Antecedentes y objetivo: La asociación de hipouricemia e hipercalciuria es poco frecuente. En 1974 se describió un nuevo síndrome nominado Hipouricemia con hipercalciuria y reducción de la densidad ósea. Posteriormente, se publicaron algunos casos con esa asociación en los que la excreción fraccional de urato era superior a 20/100ml FGR. Hemos analizado una serie de niños que fueron diagnosticados de hipouricemia e hipercalciuria y que fueron controlados evolutivamente. El objetivo del trabajo es intentar conocer si nuestros pacientes podrían estar afectos del síndrome antes mencionado o ser portadores de una variante de hipercalciuria idiopática. Pacientes y métodos: Estudio retrospectivo longitudinal en el que se estudiaron las historias clínicas de 8 pacientes (5V y 3M) diagnosticados de hipouricemia e hipercalciuria en la infancia. Se anotaron la clínica al diagnóstico, los hallazgos ecográficos y densitométricos, y determinadas variables bioquímicas, con especial hincapié en el manejo tubular renal del urato. Los resultados se compararon con los de 36 niños afectos de hipercalciuria idiopática sin hipouricemia (14V y 22M). Resultados: En el grupo con hipouricemia los niveles iniciales de uricemia fueron 1,9 (0,3) mg/dl (rango: 1,5-2) y los del cociente calcio/creatinina en primera orina del día, 0,27 (0,05) mg/mg (rango: 0,23-0,31). En todos los casos la excreción fraccional de urato fue inferior a 20ml/100ml FGR. Los valores de z-DMO fueron menores de −1 en 4/8 casos. En el último control, solo en 3 casos persistía el cociente calcio/creatinina elevado, y en todos la uricemia era superior a 2mg/dl. El valor de z-DMO había mejorado en 5 casos y empeorado en otros 3... (AU)
Background and objective: The association of hypouricemia and hypercalciuria is rare. In 1974 a new syndrome named Hypouricemia with hypercalciuria and decreased bone density was described. Afterwards, some cases with such association were published in which the fractional excretion of urate was higher than 20/100ml FGR. We have analyzed a series of children who were diagnosed with hypouricemia and hypercalciuria and who were monitored. The aim of this study was to determine whether our patients could be affected by the aforementioned syndrome or be carriers of a variant of idiopathic hypercalciuria. Patients and methods: Retrospective longitudinal study in which the medical records of eight patients (5V and 3M) diagnosed with hypouricemia and hypercalciuria in childhood. Clinical features at diagnosis, ultrasound and densitometric findings and selected biochemical variables were noted, with special emphasis on renal tubular handling of urate. Results were compared with 36 children with idiopathic hypercalciuria without hypouricemia (14V and 22M). Results: In the hypouricemia group baseline urate levels were 1.9 (0.3)mg/dl (range: 1.5-2) and first day urine calcium/creatinine ratio 0.27 (0.05)mg/mg (range: 0.23-0.31). In all cases fractional urate excretion was less than 20/100ml FGR. The z-DMO values were less than −1 in 4/8 cases. At the last follow-up only three cases still had an elevated calcium/creatinine ratio and in all of them the urates levels was greater than 2mg/dl. The z-DMO value had improved in five cases and worsened in three others. In relation to the group without hypouricemia, no differences were observed between the various parameters studied including the z-DMO value, with the exception of fractional excretion and tubular urate reabsorption although plasmatic uric acid levels were still significantly lower...

Objective. To study the diagnostic performance of an ultrasound-based algorithm that includes the deceleration time (DT) of early mitral filling to establish a diagnosis of acute heart failure (AHF) in patients who come to an emergency department because of dyspnea. Methods. Prospective analysis in a convenience sample of patients who came to a hospital emergency department with acute dyspnea. The algorithm included ultrasound findings and 4 echocardiographic findings as follows: mitral annular plane systolic excursion, Doppler mitral flow velocity, tissue Doppler imaging measure of the lateral annulus, and the DT of early mitral filling. The definitive diagnosis was made by 2 physicians blinded to each others diagnosis and the ultrasound findings. Results. A total of 166 adult patients with a mean (SD) age of 76 (13) years were included; 79 (48%) were women. AHF was the definitive diagnosis in 62 patients (37%). Diagnostic agreement was good between the 2 physicians (κ = 0.71). The algorithm classified all the patients, and there were no undetermined diagnoses. Diagnostic performance indicators for the ultrasound-based algorithm integrating early DT findings were as follows: area under the receiver operating characteristic curve, 0.91 (95% CI, 0.86-0.96); sensitivity, 87% (95% CI, 76%-94%); specificity, 95% (95% CI, 89%-98%); positive likelihood ratio, 18.1 (95% CI, 7.7-42.8); and negative likelihood ratio, 0.14 (95% CI, 0.07-0.26). Conclusions. The ultrasound-based algorithm integrating the DT of early mitral filling performs well for diagnosing AHF in emergency patients with dyspnea. The inclusion of early DT allows all patients to be diagnosed. (AU)

