Prevalencia del tabaquismo pasivo en pediatría

Objetivo: estudiar la prevalencia de la exposición al humo de tabaco ambiental (HTA) de los niños asistidos durante el invierno del año 2007. Evaluar si la exposición al HTA se relaciona con determinada evolución en los pacientes internados por patología respiratoria. Material y método: se realizó un interrogatorio dirigido mediante un cuestionario escrito a los padres de 559 niños para determinar si los mismos estaban expuestos al HTA por padres, convivientes o cuidadores. Se los dividió en 4 grupos: Grupo 1: niños internados por patología respiratoria. Grupo 2: niños internados por patologías no respiratorias. Grupo 3: niños que consultaron ambulatoriamente al hospital. Grupo 4: niños que consultaron ambulatoriamente al sector privado. Se analizó en el grupo 1 a los niños cuya internación fue mayor a 10 días (internación prolongada) y a los que requirieron cuidados intensivos. Resultados: Grupo 1: 103 niños; grupo 2: 112 niños, grupo 3: 100 niños; grupo 4: 244 niños. La exposición al HTA fue: grupo 1, 77% (p=0.000); grupo 2, 52%; grupo 3, 50%; grupo 4, 33%. Al comparar los 2 grupos de pacientes internados, (1 y 2), observamos que la exposición al HTA fue significativamente mayor en el grupo 1 (p=0.0001). Al analizar los grupos de pacientes atendidos en forma ambulatoria en el sector publico (Grupo 3), y en el sector privado (Grupo 4), observamos que hubo una exposición al HTA significativamente mayor (p=0.002) en los pacientes del Grupo 3. El 90% de los niños que requirieron internación prolongada (17 de 19 niños) tenían antecedentes de exposición al HTA. El 80% de los que requirieron terapia intensiva (4 de 5 niños) estuvieron expuestos al HTA. Conclusiones: el grupo de pacientes internados por patología respiratoria fue el más expuesto a HTA. Además la mayoría de los pacientes con internación prolongada o que requirieron cuidados intensivos, presentaban como antecedente la exposición al HTA. Los niños que consultaron al sistema público presentaron mayor exposición al HTA que aquellos que lo hicieron al sistema privado.Objective: to study the prevalence of exposure to environmental tobacco smoke (ETS) of children assisted during the Winter of year 2007, and to evaluate if the exposure to ETS was related to a specific outcome in the group of patients hospitalized due of respiratory pathology

During the interview, the patient stated having had contact with cats, and a history of conjunctivitis comes up. These led to the diagnosis of Parinaud syndrome caused by cat scratch disease

Immunodetection of aquaporin 5 in sheep salivary glands related to pasture vegetative cycle.

Mammalian aquaporins (AQPs) are a family of at least 13 integral membrane proteins expressed in various epithelia, where they function as channels to permeate water and small solutes. AQP5 is widely expressed in the exocrine gland where it is likely involved in providing an appropriate amount of fluid to be secreted with granular contents. As regards AQP5 expression in the salivary glands, literature is lacking concerning domestic animal species. This study was chiefly aimed at immunohistochemically investigating the presence and localization of AQP5 in sheep mandibular and parotid glands. In addition, AQP5 immunoreactivity was comparatively evaluated in animals fed with forage containing different amounts of water related to the pasture vegetative cycle, in order to shed light on the possible response of the gland to environmental modifications. Moderate AQP5-immunoreactivity was shown at the level of the lateral surface of mandibular serous demilune cells, not affected by the pasture vegetative cycle or water content. On the contrary, the parotid gland arcinar cells showed AQP5-immunoreactivity at the level of apical and lateral plasma membrane, which was slight to very strong, according to the pasture vegetative development and interannual climatic variations. AQP5 expression is likely due to its involvement in providing appropriate saliva fluidity. Indeed, the lowest AQP5 immunoreactivity was noticed when food water content increased.

Korištenje povlačne podvodne kamere za procjene škampa, hlapića i morskog pera u Jadranskom moru

