year-old danish men: Topics by WorldWideScience.org

[Pelvic dimensions in 10-14 year-old girls].

A population of male civil servants in Rome, Italy, was investigated to determine the prevalence of symptomatic and asymptomatic gallstone disease. Field activities started in December, 1982 and were concluded in July, 1984. Diagnosis was made using real-time ultrasonography. Participation in the study was 71.5%. Prevalence of gallstone disease was 8.2% and increased with age from 2.3% in the 20- to 25-year-old age group to 14.4% in the 60- to 69-year-old age group, based on both presence of gallstones and history of cholecystectomy. About one-third of the subjects with gallstone disease had previously been submitted to cholecystectomy. Only 7.7% of the subjects with presence of gallstones complained of at least one episode of biliary pain in the preceding 5 years. Frequency of "minor" dyspeptic symptoms was not different between men with and those without gallstones. PMID:3391519

Aims To study the effect of fish consumption on the risk of acute coronary syndrome (ACS) in healthy subjects. Methods and results This Danish follow-up study included 57 053 men and women between 50 and 64 years. Intake of lean and fatty fish was estimated from a detailed and validated food frequency questionnaire. Potential cases of ACS were identified through nationwide medical databases. A total of 1122 cases of ACS were verified during a mean follow-up period of 7.6 years. Among men, intake of fatty fish was associated with a lower risk of ACS. For men in the highest quintile of fish intake compared with the lowest quintile, the hazard ratio was 0.67 (95% confidence interval: 0.53-0.85). The inverse association was observed for intakes >6 g of fatty fish per day with no obvious additi...

Should Male Gender Assignment be Considered in the Markedly Virilized Patient With 46,XX and Congenital Adrenal Hyperplasia?

British Library Electronic Table of Contents (United Kingdom)

Purpose We assess the outcome in 46,XX men with congenital adrenal hyperplasia who were born with Prader 4 or 5 genitalia and assigned male gender at birth. Materials and Methods After receiving institutional review board approval and subject consent we reviewed the medical records of 12 men 35 to 69 years old with 46,XX congenital adrenal hyperplasia, of whom 6 completed social and gender issue questionnaires. Results All subjects were assigned male gender at birth, were diagnosed with virilizing congenital adrenal hyperplasia at age greater than 3 years and indicated a male gender identity with sexual orientation to females. Ten of the 12 subjects had always lived as male and 2 who were reassigned to female gender in childhood subsequently self-reassigned as male. Nine of the 12 men had ...

The establishment of the Danish windmill industry - was it worthwhile?

The establishment of the Danish windmill industry - was it worthwhile?

The renewed interest for using wind energy commercially is not more than twenty-five years old. From an experimental stage of turning wind energy into electricity in the 1970s, a new industry for producing standardised windmills gained foothold in the beginning of the 1980s and since then it has developed rapidly through the 1980s and the 1990s. The Danish innovators of the new windmill technology have been the pioneers behind this development, and Denmark has succeeded in acquiring a first mover advantage on the world market. This position has been maintained and at present Denmark satisfies more than half of the world market's demand for windmills. There are at least two reasons for this pioneering position of the Danish windmill industry. First, Denmark is by nature very `abundant' in wind energy due to its geographical position at the nexus between the Gulf Stream and the European ...

Thin-Section CT findings of lung small peripheral adenocarcinoma detected by CT physical examination

Americans' political participation in the 1993-94 national health care reform debate.

Subjects were 18 cases with adenocarcinoma of 20 mm or less in diameter, which were detected and resected surgically from September, 1993 to August, 1998. On these cases, thin-Section CT (TSCT) images were compared with pathological findings. Patients were 15 men and 3 women, with mean age of 63.4-year-old. An average tumor size was 11.5 mm (5-17 mm). According to pathological classification of Noguchi, type A as in 6 cases, type B in 3, type C in 7 and type F in 2. TSCT was carried by vas voltage =150 kVp, vas current =200 mA, beam width =2 mm, WW =2000 HU, and WL =-700 HU. The ratio of CT attenuation value in cancer by TSCT correlated with the ratio of aeration rate in the pathologic specimen. The cases of 30% or less on the ratio of CT attenuation value were 100% in types A and B, and 71% in type C. These results suggested that it is necessary to devide into two type in group of type C and the ratio of CT attenuation value is important on ...

PAGETOID RETICULOSIS IN A 5 YEAR OLD BOY

The health politics and policy communities are still struggling with the question of "what went wrong" in the 1993-94 health care reform effort. Here I identify which Americans were politically active and inactive during the health care reform debate to explore the role political participation may have had in determining the outcome of the debate. Using data from a national and California random-sample telephone surveys, and controlling for other demographic attributes, I found that those who engaged in political activity specifically related to health care reform were disproportionately more likely to be self-identified conservatives, less likely to favor an employer mandate plan, more likely to be fifty to sixty-four years old, more likely to be men, and more likely to have greater interest in and knowledge of the health care issue. Even in California, where a single-payer proposal was on the November ballot, ...

Uncommon mucosal metastases to the stomach

Since the 1970s, Danish electricity supply has been dependent on imported coal. This has lead to greater reliability of supply, as could be seen during the Gulf War when Danish electricity prices remained stable in contrast to conditions in other countries. The disadvantage is the air pollution caused by coal combustion. This is regulated, it is stated, by several international laws and agreements, and these are named here. The nature of this form of pollution is explained in relation to actual Danish power plants and their efforts to reduce emissions of sulphur dioxide and nitrogen oxides. Carbon dioxide, which is a greenhouse gas, is also emitted. Danish environmental policy concentrates on these problems. The efforts of the electric power companies to reduce air pollution are detailed, both nationally and internationally, and their positive consequences are described. Desulphurization and ...

The stomach may be involved by hematogenous spread from a distant primary (most commonly breast, melanoma or lung), or by contiguous spread from an adjacent malignancy, such as the pancreas, esophagus and gallbladder. These latter sites may also involve the stomach via lymphatic or haematogenous spread. We present three cases of secondary gastric malignancy.Methods/ResultsThe first is a 19-year-old male who received a diagnosis of testicular choriocarcinoma in September 2004. Metastatic malignancy was demonstrated in the stomach after partial gastrectomy was performed to control gastric hemorrhage.The second is a 75-year-old male, generally well, who was diagnosed with adenocarcinoma of the lung in September 2005. Poorly differentiated adenocarcinoma of the lung was demonstrated in a subsequent ...

Solar cells in architecture; Solceller i arkitekturen

The temperature elevations in anatomically based human phantoms of an adult and a 3-year-old child were calculated for radio-frequency whole-body exposure. Thermoregulation in children, however, has not yet been clarified. In the present study, we developed a computational thermal model of a child that is reasonable for simulating body-core temperature elevation. Comparison of measured and simulated temperatures revealed thermoregulation in children to be similar to that of adults. Based on this finding, we calculated the body-core temperature elevation in a 3-year-old child and an adult for plane-wave exposure at the basic restriction in the international guidelines. The body-core temperature elevation in the 3-year-old child phantom was 0.03 deg. C at a whole-body-averaged specific absorption rate of 0.08 W kg{sup -1}, which was 35% smaller than in the adult female. This difference is attributed to the child's ...

Water consumption of a six-year-old river red gum plantation in the Southern Zagros Mountains, Iran

This book contains the results of an architectural evaluation of building examples with integrated photovoltaic. Danish Building and Urban Research and Danish Technological Institute conducted the work within the framework of Solar Energy Centre Denmark. Seven examples are selected to inspire Danish architects and building owners to use PV in the building environment. The examples come from Denmark and countries (the Netherlands and Germany) with similar building traditions, climate and solar conditions. All the examples demonstrate architectural concepts that integrate photovoltaic as a natural part of the building envelope. (BA)

Water is the most important limiting factor in the development of arid environments; therefore, optimization of water use is a necessity in desert reclamation projects. Evapotranspiration of a 6-year-old river red gum (Eucalyptus camaldulensis Dehnh.) plantation, located in a sedimentation basin of an artificial recharge of the Gareh Bygone Plain groundwater system in Iran?s southern Zagros Mountains, was studied during a 7-month period. A neutron moisture probe was used to monitor soil water changes in the root zone. Soil water depletion following rapid drainage for blocks receiving relatively high, medium and low volumes of floodwater were 809.6, 312.4, and 203.1 mm, respectively, for a 150-day period. Soil water potential during most of the study period was below ?1.5 MPa. This study pr...

Human brain development in infants with PET and FDG

Fluoride rinsing and dental health inequalities in 11-year-old children: an evaluation of a supervised school-based fluoride rinsing programme in Edinburgh

The authors used studies of local cerebral metabolic rate for glucose (LCMRGlc) to examine development of cerebral organization in 5 days to 1 year old children. A group (n=8) of infants with diverse pediatric disorders allowed investigation of developmental changes in LCMRGlc, while also providing relevant clinical management information. Patients consisted of questionable and definite neonatal seizures, cerebral embolism from cardiac sources, and otherwise normal infants with facial nevi with consideration of Sturge-Weber. Gradual increase in cortical LCMRGlc coincides with suppression of intrinsic subcortical reflexes present in all newborns. Two retarded children (2 years old) showed LCMRGlc developmental patterns of a few days old, which corresponded to their functional and mental status. These studies illustrate great potential of PET to study normal and altered states of human brain development.

A multifactorial strategy of pain management is associated with less pain in scheduled vaccination of children. A study realized by family practitioners in 239 children aged 4-12 years old

British Library Electronic Table of Contents (United Kingdom)

Background and aims. The multiplicity of vaccine injections during childhood leads to iterative painful and stressful experiences which may lead in turn to anticipated pain and then possibly to a true needle phobia. We aimed at evaluating a multifactorial strategy of pain management combining pharmacological and non-pharmacological approaches during vaccination, as compared to usual care, in 4- to 12-year-old children. Methods. In all, 239 children were enroled by 25 family practitioners in an open-label study. After a pseudo-randomization, usual pain management (n = 132) was compared to a multifactorial strategy (n = 107) associating preliminary application of an anesthesic patch, preferential use of specified vaccines, child education by the parents and the doctor, parental accompaniment...

Transesophageal echo to help percutaneous closure of ventricular septal defect post acute myocardial infarction

A new prototype model system named AirGIS has been developed to support local authorities in air quality management for big Danish cities. The system is based on the Danish operational street pollution model (OSPM), technical and cadastral digital maps and Danish national administrative databases on buildings, cadastres and populations. It applies a geographic information system (GIS). AirGIS estimates ambient air pollution levels at high temporal and spatial resolutions. The model system enables mapping of traffic emissions, air quality levels and human exposures at residence addresses, at workplace addresses and in streets. Mapping and scenario results can be compared with air quality limits. Impact assessment of traffic air pollution abatement measures can also be carried out. (author)

This study investigated how men and women perceive online and offline sexual and emotional infidelity. Undergraduates from a large university in Northern Ireland participated in the study. It was found that men, when forced to decide, were more upset by sexual infidelity and women by emotional infidelity. It was also found that men were more likely to believe that women have sex when in love and that women believe that men have sex even when they are not in love. It was not, however, found that either men or women believed that having cybersex implied the other was also in love or that being in love online implied they were having cybersex. These results are explained through a social-cognitive lens.

Solid-pseudopapillary tumor of the pancreas in a 13-year-old girl - case report

Radiation exposure of children in pediatric radiology. Pt. 6. Conversion factors for reconstruction of organ dose in abdominal radiography; Zur Strahlenexposition von Kindern in der paediatrischen Radiologie. T. 6. Konversionsfaktoren zur Rekonstruktion von Organdosen bei Abdomenaufnahmen

The solid-pseudopapillary tumor (SPT) of the pancreas is a rare type of exocrine pancreatic neoplasm. SPT predominantly affects young women and female children, and is usually discovered incidentally. This tumor is generally benign with a low incidence of malignancy. A 13-year-old girl was admitted to the hospital with a few weeks' history of mild abdominal pain and jaundice. On physical examination, there was no palpable mass. The laboratory tests showed increased SR, CRP, high bilirubin, amylase and lipase serum levels. Ultrasound imaging revealed a solid lesion in the region of the pancreatic head. On MRI, precise tumor localization in the head of the pancreas with pancreatic duct dilatation and compression of the common bile duct were visualized. Pancreaticoduodenectomy and cholecystectomy was performed with good clinical outcome. Microscopic and immunohistochemical studies indicated that tumor cells were typical of SPT without any signs of malignancy. After ...

Ontogeny of accidental wetlands and hydric soil development in surface mined landscapes

A population of female civil servants in Rome, Italy, was investigated to determine the prevalence of symptomatic and asymptomatic gallstone disease and to define the associated factors. Field activities started in February 1981 and concluded in April 1982. Diagnosis was assessed by real time ultrasonography. Prevalence of gallstone disease increased with age from 2.5% in the 20- to 29-year-old age group to 25.0% in the 60- to 64-year-old age group, based on both presence of gallstones and history of cholecystectomy. Only one third of the women with gallstones had complained of at least one episode of biliary pain in the last five years. Frequency of "minor" dyspeptic symptoms was not different between women with and those without gallstones. In a multiple logistic function analysis, a positive association was found between age, body mass index, parity, and prevalence of gallstone disease. No association was demonstrated between the presence of ...

Evaluation of femoral head perfusion by dynamic MRI

Reducing conditions are periodically present in hydric soils and are essential for chemical processes that support wetland functions and values. Indicators of these conditions, i.e., redoximorphic features, can be useful in determining the presence of a hydric soil. However, young wetlands, i.e., those recently formed, may not possess reducing conditions and/or may not exhibit redoximorphic features. Few studies have addressed the time needed for hydric soil development. In this study, we present data on redoximorphic features, including chroma and oxidized rhizospheres, gathered from two sets of wetlands in southwestern Virginia, including (1) constructed wetlands that are 3 years old and (2) accidental wetlands that are 10 to 30 years old. Under conditions described for these sites, there is strong evidence that discernable redoximorphic features form in accidental wetlands within 10 years, but not ...

Effective radiation therapy on two cases of primary Ewing's sarcoma of the rib

The purpose of this study was to evaluate the usefulness of dynamic MRI for femoral head perfusion. Objects were 64 femoral heads of 44 normal cases (20-95 years old), 10 cases (33-90 y) of femoral neck fracture and 8 cases (61-86 y) using steroid due to articular rheumatism, nephrosis and other diseases. Siemens 1.0 T Magneton Impact with body array coil was used for dynamic MRI by the fast low-angle shot 2D method for every 17 sec interval. Gd-DTPA was injected intravenously. ROI was defined in the center of femur head and of trochanter to monitor their values for the dynamic curve. Evaluation was done on the ratio of enhancement ratio (ER) in the head/trochanter and on the curve in both heads. In normal cases, the head ER was significantly lower in >60 years old cases. There was neither significant correlation between their head/trochanter ER ratios nor significant difference between their dynamic ...

'Hair-on-end' skull changes resembling thalassemia caused by marrow expansion in uncorrected complex cyanotic heart disease

Two cases of primary Ewing's sarcoma of the rib are reported, in which radiation therapy was quite effective. Case 1 was an 18-year-old female who had had an operation and radiation therapy for Ewing's sarcoma of the left 7th rib. She was referred to our hospital after a recurrent tumor was found. Radiation therapy (tumor dose 46.2 Gy) and chemotherapy were given. The tumor disappeared and there has been no relapse for 1 year and 3 months after the treatment. Case 2 was a 2-year-old-infant. Radiation therapy (tumor dose 74 Gy) was given for primary Ewing's sarcoma of the left 6th rib. The tumor became small and was successfully removed at operation. There has been no relapse or distant metastasis for 8 months following the operation. We emphasize the importance of multidisciplinary treatment in case 1 and the usefulness of preoperative radiotherapy in case 2. (author).

Towards the solid-state rechargeable battery

''Hair-on-end'' skull changes resembling thalassemia were rarely described in the 1950s and 1960s in children with cyanotic congenital heart diseases; these changes were described almost entirely in patients with tetralogy of Fallot or D-transposition of the great arteries. As these lesions have become correctable, the osseous changes, never common, seem now only to exist in a small number of patients with uncorrectable complex cyanotic congenital heart disease who survive in a chronic hypoxic state. We present two cases: a case of marked marrow expansion in the skull of a 5-year-old boy with uncorrectable cyanotic heart disease studied by CT, and a second case of an 8-year-old with tetralogy of Fallot and pulmonary atresia studied by plain skull radiographs. The true incidence of these findings is unknown. (orig.)

A 67-year-old man presented with gastrointestinal bleeding resulting from a fistula between the aortic stump and the fourth part of the duodenum 14 months after an axillobifemoral bypass, graft excision, and aortic stump closure for aortic graft infection. The patient initially refused any attempt at definitive surgical treatment so coil embolization of the aortic stump was performed via a brachial approach. Coil embolization may be a useful adjunct in the management of such difficult problems. This approach may buy time and allow careful planning of a definitive treatment or may serve as a palliative procedure in inoperable patients. PMID:15947052

Stress fracture of the clavicle associated with sternocostoclavicular hyperostosis

The aortovenous fistulas are rare, most of them are aortocaval fistula. The non-caval communication of the fistula is sparse. Herein we report a 47-year-old female diagnosed as traumatic aorto-superior mesenteric vein (Ao-SMV) fistula. The abdominal pain, fullness, and frank bruit on abdominal auscultation suggested the diagnosis of an intra-abdominal arteriovenous fistula. The diagnosis of Ao-SMV was further confirmed by the computed tomography (CT) and aortography. The fistula was successfully treated with transcatheter coil embolization. This is the first case of Ao-SMV fistula. It provides an alternative option of treatment other than conventional surgery. PMID:19327940

On radiography, hyperostosis of the anterior chest wall and ankylosis of the sternoclavicular joint were evident in addition to the fracture. Fracture healing was uneventful after 2.5 months. Ankylosis of the sternoclavicular joint may have caused increased stress at the midshaft of the clavicle by daily activity or minor trauma. Such a fracture is a rare complication of sternocostoclavicular hyperostosis. (orig.)

The follow-up of a radionuclide bone study, however, enabled the dignosis of a refracture. From these findings, it is further evident that the decreased bone metabolism in older patients has to be considered. Thus, although the initial bone scan following the trauma is negative, a follow-up scan should be performed within a 4 day-period.

She underwent chemotherapy with no symptomatic improvement. Post-chemotherapy computed tomographic scan of the chest showed no appreciable reduction in tumor size. Surgical excision was carried out with excellent results.

Past, present and future of elementary particle physics

On-line partial discharge measurements and off-line dielectric spectroscopy measurements of six 115 kV XLPE cable systems

The 'elementary' particle physics began in 1935, when Hideki Yukawa published his pioneering pi-meson theory, and the problem of strong interaction was finally solved 40 years later by the establishment of the Standard Model. The composite models of hadrons by the Sakata school and Sin-itiro Tomonaga's renormalization theory for quantum electrodynamics played essential roles for finding this beautiful solution. It is really surprising that it took only 40 years to solve such desperately difficult problem. The 'elementary' particle physics then split into two new fields, quark-hadron physics' and 'unified (ultimate) theory of particle physics', which are now 30 years old already. (author)

Nasal cavity volume measured in normal persons by MRI

This paper reported on a study in which partial discharge (PD) measurements were performed on 6 underground transmission cable circuits to determine the effectiveness of PD measurements on fluid fill cables. The cables were between 37 and 56 years old. PD activity was detected from the terminations of H11L and H3L Cable 2. However, for cables from H3L Basin TS to Mill Street junction, PD activity was detected originating from within the main cable insulation.

Nasal cavity volume measured in normal persons by MRI

Nasal cavity volume was studied in 69 healthy volunteers (from 8 to 23 years old) by MRI. The right and left nasal cavity areas were measured on horizontal images displayed directly on the MRI console. The nasal cavity volume was obtained by integrated volume calculation. The nasal cavity volume was positively correlated with age, body height and weight up to age 16. The body height and weight reached a plateau at 16 years, but the nasal cavity volume continued to increase. There was no significant difference in the volumes of the right and left cavities.

Isolated laevocardia and corrected transposition of the great vessels with total situs inversus

Pulmonary embolism complicated by transcatheter arterial chemoembolization (TACE) in known to be due to the use of large amount of lipiodol as an embolic agent. To our knowledge, massive tumoral pulmonary embolism following TACE and confirmed by surgery has not been described in the literature. In this report, we detail the cas of a 49-year-old man in whom cyanosis and hypotension developed abruptly on the day of TACE.. Chest CT revealed diffuse low-attenuated lesions in both pulmonary arteries. Histopathological specimens after emergent pulmonary arterial embolectomy confirmed the presence of massive tumor emboli of hepatocellular carcinoma.

Incidental discovery of asplenia syndrome, with situs inversus and a normal heart by radionuclide biliary imaging. A case report

Isolated laevocardia combined with corrected transposition of the great arteries and complete situs inversus is rare. Due to discordant interrelationships between atria and ventricles and between ventricles and great arteries, both anomalies result in a normal circulation. In the presented case no associated cardiac malformations were present and the 55-year-old woman remained symptom-free for a long time until she developed an acquired valve disease. A systematic approach to chamber localisation in complex morphologic lesions of the heart is reviewed, and the value of CT, which can be applied successfully in older children and adults is demonstrated.

Improvement of muscle strenght independently of analgesic effect following spinal cord stimulation. A case report.

/sup 99m/Tc biliary imaging was performed on a 34-year-old woman who was being investigated for suspected cholelithiasis. A left-sided liver was detected. On subsequent radionuclide imaging, partial visceral situs inversus and asplenia were demonstrated. Extensive roentgenographic investigation, ECG, echocardiogram, and laparotomy confirmed the radionuclide findings. Asplenia syndrome may exist without cardiovascular abnormalities and thus be undiscovered. Radionuclide imaging is important in the diagnosis of this syndrome.

Idiopathic renal hematuria in a military working dog.

Spinal cord stimulation (SCS) is frequently used for relief of chronic benign pain resistant to conservative therapies. Clinical practice suggests, at least in patients with failed back surgery syndrome (FBSS), the possibility that SCS significantly improves motor performances. We present here the case of a 41-years-old female patient with FBSS, who showed a clear improvement in muscle strength after SCS, persisting at 6-months follow-up. We speculate that the electrical stimulation of posterior columns could potentiate the caudal, segmental spinal reflexes resulting in a facilitation of motoneurons activation. PMID:16175150

Diagnostic ultrasound and contrast radiography demonstrated large blood clots in the urinary bladder and a filling defect in the right renal pelvis. At surgery, clotted blood was present in the right ureter and bladder. Following right nephrectomy, the dog returned to training. One month later, elevations in urea nitrogen and creatinine were noted. Hematuria recurred at 3 months and the dog was found dead in its kennel. Necropsy showed a blood-filled left renal pelvis and ureter. PMID:1454185

Hypersersensitivity and Kounis syndrome due to a viper bite

British Library Electronic Table of Contents (United Kingdom)

A 60-year-old male was bitten by a venomous snake (Vipera ammodytes) and gradually developed signs of an allergic reaction including generalized itching, generalized rash, and chest discomfort. This was followed by severe retrosternal pain with electrocardiographic evidence of an inferior myocardial ischemia progressing to acute myocardial infarction. Cardiac enzymes and troponin, serum tryptase, and histamine were elevated. Coronary arteriography showed normal coronary arteries. This is a characteristic type I variant of Kounis syndrome, which is the concurrence of acute coronary syndromes with conditions associated with mast cell activation including allergic or hypersensitivity reactions as well as anaphylactic or anaphylactoid reactions.

Ewing's sarcoma of the humerus mimicking fibrous dysplasia on imaging and biological behavior

Diffusion-weighted MRI suggests the coexistence of cytotoxic and vasogenic oedema in a case of deep cerebral venous thrombosis

We present the case of a 12-year-old girl who presented with a pathological fracture through a benign-appearing osteolytic lesion that was presumed to represent fibrous dysplasia. The fracture healed, and over the next 2.5 years there was further refracturing and healing with progressive osteolysis. A biopsy was performed and revealed Ewing's sarcoma. The disease was locally controlled by neoadjuvant chemotherapy and radiation therapy. The patient is disease free with excellent function 6 years following the discovery of the lesion. We illustrate and discuss the sequence of events. (orig.)

