Historically, a heterogeneous group of acute and chronic diseases, including rheumatoid arthritis, systemic lupus erythematosus, progressive systemic sclerosis, dermatomyositis, etc. This classification was based on the notion that "collagen" was equivalent to "connective tissue", but with the present recognition of the different types of collagen and the aggregates derived from them as distinct entities, the term "collagen diseases" now pertains exclusively to those inherited conditions in which the primary defect is at the gene level and affects collagen biosynthesis, post-translational modification, or extracellular processing directly.

Diseases characterized by inflammation involving multiple muscles. This may occur as an acute or chronic condition associated with medication toxicity (DRUG TOXICITY); CONNECTIVE TISSUE DISEASES; infections; malignant NEOPLASMS; and other disorders. The term polymyositis is frequently used to refer to a specific clinical entity characterized by subacute or slowly progressing symmetrical weakness primarily affecting the proximal limb and trunk muscles. The illness may occur at any age, but is most frequent in the fourth to sixth decade of life. Weakness of pharyngeal and laryngeal muscles, interstitial lung disease, and inflammation of the myocardium may also occur. Muscle biopsy reveals widespread destruction of segments of muscle fibers and an inflammatory cellular response. (Adams et al., Principles of Neurology, 6th ed, pp1404-9)

Transcatheter closure of a mid-muscular ventricular septal defect with an amplatzer VSD occluder device. (1/75)

A 5 year old girl with a haemodynamically significant mid-muscular ventricular septal defect (VSD) had successful transcatheter closure using the Amplatzer VSD occluder. This device passes through a small diameter sheath and can be easily retrieved or repositioned. These properties may make it a suitable device for closure of large mid-muscular defects in small children.  (+info)

Should initial clamping for abdominal aortic aneurysm repair be proximal or distal to minimise embolisation? (2/75)

OBJECTIVES: to determine whether clamping proximally or distally on the infrarenal aorta during abdominal aortic aneurysm (AAA) repair increases the overall embolic potential. MATERIALS AND METHODS: a sheath was placed in the mid-infrarenal aorta of 16 dogs. In eight animals a cross-clamp was placed at the aortic trifurcation, and in another eight animals it was placed in the immediate subrenal position. Under fluoroscopy blood flow within the infrarenal aorta was evaluated by contrast and particle injections. Grey-scale analysis was used to calculate contrast density. Particle distribution was followed fluoroscopically and confirmed pathologically. RESULTS: fifty-seven+/-24% of injected contrast remained within the aorta with distal clamping while 97+/-7% did so with proximal clamping (p<0.01). With distal aortic clamping 6.2+/-1. 3 out of 10 injected particles remained within the aorta after 15 seconds and only 0.8+/-0.8 remained after 5 min. With proximal aortic clamping, all 10 of the particles remained within the aortic lumen for the full 5 minutes (p<0.001). CONCLUSIONS: initial distal clamping minimises distal embolisation, but may result in renal and/or visceral embolisation. Initial proximal clamping prevents proximal embolisation and does not promote distal embolisation. We recommend initial proximal clamping in aortic aneurysm surgery to minimise the overall risk of embolisation.  (+info)

A CT method to measure hemodynamics in brain tumors: validation and application of cerebral blood flow maps. (3/75)

