BACKGROUND The diagnosis of Alzheimer's disease (AD) during life remains difficult and a definite diagnosis of AD relies on histopathological confirmation at post-mortem or by cerebral biopsy. It is well known that levels of tau proteins are consistently and significantly increased in the cerebrospinal fluid (CSF) of Alzheimer's patients versus levels in(More)
UNLABELLED The aim of the present study was to search for differences between subtypes of major depression with the use of single photon emission tomography. MATERIALS AND METHODS Fifty (50) patients aged 21-60 years suffering from Major Depression according to DSM-IV took part in the study. The SCAN v 2.0 was used to assist clinical diagnosis. The(More)
Somatostatin is a neuropeptide that confers a wide range of pharmacological properties. Indium-111-tagged pentetreotide ((111)In-P) is a radiolabeled analogue of somatostatin indicated for the in vivo scintigraphic localization of neuroendocrine tumors (NET). In cases of NET of the gastro-intestinal tract we describe the sensitivity compared to conventional(More)
Acute pyelonephritis (APN) is one of the most significant bacterial infections in infancy and early childhood, and can lead to permanent kidney damage and chronic renal failure. To evaluate interleukin-6 (IL-6) and interleukin-8 (IL-8) levels in the urine of children with renal scarring (RS), searching for clinical information about the immuno-inflammatory(More)
OBJECTIVES The differential diagnosis between essential tremor (ET) and Parkinson's disease (PD) may be, in some cases, very difficult on clinical grounds alone. In addition, it is accepted that a small percentage of ET patients presenting symptoms and signs of possible PD may progress finally to a typical pattern of parkinsonism. Ioflupane,(More)
Autosomal dominant familial Parkinson's disease (PD) due to the alpha-synuclein (G209A) mutation shares similar clinical characteristics with sporadic PD. Pathological studies however indicate more widespread neuronal degeneration in the familial form. We performed (123)I-FP-CIT SPET (DaTSCAN) study in nine patients with familial PD carrying the(More)
BACKGROUND Long acting somatostatin analogues combined with platinum analogues have demonstrated an antiproliferative effect on growth of human SCLC xenographs. METHOD 130 previously untreated SCLC patients--54 with limited disease (LD) and positive somatostatin receptors were included in the study. All patients performed 111In-Octreotide scanning before(More)
PURPOSE OF THE STUDY Assess the N30 component of median nerve somatosensory evoked potentials (SEPs) in patients with Parkinson's disease (PD) and correlate its parameters with the severity of the disease, general cognitive ability and regional cerebral blood flow (rCBF). PATIENTS AND METHODS Twenty-three non-demented, non-depressed PD patients (at stage(More)
The aim of the present study was to evaluate the use of the radiopharmaceutical 123I-ioflupane in the diagnosis and differential diagnosis of Parkinsonism (P) and essential tremor (ET). Forty-three consecutive patients, aged 35-72 years, presenting symptoms and signs compatible with P, plus 11 normal volunteers, aged 40-60 years, were enrolled for the(More)
In this article the role of molecular imaging with SPECT and PET in patients with movement disorders is reviewed. It is mentioned that SPECT and PET imaging with cocaine analogues ((123)I-beta-CIT,(123)I-FP-CIT, (18)F-DOPA), radioligands labeling the presynaptic dopamine transporters, is of value for the differentiation of patients with PD or Parkinson-plus(More)