Case report 437: Solitary (unicameral, simple) bone cyst of the scapula

Gallium imaging is increasingly being used for the early detection of complications in patients with AIDS. A 26-year-old homosexual man who was HIV antibody positive underwent gallium imaging for investigation of possible Pneumocystis carinii pneumonia. Widespread cutaneous focal uptake was seen, which was subsequently shown to be due to mycobacterium avium-intracellulare (MAI) septicemia. This case demonstrates the importance of whole body imaging rather than imaging target areas only, the utility of gallium imaging in aiding the early detection of clinically unsuspected disease, and shows a new pattern of gallium uptake in disseminated MAI infection.

The lesion had the appearance of a highly aggressive, cyst-like disorder that appeared to be benign. Biopsy and histological preparation confirmed the presence of a solitary bone cyst. The clinical, radiological, and pathological criteria associated with a solitary bone cyst, particularly in the scapula, were discussed and the literature was reviewed. The differential diagnosis was stressed and a number of examples of scapular lesions was presented radiologically, particularly lesions that might be confused with solitary bone cyst. (orig./SHA).

A 37-year-old military mechanic presented to our institution with a chronic history of a slowly enlarging left elbow antecubital fossa mass. There was no history of other chronic illness or trauma. Magnetic resonance imaging (MRI) and excisional biopsy revealed fatty villi and synovial inflammation within the left bicipitoradial bursa, consistent with lipoma arborescens. Four years later the patient presented with a 6-month history of swelling at the antecubital fossa of the opposite elbow. Diagnostic computed tomography and MRI examinations were performed. The surgical and pathologic findings confirmed the imaging diagnosis of lipoma arborescens at the right bicipitoradial bursa. (orig.)

Acute lymphoblastic leukemia with multiple cytogenetic abnormalities secondary to treatment of Ewing's sarcoma

Original pictures installed in the 1st and 2nd generation type central control panels (CCP) and new 'Awarable and Complex' pictures were made on personal computers and evaluated. A total 18 of actual plant operators (M=32.3, SD=10.5 years old) participated in the evaluation. The operators rated the new CRT pictures highly. The response times using the new CRT pictures were shorter than those by the original pictures. Both results suggested that the CRT picture design guidelines based on the operators' plant images were effective for improving their performance. (author)

Plain chest X-ray demonstrated paravertebral positioning of the chest-tube tip, and magnetic resonance imaging revealed hematomas in the region of the chest-tube tip and the phrenic nerve fibers. The trauma to the phrenic nerve was apparently secondary to malposition of the chest tube. This is a rare complication and has been reported mainly in neonates. Radiologists should notify the treating physicians that the correct position of a chest drain tip is at least 2 cm distant from the vertebrae. (orig.)

The Relationship between Intimate Partner Violence, Rape and HIV amongst South African Men: A Cross-Sectional Study

We encountered a case of Ewing's sarcoma. The patient was a 19 year-old girl, who visited a local physician because of pain in the left scapular region, and was referred to us. Roentgenograms of her left scapula revealed an irregular moth-eaten shadow which was suspected to be a malignant bone tumor. The histological diagnosis of Ewing's sarcoma was comfirmed by needle biopsy. The initial stage of treatment consisted of radiation therapy (6000 rads) and chemotherapy (VAC and ADR). At the end of the initial stage, the symptoms were improved, the size of the local lesion was reduced on the roentgenogram and there was no evidence of distant metastases. (author).

Validity of dementia diagnoses in the danish hospital registers

This report presents the Business Plan for the establishment of the Wind Turbine Component Centre (CWTC) to meet the objectives of performing theoretical research and experimental testing. The core idea of a CWTC is to support the Danish wind energy industry and research activities at the component level improving the competitive advantage of that industry. The CWTC will in itself operate its activities, including access to test and experimental facilities, on a semi commercial basis. The business model for the CWTC presented is based on revenues coming from component manufacturers as well as research grants, and will include membership fees as well as hourly payment and larger projects where payment is a limited project sum. The presented roadmap model clarifies the development path towards a fully developed CWTC, which will cover test of all important components along the drive-train as well as offering a comprehensive systematic understanding of the entire ...

[Neurodevelopmental follow-up of premature children in Lausanne and Geneva].

Background:The validity of dementia diagnoses in the Danish nationwide hospital registers was evaluated to determine the value of these registers in epidemiological research about dementia. Methods: Two hundred patients were randomly selected from 4,682 patients registered for the first time with a dementia diagnosis in the last 6 months of 2003. The patients' medical journals were reviewed to evaluate if they fulfilled ICD-10 and/or DSM-IV criteria for dementia and specific dementia subtypes. The patients who were still alive in 2006 were invited to an interview. Results: One hundred and ninety-seven journals were available for review and 51 patients were interviewed. A registered diagnosis of dementia was found to be correct in 169 (85.8%) cases. Regarding dementia subtypes, the degree of agreement between the registers and the results of the validating process was low with a kappa of 0.36 (95% CI 0.24-0.48). Conclusion: The validity of dementia syndrome in the ...

Vitiligo during Treatment of Crohn's Disease with Adalimumab: Adverse Effect or Co-Occurrence?

Preterm children born before 32 weeks of gestation represent 1% of the annual births in Switzerland, and are the most at risk of neurodevelopmental disabilities. A neurological surveillance is thus implemented in the neonatal units, and multidisciplinary neurodevelopmental follow-up is offered to all our preterm patients. The follow-up clinics of the University hospitals in Lausanne and Geneva follow the Swiss guidelines for follow-up. An extended history and neurological examination is taken at each appointment, and a standardized test of development is performed. These examinations, which take place between the ages of 3 months and 9 years old, allow the early identification and treatment of developmental disorders frequent in this population, such as motor, cognitive or behavioral disorders, as well as the monitoring of the quality of neonatal care.

Abstract Adalimumab is a fully human monoclonal anti-tumor necrosis factor-a agent that is approved for the treatment of Crohn's disease. It has a good safety profile, injection site reactions being the most common adverse effect. We report a case of a 54-year-old woman with a 30-year history of Crohn's disease who developed achromic patches on the trunk and upper extremities after initiating treatment with adalimumab. Cutaneous biopsy confirmed diagnosis of vitiligo and laboratory testing ruled out thyroid disease. Concomitant occurrence of vitiligo and inflammatory bowel disease, although rare, has been described. A common autoimmune basis could explain this fact. Moreover, multiple cutaneous adverse effects have been described in the literature secondary to biologic treatments, includin...

Using the Child Behavior Checklist with African American and Caucasian American Adopted Youth

Unusual extraction treatment of Class I bialveolar protrusion using microimplant anchorage.

The purpose of this study is to examine the cross-ethnic measurement equivalence of the "Child Behavior Checklist" (CBCL) for 6- to 18-year-olds (2001, parent version) using a sample of African American special needs adopted children, along with a comparison group of Caucasian American special needs adopted children. Reliability and multiple sources of postdictive criterion-related validity were analyzed, and a confirmatory factor analysis of the CBCL within and between participating groups was performed. The results indicate that for practical purposes, the CBCL items appear reliable but not valid in terms of assessing the mental health profiles of both African American and Caucasian youth. These findings are significant because they have important implications for the practical utility of the CBCL in the field for adopted youth. (Contains 6 tables.)

Treatment of asymptomatic internal resorption of a maxillary premolar tooth in a military working dog.

This case report describes the treatment of a 16-year-old girl who had severe bialveolar protrusion. Patients with bialveolar protrusion are commonly treated with four first premolar extractions and retraction of the anterior teeth. Unfortunately in this patient, the mandibular left second molar had to be extracted because of extensive caries. To create sufficient space for retraction of the anterior teeth, the mandibular left posterior teeth were retracted with the mandibular posterior microimplant (1.2 mm in diameter, 6 mm long) placed into the retromolar area followed by en masse retraction of the mandibular anterior teeth. Microimplants can provide anchorage for obtaining a good facial profile even without premolar extraction in the case of bialveolar protrusion with the absence of the second molar. PMID:17319776

Transient azotaemia is associated with a high risk of death in hospitalized patients

An asymptomatic pink discoloration of a maxillary right fourth premolar tooth was discovered during a routine oral examination on a 9 year-old Belgian Malinois dog. A radiolucent lesion was seen in the pulpal chamber on radiographic examination. The lesion had perforated the mesiobuccal root of the tooth. The primary differential diagnosis was idiopathic internal resorption. The tooth was treated by partial resection (removal of the mesiobuccal root and associated crown). A vital pulpotomy and amalgam restoration was performed on the remaining tooth structure. A follow-up 1 year later demonstrated a successful treatment outcome. The animal was asymptomatic and able to perform military duties. Clinical and radiographic signs of healing were evident and the tooth was functional. PMID:10518874

The prevalence of absence of the palmaris longus muscle in the Bahraini population

British Library Electronic Table of Contents (United Kingdom)

Abstract Absence of the palmaris longus muscle has been well documented in several populations at a prevalence rate ranging between 2.2 and 63.9% which varies according to race, sex, and side of the body. There is little documentation of the prevalence of absence of this muscle from populations in the Arabian Gulf region. We examined 1,043 subjects, 3 85 years old, from the Kingdom of Bahrain for the presence or absence of the palmaris longus muscle using the conventional test for the presence of this muscle. Statistical analyses investigated the association of muscle absence with sex, hand dominance, and laterality. The palmaris longus muscle was absent in 36.8% of subjects. Bilateral absence (19%) was more common than unilateral absence (17.9%) with preponderance in female subjects. The ...

The chance finding of an aneurysm of the right sinus of Valsalva in an 11-year-old child with a ventricular septal defect and a pericardial effusion

British Library Electronic Table of Contents (United Kingdom)

Ventricular septal defects can occur as part of other congenital cardiac malformations or as an isolated finding. Aneurysms of the sinus of Valsalva are rare, most commonly involving the right or noncoronary sinuses. They can be congenital or acquired through infection, trauma, or degenerative diseases. They frequently co-exist with ventricular septal defects, aortic valve dysfunction, or other cardiac abnormalities. More commonly, sinus of Valsalva aneurysms are diagnosed after the clinical sequelae of rupture. Several etiologic factors may lead to the development of pathologic pericardial effusion and the detection of pericardial effusion was one of the first applications of echocardiography to gain widespread acceptance.

Symptomatic hepatic cyst in a child: treatment with single-shot injection of tetracycline hydrochloride

Surgical management of osteoradionecrosis of the temporal bone

The prevalence of hepatic cysts is 0.1% to 0.5% based on autopsy studies, and 2.5% based on US examinations. Percutaneous therapies are a new alternative to surgery. They include simple percutaneous aspiration, catheter drainage alone, and catheter drainage with sclerotherapy. We present an 11-year-old boy admitted to hospital because of abdominal pain. A diagnosis of simple hepatic cyst was made, which was treated with aspiration and tetracycline hydrochloride solution (5%) injection into the cystic cavity. Complete regression was seen on US and MRI examination at 3 months, with total collapse and deflation of the cyst. The cyst regressed totally, leaving a hyperechoic linear scar on US examination at 1 year. On the basis of the clinical and imaging results obtained, percutaneous sclerotherapy of hepatic cysts can be recommended as the treatment of choice and as a valid alternative to laparoscopy in children.

Subjective effects to cannabis are associated with use, abuse and dependence after adjusting for genetic and environmental influences

The surgical management of osteoradionecrosis of the temporal bone has met with limited success because of the difficulty in accurate assessment of the viability of nonnecrotic bone intraoperatively. Failure to resect all nonviable bone results in recurrence of a necrotic focus. With the use of hyperbaric oxygen therapy to stabilize marginal bone and oral tetracycline to label viable bone preoperatively, removal of all nonviable bone can be accomplished. Postoperatively, a second course of hyperbaric therapy enhances wound healing, thus assuring a successful outcome. This article details a successful systematic approach that was developed to resect a necrotic focus in the temporal bone of a 10-year-old boy who had undergone a full course of radiotherapy for treatment of a rhabdomyosarcoma.

Severe paraquat poisoning: clinical and radiological findings in a survivor

Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates, mainly due to respiratory failure. We report the case of a 22-year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission. Chest CT scans revealed pulmonary opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for ...

We report the case of a 22-year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission. Chest CT scans revealed pulmonary opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for ...

Abstract Background: Premature ovarian failure is diagnosed with a picture of amenorrhea, elevated follicle-stimulating hormone (FSH), and age under 40 years. Twenty percent (20%) of patients with premature ovarian failure have a concomitant autoimmune disease. Cases of premature ovarian failure associated with Sj?gren syndrome have been reported in the literature. Patient and method: We report a case of a 42-year-old white woman with Sj?gren syndrome and premature ovarian failure who underwent a reversal of her premature ovarian failure and restoration of normal menses using an elimination diet protocol. The patient was diagnosed with her rheumatological condition in 2005 and started on disease-modifying antirheumatoid drugs, which were taken intermittently due to a concern over medicatio...

Relationships between contraction properties of knee extensor muscles and fasting IGF-1 and adipocytokines in physically active postmenopausal women

British Library Electronic Table of Contents (United Kingdom)

Summary The aim of this cross-sectional study was to find possible relationships between insulin-like growth factor-1 (IGF-1), adipocytokines (leptin and adiponectin) and twitch contraction (TC) characteristics of the knee extensor (KE) muscles in healthy physically active postmenopausal women (n = 28, 64-78 years old). We hypothesized that IGF-1 is related at least to isometric TC peak torque (Pt) as the highest value of isometric torque production and maximal voluntary contraction (MVC) torque, and there will not be any relationships between TC characteristics and leptin and adiponectin. During the measurement of MVC torque and twitch contractile properties of KE muscles, the subjects sat in a custom-made dynamometric chair with the knee and hip angles equal to 90degree and 100degree, re...

Recovery of soil organic matter, organic matter turnover and nitrogen cycling in a post-mining forest rehabilitation chronosequence

British Library Electronic Table of Contents (United Kingdom)

Recovery of soil organic matter, organic matter turnover and mineral nutrient cycling is critical to the success of rehabilitation schemes following major ecosystem disturbance. We investigated successional changes in soil nutrient contents, microbial biomass and activity, C utilisation efficiency and N cycling dynamics in a chronosequence of seven ages (between 0 and 26 years old) of jarrah (Eucalyptus marginata) forest rehabilitation that had been previously mined for bauxite. Recovery was assessed by comparison of rehabilitation soils to non-mined jarrah forest references sites. Mining operations resulted in significant losses of soil total C and N, microbial biomass C and microbial quotients. Organic matter quantity recovered within the rehabilitation chronosequence soils to a level co...

Radioexposure of children in cranial examinations with new-generation CT equipment

Premature Failure of a Riata Defibrillator Lead Without Impedance Change or Inappropriate Sensing: A Case Report and Review of the Literature

Using phantoms of children simulating a child of 6 months of age and another one aged 6 years, the authors measured the amount of radioexposure of the lens of the eye, the thyroid and of the gonads. The two computer tomographs Somatom SF and Tomoscan 300 under examination, produced radiodoses of comparable magnitudes. Both devices allow additional examination techniques of particularly high economy. It was found that in cranial CT the exposure of the lens to radiation is generally below 1 R if the orbitae are not situated in the plane of section. If a distance of 2-3 cm is maintained from the orbitae, the dose remains below 0.5 R. Protecting the gonads is meaningful in a 6-year-old boy, whereas covering-up of the thyroid reduced the dose only slightly.

Premature Failure of a Riata Defibrillator Lead. A 63-year-old woman with a St. Jude Medical Riata 1570 right ventricular lead complained of intermittent hiccups 2 months after implant. Interrogation revealed elevated pacing threshold and diaphragmatic stimulation. Pacing and shock lead impedances remained stable. No inappropriate sensing was noted. Fluoroscopic examination of the lead revealed a thin radio-opaque wire seen between the 2 defibrillator coils away from the main body of the lead. After extraction, a tear in the insulation of the lead was noted allowing the inner wire to protrude. This case illustrates a novel mechanism of insulation failure without inappropriate sensing or impedance change.-(J Cardiovasc Electrophysiol, Vol. 22, pp. 1070-1072, September 2011)

Postoperative pressure-induced alopecia after segmental osteotomy at the upper and lower frontal edentulous areas for distraction osteogenesis

British Library Electronic Table of Contents (United Kingdom)

Introduction Postoperative alopecia is a relatively rare event, and therefore both patients and surgeons are puzzled once it develops even though it is said to improve spontaneously with time in most cases. We report a parieto-occipital pressure-induced alopecia firstly developed in a patient who had undergone repeated surgery for 10?years after a traffic accident. Case report A 29-year-old male underwent segmental osteotomy at the upper and lower frontal edentulous areas for distraction osteogenesis. Throughout the operation, he was in the supine position with the hair covered with a paper cap and the head on a plastic vinyl chloride-covered soft foam horseshoe-shaped urethane sponge placed on the horseshoe-shaped headrest. About 2?weeks after the surgery, two patches of parieto-occipital...

Photosynthesis responses to various soil moisture in leaves of Wisteria sinensis

British Library Electronic Table of Contents (United Kingdom)

A study was conducted to determine the fitting soil moisture for the normal growth of two-year-old W. sinensis (Sims) Sweets by using gas exchange technique. Remarkable threshold values of net photosynthetic rate (Pn), transpiration rate (Tr) and water use efficiency (WUE) were observed in the W. sinensis leaves treated by various soil moisture and photosynthetic available radiation (PAR). The fitting soil moisture for maintaining a high level of Pn and WUE was in range of 15.3%?26.5% of volumetric water content (VWC), of which the optimal VWC was 23.3%. Under the condition of fitting soil moisture, the light saturation point of leaves occurred at above 800?mol?m?2?s?1, whereas under the condition of water deficiency (VWC, 11.9% and 8.2%) or oversaturation (VWC, 26.5%), the light saturatio...

Paralysis due to a glomangioma in a Macaca mulatta. Final report

Orthognathic treatment with maxillary and mandibular anterior segmental osteotomy

Glomangioma have many synonyms including: glomus tumors, tumors of neuromyoarterial glomi, angioneuromas, angioneuromyomas, neuromyoarterial glomi, painful subcutaneous tubercles, Popoff tumors or subcotaneous glomal tumors. They are common in humans, rare in nonhuman primates and to the best of our knowledge, have only been reported in irradiated rhesus. The neoplasms originate in arterial-venous shunts known as neuromyoarterial glomi which are commonly found beneath fingernails and fingertips, but have been reported in many locations both superficial and deep. The neoplasm can be confused with hemangiopericytomas, hemangiomas, paragangliomas, and leiomyomas, and must be definitely diagnosed ultrastructurally. A glomangioma at the 6-7 thoracic intervertebral space caused compression of the spinal cord with posterior paralysis in an irradiated 20-year-old female rhesus monkey (Macaca mulatta).

Omental pedicle flap used to treat a bronchopleural fistula after diaphragma--pericardio-pleuropneumonectomy.

Oligodendroglioma occurring after radiation therapy for pituitary adenoma

In a 47-year-old male patient a bronchopleural fistula was apparent 22 days after extended right-sided diaphragma-pericardio-pleuro-pneumonectomy for pleuramesothelioma. The thoracic cavity was infected. Rethoracotomy was performed and the fistula was closed using an omental pedicle flap. The bronchial stump became tight and the cavity fluid became sterile. No abdominal complications were seen. The patient died 8 months later from malignant pericardial infiltration. The ability of greater omentum to revascularize ischemic tissue, to absorb fluid and to resist local infection is proved and used in several subspecialities of surgery. Nevertheless the use of the greater omentum in the management of bronchopleural fistula has been rarely published. The reported case shows that the closure of a large bronchopleural fistula is possible by using the attributes of the omental tissue. PMID:2264043

Noninvasive prediction of vertebral body compressive strength using nonlinear finite element method and an image based technique

A 38 year old male dentist developed an oligodendroglioma of the left medial temporal lobe and parasellar region 12 years after radiotherapy with 6600 rads for acromegaly. The 30 cases of radiation-induced gliomas reported in the English literature are reviewed and analysed. The criteria for defining radiation-induced tumours of the central nervous system are proposed as follows: the tumour has a long quiescent ''latency period'', a location in the previously irradiated field, a verified histological difference from a primary condition, and does not arise from a primary condition associated with a genetic syndrome such as neurofibromatosis or tuberous sclerosis. The reported case fulfilled these criteria but appears to be the only reported radiation-induced oligodendroglioma.

Noninvasive prediction of vertebral body strength under compressive loading condition is a valuable tool for the assessment of clinical fractures. This paper presents an effective specimen-specific approach for noninvasive prediction of human vertebral strength using a nonlinear finite element (FE) model and an image based parameter based on the quantitative computed tomography (QCT). Nine thoracolumbar vertebrae excised from three cadavers with an average age of 42 years old were used as the samples. The samples were scanned using the QCT. Then, a segmentation technique was performed on each QCT sectional image. The segmented images were then converted into three-dimensional FE models for linear and nonlinear analyses. A new material model was implemented in our nonlinear model being more...

Metastatic breast carcinoma to parathyroid adenoma on fine needle cytology sample: Report of a case

British Library Electronic Table of Contents (United Kingdom)

Abstract Metastases to the thyroid gland diagnosed by means of fine needle cytology or by excision have been reported in the literature. To our knowledge, metastatic neoplasms to the parathyroid gland have never been described up to now. In this article, we introduce a rare case of metastatic breast carcinoma to a parathyroid adenoma in a 56-year-old woman, which clinically simulated a left thyroid nodule. The patient had a history of left breast carcinoma; the recent discovery of a palpable mass in the left thyroid area had elicited fine needle cytology sampling for its diagnostic evaluation. The obtained cytopathological sample was cellular but limited to a single Diff-Quik-stained smear; hence, no ancillary studies could be entertained. A cytopathological diagnosis of positive for malig...

Malignant solitary fibrous tumor of the thyroid gland: Report of a case and review of the literature

British Library Electronic Table of Contents (United Kingdom)

Abstract Solitary fibrous tumors of the thyroid gland (T-SFT) are rarely described, with only 21 cases being reported in the English literatures, all showing benign clinical characteristics. We herein present a 76-year-old woman presenting with a 3-month history of rapidly enlarging neck masses and the CT showed masses with partial calcification in the right thyroid lobe. We performed right hemithyroidectomy and isthmectomy with negative margin under general anesthesia. Histologically, the masses consisted of pleomorphic spindle cells with high mitoses and collagen bands. Immunohistochemically, the tumor cells showed positive reactions for CD34, vimentin and bcl-2, then a diagnosis of malignant solitary fibrous tumor of the right thyroid was made. Six months postoperatively, the CT showed ...

MRI findings of the brain in high-voltage electrical burn patient: case report

Long-term survival following radical surgery after chemotherapy for esophagogastric adenocarcinoma with extensive lymph node metastases: Report of a case

We report the delayed sequelae arising in a case of electrical injury, reviewing the literature on the subject and focusing on the MRI findings of the brain. A 23-year-old male suffered burns to the left parietal scalp, both feet, and the anterior chest wall. Neurological symptoms and MRI abnormalities appeared 14 days after the insult and continued for about three months. T1-weight MR images demonstrated homogeneous hypointensity, while T2-weighted images depicted hyperintense finger-like projections. Contrast-enhanced T1-weighted images demonstrated strong band-like enhancement, indicating meningeal hyperemia. Follow-up MR imaging showed that the lesion had disappeared, indicating that the cerebral edema and meaningeal hyperemia were reversible.

A 46-year-old man was referred to us after he presented to his local physician complaining of difficulty eating. Upper gastrointestinal endoscopy revealed a tumor at the esophagogastric junction (EGJ), and moderately differentiated adenocarcinoma was diagnosed from the biopsy findings. Computed tomography (CT) showed apparent enlargement of the pretracheal lymph nodes, the lymph nodes around the bilateral recurrent laryngeal nerves, and the lower thoracic paraesophageal lymph nodes, confirming metastasis. Since the disease was far advanced esophagogastric cancer with marked lymph node metastases throughout the mediastinum, curative resection would have been unlikely. Thus, he was commenced on systemic chemotherapy with cisplatin (90 mg/body, day 8) + S-1 (120 mg/body/day, given for 3 weeks...

