摘要:

ABSTRACTTwo patients with acutely throm‐bosed femorofemoral bypass grafts are presented. Recombinant human tissue‐type plasminogen activator (rt‐PA) was used successfully in thrombolysis of the occluded grafts. Utilizing a new technique the grafts were punctured directly and bolus doses of rt‐PA admin

摘要:

ABSTRACTThe sonographic parameters in portal hypertension (PHT) were examined in a consecutive population of 118 patients who had PHT diagnosed using specific endoscopic, sonographic and Doppler signs. A patent or enlarged paraumbilical vein was found in 85.6% of patients overall and 82.5% of patients with varices indicating a relatively high sensitivity. A portal vein diameter ≤ 13mm was found in only 41.1% and ≤ 15mm in only 20% of patients. A thrombosed portal vein and reversed portal vein flow were present in 3.4% and 5.3% of patients respectively. These signs have only been reported in the context of PHT and are felt to be specific for PHT, but both have a very low sensitivity.Portal vein velocities were highly variable suggesting that this is not a useful predictor of PHT. Splenomegaly was found in only 53.5% of patients demonstrating its poor sensitivity as a sign of PHT. Varices were found in 73.3% of patients overall, and in 100% of patients with a patent or enlarged paraumbilical vein combined with ascites. No other statistically significant correlation between varices and sonographic findings was demonstrated.We conclude that the presence of a patent or enlarged paraumbilical vein is a practical, useful and sensitive ultrasound sign to look for in the diagnosis of

摘要:

ABSTRACTThe diagnosis or exclusion of placenta previa is best achieved by direct visualisation of the relationship of the lower edge of the placenta to the internal cervical os. In later pregnancy, the presenting fetal part frequently obscures this area. Elevation of the presenting part was attempted in 56 consecutive pregnancies of greater than 30 weeks gestation, with a success rate of 71%. This confirms that in a minority of pregnancies, other manoeuvres or ultrasound techniques are necessary to visualke the lower placental margin directly.

摘要:

ABSTRACTFine needle lung aspiration biopsy is now a well established method of obtaining tissue for histopatho‐logical diagnosis. It is fast, simple and reliable, and has a very low complication rate. We report our experience using two fine needles, the Turner and the EZ‐EM Cut‐Biopsy needles, comparing their yield and complication rates. We found that both needles had comparable diagnostic yields (65% with the Turner, and 71% with the EZ‐EM) and complication rates. We also found that in most cases, aspirates alone were sufficient for diagnosis, and that obtaining tissue cores with larger bore EZ‐EM needles did not significantly influence the diagnostic outcome. We conclude that both the Turner and the EZ‐EM needles are equally effective and safe in percutaneous lung aspiration biopsy. The least traumatic needle should be used except when the cytological diagnosis is nonspecific inflammatory cells or inadequate, in which case a repeat with a cutting needle is advised to obtain a cor

摘要:

ABSTRACTThe aims of the study were to describe levels of discomfort experienced by women undergoing screening mammography; examine correlates of discomfort experienced and to examine whether the degree of discomfort experienced was perceived as a deterrent for re‐screening.The study involved ninety five attenders at the pilot mammography screening program in Melbourne, Victoria. Women completed a questionnaire one or two days after having a screening mammogram. Pain was assessed on a seven point scale. Information was obtained on a number of possible correlates such as breast tenderness, perceptions of the service received and expectations of discomfort. Eighty‐eight women were re‐interviewed three months later about recall of discomfort and whether this would deter them from future mammography.Results were as follows: Thirty per cent of women reported no discomfort, 60% mild or moderate discomfort and 10% severe discomfort or worse. The degree of discomfort reported was not significantly related to age, breast tenderness in the previous three days, previous symptoms, previous mammographic experience, or outcome of visit. The degree of discomfort was related to retrospectively reported expectation of discomfort (r=.336; p=.001); reported lack of confidence in the staff taking the X‐ray (r=.184; p=.039); perceptions of awkwardness (r=.175; p=.049) and unpleasantness (r=.297; p=.002) of the examination position. No woman said discomfort would definitely stop her having another screening mammogram. Three per cent said that it might stop them, while 97% of women said that it would not stop them at all.We therefore recommend that information on the possibility of discomfort be given routinely to women at the time of undergoing screening mamm

摘要:

ABSTRACTFirm breast compression during film‐screen mammography is necessary to achieve optimum image quality while minimizing radiation time. Of 374 women who fully completed a questionnaire following mammography, 225 (60%) reported no pain, 115 (31%) moderate pain and only 3 (1%) reported severe pain. Only one patient stated that the pain from the procedure would prevent her from having a further mammogram. Underlying breast disease (usually fibmystic disease) is associated with a greater incidence and severity of breast pain, but, no relationship has been demonstrated with regards to the patient's age, hormonal status, menstruation or caffeine intake. The high level of acceptance of firm compression by women in our study indicates that undue concern regarding patient discomfort should not deter people from referral for mammography or from the application of firm compressio

摘要:

ABSTRACTTwo patients with osseous hemangioma of the orbit, and with typical features on plain radiography and computed tomography, are reported. The typical features of osseous hemangioma of the orbit on computerised tomography (CT) are: expansile bony lesion limited by a thin sclerotic rim, bony trabeculae radiating from the centre to the periphery of the lesion, and absence of an associated extra‐tumoral soft tissue mass. To the best of our knowledge this is the first report of osseous hemangioma of the orbit evaluated by C

摘要:

SUMMARYAir in epidural haematoma is an uncommon finding. It is usually seen if epidural haematoma is associated with fracture involving one of the air sinuses, but can be seen at, times in the absence of any demonstrable fracture on the CT scan. Seven such cases are described in the present communication and the significance of this finding discussed.
