Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.6K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Drug Toxicity: Dose-Dependent Reactions

76
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

564
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Drug Toxicity: Allergic Reactions

80
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

519
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Peripheral Artery Disease IV: Nursing Management

517
 The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses,...

    Summary
    This summary is machine-generated.

    Dapsone treatment for dermatitis herpetiformis can cause peripheral neuropathy. Discontinuation of dapsone and supportive care led to symptom improvement and resolution of the neurological condition.

    Area of Science:

    • Neurology
    • Dermatology

    Background:

    • Dapsone is a common treatment for dermatitis herpetiformis.
    • Peripheral neuropathy is a potential adverse effect of dapsone therapy.

    Purpose of the Study:

    • To report a case of dapsone-induced peripheral neuropathy in a patient with dermatitis herpetiformis.
    • To describe the diagnostic findings and management of this condition.

    Main Methods:

    • A 24-year-old female patient developed symptoms of peripheral neuropathy while on dapsone.
    • Neurological examination, nerve conduction studies, and electromyography (EMG) were performed.
    • Dapsone was discontinued and alternative treatments were initiated.

    Main Results:

    • The patient presented with foot muscle weakness, claw hand deformity, and foot drop.
    • Nerve conduction studies confirmed a peripheral motor neuropathy.
    • Discontinuation of dapsone and initiation of cotrimoxazole, a gluten-free diet, and supportive therapy controlled the skin lesions and improved neurological symptoms.

    Conclusions:

    • Dapsone can induce peripheral neuropathy, even at standard doses.
    • Early recognition and discontinuation of dapsone are crucial for managing this adverse effect.
    • Multimodal treatment, including supportive care, can lead to significant recovery from dapsone-induced neuropathy.
