Trigeminal Neuralgia in COVID-19: A meta-analysis

The trigeminal nerve is the fifth cranial nerve, which transmits facial sensations, and is divided into the ophthalmic, maxillary, and mandibular branches. Damage to this nerve can cause trigeminal neuralgia, a clinical condition that can also present in patients with coronavirus disease 2019 (COVID-19). This meta-analysis reviews the clinical cases of trigeminal neuralgia reported in patients with COVID-19 from 2019 to 2022, describes the anatomical mechanism of pain and its radiation and identifies other associated symptoms. We performed a literature search to identify reports of patients with COVID-19 who developed trigeminal neuralgia and examined these cases for prevalence and any identified source of associated ocular pain. Of the relevant studies identified, 638 patients with COVID-19 developed trigeminal neuralgia out of 7561 total COVID-19 cases (8.4 %). Of the 638 cases, 590 (7.8 %) had known causes of ocular pain, while the cause of ocular pain was unknown in 48 cases (0.6 %). Trigeminal neuralgia developed infrequently in patients with COVID-19, and cases with known causes of ocular pain were more common than cases with unknown causes. Understanding the link between COVID-19 and trigeminal neuralgia may lead to preventing further complications and mortality in these patients, as well as improving care for patients with these conditions in the future. Additionally, understanding these new clinical issues can prepare many types of physicians to protect themselves better in the event of a COVID-19 outbreak among medical staff in different departments of hospitals, such as clinics, wards, emergency rooms, and operating theatres.

El nervio trigémino es el quinto par craneal, que transmite las sensaciones faciales, y se divide en las ramas oftálmica, maxilar y mandibular. El daño a este nervio puede causar neuralgia del trigémino, una condición clínica que también puede presentarse en pacientes con enfermedad por coronavirus 2019 (COVID-19). Este metaanálisis revisa los casos clínicos de neuralgia del trigémino informados en pacientes con COVID-19 desde 2019 hasta 2022, describe el mecanismo anatómico del dolor y su radiación e identifica otros síntomas asociados. Realizamos una búsqueda bibliográfica para identificar informes de pacientes con COVID-19 que desarrollaron neuralgia del trigémino y examinamos estos casos en busca de prevalencia y cualquier fuente identificada de dolor ocular asociado. De los estudios relevantes identificados, 638 pacientes con COVID-19 desarrollaron neuralgia del trigémino de un total de 7561 casos de COVID-19 (8,4 %). De los 638 casos, 590 (7,8 %) tenían causas conocidas de dolor ocular, mientras que la causa del dolor ocular era desconocida en 48 casos (0,6 %). La neuralgia del trigémino se desarrolló con poca frecuencia en pacientes con COVID-19, y los casos con causas conocidas de dolor ocular fueron más comunes que los casos con causas desconocidas. Comprender el vínculo entre COVID-19 y la neuralgia del trigémino puede ayudar a prevenir más complicaciones y mortalidad en estos pacientes, así como a mejorar la atención de los pacientes con estas afecciones en el futuro. Además, comprender estos nuevos problemas clínicos puede preparar a muchos tipos de médicos para protegerse mejor en caso de un brote de COVID-19 entre el personal médico en diferentes departamentos de hospitales, como clínicas, salas de emergencia y quirófanos.

Hallazgos de retinopatía diabética por ecografía Doppler arterial oftálmico en pacientes con diabetes mellitus tipo 2 / Findings of Diabetic Retinopathy by Ophthalmic Arterial Doppler Ultrasound in Patients with Type 2 Diabetes Mellitus

Objetivo: Determinar los hallazgos de retinopatía diabética por ecografía doppler arterial oftálmico en pacientes con diabetes mellitus tipo 2. Métodos: Se efectuó un estudio observacional descriptivo y transversal en 200 órbitas de 100 pacientes diabéticos, a los que se les realizó fondo de ojo para diagnóstico y gradación de la retinopatía diabética. Por interrogatorio y examen físico se determinó el tiempo de diagnóstico de la diabetes y la presencia o ausencia de obesidad. Además, se les hizo ultrasonido orbitario y Doppler carotídeo, y solo en caso de resultar normales, se procedió a evaluar mediante ecografía doppler a las arterias oftálmicas. Resultados: Predominaron los diabéticos entre 40 y 60 años, el sexo masculino, los casos sin retinopatía diabética, y el grupo de más de 10 años de diagnóstico de la diabetes. Se demostró una disminución de la velocidad del flujo y un incremento de la resistencia vascular a nivel de las arterias oftálmicas, en tanto se evidenció asociación significativa de estos parámetros hemodinámicos con el envejecimiento, la presencia o ausencia de obesidad, el tiempo de diagnóstico de la diabetes y la severidad de la retinopatía diabética. Sin embargo, no se encontró asociación significativa con el sexo. Conclusiones: La valoración mediante ecografía doppler de las arterias oftálmicas, haría más completo el estudio y seguimiento de los pacientes con diabetes mellitus tipo 2(AU)

