Alveolar soft part sarcoma of the tongue.

In this report a 13-year-old girl with characteristic clinical and pathological features of alveolar soft part sarcoma of the tongue is presented. Alveolar soft part sarcoma is a rare malignant tumor of unknown origin. Forty eight cases of alveolar soft part sarcoma have so far been reported in the head and neck region. Median survival reported for all sites of the body is 79 months following various modes of therapy. In this case, the treatment was surgical excision of the mass combined with radiotherapy and chemotherapy. The patient has been asymptomatic for the past 12 months.

Adolescent

Positional vertigo.

Different forms of positional nystagmus, particularly the continuous (type I) variety, were found in 86 consecutive patients admitted to general and neurological hospitals. This series is compared with 365 patients with paroxysmal (type II) and 23 patients with type III positional nystagmus. In this series of 32 of the patients with continuous type I positional nystagmus (including 15 patients with head injury) and 18 of the patients with paroxysmal type II nystagmus were found to have central lesions.

A comparison of methods of extra temporal facial nerve repair.

The development during the past 100 years of methods of repair of the divided facial nerve is discussed, from the early attempts to bring the nerve ends together inside a tube of vein. The success of the repair is enhanced by the care of the blood supply to the nerve and by measures to avoid scar developing between the ends of the nerve. Rest of the suture line is aided by the support of some form of tube, but unless this latter is kept below I cm. in length interference with the radial blood vessels to the nerve occurs. Intubation also encourages parallel growth of the nerve fibres and discourages fibroblast proliferation. Animal experimentation shows that the results when a soft silicone tube of special shape is used are superior to those obtained if the nerve is left free in the tissues, buried in muscle, or placed inside a vein.
