To contribute the early diagnosis of congenital dislocation of the hip, the hip joints of 148 normal newborns and 81 normal infants below 6 months were investigated roentgenographically.
To establish the roentgenographical diagnosis of lateral deviation of the femoral head and to investigate the developmental change of the stability of the normal hip joint after birth, 229 hips were roentgenographed in standard position, in moderately abducted position (15°-30°), in maximally abducted position and in maximally adducted position, and 9 hips of them were roentgenographed in standard position, in 30 degrees internally rotated position and in 30 degrees externally rotated position.
Conclusion
1) To estimate the lateral deviation of the femoral head, author proposed to measure the horizontal distance between the most medial part of the lower end of the ilium (A) and the most medial part of metaphysis of femur (B) of same side (Schenkelhalslippe-Lange) because of clear figure in X-ray.
The distance between the X-ray bulb and focus on the film cassette was fixed in 1 meter, and under this condition, the horizontal distance between A and B was from 7 millimeter to 10 millimeter in normal infant below 6 months, and the mean value of the distance of every month was from 8.2 millimeter to 9.1 millimeter.
These horizontal distances were not changed by the 30 degrees of rotation of the hip, but these horizontal distances increased 1 millimeter by the 10 degrees of abduction and decreased 1 millimeter by 10 degrees of addution.
2) To investigate the developmental change of the stability of hip joint, the horizontal distance between A and B(l) which were changed horizontally by the maximal adduction and the maximal abduction of the hip, and the horizontal distance between A and B(L) in maximally abducted position of the hip were measured, and the stability of the hip joint was estimated by the ratio of l and L.
The developmental change of the stability of the normal hip joint below 6 months was not observed within 6 days after birth, but the developmental change was observed after 7 days, and the hip joint of infant stabilized firmly at about 30 days after birth, and after 1 month the developmental change was not observed anymore.

A case of squamous cell carcinoma of the stomach was reported. A 67 year-old man was hospitalized with complaint of emaciation. Upper GI series revealed a filling defect in the fundus of the stomach. Endoscopic examination was carried out, but fiberscope was unable to be inserted into the stomach. Gastric cancer was suspected, and gastrectomy was performed. Borrmann I type cancer measuring 8×7.5×5 cm was identified in the fundus, extending to the upper portion of the body of the stomach. Histologically, tumor was mostly by squamous cell carcinoma, but partly by adenocarcinoma. Metastasis was not observed. It was postulated that squamous cell metaplasia of adenocarcinoma was contributing in this case.

A surgical interruption of accessory pathway was attempted in a 32-year-old female of Wolff-Parkinson-White (WPW) syndrome associated with mitral stenosis because of several episodes of syncopal attacks and a possibility of hemodynamic deterioration following tachyarrhythmia. A presence of bundle of Kent was suggested by preoperative pacing study, while an epicardial mapping revealed that the earliest point of premature ventricular activation was at the right ventricle near the atrioventricular sulcus. Following a transverse cut on the endocardial surface of the right atrium close to the A-V ring, the delta waves disappeared. Postoperative epicardial mapping revealed that the apex of the right ventricle was the earliest activated site. Open mitral commissurotomy was performed thereafter.
Although the surgical interruption of the accessory pathway is still in experimental stage, the surgical treatment should be considered when WPW syndrome is associated with disabling tachyarrhythmias resistant to medical treatment or mitral valvular disease requiring operative intervention.