BACKGROUND AND PURPOSE: CT is an imaging technique that is routinely used for evaluating brain tumors. Nonetheless, imaging often cannot show the distinction between radiation necrosis and neoplastic growth among patients with recurrent symptoms after radiation therapy. In such cases, a diagnostic tool that provides perfusion measurements with high anatomic detail would show the separation between necrotic areas, which are characterized by low perfusion, from neoplastic areas, which are characterized by elevated CBF. We attempted to validate a dynamic contrast-enhanced CT method for the measurement of regional CBF in brain tumors, and to apply this method by creating CBF maps. METHODS: We studied nine New Zealand White rabbits with implanted brain tumors. We obtained dynamic CT measurements of CBF, cerebral blood volume (CBV), and permeability surface (PS) from the tumor, peritumor, and contralateral normal tissue regions. In all nine rabbits (two studies per rabbit), we compared CT-derived CBF values with those simultaneously obtained by the standard of reference ex vivo microsphere technique. Using CT, we examined three rabbits to assess the variability of repeated CBF and CBV measurements; we examined the other six to evaluate regional CBF reactivity to arterial carbon dioxide tensions. Finally, CT CBF maps were obtained from a rabbit with a brain tumor during normocapnia and hypocapnia. RESULTS: We found a significant linear correlation (r = 0.847) between the regional CT-and microsphere-derived CBF values, with a slope not significantly different from unity (0.99+/-0.03, P>.01). The mean difference between regional CBF measurements obtained using both methods did not significantly deviate from zero (P>.10). During normocapnia, tumor had significantly higher CBF, CBV, and PS values (P<.05) than did peritumor and normal tissues. The variability in CT-derived CBF and CBV measurements in the repeated studies was 13% and 7%, respectively. CT revealed no significantly different CBF CO2 reactivity from that determined by the microsphere method (P>.10). The CBF map of tumor regions during normocapnia showed much higher flow than normal regions manifested, and this difference was reduced on the hypocapnia CBF map. CONCLUSION: The dynamic CT method presented herein provides absolute CBF measurements in brain tumors that are accurate and precise. Preliminary CBF maps derived with this method demonstrate their potential for depicting areas of different blood flow within tumors and surrounding tissue, indicating its possible use in the clinical setting.  (+info)

Papillary muscle shortening in the intact dog; a cinderadiographic study of tranquilized dogs in the upright position. (4/75)

Shortening of the anterior papillary muscle of the left ventricle was demonstrated in six intact, tranquilized dogs. Two small metal markers that had been surgically implanted 3-50 months earlier were cineradiographically photographed during approximately ten sequential cardiac cycles in each of two orthogonal positions. Distances between markers were plotted for successive frames. The resulting curves were used to obtain maximum velocities of papillary muscle shortening and lengthening: 1.08 plus or minus 0.29 muscle lengths/sec and 1.39 plus or minus 0.48 muscle lengths/sec, respectively. From the two orthogonal planes, the average maximum spatial distance and the average minimum spatial distance between the markers were calculated. The mean percent shortening of 22.8 plus or minus 6.5% was surprisingly large: it approximated the distance from the foot to the peak of the ascending limb of the myocardial length-tension curve derived from isolated muscle studies. Mechanical studies on isolated papillary muscle have consistently shown reduced shortening with increasing loads. Since the in vivo dog papillary muscle has been reported to be under considerable tension during systole, there appears to be some contradiction between the degree of shortening found in the present study and the shortening observed in isolated papillary muscle studies.  (+info)

Cricopharyngeal myotomy: treatment of dysphagia. (5/75)

Six patients are presented who underwent cricopharyngeus myotomy for dysphagia. The clinical history and cine studies appear to be the most useful assessments in defining patients with dysphagia who may improve after a myotomy. Etiological factors which may precipitate poor coordination of the swallowing mechanism and a relative cricopharyngeus muscle obstruction include neuromuscular disorders, radical oral surgery, central nervous disease, and idiopathic disorders, although the exact physiology of the cricopharyngeus muscle in health and disease is not as yet delineated, the muscle is being implicated in many problems as the inciting factor of upper esophageal dysphagia. The operation of cricopharyngeus myotomy is a relatively simple procedure and should be done with little morbidity and mortality in properly selected cases.  (+info)

Basic limb kinematics of small therian mammals. (6/75)

