Usefulness of biomarkers to predict prognosis after heart transplant.

INTRODUCTION AND OBJECTIVES: Heart transplant (HT) represents a major physiological stress, resulting in elevated levels of analytical biomarkers. This study aimed to determine whether changes in biomarker levels after HT can identify patients with a poor prognosis. METHODS: A prospective longitudinal noninterventional study was conducted in 149 consecutive patients undergoing HT from July 2017 to July 2023. Biomarkers were assessed before HT and at 6, 24, 48, 72, and 96hours after HT. The biomarkers analyzed were high-sensitivity troponin T, N-terminal pro-B-type natriuretic peptide (NT-proBNP), creatinine, and lactic acid. The primary outcome was a composite of death and severe primary graft failure (PGF). RESULTS: NT-proBNP and troponin levels remained highly elevated throughout the period and stabilized from the first 24hours post-HT. Lactate levels stabilized after the first 24hours, and creatinine from the second day onward. Exitus occurred in 23 (15%) of the patients, and severe PGF in 26 (17%). All biomarkers were significantly associated with the incidence of the combined event (P <.0001). Receiver operating characteristic curve analysis at 24hours showed significant areas under the curve (P=.0001). The greatest discriminatory power was observed for the NT-proBNP curve. A value of 10 000 pg/mL had a sensitivity of 90% and specificity of 80%. CONCLUSIONS: A significant elevation of post-HT analytical biomarkers was associated with mortality and/or severe PGF. Among the biomarkers analyzed, NT-proBNP was the most accurate in classifying patients.

Update in imaging tests used for the localization of parathyroid pathology.

Preoperative localization of parathyroid pathology, generally a parathyroid adenoma, can be difficult in some cases due to the anatomical variants that these glands present. The objective of this review is to analyse the different imaging techniques used for preoperative localization of parathyroid pathology (scintigraphy, ultrasound, CT, MRI and PET). There is great variability between the different tests for the preoperative localization of parathyroid pathology. The importance of knowing the different diagnostic options lies in the need to choose the most suitable test at each moment and for each patient for an adequate management of primary hyperparathyroidism (PHP) with surgical criteria.

[Factors associated with caregiver burden in primary caregivers of older adults with type2 diabetes]. / Factores asociados a la sobrecarga del cuidador en cuidadores primarios de personas adultas mayores con diabetes tipo2.

OBJECTIVE: To characterize the profile of the informal primary caregiver (IPC) of adult patients with type2 diabetes (T2D) and the possible factors associated with caregiver collapse (CC). DESIGN: Observational, descriptive, cross-sectional and analytical study. SITE: Ambulatory Care Medical Unit. PARTICIPANTS: Mexican CPIs of adult patients with T2D. MAIN MEASUREMENTS: Data were collected through a prolective design using the Zarit scale and a structured survey on sociodemographic factors. A descriptive statistical analysis and univariate and multivariate logistic regression models were performed. RESULTS: The CPI profile is assumed by: women, people aged 36-58, daughters, people with a secondary and high school educational level, married, Catholic, with income <8,900 Mexican pesos, own home, inhabited by a maximum of 5 inhabitants, with support networks, who have dedicated >5years to the care of their patient, without training and with chronic diseases. The risk factors that increase the risk of CC are: being a woman (OR=11.03; 95%CI: 1.49-81.95), having a history of more than 5years of having assumed the role of caregiver (OR=2, 65; 95%CI: 1.07-6.55), living in one's own house (OR=3.03; 95%CI: 1.04-8.82), with 6 or more inhabitants (OR=2.41; 95%CI: 1.08-5.38). The support of other family members and/or friends was associated as a protective factor (OR=0.15; 95%CI: 0.07-0.33). CONCLUSIONS: Prevention programs are required to avoid CC and complications, as well as interventions to improve the quality of life of the CPI and patients in care, incorporating strategies to generate and/or increase their family and social support networks.

