摘要:

ABSTRACTBetween 1954 and 1984, 102 cases of carcinoma of the penis were seen at the Peter MacCallum Cancer Institute. Their mean age was 62.5 years. Nearly twice as many patients were referred in the last decade as in the first, and this observation may be linked to the reduction in numbers of neonatal circumcisions in the last forty years. The material reported is selected by referral patterns of recurrence following surgery elsewhere or the patient's preference for conservative management. As a result the overall survival figures have little meaning. However it is apparent that where possible and where acceptable, partial surgical amputation is more likely to achieve local cure and to be less disturbing for patients with invasive disease. Radiotherapy can be effective in controlling superficial primaries and may be curative in early, or rarely in late, stage nodal disease. Prevention by circumcision in infancy is still the best policy.

摘要:

SUMMARYThirteen young patients with DST are presented. The average age was 31.3 years. Seven patients presented with severe headaches. Six patients appeared to have no apparent cause for their thromboses while predisposing factors (polycythaemia, malignancy, posttrauma), were present in three. One patient was in her 1st trimester of pregnancy. Four patients had DVT while 2 of these patients also had pulmonary embolism. There was one death. Six patients had full recovery and six had mild residual hemiparesis. The prognosis is therefore good in this group of young patients with DST. Treatment should be directed at the primary cause. Where no cause can be found, treatment is aimed at the presenting symptoms.The role of CT is stressed. The presence of abnormal areas of hemorrhage or infarctions especially if they are parasagittal and/or bilateral should alert the radiologist to the diagnosis of DST. The empty delta sign, the cord sign, the dense vein sign as well as the presence of transcerebral medullary veins are highly specific. CT is therefore not only noninvasive but highly accurate and is the imaging procedure of choice. There is no need for angiography except in a selected few and CT has already replaced angiography. The role of MRI needs to be studied. It is entirely noninvasive and may when it becomes freely available, replace CT. So far, only three cases have been reported in the English literature. Signal void is a characteristic of flowing blood and a throm‐bosed venous channel will show a shortening of the T1 signals. In addition, the paramagnetic properties of deoxyhaemoglobin and methaemoglobin may allow determination of the age of the thrombus (Macchiet al1986). However, at the present state of the art, CT remains the first radiological screening procedure (Braunet al1985

摘要:

ABSTRACTA total of 367 patients were studied using Hexabrix 320 as intravenous contrast material during CT scanning. Adverse events were recorded and analysed with respect to patient age and risk category. Hexabrix 320 produced adequate image quality in all patients. Whilst minor adverse events were relatively common, only a few moderate adverse events were seen and no severe adverse events were observed. Hexabrix 320 was noted to be very well tolerated in the elderly and well tolerated by the high risk patient.

摘要:

SUMMARY AND CONCLUSIONSIn this controlled randomised double‐blind parallel group study of the use of ioversol‐240 and ioversol‐320 in venography all studies were considered diagnostic with comparable quality in the two groups.Patient tolerance was high with mild heat observed in 7 patients in the ioversot‐320 group and 1 patient in the ioversol‐240 group. Assessment of pain was also comparable (2 patients in the ioversol‐240 group and 1 in the ioversol‐320 group).Both strengths of the contrast agent produced no clinically significant, drug related, changes in vital signs or laboratory parameters and there were no significant clinical adve
