Frictional amyloidosis in Oman - A study of ten cases  

Directory of Open Access Journals (Sweden)

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.

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

Energy Technology Data Exchange (ETDEWEB)

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.

But it does not lessen the importance of STD control, because syphilis is still prevalent (8% with congenital syphilis. Peak in the incidence of chancroid (15% is alarming as this may lead to increased transmission of HIV infection in near future. Male unmarried constituted the bulk of STD sufferers (44% and married males (34%, while female unmarried and married patients were 1% and 20% respectively, 5.7% of antenatal mothers were strongly seroreactive for syphilis. Therefore all antenatal mothers should be screened for STD and routine serological test for syphilis should be done.

Insulinoma--clinical experience in ten cases.  

Science.gov (United States)

During the period between January 1981 and December 1992, a total of ten patients with pathologically confirmed insulinoma were studied. All patients presented with variable degrees of neuroglycopenic symptoms and Whipple's triad. The ratio of insulin to glucose after an overnight fast was greater than 0.3 in 90% (9/10) of patients. Eight patients who received supervised fasting developed neuroglycopenia with relative hyperinsulinemia within 48 hours of fasting. Four of 8 patients developed hypoglycemia during a 5-hour oral glucose tolerance test (OGTT). Calcium infusion test was more sensitive in patients with an initially higher plasma glucose. The detection rates of various localization studies were 12.5% (1/8) by abdominal ultrasonography, 37.5% (3/8) by abdominal CT scan, 50% (5/10) by selective superior mesenteric and celiac arteriography. Transhepatic portal venous sampling (THPVS) detected insulinomas in 4 of 4 cases. Endoscopic ultrasonography and intraoperative ultrasonography were performed on 1 and 2 cases respectively, and were able to localize the lesions successfully. All patients received surgical treatment including enucleation (n = 2), subtotal pancreatectomy (n = 3) and distal pancreatectomy (n = 5). All patients had single tumors which were all benign islet cell adenomas. The mean size of the tumors was 15.5 +/- 2.0 mm in diameter (range: 8 to 30 mm) and mainly located in the body (50%) and tail (40%), only 1 in the pancreatic head. All symptoms of hypoglycemia subsided after operation. Hyperglycemia was observed in all patients immediately after operation, and most of them resumed normoglycemia within 8 days. However, the 2 patients who had impaired OGTT preoperatively had persistent hyperglycemia after operation and therefore were diagnosed as having diabetes (NIDDM). PMID:8205495

Childhood herpes zoster: A clustering of ten cases  

Directory of Open Access Journals (Sweden)

Full Text Available Herpes zoster occurs due to reactivation of the latent varicella zoster virus and is usually a disease of the elderly. Childhood herpes zoster is believed to be rare, though recent studies suggest increasing incidence in children. Here we report ten cases of childhood herpes zoster, seven of which occurred within a short span of six months, at a tertiary care level hospital in Pokhara, Nepal. Only three of the ten children reported previous history of varicella infection and none was immunized against varicella. Though childhood herpes zoster accounted for less than 1% of the total zoster cases in the past, recent reports show an increase in the number of cases in apparently healthy children. So far, no studies have been done linking childhood herpes zoster with HIV, though there are many studies linking it with other immunocompromised conditions.

Science.gov (United States)

OBJECTIVES: Considering that the brain abscess is rare in infants, with a high mortality rate, the objective of this paper is to report the clinical evolution of ten children with the diagnosis of brain abscess in the Pediatric Nursery of the Hospital das Clínicas of the Medical School of the Campinas State University (UNICAMP).METHODS: The data of the patients with diagnosis of brain abscess recorded between January 1986 and July 1995 were reviewed. The following data were analyzed: age, sex, clinical manifestations, physical examination, radiological data, etiological agent, treatment, complications and clinical evolution of the patients.RESULTS: The age of the patients varied from 2 to 13 years (median 3 years); 6 of them were female. The neurological manifestations predominated, and 2 patients had history of prior otorhinolaryngological infection (chronic otitis media and sinusitis). Two patients had congenital cyanogenic cardiopathy (Fallot tetralogy and Pulmonary Stenosis with Interventricular Communication). The diagnosis and follow-up were made with computed tomography of the brain. In six cases there were one sole abscess located more frequently in the frontal lobe. The treatment in majority of the cases was broad-spectrum antibiotic association and surgical drainage. Five patients had neurological sequelae (seizure, hydrocephalus and paresis); one death occurred.CONCLUSIONS: Although rare, the brain abscess has to be remembered in patients that have neurological alterations associated to risk factors, as otorhinolaryngological infections and congenital cyanotic cardiopathy, being mandatory the realization of computed tomography of the brain to confirm the diagnosis.

Simulation Study of TenTen: A new Multi-TeV IACT array  

CERN Document Server

TenTen is a proposed array of Imaging Atmospheric Cherenkov Telescopes (IACT) optimized for the gamma ray energy regime of 10 TeV to 100 TeV, but with a threshold of ~1 to a few TeV. It will offer a collecting area of 10 km2 above energies of 10 TeV. In the initial phase, a cell of 3 to 5 modest-sized telescopes, each with 10-30 m2 mirror area, is suggested for an Australian site. A possible expansion of the array could comprise many such cells. Here we present work on configuration and technical issues from our simulation studies of the array. Working topics include array layout, telescope size and optics, camera field of view, telescope trigger system, electronics, and site surveys.

Ten cases of sebaceous carcinoma arising in nevus sebaceus.  

Science.gov (United States)

Although nevus sebaceus is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only 14 cases of secondary sebaceous carcinoma have been reported. In this study, 10 cases of sebaceous carcinoma arising in nevus sebaceus were collected. The clinicopathological features and results of immunohistochemical examinations with adipophilin, perilipin and p53 were summarized. Sebaceous carcinoma arising in nevus sebaceous predominantly occurred on the scalp (8/10) of elderly women (mean age, 67.7 years). No case was associated with Muir-Torre syndrome. We found several pathological features of sebaceous carcinoma; that is, made up mainly of germinative cells, moderate nuclear atypia without pleomorphism and many mitoses (4-28/10 high-power field). Adipophilin and perilipin antibodies highlighted lipid drops in the cytoplasm of the malignant cells in all cases. Overexpression of p53 was seen in all cases. In two cases there were coexisting benign-looking sebaceous lesions at the periphery of the main cancer nodule, and in these lesions p53 showed low positivity compared with the clearly malignant area. There was co-occurrence of another neoplasm in three cases with trichoblastoma, sebaceoma and syringocystadenoma papilliferum, respectively. All cases were treated by excision of the malignant lesion, with or without inclusion of the nevus sebaceus. In a follow-up period of 1-7 years, there was no case of recurrence, lymph node metastases or distant metastases. With these specific pathological and immunohistochemical findings using adipophilin, perilipin and p53, we have to consider the possibility that there is a tendency to underdiagnose secondary sebaceous carcinomas in nevus sebaceus. These clinicopathological features of sebaceous carcinomas developing in the nevus sebaceus seem to indicate different biological entities from de novo sebaceous carcinoma. PMID:19120764

Proliferative verrucous leukoplakia: a report of ten cases.  

Science.gov (United States)

A particularly aggressive form of oral leukoplakia that commences with a hyperkeratosis, spreads to become multifocal and verruciform in appearance, and later becomes malignant has been termed proliferative verrucous leukoplakia. Ten patients with persistent multifocal verruciform white patches were investigated. Lesions were often bilateral and affected predominantly mandibular alveolar and buccal mucosa. At first biopsy no lesion was graded higher than a verrucous hyperplasia, but subsequently all patients had squamous cell carcinoma, and two patients have died of their disease. Lesions were managed with surgery, carbon dioxide laser, and photodynamic therapy. The patients presented here confirm the existence of proliferative verrucous leukoplakia as a clinicopathologic entity. Careful examination of the whole mouth is essential when a hyperplastic white patch is seen to check for possible proliferative verrucous leukoplakia. Early aggressive treatment must then be started, and regular long-term review is crucial. PMID:8899776

Pulmonary Lymphangioleiomyomatosis: A Clinicopathological Analysis of Ten Cases.  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Lymphangioleiomyomatosis (LAM of the lung is a very rare disease ofunknown etiology which occurs particularly in women of childbearing age.So far, there have been very few reports of LAM in Taiwan.Methods: Data on all patients with a clinical or pathological diagnosis of LAM inChang Gung Memorial Hospital from 1990 to 2001 were collected from thepathology files or by consultation with thoracic surgeons, chest physicians,and radiologists of this institution. Cases were confirmed by lung biopsy andhigh-resolution computed tomographic scanning. Clinical data were obtainedfrom patients' charts. Additional immunostaining for HMB-45 antigen, estrogenreceptor, and progesterone receptor was carried out for cases with availableparaffin blocks.Results: In total, 10 patients confirmed with a diagnosis of LAM and adequate clinicalfollow-up information were found from 1991 to 2001. All were femalesof fertility age. The follow-up periods ranged from 18 to 167 months. Sixpatients received hormonal therapy. According to the pulmonary functiontests and clinical symptoms, 6 patients were in stable condition and 4 showedslow progression of disease by the time of the last follow-up. Two patientsdied after lung transplantation and abdominal surgery for retroperitonealLAM, respectively, at another medical center.Conclusions: The clinicopathological features of our series are similar to those reportedfrom other countries. The clinical course was slowly progressive with no significantresponse to hormonal therapy. Lung biopsies are important for adiagnosis, but the size and location of the biopsy specimens greatly affect thediagnostic reliability.

Hemicrania continua: a report of ten new cases  

Directory of Open Access Journals (Sweden)

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.

The authors concluded that: 1 the lesion in children with tuberculosis of the CNS is generally a proliferative meningoencephalitis; 2 the nervous parenchyma may be affected by the contiguous propagation of the tuberculous process or by the circulatory changes secondary to the arterial lesions; 3 because of the localization of the endocranial vessels in the sub-arachnoidal space they are generally injured by the inflammatory process, which can determine an obliterating endarteritis, which can be observed by a carotid angiography.

Primary localized conjunctival amyloidosis: A case report with a ten-year follow-up period  

Directory of Open Access Journals (Sweden)

Full Text Available Juan Carlos Mesa-Gutiérrez, Tomás Martí Huguet, Noemí Barnils Garcia, Jorge Arruga GinebredaDepartment of Ophthalmology, Hospital Universitari de Bellvitge, L’Hospitalet de Llobregat, Barcelona, SpainAbstract: A 57-year-old woman consulted our department about a plaque that had been present in her left eye for one year. Ophthalmological examination revealed a solid mass in the left conjunctival semilunar fold. An excitional biopsy was peformed, revealing an amyloid deposition. The patient was referred to the Internal Medicine Department for systemic study. All studies were negative for systemic amyloidosis. Throughout ten years of follow-up study, the patient has shown neither conjunctival recurrence nor any evidence of systemic amylodosis. Despite the fact that several authors have described ocular amyloidosis as an ophthalmologic manifestation of systemic amyloidosis, conjunctival location of amyloidosis is a very rare condition. Amyloid characterization in ocular structures should not be considered a final diagnosis since involvement of systemic underlying diseases must be ruled out. We report a case of localized conjunctival amyloidosis with a ten-year follow-up period that excluded ocular or systemic diseases.Keywords: conjuctival amyloidosis, ocular amyloidosis, hyaline protein

Ten tools of continuous quality improvement: a review and case example of hospital discharge.  

Science.gov (United States)

Concepts and methods of continuous quality improvement have been endorsed by quality specialists in American Health care, and their use has convinced CEOs that industrial methods can make a contribution to health and medical care. For all the quality improvement publications, there are still few that offer a clear, concise definition and an explanation of the primary tools for teaching purposes. This report reviews ten continuous quality improvement methods including: problem solving cycle, affinity diagrams, cause and effect diagrams, Pareto diagrams, histograms, bar charts, control charts, scatter diagrams, checklists, and a process decision program chart. These do not represent an exhaustive list, but a set of commonly used tools. They are applied to a case study of bed utilization in a university hospital. PMID:8547801

Fine needle aspiration cytology of primary thyroid lymphoma: a report of ten cases  

Directory of Open Access Journals (Sweden)

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.

Spontaneous Mediastinitis in a Ten-year-old Girl: A Case Report  

Energy Technology Data Exchange (ETDEWEB)

Acute suppurative mediastinitis is an uncommon, life threatening condition with a mortality rate of up to 40%. It is mainly caused by esophageal perforation or post-operative complications, and acute mediastinitis not caused by trauma or surgery is rare. To the best of our knowledge, no cases of spontaneous mediastinal abscess in children have been reported in the English medical literature. We report here on a case of an acute mediastinal abscess in a ten-year-old girl and there was no demonstrable clinical or radiologic etiology for infection

A retrospective study of the pattern of sexually transmitted diseases during a ten-year period  

Directory of Open Access Journals (Sweden)

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

Temperament and character in eating disorders: ten years of studies.  

Science.gov (United States)

In recent years a number of studies of personality have been performed in subjects with Eating Disorders (EDs) to investigate the clinical differences between controls and ED patients and among EDs subtypes, and its role in the development and course of symptoms. The Tridimensional Personality Questionnaire (TPQ) and the Temperament and Character Inventory (TCI) have been widely used at this purpose, allowing the description of specific temperament and character profiles for EDs. High Harm Avoidance (HA) and low Self-Directedness (SD) are shared by all EDs. Slight differences on some facets have been found among ED subgroups. Nevertheless, HA is influenced by mood and both high HA and low SD are personality traits shared by many mental disorders, whose specificity is rather low. Restrictor anorectics are characterized by high Persistence (P) and a relatively higher SD, and bulimics by higher Novelty Seeking (NS) and the lowest SD, while binge/purging and purging anorectics share some traits with anorexia and some with bulimia. Though current data justify the discrimination among anorexia subtypes, they are not in contrast with the thesis of a continuum in ED personality traits. Since some personality traits display a prognostic value with regard to therapy and clinical outcome, further studies are needed on treatments and prognostic factors in EDs. Moreover, studies attempting to define the neurobiological and genetic correlates of temperament should be supported by clinical pharmacological trials. PMID:15330074

The Gestational Trophoblastic Diseases: A Ten Year Retrospective Study  

Directory of Open Access Journals (Sweden)

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.

Ten years of Developing International Volcanology Graduate Study Programs  

Science.gov (United States)

In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by coursework and research networks. Because the international developments of volcanology programs address the need for more robust coursework and research choices for students than are possible on one campus, and because they lead to a diverse network of professional contacts , we think the next decade will bring many more multi-university volcanology programs linked to field sites all over the world.

Casing study  

Energy Technology Data Exchange (ETDEWEB)

An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

Prognostic factors in children with acute lymphoblastic leukemia: a ten year study  

Directory of Open Access Journals (Sweden)

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.

