Prognostic significance of the bcl-2 apoptotic family of proteins in primary and recurrent cervical cancer. bcl-2 is one of a family of genes that control the apoptotic threshold of a cell. bcl-2 protein and its anti-apoptotic homologue, mcl-1, with the pro-apoptotic protein, bax, are thought to function by forming homo- and heterotypic dimers that then control the progression to apoptosis. p53 is also involved as a down-regulator of bcl-2 and a promoter of bax. To determine the effect of these apoptotic mechanisms, we used immunohistochemistry to determine the prognostic significance of the expression of bcl-2, mcl-1, bax and p53 in primary and recurrent cervical cancer. Tissues from 46 patients with primary cervical cancer and 28 women with recurrent carcinoma were stained for bcl-2, mcl-1, bax and p53. Kaplan-Meier survival analysis was performed using the log-rank test for differences between groups. In the primary disease group, positive staining for bcl-2 was associated with a better 5-year survival (bcl-2 +ve, 84% vs bcl-2 -ve, 53%, P = 0.03). Positive staining for p53 was associated with a survival disadvantage (p53 +ve, 4-year survival 38% vs p53 -ve, 4-year survival 78%, P = 0.02). mcl-1 and bax staining were not useful as prognostic indicators in primary disease. No marker was prognostic in recurrent disease. Positive bcl-2 staining defines a group of patients with primary disease with a good prognosis. p53, an activator of the bax promoter, identifies a group with a worse outcome. In recurrent disease, none of the markers reflected prognosis.

Hyperthermia effects on the cytoskeleton and on cell morphology. Human erythrocyte ghost membranes undergo five thermal transitions at temperatures between 50 and 75 degrees C.

Such patients are at high risk of serious exacerbations and asthma-related mortality. METHODS: Here, we pooled data from seven studies to determine the effect of omalizumab, an anti-immunoglobulin E (IgE) monoclonal antibody, on asthma exacerbations in patients with severe persistent asthma. Omalizumab was added to current asthma therapy and compared with placebo (in five double-blind studies) or with current asthma therapy alone (in two open-label studies). The studies included 4308 patients (2511 treated with omalizumab), 93% of whom had severe persistent asthma according to the Global Initiative for Asthma (GINA) 2002 classification. Using the Poisson regression model, results were calculated as the ratio of treatment effect (omalizumab : control) on the standardized exacerbation rate per year. RESULTS: Omalizumab significantly reduced the rate of asthma exacerbations by 38% (P < 0.0001 vs control) and the rate of total emergency visits by 47% (P < 0.0001 vs control). Analysis of demographic subgroups showed that the efficacy of omalizumab on asthma exacerbations was unaffected by patient age, gender, baseline serum IgE (split by median) or by 2- or 4-weekly dosing schedule, although benefit in absolute terms appeared to be greatest in patients with more severe asthma, defined by a lower value of percentage predicted forced expiratory volume in 1 s (FEV(1)) at baseline. CONCLUSIONS: These results suggest that omalizumab may fulfil an important need in patients with severe persistent asthma, many of whom are not adequately controlled on current therapy." ], "offsets": [ [ 159, 1930 ] ] } ]

The effect of treatment with omalizumab, an anti-IgE antibody, on asthma exacerbations and emergency medical visits in patients with severe persistent asthma. BACKGROUND: Patients with severe persistent asthma who are inadequately controlled despite treatment according to current asthma management guidelines have a significant unmet medical need. Such patients are at high risk of serious exacerbations and asthma-related mortality. METHODS: Here, we pooled data from seven studies to determine the effect of omalizumab, an anti-immunoglobulin E (IgE) monoclonal antibody, on asthma exacerbations in patients with severe persistent asthma. Omalizumab was added to current asthma therapy and compared with placebo (in five double-blind studies) or with current asthma therapy alone (in two open-label studies). The studies included 4308 patients (2511 treated with omalizumab), 93% of whom had severe persistent asthma according to the Global Initiative for Asthma (GINA) 2002 classification. Using the Poisson regression model, results were calculated as the ratio of treatment effect (omalizumab : control) on the standardized exacerbation rate per year. RESULTS: Omalizumab significantly reduced the rate of asthma exacerbations by 38% (P < 0.0001 vs control) and the rate of total emergency visits by 47% (P < 0.0001 vs control). Analysis of demographic subgroups showed that the efficacy of omalizumab on asthma exacerbations was unaffected by patient age, gender, baseline serum IgE (split by median) or by 2- or 4-weekly dosing schedule, although benefit in absolute terms appeared to be greatest in patients with more severe asthma, defined by a lower value of percentage predicted forced expiratory volume in 1 s (FEV(1)) at baseline. CONCLUSIONS: These results suggest that omalizumab may fulfil an important need in patients with severe persistent asthma, many of whom are not adequately controlled on current therapy.

