Effect of myocardial infarction on components of fibrinolytic system.
A systematic investigation of the fibrinolytic system during the period after acute myocardial infarction in 42 patients showed a progressive reduction of fibrinolytic activity, with the longest lysis times on days 4 to 5 after the event. There is a concomitant rise in the levels of fibrinogen, plasminogen, and antiplasmin; only the latter parallels the delay in lysis. After 12 to 15 months, normal lysis times and fibrinogen levels were found in 24 patients re-examined. It is concluded that the reduced fibrinolytic activity in these patients was a transient phenomenon after myocardial infarction.

The role of pleural fluid-serum gradient of tumor necrosis factor-alpha concentration in discrimination between complicated and uncomplicated parapneumonic effusion.
In a previous preliminary study an excess of tumor necrosis factor-alpha (TNF) was found in pleural fluid of patients with complicated parapneumonic effusion (CPPE), and its levels in pleural fluid of these patients were shown to be significantly higher than those in patients with uncomplicated parapneumonic effusion (UCPPE). This larger population study was undertaken to investigate, for the first time, the role of pleural fluid-serum gradient of TNF (TNFgradient) in discrimination between UCPPE and CPPE. Using a commercially available high sensitivity ELISA kit, levels of TNF were measured in serum and pleural fluid of 51 patients with UCPPE and 30 patients with nonempyemic CPPE. The mean +/- SEM values of serum TNF (TNFserum), pleural fluid TNF (TNFpf), and TNFgradient in the UCPPE group were 6.65 +/- 0.48 pg/mL, 10.85 +/- 0.74 pg/mL, and 4.2 +/- 0.38 pg/mL respectively, and in the CPPE group they were 7.59 +/- 0.87 pg/mL, 54.02 +/- 5.43 pg/mL, and 46.43 +/- 5.34 pg/mL, respectively. While no significant difference was found between the two groups regarding levels of TNFserum (p = 0.31), a highly significant difference between these two groups was found regarding levels of TNFpf and TNFgradient (p < 0.0001 for both variables). A significant correlation was found between levels of TNFserum and levels of TNFpf in the UCPPE group (r = 0.89, p < 0.0001), but not in the CPPE group (r = 0.18, p < 0.33). TNFgradient at an optimal cut-off level of 9.0 pg/mL was found to be a good marker for discrimination between UCPPE and CPPE (sensitivity, 96.7%, specificity, 98%, accuracy, 97.5%, and p < 0.0001). In conclusion, levels of TNFpf but not TNFserum are significantly higher in CPPEs than those in UCPPEs where TNFgradient at an optimal cut-off level of 9.0 pg/mL is a good marker for discrimination between UCPPE and CPPE.

Pyomyositis of the thigh due to Prevotella melaninogenica.
Pyomyositis is an uncommon infection in temperate climates, however, it is being more frequently reported among patients with diabetes or malignancy, or those who are immunocompromised. It is predominantly caused by Staphylococcus aureus, and rarely by Bacteroides species. Pyomyositis due to Prevotella melaninogenica has not previously been reported. We describe an elderly patient with pyomyositis of the thigh due to P. melaninogenica which was successfully treated by surgical incision and drainage in combination with metronidazole therapy.

Acute pancreatitis associated with brucellosis.
Acute pancreatitis developed in a patient with acute brucellosis due to Brucella melitensis. To the best of our knowledge this is only the second reported case of acute pancreatitis associated with Brucella infection.

Gastrointestinal enhanced insulin release in response to glucose in newborn infants.
The purpose of this investigation was to determine whether or not gastrointestinal (GI) enhanced insulin response occurs in newborn infants soon after birth. Glucose infusion by intravenous or orogastric routes was given to infants during the first 4 days of life, aiming at achieving similar plasma glucose concentrations. Their plasma insulin responses were then compared. Thirty term, newborn infants (10 appropriate for gestational age, 8 small for gestational age, 6 large for gestational age, and 6 infants of diabetic mothers) were studied. With intravenous glucose infusions of 8 mg/kg/min or orogastric infusion of 16 mg/kg/min, the plasma glucose concentrations achieved were similar and approximated 110 mg/dl. Plasma insulin responses were greater in infants receiving glucose via the GI route. The finding was in contrast to our previous data, in which no GI enhancement of insulin response was demonstrated. The present data suggest that in the term newborn infant, GI enhanced insulin release occurs only when a threshold of plasma glucose concentration has been exceeded. It appears that the enteroinsular axis is functional in newborns soon after birth.
