A space-occupying lesion in the liver due to Capillaria infection.

A space-occupying lesion 3.5 by 2.0 cm in size caused by Capillaria infection was revealed ultrasonographically in segment 6 (S6) of the liver of a 32-year-old woman from Okinawa, Japan, who was hospitalized with a complaint of pain in the right upper quadrant. Laboratory examination showed leukocytosis of 10,400/mm3 with 22% eosinophils and slight impairment of liver function. The tumor was removed surgically and found to be a necrotic granuloma with eosinophilic infiltration formed around a degenerated nematode. The causative agent was presumed to be Capillaria hepatica based on the morphology of the bacillary bands and stichosome observed in the sectioned worm and in the fragments of worm recovered by dissecting the tumor tissue that was embedded in paraffin.

Five-year clinical evaluation of the St. Jude Medical valve prosthesis in 136 patients.

One hundred and thirty-six patients (June 1979, through May 1984) underwent mitral, aortic or double valve replacement and apico-aortic bypass with the St. Jude Medical (SJM) prosthesis, at Ryukyu University Hospital, Okinawa. Operative mortality for the entire group was 4.4 per cent. Late mortality from 1979-1984 was 6.1 per cent. There were no deaths related to mechanical failure. Warfarin anticoagulation was recommended for all patients. The incidence of thromboembolism was 0.76/100 patient years. Post operative catheterization studies in 21 patients one year after operation showed a satisfactory recovery of cardiac function. The SJM valve seems to be the satisfactory artificial valve in present use.

Sternal dehiscence: "delayed primary closure" for complicated cases.

"Delayed primary closure" of the wound in cases of sternal dehiscence is reported. This technique includes a thorough debridement, continuous antibiotic lavage, and air tight force suction of the debrided space, using a portable wound suction unit. Healing process of the complicated sternal dehiscence is thus facilitated. A discussion is made of reasons for failure and missed chances in "early primary closure" of the sternal dehiscence.

Effect of allopurinol (zyloric) on patients undergoing open heart surgery.

We observed previously that allopurinol, which was used for the treatment of gout, had a life saving effect after experiment on traumatic shock rats and hemorrhagic shock rabbits. To evaluate the effect of allopurinol fifteen patients undergoing open heart surgery who were considered to have similar metabolic derangement in shock patient were examined. Allopurinol was given orally 2 mg per kg body weight twice before the start of nitrous oxide, oxygen and halothane anesthesia. In the control group of ten patients who were not treated with allopurinol, serum uric acid increased, the lactate/pyruvate ratio rose and beta-glucuronidase activity increased respectively after open heart surgery as in shock. But the metabolic changes of the fifteen patients pretreated with allopurinol were less significant, although same tendency was observed. The heart beat of all patients except one case in the allopurinol group, started spontaneously after extracorporeal circulation without using DC counter shock. In the control group all patients needed DC counter shock. We concluded that allopurinol was effective in preventing damage of cellular structures and derangements of metabolism of patients undergoing open heart surgery.
