Full Text Available Evaluated under laboratory condition. The objective of the present study was to observe the effect of impregnated torn bednets on the number of bites by An. culicifacies A glass made tunnel test was designed to The effect of torn bednets treated with three dosages of cyfluthrin 5% EW, were induce hungry female mosquitoes to pass through holes cut in the pyrethroid treated nets. A guinea pig used as bait to attract mosquitoes through circular holes in the netting. With untreated netting, 72-87% of laboratory-reared females passed through the holes overnight, 64-92% blood-fed successfully and 0.3/9-4/3% died. When the netting was treated with cyfluthrin at doses of 25, 50 and 100 mg a.i./m2, the entry Index (the proportions that passed through the holes overnight were 43.37%, 42.82% and 24.72%; mortality rates were 66.31%, 81.45% and 95.99%; and the feeding rate were 45%, 27% and 3%. In conclusion it should be stressed that efficacy of pyrethroid impregnated bednets using “Tunnel Tests” showing acceptable protection rate both in lower and higher dosages as well as cause dead in the blood-fed mosquitoes. In addition, the higher dosages of these three dosages pyrethroid provided good levels of protection against An. culicifacies.

It is important to regenerate the tendon-to-bone interface after rotator cuff repair to prevent re-tears. The cells from torn human rotator cuff were targeted, and their capacity for multilineage differentiation was investigated. The edges of the rotator cuff were harvested during arthroscopic rotator cuff repair from nine patients, minced into pieces, and cultured on dishes. Adherent cells were cultured, phenotypically characterized. Then expandability, differentiation potential and gene expression were analyzed. Flow cytometry revealed that the mesenchymal stem cells (MSC)-related markers CD29, CD44, CD105, and CD166 were positive. However, CD14, CD34, and CD45 were negative. On RT-PCR analyses, the cells showed osteogenic, adipogenic, and chondrogenic potential after 3 weeks of culture under the respective differentiation conditions. In addition, SOX9, type II collagen, and type X collagen expression patterns during chondrogenesis were similar to those of endochondral ossification at the enthesis. The cells derived from torn human rotator cuff are multipotent mesenchymal stem cells with the ability to undergo multilineage differentiation, suggesting that MSCs form this tissue could be regenerative capacity for potential self-repair.

Malnutrition is a global public health problem especially in developing countries experiencing war/conflicts. War might be one of the socio-political factors influencing malnutrition in Sub-Saharan African (SSA) countries. This study aims at determining the influence of war on corruption, population (POP), number of population malnourished (NPU), food security and life expectancy (LE) in war-torn SSA countries (WTSSA) by comparing their malnutrition indicators. Fourteen countries in WTSSA were stratified into zones according to war incidences. Countries' secondary data on population (POP), NPU, Food Security Index (FSI), corruption perceptions index (CPI), Global Hunger Index (GHI) and LE were obtained from global published data. T test, multivariate and Pearson correlation analyses were performed to determine the relationship between CPI, POP, GHI, FSI, NPU, male LE (MLE) and female LE (FLE) in WTSSA at p Malnutrition indicators were similarly affected in WTSSA. Hunger influenced life expectancy. Policies promoting good governance, equity, peaceful co-existence, respect for human right and adequate food supply will aid malnutrition eradication and prevent war occurrences in Sub-Saharan African countries.

The purpose of this study was to describe the sonographic findings of healing in torn common extensor tendon of elbow after prolotherapy and to evaluate the value of US in the course of management of lateral epicondylitis. 12 common extensor tendons in eleven patients were examined by sonography before and after prolotherapy. On initial US examination, 11 tendons showed a partial tear and one tendon showed a full thickness but incomplete width tear. All patients were managed with prolotherapy several times(2 to 6 times). The time interval between the initial US and follow up US examination after treatment was from 4.5 to 6.5 months(mean ; 5.8 months). The findings of healing were evaluated with respect to the change of echogenicity(anechoic focus, hypoechoic focus), presence or absence of fibrillar pattern in the tendon on gray scale US, and focus of hypervascularity on color Doppler image. We used the visual analogue scale(VAS) of pain to assess the response to the treatment. All patients showed symptom improvement as the points drop on VAS in a range between 1.5 and 6.5(mean ; 4.5). In one tendon, a few echogenic lines were seen within the initially anechoic lesion(pattern I). In three tendons, most of the anechoic lesion(tear) was filled with fibrillar echogenicity except for a small focus of anechogenicity(pattern II). In two tendons, initial anechoic lesion in common extensor tendon was changed to same sized hypoechoic lesion with diffuse fibrillar pattern within the initial anechoic lesion (pattern III). In 6 tendons, initial anechoic lesion became smaller with diffuse fibrillar pattern were seen(pattern IV). Color Doppler examination was performed in 11 tendons after therapy and six of 11 tendons showed hypervascularity. Most important finding of healing in torn tendon is reappearance of fibrillar pattern in initial anechoic lesion(tear). The follow up sonography of the common extensor tendon in the course of treatment can be useful to evaluate the effects

Stock-outs, uncertainty and improvisation in access to healthcare in war-torn Northern Uganda.

Muyinda, Herbert; Mugisha, James

2015-12-01

Stock-outs, also known as shortages or complete absence of a particular inventory, in public health facilities have become a hallmark in Uganda's health system making the notions of persistent doubt in access to healthcare - uncertainty, and doing more with less - 'improvisation', very pronounced. The situation becomes more critical in post-conflict areas with an over whelming burden of preexisting and conflict-related ailments amidst weak health systems. Particularly in the war-torn Northern Uganda, the intersection between the effects of violent conflict and shortage of medications is striking. There are problems getting the right type of medications to the right people at the right time, causing persistent shortages and uncertainty in access to healthcare. With reference to patients on Antiretroviral Therapy (ART), we present temporal trends in access to healthcare in the context of medication shortages in conflict-affected areas. We examine uncertainties in access to care, and how patients, medical practitioners, and the state - the key actors in the domain of supplying and utilizing medicines, respond. Our observation is that, while improvisation is a feature of biomedicine and facilitates problem solving in daily life, it is largely contextual. Given the rapidly evolving contexts and social and professional sensitivities that characterize war affected areas, there is a need for deliberate healthcare programs tailored to the unique needs of people and to the shaping of appropriate policies in post-conflict settings, which call for more North-South collaboration on equal terms.

1997-01-01

This article describes a UN HIV/AIDS and sexually transmitted disease (STD) project in war-torn south Sudan. The 3-year project relies on collaboration between adversaries and implementation in government-held and rebel-controlled areas. The project aims to reduce the risk and vulnerability to HIV/AIDS/STDs and to foster dialogue among adversaries as a means of conflict resolution. The World Health Organization will contribute technical assistance. Local partners including the government, the Southern Sudan Independence Movement, and the Sudanese People's Liberation Movement will contribute resources valued at about $100,000. The total UN contribution is about $300,000. HIV transmission has increased due to a high concentration of military personnel and population displacement. Available information suggests that the south has the highest HIV prevalence and 46% of known AIDS cases. STDs increased from 2.3% in 1989 to 14.1% in 1994. The project focuses on women, youth, and other vulnerable groups. The project is in its 9-month preparatory phase. The preparatory phase includes analysis of the HIV/AIDS/STD situation, design of a sustainable program, assessment of causative factors, and establishment of a mechanism for effectively coordinating the project. The civil war will affect priorities, strategies, and activities. In government-controlled areas, the Sudan National AIDS program will conduct activities. In non-government areas, the Sudan Rehabilitation and Relief Association, the Relief Association for South Sudan, and health and humanitarian authorities of the liberation groups will conduct programs. The UN Office of Special Projects will provide oversight during the preparatory phase. Sudan's UN Country Theme Group on HIV/AIDS will be the coordinating group.

Full Text Available Military conflict has been a major challenge in the detection and control of emerging infectious diseases such as malaria. It poses issues associated with enhancing emergence and transmission of infectious diseases by destroying infrastructure and collapsing healthcare systems. The Orakzai agency in Pakistan has witnessed a series of intense violence and destruction. Military conflicts and instability in Afghanistan have resulted in the migration of refugees into the area and possible introduction of many infectious disease epidemics. Due to the ongoing violence and Talibanization, it has been a challenge to conduct an epidemiological study.All patients were sampled within the transmission season. After a detailed clinical investigation of patients, data were recorded. Baseline venous blood samples were taken for microscopy and nested polymerase chain reaction (nPCR analysis. Plasmodium species were detected using nested PCR (nPCR and amplification of the small subunit ribosomal ribonucleic acid (ssrRNA genes using the primer pairs. We report a clinical assessment of the epidemic situation of malaria caused by Plasmodium vivax (86.5% and Plasmodium falciparum (11.79% infections with analysis of complications in patients such as decompensated shock (41%, anemia (8.98%, hypoglycaemia (7.3%, multiple convulsions (6.7%, hyperpyrexia (6.17%, jaundice (5%, and hyperparasitaemia (4.49%.This overlooked distribution of P. vivax should be considered by malaria control strategy makers in the world and by the Government of Pakistan. In our study, children were the most susceptible population to malaria infection while they were the least expected to use satisfactory prevention strategies in such a war-torn deprived region. Local health authorities should initiate malaria awareness programs in schools and malaria-related education should be further promoted at the local level reaching out to both children and parents.

Feeling trapped and being torn: Physicians' narratives about ethical dilemmas in hemodialysis care that evoke a troubled conscience

Science.gov (United States)

2011-01-01

Background This study is part of a major study about difficulties in communicating ethical problems within and among professional groups working in hemodialysis care. Describing experiences of ethically difficult situations that induce a troubled conscience may raise consciousness about ethical problems and thereby open the way to further reflection. The aim of this study was to illuminate the meanings of being in ethically difficult situations that led to the burden of a troubled conscience, as narrated by physicians working in dialysis care. Method A phenomenological hermeneutic method was used to analyze the transcribed narrative interviews with five physicians who had varying lengths of experience in nephrology. Results The analysis shows that physicians working in hemodialysis care suffered from a troubled conscience when they felt torn by conflicting demands and trapped in irresolution. They faced ethical dilemmas where they were forced to make crucial decisions about life or death, or to prioritize when squeezed between time restraints and professional and personal demands. In these ethical dilemmas the physicians avoided arousing conflicts, were afraid of using their authority, were burdened by moral responsibility and felt devalued and questioned about their way of handling the situation. The findings point to another way of encountering ethical dilemmas, being guided by their conscience. This mean sharing the agony of deciding how to act, being brave enough to bring up the crucial problem, feeling certain that better ways of acting have not been overlooked, being respected and confirmed regarding decisions made. Conclusion The meanings of being in ethically difficult situations that led to the burden of a troubled conscience in those working in hemodialysis care, indicate the importance of increasing the level of communication within and among various professional groups - to transform being burdened by a troubled conscience into using conscience as a

2006-01-01

Within a period of 2 years starting from April 2000 to November 2002, fifty (50) cases of torn anterior cruciate ligament (ACL) were treated and followed up using our simple modified technique in a retrospective non-randomized study conducted in Saudi-German Hospital, Saudi Arabia. All of which had torn ACL either isolated or associated with meniscal tear. Some of our study group was subjected arthroscopic interference in the same knee before either in the form of ACL reconstruction using P-T-B graft or for menisectomy. During this study per-operative evaluation, intra-operative technique and post-operative follow-up were standardized, with maximum follow-up period of 19 months and minimum follow-up period of 9 month. The final outcome was graded according to Lyshom knee score (1982). The mean age at surgery was 26.5 (from 17 to 36 years). The study group included 11 isolated torn ACL, 29 torn ACL with tear in the medial meniscus, 4 torn ACL with lateral meniscus tear and 6 cases with torn ACL associated with tear in both menisci. All of the cases were treated using the same technique. (author)

Diagnosis of radial tear of posterior horn of medial meniscus by MR imaging. Prospective study

International Nuclear Information System (INIS)

Motoyama, Tatsuo; Ihara, Hidetoshi; Kawashima, Mahito

2002-01-01

It is not easy to detect radial tears of the posterior horn of the medial meniscus (torn posterior horn) under arthroscopy if the surgeon does not notice the tear before arthroscopy. Occasionally the tear goes undetected or is missed during arthroscopy. The sagittal view of MR imaging is very useful for diagnosing torn posterior horns. The normal posterior horn of the medial meniscus appears as an image of low intensity triangle of the sagittal MRI medial slice next to the PCL. On the contrary, the image of the torn posterior horn shows a high intensity triangle, so we refer to the feature as a white meniscus sign. We prospectively examined the accuracy of white meniscus sign of MRI. Forty-two knees in 41 patients were studied. They were over 40 years of age, diagnosed with medial meniscus tear and had undergone MRI before arthroscopy. Before arthroscopy, we predicted the existence of torn posterior horn by the white meniscus sign and examined the accuracy of the MRI after arthroscopy. Total accuracy rate was 90.5%, sensitivity was 94.1%, and specificity was 88.0%. We concluded that the white meniscus sign on MRI is very useful for defecting torn posterior horn of the medial meniscus. (author)

Rotator cuff repair retear rates range from 25% to 90%, necessitating methods to improve repair strength. Although numerous laboratory studies have compared single-row with double-row fixation properties, little is known regarding regional (ie, medial vs lateral) suture retention properties in intact and torn tendons. A torn supraspinatus tendon will have reduced suture retention properties on the lateral aspect of the tendon compared with the more medial musculotendinous junction. Controlled laboratory study. Human supraspinatus tendons (torn and intact) were randomly assigned for suture retention mechanical testing, ultrastructural collagen fibril analysis, or histologic testing after suture pullout testing. For biomechanical evaluation, sutures were placed either at the musculotendinous junction (medial) or 10 mm from the free margin (lateral), and tendons were elongated to failure. Collagen fibril assessments were performed using transmission electron microscopy. Intact tendons showed no regional differences with respect to suture retention properties. In contrast, among torn tendons, the medial region exhibited significantly higher stiffness and work values relative to the lateral region. For the lateral region, work to 10-mm displacement (1592 ± 261 N-mm) and maximum load (265 ± 44 N) for intact tendons were significantly higher (P .05). Regression analyses for the intact and torn groups revealed generally low correlations between donor age and the 3 biomechanical indices. For both intact and torn tendons, the mean fibril diameter and area density were greater in the medial region relative to the lateral (P ≤ .05). In the lateral tendon, but not the medial region, torn specimens showed a significantly lower fibril area fraction (48.3% ± 3.8%) than intact specimens (56.7% ± 3.6%, P row after double-row repair. Larger diameter collagen fibrils as well as greater fibril area fraction in the medial supraspinatus tendon may provide greater resistance to

Shoulder complaints are common in the elderly and hamper daily functioning. These complaints are often caused by tears in the muscle-tendon units of the rotator cuff (RC). The four RC muscles stabilize the shoulder joint. While some RC muscles are frequently torn in shoulder complaints others remain intact. The pathological changes in RC muscles are poorly understood. We investigated changes in RC muscle pathology combining radiological and histological procedures. We measured cross sectional area (CSA) and fatty infiltration from Magnetic Resonance Imaging with Arthrography (MRA) in subjects without (N = 294) and with (N = 109) RC-tears. Normalized muscle CSA of the four RC muscles and the deltoid shoulder muscle were compared and age-associated patterns of muscle atrophy and fatty infiltration were constructed. We identified two distinct age-associated patterns: in the supraspinatus and subscapularis RC muscles CSAs continuously declined throughout adulthood, whereas in the infraspinatus and deltoid reduced CSA was prominent from midlife onwards. In the teres minor, CSA was unchanged with age. Most importantly, age-associated patterns were highly similar between subjects without RC tear and those with RC-tears. This suggests that extensive RC muscle atrophy during aging could contribute to RC pathology. We compared muscle pathology between torn infraspinatus and non-torn teres minor and the deltoid in two patients with a massive RC-tear. In the torn infraspinatus we found pronounced fatty droplets, an increase in extracellular collagen-1, a loss of myosin heavy chain-1 expression in myofibers and an increase in Pax7-positive cells. However, the adjacent intact teres minor and deltoid exhibited healthy muscle features. This suggests that satellite cells and the extracellular matrix may contribute to extensive muscle fibrosis in torn RC. We suggest that torn RC muscles display hallmarks of muscle aging whereas the teres minor could represent an aging

We identified two distinct age-associated patterns: in the supraspinatus and subscapularis RC muscles CSAs continuously declined throughout adulthood, whereas in the infraspinatus and deltoid reduced CSA was prominent from midlife onwards. In the teres minor, CSA was unchanged with age. Most importantly, age-associated patterns were highly similar between subjects without RC tear and those with RC-tears. This suggests that extensive RC muscle atrophy during aging could contribute to RC pathology. We compared muscle pathology between torn infraspinatus and non-torn teres minor and the deltoid in two patients with a massive RC-tear. In the torn infraspinatus we found pronounced fatty droplets, an increase in extracellular collagen-1, a loss of myosin heavy chain-1 expression in myofibers and an increase in Pax7-positive cells. However, the adjacent intact teres minor and deltoid exhibited healthy muscle features. This suggests that satellite cells and the extracellular matrix may contribute to extensive muscle fibrosis in torn RC. We suggest that torn RC muscles display hallmarks of muscle aging whereas the teres minor could represent an aging

Full Text Available In restinga areas of Marambaia, Rio de Janeiro, we recorded nine species of lizards, grouped in four families. The morphometric analysis suggested an invasion-structured pattern, with two distinct groups of species in the community: the "ground-runners", composed of animals with robust bodies and long limbs, represented by Tropidurus torquatus (Wied, 1820, Ameiva ameiva (Linnaeus, 1758, Liolaemus lutzae Mertens, 1938, Cnemidophorus littoralis Rocha, Araujo, Vrcibradic & Costa, 2000 and Tupinambis merianae (Duméril & Bibron, 1839; and the "hiders", composed of small-bodied animals with short limbs, represented by Hemidactylus mabouia (Moreau de Jonnès, 1818, Gymnodactylus darwinii (Gray, 1845, Mabuya agilis (Raddi, 1823 and M. macrorhyncha Hoge, 1947. The morphological relationships within the restinga lizard community reflect the influence of the habitat physical structure: bromeliad availability and other refugia, used by the "hiders", and the distribution of open areas, used by the "ground-runners". Our results also indicate that the restingas hold "ecomorphological spaces" (vacant niches available for occupation by additional lizard species.Em áreas de restinga da Marambaia, Rio de Janeiro, foram registradas nove espécies de lagartos, pertencentes a quatro famílias.

To attempt to visualize the ligament with standard 1.5-tesla magnetic resonance imaging (MRI) in the acute anterior cruciate ligament (ACL)-torn knee, and if it is visible, attempt to characterize it as torn or intact at its femoral, meniscal, and tibial attachment sites. This was a retrospective MRI study based on arthroscopic findings of a known ACL tear in 72 patients between the years 2006 and 2010. Patients all had hamstring ACL reconstructions, no concomitant lateral collateral ligament, or posterolateral corner injury based on imaging and physical examination, and had a preoperative 1.5-tesla MRI scan with standard sequences performed within 3 weeks of the injury. Two fellowship-trained musculoskeletal radiologists retrospectively reviewed the preoperative MRI for visualization of the anterolateral ligament (ALL) for concomitant tears. Inter- and intraobserver reliability was calculated. Learning effect was analyzed to determine if radiologists' agreement improved as reads progressed. Both radiologists were able to visualize the ALL in 100% of the scans. Overall, ALL tears were noted in 26% by radiologist 1 and in 62% by radiologist 2. The agreement between the ligament being torn or not had a kappa of 0.54 between radiologists. The agreements in torn or not torn between radiologists in the femoral, meniscal, and tibial sites were 0.14, 0.15, and 0.31. The intraobserver reliability by radiologist 1 for femoral, meniscal, and tibial tears was 0.04, 0.57, and 0.54 respectively. For radiologist 2, they were 0.75, 0.61, and 0.55. There was no learning effect noted. ALL tears are currently unable to be reliably identified as torn or intact on standard 1.5-tesla MRI sequences. Proper imaging sequences are of crucial importance to reliably follow these tears to determine their clinical significance. Level IV, therapeutic case series study.

To compare the diagnostic efficacy of the four magnetic resonance imaging (MRI) sequences that compose the standard protocol for the study of the knee in our center when employed in the examination of anterior cruciate ligament (ACL). A prospective study was carried out based on MRI findings in the knees of 326 consecutive patients. Sagittal [proton density (PD w eighted turbo-spin-echo and T2*-weighted gradient echo], coronal (PD-weighted turbo-spin-echo with fat suppression) and transverse (T2*-weighted gradient echo with magnetization transfer) images were evaluated. Each sequence was analyzed independently by two radiologists, while another two assessed all the sequences together with the clinical findings. Four categories were established: normal ACL, partially torn, completely torn and synovialized. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) with respect to the definitive diagnosis were calculated for each sequence. The statistical analysis of the findings for each category was done using the chi-squared test and the Kappa test was employed to assess the degree of agreement. According to the final diagnosis, 263 ACL were normal, 29 were partially torn, 33 were completely torn and there was 1 case of synovialization associated with a completely torn ACL. The relationship between the analysis of the ACL according to each sequence and the definitive diagnosis was very significant (p<0.001) and the agreement was excellent. All the sequences presented similar levels of diagnostic precision. The coronal sequence had least number of diagnostic errors (2.1%). The combinations of imaging techniques that resulted in the lowest error rate with respect to the definitive diagnosis were coronal PD-weighted turbo-spin-echo with fat suppression and sagittal PD-weighted turbo-spin-echo. Coronal images are highly precise in the evaluation of ACL. Sagittal sequences are the most valid for diagnosis of torn ACL. Transverse

2014-12-01

Full Text Available Vascular streak dieback caused by the fungus Oncobasidium theobromae is one of the important diseases in cocoa crop in Indonesia. One approach to control the disease is by using fungicides. The aim of this research was to determine the effect of class triazole fungicides to the intensity of the vascular streak dieback disease on cocoa seedling phase, immature and mature cocoa. Experiments were conducted in Kotta Blater, PTPN XII and Kaliwining, Indonesian  Coffee and Cocoa Research Institute. Flutriafol 250 g/l with a concentration 0,05%, 0,1% and 0,15% foliar sprayed on cocoa seedlings, immature and mature cocoa. Active compound combination of Azoxystrobin and Difenoconazole with 0,1% concentration used as a comparation fungicides. The result showed that Flutriafol with 0,05%, 0,1% and 0,15% concentration and Azoxystrobin & Difenoconazol with 0,1% concentration could suppress the vascular streak dieback disease on seedlings. On immature plants, the application of Flutriafol was not effectively suppress the vascular streak dieback disease whereas the fungicide comparison could suppress with the efficacy level of 46.22%. On mature plants,both of fungicides could not suppress the vascular streak dieback disease. Key words: Fungicide, cocoa, vascular streak dieback, triazole, flutriafol, azoxystrobin+difenoconazol

Lake and river ice seasonality (dates of ice freeze and breakup) responds sensitively to climatic change and variability. We analyzed climate-related changes using direct human observations of ice freeze dates (1443–2014) for Lake Suwa, Japan, and of ice breakup dates (1693–2013) for Torne River, Finland. We found a rich array of changes in ice seasonality of two inland waters from geographically distant regions: namely a shift towards later ice formation for Suwa and earlier spring melt for Torne, increasing frequencies of years with warm extremes, changing inter-annual variability, waning of dominant inter-decadal quasi-periodic dynamics, and stronger correlations of ice seasonality with atmospheric CO2 concentration and air temperature after the start of the Industrial Revolution. Although local factors, including human population growth, land use change, and water management influence Suwa and Torne, the general patterns of ice seasonality are similar for both systems, suggesting that global processes including climate change and variability are driving the long-term changes in ice seasonality.

The accuracy of MRI in assessing graft integrity after anterior cruciate ligament reconstruction

International Nuclear Information System (INIS)

Nakayama, Yoshihito; Shirai, Yasumasa; Narita, Tetsuya; Mori, Atsushi; Kobayashi, Kaoru

2001-01-01

To evaluate the efficacy of MRI in assessing anterior cruciate ligament (ACL) reconstruction graft integrity, we compared MRI findings with arthroscopic findings in 52 patients who had undergone arthroscopically assisted ACL reconstruction using semitendinosus and gracilis tendons augmented by woven polyester. MRI and arthroscopy were carried out 12 months after the operation. The MR appearance of ACL grafts was categorized into 3 types by signal intensity and continuity of the ligament according to Rak's method: well-defined type: the graft was visualized as a smoothly continuous band with low signal over the entire course; intermediate type: signal intensity increased and a low-signal band was visualized only in part of the graft; indiscernible type: the graft was not identified through the joint cavity due to markedly increased signal intensity. When the MR appearance of intermediate or indiscernible types was defined as torn, the grafts were presumed to be torn in 9 patients whose arthroscopic findings were 7 intact and 2 torn grafts. All cases with intact MRI findings were intact on arthroscopic examination. Thus, the sensitivity, specificity and accuracy of MRI as an evaluative tool for ACL graft tears were 100%, 86% and 86.5%, respectively. (author)

Meniscal tears are often associated with anterior cruciate ligament (ACL) injury and may lead to pain and discomfort in humans. Maximal preservation of meniscal tissue is highly desirable to mitigate the progression of osteoarthritis. Guidelines of which meniscal tears are amenable to repair and what part of damaged tissues should be removed are elusive and lacking consensus. Images of microstructural changes in meniscus would potentially guide the surgeons to manage the meniscal tears better, but the resolution of current diagnostic techniques is limited for this application. In this study, we demonstrated the feasibility of using optical coherence tomography (OCT) for the diagnosis of meniscal pathology. Torn medial menisci were collected from dogs with ACL insufficiency. The torn meniscus was divided into three tissue samples and scanned by OCT and scanning electron microscopy (SEM). OCT and SEM images of torn menisci were compared. Each sample was evaluated for gross and microstructural abnormalities and reduction or loss of birefringence from the OCT images. The abnormalities detected with OCT were described for each type of tear. OCT holds promise in non-destructive and fast assessment of microstructural changes and tissue birefringence of meniscal tears. Future development of intraoperative OCT may help surgeons in the decision making of meniscal treatment.

