Summary
Scabies, a worldwide skin infestation, is prevalent in Singaporean institutions. Early diagnosis and treatment are key to managing outbreaks of classic and crusted scabies.
Area of Science:
- Dermatology
- Infectious Diseases
- Public Health
Background:
- Scabies is a common global parasitic skin infestation.
- It affects all ages and socioeconomic groups.
- In Singapore, scabies outbreaks are more frequent in institutional settings.
Purpose of the Study:
- To outline the epidemiology and management of scabies in Singapore.
- To highlight diagnostic approaches and treatment protocols.
Main Methods:
- Diagnosis relies on visual inspection and clinical examination.
- Skin scrapings for microscopy confirm scabies mites, eggs, or feces.
- Treatment strategies vary for classic and crusted scabies.
Main Results:
- Two variants exist: classic and crusted scabies, with crusted scabies having a higher mite burden.
- Early identification, isolation, and contact prophylaxis are crucial for outbreak control.
- Microscopy confirms the presence of scabietic elements.
Conclusions:
- Effective scabies management requires prompt diagnosis and targeted treatment.
- Topical malathion or permethrin are standard for adult scabies.
- Crusted scabies necessitates a combination of topical permethrin and oral ivermectin.

485
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