Efecto de una intervención cognitivo-conductual en cuidadores de niños con TEA: depresión, ansiedad, estrés y calidad de vida / Effect of a cognitive-behavioral intervention on caregivers of children with ASD: depression, anxiety, stress, and quality of life

Este estudio tuvo como objetivo evaluar el efecto de una intervención cognitivo conductual en la sintomatología de depresión, ansiedad y estrés, la sobrecarga percibida y la calidad de vida en cuidadores de niños con trastorno del espectro autista. Se realizó un estudio experimental con grupo intervención y control, con mediciones de autorreporte pretest-postest. Participaron en el estudio un total de 53 cuidadores: 22 en el grupo experimental y 31 en el grupo control en lista de espera. La mayoría de los participantes fueron mujeres de entre 35 y 64 años, casadas o en una relación formal, con estudios profesionales o superiores y que realizaban alguna actividad remunerada. Los resultados del análisis intergrupal mostraron una disminución de la sintomatología asociada al estrés y sobrecarga percibida y un aumento en la calidad de vida en el grupo experimental. Los datos intragrupales dan cuenta de que, los sujetos del grupo control no tuvieron cambios en ninguna variable, por el contrario, en el grupo experimental se observa una disminución significativa en los índices de ansiedad, estrés y sobrecarga percibida y un aumento en la calidad de vida. Todos estos cambios ocurrieron con tamaños de efecto mediano y grande. Se analizan los mecanismos de cambio y se discuten los hallazgos del estudio a la luz de sus limitaciones. Se concluye que una intervención cognitivo conductual es una estrategia con efectos positivos para brindar apoyo psicológico a los cuidadores de niños con autismo. (AU)

This study aimed to evaluate the effect of a cognitive behavioral intervention on symptoms of depression, anxiety and stress, perceived overload and quality of life in caregivers of children with autism spectrum disorder. An experimental study was conducted out with an intervention and control group, with self-report pretest-posttest measurements. A total of 53 caregivers participated in the study: 22 in the experimental group and 31 in the waiting list control group. The majority of participants were women between 35 and 64 years old, married or in a formal relationship, with professional or higher education and who carried out some paid activity. The results of the intergroup analysis showed a decrease in the symptoms associated with stress and perceived overload and an increase in the quality of life in the experimental group. Intra-group data showed that the subjects of the control group had no change in any variable, in contrast, in the experimental group there was a significant decrease in anxiety, stress and perceived overload indices and an increase in the quality of life. All these changes occurred with medium and large effect sizes. The mechanisms of change are analyzed and the study's findings are discussed in light of its limitations. It is concluded that a cognitive behavioral intervention is a strategy with positive effects for providing psychological support to caregivers of children with autism. (AU)

The authors commented on the rarity of this neoplasm which is usually located in the midline near the pineal gland, the alpha-fetoprotein and chorionic gonadotropin markers, the indication for neoadjuvant chemotherapy and reduced dose radiotherapy, and the favorable prognosis, with an overall survival of up to 70%. They emphasized the current limitations in terms of dose and extent of radiation to the CNS, as well as the use of chemotherapy alone or neoadjuvant chemotherapy. The additional comments that we are about to present seek to highlight the importance of the initial report, increasing interest in primary CNS tumors (provided by Infomedic International)

Indicación, realización y resultado del cateterismo de venas adrenales en pacientes con hiperaldosteronismo primario / Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism

El hiperaldosteronismo primario (HAP) es una causa importante de hipertensión arterial (HTA) secundaria. El estudio del mismo precisa de una alta sospecha clínica, además de un estudio hormonal que confirme la hipersecreción hormonal. Es importante iniciar el tratamiento adecuado una vez se confirma el diagnóstico, y para ello es preciso demostrar si la hipersecreción hormonal es unilateral (pacientes que podrían ser tributarios a tratamiento quirúrgico) o bilateral (pacientes que son tributarios a tratamiento únicamente farmacológico). En el Hospital del Mar desde el año 2016 existe un equipo de trabajo multidisciplinar en el que participan nefrólogos, endocrinólogos, radiólogos y cirujanos para evaluar los casos con sospecha de hiperaldosteronismo y consensuar el mejor abordaje diagnóstico-terapéutico de estos pacientes, incluyendo la necesidad de cateterismo venoso adrenal, que es una técnica que en los últimos años se ha erigido como gold standard para el estudio del HAP. En el presente estudio recogemos la experiencia de nuestro centro en la realización de cateterismo venoso adrenal y en la utilidad de este para el manejo de tales pacientes (AU)

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our center in performing adrenal vein catheterization and its usefulness for the management of these patients (AU)

Anti-parietal cell antibodies as a potential biomarker for interstitial lung disease associated with primary Sjögren's syndrome / Anticuerpos contra las células parietales como biomarcadores potenciales de enfermedad pulmonar intersticial relacionada con el síndrome de Sjögren primario