Background: The significance of borderline magnetic resonance (MR) findings that are equivocal for a tear of the knee meniscus remains uncertain. Given their higher signal-to-noise ratio (SNR) and greater spatial resolution, these equivocal meniscal tears could be expected to be less frequent using a 3.0T MR system. Purpose: To investigate the prevalence of equivocal meniscal tears using 3.0T MR, and to study their impact on MR accuracy compared with arthroscopy in the detection of meniscal tears. Material and Methods: The medical records of 100 patients who underwent 3.0T MR imaging and subsequent arthroscopy of the knee were retrospectively reviewed. Two observers interpreted MR images in consensus, and menisci were diagnosed as torn (abnormality on two or more images), equivocal for a tear (abnormality on one image), or intact, using arthroscopy as the standard of reference. The prevalence of equivocal meniscal tears was assessed, and MR accuracy was calculated as follows: first, considering both torn menisci and equivocal diagnoses as positive for a tear; and second, considering only torn menisci as positive for a tear. Results: Evidence of meniscal tears on MR images was equivocal in 12 medial (12%) and three lateral (3%) menisci. Of these equivocal MR diagnoses, tears were found at arthroscopy in eight medial and one lateral meniscus. In our study, the specificity and positive predictive value increased for both the medial and lateral meniscus when only menisci with two or more abnormal images were considered to be torn: from 80% and 89% to 91% and 94% for the medial meniscus, and from 91% and 73% to 93% and 78% for the lateral meniscus, respectively. Conclusion: Subtle findings that are equivocal for a tear of the knee meniscus still make MR diagnosis difficult, even at 3.0T. We recommend that radiologists should rather be descriptive in reporting subtle or equivocal MR findings, alerting the clinician of possible meniscal tear

The prevalence of equivocal meniscal tears was assessed, and MR accuracy was calculated as follows: first, considering both torn menisci and equivocal diagnoses as positive for a tear; and second, considering only torn menisci as positive for a tear. Results: Evidence of meniscal tears on MR images was equivocal in 12 medial (12%) and three lateral (3%) menisci. Of these equivocal MR diagnoses, tears were found at arthroscopy in eight medial and one lateral meniscus. In our study, the specificity and positive predictive value increased for both the medial and lateral meniscus when only menisci with two or more abnormal images were considered to be torn: from 80% and 89% to 91% and 94% for the medial meniscus, and from 91% and 73% to 93% and 78% for the lateral meniscus, respectively. Conclusion: Subtle findings that are equivocal for a tear of the knee meniscus still make MR diagnosis difficult, even at 3.0T. We recommend that radiologists should rather be descriptive in reporting subtle or equivocal MR findings, alerting the clinician of possible meniscal tear

First reports of ectoparasites collected from wild-caught exotic reptiles in Florida.

We collected ectoparasites from 27 of 51 wild-caught, free-ranging exotic reptiles examined in Florida from 2003 to 2008. Sampled animals represented eight species, five of which yielded ectoparasites. Reported new parasite distribution records for the United States include the following: the first collection of the African tick Amblyomma latum (Koch) from a wild-caught animal [ball python, Python regius (Shaw)] in the United States; the first collection of the lizard scale mite Hirstiella stamii (Jack) from any wild-caught animal [green iguana, Iguana iguana (L.)]; and the first collection of the lizard scale mite Geckobia hemidactyli (Lawrence) in the continental United States from a wild-caught tropical house gecko, Hemidactylus mabouia (Moreau de Jonnès). We also report the first collections of the Neotropical ticks Amblyomma rotundatum (Koch) and Amblyomma dissimile (Koch) from wild-caught Burmese pythons, Python molurus bivittatus (Kuhl); the first collections of A. dissimile from a wild-caught African savannah monitor, Varanus exanthematicus (Bosc); and from wild-caught green iguanas in the United States; and the first collections of the native chiggers Eutrombicula splendens (Ewing) and Eutrombicula cinnabaris (Ewing) from wild-caught Burmese pythons. These reports may only suggest the diversity of reptile ectoparasites introduced and established in Florida and the new host-parasite relationships that have developed among exotic and native ectoparasites and established exotic reptiles.

Interleukin (IL)-22 plays important roles in the development of arterial disease, including atherosclerosis and hypertension. However, the relationship between IL-22 and acute thoracic aortic dissection (TAD) remains unknown. Blood samples were collected from patients with chest pain who underwent computed tomography angiography of the thoracic aorta but had no known preoperative diagnosis of coronary artery disease, peripheral artery disease, arthritis, and/or membranous nephropathy. Patients were divided into non-AD (NAD) and TAD groups, and the plasma concentrations of IL-22, IL-6 and tumor necrosis factor (TNF)-α were measured. In addition, aortic tissue samples from acute TAD patients and normal donors were collected, and the expression levels of IL-22 and IL-22 receptor 1 (IL-22R1) were measured. IL-22, IL-6 and TNF-α levels were significantly higher in acute TAD patients than in NAD patients (IL-22, NAD group: 27.0 (19.1, 38.6) pg/ml vs. TAD group: 32.9 (20.6, 58.3) pg/ml, pTAD (OR 1.169, 95% CI 1.069 to 1.277; p=0.001). In addition, compared with aortic tissue of normal controls, TAD aortas showed increased expression of IL-22 and IL-22R1, especially in the torn section (IL-22, non-torn section: 2.8±0.5/HPF vs. torn section 2.8±0.5/HPF, pTAD.

Women, war, and reproductive health in developing countries.

Globally, millions of people are affected by war and conflicts every year. However, women have increasingly suffered the greatest harm by war in more different ways than men. We conceptualize a reproductive rights approach toward examining the effects of war on women's reproductive health in developing countries. Given the rising concerns of exclusion to adequately address women's rights, sexual and gender-based violence, and post-conflict accountability, we specifically focus on the limitations of the Minimum Initial Service Package, a UN-sponsored reproductive health service program in conflict zones while offering a broad reproductive rights-based conceptual lens for examining reproductive health care services in war-torn areas. In addition, we discuss the roles social workers may play at both micro and macro levels in war-torn areas to bring about both short term and long term gains in women's reproductive health.

Occurrence and distribution of the exotic lizard Hemidactylus mabouia Moreau de Jonnès, 1818 in Ilha Grande, RJ, Brazil

Directory of Open Access Journals (Sweden)

CFD Rocha

Full Text Available The gekkonid lizard Hemidactylus mabouia is an exotic species in Brazil and is found in different ecosystems. This species was recorded at Ilha Grande, RJ, one of the largest insular remains of the Atlantic Rainforest in Brazil. In this study, the occurrence of H. mabouia was determined throughout the island, including the rain forest, restinga and anthropic environments. We used the active search method in points along 19 trails that surround Ilha Grande. At each regular interval of 100 m, we searched for the presence of H. mabouia. The species was recorded in a total of 100 points among the 719 sampled and, in all cases, the occurrence of the lizard corresponded to points located in anthropic or perianthropic areas. As most of Ilha Grande is covered by dense tropical rain forest, we believe this has restricted the invasion of H. mabouia in natural environments within the island.

To investigate the hypothesis that the intravoxel incoherent motion (IVIM) diffusion-weighted imaging may depict microcirculation of meniscus and the perfusion changes in meniscal disorder. Fifty patients received diffusion-weighted MRI with multiple b-values ranging from 0 to 400 s/mm 2 . The four horns of the menisci were divided into normal, degenerated, and torn groups. IVIM parameters including perfusion fraction (f), pseudo-diffusion coefficient (D*), true diffusion coefficient (D), and the product of f and D* (f D*) of normal meniscal red zone and white zone were derived and compared for microcirculation changes of normal, degenerated, and torn posterior horn of the medial meniscus (PMM). The parameters between red and white zones among the groups were compared. Significant differences were considered when P meniscus and the perfusion changes in meniscal disorder. 3 J. Magn. Reson.

Muscle Progenitor Cell Regenerative Capacity in the Torn Rotator Cuff

Meyer, Gretchen A.; Farris, Ashley L.; Sato, Eugene; Gibbons, Michael; Lane, John G.; Ward, Samuel R.; Engler, Adam J.

2014-01-01

Chronic rotator cuff (RC) tears affect a large portion of the population and result in substantial upper extremity impairment, shoulder weakness, pain and limited range of motion. Regardless of surgical or conservative treatment, persistent atrophic muscle changes limit functional restoration and may contribute to surgical failure. We hypothesized that deficits in the skeletal muscle progenitor (SMP) cell pool could contribute to poor muscle recovery following tendon repair. Biopsies were obtained from patients undergoing arthroscopic RC surgery. The SMP population was quantified, isolated and assayed in culture for its ability to proliferate and fuse in-vitro and in-vivo. The SMP population was larger in muscles from cuffs with partial tears compared with no tears or full thickness tears. However, SMPs from muscles in the partial tear group also exhibited reduced proliferative ability. Cells from all cuff states were able to fuse robustly in culture and engraft when injected into injured mouse muscle, suggesting that when given the correct signals, SMPs are capable of contributing to muscle hypertrophy and regeneration regardless of tear severity. The fact that this does not appear to happen in-vivo helps focus future therapeutic targets for promoting muscle recovery following rotator cuff repairs and may help improve clinical outcomes.

Dead wood for biodiversity - foresters torn between mistrust and commitment

International Nuclear Information System (INIS)

Deuffic, Philippe

2010-01-01

Dead wood is a key element in forest biodiversity, which is used as one of the indicators for sustainable development of forests. A survey was conducted among foresters and users in the Landes de Gascogne and ile-de-France areas so as to assess practises and social representations associated with dead wood. From the results of the survey, it appears that there is a diversity of practices and divergences about the implications connected with dead wood. The 64 respondents can be divided into roughly six groups (G1: 'industrial foresters', G2: the 'silvicultural foresters', G3: the 'remote foresters', G4: the 'environmentalist foresters', G5: the 'naturalists' and G6: the 'users'). Among other things, they can be differentiated by their management practises, their degree of knowledge about and concern with ecology, their social networks, their aesthetic judgment, their perception of risks and their economic requirements. While underscoring the scarce popularity on average of the biodiversity-related issues, this sociological survey also highlights: the need for a minimal regulatory framework to achieve integrated retention of dead wood, the serious concern of forest managers in the Landes with plant health risks associated with dead wood, and the need for a functional justification for keeping dead wood in the ecosystem.

A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

Seventy-six AMMHs were analyzed in 66 patients [35 females and 31 males, mean age 49.3 ± 15.2 years (range 17-81)]. Eleven percent of AMMHs were poorly visualized, 51 % visualized, and 37 % well visualized. Seven percent demonstrated round, 73 % ovoid, and 21 % flat/lenticular tendon morphologies. Most (88 %) demonstrated typical origins. Average cross-sectional area (CSA) was 22.4 ± 10.6 mm 2 (range 6-56), diameter was 7.2 ± 2.5 mm (range 2.9-15), medial distance from the semimembranosus tendon was 7.5 ± 2.5 mm (range 3-14), and tendon length was 6.8 ± 3.3 cm (range 1.2-14.1). There was no gender difference in AMMH anatomic measurements or correlation between age and CSA or diameter. Of 17 complete hamstring avulsion cases, the AMMH was intact in 13, partially torn in 3, and completely torn in 1. The AMMH is a constant finding with variable anatomic characteristics. It is visualized or well visualized by MRI in 88 % of cases and is a sizable tendon located in close proximity to the semimembranosus tendon. Because it is uncommonly completely torn (6 %) in cases of complete hamstring avulsion, radiologists should be aware of its presence and appearance to avoid diagnostic confusion. (orig.)

ARTHROSCOPIC MENISCUS REPAIR WITH BIOABSORBABLE ARROWS IN LOCAL ANESTHESIA

Directory of Open Access Journals (Sweden)

Vladimir Senekovič

2004-11-01

Full Text Available Background. The menisci have important function in the knee joint. Because of this it is universally accepted that we have to preserve them as much as possible. After open and partially arthroscopic suture techniques new methods of all-inside meniscus repair with bioabsorbable arrows have been developed in the last decade. The meniscus repair using these arrows represents an easy task for a skilled surgeon. In addition, it can be performed in local anesthesia. We have evaluated the results of the first group of patients who were treated by this method.Methods. From February 2001 to August 2002 15 patients with torn meniscuses have been treated at the Clinical Department for Traumatology, University Medical centre, Ljubljana. We repaired their torn menisci arthroscopically with bioabsorbable arrows in local anesthesia. We divided patients in three groups: a group with isolated meniscus injury, a group with meniscus injury and anterior cruciate ligament injury and a group with associated pathology. Four patients had incarcerated meniscuses. Preoperative Lysholm score in the first group was 38, in the second 42 and in the third group 48. We repaired 12 medial and 3 lateral meniscuses. On average we need 45 minutes for therapeutic arthroscopy. Torn meniscus was fixated with minimum of 1 and maximum of 5 bioabsorbable arrows. All patients except one had the affected knee immobilized with cylinder plaster for 15 days on average.Results. At least three months after the arthroscopic fixation of the torn meniscus in local anesthesia another clinical evaluation was made. In all groups significant improvement was observed regarding the range of motions and absence of pain. Postoperative Lysholm score in the first group was 89, in the second 75 and in the third 71. Average deficit of flexion was 3 degrees while extension was full. One patient complained about the same pain in the joint, he underwent another arthroscopy which showed that the meniscus was

We describe a case of a 76-year old male who presented with progressive dyspnoea. He underwent an aortic valve replacement with a Freedom SOLO bioprosthesis 6 years ago. Transthoracic echocardiography showed a moderate-to-severe leakage of the Freedom SOLO bioprosthesis. During surgical reintervention, a partial tear of the left coronary cusp was seen from the commissure of the right coronary cusp to its base. After radiographic and microscopic examination, no clear cause was found for the failure of this Freedom SOLO bioprosthesis. To our knowledge, this is the third failure of a Freedom SOLO bioprosthesis reported in the literature. When the long-term follow-up of the Freedom SOLO bioprosthesis is available, it has to be compared with other bioprosthesis for long-term durability.

Two war-torn soldiers: combat-related trauma through an intersubjective lens.

Science.gov (United States)

Carr, Russell B

2013-01-01

The author, himself an Iraq war veteran, presents a contemporary psychodynamic understanding, known as intersubjective therapy, of combat-related Post-traumatic Stress Disorder (PTSD). At the onset of this case example, the patient was highly suicidal and his PTSD symptoms had not responded to a first-line treatment: manualized cognitive processing therapy. Robert Stolorow's intersubjective, psychodynamic approach to traumatic emotional experiences was then selected for treatment, and illustrates how combat in Afghanistan shattered this soldier's world and self experience. Therapeutic action arises from this intersubjective perspective by providing a relational home so that unendurable emotions can be borne, processed, and integrated to achieve a more constant and individualized sense of self. Being a two-person model of therapy, the author also describes how his work with this traumatized soldier affected him, ultimately contributing to his own sense of authentic existing. The author discusses the need for therapists to recognize and acknowledge to traumatized patients their shared finitude and the ubiquity of trauma. In the Postscript, the patient describes what he felt was therapeutic and contrasts this to his previous experiences with manualized cognitive processing therapy.

Kim, Eui Jong; Ryu, Kyung Nam; Ahn, Jin Whan; Yoon, Yup

1994-01-01

The objective of the study was to evaluate the characteristic findings in tears of the anterior cruciate ligament(ACL) and associated injury at MR imaging. We reviewed the findings of MR images and the corresponding arthroscopic results of 32 patients with ACL tears. We evaluated the signal intensity and contour of ACL surrounding bony structures, menisci and associated injury of the knee joint. Complete ACL tears were present in 25 patients and partial ACL tears were in 7 patients. Complete ACL tears showed heterogenously increased signal intensity with contour bulging of the ACL in 14 patients (56%) and without bulging or absence in 11 patients(44%). Most patients torn ACL with contour bulging(12/14) had bone bruise, but only one patient torn ACL without bulging contour had bone bruise. ACL with thin continuous low signal band surrounding heterogenously increased signal intensity suggests partial tear which was seen in three patients of seven proved partial ACL tears. Combined bone injury in ACL tear were in 23 patients (73%) and most of these(22/23) were at midportion of lateral notch of femur and/or posterior portion of lateral tibial plateu. Deepening of lateral notch of femur were noted in 17 patients(53%). Associated injuries of the other ligaments of knee joint were buckling of the posterior cruciate ligament(16/32, 50%) and tears of the medial collateral ligament(11/32, 34%). Posterior horns of menisci were more frequent site of combined injury within menisci in patients with ACL tear. Acute tearing of ACL in MRI is seen as heterogenously increased signal intensity with contour bulging of ACL and combined bone bruises. Patients with torn ACL frequently have various combined injury. In patient with knee injury, these associated or ancillary findings suggest that ACL tear is present

To determine the frequency of anterolateral ligament (ALL) injury in patients with acute anterior cruciate ligament (ACL) rupture and to analyse its associated injury patterns. Ninety patients with acute ACL rupture for which MRI was obtained within 8 weeks after the initial trauma were retrospectively identified. Two radiologists assessed the status of the ALL on MRI by consensus. The presence or absence of an ALL abnormality was compared with the existence of medial and lateral meniscal tears diagnosed during arthroscopy. Associated collateral ligament and osseous injuries were documented with MRI. Forty-one of 90 knees (46 %) demonstrated ALL abnormalities on MRI. Of 49 knees with intact ALL, 15 (31 %) had a torn lateral meniscus as compared to 25 torn lateral menisci in 41 knees (61 %) with abnormal ALL (p = 0.008). Collateral ligament (p ≤ 0.05) and osseous injuries (p = 0.0037) were more frequent and severe in ALL-injured as compared with ALL-intact knees. ALL injuries are fairly common in patients with acute ACL rupture and are statistically significantly associated with lateral meniscal, collateral ligament and osseous injuries. (orig.)

Partial tearing of the anterior cruciate ligament: diagnosis and treatment

Directory of Open Access Journals (Sweden)

Eduardo Frois Temponi

2015-02-01

Full Text Available Partial tears of the anterior cruciate ligament (ACL are common and represent 10-27% of the total. The main reasons for attending to cases of non-torn bundles are biomechanical, vascular and proprioceptive. Continued presence of the bundle also serves as protection during the healing process. There is controversy regarding the definition of these injuries, which is based on anatomy, clinical examination, translation measurements, imaging examinations and arthroscopy. The way in which it is treated will depend on the existing laxity and instability. Conservative treatment is optional for cases without instability, with a focus on motor rehabilitation. Surgical treatment is a challenge, since it requires correct positioning of the bone tunnels and conservation of the remnants of the torn bundle. The pivot shift test under anesthesia, the magnetic resonance findings, the previous level and type of sports activity and the arthroscopic appearance and mechanical properties of the remnants will aid the orthopedist in the decision-making process between conservative treatment, surgical treatment with strengthening of the native ACL (selective reconstruction and classical (anatomical reconstruction.

To describe the pathological appearance of the anterolateral ligament (ALL) on US and MRI in knees with an anterior cruciate ligament (ACL) tear. This prospective study included 30 patients who had a suspected acute ACL tear. Their injured and contralateral knees were evaluated with radiography, US and MRI. Two radiologists evaluated the ALL on the MRI and US examinations. Agreement between these examiners' findings was evaluated with Cohen's kappa. On US examination, the ALL was found to be injured in 63% of cases (19/30; k = 0.93). The enthesis was found to be torn in 50% of cases (15/30; k = 1), with the tear located at the tibial attachment in all instances. On the MRI exam, the ALL was found to be injured in 53% of cases (16/30; k = 0.93). The enthesis was found to be torn in 13% of cases (4/30; k = 0.76), with the tear located at the tibial attachment in all instances (k = 0.93). ALL injuries that occur with ACL tears are located at the tibial enthesis. They are often associated with bone avulsion at the enthesis and are better viewed on US. (orig.)

Management of acute unstable acromioclavicular joint injuries.

Science.gov (United States)

Cisneros, Luis Natera; Reiriz, Juan Sarasquete

2016-12-01

Surgical management of acute unstable acromioclavicular joint injuries should be focused on realigning the torn ends of the ligaments to allow for healing potential. The most widely utilized treatment methods incorporate the use of metal hardware, which can alter the biomechanics of the acromioclavicular joint. This leads to a second surgical procedure for hardware removal once the ligaments have healed. Patients with unstable acromioclavicular joint injuries managed with arthroscopy-assisted procedures have shown good and excellent clinical outcomes, without the need for a second operation. These procedures incorporate a coracoclavicular suspension device aimed to function as an internal brace, narrowing the coracoclavicular space thus allowing for healing of the torn coracoclavicular ligaments. The lesser morbidity of a minimally invasive approach and the possibility to diagnose and treat concomitant intraarticular injuries; no obligatory implant removal, and the possibility of having a straight visualization of the inferior aspect of the base of the coracoid (convenient when placing coracoclavicular fixation systems) are the main advantages of the arthroscopic approach over classic open procedures. This article consists on a narrative review of the literature in regard to the management of acute acromioclavicular joint instability.

Finite Element Modelling of a Novel Anterior Cruciate Ligament Repairing Device

Directory of Open Access Journals (Sweden)

A.Vairis

2014-07-01

Full Text Available The knee anterior cruciate ligament which connects the femur to the tibia is often torn during sudden twisting motions resulting in knee instability with surgery being an effective treatment where the torn ligament is replaced with a graft. This study provides qualitative stress information on a restored knee which has been repaired using a novel device. This device has been designed to reduce graft damage and to minimize post-surgery complications. The device as well as the intact knee have been modelled in 3D and studied using finite elements to assess the mechanical behaviour of the device under different loads. Results are evaluated and compared to equivalent published works. They showed that high stresses appear where tendons wrap around objects like the securing pin of the knee ligament repair device, while the highest stresses are away from the repair device components indicating that the device design does not affect the graft. Developed stresses were within the tendon elastic range, and load case direction does not affect significantly the developed stresses on the circumference of tendons in the most stressed region.

While the past decades were marked by an increased interest for the existential situation of man suffering from disease, the mechanisms alienating the patient from himself and from his context have been poorly investigated. These mechanisms, though operating in a dynamic interaction, will be discussed here sequentially. The first part of this article focuses on individual mechanisms of alienation emerging from the relationship the patient establishes with his body and psyche and on those related to his relational context. The aim is not to comprehensively describe these phenomena, but to discuss--based on clinical vignettes--some examples and their implications. The second part of the article describes some mechanisms of alienation that are incorporated in the medical apparatus and the dominant discourses.

To determine the ability of 3.0T magnetic resonance (MR) imaging to identify partial tears of the anterior cruciate ligament (ACL) and to allow distinction of complete from partial ACL tears. One hundred seventy-two patients were prospectively studied by 3.0T MR imaging and arthroscopy in our institution. MR images were interpreted in consensus by two experienced reviewers, and the ACL was diagnosed as being normal, partially torn, or completely torn. Diagnostic accuracy of 3.0T MR for the detection of both complete and partial tears of the ACL was calculated using arthroscopy as the standard of reference. There were 132 patients with an intact ACL, 17 had a partial, and 23 had a complete tear of the ACL seen at arthroscopy. Sensitivity, specificity, and accuracy of 3.0T MR for complete ACL tears were 83, 99, and 97%, respectively, and, for partial ACL tears, 77, 97, and 95%, respectively. Five of 40 ACL lesions (13%) could not correctly be identified as complete or partial ACL tears. MR imaging at 3.0T represents a highly accurate method for identifying tears of the ACL. However, differentiation between complete and partial ACL tears and identification of partial tears of this ligament remains difficult, even at 3.0T. (orig.)

1996-03-01

The optimal treatment for concurrent injuries to the medial collateral and anterior cruciate ligaments has not been determined, despite numerous clinical and laboratory studies. The objective of this study was to examine the effect of surgical repair of the medial collateral ligament on its biomechanical and biochemical properties 52 weeks after such injuries. In the left knee of 12 skeletally mature New Zealand White rabbits, the medial collateral ligament was torn and the anterior cruciate ligament was transected and then reconstructed. This is an experimental model previously developed in our laboratory. In six rabbits, the torn ends of the medial collateral ligament were repaired, and in the remaining six rabbits, the ligament was not repaired. Fifty-two weeks after injury, we examined varus-valgus and anterior-posterior knee stability; structural properties of the femur-medial collateral ligament-tibia complex; and mechanical properties, collagen content, and mature collagen crosslinking of the medial collateral ligament. We could not detect significant differences between repair and nonrepair groups for any biomechanical or biochemical property. Our data support clinical findings that when the medial collateral and anterior cruciate ligaments are injured concurrently and the anterior cruciate ligament is reconstructed, conservative treatment of the ruptured medial collateral ligament can result in successful healing.

Document reconstruction by layout analysis of snippets

Kleber, Florian; Diem, Markus; Sablatnig, Robert

2010-02-01

Document analysis is done to analyze entire forms (e.g. intelligent form analysis, table detection) or to describe the layout/structure of a document. Also skew detection of scanned documents is performed to support OCR algorithms that are sensitive to skew. In this paper document analysis is applied to snippets of torn documents to calculate features for the reconstruction. Documents can either be destroyed by the intention to make the printed content unavailable (e.g. tax fraud investigation, business crime) or due to time induced degeneration of ancient documents (e.g. bad storage conditions). Current reconstruction methods for manually torn documents deal with the shape, inpainting and texture synthesis techniques. In this paper the possibility of document analysis techniques of snippets to support the matching algorithm by considering additional features are shown. This implies a rotational analysis, a color analysis and a line detection. As a future work it is planned to extend the feature set with the paper type (blank, checked, lined), the type of the writing (handwritten vs. machine printed) and the text layout of a snippet (text size, line spacing). Preliminary results show that these pre-processing steps can be performed reliably on a real dataset consisting of 690 snippets.

Determinants of Children's Mental Health in War-Torn Settings: Translating Research Into Action.

Science.gov (United States)

Miller, Kenneth E; Jordans, Mark J D

2016-06-01

Research on the mental health and psychosocial wellbeing of children in conflict-affected settings has undergone a significant paradigm shift in recent years. Earlier studies based on a war exposure model primarily emphasized the effects of direct exposure to armed conflict; this has gradually given way to a broader understanding of the diverse pathways by which organized violence affects children. A robustly supported comprehensive model includes risk factors at multiple points in time (prior war exposure, ongoing daily stressors) and at all levels of the social ecology. In particular, findings suggest that material deprivation and a set of family variables, including harsh parenting, parental distress, and witnessing intimate partner violence, are important mediators of the relationship between armed conflict and children's wellbeing. To date, however, interventions aimed at supporting war-affected children's wellbeing, both preventive and treatment-focused, have focused primarily on direct work with children, while paying only modest attention to ongoing risk factors in their families and broader environments. Possible reasons for the ongoing prioritization of child-focused interventions are considered, and examples are provided of recent evidence-based interventions that have reduced toxic stressors (harsh parenting and the use of violent discipline by teachers) in conflict-affected communities.

Rapid Deployment of International Tele-Intensive Care Unit Services in War-Torn Syria.

