Paraesophageal hernia repair followed by cardiac tamponade caused by ProTacks.

We describe a case of cardiac tamponade caused by ProTacks Autosuture used for mesh fixation during a laparoscopic Nissen operation with giant paraesophageal hernia repair. Perforations of the posterior descendent artery and epicardial vein of the right ventricle were caused by ProTacks used for Parietex Composite Mesh fixation. Protruding ProTacks were secured from inside the pericardiac sac with a synthetic vascular patch during emergency sternotomy.

Human stored blood inositol phospholipids.

The total amount of phospholipids of the stored blood erythrocytes does not change during the first week of storage. After the second and the third week of storage the changes are only insignificant. During the fourth week this amount decreases by 25%.

Phospholipid composition of plasma and erythrocytes in the neonate.

The total phospholipids and their various classes in erythrocytes and blood plasma were determined quantitatively by means of two-dimensional thin-layer chromatography. The total amount of phospholipids in neonate plasma was approximately half of that found in adult plasma, however, the amount of phospholipids in erythrocytes of the neonate was significantly higher. The differences were observed in some classes of phospholipids in the plasma and erythrocytes of neonates as well as adult human beings.

Turnover of phosphomonoester groups and compartmentation of polyphosphoinositides in human erythrocytes.

The turnover of phosphomonoester groups of phosphatidylinositol 4-phosphate (PtdIns4P) and phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2] was investigated in human erythrocytes by short-term labelling with [32P]Pi. The procedure applied ensured a quantitative extraction of erythrocyte polyphosphoinositides as well as their reliable separation for the determinations of pool sizes and specific radioactivities. The pool sizes of phosphatidylinositol (PtdIns), PtdIns4P and PtdIns(4,5)P2 are 25, 11 and 44 nmol/ml of cells respectively.

Composition of phospholipids in various rat tissues.

Total phospholipids and their various classes in erythrocytes, the blood plasma, liver, lung, myocardium, spleen and skeletal muscles were determined quantitatively by means of two-dimensional thin-layer chromatography.
