Síndrome de Miller Fisher, un desafío diagnóstico de oftalmoplejía: reporte de un caso / Miller Fisher syndrome, a diagnostic challenge of ophthalmoplegia: a case report

El síndrome de Guillain-Barré (SGB), y sus derivados, entre ellos el síndrome de Miller Fisher (SMF); junto a otras patologías de origen neurológico como la Polineuropatía desmielinizante inflamatoria crónica (CIDP), las polineuropatías de causa metabólica, miastenia gravis, esclerosis lateral amiotrófica (ELA), síndrome de Lambert-Eaton, encefalopatía de Wernicke entre otras; presentan signos y síntomas neurológicos de presentación común. De este modo, la importancia del examen neurológico acabado; y los exámenes de apoyo diagnóstico como: laboratorio -destacando el líquido cefalorraquídeo (LCR)-, electromiografía, y toma de imágenes, son cruciales para esclarecer el diagnóstico. Así, es posible ofrecer un tratamiento de forma precoz, basado en la evidencia, y con el objetivo de disminuir la letalidad de la enfermedad. En el presente texto se plasma un subgrupo de patología de SGB, el SMF, el cual posee una incidencia significativamente baja, una clínica característica, y un pronóstico bastante ominoso sin un tratamiento adecuado. En el presente texto se plasma el reporte de un caso abordado en el Hospital San Pablo de Coquimbo, Chile.

Guillain-Barré syndrome (GBS) and its derivatives, including Miller Fisher syndrome (MFS), along others pathologies of neurological origin such as chronic inflammatory demyelinating polyneuropathy (CIDP), metabolic polyneuropathies, myasthenia gravis, amyotrophic lateral sclerosis (ALS), Lambert-Eaton syndrome, Wernicke's encephalopathy and well as others, have common neurological signs and symptoms. In this way, the importance of a thorough neurological examination, and supporting diagnostic tests such as: laboratory, -cerebrospinal fluid (CSF)-electromyography, and imaging, are crucial to clarify the diagnosis. Thus, it is possible to offer early, evidence-based treatment with an aim of reducing the disease's lethality. In the text below we present a subgroup of GBS pathology, MFS, which has a significantly low incidence, a characteristic clinical picture, and a rather ominous prognosis without adequate treatment. In the following text/paper is shown the report of a case approached in San Pablo Hospital, from Coquimbo, Chile.

Caracterización de la hipotonía-hiporrespuesta post vacuna pentavalente y tamizaje del neurodesarrollo en niños bajo 6 años de edad, 2013-2018, Uruguay / Characterization of hypotonia-hyporesponsiveness after pentavalent vaccine and neurodevelopmental screening in children under 6 years of age, 2013-2018, Uruguay

INTRODUCCIÓN: La hipotonía-hiporrespuesta (HHR) es uno de los efectos adversos supuestamente atribuibles a la vacunación e inmunización de tipo neurológico más notificados. El impacto a largo plazo a nivel del neurodesarrollo no es completamente conocida. OBJETIVO: Caracterizar los eventos de HHR post vacuna pentavalente notificados entre 2014 y 2018 al Ministerio de Salud Pública (MSP) de Uruguay. Realizar el tamizaje del neurodesarrollo de los que al momento de la evaluación tenían menos de 6 años de edad. METODOLOGÍA: Estudio descriptivo de las notificaciones al Sistema Nacional de Farmacovigilancia del MSP. Se realizó el tamizaje del neurodesarrollo con la Guía Nacional para la Vigilancia del Desarrollo. RESULTADOS: 30 casos, la mayoría de breve duración, en las primeras horas post primera dosis y con recuperación espontánea. Requirieron hospitalización 29. Se realizó el tamizaje del neurodesarrollo en 16. La media de tiempo entre el evento y esta evaluación fue 2 años y 2 meses. Fue normal la prueba de tamizaje en 15. En uno se detectó un retraso del lenguaje. CONCLUSIONES: Los episodios de HHR se presentaron con características similares a las descritas en la bibliografía. A pesar de las limitaciones del estudio, no se encontraron retrasos ni desvíos del desarrollo en los niños evaluados.

BACKGROUND: Hypotonic-hyporesponsive episodes (HHE) is one frequently reported neurologic adverse effect supposedly attributable to vaccination and immunization. Its long-term impact on neurodevelopment is not completely known. AIM: To characterize the post-pentavalent vaccine HHE events reported to the Uruguayan Ministry of Health (M of H) between 2014 and 2018. To perform neurodevelopment screening of those who were under 6 years of age at the time of evaluation. METHODS: Descriptive study of the reports made to the National Farmacosurveillance System of the M of H. Neurodevelopment screening was performed using the National Guidelines for Developmental Surveillance. RESULTS: 30 cases were studied. Most cases occurred after the first doses, were of short duration and during the first hours after vaccination, with spontaneous recovery. Median time between the event and this evaluation was 2 years and 2 months. Screening tests were normal in 15. Delay in the language area was detected in one case. CONCLUSIONS: HHE events had similar characteristics to those described in the literature, with no severe short-term complications. Despite the limitations of the present study, no delays nor deviations were found in the development of the children who were evaluated.