The conflict in Syria has created the largest humanitarian emergency of the twenty-first century. The 4-year Syrian conflict has destroyed hospitals and severely reduced the capacity of intensive care units (ICUs) and on-site intensivists. The crisis has triggered attempts from abroad to support the medical care of severely injured and acutely ill civilians inside Syria, including application of telemedicine. Within the United States, tele-ICU programs have been operating for more than a decade, albeit with high start-up costs and generally long development times. With the benefit of lessons drawn from those domestic models, the Syria Tele-ICU program was launched in December 2012 to manage the care of ICU patients in parts of Syria by using inexpensive, off-the-shelf video cameras, free social media applications, and a volunteer network of Arabic-speaking intensivists in North America and Europe. Within 1 year, 90 patients per month in three ICUs were receiving tele-ICU services. At the end of 2015, a network of approximately 20 participating intensivists was providing clinical decision support 24 hours per day to five civilian ICUs in Syria. The volunteer clinicians manage patients at a distance of more than 6,000 miles, separated by seven or eight time zones between North America and Syria. The program is implementing a cloud-based electronic medical record for physician documentation and a medication administration record for nurses. There are virtual chat rooms for patient rounds, radiology review, and trainee teaching. The early success of the program shows how a small number of committed physicians can use inexpensive equipment spawned by the Internet revolution to support from afar civilian health care delivery in a high-conflict country.

With the benefit of lessons drawn from those domestic models, the Syria Tele-ICU program was launched in December 2012 to manage the care of ICU patients in parts of Syria by using inexpensive, off-the-shelf video cameras, free social media applications, and a volunteer network of Arabic-speaking intensivists in North America and Europe. Within 1 year, 90 patients per month in three ICUs were receiving tele-ICU services. At the end of 2015, a network of approximately 20 participating intensivists was providing clinical decision support 24 hours per day to five civilian ICUs in Syria. The volunteer clinicians manage patients at a distance of more than 6,000 miles, separated by seven or eight time zones between North America and Syria. The program is implementing a cloud-based electronic medical record for physician documentation and a medication administration record for nurses. There are virtual chat rooms for patient rounds, radiology review, and trainee teaching. The early success of the program shows how a small number of committed physicians can use inexpensive equipment spawned by the Internet revolution to support from afar civilian health care delivery in a high-conflict country.

Pfitzner, Elvira

By means of a small watercolor, painted by a musicologist, the existence of the highschool observatory of Chemnitz was rediscovered. The small observatory was build in 1893 by means of funds and a donation: after WW I it was also used for popular education. During Nazi times, the observatory fell into neglect, and the mechanical damage made it impossible to put it back into operation after WW II The building was torn down in 1964 and forgotten.

Phantom energy accretion onto black holes in a cyclic universe

Black holes pose a serious problem in cyclic or oscillating cosmology. It is speculated that, in the cyclic universe with phantom turnarounds, black holes will be torn apart by phantom energy prior to turnaround before they can create any problems. In this paper, using the mechanism of phantom accretion onto black holes, we find that black holes do not disappear before phantom turnaround. But the remanent black holes will not cause any problems due to Hawking evaporation.

Residents in localities throughout the world voluntarily participate in the routine recycling of household wastes, such as paper, metals, and plastics containers. But when a house in their neighborhood gets built or torn down, most of the debris – including wood waste – gets landfilled. Such a waste of material suggests that there are opportunities to add value to these under-utilized resources. The great variability, as well as contamination, pose major challenges. It is recommended that rec...

Vertical tears of the cranial horn of the meniscus and its cranial ligament in the equine femorotibial joint: 7 cases and their treatment by arthroscopic surgery.

Science.gov (United States)

Walmsley, J P

1995-01-01

Five horses with a vertical tear in the cranial horn and cranial ligament of the medial meniscus and 2 horses with a similar injury in the lateral meniscus were diagnosed from a series of 126 horses which were examined arthroscopically for stifle lameness. All the lesions had similar characteristics. The tear was about 1 cm from the axial border of the meniscus and its ligament and, in all but one case in which it was incomplete, much of the torn tissue was loosely attached in the axial part of the joint from where it was removed. The remaining meniscus, abaxial to the tear, was displaced cranially and abaxially and its torn edges were debrided. Radiographically, 6 cases had proliferative new bone on the cranial aspect of the intercondylar eminence of the tibia and 3 had calcified soft tissue densities in the cranial, medial or lateral femorotibial joint. Following surgery and a 6 month period of rest and controlled exercise, 3 horses returned to full competition work, one was usable for hacking, 2 are convalescing and one is lame after one year. It is postulated that this could be a characteristic meniscal injury in horses which can benefit from arthroscopic surgery. Better techniques for accessing the body and caudal pole of the menisci are needed if a more complete diagnosis and treatment of meniscal injuries are to be achieved.

To determine the normal anatomic relationships of Hoffa's fat pad with the anterior cruciate ligament (ACL) and with the frequency of Hoffa's fat pad abnormalities in ACL-deficient knees. Retrospective clinical study on patients and observational anatomic study on cadavers. The study was approved by the Institutional Review Board. MR imaging studies of the knees of 100 patients (21-48 years old) with or without arthroscopically proven tears of the ACL, performed at a single institution, were reviewed by two readers for abnormalities of Hoffa's fat pad. Ten cadaveric knee specimens were studied with MR imaging and Faxitron radiographs, and by inspection of sections and histology. Alterations in Hoffa's fat pad on MR imaging were present in 64% (32/50) of patients with torn ACLs, and in 24% (12/50) of patients without a tear of the ACL (P < 0.05). Hoffa's fat pad inserted into the intercondylar notch in 50% (5/10) of cadaveric specimens, four in conjunction with the ligamentum mucosum and in one in an isolated fashion. Histological study demonstrated the composition of the ligamentum mucosum and Hoffa's fat pad and their course and insertion sites in the intercondylar notch. Abnormalities of Hoffa's fat pad, such as focal and diffuse edema, tears, scars and synovial proliferation, are more common in knees with torn ACLs than in knees with intact ACLs. (orig.)

The immunization card is revised with addition of general information about child health and is later called as child health card. This card is a tool used by Health Management Information System in Nepal. It is important for tracking the records of immunization. Aim is to identify the factors determining the availability, utilization and retention of the child health card in Western Nepal. A cross sectional study was conducted among mothers having children education. Retention of the card was found to be 82.2%. 90.3% retention was seen among 0-12 months children age group whereas it was 74 % among12 to 24 months age group. The reasons for less retention were torn by the child/played by child (54.6%) followed by lack of proper place,unaware about importance and poor quality of card.The new child health cards were insufficient, compelling use of both new and old cards which created problem in consistency. Regarding utilization of child health card, it was found to be used for birth registration and for further studies in abroad. The areas of utilization of child health card should be broadened so that the retention of card can be increased. The main reasons for less retention of the card are torn by children and lack of the proper place.

Full Text Available The objective of the article is to present the internal and external model of management and how it is connected to the political system and national culture among the Visegrad countries.  The  paper  presents  several  examples  of  transitive models of management. It aims to indicate which advantages and disadvantages can be  identified  in  the  transitive  groups,  how  they  can  influences  the  international investment potential and image of the company. Qualitative research on asample of Polish, German and Ukrainian companies combined with secondary data. Polish business culture can be regarded as transitive –the influence of two bordering civilization (Western and Orthodox is noticeable. This phenomenon has shaped the business values and it is still present in the international context. The  transitive  business  model  of  management allows  to  predict  and  avoid  the  problems  occurring  in  the  internal  and  external relationships  in  the  companies  from  Central  Europe  who  are  involved  into international projects. The  paper  enables  the  clarification  of  the  transitive management  culture;  the  juxtaposition  of  differences  and  similarities  and  their impacts  of  the  internal  and  external  business  relationships;  the  explicitness  of dichotomy and its influence on international business image of Visegrad countries.

Sexual violence toward children and youth in war-torn eastern Democratic Republic of Congo.

Directory of Open Access Journals (Sweden)

Luc Malemo Kalisya

Full Text Available BACKGROUND: The epidemic of gender-based violence in the Democratic Republic of the Congo (DRC has garnered popular media attention, but is incompletely described in the medical literature to date. In particular, the relative importance of militarized compared to civilian rape and the impact on vulnerable populations merits further study. We describe a retrospective case series of sexual abuse among children and youth in eastern DRC. METHODS: Medical records of patients treated for sexual assault at HEAL Africa Hospital, Goma, DRC between 2006 and 2008 were reviewed. Information extracted from the chart record was summarized using descriptive statistics, with comparative statistics to examine differences between pediatric (≤ 18 yrs and adult patients. FINDINGS: 440 pediatric and 54 adult sexual abuse cases were identified. Children and youth were more often assaulted by someone known to the family (74% vs 30%, OR 6.7 [95%CI 3.6-12], p72 hours after the assault was more common in pediatric patients (53% vs 33%, OR 2.2 [95%CI 1.2-4.0], p = 0.007. Physical signs of sexual abuse, including lesions of the posterior fourchette, hymeneal tears, and anal lesions, were more commonly observed in children and youth (84% vs 69%, OR 2.3 [95%CI 1.3-4.4], p = 0.006. Nine (2.9% pediatrics patients were HIV-positive at presentation, compared to 5.3% of adults (p = 0.34. INTERPRETATION: World media attention has focused on violent rape as a weapon of war in the DRC. Our data highlight some neglected but important and distinct aspects of the ongoing epidemic of sexual violence: sexual abuse of children and youth.

Torn ACL: A New Bioengineered Substitute Brought from the Laboratory to the Knee Joint

Directory of Open Access Journals (Sweden)

Francine Goulet

2004-01-01

Full Text Available Anterior cruciate ligament (ACL injuries occur at an annual rate of 120 000 in the USA, and many need reconstructive surgery. We report successful results at 1–13 months following implantation of bioengineered ACL (bACL in goats. A bACL has been developed using autologous ACL cells, a collagen matrix and bone plugs. The extremities of the bACL were fully integrated into the femur and tibia of the host. Vascularisation of the grafts was extensive 1 month post-surgery and improved with time. At 6 months post-grafting, histological and ultrastructural observations demonstrated a highly organised ligamentous structure, rich in type I collagen fibres and fibroblasts. At the implants' insertion sites, characteristic fibrocartilage was observed having well aligned chondrocytes and collagen fibrils. After a year, mechanical rupture of the grafts demonstrated a major gain in strength. Eventual applications of this new technology in humans include multiple uses in orthopaedic, dental and reconstructive surgeries.

Displacement of a portion of the torn anterior cruciate ligament (ACL) into the intercondylar notch can cause a focal fibrotic reaction similar to that seen following ACL reconstruction. This displacement, which can result in locking or limitation of knee extension, is termed stump entrapment and is described in adult MR imaging literature. We present a pictorial essay of the etiology and appearance of stump entrapment on MR imaging of the knee in an older child and adolescents and review the significance of this finding. (orig.)

Our objectives were to determine retrospectively the prevalence, patients' demographics, mechanism of injury, combination of torn ligaments, associated intra-articular and extra-articular injuries, fractures, bone bruises, femoral-tibial alignment and neurovascular complications of knee dislocations as evaluated by magnetic resonance (MR) imaging. From 17,698 consecutive knee examinations by magnetic resonance imaging (MRI) over a 6-year period, 20 patients with knee dislocations were identified. The medical records of these patients were subsequently reviewed for relevant clinical history, management and operative findings. The prevalence of knee dislocations was 0.11% [95% confidence interval (95% CI) 0.06-0.16]. There were 16 male patients and four female patients, with ages ranging from 15 years to 76 years (mean 31 years). Fifteen patients had low-velocity injuries (75%), of which 11 were amateur sports related and four were from falls. Four patients (20%) had suffered high-velocity trauma (motor vehicle accidents). One patient had no history available. Anatomic alignment was present at imaging in 16 patients (80%). Eighteen patients had three-ligament tears, two had four-ligament tears. The four-ligament tears occurred with low-velocity injuries. The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) were torn in every patient; the lateral collateral ligament (LCL) was torn in 50%, and the medial collateral ligament (MCL) in 60%. Intra-articular injuries included meniscal tears (five in four patients), fractures (eight in seven patients), bone bruises (15 patients), and patellar retinaculum tears (eight partial, two complete). The most common extra-articular injury was a complete biceps femoris tendon tear (five, 25%). There were two popliteal tendon tears and one iliotibial band tear. One patient had received a vascular injury following a motor vehicle accident (MVA) and had been treated prior to undergoing MRI. Bone bruises

Otoliths from juvenile whitefish were therefore collected from freshwater ponds at 5 hatcheries, from adult whitefish from 6 spawning sites at sea along the Finnish west coast, and from adult whitefish ascending to spawn in the Torne River, in total 67 otoliths. PIXE was applied to determine the elemental concentrations in these otoliths. While otoliths from the juveniles raised in the freshwater ponds showed low but varying strontium concentrations (194-1664 μg/g,), otoliths from sea-spawning fish showed high uniform strontium levels (3720-4333 μg/g). The otolith core analysis of whitefish from Torne River showed large variations in the strontium concentrations (1525-3650 μg/g). These otolith data form a database to be used for provenance studies of wild adult whitefish caught at sea. The applicability of the database was evaluated by analyzing the core of polished otoliths from 11 whitefish from a test site at sea in the Larsmo archipelago. Our results show that by analyzing strontium in the otolith core, we can differentiate between hatchery-origin and wild-origin whitefish, but not always between river and sea spawning whitefish.

Failure of rotator cuff healing is a common complication despite the rapid development of surgical repair techniques for the torn rotator cuff. To verify the effect of atelocollagen on tendon-to-bone healing in the rabbit supraspinatus tendon compared with conventional cuff repair. Controlled laboratory study. A tear of the supraspinatus tendon was created and repaired in 46 New Zealand White rabbits. They were then randomly allocated into 2 groups (23 rabbits per group; 15 for histological and 8 for biomechanical test). In the experimental group, patch-type atelocollagen was implanted between bone and tendon during repair; in the control group, the torn tendon was repaired without atelocollagen. Each opposite shoulder served as a sham (tendon was exposed only). Histological evaluation was performed at 4, 8, and 12 weeks. Biomechanical tensile strength was tested 12 weeks after surgery. Histological evaluation scores of the experimental group (4.0 ± 1.0) were significantly superior to those of the control group (7.7 ± 2.7) at 12 weeks ( P = .005). The load to failure was significantly higher in the experimental group (51.4 ± 3.9 N) than in the control group (36.4 ± 5.9 N) ( P = .001). Histological and biomechanical studies demonstrated better results in the experimental group using atelocollagen in a rabbit model of the supraspinatus tendon tear. Atelocollagen patch could be used in the cuff repair site to enhance healing.

The aim of this study was to determine whether early MRI after anterior cruciate ligament (ACL) injury can predict the morphological recovery of the torn ACL treated by early protective motion. Consecutive acute ruptures of the ACL in 35 patients (mean age; 27.2 years) who were allowed to be healed without surgery were evaluated by repeated MRI. MR images were compared for a few days after injury (initial MRI), approximately one month after treatment (second MRI), and at an average follow-up of 8.5 months (follow-up MRI). The average time from injury to the initial MRI was 7.3 days. The initial MR appearance of the torn ligament was classified into five types of visualized ligament contours. The emergence of restoration signs such as straight band and/or verticalization was examined in the second MRI. The follow-up MR appearance of the treated ACL was categorized into four grades depending on homogeneity, straight band, and size. Relationships between the initial MRI and the follow-up MRI, the restoration signs on the second MRI and the follow-up MRI were analyzed using the Spearman rank correlation coefficient. As a result, the contour of the initial MRI was found to correlate with morphological recovery on the follow-up MRI (r s =0.565, p<0.001). There was no correlation between the emergence of restoration signs on the second MRI and morphological recovery on the follow-up MRI. (author)

Fifty adult sports medicine patients with anterior knee pain and other clinical findings of chondromalacia patellae unresponsive to more than 3 months of conservative therapy were evaluated with bone scintigraphy with subsequent arthroscopic correlation. There was significant correlation (Sperman rank correlation = .545, P < .001) between the intensity of increased patellar scintigraphic activity and the Metcalf grade of chondromalacia seen at arthroscopy. Bone scintigraphy also disclosed clinically unsuspected torn menisci. Bone scintigraphy contributes to accurate diagnostic evaluation and appropriate surgical planning for adult sports medicine patients with chronic anterior knee pain

Thirty patients were examined with CT of the menisci. All findings were confirmed by arthroscopy. One false positive diagnosis of a torn meniscus was made, caused by partial volume effect. In seven patients with irregular degenerative changes of the menisci, the abnormality could be clearly demonstrated. One meniscus ganglion was shown. Seven meniscus lesions, which were not shown by arthrography or arthroscopy, were clearly demonstrated by CT. The computer tomographic demonstration of menisci can replace knee arthrography as the examination of choice and should be performed before carrying out arthroscopy. (orig.) [de

Morel-Lavallee lesion is a closed degloving soft tissue injury in which subcutaneous tissue is torn from the underlying muscular fascia. The tear leads to venolymphatic leak, and concomitant adipose tissue necrosis from the force of the trauma causes swelling and possible infection at the site of injury. The traditional treatment for the lesion is surgical drainage and debridement. In this report, an endoscopic method is described, which achieves the goal of an open surgical debridement but minimizes surgical morbidity. Copyright © 2016 Elsevier Ltd. All rights reserved.

Feeding ecology of a nocturnal invasive alien lizard species, Hemidactylus mabouia Moreau de Jonnès, 1818 (Gekkonidae, living in an outcrop rocky area in southeastern Brazil

Directory of Open Access Journals (Sweden)

Full Text Available We studied in fieldwork, the feeding ecology of a Hemidactylus mabouia population from southeastern Brazil throughout one year in a region with marked climatic seasonality. A sampling of availability of arthropods in the environment was carried out, which evidenced that the availability of food resources influenced the composition of the diet of H. mabouia. There were no seasonal differences on diet composition, which may be due to the relatively constant availability on prey throughout the year. In general, this population can be classified as generalist and opportunistic regarding diet. There was a high food niche overlap among juveniles and adults, although juvenile lizards tend to eat higer number of prey (but in lower volume when compared to adult lizards. The ability to exploit a wide array of prey in an efficient way, maintaining a positive energetic balance, may be a factor determining the efficiency of this exotic species to occupy invaded areas.

Torn between war and peace: Critiquing the use of war to mobilize peaceful climate action

International Nuclear Information System (INIS)

Kester, Johannes; Sovacool, Benjamin K.

2017-01-01

Notable studies have suggested the potentiality of the WWII wartime mobilization as a model for climate change adaptation and/or mitigation. The argument being that we need a similar rapid and total shift in our industrial social and economic environment to prevent or at least address the pending impacts of climate change. This argument and these studies have inspired us to think with them on what it means to use the WWII war analogy as a security claim in energy and climate change debates. Here, we would like to use this opportunity to draw attention to some of the implicit dangers of a call to war in such discussions. Among others we observe, first, the absence of any attention to the actual mobilization policies, in terms of garnishing public support. Second, based on the insights from Critical Security Studies, we question the historical incongruence of the case study especially by comparing the perceived enemy in both cases. Lastly, building on that same security literature, we point to some undesirable and perhaps unintended consequences of the use of war analogies in climate change debates. - Highlights: • The WWII war analogy with its policy focus extends the war metaphor in climate change debates. • As a mobilization technique the analogy draws attention to the WWII policies that “sold” the war. • We provide several reasons why the war analogy is incongruent with climate change. • The war analogy remains subject to the dangers that accompany the use of a war metaphor.

Rotator cuff tears (RCTs) are a common shoulder problem in the elderly that can lead to both muscle atrophy and fatty infiltration due to less physical load. Satellite cells, quiescent cells under the basal lamina of skeletal muscle fibers, play a major role in muscle regeneration. However, the myogenic potency of human satellite cells in muscles with fatty infiltration is unclear due to the difficulty in isolating from small samples, and the mechanism of the progression of fatty infiltration has not been elucidated. The purpose of this study was to analyze the population of myogenic and adipogenic cells in disused supraspinatus (SSP) and intact subscapularis (SSC) muscles of the RCTs from the same patients using fluorescence-activated cell sorting. The microstructure of the muscle with fatty infiltration was observed as a whole mount condition under multi-photon microscopy. Myogenic differentiation potential and gene expression were evaluated in satellite cells. The results showed that the SSP muscle with greater fatty infiltration surrounded by collagen fibers compared with the SSC muscle under multi-photon microscopy. A positive correlation was observed between the ratio of muscle volume to fat volume and the ratio of myogenic precursor to adipogenic precursor. Although no difference was observed in the myogenic potential between the two groups in cell culture, satellite cells in the disused SSP muscle showed higher intrinsic myogenic gene expression than those in the intact SSC muscle. Our results indicate that satellite cells from the disused SSP retain sufficient potential of muscle growth despite the fatty infiltration.

Surgical revirgination: Four vaginal mucosal flaps for reconstruction of a hymen

Directory of Open Access Journals (Sweden)

Hemant A Saraiya

2015-01-01

Full Text Available Introduction: Over centuries, virginity has been given social, religious and moral importance. It is widely believed as a state of a female who has never engaged in sexual intercourse, and her hymen is intact. Hymenoplasty for torn hymen is carried out not only for the sake of cultural and religious traditions but also for the social status and interpersonal relationships. Materials and Methods: 2.5 cm long and 1 cm wide four vaginal mucosal flaps were raised from the anterior vaginal wall just behind labia minora. Two flaps were based proximally, and their two opposing flaps were based distally. These flaps were overlapped in a crisscross fashion and were sutured with 5/0 Polyglactin (Vicryl® sutures leaving no area raw. The donor area was closed primarily. When some remains of a torn hymen were found, one to three vaginal mucosal flaps were added to its remains as per the need for reconstruction. Results: We operated upon 11 patients. In nine cases, the hymen was reconstructed with four flaps. In remaining two, it was reconstructed from the remains using vaginal mucosal flaps. All flaps healed without any infection or disruption. Sutures got absorbed in 25-35 days. In all cases, this newly constructed barrier broke with only moderate pressure at the time of penetrative sex serving the purpose of the surgery completely. Conclusion: Erasing evidence of the sexual history simply by ′Surgical Revirgination′ is extremely important to women contemplating marriage in cultures where a high value is placed on virginity.

Reconstruction versus conservative treatment after rupture of the anterior cruciate ligament: cost effectiveness analysis

Directory of Open Access Journals (Sweden)

Farshad Mazda

2011-11-01

Full Text Available Abstract Background The decision whether to treat conservatively or reconstruct surgically a torn anterior cruciate ligament (ACL is an ongoing subject of debate. The high prevalence and associated public health burden of torn ACL has led to continuous efforts to determine the best therapeutic approach. A critical evaluation of benefits and expenditures of both treatment options as in a cost effectiveness analysis seems well-suited to provide valuable information for treating physicians and healthcare policymakers. Methods A literature review identified four of 7410 searched articles providing sufficient outcome probabilities for the two treatment options for modeling. A transformation key based on the expert opinions of 25 orthopedic surgeons was used to derive utilities from available evidence. The cost data for both treatment strategies were based on average figures compiled by Orthopaedic University Hospital Balgrist and reinforced by Swiss national statistics. A decision tree was constructed to derive the cost-effectiveness of each strategy, which was then tested for robustness using Monte Carlo simulation. Results Decision tree analysis revealed a cost effectiveness of 16,038 USD/0.78 QALY for ACL reconstruction and 15,466 USD/0.66 QALY for conservative treatment, implying an incremental cost effectiveness of 4,890 USD/QALY for ACL reconstruction. Sensitivity analysis of utilities did not change the trend. Conclusion ACL reconstruction for reestablishment of knee stability seems cost effective in the Swiss setting based on currently available evidence. This, however, should be reinforced with randomized controlled trials comparing the two treatment strategies.

Amputation of finger by horse bite with complete avulsion of both flexor tendons.

Koren, Lior; Stahl, Shalom; Rovitsky, Alexey; Peled, Eli

Amputation of fingers with tendon avulsion occurs through a traction injury, and most occur through a ring avulsion mechanism. Usually the flexor digitorum profundus is torn out with the amputated finger. Replantation usually is recommended only when the amputation is distal to the flexor digitorum superficialis insertion. Animal bites are relatively common, with a decreasing order of frequency of dogs, cats, and humans. Horse bites are relatively infrequent but are associated with crush injuries and tissue loss when they occur. This article describes a 23-year-old man with amputation of his middle finger at the level of the proximal phalanx after being bitten by a horse. The amputated stump was avulsed with the middle finger flexor digitorum profundus and flexor digitorum superficialis torn from the muscle-tendon junction from approximately the middle of the forearm. The patient had no other injuries, and he was able to move his other 4 fingers with only mild pain. As the amputated digit was not suitable for replantation, the wound was irrigated and debrided. The edges of the phalanx were trimmed, and the edges of the wound were sutured. Tetanus toxoid and rabies vaccine were administered, along with intravenous amoxicillin and clavulanic acid. The patient was discharged from the hospital 2 days later, with no sign of infection of the wound or compartment syndrome of the forearm. This case demonstrates the weakest point in the myotendinous junction and emphasizes the importance of a careful physical examination in patients with a traumatic amputation.

To demonstrate the magnetic resonance imaging (MRI) findings of double-bundle (DB) anterior cruciate ligament (ACL) reconstruction grafts. Sixty-six patients with DB ACL reconstruction were evaluated with MRI 2 years postoperatively. Graft thickness was measured separately by two musculoskeletal radiologists. The MRI findings of graft disruption, signal intensity (SI) changes, cystic degeneration, arthrofibrosis, and impingement were analyzed. The statistical significance of the association between MRI findings was calculated. The mean anteromedial (AM) graft thickness was reduced 9% and the mean posterolateral (PL) graft thickness was reduced 18% from the original graft thickness. Disruption was seen in 3% of AM grafts and 6% of PL grafts and a partial tear in 8 and 23%, respectively. Both grafts were disrupted in 3% of patients. Increased SI was seen in 14% of intact AM grafts and in 60% of partially torn AM grafts (p = 0.032). In PL grafts the increased SI was seen in 51% of the intact grafts and in 93% of the partially torn grafts (p = 0.005). Cystic degeneration was seen in 8% of AM grafts and in 5% of PL grafts. Diffuse arthrofibrosis was seen in 5% of patients and a localized cyclops lesion in 3% of patients. Impingement of the AM graft was seen in 8% of patients. Both grafts were disrupted in 3% of patients. Also, the frequencies of other complications were low. The use of orthogonal sequences in the evaluation of the PL graft SI seems to cause volume-averaging artefacts. (orig.)

