Cross-Cultural Adaptation and Validation of the Voice Handicap Index Into Greek

The objective was to culturally adapt and validate the Voice Handicap Index (VHI) to the Greek language. The study design used was a psychometric analysis. The VHI was translated into Greek with cultural adaptations to accommodate certain words. The translated version was then completed by 67 subjects with various voice disorders and by a control group of 79 subjects. All the participants also completed a self-rating scale regarding the severity of their voice disorder. Statistical analyses demonstrated high internal consistency and high test-retest reliability both for the overall VHI score and for the functional, physical, and emotional domains of the VHI. A moderate correlation was found between the VHI and the self-rating severity scale. The subjects in the control group had lower scores compared to the subjects with voice disorders for the overall VHI score and for the three domains. Based on the internal consistency values and the test-retest reliability, the Greek version of VHI is a valid and reliable measure for use by Greek subjects with voice disorders.

Extrinsic ageing in the human skin is associated with alterations in the expression of hyaluronic acid and its metabolizing enzymes

Abstract:  Extrinsic skin ageing or ‘photoageing’, as opposed to intrinsic skin ageing, is the result of exposure to external factors, mainly ultraviolet irradiation. Glycosaminoglycans (GAG) and particularly hyaluronic acid (HA) are major components of the cutaneous extracellular matrix involved in tissue repair. However, their involvement in extrinsic skin ageing remains elusive. In this study, we investigated the expression of HA and its metabolizing enzymes in photoexposed and photoprotected human skin tissue specimens, obtained from the same patient. Total GAG were isolated, characterized using specific GAG‐degrading enzymes and separated by electrophoresis on cellulose acetate membranes and polyacrylamide gels. Quantitation of HA in total GAG was performed using ELISA. Gene expression of hyaluronan synthases (HAS), hyaluronidases (HYAL) and HA receptors CD44 and receptor for HA‐mediated motility (RHAMM) was assessed by RT‐PCR. We detected a significant increase in the expression of HA, of lower molecular mass, in photoexposed skin as compared with photoprotected skin. This increase was associated with a significant decrease in the expression of HAS1 and an increase in the expression of HYAL1‐3. Furthermore, the expression of HA receptors CD44 and RHAMM was significantly downregulated in photoexposed as compared with photoprotected skin. These findings indicate that extrinsic skin ageing is characterized by distinct homoeostasis of HA. The elucidation of the role of HA homoeostasis in extrinsic skin ageing may offer an additional approach in handling cutaneous ageing.

Tuberculous otitis media: a difficult diagnosis and report of four cases.

Tuberculous otitis media is a rare disease. Due to the conditions rarity and its usually indolent course, the diagnosis is often delayed. This can lead to irreversible complications, such as permanent hearing loss or facial nerve paralysis. Tuberculosis of the middle ear cleft, as this diseases first presentation, is indeed very rare. Surgery may be carried out prior to diagnosis occasionally, i.e., middle ear exploration for chronic middle ear disease. We present four cases of tuberculous otitis media which occurred as the first presentation of the disease. The patients did not present with the classic symptoms of middle ear tuberculosis. The diagnosis was based on the histology following middle ear exploration for chronic middle ear disease. None of the patients presented any other systemic involvement. We present a review of this diseases clinical symptoms and the diagnostic tests available.

Olfactory dysfunction in nasal polyposis: correlation with computed tomography findings.

Aims: This study evaluates if a computed tomography (CT) scan is useful to assess the olfactory loss in sinonasal disease, and if a preoperative CT scan has a predictive value for the long-term outcome regarding olfaction. Methods: Thirty-one patients with nasal polyposis were included. Olfactory function was assessed with the ‘Sniffin’ Sticks’ test and subjective perception recorded with a visual analogue scale. CT scans were assessed with the Lund-Mackay system and the Damm nasal segmentation. Patients were retested after endoscopic sinus surgery in a follow-up appointment at least 1 year later. Results: Disease in the upper meatus and the posterior portion of the middle meatus strongly affects olfactory function. Lund-Mackay scores were significantly correlated with preoperative olfactory test results. Preoperative subjective ratings had a significant correlation only with present disease in the anterior upper meatus. Postoperative results were significantly decreased. Their relative percentage change was correlated only with the preoperative presence of disease in the anterior upper meatus. No correlation was found between the Lund-Mackay score and the postoperative olfactory results. Conclusions: Olfactory dysfunction in nasal polyposis is strongly related to specific obstructed nasal areas. A CT scan has no predictive value for the long-term surgical outcome regarding olfaction.

