    2002-01-01

    Full Text Available Macular amyloidosis is an important cause for cutaneous pigmentation, the aetiology of which is poorly understood. Friction has recently been implicated the causation of early lesions, referred to as frictional amyloidosis. Confirmation of diagnosis by the detect on of amyloid using histochemical stains is inconsistent. Ten patients with pigmentation suggestive of macular amyloidosis were studied with detailed history, clinical examination, biopsy for histochemistry and electron microscopy. Nine out of ten patients had a history of prolonged friction with various objects such as bath sponges, brushes, towels, plant sticks and leaves. Amyloid was demonstrated by histochemical staining in only six out of ten cases. In the remaining four cases, amyloid was detected by electron microscopy. These consisted of aggregates of non-branching, extracellular, intertwining fibres measuring between 200-500 nm in length and between 20-25 nm in diameter. The study confirms the role of friction in the causation of this condition. Histochemical stains are not always successful in the detection of amyloid and electron microscopy is helpful for confirming its presence. The term frictional amyloidosis aptly describes the condition.

    2008-07-01

    This study describes ten cases of filicides committed by mothers who intentionally killed one or more of their children within 12 months after delivery. The data were collected from police and court records, forensic psychiatric records, autopsy reports, and other medical records. The mean age of the mothers was 28.5 years and of the victims 4 months. The symptoms of depression were clear: an irritable, severely depressed mood with crying spells, insomnia, fatigue, anxiety, preoccupation with worries about the baby's well-being and the mother's caring abilities, suicidal ideation, or even psychotic thoughts. Most mothers had had house calls from the public health nurse or psychologist. The mothers' conditions deteriorated rapidly, and the filicide was committed when the mother was left alone with the baby against her will. The babies were well taken care of, not neglected or abused. The majority of the mothers had felt that their own parents, especially their mothers, were very demanding, rejecting, and emotionally unsupportive. All the mothers had also had traumatic experiences in their childhood or in adulthood. PMID:18587626

    1993-11-01

    In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

  7. The acute radiation syndrome: A study of ten cases and a review of the problem

    Hempelmann, L.H.; Lisco, H.

    1950-03-17

    In this report ten cases of acute radiation syndrome are described resulting from two accidents occurring at the Los Alamos Scientific Laboratory of unique nature involving fissionable material. These cases are described in considerable detail. The report comprises ten sections. This volume, part II of the report, is comprised of sections entitled: (1) the Biological Basis for the Clinical Response seen in the Acute radiation Syndrome, (2) Clinical Signs and Symptoms, (3) Discussion of Hematological Findings, (4) Chemistry of the Blood and Urine, (5) Discussion of Pathological Findings, and (6) Reconsiderations of the Calculated Radiation Doses in Terms of the Observed Biological Response of the Patients. This report was prepared primarily for the clinician who is interested in radiation injuries and therefore emphasis has been placed on the correlation of clinical and pathological changes with the type of cytogenetic change known to be produced by ionizing radiation.

  8. Making a difference: Ten case studies of DSM/IRP interactive efforts and related advocacy group activities

    English, M.; Schexnayder, S.; Altman, J. [Tennessee Univ., Knoxville, TN (United States). Energy, Environment and Resources Center; Schweitzer, M. [Oak Ridge National Lab., TN (United States)

    1994-03-01

    This report discusses the activities of organizations that seek to promote integrated resource planning and aggressive, cost-effective demand-side management by utilities. The activities of such groups -- here called energy efficiency advocacy groups (EEAGs) -- are examined in ten detailed am studies. Nine of the cases involve some form of interactive effort between investor-owned electric utilities and non-utility to develop policies, plans, or programs cooperatively. Many but not all of the interactive efforts examined are formal collaboratives. In addition, all ten cases include discussion of other EEAG activities, such as coalition-building, research, participation in statewide energy planning, and intervention in regulatory proceedings.

    The aim of this study was to determine whether the cognitive impairment is associated with corpus callosum infarctions. Ten corpus callosum infarction patients were enrolled in this study. Their emotions, cognitive and language abilities, memory, comprehensive perception were assessed using the Chinese version of following measures: Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), World Health Organization-University of California-Los Angeles Auditory Verbal Learning Test (WHO-UCLA AVLT), Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest and so on. The same measurements were performed on healthy control participants as contrast for analysis. Infarction most frequently occurred in the body and/or splenium of the corpus callosum. The scores of the most cognitive tests in the corpus callosum infarction patients were significantly worse than those of the control participants (Pability, the patients showed significantly poorer performance at the overall level of MMSE than the controls did (Pabilities of execution, orientation, attention, calculation, delayed memory, language, and repetition capabilities in the patients with respect to the control (Pabilities, attention and calculating abilities.

  11. A clinical study on ten cases of superior mesenteric arterial occulusion

    A total of 10 cases of acute superior mesenteric arterial occulusion (SMAO) treated in our department in a previous 11-year period were divided into the survival (n=4) and death (n=6) groups and studied for the diagnosis, treatment, and postoperative management. An averaged age of them was as high as 81 years. All the patients had some cardiovascular disorders as underlying diseases, and seven patients of them had atrial fibrillation. The time from the onset of SMAO to the treatment ranged from 4 to 96 hours, in that no significant difference was noted between the survival and death groups. Contrast enhanced abdominal CT was conducted preoperatively in all the patients. It was retrospectively considered that preoperative diagnosis had to be made by the CT scans in eight of them who had developed occulusion at the center of the superior mesenteric artery. Except one patient who could be treated by interventional radiology (IVR) using a balloon-tip catheter, the remaining nine patients underwent laparotomy and six out of the nine patients underwent the resection of massive intestines. Seven patients overcame postoperative acute phase, however, only four of them were able to recover their social activities. In order to improve the prognosis of the disease, we are required not only to avoid massive intestinal resection by making early diagnosis, but also to conduct long-term postoperative intensive therapies including those for underlying diseases as well as prevention of recurrence and nutritional management.

  13. Lifeline electric rates and alternative approaches to the problems of low-income ratepayers: ten case studies of rejected programs

    1980-07-01

    This volume, Volume 3, contains ten case studies of non-implemented programs. It is noted that in Volume 2, the implemented lifeline programs, evolved as policy closely after the 1973 oil embargo; in contrast, the rejected programs were initiated about 4 years later and considered in a more-complex policy environment - after which time alternate methods of assisting low-income people had been developed. Specifically presented here are program summary, issue development, governmental process, and impact for the following: (a) Delaware Senate Bill 202; (b) Illinois House Bill 83; (c) Maine Legislative Document No. 1043; (d) Minnesota House File 1243; (e) New York Assembly Bill 12214; (f) New York Senate Bill 7013-A; (g) Rhode Island Resolution 79-H 5770-A; (h) South Dakota Senate Joint Resolution 9; (i) West Virginia House Bill 943; and (j) Wisconsin Assembly Bill 1250. 4 figures, 24 tables.

    2003-01-01

    An impressive decline in leprosy prevalence rate (PR) in all endemic districts of India is seen in the post-MDT era. However, the new case-detection rate, an important statistical indicator in leprosy control programmes, has not shown significant decline in spite of all efforts. In Himachal Pradesh, a decline in PR from 7.8 to 0.56/10000 between 1991 to 2000 is seen, and recently the State has won national acclaim for having achieved the goal of elimination of leprosy in all the districts. The vertical leprosy programme has been integrated into general health services of the state. An analysis of data from 1991 to 2000 of two leprosy control units of Himachal Pradesh, the Urban Leprosy Clinic in Shimla (ULC-S) and the District Leprosy Control Unit in Mandi (DLCU-M), showed no significant decline in the new cases detected. 277 and 271 new cases were detected at these centres respectively; these included 2.2% and 1.5% children of less than 14 years of age. Almost 75% of these cases were males and of MB type. A steadily increasing trend in the annual detection of new cases was seen at both the centres during the decade. The cases registered at DLCU-M were mainly indigenous to the district. At ULC-S, 45 migrant cases from other endemic areas-mainly from Nepal, Bihar, and Uttar Pradesh-had also contributed to the increased number of new cases. Other possible causes discussed for this higher new case detection, e.g. overdiagnosis, detection of backlog "hidden cases" and voluntary reporting of patients, do not differ from those seen in other parts of the country or the world.

  16. Amoxicillin induced toxic epidermal necrolysis (TEN: a case report

    Jaimin B. Patel

    2015-04-01

    Full Text Available Each year many patients are hospitalized due to adverse drug reactions. Adverse reactions are the recognized hazards of drug therapy and they can occur with any class of drugs and many studies revealed that the incidence is more in case of antibiotics. Amoxicillin is a broad spectrum, bactericidal, beta lactam antibiotic, commonly used to combat various infections. Penicillin group of drugs are known to cause cutaneous drug eruptions especially in pediatric population. Most of the time, these eruptions are mild in nature, however, sometimes they represent the early manifestation of rare, severe drug-induced cutaneous reactions, such as Stevens-Johnson Syndrome (SJS and Toxic Epidermal Necrolysis (TEN. Toxic Epidermal Necrolysis (TEN is a rare, life threatening dermatological disorder that is usually induced by medications. Seventy percent of the cases of TEN are drug induced, most commonly implicated drugs being anticonvulsants, antibiotics and Non-Steroidal Anti-Inflammatory Drugs (NSAIDS. Here, we report a case of toxic epidermal necrolysis induced by amoxicillin in a 16 year old female patient. Rigorous treatment with systemic corticosteroids and immunoglobulins helped in recovery of the patient. The case is being reported to emphasize the need for efficient pharmacovigilance in order to motivate adverse drug reaction reporting so as to gather more and more data regarding adverse drug reactions. Through this report, we also seek the support of everyone concerned to detect and, if possible, prevent adverse reactions to drugs. [Int J Res Med Sci 2015; 3(4.000: 1011-1014

  18. Breast Cancer in Transgender Veterans: A Ten-Case Series.

    Brown, George R

    2015-03-01

    All known cases of breast cancer in patients with a diagnosis consistent with transgender identification were identified in the Veterans Health Administration (1996-2013). Ten cases were confirmed: seven birth sex females and three birth sex males. Of the three birth sex males, two identified as gender dysphoric male-to-female and one identified as transgender with transvestic fetishism. The birth sex males all presented with late-stage disease that proved fatal, whereas most of the birth sex female transgender veterans presented with earlier stage disease that could be treated. These cases support the importance of screening for breast cancer using standard guidelines in birth sex males and females. Family history of breast cancer should be obtained from transgender people as part of routine care. This report expands the known cases of breast cancer in transgender persons from 5 to 12 (female-to-male) and from 10 to 13 (male-to-female). PMID:26790021

    Objective To investigate the clinical features and management ofureteral endometriosis.Methods Patients surgically and histologically diagnosed as ureteral endometriosis from January 2001 to January 2007 in Peking Union Medical College Hospital were retrospectively reviewed.Results Ten patients were diagnosed as ureteral endometriosis among 7561 cases with surgically and histologically proved diagnosis of endometriosis,with an incidence of 0.132%.Nine out of 10 patients were extrinsic ureteral endometriosis and concomitant with severe pelvic endometriosis,and the other was intrinsic ureteral endometriosis.Hormone therapy failed in 2 patients with urinary tract obstruction.Ureterolysis was performed in 6 patients and ureterectomy was performed in 4 patients.One ease of ureteral recurrence was observed in a postmenopausal woman without hormonal replacement therapy who received laparoscopic ureterolysis and hysterectomy with bilateral adnexectomy.No relapse was observed in the other 9 patients.Conclusions Ureteral endometriosis is a rare entity.The upper urinary tract should be evaluated in patients with severe endometriosis,even in postmenopausal women.The treatment of ureteral endometriosis usually requires surgery,while ureterolysis should not be performed in patients with extensive disease.As a form of adjuvant therapy of surgery,hormonal therapy is an appropriate option.

  20. Lessons learnt from ten performance assessment studies

    The management of radioactive wastes and, in particular, the safety assessment of radioactive waste disposal systems are areas of high priority in the programme of the OECD Nuclear Energy Agency (NEA). In 1994, a Working Group was set up under the PAAG (Performance Assessment Advisory Group) on Integrated Performance Assessments of Deep Repositories (IPAG). The aim of the group is to provide a forum for informed discussion on performance assessment (PA), and to examine the overall status of PA and specific issues identified by the group and the PAAG. This document presents the report of a first phase of work completed in December 1996 and is expected to be of most interest to practitioners of repository PA and those with an interest in technical review of PA studies.

    Full Text Available Fuel market is facing political, economic, social and environmental problems that are fuzzing the future of fossil energy sources and in face of these facts, countries are looking for hybrid and electric vehicles as part of solution in transportation sector due to the fact of electric vehicles use few or no fossil fuel. The objective in this article was to identify options until 2020 to introduce electric vehicle in the urban traffic of São Paulo city and to develop this study the method of literature review in secondary sources was used to present electric vehicle technologies and to identify parameters that were assessed through morphological analysis technique. In morphological analysis, sets of values were defined by the author for these parameters, possible combinations were structured, clearly impractical deployment options before 2020 were discarded and some viable solutions were analyzed in details. These analyses concluded that there are viable options for actual days in São Paulo city, but important requirements regarding technology, politic, market, infrastructure and innovation in products and services still need to be addressed and it is the main reason of electric vehicle remain unnoticed by consumers as an viable option. The challenges are great and the actors who are willing to solve them will find a promising market to explore.

    2003-01-01

    Objective: To gain further understanding of the antiphospholipid syndrome(APS). Methods: Analysing clinical and laboratory data on ten cases of APS. Results: Thrombocytopenia appeared in all cases. Venous thrombi of limbs appeared in five cases and neurological abnormalities in two cases. Renal impairments were found in three cases. One case manifested left renal venous thrombi and the other two cases thrombotic microangiopathy. Budd-Chiari syndrome was found in one case. One of the ten cases was catastrophic APS(CAPS) presented as acute diffuse swelling, cyanosis, pain, ischemia and necrosis in fingers and limbs, recurrent shock, ascites, hepatic and respiratory dysfunction. Anticoagulants and corticosteroids could be effective for dealing with APS. It was critical to treat catastrophic APS with anticoagulants or plasmapheresis as early as possible. Conclusions: APS shows variable manifestations for good prognosis, but catastrophic APS has fatal risk. The main treatment for APS is the use of anticoagulants and immunosuppressives.

    2004-11-01

    The aim of this study is to report the typical radiographic and MR imaging features of calcific myonecrosis, which help to distinguish this rare entity from other causes of a calcifying calf mass. Ten patients with a final diagnosis of calcific myonecrosis were referred to a specialist orthopaedic oncology service in a 5-year period with the presumptive diagnosis of malignancy based on recent clinical presentation and imaging findings. Radiographs were available for retrospective review in all ten cases and MR imaging in six. All patients presented with a slow-growing painless calf mass. All gave a history of major trauma to the lower leg many years before, but in only two cases did the referring clinician query whether trauma might be a contributory factor. Radiographs showed well-defined fusiform mineralised masses up to 25 cm in length arising within the calf. The calcification was consistently peripheral and plaque-like. Ossification was not present. MR imaging showed the anterior compartment to be involved in four cases and all compartments in two. T1- and T2-weighted images showed peripheral low signal intensity, more prominent on the T2-weighted images, because of the peripheral mineralization. The contents of the masses were variable on T1-weighted images depending on the differing amounts of blood breakdown products and were heterogeneous on T2-weighted images. The latter may be explained by a combination of the mineralisation and T2 shortening due to blood breakdown products. A gadolinium chelate, administered in two cases, failed to show any appreciable enhancement. Calcific myonecrosis has characteristic clinical, radiographic and MR features that should make the condition easy to recognise. Despite its rarity, it should be included in the differential diagnosis of focal mineralisation of the calf. (orig.)

    Full Text Available Abstract Primary lymphoma is an uncommon malignancy of the thyroid, comprising of 0.6 to 5 per cent of thyroid cancers in most series. Primary thyroid lymphomas (PTL occur most commonly in elderly women and are commonly of B- cell origin. These frequently present in clinical stage IE and IIE. We report here ten cases of PTL diagnosed over a period of about 7 years in our institute. Out of these ten cases, nine were diagnosed on fine needle aspiration cytology (FNAC and one case was misdiagnosed as lymphocytic thyroiditis. This case was diagnosed as Non- Hodgkin's lymphoma on surgical specimen. Five patients are disease free and doing well, while two died of disease and the other two were lost to follow-up. One patient is currently on chemotherapy. The salient clinical, biochemical, radiological features, FNA findings along with diagnostic difficulties are discussed.