Purpose: To determine the findings of diabetic retinopathy by ophthalmic arterial Doppler ultrasound in patients with type 2 diabetes mellitus. Methods: A descriptive and cross-sectional observational study was carried out in 200 orbits of 100 diabetic patients, who underwent fundus examination for diagnosis and grading of diabetic retinopathy. The time of diagnosis of diabetes and the presence or absence of obesity were determined by interrogation and physical examination. In addition, orbital ultrasound and carotid Doppler were performed, and only if they were normal, the ophthalmic arteries were evaluated by Doppler ultrasound. Results: Diabetic patients between 40 and 60 years of age, from the male gender, cases without diabetic retinopathy, and the group with more than 10 years of diagnosed diabetes predominated. A decrease in flow velocity and an increase in vascular resistance at the level of the ophthalmic arteries were demonstrated, while a significant association of these hemodynamic parameters with aging, presence or absence of obesity, time of diagnosis of diabetes and severity of diabetic retinopathy was evidenced. However, no significant association was found as to gender. Conclusions: Doppler ultrasound assessment of the ophthalmic arteries would make the study and follow-up of patients with type 2 diabetes mellitus more complete(AU)

Subbasal corneal nerve damage in patients with bacterial keratitis: in vivo confocal microscopy study / Danos no plexo nervoso subbasal corneano em pacientes com ceratite bacteriana utilizando a microscopia confocal in vivo

ABSTRACT Purpose: To examine subbasal corneal nerve changes in patients with bacterial infectious keratitis using in vivo confocal microscopy. Methods: Thirteen patients (13 eyes) with unilateral bacterial keratitis and 12 healthy controls were prospectively enrolled in the study. In vivo confocal microscopy was performed in all the patients at 2 time points, in the acute phase of infectious keratitis and at 28 ± 0.6 months after resolution of the infection. Results: The subbasal nerve length was 5.15 ± 1.03 mm/mm2 during the acute phase of bacterial keratitis (compared with that of the controls: 19.02 ± 1.78 mm/mm2, p<0.05). Despite the significant corneal nerve regeneration over the interval of 28 months after the resolution of the infection, the nerve density was still significantly reduced as compared with that of the controls (9.73 ± 0.93 mm/mm2, p<0.05). Moreover, in vivo confocal microscopy images showed diffuse high-reflecting areas referring to the scar tissue areas with thin and tortuous nerve branches regenerating toward these areas. Conclusions: A partial corneal nerve regeneration of subbasal nerve plexus during the first 28 months after the acute phase of infectious keratitis was observed. Moreover, the regenerated nerves of the patients remained morphologically altered as compared with those of the healthy controls. These results may be relevant to the clinical follow-up and surgical planning for these patients.

RESUMO Objetivo: Relatar as alterações no plexo nervoso corneano subbasal em pacientes com ceratite infecciosa de origem bacteriana utilizando a microscopia confocal in vivo. Métodos: Treze olhos de 13 pacientes com ceratite bacteriana unilateral e 12 indivíduos saudáveis como grupo controle foram incluídos prospectivamente no estudo. A microscopia confocal in vivo foi realizada em todos os pacientes em 2 momentos: na fase aguda da ceratite infecciosa e após 28 ± 0,6 meses da resolução da infecção. Resultados: A densidade dos nervos no plexo subbasal foi de 5,15 ± 1,03 mm/mm2 na fase aguda da ceratite infecciosa (comparada com o grupo controle: 19,02 ± 1,78 mm/mm2, p<0,05). Apesar de significativa regeneração dos nervos corneanos ao longo de um intervalo de 28 meses após a resolução da infecção, a densidade dos nervos se manteve significativamente reduzida (9,73 ± 0,93 mm/mm2) quando comparada com o grupo controle (19,02 ± 1,78 mm/mm2, p<0,05). Além disso, as imagens obtidas com a microscopia confocal mostraram áreas de hiperreflectividade referente ao tecido corneano cicatricial com ramos de nervos, afinados e tortuosos, se regenerando nessas áreas. Conclusões: Foi observado regeneração parcial dos nervos do plexo corneano subbasal durante os primeiro 28 meses após a resolução da fase aguda da ceratite infecciosa. Além disso, os nervos corneanos regenerados se mantiveram morfologicamente alterados quando comparados ao grupo controle. Esses resultados podem ser relevantes para o acompanhamento clínico e planejamento cirúrgico desses pacientes.

