Abstract
Autoimmune neuromuscular diseases are a group of heterogenous pathologies secondary to the activation of the immune system that damage the structures of the peripheric nerve, the neuromuscular junction, or the skeleton muscle. The diagnosis of autoimmune neuromuscular disorders comprises a combination of data from clinical, laboratory, electromyography, imaging exam, and biopsy. Particularly, the whole-body MRI examination in the last two decades has been of great use in the assessment of neuromuscular disorders. MRI provides information about the structures involved and the status of activity of the disease. It can also be used as a biomarker, detect the pattern of specific muscle involvement, and is a useful tool for targeting the optimal muscle site for biopsy. In this work, we summarized the most used technical protocol of whole-body MRI and the role of this imaging technique in autoimmune neuromuscular disorders.

Abstract
Background The newly adopted European directive DE59/2013 mandates adequate patient information in procedures involving ionising radiation. Patient interest in knowing about their radiation dose and an effective communication method for dose exposure remain poorly investigated. Purpose This study is aimed at investigating both patient interest in radiation dose and an effective method to communicate radiation dose exposure. Material and methods The present analysis is based on a multi-centre cross-sectional data collection involving 1,084 patients from four different hospitals ‒ two general and two paediatric hospitals. Anonymous questionnaires were administered, consisting of an initial overview of radiation use in imaging procedures, a patient data section, and an explanatory section providing information in four modalities. Results 1009 patients were included in the analysis, with 75 refusing participation; 173 participants were relatives of paediatric patients. Initial information provided to patients was considered comprehensible. The information modality with symbols was considered the most readily understandable format by patients, with no appreciable differences in comprehension attributable to social or cultural background. The modality including dose numbers and diagnostic reference levels was preferred by patients with higher socio-economic background. The option 'None of those' was selected by one-third of our sample population, composed of four different clusters: female, over 60 years old, unemployed, and from low socio-economic backgrounds. Conclusions This study demonstrated a high level of interest amongst patients in knowing about radiation dose exposure. Pictorial representations were well understood by patients from a variety of different ages and education levels. However, a universally comprehensible model of communicating radiation dose information remains to be elucidated.

Abstract
Although certain individuals with HIV infection can stop antiretroviral therapy (ART) without viral load rebound, the mechanisms under-pinning 'post-treatment control' remain unclear. Using RNA-Seq we explored CD4 T cell gene expression to identify evidence of a mechanism that might underpin virological rebound and lead to discovery of associated biomarkers. Fourteen female participants who received 12 months of ART starting from primary HIV infection were sampled at the time of stopping therapy. Two analysis methods (Differential Gene Expression with Gene Set Enrichment Analysis, and Weighted Gene Co-expression Network Analysis) were employed to interrogate CD4+ T cell gene expression data and study pathways enriched in post-treatment controllers versus early rebounders. Using independent analysis tools, expression of genes associated with type I interferon responses were associated with a delayed time to viral rebound following treatment interruption (TI). Expression of four genes identified by Cox-Lasso (ISG15, XAF1, TRIM25 and USP18) was converted to a Risk Score, which associated with rebound (p < 0.01). These data link transcriptomic signatures associated with innate immunity with control following stopping ART. The results from this small sample need to be confirmed in larger trials, but could help define strategies for new therapies and identify new biomarkers for remission.

Abstract
Twenty-one patients with metastatic prostate cancer who had become refractory to hormonal therapies received lonidamine (150 mg tid and 600 mg daily dose in 17 and 4 patients, respectively). In all but 4 patients, treatment was continued until disease progression or the development of severe toxicity. Toxicity was minimal and reversible (score 1 or 2) and included myalgia (8 cases), arthralgia (6 cases), gastrointestinal toxicity (11 cases), fatigue (14 cases) and testicular pain (9 cases). The response was evaluated after at least one month of therapy with lonidamine, according to NPCP-USA recommendations. Of 21 patients who entered the study, only 15 were evaluable for response; 2 died (1 for severe toxicity and 1 for drug-unrelated reasons). No objective response was obtained in the series. In fact, only 6 patients achieved stable disease and 9 progressed. Median survival time from the beginning of treatment was no longer than that of patients in a similar condition who were treated with standard palliative maneuvers. We conclude that this therapeutic approach with lonidamine is not active in hormone-refractory prostatic cancer patients with distant metastasis.