A comparative study of quantitative kinematic data of fore- and hindlimb movements of eight different mammalian species leads to the recognition of basic principles in the locomotion of small therians. The description of kinematics comprises fore- and hindlimb movements as well as sagittal spine movements including displacement patterns of limb segments, their contribution to step length, and joint movements. The comparison of the contributions of different segments to step length clearly shows the proximal parts (scapula, femur) to produce more than half of the propulsive movement of the whole limb at symmetrical gaits. Basically, a three-segmented limb with zigzag configuration of segments is mainly displaced at the scapular pivot or hip joint, both of which have the same vertical distance to the ground. Two segments operate in matched motion during retraction of the limb. While kinematic parameters of forelimbs are independent of speed and gait (with the scapula as the dominant element), fundamental changes occur in hindlimb kinematics with the change from symmetrical to in-phase gaits. Forward motion of the hindlimbs is now mainly due to sagittal lumbar spine movements contributing to half of the step length. Kinematics of small therian mammals are independent of their systematic position, their natural habitat, and also of specific anatomical dispositions (e.g. reduction of fingers, toes, or clavicle). In contrast, the possession of a tail influences 'pelvic movements'.  (+info)

Torque patterns of the limbs of small therian mammals during locomotion on flat ground. (7/75)

In three species of small therian mammals (Scandentia: Tupaia glis, Rodentia: Galea musteloides and Lagomorpha: Ochotona rufescens) the net joint forces and torques acting during stance phase in the four kinematically relevant joints of the forelimbs (scapular pivot, shoulder joint, elbow joint, wrist joint) and the hindlimbs (hip joint, knee joint, ankle joint, intratarsal joint) were determined by inverse dynamic analysis. Kinematics were measured by cineradiography (150 frames s(-1)). Synchronously ground reaction forces were acquired by forceplates. Morphometry of the extremities was performed by a scanning method using structured illumination. The vector sum of ground reaction forces and weight accounts for most of the joint force vector. Inertial effects can be neglected since errors of net joint forces amount at most to 10 %. The general time course of joint torques is comparable for all species in all joints of the forelimb and in the ankle joint. Torques in the intratarsal joints differ between tailed and tail-less species. The torque patterns in the knee and hip joint are unique to each species. For the first time torque patterns are described completely for the forelimb including the scapula as the dominant propulsive segment. The results are compared with the few torque data available for various joints of cats (Felis catus), dogs (Canis lupus f. familiaris), goats (Capra sp.) and horses (Equus przewalskii f. caballus).  (+info)

Clinical significance of coronary calcification. (8/75)

Coronary artery calcification (CAC) was assessed by cinefluoroscopy and its extent was scored (CAC score) in 2,163 consecutive patients undergoing coronary angiography, based on the angiographic and clinical data, the patients were categorized into 8 types of coronary artery disease (CAD). The CAC score was lowest in angiographically normal subjects (0.12+/-0.60) and highest in patients with silent myocardial ischemia (14.31+/-8.61). Risk factors for CAC were advanced age, male sex (at age <80 years), hypertension, diabetes mellitus, and a high grade of organic coronary stenosis. The CAC score in patients with acute coronary syndrome (unstable angina+acute myocardial infarction; 5.48+/-7.42) was significantly lower than that in those with chronic CAD (silent ischemia+stable angina; 9.72+/-8.73; p<0.0001), but was still higher than that in normal subjects or those with vasospastic angina (0.92+/-2.88; p<0.0001). The results indicate that CAC is a manifestation of coronary atherosclerosis and its appearance depends on the pathological type of ischemic heart disease. Fixed stenosis with a slow and chronic process tends to be associated with CAC. The clinical implication of extensive CAC in acute coronary syndrome compared with normal subjects should be further investigated.  (+info)

