El pediatra de Atención Primaria y la laringitis aguda / Primary care pediatrician and acute laryngitis

La laringitis aguda (crup) es una enfermedad común de origen viral, que constituye la causa más frecuente de obstrucción de la vía aérea superior en la infancia. Se caracteriza por la presencia de un grado variable de tos perruna o metálica, afonía, estridor y dificultad respiratoria. La incidencia estimada es del 3-6% de niños entre 3-6 meses y 6 años, con un pico máximo en el segundo año de vida y durante el otoño y el invierno. La principal causa es el virus parainfluenza tipo 1. El diagnóstico se realiza por la clínica, tos perruna, afonía y estridor inspiratorio. No son necesarias otras exploraciones. En función de la gravedad, que estableceremos con un score clínico, pautaremos el tratamiento. El tratamiento farmacológico será a base de corticoides y adrenalina en las laringitis moderadas y graves. La dexametasona oral es el corticoide de elección en todos los casos. (AU)

Acute laryngitis/croup is a common disease of viral origin, which is the most frequent cause of upper airway obstruction in childhood. It is characterized by the presence of a variable degree of dog or metal cough, aphonia, stridor and respiratory distress. The estimated incidence is 3-6% of children between 3-6 months and 6 years, with a peak in the second year of life and during the autumn and winter. The main cause is the parainfluenza virus type 1. The diagnosis is made based on the symptoms, barking cough, hoarseness and inspiratory stridor. No other examinations are necessary. Depending on the severity, which will be objectively established with a clinical score, will the treatment be prescribed. Oral corticosteroids are the treatment of choice in all diagnosed children. Pharmacological treatment is corticosteroids and adrenaline in moderate and severe laryngitis. Oral dexamethasone is the corticosteroid of choice in all cases. (AU)

Mutación en 665G intrón 2 Y V281L+360 insT del gen CYP21A2 como causa de Hiperplasia Suprarrenal Congénita

Introducción: La hiperplasia suprarrenal congénita se caracteriza por la alteración en la biosíntesis de los corticoides suprarrenales, conllevando presentaciones clínicas variables que van desde formas leves hasta formas potencialmente mortales. Es la enfermedad endocrinológica más común, tiene una incidencia de 1/10.000 casos por año, el abordaje diagnóstico incluye cariotipo, electrolitos, niveles de 17-hidroxiprogesterona, testosterona, progesterona, ecografía pélvica en niñas y la confirmación se realiza con estudio molecular, el tratamiento se basa principalmente en la suplencia hormonal deficiente. Caso clínico: Paciente masculino con antecedente de hospitalización en su etapa neonatal por cuadro de deshidratación, fallo en el medro, hiponatremia, hiperkalemia y macropene, reporte de 17-OH progesterona de más de 2000 ng /dl considerándose hiperplasia suprarrenal congénita, iniciando tratamiento con hidrocortisona y fludrocortisona. Ingreso a los 8 años 6 meses con acné, acantosis nigricans, testículos aumentados de tamaño, macropene y edad ósea adelantada, se hizo la confirmación con estudio molecular que reportó variantes en 655G del intrón 2 (variante que afecta el procesamiento del RNA mensajero) en su alelo materno, y la doble mutación Val281Leu+360 insT (variante de inserción que produce un desplazamiento de la fase de lectura) localizada en el exón 7, en su alelo paterno. Conclusión: a pesar de que es una enfermedad de baja frecuencia puede generar una gran morbimortalidad en cualquier etapa de la vida por eso la importancia de tener sensibilidad sobre la enfermedad para sospecharla y así mejorar la calidad y pronóstico de los pacientes que la padecen.

Introduction: Congenital adrenal hyperplasia is characterized by altered adrenal corticosteroid biosynthesis, leading to variable clinical presentations ranging from mild to life-threatening forms. It is the most common endocrinological disease, with an incidence of 1/10,000 cases per year, the diagnostic approach includes karyotype, electrolytes, levels of 17-hydroxyprogesterone, testosterone, progesterone, pelvic ultrasound in girls and confirmation is performed with molecular study, treatment is based mainly on deficient hormone replacement. Clinical case: Male patient with a history of hospitalization in his neonatal stage due to dehydration, failure in the medro, hyponatremia, hyperkalemia and macropenis, report of 17-OH progesterone of more than 2000 ng / dl being considered congenital adrenal hyperplasia, initiating treatment with hydrocortisone and fludrocortisone. Admission at 8 years 6 months with acne, acanthosis nigricans, enlarged testicles, macropenis and advanced bone age, confirmation was made with molecular study that reported variants in 655G of intron 2 (variant that affects the processing of messenger RNA) in his maternal allele, and the double mutation Val281Leu+360 insT (insertion variant that produces a displacement of the reading phase) located in exon 7, in his paternal allele. Conclusion: although it is a low frequency disease, it can generate a great morbimortality at any stage of life, that is why it is important to be aware of the disease in order to suspect it and thus improve the quality and prognosis of the patients who suffer from it.