Norway lobster, Nephrops norvegicus, is of great commercial importance throughout the NE Atlantic and Mediterranean, where it lives in burrows within muddy sediments. In several European countries it is assessed by means of towed underwater TV techniques. These are particularly suited to N. norvegicus because, for a number of reasons, the application of common fishery-dependent stock-assessment methods is not thorough for this species. The TV-based methodology relies on the fact that a known surface area of seabed is visually assessed and the number of N. norvegicus burrows, whose features are distinct, can be counted and their inhabitants quantified. It follows that, in theory, the same can be done for other organisms or key ecological features which appear on the footage. This study reports the results of the underwater television surveys (2009 and 2010) carried out jointly by Italy and Croatia in the Pomo/Jabuka pits, an area of the Adriatic Sea important for its N. norvegicus fishery and its hake nursery grounds. The obtained footage allowed quantification of the density of N. norvegicus in the area and the acquisition of estimates of the abundances of the squat lobster, Munida rutllanti and the sea pen Funiculina quadrangularis. The concurrent quantification of trawling activity from the footage has allowed us to place our results in the context of an ecosystem approach to fisheries management.Škamp ( Nephrops norvegicus ) je izuzetno važna gospodarska vrsta koja obitava u rupama u muljevitom sedimentu diljem sjeverno-istočnog Atlantika i Mediterana. Obzirom da uobičajene metode procjene bioloških resursa koje se zasnivaju na ribolovu nisu u potpunosti pogodne za ovu vrstu, nekoliko Europskih zemalja procjene populacije škampa obavlja korištenjem povlačne podvodne kamere. Ova metodologija bazira se na činjenici da škamp u sedimentu iskapa rupe karakterističnog izgleda koje se determiniraju i prebrojavaju vizualnim pregledom snimke dobivene povlačenjem podvodne kamere preko određene površine morskog dna. Teoretski, ova metodologija se može primijeniti i za procjene drugih vrsta ili ekoloških parametara koji su zabilježeni na snimkama. Ova studija iznosi rezultate istraživanja podvodnom kamerom (2009. i 2010. godine) koje su zajednički proveli Italija i Hrvatska na području Jabučke kotline u Jadranskom moru. Ovo područje koje se intenzivno gospodarski iskorištava značajno je kao glavno mrijestilište i rastilište većeg broja pridnenih vrsta, posebno škampa i oslića ( Merluccius merluccius ) Na osnovu dobivenih snimki izrađena je procjena brojnosti i biomase škampa, kao i procjena brojnosti hlapića ( Munida rutllanti ) i morskog pera ( Funiculina quadrangularis ). Istodobna procjena tragova koćarenja zabilježenih na snimkama omogućila nam je da ove rezultate stavimo u kontekst ekosustavnog pristupa gospodarenju bioloških resursa mora

Facultad de Odontología; Argentina.Objective:To determine the prevalence of oral human papillomavirus (HPV) in the population of Córdoba, Argentina and its association with other risk factors.Methods:A sample of 401 volunteers over 18 years, representative of Cordoba city population, was selected. Using a questionnaire, we collected sociodemographic data including the use of tobacco, alcohol, and mate consumption. Two biological samples were taken from each individual, whole mouth saliva and a scraping of the posterior border of the tongue. HPV was determined by polymerase chain reaction using MY09/11 primers. Statistical associations were analyzed using χ2 test.Results:Prevalence of HPV in the population was of 3% (13/401). The mean age of HPV-positive cases was 42 years with a range of 20?85; 54% were females. Among the 13 cases whose saliva was positive for HPV, only 7 (54%) had HPV-DNA in the tongue scraping. All identified genotypes were of low risk and HPV11 was the most frequent type in 62% of positive cases. None of the positive subjects exhibited oral lesions compatible with HPV infection. Ten (77%) of the HPV-positive subjects exhibited lesions in the oral mucosa, mostly related to chronic mechanical irritation (CMI) (odds ratio 3, 95% confidence interval: 1.01?8.97, p < 0.05). Fifty-four percent of HPV-positive individuals were light smokers and consumed alcohol moderately. The combination of both habits was observed in 31%. Sixty-two percent drank mate at high water temperatures. No differences were detected in the sexual behavior or in the reported number of sexual partners between HPV-positive and -negative subjects.Conclusion:The overall prevalence of oral HPV in adults was 3%; only the low-risk genotypes were detected and no association with other risk factors for oral cancer was found. However, an association with CMI of the oral mucosa was noted. The saliva sample proved to be a simple, efficient, and well-tolerated method suitable for screening for HPV, and more cases were detected in saliva compared with tissue scrapings.http://journals.sagepub.com/doi/10.1177/2057178X18757334info:eu-repo/semantics/publishedVersionFil: Criscuolo, María Inés.

Effects of Aversive Stimuli on Prospective Memory. An Event-Related fMRI Study

Prospective memory (PM) describes the ability to execute a previously planned action at the appropriate point in time. Although behavioral studies clearly showed that prospective memory performance is affected by the emotional significance attributed to the intended action, no study so far investigated the brain mechanisms subserving the modulatory effect of emotional salience on PM performance. The general aim of the present study was to explore brain regions involved in prospective memory processes when PM cues are associated with emotional stimuli. In particular, based on the hypothesised critical role of the prefrontal cortex in prospective memory in the presence of emotionally salient stimuli, we expected a stronger involvement of aPFC when the retrieval and execution of the intended action is cued by an aversive stimulus. To this aim BOLD responses of PM trials cued by aversive facial expressions were compared to PM trials cued by neutral facial expressions. Whole brain analysis showed that PM task cued by aversive stimuli is differentially associated with activity in the right lateral prefrontal area (BA 10) and in the left caudate nucleus. Moreover a temporal shift between the response of the caudate nucleus that preceded that of aPFC was observed. These findings suggest that the caudate nucleus might provide an early analysis of the affective properties of the stimuli, whereas the anterior lateral prefrontal cortex (BA10) would be involved in a slower and more deliberative analysis to guide goal-directed behaviour