N2 - The aim of this study was to examine the difference in the myocardial volume between end-diastole and end-systole in 24 human volunteers, using steady-state free precession gradient-echo cine imaging of both long- and short-axis views of the left ventricle and a newly developed three-dimensional (3D) analysis method. In addition, we examined retrospectively the cine magnetic resonance imaging (MRI) studies from 20 of the subjects that included a stack of short-axis views, from base to apex, suitable for a standard two-dimensional (2D) analysis. With the 3D analysis method, no significant variance in the myocardial volume was found (mean difference=0.1%±9.1%, p=0.88) between end-diastole (ED) and end-systole (ES), while the 2D technique yielded significantly larger values for the LV ...
Many names exist in the medical literature for moving pictures taken with X-rays. They include fluoroscopy, fluorography, cinefluorography, photofluorography, fluororadiography, kymography (electrokymography, roentgenkymography), cineradiography (cine), videofluorography, and videofluoroscopy. Today the word fluoroscopy is widely understood to be a hypernym of all the aforementioned terms, which explains why it is the most commonly used and why the others are declining in usage.[33] The profusion of names is an idiomatic artifact of technological change, as follows: As soon as X-rays (and their application of seeing inside the body) were discovered in the 1890s, both looking and recording were pursued. Both live moving images and recorded still images were available from the very beginning with simple equipment; thus, both looking with a fluorescent screen (fluoro- + -scopy) and recording/engraving with radiation (radio- + -graphy) were immediately named with New Latin words-both words are ...
Did you know that the northern leopard frog uses its eyes to help with swallowing food? Its true!. The frog, also known as Rana pipiens, retracts its eyes and uses them to help push food down its throat.. According to The Journal of Experimental Biology:. Eye retraction can occur bilaterally or unilaterally, and both swallowing movements and eye retraction can occur separately as well as together. During swallowing, cineradiography shows that the eyes and associated musculature retract well into the oropharynx and appear to make contact with the prey item. This contact appears to help push the prey toward the esophagus, and it may also serve to anchor the prey for tongue-based transport.. As you can see, theres more to this frogs eating habits than meets the eye….unless youre a northern leopard frog!. Want to learn more about frogs?

Frog locomotion has attracted wide scientific interest because of the unusual and derived morphology of the frog pelvic girdle and hind limb. Previous authors have suggested that the design of the frog locomotor system evolved towards a specialized jumping morphology early in the radiation of the group. However, data on locomotion in frogs are biased towards a few groups and most of the ecological and functional diversity remains unexplored. Here, we examine the kinematics of swimming in eight species of frog with different ecologies. We use cineradiography to quantify movements of skeletal elements from the entire appendicular skeleton. Our results show that species with different ecologies do differ in the kinematics of swimming, with the speed of limb extension and especially the kinematics of the midfoot being different. Our results moreover suggest that this is not a phylogenetic effect because species from different clades with similar ecologies converge on the same swimming kinematics. We ...

A variation in the total transsection area of walls in a single radial row of tracheids as well as the dependence of the transsection area of walls of single tracheids on the cambial age of growth rings and on the tree growth rate in a 52-year even-aged pine stand were determined. The total area of transsection walls of tracheids ranges from 77⋅103 µm2 in the outer rings of the stem. This value changes with the cambial age of the growth ring according to a negative exponential curve. Due to the worsening of the conditions of tree growth in a stand, the total area of transsection of walls in a single row of tracheids for a given growth ring increases. There is a linear dependence between the total area of transsection of walls in a single row of tracheids and the number of tracheids in the growth ring. The mean area of transsection of walls of a single tracheid is constant within ±10%, irrespective of the type of tracheid (early or late), of the tree growth class, and of the zone of the stem ...
INTRODUCTION: Myocardial contraction fraction (MCF) is the ratio of left ventricular (LV) stroke volume to myocardial volume and may serve as a measure of appropriateness of LV mass. We sought to determine whether depressed MCF predicts major adverse cardiovascular events (MACE) in healthy adults.. METHODS: 318 Framingham Heart Study (FHS) Offspring cohort members (60±9 yrs, 158 men) underwent cardiovascular magnetic resonance (CMR) imaging in 1998-1999. Subjects were free of clinical cardiovascular disease and were recruited from equal strata of age, sex and quintile of Framingham Coronary Risk Score (FCRS), with double sampling of the top quintile. LV and myocardial volumes were determined from volumetric breathold-cine SSFP CMR datasets. MACE were: CV death, myocardial infarction (MI), stroke or new heart failure (HF). A Cox proportional hazards model adjusting for FCRS was used to estimate hazard ratio (HR) for MACE in the lowest within-sex quartile (Q1) of MCF vs. other quartiles (Q2- 4). ...

