Rasgo de zónula anterior larga, lecciones aprendidas acerca de una infrecuente forma de cierre angular secundario: comunicación de un caso / Long anterior zonule trait, lessons learned about an uncommon form of secondary angle closure: A case report

Una mujer de raza negra de 62 años de edad que presentaba glaucoma crónico de ángulo estrecho no controlado en tratamiento con tres fármacos fue sometida a faco-esclerectomía profunda no perforante (facoEPNP) de su ojo izquierdo (OI). Durante la cirugía se puso de manifiesto que presentaba rasgo de zónula larga. Precisó goniopunción y desbridamiento de la ampolla posteriormente, presentando una sinequia de iris en la goniopunción que pudo ser reducida de forma conservadora. Este rasgo debe sospecharse en aquellos pacientes que presentan un ángulo estrecho combinado con un síndrome de dispersión pigmentaria. El manejo de la hipertensión ocular y el glaucoma que puede aparecer asociado a este rasgo no está protocolizado. En esta comunicación se reflexiona acerca de la mejor actuación ante esta infrecuente forma de glaucoma.(AU)

A 62-year-old black woman with uncontrolled chronic narrow-angle glaucoma on 3-drug therapy underwent phaco-non-perforating deep sclerectomy of her left eye. During surgery it was revealed that she had long zonule trait. She later required goniopuncture and conjuntival needling, presenting an iris synechia on the goniopuncture that could be reduced conservatively. Long anterior zonule trait should be suspected in those patients presenting with a combination of narrow angle and pigment dispersion syndrome. The management of ocular hypertension and glaucoma associated to this trait is not protocolized. This communication discusses on the best action in this rare form of glaucoma.(AU)

ABSTRACT Introduction In April 2020 The COVID-19 pandemic caused more than one million infections and 54 600 deaths to date around the world. The spread of SARS-CoV-2 is rapid, and its transmission is through droplets of saliva, hence its importance in dentistry. Objective Identify the main risks, transmission routes and prevention measures against COVID-19. Methods A review of the scientific literature of the last two years on the subject was carried out in the PubMed, ScienceDirect, Google Scholar and Research Gate databases. The descriptors used were: "coronavirus", "COVID-19", "dental", "dentistry", "oral", "stomatology", and "aerosol". 350 articles were found, but 50 were selected for their topicality, relationship, and focus. The transmission of the COVID-19 is carried out mainly through saliva drops, aerosols and fomites. The virus can subsist for a time on the environment and surfaces. Dentists are health workers who are at risk of contagion because several of their procedures release aerosols. The biosecurity in the exercise of this profession must be strict and extreme, also the cleaning and disinfection of the environment and contact surfaces.

Are risky behaviors associated with tattoos? The association of tattooing with non-sexual health risk behaviors among Filipino college students / The Health Sciences Journal

INTRODUCTION@#The study aimed to determine the association of body tattooing and health risk behaviors among young adult Filipinos in a university in Metro Manila, as previous studies have linked tattooing to health risk behaviors such as alcoholism, violence, suicidality, illegal drug use and smoking.@*METHODS@#A convenience sample of students enrolled in randomly selected colleges from a university were recruited for the study. Researchers administered the Youth Risk Behavior Survey to the participants. Prevalence rate ratios were computed, and chi-square was utilized to test for significance and strength of association of the variables mentioned.@*RESULTS@#Among the risk behaviors studied, only smoking had a significant association with tattooing, with tattooed individuals being two times more likely to be engaged in smoking. Alcoholism, violence, suicidality and illegal drug use did not show significant associations with tattooing. @*CONCLUSION@#The presence of body tattoos was associated with increased engagement in smoking behaviors, though the association between tattooing and other risk behaviors should be further explored.

Jupiter's atmospheric jet streams extend thousands of kilometres deep.

The depth to which Jupiter's observed east-west jet streams extend has been a long-standing question. Resolving this puzzle has been a primary goal for the Juno spacecraft, which has been in orbit around the gas giant since July 2016. Juno's gravitational measurements have revealed that Jupiter's gravitational field is north-south asymmetric, which is a signature of the planet's atmospheric and interior flows. Here we report that the measured odd gravitational harmonics J3, J5, J7 and J9 indicate that the observed jet streams, as they appear at the cloud level, extend down to depths of thousands of kilometres beneath the cloud level, probably to the region of magnetic dissipation at a depth of about 3,000 kilometres. By inverting the measured gravity values into a wind field, we calculate the most likely vertical profile of the deep atmospheric and interior flow, and the latitudinal dependence of its depth. Furthermore, the even gravity harmonics J8 and J10 resulting from this flow profile also match the measurements, when taking into account the contribution of the interior structure. These results indicate that the mass of the dynamical atmosphere is about one per cent of Jupiter's total mass.

