[Chronic ischemic gastropathy as a simulator of plastic linitis]. / Gastropatía isquémica crónica como simuladora de linitis plástica.

Chronic ischemic gastropathy is a rare entity, being the atheroesclerotic vascular the most prevalent cause. Clinical and endoscopic manifestations are unspecific and may simulate more frequent pathologies. Cardiovascular risk factors allow us to diagnose and treat these patients earlier. We present the case of a patient with chronic ischemic gastropathy that manifested abdominal pain, weight loss and endoscopic findings as a simulator of linitis plastica. The diagnosis was made with an endoscopic block biopsy after two inconclusive biopsies.

Sus manifestaciones clínicas y endoscópicas son inespecíficas, pudiendo simular afecciones más prevalentes. La sospecha clínica en pacientes con factores de riesgo cardiovascular permite un diagnóstico precoz y tratamiento adecuado. Presentamos el caso de una paciente con gastropatía isquémica crónica que se manifestó con dolor abdominal, pérdida de peso y hallazgos endoscópicos compatibles con linitis plástica.

Abstract Chronic ischemic gastropathy is a rare entity, being the atheroesclerotic vascular the most prevalent cause. Clinical and endoscopic manifestations are unspecific and may simulate more frequent pathologies. Cardio vascular risk factors allow us to diagnose and treat these patients earlier. We present the case of a patient with chronic ischemic gastropathy that manifested abdominal pain, weight loss and endoscopic findings as a simula tor of linitis plastica. The diagnosis was made with an endoscopic block biopsy after two inconclusive biopsies.

[Toxic epidermal necrolysis: idiosyncratic reaction to drugs]. / Necrólisis epidérmica tóxica: reacción idiosincrática a neurofármacos.

Toxic epidermal necrolysis (NET) and Steven Johnson syndrome (SJS) are infrequent mucocutaneous hypersensitivity reactions with systemic involvement. They are predominantly caused by drugs. We report the case of a patient over 60 years of age who presented with extensive mucocutaneous and ophthalmic injury with hemodynamic failure, associated with the rapid onset of lamotrigine in a short period of time. Although the incidence is low, the mortality rate is high. It requires early suspicious and diagnosis in addition to an interdisciplinary therapeutic approach.

Adverse outcome of early recurrent ischemic stroke secondary to atrial fibrillation after repeated systemic thrombolysis.

Background. Recurrent ischemic stroke is associated with adverse neurological outcome in patients with atrial fibrillation. There is very scarce information regarding the neurological outcome of atrial fibrillation patients undergoing repeated systemic thrombolysis after early recurrent ischemic stroke. Clinical Case and Discussion. We describe a case of a 76-year-old woman with known paroxysmal atrial fibrillation who was admitted because of an acute right middle cerebral artery ischemic stroke and who underwent repeated systemic thrombolysis within 110 hours. The patient underwent systemic thrombolysis after the first ischemic stroke with almost complete neurological recovery. On the fourth day after treatment, an acute left middle cerebral artery ischemic stroke was diagnosed and she was treated with full-dose intravenous recombinant tissue plasminogen activator. A hemorrhagic transformation of the left middle cerebral artery infarction was noted on follow-up cranial computed tomographic scans. The patient did not recover from the second cerebrovascular event and died 25 days after admission. Conclusion. To the best of our knowledge, this is the second case reporting the adverse neurological outcome of a patient with diagnosis of atrial fibrillation undergoing repeated systemic thrombolysis after early recurrent ischemic stroke. Our report represents a contribution to the scarce available evidence suggesting that repeated systemic thrombolysis for recurrent ischemic stroke should be avoided.

[Congenital hypothyroidism secondary to thyroid hypoplasia detected in adulthood]. / Hipotiroidismo congénito secundario a hipoplasia tiroidea detectado en edad adulta.

The anatomical location of the thyroid gland and its hormone byosinthesis are regulated by the expression of certain genes, whose disruption leads to the so-called thyroid dysgenesis: agenesis, ectopia and hypoplasia, and to dyshormonogenesis. We present the case of a patient with mental retardation and hypothyroidism whose diagnosis was made in adulthood. Biochemical determinations confirmed the diagnosis without evidence of thyroid autoimmunity. This patient represents the extended evolution of a thyroid hypofunction, which lasted in an unsuspected way for 53 years, with important consequences of this deficiency at diagnosis. Exogenous therapy achieved great improvement in clinical symptoms, but did not reverse the neurological damage attributable to the lack of thyroid hormone necessary for fetal development. The necropsy revealed little thyroid tissue in the neck corresponding to eutopic thyroid hypoplasia. The discovery of a remaining thyroid of less than 1 cm justified the patient survival up to old age.

Hipotiroidismo congénito secundario a hipoplasia tiroidea detectado en edad adulta / Congenital hypothyroidism secondary to thyroid hypoplasia detected in adulthood

La ubicación anatómica de la glándula tiroidea y su biosíntesis hormonal están reguladas por la expresión de ciertos genes, cuya alteración puede conducir a las denominadas disgenesias tiroideas: agenesia, ectopía e hipoplasia, así como a las variantes dishormonogenéticas. Se presenta el caso de una paciente con retraso mental y diagnóstico de hipotiroidismo realizado en la edad adulta. Las determinaciones bioquímicas confirmaron el diagnóstico de hipotiroidismo no autoinmune. Este caso representa la evolución prolongada de una hipofunción tiroidea, que cursó en forma solapada y no diagnosticada durante 53 años de vida, con secuelas relevantes de esta deficiencia al momento del diagnóstico. La terapia exógena logró mejorías evidentes en la signo sintomatología, pero no revirtió el presunto daño neurológico atribuible a la falta de hormona tiroidea necesaria durante el desarrollo fetal. En la necropsia realizada se encontró escaso tejido tiroideo cervical correspondiente a hipoplasia tiroidea eutópica. El hallazgo de un remanente tiroideo menor a 1 cm permite explicar la supervivencia de la paciente hasta una edad avanzada.
