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.

Full Text Available This .study is a retrospective study of 10 patients with early gastric cancer, (6 from Imam Khomeini hospital between 1985 to 1994 and 4 from private office . from the standpoint of clinical and pathological views, treatment modalities and prognosis. In Imam Khomcni hospital early gastric cancer comprises near l'7t, (6/560 of all gastric cancers, which may he due to late reference, lack of screening procedures, etc. Mean age of onset was 52 years and male /'female ratio was 7:3. All patients had some type, of gastrointestinal upset like heartburn, epigastric pain etc. Six tumors were located in antrum and 3 in fundus and one was not identified. Macroscopically 4 cases were type Hc, two cases type Ha.two cases type Hb and two were type HI. 5 cases had only mucosa! involvement and 5 had both mucosal and submucosal involvement. In 6 patients the. tumor was undifferentiated, one moderately differentiated and 3 well differentiated. Intestinal metaplasia was found in 5 and gastritis in 9 of them. Only one patient had lesser curvature lymph node metastasis. Subtotal gastrectomy was perfnnncd for 8' and total gastrectomy for two patients. Except for one patient who died 24 hours after surgery due to Ml, 8 others lived disease free for more than or near 5 years after treatment. It is concluded that early diagnosis of cancer through screening procedures results in a better outlook for these patients.

Adolescent cancer patients' perspectives on their educational experiences: Ten case studies  

Science.gov (United States)

The goal of this study was to explore the educational experiences of adolescent cancer patients in treatment for cancer and enrolled in hospital, homebound, or community schools. The incidence of students who have or had cancer is becoming more prevalent in schools today because of increases in the population, the incidence rate of cancer, and the survival rate of cancer. The number of students surviving cancer has increased over 41% in the past ten years and underscores the importance of assuring an excellent education to children and adolescents with cancer so that they may enjoy a good quality of life as long-term survivors. This study explored the educational experiences of students who were adolescent cancer patients and identified educational and psychosocial issues important to their success. The goal of this research effort was to provide educators and medical staff with a deeper understanding of the unique psychoeducational needs of this population and to provide a foundation for developing ideas for improving the educational programs and support available to students who continue their middle and high school education while undergoing treatment for cancer. Participants included ten cancer patient whose mean age at onset of disease was 13.8 +/- 1.7 years, and mean age at interview was 15.2 +/- 1.8 years. The researcher conducted individual, in-depth, ethnographic interviews of students, and one parent and one teacher of each student. Case studies of the students included extensive dialogue of each of the contributing participants. An analysis of the case studies was conducted by coding emerging themes so that topics could be fully explored and compared between individuals, groups of individuals, and educational settings to identify the meaning that these students placed on the educational and psychosocial issues that they voiced as important. Advantages and disadvantages of each educational situation, homebound, hospital school, and community school, were compared. Psychosocial issues related to education were discussed. Additional findings included information about student computer use and information gathering, and the effects of cancer treatment on student interest in science and future occupational plans.

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.

A clinical study on ten cases of superior mesenteric arterial occulusion  

International Nuclear Information System (INIS)

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

Enabling frameworks for low-carbon technology transfer to small emerging economies: Analysis of ten case studies in Chile  

International Nuclear Information System (INIS)

Technology transfer is crucial to reduce the carbon intensity of developing countries. Enabling frameworks need to be in place to allow foreign technologies to flow, to be absorbed and to bring about technological change in the recipient country. This paper contributes to identifying these enabling factors by analysing 10 case studies of low-carbon technology transfer processes based in Chile. Our findings show the importance of strong economic and institutional fundamentals, a sound knowledge base, a sizable and stable demand and a functioning local industry. Policy recommendations are derived to improve the penetration of foreign low-carbon technologies in developing countries, focusing on the particularities of small and medium emerging economies. - Highlights: ? We analyse 10 case studies of low carbon technology transfer to Chile. ? We identify enablers of technology transfer to developing countries. ? We provide policy recommendations focusing on small and medium economies.

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.

Angioleiomyoma: magnetic resonance imaging features in ten cases  

Energy Technology Data Exchange (ETDEWEB)

Angioleiomyoma is a rare, benign smooth muscle tumour arising from the tunica media of small veins and arteries and can occur anywhere in the body. The histological appearances are well documented, but there are relatively few descriptions of the magnetic resonance imaging (MRI) findings. A retrospective study of the clinical presentation, MRI appearances and histological findings of ten angioleiomyomas presenting as extremity soft tissue masses. MRI typically demonstrated a well-defined, oval mass located superficial to the fascia with the commonest sites being the hand (three cases) and ankle/foot (five cases). The lesion was isointense to muscle on T1-weighted spin echo images with heterogeneous increased internal T2W/short tau inversion recovery (STIR) signal intensity, which commonly appeared as multiple linear or branching areas of hyperintensity. Enhancement after IV gadolinium ranged from diffuse to heterogeneous. In a single case, central fat signal intensity was seen, while a further case showed marked T2W/STIR hypointensity due to diffuse hyalinisation within the lesion. This is the largest reported MRI series of extremity musculoskeletal angioleiomyoma. Angioleiomyoma should be considered in the differential diagnosis of a superficial mass in the hand or foot, particularly when characteristic linear or branching hyperintensity is seen on T2W or STIR images.

Firework injuries: a ten-year study.  

Science.gov (United States)

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

Cancer profile in Kolar: A ten years study  

Directory of Open Access Journals (Sweden)

Full Text Available Context: Cancer profile varies in different regions and depends on race, lifestyle and diet. The study of a cancer profile helps to know the common cancers in a particular population, its probable risk factors and also helps in cancer control programs. AIM: To study the cancer profile at Kolar, based on Pathology Department records. Settings and Design: Retrospective study from January 1997 to December 2006. Materials and Methods: Cancer cases diagnosed by fine needle aspiration cytology (FNAC and histopathology in the Department of Pathology were included in the study. The relevant history, clinical findings, and sociodemographic information of each case was retrieved from hospital records. Statistical Analysis Used: Descriptive statistics. Results: Out of a total of 19,615 cases reported at the Department of Pathology, 2,744 (13.98% were cancer cases. The peak incidence was in the fifth decade in females and the seventh decade in males. Male : Female ratio was 0.7 : 1. Overall there was a steady rise in the number of cases from year 1997 to 2006. The top ten cancers in males were of oral cavity, stomach, esophagus, bone, non-Hodgkin?s lymphoma (NHL, prostate, liver, larynx, penis, and Hodgkin?s disease / bladder and those in females were oral cavity, cervix, breast, stomach, esophagus, thyroid, ovary, bone, rectum, and melanoma. Conclusions: Oral cavity and upper gastrointestinal cancers predominated in both genders. In females, cervical cancer predominated over breast cancer. Thyroid cancers were relatively more common in this region especially in females.

Gastric metastases. An endoscopic series of ten cases.  

Science.gov (United States)

We report a series of ten cases of the clinical, endoscopic and pathological features of gastric metastases. Patients were six women and four men between 54 and 88 years old, with gastric metastases from breast carcinoma (4), lung carcinoma (4) and melanoma (2). Patients underwent an upper gastrointestinal endoscopy for epigastralgia (2), hematemesis (2), dysphagia (1) and anemia (5). On endoscopy, tumors appeared as nodules with a central ulceration (5), an ulceration (4) or simulating linitis plastica (1). Metastases were located in the cardia (2), fundus (5) and antrum (3). Primary tumors had been diagnosed between one day and 20 years before upper endoscopy. Eight patients had multivisceral metastases. The microscopic features of the gastric metastases resembled a primary gastric cancer in eight cases. Thanks to clinical data, the pathologist confirmed the diagnosis of gastric metastases on immunohistochemistry. Nine patients died in the eight-month follow-up period. Gastric metastases are rare, occur at a late stage of the neoplastic disease, and have a poor prognosis. Diagnosis of gastric metastases is difficult because they simulate primary gastric cancer on endoscopy and on microscopic examination. A correct diagnosis is based on good communication between gastroenterologists and pathologists. PMID:20627637

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.

Optical Intraday Variability Studies of Ten Low Energy Peaked Blazars  

CERN Document Server

We have carried out optical (R band) intraday variability (IDV) monitoring of a sample of ten bright low energy peaked blazars (LBLs). Forty photometric observations, of an average of ~ 4 hours each, were made between 2008 September and 2009 June using two telescopes in India. Measurements with good signal to noise ratios were typically obtained within 1-3 minutes, allowing the detection of weak, fast variations using N-star differential photometry. We employed both structure function and discrete correlation function analysis methods to estimate any dominant timescales of variability and found that in most of the cases any such timescales were longer than the duration of the observation. The calculated duty cycle of IDV in LBLs during our observing run is ~ 52%, which is low compared to many earlier studies; however, the relatively short periods for which each source was observed can probably explain this difference. We briefly discuss possible emission mechanisms for the observed variability.

Iodine-131 metaiodobenzylguanidine scintigraphy for the location of neuroblastoma: preliminary experience in ten cases  

International Nuclear Information System (INIS)

Ten patients with histologically proven neuroblastoma were studied by [131I]MIBG scintigraphy. Tumor uptake of the radiopharmaceutical showed a spectrum varying from no uptake in one case, to slight uptake in two, moderate uptake in two and intense uptake in five cases. Iodine-131 MIBG scintigraphy was more effective in demonstrating the extent of neuroblastoma spread than were conventional bone scan and CT in one patient, equal to these modalities in four cases, almost equal in two cases and significantly inferior in three cases. These preliminary results suggest that [131I]MIBG scintigraphy is useful in detecting the presence and delineating the distribution of neuroblastoma and may, in certain cases, have therapeutic potential

Abstract in english CONTEXT: Primary central nervous system lymphomas (PCNSL) are a rare subgroup of lymphomas generally associated with HIV and EBV. OBJECTIVE: To study ten autopsy cases of PCNSL, to describe the neuropathological findings, to characterize the phenotype of the neoplastic cells, to detect EBV in the le [...] sion and to compare the findings with the clinical and laboratory data of the patients. METHOD: The clinical, histological and immunohistochemical data of ten cases of PCNSL, eight cases from patients with AIDS, identified among 265 autopsies of these patients were analyzed. RESULTS: Seven patients were males and the mean age was 40.9 years. The most frequent symptomatology was focal neurologic deficit (70%). Six patients presented with only one lesion. Histologically, densely cellular and polymorphous neoplasms with angiocentrism were observed, in 90% of cases. An association with other diseases was observed in four cases. Most patients had diffuse large B cell non-Hodgkin’s lymphoma. EBV was detected by immunohistochemistry in only one case. The lack of detection of the virus might have been due to the long time of fixation of the brain which might have inactivate epitopes therefore compromising the testing. CONCLUSION: In the present series, PCNSL presented with focal symptoms, with unifocal or multifocal lesions, with a predominant B-cell CD20 positive phenotype, rarely associated with EBV.

