Abstract
AIM AND METHOD The aim of this study was to describe the clinical characteristics and outcome of pandemic influenza A H1N1/2009 (pH1N1) infection, in a retrospective cohort of pediatric patients with kidney and/or liver transplant and confirmed pH1N1 infection from June to December 2009, diagnosed in 2 Spanish teaching hospitals. RESULTS Forty-nine patients were included. Pneumonia was diagnosed in 4 patients (8.2%), and 3 of them required respiratory support. There were no related deaths. CONCLUSION Antiviral treatment within 48 h was associated with a lower likelihood of pneumonia (0/38, 0%) than treatment started after 48 h (4/11, 36.3%) (P < 0.01).

Abstract
In this work, the degradation of anionic and non-ionic surfactants in agricultural soil amended with sewage sludge is reported. The compounds analysed were: linear alkylbenzene sulphonates (LAS) with a 10-13 carbon alkylic chain, and nonylphenolic compounds (NPE), including nonylphenol (NP) and nonylphenol ethoxylates with one and two ethoxy groups (NP1EO and NP2EO). The degradation studies were carried out under winter (12.7°C) and summer (22.4°C) conditions in Andalusia region. The concentration of LAS was reduced to 2% of the initial concentration 100 day after sludge-application to the soil. The half-life time measured for LAS homologues were ranged between 4 and 14days at 12.7°C and between 4 and 7 days at 22.4°C. With regard to NPE compounds, after 8 and 4days from the beginning of the experiment at 12.7 and 22.4°C, respectively, their concentration levels were increased to 6.5 and 13.5mg/kgdm (dry matter) as consequence of the degradation of nonylphenol polyethoxylates. These concentration levels were reduced to 5% after 63 and 70 days for 12.7°C and 22.4°C, respectively. The half-life times measured for NPEs were from 8 to 16 days at 12.7°C and from 8 to 18 days at 22.4°C. Environmental risk assessment revealed that for LAS homologues no environment risk could be expected after 7 and 8 days of sludge application to the soil for 22.4 and 12.7°C, respectively; however, potential toxic effects could be observed for the nonylphenolic compounds during the first 56 days after sludge application to the soil.

Abstract
In this work the effectiveness of membrane bioreactors as advanced treatment on the removal of emergent and priority organic compounds in wastewater treatment plants has been evaluated during a one-year monitoring study. The studied wastewater treatment plant operates with flat sheet and hollow fibre membranes in two parallel lines. Moreover, a reverse osmosis module connected in series after the hollow fibre membrane was evaluated for one month. Comparison of membrane bioreactor and conventional activated sludge treatment was also investigated, as well as the influence of the physicochemical properties of the compounds on the removal rates achieved. Sixteen pharmaceutical compounds belonging to seven therapeutic groups and eight priority organic pollutants, including linear alkylbenzene sulfonates, nonylphenol and its ethoxylates and phthalate, were monitored. The highest mean concentrations corresponded to priority organic pollutants (309 μg L(-1) of linear alkylbenzene sulfonate C(12)) followed by pharmaceutical compounds (24.5 μg L(-1) of ibuprofen). No significant difference of effectiveness was found among flat sheet and hollow fibre membranes. However, an improvement was obtained with the addition of a reverse osmosis module for most of the compounds. Biodegradation has been shown as the main route involved in the removal of organic compounds during both technologies.

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 Limited published evidence shows oral desensitization to be a potential intervention option for cow's milk protein (CMPs) allergy. OBJECTIVE The aim of this study was to evaluate the safety and efficacy of oral desensitization in 2-year-old children with cow's milk allergy, as a treatment alternative to elimination diet. METHODS A total of 60 children aged 24-36 months with IgE-mediated allergy to CMPs were included in this multi-center study and were randomized into two groups. Thirty children (group A: treatment group) began oral desensitization immediately, whereas the remaining 30 (group B: control group) were kept on a milk-free diet and followed-up for 1 year. RESULTS After 1-year follow-up period, 90% of the children in group A had become completely tolerant vs. 23% of the children in group B. In group A, cow's milk skin reactivity and serum-specific IgE to milk and casein decreased significantly from the initial assessment, whereas group B showed no significant change after 1 year of follow-up. Twenty-four patients (80%) developed some reaction during the treatment period: 14 children developed moderate reaction (47%) and 10 mild reaction (33%). The most common manifestations were urticaria-angioedema, followed by cough. CONCLUSIONS AND CLINICAL RELEVANCE In this study, oral desensitization was found to be effective in a significant percentage of 2-year-old children with cow's milk allergy. Oral desensitization appears to be efficacious as an alternative to elimination diet in the treatment of 2-year-old children with cow's milk allergy. The side-effect profile appears acceptable but requires further study.

Abstract
Gambierol is a marine polyether ladder toxin derived from the dinoflagellate Gambierdiscus toxicus. To date, gambierol has been reported to act either as a partial agonist or as an antagonist of sodium channels or as a blocker of voltage-dependent potassium channels. In this work, we examined the cellular effect of gambierol on cytosolic calcium concentration, membrane potential and sodium and potassium membrane currents in primary cultures of cerebellar granule cells. We found that at concentrations ranging from 0.1 to 30 microM, gambierol-evoked [Ca(2+)]c oscillations that were dependent on the presence of extracellular calcium, irreversible and highly synchronous. Gambierol-evoked [Ca(2+)]c oscillations were completely eliminated by the NMDA receptor antagonist APV and by riluzole and delayed by CNQX. In addition, the K(+) channel blocker 4-aminopyridine (4-AP)-evoked cytosolic calcium oscillations in this neuronal system that were blocked by APV and delayed in the presence of CNQX. Electrophysiological recordings indicated that gambierol caused membrane potential oscillations, decreased inward sodium current amplitude and decreased also outward IA and IK current amplitude. The results presented here point to a common mechanism of action for gambierol and 4-AP and indicate that gambierol-induced oscillations in cerebellar neurons are most likely secondary to a blocking action of the toxin on voltage-dependent potassium channels and hyperpolarization of sodium current activation.