The objective of our study was to relate alterations in biceps tendon diameter and signal on MR images to gross anatomy and histology. T1-weighted, T2-weighted fat-saturated, and proton density-weighted fat-saturated spin-echo sequences were acquired in 15 cadaveric shoulders. Biceps tendon diameter (normal, flattened, thickened, and partially or completely torn) and signal intensity (compared with bone, fat, muscle, and joint fluid) were graded by two readers independently and in a blinded fashion. The distance of tendon abnormalities from the attachment at the glenoid were noted in millimeters. MRI findings were related to gross anatomic and histologic findings. On the basis of gross anatomy, there were six normal, five flattened, two thickened, and two partially torn tendons. Reader 1 graded nine diameter changes correctly, missed two, and incorrectly graded four. The corresponding values for reader 2 were seven, one, and five, respectively, with kappa = 0.75. Histology showed mucoid degeneration (n = 13), lipoid degeneration (n = 7), and fatty infiltration (n = 6). At least one type of abnormality was found in each single tendon. Mucoid degeneration was hyperintense compared with fatty infiltration on T2-weighted fat-saturated images and hyperintense compared with magic-angle artifacts on proton density-weighted fat-saturated images. MRI-based localization of degeneration agreed well with histologic findings. Diameter changes are specific but not sensitive in diagnosing tendinopathy of the biceps tendon. Increased tendon signal is most typical for mucoid degeneration but should be used with care as a sign of tendon degeneration.

We herein report the case of a patient demonstrating a lung abscess with acute empyema which improved after performing pnemumonotomy and lung abscess drainage. A 60-year-old male was referred to our hospital to receive treatment for a lung abscess with acute empyema. At surgery, the lung parenchyma was slightly torn with pus leakage. After drainage of lung abscess by enlarging the injured part, curettage in the thoracic cavity and decortication were performed. The postoperative course was uneventful. Direct drainage of an abscess into the thoracic cavity is thought to be a choice for the treatment of lung abscesses.

Graphene is a semi-metallic, transparent, atomic crystal structure material which is promising for its high mobility, strength and transparency - potentially applicable for radio frequency (RF) circuitry and energy harvesting and storage applications. Uniform (same number of layers), continuous (not torn or discontinuous), large area (100 mm to 200 mm wafer scale), low-cost, reliable growth are the first hand challenges for its commercialization prospect. We show a time variant uniform (layer control) growth of bi- to multi-layer graphene using atmospheric chemical vapor deposition system. We use Raman spectroscopy for physical characterization supported by electrical property analysis. © 2013 IEEE.

The Poster As a Curatorial Challenge

DEFF Research Database (Denmark)

Christensen, Line Hjorth

This paper investigates the poster media from a curatorial perspective, focusing on the shift that occurs when posters are torn loose of their original living context and exhibited in museums. The shift is of a general museological relevance, however, is reinforced by posters’ distinct...... counterability to be a viable option for curatorial work. The concept is unfolded in a case study of a recent exhibition on British posters of the interwar years, held in 2015/16 at the Danish Poster Museum in the open air museum Den Gamle By in Aarhus, which I curated in collaboration with graphic designer...

Time variant layer control in atmospheric pressure chemical vapor deposition based growth of graphene

KAUST Repository

Qaisi, Ramy M.

2013-04-01

Graphene is a semi-metallic, transparent, atomic crystal structure material which is promising for its high mobility, strength and transparency - potentially applicable for radio frequency (RF) circuitry and energy harvesting and storage applications. Uniform (same number of layers), continuous (not torn or discontinuous), large area (100 mm to 200 mm wafer scale), low-cost, reliable growth are the first hand challenges for its commercialization prospect. We show a time variant uniform (layer control) growth of bi- to multi-layer graphene using atmospheric chemical vapor deposition system. We use Raman spectroscopy for physical characterization supported by electrical property analysis. © 2013 IEEE.

Detection Of Moisture In Commercial And Industrial Built-Up Roofing Systems

Sopko, Victor

1982-03-01

The roof has always been one of the most important portions of a building envelope. It is, however, one of the most overlooked areas with respect to building maintenance. As long as the roof is not leaking into the building, it is thought to be functioning properly. This is an erroneous assumption as many problems occur long before they are evident as leaks into the building. Early location and repair of roof problems can mean the difference between a roof which must be completely torn off and replaced and one which will give years of service to the building owner.

Combined Gravimetric-Seismic Crustal Model for Antarctica

Baranov, Alexey; Tenzer, Robert; Bagherbandi, Mohammad

2018-01-01

The latest seismic data and improved information about the subglacial bedrock relief are used in this study to estimate the sediment and crustal thickness under the Antarctic continent. Since large parts of Antarctica are not yet covered by seismic surveys, the gravity and crustal structure models are used to interpolate the Moho information where seismic data are missing. The gravity information is also extended offshore to detect the Moho under continental margins and neighboring oceanic crust. The processing strategy involves the solution to the Vening Meinesz-Moritz's inverse problem of isostasy constrained on seismic data. A comparison of our new results with existing studies indicates a substantial improvement in the sediment and crustal models. The seismic data analysis shows significant sediment accumulations in Antarctica, with broad sedimentary basins. According to our result, the maximum sediment thickness in Antarctica is about 15 km under Filchner-Ronne Ice Shelf. The Moho relief closely resembles major geological and tectonic features. A rather thick continental crust of East Antarctic Craton is separated from a complex geological/tectonic structure of West Antarctica by the Transantarctic Mountains. The average Moho depth of 34.1 km under the Antarctic continent slightly differs from previous estimates. A maximum Moho deepening of 58.2 km under the Gamburtsev Subglacial Mountains in East Antarctica confirmed the presence of deep and compact orogenic roots. Another large Moho depth in East Antarctica is detected under Dronning Maud Land with two orogenic roots under Wohlthat Massif (48-50 km) and the Kottas Mountains (48-50 km) that are separated by a relatively thin crust along Jutulstraumen Rift. The Moho depth under central parts of the Transantarctic Mountains reaches 46 km. The maximum Moho deepening (34-38 km) in West Antarctica is under the Antarctic Peninsula. The Moho depth minima in East Antarctica are found under the Lambert Trench (24

Full Text Available As one of the contemporary Iranian women writers living in the U.S, Goli Taraqqi’s fiction is mostly concerned with pains and difficulties of migrant Iranian women in other countries. Bearing a biographical resemblance, her sequence collection to Scattered Memories, entitled Two Worlds retells interrelated short stories of a woman writer narrator, entangled in an asylum in Paris, who digs into her past, writes stories about it, and is able to regain her sanity in the end, as she gets ready to enter the brave new world. The process of identity recognition is to be approached with an eye on Homi K, Bhabha’s assertions about ‘hybridity’ and ‘in-between’ as explained in his 1994 Location and Culture, to see to what degree the newly gained identity, which is resembled to a resurrection, is in fact a hybrid one.

Synovialisation of the torn anterior cruciate ligament of the knee: comparison between magnetic resonance and arthroscopy

International Nuclear Information System (INIS)

Higueras Guerrero, V.; Torregrosa Andres, A.; Marti-Bonmati, L.; Casillas, C.; Sanfeliu, M.

1999-01-01

The aim of this study was to assess the accuracy of MR in the diagnosis of synovialisation of the anterior cruciate ligament (ACL) compared with arthroscopy. One hundred and forty-nine patients were examined with MR imaging and arthroscopy of the knee. The MR sign used to consider a synovialised ACL consisted of hypointense fibrillar tracts, disrupted and wavily, in its expected course. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), comparison of proportions (McNemar test) and Kappa values for agreement between MR imaging and arthroscopy were calculated. Of the 133 (89.3 %) ligaments without synovialisation at arthroscopy, 130 accorded with the MR results. Of the 16 (10.7 %) synovialised ligaments, 13 accorded with the MR results. Three false-positive and three false-negative MR diagnoses were identified. The agreement between both techniques was excellent (Kappa = 0.79; p = 0.000), without differences (McNemar test; p = 1). Sensitivity was 0.81, specificity 0.98, PPV 0.98 and NPV 0.81. Magnetic resonance imaging is highly reliability for synovialisation diagnosis. The imaging sign used to diagnose synovialised ACL (hypointense comma-like tracts in its expected course) is reliable. As this reparative process can simulate an intact ligament, knowledge of this sign is important in diagnosing synovialisation of ACL tears so as not to confuse it with normal ACL. (orig.)

To evaluate the change in the thickness and width of the residual meniscus using magnetic resonance imaging (MRI) in patients who underwent arthroscopic partial meniscectomy for discoid lateral meniscus (DLM), to assess whether the degeneration of the articular cartilage in the lateral compartment of the knee progressed, and to evaluate clinical results. Among the patients who underwent arthroscopic partial meniscectomy for DLM between January 1997 and December 2011, those who were aged 40 or below at surgery were followed up for at least 3 years, and received at least 2 follow-up MRIs that were retrospectively reviewed. MRIs were done in symptomatic knees. Using MRI, the relative thickness and width were measured in the anterior horn, midportion, and posterior horn. To determine whether the degeneration of the lateral compartment would progress, the articular cartilage was graded based on the Outerbridge classification in MRIs. The clinical results were evaluated using the Lysholm score. A total of 20 patients (21 knees) were included. The average follow-up period was 6.8 years. In residual meniscus, the relative thickness of the midportion decreased from 9.0% ± 2.4% to 7.3% ± 2.3% (P meniscus. A progression of degeneration in the lateral compartment was observed. However, the clinical results did not present significant changes. In symptomatic patients after arthroscopic partial meniscectomy for DLM, the thickness and width of the residual meniscus decreases over time. The arthritic change of the lateral compartment of the knee progressed. However, the change in the size of the residual meniscus was of unknown clinical significance.

The Syrian crisis, now in its fifth year, has created an unprecedented strain on health services and systems due to the protracted nature of the warfare, the targeting of medics and health care infrastructure, the exodus of physicians and nurses, the shortage of medical supplies and medications, and the disruption of medical education and training. Within a few short years, the life expectancy of resident Syrians has declined by 20 years. Over the first 4 years of the conflict, more than 75,000 civilians died from injuries incurred in the violence. More than twice as many civilians, including many women and children, have died prematurely of infectious and noninfectious chronic diseases for want of adequate health care. Doctors, local administrators, and nongovernmental organizations are struggling to manage the consequences of the conflict under substandard conditions, often using unorthodox methods of health care delivery in field hospitals and remotely by telehealth communication. Much-needed medical supplies are channeled through dangerous routes across the borders from Lebanon, Jordan, and Turkey. Physicians in the United States and other western nations have helped Syrian physicians make the most of the situation by providing training on introducing innovations in technology and treatment. Portable ultrasound machines have been introduced and are being used extensively in the management of trauma and shock. This report, prepared by members of the Syrian American Medical Society, documents current needs for health care relief within Syria, focusing on pulmonary, critical care, and sleep medicine, and some of the efforts currently underway to meet those needs.

To report seven cases of broken bioabsorbable femoral crosspins identified by MRI in evaluation of hamstring grafts of the anterior cruciate ligament. Seven cases of broken bioabsorbable crosspins utilized in femoral fixation of ACL hamstring grafts were identified prospectively and retrospectively from our PACs database during a period from 9/1/08 to 8/31/09. All imaging was performed using 1.5 or 3.0 Tesla MRI and were evaluated for T2 signal within and surrounding the crosspin, osteolysis surrounding the fragments, displacement of fragments, and graft integrity. Time from surgery was also recorded. Seven cases of hamstring grafts with broken bioabsorbable crosspins were imaged 4 months to 3 years following grafting. There was osteolysis surrounding the crosspin in all but one case in which the graft was intact but a pin fragment was displaced into the joint. One graft failed due to aseptic foreign-body reaction to the fixation with aggressive osteolysis at 9 months post surgery. In the remaining five, the ACL graft was either completely torn, partially torn, lax, or degenerative and frayed. Of these, the crosspins were broken and angulated with osteolysis surrounding the apex of the angulated fragment or demonstrated lateral extrusion of the peripheral fragment. Bioabsorbable crosspins utilized in femoral fixation of hamstring graft reconstruction of the ACL may become fractured. While the natural history of osteo-integration of these devices as demonstrated by MRI has not been defined, osteolysis surrounding the fragments, extrusion or displacement of the fragments, and graft laxity or failure would suggest that these are abnormal findings that should be reported.

Computed tomography (CT) is used to assess for fracture after knee trauma, but identification of ligamentous injuries may also be beneficial. Our purpose is to assess the potential of dual-energy computed tomography (DECT) for the detection of complete anterior cruciate ligament (ACL) disruption. Sixteen patients with unilateral traumatic ACL disruption (average of 58 days following trauma) confirmed by MRI, and 11 control patients without trauma, underwent DECT of both knees. For each knee, axial, sagittal, and oblique sagittal images (with DECT bone removal, single-energy (SE) bone removal, and DECT tendon-specific color mapping) were reconstructed. Four musculoskeletal radiologists randomly evaluated the 324 DECT reconstructed series (54 knees with 6 displays) separately, to assess for ACL disruption using a five-point scale (1 = definitely not torn, to 5 = definitely torn). ROC analysis was used to compare performance across readers and displays. Sagittal oblique displays (mixed kV soft tissue, SE bone removal, and DECT bone removal) demonstrated higher areas under the curve for ACL disruption (AUC = 0.95, 0.93 and 0.95 respectively) without significant differences in performance between readers (p > 0.23). Inter-reader agreement was also better for these display methods (ICC range 0.62-0.69) compared with other techniques (ICC range 0.41-0.57). Mean sensitivity for ACL disruption was worst for DECT tendon-specific color map and axial images (24 % and 63 % respectively). DECT knee images with oblique sagittal reconstructions using either mixed kV or bone removal displays (either DECT or SE) depict ACL disruption in the subacute or chronic setting with reliable identification by musculoskeletal radiologists.

Comparison of spin echo T1-weighted sequences versus fast spin-echo proton density-weighted sequences for evaluation of meniscal tears at 1.5 T

International Nuclear Information System (INIS)

Wolff, Andrew B.; Pesce, Lorenzo L.; Wu, Jim S.; Smart, L.R.; Medvecky, Michael J.; Haims, Andrew H.

2009-01-01

At our institution, fast spin-echo (FSE) proton density (PD) imaging is used to evaluate articular cartilage, while conventional spin-echo (CSE) T1-weighted sequences have been traditionally used to characterize meniscal pathology. We sought to determine if FSE PD-weighted sequences are equivalent to CSE T1-weighted sequences in the detection of meniscal tears, obviating the need to perform both sequences. We retrospectively reviewed the records of knee arthroscopies performed by two arthroscopy-focused surgeons from an academic medical center over a 2-year period. The preoperative MRI images were interpreted independently by two fellowship-trained musculoskeletal radiologists who graded the sagittal CSE T1 and FSE PD sequences at different sittings with grades 1-5, where 1 = normal meniscus, 2 = probable normal meniscus, 3 indeterminate, 4 = probable torn meniscus, and 5 = torn meniscus. Each meniscus was divided into an anterior and posterior half, and these halves were graded separately. Operative findings provided the gold standard. Receiver operating characteristic (ROC) analysis was performed to compare the two sequences. There were 131 tears in 504 meniscal halves. Using ROC analysis, the reader 1 area under curve for FSE PD was significantly better than CSE T1 (0.939 vs. 0.902, >95% confidence). For reader 2, the difference met good criteria for statistical non-inferiority but not superiority (0.913 for FSE PD and 0.908 for CSE T1; >95% non-inferiority for difference at most of -0.027). FSE PD-weighted sequences, using our institutional protocol, are not inferior to CSE T1-weighted sequences for the detection of meniscal tears and may be superior. (orig.)

Radiological classification of meniscocapsular tears of the anterolateral portion of the lateral meniscus of the knee

International Nuclear Information System (INIS)

George, J.; Packya, N.; Tan, A.H.; Paul, G.

2000-01-01

In an arthroscopic-MRI correlation study of acute injuries to the knee it was found that anterolateral meniscocapsular separations of the lateral aspect of the knee were missed on MRI reporting. Eighty sports-related injuries of the knee were seen by experienced orthopaedic surgeons at the University of Malaya Medical Centre and at the National Sports Centre, Malaysia from January 1996 to July 1997. Fifty of the patients were suspected to have meniscal tears that were either lateral or medial on clinical examination and they were sent for MRI. Many of these patients were tertiary referrals. Magnetic resonance imaging examinations in 27 of the 50 patients were reported as not showing any intrasubstance or obvious meniscocapsular tears, but arthroscopy performed on them revealed anterolateral meniscocapsular tears of the lateral meniscus of varying degrees in nine of these patients. In retrospect the tears could be seen on MRI, and a pattern to the tears was noted and classified as follows. Type 0, normal; type 1, torn inferior or superior meniscocapsular attachment; type 2, both meniscofemoral and meniscotibial ligaments torn but with minimal separation of meniscus and capsule by fluid or synovitis; and type 3, marked separation of meniscus and capsule by fluid (> 3 mm). Ten patients who did not undergo arthroscopy for various personal and financial reasons underwent MRI which showed type 1 and type 2 tears, and were treated conservatively. These patients were all asymptomatic after 4-6 weeks with regard to clinical signs, suggesting a lateral meniscal tear. Magnetic resonance imaging therefore does reveal minor degrees of meniscocapsular tears anterolaterally when one understands the normal anatomy in this region.

Muscle atrophy and fatty degeneration of the rotator cuff muscles have been reported as negative prognostic indicators after rotator cuff repair. Although the Y-shaped view is widely used for measuring the cross-sectional area of the supraspinatus muscle, the contribution of retraction of the torn tendon as well as muscle atrophy must be considered. The purpose of this study was to clarify the relationship between cross-sectional area and tendon retraction or size of the tear. This study included 76 shoulders that were evaluated arthroscopically for the presence and size of tears. Cross-sectional areas of rotator cuff muscles were measured from the Y-shaped view to 3 more medial slices. The occupation ratio and tangent sign were evaluated on the Y-shaped view. The retraction of torn tendon was also measured on the oblique coronal images. On the Y-shaped view, the cross-sectional area of the supraspinatus and the occupation ratio decreased in conjunction with the increase in tear size. A significant decrease in cross-sectional area was noted only in large and massive tears on more medial slices from the Y-shaped view. Significant decreases in the cross-sectional area of the infraspinatus were observed in large and massive tears on all images. A negative correlation was found between tendon retraction and cross-sectional area, which was strongest on the Y-shaped view. To avoid the influence of retraction of the supraspinatus tendon, sufficient medial slices from the musculotendinous junction should be used for evaluation of muscle atrophy.

A persistent atrophy of muscle fibers and an accumulation of fat, collectively referred to as fatty degeneration, commonly occur in patients with chronic rotator cuff tears. The etiology of fatty degeneration and function of the residual rotator cuff musculature have not been well characterized in humans. We hypothesized that muscles from patients with chronic rotator cuff tears have reduced muscle fiber force production, disordered myofibrils, and an accumulation of fat vacuoles. The contractility of muscle fibers from biopsy specimens of supraspinatus muscles of 13 patients with chronic full-thickness posterosuperior rotator cuff tears was measured and compared with data from healthy vastus lateralis muscle fibers. Correlations between muscle fiber contractility, American Shoulder and Elbow Surgeons (ASES) scores, and tear size were analyzed. Histology and electron microscopy were also performed. Torn supraspinatus muscles had a 30% reduction in maximum isometric force production and a 29% reduction in normalized force compared with controls. Normalized supraspinatus fiber force positively correlated with ASES score and negatively correlated with tear size. Disordered sarcomeres were noted, along with an accumulation of lipid-laden macrophages in the extracellular matrix surrounding supraspinatus muscle fibers. Patients with chronic supraspinatus tears have significant reductions in muscle fiber force production. Force production also correlates with ASES scores and tear size. The structural and functional muscle dysfunction of the residual muscle fibers is independent of the additional area taken up by fibrotic tissue. This work may help establish future therapies to restore muscle function after the repair of chronically torn rotator cuff muscles.

Purpose: To determine whether half-Fourier MR image acquisition technique can provide similar information to that of conventional MR acquisition technique for evaluation of meniscal tears. Materials and methods: We studied 101 menisci in 52 patients who were referred for evaluation of meniscal tears. Sagittal MR images of the knee were obtained for all patients by using proton density and T2-weighted SE sequences on a 1-T clinical system. The half-Fourier technique and conventional technique were used for all patients. All other imaging parameters were identical for both sequences (TR/TE=2400/20,70; 3 mm slice thickness; 200x256 matrix; field of view, 200; one signal acquired). Both sets of images were filmed with standard window and level settings. Images were randomised and interpreted independently by two radiologists for the presence of meniscal tears. Images were also subjectively assessed for image quality using a five-point grading scale. Results: On half-Fourier images, Reader 1 interpreted 23 menisci as torn, compared to 28 for Reader 2. On conventional images, Reader 1 interpreted 24 menisci as torn, compared to 26 for Reader 2. Agreement between interpretation of the conventional and that of the half-Fourier images was 99% for Reader 1, and 98% for Reader 2. Agreement between readers for the half-Fourier images was 95%, and for the conventional images 96%. No statistically significant difference was found in the subjective evaluation of image quality between the conventional and half-Fourier images. Conclusion: The half-Fourier acquisition technique compares favourably with the conventional technique for the evaluation of meniscal tears

Idaho enacted legislation protecting real estate agents in situations where they are asked to violate an HIV patient's privacy. Would-be buyers often ask for a psychological impact statement, including whether the home has been a crime site or whether the owners have HIV, about a property in which they are interested. Senate Bill 1313 has guidelines for realtors, who in the past were torn between disclosure and privacy. If buyers request the information in writing, the agent must ask for the owner's consent to release the information. The buyers must be told if the owner declines. The law shields realtors from legal liability once the requirements are met.

A torn meniscus frequently requires surgical fixation or debridement as definitive treatment. Meniscal tears with associated fragment displacement, such as bucket handle and flap tears, can be difficult to recognize and accurately describe on MRI, and displaced fragments can be challenging to identify at surgery. A displaced meniscal fragment can be obscured by synovium or be in a location not usually evaluated at arthroscopy. We present a pictorial essay of meniscal tears with displaced fragments in patients referred to a pediatric hospital in order to increase recognition and accurate interpretation by the radiologist, who in turn can help assist the surgeon in planning appropriate therapy.

Beginning with the issue of the duplicity in the romanticism, we find in Tirso de Molina and Álvares de Azevedo the representation of rivalry present in the donjuanesque theme, the search for the hero identity with the rival and the seduction of the wife of the rival as something valuable. However, the damnation traces the destiny of the romantic hero.

Case report 483: Discoid lateral meniscus (DLM), medially displaced, with complex tear

International Nuclear Information System (INIS)

Howe, M.A.; Buckwalter, K.A.; Braunstein, E.M.; Wojtys, E.M.

1988-01-01

A case of a 9-year-old girl who presented with persistent pain in the left knee was demonstrated to have a discoid lateral meniscus (DLM). The sagittal MR images demonstrated the oval shape of the meniscus, consistent with the typical arthrographic appearance. The coronal images showed that the main substance of the meniscus was displaced medially, with overgrowth of the articular cartilage at the lateral aspect of the joint. The medial aspect of the lateral femoral condyle was concave to accommodate the abnormal meniscus. These findings are consistent with long-standing, medial displacement of the torn meniscus. The literature concerning DLM, an uncommon variant, was reviewed and discussed. (orig.)

The extension from ordinary to stochastic differential equations (SDEs) in pharmacokinetic and pharmacodynamic (PK/PD) modelling is an emerging field and has been motivated in a number of articles [N.R. Kristensen, H. Madsen, S.H. Ingwersen, Using stochastic differential equations for PK/PD model development, J. Pharmacokinet. Pharmacodyn. 32 (February(1)) (2005) 109-141; C.W. Tornøe, R.V.

Res. 22 (August(8)) (2005) 1247-1258; R.V. Overgaard, N. Jonsson, C.W. Tornøe, H. Madsen, Non-linear mixed-effects models with stochastic differential equations: implementation of an estimation algorithm, J. Pharmacokinet. Pharmacodyn. 32 (February(1)) (2005) 85-107; U. Picchini, S. Ditlevsen, A. De Gaetano, Maximum likelihood estimation of a time-inhomogeneous stochastic differential model of glucose dynamics, Math. Med. Biol. 25 (June(2)) (2008) 141-155]. PK/PD models are traditionally based ordinary differential equations (ODEs) with an observation link that incorporates noise. This state-space formulation only allows for observation noise and not for system noise. Extending to SDEs allows for a Wiener noise component in the system equations. This additional noise component enables handling of autocorrelated residuals originating from natural variation or systematic model error. Autocorrelated residuals are often partly ignored in PK/PD modelling although violating the hypothesis for many standard statistical tests. This article presents a package for the statistical program R that is able to handle SDEs in a mixed-effects setting. The estimation method implemented is the FOCE(1) approximation to the population likelihood which is generated from the individual likelihoods that are approximated using the Extended Kalman Filter's one-step predictions.

Diakoptical reliability analysis of transistorized systems

International Nuclear Information System (INIS)

Kontoleon, J.M.; Lynn, J.W.; Green, A.E.

1975-01-01

Limitations both on high-speed core availability and computation time required for assessing the reliability of large-sized and complex electronic systems, such as used for the protection of nuclear reactors, are very serious restrictions which continuously confront the reliability analyst. Diakoptic methods simplify the solution of the electrical-network problem by subdividing a given network into a number of independent subnetworks and then interconnecting the solutions of these smaller parts by a systematic process involving transformations based on connection-matrix elements associated with the interconnecting links. However, the interconnection process is very complicated and it may be used only if the original system has been cut in such a manner that a relation can be established between the constraints appearing at both sides of the cut. Also, in dealing with transistorized systems, one of the difficulties encountered is that of modelling adequately their performance under various operating conditions, since their parameters are strongly affected by the imposed voltage and current levels. In this paper a new interconnection approach is presented which may be of use in the reliability analysis of large-sized transistorized systems. This is based on the partial optimization of the subdivisions of the torn network as well as on the optimization of the torn paths. The solution of the subdivisions is based on the principles of algebraic topology, with an algebraic structure relating the physical variables in a topological structure which defines the interconnection of the discrete elements. Transistors, and other nonlinear devices, are modelled using their actual characteristics, under normal and abnormal operating conditions. Use of so-called k factors is made to facilitate accounting for use of electrical stresses. The approach is demonstrated by way of an example. (author)

CT in the evaluation of pelvic trauma

International Nuclear Information System (INIS)

Federle, M.P.