[Cushing's syndrome with inhaled corticosteroid: Drug interactions to avoid]. / Syndrome de Cushing sous fluticasone inhalée : interactions médicamenteuses à éviter.

Cushing's syndrome is an iatrogenic event occurring during co-administration of inhaled corticosteroids and potent inhibitors of P450 cytochromes. We report the clinical case of a 29-year-old woman with a past history of asthma treated with inhaled fluticasone propionate (FP), chronic pulmonary aspergillosis and allergic bronchopulmonary aspergillosis (ABPA) treated with itraconazole (ITZ), and Mycobacterium xenopi infection treated with moxifloxacin (MXF), ethambutol (EMB) and clarithromycin (CLR). Four months after initiation of antibiotic and antifungal medication, the patient contracted Cushing's syndrome. Its etiology consisted in interaction between FP, ITZ and CLR, which led to pronouncedly increased corticosteroid concentrations in circulating plasma cells. Following on the one hand cessation of FP and ITZ and on the other hand hydrocortisone supplementation, evolution was favorable. Several cases of iatrogenic Cushing's syndrome induced by co-administration of FP and potent CYP3A4 inhibitors have been reported in the literature. If possible, FP should be avoided in patients being treated with CYP3A4 inhibitors. Due to its differing physicochemical properties, beclometasone may be considered as the safest therapeutic alternative.

[Communicating about the flare-up and its treatment]. / Bien communiquer sur la poussée et ses traitements.

Relapsing-remitting multiple sclerosis progresses by relapse. It is therefore necessary to know how to identify this phenomenon in order to be able to provide the best possible support to patients. The term "relapse" is used to characterize the period of a few days to a few weeks during which an attack of inflammation of the myelin occurs. Depending on the area affected, the symptoms will be different. To qualify as a relapse, the patient must have had new, permanent symptoms for at least 24 hours without fever or signs of infection and within 30 days of the last relapse.

[Comparison of available clinical and imaging tools to assess good positioning of a fluocinolone acetonide implant (Iluvien®) in the vitreous cavity after injection]. / Comparaison des moyens clinique et d'imagerie disponibles en pratique clinique pour objectiver la présence de l'implant d'acétonide de fluocinolone (Iluvien®) dans la cavité vitréenne après injection.

INTRODUCTION: Sustained-release corticosteroid implants are injected into the vitreous cavity using preloaded pens. The fluocinolone (FAc) implant is approximately half the size of the dexamethasone implant (Dex-I). It is simply introduced in the vitreous base rather than propelled into the vitreous cavity as is Dex-I. Verification of its positioning after injection is thus difficult by indirect ophthalmoscopy. The goal of our study is to compare the performance of available clinical and imaging tools to confirm the presence of the FAc in the vitreous cavity following injection. METHODS: Twelve eyes of 12 consecutive patients were included in a retrospective, single-center, observational study carried out at the Bordeaux University Hospital, France. All patients were injected with the FAc after pupil dilation, and presence of the implant was immediately checked by indirect biomicroscopy, wide-field retinography (Clarus®, Carl-Zeiss-Meditec, Dublin, CA, USA) and ultra-wide-field retinography (California®, Optos, Edinburgh, United-Kingdom). Seven days later, a B-mode ultrasonography (10MHz, AVISO, Quantel-medical, France) and an UBM ultrasonography (50MHz, AVISO, Quantel-medical, France) were performed. RESULTS: Indirect biomicroscopy and wide-field retinography detected 4/12 implants (33.3%). Ultra-wide-field retinophotography detected 6/12 implants (50%). All the implants seen using indirect biomicroscopy and wide-field retinography were also visualized with ultra-wide-field. B-mode ultrasonography showed 5/12 implants (41.6%) and UBM 9/12 implants (75%). Finally, one implant dislocated into the anterior chamber and was seen in the iridocorneal angle on gonioscopy. CONCLUSION: Objective confirmation of the proper positioning of the FAc implant in the vitreous cavity is mandatory. If both indirect ophthalmoscopy and anterior examination fail to detect it, ultra-wide field retinography along with UBM ultrasonography, if necessary, appear to be the two best imaging modalities to use.