  13. Use of interactive lecture demonstrations: A ten year study

    Ronald Thornton

    2010-10-01

    Full Text Available The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, the Interactive Lecture Demonstration (ILD is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80%. This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%. This paper also reports on teacher experiences of using the ILDs, in Project 2.

  17. Ganglion cysts at the gastrocnemius origin: a series of ten cases

    To describe ganglion cysts arising close to the origin of the medial and lateral head of gastrocnemius as identified on magnetic resonance (MR) imaging. We present a series of ten cases of ganglion cysts arising close to the gastrocnemius origin from the medial and lateral femoral condyles. These were collected over a 6-year period from our imaging database. All patients attended for routine MR imaging of the knee with a variety of clinical presentations. Data collected included patient demographics, ganglion size, ganglion site, clinical presentation and ancillary MR imaging findings. The ten patients in this series consisted of seven males and three females, five right and five left knees, age range 27-68 years, mean age 40.6 years. The mean maximal dimension of the ganglion cysts was 26 mm, range 15-40 mm. The medial gastrocnemius origin was involved in eight patients and the lateral origin in two patients. The MR imaging findings consisted of both uni- and multi-loculated cysts, often containing numerous septations with fluid signal characteristics. The cysts were extra-capsular with no clear communication with the joint. One patient presented with a popliteal soft tissue mass and none of the cases required surgical intervention for cyst removal. MR imaging may identify ganglion cysts arising in an intra- or extra-articular site around the knee. This series documents the MR imaging characteristics of ganglion cysts arising close to the gastrocnemius origin and discusses the relevance of this imaging finding. (orig.)

    Full Text Available Background: Gestational trophoblastic disease (GTD defines a heterogenenous group ofinterrelated lesions that arise from the trophoblastic epithelium of the placenta. There are severalhistologically distinct types of GTD: hydatiform mole (complete or partial, persistant/invasivegestational trophoblastic neoplasia (GTN, choriocarcinoma and placenta site trophoblastictumors. The aim of this study was to determine the frequency and risk factors of GTD amongwomen admitted to Imam Khomeini Hospital in Ahvaz, Iran.Materials and Methods: This was a cross-sectional study conducted at Imam KhomeiniHospital in Ahvaz, Iran. All hospital records related to GTD (132 from 1996 until 2006 werereviewed. Demographic and histo-pathologic characteristics were extracted. Chi-square andFisher-exact tests were used to analyze all variables. P ≤ 0.05 was considered statisticallysignificant. SPSS, version 11 was used for statistical analysis.Results: The mean age of patients was 27.6 years. Most patients who presented with GTDwere of ages 18-35 years (71.3%. There was no relationship between age and hydatiformmole during the reproductive years. There were 28 (18.9% patients over the age 40, of which18 (15.90% of these had a complete hydatiform mole. Within this group, 9 (6.8% changedto a persistent mole. There was a significant relationship between age over 40 and completemole (p<0.02. The percentage of patients with blood groups A and O was the same (37.9%.There was a significant relationship between blood groups (O+ and A+ and complete mole(p<0.05.Conclusion: The most common age range for hydatiform mole was 18-35 years. Women overthe age of 40 had a more complete hydatiform mole, which is similar to the other countries.Age and blood group are two risk factors for hydatiform mole.

    Full Text Available Background: Acute lymphoblastic leukemia (ALL is the most common cancer in the pediatric population. With modern treatments, the chance of the complete recovery is nearly 100%. The most important prognostic factors are appropriate treatment protocol and determination of patient risk factors based on clinical, morphological, immunological and cytological characteristics. In this study we reviewed frequency of these factors, like as age, gender, the primary white blood cell number, sub- group on the base of FAB classification, immunophenotype and the clinical progress. Methods: In this retrospective study, we reviewed 877 pediatric patients with the diagnosis of ALL between the years of 1994 and 2004. In these patients the age, gender, primary WBC count, sub-group based on the FAB classification, immunophenotype and the clinical progress in 177 patient with acute lymphoblastic leukemia at Imam Khomeini Hospital between the years of 1994 to 2004 were determined. Results: Of these patients, 1.6% was younger than one year, 24.8% more than ten years old and 73.6% were between the ages of one and ten years; 63.8% were male. WBC counts were above 50,000/ul in 28.8% of the patients. FAB classifications included L1 in 80.2%, L2 in 17.5% and L3 in 2.3% of the patients. Immunophenotypes included pre-B cell in 63.8%, early pre-B cell in 23.1%, T cell in 12.3% and mature B cell in 0.8% of the patients. Marker CD10+ was detected in 88.1% of the B cell cases. In this study group, 74% of the patients recovered, 16.3% died and 16.5% relapsed.Conclusions: The prevalence of FAB-L1 and pre-B cell cases in this study is greater than a previous study, while the prevalence of FAB-L2 and early pre-B cell cases is less than that of the previous study.

  3. A ten-year study of tick biting in Mississippi: implications for human disease transmission.

    Goddard, Jerome

    2002-01-01

    To determine exactly which tick species bit people in Mississippi, information was gathered on ticks involved in human biting cases for the ten-year period, January 1, 1990-December 31, 1999. Specimens were identified by the author and, in most cases, confirmed by personnel at the Institute of Arthropodology and Parasitology, Georgia Southern University. A total of 119 ticks were recovered from 73 humans during the study period. Seven tick species were represented; most common included the lone star tick, Amblyomma americanum, the gulf coast tick, A. maculatum, the American dog tick, Dermacentor variabilis, and the black-legged deer tick, Ixodes scapularis. Interestingly, no immature Ixodes scapularis were collected. there were several unusual records. Twelve larvae of Amblyomma tuberculatum, a species associated with the gopher tortoise, were removed from a patient. Two Dermacentor albipictus larvae were collected from an elderly woman with no travel history except her backyard. One Dermacentor sp. nymph, removed from a man in central MS, was not even a North American species. One adult female Dermacentor variabilis was involved in a clinical case of tick paralysis. These findings indicate that, although we know which tick species are common human biters, unusual/unreported tick-human interactions may be more common than we think. PMID:12853269

    Low back pain, caused by lumbar disc herniation, is prevalently treated with a conservative approach. In this study we valued the efficacy of High Intensity Laser Therapy (HILT), compared with accepted therapies such as TENS and NSAIDs. Laser therapy obtained similar results in the short term, but better clinical effect over time than TENS and NSAIDs. In conclusion high intensity laser therapy appears to be a interesting new treatment, worthy of further research.

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) induced by drugs are severe cutaneous adverse reactions, characterized by extensive detachment of epidermis and erosion of mucous membranes. In addition to the long term adopted Naranjo score to assess the causality of adverse drug reactions, ALDEN score derived from two large-scale case-control study also proved to be a useful assessment tool to evaluate the causality of drug-induced epidermal necrolysis recently. We described ALDEN score in detail and compared the assessment results of both tools applied through a real TEN case resulted in coadministrating acetaminophen and cefradine in this paper, and discussed the differentiation and suitability of two scores.%药物引起的史蒂文斯-约翰逊综合征(SJS)和中毒性表皮坏死松解症(TEN)是一种罕见严重的不良反应,其特征是广泛性的皮肤表皮剥离和黏膜侵犯。当评估可疑药物和SJS或TEN之间的因果关系时,除了Naranjo评分外,最近根据两个大型的病例对照研究结果所衍生的ALDEN评分也提供了新思路。本文结合1例同时服用对乙酰氨基酚和头孢拉定导致中毒性表皮坏死综合征的案例,应用ALDEN评分及Naranjo评分分析两种药物与ADR间的关联性,并讨论此两种评分方法的差异性及适宜性。

    1997-10-01

    MRI of ten atypical MCT were reviewed correlating with pathology and to clarify why they did not include any hyperintense area on T1-weighted images (T1WI). Nine of the ten cases had a few sebaceous glands. Intra-tumoral chemical shift artifact was noted in four and the presence of the finding was diagnostic of the disease. Two with abundant thyroid tissue showed multilocular cyst whose fluid in some loculi indicated hyperintense on T1WI and hypointense on T2WI, which was similar to MR findings of struma ovarii. Four with complication such as hemorrhagic necrosis demonstrated inhomogeneous signals and they were hardly diagnosed correctly. (author)

    Full Text Available Background: Primary dysmenorrhea is a common disabilitating factor in most of the adolescent girls. It is a major cause of inability to concentrate on their work or studies, class or school absenteeism, inability to perform in their academic activities. This study conducted to assess the effect of non-invasive treatments for pain relief during dysmenorrhea. Aim and Objectives: To study the effect of Conventional TENS and Spinal mobilization on pain in Primary Dysmenorrhea in adolescent girls. Materials and Methods: Fifty adolescent girls aged between 14-18 years were selected for the study that fulfilled the inclusion criteria. Quasi experimental study was done to compare the effect of TENS and Maitland’s spinal mobilisation in Adolscent girls suffering from primary dysmenorrhea. They were randomly divided in two groups: Group A for TENS (n= 24 and Group B for spinal mobilisation (n= 26 and participant’s menstrual history was recorded. Girls with severe dysmenorrhea, pelvic pathology and spinal pathology were excluded from this study. Treatment was given on 1st and 2nd day of menstruation period. Adolescent girls marked the Short form Mc gill Pain Questionnaire (SFMPQ which includes PPI and VAS before and just after the treatment. Total scores were noted and subjected to statistical analysis. Result: Data was analyzed using Mann Whitney U test which compared data between groups; results were not statistically significant (p> 0.05 for SFMPQ, PPI and VAS. Pain relief was approximately the same for the two groups. Conclusion: The study concludes that TENS and mobilisation both are effective reducing pain among adolescent girls who suffer from primary dysmenorrhea.

Most of authors believe it is a mixture of indigo (blue and indirubin (red that becomes purple. Previous study showed that PUBS occurred predominantly in chronically catheterized, constipated women. We collected 10 elderly patients with PUBS in two nursing homes. The first two cases were identified by chart review in 1987 and 2003, and then later eight cases (42.1% were collected among 19 urinary catheterized elderly in the period between January 2007 and June 2007. In the present report, PUBS probably can occur in any patients with the right elements, namely urinary tract infection (UTI with bacteria possessing these enzymes, diet with enough tryptophan, and being catheterized. Associations with bed-bound state, Alzheimer’s, or dementia from other causes are reflections of the state of such patients who are at higher risk for UTI, and hence PUBS occurred. Although we presented PUBS as a harmless problem, prevention and control of the nosocomial catheter-associated UTIs (CAUTIs has become very important in the new patient-centered medical era. Thus, we should decrease the duration of catheterization, improve catheter care, and deploy technological advances designed for prevention, especially in the elderly cared for in nursing homes.Keyword: purple urine bag syndrome, indigo, indirubin, nursing home, bacteriuria, indoxyl sulphatase

  16. Mucinous carcinoid of the ovary: report of a case with metastasis in the contralateral ovary after ten years

    Patricia C. Ewing

    2010-09-01

    Full Text Available Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

  19. Geomagnetic response to solar activity: summary for the last ten years and analysis of selected cases

    Hejda, Pavel; Bochníček, Josef; Valach, Fridrich; Revallo, Miloš

    2014-05-01

    The main sources of geomagnetic disturbances are either coronal mass ejections (CMEs), which are usually connected with eruptive flares, or high-speed streams of solar wind from coronal holes. Development of an eruptive flare and ejection of coronal mass is accompanied by magnetic reconnection. The evidence of reconnection can be found in a broad spectrum of observations. The observations of X-rays and radio bursts were used in our study. The geoeffectiveness of solar X-ray flares was initially analysed on data from the period 1996 - 2004 [1]. It was shown that the probability of geomagnetic response depends on the solar flare class and its position on the solar disc. The flares in the central region were found to be more geoeffective. The probability further increased if the flare was accompanied by Type II and/or Type IV of solar radio bursts. In the next step a neural network model was developed to determine the probability, with which flares will be followed by the geomagnetic response of a particular intensity. Enhancement of solar energetic particle flux was added to the set of input parameters. The results indicated that X-ray flares accompanied by solar radio bursts represent a good proxy of CMEs [2, 3]. This conclusion was now confirmed by the data from the period 2005 - 2012. Coronal holes are stable formations that can survive over several solar rotations. Corotating interaction regions (CIRs) between fast and slow solar wind can thus periodically pass over the Earth and cause recurrent geomagnetic storms. This periodicity makes the forecasts of the geomagnetic disturbances much easier [4] than in the case of eruptive phenomena. Our analysis confirmed that the strongest magnetic storms are caused by CMEs. Nevertheless, many geomagnetic disturbances in the active part of solar cycle are influenced by sequences of CMEs and CIRs, which increase their strength. [1] Bochníček, J., P. Hejda and F.

  20. Ten years of siting studies and public dialogue: the main lessons learnt at SKB

    It is more than 20 years since a co-ordinated nuclear waste management programme was set up in Sweden. Deep geological disposal of spent nuclear fuel in crystalline bedrock is the preferred option and an extensive R and D programme has been performed. A step-wise approach is being applied to development, technical demonstration and implementation of the disposal system. A key element of the programme is siting of the deep repository, which started in a focused manner almost ten years ago. Before that time a study-site drilling programme was performed 1977-85 and facilities for intermediate storage of the spent fuel (CLAB), final disposal of low and medium level waste (SFR) and underground research (Aespoe Hard Rock Laboratory) were sited during the 1980's [1, 2]. Thus, siting-related experiences to date within SKB encompasses: - Deep-drilling programme at about ten study-sites (1977-85). - Siting of CLAB, 1976-79. - Siting of SFR, 1980-83. - Siting of Aespoe HRL, 1986-90. - Feasibility studies on a voluntary basis in two municipalities in northern Sweden, Storuman and Mala, including local referenda 1995 and 1997. - Feasibility studies on a voluntary basis in six municipalities, Oesthammar, Nykoeping, Oskarshamn, Tierp, Hultsfred, Aelvkarleby, 1995-2001. By the end of this year SKB will present a comprehensive plan for the continuation of the siting programme at a few sites selected from the six municipalities where feasibility studies are now being finished.

    2014-01-01

    Full Text Available The use of acupuncture in inducing delivery has a long history in China. With progress over time, it has been applied in many aspects. For further study of acupuncture in delivery, this paper analyzed the papers using acupuncture in delivery in the past ten years in mainland China. 87 literatures were picked out by searching relevant electronic databases and bibliographies of relevant journals. The analysis showed randomized controlled trials that were the major type of research, while preclinical researches and literature reviews only account for around ten percent, respectively. Clinical researches indicated that acupuncture can relieve labor pain, promote maternal uterine contraction, shorten birth process, and treat postpartum disorders. Preclinical researches found that acupuncture can adjust certain hormones and improve uterus contraction of late-stage pregnant rats. However, due to lack of large multicenter randomized controlled clinical trials, standardized evaluations of clinical effects in clinical researches and detailed mechanism study in preclinical researches and unequivocal conclusions about the effectiveness, efficacy, and mechanisms of acupuncture in this field cannot be obtained from those researches yet. Further clinical and preclinical studies about the use of acupuncture in delivery with improved methodology is still needed.

  8. COLONIAL AND TRADITIONAL URBAN SPACE IN JAVA: A MORPHOLOGICAL STUDY OF TEN CITIES

    SUNARYO Rony Gunawan

    2013-01-01

    Full Text Available Most of morphological studies of cities in Java tended to place the elements of traditional urban space such as Alun-alun, Mosque, Palace and Market as the main elements of city. Other elements such as the colonial urban space Resident Office, Fort, Church, Park and so on are often considered separately or placed as a complementary part. Through a morphological study  by exploring ten cities in Java, I found both elements of traditional and colonial urban space were set in a unique and various pattern. There are some findings indicating that the elements of colonial urban space significantly influence the city structure as well as those of the traditional ones. Therefore, understanding the urban space form in Java should include and put elements of both of traditional and colonial urban space as an integral part.

