RESUMO
The giant anteater (Myrmecophaga tridactyla) is classified as vulnerable to extinction. Here, we report the occurrence of ancylostomiasis in a young male Myrmecophaga tridactyla. The animal was raised from a puppy in captivity with management directed toward rehabilitation and monitored soft release. Five months after release, significant weight loss was noted in the individual, who was captured for examinations, with detection of Ancylostoma sp. in coproparasitological analysis. Although common in domestic carnivores, this is the first report of hookworm disease in free-ranging giant anteaters. Due to the stress factor arising from adapting to the challenges in the new environment, long-term post-release monitoring of animals undergoing rehabilitation is extremely important to increase the chance of survival of individuals. The giant anteater was released after treatment with vermifuge composed of fenbendazole, pyrantel pamoate, and praziquantel.
O tamanduá-bandeira (Myrmecophaga tridactyla) está classificado como vulnerável quanto ao risco de extinção. O objetivo deste trabalho é reportar a ocorrência de ancilostomíase em um macho jovem da espécie. Trata-se de um indivíduo que foi criado desde filhote em cativeiro, com manejo direcionado para a reabilitação e a soltura branda. Durante o monitoramento, cinco meses após a soltura, observou-se que o animal havia perdido peso, por isso ele foi capturado para avaliação médica veterinária, e constatou-se parasitismo por Ancylostoma sp. no exame coproparasitológico. Apesar de apresentar ocorrência comum em carnívoros domésticos, este é o primeiro relato de ancilostomíase em tamanduá-bandeira em vida livre. Devido ao estresse de adaptação, juntamente com os desafios do novo ambiente, a monitoração pós-soltura a longo prazo é de extrema importância para aumentar a chance de sobrevivência dos animais. O indivíduo foi solto após tratamento com vermifugação com a associação de fembendazol, pamoato de pirantel e praziquantel.

Resumen Introducción: La rehabilitación del piso pélvico es frecuentemente indicada a los pacientes con incontinencia fecal. Su efectividad a corto plazo ha sido demostrada. Sin embargo, sus resultados en el largo plazo son controversiales. Objetivo: Nuestro objetivo es evaluar los resultados funcionales y calidad de vida a largo plazo de los pacientes con incontinencia fecal tratados mediante rehabilitación del piso pélvico. Materiales y Método: Estudio cuasi-experimental. Se incluyeron los pacientes con incontinencia fecal tratados mediante rehabilitación del piso pélvico entre 2007-2014 en nuestro centro, sin necesidad de cirugía. Se midió el puntaje funcional de Wexner y de calidad de vida (FIQLS) antes (T1) y después del tratamiento (T2). Se realizó encuesta vía correo electrónico para obtener dichos puntajes entre 3-10 años posterior al tratamiento (T3). Resultados: De 215 pacientes, 182 cumplían criterios de inclusión. 96 (52,8%) de ellos respondieron la encuesta en T3. La mediana de seguimiento fue de 4,5 (3-10) años. La edad promedio al tiempo del estudio fue de 60,8 ±13,1 años. 88,4% fueron mujeres. La mediana del puntaje funcional fue 16 (6-20) en T1 y 7 (0-18) en T2, p = 0,000. La calidad de vida mejoró significativamente en sus 4 dimensiones entre T1 y T2. En T3, ambos puntajes presentaron mejores promedios que en T1, p = 0,000. No hubo asociación entre el tiempo de seguimiento y el resultado funcional en T3. Conclusión: Los pacientes con incontinencia fecal tratados mediante rehabilitación del piso pélvico mejoran significativamente su funcionalidad y calidad de vida. El beneficio disminuye en el tiempo, pero persiste mejor que previo al tratamiento.
Introduction: Pelvic floor rehabilitation is often indicated as first-line therapy for patients with fecal incontinence. Its short-term effectiveness has been demonstrated in these patients. However, long-term results are controversial. Aim: Our objective is to evalúate long-term functionality and quality of life in patients with fecal incontinence treated with pelvic floor rehabilitation. Materials and Method: Quasi- experimental study conducted at a single tertiary care center. We included patients with fecal incontinence treated by pelvic floor rehabilitation at our center between 2007-2014 who did not require surgery. Wexner functional score and quality of life using FIQLS were measured pre (T1) and post-treatment (T2). Poste - riorly, an-e-mail survey was conducted to retrieve scores three to 10 years after treatment (T3). Results: Of the 215 patients, 182 met the inclusion criteria. 96 (52.8%) patients responded at T3 and were therefore included. The median follow-up period was of 4.5 years (3-10). The mean age at the time of the study was 60.8 ± 13.1 years and 88.4% were women. The median Wexner score was 16 (6-20) in T1 and 7 (0-18) in T2, (p = 0.000). Quality of life improved significantly in its four dimensions when comparing T1 and T2. In T3, Wexner and the quality of life scores were significantly lower than T2. However, in T3, both scales had better means than T1, (p = 0.000). There was no association between the follow-up time and the functional result in T3. Conclusions: Patients with fecal incontinence treated by pelvic floor rehabilitation improve their functionality and quality of life significantly. This benefit decreases over time but remains above its baseline.

