SARCOPENIA

This is defined as age-related decline in skeletal muscle mass with low muscle strength and physical performance. Apart from ageing, it is a result of illness, sedentary lifestyle and poor diet. It is associated with increased disability, poor hand-grip strength, slow walking speed, susceptibity to infection, falls and fracture risk. In the presence of obesity, there is an increased impact on musculoskeletal and cardiometabolic health. Treatment strategies include exercise, especially resistance training, protein supplements in diet and vitamin D.

Scabies

Clinical features

  • Intense itching (worse with warmth and at night)

SCROTAL PAIN

Serious problems include testicular torsion, strangulation of an inguinoscrotal hernia, a testicular tumour and a haematocele, all of which require surgical intervention. A varicocele can cause discomfort—examine in standing position.
