ABSTRACT
The physiological system of molluscs, particularly pro-oxidant and antioxidant mechanisms, could be altered by pollutants and induce disturbance on health status and productive parameters of aquatic organisms, such as oyster. Therefore, the aim of this study was to evaluate the chemical contamination in water (total metals and polycyclic aromatic hydrocarbons) and oxidative stress parameters in oysters (Crassostrea corteziensis) in Camichin estuary, located in Mexican Tropical Pacific. The results obtained showed the presence of arsenic, lead and zinc, as well as naphthalene, pyrene and benzo[a]pyrene in concentrations relatively higher than criteria established by local and international guidelines. Regarding the biomarkers of oxidative stress response (H2O2 and O2 concentration, catalase activity, lipid peroxidation, and hydroperoxide concentration), differences between oyster from estuary and control group were significant. These results indicate that these pollutants could be related with oxidative stress detected in oyster.

The most frequent form of spina bifida is myelomeningocele. There is no optimal postnatal treatment for this defect. In addition to the motor or sensory deficits, which depend on the location of the lesion, the defect is usually associated with Chiari ii malformation in affected children. Myelomeningocele has high mortality and, in up to 80% to 90% of patients, can be accompanied by hydrocephalus, which causes severe neurocognitive impairment and requires the patient to be shunted for survival. Intrauterine repair of fetal malformations employing open access through hysterotomy has become a therapeutic option due to improved anesthetic and surgical techniques and instrumentation, which have allowed this type of intervention to become relatively frequent. Anesthetic treatment should focus on both the mother and fetus and the hemodynamic factors regulating placental flow, uterine dynamics, blood loss and fetal well-being must remain well-controlled. Within our Program for Fetal Medicine and Therapy, 21 open fetal interventions have been performed: 17 EXIT procedures and 4 procedures for the intrauterine correction of fetal myelomeningocele. We describe our experience of the intrauterine repair of fetal myelomeningocele through open fetal surgery.

Suppression of soil-borne plant diseases with composts has been widely studied. Composts suppressive to soil-borne pathogens have been detected in various cropping systems. Vegetable plants are generally propagated in pots, allowing the use of suppressive substrates to control zoospore-producing pathogens, like Phytophthora sp. The objective of the present work was to assess compost suppressiveness against Phytophthora capsici on pepper (cv. Corno di Toro). A municipal compost showing a good suppressive activity in previous trials on vegetable crops was used. Compost was mixed at 10, 20, 40, 60, 80 and 100% (v/v) with a commercial peat substrate, used as control. Substrates have been inoculated at 0.25, 0.5 and 1 g/l with wheat and hemp kernels infested with P. capsici and after one week 10 plants were transplanted for each treatment in 4 trays of 10 liters volume capacity and placed in greenhouse at 20 degrees C. Diseased plants were assessed weekly after transplanting and above-ground biomass of plants was assessed at the end of the trials. Compost applied at 80% significantly controlled the disease at high inoculum density (1 g/l), while at lower inoculums density, 0.25 and 0.5 g/l, reduced compost applications, 40% and 60% respectively, were sufficient to significantly control the disease. The application of compost at 20%, in absence of the pathogen, increased the biomass of pepper plants compared to control. The use of compost based substrates can be a suitable strategy for controlling soil-borne diseases on pepper, but results depends on application rates.

OBJECTIVE: Accidental dura mater puncture is a potential complication during epidural block, and may be associated with multiple factors. Our objective was to determine the prevalence and risk factors of accidental dural puncture in a university hospital, evaluating the differences in the number of complications during different working hours. MATERIAL AND METHODS: A prospective observational study was conducted on all women who requested regional anaesthesia in the Epidural Analgesia Unit between 1 January 2009 and 1 January 2011, and who fulfilled the inclusion criteria. The technique employed to control labour pains was epidural analgesia. RESULTS: A total of 12,480 pregnant women were included. The prevalence of accidental dura mater puncture was 0.4% (50 patients). Of these, 28% were due to medical residents. More accidental dura mater punctures were observed during September and in the afternoon shift. CONCLUSIONS: The prevalence of accidental dura mater puncture is similar to other patient series. In ours, tiredness or lack of sleep did not influence the incidence of complications in analgesia for labour pains in a 24 hour care unit. This may be due to the distribution of on-call shifts not exceeding more than 6 hours.