    Full Text Available The present work has focused on the assessment of the tolerance of ten accessions of carrot (L1, L2, L3, F4, E5, R7, R8, L10, G11 and S12 to salt stress, grown in the region of Sidi Bouzid. The tests were carried out under plastic greenhouse (during 5 months. The results obtained show that the salt stress reduced the parameters of growth and production. However, a difference in the response to salt stress was recorded between the accessions studied. A reduction in yield of up to 70 % with the concentration 3 g / l of NaCl, for different accessions studied is recorded. However, the accession L1 who has given the longer roots and dry matter yield and the largest root shows the most tolerant accessions unlike L10, G11 and S12 which are the most sensitive.

    2013-01-01

    Full Text Available Abstract Background Medical school attrition is important - securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001–2011 and to study the personal effects of dropout on individual students. Methods The study included quantitative analysis of completed cohorts and qualitative analysis of ten-year data. Data were collected from individual student files, examination and admission records, exit interviews and staff interviews. Statistical analysis was carried out on five successive completed cohorts. Qualitative data from student files was transcribed and independently analysed by three authors. Data was coded and categorized and key themes were identified. Results Overall attrition rate was 5.7% (45/779 in 6 completed cohorts when students who transferred to other medical courses were excluded. Students from Kuwait and United Arab Emirates had the highest dropout rate (RR = 5.70, 95% Confidence Intervals 2.65 to 12.27;p  Absenteeism was documented in 30% of students, academic difficulty in 55.7%, social isolation in 20%, and psychological morbidity in 40% (higher than other studies. Qualitative analysis revealed recurrent themes of isolation, failure, and despair. Student Welfare services were only accessed by one-third of dropout students. Conclusions While dropout is often multifactorial, certain red flag signals may alert us to risk of dropout including non-EU origin, academic struggling, absenteeism, social isolation, depression and leave of absence. Psychological morbidity amongst dropout students is high and Student Welfare services should be actively promoted. Absenteeism should prompt early intervention. Behind every dropout statistic lies a personal story. All

    2002-09-01

    Full Text Available Hemicrania continua (HC is an uncommon primary headache first described as a syndrome in 1984. Being quite unusual, its clinical characterization still demands better description. The aim of this study is to present the main clinical characteristics of 10 patients with the diagnosis of HC seen in a tertiary center, critically discussing their main features. All subjects had strictly unilateral headache without side shift and absolute response to indomethacin. Seven patients (70% presented autonomic features during pain exacerbations. Four (40% had migrainous symptoms during the exacerbations and one presented partial relief with dihydroergotamine. One patient had pain excruciatingly severe during the exacerbations. Although the cardinal features of HC - continuous, unilateral, indomethacin responsive, remain strongly reliable, a refinement on the clinical characterization is needful and desired.Hemicrania continua (HC é uma cefaléia primária relativamente incomum primeiramente descrita enquanto sindrome em 1984. Por ser relativamente rara, sua apresentação clínica ainda carece de melhor descrição. O objetivo do presente estudo é apresentar e criticamente discutir as principais características clínicas de 10 pacientes com HC consecutivamente vistos em um centro de atendimento especializado. Todos os pacientes apresentavam cefaléia estritamente unilateral, sem alternância de lado e com absoluta resposta a indometacina. Sete pacientes (70% apresentavam sinais autonômicos durante a exacerbação da dor. Quatro (40% apresentavam sintomas migranosos durante as exacerbações e um apresentava alívio parcial com diidroergotamina. Um paciente apresentava exacerbações excruciantemente severas. Embora as principais características da HC - dor continua, unilateral, responsiva à indometacina - permaneçam extremamente associados à sindrome, um refinamento na caracterização clínica é necessário.

    Elalfy, Mohsen; Elbarbary, Nancy; Khaddah, Normine; Abdelwahab, Magy; El Rashidy, Farida; Hassab, Hoda; Al-Tonbary, Youssef

    2010-01-01

    Intracranial hemorrhage (ICH) is a rare but major cause of death in immune thrombocytopenic purpura (ITP). The authors reviewed data of 1,840 patient with ITP, from 5 pediatric hematology centers in Egypt from 1997 to 2007, to study the incidence and risk factors of ICH. Ten cases of ICH were identified with a median age at presentation of 7.5 years; 4 patients had acute ITP, 2 persistent and 4 chronic. The platelet count was late referral to a specialized center. Our results suggest that treatment does not prevent ICH and that it can occur at any time during the course of the disease. Delayed referral can be considered a risk factor for unfavorable outcome of ICH, highlighting the importance of teaching sessions for patients and their parents to minimize subsequent morbidity and mortality of ICH in children with ITP.

  13. A Pharmacogenetics Study in Mozambican Patients Treated with Nevirapine: Full Resequencing of TRAF3IP2 Gene Shows a Novel Association with SJS/TEN Susceptibility

    Cinzia Ciccacci

    2015-03-01

    Full Text Available Steven–Johnson Syndrome (SJS and Toxic Epidermal Necrolysis (TEN are severe adverse drug reactions, characterized by extensive epidermal detachment and erosions of mucous membrane. SJS/TEN is one of the most serious adverse reactions to Nevirapine (NVP treatment, commonly used in developing countries as first-line treatment of human immunodeficiency virus infection. In the last years TRAF3IP2 gene variants had been described as associated with susceptibility to several diseases such as psoriasis and psoriatic arthritis. We hypothesized that this gene, involved in immune response and in NF-κB activation, could also be implicated in the SJS/TEN susceptibility. We performed a full resequencing of TRAF3IP2 gene in a population of patients treated with NVP. Twenty-seven patients with NVP-induced SJS/TEN and 78 controls, all from Mozambique, were enrolled. We identified eight exonic and three intronic already described variants. The case/control association analysis highlighted an association between the rs76228616 SNP in exon 2 and the SJS/TEN susceptibility. In particular, the variant allele (C resulted significantly associated with a higher risk to develop SJS/TEN (p = 0.012 and OR = 3.65 (95% CI 1.33–10.01. A multivariate analysis by logistic regression confirmed its significant contribution (p = 0.027, OR = 4.39 (95% CI 1.19–16.23. In conclusion, our study suggests that a variant in TRAF3IP2 gene could be involved in susceptibility to SJS/TEN.

    2014-12-01

    Full Text Available Background: There is scarcity of data of the epidemiology of leukaemia in Arab countries including Yemen. Understanding patterns of leukaemia underpins epidemiology and can provide insight into disease etiology. The aim of this research is to determine the epidemiologic pattern of adult leukaemia in Yemen. Methods: The research is a descriptive cross-sectional study. We analyzed the data of 702 adult patients with leukaemia, who were newly diagnosed over a ten-year period between October 1999 and October 2009 at the referral haematology centre in Sana’a at Al-Jomhori Teaching Hospital, according to type of leukaemia, age, sex, geographic distribution and time of diagnosis. Results: Acute Myeloid Leukaemia (AML was found to be the most common (45.1% followed by Chronic Myeloid Leukaemia (CML (26.5%, Acute Lymphoid Leukaemia (ALL (17.7% and Chronic Lymphoid Leukaemia (CLL (10.7%, respectively. There was an almost equal prevalence of AML and CML for males and females but males had significantly more cases of ALL and CLL (p =0.008. A significant variation in geographic pattern showed that the highest number of cases is seen the Central mountainous region and the least number of cases in the South-eastern region which is coastal and lowland (p<0.001. The seasonal variation showed that higher number of ALL cases was seen in the summer months (33% compared with other seasons (21% in the spring, 24.2% in autumn and 21.8% in winter. Conclusions: The pattern of adult leukaemia in Yemen is different from that seen in western countries which could be attributed to different environmental exposure. The geographic pattern indicates a possible role of certain environmental factors which warrant further investigations. The pattern of seasonal variation needs further studies for evaluating the seasonality.

  16. Breath-hold two-dimensional MR angiography of coronary arteries. Comparison with conventional coronary angiography in ten cases

    Purpose: To assess the diagnostic value of two-dimensional coronary magnetic resonance (MR) angiography in patients evaluated for ischemic heart disease. Materials and methods: Ten patients who underwent selective cardiac catheterization with coronary MR angiography were evaluated with two-dimensional coronary MR angiography. Coronary MR angiography was performed with breath-hold fat-suppressed ECG-gated Turbo-FLASH with K-space segmentation using a 1.5 T imager. Results: The left main coronary artery, proximal left anterior descending artery, circumflex artery and right coronary artery were demonstrated in all cases. Continuous segments (mean) of left anterior descending, circumflex and right coronary arteries visualized on MRA were 6.72 +- 3.16 cm, 3.67 +- 4.81 cm and 7.93 +- 3.12 cm respectively. The overall sensitivity for detection of hemodynamically significant coronary artery lesion (≥50%) was 62.5% respectively. Conclusion: Breath-hold two-dimensional coronary MR angiography was useful in showing relatively long segments of the main coronary arteries and also has potential in depicting hemodynamically significant coronary artery lesions

  17. The study of multi-frequency scattering of ten radio pulsars

    Lewandowski, Wojciech; Kijak, Jaroslaw; Bhattacharyya, Bhaswati; Roy, Jayanta

    2015-01-01

    We present the results of the multi-frequency scatter time measurements for ten radio pulsars that were relatively less studied in this regard. The observations were performed using the Giant Meterwave Radio Telescope at the observing frequencies of 150, 235, 325, 610 and 1060~MHz. The data we collected, in conjunction with the results from other frequencies published earlier, allowed us to estimate the scatter time frequency scaling indices for eight of these sources. For PSR J1852$-$0635 it occurred that its profile undergoes a strong evolution with frequency, which makes the scatter time measurements difficult to perform, and for PSR J1835$-$1020 we were able to obtain reliable pulse broadening estimates at only two frequencies. We used the eight frequency scaling indices to estimate both: the electron density fluctuation strengths along the respective lines-of-sight, and the standardized amount of scattering at the frequency of 1 GHz. Combining the new data with the results published earlier by Lewandowsk...

  18. Japanese hospitals--culture and competition: a study of ten hospitals.

    Anbäcken, O

    1994-01-01

    Japanese health care is characterized by a pluralistic system with a high degree of private producers. Central government regulates the prices and the financing system. All citizens are covered by a mandatory employment-based health insurance operating on a non-profit basis. The consumer has a free choice of physician and hospital. A comparison between Japan, Sweden and some other countries shows significant dissimilarities in the length of stay, number of treatments per hospital bed and year and the staffing of hospitals. About 80 per cent of the hospitals and 94 per cent of the clinics are privately owned. The typical private hospital owned by a physician has less than 100 beds. In this paper, data collected (1992/93) in an empirical study of Japanese hospitals and their leadership is presented. Also discussed are the hospitals' style of management, tools and strategies for competition and competences--personal and formal skills required of the leadership in the hospital. There follows a study of ten hospitals, among which hospital directors and chief physicians were interviewed. Interviews are also made with key persons in the Ministry of Health and Welfare and other organizations in the health care field. The result is also analysed from a cultural perspective--'what kind of impact does the Japanese culture have on the health care organization?' and/or 'what kind of sub-culture is developed in the Japanese hospitals'. Some comparisons are made with Sweden, USA, Canada and Germany. The different roles of the professions in the hospital are included in the study as well as the incentives for different kinds of strategies--specialization, growing in size, investments in new equipment, different kind of ownership and hospitals. Another issue discussed is the attempt to uncover whether there is an implicit distribution of specialties--silent agreements between hospitals, etc. PMID:10137135

    Full Text Available The objective was to identify the main factors influencing micronutrient policies in the opinion of policy actors in ten European countries. Study was carried out during Jan-Nov 2010 in European countries: the Czech Republic, Denmark, England, Germany, Greece, Italy, the Netherlands, Norway, Poland and Spain. Semi-structured qualitative interviews were conducted with representatives of stakeholders involved in the vitamin D, folate and iodine policy making process. Fifty eight key informants representing mainly scientific advisory bodies (n=24 and governmental organisations (n=19 participated in the study. The remaining interviewees represented non-governmental organisations (n=6, industry (n=4 or were independent academic or health professional experts (n=5. Data were analysed by theoretical interpretative thematic analysis. Insights from interviewees on the development of micronutrient policies were grouped using the Public Health Nutrition Policy-making model. The main factors influencing the micronutrient policies were: systematic monitoring of nutrition and health, causal relationships between consumers’ diet-related behaviours and health outcomes, scientific recommendations from national bodies (Science area; scientific recommendations from international authorities and experiences of other countries, EU legislation, cultural factors (Wider context and political environment, national capacity to deal with the problem, national legislation, economics, stakeholder engagement, relationships between stakeholders (Policy and institutions area. The spectrum and weight of the factors influencing nutritional policy depends on nutrient, country and degree of its “advanced status” within nutrition policy, political environment, culture and socio-economic conditions as well as the point of view (who is expressing the opinion.

    2008-10-01

    Full Text Available The aim of this paper is to investigate the interface between the formal and informal support provided to very old people against a background of increasing need for care and a decreasing number of potential informal caregivers. We used a sample of 323 community-dwelling octogenarians participating in the Swiss Interdisciplinary Longitudinal Study on the Oldest Old (SWILSOO (n=1441 interviews. Descriptive analyses and a multilevel model were used to test whether formal and informal services complemented or substituted one another. The study revealed that the amount of informal services increased significantly as the frequency of formal aid increased, indicating that the two networks were complementary in the majority of the cases. In 21.2% of the cases, the formal network partly substituted the informal network (as an adjustment and only in 6.4% of the cases did the informal support end after the formal support had increased (radical substitution. The concern that the introduction of formal services may curb the readiness of relatives and friends to provide care is thus unfounded.

    2001-06-01

    Full Text Available In the past ten years, 45 cases of infantile spasm treated in our center. From these patients, 15 cases received only steroid, other 15 cases only clonazepam, and the rest, a combination of clonazepam and steroid. All patients were observed for two years. This is a retrospective study, the data being extracted from patients record. A number of patients were treated in ambulatory and the others were patients of the hospital. The result of comparison of optimal control of seizures are as follow: 1 In only steroid group 27 percent of the patients were free of seizure, 2 In only clonazepam group 28 percent showed no seizure, 3 in combined clonazepam and steroid group 39% were seizure-free. Based on this trial we believe that treatment of infantile spasm with combined steroid and clonazepam is better than any of them alone. Considering these results, we believe that the treatment of infantile spasm with a combination of steroid and clonazepam is preferable to these drugs.

    2010-06-01

    Full Text Available Abstract Background Reminiscence is the systematic use of memories and recollections to strengthen self-identity and self-worth. The study aim was to investigate the consequences for nursing home residents and staff of integrating reminiscence into daily nursing care. Methods In this randomised study, ten nursing homes were matched into two groups on the basis of location, type and size. In the period August 2006 - August 2007, staff in the Intervention Group were trained and supported in the use of reminiscence, involving individual and group sessions with residents as well as reminiscence boxes, posters and exhibitions. At baseline and again 6 and 12 months after the intervention start, data were collected on residents' cognitive level, agitated behaviour, general functioning and proxy-assessed quality of life, as well as on staff well-being and job satisfaction. Mixed linear modelling was used to analyse differences in outcome between the intervention and control groups. Results Project drop-out rates were 32% for residents and 38% for nursing staff. Most staff in the Intervention Group considered reminiscence a useful tool that improved their communication with residents, and that they would recommend to other nursing homes. There were no significant differences between residents in the Intervention and the Control Group in cognitive level, agitated behaviour or general functioning. Residents in the Intervention Group showed significant higher score at 6 months in quality of life subscale 'Response to surroundings', but there was no significant difference at 12 months. Positive effects of reminiscence were observed for all staff outcome measures, the only exception being SF-12 self-rated physical health. At 6 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Personal accomplishment, Emotional exhaustion, Depersonalisation, 'Attitude towards individual

  8. Malaria in pregnancy; facts from the parasitology laboratory: a ten-year study in Abuja, North Central Nigeria

    Ibecheozor, N.K.O

    2014-09-01

    Full Text Available Malaria, which is transmitted by female Anopheles mosquitoes, is the major cause of mortality among the pregnant women in the sub-Saharan Africa. A ten year study of malaria in pregnancy was carried out in Abuja, North Central Nigeria. Thick and thin blood films were stained with the Giemsa methodology. Of the 16760 pregnant women blood samples, 4571 (27.3% were positive for malaria parasites caused by Plasmodium falciparum. Of the 4571 positive cases, 75 (1.7% had parasite density of >5000 parasites/µl of blood; 148 (3.2% had between 500-5000 parasites/µl of blood; 520 (11.4% had between 50 - 500 parasites/µl of blood; while 3828 (83.7% had between 5-50 parasites/µl of blood. With the current estimate of over 4500 deaths of pregnant women in Nigeria due to malaria annually, we must make deliberate efforts to stop these unacceptable and painful losses. The continued use of malaria rapid diagnostic tests (M-RDTs methodologies should be discontinued because of its negative implications. Therefore, the microscopic laboratory diagnostic component should be included in ANC at all level of health care facility.