Assessing Laryngopharyngeal Reflux Symptoms with the Reflux Symptom Index Validation and Prevalence in the Greek Population

Objective. To validate the Reflux Symptom Index (RSI) in Greek patients and estimate the prevalence of laryngopharyngeal reflux (LPR) symptoms in the Greek population. Study Design. Prospective, controlled validation study. Setting. Tertiary referral hospital and primary care. Subjects and Methods. For validation purposes, the instrument was administered to 53 patients with confirmed LPR. Sex- and age-matched controls with no LPR or gastroesophageal reflux disease (GERD) symptoms presenting in a primary care setting composed the control group. Reliability and construct validity were statistically appraised. Using the RSI, the authors estimated the prevalence of LPR in a randomly selected sample of the Greek adult population. Results. The mean (SD) RSI score of the 172 sex- and age-matched controls was 3.2 (3.5). The mean (SD) RSI score of the 53 confirmed LPR patients was 19.9 (6.8). Cronbach α was 0.865. Factor analysis verified that the RSI instrument consists of 2 principal factors. To estimate the prevalence of LPR, a representative sample of the Greek adult population (188 subjects) completed the RSI questionnaire: 36.3% were male, and 29.6% were smokers. Mean (SD) age was 53.4 (17.7) years. The instrument was able to discriminate 16 patients with LPR symptoms with a mean (SD) score of 18.91 (6.39). Conclusion. The authors evaluated the internal consistency, reliability, and construct validity of the RSI for the Greek population. Factor analysis of the Greek translation of the RSI demonstrated that it can be a reliable tool in the diagnostic approach of LPR patients. Using the RSI, the authors recorded that the prevalence of LPR in a representative sample of the Greek population is 8.5%.

This study aims to compare the taste function between smokers and nonsmokers with clinical testing, subjective ratings, and contact endoscopy of the tongue.

Cartilage-sparing otoplasty: Our experience

Prominent ears are the most frequent congenital deformity in the head and neck area. Otoplasty has undergone important developments and numerous techniques have been employed to address the anatomical defects, namely the lack of antihelix and the overdevelopment of the concha. We present a cartilage-sparing technique involving scapha--conchal sutures insertion to recreate the antihelix, conchal setback and cartilage weakening. No cartilage is excised. Prior to creating the antihelix, the medial surface of the cartilage is superficially scored. Occasionally a tangential excision of the posterior prominence of the cartilage prior to the placement of set back sutures is employed for an excessively large conchal bowl. A series of 86 consecutive patients underwent otoplasty with this technique. According to our experience the described technique gives good and predictable long-term results with a natural-appearing ear. Significant complications are rare. In case of loss of correction, revisional surgery is straightforward on the intact pinna cartilage.

Nodular basal cell carcinoma is associated with increased hyaluronan homeostasis

Background  Basal cell carcinoma (BCC) is one of the most frequent forms of malignancy in humans. Although BCC is a tumour of low degree of malignancy, if left untreated, it can be locally aggressive, eat away at tissues and cause ulceration. Nodular is the most common subtype of BCC (>50%). Although apparently non‐invasive, micronodular, a certain subgroup of nodular, is likely to recur. Glycosaminoglycans (GAGs), such as hyaluronic acid (HA), are extracellular matrix molecules of high importance in malignant transformation, metastasis and other complex remodelling processes.

Nasal mucosal melanoma presenting as central type vertigo: a case report.

Nasal mucosal melanoma presents usually with epistaxis, nasal obstruction and facial pain. However melanoma tends to give distant metastases at an early stage, having rare clinical presentations.We present a 74-year old female patient with symptoms of central type vertigo caused by brain metastases. Clinical assessment for the detection of the primary site revealed a nasal mucosal melanoma originating from the posterior end of the left inferior turbinate. The patient received a combination of radio and chemotherapy being in relatively good condition 8 months later. This is the first reported case of a nasal mucosal melanoma with vertigo as the first presenting symptom.
