Study Notes
Succinylcholine and Renal Failure
- Patients with renal failure face risks of hyperkalemia when receiving succinylcholine.
- Succinylcholine can induce bronchospasm typically within minutes of administration.
- Danger in renal failure arises due to the potential for prolonged neuromuscular blockade due to impaired drug metabolism.
- The term "myotoxic" describes succinylcholine effects in patients with renal failure.
- Anaphylactic reactions are particularly dangerous in patients on succinylcholine due to rapid onset and potential airway compromise.
Tinea Versicolor
- Tinea versicolor appears as hypopigmented or hyperpigmented patches on light-skinned individuals.
- Malassezia furfur is the fungus responsible for Cutaneous candidiasis.
- The growth of Tinea versicolor is dependent on humidity and oil secretion from the skin.
- Tinea versicolor primarily affects the trunk, shoulders, and arms.
Cutaneous Mycoses and Ringworm
- The primary source of infection for Cutaneous Mycoses caused by Ringworm is direct contact with an infected individual or animal.
- Under microscopic examination, hyphae and spores are typically observed for Malassezia furfur.
- Tinea corporis presentations include a ring-like, raised border, but other forms are not specifically associated, like candidiasis.
- Dermatophyte test medium (DTM) is commonly used to diagnose Cutaneous Mycoses due to Ringworm.
- Microscopic examination reveals septate hyphae and arthroconidia for diagnosing Ringworm infections.
- The culture uses cycloheximide to inhibit saprophytes while allowing dermatophyte growth.
Candida Albicans
- Candida albicans is a dimorphic yeast, capable of forming both yeast and mold forms.
- The oral cavity is the most commonly affected area by Candida albicans infections.
- A predisposing factor not mentioned for Candida infections is extensive physical trauma.
- In the mouth, Candida albicans typically causes oral thrush, presenting with white patches.
- Lesions caused by Candida infections are characterized as red, inflamed and often with white exudate.
Mycetoma
- Differentiating between actinomycetes and Madurella is crucial for accurate mycetoma diagnosis due to treatment implications.
- Mycetoma caused by fungi commonly exhibits a granular mass and fistula formation.
- Black granules in mycetoma are typically due to the presence of pigmented fungi.
- White, yellow, and red granules are significant in mycetoma diagnosis due to their association with specific causative agents.
- Compared to Madurella mycetomatis, Actinomycetes may produce a more purulent discharge.
- Itraconazole is commonly used to treat fungal mycetoma infections.
Microscopic Examination and Infections
- Under direct microscopic examination, Candida albicans shows pseudohyphae and yeast cells.
- Vulvovaginal candidiasis is commonly seen in diabetic women and those on prolonged antibiotics.
- Repeated immersion in water can lead to nail infections caused by weakened nail structure.
- The formation of a germ tube when spores are incubated with human serum is a test for Candida diagnosis.
- Fluconazole is typically used to treat systemic candidiasis.
- Subcutaneous mycoses like mycetoma are usually introduced into the body through trauma or skin breaks.
