Search for Dark Matter Axions with CAST-CAPP.

The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has searched for axions in the 19.74 µeV to 22.47 µeV mass range. The detection concept follows the Sikivie haloscope principle, where Dark Matter axions convert into photons within a resonator immersed in a magnetic field. The CAST-CAPP resonator is an array of four individual rectangular cavities inserted in a strong dipole magnet, phase-matched to maximize the detection sensitivity. Here we report on the data acquired for 4124 h from 2019 to 2021. Each cavity is equipped with a fast frequency tuning mechanism of 10 MHz/ min between 4.774 GHz and 5.434 GHz. In the present work, we exclude axion-photon couplings for virialized galactic axions down to gaγγ = 8 × 10-14 GeV-1 at the 90% confidence level. The here implemented phase-matching technique also allows for future large-scale upgrades.

[Peritonsillar abscess: treatment guidelines]. / Absceso periamigdalino: protocolo de tratamiento.

A prospective study was carried out on 25 patients showing symptoms suggestive of peritonsillar abscess. Twelve patients were treated with i.v. antibiotics and three months later underwent tonsillectomy. Thirteen patients underwent acute tonsillectomy within 24-48 hours. In order to evaluate the benefits of acute tonsillectomy we compared three parameters; operation length, intraoperative bleeding and overall length of hospitalization.

[Inverted papillomas of the nasal sinuses]. / Papilomas invertidos nasosinusales.

After reviewing the Arnau de Vilanova Hospital's records, a total of ten cases of inverted papillomas were found. Nasal obstruction was present in 100% of the cases. External surgery was performed in 70% of these patients, finding that in 50% of them, the real size of the tumor was smaller than that show in the radiological study. After surgical treatment, only one of the patients developed a malignant tumor. Incidence of papilloma recurrence was 30%.

[Lymphoepithelioma of the larynx]. / Linfoepitelioma laríngeo.

Non-nasopharyngeal Lymphoepithelioma is a tumor of undifferentiated non-keratinizing cells enclosed in an lymphocytic stroma. The lymphoid tissue does not participate in the tumor process. Its tendency is to precociously spreading in the lymph nodes and viscera, but shows a good radiotherapeutic response. Unlike the nasopharyngeal lymphoepithelioma there is no etiological relationship with the Epstein-Barr virus, in spite of the histological similitudes, therefore the pathogenesis must be different in each. Discrimination between lymphoepithelioma and other neoplasms of the epithelial lineage is important in order to indicate the treatment and also to provide prognostic information.

[Cervical cystic hygroma]. / Higroma quistico cervical.

Hygroma being a rare overgrowth the AA. of the paper consider interesting the report of a case sitting in the neck, diagnosed and treated at Arnau de Vilanova Hospital. Memento concerning this entity.

[Review of ORL manifestations in AIDS. Case series at the Arnau de Vilanova Hospital, Lleida]. / Revisión de las manifestaciones O.R.L. en el SIDA. Casuística del Hospital Arnau de Vilanova, de Lleida.

The majority of patients suffering AIDS-syndrome present with ENT aspects, being the most prevalent lateral adenopathy of the neck firstly, followed by thrush, pharyngo-esophageal candidiasis and herpes simplex. Differences regarding the distribution in percentage in risk groups are signaled by the AA. between their own statistics and those of the americans writers.

[Recurrent polychondritis]. / Policondritis recidivante.

The interest of the relapsing polychondritis is specially due to its otolaryngological implications. The case reported evolved favourably and responded fairish to the corticoidtherapy. Nevertheless an assidous follow-up will be wise in order to stablish the pronostic in view of the outbreacks of the illness. The AA. compare the own case with others referred to in the literature.
