Surgical approaches to cavernous haemangiomas of the orbit.

Cavernous haemangiomas are the most common orbital masses and the second most common cause of unilateral proptosis after thyroid ophthalmopathy. We retrospectively analysed 19 patients with retrobulbar cavernous haemangiomas, 9 of whom had lateral orbitotomy to remove retrobulbar cavernous haemangiomas located superior (n=4), inferior (n=2) or lateral (n=3) to the optic nerve. Seven patients had lateral orbitotomy together with an anterior medial approach to gain access to retrobulbar cavernous haemangiomas located medially to the optic nerve in the posterior half of the orbit. An anterior approach was used in 3 patient with an anteriorly located cavernous haemangioma. We describe here the planning of surgical treatment based on the site of the lesion.

Primary intraosseous hemangiomas of the orbit.

INTRODUCTION: Primary intraosseus orbital hemangiomas are rare vascular anomalies, of which only 23 cases have been previously reported in the literature. We here describe a further two cases. MATERIALS AND METHODS: An anterior approach was used to remove a mass located in the inferior orbital rim in one case, and in the orbital floor in the other. RESULTS: Good restoration of the orbital walls with no signs of recurrence. DISCUSSION: Intraosseous hemangiomas of the orbit are usually located anteriorly, and can be removed by anterior surgical approaches. The main surgical problem is due to the removal of the involved areas of the orbital walls because resection without reconstruction may cause functional impairments and secondary deformities that are more damaging for the patient than the tumour itself. In order to avoid defects, the integrity of the orbital walls must be immediately restored by means of autologous bone or alloplastic grafts.

Conservative treatment of arteriovenous malformations of the mandible.

A modified technique is reported on the treatment of arteriovenous malformations in the mandibular body. The technique consists of highly selected embolization and piecemeal removal of the lesion through burred holes made in the cortex. This way the mandible and the teeth may be saved in selected patients.

Reconstruction of the orbital walls in surgery of the skull base for benign neoplasms.

Surgery for benign neoplasm extending into the orbital roof requires immediate reconstruction to avoid complications, which include transmission of the cerebral pulse to the globe, bulbar dystopia, diplopia, and fibrosis of the oculomotor muscles. Many alloplastic materials have been employed for such reconstruction, but currently most authors agree that autologous bone graft is the best option. Using calvarial bone in adults and split ribs in children, we have operated on eight patients for fibrous dysplasia (five cases), neurofibroma (two cases), or meningioma (one case). After a median follow-up period of two years and six months, good morphology of the orbit was maintained with no ocular symptoms.

[Dispersion of junctional tissue and its consequences in a case of sudden infant death].

This article reports a case of sudden infant death syndrome in a 1-month-old male. Some important abnormalities of the cardiac conduction system were found, consisting of persistent fetal dispersion of the atrioventricular node and His bundle, accessory atrioventricular pathways of Mahaim type and resorptive degeneration. These changes could be considered as a morphological substrate for cardiac arrhythmias.

Penetration of cefonicid into serum, salpinges, cervix and vaginal tissue.

Cefonicid is a new cephalosporin that, given in adequate concentrations is able to kill some pathogens such as Gram-positive cocci and many Enterobacteriaceae. In this study we have evaluated 40 patients receiving 1 g of cefonicid i.m. at various times before abdominal or vaginal hysterectomy. The results of the present study indicate that a single dose of 1 g of cefonicid given intramuscularly is useful as prophylaxis and treatment of gynecological infections.
