Orbital cellulitis.

Orbital cellulitis is an emergency. It may cause blindness and progress to life-threatening sequelae such as brain abscess, meningitis and cavernous sinus thrombosis. Successful management is dependent upon urgent referral and immediate treatment. Although isolated eyelid erythema and swelling usually indicate primary infection anterior to the orbital septum, they may also be the first signs of an underlying frontal or ethmoidal sinusitis. The condition always requires emergency referral to both an ophthalmologist and otorhinolaryngologist.

Intracordal Teflon injection: a question of timing.

Intracordal Teflon injection is commonly performed for recurrent laryngeal nerve palsy. It is generally agreed that injection should not be performed for a period of six months from the onset of an 'idiopathic' paralysis. A case is presented in which recovery occurred late, after intracordal injection, with unfortunate results. Successful removal of the Teflon is described. The advisability of a longer wait before surgery for 'idiopathic' recurrent laryngeal nerve palsy is considered.

Latent mastoiditis: no room for complacency.

The administration of antibiotics in otitis media alters the natural course of the disease process. If the antibiotics used are inappropriate, or if dosage or duration of treatment is inadequate, an imminent intracranial complication may be masked. A case of latent mastoiditis presenting with Pott's puffy tumour is described.

Post-irradiation leiomyosarcoma of the maxilla.

Primary malignant smooth muscle tumours of the maxilla are extremely rare. A case of leiomyosarcoma of the maxilla associated with previous irradiation is presented. The aetiology, pathology and clinical aspects of this tumour are reviewed.

Morphological study of the fetal vasculature of the human term placenta: scanning electron microscopy of corrosion casts.

Microvascular corrosion casts of the fetal vessels of the normal human placenta were studied using the scanning electron microscope. All available evidence suggests that when prepared under standard conditions the resultant casts accurately replicate the original luminal morphology of the vessels, and are comparable between placentae. In conjunction with stereo-pair photography this technique allows for the rapid and unequivocal interpretation of the three-dimensional configuration of villous vasculature. Previously described structures such as dilated capillary loops and perivascular capillary networks can be viewed in new and dramatic perspective. It is hoped the technique may thus be of assistance to physiologists in the interpretation of experimental data concerning placental transport. Further work is in progress to apply the technique to the investigation of possible changes in fetal vasculature occurring in abnormal pregnancies.
