RESUMO
En el mundo un paciente diabético gasta entre dos y tres veces más que el no diabético. El pie diabético disminuye la calidad de vida, aumenta la morbimortalidad y la carga económica del sistema de salud. Objetivo: comunicar la investigación realizada sobre costos directos en el tratamiento de la úlcera del pie diabético. Material y método: estudio observacional, descriptivo, retrospectivo de pacientes asistidos en la Unidad de Pie del Hospital de Clínicas, Universidad de la República, entre octubre de 2014 y septiembre de 2016. Se estimaron gastos directos del tratamiento ambulatorio e internación a través de información de la historia clínica. El horizonte de tratamiento fue de tres meses. Se calcularon los gastos en unidades reajustables (UR), pesos y dólares. Los gastos se actualizaron a octubre del 2022 utilizando el índice de precios al consumo (IPC), ajustado a la tasa de inflación acumulada. Resultados: incluimos 49 pacientes, 11 mujeres y 38 hombres, edad promedio 61,5 años. El gasto general fue mayor a 400.000 dólares, con el mayor costo en gastos de internación. El gasto total promedio por paciente fue de 8.799 dólares. El tratamiento convencional fue 3.707,93 dólares, la amputación mayor 32.003,61 dólares y amputación menor 12.385,34 dólares. El gasto en internación fue muy superior al del paciente ambulatorio. En emergencia, 28 pacientes gastaron 4.396 dólares. El incremento de costos al año 2022 fue de 37,45%, suponiendo un gasto general de 16.682.993,4 pesos o 410.830,2 dólares. Conclusión: primera evaluación en nuestro país de estimación de gastos en pie diabético. El costo de la úlcera genera una carga económica notoria y en aumento. La gravedad inicial de la úlcera determina ingresos con elevados costes. Los gastos de internación y amputaciones representan la mayor erogación económica.
On a global scale, a diabetic patient incurs healthcare expenses that are 2 to 3 times higher than those of a non-diabetic individual. Diabetic foot syndrome reduces the quality of life, increases morbidity and mortality, and places an economic burden on the healthcare system. Objective: Communicating the research conducted on direct costs in the treatment of diabetic foot ulcers. Method: Observational, descriptive, retrospective study of patients treated at the Foot Unit of the Hospital de Clínicas (UDELAR) between October 2014 and September 2016. Direct treatment costs for outpatient care and hospitalization were estimated using information from the medical records. The treatment horizon extended over a period of 3 months. Expenses were calculated in readjustable units, Uruguayan pesos (UYU), and United States dollars (USD). Expenses were updated to October 2022 using the Consumer Price Index (IPC) adjusted for the cumulative inflation rate. Results: 49 patients were included in the study: 11 women and 38 men, average age was 61.5 years old. The overall expenditure exceeded 400,000 USD, with the highest cost attributed to hospitalization expenses. The average total expenditure per patient amounted to 8,799 USD. The cost of conventional treatment was 3,707.93 USD, major amputation represented USD 32,003.61, and minor amputation USD 12,385.34. Hospitalization expenses significantly exceeded those of outpatient care. In the emergency department, 28 patients spent USD 4,396. The increase in costs by the year 2022 amounted to 37.45%, resulting in a total expenditure of UYU 16,682,993.4 (Uruguayan pesos) or USD 410,830.2. Conclusions: It was the first assessment in our country to estimate diabetic foot costs. The cost of ulcer management imposes a significant and increasing economic burden. The initial severity of the ulcer results in hospitalization which implies high associated costs. Hospitalization and amputation costs constitute the most substantial economic expenditure.
Em todo o mundo, um paciente diabético gasta entre 2 e 3 vezes mais do que um paciente não diabético. O pé diabético reduz a qualidade de vida, aumenta a morbimortalidade e a carga económica no sistema de saúde. Objetivos: Comunicar os resultados da pesquisa realizada sobre os custos diretos no tratamento das úlceras do pé diabético. Materiais e métodos: Estudo observacional, descritivo e retrospectivo de pacientes atendidos na Unidade de Pie do Hospital de Clínicas (UDELAR), entre outubro de 2014 e setembro de 2016. Foram estimados gastos diretos com tratamento ambulatorial e internação, por meio de informações do prontuário do paciente. O período de tratamento estudado foi de 3 meses. As despesas foram calculadas em Unidades Ajustáveis, em pesos uruguaios (UYU) e em dólares norte-americanos (USD). As despesas foram atualizadas para outubro de 2022 pelo Índice de Preços ao Consumidor (IPC) ajustado à inflação acumulada. Resultados: Foram incluídos 49 pacientes: 11 mulheres e 38 homens com idade média de 61,5 anos. A despesa global foi superior a US$ 400.000, com o maior custo em despesas de hospitalização. A despesa total média por paciente foi de US$ 8.799. Os custos por tratamento foram: Tratamento convencional US$ 3.707,93 USD, amputação maior US$ 32.003,61 e amputação menor US$ 12.385,34. O gasto com internação foi muito superior ao do ambulatório. No atendimento de emergência 28 pacientes gastaram US$ 4.396. O aumento dos custos até 2022 foi de 37,45%, assumindo uma despesa geral de UY$ 16.682.993,4 ou US$ 410.830,2 USD. Conclusão: Esta é a primeira avaliação de estimativa de gastos com pé diabético realizada no Uruguai. O custo das úlceras gera uma carga económica notável e crescente. A gravidade inicial da úlcera determina internações com custos elevados. As despesas com hospitalização e amputação representam o maior gasto financeiro.

