    PMID: 29527280
    Background: Varicella has been known to be a harmless childhood disease. However, it has been reported that severe complications have taken place following Varicella infection, in both immunocompetent, as well as immunocompromised, individuals. Cutaneous complications of Varicella may manifest as preseptal cellulitis, albeit rarely.

    Report: We present a case of a 4-year-old boy who presented with symptoms and signs of preseptal cellulitis following Varicella infection. He was referred to the otorhinolaryngology team for a nasoendoscopy to rule out sinusitis, in view of the fear that a child presenting with a swollen red eye may be a case of true orbital cellulitis. He was treated successfully with intravenous antibiotics and surgical drainage of the preseptal collection.

    Conclusion: It is imperative for clinicians to be aware that a simple Varicella infection may lead to cutaneous complications in the pediatric age group, especially in children who are 4 years and younger. They may develop preseptal cellulitis, whose presentation might mimic that of orbital cellulitis. Empirical treatment with antibiotics would be advantageous for the patient. A nasoendoscopic examination may also be warranted in these cases to rule out sinusitis as a cause of orbital cellulitis.
  2. Fulltext Sound frequency spectra of snore in relation to the site of obstruction among snorers

    Acta Otorhinolaryngol Ital, 2021 Aug;41(4):348-355.
    PMID: 34533538 DOI: 10.14639/0392-100X-N1202
    Objective: This study aimed to describe the sound frequency of snoring in relation to the site of upper airway vibration among snorers.

    Methods: 383 snores from 40 participants who complained of snoring were digitally recorded during natural and induced sleep using a level III polysomnography monitor with a built-in microphone. During drug-induced sleep endoscopy (DISE), the real-time site of upper airway obstruction was assessed, and the sound frequency of snoring was recorded synchronously.

    Results: The mean peak of snoring frequency for unilevel palatal, oropharynx and epiglottis obstruction were 522.5, 482.4 and 300.0 Hz, respectively. Most participants showed multilevel obstruction at the palate and oropharynx, in which the mean for bi-peak snoring frequency were 402.90 Hz and 1086.96 Hz, respectively. Severity of OSA was significantly associated with multilevel obstruction.

    Conclusions: There was a significant association between the snoring sound frequency and site of unilevel obstruction. Palatal or oropharyngeal obstruction produced sound at mid-frequency range, while the epiglottis produced a low frequency range. Multilevel obstruction documented a bi-peak snoring frequency.
