Fetal Hyperthyroidism Secondary to Maternal Basedow-Graves' Disease.

Fetal hyperthyroidism is a rare prenatal disease and can be life-threatening. The diagnosis is based on ultrasound in mothers with a history of Basedow-Graves' disease and elevation of thyrotropin receptor antibodies (TRAbs) levels. The treatment consists of antithyroid drugs. We present a mother with Basedow-Graves' disease, treated with radioactive iodine 16 years ago. She had an unplanned pregnancy at the age of 29 years, and an elevation of TRAbs (21 U/L) was found at the sixth week of pregnancy. At 22 weeks of gestation, fetal ultrasound displayed tachycardia, goiter, exophthalmos, and suspicion of craniosynostosis, hence methimazole was started. Concomitantly, suppressed maternal thyroid-stimulating hormone (TSH) was found. Her daughter was born at 33 + 6 weeks showing clinical and laboratory findings of hyperthyroidism. Consequently, treatment with methimazole was prescribed. Normal thyroid function was documented in the mother after giving birth. Clear explanation has not been found for the alteration of maternal TSH during pregnancy.

Long-term outcomes of the global tuberculosis and COVID-19 co-infection cohort.

BACKGROUND: Longitudinal cohort data of patients with tuberculosis (TB) and coronavirus disease 2019 (COVID-19) are lacking. In our global study, we describe long-term outcomes of patients affected by TB and COVID-19. METHODS: We collected data from 174 centres in 31 countries on all patients affected by COVID-19 and TB between 1 March 2020 and 30 September 2022. Patients were followed-up until cure, death or end of cohort time. All patients had TB and COVID-19; for analysis purposes, deaths were attributed to TB, COVID-19 or both. Survival analysis was performed using Cox proportional risk-regression models, and the log-rank test was used to compare survival and mortality attributed to TB, COVID-19 or both. RESULTS: Overall, 788 patients with COVID-19 and TB (active or sequelae) were recruited from 31 countries, and 10.8% (n=85) died during the observation period. Survival was significantly lower among patients whose death was attributed to TB and COVID-19 versus those dying because of either TB or COVID-19 alone (p<0.001). Significant adjusted risk factors for TB mortality were higher age (hazard ratio (HR) 1.05, 95% CI 1.03-1.07), HIV infection (HR 2.29, 95% CI 1.02-5.16) and invasive ventilation (HR 4.28, 95% CI 2.34-7.83). For COVID-19 mortality, the adjusted risks were higher age (HR 1.03, 95% CI 1.02-1.04), male sex (HR 2.21, 95% CI 1.24-3.91), oxygen requirement (HR 7.93, 95% CI 3.44-18.26) and invasive ventilation (HR 2.19, 95% CI 1.36-3.53). CONCLUSIONS: In our global cohort, death was the outcome in >10% of patients with TB and COVID-19. A range of demographic and clinical predictors are associated with adverse outcomes.

Influence of Environmental Pollution and Living Conditions on Parasite Transmission among Indigenous Ecuadorians.

The purpose of this study was to evaluate the influence of environmental pollution and the living conditions of indigenous Ecuadorians on the transmission of enteroparasites in an Andean agricultural area located at high altitude. Environmental pollution was recorded after observation in each community. The parasites were identified by microscopic sediment analysis using physiological saline solution from macerated arthropods, washed vegetables, and human stools, utilizing four coproparasitological techniques (direct examination, Kato-Katz, ether concentration, and Ziehl-Neelsen). The results show that the inadequate disposal of human and animal excreta that contaminate soil and water, incorrect food hygiene, inadequate sanitary infrastructure in houses, a lack of animal veterinary care, and rodent proliferation are important reservoirs of zoonotic parasites. The use of excrement as fertilizer increases the number of flies, which act as mechanical vectors, and vegetables grown in areas with disperse infective parasitic forms act as vehicles that are marketed at the local, regional, and international levels. These analyses verify contamination levels of 52.7% in mechanical vectors, 70.6% in vegetables, and 98.2% in human stools. The agricultural communities analyzed maintained poor hygienic-sanitary and environmental conditions, which had a significant influence on the transmission of enteroparasites that affect human health.