This report contrasts the diagnostic precision of cardiac catheterization technics with selective cinefluorography in 37 consecutive patients with suspected congenital heart disease and demonstrates the increased diagnostic precision gained by combining the technics in the individual patient.. The complete diagnosis was correctly determined preoperatively by combined study in 13 of the 14 patients operated upon. Neither technic completely diagnosed a cor triatiorium with anomalous pulmonary venous drainage. Of these 13 patients the precise diagnosis could be established solely by catheterization in 11 and solely by cinefluorography in eight. Catheterization studies failed to distinguish a coronary A-V fistula from other causes ...
Background-The impact of abdominal arterial calcific deposits on the prediction of cardiovascular disease (CVD) over a long follow-up interval deserves greater scrutiny.. Methods and Results-Lateral lumbar radiographs were studied as a predictor of incident coronary heart disease (CHD), CVD, and CVD mortality in 1049 men and 1466 women (mean age, 61 years) who were followed from 1967 to 1989. Anterior and posterior wall calcific deposits in the aorta at the level of the first through fourth lumbar vertebrae were graded according to increasing severity using a previously validated rating scale for abdominal aortic calcium (AAC) that ranges from 0 to 24 points. There were 454 cases of CHD, 709 cases of CVD, and 365 CVD deaths. Proportional hazards logistic regression was used to test for associations between AAC and later events after adjustment for age, cigarette use, diabetes mellitus, systolic blood pressure, left ventricular hypertrophy, body mass index, cholesterol, and HDL cholesterol.

These data were compared with the change in the volume of the same region of myocardium estimated from the change in angiographic opacification of the heart wall. Five dogs were anesthetized, and four pairs of 2-mm-diameter lead beads were attached to the epicardial and endocardial regions. Two scans using the dynamic spatial reconstructor (a high-speed computed tomographic scanner) were performed during aortograms, one under control conditions and the other during adenosine infusion. The results have shown that the increases of myocardial volume defined by the beads (ΔV(bead), % of volume at control) ...

The symposium is an outgrowth of these monthly meetings, where we will learn more about the exciting research in vertebrate genomics that is being conducted outside of Cornell, through presentations from distinguished invited speakers, and within Cornell, through a poster session where graduate students and post-doctoral fellows of CVG labs can showcase their own research. The symposium is held alternating-years in July. ...
We present a noninvasive technique for high-speed measuring of eye retraction and eyelid position during blinking. The anterior chamber of the eye is illuminated by the slit lamp of a biomicroscope and eye dynamics during a blinking sequence are captured with a high-speed camera working at 500 frames per second. Digital image processing allows quantitative analysis of cornea and eyelid positions during the closing and opening phases of the blinking process. Our method allows simultaneous measuring of corneal retraction, duration of down and up phases, total blinking duration, and average and peak speeds of the eyelids in both phases, thus providing a complete analysis of the blinks transversal motions.. © 2010 Optical Society of America.

This experimental study first demonstrated feasibility of a novel echocardiographic parameter that represented regional deformation measured as change in an endocardial area. The parameter, which had significant correlations with both LS and CS components, showed greater changes in ACR compared with 1D strain.. Recently introduced 3D-STI is a robust technology for strain measurements and can provide regional 1D strain (6,7). In addition, the usefulness of 3D-STI in assessing regional wall displacement and strain, LV volume measurements, and LV dyssynchrony has been reported in clinical studies (8-10). In addition, the 3D-STI can track regional endocardial area and calculate changes in an area through the cardiac cycle, because of a 3D imaging system. The unique parameter, ACR, can be measured on the basis of the deformation of regional rectangular or trapezoidal area measured by orthogonal directional data, just as the present study has confirmed that area tracking had significant relations with ...