Abstract in english CONTEXT: Primary central nervous system lymphomas (PCNSL) are a rare subgroup of lymphomas generally associated with HIV and EBV. OBJECTIVE: To study ten autopsy cases of PCNSL, to describe the neuropathological findings, to characterize the phenotype of the neoplastic cells, to detect EBV in the le [...] sion and to compare the findings with the clinical and laboratory data of the patients. METHOD: The clinical, histological and immunohistochemical data of ten cases of PCNSL, eight cases from patients with AIDS, identified among 265 autopsies of these patients were analyzed. RESULTS: Seven patients were males and the mean age was 40.9 years. The most frequent symptomatology was focal neurologic deficit (70%). Six patients presented with only one lesion. Histologically, densely cellular and polymorphous neoplasms with angiocentrism were observed, in 90% of cases. An association with other diseases was observed in four cases. Most patients had diffuse large B cell non-Hodgkin’s lymphoma. EBV was detected by immunohistochemistry in only one case. The lack of detection of the virus might have been due to the long time of fixation of the brain which might have inactivate epitopes therefore compromising the testing. CONCLUSION: In the present series, PCNSL presented with focal symptoms, with unifocal or multifocal lesions, with a predominant B-cell CD20 positive phenotype, rarely associated with EBV.

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

Use of interactive lecture demonstrations: A ten year study  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

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.

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.

Mature cystic teratomas (MCT) with atypical MR findings. Ten cases with comparison of MR, CT, and pathologic features  

International Nuclear Information System (INIS)

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

Ten cases of metastatic cervical cancer with the treatment of permanent 125I seeds interstitial implants  

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)

Central nervous system cladosporiosis: An account of ten culture-proven cases  

Directory of Open Access Journals (Sweden)

Full Text Available Background : Central nervous system (CNS cladosporiosis is a rare infection caused by Cladophialophora bantiana. It has varied presentation and poor outcome. Most of the available data in the literature are reviews of individual case reports. Objective : To describe the clinical, radiological and mycological features of 10 cases of C. bantiana managed at a single tertiary center. To analyze the various treatment options, factors associated with outcome, and to review the relevant literature. Materials and Methods: This is a retrospective study of 10 patients with CNS cladosporiosis managed at National Institute of Mental Health and Neurosciences from 1979 to 2006. It is a descriptive study. The case records were reviewed for clinical presentation, radiological features, management and outcome. Only those patients in whom the fungus could be isolated on culture were included in the study. Results : The age of the patients ranged from three to 42 years. Nine patients presented with features of space-occupying lesion and one patient with chronic meningitis. There were no specific clinical or radiological features. None of patients had impaired immune status. This infection presented as two pathomorphological forms - diffuse meningoencephalitis and focal abscesses. Burr hole tapping and excision are the surgical options. Both patients with burr hole tapping required excision of abscess subsequently. Two out of seven patients with abscess expired compared to all three patients with diffuse meningoencephalitis who expired. Recurrences occurred in four of the five patients following excision of the abscess. Combination antifungal treatment had better result than monotherapy. The outcome was poor with survival of only 50%. Conclusions : Thorough microbiological examination is required to diagnose CNS infection caused by C. bantiana . The outcome is better in patients with abscess. Excision of the abscess followed by combination antifungal therapy results in better outcome. Close follow-up is required due to high risk of recurrence.

Imported malaria: a retrospective study in University Hospital, Kuala Lumpur, a ten-year experience.  

Science.gov (United States)

Over a period of ten years (1983-1992), 134 malaria cases admitted to University Hospital, Kuala Lumpur (UHKL) were analysed. Malays constituted 27.6%, Chinese 29.8%, Indians 9.7%, Indonesians 16.4% and other foreigners 16.4%. Therefore, of the total number of cases, foreigners constituted 32.8% (44) of all the malaria cases admitted to UHKL. Fifteen of these foreigners had chloroquine-resistant strains of malarial parasites. Three species of malaria were reported of which Plasmodium falciparum constituted the most (46.3%) (80% of these developed resistance to chloroquine). Plasmodium vivax was confirmed in 44.8% (10% of these developed resistance to chloroquine) and there was only one case of Plasmodium malarie infection. PMID:10968130

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

Modified posterior pelvic exenteration for advanced ovarian cancer: ten-year experience in 17 resectable cases  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To assess safety, efficacy and impact on survival of low anterior en bloc resection (modified posterior pelvic exenteration as part of optimal debulking for primary advanced ovarian cancer. Methods: Complete follow-up data were available for 17 patients who underwent this surgical procedure for advanced ovarian cancer between January 1996 and June 2006. The median age was 58 years (24 to 77. All had epithelial cancer. Seven patients underwent primary debulking, and ten patients underwent interval debulking. All patients underwent optimal cytoreduction (less than 1 cm residual disease and received postoperative platinum-based chemotherapy. Rresults: The postoperative mortality was 0%, while the overall major morbidity was 23.52% (n = 4. Residual disease after debulking was less than 1 cm in four patients, and was microscopic in 13 patients. The overall three-year survival rate was 76.47%, and the median survival time was 32 months. Cconclusions: When necessary, low anterior en bloc resection (modified posterior pelvic exenteration should not be an obstacle against optimal surgery. The morbidity rate was high, but the mortality rate was 0%. Long-term survival may ensue from this approach.

Ten-year follow-up of giant basilar aneurysm treated by sole stenting technique: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction The sole stenting technique has emerged as a new tool for the management of intracranial aneurysms. However, several concerns have emerged about the long-term behavior of intracranial stents, particularly their safety and efficacy. Case presentation We present the first case of an intracranial aneurysm intentionally treated with the sole stenting technique. After ten years of clinical and imaging follow-up, the lesion has healed and no intrastent stenosis is observed. Several issues concerning this technique are discussed. For instance, the modification of the angle and intra-aneurysmal thrombosis may account as positive effects; negative outcomes include in-stent thrombosis or stenosis. Conclusions This case report, involving a long clinical and imaging follow-up, provides an example of the effectiveness, safety, durability and simplicity of the sole stenting technique in the management of intracranial aneurysms.

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. Conclusion It can be concluded that treated oral cancer patients were neutropenic and prone to secondary infection of microbes. The medicinal plant can prove as effective antimicrobial agent to check the secondary infections in treated cancer patients.

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.

A pilot study on using acupuncture and transcutaneous electrical nerve stimulation (TENS to treat knee osteoarthritis (OA  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The present study tests whether a combined treatment of acupuncture and transcutaneous electrical nerve stimulation (TENS is more effective than acupuncture or TENS alone for treating knee osteoarthritis (OA. Methods Thirty-two patients with knee OA were randomly allocated to four groups. The acupuncture group (ACP received only acupuncture treatment at selected acupoints for knee pain; the TENS group (TENS received only TENS treatment at pain areas; the acupuncture and TENS group (A&T received both acupuncture and TENS treatments; the control group (CT received topical poultice (only when necessary. Each group received specific weekly treatment five times during the study. Outcome measures were pain intensity in a visual analogue scale (VAS and knee function in terms of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC. Results The ACP, TENS and A&T groups reported lower VAS and WOMAC scores than the control group. Significant reduction in pain intensity (P = 0.039 and significant improvement in knee function (P = 0.008 were shown in the A&T group. Conclusion Combined acupuncture and TENS treatment was effective in pain relief and knee function improvement for the sampled patients suffering from knee OA.

Meta-analysis of genome-wide association studies identifies ten loci influencing allergic sensitization.  

DEFF Research Database (Denmark)

Allergen-specific immunoglobulin E (present in allergic sensitization) has a central role in the pathogenesis of allergic disease. We performed the first large-scale genome-wide association study (GWAS) of allergic sensitization in 5,789 affected individuals and 10,056 controls and followed up the top SNP at each of 26 loci in 6,114 affected individuals and 9,920 controls. We increased the number of susceptibility loci with genome-wide significant association with allergic sensitization from three to ten, including SNPs in or near TLR6, C11orf30, STAT6, SLC25A46, HLA-DQB1, IL1RL1, LPP, MYC, IL2 and HLA-B. All the top SNPs were associated with allergic symptoms in an independent study. Risk-associated variants at these ten loci were estimated to account for at least 25% of allergic sensitization and allergic rhinitis. Understanding the molecular mechanisms underlying these associations may provide new insights into the etiology of allergic disease.

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.

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

Directory of Open Access Journals (Sweden)

Full Text Available 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 results and atmospheric measurements performed during several cruise campaigns performed aboard the Research Vessel (RV URANIA of the CNR over the Mediterranean sea basin. RGM concentrations have been modelled using a photochemical box model of the MBL and compared to measured data obtained during the research cruises. The comparison results supports the hypothesis that there are daytime mercury oxidation reactions occurring which have not yet been identified. Major findings of key studies carried out during ten years of ship-borne activities have been highlighted.

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

Directory of Open Access Journals (Sweden)

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

Study of the tolerance of ten accessions of carrot (Daucus carota L. to salinity  

Directory of Open Access Journals (Sweden)

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

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.

Carbon Monoxide Poisoning: from the Perspective of Ten Years and 2417 Cases  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: Carbon monoxide (CO poisoning is a common problem in various countries, especially in Winter months. CO exposure results in the formation of carboxyhemoglobin (COHb, which is responsible for toxicity symptoms. In this study, we aim to demonstrate the demographic features and seasonal variations of this particular public health problem. Materials and Methods: We retrospectively evaluated hospital police reports and medical records of 2417 ED patients diagnosed with CO poisoning between 1999 and 2009. Sources of exposure, seasonal variation and demographic characteristics were analyzed. Results: The mean age of the patients, of whom 1418 (58.7% were female, was 29±18 years. While 1708 patients (70.7% were admitted to adult ED, 709 (29.3% patients were admitted to pediatric ED. January and subsequent Winter months represented the most dangerous periods for CO exposure. No intentional (suicidal attempt exposure to CO intoxication was reported and the major cause for intoxication included unsecured stoves and gas heaters. Conclusion: Emergency physicians should be familiar with symptoms and remedies of CO intoxication, which still constitutes a serious health problem.

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Hemicrania continua (HC) é uma cefaléia primária relativamente incomum primeiramente descrita enquanto sindrome em 1984. Por ser relativamente rara, sua apresentação clínica ainda carece de melhor descrição. O objetivo do presente estudo é apresentar e criticamente discutir as principais característ [...] icas clínicas de 10 pacientes com HC consecutivamente vistos em um centro de atendimento especializado. Todos os pacientes apresentavam cefaléia estritamente unilateral, sem alternância de lado e com absoluta resposta a indometacina. Sete pacientes (70%) apresentavam sinais autonômicos durante a exacerbação da dor. Quatro (40%) apresentavam sintomas migranosos durante as exacerbações e um apresentava alívio parcial com diidroergotamina. Um paciente apresentava exacerbações excruciantemente severas. Embora as principais características da HC - dor continua, unilateral, responsiva à indometacina - permaneçam extremamente associados à sindrome, um refinamento na caracterização clínica é necessário. Abstract in english 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.

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

Ten-year fatal and non-fatal myocardial infarction incidence in elderly populations in Spain: the EPICARDIAN cohort study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background In Spain, more than 85% of coronary heart disease deaths occur in adults older than 65 years. However, coronary heart disease incidence and mortality in the Spanish elderly have been poorly described. The aim of this study is to estimate the ten-year incidence and mortality rates of myocardial infarction in a population-based large cohort of Spanish elders. Methods A population-based cohort of 3729 people older than 64 years old, free of previous myocardial infarction, was established in 1995 in three geographical areas of Spain. Any case of fatal and non-fatal myocardial infarction was investigated until December 2004 using the "cold pursuit method", previously used and validated by the the WHO-MONICA project. Results Men showed a significantly (p Conclusion Incidence of fatal and non-fatal myocardial infarction is high in the Spanish elderly population. Men show higher rates than women, but gender differences diminish with age.

Element analysis and biological studies on ten oriental spices using XRF and Ames test.  