Glaucoma primario de ángulo abierto y factores de riesgo aterosclerótico: hallazgos por eco-Doppler orbitario / Primary open angle glaucoma and atherosclerotic risk factors: orbital echo-Doppler findings

Objetivo: Determinar los hallazgos por eco-Doppler orbitario en pacientes con glaucoma primario de ángulo abierto según factores de riesgo aterosclerótico. Métodos: Se realizó un estudio observacional descriptivo y transversal en 300 órbitas de 150 pacientes con diagnóstico de glaucoma primario de ángulo abierto. A todos los casos se les realizó tonometría de contorno dinámico y tomografía de coherencia óptica. Se identificaron mediante interrogatorio y por el laboratorio clínico los factores de riesgo aterosclerótico: hipertensión arterial, tabaquismo, diabetes mellitus tipo 2, dislipidemia, obesidad y consumo excesivo de alcohol. Se les realizó ultrasonido orbitario y Doppler carotídeo, y solo en caso de resultar normales se procedió a evaluar mediante eco-Doppler las arterias oftálmica, central de la retina y ciliares posteriores temporales. Resultados: La edad media de los sujetos estudiados fue de 62,3 años. El 55,3 por ciento correspondió al sexo femenino y el 47,3 por ciento al color blanco de la piel. El número de factores de riesgo mostró una correlación lineal moderada, positiva y significativa con el índice de resistencia, mientras que con las velocidades dicha correlación resultó ser negativa. Todos los factores de riesgo expresaron efectos dañinos sobre la hemodinámica del flujo ocular, la presión intraocular y el grosor de las capas de fibras neurorretinianas temporales. Tras ajustar para la edad, esta negativa influencia continuó siendo relevante en la mayoría de los casos. Conclusiones: Los aspectos vasculares del glaucoma deben integrarse a la práctica clínica de esta afección, lo que ayudará a que el enfoque sea más completo, y redundará en un mejor pronóstico de la enfermedad(AU)

Objective: Determine the orbital echo-Doppler findings in patients with primary open angle glaucoma according to atherosclerotic risk factors. Methods: A cross-sectional observational descriptive study was conducted of 300 orbits of 150 patients diagnosed with primary open angle glaucoma. All the cases underwent dynamic contour tonometry and optical coherence tomography. Interrogation and clinical laboratory testing led to identification of the following atherosclerotic risk factors: arterial hypertension, smoking, diabetes mellitus type 2, dyslipidemia, obesity and excessive alcohol consumption. Orbital and carotid Doppler ultrasounds were performed, and only if they were normal they would be followed by echo-Doppler evaluation of the ophthalmic, central retinal and posterior temporal ciliary arteries. Results: Mean age of the study subjects was 62.3 years. 55.3 percent were female and 47.3 percent had white skin. The number of risk factors showed a moderate, positive and significant linear correlation with the resistive index, and a negative correlation with the velocities. All the risk factors expressed harmful effects on ocular flow hemodynamics, intraocular pressure and the thickness of temporal neuroretinal fibers. After adjusting for age, this negative influence continued to be relevant in most cases. Conclusions: The vascular aspects of glaucoma should be incorporated into the clinical management of this condition. This will make the approach more thorough and help achieve a better diagnosis(AU)

Impacto de la acupuntura en el tratamiento del herpes zoster oftálmico / Impact of acupuncture on the treatment of herpes zoster ophthalmicus

RESUMEN El herpes zoster oftálmico es la infección producida por el virus varicela zoster (culebrilla) que afecta el ojo; se caracteriza por exantema en el dermatoma de la frente e inflamación dolorosa de todos los tejidos del segmento anterior, rara vez del posterior. Se presentó un paciente de 64 años de edad, raza blanca, con un herpes zoster oftálmico que le causaba dolor agudo. Las lesiones vesiculosas deformaron la mitad izquierda de su cara. El terapeuta empleó la acupuntura como método de tratamiento y se le colocaron agujas en los puntos IG-4 (Hegu) e IG-11 (Quchi) bilateral; en el proceso se colocó al paciente en posición decúbito supino con sesiones de media hora y estimulación cada cinco minutos de las agujas, de forma sedativa. Se apreció la reducción de la intensidad del dolor desde el primer día y la curación de las lesiones a los seis días de tratamiento.

