La cova de s'Abisament

[cat] Presentam una cavitat litoral de la zona de mescla, excavada en els materials escullosos del Miocè superior del Llevant de Mallorca. Constitueix un exemple més de la importància que tenen les oscil·lacions glacioeustàtiques en l’evolució de l’endocarst litoral. L’evolució progressiva l’ha convertida en una sala d’esfondrament, amb tots els contorns de la cova delimitats per productes dels enderrocs. Les morfologies de corrosió, situades per davall del començament de l’haloclina, han afectat part dels productes de l’esbucament, així com sostres i parets. Els espeleotemes més interessants corresponen a paleonivells freàtics ubicats a la cota de -11,5 m. La columna hídrica presenta dues masses d’aigua molt diferenciades, una primera capa fins als 7 m, amb una salinitat de l’ordre del 2‰ al 4‰ i una segona capa fins als 12 m a on la salinitat puja contínuament fins assolir valors de 31‰ a la cota més profunda de la cavitat. S’han determinat un total de sis espècies de crustacis estigobionts que tenen el seu preferent, o bé que toleren, les zones d’aigües de menor salinitat.[eng] We present a coastal cave in the mixing zone, excavated in shelly material from the Upper Miocene on the Llevant de Mallorca. It constitutes another example of the importance that glacioeustatic osillations have on the evolution of the coastal endokarst. Its progressive evolution has turned it into a breakdown chamber, with the contour of the cave delimited by rock falls. The corrosion morphologies, situated in the halocline zone, have affected part of the fallen materials, likewise roofs and walls. The the most interesting speleothems are found at phreatic paleolevels now at -11.5 m. The water column shows two very different masses of water, a first layer down to 7 m, with a salinity between 2 and 4‰, and a second one down to 12 m where the salinity increases progressively to 31‰ in the deepest reaches. A total of six stygobiont crustaceans have been classified which prefer, or at least tolarate, zones of water with lower salinity

Organizing pneumonia in a patient with hodgkin's lymphoma and large B cell lymphoma: a rare association

Organizing Pneumonia (OP) is classified as an Idiopathic Interstitial Pneumonia (IIP).1 Clinically, the patients present dyspnea, cough, and low fever, and usually respond well to corticosteroids, reaching clinical and radiologic resolution in a short timeframe. However, sometimes infiltrates do recur and may not resolve. Radiologically, migratory consolidations are identified in high-resolution computed tomography (HRCT), sometimes associated with progressive fibrosis with reticulation and areas of persistent consolidation.1 The histology reveals “proliferation of fibroblastic tissue within small airways, alveolar ducts, and alveolar spaces”.2 OP can be secondary to other pathologies such as common variable immunodeficiency3 and malignant disease among others.4 At times no etiology is identified and the term Cryptogenic Organizing Pneumonia (COP) is used.1 Furthermore, OP could coexist or mimic a malignant disease.4,
