Limited insights into the pathophysiology of the atherosclerotic carotid stenosis are available in vivo. We conducted a prospective study to assess safety and feasibility of intravascular ultrasound (IVUS) combined with near-infrared spectroscopy (NIRS) in carotid arteries. In addition, we described the size and the distribution of lipid rich plaques in… (More)
UNLABELLED Cardiological investigation of 23 children (13 boys) with sliding hiatal hernia revealed mitral valve prolapse in 18 patients (10 boys) suggesting a very high association rate of 78.2%. No other signs of connective tissue weakness were seen. CONCLUSION Cardiological evaluation is recommended in every child with hiatal hernia.
The term vulnerable atherosclerotic plaque is used to describe an atherosclerotic lesion with a high probability of rupture and thrombosis causing an acute coronary event or stroke. Pathogenesis of the vulnerable plaque has been well described pathologically and on experimental models. Detection of vulnerable plaques in vivo has been limited so far. There… (More)
Mitral valve prolapse and severe gastroesophageal reflux with hiatal hernia were found in a girl aged 2 years, 4 months with Cohen syndrome. The clinical manifestations suggest the presence of a connective tissue disorder in the patient.
A large-scale, double-stream gas puff target has been illuminated by sub-kJ, near-infrared (NIR) focused laser pulses at the PALS facility (Prague Asterix Laser System) to produce high-energy pulses of soft X rays from hot, dense plasma. The double-puff arrangement ensures high gas density and conversion efficiency from NIR to X rays approaching that… (More)
Non-Hodgkin lymphoma (NHL) is the second most frequent malignant tumor in the head and neck, squamous cell carcinoma being the most frequent. NHL often appears in extranodal localisations. In the head and neck, two distinct extranodal sites are recognised: extranodal lymphatic localisations or involvement of the ring of Waldeyer, and extranodal… (More)
OBJECTIVES This study sought to evaluate the effect of catheter-based patent foramen ovale (PFO) closure on the occurrence of arterial bubbles after simulated dives. BACKGROUND PFO is a risk factor of decompression sickness in divers due to paradoxical embolization of bubbles. To date, the effectiveness of catheter-based PFO closure in the reduction of… (More)
We report two cases of extranodal extralymphatic non-Hodgkin lymphoma presenting as a mandibular swelling. In one case the masseter muscle was involved, suggestive of a non-epithelial process. In the other case the mandible was involved by a mixed osteolytic bone process. Extranodal non-Hodgkin lymphoma should be considered when dealing with a mass lesion… (More)
Patent foramen ovale (PFO) is associated with an increased risk of decompression sickness (DCS) in divers that results from a paradoxical embolization of nitrogen bubbles. The number of scuba divers worldwide is estimated in the millions, and the prevalence of PFO is 25%-30% in adults. It is interesting that despite these numbers, many important issues… (More)