Science.gov (United States)

Ten oriental spices were analyzed for their element composition using X-ray fluorescence (XRF): nutmeg (Myristica fragrans), coriander (Coriandrum sativum), safflower (Carthamus tinctorius), caraway (Carum carvi), Sicilian sumac (Rhus coriaria), aniseed (Anisum vulgare), black pepper (Piper nigrum), cardamom (Elettaria cardamomum), cumin (Cuminum cyminum) and nigella (Nigella sativum). The spices were found to contain the following elements: Mg, Al, Si, P, S, Cl, K, Ca, Ti, Mn, Fe, Cu and Zn, with varying concentrations. Mutagenic studies using Salmonella typhimurium strains TA97a, TA98, TA100, and TA102 showed that the above spices have no base pair substitution mutagenic activity. However, a weak frameshift mutagenicity has been shown by nutmeg and a very weak oxidative mutagenic action has been revealed by cumin. PMID:14531636

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

Directory of Open Access Journals (Sweden)

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

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.

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.

Case Study: Trigger Cases Versus Capstone Cases  

Science.gov (United States)

Is it better to use a case at the beginning of a topic or at the end? To answer this, we need to examine both trigger and capstone cases in terms of their goals. The answer is not so inscrutable--it clearly depends upon your goal. Both trigger and capstone cases have their place, but the author would contend that if you wish to really engage a student in a subject, one can hardly do better than to start with an interesting, current, and controversial topic. And even if you sneak in a bunch of scientific lingo that initially doesn't make sense, a trigger case can surely prompt a student to want to learn more about the topic. And that is one heck of a great way to begin a day.

Tetanus in a rural setting of South-Western Nigeria: a ten-year retrospective study.  

Science.gov (United States)

We review the records of 79 tetanus patients in two hospitals (one tertiary and one secondary level) in Owo, Ondo state, Nigeria from 1997 to 2006. The male: female ratio was 3:1. Ages were 14-70 years (mean 33.25 years, SD ±16.76). The overall case fatality rate (CFR), 32.91%, did was not significantly different in the two hospitals. CFR for men was 32.10% and for women 35.29%. The main factor indicative of bad prognosis was a short hospitalization period. It was observed that 30.38% of our patients were discharged against medical advice (DAMA), that financial constraint was the underlying problem in 50% of cases, and that the trend of DAMA occurred at the two study sites. This DAMA phenomenon could pose a great danger to the eradication of this vaccine preventable disease in rural areas. PMID:21483514

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.

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.

Chemonucleolysis versus open discectomy. A ten-year follow-up study.  

Science.gov (United States)

Retrospectively 156 patients with an average follow-up period of 10.3 years were classified in two groups. Group I, 85 patients, chose chymopapain as their primary treatment. Group II, 71 patients, elected to have a laminectomy with discectomy. Overall, 98% of patients responded to follow-up investigations. Based on several well-accepted pain outcome measures there were no significant differences between the two groups at ten years. Recurrence rates, however, were greater following open discectomy at one- and ten-year follow-up examination. The question of when to return a patient to work yielded interesting results. Those patients returning to work before feeling completely recovered from symptoms had a poorer outcome at final follow-up examination. PMID:3708992

Early detection, early symptom progression and symptomatic remission after ten years in a first episode of psychosis study  

DEFF Research Database (Denmark)

Background: Poor symptom outcome remains a challenge in psychosis: At least 50% of first-episode patients continue to have positive and/or negative symptoms after ten years. Objective: To investigate rates, early predictors and early symptom progression of long-term non-remitted psychosis in an early detection study. Methods: Symptomatic remission according to new international criteria was assessed in 174 patients at ten-year follow-up. Remitted and non-remitted patients were compared on early symptom progression, and logistic regression was applied to predict non-remission. Results: At ten years, 50% of patients were in symptomatic remission. Non-remission was predicted by positive symptoms at inclusion and during the first year of treatment. Of individual symptoms only hallucinations were significantly predictive of ten-year non-remission. Early symptom differences were not reflected by differences in treatment. Conclusions: Long-term symptomatic non-remission is associated with early positive symptoms. More assertive intervention may be needed in patients who do not respond robustly in the first year of treatment, whether or not they have been detected “early”.

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.

Human chorionic gonadotropin and human placental lactogen in extragonadal tumors. An immunoperoxidase study of ten non-germ cell neoplasms.  

Science.gov (United States)

The immunoperoxidase localization of the alpha and beta subunits of human chorionic gonadotropin (hCG) and of human placental lactogen (hPL) was studied in ten extragonadal nontrophoblastic tumors associated with raised serum levels of one or more of these placental proteins. Three of the tumors were bronchial carcinomas, one was a gastric carcinoma, two were malignant carcinoids (one bronchial and one gastric), two were pancreatic islet cell carcinomas, and two were metastatic carcinomas with an unknown primary site. The maximum alpha subunit serum level was 33,000 ng/ml (gastric carcinoid), the maximum hCG/hCG-beta level was 705,000 ng/ml, and the maximum hPL level was 50 ng/ml (both in the gastric carcinoma). An indirect immunoperoxidase technique and rabbit polyclonal affinity-purified antibodies and peroxidase conjugates were used on formalin-fixed, paraffin-embedded sections. Five blocks (eight cases) or six blocks (two cases) from various sites were obtained from each patient at surgery and/or autopsy. Positive stains for hCG/hCG-beta were seen in six of seven tumors (25/37 blocks) with raised levels, for the alpha subunit in nine of nine tumors (30/47 blocks), and for hPL in two of five tumors (4/26 blocks). Only a relatively minor number of the cells were positive, and within the same case, there was considerable site-to-site variation in the number of positive cells. Large bizarre cells contained hCG/hCG-beta as well as the alpha subunit, if it was demonstrated in the same tumor as the beta subunit. Otherwise, the alpha subunit was found in small unremarkable cells. Giant cells that were smaller than those positive for hCG/hCG-beta contained in hPL. In some serial sections, hCG-alpha, hCG/hCG-beta, and hPL were segregated in different cell populations, supporting the concepts of their separate genetic control. PMID:2413978

Study on dose distributions in a slab phantom irradiated by several tens MeV neutrons  

International Nuclear Information System (INIS)

From the viewpoint of radiation protection for high and intermediate energy radiation fields such as accelerator facilities, it is important to evaluate the effective dose due to secondary neutrons produced. As for the effective dose evaluation, the accuracy of high energy particle transport code system, however, has not been validated experimentally for intermediate energy neutrons. To establish a method of effective dose evaluation due to several tens MeV neutrons, neutron fluxes and dose distributions in a slab phantom were measured with SSNTDs (Solid State Nuclear Track Detectors), fission counter, TEPC and TEIC using 40- and 65-MeV quasi-monoenergetic neutrons at TIARA of JAERI. The measured distributions were compared with the calculated ones with the HETC-3STEP and MORSE-CG codes. In addition, for the purpose of applying them to the dose evaluation, the energy spectra of source neutrons and energy responses of detectors were determined. As a result, the calculated distributions of neutron flux and absorbed dose within the phantom were in good agreement with the experimental ones, and those of dose equivalent agreed with the measured ones within about 20%. It was found that the effective dose for several tens MeV neutrons could be evaluated with the accuracy of about ±20%. Source spectra below 10 MeV were evaluated from the present measurements and calculations. The evaluated ones will be very useful for future experiments and calculations in TIARA because they have not been measured. The energy responses of SSNTDs were evaluated for neutrons of wide energy range, based on the newly developed computation code and the measured responses for neutrons ranging from 100 keV to 65 MeV.

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.

Flash Flood Case Studies  

Science.gov (United States)

This module takes the learner through seven case studies of flash flood events that occurred in the conterminous U.S. between 2003 and 2006. The cases covered include: * 30-31 August 2003: Chase & Lyon Counties, KS * 16-17 September 2004: Macon County, NC * 31 July 2006: Santa Catalina Mountains near Tucson, AZ * 25 December 2003: Fire burn area near San Bernardino, CA * 30 August 2004: Urban flash flood in Richmond, VA * 19-20 August 2003: Urban flash flood in Las Vegas, NV * 9 October 2005: Cheshire County, NH This module assists the learner in applying the concepts covered in the foundation topics of the Basic Hydrologic Sciences course. Some of the specific topics pertinent to these cases are the physical characteristics that make a basin prone to flash floods, basin response to precipitation, flash flood guidance (FFG), the relationship between wildfire and flash floods, and the relationship between urban development and flash floods. Related topics brought out in the cases include radar quantitative precipitation estimation (QPE), the National Weather Service Flash Flood Monitoring and Prediction (NWS FFMP) products, debris flows, impounded water, and interagency communications. The core foundation topics are recommended prerequisite materials since this module assumes some pre-existing knowledge of hydrologic principles. In particular, the Runoff Processes and Flash Flood Processes modules contain material directly related to these cases.

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)

Study of liver cirrhosis over ten consecutive years in Southern China  

Science.gov (United States)

AIM: To investigate the etiology and complications of liver cirrhosis (LC) in Southern China. METHODS: In this retrospective, cross-sectional study, we identified cases of liver cirrhosis admitted between January 2001 to December 2010 and reviewed the medical records. Patient demographics, etiologies and complications were collected, and etiological changes were illustrated by consecutive years and within two time periods (2001-2005 and 2006-2010). All results were expressed as the mean ± SD or as a percentage. The ?2 test or Student’s t-test was used to analyze the differences in age, gender, and etiological distribution, and one-way analysis of variance was applied to estimate the trends in etiological changes. We analyzed the relationship between the etiologies and complications using unconditioned logistic regression, and the risk of upper gastrointestinal bleeding (UGIB) and hepatocellular carcinoma (HCC) in the major etiological groups was evaluated as ORs. A P value less than 0.05 was considered significant. Statistical computation was performed using SPSS 17.0 software. RESULTS: In this study, we identified 6719 (83.16%) male patients and 1361 (16.84%) female patients. The average age of all of the patients was 50.5 years at the time of diagnosis. The distribution of etiological agents was as follows: viral hepatitis, 80.62% [hepatitis B virus (HBV) 77.22%, hepatitis C virus (HCV) 2.80%, (HBV + HCV) 0.58%]; alcohol, 5.68%; mixed etiology, 4.95%; cryptogenic, 2.93%; and autoimmune hepatitis, 2.03%; whereas the other included etiologies accounted for less than 4% of the total. Infantile hepatitis syndrome LC patients were the youngest (2.5 years of age), followed by the metabolic LC group (27.2 years of age). Viral hepatitis, alcohol, and mixed etiology were more prevalent in the male group, whereas autoimmune diseases, cryptogenic cirrhosis, and metabolic diseases were more prevalent in the female group. When comparing the etiological distribution in 2001-2005 with that in 2006-2010, the proportion of viral hepatitis decreased from 84.7% to 78.3% (P China is viral hepatitis. However, the proportions of viral hepatitis and HBV are gradually decreasing. Alcoholic LC patients exhibit a greater risk of experiencing UGIB, and HBV LC patients may have a greater risk of HCC.

Coastal Management case study  

Science.gov (United States)

To prepare for the case study, lecture material on coastal landforms and processes is presented. Particular attention is paid to barrier islands, such as the Outer Banks. During the lecture, typical coastal engineering structures, such as groins, breakwaters, and jetties, are introduced. The case study is introduced with a brief overview of North Carolina's coastal management laws, Figure Eight Island's geography, and the current controversy over whether to build a terminal groin. Students are then broken down into small groups and presented with two opposing editorials. The groups are instructed to try to come to consensus as to whether the terminal groin should be allowed or disallowed or to suggest a third alternative. After approximately 25 minutes, each group informally reports out to the rest of the class.