ABSTRACT Herpes zoster ophthalmicus is the infection caused by the varicella-zoster virus (shingles) that affects the eye; it is characterized by rash in a dermatomal distribution of the forehead and painful inflammation of all the tissues of the anterior segment, rarely of the posterior one. A 64-year-old white patient was presented with a herpes zoster ophthalmicus causing acute pain. Vesicular lesions deformed the left half of his face. The therapist used acupuncture as a treatment method and placed needles in points IG-4 (Hegu) and bilateral IG-11 (Quchi); the patient was placed in supine position during the process, with half-hour sessions and stimulation of the needles every five minutes, in a sedative form. A reduction in pain intensity was appreciated from the first day, as well as, the healing of the lesions after six days of treatment.

Clinical profile and ophthalmologic manifestations of Herpes Zoster Ophthalmicus / Perfil clínico e achados oftalmológicos no Herpes Zoster Oftálmico

ABSTRACT Objective: Herpes Zoster Ophthalmicus (HZO) is caused by varicella-zoster virus (VZV) and commonly affects elderly or immunocompromised patients. It has the potential to generate severe complications such as corneal ulcers, uveitis, retinal necrosis and post herpetic neuralgia. This study aimed to evaluate patients at the acute onset of the disease and describe their clinical profile and ophthalmologic findings. Methods: A cross-sectional study was performed from March 2014 to October 2015. All consecutive patients with the diagnosis of acute HZO (at a vesicle, pustule or crust stage) were enrolled and submitted to an ophthalmologic exam that included ectoscopy, best corrected visual acuity, corneal sensitivity test, slit-lamp examination, Goldmann applanation tonometry and funduscopic examination. Results: Nineteen patients were included. The mean age was 71 years old, ranging from 52 to 88. Ten patients had high blood pressure (52.6%) and nine (47.3%) had diabetes. Visual acuity lowered in comparison to the fellow eye in eleven patients (57%), ranging from one to six lines of vision, due mostly to epithelial keratitis and ocular discharge. Intraocular pressure (IOP) did not varied in most cases compared to the fellow eye. Hutchinson's sign (HS) was present in seven (36%) patients. The correlation between HS and anterior chamber reaction as well as decreased corneal sensitivity was statistically significant with Fisher's test of 0.009 and 0.029 respectively (p<0.05). Conclusion: The clinical profile of our patients was elderly patients with a higher rate of diabetes. Correlation between Hutchinson's sign and anterior chamber reaction as well as decrease in corneal sensitivity was significant. High intraocular pressure or posterior segment complications were not found in any cases.

RESUMO Objetivos: Herpes Zoster Oftálmico (HZO) é uma doença causada pelo vírus varicella-zoster que comumente afeta idosos ou doentes imunossuprimidos, com potencial para gerar graves comorbidades oculares, incluindo úlceras corneanas, uveíte, necrose retiniana e neuralgia pós-herpética. O objetivo deste estudo foi avaliar estes pacientes na forma aguda da doença e descrever seu perfil clínico e achados oftalmológicos. Métodos: Um estudo transversal foi realizado entre março de 2014 e outubro de 2015. Todos os pacientes consecutivos com o diagnóstico de HZO (na forma vesicular, pustulosa ou crostosa) foram incluídos e submetidos ao exame oftalmológico que incluiu ectoscopia, melhor acuidade visual corrigida, teste de sensibilidade corneana, biomicroscopia, tonometria de aplanação de Goldmann e fundoscopia. Resultados: Dezenove pacientes foram incluídos. A idade média foi de 71 anos. Dez (52,6%) pacientes relataram hipertensão arterial sistêmica e nove (47,3%) diabetes mellitus. A acuidade visual do olho acometido se encontrou abaixo do olho contra lateral em 57% dos casos, variando entre uma a seis linhas de visão. A pressão intraocular não variou na maioria dos casos em comparação com o olho contralateral. O sinal de Hutchinson estava presente em sete (36%) pacientes. A correlação entre este sinal e a presença tanto de reação de câmara anterior quanto de hipoestesia corneana foi positiva estatisticamente, com teste exato de Fisher de 0,009 e 0,029 respectivamente (p<0,05). Conclusão: Idosos com uma prevalência elevada de diabetes mellitus representaram o perfil clínico dos pacientes deste estudo. A correlação entre o sinal de Hutchinson e reação de câmara anterior, bem como daquele com hipoestesia corneana foi estatisticamente significativa. Não foi identificado nenhum caso de hipertensão ocular ou complicações de segmento posterior.

