BACKGROUND: The circadian cycle of the endogenous anti-inflammatory system (EAIS) is characterized by a morning increase in cortisol production. Circulating interleukin-6 (IL-6) activates the EAIS. A circadian variation in the onset of myocardial infarction, sudden death, stable angina (SA) and unstable angina (UA) has been reported. The aim of this study was to determine morning cortisol production in coronary heart disease (CHD) patients. MATERIALS AND METHODS: Serum cortisol and IL-6 were measured in 129 patients with either SA (n = 65) or UA (n = 64) and 40 healthy volunteers. Blood samples were taken between 9 : 00 h and 12 : 00 h. The upper normal range of cortisol (25 microg dL-1) was used as a reference to classify patients. RESULTS: Forty-eight patients had elevated cortisol levels (ECL) (32.5 +/- 5.4 microg dL-1), while 81 patients had normal cortisol levels (NCL) (15.7 +/- 5.9 microg dL-1). In NCL patients, IL-6 levels (26.6 pg mL-1, ranged from 0.2 to 183.7) were significantly higher (P < 0.004) than in ECL patients (9.70 pg mL-1, range 0.07-56.5). Forty-eight patients with UA belonged to the NCL group of patients, while only 16 UA patients belonged to the ECL group (chi(2) = 0.000). Thirty-two patients with SA belonged to the ECL group, and 33 to the NCL group (chi(2) = 0.08). CONCLUSIONS: Patients with 'inappropriately' normal morning cortisol production had high IL-6 levels. 'Inappropriately' normal cortisol, detected in 75% of UA and 50% of SA patients, may be insufficient for limiting inflammation. These findings have novel clinical implications and suggest new therapeutic approaches in the treatment of these patients.

Subacute stent thrombosis is currently a rare but feared complication in patients undergoing coronary intervention. Intravascular ultrasound is a useful technique to guide stent implantation. However, its value in patients suffering from acute stent thrombosis has not been described. Herein, we present the intravascular ultrasound findings of a patient experiencing ongoing stent thrombosis and impending vessel closure.

Amongst approximately 1 500 spastic children under treatment, the authors have seen three cases of fatigue fracture of the patella. One patient was spastic and two others were athetotic. The fatigue fractures can be explained by a flexed knee gait aggravated by a contracture of the hamstring tendons. No fracture was seen in patients treated by Egger's operation. It is concluded that this procedure both prevents and cures fatigue fracture of the patella.