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.

Computational study of the structural and vibrational properties of ten and twelve vertex closo-carboranes  

Energy Technology Data Exchange (ETDEWEB)

Calculations using ab initio Hartree-Fock and Density Functional theories, the latter employing the B3LYP functional, in combination with a number of large standard basis sets ranging from 6-31G** to cc-pVDZ, have been performed on a series of ten and twelve vertex closo-carborane isomer species. Results obtained for optimized structural parameters and molecular properties are presented for 1,2-, 1,6- and 1,10-C{sub 2}B{sub 8}H{sub 10} and 1,2-, 1,7- and 1,12-C{sub 2}B{sub 10}H{sub 12} and compared, where possible, with both earlier theoretical data and experiment. Irrespective of the model chemistry chosen, the para-isomer in each class of carborane cluster is found to be the most stable species, corresponding to a structure in which the cage carbon atoms are positioned at diametrically opposed ends of the respective polyhedron. Boron-hydrogen and carbon-hydrogen bond lengths are found to change little on going from isomers of one particular cage size to another, supporting analogous conclusions previously established for small closo-carborane cages possessing five, six and seven vertices. The calculated vibrational spectra of the isomers of both decacarborane and dodecacarborane are seen to be similar to each other and reflect a high degree of rigidity within each cluster. Key polyhedral skeletal breathing modes along with characteristic boron-hydrogen and carbon-hydrogen stretching frequencies are identified in the spectra and compared with experiment. Thermochemical data relating to each species are also analyzed.

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.

Ten year progressive ventricular enlargement in schizophrenia: an MRI morphometrical study.  

Science.gov (United States)

Recent studies of the brain using magnetic resonance imaging (MRI) have suggested progressive structural changes in schizophrenics. However, those studies were conducted over periods of less than 5 years and thus lacked sufficient capacity to determine the course and nature of this process. In this study, MRI scans were obtained in 15 schizophrenics and 12 controls at baseline and after 4- and 10-year follow ups. Volumes of the lateral ventricles were measured. Patients were assessed by the Brief Psychiatric Rating Scale (BPRS) at the same two time points: at baseline and at 10-year follow up. After 10 years, a significant lateral ventricular enlargement was found in patients (mean percentage change: +22.9%) but not in controls (5.1%). Although our results are not in disagreement with the neurodevelopmental hypothesis, they do provide strong evidence that in schizophrenia progressive brain reduction occurs even in its chronic stage.

A ten-year follow-up study of cotton textile workers.  

Science.gov (United States)

A follow-up study of respiratory function in cotton textile workers was performed 10 yr after the original cross-sectional study (1975 to 1985). There were 35 nonsmoking female and 31 smoking male textile workers restudied from the original group of 116. The majority of those lost to follow-up had left the industry. The prevalence of byssinosis among the female workers at the time of follow-up was 15/35 (42.9%) compared with 8/35 (22.9%) at the time of the initial study (p = 0.063). For men the byssinosis prevalence at follow-up was 16/31 (51.6%) compared with 8/31 (22.9%) at the time of the initial study (p = 0.03). Similarly, the prevalence of almost all other respiratory symptoms was significantly higher at the follow-up than at the time of the initial study. Significant across-shift decrements in FEV1 and FVC were documented at both surveys. The mean annual decline in ventilatory capacity was greater than expected for both female (FVC: -0.036 +/- 0.005 L/yr; FEV1: -0.059 +/- 0.009 L/yr) and male workers (FVC: -0.059 +/- 0.008 L/yr; FEV1: -0.068 +/- 0.006 L/yr) (Mean +/- SE). The mean total airborne dust concentration measured at the time of the follow-up study was 3.95 mg/m3 with an average respirable dust concentration of 0.97 mg/m3. We conclude that continued exposure to high dust concentrations in the cotton textile industry is associated with an increasing prevalence of respiratory symptoms and progressive impairment of lung function. The increase in respiratory impairment was seen both in smokers and nonsmokers. PMID:1990943

Pathologic Assessment of Meckel’s Diverticulum Specimens; A Ten Year Study  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Meckels diverticulum is one of the most common congenital anomalies of gastrointestinal tract. Our aim was to study pathologic features of surgical specimens of the diverticulum and to assess the type of lining mucosa, presence of Helicobacter pylori and inflammatory changes. Methods: We studied patients medical records and pathology files of the years 1994 through 2004, of the patients who underwent surgery with the diagnosis of Meckels diverticulum in Childrens Medical Center, Tehran. Pathologic features such as length and lining of the diverticulum and other variables such as age, gender and clinical signs were studied. Findings: We found 45 specimens in this period (80% male 20% female. The mean age was 3.8 years (25 days to 11 years and most of the patients were between 2 to 4 years old (33.6%. Most common clinical symptoms were abdominal pain (17 and hematochesis (4; 20 patients had combined symptoms such as abdominal pain and melena. Only 9 patients with lower gastrointestinal bleeding had Technetium scan and all of them were positive. Associated findings during surgery included appendicitis and invagination. Twenty diverticulae were inflamed in pathologic report, 8 with gangrene and 5 with perforation. Pathologic examination of specimens revealed a mean diameter of 2 cm (range: 0.4-4.5 and a mean length of 3.8 cm (range: 1-10. Lining was of intestinal type in 27 (60%, gastric in 10 (22.2% and combined in 8 specimens (17.8%. 11 specimens from 18 that were lined by gastric type of mucosa showed no Helicobacter pylori in Giemsa stain (2 had mucosal necrosis. Conclusions: Clinical findings of Meckels diverticulum in our study were rather the same as in literature. The most efficient way of diagnosis was Technetium scan. Pathologic examination of specimens revealed that most diverticulae were lined by intestinal type of mucosa. None of those with gastric type of mucosa showed Helicobacter Pylori infection.

Ten-Year Cumulative Incidence of Diabetic Retinopathy. The Beijing Eye Study 2001/2011  

Science.gov (United States)

Objective To assess the cumulative 10-year incidence of diabetic retinopathy (DR) and its associated factors in a population living in Greater Beijing. Methods The population-based longitudinal Beijing Eye Study, which included 4439 subjects (age in 2001: 40+years) in 2001, was repeated in 2011 with 2695 subjects participating (66.4% of the survivors). The study participants underwent a detailed ophthalmic examination. Fundus photographs were examined for the new development of DR. Results After excluding individuals with DR at baseline (n?=?87) or no sufficient fundus photographs in 2011 (n?=?6), the study included 2602 subjects with a mean age of 64.6±9.7 years (median: 64.0 years; range: 50 to 93 years). In the 10-year period, 109 subjects (39 men) developed new DR with an incidence of 4.2% (95% confidence interval (CI): 3.45,5.03). In multiple logistic regression analysis, incident DR was significantly associated with higher HbA1c value (Pdiabetes mellitus (Pdiabetes mellitus, higher estimated CSFP and shorter axial length (Pdiabetes mellitus.

Reproduction and production in a buffaloes farm of the Marche region: a ten-year study  

Directory of Open Access Journals (Sweden)

Full Text Available Water buffalo milk reproductive and productive traits are fundamental to evaluate farm efficiency and dairy economy. Due to the buffalo cows’ long life these aspects are also important to assess the improvement of genetic animal potential and to reach optimal productive performance. Currently this knowledge is critical since the Italian cattle population is decreasing whereas the national buffalo sector is expanding; this trend is partially depending on the reconversion of some dairy cattle’ farms into buffalo cows’ farms. The present investigation was undertaken to study non-genetic factors affecting reproductive parameters and milk production traits in a farm located in a not traditional area for buffalo farming.

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

Science.gov (United States)

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

Study of thin-film silicon solar cells at irradiances above ten thousand suns  

International Nuclear Information System (INIS)

We used a tightly focused Gaussian beam of a HeNe laser to study accelerated light-induced degradation (Staebler-Wronski effect) and high photocarrier generation rates in amorphous and microcrystalline silicon thin-film solar cells, at up to13 MW/m2 irradiance. For the experiments, the spot radius was varied from a minimum of 8.6 ?m in the focus to around 1 mm away from the focus. According to COMSOL'' (registered) simulations, even at these high power densities heat diffusion into a glass substrate aided by spreading conduction via the Ag back-contact restricts the temperature rise to less than 14 K. Short-circuit current can be measured directly over a range of irradiances, and the J-V characteristic may be estimated by taking into account shunting by the inactive part of the cell.

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

International Nuclear Information System (INIS)

Monthly oxygen isotope data from seventeen precipitation stations and eleven river stations are presented for the years 1978-1985. The spatial and temporal variations are described by period mean ?18O values and amplitudes of the seasonal component. The irregular fluctuations superimposed on the seasonal variation are studied. Whilst distance dependent correlations between stations are found there are no significant correlations to temperature or atmospheric moisture content on a monthly time-scale. Relations between precipitation input and river water output are discussed in terms of mean ?18O shift and seasonal amplitude damping. Estimates of mean residence times are also given. A fair agreement with what can be expected from simple catchment characteristics is obtained. (author). 6 refs, 8 figs, 3 tabs

Using a natural abilities battery for academic and career guidance: a ten-year study.  

Science.gov (United States)

Over a period of 10 years, first-year students from 11 consecutive veterinary classes conducted a self-assessment using a natural abilities survey. The present study analyzes the data compiled from students' self-assessment results. As a group, veterinary students are exceptional problem solvers, either through inductive or deductive reasoning, and have strong spatial relations capacities. Veterinary students have a range of learning styles with design memory being the primary vehicle for information delivery and tonal memory being the least frequently used style overall. Information gained on each student's natural abilities can be used to guide effective career decision making and enhance prospects for long-term career satisfaction. PMID:22023979

Apathy in first episode psychosis patients: a ten year longitudinal follow-up study  

DEFF Research Database (Denmark)

BACKGROUND: Apathy is a common symptom in first episode psychosis (FEP), and is associated with poor functioning. Prevalence and correlates of apathy 10 years after the first psychotic episode remain unexplored. OBJECTIVE: The aims of the study were twofold: 1) to examine prevalence and predictors of apathy at 10 years, and 2) to examine the relationship between apathy at 10 years and concurrent symptoms, functioning and outcome, including subjective quality of life. METHODS: Three-hundred-and-one patients with FEP were included at baseline, 186 participated in the 10 year follow-up. Of these, 178 patients completed the Apathy Evaluation Scale (AES-S-Apathy). Patients were classified as having apathy (AES-S-Apathy?27) or not. The relationship between apathy and baseline variables (Demographics, Diagnosis, Duration of Untreated Psychosis), measures of symptomatology (Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia), functioning (Global Assessment of Functioning Scale, Strauss Carpenter Level of Functioning Scale) and subjective quality of life (Lehman's Quality of Life Interview) were estimated through correlation analyses and blockwise multiple hierarchical regression analysis. RESULTS: Nearly 30% of patients met the threshold for being apathetic at follow-up. No baseline variables predicted apathy significantly at 10 years. Apathy was found to contribute independently to functioning and subjective quality of life, even when controlling for other significant correlates. CONCLUSIONS: Apathy is a common symptom in a FEP cohort 10 years after illness debut, and its presence relates to impaired functioning and poorer subjective quality of life.

Goiania incident case study  

International Nuclear Information System (INIS)

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 asr 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

Severe allergic reactions to food in Norway: a ten year survey of cases reported to the food allergy register.  