Autochthonous breeds of livestock are considered a pivotal genetic resource for agriculture, rural development, and food and nutrition security. In the Italian Alps, local livestock breeds are maintained using the traditional alpine farming system based on vertical transhumance, with the use of alpine pastures from late spring to autumn and indoor housing with a hay-based diet for the remaining part of the year. Because of their tight link with the territory of origin, local breeds could be used to biomonitor environmental contaminations. Moreover, animal welfare should also be monitored during transhumance in animals, which are exposed to a sudden farming system change and different types of stressors. For these reasons, this investigation hypothesized that the content of trace elements, heavy metals, and cortisol in the hair of goats changes during vertical transhumance, possibly reflecting different dietary contents and activity of the hypothalamic-pituitary-adrenal (HPA) axis. This study aimed to assess the response of an Italian local goat breed to the change from indoor housing to alpine pasture in summer in terms of hair concentrations of (i) trace elements and heavy metals and (ii) cortisol. The regrown hair of Frisa goats was monthly collected for 2 consecutive years (n = 10 for heavy metals and trace elements and n = 6 for cortisol in 2021, n = 17 for both analyses in 2022), once before vertical transhumance and twice after that event. Hair was then analyzed for trace elements, heavy metals, and cortisol by inductively coupled plasma-optical emission spectrophotometer (ICP-OES) and enzyme immunoassay (EIA), respectively. Data were analyzed by multilevel models. The results showed an increase in As content during alpine pasture (p < 0.01), probably reflecting the soil and water As contents of the grazing area, while Mg, Zn, and Al (p < 0.01) followed the opposite trend, decreasing in the second month after vertical transhumance. Hair cortisol concentrations increased during 2 months of alpine pasture (p < 0.001), indicating an increase in the activation of the HPA axis, in agreement with previous studies. Future investigations can consider a longer study period and the development of ad hoc animal welfare indicators.
RESUMO
This study aimed to characterize the colostrum quality in three different local goat breeds of Northern Italy (i.e., Frisa Valtellinese, Orobica, and Lariana) and a cosmopolitan one (i.e., Camosciata delle Alpi) (n = 30 per breed), reared under traditional semi-extensive and intensive systems, respectively. Lariana showed the highest percentage of fat (10.18 ± 3.14%) and total solids (30.73 ± 4.89%) but the lowest percentage of lactose (1.87 ± 0.82%; p < 0.05); Orobica had the lowest percentage of fat (7.13 ± 2.48%), total solids (24.11 ± 5.48%), and protein (10.77 ± 4.53%) but the highest percentage of lactose (3.16 ± 0.73%; p < 0.05). This suggests that breeds which have a more pronounced meat aptitude (i.e., Frisa and Lariana) have a higher concentration of components than breeds with more dairy aptitude (i.e., Orobica and Camosciata). Uni- and multivariate analyses showed that IgG is the parameter that best differentiates local breeds from cosmopolitan ones (p < 0.01). Colostrum from Frisa goats showed the highest IgG concentration (100.90 ± 8.11 mg/mL), while the lowest concentration was in the Camosciata breed (74.75 ± 20.16 mg/mL). Finally, the highest lactoferrin concentration was in Frisa (1781.3 ± 892.6 µg/mL) and the lowest in Camosciata and Lariana (763.1 ± 357.9 and 1148.0 ± 858.6 µg/mL, respectively; p < 0.05). Differences between Camosciata and local breeds could be due to the different farming systems, in addition to the genetic characteristics. The higher quality of colostrum produced by some local goats could be an adaptive characteristic that helps the growth and survival of the kids.
RESUMO
Sheep and goat extensive production systems are very important in the context of global food security and the use of rangelands that have no alternative agricultural use. In such systems, there are enormous challenges to address. These include, for instance, classical production issues, such as nutrition or reproduction, as well as carbon-efficient systems within the climate-change context. An adequate response to these issues is determinant to economic and environmental sustainability. The answers to such problems need to combine efficiently not only the classical production aspects, but also the increasingly important health, welfare, and environmental aspects in an integrated fashion. The purpose of the study was to review the application of technological developments, in addition to remote-sensing in tandem with other state-of-the-art techniques that could be used within the framework of extensive production systems of sheep and goats and their impact on nutrition, production, and ultimately, the welfare of these species. In addition to precision livestock farming (PLF), these include other relevant technologies, namely omics and other areas of relevance in small-ruminant extensive production: heat stress, colostrum intake, passive immunity, newborn survival, biomarkers of metabolic disease diagnosis, and parasite resistance breeding. This work shows the substantial, dynamic nature of the scientific community to contribute to solutions that make extensive production systems of sheep and goats more sustainable, efficient, and aligned with current concerns with the environment and welfare.