[Binding sites for 3H-Leu-enkephalin in rat straitum]. The binding of 3H-Leu-Enkephalin to a particulate fraction from Rat striatum has been investigated in the presence of 20 mum bacitracin which prevents its hydrolysis. After deduction of a low-affinity, "non-saturable" component, the saturation kinetics at equilibrium provide evidence for two distinct saturable sites. The first exhibits Michaelis kinetics with a Kd value of 2.7 +/- 0.1 nM; both morphine and naloxone compete with the binding of 3H-Leu-Enkephalin on this site but not on the second one. The marked decrease in binding of 3H-Leu-Enkephalin observed in the presence of high concentration of sodium ions indicates that these two pentapeptides have the same properties as morphinomimetic analgesics. Taken together, these data indicate that the first site is identical to the "opiate receptor", while the nature of the second saturable site remains to be established.

Follicular variation in ovarian 11 beta-hydroxysteroid dehydrogenase (11 beta HSD) activities: evidence for the paracrine inhibition of 11 beta HSD in human granulosa-lutein cells.

The tablet is based on interactive mixtures of components, consisting of carrier particles partially covered by fine dry particles of the drug, in this case fentanyl citrate. In the interests of increasing retention of the drug at the site of absorption in the oral cavity, a bioadhesive component was also added to the carrier particles. Tablets containing 100, 200 and 400 microg of fentanyl were tested both in vitro and in vivo. The tablets disintegrated rapidly and dissolution tests revealed that fentanyl citrate was dissolved from the formulation almost instantly. Plasma concentrations of fentanyl were obtained within 10 min, with no second peak.

In vitro and in vivo evaluation of a new sublingual tablet system for rapid oromucosal absorption using fentanyl citrate as the active substance. Oromucosal delivery of drugs promotes rapid absorption and high bioavailability, with subsequent almost immediate onset of pharmacological effect. However, many oromucosal delivery systems are compromised by the possibility of the patient swallowing the active substance before it has been released and absorbed locally into the systemic circulation. This paper introduces a new tablet system for sublingual administration and rapid drug absorption. The tablet is based on interactive mixtures of components, consisting of carrier particles partially covered by fine dry particles of the drug, in this case fentanyl citrate. In the interests of increasing retention of the drug at the site of absorption in the oral cavity, a bioadhesive component was also added to the carrier particles. Tablets containing 100, 200 and 400 microg of fentanyl were tested both in vitro and in vivo. The tablets disintegrated rapidly and dissolution tests revealed that fentanyl citrate was dissolved from the formulation almost instantly. Plasma concentrations of fentanyl were obtained within 10 min, with no second peak. These results indicated that the bioadhesive component prevented the fentanyl from being swallowed (the fraction swallowed was considered smaller compared to other mucosal delivery systems), without hindering its release and absorption. This new sublingual tablet formulation may also hold potential for other substances where a rapid onset of effect is desirable.

We also examined the anti-cancer agent, di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT), which induces NDRG1 expression and causes ER stress. The expression of NDRG1 was demonstrated to regulate the three main arms of the ER stress response by: (1) increasing the expression of three major ER chaperones, binding immunoglobulin protein (BiP), calreticulin, and calnexin; (2) suppressing the protein kinase, RNA-activated (PKR)-like ER kinase (PERK); (3) inhibiting the inositol-requiring kinase 1alpha (IRE1alpha) arm; and (4) increasing the cleavage of activating transcription factor 6 (ATF6). An important finding was that NDRG1 enhances the anti-proliferative and anti-migratory activity of Dp44mT. This increased efficacy could be related to the following effects in the presence of Dp44mT and NDRG1, namely: markedly increased activation of the PERK target, eukaryotic translation initiation factor 2alpha (eIF2alpha); the maintenance of activating transcription factor 4 (ATF4) expression; high cytosolic Ca+2 that increases the sensitivity of cells to apoptosis via activation of the calmodulin-dependent kinase II (CaMKII) signaling cascade; and increased pro-apoptotic C/EBP-homologous protein (CHOP) expression.

