[Predictive value of the study of cerebro-spinal fluid in neurological diseases. Discriminant analysis of 733 cases].

INTRODUCTION: The study of cerebrospinal fluid (CSF) gives very valuable data for the diagnosis of certain neurological disorders. Objective. To discover the discriminative value of different tests and their usefulness in the study of neurological disorders. MATERIAL AND METHODS: Discriminative multivariate analysis was used for the group of parameters obtained from study of CSF and serum in a sample of 733 patients. BO was included, CSF cytobiochemical data and five of the equations used for calculation of the synthesis of intrathecal IgG. RESULTS: The best discriminative function was expressed as the intrathecal IgG with normal BHE. The formula of Tourtellotte was noteworthy for overestimation of the synthesis of intrathecal IgG when the albumin index indicated BHE rupture. Prospective reclassification of the 733 cases showed that these tests are well worthwhile to rule out immunologically mediated disorders (93% of the cases were correctly reclassified); they suggest the diagnosis in multiple sclerosis (66% correctly reclassified) and give very poor reliability when trying to distinguish between inflammatory infectious processes. CONCLUSIONS: In spite of their undoubted use in supporting the clinical diagnosis, the tests used for study of the synthesis of IgG, even complemented by cytobiochemical examination of the CSF, are not in themselves sufficient for use as a discriminative test in the differential diagnosis of neurological processes.

[Hereditary angioneuritoc edema with exclusive abdominal manifestation. Report of a case].

A new case of C1 inhibitor deficiency is described, pointing out the relationship between laboratory and radiological findings (increase haemoglobin and hematocrit index, and BUN) and presence of free intraperitoneal fluid (ultrasonography and radiology). In patients with this rate condition undergoing laparotomy because acute appendicitis or other surgical condition suspected, the evidence of massive intraperitoneal effusion should indicate the possibility of C1 inhibitor deficiency.

Usefulness of carcinoembryonic antigen determination in bronchoalveolar lavage fluid. A comparative study among patients with peripheral lung cancer, pneumonia, and healthy individuals.

We compared carcinoembryonic antigen (CEA) levels in bronchoalveolar lavage (BAL) fluid and serum of patients with lung cancer, pneumonia, and healthy individuals to determine the usefulness of CEA in diagnosing lung cancer not visible endoscopically. Cancer patients had CEA lavage fluid levels (4,650 +/- 1,565 ng/mg of albumin) significantly higher than pneumonia patients (755 +/- 346 ng/mg) or healthy individuals, smokers (252 +/- 48 ng/ml), and non-smokers (175 +/- 6 ng/mg). In serum, CEA assay cannot discern between cancer (35 +/- 13 ng/ml) and pneumonia (4.6 +/- 1.4 ng/ml) (p = 0.06). Using 1,000 ng/mg of albumin as the cutting point in BAL fluid, sensitivity and specificity were 77 percent and 94 percent, respectively. In serum, 5 ng/ml provided a sensitivity of 55 percent and specificity of 91 percent. Positive and negative predictive values were 77 percent and 94 percent in BAL, respectively, and 62 percent and 89 percent in serum, respectively. Using a combination of serum and BAL fluid CEA levels, the sensitivity and specificity were 88 percent and positive and negative predictive values were 66 percent and 96 percent, respectively. When used in combination with serum levels of CEA or transbronchial biopsy, the diagnostic yield increased up to 88 percent. Thus, although CEA determination in BAL fluid improves diagnostic yield, it should not be used as the only diagnostic procedure.

Changes in total serum IgE concentrations after splenectomy.

In addition to allergic diseases, there are other disorders that can be accompanied by increased levels of total serum IgE. It has been demonstrated that splenectomy can alter the serum concentrations of other immunoglobulins. The aim of this study was to examine the concentrations of total IgE in the serum of patients splenectomized as a result of abdominal trauma but with no associated disease. Our results show that the average concentrations in the serum of patients were significantly higher that in the control group. Furthermore, in a large number of patients, the concentrations were above the normal limit set for the nonatopic Spanish population. These results suggest that splenectomy can alter the regulation of IgE concentrations. Since total IgE is usually determined for diagnostic purposes, it is useful to be aware of this anomaly when dealing with splenectomized patients in order to interpret correctly the laboratory analyses.