RESUMO
INTRODUCTION: Congenital cytomegalovirus (CMV) infection is one of the most common during pregnancy. The infection, particularly in the first trimester, is associated with important sequelae in up to half of the children. Valaciclovir and immunoglobulin have been tested separately for the treatment of fetal CMV infection with relative success. Nevertheless, there is no experience with the simultaneous use of both therapies. METHODS: combination therapy (oral valaciclovir 2 g/6h until the end of pregnancy and intravenous hyperimmune gamma globulin 200 UI/kg) was offered to pregnant women with CMV infection acquired during pregnancy and viral load (VL) in amniotic fluid above 105 copies/ml and/or brain injuries in the ultrasonography. Additional immunoglobulin monthly doses were used in case of ultrasonography or MRI evidence of persistent fetal involvement. Neurological and hearing evaluations of infants were performed at birth and every 3 months during follow-up. RESULTS: 15 pregnant women were enrolled: primary infection, 14, non-primary infection, 1; first trimester, 11, second trimester, 4. Mean gestational age at the start of combination treatment were 23.2 weeks and 29.3 weeks, depending on the infection being diagnosed in the first or the second trimester, respectively. Median VL of CMV-DNA in amniotic fluid was 62.5 × 105 copies/ml. Intrauterine progression of fetal brain lesions was only observed in two cases in which the dose of CMV-HIG was repeated, slowing their progression. Although the treatment has failed to reverse ultrasound fetal lesions, only 3 children were born with hearing impairment and their psychomotor development was consistent with chronological age in all patients but one. Combination therapy was not associated with adverse effects in either the mothers or the fetuses. CONCLUSION: Combination therapy with immunoglobulin and valaciclovir may be a useful alternative in CMV fetal infection, particularly if changes in cerebral echography or high VL in the amniotic fluid are present.

Ancylostoma caninum is a zoonotic nematode which is able to affect animals and humans. Diagnosis in the definitive host and environmental detection are key to prevent its dissemination and achieve control. Herein, a new coprological LAMP method for the detection of A. caninum (Copro-LAMPAc) DNA was developed. DNA extraction was performed using a low-cost method and a fragment of the cox-1 gene was used for primer design. The analytical sensitivity, evaluated with serial dilutions of genomic DNA from A. caninum adult worms, was 100 fg. A specificity of 100% was obtained using genomic DNA from the host and other pathogens. The Copro-LAMPAc was evaluated using environmental canine fecal samples. When compared with gold standard optical microscopy in epidemiological studies, it proved to be more sensitive. This new LAMP assay can provide an alternative protocol for screening and identification of A. caninum for epidemiological studies in endemic areas.
RESUMO
Background: Family Integrated Care (FICare) integrates parents in the direct care of their child while the healthcare personnel act as teachers and guides. To this date, most reports on the feasibility of this model refer to stable preterm infants admitted to Neonatal Intensive Care Units (NICUs). Objectives: To scale up and adapt FICare to make it suitable in level IIIC NICUs, which care for extreme prematurity and other complex medical or surgical neonatal conditions. Materials and Methods: Step 1 was the creation of the FICare implementation team (FICare-IT) and baseline analysis of current procedures for critical care to identify needs, wishes, and requirements; we aimed for protocol elaboration tailored to our cultural, architectural, and clinical context (March 2017 to April 2018). Step 2 as a dissemination strategy by FICare-IT acting as primary trainers and mentors to ensure the education of 90% of nursing staff (May 2018 to July 2018). Step 3 involved piloting and evaluation with the aim to refine the procedure (July 2018 to December 2020). Results: A rigorous but flexible protocol was edited. The FICare educational manual included two curricula: for healthcare professionals/staff (Training the trainers) and for families (Education of caregivers), the latter being categorized in two intervention levels (basic and advanced), depending on the infant care needs and parent's decision. In total, 76 families and 91 infants (74.7% preterm; 18.7% complex surgery; 6.6% others) were enrolled in the pilot. No differences in acceptance rate (overall 86.4%) or in the number of infant-family dyads in the program per month were observed when considering the pre- and post-Covid-19 pandemic periods. All families, except for one who dropped out of the program, completed the agreed individualized training. Mothers spent more time in NICU than fathers (p < 0.05); uninterrupted time spent by mothers in NICU was longer during the pre-pandemic period (p < 0.01). Observed time to reach proficiency by task was within the expected time in 70% of the program contents. The parents revealed educational manuals, workshops, and cot-side teaching sessions as essential for their training, and 100% said they would accept entry into the FICare program again. Conclusions: The principles of the FICare model are suitable for all levels of care in NICUs. Leadership and continuous evaluation/refinement of implementation procedures are essential components to achieve the objectives.
RESUMO
RESUMEN En el Paraguay como país bilingüe y contexto histórico característico siempre se ha considerado un desafío llegar a la población guaraní parlante, especialmente de sectores más vulnerables, mediante el uso de herramientas que acorten la brecha de la barrera idiomática en los servicios de atención en general. Realizando la traducción del cuestionario de diagnóstico de epilepsia dirigido a su uso en atención primaria, se pretende acercar al profesional médico un elemento útil en la práctica clínica que además aporte datos de valor diagnóstico y guía de tratamiento. En este trabajo se realizó la validación del cuestionario, originalmente concebido en español, distinguiendo algunos aspectos idiomáticos que aportan riqueza a la historia clínica en epilepsia y definen el aspecto terapéutico brindando al profesional médico un material de uso práctico y fácil de aplicabilidad en la práctica clínica diaria.