The metastasis suppressor, NDRG1, differentially modulates the endoplasmic reticulum stress response. The metastasis suppressor, N-myc downstream regulated gene-1 (NDRG1), is a stress response protein that is involved in the inhibition of multiple oncogenic signaling pathways. Initial studies have linked NDRG1 and the endoplasmic reticulum (ER) stress response. Considering this, we extensively examined the mechanism by which NDRG1 regulates the ER stress response in pancreatic and colon cancer cells. We also examined the anti-cancer agent, di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT), which induces NDRG1 expression and causes ER stress. The expression of NDRG1 was demonstrated to regulate the three main arms of the ER stress response by: (1) increasing the expression of three major ER chaperones, binding immunoglobulin protein (BiP), calreticulin, and calnexin; (2) suppressing the protein kinase, RNA-activated (PKR)-like ER kinase (PERK); (3) inhibiting the inositol-requiring kinase 1alpha (IRE1alpha) arm; and (4) increasing the cleavage of activating transcription factor 6 (ATF6). An important finding was that NDRG1 enhances the anti-proliferative and anti-migratory activity of Dp44mT. This increased efficacy could be related to the following effects in the presence of Dp44mT and NDRG1, namely: markedly increased activation of the PERK target, eukaryotic translation initiation factor 2alpha (eIF2alpha); the maintenance of activating transcription factor 4 (ATF4) expression; high cytosolic Ca+2 that increases the sensitivity of cells to apoptosis via activation of the calmodulin-dependent kinase II (CaMKII) signaling cascade; and increased pro-apoptotic C/EBP-homologous protein (CHOP) expression. Collectively, this investigation dissects the molecular mechanisms through which NDRG1 manipulates the ER stress response and its ability to potentiate the activity of the potent anti-cancer agent, Dp44mT.

The advantages of humeral anteromedial plate osteosynthesis in the middle third shaft fractures. BACKGROUND: Humeral shaft fractures account for 1.2% of all fractures and occur in a slightly younger population. Their causes include a fall from standing or from height, motor vehicle accident, but can be also pathological. In order to clarify which of both surgeries we performed in our Department for treating humeral shaft fractures had more advantages (anterolateral or anteromedial plating through anterolateral approach) we analyzed incidence of postoperative iatrogenic radial palsies and mean operation time required to complete each surgery.

In HAECs, pharmacological inhibition of NHE function also caused defective ciliation and regeneration in airway MCCs. Collectively, our data revealed a requirement for NHEs in vertebrate mucociliary epithelia and linked NHE activity to cilia formation and function in differentiating MCCs.

Clearance defects were caused by reduced cilia formation, disrupted alignment of basal bodies in multiciliated cells (MCCs), and dysregulated mucociliary gene expression. These data also suggested that NHEs may contribute to the activation of Wnt signaling in mucociliary epithelia. In HAECs, pharmacological inhibition of NHE function also caused defective ciliation and regeneration in airway MCCs. Collectively, our data revealed a requirement for NHEs in vertebrate mucociliary epithelia and linked NHE activity to cilia formation and function in differentiating MCCs. Our results provide an entry point for the understanding of the contribution of NHEs to signaling, development, and pathogenesis in the human respiratory tract.

Biased utilization of DHQ52 and JH4 gene segments in a human Ig transgenic minilocus is independent of antigenic selection. We have assessed the effect of antigenic selection on human Ig heavy chain D and JH gene segment utilization in mice that contain transgenes composed of 2 VH (psi VH3-105 and VH5-251), 10 D, 6 JH, C mu, and C gamma 1 human gene segments. Human heavy chains using the functional VH5-251 gene segment are expressed in the serum and on the surface of murine B cells. The second VH gene segment (psi VH3-105) is not expressed as a protein but is rearranged and transcribed into mRNA. We previously reported that the functional VH5-251 mu transcripts preferentially used the DHQ52 and JH4 gene segments similar to their use in the human repertoire. Here, we demonstrate that the nonfunctional (psi VH3-105) gene segment shows the same bias in D and JH gene segment utilization. Because transcripts using the pseudo-VH gene segment cannot be subjected to antigenic selection, we conclude that the restricted repertoire observed is Ag independent. Analysis of pseudo VH gene segment recombination products reveals no bias in D gene segment reading frame utilization. Finally, we demonstrate that in the human transgene coding sequence complementarities can affect the recombination site and that D inversion is common.

