Is screening for abdominal aortic aneurysm worthwhile?

A calculation is made of the cost for an ultrasound screening programme for abdominal aortic aneurysm. From this is derived the cost of a QALY (Quality Adjusted Life Year) for different ages and sex. The cost of a QALY in this programme compares well with other types of screening programme. It is found that a screening programme should include both men and women.

Medico-legal aspects of cross infection: dental scenario.

The epidemiology of Hepatitis B infection is used to show that dental health care workers are at greater risk of acquiring serious infective diseases than is the population at large. The significance of this greater risk is that dental employers must take the proper steps to protect their employees' health. A five fold strategy is put forward to achieve this end. The law governing a (dental) employer's duty in this regard is examined. Failure to take appropriate action leaves the dental employer open to legal action in the event that an employee acquires a serious infection in the course of his work. The similarity is stressed between Irish and British law in protecting the needs of authority and established bodies such as for instance the dental profession. However, the developments in Irish law are mentioned which show that following established practice in a profession does not guarantee protection from legal suit.

A clinical evaluation of isotope scanning, ultrasonography and computed tomography in pancreatic disease.

In a prospective study of 46 patients with suspected pancreatic disease the provisional diagnoses arrived at independently by isotope scanning (IS), ultrasonography (USS) and computed tomography (CT) have been compared. In the control group, IS and CT were associated with a higher false positive rate than USS; The isotope scan was abnormal in most patients with proven chronic pancreatitis and cancer. The results from USS and CT were similar when structural changes were present. USS was superior in diagnosing pancreatic carcinoma and was a convenient means to follow the progression of acute pancreatitis to final resolution or the development of a pseudocyst. CT proved especially useful in accurately delineating cysts, pseudocysts and calculi prior to planning surgery and in assessing disease in contiguous viscera.

Ultrasonic scanning in pancreatic disease.

We have analysed retrospectively the pancreatic ultrasound scans (using a bistable machine) in 138 consecutive patients, and have related the results to the clinical status and the final diagnosis in each case. The scans were read without knowledge of the patient's clinical state. When technically unsatisfactory scans were excluded from consideration, the overall diagnostic accuracy of ultrasonography proved to be 82%, with a false positive rate of 8%. The scan was abnormal in all 10 patients with cancer of the pancreas: a positive diagnosis of cancer was made in six. All patients with chronic pancreatitis in relapse had abnormal scans, but in 53% the scans were normal in patients in whom the disease was in clinical remission. In seven patients with chronic pancreatitis who suffered relentless pain, the head of the pancreas was swollen and contained cystic areas or emitted abnormal echoes. In acute pancreatitis ultrasonic scanning proved useful in following the progression of the disease to final resolution, or to development of complicating pseudocyst, abscess, or ascites. Random echoes in the early stages of acute pancreatitis are features of haemorrhagic necrosis. In alcoholic relapsing pancreatitis the persistence of abnormal echoes, disposed linearly along the axis of major ducts, suggests the presence of chronic pancreatitis.

Single dose of two grams of metronidazole for Trichomonas vaginalis infection.

In this study, 243 women with symptomatic trichomonal vaginitis were treated with eight 250 mg. tablets of metronidazole for themselves, and eight tablets were given to each of their male consorts. They were given instructions to ingest "all eight in a row" and "avoid alcohol for 48 hours." Ninety-five per cent of 203 women that returned for re-examination were cured. This single-dose treatment is effective, well tolerated, and less expensive than current recommended dosages.

Longitudinal angulation in coronary arteriography: apparatus and evaluation.

When good visualization of the left coronary artery and proximal branches is difficult, the longitudinally angulated projection has proved useful. An accessory for achieving this angulation with a conventional angiographic table and without sacrificing the advantages of video monitoring and the protection of lead vinyl shielding is described.

Radiology of acalculous gall-bladder disease - a new sign.

Radiography of excised gall-bladders, immersed in water, has shown that chronically infected gall-bladders frequently contain fat. This fat can be seen in vivo, and the frequency of the finding was assessed by reviewing 43 patients with acalculous gall-bladder disease. Other radiological signs in the cholecystograms were looked for retrospectively, and their incidence assessed. In 20 cases out of 40, no radiological abnormality was found.