Foraminotomía optica para el clipado de aneurisma carótido-oftálmico superior / Optical foraminotomy for clipping of superior carotid-ophthalmic aneurysm

Introducción: Los aneurismas carótido-oftálmicos generalmente causan problemas visuales, y su tratamiento quirúrgico sigue siendo un reto debido al objetivo de preservar y/o mejorar la función visual. Descripción del caso: Presentamos caso de intervención quirúrgica de aneurisma carotídeo-oftálmico superior. Masculino de 64 años de edad con déficit de campo visual inferior izquierdo y cefalea. La reconstrucción angio-TC mostró un aneurisma carotídeo-oftálmico superior izquierdo no roto (4x5 mm). Paciente colocado en posición supina, con la cabeza fija en cabezal Sugita de 4 puntos, con una rotación de 15° hacia el lado contralateral. Una craneotomía pterional clásica con fresado del ala esfenoidal, con apertura de la fisura silviana y carotidea se realizaron bajo el microscopio. Se realiza una incisión dural circunferencial sobre el canal óptico. El techo óseo del canal óptico, así como sus paredes medial y lateral, se eliminan cuidadosamente con una fresa diamantada de 3mm con drill de alta velocidad con irrigación constante para evitar daños térmicos sobre el nervio óptico. El nervio óptico con un disector de Penfield N° 7 se eleva suavemente, lejos de la arteria carótida, para facilitar la exposición del cuello aneurismático para el clipado. Resultados: La apertura extensa del canal óptico y la vaina del nervio óptico se logró con éxito en el paciente, lo que permitió un ángulo de trabajo con la arteria carótida para la correcta visualización del aneurisma. Se logró el correcto clipado en el control de AngioCT postoperatoria. Conclusión: La foraminotomía óptica es una técnica fácil y recomendada para exponer y tratar aneurismas carotídeos-oftálmicos superiores y, además, permitir la descompresión del nervio óptico.

Introduction: Carotid-ophthalmic aneurysms usually cause visual problems, and its surgical treatment remains challenging due to the goal of preserving and/or improving the visual outcome. Case description: We present a surgical intervention of superior carotid-ophtalmic aneurysm. A 64-year-old man with a left inferior visual field deficit and headache. The angio CT reconstruction showed a left incidental superior carotid-ophthalmic aneurysm (4x5mm). Patient positioned in supine, with the head fixed in a 4 pin Sugita headholder with a 15° rotation to the contralateral side. A pterional craniotomy and flattening of sphenoid ridge with the usual drilling procedure with the opening of the Sylvian fissure to the carotid cistern were done under the microscope. A circumferential dural incision is made above the optic canal. The bony roof of the optic canal as well as its medial and lateral walls are carefully removed with a 3mm diamond high speed drill under constant irrigation to avoid thermal damage to the optic nerve. The optic nerve becomes gently retractable with a N° 7 Penfield dissector to some extent away from the carotid artery, to facilitate the aneurysmal neck exposure for clipping. Results: Extensive opening of the optic canal and optic nerve sheath was successfully achieved in the patient allowing a working angle with the carotid artery for correct visualization of the aneurysm. The correct clipping was observed in the postoperative AngioCT control. Conclusion: Optic foraminotomy is an easy and recommended technique for exposing and treating superior carotid-ophthalmic aneurysms and moreover allowing optic nerve decompression.