Immunohistological staining of the sites of erythritol within infected mice indicated a higher than expected proportion of extracellular bacteria. Ensuing experiments suggested intracellular B. melitensis was unable to replicate within macrophages in the presence of erythritol and that erythritol was able to reach the site of intracellular bacteria. The intracellular inhibition of growth was found to encourage the bacteria to replicate extracellularly rather than intracellularly, a particularly interesting development in Brucella pathogenesis.

Erythritol triggers expression of virulence traits in Brucella melitensis. Erythritol is a four-carbon sugar preferentially utilized by Brucella spp. The presence of erythritol in the placentas of goats, cows, and pigs has been used to explain the localization of Brucella to these sites and the subsequent accumulation of large amounts of bacteria, eventually leading to abortion. Here we show that Brucella melitensis will also localize to an artificial site of erythritol within a mouse, providing a potential model system to study the pathogenesis of Brucella abortion. Immunohistological staining of the sites of erythritol within infected mice indicated a higher than expected proportion of extracellular bacteria. Ensuing experiments suggested intracellular B. melitensis was unable to replicate within macrophages in the presence of erythritol and that erythritol was able to reach the site of intracellular bacteria. The intracellular inhibition of growth was found to encourage the bacteria to replicate extracellularly rather than intracellularly, a particularly interesting development in Brucella pathogenesis. To determine the effect of erythritol on expression of B. melitensis genes, bacteria grown either with or without erythritol were analyzed by microarray. Two major virulence pathways were up-regulated in response to exposure to erythritol (the type IV secretion system VirB and flagellar proteins), suggesting a role for erythritol in virulence.

Hundreds of genetic, metabolic and environmental factors are known to increase the risk of ASD. Similar factors are known to influence the risk of schizophrenia and bipolar disorder; however, a unifying mechanistic explanation has remained elusive. Here we used the maternal immune activation (MIA) mouse model of neurodevelopmental and neuropsychiatric disorders to study the effects of a single dose of the antipurinergic drug suramin on the behavior and metabolism of adult animals. We found that disturbances in social behavior, novelty preference and metabolism are not permanent but are treatable with antipurinergic therapy (APT) in this model of ASD and schizophrenia. A single dose of suramin (20 mg kg(-1) intraperitoneally (i.p.)) given to 6-month-old adults restored normal social behavior, novelty preference and metabolism. Comprehensive metabolomic analysis identified purine metabolism as the key regulatory pathway. Correction of purine metabolism normalized 17 of 18 metabolic pathways that were disturbed in the MIA model. Two days after treatment, the suramin concentration in the plasma and brainstem was 7.64 muM pmol mul(-1) (+-0.50) and 5.15 pmol mg(-1) (+-0.49), respectively. These data show good uptake of suramin into the central nervous system at the level of the brainstem. Most of the improvements associated with APT were lost after 5 weeks of drug washout, consistent with the 1-week plasma half-life of suramin in mice.

Furthermore, because hypermutated MMRd prostate cancers can respond to immune checkpoint inhibitors, there is an urgent need for practical detection tools. EXPERIMENTAL DESIGN: We analyzed plasma cell-free DNA-targeted sequencing data from 433 patients with mPC with circulating tumor DNA (ctDNA) purity >=2%. Samples with somatic hypermutation were subjected to 185 x whole-exome sequencing and capture of mismatch repair gene introns. Archival tissue was analyzed with targeted sequencing and IHC. RESULTS: Sixteen patients (3.7%) had somatic hypermutation with MMRd etiology, evidenced by deleterious alterations in MSH2, MSH6, or MLH1, microsatellite instability, and characteristic trinucleotide signatures. ctDNA was concordant with mismatch repair protein IHC and DNA sequencing of tumor tissue. Tumor suppressors such as PTEN, RB1, and TP53 were inactivated by mutation rather than copy-number loss. Hotspot mutations in oncogenes such as AKT1, PIK3CA, and CTNNB1 were common, and the androgen receptor (AR)-ligand binding domain was mutated in 9 of 16 patients. We observed high intrapatient clonal diversity, evidenced by subclonal driver mutations and shifts in mutation allele frequency over time. Patients with hypermutation and MMRd etiology in ctDNA had a poor response to AR inhibition and inferior survival compared with a control cohort. CONCLUSIONS: Hypermutated MMRd mPC is associated with oncogene activation and subclonal diversity, which may contribute to a clinically aggressive disposition in selected patients.

