Systemic sclerosis (SSc) is characterized by thickening and fibrosis of skin and internal organs that is associated with vascular damage. SSc may lead to arterial dysfunction and premature aging of the arteries. However, its relationship with parameters of arterial wall dysfunction has not been fully explored. To determine if carotid-radial pulse wave velocity (PWV), aortic augmentation index (AIx) and endothelial function are altered in SSc patients, 17 consecutive patients with SSc and 34 age- and gender-matched controls were included in our study. PWV and AIx were assessed non-invasively by applanation tonometry. The endothelium-dependent flow-mediated dilatation (FMD) test in a brachial artery was performed by the ultrasound system. The blood investigations included serum lipid profile, glucose, and high-sensitivity CRP (hsCRP) measurements. As compared to controls, SSc patients had significantly higher medians of the AIx (p = 0.002) and the PWV (p = 0.04) and the median of the FMD was significantly lower (p = 0.001). Stepwise linear regression including comorbid factors showed that SSc was a significant independent predictor of all arterial wall parameters measures. SSc patients have increased AIx and PWV and lower FMD as compared to control subjects. The relationship between SSc and measures of arterial wall parameters still remains unclear. Though replication of the results presented here is required, we conclude that SSc has a great impact on large and conduit arteries damage.

We evaluated in this prospective study the effectiveness of continuous thoracic epidural anesthesia (TEA) and postoperative analgesia with ropivacaine and compared it with general anesthesia (GA) and opioids for pain relief, side effects, postanesthesia recovery, and hospital discharge after modified radical mastectomy. Sixty ASA physical status II and III patients undergoing mastectomy were randomly assigned to two study groups of 30 patients each. In the TEA group, an epidural catheter was inserted at T6-7, and 5--10 mL of 0.2% ropivacaine was injected to maintain anesthesia and to continuously administer adequate analgesia for 48 h. GA was induced with IV 1--2 mg of midazolam or 50--100 microg/mL of fentanyl followed by 50--150 mg of propofol and was maintained with sevoflurane and 50% N(2)O in oxygen. The Aldrete score system was used to evaluate postanesthesia recovery, a verbal rating scale was used for assessment of pain intensity, and a postanesthesia discharge scoring system was used for discharge home. The demographic data and side effects (except for nausea and vomiting) (GA 43%, TEA 10%, P = 0.0074) and discharge home were similar in both groups. However, the number of patients ready for discharge from the recovery room during the first postanesthesia hour (Aldrete score of 10) was significantly larger after TEA (80%) than after GA (33%) (P = 0.0006). GA patients experienced significantly more (P < 0.001) substantial pain than TEA patients on Day 0 (70%), Day 1 (53%), and Day 2 (27%) after the surgery. Patient satisfaction was greater with TEA (70%) than with GA (30%) (P < 0.001). We conclude that TEA with ropivacaine provides better postoperative pain relief and less nausea and vomiting, facilitates postanesthesia recovery, and gives greater patient satisfaction than GA.