A suppression of differential rotation in Jupiter's deep interior.

Jupiter's atmosphere is rotating differentially, with zones and belts rotating at speeds that differ by up to 100 metres per second. Whether this is also true of the gas giant's interior has been unknown, limiting our ability to probe the structure and composition of the planet. The discovery by the Juno spacecraft that Jupiter's gravity field is north-south asymmetric and the determination of its non-zero odd gravitational harmonics J3, J5, J7 and J9 demonstrates that the observed zonal cloud flow must persist to a depth of about 3,000 kilometres from the cloud tops. Here we report an analysis of Jupiter's even gravitational harmonics J4, J6, J8 and J10 as observed by Juno and compared to the predictions of interior models. We find that the deep interior of the planet rotates nearly as a rigid body, with differential rotation decreasing by at least an order of magnitude compared to the atmosphere. Moreover, we find that the atmospheric zonal flow extends to more than 2,000 kilometres and to less than 3,500 kilometres, making it fully consistent with the constraints obtained independently from the odd gravitational harmonics. This depth corresponds to the point at which the electric conductivity becomes large and magnetic drag should suppress differential rotation. Given that electric conductivity is dependent on planetary mass, we expect the outer, differentially rotating region to be at least three times deeper in Saturn and to be shallower in massive giant planets and brown dwarfs.

Measurement of Jupiter's asymmetric gravity field.

The gravity harmonics of a fluid, rotating planet can be decomposed into static components arising from solid-body rotation and dynamic components arising from flows. In the absence of internal dynamics, the gravity field is axially and hemispherically symmetric and is dominated by even zonal gravity harmonics J2n that are approximately proportional to qn, where q is the ratio between centrifugal acceleration and gravity at the planet's equator. Any asymmetry in the gravity field is attributed to differential rotation and deep atmospheric flows. The odd harmonics, J3, J5, J7, J9 and higher, are a measure of the depth of the winds in the different zones of the atmosphere. Here we report measurements of Jupiter's gravity harmonics (both even and odd) through precise Doppler tracking of the Juno spacecraft in its polar orbit around Jupiter. We find a north-south asymmetry, which is a signature of atmospheric and interior flows. Analysis of the harmonics, described in two accompanying papers, provides the vertical profile of the winds and precise constraints for the depth of Jupiter's dynamical atmosphere.

Jupiter's interior and deep atmosphere: The initial pole-to-pole passes with the Juno spacecraft.

On 27 August 2016, the Juno spacecraft acquired science observations of Jupiter, passing less than 5000 kilometers above the equatorial cloud tops. Images of Jupiter's poles show a chaotic scene, unlike Saturn's poles. Microwave sounding reveals weather features at pressures deeper than 100 bars, dominated by an ammonia-rich, narrow low-latitude plume resembling a deeper, wider version of Earth's Hadley cell. Near-infrared mapping reveals the relative humidity within prominent downwelling regions. Juno's measured gravity field differs substantially from the last available estimate and is one order of magnitude more precise. This has implications for the distribution of heavy elements in the interior, including the existence and mass of Jupiter's core. The observed magnetic field exhibits smaller spatial variations than expected, indicative of a rich harmonic content.

Síndrome de iris flácido intraoperatorio tras tratamiento con duloxetina: ¿casualidad, asociación o causalidad? / Intraoperative floppy iris syndrome after treatment with duloxetine: coincidence, association, or causality?

CASO CLÍNICO: Se presenta un caso de síndrome de iris flácido intraoperatorio (IFIS) severo en una paciente que había recibido tratamiento con duloxetina. DISCUSIÓN: Aunque el agente etiológico principal es la tamsulosina, se han descrito casos de IFIS supuestamente secundarios a fármacos pertenecientes a diversos grupos farmacológicos. Los autores utilizan este caso para realizar un análisis crítico de todas estas asociaciones anecdóticas comunicadas en la literatura

CASE REPORT: The case is presented of a severe Intraoperative Floppy Iris Syndrome (IFIS) in a patient that had been treated with duloxetine. DISCUSSION: Tamsulosin is the main etiological agent involved in IFIS. However several cases of IFIS, supposedly secondary to drugs of different groups have recently been reported in the literature. The authors use this case report as a means to discuss why most of these cases should be considered anecdotal evidence

Irradiation of poly(tetrafluoroethylene) surfaces by CF4 plasma to achieve robust superhydrophobic and enhanced oleophilic properties for biological applications.

