Abstract
Background Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterisation by a multifactorial approach. The general purpose of this study is to evaluate the effectiveness and cost-effectiveness of the T-Control catheter versus the Foley-type catheter in patients with Acute Urine Retention (AUR). Study design This is a pragmatic, open, multicentre, controlled clinical trial with random allocation to the T-Control catheter or a conventional Foley-type catheter in patients with AUR. Endpoints The magnitude of infections will be analysed as a primary endpoint. While as secondary endpoint, the following will be analysed: rate of symptomatic and asymptomatic infections; days free of infection; quality of life-related to self-perceived health; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterisation's healthcare resources; level of satisfaction and workload of health professionals and acceptability of the T-Control device as well as the patient experience. Patients and methods Eligible patients are male adults aged ≥50 years, with AUR and with an indication of bladder catheterisation for at least 2 weeks. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 2 weeks later, plus 2 weeks after this time when the patient will be called for an in-depth interview.

Abstract
Summary Objective. The association of allergic conjunctivitis (AC) with rhinitis and/or asthma is poorly understood. The objective of this study was to apply the Consensus Document for Allergic Conjunctivitis (DECA) criteria for the classification of AC to a population of patients with AC to assess the association between the severity and duration of AC and rhinitis and/or asthma. Methods. Patients with ocular symptoms of AC who participated in the 'Alergológica 2015' study were included. The demographics, classification according to the DECA criteria, etiology, and comorbidities were evaluated by age groups (less or equal than 14 and greater than 14 years). Results. A total of 2,914 patients (age range, 1-90 years) were included in the "Alergológica 2015" study. Of these, 965 patients (33.1%) were diagnosed with AC (77.5% > 14 years). AC was classified as severe, moderate, or mild in 1.8%, 46.4%, and 51.8%, respectively; and as intermittent or persistent in 51.6% and 48.4% of the patients. AC alone occurred in 4% of patients. AC was mainly associated with rhinitis (88.4%), asthma (38.2%), food allergy (8.3%) and atopic dermatitis (3.5%). In allergic respiratory disease rhinitis preceded AC and asthma developed later. The severity and duration of AC was significantly associated with severity and duration of rhinitis (p less than 0.001 for both age groups) and asthma (p less than 0.001 only in adults). Conclusions. The application of the new DECA classification for AC reveals a direct relationship between AC, rhinitis and asthma respect to severity and duration. These relationships suggest that AC should be considered an integral part of the "one airway, one disease" hypothesis.

Abstract
The shortage of suitable organ donors for transplantation has stimulated the use of organs from donors with transmissible infections such as Chagas disease in noninfected recipients. A case is described of liver transplantation from an anti-Trypanosoma cruzi-positive donor to a noninfected recipient who showed favorable evolution despite not having undergone preemptive therapy.

Abstract
Nasal hyperreactivity is the abnormal reaction of nasal tissue to a stimulus that is innocuous to most people. This response is caused by dysregulation of the autonomic nervous system at various levels of the nasal autonomic reflex arc. Various stimuli (methacholine, histamine, adenosine 5'-monophosphate, cold air, mannitol, rapsaicin, phentolamine, and distilled water) have been used in an attempt to find the test that most reliably differentiates between healthy individuals and patients and also between different types of rhinitis. Despite the small number of publications available, in the present review, we provide an update on current nonspecific nasal provocation techniques. The studies published to date are not comparable: the stimuli applied act through different mechanisms and are used to assess different pathways, and the methodologies differ in terms of selection of participants, concentrations used, and assessment of response (criteria for positivity). Given the limited use of nonspecific nasal provocation tests in routine clinical practice, we believe that more studies are warranted to address the research issues we present at the end of the present review, for example, the need to standardize the methodology for each test or even the clinical benefits of knowing whether or not a patient has nasal hyperreactivity.