Ten years of BSE surveillance in Italy: neuropathological findings in clinically suspected cases.  

Science.gov (United States)

Between 2001 and 2010, 244 clinically suspected cases of bovine spongiform encephalopathy (BSE) were reported in Italy. This report summarizes the neuropathological findings in cattle displaying clinical signs consistent with a diagnosis of BSE. All animal specimens were submitted for confirmatory testing; samples testing negative underwent neuropathological examination to establish the differential diagnosis. Immunohistochemistry for scrapie prion protein (PrPSc) at the level of frontal cortex was carried out to exclude atypical BSE. Neuropathological changes were detected in 34.9% of cases; no histological lesions were found in 52.3% of subjects; 12.8% of samples were found unsuitable for analysis. BSE was detected in one case, but no cases of atypical BSE were observed. This study identified the diseases most commonly encountered in the differential diagnosis of BSE; furthermore, it demonstrated that the surveillance system is necessary for monitoring neuropathological disease in cattle and for the detection of BSE cases.

[Why should an abdominal CT scan be performed for suspected appendicitis in the adult patient? Lessons from ten clinical cases].  

Science.gov (United States)

Ten years after its introduction, the contribution and indications for computed tomography (CT) in the diagnosis of appendicitis remain the subject of controversy among surgeons. Many argue that CT is frequently superfluous and costly, results in excessive radiation exposure, and delays surgical treatment. On our service, we perform 150 to 180 adult appendectomies annually. We feel that CT helps us to avoid unnecessary appendectomy, to clear up diagnostic uncertainty, and, most importantly, to guide the choice of surgical approach. We illustrate our experience through ten clinical cases in which the use of preoperative imaging has resulted in improved care. PMID:19850295

International Nuclear Information System (INIS)

Objective: To investigate the clinical effect of permanent 125I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

Purple urine bag syndrome in nursing homes: ten elderly case reports and a literature review.  

Science.gov (United States)

Purple urine bag syndrome (PUBS) is a rare occurrence, in which the patient has a purple-colored urine bag following urinary catheterization for hours to days. 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.

Acute cerebellitis in varicella: a ten year case series and systematic review of the literature  

Science.gov (United States)

Background Acute cerebellitis (AC) is the most common neurological complication of varicella. Nevertheless, it has been scarcely studied. The objective of this study were to asses the occurrence of AC among children hospitalized for varicella and to analyze its specific clinical picture and outcome. Methods We retrospectively reviewed the medical records of children admitted to the hospital for varicella between 1st October 2003 and 1st June 2013 and we compared our results with literature. Children were all unvaccinated for varicella. Results In our case series, AC was found out in 48 out of 457 patients (10.5%). The highest frequency of AC was observed in children from 1 to 5 years of age (60.9%). The most characteristic symptom of AC was a broad-based gait disturbance that progressed gradually over the course of a few days (95.8%). Other common symptoms included slurred speech (37.5%), vomiting (31.25%), headache (29.16%), dysmetry (25%) and tremor (22.91%). After a long hospitalization (median of 11 days), all but one children were dismissed without invalidating sequelae. Conclusions Data from this study may help to better address the problem of varicella cerebellar complications in hospitalized children and to monitor changes over time caused by an increase in vaccination coverage.

Analysis of the p53 gene by PCR-SSCP in ten cases of Wilms’ tumor  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese CONTEXTO: Mutações do gene supressor tumoral p53 são observadas como as mais freqüentes alterações em neoplasias humanas em adultos. Em oncologia pediátrica, entretanto, são pouco identificadas. O tumor de Wilms é uma neoplasia renal comum em crianças e associa-se com mutações do gene WT1. A correla [...] ção entre tumor de Wilms e alterações do gene p53 não está bem estabelecida, sendo baixa a freqüência tumoral, podendo haver associação com doença em estágio avançado e histologia desfavorável. TIPO DE ESTUDO: Relato de caso. RELATO DE CASO: Foi realizar uma triagem para mutações do gene p53 pelo método de PCR-SSCP e seqüenciamento de DNA nos casos sugestivos de mutação em tumor de Wilms. Avaliação do gene p53 nos exons 5-9 em amostras de DNA extraídos de 10 tumores de Wilms de crianças em diferentes estágios pelo método de PCR-SSCP e seqüenciamento de DNA. Alterações na análise do SSCP foram observadas em duas amostras no exon 8. As prováveis mutações não foram confirmadas pelo seqüenciamento de DNA. A ausência de mutações de ponto do gene p53 observada nas 10 amostras de tumor de Wilms estudadas está de acordo com a literatura, sendo o seqüenciamento de DNA fundamental para a confirmação de possíveis mutações. Abstract in english CONTEXT: Mutations of the p53 tumor suppressor gene are the most frequent alterations observed in human neoplasias affecting adults. In pediatric oncology, however, they have seldom been identified. Wilms’ tumor is a renal neoplasia commonly occurring in children and is associated with mutations of [...] the WT1 gene. The correlation between Wilms’ tumor and alterations of the p53 gene has not been well established, with a low frequency of mutations having been reported in this type of tumor. Mutation may be associated with advanced stage disease and unfavorable histology. OBJECTIVE: To screen for mutations of the p53 gene by the PCR-SSCP method and DNA sequencing in cases of Wilms’ tumor sug-gestive of mutation. DESIGN: Case Report. CASE REPORT: Evaluations of exons 5-9 of the p53 gene in DNA samples extracted by PCR-SSCP from 10 Wilms’ tumors in children at different stages, and DNA sequencing. Changes in SSCP analy-sis were observed in exon 8 in two samples. The probable muta-tions were not confirmed by DNA sequencing. The absence of point mutations in p53 gene observed in the 10 samples of Wilms’ tumor studied agrees with literature data, with DNA sequencing being of fundamental importance for the confirmation of possible mutations.

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/phosphatase, nosocomial catheter-associated UTIs

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

Science.gov (United States)

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

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To analyze data of cases with lung cancer (LC diagnosed in our clinic over one year period and compare them with data of cases with LC diagnosed before ten years. Method: The demographic data, radiological and bronchoscopic findings, diagnostic methods, and histological type and stages of the patients diagnosed with lung cancer in year 2005 were evaluated. Results: Over one year period, 138 patients were diagnosed with LC. 104 (75.4% were men and 34 (24.6% were women. Mean age was 63.78±9.53 (38-83. 118 (86.5% of the patients had 39±16.34 (5-90 pack-years smoking history. Squamous cell carcinoma (SCC was diagnosed in 40.6% of patients, adenocarcinoma in 29.0%, small cell carcinoma in 21.0%, conbined type in 8.0% and carcinoma with unidentified cell type in 1.4%. Squamous cell carcinoma was more common among smoking patients. It was determined that the distribution of histological types in this study was similar to the previous studies, however the incidence of LC was found as increased in females in our study when compared to previous studies. Conclusion: We conclude that SCC is the most common histological type in patients with LC in our clinic and the male to female ratio for LC is decreasing.

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

Directory of Open Access Journals (Sweden)

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.

Full Text Available The aim of this study was to assess ten plants from the Congolese pharmacopoeia for their analgesic activity as well as their cytotoxicity, in order to validate their traditional use. Thirty-three extracts were obtained in 3 different solvents (Water, Ethanol, DCM from these ten plants selected after an ethnobotanic survey in the region of the Pool (Congo Brazzaville: Leonotis nepetaefolia (Lamiaceae, Manotes pruinosa (Connaraceae, Spilanthes uliginosa (Asteraceae, Hymenocardia ulmoides (Euphorbiaceae, Celosia trigyna (Amaranthaceae, Cogniauxia podolaena (Cucurbitaceae, Brillantaisia patula (Acanthaceae, Urena lobata (Malvaceae , Mitracarpus scaber (Rubiaceae, Triumfetta rhomboidea (Tiliaceae. The writhing test (Siegmund Chemical Test was used for the pharmacological screening. The cytotoxicity of all the extracts was tested on KB (Human epidermoid carcinoma and Vero (African green monkey kidney cell lines with taxotere as positive control. A TLC chemical screening of the extracts was carried out to detect the major chemical classes present in the plants. The data of the traditional medicine were confirmed, since eight plants out of ten were active, aqueous and ethanolic extracts being the most active. Moreover, only C. podolaena leaf extracts were cytotoxic (87% of inhibition on KB. This work opens the way for the research of the active molecules from these plants and for their use as leads in the synthesis and the pharmacomodulation of compounds with analgesic potentiality.

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Suppression of immune system in treated cancer patients may lead to secondary infections that obviate the need of antibiotics. In the present study, an attempt was made to understand the occurrence of secondary infections in immuno-suppressed patients along with herbal control of these infections with the following objectives to: (a isolate the microbial species from the treated oral cancer patients along with the estimation of absolute neutrophile counts of patients (b assess the in vitro antimicrobial activity medicinal plants against the above clinical isolates. Methods Blood and oral swab cultures were taken from 40 oral cancer patients undergoing treatment in the radiotherapy unit of Regional Cancer Institute, Pt. B.D.S. Health University, Rohtak, Haryana. Clinical isolates were identified by following general microbiological, staining and biochemical methods. The absolute neutrophile counts were done by following the standard methods. The medicinal plants selected for antimicrobial activity analysis were Asphodelus tenuifolius Cav., Asparagus racemosus Willd., Balanites aegyptiaca L., Cestrum diurnum L., Cordia dichotoma G. Forst, Eclipta alba L., Murraya koenigii (L. Spreng. , Pedalium murex L., Ricinus communis L. and Trigonella foenum graecum L. The antimicrobial efficacy of medicinal plants was evaluated by modified Kirby-Bauer disc diffusion method. MIC and MFC were investigated by serial two fold microbroth dilution method. Results Prevalent bacterial pathogens isolated were Staphylococcus aureus (23.2%, Escherichia coli (15.62%, Staphylococcus epidermidis (12.5%, Pseudomonas aeruginosa (9.37%, Klebsiella pneumonia (7.81%, Proteus mirabilis (3.6%, Proteus vulgaris (4.2% and the fungal pathogens were Candida albicans (14.6%, Aspergillus fumigatus (9.37%. Out of 40 cases, 35 (87.5% were observed as neutropenic. Eight medicinal plants (A. tenuifolius, A. racemosus, B. aegyptiaca, E. alba, M. koenigii, P. murex R. communis and T. foenum graecum showed significant antimicrobial activity (P P. aeruginosa was observed highest susceptible bacteria (46.6% on the basis of susceptible index.

The clinical and imaging features of clear cell meningioma in ten cases  

Directory of Open Access Journals (Sweden)

Full Text Available Objective To investigate the clinical features and imaging findings of intracranial clear cell meningioma. Methods The clinical data were reviewed, including presentation, imaging and prognosis of 10 patients suffered from intracranial clear cell meningioma for 2 months-7 years and underwent surgical treatment. The patients included five males and five females with the age from nine to sixty-two years old (mean 35.43. The tumors were located at cerebellopontine angle (CPA zone (n = 5, parietal lobe (n = 1, tuberculum sella (n = 1, jugular foramen (n = 1, tentorium of cerebellum (n = 1 or lateral cerebral ventricle (n = 1. The initial symptoms included headache (n = 4, gait disturbance (n = 2, hearing loss (n = 2, vision loss (n = 1 and bucking (n = 1 which were associated with the mass locations. Results CT (n = 8 and MRI (n = 10 of 10 patients were retrospectively reviewed. CT findings of the lesions presented with hyperdensity (n = 6, isodensity (n = 1, or isodensity with hyperdensity (n = 1. MRI T1WI showed isointensity (n = 4, hypointensity with isointensity (n = 4 or hyperintensity (n = 2, whereas T2WI isointensity with hyperintensity (n = 7, presented hypointensity (n = 1, isointensity (n = 1, or hyperintensity (n = 1. On gadolinium-enhanced T1WI, moderate enhancement was seen in 8 lesions and marked enhancement was seen in 2 lesions. In initial CT scanning peritumoral edema was found in 7 cases, dural tail sign in 5 cases, cysts in 7 cases, calcification in 3 cases, periosteal proliferation in 1 case and bone destruction in 5 cases. Seven patients underwent complete resection and 3 underwent subtotal resection. Follow-up period was 11-120 months. Recurrence occurred in 5 patients. The mean recurrence time was 55.62 months. Conclusion Clear cell meningioma is a rare meningioma and often occurs in young persons without significant difference in sex. The CPA zone is the most affected area. The prognosis is closely related to the extent of resection. Clear cell meningioma tends to present marked enhancement, peritumoral edema, cystic components, and bone involvement in imaging findings?

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

International Nuclear Information System (INIS)

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.

Dirofilaria repens infection in a ten-year-old boy from the Istria Peninsula: case report.  

Science.gov (United States)

Dirofilariasis is a zoonotic infection caused by worms belonging to the genus Dirofilaria. The disease is transmitted by mosquitoes and the hosts are usually dogs. Infections in humans are rare and they usually manifest as a subcutaneous nodule or a conjunctival form. We present a 10-year-old boy with a subcutaneous nodule on his left forearm, who was admitted to the hospital. On examination, the only significant findings were high levels of eosinophils. The pediatrician suspected dirofilariasis and the boy was referred to pediatric surgery. The whole lesion was surgically removed and histopathologic examination confirmed parasitic infection by Dirofilaria repens. Although human dirofilariasis is a rare disease, the number of reported cases has recently increased worldwide. The disease mainly occurs in southern European countries, but has also been described in eastern Europe, Central Asia and Sri Lanka. Croatia is one of the endemic areas for dirofilariasis, especially in the region of the Istria Peninsula. The case presented highlights the requirement for further monitoring of endemic areas in order to establish effective preventive measures. PMID:24697007

Flouride. Ten-year prospective study of deciduous and permanent dentition.  

Science.gov (United States)

A ten-year longitudinal prospective study compared the effect of fluoride on dentition of 1,500 children from infancy through age 10 years. In Kalamazoo, Mich, and Oneida, NY, parallel groups were given a fluoride-vitamin supplement from infancy and from age 4 and compared with fluoridated water and control groups. Incidence of new caries activity in both deciduous and permanent teeth was measured by mean number of new decayed and filled teeth, as well as percentage of children with no caries throughout the periods studied. Prevalence of caries was also studied in six-year molars. The results indicate a consistent (and, for selected groups, a statistically significant) diminution in caries activity for both deciduous and permanent teeth for groups ranked from greatest retardation of caries to least: infant fluoride group, water fluoride group, age 4 fluoride group, and controls.

Ipsilateral combination of Galeazzi and Monteggia fractures in a ten-year-old patient: a case report.  

