RESUMEN
AIM: To evaluate the use of health care resources and the associated costs of complex perianal Crohn's disease (CD) from the National Health System perspective. METHODS: We conducted a multicenter, retrospective, observational study in which gastroenterologists from 11 hospitals in the Community of Madrid took part. Data was collected on the direct healthcare resources (pharmacological treatments, surgical procedures, laboratory/diagnostic tests, visits to specialists and emergency departments, and hospitalizations) consumed by 97 adult patients with complex perianal CD which was active at some point between January 1, 2005, and case history review. RESULTS: We recorded 527 treatments: 73.1% pharmacological (32.3% antibiotic, 20.5% immunomodulator, 20.3% biological) and 26.9% surgical. Mean annual global cost was 8,289/patient, 75.3% (6,242) of which was accounted for by pharmacological treatments (13.44 antibiotics; 1,136 immunomodulators; 5,093 biological agents), 12.4% (1,027) by hospitalizations and surgery, 7.7% (640) by medical visits, 4.2% (350) by laboratory/diagnostic tests, and 0.4% (30) by emergency department visits. CONCLUSIONS: Pharmacological therapies, and in particular biological agents, are the main cost driver in complex perianal CD; costs due to surgery and hospitalizations are much lower.

Trees are modular organisms that adjust their within-crown morphology and physiology in response to within-crown light gradients. However, whether within-plant variation represents a strategy for optimizing light absorption has not been formally tested. We investigated the arrangement of the photosynthetic surface throughout one day and its effects on the photosynthetic process, at the most exposed and most sheltered crown layers of a wild olive tree (Olea europaea L.). Similar measurements were made for cuttings taken from this individual and grown in a greenhouse at contrasted irradiance-levels (100 and 20% full sunlight). Diurnal variations in light interception, carbon fixation and carbohydrate accumulation in sun leaves were negatively correlated with those in shade leaves under field conditions when light intensity was not limiting. Despite genetic identity, these complementary patterns were not found in plants grown in the greenhouse. The temporal disparity among crown positions derived from specialization of the photosynthetic behaviour at different functional and spatial scales: architectural structure (crown level) and carbon budget (leaf level). Our results suggest that the profitability of producing a new module may not only respond to construction costs or light availability, but also rely on its spatio-temporal integration within the productive processes at the whole-crown level.

Geographical isolation and polyploidization are central concepts in plant evolution. The hierarchical organization of archipelagos in this study provides a framework for testing the evolutionary consequences for polyploid taxa and populations occurring in isolation. Using amplified fragment length polymorphism and simple sequence repeat markers, we determined the genetic diversity and differentiation patterns at three levels of geographical isolation in Olea europaea: mainland-archipelagos, islands within an archipelago, and populations within an island. At the subspecies scale, the hexaploid ssp. maroccana (southwest Morocco) exhibited higher genetic diversity than the insular counterparts. In contrast, the tetraploid ssp. cerasiformis (Madeira) displayed values similar to those obtained for the diploid ssp. guanchica (Canary Islands). Geographical isolation was associated with a high genetic differentiation at this scale. In the Canarian archipelago, the stepping-stone model of differentiation suggested in a previous study was partially supported. Within the western lineage, an east-to-west differentiation pattern was confirmed. Conversely, the easternmost populations were more related to the mainland ssp. europaea than to the western guanchica lineage. Genetic diversity across the Canarian archipelago was significantly correlated with the date of the last volcanic activity in the area/island where each population occurs. At the island scale, this pattern was not confirmed in older islands (Tenerife and Madeira), where populations were genetically homogeneous. In contrast, founder effects resulted in low genetic diversity and marked genetic differentiation among populations of the youngest island, La Palma.

Celiac disease can present great clinical heterogeneity. Its association with a series of intestinal and non-intestinal diseases, whether immunologically mediated or otherwise, presents a higher than normal frequency. We present a patient with celiac disease and Budd-Chiari syndrome of unknown cause. This association has previously been described only in isolated cases in northern Africa. The appearance of this case in Spain reveals that the coexistence of both processes in a single patient is unlikely to be due to environmental or geographical factors.

Data from a representative sample of the Spanish population (1,949 participants between ages 18 and 65) were analyzed to examine the strength of the principal romantic myths and the link between sex, love, and marriage in Spain. A survey was made up and was administered by interviewers. The results show the strength of these myths and the relationship between the three above-mentioned variables. Women, people with fewer years of formal education, and older people were more likely to believe in the myths and the relation between sex, love, and marriage was stronger in these groups. The findings are discussed in terms of different psychosocial theories.

Eosinophilic cholecystitis is a rare form of cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. The etiology remains obscure, although it had been associated with allergies, parasites, hypereosinophilic syndromes, eosinophilic gastroenteritis, cholelithiasis, and acalculous cholecystitis. Here we report an eosinophilic cholecystitis gallstone-associated case, the only one with this histopathologic diagnosis among 5,537 cholecystectomies made in our hospital in the last years.

Percutaneous endoscopic gastrojejunostomy is a percutaneous endoscopic gastrostomy derived technique, that is widely employed. However it has a high incidence of mechanic complications. Percutaneous endoscopic jejunostomy direct access, improves these problems and allows to apply this technique in patients with previous gastric resection or with other gastric diseases that contraindicate percutaneous endoscopic gastrostomy. We describe, for the first time in our country, a direct percutaneous endoscopic jejunostomy placement.