Objetivo: Determinar los valores de referencia del flujo sanguíneo en las arterias orbitarias de una población cubana. Método: Se realizó un estudio observacional descriptivo y transversal en 630 órbitas normales de 315 pacientes mayores de 18 años, sin antecedentes personales de hipertensión arterial, diabetes mellitus, dislipidemia, tabaquismo o enfermedades hematológicas, ni síntomas o afecciones oftalmológicas conocidas. A todos se les realizó toma de tensión intraocular, así como ultrasonido orbitario y Doppler carotídeo. Solo en caso de resultar dichos exámenes normales se pasó a evaluar mediante ecoDoppler las arterias oftálmica, central de la retina y ciliares posteriores largas. Resultados: La media de los sujetos estudiados fue de 30,4 años. El 51,7 por ciento correspondió al sexo masculino, en tanto el 39,3 por ciento tuvo la piel de color blanco. Se demostró una débil correlación lineal, positiva y significativa entre la edad y los índices de resistencia y pulsatilidad; mientras que con las velocidades pico sistólica y final de la diástole, dicha correlación resultó negativa. En relación con la edad, los valores velocimétricos no expresaron diferencias relevantes entre hombres y mujeres; lo mismo ocurrió con los distintos grupos de color de la piel. Conclusiones: Los valores de referencia para el flujo sanguíneo de las arterias orbitarias determinados en una población cubana, permitirán sospechar cuándo la hemodinámica de una órbita se aparta de la normalidad(AU)

Objective: Determine the blood flow reference values for orbital arteries in a Cuban population. Methods: A cross-sectional observational descriptive study was conducted of 630 normal orbits of 315 patients aged over 18 years with no history of arterial hypertension, diabetes mellitus, dyslipidemia, smoking, hematologic disease, or symptoms of known ophthalmologic conditions. All patients underwent intraocular tension measurement, orbital ultrasound and carotid Doppler scanning. Only when the results obtained were normal, Doppler ultrasonographic evaluation was performed of ophthalmic, central retinal and long posterior ciliary arteries. Results: Mean age of the study subjects was 30.4 years. 51.7 percent were male and 39.3 percent had white skin color. A weak linear, positive, significant correlation was found between age and resistivity and pulsatility indices, whereas such correlation was negative at peak systolic and end diastolic velocities. With respect to age, velocity parameters did not show any relevant differences between men and women or between the different skin color groups. Conclusions: Orbital artery blood flow reference values determined in a Cuban population, will make it possible to suspect when the hemodynamic features of an orbit are not normal(AU)

Avian ophthalmic peculiarities / Particularidades oftálmicas em aves

ABSTRACT: Morphology and physiology of bird eyes are similar to mammals; although, there are peculiarities that should be considered for a correct interpretation of an ophthalmic examination. While the ophthalmology of domestic species is already well established, there are gaps to be filled regarding birds, particularly due to the large number of existing species. This literature review consists of a brief contribution regarding peculiarities of anatomy, physiology, and ophthalmic semiotechnique of the avian eye.

RESUMO: A morfologia e a fisiologia dos olhos das aves são similares àquelas de mamíferos, mas existem particularidades que devem ser consideradas para a correta interpretação do exame oftálmico. Enquanto a oftalmologia de espécies domésticas já é bem estabelecida, ainda há diversas lacunas no que tange às aves, particularmente devido ao grande número de espécies existentes. Este trabalho objetiva realizar uma revisão bibliográfica abrangendo anatomia, fisiologia e semiologia oftálmica de aves.

Se presenta la experiencia personal en el tratamiento de 5 pacientes con 7 aneurismas paraclinoideos tratados quirúrgicamente en el Hospital Regional Temuco durante junio de 2015 y julio de 2016 (13 meses). Todos los pacientes fueron previamente discutidos con neurorradiologo Intervencional local y considerados no favorables para terapia endovascular. En todos ellos se realizó una craneotomía mini pterional con clinoidectomía extradural y exposición de la arteria carótida interna cervical. Cuatro pacientes consultaron con hemorragia subaracnoidea y requirieron cirugía cerebral de urgencia. En 6 aneurismas se realizó clipaje y en 1 trapping. Cuatro pacientes no tuvieron deterioro neurológico y evolucionaron favorablemente mientras que 1 paciente falleció por hipoperfusión secundario al trapping de la carótida supraclinoidea. Se enfatiza el manejo interdisciplinario, el plan preoperatorio y el conocimiento de la neuroanatomía en el tratamiento de esta patología.

A personal experience is presented in treating 5 patients with 7 paraclinoid aneurysm who underwent surgery at Hospital Regional Temuco between june 2015 and july 2016 (13 months). All patients were previously discussed with local interventional neuroradiologist considering them not favorable to endovascular therapy. Mini pterional craniotomy with extradural clinoidectomy and internal cervical carotid artery exposure was performed in all of them. 4 patients presented with subarachnoid hemorrhage and required urgent brain surgery. Direct clipping was optimal in 6 aneurysm and 1 was treated with trapping. 4 patients had no neurological deteriotation with excellent outcome and 1 patient died because of hypoperfusion secondary to the supraclinoid carotid trapping. Interdisciplinary management, preoperative planning and neuroanatomy knowledge are emphasized in order to treat this pathology.