  9. Ten-year study on varieties of parotid tumors in pediatrics

    Parotid tumors are uncommon because they account for 0.5 % of all types of cancer in pediatrics. They generally occur as increased local asymptomatic volume, occasionally accompanied by pain and inflammatory signs. A retrospective, longitudinal and descriptive study was carried out to determine the frequency and forms of presentation of parotid tumors diagnosed in 0-18 years-old patients, who had been admitted to the oncological surgery service of 'William Soler' pediatric hospital from February 2001 to December 2010. The variables taken into account were sex, forms of presentation, response to treatment as well as the histological variants presented, with the objective of giving information about these variants of parotid tumors in pediatrics, which, despite their rareness, represent a high risk group when occur. Seven patients were diagnosed, of whom 3 were pleomorphic adenomas, one adenocarcinoma, one mucoepidermoid carcinoma of the gland, one parotid Hodgkin lymphoma and one mixed tumor with atypical cells of the gland. The onset of all the tumors was the presence of a parotid mass in 6 asymptomatic cases and in one case suffering local pain. They were all performed gland ultrasound and aspiration fine needle biopsy. Males prevailed over the females (ratio of 5:2) and the average age of presentation was 12.3 years. Surgery is the main therapeutic weapon in most of cases. It was recommended to closely follow the patients because of their high rate of local recurrence

  11. Equity in HIV testing: evidence from a cross-sectional study in ten Southern African countries

    Mitchell Steven

    2010-09-01

    Full Text Available Abstract Background HIV testing with counseling is an integral component of most national HIV and AIDS prevention strategies in southern Africa. Equity in testing implies that people at higher risk for HIV such as women; those who do not use condoms consistently; those with multiple partners; those who have suffered gender based violence; and those who are unable to implement prevention choices (the choice-disabled are tested and can have access to treatment. Methods We conducted a household survey of 24,069 people in nationally stratified random samples of communities in Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. We asked about testing for HIV in the last 12 months, intention to test, and about HIV risk behaviour, socioeconomic indicators, access to information, and attitudes related to stigma. Results Across the ten countries, seven out of every ten people said they planned to have an HIV test but the actual proportion tested in the last 12 months varied from 24% in Mozambique to 64% in Botswana. Generally, people at higher risk of HIV were not more likely to have been tested in the last year than those at lower risk, although women were more likely than men to have been tested in six of the ten countries. In Swaziland, those who experienced partner violence were more likely to test, but in Botswana those who were choice-disabled for condom use were less likely to be tested. The two most consistent factors associated with HIV testing across the countries were having heard about HIV/AIDS from a clinic or health centre, and having talked to someone about HIV and AIDS. Conclusions HIV testing programmes need to encourage people at higher risk of HIV to get tested, particularly those who do not interact regularly with the health system. Service providers need to recognise that some people are not able to implement HIV preventive actions and may not feel empowered to get themselves

    2016-01-01

    In order to comprehend the impact of music therapy or music therapy processes, a researcher might look for an approach where the topic under investigation can be understood within a broader context. This calls for a rich inclusion of data and consequently a limited number of participants and may be...... achieved through the use of objectivist case study research. The strength of the case study design is that it allows for uncovering or suggesting causal relationships in real-life settings through an intensive and rich collection of data. According to Hilliard (1993), the opposite applies for extensive...... designs, in which a small amount of data is gathered on a large number of subjects. With the richness of data, the intensive design is ―the primary pragmatic reason for engaging in single-case or small N research‖ (p. 374) and for working from an idiographic rather than a nomothetic perspective....

    2011-11-01

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

    1997-09-01

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

    1989-07-01

    This series of three case studies illustrates the validity and usefulness of MIDAS, a microcomputer-based tool for integrated resource planning under uncertainty. The first, at Union Electric, serves to test and validate the model and to illustrate its use for demand/supply option evaluation. Focusing on nuclear plant life extension, the Virginia Power case demonstrates the model's extensive detail, particularly in the production cost and financial areas, as well as its flexibility in addressing approximately 70 uncertainty scenarios. Puget Sound Power Light, the third case, used MIDAS for the preparation of its integrated resource plan. A 108-endpoint decision tree illustrates the full power of the decision analysis capability.

  1. Triacylglycerols in some underutilised tropical seed oils 1. Systematic studies of ten oils

    Triacylglycerols composition of ten lesser known and underutilised tropical seed oils have been determined. The seed oils include Monodora tenuifolia, Monodora myristica, Colocynthis citrullus, Cyperus esculentus, Cucumeropsis edulis, Andenopus breviflorus, Telfairia occidentalis, Blighia sapida, Antiaris africana and Sesame indicum. In the Moreaceae family (M. tenuifolia, M. myristica) the dominant triacylglycerol are OPO/POO, LLO, OOL, and OOO. They accounted for over 60% of the total triacylglycerol content in the oils. In the Cyperaceae family (C. esculentus), OPP/POO, POL and OOO accounted for over 80% of the total triacylglycerol content. In the Cucurbitaceae family, SSP was the dominant triacylglycerol specie in A. breviflorus, while OPO/POO and OOO were the dominant species in C. citrullus and C. edulis. Blighia sapida recorded a different distribution of triacylglycerols composition. PLL occurred at the highest concentration, while other high molecular weight triacylglycerols were also identified in the oil. They include, SSA, OSA, LSA, OAA and LLA. Analysis of A. antiaris oil showed a different pattern in the distribution of the triacylglycerols. LaLaM, MMLa and LaLaLa accounted for about 80% of the total triacylglycerols. This result reflected the fatty acid composition of the oil. Lauric acid (C12:0) and Myristic acid (C14:0) accounted for 71.5% of the total fatty acid. The possible use of the oils as cocoa butter equivalents CBEs and cocoa butter substitutes CBSs are discussed. (author)

    2004-01-01

    Objective To investigate the genetic relation among ten ethnic groups in northwest China. Methods Allele frequencies of six STR(short tandem repeat ) loci in D13S1358, VWA, FGA, D5S818, D13S317, and D7S820 were collected from Lasa Tibetan, Changdu Tibetan, Xian Han, Gansu Dongxiang, Gansu Yugu, Xinjiang Uygur, Ozbak, Kirgiz, Sibe, Ningxia Hui by the results of State Key laboratory, Forensic Science Department, school of medical, Xian Jiaotong University and internet biological information data bank, and compared with that of the Mongolian, Zhuang in China, and White and Negro in USA. The polymorphism index (H, DP, PPE, PIC) and genetic distance, then the phylogenetic tree of all population were reported. Results The resulting tree topology exhibited strong geographic and racial partitioning consistent with that obtained with HLA and classical genetic polymorphisms. Conclusion The results suggest that forensic STR loci may be particularly powerful tools and provide the necessary fine resolution for the reconstruction of recent human evolutionary history.

    2007-02-01

    Full Text Available Background & Objective: Primary dysmenorrhoea (PD is definedas the occurrence of painful menstrual cramps of uterine origin which occurs in the absence of any underlying disease. The pathogenesis is unclear, but uterine hyperactivity, elevated prostaglandin and leukotrienes levels, and hormonal level fluctuations have all been implicated. The objective of this study was to evaluate the effect of TENS on the hormones cortisol and prolactin in individuals with PD.Methods: Plasma levels of cortisol and prolactin were studied in twenty-one (21 subjects with PD by obtaining blood samples from each subject pre-and post-TENS therapy on the first day of menstruation. The mean age of subjects was 23 (+ 2 years.  The Visual Analogue Scale (VAS was used to assess the pre-and post-treatment pain intensity.  The TENS unit was applied for a duration of 30 minutes.Results: A paired t-test showed that there was an overall reduction in the mean cortisol and prolactin from  pre treatment values of 28.45µg/dl ((5.27 and 56.81ng/ml ((31.86 to post treatment values of 27.33µg/dl ((5.13 and 53.23ng/ml ((37.63 respectively. However, these differences were not statistically significant (P>0.05.  Pain intensity was significantly reduced comparing pre and post treatment VAS scores (P = 0.001.Conclusion: The probable mechanism by which TENS effected alterations in cortisol and prolactin levels and pain reduction in subjects with PD might be through the opioid-modulating analgesia system, which releases B-endorphins and other endogenous opiates in response to pain.  This is because there is a close relationship between B-endorphin, cortisol and neurons, which secrete dopamine into the hypothalamic-pituitary-portal system.

CFR for men was 32.10% and for women 35.29%. The main factor indicative of bad prognosis was a short hospitalization period. It was observed that 30.38% of our ...

  8. Study on trace elements of ten kinds of fish species at Beijing market by INAA

    Background: As the improvement of the living standard, the safety of food becomes more and more concerned currently. The fish is healthy food with more protein but less fat. Purpose: We bought ten species of fish from the market, which are often eaten by Chinese, and analyzed the trace elements of them by instrumental neutron activation analysis (INAA). So some detecting methods should be applied to give some suggestions for human. Methods: First of all, we choose six species of fresh water fish, including grass carp, weever, Wuchang Fish, tilapia, crucian, carp, and four species of frozen sea fish, including hairtail, yellow croaker, salmon, ling. All of them were collected from a supermarket in Beijing. Secondly, we remove the squama by Teflon coated scissor, wash the fish with de-ionized water and use ashless filter paper to absorb the water on the fish. Then we cut the squama-less part with titanium knife for about 10 g, put them into plastic bags separately and sealed, balance the net weight, use a tablet machine to press them into slice and freeze at -18℃ for 12 h. And then we put them into a vacuum desiccator to pump for 72 h, balance dry fish, calculate the ratio of moisture and triturate the sample into about 40 meshes in agate. Finally, we prepare three sub-samples about 300 mg with each packed by plastic bag for analysis. We put the samples, NIST-1632a and chemical standard material together, irradiate in micro neutron source reactor (MNSR) for 16 h, measure the radioactivity by Ge detector after cooling 5 d or 10 d, and calculate the contents of 16 elements by the ko-NAA and the relative method. Results: The contents of trace elements are different between fresh water fish and sea fish. The contents of As, Hg, Br: Na, Se in sea fish are apparently higher than fresh water fish, but the contents of Rb and Zn are contrary. Considering most fresh water fishes are feed, Zn was probably added in fodder. The content of As in weever is 2.4 μg·g-1, the

  9. NOx trade. Case studies

    Some of the questions with respect to the trade of nitrogen oxides that businesses in the Netherlands have to deal with are dealt with: should a business buy or sell rights for NOx emission; which measures must be taken to reduce NOx emission; how much must be invested; and how to deal with uncertainties with regard to prices. Simulations were carried out with the MOSES model to find the answers to those questions. Results of some case studies are presented, focusing on the chemical sector in the Netherlands. Finally, the financial (dis)advantages of NOx trade and the related uncertainties for a single enterprise are discussed

  10. A Further Study on the Ten-Penny Problem%十文钱问题再探

    肖前国; 张凤华; 苟娜

    2012-01-01

    The ten-penny problem, an old Chinese reasoning illusion problem, was investigated by Li and Zhang for the first time ( 2008), which indicated that only 30% of the subjects succeeded in solving the problem, and resulted in a high error rate in the singleentry bookkeeping representation. However, the fact that most of the resolved-subjects also adopted the single-entry bookkeeping representation strategy was ignored in their studies. Therefore, it may not be appropriate to attribute the high error rate to the single-entry bookkeeping representation strategy. Based on the above analysis, three studies were conducted, and the chi-square test was used for most of the data analysis. In the first study, 198 undergraduate students were asked to solve the ten-penny problem and its heterogeneous issue. They were also required to write down on a booklet their explanations for their solutions. In the second experiment, we changed the presentation of the original problem and the modified problem by weakening the statements for studying whether this change improved their reasoning performance. In the third study, we provided two different cues. One was an external perceptual cue that was embodied by underlining some key state- ments, and the other internal cue required the subjects to apply critical thinking skills to read and resolve the original problem and the modified problem in the instruction. The results of three experiments indicated that ( 1 ) the subjects showed a error rate as high as on the heterogeneous issue of the ten-penny problem; (2) weakening the version of the ten-penny problem significantly improved the correct rate of reasoning; ( 3 ) presenting critical thinking clues also significantly improved the subjects' performance on the ten-penny problem. The results supported the hypotheses that the ten-penny problem was a reasoning illusion problem. The difficulty in solving this problem may be due to ① the surface character of the statement

    Full Text Available Abstract Background Congenital anomalies and their primary prevention are a crucial public health issue. This work aimed to estimate the prevalence of congenital anomalies in Brindisi, a city in southeastern Italy at high risk of environmental crisis. Methods This research concerned newborns up to 28 days of age, born between 2001 and 2010 to mothers resident in Brindisi and discharged with a diagnosis of congenital anomaly. We classified cases according to the coding system adopted by the European Network for the Surveillance of Congenital Anomalies (EUROCAT. Prevalence rates of congenital anomalies in Brindisi were compared with those reported by EUROCAT. Logistic regression models were adapted to evaluate the association between congenital anomalies and municipality of residence of the mother during pregnancy. Results Out of 8,503 newborns we recorded 194 subjects with congenital anomalies (228.2/10,000 total births, 1.2 times higher than the one reported by the EUROCAT pool of registries. We observed 83 subjects with congenital heart diseases with an excess of 49.1%. Odds Ratios for congenital heart diseases significantly increased for newborns to mothers resident in Brindisi (OR 1.75 CI 95% 1.30-2.35. Conclusions Our findings indicated an increased prevalence of Congenital Anomalies (especially congenital heart diseases in the city of Brindisi. More research is needed in order to analyze the role of factors potentially involved in the causation of congenital anomalies.