Abordaje multidisciplinarde un paciente con una úlceraperianal asociada a pomadaantihemorroidal / Multidisciplinary approach to a patient with a perianal ulcer associated with hemorrhoidal ointment

Introducción: Hasta la fecha, la manifestación de una úlcera perianalprovocada por una pomada antihemorroidal no se ha descrito confrecuencia. Sin embargo, se ha objetivado un incremento de loscasos durante la pandemia de COVID-19. Caso clínico: Varónde 82 años independiente, que presentó una úlcera perianal de35,8 cm² sin ninguna patología ni enfermedad concomitante queexplicara su causa. La aplicación de criterios de exclusión exhaustivos,incluida una biopsia para rechazar el pioderma gangrenoso,identificó una pomada rectal hemorroidal como la causa de la úlcera.Plan de actuación: La herida curó tras aplicar una intervenciónmultidisciplinaria y una terapia con factores de crecimientoautólogos. Discusión y conclusiones: Este caso ha sido escasamentereportado en la literatura, aunque esta pomada hemorroidal secomercializa desde hace más de 40 años.

Introduction: Perianal ulcers resulting from the use of hemorrhoidalointments have been rarely reported to date. Nevertheless, therehas been a surge in the number of cases reported during theCOVID-19 pandemic. Case report: An independent 82-year-oldmale experienced a 35,80 cm² perianal ulcer, with no underlyingcondition or concomitant disease that could explain the cause ofthe ulcer. The application of thorough exclusion criteria, including abiopsy to rule out pyoderma gangrenosum, led to the identificationof a hemorrhoidal rectal ointment as the cause. Action plan: Theulcer healed completely when a multidisciplinary intervention and anautologous growth factors advanced therapy were applied. Discussionand conclusions: This case has been scarcely reported in the literature,although this hemorrhoidal ointment has been on the market for over40 years. Medical assessment before prescription and patients’ followup is recommended. (AU)

Tuberculosis pericárdica de evolución inusual en paciente inmunocompetente / Unusual evolution pericardial tuberculosis in immunocompetent patient

La tuberculosis pericárdica es una manifestación poco frecuente de la tuberculosis extrapulmonar. Se presenta de manera insidiosa e inespecífica, lo que dificulta el diagnóstico, retrasa el tratamiento, y lleva a complicaciones graves, como el derrame pericárdico con signos de taponamiento cardíaco o pericarditis constrictiva. Se describe el caso de una paciente femenina de 18 años, embarazada, con antecedente de contacto estrecho con familiar con tuberculosis pulmonar, que consultó al servicio de urgencias por disnea. Entre los estudios solicitados, el ecocardiograma evidenció la presencia de un derrame pericárdico con compresión de cavidades, por lo que requirió pericardiocentesis. El cultivo del líquido pericárdico informó Mycobacterium tuberculosis y se inició trata miento antituberculosis y corticoides. Evolucionó con recurrencia del derrame a pesar de tratamiento médico adecuado y realización de ventana pericárdica.

Pericardial tuberculosis (TBP) is a rare manifestation of extrapulmonary tuberculosis (TB). It presents insidiously and nonspecifically, making diagnosis difficult and delaying treatment, leading to serious complications such as pericardial effusion with signs of cardiac tamponade or constrictive pericarditis. The case of an 18-year-old female patient, pregnant, with a history of close contact with a relative with pulmonary TB is described; she consulted the Emergency Service for dyspnea. Among the studies requested, the echocardiogram showed pericardial effusion with compression of cavities, requiring pericardiocentesis. Pericardial fluid culture revealed Mycobacterium tuberculosis and antituberculous treat ment plus corticosteroids were started. It evolved with a recurrence of effusion despite adequate medical treatment and the performance of a pericardial window.