Abstract
Among the emerging environmental contaminants, pharmaceutically active compounds have become a growing public concern because of their potential to cause undesirable ecological and human health effects. Doñana Park (South of Spain) includes a mosaic of unique ecosystems known around the world which is particularly affected by the quality of the incoming flowing water. This study reports the presence of a number of priority pharmaceuticals in wastewater and surface water samples from Doñana watersheds. In general, ibuprofen, naproxen, salicylic acid, propranolol, caffeine and gemfibrozil were the compounds most frequently found in all locations, in the range of ng/L to microg/L. Carbamazepine, with high potential risk to the environment, was also detected, although only in a few water samples. The main results are: (i) pharmaceuticals, as water pollutants, are continually discharged into Doñana water bodies and, owing to their biological activity, could lead to adverse effects in this outstanding aquatic ecosystem; (ii) wastewater treatments implemented in the area are insufficient to remove pharmaceuticals; and (iii) therefore, there is a requirement for better wastewater treatments in this natural area to reduce or avoid the presence of organic pollutants in general and pharmaceutical active compounds in particular. To the best of our knowledge, these data constitute the first measurements of pharmaceutical compounds in water not only from the protected area of Doñana Park but also from other Natural or National Parks in the world.

Abstract
For reasons of religious belief, Jehova's Witnesses do not accept blood transfusions or the infusion of blood products. In situations in which severe, life-threatening anemia develops, patient refusal to receive a transfusion can create serious ethical and legal problems. The principle of patient autonomy, which implies the freedom to accept or reject treatment, comes into conflict with the physician's obligation to safeguard the patient's life using all means possible. We report 2 cases of severe anemia in Jehova's Witnesses. One was due to menorrhagia and the other to postpartum bleeding. The physician should be aware of alternatives to infusion of blood products and know how to cope with an unexpected critical event in these patients. The measures we took were effective in our patients. In the case of menorrhagia, hormone treatment is effective when the woman wishes to preserve the ability to conceive and avoid surgery (endometrial ablation and hysterectomy). In postpartum bleeding refractory to conservative treatment, selective embolization of bleeding vessels may make it unnecessary to resort to more aggressive treatment, such as obstetric hysterectomy.

Abstract
In the present work, the concentrations of the organic pollutants nonylphenol (NP) and nonylphenol mono- and diethoxylates (NP1EO and NP2EO, respectively) in primary, secondary, mixed, aerobically-digested, anaerobically-digested, dehydrated, compost and lagoon sludge samples from different sludge treatments have been evaluated. Toxicological risk assessment of these compounds in sludge and sludge-amended soil has also been reported. NP, NP1EO and NP2EO were monitored in sludge samples obtained from treatment plants located in Andalusia (south of Spain) based on anaerobic treatments (11 anaerobic-digestion wastewater treatment plants and 3 anaerobic wastewater stabilization ponds) or on aerobic treatments (3 aerobic-digestion wastewater treatment plants, 1 dehydration treatment plant and 2 composting plants). The sum of NP, NP1EO and NP2EO (NPE) concentrations has been evaluated in relation to the limit value of 50 mg/kg set by the European Union Sludge Directive draft published in April 2000 (Working Document on Sludge). In most of the samples, NP was present at higher concentration levels (mean value 88.0 mg/kg dm) than NP1EO (mean value 33.8 mg/kg dm) and NP2EO (mean value 14.0 mg/kg dm). The most contaminated samples were compost, anaerobically-digested sludge, lagoon sludge and aerobically-digested sludge samples, which contained NPE concentrations in the ranges 44-962 mg/kg dm, 8-669 mg/kg dm, 27-319 mg/kg dm and 61-282 mg/kg dm, respectively. Risk quotients, expressed as the ratios between environmental concentrations and the predicted no-effect concentrations, were higher than 1 for NP, NP1EO and NP2EO in the 99%, 92% and 36% of the studied samples, respectively; and higher than 1 in the 86%, 6% and 2%, respectively, after sludge application to soil, leading to a significant ecotoxicological risk mainly due to the presence of NP.

Abstract
INTRODUCTION Tumors of the pituitary stalk are rare and their diagnosis is sometimes difficult. CASE REPORT We report a case of a primary lymphoma of the pituitary stalk in a 78-year-old patient. To our knowledge, only seven similar cases have been previously published: prominent symptoms were headache, fatigue and diplopia; biologically, anterior pituitary low secretion or hyperprolactinemia were found in the majority of cases; regarding the imaging, only three patients presented an initial and isolated lesion of the stalk; histological evidence was obtained by a trans-sphenoidal biopsy in case of hypothalamic or pituitary associated lesion or by a trans-cranial biopsy in the event of an isolated lesion. As an alternative, a lumbar puncture could be performed; although less invasive, its diagnostic performance is lower. CONCLUSION Current treatment relies on chemotherapy with intravenous methotrexate associated with intrathecal methotrexate infusion if cerebrospinal showed abnormal cells. Unfortunately, the results remain poor with a median survival of 9 months.
