Disseminated hydatid disease in a child: albendazole treatment of orbital cyst.

PURPOSE: Orbital hydatid cyst is rare and represents a small percentage of all echinococcal systemic locations. It is usually a primary echinococcosis. A new case of orbital hydatid cyst with asymptomatic coexistent lung and liver cysts is described in a child. METHODS AND RESULTS: The patient underwent surgical excision of the lung and liver cysts and successful application of albendazole treatment for orbital echinococcal cyst without evidence of recurrence after a 4-year follow-up. CONCLUSIONS: Hydatid cyst should be included in the differential diagnosis of unilateral exophthalmos in patients from countries where echinococcosis is endemic.

[Surgical results in childhood primary comitant large-angle exotropia]. / Résultats chirurgicaux des exotropies primitives concomitantes à grand angle chez les enfants.

INTRODUCTION: The purpose of this study was to evaluate the surgical results in childhood primary comitant large-angle exotropia (>30Delta) after a single operation and to analyze the factors that could influence these results. PATIENTS AND METHODS: We carried out a retrospective study in all children presenting with comitant primitive exotropia at an angle greater than 30Delta, who were operated on in our department from January 1996 to December 2000 by various surgeons. One hundred thirty-eight (138) cases were reviewed. The children with a substantial A or V phenomenon, retraction syndromes, nystagmus, those presenting with a neurological disease and those who had had previous eye surgery were excluded. The postoperative results were classified in three categories: residual exotropia over 10Delta, good postoperative result (esotropia<10Delta, orthotropia or exotropia<10Delta), and consecutive esotropia over 10Delta. RESULTS: Ninety-seven children fulfilled the study criteria. Forty (41.2%) were boys and 57 (58.8%) girls. The average age at the time of surgery was 6.5 years (SD 3.1). Sixty-eight of 97 (70.1%) had intermittent exotropia. Twenty-six children (26.8%) underwent a bilateral recession of the lateral rectus, 67 (69.1%) a unilateral operation, recession of a lateral rectus/resection of a medial rectus, and four (4.1%) an operation on three horizontal muscles. Sixty-nine percent of the children operated on had a good postoperative result, according to criteria defined in our study, 1 year after surgery. DISCUSSION/CONCLUSION: Childhood primary comitant large-angle exotropia can be corrected with a single surgical procedure, unilateral or bilateral, with a success rate which, in our study, reached 69%.

Cataract surgery in children with uveitis.

PURPOSE: To report the technique and postoperative results of cataract surgery in children with uveitis. METHOD: Between 1988 and 1998, nine children (age range: 2.5-11 years) who developed secondary uveitic cataract and underwent cataract extraction were studied retrospectively. Seven children had juvenile rheumatoid arthritis and two had chronic anterior uveitis of unknown etiology. The surgical technique was lensectomy and wide anterior vitrectomy with limbal approach, lysis of anterior synechiae and in some cases, peripheral iridectomy. Postoperative aphakia was corrected with soft contact lenses in all patients. Follow-up ranged from 6 months to 6 years. RESULTS: Postoperatively, visual acuity in all patients improved and final visual acuity ranged from 20/70 to 20/25. Significant intraoperative complications did not occcur in any patient. One boy with juvenile rheumatoid arthritis developed cystoid macular edema 1 month postoperatively, which was successfully managed. He also developed hypertonia 1 year later, which was also successfully managed. Seven of the nine children had fewer and milder relapses of uveitis after surgery. CONCLUSION: Cataract surgery, using the lensectomy-vitrectomy technique in children with uveitis, is a safe technique with a relatively small percentage of postoperative complications and good functional results.

Idiopathic intracranial hypertension in children.

We studied prospectively the etiology, clinical presentation, and outcome of idiopathic intracranial hypertension in 36 patients (20 boys and 16 girls) aged 3.5 months to 14 years. The etiology was identified in 28 (77.7%) patients. The most common predisposing factor was middle-ear infection, followed by obesity. Of the 36 cases seen, 26 presented with the classic picture of headaches, papilledema, and elevated cerebrospinal fluid pressure; 8 children had intracranial hypertension in the absence of papilledema and 2 had fundoscopic evidence of papilledema with normal cerebrospinal fluid pressure initially. In four children resolution of intracranial hypertension occurred with removal of the causative agent or appropriate treatment of the underlying condition. In 8 of 17 patients intracranial hypertension resolved with acetazolamide therapy and in 22 of 24 patients it resolved with corticosteroids in combination with acetazolamide. Subnormal visual acuity, narrowing of visual fields, or both were present on the initial examination in 10 patients; 2 of them, who presented with loss of vision, have permanent visual impairment. Four additional patients presented a transient, mild impairment of visual acuity during treatment. Our study confirms the wide clinical spectrum and the difficulties encountered in diagnosis of idiopathic intracranial hypertension. A wide variety of etiologic associations should be investigated to provide definitive therapy. Loss of visual function is the only serious complication.