La hipoacusia unilateral (HUL) definida como la pérdida auditiva de cualquier grado en un solo oído tiene prevalencias en edad escolar de 3% a 6%. La etiología es desconocida en la mayoría de los casos, pero destacan las anormalidades anatómicas severas a diferencia de las hipoacusias bilaterales, lo que le otorga importancia al estudio de imágenes. También se recomienda realizar evaluación oftalmológica. El impacto de la HUL se observa en la localización sonora, reconocimiento del habla, desarrollo del lenguaje, desempeño social y conducta, pero por sobre todo en el rendimiento académico. En este sentido es relevante mencionar que además de existir mayor probabilidad de repitencia de curso, es necesario mayor apoyo educacional individualizado para evitar dicha repitencia o lograr mismo éxito académico que un normoyente. En relación al diagnóstico aún faltan normas o protocolos, siendo éste un desafío en las zonas donde no hay screening universal. Se discute la importancia de las encuestas para realizar evaluaciones y seguimiento en estos casos. Finalmente se abordan las estrategias de intervención disponibles, además de un plan individualizado considerando al niño, su familia y sus expectativas, particularmente se discuten las características o factores a tomar en cuenta en el momento de la adaptación, para así lograr un tratamiento tendiente al éxito.
Unilateral hearing loss (UHL) defined as hearing loss of any degree in only one ear has a school-age prevalence of 3% to 6%. The etiology is unknown in most cases, but severe anatomical abnormalities stand out as opposed to bilateral hearing loss, which gives importance to the study of images. Ophthalmological evaluation is also recommended. The impact of UHL is observed in sound localization, speech recognition, language development, social performance and behavior, but above all in academic performance. In this sense, it is relevant to mention that in addition to having a higher probability of repeating the course, it is necessary to have more individualized educational support to avoid this repetition or achieve the same academic success as a normal listener. Regarding the diagnosis, there are still missing norms or protocols, this being a challenge in areas where there is no universal screening. The importance of surveys to carry out evaluations and follow-up in these cases is discussed. Finally, the available intervention strategies are discussed, in addition to an individualized plan considering the child, his family and his expectations, particularly, the factors to be taken into account at the time of adaptation, in order to achieve a success treatment.

Half of cases of hepatitis B around the world are produced from vertical transmission; and 90% of them can evolve to chronic hepatitis and their long term complications. Postpartum immunoprophylaxis (immunoglobulin and vaccine) is the most effective preventive measure. However, despite this prophylaxis, vertical transmission is possible if the mother presents a high viral load or e-antigen. This risk can be reduced only if screening during pregnancy and treatment if needed, are incorporated. In 2019, vaccination for hepatitis B in newborn was incorporated in Chile, but not yet prenatal screening, unlike developed countries. Chile has experienced a growth in immigration from Latin America and Caribbean, some countries with high endemicity included. Prenatal screening in Chile should be promptly incorporated.

Resumen La transmisión vertical de hepatitis B es responsable de 50% de las infecciones en el mundo e implica 90% de riesgo de evolucionar a hepatitis crónica y sus complicaciones. La inmunoprofilaxis postparto (inmunoglobulina más vacuna) es la medida de prevención más efectiva. Sin embargo, puede existir fracaso a pesar de dicha intervención, debido a factores como alta carga viral o la presencia de HBeAg en la madre, los que sólo pueden evitarse si se hace el diagnóstico y tratamiento durante la gestación. En Chile, en el año 2019 se incorporó la vacunación en los recién nacidos, pero no existe aún cribado durante el embarazo, a diferencia de los países desarrollados. En los últimos años se ha experimentado un aumento acelerado de inmigración proveniente principalmente de América latina y el Caribe, con prevalencias altas en algunos de ellos. Chile debiese avanzar prontamente hacia el cribado de hepatitis B en embarazo.

