The explanations for the emergence of cryptogenic fibrosing alveolitis as a new clinical entity during the second half of the 20th century are unclear. The authors have previously reported evidence of an increased risk of cryptogenic fibrosing alveolitis in relation to the use of antidepressant drugs. The authors have now tested this hypothesis a priori in an analysis of computerized general pr...
BACKGROUND/AIMS Many patients are diagnosed with cryptogenic hepatocellular carcinoma (HCC) without metabolic syndrome (MS). We investigated the risk factors for cryptogenic HCC in patients with a low body mass index (BMI) or without MS. METHODS Thirty-six patients were diagnosed with cryptogenic HCC over a 10-year period at a tertiary research hospital. Data including BMI score and risk fact...
AIM To assessed the effect of liver cirrhosis (LC) on the poorly understood long-term mortality risk after first-ever mechanical ventilation (1-MV) for acute respiratory failure. METHODS All patients in Taiwan given a 1-MV between 1997 and 2013 were identified in Taiwan's Longitudinal Health Insurance Database 2000. Each patient with LC was individually matched, using a propensity-score metho...
UNLABELLED We aimed to investigate the incidence of occult hepatitis B infection (OBI) in patients with "cryptogenic" hepatocellular carcinoma (HCC) and to study the HBV replicative activity in these patients. Tumorous and adjacent nontumorous liver tissues were obtained from 33 cryptogenic HCC patients and 28 HCC patients with identifiable causes (13 with chronic hepatitis B [CHB], six with ch...
BACKGROUND & OBJECTIVES There are only a few studies on aetiology of portal hypertension among adults presenting to tertiary care centres in India; hence we conducted this study to assess the aetiological reasons for portal hypertension in adult patients attending a tertiary care centre in southern India. METHODS Causes of portal hypertension were studied in consecutive new adult patients wit...
the coexistence of waldenstromâ´s macrglobulinemia and cryptogenic cirrhosis has been rarely reported.we describe a 72-year-old man with compensated cryptogenic cirrhosis whose major clinical presentation was hyperviscosity syndrome. serum protein electrophoresis revealed the presence of an igm-kappa spike. lambda light chain was found in urine. bone marrow biopsy was performed, which showed at...
The presence of a patent foramen ovale (PFO) has been found to be associated with an increased risk of cryptogenic stroke in many case-control studies. This paper reviews the current understanding of the pathophysiology and diagnosis of PFO, and therapeutic options of patients with PFO and cryptogenic stroke.
Rationale: Data on hemoptysis of unknown origin (i.e., “cryptogenic”) are scarce and the outcome of patients affected is controversial. Objectives: To describe the clinical spectrum and course of patients with cryptogenic hemoptysis, as well as pathologic findings when surgery is performed. Methods: A cohort of 81 patients referred for cryptogenic hemoptysis after clinical evaluation, chest rad...
Objective: To report the distinctive clinical features of cryptogenic new-onset refractory status epilepticus (C-NORSE) and the C-NORSE score based on initial clinical assessments. Methods: A retrospective studywas conducted for 136 patients with clinically suspected autoimmune encephalitis who underwent testing for autoantibodies to neuronal surface antigens between January 1, 2007, and August...
Cryptogenic (of unknown cause) ischaemic strokes are now thought to comprise about 25% of all ischaemic strokes. Advances in imaging techniques and improved understanding of stroke pathophysiology have prompted a reassessment of cryptogenic stroke. There is persuasive evidence that most cryptogenic strokes are thromboembolic. The thrombus is thought to originate from any of several well establi...
