Journal of the American Academy of Dermatology
|June 1, 1985
Summary
Pseudomonic acid cream is effective for treating superficial skin infections. Clinical studies show high clearance rates with minimal side effects, making it a promising antimicrobial agent.
Area of Science:
- Dermatology
- Microbiology
- Pharmacology
Background:
- Pseudomonic acid is a novel, broad-spectrum antimicrobial agent.
- Topical formulations require adequate skin penetration for efficacy.
- Systemic administration in animals indicated rapid metabolism and elimination.
Purpose of the Study:
- To evaluate the efficacy and safety of a 2% pseudomonic acid cream for superficial skin infections.
- To assess the skin penetration and sensitization potential of the formulation in humans.
Main Methods:
- Animal studies were conducted to assess skin penetration and pharmacokinetic properties.
- Human volunteers were tested for sensitization to the cream.
- An open clinical study involved 68 patients with superficial skin infections treated with the cream thrice daily for 5 days.
Main Results:
- The 2% pseudomonic acid cream demonstrated adequate skin penetration in animal models.
- No sensitization was observed when applied to human skin.
- In the clinical study, 50 out of 68 patients achieved complete infection clearance within 2 days post-treatment.
- Significant clinical improvement was observed in 16 additional patients.
Conclusions:
- Pseudomonic acid cream is a safe and effective treatment for superficial skin infections.
- The formulation exhibits good tolerability and high efficacy rates.
- Further investigation into its therapeutic potential is warranted.

01:18Surface Membrane Barriers
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:28Gene Regulation in Microbial Communities: Quorum Sensing
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