ABSTRACT In Paraguay, as a bilingual country and its characteristic historical context, to reach the speaking Guaraní population has always been considered a challenge, especially in the most vulnerable sectors, through the use of tools that reduce the gap of the language barrier in health care services in general. By translating the epilepsy diagnosis questionnaire aimed at its use in primary care, it was expected to bring closer to the medical professional a useful element in clinical practice that also provided data of diagnostic value and treatment guidelines. In this work, the validation of the questionnaire, originally conceived in Spanish, was carried out, distinguishing some idiomatic aspects that contribute richness to the clinical history in epilepsy and define the therapeutic aspect, providing the medical professional with a material of practical use and easy to apply in daily clinical practice.
RESUMO
Cystic echinococcosis (CE) is a parasitic zoonosis caused by Echinococcus granulosus. The control program of CE of Rio Negro province, Argentina, involves annual surveillance using ultrasound (US) screening in school children, and five-year cross-sectional surveys to detect livestock farms with parasitized dogs by coproELISA with confirmation tests (Western Blot or PCR). Control program is based on deworming of dogs with praziquantel and the aim is to identify areas at risk of Cystic echinococcosis transmission to humans, using all available data sources. The information was spatially distributed in 13 program areas and, at a smaller geographical scale, in 80 Primary Health Care Centers. CoproELISA surveys involved three randomized sampling periods (2003-05, 2009-10, 2017-18), with 1790 canine fecal samples. The US surveys were conducted in 2003-08, 2009-16 and 2017-18 in 34,515 children. Heat maps were created at the smallest geographic scale with QGIS 3.4.6. For the consecutive sampling periods, prevalence of positive canine fecal samples from livestock farms were 14.7, 12.1 and 7.8%, respectively, and children prevalence was 0.4, 0.2 and 0.1%, respectively. The study has been developed on a scale according to which the temporal-spatial distribution of CE allows to adjust control strategies in those areas of potential transmission of the zoonosis to humans.

[ABSTRACT]. Objective. To compare the performance of polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) tests for diagnosing Echinococcus granulosus in dog feces among national reference laboratories in Argentina, Chile, Peru, and Uruguay. Methods. National laboratories affiliated with the Ministry of Health/Agriculture of each country exchanged panels of 10 positive/negative samples obtained from their regular national surveillance programs in November 2015 – November 2016. All laboratories applied PCR; two also applied ELISA techniques. Sensitivity and specificity were determined for each laboratory and concordance of results among the laboratories was evaluated by Cohen Kappa coefficient. Results. Poor concordance (3 of 10 paired comparisons had values of Kappa > 0.4), low sensitivity and specificity across all laboratories, and poor performance of both techniques in detecting E. granulosus in canine feces was demonstrated in this study. An ex-post comparison of the laboratories’ test protocols showed substantial heterogeneity that could partially explain poor concordance of results. Conclusion. The results underscore the heterogeneity of canine echinococcosis diagnosis across the region and indicate possible sources of variability. Efforts to standardize canine echinococcosis testing must be included in the plan of action for the Regional Initiative for the Control of Cystic Echinococcosis. Future comparisons with fecal samples of known parasite load are needed.
[RESUMEN]. Objetivo. Comparar el rendimiento de los ensayos de la reacción en cadena de la polimerasa y el enzimoinmunoanálisis de adsorción en fase sólida (o ELISA, por su sigla en inglés) para diagnosticar Echinococcus granulosus en heces caninas en los laboratorios de referencia nacionales de Argentina, Chile, Perú y Uruguay. Métodos. Los laboratorios nacionales, afiliados a los ministerios de salud y agricultura y ganadería de cada país, intercambiaron paneles de diez muestras positivas y negativas obtenidas de sus respectivos programas nacionales de vigilancia desde el mes de noviembre del año 2015 hasta el mismo mes del año siguiente. Todos los laboratorios emplearon la reacción en cadena de la polimerasa y dos emplearon también técnicas de ensayo inmunoenzimático (ELISA). Se determinó la sensibilidad y la especificidad de cada laboratorio y se evaluó la concordancia entre los resultados de los laboratorios mediante el coeficiente kappa de Cohen. Resultados. Este estudio descubrió una escasa concordancia (3 de 10 comparaciones de pares obtuvieron valores de kappa > 0,4), una sensibilidad y especificidad bajas en todos los laboratorios y un rendimiento deficiente de ambas técnicas de diagnóstico de Echinococcus granulosus en heces caninas. La comparación ex post de los protocolos de ensayo de los laboratorios mostró una heterogeneidad sustancial que podría explicar parcialmente la escasa concordancia de los resultados. Conclusiones. Los resultados subrayan la heterogeneidad del diagnóstico de equinococosis canina en toda la región e indican posibles fuentes de esta variabilidad. Deben incluirse medidas para estandarizar la prueba de equinococosis canina en el plan de acción de la Iniciativa Sudamericana para el Control de la Equinococosis Quística. En el futuro serán necesarias comparaciones adicionales con muestras fecales con una carga de parásitos conocida.