Episodio de hipotonía-hiporreactividad como evento supuestamente atribuido a la vacunación e inmunización. Reporte de un caso / Case study of a hypotonic-hyporesponsive episode from an alleged adverse effect following vaccination and immunization / Relato de caso de episódio hipotônico hiporresponsivo supostamente atribuído a um evento adverso pós-vacinação e imunização

Resumen: El desarrollo de la vacunación a nivel mundial ha permitido el control de algunas enfermedades infecciosas, constituyéndose en una poderosa herramienta de salud pública. Asimismo, se han identificado algunos efectos secundarios neurológicos, como el denominado episodio de hipotonía-hiporreactividad, evento supuestamente atribuido a la vacunación e inmunización. Si bien es poco frecuente, se considera un efecto adverso severo. El objetivo de este artículo es reportar un caso y revisar la literatura sobre el tema. Se presenta una lactante de 2 meses que luego de tres horas de recibir la primera dosis de la vacuna combinada pentavalente, presenta episodio de hipotonía con cianosis de segundos de duración. Este episodio se caracteriza por presentarse horas después de la administración de la vacuna con un inicio súbito de hipotonía generalizada, hiporreactividad y palidez cutánea o cianosis. El diagnóstico es de exclusión, ya que se presenta en lactante de aspecto grave. La mayoría de los episodios se han relacionado con el componente pertussis, ya sea celular o acelular. La vigilancia de los ESAVI es un pilar fundamental para desarrollar esquemas de vacunación eficaces y seguros para toda la población.

Summary: The global development of vaccines has enabled us to control some infectious diseases and has become a powerful public health tool. Despite this, vaccines have some neurological side effects, such as the so-called Hypotonic-Hyporesponsive Episode (HHE), an adverse event following vaccination and immunization (AEFI). Even though it is rare, it is considered to be a severe adverse effect. The objective of this article is to report about a HHE case and to review the literature on the subject. The case is of a 2-month-old infant who, after 3 hours of receiving the first dose of the combined pentavalent vaccine, developed a hypotonic episode with cyanosis of seconds of duration. HHE usually happens hours after the vaccine is administered and it shows a sudden onset of generalized hypotonia, hyporesponsiveness, pale skin or cyanosis. A diagnosis of exclusion was made, since the symptoms looked serious on the infant. Most episodes have been linked to cellular or acellular pertussis. It is essential to carry out AEFI surveillance in order to develop effective and safe vaccination schedules for the entire population.

Resumo: O desenvolvimento global de vacinas há permitido controlar algumas doenças infeccionas tornando-se uma poderosa ferramenta de saúde pública. Apesar disso, elas têm alguns efeitos colaterais neurológicos, como o chamado Episódio Hipotônico-Hiporresponsivo (EHH), um evento adverso pós-vacinação e imunização (EAPV). Embora seja raro, é considerado um efeito adverso grave. O objetivo deste artigo é relatar um caso de EHH e revisar a literatura sobre o assunto. O relato de caso é de uma criança de 2 meses de idade quem, após 3 horas de recebimento da primeira dose da vacina pentavalente combinada, desenvolveu um episódio hipotônico com cianose de segundos de duração. O EHH geralmente ocorre horas após a administração da vacina e mostra um início repentino de hipotonia generalizada, hiporresponsividade, pele pálida ou cianose. O diagnóstico foi de exclusão, pois os sintomas no bebê eram sérios. A maioria dos episódios foi associada à pertussis celular ou acelular. É essencial realizar a vigilância da EAPV para desenvolver cronogramas de vacinação eficazes e seguros para toda a população.

Maintenance enteral electrolyte solutions for neonatal calves: sodium acetate and osmolarity effects / Soluções eletrolíticas enterais de manutenção para bezerros neonatos: efeitos do acetato de sódio e da osmolaridade

The use of hypotonic electrolytic solutions in enteral fluid therapy is still understudied in calves. The objective of the present study was to evaluate the effects of maintenance enteral electrolytic solutions with different concentrations of sodium acetate and different osmolarities in calves. For this, 18 Holstein calves, six male and 12 female, 20 days old and weighing around 52kg, were used. The animals were randomly divided into three groups and each group received one of the treatments. The three electrolytic solutions contained the same components in different concentrations, resulting in a hyposmotic, an isosmotic and a hyperosmotic solution. Each animal was maintained in enteral fluid therapy for 12 hours with infusion rate of 15mL kg-1 h-1. Abdominal circumference, body weight, feces consistency, glucose and plasma lactate, pH, pCO2, HCO- 3 and BE were measured at the following times: T0h, T6h, T12h and T24h. The hyposmotic solution did not generate the onset of diarrhea, while the isosmotic and the hyperosmotic did. Regardless of the dose used, acetate did not cause metabolic alkalosis in the evaluated animals. The results suggest that the use of hyposmotic solution in diarrheic calves, dehydrated and without metabolic acidosis, may be clinically important.(AU)

O uso de soluções eletrolíticas hipotônicas na hidratação enteral ainda é pouco estudado em bezerros. O objetivo do presente estudo foi avaliar os efeitos de soluções eletrolíticas enterais de manutenção com diferentes concentrações de acetato de sódio e diferentes osmolaridades em bezerros. Para isso, foram utilizados 18 bezerros, seis machos e 12 fêmeas, holandeses, com 20 dias de nascidos e pesando por volta dos 52kg. Os animais foram divididos aleatoriamente em três grupos e cada grupo recebeu um dos tratamentos. As três soluções eletrolíticas continham os mesmos componentes, mas em diferentes concentrações, resultando em uma solução hiposmótica, uma isosmótica e uma hiperosmótica. Cada animal foi mantido em hidratação enteral durante 12 horas com taxa de infusão de 15mL kg-1h-1. Foram aferidos perímetro abdominal, peso corporal, consistência das fezes, glicose e lactato plasmático, pH, pCO2, HCO- 3 e excesso de base nos seguintes tempos: T0h, T6h, T12h e T24h. A solução hiposmótica não gerou aparecimento de diarreia, enquanto a isosmótica e a hiperosmótica geraram. Independentemente da dose utilizada, o acetato não causou alcalose metabólica nos animais avaliados. Os resultados sugerem que o uso da solução hiposmótica em bezerros diarreicos, desidratados e sem acidose metabólica, pode ser clinicamente importante.(AU)