Herpes-zóster oftálmico apos injeção de onabotulinotoxina para tratamento cosmético - Relato de caso / Herpes zoster ophthalmicus after onabotulinumtoxin for cosmetic treatment: a case report

Episódios de herpes-zóster após procedimentos têm sido documentados recentemente na literatura. Uma vez que o uso da toxina botulínica atualmente se faz presente em diversas especialidades médicas, é crucial o estudo de seus efeitos colaterais e complicações. Uma revisão da literatura mostrou 65 casos de reativação de zóster após procedimentos, sendo três relacionados a injeções de toxina botulínica tipo A (dois para tratamento de rítides faciais e um para migrânea crônica). Em nosso caso, uma mulher de 43 anos previamente hígida apresentou herpe-zóster na face e couro cabeludo após injeções de toxina botulínica tipo A com fins estéticos, tendo recuperação completa após tratamento antiviral.

Herpes zoster outbreaks following minor procedures have been documented recently in literature. Since the use of botulinum toxin is nowadays spread in several medical areas for different purposes, it is crucial to study its side effects and complications. Literature review revealed 65 cases of zoster reactivation following minor procedures, and three cases related to BTA injections (two for facial lines treatment and one for chronic migraine). In our case, a 43 year old healthy woman had herpes zoster on the face and scalp after receiving BTA injections for cosmetic purpose, with complete recovery after anti-viral treatment.

Herpes zoster ophthalmicus and varicella zoster virus vasculopathy / Herpes zoster ophthalmicus e vasculopatia por vírus varicella zoster

ABSTRACT Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopathy after adjusting for age, sex, body mass index, smoking, indicators of metabolic syndrome, and vascular and heart diseases. Considering the severity of this complication, vascular disease mediated by VZV requires early diagnosis and aggressive treatment. Finally, the anti-HZ vaccine has been recommended as a prophylactic measure in the elderly, but it should be used with caution in immunocompromised individuals.

RESUMO Herpes zoster (HZ) corresponde à reativação do vírus varicela zoster (VVZ) e, entre os adultos, o envolvimento da divisão oftálmica do nervo trigêmeo é um dos locais mais comuns A vasculopatia associada ao HZ é uma complicação dotada de grande morbimortalidade e afeta diferentes estruturas, favorecendo, inclusive o acidente vascular cerebral. Nesta revisão analisamos aspectos epidemiológicos e clínicos da vasculopatia mediada pelo VZV, bem como as peculiaridades relacionadas com o HZ ocular. De acordo com dados disponíveis na literatura, o acometimento ocular pelo HZ mostrou ser um fator de risco para vasculopatia após se ajustar para idade, sexo, índice de massa corporal, tabagismo, indicadores da síndrome metabólica, doença vascular e cardiopatias. Em face da gravidade dessa complicação, a doença vascular mediada pelo VZV requer diagnóstico precoce e tratamento agressivo. A vacina anti-HZ tem sido recomendada profilaticamente em idosos, mas deve ser usada com cautela em indivíduos imunocomprometidos.

Optic neuritis complicating herpes zoster ophthalmicus in an immunocompetent patient / Zoster optic neuritis in immunocompentent

A 58-year-old woman presented with rash over the left side of the face and intense acute uveitis. Following careful review of the symptoms and dilated fundus examination unilateral optic neuritis was discovered. The rash was typical of varicella zoster dermatitis. Patients presenting with herpes zoster ophthalmicus should always undergo dilated fundus examination, as there is a potential risk of unexpected posterior segment inflammation. Early diagnosis and prompt treatment can avoid visual sequelae.

Paciente de 58 anos de idade apresentando erupção cutânea no lado esquerdo da face e intensa uveíte unilateral. Após cuidadosa revisão dos sintomas e exame de fundo do olho foi detectada neurite óptica. O rash era típico de dermatite por varicella zoster. Pacientes apresentando quadro de herpes zoster oftálmico devem ser submetidos ao exame de fundo do olho devido ao risco de inesperada inflamação do segmento posterior. Diagnóstico precoce e tratamento imediato podem evitar danos visuais.