[RESUMO]. Objetivo. Comparar o desempenho dos métodos de reação em cadeia da polimerase (PCR) e ensaio imunoenzimático (ELISA) no diagnóstico de infecção pelo Echinococcus granulosus em fezes de cães entre laboratórios de referência nacional na Argentina, Chile, Peru e Uruguai. Métodos. Laboratórios nacionais conveniados ao Ministério da Saúde/Agricultura de cada país participante intercambiaram grupos de 10 amostras positivas/negativas coletadas rotineiramente pelos programas nacionais de vigilância no período de novembro de 2015 a novembro de 2016. Todos os laboratórios empregaram o método de PCR e dois empregaram também o método de ELISA. A sensibilidade e a especificidade dos métodos foram determinadas em cada laboratório, e a concordância dos resultados entre os laboratórios participantes foi avaliada com o coeficiente kappa de Cohen. Resultados. Observou-se fraca concordância (3 de 10 comparações pareadas com kappa >0,4), baixa sensibilidade e especificidade e fraco desempenho de ambos os métodos na identificação do E. granulosus em amostras fecais de cães nos laboratórios participantes do estudo. Uma comparação retroativa revelou considerável heterogeneidade dos protocolos de análise laboratorial, o que poderia em parte explicar a fraca concordância entre os resultados. Conclusões. Os resultados deste estudo apontam para a falta de uniformidade no diagnóstico de equinococose canina em toda a Região e indicam possíveis causas para variabilidade. A padronização da análise laboratorial da equinococose canina deve constar do plano de ação para a Iniciativa Regional para Controle da Hidatidose. Outras comparações de amostras fecais de parasitas conhecidos devem ser realizadas.

Objetivos: Caracterizar la enfermedad por reflujo faringolaríngeo en pacientes de edad avanzada y ancianos. Métodos: Estudio retrospectivo de pacientes mayores de 60 años, con sintomatología sugestiva de enfermedad por reflujo faringolaríngeo, vistos entre 2005 y 2014 en el Departamento de Otorrinolaringología de un hospital universitario. Se seleccionaron 85 pacientes (54 mujeres y 31 hombres) sometidos a una pH-metría de 24 h con doble sensor ("gold standard" en el diagnóstico del reflujo). Se calculó el índice de masa corporal. Se revisó la información clínica y evaluaron las pH-metrías según los criterios de DeMeester y Johnson. Se revisó el cuestionario «Reflux Symptoms Index» (RSI), considerado patológico cuando fue ≥13. Se evaluaron los hallazgos endoscópicos faringolaríngeos del "Reflux Finding Score" (RFS), considerado patológico cuando fue ≥7. Resultados: La edad media fue 67 años. En 70 pacientes (82%) la pH-metría fue patológica. El índice de masa corporal fue patológico en 50 pacientes (59%), de los que casi el 90% tenían pH-metría patológica. El RSI medio fue 9,8, con resultados anormales en 24 pacientes (28%). En 20 pacientes (23%) con RSI anormal tenían una pH-metría positiva. El hallazgo endoscópico más común (90%) fue la hipertrofia de comisura posterior. El RFS medio fue 9,07, con resultados anormales en 69 pacientes (70%). En 61 pacientes (70%) con RFS anormal tenían una pH-metría patológica. Solo 18 pacientes con RSI y RFS patológicos tenían una pH-metría patológica. Conclusiones: En pacientes mayores, los valores patológicos de índice de masa corporal se asocian altamente con pH-metrías patológicas. El RSI es un indicador de poco valor, mientras que el RFS es de valor moderado
Objectives: To characterize laryngo-pharyngeal reflux (LPR) in patients over 60 years of age. Methods: Retrospective review of patients over 60 years of age with symptoms suspicious of LPR, seen from 2005 to 2014 at an ENT Department of an academic hospital. Eighty-five consecutive patients (54 females, 31 males) who had completed a dual-sensor 24-hour pH-metry were included (considered "gold-standard" in LPR diagnosis). Body mass index, and reflux information and interventions were revised. pH-metries were evaluated according to DeMeester & Johnson's criteria. Symptoms were assessed according to the Reflux Symptom Index (RSI) and classified as abnormal if score was ≥ 13. A naso-fibro-laryngoscopy enabled findings to be documented according to the Reflux Finding Score (RFS), and they were classified as abnormal if the score was ≥ 7. Results: The patients mean age was 67 years. A positive pH-metry was present in 70 patients (82.5%). Fifty patients (59%) had abnormal body mass index, and almost 90% of them had an abnormal pH-metry. Mean RSI score was 9.8, with abnormal results in 24 patients (28%). Only 20 patients (23%) with abnormal RSI had a positive pH-metry. Posterior commissure hypertrophy was the most common finding (90% of patients). Mean RFS score was 9.07, with abnormal results in 69 patients (81%). Sixty-one patients (70%) with abnormal RFS had a positive pH-metry. Only 18 patients (20%) had coincidental abnormal pH-metry, RSI, and RFS. Conclusions: In ageing patients, abnormal body mass index is strongly associated with abnormal pH-metry. RSI is a weak indicator of LPR, whereas RFS has a moderate value

Background: Mechanistic target of rapamycin (mTOR) inhibitors are being used off-label showing promising results in patients with vascular anomalies. Children with lymphatic malformations (LMs) involving the airway benefit from sirolimus therapy soon after birth, reducing the need of tracheostomy. Available information about efficacy and side effects in neonates remains poor. We present seven newborns with severe head and neck LM showing response to sirolimus with no significant toxicity. Methods and Results: We performed a retrospective review of neonates with head and neck LM who received sirolimus between January 2014 and May 2018 with upper airway involvement needing ventilatory support. We analyzed type of LM, involved anatomical area, symptoms and response to sirolimus, including dosage, blood levels, response, side effects, and complications. Seven neonates received primary treatment with sirolimus in the context of cervical LM. Sirolimus was started at the recommended dose of 0.8 mg/m2/12 h and adjusted to maintain blood levels between 4 and 12 ng/mL. Median follow-up was 32 months (4-43) with a median treatment duration of 12 months (3-43). One patient had complete resolution of the malformation, one had complete resolution of symptoms, and five had partial resolution of the malformation with significant improvement in their respiratory conditions. Two patients required additional subtotal surgical resection and one tracheostomy. Four patients remain under treatment. Toxicity was not observed. Conclusions: Sirolimus is a safe drug in neonates and can be considered the first therapeutical option in newborns at high risk of respiratory failure before sclerosis or surgery. Close follow-up is mandatory to identify side effects at long-term use.

