Abstract
BACKGROUND In the nineties, there has been evidence that motor evoked potential (MEP) studies might improve the diagnosis of psychogenic paralysis. OBJECTIVE To review a series of patients (1986-1999) who finally had a diagnosis of psychogenic paralysis at our Institutions. To detect if, over that period, the time taken to make the diagnosis had changed, and, if so, this had any relationship to the diagnostic tests used or to other variables. METHODS We selected a patient sample (n=21) seen by the same team of neurologists, whose diagnostic criteria were homogeneously based on the DSM IV, and who were studied with MEPs. We analysed their clinical features, the type and timing of the investigations done, and the time taken to make the diagnosis. These variables acted as the dependent factors in a Multivariate Analysis of Variance (MANOVA) model, in which the year of observation was the fixed factor. RESULTS The diagnosis was 50% earlier in the period 1993 to 1999 (10 patients) than in the period 1986-1992 (11 patients) (F = 28.3, p < 0.0001). The only associated change was an earlier MEP study (F=18.4, p < 0.0001), which invariably showed normal findings. CONCLUSION MEP studies contributed to speed up the diagnosis of psychogenic paralysis. Possibly, normal MEPs rendered the neurologist confident about the physiological integrity of motor fibers in the corticospinal tract, anterior roots and plexuses. Such integrity, if nerve trunks and muscles are intact, and in the appropriate diagnostic context, implies a psychogenic cause for paralysis.

Abstract
The recognition of a pathogen or a vaccine antigen formulation by cells in the innate immune system leads to production of proinflammatory cytokines, which will determine the ensuing acquired immune response quantitatively and qualitatively. Tumour necrosis factor (TNF)-alpha, interleukin (IL)-1 and IL-6 are the first set of cytokines produced upon such an encounter, which have roles both in protective immunity and immunopathogenesis evident with respiratory syncytial virus (RSV). RSV antigens in different physical adjuvant-vaccine formulations were analysed for their capacity to provoke cultured murine peritoneal cells to produce these three proinflammatory cytokines. RSV immunostimulating complex (ISCOM), i.e. both antigen and adjuvant are incorporated in the same particle, induced high levels of IL-1alpha being of the same magnitude or higher than those of live RSV and lipopolysaccharide (LPS). Live virus and LPS induced higher levels of IL-6 and TNF-alpha than ISCOM and so did non-adjuvanted UV-inactivated RSV but only at high doses. ISCOM-Matrix, i.e. ISCOM without antigens, admixed as a separate entity to inactivated RSV, downregulated or blocked the cytokine response to the inactivated RSV in contrast to ISCOM. Kinetic studies showed that ISCOM induced cytokine production first detected at hours 1, 2, 4 for TNF-alpha, IL-6 and IL-1alpha respectively, which was earlier than for the other antigen formulations containing corresponding doses of antigen and/or Quillaja adjuvant. Peak values for production of TNF-alpha and IL-6 were at 8 h and for IL-1alpha at 72 h following stimulation with ISCOM. The delayed appearance of IL-1alpha may reflect the cell-bound nature of this cytokine.

Abstract
PURPOSE Description of the involvement of the transcription factor NF-kB in inflammatory, autoimmune and neoplastic processes. Clinical implications from basic research. DESIGN Review of the most significant data reported in the literature and personal publications. RESULTS NF-kB is an ubiquitous transcription factor member of the proto-oncogene family rel. NF-kB regulates the expression of several genes involved in inflammatory and immune responses. The classical activated form of NF-kB consists of the p50/p65 heterodimer, different dimers may be formed with members of rel, AP1, steroid hormones receptors family. Many studies suggest that NF-kB should be considered as an important mechanisms of inflammatory processes and autoimmune diseases. Many important anti-inflammatory drugs and immunosuppressants inhibit NF-kB. Several observations have suggested a role of the inappropriate activation of NF-kB in cell proliferation, transformation, and tumor development, mainly lymphomas. Conversely, it has been proposed that the activation of NF-kB in immune cells may contribute to anti-tumor immunity. CONCLUSIONS NF-kB is an optimal target of anti-inflammatory and immunosuppresant therapies. Molecular studies on NF-kB are very important to understand the pathogenesis of inflammatory, autoimmune and neoplastic diseases, and to identify new drugs that inhibit NF-kB activation.

Abstract
In order to investigate phamacotherapeutic responsiveness of major depression and other behavioural disturbances associated with traumatic brain injury (TBI), 20 post-TBI patients were diagnosed as being depressed by two independent neuropsychiatrist observers, out of 37 consecutive TBI subjects sent to psychiatric counselling for poor compliance during rehabilitation programmes or psychiatric/behavioural disturbances after return to society. They were subsequently divided into two subgroups, depending on time elapsed from trauma (A: within 6 months; B: at 24-36 months post-trauma) and were enrolled in an open informed pharmachological study. Rating at baseline included Glasgow Coma Score on hospital admission, length of coma, length of hospitalization, Functional Independence Measure (FIM), Brief Psychiatric Rating Scale (BPRS) and Clinical Global Impression scale (CGI). BPRS and CGI were repeated after 12 weeks of oral administration of citalopram (20 mg a day) and carbamazepine (600 mg a day). At baseline, psychiatric symptoms in group B were worse than in group A (particularly somatic overconcern, anxiety, depressed mood, psychomotor slowness, inappropriate and labile affect). At T1, the global (group A and B combined) CGI and BPRS scores showed a statistically significant improvement when compared with T0, even if group B scores remained higher than group A. The results of this study suggest that: (a) citalopram combined with carbamazepine is effective in reducing depression and behavioural disorders following TBI, and (b) these disturbances should be addressed as soon as possible during the acute rehabilitation period.

