Comparative Study[On the surgical treatment of pectus excavatum].
80 cases of funnel chest were treated surgically, 9 by Gross procedure, 41 by turn-over technique and 30 by reverse "V" shape osteotomy of the sternum and ribs with internal fixation. There were 56 boys and 24 girls, with ages ranging from 2 to 14 years. The sternal depression varied in depth from 3 to 4 cm, and in volume from 20 to 120 ml. ⋯ Some disappointing results in the other two techniques, such as uneven chest wall, flat chest and forward protruding of the sternum could also be avoided by this procedure. The internal fixation device was removed one year after operation. Follow-up for 3 to 4 years found the chest wall in satisfactory contour.

[Optimal conditions for the storage of split-thickness skin at 4C].
Split-thickness human skin must, out of necessity, be stored for days to years prior to usage as a burn wound covering. This study was designed to utilized three different parameters of tissue viability in order to determine optimum conditions for skin survival at 4 degrees C for various periods of time in RPMI-1640 media. Viability was determined by 1) trypan blue dye exclusion of trypsinized basal cells (TBC), 2) 14C-leucine incorporation into TBC, and 3) in vitro skin explant growth. Electron microscopy was also done on selected samples. ⋯ RPMI-1640 is an excellent medium for the storage of split-thickness skin at 4 degrees C, 2-4 cm2/ml, for up to 7 days. Because of the high viability retained in skin stored under these conditions, further long term storage in liquid nitrogen should provide good quality tissue for transplantation.

Sixty-five cases of chylothorax treated at the Shanghai Chest Hospital over the past 30 years are reviewed. The causes of chylothorax in this series were mainly traumatic and postoperative (47/65). Two cases were associated with chylopericardium and another 2 with chylous sputum. ⋯ The most favorable site for ligation is immediately above the diaphragm. Over dissection of the thoracic duct should be avoided; (3) The proper surgical approach is on the side of the effusion in unilateral chylothorax, but right side approach is preferred in case of bilateral chylothorax or when the origin of chylous fistula is unknown; (4) Pleurodesis is indicated for those cases if the duct is not obviously present or chyle comes from the pleural lymphatics. Concentrated glucose solution with or without Talc suspension is recommendable.