A global assessment of arsenic (As), nickel (Ni), cobalt (Co) and chromium (Cr) was performed in environmental samples from an important industrial bay. Different fractions of water, sediments and tissues from four species of fish were analysed. Samples were collected from selected sampling sites during four consecutive samplings in spring and autumn seasons, in order to evaluate concentrations and their possible correlations among the aquatic compartments. While a higher availability of Cr and Ni was found in water, Co and As were the most available elements in sediments. In fish, the liver was the tissue with the highest proportion of As and Co, and gills showed the highest concentrations of Ni and Cr. Significance differences were observed among sites showing the pollution sources. In sediments, high correlations were found between total Co content and the most available fractions. Total Ni content highly correlated with the oxidisable fraction, while Cr total content tightly correlated with the least available fractions. Quality guideline values for sediments were frequently exceeded. In sediments and biota, concentrations were slightly higher than in other ecosystems, indicating that maritime, industrial and urban activities are affecting this type of ecosystem with great anthropogenic influence.

Substantial efforts have been devoted to developing and applying biomarkers for ecological risk assessment. Bivalve mollusks, such as mussels and oysters, are commonly used in environmental monitoring programs because of their wide geographical distribution, great sensitivity to environmental pollutants, and ability to accumulate anthropogenically derived chemicals at a high rate. Acetylcholinesterase (AChE) activity and metallothionein (MT's) content are representative specific biomarkers that indicate the presence of anticholinesterasic compounds (like organophosphorus and carbamate pesticides) and metals, respectively. The aim of this study was to evaluate AChE activity and MT's content in Crassostrea corteziensis from Boca de Camichín estuary. The results obtained here showed that AChE activity was 65% lower in oysters from Boca de Camichín than in control organisms. In contrast, MT's content in collected organisms was not statistically different from that in control organisms. AChE activity and MT's content in oysters could be used as early biomarkers of effects and exposure to pesticides and heavy metals, respectively, in aquatic environments.

PURPOSE: To describe frequency, clinical characteristics, and visual prognosis of tubercular uveitis (TBU) in a nonendemic country. METHODS: We retrospectively reviewed 3743 charts of patients with endogenous uveitis visited from 2008 to 2018 at a tertiary referral centre in Rome, Italy. We included immunocompetent patients with diagnosis of TBU. Patients were divided in two groups: patients with history of uveitis without a previous diagnosis of TBU (group A) and patients at their first episode of TB uveitis (group B). RESULTS: TBU was diagnosed in 28 (0.75%) out of 3743 patients. Twelve (42.9%) patients came from tuberculosis endemic areas. All patients received specific antitubercular treatment (ATT) and were evaluated for a mean follow-up of 3.2 ± 2.9 years. Group A showed a greater number of ocular complications when compared with group B. ATT was effective in reducing the frequency of recurrences of uveitis in patients of group B. CONCLUSION: Intraocular inflammation can be the first manifestation of tuberculosis. Our data highlight that early diagnosis and specific treatment of TBU may allow to decrease recurrences and to improve visual outcomes.
ABSTRACT
A single-use optical sensor was designed for Zn(II) determination based on the immobilisation of the colorimetric reagent 2-acetylpyridine benzoylhydrazone (2-APBH) in a polymer inclusion membrane (PIM) adhered on the surface of an inert rectangular strip of polyester (Mylar). Different components for the membrane preparation were tested and those resulting in membrane with good appearance, proper physical and optical properties and ease of preparation were selected. Factorial design 23 with three replicates of the central point was applied for the optimisation of the membrane composition. The optimal composition consisted of 2.5 g of poly(vinyl chloride) (PVC), 4 mL of tributyl phosphate (TBP) and 0.04 g of 2-APBH. The optode showed a linear dynamic range from 0.03 (detection limit) to 1 mg L-1 of Zn(II) ions with a response time of 30 min in aqueous solution at pH 6 and a relative standard deviation of 3.90% for 0.4 mg L-1 of Zn(II). The sensor exhibited good selectivity to Zn(II) over other commonly ions. It was successfully applied to the determination of Zn(II) in a water certified reference material, spiked tap water, vitamin-mineral drink, food supplement and foot health care products, as contribution to the concern about this heavy metal due to its significant role in many biological and physiological processes although toxicant at high doses.