Introducción y objetivos: Los objetivos son analizar la relación dosis-respuesta de la rigidez de la arteria carótida y la mortalidad y evaluar su capacidad predictiva. Métodos: Estudio de cohorte poblacional que incluyó a 6.468 participantes, con una mediana de seguimiento de 6,5 años. Se evaluaron 6 índices de rigidez. Se identificaron los eventos coronarios y cerebrovasculares y la mortalidad. Resultados: La rigidez carotídea, el coeficiente de Peterson y la velocidad de la onda de pulso (VOP) se asociaron de manera lineal y directa con los eventos cerebrovasculares: aumento del 8% (IC95%, 1-16%) por unidad de rigidez, del 7% (IC95%, 2-13%) cada 10 unidades del coeficiente de Peterson y del 26% (IC95%, 8-48%) por unidad de la VOP. La tensión carotídea se asoció de modo no lineal con el riesgo de enfermedad coronaria: en valores <0,09 unidades, cada aumento de 0,01 unidades se asoció con una disminución de un 16% del riesgo (IC95%, 33 a +6%); por encima de 0,09 unidades, cada incremento de 0,01 unidades se asoció con un aumento de un 16% del riesgo (IC95%, 6-27%). La inclusión de estos índices no mejoró la capacidad predictiva de las funciones de riesgo. Conclusiones: La rigidez carotídea, el coeficiente de elasticidad de Peterson y la VOP tienen una relación lineal y directa con el riesgo de enfermedad cerebrovascular. La tensión (strain) carotídea tiene una relación en U con el riesgo de enfermedad coronaria. Estos índices no contribuyen a mejorar la capacidad predictiva de las funciones de riesgo. (AU)
Introduction and objectives: The aims of this study were to determine the dose-response association of carotid arterial stiffness with vascular outcomes and overall mortality, and to assess their added predictive capacity. Methods: Population-based cohort study including 6468 individuals, with a median follow-up of 6.5 years. Six carotid artery stiffness indices were assessed: strain, stiffness, Peterson elasticity coefficient, compliance coefficient, distensibility coefficient, and pulse wave velocity (PWV). Incident coronary, cerebrovascular, global vascular, and total fatal events were identified. Results: Carotid compliance and distensibility coefficients were not associated with any of the outcomes. Carotid stiffness, Peterson elasticity coefficient, and PWV showed a direct linear relationship to cerebrovascular disease: the risk increased by 8% (95%CI, 1-16) per stiffness unit increase, by 7% (95%CI, 2-13) per 10-unit Peterson elasticity coefficient increase, and by 26% (95%CI, 8-48) per PWV unit increase. Carotid strain showed a nonlinear association with ischemic heart disease. When strain was ≤ 0.09 units, each 0.01-unit increase was associated with a 15% lower risk of coronary events (95%CI,−33 to 6); above 0.09 units, each 0.01 increase in strain was associated with a 16% higher risk of coronary events (95%CI, 6-27). The addition of the stiffness indices did not improve the predictive capacity of validated risk functions. Conclusions: Carotid stiffness, Peterson elasticity coefficient, and PWV have a direct linear association with cerebrovascular disease risk. Carotid strain is not linearly related to U-shaped ischemic heart disease risk. The inclusion of these indexes does not improve the predictive capacity of risk functions. (AU)

Background: Around 10% of people report a drug allergy and avoid some medications because of fear of allergic reactions. However, only after a proper diagnostic workup can some of these reactions be confirmed as allergic or nonallergic hypersensitivities. Beta-lactams (BLs) are the most common medication suspected of being involved in drug hypersensivity reactions (DHRs) in children. Recently, direct oral provocation tests (DPT) with BLs gained popularity within pediatric populations as a tool for delabeling children with suspected BL allergies. This study aimed to evaluate the safety of direct provocation tests in infants with mild cutaneous non-immediate reactions to BLs. Methods: The authors retrospectively analyzed the data of 151 infants between 2015 and 2022, referred for evaluating a suspected allergy to BLs that occurred before age 24 months. Results: The mean age of the children, including 55% male kids, at the suspected reaction was 15.9 months and the mean age at the time of the DPT was 39.6 months. In most cases, antibiotics were prescribed to treat common upper respiratory infections, such as acute otitis (54.3%) and acute tonsillitis (27.2%). Amoxicillin was considered the culprit drug in 62.9% of the cases, and the combination of amoxicillinclavulanic acid in the case of 33.8% of children. The most frequent associated cutaneous clinical manifestations were maculopapular exanthema in 74.8% and delayed urticaria/angioedema in 25.2%. Of the 151 infants evaluated, parents of 149 infants agreed for a direct DPT, and only three had a positive test (2%). Symptoms resulting from the DPT were mild and easily treatable. Conclusions: A direct DPT without prior tests is a safe and effective procedure to delabel BL allergy, even in infants... (AU)

