Patients with frequent episodes of paroxysmal atrial fibrillation (AF) are prone to develop permanent AF and have an increased thromboembolic risk. We have previously shown that P wave dispersion (P dispersion), defined as the difference between the maximum and the minimum P wave duration, and maximum P wave duration (P maximum) can distinguish patients(More)
We present a case of bilateral Morgagni hernia in a 68-year-old male with an intermittent history of progressive onset of breath shortness and occasional cardiac arrhythmias. Diagnosis was made by clinical examination and the findings in a plain chest radiograph and was confirmed by computed tomography scan. The patient was operated electively and subjected(More)
AIM To investigate whether the frequency and distribution of mast cells (MCs) in pleomorphic adenomas (PAs) of major and minor salivary glands justifies the suggestion that there exists an association between MCs and mucoid stromal changes in PAs. METHODS The material consisted of 22 cases of pleomorphic adenoma (eight arising in major and 14 in minor(More)
"Silent Sinus Syndrome" is a quite rare condition of otherwise asymptomatic maxillary sinusitis that presents with enophthalmos. Despite the fact that the "Silent Sinus Syndrome" presents with enophthalmos, these patients are finally treated by the otorhinolaryngologist, who should be familiar with this condition, in order to facilitate prompt diagnosis and(More)
Meningoencephaloceles are herniations of brain tissue through dehiscences of the skull base. These skull defects are either acquired (otologic infection, trauma, surgery, neoplasia) or spontaneous. Spontaneous temporal bone meningoencephaloceles are quite rare conditions, usually congenital in origin presenting during childhood, and only occasionally(More)
Congenital hepatic fibrosis belongs to the fibrocystic diseases of the liver and represents ductal plate malformation of interlobular bile ducts, along with a destructive cholangiopathy associated with fibrosis. Four patients with congenital hepatic fibrosis are described. Their median age at presentation was 25 years; none of them had a family history of(More)
AIM Spur cell anemia (SCA) is a form of acquired hemolytic anemia seen in patients with advanced cirrhosis and particularly in patients with alcoholic cirrhosis. The aim of the present study was to evaluate the incidence of spur cells and spur cell anemia in patients with advanced liver disease and to correlate the presence of spur cell anemia with(More)
Hyaluronan accumulates at sites of inflammation, which affects the organization of matrix and thereby the proliferation, migration, and adherence of cells. In this study we investigated possible beneficial effects of the hyaluronan-degrading enzyme hyaluronidase on rat liver graft viability. Orthotopic rat liver transplantation was performed using a cuff(More)
Midgut volvulus as a result of malrotation classically presents in early life and is associated with intestinal obstruction and compromised vascular supply of the gut. On rare occasions this condition may manifest itself in teenagers and adults, often with disastrous outcome. We report a 28-year-old patient who presented with maelena and endoscopy showing(More)
BACKGROUND Nucleos(t)ide analogues (NAs) constitute the backbone of treatment for the prevention of hepatitis B virus recurrence after liver transplantation (LT). Decline in serum phosphorus levels is a common side effect of nucleotide therapy. Our aim was to assess the impact of nucleotide treatment on the occurrence of hypophosphatemia after LT and(More)
