A Clinical Study of Severe Head Injury

This report is made to investigate clinical outcome in 144 patients with severe head injuries. The result was as follows: 18% made a good recovery, 25% were moderately disabled, 11% were left vegetative, and 44% died. The outcome from severe head injuries seemed to become worse with advancing age. It was observed that the prognosis for head injury in general worsens in the group older than 30 years and the apparent increased morbidity and mortality with a surgical hematoma relate more to age than to the presence of the hematoma.

A Case of Large Dermoid Cyst

The authors describe a case of large dermoid cyst of the scalp which removed surgically and cosmetically. Dermoid cyst is derived from epiblastic cells predestined to form skin which become detached from their neighbours and included in mesenchyme at about third to the fifth week of feral life, when the neural tube is closing. The contents of the cyst are thus mixtures of keratin, sebum, and hair, according to the proportionate development of these elements. It is usually a single tumor and may develop almost anywhere in the subcutaneous tissue, being of variable size.