Abstract
Eight factors were analyzed for prognostic significance in univariate analyses in a series of 76 women with stage IV ovarian carcinoma treated with combination chemotherapies including cisplatin or carboplatin. The clinical objective and pathologic complete response rates were 51.2% and 27.3%, respectively. Median overall survival and progression-free survival were 15 and 7 months, respectively. No variables reached statistical significance. Trends toward better survival were noted for grades 1 and 2 for the adriamycin-containing regimen. Using progression-free survival as an end point, significant prognostic factors included complete clinical or pathologic response. Our data confirm that the standard approach is unlikely to modify the clinical outcome of stage IV ovarian cancer. New treatment modalities including high-dose-intensity regimens and neo-adjuvant chemotherapy delivered before surgery could improve clinical results. Moreover, biologic characterization of ovarian tumors may provide information to design specifically targeted treatment.

Abstract
OBJECTIVES Antiretroviral therapy (ART) during acute HIV infection (AHI) restricts the HIV reservoir, but additional interventions are necessary to induce a cure. Intravenous immunoglobulin (IVIG) is not HIV-specific but is safe and temporarily reduces the HIV reservoir in chronic HIV infection. We present a randomized controlled trial to investigate whether IVIG plus ART in AHI reduces the HIV reservoir and immune activation compared with ART alone. METHODS Ten men with AHI (Fiebig II-IV) initiated ART (tenofovir, entricitabine, ritonavir boosted darunavir and raltegravir) at HIV-1 diagnosis and were randomized to ART alone or ART plus 5 days of IVIG, once virally suppressed (week 19). Blood samples were evaluated for viral reservoir, immune activation, immune exhaustion and microbial translocation. Flexible sigmoidoscopy was performed at weeks 19, 24 and 48, and gut proviral DNA and cell numbers determined. RESULTS IVIG was well tolerated and no viral blips (> 50 HIV-1 RNA copies/mL) occurred during IVIG therapy. From baseline to week 48, total HIV DNA in peripheral blood mononuclear cells (PBMCs) (cases: -3.7 log10 copies/106 CD4 cells; controls: -3.87 log10 copies/106 CD4 cells) declined with no differences observed between the groups (P = 0.49). Declines were observed in both groups from week 19 to week 48 in total HIV DNA in PBMCs (P = 0.38), serum low copy RNA (P = 0.57) and gut total HIV DNA (P = 0.55), but again there were no significant differences between arms. Biomarkers of immune activation, immune exhaustion and microbial translocation and the CD4:CD8 ratio were similar between arms for all comparisons. CONCLUSIONS Although safe, IVIG in AHI did not impact total HIV DNA, immune function or microbial translocation in peripheral blood or gut tissue.