Fish resistance to microorganisms depends basically on the immune response. Although there are several studies on the diazinon mammalian immunotoxicity, in the case of fish there are only few. The aim of present study was to evaluate the effect of diazinon on immunological parameters (relative spleen weight, splenocytes count, lysozyme activity, respiratory burst and IgM concentration) in Nile tilapia. Diazinon at sublethal concentrations (0.39 and 0.78 mg/L) did not alter RSW, splenocytes count or lysozyme activity. However, at the highest concentration tested (1.96 mg/L) diazinon significantly increased respiratory burst and IgM concentration. In summary, diazinon (and perhaps other pesticides) could alter immunological response and induce oxidative stress.

A disposable and miniaturised optical sensor based on colorimetric solid-phase extraction has been designed using poly(styrene-divinylbenzene) membrane disks modified with the colorimetric reagent pyridoxal salicyloylhydrazone to determine the aluminium concentration in aqueous solutions. The extraction of Al(III) ions by the reagent immobilised onto a disk allows the quantification directly on the adsorbent surface by a miniature portable reflectance spectrometer with an optical fibre at 434â¯nm. The optimisation of the sensing system was carried out by a fractional factorial design 33-1 considering the extraction pH, amount of ligand immobilised onto the disk and time of immobilisation as experimental factors. The linear dynamic range of the sensor response ranged from 0.18 to 2â¯mgâ¯L-1â¯Al(III) with a detection limit of 0.18â¯mgâ¯L-1 (nâ¯=â¯10), being the precision of 6.3% for 1â¯mgâ¯L-1â¯Al(III) (nâ¯=â¯10, confidence level of 95%). The proposed method was successfully applied to the analysis of aluminium in leachates from cookware, antacids and hygienic care products, as contribution to the concern about aluminium as a known systemic toxicant at high doses.

A tandem system based on the coupling of a bulk liquid membrane and a flow injection analysis for the separation, preconcentration and spectrophotometric determination of copper in saline water is presented. The ligand pyridine-2-acetaldehyde benzoylhydrazone has been used as a carrier in the liquid membrane as well as a spectrophotometric reagent for UV-VIS detection. Simultaneous and sequential experimental designs were used to optimise the chosen variables of each technique, respectively. The metal was separated and preconcentrated from the sample with an efficiency of 100.5⯱â¯0.9% and a metal preconcentration factor of 16.1. The on-line FIA determination was accomplished after metal complexation by the reagent at pH 3. A linear response was obtained in a range from 6.9 to 984.5⯵gâ¯L-1 Cu(II), providing a detection limit of 1.8⯵gâ¯L-1. Saline matrix and other metal ions were not cause of interferences with relative errors below 4.6% for 50⯵gâ¯L-1 of Cu(II) determination. The proposed tandem system was successfully tested using a TMDA-62 certified reference material providing a relative error of +â¯1.9%; it was also applied to the Cu(II) determination in coastal seawater samples with low relative errors ranging from -â¯3.8% to 0.0% (using DPASV as reference method).
ABSTRACT
In Europe, Thelazia callipaeda has been reported in Italy and France in the eyes of dogs, cats and foxes and, recently, also in humans. In southern Switzerland (Ticino), the first case of T. callipaeda in a dog was detected in 2000 and because of an increasing number of dog thelaziosis, a survey in veterinary practices was carried out. A total of 106 Thelazia-positive dogs from a retrospective analysis and from ongoing cases between 2005 and 2007 as well as five positive cats were reported. For a cross-sectional study, 529 randomly selected dogs (from six veterinary practices), to which anaesthesia was given for other medical reasons, were additionally checked for the presence of adult specimens of Thelazia in 2006: 28 dogs were found positive indicating an overall prevalence of 5.3%. Thelazia-infection was furthermore diagnosed in 7 of 126 foxes (5.6%) shot in Ticino in winter 2005-2006. Affected foxes, dogs and cats originated from the same regions up to 863m of altitude. The cats and 57.9% (55/95) of the infected dogs had never crossed the Swiss border. Collected nematodes were morphologically identified as T. callipaeda, and this diagnosis was confirmed by the analysis of a part of the sequence of the mitochondrial cytochrome c oxidase subunit 1 gene (cox1), revealing haplotype 1, the only one so far found in Europe. Animals harboured 1-23 eye worms. The most common symptoms were conjunctivitis and epiphora, while keratitis was present only in a low number of animals. Young and small sized dogs were significantly less involved than large animals and over 3 years of age. The results indicate that thelaziosis is endemic in that area.