Measurements of ionic fluoride in milk. Procedures used for measuring ionic fluoride in both human and cow's milk have been investigated. A number of factors were found to affect fluoride ion measurements in milk samples including time, stirring and the method of cleaning the fluoride electrode. Following these investigations a procedure was developed for estimating ionic fluoride in milk. Human milk collected from a fluoridated area (Newcastle-upon-Tyne) was found to contain significantly more ionic fluoride (0.065 ppm) than human milk from mothers in a non-fluoridated area (Dundee, 0.035 ppm).

The entire process of thrombin generation as measured by global hemostasis tests like activated partial thromboplastin time clot waveform analysis (APTT CWA) and thrombin generation test (TGT) may reflect the actual bleeding phenotype. Aims: To assess the utility of TGT and CWA as a screening tool to identify bleeders and to evaluate the bleeding phenotype in Hemophilia A. Settings and Design: Prospective, observational study of 147 consecutive patients referred for coagulation workup. Subjects and Methods: Bleeding assessment tool was used to identify bleeders. Patients were classified as severe and nonsevere bleeders based on clinical criteria. TGT was performed by calibrated automated thrombogram, CWA by photo-optical coagulometer and factor levels by one stage clot-based assays. Statistical Analysis Used: The Kruskal-Wallis test with post-hoc analysis was done to examine the difference in CWA/TGT parameters amongst hemophilia classified by FVIII levels. Receiver operating characteristic (ROC) analysis was performed to estimate the diagnostic accuracy of CWA and TGT in discriminating between clinically severe vs nonsevere bleeders. Results: Using ROC derived cut-offs of min1, min2 and peak height of thrombin (PH), the sensitivity (min1:91.67%, min2:91.67%, PH: 97.22%, FVIII: 86.11%) and specificity (min1:100%, min2:100%, PH: 90.91%, FVIII: 90.91%) of CWA/TGT was superior to FVIII to distinguish between clinically severe vs nonsevere bleeders.

Clinical utility of activated partial thromboplastin time clot waveform analysis and thrombin generation test in the evaluation of bleeding phenotype in Hemophilia A. Context: Hemophilia A is classified as mild, moderate, and severe based on Factor VIII levels (FVIII). Clot-based assays only detect initiation of thrombin generation, hence FVIII levels may not accurately predict the bleeding risk in all hemophilia patients. The entire process of thrombin generation as measured by global hemostasis tests like activated partial thromboplastin time clot waveform analysis (APTT CWA) and thrombin generation test (TGT) may reflect the actual bleeding phenotype. Aims: To assess the utility of TGT and CWA as a screening tool to identify bleeders and to evaluate the bleeding phenotype in Hemophilia A. Settings and Design: Prospective, observational study of 147 consecutive patients referred for coagulation workup. Subjects and Methods: Bleeding assessment tool was used to identify bleeders. Patients were classified as severe and nonsevere bleeders based on clinical criteria. TGT was performed by calibrated automated thrombogram, CWA by photo-optical coagulometer and factor levels by one stage clot-based assays. Statistical Analysis Used: The Kruskal-Wallis test with post-hoc analysis was done to examine the difference in CWA/TGT parameters amongst hemophilia classified by FVIII levels. Receiver operating characteristic (ROC) analysis was performed to estimate the diagnostic accuracy of CWA and TGT in discriminating between clinically severe vs nonsevere bleeders. Results: Using ROC derived cut-offs of min1, min2 and peak height of thrombin (PH), the sensitivity (min1:91.67%, min2:91.67%, PH: 97.22%, FVIII: 86.11%) and specificity (min1:100%, min2:100%, PH: 90.91%, FVIII: 90.91%) of CWA/TGT was superior to FVIII to distinguish between clinically severe vs nonsevere bleeders. Phenotypic heterogeneity of bleeding severity was identified in our study population. Clinical severity correlated with CWA/TGT parameters instead of FVIII levels. Conclusions: CWA and TGT are more effective tools than conventional factor assays to identify clinically severe bleeders and tailor prophylaxis as per bleeding phenotype.