Abstract
Probiotics are becoming increasingly important in basic and clinical research, but they are also a subject of considerable economic interest due to their expanding popularity. They are live micro-organisms which, when administered in adequate amounts, confer a health benefit to the host. From this very well-known definition, it is clear that, unlike drugs, probiotics might be useful in healthy subjects to reduce the risk of developing certain diseases or to optimise some physiological functions. They also may offer some advantages in already ill persons in relieving symptoms and signs, e.g. people with acute diarrhea. According to current definitions, probiotics should survive both gastric acid and bile to reach the small intestine and colon, where they exert their effects. Many of these are available in a lyophilized (freeze-dried) pill form, though some are available in yogurt or as packets (sachets), which can be mixed into non-carbonated drinks. The present review focuses on three main issues: 1) understanding why, at present, probiotics are so interesting for doctors and consumers; 2) reviewing the available data on probiotic use in digestive diseases, in particular irritable bowel syndrome (IBS), (prevention of) infectious diarrhea, inflammatory bowel disease (IBD), non-alcoholic fatty liver disease (NAFLD), and colorectal cancer (CRC); 3) highlighting the individual profile of Lactobacillus GG (LGG) in the above contexts, providing an assessment as well as recommendations on its use in gastro-intestinal tract (GIT) disorders. Research studies conducted in animals and humans with the main probiotics strains for GIT diseases, and published from the early 1990s to 2014 have been considered. PubMed, Medline and Ovid were the main sources adopted for data retrieving. The increasing attention on probiotics is a direct consequence of the improvement in the techniques for studying microbiota. Until recently, its composition has been analysed by culture-based methods that use differential media to select for specific populations of bacteria according to their metabolic requirements. Lactobacillus and Bifidobacterium species are by and large the most commonly used probiotics. Strictly speaking, however, the term "probiotic" should be reserved for live microbes that have been shown in controlled human studies to provide a health benefit. Taking into account patients suffering from the most common gastrointestinal diseases, in whose establishment the GI microbiota plays a key role, probiotics have to be considered as very promising agents, capable of beneficially modulating the intestinal ecosystem, which is perturbed in cases of dysbiosis. Although more clinical data are still needed to better assess the clinical relevance of probiotics, to date, procariota such as Bifidobacteria and Lactobacilli strains, and eucariota such as some Saccharomyces strains are among the most widely used agents in GIT disorders. LGG is a well-known probiotic strain that was isolated more than 20 years ago by Goldin and Gorbach from a faecal sample of a healthy adult, based on several selection criteria: high adhesion in vitro, high resistance against gastric acidity and high antimicrobial activity against pathogens such as Salmonella. In vivo studies have also shown a good persistence of LGG in the human GIT. Since its isolation, LGG has become one of the best clinically documented probiotic strains. A growing body of evidence suggests benefits such as prevention and relief of various types of diarrhoea, and treatment of relapsing Clostridium difficile colitis. Thus, with respect to both adaptation to the GIT and probiotic effects, LGG can be regarded as a prototypical probiotic strain.

Abstract
Multiple sclerosis (MS) is thought to be an autoimmune T-cell-mediated disease directed at myelin antigens of the central nervous system. Besides myelin proteins, lipid components of CNS are supposed to play a role as antigens for T cells in MS. CD1 is a family of MHC-like glycoproteins specialized in capturing and presenting a variety of microbial and self lipids and glycolipids to antigen-specific T cells. CD1-restricted T cells specific for gangliosides and sulfatide have been isolated from subjects with MS and in mice with experimental allergic encephalopathy. We genotyped exon 2 of CD1A and CD1E in 205 MS patients and 223 unrelated healthy controls and determined their association with the presence of anti-ganglioside and anti-sulfatide antibodies. CD1E 01-01 is associated with a reduced risk of MS (OR 0.54, p=0.001); CD1A 02-02 (OR 1.99, p=0.012) or CD1E 02-02 (OR 2.45, p=0.000) with an increased risk. The combination of the genotypes CD1A 02-02 and CD1E 02-02 is present in 90.7% of patients but in only 9.4% controls (OR 94.16, p= 0.000). CD1A and CD1E polymorphisms contribute to the polygenic susceptibility to MS. The functional effects of CD1 polymorphisms are unknown, however changes in CD1 alleles may affect numerous immunological functions.

Abstract
A primary angiosarcoma was found in the tongue of a six-week-old female Wistar rat, sacrificed for humane reasons during the course of a four-week toxicology study. At necropsy, a nodule protruding from the dorsal part of the tongue was found. The nodule displayed microscopically, irregularly shaped vascular spaces separated by collagenous stroma. The spindle-shaped endothelial cells showed pleomorphism, hyperchromatism, and low mitotic activity; large nuclei with one or more nucleoli were present. Multiple metastases were found in the lungs, and the morphology of the cells resembled that of the primary tumor. Immunohistochemically, the primary tumor and the lung metastases were positive for von Willebrand factor and vimentin. The diagnosis of tongue angiosarcoma metastasizing to the lungs was made on the basis of microscopic and immunohistochemical findings.

