Arthroscopic stabilisation of an acute acromioclavicular dislocation grade III in a patient with ectopic insertion of the pectoralis minor: technical considerations

The different approaches used in arthroscopic stabilisation of the acromioclavicular joint are well known. However, and despite a great incidence of ectopic pectoralis minor insertion, an alternative choice for the use of arthroscopic portal has not being sufficiently described. Here, we describe a case of acute acromioclavicular dislocation grade III. The arthroscopic stabilisation was achieved using the TightRope (Arthrex, Naples, USA) implant. Through this technique, the approach to the articular portion of the coracoid process can be made intra-articularly or from the subacromial space. We accessed intra-articularly, by opening the rotator interval to reach the coracoid process from the joint cavity. After opening the rotator interval, an ectopic insertion of the pectoralis minor was observed. The choice of approach of the coracoid process from the subacromial space would have complicated the intervention, making it necessary to sever the ectopic tendon to complete the technique, lengthening the surgical time and increasing the chance of complications. For this reason, the use of a standard posterior portal providing intra-articular arthroscopic access through the rotator interval is recommended since the aforementioned anatomical variation is not infrequent.

An extended Herschel drop-out source in the center of AS1063: a normal dusty galaxy at z=6.1 or SZ substructures?

In the course of our 870 μm APEX/LABOCA follow-up of the Herschel Lensing Survey we have detected a source in AS1063 (RXC J2248.7-4431) that has no counterparts in any of the Herschel PACS/SPIRE bands, it is a Herschel “drop-out” with S_870/S_500 ≥ 0.5. The 870 μm emission is extended and centered on the brightest cluster galaxy, suggesting either a multiply imaged background source or substructure in the Sunyaev-Zel’dovich increment due to inhomogeneities in the hot cluster gas of this merging cluster. We discuss both interpretations with emphasis on the putative lensed source. Based on the observed properties and on our lens model we find that this source may be the first submillimeter galaxy (SMG) with a moderate far-infrared (FIR) luminosity (L_FIR < 10^12 L_⊙) detected so far at z > 4. In deep HST observations we identified a multiply imaged z ~ 6 source and measured its spectroscopic redshift to be z = 6.107 with VLT/FORS. This source may be associated with the putative SMG, but it is most likely offset spatially by 10−30 kpc and they may be interacting galaxies. With a FIR luminosity in the range [5−15] × 10^11 L_⊙ corresponding to a star formation rate in the range [80−260] M_⊙ yr^-1, this SMG would be more representative of the z > 4 dusty galaxies than the extreme starbursts detected so far. With a total magnification of ~25 it would open a unique window to the normal dusty galaxies at the end of the epoch of reionization.

Avel·lí Artís i Balaguer (1881-1954), comediógrafo e impresor-editor. Entre la plenitud del cambio de siglos y el exilio

This thesis has its origin in a previous work: “The Catalan theatrical life in the magazine ‘El Teatre Català’ (1912-1917)” (DEA, UCM, 2004-2005), focused on the history, description and the indexes of that magazine. Among the historical and literary references ordered there, we chose a figure that would make a monographic work resulting in the present Doctoral Thesis. The choice fell on Avel·lí Artís i Balaguer (1881-1954), whose personality and literary corpus, allow additional possibilities for research. The cultural and literary reach of his life and his work covers a whole historical cycle in Catalan culture and literature, which moves from its contemporary consolidation towards the drama of its temporal dislocation, between the Spanish Civil War and the exile experience. This e historical itinerary is represented by Avel·lí Artís i Balaguer, being a playwright and a publisher. He’s been considered a comedy playwright since his editions bear titles such as “comedy”, “pas comedy”, “sainet” “quadro”, “farce” or “dialogue”, at most we find the word “Drama” once and “tragicomedy” twice, and we can find all this, in a series of texts for the representation ranging from 1909 to 1938. Secondly, as a professional fully involved in printing and publishing, thereby covering since its first steps as a compositor in the late nineties of the 19th century until his activity as a crucial character for magazines and other publishing projects, from the first decade of the 20th century until the last year of his Mexican exile...
