Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2 (COX-2),...

COPD: Management Using Bronchodilators and Corticosteroids

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids

Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

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

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

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 Disease...

Area of Science:

Otolaryngology
Vocal fold pathology
Minimally invasive procedures

Background:

Vocal fold polyps can cause significant dysphonia.
Traditional treatments like microlaryngoscopic surgery carry risks and may require longer recovery.
There is a need for less invasive and equally effective treatment options.

Purpose of the Study:

To assess the effectiveness and applicability of percutaneous corticosteroid injection for vocal fold polyps.
To detail the advantages and limitations of this technique in managing vocal fold polyps.

Main Methods:

A prospective case series involving 24 patients with vocal fold polyps.
Percutaneous corticosteroid injection performed under topical anesthesia.
Postoperative evaluation using stroboscopy, GRBAS scale, Voice Handicap Index, and phonatory function tests.

Main Results:

Successful completion in 22/24 patients with no complications.
Overall response rate of 91% and complete remission in 59% of patients.
Significant improvements in dysphonia (GRBAS), voice quality (VHI), and objective phonatory measures (MPT, jitter, shimmer, NH ratio).

Conclusions:

Percutaneous corticosteroid injection is a viable and effective treatment for vocal fold polyps.
The procedure is minimally invasive with low morbidity.
It presents a simple, cost-effective alternative to microlaryngoscopic surgery.