Abstract
Preparations of thiol"protein disulfide oxidoreductase from bovine liver were shown to be homogeneous by polyacrylamide gel electrophoresis, sedimentation equilibrium centrifugation and NH2-terminal analysis (Carmichael et al., 1977). When the enzyme was subjected to prolonged storage at -20 degrees, freeze-thawing, or heating at 60 degrees, at least one new protein species was observed using polyacrylamide gel electrophoresis. The new protein results from dimerization of the enzyme. The dmier consisted of two monomers held together by an intermolecular disulfide bond. The formation of this dimer can be reversed and partially prevented by thiols.

Abstract
A common post-traumatic location of epileptogenesis is the medial temporal lobe despite evidence of associated diffuse or remote cerebral injury. We undertook a review of post-traumatic medial temporal lobe epilepsy (MTLE) patients as part of an overall post-traumatic epilepsy population to assess the extent of cerebral injury sustained by this subpopulation and to establish whether surgical outcome differed from that of a non-traumatically-induced epilepsy population. A retrospective review of 57 patients operated for post-traumatic epilepsy (PTE) over a 10-year period (1993-2003) was undertaken with particular attention to those undergoing medial temporal resection. Preoperative magnetic resonance imaging (MRI) was assessed for the type and location of abnormalities. Postoperative outcomes were compared with those of patients with MTLE of non-traumatic origin operated by the same surgeon. Of the 57 patients operated, 30 cases underwent medial temporal lobe resection. The most common mechanism of injury was blunt trauma attributable to motor vehicle accidents with imaging abnormalities characterized by medial temporal sclerosis (MTS; 16 cases), T2/FLAIR hyperintensities (nine cases), periventricular gliosis (seven cases), diffuse cerebral atrophy (five cases) and focal encephalomalacia (three cases). Six patients had normal MRI studies. No significant differences in postoperative outcomes were found between post- and non-traumatic MTLE epilepsy groups. The presence of histopathological change in the medial temporal lobe varied greatly and provided no indication of a favourable postoperative outcome. Patients with post-traumatic medial temporal lobe epilepsy respond favourably to surgical treatment. In the case of medial temporal sclerosis, there is substantial variation of histopathological findings which correlate poorly with current imaging applications. The favourable outcomes obtained following surgery in this group attest to a commonality with other risk factors in the genesis of epilepsy in this location.

Abstract
The erythrocyte is a cell highly exposed to oxygen pressure that, in turn, provokes oxidative stress involving loss of SH-groups, cell shrinkage by activation of K(+)-Cl(-) cotransport (KCC) and membrane destabilization which plays an important role in the premature haemolysis of red blood cells (RBCs). Oxidative stress provoked by chemicals frequently occurs in human erythrocytes. The aim of this study was to test whether the antibiotics alter the redox state and investigate their influences on band 3 protein that is involved in the facilitated electro neutral exchange of Cl(-) for HCO(3)(-) across the membrane of mammalian erythrocytes. Normal erythrocytes were treated with some antibiotics and thiol oxidizing agent N-ethylmaleimide (NEM) and tested for sulphate uptake, K(+) efflux and for glutathione (GSH) concentration as an index of oxidative stress. The rate constant of SO(4)(=) uptake measured in erythrocytes treated with antibiotics as well as NEM was decreased with respect to control cells as a result of band 3 SH-groups oxidation or the stress-induced K(+)-Cl(-) symport-mediated cell shrinkage. In fact, this hypothesis was verified by increased K(+) efflux and decreased GSH values measured in treated erythrocytes compared to controls.

Abstract
The L-PAM-ILP procedures under true hyperthermal regime (41.5-41.8 degrees C) require both close control of the physical parameters of the treatment (temperatures profiles and time duration, artero-venous pressure, perfusate flow rate) and medical rationale (drug, dosage, fractioning, timing). All the above essential procedures must be supported by rigorous methodology, reliable operation of the medical devices and apparatus and real-time monitoring of the treatment parameters. Real-time monitoring is essential for proper trimming and modulation of the parameters during treatment. This paper delineates the technical improvements that we have implemented for drug leakage monitoring and control in the systemic circulation aimed at improving the therapeutic efficacy and at reducing the occurrence of unexpected complications.