Introduction and objective: Meniere ́s disease (MD) is a chronic auditory pathology charac-terized by the presence of hearing loss, episodic dizziness and tinnitus. The objective of this studie is to value the hearing improvement and the reduction of vertiginous crises in patients with Meniere ́s disease after the administration of intratympanic corticosteroids (ITS). Method: Retrospective cohort study of a sample of 55 patients diagnosed with definitive Meniere ́s disease and treated with intratympanic corticosteroids. Results: Of the 39 patients who were treated with ITS for vertigo attacks, one month into the treatment, 27 had no attacks, 11 experienced a few (<5) and only 1 had several attacks (5-10). Six months after the first injection, 19 had no seizures, 13 reported a few, 5 had several, and 2 manifested numerous attacks (> 10). There were 16 patients treated with ITS for hearing loss and they reflected a mean hearing loss of 46.61 dB prior to the treatment. One month after the injection, the mean loss was 42.77 dB (1.84) and at six months it was 41.66 dB (2.95). Discussion: The audiometric benefit obtained is ≈3 dB und a clear decrease in the number of vertiginous crises after ITS, other authors in their studies have obtained results similar to ours. Conclusions: Our results show that intratympanic corticosteroids is an effective therapy for the control of vertiginous crises and hearing loss. (AU)

Biomedicine on hormone mediation of sports in adolescent height development / Biomedicina na mediação hormonal do esporte para desenvolvimento da altura dos adolescentes / Biomedicina en la mediación hormonal del deporte para el desarrollo de la estatura de los adolescentes

ABSTRACT Introduction: Physical exercise is an important factor in regulating energy balance and body composition. Exercise itself is a kind of body stress. It involves the central nervous system, cardiovascular, respiratory, endocrine, and other systems. Sports have various effects on the hormones in adolescent height development. Objective: This article analyzes the effects of different time and load exercise training on the levels of serum testosterone, free testosterone, and cortisol in young athletes. Methods: The athletes' blood samples were collected at the quiet time in the morning before each experiment, immediately after exercise, and at three time intervals the next morning. Then blood testosterone (T), free testosterone (FT), and corticosteroids (C) were measured. Results: One-time and one-day high-volume training can cause a decrease in serum testosterone and free testosterone levels and an increase in cortisol hormones in young athletes. The testosterone level of young athletes rises immediately after exercise. Conclusion: Hormonal changes after physical exercise provide a scientific basis for athlete exercise load prediction and exercise plan formulation. Level of evidence II; Therapeutic studies - investigation of treatment results.

RESUMO Introdução: O exercício físico é um fator importante na regulação do equilíbrio energético e da composição corporal. O exercício em si é um tipo de estresse corporal.

Éxito del tratamiento conservador de la fimosis, ¿la pauta de aplicación de corticoide tópico influye? / Success of conservative treatment of phimosis, does the topical corticosteroid application regime influence this?

Introducción. Actualmente no existe una pauta de aplicación única establecida para el tratamiento tópico corticoideo de la fimosis. Nos planteamos comparar la efectividad de dos de las pautas más utilizadas, así como la importancia de otros factores en el éxito del tratamiento conservador. Material y métodos. Estudio analítico de tipo cohortes retrospectivas, incluyendo niños con fimosis no complicada a los que se instauró dos pautas distintas de aplicación de corticoide tópico (con periodo de descanso y con dosis descendente). Se estudió el resultado final circuncisión o curación en base a la pauta y a otros factores epidemiológicos. Resultados. Se incluyeron 159 niños con edad media de 6 años. La pauta con descanso se aplicó en el 57,9% de los pacientes con una adherencia del 93,4% y una tasa de curación del 83,7%, frente al 79,1% de grupo con pauta descendente (diferencia no significativa). Se observó un mayor riesgo de circuncisión en pacientes con tratamiento tópico previo y con prepucio cicatricial y un papel protector de la adherencia al tratamiento. La presencia de balanitis previa o el grado de fimosis no se asocian con mayor fracaso del tratamiento. Conclusiones. Las pautas de aplicación estudiadas no presentan diferencias significativas en la tasa de curación. No obstante, la adherencia es mayor con la pauta con descanso por lo que parece recomendable. Las balanitis y el grado alto de fimosis no serían contraindicación inicial del tratamiento conservador (AU)