Temporal lobe epilepsy: Evaluation of central and systemic immune-inflammatory features associated with drug resistance.

Neuroinflammation is probably one of the factors involved in drug resistance in people with epilepsy. Finding peripheral markers reflecting the intensity of neuroinflammation could be of great help to decide for which patients anti-inflammatory treatment might be an option. In this context, peripheral cytokines levels and lymphocyte phenotypes were assessed by ELISA and flow cytometry in 3 groups of subjects: drug resistant patients with temporal lobe epilepsy (DR-TLE), non DR-TLE patients and healthy controls. The same parameters were assessed in brain tissue in the DR-TLE group. Differences in the peripheral immune-inflammatory status between the 3 groups of subjects, and correlations between the central and peripheral immune-inflammatory status in DR-TLE patients were evaluated. Forty-one patients with DR-TLE, ten with non-DR-TLE and twenty controls were included. In the periphery, decrease in regulatory cells were observed in DR-TLE patients compared to controls. In addition, significant increase of IL-6 and IL-5 was observed in patients with epilepsy (particularly DR-TLE patients). Two groups of DR-TLE patients with significant differences in several central inflammatory parameters were identified in a cluster analysis. The inflammatory cluster was associated with a peripheral increase of CD4+CD38+ cells and different significant correlations between central and systemic inflammatory parameters were observed. Although their interpretation is not immediate, they demonstrate a clear dialogue between central and peripheral inflammatory reactions. In conclusion, our results add new elements to better understand the interactions between the central and peripheral compartments in patients with DR-TLE, and to help better define treatment options in this group of patients.

Natural history of extraparenchymal neurocysticercosis.

BACKGROUND: In patients affected by neurocysticercosis (NCC), the extraparenchymal location of the parasites generates the most severe form of the disease. Due to the difficulty in its diagnosis and management, there are still many questions; in particular, the natural history of parasites at this location is not well known. METHODS: We included 21 patients with vesicular extraparenchymal NCC who had not received treatment for at least 18 months. We collected their demographic and clinical data, compared their imaging studies at the beginning and the end of the period without treatment and classified the patients, taking into account the evolution of their parasitic burden. RESULTS: A total of 10 men and 11 women were included. Patients had undergone a period of 63±48 months without treatment. During this period, 8 patients (38.1%) showed an increase, 7 (33.3%) a decrease and 6 (28.6%) showed no change in parasite burden. CONCLUSION: The natural history of extraparenchymal cysticerci is heterogeneous. The results show the ability of parasites to survive for a long time in the extraparenchymal location and explain the chronicity of the disease in some patients. The links between these findings and the difficulties in the therapeutic management of extraparenchymal NCC patients should be studied.

Anthropometric and hematological tests to diagnose nutritional deficiencies in schoolchildren of indigenous communities living in the Andean region of Ecuador / Análise antropométrica e hematológica para o diagnóstico de deficiências nutricionais em escolares de comunidades indígenas que vivem na cordilheira dos Andes no Equador

ABSTRACT Objective To carry out the anthropometric and biometric-hematological assessments in schoolchildren of the Andean region of Ecuador, in order to improve the diagnosis of nutritional deficiencies. Methods The study has been carried out in the San Juan School (Chimborazo, Ecuador), located at 3,240m of altitude, to 36 children of 5 and 6 years old. Anthropometric analyses (weight, height and body mass index), and hematocrit and hemoglobin concentrations were measured. The hemoglobin measurement was evaluated considering the normal value and the one adapted to the altitude of the area. Results The schoolchildren showed high prevalence of stunting (44%). The values of hematocrit (.=0.001) and hemoglobin (.=0.003) were higher in girls. It should be highlighted that using the normal value of hemoglobin, anemia was not detected. However almost a fifth of the schoolchildren studied were diagnosed with anemia when we applied the correction factors adapted to the altitude. Conclusion The use of correction factors adapted to the altitude is considered essential to do the hematology test in populations that live in high altitude in order to avoid a false diagnosis. Moreover, it is necessary to establish the environmental factors related to the stunted growth of this population of the Andean region.