Background ILD is a common manifestation in pSS and is associated with an increased risk of death. APCA are strongly expressed by hyperplastic alveolar epithelial cells in the fibrotic lung and are associated with an accelerated decline in lung function in IPF. In the present study, we aimed to evaluate the clinical utility of APCA in ILD patients with pSS. Methods Clinical, laboratory, PFTs and imaging data from pSS patients were reviewed, and the ESSDAI was utilized to evaluate disease activity. HRCT semiquantitative scoring was conducted. We compared the clinical characteristics of pSS patients with and without ILD and carried out logistic regression analysis of risk factors for ILD in pSS. Results A total of 74 patients with pSS and 40 HCs were included in the study. ILD was more commonly observed in the APCA-positive group than in the APCA-negative group. The quantitative levels of APCA were positively correlated with the imaging score. Multivariate analysis found that the long disease duration, elevated APCA and elevated KL-6 level were independent risk factors for ILD in pSS patients. The area under ROC curve for APCA was 0.6618, and the threshold concentration was 153.82ng/ml (sensitivity 45.24%, specificity 87.50%). Conclusion APCA level is an independent risk factor and might be a potential biomarker for ILD in patients with pSS (AU)

Antecedentes La enfermedad pulmonar intersticial (EPI) es una manifestación común del síndrome de Sjögren primario (SSp) y está relacionada con un mayor riesgo de muerte. Los anticuerpos anticélulas parietales (AACP) están fuertemente expresados por células epiteliales alveolares proliferantes en los pulmones fibróticos y están relacionados con la disminución acelerada de la función pulmonar en la gibrosis pulmonar idiopática. En este estudio, pretendemos evaluar la aplicación clínica de la AACP en pacientes con EPI con SSp. Método Se revisaron los datos clínicos, de laboratorio, de función pulmonar e imágenes de los pacientes con SSp y se utilizó la ESSDAI para evaluar la actividad de la enfermedad en general. Se registraron 5 características principales de imagen pulmonar de la EPI y 2 radiólogos ciegos experimentados realizaron una puntuación semicuantitativa de HRCT de forma independiente. Comparamos las características clínicas de los pacientes con y sin EPI con SSp y realizamos un análisis de regresión logística de los factores de riesgo de EPI en SSp. Resultados Un total de 74 pacientes con SSp y 40 controles sanos fueron incluidos en el estudio. La EPI es más común en el grupo positivo de AACP que en el grupo negativo de APCA. El nivel cuantitativo de AACP, está positivamente relacionado con la puntuación de imagen. El análisis multifactorial encontró que la larga duración, el aumento de los niveles de AACP y el aumento de los niveles de KL-6 fueron factores de riesgo independientes para la EPI en pacientes con SSp. El área bajo la curva ROC de AACP es de 0,6618 y la concentración umbral fue de 153,82 ng/ml (sensibilidad 45,24% y especificidad 87,50%). Conclusiones Los niveles de AACP son un factor de riesgo independiente y pueden ser biomarcadores potenciales de EPI en pacientes con SSp (AU)

Luxación intrusiva en dentición primaria: reporte de caso / Luxação intrusiva na dentição decídua: relato de caso clínico / Intrusive luxation in primary dentition: clinical report

La luxación intrusiva es el tipo más común de lesión traumática en la dentición primaria, caracterizada por el desplazamiento del diente hacia el interior del alvéolo. Requieren minucioso examen clínico, buena radiografía y seguimiento del caso, siendo el prognóstico desfavorable, principalmente por la probabilidad de daño al germen del diente permanente. Este trabajo tiene como objetivo reportar un caso clínico de luxación intrusiva en dentición primaria, desde el diagnóstico hasta el seguimiento. Se trata de un paciente masculino, de 3 años, que acudió a la Emergencia de la Clínica de Especialidades Infantiles ­ Universidad Estatal de Londrina (UEL) por traumatismo dentoalveolar en la región antero-superior ocurrido hace tres días. En el examen físico, se observó que el diente 61 presentaba intrusión de grado II con un tercio de la corona visible y el diente 62 intrusión de grado I, con más de un tercio de la corona visible. Radiográficamente se observa inclinación vestibular, sin fractura de la placa ósea, por lo que se optó por un tratamiento conservador, a la espera de la reerupción espontánea de los dientes afectados. Se informó a los padres sobre posibles consecuencias de este tipo de traumatismo y la necesidad de consultas de seguimiento clínico y radiológico. Después de ocho meses de seguimiento, los dientes erupcionaron satisfactoriamente. Es de suma importancia establecer un protocolo de observación y control del diente en el cual se ha identificado el trauma, observando signos y síntomas de los tejidos involucrados en el trauma para reducir secuelas en ambas denticiones