  15. Vertebral Angiosarcoma. Case Study.

    Guzik, Grzegorz

    2015-01-01

    Bone angiosarcomas, especially vertebral angiosarcomas, are very rare. There are no studies based on large clinical samples in the literature, and only a few single case reports can be found. The symptoms of the disease are not specific. It is usually detected incidentally or at a late stage when pathological vertebral fractures or neurological complications occur. Diagnostic imaging and history help to recognize the tumour behind the symptoms, but do not allow accurate clinical diagnosis. The basis for a diagnosis is the histopathological examination supported by immunohistochemistry (IHC) assays. The case of a 26-year-old woman with an angiosarcoma involving the eighth thoracic vertebra we report reflects diagnostic problems adversely affecting the efficacy and accuracy of treatment offered to patients. The patient underwent three surgeries of the spine, including two biopsies. A needle biopsy did not provide sufficient information for the diagnosis. An open excisional biopsy, which at the same time temporarily reduced neurological deficits in the patient, was the only chance to obtain an accurate diagnosis. The third surgery was posterior decompression of the spinal cord due to the rapidly escalating paraparesis. It was not until 8 weeks later that the final diagnosis was established. At that time, the patient could not be qualified for any supplementary treatment. The patient died in hospital 6 months after the onset of disease. PMID:26468177

  17. Ego-resiliency development from late adolescence to emerging adulthood: A ten-year longitudinal study.

    Alessandri, Guido; Eisenberg, Nancy; Vecchione, Michele; Caprara, Gian Vittorio; Milioni, Michela

    2016-07-01

    This study examined the development of ego-resiliency from late adolescence to emerging adulthood, using a 10-year cohort-sequential design. Participants were 335 Italian adolescents (173 females and 162 males), living, at the time of the study, in Genzano, a small city near to Rome. Latent growth curve analyses indicated that the developmental trajectory of ego-resiliency from 15 to 25 years is adequately described by a piecewise model that included separate growth profiles corresponding to different developmental stages. Essentially, ego-resiliency remained remarkably stable until the end of high school, and then encountered a phase of relative increase. Moreover, the trajectory of ego-resiliency from ages 15 to 19 was predicted by self-efficacy beliefs in managing negative emotions, and the trajectory from age 19 to 25 was predicted by experienced familial support and self-efficacy beliefs in expressing positive emotions at age 15. Experienced stressful life events also accounted for individuals' deviation from the typical ego-resiliency trajectory. PMID:27236209

  18. Unemployment, immigration, and NAFTA: a panel study of ten major U.S. industries.

    Amuedo Dorantes, C; Huang W-c

    1997-01-01

    The potential employment effects of the North American Free Trade Agreement (NAFTA) was the central concern of debate before the treaty was eventually passed. Panel data on unemployment rates in 10 major industries in the US during 1983-1994 were analyzed to assess the sensitivity of unemployment rates with respect to industry characteristics, macroeconomic variables, and Canadian and Mexican immigration to the US in the aftermath of the advent of NAFTA. The industries studied are mining; construction, durable goods, nondurable goods, transportation and public utilities; wholesale and retail trade; finance, insurance, and real estate; services; agriculture; and government. Analysis of the data determined that the output produced by the industry, unemployment insurance coverage, and interest rates are significant determinants of industry unemployment rates, but union presence does not affect industry unemployment. Both Canadian and Mexican immigrants seem to complement the US labor force, with Canadian immigrants being highly complementary to US labor. The Chow test found no evidence that NAFTA has changed the structure of unemployment determination in the industries studied. PMID:12321541

  19. Conclusions from a ten year study of oxygen-18 in precipitation and runoff in Sweden

    Monthly oxygen isotope data from seventeen precipitation stations and eleven river stations are presented for the years 1978-1985. The spatial and temporal variations are described by period mean δ18O values and amplitudes of the seasonal component. The irregular fluctuations superimposed on the seasonal variation are studied. Whilst distance dependent correlations between stations are found there are no significant correlations to temperature or atmospheric moisture content on a monthly time-scale. Relations between precipitation input and river water output are discussed in terms of mean δ18O shift and seasonal amplitude damping. Estimates of mean residence times are also given. A fair agreement with what can be expected from simple catchment characteristics is obtained. (author). 6 refs, 8 figs, 3 tabs

    2012-02-01

    Full Text Available Abstract Background Central sensitization has recently been documented in patients with knee osteoarthritis (OAk. So far, the presence of central sensitization has not been considered as a confounding factor in studies assessing the pain inhibitory effect of tens on osteoarthritis of the knee. The purpose of this study is to explore the pain inhibitory effect of burst tens in OAk patients and to explore the prognostic value of central sensitization on the pain inhibitory effect of tens in OAk patients. Methods Patients with knee pain due to OAk will be recruited through advertisements in local media. Temporal summation, before and after a heterotopic noxious conditioning stimulation, will be measured. In addition, pain on a numeric rating score, WOMAC subscores for pain and function and global perceived effect will be assessed. Patients will be randomly allocated to one of two treatment groups (tens, sham tens. Follow-up measurements will be scheduled after a period of 6 and 12 weeks. Discussion Tens influences pain through the electrical stimulation of low-threshold A-beta cutaneous fibers. The responsiveness of central pain-signaling neurons of centrally sensitized OAk patients may be augmented to the input of these electrical stimuli. This would encompass an adverse therapy effect of tens. To increase treatment effectiveness it might be interesting to identify a subgroup of symptomatic OAk patients, i.e., non-sensitized patients, who are likely to benefit from burst tens.

    2011-01-01

    Full Text Available Little is known about the relationship between temperament and character inventory (TCI profiles and depressive symptoms. Personality profiles are useful, because personality traits may have different effects on depressive symptoms when combined with different combinations of other traits. Participants were from the population-based Young Finns study with repeated measurements in 1997, 2001, and 2007 (=1402 to 1902. TCI was administered in 1997 and mild depressive symptoms (modified Beck’s depression inventory, BDI were reported in 1997, 2001, and 2007. BDI-II was also administered in 2007. We found that high harm avoidance and low self-directedness related strongly to depressive symptoms. In addition, sensitive (NHR and fanatical people (ScT were especially vulnerable to depressive symptoms. high novelty seeking and reward dependence increased depressive symptoms when harm avoidance was high. These associations were very similar in cross-sectional and longitudinal analysis. Personality profiles help in understanding the complex associations between depressive symptoms and personality.

  2. Evaluating the Cause of Death in Obese Individuals: A Ten-Year Medical Autopsy Study

    2015-01-01

    Full Text Available Background. Obesity is a growing public health problem associated with increased morbidity and rate of death. Postmortem examination is imperative to determine the cause of death, to detect clinically unsuspected disease entities, and consequently to determine the actual impact of obesity on patient mortality. Methods. A total of 849 adult autopsies were retrospectively reviewed. Obese (BMI ≥ 30 kg/m2 and nonobese patients were separately studied. The primary cause of death in each group was categorized into malignancy, infection, stroke, ischemic and nonischemic heart disease, pulmonary embolism, hemorrhage, and primary nonneoplastic diseases of different organ systems. Results. Of 849 autopsies, 32.3% were obese. The leading causes of death in the obese population were malignancy (31.4%, infection (25.9%, ischemic heart disease (12.8%, and pulmonary embolism (6.2%. Obese individuals were statistically more likely to die from pulmonary embolism and liver disease and less likely to die from neurologic diseases and nonischemic heart disease. Conclusion. Autopsies on obese individuals constitute a third of all adult medical autopsies in our center. Increased death rates in the obese due to pulmonary embolism and liver disease should receive special clinical attention. Autopsy findings in the obese population should contribute to overall premortem disease detection, prevention, and management.

    In 1976, an accidental explosion in a plant near Seveso, Italy, caused the contamination of a populated area by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The area was subdivided into three zones (A, B, and R) having decreasing mean levels of TCDD soil contamination. This study examines the mortality between 1976 and 1986 among the subjects, aged 20-74 years, who were resident in the area since the accident (n = 556 in zone A, n = 3,920 in zone B, n = 26,227 in zone R). Subjects' exposure was classified by residence. A referent cohort of 167,391 subjects who lived in the immediate surroundings was concurrently examined. Vital status ascertainment was successful for over 99% of the subjects. Increased mortality from cardiovascular causes was found; incident-related stressors were considered more relevant to increased mortality than was TCDD exposure. Mortality from several cancers was elevated. The increases in biliary cancer (females), brain cancer, and lymphatic and hemopoietic neoplasms (particularly leukemia in males) did not appear to result from chance, confounding, or information/comparison bias. However, no definite patterns related to exposure classification were apparent. Merely suggestive increases in soft tissue tumors and melanoma were also noted. Liver and breast cancer mortality tended to be below expectations. Interpretation is hampered by the short observation period, small number of deaths from certain causes, and poor exposure definition. Further research is in progress.

  4. Ten-Year Retrospective Longitudinal-Study of Student Perspectives on Value of REU

    Slater, T. F.; Slater, S. J.

    2013-12-01

    For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational

  5. Goiania incident case study

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

  7. FMCT verification: Case studies

    Full text: How to manage the trade-off between the need for transparency and the concern about the disclosure of sensitive information would be a key issue during the negotiations of FMCT verification provision. This paper will explore the general concerns on FMCT verification; and demonstrate what verification measures might be applied to those reprocessing and enrichment plants. A primary goal of an FMCT will be to have the five declared nuclear weapon states and the three that operate unsafeguarded nuclear facilities become parties. One focus in negotiating the FMCT will be verification. Appropriate verification measures should be applied in each case. Most importantly, FMCT verification would focus, in the first instance, on these states' fissile material production facilities. After the FMCT enters into force, all these facilities should be declared. Some would continue operating to produce civil nuclear power or to produce fissile material for non- explosive military uses. The verification measures necessary for these operating facilities would be essentially IAEA safeguards, as currently being applied to non-nuclear weapon states under the NPT. However, some production facilities would be declared and shut down. Thus, one important task of the FMCT verifications will be to confirm the status of these closed facilities. As case studies, this paper will focus on the verification of those shutdown facilities. The FMCT verification system for former military facilities would have to differ in some ways from traditional IAEA safeguards. For example, there could be concerns about the potential loss of sensitive information at these facilities or at collocated facilities. Eventually, some safeguards measures such as environmental sampling might be seen as too intrusive. Thus, effective but less intrusive verification measures may be needed. Some sensitive nuclear facilities would be subject for the first time to international inspections, which could raise concerns

  8. Termination: A Case Study.

    Friedberg, Ahron L

    2015-12-01

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

  10. Endovascular treatment of false-aneurysm ten years after dacron patch aortoplasty for coarctation of the aortic isthmus. Report of a case.

    Illuminati, Giulio; Pacilè, Maria Antonietta; Palumbo, Piergaspare; Salvatori, Filippo Maria; Vietri, Francesco

    2013-01-01

    False aneurysm degeneration is a known complication of patch aortoplasty for coarctation of the aortic isthmus. Open surgical treatment consists of prosthetic graft repair of the involved aorta, often requires circulatory arrest to achieve a safe proximal aortic control and perform proximal anastomosis, and finally is associated with substantial perioperative morbidity. Endografting of the diseased aorta is a valuable alternative to open repair, when feasible, with good short and long term results. We now report one more case of false aneurysm ten years after Dacron patch aortoplasty for isthmic coarctation in a 26-year-old woman, successfully treated by endovascular repair via the left common iliac artery, and a complete exclusion of the aneurysm at two year follow-up.

  12. Adjunct High Frequency Transcutaneous Electric Stimulation (TENS) for Postoperative Pain Management during Weaning from Epidural Analgesia Following Colon Surgery: Results from a Controlled Pilot Study.

    Bjerså, Kristofer; Jildenstaal, Pether; Jakobsson, Jan; Egardt, Madelene; Fagevik Olsén, Monika

    2015-12-01

    The potential benefit of nonpharmacological adjunctive therapy is not well-studied following major abdominal surgery. The aim of the present study was to investigate transcutaneous electrical nerve stimulation (TENS) as a complementary nonpharmacological analgesia intervention during weaning from epidural analgesia (EDA) after open lower abdominal surgery. Patients were randomized to TENS and sham TENS during weaning from EDA. The effects on pain at rest, following short walk, and after deep breath were assessed by visual analog scale (VAS) grading. Number of patients assessed was lower than calculated because of change in clinical routine. Pain scores overall were low. A trend of lower pain scores was observed in the active TENS group of patients; a statistical significance between the groups was found for the pain lying prone in bed (p < .05). This controlled pilot study indicates benefits of TENS use in postoperative pain management during weaning from EDA after open colon surgery. Further studies are warranted in order to verify the potential beneficial effects from TENS during weaning from EDA after open, lower abdominal surgery. PMID:26541070

    Based on the interpretation of composite imagery of band 4, 3, 2 of Landsat 5 in 2000 and 2009, analyzed, study area changes of the landscape pattern were analyzed. The landscape pattern evolution in the context of climate change was investigated combined with the meteorological data of 30 years to reveal the relationship between environment and climate change. Results showed that both forestland and grassland areas were increased over the past decade. However, the overall ecological environment of studied area degenerated reflecting in significant reduction of water and low wetland meadow as well as increased low salt meadow area. The temperatures of studied areas rise significantly under the background of global warming. The ecological environment became worse with uneven distribution of seasonal rainfall and persistent drought. Both agriculture and animal husbandry production were affected. Based on above analysis the following strategies were suggested to restore and improve the ecological environment, eventually realize the regional sustainable development in the context of climate change; strengthen ecological and environmental protection, limit or eliminate the interference factors of causing ecosystem degradation, make full use of the system self-healing capabilities.%利用2000年和2009年2个时期的Landsat 5的4,3,2(RGB)波段合成影像的解译结果,分析研究区近10年的景观格局变化,并结合气象数据,探讨景观格局在气候背景下的演变规律,揭示生态环境变化与气候变化的关系.结果表明:10年来研究区林地和草地面积有所增加,但区域整体生态环境还是呈退化趋势,表现为水域及低湿地草甸的大量减少和低地盐化草甸的增加;在全球气候变暖背景下,研究区气温上升趋势明显,加上降水量季节分布不均,持续的干旱使生态环境变得更差,农牧业生产受到极大影响.基于分析结果,指出在气候变化背景下,应加强生态环境

  17. COMPARATIVE STUDY BETWEEN TITANIUM ELASTIC NAILING (TENS AND DYNAMIC COMPRESSION PLATING (DCP IN THE TREATMENT OF FEMORAL DIAPHYSEAL FRACTURES IN CHILDREN

    Ramasubba Reddy

    2015-08-01

    Full Text Available BACKGROUND : Orthopaedic surgeons have long maintained that all children who have sustained a diaphyseal fracture of femur recover with c onservative treatment, given the excellent remodeling ability of immature bone in children. Angulations, shortenings and malrotations are not always corrected by conservative treatment. Of many surgical options, titanium elastic nailing has been the newer implant which is being used regularly. Although good results have been reported with elastic intramedullary nails, plate fixation continues to be a viable alternative in surgical treatment of femoral shaft fractures. However there are not many studies comp aring the efficiency of titanium elastic nailing and plating for femoral diaphyseal fractures in pediatric age group. AIM : The present study aims to compare the surgical management of diaphyseal fractures of femur in children with Dynamic Compression Plati ng versus Titanium Elastic Nailing. DESIGN : This is a prospective study . MATERIALS AND METHODS : This prospective study was conducted in a tertiary hospital. Patients who presented to the out - patient department and casualty of the hospital with femoral diap hyseal fractures during April 2012 to June 2014 were considered for the study. Subjects fulfilling the predetermined inclusion and exclusion criteria were included in the study. STATISTICAL METHODS : Fisher Exact test, Chi - Square Test, Student t test (Two t ailed, independent . RESULTS : Patients in the age group of 6 - 14 years were considered for the study, Patients were divided into two groups and treated with DCP/TENS. The duration of surgery, hospital stay, and, amount of blood loss was minimal in TENS grou p. Callus was seen early in TENS group. Radiological union was early in TENS group by 2 - 3 weeks. Outcome was better in patients treated with TENS (Excellent - 70%; Satisfactory – 30%; Poor - 0% in comparison to DCP (Excellent - 70%; Satisfactory - 25%; Poor - 5%. CO NCLUSION : TENS

    Full Text Available Background : Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are the most severe adverse drug reactions in children. Objectives : The objective was to study the causative drugs and outcome in children with SJS, SJS-TEN overlap, and TEN. Materials and Methods : Retrospective analysis of all the in-patient records of children below 18 years of age with the diagnosis of SJS, SJS-TEN overlap, and TEN was carried out. Results and Conclusions : Twenty children were identified, eight patients each were diagnosed as SJS and TEN and four as SJS-TEN overlap. Multiple drugs were implicated in 15 cases while single drug was responsible in 5 cases. Antibiotics (40.7% were implicated as the commonest cause followed by NSAIDS (25.9% and anticonvulsants (7.4%. Seventeen patients recovered completely and three patients died.

  19. Theory testing using case studies

    Dissing Sørensen, Pernille; Løkke Nielsen, Ann-Kristina

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus on...... the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications...... for research design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes...

  20. Do Karst Rivers “deserve” their own biotic index? A ten years study on macrozoobenthos in Croatia

    Rađa Biljana

    2010-07-01

    Full Text Available In this study we present the results of a ten year survey of the aquatic macroinvertebrate fauna along four karst rivers: Jadro, Žrnovnica, Grab and Ruda, all of them situated in the Middle Dalmatia region of Croatia, in an attempt to construct the Iliric Biotic Index, which will be more applicable for the water quality analysis than the most frequently applied biotic index in Croatia, the Italian Modification of Extended Biotic Index. The rivers geologically belong to the Dinaric karst, unique geological phenomena in Europe. Benthic macroinvertebrates were collected along each river at 15 sites by standard methods of sampling along with several physicochemical parameters, including: temperature, dissolved oxygen, carbon dioxide, alkalinity, hardness and pH. Univariate and multivariate techniques revealed differences in the macroinvertebrate community structure as well as in physicochemical parameters between the Karst rivers and continental rivers. Based on those differences, the Iliric Biotic Index was proposed as the standard of karst river water quality in Croatia in accordance with the EU Water Framework Directive. Differences between the Iliric Biotic Index and the most commonly used biotic indices in the European Community and the USA (The Biological Monitoring Working Party (B.M.W.P. scores, i.e. Extended Biotic Index, Indice Biotique, Family Biotic Index suggest that karst rivers need a new biotic index.

