A novel management of streptococcal pharyngotonsillar infections by laser-activated silver nanoparticles and methylene blue conjugate, in vitro study

Species of Streptococcus are classified based on their hemolytic properties ‏ into alpha and beta types. And, since antimicrobial drug resistance is an increasingly problematic issue, the efforts to develop modalities that would overcome this obstacle and avoid antibiotic side effects is an ongoing challenge.

Exome sequencing identifies a novel missense mutation of WFS1 as the cause of non-syndromic low-frequency hearing loss in a Chinese family

Autosomal dominant non-syndromic low-frequency sensorineural hearing loss (LFSNHL) DFNA6/14/38 is an uncommon type of hearing loss that classically affects low frequencies of 2000 Hz and below, demonstrating an ascending configuration. The current study aimed to investigate the cause of LFSNHL in a five-generation Chinese family.

Functional endoscopic sinus surgery improves the quality of life in children suffering from chronic rhinosinusitis with nasal polyps

To evaluate the impact of FESS in children with chronic rhinosinusitis with nasal polyps, regarding their overall postoperative quality-of-life (QoL) and constituent QoL domains. Potential differences between cystic fibrosis (CF) sufferers and non-sufferers, or cases with recurrent sinonasal polyposis versus single-operations were also explored.

Absence of KCNQ4 mutation in Bengali families with ADNSHL originated from West Bengal, India

Autosomal Dominant Non-Syndromic Hearing Loss (ADNSHL) is extremely heterogeneous in nature. More than 60 loci with 30 different genes have been identified linked to ADNSHL. Mutation in KCNQ4 is considered as one of the most common causative factor responsible for ADNSHL. No study focused on the genetic alteration of KCNQ4 gene among hearing loss patients in India. The present study for the first time was carried out to determine the mutation spectrum of KCNQ4 gene in ADNSHL patients of West Bengal state, India.

Bilateral congenital cholesteatoma: Surgical treatment and considerations

To describe a multicenter study regarding surgical management of bilateral congenital cholesteatoma (BCC) and underline the importance of endoscopes in the management of this condition. In BCC, hearing preservation is more crucial than in unilateral cases. The endoscopic approach allows complete removal of cholesteatoma via a minimally invasive technique offering low residual disease rates while preserving the normal physiology of the middle ear and possibly the ossicular chain.

Update on the supraclavicular flap.

Purpose of review: The purpose of this study is to describe the supraclavicular flap and its utility in head and neck reconstruction in the context of recent studies. Recent findings: Current literature regarding the supraclavicular flap has described its expanded uses in a variety of head and neck reconstructive settings. Its reliability and limited morbidity have been well demonstrated, and it has been cited as a reasonable alternative to other reconstructive options including, in some situations, free tissue transfer. Summary: The supraclavicular flap has shown dependability in reconstruction of defects in the head and neck, and it warrants consideration among reconstructive surgeons, especially for circumstances in which free tissue or other pedicled flaps are less than ideal.

Clinical performance validation of PITX2 DNA methylation as prognostic biomarker in patients with head and neck squamous cell carcinoma

by Verena Sailer, Heidrun Gevensleben, Joern Dietrich, Diane Goltz, Glen Kristiansen, Friedrich Bootz, Dimo Dietrich

Background

Despite advances in combined modality therapy, outcomes in head and neck squamous cell cancer (HNSCC) remain dismal with five-year overall survival rates of less than 50%. Prognostic biomarkers are urgently needed to identify patients with a high risk of death after initial curative treatment. Methylation status of the paired-like homeodomain transcription factor 2 (PITX2) has recently emerged as a powerful prognostic biomarker in various cancers. In the present study, the clinical performance of PITX2 methylation was validated in a HNSCC cohort by means of an independent analytical platform (Infinium HumanMethylation450 BeadChip, Illumina, Inc.).

Methods

A total of 528 HNSCC patients from The Cancer Genome Atlas (TCGA) were included in the study. Death was defined as primary endpoint. PITX2 methylation was correlated with overall survival and clinicopathological parameters.

Results

PITX2 methylation was significantly associated with sex, tumor site, p16 status, and grade. In univariate Cox proportional hazards analysis, PITX2 hypermethylation analyzed as continuous and dichotomized variable was significantly associated with prolonged overall survival of HNSCC patients (continuous: hazard ratio (HR) = 0.19 [95%CI: 0.04–0.88], p = 0.034; dichotomized: HR = 0.52 [95%CI: 0.33–0.84], p = 0.007). In multivariate Cox analysis including established clinicopathological parameters, PITX2 promoter methylation was confirmed as prognostic factor (HR = 0.28 [95%CI: 0.09–0.84], p = 0.023).

Conclusion

Using an independent analytical platform, PITX2 methylation was validated as a prognostic biomarker in HNSCC patients, identifying patients that potentially benefit from intensified surveillance and/or administration of adjuvant/neodjuvant treatment, i.e. immunotherapy.