1986-01-01

Pelvic fractures from motor vehicle accidents are a cause of substantial morbidity and permanent disability, and are the third leading cause of death following blunt trauma. Associated extremity fractures are common, and injury to abdominal and pelvic viscera may occur. Difficulty in establishing the source of hemorrhage may be encountered, especially since pelvic fractures with extraperitoneal bleeding may result in intraperitoneal bleeding through torn fascial planes. The difficulty in properly diagnosing and managing complex fractures of the pelvis and acetabulum is well documented. Prognosis is influenced by the type and extent of pelvic fracture and associated soft tissue injuries. Computed tomography (CT) has proved to be a valuable tool in evaluation of these complex and life-threatening injuries

1993-01-01

On Monday, December 9, 1991, Hurricane Val hit American Samoa. Along with the many homes and buildings that had been destroyed, nine abandoned fishing vessels were torn from their mooring and washed up onto the reef in Pago Pago Harbor. Several hundred gallons of diesel fuel were released into the water; about 12,000 gallons remained onboard the vessels. The efforts of the US Coast Guard (USCG), Federal Emergency Management Agency (FEMA), Samoa Environmental Protection Agency (SEPA), and local contractors helped mitigate the damage. The USCG Pacific Strike Team (PST) was tasked with monitoring, removing, and disposing of the petroleum products that remained onboard the vessels. The strike team also investigated reports of chemical spills throughout the island

Una ridiscussione dei concetti di home e identity nell’Asia globalizzata: il caso di These Foolish Things (2004 e How to Get Filthy Rich in Rising Asia (2013

The aim of the paper is to analyze these topics from a cultural and literary standpoint through the examination of the two different kinds of migrant flows and postcolonial scenarios depicted in These Foolish Things (2004 by the English author Deborah Moggach, and How to Get Filthy Rich in Rising Asia (2013 by the Pakistan novelist Mohsin Hamid. In these novels, the chaotic Indian framework – the former margin of the British empire – is torn between its colonial past and the current effects of the permeability of its borders. It is, therefore, a perfect global context, wherein the experiences and the feelings of the modern Indian identities are reinterpreted by the two authors.

Relation between photoconductivity and g(ε) mobility gap within the range adjoining to the top (mobility end) of valent zone (VZ tail) in a-Si:H film is studied. Stationary photoconductivity within spectral maximum range (χ=0.63μm) at Φ=10 17 photxcm -2 s -1 flow is measured. Density of g(ε) states are controlled using ultrasoft X-ray emission spectroscopy. It is shown, that correlation between photoconductivity and width of VZ tail may reflect the fact of their similar dependence o film heterogeneity: at the increase of share of microholes there occur both expansion of VZ tail and growth of number of respective hydrogen complexes and torn relations which results in drop of photoconductivity

Experiences of some Canadian geologists working in Sudan are described. Glad to be back in Canada after several years of exploration work for various international exploration companies, they have fond memories of the people, who for the most part live under very primitive conditions, and constant exposure to the ravages of tribal wars. They characterize the attitude of Canadians working in Sudan towards the native population as one that puts high values on human rights, safety, work ethics, and individual responsibility. They defend Canadian presence in these far-off regions as beneficial to the native population, by bringing Canadian standards and a civilized version of industry to an area that has seen very little of that in the past.

A multi-state weather generator for daily precipitation for the Torne River basin, northern Sweden/western Finland

2016-03-01

Results showed that the 10-state empirical model represented accumulated 2- to 14-day precipitation most realistically. Further, the distribution of precipitation on wet days in the catchment is related to the placement of a wet day within a wet-spell, and the 10-state models represented this realistically, while the wet/dry models did not. Although all four models accurately reproduced the annual and monthly averages in the training data, all models underestimated inter-annual and inter-seasonal variance. Even so, the 10-state empirical model performed best. We conclude that the multi-state model is a promising candidate for hydrological applications, as it simulates multi-day precipitation well, but that further development is required to improve the simulation of interannual variation.

Providing surgery in a war-torn context: the Médecins Sans Frontières experience in Syria.

Since 2011, civil war has crippled Syria leaving much of the population without access to healthcare. Various field hospitals have been clandestinely set up to provide basic healthcare but few have been able to provide quality surgical care. In 2012, Medecins Sans Frontieres (MSF) began providing surgical care in the Jabal al-Akrad region of north-western Syria. Based on the MSF experience, we describe, for the period 5th September 2012 to 1st January 2014: a) the volume and profile of surgical cases, b) the volume and type of anaesthetic and surgical procedures performed, and c) the intraoperative mortality rate. A descriptive study using routinely collected MSF programme data. Quality surgical care was assured through strict adherence to the following minimum standards: adequate infrastructure, adequate water and sanitation provisions, availability of all essential disposables, drugs and equipment, strict adherence to hygiene requirements and universal precautions, mandatory use of sterile equipment for surgical and anaesthesia procedures, capability for blood transfusion and adequate human resources. During the study period, MSF operated on 578 new patients, of whom 57 % were male and median age was 25 years (Interquartile range: 21-32 years). Violent trauma was the most common surgical indication (n-254, 44 %), followed by obstetric emergencies (n-191, 33 %) and accidental trauma (n-59, 10 %). In total, 712 anaesthetic procedures were performed. General anaesthesia without intubation was the most common type of anaesthesia (47 % of all anaesthetics) followed by spinal anaesthesia (25 %). A total of 831 surgical procedures were performed, just over half being minor/wound care procedures and nearly one fifth, caesarean sections. There were four intra-operative deaths, giving an intra-operative mortality rate of 0.7 %. Surgical needs in a conflict-afflicted setting like Syria are high and include both combat and non-combat indications, particularly obstetric emergencies. Provision of quality surgical care in a complex and volatile setting like this is possible providing appropriate measures, supported by highly experienced staff, can be implemented that allow a specific set of minimum standards of care to be adhered to. This is particularly important when patient outcomes - as a reflection of quality of care - are difficult to assess.

A site (STP) was identified on the skin of the chicken, during defeathering in the slaughter house, at which about 90% of breast skin tears started. This site is on the ventral side of the pectoral tract area. There was no difference in location of this site with respect to different commercial lines, sexes, flocks, or time of the day. In order to demonstrate the importance of a small skin tear to ultimate damage, defeathered chickens with a minor tear at a particular site and undamaged defeathered chickens were passed through the defeathering machine a second time. Thirty-six percent of the STP chickens were torn further, but only a small percentage (about 4%) of the undamaged chickens were harmed.

A large outbreak of tularemia occurred in Kosovo in the early postwar period, 1999-2000. Epidemiologic and environmental investigations were conducted to identify sources of infection, modes of transmission, and household risk factors. Case and control status was verified by enzyme-linked immunosorbent assay, Western blot, and microagglutination assay. A total of 327 serologically confirmed cases of tularemia pharyngitis and cervical lymphadenitis were identified in 21 of 29 Kosovo municipalities. Matched analysis of 46 case households and 76 control households suggested that infection was transmitted through contaminated food or water and that the source of infection was rodents. Environmental circumstances in war-torn Kosovo led to epizootic rodent tularemia and its spread to resettled rural populations living under circumstances of substandard housing, hygiene, and sanitation.

Presented is a historical perspective of one scientist's journey from war-torn Europe to the opportunities presented by a flexible US educational system. It celebrates the opening of the science establishment that began in the 1950s and its fostering of basic research, and recognizes individuals who were instrumental in guiding the author's education as well as those with whom she later participated in collaborative algal plant research. The initial discovery and later elucidation of phycobilisome structure are elaborated, including the structural connection with photosystem II. Furthermore, she summarizes some of her laboratory's results on carotenoids and its exploration of the isoprenoid pathway in cyanobacteria. Finally, she comments on the gender gap and how her generation benefited when opportunities for women scientists were enlarged.

District heating in Flensburg

Energy Technology Data Exchange (ETDEWEB)

Prinz, W.

1981-01-01

The majority of our population, but also of our authorities, are still skeptical or even disapproving towards district heating. The reasons of this negative attitude are partly psychological - e.g. the individualism of the Swiss and their dislike for too centralised structures and ''forced connections'' - but also the existence of finished gas supply networks and the fear of considerable pre-investments and torn streets over years. The following article - held as a speech on the information meeting ''District heating and the possible contribution of nuclear energy'' organised by the Swiss Association for Atomic Energy in Bern shows a practical problem solving at the example of the district heating in Flensburg and deals with these questions.

A more rugged ZnS(Ag) alpha scintillation detector

McElhaney, S.A.; Ramsey, J.A.; Bauer, M.L.; Chiles, M.M.

1990-01-01

Conventional alpha scintillation detectors comprise a phosphor-coated light-pipe covered by a thin aluminized Mylar layer. This opaque radiation entrance window serves as a shield against ambient light entering the detector with minimum alpha attenuation. Unfortunately, Mylar is extremely fragile and easily punctured or torn by sticks, stones, and screws encountered during regular radiation surveys. The authors have been developing an alpha scintillation detector more rugged and durable than conventional models. This paper presents the scintillator assembly, which consists of a mixture of silver-activated zinc sulfide [ZnS(Ag)] and clear epoxy. The ZnS(Ag) scintillation powder is mixed with a low-viscosity, optically transparent epoxy and poured into a glass-smooth mold of desired shape and size

Resistance to permeation of noxious chemical substances should be accompanied by resistance to mechanical factors because the glove material may be torn, cut or punctured in the workplace. This study reports on glove materials, protecting against mineral oils and mechanical hazards, made of carboxylated acrylonitrile-butadiene rubber (XNBR) latex. The obtained materials were characterized by a very high resistance of the produced materials to oil permeation (breakthrough time > 480 min). The mechanical properties, and especially tear resistance, of the studied materials were improved after the addition of modified bentonite (nanofiller) to the XNBR latex mixture. The nanocomposite meets the requirements in terms of parameters characterizing tear, abrasion, cut and puncture resistance. Therefore, the developed material may be used for the production of multifunctional protective gloves.

On the behavior of crack surface ligaments

International Nuclear Information System (INIS)

Nilsson, P.; Staahle, P.; Sundin, K.G.

1998-01-01

Small ligaments connecting the fracture surfaces just behind a moving crack front are assumed to exist under certain conditions. The ligaments are rapidly torn as the crack advances. Inelastic straining of such ligaments influences the energy balance in the fracture process. The rapid tearing of a single ligament is studied both numerically and experimentally. An elastic visco-plastic material model is adopted for finite-element calculations. The results show that relatively large amounts of energy are dissipated during the tearing process. Further, the energy needed to tear a ligament increases rapidly with increasing tearing rate. The computed behavior is partly verified in a few preliminary experiments. The implications for slow stable crack tip speeds during dynamic fracture are discussed. (orig.)

LE PÈRE INVISIBLE ET SILENCIEUX CHEZ GISÈLE FOURNIER (The Invisible and Silent Father by Gisèle Fournier

2015-06-01

Full Text Available The game of visible and invisible led by the paternal character in the novel Non-dits (2000 of Gisèle Fournier betrays the threat which presses on the story of a family torn by the secrets of the past. The father keeps out of the oppressive closed world he is sentenced to, using silence. Far from losing him, this attitude allows him to be marked out. And actually in the slow succession of the novel’s monologues, his image and his presence persist even after his suicide. The look of both character and reader is thus headed towards this paternal figure. Once narrativized, this vision allows us to question the contemporary illness which affects the transmission.

KIPS GDS teardown

International Nuclear Information System (INIS)

1979-01-01

Phase I of the Kilowatt Isotope Power System Program required a 1000 endurance test on the Ground Demonstration System (GDS). This report covers the teardown and inspection of the GDS after completion of over 1000 accumulated hr. After 1124.1 hours of operation, the GDS was torn down and inspected. The longest continuous run was 573.9 hr. With one exception, all shutdowns were intentional. The unintentional shutdown was not related to system operation, terminating a 447.8 hr run. The unit was restarted and the 573.9 hr run was completed. The minimum time component in the GDS, the NaK filled thermal sensor, accumulated 1043.1 operating hr. In general, the hardware was in excellent condition. Cases where discrepancies were noted are listed

Abstract Objective. When planning surgery in patients with rotator cuff tear, strength of bone at the tendon insertion and trabecular bone structure in the greater tuberosity are usually taken into consideration. We investigated radiographic changes in bone structure of the greater tuberosity in rotator cuff tears.Design. Twenty-two human cadaveric shoulders from subjects ranging from 55 to 75 years of age were obtained. The integrity of the rotator cuff was examined by sonography to determine if it is intact without any tear, or torn partially or completely. The humeral head was sectioned in 3 mm thick coronal slab sections and microradiographed. After digitization of the microradiographs and imaging processing with in-house semi-automated image processing software tools developed using software interfaces on a Sun workstation, the trabecular histomorphometrical structural parameters and connectivity in the greater tuberosity were quantified. The degenerative changes on the surface of the greater tuberosity were interpreted blindly by 2 independent readers.Results. Among the 22 shoulder specimens, the rotator cuff was found intact in 10 shoulders, partially in 7 and fully torn in 5. Statistically significant loss in apparent trabecular bone volume fraction, number of trabecular nodes, and number of trabecular branches, and a statistically significant increase in apparent trabecular separation and number of trabecular free ends were found in the greater tuberosity of the shoulders with tears. The loss was greater in association with full tear than in partial tear. Thickening of the cortical margin of the enthesis, irregularity of its surface, and calcification beyond the tidemark were observed in 2 (20%) shoulders with intact rotator cuff, in 6 (86%) shoulders with partial tear, and in 5 (100%) shoulders with full tear.Conclusions. Rotator cuff tears are associated with degenerative changes on the bone surface and with disuse osteopenia of the greater tuberosity

Whistleblowing--is it really worth the consequences?

Delk, Kayla L

2013-02-01

This article explores general principles of state whistleblower laws and alerts nurses to considerations when deciding whether to report an employer violation. Reporting an employer violation can be difficult for any employee but especially for nurses because nurses are torn between their desire and duty to advocate for clients' safety and their desire to maintain employment. The author suggests questions to consider when deciding to "blow the whistle" and alerts nurses to statutes of limitations that may affect when nurses must report violations. The article also illuminates policy and procedural issues for various states that affect how and to whom nurses report violations to protect themselves under whistleblower protection laws. Finally, this article explores personal and professional consequences that nurses should consider before reporting violations. Copyright 2013, SLACK Incorporated.

Full Text Available En décadas pasadas, la inmigración se tornó un "problema social" para el gobierno español, lo que le requirió generar mecanismos para detectar, clasificar y organizar dicho fenómeno. Hoy se capacitan profesionales cuyo conocimiento experto los convierte en referencia. El objetivo aquí es analizar cómo los saberes expertos intervienen en la identificación de la "inmigración" en algunos sectores de la sociedad española. Se reflexiona sobre cómo conceptos de cultura se mezclan con el "sentido común", construyendo un marco significativo hegemónico que marca los límites del debate social sobre "inmigración" y recrea parámetros de distinción entre los diferentes grupos sociales.

A woman in her 70s with Churg-Strauss syndrome presented with epigastric pain. She was being treated with steroids at the time of admission. Computed tomography showed swelling of the gallbladder, and percutaneous transhepatic cholangiography revealed bloody secretion. On duodenoscopy, bleeding was observed from the orifice of the major duodenal papilla. Emergency cholecystectomy was performed under a diagnosis of hemorrhagic cholecystitis;intraoperatively, extensive hematoma was detected in the thickened wall of the gallbladder. Subsequent histopathological examination revealed mucosal ulceration with infiltration of inflammatory cells, torn small vessels, and extensive transmural bleeding and abscess formation in the thickened wall of the gallbladder. We considered that the hemorrhagic cholecystitis was induced by either vasculitis or corticosteroid therapy. To the best of our knowledge, this is the first report of hemorrhagic cholecystitis associated with Churg-Strauss syndrome.

Floating knee injuries are frequently associated with other concomitant injuries to the ipsilateral limb or other parts of body of which injury to the ipsilateral knee ligaments carries significance for various reasons. A middle-aged man sustained a floating knee injury following RTA. DCS fixation by bridge plating technique for the distal femur and lateral buttress plating by MIPO technique for proximal tibia were planned and executed under spinal anesthesia with image intensifier. In addition, there were patellar tendon rupture along with avulsion of VMO from the medial border of patella and torn MPFL, which we have missed initially. To the best of our knowledge no similar case has been reported in English literature so far. We have reviewed the literature and proposed a different interpretation of Blake and McBride classification.

2016-08-01

Single-particle imaging (SPI) with X-ray free-electron lasers has the potential to change fundamentally how biomacromolecules are imaged. The structure would be derived from millions of diffraction patterns, each from a different copy of the macromolecule before it is torn apart by radiation damage. The challenges posed by the resultant data stream are staggering: millions of incomplete, noisy and un-oriented patterns have to be computationally assembled into a three-dimensional intensity map and then phase reconstructed. In this paper, the Dragonfly software package is described, based on a parallel implementation of the expand-maximize-compress reconstruction algorithm that is well suited for this task. Auxiliary modules to simulate SPI data streams are also included to assess the feasibility of proposed SPI experiments at the Linac Coherent Light Source, Stanford, California, USA.

Full Text Available We report the case of a 36-year-old lorry driver who sustained left dorsal radiocarpal fracture dislocation and left median nerve injury in a traffic accident in 2010. Emergency operation of closed reduction, cross-wrist-bridging external fixation, percutaneous transradial styloid Kirschner wire fixation, decompression of left median nerve, and repair of the partially torn palmar radiocarpal ligament were performed under general anaesthesia. Because of the persistent depressed dorsal articular rim fracture of left distal radius, another operation of open reduction, corticocancellous bone grafting, and dorsal buttress plating was performed 5 days after the initial operation. Six months after the operation, the patient enjoyed good range of wrist motion but weak twisting power, especially in supination. There was no radiological feature of radiocarpal subluxation.

We describe an innovative strategy implemented to support national staff at Istarlin Hospital in the conflict setting of Somalia; and report on inpatient morbidities, mortality and adverse hospital exit outcomes. This was a retrospective analysis of hospital data for 2011. Of 8584 admitted patients, the largest numbers were for lower respiratory tract infections (LRTI) (2114; 25%), normal deliveries (1355; 16%) and diarrhoeal diseases (715; 8%). The highest contributors to mortality were gunshot wounds in surgery (18/30; 60%), LRTIs in internal medicine (6/32; 19%) and malnutrition in paediatrics (30/81; 37%). Adverse hospital exit outcomes (deaths and absconded) were well within thresholds set by Médecins Sans Frontières. With a support package, satisfactory standards of care were met for hospital care in Somalia.

Accurate and practical malaria diagnostics, such as immunochromatographic rapid diagnostic tests (RDTs), have the potential to avert unnecessary treatments and save lives. Volunteer community health workers (CHWs) represent a potentially valuable human resource for expanding this technology to where it is most needed, remote rural communities in sub-Saharan Africa with limited health facilities and personnel. This study reports on a training programme for CHWs to incorporate RDTs into their management strategy for febrile children in the Democratic Republic of Congo, a tropical African setting ravaged by human conflict. Prospective cohort study, satisfaction questionnaire and decision analysis. Twelve CHWs were trained to safely and accurately perform and interpret RDTs, then successfully implemented rapid diagnostic testing in their remote community in a cohort of 357 febrile children. CHWs were uniformly positive in evaluating RDTs for their utility and ease of use. However, high malaria prevalence in this cohort (93% by RDTs, 88% by light microscopy) limited the cost-effectiveness of RDTs compared to presumptive treatment of all febrile children, as evidenced by findings from a simplified decision analysis. CHWs can safely and effectively use RDTs in their management of febrile children; however, cost-effectiveness of RDTs is limited in zones of high malaria prevalence.

Veronese, Guido; Pepe, Alessandro

2017-07-01

The aim of this work was to discriminate between healthy children and children at risk of developing mental impairments by evaluating the impact on contextual and individual factors of a context characterized by war. We tested the hypothesis that a linear discriminant function composed of trauma, life satisfaction, and affect balance has the power to classify the children as community or clinical referred. Membership of the clinical-referred group was associated with poorer life satisfaction and higher levels of trauma. Community-referred profiles were associated with lesser trauma. Perceived life satisfaction regarding family and school was the main contributor to the discriminant function.

Psychiatric social work assessment showed that she had a frictional and conflicting relationship with her husband. Due to which her quality of life was compromised. On further assessment it was found that the client was having moderate level of functioning. Impact of Event Scale score suggested cutoff for a probable diagnosis of posttraumatic stress disorder (PTSD, consider consulting a mental health professional. The client was referred to a psychiatrist for further assessment and treatment, and she was diagnosed as PTSD. Later individual, marital, and group interventions were provided and moderate improvement in terms of self-esteem, reducing anxiety, and enhancing coping mechanism. The present case study prompts us to look at the intersection of mental health, disaster, and gender. Disasters have been taking place since time immemorial and will continue to occur. A significant percentage of survivors develop profound, debilitating posttraumatic stress reactions requiring extended mental health intervention. These extreme stress reactions include fear and irrational behaviour, shock, immobilisation, withdrawal, denial and intrusive thoughts, hyper-vigilance, easy startle, insomnia, decreased attention and concentration, and psycho-physiological reactions. The social work professionals have long been involved with disaster relief work, both at individual and community level.

Pen Rearing and Imprinting of Fall Chinook Salmon, 1986 Annual Report.

Pen rearing studies during 1986 completed the second of three years intended for rearing and releasing upriver bright fall chinook salmon (Oncorhynchus tshawytscha) from two study sites, a backwater and a pond, adjacent to the Columbia River; both areas are located in the Jonn Day Reservoir. Results of this study in 1984 and 1985 showed that fish could be successfully reared in net pens and that growth and physiological development of the off-station reared fish proceeded at a faster rate than in fish reared at a hatchery. Transfer of fish from the hatchery to off-station sites at Social Security Pond (pond) and Rock Creek (backwater) during early March increased the period of rearing in 1986 by about four weeks. The increased period of rearing allowed all treatments of fed fish to reach a minimum weight of YU fish/lb by release. Differences in growth of fed fish between regular density treatments and additional, high density treatments (double and triple the regular densities) were not significantly different (P > 0.05), but growth of all fed fish reared off-station was again significantly better than that of hatchery reared fish (P < 0.05), Mortalities in all groups of fed fish were low. Physiological development of fed fish was similar in all treatments. At release, development of fish at Social Security Pond appeared to be somewhat ahead of fish at Rock Creek on the same dates however, none of the groups of fed fish achieved a high state of smoltification by release. Unfed fish grew poorly over the redring period, and at release were significantly smaller than either fed groups at the off-station sites, or the control groups reared at the hatchery (P < 0.05). Development of unfed fish toward smoltification was much slower than of fed fish. Mortality of all groups of unfed fish, including the barrier net, was relatively low. Health of all fish reared off-station remained good over the rearing period, and no outbreaks of disease were noted. On-site marking and

The thread of depression throughout the life and works of Leo Tolstoy.

Tolstoy, the author of two masterpieces, War and Peace and Anna Karenina, remains a writer of genius. Yet, after writing War and Peace, his existence had been torn apart by a serious depression. This depression, which was melancholic in character, almost destroyed him and, once he had finished Anna Karenina, led him to want to renounce not only sexuality but also literary creation and material possessions. Through examining Tolstoy's life and work, the author tries to uncover the underground paths of this depression, which emerged brutally in the middle of his life, and to understand why his creative genius dried up. Like Leonardo da Vinci, Tolstoy turned away from his artistic work, declaring that 'art is not only useless but even harmful', and thereafter devoted himself to philosophical, political and religious writings. These new sublimations would help him to recover his health.

Full Text Available The biographical and historical-literary analysis of works of the modern writer Jan Rybowicz indicates that having a family of one’s own was an unreachable dream for the artist, which affected his self-esteem and was a chance for his complete fulfillment. Letters to Elisabeth are showing problems of a sensitive artist in his contacts with women. The selected literary works draw attention at the issues of a lonely man missing a wife and children which he has never had. Autobiographical prose points to the passing time and difficult reality that made having a family impossible for the writer. Jan Rybowicz’s works show a man torn between his wishes and reality. A desire of having his own family gave him the strength to write, but, on the other hand, it made him suffer.

Critical Places Beyond the Psychology of Well-Being and Competitiveness.

2018-05-14

The purpose of the present contribution is to look beyond the limits evident in dualistic discourses in educational practices. Torn between the promises of well-being or the hard facts of competitiveness, educational institutions at all levels of instruction might miss the point of a more holistic approach to learning and creativity. Looking beyond dichotomous discourses in educational practices is harder than ever, in a world where globalisation demands high standards of competitiveness and neoliberalism denies all but economic growth targets. Approaches that envision different solutions are necessarily imaginative, critical and alternative to rigid discourses. In order to find foundational evidence for alternative ways of thinking and talking about learning, I will look at how Dewian and Vygotskyan conceptualisations walk the same paths and go towards holistic suggestions. Concluding remarks will address the disruptive potential of critical thinking in schools for the future.

Trauma and Second Language Learning among Laotian Refugees

2011-01-01

Full Text Available Unprecedented numbers of adult refugee learners are entering ESL classes, many of whom escaped war-torn countries and endured long stays in refugee camps. Research in public health and psychology has documented high levels of depression, anxiety, and posttraumatic stress disorder in refugee populations. Drawing on ethnographic research with Laotian refugee women who experienced pre-settlement trauma during the Vietnam War and interviews with bilingual mental health professionals, this article examines current second language acquisition theories to consider how they elucidate the effect of trauma on second language learning. The article offers cross-cultural perspectives about the impact of trauma and recommendations for working with adult refugee learners who have experienced trauma. Research findings have implications for ESL instructors and second language researchers concerned with the impact of pre-resettlement experiences on second language acquisition and implications for classroom instruction.

By bond-anchorage property tests at 20°C ∼500°C, the distribution of shear stress between carbon fiber sheets and concrete at all levels of loading and anchorage lengths were measured, which means the bond lengths during CFRP sheets are pulled off at the same time when the concrete is torn and stripped were gotten. The failure modes were obtained. In addition, the failure loads were measured, and the calculated formulas of anchorage lengths were identified by fitting at high temperature. It can be seen that the anchorage lengths of carbon fiber sheets increase with increasing temperature at 20°C ∼100°C, the anchorage lengths of carbon fiber sheets decrease with increasing temperature at 100°C ∼500°C. Tests prove that AASCM has favorable high-temperature resistant and bond anchorage properties.

Blogging 9/11 and Memory Discourse

This article highlights a few of the salient discursive and linguistic patterns that recur in the 9/11 narratives that have multiplied online on several dedicated websites and investigates the evolution of 9/11 cultural memory practices, torn between the discourse of the unrepresentable and the imperative to remember. It claims that blogging 9/11, immediately after the attacks and over the years, well illustrates how the logic of memory and its interpretation of the past follow different criteria from history writing. It shows how memorialization practices, dictated by the fear of forgetting the vanishing present, contribute to that excess of memory that lies at the core of the instability and mutual competition of sources retrieved on the Internet and that might ultimately lead to a rethinking of what is the contribution of collective memory to historiography.

Dynamic forces on agglomerated particles caused by high-intensity ultrasound.

Knoop, Claas; Fritsching, Udo

2014-03-01

In this paper the acoustic forces on particles and agglomerates caused by high-intensity ultrasound in gaseous atmosphere are derived by means of computational fluid dynamics (CFD). Sound induced forces cause an oscillating stress scenario where the primary particles of an agglomerate are alternatingly pressed together and torn apart with the frequency of the applied wave. A comparison of the calculated acoustic forces with respect to the inter particle adhesion forces from Van-der-Waals and liquid bridge interactions reveals that the separation forces may reach the same order of magnitude for 80 μm sized SiO2-particles. Hence, with finite probability acoustically agitated gases may de-agglomerate/disperse solid agglomerate structures. This effect is confirmed by dispersion experiments in an acoustic particle levitation setup. Copyright © 2013 Elsevier B.V. All rights reserved.

