Clinical Scenarios in Chronic Kidney Disease: Chronic Tubulointerstitial Diseases.

Clinical Scenarios in Chronic Kidney Disease: Chronic Tubulointerstitial Diseases. Contrib Nephrol. 2016;188:108-19 Authors: Meola M, Samoni S, Petrucci I Abstract Chronic tubulointerstitial diseases are a common final pathway toward chronic renal failure regardless the primary damage (glomerular, vascular or directly the tubulointerstitium). Chronic tubulointerstitial nephritis (CTN) is characterized by interstitial scarring, fibrosis and tubule atrophy, resulting in progressive chronic kidney disease. Most frequent causes of CTN are drugs, heavy metals, obstructive uropathy, nephrolithiasis, reflux disease, immunologic diseases, neoplasia, ischemia, metabolic diseases, genetics and miscellaneous. At ultrasound (US), kidneys' morphological aspect is similar in all forms of chronic interstitial nephropathy and only chronic pyelonephritis with or without reflux shows distinguishing characteristics. In interstitial nephropathy, kidneys' profiles are finely irregular and corticomedullary differentiation is altered because of a diffused hyperechogenicity. The only indirect sign of chronic interstitial damage can be derived from the value of intrarenal resistive indexes that hardly overcome 0.75. US is mandatory in clinical chronic pyelonephritis work-up because it provides information on kidney's diameter and on growth nomogram in children. Renal profiles can be more or less altered depending on the number of cortical scars and the presence of pseudonodular a...

ConclusionsResidual incompetent tributaries after treatment of varicose veins will increase the reintervention rate in the long term, as much as leaving a trunk vein untreated. Patients should be informed about the increased risk of reintervention if not all incompetent veins are targeted.

ConclusionCongenital piriform sinus fistula is an important cause of deep neck abscess in children. The presence of purulent gas-liquid equilibrium or air shadow in cervical-enhanced computed tomography or ultrasound suggests a high possibility of the presence of an internal fistula, and endoscopic low temperature ablation can be done at the same time as the diagnostic endoscopy.ResumoIntroduçãoA fístula congênita do seio piriforme é uma doença relativamente rara na prática clínica; a maioria se manifesta na infância; entretanto, os médicos geralmente t&ec...

Conclusion: It may be employed either alone or in combination with cryotherapy, existing chemotherapy, bypass surgery or radiations to achieve the optimal results in these patients. Nevertheless, there is a need to formulate a uniform dose and procedure to achieve homogeneity and develop references for clinical practices. PMID: 31977258 [PubMed - as supplied by publisher]

Authors: Orsini D Abstract Poverty, high population density and unhealthy dwellings in Siena's historic district accounted for the spread of tuberculosis in its various forms between the mid-nineteenth century and the first three decades of the twentieth century. In this paper, the author relies on statistical data relating to a time span between 1898 and 1935 to discuss the high incidence of scrofula, or tuberculosis of the lymphatic glands, among Siena's infant population.The result is a description of the most important actions implemented at city level to prevent tuberculosis and to assist and treat sick childr...

Therefore, the development of novel fluorescent materials with both excellent photostability and biodegradability is of great significance for further broadening their application in numerous research fields. In this work, Nb2C quantum dots (Nb2C QDs) with pristine cryst...

We describe an automatic natural language processing (NLP)-based image captioning method to describe fetal ultrasound video content by modelling the vocabulary commonly used by sonographers and sonologists. The generated captions are similar to the words spoken by a sonographer when describing the scan experience in terms of visual content and performed scanning actions. Using full-length second-trimester fetal ultrasound videos and text derived from accompanying expert voice-over audio recordings, we train deep learning models consisting of convolutional neural networks and recurrent neural networks in merged configuratio...