Science.gov (United States)

Galeazzi fractures represent approximately 3 to 6 percent of forearm fractures, whereas Monteggia fractures represent 1 to 2 percent. The combination of these injuries in the same extremity is an exceedingly rare occurrence. We report a case of ipsilateral combination of Galeazzi and Monteggia fractures in a ten-year-old patient. The patient was treated with closed reduction and internal fixation with Kirschner pins. The distal radioulnar and radiocapitellar joint relationships were restored and the fractures healed. The patient proceeded to obtain a satisfactory functional result three years later. Internal fixation is a safe method for such complex forearm fractures in older children and allows post-operative rehabilitation with the advantage of early mobilization. PMID:21057152

Medical School Attrition-Beyond the Statistics A Ten Year Retrospective Study  

Directory of Open Access Journals (Sweden)

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 medical schools have a duty of care to support students who leave the medical programme.

[Entomological investigations conducted around ten cases of yellow fever in 2009 in the Denguélé sanitary region, Côte-d'Ivoire].  

Science.gov (United States)

In November 2009, ten suspicious cases of yellow fever, including six deaths, were notified in the region of Denguélé, in the northwest of Côte-d'Ivoire. In order to evaluate the extent of yellow fever virus circulation and the risk for local people, a mission of entomological investigation was carried out by the Ministry of Health and Public Hygiene of Côte-d'Ivoire. Entomological investigations were conducted in the villages of confirmed cases (Banakoro and Tron-Touba) and the centers of consultation and hospitalization of cases during illness. Breteau index and recipient index were quasi nil. Aedes aegypti was absent among the captured mosquitoes. On the other hand, Aedes luteocephalus and Aedes opok were present at Banakoro and Tron-Touba with respective average biting rates of 0.8 and 0.6 bite/man/twilight. This situation of epidemic in the northwest of Côte-d'Ivoire could be explained by the deterioration of Denguélé region's health system which is a consequence of the war started in the country in 2002 and which has lowered the immunity of the population.

Study on phosphorus loadings in ten natural and agricultural watersheds in subtropical region of China.  

Science.gov (United States)

Water eutrophication in subtropical regions of southern China threatens watershed health and is of major concern. However, annual phosphorus (P) loading and its dominant causes are still unclear, especially at the watershed scale. In this study, we investigated dynamic P loadings and associated factors (e.g., land use, livestock production, and runoff depth) in ten watersheds that varied in area from 9 to 5,212 ha in a hilly area of Hunan Province, China. A flowmeter was installed at the outlet of each watershed, and total P (TP) and soluble P (SP) concentrations were monitored periodically from June 2010 to October 2012. The results showed that annual P loadings (APLs) in the ten watersheds ranged from 22.8 to 247.8 kg P/km(2) and that P loss primarily occurred from April to June of each year during the main rainfall season in the study area. In addition, the average eutrophication (>0.05 mg P/L) ratio for stream waters was 86.7 % during the study period, which was indicative of a potentially serious condition for the local water environments. Annual P loadings were linearly related to livestock density (LD; R = 0.92, p < 0.01), whereas the eutrophication ratio of stream water was significantly (p < 0.05) correlated with LD (R = 0.61), percentage cropland (R = 0.71), and percentage forest cover (R = -0.68). Thus, it is concluded that the control of livestock production has the greatest potential for reducing P loadings in watersheds in this subtropical area. This will be beneficial to the amelioration and protection of local environment. PMID:24343709

Results of experimental radiobiological studies made within ten-kilometer zone of Chernobyl accident  

International Nuclear Information System (INIS)

A study was made of the effect of high radioactive contamination on the animal organism (C57BL/6 mice) and Hela cell culture within the ten-kilometer zone of the Chernobyl A.P.S. accident. The total radiation dose, as calculated by ?-component, was 0.09 to 2 Gy. A long-term exposure of mice within the zone (cumulative dose of 1.18 to 2 Gy) caused a significant decrease in bone marrow stem potencies and changes in the brain vascular system; subsequent acute exposure of animals increased interferon titres in the serum to a much greater extent than a single acute exposure did. As to Hela cells, irradiation there of with doses of 0.09 to 0.4 Gy during 15-20 postirradiation generations caused a decrease in the proliferative activity, an emergence of cells with micronuclei and of giant cells

Space ten-meter telescope (STMT) - Structural and thermal feasibility study of the primary mirror  

Science.gov (United States)

The structural and thermal behavior of a ten-meter primary mirror for a space optical/near-IR telescope in geosynchronous orbit is studied. The glass-type lightweighted mirror is monolithic, of the double arch type, and is supported at only three points. The computer programs SSPTA (thermal), NASTRAN (finite element), and ACCOS V (optical) are used in sequence to determine the temperature, deformation, and optical performance of the mirror. A mirror temperature of 130 K or less appears to be obtainable by purely passive means. With a fused silica or standard Zerodur blank, thermally-induced deformation is unacceptable and cannot be fully corrected by an active secondary mirror over the desired field. Either active thermal control or a blank of lower thermal expansion coefficient would be required.

Drug prevalence in drowning deaths in Cuyahoga County, Ohio: a ten-year retrospective study.  

Science.gov (United States)

Previous studies have shown that up to 50% of adult drownings are related to the consumption of alcohol. Little information is available in the literature regarding the possible contribution of ethanol and other drugs to drownings. All records of deaths occurring in Cuyahoga County, Ohio, from 1994-2003, in which drowning was listed as the cause of death, were reviewed. Toxicology analysis was performed on cases where specimens were submitted. Review of the 187 cases showed that the majority (78%) of drowning deaths were ruled as accidents, 26 (14%) as suicide, 5 (3%) as homicide, and 11 (6%) as undetermined. Among the accidental deaths (n=141), 97 (69%) were negative for all drugs, including ethanol, and 30 cases (21%) were positive for ethanol only. Illicit drugs were detected in 4 of the cases (3%). In the suicides (n=26), 16 (62%) were negative for all drugs, including ethanol, and 7 cases (27%) were positive for ethanol only (mean blood alcohol concentration [BAC] 0.03 g/dL). Illicit drugs were detected in 3 of the cases (12%). Two of the 5 homicide cases (40%) were positive for ethanol. There were no cases in which the victim tested positive for illicit drugs. Of the 11 cases ruled as undetermined, 64% (n=7) were negative for all drugs, including ethanol. The remainder of the cases tested positive for ethanol only. There were no cases in which illicit drugs were detected. This study demonstrates that the majority of drowning deaths in Cuyahoga County, Ohio, were not drug related. Deaths in which drugs were detected were typically accidental deaths, with ethanol the most common drug detected. PMID:16121079

Use of illicit stimulant drugs in Finland: a wastewater study in ten major cities.  

Science.gov (United States)

Estimations of drug use at the national level are generally based on various sources of information, such as drug seizures, socio-scientific studies, toxicological data and hospital records. Nevertheless, all of these approaches have limitations that cannot be overcome, even if conclusions are drawn from combined data retrieved from different sources. Drug epidemiology through wastewater analysis has the potential to provide unique perspectives, internationally comparable data, and up-to-date information on the use of both traditional illicit drugs and new psychoactive substances (NPSs). In Finland, no large-scale studies on regional illicit drug consumption, based on a wastewater approach, have been reported. In this study, 24-h influent composite samples were collected during two 1-week study periods from ten different wastewater treatment plants in May and November-December 2012. The cities included in the study represent the geographical areas throughout Finland and cover 40% of the Finnish population. The samples were analyzed with an in-house validated, ultra high-performance liquid-chromatography mass spectrometric (UHPLC-MS/MS) method for various common illicit drugs and some NPS type stimulant drugs. The results were also compared with available statistics, information on drug seizures and laboratory-confirmed toxicological data, as well as other studies available based on wastewater analysis. The data show that illicit stimulant drug use is more common in the larger cities of Southern Finland. Amphetamine was the most commonly used drug in all 10 cities during both collection periods (excluding the collection period in May in Lappeenranta). Cocaine consumption remains very low in Finland in comparison to other European countries; it was concentrated in the biggest cities in Southern Finland. This study shows interesting temporal and spatial differences in drug use in Finland, as well as the possibilities of using wastewater analytics to reveal local hotspots of NPS consumption.

Penile cutaneous horn ten years after treatment of verrucous squamous cell carcinoma on penile glans: case report.  

Science.gov (United States)

Penile cutaneous horn is a clinical term that describes protruding hyperkeratosis, usually conical in shape, located on penile glans. Penile localization of this lesion, predominantly located on sun-exposed areas, is very rare. The association with malignancy on the penis makes proper identification of these lesions essential. We present a 45-year-old man with a cutaneous horn, 25 mm in size, located on the basis of penile glans. The patient had a history of phimosis, pseudoepitheliomatous balanoposthitis, surgical excision of penile verrucous squamous cell carcinoma (SCC) and postoperative radiotherapy of carcinoma in situ on the same localization, ten years before. Complete surgical removal of the horn with separate excision of the margins and base was done. Pathologic examination revealed squamous hyperplasia with suspicion of carcinoma in situ. Additional negative p16(INK4a) immunohistochemical analysis confirmed benign proliferative lesion. DNA polymerase chain reaction for human papilloma virus infection was negative. These findings suggested sparing surgical procedure in our patient, without indication for partial penile amputation, but with mandatory follow-up. Our case confirmed the association of pseudoepitheliomatous balanoposthitis with verrucous SCC, as well as the possible influence of radiotherapy on the development of penile cutaneous horn. Additionally, we showed the important role p16(INK4a) immunohistochemical analysis in the differential diagnosis of alterations adjacent to invasive SCC of the penis. PMID:22507472

Prehospital trauma care reduces mortality. Ten-year results from a time-cohort and trauma audit study in Iraq  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Blunt implementation of Western trauma system models is not feasible in low-resource communities with long prehospital transit times. The aims of the study were to evaluate to which extent a low-cost prehospital trauma system reduces trauma deaths where prehospital transit times are long, and to identify specific life support interventions that contributed to survival. Methods In the study period from 1997 to 2006, 2,788 patients injured by land mines, war, and traffic accidents were managed by a chain-of-survival trauma system where non-graduate paramedics were the key care providers. The study was conducted with a time-period cohort design. Results 37% of the study patients had serious injuries with Injury Severity Score ? 9. The mean prehospital transport time was 2.5 hours (95% CI 1.9 - 3.2. During the ten-year study period trauma mortality was reduced from 17% (95% CI 15 -19 to 4% (95% CI 3.5 - 5, survival especially improving in major trauma victims. In most patients with airway problems, in chest injured, and in patients with external hemorrhage, simple life support measures were sufficient to improve physiological severity indicators. Conclusion In case of long prehospital transit times simple life support measures by paramedics and lay first responders reduce trauma mortality in major injuries. Delegating life-saving skills to paramedics and lay people is a key factor for efficient prehospital trauma systems in low-resource communities.

Se presenta con más frecuencia en mujeres que en hombres y predomina en la segunda y tercera década de la vida. Las características rad [...] iográficas del GCCG son variables y pueden ser confundidas con otras lesiones de los maxilares. El GCCG puede tener un comportamiento agresivo lo que permite establecer el tratamiento de elección, incluyendo la enucleación, el curetaje y la resección en bloque de la lesión. Caso clínico: se presentaron diez casos de pacientes diagnosticados con GCCG. El 80 % de los casos se localizaron en la mandíbula con las siguientes características clínicas: asimetría facial, desplazamiento dental, reabsorción radicular, alteración de la oclusión y trastorno nervioso. Conclusiones: en cuatro sujetos se realizó resección en bloque con placa de reconstrucción, mientras que en los otros seis pacientes se llevó a cabo enucleación y curetaje. En el 100 % de los casos se efectuó un abordaje intraoral y no se presentaron complicaciones graves. El seguimiento clínico y radiográfico evidenció recidiva en uno de los pacientes, razón por la cual se precedió a realizar resección en bloque con placa de reconstrucción. Abstract in english Background: central giant cell granuloma (CGCG) is a lesion that occupies 7 % of benign tumors found exclusively in the jaws. It occurs more frequently in women than in men and predominates in the second and third decades of life. Radiographic features of CGCG are changeable, and may be confused wit [...] h other jaws' lesions. The CGCG may have aggressive behavior which allows setting the treatment of choice, including enucleation, curettage and resection of the lesion. Clinical case: ten cases of patients diagnosed with CGCG were presented. The 80 % of the cases were located in the jaw with the following clinical features: facial asymmetry, dental displacement, root resorption, altered occlusion and nerve disorder. Conclusions: in four patients resection in block was performed with reconstruction plate, while in six other patients enucleation and curettage was carried out. In the 100 % of the cases an intraoral approach was made without severe complications. There was clinical and radiographic evidence of recidivation in one of the patients, a resection with reconstruction plate was made.

Methods: Included in this retrospective/descriptive study were 30 children treated for liver tumors from 1375-1384 (ca. 1996-2005, at Children’s Hospital Medical Center, Tehran, Iran. We included the clinical, radiologic, and pathologic data of our patients, focusing on the frequency, etiology and outcome. Results: Patient ages ranged from three months to 12 years (median 3.8 years, with 18 males (60% and 12 females (40%. Of these, 17 patients had hepatoblastoma (55.66%, including 13 males and four females, with an age range of six months to five years. Four cases (13.33% had neuroblastoma. Hepatocellular carcinoma (HCC was found in three cases (10%, all of whom were carriers of hepatitis B. Two cases (6.66% were diagnosed with mesenchymal hamartoma, two cases (6.66% with hemangioendothelioma and two cases (6.66% with rhabdomyosarcoma and leiomyosarcoma of the biliary tract. Abdominal swelling and hepatomegaly were seen in all of patients. Jaundice was observed in two cases. Serum alpha-fetoprotein levels greater than 500 ng/ml were seen in 17 cases (56.66%. All patients were receiving specific treatment. The three-year survival rate was 65% for hepatoblastoma and 2% for HCC Conclusion: With the introduction of specific treatment, the survival rate for children with tumors of the liver has significantly increased. Further improvement can be achieved using diagnostic biopsy for hepatoblastoma, although it may result in complications, and preoperative chemotherapy followed by complete surgical excision (per International Society of Pediatric Oncology guidelines, yielding an outstanding survival rate of 80%.

