RESUMO
The aim of this study was to evaluate the use of the running anaerobic sprint test (RAST) as a predictor of anaerobic capacity, compare it to the maximal accumulated oxygen deficit (MAOD) and to compare the RAST's parameters with the parameters of 30-s all-out tethered running on a treadmill. 39 (17.0±1.4 years) soccer players participated in this study. The participants underwent an incremental test, 10 submaximal efforts [50-95% of velocity correspondent to VO(2MAX) (vVO(2MAX))] and one supramaximal effort at 110% of vVO(2MAX) for the determination of MAOD. Furthermore, the athletes performed the RAST. In the second stage the 30-s all-out tethered running was performed on a treadmill (30-s all-out), and compared with RAST. No significant correlation was observed between MAOD and RAST parameters. However, significant correlations were found between the power of the fifth effort (P5) of RAST with peak and mean power of 30-s all-out (r=0.73 and 0.50; p<0.05, respectively). In conclusion, the parameters from RAST do not have an association with MAOD, suggesting that this method should not be used to evaluate anaerobic capacity. Although the correlations between RAST parameters with 30-s all-out do reinforce the RAST as an evaluation method of anaerobic metabolism, such as anaerobic power.

The lymphatic sump of Borrie is an important area of regional node metastasis in each lung. The sump area is of increased importance on the right side, since bilobectomy has been recommended to ensure complete removal of lymphatic disease in patients with lower or middle lobe carcinoma. The role of bronchoscopy in assessing lymphatic metastasis of bronchial carcinoma was investigated in 42 patients at the North Carolina Memorial Hospital. Because of the high incidence of associated lymphatic metastases, bilobectomy is indicated for right lower or middle lobe lesions observed at bronchoscopy. Simple lobectomy may be utilized when bronchoscopic findings are negative and when there is no involvement of the lymph nodes of the sump of Borrie at the time of operation. If there is gross nodal involvement of the lymphatic sump, pneumonectomy will be required.

A retrospective study of 49 patients with chronic obstructive and chronic calcific pancreatitis is presented. All patients were operated upon and underwent either a partial pancreatectomy or internal drainage of the ductal system into a Roux-en-Y loop of jejunum. The criteria for selection of operation are discussed, and the follow-up of the two operative groups is given. In patients selected as described, internal drainage provided better relief of pain and was accomplished with a lower operative mortality and morbidity and with less postoperative pancreatic insufficiency.