Locally invasive lymphangiosarcoma in a young domestic shorthair

British Library Electronic Table of Contents (United Kingdom)

A 2-year-old, female spayed, domestic shorthair cat presented to the University of Missouri-Veterinary Medical Teaching Hospital (UMC-VMTH) with an approximately 11-month history of fluid-draining pockets along her ventral thorax and axillae. The skin in these regions was erythematous, and multiple areas drained a serous to serosanguinous fluid. Fluid-filled, nodules formed along the ventrum, but these nodules disappeared as fluid drained spontaneously. Histologic assessment of skin biopsies revealed areas of vascular proliferation extending along the deep margin of the section and rare instances of invasion into the superficial dermis. These vascular channels were devoid of cells, lined by variably pleomorphic endothelial cells which had a low mitotic index. Based on the mild to moderate ...

Laparoscopic Transduodenal Ampullectomy for Benign Ampullary Tumors

British Library Electronic Table of Contents (United Kingdom)

Abstract Introduction: Transduodenal ampullectomy (TDA) can be performed for benign and premalignant tumors of the ampulla of Vater (AOV) as an alternative to pancreaticoduodenectomy. However, the laparoscopic approach has rarely been attempted. In this report 2 cases of benign ampullary tumor that were treated by totally laparoscopic TDA. Patients and Methods: Case 1 was of a 75-year-old female who was admitted with left knee pain and underwent arthroscopic debridement. On postoperative day 6, she showed elevated levels of alkaline phosphatase, aspirate aminotransferase, alanine transaminase, and gamma-glutamyl transpeptidase, without any other laboratory test abnormality. She had no complaint of abdominal pain, and physical examinations were unremarkable. Computed tomography (CT), magnet...

Insights gained from studies of gas pipeline rights-of-way of varying ages through wetlands

How Design-based Research, Action Research and Interaction Design Contributes to the Development of Designs for Learning

Impacts of gas pipeline rights-of-way (ROWs) through wetlands depend on types of habitat, construction techniques, final elevations, ROW maintenance practices, soil composition, and local climate. In some instances factors unrelated to the presence of the pipeline may have greater impacts on wetland modification than does the pipeline itself. At one site, the required seeding program inhibited natural reestablishment of wetland plants; at another, downstream construction resulted in a major disruption to the adjacent wetland habitat. This paper discusses observation from 13 study sites, each zero to 30 years old, that are located in seven Eastern States.

Hepatosplenic T-cell lymphoma is a distinct rare entity: Diagnosis by fine-needle aspiration cytology

This article explores how action research, design based research and interaction design can be combined and used in the development of educational robotic tools. Our case study is the development of Number Blocks and it combines physical interaction, learning, and immediate feedback. Number Blocks supports the children's understanding of place value in the sense that it allows them to experiment with creating large numbers. The development was done in collaboration with a class of 7-8 year old children and their mathematics teacher. The article argues that elements from different research methods allowed a structured approach to projects that combines educational research and innovation of new learning technologies. Key elements of this approach is acknowledging the users input, developing a theoretical pre-analysis and using an iterative approach.

Abstract In this brief report, we have described the fine-needle aspiration cytology (FNAC) of a hepatosplenic T-cell lymphoma (HSTCL) in a 60-year-old female patient. The patient complained of fever and heaviness of left upper abdomen. Ultrasound-guided FNAC of the spleen showed immature lymphoid cells, and a diagnosis of primary non-Hodgkin lymphoma of spleen was offered. Subsequently, the patient underwent splenectomy and wedge biopsy of liver that confirmed the cytological diagnosis. The lymphoma cells were positive for CD3 immunostain. Primary hepatosplenic T-cell lymphoma is a rare entity and may often pose diagnostic problems on FNAC. Diagn. Cytopathol. 2010. 2010 Wiley-Liss, Inc.

Help-Seeking for Children with Mental Health Problems: Parents? Efforts and Experiences

British Library Electronic Table of Contents (United Kingdom)

Parents who contacted 1 of 15 children?s mental health agencies in Ontario, Canada reported on where and why they were seeking mental health services for their 4- to 17-year-old children. Parents contacted?an average of four agencies (?1.7; range?=?1?14) in the previous year. Approximately one-half of parents were looking for either multiple types of treatment, or help for different problems, across agencies. The complex pattern of help-seeking evidenced in our study likely increases the burden on the mental health care system and on families, and may reduce the likelihood that families will connect with the most appropriate treatment.

Experiencing mathematics classes: Ability grouping, gender and the selective development of participative identities

British Library Electronic Table of Contents (United Kingdom)

Mathematics education reform emphasises the need to move away from transmission models of teaching to discursive classroom practices in which students negotiate and justify solutions to problems. This shift has potential, but not inevitable, implications for students' mathematical identities with respect to their sense of ownership and participation in mathematics as a creative activity, and is particularly pertinent in the UK context where ability grouping is prevalent. This paper presents an analysis of 13-15-year-old British pupils' accounts of learning and doing mathematics, and shows that the pedagogic practices of ability grouping do indeed play a major part in the development of participatory identities for some pupils but not for others. The data also show that learning is more tha...

Ewing's sarcoma recurrence vs radiation necrosis in dynamic contrast-enhanced MR imaging: a case report

Effectiveness of different music-playing devices for reducing preoperative anxiety: A clinical control study

Purpose. We report a case of Ewing's sarcoma in the right distal femur in a 6-year-old male to demonstrate how dynamic contrast-enhanced magnetic resonance imaging (DEMRI) findings predicted histopathology. Materials and methods. DEMRI was performed at presentation and during and after completion of chemotherapy and radiation therapy. Histopathologic studies were done at presentation, at 77 weeks (20 weeks after a pathological fracture), and from the en bloc resection at 104 weeks. Results. DEMRI predicted the early tumor response, absence of tumor recurrence, presence of necrosis and lack of fracture healing, confirmed by histopathology. Conclusion. DEMRI is a clinically useful tool in managing Ewing's sarcoma. (orig.)

Effect of alleviating products with different mode of action on physiology and yield of olive under drought

British Library Electronic Table of Contents (United Kingdom)

Two years old self-rooted Koroneiki olive trees (Olea europaea L.) were subjected to two irrigation regimes, i.e. the fully irrigated and the severely water stressed trees, while they were treated with three alleviating products of different mode of action. The products used were the osmolyte glycine betaine, the antioxidant Ambiol and the heat and irradiance reflecting kaolin clay particles. The effects of product application and water regime on leaf characteristics, shoot and root growth, photosynthesis, leaf compatible solids (carbohydrates) concentration and yield were evaluated. All products applied, exhibited significant alleviating action, based on the relative alleviation index. Irrigated trees exhibited greater growth than drought stressed ones, while the ameliorating products mai...

Discrimination of Korean ginseng (Panax ginseng) roots using rapid resolution LC-QTOF/MS combined by multivariate statistical analysis

British Library Electronic Table of Contents (United Kingdom)

Korean ginseng (Panax ginseng C.A. Meyer) contains several types of saponins and ginsenosides, which are usually considered the major active components of ginseng. The types and quantities of saponins found in ginseng may differ depending on the region of cultivation. As a result, ginsengs produced in different areas of Korea have been unintentionally mislabeled and/or confused by Korean herbal markets owing to their complicated plant sources. Another concern is that 4- and 6-year-old ginseng roots, traditionally prescribed for different medicinal purposes, can vary in total saponin contents. Therefore, it is necessary to establish a reliable method for distinguishing different cultivation regions and ages of ginseng roots. A rapid resolution liquid chromatography-quadruple time of flight ...

Decreased semen quality in a male infected with malaria.

Curative resection of a huge malignant pancreatic endocrine tumor by pancreatoduodenectomy with portal and superior mesenteric vein resection and reconstruction using the right ovarian vein: Report of a case

A 33-year-old male of proven fertility suffered six attacks of malaria while resident in an African country. For this he received anti-malarial drugs. Semen analysis performed after the fourth attack, and repeated during the following 2 years after his return to Israel, revealed severe oligozoospermia, necrozoospermia and occasionally even azoospermia. Immunological examination of the patient revealed an inverse ratio of T-cell subsets and mast cell degranulation in response to palludrin. Twenty-five months after the last attack of malaria a significant improvement was found in semen quality and there was an increase in the ratio of T-helper to T-suppressor cytotoxic cells. These observations indicate that although malaria and its treatment may affect spermatogenesis, recovery may be expected eventually. PMID:3500921

Concurrent immune thrombocytopenic purpura and Guillain-Barre syndrome in a patient with Hashimotos thyroiditis

British Library Electronic Table of Contents (United Kingdom)

Immune thrombocytopenic purpura (ITP), Guillain-Barre syndrome (GBS), and Hashimotos thyroiditis (HT) are autoimmune disorders caused by impaired self-tolerance mechanisms triggered by interaction between genetic and environmental factors. ITP is an immune-mediated destruction of platelets resulting in mucocutaneous bleeding, GBS is an ascending motor paralysis caused by an inflammatory demyelination of peripheral nerves, and HT is characterized by autoimmune-mediated destruction of the thyroid gland. The concurrent development of ITP and GBS has only rarely been reported in the literature, and GBS itself rarely occurs with other autoimmune disorders. We present a 21 year-old patient with known Hashimotos hypothyroidism that simultaneously developed GBS and ITP after an upper respiratory t...

Challenges in conducting clinical trials in children: approaches for improving performance

British Library Electronic Table of Contents (United Kingdom)

Recent legislative changes in both Europe and the USA have increased the responsibility of drug developers to purposefully study the agents they market in children so that specific dosing recommendations can be made to assist clinicians in their use. Typically, clinicians use empirical- or experiential-based rationales for selecting the dose to use in children, generally in a manner that attempts to achieve the same dose-exposure or pharmacokinetic profile in children as in adults. However, whether this approach achieves the necessary dose exposure or exposure effect needed may not be systematically explored during off-label use. This creates the opportunity for under- or over-exposure in children, particularly in very young children (i.e., less than 2 years old) where a combination of fac...

Case report 403: Extra-mammary Paget disease of the skin with disseminated skeletal metastases

Cardiopulmonary fitness and endurance in children with developmental coordination disorder

The case is presented of a 64-year-old man who complained on admission of discomfort in the right shoulder at the time of excision of a large section of the axillary skin which contained extra-mammary Paget disease. Shortly thereafter, radiological studies of the humerus and scapula showed obvious malignant disease which proved to be metastatic upon biopsy of the humerus and pathological studies of the excised area of extra-mammary Paget disease in the axillary skin. The patient died twelve months after the diagnosis was established with widespread metastatic disease. The literature on the subject was reviewed and it was demonstrated that metastases to the skeleton from lesions of the skin are relatively rare. This case is exceptional because of the rapid fatal course and the extent of metastatic disease originating in extra-mammary Paget disease of the axillary skin.

Bilateral primary breast neuroendocrine carcinoma in a young woman: Report of a case

British Library Electronic Table of Contents (United Kingdom)

Bilateral breast carcinoma accounts for approximately 5% of all patients with breast cancer, while neuroendocrine breast carcinomas comprise less than 5% of invasive breast carcinomas. In addition, most patients with breast neuroendocrine carcinomas are older. Therefore, bilateral primary breast neuroendocrine carcinoma at a young age is extremely rare. We herein report bilateral neuroendocrine carcinoma of the breast in a 29-year-old woman who underwent bilateral lumpectomy with the initial symptom of bilateral nipple discharge. Grossly, the lesions in both breasts were masses with infinite margins. Histologically, this case was consistent with primary neuroendocrine carcinoma arising in bilateral breasts.

Association of Externalizing Behavior Disorder Symptoms and Injury Among Fifth Graders

British Library Electronic Table of Contents (United Kingdom)

ObjectiveInjury is the leading cause of death among American youth, killing more 11-year-olds than all other causes combined. Children with symptoms of externalizing behavior disorders such as attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) may have increased risk. Our aims were to determine: (1) whether increasing symptoms of ADHD and CD associate positively with injuries among a community sample of fifth graders; and (2) whether symptoms of ADHD and CD have a multiplicative rather than additive association with injuries among the sample. MethodsData were collected from 4745 fifth graders and their primary caregivers participating in Healthy Passages, a multisite, community-based study of pediatric health risk behaviors and health outcomes. The primary outcome wa...

Alumnium phosphide fatalities at mild exertion in asymptomatic children: A clue to understand the variations of the autopsy findings

British Library Electronic Table of Contents (United Kingdom)

Fatalities resulted from aluminium phosphide (ALP) intoxication in completely healthy children with no preceded clinical sings or symptoms were presented. Data regarding circumstances, autopsy reports, histopathological examination, toxicological investigation, and police enquiries were also collected and evaluated. The affected children were females, and 6-16 years old. They were completely healthy and died suddenly in relation to some physical activities such as running, walking, and bathing, without any prior complain. The viscera showed intense congestion with moderate to severe pulmonary edema. The cause of the sudden termination of life in the reported cases is mostly cardiac ones. Physical exertion may precipitate death due to increased cardiac stress, increased oxygen demand, and b...

Aluminium Phosphide-Induced Esophageal Stricture Palliation with Polyflex Stent

British Library Electronic Table of Contents (United Kingdom)

A 21-year-old woman developed midesophageal stricture two weeks after ingestion of aluminium phosphide (AlP) tablets. Aluminium phosphide is a lethal protoplasmic toxin and is also the most common cause of suicidal poisoning in northern India. Upper gastrointestinal endoscopy (UGIE) showed a tight esophageal stricture 29?cm from the incisors with a circumferential ulcer. Dilatation up to 17?mm was done using Savary-Gilliard dilators. She had repeated dilatations three times at nearly two-week intervals. In view of the resistant stricture, a silicone Polyflex stent was placed across the stricture and removed after 3?months; there was no recurrence of stricture even after three months of follow-up. Patients with recurrent esophageal stricture and those with fistula may benefit from silicone ...

Abces du muscle iliopsoas : complication rare de la sacro-iliite a pyogene chez lenfant

British Library Electronic Table of Contents (United Kingdom)

Pyogenic sacroiliitis is a rare entity in children. Diagnosis is often delayed because of its variable clinical presentation, low suspicion by the examining physician, and rare findings on radiographs. Delayed diagnosis, however, results in complications such as iliopsoas abscess. We report the case of a 12-year-old girl hospitalized with a 21-day history of fever, pain in the left iliac fossa, and flexion contracture of the hip. On examination, she had fever (38.9 ^oC), psoitis, localized tenderness at the left sacroiliac joint, and pain elicited by lateral compression of the pelvis. The abdominal examination was normal. The erythrocyte sedimentation rate was 130mm in the first hour, C-reactive protein was 186mg/l, and the white blood cell count was 18,400/mm^3, with 79% neutrophils. Urin...

Machinery management data for willow harvest with a bio-baler

Two children with cutaneous lymphoma and leukemia who were treated with total skin electron beam therapy (TSEB) are described here. Patient 1. A 7-year-old boy was admitted because of a mass over the bilateral parotis and anemia. The white blood cell count on admission was 5,000/ul. Bone marrow examination revealed 70 per cent monoblasts (M5a type by FAB classification). Complete remission was obtained following the regimen of daunomycin, cytosine arabinoside, 6-mercaptopurine and prednisolone. He was again admitted because of a skin nodule on the left thigh 19 months after initial diagnosis. A biopsy of the skin nodule demonstrated monoblastic infiltration. He received 20 Grays (Gy) to the left thigh and this led to resolution of the skin nodule. At that time, other skin nodules appeared on the right upper and lower extremities. He was treated with TSEB. Daily doses of 1 Gy were given twice a week with a 4 MeV electron beam and a total dose of 10 Gy was ...

Investigation on the state of health (1993-1997) in ambient residents of Daya Bay Nuclear Power Plant in the early days

Willow harvested in 2-to-3-year rotations has been touted as a reliable source of biomass. A newly designed harvester based on a round baler was developed in 2006. The third generation biobaler was evaluated in 2009 at 2 willow plantations in Quebec. The first site at Godmanchester was a three-year old regrowth with an estimated 52,000 stems/ha of large diameter willow. The biobaler with a flail cutter harvested three plots totalling 4,136 m{sup 2}. Total harvested biomass was 10.36 t DM in 42 bales. The harvest rate averaged 29 bale/h with an average bale size of 1.22 m wide by 1.30 m in diameter. Diesel fuel consumption averaged 0.81 L/bale. Measured losses averaged 11 per cent of the yield. The second site at Saint-Roch-del'Achigan was a two-year old growth with an estimated 49,000 stems/ha of large stem willow. The biobaler harvested seven plots totalling 15,740 m{sup 2}.

BACKGROUND: Denys-Drash Syndrome (DDS) is an uncommon disorder that appears sporadically and in rare cases may be inherited as an autosomal dominant trait It manifests either at birth or within the first year of life and typically consists of the triad of congenital nephropathy, Wilms tumour and intersex disorder. CASE REPORT: A 10 year-old Caucasian girl was referred to the Dental Department, at Glasgow Royal Hospital for Sick Children by her Paediatric Nephrologist Consultant. The patient was being teased by her peers over her markedly discoloured teeth. The dental history revealed that the patient was a regular dental attendee from an early age. She was dentally anxious having only experienced dental treatment under general anaesthesia (GA) when she was 4 years old. Apparently her primary dentition also showed a generalised discolouration.

[Legionella pneumonia caused by aspiration of hot spring water after sarin exposure].

Use of sodium chromate Cr/sub 51/ in diagnosing childhood idiopathic pulmonary hemosiderosis

A 72-year-old man was exposed to the sarin gas attack in a Tokyo subway on March 20 th, 1995. After exposure, he noticed eye discomfort, chest tightness, headache and weakness of the lower limbs and oropharyngeal muscles. Despite these symptoms, he visited a hot spring on the same day with his family. On March 25 th, his muscle weakness progressed, and a low grade fever appeared. His muscle weakness disappeared 8 days after exposure to sarin, but respiratory failure rapidly developed, necessitating artificial ventilation within four day after hospitalization on March 28th. Chemotherapy with erythromycin, imipenem/cilastatin, and steroid pulse therapy was begu. PCR and culture of sputum collected by bronchofiberscopy were positive for Legionella pneumophila, serogroup I. His respiratory state improved, but subsequent infection with Pseudomonous aeruginosa. Enterobacter cloacae, and Candida tropicalis/glabrata caused his death 71 days after admission. Oropharyngeal ...

The Scientific Publications of Richard H. Dalitz, FRS (1925-2006)

The diagnosis of idiopathic pulmonary hemosiderosis (IPH) may be elusive. A 6-year-old boy had microcytic hypochromic anemia and a hemolytic component. Hemosiderin-laden macrophages were not found in the gastric aspirate. He had no pulmonary signs or symptoms. Extensive hematologic and roentgenologic investigations failed to reveal the cause of the anemia. Quantitative serial scintigraphic scanning showed significant (35%) pulmonary sequestration of autologous erythrocytes labeled with sodium chromate Cr51. The half-life of the RBCs was moderately decreased (half-life, 15 days; normal, 25 to 35 days). An open-lung biopsy spece Cr51. The half-life of the RBCs was moderately decreased (half-life, 15 days; normal, 25 to 35 days). An open-lung biopsy specimen confirmed the diagnosis of IPH. A diagnosis of IPH should be considered when children have iron deficiency anemia and pulmonary signs or symptoms. Organ sequestration studies may be helpful in equivocal cases.

Surgery for acoustic neurinoma treated by gamma-knife radiosurgery. A case report

Professor Richard H. Dalitz passed away on January 13, 2006. He was almost 81 years old and his outstanding contributions are intimately connected to some of the major breakthroughs of the 20th century in particle and nuclear physics. These outstanding contributions go beyond the Dalitz Plot, Dalitz Pair and CDD poles that bear his name. He pioneered the theoretical study of strange baryon resonances, of baryon spectroscopy in the quark model, and of hypernuclei, to all of which he made lasting contributions. His formulation of the ''{theta} - {tau} puzzle'' led to the discovery that parity is not a symmetry of the weak interactions. A brief scientific evaluation of Dalitz's major contributions to particle and nuclear physics is hereby presented, followed by the first comprehensive list of his scientific publications, as assembled from several sources. The list is divided into two categories: the ...

Sprengel deformity in a nine-year-old boy: diagnosis and therapy; Sprengel-Deformitaet bei einem neunjaehrigen Jungen: Diagnostik und Therapie

A 52-year-old woman had a history of left hearing loss for 5 years. An acoustic neurinoma with 3.2 cm in diameter was diagnosed and treated with gamma-knife radiosurgery (19 Gy of marginal dose) 1 year and 4 months ago. She developed headache, nausea, and visual disturbance 1 month prior to admission. Slight left facial palsy appeared after radiosurgery. Magnetic resonance imaging demonstrated the tumor with central necrosis in the left cerebellopontine angle cistern, increasing in size to 3.5 cm in diameter, and hydrocephalus. Tumor removal was performed incompletely, because of the fibrous appearance of the tumor and severe adherence with the surrounding cerebellar tissue. Facial palsy did not worsen after surgery. Since the hydrocephalus was not resolved, a right ventriculo-peritoneal shunt was inserted. The clinical course in this case suggests that tumor removal followed by radiosurgery was an approximately effective treatment for large acoustic neurinoma. ...

Root Architecture of Jarrah (Eucalyptus marginata) Trees in Relation to Post-Mining Deep Ripping in Western Australia

Up to this time the sigmoid colostomy has been widely accepted and conventional treatment for radiation-injured rectum, but patients without residual malignancy strongly desire to live without colostomy. We have tried to remove the involved rectal segments by sphincter-saving procedures. Four patients underwent these procedures, pull-through procedure in three and low anterior resection in one. Among sphincter-saving procedures, pull-through procedure was most adequate. Provided the following five conditions are fulfilled, pull-through procedure should be considered for severe radiation-injured rectum. (1) No recurrence of initial malignancy in the pelvis. (2) More than 2 cm intact rectal segment above dentate line may be preserved. (3) No radiation-injured segment in upper sigmoid. (4) No severe radiation damage in small intestine. (5) Patients under 70 year-old, with normal tonus of anal sphincter.

Abstract This research aimed to investigate coarse root systems of Jarrah (Eucalyptus marginata Donn ex Sm.) trees at a 13-year-old restored bauxite mine site in south-western Australia. Excavations in an area with small trees (low-quality site) revealed that deep ripping equipment failed to penetrate the cemented lateritic subsoil, restricting coarse roots (roots >5 mm in diameter) to the top 0.5 m of the soil profile, resulting in fewer (1,344 stems/ha) and smaller (mean height 4.5 m) Jarrah trees. An adjacent area within the same pit (high-quality site), with a stand density of 3,256 stems/ha and a mean height of 8.0 m, had a kaolinitic clay subsoil which coarse roots penetrated to the average ripping depth (1.5 m). Trees at the low-quality site did not penetrate the subsoil with their ...

Plutonium in biota from an east Tennessee floodplain forest

Mountain scale modeling of transient, coupled gas flow, heat transfer and carbon-14 migration

"2"3"9 "2"4"0Pu concentrations were measured in biota from a 30-year-old contaminated floodplain forest in Tennessee. Concentration ratios relative to soil, for plutonium in litter, invertebrate cryptozoans, herbaceous ground vegetation, orthoptera and small mammals were approximately 10"-"1, 10"-"2, 10"-"3, and 10"-"4, respectively. Concentration ratios (CR) for plutonium in biota from the floodplain forest are less than CR values from other contaminated ecosystems in the USA. Presumably, this is due to humid conditions and greater rainfall which minimize resuspension as a physical transport mechanism to biota. Plutonium and radiocesium concentrations are correlated in biota from the forest at Oak Ridge and also from Mortandad Canyon in New Mexico. The cause of the covariance between concentrations of these elements is unknown. Nevertheless, the existence of these relationships suggests that it is possible to predict plutonium in biota from radiocesium ...