Abstract
A phase II trial evaluated the effectiveness and toxicity of combination paclitaxel (Taxol), gemcitabine (Gemzar), and trastuzumab (Herceptin) as first-line therapy for patients with newly diagnosed HER2-overexpressing metastatic breast cancer. To date, 27 patients have received paclitaxel at 175 mg/m2 over 3 hours on day 1, plus gemcitabine at 1,200 mg/m2 on days 1 and 8, plus trastuzumab at a 4-mg/kg loading dose on day 1, followed by 2 mg/kg weekly. Treatment cycles were repeated every 21 days. Responding or stable patients who had received six cycles of combination therapy continued single-agent trastuzumab weekly until disease progression. Treatment was generally well tolerated with grade 4 toxicity limited to myelosuppression. In all, 12 patients have achieved a partial remission and 1 patient had progressive disease; 14 patients continue treatment and have not yet been evaluated for response. Combination treatment with paclitaxel, gemcitabine, and trastuzumab is well tolerated and appears to be highly active. Accrual will continue to a total enrollment of 46 patients.

Abstract
BACKGROUND Fas (CD95) triggers programmed cell death and is involved in shutting off the immune response. Inherited deleterious mutations hitting Fas or its signaling pathway cause autoimmune/lymphoproliferative syndrome (ALPS). OBJECTIVE To assess the possibility that decreased Fas function plays a role in development of MS. METHODS The authors evaluated Fas function in long-term T cell lines (21 days of culture) from 32 patients with relapsing-remitting MS (RRMS), 15 with secondary progressive MS (SPMS), and 15 with primary progressive MS (PPMS) by assessing cell survival upon Fas triggering by monoclonal antibodies (Mab). RESULTS Fas-induced cell death was significantly lower in all patient groups than in controls, and lower in SPMS than in RRMS. Moreover, 8/15 patients with PPMS, 10/15 with SPMS, and 8/32 with RRMS were frankly resistant to Fas. Frequency of resistance to Fas-induced cell death was significantly higher in all patient groups than in controls (2/75), and higher in SPMS than in RRMS. The findings that the parents of two Fas-resistant patients were Fas-resistant and that fusion of T cells from two Fas-resistant patients with Fas-sensitive HUT78 cells gave rise to Fas-resistant hybrid lines suggest that Fas-resistance is due to inherited alterations of the Fas signaling pathway, with production of molecules exerting a dominant negative effect on a normal Fas system. CONCLUSIONS Defects of the immune response shutting-off system may be involved in the pathogenesis of MS, particularly in its progressive evolution.

Abstract
The Authors report a case of rupture of the diaphragm in blunt trauma of the abdomen, to examine the more significant features of this condition whose incidence proves to be increasing, after a review of the literature data, parallel to the increase of accidents on the road and at work. They examine the most important pathogenic problems and these related to the mechanism leading to diaphragmatic lesion and they highlight the deeper pathophysiological changes suffered from the patient with such a condition. They draw attention to what they consider to be the most important aspect, and therefore the diagnosis. In fact, in accordance with the various series of cases reported in the literature, it is crucial in the diagnostic problem is when the possible cause of the rupture is suspected and necessary diagnostic cascade (Rx, echotomography, TC) is activated so to highlight the lesion. Therefore a quick diagnostic fitting is necessary for the survival of the acute patient with hernia of the thorax cavity, as well as quick surgical correction of the lesion that, as in the case described, serves to achieve the best possible anatomic-functional results.

Abstract
To evaluate the advantages of thyroidectomy under assisted local anesthesia, 35 cases operated on from January 1998 to February 1999 were reviewed. The patients were studied in ambulatory setting and adequately informed on the program of thyroid operation under local anesthesia. Multinodular goitre was present in all the cases. In 12 cases, it was intrathoracic. The morning of operation, all the patients underwent to pre-operative sedation and, in operative room, to local anesthesia with Mepivacaine 1% and adrenaline 1,200,000 U. The operations were performed with a mean of 30 cc of local anesthetic. During operation, in none case the conversion to general anesthesia was necessary. No mortality and morbility were registered. In the majority of cases, an analgesic was necessary meanly 4 hours after operation. The evening of operation in all the patient oral nutrition was restored. Twenty-nine patients were discharged from the hospital 48 hours after surgery. Eight days after operation, surgical recovery was evident in all the patients reviewed in the out patients setting. The advantages of thyroid surgery under assisted local anesthesia are outlined.

Abstract
PURPOSE To assess whether single-and paired-pulse transcranial magnetic stimulation (TMS) can measure the interictal brain excitability of medicated patients with cryptogenic localization related epilepsy (CLE). Changes in the balance between excitation and inhibition are the core phenomena in focal epileptogenesis. TMS can assess this balance in the primary motor cortex. METHODS We selected 18 patients with CLE and similar clinical features in whom we located the epileptogenic area reliably, with 11 age-and sex-matched healthy controls. For both motor cortices, we determined the threshold to TMS, the duration of the cortical silent period, and the corticocortical inhibition and facilitation curve. RESULTS TMS was safe. The more antiepileptic drugs (AEDs) taken by the patients, the higher their threshold to TMS. The silent period duration failed to show significant changes. On paired TMS, a cluster analysis identified a homogeneous subgroup of patients (n = 7) who showed a significantly defective corticocortical inhibition and excess facilitation. With respect to the epileptogenic area, the phenomenon was bilateral in four of these patients, ipsilateral in two, and contralateral in one. The phenomenon was independent of AEDs and many other clinical variables. However, this patient group had a higher seizure frequency and a higher proportion of electroencephalograms (EEGs) showing interictal generalized epileptic discharges than the rest of the patients. CONCLUSION Paired TMS provided a valuable pathophysiologic insight into the interictal excitatory state of the cortex in CLE. This method can potentially supply useful prognostic clinical information.

Abstract
In the last years the video-assisted thoracic surgery (V.A.T.S.) assumed an important order for the diagnosis and treatment of the pleural disease. In this particular field, the procedure allows obtaining almost the same outcomes of traditional surgery and is very safety. V.A.T.S. reduces hospital time and trauma with a fast return to the working life. The Authors describe their experience and outline the diagnostic and therapeutic indications for the treatment of choice and emergency.