Abstract
The argument of the iatrogenic side effects of pharmacological origin that can cause ototoxic effects or only disacustic symptoms like the tinnitus, without consequent degenerative effects, is enlarged in these last years. It is because of the great knowledge based on the careful attention from the pharmaceutical institutions which are responsible for the control of medicines and drugs. In the medical practice and in that specialty field born the need to gather, also in consideration of the possible medico-legal implications, those elements which will suppose the risk of otologic side effects. This will allow the physicians to evaluate the possible clinical advantage of a treatment, in their own field of competence, balancing them with their possible side effects in the otologic field. For this purpose, we have elaborated some updated lists of drugs with possible side effects of ototoxicity, tinnitus and vertigo; furthermore, we considered these drugs as could theoretically have influence on the auditory neurochemical progressing since they have excitatory or inhibitory action on the neurotransmitters and their receptors, but not signaled by the sources of institutional information.

Abstract
Isolated locoregional limbs perfusion treatments of various malignancies have demonstrated synergistic efficacy when hyperthermia was associated with chemotherapy. This paper delineates the criteria, the technical provisions and the specifications that have been improved and implemented at our Institution. It is believed that, following the indications offered in this paper, several, apparently still unsolved problems of treatment planning and implementation will be overcome, offering closely controlled and highly reproducible procedures with a significant progress in the feasibility of reliable comparisons of the results among different research centres and in the reduction of the occurrence of controversial results or unexpected complications.

Abstract
Polyphenol oxidase (PPO) was isolated from the B-serum obtained after repetitive freeze-thawing of the bottom fraction isolated from ultracentrifuged fresh latex. The B-serum was subjected to acetone precipitation and CM-Sepharose chromatography, affording two PPOs, PPO-I and PPO-II, which, upon SDS-PAGE, were 32 and 34 kDa, respectively. Both PPOs possessed the same pI (9.2), optimum pH (7) and optimum temperature (35-45 degrees C). They are stable up to 60 degrees C and active at broad pH ranges from 4-9. The K(m) values of PPO-I for dopamine, L-dopa and catechol as substrates are 2.08, 8.33 and 9.09 mM, while those for PPO-II are 2.12, 4.76 and 7.14 mM, respectively. Among various PPO inhibitors tested, 4-hexylresorcinol was the most potent. Anionic detergents were among the most effective activators of the enzymes, while cationic and nonionic detergents showed little and no effect on the PPO activities, respectively.

Abstract
Recent evidence suggests that a CD8-mediated cytotoxic T cell response against the Tat protein of human immunodeficiency virus (HIV)/simian immunodeficiency virus (SIV) controls primary infection after pathogenic virus challenge, and correlates with the status of long-term nonprogressor in humans. Due to the presence of unmethylated CpG sequences, DNA vaccination can boost the innate immunity driving more potent T cell-mediated immune responses. Therefore, cynomolgus monkeys were vaccinated with a tat-expressing vector containing defined unmethylated CpG sequences (pCV-tat). Here it is shown that the intramuscular inoculation of the pCV-tat contained primary infection with the highly pathogenic SHIV89.6P virus preventing the CD4(+) T cell decline in all the vaccinated monkeys. Undetectable virus replication and negative virus isolation correlated in all cases with the presence of anti-Tat CTLs. However, a CD8-mediated non cytolytic antiviral activity was also present in all protected animals. Of note, this activity was absent in the controls but was present in the monkey inoculated with the CpG-rich vector alone that was partially protected against viral challenge (i.e. no virus replication but positive virus isolation). These results suggest that a CTL response against Tat protects against primary infection by blocking virus replication at its early stage, in the absence of sterilizing immunity. Nevertheless, the boost of the innate immunity by CpG sequences can contribute to this protection both by driving more potent CTL responses and by inducing other CD8-mediated antiviral activities. Thus, the CpG-rich tat DNA vaccine may represent a promising candidate for preventive and therapeutic vaccination against AIDS.