Abstract
Allergic conjunctivitis (AC) is an inflammatory disease of the conjunctiva caused mainly by an IgE-mediated mechanism. It is the most common type of ocular allergy. Despite being the most benign form of conjunctivitis, AC has a considerable effect on patient quality of life, reduces work productivity, and increases health care costs. No consensus has been reached on its classification, diagnosis, or treatment. Consequently, the literature provides little information on its natural history, epidemiological data are scarce, and it is often difficult to ascertain its true morbidity. The main objective of the Consensus Document on Allergic Conjunctivitis (Documento dE Consenso sobre Conjuntivitis Alérgica [DECA]), which was drafted by an expert panel from the Spanish Society of Allergology and Spanish Society of Ophthalmology, was to reach agreement on basic criteria that could prove useful for both specialists and primary care physicians and facilitate the diagnosis, classification, and treatment of AC. This document is the first of its kind to describe and analyze aspects of AC that could make it possible to control symptoms.

Abstract
CASE REPORT A 67 year-old male seen for a longstanding corneal-conjunctival tumor. TREATMENT topical interferon α2b (IFN-α2b) 10 U/ml. A significant increase in lesion size was observed after 8 weeks. A surgical excision with cryotherapy was then performed. Pathological examination confirmed the diagnosis of squamous cell carcinoma. At this time the patient was found to have a positive HIV serology. DISCUSSION Conjunctival intraepithelial neoplasia (CIN) is a pre-cancerous lesion of the ocular surface. Medical treatment of CIN is essentially with IFN-α2b due to its antiviral/antitumor properties. In patients with HIV, treatment response could be paradoxical. We recommend serology for HIV before treatment with topical IFN-α2b.

Abstract
A common cause for surgical failure of primary hyperparathyroidism (pHPT) is the non-detection of an ectopic adenoma during the intervention. We present a case of a patient with pHPT in whom an ectopic gland was found in the right retropharyngeal space by means of a double phase (99m)Tc-methoxy-isobutyl-isonitrile ((99m)Tc-MIBI) scintigraphy and early SPECT-CT after several surgeries and imaging tests. The addition of a tomography to the planar scintigraphy increases its sensitivity and improves pathological parathyroid glands localization. The hybrid imaging is sometimes essential to obtain surgical success, as in the case of ectopic adenomas.

Abstract
BACKGROUND While researchers have attempted to address the difficulties of diagnosing affective disorders in the intellectually disabled population, diagnosing bipolar disorder in an individual with severe intellectual disability (ID) remains a challenge. The aim of this study was to identify what symptoms can predict a diagnosis of mania in the intellectually disabled population. METHODS Three groups of persons with ID participated in this study: (1) individuals with a bipolar diagnosis who were currently manic; (2) individuals with an Axis I diagnosis other than bipolar disorder; and (3) individuals without an Axis I diagnosis. Two recognized measures of mania (i.e. Diagnostic Assessment for the Severely Handicapped-Revised and Parent Version of Young Mania Rating Scale) were used to evaluate symptoms of mania. A logistical regression procedure was conducted on mania items to identify which items correctly identify persons with ID who were currently manic. RESULTS Psychomotor agitation, decreased sleep, changes in mood and aggression were significantly related to the diagnosis of mania. Further, psychomotor agitation and disturbed sleep were significant predictors of a diagnosis of mania. CONCLUSIONS Problems of sleep and psychomotor agitation should alert clinicians that further assessment of bipolar symptomatology is warranted. Focusing on observable behaviours based on Diagnostic and Statistical Manual of Mental Disorder-IV criteria can be useful in formulating a diagnosis of bipolar disorder in persons with ID.

Abstract
Twin and family studies have demonstrated that a large part of a population's variance in bone mineral density (BMD) is attributable to genetic factors. A polymorphism in the collagen type I alpha1 (COLIA1) gene has recently been associated with low bone mass and fracture incidence. We analyzed the relationship between COLIA1 gene polymorphism, lumbar spine and hip BMD, and fracture prevalence in a population of 319 postmenopausal women classified by WHO standards, including 98 nonosteoporotic women (NOPW) and 221 osteoporotic postmenopausal women (OPW), divided into 139 osteoporotic women without fracture (OPWnF) and 82 osteoporotic women with fracture (OPWwF). The COLIA1 genotype was assessed by polymerase chain reaction and BalI endonuclease digestion. Genotype frequencies for the total group were 49.2% GG homozygotes, 39.5% GT heterozygotes, and 11.3% TT homozygotes. We found significant differences in the percentage of homozygous TT between NOPW and OPW (6.1% and 13.6%, respectively). Significantly, the occurrence of genotype TT in OPWnF was 6.2%, and 28% in OPWwF. We observed no associations between the COLIA1 genotype and lumbar spine and hip BMD. The prevalence of fractures varied significantly by genotype: GG, 26.1%; GT, 15.9%; and TT, 58.3%. Logistic regression analysis of fracture prevalence showed that, for prevalent fractures, the women with the TT genotype had a 5.9-fold increased risk when compared with the other genotypes (GG + GT). When prevalence was adjusted for age, body mass index, and BMD, the fracture risk was 4.8 for the TT group vs. the genotype GG, whereas it was 0.6 for the GT genotype. In conclusion, we found the COLIA1 Sp1 TT genotype to be associated with an increased fracture risk in postmenopausal women. Interestingly, this genotype-dependent risk could not be explained completely by BMD differences.