OBJECTIVE: To analyze the frequency and methods of sedation used in the context of regional anesthesia in adults by means of a national survey. MATERIAL AND METHODS: We carried out a survey of participants at the courses of an anesthesiology training organization (Fundación Europea de Enseñanza en Anestesiología), held in Spain in 2006. The survey questionnaires asked about indications for sedation used during surgery under regional anesthesia as well as the form of administration, follow-up, and complications. RESULTS: A total of 375 questionnaires were sent out and 185 responses were received (49.3%). Sedation is always used to accompany regional anesthesia by 69.2% of the respondents; 13.5% of them discuss the technique to be used with the patient and come to an agreement. The same type of sedation, regardless of the regional block performed, is used by 49.2% of respondents, and 64.3% use a scale to evaluate the level of sedation. The most favored sedation technique is continuous infusion, followed by target controlled infusion and boluses on demand. The most commonly used technique is sedation with bolus injections. Sixty percent use a single agent and 38.9% use combinations. The most commonly reported adverse effects are variability of patient response (53.5%) and respiratory complications (27%). In cases of ineffective regional blockade, 49.2% of those surveyed switch to general anesthesia. CONCLUSIONS: Sedation is very often used to complement regional anesthesia in adult patients. Even though continuous infusion is considered to be the most appropriate form of administration, the most commonly used form is injection of boluses. Sedation with a single drug is used more frequently than drug combinations. Variability of individual response is the complication most commonly reported by the respondents.

Plasmablastic lymphoma (PBL) is a malignant, rare, and aggressive form of non-Hodgkin's lymphoma with poor response to treatment that most commonly involves the oral mucosa of immunodeficient patients. The orbit might be primarily or secondarily involved; on the other hand other pathological conditions, i.e., fungal infections, may localize in the orbit in both immunocompromised patients and drug user, which might have similar radiological features. We describe the clinical, radiological, and pathological features of an orbital plasmablastic lymphoma (PBL) in an immunocompromised HIV positive drug user patient.
ABSTRACT
Chlorpyrifos is an organophosphorous insecticide widely used in agriculture and domestic activities. However, little is known about the effect of this pesticide on the immune system of fish and other alterations of its physiological system. The aims of the present study were the evaluation of the LC(50) (lethal concentration(50)) and the potential toxicity of this substance on Nile tilapia (Oreochromis nilotucus), as well as its effect on some hematological values and phagocytic functions of this fish. Results obtained showed that chlorpyrifos does not have any effect on the following parameters: number of red blood cells, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). However, the phagocytic index and the percentage of phagocytic active cells were significantly affected, which could indicate that phagocytic parameters from Nile tilapia are more sensitive than hematological ones to assess the effect of acute intoxication with chlorpyrifos.
ABSTRACT
Temephos is an organophosphorus pesticide that is used in control campaigns against Aedes aegypti mosquitoes, which transmit dengue. In spite of the widespread use of temephos, few studies have examined its genotoxic potential. The aim of this study was to evaluate the cytotoxic, cytostatic and genotoxic effects of temephos in human lymphocytes and hepatoma cells (HepG2). The cytotoxicity was evaluated with simultaneous staining (FDA/EtBr). The cytostatic and genotoxic effects were evaluated using comet assays and the micronucleus technique. We found that temephos was not cytotoxic in either lymphocytes or HepG2 cells. Regarding the cytostatic effect in human lymphocytes, temephos (10 µM) caused a significant decrease in the percentage of binucleated cells and in the nuclear division index as well as an increase in the apoptotic cell frequency, which was not the case for HepG2 cells. The comet assay showed that temephos increased the DNA damage levels in human lymphocytes, but it did not increase the MN frequency. In contrast, in HepG2 cells, temephos increased the tail length, tail moment and MN frequency in HepG2 cells compared to control cells. In conclusion, temephos causes stable DNA damage in HepG2 cells but not in human lymphocytes. These findings suggest the importance of temephos biotransformation in its genotoxic effect.

