The study is based on 371 cerebrospinal fluid (CSF) samples and 324 serum samples from 40 patients with neurocysticercosis (NC) submitted to treatment with praziquantel. The aim of the study is a critical evaluation on humoral immunity in CSF NC syndrome. The analysis of NC patients at diagnosis and in the follow-up period was performed considering three connected criteria: the clinical one, the CSF examination and the computed tomography. For the study of CSF and serum samples a systematization of collection was scheduled in relation to: diagnosis; period of treatment; follow-up. A total of 13 samples for each case for a follow-up period of two years was scheduled. For the study of humoral immunity a semiquantitative methodology was employed to verify the intra blood-brain barrier (BBB) gamma globulins synthesis. It was based upon electrophoretic profile data on CSF and serum proteins, and relations and indexes. Normal values were previously characterized in a normal control group. This group was formed by 50 patients with chronic headache who presented normal neurological examination, as well as, CSF-examination and serum proteinogram under the safety limits of normality. To verify intra BBB gamma globulins synthesis it was considered the gamma globulin content of the CSF and serum, the gamma globulins/prealbumin + albumin relationship, the Link and Tibbling index, the intra BBB gamma globulins synthesis of Tourtellotte and col., and the appearance of oligoclonal bands in the CSF. Confirmation of the disease was performed by immunological reactions for cysticercosis: complement fixation test in CSF and serum; immunofluorescent test and enzyme-linked immunosorbent assay (ELISA) in CSF. Interference factors in the CSF NC syndrome were analysed at first such as those related to: clinical aspects, time of disease, previous dependence on corticotherapy, ventricular derivation shunts, tomographic findings. It was shown that all of them produce several degrees of interference in the intensity of the CSF NC syndrome. Data on intra BBB gamma globulins synthesis were verified in 37 patients (92.5%). It occurred in a persistent pattern in 18 cases (45%) during all the study phases, and not showed changes that might be related to treatment. On the other hand, it was shown that analysis of the results must always be performed case by case due to large dispersion of events observed and the differences of behavior of data related to humoral immunity, when critically analysed during diagnosis, treatment period and in the follow-up.(ABSTRACT TRUNCATED AT 400 WORDS)

Cerebrospinal fluid IGG and the relations with total protein, and with prealbumin + albumin and the IGG index were studied in 160 patients with various neurological disorders. These patients were distributed in 8 groups according to diagnosis as follows: inflammatory (21 cases); demyelinating (31 cases); degenerative (10 cases); cerebrovascular (19 cases); tumoral (3 cases); convulsive (20 cases); headache (11 cases); other neurological disorders (45 cases). According to the results (table 1) the best applicability of IGG study is the group of chronic inflammatory diseases (neurosyphilis and neurocysticercosis) and the demyelinating disorders (multiple sclerosis). Emphasis is given to the possibility of the occurrence of local synthesis of IGG in the central nervous system in these 2 groups.

Frequently fluid may be aspirated from epidural catheters during epidural anesthesia/analgesia. This fluid may be either cerebrospinal fluid or local anesthetic. Several methods for differentiation of the two fluids have been recommended. In this study, the reliability of the "glucose test" was analyzed. Epidural catheters were inserted into 43 healthy, nondiabetic parturients and then gently aspirated. Aspirate was tested for glucose using glucose oxidase paper. Positive aspirates were assessed for the presence of prealbumin, which is a protein marker for cerebrospinal fluid. Of the patients undergoing cesarean section, 17 of 27 patients yielded a glucose-positive aspirate, and of the patients undergoing labor analgesia, 6 of 16 patients were found to be positive for glucose. None of these patients developed total spinal anesthesia or postdural puncture headache. Visually, none of the aspirates were significantly blood-tinged, blood being a possible source of glucose. When the glucose-positive aspirates were subjected to immunoelectrophoresis, 6 of 7 aspirates revealed a prealbumin band. In conclusion, the glucose test for cerebrospinal fluid may be misleading. The source of this glucose may be normal cerebrospinal fluid drainage into the epidural space.

We present here an unusual case of papillary neuroepithelial tumor of the pineal region. The patient was a 29-year-old female who presented with headaches. A computed tomography scan revealed a tumorous lesion at the pineal region and hydrocephalus. The resected tumor was composed of columnar and cuboidal cells showing characteristics of papillary growth. The tumor cells exhibited diffuse and intense immunoreactivity to cytokeratins and neural cell adhesion molecule. The tumor expressed abundant levels of transthyretin (prealbumin) and appeared ependymal in nature, with numerous microlumens delineated by punctate and ring-like patterns in epithelial membrane antigen staining. Reactivity to synaptophysin and glial fibrillary acidic protein was observed only in the infiltrated non-neoplastic pineal parenchyma. These histological characteristics matched the description of the recently reported papillary tumor of the pineal region thought to originate from the specialized ependyma of the subcommissural organ (SCO). Transthyretin expression of the present case further supports the likelihood of SCO origin, as transthyretin is one of the proteins presumed to be secreted by human SCO.

Beraprost sodium, an orally active prostaglandin I2 analog with vasodilatory, cytoprotective, antiplatelet, antithrombotic, and anti-inflammatory effects, 120 microg daily for 8 weeks, decreased plasma D-dimer, a marker of intravascular coagulation, and von Willebrand factor, a marker for endothelial injury, in 100 chronic peritoneal dialysis patients. Total cholesterol, triglycerides, high-density lipoprotein, apolipoprotein A1, apolipoprotein B, albumin, prealbumin, fibrinogen, troponin-T, and high-sensitivity C-reactive protein levels were not changed. Three patients complained of headache and 1 patient experienced facial flushing; however, no serious adverse effects were observed. These results suggest that beraprost sodium is effective in partially reversing the thrombogenic coagulation profile and endothelial injury in chronic peritoneal dialysis patients.