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

Science.gov (United States)

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

Ten-year experiences with Tetanus at a Tertiary hospital in Northwestern Tanzania: A retrospective review of 102 cases  

Directory of Open Access Journals (Sweden)

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

Is Electroconvulsive Therapy Fading into Oblivion? - A Study of Ten Year Trends  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Despite proven efficacy, modified ECT has been variably used in the recent past, with data on the usage trend being scarce, worldwide. Aim: We aimed to do a time – series analysis to examine annual trends in modified ECT use in our tertiary teaching hospital in the last decade. Methods: A chart review was carried out on all patients who received m-ECT in our teaching hospital in the last ten years (2002 to 2011, and percentage of total inpatients receiving M-ECT each year was deduced. Along with number of ECT sessions given per year, details of demographic data, and indications for ECT were recorded. Results: In our study ECT was undersized as a treatment option, with only 1:13% of total inpatients having received ECT. Also it was noted that use began increasing from 2002, reaching a peak in 2006 (84% increase followed by a downward trend, with a sharp decline since 2008 (61%decrease and finally reaching a nadir in 2011 (69% decrease. Mean age of patients ranged from 31.28 to 40.1 years with a slightly high female preponderance in most year groups. The most common indication for ECT use was schizophrenia (47.8% followed by, depression (38.9%. Conclusion: Although, our study finding is in line with the downward trend of ECT utilization rates reported worldwide, the nature and magnitude of decline cannot be explained nor compared globally due to variations, inaccuracies and heterogeneity of ECT data currently available. Further, factors responsible for such trends should become focus of future research.

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

This clinico-statistical study includes 232 cases of oral squamous cell carcinoma that underwent radical treatment in the Department of Oral and Maxillofacial Surgery, Yokohama City University Hospital, during the decade from 1991 to 2000. Surgery was principally adopted as the first line for treatment in 199 cases, and radiotherapy in 33 cases. The 5-year overall survival rate was 73.4%. The results according to stage were as follows: stage I, 87.5%; Stage II, 77.9%; Stage III, 63.5%; and Stage IV A, 44.7%. The primary sites were classified as follows: upper gingiva, 85.2%; tongue, 73.7%; floor of mouth, 68.9%; lower gingiva, 66.3%; buccal mucosa, 63.9%; and hard palate, 50%. For tongue cancer, the 5-year overall survival rates by stage were: Stage I, 90.8%; Stage II, 82.1%; Stage III, 40.3%; and Stage IV A, 45.7%. Statistical significance was seen between cases of Stages I and II and those of Stages III and IV A stage. For lower gingival cancer, the 5-year overall survival rates by stage were: Stage I, 90.8%; Stage II, 82.1%; Stage III, 40.3%; and Stage IV A, 45.7%. Even in Stage I lower gingival cancers had unfavorable clinical outcomes. Preventive neck dissections were performed on 52 N 0 neck patients, but clinically negative nodes however showed metastasis in 14 patients (26.9%). (author)

Campylobacter antimicrobial resistance in Peru: a ten-year observational study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Campylobacter jejuni and Campylobacter coli are food-borne pathogens of great importance and feature prominently in the etiology of developing world enteritis and travellers’ diarrhoea. Increasing antimicrobial resistant Campylobacter prevalence has been described globally, yet data from Peru is limited. Our objective was to describe the prevalence trends of fluoroquinolone and macrolide-resistant C. jejuni and C. coli stool isolates from three regions in Peru over a ten-year period. Methods Surveillance for enteric pathogens was conducted in Lima, Iquitos and Cusco between 2001 and 2010. Campylobacter stool isolates were tested for susceptibilities to ciprofloxacin, azithromycin and erythromycin. Susceptibilities were reviewed for 4652 isolates from Lima ( n?=?3419, Iquitos ( n?=?625 and Cusco ( n?=?608. Results Comparing the study periods of 2001-2005 and 2006-2010, prevalence of ciprofloxacin-resistant C. jejuni isolates rose in the study areas of Lima (73.1% to 89.8%, p?p?C. coli rates also increased in Lima (48.1% to 87.4%, p?p?=?0.005. Small but significant increases in azithromycin-resistant and erythromycin-resistant C. jejuni prevalence were noted in Iquitos (2.2% to 14.9%, p?p?=?0.002, and erythromycin-resistant C. coli rates increased in Lima (0.0% to 5.3%, p?=?0.038. The prevalence of C. jejuni isolates resistant to both ciprofloxacin and azithromycin increased in Iquitos (0.3% to 14.9%, p?C. jejuni isolates resistant to both ciprofloxacin and erythromycin rose in Iquitos (0.0% to 14.9%, p?C. coli prevalence increased in Lima (0.0% to 5.3%, p?=?0.034. Conclusions These results have implications for the empirical management of enterocolitis in Peru. Ongoing surveillance is essential to guide appropriate antimicrobial use in this setting. Local epidemiological studies to explore the relationship between increasing antimicrobial resistance and agricultural or human antibiotic use may be valuable.

The Result of The Treatment of Infantile Spasm After Two Year Follow-Up Review Of 45 Cases in Ten Past Years  

Directory of Open Access Journals (Sweden)

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.

Consequences from use of reminiscence - a randomised intervention study in ten Danish nursing homes  

Directory of Open Access Journals (Sweden)

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 contact with residents' and SF-12 self-rated mental health. At 12 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Emotional exhaustion and 'Professional role and development'. Conclusions The use of reminiscence appeared to have little long-term effect on the nursing home residents. Nursing staff in the Intervention Group experienced greater satisfaction with professional roles and developed a more positive view of the residents.

Mercury Studies around the Mediterranean Sea Basin: Ten years of Measurements and Modeling results  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Only a few years ago the presence of Reactive Gaseous Mercury (RGM) was believed to be almost exclusively the result of anthropogenic emissions and that sustained high RGM concentrations in the MBL were not considered likely. During the past ten years, an in-depth investigation was carried out in the Marine Boundary Layer (MBL) of the Mediterranean Sea to quantify and possibly explain spatial and temporal patterns of Hg-species concentrations. This paper provides an overview of modeling resul...

Ten-year study on varieties of parotid tumors in pediatrics  

International Nuclear Information System (INIS)

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

New polyethylenes in total hip replacement: A ten- to 12-year follow-up study.  

Science.gov (United States)

Between 1999 and 2001, 90 patients underwent total hip replacement using the same uncemented acetabular and femoral components with a 28 mm metallic femoral head but with prospective randomisation of the acetabular liner to either Durasul highly cross-linked polyethylene or nitrogen-sterilised Sulene polyethylene. We assessed 83 patients at a minimum follow-up of ten years. Linear penetration of the femoral head was estimated at six weeks, six and 12 months and annually thereafter, using the Dorr method, given the non-spherical shape of the acetabular component. There was no loosening of any component; only one hip in the Sulene group showed proximal femoral osteolysis. The mean penetration of the femoral head at six weeks was 0.08 mm (0.02 to 0.15) for the Durasul group and 0.16 mm (0.05 to 0.28) for the Sulene group (p = 0.001). The mean yearly linear penetration was 64.8% lower for the Durasul group at 0.05 mm/year (sd 0.035) for the Sulene group and 0.02 mm/year (sd 0.016) for the Durasul (p < 0.001). Mean linear femoral head penetration at ten years was 61% less in the Durasul than Sulene group. Highly cross-linked polyethylene gives excellent results at ten years. PMID:23450015

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

Directory of Open Access Journals (Sweden)

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 tested.

Study of uranium matrix interference on ten analytes using inductively coupled plasma atomic emission spectrometry  

Energy Technology Data Exchange (ETDEWEB)

Maximum allowable concentrations of 12 elements in uranium hexafluoride feed for enrichment to reactor grade material (about 3%), vary from 1 to 100 ppm ([mu]g/g). Using an inductively coupled plasma atomic emission spectrometer, 51 lines of tine of these elements (B, Cr, Mo, P, Sb, Si, Ta, Ti, V and W) has been studied with a uranium matrix to investigate the matrix interference on the basis of signal to background (SBR), and background to background ratios (BBR). Detection limits and limits of quantitative determination (LQDs) were calculated for these elements in a uranium matrix using SBR and relative standard deviation of the background signal (RSD[sub B]) approach. In almost all cases, the uranium matrix interference reduces the SBRs to the extent that direct trace analysis is impossible. A uranium sample having known concentrations of impurities (around LQDs) was directly analysed with results that showed reasonable accuracy and precision. (Author).

Henoch-Schönlein purpura outcome in children: A ten-year clinical study  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Henoch-Schönlein purpura (HSP is the most common vasculitis of childhood. It is characterized by symptoms including nonthrombocytopenic purpura, abdominal pain, haematuria/proteinuria, and arthralgia/arthritis. The pleiomorphism of clinical signs in HSP could be confused with other conditions or other vasculitis forms. Objective. Evaluation of HSP clinical presentation, the onset and severity of renal manifestation in affected children and their outcome. Methods. A retrospective study of 49 patients diagnosed with HSP was conducted from September 1999 to September 2009. Children with severe renal manifestations (nephrotic range proteinuria, with or without nephrotic or nephritic syndrome have undergone kidney biopsy. Results. Twenty-five patients developed renal manifestations after onset of the disease. In our study child’s older age was a risk factor for association with HSP nephritis. Six of the patients required kidney biopsy. They were successfully treated with various immunosuppressive protocols, as well as three of nine patients with nephrotic range proteinuria. Two patients developed most severe form of HSP nephritis, nephrotic-nephritic syndrome with histology grade IIIb/IVb. During the study period (average follow-up 6 years, all patients had a normal global renal function with mild proteinuria in only two cases. The prognosis of renal involvement was better than reports from other patient series. Conclusion. Long-term morbidity of HSP is predominantly attributed to renal involvement. During the study period, no patient had renal insufficiency or end stage renal disease after various combinations of immunosuppressive treatment. It is recommended that patients with HSP nephritis are followed for longer periods of time with a regular measurement of renal function and proteinuria.

Ten-year experiences with Tracheostomy at a University teaching hospital in Northwestern Tanzania: A retrospective review of 214 cases  

Directory of Open Access Journals (Sweden)

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 and trained staff.

Regulatory reform - case studies  

International Nuclear Information System (INIS)

This report focuses on issues associated with the President's regulatory reform program. The objectives of reform are related to the reduction of overall schedules and to the lowering of costs by reducing construction and engineering manpower, equipment costs and commodities. Consistent with these objectives is the goal to provide a more practical approach to engineering design and construction consistent with realistic safety goals. In order to assist DOE in its responsibility to recommend improvements to the nuclear regulatory process, specific examples of regulatory requirements and their industrial interpretation were sought on a case study basis. The case studies program is aimed at exploring the commodity and labor productivity aspects of piping, electrical systems, and concrete. Five nuclear power plant projects and a fossil project were visited for the case studies to determine design and construction procedures and relative productivity. The paper summarizes the findings

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

International Nuclear Information System (INIS)

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)

Ten-year study of strategies for teaching clinical inference in predoctoral orthodontic education.  

Science.gov (United States)

Dealing with the continuum of malocclusions in general practice requires diagnostic skills that, according to the Council on Dental Education guidelines, should include an ability to evaluate the severity of malocclusions and to assess the degree of treatment difficulty. This level of diagnostic skills is predicated upon the ability to make a judgment on the basis of inherently ill-defined and insufficient data or, in other words, upon the ability to use rules and procedures of clinical inference. However, conventional methods of predoctoral orthodontic instruction appear to be unsuitable for transmitting these complex skills to dental students. For ten years, alternative instructional strategies involving guided discovery learning, repetitive practice in application of facts and principles to real-life problems, and eventually a prescriptive diagnostic model were employed at our institution. Both classroom instruction and evaluation were focused on attaining mastery in two narrowly specified domains: "Evaluating the Severity of Malocclusions" and "Assessing the Degree of Treatment Difficulty." The large proportion of items mastered by students and the high percent correct recorded on multiple-choice examinations suggest that these instructional methods may be effective for teaching clinical inference at the predoctoral level of dental education.

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: Afrikaner Abstract in english During the past few years, Archaetnos has been involved in various land claims, with a view to collecting historical, anthropological and archaeological information in order to determine the validity of such claims. This was done by doing deeds searches and studying archival material and anthropolog [...] ical literature, followed by a field survey where claimants indicated sites linked to their history and where they were interviewed. In some cases it was clear from the onset that misperceptions about South African history pertain. Even when information is correct, there is sometimes chronological chaos and in certain instances so-called "facts" are being fabricated. The above-mentioned information is used by the Land Claims Commission (LCC) to determine the merit of a claim. The lack of knowledge at this institution frequently results in cases being approved for the process even when such approval was clearly based on incorrect information. The land claim of the BaPhalane Ba Ramokoka community is one such example. In the article the reasons for land claims in general are listed. The merit of the BaPhalane claim, as well as the information obtained during the research process, is then discussed against this background. This is, however, not done in detail, as the article insteadfocuses on the general problem created by historical misperceptions. The findings of the research were that although the BaPhalane had a valid claim to at least four of the thirty-two farms listed, they had no valid claim to at least eighteen others. This was confirmed by the court judgement. It is concluded that the lack of knowledge at the Land Claims Commission results in many cases being unnecessarily investigated. This results in high costs, a waste of time and an unproductive system. It is therefore clear that information is required at a much earlier stage during the land claims process.

Congenital anomalies among live births in a polluted area. A ten-year retrospective study  

Directory of Open Access Journals (Sweden)

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.

The top ten list: lessons learned from teaching a study abroad course.  

Science.gov (United States)

In response to the need for culturally competent care, faculty can instill in students the desire to become culturally competent practitioners by providing the opportunity to participate in a short-term study abroad immersion experience. While this strategy is not considered cutting-edge or revolutionary, changing global dynamics warrant rethinking this curricular option. Nurse faculty conducted two short-term study abroad courses in Croatia. Students explored health care and nursing education in this Eastern European country and participated in a service-learning project. Based on their experiences, the authors offer five dos and five don'ts for planning and implementing a successful study abroad course. PMID:22029242

A Review of Ten Years of the Study for Monitoring Antimicrobial Resistance Trends (SMART from 2002 to 2011  

Directory of Open Access Journals (Sweden)

Full Text Available Surveillance of antimicrobial agent resistance provides important information to guide microbiologists and infectious disease specialists understanding of the control and the spread of resistance mechanisms within the local environment. Continued monitoring of antimicrobial resistance patterns in the community and in local hospital environments is essential to guide effective empiric therapy. The Study for Monitoring Antimicrobial Resistance Trends (SMART has monitored the in vitro susceptibility patterns of clinical Gram-negative bacilli to antimicrobial agents collected worldwide from intra-abdominal infections since 2002 and urinary tract infections since 2009. Resistance trends, with a particular focus on carbapenem resistance and the rate of extended-spectrum ?-lactamases (ESBLs, were analyzed. Isolates from intra-abdominal infections (n = 92,086 and urinary-tract infections (n = 24,705 were collected and tested using Clinical and Laboratory Standards Institute methods. This review presents carbapenem susceptibility and ESBL rates over ten years of SMART study analysis, including key publications during this period. The SMART study has proved to be a valuable resource in determining pathogen prevalence and antibiotic susceptibility over the last ten years and continues to provide evidence for regulatory susceptibility breakpoints and clinical decision making.

