remedy asthma, which can currently only be in remission but not cured. This historical review reveals the progress and missteps that have been made in the study and treatment of asthma by comparing the general medicine approach with the major research findings on asthma published over 60 years in Psychosomatic Medicine. Research has identified antecedent, collateral, and subsequent factors to scientifically describe and control this disease in terms of diagnosis, management, and treatment. Paradoxically and regrettably, the prognosis for those with asthma is worse than ever. Curious also that a noninfectious disease should spread so rapidly and mostly for specific groups identified by variables like age, gender, ethnicity, and socioeconomic status. Furthermore, partial, not full, family concordance indicates merely genetic influence, not determination. General medicine now focuses on enumerating the range of environmental and situational triggers, or stimuli, producing asthma and describing the pathophysiology of bronchial inflammation. With a more comprehensive multifactorial approach, psychosomatic medicine seems well suited to investigate further the physiological, psychological, social, and environmental factors implicated in this medical conundrum. A future challenge for psychosomatic medicine is to stem the tide of rising prevalence and cure the disease of asthma. PMID:11139002

SULT1A1 genotype, active and passive smoking, and breast cancer risk by age 50 years in a German case-control study  

PubMed Central

Introduction Sulfotransferase 1A1 (encoded by SULT1A1) is involved in the metabolism of procarcinogens such as heterocyclic amines and polycyclic aromatic hydrocarbons, both of which are present in tobacco smoke. We recently reported a differential effect of N-acetyltransferase (NAT) 2 genotype on the association between active and passive smoking and breast cancer. Additional investigation of a common SULT1A1 genetic polymorphism associated with reduced enzyme activity and stability might therefore provide deeper insight into the modification of breast cancer susceptibility. Methods We conducted a population-based case–control study in Germany. A total of 419 patients who had developed breast cancer by age 50 years and 884 age-matched control individuals, for whom risk factor information and detailed smoking history were available, were included in the analysis. Genotyping was performed using a fluorescence-based melting curve analysis method. Multivariate logistic regression analysis was used to estimate breast cancer risk associated with the SULT1A1 Arg213His polymorphism alone and in combination with NAT2 genotype in relation to smoking. Results The overall risk for breast cancer in women who were carriers of at least one SULT1A1*2 allele was not significantly different from that for women with the SULT1A1*1/*1 genotype (adjusted odds ratio 0.83, 95% confidence interval 0.66–1.06). Risk for breast cancer with respect to several smoking variables did not differ substantially between carriers of the *2 allele and noncarriers. However, among NAT2 fast acetylators, the odds ratio associated with passive smoking only (3.23, 95% confidence interval 1.05–9.92) was elevated in homozygous carriers of the SULT1A1*1 allele but not in carriers of the SULT1A1*2 allele (odds ratio 1.28, 95% confidence interval 0.50–3.31). Conclusion We found no evidence that the SULT1A1 genotype in itself modifies breast cancer risk associated with smoking in women up to age 50 years. In combination with NAT2 fast acetylator status, however, the SULT1A1*1/*1 genotype might increase breast cancer risk in women exposed to tobacco smoke.

Case-control study of hospital admission with asthma in children aged 5-14 years: relation with road traffic in north west London  

PubMed Central

BACKGROUND—Evidence for an association between road traffic pollution and asthma is inconclusive. We report a case-control study of hospital admissions for asthma and respiratory illness among children aged 5-14 in relation to proxy markers of traffic related pollution.?METHODS—The study was based on routine hospital admissions data in 1992/3 and 1993/4 for North Thames (West) health region within the M25 motorway. Cases were defined as emergency admissions for asthma (n = 1380) or all respiratory illness including asthma (n = 2131), and controls (n = 5703) were other emergency admissions excluding accidents. Cases and controls were compared with respect to distance of residence from nearest main road or roads with peak hour traffic >1000 vehicles and traffic volume within 150 m of residence, obtained by Geographical Information System techniques. Statistical analysis included adjustment for age, sex, admitting hospital, and a deprivation score for the census enumeration district of residence.?RESULTS—Adjusted odds ratios of hospital admission for asthma and respiratory illness for children living within 150 m of a main road compared with those living further away were, respectively, 0.93(95% CI 0.82 to 1.06) and 1.02 (95% CI 0.92 to 1.14).?CONCLUSIONS—This study showed no association between risk of hospital admission for asthma or respiratory illness among children aged 5-14 and proxy markers of road traffic pollution.??

[Fetal lesions due to the bistoury during cesarean section: a study of 58 cases. The 5-year case records of 3117 cesarean sections at the Institutes of Clinical Obstetrics and Gynecology of the University of Rome La Sapienza].  

PubMed

In the present article the authors have carried out a statistical investigation on data relative to the caesarean sections performed in the Departments of Obstetrics and Gynaecology of the University of Rome "La Sapienza" since 1986 to 1990. Particular object of this study is to evaluate data regarding fetal bistoury lesions incidentally caused while performing the incision of the uterine wall during a caesarean section. To our knowledge, this topic has never been taken into account by the world's literature, nevertheless it is important also for its legal and insurance implications. Throughout the mentioned period 13787 deliveries occurred, 3117 of which were caesarean sections: this is equal to a frequency of 22.6%, with an increase rate of 37.5% during the whole 5 years time. 58 cases of fetal bistoury lesions have been found to occur since 1986 to 1990: this equal to 1.8% of all the performed caesarean sections. Even if their gravity was usually scarce, and only 7 cases needed a specific treatment, 25.8% of these lesions involved areas such as forehead, cheek bone, cheek, mostly related to possible aesthetic damages with their connected legal consequences. In order to evaluate what factors can contribute to the occurrence of these lesions and taking account of the large number of factors that may be involved (such as conditions at which the operation is performed, skill and experience of the surgeon etc.), the authors focus their attention to those which, for their clinical significance and possibility of detection, suit more than others such a statistical investigation.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8559441

[Retroperitoneal neoformation: case study].  