Science.gov (United States)

The Norwegian Food Allergy Register was established at the Norwegian Institute of Public Health in 2000. 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.

Dioxin: a case study.  

Science.gov (United States)

The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

Trends in the theoretical and research methodological approaches applied in doctoral studies in information and knowledge management: an exploration of ten years of research in South Africa  

Directory of Open Access Journals (Sweden)

Full Text Available The past ten years have seen the field of information and knowledge management develop and implement new and improved technologies. Because of the ease with which information is exchanged the contribution to information overload has increased exponentially and the need for information and knowledge management is more real than ever before. Research in itself is a science of knowledge creation that continuously evolves in line with newly developed theories and research methodologies. An investigation of the theories and research methodologies that doctoral theses, completed in South Africa, ascribed to over the past ten years were conducted. Search strings containing 'information management', 'knowledge management' and 'information and knowledge management' were searched within citation, abstract and subject fields. A sample of 30 theses from a possible 47 in the relevant population was identified. Qualitative and mixed methods research design was favoured, making use of case studies and surveys, but paying little attention to theoretical approaches or paradigms. The boundaries between disciplines are continuously re-defined, new disciplines evolve and traditional disciplines suffer under the pressures of changing problems of the world. The importance of research in the field of information and knowledge management being grounded in the most recent scientific thought is emphasized.

Theoretical study on ten ?-S states of Si2- anion: Potential energy curves, spectroscopy and spin-orbit couplings  

Science.gov (United States)

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

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

Some of the specific topics pertinent to this case are soil conditions, the impact of QPF on runoff, runoff models, runoff processes, routed flow and stage-discharge relationships. Observations of upstream conditions and comparisons to historic crests are also examined to assist with operational flood forecast decisions. The core foundation topics are recommended as a prerequisite since this module assumes some pre-existing knowledge of hydrologic principles.

Theory testing using case studies  

DEFF Research Database (Denmark)

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

Ten years of progress in the Hokkaido birth cohort study on environment and children's health: cohort profile--updated 2013.  

Science.gov (United States)

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

Case Studies in Library Security  

CERN Document Server

This book employs a familiar vehicle in library literature—the case study—but in a departure from the expected, takes that time-honored genre into a new dimension. Shuman uses the conversational narrative as a vehicle for portraying 40 security and safety issues that may arise in libraries, disturbing or vexing patrons and library staff members, alike. Unlike the traditional narrative approach of other case study books, in this work, each case is presented as a soliloquy, within a fictional but plausible library situation, whereby the protagonist uses his or her own colorful mode of expression

The low contact stress mobile-bearing total knee replacement: a prospective study with a minimum follow-up of ten years.  

Science.gov (United States)

We have examined the outcome of 400 consecutive patients who underwent total knee replacement with the Low Contact Stress mobile-bearing system between 1993 and 1994 and were followed up for a minimum of ten years. All operations were performed by surgeons in Christchurch, New Zealand, who used no other knee prosthesis during the study time. At ten years after operation 238 patients (244 knees) remained for independent clinical and radiological assessment. There was a significant improvement (p knee scores at one, three, seven and ten years, although a slight deterioration in the score occurred between seven and ten years which did not reach statistical significance. The survival for polyethylene wear or loosening was 97% (95% CI 96 to 98) and survival using reoperation for any cause was 92% (95% CI 90 to 94) at 12 years. Polyethylene wear was more common in the meniscal-bearing component, with five knees requiring revision and a further eight demonstrating early wear. Osteolysis was not seen in the rotating platform component, but was present in three of the meniscal-bearing knees. There was no association between the radiological alignment at one year and those knees that subsequently required revision. However, there was an association between the overall limb alignment and the Western Ontario McMasters University score (p mobile-bearing total knee replacement has proved to be a reliable implant at ten years when used in primary knee replacement irrespective of the deformity and diagnosis.

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.

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 mly 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

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.

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

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

Digital Repository Infrastructure Vision for European Research (DRIVER)

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

The “what” and “how” of case study rigor: Three strategies based on published research  

Digital Repository Infrastructure Vision for European Research (DRIVER)

To provide evidence-based strategies for ensuring rigor of case studies, we examine what rigor types authors report and how they report them by content-analyzing all case studies published 1995-2000 in ten management journals. Comparing practices in articles addressing rigor extensively and less extensively, we reveal three strategies for insuring rigor. First, very few case-study authors explicitly label the rigor criteria in terms of the concepts commonly used in the positivist tradition (c...

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

Organisational Communication: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available The organization chosen for this case study on organizational communication is a small political activists' organization for which the writer of this paper once volunteered. The organizational communication problem encountered was that the volunteer supervisor did not have projects ready during the scheduled volunteer time slots, and despite a thorough interview process to determine skill-need matches and prior verbal scheduling of volunteer times, this problem persisted for months. With the lack of a communication plan, the consequence was a diminished enthusiasm for the cause and growing level of frustration causing this writer to cease volunteering for the organization despite having a true belief in its mission.

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.

Malaria cases estimation measurement in ten municipalities of Nariño Pacific coast in 2009 Estimación del sub-registro de casos de paludismo en 10 municipios de la costa del Pacífico nariñense durante 2009  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. The complete and effective malaria cases data collection is an essential question to make operative plans, as well as to develop and apply preventive and control policies. However, in Colombia, not all identified cases are notified and not all of them are incorporated into the surveillance system. This underreport represents a serious issue to decision makers.
Objective. To estimate error type and quantity committed to complete the malaria individual cases notification form and its digitization level through the notification form use and monitoring, in ten municipalities of Nariño in 2009.
Materials and methods. This is a descriptive, transversal study with a no probabilistic and convenience diagnostic and treatment sites sample. From this sites notification forms copies were taken to compare case-by-case with the Public Health Surveillance System notification database. Proportions were calculated.
Results. From 2,816 positive cases notification forms it was showed that in more than 60% of cases information about residence municipality, origin municipality and occupation variables were not reported. Case-by-case comparison revealed that 845 (30.0% notification forms were not digitized at all. Information of variables such as residence municipality name and onset of symptoms date were neither complete nor exact in more than 50% of cases.
Conclusions. The use of notification forms with copy will reveal notification underreport due to lack of digitization. A third of cases should be recovered.
Introducción. La recolección de información completa y efectiva de casos de paludismo es fundamental para elaborar planes operativos, así como desarrollo y aplicación de políticas de prevención y control. Sin embargo, no todos los casos identificados son notificados y no todos son incorporados en el sistema de información. El sub-registro representa un problema para los tomadores de decisiones.
Objetivo. Estimar el tipo y cantidad de errores cometidos al llenar la ficha de notificación de casos de paludismo y su nivel de digitación mediante uso y seguimiento de la ficha de notificación en 10 municipios nariñenses durante 2009.
Materiales y métodos. Estudio descriptivo, transversal en muestra no probabilística, de conveniencia, de puestos de diagnostico y tratamiento. Se tomaron copias de fichas y de la base de datos de notificación del sistema de vigilancia y se efectúo comparación caso a caso. Se calcularon proporciones.
Resultados. Sobre 2.816 fichas de notificación de casos positivos, se evidenció que en más del 60% de los casos no se reporto información en las variables municipio de residencia, municipio de origen y código de ocupación. La comparación caso a caso mostró que 845 (30,0% fichas no fueron digitadas. La información de variables como nombre del municipio de residencia y fecha inicio de síntomas, no fueron completas, ni exactas en más del 50% de los casos.
Conclusiones. El empleo de fichas de notificación con copia permite conocer el sub-registro de la notificación debida a la falta de digitación. Una tercera parte de los casos pueden ser recuperados.

Childhood and adult tuberculosis in a rural hospital in Southeast Ethiopia: a ten-year retrospective study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Many DOTS experiences in developing countries have been reported. However, experience in a rural hospital and information on the differences between children and adults are limited. We described the epidemiology and treatment outcome of adult and childhood tuberculosis (TB cases, and identified risk factors associated with defaulting and dying during TB treatment in a rural hospital over a 10-year period (1998 to 2007. Methods Retrospective data collection using TB registers and treatment cards in a rural private mission hospital. Information was collected on number of cases, type of TB and treatment outcomes using standardised definitions. Results 2225 patients were registered, 46.3% of whom were children. A total of 646 patients had smear-positive pulmonary TB (PTB, [132 (20.4% children]; 816 had smear-negative PTB [556 (68.2% children], and 763 extra-PTB (EPTB [341 (44.8% children]. The percentage of treatment defaulters was higher in paediatric (13.9% than in adult patients (9.3% (p = 0.001. The default rate declined from 16.8% to 3.5%, and was independently positively associated with TB meningitis (AOR: 2.8; 95% CI: 1.2-6.6 and negatively associated with smear-positive PTB (AOR: 0.6; 95% CI: 0.4-0.8. The mortality rate was 5.3% and the greatest mortality was associated with adult TB (AOR: 1.7; 95% CI: 1.1-2.5, TB meningitis (AOR: 3.6; 95% CI:1.2-10.9, and HIV infection (AOR: 4.3; 95% CI: 1.9-9.4. Decreased mortality was associated with TB lymphadenitis (AOR: 0.24; 95% CI: 0.11-0.57. Conclusion (1 The registration of TB cases can be useful to understand the epidemiology of TB in local health facilities. (2 The defaulter and mortality rate of childhood TB is different to that of adult TB. (3 The rate of defaulting from treatment has declined over time.

Case Study: A Picture Worth a Thousand Words? Making a Case for Video Case Studies  

Science.gov (United States)

A picture, they say, is worth a thousand words. If a mere picture is worth a thousand words, how much more are "moving pictures" or videos worth? The author poses this not merely as a rhetorical question, but because she wishes to make a case for using videos in the traditional case study method. She recommends four main approaches of…

Powers of ten  

CERN Document Server

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. The camera then zooms back in to the picnic, and then to views of negative pow...

"Clicker" Cases: Introducing Case Study Teaching Into Large Classrooms  

Science.gov (United States)

Case study teaching is difficult in large classes, especially in fixed-seat ampitheaters. The development of audience response systems, or "clickers," for use in classrooms has opened up exciting new possibilities for creating and implementing interactive case studies, particularly in large introductory science courses.

Ten-year absolute risk of osteoporotic fractures according to BMD T score at menopause: the Danish Osteoporosis Prevention Study  

DEFF Research Database (Denmark)

In the non-HRT arms of the DOPS study, 10-year fracture risk was higher at each level of T score than predicted by the Kanis algorithm. Under-reporting of fractures in registers and inclusion of HRT users are probable explanations for inappropriately low fracture risk estimates for younger women. INTRODUCTION: International recommendations highlight the importance of absolute fracture risk in establishing intervention thresholds. The available estimates of long-term risk have been derived by combining relative risks from meta-analyses with U.S. normative BMD data and Swedish fracture incidence records. We validated the 2001 Kanis risk algorithm using incident fractures observed in untreated women in the first 10 years of the Danish Osteoporosis Prevention Study (DOPS). Comparisons were also made with the relative risks derived from a recent meta-analysis of 12 cohort studies. MATERIALS AND METHODS: We analyzed DXA of the spine and hip from 872 women who were enrolled in the non-hormone replacement therapy (HRT) arms of the study and had not received HRT, bisphosphonates, or raloxifene. We collected verified reports of fractures at each visit. We focused on fractures of the hip, spine, shoulder, and forearm to provide risks comparable with the Kanis algorithm. Accordingly, asymptomatic radiographic vertebral fractures were not included. RESULTS: Seventy-eight women (9%) sustained relevant fractures. The risk of fracture increased by 1.32 (95% CI, 1.02; 1.70) for each unit decrease in femoral neck T score and by 1.30 (95% CI, 1.06; 1.58) for each unit decrease in lumbar spine T score at baseline. Absolute fracture risk was higher than expected from the Kanis algorithm at all T score levels. The difference was greatest for participants in the higher range of T scores. At T = -1, the observed risk was 10.9% as opposed to an expected risk of 5.7%. Relative risk gradients were similar to those of the recent meta-analysis. CONCLUSIONS: In healthy women, examined in the first year or two after menopause, 10-year fracture risk was higher at each level of BMD T score than expected from the model by Kanis et al. Inclusion of HRT users in the cohorts used may have led to higher BMD values and lower absolute fracture risk in the Kanis model. These longitudinal data can be used directly in estimating absolute fracture risk in untreated north European women from BMD at menopause.

