Introduction: Subclavian steal syndrome refers to the reversal of vertebral blood flow in the setting of proximal subclavian or innominate artery severe stenosis or occlusion resulting in the symptoms of vertebrobasilar insufficiency related to exercise of the upper extremities. It is more common on the left side. Case report: We reported a case of subclavian steal syndrome on the right side in...

Trigeminal trophic syndrome (TTS) is an uncommon condition characterised by anaesthesia, paraesthesias and ala nasi ulceration, following peripheral or central damage to the trigeminal nerve. Only about 100 cases have been described in the literature to date. We report a 74-year-old woman who presented with a right cheek ulcer accompanied by pruritus and paraesthesia for three months. An old ri...

Liver function and serum concentrations of rifampicin, a highly cholephilic antibiotic, have been studied after ingestion of a single dose of 600 mg of rifampicin in 12 patients, six of them having a normal liver and six a cirrhotic, and during treatment with 600 mg of rifampicin per day for 17 days in eight patients, four of them having a normal liver and four a cirrhotic. Rifampicin produced ...

1t has been demonstrated that continuous administration of heparin during pregnancy results in an improvement of placental insufficiency [l, 2, 3, 4, S]. This is based on the assumption that the nutritional insufficiency is caused maintained by a disturbance in the microcirculation due to platelet aggregation and fibrin deposits. By inhibiting these coagulation processes the disturbances of met...

The external symptoms of suprarenal insufficiency in cats with diabetes insipidus are the same as in those animals with only the suprarenals removed, except that the symptoms develop more rapidly in the former. The serum electrolyte changes, however, are different; there is no consistent or marked decrease in the concentration of sodium or chloride following suprarenalectomy in cats with diabet...

Background: Clinical information about stroke in the vertebrobasilar territory has lagged behind that for anterior circulation syndrome. This is the first report from posterior circulation syndrome registry in Iran. Methods: Consecutive patients with brain infarction in vertebrobasilar territory admitted to Ghaem hospital, Mashhad were enrolled in a prospective study during 2006-2007. Diagnosis...

Bow hunter's syndrome (BHS), also known as rotational vertebral artery (VA) occlusion syndrome, is a rare yet treatable type of symptomatic vertebrobasilar insufficiency resulting from mechanical occlusion or stenosis of the VA during head and neck rotation or extension. The symptoms of BHS range from transient vertigo to posterior circulation stroke. The underlying pathology is dynamic stenosi...

The vertebral artery test (VAT) is often used during the physical therapy examination but its validity as a clinical test of arterial patency is a topic of debate. When examining patients with dizziness, a modified VAT (mVAT) is routinely used to minimize angular changes of the ear limiting stimulation of the vestibular system. The mVAT can be helpful in the differential diagnostic process as d...

Vertebral artery injury including thrombosis, arteriovenous fistula (AVF), pseudo-aneurysm and hemorrhage may be iatrogenic or due to penetrating or blunt trauma. Although mostly asymptomatic, vertebral artery injury may also present with vertebrobasilar insufficiency findings, cephalgia, radicular pain or myelopathy due to blockade of arterial flow, arterial steal phenomenon and venous hyperte...
