  • Guillain-Barré Syndrome

    Abstract In this study, we tried to describe the characteristics of pain and explore the association between the incidence of pain and abnormal laboratory test results in patients during the acute phase of Guillain-Barré syndrome (GBS).This retrospective cohort study enrolled 252 patients with GBS who were in the[…][ncbi.nlm.nih.gov]

  • Diabetic Amyotrophy

    Abstract A 16-year-old boy with insulin-dependent diabetes mellitus since age five years was admitted with severe ketoacidosis, and suffered a cardiorespiratory arrest from which he made a full recovery. He subsequently developed the typical clinical picture of diabetic amyotrophy with painful asymmetrical weakness[…][ncbi.nlm.nih.gov]

  • Paraneoplastic Polyneuropathy

    Mildly decreased tone in the right foot. Deep tendon reflexes been 2 and equal bilaterally in the upper extremities, reduced bilateral patellar and absent at the ankles.[ispub.com] Sensory examination showed decreased pin sensation bilateral up to the mid-thighs and mid-arms bilaterally.[ispub.com]

    Deep tendon reflexes (biceps, brachioradialis, triceps, patellar, and Achilles) were 3 bilaterally. Plantar responses were upgoing bilaterally.[clinicaladvisor.com] Sensory exam showed decreased vibration and joint-position perception over the toes (right more than left).[clinicaladvisor.com]