Abstract
Transforming growth factor (TGF)-beta1-decreased major histocompatibility complex (MHC) class I gene expression in thyrocytes is transcriptional; it involves trans factors and cis elements important for hormone- as well as iodide-regulated thyroid growth and function. Thus, in rat FRTL-5 thyrocytes, TGF-beta1 regulates two elements within -203 bp of the transcription start site of the MHC class I 5'-flanking region: Enhancer A, -180 to -170 bp, and a downstream regulatory element (DRE), -127 to -90 bp, that contains a cAMP response element (CRE)-like sequence. TGF-beta1 reduces the interaction of a NF-kappaB p50/fra-2 heterodimer (MOD-1) with Enhancer A while increasing its interaction with a NF-kappaB p50/p65 heterodimer. Both reduced MOD-1 and increased p50/p65 suppresses class I expression. Decreased MOD-1 and increased p50/p65 have been separately associated with the ability of autoregulatory (high) concentrations of iodide to suppress thyrocyte growth and function, as well as MHC class I expression. TGF-beta1 has two effects on the downstream regulatory element (DRE). It increases DRE binding of a ubiquitously expressed Y-box protein, termed TSEP-1 (TSHR suppressor element binding protein-1) in rat thyroid cells; TSEP-1 has been shown separately to be an important suppressor of the TSH receptor (TSHR) in addition to MHC class I and class II expression. It also decreases the binding of a thyroid-specific trans factor, thyroid transcription factor-1 (TTF-1), to the DRE, reflecting the ability of TGF-beta1 to decrease TTF-1 RNA levels. TGF-beta1-decreased TTF-1 expression accounts in part for TGF-beta1-decreased thyroid growth and function, since decreased TTF-1 has been shown to decrease thyroglobulin, thyroperoxidase, sodium iodide symporter, and TSHR gene expression, coincident with decreased MHC class I. Finally, we show that TGF-beta1 increases c-jun RNA levels and induces the formation of new complexes involving c-jun, fra-2, ATF-1, and c-fos, which react with Enhancer A and the DRE. TGF-beta1 effects on c-jun may be a pivotal fulcrum in the hitherto unrecognized coordinate regulation of Enhancer A and the DRE.

Abstract
In this study we examined the effect of the synthetic peptide thymosin-alpha1 (T(alpha)1) on MHC class I expression in FRTL-5 cells. Treatment with T(alpha)1 increased expression of MHC class I surface molecules and mRNA, which reached its peak (153 +/- 8 % of the control value) after 12 h. Chloramphenicol acetyltransferase (CAT) analysis, following transfection with a plasmid containing the regulatory sequence of MHC class I (or its deletion derivatives) with the CAT reporter gene, and electrophoretic mobility shift assay experiments demonstrated that the action of T(alpha)1 was at the transcriptional level, and its mechanism of action is likely due to increased binding between the complex p50/fra-2 and the enhancer A sequence of the 5' flanking region of a swine class I gene (PD1). An increase in the expression of MHC class I surface molecules was also observed by flow cytometry in murine and human tumor cell lines and in primary cultures of human macrophages. This study shows for the first time an effect of Talpha1 on the regulation of gene expression at the molecular level, and may further contribute to explaining the results obtained using Talpha1 in the control of infectious diseases and tumor growth.

Abstract
PURPOSE To assess the clinical impact of monitoring serum concentrations of antiepileptic drugs (AEDs) in patients with newly diagnosed epilepsy. METHODS One-hundred eighty patients with partial or idiopathic generalized nonabsence epilepsy, aged 6 to 65 years, requiring initiation of treatment with carbamazepine (CBZ), valproate (VPA), phenytoin (PHT), phenobarbital (PB), or primidone (PRM) were randomly allocated to two groups according to an open, prospective parallel-group design. In one group, dosage was adjusted to achieve serum AED concentration within a target range (10-20 microg/ml for PHT, 15-40 microg/ml for PB, 4-11 microg/ml for CBZ, and 40-100 microg/ml for VPA), whereas in the other group, dosage was adjusted on clinical grounds. Patients were followed up for 24 months or until a change in therapeutic strategy was clinically indicated. RESULTS Baseline characteristics did not differ between the two groups. Most patients with partial epilepsy were treated with CBZ, whereas generalized epilepsies were most commonly managed with PB or VPA. PHT was used only in a small minority of patients. A total of 116 patients completed 2-year follow-up, and there were no differences in exit rate from any cause between the monitored group and the control group. The proportion of assessable patients with mean serum drug levels outside the target range (mostly below range) during the first 6 months of the study was 8% in the monitored group compared with 25% in the control group (p < 0.01). There were no significant differences between the monitored group and the control group with respect to patients achieving 12-month remission (60% vs. 61%), patients remaining seizure free since initiation of treatment (38% vs. 41%), and time to first seizure or 12-month remission. Frequency of adverse effects was almost identical in the two groups. CONCLUSIONS Only a small minority of patients were treated with PHT, the drug for which serum concentration measurements are most likely to be useful. With the AEDs most commonly used in this study, early implementation of serum AED level monitoring did not improve overall therapeutic outcome. and the majority of patients could be satisfactorily treated by adjusting dose on clinical grounds. Monitoring the serum levels of these drugs in selected patients and in special situations is likely to be more rewarding than routine measurements in a large clinic population.

