Extra-articular Manifestations of Chikungunya

ABSTRACT Chikungunya fever (CHIK) is a neglected tropical disease associated with chronic arthritis. CHIK is usually a self-limiting condition; however, extra-articular manifestations present as atypical illness in a minority of patients. These atypical features may mimic other conditions and potentially distract physicians from the true diagnosis. This review analyzes the evidence of many unusual extra-articular manifestations reported in cases of CHIK. Depending on the affected system, these unusual manifestations include encephalitis, myocarditis, acute interstitial nephritis, cutaneous manifestations, acute anterior uveitis, abdominal pain, and depression. In addition, coinfections and comorbidities may cause atypical illness and obscure the diagnosis. Further studies are required to clarify the pathophysiology and natural history of CHIK, as it remains a burdening condition. Exploring its atypical symptoms may be the missing scientific piece of this puzzle.

Resultados: El 69,9 % de los estudiantes presentó un nivel de conocimientos regular, observándose medidas preventivas inadecuadas en el 44,3 %. Un 92,0 % de encuestados consideró que las arbovirosis son enfermedades graves, pero solo 10,2 % reconoció el signo de alarma del zika. Las principales medidas preventivas fueron: la fumigación (50,6 %) y el uso de repelentes (49,6 %). Además, el 92,6 % de estudiantes consideró importante eliminar los criaderos de mosquitos para evitar la propagación de los arbovirus. Sin embargo, solo el 51,1 % revisó la presencia de criaderos y limpió diaria e interdiariamente su domicilio (43,8 %). Conclusiones: El nivel de conocimientos fue regular y se relacionó con medidas preventivas inadecuadas como no revisar frecuentemente la presencia de criaderos de mosquitos ni realizar limpieza en las viviendas.

ABSTRACT Introduction: Arbovirus infections are a serious health problem in Peru. Higher population awareness and their participation in preventive activities can minimize their impact. Objective: Assessment on the level of knowledge and its relationship with preventive measures concerning arbovirus infections in university students in an endemic area of Peru, September to November 2020. Method: An observational, cross-sectional, correlational and non-experimental design study was carried out. The population consisted of 325 medical technology students and the sample consisted of 176 students of both sexes. The level of knowledge was categorized as deficient, regular and high. Preventive measures were classified as adequate and inadequate. The questionnaire contained 23 multiple-choice questions, validated by expert judgment. Results: The knowledge level in 69.9% of the students was fair, and inadequate preventive measures were observed in 44.3%. The 92.0% of surveyed personnel considered the arbovirus infection as a serious disease, but only 10.2% recognized the warning sign of zika. The main preventive measures were: fumigation (50.6%) and the use of repellents (49.6%). In addition, 92.6% of students considered as an important action the act to eliminate mosquito breeding sites in order to prevent the spread of infection. However, only 51.1% checked for the presence of breeding sites and cleaned their homes on a daily and inter-daily basis (43.8%). Conclusions: The level of knowledge was regular and was related to inadequate preventive measures such as not frequently checking for the presence of mosquito breeding sites and not cleaning houses.

Systemic Manifestations, Tooth Eruption and Enamel Defects in Children with Congenital Zika Virus Syndrome: 36-Month Follow-up Case Series

Abstract Objective: To describe systemic manifestations, the characteristics related to tooth eruption, and the occurrence of enamel defects in children with Congenital Zika Virus Syndrome (CZS). Material and Methods: Prospective case series based on nine children with confirmed CZS diagnosis assisted at a reference center in a municipality in the Northeast Region of Brazil. Through a structured interview directed to mothers, information related to prenatal, delivery, and postpartum periods was collected. Tooth eruption was monitored through clinical examinations for 36 months. The modified developmental defect of enamel index (DDE) was used to identify opacities and hypoplasia. Data were presented using descriptive statistics. Results: A high proportion (77.8%) had microcephaly, and 55.5% had low birth weight. Musculoskeletal disorders, swallowing difficulty, and self-injury practices were present in all children. Among the systemic findings, visual impairment (77.8%) and seizures (77.8%) were widely reported. Concerning disorders related to the stomatognathic system, bruxism (66.7%) and difficulty in sucking (33.3%) were present. For most children (77.8%), the deciduous right lower central incisor was the first tooth to erupt (minimum 8 months and maximum 17 months). Enamel defects were diagnosed in only two children (22.2%). Conclusion: A wide range of systemic manifestations was observed in children with CZS, including visual impairment and musculoskeletal disorders. Delayed eruption of the first deciduous tooth was also observed. Enamel defects were present in a small proportion of children.

