Long-term Cannabis-based oil therapy and pain medications prescribing patterns: an Italian observational study.

OBJECTIVE: Chronic pain is one of the most common medical conditions in developed countries. The 2020 Italian National Report on Medicines shows how, in the last years, there was a light but constant increase in the prescription of pain medications. The purpose of our study was to assess the effects of long-term cannabis-based oil consumption on the distribution of patients with analgesics prescriptions for chronic pain in a Pain Medicine Unit in Northern Italy. PATIENTS AND METHODS: This is a retrospective, observational study in which patients treated with long-term medical cannabis-based oils, followed between June 2016 and July 2019, were enrolled. The effects of cannabis-based oil consumption on the distribution of patients with pain medications, before and after its long-term use, were evaluated with a Related Samples McNemar Test. Subgroups analyses were performed based on sex, age, comorbidity, duration of cannabis treatment, and condition driving cannabis prescription. RESULTS: A significant difference in opioid non-users after a long-term cannabis-based oil therapy was identified (from 32.1% to 55.4%, p = 0.0023), while no significant differences were found in the distribution of anticonvulsant, antidepressant, and benzodiazepine users. A high benzodiazepine use prevalence was revealed, while subgroup analyses showed increased antidepressant use in people over 65 years old (from 93.7% to 56.2%; p = 0.0313). CONCLUSIONS: Pain medication patterns of prescribing show how necessary it is to improve prescription practices among chronic pain patients. Opioid-sparing medications represent a crucial aspect of the pain treatment process, along with deprescribing protocols. Clinicians and clinical pharmacologists must cooperate to meet the need of a guide that can represent the most possible appropriate therapy for these patients.

Chronic, acute and acute-on-chronic pain prevalence in a tertiary care hospital setting.

OBJECTIVE: The aim of the study was to develop appropriate pain therapy and prevention plans; pain needs to be understood in terms of prevalence and associated predictor factors in hospital and primary care. The purpose of our research was to assess the prevalence of chronic, acute, and acute-on-chronic pain, and ascertain the effects of several factors on the likelihood of pain in an Italian Tertiary Care Hospital. PATIENTS AND METHODS: This is a prevalence study in which the primary outcome was the prevalence rate of chronic pain inpatients. Fisher's exact tests and binomial logistic regression were performed for the prevalence measures, and to ascertain the effects of Hospital Unit, sex, age, surgery and preexisting chronic pain on the likelihood of pain during the hospitalization, respectively. RESULTS: Chronic pain was reported in one-fifth of inpatients [21.7% (95% CI: 0.1764, 0.2625)], with a high prevalence of pain-related interference on sleep and emotional status. Nearly 70% of chronic pain patients accused acute-on-chronic pain [15.3% (95% CI: 0.1178, 0.1934)]. High pain prevalence rates were assessed at the time of the interview (37.3%; 95% CI: 0.3234, 0.4239) and in the last 24 hours of hospitalization (53.3%; 95% CI: 0.4814, 0.5850). A 2.7 and 2.6 higher odds to suffer from pain during the hospitalization were associated with surgery, and preexisting chronic, respectively. CONCLUSIONS: This study raises awareness of the necessity to refine pain assessment and management in hospital and outpatient services. The promotion and enhancement of hospital-territory integration are essential for improving pain prescribing practices and increasing patient safety.

Prescribing cascades and medications most frequently involved in pain therapy: a review.

OBJECTIVE: The aging of the population and chronic pain represents topical issues in developed countries. These often translate into polypharmacy, inappropriate medications, and adverse drug events, with the risk of misinterpreting these latter with new medical conditions, generating what is referred to prescribing cascade. Prescribing cascades may lead to the prescription of new drugs, which could cause new potential side effects and unnecessary costs for individuals and healthcare systems. Therefore, the purpose of our review was to collect a good deal of prescribing cascades examples involving pain therapy medicines, to help clinicians minimize drug-related clinical outcomes. MATERIALS AND METHODS: We search in MEDLINE database through PubMed, including 31 studies and 80 different examples of prescribing cascades. RESULTS: The medications most commonly resulting in the initial drug therapy prescribed were represented by psychoanaleptics (27/80, 33.7%). Among adverse drug events, the most common one, misinterpreted as a new medical condition, was represented by tremor and extrapyramidal symptoms (20/80, 25%). As regards the new drug therapies prescribed for adverse drug events, the therapeutic subgroups most commonly resulting in the new drug therapy prescribed were represented by psycholeptics (12/80, 15%), and by anti-Parkinson drugs (12/80, 15%). CONCLUSIONS: This study provides a list of several examples of prescribing cascades in pain medicine and is essential to raise awareness of the potential dangers they could involve in all patient populations. Collaboration between clinicians and clinical pharmacologists may lead to more appropriate polypharmacy schemes.

[Severe and prolonged post-dural puncture headache: from pathological basis to therapeutic role and correct timing for epidural blood patch]. / Cefalea da deliquorazione grave e protratta: dal riconoscimento del substrato organico al ruolo terapeutico e alla corretta temporizzazione del blood patch peridurale.

Believed to be due to unbalance between cerebrospinal fluid (CSF) production rate and its loss through the spinal dural puncture hole, post-dural puncture headache (PDPH) is often considered as a physiological syndrome, usually reversible without pathological sequelae after dural hole's closure. The clinical case here presented (incapacitating headache associated with diagnostic dural puncture in a leukaemic young female patient who underwent bone marrow transplantation) shows potentially fatal pathological sequelae following prolonged headache (untreated, due to the severe postransplant immunodeficiency and coagulopathy). The observed RMI lesions suggest interesting conclusions about the clinical indications and correct timing of autologous epidural blood patch (EBP). We also suggest the ways to preventing rebound intracranial hypertension following autologous epidural blood patch in patients suffering from incapacitating and prolonged headache.