Las enteroparasitosis poseen una distribución universal, tanto en zonas rurales como urbanas, y afectan principalmente a la población infantil, para la cual representan un problema muy frecuente en salud pública. El daño ocasionado en el aparato digestivo puede causar en los niños retardo de la maduración, alteraciones del estado nutricional y bajo rendimiento escolar. Respecto del diagnóstico etiológico, la aplicación de técnicas de concentración a las muestras fecales, previa a la observación microscópica, mejora la sensibilidad, debido a que la excreción de elementos parasitarios puede, en ocasiones, ser escasa o intermitente. Los métodos de sedimentación como el de Telemann son los más empleados en el diagnóstico parasitológico, aunque poseen la desventaja del uso de éter etílico, compuesto moderadamente tóxico. Con el objetivo de evaluar la eficiencia global diagnóstica del equipo Mini Parasep® SF, y su confiabilidad durante su empleo, se procesaron 148 muestras de materia fecal por los métodos de Telemann modificado y Mini Parasep® SF. Una vez aplicados los métodos convencionales, el diagnóstico microscópico fue realizado por dos observadores a través de una investigación a doble ciego. Del total de muestras analizadas (n=148) y desagregando aquellas positivas en resultados individuales cuando éstas tenían más de un agente etiológico (ntotal=234), el 65,8% (154/234) fueron positivas y el 34,2% (80/234) negativas. A partir de observaciones aleatorizadas y repetidas se estimó la acordancia de resultados intraoperador en 90,3% y entre operadores en 90,5%. A partir de las observaciones independientes, se obtuvo un índice de concordancia entre operadores, Kappa=0,83 (muy bueno). No se observaron diferencias estadísticamente significativas entre los valores de sensibilidad (S) y especificidad (E) estimados para cada uno de los observadores (O) con un IC95%, (S/O1) 94,8%; (S/O2) 97,4%; y (E/O1) 92,5%; (E/O2) 95,0%. La eficiencia global del test según operador fue 94,02% y 96,58 respectivamente. Los resultados obtenidos sugieren que ambas técnicas podrían ser empleadas para concentrar muestras fecales para investigar enteroparásitos. El método Mini Parasep® SF demostró ser sencillo, rápido y efectivo, y no necesitó éter como solvente orgánico, y por su eficiencia global, podría ser útil en aquellos laboratorios imposibilitados de utilizar las técnicas convencionales.
Enteroparasitoses have a universal distribution, both in rural and urban areas, and they affect mainly the infant population, for which reason they represent a very frequent problem in public health. The damage caused in the digestive system can give rise to retardation in children, changes in nutritional status and poor school performance. With respect to the etiological diagnosis, the application of concentration techniques to fecal samples, prior to microscopic observation, improves sensitivity, taking into account that the excretion of parasitic elements can sometimes be scarce or intermittent. Sedimentation methods such as Telemann, are the most widely used in the parasitological diagnosis, although they have the disadvantage of the use of ethyl ether, a moderately toxic compound. In order to evaluate the overall diagnostic efficiency of the Mini Parasep® SF kit, and its reliability during its use, 148 stool samples were processed by modified Telemann and Mini Parasep® SF methods. Once the conventional methods were applied, the microscopic diagnosis was made by two observers through double-blind research. Of the total samples analyzed (n=148) and disaggregating positive ones in individual results when they had more than one etiological agent (n total=234), 65.8% (154/234) were positive and 34.2% (80/234) negative. Based on randomized and repeated observations, the accordance of intraoperator results was estimated at 90.3% and between operators at 90.5%. From the independent observations, a concordance index between operators was obtained, Kappa=0.83 (very good). No statistically significant differences were observed between the values of sensitivity (S) and specificity (E) estimated for each of the observers (O) with an IC95%, (S/O1) 94.8%; (S/O2) 97.4%; and (E/O1) 92.5%; (E/O2) 95.0%. The overall efficiency of the test according to the operator was 94.02% and 96.58 respectively. The results obtained suggest that both techniques could be used to concentrate fecal samples to investigate enteroparasites. The Mini Parasep® SF method proved to be simple, fast and effective, and did not need ether as an organic solvent. Because of its overall efficiency, it could be useful in laboratories that are unable to use conventional techniques.