PubMed

Retroperitoneal sarcoma represents approximately 12-15% of all sarcomas and between 0.2 and 0.5% of all neoplasia. They very rarely metastasize, and the main cause of death is local recurrence. Radiotherapy and chemotherapy still do not represent valid therapeutic alternatives, therefore radical surgery remains the only valid option. We would like to present the following case of a 48-year-old male patient. After episodes of right-side renal colic, a 19x16x19 cm mass was found, which was palpable in the right quadrants, englobed the right ureter and caused ipsilateral hydroureteronephrosis of medium grade. Surgery allowed total excision of this neoplasm (which was tenaciously attached to various organs), with the sacrifice of the right kidney. The final histological examination on a sample taken during surgery confirmed that the neoplasm was a spindle-cell sarcoma at an intermediate grade of malignancy. One year after surgery the patient is disease free. PMID:21948137

Changes in a top-level soccer referee's training, match activities, and physiology over an 8-year period: a case study.  

PubMed

Athlete case studies have often focused on the training outcome and not the training process. Consequently, there is a dearth of information detailing longitudinal training protocols, yet it is the combined assessment of both outcome and process that enhances the interpretation of physical test data. We were provided with a unique opportunity to assess the training load, physical match performance, and physiological fitness of an elite soccer referee from the referee's final season before attaining full-time, professional status (2002) until the season when he refereed the 2010 UEFA Champions League and FIFA World Cup finals. An increased focus on on-field speed and gym-based strength training was observed toward the end of the study period and longitudinal match data showed a tendency for decreased total distances but an increased intensity of movements. Laboratory assessments demonstrated that VO2max remained stable (52.3 vs 50.8 mL·kg-1·min-1), whereas running speed at the lactate threshold (14.0 vs 12.0 km·h-1) and running economy (37.3 vs 43.4 mL·kg-1·min-1) both improved in 2010 compared with 2002.

The effect of stocking with 0+ year age-class Atlantic salmon Salmo salar fry: a case study from the River Bush, Northern Ireland.  

PubMed

An enhancement programme based on stocking 0+ year age-class Atlantic salmon Salmo salar, conducted in the River Bush, Northern Ireland, U.K. over the period 1996-2005, was reviewed with reference to the performance and biological characteristics of wild fish. Wild ova to 0+ year fry (summer) survival was c. 8% with subsequent wild 0+ year fry-to-smolt survival c. 9%. Stocked unfed 0+ year juveniles gave c. 1% survival to smolt whilst fed 0+ year S. salar stocked in late summer exhibited survival at c. 5%. Stocking with unfed and fed fry contributed to increased smolt production and helped attain local management objectives between 2001 and 2005. Significant differences in biological characteristics were observed between wild and stocked-origin fish. Wild-smolt cohorts were dominated by 2+ year age-class fish on the River Bush whilst smolts originating from fed fry mostly comprised younger 1+ year individuals. The mean mass of 1+ year smolts derived from stocked fed fry was significantly lower than that of wild 1+ year smolts, although these differences were not evident between older age classes. Differences in run timing between wild smolts and smolts derived from stocked fry were also apparent with the stocked-origin fish tending to run earlier than wild fish. Although the stocking exercise was useful in terms of maximizing freshwater production, concerns over the quality of stocked-origin recruits and the long term consequences for productivity are highlighted.

PREDICT : A CASE STUDY.  

SciTech Connect

Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

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.

Tramadol induced seizure: A 3-year study  

PubMed Central

Background: Tramadol is a synthetic analgesic. Seizures have been reported in patients receiving this drug. In this study we evaluated the correlation between tramadol consumption and seizure occurrence. Methods: Twenty-eight subjects with a history of tramadol consumption and seizure were studied. Electroencephalograms (EEG) were performed in the first 24 hours and again one week later. Subjects were followed up for a mean of 18 months after the initial attack. Results: In the 28 subjects, 26 (92.8%) were males and 2 (7.2%) were females. The mean age of the subjects was 28.4 years. Thirteen patients had abused more than 400 mg/day of tramadol. Sixteen subjects concomitantly used other drugs. The seizures occurred within the first 24 hours of tramadol intake in 25 of the subjects. The first EEG was abnormal in 12 cases, but the second EEG was abnormal in only one case. Neuroimaging of only one subject displayed patchy white matter lesions. Conclusion: In conclusion, the neurotoxicity of tramadol commonly manifests as generalized tonic clonic seizures most frequently within 24 hours after tramadol intake and was more common in subjects concomitantly consuming alcohol, illicit drugs, anti-psychotics, or anti-depressants.

