Medical student's note

Tinea pedis question 1. Does poor hygiene cause athlete’s foot? Athlete’s foot has nothing to do with cleanliness. Even if you wash your feet with soap and water several times a day, you can get athlete’s foot — especially if you don’t dry your feet completely after each washing. 2. Does walking barefoot lead to athlete’s foot? Walking barefoot in a locker room or public shower is one way to get athlete’s foot, but it’s not the only way. You can also become infected if you share a towel, socks, or shoes with someone who has athlete’s foot. 3. How can you tell if you have athlete’s foot? Athlete’s foot can look different in each person. Some people do get peeling or cracking skin between their toes. Others have redness or dryness on the bottom of their feet that looks just like dry skin. If you’re not sure what’s going on with your feet, see a podiatrist or doctor. 4. Can shoes and socks prevent athlete’s foot? The fungus that causes athlete’s foot thrives in dark, damp places. Wet shoe

Review on dermatomycosis: pathogenesis and treatment  Content: 1. Dermatophytes 2. ECOLOGICAL CLASSIFICATION 3. Trichophyton 4. Microsporum 5. Epidermophyton 6. DISTRIBUTION FREQUENCY OF DERMATOPHYTES AND DERMATOPHYTOSIS 7. PATHOGENESIS AND CLINICAL PRESENTATION 1. Dermatophytes a group of keratinophilic fungi thriving on the keratin substrate are the etiological agents responsible for causing cutaneous infections.  Dermatomycoses are infections of the skin, hair and nail caused as a result of colonization of the keratinized layers of the body . This colonization is brought about by the organisms belonging to the three genera namely  Trichophyton Microsporum Epidermophyton Infection may also be caused rarely by  the members of the genus Candida non-dermatophytic moulds belonging to the genera Fusarium, Scopulariopsis and Aspergillus 2. ECOLOGICAL CLASSIFICATION In the course of evolution these pathogens have developed host specificity.  ascribed to the difference in the composition of

Summary of the main points of pathophysiology in severe asthma 1. Pathophysiology? The key to improving targeted treatments, reducing disease burden and improving patient outcomes is a better understanding of the pathophysiology and mechanisms of severe disease. 2. Asthma Asthma is a complex interplay between airway inflammation and airway remodelling which results in airway hyperresponsiveness (AHR)—variable and excessive airway narrowing. Severe asthma is also often associated with some degree of fixed airflow limitation Th
