Abstract
Current vaccine approaches to combat anthrax are effective; however, they target only a single protein [the protective antigen (PA) toxin component] that is produced after spore germination. PA production is subsequently increased during later vegetative cell proliferation. Accordingly, several aspects of the vaccine strategy could be improved. The inclusion of spore-specific antigens with PA could potentially induce protection to initial stages of the disease. Moreover, adding other epitopes to the current vaccine strategy will decrease the likelihood of encountering a strain of Bacillus anthracis (emerging or engineered) that is refractory to the vaccine. Adding recombinant spore-surface antigens (e.g. BclA, ExsFA/BxpB and p5303) to PA has been shown to augment protection afforded by the latter using a challenge model employing immunosuppressed mice challenged with spores derived from the attenuated Sterne strain of B. anthracis. This report demonstrated similar augmentation utilizing guinea pigs or mice challenged with spores of the fully virulent Ames strain or a non-toxigenic but encapsulated ΔAmes strain of B. anthracis, respectively. Additionally, it was shown that immune interference did not occur if optimal amounts of antigen were administered. By administering the toxin and spore-based immunogens simultaneously, a significant adjuvant effect was also observed in some cases. Thus, these data further support the inclusion of recombinant spore antigens in next-generation anthrax vaccine strategies.

Abstract
PURPOSE Several dietary factors have been associated with glaucoma. Among them, dietary antioxidant intake (i.e., vitamin C and vitamin A) in association with glaucoma has been analyzed, but with mixed results. Genetic factors may play a role in modulating the effect of dietary antioxidant intake on glaucoma; however, nutrigenetic studies in this field are scarce. Our aim was to study the association between selected polymorphisms in key proteins related to vitamin C and vitamin A concentrations and primary open-angle glaucoma (POAG). METHODS We performed a case-control study matched for age, sex, and bodyweight. We recruited 300 subjects (150 POAG cases and 150 controls) from a Mediterranean population and determined the plasma concentrations of vitamin C and vitamin A for each subject. We selected the following single-nucleotide polymorphisms (SNPs) in genes related to vitamin A and vitamin C concentrations: rs176990 and rs190910 in the retinol-binding protein 1 (RBP1) gene; and rs10063949 and rs1279683 in the Na⁺-dependent L-ascorbic acid transporters 1 and 2, respectively (encoded by the SLC23A1 and SLC23A2 genes). RESULTS We found a statistically significant association between the rs1279386 (A>G) SNP in SLC23A2 and POAG risk. In the crude analysis, homozygous subjects for the G allele (GG subjects) had higher risk of POAG than other genotypes (OR: 1.67; 95% CI: 1.03-2.71). This association remained statistically significant (p=0.010) after multivariate adjustment for potential confounders. We also found that POAG patients had lower plasma vitamin C concentrations than control subjects (9.9±1.7 µg/ml versus 11.7±1.8 µg/ml, p<0.001). Moreover, we consistently detected a significant association between the rs1279386 SNP in SLC23A2 and plasma vitamin C concentrations: GG subjects had significantly lower plasma vitamin C concentrations than the other genotypes (9.0±1.4 µg/ml versus 10.5±1.6 µg/ml, p<0.001 in POAG cases and 10.9±1.6 µg/ml versus 12.1±1.8 µg/ml, p<0.001 in controls). The rs10063949 SNP in SLC23A1 was not associated with either plasma vitamin C concentrations or POAG risk. Similarly, SNPs in RBP1 were not associated with vitamin A concentrations or POAG risk. CONCLUSIONS The rs1279683 SNP in SLC23A2 was significantly associated with lower plasma concentrations of vitamin C and with higher risk of POAG in GG subjects.

Abstract
Presence, sources and behaviour of polybrominated diphenyl ethers (PBDEs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were evaluated in Spanish sewage sludge. A total of 120 samples were seasonally collected from October 2005 to September 2006 at 31 urban wastewater treatment plants (WWTPs). Concentrations of PBDEs (ranging between 57.5 and 2606 ng/g dry weight) were two to three orders of magnitude higher than those obtained for PCDDs (0.17-5.03 ng/g d.w.) and PCDFs (0.05-3.07 ng/g d.w.). All the samples presented International Toxicity Equivalents (I-TEQ) levels (ranging between 2.06 and 44.4 ng/kg d.w.) below the limit values proposed by European Union for land application. Congener patterns evaluation revealed that the use of Deca-BDE commercial mixture seems to be the major source of PBDEs in the sludge. Nevertheless, origin of PCDD/Fs should be related to atmospheric deposition, faeces and presence of PCDD/Fs precursors such as pentachlorophenol in the sludge. No correlations (p>0.05) were found between pollutant concentrations (PBDEs and PCDD/Fs) and wastewater treatment plant (WWTP) characteristics (capacity nor sludge rate). Lower levels of PBDEs and PCDFs were found in WWTPs using biological nitrogen and phosphorous elimination, suggesting that these compounds are susceptible of microbial elimination. According to our knowledge, this is the first work comparing together both PBDEs and PCDD/Fs sludge patterns.