The First Case(s) of Botulism in Vienna in 21 Years: A Case Report  

PubMed Central

We describe two linked cases of botulinum toxin intoxication to provide the clinician with a better idea about how botulism cases may present since early diagnosis and treatment are crucial in botulism. Botulinum toxin is the strongest neurotoxin known. Methods: We review the available literature, the compiled clinical data, and observations. Results: After a slow onset of clinical signs a married couple living in Vienna presented with dysphagia, difficulties in accommodation, inability to sweat, urinary and stool retention, dizziness, and nausea. They suffered intoxication with botulinum toxin type B. Botulism is a rarely occurring disease in Austria. In the last 21 years there were only twelve reported cases. Conclusion: Both patients went to a general practitioner as well as several specialists before they were sent to and correctly diagnosed at our outpatient department. To avoid long delays between intoxication and diagnosis we think it is crucial to advert to the complex symptoms a nonsevere intoxication with botulinum toxin can produce, especially since intoxications have become rare occurrences in the industrialized societies due to the high quality of industrial food production.

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.

Calciphylaxis: a case study.

Caring for J.D. was a stressful experience. The extent of her wounds, pain, and limited options for treatment was very frustrating for the nursing staff. Although she did not survive, patient outcomes were met to some degree. Her pain was controlled to a greater extent, and there was less infection present in her wounds. The nurses worked with J.D. closely to improve her pain control and facilitate less painful dressing changes. They were vigilant in assessing the progress of her wound healing and communicating any increased signs of infections from her wounds. They sang with her to help distract her from the pain she was experiencing and to help her cope with her lengthy 8-month hospitalization. Providing care for J.D. was also a very important learning experience for nurses in terms of appropriate pain management for patients with CUA, wound care, and the need to sustain adequate nutrition to promote wound healing. CUA is a rare but potentially fatal disease that occurs in patients with end stage renal disease (ESRD). Early diagnosis and treatment are essential to prevent the devastating effects of this disease. Nephrology nurses need to reinforce the importance of keeping calcium, phosphorous, and parathyroid levels within normal ranges for their patients on dialysis. They also need to be vigilant in monitoring for potential CUA skin lesions to prevent and treat it early. To date, treatment options are mostly based on findings from case reports. Treatment requires a multidisciplinary approach with input from nephrologists, nurses, pain specialists, infectious disease specialists, and surgeons. The major goals of treatment are controlling risk factors, controlling pain, and preventing wound infection and possible sepsis. More studies need to be conducted to test interventions that may help treat CUA. PMID:23094342

Rheumatoid nodulosis. Two cases with destructive polyarthritis after 20 years.  

PubMed

The term "rheumatoid nodulosis" was coined by Ginsberg in 1975 to designate a rare and distinctive form of rheumatoid disease. Anecdotal case reports suggest a benign nondestructive course, although prolonged follow-up data are usually unavailable. We describe two cases of typical rheumatoid nodulosis with follow-ups exceeding 25 years. Onset occurred at 14 and 22 years of age, respectively. Both patients presented with palindromic rheumatism, positive tests for rheumatoid factors, negative tests for other biological markers, and normal radiographs. Multiple subcutaneous nodules developed after 4 and 6 years with palindromic flares, respectively. Functional impairments and disfigurement required several surgical procedures to remove nodules. Histology was typical for rheumatoid nodules. Neither patient responded to disease-modifying anti-rheumatic drugs (gold, antimalarials, and D-penicillamine). Treatment consisted of nonsteroidal anti-inflammatory drugs combined with prednisone as needed. After 20 and 22 years of follow-up, respectively, both patients had typical rheumatoid arthritis with deformities and radiological joint destruction. In conclusion, these two cases establish that rheumatoid nodulosis can occur as a presentation of rheumatoid arthritis with a potential for severe joint damage after many years. PMID:16377229

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.

Searching for fossil microbial biofilms on Mars: a case study using a 3.46 billion-year old example from the Pilbara in Australia  

NASA Astrophysics Data System (ADS)

With the immanent arrival of three Mars landers, one of which (Beagle 2) is dedicated to the search for life on Mars, analogue studies that are of general relevance to the search for past life on Mars are timely. We are using a 3.46 Ga, fossiliferous, sedimentary rock as a reference sample. The rock consists of laminated sediments, whose components were derived from volcanic rocks (volcaniclastic) that were deposited in a shallow water basin. Microbial mats occur at the surfaces of the sediments. This rock formed in an environment and from materials that would have existed on early Mars. Preliminary observation with the Beagle 2 camera shows that it should be possible to identify sedimentary structures, such as ripple marks and laminations, in fine detail. A 2 mm high ministromatolite/thrombolite layer was also readily visible. Further analysis using the microscope and the spectrometers would provide additional information that would lead to the choice of suitable samples, such as the ministromatolite/thrombolite layer, for chemical study with the gas analysis package. In this way details concerning the nature (and biogenicity) of the carbonaceous matter.

A matched case-control study of circumstances of occupational same-level falls and risk of wrist, ankle and hip fracture in women over 45 years of age.  

PubMed

This study examined the association between circumstances of occupational same-level falls and the risk of wrist, ankle and hip fracture in women over 45 years of age. Cases of fractures and matched controls who suffered non-fracture injuries, all from same-level falls, were selected from workers' compensation claims data. Cases and controls were matched on age, season of fall, industry and state. Information was obtained about manual material handling, fall hazard, initiating event and fall location. Falls during pushing/pulling were associated with increased wrist fracture risk. Falls due to tripping were associated with increased wrist fracture risk, but decreased risk of ankle fracture. Falling outdoors was associated with increased wrist and ankle fracture risk. Increasing age was associated with increased injury risk from tripping-initiated vs. slipping-initiated falls. Few circumstances increased risk of fracture at multiple sites, indicating that they affect risk of fracture by primarily affecting point of impact. The proportion of female workers over 45 years of age, who are at increased risk of fracture, is increasing in developed countries. This study examined the associations between circumstances of falls and wrist, ankle and hip fracture risks among these workers and found that the associations differed by fracture sites.