Miopatía nemalínica tratada con L-tirosina para aliviar los síntomas en un recién nacido / Nemaline rod myopathy treated with L-tyrosine to relieve symptoms in a neonate

La miopatía nemalínica es un trastorno heterogéneo definido por la presencia de estructuras con forma de bastones, conocidas como cuerpos nemalínicos (o bastones de nemalina). El diagnóstico se funda en la debilidad muscular, además de la visualización de cuerpos nemalínicos en la biopsia muscular. La miopatía nemalínica no tiene cura. Las estrategias terapéuticas para este trastorno son sintomáticas y empíricas. En este artículo, presentamos el caso de una recién nacida con insuficiencia respiratoria grave y debilidad muscular generalizada, a la que se le diagnosticó miopatía nemalínica a través de la biopsia muscular. La paciente tuvo una notable disminución de la sialorrea y una mejora de los movimientos espontáneos después del tratamiento con L-tirosina. Este caso se presenta para destacar la importancia de la biopsia muscular en el diagnóstico diferencial de la hipotonía grave durante el período neonatal y el posible beneficio del aporte suplementario de L-tirosina para disminuir la sialorrea y restaurar la fuerza muscular.

Nemaline myopathy (NM) is a heterogeneous disorder defined by the presence of rod-shaped structures known as nemaline bodies or rods. The diagnosis is based on muscle weakness, combined with visualization of nemaline bodies on muscle biopsy. There is no curative treatment for nemaline myopathy. Therapeutic strategies for this condition are symptomatic and empirical. Herein, we present a newborn with severe respiratory failure and generalized muscle weakness, who was diagnosed as NM by muscle biopsy. The patient experienced remarkable decrease in sialorrhea and improvement of spontaneous movements after L-tyrosine treatment. This case is presented to emphasize the importance of muscle biopsy in the differential diagnosis of severe hypotonia during neonatal period and a possible benefit of L-tyrosine supplementation for decreasing sialorrhea and restoring muscle strength.

Comorbidities associated with cerebral palsy in children presenting at department of Pediatrics, K. T. children hospital Rajkot, India

Background: Cerebral palsy is a diagnostic term used to describe a group of motor syndromes resulting from disorder of early brain development. It describes a group of permanent disorders of the development of brain and posture causing activity limitation. The magnitude of cerebral palsy in our country is 2 to 2.5 per thousand live birth. The objective is to study co-morbidities associated in cerebral palsy patients.Methods: It was a hospital based cross sectional study carried out in KT Children Hospital, PDU Medical College, Rajkot for 1 year (April 2017-April 2018). Sample size: minimum 100 cases. Selection of subject: All the children suffering from cerebral palsy presenting at KT Children hospital, P.D.U. Medical college Rajkot, Gujarat. Cases were evaluated by history, clinical examination and necessary investigations.Results: From data collected in present study most common variety of Cerebral Palsy is spastic type (72.5%) followed by, dyskinetic (16%), ataxic (7%), and hypotonic (4.5%) type. Within spastic type; diplegic (48%) is the most common variety. Caesarean section delivered cases are more predisposed to Cerebral palsy in present study which might be due to other risk factors associated with it. Gender and consanguinity showed not major significance in association with CP child. Most of Cerebral palsy cases in present study were born full term (81.5%) and of normal birth weight (78.5%). The most common comorbidities in present study were cognitive impairment (77%) followed by epilepsy (38%), visual impairment (10%), hearing disability (9%) thyroid dysfunction (3%) and G.I. disturbances (2%). Perinatal asphyxia is the most common history finding in Cerebral palsy cases including in present study, followed by seizures during infancy, pathological jaundice, neonatal sepsis and history of NICU admission for any cause.Conclusions: Cerebral palsy in developing countries has a higher prevalence and different clinical profile regarding severity and associated disability. The perinatal and high-quality neonatal care together with physical therapy and rehabilitation programs have a significant role in preventing comorbidities in cerebral palsy cases, which is still lacking in developing countries.

Transscleral Cyclopexy Using Partial-Thickness Scleral Flap for Repairing Cyclodialysis Cleft: a Case Report

PURPOSE: To report a case of a cyclodialysis cleft that was successfully managed with gonioscopically guided transscleral cyclopexy using partial-thickness scleral flap. CASE SUMMARY: A 44-year-old man complaining of blurred vision in the left eye after blunt trauma was referred to our hospital. The intraocular pressure (IOP) was 4 mmHg and the visual acuity was counting finger. Gonioscopy examination revealed cyclodialysis cleft from 3 to 6 o'clock and fundus examination revealed macular folds. After the failure of conservative medical therapy and laser photocoagulation, gonioscopically guided transscleral cyclopexy using partial-thickness scleral flap was performed. Four months later, the IOP was 18 mmHg, the visual acuity was 0.8, and fundus examination showed the disappearance of the macular folds. CONCLUSIONS: Transscleral cyclopexy using partial-thickness scleral flap is a safe and effective method to treat hypotony maculopathy due to cyclodialysis and to minimize pupil distortion.