Case study of isosurface extraction algorithm performance  

Energy Technology Data Exchange (ETDEWEB)

Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

Bacteriological profile of community acquired acute bacterial meningitis: A ten-year retrospective study in a tertiary neurocare centre in South India  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: Ten years retrospective study to evaluate the bacteriological spectrum of community acquired acute bacterial meningitis (CAABM. Methods: Cerebrospinal fluid (CSF samples from 385 clinically suspected cases of pyogenic meningitis were processed for cell counts, cytospin Gram stain, culture, antigen detection by latex agglutination (LAT and antibiotic susceptibility test. Eighteen of these CSF samples were also subjected to a polymerase chain reaction (PCR assay for detection of pneumococcal DNA. Results: The etiological agent could be identified in 284 (73.8% of the total 385 cases by culture and/or smear and /or LAT. Streptococcus pneumoniae was the predominant pathogen accounting for 238 (61.8% cases. Haemophilus influenzae and Neisseria meningitidis accounted for 7 (1.8% and 4 (1% cases respectively. Other gram negative bacilli, Streptococcus spp. and Staphylococcus aureus were isolated from 19 (4.9%, 9 (2.3% and 7 (1.8% cases respectively. Conclusions: Streptococcus pneumoniae remains the major aetiological agent of CAABM both in adults and children in our set-up. No penicillin resistance was detected among the isolates. Further research should focus on preventable aspects of CAABM, especially pneumococcal vaccines, to help reduce the disease burden.

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 (n = 1402 to 1902).

INTRAVENOUS PULSE CYCLOPHOSPHAMIDE TREATMENT OF LUPUS NEPHRITIS: A RETROSPECTIVE TEN YEARS STUDY  

Directory of Open Access Journals (Sweden)

Full Text Available Nephritis remains an important problem in patients with systemic lupus erythematosus (SLE. We conducted retrospective study to evaluate the efficiency of intravenous pulse cyclophosphamide in lupus nephritis: From 1983 to 1993, we reviewed 133 patients with biopsy proven lupus nephritis, 47 of them excluded because of short period of follow-up or defective laboratory data. Eighty six patients were treated with the following regimens: Sixty patients with intravenous pulse cyclophospham; 13 witli IV pulse methylprednisolone succinate, 8 with cyclosporine, 4 with azathioprine and one with oral prednisolone. Sixteen patients did not respond to IV cyclophosphamide. We evaluated renal biopsy, pretreatment mean arterial pressure (MAP, BUN, creatinine and proteinuria as-prognostic and risk factors of nonresponders. The results of this study showed that diffuse proliferative glomerulonephritis (DPGN had the poorest outcome and most of nonresponders (11/16, were of DPGN. Tliere was a correlation between initial serum creatinine level and response to IV cyclophosphamide, but there was no correlation between BUN, MAP, degree of proteinuria and response to IV cyclophosphamide. IV pulse cyclophosphamid was more effective than steroid alone in preventing renal failure in lupus nephritis.

Ten year longitudinal study of neuropsychological functioning subsequent to a first episode of schizophrenia.  

Science.gov (United States)

We previously reported relative stability in neuropsychological functions over a 4- to 5-year period after the onset of a first episode of schizophrenia, with patients demonstrating less improvement than controls on some functions [Hoff, A.L., Sakuma, M., Wieneke, M., Horon, R., Kushner, M., DeLisi, L.E., 1999. A longitudinal follow-up study of neuropsychological functioning subsequent to a first-episode of schizophrenia. American Journal of Psychiatry 156, 1336-1341.]. The current study was conducted to extend follow-up evaluations through 10 years of illness to determine whether neuropsychological functions remain stable or deteriorate over a longer time period. Twenty-one first episode patients and 8 controls were re-evaluated 10 years after an initial evaluation on neuropsychological and clinical measures. Repeated measures analyses demonstrated no differences between patients and controls in degree of change over this time period nor was change in symptoms reliably associated with improvement or deterioration in cognitive abilities. However, baseline level of cognitive functioning was correlated with the degree of change. Thus, when the baseline level of functioning was controlled for in the analyses, less or lack of improvement was seen in the patients compared with controls in verbal intellectual functioning, delayed verbal and nonverbal recall, and cognitive inhibition (Stroop Color Word Test). In no test did patients deteriorate significantly more than controls. We conclude that most first episode patients have had considerable cognitive decline by the time of their first hospitalization and that it remains relatively stable through at least 10 years of illness. Most cognitive change takes place early in this illness, prior to the first hospitalization, but its exact timing still remains unknown. PMID:15964177

The purpose of the register is to gain information about severe allergic reactions to food in Norway and to survey food products in relation to allergen labelling and contamination. Cases are reported on a voluntary basis by first line doctors, and submitted together with a serum sample for specific IgE analysis. The register has received a total of 877 reports from 1 July, 2000 to 31 December, 2010. Two age groups, small children and young adults are over-represented, and the overall gender distribution is 40:60 males-females. The legumes lupine and fenugreek have been identified as two “new” allergens in processed foods and cases of contamination and faults in production of processed foods have been revealed. The highest frequency of food specific IgE is to hazelnuts and peanuts, with a marked increase in reactions to hazelnuts during the last three years. The Food Allergy Register has improved our knowledge about causes and severity of food allergic reactions in Norway. The results show the usefulness of population based national food allergy registers in providing information for health authorities and to secure safe food for individuals with food allergies.

Goiania incident case study  

Energy Technology Data Exchange (ETDEWEB)

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.

Oxford phase 3 unicompartmental knee arthroplasty in Japan--clinical results in greater than one thousand cases over ten years.  

Science.gov (United States)

There are few reports of the Oxford unicompartmental knee arthroplasty (UKA) survival rate in Asia. This study describes outcomes of 1279 Oxford UKAs for Japanese patients. The mean follow-up was 5.2 years. We divided patients into two groups based on preoperative indications (extended indications group and strict indications group). The Oxford knee score improved from 22.3 to 40.8 (P=0.041). The 10-year survival rate using revision was 95%. A total of 25 UKAs (2.0%) required revision. The most common reason was subsidence of tibial component. The 5-year cumulative survival rate of the strict indications group was significantly higher than that of the extended indications group (99.1% vs. 93.8%, P<0.001). When we followed inclusion criteria strictly, good clinical results were achieved in Asia. PMID:24099572

Energy Technology Data Exchange (ETDEWEB)

An overview of Fortis Ontario, formerly the Canadian Niagara Power Company Ltd. was presented along with details of its distribution businesses, assets and Newfoundland-based parent company, including operating companies and utility operating companies. Recent distribution investments and acquisitions were reviewed. An outline of facts concerning Ontario's distribution sector was presented with details of fragmentation, local distribution company (LDC) consultation procedures and transfer taxes. A case study of Port Colborne Hydro was provided, with an outline of operational synergy implementations including improved flexibility of existing staff; harmonization of labour contracts; a reduction in equipment and fleet costs; and centralization of stores and local customer service centres. An account of back-office efficiencies introduced at Port Colborne was presented, including an information technology (IT) system; accounting and billing modifications; new regulatory and tax efficiency measures; and a guaranteed cash flow for the municipality. Details concerning the purchase of Cornwall Electric were presented along with details of several operational synergies implemented after the purchase such as work sharing between regional operations; consolidation of equipment and fleet cost; a reduction of some positions; a local customer service centre; and separate labour unions and contracts. New corporate synergies included: an IT system; accounting and billing; regulatory and human resources modifications; and safety and environmental modifications. Cost savings results for 2003 were presented, with $870, 000 in captured savings and $1,343, 000 in sustained annual savings. A chart of reduced operating costs per customer was also provided. It was concluded that in order to integrate acquisitions, it was essential to establish a task force prior to closing and implement a new organization structure as quickly as possible. A regional approach to operation and service delivery was recommended, as well as an emphasis on reducing cost and not service levels. Success required a common culture and standards, with rigorous attention to details, discipline and controllable costs, as well as full accountability. tabs., figs.

Measurement of implementation components ten years after a nationwide introduction of empirically supported programs – a pilot study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Ten years after the nationwide dissemination of two evidence-based treatment programs, the status of the implementation components was evaluated in a cross-sectional study. The aim of the study was to pilot a standardized measure of implementation components by examining the factor structure, the reliabilities of the scores, and their association with implementation outcome variables. The aim was also to compare implementation profiles of the two evidence-based programs based on multi informant assessments. Methods The 218 participants in the study were therapists, supervisors, and agency leaders working with Parent Management Training, the Oregon model (PMTO, and Multisystemic Therapy (MST in Norway. Interviewers filled in an electronic version of the Implementation Components Questionnaire during a telephone interview. Results The factor analysis of the eight one-dimensional subscales resulted in an individual clinical-level factor and an organizational system-level factor. Age, experience, and number of colleagues in the workplace were negatively correlated with positive ratings of the implementation process, but the number of colleagues working with the same program predicted positive ratings. MST and PMTO had different implementation profiles and therapists, supervisors, and managers evaluated some of the implementation drivers significantly differently. Conclusions The psychometric quality of the questionnaire was supported by measures of internal consistency, factor analyses of the implementation components, and the comparisons of implementation profiles between programs and respondent groups. A moderate, but consistent association in the expected direction was found with the implementation outcome variables.

Leukemia in women following radiotherapy for cervical cancer: ten-year follow-up of an international study  

International Nuclear Information System (INIS)

An international collaborative study, with 69 references, of 31,219 women treated for cervical cancer from 30 radiotherapy centers in nine countries was conducted. Patients were followed clinically and with blood studies between 1960 and 1970, and 148,000 woman-years (WY) were accumulated. Among 28,490 women treated with either intercavitary radium, external radiation, or both, 134,000 WY were accumulated and 13 cases of leukemia were observed. On the basis of general population rates, 15.5 cases were expected. A twofold risk could thus be excluded, but a 1.4-fold risk remained possible. In absolute terms, risks larger than 0.1 leukemia cases per 106 WY-rad could be excluded. Among 2,729 cervical cancer patients not irradiated but similarly evaluated, 14,000 WY were accumulated and 2 cases of leukemia were observed as compared with 1.0 expected. In the interval 4-8 years after exposure, the period in which any leukemogenic effect might be most apparent, 7 cases of leukemia were observed among exposed patients as compared with 5.4 expected. The absence of an increased leukemia risk suggested that the radiation regimens used to treat cervical cancer are not so effective in inducing leukemia as are other radiation exposures that have been studied

Studies on some rare earth metal complexes: ten- and six-coordinated complexes of an unsymmetrical aminoacid derivative  

International Nuclear Information System (INIS)

2,4-dihydroxybenzaldehyde (N-benzoyl)glycyl hydrazone, H3 dhbbgh, has been synthesized and characterized. Rare earth metal complexes of the empirical formulae, [Ln(H3 dhbbgh)2Cl2]Cl.nH2O and [Ln(dhbbgh)(H2O)2], where Ln = La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III), Dy(III) and Y(III) have been synthesized and characterized by elemental analyses, molar conductances, magnetic susceptibilities, electronic, infrared and NMR spectral studies. Various bonding parameters (?,b1/2,% ? and ?) calculated from the electronic spectra of Pr(III), Nd(III), Sm(III) and Dy(III) complexes suggest a weak covalent bond between the metal and ligand. The theoretical oscillator strengths (Pcalcd) and a set of three intensity parameters (T?=2,4,6) computed from the Judd-Ofelt equation are found to be in good agreement with experimental values. On the basis of the spectral profiles of the hypersensitive transitions (4I9/2 --> 4G5/2, 2G7/2) in the Nd(III) complexes, coordination numbers ten and six have been proposed for the Ln(III) ions in the adduct and deprotonated complexes respectively.

Reproductive factors and breast cancer risk among BRCA1 or BRCA2 mutation carriers: results from ten studies.  

Science.gov (United States)

Although reproductive factors are among the most well-established risk factors for breast cancer in the general population, it is still a matter for debate whether these factors act as risk modifiers among BRCA1 or BRCA2 mutation carriers. This meta-analysis is the first to be performed to determine the relationship between reproductive factors and breast cancer risk among BRCA1 and BRCA2 mutation carriers. We searched the PubMed database up to February 2013. A total of ten studies met the inclusion criteria. The results showed that the reproductive factors may be associated with breast cancer risk only among BRCA1 mutation carriers. No association was found between parity and breast cancer risk. Compared with women at the youngest age in the first-birth category, women in the oldest age category were at a 38% lower risk of breast cancer (RR=0.62, 95%CI=0.45-0.85). Breastfeeding for at least 1 or 2 years was associated with a 37% reduction in breast cancer risk (RR=0.63, 95%CI=0.46-0.86). Women at the oldest age in the menarche category were at a 34% lower risk of breast cancer (RR=0.66, 95%CI=0.53-0.81) than women in the youngest age category. However, none of the reproductive factors were associated with breast cancer risk among BRCA2 mutation carriers. In conclusion, late age at first birth, breastfeeding, and late age at menarche protect against breast cancer in BRCA1 mutation carriers only. Further studies are needed to explore the mechanisms.

Cervical neoplasia case studies  

Directory of Open Access Journals (Sweden)

Full Text Available Cancer is nowadays one of the most important health problems. In Romania cancer is the second in generalmorbidity after cardio-vascular diseases, being followed by respiratory diseases, accidents and trauma. Considering thefact that cancer has an insidious start, a slow irreversible development towards physical and psychic invalidity, and that it affects both the person and the family and society, we can say it is very important to have a study of this illness from thesocial and medical point of view. The cytological examination offers, apart from the highlighting of the tumour cells, thepossibility of assessing the hormonal status, and also of identifying vaginal flora. Cervical cancer is a serious chroniccondition, which has great medical and social importance and has a severe evolution when detected in advanced stages.

Case Studies in Science Ethics  

Science.gov (United States)

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

The Case Study: Professional Development Cases  

Science.gov (United States)

A professional development case in college science teaching bridges the gap between educational theory and practice. A good case poses an interesting dilemma involving instructors, students, and administrators. Case discussions can help instructors take charge of their own professional development and create a community of shared professional support within their colleges. These discussions help overcome the sense of isolation that many instructors, particularly new ones, can experience.

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

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusion 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 causes of cancer in children. Due to the little that is known about the incidence of cancer in Mexican children, it will be necessary to develop a national program to establish a cancer registry for the whole of the country.

