ABSTRACT
Self-cleaning and self-sanitizing coatings are of utmost interest in several manufacturing domains. In particular, fabrics and textile materials are often pre-treated by impregnation or incorporation with antimicrobial pesticides for protection purposes against bacteria and fungi that are pathogenic for man or other animals. In this respect, the present investigation deals with the design and manufacture of self-cleaning and self-sanitizing coatings on plastic fabrics. The functionalization of the coatings was yield by incorporating active inorganic matter alone (i.e., photo-catalytic TiO2 anatase and Ag(+) ions) inside an organic inorganic hybrid binder. The achieved formulations were deposited on coextruded polyvinylchloride-polyester fabrics by air-mix spraying and left to dry at ambient temperature. The performance of the resulting coatings were characterized for their self-cleaning and self-sanitizing ability according to standardized testing procedure and/or applicable international regulations.

A young patient with undefined autoimmune lymphoproliferative syndrome (ALPS-U) and low back pain underwent a CT and MRI study that showed enhancing vertebral lesions, some pulmonary nodules and diffuse latero-cervical lymphadenopathy. A 18F-FDG-PET/CT scan showed many areas of intense 18F-FDG uptake in multiple vertebrae, in some ribs, in the sacrum, in the liver, in both lungs, in multiple lymph nodes spread in the cervical, thoracic and abdominal chains. A bone marrow biopsy showed a "lymphomatoid granulomatosis", a rare variant of B-cell non-Hodgkin lymphoma (NHL). After the treatment, the 18F-FDG-PET/CT scan showed a complete metabolic response (AU)
Un paciente joven con síndrome linfoproliferativo autoinmune indefinido (ALPS-U) y dolor lumbar se sometió a una tomografía computarizada y a una resonancia magnética, estudios que mostraron varias lesiones vertebrales, algunos nódulos pulmonares y adenopatías laterocervicales difusas. Una exploración 18F-FDG-PET/TC reveló áreas de captación intensa de 18F-FDG en múltiples vértebras, algunas costillas, sacro, hígado, ambos pulmones y en varios ganglios linfáticos repartidos en las cadenas cervicales, torácica y abdominal. La biopsia de médula ósea diagnosticó una granulomatosis linfomatoide, una variante poco frecuente de Linfoma no-Hodgkin de células B (LNH). Tras el tratamiento, la exploración 18F-FDG-PET/TC demostró una respuesta metabólica completa (AU)

A young patient with undefined autoimmune lymphoproliferative syndrome (ALPS-U) and low back pain underwent a CT and MRI study that showed enhancing vertebral lesions, some pulmonary nodules and diffuse latero-cervical lymphadenopathy. A (18)F-FDG-PET/CT scan showed many areas of intense (18)F-FDG uptake in multiple vertebrae, in some ribs, in the sacrum, in the liver, in both lungs, in multiple lymph nodes spread in the cervical, thoracic and abdominal chains. A bone marrow biopsy showed a "lymphomatoid granulomatosis", a rare variant of B-cell non-Hodgkin lymphoma (NHL). After the treatment, the (18)F-FDG-PET/CT scan showed a complete metabolic response.

OBJECTIVE: To examine whether patients with Eating Disorders (ED) who restore menses differ from those who remain amenorrheic after treatment and to provide longitudinal data about this debated criterion of Anorexia Nervosa (AN). METHODS: 184 outpatients were recruited: 50 patients with AN Restrictive type, 75 amenorrheic Eating Disorder Not Otherwise Specified (EDNOS) patients, 24 patients who recovered from AN with persistent amenorrhea, and 35 amenorrheic patients without ED. All participants were clinically assessed by psychiatrists and gynaecologists at the beginning of treatment and at the one-year follow-up. They also completed several psychometric tests: Eating Disorder Inventory-2, Temperament and Character Inventory, and Beck Depression Inventory. RESULTS: After treatment, a large portion of the sample resumed menses but very few recovered completely from the ED. No psychopathological variables could clearly predict the recovery of menses in the different groups. However, Body Mass Index and some biological variables were associated with restoration of menses in ED patients. CONCLUSION: Resumption of menses was not associated with a less severe eating symptomatology at the beginning of treatment nor with unequivocal psychopathological changes after treatment. It is important that clinicians consider not only the presence or absence of regular menses but also that they improve both ED screening and assessment in amenorrheic patients. Amenorrhea does not seem to represent a specific predictor of severity of illness or to show prognostic value.
