Urodynamic study showed that phenoxy-benzamine improves the urination of patient with benign prostatic hypertrophy. Relative voiding resistance was introduced in this study as an over-all parameter for evaluating the efficiency of urination. As an over-all parameter it is more convenient than the maximum flow rate which is not valid when the urinary volume is below 200 ml.

The suspension of an aromatic iodocompound (TABAC) was prepared and infused iv into 21 monkeys and 5 men. The hepatograms were dense and the contrast remained long enough for tomography. This technic is capable of demonstrating space-occupying lesions as small as about 1 cm in diameter in man. The side effects are acceptable compared with other invasive hepatographic methods.

From April 1973 to March 1981, 400 corrective operations were performed on 394 patients with tetralogy of Fallot. The right ventricular outflow tract was patched in 109, valved conduit graft inserted between the right ventricle and pulmonary artery in 5 and 6 were reoperated upon to close residual ventricular septal defect. Operative mortality was 3.8% and late mortality 2.9%. To improve corrective surgery results indications for surgery should be appropriate, criteria for the surgical procedure and improvement of the technic, improvement of perfusion technic and cardiac protection and intensified management of postoperative low cardiac output syndrome are necessary.

The basic therapeutic principles in traumatic shock include removing the life-threatening cause and maintaining a patent airway; rapid restoration of adequate circulating blood volume, correction of acidosis; proper use of vasoprcssors or vasodilators; preservation of renal function; cardiotonics and/or corticosteroids and supplementary oxygen and intensive care.

From 1957 to 1979, 81 cases of nonunion of forearm fracture were treated. Among them 36 had ulnar, 24 radial and 21 radioulnar fractures. The average duration of injury was 17.1 months. The main factors causing nonunion were severe original fracture therapeutic faults and bone infections. Treatment consisted of rigid internal fixation and grafting with sufficient cancellous bones. 96% of the cases were cured by one operation and 3 failed owing to infection. 50 cases were followed up for an average of 12.7 months, 78% of them obtained excellent and good functional results. The recovery of supination was better than that of pronation.

Channel and collateral sensation may occur spontaneously with cerebral diseases. When these sensations are symptoms of intracranial disease, they manifest as epilepsy. This based not only upon the clinical features but also upon the effect of dilantin on the fit. The author names this sort of symptomatic seizure epilepsy of channel sensory attack type.

Since May 1972, the authors have used the saphenous vein as autograft for reconstruction of wrist blood circulation in treating 15 cases of electrically burned upper limbs with wrist vascular injuries. Using this method in 11 limbs, necrosis was avoided. Pathologic study was done after early stage treatment of the injured arteries. Also observed pathologically were the arteries of the limbs amputated after conservative treatment. These studies suggest a pathologic concept of the damage induced by electric current passing through the upper limbs, revealing the mechanism of t.he injury and providing a basis for early vascular reconstruction to prevent necrosis.

19 cases of Tourette syndrome are reported. The clinical features including initial symptoms, distribution of abnormal movements, vocal phenomena, mental condition, neurologic examinations, EEG, and laboratory examinations are described. Haloperidol is again proved in our series to be the most effective drug in the syndrome. In 1 severe, obstinate case resistant to haloperidol, combined haloperidol with nitrazepam yielded most satisfactory results. Clonidine and imipramine have also been tried with some effect. The theraDeutic effect of haloperidol and the high homovanillic acid level in the cerebrospinal fluid in this series support the hypothesis of dopaminergic hyperactivity in the syndrome.

This is a report of 2,530 cases of hospitalized pediatric arrhythmia patients. There were 793 ectopic arrhythmias with conductrive disturbances accounting for 23.7% of all 3,351 electro-cardiograms made during the same period, indicating that arrhythmia is common in hospitalized children. The common types of pediatric arrhythmia are A-V block, premature beats of ventricular and supraventricular origin, incomplete right bundle branch block and paroxysmal supraventricular tachycardia The common causes of pediatric arrhythmia are infectious toxic myocarditis, theumatic fever, theumatic heart disease and digitalis intoxication, indicating a close correlation between infection and the development of pediatric arrhythmia. So management of infectious diseases plays an important role in the prevention and treatment of the disease. The prognosis is generally good with a death rate of only about 1%. Arrhythmias disappear following control of the primary disease.

93 different types of carries were studied to determine the probability of carriership. The methods of calculating pedigree probability, likelihood ratio and final probability (FP) are described. FP is 1 in 31 obligate carriers, 0.9015-0.9999 in 7 probable carriers and 70.5-0.9999 in 7 of 55 possible carriers. The authors believe that carrier detection is paramount in genetic counselling.