Chest pain is one of the most important reasons of Emergency Department arrivals (5% of total). As it is not possible to rule-in all patients claiming chest pain, it has been proposed to create new departments to monitor these patients during some hours, in order to exclude or confirm an acute coronary syndrome. These departments are named Chest Pain Units (CPUs). The Chest Pain Unit has been created since June 1998 in Alessandria Hospital "SS. Antonio e Biagio e C. Arrigo". Chest Pain Unit patients presenting in Emergency Department with an unclear defined chest pain are submitted to a continuous ECG monitoring of S-T trend for 24 h. Moreover, cardiac markers such as myoglobin, mass CK-MB and Troponin-I are tested at arrival and Troponin-I is tested again serially 3, 6, 9, 18 h after the first sampling. It is really important to be able to measure these markers of myocardial damage with robust and quick methods. A point-of-care analyzer is available in our chest pain unit and enables our department to obtain results in a very short time at low cost and with quality similar to that of clinical chemistry laboratories' instruments. This easy-to-use analyzer can be run by nurses without interfering in their normal activities. The presentation of our experience will be completed by describing all patients admitted in our Chest Pain Units from January to June 1998.

The elemental analysis of 86 honeys sold in France was performed with an inductively coupled plasma atomic emission spectrometer in order to measure significant concentrations of Ag, Ca, Cr, Co, Cu, Fe, Li, Mg, Mn, Mo, P, S, Zn, Al, Cd, Hg, Ni, and Pb. Principal component analysis, correspondence factor analysis, and hierarchical cluster analysis were used to rationalize and interpret the analytical data. Crude relationships were found between the elemental profiles of the honeys and their botanical origin. Some honeys were highly polluted by heavy metals and/or other xenobiotics. Explanations for these contaminations are proposed.

A case of IgD myeloma that began with high paraproteinaemia, BJ proteinuria of type and 40% marrow plasmacellular infiltration is reported. These onset data suggested a large tumoral mass and hence a poor prognosis. On the other hand, after subjecting the patient to 4 polychemotherapy cycles (alkeran and prednisone) CM disappeared from serum and urine and bone lesion progression stopped. It is also stressed that this from presents clinical (frequent extra-osseous growth, presence of amyloidosis), laboratory (severe anaemia, renal insufficiency, BJ proteinuria) and particular prognostic features.

This study has led to two conclusions: the first is that ultrasound examinations of the pelvis are often asked for immediately after termination of pregnancy because clinicians suspect there may be complications. On the other hand these ultrasound pictures are difficult to interpret and so often, therefore, curettage is carried out which in fact is not necessary. The authors describe a prospective study carried out on 144 cases of termination of pregnancy for which pelvic ultrasound was routinely carried out following termination of pregnancy. The results of this study show that there are several types of ultrasound pictures found immediately after termination of pregnancy; these contain some that can be considered to be reassuring and others that are doubtful. The conclusion depends on the answer to several questions: is it correct to carry out routine ultrasound immediately after termination of pregnancy and has it a real practical purpose? From this can one say that it is necessary to do an ultrasound after every termination of pregnancy? If not, are there special indications for the procedure?