A luxação intrusiva é o tipo de lesão traumática mais frequente na dentição decídua, caracterizada pelo deslocamento do dente para o alvéolo. As intrusões requerem exame físico minucioso, radiografias de valor diagnóstico e acompanhamento do caso, pois o prognóstico é desfavorável, principalmente pela probabilidade de danos ao germe dentário permanente. Este trabalho tem como objetivo relatar um caso clínico de luxação intrusiva na dentição decídua, desde o diagnóstico até o acompanhamento. Trata-se de paciente do sexo masculino, 3 anos de idade, atendido no Pronto Socorro do Ambulatório de Especialidades Infantis da Universidade Estadual de Londrina (UEL) devido a trauma dento-alveolar em região ântero-superior ocorrido há três dias. Ao exame físico intraoral, observou-se que o dente 61 apresentava intrusão grau II (um terço da coroa visível) e o dente 62 apresentava intrusão grau I, com mais de um terço da coroa visível. Radiograficamente foi observada inclinação vestibular, sem fratura da tábua óssea. Assim, optou-se pelo tratamento conservador, aguardando a reerupção espontânea dos dentes envolvidos. Além disso, os pais foram informados sobre as possíveis consequências deste tipo de trauma e a necessidade de consultas de proservação clínica e radiográfica. Após oito meses de acompanhamento, os dentes erupcionaram satisfatoriamente. É de extrema importância estabelecer um protocolo de observação e controle do dente traumatizado, observando sinais e sintomas dos tecidos envolvidos no trauma para reduzir sequelas em ambas as dentições.

Intrusive dislocation is the most frequent type of traumatic injury in the primary dentition, characterized by displacement of the tooth into the alveolus. Intrusions require a thorough physical examination, radiographs of diagnostic value, and follow-up of the case, since the prognosis is unfavorable, mainly due to the probability of damage to the permanent tooth germ. This work aims to report a clinical case of intrusive dislocation in the primary dentition, from diagnosis to follow-up. This is a male patient, 3 years old, who attended in the Emergency of the Children's Specialty Clinic ­ State University of Londrina (UEL) due to dento-alveolar trauma in the antero-superior region that occurred three days ago. On clinical examination, tooth 61 had grade II intrusion (one-third of the crown visible), and tooth 62 with grade I intrusion, with more than one-third of the crown visible. Radiographically, a buccal inclination was observed, with no fracture of the bone plate. Thus, we opted for conservative treatment, waiting for the spontaneous re-eruption of the teeth involved. Furthermore, parents were informed about the possible consequences of this type of trauma and the need for clinical and radiographic follow-up consultations. After eight months of follow-up, the teeth erupted satisfactorily. It is extremely important to establish a protocol for observation and control of the traumatized tooth, observing signs and symptoms of the tissues involved in the trauma to reduce sequelae in both dentitions

Predictive models for hepatocellular carcinoma development after sustained virological response in advanced hepatitis C / Modelos predictivos para el desarrollo de carcinoma hepatocelular tras la respuesta viral sostenida en pacientes con hepatitis C avanzada

Background & aims: Life-long hepatocellular carcinoma (HCC) surveillance is recommended after sustained virological response (SVR) in patients with advanced hepatitis C. Since the identification of patients who could be safely discontinued for surveillance is essential, we aimed to identify subsets of patients with low-risk HCC. Methods: 491 patients with advanced and compensated fibrosis (≥F3) were prospectively followed after achieving SVR with interferon-free therapies. Clinical–biological parameters and liver stiffness measurement (LSM) were performed before starting treatment (ST) and at SVR, and HCC surveillance was carried out. Results: During a median follow-up of 49.8 months, 29 (5.9%) patients developed HCC [incidence rate: 1.6/100 patient-years (PYs)]. Two predictive models based on LSM (Model-A) or FIB-4 score (Model-B) were proposed. Only SVR parameters were included in the models, because they showed a higher accuracy for predicting HCC than ST measurements. Variables independently associated with HCC were LSM (HR, 1.03; 95% CI, 1.01–1.05), age (HR, 1.04; 95% CI, 1.01–1.08) and albumin levels (HR, 0.90; 95% CI, 0.84–0.97) in Model-A, and FIB-4 (HR, 1.22; 95% CI, 1.08–1.37) and albumin (HR, 0.90; 95% CI, 0.84–0.97) in model-B. Both models allow HCC risk stratification, identifying low-risk groups with an HCC incidence rate of 0.16/100 and 0.25/100 PYs, respectively. An overall increased hazard of HCC was observed over time. (AU)