Therapeutic hypothermia: a case study.  

PubMed

Approximately 300,000 people experience sudden cardiac arrest (SCA) per year. The percentage of people who survive to discharge from the hospital is a dismal 10% to 25%. After SCA and the administration of cardiopulmonary resuscitation, these individuals can suffer what is known as "post resuscitation syndrome." This syndrome includes post-cardiac arrest brain injury, a cycle of cerebral edema and cell death that can lead to permanent neurological damage. In two landmark studies, therapeutic hypothermia (TH) was found to improve the chances of being discharged from the hospital post SCA by significant percentages. Despite endorsements, from the American Heart Association and other professional organizations, TH is not a well-known intervention. There are many reasons why this may be true. Despite its proven usefulness, TH does have some side effects that are best handled in the setting of intensive care units. This article describes a case of therapeutic hypothermia and its implications for perianesthesia nursing care. PMID:20511084

Lead poisoning: case studies.  

PubMed

Early clinical features of lead toxicity are non-specific and an occupational history is particularly valuable. Lead in the body comprises 2% in the blood (t1/2 35 days) and 95% in bone and dentine (t1/2 20-30 years). Blood lead may remain elevated for years after cessation from long exposure, due to redistribution from bone. Blood lead concentration is the most widely used marker for inorganic lead exposure. Zinc protoporphyrin (ZPP) concentration in blood usefully reflects lead exposure over the prior 3 months. Symptomatic patients with blood lead concentration >2.4 micromol l-1 (50 microg dl-1) or in any event >3.8 micromol l-1 (80 microg dl-1) should receive sodium calciumedetate i.v., followed by succimer by mouth for 19 days. Asymptomatic patients with blood lead concentration >2.4 micromol l-1 (50 microg dl-1) may be treated with succimer alone. Sodium calciumedetate should be given with dimercaprol to treat lead encephalopathy. PMID:11994050

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.

Case Studies in Science Ethics

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

Case studies: iron1234  

PubMed Central

Iron biomarkers were developed to define the size of iron stores and the adequacy of the iron supply required to meet functional needs. Approximately 80% of the iron delivered to tissues through the circulating plasma pool will be incorporated into hemoglobin. Consequently, with the exception of serum ferritin, iron biomarkers are measures of iron sufficiency for erythrocyte production. They have proven to be very valuable in the determination of the cause of anemia in the clinical setting in which additional information about factors that affect the patient's health is available. However, all current biomarkers are affected by factors other than iron status, which limit their utility for the determination of the prevalence of iron deficiency in some populations, particularly in populations who live in developing countries. Furthermore, relations between iron status and functional outcomes such as neonatal and infant mortality; motor, cognitive, and emotional development in infants; and severe morbidity from malaria in young children are inadequately characterized. There is a need to identify and standardize biomarkers that have the highest predictive value for specific functional outcomes in each setting. The most appropriate biomarkers may vary with the setting and be influenced by age, sex, gestational stage of pregnancy, and environmental factors such as repeated or chronic infections. There is also an urgent need for improved technology to permit the use of specific biomarkers in field studies in resource-poor regions. Finally, more research is required to define the potential role of hepcidin and non–transferrin-bound iron assays.

Thirty years of blackouts: a case report of swallow syncope.  

PubMed

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

Melanoma under 18 years and pregnancy: report of three cases.  

PubMed

Melanoma is an uncommon tumour in childhood. Only isolated cases in pregnant patients younger than 18 years old have been previously described, therefore the biological behaviour of cutaneous melanoma in this group of age remains largely unknown. We report a single-institution experience with three patients who developed cutaneous melanoma before the age of 18 years and became pregnant concomitantly or during the course of the disease. High tumour thickness was attributed to later diagnosis and could be responsible for the aggressive biological behaviour in these patients. This delay was in part due to patients considering changes in nevi to be normal during pregnancy. The effect of pregnancy on the prognosis of patients with melanoma, particularly the role of hormonal and immunological factors on clinical outcome, survival and risk of developing metastases, as well as the differences between adolescent and adult populations are still controversial. Since there are no specific treatment strategies for this group of patients, treatment recommendations should be established according to adult experience. PMID:20153997

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

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

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

Fluoxetine ingestion: a one year retrospective study.  

PubMed

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

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.

A 10-year retrospective study on odontogenic tumors in Iran.  