Encefalopatía hiponatrémica / Hyponatremic encephalopathy

Introducción: la hiponatremia es la anomalía electrolítica más común en pacientes hospitalizados. Está relacionada con la administración de fluidos hipotónicos en pacientes con niveles elevados de hormona antidiurética. La complicación más grave de la hiponatremia es la encefalopatía hiponatrémica, que puede ser fatal, o provocar una lesión cerebral irreversible, si no se trata adecuadamente. Presentación del caso: lactante de 6 meses de edad, eutrófica, con antecedentes de salud y un desarrollo psicomotor acorde con su edad, que ingresa en el Hospital Pediátrico de Cienfuegos con el diagnóstico de una enfermedad diarreica aguda por rotavirus. Se decidió suspender la alimentación e iniciar hidratación de mantenimiento por intolerancia de la vía oral. Se empleó una solución en base a dextrosa al 5 por ciento con 0,18 por ciento de NaCl. Transcurridas 14 horas en la sala, la paciente se traslada a Cuidados Intensivos por convulsiones, que estuvieron relacionadas con hiponatremia severa. Inicialmente el valor del sodio fue normal. En la tomografía de cráneo realizada 13 días después presentaba signos de atrofia cortical. Al momento de realizar este trabajo la niña se seguía en consulta de Fisiatría y Neuropediatría por una cuadriparesia flácida. Conclusiones: los fluidos hipotónicos siguen siendo recomendados como líquidos de mantenimiento en pacientes agudamente enfermos, a pesar de la fuerte asociación entre su uso y el desarrollo de hiponatremia. Es hora de que se dejen de usar fluidos hipotónicos en estados de enfermedad asociados con exceso de hormona antidiurética, pues no existe razón para que esta práctica continúe(AU)

Introduction: hyponatremia is the most common electrolytic abnormality in hospitalized patients. It is related to the administration of hypotonic fluids in patients with high levels of antidiuretic hormone. The most serious complication of hyponatremia is hyponatremic encephalopathy which can be fatal, or cause irreversible brain damage if not treated properly. Case presentation: a 6-month-old, eutrophic infant with health history and psychomotor development according to her age that was admitted in the Pediatric Hospital of Cienfuegos with the diagnosis of an acute diarrheal disease by rotavirus. It was decided to suspend the feeding and initiate maintenance hydration due to intolerance in the oral route. A solution based on 5 percent dextrose with 0.18 percent of NaCl was used. After 14 hours in the ward, the patient was transferred to Intensive Care due to convulsions, which were related to severe hyponatremia. Initially the sodium value was normal. The cranial tomography performed 13 days later showed signs of cortical atrophy. At the time of doing this work the girl was being followed in consultation of Physiatry and Neuropediatrics by a flabby quadriparesia. Conclusions: hypotonic fluids are still recommended as maintenance fluids in acutely ill patients, despite the strong association among their use and the development of hyponatremia. It is time to stop using hypotonic fluids in disease states associated with excess of antidiuretic hormone, because there is no reason for this practice to continue(AU)

Spectrophotometric assessment of effect of aqueous extract of Aloe vera on rabbit erythrocytes in varying concentrations of saline

Background: Hemolytic disorders are one of the prime reasons for frequent blood transfusions which involves lots of costs and sufferings to the patient. This study was undertaken to determine the effect of water soluble extract of Aloe vera on rabbit erythrocytes in varying concentrations of NaCl from 0.9% (isotonic) to 0.15% (hypotonic).Methods: Aqueous extract of Aloe vera (AVE) 200mg/kg was orally administered to rabbits in the test group while control group was given 1ml of distilled water (DW). Blood was withdrawn from rabbits, centrifuged and suspension in 1ml of normal saline was made. 20 microliter of red blood cells suspension from both control and test groups was added to normal saline of varying concentrations from 0.9% to 0.15% NaCl which were quantitatively analysed for hemolysis by UV spectrophotometer. Data was analysed by unpaired t test and P <0.05 was considered statistically significant.Results: The difference in percentage of hemolysis in both test and control groups was not statistically significant. Therefore, acute administration of water soluble extract of Aloe vera (200mg/kg) did not have protective effect on rabbit erythrocytes against hypotonic solution of normal saline.Conclusions: Aloe vera might be useful for the treatment of oxidative stress-related human disorders by virtue of its antioxidant activity and may have a role in prevention of hemolysis which needs to be explored by further studies.

Observation of early results for different kinds of transepithelial corneal collagen cross-linking in the treatment of progressive keratoconus / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To compare the early results of different kinds of transepithelial corneal collagen cross-linking (TE-CXL) in the treatment of progressive keratoconus.METHODS:Retrospective study.Twenty four patients (34 eyes) who were diagnosed with progressive keratoconus were divided into three groups.And 10 eyes in hypotonic CXL group received the treatment of hypotonic corneal collagen cross-linking;14 eyes in Ⅰ-CXL 5min group received the treatment of iontophoresis corneal collagen cross-linking for 5min,and 10 eyes from the Ⅰ-CXL 10min group received the treatment of iontophoresis corneal collagen cross-linking for 10min.Uncorrected distance visual acuity,corrected distance visual acuity,Pentacam,in vivo scanning laser confocal microscopy and anterior segment optical coherence tomography were examined before and after 1wk,1,3 and 6mo postoperatively.RESULTS:Six months postoperatively,corrected distance visual acuity (CDVA) (LogMAR) in Ⅰ-CXL 10min group increased by-0.21 ± 0.23 (t =2.735,P=0.026);Kmax decreased by 2.32± 5.21D (t=1.40,P=0.193),but the differences were not statistically significant.Uncorrected distance visual acuity (UDVA),CDVA and Kmax in hypotonic CXL group and Ⅰ-CXL 5min group were stable,the differences were not statistically significant.The depth of demarcation line was 152.7±42.9μ m in hypotonic CXL group,213.6±42.3μ m in Ⅰ-CXL 5min group and 237.0±46.4μ m in Ⅰ-CXL 10min group 1wk after the surgery,the differences among groups were statistically significant (F =7.111,P =0.006).The phenomenon of stroma cell apotosis-activate regeneration in Ⅰ-CXL 10min group was the most significant after the surgery.The changes of corneal thinnest thickness and endothelial cell density in three groups were stable.CONCLUSION:Three kinds of transepithelial CXL can halt the progression of keratoconus,among which the reaction of corneal tissue in iontophoresis CXL for 10min is the most obvious.