Management of Ewing's sarcoma

We simulate mountain-scale coupled heat transfer and gas flow at Yucca Mountain. A coupled rock-gas flow and heat transfer model, TGIF2, is used to simulate mountain-scale two-dimensional transient heat transfer and gas flow. The model is first verified against an analytical solution for the problem of an infinite horizontal layer of fluid heated from below. Our numerical results match very well with the analytical solution. Then, we obtain transient temperature and gas flow distributions inside the mountain. These distributions are used by a transient semianalytical particle tracker to obtain carbon-14 travel times for particles starting at different locations within the repository. Assuming that the repository is filled with 30-year-old waste at an initial areal power density of 57 kw/acre, we find that repository temperatures remain above 60 degrees C for more than 10,000 years. Carbon-14 travel times to the surface are mostly less than 1000 years, for particles ...

Large intracranial vessel occlusion arising after radiotherapy for craniopharingioma. A case report and review of the literature

Forty cases of Ewing's sarcoma of various sites had attended the Department of Radiotherapy at the Wanless Hospital and the Miraj Medical Centre, attached to the Government Medical College, Miraj, Maharashtra, from January, 1970 through December, 1979. There were 28 male patients and 12 female patients in the series with a male to female ratio of 2.3:1. The youngest patient in the series was a female of 6 years of age with the tumour in the scapula and the oldest patient was a 32-year-old male with a lesion in the metacarpal bone. Sixty per cent of the cases were seen in the second decade. The average age of the patients was 13.5 years. The bones of the lower extremities were most commonly involved with the highest number (35 per cent) of the cases occurring in the femur. Involvement of the bones of the right side of the body was almost equal to that of the left side. Swelling over the site of the lesion and pain over the swelling were the most common complaints ...

Greenhouse gas flux dynamics in wetlands

Preschool-age children hold negative attitudes toward overweight peers (i.e., anti-fat attitudes), but little is known about individual differences in these attitudes. The current study investigated actual weight status and perceived body size in relation to preschool-age children's anti-fat attitudes. Sixty-nine 4-6 year-olds (61% girls) were individually interviewed about their body size perceptions using a figure rating scale and anti-fat attitudes using multiple methods (including an adjective rating scale and ratings of acceptability for different body shapes). Results suggested that children's perceived body size, not actual body size, was related to their attitudes about an overweight figure and the number of figures rated as acceptable. Children who perceived themselves as heavier held fewer anti-fat attitudes. Perceived and actual body size ratings were not related to ratings of a thin figure. This study suggests the importance of examining children's body ...

Enhanced shoot multiplication in Ficus religiosa L. in the presence of adenine sulphate, glutamine and phloroglucinol

Two important greenhouse gases, CO{sub 2} and CH{sub 4}, are closely connected to the carbon cycling of wetlands. Although virgin wetlands are mostly carbon accumulating ecosystems, major proportion of the CO{sub 2} bound annually in photosynthesis is released back to the atmosphere. Main portion of the carbon cycling in wetlands is quite fast while a small proportion of carbon diffusing from soil is released from organic matter, which may be ten thousand years old. Methane is formed in the anaerobic layers of wetlands, from where it is released gradually to the atmosphere. The decomposition in anaerobic conditions is very slow, which means that usually only a few percent of the annual carbon cycling takes place as methane. Research on CO{sub 2} fluxes of different virgin and managed peatlands was the main topic of this project during the first phase of SILMU. The measurements were made during two seasons in varying conditions in c. 30 study ...

Determinations of organ or tissue doses to survivors in Hiroshima and Nagasaki

Copy number and orientation determine the susceptibility of a gene to silencing by nearby heterochromatin in Drosophila

For the purpose of risk estimates from radiation carcinogenesis including leukemogenesis and radiation genetic effects, the biological significant dose is not the tissue kerma in air but the absorbed dose in organ or tissue with respect to carcinogenic and leukemogenic effects or genetic effects. In order to estimate organ or tissue dose from the tissue kerma in air, a ratio of the organ or tissue dose to the tissue kerma in air for survivors in Hiroshima and Nagasaki was calculated with the aid of the Snyder's mathematical phantoms constructed so as to simulate the body shape of survivors aged 5, 10 years old and adult at the time of atomic bomb detonations. The ratios were corrected for the angular distribution of atomic bomb radiations, assuming an anisotropic angular distribution for the survivors exposed to the atomic bombs in open air and the isotropic distribution for the survivors incide a Japanese house or other structures.

Comparative examinations of serum pepsinogen I, II and gastric area using computed radiography in the atrophic gastritis

The classical phenomenon of position-effect variegation (PEV) is the mosaic expression that occurs when a chromosomal rearrangements moves a euchromatic gene near heterochromatin. A striking feature of this phenomenon is that genes far away from the junction with heterochromatin can be affected, as if the heterochromatic state {open_quotes}spreads.{close_quotes} We have investigated classical PEV of a Drosophila brown transgene affected by a heterochromatic junction {approximately} 60 kb away. PEV was enhanced when the transgene was locally duplicated using P transposase. Successive rounds of P transpose mutagenesis and phenotypic selection produced a series of PEV alleles with differences in phenotype that depended on transgene copy number and orientation. As for other examples of classical PEV, nearby heterochromatin was required for gene silencing. Modifications of classical PEV by alterations at a single site are unexpected, and these observations contradict models for spreading ...

Comparative examinations of serum pepsinogen I, II and gastric area using computed radiography in the atrophic gastritis

The relationship between serum PG I, PG II levels and extent of atrophic gastritis was examined. The subjects were 64 patients (male: 32, female: 32, 51.9 years old on average) with established diagnosis of either atrophic gastritis or normal. In the X-ray gastric examination, Fuji Computed Radiography (FCR) was used to obtain clear-cut images of the gastric area. Concerning the serum PG I level, patients in the group with atrophic gastritis showed lower levels than those of the people in the group with no atrophic change, but the variation was wide, and no definite tendency was seen in the relationship between the atrophic change and the serum PG I levels. Concerning the serum PG II level, as the atrophic change progresses, the serum PG II level tended to increase gradually. A significant reduction in the PG I/II ratio was seen in the group with atrophic changes (p<0.01) in comparison with the group with no atrophic changes, and the PG I/II ...

Biological responses to the chemical recovery of acidified fresh waters in the UK

This paper provides an overview of environmental cleanup at the Los Alamos National Laboratory (LANL) and some of the unique aspects and challenges. Cleanup of the 65-year old Department of Energy Laboratory is being conducted under a RCRA Consent Order with the State of New Mexico. This agreement is one of the most recent cleanup agreements signed in the DOE complex and was based on lessons learned at other DOE sites. A number of attributes create unique challenges for LANL cleanup -- the proximity to the community and pueblos, the site's topography and geology, and the nature of LANL's on-going missions. This overview paper will set the stage for other papers in this session, including papers that present: Plans to retrieve buried waste at Material Disposal Area B, across the street from oen of Los Alamos' commercial districts and the local newspaper; Progress to date and joint plans with WIPP for disposal of the ...

Bilateral femoral neck fractures following pelvic irradiation

We report biological changes at several UK Acid Waters Monitoring Network lakes and streams that are spatially consistent with the recovery of water chemistry induced by reductions in acid deposition. These include trends toward more acid-sensitive epilithic diatom and macroinvertebrate assemblages, an increasing proportional abundance of macroinvertebrate predators, an increasing occurrence of acid-sensitive aquatic macrophyte species, and the recent appearance of juvenile (<1 year old) brown trout in some of the more acidic flowing waters. Changes are often shown to be directly linked to annual variations in acidity. Although indicative of biological improvement in response to improving water chemistry, 'recovery' in most cases is modest and very gradual. While specific ecological recovery endpoints are uncertain, it is likely that physical and biotic interactions are influencing the rate of recovery of certain groups of organisms at ...

Aggressive Ewing's sarcoma appearing as a cold lesion on bone scan

Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but ...

Acute myelogenous leukemia following chemotherapy and radiation for rectal cancer

Ewing's sarcoma classically presents as a hot spot on bone scan as a result of increased vascularity of the tumor and new bone formation. Purpose We report and analyze an uncommon pattern of a 'cold' lesion in Ewing's sarcoma on bone scan and its pathophysiologic significance. Case report A 15-year-old boy complaining of thigh pain. CT scan evoked Ewing's sarcoma or osteitis. MRI evoked chronic osteitis. Scintigraphy showed a fairly intense and heterogeneous uptake on the femoral lesion and no abnormal uptake elsewhere. Biopsy showed none pathologic pattern. Three months later, a second biopsy concluded to Ewing's sarcoma. Bone scan showed a larger lesion with peripheral intense uptake centered by enlarged 'cold' area in the left femoral diaphysis and no evident bone metastasis. The patient underwent chemotherapy and surgery. Three months later, bone scan showed extensive skeletal metastasis. Conclusion Ewing's sarcoma appears usually as an intense lesion on bone ...

Lyophilized human whole blood for internal and external quality assurance of lead in blood assays

In August 1982, a 44-year-old man was diagnosed as having rectal cancer, histologically diagnosed as well differentiated adenocarcinoma, and abdominoperineal resection and colostomy were performed. Postoperatively, he received chemotherapy with mitomycin C up to a total dose of 100 mg. In September 1986, lung metastasis occurred and he was treated with a combination chemotherapy consisting of cisplatin, pirarubicin and 5-fluorouracil. In the following year, radiation treatment (total: 6900 rad) was given for a recurrent pelvic lesion. Peripheral blood on April 30, 1988, showed anemia, thrombocytopenia and appearance of myeloblasts, and a diagnosis of acute myelogenous leukemia (FAB: M1) was made. Combination chemotherapy (including aclarubicin, vincristine, behenoyl ara-C, daunorubicin, 6-mercaptopurine, cytarabine, etoposide and prednisolone) failed to induce remission and the patient died in June 1988. This case was thought to be one of secondary leukemia ...

Water-level variations and their effects on tree growth and mortality and on the biogeochemical system at the phytoremediation demonstration site in Fort Worth, Texas, 1996-2003

Endurance-trained older men have a higher proportion of lean tissue and greater muscle cell oxidative capacity, reversing age-related trends and suggesting major changes in protein metabolism. In this study, protein turnover was determined in 6 middle-aged (52+/-1 yr) men who were well trained (VO_2 max 55.2+/-5.0 ml O_2/kg.min) and lean (body fat 18.9+/-2.8%, muscle mass 36.6+/-0.6%). The maintained habitual exercise while consuming 0.6, 0.9 or 1.2 g protein/kg.day for 10-day periods. N flux was measured from "1"5N in urea after oral "1"5N-glycine administration. Myofibrillar protein breakdown was estimated from urinary 3-methyl-histidine. Dietary protein had no effect on turnover rates, even when N balance was negative. Whole body protein synthesis was 3.60+/-0.12 g/kg.day and breakdown was 3.40+/-0.14 g/kg.day for all N intakes. Whole body protein flux, synthesis and breakdown were similar to values reported for sedentary young (SY) or ...

Dynamic quantitative bone scintigraphy in patients with prostatic carcinoma treated by orchiectomy

Previous work suggests that supplemental ascorbic acid (AA) may inhibit intestinal copper absorption by stabilizing the less absorbable cuprous state. The authors studied copper absorption in healthy men (age 19-32) fed a constant diet with different amounts of ascorbic acid supplements. The 6 men were confined to a metabolic unit for the entire 14 week study. The basal diet consisted of a 7 day rotating menu which provided an average of 2.1 mg Cu/d and was adequate in all other nutrients except AA (5 mg/d). The basal diet was supplemented with either zero, 60, or 600 mg of AA daily, added to grape juice and consumed at each meal. All feces were collected. Blood was taken weekly for monitoring AA and copper status. Copper absorption was determined by both balance and "6"5Cu stable isotope techniques. As determined by fecal Cu excretion, varying intakes of AA between 0.1 to 10 times the RDA had no significant effect on copper retention. This is ...

Self-valued health in Danish women after cervix cancer surgery-A retrospective questionnaire study

Dynamic quantitative bone scintigraphy was performed on 31 men with prostatic carcinoma before orchiectomy as well as 2 weeks, 2 and 6 months postoperatively. After injection of technetium methylene diphosphonate Tc 99m ("9"9"mTc-MDP) the count rate was recorded as serial images over the lower thoracic and all the lumbar vertebrae from 1 to 240 min post-injection. Thirteen men had normal bone scintigrams with no changes in "9"9"mTc-MDP content at the four different investigation times. Eighteen men had skeletal metastases. Throughout the study half of the abnormal vertebrae in these patients showed an abnormal count rate after only 6 min post-injection. After 1 h it was possible in almost all abnormal vertebrae to predict abnormal bone uptake. In response to therapy a 'flare phenomenon' with an increase in count rate was seen 2 weeks after orchiectomy followed by a decrease 2 months postoperatively in most of the abnormal ...

Renewable Energy in Danish Municipalities - an Evaluation of The Planning Framework for Wind Power

Policies to promote sustainable consumption: Innovative approaches in Europe

Wind power is a maturing technology that in a number of countries is likely to contribute a major share to fully renewable energy systems. Denmark has a comparably long history of wind power development and is planning to continue expanding the existing capacity. If a large-scale penetration of wind power is to be achieved, an integrated framework is needed that can respond to the associated challenges. This paper argues for adopting an integrated macro perspective when evaluating and building frameworks to support wind power development. This macro perspective is applied to the case of Denmark, and more specifically to concrete wind power projects in the region of Northern Jutland. The results suggest although certain elements in the legislation have been improved, the feasibility of wind power projects cannot be guaranteed, and there is a tendency to exclude smaller turbines from the development.

Abstract Policy-makers are increasingly recognising that the promotion of more sustainable consumption patterns is an indispensable prerequisite for achieving sustainable development in the long term. Policy documents and action plans have been published, and a wide array of policy instruments has been implemented with the aim of reducing the environmental and social burdens of consuming goods and services. But what are the latest trends and innovative approaches in sustainable consumption (SC) policies? What could be learnt for future policy-making? Based on an overview of European policy instruments and several case studies, the paper discusses instructive examples of SC policy instruments, in particular the Danish information campaign "One Tonne Less", the Dutch tax incentive scheme "Gr...

Parental Subfecundity and Risk of Decreased Semen Quality in the Male Offspring: A Follow-up Study

British Library Electronic Table of Contents (United Kingdom)

A few studies have found poor semen quality in sons whose mothers have received fertility treatment, but it is unknown whether the poor semen quality is related to the infertility treatment or to infertility per se, for example, whether it is caused by hereditable factors. Using data from a population-based, Danish follow-up study conducted in 2005-2006, the authors of the present study examined whether sons of subfertile couples who had not received fertility treatment had poorer semen quality than sons of fertile couples. Among the 311 participants, an inverse association between parental waiting time to pregnancy and both semen volume and total sperm count was observed (p trend = 0.04 and p trend = 0.046, respectively). Semen volume in sons of subfertile parents (pregnant after ?1 ye...

The article criticizes the authorities for not supporting the upgrading of hydroelectric power plants in their eager to promote the development of wind power. An important contribution of the planned project will be a book from which the utilities may get advice on measures of upgrading. Generators and control systems account for 80% of the faults and interruptions in the power utilities. The turbine technology has made important progress in the 1990s. By pure upgrading measures alone, the turbine efficiencies may be increased enough for an additional 3 TWh to be taken out from the Norwegian hydroelectric power system. Today, the price of imported carbon-based Danish power determines whether the utilities find it profitable to rehabilitate the hydroelectric plants. The energy potential of upgrading is estimated to be 5 TWh. This energy can be generated ...

This guide accompanies the following article: Gabrielle Poeschl, `What Family Organization Tells Us about Fairness and Power in Marital Relationships', Social and Personality Compass 1/1 (2007): 557-571, 10.1111/j.1751-9004.2007.00026.x Author's Introduction One thing that often strikes me, when I talk with people, is the human capacity to accept and defend surprising aspects of the social life. Thus, we have some feeling that the separation between the domestic and the public spheres has not always existed, but we are ready to assume that in the first human groups, men went out hunting to feed their family, while women stayed in the camp to take care of the children. Even in the face of evidence to the contrary, we are reluctant to question the opinion that men and women differ in persona...

Psychometric properties of a scale measuring negative attitudes toward overweight individuals.

Outcomes of extremely low risk prostate cancer following radical prostatectomy

This study examined the psychometric properties of the Anti-fat Attitudes Scale (AFAS), a 5-item instrument developed by the authors to measure negative attitudes toward overweight individuals. A total of 4 studies were conducted among Canadian adolescents (n = 1,452) and university students (n = 424). Results suggested that the AFAS possessed a unidimensional factor structure and satisfactory reliability for both men and women. As predicted, men obtained higher scores than women on the AFAS, and antifat attitudes were positively associated with authoritarianism, homonegativity, and political conservatism. Participants who were overweight had lower scores on the AFAS than participants who were thin or average weight. Responses on the AFAS did not appear to be contaminated by social desirability bias.

The optimal management of men with very favorable clinicopathological factors who develop biochemical recurrence (BCR) after radical prostatectomy (RP) has not been previously reported. Both local and systemic recurrences are unlikely in this cohort. This study examines their management and outcomes. Between October 2000 to March 2010, 1627 men underwent open RP by a single surgeon. In all, 448 (27.5%) met the following criteria for extremely low risk disease: preoperative PSA level <10?ng?ml?1, clinical stage T1c/T2a, Gleason score ?6, estimated cancer volume in the surgical specimen ?5% and no evidence for positive surgical margin. Undetectable PSA was defined as ?0.04?ng?ml?1. BCR was defined as PSA ?0.2?ng?ml&#...

Oppenheimer&Groves : The duality that led to Trinity /.

Bilateral but not Unilateral Testicular Hypotrophy Predicts for Severe Impairment of Semen Quality in Men with Varicocele Undergoing Infertility Evaluation

The alliance of J. Robert Oppenheimer, scientist, and Leslie R. Groves, military leader, is often interpreted as the classic example of the clash between the academic mind and the military style. Evidence suggests, instead, that it was a collaboration that led to the dawn of the nuclear age. Instead of a clash, it was collaboration and an implosion of the diverse talents needed for the success of this project. Discussion of these flawed and fascinating individuals still ignites controversy today. This presentation will explore the backgrounds and personalities of these two men and their work together to accomplish their mission. Was the aftermath inevitable, given a relationship based on respect, but perhaps not trust? The genesis of the modern military-industrial complex rested on the genius of these two men, though they personify two distinct American sub-cultures. What lessons can be drawn from their wartime and post-war relationship? What ...

ObjectivesVaricocele is a common cause of infertility, and varicocele-associated testicular hypotrophy has been described as a potential cause of decreased semen quality. We investigated the relationship between testicular hypotrophy and poor semen quality in infertile men with varicoceles. We hypothesized that bilateral hypotrophy is required before the semen quality is severely impaired.MethodsWe retrospectively identified consecutive patients with palpable varicoceles undergoing an infertility evaluation at a single academic center. Each patient was evaluated by the same clinician with history and physical examination. Testicular hypotrophy was defined as a size discrepancy of greater than 3 mL or an absolute size of less than 14 mL. Multivariate logistic regression analysis was used to...

[Peritonitis in the course of peritoneal dialisis caused by Haemophilus influenzae with BLNAR phenotype].

Unsolved problems in the diagnosis and surgical treatment of intramedullary tumors

Most common bacterial species causing peritonitis in the course of peritoneal dialysis (PDP) are coagulase-negative staphylococci, Staphylococcus aureus and streptococci. Haemophilus influenzae is rarely associated with PDP. Hereby we present the first known case of APD-associated peritonitis caused by non-type able H. influenzae (NTHi) presenting the beta-lactamase negative, ampicillin-resistant (BLNAR) phenotype. An 18 year old boy who had been treated with the APD for 12 months due to SLE was admitted in good general condition with diagnosis of PDP. Standard diagnostic and therapeutical procedures were initiated. Dialysis fluid was turbid with cytosis of 435 WBC/ml. From dialysis fluid pure culture of Gram-negative coccobacillus was isolated. The isolate was identified as a BLNAR phenotype. The same bacterium was isolated from nasal swab. Blood cultures were negative. After evaluation of antimicrobial susceptibility the treatment was changed ...

Translocation of /sup 14/C-sucrose from mesophyll to vein and stem bark in mulberry plant

Problems and solutions in the diagnosis and operative treatment were clarified by retrospective evaluation of cases of intramedullary tumor in which MRI and surgery had been performed. The subjects were 16 patients (21-75 years old, mean age: 45 years) whose tumor was surgically removed between 1991 and 1998. MRI was performed preoperatively, and T1-weighted images, T2-weighted images, and enhanced images were obtained. Angiography was also performed in some cases. The histological diagnosis based on the MRI findings before surgery were compared with the pathological diagnosis after the operation. In 9/16 cases (56%), the preoperative histological diagnosis based on the MR images was the same as the pathological diagnosis after the operation. In 8 of the 11 cases (73%) whose images showed clear tumor margins and well shaped the tumor, the tumors were completely removed. The concordance rate between the pathological diagnosis during and after ...

The greenhouse gases N{sub 2}O, CH{sub 4} and CO{sub 2} in coniferous forest soils as influenced by nitrogen input, acidity, moisture and temperature; Drivhusgassene N{sub 2}O, CH{sub 4} og CO{sub 2} i barskogsjord under paavirking av N-tilfoersel, surhet, fuktighet og temperatur

One-year-old seedlings of mulberry, the variety of Shinichinose, were used to fix /sup 14/CO/sub 2/ for 10 minutes under light of 18,000 lux at 28 deg C. Photosynthesis was continued after that in the air not containing /sup 14/CO/sub 2/. The specimens were collected immediately after and 10 and 30 minutes after the /sup 14/CO/sub 2/ fixation, divided into mesophyll, vein and stem bark, frozen in liquid N/sub 2/, and the contents of sucrose, glucose and fructose and their radioactivity were measured. The ratio of the radioactivity incorporated into sucrose to the total radioactivity incorporated into each tissue was very large, and the incorporation into glucose or fructose was very little. The content of sucrose was also larger than that of the other sugars in all the tissues. These findings showed that the photosynthates were translocated mainly in the form of sucrose. The ratio of specific radioactivity (dpm/mg sugar) in the mesophyll to that in the vein was ...

The effect of elevated carbon dioxide on a Sierra-Nevadan dominant species: Pinus ponderosa

The thesis relates to an investigation done on greenhouse gases in coniferous forest soils. The production of nitrous oxide (N{sub 2}O) and carbon dioxide (CO{sub 2}), and the consumption of methane (CH{sub 4}) in a temperate forest soil were studied by a rapid and sensitive gas chromatographic (GC) method for analysing all three greenhouse gases at or below ambient levels. Gas fluxes were measured in soil incubation and lysimeter experiments. 15 soil samples were taken at random within a 100 m{sup 2} area in a Norway spruce forest stand (Picea abies). The fluxes of N{sub 2}O, CH{sub 4} and CO{sub 2} were measured under standardized laboratory incubation conditions to investigate spatial variability in relation to other factors such as nitrogen (N) mineralization rate, nitrification rate, organic carbon (OC), total N and pH. The effects of temperature, soil moisture content, and ammonium addition were also studied in an incubation experiment. A more detailed study was made of the ...

Results of the remote sensing feasibility study for the uranium hexafluoride storage cylinder yard program

The impact of increasing atmospheric C0{sub 2} has not been fully evaluated on western coniferous forest species. Two year old seedlings of Pinusponderosa were grown in environmentally controlled chambers under increased C0{sub 2} conditions for 6 months. These trees exhibit morphological, physiological, and biochemical alterations when compared to our controls. Analysis of whole plant biomass distribution has shown no significant effect to the root to shoot ratios, however needles subjected to elevated C0{sub 2} exhibited an increased overall specific needle mass and a decreased total needle area. Morphological changes at the needle level included decreased mesophyll to vascular tissue 91 ratio and variations in starch storage in chloroplasts. The elevated CO{sub 2} increased internal CO{sub 2} concentrations and assimilation of carbon. Biochemical assays revealed that ribulose-bisphosphate carboxylase specific activities increased on per unit ...

