Glued fixation of split-skin graft to the bony orbit following exenteration.

A technique is described to fix a split-skin graft to the bony orbit with a new homologous fibrin adhesive system. This shortens the time between the exenteration and the fitting of an epithesis to the bony orbit as compared with the granulation technique or fitting the graft with a prolonged pressure bandage. The advantages and risks connected to the glue system are discussed.

Lymphoid proliferations in the orbit: malignant or benign?

Clinical, pathological, and immunological analysis of 20 patients with ocular adnexal lymphoid disease has demonstrated several parameters which are useful for distinguishing malignant from benign lesions. Patients in the fourth or fifth decade of life presenting with an acute history of pain, oedema, epiphora, double vision, and ptosis, with a mass localised in the lacrimal gland area, are more likely to have a pseudolymphoma or a chronic inflammatory lesion than a true non-Hodgkin lymphoma (NHL). It is not possible to obtain a definite diagnosis without surgical intervention, because only three out of nine patients with orbital NHL had evidence of a monoclonal B cell population in peripheral blood on admission to the Orbital Centre. Furthermore it was confirmed that the identification of the various orbital lymphoid infiltrates becomes more distinct when immunological techniques are added to the clinical and histopathological methods of investigation. Multidisciplinary cooperation leads to further improvement of diagnosis and treatment of ocular adnexal lymphoproliferative disease.

Use of alumina, organic solvent or ion-exchange columns to purify samples for determination of catecholamines in urine.

We present two methods for the determination of free adrenaline, noradrenaline and dopamine by liquid chromatography and electrochemical detection. The catecholamines are isolated from the urine sample either by organic solvent purification by ion-exchange column and followed in both cases by adsorption onto alumina. Analytical recoveries and CV of both methods are investigated. Many chromatograms of catecholamines in urine are presented.

Pseudo-tumours, a clinical concept.

UNLABELLED: Space-filling lesions in the orbit can be divided into 3 large groups: 1. Acute and subacute inflammatory processes (bacterial, fungal, parasitic, foreign body). 2. Benign and malignant tumours, true new growths. 3. Pseudo-tumours. The conditions in group 3 are also space-filling lesions, but have the characteristics of a chronic, infiltrating, inflammatory process. In 11% of 340 consecutive patients in the Orbital Centre in Amsterdam this diagnosis was made. The group is far from uniform: the dominant cell type varies from one case to another. Usually lymphocytic cells are dominant; if these are arranged in follicles the lesion is called a pseudo-lymphoma. This condition can gradually leave the province of the pseudo-tumours and begin to show the characteristics of a malignant or non-Hodgkin lymphoma. Sometimes the inflammatory character of the lymphoid infiltration is dominant, as in myositis, sclerotenonitis and infiltrative Graves' ophthalmopathy; these conditions are clearly related to immunological processes. Attempts to classify all pseudo-tumours on a pathological basis have remained rather vague. CLINICAL PICTURE: rapid development (2-6 months); pain and oedema are present, but these are not the principal symptoms; secondary features are: disorders of motility, visual loss and other symptoms. Bilaterality usually indicates the presence of a systemic disease.

An orbital fistula complicating anaerobic frontal sinusitis and osteomyelitis.

A patient is described with an orbital fistula complicating frontal sinusitis and osteomyelitis of the frontal bone. The fistula was excised, but a fortnight later an acute exacerbation occurred. From the discharging pus a Staphylococcus aureus was cultured and from mucosa obtained during surgery a microaerophilic Streptococcus. These findings led to the diagnosis: synergistic bacterial inflammation of the frontal sinus, with osteomyelitis and orbital cellulitis.