Longitudinal analysis of development among single and nonsingle children in Nanjing, China: ten-year follow-up study.  

Science.gov (United States)

In order to examine the impact of "one-child-per-couple" family planning policy on child development, a longitudinal study of a group of children in Nanjing, China, was carried out between 1984 and 1995. The same cohort of children was examined at four stages of development: preschool, early school, preadolescence, and adolescence. Achenbach's Child Behavior Checklist was used to measure the child's behavior. A total of 274 children were surveyed in all four stages. The total behavior problem scores obtained at different stages of development were compared among boys and girls. The results showed that the total score declined significantly in association with the time. As the child grew older, the problems score decreased significantly. This maturation effect was seen for both boys and girls. On average, boys' scores dropped from 21 to 11, whereas girls' scores went from 19.5 to 12. In comparing single with nonsingle boys, there were no significant differences throughout the four stages of development. However, girls who were single children, in contrast to girls with siblings, had significantly higher scores of total behavior problems at each stage of development. These findings illustrate that the longitudinal effect of being a "single-child" is similar to other studies, indicating a minimal impact of family policy. However, the effects were more prominent among girls. This phenomenon can be explained by parents' different attitude toward single-children because of gender difference. PMID:11048820

Personality Effects on Romantic Relationship Quality through Friendship Quality: A Ten-Year Longitudinal Study in Youths  

Science.gov (United States)

This study examined whether individuals with different personality types (i.e., overcontrollers, undercontrollers, resilients) had different friendship quality development throughout adolescence. It also investigated whether personality types were indirectly related to romantic relationship quality in young adulthood, via friendship quality development in adolescence. The study employed six waves of longitudinal questionnaire data from Dutch youths who had a romantic relationship when they were young adults. Two age cohorts were followed, from 12 to 21 years and from 16 to 25 years, respectively. Findings showed that resilients reported higher mean levels of friendship quality during adolescence (i.e., more support from, less negative interaction with and less dominance from their best friend) than both overcontrollers and undercontrollers. Through the mean levels of friendship quality throughout adolescence, resilients indirectly experienced higher romantic relationship quality during young adulthood than both overcontrollers and undercontrollers. Thus, results provide support for a developmental model in which adolescent friendship quality is a mechanism linking personality types with young adulthood romantic relationship quality.

Ten sessions of adjunctive left prefrontal rTMS significantly reduces fibromyalgia pain: a randomized, controlled pilot study.  

Science.gov (United States)

Transcranial magnetic stimulation (TMS) of the prefrontal cortex can cause changes in acute pain perception. Several weeks of daily left prefrontal TMS has been shown to treat depression. We recruited 20 patients with fibromyalgia, defined by American College of Rheumatology criteria, and randomized them to receive 4000 pulses at 10 Hz TMS (n=10), or sham TMS (n=10) treatment for 10 sessions over 2 weeks along with their standard medications, which were fixed and stable for at least 4 weeks before starting sessions. Subjects recorded daily pain, mood, and activity. Blinded raters assessed pain, mood, functional status, and tender points weekly with the Brief Pain Inventory, Hamilton Depression Rating Scale, and Fibromyalgia Impact Questionnaire. No statistically significant differences between groups were observed. Patients who received active TMS had a mean 29% (statistically significant) reduction in pain symptoms in comparison to their baseline pain. Sham TMS participants had a 4% nonsignificant change in daily pain from their baseline pain. At 2 weeks after treatment, there was a significant improvement in depression symptoms in the active group compared to baseline. Pain reduction preceded antidepressant effects. TMS was well tolerated, with few side effects. Further studies that address study limitations are needed to determine whether daily prefrontal TMS may be an effective, durable, and clinically useful treatment for fibromyalgia symptoms.

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

International Nuclear Information System (INIS)

esting feature observed in this work is the formation of axial jet-like structures which appears at late times almost hundred nanoseconds after pinch disruption. These structures are composed by a metallic plasma which results from ablation of the inner electrode. The mechanism responsible for the formation of this kind of structure is still unknown, although evidence suggests that the phenomena is not related to the pinch formation process. One of the principal motivations of this thesis was to study the optimization for neutron emission in the PF-50J device. This plasma focus is expected to yield 103-104 neutrons per pulse when is operated with deuterium. Standard detection techniques, for example neutron activation detectors, present detection limits higher than 105 neutrons per pulse, so it was necessary to develop a measurement method for higher efficiency detectors based on the use moderated proportional counter tubes for the purpose of neutron optimization. In contrast to low rate continuous regime, this detectors show pulse piling up when irradiated with pulsed neutrons, which make impossible to count events with standard nuclear electronics. In this thesis, it is presented a detailed study of pulsed piling up statistics in the proportional counter and a complete characterization of the 3He tubes based detection system. Regarding that the net area of detector output signal is proportional to the number of detected events, a counting model was developed and thus a methodology for measurement of the neutron yield is proposed. Special emphasis was put on the sources of fluctuation that affects the measurement process, which are given by the counting statistics, piling up statistics, and background electrical noise. As a result, the methodology allows measurements uncertainties for pulsed D-D fusion neutrons lower than 30% in the range of Y ? 3x103n/shot, reducing in this way by almost two order of magnitude the detection limit of the state of art techniques. A theoretical study of the detection frequency or reproducibility for pulsed neutron sources is also presented. Comparisons with results in PF-50J show that theoretical models for reproducibility are reasonable high boundary estimations for the experimental values. The optimization study is presented in the last part of this work. Optimal conditions for neutron emission were experimentally obtained. An interesting finding is the observation of two regimes for pinch formation and neutron emission. The first regime is related to the pinch formation close to the first current maximum in the first quarter of period, while in the second one these phenomena are observed at higher pressures close to the first current minimum in the second quarter of period, and even also close to the second current maximum in the third quarter of period. This behavior is linked to the formation of multiple plasma sheets over the insulator and to the energy coupling between generator and load. In connection to the laws governing the optimization for neutron emission for a plasma focus device, boundary values linking global optimal configuration, namely, effective anode length and pressure with other operation parameters as anode radii and current peak are proposed. The validity of this scheme is particularly proved for the optimization of the PF-50J device. Attention was also put on some engineering issues. There was found that neutron emission is strongly affected by impurities generated by electrode ablation. In connection to that, there was observed that gas removal cycle and geometry of the focus chamber are of supreme importance for high reproducibility emission neutron. There was also found that the neutron production is strongly affected when conditioned for plasma focus operation insulator is exposed by a long time to air in atmospheric conditions

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.

The association of microalbuminuria with mortality in patients with acute myocardial infarction. A ten-year follow-up study  

DEFF Research Database (Denmark)

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

Ten-year viability study on natural populations of Drosophila sibling species from Laguna Verde, Veracruz, México.  

Science.gov (United States)

The generation of electricity in nuclear power plants produces an increase in background radiation that could possibly have some impact on the organisms that live in that area. In order to identify and quantify any such possible effect, the natural populations of two sibling species, D. melanogaster and D. simulans, that live in the immediate vicinity of the first Mexican Nuclear Power Plant were analyzed for a period of 10 years. Collections of flies were made at two sites, one close to and one farther from the power plant, during the pre and operational stages of the reactor, and their egg-to-adult viability was analyzed. The data obtained indicate that in both sites, the egg-to-adult viability was generally higher in D. melanogaster than in D. simulans. Further, a relationship was found between egg-to-adult viability and the season of the year (warm-wet or cool-dry season). Some differences were found between the two sites. It may be concluded that there is no negative impact on the Drosophila populations studied. PMID:15106671

The following results were obtained during the period of 1970 to 1979-1980 in a study of 1040 Staphylococcus aureus strains in Belgium from cattle, poultry and pigs and 138 Staphylococcus hyicus strains from pigs, using the agar dilution technique and different penicillinase test methods: -- The incidence of penicillinase-positive strains increased in bovine and porcine S. aureus strains but decreased in poultry strains. From 1974 on more than 75% of S. aureus strains from cow udders produced penicillinase. -- The numbers of tetracycline-resistant strains steadily decreased during the period under investigation. -- Strains resistant to the macrolides and lincomycin were most frequent among S. hyicus and S. aureus strains from pigs isolated in 1973-1975. They were less numerous in 1979-1980. The inducible type of macrolide-resistance was found only among strains from poultry and cattle. In 1979-1980 strains resistant to lincomycin but susceptible to macrolide-antibiotics were detected. -- Two types of sensitivity to bacitracin were discovered: highly sensitive strains were frequent in cattle and rare in poultry. Intermediately sensitive strains dominated in poultry and pigs. These two groups of strains belonged to distinct chemotypes. Only one poultry strain was highly resistant to bacitracin. -- Number of neomycin-, sulphonamide- and chloramphenicol-resistant strains and strains resistant to the penicillinase-stable penicillins and cephalosporins were low and did not increase. -- Novobiocin resistance was only found among strains from broiler breeders and broilers. -- All strains tested were sensitive to the nitrofurans and related compounds (furazolidone, nitrovin), flavomycin, carbadox, trimethoprim, rifamycin and the virginiamycin combination.

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

Science.gov (United States)

Investigating the recovery capacity of wildlife populations following demographic crashes is of great interest to ecologists and conservationists. Opportunities to study these aspects are rare due to the difficulty of monitoring populations both before and after a demographic crash. Ebola outbreaks in central Africa have killed up to 95% of the individuals in affected western lowland gorilla (Gorilla gorilla gorilla) populations. Assessing whether and how fast affected populations recover is essential for the conservation of this critically endangered taxon. The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004. This allowed us to describe Ebola's short-term and long-term impacts on the structure of the population. The size of the population, which included around 380 gorillas before the Ebola outbreak, dropped to less than 40 individuals after the outbreak. It then remained stable for six years after the outbreak. However, the demographic structure of this small population has significantly changed. Although several solitary males have disappeared, the immigration of adult females, the formation of new breeding groups, and several birth events suggest that the population is showing potential to recover. During the outbreak, surviving adult and subadult females joined old solitary silverbacks. Those females were subsequently observed joining young silverbacks, forming new breeding groups where they later gave birth. Interestingly, some females were observed joining silverbacks that were unlikely to have sired their infant, but no infanticide was observed. The consequences of the Ebola outbreak on the population structure were different two years and six years after the outbreak. Therefore, our results could be used as demographic indicators to detect and date outbreaks that have happened in other, non-monitored gorilla populations. PMID:22649511

Ten Questions about Emergence  

CERN Document Server

Self-Organization is of growing importance for large distributed computing systems. In these systems, a central control and manual management is exceedingly difficult or even impossible. Emergence is widely recognized as the core principle behind self-organization. Therefore the idea to use both principles to control and organize large-scale distributed systems is very attractive and not so far off. Yet there are many open questions about emergence and self-organization, ranging from a clear definition and scientific understanding to the possible applications in engineering and technology, including the limitations of both concepts. Self-organizing systems with emergent properties are highly desirable, but also very challenging. We pose ten central questions about emergence, give preliminary answers, and identify four basic limits of self-organization: a size limit, a place limit, a complexity limit and finally a combinatorial limit.

