Intravenous digital subtraction angiography. Collateral circulation to 'empty leg'.

Among 60 patients with uni- or bilateral occlusion of the common or external iliac arteries or both, 12 patients had collateral blood supply originating from the internal mammary or lateral thoracic arteries, or both. By means of intravenous digital subtraction angiography the thoracic arterial pathways and the non-occluded arteries of both legs, simultaneously, were easily demonstrated using the 30 cm effective field size of a Sirecon 33 triplex N image intensifier.

Erosive gastritis.

Erosive gastritis is a well-defined radiologic and endoscopic entity. It is one of the common causes of upper gastrointestinal bleeding, yet it is seldom diagnosed and often confused with a number of other diseases. This communication re-emphasizes the characteristic endoscopic and radiologic features of erosive gastritis and its differential diagnosis. Two representative cases are reported.

Accidents among schizophrenic outpatients.

A preliminary comparison of traffic, home, and work accident incidence was performed among 103 outpatient schizophrenic patients and an age matched sample of 123 controls. The number of motor vehicle drivers among schizophrenic outpatients was far less than among controls (70 of 103 versus 122 of 123; P = .00001). Among those who did drive, schizophrenic patients drove far less than controls (19 of 70 patients driving greater than or equal to 5,000 miles per year versus 81 of 122 controls; P = .0001). Patients also reported more accidents per miles driven than did controls, consistent with previous studies. Older patients reported more home accidents than did younger patients (five of eight for those over 55 years versus four of 95 for those less than 55; P = .0007); no similar effect was observed among controls. Schizophrenic outpatients may be at greater risk of motor vehicle accidents per miles driven than age matched controls; elderly patients may be at higher risk of home accidents as well.

Sex-linked pattern of collaterals in iliac artery occlusive disease.

Aorto-femoral angiography carried out in 839 patients revealed that 139 males and females had uni- or bilateral occlusion of the common or external iliac arteries. Pelvic or lumbar/intercostal arteries served as collaterals in 786 patients. In the remaining 53 patients the collateral blood supply originated from the thoracic arteries. Among the 53 patients, only 7 were females. A chi 2-test revealed the difference to be significant (p less than 0.0005), indicating a sex-linked difference, a male preponderance, in the development of collateral circulation of thoracic origin.

[The occurrence of a reovirus variant in a German broiler flock].

Broilers deriving from a parent flock, which had been effected in the 6th. month of hatching egg production, show arthritis beginning with the 12th day of life. The tarso-metatarsal joint has been affected. Birds show stunting. Body weights at slaughter and feed conversion of the affected flocks were reduced. The percentage of condemned birds before slaughter was highly increase and came up to 3-5%. Chickens of other breeder flocks, which were reared with the diseased birds, showed viral arthritis at an age of 18-20th day of life. The boilers derived from parent flocks which had been vaccinated twice during the with a 1133 reo live vaccine and before laying with an oil based vaccine of the antigen type WVU. A reovirus has been isolated (isolate K 171/87), which caused viral arthritis in 1133-immune day old chicks after parenteral and oral application. Infection of these chickens with the pathogenic reovirus of the antigen type 1133 didn't cause a disease. Also by serological examinations it was shown, that the reo-isolate K 171/87 possesses a different antigenicity. The kind of occurrence indicates, that this reovirus infection has been transmitted vertically from one parent flock and it spread laterally to chickens of other parent flocks in broiler farms.
