The Complex Role of Botulinum Toxin in Enhancing Goal Achievement for Post-Stroke Patients.

Introduction: The rehabilitation medical team is responsible for the therapeutic management of post-stroke patients and, therefore, for the complex therapeutic approach of spasticity. Considering the generous arsenal at our disposal in terms of both pharmacological treatment, through the possibility of administering botulinum toxin to combat spasticity, and in terms of accurate assessment through developed functional scales such as the GAS (Goal Attainment Scale), one of our purposes is to monitor the parameters that influence the achievement of functional goals set by patients together with the medical team in order to render the patients as close as possible to achieving their proposed functional goals, thus enhancing their quality of life. By assessing and establishing statistical and clinical correlations between the GAS and quantifiable parameters related to the affected post-stroke upper limb, namely degree of spasticity, motor control, pain level and evolution of pain under treatment with BoNT-A (abobotulinum toxin A), and patients' overall response to BoNT-A treatment, we aim to quantify the improvement of the therapeutic management of post-stroke patients with spasticity and develop a more personalized and effective approach to their disability and impairment.

Antimicrobial peptides as an argument for the involvement of innate immunity in psoriasis (Review).

Antimicrobial peptides (AMPs) are a group of oligopeptides found in most multicellular organisms with a capacity for rapid and nonspecific destruction of pathogens. The action of destroying pathogens is associated with a strong proinflammatory activity, stimulating the secretion of cytokines, chemokines, growth factors but also chemotaxis, the activation of dendritic cells and involving adaptive immunity also. The action of AMPs fits perfectly into the characteristics of innate immunity which makes these peptides candidates to be considered as an important element of this type of immunity.

Antidepressant effect of the interaction of fluoxetine with granisetron.

Selective serotonin reuptake inhibitors (SSRIs) may produce digestive side effects such as nausea and vomiting, diarrhoea and decreased appetite. These side effects are determined by the increase in serotonin availability at 5-HT3 receptors. Granisetron, a serotonin 5-HT3 receptor antagonist, is expected to antagonize the digestive adverse effects of serotonin reuptake inhibitors, but the question is to what extent granisetron influences the antidepressant effect of these substances.

Dermatology facing autoinflammatory syndrome.

Cutaneous symptoms are characteristic for the autoinflammatory disorders (AIDs), both in the classical autoinflammatory phenotype and in most disorders included in this syndrome, but they are not specific and inconstant. Several skin disorders (pyoderma gangrenosum and pustular acne) may be encountered either isolate or associated with autoinflammatory symptoms, forming well-defined clinical entities within the autoinflammatory syndrome. The high prevalence of cutaneous manifestations is an important characteristic of AIDs.