Incidence and spatial distribution of cases of dengue, from 2010 to 2019: an ecological study

ABSTRACT BACKGROUND: Dengue is an arbovirus that has caused serious problem in Brazil, putting the public health system under severe stress. Understanding its incidence and spatial distribution is essential for disease control and prevention. OBJECTIVE: To perform an analysis on dengue incidence and spatial distribution in a medium-sized, cool-climate and high-altitude city. DESIGN AND SETTING: Ecological study carried out in a public institution in the city of Garanhuns, Pernambuco, Brazil. METHODS: Secondary data provided by specific agencies in each area were used for spatial analysis and elaboration of kernel maps, incidence calculations, correlations and percentages of dengue occurrence. The Geocentric Reference System for the Americas (Sistema de Referência Geocêntrico para as Américas, SIRGAS), 2000, was the software of choice. RESULTS: The incidence rates were calculated per 100,000 inhabitants. Between 2010 and 2019, there were 6,504 cases and the incidence was 474.92. From 2010 to 2014, the incidence was 161.46 for a total of 1,069 cases. The highest incidence occurred in the period from 2015 to 2019: out of a total of 5,435 cases, the incidence was 748.65, representing an increase of 485.97%. Population density and the interaction between two climatic factors, i.e. atypical temperature above 31 °C and relative humidity above 31.4%, contributed to the peak incidence of dengue, although these variables were not statistically significant (P > 0.05). CONCLUSION: The dengue incidence levels and spatial distribution reflected virus and vector adjustment to the local climate. However, there was no correlation between climatic factors and occurrences of dengue in this city.

Introducción: Las enfermedades producidas por arbovirus son un problema grave a nivel mundial. Objetivo: Caracterizar los pacientes estudiados por sospecha de arbovirosis en una institución de salud. Métodos: Se realizó un estudio observacional, descriptivo y transversal en el policlínico Edor de los Reyes Martínez Áreas del municipio Jiguaní, provincia Granma, en el periodo comprendido entre el 1 de enero y el 31 de diciembre de 2019. Se trabajó con una muestra de 2947 personas y se estudiaron las siguientes variables: edad, sexo, consejos populares, forma de identificación de signos/síntomas, diagnóstico inicial y positividad a dengue. Resultados: El 40,07 por ciento de los casos estudiados pertenece al consejo popular Jiguaní Norte. Fueron pacientes femeninas 1590 (53,95 por ciento). El rango de edad predominante fue 41-60 años (n = 1222; 41,47 por ciento). En 1908 (64,74 por ciento) pacientes la identificación de signos y síntomas sugerentes de arbovirosis fue mediante las pesquisas. El 98,88 por ciento de los pacientes (n = 2914) fue diagnosticado inicialmente con síndrome febril inespecífico. La única arbovirosis identificada fue el dengue, el que se encontró en 637 pacientes. Octubre fue el mes con mayor número de pacientes estudiados (n = 1063; 36,07 por ciento). Conclusiones: La mayoría de los casos pertenecía al sexo femenino y a la zona urbanizada del municipio. El consejo popular urbano Jiguaní Norte fue el que más casos positivos a dengue aportó(AU)

Introduction: Arbovirus infections are a serious global health problem. Objective: Characterize the patients studied for suspected arbovirus infection at a health institution. Methods: A cross-sectional observational descriptive study was conducted at Edor de los Reyes Martínez Arias polyclinic in the municipality of Jiguaní, province of Granma, from 1 January to 31 December 2019. The study sample was 2947 people, and the variables examined were age, sex, people's council, form of sign / symptom identification, initial diagnosis and positivity for dengue.