PubMed

Objective: The aim of this study was to review cases of odontogenic tumors diagnosed in two pathology centers in Tehran, Iran, during a 10-year period. Study Design: Patients' records were seen at two teaching pathology Centre's of Shahid Beheshti University between the months of March 2000 to 2010 with histologic diagnosis of any type of odontogenic tumors. The records were analyzed for frequency, age, sex, site, as well as clinical, radiographic and histopathologic findings. Results: Of 30706 biopsies, 4767 (15.5%) cases were diagnosed as oral and maxillofacial lesions. Among these, 720 cases were tumoral with 188 (26.1%) cases of odontogenic tumors. Tumors with odontogenic epithelium origin formed 70.2% of total numbers of odontogenic tumors. Mixed odontogenic tumors and tumors of odontogenic ectomesenchyme comprised 12.2% and 17.5% of the cases respectively. Ameloblastoma, with a frequency of 62.2% was the most common tumor in this review which was followed by odontoma and odontogenic myxoma. Conclusion: Although there are few studies on odontogenic tumors in literature, the comparison of our results with existing data shows significant differences in the distribution of tumors and age of patients, which may be due to ethnic features and geographic distribution of patients. Future studies on other ethnic groups are essential for further clarification of the findings in this research. PMID:23965450

[Asteroid hyalopathy. Ultrastructural study of 3 cases].  

PubMed

The vitreous of three patients with asteroďd hyalosis (average age: 57 years) was obtained by a two-hand closed pars plana vitrectomy. Asteroďd hyalosis was associated with alcoholic neuropathy in the first case, long standing retinal detachment in the second case, and diabetes mellitus in the third case. The visual acuity before and after the surgical procedure improved from 1.2/6 to 6/6 in the first case, from light perception to 0.3/6 in the second case, from 0.6/6 to 4.8/6 in the third case. The vitreous was studied by different ultrastructural technics : transmission electron microscopy (T.E.M.) scanning electron microscopy (S.E.M.) and electron diffraction X ray analysis (E.D.A.X.). By S.E.M. the asteroďd bodies appeared as rounded structures with an irregular surface connected to each other by fibrous strands among sodium chloride crystals. No cellular remnants were observed. By T.E.M. the asteroďd bodies were composed of interwinned ribbons of multilaminar membranes with a periodicity (10 to 60 A) characteristic of complex lipids, especially phospholipids. At the edge of the ribbons there were dots and sometimes clumps of opaque material that tended to crack out of the specimen with the heat of the electron beam. T.E.M. study disclosed the irregular disposition of the calcific bodies. By E.D.A.X. the calcific composition of the rounded structures could be determined : calcium and phosphorus were the main elements detectable in asteroďd bodies of all sizes for all three patients. The average calcium counts for the three successive cases were : 18, 30, 43 and for phosphorus : 9, 14, 26. Potassium was found in the first case, and sulfur in the third case.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6520332

Uterine carcinosarcomas: 8-year single center experience of 25 cases  

PubMed Central

Objectives: The aim of this retrospective study was to evaluate the behavior and treatment outcomes of uterine carcinosarcomas in relation to their clinical and pathogenic features and to determine the optimal treatment strategy. Secondary objectives were to identify parameters predictive of survival. Materials and Methods: The hospital records of all 25 patients of uterine carcinosarcoma operated between 2000 and 2008 in Gujarat cancer research institute, Ahmedabad, were reviewed. Patients who presented with clinical evidence of recurrent disease or those who had incomplete medical records were excluded from our analysis. The status of these patients was updated up to November, 2010. Patients were classified according to the new 2009 FIGO staging system for endometrial carcinoma, to see what difference the assigned stage has on survival with the old treatment strategy. Survival was calculated by Kaplan-Meier method and compared by Log-Rank test. Median survival time was derived with the Brookmeyer 95% confidence interval. For comparison of qualitative data, Chi-Square test and Fisher extract ?2 were used. Results: Median age of patients was 56 years (range, 36-77 years). Only 36% of patients had stage I at diagnosis and another 36% were stage III. Most of the tumors (56%) were with homologous sarcomatous components and 64% of tumors were high grade (grade 2/3) at diagnosis. Fifty-two percent patients received postoperative adjuvant treatment. Twelve patients had no postoperative treatment: two were lost to follow-up immediately after surgery, four could not receive adjuvant treatment on account of severe medical complications and age factor which could have increased morbidity, and six patients declined treatment. Four of these patients expired within one year of diagnosis, two other within 18 months, and rest were lost to follow-up. The difference in survival of 13 patients who had taken adjuvant treatment was significantly more than the group who had not taken adjuvant therapy (P=0.025). The overall 3-year disease-free survival of 13 patients who had taken adjuvant therapy was 40%. However, these adjuvant treatment modalities had borderline statistical significance on overall survival of patients (P=0.075). The only statistically significant predictor of survival in this study was stage of the disease (P=0.035). Conclusions: This highly aggressive uterine malignancy warrants comprehensive surgical staging to assess tumor dissemination followed by systematic adjuvant therapy in patients with both early and advanced disease. The value of pelvic Radiotherapy in addition to systemic treatment remains ill-defined. Stage is the significant predictor of survival for the disease. Our results indicate that in this highly aggressive malignancy, further exploration of potential outcome benefits of postoperative treatment, especially chemoradiation, is warranted in larger group of patients after comprehensive surgical staging.

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.

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

Anthrax outbreak in a Swedish beef cattle herd--1st case in 27 years: Case report.  

PubMed

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

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

PubMed

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. PMID:22509087

Women's gymnastics injuries. A 5-year study.  