BACKGROUND: Helicobacter pylori is detected by pathogen recognition receptors including toll-like receptors (TLR) and nucleotide-binding oligomerization domain (NOD)-like receptors, eliciting an innate immune response against this bacteria. The aim of this study was to assess if polymorphisms of TLR2, TLR4, TLR5, NOD1 and NOD2 genes are associated with gastric cancer, in particular in individuals infected with H. pylori. RESULTS: A case-control study of 297 gastric cancer patients and 300 controls was performed to assess the association of 17 polymorphisms. Analyses performed under the allele model did not find association with gastric cancer. However, NOD1 rs2075820 (p.E266K) showed association with intestinal-type gastric cancer among H. pylori infected subjects (OR = 2.69, 95% CI 1.41-5.13, p = 0.0026). The association was not statistically significant in diffuse-type gastric cancer cases (OR = 1.26, 95% CI 0.63-2.52, p = 0.51). When the analyses were performed in patients carrying H. pylori strains harboring the cag pathogenicity island (cagPAI), we noticed significant association with NOD1 rs2075820 (OR = 4.90, 95% CI 1.80-3.36, p = 0.0019), in particular for intestinal-type gastric cancer cases (OR = 7.16, 95% CI 2.40-21.33, p = 4.1 × 10- 4) but not among diffuse-type gastric cancer cases (OR = 3.39, 95% CI 1.13-0.10, p = 0.03). CONCLUSIONS: NOD1 rs2075820 increases the risk of intestinal-type gastric cancer among individuals infected with H. pylori, particularly in those harboring the cagPAI.

BACKGROUND: Treatments for Helicobacter pylori (H. pylori) eradication include the use of antibiotics and a proton-pump inhibitor. Antibiotic resistance is a major concern for two drugs: levofloxacin and clarithromycin. The aim was to determine the prevalence of levofloxacin resistance (LevoR) and clarithromycin resistance (ClaR) in an urban population in Santiago, Chile. METHODS: Gastric mucosa biopsies were obtained for DNA isolation from 143 H. pylori-positive individuals aged 18-80 years. Direct sequencing of the quinolone-resistance determining region (QRDR) of the gyrA gene was used to determine LevoR. ClaR was determined using restriction-fragment length polymorphism or 5'exonuclease assay. RESULTS: The prevalences of LevoR and ClaR were 29 and 27%, respectively. LevoR was higher in women than in men (39 vs. 13%, p <0.001), while no sex difference was observed for ClaR (pâ¯=â¯0.123). The prevalence of LevoR increased with age (p-trendâ¯=â¯0.004) but not for ClaR (p-trendâ¯=â¯0.054). In sex-stratified analyses, both LevoR and ClaR increased with age only among women. Older women (>50 years) had a higher probability to carry LevoR strains as compared to men. The prevalence of dual LevoR and ClaR was 12.6%. CONCLUSIONS: The prevalence of ClaR and LevoR is high in Santiago, according to International guidelines that recommend avoiding schemes with antibiotic resistance >15%. Our findings provide evidence to re-evaluate current therapies and guide empirical first- and second-line eradication treatments in Chile.

Genetic variants are considered risk factors for gastric cancer. To date, 61 polymorphisms have been identified as associated with this disease. The aim of the present study was to analyze the association of some of those polymorphisms with GC in Chile. We performed a case-control study including 310 gastric cancer cases and 311 controls to assess the association of 36 single-nucleotide polymorphisms genotyped by Global Screening Array (GSA). Three polymorphisms was significantly associated: PSCA rs2294008 (allele model, OR = 1.49, 95%CI 1.17-1.88, P = 1.08 × 10-3), IL-4 rs2243250 (allele model, OR = 1.28, 95%CI 1.01-1.62, P = 0.04), and MUC1 rs4072037 (allele model, OR = 0.78, 95%CI 0.61-0.99, P = 0.04).PSCA rs2294008, IL-4 rs2243250 and MUC1 rs4072037 are associated with gastric cancer in Chile. It suggests that those polymorphisms could be used as biomarkers to assess the genetic risk for this cancer outside of the previously studied populations, not only for East Asians and Caucasians populations.