Abstract
This review considers the relevance of pharmacokinetic interactions between antiepileptic drugs (AEDs) and psychoactive drugs in the treatment of mood disorders in patients with epilepsy. The determination of plasma levels of some of these drugs (mainly the AEDs) has enabled clinicians to evaluate the kinetic modifications during the course of such combined therapies and to adjusting the dosages in cases of subtherapeutic or toxic levels. In general, phenobarbital, phenytoin, and carbamazepine stimulate the catabolic degradation of tricyclic antidepressants (TCAs), and TCAs have an inhibitory effect on the elimination of AEDs. The newer antidepressants that selectively inhibit the reuptake of serotonin (SSRIs), although in different fashions for the different substances (fluoxetine, fluvoxamine, paroxetine) may cause an increase of plasma AED levels through inhibition of the isoenzyme P450 2D6. Similarly, antipsychotics (APs) are more rapidly metabolized when AEDs are co-administered, whereas AED metabolism is scarcely influenced by AP. Finally, plasma levels of tranquilizers are lowered by AED co-therapy. As the concomitant administration of AED and psychoactive drugs becomes increasingly used for treatment of mood disorders in patients with or without epilepsy, therapeutic drug monitoring may be useful in designing correct and rational therapy.

Abstract
PURPOSE To compare vinblastine versus the combination of vinblastine plus estramustine as treatment for patients with hormone-refractory prostate cancer (HRPC). PATIENTS AND METHODS A total of 201 patients with metastatic prostate cancer, progressive after hormonal therapy and antiandrogen withdrawal (if prior antiandrogen treatment), were randomized to receive vinblastine (V) 4 mg/m(2) by intravenous bolus weekly for 6 weeks followed by 2 weeks off, either alone or together with estramustine phosphate (EM-V) 600 mg/m(2) PO days 1 through 42, repeated every 8 weeks. Of 193 eligible patients, 98 received V, and 95 received EM-V. RESULTS Overall survival trended in favor of EM-V but was not significantly different as determined by Kaplan-Meier analysis (P =.08). Median survival was 11.9 months for EM-V and 9.2 months for V. EM-V was superior to V for secondary end points of time to progression (P <. 001, stratified log rank test; median 3.7 v 2.2 months, respectively) and for proportion of patients with >/= 50% prostate-specific antigen (PSA) decline sustained for at least 3 monthly measurements (25.2% v 3.2%, respectively; P <.0001). Granulocytopenia was significantly less for EM-V compared with V (grade 2, 3, and 4 = 7%, 7%, and 1% v 27%, 18% and 9%, respectively; P <.0001); however, grade 2 or worse nausea (26% v 7%, respectively; P =.0002) and extremity edema (22% v 8%, respectively; P =.005) were more frequent for EM-V. CONCLUSION Although overall survival was not significantly greater for the combination, EM-V was superior to V for time to progression and PSA improvement. These results encourage further study of estramustine-based antimicrotubule drug combinations in HRPC.

Abstract
PURPOSE To evaluate the efficacy and toxicity of combination and sequential dose-dense chemotherapy with doxorubicin and docetaxel (Taxotere; Rhône-Poulenc Rorer, Collegeville, PA) as primary chemotherapy of breast cancer. PATIENTS AND METHODS Patients with newly diagnosed stage II or noninflammatory stage III breast cancer were randomly assigned to receive the same total doses of doxorubicin and docetaxel over a 12-week period before definitive surgery. Patients in arm A received sequential therapy with doxorubicin 75 mg/m(2) every 2 weeks for three cycles followed by docetaxel 100 mg/m(2) every 2 weeks for three cycles. Patients in arm B received combination therapy with doxorubicin 56 mg/m(2) plus docetaxel 75 mg/m(2) every 3 weeks for four cycles. Granulocyte colony-stimulating factor was administered on days 2 to 12 of each cycle in both groups. RESULTS Forty patients were entered onto the trial. Pretreatment tumor size averaged 5.7 cm with clinically positive axillary lymph nodes in 23 patients (57%). As expected, myelosuppression was severe in both groups; however, >/= 80% of planned dose-intensity was delivered. Hand-foot syndrome was more common after sequential therapy. Clinical responses were similar in both groups, with an overall response rate of 87%, including 20% clinical complete remissions. Pathologic complete remission or residual in situ disease only was confirmed in five patients (12.8%). Patients who received sequential therapy had fewer positive lymph nodes (mean, 2.17 v 4.81; P <.037) at definitive surgery. CONCLUSION Primary chemotherapy with doxorubicin and docetaxel is well tolerated and highly active. A sequential treatment schedule increases toxicity but may result in more substantial lymph node clearance than combination therapy.

Abstract
The recent cloning of human TSH-beta gene has allowed the production of recombinant human TSH (rhTSH) by recombinant DNA technology in mammalian cells (Chinese hamster ovary cells). Studies aimed at biochemical and biological characterization have shown that rhTSH, unlike pituitary TSH, is highly sialylated and is biological active in stimulating c-AMP accumulation in FRTL-5 cells. Phase I/II and phase III clinical studies have been performed to evaluate the safety and efficacy of rhTSH in stimulating radioactive iodine uptake in patients after total thyroidectomy for differentiated thyroid cancer. In these patients therapy with thyroid hormones is performed to replace hormone production and to suppress TSH-stimulated tumor growth. To detect residual or recurrent cancer, the therapy has to be withdrawn in order to obtain rise in endogenous TSH to perform a total body scan. rhTSH, as a source of exogenous human TSH, has been shown as an additional diagnostic tool in the follow-up of patients with thyroid cancer. Used in patients maintained on thyroid hormone suppressive therapy, rhTSH enhances the sensitivity of serum Tg testing. Although the sensitivity of scans obtained after rhTSH administration is slightly lower than that after thyroid hormone withdrawal, the use of rhTSH avoids the clinical signs and symptom of hypothyroidism and can be used in selected patients.

