This case study describes the long-term after-effects of hydrogen sulphide exposure in a previously healthy 27-year-old male.
Upon hospital admission the patient had a Glasgow Coma Score (CGS) of 3 ; with emergency treatment including hyperbaric oxygen treatments, he progressed to a GCS of 15 on day 7. Although both CT and MRI scans were unremarkable, PET using F-18 deoxyglucose administered 3 years after the accident showed abnormally decreased metabolism bilaterally in the temporal and inferior parietal lobes as well as the left thalamus.
Uptake in the striatum was heterogeneous and abnormal.
A cerebral perfusion study using SPECT performed 3.5 years after the accident revealed bilaterally decreased flow in the putamen but no cortical abnormalities.
Neuropsychological and neurofunctional testing revealed the following impairments : microsmia, psychomotor slowing, extrapyramidal signs and deficits in memory and executive/planning functioning.
These findings are discussed in the context of hydrogen sulphide's known mechanisms of toxicity and the functions of the basal ganglia.