Prophylactic titanium elastic nailing (TEN) following femoral lengthening (Lengthening then rodding) with one or two nails reduces the risk for secondary interventions after regenerate fractures: a cohort study in monolateral vs. bilateral lengthening procedures  

Science.gov (United States)

Background Femoral fracture rates of up to 30% have been reported following lengthening procedures using fixators. “Lengthening then rodding” uses one or two titanium elastic nails (TENs) for prophylactic intramedullary nailing to reduce this complication. The aim of the study was to decide if usage of only one TEN is safe or has it a higher risk of getting a fracture? And we asked if there is a difference between patients with monolateral or bilateral lengthening procedures according to their fracture rate? Methods One or two TENs were implanted in two groups of patients (monolateral and bilateral) after femoral lengthening procedures. The regenerate quality was classified using the Li system and fractures were categorized using the Simpson and Kenwright classification. The follow-up period was at least 1 year after removal of the frame. Results Sixty-seven patients with 101 femoral lengthening procedures were included in 2007–2011. Group A included 34 patients with bilateral lengthening due to congenital short stature. Group B consisted of 33 patients with congenital disorders with leg length discrepancies. Seven fractures in six patients were seen in group A and five fractures in group B. One patient had residual shortening of 1 cm, and 11 fractures healed without relevant deviation (< 5°) or shortening (< 5 mm). A soft-tissue infection in one patient led to early removal of one TEN. Conclusions Fractures occurred in both groups of patients in total in 12 of the 101 cases (12%). The rate of secondary interventions was markedly reduced. Usage of one or two TENs did not influence the fracture rate.

Os Trigonum Syndrome: A Case Study  

Directory of Open Access Journals (Sweden)

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.

Ten Problems in Experimental Mathematics  

Energy Technology Data Exchange (ETDEWEB)

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.

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

International Nuclear Information System (INIS)

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

Short Term Effects of Nitrogen Dioxide on Mortality and Susceptibility Factors in Ten Italian Cities: the EpiAir Study.  

Science.gov (United States)

Background. Several studies have shown an association between nitrogen dioxide (NO2) and mortality. In Italy the EpiAir multicentric Study "Air Pollution and Health: Epidemiological Surveillance and Primary Prevention" investigated short-term health effects of air pollution, including NO2. Objectives. To study the individual susceptibility, we evaluated the association between NO2 and cause-specific mortality, investigating individual socio-demographic features and chronic/acute medical conditions as potential effect modifiers. Methods. We considered 276,205 natural deaths of persons over 35 years of age, resident in 10 Italian cities and deceased between 2001 and 2005. We chose a time-stratified case-crossover analysis to evaluate the short term effects of NO2 on natural, cardiac, cerebrovascular and respiratory mortality. For each subject we collected information on socio-demographic features and hospital admissions in the previous two years. Fixed monitors provided daily NO2, PM10 and ozone concentrations. Results. We found statistically significant associations with 10 ?g/m3 increases of NO2, i.e. for natural mortality (2.09% for lag 0-5, 95 CI% 0.96:3.24), for cardiac mortality (2.63% for lag 0-5, 95 CI% 1.53:3.75) and respiratory mortality (3.48% for lag 1-5, 95 CI% 0.75:6.29). These associations were independent from those of PM10 and ozone. Stronger associations were estimated for subjects with at least one hospital admission in the two previous years and for subjects with three or more specific chronic conditions. Some cardiovascular conditions (i.e. ischemic heart diseases, pulmonary circulation impairment, heart conduction disorders, heart failure) and diabetes appeared to confer a strong susceptibility to air pollution. Conclusions. Our results suggest significant and likely independent effects of NO2 on natural, cardiac and respiratory mortality particularly among subjects with specific cardiovascular pre-existing chronic conditions and diabetes.

BioFleet case studies  

International Nuclear Information System (INIS)

These six case studies examined the use of different biodiesel blends as fuel supply sources for businesses in British Columbia (BC). In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not encountered any operational differences in their field operations since switching to biodiesel. 26 figs

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

Directory of Open Access Journals (Sweden)

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 accelerates its apparition by about 5.5 years.

Case study in Reunion Island  

Science.gov (United States)

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

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

Science.gov (United States)

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 costs in bankside analysis through technology development, and the scientific advantages of these data are clear and exciting. When integrating its use with policy appraisal, it must be made clear that the advances in river process understanding from high resolution monitoring data capture come as a package with the ability to make more informed decisions through an investment in better information.

A case study of Impetigo  

Directory of Open Access Journals (Sweden)

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

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 perspectiveâ??the picnic is revealed to be taking place near Soldier Field on Chicago's waterfrontâ??and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe.

A parathyroid scintigraphy case study  

Energy Technology Data Exchange (ETDEWEB)

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.

Recovery Potential of a Western Lowland Gorilla Population following a Major Ebola Outbreak: Results from a Ten Year Study  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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 ...

Course of retinopathy in children and adolescents with insulin-dependent diabetes mellitus: a ten-year study.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The prevalence and development of retinal changes were longitudinally documented from 1978 to 1987 in 112 insulin-dependent diabetic children by means of fluorescein angiography and fundus photography. At the end of the study period, 43 patients (38.4%) developed retinal changes, most of which were classified as minimal. Age, diabetes duration, puberty and long-term metabolic control were found to be independent factors affecting the development of retinopathy.

Chernobyl - ten years after  

International Nuclear Information System (INIS)

This folder contains ten brief factsheets which aim to give a balanced presentation of the facts relating to the reactor accident at the Chernobyl power station ten years after the event. Details of the incident are given and its aftermath, in particular as it has affected the lives and health of people living in the immediate vicinity, is considered. Since records of the health of people in the region before the accident were very poor, it is extremely difficult to make definitive statements about the health effects of the accident. It is clear, however, that there has been a marked increase in the incidence of thyroid cancer especially among children in Belarus. Although curable this has given rise to deaths owing to poor health care. It is likely that deaths due to other cancers will occur in the longer term. Though estimates vary, they are in the region of 10-25,000 world wide over the next 70 years. Comparisons with the numbers of deaths from other large-scale non-nuclear industrial disasters are provided which put the Chernobyl incident in context and experts who refute the wilder claims made in the media are quoted. The status of the plant today and the international effort to improve the safety of the 15 original RMBK commercial reactors still operating in the former USSR are described. (Author)

Case Studies in Strategic Bombardment  

Canada Institute for Scientific and Technical Information (Canada)

This volume, the third in a series of historical case studies of important air power missions, addresses the most controversial air power mission of all: strategic bombardment. The ability of aircraft and missiles to destroy or disrupt an enemy's war-making potential and to break or weaken his will to resist, independent of the actions of ground and naval forces, has served as the central theme of air power theory and as the rallying point of air advocates, who made it the raison d'etre for independent air forces. Written by well-known military historians, each chapter stands alone as a case study of an important stage in strategic air operations; combined, the chapters provide a comprehensive and insightful analysis of the theory and practice of strategic bombardment from its inception in World War I through the Gulf War of 1991. From "Boom" Trenchard and "Billy" Mitchell to John Warden and Charles Horner, the vision of air power prophets and airmen is tested against the reality of bureaucratic inertia, aircraft capability, technological advances, and bombing accuracy. This exceptional volume surveys the entire history of strategic bombardment and its technology, from the Zeppelin and Gotha of the Great War to the F-117 and the penetrating precision guided bomb of the Gulf War. The reader will find technological advances, such as radar bombing and range-extending air-to-air refueling, that answer one problem only to produce new requirements and expectations that demand more advanced technology. The volume also examines the changes in the public's perception of strategic bombardment. Indeed, public acceptance of combat casualties for both friend and foe has steadily declined in the latter half of the 20th century. Finally, later chapters in the book consider some of the most significant missions and accomplishments of the U.S. Air Force during the Cold War. The work contains over 160 photographs, 21 maps, 17 charts, and 17 tables.

Comparative pathogenicity study of ten different betanodavirus strains in experimentally infected European sea bass, Dicentrarchus labrax (L.).  

Science.gov (United States)

Viral encephalopathy and retinopathy (VER), otherwise known as viral nervous necrosis (VNN), is a severe pathological condition caused by RNA viruses belonging to the Nodaviridae family, genus Betanodavirus. The disease, described in more than 50 fish species worldwide, is considered as the most serious viral threat affecting marine farmed species in the Mediterranean region, thus representing one of the bottlenecks for further development of the aquaculture industry. To date, four different genotypes have been identified, namely red-spotted grouper nervous necrosis virus (RGNNV), striped jack nervous necrosis virus (SJNNV), tiger puffer nervous necrosis virus and barfin flounder nervous necrosis virus, with the RGNNV genotype appearing as the most widespread in the Mediterranean region, although SJNNV-type strains and reassortant viruses have also been reported. The existence of these genetically different strains could be the reason for the differences in mortality observed in the field. However, very little experimental data are available on the pathogenicity of these viruses in farmed fish. Therefore, in this study, the pathogenicity of 10 isolates has been assessed with an in vivo trial. The investigation was conducted using the European sea bass, the first target fish species for the disease in the Mediterranean basin. Naive fish were challenged by immersion and clinical signs and mortality were recorded for 68 days; furthermore, samples collected at selected time points were analysed to evaluate the development of the infection. Finally, survivors were weighed to estimate the growth reduction. The statistically supported results obtained in this study demonstrated different pathogenicity patterns, underlined the potential risk represented by different strains in the transmission of the infection to highly susceptible species and highlighted the indirect damage caused by a clinical outbreak of VER/VNN.

Quantifying Wetland Functions: A Case Study  

Science.gov (United States)

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 hypothesis was supported by the finding that the estimated bed shear during large events exceeded laboratory measurements of the critical shear stress of bed sediment samples. In the case of total phosphorus, the inflow to the wetland about equaled the outflow, although the wetland sequestered 40% of the incoming dissolved reactive phosphorus. The discrepancy is almost certainly due to net export of sediment. Wetlands such as this are very common in the glaciated portion of the U.S., and many contain channels and ditches. The region is dominantly agricultural, and sediment and phosphorus are the primary causes of impaired surface-water quality. Our results suggest that these wetlands are not very effective in mitigating this impairment when flow is concentrated in channels.

The Ten Thousand Kims  

CERN Document Server

In the Korean culture the 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 here shown 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 the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to 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 year 500 AD, based on the RGF model and find about ten thousand Kims.

The case for case studies: Optimising the use of communication cases  

Directory of Open Access Journals (Sweden)

Full Text Available Case studies are widely used by communication and public relations practitioners and educators. Yet, despite their extensive use, the question should be asked whether public relations case studies are applied in the best possible way. Many tertiary education institutions are moving away from case study analysis as a discrete subject and instead adopting a ‘case study approach’ across the communication curriculum. This paper explores the merits of different styles of the case method and the reference materials available, and concludes that formalised analysis of case studies is essential to fully optimise their application.

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  

Directory of Open Access Journals (Sweden)

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 current processes used to disseminate and implement BFHI need to be reviewed. The findings suggest that there is a contradiction between the broad philosophical stance and best practice approach of this global strategy and the tendency for health professionals to focus on the ten steps as a set of tasks or a checklist to be accomplished. The perceived procedural approach to implementation may be contributing to lower rates of breastfeeding continuation.

Spectrum of fungal keratitis:clinicopathologic study of 44 cases  

Directory of Open Access Journals (Sweden)

Full Text Available AIM:To determine the causative agents of fungal keratitis and study the predisposing factors over a period of ten years in a single tertiary care hospital.METHODS:A retrospective analysis of fungal corneal ulcers was done from 2003-2012. Patients’ clinical data were noted from the file records. Correlation of histopathological diagnosis was done with the report on fungal culture.RESULTS: Mycotic keratitis was established in 44 cases by a positive fungal culture. Direct microscopic examination of potassium hydroxide (KOH mounts revealed fungal elements in 39 cases while 40 cases showed fungus on Gram stained smears. Males (54.55% were more commonly affected than the females (45.45%. The age ranged from 18 to 82 years. Most common age group to be involved was 41-60 years. Predisposing risk factors were seen in 34 (77.27% cases. Most common findings on clinical examination were anterior chamber reaction and conjunctival injection seen in all the cases. Other common findings were stromal infiltration and hypopyon seen in 20 (45.45% and 18 (40.91% cases respectively. On histopathological examination the fungus was typed, as aspergillus in 34 cases while no definite typing was possible in 10 cases. The predominant isolate was aspergillus flavus (59.09% followed by fusarium (15.91%. Mixed fungal and bacterial infection was seen in 3 (6.82% cases.CONCLUSION:Although culture is the gold standard for definitive diagnosis of fungal keratitis, direct microscopic examination of corneal scrapings or histomorphological evaluation of biopsies allow a rapid preliminary diagnosis. Early administration of antifungal treatment helps in preventing dreadful complications.

Other common findings were stromal infiltration and hypopyon seen in 20 (45.45%) and 18 (40.91%) cases respectively. On histopathological examination the fungus was typed, as aspergillus in 34 cases while no definite typing was possible in 10 cases. The predominant isolate was aspergillus flavus (59.09%) followed by fusarium (15.91%). Mixed fungal and bacterial infection was seen in 3 (6.82%) cases. CONCLUSION Although culture is the gold standard for definitive diagnosis of fungal keratitis, direct microscopic examination of corneal scrapings or histomorphological evaluation of biopsies allow a rapid preliminary diagnosis. Early administration of antifungal treatment helps in preventing dreadful complications.

Geothermal Exploration Case Studies on OpenEI (Presentation)  

Energy Technology Data Exchange (ETDEWEB)

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.

Ten Challenges for Decision Neuroscience  

Directory of Open Access Journals (Sweden)

Full Text Available Decision neuroscience research, as currently practiced, employs the methods of neuroscience to investigate concepts drawn from the social sciences. A typical study selects one or more variables from psychological or economic models, manipulates or measures choices within a simplified choice task, and then identifies neural correlates. Using this “neuroeconomic” approach, researchers have described brain systems whose functioning shapes key economic variables, most notably aspects of subjective value. Yet, the standard approach has fundamental limitations. Important aspects of the mechanisms of decision making – from the sources of variability in decision making to the very computations supported by decision-related regions – remain incompletely understood. Here, I outline ten outstanding challenges for future research in decision neuroscience. While some will be readily addressed using current methods, others will require new conceptual frameworks. Accordingly, a new strain of decision neuroscience will marry methods from economics and cognitive science to concepts from neurobiology and cognitive neuroscience.

String universality in ten dimensions  

CERN Document Server

We show that the N=1 supergravity theories in ten dimensions with gauge groups U(1)^{496} and E_8 x U(1)^{248} are not consistent quantum theories. Cancellation of anomalies cannot be made compatible with supersymmetry and abelian gauge invariance. Thus, in ten dimensions all supersymmetric theories of gravity without known inconsistencies are realized in string theory.

Leishmaniasis in dogs: Case study  

Directory of Open Access Journals (Sweden)

Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

Five case studies of multifamily weatherization programs  

Energy Technology Data Exchange (ETDEWEB)

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.

