Objectives Medical cannabis (MC) has recently garnered interest as a potential treatment for neurologic diseases, including Parkinson’s disease (PD). A retrospective chart review was conducted to explore the impact of MC on the symptomatic treatment of patients with PD.Methods Patients with PD treated with MC in the normal course of clinical practice were included (n = 69). Data collected from patient charts included MC ratio/formulation changes, PD symptom changes after initiation of MC, and adverse events (AEs) from MC use. Information regarding changes in concomitant medications after MC initiation, including opioids, benzodiazepines, muscle relaxants, and PD medications, was also collected.Results Most patients were initially certified for a 1:1 (∆9-tetrahydrocannabinol:cannabidiol) tincture. Eight-seven percent of patients (n = 60) were noted to exhibit an improvement in any PD symptom after starting MC. Symptoms with the highest incidence of improvement included cramping/dystonia, pain, spasticity, lack of appetite, dyskinesia, and tremor. After starting MC, 56% of opioid users (n = 14) were able to decrease or discontinue opioid use with an average daily morphine milligram equivalent change from 31 at baseline to 22 at the last follow-up visit. The MC was well-tolerated with no severe AEs reported and low rate of MC discontinuation due to AEs (n = 4).Conclusions The MC may improve motor and nonmotor symptoms in patients with PD and may allow for reduction of concomitant opioid medication use. Large, placebo-controlled, randomized studies of MC use in patients with PD are required.
Objectives Cladribine is a selective and oral immunological reconstitution treatment, approved in Europe for very active multiple sclerosis (MS) with relapses. Aims were to assess the safety and effectiveness of cladribine in real-world setting, during treatment follow-up.Methods This was a multicentric, longitudinal, observational study with retrospective and prospective data collection of clinical, laboratory, and imaging data. This interim analysis reports data from July 1, 2018 (study onset), to March 31, 2021.Results A total of 182 patients were enrolled: 68.7% were female; mean age at onset was 30.1 ± 10.0 years, and mean age at first cycle of cladribine treatment was 41.1 ± 12.1; 88.5% were diagnosed with relapse-remitting MS and 11.5% with secondary progressive MS. Mean disease duration at cladribine start was 8.9 ± 7.7 years. Most patients (86.1%) were not naive, and median number of previous disease-modifying therapies was 2 (interquartile range, 1–3). At 12 months, we observed no significant Expanded Disability Status Scale score worsening (P = 0.843, Mann-Whitney U test) and a significantly lower annualized relapse rate (0.9 at baseline to 0.2; 78% reduction). Cladribine treatment discontinuation was registered in 8% of patients, mainly (69.2%) due to disease activity persistence. Most frequent adverse reactions were lymphocytopenia (55%), infections (25.2%), and fatigue (10.7%). Serious adverse effects were reported in 3.3%. No patient has discontinued cladribine treatment because of adverse effects.Conclusion Our study confirms the clinical efficacy and the safety profile of cladribine for treating MS patients with a long-term active disease in the real-world setting. Our data contribute to the body of knowledge of the clinical management of MS patients and the improvement of related clinical outcomes.
Objectives The aim was to develop a prototype of an application (app) that identifies the significance of discovered genes for further consideration in the treatment plan of patients with epilepsy (precision medicine).Methods MEDLINE was systematically searched for related publications from inception to April 1, 2022. The following search strategy was implemented (title/abstract): “epilepsy” AND “precision” AND “medicine.” The following data were extracted: genes, phenotypes associated with those genes, and the recommended treatments. Two other databases were searched to cross-check the retrieved data and add to the data: https://www.genecards.org and https://medlineplus.gov/genetics. Also, the original articles of the identified genes were retrieved. Genes with specific treatment strategies (ie, any specific drug to be selected or to be avoided and also any other specific therapies [eg, diets, supplements, etc]) were selected.Results A database of 93 genes, which are associated with various epilepsy syndromes and for which specific treatment strategies have been suggested, was developed.Conclusions A Web-based app (a search engine) was developed accordingly that is freely available at http://get.yektaparnian.ir/, GET (Gene, Epilepsy, Treatment). When a patient comes to the clinic with a genetic diagnosis and a specific gene is identified, the physician enters the gene name into the search box, and the app shows whether this genetic epilepsy needs a specific treatment. This endeavor would benefit from input by experts in the field, and the Web site should be developed more comprehensively.
Objectives This is a case series and a review of the literature of therapeutic outcomes of botulinum toxin (BT) injections for anterocollis.Methods Data collected included gender, age, age at onset, muscles targeted, and doses injected. Routine forms were filled out during each visit: Patient Global Impression of Change, Clinician Global Impression of Severity, Tsui scale. The effect duration and side effects (SEs) of the previous treatment were noted.Results We described 4 patients (3 men, 13 visits) with anterocollis, as primary postural abnormality of the neck, emphasizing the therapeutic response to BT injection. Mean age at onset was 75.3 ± 7.0 years, age at first injection was 80.7 ± 3.5 years. The mean total dose per treatment was 290.0 ± 95.6 units. Patient Global Impression of Change with any grade of favorable effect was reported in 27.3% of the treatments. In objective assessment, Global Impression of Severity and Tsui scores did not show a consistent tendency of improvement. Neck weakness was prevalent in 18.2% of the visits of the anterocollis group while no other SEs were noted. We found 15 articles describing experience with BT for anterocollis in 67 patients (19 in deep and 48 in superficial neck muscles).Conclusions This case series describes the poor outcome of BT treatment for anterocollis, with low efficacy and bothersome SE. Levator scapulae injection for anterocollis is not effective and is highly associated with head drop and should perhaps be abandoned. Injection to the longus colli might give some benefit in non-responders.
Objectives Oral cenesthopathy is an uncomfortable and bizarre oral sensation without corresponding organic findings. Although some treatment options, including antidepressants and antipsychotic drugs, have been reported to be effective, the condition remains refractory. Here, we report a case of oral cenesthopathy treated with brexpiprazole, a recently approved D2 partial agonist.Methods and Results A 57-year-old woman presented with a complained of softened incisors. Furthermore, she could not perform housework because of the discomfort. The patient did not respond to aripiprazole. However, she responded to a combination of mirtazapine and brexpiprazole. The visual analog scale score for the patient's oral discomfort decreased from 90 to 61. The patient's condition improved enough to resume housework.Conclusions Brexpiprazole and mirtazapine may be considered for the treatment of oral cenesthopathy. Further investigations are warranted.
Objective Research points to exercise having a positive effect in fighting relapse and use of drugs of abuse. Through conducting this research, differences have been observed in the effects of exercise on drug abuse between sexes. Many of the studies found that exercise tends to cause a more profound effect in blocking drug relapse or reinstatement in males when compared with females.Methods Our hypothesis is that these differences in response to drugs of abuse after an exercise regimen could in part be attributed to variations in testosterone levels between males and females.Results Testosterone has been shown to have a modulatory impact on the dopaminergic activity in the brain, causing an effect on the brain's response to drugs of abuse. Exercise has demonstrated a causal effect on increasing testosterone levels in males, whereas drugs of abuse decrease testosterone levels in males.Conclusions Thus, exercise raising testosterone levels in males helps to decrease the dopaminergic response in the brain to drugs of abuse causing attenuation to drugs. To find sex-specific exercise treatments for drugs of abuse, it is important to continue researching exercise's efficacy against drugs of abuse.