Abstract
In subjects affected by trisomy 21 (Down syndrome), hypothyroidism is the most common endocrinological deficit. Plasma zinc levels, which are commonly detected below the normal range in Down patients, are related to some endocrinological and immunological functions; in fact, zinc deficiency has been shown to impair immune response and growth rate. Aims of this study were to evaluate (1) the role of zinc deficiency in subclinical hypothyroidism and (2) thyroid function changes in Down children cyclically supplemented with zinc sulfate. Inverse correlations have been observed between age and triiodotironine (T3) and between zinc and thyroid-stimulating hormone (TSH); higher TSH levels have been found in hypozincemic patients at the beginning of the study. After 6 mo of supplementation, an improvement of thyroid function (TSH levels: 3.96 +/- 1.84 vs 2.64 +/- 1.33 mUI/mL basally and after 6 mo, respectively) was observed in hypozincemic patients. In the second cycle of supplementation, a similar trend of TSH was observed. At the end of the study, TSH significantly decreased in treated hypozincemic subjects (4.48 +/- 1.93 vs 2.96 +/- 1.20 mUI/mL) and it was no longer different in comparison to normozincemic patients. We suggest zinc supplementation to the diet in hypozincemic Down children as a simple and useful therapeutic tool.

Abstract
This phase II trial investigated the activity and toxicity of CODE (cisplatin, vincristine, doxorubicin, etoposide) chemotherapy with the addition of granulocyte colony-stimulating factor (G-CSF) in patients who had chemotherapy-naive, advanced, or metastatic non-small-cell lung cancer. Treatment consisted of cisplatin, 25 mg/m2, administered weeks 1 through 9; vincristine, 1 mg/m2, weeks 1, 2, 4, 6, and 8; doxorubicin, 40 mg/m2, weeks 1, 3, 5, 7, and 9; and etoposide, 80 mg/m2 intravenously day 1 and 160 mg/m2 orally, days 2 and 3 on weeks 1, 3, 5, 7, and 9. Granulocyte colony-stimulating factor, 5 microg/kg, was administered subcutaneously on all days that patients were not receiving chemotherapy. From April 1992 through April 1993, 42 patients were entered on study. The principal toxicities were hematologic. Grade 3-4 anemia was seen in 21 patients. Grade 3-4 thrombocytopenia was seen in 9 patients. Grade 3-4 neutropenia occurred in 29 patients. Eight patients experienced a neutropenic febrile episode requiring antibiotics. Nonhematologic toxicities included weight loss and fatigue. Responses were seen in 10 of 42 patients, for an overall response rate of 24% (95% confidence interval, 12%-39%) and a median survival of 7.1 months. The CODE chemotherapy regimen has activity similar to other previously described cisplatin-based regimens, with a significant amount of both hematologic and nonhematologic toxicity. Its continued use in patients who have previously untreated non-small-cell lung cancer cannot be recommended, based on the results of this study.

Abstract
The purpose of this study was to compare the objective response rate, duration of remission, and survival of 5-fluorouracil (5-FU) versus those of 5-FU plus levamisole in metastatic colorectal cancer using the same dose and schedule of these agents as in the North Central Cancer Treatment Group and intergroup studies of adjuvant therapy. Patients with no prior history of chemotherapy for metastatic disease were entered on this Hoosier Oncology Group randomized Phase III trial. Patients were stratified by Karnofsky performance status and presence or absence of liver metastases. They were randomized to receive 450 mg/m2 5-FU i.v. for 5 days followed by 15 mg/kg i.v. weekly (arm 1) or the same dose of 5-FU plus levamisole 50 mg p.o. every 8 h for 3 days every 2 weeks (arm 2). The duration of treatment for both arms was 26 weeks. From April 1990 to March 1995, 199 patients were entered. One hundred eighty-two patients, 91 in each arm, were fully evaluable. The response rates were 12% on arm 1 and 13% on arm 2. The median duration of response was 18 weeks on both arms. The median survival was 48 weeks on arm 1 and 41 weeks on arm 2 (P = 0.20). This study failed to show any improvement in survival, response, or duration of remission with the addition of levamisole to 5-FU in the treatment of metastatic colorectal cancer.

Abstract
The Hoosier Oncology Group conducted a trial evaluating ifosfamide in patients who had recurrent or metastatic squamous cell carcinoma of the head and neck. Patients must have received no prior chemotherapy for metastatic disease. If prior adjuvant chemotherapy was given, the last cycle must have been at least six months from time of recurrence. All patients were required to have a Karnofsky performance status of > or = 50. Twenty-four patients received treatment consisting of ifosfamide, 1.5 g/m2/day for 5 days, with cycles repeated every 3 weeks. Mesna, 300 mg/m2, was administered intravenously 15 minutes before ifosfamide and 4 and 8 hours after ifosfamide on days 1 through 5. Toxicity was predominantly hematologic, with grade 3--4 neutropenia seen in 13 patients resulting in 4 episodes of neutropenic fever. One partial response was seen in 23 evaluable patients for an overall response rate of 4.3% (95% confidence interval, 0, 12.7%). In conclusion, ifosfamide would appear to have limited single-agent activity in squamous cell carcinoma of the head and neck.

Abstract
Of 14 patients with a history of partial epilepsy who received vigabatrin 2 g daily for 6 months, eight were newly diagnosed and received vigabatrin as monotherapy, while the remaining six received vigabatrin in addition to pre-existing treatment with phenobarbitone. Neurophysiological and neuropsychological evaluations, done before and after the therapeutic period, included the Luria-Nebraska neuropsychological battery (LNNB), electroencephalograms (EEGs) and evoked potentials. The results for each item of the test battery at baseline were compared with those after 6 months' treatment. There were no statistically significant differences on the functional scales of the LNNB, the EEG or the evoked potentials. There was a significant improvement (P = 0.01) in the LNNB topographic scales for the right frontal lobe and the motor-sensory area following treatment. These results indicate that vigabatrin has no detrimental effects on cognitive function and may improve function.