PubMed

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

Socioeconomic Outcomes in Adults Malnourished in the First Year of Life: A 40-Year Study  

PubMed Central

OBJECTIVE: Lifelong functional, adaptive, and economic outcomes of moderate to severe infantile malnutrition are not well known. We assessed social status and income at midlife in a cohort of Barbadian adults, hospitalized for protein-energy malnutrition (PEM) during the first year of life, with good nutrition and health thereafter, in the context of a 40-year longitudinal case-control study. We also examined to what extent childhood IQ mediated any group differences. METHODS: Educational achievement, occupational status, and standard of living were assessed by the Hollingshead scales and a site-specific Ecology Questionnaire in Barbadian adults (aged 37–43 years) with a history of malnutrition (n = 80) and a matched healthy control group (n = 63), classmates of the index cases. Malnutrition effects, adjusted for childhood standard of living, were estimated by longitudinal multiple regression analyses, with and without childhood IQ, in the models. RESULTS: PEM predicted poorer socioeconomic outcomes with medium to large effect sizes (0.50–0.94), but childhood IQ substantially attenuated the magnitude of these effects (adjusted effect sizes: 0.17–0.34). The gap in weekly household income between the PEM and control groups increased substantially over the life span (P < .001). CONCLUSIONS: Moderate to severe PEM during the first year of life with adequate nutrition and health care thereafter is associated with significant depression of socioeconomic outcomes in adulthood, mediated in part by cognitive compromise in affected individuals. This finding underscores the potential long-term economic burden of infant malnutrition, which is of major concern given the continued high prevalence of malnutrition worldwide.

NWCC Transmission Case Study III  

SciTech Connect

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

[A 40 year old palatal neurofibroma. A case report].  

PubMed

Neurofibroma is a benign peripheral nerve sheath tumour, which arises from Schwann cells and perineural fibroblasts. It is one of the most frequent tumours of neural origin and its presence is one of the clinical criteria for the diagnosis of type 1 neurofibromatosis (NF-I) also known as von Recklinghausen's disease (VRD). Oral localization is rarer showing an incidence ranging from 4 to 7% in most series of different authors. The most frequent involvement site in oral neurofibromatosis is the tongue, followed by the oral mucosa and floor of the mouth; palate and maxillary-mandibular bones are a rare localization of the disease. The aim of this article is to report a case of NF-I with a huge, quite old palatal involvement and its treatment. PMID:23650755

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.

Minor burns due to fireworks which are treated in the Casualty Department have remained constant during the past ten years. The injured patients are boys and young men between 7-19 years. Boys are injured ten times as frequently as girls. The commonest sites of injuries are the upper limbs, the head and neck. The number of patients admitted to hospital on account of serious burns has increased. These are most frequently caused by clothes catching fire from fireworks which have been hidden under outer clothes or in trouser pockets. In order to avoid the serious burns caused by burning clothes, it is recommended that fireworks should not be concealed under clothes but carried away from the body possibly in a container made of non-inflammable material.

Prolonged Unilateral Disuse Osteopenia 14 Years Post External Fixator Removal: A Case History and Critical Review  

PubMed Central

Disuse osteopenia is a complication of immobilisation, with reversal generally noted upon remobilisation. This case report focuses on a patient who was seen 18 years following a road traffic collision when multiple fractures were sustained. The patient had an external fixator fitted for a tibia and fibula fracture, which remained in situ for a period of 4 years. Following removal, the patient was mobilised but, still required a single crutch to aid walking. Fourteen years post removal of the fixator, the patient had a DXA scan which, demonstrated a T-score 2.5 SD lower on the affected hip. This places the patient at an increased risk of hip fracture on this side, which requires monitoring. There appear to be no current studies investigating prolonged disuse-osteopenia in patients following removal of long-term external fixators. Further research is required to quantify unilateral long-term effects to bone health and fracture risk in this population.

Pesticide poisoning cases in Ankara and nearby cities in Turkey: an 11-year retrospective analysis.  

PubMed

Since they are available in open markets and pharmacies, pesticides have been widely used all over the country. (Un)intentional poisoning with these compounds is one of the most common causes of chemical poisoning, especially in rural agricultural areas. Pesticide poisonings reported by various countries showed that it is a worldwide health problem with 250,000-370,000 associated deaths each year. In this study, medico-legal deaths between the years 2001 and 2011 in Ankara and nearby cities in Turkey were investigated retrospectively. The autopsies were partly carried out by Ankara Branch of Council of Forensic Medicine. Data were collected from reports of the Morgue Department whose toxicological analyses were performed in the Chemistry Department. The data revealed that 70 cases out of 10,720 autopsied ones had been attributed to fatal pesticide poisoning. The age range was 1-80 years (mean ± SD, 41.33 ± 17.42 years). Most of the cases (60%) were reported from Ankara. Insecticides were the most common (94%) cause of fatal pesticide poisonings, most of them (63%) being organophosphate insecticides. The percentages of pesticide-induced deaths are quite high in our society and should therefore not be underestimated. Accordingly, intensive efforts to reduce occupational and intentional pesticide poisonings are urgently needed in Ankara and nearby cities. PMID:23622474

Traumatic intrusion of permanent teeth: 10 years follow-up of 2 cases.  

