Fixed drug eruptions (FDE) are adverse cutaneous drug reactions and a form of delayed type 4 hypersensitivity reaction characterised by recurrent lesions at the same site each time a specific drug is taken. They most commonly result in cutaneous lesions presenting as an erythematous round or oval macule or plaque. FDEs have rarely been reported to affect oral mucous membranes and tend to have a bullous or aphthous-like appearance with erythema. Almost half of patients report an increase in the severity of symptoms with prolonged exposure to the offending medication. The most commonly attributed classes of drug are antibiotics (tetracyclines and sulphonamides) alongside non-steroidal anti-inflammatory drugs. Cutaneous adverse reactions to etoricoxib, a highly selective COX-2 inhibitor, have been reported. Here we describe an adverse reaction restricted to the oral mucosa.

Temporomandibular disorders (TMDs) are the second most common form of orofacial pain after an odontogenic source. Despite their complex aetiopathology they are considered a musculoskeletal disorder. They can have a significant impact on the quality of life of those suffering from TMDs, but can be treated and managed through a mixture of conservative and surgical approaches. Physiotherapists specialising in musculoskeletal therapy and pain management can offer a variety of techniques to help in the treatment and management of TMDs. In this narrative review the evolution of physiotherapy practice in the United Kingdom will be outlined, along with a discussion about physiotherapeutic theoretical frameworks in the management of musculoskeletal disorders and idiopathic TMDs. Finally, a narrative review will be presented, outlining the literature exploring the use of physiotherapy post TMJ surgery, underpinned by a systematic literature search on the topic. After screening for inclusion in the narrative review, eight articles were included for narrative synthesis. The main findings were that there is a relative paucity of studies looking at the value of physiotherapy post TMJ surgery compared with the treatment of idiopathic TMDs, and there is heterogeneity in the physiotherapy programmes described in the literature, but the addition of physiotherapy post TMJ surgery seems to augment the patient's response to surgery. The article concludes by describing the domestic challenges and opportunities of integrating physiotherapy into TMD management pathways.

The traditional model of centralisation of care, whilst having many advantages, also requires adaptation and upscaling to meet the requirements of both regional areas and the increasing urban sprawl. However, to ensure comparable outcomes with current major centres, this transition, when required, must be delivered in a safe and effective manner. Our project, which utilised the British Association of Oral and Maxillofacial Surgeons (BAOMS) recently published outcome data from the Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) project to benchmark data prospectively collected from a small-volume, emerging centre in Northern Queensland, was the first of its kind in terms of validation studies. As expected, the small volume of our centre impacted the ability to derive powerful statistical models and comparators, an intrinsic limitation for small-volume centres whilst they are developing services. However, during this evolution project, the use of comparison metrics allowed for the detection of alert and alarm levels, which are invaluable to ensure patient safety and quality of outcome. Our paper demonstrated that, irrespective of size or volume, the utilisation of quality assurance metrics (national or international) provides for the safe and transparent upscaling of head and neck services in emerging, regional, and small-volume centres.

The aim of this study was to determine what is considered a long oral surgery and conduct a cost-effective analysis of sedative agents used for intravenous sedation (IVS) and sedation protocols for such procedures. Pubmed and Google Scholar databases were used to identify human studies employing IVS for extractions and implant-related surgeries, between 2003 and July/2023. Sedation protocols and procedure lengths were documented. Sedative satisfaction, operator satisfaction, and sedation assessment were also recorded. Cost estimation was based on The British National Formulary (BNF). To assess bias, the Cochrane Risk of Bias tools were employed. This review identified 29 randomised control trials (RCT), six cohorts, 14 case-series, and one case-control study. The study defined long procedures with an average duration of 31.33 minutes for extractions and 79.37 minutes for implant-related surgeries. Sedative agents identified were midazolam, dexmedetomidine, propofol, and remimazolam. Cost analysis revealed midazolam as the most cost-effective option (<10 pence per procedure per patient) and propofol the most expensive option (approximately £46.39). Bias analysis indicated varying degrees of bias in the included studies. Due to diverse outcome reporting, a comparative network approach was employed and revealed benefits of using dexmedetomidine, propofol, and remimazolam over midazolam. Midazolam, dexmedetomidine, propofol, and remimazolam demonstrated safety and efficacy as sedative agents for conscious IVS in extended procedures like extractions or implant-related surgeries. While midazolam is the most cost-effective option, dexmedetomidine, propofol, and remimazolam offer subjective and clinical benefits. The relatively higher cost of propofol may impede its widespread use. Dexmedetomidine and remimazolam stand out as closely priced options, necessitating further clinical investigations for comparative efficacy assessment.