RESUMO Objetivo Realizar avaliações antropométricas e biométrico-hematológicas em escolares da cordilheira dos Andes no Equador, a fim de melhorar o diagnóstico de deficiências nutricionais. Métodos O estudo foi realizado na escola San Juan (Chimborazo, Equador), localizada a 3240 metros acima do nível do mar, a 36 crianças de 5 e 6 anos de idade. Foram analisadas as medidas antropométricas (peso, altura e índice de massa corporal) e as concentrações de hemoglobina e hematócrito. A medida da hemoglobina foi avaliada considerando os valores absolutos e os corrigidos pela altura geográfica. Resultados A população escolar apresentou alta prevalência de altura baixa (44%). Os valores de hematócrito (p=0,001) e hemoglobina (p=0,003) foram maiores nas meninas. Deve-se destacar que usando o valor normal da hemo-globina, a anemia não foi detectada. No entanto, quase um quinto dos escolares estudados foram diagnosticados com anemia quando os fatores de correção adaptados à altitude foram aplicados. Conclusão O uso de fatores de correção adaptados à altitude é considerado fundamental ao fazer uma biometria a os habitantes da zona para evitar um diagnóstico errôneo. Além disso, é necessário estabelecer os fatores ambientais associados ao retardo do crescimento que existe nesta região dos Andes.

Caracterización de lesiones intraepiteliales en mujeres del cantón Penipe, Ecuador. Noviembre 2014 / Characterization of intraepithelial lesions in women of Penipe town, Ecuador. Novem-ber 2014

El proceso investigativo tuvo un enfoque cuantitativo, de tipo observacional, descriptivo, transversal; con el propósito de caracterizar las lesiones intraepiteliales en 100 pacientes del cantón Penipe, con edades comprendidas entre 20 a 65 años, que asistieron a consulta gineco-lógica del Centro de Erradicación del Bocio y Capacitación a Minusválidos (CEBYCAM), durante el mes de noviembre de 2014. Los datos fueron obtenidos empleando la técnica de la medición, a través del empleo del Sistema Internacional de Reporte de Bethesda. El prome-dio de la edad fue 41.44 años (± 13.60); la media aritmética de la edad de inicio de las relacio-nes sexuales fue de 16,37 (± 4.49); predominaron las mujeres con dos hijos, aquellas cuyo test resultó negativo (88 %) y las que no utilizaban algún método anticonceptivo, así como para la presencia de microorganismos con potencial patológico. La prueba de correlación de Pearson arrojó la existencia de una relación fuerte y positiva entre las variables paridad y edad.

The researching process had a quantitative, observational, descriptive, cross-sectional approach. It aimed to characterize the intraepithelial lesions in 100 patients from Penipe town, aged between 20 and 65 years, who are treated at the gynecological consultation of Centro de Erradicación del Bocio y Capacitación a Minusválidos during the month of November 2014. The data were obtained through the use of the Bethesda International Reporting System measurement technique. The age was on average 41.44 (± 13.60); the arithmetic mean of the age of onset of sexual intercourse was 16.37 (± 4.49); women with two children predominated, those whose test was negative (88%) and those who did not use any contraceptive method, as well as the presence of microorganisms with pathological potential. The Pearson correlation test showed the existence of a strong and positive relationship between parity and age variables.

Dynamic contrast-enhanced magnetic resonance imaging as a prognostic factor in predicting event-free and overall survival in pediatric patients with osteosarcoma.