Eficacia clínica del florfenicol oftálmico vs florfenicol parenteral en el tratamiento de queratoconjuntivitis infecciosa bovina / Clinical efficacy of parenteral vs ophthalmic florfenicol for the treatment of infectious bovine keratoconjunctivitis

The clinical and bacteriological efficacy, the quantity of mg and florfenicol treatment length for infectious bovine keratitis (Moraxella bovis) was assessed using either the parenteral administration of florfenicol (PF), or the ophthalmic administration of the drug in spray (OF). Sixty four cows and heifers were randomly divided into the two referred treatments. All animals were cured, however, the OF group required a mean of 378 mg/bovine and 12 days of treatment, while the PF group needed 22 800 mg/bovine (3.8 treatments per bovine) and 7.6 days. Although 100% efficacy was obtained in both groups cost-benefit ratio in the OF group is pondered.

Para el tratamiento de la queratitis infecciosa bovina (Moraxella bovis) se evaluaron la eficacia clínica y bacteriológica, la cantidad en mg utilizada y el tiempo en que se lograba la curación, utilizando florfenicol parenteral (FP) o florfenicol en aerosol oftálmico (FO). En ambos tratamientos se utilizaron 64 bovinos divididos aleatoriamente. Todos los animales curaron, pero se requirieron valores medios de 378 mg/bovino y 12 días de tratamiento para FO y 22 800 mg/bovino (3.8 tratamientos por bovino) y 7.6 días para FP. Se pondera tanto la eficacia del florfenicol en ambos grupos, como la posibilidad de una drástica reducción en los costos de tratamiento en el grupo tratado con FO.

Síndrome do ápice orbitário causada por herpes zóster oftálmico: relato de caso e revisão da literatura / Herpes zoster ophthalmicus and orbital apex syndrome: case report and literature review

OHerpes Zoster Oftálmico (HZO) decorre da infecção pelo vírus da varicela-zoster que permanece latente no gânglio de Gasser até que seja reativado e comprometa a divisão oftálmica do nervo trigêmeo. HZO freqüentemente causa manifestações oftalmológicas como lesões vesiculares palpebrais, ceratoconjuntivite, esclerite, uveíte, paralisia oculomotora, miosite orbitária e neurite óptica. Raramente o acometimento do ápice da órbita pode ser a manifestação inicial desta grave afecção. Este trabalho relata um caso de síndrome do ápice orbitário associado à meningite, causado por HZO e que foi tratado com corticosteróide e aciclovir sistêmicos.

Herpes Zoster ophthalmicus (HZO) is caused by a varicella-zoster virus infection which remains latent in the ganglion of Gasser until it is reactivated and compromise the ophthalmic division of the trigeminal nerve. HZO commonly causes neuro-ophthalmic complications such as vesicular lesions in the eyelids, keratoconjunctivitis, sclertis, uveitis, ocular palsy, orbital miositis and optic neuritis. HZO rarely presents as an orbital apex syndrome. This paper describes a patient with of orbital apex syndrome associate and meningitis caused by HZO which was treated with systemic steroids and acyclovir.

Encefalitis por virus varicela zoster: a propósito de un caso / Encephalitis by varicella zoster virus: a propos of a case

Se trata de una paciente blanca, femenina, de 79 años, que en el curso de un herpes zoster oftálmico comienza con manifestaciones clínicas neurológicas, que se interpretaron inicialmente como reacciones adversas al tratamiento oral con aciclovir; siendo el sistema nervioso central la localización extracutánea más frecuente de este herpes virus; y la forma más común de afectación neurológica en esta infección es una encefalitis, se pensó en esta entidad a pesar de su atipicidad no reportada en la bibliografía consultada, lo que motivó a realizar una revisión exhaustiva de este tema. La paciente evolucionó satisfactoriamente con desaparición de los síntomas y signos clínicos.

It deals with a 79-years-old, white, female patient, beginning with neurological clinical manifestations in the course of ophthalmologic zoster herpes. Initially they were interpreted as adverse reactions of the acyclovir treatment. Being the central nervous centre the most frequent extra-cutaneous location of this herpes virus, and encephalitis the most common neurologic affection in this infection, we thought about this entity despite of its atypicity, which was not found in the consulted bibliography. It motivated us to make an exhaustive review of this theme. The evolution of the patient was positive, disappearing the clinic signs and symptoms.