As enteroparasitoses têm uma distribuição universal, tanto em áreas rurais como urbanas, e afetam principalmente a população infantil, para as quais representam um problema muito frequente na saúde pública. Os danos causados no sistema digestivo podem causar retardamento em crianças, alterações no estado nutricional e baixo desempenho escolar. No diagnóstico etiológico, as técnicas de concentração de aplicação para amostras fecais, antes da observação microscópica, melhoram a sensibilidade, uma vez que a excreção de elementos parasitas pode por vezes ser pouco ou intermitente. Métodos de sedimentação, como Telemann, são os mais utilizados no diagnóstico parasitológico, embora tenham a desvantagem do uso de éter etílico, um composto moderadamente tóxico. Para avaliar a eficiência diagnóstica geral do kit Mini Parasep® SF e sua confiabilidade durante o uso, 148 amostras de fezes foram processadas pelos métodos modificado Telemann e Mini Parasep® SF. Uma vez que os métodos convencionais foram aplicados, o diagnóstico microscópico foi feito por dois observadores através de pesquisa duplo-cego. De todas as amostras testadas (n=148) e desagregando esses resultados positivos quando estes indivíduo tinha mais do que um agente etiológico (N total=234), 65,8% (154/234) foram positivos, e 34,2% (80/234) negativos. Com base em observações aleatórias e repetidas, a acordância dos resultados intraoperatórios foi estimada em 90,3% e entre os operadores em 90,5%. A partir das observações independentes, obteve-se um índice de concordância entre os operadores, Kappa=0,83 (muito bom). Não foram observadas diferenças estatisticamente significativas entre os valores de sensibilidade (S) e especificidade (E) estimados para cada um dos observadores (O) com IC95%, (S/O1) 94,8%; (S/O2) 97,4%; e (E/O1) 92,5%; (E/O2) 95,0%. A eficiência global do teste de acordo com o operador foi de 94,02% e 96,58, respectivamente. Os resultados obtidos sugerem que ambas as técnicas podem ser usadas para concentrar amostras fecais para investigar enteroparasitas. O método Mini Parasep® SF mostrou-se simples, rápido e efetivo, não necessitando de éter como solvente orgânico e, devido à sua eficiência global, pode ser útil em laboratórios incapazes de utilizar técnicas convencionais.

Evaluation of traumatic peripheral nerve injuries has classically been based on clinical and electrophysiologic criteria. US and MRI have been widely used for morphologic assessment of nerve injury sites and concomitant lesions. In the past few years, morphologic MR neurography has significantly increased its clinical applications on the basis of three-dimensional or two-dimensional images with and without fat-suppression techniques. However, these sequences have a major drawback: absence of pathophysiologic information about functional integrity or axonal flow of peripheral nerves. In this scenario, functional MRI techniques such as diffusion-weighted imaging (DWI) or diffusion tensor imaging (DTI) can be used as a complementary tool in initial evaluation of peripheral nerve trauma or in assessment of trauma undergoing surgical repair. These approaches provide not only morphologic but also functional information about extent and degree of nerve impairment. Functional MR neurography can also be applied to selection, planning, and monitoring of surgical procedures that can be performed after traumatic peripheral nerve injuries, such as neurorrhaphy, nerve graft, or neurolysis, as it provides surgeons with valuable information about the functional status of the nerves involved and axonal flow integrity. The physical basis of DWI and DTI and the technical adjustments required for their appropriate performance for peripheral nerve evaluation are reviewed. Also, the clinical value of DWI and DTI in assessment of peripheral nerve trauma is discussed, enhancing their potential impact on selection, planning, and monitoring of surgical procedures employed for peripheral nerve repair. Online supplemental material is available for this article. ©RSNA, 2019.

