Fashion retailing – past, present and future

This issue of Textile Progress reviews the way that fashion retailing has developed as a result of the application of the World Wide Web and information and communications technology (ICT) by fashion-retail companies. The review therefore first considers how fashion retailing has evolved, analysing retail formats, global strategies, emerging and developing economies, and the factors that are threatening and driving growth in the fashion-retail market. The second part of the review considers the emergence of omni-channel retailing, analysing how retail has progressed and developed since the adoption of the Internet and how ICT initiatives such as mobile commerce (m-commerce), digital visualisation online, and in-store and self-service technologies have been proven to support the progression and expansion of fashion retailing. The paper concludes with recommendations on future research opportunities for gaining a better understanding of the impacts of ICT and omni-channel retailing, through which it may be possible to increase and develop knowledge and understanding of the way the sector is developing and provide fresh impetus to an already-innovative and competitive industr

Revision surgery for chronically discharging mastoid cavities: mastoid obliteration with canal wall reconstruction versus non-obliteration surgery

Purpose: To evaluate the surgical results of revision canal wall down (CWD) surgery for chronically discharging mastoid cavities and to compare the non-obliteration approach to mastoid obliteration with canal wall reconstruction. Methods: This is a retrospective cohort study. All adult patients (≥ 18 years) who underwent revision surgery for chronically draining mastoid cavities between January 2013 and January 2020 were included. Primary outcome measures included the dry ear rate, complications and postoperative hearing. Results: 79 ears were included; 56 ears received revision CWD with mastoid obliteration and posterior canal wall reconstruction and 23 ears received CWD without mastoid obliteration. The dry ear rate at the most recent outpatient clinic visit (median 28.0 months postoperative) was significantly higher in the obliteration group with 96.4% compared to 73.9% for the non-obliteration group (p =.002). There were no differences in audiological outcome and incidence of complications between the two techniques. Conclusion: We show that in our study population revision CWD surgery with mastoid obliteration and posterior canal wall reconstruction is superior to revision CWD surgery without mastoid obliteration in the management of chronically discharging mastoid cavities. In the obliteration group, a dry ear was achieved in 96.4% as this was 73.9% in the non-obliteration group. We found no differences in audiological outcome and in incidence of complications between the two techniques

Sleep-disordered breathing in middle-aged adults who underwent pharyngeal flap surgery for velopharyngeal insufficiency treatment: polysomnographic analysis

Objetivos: Investigar a ocorrência de apneia obstrutiva do sono (AOS), sua gravidade e sintomas relacionados, em adultos de meia-idade com fissura de palato operada (FPO) e retalho faríngeo, comparativamente a indivíduos com FPO sem retalho e a dados normativos. Adicionalmente, verificar a relação entre a gravidade da AOS e a área seccional mínima da via aérea faríngea (ASF). Método: Estudo prospectivo em 42 indivíduos com FPO, não sindrômicos (22 com retalho- CR, 20 sem retalho-SR), 40-58 anos de idade. A prevalência de AOS foi estimada com base no índice de apneia e hipopneia (IAH) avaliado por polissonografia (sistema EMBLA-N7000). Os sintomas foram investigados pelos questionários de Pittsburgh, Epworth, e Berlin e pela Escala de Trindade. A ASF foi avaliada por rinomanometria anterior modificada em um subgrupo de pacientes dos grupos CR (n=14) e SR (n=10). Local de execução: Unidade de Estudos do Sono-Laboratório de Fisiologia-HRAC/USP. Resultados: No grupo CR, a prevalência de AOS correspondeu a 77%. Quando considerados os sintomas relacionados (SAHOS) foi de 64%. No grupo SR, os percentuais foram menores (60% e 45%, respectivamente), mas as diferenças não foram estatisticamente significantes. A prevalência de SAHOS do grupo CR foi comparativamente maior do que na população em geral. Os indicadores aferidos pelos questionários não diferiram entre os grupos. Não houve correlação entre IAH e ASF. Conclusão: Adultos de meia-idade com fissura palatina apresentam desordens respiratórias do sono em proporção clinicamente significativa, possivelmente relacionadas a alterações anatomo-funcionais das vias aéreas superiores, congênitas ou secundárias às palatoplastias, sendo o retalho um fator obstrutivo agravante.Objectives: To investigate the occurrence and severity of obstructive sleep apnea (OSA) and related symptoms in middle-aged adults with repaired cleft palate and pharyngeal flap, as compared to individuals with repaired cleft palate without flap and to normative data. In addition, to verify the relationship between OSA severity and minimal pharyngeal cross-sectional airway area (PCSA). Methods: Prospective study in 42 nonsyndromic individuals with repaired cleft palate (22 with flap- F group, 20 without flap- NF group), aged 40-58 years. Prevalence of OSA was estimated according to apnea-hipopnea index (AHI), measured by nocturnal polysomnography (EMBLA-N7000 system). Symptoms were investigated by the Pittsburgh, Epworth, and Berlin questionnaires and by the Trindade Scale. PCSA was evaluated by modified anterior rhinomanometry in a subgroup of patients from the F group (n=14) and the NF group (n=10). Setting: Sleep Studies Unit-Laboratory of Physiology, Hospital for Rehabilitation of Craniofacial Anomalies, Brazil. Results: In the F group, the prevalence of OSA corresponded to 77% and when considering related symptoms (OSAHS), 64%. In the NF group, the percentages were lower (60% and 45%, respectively), but differences were not statistically significant. The prevalence of OSAHS in the F group was higher than in the general population. Questionnaire outcomes did not differ between groups. There was no correlation between AHI and PCSA. Conclusion: Middle-aged adults with cleft palate have clinically significant sleep-disordered breathing, possibly related to congenital anatomic or functional abnormalities of the upper airway, or to primary and secondary palatal surgeries, the flap being an aggravating obstructive factor