Abstract
It has been shown recently that Selenium (Se), an essential trace element for humans, is involved in the regulation of thyroid function, since the enzyme that catalyzes the liver conversion of the thyroid hormone T4 to the more active form T3 is a selenoenzyme. In chronic uremic patients, low blood Se levels as well as thyroid function abnormalities are often found. The present study was carried out to verify whether any correlation exists between Se levels and thyroid function, and to evaluate possible changes in hormonal pattern during Se supplementation in 10 chronic uremic patients on hemodialysis (HD) treatment. Se was supplemented orally as sodium selenite over six consecutive months. Basic plasma Se levels were significantly lower in patients than in normal controls. Right from the start of Se supplementation, plasma Se concentration promptly normalized and leveled off in the normal range throughout the study. Significant increase of FT3 and reduction of TSH levels were detected during Se supplementation. In Se-supplemented patients, a significant direct correlation was also found between reverse T3 (rT3) and TSH, and a significant inverse correlation was found between Se and TSH. Our results suggest that Se deficiency in chronic uremic patients represents a factor influencing the thyroid function and that the Se status should be determined in the evaluation of thyroid metabolism in these patients.

Abstract
OBJECTIVE To compare the hospital course and clinical outcome of preterm infants with respiratory distress syndrome treated with surfactant and managed with high-frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CV) as their primary mode of ventilator support. DESIGN A prospective randomized clinical trial. SETTING Three community-based level III neonatal intensive care units. SUBJECTS A total of 125 neonates who were 35 weeks or less estimated gestation requiring intubation and assisted ventilation for respiratory distress syndrome with arterial to alveolar oxygen ratio less than .50. INTERVENTIONS Patients were randomized to continue CV (61 patients) or be changed to HFOV (64 patients) after exogenous surfactant administration (100 mg/kg). HFOV was used in a strategy to promote lung recruitment and maintain lung volume. Protocol respiratory care guidelines were followed; otherwise routine care was provided by each neonatal intensive care unit. MEASUREMENTS AND MAIN RESULTS No differences were noted in demographic features between the two study groups. The study population birth weight was 1.51 +/- .47 kg (mean +/- SD), gestational age was 30.9 +/- 2.5 weeks, and study entry age was 2 to 3 hours. Patients randomized to HFOV demonstrated the following significant findings compared with CV-treated patients: vasopressor support was less intensive; surfactant redosing was not as frequent; oxygenation improved more rapidly and remained higher during the first 7 days; fewer infants required prolonged supplemental oxygen or ventilator support; treatment failure was reduced; more patients survived without chronic lung disease at 30 days; need for continuous supplemental oxygen at discharge was less; frequency of necrotizing enterocolitis illness was lower; there were fewer abnormal hearing tests; and hospital costs were decreased. No differences were seen between the two study groups in the frequency or severity of patent ductus arteriosus, air leak, retinopathy of prematurity, or intraventricular hemorrhage. Length of hospital stay and survival to discharge were similar for HFOV- and CV-treated infants. CONCLUSIONS When used early with a lung recruitment strategy, HFOV after surfactant replacement resulted in clinical outcomes consistent with a reduction in both acute and chronic lung injury. Benefit was evident for preterm infants both less than or equal to 1 kg and more than 1 kg. In addition, early HFOV treatment may have had a more global effect on patient health throughout the hospitalization, resulting in reduced morbidity and decreased health care cost.

Abstract
Studies were reviewed in which patients who received vigabatrin underwent cognitive testing. The overall results were categorized into five areas of cognitive function: reception, attention, intellectual function, memory, and psychomotor function. Overall, the studies showed either no detrimental effects or, in some cases, slightly improved function. It is speculated that a relationship exists between GABA and the results of these studies because vigabatrin enhances the GABAergic mechanism in the CNS.

Abstract
We studied one sample of commercial sepiolite and two samples of commercial vermiculite--clay minerals proposed as replacements for asbestos--and tested in vitro their abilities to activate complement, to lyse erythrocytes, and to elicit the production of reactive oxygen species (ROS) with human polymorphonuclear leukocytes (PMN) or bovine alveolar macrophages (AM); their behavior was compared with that of asbestos fibers obtained from the Union International Contra Cancer (UICC) as reference standards, as well as with kaolinite and illite, main members of the clay mineral family. Since in short-term in vitro tests the biological activity of mineral particles seems especially related to the active sites on their surface, we first measured the specific surface area of each mineral. Sepiolite was unreactive in two of the three tests we used (complement activation and ROS production) and able to lyse a minimal percentage of red blood cells. Vermiculite was shown to be incapable of activating complement, to have a moderate hemolytic activity and a high ability to elicite ROS production, although lower than that of chrysotile. Sepiolite, therefore, might be of more interest than vermiculite, given the low level of biological effects detected during the tests used to compare both clay minerals with asbestos fibres. The ROS production does not seem to require phagocytosis. A high ROS production was observed with kaolinite: this result casts doubt on the ability of pathogenic mineral dusts in vitro to induce a greater release of ROS than nonpathogenic mineral dusts.

Abstract
PURPOSE To determine whether the addition of ifosfamide to cisplatin plus etoposide improves the response rate, time to disease progression, or overall survival in previously untreated patients with extensive-stage small-cell carcinoma of the lung (SCLC). PATIENTS AND METHODS Patients with extensive SCLC with a Karnofsky performance score (KPS) > or = 50 and adequate renal function and bone marrow reserve were eligible. Patients with CNS metastases were eligible and received concurrent whole-brain radiotherapy. Patients were randomized to receive cisplatin (20 mg/m2) plus etoposide (100 mg/m2) (VP) both given intravenously (i.v.) on days 1 to 4 or cisplatin (20 mg/m2), ifosfamide (1.2 g/m2), and etoposide (75 mg/m2) (VIP) all given i.v. on days 1 to 4. Cycles were repeated every 3 weeks for four cycles. RESULTS From May 1989 through March 1993, 171 patients were randomized (84 to VP and 87 to VIP). The median follow-up duration is 26 months. All patients were assessable for survival; 163 were fully assessable for response and 162 for toxicity. Myelosuppression was greater with VIP. Objective responses were observed in 55 of 82 (67%) and 59 of 81 (73%) assessable patients treated with VP and VIP, respectively (difference not significant). The difference in the median time to progression was statistically different (P = .039). The median survival times on VP and VIP were 7.3 months and 9.0 months, respectively (P = .045 for survival curves by stratified log-rank test) with 2-year survival rates of 5% versus 13%, respectively. CONCLUSION VIP combination chemotherapy is associated with an improved time to progression and overall survival over VP therapy in patients with extensive SCLC.