Antecedentes y objetivos: En pacientes con hepatitis C avanzada se recomienda la vigilancia del carcinoma hepatocelular (CHC) de por vida tras la respuesta viral sostenida (RVS). La identificación de pacientes que podrían interrumpir de manera segura el screening es esencial, por ello nuestro objetivo fue identificar subgrupos de pacientes con bajo riesgo de desarrollo de CHC. Métodos: Se realizó un seguimiento prospectivo de 491 pacientes con fibrosis avanzada y compensada (≥F3) tras la RVS obtenida con terapias libres de interferón. Se registraron parámetros clínico-biológicos y se midió la rigidez hepática mediante elastografía de transición (ET) antes del inicio del tratamiento y en la respuesta viral sostenida y se realizó screening para el desarrollo de CHC. Resultados: Durante una mediana de seguimiento de 49,8 meses, 29 (5,9%) pacientes desarrollaron CHC. (Tasa de incidencia: 1,6/100 pacientes-año [PA]). Se propusieron dos modelos predictivos basados en la puntuación de ET (Modelo-A) o FIB-4 (Modelo-B). Se incluyeron los parámetros en RVS en los modelos porque mostraron una mayor precisión para predecir CHC que las mediciones basales. Las variables asociadas de forma independientes con CHC fueron: ET (HR 1,03 IC; IC 95%, 1,01-1,05), edad (HR 1,04; IC 95%, 1,01-1,08) y niveles de albúmina (HR 0,90; IC 95%, 0,84-0,97) en el Modelo-A, y FIB-4 (HR 1,22; IC 95%, 1,08-1,37) y albúmina (HR 0,90; IC 95%, 0,84-0,97) en el Modelo-B. Ambos modelos permiten la estratificación del riesgo de CHC, identificando grupos de bajo riesgo con una tasa de incidencia de CHC de 0,16/100 y 0,25/100 PA, respectivamente. Se observó un aumento general del riesgo de desarrollar CHC con el tiempo. (AU)

Primary aldosteronism: Practical recommendations for treatment and follow-up / Hiperaldosteronismo primario: recomendaciones prácticas de tratamiento y seguimiento

Primary aldosteronism (PA) is the most common cause of secondary arterial hypertension. For unilateral cases, surgery offers the possibility of cure, with unilateral adrenalectomy being the treatment of choice, whereas bilateral forms of PA are treated mainly with mineralocorticoid receptor antagonists (MRA). The goals of treatment for PA due to either unilateral or bilateral adrenal disease include reversal of the adverse cardiovascular effects of hyperaldosteronism, normalization of serum potassium in patients with hypokalemia, and normalization of blood pressure. The Primary Aldosteronism Surgery Outcome group (PASO) published a study defining clinical and biochemical outcomes based on blood pressure and correction of hypokalemia and aldosterone to renin ratio (ARR) levels for patients undergoing total unilateral adrenalectomy for unilateral PA. In this review, we provide several practical recommendations for the medical and surgical management and follow-up of patients with PA. (AU)

El hiperaldosteronismo primario (HAP) es la causa más frecuente de hipertensión arterial secundaria. Para los casos unilaterales, la cirugía ofrece la posibilidad de curación, siendo la adrenalectomía unilateral el tratamiento de elección, mientras que las formas bilaterales de HAP se tratan principalmente con antagonistas del receptor de mineralocorticoides (ARM). Los objetivos del tratamiento del HAP debido a enfermedad suprarrenal unilateral o bilateral incluyen la reversión de los efectos cardiovasculares adversos del hiperaldosteronismo, la normalización del potasio sérico en pacientes con hipopotasemia y la normalización de la presión arterial. El grupo Primary Aldosteronism Surgery Outcome (PASO) publicó un estudio que define los resultados clínicos y bioquímicos en función de la presión arterial y la corrección de la hipopotasemia y los niveles del cociente aldosterona/renina (ARR) para pacientes sometidos a adrenalectomía unilateral total por HAP unilateral. En esta revisión ofrecemos varias recomendaciones prácticas para el manejo y el seguimiento médico-quirúrgico de los pacientes con HAP. (AU)

