Evaluation of coronary arterial patterns in complete transposition by laid-back aortography

AbstractFor the visualization of the coronary arterial patterns in complete transposition (concordant atrioventricular and discordant ventriculoarterial connections), balloon occlusion aortography has been performed in right and left anterior oblique or in frontal and lateral views. These views, however, are often unsatisfactory because of super-imposition of the aortic sinuses. The so-called “laid-back” view is a newly developed angiographic projection in which the aortic sinuses and the intervening commissures are imaged as if they were seen from below and the front. We performed such laid-back aortography in 36 consecutive patients with an echocardiographic diagnosis of complete transposition. In 23 of 36 patients, we obtained additional aortograms in right and left anterior oblique views. For the evaluation of the diagnostic value of the laid-back view, as compared with that of the combined right and left anterior oblique views, both sets of aortograms were reviewed independently by the five reviewers who were asked to make a diagnosis and to specify their levels of confidence (“definite,” “probable,” and “possible”) for their diagnosis. Error rates were significantly lower for the laid-back aortograms than for the combined right and left aortograms (4 and 11%, respectively). An increased level of confidence was significantly associated with the laid-back aortograms. We illustrate the anatomy of various coronary arterial patterns seen by laid-back aortography.

As If

The grip reflex of the foot (Fusssohlengreifreflex) is described by me as a rudimentary human reflex found physiologically in newborns and infants. This reflex consists in the fact that, when the experimenter lightly puts the finger of the hand or another, preferably thin, round, long object (pencil, stick, etc.) to the sole of the infant, the latter quickly and intensively flexes the toes and the foot itself, as if he wanted to embrace with his foot the experimenter's finger, just as the same infant grasps firmly and tonically holds the finger enclosed in his palm.

Background:Early diagnosis of mild cognitive impairment is important in Alzheimer's disease management before brain damage is profoundly established and irreversible. Eye-tracking technology is a sensitive method to measure cognitive impairments in dementia and MCI. We examined the saccade movement deficits in amnestic MCI and compared them with the normal controls and Alzheimer to define early cognitive markers in MCI.Method:This study was a cross-sectional observational study. Twenty-one patients with AD, 40 patients with aMCI, and 59 normal participants were examined by eye tracking using anti-saccade task and pro-saccade task with ‘gap’ and ‘overlap’ procedures.Results:Patients with Alzheimer's made more errors, and corrected fewer errors than a-MCI and age-matched controls. Moreover, a-MCI had higher error rates in the prosaccade gap and overlap (38±1.5, p≤ 0.001; 21± 1.8, p≤ 0.001) and antisaccade gap and overlap (64± 1.4, p≤ 0.001; 45± 1.6, p≤ 0.001) than normal controls. Compared with the control group, a-MCI also showed more uncorrected responses in the prosaccade gap (6± 0.5, p≤ 0.001) and antisaccade gap and overlap (13± 0.4, p≤ 0.001; 10± 0.7, p≤ 0.001). Saccade Omission also revealed significant differences between normal controls and amnestic mild cognitive impairment in prosaccade (p≤ 0.001) and antisaccade (p≤ 0.001) tasks, in both gap and overlap paradigms.Conclusion:Error proportion, target omission and uncorrected saccades impairments in a- a-MCI, support the concept of executive function deterioration, as an early marker of neurocognitive disorder. Our findings also confirm inhibitory and working memory impairments t in a-MCI.

As If

Interlacing one’s fingers can cause misperception of finger positions. Observer’s (O’s) fingers were interlaced in six different ways and experimenter (E) tapped two adjacent fingers in quick succession (e.g., tapping the right middle finger then the left ring finger). O had to state the perceived direction in which the tapping occurred, and errors were recorded. When hands were well separated, touching two adjacent fingers of one hand gave error rates of only 2.4%, and touching a finger on one hand then the other gave error rates of only 3.4%. Interlacing the fingers as if in prayer increased error rates to 9%. When hands were superimposed with finger pointing away from O’s body, error rates rose further to 30%. Observers knew which fingers were which, but they were confused about exactly where their fingers were. Thus, somatotopic was greatly superior to spatiotopic localization.

Good Agreement

For years the separation of carcinoma and sarcoma and the subclassification of sarcomas has been based on the appearance of the tumor cells and their microscopic growth pattern and information derived from certain histochemical and special stains. Although this method of study has produced good agreement among pathologists in the separation of carcinoma from sarcoma, it has given less uniform results in the subclassification of sarcomas. There remain examples of neoplasms of different histogenesis, the classification of which is questionable because of similar cytologic and growth patterns at the light microscopic level; i.e. amelanotic melanoma versus carcinoma and occasionally sarcoma, sarcomas with an epithelial pattern of growth simulating carcinoma, histologically similar mesenchymal tumors of different histogenesis (histiocytoma versus rhabdomyosarcoma, lytic osteogenic sarcoma versus rhabdomyosarcoma), and myxomatous mesenchymal tumors of diverse histogenesis (myxoid rhabdo and liposarcomas, cardiac myxoma, myxoid neurofibroma, etc.)

As If

We recently described an artificial substrate system which could be used to optimize labeling parameters in EM immunocytochemistry (ICC). The system utilizes blocks of glutaraldehyde polymerized bovine serum albumin (BSA) into which an antigen is incorporated by a soaking procedure. The resulting antigen impregnated blocks can then be fixed and embedded as if they are pieces of tissue and the effects of fixation, embedding and other parameters on the ability of incorporated antigen to be immunocyto-chemically labeled can then be assessed. In developing this system further, we discovered that the BSA substrate can also be dried and then sectioned for immunolabeling with or without prior chemical fixation and without exposing the antigen to embedding reagents. The effects of fixation and embedding protocols can thus be evaluated separately.

Purpose This retrospective analysis examined group differences in error rate across 4 contextual variables (clusters vs. singletons, syllable position, number of syllables, and articulatory phonetic features) in adults with apraxia of speech (AOS) and adults with aphasia only. Group differences in the distribution of error type across contextual variables were also examined. Method Ten individuals with acquired AOS and aphasia and 11 individuals with aphasia participated in this study. In the context of a 2-group experimental design, the influence of 4 contextual variables on error rate and error type distribution was examined via repetition of 29 multisyllabic words. Error rates were analyzed using Bayesian methods, whereas distribution of error type was examined via descriptive statistics. Results There were 4 findings of robust differences between the 2 groups. These differences were found for syllable position, number of syllables, manner of articulation, and voicing. Group differences were less robust for clusters versus singletons and place of articulation. Results of error type distribution show a high proportion of distortion and substitution errors in speakers with AOS and a high proportion of substitution and omission errors in speakers with aphasia. Conclusion Findings add to the continued effort to improve the understanding and assessment of AOS and aphasia. Several contextual variables more consistently influenced breakdown in participants with AOS compared to participants with aphasia and should be considered during the diagnostic process.