    2013-11-01

    The Hokkaido Study on Environment and Children's Health is an ongoing cohort study that began in 2002. The study consists of two prospective birth cohorts, the Sapporo cohort (n = 514) and the Hokkaido large-scale cohort (n = 20,940). The primary goals of this study are to first examine the potential negative effects of perinatal environmental chemical exposures on birth outcomes, including congenital malformations and growth retardation; second, to evaluate the development of allergies, infectious diseases and neurodevelopmental disorders and perform longitudinal observations of the children's physical development to clarify the causal relationship between these outcomes and environmental chemicals; third, to identify individuals genetically susceptible to environmental chemicals; finally, to identify the additive effects of various environmental factors in our daily life, such as secondhand smoke exposure or low folate intake during early pregnancy. In this paper, we introduce our recent progress in the Hokkaido study with a cohort profile updated in 2013. For the last ten years, we followed pregnant women and their offspring, measuring various environmental chemicals, i.e., PCB, OH-PCB and dioxins, PFCs (Perfluorinated Compounds), Organochlorine pesticides, Phthalates, bisphenol A and mercury. We discovered that the concentration of toxic equivalents (TEQ) of dioxin and other specific congeners of PCDF or PCDD have effects on birth weight, infants' neurodevelopment and immune function. There were significant gender differences in these effects; our results suggest that male infants have more susceptibility to those chemical exposures than female infants. Interestingly, we found maternal genetic polymorphisms in AHR, CYP1A1 or GSTs that significantly modified the dioxin concentrations in maternal blood, suggesting different dioxin accumulations in the bodies of individuals with these genotypes, which would lead to different dioxin exposure levels. These genetic

  8. Case Studies in Science Ethics

    Williams, Karen

    2010-03-01

    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

    Atuk, N O; McDonald, T; Wood, T; Carpenter, J T; Walzak, M P; Donaldson, M; Gillenwater, J Y

    1979-05-01

    Long-term epidemiological and laboratory studies were carried out in a kindred with familial pheochromocytoma associated with von Hippel-Lindau disease. Thirteen members were affected by the syndrome and the trait appears to be transmitted in an autosomal dominant fashion. Of 13 patients, 7 had pheochromocytoma alone. Of the remaining six patients, one had pheochromocytoma combined with von Hippel-Lindau disease, four had pheochromocytoma with retinal disease only, and a single patient had a retinal lesion without pheochromocytoma. In four patients, pheochromocytoma antedated the development of retinal lesions. Ten members also had mild hypercalcemia without accompanying elevations of PTH in the 4 patients in whom this was determined. In all, hypercalcemia was corrected with removal of tumors, and no patient had a return of hypercalcemia in the absence of recurrent increases in urinary catecholamines. The clinical presentations in 12 patients varied markedly, as did their urinary excretion rates of norepinephrine, epinephrine and their metabolites. However, an analysis of the data revealed significant correlations not previously described between the urinary excretion of free catecholamines (norepinephrine plus epinephrine), blood pressure, the free catecholamine content of the tumor and the age of the patient. Urinary excretion of free norepinephrine plus epinephrine appear to be decreased with advancing age (p less than 0.001). Both systolic and diastolic blood pressures and the age of the patient were inversely correlated (p less than 0.01). A significant inverse relationship between the tumor content of free catecholamines and the age of the patients was, although to a lesser degree, also present (p less than 0.05). As a whole, the size of the tumors and their norepinephrine content were not correlated. We present a concept that, in familial pheochromocytoma, the metabolism of catecholamines is altered by the process of aging, and that this change modifies the

  10. Poroelastic behaviour of the degenerating human intervertebral disc: a ten-day study in a loaded disc culture system

    KS Emanuel

    2015-06-01

    Full Text Available The intervertebral disc (IVD allows flexibility to the vertebral column, and transfers the predominant axial loads during daily activities. Its axial biomechanical behaviour is poroelastic, due to the water-binding and releasing capacity of the nucleus pulposus. Degeneration of the intervertebral disc presumably affects both the instantaneous elastic response to the load on the IVD and the subsequent interstitial flow of fluid. This study aims to quantify the poroelastic behaviour of the IVD and its change with degeneration, as defined by the magnetic resonance imaging-based Pfirrmann Score (PS. For a period of ten days, 36 human lumbar IVDs were loaded with a simulated physiological axial loading regime, while deformation was monitored. The IVDs responded to the loads with instantaneous elastic and slow poroelastic axial deformation. Several mechanical parameters changed throughout the first five days of the experiment, until the IVDs settled into a dynamic equilibrium. In this equilibrium, degeneration was significantly related to a decrease in disc height loss during the daytime high load phase (ρ = -0.49, and to a decrease in the rate of this deformation during the final half hour of each day (ρ = -0.53. These properties were related to the nucleus glycosaminoglycan/hydroxyproline (GAG/HYP ratio, rather than GAG content alone, indicating that remodelling of the extracellular matrix reduces poroelastic properties of the IVD. This implies that the degenerated discs have a reduced capacity to bind water and/or a reduced resistance against fluid flow. The resulting loss in hydrostatic pressure may further change cell behaviour in the nucleus pulposus.

  11. Teaching astronomy with case studies

    Slater, Timothy F.

    2015-11-01

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

  20. Incidence of cancer in children residing in ten jurisdictions of the Mexican Republic: importance of the Cancer registry (a population-based study)

    In 1996, Mexico started to register cases of childhood cancer. Here, we describe the incidence of cancer in children, residing in ten Mexican jurisdictions, who were treated by the Instituto Mexicano del Seguro Social (IMSS). New cases of childhood cancer, which were registered prospectively in nine principal Medical Centers of IMSS during the periods 1998–2000 (five jurisdictions) and 1996–2002 (five jurisdictions), were analyzed. Personnel were specifically trained to register, capture, and encode information. For each of these jurisdictions, the frequency, average annual age-standardized incidence (AAS) and average annual incidence per period by sex and, age, were calculated (rates per 1,000,000 children/years). In total 2,615 new cases of cancer were registered, with the male/female ratio generally >1, but in some tumors there were more cases in females (retinoblastoma, germ cells tumors). The principal groups of neoplasms in seven jurisdictions were leukemias, central nervous system tumors (CNS tumors), and lymphomas, and the combined frequency for these three groups was 62.6 to 77.2%. Most frequently found (five jurisdictions) was the North American-European pattern (leukemias-CNS tumors-lymphomas). Eight jurisdictions had AAS within the range reported in the world literature. The highest incidence was found for children underless than five year of age. In eight jurisdictions, leukemia had high incidence (>50). The AAS of lymphomas was between 1.9 to 28.6. Chiapas and Guerrero had the highest AAS of CNS tumors (31.9 and 30.3, respectively). The frequency and incidence of neuroblastoma was low. Chiapas had the highest incidence of retinoblastoma (21.8). Germ-cell tumors had high incidence. The North American-European pattern of cancers was the principal one found; the overall incidence was within the range reported worldwide. In general but particularly in two jurisdictions (Yucatán and Chiapas), it will be necessary to carry out studies concerning the

  1. Study on Climatic Variation and Its Effect on Vegetable Type Soybean Genotypes at Khumaltar, Lalitpur in the Last Ten Years

    2015-03-01

    Full Text Available Soybean (Glycine max L. Merril is widely grown in the mid hills as intercrop with maize or in paddy bunds, while it is gaining popularity as sole crop in terai and inner terai. Mean temperature at Khumaltar during soybean growing period was mostly fluctuating; but we observed an increasing trend in temperature. Amount of rainfall was not changed dramatically but number of rainy days was decreased during study period. Rainfall during germination time increase soil moisture which also increase germination and found higher early stand. Days from sowing to 50% flowering and 90% maturity were short in the case of higher minimum temperature and low rainfall. Among the genotypes, AGS-377, AGS-378, AGS-379 and Tarkari Bhattmas-1 were more sensitive. However, seed yield decreased in the case of higher temperatures and low rainfall. Cool night temperatures and high moisture increased disease incidence in soybean which, eventually reduced yield. In last three years, plant suffered from moisture stress during early vegetative stage and high moisture during late vegetative stage which reduced seed yield and seed weight. In conclusion, we found that genotypes like AGS- 360, Sathiya and Tarkari Bhatmas-1 are very sensitive to climatic variation.

    2013-05-01

    Full Text Available Os trigonum syndrome is one of the rare causes of posterior foot pain. Ostrigonum, which is placed at the posterior of talus, is an accessory bone. Ostrigonum syndrome causes back foot pain due to compression between talusand calcaneus. In this study, we present a case of os trigonum syndrome ,which is a rare disease and is generally missed. A 65-year-old female patientwith a complaint of left foot pain for the last 2 months persented to our outpatientclinic. In the physical examination, plantar flexion of the ankle andtoe was painful. Patient’s pain was evaluated by the visual analog scale andnoted as 8 cm. There was sensitivity at the posterior of talus during palpation.Os trigonum syndrome was diagnosed based on radiological examinationsand a physical therapy program consisting of transcutaneous electrical nervestimulation (TENS, cold pack, foot and ankle range of motion and strengtheningexercises was started. After the treatment, pain VAS decreased to 2cm,and then the patient was followed clinically. As in our case, os trigonum syndromeshould also be taken into consideration in patients complaining withposterior foot pain apart from other frequently encountered causes. In suchcases, physical therapy programs are very effective in pain management andin reducing the cost of treatment. Turk J Phys Med Rehab 2013;59:161-4.

  6. Experimental study of a fast plasma focus discharge operated in the range of tens of joules emitting neutrons

    In this doctoral research, a small plasma focus discharge operated at tens of joules and kilo amperes has been experimentally studied. This device produces a coaxial discharge by an electrode arrange which consists of an inner electrode, a cylindrical insulator, and an outer electrode. The discharge is driven by a capacitive generator and it is operated at pressures of some millibars. Typical electrical parameters of the device are T/4∼150ns, 160 nF, 40 nH, 30-100J, 40-70kA. When Deuterium is used as filling gas, neutrons are produced by fusion reactions. The device, namely PF-50J, is one of the most extreme plasma focus reported in the literature to emit neutrons. The results of this work have demonstrated that the same dynamics found in larger machines (operated from kJ to MJ) is also found in this extremely low energy device which means that after the discharge is initiated, a plasma sheet is formed over the insulator. By the action of the Lorentz force, the plasma sheet moves axially. When the sheet reaches the top end of the inner electrode, it starts to implode radially to finally form a dense plasma column (pinch). Finally, the plasma column is disrupted 5-10ns after column formation. Shock piston velocities of the order of 104-105m/s were estimated from experiments for each discharge dynamical phase. Typical pinch densities of 1024-25m-3 were also observed in PF-50J. An interesting feature observed in this work is the formation of axial jet-like structures which appears at late times almost hundred nanoseconds after pinch disruption. These structures are composed by a metallic plasma which results from ablation of the inner electrode. The mechanism responsible for the formation of this kind of structure is still unknown, although evidence suggests that the phenomena is not related to the pinch formation process. One of the principal motivations of this thesis was to study the optimization for neutron emission in the PF-50J device. This plasma focus is

  8. Ten years of PAMELA

    Spillantini, Piero

    2016-07-01

    Pamela experiment has been designed as a cosmic ray observatory at 1 AU, dedicated to the precise and high statistics study of CR fluxes on a three decades energy range, form a few tens MeV up to several hundred GeV region. It is the last step of the 'Russian-Italian Mission' (RIM) program born in 1992 between several Italian and Russian institutes and with the participation of the Royal Institute of Technology of Stockholm (Sweden) and the Siegen University (German). Launched the 16 June 2006 from Baikonur cosmodrome on board of the Resurs-DK1 Russian satellite by a Soyuz rocket in an elliptical (350-610 km) quasi polar orbit (70° inclination) it was activated on 21 June 2006, afterword has been in a continuous data taking mode for ten years. The Pamela program pays particular attention to the study of particles (protons and electrons) and antiparticles (antiprotons and positrons) energy spectra. It also includes search for possible signals of dark matter annihilation, search for primordial antimatter (antihelium), search for new Matter in the Universe (Strangelets?), study of cosmic-ray propagation, solar physics and solar modulation, terrestrial magnetosphere. This program is made possible thanks to the outstanding performance of the instrument, the low energy threshold, the quasi-polar orbit, the 10 years duration of the observation. Protons and helium nuclei are the most abundant components of the cosmic radiation and the precise measurements of their fluxes allow understanding the acceleration and propagation of cosmic rays in the Galaxy. Their spectral shapes cannot be well described by a single power law: at 230-240 GV they exhibit an abrupt spectral hardening. They challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy. Of paramount importance is the discover of the anomalous increase of the positron flux at energies higher that 50 GeV (the so called 'Pamela anomaly'). The review of

  9. Probabilistic consequence study of residual radiological effects from a hypothetical ten-ton inadvertent nuclear yield. Weapons Safety Program

    In this paper we study the potential radiological consequences of a strategic bomber accident, in which one of the assumed on-board nuclear weapons explodes with an arbitrarily chosen 10-ton nuclear yield. The frequency of such an occurrence is infinitesimal. The safety design features in today s nuclear weapons' systems essentially forbid its occurrence. We have a chosen a military base which has the feature of being a representative combination of urban and rural populations. The assumed ''crash site'' is near the northwest comer of the military base, close to civilian housing located just across the street from the base. A worst case wind would be from the ESE (east south east). This would cause fission debris to be dispersed toward the largest population centers and, thus, would lead to the largest Pu ''collective'' doses (i.e., a dose integrated over time and summed over individuals). Also, if an ESE wind were blowing at accident time, some people in nearby housing could receive lethal gamma-ray doses from fallout before evacuation could occur. It is assumed only one weapon undergoes nuclear yield; the other on-board weapons would HE detonate and the Pu would be aerosolized and lofted. We assume an activity-size distribution and lofting similar to those used to predict fallout measured at NTS. The main thrust of our study is to provide estimates of probabilistic radiological risks to the population local to a strategic bomber crash site. The studied radiological consequences are: cloud-passage doses from Pu inhalation; doses from groundshine due to gamma-producing radionuclides; and areal contamination from Pu and the long-lived fission products Cs-137 and Sr-90

  10. Ten Problems in Experimental Mathematics

    Bailey, David H.; Borwein, Jonathan M.; Kapoor, Vishaal; Weisstein, Eric

    2004-09-30

    This article was stimulated by the recent SIAM ''100 DigitChallenge'' of Nick Trefethen, beautifully described in a recent book. Indeed, these ten numeric challenge problems are also listed in a recent book by two of present authors, where they are followed by the ten symbolic/numeric challenge problems that are discussed in this article. Our intent was to present ten problems that are characteristic of the sorts of problems that commonly arise in ''experimental mathematics''. The challenge in each case is to obtain a high precision numeric evaluation of the quantity, and then, if possible, to obtain a symbolic answer, ideally one with proof. Our goal in this article is to provide solutions to these ten problems, and in the process present a concise account of how one combines symbolic and numeric computation, which may be termed ''hybrid computation'', in the process of mathematical discovery.