Cystic echinococcosis (CE) is endemic in the Rio Negro province of Argentina. After 30 years of control using praziquantel in dogs the transmission rate to humans and sheep has decreased significantly, however transmission persists. The objective of the study was to assess the inclusion of the EG95 for sheep in the control program and to determine the vaccine's operative feasibility in field conditions. An intervention study was defined in Rio Negro Province in Argentina comprising, in total, an area of 5820 Km2. Lambs received two vaccinations with the EG95 vaccine followed by a single booster injection when the animals were 1-1.5 years of age. Vaccination of lambs born into one trial site was introduced and continued for 8 years. Evidence for Echinococcus granulosus transmission was monitored before and after vaccination by coproantigen ELISA in faecal samples of dog, purgation of dogs to detect E. granulosus worms, necropsy on adult sheep and by ultrasound screening in children of 6-14 years old. 29,323 doses of vaccine were applied between 2009 and 2017, which a vaccination coverage of 80.1%/85.7% (57.3% average for fully vaccinated). Before the introduction of the vaccine 56.3% of the 6-year-old sheep were infected with E. granulosus at necropsy and 84.2% of the farms had infected sheep; 4.3% of the dogs were positive for E. granulosus infection using the arecoline test, and with coproELISA 9.6% of dog fecal samples were positive and 20.3% of the farms had infected dog.After the vaccine was introduced, 21.6% of sheep older than 6 years were found to be infected at necropsy and 20.2% of the farms were found to be infected; in dogs, 4.5% were found positive for E. granulosus using arecoline purgation and with coproELISA 3.7% of samples were positive, with 8.9% of farms having a positive dog. In 2016 only one case of E. granulosus infection was diagnosed by US screening in a 6-14 years old child. Included in the analysis are discussions of difficulties experienced in the field which affected correct vaccine administration as well as social features and practices that may impact on echinococcosis control and the EG95 vaccination program in Rio Negro. Vaccination of sheep with the EG95 vaccine provides a valuable new tool which improves the effectiveness of CE control activities. Vaccination was effective even in a difficult, remote environment where only approximately half the lambs born into the communities were fully vaccinated.

OBJECTIVES: To characterize laryngo-pharyngeal reflux (LPR) in patients over 60 years of age. METHODS: Retrospective review of patients over 60 years of age with symptoms suspicious of LPR, seen from 2005 to 2014 at an ENT Department of an academic hospital. Eighty-five consecutive patients (54 females, 31 males) who had completed a dual-sensor 24-hour pH-metry were included (considered "gold-standard" in LPR diagnosis). Body mass index, and reflux information and interventions were revised. pH-metries were evaluated according to DeMeester & Johnson's criteria. Symptoms were assessed according to the Reflux Symptom Index (RSI) and classified as abnormal if score was ≥13. A naso-fibro-laryngoscopy enabled findings to be documented according to the Reflux Finding Score (RFS), and they were classified as abnormal if the score was ≥7. RESULTS: The patients' mean age was 67 years. A positive pH-metry was present in 70 patients (82.5%). Fifty patients (59%) had abnormal body mass index, and almost 90% of them had an abnormal pH-metry. Mean RSI score was 9.8, with abnormal results in 24 patients (28%). Only 20 patients (23%) with abnormal RSI had a positive pH-metry. Posterior commissure hypertrophy was the most common finding (90% of patients). Mean RFS score was 9.07, with abnormal results in 69 patients (81%). Sixty-one patients (70%) with abnormal RFS had a positive pH-metry. Only 18 patients (20%) had coincidental abnormal pH-metry, RSI, and RFS. CONCLUSIONS: In ageing patients, abnormal body mass index is strongly associated with abnormal pH-metry. RSI is a weak indicator of LPR, whereas RFS has a moderate value.

OBJECTIVE: The aim of this study is to evaluate the use and safety of a sedation protocol with sevoflurane for short painful procedures in newborns. STUDY DESIGN: This was a prospective and observational study conducted in a tertiary neonatal intensive care unit. Sevoflurane was recommended in patients undergoing an invasive procedure of short length, especially in those with spontaneous breathing or without venous access. Its safety and efficacy was assessed by continuous monitoring of respiratory and hemodynamic variables and clinical data recording. RESULTS: Sevoflurane was used for 39 procedures, the main indications were: intravitreal bevacizumab injection (12), central venous catheterization (11), and biopsy (6). The median administration length was 14 minutes (range: 5-65 minutes). The median minimum dose was 1.5% (range: 1-3%). The median maximum dose was 2.5% (range: 1-6%). An effective control of nociceptive manifestations was achieved in 35 cases (90%). No major adverse effects were noticed. Main adverse effects were hypotension (8), desaturation (4), and apnea (3). All of them were solved by decreasing (14) or discontinuing (1) the administration of sevoflurane. CONCLUSION: Sevoflurane is relatively easy to use and provides an optimal control of pain-related symptoms. Its prescription should be individualized and more long-term follow-up data are needed.

OBJECTIVE: To compare the performance of polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) tests for diagnosing Echinococcus granulosus in dog feces among national reference laboratories in Argentina, Chile, Peru, and Uruguay. METHODS: National laboratories affiliated with the Ministry of Health/Agriculture of each country exchanged panels of 10 positive/negative samples obtained from their regular national surveillance programs in November 2015 - November 2016. All laboratories applied PCR; two also applied ELISA techniques. Sensitivity and specificity were determined for each laboratory and concordance of results among the laboratories was evaluated by Cohen Kappa coefficient. RESULTS: Poor concordance (3 of 10 paired comparisons had values of Kappa > 0.4), low sensitivity and specificity across all laboratories, and poor performance of both techniques in detecting E. granulosus in canine feces was demonstrated in this study. An ex-post comparison of the laboratories' test protocols showed substantial heterogeneity that could partially explain poor concordance of results. CONCLUSION: The results underscore the heterogeneity of canine echinococcosis diagnosis across the region and indicate possible sources of variability. Efforts to standardize canine echinococcosis testing must be included in the plan of action for the Regional Initiative for the Control of Cystic Echinococcosis. Future comparisons with fecal samples of known parasite load are needed.
