We consider a typical master equation describing thermal time-evolution. In parallel, we also consider a quasi static canonical description of the same problem. We are able to devise a way of numerically comparing these two treatments and concoct a distance-measure between them. In this way, one is in a position to know how far or close equilibrium and off-equilibrium can get. The first, rather surprising observation, is that our systems lose structural details as N grows. Also, the time-evolution of the distance between the two pertinent probability distributions is quite sensitive to the heating-cooling process.

The goal of this research was to develop a digital system that could allow managing electronic medical records (EMRs) codified under specifications of the Health Level 7/Clinical Document Architecture (HL7/CDA) international standard, and saving them in a portable digital storage device called iButton?. To this end, an USB-based hardware interface for reading and storing EMRs in iButtons was designed and implemented. In addition, a software application for invoking read/write operations on stored EMRs and showing their content on a graphical user interface was also developed, following the Extreme Programming (XP) software development methodology and using Visual Basic .NET as programming language. Tests conducted on the hardware interface showed that it was able to recognize any iButton type, reading and writing data on them as well. Moreover, the system helped in creating empty EMRs in conformance with the HL7/CDA standard, adding and viewing information, and updating it in the iButton. This system offers an easy way for managing and visualizing medical records codified in HL7/CDA, and allows patients to take their updated medical history with them everywhere.

Purpose: To report two quite rare cases of giant schwannomas of the cervical and thoracic spine. Surgical resection is usually the treatment of choice for these neoplasms. Methods: The first patient is a 48-year-old male that came to our department, complaining about weakness and paresthesia of both lower extremities and upper left extremity, and a considerably big dorsal palpable lump. MRI and CT scan were used to diagnose giant cervical schwannoma. Because of the intensity of symptoms, he was subjected to surgery. Multidisciplinary resection involving neurosurgical and oncosurgicalteamn was performed for intravertebral and extravertebral approaches. The second patient is a 55-year-old female that came to the hospital complaining about incapacitating pain and dysesthesia involving T6, T7, and T8 dermatomes, with no other deficits. MRI and CT scan were used to diagnose giant thoracic schwannoma. Because of the intensity of the pain, surgery was decided as the treatment of choice. Video assisted thoracoscopic surgery was performed and total resection was achieved, with improvement of the symptoms. Results: Both patients showed complete remission of the symptoms, with no major deficits after surgery. Conclusion: Although infrequent, giant spinal schwannomas may be the cause of visible lumps in the back with radicular symptoms. When asymptomatic, conservative treatment could be viable, but when they present symptoms, surgery offers good results.

Introduction: To perform a Latin-American multicentric study for the prediction of benign and malignant thyroid nodules using Alpha Score, and to compare it with ACR TIRADS® and Bethesda®. Materials and Methods: A prospective multicentric study in 10 radiological hospitals and institutions of Latin America was performed and 818 thyroid nodules were analyzed by ultrasound and classified by using both ACR TIRADS® and Alpha Score;fine-needle aspiration biopsy was performed when needed and classified with Bethesda. The relationships between predictors were analyzed by using binary logistic regression, statistical significance was defined by a p-value of 0.05, with an error margin of 4% and 95% confidence intervals. Results: Alpha Score 2.0 establishes five types of malignant predictors: microcalcifications, irregular borders, taller-than-wide shape, predominant solid texture and hypoechogenicity;a diameter equal to or greater than 1.5 cm adds an extra point to the final score. Resulting classification divides TNs into 4 categories: benign (1.9%), low suspicion (8.7%), mild suspicion (13.6%) and high suspicion (75.7%) of malignancy probability;sensitivity of 82%, specificity of 74%, the positive predictive value of 94%, the negative predictive value of 51%, the statistical accuracy of 81%, odds ratio of 108.89 and correlation with ACR TIRADS of 0.77 and Bethesda of 0.91. Conclusions: Alpha Score 2.0 has superior diagnostic accuracy and performance compared to the previously published Alpha Score and is able to classify a benign TN in a precise, safe and accurate way, avoiding unnecessary FNABs or determining the necessity of FNAB in cases of moderate to high suspicion of malignancy.
