Congenital esophageal stenosis due to tracheobronchial remnants and its associated anomalies.

Two cases of congenital esophageal stenosis due to tracheobronchial remnants are reported, one accompanied by anovestibular fistula and the other by microphthalmos with iris coloboma. A survey of congenital esophageal stenosis due to tracheobronchial remnants in Japan revealed that the incidence of associated anomalies in this lesion is 17.3% This value is significantly lower than that reported for esophageal atresia. Our analysis showed that esophageal atresia is the most frequently associated anomaly, followed by anorectal abnormalities. Cardiovascular anomalies are very uncommon. Embryology relating to this subject is discussed.

Echo guided percutaneous transhepatic cholangiography with puncture transducer.

Conventional percutaneous transhepatic cholangiography (PTC) has some disadvantages because it is customarily performed blindly. If the bile duct is made visible, these disadvantages are eliminated. The biliary tree, if dilated, can be clearly delineated by ultrasound technique. By combining the B-mode examination of the biliary tract with the ultrasonic puncture transducer, percutaneous transhepatic cholangiography was performed successfully in 16 examinations on 12 patients. PTC needle could be inserted directly into the lumen of the bile duct without appreciable difficulty. The echo guided PTC was found to be an easier, safer, and more reliable method than the conventional blind technique.

Improved method for measurement of serum levels of phenobarbital, carbamazepine, primidone and diphenylhydantoin by gas-liquid chromatography.

A gas-liquid chromatographic method for the simultaneous determination of phenobarbital, primidone, carbamazepine and diphenylhydantoin in human serum following therapeutic doses has been developed. After extraction with chloroform, the anticonvulsant drugs were methylated with phenyltrimethylammonium hydroxide in dimethylformamide at 85 degrees C for gas-liquid chromatography. Linear temperature programming of a 1% OV-17 column was used to achieve separation and quantitation. The procedure described in the present paper is relatively simple, highly specific and sufficiently sensitive for use in routine clinical assays.