Episodio Hipotonía-Hiporreactividad posterior a la inmunización con vacuna combinada con pertussis de células enteras. Reporte de un caso / Hypotonic-Hyporesponsive Episode after immunization with whole-cell pertussis combination vaccine. Clinical Case Report

Resumen Introducción: El Episodio Hipotonía-Hiporreactividad (EHH) es un efecto adverso tras la vacuna ción, asociado principalmente a vacunas anti-pertussis de células enteras. Se caracteriza por un inicio súbito de flacidez muscular, reducida respuesta a estímulos y palidez cutánea o cianosis. Aunque el EHH es infrecuente, está considerado como un efecto adverso severo. Objetivo: Reportar un caso de EHH posterior a la administración de la vacuna combinada pentavalente con: difteria, tétanos, pertussis celular, hepatitis B y Haemophilus influenzae tipo b (DTwP-HB-Hib), que está incluida en el Programa Nacional de Inmunizaciones (PNI) de Chile, con la finalidad de difundir esta infrecuente complicación de evolución benigna, auto-limitada y de carácter no recurrente. Caso clínico: Lactante de 6 meses de edad, 3 h post-vacunación con la tercera dosis de vacuna DTwP-HB-Hib, presentó compromiso del estado de conciencia interpretado como convulsión atónica y que finalmente se consideró como EHH. El lactante evolucionó favorablemente después de 2 h y fue dado de alta tras 24 h de vigilancia clínica; se cambió el esquema de inmunización del lactante con vacunas anti-per tussis acelulares como medida preventiva. Conclusiones: El desconocimiento sobre el EHH puede desalentar la inmunización infantil. Por lo tanto, es importante que el personal médico informe a los padres de los pacientes sobre este evento benigno, autolimitado y no recurrente. En estos casos, se re comienda continuar con el programa de inmunización del lactante con formulaciones que contengan componentes anti-pertussis acelulares.

Abstract Introduction: Hypotonic-Hyporesponsive Episode (HHE) is an adverse event after vaccination, mainly associated with whole-cell pertussis vaccines. It is characterized by a sudden onset of muscle flaccidity, reduced response to stimuli and pallor or cyanosis. Although the HHE is infrequent, it is considered a severe adverse event. Objective: To report a case of HHE following the administration of the whole-cell pertussis combination vaccine (DTwP-HB-Hib), which is included in National Im munization Program (PNI) of Chile, and to contributing to the knowledge of this adverse event in the country. Case report: A 6-month-old infant, 3 hours post-vaccination with the third dose of DTwP-HB-Hib vaccine, presented a decreased level of consciousness that was interpreted as atonic seizure but finally considered as EHH. The infant progressed favorably after 2 hours of clinical observation and was discharged 24 hours later. Parents were suggested to continue the immunization schedule of the infant with acellular pertussis vaccines as a preventive measure. Conclusions: The lack of knowledge about the EHH may discourage childhood immunization. Therefore, it is important for the medical staff to inform parents of the patients about this benign, self-limited and non-recurrent adverse event. In these cases, it is recommended to continue the immunization schedule of the infant with acellular pertussis vaccines.

Enteral electrolyte solutions with different osmolarities administered in a continuous flow in newborn calves / Soluções eletrolíticas enteral com diferentes osmolaridade administradas em fluxo contínuo em bezerros recém-nascidos

ABSTRACT: This study compared the effects of enteral electrolyte solutions with different osmolarities in Holstein cattle. Eighteen newborn calves were evenly divided into three groups and administered the following treatments: hypotonic electrolyte solution (ESHYPO) containing 4g NaCl, 0.5g KCl, 1g sodium acetate, and 7.5g dextrose diluted in 1,000mL water; isotonic electrolyte solution (ESISO) containing 5g NaCl, 1g KCl, 2g sodium acetate, and 10g dextrose diluted in 1,000mL water; and hypertonic electrolyte solution (ESHYPER) containing 6g NaCl, 1g KCl, 3g sodium acetate, and 15g dextrose diluted in 1,000mL water. Solutions were administered at a rate of 15mL kg-1hr-1 for 12 hours in a continuous flow. All three solutions increased the concentration of plasma sodium, but ESHYPO did not alter the serum osmolarity. Both ESISO and ESHYPO resulted in an increase in volemia.