PubMed

Intrusive luxation is a kind of traumatic injury characterized by an axial displacement of the tooth toward the alveolar bone. Its main causes are bicycle accidents, sports/recreational activities, and falls or collisions. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning, and repositioning through dental traction by orthodontic devices. In order to decide which treatment to follow, the degree of root formation, the patient's age, and intrusion severity should be taken into consideration. This study aimed to report a 10-year follow-up of two patients that suffered permanent incisor (PI) traumatic injury who had a similar root development (incomplete rooting) but different results. In the first case, the treatment of choice was follow-up. The patient showed gingival alteration and root resorption of tooth 21. Calcium hydroxide therapy and root canal filling were performed twice because of not attending callback. After finishing the endodontic treatment, follow-up visits showed no abnormalities. In the second case, the treatment of choice was watch and wait to the teeth 11 and 21. After 7 months spontaneous eruption of both teeth was detected. Radiographic examination showed atypical root formation and almost completely pulp canal obliteration, 8 years later. In the follow-up, visit after 10 years was observed complete crow and pulp canal obliteration. It was concluded that PI intrusion treatments are good intervention alternatives, as they proved to be successful after a 10-year follow-up period. PMID:22251243

Case studies in Bayesian microbial risk assessments  

PubMed Central

Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs). Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5). The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11). In the second case study the effective number of inputs was reduced from 30 to 7 in the screening stage, and just 2 inputs were found to explain 82.8% of the output variance. A combined total of 500 runs of the computer code were used. Conclusion These case studies illustrate the use of Bayesian statistics to perform detailed uncertainty and sensitivity analyses, integrating multiple information sources in a way that is both rigorous and efficient.

Infantile meningitis in England and Wales: a two year study.  

PubMed Central

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

Bilateral ovarian teratoma complicated with carcinosarcoma in a 68 year old woman: a case report  

PubMed Central

Background Composing of less than 1% of all ovarian cancers, immature teratoma is a malignancy that mainly affects the young, and they present with advanced disease. The treatment of immature teratoma is conservative primary surgery usually involving unilateral salpingo-oophorectomy followed by combination chemotherapy. Case presentation Here we present a case of a 68 year old woman with bilateral ovarian teratoma complicated with carcinosarcoma. The patient was diagnosed as FIGO stage IIIC. She underwent neoadjuvant chemotherapy and interval cytoreduction followed by optimal cytoreduction. The post operative management strategies and gynaecological follow up studies revealed no evidence of regional or distant metastasis. Conclusion Thus the choice of initial treatment should be decided in a selective fashion depending on various prognostic factors in order to increase the survival of the patients.

[Overview of 40 years' chemical study].  

PubMed

1,6-Dihydro-3(2H)-pyridinone, designed as a common synthon for synthesis of various natural products, was found to be easily prepared in large scale and successfully used to synthesize a variety of alkaloids such as ibogamine, quinine and tecomanine. A tricyclo[3.3.0.0(2.8)]octane was also served as a common synthon for several sesquiterpenes such as pentalenene and quadrone. Synthetic studies by using sulfinyl chirality via an intramolecular Michael addition gave the novel route to construct spiro-ketal moiety in enantiomerically pure form. By applying this method, many natural spiro-ketal compounds were asymmetrically synthesized effectively. 3-Sulfinylated 1,4-dihydropyridine, a chiral NADH model compound, reduced activated ketones such as methyl benzoylformate to give the corresponding alcohols in excellent optical yields. A kind of 3-O-substituted pyridoxal chiral model compound was useful for preparation of alpha,alpha-dialkylated alpha-amino acids by asymmetric alpha-alkylation of alpha-amino acids. 2'-O,4'-C-Bridged nucleic acid analogs, BNAs, developed as novel type of artificial nucleic acids, showed an extraordinarily high binding affinity toward single stranded RNA and double stranded DNA complements along with excellent nuclease-resistant ability. Oligonucleotides containing BNA monomer units were proved to be very useful for various biotechnologies, such as antisense and antigene methodologies. PMID:19122440

Alaska placer mining metals study, year two  

SciTech Connect

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

Pyourachus: study of two cases.  

PubMed

The urachus, or median umbilical ligament, is a midline tubular structure that extends upward from the anterior dome of the bladder toward, the umbilicus and represents the vestigial remnant of at least two embryonic structures, the cloaca and the allantois. The tubular urachus normally involutes before birth, remaining as a fibrous band, however its persistence can give rise to various clinical problems, not only in infants and children but also in adults. We report two cases of pyourachus at our institute with a review of the clinical presentation, imaging findings and surgical management. Both our patients were young males, with haematuria being the presenting feature in one case which has not been previously described in literature. PMID:16823045

Diphyllobothriasis in a nine-year-old child in India: a case report  

PubMed Central

Introduction The Diphyllobothrium genus belongs to the Diphyllobothridea order of tapeworms. Diphyllobothrium spp., which is commonly known as fish tapeworm, is generally transmitted in humans, but also in other species, such as bears, dogs, cats, foxes, and other terrestrial carnivores. Although worldwide in distribution, the original heartland of Diphyllobothrium spp. spreads across Scandinavia, northern Russia, and western Serbia. We report a rare case that occurred in India. Case presentation A nine-year-old south Indian girl was brought to the casualty at the Prathima Institute of Medical Sciences with complaints of vomiting and loose stools that had started three days earlier. The vomit did not have a foul smell and contained no blood or mucus, but it did contain undigested food particles. The patient described a history of recurrent abdominal pain. She was a non-vegetarian and said she had a history of eating fish. Conclusion The incidence of Diphyllobothrium spp. infection is infrequent in India. Since this is only the fourth reported case in India, and since the previously reported cases also involved observed pediatric patients, we emphasize the need for clinical microbiologists and pediatricians to suspect fish tapeworm infection and recommend epidemiological study of Diphyllobothrium spp. infection.

A 10-year epidemiologic review of homicide cases in children younger than 5 years in Fulton County, GA: 1996-2005.  