X-ray Talbot interferometry, which uses two transmission gratings, has the advantage that broad energy bandwidth x-rays can be used. We demonstrate the use of white synchrotron radiation for high-speed X-ray phase imaging and tomography in combination with an X-ray Talbot interferometer. The moiré fringe visibility over 20% was attained, enabling quantitative phase measurement. X-ray phase images with a frame rate of 500 f/s and an X-ray phase tomogram with a scan time of 0.5 s were obtained successfully. This result suggests a breakthrough for time-resolved three-dimensional observation of objects that weakly absorb X-rays, such as soft material and biological objects.. ©2009 Optical Society of America.

We investigated whether the quality of myocardial collagen associates with elevated left-sided filling pressures in 38 hypertensive patients with stage C chronic heart failure. Filling pressures were assessed invasively measuring pulmonary capillary wedge pressure. Left ventricular chamber stiffness constant was calculated from the deceleration time of the early mitral filling wave. The fraction of myocardial volume occupied by total collagen tissue and collagen type I fibers was assessed histomorphologically. The degree of collagen cross-linking (CCL), which determines the formation of insoluble stiff collagen, was assessed by colorimetric and enzymatic procedures. The expression of lysyl oxidase (LOX), which regulates CCL, was assessed by Western blot. Compared with patients with normal pulmonary capillary wedge pressure (≤12 mm Hg; n=16), patients with elevated pulmonary capillary wedge pressure (,12 mm Hg; n=22) exhibited increases of left ventricular chamber stiffness constant, fraction ...

Anesthesiology Research and Practice is a peer-reviewed, Open Access journal that provides a forum for health care professionals engaged in perioperative medicine, critical care, and pain management. The journal publishes original research articles, review articles, and clinical studies related to anesthetic administration, preoperative and postoperative considerations, perioperative care, critical care, pediatric anesthesia, obstetric anesthesia, analgesia, clinical and experimental research, administration and efficacy, as well as technology and monitoring.
1. In the anesthetized dog, end-diastolic, end-systolic and stroke volumes for the left ventricle have been calculated according to the method of Holt from dilution curves recorded at the aortic root. For heart rates of less than 120 beats per minute, the catheterdensitometer systems used gave 90 to 95 per cent of the true concentration in the aortic root at the end of diastole.. 2. Average volumes of 2.96, 1.63 and 1.33 ml./Kg. of body weight were calculated for each of these parameters. The interindividual and intraindividual variations about these means amounted to ± 30 to 50 per cent.. 3. In approximately 15 per cent of the dilution curves the concentration of dye in the aortic root during early systole (phase of maximal ejection) showed a transient, markedly low value compared with that of the end of diastole. This can be explained only on the basis of the preferential ejection from the heart in early systole of the undyed, newly entering blood from the left atrium, which had mixed poorly ...