Wang, J.; Magee, D.; Schneider, J. A.

2009-01-01

The dynamic mechanical properties and fracture surface morphologies were evaluated for a commercial epoxy resin toughened with two types of core-shell rubber (CSR) toughening agents (Kane Ace(Registered TradeMark) MX130 and MX960). The impact resistance (R) was evaluated by the resulting breaking energy measured in Charpy impact tests conducted on an instrumented drop tower. The resulting fracture surface morphologies were examined using Scanning Electron Microscopy (SEM). Fractographic observations of the CSR toughened epoxy tested at ambient temperature, showed a fracture as characterized by slender dendrite textures with large voids. The increasing number of dendrites and decreasing size of scale-like texture with more CSR particles corresponded with increased R. As the temperature decreased to Liquid Nitrogen (LN 2), the fracture surfaces showed a fracture characterized by a rough, torn texture containing many river markings and deep furrows.

Thirty-eight knees with clinically suspected meniscal tears were examined with high resolution computed tomography(HRCT) immediately following double contrast arthrography. All subsequently underwent arthroscopy. The findings of postarthrogram HRCT and arthroscopy were compared to evaluated the usefulness of postarthrogram HRCT in diagnosis of the meniscal tears. The sensitivity, specificity and accuracy of HRCT were 96.2%. 83.3% and 92.1% respectively. The anatomic details of the meniscal tears were clearly visible on the HRCT scans. Sagittal and coronal reformation views well visualized the horizontal tears and the relationship of torn meniscal fragments, and well differential the peripheral tears from the synovial recess. Our result indicate that postarthrogram HRCT not only is a sensitive and effective method for the detection and characterization of the meniscal tears, but also provides arthroscopists with the appropriate surgical plans

Questioning the role of Facebook in maintaining Syrian social capital during the Syrian crisis.

The Syrian crisis is considered the 'world's single largest crisis for almost a quarter of a century that has the biggest refugee population from a single conflict in a generation' (UN High Commissioner for Refugees, 2016). The rapid adoption of Facebook among Syrians questions whether it helps in maintaining the social capital of a war-torn nation and a dispersed Syrian population worldwide. Data was collected by means of a Facebook survey from 964 Syrian users. Results indicated that Facebook enhanced social identity and social capital through facilitating communication, collaboration and resource sharing among dispersed Syrians inside and outside the country. However, the offline rift of the nation was extended to Facebook through promoting hate speech among opposed parties. Results of this study may advance the understanding of the role of Facebook on social capital in countries going through similar crisis situations.

We present a case of intraarticular myositis ossificans in the right knee of a child. Myositis ossificans (MO), though relatively rare in childhood and even more uncommon within a joint, should be included in the differential diagnosis of an intra-articular mass when indicated by the typical clinical, radiographic, and histologic findings. An 11-year-old male presented with a history of trauma to his right knee. Four weeks after the initial injury, an MRI demonstrated evidence of an ACL rupture with a ''cystic mass'' within the intercondylar notch along the anterior surface of the torn ligament. At subsequent arthroscopy, the mass noted on MRI was removed. The histology was consistent with MO. The authors believe this to be the first case of MO in the intercondylar notch detected by MRI, treated by arthroscopy, and confirmed by histology. (orig.)

2017-12-01

The acromioclavicular joint represents the link between the clavicle and the scapula, which is responsible for the synchronized dynamic of the shoulder girdle. Chronic acromioclavicular joint instability involves changes in the orientation of the scapula, which provokes cinematic alterations that might result in chronic pain. Several surgical strategies for the management of patients with chronic and symptomatic acromioclavicular joint instability have been described. The range of possibilities includes anatomical and non-anatomical techniques, open and arthroscopy-assisted procedures, and biological and synthetic grafts. Surgical management of chronic acromioclavicular joint instability should involve the reconstruction of the torn ligaments because it is accepted that from three weeks after the injury, these structures may lack healing potential. Here, we provide a review of the literature regarding the management of chronic acromioclavicular joint instability. Expert opinion, Level V.

This paper reports that the outlook for exploration depends on the economic health of the mining industry and, in turn, general economic conditions. It is too early to determine the overall impact of the cessation of hostilities in the Persian Gulf War. Its conclusion would allow funds to be redirected to individual country's economies. The rebuilding of the war-damaged countries will probably translate into net increases in demand for the minerals industry. A return to stability in energy costs will also benefit the mining industry. Alternatively, the capital requirements to rebuild war-torn countries could put some strain on capital markets and affect the funds available for private commercial investment. Along with increasing the cost of capital to mining operations, a capital shortage could stall recovery of western industrialized economies that are currently in recession

The recently completed project to repair the ChNPP Unit 3/4 ventilation stack is the first international project providing a direct physical improvement and safety upgrade at the Shelter (Ukrytie) facility. The 1986 explosion at Chernobyl NPP Unit 4 severely damaged the ventilation stack framework of bracing and its foundation. At one node, where six elements of the framework joined together, one element was completely missing one element was torn from the node and left hanging from its other end, and one element was badly bent and dented. Foundation supports were knocked measurably off plumb. Repair of the ChNPP ventilation stack is the first international project providing direct physical improvement and safety upgrade at the Shelter facility. The repairs have restored the stack to full design strength, from an emergency condition with a high probability of collapse

Full Text Available One of the success factor to achieve education goals is the good communication between the student’s parents and the school. Most of Indonesian schools use written communication in form of communicator book, renewed yearly when the student move to the new grade. All of the important information contained in the conversation will be lost if the book is missing, torn, damaged or replaced by the new book. The response time of the conversation is very slow, parent should wait the answer from the school until the student goes home. A mobile application is designed to replace the communicator book electronically. The application is hybrid, enables the parent to communicate easily to the class teacher, counselors, health services and also the school managements. The design has been reviewed dan feedback given from the users.

It relates the history of creation of Gorky’s essay “A.A.Blok” (1923 to the author’s reflections about deformation of the old and the birth of the new humanism in post-revolutionary era. Gorky was one of the few Blok’s contemporaries who understood the poet’s concern about the collapse of the old humanism in the world torn by wars and revolutions. It was Gorky who listen- ing to Blok’s presentation “Heine in Russia” was so affected by it that proposed to devote a special seminar related to this theme in the department of the publishing house “World Literature.” This seminar prompted Blok to write his famous article, “The Collapse of Humanism” (1919.

Full Text Available Since their arrival in New Granada, the dominicans promoted the so called “Third Order”, which brought a number of lay organizations such as fraternities, sororities and devouts groups. This article analyzes such organizations as key nodes of colonial society, through a symbiotic relationship with the colonial elite, which continued until the dawn of republican era. This link were favored by institutions such as chaplaincies and pious deeds. It allowed, among other things, the provision of many of the new members of the order and endowed convents of movable and immovable property and capital necessary for its functioning, in exchange for ensuring social order and provide prestige for this life and salvation for the other. This successful model was torn apart with the advent of the Enlightenment and will fall precipitously shortly after Independence.

Magical Realism in the Holocaust Literature of the Postwar Generations

Ortner, Jessica

2014-01-01

This article investigates the use of magical realism in two Holocaust novels written by the contemporary Austrian writers Doron Rabinovici and Robert Schindel, who both are descendants of Holocaust survivors. I will argue that Rabinovici and Schindel not only use the narrative technique of magic...... Schindel’s novel Born-Where (Gebürtig, 1994) visualize the situation of being torn between two contradictory perceptions of the world: on the one hand, the “normal” perception of the world, based on the present norms of society, and on the other hand, a perception of the traumatic world bestowed by family...... history, which clearly subverts those present norms. Whereas the magical element in The Search for M. is inherent in the contradictions of the story line, it is shown in a bewildering narrative structure in Born-Where (Genette, 1980)....

Parallel Object Oriented MD Simulation Program for Long Time Simulations of Metallic Glasses and Undercooled Liquids

Science.gov (United States)

Böddeker, B.; Teichler, H.

The MD simulation program TABB is motivated by the need of long time simulations for the investigation of slow processes near the glass transition of glass forming alloys. TABB is written in C++ with a high degree of flexibility: TABB allows the use of any short ranged pair potentials or EAM potentials, by generating and using a spline representation of all functions and their derivatives. TABB supports several numerical integration algorithms like the Runge-Kotta or the modified Gear-predictor-corrector algorithm of order five. The boundary conditions can be chosen to resemble the geometry of bulk materials or films. The simulation box length or the pressure can be fixed for each dimension separately. TABB may be used in isokinetic, isoenergeric or canonic (with random forces) mode. TABB contains a simple instruction interpreter to easily control the parameters and options during the simulation. The same source code can be compiled either for workstations or for parallel computers. The main optimization goal of TABB is to allow long time simulations of medium or small sized systems. To make this possible, much attention is spent on the optimized communication between the nodes. TABB uses a domain decomposition procedure. To use many nodes with a small system, the domain size has to be small compared to the range of particle interactions. In the limit of many nodes for only few atoms, the bottle neck of communication is the latency time. TABB minimizes the number of pairs of domains containing atoms that interact between these domains. This procedure minimizes the need of communication calls between pairs of nodes. TABB decides automatically, to how many, and to which directions the decomposition shall be applied. E.g., in the case of one dimensional domain decomposition, the simulation box is only split into "slabs" along a selected direction. The three dimensional domain decomposition is best with respect to the number of interacting domains only for simulations

Torn between dual roles: the experiences of nurse-family members when a loved one is hospitalised in a critical condition.

To understand and interpret the experiences of nurse-family members when a family member or loved one is hospitalised in a critical condition. Having a family member hospitalised with a critical illness is a traumatic stressor, often with long-term sequelae. Providing holistic care for family members who are also nurses makes the provision of care more complex because of their professional expertise; yet few studies have explored this issue. In this descriptive study, qualitative data were collected using a questionnaire and analysed using van Manen's (Researching Lived Experience: Human Science for an Action Sensitive Pedagogy, 1990, State University of New York Press, London, ON) six-step approach. Twenty nurse-family members completed an online questionnaire in June 2013. Qualitative findings from 19 participants were included in the analysis. The phenomenological analysis approach described by van Manen (Researching Lived Experience: Human Science for an Action Sensitive Pedagogy, 1990, State University of New York Press, London, ON) was used to describe and interpret nurse-family member experiences. Nurse-family members experience significant dual role conflicts between their personal and professional personas due to their specialised knowledge, need for watchfulness and competing expectations. Our findings describe how dual role conflicts developed and were managed, and reveal the resultant emotional toll and psychological distress as nurse-family members struggled to resolve these conflicts. Nurse-family members require a different type of care than general public family members, yet their unique needs are often unmet, leading to increased anxiety and distress that could potentially be minimised. An increased awareness and emphasis on the nurse-family member experience can ensure health care professionals are better placed to provide appropriate and targeted care to minimise distressing dual role conflicts. There is a need for targeted and specialised communication appropriate to each nurse-family members' needs and level of understanding, and to clarify expectations to ensure nurse-family members' professional knowledge and skills are recognised and respected without being exploited. © 2015 John Wiley & Sons Ltd.

Joint surgery is often complicated by gradual bone and cartilage deterioration that eventually leads to secondary osteoarthritis. The primary objective of this study was to identify preoperative risk factors for gleno-humeral osteoarthritis after rotator cuff repair. The secondary objectives were to assess whether the risk of gleno-humeral osteoarthritis was influenced by the operative technique, occurrence of postoperative complications, cuff healing, and muscle degeneration and to determine whether gleno-humeral osteoarthritis affected the clinical outcome. The development of gleno-humeral osteoarthritis affects the postoperative clinical outcome. A retrospective multicentre study of patients who underwent rotator cuff repair in 2003 and were re-evaluated at least 10 years later was conducted under the aegis of the Société française de chirurgie orthopédique et traumatique (SOFCOT). Osteoarthritis severity was graded according to the Samilson-Prieto classification. Four hundred and one patients were included. At last follow-up, at least 10 years after surgery, the radiological Samilson-Prieto grades were distributed as follows: 0, n=181 (45%); 1, n=142 (n=35%); 2, n=57 (14%); 3, n=14 (4%); and 4, n=7 (2%). The mean Constant score was significantly higher in the patients without than with osteoarthritis at last follow-up (79/100 vs. 73/100, Posteoarthritis was significantly higher in the group with unhealed or re-torn cuffs (Sugaya type 4 or 5) than in the group with healed cuffs (Sugaya type 1, 2, or 3) (46% vs. 25%, P=0.012). Our study showed no associations linking the risk of gleno-humeral osteoarthritis to the patient activity profile, history of shoulder injury, or preoperative symptom duration. In contrast, statistically significant associations were identified between gleno-humeral osteoarthritis and age, male gender, initial tear severity, and the pain and mobility components of the preoperative Constant score.

The arthroscopic suture-bridge technique has proved to provide biomechanically firm fixation of the torn rotator cuff to the tuberosity by increasing the footprint contact area and pressure. However, a marginal dog-ear deformity is encountered not infrequently when this technique is used, impeding full restoration of the torn cuff. To evaluate the structural and functional outcomes of the use of a modified suture-bridge technique to prevent a marginal dog-ear deformity compared with a conventional suture-bridge method in rotator cuff repair. Cohort study; Level of evidence 2. A consecutive series of 71 patients aged 50 to 65 years who underwent arthroscopic rotator cuff repair for full-thickness medium-sized to massive tears was evaluated. Patients were divided into 2 groups according to repair technique: a conventional suture-bridge technique (34 patients; group A) versus a modified suture-bridge technique to prevent a marginal dog-ear deformity (37 patients; group B). Radiographic evaluations included postoperative cuff integrity using MRI. Functional evaluations included pre- and postoperative range of motion (ROM), pain visual analog scale (VAS), the University of California, Los Angeles (UCLA) shoulder rating scale, the Constant score, and the American Shoulder and Elbow Surgeons (ASES) score. All patients were followed up clinically at a minimum of 1 year. When the 2 surgical techniques were compared, postoperative structural integrity by Sugaya classification showed the distribution of types I:II:III:IV:V to be 4:20:2:4:4 in group A and 20:12:4:0:1 in group B. More subjects in group B had a favorable Sugaya type compared with group A (P bridge technique repairs were found in the retear group (P = .03). There were significant differences between healed and retear groups in functional outcome scores, with worse results in the retear group. A modified suture-bridge technique to prevent a marginal dog-ear deformity provided better structural outcomes than a

Background: In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the 'bridging sign', which has not been previously described. Purpose: To describe the 'bridging sign' on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear. Material and Methods: Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled. The medical records of the 29 patients were retrospectively reviewed for the duration of shoulder pain, rotator cuff tears, and associated arthroscopic findings: biceps tendon abnormality and superior glenoid labral tear. Then, preoperative shoulder MR images were retrospectively reviewed for the presence or absence of the 'bridging sign' and associated MR findings: periarticular fluid and fatty atrophy of the supraspinatus and subscapularis muscles. The type of rotator cuff tear associated with the 'bridging sign' was assessed and the sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of a certain type of rotator cuff tear were calculated. Associated arthroscopic and MR findings and mean duration of the shoulder pain between the patients with and without the 'bridging sign' were compared. Results: The 'bridging sign' was seen in 17 of 29 patients and corresponded to a complex of the torn and superomedially retracted subscapularis tendon, coracohumeral ligament, and superior glenohumeral ligament, adhered to the anterior margin of the torn supraspinatus (SSP) tendon on arthroscopy. All patients with the 'bridging sign' had combined full-thickness tear (FTT) of the cranial 1/2 portion of the subscapularis tendon and anterior 1/2 portion of the SSP tendon. The sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of combined FTTs of the SSC tendon and anterior portion of the SSP tendon were 81.0%, 100%, and 86

2007-01-01

The objective was to describe the imaging appearances and location of delamination tears of the rotator cuff tendons on non-contrast conventional MR imaging. This study was reviewed and approved by our Institutional Review Board. The reports of 548 consecutive MR examinations of the shoulder were reviewed, looking for mention or description of delamination tears of the rotator cuff. The images of the identified cases were then reviewed by two radiologists to confirm the findings. Correlation with surgical and arthroscopic information was then performed. Delamination tears were defined as horizontal retraction of either the bursal or articular surface of the tendon, manifest as thickening of the torn retracted edge, and/or interstitial splitting of the tendon, manifest as fluid-like high signal intensity on fat-suppressed T2-weighted oblique coronal images. Fourteen cases of delamination tears were identified in 13 patients. Ten of the cases involved the supraspinatus tendon, all with articular surface involvement. Nine of these supraspinatus cases were isolated tears and one occurred as part of a full thickness tear. All 10 of these supraspinatus cases showed medial retraction of the articular surface of the tendon, with thickening of the retracted edge, and 5 of the 10 had a demonstrable horizontal cleft in the interstitium. Four cases involved the subscapularis tendon, with articular surface disruption in three and pure interstitial delamination in one. Medial subluxation of the tendon of the long head of the biceps was present in all four cases. No delamination tears occurred on the bursal surface. Only three of the 14 shoulders underwent surgical repair with one confirmation of supraspinatus delamination, one confirmation of a subscapularis tear that had become a full thickness tear 10 months after initial imaging and another interstitial subscapularis delamination that was not identified arthroscopically. Delamination tears occur most often in the

When remediation began at the Weldon Spring Site Remedial Action Project (WSSRAP), there were 41 buildings on site. Twenty-nine of these buildings were ancillary structures and were not used for processing radioactive material. Most of these have been torn down. The remaining 12 buildings were used for uranium and thorium processing or were major support structures, such as the laboratory. Two of the buildings were major processing operations occurred were successfully demolished in February of this year. Demolition of all structures will be complete in September of this year. To give an understanding of the magnitude of the work, the following is a description of the physical characteristics of the green salt building. This building was used to convert brown oxide (UO3) to green salt (UF4), which is the last intermediate step in purifying the mostly yellow cake feed material into uranium metal.

Felicitas Pauss - Physics without borders

With the goal of turning CERN into a truly global laboratory, the Director-General has appointed Felcitas Pauss to the newly created position of Co-ordinator for External Relations. In this interview with the Bulletin she explains how external relations will shape the future of CERN. "At CERN there is already an excellent atmosphere of international collaboration, of working together beyond political boundaries," says Felicitas Pauss, the newly appointed Co-ordinator for External Relations. "This is indeed a remarkable feature of scientific collaborations." When it was founded over 50 years ago CERN had the seemingly impossible task of stitching together a united European particle physics community from countries torn apart by the Second World War. Today this goal of collaboration is just as important, not only within Europe but worldwide. "The particle physics landscape has really changed over the past years," Pauss points out. "As...

Cryptorchidism is defined as maldescensus testis. This means that one or both testicles are not located in the scrotum at six months of age, but abdominal, inguinal or ectopic. Ectopic testes can be localised suprafascially, perineally or crurally. Physiologically, descensus testis is finished...... about 35-40 days after birth in the dog and at the time of birth in the torn. Delayed descent is diagnosed when testis are located in the scrotum at a later point of time. Whereas cryptorchidism in the dog is undoubtedly multifactorial with breed-specific involvement of one or more genes (mono......-/polygenic), epigenetic and environment-associated factors, heredity in the cat is still unclear although an increased incidence is reported in Persians, Ragdolls and European Shorthair. The diagnosis can be confirmed by palpation (in case of inguinal testes) or by ultrasound. GnRH and hCG stimulation tests can be used...

Full Text Available Neste artigo abordamos a relação funcional e afetiva que o sujeito de consumo da sociedade administrada estabelece para com um dos mais bem-sucedidos modelos comerciais da tecnocracia capitalista, o Shopping Center, evidenciando uma espécie de simbiose entre o humano e o material, circunstância que demonstra o efeito sedutor que a estrutura assimiladora do Shopping Center, um genuíno templo de consumo, exerce sobre a subjetividade pessoal do frequentador, dando-lhe a sensação de conforto e segurança que não encontra no mundo exterior. Contudo, por reconhecermos que a sociedade de consumo se fundamenta na alienação da consciência do ser humano, propomos a ressignificação do Shopping Center, de modo a torná-lo um espaço social de politização.

LAS ASOCIACIONES DE MIGRANTES HAITIANOS EN EL ECUADOR: ENTRE DEBILIDAD Y RESISTENCIA

Full Text Available Resumen Las iniciativas asociativas haitianas en Ecuador hay que verlas dentro del contexto generado por el terremoto del año 2010 en Haití. Se trata de una población que se ha visto forzada a migrar, pero que no se la considera dentro de los parámetros de protección de acuerdo a la Convención sobre el Estatuto de los Refugiados de 1951, por lo que permanecen en situación de desprotección por su irregularidad migratoria. En este contexto, hay dos asociaciones haitianas en Quito que han jugado un importante rol especialmente en el ámbito de la asesoría y comunicación, tornándose en espacios de participación cívica. Al ser iniciativas asociativas débiles, peligran su existencia al contar con pocas redes de apoyo institucional.

The Ideological and Political Dimensions of the Anti-Smoking and Anti-Drinking Video Advertisements in the Republic of Moldova.

Stanchevici, Dmitri

2017-06-01

Based on the critical approach in health communication, along with Habermas's theory of legitimation and Ellul's theory of propaganda, this qualitative study analyzes the political and ideological dimensions of the video advertisements used in the 2012 anti-smoking and 2014 anti-drinking campaigns in the Republic of Moldova. This analysis shows that these health videos support male domination and exclusion of the poor and legitimate the current political leadership with its declared pro-European orientation. This study uniquely contributes to the critical approach in health communication by focusing on the post-Soviet context in which statehood and national identity are unstable and societies are torn between the Russian and (post-)Soviet influences on one hand and European aspirations on the other. Drawing on critical scholarship in global health communication, this article calls for greater respect and recognition of Moldova's local culture and definition of health.

Questioning the role of Facebook in maintaining Syrian social capital during the Syrian crisis

Full Text Available The Syrian crisis is considered the ‘world’s single largest crisis for almost a quarter of a century that has the biggest refugee population from a single conflict in a generation’ (UN High Commissioner for Refugees, 2016. The rapid adoption of Facebook among Syrians questions whether it helps in maintaining the social capital of a war-torn nation and a dispersed Syrian population worldwide. Data was collected by means of a Facebook survey from 964 Syrian users. Results indicated that Facebook enhanced social identity and social capital through facilitating communication, collaboration and resource sharing among dispersed Syrians inside and outside the country. However, the offline rift of the nation was extended to Facebook through promoting hate speech among opposed parties. Results of this study may advance the understanding of the role of Facebook on social capital in countries going through similar crisis situations.

The Witness in Contempt: Reflections on Overfamiliarity, Pain and Desecration

Maria Tumarkin

2013-08-01

Full Text Available There are many opportunities for lying and cheating in engaging with, what Susan Sontag called, ‘the pain of others’. One of them is the gradual emergence of the feeling that you know what happened, what it was like to go through it. Yet overfamiliarity can, at times, injure more than contempt or blatant disregard. With so many recent tragedies, the experts who know how it feels and what it’s like, send tropical medications to war-torn continental countries, offer free art therapy classes in place of bread and water, write reports about the ‘atmosphere of fear and uncertainty’ that can neither produce the most negligible of changes nor console even the most naive of souls. It’s possible to counter contempt and indifference with knowledge, laughter and moral courage, but what is the defence against the thick web of assumptions?

A 78 year-old female suffered from vaginal discharge of flatus and stool for 20 years after the radiation therapy for cervical cancer. Digital and endoscopic examination of the rectum and the vagina disclosed a large, short rectovaginal fistula at the level of the cervix. Since laparotomy and low anterior resection of the rectum were impossible, a perineal approach was adopted. After perineal skin incision, the fistula was resected and the defects of the rectum and the vagina were closed. Gracilis muscular flap was anchored between the two closures. Though the closure of the rectal side was torn, her postoperative course was uneventful. Endoscopic examination 24 days after the operation confirmed healing of the dehiscence. The results verified the usefulness of the perineal approach using the gracilis muscular flap as an alternative method to low anterior resection for troublesome radiation induced rectovaginal fistula.

The struggle of giving up personal goals: affective, physiological, and cognitive consequences of an action crisis.

Science.gov (United States)

Brandstätter, Veronika; Herrmann, Marcel; Schüler, Julia

2013-12-01

A critical phase in goal striving occurs when setbacks accumulate and goal disengagement becomes an issue. This critical phase is conceptualized as an action crisis and assumed to be characterized by an intrapsychic conflict in which the individual becomes torn between further goal pursuit and goal disengagement. Our theorizing converges with Klinger's conceptualization of goal disengagement as a process, rather than a discrete event. Two longitudinal field studies tested and found support for the hypothesis that an action crisis not only compromises an individual's psychological and physiological well-being, but also dampens the cognitive evaluation of the respective goal. In Study 3, marathon runners experiencing an action crisis in their goal of running marathons showed a stronger cortisol secretion and a lower performance in the race 2 weeks later. Results are interpreted in terms of action-phase-specific mindsets with a focus on self-regulatory processes in goal disengagement.

Weldon Spring Site Remedial Action Project approach to building dismantlement and demolition

When remediation began at the Weldon Spring Site Remedial Action Project (WSSRAP), there were 41 buildings on site. Twenty-nine of these buildings were ancillary structures and were not used for processing radioactive material. Most of these have been torn down. The remaining 12 buildings were used for uranium and thorium processing or were major support structures, such as the laboratory. Two of the buildings were major processing operations occurred were successfully demolished in February of this year. Demolition of all structures will be complete in September of this year. To give an understanding of the magnitude of the work, the following is a description of the physical characteristics of the green salt building. This building was used to convert brown oxide (UO3) to green salt (UF4), which is the last intermediate step in purifying the mostly yellow cake feed material into uranium metal

Daryl Gordon

2011-01-01

Full Text Available Unprecedented numbers of adult refugee learners are entering ESL classes, many of whom escaped war-torn countries and endured long stays in refugee camps. Research in public health and psychology has documented high levels of depression, anxiety, and posttraumatic stress disorder in refugee populations. Drawing on ethnographic research with Laotian refugee women who experienced pre-settlement trauma during the Vietnam War and interviews with bilingual mental health professionals, this article examines current second language acquisition theories to consider how they elucidate the effect of trauma on second language learning. The article offers cross-cultural perspectives about the impact of trauma on learning and recommendations for working with adult refugee learners who have experienced trauma. Findings have implications for ESL instructors and second language researchers concerned with the impact of pre- settlement experiences on second language acquisition and implications for classroom instruction.

