The prevalence of varicocele is 7% and 10–25% in pre pubertal and post pubertal males, respectively [1]. Varicoceles are found in 21–41% of men with primary infertility and 75–81% of those with secondary infertility. Physical examination of varicocele has a sensitivity and specificity of around 70%. The Color Doppler ultrasound (7MHz) has sensitivity of 50% and specificity of 90%. A pencil prob...

Definitive acid-reducing peptic ulcer surgery currently plays a less prominent role than medical treatment in the management of peptic ulceration. The utilisation of proton pump inhibitors and Helicobacter eradication are proven effective therapies. Giant duodenal ulcers, first described by Brdiczka in 1931, 3 pose a unique challenge to this shift in therapy. There are various described surgica...

(1875–1961) dedicated himself to his work as a professor of surgery at Severance Union Medical College. During his travels with L. H. Severance to Korea in 1907 (Fig. 1), Dr. Ludlow attended the meeting of the 15th Presbyterian Council and the First Presbytery of the Presbyterian in Ko-rea and decided to become a medical missionary at the age of 37. By 1912, he had devoted his life to Severance...

coimplantation with a MtT or by daily administration of the tranquilizing drug, perphenazine (4-[3-(2-chborophenothiazin 10-yI)propyl]-1 -piperazineethanol) (6). MTW9-MtT is grown by coimplantation of MTW9 with MtTW10, a MtT which secretes prolactin, growth hormone, and probably ACTH (5). MTW9-MtT stops growing after ovaniec tomy but does not regress; regression occurs after surgical removal of...

The effect of supradiaphragmatic splanchnicectomy on the blood pressure of 294 hypertensive patients followed for 10 to 18 months after surgery is compared with the effects of nonspecific medical management in a control group of 79 patients similarly studied. The data are presented in simple graphic form. It is concluded that 29 per cent of the hypertensive patients had reductions in blood pres...

A case is presented in which a complete left atrial myxoma became detached and lodged in the aortic bifurcation. Shortly after it had been removed the patient suffered cardiac arrest and could not be revived. The occurrence of saddle embolism of the aorta resulting from total expulsion of a left atrial myxoma is rare. Only five previous cases have been recorded. Three of them died-one without s...

Within 5 hours after administration of cortico-steroids to experimental animals, the activity of hepatic tyrosine-a-ketoglutarate transaminase is increased five-to tenfold (1-8). This enzyme cata-lyzes the initial step in tyrosine degradation and is one of several mammalian enzymes the activity of which is rapidly and substantially elevated by corticosteroids (9). Adrenal steroids also depress ...

A report is presented of nine patients who underwent early open mitral valve surgery after arterial embolism had occurred. Five of these patients suffered an early second arterial embolism before their mitral operation, an observation which stresses the risk inherent in delay of mitral valve surgery. The demonstration of atrial thrombi in four illustrates the potential danger of closed valvotom...

When we started to plan this special issue, we were under the thought that we are facing more and more cases of small renal masses in our daily work as urologists and pathologists. This common fact nowadays will probably increase in the near future as radiological studies are more frequently ordered and fortunately we face an increase in longevity, and also as people can get to detect their ren...