The opposite pattern of VISI is seen in triquetrolunate dissociation. Because of the loss of ligamentous constraint the lunate comes under the now uncontested influence of the palmar- flexing scaphoid. Both scaphoid and lunate appear palmar flexed on PA radiographs, the scaphoid is foreshortened (ring sign) and the lunate is triangular in shape, coexisting with a dorsiflexed triquetrum in a low or distal position in relation to the lunate, leading to interruption of the proximal arc. This type of instability is more frequent in the rheumatoid wrist. Dynamic forms of carpal instability can only be recognised during cineradiographic studies.2 8 Patients with lesions of the triangular fibrocartilage complex complain of a painful click during wrist motions and tenderness is clearly localised to the dorsal anatomic depression, which is immediately distal to the ulnar head. Passive manipulation of the carpal condyle against the head of the ulna, with the wrist in ulnar deviation, will frequently ...
TY - JOUR. T1 - Successful coil embolization of pericardiacophrenic artery perforation occurring during transradial cardiac catheterization via right radial artery. AU - Arsanjani, Reza. AU - Echeverri, Jose. AU - Movahed, Mohammad Reza. PY - 2012/12/1. Y1 - 2012/12/1. N2 - The transradial approach for percutaneous coronary intervention (PCI) has gained increasing popularity as an alternative site for coronary angiography and intervention. The transradial approach has safely been used in patients with contraindications to the transfemoral approach. Despite its overall lower complication rates compared with the transfemoral approach, the transradial approach has its own inherent complications. The risk of arterial perforation with the transradial approach is less than 1%, primarily involving the radial artery with the incidence of compartment syndrome at approximately 0.004%. In addition, the risk of significant bleeding requiring transfusion with transradial approach is extremely rare, occurring ...
In order to study the pattern of clonal myocyte distribution during mammalian heart development, we have exploited embryo aggregation chimeras using, as cellular markers, an enhanced jellyfish green fluorescent protein (eGFP) transgene and a desmin-promoter-driven, nuclear-localized beta-galactosidase (nlacZ) knock-in. In neonatal, weanling, and adult chimeric atria and ventricles, irregularly formed patches of various sizes rather than highly dispersed cardiomyocytes were observed. Most of the smaller patches and single cardiomyocytes were found in spatial neighborhood of large patches. This indicated largely coherent clonal growth during myocardial histogenesis combined with tangential displacement or active migration of myocytes. The patterns of ventricular walls were simpler than those of the septum and the atria. In the adult heart, large myocardial volumes devoid of eGFP-positive cardiomyocytes indicated a lack of secondary immigration of blood-borne stem cells into the myocardium. The ...
Results Thirty patients were included, 20 female (66%), mean age 50 years (±11). On X-ray, calcifications were type A in 11 patients (36%) and type B in 19 patients (64%). Calcific deposits were mostly in the supraspinatus tendon (96%). Mean length, width and height of the calcific deposit were 15 mm (±6), 12 mm (±5.7) and 5.2 mm (±1.9) respectively. On US, calcification were arc shaped in 12 cases (40%), fragmented with shadowing in 15 (50%), without shadowing in one case and nodular in 2 cases (6.7%). Type A calcification on X-Ray were mainly arc shaped on US (80%) whereas type B on X-ray were fragmented or nodular on US in 79% of the cases. Bursitis was associated in 12 patients (40%). A significant correlation was found between the size of the calcification recorded on US and X-Ray (length (r=0.78), width (r=0.65) and height (r=0.59); p,0.01). A 3 months, 12 calcifications (40%) had completely disappeared on X-Ray, 3 (10%) were reduced between 50 and 90%, 9 (30%) reduced by less than 50% ...
Most patients spend a couple of hours in the recovery unit following a cardiac catheterization. If your procedure was done via the large artery in the groin, your doctor may have inserted a device or stitch to seal the hole that was made. If this is the case, he will lay flat for a couple of hours. If the tube was left in the groin and had to be pulled, he will lay flat for 4 hours or so following the procedure. You should not drive or lift heavy objects for a few days following the procedure. If your procedure was done via the small artery in the wrist, he or she will have a band over the artery in the wrist hold pressure on the artery. In the days following the procedure, you may feel some discomfort at the access site. There will also possibly be some bruising in the groin or over the wrist. If you feel a lump form, you should call your doctors office to let them know. If there is significant bleeding, you should hold pressure and call your doctors office or 911.. ...