Introduction. Currently there is no single application guideline established for the topical corticosteroid treatment of phimosis. We set out to compare the effectiveness of two of the most widely used guidelines, as well as the importance of other factors in the success of conservative treatment. Material and methods. Retrospective cohort-type analytical study, including children with uncomplicated phimosis who received two different regimens of topical corticosteroid application (with a rest period and a descending dose). The final result of circumcision or cure was studied based on the guideline and other epidemiological factors. Results. 159 children with a mean age of 6 years were included. The regimen with rest was applied in 57.9% of the patients with an adherence of 93.4% and a cure rate of 83.7%, compared to 79.1% in the group with a descending regimen (non-significant difference). An increased risk of circumcision was observed in patients with previous topical treatment and with scarred foreskin and a protective role of adherence to treatment. The presence of previous balanitis or the degree of phimosis is not associated with greater treatment failure. Conclusions. The application guidelines studied do not show significant differences in the cure rate. However, adherence is greater with the rest pattern, so it seems advisable. Balanitis and a high degree of phimosis would not be an initial contraindication to conservative treatment (AU)

La surdité brusque résultats thérapeutique et facteurs pronostiques / Sudden sensorineural hearing loss: therapeutic outcome and prognostic factors

Objectifs: évaluer les résultats thérapeutiques et étudier les facteurs pronostiques de la surdité brusque.Patients et méthodes: Il s'agit d'une étude rétrospective à propos de 61 patients (39 hommes et 22 femmes) pris en charge pour surdité brusque dans le service d'Otorhinolaryngologie et de Chirurgie Cervico-Faciale de l'hôpital Bourguiba de Monastir durant une période de 16 ans (2001-2016). Une analyse statistique a été réalisée afin d'identifier les facteurs influençant le pronostic de la surdité brusque. Le seuil de significativité retenu était de 5%. Résultats:L'âge moyen était de 43 ans [16-80 ans]. Le taux global de récupération auditive était de 45%. Les facteurs pronostiques selon l'analyse uni variée étaient: un antécédent d'hypoacousie controlatérale, la présence d'un vertige associé, la sévérité de la perte auditive initiale, une courbe audiométrique de type E, l'absence du réflexe stapédien et le recours à l'oxygénothérapie hyperbare (OHB). En analyse multivariée, les seuls facteurs retenus étaient une perte auditive initiale supérieure ou égale à 70 dB, la présence d'un vertige et l'absence d'un épisode infectieux précédant la survenue de la surdité. Conclusion: Notre étude a permis de retenir comme facteurs de mauvais pronostic indépendants la perte auditive initiale supérieure ou égale à 70 dB, la présence d'un vertige et l'absence d'un épisode infectieux précédant la survenue de la surdité. Ceci nous incite à une réflexion quant au protocole thérapeutique adopté dans notre service et à indiquer l'OHB, qui est normalement prescrite en cas de non réponse, en première intention, afin d'optimiser la récupération auditive.

Múltiples úlceras perianales en relación con el uso de una pomada antihemorroidal con acetónido de triamcinolona, lidocaína y pentosano polisulfato sódico como principios activos: una serie de 11 pacientes españoles / Multiple Perianal Ulcers Related to Use of a Hemorrhoidal Ointment With the Active Ingredients Triamcinolone Acetonide, Lidocaine, and Pentosan Polysulfate Sodium: A Series of 11 Spanish Patients

La aparición de úlceras perianales en relación con una pomada antihemorroidal es una condición nunca antes reportada en la literatura. Presentamos una serie de 11 casos de 10 hospitales españoles con diagnóstico de úlceras perianales tras la aplicación de una misma pomada antihemorroidal con acetónido de triamcinolona, lidocaína y pentosano polisulfato sódico como principios activos. No se ha podido identificar ninguna condición previa o enfermedad concomitante que pudiera justificar un diagnóstico etiológico alternativo y tras retirar la pomada antihemorroidal se ha evidenciado una resolución completa de las úlceras en un periodo medio de 8 semanas. Esta serie de casos evidencia el potencial efecto dañino de un producto farmacéutico no sujeto a prescripción ni seguimiento médico y la necesidad de interrogar por el uso de agentes tópicos ante la aparición de úlceras perianales (AU)

The development of perianal ulcers related to the use of a hemorrhoidal ointment has not been reported in the literature. We describe a series of 11 patients who were treated for perianal ulcers in 10 Spanish hospitals after they used the same ointment containing the active ingredients triamcinolone acetonide, lidocaine, and pentosan polysulfate sodium. No prior or concomitant conditions suggesting an alternative cause for the condition could be identified, and after the patients stopped using the ointment, their ulcers cleared completely in 8 weeks on average. This case series shows the damage that can be caused by an over-the-counter pharmaceutical product used without medical follow-up. It also illustrates the need to ask patients with perianal ulcers about any topical agents used before the lesions appeared (AU)

Finally, it is concluded that there is a need for broader studies to help create systematic protocols for the diagnosis and approach of this condition.