Hypercalcemic crisis as a presentation of primary hyperparathyroidism / Crisis hipercalcémica como presentación de hiperpara-tiroidismo primario

Abstract Hyperparathyroidism-induced hypercalcemic crisis (HIHC) is an unusual state of marked progressive pri mary hyperparathyroidism (PHPT). Patients have severe hypercalcemia and may have severe symptoms such as kidney failure, acute pancreatitis, and mental changes. PHPT is due to the presence of a single gland adenoma/ disease in 80 to 85%; parathyroid carcinoma is reported in <1%. Among patients with adenoma, atypical parathy roid tumor can be found infrequently. Parathyroidectomy is the only curative approach for PHPT. In this report we present three cases of HIHC due to giant parathyroid adenomas (GPAs), one of them with histopathological characteristics of an atypical parathyroid tumor, with satisfactory evolution after parathyroidectomy.

Resumen La crisis hipercalcémica inducida por hiperparatiroi dismo (HIHC) es un estado inusual de hiperparatiroidis mo primario progresivo y marcado (HPTP). Los pacientes tienen hipercalcemia grave y pueden tener síntomas graves como insuficiencia renal, pancreatitis aguda y cambios mentales. El HPTP se debe a la presencia de un adenoma/enfermedad de una sola glándula en 80 a 85%; el carcinoma de paratiroides se informa en <1%. Entre los pacientes con adenoma, el tumor paratiroideo atípico se puede encontrar con baja frecuencia. La paratiroidec tomía es el único abordaje curativo del HPTP. En este reporte presentamos tres casos de HIHC por adenomas paratiroideos gigantes (APGs), uno de ellos con características histopatológicas de tumor paratiroideo atípico, con evolución satisfactoria luego de paratiroidectomía.

Natal teeth in premature neonates, products of twin gestation. A case report

Se presenta el caso de 02 recién nacidas gemelares, pre-términos tardíos, producto de gestación monocoriónica - biamniótica con presencia de dientes natales, los cuáles requirieron evaluación odontológica para definir la mejor conducta a seguir y con ello evitar riesgos o desenlaces fatales como la aspiración hacia bronquios. La evaluación evidenció escasa movilidad de piezas dentarias en ambos casos, por lo que se recomendó mantener los dientes; del mismo modo, se dio consejería a los padres sobre la higiene y cuidado de la salud bucal de sus hijas con control ambulatorio a los 3 meses.

We present the case of 2 twin newborns, late preterm, who were a product of monochorionic - diamniotic gestation and presented with natal teeth, which required a dental evaluation to define the best management strategy and thereby avoid risks or fatal outcomes such as bronchial aspiration. The evaluation showed little mobility of teeth in both cases, so it was recommended to keep the teeth. The parents were counseled on proper oral health care and hygiene for their daughters and scheduled for an outpatient follow-up at 3 months.

Neoplasia endocrina múltiple tipo 1 en paciente con diagnóstico de nesidioblastosis. Presentación de un caso

Las neoplasias endocrinas múltiples engloban una serie de síndromes caracterizados por su origen genético y la afectación de una o más glándulas. Se describe el caso de un paciente masculino, de 23 años, con antecedentes de salud de nesidioblastosis diagnosticado a los 16 años de edad, quien acudió al Hospital General Docente Ambato por presentar convulsiones tónico clónicas, e hipoglucemia severa con posterior estatus epiléptico. Los estudios de laboratorio mostraron hiperparatiroidismo primario, y los de imagen identificaron lesiones sugerentes de adenoma paratiroideo e insulinoma de cabeza de páncreas. Después de analizar el caso, se identificaron dos criterios para plantear una neoplasia endocrina múltiple tipo 1: presencia de insulinoma e hiperparatiroidismo primario. Además de tratamiento con bifosfonato, se planificó interconsulta con el servicio de Genética, para estudio del paciente y familiares; y con Cirugía General, para programación de resolución quirúrgica. Debido a la poca frecuencia de esta enfermedad, resulta de interés describir el caso, con el objetivo de exponer las principales manifestaciones clínicas y conducta a seguir. Constituye una prioridad el diagnóstico de su causa en cada paciente.

