Primary Anti-Phospholipid Antibody Syndrome: Real-World Defining Features of Rethrombosis in the Course of Disease.

Objective: We aimed to identify features that allow differentiation of primary antiphospholipid syndrome (PAPS) patients that suffer recurrent thrombotic events (RTE) despite anticoagulation, from the other diagnosed PAPS patients.

Methods: This was an exploratory study of anticoagulated PAPS patients attending an Autoimmune Diseases Unit (1998-2018). From 2016, anti-phospholipid antibodies and lupus anticoagulant were determined for each patient at consecutive visits, collected together with retrospective clinical characteristics, laboratory, and therapeutic markers and compared according to the occurrence of thrombotic events during follow-up.

Red algae industrial residues as a sustainable carbon platform for the co-production of poly-3-hydroxybutyrate and gluconic acid by .

Polyhydroxyalkanoate (PHA) production using halophilic bacteria has been revisited because less severe operational conditions with respect to sterility can be applied, also alleviating production costs. was selected because it is a moderate halophile able to grow and attain high poly-3-hydroxybutyrate (P3HB) contents under 5-45 g/L NaCl concentrations, conditions that discourage microbial contamination. Industrial residues of the red alga after agar extraction were used as sugar platform to reduce costs associated with the carbon source.

Percutaneous transluminal angioplasty and stenting in acute stroke caused by basilar artery steno-occlusive disease: The experience of a single stroke centre.

Background: Percutaneous transluminal angioplasty and stenting in acute stroke due to severe basilar artery stenosis or basilar artery occlusion remain a matter of debate. The higher risk of stroke recurrence in patients with vertebrobasilar stenosis compared to anterior circulation atherosclerotic disease creates high expectations concerning endovascular approaches. This study aims to review our experience with percutaneous transluminal angioplasty and stenting in acute stroke caused by basilar artery steno-occlusive disease.

Idiopathic Chronic Eosinophilic Pneumonia.

Idiopathic chronic eosinophilic pneumonia (CEP) is a rare disease of unknown cause characterized by eosinophilic alveolar and interstitial infiltration. The authors describe the case of a 46-year-old black man, presenting with insidious onset and progressive course of dyspnea on minimum exertion, cough, fever, night sweats, and weight loss for one year and worsening in the last three months. The main findings were serum eosinophilia.

Catastrophic Gastrointestinal Bleeding: Always Consider Meckel's Diverticulum.

Unlabelled: Meckel's diverticulum, a congenital malformation of the gastrointestinal tract, is asymptomatic in the majority of patients but can be associated with some complications. Gastrointestinal bleeding is one such complication and is more common in children than in adults. Despite the variety of examinations available, diagnosis can be difficult, especially in older patients, because the sensitivity of examinations decreases with patient age.

Rectal ulcer due to Kayexalate deposition - an unusual case.

Sodium polystyrene sulfonate (PSP) or Kayexalate is a cation-exchange resin, widely used in the management of hyperkalaemia due to renal disease. A rare, yet potentially dangerous, adverse event related to sodium polystyrene sulfonate use is intestinal mucosal injury, especially in the colon. The injury to the gastrointestinal mucosa can range from mild and superficial to wall necrosis and bowel perforation.

Vasculitis of small and large vessels, a casual association?

The authors report a case of a 69-year-old man with idiopathic leukocytoclastic cutaneous vasculitis. For three years, the lesions recurred with progressive worsening and were associated with systemic manifestations of low-grade fever, weight loss and raised inflammatory markers. The patient latter presented a 6th cranial nerve involvement, raising the concern of a possible systemic vasculitis, which was latter evidenced by the development of deep vein thrombosis and angina pectoris.