Peacebuilding: assumptions, practices and critiques

Directory of Open Access Journals (Sweden)

Cravo, Teresa Almeida

2017-05-01

Full Text Available Peacebuilding has become a guiding principle of international intervention in the periphery since its inclusion in the Agenda for Peace of the United Nations in 1992. The aim of creating the conditions for a self-sustaining peace in order to prevent a return to armed conflict is, however, far from easy or consensual. The conception of liberal peace proved particularly limited, and inevitably controversial, and the reality of war-torn societies far more complex than anticipated by international actors that today assume activities in the promotion of peace in post-conflict contexts. With a trajectory full of contested successes and some glaring failures, the current model has been the target of harsh criticism and widespread scepticism. This article critically examines the theoretical background and practicalities of peacebuilding, exploring its ambition as well as the weaknesses of the paradigm adopted by the international community since the 1990s.

In zones of violent conflict in the tropics, social disruption leads to elevated child mortality, of which malaria is the leading cause. Understanding the social determinants of malaria transmission may be helpful to optimize malaria control efforts. We conducted a cross-sectional study of healthy children aged 2 months to 5 years attending well-child and/or immunization visits in the Democratic Republic of Congo (DRC). Six hundred and forty-seven children were tested for malaria antigenemia by rapid diagnostic test and the accompanying parent or legal guardian simultaneously completed a survey questionnaire related to demographics, socioeconomic status, maternal education, as well as bednet use and recent febrile illness. We examined the associations between variables using multivariable logistic regression analysis, chi-squared statistic, Fisher's exact test, and Spearman's rank correlation, as appropriate. One hundred and twenty-three out of the 647 (19%) children in the study tested positive for malaria. Higher levels of maternal education were associated with a lower risk of malaria in their children. The prevalence of malaria in children of mothers with no education, primary school, and beyond primary was 41/138 (30%), 41/241 (17%), and 39/262 (15%), respectively (p = 0.001). In a multivariable logistic regression model adjusting for the effect of a child's age and study site, the following remained significant predictors of malaria antigenemia: maternal education, number of children under five per household, and HIV serostatus. Higher maternal education, through several putative causal pathways, was associated with lower malaria prevalence among children in the DRC. Our findings suggest that maternal education might be an effective 'social vaccine' against malaria in the DRC and globally.

By using a pair of tiny current injectors one can create an arbitrary {kappa} discontinuity of the phase in a long Josephson junction (LJJ) and a fractional Josephson vortex (FJV), carrying a fraction {phi}/{phi}{sub 0}={kappa}/2{pi}{<=}1 of the magnetic flux quantum {phi}{sub 0}{approx}2.07 .10{sup -15} Wb, which is pinned at the discontinuity. If a bias current I, exceeds the critical value I{sub c}({kappa}), an integer fluxon is torn off the discontinuity and the LJJ switches to the voltage state. Due to thermal or quantum fluctuations this escape event may occur at I

Large, cold, and unusual molecular cloud in Monoceros

Observations of the J = 1 → 0 rotational transition of CO near the galactic plane in Monoceros (lroughly-equal216 0 ) reveal a molecular cloud with unusually low peak CO temperatures (T/sub R/ -1 ) typical of much warmer clouds. At the assumed distance of 3 kpc, the cloud is large (250 x 100 pc), has a mass of 7-11 x 10 5 M/sub sun/, and is well removed from the galactic midplane (130 pc). Except for a possible H II region, all the signs of star formation usually shown by clouds of comparable mass are missing. The cloud, unlike cloud complexes of similar size, is a single, continuous object that apparently has not been torn apart by star formation. Clouds with such properties are rare in the Galaxy; only one or two similar objects have been found. We discuss the possibility that the cloud is young and not yet forming stars but will evolve into a typical cloud complex once star formation begins

High re-tear rate is reported after rotator cuff repair in large and massive tear cases. Previously, we reported that 15% of patients after rotator cuff repair showed re-tear in MRI findings. In this study, 116 consecutive rotator cuff repaired patients who had been operated arthroscopically since 2003 were evaluated for size, torn site, fixation methods, mobility, and tendon quality. In addition, rehabilitation methods and occupation after revision were also evaluated. There were four patients who underwent re-operation. Rotator cuff repairs by revision surgery failed mechanically due to two reasons: the main factor of failure was suture material breakage in three cases and the second was tendon pulling through sutures in one case. The lack of thread strength was suggested. In addition, it is important to pull cuff stump to greater tubercle without excessive tension. Of re-operated cases, three engaging in manual labor suffered large and massive tear. In two cases, premature return to manual labor suggested cause of re-tear. (author)

Sixty years ago, a handful of European scientists saw their dream of cooperation come true. Thanks to their efforts, nations which had been torn apart during the war came together to create the first European scientific organisation. Having lived through bombing, destruction, death and genocide, they regarded European integration as vital to the survival of their respective nations. Their goal was for their domain to participate in the general efforts towards reconstruction and peace.  They successfully rose to the challenge and CERN became one of the world’s most prestigious research laboratories. Among these early activists was a diplomat, François de Rose. At the ripe old age of 103, the former French ambassador is the last surviv...

1988-01-01

The accuracy of MR imaging in the detection of ligamentous injury was evaluated in 29 patients (24 male, five female) with spinal injury resulting in fractures (n=27), evidence of instability (n=11), or neurologic deficit (n=2). MR examinations were performed acutely (average, 7.5 days posttrauma) with T1- and T2-weighted imaging and were blindly evaluated. Subsequently, plain films (n=27), tomograms (n=10), and CT scans (n=22) were evaluated. Eighteen patients underwent surgery. Fourteen patients had torn ligaments as indicated by clinical and surgical findings. MR imaging demonstrated ligament damage in 13. One case imaged 40 days following trauma was not detected. No patients with intact ligaments had evidence of ligamentous damage on MR images. MR imaging demonstrated retropulsed fractures in six patients in whom the posterior longitudinal ligament was intact but displaced from the vertebra. MR imaging was more reliable than radiography and CT for detection of ligamentous injury, and T2- weighted sequences are essential in such cases

Fractured Identity: A Framework for Understanding Young Asian American Women's Self-harm and Suicidal Behaviors.

2014-01-01

Despite the high suicide rate among young Asian American women, the reasons for this phenomenon remain unclear. This qualitative study explored the family experiences of 16 young Asian American women who are children of immigrants and report a history of self-harm and/or suicidal behaviors. Our findings suggest that the participants experienced multiple types of "disempowering parenting styles" that are characterized as: abusive, burdening, culturally disjointed, disengaged, and gender-prescriptive parenting. Tied to these family dynamics is the double bind that participants suffer. Exposed to multiple types of negative parenting, the women felt paralyzed by opposing forces, caught between a deep desire to satisfy their parents' expectations as well as societal expectations and to simultaneously rebel against the image of "the perfect Asian woman." Torn by the double bind, these women developed a "fractured identity," which led to the use of "unsafe coping" strategies. Trapped in a "web of pain," the young women suffered alone and engaged in self-harm and suicidal behaviors.

HIV/AIDS, childhood and governance: sundering the bonds of human society.

Science.gov (United States)

Barnett, Tony

2005-12-01

There is a disharmonious resonance between the length of HIV infection in the individual human host and the length of a human generation. In brief, an infected person may have children, these may be orphaned and grow up to become infected, and afterwards they themselves may have children, who can be orphaned in turn. Hence, a basic unit of social structure in most human societies, the three-generation bond between grandparents, parents and the current generation - and on into the future - is repeatedly torn apart in the absence of treatment, a vaccine or behaviour change. This situation should be read against the threat of growing viral resistance. Certain implications of these processes for the future are outlined and discussed. The paper notes the uncertain future confronting societies that already have a relatively high number of orphans, and considers some otherwise unexpected possibilities, as well as the dangers of assuming that large-scale orphaning necessarily leads to social unrest and disorder.

One way and the other: the bidirectional relationship between ambivalence and body movement.

Prior research exploring the relationship between evaluations and body movements has focused on one-sided evaluations. However, people regularly encounter objects or situations about which they simultaneously hold both positive and negative views, which results in the experience of ambivalence. Such experiences are often described in physical terms: For example, people say they are "wavering" between two sides of an issue or are "torn." Building on this observation, we designed two studies to explore the relationship between the experience of ambivalence and side-to-side movement, or wavering. In Study 1, we used a Wii Balance Board to measure movement and found that people who are experiencing ambivalence move from side to side more than people who are not experiencing ambivalence. In Study 2, we induced body movement to explore the reverse relationship and found that when people are made to move from side to side, their experiences of ambivalence are enhanced.

How Traumatic Violence Permanently Changes Shopping Behavior.

2016-01-01

Traumatic experiences - such as combat, living in a conflict country or war-torn nation, or experiencing a violent crime or natural disaster - change social relationships and may also influence a life-time of consumer relationships with brands and shopping. Our focus on this previously overlooked area is centered on an analysis of the long-term shopping habits of 355 combat veterans. We show that those who experienced heavy trauma (e.g., heavy combat) exhibited similar disconnection from brands as others have experienced in social relationships. They became more transactional in that they were more open to switching brands, to trying new products, and buying the least expensive alternative (p buying brands even when they cost more (p < 0.00). Trauma, such as combat, may change one's decision horizon. Functionality and price become more important, which is consistent with the idea that they are more focused on the present moment than on building on the past or saving for the future.

Review: Modelling of meniscus of knee joint during soccer kicking

2013-12-01

Knee is a part of the body that located between thigh and shank is one of the most complicated and largest joints in the human body. The common injuries that occur are ligaments, meniscus or bone fracture. During soccer games, the knee is the most critical part that will easily injure due to the shock from an external impact. Torn meniscus is one of the effects. This study will investigate the effect towards the meniscus within the knee joint during soccer ball kicking. We conduct a literary review of 14 journals that discuss the general view of meniscus and also soccer kicking. The selected topics for this review paper are meniscal function, meniscal movement, meniscal tears and also instep kick. As a finding, statistics show that most meniscal tears (73%) occurred in athletes who were soccer players, basketball players or skiers. The tear is frequently happening at the medial side rather than lateral side with a percentage of 70%.

THE “VÍDEO PARTICIPATIVO” (PARTICIPATORY VIDEO AS A WAY TO REFLECT AND SELF-REFLECT ON IMAGE AND IDENTITY OF REEMERGENT INDIANS FROM BRAZIL’S NORTHEAST

Directory of Open Access Journals (Sweden)

Peter Anton Zoettl

2011-12-01

Full Text Available Crises and change have affected the Brazilian indigenous population for more than 500 years. While for centuries their struggle against colonialism and the dominant national society had resulted in an ever shrinking population, the last decades have seen an unfamiliar phenomenon: the rise of “new” indigenous tribes in areas which, by the state and public opinion, were long considered as “acculturated”. These “reemerging” Indians, in their pursuit of both legal and actual recognition by authorities and their fellow Non-Indian citizens, face and undergo a peculiar re-elaboration of their “image” as Indians, being torn between romantic ideas of Indianness, and the demands of full integration within national society. Drawing on recent fieldwork experience in northeastern Brazil, the paper discusses how the visual-anthropological method of “participatory video” can be used as a means of reflecting on, and catalyzing, processes of individual and group identity formation of minority groups within a local-global context.

Magnetic resonance imaging of injuries to the ankle joint: can it predict clinical outcome?

1997-02-01

To predict clinical outcome after ankle sprains on the basis of magnetic resonance (MR) findings. Twenty-nine consecutive patients (mean age 32.9 years, range 13-60 years) were examined clinically and with MR imaging both after trauma and following standardized conservative therapy. Various MR abnormalities were related to a clinical outcome score. There was a tendency for a better clinical outcome in partial, rather than complete, tears of the anterior talofibular ligament and when there was no fluid within the peroneal tendon sheath at the initial MR examination (P = 0.092 for either abnormality). A number of other MR features did not significantly influence clinical outcome, including the presence of a calcaneofibular ligament lesion and a bone bruise of the talar dome. Clinical outcome after ankle sprain cannot consistently be predicted by MR imaging, although MR imaging may be more accurate when the anterior talofibular ligament is only partially torn and there are no signs of injury to the peroneal tendon sheath.

Radial head button holing: a cause of irreducible anterior radial head dislocation

''Buttonholing'' of the radial head through the anterior joint capsule is a known cause of irreducible anterior radial head dislocation associated with Monteggia injuries in pediatric patients. To the best of our knowledge, no report has described an injury consisting of buttonholing of the radial head through the annular ligament and a simultaneous radial head fracture in an adolescent. In the present case, the radiographic findings were a radial head fracture with anterior dislocation and lack of the anterior fat pad sign. Magnetic resonance imaging (MRI) clearly demonstrated anterior dislocation of the fractured radial head through the torn annular ligament. The anterior joint capsule and proximal portion of the annular ligament were interposed between the radial head and capitellum, preventing closed reduction of the radial head. Familiarity with this condition and imaging findings will aid clinicians to make a proper diagnosis and fast decision to perform an open reduction. (orig.)

The New and the Future Look of the Economy

Full Text Available The global financial situation and our future economy remain vital concerns for us all. As a result, the government and the business community have to stimulate the economy and give it new dimensions. Virtually everyone agrees on the importance of the economy, but no consensus has or is expected to be reached soon as to the definition of the economy. Economy as a “discipline”' is a concept torn apart by current economic crisis, where fierce competition, greed and consumerism will neither solve the crisis in progress nor will they rehabilitate the economy. It is true that the current economic crisis and the times of slower economic growth that will inevitably follow are old system-related symptoms of the excesses and the recklessness accumulated in time at global level, for which reason we see ourselves forced now to reconsider the options that are lay ahead and outline a clear future perspective.

The coastal fishes and fisheries of the Socotra Archipelago, Yemen.

The Socotra Archipelago is situated in the Gulf of Aden where tropical and "pseudo-temperate" conditions combine to create a unique marine ecosystem. The diversity, ecology, productivity and fisheries of the coastal fish assemblages are still relatively understudied and no update of the scientific knowledge existed. The islands support unique coastal and coral-associated fish assemblages in spite of the limited biogenic reef frameworks. Fish diversity is the highest among comparable Arabian eco-regions, and fish biomass productivity high too by Indian Ocean standards. The production of the once traditionally-managed small-scale fishery is severely declining and whether it is sustainable nowadays is extremely doubtful. At a time when Yemen is torn apart by a severe political and humanitarian crisis it is timely to review and update the current state of knowledge for scientists and managers, and thereby ease access to existing information, facilitating follow-on studies and evidence-based conservation and fisheries management.

Full Text Available Globalization is not a new concept, as it would be. It has a torn history of acceptances andrejections, starting with the nineteenth century. Globaphobia and globaphilia are two terms thateloquently justify the pro and anti struggle against this phenomenon, which is not yet understoodby many politicians, but which takes full advantage of it, as economist Guillermo de la Dehesasays. In order to understand the principles of globalization and its effects, we must judge in termsof benefits and losses in the historical and economic context of the last decades, struck by wars, bythe cultural and social decline, by the closure of some states in the communist blocs. It is only afterunderstanding the events that we can dissect what is happening today in Europe and globally. Atthe end of the 20th century and the 21st century, humankind continues globalization on segments,allocating the greatest tribute to education through continuous training, study and practice.

MRI findings in bucket-handle tears of the triangular fibrocartilage complex

International Nuclear Information System (INIS)

Jose, Jean; Arizpe, Azael; Chen, David; Barrera, Carlos M.; Ezuddin, Nisreen Shabbir

2018-01-01

The triangular fibrocartilage complex (TFCC) is an intricate ligamentous and cartilaginous structure that helps transmit axial load across the wrist, and provide stability to the ulnocarpal and distal radioulnar joints (DRUJ). Because the blood supply to the TFCC varies depending on location, certain types of tears are more amenable to surgical repair than others. Since Palmer proposed his classification system of TFCC tears in 1989, only 1 case of a ''bucket-handle'' type tear has been reported. In this article, we describe two new cases of bucket-handle tears of the TFCC. In both cases, the torn fragment was displaced into a previously undescribed location (intra-articular DRUJ and prestyloid recess). Because this type of injury pattern has not been previously well characterized in the literature and such cases rarely reported, MRI findings have not been fully described and its implications on clinical management have largely yet to be determined.

Ma, Jinjin; Smietana, Michael J.; Kostrominova, Tatiana Y.; Wojtys, Edward M.; Larkin, Lisa M.

2012-01-01

The anterior cruciate ligament (ACL), a major stabilizer of the knee, is commonly injured. Because of its intrinsic poor healing ability, a torn ACL is usually reconstructed by a graft. We developed a multi-phasic, or bone–ligament–bone, tissue-engineered construct for ACL grafts using bone marrow stromal cells and sheep as a model system. After 6 months in vivo, the constructs increased in cross section and exhibited a well-organized microstructure, native bone integration, a functional enthesis, vascularization, innervation, increased collagen content, and structural alignment. The constructs increased in stiffness to 52% of the tangent modulus and 95% of the geometric stiffness of native ACL. The viscoelastic response of the explants was virtually indistinguishable from that of adult ACL. These results suggest that our constructs after implantation can obtain physiologically relevant structural and functional characteristics comparable to those of adult ACL. They present a viable option for ACL replacement. PMID:21902608

Genesis of the constitutionality and statehood of the Republic of Srpska: Constitutional acts in Bosnia and Herzegovina in 1990 and 1991

Full Text Available Constitutional (statehood or foundation acts are those on which the establishment of a state is founded. These acts determine its statehood entities (part-owners of the state in which the foundations of state organization are defined. All other authorities (legislative, executive and administrative, and judicial are extracted from constitutional acts which are synthesized in the Constitution as the highest political and legal act. Constitutional acts in Bosnia and Herzegovina in the abovementioned period influenced each other as the domino effect, since one act caused the adoption of another, thus, each state-building act had the cause and consequence feature. Constitutional act of representatives of a nation caused the adoption of a similar act among representatives of another nation, which resulted in the statehood authority losing its unique character and being 'torn apart' into three national state-building authorities. In this text we mention the basic constitutional acts preceding the establishment of the Assembly of the Serb People in Bosnia and Herzegovina.

Six decades of educational multilateralism in a globalising world: The history of the UNESCO Institute in Hamburg

Science.gov (United States)

Elfert, Maren

2013-07-01

Created in 1945 as a specialised agency of the United Nations (UN), the United Nations Educational, Scientific and Cultural Organization (UNESCO) was given, among other mandates, the task of reconstructing education systems devastated during the Second World War. UNESCO, in turn, and after some debate about an engagement in Germany, founded the UNESCO Institute for Education (UIE) in Hamburg in 1952. This paper traces the development of an institute which was founded to contribute to social renewal in war-torn Germany and Europe, functioned as a mediator between Western and Eastern countries during the Cold War and later shifted its geographical focus to developing countries. The institute was instrumental in conceptualising lifelong learning as a global educational paradigm, as well as in shaping the shift from education to learning and the concept of literacy as a "continuum". The author is particularly interested in the nature of the institute's niche which secured its survival in the uncertain domain of educational multilateralism in the past six decades.

Although kidnapping is common in war-torn countries, there is little research examining its psychological effects. Iraqi refugees (N = 298) were assessed upon arrival to the U.S. and 1 year later. At arrival, refugees were asked about prior trauma exposure, including kidnapping. One year later refugees were assessed for posttraumatic stress disorder (PTSD) and major depression disorder (MDD) using the SCID-I. Individual resilience and narratives of the kidnapping were also assessed. Twenty-six refugees (9 %) reported being kidnapped. Compared to those not kidnapped, those who were had a higher prevalence of PTSD, but not MDD, diagnoses. Analyses examining kidnapping victims revealed that higher resilience was associated with lower rates of PTSD. Narratives of the kidnapping were also discussed. This study suggests kidnapping is associated with PTSD, but not MDD. Additionally, kidnapping victims without PTSD reported higher individual resilience. Future studies should further elucidate risk and resilience mechanisms.

The Places of Memory in a Square of Monuments: Conceptions of Past, Freedom and History at Szabadság Tér

Erik Thorstensen

2012-01-01

Full Text Available In this paper I try to approach contemporary Hungarian political culture through an analysis of the history of changing monuments at Szabadság Tér in Budapest. The paper has as its point of origin a protest/irredentist monument facing the present Soviet liberation monument. In order to understand this irredentist monument, I look into the meaning of the earlier irredentist monuments under Horthy and try to see what monuments were torn down under Communism and which ones remained. I further argue that changes in the other monuments also affect the meaning of the others. From this background I enter into a brief interpretation of changes in memory culture in relation to changes in political culture. The conclusions point toward the fact that Hungary is actively pursuing a cleansing of its past in public spaces, and that this process is reflected in an increased acceptance of political authoritarianism.

Ansari, M. Z.; Mujeeb, A.; Nirala, A. K.

2018-06-01

We report on the application of an optical imaging technique, the biospeckle laser, as a potential tool to assess biological and medicinal plant leaves. The biospeckle laser technique is a non-invasive and non-destructive optical technique used to investigate biological objects. Just after their removal from plants, the torn leaves were used for biospeckle laser imaging. Quantitative evaluation of the biospeckle data using the inertia moment (IM) of the time history speckle pattern, showed that the IM can be utilized to provide a biospeckle signature to the plant leaves. It showed that leaves from different plants can have their own characteristic IM values. We further investigated the infected regions of the leaves that display a relatively lower biospeckle activity than the healthy tissue. It was easy to discriminate between the infected and healthy regions of the leaf tissue. The biospeckle technique can successfully be implemented as a potential tool for the taxonomy of quality leaves. Furthermore, the technique can help boost the quality of ayurvedic medicines.

2010-01-01

Full Text Available Discoid meniscus is the commonest anatomical aberration of the knee joint, among rare cases such as bilateral separated lateral meniscus, accessory lateral meniscus, partial deficiency of the lateral meniscus and double-layered lateral meniscus. An 11-year- old girl presented with history of chronic pain in her right knee for the last 6 months. The problem disturbed her involvement in the sport activities at school. Clinical examination revealed a clicking sensation on knee extension with lateral joint line tenderness. Magnetic resonance imaging (MRI of her right knee showed torn posterior horn of lateral meniscus. Arthroscopy examination revealed a discoid meniscus with absence posterior horn. Posterior horn deficient discoid meniscus is a rare form of a congenital meniscus anomaly. We as clinicians believe that the abnormal shaped meniscus may pose a diagnostic challenge clinically and radiologically. Presentation of this case may be beneficial for orthopaedicians in their daily clinical practice.

Plans for first oil production revived in two Sudanese fields

Anon.

1993-01-01

A Vancouver, British Columbia, independent and its Sudanese partner have filed a development plan with the government of Sudan to produce an initial 40,000 b/d from Heglig and Unity oil fields in Sudan. Arakis Energy Corp., and the private Sudanese company State Petroleum Corp. (SPC) want to begin the first commercial hydrocarbon production in the destitute, war torn country. They are picking up where Chevron Corp. left off after years of grappling with an ambitious, costly - and ultimately futile - effort to export crude-oil from Sudan. After finding almost 300 million bbl of oil in Sudan during the early 1980s, Chevron scuttled a $2 billion project to export 50,000 b/d of Sudanese crude in 1986. It drilled 90 wells and sank more than $1 billion into the project. But it dropped the plan, citing the 1986 collapse of oil prices and concerns over security after repeated guerrilla attacks delayed work. The paper details the project

Statement of nuclear incidents at nuclear installations

International Nuclear Information System (INIS)

1993-10-01

Three incidents were reported in April-June 1993. The first was on the British Nuclear Fuel plc (BNFL) site at Sellafield and concerned leakage of 0.5 TBq of alpha activity from plutonium contaminated waste stored in a steel drum. This was subsequently double contained and moved so it could be inspected regularly. No contamination of personnel occurred. The second concerned the leakage of thorium liquor from a pipe at the UKAEA's Thorium reprocessing plant at Dounreay. Two temporary repairs were made and no personnel were contaminated. The third was at the Sellafield site where a small quantity (5 mls) of plutonium containing liquor had leaked from a package and released alpha activity. The bags were temporary containment of engineering debris which may have had sharp edges. The bags had been piled up and one of the bags had torn. Recommendations were made following inquiries into each of the incidents to improve procedures and prevent similar incidents occurring. (UK)

This paper reports shoulder MR examinations of 250 patients retrospectively evaluated and correlated with surgical/arthrographic results in 68 patients and with clinical data in all for assessment of the signal pattern and the configuration of rotator cuff lesions. MR-histopathologic evaluation of the supraspinatus tendon of 8 cadaver shoulders was also correlated with these findings. MR imaging had a sensitivity of 92% in the diagnosis of cuff tears. The most common and accurate criterion for a tear was a tendinous defect, characterized by intense signal on T2-weighted images; less often the torn region consisted of an extremely degenerated and attenuated tendon or was obscured by scar. Presence of secondary findings was mandatory for diagnosis in the latter group. Signal pattern associated with tendonitis varied, and in some simulated that of tendon degeneration (fatty infiltration and fibrillation) or cellular proliferation observed on anatomic specimens. Associated tendinous enlargement and subacromial-subdeltoid bursitis in these patients best correlated with the severity of clinical and surgical findings

Background: In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the 'bridging sign', which has not been previously described. Purpose: To describe the 'bridging sign' on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear. Material and Methods: Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled. The medical records of the 29 patients were retrospectively reviewed for the duration of shoulder pain, rotator cuff tears, and associated arthroscopic findings: biceps tendon abnormality and superior glenoid labral tear. Then, preoperative shoulder MR images were retrospectively reviewed for the presence or absence of the 'bridging sign' and associated MR findings: periarticular fluid and fatty atrophy of the supraspinatus and subscapularis muscles. The type of rotator cuff tear associated with the 'bridging sign' was assessed and the sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of a certain type of rotator cuff tear were calculated. Associated arthroscopic and MR findings and mean duration of the shoulder pain between the patients with and without the 'bridging sign' were compared. Results: The 'bridging sign' was seen in 17 of 29 patients and corresponded to a complex of the torn and superomedially retracted subscapularis tendon, coracohumeral ligament, and superior glenohumeral ligament, adhered to the anterior margin of the torn supraspinatus (SSP) tendon on arthroscopy. All patients with the 'bridging sign' had combined full-thickness tear (FTT) of the cranial 1/2 portion of the subscapularis tendon and anterior 1/2 portion of the SSP tendon. The sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of combined FTTs of

Morphological changes in skeletal muscle after irradiation with nano- and microsecond laser pulses

International Nuclear Information System (INIS)

Gratzl, T.