RESUMO: O presente estudo comparou os efeitos de soluções de eletrolíticas enterais com diferentes osmolaridades administradas em fluxo contínuo. Dezoito animais foram divididos em três grupos: Solução eletrolítica hipotônica (SEHIPO) contendo 4g de NaCl; 0,5g de KCl; 1g de acetato de sódio; 7,5g de dextrose diluídos em 1.000mL de água; Solução eletrolítica isotônica (SEISO) contendo 5g de NaCl; 1g de KCl; 2g de acetato de sódio; 10g de dextrose diluídos em 1.000mL de água; A solução eletrolítica hipertônica (SEHIPER) contendo 6g de NaCl; 1g de KCl; 3g de acetato de sódio; 15g de dextrose diluídos em 1.000mL de água. As soluções foram administradas na dose de 15mLkg-126h-1 durante 12 horas. Os tratamentos SEHIPO, SEISO e SEHIPER aumentaram a concentração plasmática de sódio, contudo apenas a SEHIPO não ocasionou alteração na osmolaridade sérica. As SEHIPO e SEISO aumentaram a volemia.

Novel Adjuvant Method to Assist Localisation of a Cyclodialysis Cleft

PURPOSE: To introduce a novel adjuvant technique to locate cyclodialysis cleft using a laser pointer in a gonioscopic view. CASE SUMMARY: A 36-year-old man complaining of blurred vision in his left eye after blunt trauma 2 weeks prior was referred to our hospital. Gonioscopy showed a cyclodialysis cleft from 3 to 4 o'clock and fundus revealed hypotonic maculopathy. After the failure of medical treatment, we tried various interventions such as injection of viscoelastic agent into the anterior chamber and intravitreal gas tamponade with transconjunctival cryotherapy. Since those were not successful, we decided to treat the patient with direct cyclopexy. For the preoperative localization of the cleft, we tried a new technique that uses a laser pointer. On gonioscopic examination, an assistant shot the laser toward the limbal area where the suspicious cleft was located. We were able to precisely locate the cyclodialysis cleft if the laser pointer light was seen through the cleft in the gonioscopic view. With the aid of a laser a pointer, the cleft was successfully closed. CONCLUSIONS: Localization with a laser pointer is simple, safe, rapid, and helpful for planning surgical repair of a cyclodialysis cleft without expensive equipment.

Episodio de Hipotonía e Hiporreactividad posterior a la aplicación de vacunas en Cuba durante el período 2012-2013 / Hypotonic-hyporesponsive episodes after the application of vaccines in Cuba during the period 2012-2013

Introducción: la vacuna contra la difteria, la tos ferina (células enteras) y el tétanos que protege contra estas enfermedades, inició su uso en la década de 1940, logró una disminución considerable de estas enfermedades. Pero también, surgieron numerosos eventos asociados a esta vacuna. Uno de ellos es el Episodio de Hipotonía e Hiporreactividad, reportado con menor frecuencia, a las vacunas contra Haemophilus influenzae tipo b y la hepatitis B. Es un evento poco conocido y raro. Objetivo: mejorar el conocimiento sobre esta entidad. Métodos: se realizó un estudio observacional retrospectivo de los Episodio de Hipotonía e Hiporreactividad (según niveles de certeza diagnóstica), reportados durante 2012 y 2013 por el médico de familia al sistema de vigilancia de eventos adversos, procedentes de todas las provincias. Resultados: fueron reportados 27 Episodio de Hipotonía e Hiporreactividad. El 92,6 por ciento correspondió a la vacuna pentavalente, para una tasa de 3,2 x 105 Dosis Aplicadas. El 74 por ciento se notificaron en las primeras 12 horas. Se observó con mayor frecuencia después de la primera dosis, para un 48 por ciento y el 85,4 por ciento ocurrió en los menores de 6 meses. La fiebre, el llanto persistente, los vómitos, el decaimiento y la somnolencia fueron los síntomas asociados con esta entidad. Conclusiones: la vigilancia de este episodio ha permitido conocer el tiempo de aparición después de aplicar la vacuna, dosis, edad y si está asociado con otros síntomas. Constituye un primer acercamiento a este evento, para mejorar su conocimiento, lo cual permitirá continuar con la seguridad y confiabilidad del Programa Nacional de Inmunización en Cuba(AU)

Correlation of anorectal electromanometry and anorectal three-dimensional ultrasound findings in patients with fecal incontinence / Correlação dos achados da eletromanometria anorretal e ultrassonografia anorretal tridimensional nos pacientes portadores de incontinência fecal

Objective: To show the correlation of anorectal electromanometry and three-dimensional anorectal ultrasonography in patients with fecal incontinence. Method: Prospective study involving 34 women (mean age: 55 years) with a diagnosis of fecal incontinence. The samples were submitted to three-dimensional anorectal ultrasonogra- phy/Echodefecography and anorectal electromanometry. Results: Based on anorectal electromanometry data, 70.5% of 34 patients had hypotonia at rest, 64.7% had hypotonic contraction, 52.9% had both hypotonia at rest and hypotonic contraction, and 44.1% had anismus. By three-dimensional anorectal ultrasonography, 32.3% had internal anal sphincter injury, 79.4% had external anal sphincter injures, and 26.4% had both internal and external anal sphincter injuries. In 38.2%, anismus was suggested and 50% showed rectocele. Overall, only 5.8% had normal results for anorectal electromanometry combined with three-dimensional anorectal ultrasonography. Kappa index was 0.297 and the presence of anismus through anorectal electromanometry and three-dimensional anorectal ultrasonography was compared by Student's t test application, with p<0.0001. Conclusion: We conclude that there was a reasonable agreement in the comparison of sphincter hypotonia by anorectal manometry and sphincter injury by anorectal three-dimensional ultrasonography in a group of patients with fecal incontinence. The incidence of anismus in patients with fecal incontinence is considerable, and the therapeutic approach in these patients should be modified. (AU)