Renal artery stenosis after radiotherapy for Ewing's sarcoma

The US DOE manages the safe storage of approximately 650,000 tons of depleted uranium hexafluoride remaining from the Cold War. This slightly radioactive, but chemically active, material is contained in more than 46,000 steel storage cylinders that are located at Oak Ridge, Tennessee; Paducah, Kentucky; and Portsmouth, Ohio. Some of the cylinders are more than 40 years old, and approximately 17,500 are considered problem cylinders because their physical integrity is questionable. These cylinders require an annual visual inspection. The remainder of the 46,000-plus cylinders must be visually inspected every four years. Currently, the cylinder inspection program is extremely labor intensive. Because these inspections are accomplished visually, they may not be effective in the early detection of leaking cylinders. The inspection program requires approximately 12--14 full-time-equivalent (FTE) employees. At the cost of approximately $125K per FTE, ...

Quantitative risk assessment using the capacity-demand analysis

Background: the fact that therapeutic irradiation can induce significant stenosis in the arteries of the head, neck, and chest, as welt as in the aorta and the iliac arteries, is familiar in daily practice and well documented in the literature. By contrast, radiation-induced renal artery stenosis seems to be a less widely known complication. Patients and methods: the sudden onset of medically refractory arterial hypertension and coma in a 27-year-old man is reported, who had been treated at age 20 with chemotherapy and radiotherapy for Ewing's sarcoma in the lumbar region. This treatment had been performed at the hospital of Sion, Switzerland in 2001. Also, the relevant literature from 1965 to 2007 is reviewed to underscore various aspects of this problem and to demonstrate the clinical relevance of renal artery stenosis as a potential long-term sequela of radiotherapy. Conclusion: radiation-induced renal artery stenosis has only rarely been described in the ...

Preventing surgical fires: who needs to be educated?

The hydroelectric industry's recognition of the importance of avoiding unexpected failure, or forced outages, led to the development of probabilistic, or risk-based, methods in order to attempt to quantify exposures. Traditionally, such analysis has been carried out by qualitative assessments, relying on experience and sound engineering judgment to determine the optimum time to maintain, repair or replace a part or system. Depending on the nature of the problem, however, and the level of experience of those included in the decision making process, it is difficult to find a balance between acting proactively and accepting some amount of risk. The development of a practical means for establishing the probability of failure of any part or system, based on the determination of the statistical distribution of engineering properties such as acting stresses, is discussed. The capacity-demand analysis methodology, coupled with probablistic, risk-based analysis, permits all the factors ...

Native kidney reincarnation following a failed transplant

BACKGROUND AND CASE STUDY: Surgical fires are rare but preventable. During facial surgery for a 68-year-old man, a fire broke out, resulting in first- and second-degree burns after a nasal cannula ignited in an oxygen-rich environment because of improper draping and tenting. DISCUSSION: Operating room (OR) fires can be prevented if any component of the "fire triangle"-fuels, ignition sources, and oxidizers-is reduced or eliminated. The use of supplemental oxygen in the OR via nasal cannulae, nebulizers, and oxygen cylinders must always considered a potential source of fire. Deficits in knowledge among the surgical team with respect to the prevention and management of surgical fires were apparent. A plan was put into place to improve fire safety education, entailing an educational program that is included in intern and resident orientation. Surgical fire safety training was also put into place for anesthesia and surgical faculty. The anesthesia preoperative ...

Management of dams for the next Millennium: proceedings of the 1999 Canadian Dam Association

Full text: A 51-year-old woman with end stage renal failure secondary to Haemolytic Uraemic syndrome underwent a cadaveric renal transplant. A routine post transplant DTPA scan was performed which demonstrated satisfactory renal transplant perfusion and function. Incidental note was made of tracer uptake in the pelvis in the mid-line, which was suspected to be a uterine fibroid. This was confirmed on ultrasonography and at surgery. One week post transplantation the patient became acutely unwell and at laparotomy a perforated diverticular abscess was drained. Intraoperatively the transplant kidney was examined and the surgeon thought there was a area of infarction. This was confirmed on biopsy. As the patient's creatinine was rising a repeat DTPA study was performed. Perfusion and function of the transplant kidney was virtually absent while Doppler studies showed no flow. The patient however continued to produce urine and the creatinine was stable. Subsequently a ...

Incredible Years Parent Training Support for Nursery Staff Working within a Disadvantaged Flying Start Area in Wales: A Feasibility Study

A 36-year-old woman underwent amniocentesis for advanced maternal age. The fetal karyotype had an extra dark staining G band on the long arm of chromosome 11 with no other identifiable abnormalities. FISH studies using a chromosome 11 paint probe confirmed the origin of the extra band. The abnormality was identified as a partial duplication of 11q: 46,XX dir dup (11)(q13.5q21) or (q21q23.1). The specific duplicated band could not be identified with certainty. Detailed fetal sonograms were normal. Family studies revealed the identical duplication in the mother but normal karyotypes in both maternal grandparents. The mother had strabismus and a short tongue frenulum which required surgical correction. Menses occurred late in adolescence and complete development of secondary sexual characteristics was delayed until adulthood. An infertility evaluation revealed duplication of the uterus, cervix, and vagina. An evaluation for metorrhagia identified a pituitary adenoma ...

Growth of Pinus radiada in soil containing solid waste from the kraft pulp industry

Parenting programmes are effective interventions for preventing and treating conduct problems in young children. Up to 20% of children in disadvantaged areas have conduct disorder. Recent government initiatives such as targeting early years services to designated disadvantaged Flying Start areas in Wales have resulted in increased nursery-care provision for pre-schoolers, yet little has been done to equip nursery staff with effective child behaviour management strategies. The purpose of this non-randomised trial platform study was to establish the feasibility of delivery and the effectiveness of the new Incredible Years Toddler Parent Programme in supporting nursery staff in managing difficult behaviour in the nursery. The Parent Programme is a 12-session (a two-hour session/week) course for carers/parents of children aged one to three years old, which encourages carers to: establish positive relationships with children through play and ...

Comparison of normal adult and children brain SPECT imaging using statistical parametric mapping(SPM)

The germination and growth of Pinus radials Don. plantlets in solid residues deriving from a Kraft pulp industry was evaluated. Plant conditions were monitored by histological studies of roots and shoot-tips, as well as by plant analyses of several essential and non essential elements. The solids employed consisted of ashes, fly-ashes, dregs, grits, primary sludge, brown stock screening rejects and various mixtures of them. Their addition, in a range of combinations to sandy/metamorphic or marine terrace/clay soils, resulted in effective and sustained growth under greenhouse conditions. Low proportions of wastes favored growth in most cases, indicating that they may act as fertilisers. In some experiments, especially in those where waste was added in proportions ranging from 50% to 60%, germination and/or development were slightly affected. Two-year old field experiments have confirmed that in spite of the high pH values, Na ion content or ...

Articular chondrocyte metabolism and osteoarthritis

The world`s population of research reactors is growing old. Many have been adapted to serve new purposes over their lives, from testing materials for nuclear power programmes and supporting neutron physics experiments, to colouring gemstones, doping silicon and generating medical isotopes. In the first article of this survey of research reactor issues, Wilfried Krull from GKSS in Germany describes the effects on a reactor of supporting these changes in application as ``design ageing`` . Managing this and other symptoms of ageing to extend plant life is a key task for operators, and Krull discusses the efforts being made internationally to handle them. Eventually, terminal decline of one vital component can determine when a reactor has to be shutdown for refurbishment. For BR2 in Belgium, it was the beryllium matrix. Edgar Koonen from SCK-CEN explains work being done to replace it and extend reactor life for around 15 years. The Triga at the University of Austria`s Atomic Institute has ...

A study on the mineral density of the lumbar vertebral bone in children of metabolic disorders and control using single energy quantitative CT

The three main objectives of this study were: (1) to determine if depletion of proteoglycans from the cartilage matrix that occurs during osteoarthritis causes a measurable increase of cartilage proteoglycan components in the synovial fluid and sera, (2) to observe what effect intracellular cAMP has on the expression of matrix components by chondrocytes, and (3) to determine if freshly isolated chondrocytes contain detectable levels of mRNA for fibronectin. Canine serum keratan sulfate and hyaluronate were measured to determine if there was an elevation of these serum glycosaminoglycans in a canine model of osteoarthritis. A single intra-articular injection of chymopapain into a shoulder joint increased serum keratan sulfate 10 fold and hyaluronate less than 2 fold in 24 hours. Keratan sulfate concentrations in synovial fluids of dogs about one year old were unrelated to the presence of spontaneous cartilage degeneration in the joints. High ...

The relationship between seminal plasma zinc levels and high molecular weight zinc binding protein and sperm motility in Iraqi infertile men

Hormone levels were examined in the venous blood in 54 men suffering from stage 2 alcoholism and in 30 normal subjects, using a radioimmunochemical assay. The alcoholics were found to have a statistically significant increase in prolactin and a decrease in testosterone. A definite ratio in the secretion of these hormones differing from that in the control group was elucidated. This ratio (prolactin-testosterone index) is proposed as a diagnostic test of alcoholism.

Shorter anogenital distance predicts poorer semen quality in young men in Rochester, New York

Physical activity at work and job responsibility as risk factors for fatal coronary heart disease and other causes of death.

In male rodents, anogenital distance (AGD) provides a sensitive and continuous correlate of androgen exposure in the intrauterine environment and predicts later reproductive success. Some endocrine-disrupting chemicals can alter male reproductive tract development, including shortening AGD, in both rodents and humans. Whether AGD is related to semen quality in human is unknown.

The new IC3 intercity train. Modern diesel trainsets for the Danish State Railways

Full text: Immunoassays for prostate-specific antigen (PSA) are used to detect early-stage prostate cancer, monitor disease progress, and evaluate therapeutic response. At least two forms of PSA, free PSA (F-PSA) and PSA complexed to alpha-1 anti-chymotrypsin (PSA-ACT) are detected by commercial PSA assays. The fraction of F-PSA is shown to be smaller in patients with untreated prostate cancer than in patients with benign prostate hyperplasia (BPH). Thus, combined measurements of both total and free PSA are used for a better discrimination between BPH and prostate cancer. Detection of PSA for screening of prostate cancer has been a subject of debate for many years. The reason of this debate is mainly because screening for prostate cancer is not cost-effective, as was shown by studies undertaken in Europe and United States. In Lebanon, no previous programs of screening for prostate cancer were done and so the incidence of this cancer is not known. Recently, the cancer registry in ...

Reliability analysis for wind turbines with incomplete failure data collected from after the date of initial installation

An ambitious development programme culminated in late 1989 with the most modern diesel train available today entering commercial service. At the root of its development lay an overall concept which aimed at meeting the present-day and future requirements of railway administrations. Higher passenger revenues, lower operating costs and reduced maintenance are the result. An IC trainset is 58.8 m long and consists of three cars: Two identical power cars and one intermediate car. Each three-car trainset has 144 seats, 16 of which are reserved for first class. Up to five three-car trainsets can be coupled rogether to form a 15-car trainset. Four air-cooled 8-cylinder diesel engines with a combined rating of 294 kW power each three-car trainset, i.e. there are two engines installed in each of the power cars. The train has a maximum speed of 180 km/h. (orig.).

Prospects for controlling animal parasitic nematodes by predacious micro fungi.

Reliability has an impact on wind energy project costs and benefits. Both life test data and field failure data can be used for reliability analysis. In wind energy industry, wind farm operators have greater interest in recording wind turbine operating data. However, field failure data may be tainted or incomplete, and therefore it needs a more general mathematical model and algorithms to solve the model. The aim of this paper is to provide a solution to this problem. A three-parameter Weibull failure rate function is discussed for wind turbines and the parameters are estimated by maximum likelihood and least squares. Two populations of German and Danish wind turbines are analyzed. The traditional Weibull failure rate function is also employed for comparison. Analysis shows that the three-parameter Weibull function can obtain more accuracy on reliability growth of wind turbines. This work will be helpful in the understanding of the reliability growth of wind energy ...

Non-seminomatous testicular germ cell tumours in Denmark 1976-1980. Results of treatment

Resistance against anthelmintics is widespread, particularly in parasitic nematode populations of small ruminants. Several new techniques or supplements have been developed or are under investigation. Biological control (BC) is one of these new methods. The net-trapping predacious fungus Duddingtonia flagrans produces thick walled resting spores, chlamydospores, which are able to survive passage through the gastrointestinal tract of cattle, horses, sheep and pigs. Under Danish climatic conditions it has been shown that the number of parasite larvae on pasture and the worm burden of the grazing animals is significantly reduced when animals are fed spores during the initial 2-3 months of the grazing season. Work with D. flagrans in France, Australia, USA, and Mexico has confirmed the strong BC potential of this fungus. Today much work is going into development of suitable delivery systems for grazing livestock worldwide. Ultimately, BC should be implemented in ...

Non-seminomatous testicular germ cell tumours in Denmark 1976-1980

Over a 5-year period (1976-1980) 499 patients with non-seminomatous testicular germ cell tumours were included in the Danish Testicular Carcinoma Study (DATECA). The 3-year crude survival for patients in clinical stages I, II and III was 91, 77 and 45 per cent, respectively. In stage I the relapse-free survival for patients given radiation combined with bleomycin and vincristine was significantly higher than that for patients given radiation alone. No difference in the crude survival for patients given radiation combined with bleomycin and vincristine was significantly higher than that for patients given radiation alone. No difference in the crude survival was observed. For stage II patients maintenance chemotherapy following radiation combined with bleomycin and vincristine did not improve relapse-free or crude survival. The survival of patients with non-seminomatous tumours improved significantly during the 5-year period. This improvement was probably due to the ...

Hepatitis B immunization coverage and risk behaviour among Danish travellers Are immunization strategies based on single journey itineraries rational?

Sequence stratigraphic interpretation of paralic successions is complicated by the complex interfingering of marine and continental strata. The successions may also include terrestrial extensions of marine parasequences and completely independent lacustrine parasequence analogues. Failure in recognizing the possible interbedding of these two independent parasequence types may lead to construction of sequence stratigraphic schemes based on incompatible data sets. We have studied a Lower Jurassic paralic section from the Baltic island of Bornholm. The Hettangian-Sinemurian Sose Bugt Member (Ronne Formation) of Bornholm includes lacustrine, fluvial and restricted marine, estuarine deposits reflecting the basin-margin position. Biostatigraphic resolution is poor and a sequence stratigraphic interpretation of the paralic succession is far from straightforward. A multidisciplinary approach including facies analysis, recognition and lateral tracting of key surface, palynostratigraphy, ...

Emission factors of polybrominated diphenyl ethers (PBDEs) from plastics processing and recycling facilities

OBJECTIVES: The authors examine the rationale and efficacy of pre-travel hepatitis B immunization strategies based on itinerary and presumed on-travel risk behaviour. METHODS: A large survey among 26,640 Danes survey provided data on journey lengths and destinations, immunization coverage, risk behaviour and knowledge. RESULTS: The estimated cumulative lifetime stay in endemic areas outside Europe is 4.3 months. The majority of risk situations are involuntary and unforeseeable. The majority of risk situations occur on short-term journeys. 5% nonimmune and 5% short-term travellers experienced at least one risk situation such as injections/operations/tattoos on their journey. The level of knowledge of hepatitis A and B is low. CONCLUSIONS: The rationale and efficacy of current immunization strategies are challenged. Based on the results presented here and the availability of vaccines with long-lasting coverage, the authors find that recommendations of immunization should be based on ...

Consumer choice and suggested price for pork as influenced by its appearance, taste and information concerning country of origin and organic pig production

With regard to polybrominated diphenyl ether (PBDE), there is few scientific knowledge on the emission patterns into the environment and exposure pathways to humans, and basic information is insufficient to consider what measures effective are. For the purpose of promoting risk reduction of target substances more effectively and efficiently, it is desirable to comprehend accurately the causal chain from the target substances utilization to the risk intake, and to evaluate the measures covering the whole applications of target substances. As the existing researches on the PBDE emission inventory, there are EU risk assessment report (European Chemical Bureau 2000, 2002, 2003), Danish EPA (1999), Palm et al.(2002) and Alcock et al. (2003). In addition, emissions of DecaBDE are published in TRI (Toxic Release Inventory) of US EPA. However, the primary information of the previous inventories is often the same and estimations based on the measured values are few. In ...

Anaerobic digestion as a slurry management strategy : a consequential life cycle assessment

Reactions of consumers to the appearance and taste of pork with and without information concerning outdoor production of pigs were tested in France, Denmark, Sweden and UK. Consumers in all four countries focussed on colour and fatness rather than marbling and drip to make their choice. Almost half of the British and Danish preferred the paler and the French the darker pork. Most people preferred the leaner pork. When information was provided in the form of labels, the vast majority of consumers preferred the pork labelled as originating from their own country as opposed to 'imported' and that labelled as pork from pigs 'raised outside' as opposed to 'inside'. There was no difference in the taste of grilled pork from indoor and outdoor production systems but pork labelled 'home produced' or 'outdoor' were more appreciated. Consumers' willingness to pay varied widely and was higher for those consumers who found more of the characteristics they sought. Consumers ...

Computed tomography of the mediastinal lesion

Anaerobic digestion of slurry represents an environmental opportunity for both slurry management and renewable energy production in countries with high animal density. This study evaluated the environmental impacts of 4 biogas production alternatives in which slurry was the only input in the process, without supplementary addition of easily degradable carbon. This was achieved by exposing the slurry to different separation technologies. The biomass mixture input for biogas production included solid fraction from slurry separation as well as raw slurry, proportioned in order to achieve economical methane yield. The separation processes considered in this study were mechanical separation; mechanical separation combined with the addition of flocculants; and mechanical separation combined with a thermal treatment. Four biogas alternatives were compared to a reference slurry management scenario, notably to use the slurry as a fertilizer without prior treatment. The modelling was based on ...

A model for development of freight transport; En model for godstransportens udvikling

Patients with heterotaxy syndrome often have complex cardiac and extracardiac anomalies requiring further detailed diagnostic evaluation. They often present severe cardiac failure early in life. Newer radiological modalities in the form of spiral computed tomography (CT) and three-dimensional reconstruction of spiral CT allow clear definition of the anatomy of these anomalies. A 59-year-old woman was diagnosed with polysplenia and multiple anomalies in an abdominal ultrasonography (US) during a control medical examination due to a trivial dietary mistake. She was then referred to our institution for further examination of these anomalies and an additional thoraco-abdominal computed tomography (CT) examination. The patient was totally asymptomatic at the time of admission. There was no significant past history and no abnormal laboratory data. We performed abdominal, pelvic and thoracic CT examinations using Somatom Siemens Emotion scanner. Non-enhanced sections were ...

Serum Osteocalcin/Bone-Specific Alkaline Phosphatase Ratio Is a Predictor for the Presence of Vertebral Fractures in Men with Type 2 Diabetes

This report describes the results of a large project conducted in a corporation between Statistics Denmark and the Danish National Environmental Research Institute. The main objective of the project has been to analyse the possibilities of prescribing the development in the Danish freight transport in a more appropriate and precise way than it is done by existing models. A secondary objective of the project was to develop a model based on the findings of the analysis. The intention was to be able to describe all areas of freight transport. The analysis has proven it impossible to improve the existing calculations in some areas of transport. Hence, the project has been narrowed down to focus exclusively on road freight transport. The developed model distinguishes itself from existing models by a much higher level of detail in the calculations. This enables the model to describe the structural relations between transport and economic activity, ...

We examined whether or not BMD or bone markers were useful for assessing the risk of vertebral fractures in 248 Japanese men with type 2 diabetes. We analyzed the relationships between bone markers (osteocalcin [OC], bone-specific alkaline phosphatase [BAP], urinary N-terminal cross-linked telopeptide of type-I collagen) or BMD and HbA1c, urinary C-peptide, insulin-like growth factor-I (IGF-I), parathyroid hormone, 1,25(OH)2 vitamin D, and the presence of prevalent vertebral fractures. Multiple regression analysis adjusted for age, body height, weight, duration of diabetes, and serum creatinine showed that serum OC and OC/BAP ratio were correlated negatively with HbA1c (P?P?P?

Investigation of cardio-vascular reflex in atomic bomb survivors, (2)

Estimation of frequency, population doses and stochastic risks in brachytherapy in Japan, 1983

Electrographic R-R interval variation was examined in a total of 915 A-bomb survivors exposed at {<=}2,000 m from the hypocenter (the {<=} 2,000 m group) and a total of 1,162 A-bomb survivors exposed at >3,000 m or entered the city after the A-bombing (the >3,000 m group). Coefficient of variation (CV) for R-R interval variation on ECG tended to be decreased with advancing age in the >3,000 m group, irrespective of sex. Especially for men in this group, CV values were significantly lower for the age group of 45 to 54 years than the groups of 65 to 74 years and 75 to 84 years. Similar tendency was observed for CV values at deep breath. Decreased CV values tended to be associated with a decrease in glucose tolerance in both men and women of the >3,000 m group. In comparing the aforementioned CV values with those in the {<=}2,000 m group, there was no significant difference between the groups. R-R interval variation on ECG was ...

Energy expenditures in four men estimated by D_2 "1"8O method at two times. II. From once daily samples of urine or breath

Based on the replies to a questionnaire distributed throughout Japan in 1983, genetically significant dose (GSD), per Caput mean bone marrow dose (CMD), leukemogenically significant dose (LSD), malignantly significant dose (MSD), and per Caput effective dose equivalent (EDE) from using small sealed radiation sources for radiotherapy were estimated. Annual frequencies of brachytherapy were estimated to be 2.6 x 10"3 for men and 36.3 x 10"3 for women, with a total of 38.9 x 10"3. The annual frequencies of using afterloading technique were 0.3 x 10"3 for men and 18.8 x 10"3 for women, with a total of 19.1 x 10"3. The annual population doses per person were 7.9 nGy for GSD, 118 #mu#Gy for CMD, 19.3 #mu#Gy for LSD, 172 #mu#Gy for MSD, and 428 #mu#Gy for EDE. The annual collective effective dose equivalent was estimated to be 5.13 x 10"4 man Sv. (Namekawa, K.).

Copper-65-absorption by men fed intrinsically and extrinsically labeled whole wheat bread

To make the doubly labelled water method for determining energy expenditure more applicable in a free-living population, collection of a single daily urine or breath sample would have advantages compared to a 24-hr urine collection. Coward et al. reported the use of a single daily urine sample. In the previously described study, a single urine collection and a fasting morning breath sample were collected from four men during two 21-day periods (fall, F, spring, S) while maintaining their body wts. on controlled diets (20% calories from protein, 40% from fat, 60% from CHO [F]; 20% protein, 20% fat, 60% CHO [S]). Urine and breath samples were analyzed to determine disappearance rates of D and "1"8O for up to 21 days. Values were compared with metabolizable energy intake levels (EI), with or without corrections for estimated changes in body composition assessed by several methods. Preliminary evaluations suggest that the single daily urine sample values may ...

Comparison of doubly labeled water, intake-balance, and direct- and indirect-calorimetry methods for measuring energy expenditure in adult men

Six men were fed a diet composed of conventional foods with all bread as whole wheat bread. Intrinsically labeled "6"5Cu bread (containing 6.5 ppm Cu and 48 atom % "6"5Cu) was substituted for unlabeled bread for 3 days, and stools were collected for 24 days. Extrinsically labeled bread was then substituted for 3 days and another 24-day stool collection made. "6"5Cu excretion was measured by mass spectrometry. Mean Cu intake was 1.10 mg of Cu/day. Average Cu balance was /minus/0.06 /+-/ 0.08 mg/day. Average absorption of the intrinsic copper was 72.2 /+-/ 9.3% and of extrinsic Cu 64.2 /+-/ 5.8%. The ratio of extrinsic to intrinsic absorption was 0.906 /+-/ 0.164. Absorption of intrinsic and extrinsic tracers did not differ significantly (p > 0.05) by a paired t-test, and the ratio (E/I) was not significantly different from 1. Use of extrinsic Cu tracers to assess Cu absorption is supported by these results.

Breakfast meal composition influences plasma tryptophan to large neutral amino acid ratios of healthy lean young men

Energy expenditure (EE) of four adult men on a weight-maintenance diet was estimated by use of doubly labeled water, intake balance, and direct and indirect calorimetry. The doubly labeled water (2H218O) method was used to estimate free-living EE for 13 d. Metabolizable energy (ME) intake was used to estimate free-living EE for 1 wk. The subjects' 24-h EE was measured in a dual direct-indirect room calorimeter on 3 alternate days. Estimates of free-living EE as measured by ME intake and doubly labeled water indicate agreement between the two methods (mean difference +/- SEM, -1.04 +/- 0.63%). Measurements of EE with indirect and direct calorimetry are equivalent (mean difference 0.63 +/- 0.44%). The daily EE measured by doubly labeled water in these free-living adults over a 13-d period was 15.01% greater than the 24-h EE measured within the calorimeter.