Abstract
Here we describe a procedure for cloning pigs by the use of in vitro culture systems. Four healthy male piglets from two litters were born following nuclear transfer of cultured somatic cells and subsequent embryo transfer. The initiation of five additional pregnancies demonstrates the reproducibility of this procedure. Its important features include extended in vitro culture of fetal cells preceding nuclear transfer, as well as in vitro maturation and activation of oocytes and in vitro embryo culture. The cell culture and nuclear transfer techniques described here should allow the use of genetic modification procedures to produce tissues and organs from cloned pigs with reduced immunogenicity for use in xenotransplantation.

Abstract
The Tat protein of human immunodeficiency virus (HIV) is produced very early after infection, plays a key role in the virus life cycle and in acquired immunodeficiency syndrome (AIDS) pathogenesis, is immunogenic and well conserved among all virus clades. Notably, a Tat-specific immune response correlates with non-progression to AIDS. Here, we show that a vaccine based on the Tat protein of HIV blocks primary infection with the simian/human immunodeficiency virus (SHIV)89.6P and prevents the CD4 T cell decline and disease onset in cynomolgus monkeys. No signs of virus replication were found in five out of seven vaccinated macaques for almost 1 year of follow-up. Since the inoculated virus (derived from rhesus or from cynomolgus macaques) is shown to be highly pathogenic in cynomolgus macaques, the results indicate efficacy of Tat vaccination in protection against highly pathogenic virus challenge. Finally, the studies of the Tat-specific immunological responses indicate a correlation of protection with a cytotoxic T cell response. Thus, a Tat-based vaccine is a promising candidate for preventive and therapeutic vaccination in humans.

Abstract
BACKGROUND We report the experience of the World Health Organization (WHO) Melanoma Program concerning sentinel lymph node (SLN) biopsy for detecting patients with occult regional nodal metastases to submit to selective regional node dissection. METHODS From February 1994 to August 1998, in 12 centers of the WHO Melanoma Program, 892 SLN biopsies were performed in 829 patients with clinical stage I melanoma (male: 370; female: 459; median age: 50 years old). The location of the primary melanoma was as follows: trunk 35%; lower limbs, 45%; upper limbs, 18%; and head and neck, 2%. Blue dye injection for SLN identification was performed in all cases; preoperative lymphoscintigraphy was done in 440 patients, and an intra-operative probe for a radio-guided biopsy was used in 141 cases. Overall, the SLN identification rate was 88%. In 68% of the patients, only one SLN was identified, whereas two and three or more SLN were detected in 24% and 8% of the remaining cases, respectively. RESULTS Overall SLN positivity rate was 18%. Intra-operative frozen section examination was performed in 39% of the cases and was helpful in detecting occult localizations only in 47% of the positive SLNs. Distribution of positive cases by primary thickness was as follows: < 1mm: 2%; 1-1.99 mm: 7%; 2-2.99 mm: 13%; and > or = 3 mm: 31%. Positive nonsentinel lymph nodes were found in 22% of cases with positive SLN submitted for selective dissection. No complications due to the procedure were registered. Of 710 patients who were evaluated, 40 (6%) presented a regional nodal relapse after a negative SLN biopsy and underwent a delayed therapeutic dissection. From the 710 enrolled cases, 638 (88.5%) were alive without evidence of disease at the time of this writing. A multivariate analysis showed SLN status as one of the most significant prognostic factors (P = .000) along with thickness (P = .001) and ulceration (P = .015) of primary tumor. CONCLUSIONS These data confirm the feasibility and safety of the SLN technique for selecting patients to submit to a radical node dissection. The data represent the basis for a future trial by the WHO Melanoma Program in this field to evaluate the most appropriate surgical approach for treating patients with occult regional nodal metastases.

