The authors describe the demographics, clinical presentation, investigation, treatment, and outcomes of pediatric patients with Guillain-Barré syndrome. They identified 35 pediatric patients with Guillain-Barré syndrome presenting to a tertiary academic center over a 20-year period. The most common presenting symptoms were paresthesias (54%), weakness… (More)
Cerebral vasculopathy is an important but underrecognized complication of neurofibromatosis type 1. Over a 10-year period, we retrospectively assessed the prevalence, clinical manifestations, management, and outcome of cerebral vasculopathy in children with neurofibromatosis type 1. Magnetic resonance imaging (MRI) of the brain was performed on 78% of the… (More)
The refinery at Malelane is currently evaluating refining technologies other than the existing carbonatation and sulphitation processes with a view to improving decolourisation. As part of this programme, and following successful laboratory trials at the Sugar Milling Research Institute (SMRI) with ozone decolourisation of refinery melt, a full scale trial… (More)
Hirayama disease has been mainly reported from Asia; only a few cases are from the Western hemisphere, particularly North America. This is a retrospective chart review of patients < 18 years, diagnosed with Hirayama disease from a single center over 10 years. We diagnosed 6 children (4 boys), 15.1 ± 1.2 years of age. Symptom onset was 3 months to 3 years… (More)
FIGURE 1 Mode of interaction of Talofloc with colourant. Experimental Talocarb (dimethylamine polymer), an FDA approved colour precipitant, when dosed to final carbonatated liquor immediately before filtration at a dosage rate of about 200 ppm on liquor solids, was found to increase the dec0 lour-isation over carbonatation by 25-30% (Trot, 1988). The… (More)
The refinery at Malelane has in the past produced refined sugar for the consumer market. A decision was taken by the management of Transvaal Sugar (TSB) to produce a quality of refined sugar that would also be acceptable to the industrial and the export markets. The processes that were evaluated and implemented at the Malelane refinery during the past three… (More)
The operculum syndrome, not previously documented as a complication of tuberculous meningitis, is described in a three-year-old African boy. The appearance on CT scan correlates radiographically with anatomical descriptions of the operculum syndrome, and is useful in distinguishing the condition from pseudobulbar palsy.
