High copper, cadmium and lead decreased iron absorption and negatively affected hematological parameters.

Children with TM are posed with an increased risk of psychopathology.

The basal cortisol level and cortisol response to ACTH stimulation test were assessed in patients with sepsis, the results being compared to a control group of 30 healthy persons. The study group included 49 patients with sepsis and 30 healthy subjects as a control group. The mean age in the study group was 42.6 +/- 18.7 years and 41.4 +/- 12.1 years in the control group. Fifteen of the 49 (30.6%) patients had hospital-acquired and 34 (69.4%) patients community-acquired sepsis. Etiological agent was isolated in 35 (71.4%) patients (57.1% gram negative bacteria and 34.3% gram positive bacteria, plus 8.6% polymicrobial). Fourteen of 49 (28.6%) patients died. Mean basal cortisol level was 597.1 +/- 304.6 nmol/l (range 217.8-1667.9) in the study group and 460.2 +/- 180.8 nmol/l (range 253.6-988.9) in the control group. Mean basal cortisol level in the study group was significantly higher than that of the control group (p < 0.05). Mean basal cortisol level was found to be 725.5 +/- 448.9 nmol/l in the patients who died and 545.8 +/- 210.9 nmol/l in the patients who recovered. The difference between the two groups was found to be significant (p < 0.05). ACTH stimulation test was performed in 43 of the patients and 30 healthy subjects. Cortisol response was significantly lower (mean 277.7 +/- 216.9 nmol/l) in the patients than that detected in the control group (mean 519.6 +/- 279.2) (p < 0.001). Mean cortisol response in the patients who died was 227.2 +/- 224.5 nmol/l and 302.1 +/- 212.7 nmol/l in the patients who recovered (p > 0.05). Adrenocortical insufficiency was detected in 16.3% of the patients and 42.9% of these patients died. In conclusion, sepsis is characterized by high basal cortisol level which may show a poor prognosis and a blunted cortisol response to ACTH stimulation. A small percentage of patients with sepsis may develop adrenocortical insufficiency.

Thyroid hormone supplementation in septic rats had a beneficial effect on the sepsis criteria and also resulted in a lower rate of mortality.

Endotoxaemia in obstructive jaundice may induce overproduction of nitric oxide that may lead to impairment of cGMP-associated vasodilatation and disrupt autoregulation of the renal vascular bed. This may contribute to renal failure in obstructive jaundice.