BACKGROUND: The objective of this study was to prospectively evaluate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as an early imaging indicator of tumor histologic response to preoperative chemotherapy and as a possible prognostic factor for event-free survival (EFS) and overall survival in pediatric patients with newly diagnosed, nonmetastatic osteosarcoma who were treated on a single, multi-institutional phase 2 trial. METHODS: Three serial DCE-MRI examinations at week 0 (before treatment), week 9, and week 12 (tumor resection) were performed in 69 patients with nonmetastatic osteosarcoma to monitor the response to preoperative chemotherapy. Four DCE-MRI kinetic parameters (the influx volume transfer constant [K(trans) ], the efflux rate constant [k(ep) ], the relative extravascular extracellular space [v(e) ], and the relative vascular plasma space [v(p) ]) and the corresponding differences (ΔK(trans) , Δk(ep) , Δv(e) , and Δv(p) ) of averaged kinetic parameters between the outer and inner halves of tumors were calculated to assess their associations with tumor histologic response, EFS, and overall survival. RESULTS: The parameters K(trans) , v(e) , v(p) , and k(ep) decreased significantly from week 0 to week 9 and week 12. The parameters K(trans) , v(p) , and Δk(ep) at week 9 were significantly different between responders and nonresponders (P = .046, P = .021, and P = .008, respectively). These 3 parameters were indicative of histologic response. The parameter Δv(e) at week 0 was a significant prognostic factor for both EFS (P = .02) and overall survival (P = .03). CONCLUSIONS: DCE-MRI was identified as a prognostic factor for EFS and overall survival before treatment on this trial and was indicative of a histologic response to neoadjuvant therapy. Further studies are needed to verify these findings with other treatment regimens and establish the potential role of DCE-MRI in the development of risk-adapted therapy for osteosarcoma.

Acardiac fetus complicating a triplet pregnancy: management and outcome.

OBJECTIVE: To report our experience with the management of triplet pregnancies complicated by an acardiac fetus. METHODS: During the 5-year period from 2003 to 2008, five cases were identified. The prenatal sonographic findings, antepartum course, antenatal intervention if performed, and perinatal outcome of each case were reviewed. RESULTS: Four pregnancies were spontaneously conceived and one was achieved by in vitro fertilization. Three pregnancies were dichorionic and two were monochorionic, and two acardiac fetuses were part of a monoamniotic set. All cases underwent an early sonographic examination, but the diagnosis was only made in the first trimester in only two cases, as the acardiac fetus was overlooked or inaccurately identified as a dead fetus in the remaining three cases. Early fetal demise before 12 weeks occurred in a case of monochorionic-triamniotic triplets. Percutaneous laser coagulation of the main intra-abdominal vessel was attempted at 17 weeks in two cases, with subsequent delivery after 34 weeks and perinatal survival of three of the four structurally normal fetuses. In the other two pregnancies which were managed expectantly, both were complicated by severe preterm delivery with perinatal survival of three of the four structurally normal fetuses. Overall, there were no survivors in one case, one twin survived in two cases, and two twins survived in the remaining two cases. None of the survivor had neurological sequelae. CONCLUSIONS: The presence of an acardiac fetus in a triplet pregnancy carries a high risk for poor pregnancy outcome, including fetal death and severe preterm labor. Prenatal intervention may be indicated in some cases, but does not prevent fetal death of the pump twin.

La presente investigación surge de la inquietud por conocer cuáles son los factores que frenan el cumplimiento de la Ley de Regulación del Trabajo Asalariado del Hogar, más allá de su desconocimiento por parte de la población en general. El estudio plantea que este incumplimiento se enraíza en las razones y construcciones sociales del funcionamiento mismo de la sociedad boliviana y en la manera cómo los empleadores representan a las trabajadoras del hogar y las relaciones que los unen.

Intrathoracic dislodgement of pleuro-amniotic shunt. Three case reports with long -term follow-up.