Background: The differentiation between primary and metastatic salivary gland neoplasms (SGNs) helps in determining appropriate management strategies, including the need for additional diagnostic tests, surveillance, or aggressive treatment. The purpose of this study was to identify and quantify the immature and mature dendritic cells (DCs) in metastatic and no metastatic SGNs and determine its association with clinicopathological findings. Material and Methods: Cross-sectional, observational, and descriptive study that includes 33 malignant salivary gland neoplasms [MSGN (6, 18.1% metastatic)], and 22 pleomorphic adenomas (PA), as a control group. Clinical and histopathological characteristics were obtained. Immunohistochemistry for human leukocyte antigen Drelated (HLA-DR), CD1a, CD83, and Ki-67 proteins was done. Positive intra- and peritumoral DCs were counted. Results: Individuals with MSGN had a lower density of intratumoral HLA-DR+ cells than those with PA (p=0.001), Ki-67 immunostaining was significantly higher in MSGN than in PA (6% vs. 1.4%, p<0.001). Metastatic MSGN showed less intratumoral CD1a+ than non-metastatic (3.2 vs. 165.1, p=0.001). No differences in intra- and peritumoral CD83+ cells were found between benign and malignant SGN. Conclusions: These results suggest that the immune-protective function of intratumoral DCs is compromised in MSGNs. DCs markers may represent useful prediction tools for metastases in salivary gland malignancies, with crucial implications in the implementation of appropriate disease management strategies. (AU)

La hidatidosis es una zoonosis poco frecuente causada por cestodos del género Echinococcus. El órgano afectado con mayor frecuencia es el hígado, seguido del pulmón. La hidatidosis pulmonar se caracteriza por cursar de forma asintomática en la mayoría de los casos, y en muchas ocasiones suele ser un hallazgo casual en estudios realizados con otros fines. El diagnóstico resulta complejo por la diversidad de la presentación clínica, las pruebas serológicas pueden resultar negativas y los hallazgos de laboratorio son inespecíficos, por lo que debería ser un diagnóstico a tener en cuenta sobre todo en zonas con alta prevalencia de esta infestación. (AU)
Hydatidosis is a rare zoonosis caused by cestodes of the genus Echinococcus. The most frequently affected organ is the liver, followed by the lung. Pulmonary hydatidosis is characterized by an asymptomatic course in most cases, and in many cases it is usually an incidental finding in studies performed for other purposes. The diagnosis is complex due to the diversity of the clinical presentation, serological tests can be negative and laboratory findings are nonspecific, so it should be a diagnosis to consider especially in areas with high prevalence of this infestation.

In recent years, there has been a lot of research interest in the growing use of artificial intelligence (AI) in health and medicine. This study attempts to provide a global, verified picture of research on AI in medicine and health. There are vast informational resources available, but there are also devices that can't decide examples precisely or predict the future. The conventional methods for diagnosing illnesses are manual and prone to error. When compared to elite human ability, the use of artificial intelligence's predictive approaches improves auto determination and reduces identification errors. A thorough analysis of those articles convinced the ordering party to order the most complex AI processes for clinical symptomatic frameworks. This research report seeks to unearth some key information on the flow and pastof many AI techniques in the clinical setting used in the current clinical investigation, particularly in the areas of coronary disease prediction, brain illness, prostate, liver illness, and kidney infection. In order to ensure that Childs are well-informed and guided, this study uses the coordination examination calculation to distinguish Childs' mental health difficulties and applies the reconciliation examination calculation to Childs' mental health inquiry. A thorough analysis and exploration of children's mental health is completed in light of the framework design approach and information mining grouping technique. (AU)

Kairos has been a key concept in medicine for millennia and is frequently understood as "the right time" in relation to treatment. In this study we scrutinize kairos in the context of diagnostics. This has become highly topical as technological developments have caused diagnostics to be performed ever earlier in the disease development. Detecting risk factors, precursors, and predictors of disease (in biomarkers, pre-disease, and pre-pre-disease) has resulted in too early diagnoses, i.e., overdiagnoses. Nonetheless, despite vast advances in science and technology, diagnoses also come too late. Accordingly, timing diagnostics right is crucial. In this article we start with giving a brief overview of the etymology and general use of the concepts of kairos and diagnosis. Then we delimit kairos in diagnostics by analysing "too early" and "too late" diagnosis and by scrutinizing various phases of diagnostics. This leads us to define kairos of diagnostics as the time when there is potential for sufficient information for making a diagnosis that is most helpful for the person. It allows us to conclude that kairos is as important in diagnostics as in therapeutics.
