Muscle pain, also known as myalgia, is most commonly associated with sprains or strains. It frequently presents as redness at the site of injury, tenderness, swelling and fever. Muscle pain may occur as a result of excitation of the muscle nociceptor due to overuse of the muscle, viral infections or trauma. The most important endogenous substance released in response to the damaged tissues or nociceptor nerve endings in regards with muscle pain is adenosine triphosphate (ATP). Optimal pain management involves a combination of non-opioid, opioid analgesics, adjuvants, as well as non-pharmacologic strategies. Non-opiod analgesics include paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, which are indicated for mild to moderate pain. Whereas moderate to severe pain acquires opiod analgesics. This article provides an overview of muscle pain, the management and treatment thereof.
BackgroundThere is a high prevalence of human immunodeficiency virus (HIV), tuberculosis (TB), cancer and malaria in South Africa, and the drugs used to treat these conditions can be ototoxic. It is therefore important that healthcare professionals are able to identify and understand these drugs and their effects to ensure effective care of the patient.ObjectiveThis study aimed to assess the knowledge regarding pharmacotherapy-induced ototoxicity amongst final year, medicine, pharmacy, audiology and nursing students across South African universities.MethodsA descriptive cross-sectional study design was used, and data were collected via a self-administered online questionnaire. Non-probability purposive sampling was used to identify the participants at the universities which train audiologists, pharmacists, medical and nursing students.ResultsAn overall response rate of 41% (n = 720) was obtained. Sixty-four per cent (n = 461) of respondents were women (median age: 23 years). The majority of the respondents (95%) knew what pharmacotherapy-induced ototoxicity was, but a few (39%) knew the general signs and symptoms of ototoxicity. Furthermore, just less than half of the sample (48%) could identify the specific ototoxic medicines and the type of damage caused by this medication.ConclusionTo manage pharmacotherapy-induced ototoxicity effectively, a multidisciplinary healthcare team must have sufficient knowledge about ototoxicity. Therefore, efforts should be made to introduce extensively concepts of pharmacotherapy-induced ototoxicity into the undergraduate curricula of pharmacy, medical, nursing and audiology programmes.
This article aims to provide a concise, high-level overview of the classification, management and treatment of migraine. Migraine is a common, debilitating neurological disorder that is characterised by the presence of severe headaches, which may last anything from a few hours to a few days (4–72 hours). Thus, the condition is characterised by episodes of severe migraine headache, frequently accompanied by nausea and vomiting. These headaches may be unilateral or bilateral, and patients may also experience a range of associated features. Acute attacks require rapid, abortive treatment and the rate of recurrence needs to be reduced and managed using effective prophylactic measures.
Stevens-Johnson syndrome (SJS) is a form of toxic epidermal necrolysis (TEN) a rare but life-threatening hypersensitivity reactions that affect the skin and mucous membranes. The most common triggers are drugs, but they can also be triggered by infections. Granulysin has been recently identified as the major molecule responsible for the widespread keratinocyte necrosis. Early identification and removal of causative agent is crucial in preventing progression of condition and reducing patient mortality. Supportive care is often recommended over immunomodulating treatments as it helps improve patient outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