Abstract
Plasma methadone concentrations and its main metabolite D,L-2-ethylidiene-1,5-dimethyl-3,5-diphenylpyrrolidine (EDDP) were determined in 93 patients under methadone maintenance treatment to assess their relationship with heroin use and opioid withdrawal symptoms. Neither plasma concentrations of methadone nor EDDP were significantly different when patients that used heroin in last 3 months were compared with those testing negative for this drug (methadone, 355 +/- 217 versus 369 +/- 216 ng/ml, t = 0.29, P = NS; EDDP, 49 +/- 28 versus 54 +/- 40 ng/ml, t = 0.51, P = NS). No correlation between opioid withdrawal scale scores and plasma concentrations of methadone (r = 0.02, P = NS) and EDDP (r = -0.14, P = NS) was found. Therapeutic drug monitoring during methadone maintenance seems to be useful for assessing compliance with treatment but not for predicting heroin use and subjective withdrawal symptoms.

Abstract
The simultaneous administration of cocaine and alcohol implies a pharmacological interaction at pharmacodynamic and pharmacokinetic levels. The latter involves an alteration of cocaine kinetics and metabolism, as well as the biosynthesis of newly active metabolites, such as cocaethylene. Cocaethylene is metabolized along the same pathways as cocaine. Its detection in biological samples indicates the combined consumption of cocaine and alcohol. From epidemiological and toxicological data, it has been suggested that the combination of alcohol and cocaine produces an increased toxicity in addition to behavioral changes. There has been some debate regarding the contribution of cocaethylene to this rise of toxicity. Its pharmacological and toxicological profile is very similar to cocaine. During the interaction of both substances, the rise in cocaine plasma concentrations can explain many of cardiovascular and behavioral effects observed. The contribution of cocaethylene to the interaction is probably minor; its effects are likely additive to those of cocaine. Perhaps its longer elimination half-life can help in understanding long-lasting effects of the alcohol-cocaine combination.

Abstract
The effects of 100 mg of intranasal cocaine in acute alcohol intoxication (0.8 g/kg) were evaluated in eight experienced and nondependent healthy volunteers in a double-blind double-dummy, controlled, randomized, crossover clinical study. The combination of alcohol and cocaine produced greater increases in HR, rate-pressure product and pleasurable-related subjective effects (euphoria, well-being) compared with the effects of cocaine. The drug combination reduced the alcohol-induced sedation, but feelings of drunkenness were not significantly counteracted. Cardiovascular changes induced by the combination condition caused an increase in myocardial oxygen consumption that may be related to an increased risk of cardiovascular toxicity. The augmented subjective euphoria may explain why the drug combination is more likely to be abused than is cocaine or alcohol alone. Plasma cortisol concentrations were significantly higher after concomitant alcohol and cocaine use than with cocaine alone. The administration of cocaine did not alter alcohol-induced hyperprolactinemia. Although cocaine produced a slight decrease in plasma concentrations of prolactin when administered alone, it did not antagonize the effects of alcohol on prolactin secretion when alcohol and cocaine were given simultaneously. The combination increased cocaine and norcocaine plasma concentrations, and induced the synthesis of cocaethylene and norcocaethylene. The enhancement of cocaine effects in the drug combination may be due to initially increased cocaine plasma levels followed by the additive effect of cocaethylene, although a pharmacodynamic interaction could not be excluded.

