Malignant lymphoma of mucosa-associated lymphoid tissue of the lacrimal gland: case report and review of literature.

Mucosa-associated lymphoid tissue (MALT) lymphomas are increasingly recognized as a distinct clinical-pathologic entity among the non-Hodgkin's lymphomas. It usually presents as a localized disease process in extranodal tissues or organs such as stomach, salivary gland, thyroid gland, and not infrequently in orbital adnexa. Radiotherapy has an important role in the management, although long-term clinical results specifically addressing localized MALT lymphomas are lacking. We report a case of localized MALT lymphoma of the lacrimal gland, with successful treatment by radiation therapy (total dose 25 Gy) with 3 years of clinical follow-up. A review of the published literature was undertaken to assess the role of radiotherapy in the treatment of this disease involving orbital tissues, specifically, the lacrimal gland. Based on previous reports of patients with orbital lymphomas (low grade) and pseudolymphomas, of which many will now be recognized as MALT lymphomas, radiotherapy has an excellent local control rate and would be the treatment of choice. However, long-term results of pathologically confirmed cases of MALT lymphomas need further study because occasional relapses at distant sites can occur.

Cyanoacrylate tissue adhesive in blepharoplasty.

This article reports the results of an animal study designed to evaluate the usefulness of butyl 2-cyanoacrylate (Histoacryl) in blepharoplasty skin closure. Bilateral upper and lower lid blepharoplasty skin incisions were made on seven pigs. We compared the wounds closed with 6.0 nylon to those closed with Histoacryl at 1, 2, 4, and 9 weeks postoperatively. The tensile strength of the "glued" incisions was significantly greater than that of the sutured incisions only at the 9-week postoperative interval (p < 0.05). There was no significant difference in bond strength, however, between the two methods at 1, 2 and 4 weeks postoperatively. Histopathologic analyses of sutured and glued wounds were compared at the same designated postoperative periods. No deleterious effects were found in the overall healing of the cutaneous wounds closed with Histoacryl.

Treatment of blepharospasm and hemifacial spasm with botulinum A toxin: a Canadian multicentre study.

Botulinum A exotoxin was recently approved for use in Canada. We describe the efficacy of botulinum toxin in the management of 235 patients with blepharospasm (mean age 64.3 years) and 130 patients with hemifacial spasm (mean age 60.4 years) treated at three Canadian ophthalmologic centres between 1984 and 1989. A total of 98% of the patients with blepharospasm and 100% of the patients with hemifacial spasm had significant relief of their symptoms; however, 11% of the former and 2% of the latter did not respond to the usual starting concentrations of the drug and needed stronger dosages for relief. The duration of relief varied widely in both groups. Up to 7% of patients had ineffective treatments but responded to subsequent injections. Analysis of variance and linear trend statistics showed that there were no changes in the mean duration of relief over the first several treatments for individual patients in either group. Side effects were transient and included ptosis, exposure keratitis, epiphora and strabismus.

Lacrimal catheterization.

A new atraumatic technique for identifying the medial cut end of a surgically lacerated canaliculus is described. It offers the advantage of allowing the surgeon to pass a stent through the canaliculus only, without surgically manipulating the lacrimal sac or nasolacrimal duct or damaging the ipsilateral canaliculus.

Sophisticated radiology in otolaryngology. II. Diagnostic imaging: non-roentgenographic (non x-ray) modalities (ultrasound, nuclear medicine, thermography).

Newer forms of radiologic diagnostic imaging now include non-roentgenographic modalities such as ultrasound, nuclear medicin, and thermography, all of which can be applied to otolaryngology. It is the purpose of this presentation to demonstrate these modalities, and indicate their clinical application, yet in its earliest stages, to otolaryngology.