The purpose of this paper was to retrospectively assess the local factors that are likely to be associated with the risks for one-year dental implant loss. A retrospective study was designed and implemented. The sample consisted of patients who underwent an implant loss or removal caused by peri-implantitis or infection after prosthesis loading. The chi-squared test and generalised estimating equations (GEE) were used to explore the potential risk factors for one-year implant loss. A total of 279 patients with 287 failed implants were enrolled in this study. Immediate implant placement exhibited a 3.373 (95% CI: 1.652 to 6.886) significantly increased risk to experience one-year implant loss than early and late implant placement (p = 0.001). In addition, implants loaded during a healing period fewer than two months after implant placement were at 18.139 (95% CI: 8.925 to 36.866) significantly higher risk of one-year implant loss when compared with those that loaded within more than two months after implant placement (p < 0.001). Smokers were 1.866 (OR = 1.866,95% CI: 0.993 to 3.510) times as high risk for one-year implant loss as non-smokers, but there were no significant statistical differences (p = 0.053). Immediate implant placement and early implant loading were considered risk factors for one-year implant loss.

The stability provided by load-sharing miniplate osteosynthesis (LSMO) in dentate mandibular fractures (DMF) is usually adequate for bony healing. Non-union following LSMO is an uncommon complication. We aimed to determine the incidence and identify contributing factors, if any, of non-union amongst DMFs that have undergone LSMO. This retrospective case-control study with an allocation ratio of 1:3 includes cases of non-union DMF following LSMO and controls with healed DMF following LSMO over a five-year period. Relevant sociodemographic data, mandibular fracture characteristics, and treatment variables were collected for both groups. Of the 381 patients who underwent LSMO for DMFs, 12 cases of non-union were identified. The control group included 36 patients with uncomplicated healing. A significant association was observed between non-union and teeth in the line of fracture, postoperative infections, and time from injury to LSMO. The odds ratio with chronic alcohol usage was 1.4. Vigilant follow up of patients with chronic alcohol use, those with teeth in the fracture line, and adherence to LSMO principles may help to minimise the non-union complication.

The purpose of this systematic review and meta-analysis was to determine the most effective and least morbid surgical technique for relieving retroglossal airway obstruction in infants with Robin sequence (RS). The study adhered to PRISMA guidelines and included 25 studies (24 cohorts and one case series) that investigated interventions for airway improvement, including conservative measures, tongue-lip adhesion (TLA), mandibular distraction osteogenesis (MDO), and tracheostomy. The primary outcome variable was complication rate, while predictor variable was the use of interventions for airway improvement. Results showed that conservative measures were the preferred initial management strategy in most studies, while TLA was recommended for infants with mild obstruction, and MDO or tracheostomy was reserved for severe cases. Only complications could be analysed via meta-analysis due to data heterogeneity, revealing that tracheostomy had a summary odds ratio of 5.39 in favour of TLA, while MDO had a ratio of 2.8 over TLA, and the complication rates were similar between MDO and tracheostomy. If conservative measures fail, the study recommends mandibular distraction as the preferable technique for stable airway improvement. If the infant is unsuitable for distraction, tongue-lip adhesion may serve as an alternative, while tracheostomy should be reserved for cases of severe multi-level obstruction. The authors propose that large-scale, multicentre trials comparing long-term outcomes are required to establish definitive guidelines.
