No influence of immigrant background on the outcome of total hip arthroplasty. 140,299 patients born in Sweden and 11,539 immigrants in the Swedish Hip Arthroplasty Register.

Background And Purpose: Total Hip Replacement (THA) is one of the most successful and cost-effective operations. Despite its benefits, marked ethnic differences in the utilization of THA are well documented. However, very little has been published on the influence of ethnicity on outcome.

Fatality, morbidity and quality of life in patients with refractory angina pectoris.

Background: Refractory angina pectoris has been defined as coronary artery disease and severe angina, not available for further conventional pharmacological treatment or for revascularization procedures. The aim of the study was to assess fatality, morbidity and quality of life in patients with refractory angina.

Methods: Patients with refractory angina were prospectively identified at seven centres and were compared with an age and gender matched group of patients accepted for revascularization due to severe angina.

White matter disease in magnetic resonance imaging predicts cerebral complications after coronary artery bypass grafting.

Background: The aim of the present study was to assess neurologic and neuropsychologic complications in 104 patients randomized to coronary artery bypass grafting or spinal cord stimulation. An additional objective of the study was to assess whether preoperative white matter disease might predict cerebral complications, as previous studies have shown that there is a relationship between white matter disease and neuropsychologic decline after coronary artery bypass grafting.

Methods: The patients were subjected to neurologic examination before and six months after intervention.

Feasibility of spinal cord stimulation in angina pectoris in patients with chronic pacemaker treatment for cardiac arrhythmias.

Spinal cord stimulation (SCS) has been used since 1985 as additional symptom-relieving treatment for patients with severe angina pectoris despite optimal conventional medical and invasive treatment. SCS has antiischemic effects and is safe and effective in long-term use. Several patients with coronary artery disease also suffer from disorders that necessitate the use of a cardiac permanent pacemaker (PPM).

Temporary cessation of spinal cord stimulation in angina pectoris-effects on symptoms and evaluation of long-term effect determinants.

Background: Spinal cord stimulation (SCS) has been used since 1985 for patients with refractory angina pectoris. Spinal cord stimulation has anti-ischaemic effects and reduces angina effectively. After long-term treatment, temporary cessation of stimulation may occur due to SCS battery depletion or electrode fracture.

Pain as presenting symptom in Lyme neuroborreliosis.

Neurogenic pain with radiculitis is often the starting symptom in adult patients with tick-borne Lyme neuroborreliosis and in some cases the only clinical manifestation. Cranial paresis and other neurologic signs usually occur after the onset of pain. The present paper describes four patients who had severe pain as the main presenting symptom of Lyme neuroborreliosis.
