Pseudoartrosis congénita bilateral de la clavícula: a propósito de un caso familiar

Presentamos una paciente de nueve meses con pseudoartrosis congénita bilateral de ambas clavículas, cuya madre presenta el mismo cuadro. Dicho cuadro es una entidad rara, pobremente documentada en la ortopedia pediátrica. La etiología y patogenia aún permanece oscura. La apariencia clínico-radiológica consiste en la ausencia desde el nacimiento de un defecto de unión a nivel del tercio medio clavicular característico. El diagnóstico diferencial debe hacerse con las fracturas perinatales, pseudoartrosis postraumáticas y disostosis cleido-craneales.The case of a female patient of nine months of are and her mother, 41-year-old showing a Congenital Bilateral Pseudoarthrosis of the clavicle are presented. This is a rare entity that has been poorly documented in paediatrics orthopedics literature. The etiology and pathogenesis still remain unclear. The clinical and radiological appearance are characteristic. Differential diagnosis lies between postpartum fractures, postraumatic pseudoarthrosis, and cleidocraneal dysostosis

Osteopoiquilosis y síndrome de Buschke-Ollendörf: a propósito de un caso

Presentamos una paciente de 22 años que tras estudios radiológicos rutinarios, muestra una displasia ósea condensante, completamente asintomática e inócua, que afectaba principalmente pelvis y extremidades distales, mientras que las costillas, cráneo y columna dorsolumbar estaban indemnes. Asimismo, aparecen nevus elásticos y fibromas en la piel. Esta entidad no puede confundirse con un carcinoma metastásico esclerosante, esclerosis tuberosa u otras displasias como la melorreostosis.A female patient, 22 years oíd, showing characteristic sclerotic bone images on radiographic examinations is reported. The main locations were on the distal limbs and pelvis. She has also elastic nevi as freckles in the skin. This entity was not stablished as inhered process. The differential diagnosis lies between sclerotic metastasis, neurofibromatosis (Von Recklinghausen), Bourneville disease and other displastyc lesions

Síndrome compartimental en joven con alteración hemática

El síndrome compartimental es una patología bien conocida que se produce por un aumento de la presión dentro de un compartimiento miofascial. Presentamos el caso de un paciente con trombopenia que sufrió un traumatismo banal. Necesitó fasciotomía del compartimiento anteroexterno de la pierna y, más tarde, esplenectomía. El diagnóstico y tratamiento tardíos de esta complicación, así como una descomprensión inadecuada, pueden conducir a la pérdida de función en una extremidad.The compartment syndrome is a well described cli- nical entity that results from increased pressure within a myo- fascial compartment. An unusual case of a patient with thrombopenia and a minimal traumatism, is reported. He required fasciotomy of the anterolateral compartment of the leg and, later, splenectomy. Late recognition and treatment of this complication, as well as inadequate decompression, can lead to loss of limb

Circulating Cell Biomarkers in Pulmonary Arterial Hypertension: Relationship with Clinical Heterogeneity and Therapeutic Response

In this study, we simultaneously analysed circulating levels of endothelial microvesicles (EMVs) and progenitor cells (PCs) in PAH and in controls, as biomarkers of pulmonary endothelial integrity and evaluated differences among PAH subtypes and as a response to treatment. Methods: Forty-seven controls and 144 patients with PAH (52 idiopathic, 9 heritable, 31 associated with systemic sclerosis, 15 associated with other connective tissue diseases, 20 associated with HIV and 17 associated with portal hypertension) were evaluated. Forty-four patients with scleroderma and 22 with HIV infection, but without PAH, were also studied. Circulating levels of EMVs, total (CD31+CD42b−) and activated (CD31+CD42b−CD62E+), as well as circulating PCs (CD34+CD133+CD45low) were measured by flow cytometry and the EMVs/PCs ratio was computed. In treatment-naïve patients, measurements were repeated after 3 months of PAH therapy. Results: Patients with PAH showed higher numbers of EMVs and a lower percentage of PCs, compared with healthy controls. The EMV/PC ratio was increased in PAH patients, and in patients with SSc or HIV without PAH. After starting PAH therapy, individual changes in EMVs and PCs were variable, without significant differences being observed as a group. Conclusion: PAH patients present disturbed vascular homeostasis, reflected in changes in circulating EMV and PC levels, which are not restored with PAH targeted therapy. Combined measurement of circulating EMVs and PCs could be foreseen as a potential biomarker of endothelial dysfunction in PAH.This research was funded by grants PI12/00510, PI15/00582 and PI18/00960 from the Institute of Health Carlos III (ISCiii), Spain, co-funded by the European Union (ERDF/ESF); the Catalan Society of Respiratory Medicine (SOCAP); and the Fundación Contra la Hipertensión Pulmonar (FCHP).

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio

Management of eosinophilassociated inflammatory diseases: the importance of a multidisciplinary approach

Elevated eosinophil counts in blood and tissue are a feature of many pathological processes. Eosinophils can migrate and accumulate in a wide variety of tissues and, by infiltrating a target organ, can mediate the development of several inflammatory diseases. The normalization of eosinophilia is a common biomarker of a treatable trait and can also be used as a prognostic and predictive biomarker since it implies a reduction in type 2 inflammation that contributes to disease pathogenesis. Biological therapies targeting this cell type and its proinflammatory mediators have been shown to be effective in the management of a number of eosinophilic diseases, and for this reason they constitute a potential common strategy in the treatment of patients with various multimorbidities that present with type 2 inflammation. Various biological options are available that could be used to simultaneously treat multiple target organs with a single drug, bearing in mind the need to offer personalized treatments under the umbrella of precision medicine in all patients with eosinophil-associated diseases (EADs). In addition to reviewing these issues, we also discuss a series of perspectives addressing the management of EAD patients from a multidisciplinary approach, with the collaboration of health professionals from different specialties who manage the different multimorbidities that frequently occur in these patients. We examine the basic principles of care that this multidisciplinary approach must cover and present a multidisciplinary expert opinion regarding the ideal management of patients with EADs, from diagnosis to therapeutic approach and follow-u