  11. Endometriosis-associated ovarian cancer: A ten-year cohort study of women living in the Estrie Region of Quebec, Canada

    2010-01-01

    Full Text Available Abstract Objectives Endometriosis has been believed to increase the risk of developing ovarian cancer, but recent data supporting this hypothesis are lacking. The aim of this study was to verify whether the incidence of endometriosis, ovarian cancer and the both increased during the last 10 years among women living in the Estrie region of Quebec. Methods We collected data of women diagnosed with endometriosis, ovarian cancer or both, between 1997 and 2006, from a population living in the Estrie region of Quebec. We performed this retrospective cross-sectional study from the CIRESSS (Centre Informatisé de Recherche Évaluative en Services et Soins de Santé system, the database of the CHUS (Centre Hospitalier Universitaire of Sherbrooke, Sherbrooke, Canada. Results Among the 2854 identified patients, 2521 had endometriosis, 292 patients had ovarian cancer and 41 patients had both ovarian cancer and endometriosis. We showed a constant increase in the number of ovarian cancer (OC between 1997 and 2006 (r2 = 0.557, P = 0.013, which is not the case for endometriosis (ENDO or endometriosis-associated ovarian cancer (EAOC. The mean age ± SD was 40.0 ± 9.9 and 53.9 ± 11.4 for patients having ENDO and OC, respectively. Mean age of women with EAOC was 48.3 ± 10.8, suggesting an early onset of ovarian cancer in women having endometriosis of about 5.5 years average, P = 0.003. Women with ENDO were at increased risk for developing OC (Rate Ratio [RR] = 1.6; 95% Confidence Interval [CI] = 1.12-2.09. Pathological analyses showed the predominance of endometrioid type (24.4% and clear-cell type (21.9% types in EAOC compared to OC, P = 0.0070 and 0.0029, respectively. However, the serous type is the most widespread in OC (44.5% in comparison to EAOC (19.51%, P = 0.0023. Conclusion Our findings highlight that the number of cases of ovarian cancer is constantly increasing in the last ten years and that endometriosis represents a serious risk factor which

    Full Text Available Background: The masculine mammal cancer is extremely infrequent, so many authors consider it as a truly clinical rareness. Objectives: To describe the clinical-pathological behaviour of the mammal cancer in men in the province of Cienfuegos. Method: A descriptive-retrospective study was carried out of all the cases of mammal cancer in men, submitted to surgery in the Universitary Hospital "Dr Gustavo Aldereguia Lima” of Cienfuegos, between January 1996 and December 2005. The variables were: age, affected mamma, topographic localization of the tumour, clinical stage in the moment of diagnosis, histological variant, type of biopsy used, surgical technique applied, and health area. Results: The mayority of cases was registered in the 61-70 age group (44.4%; and respecting benign tumors, it was found in the 31-40 age group with 9 cases (31.3%. An increase incidence was observed in the last seven years, as well as its detection in quite advanced stages. Conclusions: It is necessary to find mechanisms to establish ways of early detection of the mammal tumours in the province, for which it is essential, the clinical personnel preparation and the dispensarization of all the men presenting factors for the mammal tumour.

  15. Structure is three to ten times more conserved than sequence--a study of structural response in protein cores.

    Illergård, Kristoffer; Ardell, David H; Elofsson, Arne

    2009-11-15

    Protein structures change during evolution in response to mutations. Here, we analyze the mapping between sequence and structure in a set of structurally aligned protein domains. To avoid artifacts, we restricted our attention only to the core components of these structures. We found that on average, using different measures of structural change, protein cores evolve linearly with evolutionary distance (amino acid substitutions per site). This is true irrespective of which measure of structural change we used, whether RMSD or discrete structural descriptors for secondary structure, accessibility, or contacts. This linear response allows us to quantify the claim that structure is more conserved than sequence. Using structural alphabets of similar cardinality to the sequence alphabet, structural cores evolve three to ten times slower than sequences. Although we observed an average linear response, we found a wide variance. Different domain families varied fivefold in structural response to evolution. An attempt to categorically analyze this variance among subgroups by structural and functional category revealed only one statistically significant trend. This trend can be explained by the fact that beta-sheets change faster than alpha-helices, most likely due to that they are shorter and that change occurs at the ends of the secondary structure elements.

    1993-05-01

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

  17. The 'fine structure' of nutrient dynamics in rivers: ten years of study using high-frequency monitoring

    A complete appraisal of material fluxes in flowing waters is really only possibly with high time resolution data synchronous with measurements of discharge. Defined by Kirchner et al. (2004; Hydrological Processes, 18/7) as the high-frequency wave of the future and with regard to disentangling signal noise from process pattern, this challenge has been met in terms of nutrient flux monitoring by automated bankside analysis. In Ireland over a ten-year period, time-series nutrient data collected on a sub-hourly basis in rivers have been used to distinguish fluxes from different catchment sources and pathways and to provide more certain temporal pictures of flux for the comparative definition of catchment nutrient dynamics. In catchments where nutrient fluxes are particularly high and exhibit a mix of extreme diffuse and point source influences, high time resolution data analysis indicates that there are no satisfactory statistical proxies for seasonal or annual flux predictions that use coarse datasets. Or at least exposes the limits of statistical approaches to catchment scale and hydrological response. This has profound implications for catchment monitoring programmes that rely on modelled relationships. However, using high resolution monitoring for long term assessments of catchment mitigation measures comes with further challenges. Sustaining continuous wet chemistry analysis at river stations is resource intensive in terms of capital, maintenance and quality assurance. Furthermore, big data capture requires investment in data management systems and analysis. These two institutional challenges are magnified when considering the extended time period required to identify the influences of land-based nutrient control measures on water based systems. Separating the 'climate signal' from the 'source signal' in river nutrient flux data is a major analysis challenge; more so when tackled with anything but higher resolution data. Nevertheless, there is scope to lower

    Pyramid FILMS

    1977-01-01

    Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative powers of ten—10-1 m (10 centimeters), and so forth, until we are viewing a carbon nucl...

  19. Case studies in canonical stewardship.

    1985-11-01

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

  20. A parathyroid scintigraphy case study

    O' Leary, Desiree [UCD School of Diagnostic Imaging, St Anthony' s Campus, Herbert Avenue, Dublin 4 (Ireland)]. E-mail: desiree.oleary@ucd.ie

    2005-05-01

    Background: There has been much debate concerning the most suitable protocol for parathyroid scintigraphy; the merits of various radiopharmaceuticals versus the correct imaging protocol to visualise both ectopic and anatomically placed adenomas against the various equipment choices have been debated. Aim: To demonstrate, through the use of a case study, the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion. Method: Use is made of Tc99mMIBI, full field chest scintigraphy, a clearly defined imaging protocol and SPECT imaging to locate ectopic parathyroid tissue in a female patient with significant symptoms of parathyroid hyperfunction. Results: A single hyperfunctioning adenoma is located in the pre-carinal area of the mediastinum. Using a radioguided surgical technique the hyperfunctioning tissue is excised and confirmed by histopathology. Conclusion: Whilst a dramatic reduction in patient symptoms was not seen immediately in this patient, the symptoms of the illness have been subsiding since January 2003. This case study demonstrates the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion.

The cumulative radiation doses with respect to γ-radiation, were 0.024, 0.168 and 0.336 Gy. T-lymphocyte proliferation was shown to be activated with all radiation doses mentioned above but with doses of 0.024 and 0.168 Gy, helper T lymphocytes, and with 0.336 Gy, suppressor N-lymphocytes were primarilly activated. 9 refs., 7 figs., 2 tabs

  2. Powers of ten

    Innocenti, Pier Giorgio

    1979-01-01

    Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The idea for the film appears to have come from the 1957 book Cosmic View by Kees Boeke. The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative pow...

    2015-05-01

    Full Text Available The ultimate objective of manufacturing industries is to increase productivity with high quality. At present, many manufacturing companies are facing problems such as high quality rejection, high inventories, high lead time, high costs of production, and inability to cope with customer orders. By implementing and practicing the lean production system many problems can be solved without employing high-tech and high-touch approaches but by involving people on the shop floor in Kaizen activities. Kaizen is one of the powerful tools of lean manufacturing. Kaizen refers to continuous improvement in performance, cost and quality. Kaizen ensures that manufacturing processes become leaner and fitter, but eliminate waste (problem where value is added. The main objective of this paper is to provide a background on kaizen, present an overview of kaizen concepts that are used to transform a company into a high performing lean enterprise. A case study of implementation of Kaizen‟s has been discussed.

    Full Text Available Background. To control the malaria mortality, the global and national communities have worked together and produced impressive results in the world. Some of the Asian counties’ malaria mortality rate is more compared to countries with high health facilities around the world. This paper’s main aim is to describe trend of malaria cases and mortality in 10 Asian countries using the World Health Organization data. Methods. Malaria mortality data was collected systematically from WHO and UN database for the period 2006–2011. We estimated malaria mortality by age and countries. We also explored the dynamic relationships among malaria death rate, total populations, and geographical region using a map. During 2006–2011, the average malaria death per 10,000 population of all ages was 0.239 (95% CI 0.104 to 0.373, of children aged less than 5 year 1.143 (0.598 to 1.687, and of age greater than 5 years 0.089 (0.043 to 0.137 in Asian countries. Malaria prevalence per 10,000 populations steadily decreased from 486.7 in 2006 to 298.9 in 2011. Conclusion. The findings show that malaria mortality is higher for children aged less than 5 years compared with with adults selected in Asian countries except Sri Lanka.

  11. Mood and Menopause: Findings from the Study of Women’s Health Across the Nation (SWAN) over ten years

    Bromberger, Joyce T.; Kravitz, Howard M.

    2011-01-01

    Women are twice as likely as men to suffer from depressive symptoms and disorder. Considerable research has focused on the physiological and psychosocial differences between men and women as sources of depression. An important target of study has been the periods of reproductive changes and events that occur at puberty, postpartum and menopause. A controversy has existed regarding the extent to which, if at all, the menopausal transition or postmenopause increases the risk for elevated depressive symptoms and/or disorders. SWAN provided an opportunity to address the issue with the largest, most representative and diverse cohort currently available for study. The current paper presents the findings from analyses conducted on data collected from the larger core SWAN study and an ancillary study on mental health begun in Pittsburgh in 1995. We found, as did four other recent longitudinal studies, that risk for high depressive symptoms and disorder is greater during and possibly after the menopausal transition. Multiple other factors contribute to risk for depression in our SWAN cohort. PMID:21961723

  13. Quantifying Wetland Functions: A Case Study

    Potter, K. W.; Rogers, J. S.; Hoffman, A. R.; Wu, C.; Hoopes, J. A.; Armstrong, D. E.

    2007-05-01

    Wetlands are reputed to reduce peak flows and improve water quality by trapping sediment and phosphorus. However, there are relatively few studies that quantify these wetland functions. This paper reports on a study of a 45-hectare wetland in southern Wisconsin. The wetland is traversed by a stream channel that drains a predominantly agricultural 17.4 km2 watershed. During the spring and summer of 2006, we collected stage data and water samples at stations upstream and downstream of the wetland, with the former accounting for 82% of the contributing area. Continuous measurements of water stage at these stations were used to construct a streamflow record. During storm events water samples were taken automatically at 2-hour intervals for the first 12 samples and 8-hour intervals for the next 12 samples. Samples were analyzed for total suspended solids, total phosphorus, and dissolved reactive phosphorus. Ten events were observed during the observation period; the two largest events were 1 to 2-year storms. One-dimensional unsteady flow routing was used to estimate the maximum extent of wetland inundation for each event. When normalized for flow volume, all peak flows were attenuated by the wetland, with the maximum attenuation corresponding to the intermediate events. The reduced attenuation of the larger events appears to be due to filling of storage, either due to antecedent conditions or the event itself. In the case of sediment, the amount leaving the wetland in the two largest storms, which accounted for 96% of the exported sediment during the period of observation, was twice the amount entering the wetland. The failure of the wetland to trap sediment is apparently due to the role of drainage ditches, which trap sediment during the wetland-filling phase and release it during drainage. The export of sediment during the largest events appears to result from remobilization of sediment deposited in the low-gradient stream channel during smaller events. This

  19. Low-dose strontium-90 irradiation is effective in preventing the recurrence of pterygia: a ten-year study.

    Xue-jiao Qin

    Full Text Available BACKGROUND: To study the long-term effects of low-dosage strontium-90 (Sr90 irradiation on the recurrence of pterygium. METHODOLOGY/PRINCIPAL FINDINGS: One hundred twenty eyes from 104 patients with primary or recurrent pterygia were treated with surgery followed by Sr90 irradiation. In brief, starting on the sixth day after surgery, patients were treated with irradiation three times every other day at a total combined dosage of 2000 cGy to 3000 cGy. Corneal topography was used to evaluate ocular surface regularity before and after treatment. Patient follow-up was performed 2 days, 5 days, 2 weeks, 1 month, 3 months, 1 year, 5 years, and 10 years after surgery. Recurrence of pterygium was not observed in any of the patients in this study. Obvious cataract progression was observed in 6 eyes, which may be due to aging. During follow-up studies, only one eye was reported with dryness and foreign-body sensation. Significant pterygium-induced astigmatism was observed in corneal topography, which decreased after surgery. CONCLUSIONS/SIGNIFICANCE: Sr90 irradiation is effective in preventing the recurrence of primary and recurrent pterygia. We recommend delivering a total combined dosage of 2000 cGy to 3000 cGy of Sr90 irradiation administered in three batches every other day starting from the sixth day after surgery. Surgery is important in the rapid recovery of the cornea from pterygium-induced astigmatism.

  2. Statics and dynamics of the ten-state mean-field Potts glass model: a Monte Carlo study

    We investigate by means of Monte Carlo simulations the fully connected p-state Potts model for different system sizes in order to see how the static and dynamic properties of a finite model compare with the, exactly known, behaviour of the system in the thermodynamic limit. Using p=10 we are able to study the equilibrium dynamics for system sizes as large as N=2560. We find that the static quantities, such as the energy, the entropy, the spin glass susceptibility as well as the distribution of the order parameter P(q) show very strong finite-size effects. From P(q) we calculate the fourth-order cumulant g4(N,T) and the Guerra parameter G(N,T) and show that these quantities cannot be used to locate the static transition temperature for the system sizes investigated. Also the spin-autocorrelation function C(t) shows strong finite-size effects in that it does not show a plateau even for temperatures around the dynamical critical temperature TD. We show that the dependence on N and T of the -relaxation time can be understood by means of a dynamical finite-size scaling ansatz. C(t) does not obey the time-temperature superposition principle for temperatures around TD, but does so for significantly lower T. Finally we study the relaxation dynamics of the individual spins and show that their dependence on time depends strongly on the chosen spin, i.e. that the system is dynamically very heterogeneous, which explains the non-exponentiality of C(t).

    2014-01-01

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

    Full Text Available Our study evaluates the long-term effect of microalbuminuria on mortality among patients with acute myocardial infarction. We followed 151 patients from 1996 to 2007 to investigate if microalbuminuria is a risk factor in coronary heart disease. All patients admitted with acute myocardial infarction in 1996 were included. At baseline, we recorded urinary albumin/creatinine concentration ratio, body mass index, blood pressure, left ventricle ejection fraction by echocardiography, smoking status, medication, diabetes, age, and gender. Deaths were traced in 2007 by means of the Danish Personal Identification Register. Microalbuminuria, defined as a urinary albumin/creatinine concentration ratio above 0.65 mg/mmoL, occurred in 50% of the patients and was associated with increased all-cause mortality. Thus, 68% of the patients with microalbuminuria versus 48% of the patients without microalbuminuria had died during the 10 years of follow-up (P=0.04. The crude hazard ratio for death associated with microalbuminuria was 1.78 (CI: 1.18-2.68 (P=0.006, whereas the gender- and age-adjusted hazard ratio was 1.71 (CI: 1.03-2.83 (P=0.04. We concluded that microalbuminuria in hospitalized patients with acute myocardial infarction is prognostic for increased long-term mortality. We recommend measurement of microalbuminuria to be included as a baseline risk factor in patients with acute myocardial infarction and in future trials in patients with cor-onary heart disease.

  7. Recovery potential of a western lowland gorilla population following a major Ebola outbreak: results from a ten year study.

