Dispersal of 10-14-mesh corncob granules in stacked tires.

Dispersal of 10-14-mesh corncob granules was evaluated in 2 random-stacked tire piles, one shingle-stacked tire pile, and one column-stacked tire pile located in a used-tire storage facility in Chicago, IL. Ninety percent and 98%, respectively, of the tires in the 2 random-stacked piles contained granules. In the shingle-stacked tire pile 87% of the tires sampled contained granules, and the number of granules per tire was dependent on depth.

Mosquito productivity and surveillance for St. Louis encephalitis virus in Chicago during 1993.

The City of Chicago's Department of Health monitors weekly deposition of egg rafts of Culex species, prevalence of St. Louis encephalitis (SLE) virus-specific antibodies in feral birds, and prevalence of the virus in mosquito pools. The total number of Culex egg rafts collected in 1993 (4,623) was 2-fold greater than for the 1992 mosquito season.

Penetration rate of two pesticide carriers at a large used-tire storage facility in Chicago, Illinois.

During August 1987, a large and concentrated infestation of Aedes albopictus was discovered on the property of a tire recapper and gasket manufacturer in Chicago, IL, in a densely populated urban environment. The infestation called for special abatement procedures because of the large number of tires and the varied ways they were stacked. An effective method for delivering pesticides into the cavity of each tire is described.

[Surgically treated esophageal perforation caused by metal esophagoscope].

A case of oesophageal perforation is described occurring during oesophagoscopy carried out in search for a foreign body. After several hours of observation the hole in the oesophagus was closed with sutures. The postoperative course was complicated with posterior mediastinitis and suture failure.

[Malignant lymphoma of the stomach].

In the reported case the radiological diagnosis before the operation was--malignant tumour of the stomach. Nearly complete gastrectomy by the Roux-en-Y method was done. In the histological examination malignant lymphoma was diagnosed.

[Superficial femoral artery aneurysm with imminent rupture].

A case of aneurysm of the superficial femoral artery with imminent rupture was treated surgically as an emergency with good result confirmed by control arteriography. Intraoperative and postoperative radiological investigation demonstrated aneurysmatic dilatation of both superficial femoral arteries.

Management of the posterior peritoneum after transperitoneal renal surgery.

Between 1977 and 1982, 15 patients underwent renal operations carried out transperitoneally and in none was the posterior peritoneum reconstituted. There were no significant complications.
