Background: Individuals with minor ischaemic stroke and intracranial occlusion are at increased risk of poor outcomes. Intravenous thrombolysis with tenecteplase might improve outcomes in this population. We aimed to test the superiority of intravenous tenecteplase over non-thrombolytic standard of care in patients with minor ischaemic stroke and intracranial occlusion or focal perfusion abnormality.

Patient selection for MT is predominantly based on physiological and imaging parameters. We assessed whether people living with pre-stroke frailty had differing outcomes following MT.
View Article and Find Full Text PDFBackground: Mechanical thrombectomy has revolutionised the treatment of acute ischaemic stroke due to large vessel occlusion. It is well recognised that patients are more likely to benefit when reperfusion happens quickly, however, there is uncertainty as to how best to deliver this service.
Objectives: To compare outcomes of patients in Northern -Ireland who underwent thrombectomy via direct admission to the single endovascular centre (mothership [MS]) with those transferred from primary stroke centres (drip-and-ship [DS]).
A 65-year-old gentleman with stage 5 chronic kidney disease developed an acute posterior circulation stroke, which was treated with intravenous thrombolytic therapy. This was complicated by a retroperitoneal haemorrhage. The patient made an excellent neurological recovery and was discharged to home, independently mobile, having been established on haemodialysis.

Background: Parental stroke increases an individual's risk of stroke, but little is known of the potential value of using this information in targeted screening for primary prevention in general practice.
Method: We sent questionnaires to 300 randomly selected individuals aged 40-65 years, in each of 11 different general practices in Northern Ireland.
Objective: There have been a few reports on long-term remission rates after apparent early remission following pituitary surgery in the management of Cushing's disease. An undetectable postoperative serum cortisol has been regarded as the result most likely to predict long-term remission. Our objective was to assess the relapse rates in patients who underwent transsphenoidal surgery in order to determine whether undetectable cortisol following surgery was predictive of long-term remission and whether it was possible to have long-term remission when early morning cortisol was measurable but not grossly elevated.

Design: A series of single-case studies.
Setting: A stroke rehabilitation unit in Belfast.
The presence and biological significance of circulating glycated insulin has been evaluated by high-pressure liquid chromatography (HPLC), electrospray ionization mass spectrometry (ESI-MS), radioimmunoassay (RIA), receptor binding, and hyperinsulinemic-euglycemic clamp techniques. ESI-MS analysis of an HPLC-purified plasma pool from four male type 2 diabetic subjects (HbA(1c) 8.1 +/- 0.

Our objective was to determine whether Type 1 diabetic patients with microalbuminuria are less sensitive to the effects of insulin on glucose metabolism and skeletal muscle blood flow, compared to those with normal albumin excretion, after careful matching for confounding variables. We recruited 10 normotensive Type 1 diabetic patients with microalbuminuria and 11 with normoalbuminuria matched for age, sex, body mass index, duration of diabetes and HbA(1c). Peripheral and hepatic insulin action was assessed using a two-step euglycaemic hyperinsulinaemic clamp (2 h at 0.

Ethinyl oestradiol/cyproterone acetate is a common agent used to treat the symptoms of PCOS, but its effects on insulin action and insulin pulsatility have not been examined. We investigated the relationship between insulin action and insulin secretion in 11 patients with PCOS, at diagnosis and after 3 months of treatment with ethinyl oestradiol/cyproterone acetate, and in 13 controls.
View Article and Find Full Text PDFObjective: Studies in normal humans and in patients with type 2 diabetes mellitus have demonstrated a close inverse relationship between peripheral insulin sensitivity and the frequency of short-term insulin secretory pulses in the systemic circulation. Our objective was to study this relationship in essential hypertension.
Design: Study of insulin sensitivity and insulin pulse characteristics in hypertensive subjects and normotensive controls using well-established techniques.
Background: after stroke, visual impairment may exacerbate the impact of other impairments on overall disability and negatively influence rehabilitation.
Objective: to examine the visual status of patients after stroke and determine whether this can be improved by simple interventions.
Design: prospective study.
Background: Research into the causes of small-vessel stroke has been hindered by technical constraints. Cases of intracerebral hemorrhage occurring in unusual clinical contexts suggest a causal role for sudden increases in blood pressure and/or cerebral blood flow.
Case Description: We describe a fatal primary thalamic/brain stem hemorrhage occurring in the context of sudden emotional upset.
Aims: It has been suggested that the adverse metabolic effects of antihypertensive therapy offset some of the benefits of blood pressure reduction. It has also been suggested that angiotensin converting enzyme (ACE) inhibitors reduce insulin resistance and that, if used together with thiazide diuretics, the adverse effects of thiazides on insulin sensitivity may be eliminated. We examined the effects on insulin sensitivity of captopril either alone or in combination with bendrofluazide in 11 hypertensive Type 2 diabetic patients.

Design: Randomized, double-blind, placebo-controlled, crossover trial, with 8 week treatment periods of captopril and placebo preceded and separated by 6 weeks of placebo.
Setting: Belfast teaching hospital.
Objective: To compare the efficacy of an extended insulin regimen using correction of hyperketonemia as endpoint with a more conventional regimen in the treatment of diabetic ketoacidosis.
Research Design And Methods: A total of 22 patients admitted to a Belfast teaching hospital with clinical and biochemical features of diabetic ketoacidosis (pH < 7.25 and/or bicarbonate < 16 mmol/l) were randomized to either conventional or extended insulin regimens.