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.

Roadmaster Roading Contractors Case Study  

Directory of Open Access Journals (Sweden)

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

[Hashimoto encephalopathy: a case study].  

Science.gov (United States)

The impact of thyroid hormones upon the proper function of central nervous system has been known for many years. The neurological symptoms and psychiatric disturbances may occur both in case of hypo- as well as hyperthyreosis. The encephalopathy Hashimoto (EH) described in this paper is a rare illness which occurs in case of patients suffering from the autoimmunological thyroid disease and increased level of antibodies in serum without any connections to the thyroid function. It is characterised by a variety of neurological symptoms and psychotic disturbances, acute state, high re-occurrence and good reaction to glicocorticosteroid treatment. Although we face encephalopathy Hashimoto extremely rarely in the clinical practice one should remember about it during the diagnostic process because when it is a long lasting untreated illness it may lead to the irreversible changes in the central nervous system.

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.

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.

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.

Use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using Poppen's approach: a report of ten cases and a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background There are several treatment approaches for pineal region meningiomas, such as Poppen's approach, Krause's approach and combinations of the two approaches. We present our experience with the use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using a suboccipital transtentorial approach (Poppen's approach and evaluate the role of Poppen's approach. Methods During the period from January 2005 to June 2010, ten patients presented to us with pineal region meningioma. MRI was routinely used to define the tumor size, position, and its relevant complications while 3D-CTA was applied to define the blood supply of the tumor and the venous complex (VC shift before operations. Most of the meningiomas had developed at both sides of the tentorial plane and extended laterally with typical characteristics of a pineal region tumor. Results All tumors were completely removed surgically without any injury to the VC. Postoperative intracranial infection occurred in one case who recovered after antibiotics were given. Postoperative intraventricular hemorrhage and pneumocephalus were found in one case, but fully recovered after conservative treatment. In the nine cases of concurrent hydrocephalus, this was gradually relieved in eight patients and the single case that became aggravated was successfully treated with ventriculoperitoneal shunt. Moreover, the follow-up MRI examinations did not indicate any recurrence of the meningiomas. Conclusion We found that the use of Poppen's approach is strongly supported for the successful removal of pineal region meningiomas without serious complications.

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.

Labyrinthine sequestrum: four case studies.  

Science.gov (United States)

Labyrinthine sequestrum, a rare form of labyrinthitis, is highly distinct from the more commonly encountered labyrinthitis ossificans based on its unique clinical, radiologic, and histologic characteristics. The study included 4 such patients who had undergone clinical and laboratory investigations, computed tomography (CT), and magnetic resonance imaging (MRI) assessments followed by surgical procedures and pathological evaluation. Their major symptoms were otorrhea, otalgia, tinnitus, and profound hearing loss. Imaging studies showed an osteolytic soft mass with calcified debris in the inner ear, and the bony labyrinth was eroded partly or completely by granulation mass, with loss of bony morphology. Further pathological examination was coincident with inflammatory granulation tissue with some calcification or osseous tissue. The disease process is attributed to chronic osteomyelitis due to the presence of osteonecrosis. Prompt CT and MRI examinations and optimal therapeutic management facilitate definitive diagnosis and protect against fatal complications. PMID:22467283

Linguistic Overgeneralization: A Case Study  

Directory of Open Access Journals (Sweden)

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

Disseminated granuloma annulare: study on eight cases.  

Science.gov (United States)

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

Ten percent of the patients were between 40 and 49 years of age, 20% between 50 and 59 years, 35% were between 60 and 69 years and 20% between 70 and 79 years of age. This may reflect a tradition of early drinking and smoking. Doctor's delay was the cause of delayed referral in 14% of the cases while 72% of the patients were the cause themselves for the delayed referral.

A network security case study  

International Nuclear Information System (INIS)

This paper reports on a study to validate the Graphical Network Representation (GRPHREP) model which is being conducted on the Los Alamos National Laboratory Integrated Computer Network (ICN). The GRPHREP model is a software system application based on graph theory and object-oriented programming methodologies. It codified the Department of Energy (DOE) Order 5637.1, which is concerned with classified computer secret policy, restrictions, and requirements. The Los Alamos ICN is required to control access to and support large-scale scientific and administrative computing. Thus, large-scale scientific and administrative computing. Thus we felt that this large, complex, and dynamic network would provide a good test for the graphical and functional capabilities of the model. Furthermore, the ICN is composed of multiple partitions that reflect the sensitivity and classification of the computation (data) and designate the required clearance level for the user

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.

Towards More Case Study Research in Entrepreneurship  

Directory of Open Access Journals (Sweden)

Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

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.

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.

Dez anos de experiência com cirurgia micrográfica pelo método de Munique: relato de 93 casos operados / A ten-year experience with the Munich method of micrographic surgery: a report of 93 operated cases  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese FUNDAMENTOS: A cirurgia de Mohs é um dos métodos mais eficazes de tratamento dos carcinomas basocelulares. A expansão de seus conceitos possibilitou o surgimento de outros métodos de checagem de margens cirúrgicas igualmente eficazes. O método de Munique é um exemplo disso. OBJETIVOS: Avaliar a efic [...] ácia da cirurgia micrográfica pelo método de Munique em um estudo de coorte com 10 anos de duração. MÉTODOS: 93 pacientes com 96 tumores cutâneos foram tratados com cirurgia micrográfica pelo método de Munique, participando de um protocolo de acompanhamento, no período de maio de 1994 a julho de 2004. RESULTADOS: 61,4% dos tumores eram recidivados; 42,3% eram recidivados mais de uma vez; 53% eram do tipo esclerodermiforme. A média do maior diâmetro dos tumores foi de 1,58cm e do menor 1,10cm. Em 95% dos casos se obteve a extirpação total do tumor, com até três estágios. A localização mais comum foi a nasal (46,3%), seguida da periocular (18,9%) e da frontal (11,5%). Perdeu-se o contato apenas com dois pacientes. Dos 96 tumores operados, apenas 11 têm tempo de seguimento inferior a dois anos. 56 pacientes foram seguidos por pelo menos cinco anos, e 45 (47,3%), por mais de seis anos. Apenas um caso de recidiva foi verificado, tendo ocorrido no sexto ano de observação. CONCLUSÃO: O método de Munique é um método eficiente de cirurgia micrográfica, tanto quanto o método de Mohs. 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. 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".

Introduction: personality psychology and the case study.  

Science.gov (United States)

This article introduces the Journal of Personality's special issue on the life voyage of Dodge Morgan who, in 1986 at the age of 54, sailed solo around the world in 150 days. Before the voyage, Morgan agreed to participate in an intensive psychological case study, the data for which provide the focus for this special issue. William Nasby and Nancy W. Read have organized the vast array of psychological data obtained from Morgan and produced a complex and illuminating interpretation of his life, drawing liberally from the five-factor trait model of personality and the life-story model of adult identity. This introduction provides a historical and intellectual context for Nasby and Read's study by considering the various ways in which personality psychologists have employed the case study in research and examining the many conceptual and methodological problems and possibilities that arise in the psychological study of the single case.

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

Directory of Open Access Journals (Sweden)

Full Text Available Trans-cutaneous electrical nerve stimulation (TENS is a treatment against pain that uses the application of an electric current. Some studies suggest that TENS would reduce the pain associated with certain types of cancer and this treatment is regularly used in therapy in contexts of interdisciplinary practice specializing in palliative oncology. However, the use of TENS in cancer cases is a matter of controversy, and its application is contraindicated by Canadian standards governing the practice of physiotherapy. This article aims to present, through a case study, some principles to guide decision making regarding the choice of this therapy in cases of cancer. Scientific evidence, standards of practice and ethical principles that should guide the choice of therapy are discussed. The use of TENS therapy in palliative care is a paradigmatic example of a common situation: the weighing by health care professionals of the benefits and potential costs, such as potential adverse effects of treatment. In the case of TENS, the benefits are associated with the reduction of pain, while a potential adverse effect would increase tumour proliferation. This difficult calculation has implications for the various stakeholders such as patients and health professionals.

Stereochemistry of compounds with coordination number ten.  

Science.gov (United States)

The stereochemistry of ten-coordinate rare-earth and transition-metal compounds is studied from the point of view of continuous shape measures (CShM) and derived tools. A total of 19 ideal ten-vertex polyhedra belonging to 12 different symmetry point groups have been considered, from which nine are retained for the description of the stereochemistries of all studied compounds. The structures of the coordination spheres are analyzed by families, according to the denticity and topology of the ligands. Some ligand topologies are seen to consistently favor usually neglected ideal polyhedra, such as the capped trigonal cupola. PMID:19551784

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.

Analysis of the Case Studies Video Recordings  

Directory of Open Access Journals (Sweden)

Full Text Available Case study method of didactic situations is a modern procedure of effective development of professional abilities in future teachers. I have been using the method for many years in future teachers training in the field of preparation of subject methodologies. A case study does not develop only the subject and didactic competences of future teachers. The self-evaluation and self-reflection processes in students also play an important role. For this purpose the third – analytical – phase of the study is carried out. Two basic methods are used for a complex analysis – macro-analytic and micro- analytic. The macro-analytic method is used to examine the course and the results of the case study: suitability of the used methods, forms and tools; using communicative tools, creating proper climate etc. The micro-analytic method is used to find out changes in students personalities and causes of the outer demonstrations of the case study. One of the examined phenomena is e.g. flexibility and creativity in adjusting the pre-concept to the course of the realization phase of the study.

Clinicopathological study of 10 cases of post-irradiation sarcoma  

International Nuclear Information System (INIS)

Ten cases of post-irradiation sarcoma (3 in the bone and 7 in the soft tissue) are presented. Underlying diseases were malignant tumors in all cases. Irradiation doses were 5,000 rad or more. The latent period ranged from 7 years and 10 months to 17 years and 3 months. Post-irradiation sarcoma consisted of osteosarcoma in two cases, malignant fibrous histocytoma (MFH) of bone in one case, soft tissue MFH in five cases, ectosteal osteosarcoma in one case and suspected leiomyosarcoma in one case. Radical treatment is desirable for this disease. However, it might be impossible because diagnosis is often delayed as a result of chronic changes of the irradiated field. Even though the risk of post-irradiation sarcoma is considered, the use of radiotherapy can not be omitted when surgery alone is not sufficient for the treatment of malignant tumors. (Namekawa, K.)

