[Non-invasive diagnosis of cardiac amyloidosis due to transthyretin. Case report]. / Diagnóstico no invasivo de amiloidosis cardiaca por transtirretina. Caso clínico.

Amyloidosis due to deposits of transthyretin (ATTR) is currently considered the most frequent form of cardiac amyloidosis and its incidence is increasing thanks to the advances in diagnostic imaging techniques. Some non-invasive diagnostic criteria have recently been published on this entity that due to the development of new drugs for the specific treatment of cardiac ATTR, have prognostic and therapeutic implications. That is why cardiac ATTR could cease to be a rare disease and become a frequent one, and become potentially treatable instead of incurable. We present the case of an 80-year-old male diagnosed with non-hereditary cardiac ATTR by means of gammagraphy with 99mTc diphosfonate scintigraphy (99mTc-DPD) following the new criteria of non-invasive diagnosis.

[Varicella pneumonia in previously healthy adults]. / Neumonitis varicelosa en el adulto previamente sano.

Two cases of pneumonia associated with chicken pox in previously healthy patients are described. Their known risk factor was heavy smoking. Both were treated successfully with parenteral aciclovir, although one presented a restrictive spirometric pattern with lowered DLCO that became normal 3 months after discharge.

[Acute respiratory insufficiency secondary to Coxiella burnetii pneumonia: a rare complication]. / Insuficiencia respiratoria aguda secundaria a neumonía por Coxiella burnetii: una complicación excepcional.

Acute respiratory failure secondary to Coxiella burnetii infection is an extremely rare but serious complication that usually has a good prognosis after appropriate treatment. We describe a female patient who developed acute respiratory failure secondary to Coxiella burnetii pneumonia requiring mechanical ventilation and antibiotic therapy.

[Pheochromocytoma secreting adrenaline, a rare form of presentation]. / Feocromocitoma secretor de adrenalina, como forma excepcional de presentación.

We present the case of a 42-year-old patient with a pheochromocytoma, whose clinical form of presentation was extremely rare, due to the high secretion of adrenalin compared to noradrenaline. We stress the relevance of the anamnesis for the diagnosis of this pathology, as well as the problems regarding its clinical, anaesthetic and surgical management. In addition, we review the literature.

[Tracheobronchopathia osteochondroplastica . Apropos a case]. / Traqueobroncopatía osteocondroplástica. A propósito de un caso.

We present one case of osteochondroplastic tracheobronchopathy in a patient with right laterocervical tumoration as a manifestation of a normofunctional nodular goiter detected in a thyroid morphofunctional study, and tracheal stenosis secondary both to the goiter and the tracheobronchial process. The coincidence of these two processes, probably fortuitous, has never been described before.