Abstract
We have studied a sample of commercial sepiolite and two samples of commercial vermiculite which are advised to replace asbestos, and we have in vitro tested their abilities to activate the complement and to lyse erythrocytes. Their behaviours has been compared with those of asbestos fibres given by Union Internationale Contre le Cancer (UICC) as reference standards. We have first measured the specific surface area and the weight of each mineral. Sepiolite has been inactive in complement activation and little able to lysis red blood cells on the base of surface area; on the base of the weight it has been unreactive in complement activations but very reactive in red blood cells lysis. We believe that in the in vitro assays to evaluate the biological effects of the substitutes of asbestos it is very important to considerate as the weight and as the specific surface are of each clay mineral.

Abstract
We have verified that chemotaxis of isolated human polymorphonuclear leukocytes (PMN) was a target of in vitro toxicant effect of acrylonitrile (ACN). This toxicant induced a significant dose dependent decreasing of chemotaxis with 50% inhibition (IC50) occurring at 15 mM. We assume that PMN from workers exposed to ACN reacts vivo in a similar way to PMN exposed in vitro to ACN. We propose therefore to use chemotaxis assay as a biomarker of early biological effect of ACN in workers, since for their monitoring there are so far only internal dose indicators but no suitable effect indicators.

Abstract
Human polymorphonuclear leukocytes (PMN) were chosen to measure two cellular end points--chemotaxis and respiratory burst--and to verify whether they could function as biomarkers of early effect in detecting occupational exposure to n-hexane of apparently healthy shoe workers, without any electroneuromyographic (ENMG) abnormality. Chemotaxis, but not respiratory burst, was found to be impaired. A negative linear correlation between chemotaxis of PMN of those workers that had been exposed to n-hexane versus 2,5-hexanedione (2,5-HD) urinary concentrations were found. This negative trend is consistent with our previous in vitro experimental findings: it was observed that the progressive addition of 2,5-HD to PMN suspensions inhibited chemotaxis in a dose-dependent mode, while chemiluminescence was not modified. Now we have confirmed in vivo that chemotaxis is more sensitive than the respiratory burst response to 2,5-HD. Such results justify the interest in the behaviour of PMN harvested from workers exposed to n-hexane. Since significant inhibition of chemotactic activity was observed in some workers whose urinary 2,5-HD levels were lower than 5 mg l-1, which is the biological exposure index suggested by ACGIH, this study suggests that PMN chemotaxis may be proposed as a useful biomarker in detecting occupational exposure to low level of n-hexane.

Abstract
Hypersensitivity to latex gloves has often been reported in patients who have undergone surgical treatment. Recent reports suggest that latex antigens can produce cutaneous and respiratory symptoms in workers occupationally exposed to latex. Four such cases of healthcare workers who were sensitized through exposure to latex have been observed. Two of these workers presented dermatitis as well as work-related respiratory symptoms, while the others only showed symptoms suggesting occupational asthma. The subjects were diagnosed as having latex hypersensitivity after skin prick-testing, and the immunoglobulin E serum level against latex gave positive results. In addition, changes in methacholine responsiveness also took place. In one case, an occupational exposure test was carried out which resulted in a 24% drop in the FEV1 value after 25 min of inhalation exposure. At least one year after the diagnosis, two nurses (subjects A and D) who had been removed completely from latex exposure experienced no further latex-induced symptoms. The other workers, who have continued working in the same laboratories using vinyl gloves, now display less severe symptoms but require regular anti-allergy treatment.

Abstract
Twenty-two plasma amino acids were determined by means of ion-exchange chromatography in 16 previously untreated patients with generalized idiopathic epilepsy and in some of their first-degree relatives (26 subjects), and the results were compared with those obtained from a group of 50 healthy controls. The patients were subsequently treated with valproic acid for one month and then reexamined. In the epileptic subjects, statistical analysis showed significant alterations in the plasma levels of a group of amino acids, including the four associated with neuro-transmission (aspartate, glutamate, glycine, taurine); aspartate, glutamate and glycine levels were also altered in the first-degree relatives. Valproic acid therapy did not affect amino acid levels. If further confirmed, these alterations might be considered possible neurochemical markers of epilepsy.

Abstract
Sixty-three patients with autonomous thyroid nodule were studied, thirty-five from an endemic goiter area (EA) and twenty-eight from a non-endemic goiter area (NEA). Clinical history, physical examination, ultrasonography, thyroid hormone levels, and fine needle aspiration (FNA), were utilized to investigate whether or not iodine deficiency determined differences in the latency of progression to toxicity, the seriousness of illness and thyroid hormone levels. No significant difference was observed in the age of onset of nodularity, while the latency of progression to toxicity was significantly decreased in the EA (p less than 0.001). The ultrasonographic pattern did not show significant volume variations between the EA and NEA, but there was a slight prevalence of multinodular lesions in EA. No significant difference in serum thyroid hormone levels was found between the two areas in non toxic patients, while at the onset of hyperthyroidism higher levels of FT were observed in the EA than in the NEA. FNA showed a prevalence of colloid lesions in EA, while hyperplastic lesions prevail in the NEA. Forty-two patients underwent surgery: the extent of surgery was greater in patients from the EA. In conclusion, in iodine deficient areas earlier clinical thyrotoxicosis and a higher prevalence of hypoactive thyroid nodules were observed. Furthermore, in EA, the autonomous nodule in non toxic phase is more frequently associated with colloid lesions than hyperplastic lesions.

