[Meta-analysis of the diagnostic performance of 18F-FDG PET in renal cell carcinoma].

Aim: Renal cell carcinoma is the most frequent solid kidney tumor. At present, PET is not the imaging test of choice, the helical CT being the best method to assess these patients. The aim of the study was to perform a meta-analysis of the literature to evaluate the performance and accuracy of 18F-FDG PET in the detection of primary disease, recurrence and metastasis of renal cell carcinoma.

Diagnosis of orthopedic infection in clinical practice using Tc-99m sulesomab (antigranulocyte monoclonal antibody fragment Fab'2).

Objective: The aim of the study was to analyze the use of Tc-99m-labeled antigranulocyte monoclonal antibody fragment Fab'2 (SMab, Leukoscan) in the diagnosis of acute osteomyelitis and articular prosthesis infection. One hundred seventeen patients (118 studies) have been included, 92 women and 25 men. Thirty-seven had a suspicion of osteomyelitis and 81 with suspicion of infection of a hip (35 patients) or a knee (45 patients) prosthesis.

Cerebral hypoperfusion detected by SPECT in patients with systemic lupus erythematosus is related to clinical activity and cumulative tissue damage.

Cerebral single-photon emission computed tomography (SPECT) is a sensitive technique for the detection of central nervous system (CNS) involvement in systemic lupus erythematosus (SLE). The objective was to determine whether a relationship exists between cerebral hypoperfusion as detected by cerebral SPECT, cumulative tissue damage and the clinical activity of SLE. Cerebral technetium-99m-L,L-ethyl cysteinate dimer (99mTc-ECD) SPECT was performed in two groups of patients: 10 women with SLE (Group A) who had no previous history of major neuropsychiatric (NPS) manifestations and no minor NPS symptoms in the last six months, and 57 unselected women with SLE (Group B).

The dexamethasone suppression test in delusional depression. Further findings.

The results of the overnight 1 mg dexamethasone suppression test (DST) administered to 26 unipolar delusional depressed patients and 47 unipolar non-delusional depressed controls are reported. There were no significant differences between the rates of abnormal responses in the two groups. However, there was a higher percentage of normal responses in the delusional depressive sample with mood incongruency.

Dexamethasone suppression test and familial subtypes of unipolar depression.

We have studied the suppression of plasma cortisol after dexamethasone (1 mg) and the peak post-dexamethasone cortisol values in 84 hospitalized patients with a diagnosis of primary unipolar depression. The non-suppressor responses in the three familial subgroups (Winokur) were: 11/22 in familial pure depressive disorder (FPDD), 21/49 in sporadic depressive disease (SDD) and 1/13 in depression spectrum disease (DSD) (FPDD vs. SDD, p less than 0.

Prolactin secretion response to TRH stimulation in acute and chronic schizophrenic patients under neuroleptic treatment.

Prolactin (PRL) serum levels in a group of patients with acute schizophrenia (AS) and in a group of patients with chronic schizophrenia (CS) have been investigated in order to differentiate the dopaminergic sensitivity in response to chlorpromazine (CPZ) treatment. AS patients show both a greater dopaminergic sensitivity to CPZ and a stronger response in PRL secretion to TRH stimulation after a 14-day CPZ treatment.
