Diabetic amyotrophy also known as Bruns-Garland syndrome is diabetic neuropathy subtype affecting the lumbosacral nerve roots and peripheral nerves. There is an ongoing debate on the pathophysiology behind this condition whether is it ischaemic, metabolic (hyperglycaemia) or inflammatory. A 36-year-old man with uncontrolled diabetes mellitus complained of unprovoked weight lost and right proximal thigh discomfort with weakness for one week duration. In neurological examination, his right hip flexion was at medical research council (MRC) grade 3, right hip extension MRC grade 4, his knee and ankle flexion and extension are normal (MRC grade 5). The muscle tones and reflexes were normal. Sensation and proprioception were intact bilaterally. Nerve conduction study (NCS) showed markedly reduced amplitude of the compound muscle action potentials and sensory nerve action potentials, while conduction velocities show only mild slowing. He was started on a course of oral prednisolone 10 mg daily and improved gradually. At three months follow-up, his right lower limb power has recovered fully and he can walk without any assistance. Diabetic amyotrophy was confirmed by suggestive clinical features supported by electrophysiological findings of the affected nerves. This condition is due to metabolic derangement and vasculopathy or immune mediated nerve injury. So, the healthcare providers should be aware about this rare complication of diabetes.
Primary pleural melanoma is a very rare condition
and highly aggressive tumour. A patient presented
with productive cough, haemoptysis, pluritic chest
pain and breathlessness. On investigation, she was
diagnosed as left-sided lung mass with pleural
effusion. Pleural biopsy confirmed malignant
melanoma of pleura and she was subsequently
referred to the oncology team for palliative
chemotherapy. In conclusion, primary pleural
melanoma remains a rare disease with no proven
effective treatment regime available.
Mild sleep deprivation is widespread in many societies worldwide. Electroencephalography (EEG) microstate analysis provides information on spatial and temporal characteristics of resting brain network, serving as an indicator of neurophysiological activities at rest. This study seeks to investigate potential neural markers in EEG following mild sleep deprivation of a single night using EEG microstate analysis. Six-minute resting EEG was conducted on thirty healthy adults within 6 hours of waking in the morning and after at least 18 h of sleep deprivation. Translated and validated Malay language Karolinska Sleepiness Scale was used to assess the participants' degree of sleepiness. Microstate characteristics analysis was conducted on the final 24 subjects based on four standard microstate maps. Microstate C shows a significant increase in mean duration, coverage and occurrence, while microstate D has significantly higher occurrence after sleep deprivation. This study demonstrates notable changes in resting state EEG microstates following mild sleep deprivation. Present findings deepen our understanding of the brain's spatiotemporal dynamics under this condition and suggest the potential utility of neural markers in this domain as components of composite markers for sleep deprivation.
