Although NLR and PLR are two important markers that can be detected from peripheral blood samples of patients developing idiopathic sudden hearing loss and can be calculated easily, increased NLR values were also found to be related to poor prognosis.

To our best knowledge, our study is the first study in the literature. Although the role of specific mechanisms in SHL is not entirely understood, the capillaroscopic examination can show the importance of microvascular function in SHL. CD and PORH values were found to be low in SHL patients, and a low PORH value was found to be a factor of poor prognosis.

There was no difference in MHRs between study and control groups. However, as MHR was higher in the patients with good prognosis compared with the patients with bad prognosis, we believe that regarding the ISHL, MHR is not a predictive value but might have prognostic marker.

Retropharyngeal abscess (RPA) is the second most common deep neck space infection after peritonsiller abscess in pediatric population. Major signs and symptoms on physical examination include fever, hypersalivation, odynophagia, reduced oral intake, sore throat, swelling on the neck, torticollis, limitation in neck mobility, and voice changes. In this paper, the authors present a case of RPA with unusual and interesting presenting symptoms in a 10-month-old infant that exhibit new-onset and worsening snoring and sleep apnea. The purposes of this manuscript are to present the authors' experience with this patient, to emphasize the diagnosis, clinical course, and management of RPA in infants, also to signify the importance of including RPA in the differential diagnosis of patients with sleep apnea syndrome.
