IntroductionA stronger evidence level is needed to confirm the benefits and limits of laparoscopic hemihepatectomies.MethodsLaparoscopic and open hemihepatectomies from nine European referral centers were compared after propensity score matching (right and left hemihepatectomies separately, and benign and malignant diseases sub‐analyses).ResultsFive hundred and forty‐five laparoscopic hemihepatectomies were compared with 545 open. Laparoscopy was associated with reduced blood loss (P < 0.001), postoperative stay (P < 0.001) and minor morbidity (P = 0.002), supported by a lower Comprehensive Complication Index (CCI) (P = 0.035). Laparoscopic right hemihepatectomies were associated with lower ascites (P = 0.016), bile leak (P = 0.001) and wound infections (P = 0.009). Laparoscopic left hemihepatectomies exhibited a lower incidence of bile leak and cardiovascular complications (P = 0.024; P = 0.041), lower minor and major morbidity (P = 0.003; P = 0.044) and reduced CCI (P = 0.002). Laparoscopic major hepatectomies (LMH) for benign disease were associated with lower blood loss (P = 0.001) and bile leaks (P = 0.037) and shorter total stay (P < 0.001). LMH for malignancy were associated with lower blood loss (P < 0.001) and minor morbidity (P = 0.027) supported by a lower CCI (P = 0.021) and shorter stay (P < 0.001).ConclusionThis multicenter study confirms some associated advantages of laparoscopic left and right hemihepatectomies in malignant and benign conditions highlighting the need for realistic expectations of the minimally invasive approach based on the resected hemiliver and the patients treated.

ObjectiveMany people seek health information from internet sources. Understanding this behaviour can help inform healthcare delivery. This study aimed to review Google Trends as a method for investigating internet-based information-seeking behaviour related to throat cancer in terms of quantity, content and thematic analysis.MethodData was collected using Google Trends. Normalised data was created using the search terms ‘throat cancer’, ‘cancer’, ‘HPV’, ‘laryngeal cancer’ and ‘head and neck cancer’. The search data was used to analyse the temporal and geographical interest pattern of these terms from 2004 to 2015.ResultsThree important peaks in searches for ‘throat cancer’ were identified. The first and greatest increase in interest was in September 2010, and there were also peaks in June 2013 and in October 2011.ConclusionInternet-search analysis can provide an insight into the information-seeking behaviour of the public. Mass media can hugely affect this information-seeking behaviour. Possessing tools to investigate and understand information-seeking behaviour may be used to improve healthcare delivery.

Mastoiditis caused by mycobacterium tuberculosis (TB) has an extremely low incidence in paediatric patients and intracranial complications are even rarer. We report the case of a 2-year-old Caucasian male who presented to a tertiary ENT centre with a left sided mastoid swelling and drowsiness after having been treated unsuccessfully for unresolving ear pain and discharge for 6 weeks. He was subsequently found to have mastoiditis with intracranial complications caused by mycobacterium TB. This report aims to increase awareness of TB as a potential cause of chronic unresolving ear pain in the paediatric age group, as well as the importance of multidisciplinary team management.

Objectives: There are no hearing protection regulations in place for passengers using public transport, such as the London Underground. In light of this, we sought to examine sound pressure levels experienced by regular users of the London Underground. Methods: Sound pressure levels (A-weighted decibels: dBA) were taken on moving London Underground carriages between Euston and South Wimbledon on the Northern Line, and between Euston and Vauxhall on the Victoria Line, during 2006 and 2018. In addition, carriage sound pressure levels travelling within Zone 1 of the London Underground were tested in 2019. Three experimental and three technical repeats were undertaken using a hand-held calibrated multi-function sound level meter. Results: Passengers are routinely and consistently subjected to sound pressure levels exceeding 80 dBA, with levels sometimes reaching over 100 dBA. Conclusion: This study is unique within the literature, with no published studies outlining exposure levels for London Underground passengers. It provides evidence of elevated noise exposure to passengers, consistently along large stretches of the London Underground, over a prolonged study period (2006-2019).
