Fatal air embolism following gunshot wound of the lung

Air embolism following penetrating lung trauma has been reported infrequently and its existence is questioned. A death resulting from air embolism following a high-velocity gunshot wound is presented. Appropriate treatment and preventive measures are discussed.     

The prognostic factors of arterialized bypass veins in the lower extremities

Two children with cystitis presented with multiple filling defects in the urinary bladder. They were proven to be cases of cystitis glandularis with proliferative changes of the bladder epithelium. The radiographic findings are described and the differential diagnosis from neoplasms is outlined.     

Rare diseases of the abdominal organs simulating malignant tumors

The results of local cerebral blood flow examinations were analysed in 20 patients in the postoperative period. The dynamics of the restoration of the vascular responses to functional tests was observed. A study of the changes of the local cerebral blood flow following the administration of Rheopolyglukin demonstrated its high efficacy. The rationale of a combined employment of dehydration drugs and agents improving the rheological properties of blood is emphasized.     

End-stage liver disease without hemochromatosis associated with elevated hepatic iron index

Erythromycin resistance among streptococci is commonly due to target site modification by an rRNA-methylating enzyme, which results in coresistance to macrolide, lincosamide, and streptogramin B antibiotics (MLSB resistance). Genes belonging to the ermAM (ermB) gene class are the only erythromycin resistance methylase (erm) genes in Streptococcus pyogenes with MLSB resistance that have been sequenced so far. We identified a novel erm gene, designated ermTR, from an erythromycin-resistant clinical strain of S. pyogenes (strain A200) with an inducible type of MLSB resistance. The nucleotide sequence of ermTR is 82.5% identical to ermA, previously found, for example, in Staphylococcus aureus and coagulase-negative staphylococci. Our finding provides the first sequence of an erm gene other than ermAM that mediates MLSB resistance in S. pyogenes.
