RESUMEN
Abstract Introduction Deep interarytenoid groove (DIG) may cause swallowing dysfunction in children; however, the management of DIG has not been established. Objective We evaluated the subjective and objective outcomes of interarytenoid augmentation with injection in children with DIG. Methods Consecutive children under 18 years of age who underwent injection laryngoplasty for DIG were reviewed. Data pertaining to demographics, past medical history, past surgical history, and results of pre and postoperative video fluoroscopic swallow study (VFSS) were obtained. The primary outcome measure was the presence of thin liquid aspiration or penetration on postoperative VFSS. The secondary outcome measure was caregiver-reported improvement of symptoms. Results Twenty-seven patients had VFSS before and after interarytenoid augmentation with injection (IA). Twenty (70%) had thin liquid penetration and 12 (44%) had thin liquid aspiration before the IA. Thin liquid aspiration resolved in 9 children (45%) and persisted in 11 (55%). Of the 12 children who had thin liquid aspiration prior to IA, 6 (50%) had resolution of thin liquid aspiration after IA. Conclusions Injection laryngoplasty is a safe tool to improve swallowing function in children with DIG. Further studies are needed to assess the long-term outcomes of IA and identify predictors of successful IA in children with DIG.
RESUMEN
The aim of this study was to identify the single-nucleotide polymorphisms (SNPs) in bovine candidate genes CLEC7A, CD209 and TLR4, and explore the association between these SNPs with the occurrence of bovine paratuberculosis (PTB) disease. For this purpose, 549 animals were screened by a panel of four diagnostic tests, namely Johnin PPD test, ELISA test, faecal microscopy and IS900 blood PCR against Mycobacterium avium ssp. paratuberculosis (MAP) to develop case–control populations. SNPs were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. Genotypic–phenotypic associations were assessed by the PROCLOGISTIC procedure of SAS 9.3. Of the seven SNPs; rs110353594 in CLEC7A gene and rs8193046 in TLR4 gene were found to be associated with PTB. For SNP rs110353594, odds of CC and CT genotypes vs TT genotype was 1.543 (0.420–5.667; 95% CI) and 0.284 (0.104–0.774; 95% CI), respectively which means that CT genotype was more resistant than TT and CC genotypes against bovine PTB. For SNP rs8193046, odds of AA and AG genotypes versus GG genotype was 0.947 (0.296–3.034; 95% CI) and 3.947 (1.555–10.022; 95% CI), respectively, i.e. probability for getting an infection in animals with AG genotype was 3.94 times more as compared to GG genotype. Hence, a selection programme favouring CT genotype for rs110353594 and against AG genotype for rs8193046 may be beneficial for conferring resistance against bovine PTB