The pursuit of thinness: a study of Dublin schoolgirls aged 15 y. Despite increasing trends in the prevalence of overweight and obesity, fatness phobia is common during female adolescence. This study has demonstrated a high level of dissatisfaction with body weight in a sample of Dublin schoolgirls aged 15 y. Of 420 subjects, 59% reported that they wanted to be slimmer and 68% had previously tried to lose weight. Contrary to expectations, overweight girls were not found to hold the monopoly on such dissatisfactions. Normal weight and even underweight girls also expressed a desire to be thinner and reported using unhealthy weight control practices including random avoidance of staple foods, fasting, smoking and purging, in their pursuit of the 'perfect' female figure. Obesity prevention programmes which target adolescent girls 'at risk' of overweight and obesity, must take cognizance of their profound fear of fatness, otherwise the use of harmful slimming strategies may be further increased as teenage girls frantically try to lose weight and to avoid the stigma associated with female fatness.

Glucuronidated drug metabolites can be quantified from urine samples by first hydrolyzing conjugates with beta-glucuronidase (beta-GUS) and then separating free drug molecules by liquid chromatography and mass spectrometry detection (LC-MS). To improve the activity and specificity of various beta-GUS, we designed enzyme chimeras and generated site-saturation variants based on structural analyses, then screened them for improved activity on drug metabolites important to clinical and forensic drug-testing laboratories. Often, an increase of activity on one substrate of interest was countered by loss of activity against another, and there was no strong correlation of activity on standard beta-glucuronidase substrates to activity on recalcitrant drug glucuronides. However, we discovered a chimera of two enzymes from different species of Aspergillus that displays a 27 % increase in activity on morphine-3-glucuronide than the parent proteins. Furthermore, mutations in the M-loop, which is a loop near the active site, resulted in numerous variants with dramatically increased rates of hydrolysis on drug glucuronides. Specifically, the M-loop variant Q451D/A452E of a beta-GUS from Brachyspira pilosicoli has a 50-fold and 25-fold increase in activity on the recalcitrant substrates codeine-6-glucuronide and dihydrocodeine-6-glucuronide, respectively, compared to the parent enzyme.

Alcohol withdrawal syndrome requires pharmacological treatment for the treatment of withdrawal symptoms and to prevent withdrawal complications. Medically assisted withdrawal treatment is used in alcohol treatment units, but it is also frequently required in patients admitted to hospital for other conditions. METHODS: Review of major guidelines covering treatment of withdrawal syndrome with the aim to describe recent evidence and recommendations about the pharmacological treatment for alcohol withdrawal syndrome. RESULTS: Four major guidelines concerning treatment of withdrawal syndrome were selected (National Institute for Health and Care Excellence, American Society of Addiction Medicine, World Federation of Societies of Biological Psychiatry and American Psychiatric Association) and screened for the recommendations and level of evidence on drug prescribing for alcohol withdrawal syndrome. The Maudsley guidelines were also considered in this review. DISCUSSION: All the four reviewed guidelines recommended benzodiazepines as the first line treatment for alcohol withdrawal syndrome. The association of anticonvulsivants, adrenergic alpha-2 agonists, betablockers and antipsychotics with benzodiazepines is recommended for symptom reduction in severe alcohol withdrawal syndrome.

[Pharmacological Treatment of Alcohol Withdrawal]. INTRODUCTION: Excessive chronic alcohol users, and particularly patients with alcohol use disorder, may present an alcohol withdrawal syndrome if they abruptly stop drinking. Alcohol withdrawal syndrome requires pharmacological treatment for the treatment of withdrawal symptoms and to prevent withdrawal complications. Medically assisted withdrawal treatment is used in alcohol treatment units, but it is also frequently required in patients admitted to hospital for other conditions. METHODS: Review of major guidelines covering treatment of withdrawal syndrome with the aim to describe recent evidence and recommendations about the pharmacological treatment for alcohol withdrawal syndrome. RESULTS: Four major guidelines concerning treatment of withdrawal syndrome were selected (National Institute for Health and Care Excellence, American Society of Addiction Medicine, World Federation of Societies of Biological Psychiatry and American Psychiatric Association) and screened for the recommendations and level of evidence on drug prescribing for alcohol withdrawal syndrome. The Maudsley guidelines were also considered in this review. DISCUSSION: All the four reviewed guidelines recommended benzodiazepines as the first line treatment for alcohol withdrawal syndrome. The association of anticonvulsivants, adrenergic alpha-2 agonists, betablockers and antipsychotics with benzodiazepines is recommended for symptom reduction in severe alcohol withdrawal syndrome. Thiamine should be administered to all patients to prevent Wernicke-Korsakoff encephalopathy. If there is any electrolytic imbalance it should be corrected. CONCLUSION: Maintaining a high level of suspicion for alcohol withdrawal syndrome is important across all clinical settings, and it should be promptly treated.