Abstract
The results obtained in a study of seroprevalence by means of ELISA and immunoblot with crude larval extracts of Anisakis simplex using 1008 human sera from Spanish people showing no clinical suspicion of anisakidosis are given. For the evaluation of the results obtained by ELISA the Diagnostic Index (DI) was used, as the ratio between the optical density resulting from the test serum and the optical density of the negative control. Forty-seven sera showed DIs between 1.5 and 2, and 14 sera were greater than 2. After comparison of the immunoblot analysis with the immunorecognition pattern of a human anisakidosis reference serum, a diagnostic criterion could be established for those sera that, at a 1/100 dilution, showed a DI by ELISA greater than 1.5. Seven of 14 selected sera with DIs in ELISA higher than 1.3 showed anti-Anisakis specific IgE antibodies by RAST fluoroimmunoassay.

Abstract
Cocaethylene is an active metabolite produced when cocaine is consumed jointly with ethanol. The development of analytical techniques for determining cocaethylene and other cocaine metabolites is highly relevant for pharmacokinetic and toxicology studies of the cocaine and alcohol interaction in humans. The gas chromatography/mass spectrometry (GC/MS) method here reported is based on a single solid-phase extraction together with deuterated internal standards previously added to urine, followed by derivatization with pentafluoropropionic anhydride (hydroxyl and amine functions) and 1,1,1,3,3,3 hexafluor-2-propanol (carboxylic acid function) and injection into a capillary GC system coupled to a mass spectrometric detector in the selected ion monitoring acquisition mode. A sensitivity of 1-2 ng ml-1 for the quantitative analysis of cocaine and its main metabolites (ecgonine methyl ester, benzoylecgonine, cocaethylene and norcocaine) was achieved. In addition, some other minor metabolites were easily extracted and detected.

Abstract
Thermal degradation of some substances due to high temperature at the injection port and/or the type of injection technique used may limit the usefulness of gas chromatography with conventional detectors or coupled to mass spectrometry. To minimize thermal degradation of cocaine and its metabolites, chromatography was performed using two different insert liners and a cool on-column inlet. When using a packed liner, marked degradation of all compounds was observed. The degradation process was reduced by the use of an open liner and, when the cool on-column inlet was employed, essentially no degradation occurred.

Abstract
The influence of pineal gland function and of melatonin during pregnancy upon sexual maturation of female offspring in rats was examined. The following groups of Wistar rats were studied: (A) control, (B) melatonin treated (250 micrograms/100 g.b.w. per day) throughout pregnancy, and (c) pinealectomized (pin-x). Melatonin was injected subcutaneously 2 hr before lights off. All groups were housed in 12-hr L:12-hr D. The female offspring were observed until the onset of puberty, and blood samples were collected 5.5 hr after lights off under red light for melatonin and LH determinations by RIA. Ovary, pineal, and pituitary gland as well as body weights were recorded. The offspring of melatonin-treated rats showed later vaginal opening than did those of the other two groups (P less than 0.05 vs. control and P less than 0.01 vs. pin-x offspring), which was accompanied by a lower LH concentration, 0.42 + 0.05 ng LH/ml, showing statistically significant differences with the control levels [1.00 + 0.22 ng LH/ml (P less than 0.05)] and with the pin-x group [1.16 + 0.22 ng LH/ml (P less than 0.05)]. The percentage of rats in proestrus was higher in the offspring of pin-x rats (78.6%; P less than 0.01) compared to control offspring (30%) and offspring of melatonin-treated rats (11.8%). The concentrations of melatonin, 5.5 hr after darkness, were not significantly different among groups. No differences were observed in the body, ovarian, and pineal weights of the studied offspring. The pituitary weight was significantly lower (P less than 0.05) in the offspring of pin-x rats than in the other two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A recombinant hepatitis B vaccine was administered to high-risk hospital personnel by intramuscular (20 micrograms) or intradermal (2 micrograms) injections for the primary immunization (n = 69) with three doses and booster immunization (n = 51) with one dose. Basic vaccination performed intramuscularly gave rise to significantly higher seroconversion levels (97.2% versus 78.1%) and geometric mean titres of antibody (1649 versus 126 IUl-1) as compared with the intradermal route. Intradermal administration did not boost antibody titres in patients previously vaccinated intradermally. Adverse reactions were not serious or severe. The intramuscular route is recommended as the procedure of choice when vaccinating against hepatitis B.
