Interventional radiology and cardiology guarantee high benefits for patients, but are known to be associated with a high level of radiation exposure of medical staff. The recently suggested decrease of the annual dose limit for the eye lens, from 150 to 20 mSv, caused a need for a reconsideration of practices ensuring sufficient protection for the lens of the eyes of medical staff. In such context the study of the scattered radiation around the operator's head could help in finding the best solutions to be adopted for the ceiling-suspended shield and lead glasses in the most common situations in interventional practices...

Percutaneous left atrial appendage (LAA) closure is a routinely performed method to reduce the risk of stroke in patients suffering from atrial fibrillation, when an oral anticoagulation is no longer indicated due to relevant bleeding complications. Currently, the Amplatzer Amulet and the Watchman system are two equally used systems. While there is an acute success rate of more than 95 per cent for this intervention, several minor and major complications such as pericardial effusions, air embolism, vascular lesions in proximity to the heart or even death can occur...

Physicians and Internists in India have tended to brush under the carpet legal issues affecting their profession. Of concern to all Physicians is the judgment in a recent case where the NCDRC has stated that if MD Medicine Physicians write Physician & Cardiologist on their letterhead it is Quackery. What is MD Medicine degree holder in India qualified and trained to treat ? These are issues which need debate and that can only be initiated once we recognize that there is a problem. Either an MD Medicine is a cardiologist or he is not...

Ongoing investigation from the Pediatric Anesthesia NeuroDevelopment Assessment (PANDA) study hopes to examine the long-term effect on cognitive and language development of a single anesthetic exposure in children undergoing inguinal hernia repair. The fifth PANDA Symposium, held in April 2016, continued the mission of previous symposia to examine evidence from basic science and clinical studies on potential neurotoxic effects of anesthetics on developing brain. At the 2016 Symposium, a panel of specialists from nonsurgical pediatric disciplines including anesthesiology, radiology, neurology, gastroenterology, oncology, cardiology, and critical care reviewed use of anesthesia in their practices, including how concern over possible neurodevelopmental effects of early childhood anesthetic exposure has changed discussion with patients and families regarding risks and benefits of imaging studies and interventional procedures involving sedation or anesthesia...

Cardiologists are among the heaviest medical users of ionising radiation. This usage is growing in proportion to the expanding range of cardiac diagnostic tests and interventional treatments. The primary focus of cardiologists is achieving clear diagnoses as well as technically and clinically successful treatments. That has to be set alongside strong awareness of the properties of ionising radiation and associated safety issues. This article illustrates some of the interplay between contemporary cardiology, radiological techniques, cardiology training, and ionising radiation regulations, and aims to set context for training and accreditation of cardiologists who use ionising radiation...

The aim of the present study was to perform cytogenetic analysis by means of a semi‑automated micronucleus‑centromere assay in lymphocytes from medical radiation workers. Two groups of workers receiving the highest occupational doses were selected: 10 nuclear medicine technicians and 10 interventional radiologists/cardiologists. Centromere‑negative micronucleus (MNCM‑) data, obtained from these two groups of medical radiation workers were compared with those obtained in matched controls. The blood samples of the matched controls were additionally used to construct a 'low‑dose' (0‑100 mGy) MNCM‑ dose‑response curve to evaluate the sensitivity and suitability of the micronucleus‑centromere assay as an 'effect' biomarker in medical surveillance programs...

Radiation dermatitis can develop after fluoroscopy-guided interventional procedures. Cases of fluoroscopy-induced radiation dermatitis have been reported since 1996, mostly documented in the fields of radiology, cardiology and dermatology. Since diagnosis and treatment of fluoroscopy-induced radiation dermatitis can be difficult, high grade of suspicion is required. The extent of this reaction is determined by radiation dose, duration of exposure, type of procedure, and host factors and can be aggravated by concomitant use of photosensitizers...