Multiple endocrine neoplasias encompass a series of syndromes characterized by their genetic origin and the involvement of one or more glands. A 23-years-old male patient with a health history of nesidioblastosis diagnosed at 16 years of age, who attended the Ambato General Teaching Hospital with tonic-clonic seizures and severe hypoglycemia with subsequent epileptic status, is described. Laboratory studies showed primary hyperparathyroidism, and imaging identified lesions suggestive of parathyroid adenoma and insulinoma of the head of the pancreas. After analyzing the case, two criteria were identified to suggest multiple endocrine neoplasia type 1: presence of insulinoma and primary hyperparathyroidism. In addition to treatment with bisphosphonate, consultation with the Genetics service was planned for study of the patient and family members; and with General Surgery, for scheduling surgical resolution. Due to the infrequency of this disease, it is of interest to describe the case, with the aim of exposing the main clinical manifestations and conduct to follow. Diagnosing its cause in each patient is a priority.

Encefalitis autoinmune seronegativa asociada a síndrome de Sjögren primario / Autoimmune seronegative encephalitis associated to primary Sjögren's disease

La encefalitis autoinmune es un trastorno inmunomediado que compromete distintos territorios del parénquima cerebral, involucrando frecuentemente la materia gris profunda o la corteza, con o sin compromiso de la materia blanca, meninges o médula espinal. Se asocia frecuentemente con enfermedades autoinmunes o paraneoplásicas, y constituye un reto diagnóstico. Reportamos el caso de una mujer de 55 años con antecedente de síndrome de Sjögren que consultó a Emergencias por cefalea y confusión. El líquido cefalorraquídeo (LCR) presentaba leucocitosis con neutrofilia. En la resonancia magnética nuclear (RMN) cerebral se evidenciaron múltiples imágenes de comportamiento restrictivo, de señal hiperintensa en T2 y FLAIR, a predominio córtico-subcortical a nivel occipital bilateral, hemisferio cerebeloso derecho y parietal derecho. Se descartaron infecciones y neoplasias. El panel de anticuerpos para encefalitis autoinmune aquaporina-4 y anti-MOG en LCR fue negativo. Recibió metilprednisolona endovenosa con mejoría progresiva de los síntomas.

Autoimmune encephalitis is an immune-mediated disorder that affects different areas of the brain parenchyma, often involving deep gray matter or the cortex, with or without involvement of white matter, meninges, or spinal cord. It is frequently associated with autoimmune or paraneoplastic diseases and is a diagnostic challenge. We report the case of a 55-year-old woman with history of Sjögren's syndrome who presented to the emergency department with headache and episodes of confusion. Cerebrospinal fluid (CSF) analysis showed leukocytosis with neutrophilia. Brain MRI revealed multiple restricted diffusion lesions with hyperintense signal on T2 and FLAIR sequences, predominantly in the bilateral occipital region, right cerebellar hemisphere, and right parietal region. Infections and neoplasms were ruled out. The panel of antibodies for autoimmune encephalitis, including Aquaporin-4 and anti-MOG in CSF, was negative. She received intravenous methylprednisolone, leading to symptom improvement.

Primary aldosteronism: Practical recommendations for treatment and follow-up.

Primary aldosteronism (PA) is the most common cause of secondary arterial hypertension. For unilateral cases, surgery offers the possibility of cure, with unilateral adrenalectomy being the treatment of choice, whereas bilateral forms of PA are treated mainly with mineralocorticoid receptor antagonists (MRA). The goals of treatment for PA due to either unilateral or bilateral adrenal disease include reversal of the adverse cardiovascular effects of hyperaldosteronism, normalization of serum potassium in patients with hypokalemia, and normalization of blood pressure. The Primary Aldosteronism Surgery Outcome group (PASO) published a study defining clinical and biochemical outcomes based on blood pressure and correction of hypokalemia and aldosterone to renin ratio (ARR) levels for patients undergoing total unilateral adrenalectomy for unilateral PA. In this review, we provide several practical recommendations for the medical and surgical management and follow-up of patients with PA.

Normocalcemic hyperparathyroidism after successful parathyroidectomy for single parathyroid adenoma: Prevalence, etiological factors, predictive markers, treatment and evolution.