PubMed

The primary purpose of this study was to present the epidemiologic review of homicide deaths certified by the Fulton County Medical Examiner's Office from January 1, 1996 through December 31, 2005 in children younger than 5 years. The secondary purpose of this study was to determine if the observed cases of homicide deaths among children younger than 5 years in Fulton County are significantly greater than expected when compared with those in the State of Georgia. For purposes of this study, only homicide deaths of Fulton County residents were included. The authors reviewed all homicide cases in children younger than 5 years: infancy (<1 year) and early childhood (1-4 years). ? values were calculated using Epi Info (version 3.4.1; Centers for Disease Control and Prevention, Atlanta, Ga) to determine differences in homicide among age group, race, and sex variables. In addition, a ? test at the ? level of 0.05 was done to determine if the observed cases of homicide deaths among children younger than 5 years in Fulton County were significantly greater than expected when compared with those in the State of Georgia. There were 49 homicide cases in children younger than 5 years identified over this 10-year period. The yearly distribution of these 49 homicide deaths ranged from 1 death in 2003 to 9 deaths in 2004. Most of the patients were male (n=29, 59.2%) and black (n=44, 89.8%). Between infancy and early childhood cases, homicide victims were nearly equally divided between the 2 groups. However, ? values showed that decedents younger than 5 years are more likely to have died of homicide compared with decedents 5 years or older (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.29-2.35). Black decedents younger than 5 years are more likely to have died of homicide compared with other races (OR, 3.21; 95% CI, 1.21-9.28). Male and female decedents are equally at risk to have died of homicide (OR, 1.14; 95% CI, 0.61-2.11). The authors also determined that the total homicide risk for children younger than 5 years in Fulton County during the years 1996 to 2005, at the ? level of 0.05, is 1.8 relative to the state. Brain injury was the primary cause of death in most cases (n=23, 46.9%). Although this study was unable to collect information on the victim's suspect/offender characteristics, it was noted that only 37% of the cases (n=18) went to trial. Most homicide investigations were under the Atlanta police jurisdiction (n=28, 57.1%). Results from this study may assist local and state government officials in recognizing the epidemiologic characteristics of children at risk to help them allocate limited resources efficiently and implement preventive measures to at-risk populations effectively.

Hospital acquired native valve endocarditis: analysis of 22 cases presenting over 11 years  

PubMed Central

Objective—To analyse hospital acquired infective endocarditis cases with respect to age, sex, clinical, laboratory, and echocardiographic features, predisposition, complications, surgery, mortality, and diagnostic criteria.?Design—Prospective cohort study.?Setting—Teaching hospital.?Patients—A series of 200 patients with infective endocarditis presenting over 11 years, 168 with native valve infective endocarditis, of whom 22 acquired this infection in hospital.?Results—22 (14%) of the 168 cases of native valve infection were hospital acquired. The most common pathogens were staphylococci (77%). Two thirds of patients had no cardiac predisposition; one third had end stage renal disease. The most common source of infection was vascular access sites (73%). Eleven patients died. In 11 cases, infective endocarditis was proven pathologically (six at necropsy, five during surgery) and analysis of these showed that 45% were classed as probable by the Beth Israel criteria, 73% as definite by the Duke criteria, and 91% as definite by our suggested modifications of the Duke criteria. Figures for the 11 cases not proven pathologically were 27%, 73%, and 91%, respectively. Five of the 22 cases (22%) were rejected by the Beth Israel criteria but none were rejected by the Duke criteria with or without our modifications.?Conclusions—Hospital acquired infective endocarditis is difficult to diagnose. The Duke criteria have improved diagnostic sensitivity and our modifications have improved it further. Mortality is high but has been reduced by surgery. This serious infection could, in many cases, be prevented by improved care of intravascular lines and prompt removal when obviously infected.??

The abundance and diversity of legume-nodulating rhizobia in 28-year-old plantations of tropical, subtropical, and exotic tree species: a case study from the Forest Reserve of Bandia, Senegal.  

PubMed

Several fast-growing and multipurpose tree species have been widely used in West Africa to both reverse the tendency of land degradation and restore soil productivity. Although beneficial effects have been reported on soil stabilization, there still remains a lack of information about their impact on soil microorganisms. Our investigation has been carried out in exotic and native tree plantations of 28 years and aimed to survey and compare the abundance and genetic diversity of natural legume-nodulating rhizobia (LNR). The study of LNR is supported by the phylogenetic analysis which clustered the isolates into three genera: Bradyrhizobium, Mesorhizobium, and Sinorhizobium. The results showed close positive correlations between the sizes of LNR populations estimated both in the dry and rainy seasons and the presence of legume tree hosts. There were significant increases in Rhizobium spp. population densities in response to planting with Acacia spp., and high genetic diversities and richness of genotypes were fittest in these tree plantations. This suggests that enrichment of soil Rhizobium spp. populations is host specific. The results indicated also that species of genera Mesorhizobium and Sinorhizobium were lacking in plantations of non-host species. By contrast, there was a widespread distribution of Bradyrhizobium spp. strains across the tree plantations, with no evident specialization in regard to plantation type. Finally, the study provides information about the LNR communities associated with a range of old tree plantations and some aspects of their relationships to soil factors, which may facilitate the management of man-made forest systems that target ecosystem rehabilitation and preservation of soil biota.

Freak Waves: A case study  

NASA Astrophysics Data System (ADS)

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