Two cases of asbestosis and one case of rounded atelectasis due to non-occupational asbestos exposure. Asbestos is a well-known cause of several neoplastic (malignant mesothelioma, lung cancer) and non-neoplastic (asbestosis, pleuropathies) occupational diseases. Lower-level exposure in the general environment may induce pleural plaques and thickenings, and is associated with an increased mesothelioma risk. We present two patients (a 68-year-old man and a 72-year-old woman) who developed asbestosis (in association with pleural plaques and calcifications), and a 78-year-old man who developed rounded atelectasis (with pleural plaques and benign effusion), after living for several decades in the proximity of large Italian asbestos-cement plant. None of them had been exposed to asbestos occupationally. Besides living in a contaminated area, the woman used to clean the work clothes of her brother, who was employed in the local asbestos factory.

Pulse wave velocity and ankle brachial index in patients with Kawasaki disease. BACKGROUND: Pulse wave velocity (PWV) and ankle brachial index (ABI) are a useful method to estimate atherosclerosis in adults, while a history of Kawasaki disease (KD) may be a risk factor for later atherosclerosis of systemic arteries. PWV and ABI in patients with a history of KD have not been reported. METHOD: In total, 90 patients ranging in age from 4 to 25 years who had a history of KD previously, any time from 1 month to 19 years ago, were studied. As a control group, 119 patients with other trivial cardiovascular diseases such as a small ventricular, an atrial septal defect or mild arrhythmias, were also evaluated. A high value of PWV was determined as >/=120% of normal predicted value of PWV, while a low value of ABI was determined as </=0.9. Age, sex, height, weight, body mass index, blood pressure, ABI and PWV by t-test, and univariate and multivariate analyses of a logistic-regression model, were analyzed. RESULTS: When a cut-off point was set as per cent of normal predicted PWV (%N PWV) >/= 120%, and ABI </= 0.9, patients with a history of KD had a higher PWV than the control group, while there was no significant difference in the ABI between the two groups. There was no significant difference in the PWV or the ABI between the KD patients with or without coronary aneurysms. CONCLUSION: Patients with a history of KD may have increased aortic stiffness for their age.

The results of cataract nigra cases operated with the mini-nuc technique. The purpose of this study was to evaluate the efficacy and safety of the mini-nuc technique for the removal of brunescent and black cataracts. A prospective study was carried out in 33 eyes of 33 patients with cataract nigra operated with the mini-nuc technique between April 2002 and June 2003. Slit-lamp examinations, intraocular pressure (IOP) measurements, and best-corrected visual acuity (BCVA) were assessed pre- and postoperatively. Accompanying systemic diseases were noted. Intraoperative and postoperative complications were evaluated. Unilateral eyes of 33 patients (18 male [54.5%], 15 female [45.5%]) aged between 65 and 90 years (mean 72 years) were operated with the mini-nuc technique. Preoperative BCVA values varied between light perception and 0.2 in the Snellen chart. Intraocular lenses (IOL) were implanted into all of the patients (27 in-the-bag [81.8%], four to sulcus [12.1%], and two with scleral fixation [6.1%]). During the surgery, five patients (15.15%) had zonular dialysis and two (6.1%) had posterior capsule rupture and vitreous loss. Postoperatively, three (9.1%) rises in IOP, two (6.1%) hyphema, and one (3%) IOL subluxation were observed. At the first day visit, the mean of the uncorrected visual acuities (UCVA) was 0.5 in the Snellen chart. At the third month visit, the mean BCVA was observed to be 0.8. The residual mean astigmatism was 0.75 D against the rule. The mini-nuc technique was effective in removing brunescent and black cataracts with a low rate of serious complications. The mini-nuc technique, which is also performed with a small incision and without sutures, might be an alternative to phacoemulsification in cases of cataract nigra.