ISOE: Ten years of experience  

International Nuclear Information System (INIS)

The Information System on Occupational Exposure (ISOE), sponsored by the OECD Nuclear Energy Agency and the IAEA, was created in 1992 to facilitate information exchange between radiation protection experts from both operating organizations and national regulatory authorities and to enhance international co-operation on worker protection at nuclear power plants. The ISOE programme offers the world's largest database on occupational radiation exposure due to nuclear power plants covering, in 2001, 93% of the commercial power reactors in the world. In addition to providing the basis for analyses of dose trends, benchmarking and detailed studies, the ISOE also offers a system for rapid communication of radiation protection information and a forum for discussing occupational radiation exposure management issues through ISOE workshops and symposiums, organized annually. This paper is based on a report, published in 2002, summarizing the experience gained from ten years' of developing the ISOE and containing comments from participants on their experience with the system. Growing use of improved work management procedures, developed and published through the ISOE, has contributed to the downward trend in the annual average collective dose per reactor. The impact of a steam generator replacement on the evolution of this dose has also been demonstrated. To maintain or even further reduce the already low levels of occupational exposure, the ISOE needs to be regularly used and further promoted by its participants. In future, the ISOE can also play an important role in the decommissioning and dismantling of nuclear power plants. (author)

Usou-se [...] como instrumento um questionário semiestruturado, anônimo, aplicado em dez escolas, sorteadas dentre todas da cidade de Maceió (Alagoas), pesquisando-se adolescentes dos 12 aos 19 anos, do sexo feminino. Os dados foram analisados pelo Programa Epi Info, usando-se odds ratio e risco relativo para verificar associação entre variáveis e intervalo de confiança a 95%. Em uma amostra de 2.592 jovens, 559 (21,6%) tinham vida sexual ativa, 182 (7,0%) referiram ter engravidado e 149 (26,7%) abortado. Medo da reação dos pais, idade, falta de apoio do companheiro e rejeição da gravidez foram razões para provocar o aborto, sendo medo a mais citada, em ambos os tipos de escola. O aborto foi mais citado nas escolas públicas, sendo significativo e protetor o risco para abortar antes dos 15 anos, e significativa a relação entre abortar e estudar em escolas públicas.

At a sample of 2,592 adolescents, 559 (21.6%) had an active sexual life, 182 (7.0%) informed to have been pregnant and 149 (26.7%) to have aborted. The fear of the parents' reaction, age, lack of support of the partner and pregnancy rejection were the explanation to stimulate abortion. Fear was the most mentioned cause in both types of school. Abortion was more mentioned in public schools, being significant and protective the risk of aborting before the age of 15. The fear of the parents' reaction as a frequent cause suggests the necessity for additional studies on sexuality and communication between parents and children.

Acoustical case studies of three green buildings  

Science.gov (United States)

Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

Clinically diagnosed childhood asthma and follow-up of symptoms in a Swedish case control study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Childhood asthma has risen dramatically not only in the western societies and now forms a major and still increasing public health problem. The aims of this study were to follow up at the age of ten the patterns of asthma symptoms and associations among children with a clinically diagnosed asthma in a sizeable urban-rural community and to in compare them with demographic controls using a standardised questionnaire. Methods In a defined region in Sweden with a population of about 150 000 inhabitants, all children (n = 2 104 born in 1990 were recorded. At the age of seven all primary care and hospital records of the 1 752 children still living in the community were examined, and a group of children (n = 191 was defined with a well-documented and medically confirmed asthma diagnosis. At the age of ten, 86 % of these cases (n = 158 and controls (n = 171 completed an ISAAC questionnaire concerning asthma history, symptoms and related conditions. Results Different types of asthma symptoms were highly and significantly over-represented in the cases. Reported asthma heredity was significantly higher among the cases. No significant difference in reported allergic rhinitis or eczema as a child was found between cases and controls. No significant difference concerning social factors or environmental exposure was found between case and controls. Among the control group 4.7 % of the parents reported that their child actually had asthma. These are likely to be new asthma cases between the age of seven and ten and give an estimated asthma prevalence rate at the age of ten of 15.1 % in the studied cohort. Conclusion A combination of medical verified asthma diagnosis through medical records and the use of self-reported symptom through the ISAAC questionnaire seem to be valid and reliable measures to follow-up childhood asthma in the local community. The asthma prevalence at the age of ten in the studied birth cohort is considerably higher than previous reports for Sweden. Both the high prevalence figure and allowing the three-year lag phase for further settling of events in the community point at the complementary roles of both hospital and primary care in the comprehensive coverage and control of childhood asthma in the community.

Chloride Channel Myotonia: Study of Five Cases  

Directory of Open Access Journals (Sweden)

Full Text Available Chloride channel Myotonia is a form of channelopathy, and Myotonia is its manifestation. Myotonia may be defined as delayed relaxation of skeletal muscle after its contraction. Decreased chloride conductance across the transverse tubular system, renders the muscle membrane hyper-excitable and leads to repetitive firing, creating Myotonia. Myotonia congenital is another name for chloride channel Myotonia. Myotonia congenital appears in autosomal dominant type called Thomson disease, autosomal recessive type called Becker disease, and a type with sporadic occurrence. Symptoms appear in the first or second decade of life. Repeated muscle contraction, the so called warm up, result in resolution of the Myotonia stiffness. Muscle stiffness and hypertrophy is another finding at physical examination. In this study we report on 5 patients, which had clinical and electrical signs of Myotonia. Muscle hypertrophy and warm up phenomena were present in all cases. CPK measurement of all cases were normal. 2 patients underwent muscle biopsy that showed only atrophy and increased central nuclei. In three cases autosomal recessive inheritance (Becker, in one case autosomal dominant inheritance (Thomsen and in one case sporadic occurrence was suggested. With respect to successful results of carbamazepine therapy in 4 patients, and being excellent in one of them, we suggest carbamazepine for the first choice of Myotonia treatment.

An Industrial Case Study for Scrum Adoption  

Directory of Open Access Journals (Sweden)

Full Text Available Agile software development methods and techniqueshave been demonstrated to improve employee morale, enhanceend-product quality, and achieve customer satisfaction. Agileadoption always comes with special challenges and thus fundamental organizational changes are necessary for successful outcome. In this paper we present an in-depth case study for adopting Scrum in a multi-team and multi-project situation to a government entity in the United Arab Emirates (U.A.E. While there are many successful stories for adopting Scrum in large and small organizations, there is little known about adoption stories in a multi-project/multi-team environments. In this paper we present a case study for an unsuccessful adoption of Scrum in a government entity in the U.A.E. The government entity under study have used the traditional waterfall approach for many years and decided to move to Agile software development method.This study highlights the challenges faced during the adoptionof Scrum method with recommendations to address them. Eachorganization has its unique properties and one case study is not enough to draw conclusions for the U.A.E environment. However, the results obtained from this paper help software engineers to better understand the development environment and context factors for software projects in the U.A.E and many lessons may be learned for future Agile adoption.

A case study of chronic headaches.  

Science.gov (United States)

The following paper is a case study of a patient with a history of chronic headaches (originally diagnosed as migraine without aura) who was being treaded at the Macquarie University Chiropractic Outpatients Clinic for cervical spine dysfunction. The treatments successfully reduced the upper neck and thoracic pain that the patient was experiencing and for which they had initially presented at the clinic. During the treatments, the patient also showed a significant subjective reduction in prevalence and intensity of headaches over a four month period. Analysis of the outcome is complicated by the fact that it is not clear whether the patient's headaches were initially misdiagnosed as common migraine when in fact, they were cervicogenic. There may be some overlap between the two conditions, and a possible causative relationship between cervical spine dysfunction and common migraine. Furthermore, this case study discusses the validity of chiropractic treatment of organic disorders such as chronic headache or migraine. PMID:17987139

Marketing and clinical trials: a case study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

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.

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

Scientific Electronic Library Online (English)

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish 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, longitud [...] inal 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. Abstract in english 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.

The case study of biomaterials and biominerals  

Science.gov (United States)

The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

LandIT Database : A Case Study  

DEFF Research Database (Denmark)

Many of today’s farming systems are composed of purpose-built computerized farming devices such as spraying equipments, harvesters, fertilizer spreaders and so on. These devices produce large amounts of data. In most of the cases, it is essential to store data for longer time periods for analysis and reporting purposes. This paper presents the LandIT database; which is result of the LandIT project, which refers to an industrial collaboration project that developed technologies for communication and data integration between farming devices and systems. The LandIT database in principal is based on the ISOBUS standard; however the standard is extended with additional requirements, such as gradual data aggregation and flexible exchange of farming data. This paper describes the conceptual and logical schemas of the proposed database based on a real-life farming case study.

Devising and performing a scientific experiment is an art, and it is common to hear scientists talk about the 'beauty' of an experiment. What does this mean in chemistry, the experimental science par excellence? And what are the most beautiful chemical experiments of all time? This book offers ten suggestions for where beauty might reside in experimental chemistry. In some cases the beauty lies in the clarity of conception; sometimes it is a feature of the instrumental design. But for chemistry, there can also be a unique beauty in the way atoms are put together to make new molecules, substanc

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 deterom 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

Simulated Ten Pin Bowling Collisions  

Science.gov (United States)

This work investigates the results of the dynamics in the collisions that occur in ten pin bowling. A finite element modeling system (LS-Dyna) was used to construct simplified but approximately physically realistic models and simulate collisions involving the twelve body system composed of a ball, ten pins, and a floor. The investigation focuses on the qualitative features of the map of final pin configuration as a function of the initial conditions. To appropriately limit the breadth of the initial configuration space investigated, the only variables adjusted were the position of the ball upon entering the pins and the initial angle of velocity relative to the long axis of the lane. Results concerning the size and shape of the sets of initial conditions that lead to similar final configurations, in particular those leading to none of the pins remaining standing (aka "strikes"), are shown.

Environmental qualification - facilities and case studies  

International Nuclear Information System (INIS)

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, upgrading 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 comp 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.

Randomized recruitment in case-control studies.  

Science.gov (United States)

A new sampling approach for case-control studies offers a flexible alternative to frequency matching. In the "randomized recruitment" method, subjects are individually randomized to be recruited or not on the basis of investigator-imposed recruitment probabilities that can depend on both disease status and values of covariates already available or ascertained in a screening interview. When there is prior information about the odds ratios associated with the screening variables, such a design can achieve "probability matching," without the well-known disadvantages that encumber traditional matching. The method can also be used to enlarge the relative size of subsamples of interest. Following randomized recruitment, a modified logistic regression analysis allows unbiased estimation of effects associated with all variables studied, including the "matching" variables. One can also readily fit an additive model. The method is illustrated by developing the recruitment probabilities required for probability matching on age, sex, and cigarette smoking status in an ongoing study of lung cancer and exposure to radon progeny in which smoking cases are undersampled.

Reinforcement learning: Solving two case studies  

Science.gov (United States)

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.

A Codesign Case Study in Computer Graphics  

DEFF Research Database (Denmark)

The paper describes a codesign case study where a computer graphics application is examined with the intention to speed up its execution. The application is specified as a C program, and is characterized by the lack of a simple compute-intensive kernel. The hardware/software partitioning is based on information obtained from software profiling and the resulting design is validated through cosimulation. A locally developed interface model, Merlin, is used as the basis for co-simulation. The achieved speed-up is estimated based on an analysis of profile information.

Functional retrograde amnesia: a quantitative case study.  

Science.gov (United States)

The memory impairment of a patient suffering from functional retrograde amnesia was assessed both during the amnesic episode and after its termination. The patient's performance on a task tapping semantic memory was nearly identical on the two test occasions, but his performance on a task tapping episodic memory substantially changed across test sessions. Cueing procedures revealed that in spite of the patient's restricted access to episodic memory during the amnesic period, a relatively intact "island" of episodic memories could be uncovered. The distinction between episodic and semantic memory, as well as the relation between organic and functional retrograde amnesia, are discussed in light of the case study. PMID:7145078
