feet occurring in the character and position of the developing nervous system. The timing of the defect appears to be the seventh week of fetal life. These new findings, especially of vascular and salivary gland hyperplasia, lead to an improved possibility of prenatal genetic counseling. Fetal radiographs, maternal blood chemistry, or amniocentesis determination of glycoprotein titer are recommended as an indicator of hyperplasia of the salivary glands.A. B. Sokol

to prevent the development of hereditary clefts of the lip and palate the influence of vitamin BI during pregnancy was investigated. In rats, clefts were induced by treatment with hydroxamine acids. When thiamine was applied simultaneously the rate of malformations was found to be reduced markedly.--KarlWaag

Ten patients with complete bilateral cleft lip and palate were studied in whom intraoral obturating appliances and extraoral strapping of the prolabium was applied soon after birth for 3 mo. Records were kept in the form of maxillary arch models and cephalometric radiography with the aid of radiopaque markers. Fifty noncleft infants were measured at birth and at 6 mo to give normal values for the linear dimensions studied. In addition, maxillary arch models were randomly selected from the serial records of over 500 normal children. In eight cases, there was successful reduction in premaxillary protrusion as well as the width of the alveolar clefts, prior to surgical repair. Two cases showed disappointing results, for reasons which could not be determined. The studies showed that if the premaxilla is effectively restrained, the lateral segments apparently “catch up” as the face grows forward. In the transverse dimension. the intraoral obturators appeared to prevent any further separation of already displaced lateral segments while also preventing collapse toward the midline of these segments.-,4 B.

Two children with low tracheal narrowing situated just above the carina each required long term tracheostomy management. All standard tracheostomy tubes commercially available were too short to extend beyond the tracheal obstructions. From a thin-walled polyvinyl chloride endotracheal tube the authors constructed a long “custom-made” tracheostomy tube. The upper end of the tube was bivalved to form lateral neck flanges for attachment of tape ties. This long specially modified tube was successful in the management of the two children

Only 46 cases of cervico-mediastinal lymphangiomas were found in the literature. A case is reported of a 24 month old girl, admitted to hospital with severe dyspnea, cyanosis, and asphyxia. The patient presented with a suprasternal swelling extending medially and laterally up the neck. An emergency operation was performed and the cervical part of the lymphangioma was removed first. Two months later. the mediastinal part was removed without too much difficulty. although it was strongly adherent to the mediastinal veins.-C. Monragnani

Giant-cell tumors of the rib are rare in childhood. Pathology. diagnosis. therapy, and prognosis are discussed. In the published case pleural metastases were demonstrated. The tumor was originally benign. In some cases, as shown here, there is a possibility of malignant degeneration. The importance of radical excision is stressed.-Karl-Ludwig Waag Successful Surgical Repair of Congenital