In 1908 patients (64.74 percent) signs and symptoms suggesting arbovirus infection were identified through screening. 98.88 percent of the patients (n = 2914) were initially diagnosed with unspecific febrile syndrome. The only arbovirus infection identified was dengue, which was detected in 637 patients. October was the month when the highest number of patients were studied (n = 1063; 36.07 percent). Conclusions: Most cases were female and from urbanized areas in the municipality. Jiguaní Norte urban people's council contributed the most dengue positive cases(AU)

Caracterización clinicoepidemiológica de pacientes con dengue ingresados en el Instituto de Medicina Tropical Pedro Kourí / Clinical epidemiological characterization of patients with dengue admitted to Pedro Kourí Tropical Medicine Institute

Introducción: El dengue es una infección viral endémica reemergente de notable preponderancia por su morbilidad y mortalidad, cuya incidencia se ha multiplicado en las últimos tiempos a nivel internacional. Objetivos: Caracterizar a pacientes con dengue según la clasificación revisada de la Organización Mundial de la Salud y determinar la correspondencia entre esta y la clasificación tradicional respecto a la gravedad de los casos. Métodos: Se realizó un estudio descriptivo y transversal en el Instituto de Medicina Tropical Pedro Kourí de La Habana durante el 2012, en el que se revisaron 247 historias clínicas seleccionadas por muestreo aleatorio estratificado. Resultados: En la casuística predominaron el dengue con signos de alarma, el grupo etario de 40-59 años, el sexo femenino y el síndrome de choque por dengue como principal forma clínica de gravedad. La fiebre estuvo presente en todos los afectados; también sobresalieron la cefalea, la astenia, las artromialgias, la exantema y el dolor retroocular. La leucopenia y la trombocitopenia constituyeron hallazgos muy frecuentes, al igual que la citólisis hepática; en tanto, las manifestaciones digestivas y hemorrágicas, entre otras, se asociaron significativamente con el desarrollo de dengue grave. Conclusiones: Se evidenció que utilizando la clasificación tradicional se hubiesen dejado de identificar y tratar adecuadamente a pacientes con dengue grave y dengue con signos de alarma, al catalogarse la mayoría de estos como fiebre del dengue, subestimando así la gravedad clínica de dichos casos.

Introduction: Dengue is a viral endemic reemerging infection of remarkable preponderance for its morbidity and mortality whose incidence has multiplied in the last times at international level. Objectives: To characterize patients with dengue according to the classification reviewed by the Health World Organization and to determine the correspondence between this and the traditional classification regarding the seriousness of the cases. Methods: A descriptive and cross-sectional study was carried out at Pedro Kourí Tropical Medicine Institute in Havana during 2012, in which 247 medical records were reviewed selected by stratified random sampling. Results: In the case material there was a prevalence of dengue with alarm signs, 40-59 age group, female sex and the shock syndrome due to dengue as the main clinic form of seriousness. The fever was present in all those affected; migraine, asthenia, artromialgias, exanthema and retroocular pain were also outstanding. The leukopenia and thrombocytopenia constituted very frequent findings, the same as hepatic cytolysis; as long as, the digestive and hemorrhagic manifestations, among others, were significantly associated with the development of serious dengue. Conclusions: It was evidenced that using the traditional classification the identification and appropriate treatment to patients with serious dengue and dengue with alarm signs would not be possible, when being classified most of these as fever of the dengue, underestimating this way the clinical seriousness of these cases.

Complicaciones oculares asociadas a la fiebre por dengue / Ophthalmic complications associated to dengue fever

RESUMEN La infección por el virus del dengue va en aumento en las regiones tropicales de Asia, África y América. Se estima que se producen de 50 a 100 millones de casos de esta enfermedad al año. En los últimos tiempos han aumentado los reportes de manifestaciones oculares en estos pacientes, las cuales ocurren en un rango de 5 a 7 días posteriores al inicio de los síntomas, aunque también pueden ocurrir más tarde, y generalmente existe buen pronóstico visual. Se realiza una revisión bibliográfica con el objetivo de ampliar el conocimiento sobre un tema poco tratado en nuestro medio. Se consultaron fundamentalmente artículos científicos de revistas, publicados en las bases de datos PubMED y Cochrane, así como textos básicos que abordan este tema en los últimos 5 años, a través de Google académico como motor de búsqueda. Se constató que se han reportado manifestaciones oculares en pacientes con dengue que van desde hallazgos en el segmento anterior sin afectación visual, hasta cuadros más intensos que interesan las estructuras del polo posterior del ojo. La fisiopatología de estos hallazgos aún se encuentra en estudio y no existe consenso para su tratamiento. A pesar de que el pronóstico visual de estas alteraciones es bueno, se reportan casos donde no es así y se precisa mayor comprensión sobre la fisiopatología de estas para un abordaje terapéutico más adecuado en cada caso(AU)

