Nail and hair findings developing in patients treated for COVID-19 infection fluorescence of keratinized tissues on Wood's lamp in COVID-19 disease.

BACKGROUND: The new severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) is the causative agent of coronavirus 2019 (COVID-2019) disease. A wide variety of symptoms of the disease has been frequently reported in the literature in recent years. However, information on the findings in keratinized tissues is still limited. Data on changes in keratinized tissues such as nails, teeth and hair, and oral mucousa due to drugs used in the treatment of this disease are also extremely insufficient. AIM: With this study, it was aimed to evaluate the changes in the keratinized tissues of our patients with COVID-19, who are frequently encountered in the Ear Nose and Throat outpatient clinic. MATERIALS AND METHOD: The study was carried out on patients who applied to Baskent University Ear Nose and Throat clinic. There were 3 groups. The first group consisted of patients diagnosed with COVID-19 and received relevant medical treatments, the second group included individuals who have never experienced COVID-19 infection but have been vaccinated against COVID-19, and the third group is the control group with normal healthy individuals who have never been diagnosed with COVID-19 infection and have not been vaccinated so far. With the Wood's lamp, fluorescent changes in nails, hair, tooth, and the oral mucousa were recorded. RESULTS: A total of 124(75 females, 49 males) patients were included in the study. Positive Wood's finding was significantly higher in COVID-19 group(Group 1) who received Favipravir when compared with individuals who did not receive Favipravir (p < 0.001). Wood's positivity was not detected in any of the individuals who did not use favipravir. The rate of determining Wood's positivity in favipravir users decreases after 58 days. DISCUSSION: Accordingly, Favipravir accumulation in the kretainized tissues manifest positive Wood's sign in our study. CONCLUSION: The adverse effects of the accumulation of the drugs-mainly Favipravir-used in the treatment of COVID-19 disease, have not yet been clearly demonstrated so far. Revealing the findings in these tissues with this study will pave the way for investigating changes or drug sequestrations in other organs in the long term.

Evaluation of the hearing status in carpenters.

PURPOSE: Carpenters are constantly exposed to a noise level of 82-100 dB(A) in their professional lives. The aim of this study is to evaluate the hearing status of carpenters with pure -tone audiometry and transient evoked otoacoustic emissions test. METHODS: A total of 62 individuals were enrolled. The study group consisted of 31 carpenters and the controls were age and sex matched healthy individuals who were not exposed to continuous or sudden noise. RESULTS: The average age of the carpenters is 44.58 ± 10.33, the average age of the control group is 41.84 ± 8.65 and there was no statistically significant difference (p = 0.262). There was a significant hearing loss in the study group nearly at all frequencies when compared to the control group (p < 0.05). The emission values of the right and left ears of the carpenters were significantly lower than the controls at 2000 and 2800 Hz (p < 0.05). CONCLUSION: Accordingly, carpenters seem to be susceptible to the development of noise-induced hearing loss.

Audiovestibular Dysfunction in Patients with Fibromyalgia Syndrome.

OBJECTIVES: Fibromyalgia syndrome is a disorder of widespread pain with unknown etiology. These patients frequently suffer from otologic complaints. This study aims to analyze the audiovestibular functions in patients with fibromyalgia syndrome. METHODS: The study included 33 fibromyalgia patients and 33 healthy volunteers. All the study subjects underwent audiological assessment, multifrequency tympanometry, transient otoacoustic emission, and ocular and cervical vestibular-evoked myogenic potentials tests. RESULTS: Pure-tone hearing thresholds of right and left ears were found to be decreased in fibromyalgia patients compared to controls (P < 0.05). Middle ear resonance frequency values were significantly decreased in patients with fibromyalgia syndrome compared to controls (P < .05). The values for signal-to-noise ratios were higher in controls than in the FMS patients. The difference was significant for 1000, 2000, and 4000 Hz (P > .005). Cervical vestibular-evoked myogenic potential waves were obtained in all controls, but could not be obtained in 5 right ears and 4 left ears of the fibromyalgia patients (P < .05). Also, ocular vestibular-evoked myogenic potentials were obtained in all controls, but could not be obtained in 7 right ears and 10 left ears of the patients with fibromyalgia syndrome (P < .05). CONCLUSION: Our findings support the presence of audiovestibular dysfunction in patients with fibromyalgia. Further research that focuses on the pathogenesis of these dysfunctions is required.