RESUMO Objetivo: Demonstrar a correlação entre eletromanometria anorretal (EMAR) e ultrassonografia tridimensional anorretal (3D-US) em pacientes com incontinência fecal. Método: Estudo prospectivo envolvendo 34 mulheres (média de idade: 55 anos) com diagnóstico de incontinência fecal. As amostras foram submetidas à 3D-US/Ecodefecografia e EMAR. Resultados: Com base nos dados de EMAR, 70,5% das 34 pacientes exibiam hipotonia em repouso, 64,7% exibiam contração hipotônica, 52,9% hipotonia em repouso e contração hipotônica, e 44,1% exibiam anismus. Com base nos achados de 3D-US, 32,3% exibiam lesão no esfíncter anal interno, 79,4% exibiam lesão no esfíncter anal externo, e 26,4% em ambos os esfíncteres anais interno e externo. Pela 3D-US, em 38,2% das pacientes houve indício de anismus, e em 50%, retocele. No total, apenas 5,8% obtiveram resultados normais combina- dos para EMAR e 3D-US. Foi constatado um índice Kappa = 0,297 e, no teste t de Student, a comparação de anismus por EMAR e por 3D-US obteve significância de p<0,0001. Conclusão: Concluímos ter havido concordância razoável ao ser comparada a manomatria anorretal para hipotonia esfinctérica e a ultrassonografia tridimensional anorretal para lesão esfinctérica em um grupo de pacientes com incontinência fecal. A incidência de anismus em pacientes com incontinência fecal é considerável, e a abordagem terapêutica para esses pacientes deve ser modificada. (AU)

Comparison of two maintenance electrolyte solutions in children in the postoperative appendectomy period: a randomized, controlled trial / Comparação de duas soluções para manutenção hidroeletrolítica no pós-operatório de apendicectomia em crianças: um estudo controlado e randomizado

ABSTRACT OBJECTIVE: To compare two electrolyte maintenance solutions in the postoperative period in children undergoing appendectomy, in relation to the occurrence of hyponatremia and water retention. METHODS: A randomized clinical study involving 50 pediatric patients undergoing appendectomy, who were randomized to receive 2,000 mL/m2/day of isotonic (Na 150 mEq/L or 0.9% NaCl) or hypotonic (Na 30 mEq/L NaCl or 0.18%) solution. Electrolytes, glucose, urea, and creatinine were measured at baseline, 24 h, and 48 h after surgery. Volume infused, diuresis, weight, and water balance were analyzed. RESULTS: Twenty-four patients had initial hyponatremia; in this group, 13 received hypotonic solution. Seventeen patients remained hyponatremic 48 h after surgery, of whom ten had received hypotonic solution. In both groups, sodium levels increased at 24 h (137.4 ± 2.2 and 137.0 ± 2.7 mmol/L), with no significant difference between them (p = 0.593). Sodium levels 48 h after surgery were 136.6 ± 2.7 and 136.2 ± 2.3 mmol/L in isotonic and hypotonic groups, respectively, with no significant difference. The infused volume and urine output did not differ between groups during the study. The water balance was higher in the period before surgery in patients who received hypotonic solution (p = 0.021). CONCLUSIONS: In the post-appendectomy period, the use of hypotonic solution (30 mEq/L, 0.18%) did not increase the risk of hyponatremia when compared to isotonic saline. The use of isotonic solution (150 mEq/L, 0.9%) did not favor hypernatremia in these patients. Children who received hypotonic solution showed higher cumulative fluid balance in the preoperative period.

RESUMO OBJETIVO: Comparar duas soluções de manutenção hidroeletrolítica no período pós-operatório (PO) de crianças submetidas à apendicectomia quanto à ocorrência de hiponatremia e retenção hídrica. MÉTODOS: Estudo clínico randomizado que envolveu 50 pacientes pediátricos submetidos à apendicectomia, randomizados para receber 2.000 ml/m2/dia de solução isotônica (Na 150 mEq/L ou NaCl 0,9%) ou hipotônica (Na 30mEq/L ou NaCl 0,18%). Eletrólitos, glicose, ureia e creatinina foram mensurados no início do estudo, 24 e 48 horas após a cirurgia. Foram analisados volume infundido, diurese, peso e balanço hídrico. RESULTADOS: Apresentaram hiponatremia inicial 24 pacientes. Desses, 13 receberam solução hipotônica. Dezessete pacientes permaneceram hiponatrêmicas 48 horas após a cirurgia, 10 haviam recebido solução hipotônica. Nos dois grupos os níveis de sódio aumentaram na 24ª hora PO (137,4 ± 2,2 e 137,0 ± 2,7) e não houve diferença entre eles (p = 0,593). Níveis de sódio 48 h após a cirurgia foram 136,6 ± 2,7 e 136,2 ± 2,3 no grupo isotônico e hipotônico respectivamente sem diferença significativa. Os volumes infundidos e a diurese não diferiram entre os grupos durante o estudo. O balanço hídrico foi maior no período anterior à cirurgia no grupo de pacientes que receberam solução hipotônica (p = 0,021). CONCLUSÕES: No período pós-apendicectomia, o uso da solução hipotônica não aumentou o risco de hiponatremia quando comparado com uma solução salina isotônica. O uso da solução isotônica não favoreceu a hipernatremia nesses pacientes. Crianças que receberam solução hipotônica apresentaram maior balanço hídrico cumulativo no período pré-operatório.