Feline demodicosis in Santa Catarina state, Brazil / Demodicose felina em Santa Catarina, Brasil

Feline demodicosis is considered a rare dermatopathy and can be caused by Demodex cati, Demodex gatoi and a third species not yet named. An adult male feline was attended with severe pruritus for 9 months and a history of treatment with cephalexin and prednisolone, with progressive worsening. On physical examination, there was alopecia, hyperkeratosis, abrasions and erythema on the head, neck, lumbosacral region, tail and pelvic limbs, in addition to the presence of fleas. For pulicosis, selamectin spot on was prescribed every 30 days and use of amitraz in the environment every seven days. In order to control secondary infection, weekly baths with chlorhexidine were recommended. Deep skin scraping and hair plucking were performed for trichogram and parasitological skin examination, respectively, with diagnoses of demodicosis by Demodex cati, and mycotic dermatitis associated with secondary bacterial infection. The treatment was modified to use selamectin every 2 weeks, but the tutor did not return and reported, after several months, that he had done therapy with selamectin only every 30 days and discontinued baths. For this feline, it was not possible to associate demodicosis with other comorbidities. It is believed that the generalized presentation of the disease occurred due to the pruritus caused by pulicosis.

A demodicose felina é considerada uma dermatopatia rara e pode ser causada pelos ácaros Demodex cati,Demodex gatoi e uma terceira espécie ainda não nomeada. Foi atendido um felino adulto apresentando prurido intenso há 9 meses e histórico de tratamento com cefalexina e prednisolona, com piora progressiva. Ao exame físico, havia alopecia, hiperqueratose, escoriações e eritema em cabeça, pescoço, região lombossacra, cauda e membros pélvicos, além da presença de pulgas. Para puliciose, foram prescritos selamectina spot on a cada 30 dias e uso de amitraz no ambiente a cada sete dias e, para controle da infecção secundária pelas escoriações, foram recomendados banhos semanais com clorexidine. Realizaram-se raspado de pele profundo e arrancamento de pelos para tricograma e exame parasitológico de pele, respectivamente, com diagnósticos de demodicose por Demodex cati, e dermatite micótica associada a infecção bacteriana secundária. O tratamento foi modificado para uso de selamectina a cada 2 semanas, mas tutor não retornou e informou, após vários meses, ter feito terapia com selamectina apenas a cada 30 dias e descontinuidade dos banhos. Não foi possível associar a demodicose, para este felino, a outras comorbidades e acredita-se que a apresentação generalizada da doença tenha se dado pelo prurido causado pela puliciose.

Feline demodicosis is considered a rare dermatopathy and can be caused by Demodex cati, Demodex gatoi and a third species not yet named. An adult male feline was attended with severe pruritus for 9 months and a history of treatment with cephalexin and prednisolone, with progressive worsening. On physical examination, there was alopecia, hyperkeratosis, abrasions and erythema on the head, neck, lumbosacral region, tail and pelvic limbs, in addition to the presence of fleas. For pulicosis, selamectin spot on was prescribed every 30 days and use of amitraz in the environment every seven days. In order to control secondary infection, weekly baths with chlorhexidine were recommended. Deep skin scraping and hair plucking were performed for trichogram and parasitological skin examination, respectively, with diagnoses of demodicosis by Demodex cati, and mycotic dermatitis associated with secondary bacterial infection. The treatment was modified to use selamectin every 2 weeks, but the tutor did not return and reported, after several months, that he had done therapy with selamectin only every 30 days and discontinued baths. For this feline, it was not possible to associate demodicosis with other comorbidities. It is believed that the generalized presentation of the disease occurred due to the pruritus caused by pulicosis.