The author replies to a letter by Knox et al (Lancet, December 12 1987), discussing the problems of restricting radiation exposure during pregnancy. Dr. Mole suggests that when considering radiation exposures at known calendar dates, it may be more useful to derive gestational age by backwards extrapolation from the date of birth, as in studies of radiation-induced severe mental retardation and reduction in IQ in bomb survivors, rather than by studying tumour deaths in children in relation to timing of x-ray examinations by trimester.

Outage management: A case study  

International Nuclear Information System (INIS)

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

Radiative damping: a case study  

CERN Multimedia

We are interested in the motion of a classical charge coupled to the Maxwell self-field and subject to a uniform external magnetic field, B. This is a physically relevant, but difficult dynamical problem, to which contributions range over more than one hundred years. Specifically, we will study the Sommerfeld-Page approximation which assumes an extended charge distribution at small velocities. The memory equation is then linear and many details become available. We discuss how the friction equation arises in the limit of "small" B and contrast this result with the standard Taylor expansion resulting in a second order equation for the velocity of the charge.

Antiphospholipid syndrome: A case study  

International Nuclear Information System (INIS)

Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient''s high risk of strokes and hemorrhaging prompted investigation by a 99mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome

Frequency and antimicrobial resistance patterns of bacteria implicated in community urinary tract infections: a ten-year surveillance study (2000–2009  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Urinary tract infection (UTI is one of the most common infectious diseases at the community level. In order to assess the adequacy of the empirical therapy, the prevalence and the resistance pattern of the main bacteria responsible for UTI in the community (in Aveiro, Portugal was evaluated throughout a ten-year period. Methods In this retrospective study, all urine samples from patients of the District of Aveiro, in ambulatory regime, collected at the Clinical Analysis Laboratory Avelab during the period 2000–2009 were analysed. Samples with more than 105 CFU/mL bacteria were considered positive and, for these samples, the bacteria were identified and the profile of antibiotic susceptibility was characterized. Results From the 155597 samples analysed, 18797 (12.1% were positive for bacterial infection. UTI was more frequent in women (78.5% and its incidence varied with age, affecting more the elderly patients (38.6%. Although E. coli was, as usual, the most common pathogen implicated in UTI, it were observed differences related to the other bacteria more implicated in UTI relatively to previous studies. The bacteria implicated in the UTI varied with the sex of the patient, being P. aeruginosa a more important cause of infection in men than in women. The incidence of the main bacteria changed over the study period (P. aeruginosa, Klebsiella spp and Providencia spp increased and Enterobacter spp decreased. Although E. coli was responsible for more than an half of UTI, its resistance to antibiotics was low when compared with other pathogens implicated in UTI, showing also the lowest percentage of multidrug resistant (MDR isolates (17%. Bacteria isolated from females were less resistant than those isolated from males and this difference increased with the patient age. Conclusions The differences in sex and age must be taken into account at the moment of empirical prescription of antimicrobials. From the recommended antimicrobials by the European Association of Urology guidelines, the first line drugs (pivmecillinam and nitrofurantoin and the alternative antibiotic amoxicillin-clavulanic acid (AMX-CLA are appropriate to treat community-acquired UTI, but the fluoroquinolones should not be suitable to treat male infections and the trimethoprim-sulfamethoxazole (SXT shall not be used in the treatment of UTI at this level.

Abstract in english BACKGROUND: Mohs surgery is one of the most effective treatments for basal cell carcinomas. The expansion of its concepts enabled developing other equally effective methods to check surgical margins, and the Munich method is an example. OBJECTIVES: To evaluate the effectiveness of the Munich method [...] of micrographic surgery in a ten-year cohort study. METHODS: Ninety-three patients with a total of 96 skin tumors were treated with the Munich method of micrographic surgery, taking part in a follow-up protocol, from May 1994 through July 2004. RESULTS: Of all tumors, 61.4% were recurrent, 42.3% were recurrent more than once, and 53% were of the sclerodermiform type. The mean larger diameter was 1.58cm, and the mean smaller diameter was 1.10cm. In 95% of the cases, total extirpation of the tumor was obtained in three stages. The most common site was nasal (46.3%), followed by periocular (18.9%) and frontal (11.5%). Two patients were lost in follow-up. Of the 96 operated tumors, only 11 had a follow-up time shorter than 2 years. Fifty-six patients were followed for at least 5 years, and 45 (47.3%) for over 6 years. A single relapse was observed, which took place in the sixth year of observation. CONCLUSION: The Munich method is an efficient method of micrographic surgery, as good as the Mohs method. This study provides further evidence that the concept of micrographic surgery must be broadened to surgical excision with microscopic margin control, rather than linking it exclusively to the term "Mohs micrographic surgery".

Este trabalho fornece mais um indício de que o conceito de cirurgia micrográfica deve ser ampliado para cirurgia microscopicamente controlada, e não ficar ligado estritamente ao termo cirurgia de Mohs.BACKGROUND: Mohs surgery is one of the most effective treatments for basal cell carcinomas. The expansion of its concepts enabled developing other equally effective methods to check surgical margins, and the Munich method is an example. OBJECTIVES: To evaluate the effectiveness of the Munich method of micrographic surgery in a ten-year cohort study. METHODS: Ninety-three patients with a total of 96 skin tumors were treated with the Munich method of micrographic surgery, taking part in a follow-up protocol, from May 1994 through July 2004. RESULTS: Of all tumors, 61.4% were recurrent, 42.3% were recurrent more than once, and 53% were of the sclerodermiform type. The mean larger diameter was 1.58cm, and the mean smaller diameter was 1.10cm. In 95% of the cases, total extirpation of the tumor was obtained in three stages. The most common site was nasal (46.3%, followed by periocular (18.9% and frontal (11.5%. Two patients were lost in follow-up. Of the 96 operated tumors, only 11 had a follow-up time shorter than 2 years. Fifty-six patients were followed for at least 5 years, and 45 (47.3% for over 6 years. A single relapse was observed, which took place in the sixth year of observation. CONCLUSION: The Munich method is an efficient method of micrographic surgery, as good as the Mohs method. This study provides further evidence that the concept of micrographic surgery must be broadened to surgical excision with microscopic margin control, rather than linking it exclusively to the term "Mohs micrographic surgery".

Eccrine Angiomatous Hamartoma: A Retrospective Study of 15 Cases  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Eccrine angiomatous hamartoma (EAH comprises a rare nevoid proliferation of normal eccrine glands and small blood vessels and occasionally otherelements in the middle and deep dermis with variable clinical manifestations.Case series have rarely been published except for case reports and literaturereviews. The aims of this article were to investigate the clinical and pathologic features of patients with EAH in Taiwan and to compare our resultswith the results of previous studies.Methods: A retrospective review of medical records and histopathological findings wasperformed on patients diagnosed with EAH in a medical center in Taiwanbetween 1994 and 2010.Results: Fifteen patients with pathologically diagnosed EAH were collected. Themean age at the time of diagnosis was 38.6 years (range, birth to 67 years.The male to female ratio was 3 to 2. In most cases, EAH arose as a singlelesion on a lower extremity. The symptoms and signs most commonly associated with EAH were pain (60%, hypertrichosis (13.3%, itching (13.3%and hyperhidrosis (6.7%. Additional pathological findings included hemangioma (13.3%, verrucous hemangioma (6.7%, arteriovenous malformation(6.7%, and angiokeratoma (6.7%. None of the patients experienced spontaneous regression of the lesions before excision. Excisions were done in onepatient under general anesthesia, and ten patients with local anesthesia. Fourpatients were kept under observation. Tumor recurrences were noted in twoout of the eleven patients whose lesions were excised.Conclusion: Compared with cases in the literature, we found additional histopathologicalfindings and an increased tumor recurrence risk in our cohort. EAH remainsa benign and uncommon hamartomatous condition. Further multi-center, retrospective studies with larger case numbers are needed to better characterizethe disease presentation in Asian populations.

Ground-source heat pump case studies and utility programs  

Energy Technology Data Exchange (ETDEWEB)

Ground-source heat pump systems are one of the promising new energy technologies that has shown rapid increase in usage over the past ten years in the United States. These systems offer substantial benefits to consumers and utilities in energy (kWh) and demand (kW) savings. The purpose of this study was to determine what existing monitored data was available mainly from electric utilities on heat pump performance, energy savings and demand reduction for residential, school and commercial building applications. In order to verify the performance, information was collected for 253 case studies from mainly utilities throughout the United States. The case studies were compiled into a database. The database was organized into general information, system information, ground system information, system performance, and additional information. Information was developed on the status of demand-side management of ground-source heat pump programs for about 60 electric utility and rural electric cooperatives on marketing, incentive programs, barriers to market penetration, number units installed in service area, and benefits.

Teaching Business Demography Using Case Studies.  

Science.gov (United States)

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

External radiotherapy prior to thyroid cancer: A case-control study  

International Nuclear Information System (INIS)

The aim of this investigation was to study previous radiotherapy of malignant diseases as a risk factor for thyroid cancer. By using the Swedish Cancer Registry all cases of thyroid cancer with another malignant disease at least one year previously and living within the catchment area of the hospital were traced. During 1959-1989 a total of 1056 cases of thyroid cancer were identified. Of these, 37 had had another previous malignant disease and they constituted the cases in this study. As controls four persons with at least two malignant diseases, thyroid cancer excluded, were selected for each case from the same cancer registry. Ten (27.0%) of the 37 patients with thyroid cancer as a second tumor had earlier been irradiated with the treatment dose including the thyroid gland as compared with 34 (24.5%) of the 139 control patients. Eight of the ten cases with previous irradiation of the thyroid gland had papillary cancer. The median latency was 13 years. The estimated radiation dose in the thyroid varied between 3 and 40 Gy. External radiotherapy gave a crude odds ratio of 1.1 with 95% confidence interval = 0.5-2.8 for thyroid cancer. The weighted odds ratio was calculated to 2.3 with confidence interval = 0.5-8.9. This case-control study gave a nonsignificantly increased odds ratio for thyroid cancer in patients with external radiotherapy including the thyroid gland. 26 refs., 4 tabs

Mining Product Data Models: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents two case studies used to prove the validity of some data-flow mining algorithms. We proposed the data-flow mining algorithms because most part of mining algorithms focuses on the control-flow perspective. First case study uses event logs generated by an ERP system (Navision after we set several trackers on the data elements needed in the process analyzed; while the second case study uses the event logs generated by YAWL system. We offered a general solution of data-flow model extraction from different data sources. In order to apply the data-flow mining algorithms the event logs must comply a certain format (using InputOutput extension. But to respect this format, a set of conversion tools is needed. We depicted the conversion tools used and how we got the data-flow models. Moreover, the data-flow model is compared to the control-flow model.

Implementing Product Platforms: A Case Study  

DEFF Research Database (Denmark)

The paper describes a case study dealing with the process of creating and implementing a product platform. The paper espessially deals with the fact that to obtain the benefits of platforms a permanent change in behaviour in product development must be ensured. This change in behaviour requires acceptance and approval from the organisation in general and the commitment from management to enforce agreed-upon decisions. The case study itself was performed in the Danish company LEGO Group. The case study had two objectives: To create a technical architecture and align this architecture with the manufacturing setup; And to create procedures for using and maintaining the system and getting the commitment and approval of the platform.

Compactified vacuum in ten dimensions  

International Nuclear Information System (INIS)

Since the 1920's, theories which unify gravity with the other fundamental forces have called for more than the four observed dimensions of space-time. According to such a theory, the vacuum consists of flat four-dimensional space-time described by the Minkowski metric M4 and a compactified space B. The dimensions of B are small, and the space can only be observed at distance scales smaller than the present experimental limit. These theories have had serious difficulties. The equations of gravity severely restrict the possible choices for the space B. The allowed spaces are complicated and difficult to study. The vacuum is furthermore unstable in the sense that a small perturbation causes the compactified dimensions to expand indefinitely. There is an addition a semi-classical argument which implies that the compactified vacuum by annihilated by virtual black holes. It follows that a universe with compactified extra dimensions could not have survived to the present. These results were derived by applying the equations of general relativity to spaces of more than four dimensions. The form of these equations was assumed to be unchanged by an increase in the number of dimensions. The authors illustrate the effect of such terms by considering the example B = S6 where S6 is the six-dimensional sphere. Only when the extra terms are included is this choice of the compactified space allowed. He explore the effect of a small perturbation on such a vacuum. The ten-dimensional spherically symmetric potential is examined, and I determine conditions under which the formation of virtual black holes is forbidden. The examples M4 x S6 is still plagued by the semi-classical instability, but this result does not hold in general. The requirement that virtual black holes be forbidden provides a test for any theory which predicts a compactified vacuum

Study of interdiffusion in GaAsSbN/GaAs quantum well structure by ten-band k.p method  

Science.gov (United States)

The effect of annealing on the photoluminescence (PL) in GaAsSbN/GaAs quantum wells (QWs) grown by solid-source molecular-beam epitaxy has been investigated. The annealing time and temperature are 5 min and 650-750 °C, respectively. Low-temperature (4 K) PL peaks shift to higher energies with the annealing temperatures. An As-Sb atomic interdiffusion at the heterointerface is proposed to model this effect. The compositional profile of the QW after interdiffusion is described by an error function distribution and calculated by a ten-band k.p method. The estimated interdiffusion constants D are ~10-17-10-16 cm2/s in the above temperature range and an activation energy of 1+/-0.4 eV is obtained.

Case study: two fatal case reports of acute yohimbine intoxication.  

Science.gov (United States)

Yohimbine is an alkaloid that has been encountered on the streets as an aphrodisiac, hallucinogen, dietary supplement and erectile dysfunction drug. Yohimbine hydrochloride is an alpha 2-adrenoreceptor antagonist, blocking the pre- and postsynaptic alpha-2 adrenoreceptors and causing an increased release of noradrenaline and dopamine. An average oral dose of 5-15 mg produces a therapeutic whole blood level range of 40-400 ng/mL. Overdoses leading to neurotoxic effects have been seen with blood concentrations up to 5,000 ng/mL. The laboratories from the Maricopa County Medical Examiner and the Los Angeles County Department of Coroner each encountered a case in which yohimbine was identified in whole blood by means of a liquid-liquid basic drug extraction with detection on a GC-MS. Because validated quantitative methods for yohimbine did not exist at either facility, both agencies referred the blood specimens to NMS Labs, Inc. The reference laboratory analyzed the blood specimens with an LC-MS-MS and determined the quantitative values of yohimbine to be 7,400 and 5,400 ng/mL. Given the absence of other significant positive findings and the substantial yohimbine blood concentrations cited, the respective Medical Examiners determined the cause of death to be acute yohimbine intoxication with the mode being an accident. Yohimbine is a rarely encountered drug in medical examiner casework, and interpretation of the results is difficult to assess toward the cause and manner of death without such case studies being described.