    Céline Genton

    Full Text Available Investigating the recovery capacity of wildlife populations following demographic crashes is of great interest to ecologists and conservationists. Opportunities to study these aspects are rare due to the difficulty of monitoring populations both before and after a demographic crash. Ebola outbreaks in central Africa have killed up to 95% of the individuals in affected western lowland gorilla (Gorilla gorilla gorilla populations. Assessing whether and how fast affected populations recover is essential for the conservation of this critically endangered taxon. The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004. This allowed us to describe Ebola's short-term and long-term impacts on the structure of the population. The size of the population, which included around 380 gorillas before the Ebola outbreak, dropped to less than 40 individuals after the outbreak. It then remained stable for six years after the outbreak. However, the demographic structure of this small population has significantly changed. Although several solitary males have disappeared, the immigration of adult females, the formation of new breeding groups, and several birth events suggest that the population is showing potential to recover. During the outbreak, surviving adult and subadult females joined old solitary silverbacks. Those females were subsequently observed joining young silverbacks, forming new breeding groups where they later gave birth. Interestingly, some females were observed joining silverbacks that were unlikely to have sired their infant, but no infanticide was observed. The consequences of the Ebola outbreak on the population structure were different two years and six years after the outbreak. Therefore, our results could be used as demographic indicators to detect and date outbreaks that have happened in other, non

Social science may be strengthened by the execution......This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most...... useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one...

  16. L’utilisation du TENS en physiothérapie : la situation particulière des soins palliatifs oncologiques

    Laliberté, Maude; Dyer, Joseph-Omer

    2012-01-01

    Trans-cutaneous electrical nerve stimulation (TENS) is a treatment against pain that uses the application of an electric current. Some studies suggest that TENS would reduce the pain associated with certain types of cancer and this treatment is regularly used in therapy in contexts of interdisciplinary practice specializing in palliative oncology. However, the use of TENS in cancer cases is a matter of controversy, and its application is contraindicated by Canadian standards governing the pra...

  17. Theoretical study on ten Λ-S states of Si2(-) anion: potential energy curves, spectroscopy and spin-orbit couplings.

    2013-05-01

    The potential energy curves (PECs) of seventeen Ω states generated from the ten Λ-S states of the Si2(-) anion are studied in detail using an ab initio quantum chemical method for the first time. The PECs are calculated for internuclear separations from 0.10 to 1.20 nm by the complete active space self-consistent field method, which is followed by the internally contracted multireference configuration interaction approach with the Davidson modification. The spin-orbit coupling is accounted for by the Breit-Pauli Hamiltonian. Core-valence correlation and scalar relativistic corrections are considered. Core-valence correlation corrections are included using an aug-cc-pCVTZ basis set. Scalar relativistic correction calculations are made with the third-order Douglas-Kroll Hamiltonian approximation at the level of a cc-pV5Z basis set. Obvious effect of core-valence correlation corrections on the PECs is observed, in particular for the two lowest (2)Πu and (2)Σg(+) Λ-S states. All the PECs are extrapolated to the complete basis set limit. The lowest (2)Πu Λ-S state is found to be the ground state of Si2(-) anion. The convergence observations of present calculations are made and the convergent behavior is discussed with respect to the basis set and level of theory. The effects of core-electron correlations on the energy splitting are studied by the all-electron aug-cc-pCVTZ basis set. Using these PECs, the spectroscopic parameters of Λ-S and Ω states involved are determined. The vibrational manifolds are evaluated for each Λ-S and Ω state of non-rotation Si2(-) anion. It shows that the spectroscopic parameters and molecular constants of ten Λ-S and seventeen Ω states reported here can be expected to be reliable predicted ones. PMID:23501942

  18. A study on heparin in complex with L1 protein of ten high risk Human Papillomavirus: new structural insights based on in silico analysis

    2015-01-01

    Full Text Available Human papillomavirus (HPV is one of the most common causes of sexually transmitted diseases in both men and women around the world. It has been suggested that the heparan sulfate constitute the main receptor recognized by HPV, however its role during the interactions with other HPV is not very clear. BC, DE, EF, FG, and HI are the five loops displayed on the surface of the pentamer which can interact with heparin as an analogue for heparan sulfate. In this study, the L1 late protein of ten high risks HPV (HR HPV L1 corresponding to the types 31/33/35/39/45/51/52/56/58/59 were analyzed using in silico methods by looking for insights related to HR HPV L1-loops and heparin interactions. The five loop regions (BC, DE, EF, FG and HI of the ten HR HPV L1 interact with heparin, where the interaction established between the BC-loop and heparin was found to be present in all the HR HPV L1 analyzed in this study as well as those reported in the scientist literature. Moreover it was found that lysine residues are involves in most of interactions and that the chargecharge and polar interactions are stabilizing the HR HPV L1-heparin interaction. The results obtained in this work with all the in silico methods; suggest that the heparin-binding site in the loops for all the HR HPV plays an important role during HR HPV infections, where BC-loop constitute the most required structure during the HR HPV L1-heparin interactions. The charge-charge and polar interactions are the main forces stabilizing the HR HPV L1-heparin.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    The etiology of congenital scoliosis and its development remains unclear and has not yet been fully identified, even there are theories that congenital scoliosis could be derived from the failure of formation or failure of segmentation, which are etiologically heterogeneous with genetic, epigenetic, and environmental factors contributing to their occurrence. We reported a case of long-term follow-up after posterior vertebral column resection (PVCR) in both identical twins with similar congenital kyphoscoliosis at thoracolumbar levels. Twin I had been noticed by his parents to have asymmetry of his back at age 5 years, but no treatment was given. Twin II was first noticed to have a spinal problem at 11 years of age by his parents. Overtime, spine of both twins became further deviated to the left with kyphosis and was referred to our hospital. Both monozygotic twins were treated by PVCR and satisfactory results were demonstrated at 10-year follow-up.This case is the first report on the surgical treatment with PVCR, almost simultaneously, in both identical twins who had similar congenital vertebral anomalies causing kyphoscoliosis. Both identical twins with congenital kyphoscoliosis had undergone surgical correction by PVCR, anterior support with a mesh cage and posterior fusion using pedicle screws at the age of 14 years and achieved a satisfactory correction and a stable spine without curve progression with 10-year follow-up.

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

  2. The ten thousand Kims

    In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that for married women entering a collection of family books in a certain year, the occurrence of the most common family name 'Kim' should be directly proportional to the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to a high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to the year 500 AD, based on the RGF model, and find about ten thousand Kims.

    We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study [1], an alternative account in the framework of (non abstractive) episodic models of memory [4].

  7. Geothermal Exploration Case Studies on OpenEI (Presentation)

    Young, K.; Bennett, M.; Atkins, D.

    2014-03-01

    The U.S. Geological Survey (USGS) resource assessment (Williams et al., 2008) outlined a mean 30 GWe of undiscovered hydrothermal resource in the western United States. One goal of the U.S. Department of Energy's (DOE) Geothermal Technology Office (GTO) is to accelerate the development of this undiscovered resource. DOE has focused efforts on helping industry identify hidden geothermal resources to increase geothermal capacity in the near term. Increased exploration activity will produce more prospects, more discoveries, and more readily developable resources. Detailed exploration case studies akin to those found in oil and gas (e.g. Beaumont and Foster, 1990-1992) will give developers central location for information gives models for identifying new geothermal areas, and guide efficient exploration and development of these areas. To support this effort, the National Renewable Energy Laboratory (NREL) has been working with GTO to develop a template for geothermal case studies on the Geothermal Gateway on OpenEI. In 2012, the template was developed and tested with two case studies: Raft River Geothermal Area (http://en.openei.org/wiki/Raft_River_Geothermal_Area) and Coso Geothermal Area (http://en.openei.org/wiki/Coso_Geothermal_Area). In 2013, ten additional case studies were completed, and Semantic MediaWiki features were developed to allow for more data and the direct citations of these data. These case studies are now in the process of external peer review. In 2014, NREL is working with universities and industry partners to populate additional case studies on OpenEI. The goal is to provide a large enough data set to start conducting analyses of exploration programs to identify correlations between successful exploration plans for areas with similar geologic occurrence models.

  11. Ten-Year Survival of a Patient Treated with Stereotactic Gamma Knife Radiosurgery for Brain Metastases from Colon Cancer with Ovarian and Lymph Node Metastases: A Case Report

    Nobuhiro Morinaga

    2016-05-01

    Full Text Available Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT/calcium folinate (leucovorin, LV was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

  12. Meteorology drives ambient air quality in a valley: a case of Sukinda chromite mine, one among the ten most polluted areas in the world.

    2016-07-01

    The ambient air quality (AAQ) assessment was undertaken in Sukinda Valley, the chromite hub of India. The possible correlations of meteorological variables with different air quality parameters (PM10, PM2.5, SO2, NO2 and CO) were examined. Being the fourth most polluted area in the globe, Sukinda Valley has always been under attention of researchers, for hexavalent chromium contamination of water. The monitoring was carried out from December 2013 through May 2014 at six strategic locations in the residential and commercial areas around the mining cluster of Sukinda Valley considering the guidelines of Central Pollution Control Board (CPCB). In addition, meteorological parameters viz., temperature, relative humidity, wind speed, wind direction and rainfall, were also monitored. The air quality data were subjected to a general linear model (GLM) coupled with one-way analysis of variance (ANOVA) test for testing the significant difference in the concentration of various parameters among seasons and stations. Further, a two-tailed Pearson's correlation test helped in understanding the influence of meteorological parameters on dispersion of pollutants in the area. All the monitored air quality parameters varied significantly among the monitoring stations suggesting (i) the distance of sampling location to the mine site and other allied activities, (ii) landscape features and topography and (iii) meteorological parameters to be the forcing functions. The area was highly polluted with particulate matters, and in most of the cases, the PM level exceeded the National Ambient Air Quality Standards (NAAQS). The meteorological parameters seemed to play a major role in the dispersion of pollutants around the mine clusters. The role of wind direction, wind speed and temperature was apparent in dispersion of the particulate matters from their source of generation to the surrounding residential and commercial areas of the mine.

    2010-01-01

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

  14. Ten steps or climbing a mountain: A study of Australian health professionals' perceptions of implementing the baby friendly health initiative to protect, promote and support breastfeeding

    Sheehan Athena

    2011-08-01

    Full Text Available Abstract Background The Baby Friendly Hospital (Health Initiative (BFHI is a global initiative aimed at protecting, promoting and supporting breastfeeding and is based on the ten steps to successful breastfeeding. Worldwide, over 20,000 health facilities have attained BFHI accreditation but only 77 Australian hospitals (approximately 23% have received accreditation. Few studies have investigated the factors that facilitate or hinder implementation of BFHI but it is acknowledged this is a major undertaking requiring strategic planning and change management throughout an institution. This paper examines the perceptions of BFHI held by midwives and nurses working in one Area Health Service in NSW, Australia. Methods The study used an interpretive, qualitative approach. A total of 132 health professionals, working across four maternity units, two neonatal intensive care units and related community services, participated in 10 focus groups. Data were analysed using thematic analysis. Results Three main themes were identified: 'Belief and Commitment'; 'Interpreting BFHI' and 'Climbing a Mountain'. Participants considered the BFHI implementation a high priority; an essential set of practices that would have positive benefits for babies and mothers both locally and globally as well as for health professionals. It was considered achievable but would take commitment and hard work to overcome the numerous challenges including a number of organisational constraints. There were, however, differing interpretations of what was required to attain BFHI accreditation with the potential that misinterpretation could hinder implementation. A model described by Greenhalgh and colleagues on adoption of innovation is drawn on to interpret the findings. Conclusion Despite strong support for BFHI, the principles of this global strategy are interpreted differently by health professionals and further education and accurate information is required. It may be that the

    Ma-Zi-Ren-Wan (MZRW) is a classic Chinese formula which has been used to treat human constipation in China for over 2000 years. In order to make good and rational use of this formula in the future, this paper presents the first attempt to track the pharmacokinetic features of MZRW in rat using rapid and sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Ten chemical components of MZRW, namely, rhein, emodin, aloe emodin, hesperidin, naringin, amygdalin, albiflorin, paeoniflorin, magnolol and honokiol, were simultaneously determined in rat plasma after a single oral administration (10g/kg body weight) of MZRW to rats. Geniposide and liquiritin were used as internal standards. The separation was performed on a Waters ACQUITY BEH C18 column (100mm×2.1mm, 1.7μm). The detection was conducted by multiple-reaction monitoring (MRM) in negative ionization mode. Two highest abundant MRM transitions without interference were optimized for each analyte. This method was well validated in terms of linearity, precision, accuracy, recovery, matrix effect and stability. All calibration curves had good linearity (r(2)>0.995) over the concentration range from 3.9 to 125.0ng/mL for emodin, 3.9-500.0ng/mL for amygdalin, 2.0-4000.0ng/mL for naringin and hesperidin, 3.9-2000.0ng/mL for magnolol, 7.8-2000.0ng/mL for rhein and 3.9-4000.0ng/mL for albiflorin, paeoniflorin, aloe emodin and honokiol. The intra-day and inter-day precision (relative standard deviation) was within 15%, the accuracy (relative error) ranged from -13.6% to 15.1%, and the lower limit of quantification in plasma ranged between 2.0ng/mL and 7.8ng/mL. Extraction recovery, matrix effect and stability were satisfactory. The validated method was successfully applied to a pharmacokinetic study of these ten compounds after oral administration of MZRW to rats. The pharmacokinetic parameters of each compound can facilitate clinical studies in the future. PMID:26231677

    1997-12-31

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

  18. A case study of embarrassment.

    Dann, O T

    1977-01-01

    The psychoanalytic references to embarrassment are reviewed. Embarrassment, in the literature, is seen largely as an affect involving exhibitionistic and scopophilic conflicts and defenses against these. A case in which embarrassment was prominent is discussed. Embarrassment in the patient was an ego response which implied an external object for its manifestation. It involved exhibitionistic and scopophilic conflicts and projective defenses, but also operated in ego-gratifying and adaptive ways. Her embarrassment was understood through the analysis of an initial embarrassing dream of nakedness and other dreams and associated material as the defensive out-grouth of repeated exposures to the primal scene. Embarrassment was a resistance to remembering in the analysis, and the primal-scene experiences were partially reconstructed. The analytic situation was, in many ways, a symbolic re-creation of the primal scene, including the patient's response of embarrassment. The development of embarrassment in the patient's childhood was furthered and confirmed by its being an identification with the attitudes of both parents. Finally, some reflections on embarrassment and shame in its various forms are set forth. PMID:560404

    2015-01-01

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

  1. Outage management: A case study

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

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    The study was aimed at reporting a case of a patient who developed Hand-Foot Syndrome (HFS) grade 3 due the use of capecitabine and for which massage was used with aqueous-based moisturizer, aloe vera. The patient's functional capacity was assessed using the ECOG Performance Scale and the lesions were photographed during nursing appointment that occurred at intervals of ten days, totaling forty days of monitoring. There was significant improvement in tissue integrity, with total regression of symptoms, an important gain in quality of life, and immediate return to chemotherapy. It is believed that aloe vera can be an important component in nursing care in patients undergoing cancer chemotherapy. PMID:22911424

    Full Text Available The current study described a single child’s language acquisition. The importance of this study resided in the circumstances and the environment in which the child lived. He came from a family in which the parents were from different countries and cultures; spoke different Arabic dialects and who lived in a country in which English is spoken. The child was in his critical period of language acquisition. He seemed to have established a unique way of communicating with people surrounding him to cope with all the linguistic varieties around him. The study showed that the child had semantic, syntactic and morphological overgeneralized structures. The data and results showed that overgeneralization and language acquisition were primarily an innate faculty of the human mind and that imitation did played a primary role in language acquisition.It showed, nevertheless, that imitation and behaviorist approaches could not fully account for language acquisition nor did the generative approach. The results went in favor of an Emergentist approach of language acquisition where both innateness and imitations were crucial constituents of children’s acquisition of linguistic forms.

    Full Text Available This research reviews the literature on case study as a strategic qualitative research methodology. Although case studies have been criticised by some authors as lacking scientific rigour and do not address generalizability, this research, however, reiterated its appropriateness when dealing with a process or a complex real-life activities in great-depth. Case study has been commonly used in social science fields like sociology, industrial relations and anthropology eventhough generally was considered an underutilized strategy. Hence, this research explained the general concept of a case study, strengths and weaknesses of using this method knowing that theoretically case is exciting and data rich. Based on a study of four organizations and the researcher’s own experience, this article described matters on how case study was undertaken, gaining excess to those organizations and the systematic process of data collection and triangulation (multiple techniques. It was noted that combining multiple techniques for elicitng data in case study research actually strengthens and confirmed results.
