Résumé

PURPOSE: To investigate the effects of transplantation of a circumferentially-trephined autologous oral mucosal graft using a vacuum trephine on ocular surface reconstruction in patients with limbal stem cell deficiency. METHODS: Patients with a limbal stem cell deficiency who underwent transplantation of autologous oral mucosal graft performed by a particular surgeon in Seoul National University Hospital were included. The medical records of these five patients were retrospectively reviewed. The lower labial mucosal graft inside the inferior lip was trephined to a depth of 250 µm using a donor vacuum trephine with a 9-mm diameter. Outside markings were made using a 14-mm intraoperative keratometer. The oral mucosal graft was dissected under a microscope using a Beaver mini-blade as either a ring or a crescent-shaped strip with a 5-mm width. The mucosal graft was transplanted onto the limbus in the limbal-deficient eye. Best-corrected visual acuity and corneal status were measured during the follow-up period. RESULTS: Four patients were diagnosed with Stevens-Johnson syndrome and one was diagnosed with atopy-associated immune keratitis. The mean follow-up period was 10.4 ± 2.9 months. After 4 months, visual acuity improved in all patients, and the mean improvement in logarithm of the minimum angle of resolution visual acuity was 0.526 ± 0.470 (range, 0.15 to 1.10). Corneal surface erosion and neovascularization decreased in four patients, and stromal opacity decreased in two patients. The engraftments maintained ocular surface stabilization in four of the five patients at the last follow-up. CONCLUSIONS: Transplantation of circumferential autologous oral mucosal grafts may be effective for the treatment of limbal stem cell deficiency.

Résumé

PURPOSE: To report a case of eyeball displacement into the ethmoid sinus followed by early surgical intervention and good visual recovery. CASE SUMMARY: A 46-year-old female visited our hospital after she injured the right side of her face. Her visual acuity could not be measured and computed tomography revealed displacement of the right eyeball into the ethmoid sinus, as well as right medial orbital wall fracture and rupture of the right medial rectus muscle. She underwent surgical reduction of the herniated eyeball and surgical correction of the medial orbital wall fracture within 20 hours after the accident. Eighteen months after the surgery, visual acuity of the right eye improved from light perception to 20/28, and her color vision and visual field of the right eye improved to normal range. CONCLUSIONS: Displacement of the eyeball in the orbital wall fracture is very rare, and eyeball displacement into the ethmoid sinus is even rarer. We achieved good visual outcome through early surgical intervention. The early anatomical reduction of the displacement and wall fracture may promote improved final visual outcome in other similar cases.

Résumé

Clustered occurrences of ankylosing spondylitis (AS) in family have been noticed. We evaluated patients with AS confirmed by the modified New York criteria for familial history of AS (one or more first to third degree relatives). The clinical characteristics and the recurrence risks (number of AS patients/number of familial members) of the familial AS compared to sporadic AS were investigated. Out of a total of 204 AS patients, 38 patients (18.6%) reported that they had a familial history of AS. The recurrence risks in the familial AS patients for first, second and third degree family members were 14.5%, 5.2%, and 4.4% respectively. Erythrocyte sedimentation rate (ESR) (22.6+/-22.2 vs 35.4+/-34.4, P=0.029) and C-reactive protein (CRP) (1.24+/-1.7 vs 2.43+/-3.3, P=0.003) at diagnosis, body mass index (21.9+/-2.7 vs 23.7+/-3.3, P=0.002) and frequency of oligoarthritis (13.2% vs 33.7%, P=0.021) were significantly lower in the familial form. The presence of HLA-B27 (97.4% vs 83.1%, P=0.044) was significantly higher in familial AS. In conclusion, Korean familial AS patients show a lower frequency of oligoarthritis, lower BMI, lower ESR and CRP at diagnosis and higher presence of HLA-B27.