BACKGROUND AND OBJECTIVE: Postparathyroidectomy normocalcemic hyperparathyroidism (PPNCHPPT) is a frequent situation for which we have no information in our country. The objective is to know our prevalence of PPNCHPPT, the associated etiological factors, the predictive markers, the treatment administered and the evolution. PATIENTS AND METHOD: Retrospective observational cross-sectional study on 42 patients. Twelve patients with PPNCHPPT and 30 without PPNCHPPT are compared. RESULTS: HPPTNCPP prevalence: 28.6%. Etiological factors: vitamin D deficiency: 75%; bone remineralization: 16.7%; renal failure: 16.7%; hypercalciruria: 8.3%. No change in the set point of calcium-mediated parathormone (PTH) secretion was observed, but an increase in the preoperative PTH/albumin-corrected calcium (ACC) ratio was observed. Predictive markers: PTH/ACC ratio (AUC 0.947; sensitivity 100%, specificity 78.9%) and PTH (AUC 0.914; sensitivity 100%, specificity 73.7%) one week postparathyroidectomy. EVOLUTION: follow-up 30 ±â€¯16.3 months: 50% normalized PTH and 8.3% had recurrence of hyperparathyroidism. Patients with PPNCHPPT less frequently received preoperative treatment with bisphosphonates and postoperative treatment with calcium salts. CONCLUSIONS: This is the first study in our country that demonstrates a mean prevalence of PPNCHPPT, mainly related to a vitamin D deficiency and a probable resistance to the action of PTH, which can be predicted by the PTH/ACC ratio and PTH a week post-intervention and often evolves normalizing the PTH. We disagree with the etiological effect of hypercalciuria and the change in the PTH/calcemia regulation set point, and we acknowledge the scant treatment administered with calcium salts in the postoperative period.

Manejo conservador con radioterapia e inmunoquimioterapia en el linfoma difuso de células B grandes primario de cuello uterino: Diagnóstico y tratamiento de una entidad rara / Conservative management with radiotherapy and immunochemotherapy in primary diffuse large B-cell lymphoma of the cervix: Diagnosis and treatment of a rare entity

Introducción: El linfoma maligno primario de cuello uterino es una enfermedad muy rara, que representa solo el 0,008% de todos los tumores de cérvix y el 2% de todos los linfomas extraganglionares femeninos.Principales síntomas o hallazgos clínicos: Se presenta el caso de una mujer de 66 años, de los Andes peruanos, con tiempo de enfermedad de 4 meses caracterizado por ginecorragia, con evidencia de cérvix tumoral de 5cm. Se realizó inmunohistoquímica a la biopsia de cérvix para diferencia linfoma del carcinoma epidermoide.Diagnóstico principal: Linfoma difuso de células B grandes primario de cuello uterino con estadificación Ann Arbor IE IPI de bajo riesgo.Intervenciones terapéuticas y resultados: Fue manejada con inmunoquimioterapia (rituximab, ciclofosfamida, adriamicina, vincristina y prednisona), seguida de radioterapia externa consolidativa a dosis de 3.000 cGy en 15 sesiones con técnica especial IMRT. El control de la enfermedad resultó satisfactorio y no presentó complicaciones por la irradiación.Conclusión: El linfoma difuso de células B grandes primario de cuello uterino es muy raro, por lo que, en un caso de lesión primaria del estroma del cérvix, debe tenerse en cuenta la sospecha de linfoma.(AU)

Introduction: Primary malignant cervical lymphoma is a very rare disease, which represents only 0.008% of all cervical tumors and 2% of all female extranodal lymphomas. Main symptoms and/or clinical findings: The case of a 66-year-old woman from the Peruvian Andes is presented, with a disease period of 4 months characterized by gynaecorrhagia, with evidence of a 5cm tumor cervix. Immunohistochemistry was performed on the biopsy of cervix to differentiate lymphoma from squamous cell carcinoma. Primary diagnosis: Primary diffuse large B-cell lymphoma of the cervix with Ann Arbor IE IPI low-risk staging. Therapeutic interventions and results: She being managed with immunochemotherapy (rituximab, cyclophosphamide, adriamycin, vincristine and prednisone), followed by consolidative external radiotherapy at a dose of 3,000cGy in 15 sessions with a special IMRT technique. Resulting in satisfactory disease control and no complications from irradiation.Conclusion: Primary diffuse large B-cell lymphoma of the cervix is very rare, therefore, in a case of primary stromal lesion of the cervix, suspicion of lymphoma should be taken into account.(AU)