Ensayo clínico aleatorizado sobre la administración de una solución de mantenimiento intravenosa hipotónica comparada contra una isotónica en pacientes pediátricos críticos / Hypotonic versus isotonic maintenance fluids in critically ill pediatric patients: a randomized control trial

Introducción. Las soluciones hipotónicas se han vinculado a la producción de hiponatremia iatrogénica. Objetivos. Evaluar las variaciones en el sodio sérico (NaS) tras la administración de una solución de mantenimiento intravenosa isotónica (NaCl al 0,9% en dextrosa al 5%) en comparación con una solución de mantenimiento hipotónica (NaCl al 0,45% en dextrosa al 5%). Material y métodos. Ensayo clínico aleatorizado, doble ciego y controlado. Se enrolaron pacientes pediátricos con una estadía esperada en la unidad de cuidados intensivos mayor de 24 horas, NaS normal y líquidos intravenosos > 80% de los líquidos totales de mantenimiento. La concentración sérica de Na se midió antes de colocar la solución de mantenimiento y al reducir la administración de ésta a < 80% del total del aporte. Resultados. Se incorporaron 63 pacientes, que fueron asignados en forma aleatoria a recibir una solución de mantenimiento hipotónica (n= 32) o isotónica (n= 31). Las características basales fueron similares en ambos grupos. No hubo diferencias con respecto a la cantidad de solución administrada (grupo hipotónico 865 ± 853 ml; grupo isotónico 778 ± 649 ml, p= 0,654) o el tiempo de infusión (grupo hipotónico: 24 ± 10,8 horas; grupo isotónico: 27,6 ± 12,8 horas, p= 0,231). Se encontró una diferencia en el NaS luego de la administración de las soluciones de mantenimiento (grupo hipotónico: 137,8 ± 4,3 mmol/L; grupo isotónico: 140,0 ± 4,1 mmol/L, p=0,04). Ninguna de las dos soluciones de mantenimiento aumentó el riesgo de hiponatremia (Na < 135 mmol/L) o de hipernatremia (Na > 145 mmol/L). Conclusiones. Ambas soluciones de mantenimiento, en 24 horas de infusión, no aumentaron el riesgo de producir hiponatremia iatrogénica.

Introduction: Hypotonic fluids have been associated with the development of iatrogenic hyponatremia. Objectives. To assess variations in serum sodium (sNa) following the intravenous administration of isotonic maintenance fluids (0.9% NaCl/5% dextrose) compared to hypotonic maintenance fluids (0.45% NaCl/5% dextrose). Material and Methods. Randomized, controlled, double-blind clinical trial. Pediatric patients with an expected length of stay in the intensive care unit of more than 24 hours were enrolled, with normal serum Na, and IV fluids >80% of total maintenance fluids. Serum Na level was measured before administering maintenance fluids and when reducing the administration to <80% of total fluids. Results. The study included 63 patients who were randomly assigned to receive hypotonic (n= 32) or isotonic (n= 31) maintenance fluids. Baseline characteristics were similar inboth groups. There were no differences in terms of volume of fluid administered (hypotonic group: 865 ± 853 mL; isotonic group: 778 ± 649 mL; p=0.654) or infusion duration (hypotonic group: 24 ± 10.8 hours; isotonic group: 27.6 ± 12.8 hours; p= 0.231). A difference was found in the serum Na following the administration of maintenance fluids (hypotonic group: 137.8 ± 4.3 mmol/L; isotonic group: 140.0 ±4.1 mmol/L, p= 0.04). None of these two maintenance fluids increased the risk of hyponatremia (Na <135 mmol/L) or hypernatremia (Na >145 mmol/L). Conclusions. Neither hypotonic nor isotonic maintenance fluids increased the risk of developing iatrogenic hyponatremia with the 24 hour infusion.

Cytotoxic, Thrombolytic and Membrane Stabilizing Activities of Swietenia mahagoni (L.) Jacq. Flower Extract.

Aims: To investigate cytotoxic, thrombolytic and membrane stabilizing activities of methanol extract and its different Kupchan partitionates of flowers of Swietenia mahagoni. Study Design: Evaluation of cytotoxic activity using brine shrimp nauplii, thrombolytic and membrane stabilizing activities on human RBCs. Place and Duration of Study: Phytochemical Research Laboratory, Department of Pharmacy, School of Health Science, State University of Bangladesh, from April to September, 2013. Methodology: The eggs of brine shrimp nauplii were hatched in artificial sea water for 24 hours. Cytotoxic activity was determined by measuring the percentage of their mortality after application of different partitionates to them. Human RBCs were obtained from 3 healthy volunteers. Thrombolytic activity was calculated by weighing the clot before and after addition of different partitionates while membrane stabilizing activity was evaluated in terms of inhibition of percentage of haemolysis of RBCs by measuring optical density in both hypotonic and heat induced conditions. Results: The highest cytotoxic activity was achieved with the crude methanol extract (LC50 = 0.10±0.01 mg/ml) among the partitionates while vincristine sulfate, the positive control, achieved an LC50 value of 0.40±0.02 mg/ml. While investigating thrombolytic activity, the petroleum ether soluble fraction achieved the highest clot lysis activity (34.30±0.78%) compared to the standard streptokinase (70.27±1.26%). While determining the membrane stabilizing activity, in hypotonic solution induced condition, the crude methanol extract inhibited 84.71±3.25% haemolysis of RBCs whereas in heat induced condition, the aqueous soluble fraction inhibited 86.30±4.98% haemolysis of human RBCs. Here, acetyl salicylic acid (0.01mg/ml) used as reference standard showed 71.91±2.29% and 45.45±4.87% inhibition of haemolysis of human RBCs in hypotonic solution and heat induced conditions, respectively. Conclusion: From our investigation, it can be suggested that, the flower extractives can further be studied extensively to find out their efficacy.