Estudio de diez años sobre variedades de tumores de parótida en pediatría Ten-year study on varieties of parotid tumors in pediatrics  

Directory of Open Access Journals (Sweden)

Full Text Available Los tumores de parótida en pediatría son infrecuentes, pues constituyen aproximadamente el 0,5 % de todos los cánceres. Se presentan, generalmente, como un aumento de volumen local y asintomático, otras veces se acompañan de dolor y signos inflamatorios. Se realizó un estudio retrospectivo, longitudinal y descriptivo, para determinar la frecuencia y formas de presentación de los tumores de parótida diagnosticados en pacientes con edades comprendidas de 0 a 18 años, que han sido ingresados en el servicio de oncocirugía del Hospital "William Soler", entre febrero del año 2001 y diciembre de 2010, teniendo en cuenta: sexo, las formas de presentación, respuesta al tratamiento, así como las variantes histológicas presentadas, con el objetivo de dar a conocer estas variantes de tumores de parótida en pediatría, que, a pesar de ser infrecuentes, cuando se presentan constituyen un grupo de alto riesgo. Se diagnosticaron 7 pacientes, de los cuales 3 fueron adenomas pleomorfos, un adenocarcinoma, un carcinoma mucoepidermoide de la glándula, un linfoma de Hodgkin parotídeo y un tumor mixto con células atípicas de la glándula. El inicio de todos fue la presencia de una masa parotídea, en 6 de los casos asintomáticos, y en un caso con dolor local. Se le realizó ultrasonido de la glándula y biopsia aspirativa con aguja fina a todos los pacientes. El sexo masculino predominó sobre el femenino en una proporción 5 a 2, la edad media de presentación fue 12,3 años. La cirugía es el arma terapéutica principal en la mayoría de los casos. Se recomienda el seguimiento estrecho de los pacientes por el alto índice de recurrencia local.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.

Waiting Lists for Radiation Therapy: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Why waiting lists arise and how to address them remains unclear, and an improved understanding of these waiting list "dynamics" could lead to better management. The purpose of this study is to understand how the current shortage in radiation therapy in Ontario developed; the implications of prolonged waits; who is held accountable for managing such delays; and short, intermediate, and long-term solutions. Methods A case study of the radiation therapy shortage in 1998-99 at Princess Margaret Hospital, Toronto, Ontario, Canada. Relevant documents were collected; semi-structured, face-to-face interviews with ten administrators, health care workers, and patients were conducted, audio-taped and transcribed; and relevant meetings were observed. Results The radiation therapy shortage arose from a complex interplay of factors including: rising cancer incidence rates; broadening indications for radiation therapy; human resources management issues; government funding decisions; and responsiveness to previous planning recommendations. Implications of delays include poorer cancer control rates; patient suffering; and strained doctor-patient relationships. An incompatible relationship exists between moral responsibility, borne by government, and legal liability, borne by physicians. Short-term solutions include re-referral to centers with available resources; long-term solutions include training and recruiting health care workers, improving workload standards, increasing compensation, and making changes to the funding formula. Conclusion Human resource planning plays a critical role in the causes and solutions of waiting lists. Waiting lists have harsh implications for patients. Accountability relationships require realignment.

Clinical and radiographic outcomes of acetabular impaction grafting without cage reinforcement for revision hip replacement: a minimum ten-year follow-up study.  

Science.gov (United States)

Impaction bone grafting for the reconstitution of bone stock in revision hip surgery has been used for nearly 30 years. Between 1995 and 2001 we used this technique in acetabular reconstruction, in combination with a cemented component, in 304 hips in 292 patients revised for aseptic loosening. The only additional supports used were stainless steel meshes placed against the medial wall or laterally around the acetabular rim to contain the graft. All Paprosky grades of defect were included. Clinical and radiographic outcomes were collected in surviving patients at a minimum of ten years after the index operation. Mean follow-up was 12.4 years (sd 1.5) (10.0 to 16.0). Kaplan-Meier survival with revision for aseptic loosening as the endpoint was 85.9% (95% CI 81.0 to 90.8) at 13.5 years. Clinical scores for pain relief remained satisfactory, and there was no difference in clinical scores between cups that appeared stable and those that appeared radiologically loose. PMID:24493183

Impact of heavy metal pollution on forests. A case study of Gusum, Sweden  

Energy Technology Data Exchange (ETDEWEB)

During the past ten years the National Swedish Environment Protection Board has supported ecological studies on the impact of heavy-metal pollution on coniferous forest ecosystems. This report concludes studies on the effects of deposited copper and zinc, emitted from an isolated brassworks, on vegetation, soil biological and biochemical processes and the diversity, abundance and performance of soil fauna and microflora. The Gusum case study is probably the most comprehensive work of this kind ever performed on a forest ecosystem polluted by heavy metals.

Transcultural Nursing: Basic Concepts and Case Studies  

Science.gov (United States)

Created by the nonprofit organization Transcultural Nursing, this very useful website covers both basic concepts related to diversity as well as providing an array of case studies designed to help students, nurses and anyone practicing in the health professions better understand cultural diversity. The case studies are nicely designed, divided by general cultural community (Hispanic, Middle Eastern, Deaf, Asian, Afro American and Migrant Worker) with basic information about religion(s) or other demographic information that might relate to that particular group. Following the general information are three or four case studies illustrating specific instances where cultural differences came into play in a nursing or medical situation. The site also has an introductory area, which outlines some basic concepts including defining terms such as, cultural values and ethnocentrism. A page dedicated to the topic of third world nursing offers insight into this type of hands on experience in nursing in diverse communities, and a list of references and related links round out this very useful site.

Case study research designs: their place in chiropractic  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Case studies involve utilizing a distinct research approach. They are often confused with case reports, case series, cases used in rounds, and cases without control groups or baseline measures. The case study approach can provide a way to investigate broad chiropractic issues, policies, or practices in their real settings. Case study research designs are appropriate in both clinical and nonclinical settings. They require good conceptual skills not elaborate equipment; extensive “thinking”...

HYDROGEOLOGICAL RELATIONS ON KARSTIFIED ISLANDS - VIS ISLAND CASE STUDY  

Directory of Open Access Journals (Sweden)

Full Text Available An approach to the hydrogeological investigations on Adriatic islands is presented on the Island of Vis case study. Infiltration, accumulation and discharge of the groundwater occur in karstified rock mass. Hydrogeological relations are mostly a consequence of the geological setting, because of the complete hydrogeologic barrier in Komiža bay, and relative barrier in the area of karst poljes. Significant research was performed in the 1999 – 2000 period aimed of better understanding of hydrogeological relations. These investigations, as well as reinterpretation of some previously known data, included structural geology, hydrogeology, hydrology and hydrochemistry. Approximate rock mass hydraulic conductivity calculation is also shown, as well as level of its usability in such terrain. Based on all these methods, it is possible to conclude that on the Island of Vis there is no saline water present underneath the entire island. There is only a saline water wedge which is formed on the top of relatively impermeable base rock, some few tens of meters under recent sea level. With such a model, and taking in account the hydrological balance, it is possible to conclude that there is possibility of higher amount of groundwater exploitation then it is today.

Capturing Cultural Glossaries: Case-study II  

Directory of Open Access Journals (Sweden)

Full Text Available

ABSTRACT: This case-study attempts to present a brief glossary of Northern Sotho medical terms. It is a follow-up of a similar case-study (Madiba, Mphahlele and Kganyago 2003, which was an attempt to capture and present Northern Sotho cooking terms. Case-study I consists of the names for utensils, ingredients and the processes involved in the preparation of cultural dishes. With both these case-studies, the intention has been to use the opportunities availing themselves for the pres-ervation and valorisation of Northern Sotho, including the extension of its corpora to support national dictionary-making processes. The case-study methodology has been very useful for the purposes of this project and the context within which it was undertaken. It aims to provide a model for the collection and presentation of authentic Northern Sotho terminology which otherwise would hardly have been accessible.

Extraskeletal mesenchymal chondrosarcoma: an imaging review of ten new patients  

Energy Technology Data Exchange (ETDEWEB)

Extraskeletal mesenchymal chondrosarcoma (EMC) is a rare soft-tissue tumor that most arises in young adults. Because of its rarity, few imaging studies have been reported to date. The purpose of this study was to elucidate the imaging features of this tumor. We conducted a multi-institutional study in cooperation with five referral cancer centers in Japan. Imaging findings of ten new EMC cases, including conventional radiography, computed tomography (CT), and magnetic resonance imaging (MRI), performed at each institute, were reviewed along with clinical features. Ten patients with EMC, who had been treated at each hospital from 1990 to 2001, participated in this study. Soft-tissue masses with well-demarcated, dense and granular calcification were most frequently observed on plain radiographs and CT scans. T2-weighted MR images most clearly depicted a two-component structure composed of calcified and uncalcified areas, and enhanced MRI showed inhomogeneous enhancement in both areas. Although the sensitivity and specificity of these findings are unknown, they might be characteristic and have diagnostic value for this rare tumor. (orig.)

Terahertz applications in cultural heritage: case studies  

Science.gov (United States)

Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.

Case studies in organic contaminant hydrogeology  

International Nuclear Information System (INIS)

The effective management of domestic solid waste and hazardous, toxic, and radioactive waste is a major problem in the area of environmental geology and water sciences throughout the world. A series of case studies is presented of organic contaminants from both solid and hazardous waste disposal facilities to provide examples of these problems. The facilities were investigated to determine risks and liabilities before acquisition, to determine the site hydrogeologic conditions for design of appropriate groundwater monitoring plans, and/or to determine the potential for groundwater contamination. The case studies are of disposal facilities located in glacial tills, carbonaceous weathered clay soils, weathered shale, limestone bedrock, dolomite bedrock, and alluvial and sedimentary deposits. The results of these studies and investigations show certain relationships in the distribution of organic pollutants to the different geologic and hydrogeologic characteristics of each facility. In each of the four case studies, all 129 priority pollutants were analyzed in private wells and/or monitoring wells. The 31 volatile organic compounds (VOCs) of the priority pollutant list were the majority of organic compounds detected. When VOCs are found in groundwater impacted by disposal facilities, they are present in groups and tend to be distributed in patterns based on their relative concentrations. It is rare to find only one or two VOCs from facilities where leakage has been detected. The ethylenes and ethanes appear to be more prevalent and mobile than aromatic VOCs. The aromatics are restricted primarily to leachates and wastes and in monitoring wells located adjacent to facilities. 2 refs., 15 figs

Ten principles and ten commandments of radiation protection  

Energy Technology Data Exchange (ETDEWEB)

For decades, the phrase {open_quotes}time, distance, and shielding{close_quotes} has been presented as summarizing the {open_quotes}basics{close_quotes} of radiation protection. Indeed, for protection from external radiation sources, these three principles are probably the most important ones on which a worker can make decisions and take actions. However, these principles do not address protection against intakes of radioactive materials or {open_quotes}ontakes{close_quotes} (skin contamination), other risk-limiting measures, or other important protective measures taken by governments, public health agencies, regulators, and institutional programs (measures such as performance standards, health education, facility engineering requirements, and administrative procedures). I have identified ten principles and ten accompanying commandments of radiation protection: time, distance, dispersal, source reduction, source barrier, personal barrier, decorporation, effect mitigation, optimal technology, and limitation of other exposures. Corresponding non-technical forms of the commandments are hurry (but don`t be hasty); stay away from it; disperse it and dilute it; use as little as possible; keep it in; keep it out; get it out or off of you (after intake or skin contamination); limit the damage; choose the best technology (perhaps a non-radiation technology); and don`t compound risks (don`t smoke). Technical versions of the commandments are also provided using the verbs {open_quotes}optimize,{close_quotes} {open_quotes}maximize,{close_quotes} or {open_quotes}minimize.{close_quotes} Not all commandments can be applied at the same time, and application may be different for workers and members of the public. Advantages, disadvantages, and implementation of these principles and commandments are discussed, and numerous examples provided. The application of the principles and commandments must be based on knowledge of the radiological conditions to be managed. 4 refs., 1 tab.

Case studies in using alternative sampling technologies  

International Nuclear Information System (INIS)

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

Environmental qualification - facilities and case studies  

Energy Technology Data Exchange (ETDEWEB)

The term environmental qualification is used for assurance or guarantee for satisfactory performance of hardware under specified environmental conditions including normal, abnormal and accident conditions. To generate confidence about satisfactory performance in reasonable time, hardware must be tested under accelerated conditions. For testing and measuring performance parameters, it is essential to have adequate facilities and experienced and inquisitive staff so that qualified and reliable hardware can be manufactured by active participation of manufacturers, users and researchers. Top priority is given to the determination of characteristics, capabilities and limitations of hardware before really starting accelerated testing so that maximum information can be extracted before failure of hardware. This paper describes test and measurement facilities set up at the Bhabha Atomic Research Centre for environmental qualification and some case studies where it has been possible to make significant contributions towards reliability assessment, upgradation and indigenisation. Apart from climatic test facilities (thermal and humidity chambers), a Loss Of Coolant Accident (LOCA) environment simulator and synergistic simulator (combined environment test facility comprising temperature, humidity, gamma radiation and electrical stresses for studying interaction effects) have been set up. Notable case studies are :(1) Assessment of residual life-spans of cables and elastomeric components, (2) Reliability upgradation of indicating alarm meters and solenoid valves, (3) Assessment of survival capability of process instruments under LOCA environment, (4)Assessment of reusability of relays exposed to smoke and water spray in fire incident in a nuclear power station.

Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.

Flock of Dodos is a provocative film about intelligent design (ID) complete with animation and argumentative debates along with interviews with pleasant people from Kansas and Pennsylvania, the latest battlefields of the ID debate. The film does not resolve the issues, but it dramatically and sensitively displays them in a humorous manner. The film reminds those of us who would push the scientific agenda with polemics against laypeople of the world that this approach will hardly lead to their conversion. Less lecturing and more case studies on the ID topic are the only ways to deal reasonably with this issue.

Wind to Hydrogen in California: Case Study  

Energy Technology Data Exchange (ETDEWEB)

This analysis presents a case study in California for a large scale, standalone wind electrolysis site. This is a techno-economic analysis of the 40,000 kg/day renewable production of hydrogen and subsequent delivery by truck to a fueling station in the Los Angeles area. This quantity of hydrogen represents about 1% vehicle market penetration for a city such as Los Angeles (assuming 0.62 kg/day/vehicle and 0.69 vehicles/person) [8]. A wind site near the Mojave Desert was selected for proximity to the LA area where hydrogen refueling stations are already built.