Effect of different doses of dexamethasone on labor in Santa Inês ewes and its influence on the onset of labor and the expulsion of fetal membranes / Efeito de diferentes doses de dexametasona para a indução do parto em ovelhas Santa Inês e sua influência sobre as características do parto

The induction of labor aims to concentrate births to follow up better the parturient and the first care to the neonates. However, even if the labor induction technique with dexamethasone administration has been successfully described since the late 1970s, few studies report the technique of birth development and neonatal vitality in Santa Inês sheep. This study aimed to evaluate the efficiency of dexamethasone use in two doses (8 and 16mg) in labor induction of Santa Inês ewes at 145 days of gestation and to evaluate its effects on the birth characteristics. In this study, 58 ewes were used, raised in an extensive system in the experimental farms of UFBA, with confirmation pregnancy after fixed-time artificial insemination or controlled breeding. These female ewes were separated into three groups according to the dose of dexamethasone administered (G1 = 0mg, G2 = 8mg, and G3 = 16mg). From these births, 79 lambs were born. This study analyzed the period from induction of labor to birth, fetal presentation at birth, the weight of the placenta, and the period for placenta expulsion. The data were analyzed by the Statistical Analysis System (SAS v.9.1.3®, 2002), and the significance level considered for all analyzes was 5%. Births of induced groups occurred on average at 48.4±22.17 hours after induction, while the females with non-induced labor gave birth 131.96±41.9 hours on average after the placebo application (P<0.05), confirming the efficiency of both doses for induction of labor. The period from induction to birth did not differ (P>0.05) between the doses used. There were no differences in delivery about the fetal static relation, time to placental attachment, and weight. With this study, it can be concluded that the induction at 145 days of gestation with eight or 16mg of dexamethasone is a useful technique and does not alter the labor in Santa Inês sheep.(AU)

A indução do parto visa concentrar os nascimentos para melhor acompanhamento das parturientes e primeiros cuidados aos neonatos. Contudo, mesmo que a técnica de indução de parto, com administração de dexametasona, tenha sido descrita com sucesso desde o final da década de 70, existem estudos escassos que relatam a influência desta técnica sobre o parto em ovinos da raça Santa Inês. Dessa forma, o objetivo do estudo foi avaliar a eficácia da dexametasona em duas doses (8 e 16mg), para a indução do parto de ovelhas Santa Inês com 145 dias de gestação e avaliar os seus efeitos nas características de desencadeamento e finalização do parto. Para este estudo foram utilizadas 58 ovelhas, criadas em sistema extensivo nas fazendas experimentais da UFBA, com prenhez confirmada após inseminação artificial em tempo fixo ou monta controlada. Essas fêmeas foram separadas em três grupos, de acordo com a dose de dexametasona administrada (G1 = 0mg, G2 = 8mg e G3 = 16mg). Destes partos nasceram 79 cordeiros. Foram avaliados o período em horas da indução do parto aos nascimentos, a apresentação fetal ao nascimento, assim como o peso da placenta e o período para o delivramento. Os dados foram analisados pelo pacote estatístico Statistical Analysis System (SAS v.9.0®, 2002) sendo considerado para todas as análises o nível de significância de 5%. Os nascimentos dos grupos induzidos ocorreram em média com 48,4±22,1 horas após a indução, enquanto que as fêmeas com parto não induzido pariram em média 131,96±41,9 horas após aplicação do placebo (P<0,05), confirmando a eficácia de ambas as doses para indução do parto. O período da indução até o parto não diferiu (P>0,05) entre as doses utilizadas. Não ocorreram diferenças no parto em relação à estática fetal, tempo para o delivramento e peso da placenta nos diferentes grupos. Com este estudo, conclui-se que a indução de parto em ovelhas aos 145 dias de gestação com oito e 16 mg de dexametasona é uma técnica eficaz e que não altera o trabalho de parto nas ovelhas da raça Santa Inês.(AU)

Ocular hypertension as a cause of cilioretinal artery obstruction in the young patient, about a case. / Hipertensión ocular como causa de obstrucción de arteria ciliorretiniana en el paciente joven, a propósito de un caso.

CLINICAL CASE: A 16-year-old patient seen in the Emergency Department due to loss of visual acuity (VA) in the left eye (LE), and oppressive headache of 1 day onset. The patient was on treatment with topical corticosteroids for viral conjunctivitis. The VA was 1.00 in the right eye and 0.05 in LE. The intraocular pressure was 42mmHg in both eyes. In the LE, the funduscopy revealed retinal ischaemic oedema in the papillomacular bundle. The optical coherence tomography angiography (OCT-A) showed an obstruction of the cilioretinal artery. The systemic study was normal, the cardiac and supra-aortic trunks ultrasound was normal, with ocular hypertension secondary to corticosteroids being the only causative agent identified. This case shows that in the event of an obstruction of the cilioretinal artery, a systemic study should be performed in order to identify possible embolic phenomena. Ocular hypertension is one of the possible causes that may be responsible for this condition.