To this end, spliceome-profiling is a new methodological approach that has considerable conceptual relevance for discovery and clinical translation of novel biomarkers for psychiatric illnesses. Advances in microarray technology now allow for improved sensitivity in measuring the transcriptome while simultaneously querying the \"exome\" (all exons) and \"spliceome\" (all alternatively spliced variants). The present study aimed to evaluate the feasibility of spliceome-profiling to discern transcriptomic biomarkers of psychosis. METHODS: We measured exome and spliceome expression in peripheral blood mononuclear cells from 13 schizophrenia patients, nine bipolar disorder patients, and eight healthy control subjects. Each diagnostic group was compared to each other, and the combined group of bipolar disorder and schizophrenia patients was also compared to the control group. Furthermore, we compared subjects with a history of psychosis to subjects without such history. RESULTS: After applying Bonferroni corrections for the 21,866 full-length gene transcripts analyzed, we found significant interactions between diagnostic group and exon identity, consistent with group differences in rates or types of alternative splicing. Relative to the control group, 18 genes in the bipolar disorder group, eight genes in the schizophrenia group, and 15 genes in the combined bipolar disorder and schizophrenia group appeared differentially spliced. Importantly, thirty-three genes showed differential splicing patterns between the bipolar disorder and schizophrenia groups. More frequent exon inclusion and/or over-expression was observed in psychosis. Finally, these observations are reconciled with an analysis of the ontologies, the pathways and the protein domains significantly over-represented among the alternatively spliced genes, several of which support prior discoveries. CONCLUSIONS: To our knowledge, this is the first blood-based spliceome-profiling study of schizophrenia and bipolar disorder to be reported. The battery of alternatively spliced genes and exons identified in this discovery-oriented exploratory study, if replicated, may have potential utility to discern the molecular subtypes of psychosis. Spliceome-profiling, as a new methodological approach in transcriptomics, warrants further work to evaluate its utility in personalized medicine. Potentially, this approach could also permit the future development of tissue-sampling methodologies in a form that is more acceptable to patients and thereby allow monitoring of dynamic and time-dependent plasticity in disease severity and response to therapeutic interventions in clinical psychiatry." ], "offsets": [ [ 146, 3129 ] ] } ]

Altogether, these antivirals have offered novel options for the treatment of patients who did not respond to previous therapy with interferon alpha, the only available treatment against CHB until 1998. However, therapies using analogues of nucleos(t)ides have been confronted with viral resistances which are often associated to with worsening of liver disease. Drug resistance is conferred by the appearance of one or several mutations within the HBV polymerase gene. These mutations confer to the mutant viral population a phenotypic advantage over the wild-type pretherapeutic viral quasispecies, as they induce a reduction of drug susceptibility of mutant strains in vivo. This reduction of drug susceptibility can be as well measured in vitro, i.e in cell culture, using phenotypic assays. The detection of these mutations has become of crucial importance to better adapt clinical option to the virological status of the patient. Genotypic and more recently phenotypic assays have been developed and both assays can be used for drug resistance testing. Genotypic assay gives information about already characterized mutations associated with viral resistance, while phenotypic testing measures the overall drug susceptibility of patient-derived viral strains in cell culture. These assays are described and their potential use in the clinical setting is discussed." ], "offsets": [ [ 113, 1743 ] ] } ]

Altogether, these antivirals have offered novel options for the treatment of patients who did not respond to previous therapy with interferon alpha, the only available treatment against CHB until 1998. However, therapies using analogues of nucleos(t)ides have been confronted with viral resistances which are often associated to with worsening of liver disease. Drug resistance is conferred by the appearance of one or several mutations within the HBV polymerase gene. These mutations confer to the mutant viral population a phenotypic advantage over the wild-type pretherapeutic viral quasispecies, as they induce a reduction of drug susceptibility of mutant strains in vivo. This reduction of drug susceptibility can be as well measured in vitro, i.e in cell culture, using phenotypic assays. The detection of these mutations has become of crucial importance to better adapt clinical option to the virological status of the patient. Genotypic and more recently phenotypic assays have been developed and both assays can be used for drug resistance testing. Genotypic assay gives information about already characterized mutations associated with viral resistance, while phenotypic testing measures the overall drug susceptibility of patient-derived viral strains in cell culture. These assays are described and their potential use in the clinical setting is discussed.