ABSTRACT Infection by dengue virus is on the increase in tropical regions of Asia, Africa and America. It has been estimated that 50 to 100 million cases of this disease occur every year. Recent years have witnessed a rise in the number of reports of ocular manifestations in dengue patients. These manifestations appear 5 to 7 days after symptom onset, though they could also occur later, and the visual prognosis is generally good. A bibliographic review was conducted with the purpose of broadening knowledge about a topic not commonly dealt with in our environment. The search was mainly aimed at scientific papers from journals, published in the databases PubMed and Cochrane, as well as basic texts addressing the study topic in the last 5 years, using the search engine Google Scholar. Ocular manifestations were found to have been reported in dengue patients. These range from findings in the anterior segment without any visual alteration to more intense episodes affecting the structures of the posterior pole of the eye. The physiopathology of these findings is still being studied, and there is no consensus about its treatment. Despite the good visual prognosis of these alterations, cases have been reported of a different outcome. Therefore, a better understanding is required of their physiopathology to achieve a more appropriate therapy for each case(AU)

Evaluación de índices entomológicos mediante herramientas electrónicas en Villavicencio, Meta, Colombia / Evaluation of entomological indices with electronic tools in Villavicencio, Meta, Colombia

Objetivo: Determinar la eficacia de dos herramientas electrónicas en el levantamiento de índices aédicos en la ciudad Villavicencio. Métodos: Se realizó un estudio de tipo observacional, analítico en dos barrios de la ciudad Villavicencio: Quintas de San Fernando y Cedritos. El formato de levantamiento de índices aédicos de la secretaría de salud fue diseñado en dos medios electrónicos. La eficacia fue determinada mediante datos efectivos recogidos y tiempo de entrega. Se calcularon índices aédicos, Breteau, vivienda y pupas. Se realizó encuesta para determinar actitudes frente a arbovirosis. Se realizó estadística descriptiva, pruebas de chi cuadrado y t-Student (p< 0,05). Resultados: Se evaluaron 67 predios en dos barrios. El índice de datos efectivos fue mejor en donde el acceso a internet era permanente (100 por ciento vs. 23,9 por ciento); el tiempo de entrega también se afectó por esta conexión. Se encontraron diferencias significativas en el número de viviendas positivas para Aedes aegypti entre los dos barrios (p= 0,0052); y para el número de tanques bajos positivos (p= 0,0123). De los encuestados, el 16,4 por ciento (IC95 por ciento 8,9 por ciento-27,5 por ciento) sabía que la transmisión fue por picadura de Ae. aegypti. Para el 79,1 por ciento, cada familia fue responsable de eliminar criaderos. Conclusiones: El uso de herramientas electrónicas permite acelerar el flujo de la información y crear un sistema eficaz, de fácil acceso y seguridad que podría implementarse permanentemente en la vigilancia entomológica y de salud pública(AU)

Objective: Determine the effectiveness of two electronic tools for the evaluation of aedic indices in the city of Villavicencio. Methods: An observational analytic study was conducted in two districts in the city of Villavicencio: Quintas de San Fernando and Cedritos. The form designed by the Ministry of Health to evaluate aedic indices was digitalized into two electronic media. Efficacy was determined on the basis of effective data collected and delivery time. An estimation was made of aedic indices, Breteau, household and pupae. A survey was conducted to determine attitudes to arbovirus infections. Use was made of descriptive statistics, chi-squared tests and Student's t-test (p< 0.05). Results: Sixty-seven households were evaluated in two districts. The effective data index was better in areas where access to the Internet was permanent (100 percent vs. 23.9 percent). Delivery time was also affected by Internet connection. Significant differences were found between the two districts in the number of positive households for Aedes aegypti (p= 0.0052), as well as in the number of positive ground water tanks (p= 0.0123). Of the respondents, 16.4 percent (95 percent CI, 8.9 percent-27.5 percent) were aware that transmission had been by the bite of Ae. aegypti mosquitoes. For 79.1 percent each family was responsible for eliminating the breeding sites. Conclusions: Use of electronic tools speeds up the flow of information and creates an effective, easily-accessible and safe system which could be permanently implemented for entomological and public health surveillance(AU)
