OBJECTIVE The purpose of this study was to investigate the characteristics of nailfold capillaroscopy associated with hand-arm vibration syndrome (HAVS). METHODS In total, 113 male gold miners were recruited: 35 workers who were chronically exposed to vibration and developed vibration-induced white finger were defined as the HAVS group, 39 workers who were exposed to vibration but did not hav...

Diabetic Retinopathy (DR) is the leading cause of blindness in adults around the world today. Early detection (that is, screening) and timely treatment have been shown to prevent visual loss and blindness in patients with retinal complications of diabetes. The basis of the classification of different stages of diabetic retinopathy is the detection and quantification of blood vessels and hemorrh...

An 11-month-old girl presented to hospital with a massive subdural haematoma and bilateral retinal haemorrhages following an allegedly minor fall. There were no external signs of bruising and no prior bleeding tendency was reported. Although initial analyses were normal, repeated testing of the coagulation-fibrinolysis system led to a diagnosis of mild von Willebrand disease (vWD) Type 1. It wa...

Evidence of damage to cerebral vein walls was sought in 70 cases of multiple sclerosis. Seventy control cases were also examined. The multiple sclerosis cases showed venous intramural fibrinoid deposition (7%), recent haemorrhages (17%), old haemorrhages revealed by haemosiderin deposition (30%), thrombosis (6%) and thickened veins (19%). In all, 41% of all multiple sclerosis cases showed some ...

Shaken baby syndrome is the most common cause of death or serious neurological injury resulting from child abuse. It is specific to infancy, when children have unique anatomic features. Subdural and retinal haemorrhages are markers of shaking injury. An American radiologist, John Caffey, coined the name whiplash shaken infant syndrome in 1974. It was, however, a British neurosurgeon, Guthkelch ...

a total of 200 moribund rainbow trout with clinical signs of a hyperacute haemorrhagic septicemia were collected from rainbow trout farms in fars, kohkiloyeh-boyer ahmad and charmohal-bakhtiari provinces in the south and southwest of iran during summer 2002 to winter 2008 for detection of lactococcus garvieae, the causative agent of lactococcosis. fish kidney samples were cultured aseptically o...

Atrial myxomas are the commonest cardiac neoplasms. The most common extra-cardiac manifestations are embolic infarcts from tumour embolisation. Infrequently, aneurysm formation and intracranial haemorrhages also occur. Incredibly rare are space-occupying lesions and malignant transformation. The authors report a case of a previously healthy middle-aged lady who developed recurrent and expanding...

Cerebral amyloid angiopathy (CAA) is an important cause of primary intracerebral haemorrhage (PICH) in older people, accounting for approximately 10% of all types of PICH. The amount of amyloid deposition in the vessels and vasculopathic changes determine the propensity to PICH. The risk factors of CAA include advanced age and the presence of certain alleles of apolipoprotein E. There are no sp...