Abstract
BACKGROUND Orthotopic liver transplantation (OLT) for patients with cirrhosis and concomitant hepatocellular carcinoma (HCC) in early stages is the treatment of choice, with an acceptable recurrence rate and excellent survival. AIM We sought to evaluate (1) the accuracy of preoperative imaging; (2) the impact of pre-OLT treatments on survival and recurrence; and (3) the influence of beyond Milan criteria selection on global outcomes. METHODS We studied a cohort of 65 patients with HCC among 300 consecutive OLTs over a single 12-year experience. We analyzed the overall outcomes of survival and recurrence, the accuracy of preoperative diagnosis and staging the influence of neoadjuvant treatment prior to OLT, and the effect on overall outcomes beyond the Milan criteria in our series. RESULTS The 65 transplants were performed for HCC, mostly in association with hepatitis C virus and alcoholic cirrhosis with HTP. At a mean follow-up of 40.32 months, the recurrence rate was 5.7% among the 61 HCC confirmed by histopathology. The overall survival was 30.07. Actuarial survivals at 1, 5, and 10 years were 82%, 77%, and 62%, respectively. Six retransplants occurred among the seven graft losses albeit with poor survival after the second graft. Most explants showed low pTNM stages with favorable microscopic features. Preoperative imaging tests failed to achieve an accurate diagnosis in 15.38% of the series. The role of alpha-fetoprotein (AFP) and hepatic biopsy was irrelevant. Unfavorable histopathologic factors predicted a greater recurrence rate, but had no influence on survival. Neither recurrence nor survival were modified by pre-OLT therapy. CONCLUSIONS In our series, AFP, hepatic biopsy, and pre-OLT treatment had limited roles. Radiological imaging techniques underestimated HCC staging and lead to a misdiagnosis to an expected degree. Despite these findings, this single institution experience with OLT for HCC showed excellent survivals with a low recurrence rate including cases of patients beyond the Milan criteria.

Abstract
We report a case of fatal sodium poisoning due to the unintentional use of 20% hypertonic saline serum during peritoneal lavage after intestinal resection. The patient presented with unconsciousness, metabolic acidosis, and plasma sodium concentration of 193 mE/l. After 3 hours, he developed paroxysmal supraventricular tachycardia, hyperthermia, generalized tonic-clonic convulsions, disseminated intravascular coagulation, and adult respiratory distress syndrome. The patient died 15 hours after the operation. Pathological examination revealed cerebral and lung oedema, pericentral hepatic necrosis, and fibrin thrombi in the lungs, stomach, and kidneys. We review, in addition, other reported cases of sodium poisoning.

Abstract
The mechanical behavior of the young bull pericardium in a fatigue test has been studied. This material is a similar tissue to those used in valve leaflet construction for a cardiac bioprosthesis. The consumed energy on each test was evaluated and afterwards used as a predictor of the biomaterial strength. Two-hundred and nine samples were tested to cyclical fatigue. The cut-off point to determine the sample quality was whether or not they resisted at least 4500 cycles. Only 22 samples withstood over that point (10.52%). The samples were classified according to their fatigue behavior in excellent, undefined and unsuitable. By using as a reference the consumed energy in the first 25 cycles, we could distinguish correctly (between 93.2 and 96.1%) the unsuitable material and most of the excellent (between 78.1 and 95.2%). From the rejected material 77% was really detachable and from the accepted, only 50% was excellent, with an equal methodology. The receiver operating characteristics curve was employed to establish decision levels when selecting samples, being 0.85 the best area (theoretical maximum value of 1). It is concluded that the energy wasted is a good predictor of the strength of the tissue. More than 90% of the unsuitable material and 50% of the excellent material (5% of all the material) is detected with this method.