1995-09-01

For therapeutic application of laser light it is necessary to minimize defects in the nonirradiated tissue. These defects depend on the primary mechanism of interaction between tissue and laser light. Three experiments were performed to distinguish between mechanical and thermal effects of nano- and microsecond laser pulses in skeletal muscle of the rat. The light, transmission and scanning electron microscopes were used. Laser pulses were applied to unfixed muscle immediately after dissection. A Nd-YAG laser (wavelength 1064 nm; pulse repetition rate 10s -1 ; beam diameter 9 mm; pulse-energy 340 mJ) was used in the flashlamp-pulsed mode (pulse duration 100 μs) and the Q-switched mode (pulse duration 8 ns). When focused 2 mm below the tissue surface in the μs-experiments (100 μs) 200 laser pulses produced a small crater. The defective region after irradiation can be divided under the light microscope into four zones surrounding the crater. The innermost zone I showed vacuoles in the intensively stained muscle cells. In the next zone II the myofibrils were displaced and torn apart. Zone III is a sharply bordered, intensively stained region. The muscle cells in zone IV are contracted. All these tissue effects were thermally induced. When focused 4 mm below the tissue surface, the μs-pulses produced an expansion of the irradiated region, while leaving the surface intact. Here, only the features of zones II to IV were seen. In the spallation experiments muscle samples were placed on metal foil. The foil itself was dipped into water. A single laser pulse (8 ns) was directed at the underside of the foil. Only the pressure wave passed through the sample and was reflected on the muscle surface in a stretch wave. Tissue damage by mechanical action occurs inside the sample. Muscle fibers are torn apart and myofibrils are displaced. In the ns-experiments the mechanical action of a single ns pulse (8 ns) produced a crater. Only zones I and IV developed. With 50 to 100

forearm.1,9 Type II injuries involve a torn AC ligament, disrupting the AC joint. The AC joint appears widened on radiographs.1,9 The AC and CC ligaments are disrupted in type III injuries with an increased CC distance of 25%-100% on plain films.1,10 In addition to torn AC and CC ligaments, the clavicle is posteriorly displaced in a type IV injury. Because the AP film may not reveal the posterior displacement of the clavicle, the axillary view is vital for correct classification of type IV injuries.1 A type V injury involves disruption of the AC and CC ligaments as well as torn muscle attachments of the trapezius and deltoid on the clavicle and scapula, leading to greater AC joint displacement on radiographs. The CC distance appears 100%-300% greater than normal.1,10 Type VI injuries are caused by a direct blow to the superior surface of the clavicle resulting in inferior displacement. On X-ray, the lateral end of the clavicle is inferior to the acromion and coracoid processes in Type VI injuries.1 Treatment for types I, II, and III is conservative, which consist of analgesics, non-steroidal anti-inflammatory drugs (NSAIDs, and progressive range of motion exercises.11 Patients with type III injuries who fail conservative management are referred for operative repair.11,12 Type IV, V, and VI injuries require orthopedic consult and surgical management. Type IV injuries are treated with closed reduction to type III, followed by the treatment regimen for type III injuries.11 Like type III injuries, if conservative management of type IV injuries is unsuccessful, surgical management should follow.11 Topics: Acromioclavicular joint, Rockwood classification, shoulder injury

Simulation of High-Latitude Hydrological Processes in the Torne-Kalix Basin: PILPS Phase 2(e). 3; Equivalent Model Representation and Sensitivity Experiments

The Project for Intercomparison of Land Surface Parameterization Schemes (PILPS) Phase 2(e) showed that in cold regions the annual runoff production in Land Surface Schemes (LSSs) is closely related to the maximum snow accumulation, which in turn is controlled in large part by winter sublimation. To help further explain the relationship between snow cover, turbulent exchanges and runoff production, a simple equivalent model-(SEM) was devised to reproduce the seasonal and annual fluxes simulated by 13 LSSs that participated in PILPS Phase 2(e). The design of the SEM relates the annual partitioning of precipitation and energy in the LSSs to three primary parameters: snow albedo, effective aerodynamic resistance and evaporation efficiency. Isolation of each of the parameters showed that the annual runoff production was most sensitive to the aerodynamic resistance. The SEM was somewhat successful in reproducing the observed LSS response to a decrease in shortwave radiation and changes in wind speed forcings. SEM parameters derived from the reduced shortwave forcings suggested that increased winter stability suppressed turbulent heat fluxes over snow. Because winter sensible heat fluxes were largely negative, reductions in winter shortwave radiation imply an increase in annual average sensible heat.

Translational Eschatology, Death, and the Absence of God in Rajiv Joseph’s Bengal Tiger at the Baghdad Zoo

2013-07-01

Full Text Available This essay considers Rajiv Joseph’s play Bengal Tiger at the Baghdad Zoo and investigates how it features the complex processes of translation by portraying a translator working in war-torn Iraq during the American occupation of the country. Through an analysis of Jacques Derrida’s theories of mourning and translation, it illustrates how the playwright connects translation both to eschatological thinking and to the capacity to speak to/for the dead; the play emphasizes death and translation as in-between states where characters explore aspects of their lives they could not access when alive, and develop skills that allow them to ‘translate’ themselves in different linguistic and cultural contexts. Through an analysis of the translator as cultural hero and ‘stand-in’ for God, this essay equates translation with post-secular theological inquiry, and looks at linguistic and cultural translations as acts of faith in which the emergence of the new text is both always in the process of manifesting itself and always predicated on the ashes of the original.

Arthroscopic reconstruction of the anterior cruciate ligament (ACL) using autografts or allografts is a common surgical procedure, particularly in young athletes. Although the procedure has excellent success rates, complications such as mechanical impingement, graft rupture, and arthrofibrosis can occur, often necessitating additional surgery. Magnetic resonance (MR) imaging has become a valuable tool in evaluating complications after ACL reconstruction. We report two cases of ACL reconstruction complicated by arthroscopically proven partial graft tears. In both cases the torn anterior graft fibers were flipped into the intercondylar notch, mimicking anterior arthrofibrosis, i.e., a ''cyclops lesion,'' on MR imaging. Careful review of the direction of graft fibers on MR imaging in the ''pseudocyclops'' lesions can help differentiate these partial tears from the fibrosis of a true cyclops. The ''pseudocyclops'' lesion is a previously undescribed MR imaging sign of partial ACL graft tear. Larger studies are required to determine the sensitivity and specificity of the sign, as well as the clinical importance of these partial graft tears. (orig.)

Conservation efforts are only as sustainable as the social and political context within which they take place. The weakening or collapse of sociopolitical frameworks during wartime can lead to habitat destruction and the erosion of conservation policies, but in some cases, may also confer ecological benefits through altered settlement patterns and reduced resource exploitation. Over 90% of the major armed conflicts between 1950 and 2000 occurred within countries containing biodiversity hotspots, and more than 80% took place directly within hotspot areas. Less than one-third of the 34 recognized hotspots escaped significant conflict during this period, and most suffered repeated episodes of violence. This pattern was remarkably consistent over these 5 decades. Evidence from the war-torn Eastern Afromontane hotspot suggests that biodiversity conservation is improved when international nongovernmental organizations support local protected area staff and remain engaged throughout the conflict. With biodiversity hotspots concentrated in politically volatile regions, the conservation community must maintain continuous involvement during periods of war, and biodiversity conservation should be incorporated into military, reconstruction, and humanitarian programs in the world's conflict zones. ©2009 Society for Conservation Biology.

Full Text Available Background: The main purpose of this study was to analyze and assess the development level of health services in Kermanshah province from the perspective of social justice in 2010. Methods: The data extracted from the statistical yearbooks in Statistical Center of Iran and Governor's House in Kermanshah Province were studied by Division by Mean and Principal Component Methods in the framework of GIS, SPSS and Excel software using thirteen indicators of access to health. Results: Findings indicated that, based on the composite index gained, Kermanshah, Qasr-e Shirin and Paveh cities were the most advantaged in terms of a range of health indicators and Salas Babajani, Ravansar and Dalaho were the most disadvantaged cities. Conclusion: Factors such as lack of spatial planning perspective, special concern for the provision of health services in war-torn cities and motivation to work in the hometown, have affected this issue. Thus, the data indicate lack of balance and proportion of the quantity and distribution of health services to the population of the cities as well as inequality in citizens’ access to the civil welfare.

Delayed Collapse of Wooden Folding Stairs

Krentowski, Janusz; Chyzy, Tadeusz

2017-10-01

During operation of folding stairs, a fastener joining the ladder hanger with the frame was torn off. A person using the stairs sustained serious injury. In several dozen other locations similar accidents were observed. As a result of inspections, some threaded parts of the screws were found in the gaps between the wooden elements of the stairs’ flaps. In the construction a hatch made of wooden strips is attached to an external frame by means of metal hangers. Laboratory strength tests were conducted on three samples made of wooden elements identical to the ones used in the damaged stairs. Due to complex load distribution mechanism acting on the base of the structure, a three-dimensional FEM model was created. An original software was used for calculations. Five computational model variants were considered. As a result of the numerical analyses, it was unquestionably shown that faulty connections were the cause of the destruction of the stairs. The weakest link in the load transmission chain were found to have been the screws connecting the hatch board with the hangers.

While the Sphnix’s punishment of being torn asunder and devoured may at least seem quick and to the point, would the efforts of being part of a new endeavor somehow be more inhumane.

Guilty but good: defending voluntary active euthanasia from a virtue perspective.

Science.gov (United States)

Begley, Ann Marie

2008-07-01

This article is presented as a defence of voluntary active euthanasia from a virtue perspective and it is written with the objective of generating debate and challenging the assumption that killing is necessarily vicious in all circumstances. Practitioners are often torn between acting from virtue and acting from duty. In the case presented the physician was governed by compassion and this illustrates how good people may have the courage to sacrifice their own security in the interests of virtue. The doctor's action created huge tensions for the nurse, who was governed by the code of conduct and relevant laws. Appraising active euthanasia from a virtue perspective can offer a more compassionate approach to the predicament of practitioners and clients. The tensions arising from the virtue versus rules debate generates irreconcilable difficulties for nurses. A shift towards virtue would help to resolve this problem and support the call for a change in the law. The controversial nature of this position is acknowledged. The argument is put forward on the understanding that many practitioners will not agree with the conclusions reached.

Innerarity and Immunology: Difference and Identity in selves, bodies and communities

Germán Bula

2013-06-01

Full Text Available Daniel Innerarity’s Ethics of Hospitality highlights a tension in both communities and individuals between embracing difference and protecting identity, while recognizing that difference is constitutive of identity (the fear that dominates contemporary society is above all a fear of difference, of contamination. This dynamical relation between difference and identity can be seen in the workings of the human immune system, as explained by Chilean biologist and philosopher Francisco Varela: the immune system is a process of perpetual construction of bodily identity through self-referential cognition and distinction between self and non-self. This similarity allows for interesting analogies: for example, a society torn apart by xenophobia and chauvinism can be seen as analogous to a body ravaged by an autoimmune disease such as lupus. With the working hypothesis that the similarities respond to what Stafford Beer calls “systemic invariance”,   this paper explores the similarities between the activity of the immune system and the relation between identity and difference in the work of Innerarity.

Comparison of job and career satisfaction between women physicians and women academicians at the American University of Beirut.

2006-01-01

This study assesses the level of job and career satisfaction, work, social life and child care conflict of full time female academic physicians, and compares it with full time female non medical academicians at the American University of Beirut. The authors show that female physicians were significantly more satisfied with resources and income than non physicians. Both groups were satisfied with their job in general, yet less of the non medical academicians were satisfied with the career progress. Furthermore, despite the fact that both categories, if given the choice, would go again for the same major and the same career, yet less of the physicians would advise a friend to follow the same career. There is minimal conflict between social life and work; and being married and having children did not affect the satisfaction level except for the fact of feeling more torn between the demands of work and personal life. Several interpretations are exposed in order to explain the findings, as well as the implications of the study.

Full Text Available An 8-year-old male Jack Russell crossbreed dog was admitted to our hospital with dyspnoea and shock following a dog-bite injury on the ventral neck. Radiographs revealed subcutaneous emphysema and bilateral thyrohyoid bone fractures. Intra-operatively, rupture of both sternohyoid muscles, both hyoepiglotticus muscles, both thyrohyoid muscles and a partial cranial rupture of the superficial sphincter colli muscle were detected. Part of the epiglottis was detached from the thyroid cartilage. The patient’s severed muscles and torn epiglottis were reattached using a simple interrupted suture pattern. Hyoepiglotticus muscles could not be identified. The bilateral thyrohyoid bone fractures were repaired with intraosseous wire suture. A temporary tracheostomy tube and an esophageal feeding tube were placed postoperatively. The dog was discharged after 8 days, re-examined at 2 and 6 months and laryngeal and pharyngeal function were evaluated as normal. To the authors’ knowledge, this is the first report of a dog that presented with laryngeal trauma with hyoid bone fracture and acute dyspnea who underwent surgical treatment resulting in an acceptable outcome.

Falling walls

CERN Multimedia

It was 20 years ago this week that the Berlin wall was opened for the first time since its construction began in 1961. Although the signs of a thaw had been in the air for some time, few predicted the speed of the change that would ensue. As members of the scientific community, we can take a moment to reflect on the role our field played in bringing East and West together. CERN’s collaboration with the East, primarily through links with the Joint Institute for Nuclear Research, JINR, in Dubna, Russia, is well documented. Less well known, however, is the role CERN played in bringing the scientists of East and West Germany together. As the Iron curtain was going up, particle physicists on both sides were already creating the conditions that would allow it to be torn down. Cold war historian Thomas Stange tells the story in his 2002 CERN Courier article. It was my privilege to be in Berlin on Monday, the anniversary of the wall’s opening, to take part in a conference entitled &lsquo...

Background Rotator cuff repair aims to reattach the torn tendon to the greater tuberosity footprint with suture anchors. The present study aimed to assess the diagnostic accuracy of ultrasound in predicting rotator cuff tear repairability and to assess which sonographic and pre-operative features are strongest in predicting repairability. Methods The study was a retrospective analysis of measurements made prospectively in a cohort of 373 patients who had ultrasounds of their shoulder and underwent rotator cuff repair. Measurements of rotator cuff tear size and muscle atrophy were made pre-operatively by ultrasound to enable prediction of rotator cuff repairability. Tears were classified following ultrasound as repairable or irreparable, and were correlated with intra-operative repairability. Results Ultrasound assessment of rotator cuff tear repairability has a sensitivity of 86% (p tear size (p tear size ≥4 cm2 or anteroposterior tear length ≥25 mm indicated an irreparable rotator cuff tear. Conclusions Ultrasound assessment is accurate in predicting rotator cuff tear repairability. Tear size or anteroposterior tear length and age were the best predictors of repairability. PMID:27582996

The study included 24 patients where the diagnoses of popliteal injuries were prospectively made based on MR appearances. The study group was taken from 2412 consecutive knee MRIs. The injuries were characterized as to involving the muscular or tendinous portions of the popliteus apparatus. In 95.8% (23/24) of patients, the tears of the popliteus involved the muscular portion. The injuries were either partial and interstitial or complete. Three patients had tears of both the muscular and tendinous portions or the tendon alone. The anterior and posterior cruciate ligaments were torn in 16.7% (4/24) and 29.2% (7/24) of patients, respectively. There were medial and lateral meniscal tears in 45.8% (11/24) and 25% (6/24) of patients, respectively. There were injuries of the medial and lateral collateral ligaments in 8.3% (2/24) and 4.2% (1/24) of patients, respectively. Bone bruises and/or fractures were seen in 33.3% (8/24) patients. In 8.3% (2/24) of patients, the popliteus injury was an isolated finding. (orig./MG)

Full Text Available Based on the analysis on temperature and stress distributions, as well as fatigue crack propagation in cutting tools, a model for designing compositional distribution and microstructure with graded characteristics was proposed. The addition of ductile phase and the introduction of the graded structure are beneficial to slow down the fatigue crack propagation rate and improve tool life.Al2O3-(W,TiC-TiN-Mo-Ni nano-composite tool material with graded structures was fabricated via two stage hot pressing sintering process, and the microstructure and mechanical properties were studied. The results show that the surface hardness, fracture toughness of inner layer and bending strength of the cermet with sintered gradient structure reach 19.258GPa, 10.015MPa·m1/2 and 1017.475MPa,respectively.The performance requirements to cutting tools were met. The dimple cleavage and torn edge of the binding phase in the fracture surfaces can be beneficial to the improvement of the fracture toughness and bending strength,so the resistance to fatigue crack propagation of tools is improved.

The Case of Abel: Religion as Boon and Bane for a Catholic Gay Man.

Science.gov (United States)

Cerbone, Armand R; Danzer, Graham

2017-08-01

Conservative religions that condemn homosexual sexual orientation and acts as unnatural and sinful pose significant challenges for gay persons whose faith is a core part of their identity. The condemnation presents a serious barrier to the acceptance and integration of their sexuality, a primary task of psychosexual development. As a result, they can manifest depression, anxiety, suicidal ideation, and even suicide attempts. The ecclesiastical censure also imposes an untenable dilemma for homosexuals in that they feel pressed to reject their sexual identity or renounce their spiritual identity and heritage. Psychotherapists who treat gay persons caught in this quandary can find themselves facing a similar problem: how to help their homosexual client reconcile their proscribed sexuality with their spiritual commitments. The case presented here recounts the treatment over many years of a gay man suffering from such a conflict and his eventual accommodation of both his homosexuality and his faith. Recommendations are offered for constructive treatment with those torn between two conflicting core identities. © 2017 Wiley Periodicals, Inc.

2011-01-01

Background This study compared the results of patients treated for ulnar impaction syndrome using an ulnar shortening osteotomy (USO) alone with those treated with combined arthroscopic debridement and USO. Methods The results of 27 wrists were reviewed retrospectively. They were divided into three groups: group A (USO alone, 10 cases), group B (combined arthroscopic debridement and USO, 9 cases), and group C (arthroscopic triangular fibrocartilage complex [TFCC] debridement alone, 8 cases). The wrist function was evaluated using the modified Mayo wrist score, disabilities of the arm, shoulder and hand (DASH) score and Chun and Palmer grading system. Results The modified Mayo wrist score in groups A, B, and C was 74.5 ± 8.9, 73.9 ± 11.6, and 61.3 ± 10.2, respectively (p 0.05). Conclusions Both USO alone and combined arthroscopic TFCC debridement with USO improved the wrist function and reduced the level of pain in the patients treated for ulnar impaction syndrome. USO alone may be the preferred method of treatment in patients if the torn flap of TFCC is not unstable. PMID:21909465

How much Takfir is too much Takfir? The Evolution of Boko Haram’s Factionalization

Jacob Zenn

2017-06-01

Full Text Available This article explores the ways in which the doctrine of takfir has been a central component in causing the Boko Haram movement to factionalize. The paper considers the historical origins of the concept of takfir and then turns to looking at how this concept has been (reinterpreted in the contemporary period among jihadist groups such as Boko Haram. Contemporary usage of takfirism as an ideology has often led to lethal consequences for civilians on the ground who are labeled “Kafir”, and devastating consequences for the internal cohesion of groups who use takfir as disagreements arise over who is or is not “Kafir”. The concept is highly controversial, and has torn jihadist movements apart. The priority given to this concept in Boko Haram factions provides an illustrative case study of takfirism in contemporary jihadist movements. In the conclusion, the article provides recommendations on how this concept can be incorporated into CVE programs and especially de-radicalization of both leaders and foot soldiers of Boko Haram.

The objective of this study was to delineate the moving anterior cruciate ligament (ACL) with multiple rapid magnetic resonance (MR) imaging. Rapid gradient echo MR images with an one-shot acquisition time of a half-second were accomplished by short repetition time and phase encoding reduction. Using a mobile knee brace and a flexible surface coil, half-second acquisitions were sequentially acquired during active, constant knee movement. Sixteen knees with intact ACLs and 27 knees with arthroscopically proven ACL tears were examined. Normal ACLs were identified as moving linear low-intensities. The ligaments were readily identified as straight or minimally curved structures when the knee was in semi-flexion compared to the knee extension. Torn ACLs were demonstrated as moving fragments or an amorphous configuration. Intermittent appearances of joint fluid interrupted the ligamentous continuities. Compared to the static images, no significant superiority of the kinematic imaging was found in diagnosis of ACL tears. However, this instant kinematic imaging is feasible with a standard MR system and can provide morphological information for functional analysis of the knee. (author)

2006-01-01

An anatomical study was carried out to evaluate the safety of the liver hanging maneuver for the right hemiliver in living donor and in situ splitting transplantation. During this procedure a 4-6 cm blind dissection is performed between the inferior vena cava and the liver. Short subhepatic veins entering the inferior vena cava from segments 1 and 9 could be torn with consequent hemorrhage. One hundred corrosive casts of livers were evaluated to establish the position and diameter of short subhepatic veins and the inferior right hepatic vein. The average distance from the right border of the inferior vena cava to the opening of segment 1 veins was 16.7+/-3.4 mm and to the entrance of segment 9 veins was 5.0+/-0.5 mm. The width of the narrowest point on the route of blind dissection was determined, with the average value being 8.7+/-2.3 mm (range 2-15 mm). The results show that the liver hanging maneuver is a safe procedure. A proposed route of dissection minimizes the risk of disrupting short subhepatic veins (7%).

In this manuscript, a Lebanese trainee psychiatrist qualitatively analyses and discusses the provision of mental healthcare services for Palestinian refugees in Lebanon. There are more than 250,000 Palestinian people sporadically dispersed in the refugee camps in Sidon, Beirut and other major cities in the Levant. Displacement, conflict, trauma, unemployment and poverty are but some of the myriad factors that influence Palestinian refugee mental health. This article traces the historical, political and socioeconomic determinants of health for Palestinians exiled in Lebanon and describes the pivotal role that the non-Govenmental Organisation Medical Aid for Palestinians is playing in helping to alleviate the psychiatric distress of Palestinian sufferers of mental illness. The latter half of the manuscript contains an interview with a consultant psychiatrist about his experiences volunteering in the war-torn lands of Libya post Arab Spring. He expounds on how he feels mental healthcare services in Libya are woefully inadequate and broaches on his perception of how the resilience and the 'family-centric' model of the Libyan people has conferred a certain degree of protection towards developing severe psychiatric illness.

Meniscal injuries are common in young physically active individuals, particularly those who are involved in contact level 1 sports that involve frequent pivoting, such as soccer and American football. This is a unique population because of their high physical activity at a young age, and it is important that correct diagnosis and appropriate treatment are provided, as the medial and lateral menisci are essential for normal knee function. In this article, we review the anatomy and function of the meniscus, the epidemiology of meniscal tears, and mechanism(s) of injury. Important concomitant injuries are also discussed. When making a diagnosis, relevant patient history, physical examination, and appropriate imaging studies are required. Nonoperative treatment is rarely successful for treating meniscal tears in young athletes, and therefore repair of the torn menisci is often required. We also discuss partial resection (which should only be performed when repair is not possible), as well as rehabilitation protocols after repair has been performed. All of these factors associated with meniscal injuries are important for a physician when diagnosing and treating these often complex injuries.

Contact sport and osteoarthritis.

Osteoarthritis (OA) is the most common joint disease in the world and the single largest cause of disability for those over 18 years. It affects more than twice as many people as does cardiac disease, and increases in incidence and prevalence with age. Animal and human studies have shown no evidence of increased risk of hip or knee OA with moderate exercise and in the absence of traumatic injury, sporting activity has a protective effect. One age-matched case control study found recreational runners who ran 12-14 miles per week for up to 40 years had no increase in radiological or symptomatic hip or knee OA. However, higher rates of hip OA occur in contact sports than in age-matched controls, with the highest rate in professional players. Soccer players with torn anterior cruciate ligaments (ACL) are more likely to develop knee OA than those with intact ACL. Early ACL repair reduces the risk of knee OA, but does not prevent it. Established injury prevention programmes have been refined to prevent injuries such as ACL rupture.

The biopsychosocial model and its potential for a new theory of homeopathy.

Since the nineteenth century the theory of conventional medicine has been developed in close alignment with the mechanistic paradigm of natural sciences. Only in the twentieth century occasional attempts were made to (re)introduce the 'subject' into medical theory, as by Thure von Uexküll (1908-2004) who elaborated the so-called biopsychosocial model of the human being, trying to understand the patient as a unit of organic, mental, and social dimensions of life. Although widely neglected by conventional medicine, it is one of the most coherent, significant, and up-to-date models of medicine at present. Being torn between strict adherence to Hahnemann's original conceptualization and alienation caused by contemporary scientific criticism, homeopathy today still lacks a generally accepted, consistent, and definitive theory which would explain in scientific terms its strength, peculiarity, and principles without relapsing into biomedical reductionism. The biopsychosocial model of the human being implies great potential for a new theory of homeopathy, as may be demonstrated with some typical examples. Copyright © 2012. Published by Elsevier Ltd.

Full Text Available Investigam-se formas de integração entre atividades computacionais e experimentais de modo a torná-las complementares, auxiliando os alunos a atingirem uma aprendizagem significativa de conceitos de Física e compreenderem algumas ideias sobre modelos científicos. A proposta didática, fundamentada: na teoria de Ausubel sobre aprendizagem significativa, na visão epistemológica de Bunge sobre modelos teóricos, e na teoria sociointeracionista de Vygotsky, foi aplicada a uma turma de licenciatura em Física da UFRGS, abrangendo todo o conteúdo de Eletromagnetismo em nível de Física Geral. Os resultados mostram que a integração proposta pode proporcionar aos alunos uma visão epistemológica mais adequada sobre o papel dos modelos teóricos em Física e das atividades computacionais e experimentais nos processos de aprendizagem, promovendo a interatividade e seu engajamento no próprio aprendizado, e transformando a sala de aula em um ambiente propício para uma aprendizagem significativa.

“Seeing the Life”: Redefining self-worth and family roles among Iraqi refugee families resettled in the United States

Social and geographic displacement is a global phenomenon that precipitates novel stressors and disruptions that intersect with longstanding familial and social roles. Among the displaced are war-torn Iraqi refugee families, who must address these new obstacles in unconventional ways. This study explores how such disruptions have influenced associations between gender and apparent self-worth experienced by Iraqi refugee families upon relocation to the United States. Further, the psychosocial mechanisms requisite of any novel approach to a new social construct are explored and reveal that production in the family is at the core of instability and shifting power dynamics during resettlement, preventing family members from “seeing the life” in the United States that they had envisioned prior to immigration. Over 200 semi-structured qualitative interviews with Iraqi participants and mental health providers were conducted over the course of the study, and demonstrate a plasticity among social roles in the family and community that transcends the notion of a simple role reversal, and illustrate the complex positionalities that families under stress must approximate during such physical and social displacement.

Full Text Available As reformas educacionais ocorridas na década de 1990 objetivaram intervir na formação dos trabalhadores para torná-los aptos às demandas da mundialização do capital. Na área da Educação Física, as novas diretrizes curriculares são o resultado dessas reformas, assumindo o papel de mediar as relações entre a formação e a intervenção do professor. Este artigo, extrato de uma pesquisa bibliográfica e documental fundada no Materialismo Histórico-Dialético, analisou o processo de elaboração das Diretrizes Curriculares Nacionais para os cursos de graduação em Educação Física. Assinala-se que esses documentos legais, além de legitimar os interesses da classe social ideologicamente identificada com o capital, tendem a subsumir a formação do trabalhador em Educação Física a essa lógica.
