The authors report on two major complications in 120 percutaneous subclavian catheterizations via the infraclavicular route. One 60-year-old patient recovered from air embolism, and a i7-year-old patient whose catheter was coiled in the superior cava vein developed a superior vena caval obstruction and thrombosis. To prevent air embolism the authors advise the Trendelenburg posi-
This syndrome, usually sporadic, but sometimes familial is described in detail in 12 cases who showed in addition to the three title features, marked nevus flammeus, ear lobe anomalies, other craniofacial dysplasias, visceromegaly of many organs, cytomegaly of the adrenal fetal cortex, renal medullary dysplasia, and polycythemia.

hypertrophy, though not seen in these, is often a feature of the syndrome. The six survivors ( aged 6-10X yr ) were of normal intelligence but had advanced physical development. Their facial appearante is made characteristic by a relative underdevelopment of the maxilla. Infants with this syndrom require recognition and careful follow-up because of the frequency of neonatal hypoglycemia and the possibility of intra-abdominal neoplasia.R. C. M. Cook

PULMONARY VASCULAR RESISTANCEFOLLOWING LUNG REIMPLANTATION AND TRANSPLANTATION. G. R. Daicog, P. D. Allen, and C. J. Streck. Ann. Thorac. Surg. 9: 569-579 (June), 1970. This is a series of canine experiments and discussion of the development of acute pulmonary hypertension following pulmonary implantation. The authors show that it is the distensibility and size of the arterial anastomosis which is most important in the development of pulmonary hypertension in the immediate postoperative period. They clearly distinguish immediate postoperative pulmonary hypertension from late chronic pulmonary hypertension, and clearly state that their experiments were not designed to shed light on the latter.-J.

This is a report of a newborn who, immediately following birth, developed a right tension pneumothorax. Following drainage with an intercostal catheter, he improved, but was noted on X-ray to have air under the right hemidiaphragm. This air resolved spontaneously, the child was fed cautiously, and
he recovered. Cause for the pneumoperitoneum was not discovered, and it is assumed to be secondary to the tension pneumothorax. -.I. G. Rosenkrantz SPONTANEOUS HEMOTHORAX IN THE NEWBORN. B. L. Aaron and D. J. Doohen. Ann. Thorac. Surg. 9:258-262 (March), 1970. This is a report of a full-term infant with respiratory distress who developed a spontaneous left hemothorax with hypoprothrombinemia. He was explored with a presumptive diagnosis of left diaphragmatic hernia, the diaphragm found intact and the hemothorax drained with an intercostal catheter. He recovered with restoration of his prothrombin time. The presumption is that no specific vascular anomaly was present to account for the bleeding, but since the thorax was not explored, this presumption cannot be proved. -1. G. Rosenkrantz PLEURAL EMPYEMA IN CHILDREN. Q. R. Stiles, G. G. Lindesmith, B. L. Tucker, B. W. Meyer, and 1. C. Jones. Ann. Thorac. Surg 10:37-43 (July), 1970. The principles and results of management of empyema have undergone changes over the past 20 years, partly due to changes in the disease, the virulence of its causative organism and antibiotic therapy, and partly following realization that the child with empyema behaves differently than the adult and is frequently able to resolve chronic empyema without aggressive surgery. This is clearly shown in this review of 152 patients with pneumonia and empyema. In the years 19551961, 88 patients (of whom 46 were in the first year of life) were managed by tube drainage (41 patients), and subsequent open drainage ( 23 ) or pulmonary decortication (12 of the 23); from 19621969, 64 patients (of whom only 7 were in the first year of life) were different& managed: tube drainage in 9 with subsequent open drainage in 4 and decortication in 2 of these 4. The predominant organisms were staphylococcus (78 cases) and diplococcus pneumoniae ( 6 cases). Eight patients died during the years 19551961; only one since. Pneumatoceles were frequently present, but the incidence of pneumothorax has dropped markedly (24 cases in 1955-1961; 1 since 1961). At the moment, with better antibiotic con-