Abstract
Glucokinase hyperinsulinism is a rare variant of congenital hyperinsulinism caused by activating mutations in the glucokinase gene and has been reported so far to be a result of overactivity of glucokinase within the pancreatic beta-cell. Here we report on a new patient with difficulties to diagnose persistent hyperinsulinism and discuss diagnostic procedures of this as well as the other reported individuals. After neonatal hypoglycemia, the patient was reevaluated at the age of 3 years for developmental delay. Morning glucose after overnight fast was 2.5-3.6 mmol/l. Fasting tests revealed supressed insulin secretion at the end of fasting (1.4-14.5 pmol/l). In addition, diagnostic data of the patients reported so far were reviewed. A novel heterozygous missense mutation in exon 10 c.1354G>C (p.Val452Leu) was found and functional studies confirmed the activating mutation. There was no single consistent diagnostic criterion found for our patient and glucokinase hyperinsulinism individuals in general. Often at the time of hypoglycemia low insulin levels were found. Therefore insulin concentrations at hypoglycemia, or during fasting test as well as reactive hypoglycemia after an oral glucose tolerance test were not conclusive for all patients. A glucose lowering effect in extra-pancreatic tissues independent from hyperinsulinism that results in diagnostic difficulties may contribute to underestimation of glucokinase hyperinsulinism. Mutational analysis of the GCK-gene should be performed in all individuals with unclear episodes of hypoglycemia even without documented hyperinsulinism during hypoglycemia. Delay of diagnosis might result in mental handicap of the affected individuals.

Abstract
OBJECTIVE To assess the effect of pentoxiphylline (a potent inhibitor of tumor necrosis factor alpha) on survival, on systemic and portal hemodynamics, and on cardiac function in patients with alcoholic cirrhosis. DESIGN A randomized double-blind placebo-controlled trial. SETTING A single center using parallel groups of patients to compare pentoxiphylline with placebo. PATIENTS We recruited 24 patients with alcoholic cirrhosis (8 Child-Pugh B and 16 Child-Pugh C). INTERVENTIONS Patients were randomly assigned to receive pentoxiphylline (400 mg tid; n = 12) or placebo (n = 12) over a 4-week period. OUTCOME MEASURES The primary outcome was to extend short-term and long-term survival. Secondary outcomes included hemodynamic benefits (improvement in cardiac function and/or systemic vascular resistance index, or decrease in portal pressure). RESULTS Portal pressure and cardiac function remained unchanged and there were no significant differences in short-term or long-term survival between treatment and placebo groups. The group on pentoxiphylline increased systemic vascular resistance and decreased cardiac indices (from 1,721 +/- 567 to 2,082 +/- 622 dyn.sec(-1) cm(-5) m(-2) and from 4.17 +/- 1.4 to 3.4 +/- 0.9 l.m(-2), p = 0.05). CONCLUSIONS Although pentoxiphylline seems to provide some short-term hemodynamic benefits in patients with advanced alcoholic cirrhosis, this drug has no effect on survival or portal pressure in these patients.

Abstract
OBJECTIVES To analyze the clinical, etiologic and prognostic profile of anterior choroidal artery (AChA) infarcts. METHODS 42 consecutive patients with AChA infarction were included. Symptoms, etiology and scores on neurological and functional scales were analyzed on admission, discharge and at 3-month follow-up. A comparative study was performed between deep (n = 23) and deep + superficial (n = 19) infarcts. RESULTS Lacunar syndrome was present in 83.3% of patients. Etiology was large-vessel disease in 38.1% and cryptogenic in 38.1%. Ten patients had a National Institute of Health Stroke Scale score >7 on admission. At discharge, 45.3% had an modified Rankin Scale >2 (35.7% after 3 months). Infarcts involving superficial territory were more severe at admission (P = 0.034) and were associated with a worse functional status at discharge (P = 0.0008). CONCLUSION AChA infarcts usually present with lacunar syndrome, although they are often not lacunar infarcts. At discharge, almost half of the patients are dependent in their activities of daily living, and most remain so at 3-month follow-up. Infarcts involving superficial territory are associated with worse prognosis.

Abstract
A 53-year-old man who had worked for 17 years manufacturing car batteries, with overt exposure to lead, developed a clinical picture initially characterized by signs of parkinsonism, followed by atypical signs such as loss of memory, reduction of eye movement, dysarthria, chorea-like dyskinesia and sexual impotence. The diagnosis of atypical parkinsonism was eventually changed to progressive supranuclear palsy-like parkinsonism. The patient was treated with various anti-Parkinson's disease drugs, including levodopa, with modest improvement. The symptoms deteriorated progressively, leading to permanent occupational disability with noticeable limitation of daily activities. Toxicological studies revealed abnormally high blood levels of lead. Discontinuation of lead exposure was followed first by clinical stabilization and then steady improvement. This case confirms recent reports that link exposure to lead and its compounds with degenerative diseases of the central nervous system, such as Parkinson's disease.