Abstract
This study evaluated a new, simple, disposable visual measuring device (AccuLevel), which uses enzyme immunochromatography to indicate visually, without any instrument, the concentrations of three major antiepileptic drugs (AEDs) in small blood samples. Drug levels (30 values for diphenylhydantoin, 41 for phenobarbital, and 40 for carbamazepine) obtained by AccuLevel were compared with those obtained with the enzyme-multiplied immunoassay technique (EMIT). Results showed an excellent correlation between EMIT and AccuLevel data for the three major AEDs. The method appears to be particularly suitable in outpatients and in case of emergency.

Abstract
The tolerability and pharmacokinetics of a new controlled-release (CR) formulation of carbamazepine (CBZ), were assessed in a multicentre, double-blind, cross-over trial, carried out in 48 epileptic patients (21 men, 27 women; mean age 34.2 years) on conventional CBZ monotherapy, but without complete seizure control (n = 22) or with intermittent side effects (n = 4), or with both (n = 22). Eligible patients were randomized to conventional CBZ or CR CBZ, each given in sequence at individualized daily doses, subdivided into the lowest number of administrations. Each period of the cross-over consisted of a first phase of optimal dose finding (lasting up to two months) and a second one of maintenance (lasting one month) used for evaluation. At the end of each period, a 10-h plasma CBZ and CBZ-epoxide concentration profile, as well as the tolerability and the efficacy of the drugs, were evaluated. The mean CBZ daily dose increased by 16% during the administration of the CR formulation. Fluctuations of total CBZ and 10, 11-epoxide plasma level daily profiles at steady-state were significantly (p less than 0.001) lower during CR CBZ treatment, leading to a significant (p less than 0.001) decrease in intermittent side effects (6 patients on CR CBZ vs 26 on conventional CBZ). Finally, 38 patients on CR CBZ (vs 15 patients on conventional CBZ) were treated with a b.i.d. regimen.

Abstract
A 24-year-old woman was admitted to hospital because of hirsutism, virilism and amenorrhea, which had appeared 6 months earlier. Endocrinological evaluation showed a slightly elevated serum level of testosterone (1.2 +/- 0.05 ng/ml), normal plasma levels of dehydroepiandrosteronesulfate (DHEA-S) (2,070 +/- 6 ng/ml), androstenedione (1.8 +/- 0.5 ng/ml) and sex hormone-binding globulin (SHBG)(42 +/- 3 nM/L); there was normal urinary 17-ketosteroid (17-KS) excretion (11.7 mg/24 h), low urinary estrogen (E) excretion (3 +/- 0.4 micrograms/24 h), suppressed basal gonadotropin concentrations (LH 0.9 microUI/ml; FSH 3.2 microUI/ml) and an exaggerated response to the LH-RH test. At laparotomy, a monolateral ovarian tumor was found, which was proved histologically to be a Sertoli-Leydig cell tumor. After tumor ablation, a regular menstrual cycle followed and progressive reduction of virilism was noted. This was followed within 4 months by complete normalization of LH, FSH, estrogen and progesterone serum levels. The responsiveness to LH-RH also became normalized. Two years after this operation, the patient had a normal pregnancy. This case of virilization in a woman affected by a benign Sertoli-Leydig cell tumor was primarily characterized by an unusual response of the hypothalamopituitary axis against an endocrinological background of notable alteration of the androgen/estrogen ratio, where the androgens were slightly increased and the estrogens greatly reduced.

Abstract
After intravenous (i.v.) administration (10 mg/kg), the biodisposition of phenytoin (PHT) in serum (total and free concentration), cerebrospinal fluid (CSF), brain, and the interstitial fluid (IF) of the normal brain were determined in dogs. A sufficient volume of IF was obtained through a multiperforated polypropylene ball implanted into the left parietotemporal region for 4-5 weeks. PHT brain distribution coefficient values ranged between 1.9 and 3.75, while the ratios of IF to free serum PHT concentrations ranged between 0.19 and 1.04; thus, our data indicate that most of the free unbound PHT which enters the brain parenchyma accumulates in the cellular compartment. Furthermore, at 60 and 90 min the peak CSF and IF concentrations are delayed; thus, for PHT, an apparent diffusion front from the CSF into the extracellular space of the brain seems to occur.

Abstract
Three groups of women were evaluated for TSH response to TRH and for goiter morphology by means of thyroid ultrasonography: group A = goitrous nonsmokers; group B1 = goitrous moderate-smokers; group B2 = goitrous heavy-smokers. They were compared with a control group (group C) made up nongoitrous, nonsmoking women. The size of the goiter was not correlated with the daily consumption of cigarettes, even though in heavy smokers a nodular goiter was prevalent as shown by ultrasonography. The serum values of TT3 showed significant differences between nonsmokers and heavy smokers (p less than (p less than 0.005), whereas the serum values of TT4 and of basal TSH showed no statistically significant differences. On the contrary, the TSH response to TRH showed a significant difference between heavy and nonsmokers (p less than 0.05). In conclusion, it has been demonstrated that goitrous cigarette heavy smokers show: i) A prevalence of statistically significant nodular goiter; ii) A significantly higher TT3 serum levels; iii) A significantly higher re-of TSH to TRH. These data suggest that cigarette smoking favors the development of nodular goiter and can involve the central regulation of the hypothalamus-pituitary-thyroid interaction.

Abstract
The interaction between the carbohydrate and the amino acid residues in human thyroglobulin has been studied. Previous reports showed that the removal of the two terminal carbohydrates of the complex chains leads to an increase in thyroglobulin binding to thyroid membranes. In our study, after enzymatic release with glycosidases of the sugar moieties from thyroglobulin, a time-dependent decrease in tryptophan fluorescence has been observed. This decrease was also associated with a shift in the emission peak from 335 to 340 nm. The strong quenching of tryptophan emission was also accompanied by a decrease in the exposure of tryptophan residues, as shown by a Stern-Volmer analysis with the neutral quencher acrylamide. These data, together with the increase in fluorescence of the dansylated deglycosylated thyroglobulin, strongly suggest that a significant conformational change of thyroglobulin follows the deglycosylation of the protein.