Poly(tetrafluoroethylene) (PTFE) was irradiated by CF4 plasma produced in the gas discharge ion source facility to produce stable and robust superhydrophobic surfaces and to enhance the materials' oleophilic property for biological applications. The characterizations employed on the samples are contact angle measurements, analysis of the surface morphology (scanning electron microscopy), surface roughness measurements (atomic force microscopy) and analysis of the surface chemistry (Fourier transform infrared spectroscopy). Superhydrophobic behavior with water contact angles as high as 156° was observed. The wettability of all the treated samples was found to be stable in time as evidenced by the statistically insignificant differences in the hysteresis contact angles. The level of enhanced hydrophobicity depended on the plasma energies (i.e. irradiation times, discharge current, and discharge voltage); higher plasma energies produced surfaces with high hydrophobicity. The plasma treatment also enhanced the oleophilic property of the materials' surface as evidenced by the decrease in the PDMS-oil contact angle from 33° to as low as 10°. The superhydrophobicity of the modified PTFE and the enhancement of its oleophilic property were due to (1) the changes in the roughness of the surface, (2) the formation of nanoparticles or nanostructures on the surface, and (3) the changes in the surface chemistry.

Biossegurança e resíduos de serviços de saúde no cotidiano acadêmico / Biosafety and health service waste in academic daily life

In this paper, the extent of the knowledge of the academic community on campus III of the Federal University of Paraná about biosafety and health service waste (HSW) is assessed. A survey was carried out between 2009 and 2011, among students of degree courses in Dentistry, Nutrition, Pharmacy, Occupational Therapy and Nursing, in their second, fifth, sixth, fourth and sixth semester, respectively, the course coordinators, campus environmental managers and waste handlers of the company contracted by UFPR. The method employed was participatory, based on the application of an assessment tool specific to each group surveyed. The results were that between 75 and 100% of the students recognized HSW as a risk to health and the environment when it is managed in adequately, but only 50 to 60% identified different types of health servicewaste. According to the course coordinators, only in Dentistry was Biosafety a taught subject. In other courses, the topics Biosafety and HSW were covered in other subjects. The environmental management sector managers reported that every waste-generating unit must have its own management plan, conduct training and possess an informative website. Regarding waste handlers, 33% said that during the handling of HSW they used gloves and uniforms, while 22% did not know what the rules said. The research revealed a gap in both the knowledge and practice of biosafe and responsible measures...

Intraoperative floppy-iris syndrome.

OBJECTIVE: Intraoperative-floppy iris syndrome (IFIS) has been recently described. It has been demonstrated that this new syndrome complicates cataract surgery. In this paper we have reviewed the syndrome, and offer practical information specially related to the origin and management of this syndrome and we offer practical information. MATERIAL AND METHODS: A review of the related medical literature using PubMed and Cochrane databases. Combining the search terms tamsulosin, cataract, IFIS and intraoperative floppy iris syndrome, more than 200 articles were found. Eighty-two of them were obtained and analysed. In the remaining only the abstract could be studied. RESULTS: The aetiological association between IFIS and tamsulosin (and to a lesser degree between IFIS and other alpha-antagonists) is well established. Other aetiological associations are doubtful. Most of the literature is centred on cataract surgery. However, a similar syndrome has been described during trabeculectomy. A possible association between these drugs and choroidal detachments has also been described. Undoubtedly tamsulosin treatment makes cataract surgery more difficult and increases the probability of intraoperative complications. Protocols to manage the syndrome have not yet been developed. Intracameral injection of alpha-adrenergic agonists seems to be useful. However there is no evidence of the usefulness of discontinuing the drug or using preoperative mydriatics. CONCLUSION: The aetiological and clinic features of the syndrome are well established. More studies are needed to provide scientific evidence on the most appropriate way to cope with this syndrome.