In the beginning, there was awake blind nasal tracheal intubation, a brutal and often unsuccessful technique that thankfully disappeared when non-anesthesiologists gained access to paralytics. The primary tool for emergency airway management then became the traditional laryngoscope, a device little improved since the 1940s, until the advent of video laryngoscopy in the early 2000s which changed everything.. The age of VL was ushered in by the 2001 Glidescope, which simultaneously introduced two technologies: video (putting a camera at the end of the blade and projecting the image onto a screen), and hyperangulated geometry (blades with a much steeper curve that are designed not to move the tongue out of the way, but to advance around the tongue). It took us a decade to figure out that video was a transformational advance, but not hyperangulated geometry, which is a trade-off compared to conventional standard geometry (Macintosh or Miller) blades. But because they were introduced together, in the ...
Our results suggest that by using the Bayesian probabilistic method, reduced-contrast-dose brain DSC perfusion is feasible at 3T, with qualitative and quantitative results comparable with a full-dose control group. The Bayesian method outperformed the singular value decomposition (SVD)-deconvolution technique for reduced-contrast-dose DSC perfusion, in which the SNR was lower. Our data support the hypothesis that the inherent insensitivity of the Bayesian method to low SNR can provide acceptable measurement of cerebral perfusion in comparison with FD scans. This is reflected in a higher qualitative and quantitative correlation between HD and FD data in Bayesian-processed data in comparison with cSVD.. A fundamental issue in DSC processing is the conversion of the observed concentration time curve into reliable estimates of CBF, CBV, and MTT. Most processing techniques by using the indicator-dilution theory assume that the observed concentration time curve is the convolution of the arterial input ...

In almost all species, the shoulder, elbow and wrist joints display biphasic angular movements during one step cycle for both symmetrical gaits and in-phase gaits (except for the wrist in Procavia and the shoulder in Tupaia; Fig. 2A,B). Phase relationships between different joints indicate that extensions in the shoulder, elbow and wrist joints are not synchronised. Flexion of all joints starts before touch-down, causing retraction of the segments. Flexion in the elbow joint reaches its maximum at 10-20 % of step duration (20-40 % of stance duration) (Fig. 2A,B), when the hand passes underneath the shoulder joint. Shoulder extension starts at midstance. The maximal dorsiflexion of the hand is reached at 65-70 % of stance duration. The second flexion of the shoulder joint coincides with the beginning of scapula protraction at the end of the stance phase. The elbow flexion initiates protraction of the forearms while maximum plantarflexion of the wrist joint occurs only in the first half of swing ...

Traditional treatments for transsphincteric perirectal fistulae rely upon an immediate (fistulotomy) or delayed (seton) transsection of the sphincter muscle possibly resulting in fecal incontinence, take a long time to heal, and/or are associated with significant failure rates (ex. fibrin glue).. Newer treatment concepts such as the collagen plug do not physically interrupt the sphincter muscle, avoid and minimize the risk of fecal incontinence, and decrease the time to fistula healing. Exciting initial reports have confirmed the collagen plugs utility in treating perirectal fistulae, but a systematic scientific comparison is needed to validate the new, less invasive plug method.. The primary goal of this study is to show that the collagen plug heals transsphincteric perirectal fistulae as well as the conventional seton method. ...

Good morning. So we are going to talk about genetic susceptibility to GI cancers today. As Dr. Brand just said, the first part will be about colon syndromes and then hell talk to you a little bit about pancreatic syndromes as well. So this is interactive, Im going to give you guys some case scenarios and ask you to tell me what you think the genetic syndrome is. So please participate.. All right. So just a little bit of an overview for you first. This is information that you may already know but just if you are seeing a patient and thinking about whether or not they may have a hereditary predisposition to cancer these are the sorts of things that you would want to keep in mind. So young age of cancer diagnosis, typically before age 50; if there are multiple people that have either the same or genetically related types of cancer; people with more than one cancer diagnosis; people with unusual types of cancer; and then of course from a colon perspective people who have lots and lots of colon ...
