We reported a 3-year-old girl with myoclonus epilepsy associated with ragged-red fibers (MERRF) who was afflicted with recurrent pain attacks and allodynia on the right side of the body. Although magnetic resonance imaging showed normal intensity in the thalamus, single-photon emission computed tomography (SPECT) revealed hypoperfusion in the thalamus. Somatosensory evoked potentials showed delayed early cortical responses, particularly on right median nerve stimulation. The parenteral administration of cytochrome c with flavin mononucleotide and thiamine diphosphate abolished the intolerable pain. This clinical improvement was objectively supported by the results of SPECT and neurophysiological findings. These observations suggested that a dysfunction of the thalamus was responsible for her pain and that cytochrome c therapy was of benefit for this symptom.

OBJECTIVES: Validated, noninvasive studies were used to compare sensation and motor function of the upper gastrointestinal tract in adolescents with functional dyspepsia (FD) and in control subjects. STUDY DESIGN: Fifteen adolescents with FD and 15 healthy participants underwent standardized symptom assessment, a satiation nutrient drink test, and 13 C-Spirulina platensis breath test for gastric emptying of solids. Adolescents with FD also underwent measurements of fasting and postprandial gastric volume by means of single-photon emission computed tomography, and their results were compared with those from 15 healthy volunteers (age, 18 to 25 years). RESULTS: Compared with control subjects, adolescents with FD had significantly higher postprandial symptoms 30 minutes after reaching maximum satiation with the nutrient drink test and significant delay in the T 1/2 for gastric emptying of solids. Compared with healthy 18- to 25-year-old adults, adolescents had a diminished postprandial gastric volume response. By means of single-photon emission computed tomography, frequent baseline dyspeptic symptoms were associated with prolonged T 1/2 for gastric emptying and higher postprandial aggregate symptom score. A baseline increased severity of dyspepsia symptoms was associated with prolonged T 1/2 for gastric emptying. CONCLUSIONS: Adolescents with FD demonstrate increased postprandial symptoms after challenge, delayed gastric emptying, and a reduced gastric volume response to feeding.
