Early diagnosis in post-traumatic complex regional pain syndrome.

Since prospective studies confirmed an incidence of >10% of complex regional pain syndrome complication in patients after distal radial fracture, early diagnosis is important. Therapy should be commenced immediately with a systematic approach to avoid chronicity of the disease. Despite this, epidemiological studies revealed an extreme delay in effective treatment among complex regional pain syndrome patients, who were repeatedly referred to different physicians and often treated inadequately before being referred to specialized pain clinics.

Muscle pain in myophosphorylase deficiency (McArdle's disease): the role of gender, genotype, and pain-related coping.

Pain characteristics were examined in 24 patients with myophosphorylase deficiency (McArdle's disease). Pain parameters were related to mutation analyses as well as psychosocial data using a pain questionnaire including an assessment of psychosocial distress and coping measures (Beck Depression Inventory BDI; Kiel Pain Inventory KPI, Multidimensional Fatique Inventory MFI). Twenty-three patients complained of pain, which was intermittent and exercise-induced in 15 patients.

Heparan sulfate proteoglycans interact exclusively with conformationally intact HPV L1 assemblies: basis for a virus-like particle ELISA.

In this article, we demonstrate that interaction of human papillomavirus-like particles (HPV-VLPs) with the putative glucosaminoglycan binding receptor is strictly dependent on conformational integrity. Such conformations are present on VLPs and capsomeres but not on monomers of the major capsid protein, L1, confirming reports that capsomeres can induce virus-neutralizing antibodies. Furthermore, we show the suitability of this specific interaction for development of VLP-based enzyme-linked immunosorbent assays (ELISAs), using heparin for indirect coupling of VLPs to microtiter plates, which may add an intrinsic quality control.

Repetitive visual stimulation: a neuropsychological approach to the treatment of cortical blindness.

Cortical visual disturbances can occur after traumatic or ischemic brain lesion. Patients mostly suffer from hemianopia. Different treatment approaches in patients with hemianopia are being debated with respect to their effectiveness.

Quantitative sensory testing, neurophysiological and psychological examination in patients with complex regional pain syndrome and hemisensory deficits.

Based on bed-side neurological testing, it has recently been shown that 33% of chronic complex regional pain syndrome (CRPS) type I patients exhibit sensory impairments, which extend past the painful area of the affected limb in a hemisensory distribution (Pain, 80 (1999) 95). In the present study, the clinically observed changes in touch and temperature sensations on the side of the body ipsilateral to the affected limb were investigated quantitatively. Neurophysiological and psychological examinations were conducted to detect changes in the peripheral and central nervous system as well as psychopathological abnormalities.
