Utility of the continuous intraoperative neuromonitoring in the prevention of the recurrent laryngeal nerve paralysis during thyroid surgery. A prospective observational study.

Background: The continuous intraoperative neuromonitoring (C-IONM) of the recurrent laryngeal nerve (RLN) could help reducing the incidence of nerve paralysis after thyroid surgery, in comparison with the mere anatomical visualization of the RLN. The objective is to assess the efficacy and utility of C-IONM as a predictive test for recurrent laryngeal nerve paralysis after thyroidectomy.

Methods: A prospective observational study was performed in 248 patients who underwent thyroid surgery where C-IONM was applied, between September 2018 and December 2019, in a high-volume center.

[LC-MS/MS analysis of herbicide residues in waters from Navarre].

Background: The aim of the study was to obtain information on the residues of herbicides (imazametabenz, simazine, isoproturon, clortoluron, metribuzine, atrazine, cianazine, terbutrin, propanil, terbutilazine, alachlor and pendimetalin) present in water proceeding from Navarre.

Material And Methods: A total of 465 samples of water were taken: 378 were taken from 141 water supplies; the remaining 87 proceeded from fountains, springs and borings in agricultural areas in the south of Navarre. The technique employed was LC-MS/MS.

Cervical carcinoma: human papillomavirus infection and HLA-associated risk factors in the Spanish population.

There is evidence for a link between MHC and squamous cell carcinoma of the cervix (SCCC), and different patterns of association in different patient cohorts have been reported. To investigate this subject in the Spanish population, HLA class I, -II serotypings and HLA-DQB1 oligogenotypings of 142 patients and 138 healthy sex-age-matched controls were performed. Comparative analysis of the DR2-DQ3-stratified phenotypes demonstrated a strong association between DR2 and DQ3 in SCCC (Pc9 < 7 x 10(-8)).

Human leukocyte antigen alleles and haplotypes associated with selective immunoglobulin A deficiency in Spanish pediatric patients.

Class I and II human leukocyte antigens were determined by a standard microlymphocytotoxity test in a group of 45 pediatric patients with selective immunoglobulin A deficiency (IgA-D), 33 of them with frequent respiratory tract infections, allergic diseases, or gastrointestinal disorders (RTIAG), and 12 with celiac disease (CD). The results showed that the DR1 allele, and the A1, B8, Cw7, DR3, DQw2; B35, Cw4, DR1, DQw1; and B14, DR1, DQw1 haplotypes could be involved with IgA-D susceptibility in RTIAG patients. Among the CD-IgA-D group, the B14 allele and A1, B8, Cw7, DR3, DQw2 haplotype were found to confer a high risk of developing IgA-D.
