Controlled Clinical Trial
Transcutaneous electrical nerve stimulation (TENS) improves upper GI symptoms and balances the sympathovagal activity in scleroderma patients.
To assess the impact of transcutaneous electrical nerve stimulation (TENS) at gastrointestinal (GI) acupoints on GI symptoms and quality of life in scleroderma patients, 17 patients filled out SF-36 and GI symptom questionnaires before the electrocardiogram was recorded for two intervals: baseline and TENS. At home, patients applied TENS for 14 days, then were reassessed. ⋯ Prolonged TENS application normalized the sympathovagal balance (P=0.04), decreased GI symptom scores (P=0.02) and increased the physical functioning score (SF36), which strongly correlated with the change in the sympathovagal balance (r=0.6, P=0.02). In conclusion, TENS at GI acupoints offers a potential option in the treatment of upper GI symptoms, but further study is necessary.

Scurvy is a nearly-forgotten disease in developed countries where adequate nutrition is easily available. It still may occur, however, when, for a variety of reasons, people fail to eat a diet containing adequate vitamin C. We report the case of a 52-year-old patient with depression who developed scurvy.
