Soft tissue chondrosarcoma of the back--a case report.

A case of extraosseous chondrosarcoma arising from the soft tissues of the back is presented. The tumour was completely excised with a wide margin of normal tissues. Extraosseous chondrosarcoma arising from the soft tissues of the back has apparently never been reported.

Myoelectrical activity in experimental aganglionosis of the colon in the rat.

Experimental aganglionosis of the colon was produced in rats by an experimental "aganglionosis producing" procedure. Radiological examination of the aganglionic colon showed a narrow segment distal to a dilated megacolon. Histologically, a transverse section of the aganglionic segment showed 3-4 ganglia in contrast to 32-40 ganglia per section in the normal colon. The myoelectrical activity of the normal colon presented two fast activities, a fast activity with a frequency of 25-40 cycles per sec superimposed over a medium-fast activity of 4-7 cycles per sec. However the aganglionic colon showed only the fast activity with complete absence of the medium-fast activity. Thus the experimental aganglionosis produced a characteristic alteration in the myoelectrical activity of colon. This confirms our earlier findings in children with Hirschsprung's disease. It also suggests that the causative mechanism for the production of a narrow segment in Hirschsprung's disease may not be the hyperactivity or the absence of any specific neuronal mechanisms as proposed earlier.

Treatment of carotid cavernous fistula by intravascular occlusion using a balloon catheter.

The surgical treatment of carotid cavernous fistula gradually evolved into a "trapping" technique. This technique includes ligation of the cervical internal carotid artery, clipping of the intracranial portion distal to the fistula and often embolization of the isolated segment. The development of embolization techniques using intravascular balloon catheters greatly simplified this treatment. The authors report a case of spontaneous carotid cavernous fistula in which obliteration was achieved by an intracarotid balloon catheter. This was inserted by direct puncture of the carotid artery, which had been exposed by a simple neck incision. The patient's visual acuity was preserved. The efficacy, ease and safety of this method are emphasized.

Rupture of the diaphragm resulting from blunt trauma in children.

Rupture of the diaphragm due to blunt trauma is rare in the pediatric age group. This article describes six such cases. This life-threatening condition should be suspected in the case of any serious thoracoabdominal trauma, even in the presence of negative radiographic findings on initial evaluation. In the very sick child, horizontal beam, lateral radiographs of the chest and abdomen have been extremely useful in establishing the diagnosis. The suspicion and investigation of associated diaphragmatic injury will result in earlier diagnosis and treatment.

Primary carcinoma of the gallbladder.

The clinical and pathological features of 100 consecutive cases of primary carcinoma of the gallbladder, treated by a single surgical unit, are described. Females out numbered males by 2 to 1. The maximum incidence was seen in the fifth decade. Pain and the presence of a mass were the two most common clinical features. Gallstones coexisted in 45 per cent of cases. Ancillary investigations were of little value in preoperative diagnosis. At laparotomy biopsy alone was possible in a large number of cases owing to the advanced disease process. Two patients were alive 5 years after surgery. Prophylactic cholecystectomy for all diseased gallbladders, whether symptomatic or not, is advocated.
