Oesophageal motility and lower oesophageal sphincter (LOS) competence were investigated in 13 patients with progressive systemic sclerosis (PSS) and in 16 patients with localized scleroderma (LS) by means of oesophageal manometry and 24-h pH monitoring of the distal oesophagus. Results were compared with those of a control group consisting of asymptomatic volunteers. Marked abnormalities in oesophageal motility and in acid exposure in the distal oesophagus were observed in PSS patients only. The mean resting pressure of the LOS was 10.1 +/- 1.5 mmHg in PSS, 21.4 +/- 1.1 mmHg in LS, and 23.8 +/- 2.0 mmHg in asymptomatic controls. Overall sphincter length was 24.1 +/- 3.4 mm in PSS, 31.1 +/- 1.6 mm in LS, and 39.0 +/- 2.0 mm in the control group. Spincter abdominal length was 12.1 +/- 2 mm, 15.4 +/- 1 mm, and 25.0 +/- 1 mm, respectively. The amplitude and duration of oesophageal waves were markedly reduced at 5, 10, and 15 cm above the LOS in PSS patients, with only the upper part of their gullet being spared. An abnormal acid exposure in the distal oesophagus was observed in 84.6% of PSS patients, whereas only 18.2% (2 of 11) of pH-tested LS patients had an abnormal 24-h pH test. These data show that a marked oesophageal involvement is present only in the systemic form of scleroderma. Oesophageal tests may be useful for a circumstantial diagnosis whenever the diagnosis of PSS is uncertain; however, their use does not seem to be justified as routine in patients with LS.

Background: We aimed to assess the ability of comprehensive complication index (CCI) and Clavien-Dindo complication (CDC) scale to predict excessive length of hospital stay (e-LOS) in patients undergoing liver resection for hepatocellular carcinoma. Methods: Patients were identified from an Italian multi-institutional database and randomly selected to be included in either a derivation or validation set. Multivariate logistic regression models and ROC curve analysis including either CCI or CDC as predictors of e-LOS were fitted to compare predictive performance. E-LOS was defined as a LOS longer than the 75th percentile among patients with at least one complication. Results: A total of 2669 patients were analyzed (1345 for derivation and 1324 for validation). The odds ratio (OR) was 5.590 (95%CI 4.201; 7.438) for CCI and 5.507 (4.152; 7.304) for CDC. The AUC was 0.964 for CCI and 0.893 for CDC in the derivation set and 0.962 vs. 0.890 in the validation set, respectively. In patients with at least two complications, the OR was 2.793 (1.896; 4.115) for CCI and 2.439 (1.666; 3.570) for CDC with an AUC of 0.850 and 0.673, respectively in the derivation cohort. The AUC was 0.806 for CCI and 0.658 for CDC in the validation set. Conclusions: When reporting postoperative morbidity in liver surgery, CCI is a preferable scale.

Combination treatment using vibroliposuction and a power-assisted arthroscopic-endoscopic cartilage shaver is an effective treatment for gynecomastia, but the technique has a learning curve. This procedure is most appropriate for patients with grades II and III gynecomastia, or as a first-stage treatment for patients with grade IV gynecomastia.