“Bridge population”: sex workers or their clients? - STI prevalence and risk behaviors of clients of female sex workers in China

The effect of a carbohydrate, a 20% protein, or a carbohydrate +0.3% tryptophan TRP breakfast on plasma large neutral amino acid ratio was studied in 6 healthy men. The carbohydrate-rich meal produced shifts in plasma amino acid concentrations such that plasma TRP/LNAA ratios increased from 0.13 to 0.15 (p<0.04) and the protein meal decreased the ratio from 0.14 to 0.11 (p<0.04) after 1 hour. Addition of 0.3% TRP to the carbohydrate-rich meal increased plasma TRP/LNAA ratios more than 2-fold. The TRP containing meal was thus the only one likely to influence brain 5-HT synthesis, although the difference between the plasma TRP/LNAA ratios after carbohydrate and protein breakfasts suggests that the brain may distinguish, by synthesizing more or less 5-HT, the composition of breakfast meals.

As the HIV/AIDS epidemic and the spread of sexually transmitted infections (STIs) in China has come to the forefront of public health attention, female sex workers (FSWs) and their clients (CFSWs) are becoming increasingly important to HIV/STI prevention efforts. This secondary analysis uses data abstracted from the Chinese Health and Family Life Survey 1999-2000 to report prevalence rates of two STIs as well as sexual risk behaviors for CFSWs - men who paid for sex with FSWs in the past 12 months - in comparison with men who had not patronized FSWs. Among 1879 Chinese CFSWs who completed anonymous interviews and urine testing, 152 (6.3%, weighted) said they had paid for sex in the past 12 months and 18.8% of CFSWs (weighted) tested positive for gonorrhea. CFSWs were 10 times more likely t...

Late relapse of metastatic non-seminomatous testicular germ cell tumours

Late relapse of metastatic non-seminomatous testicular germ cell tumours

Although the majority of men presenting with non-seminomatous germ cell tumours (NSGCT) are cured, late relapse (occurring more than 2 years after obtaining a complete response to treatment) is increasingly recognized. The typical patterns of disease spread have been well-documented, but the findings at late relapse are more variable and less well-described. We discuss the phenomenon of late relapse, the characteristics of teratoma differentiated (TD), and the issue of long-term imaging surveillance of patients with NSGCT. The potential sites of late relapse of NSGCT and the associated spectrum of imaging appearances are illustrated.

Different paths: gender, immigration and political participation.

Some of the known toxic effects of lead in mammals including man are, impaired heme synthesis, anemia, nepatopathy, nephropathy, behavioral disorders and neuropathy. However, very little is known about the effect of lead on endocrine physiology. Some data are available on lead induced impairment of thyroid function in occupationally exposed men and experimental rats. As lead nitrate is largely consumed through water and food, in this study the wild rodents Funambulus pennanti were administered lead through their drinking water and their thyroid structure, radioiodine 131-I percentage uptake and protein bound iodine (PBI) level were assessed.

Cutaneous leishmaniasis associated with jungle training.

"Building on arguments made by Grasmuck and Pessar (1991), Hardy-Fanta (1993), and Hondagneu-Sotelo (1994), among others, this article makes the case for a gendered understanding of immigrant political socialization. Looking at recent Latin American immigrants to New York City, the article argues that immigrant Latino men are more likely to favor continuity in patterns of socialization and organization, and immigrant Latinas are more likely to favor change. This finding helps bridge theoretical and empirical literatures in immigration studies, applying the logic of gender-differentiated decisionmaking to the area of immigrant political socialization and behavior."

Trace element intake and status of Italian subjects living in the Gubbi area

In November 1977, 627 soldiers belonging primarily to the First Battalion, 82nd Airborne Division, stationed at Fort Bragg, were sent to the Canal Zone, Panama, for jungle warfare training. A medical surveillance program incorporating pre- and post-evaluations over a 6-month period with dermatologic examinations, questionnaires, and serologic tests was established. Ten cases of cutaneous leishmaniasis (1.6/100 men) were diagnosed by positive Leishmania culture. The demonstrated lack of sensitivity and specificity of the indirect fluorescent antibody test and the direct agglutination test render these serological methods useless as diagnostic screening methods in the early stages of this disease.

Study of osteoporosis using dual energy X-ray absorptiometry

Daily intakes of certain trace elements (Pb, Cd, Ni, Hg, and Cr) were assessed using dietary history and weighed record methods and concurrent chemical analysis (CA) of duplicate portions, along with blood levels, in a group (21 M, 23 F) of inhabitants of the Gubbio area (Belvedere, Biscina Scritto). The evaluation of only intake of trace elements was accomplished in 40 subjects (20 M, 20 F) 1 year later. In both surveys, trace element intakes were generally lower than the potential tolerable weekly intake. However, daily intakes of Pb, Cd, Ni, Hg, and Cr were higher in men compared to women in both surveys (P<0.05). In fact, intakes at the 50th percentile were greater in men by approximately 75% for Pb, 91% for Cd, 20% for Ni, 45% fo Hg, and 29% for Cr in the first survey. In the second survey, percentage differences for Pb, Cd, Ni, and Cr were about 12%, 28%, 26%, and 26%, respectively. Blood trace element levels were slightly higher in ...

Effect of dietary fatty acid intake on prospective weight change in the Heidelberg cohort of the European Prospective Investigation into Cancer and Nutrition

Dual energy X-ray absorptiometry (Hologic QDR-1000) was used to quantitatively analyze the diagnosis and prevention of osteoporosis. The peak bone mineral density (BMD) of the spine appeared in normal men in their twenties and in normal women in their thirties. There was acceleration of bone loss in the 50 to 60 year age bracket (premenopause and postmenopause) in normal women. On the contrary, the peak BMD of the femoral neck in normal men and women appeared in their twenties after which it decreased slightly with age. Comparison showed that the femoral neck BMD of normal women was lower than that of men throughout all ages. The fracture threshold, 0.756 g/cm[sup 2] for the spine, was obtained by scanning 73 females with spinal fractures, the mean BMDs for L2-L4 at the 90th percentile level were used as the fracture threshold. The fracture threshold of femoral neck fracture was the femoral proximal BMD of the 9th decile. ...

Dietary energy requirements of young adult men, determined by using the doubly labeled water method

OBJECTIVE: To evaluate the association between fatty acid (alpha-linolenic acid (ALA), EPA, DHA, palmitic, stearic, oleic, linoleic and arachidonic acids) intake and prospective weight change in the Heidelberg cohort of the European Prospective Investigation into Cancer and Nutrition. DESIGN: Prospective cohort study with mean follow-up time of 6.5 years. In a total of 9182 men and 10867 women aged 35 to 64 years, from body weight measurement at recruitment and calibrated body weight during follow-up, weight change was expressed as mean annual weight change relative to baseline weight (%/year) and categorised into four groups (weight loss, or =2.5 to or =7.5%/5 years). Energy-adjusted dietary fatty acid intake data were estimated from the FFQ completed at baseline. Multivariate linear regression models as well as multinomial logistic regression analyses (carbohydrate replacement models) were conducted. RESULTS: Stearic acid intake was linearly associated with ...

Behavioral modulation by mutilation pictures in women

The autors examined the hypothesis that current recommendations on dietary energy requirements may underestimate the total energy needs of young adult men, by measuring total energy expenditure (TEE) and resting energy expenditure (REE) in 14 weight-maintaining healthy subjects leading unrestricted lives. TEE and body composition were measured by using 2H(2)18O, and REE was measured by using indirect calorimetry. All subjects had sedentary full-time occupations and participated in strenuous leisure activities for 34 #+-# 6 (SE) min/d. TEE and REE were 14.61 #+-# 0.76 and 7.39 #+-# 0.26 MJ/d, respectively, and 202 #+-# 2 and 122 #+-# 2 kJ.kg-1.d-1. There were significant relationships between TEE and both body fat-free mass (r = 0.732, P less than 0.005) and measured REE (r = 0.568, P less than 0.05). Measured TEE:REE values were significantly higher than the recommended energy requirement (1.98 #+-# 0.09, compared with 1.55 or 1.67, P less than 0.005). These ...

Abstract in english Previous studies have shown that women are more emotionally expressive than men. It is unclear, however, if women are also more susceptible to the emotional modulation of behavior imposed by an affective stimulus. To investigate this issue, we devised a task in which female subjects performed six sequential trials of visual target detection following the presentation of emotional (mutilation and erotic) or neutral pictures (domestic utensils and objects) and compared the (more) data obtained in the present study with those described in a previous study with male subjects. The experiment consisted of three blocks of 24 pictures and each block had an approximate duration of 4 min. Our sample consisted of 36 subjects (age range: 18 to 26 years) and each subject performed all blocks. Trials following the presentation of mutilation pictures (283 ms) had significantly slower reaction times than those following neutral (270 ms) pictures. None of the ...

Nephron-sparing percutaneous ablation of a 5 cm renal cell carcinoma by superselective embolization and percutaneous RF-ablation

The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30-40 years, it is quite feasible that many plants will be able to operate in excess of their design lives, provided that nuclear power plant engineers demonstrate by analysis, trending, equipment and system upgrades, increased vigilance, testing and ageing management that the plant will operate safely. In the operation of nuclear power plants, safety should be always the prime consideration. Plant operators and regulators must always ensure that plant safety is maintained, and where possible enhanced, during a plant's operating lifetime. Nuclear power plant life management (PLiM) has gained increased attention over the past decade, and effective ageing management of systems, structures and components (SSCs) is a key element in PLiM for the safe and reliable long term operation of nuclear power ...

Temporal Patterns in Work-Related Fatalities Among Foreign-Born Workers in the US, 1992?2007

Evaluation of severe functional gastrointestinal motility disorders requires an investigation of the entire gastrointestinal tract. This should be possible with a single radionuclide imaging study. The purpose of this study was (1) to define normal values of small-bowel transit in men and women and (2) to assess a possible difference between gender or test meal, since it has been shown that women have slower gastric emptying than men, and gastric emptying of solids is slower than liquids. A standard gastric-emptying test for a solid (technetium-99m sulphur colloids, 230 Kcal) and liquid (indium-111 DTPA water) test meal was performed in 12 healthy male and 12 healthy female volunteers. After 135 min, the volunteer was place in the supine position for static imaging of the abdomen every 15 min for 6 h. Decay and crossover-corrected geometric mean gastric-emptying data were fit to a modified power exponential function to determine the 10% stomach ...

Social class, social mobility and mortality in the Netherlands, 1850-2004

British Library Electronic Table of Contents (United Kingdom)

This study uses data from a random sample of births in the Netherlands during the period 1850-1922 to examine the relationships between social class, social mobility and mortality at middle and old age. Population registers and personal cards covering the period from 1850 to 2004 for all Dutch provinces were used to reconstruct individual life histories of 14,900 births. For men we did not find an effect of the social class of origin (using two different SES-classifications) on mortality in age group 18 to 35. We also did not observe an effect of own social class on mortality after age 35. For women effects of social class of origin and social class of husband were generally absent as well. Our conclusion is that the standard ideas about the negative effects of processes of industrializati...

Sexual function in women receiving maintenance dialysis

British Library Electronic Table of Contents (United Kingdom)

Abstract While substantial attention has been paid to the issue of sexual dysfunction in men on chronic dialysis, less is known about this problem in women with end-stage renal disease. We sought to assess sexual dysfunction in women on chronic dialysis and determine whether patients discuss this problem with their providers and receive treatment. We prospectively enrolled women receiving chronic hemodialysis or peritoneal dialysis in Pittsburgh, PA. We asked patients to complete the 19-item Female Sexual Function Index (FSFI) to assess sexual function and a 5-item survey that assessed whether patients had discussed sexual dysfunction with their providers and/or received treatment for this problem in the past. We enrolled 66 patients; 59 (89%) on hemodialysis and 7 (11%) on peritoneal dial...

Sex Differences in Pain and Psychological Functioning in Persons With Limb Loss

British Library Electronic Table of Contents (United Kingdom)

Sex differences in pain are frequently reported in the literature. However, less is known about possible sex differences in the experience of pain secondary to a disability. The current study explored these issues in persons with limb loss (n = 335, 72% men) who were recruited as part of a postal survey. Participants provided ratings of phantom limb pain (PLP), residual limb pain (RLP), and general pain intensity. Participants also completed measures of pain-related interference, catastrophizing, coping, and beliefs. Results indicated that a greater proportion of males than females (86% vs 77%, respectively) reported the presence of PLP; however, this difference was no longer prominent when cause of limb loss was controlled. No sex differences were found in the presence of RLP, or in avera...

Serum gamma-glutamyltransferase is associated with arterial stiffness in healthy individuals

British Library Electronic Table of Contents (United Kingdom)

Summary Objective- Gamma-glutamyltransferase (GGT) has been reported to be useful in predicting cardiovascular disease. Arterial stiffness measured by brachial-ankle pulse wave velocity (baPWV) is not only a marker of vascular damage but a significant predictor of cardiovascular events. Gender difference has been reported in the association between GGT and baPWV. We assessed, therefore, the association between GGT and baPWV in a large population and determined whether there was gender difference. Design- This cross-sectional study was conducted at the Asan Medical Centre, Seoul, Republic of Korea. Subjects and measurements- Serum GGT, baPWV and conventional risk factors were measured in 10 988 apparently healthy subjects (7248 men, 3740 women) who participated in a routine health screening...

Role of antioxidants in the treatment of male infertility

British Library Electronic Table of Contents (United Kingdom)

Abstract Male infertility continues to be a clinical challenge of increasing significance. While male factors such as decreased semen quality are responsible for 25% of all infertility issues, the etiology of suboptimal semen quality is poorly understood. Many physiological, environmental, and genetic factors have been implicated, including oxidative stress. Oxidative stress is induced by reactive oxygen species (ROS), or free radicals, and although ROS are required for critical aspects of sperm function, excessive levels of ROS can negatively impact sperm quality. The origin of ROS generation, and the etiologies of increased ROS in men with suboptimal sperm quality have only recently been elucidated, offering multiple targets for potential therapy. Here, we present a critical review of th...

Relationship of blood lead to blood pressure in a longitudinal study of working men

Quantitative bone scintigraphy. A methodological evaluation in prostate cancer

The relationship of lead exposure to blood pressure has been examined in a longitudinal study of a cohort of 89 Boston, Massachusetts, policemen. At the baseline examination, subjects had a blood lead determination and three consecutive blood pressure measurements. Triplicate blood pressure measurements were also taken at years 3, 4, and 5. Multivariate analysis revealed that, after correction for previous systolic blood pressure, body mass index, age, and smoking, a high level of blood lead was a significant predictor of subsequent elevation of systolic pressure. Bootstrap simulations of these models provided supporting evidence for the observed associations. These data suggest that lead exposure can significantly affect systolic pressure.

Quantitative bone scintigraphy. A methodological evaluation in prostate cancer

Purpose: To evaluate a simple method for quantification of focal activity in bone scintigraphy (BS). Material and methods: The gamma camera was calibrated using a phantom. Quantitative bone scintigraphy (QBS) was performed on 11 men recently diagnosed with prostate cancer (PCa), for whom routine BS showed involvement of the skeleton. Following endocrine therapy for 4 to 8 months, a second QBS was performed. Changes in QBS values were then compared to changes in serum levels of prostate-specific antigen (PSA). Results: PSA response indicating regression of PCa was accompanied by a decrease in the QBS value in 8 of the 11 patients. The overall mean error of the QBS values was 15%. conclusion: QBS according to this method is a relatively simple procedure that might contribute to objective evaluation of therapeutic effects in skeletal metastases, although its validity must be tested in a larger clinical material.

Laparoscopic adrenal-sparing surgery: personal experience, review on technical aspects

British Library Electronic Table of Contents (United Kingdom)

Partial adrenalectomy is usually performed for the treatment of bilateral pheochromocytomas and in case of sporadic, monolateral tumors, to minimize the risk of adrenal failure, especially in younger patients. Due to the lack of consistent series, many issues such as correct surgical indications and technical aspects still need to be debated. From 2007 to 2010 we performed four unilateral partial adrenalectomies (3 aldosterone-producing adenomas and 1 cortisol-producing adenoma), and three bilateral subtotal adrenalectomies, consisting in total adrenalectomy on one side and partial adrenalectomy on the contralateral gland (3 bilateral pheochromocytomas in MEN IIa). In case of single tumor, partial adrenalectomy was carried out without adrenal vein ligation and the results were similar to t...

Human climatic comfort within enclosing walls with varying strengths of infrared radiation reflection

How Women Cope: Being a Numerical Minority in a Male-Dominated Profession

An experiment lasting a number of hours was carried out with 6 men under standardised climate chamber conditions to find out to what extent wallpaper that reflects about 65-75% in the infra-red range by comparison with normal wallpaper that reflect only 3-5% of heat, has measurable positive effects on the thermoregulation of the human body and the human sensation of temperature. The measurements of skin temperature and heat flow intensity in the deeper areas of the body and the periphery, and metabolic heat conversion measurements (indirect calorimetry) confirm that infra-red reflection of the heat irradiated from the body lead to a measurable heat recovery on the body surface with a reduction of metabolic conversion. It was proved that it is possible to reduce the average room temperature by up to 4 K whilst maintaining the same degree of thermal comfort, which corresponds to a 20% saving in heating energy.

Women who have academic careers in engineering have successfully navigated the social identity threats that prevent many other women from feeling that they belong in science, technology, engineering, and math fields. In this research, we examined what factors may be related to resilience in these academic environments. Female academics in engineering and nonengineering fields watched a fictitious conference video depicting either an unbalanced ratio of men to women or a balanced ratio. Subjective measures of identity threat were collected. Past experience with discrimination, positive experience with female role models, family support, and general social support were associated with a greater sense of belonging to or desire to participate in the conference. These variables all buffered neg...

Efficiency of a lead-containing tie for radiation protection of the thyroid gland

Efficiency of a lead-containing tie for radiation protection of the thyroid gland

During fluoroscopy the examiner is usually protected by a radiation-reducing body shield, leaving the thyroid unprotected. The fact that the thyroid is located in a region of the neck usually covered by the shirt collar led to the idea of designing a tie with lead core, providing easy and ''decorative'' reduction of the radiation dose. Sonographic examinations were carried out in 20 volunteers (10 men, 10 women) to determine the size of the gland and its coverage by such a tie. The reduction of the surface and organ dose was assessed using film dosimetry with scattered radiation, the body of the examiner being simulated by an Alderson phantom. On average 88% of the thyroid gland surface area was covered. Surface dose was reduced to 1%, and organ dose to 10% of the value without the protection tie. (Author).

Computed tomography colonography: the future of colon cancer screening

Colorectal cancer (CRC) is the most common cause of cancer death among Canadian non-smokers. Each year about 21,500 Canadians are diagnosed with CRC. Ninety percent of cases occur in people aged 50 years or older. An estimated 4,800 Canadian men and 4,100 Canadian women die each year from the disease. About 75% of all new CRC cases arise in people with no known risk factors. Computed tomography colonography (CTC), a cross-sectional imaging examination that permits complete structural examination of the colon, shows promise as a tool for CRC screening. This article reviews the rationale for CRC screening, currently recommended Canadian and American screening guidelines and screening tools, and current evidence supporting CTC as a CRC screening tool and its advantages over conventional screening methods.

Association of the polymorphism of the CAG repeat in the mitochondrial DNA polymerase gamma gene (POLG) with testicular germ-cell cancer

British Library Electronic Table of Contents (United Kingdom)

Background: A possible association between the polymorphic CAG repeat in the DNA polymerase gamma (POLG) gene and the risk of testicular germ-cell tumours (TGCT) was investigated in this study. The hypothesis was prompted by an earlier preliminary study proposing an association of the absence of the common 10-CAG-long POLG allele with testicular cancer as well as previously reported in some European populations' association with male subfertility, which is a condition carrying an increased risk of TGCT. Patients and methods: The number of CAG repeats in both POLG alleles was established in 243 patients with TGCT and in 869 controls by the analysis of the genomic DNA fragment. Results: A significantly higher proportion of men homozygous allele of other than the common 10 CAG repeats was fou...

Arterial stiffness is associated with low thigh muscle mass in middle-aged to elderly men

British Library Electronic Table of Contents (United Kingdom)

Objective: Sarcopenia of legs is an important cause of physical dysfunctions, frailty and dependence. Many predisposing and underlying mechanisms of sarcopenia, including age, sedentary life style, oxidative stress, insulin resistance, and low testosterone levels, are also known to be related to atherosclerosis, which is another leading cause of morbidity and mortality in elderly subjects. In this study, we investigated our hypothesis that sarcopenia and atherosclerosis are associated with each other to facilitate mutual abnormalities. Methods: Study was performed in apparently healthy 496 middle-aged to elderly persons recruited consecutively among the visitors to the medical check-up program, Anti-Aging Doc, in a University hospital, from March 2006 to December 2007.

Wind power - research and development. The wind turbine industry's view of the promotion of state-supported research and development

The windmill industry in Denmark is currently confronted with making a choice between competing technologies so that the role of the stimulus of state subsidies for research has lately increased in importance. The Ministry of Energy, it is claimed, must be aware of this as possibilities for making use of research results are dictated by the market and competition. The industry is not sympathetic to the idea of state research contracts with specified goals for which manufacturers must produce a technical solution. Consultancy firms should work towards solving general problems which could help the industry as a whole. Wind turbines which are cheap to produce and operate are of more interest to industry than those which are technologically advanced or of a lighter construction. It is not thought to be advantageous to concentrate the allocation of subsidies on one key project chosen by the Ministry itself, such as the current intense interest in turbine blades. Aerodynamics, noise ...

Review of wood fuel from early thinning and plantation cleaning in the Netherlands

Analytical means have been developed to predict scour and accretion in sub-sea structures. Such structures can be very large and can have a large density of piping and structural members. They introduce a blocking and a shielding in the flow at the sea bottom leading to variable velocities and turbulence in the interior of the structure. This changes the transport capacity of the flow and result in general erosion where the transport capacity is increased and in accretion where the transport capacity is decreased. In addition there may occur the so-called tunnel erosion for structures built on concrete mats or similar. This type of erosion undermines the foundation of the sub-sea structure. Analytical models are developed and programmed to analyse the above phenomena. The internal flow variations are found by means of the LICengineering shielding programme and these are coupled to the transport formulae. The methodology is unstable if the starting conditions are too far away from the ...

Parental subfecundity and risk of decreased semen quality in the male offspring: a follow-up study.

Discussions regarding the use of wood fuels for commercial energy production in the Netherlands began in the 1990's. The main reasons for using wood fuel are: the political demand for using renewable energy, the need to reduce CO_2 emissions, and the lack of markets for surplus timber. Only 10 % of the area of Holland is forested. Therefore, early thinning and cleaning are important management tools for improving growth and producing better quality timber. The energy potential from early thinning and plantation cleaning could be between 400 000 and 570 000 dry tons annually. The Netherlands has not experience in harvesting energy wood. However, through the International Energy Agency/Bioenergy Agreement, knowledge gained in other countries, especially Denmark, Sweden and Finland, is being transferred to Holland. In 1996, there have been made field tests with Danish equipment. Although there are few technical barriers to wood fuel in the Netherlands, the economics ...

Parental subfecundity and risk of decreased semen quality in the male offspring: a follow-up study

A few studies have found poor semen quality in sons whose mothers have received fertility treatment, but it is unknown whether the poor semen quality is related to the infertility treatment or to infertility per se, for example, whether it is caused by hereditable factors. Using data from a population-based, Danish follow-up study conducted in 2005-2006, the authors of the present study examined whether sons of subfertile couples who had not received fertility treatment had poorer semen quality than sons of fertile couples. Among the 311 participants, an inverse association between parental waiting time to pregnancy and both semen volume and total sperm count was observed (p trend = 0.04 and p trend = 0.046, respectively). Semen volume in sons of subfertile parents (pregnant after > or =1 years) was 19% lower in comparison with that in sons of parents whose waiting time to pregnancy was 0-6 months (p = 0.02). Additionally, sperm concentration and percentage of ...

