About the 'Omnipotence' of the Chelation Therapy In the eighties the 'method of treatment proven in many thousands of cases over 20 years' was transferred from the USA to Germany (enjoys a priori considerable faith) using very dubious promises. It was Clarke et al. who introduced this 'therapy' in 1955. The dubious promise was to maintain that the chelation therapy eliminates or alleviates symptoms in the case of the following illnesses: Alzheimer's disease, senility, schizophrenia, rheumatoid arthritis, osteoarthritis, gout, renal calculus, apoplectic coma, gallstones, multiple sclerosis, osteoporosis, chronic fatigue syndrome, varicose veins, hypertension, failure of memory, scleroderma, Raynaud's disease, digitalis intoxication, intermittent claudication, diabetic ulcer, disturbance of the blood supply, ulcer on the legs, snake poison, impotence, emotional difficulties, defective hearing, vision disorder. There is not the slightest proof of effectiveness for any of the listed indications. The burden of proof lies with the supplier. Even in the case of the relatively often examined peripheral atherosclerotic changes (claudicatio intermittens) there is no proof that EDTA has a greater effect than placebo. For coronary heart disease too there is no evidence for any usefulness of the chelation therapy beyond that of a placebo effect. Only controlled studies can help to improve the therapy in the sense of 'Evidence-based medicine'. Retrospective investigations on thousands of patients cannot 'prove' anything, although this is maintained again andagain.

An adult case of isolated fourth ventricle which developed in the early postoperative period of SAH is reported. A 72-year-old male with Hunt & Kosnik Grade 4 subarachnoid hemorrhage (SAH) underwent emergent neck-clipping of an anterior communicating artery aneurysm along with setting of external ventricular drainage (EVD) and cisternal drainage (CD). The lamina terminalis (LT) was opened. Preoperative study had showed diffuse SAH with intraventricular hemorrhage (IVH), and mild dilatation of the whole ventricular system on CT scan (Fisher Group 4). Twelve hours after surgery, both of the drainages were opened with the pressure setting of 20 cm H2O for EVD and 10 cm H2O for CD. Although his neurological state had been improving, 2 hours after the opening of the drainages he suddenly fell into respiratory arrest and coma, when 20 ml of CFS through CD was drained. On CT scan, isolated fourth ventricle was recognized. The patient died on the ninth postoperative day. In case of severe SAH with diffuse IVH, we should be careful when setting the pressure of EVD or CD with the LT opened, because of the possibility of occlusion of the fourth ventricle outlet and aqueduct, that results in fourth ventricle isolation.

Severe traumatic head injury has been recognized to be associated with hypothalamo-hypophyseal impairment and subsequent abnormalities in hormone secretion, which can contribute to a prolonged clinical course and to hampered recovery in many head-injured patients. Most of the data on the growth hormone/insulin-like growth factor -1 (GH/IGF-1) axis function have been obtained early after head injury, whereas GH secretory pattern has not been fully elucidated after patients had left the intensive care unit. We examined the activity of the GH/IGF-1 axis in 16 severely closed head-injured (CHI) patients (14 males; age range, 17 to 47 years; body mass index [BMI], 21.4 +/- 0.8 kg/m(2)) during the rehabilitation period at least 1 month after leaving the intensive care unit and in 12 sex-, age-, and weight-matched healthy controls. The severity of trauma was assessed by the Glasgow Coma Scale (GCS) score (8 or less), posttraumatic amnesia (PTA, more than 24 hours), and initial computed tomography (CT) scan. The clinical picture at time of the study was evaluated by the Rancho Los Amigos Scale of Cognitive Functioning (CFS) and the Functional Independence Measure (FIM). In all subjects, we evaluated basal levels of anterior pituitary hormones, IGF-1, insulin-like growth factor-binding protein (IGFBP)-3, and IGFBP-1, as well as the GH responses to intravenous (IV) infusion of growth hormone-releasing hormone (GHRH) alone, GHRH plus arginine (ARG), and the GH release evoked by somatostatin (SRIH) infusion withdrawal, which is related to endogenous GHRH tone. In all subjects, nutritional parameters and nitrogen balance were normal. Basal plasma concentrations of GH, IGF-1, IGFBP-3, and IGFBP-1 did not significantly differ between CHI patients and controls. The GH responses to GHRH and GHRH plus ARG did not significantly differ between CHI patients (GH peak, 10.7 +/- 3.0 microg/L; area under the curve [AUC], 5.9 +/- 1.5 microg/L. min; and GH peak, 34.7 +/- 6.1 microg/L; AUC, 20.25 +/- 3.3 microg/L. min, respectively) and normal subjects (GH peak at 30 minutes, 7.23 +/- 1.35 microg/L; AUC, 4.7 +/- 0.8 microg/L. min; and GH peak at 60 minutes, 41.0 +/- 5.1 microg/L; AUC, 24.3 +/- 1.7 microg/L. min, respectively). SRIH withdrawal resulted in an unequivocal increase in plasma GH concentrations both in CHI patients and in controls, without any significant difference between the 2 groups. A negative correlation was found between the GH response (deltaGH peak) to SRIH withdrawal and CFS (r = -.615, P <.005). In conclusion, our study indicates that patients receiving rehabilitation after leaving the intensive care unit for severe traumatic head injury have no significant changes of GH secretion with normal central regulation of the GH-IGF-1 axis.
