An increasing number of randomized controlled trials and two meta-analyses have confirmed that it is an effective and safe procedure (1). A recent meta-analysis has reported the possibility of higher rate of symptoms recurrence (2-3). The higher recurrence rate may be related to the size of the haemorrhoids as well as the achieved size of the resected haemorrhoidal tissue “donought”. It is currently recommended that diathermy haemorrhoidectomy may be a better treatment for fourth degree haemorrhoids with a significant external component.

Αρκετοί από τους επαγγελματίες παραπονούνται ότι δυσκολεύονται στην εργασία τους εξαιτίας της ακοής τους, παρόλο που αυτό δεν διαπιστώνεται με την κλασική ακοομετρία. Δεν υπάρχει μέχρι στιγμής σαφής τρόπος διάγνωσης της λειτουργικής επίπτωσης των διαταραχών ακοής σε επαγγελματίες μουσικούς. Από το παραπάνω προκύπτει η ανάγκη για τη δημιουργία αλληλουχίας και αξιολόγησης ακοολογικών δοκιμασιών, καθώς και η ποσοτικοποίηση της δυσκολίας που αντιμετωπίζουν στην απόδοση στην εργασία τους και την καθημερινότητά τους.

Although pure-tone audiometry is often considered the “gold standard” and is usually employed as the main instrument for hearing assessment, it cannot fully describe the impact of hearing dysfunction. The MHHI is an attempt to complement the hearing impairment assessment toolbox and is based on a unique approach to quantify the effects of hearing-related symptoms or hearing loss on the performance of musicians and other music industry professionals. Method An initial set of 143 questionnaire items was successively refined through a series of critical appraisals, modifications, and suggestions. This yielded an intermediate questionnaire consisting of 43 items, which was administered to 204 musicians and sound engineers. After exploratory factor analysis, the final form of the MHHI questio...

The impact of self-produced sound exposure on singers' hearing within the rehearsal setting has not been examined. OBJECTIVES This original pilot field study investigates the feasibility of data collection and hypothesis testing of singers' hearing within the rehearsal environment. METHODS 18 professional choir singers are examined for hearing threshold changes following routine rehearsal sound exposure. Pure Tone Audiometry is measured before, immediately after, and approximately 24 hours after rehearsal. RESULTS This study does not identify definitive Temporary Threshold Shift in this population under these conditions. That said, mean temporary threshold shift was found 3.61 dB higher than the recovery threshold shift in the right ear at 3000 Hz (P = 0.06), and this may be important to look...

Its clinical significance and correlation with the pathophysiology and treatment prognosis of tinnitus remain enigmatic. The objective of this review is to critically appraise scientific evidence regarding the residual inhibition prevalence and how it is correlated with different sound stimuli. METHODS A systematic review of tinnitus Residual Inhibition (RI) studies was performed, focusing on prevalence, methods used, stimuli presented and responses obtained. A literature search (PubMed, Cochrane Central Register of Controlled Trials, Scopus, MEDLINE) was conducted. Seventeen studies involving 1066 patients fulfilled the inclusion criteria. Sound stimulation was performed using pure tones, customized sounds, narrow- and broadband noises, and modulated sounds. RESULTS Sound stimuli exposure produced complete RI of tinnitus in 34.5% of patients (range 5.6-72%), with higher RI rates...

Findings from human studies, mainly targeting on effect of chronic exposure are controversial. Aim of this study is to investigate the immediate effect of noise exposure to synaptic function with use of ABR and DPOAEs.Methods: Ten participants with normal hearing levels underwent DP-gram between 1 and 6 KHz and ABR at 90dB and click rates 33/sec and 44/sec before and after exposure to standardized music. Four of them were professional musicians and six were controls. Material for reliable and constant exposure to music was created, consisting of 56 wav files with music with a total duration of 2.5 hours. Files were presented in stable dB SPL levels and absolute control of dB SPL levels to ear phones was ensured. Subjects were asked to listen to music of their preference in maximum for 30 minutes. Patients e...
