- Abstract
Opioid use and associated morbidity and mortality have increased in several countries during the past 20 years. We performed a study whose objective was to assess the frequency and causes of opioid-related emergency division (ED) visits in an adult tertiary Swiss University Hospital over 9 weeks in 2018. We primarily assessed opioid-related adverse drug reactions (ADR), secondary overdose, misuse, abuse, and insufficient pain relief. Current opioid use was identified in 1037 (8.3%) of the 12 470 included ED visits. In 64 opioid users, an ADR was identified as a contributing cause of the ED visit, representing 6.2% of opioid users, and 0.5% of the total ED visits. Moreover, we identified an overdose in 16 opioid users, misuse or abuse in 19 opioid users, and compatible withdrawal symptoms in 7 opioid users. After pooling all these events, we conclude that the ED visits could be related to opioid use in 10.2% of opioid users. Finally, in 201 opioid users, insufficient pain relief (pain not responding to the current pharmacological treatment) was identified as a contributing cause of ED visits. In these cases, other factors than simply pharmacological nonresponse may have been involved. In the context of an ever-increasing opioid use to better control chronic pain situations, these results should reinforce emergency network epidemiological surveillance studies at a national level., (© 2022 The Authors.

5. [Acute pain management in opioid-maintained patients].

- Abstract
Treatment of acute nociceptive pain in patients with opioid substitution therapy (OST) is an actual topic. The clinical features of this population, as pain sensibility, and the pharmacological features of OST, require an individualized care which must be adjusted to the patient's pain and the OST used. This article offers a summary of the main possible pharmacological strategies by highlighting the features of pain in these patients and removing the barriers to an effective management. Generally, the OST is kept and a multimodal analgesia is added according to the intensity of the pain. Multimodal analgesia includes non pharmacological measures, non opioid drugs and/or opioid drugs which must be chosen according to the OST. Collaboration between different health professionals provides an effective management of pain in order to protect this vulnerable population from the negative health consequences of an insufficiently relieved pain., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

- Abstract
Introduction and Aims: In France, the law states that any person held in custody could be examined by a doctor. The main objective of the medical examination is to give medical evidence of health compatibility with custody. This review identifies health risks such as addictive behaviour. We wanted to know which psychoactive substances are used in this particular population, and how problematic these uses are., Design and Methods: A prospective, monocentric, open-ended study conducted via a structured questionnaire was carried out on detainees who reported having taken drugs or illegal substances. Practitioners investigated desired effects for each substance, and characteristics of use, by means of the dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994). Problematic use was assessed when at least 3 items of the DSM IV were positive., Results: 604 questionnaires were examined. 90.7% of questionnaires reported tobacco use, 76.2% cannabis, 57.3% alcohol, 12.5% psychostimulants, 10.0% opiates and 0.7% benzodiazepines or Z-drugs. The frequency of problematic use was 74.6% for opiates, 44.9% for cocaine and 25.3% for cannabis. Compared to non-problematic users, problematic users were older, more likely to be jobless without financial means, more likely to have a medical history, including a greater likelihood of mental illness, and more chance of undergoing prescribed medical treatment. They included more women and more homeless people., Discussion and Conclusions: These results show characteristics of psychoactive substance use in a sample of people in custody. Psychoactive substances mentioned by respondents are not different from those observed in the general population, but for certain users, the desired effects are far from the pharmacologically expected ones. For some, taking substances seems to be part of their way of life, for others it is a means to compensate for an underlying feeling of uneasiness. Furthermore, problematic users present severity criteria which seem to be greater than in psychoactive substance users in the general population., (Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

- Abstract
Background: The use of analgesics can lead to cases of drug abuse and dependence. It can also cause pseudo-addiction in patients suffering from pain. What is the actual situation in patients suffering from severe sickle-cell disease, exposed to acute pain during vaso-occlusive crises? Evaluation of the use of analgesics, on the basis of Diagnostic and Statistical Manual of Mental Disorders criteria for substance abuse and dependence, makes it possible to differentiate the symptoms occurring only in a context of pain, in the aim of managing the pain, and thus describing pseudo-addiction, from symptoms also occurring when there is no pain, and more in favour of true addiction. Currently there is no data available in France on this problem, and no studies have been carried out in children or adolescents with sickle-cell disease. The purpose of the study is to evaluate the prevalence of problematic use of equimolar mixture of oxygen and nitrous oxide and other analgesic drugs in a population of subjects with severe sickle-cell disease in France., Methods/design: PHEDRE (Pharmacodépendance Et DREpanocytose-drug dependence and sickle-cell disease) is an observational, descriptive and transversal study. Patients under the age of 26 with sickle-cell disease are included in the study by the doctors looking after them in sickle-cell disease centres. The patients are then contacted by a trained researcher for a telephone interview, including an evaluation of the Diagnostic and Statistical Manual of Mental Disorders criteria for abuse and dependence to equimolar mixture of oxygen and nitrous oxide and for each of the analgesic drugs taken by the patient. The data are also completed using the subject's medical record., Discussion: This study will make it possible to provide an initial quantitative and qualitative evaluation of problematic use of equimolar mixture of oxygen and nitrous oxide and analgesic drugs in the sickle-cell disease population. The results will be used firstly to provide additional data essential for monitoring the risk of overdose, abuse, dependence and misuse of these products, and to begin awareness-raising and to provide information for health care professionals, in order to significantly improve the management of sickle-cell disease-related pain., Trial Registration: Clinical Trials.gov ID: NCT02580565 registered 16 October 2015 Unique Protocol ID: RC14_0344.

- Abstract
Self-injection of high-dose buprenorphine is responsible for well-described complications. In 2011, we have been alerted by unusual but serious cutaneous complication among injection buprenorphine users. A prospective data collection identified 30 cases of necrotic cutaneous lesions after injection of filtered buprenorphine solution, among which 25 cases occurred following injection of buprenorphine generics. The main goal of our study was to put forward particularities that could explain the cutaneous complications, by qualitatively and quantitatively confronting particles present in Subutex and generics solutions. We used the same protocol that injected-buprenorphine users: generic or subutex tablets were crushed in sterile water and filtered through 2 filters commonly used (cotton-pad and sterifilt). Solutions were analyzed by laser granulometry, flow cytometry and scanning electron microscopy. We have highlighted the wide variation of the quantity and the size of the particles present in solution between the two drugs after cotton-pad filtration. The proportion of particles <10 µm is systematically higher in the generic solutions than with Subutex. All of the insoluble particles found in generic solutions contain silica, whereas non- organic element was to be identified in the insoluble particles of Subutex. One skin biopsy obtained from one patient who developed a necrotic lesion after intravenous injection of filtrated solution of buprenorphine generic, shows non-organic elements. Identification of particles in situ enables us to confirm the presence of silica in the biopsy. Actually the monitoring of patient receiving generic of buprenorphine must be strengthened.
