Psychosis: Goals of Pharmacotherapy

699
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Rheumatic Heart Disease III: Medical Management

539
Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

745
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

872
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Summary
This summary is machine-generated.

Diagnosing gout in elderly patients with polyarthritis can be challenging. When synovial fluid analysis is not possible, non-invasive imaging like ultrasound or DECT scans can help detect uric acid crystals.

Area of Science:

  • Rheumatology
  • Medical Imaging
  • Crystallography

Context:

  • Elderly patients with polyarthritis present complex diagnostic challenges.
  • Differential diagnosis includes autoimmune diseases, crystal deposition diseases, and infections.
  • Gout diagnosis typically requires identifying uric acid crystals in synovial fluid or tophi.

Purpose:

  • To explore alternative diagnostic methods for gout when arthrocentesis is not feasible.
  • To highlight the utility of non-invasive imaging in suspected gout cases.

Summary:

  • Arthrocentesis for synovial fluid analysis is the gold standard for gout diagnosis.
  • Inability to perform arthrocentesis necessitates alternative diagnostic approaches.
  • High-resolution musculoskeletal ultrasound and Dual-Energy CT (DECT) are valuable non-invasive tools for detecting monosodium urate crystals.

Impact:

  • Provides clinicians with alternative diagnostic strategies for gout in challenging cases.
  • Enhances the diagnostic accuracy of gout in elderly patients with polyarthritis.
  • Reduces the need for invasive procedures when contraindications exist.
