Abstract

Insights

Feline dermatophytosis, primarily caused by Microsporum canis, is most prevalent in Persian and related breeds, especially in young cats. Pruritus is a common symptom across all breeds.

Area of Science:

  • Veterinary Dermatology
  • Mycology
  • Epidemiology

Background:

  • Dermatophytosis is a common fungal skin infection in cats, often caused by Microsporum canis.
  • Predisposing factors include young age, long hair, and specific breeds like Persians.

Purpose of the Study:

  • To determine the prevalence of feline dermatophytosis in Italy over a nine-year period.
  • To identify breed-specific risk factors and clinical features of the disease.

Main Methods:

  • A retrospective study analyzed 1457 cats diagnosed between 2016 and 2024.
  • Diagnosis was confirmed via microscopy, Wood's lamp examination, and fungal culture.

Main Results:

  • The overall prevalence of dermatophytosis was 3.7%, with Microsporum canis identified in all cases.
  • Persian cats (21.2%) and related breeds showed higher prevalence compared to Domestic Shorthair cats (2.1%).
  • Young age (<1 year) was a significant predisposing factor, with contagion often occurring at breeder facilities.

Conclusions:

  • Persian and related breeds are disproportionately affected by dermatophytosis.
  • Young cats are highly predisposed to this fungal infection.
  • Pruritus is a frequent clinical sign, irrespective of breed.

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Confounding in Epidemiological Studies01:27

Confounding in Epidemiological Studies

Confounding in statistical epidemiology represents a pivotal challenge, referring to the distortion in the perceived relationship between an exposure and an outcome due to the presence of a third variable, known as a confounder. This variable is associated with both the exposure and the outcome but is not a direct link in their causal chain. Its presence can lead to erroneous interpretations of the exposure's effect, either exaggerating or underestimating the true association. This...

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