The Impact of Serum 25-Hydroxyvitamin D3 Levels on Allergic Rhinitis.

We aimed to clarify the relation between allergic rhinitis and the serum levels of 25-hydroxivitamin D in the adult population. The study group consisted of 86 patients with allergic rhinitis who were diagnosed with the help of history of allergy, positive signs for allergy, blood samples, and positive skin prick tests; while the control group included 43 age- and sex-matched healthy volunteers with negative skin prick tests. The demographic data, medical history, findings in the physical examinations, serum levels of total immunoglobulin E (IgE) and 25-hydroxyvitamin D, and skin prick test results of the groups were noted. A total of 129 patients fulfilling the necessary criteria were enrolled. The median serum 25-hydroxyvitamin D levels in the study group were significantly lower compared to the control group (P = .014). In the study group, median serum vitamin D levels were significantly higher in men, compared to women (P = .03). There was a significant negative correlation between IgE and vitamin D levels in the allergic rhinitis group (P = .028, r = -0.246). This study showed that patients with allergic rhinitis might be more vulnerable to have lower serum levels of vitamin D. Thus, vitamin D supplementation as an adjunctive therapy may be considered in those patients.

Proliferating Trichilemmal Tumor of the Auricula: A Very Rare Locus.

Proliferating trichilemmal tumor (PTT) is a rare but morphologically characteristic tumor, derived from the external root sheath. They are commonly localized as a solitary lesion on the scalp. They rarely occur in other regions. PTTs generally behave in a benign fashion, up to 20% of the lesions may undergo malignant transformation into squamous carcinoma. We present an elderly woman with a cystic swelling on the crus of auricular helix diagnosed as PTT. To our knowledge, this is the first case in the English literature, of PTT of the auricula.

Audio-Vestibular Findings in Increased Intracranial Hypertension Syndrome.

OBJECTIVE: Idiopathic intracranial hypertension (IIH) can be manifested by audiological and vestibular complaints. The aim of the present study is to determine the audio-vestibular pathologies and their pathophysiologies in this syndrome by performing current audio-vestibular tests. MATERIALS AND METHODS: The study was performed prospectively on 40 individuals (20 IIH patients, 20 healthy volunteers). Pure tone audiometry, tympanometry, vestibular evoked myogenic potentials, and electronystagmography tests were performed in both groups and the results were compared. RESULTS: The mean age of both groups was found to be 30.2±18.7. There were 11 females and 9 males in each group. The study group patients had significantly worse hearing levels. Pure tone averages were significantly higher in both ears of the study group (p<0.05). Ten patients (50%) in the study group and one healthy volunteer (5%) had pathologic ENG, possibly related to central pathologies (p=0.008). Eight patients (40%) and one (5%) control had variable abnormal VEMP records (p=0008). CONCLUSION: Many IIH patients initially visit otolaryngology clinics since cochlear and vestibular systems are frequently affected in this condition. Our test results suggest inner ear pathologies in these patients. Higher incidence of inferior vestibular nerve and/or saccule dysfunction is detected as a novelty. Increased intracranial pressure may affect the inner ear with similar mechanisms as in hydrops.

Benign Paroxysmal Positional Vertigo in Pregnancy.

Benign paroxysmal positional vertigo (BPPV) is a clinical entity characterized by acute, brief paroxysmal attacks of rotational vertigo induced by head position changes. It is the most common peripheral vestibular pathology and is seen more frequently in women. However, to our knowledge, there is very limited data on the association between BPPV and pregnancy in both English and Turkish literature. We present four pregnant women diagnosed with BPPV for the first time during gestation and revise the etiological factors of BPPV and the role of pregnancy-related changes in BPPV.
