Caterpillar setae-induced acute anterior uveitis: a case report.

PURPOSE: To report uveitis secondary to ocular penetration of caterpillar hairs (setae). METHODS: Case report. A documented attack of acute anterior uveitis was caused by initially overlooked penetration of caterpillar setae. RESULTS: A 66-year-old man presenting with unilateral hypertensive keratouveitis was treated with antiherpes simplex medication (along with local anti-inflammatory and cycloplegic agents) after anterior chamber paracentesis and serologic testing. Laboratory testing was negative. Resolution occurred after 5 days, and corneal clearing showed a predescemetic caterpillar seta. CONCLUSION: Patient history taken in an anterior uveitis setting should include gardening habits and searching for possible exposure to insects or arachnids.

Evaluation of biological stress markers in police officers.

This study was performed on 18 police officers, in order to evaluate relations between behavior and the activity of the main hormonal systems implicated in stress management. All subjects were male volunteers with more than 2 years on the job, a type A psychological profile according to Friedman and Rosenman, suffering from no mental or physical illness. The experimental setting used to study the role of different stress factors consisted of a series of tests that re-created stressful situations that the subject might encounter in his job. The study showed that during stressful states, not only did peripheral secretion of catecholamines increase, but that the ratio of epinephrine to norepinephrine was a determinant factor. Epinephrine secretion which was elevated at the beginning, decreased when the stressful situation was clarified or controlled, whereas norepinephrine secretion remained elevated as long as the subject had to remain alert. Cortisol secretion seemed to depend upon anticipation of the stressful event more than its actual happenning.

[Brown syndrome: current status].

PURPOSE: Brown's syndrome is a form of anatomical strabismus, or retraction syndrome. It is defined by active and passive limitation of upward gaze in adduction in the field of action of the inferior oblique muscle. The etiology of Brown's syndrome remains unknown. The defect lies at the level of the superior oblique's tendonis trajectory via the trochlea. We studied the frequency of clinical signs and results after surgery in patients presenting congenital Brown's syndrome. PATIENTS AND METHODS: Our study involved 18 children. They all underwent complete ophthalmological examination with orthoptic testing, pre and postoperatively. RESULTS: Neither sidedness nor predominance of sex was noted. Compensatory head posture was noted in 7 of 18 cases. Limitation of upward gaze in adduction was a constant finding, with a positive duction test. Eleven cases underwent superior oblique recession. Results of surgery were satisfactory, with resolution of compensatory head posture in over 80% of cases. CONCLUSION: The etiology of congenital Brown's syndrome remains unknown. The different surgical techniques give inconstant results. Operative indication is decided only when in the presence of well defined clinical manifestations: CHP, deviation in primary position with alteration of binocular vision.

Comparison of different materials for interposition arthroplasty in treatment of temporomandibular joint ankylosis surgery: long-term follow-up in 25 cases.

A variety of interposition materials have been used to prevent recurrence after arthroplasty in treatment of temporomandibular joint ankylosis. The purpose of this retrospective study of our experience was to compare the different materials (skin, temporal muscle, homologous cartilage) used for interposition arthroplasty over a period of 22 years. A total of 25 patients (32 joints) with at least 3 years of follow-up were included. Good results were achieved in 92% of cases using total full thickness skin graft and 83% of cases using temporal muscle flap. Homologous cartilage gave poor results.

The trabeculum as a drain in aphakic glaucoma.

Glaucoma of the aphakic patient is often difficult to treat. The authors present a new surgical technique which uses a portion of the trabeculum as a drain placed in the anterior chamber. Thirty eyes (19 aphakic and 11 pseudophakic) in 28 patients presenting refractory glaucoma were operated on by the same surgeon. Sixteen eyes had already undergone glaucoma surgery, 17 presented vitreous in the anterior chamber. The average postoperative follow-up was 18 months. Eighteen eyes (60%) needed no further treatment, 6 eyes (20%) were stabilized with a local treatment, 6 eyes (20%) remained hypertonic. This new surgical technique, which uses a portion of the trabeculum as a drain, allows for long-lasting filtration in the aphakic or pseudophakic patient with refractory glaucoma.

Ocular findings in children operated on for plagiocephaly and trigonocephaly.

Clinical examination of patients affected by plagiocephaly or trigonocephaly reveals evident malformation of the orbits, and the ocular repercussions are pronounced when children are operated on at an advanced age. Since it is generally accepted that binocular vision is fully developed by approximately 6 months of age, a late correction of plagiocephalic or trigonocephalic skull deformities may be an obstacle to the development of normal visual function. For the present report we investigated astigmatism and strabismus in 53 children, 39 of whom were operated on for plagiocephaly and 14 for trigonocephaly. Traction on the ocular globe induced by the bony deformation caused by the craniosynostosis may explain astigmatism and strabismus.

[Surgical follow-up and importance of information and consent on behalf of patients undergoing esthetic blepharoplasty].

INTRODUCTION: Plastic surgery of the eyelids aims to improve the cosmetic aspect while correcting either an excess of palpebral skin, or an orbital septum dehiscence with fat porf2p4on in the palpebral spaces, after evaluation of horizontal and vertical palpebral laxity. PATIENTS AND METHODS: The authors describe follow-up of upper and lower lid blepharoplasty by cutaneous and conjunctival approaches respectively, with case descriptions and a review of the literature. RESULTS: A "calendar" is made of the different phases of healings, to the final aesthetic aspect desired. DISCUSSION: The patients wishes as to technique and results of blepharoplasty must be discussed and understood. The surgeon must forewarn of eventual per and postoperative complications (hemorrhage, infection), but also the usual follow-up (hematoma, edema, scarring ...). This allows to avoid aggravation of the patients "legitimate" worrying when he/she looks in the mirror! CONCLUSION: The authors underline the importance of patient information concerning the pre and postoperative aspects of aesthetic blepharoplasty.

[Description of palpebral involvement in Fraser's syndrome].

GOAL: Fraser's syndrome is a rare multiple malformation involving the eyes, with cryptophthalmos. In its complete form, cryptophthalmos is a serious malformation with absence of eyelids and palpebral fissure. A review of ophthalmological signs is presented. CASE REPORT: A case of Fraser's syndrome is presented. Ophthalmological and somatic examination as well as evolution are described. RESULTS: Incomplete cryptophthalmos with symblepharon and bilateral palpebral coloboma are present. Surgical treatment with palpebral reconstruction allowed preservation of visual acuity in one eye. DISCUSSION: Ophthalmological signs are present in 93% of cases. Eyelid involvement such as symblepharon, and partial or complete coloboma are relatively frequent, whereas cryptophthalmos in its complete form are much more rare. CONCLUSION: Treatment involves palpebral reconstructive surgery in order to preserve visual function.