Síndrome del iris flácido intraoperatorio / Intraoperative floppy-iris syndrome

Objetivos: Recientemente se ha descrito el síndrome del iris flácido intraoperatorio (IFIS). Este síndrome complica la cirugía de catarata. Con este trabajo pretendemos revisar el síndrome, y ofrecer información práctica, especialmente en relación con los aspectos etiológicos y terapéuticos del mismo. Material y métodos: Revisión de la literatura biomédica relacionada, utilizando las bases de datos PubMed y Cochrane. Combinando los términos tamsulosin, cataract, IFIS e intraoperative floppy iris syndrome se identifican más de 200 artículos. Ochenta y 2 pudieron ser localizados y estudiados. En los restantes se estudió el resumen. Resultados: La asociación etiológica con la tamsulosina, y en menor medida con los restantes antagonistas de los receptores alfa, está bien establecida. Otras posibles asociaciones etiológicas son más dudosas. Aunque la mayor parte de los artículos se centran en la cirugía de catarata, también se ha documentado la aparición de un síndrome similar durante trabeculectomía, y se ha descrito la asociación de los antagonistas alfa con desprendimientos coroideos. El consumo de tamsulosina hace más difícil la cirugía de catarata y aumenta la probabilidad de que se produzcan complicaciones. La forma más adecuada de manejar el síndrome no está protocolizada. La inyección intracamerular de un agonista alfa adrenérgico mejora el comportamiento del iris. No existe evidencia científica de que suspender el fármaco o el uso de midriáticos preoperatorios resulte útil. Conclusiones: Los aspectos etiológicos y clínicos del síndrome están bien establecidos. Se precisan estudios que aporten evidencia científica sobre la forma más adecuada de manejar este síndrome(AU)

Anisocoria cotidiana: epidemiología de la anisocoria en un centro de nivel secundario / Everyday anisocoria: anisocoria epidemiology in a secondary care setting

Objetivo: Determinar la importancia relativa de las distintas formas de anisocoria en un centro sanitario de nivel secundario. Métodos: Estudio prospectivo longitudinal, incluyendo todos los pacientes remitidos por este motivo a la consulta de Neuroftalmología del Hospital Universitario del Henares, Madrid, España, desde noviembre de 2008 hasta octubre de 2011. Se estudiaron las diferencias en el diámetro pupilar en condiciones de alta y baja luminosidad. Los pacientes fueron sometidos a una exploración oftalmológica completa, y a las pruebas de apraclonidina, cocaína, pilocarpina 0,125% y pilocarpina 2% en caso de considerarse necesario. Resultados: Treinta y dos casos de anisocoria fueron referidos durante estos 3 años. No se encontró asociación con la edad ni el sexo. Los diagnósticos fueron: pupila de Adie, 4 casos; síndrome de Horner, 5 casos; midriasis unilateral episódica benigna, 3 casos; causas locales, 4 casos; anisocoria fisiológica, 5 casos. A pesar de una completa historia clínica y exploración, la causa de la anisocoria no se pudo determinar en 11 casos. En 4 de estos casos el paciente padecía migrañas y en otros 4 consumía psicofármacos. En 3 casos ambos factores de riesgo estaban presentes. En un caso la anisocoria fue la pista inicial que llevó al diagnóstico de un paraganglioma cervical. Conclusiones: La anisocoria es un signo clínico que no traduce habitualmente enfermedad grave. Con nuestros protocolos, un número alto de los casos de anisocoria queda sin filiar. La migraña y los psicofármacos podrían estar asociados a estas formas de anisocoria(AU)

Objetive: To determine the relative importance of the different forms of anisocoria in a General Hospital. Methods: A prospective, longitudinal study was conducted including all patients referred for this reason to the Neuro-Ophthalmology Unit of the Henares University Hospital, Madrid (Spain), from November 2008 to October 2011. The differences in pupil diameter were studied under high and low luminosity. The patients were given a full ophthalmological examination, as well as performing the apraclonidine, cocaine, pilocarpine 0.125% and pilocarpine 2% tests, if they were considered necessary. Results: Thirty-two cases of anisocoria were referred during the three years of the study. No relationship was found with age or gender. The diagnostic results were: Adie's pupil, 4 cases; Horner syndrome, 5 cases; benign episodic unilateral mydriasis, 3 cases; local causes, 4 cases; physiological anisocoria, 5 cases. Despite a full clinical history and examination, the cause of the anisocoria could not be determined in 11 cases. In 4 of these cases, the patient suffered from migraines and in another 4 psychotropic drugs were taken. Both risk factors were present in 3 cases. In one case the anisocoria was the initial clue that led to the diagnosis of a cervical paraganglioma. Conclusions: Anisocoria is a clinical sign that does not usually signify a serious disease. With our protocols, a high number of anisocoria cases are still of unknown origin. Migraines and psychotropic drugs could be linked to these forms of anisocoria(AU)