BACKGROUND: Intrathoracic shunt dislodgement is a rare, although significant, complication of pleuro-amniotic shunting. In a previously reported case, the abnormally located shunt caused constriction of the pulmonary hilum resulting in neonatal death. CASES: Three cases of severe fetal pleural effusion treated by pleuro-amniotic shunting at 33, 26 and 30 weeks of gestation and complicated by dislodgement of the shunt into the fetal chest are presented. These cases were collected from three fetal medicine referral centers, where 15 pleuro-amniotic shunts have been inserted in a total of 13 fetuses (11 unilateral and 2 bilateral procedures), giving prevalence for this complication of 20%. The indication for shunting was severe bilateral pleural effusions and hydrops in one case, and unilateral pleural effusion with marked mediastinal shift in 2 others. Intrathoracic dislodgement was diagnosed by ultrasound at 33, 29 and 39 weeks, and the infants were delivered at 35, 34 and 39 weeks of gestation, respectively. There were no complications associated with the malposition of the shunt within the fetal chest and clinical follow-up from 10 months to 2 years of age has demonstrated asymptomatic infants. CONCLUSION: The complication of intrathoracic dislodgement of a pleuro-amniotic shunt can be recognized prenatally by ultrasound. Prevention of this complication seems difficult, but if recognized, a conservative approach appears to be a sensible management option. Since the material of the shunt is inert, its presence within the pleural cavity is unlikely to be associated with an inflammatory foreign body response and, therefore, it should not cause long-term pulmonary complications.

Jovenes por la vida: SIDA: percepciones y vivencias de l@s jovenes de El Alto / sss

Nivel de conocimientos y estudio piloto del grupo mas vulnerable cerca del sida en estudiantes de 14 a 18 años distrito IV El Alto-Bolivia 2002 / Proficiency level and pilot study of the most vulnerable group near the AIDS in students from 14 to 18 years district IV The High - Bolivia 2002

El presente proyecto de investigación tiene como objeto determinar el nivel de conocimiento, acerca del VIH/SIDA en estudiantes de 14 a 18 años pertenecientes a colegios del Distrito 4 de la ciudad de El Alto; identificar el grupo vulnerable con menor conocimiento acerca del VIH/SIDA y evaluar el resultado de la intervención educativa con estudiantes vulnerablesal VIH/SIDA; diseñar una intervencion educativa con estudiantes vulnerables al VIH/SIDA y evaluar el resultsdo de la intervención educativa. La metodologia de investigación estara dividida en dos fases, una primera parte de corte transversal y una segunda parte de intervención. Se aplicara un instrumento de evaluación para conocer la información que tienen acerca de esta enfermedad, para lo cual se elaboro una planilla compueesta por dos partes. Una donde se obtendran datos generales del participante y la otra de tipo personal, se dirige a recoger datos sobre el nivel de conocimiento acerca del SIDA. Posteriormente, se realizara un estudio de intervención educativa con el grupo de estudiantes con mayor riesgo frente a esta enfermedad, "Este estudio se realizara despues del analisis de una primera encuesta aplicada". Finalmente se aplicara una segunda evaluación midiendo las mismas variables con el que se pretende una mejoria de nivel de conocimientos sobre SIDA. La investigación es llevada adelante ya que en nuestro medio no existe estudios realizados en este sector de la población, siendo este el mas afectado actualmente en el mundo por esta enfermedad, por tanto exige de nuestra competencia, y hasta el momento actual lo mas efectivo y de mejor resultado es la prevencion, por lo que enfatizamos en que debe profundizarse el trabajo en este sentido. El proposito de nuesttra investigación es una problematica, se interesa en conocer ¿Cuan expuestos estan los jovenes a contraer el VIH?. En la actualidad en nuestro pais la pandemia del SIDA no afecta de sobremanera a nuestra poblacion, como el de paises vesinos o de todo el mundo, pero queda claro que el VIH/SIDA en la actualidad se sierne sobre un grupo de población joven, facilitado por la pobreza y el inicio sexual precoz