Abstract
The French Radiotherapy-Oncology Society (SFRO) and the National Trade of Radiotherapists-Oncologists (SNRO) elaborated and published a patient information booklet on radiotherapy, in 1999. This present study appraises the pertinence of the form and substance of this booklet one year after its release. Eight radiotherapy centers participated in this research which evaluated 162 patients at treatment initiation. The conclusions of this study demonstrated the importance of clearly informing patients of their disease, treatment, and the secondary effects of treatment. It is essential to emphasize that 97% of the patients declared that an information booklet is a real necessity, and that the one provided by the SFRO responds to the majority of their concerns. Obtaining technical and practical knowledge resulted in a reassurance about their treatment. The most revealing result is that 87% requested direct communication about their illness, and that cancer be named by this word and not other, evasive terms. Seventy-two percent of the patients requested more information about their cancer, different treatment options, and quality of life issues in an attempt to psychologically prepare themselves to face an illness for which they have little control. Patients refuse to be passive, and claim the right to become 'partners' of the medical teams, concerning their treatment and recovery.

Abstract
BACKGROUND/AIMS The purpose of this study was to better define the long term prognosis of infection and disease in children with chronic hepatitis B treated with interferon (IFN) alpha. PATIENTS A total of 107 children with chronic hepatitis B who received IFN alpha for three or six months in two clinical trials were followed for a mean period of 69 (17) months. Response to treatment was defined as loss of hepatitis B e antigen (HBeAg) within 12 months after stopping treatment. A control group of 59 patients was also followed for a shorter mean time (46 (19) months). RESULTS Sixteen (15%) treated children responded during therapy and 18 (17%) during post-treatment follow up; 31 (29%) non-responders lost HBeAg during subsequent years. High pretreatment levels of transaminases and a greater histological activity index were predictors of response. Kaplan-Meier estimates of cumulative HBeAg clearance rates at five years were similar between treated patients (60%) and controls (65%). After HBeAg clearance, all cases lost hepatitis B virus DNA and 94% had normal transaminase levels. Loss of hepatitis B surface antigen (HBsAg) occurred in four (25%) patients who responded during treatment but in none of the other treated or untreated patients. CONCLUSIONS After five years' observation, the proportion of treated children with sustained HBeAg clearance comprised an equal number of responders and non-responders and did not differ from that observed in untreated controls, suggesting that IFN simply accelerated a spontaneous event. However, IFN significantly improved the rate of HBsAg loss in cases with more prominent disease activity who were early responders, and may be particularly useful in this type of patient.

Abstract
OBJECTIVE The purpose of this study was to investigate the effects of fluoxetine (F) and indomethacine (I), two drugs that regulate the synthesis of the GABAergic neurosteroid 3 alpha, 5 alpha tetrahydroprogesterone (allopregnanolone, THP) on THP plasma levels and on symptoms of anxiety and depression in alcoholics during ethanol withdrawal. METHOD Patients who met DSM-IV criteria for alcohol abuse were randomly assigned to treatment with F (40 mg/day) plus misoprostol (M) (500 mg/day) or I (100 mg/day) plus M or placebo (PL) plus M. Patients were rated with the Hamilton Anxiety (14-HAS) and Depression (17-HDS) scales on days 1, 5, 7, 15 and 28 of ethanol withdrawal and with a Visual Analogue Scale for Depression (VASD) and a Visual Analogue Scale for Anxiety (VASA) on days 1, 2, 4, 5, 7, 15 and 28 of withdrawal. On the same days a plasma sample was collected to measure the concentrations of THP by means of a very sensitive gas chromatographic mass spectrometric method. RESULTS During withdrawal at days 1, 2, 4 and 5, THP plasma values were lower and symptoms of anxiety and depression were significantly higher compared to the late withdrawal phase at days 15 and 28. In the F or I treatment, the depression and anxiety score, measured by VASD and VASA, decreased significantly at day 5-7 whereas THP plasma levels significantly increased compared to PL condition CONCLUSIONS Treatment of alcohol withdrawal either with F or I reduced the extent of anxiety and depression and normalised THP plasma levels that were decreased during withdrawal.
