Chemsex refers to the intentional consumption of specific substances, Gamma Hydroxybutyrate/Gamma Butyrolactone (GHB/GBL), Crystal Methamphetamine and/or Cocaine to facilitate or enhance the sexual experience. However, there was a plethora of associated problems ranging in severity to complex, life-threatening situations. Since its inception in 2014, The Club Drugs Clinic Ireland, the first outpatient-based clinic for GHB/GBL Detoxification in Ireland, had evolved to include managing problematic chemsex.

The Chemsex Working Group Ireland is a collaborative response from governmental and non-governmental agencies. Details of current medical and psychiatric management along with preliminary outcome findings on detoxification, relapse risk and associated factors will be presented.

Data collected include socio-demographic variables, gender and sexuality, detoxification setting, relapse history and attendance for counselling or aftercare. Descriptive analyses were conducted on referral counts, drug trends, success of first treatment episode, subsequent relapse rate, and uptake of counselling and aftercare.

There have been over 200 referrals to the Club Drugs Clinic Ireland. A number of predisposing and precipitating factors, contributed to the relapse rate (up to 70%) both in Ireland and internationally. The salutogenic, biopsychosocial-based model of addiction recovery produced the best outcomes. This integrated Dual Diagnosis Psychiatry, Sexual Health Medicine, Emergency Medicine and external services for a more comprehensive care.

The pattern of referrals reflects population trends in chemsex, despite the COVID-19 restrictions. While detoxification is largely successful, the high relapse rate highlights the challenge of maintaining abstinence. In order to competently address problematic chemsex, service coordination across various medical professions and ongoing monitoring of the substances consumed is quintessential.

People presenting with first-episode psychosis (FEP) have heterogenous outcomes. More than 40% fail to achieve symptomatic remission. Accurate prediction of individual outcome in FEP could facilitate early intervention to change the clinical trajectory and improve prognosis.

We aim to systematically review evidence for prediction models developed for predicting poor outcome in FEP.

A protocol for this study was published on the International Prospective Register of Systematic Reviews, registration number CRD42019156897. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance, we systematically searched six databases from inception to 28 January 2021. We used the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies and the Prediction Model Risk of Bias Assessment Tool to extract and appraise the outcome prediction models. We considered study characteristics, methodology and model performance.

Thirteen studies reporting 31 prediction models across a range of clinical outcomes met criteria for inclusion. Eleven studies used logistic regression with clinical and sociodemographic predictor variables. Just two studies were found to be at low risk of bias. Methodological limitations identified included a lack of appropriate validation, small sample sizes, poor handling of missing data and inadequate reporting of calibration and discrimination measures. To date, no model has been applied to clinical practice.

Future prediction studies in psychosis should prioritise methodological rigour and external validation in larger samples. The potential for prediction modelling in FEP is yet to be realised.

The benefit of mandibular advancement devices in patients with sleep-disordered breathing and as a potential option for obstructive sleep apnoea syndrome is well recognised. Their use in the setting of epilepsy or other seizure disorders is typically contraindicated.

A 48-year-old patient with a history of poorly controlled epilepsy and obstructive sleep apnoea syndrome was referred for ENT review for possible tracheostomy. The patient was wheelchair-bound with 24-hour continuous positive airway pressure, but sleep studies demonstrated persistent, severe episodes of apnoea and notable sleep disturbance. Sleep nasendoscopy demonstrated marked improvement on capnography with the laryngeal mask airway in situ, and this was maintained with mandibular advancement using jaw thrust following removal of the laryngeal mask airway. A mandibular advancement device was subsequently trialled; this had no subjective benefit for the patient, but the seizures resolved and control of apnoea was achieved with the combination of a mandibular advancement device and continuous positive airway pressure.

This paper highlights a novel application of mandibular advancement devices, used in combination with continuous positive airway pressure, which resulted in complete resolution of sleep deprivation and apnoea-induced epileptic events.

Anecdotally, infectious mononucleosis is considered a more severe infection than bacterial tonsillitis, requiring a longer hospital stay. However, there is little in the literature comparing the epidemiology of the two conditions. This study aimed to compare the epidemiology of bacterial tonsillitis and infectious mononucleosis, in particular any differences in the length of in-patient stay.

The hospital in-patient enquiry system was used to analyse patients admitted with bacterial tonsillitis and infectious mononucleosis between 1990 and 2009 inclusive.

There was a total of 3435 cases over the 20 years: 3064 with bacterial tonsillitis and 371 with infectious mononucleosis. The mean length of stay was 3.22 days for bacterial tonsillitis and 4.37 days for infectious mononucleosis. The median length of stay for each condition was compared using the Mann–Whitney U non-parametric test, and a significant difference detected (p < 0.001).

Patients with infectious mononucleosis have a significantly longer stay in hospital than those with bacterial tonsillitis.