HEALTH POLICY INTERVENTION IN SCHOOLS PROMOTE PHYSICAL ACTIVITIES AMONG THE PUPILS

This article presents the results of analyses of large-scale integration of wind power, photo voltaic (PV) and wave power into a Danish reference energy system. The possibility of integrating Renewable Energy Sources (RES) into the electricity supply is expressed in terms of the ability to avoid excess electricity production. The different sources are analysed in the range of an electricity production from 0 to 100% of the electricity demand. The excess production is found from detailed energy system analyses on the computer model EnergyPLAN. The analyses have taken into account that certain ancillary services are needed in order to secure the electricity supply system. The idea is to benefit from the different patterns in the fluctuations of different renewable sources. And the purpose is to identify optimal mixtures from a technical point of view. The optimal mixture seems to be when onshore wind power produces approximately 50% of the total electricity ...

Now, more than ever, there are serious health concerns for obese and overweight children. Schools are the perfect setting for children to learn, and this influence can play an important role in preventing children from becoming obese and overweight. The study concerns the behaviors of Health Promoting School (HPS) according to a broad definition of HPS in World Health Organization (WHO), or dependent on schools own health promoting policies. The purpose of study research is to examine whether promoting physical activity among the children at schools in relation to a school health policy such as Food and Nutrition Policy (FNP). This was determined through the comparisons between the FNP based schools and non policy based schools. The study undertook surveys among school food coordinators in the selected Danish primary schools through a web-based questionnaire. The questions in the survey were more focused on physical activity in internal and external school ...

The background for this paper is a growing interest during the past decade in Denmark in the concepts of ?situated learning?, ?social theory of learning? and ?learning in communities of practice? developed by the American social anthropologist Jean Lave and the Californian Research Scientist Etienne Wenger. The work by Jean Lave from 1988 (Lave, 1988) based on anthropological field studies in Brazil and Liberia as well as later works by Lave & Wenger (Lave and Wenger, 1991; Chaiklin and Lave, 1993; Wenger, 1998; Wenger, McDermott, R. and W. Snyder, 2002) on situated learning and social learning theory have provoked considerable response in anthropological studies, in learning theories as well asin considerations about practical implementation of concepts like ?lifelong learning? in Denmark in recent decades. The European concept of ?lifelong learning? has had a big impact on educational thinking, including teacher education. In addition to this, IT has been playing a continuously ...

Validation and reliability of the Baecke questionnaire for the evaluation of habitual physical activity in adult men

There was a total bus strike in the Danish town of Esbjerg during the spring of 1995. It lasted for a very long period of time and was extremely disruptive. After this the number of bus passengers fell dramatically. As a result, a group of researchers in this field, employed at Aalborg University initiated an investigation of how former bus passengers solved their personal transport problems without the help of a bus service. Telephone interviews were carried out and 1485 persons agreed to take part in the investigation. The data collected in this way are presented in the paper and give information on the number of people who owned cars, how often members of a family availed themselves of bus transport, age groups, the alternative means of transport used generally or for conveyance to the place of work or school, amount of extra, or less, travel time, travel expenses, and other irritations experienced in connection with the strike. It is concluded that the ...

Abstract in english The aim of this study was to verify validity and reliability of the scores for physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS) of the Baecke habitual physical activity questionnaire in adult males. Twenty-one students of Physical Education were evaluated. For validation, the maximum oxygen uptake (O2max) and the decrease of the heart rate in percentile (%DH (more) R) were measured through the Cooper's 12-minute walk or run test, and an annual index of physical exercise (IPE), and a week index of locomotion activities (ILA). The reliability was verified through test-retest with interval of 45 days. The Pearson correlation coefficient, and partial correlation adjusted for age and body mass index were used for validation. The intraclass correlation and paired t-test were used for reliability. The results indicated that %DHR was correlated with LLA and TS (r = 0.47 and p = 0.030; r = 0.48 and p = 0.027, respectively). ...

Methionine kinetics in adult men: effects of dietary betaine on L-[2H3-methyl-1-13C]methionine

Background. Through PSA screening the rate of prostate cancers detected at an early stage has increased significantly; thus a decrease in mortality can be expected in the near future. Despite all scientific efforts, however, the molecular mechanisms underlying the development and progression of prostate cancer remain poorly understood. Prostate cancer is a disease of aging men and epidemiological evidence supports a major contribution to its development through diet, lifestyle and environmental factors. Genetic instability is the basic phenomenon of tissue cell cancerisation. This instability can be hereditary or due to mutations and other chromosomal aberrations acquired during life. In recent years a large number of interesting data have been collected which show the relationships between focal atrophy and genetic instability of the prostate epithelia. Atrophy can be the result of prostatitis, ischemia as well as of oxidative stress (diet). Several chromosomal ...

Methionine kinetics and balance at the 1985 FAO/WHO/UNU intake requirement in adult men studied with L-[2H3-methyl-1-13C]methionine as a tracer

The effects of a daily 3-g supplement of betaine on kinetic aspects of L-[2H3-methyl-1-13C]methionine (MET) metabolism in healthy young adult men were explored. Four groups of four subjects each were given a control diet, based on an L-amino acid mixture supplying 29.5 and 21.9 mg.kg-1.d-1 of L-methionine and L-cystine for 4 d before the tracer study, conducted on day 5 during the fed state. Two groups received the control diet and two groups received the betaine supplement. Tracer was given intravenously (iv) or orally. The transmethylation rate of MET (TM), homocysteine remethylation (RM), and oxidation of methionine were estimated from plasma methionine labeling and 13C enrichment of expired air. RM tended to increase (P = 0.14) but the TM and methionine oxidation were significantly (P less than 0.05) higher after betaine supplementation when estimated with the oral tracer. No differences were detected with the intravenous tracer. Methionine concentration in ...

Feasibility of ultra-low-dose multislice CT colonography for the detection of colorectal lesions: preliminary experience

The upper range of the requirement for methionine plus cystine in healthy adults was proposed in 1985 by FAO/WHO/UNU to be 13 mg.kg body wt-1.d-1. To explore the validity of this estimate, five healthy, young adult men were given for 7 d a diet based on an L-amino acid mixture supplying 13 mg methionine.kg-1.d-1 (87 mumol.kg-1.d-1) without cystine. Constant intravenous infusions of L-[2H3-methyl-1-13C]methionine were given on days 5 and 7 while subjects were in the fed and postabsorptive states, respectively. Estimates were made of methionine oxidation, and daily methionine balance was derived from the intake-oxidation data. For the five subjects, methionine balances were -0.9, +0.7, +3.5, -3.1, and -3.8 mg kg-1.d-1, or -6, +5, +23, -21, and -26 mumol.kg-1.d-1. These findings lead to the conclusion that the upper range of the requirement for methionine plus cystine probably exceeds 13 mg.kg-1.d-1 in healthy young adults. The implications of this conclusion for ...

Assessment of chromosomal abnormalities in sperm of infertile men using sperm karyotyping and multicolour fluorescence in situ hybridization (FISH)

Our objective was to evaluate the feasibility of ultra-low-dose scanning for multislice CT colonography in the detection of colorectal lesions. Twenty-seven patients (14 men, 13 women) with clinical indication for conventional colonoscopy were recruited. Multislice spiral CT (Somatom Plus 4 Volume Zoom, Siemens, Germany) examinations were performed after standard oral colonoscopic preparation and colonic distension with room air. Images were acquired using 2.5-mm collimation, 3.0-mm slice thickness, standard reconstruction kernel, 140 kVp, and 10 mAs. Supine and prone acquisitions were obtained in all patients. Images were analyzed on a workstation by two gastrointestinal radiologists. Conventional colonoscopy was performed on the same day in all patients and represented the standard of reference. Total radiation exposure was also calculated. All colorectal cancers were correctly identified at CT colonography (9 of 9, sensitivity 100%). The CT colonography also ...

Accumulation and excretion of metabolized "1"0"6Ru in prawn meat ingested by mice

Individuals with male factor infertility resulting from idiopathic oligo-, astheno- or teratozoospermia are frequently offered IVF in an attempt to increase their chances of having a child. A concern remains whether these infertile males have an elevated risk of transmitting chromosomal abnormalities to their offspring. Sperm chromosomal complements from these men were assayed using the human sperm/hamster oocyte fusion system and fluorescence in situ hybridization (FISH) on sperm nuclei. For each of 5 infertile patients, 100 sperm karyotypes were analyzed and multicolour FISH analysis was performed on a minimum of 10,000 sperm nuclei for each chromosome-specific DNA probe for chromosomes 1 (pUC1.77), 12 (D12Z3), X (XC) and Y (DYZ3). As a group, the infertile patients showed increased frequencies of both numerical ({chi}{sup 2}=17.26, {proportional_to} <0.001) and total abnormalities ({chi}{sup 2}=7.78, {proportional_to} <0.01) relative to control donors when ...

[Urinary infection in geriatric short stay: value of urinary strips].

This paper aims at the study of the transfer and accumulation of "1"0"6Ru from marine foods to man through the grazing food chain and evaluation of the radiation exposure to man. As a model, accumulation and excretion of "1"0"6Ru in mice orally administered by the meat of prawn (Penaeus japonicus) which accumulated the radionuclide from the sea water, were examined and compared with those in mice administered by non-radioactive prawn meat mixed with the contaminant in inorganic chemical forms (the control diet); on the latter experiment, the previous evaluation method of the radiation exposure was based. Higher concentrations of "1"0"6Ru in tissues and organs of mice were observed in the former diet than in the latter because of the higher absorption rate of "1"0"6Ru from the gastrointestinal tract (17.4 +- 4.4%, the control diet: 0.7 +- 0.7%) and smaller excretion. As the results of this experiment, the critical organs for men by ingestion of such a meat should be ...

Virtual colonoscopy (CT colonography) in the identification of colorectal cancer. A prospective study in symptomatic patients

The blinded study of CBUE (cytobacteriological urine examination) test strips was carried out in 100 patients (65 women, 35 men), mean age 85.52 +/- 6.28 years, admitted for a short stay in a geriatrics department. Urinary infection was present in 19% of the cases. Typical clinical signs (pollakiuria, dysuria, hematuria, burning upon voiding) were rare, less than 10%. General signs, such as deterioration of general status (65% of the cases) and loss of autonomy (53% of the cases), on the other hand, were predominant and their relatively unspecific nature required a reliable screening test for urinary infection. Good results of sensitivity (89.5%), specificity (98.7%), and the leukocytes/nitrites values, confirmed the validity of the urine test strip in hospitalized elderly patients. In addition, the negative predictive value of the combination leukocytes and nitrites (90.8%) would have prevented 71 samples from being sent to the laboratory for CBUE, resulting in an ...

Usefulness of thromboaspiration with Desilets-Hoffman sheath in thrombosed hemodialysis access graft

Aim of this study was to evaluate the sensitivity of virtual colonoscopy (CT colonography) in the identification of colorectal cancer and to define the limitations and the advantages of this imaging modality, as well as indications to the examination. It was examined prospectively 62 symptomatic patients aged 36 to 82 years (28 women and 34 men). All patients underwent both conventional and virtual colonoscopy on the same day; the conventional examination allowed exploration of the entire colon. Conventional colonoscopy identified 89 lesions 3-50 mm in diameter, namely 84 benign and 5 malignant lesions. No lesions were identified in 12 patients. CT colonography identified 52 of the 89 lesions, with 57.1% diagnostic accuracy. They were 11 false positives (82.5% positive predictive value and 52.2% specificity) and 37 false negatives (24.5% negative predictive value and 58.4% sensitivity). Sensitivity was significantly higher (85.7%) for polyps #>=# 1 cm. Virtual ...

The prevalence, management and outcome for acute wounds identified in a wound care survey within one English health care district

British Library Electronic Table of Contents (United Kingdom)

This paper reports the characteristics and local management of 826 acute wounds identified during an audit across all health care providers serving the population of Bradford, UK. Of the wounds encountered 303 were traumatic wounds and 237 primary closures with smaller numbers of other acute wound types. Of the 303 traumatic wounds 174 occurred in women (57.4%). Men predominated in the under 45s (65M:26F), this being largely accounted for by hand and finger trauma (n=62) particularly in patients of working age (M32:F12). Women predominated in the over 65s (50M:130F), this being largely accounted for by lower limb traumatic wounds (M24:F91), the majority of these being in patients 65 and over (M14:F82). In this sub-group of 96 patients 25 had wounds of 6 weeks or longer duration, only 3 had...

Selegiline Transdermal System (STS) as an Aid for Smoking Cessation.

In this paper the authors describe the ways poststructuralist discourses assisted us to reading and reflection on data collected as part of a traditional survey-style research study. The study--generated in response to widespread concern about falling male enrolment rates at the authors' regional university--focused upon factors affecting rural male school-leavers' decisions about postschool destinations, and upon these students' attitudes to higher education. In the paper that follows, the authors contest the dominant discourses that are frequently drawn on to explain differences in male and female higher education enrolment trends. They then focus upon the features of two of the more dominant stories that students told to explain this 'difference': stories about 'real men', and stories about the value of the 'practical' over the 'theoretical'. In addition, they present another story that draws upon girls' views of higher education. Together, these stories ...

Repeated quantitative bone scintigraphy in patients with prostatic carcinoma treated with orchiectomy

INTRODUCTION: This study examined the efficacy and safety of selegiline transdermal system (STS) and brief repeated behavioral intervention (BRBI) for smoking cessation in heavy smokers. We hypothesized that the quit rate of subjects who received STS and BRBI would be significantly greater than that of those who received placebo patch and BRBI. METHODS: This was a double-blind, placebo-controlled parallel-group study in which 246 men and women were randomized to receive either STS (n = 121) or placebo patch (n =125) for 9 weeks. Recruitment targeted heavy smokers, defined as individuals with self-reported use of ?15 cigarettes/day in the 30 days prior to enrollment, who had smoked cigarettes for the past 5 years, and had an expired CO level ?9 ppm during screening. RESULTS: Although STS was well tolerated, the overall results indicated that STS with BRBI was not more effective than placebo plus BRBI for smoking cessation (p = .58). Conclusions: The results are ...

Repeated quantitative bone scintigraphy in patients with prostatic carcinoma treated with orchiectomy

Bone scintigraphy was performed in 16 men with newly diagnosed prostatic carcinoma before orchiectomy as well as 2 weeks and 2 months after operation. The uptake in the lower thoracic and lumbar vertebrae was registered up to 240 min after injection of /sup 99m/Tc-MDP and was then calculated for each patient and vertebra. The relative standard deviation in measured uptake due to measuring technique was estimated to be +-7%. In eight patients, who had normal bone scintigraphies before orchiectomy, there were no changes in the uptake values after operation. The remaining eight patients had widespread metastatic involvement prior to treatment, six of these patients showed a so-called 'flare phenomenon' in the abnormal vertebrae which means an initial increase in uptake after operation followed by a decreased uptake in response to therapy. One patient had a continuously increased uptake in all the abnormal vertebrae which correlated well with the ...

Potential exposure of workers to phosphide was examined during an in-depth industrial hygiene survey at the Bunge Corporation, in Kansas City, Kansas, where the gas was used as a grain fumigant. During the study, 14 men were employed at the facility. Tablets of aluminum phosphide were added to the grain mass for fumigation. General dilution ventilation resulted from outside air entering the work areas through ventilation louvers; there was also a local-exhaust ventilation system. Air samples revealed that, when the fumigant dispensers were being filled, workers in the area had significant exposure. At the time of the survey the relative humidity in the facility was high, permitting the reaction to phosphide to occur more readily. The levels of phosphide and respirable dust were reasonably low in the elevators, suggesting that the ventilation system was adequate. The author recommends that workers filling the dispenser with the aluminum phosphide be required to wear ...

Function-preserving surgery for rectal cancer

Annual medical examinations are conducted by Brookhaven National Laboratory (BNL) for a population of Marshallese who were accidentally exposed to radioactive fallout in 1954, for a comparison population, and for all inhabitants of the atolls of Rongelap and Utirik. Disease surveillance includes analysis of serum samples. Elevated serum uric acid (SUA) levels are common along Pacific populations, and modifying environmental factors have been investigated as a cause for this finding. The authors have studied SUA levels of people living in the Marshall Islands, and have found elevated values similar to those reported for other Micronesian populations. The nearly Gaussian distribution of individual serum uric acid values for men, and for women less than or equal to45 years of age, indicates that the elevation is due to a regularized increase in serum uric acid rather than to a subpopulation that has pathologic hyperuricemia. The higher serum uric acid levels appear, ...

Epidemiologic studies of coronary heart disease and stroke in Japanese men living in Japan, Hawaii, and California: demographic, physical, dietary, and biochemical characteristics

When total mesorectal excision (TME) is accurately performed, dysfunction, theoretically, does not occur. However, there are differences among individuals in the running patterns and the volumes of nerve fibers, and if obesity or a narrow pelvis is present, nerve identification is difficult. Currently, the rate of urinary dysfunction after rectal surgery ranges from 33% to 70%. Many factors other than nerve preservation play a role in minor incontinence. Male sexual function shows impotence rates ranging from 20% to 46%, while 20%-60% of potent patients are unable to ejaculate. In women, information on sexual function is not easily obtained, and there are more unknown aspects than in men. As urinary, sexual, and defecation dysfunction due to adjuvant radiotherapy have been reported to occur at a high frequency, the creation of a protocol that enables analysis of long-term functional outcome will be essential for future clinical trials. In the treatment of rectal ...

Do gender and torus mandibularis affect mandibular cortical index? A cross-sectional study

These summary descriptive data of ethnically similar cohorts of indigenous and migrant Japanese males have shown similarities or slight differences in characteristics wholly or largely genetically determined, such as blood groups, stature, and skeletal size. Differences have been noted in characteristics largely environmental or behavioral, such as diet and cigarette smoking habit, as well as in characteristics determined by a varying mixture of genetic and environmental influences, such as weight, blood pressure, glucose tolerance, and serum lipid and uric acid levels. Detailed analyses of the distributions of laboratory variables, of dietary data obtained by different methods, and of correlations among laboratory, dietary, physical, and demographic variables are currently in progress. Also part of the study plan are determinations of disease prevalence from evaluation of examination, laboratory, and electrocardiographic findings, of disease incidence from repeat examinations and from ...

Cancer mortality among French atomic energy commission workers

Citrate is an important naturally occurring inhibitor of calcium stone formation in urine. Urinary citrate excretion was examined in 43 consecutive patients with recurrent idiopathic calcium nephrolithiasis and in 50 normal controls by a specific enzymatic technique. Hypocitraturia (<1.6 mmol/24h) was found in 14 (33%) stone formers compared to 6 (12%) normal controls (p = 0.03). Citrate excretion expressed as citrate-creatinine ratio in 24 hour urine samples was significantly lower in the stone formers than in the healthy controls (p = 0.03), and significantly lower in healthy men, compared to healthy females (p = 0.006). There was a great variability in urinary citrate levels in both groups, and a considerable overlap in the urinary citrate excretion between normal subjects and stone formers. Factors other than urinary citrate excretion must therefore be of importance in the pathophysiology of calcium stone formation. Citrate-calcium ratio in urine proved to ...

Breakdowns of high-voltage transmission lines due to sea-salt deposits on insulators

An analysis of the mortality of workers employed at the Commissariat a l'Energie Atomique (CEA) between 1946 and 1994 is presented. Standardized Mortality Ratios (SMR) are computed with reference to the French national population for the period 1968-1994. 51 286 workers are included in the study. 3 784 deaths occurred between 1968 and 1994. A healthy worker effect is observed for men (SMR=0.53 Cl{sub 90%}=[0.52; 0.55]) and for women (SMR=0.70 Cl{sub 90%}=[0.64; 0.76]). An excess is observed for male pleural cancers (SMR=1.54, Cl{sub 90%}=[1.03; 2.21]). An excess of breast cancer is observed among women, statistically significant for the 1980-1994 period (SMR=1.30, Cl{sub 90%}=[1.04; 1.61]). An excess is observed for malignant melanoma for both sexes (SMR=1.38, Cl{sub 90%}=[0.95; 1.96]), stronger for the 1990-1994 period (SMR=2.11, Cl{sub 90%}=[1.25; 3.34]). It diminishes with age.

Breakdowns of high-voltage transmission lines due to sea-salt deposits on insulators

Until 1990, in Tuscany, salt pollution of anti-salt insulators installed on high-tension transmission lines had led to rare breakdowns. On the contrary, in the last months of 1990, in most of Tuscany, following a strong libeccio wind coming from the Tyrrhenian Sea, and due to a long period of drought, salt deposits accumulated on the insulators of the high-voltage transmission lines (380 kV, 220 kV and 132 kV). This phenomenon not only took place in the coastal areas near Livorno, Pisa and Grosseto, but also in areas far away from the sea such as Florence, Prato, Arezzo and Siena. Following this, several high-tension lines, and whole sections of 380 kV electric stations went out of order, damaging the stations' equipment, insulators on the lines, and in particular porcelain insulators. The maintenance operations that were immediately undertaken consisted in washing operations, first focussed on stations, and then on lines. Several hundred men and some ...

A prospective study of 100 roboticallyassisted laparoscopic adrenalectomies

Direct radionuclide cystography is known to be sensitive and safe in children with suspected vesical-ureteral reflux. In this study we have investigated the utility of direct radionuclide cystography in renal transplant recipients with a recent history of pyelonephritis or recurrent urinary infections. Direct radionuclide cystography is a simple test, however it requires a rigorous methodology in order to obtain images during fill-in as well as during voiding in both men and women. The images must be interpreted using a rigorous image display methodology. Twenty-eight radionuclide cystographies were performed in 17 patients. Among the 17 tests performed for the initial diagnosis of reflux , 12 were positive. Four patients with positive results and four patients with negative results were also investigated by radiologic cystography. Similar results were obtained in those patients. Nine scintigraphies were done after treatment by surgery or teflon injection ; six of ...

Radioactivity of people in Finland after the Chernobyl accident in 1986

It has been previously stated that the minimum physiological recommendations for the indispensable amino acids in health adults, as proposed by FAO/WHO/UNU in 1985, are far too low, except for the methionine. An amino acid stable isotopic kinetic study was conducted to seek further experimental support to this hypothesis. Twenty healthy young men received an l-amino acid based diet, supplying 140 mg N.kg"-"1.d"-"1, patterned on egg protein for 1 week, then for 3 weeks either i) a pattern based on current international recommendations (FAO diet, n=7), ii) a the tentative Laboratory of Human Nutrition of the Massachusetts Institute of Technology, new amino acid recommendation pattern (MIT diet, n=7) or iii) again the egg hen pattern (EGG diet, n=6). All subjects were again studied for one final, consecutive week of the egg diet. At the end of the initial week, at the first and third week with the three experimental diets,and after three days following the return of ...

Scale-up of two-phase flow in heterogeneous chalk. Matrix properties

After the reactor accident at Chernobyl on April 26, 1986 radioactive fallout was carried by air currents to most parts of Europe. The radioactive air currents reached Finland on April 27. Immediately after the arrival of such air in Finland, contamination of people by radioactive nuclides began via inhalation of this air. The ingestion route become important later, when radionuclides were transported via different foodchains to man. To determine the level of radionuclides in the body and to estimate the internal radiation doses caused by the Chernobyl accident, whole-body counting measurements were performed. The results of whole-body counting of six different groups of Finnish people measured during 1986 after the accident at Chernobyl are reported. Three were reference groups measured routinely once or twice annually, two groups were comprised of workers at nuclear power stations and one group consisted of 262 persons not belonging to any other group. The total number of whole-body ...

Treatment of malignant gastroduodenal obstruction with using a newly designed complex expandable nitinol stent: initial experiences

This investigation presents scale-up of a detailed heterogeneous geostatistical model to a full field reservoir simulation model, considering both single and two-phase flow properties. The model represents a typical low permeability Danish North Sea chalk reservoir and includes capillary pressure and saturation end-point variations. Two new up-scaling methods has been investigated, all based on fine scale simulation on a cross section of the geomodel. The first methods assumes piston style behaviour and a coupled viscosity is introduced into the basic Darcy`s equations. The second method is a modification of the JBN method traditionally applied in analysing results from core flooding experiments, which emerged as the most successful and therefore also the recommended method. 1. In addition to the up scaling work we review the Equivalent Radius Method for capillary pressure normalisation with explicit derivation of type functions for Maastrichtian and Danian chalk ...

