Thus skin pigmentation may be the only manifestation in infancy, later to be followed by the development of skin tumours, skeletal and other abnormalities. The following case of neurofibromatosis is of interest in that it occurred in a newborn infant who presented with ski...

The temporal interval between flashing lights that is required to perceive nonsimultaneity decreases as the refractive error increases from 0 to +2 diopters. The interval then remains constant with further increases to 3 and 4 diopters. The results are discussed in terms of the relative increase of transient to sustained visual channels and of the increase in apparent movement.

Metastatic skin disease is an uncommon manifestation of visceral malignancies and failure to diagnose this early may result in incorrect treatment. Here, we report a 65-year-old man with bilateral painful eruptions on the abdominal skin and a past history of transitional cell carcinoma of urinary bladder.

Henoch-Shönlein purpura (HSP) is an acute, self-limited, systemic, small vessel vasculitis, that induces skin lesions, arthritis and abdominal pain. Palpable purpura is the most common manifestation in pediatric patients with HSP. We present an atypical case of HSP in a young patient and report successful treatment of the atypical skin lesions, while avoiding surgery.