Transarterial Chemoembolization (TACE) for Inoperable Intrahepatic Cholangiocarcinoma

We wanted to evaluate the usefulness of a new type of a complex expandable nitinol stent that was designed to reduce the stent's propensity to migration during the treatment of malignant gastroduodenal obstructions. Two types of expandable nitinol stent were constructed by weaving a single thread of 0.2mm nitinol wire in a tubular configuration: an uncovered stent 18mm in diameter and a covered stent 16mm in diameter. Both ends of the covered stent were fabricated by coaxially inserting the covered stent into the tubular uncovered stent and then attaching the two stents together with using nylon monofilament. Under fluoroscopic guidance, the stent was placed in 29 consecutive patients (20 men and 9 women, mean age: 65 years) who were suffering with malignant gastric outlet obstruction (n=20), duodenal obstruction (n=6) or combined obstruction (n=3). Clinical improvement was assessed by comparing the food intake capacity before and after the procedure. The ...

The results of radical retropubic prostatectomy and adjuvant therapy for pathologic stage C prostate cancer

The aim of this retrospective study was to determine the safety and efficacy of chemoembolization (TACE) as palliative treatment for patients with unresectable intrahepatic cholangiocarcinoma (CCA) and to compare the results with those in the literature. Fifteen patients with histology-proven CCA (5 men, 10 women) had received palliative treatment with TACE over a 6-year period. The treatment protocol comprised repeated TACE at a minimum of 8-week intervals. TACE was performed with a mixture of 10 ml Lipiodol and 10 mg mitomycin C injected into the tumor-supplying vessels. Follow-up investigations after 8-10 weeks comprised contrast-enhanced multislice spiral CT and laboratory control. Statistical evaluation included survival analysis using the Kaplan-Meier method. During the investigation period 58 TACEs (3.9 #+-# 3.8; 1-15) were performed in 15 patients. Mean tumor size was 10.8 #+-# 4.6 cm (range, 2.0-18.0 cm). Unifocal tumor disease was diagnosed in eight ...

The radiological accident in Tammiku

Purpose: The results of therapy in 288 men with pathologic Stage C prostate cancer who underwent radical retropubic prostatectomy (RRP) were analyzed to determine the effects of adjuvant therapy. Methods and Materials: Twenty-seven of the 288 patients received preoperative neoadjuvant hormonal therapy (leuprolide acetate). Postoperatively, 60 patients received adjuvant radiotherapy (RT) to the prostate bed. Follow-up ranged from 3 to 83 months (median = 32 months). Freedom from failure (FFF) was defined as maintaining a serum PSA level of #<=# 0.3 ng/ml. Results: The FFF was 61% at 3 years and 45% at 5 years for the entire group. The FFF following RRP plus RT was 75% at 3 years and 57% at 5 years as compared to 56% at 3 years and 40% at 5 years for RRP without RT (p = 0.049). The FFF following RRP plus neoadjuvant hormonal therapy was 58% at 3 years and 40% at 5 years as compared to 60% at 3 years and 45% at 5 years following RRP without hormonal therapy (p = ...

The Results of Postoperative Radiation Therapy for Perihilar Cholangiocarcinoma

On 21 October 1994, three brothers entered a waste repository at Tammiku, Estonia, without authorization and removed a metal container enclosing a caesium-137 source. During the removal the source was dislodged and fell to the ground. One of the men picked up the source, placed it in his pocket and took it to his home in the nearby village of Kiisa. Very soon after entry into the repository he began to feel ill, and few hours later he began to vomit. The man was subsequently admitted to hospital with severe injuries to his leg and hip and died on 2 November 1994. The injury and subsequent death were not attributed to radiation exposure, and the source remained in the man's house with his wife and stepson and the boy's great-grandmother. The boy was hospitalized on 17 November with severe burns on his hands, and these were identified by a doctor as radiation induced. The authorities were alerted, and the Estonian Rescue Board recovered the source from the house. The ...

Reliability of indices of neuromuscular leg performance in end-stage renal failure.

The aim of this study was to evaluate the results of postoperative radiotherapy in a case of perihilar cholagiocarcinoma by analyzing overall survival rate, patterns of failure, prognostic factors for overall survival, and toxicity. Between January 1998 and March 2008, 38 patients with perihilar cholangiocarcinoma underwent a surgical resection and adjuvant radiotherapy. The median patient age was 59 years (range, 28 to 72 years), which included 23 men and 15 women. The extent of surgery was complete resection in 9 patients, microscopically positive margins in 25 patients, and a subtotal resection in 4 patients. The tumor bed and regional lymphatics initially received 45 Gy or 50 Gy, but was subsequently boosted to a total dose of 59.4 Gy or 60 Gy in incompletely resected patients. The median radiotherapy dose was 59.4 Gy. Concurrent chemotherapy was administered in 30 patients. The median follow-up period was 14 months (range, 6 to 45 months). The 3-year overall ...

Radiologic findings of extraosseous Ewing's sarcoma

The purpose of this study was to examine the day-to-day reproducibility and single measurement reliability of peak force, time to half peak force and rate of force development indices of knee extension neuromuscular performance in patients with end-stage renal failure. Eleven self-selected patients (6 men, 5 women) receiving maintenance dialysis (dialysis history 67 +/- 42.8 month) completed 3 inter-day assessment sessions. Each comprised a standardized warm-up and 3 intermittent static maximal voluntary actions of the knee extensors of the preferred limb (45 degrees knee flexion angle [0 degrees = full knee extension]) using a specially-constructed dynamometer. Repeated measures ANOVA of coefficient of variation scores revealed significant differences between indices in their reproducibility across day-to-day trials. Post-hoc comparisons of group mean scores suggested that peak force (6.6 +/- 3.0%) offers significantly greater measurement reproducibility than time ...

Radiofrequency Ablation of Intrahepatic Cholangiocarcinoma: Preliminary Experience

The purpose of this study is to evaluate the radiologic findings of the extraosseous Ewing's sarcoma. Six patients with pathologically confirmed extraosseous Ewing's sarcoma were retrospectively reviewed. Patients included two men and four women with an average age of 21.5 years (age range 9-48 years). Plain radiographs (six patients), magnetic resonance (MR) images (five patients), computed tomographic (CT) scans (three patients) and whole body scintigraphy (two patients) were reviewed and analyzed. Images were evaluated with regard to lesion location, size, margin, muscle or bone involvement and intrinsic imaging characteristics on CT and MRI. The tumors were located in the thigh (three patients), back (two patients) and upper arm (one patient). The tumors ranged in size from 2.3 cm to 7.5 cm (mean, 5.2 cm), were mainly well circumscribed and showed no evidence of calcification prior to treatment. Margins were well defined in four out of the six patients. Four ...

Prospective evaluation of femoral head viability following femoral neck fracture

The purpose of this study was to evaluate the safety and efficacy of percutaneous ultrasound (US)-guided radiofrequency ablation (RFA) in patients with intrahepatic cholangiocarcinoma (ICCA) in a small, nonrandomized series. From February 2004 to July 2008, six patients (four men and two women; mean age 69.8 years [range 48 to 83]) with ICCA underwent percutaneous US-guided RFA. Preintervetional transarterial embolization was performed in two cases to decrease heat dispersion during RFA in order to increase the area of ablation. The efficacy of RFA was evaluated using contrast-enhanced dynamic computed tomography (CT) 1 month after treatment and then every 3 months thereafter. Nine RFA sessions were performed for six solid hepatic tumors in six patients. The duration of follow-up ranged from 13 to 21 months (mean 17.5). Posttreatment CT showed total necrosis in four of six tumors after one or two RFA sessions. Residual tumor was observed in two patients with larger ...

Phase I Study of Conformal Radiotherapy and Concurrent Full-Dose Gemcitabine with Erlotinib for Unresected Pancreatic Cancer.

The bone scans of 33 patients (pts) with recent subcapital fractures (fx) of the femur were evaluated prospectively to determine their value in predicting femoral head visability. Each of the 33 pts (ll men, 22 women, age range 30-92) had a pre-operative bone scan within 72 hrs of the fx (23 pts within 24 hrs). Anterior and posterior planar views of both hips and pinhole views (50% of pts) were obtained 2 hrs after administration of Tc-99m HDP. The femoral head was classified as perfused if it showed the same activity as the opposite normal side or if it showed only slightly decreased activity. Femoral heads showing absent activity were classified as nonperfused. Overall, 20 of the 33 pts showed a photopenic femoral head on the side of the fx. Only 2 pts showed increased activity at hte site of the fx. Internal fixation of the fx was performed in 23 pts, 12 of whom had one or more follow-up scans. Five of these 12 pts showed absent femoral head activity on their ...

Pathological study on autopsy cases at Hiroshima Atomic Bomb Hospital, September 1956 - March 1988

PURPOSE: To determine the recommended dose of radiotherapy when combined with full-dose gemcitabine and erlotinib for unresected pancreas cancer. METHODS AND MATERIALS: Patients with unresected pancreatic cancer (Zubrod performance status 0-2) were eligible for the present study. Gemcitabine was given weekly for 7 weeks (1,000 mg/m(2)) with erlotinib daily for 8 weeks (100 mg). A final toxicity assessment was performed in Week 9. Radiotherapy (starting at 30 Gy in 2-Gy fractions, 5 d/wk) was given to the gross tumor plus a 1-cm margin starting with the first dose of gemcitabine. A standard 3 plus 3 dose escalation (an additional 4 Gy within 2 days for each dose level) was used, except for the starting dose level, which was scheduled to contain 6 patients. In general, Grade 3 or greater gastrointestinal toxicity was considered a dose-limiting toxicity, except for Grade 3 anorexia or Grade 3 fatigue alone. RESULTS: A total of 20 patients were treated (10 men and 10 ...

Nonlinear analysis and prediction of pulsatile hormone secretion

A retrospective review was made of 2,659 autopsy patients obtained during the past 31 years and a half in Hiroshima Atomic Bomb Hospital. Of the patients, 1,328 (49.9%) were A-bomb survivors. Five hundred and six A-bomb survivors (38.1%) had been exposed at up to 2,000 m from the hypocenter. There was no correlation between the incidence of malignancy and the presence of exposure to A-bombing. The incidence of multiple malignancy was slightly higher in A-bomb survivors exposed at the place nearer the hypocenter. In the group of A-bomb survivors, cancer of the lung was the most common for men; and cancer of the stomach was the most common for women. The incidence of malignancy has been high in the exposed group during the early eras of examination; however, this figure has recently become high in the non-exposed group. Regarding the kinds of malignancy, there was no significant difference between the exposed and non-exposed groups. The incidence of leukemia was high ...

Minerals and trace elements determination in diets by neutron activation analysis

Pulsatile hormone secretion is observed in almost every hormonal system. The frequency of episodic hormone release ranges from approximately 10 to 100 pulses in 24 hours. This temporal mode of secretion is an important feature of intercellular information transfer in addition to a dose-response dependent regulation. It has been demonstrated in a number of experiments that changes in the temporal pattern of pulsatile hormone secretion specifically regulate cellular and organ function and structure. Recent evidence links osteoporosis, a disease characterized by loss of bone mass and structure, to changes in the dynamics of pulsatile parathyroid hormone (PTH) secretion. In our study we applied nonlinear and linear time series prediction to characterize the secretory dynamics of PTH in both healthy human subjects and patients with osteoporosis. Osteoporotic patients appear to lack periods of high predictability found in normal humans. In contrast to patients with osteoporosis patients with ...

Individually weight-adapted examination protocol in retrospectively ECG-gated MSCT of the heart

In the present study 12 diets, each one consisting of a pool of seven day diets, composed by four meals: breakfast, lunch, dinner and snack, adequate in energy and macro nutrients according to the RDA (Recommended Daily Allowance) recommendations, were elaborated and offered to a group of 12 men (19-42 years). The diets were collected by duplicate portion technique and dried by two different processes: freeze drying and 60 deg C ventilated oven drying. In the total, 24 diets were analyzed. The content of some minerals and trace elements (Ca, Fe, Mg, Mn, Na, Se and Zn) were determined by Instrumental Neutron Activation Analysis. The validation of methodology was made by analysis of the reference materials Typical Diet (NIST SRM 1548"a), Orchard Leaves (NIST SRM 1541) and Peach Leaves (NIST SRM 1547). The results observed by two different drying processes used were statistically compared by test T of Student. It was possible to conclude that the concentration means ...

Individually weight-adapted examination protocol in retrospectively ECG-gated MSCT of the heart

The standard protocol in multislice spiral CT (MSCT) angiography for coronary arteries with fixed tube current-time settings leads to an overexposure and thus to an unnecessary high radiation dose in patients with lower weight when compared to heavier patients. The purpose of this study was to estimate the effect of reducing the radiation dose by adapting the tube current-time settings individually. Fifty patients underwent retrospectively ECG-gated MSCT of the heart. In 25 patients (group A{sub 1}) a standard protocol with constant tube current-time settings was used (4 x 1-mm collimation, 120 kV, 400 mAs{sub eff}). Subsequently, artificial image noise was added to the data of these patients simulating a directive for weight-adapted tube current-time settings (group A{sub 2}). In the other 25 patients (group B) an alternative protocol with individually weight-adapted tube current-time settings was applied. The data of all groups were evaluated by a regression analysis.

Helical CT defecography

Elemental transfer from Chinese soil via the diet to the whole human body

The purpose of this work is to investigate the possible role of Helical CT defecography in pelvic floor disorders by comparing the results of the investigations with those of conventional defecography. The series analyzed consisted of 90 patients, namely 62 women and 28 men, ranging in age 24-82 years. They were all submitted to conventional defecography, and 18 questionable cases were also studied with Helical CT defecography. The conventional examination was performed during the 4 standard phases of resting, squeezing, Valsalva and straining; it is used a remote-control unit. The parameters for Helical CT defecography were: 5 mm beam collimation, pitch 2, 120 KV, 250 m As and 18-20 degrees gantry inclination to acquire coronal images of the pelvic floor. The rectal ampulla was distended with a bolus of 300 mL nonionic iodinated contrast agent (dilution: 3g/cc). The patient wore a napkin and was seated on the table, except for those who could not hold the position ...

Dynamic enhanced MRI of the subacromial bursa: correlation with arthroscopic and histological findings

Based on results from recent studies of elemental dietary intake and organ or tissue content for adult Chinese men, quoted nationwide elemental concentrations in Chinese soil and newly published national average consumption of dietary foods, values of both transfer coefficients and discrimination factor (DF) for transfer from soil via the diet to both critical organs and the whole body have been calculated for important elements in radiation protection, including alkaline earths, alkali metals, rare earths and other related elements. These calculations have used both the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) model and the DF method. In the UNSCEAR model, the basic parameters used to describe the transport of radionuclides are the transfer coefficients P_i_j, which describe the relationship of concentrations or other amounts between compartment i and the following compartment j, whereas the DF is the ratio between the ...

Distribution of blood lead, blood cadmium, urinary cadmium, and urinary arsenic levels in employees of a copper smelter

Objective: To assess dynamic MRI with Gd-DTPA enhancement for evaluating inflammatory changes in the subacromial bursa. Design and patients: We detected the signal intensity changes in dynamic MRI of the subacromial bursa, and confirmed these macroscopically by arthroscopy and histologically. The signal intensity was measured using built-in software, and the enhancement ratio (E ratio) was calculated from dynamic MR images. In addition, as a parameter of the rate of the increase in the signal intensity from 0 to 80 s, the mean increase per second in the E ratio was obtained as the coefficient of enhancement (CE). The correlation was studied of the E ratio and CE with the arthroscopic findings (redness, villous formation, thickening and adhesion), and of the E ratio and CE with the histological findings (capillary proliferation, papillary hyperplasia, fibrosis and inflammatory cell infiltration) of the subacromial bursa. Of patients with shoulder pain, this study included those with ...

Concurrent and adjuvant docetaxel with three-dimensional conformal radiation therapy plus androgen deprivation for high-risk prostate cancer: Preliminary results of a multicentre phase II trial

A cross-sectional medical examination of a copper smelter work force included determination of blood lead (Pb-B), zinc protoporphyrin (ZPP), blood cadmium (Cd-B), urinary cadmium (Cd-U), and urinary arsenic (As-U), since it was known that such metal impurities were present in the copper concentrate. A total of 776 copper smelter employees (680 active and 96 retirees and ex-employees) were examined. Another 144 men, never employed in the smelter, but who had worked in copper mines (and sometimes in gold mines) were also examined. Mean Pb-B, ZPP, Cd-B, and As-U were significantly higher in active copper smelter employees than in retirees or miners, indicating exposure and absorption in the copper smelter. Significant correlations between Pb-B and Cd-B, and Cd-U and As-U were present, confirming the common source of absorption. Although there was evidence for an increased lead absorption, this was very moderate, with practically no Pb-B levels in excess of 60 ...

Computed Tomography diagnosis of skeletal involvement in multiple myeloma

Background and purpose: We evaluate the feasibility of concomitant and adjuvant docetaxel combined with three-dimensional conformal radiotherapy (3D-CRT) and androgen deprivation in high-risk prostate carcinomas. Methods: Fifty men with high-risk localized prostate cancer (16), locally advanced (28) or very high-risk prostate cancer (6) were included. Seventy Gy were delivered on prostate and seminal vesicles in 35 fractions, concurrently with weekly docetaxel (20 mg/m"2). Three weeks after the completion of 3D-CRT, docetaxel was given for 3 cycles (60 mg/m"2), every 3 weeks. Patients had to receive LHRH agonist during 3 years. Results: The intent to treat analysis shows that four patients out of 15 stopped prematurely the chemotherapy due to grade 3-4 acute toxicity. In the per protocol analysis, 46 patients completed a full-dose chemoradiation regimen representing 413 cycles: five patients experienced a grade 3 toxicity, and 15 patients experienced a grade 2 ...

Clinical studies on cancer of the tongue

The authors assess the role of Computed Topography in the diagnosis and management of multiple myeloma (MM) and investigate if Computed Tomography findings can influence the clinical approach, prognosis and treatment. 273 multiple myeloma patients submitted to Computed Tomography June 1994, to December, 1996. The patients were 143 men and 130 women (mean age: 65 years): 143 were stage I, 38 stage II and 92 stage III according to Durie and Salomon's clinical classification. All patients were submitted to blood tests, spinal radiography and Computed Tomography, the latter with serial 5-mm scans on several vertebral bodies. Computed Tomography despicted vertebral arch and process involvement in 3 cases with the vertebral pedicle sign. Moreover, Computed Tomography proved superior to radiography in showing the spread of myelomatous masses into the soft tissues in a case with solitary permeative lesion in the left public bone, which facilitated subsequent biopsy. As for ...

Activity patterns in a panel of outdoor workers exposed to oxidant pollution

Thirty-nine previously untreated patients with squamous cell carcinoma of the tongue were treated by irradiation or a combination of irradiation and surgery, with or without chemotherapy, between January 1971 and December 1980. All of the patients had a follow-up period of at least nine years. Twenty-two patients were men and 17 were women. The average age was 50.1 years, with a range of 30 to 74 years. The absolute five-year survival rate was 82.1% and the cumulative ten-year survival rate 76.9% for these 39 patients. Cervical node metastases were clinically found on admission in 14 patients whose five-year survival rate was 64.3%, whereas it was 92.0% for 25 patients without metastasis. The absolute five-year survival rate decreased from 92.3% for patients with stage I lesions to 90.9%, 87.5% and 42.9% for those with stage II, stage III and stage IV lesions, respectively. Most of the patients received external irradiation and intraoral electron beam therapy. ...

A randomised controlled trial of intervention site radiotherapy in malignant pleural mesothelioma

We investigated summer activity patterns in a panel of volunteers drawn from a population segment with potentially high exposure to ambient oxidant pollution. The subjects were 15 men and 5 women aged 19-50, all of whom worked outdoors in the Los Angeles area at least 10 hr per week. The general approach was to (i) calibrate the relationship between ventilation rate (VR) and heart rate (HR) for each subject in controlled exercise; (ii) have subjects monitor their own normal activities with diaries and electronic HR recorders; (iii) estimate VR from HR recordings; and (iv) relate VR with diary descriptions of activities. Calibration data were fit to the equation log (VR) = (intercept) + (slope x HR), intercept and slope being determined separately for each individual to provide a specific equation to predict her/his VR from measured HR. Individuals' correlation coefficients relating log (VR) with HR ranged from 0.83 to 0.95. Subjects monitored themselves ...

Conversion of biomass, prediction and solution methods for ash agglomeration and related problems

Background and purpose: To assess the effectiveness of radiotherapy in preventing tumour seeding after chest drain or pleural biopsy in patients with malignant mesothelioma and to determine, if tract metastases appear, whether they are tender or troublesome to patients. Patients and methods: Patients with a histological diagnosis of pleural mesothelioma and an invasive procedure within the preceding 21 days were stratified by age, performance status and treatment centre. Randomisation was performed between immediate drain site radiotherapy 21 Gy in three fractions (XRT arm) or best supportive care (BSC) with follow-up to 12 months. Patients were asked to complete questionnaires on treatment toxicity and on symptoms from any tract metastases detected. Results: Sixty-one patients were recruited from two centres between 1998 and 2004; 56 men, 5 women, median age 70. 31 were allocated to drain site radiotherapy.

Computed Tomography of the diabetic kidney; La Tomografia Computerizzata nello studio del rene diabetico

When biomass is used as fuel for thermal conversion plants, minerals from the fuel can be responsible for major problems. Generally, these problems are associated with the existence and development of low melting compounds or eutectics, which form sticky layers. In a fluidised bed, this can result in bed-agglomeration and defluidisation. This causes local high temperature, which often accelerates the process. It ultimately can lead to a completely sintered bed content with a glassy phase gluing the bed particles together and shut-down of the plant. The main objective of the title project is to develop a methodology to predict ash/bed agglomeration and sintering problems, to indicate related problems and, furthermore, to identify solution methods to make different types of biomass streams more viable for energy production. Within the present study, selected fuels are subjected to different existing methods together with some new ones, in order to determine the agglomeration temperature. ...

Aortic non communicating dissections. A study with helical CT

The aims of this study were (a) to assess blood cadmium (B-Cd) concentrations and to establish a tentative reference interval; (b) to identify significant determinants of B-Cd, in a population from Umbria, Central Italy, which was not occupationally exposed to cadmium (Cd). Four hundred and thirty-four healthy blood-donors volunteered to answer a questionnaire and provide a blood sample for B-Cd analysis, which was performed by graphite furnace atomic absorption spectrophotometry. Blood Cd concentrations ranged from non-detectable values, i.e. below 0.1 {mu}g/l up to 3.4 {mu}g/l and were not normally distributed. The median values and the 95th percentiles were 0.7 and 2.0 {mu}g/l, respectively. Concentrations of B-Cd were more than double in smokers than in non-smokers, median values being 1.1 {mu}g/l and 0.5 {mu}g/l, respectively. In current smokers, B-Cd values correlated with the number of cigarettes smoked daily (r{sub s}=0.40, P=0.0001) and with the cumulative exposure to ...

Education Dean's Fraud Case Teaches U. of Louisville a Hard Lesson

The aims of investigation were to follow the Sr transport in the food chain from the flora to the fauna and humans, and its dependence on the geological origin og the plant site, industrial emissions, the age and site of plants, the part of plant used for nutrition and the strontium content in the drinking water, to determine the Sr intake of humans with the help of the duplicate method, and to estimate the apparent absorption rate and balance of strontium depending on of the form of diet (mixed or ovolactovegetarian), sex, season, age, region (geological origin of the living space) and method of intake measurement (duplicate or basket method). Strontium, an ultra trace element widespread in the earth's crust, is not essential and only mildly toxic for plants, animals and man according to current knowledge. The biological essentiality of Sr has not been investigated yet. Amoeba species living in sea water use Sr for the formation of their skeleton instead of Ca. There have been no Sr ...
