Neurilemoma of the Bulbar Conjunctiva: Report of One Case

PURPOSE: To report one case of neurilemoma of the bulbar conjunctiva with a review of the relevant literature. CASE SUMMARY: A 15-year-old girl presented with a bulbar conjunctival mass in the right eye. There were no other medical or ophthalmologic problems. The patient wanted to remove the mass for cosmetic reasons. We performed an excisional biopsy and simple wound closure. The mass was composed of bipolar spindle shaped cells that were arranged in bundles and fascicles in dense fibrous tissue. Immunohistochemical staining for the S-100 protein was positive. Two months after mass excision, there was no evidence of recurrence. CONCLUSIONS: We successfully treated a case of bulbar conjunctival neuriliemoma by simple excision.

Changes of beta-Adrenergic Receptor mRNA in the Visual Cortex and Superior Colliculus of Monocular Deprivated Rat

PURPOSE: To investigate the change of the Beta adrenergic system in the rat visual cortex and superior colliculus after visual deprivation during a critical period of postnatal development. METHODS: The changes of beta 1 and beta 2 adrenergic receptor mRNA were investigated by using northern blot analysis in the rat visual cortex and superior colliculus. The right eyelid of visually deprived rat was sutured at the 10th postnatal days. After visual deprivation for 4 weeks, the rat were sacrificed and the visual cortex and superior colliculus tissues were removed for analysis. RESULTS: Beta 1 and beta 2 adrenergic receptor mRNA expression was decreased in the contralateral visual cortex to the deprived eye. In the superior colliculus, beta 2 adrenergic receptor mRNA expression increased in both sides, but a much greater increase was shown in the ipsilateral superior colliculus than the contralateral side. CONCLUSIONS: These results suggests that visual deprivation during a critical period of postnatal development influences the beta adrenergic system in the rat visual cortex and superior colliculus.

A Case of Endophthalmitis Associated with V. Vulnificus Septicemia

PURPOSE: To report a case of endophthalmitis associated with Vibrio vulnificus septicemia. METHODS: Vibrio vulnificus septicemia patient was referred to us in consultation for abrupt onset left visual loss, severe periorbital swelling and conjunctival injection. RESULTS: Left eye showed suppurative intraocular inflammation. With a clinical impression of V. vulnificus endogeneous endophthalmitis, culture for causative organisms and intravitreal antibiotics injection were done. Two days later, we performed pars plana lensectomy, pars plana vitrectomy, intravitreal antibiotics, SF6 gas injection. Intraocular inflammation was subsided after operation, and the anatomical structure of the eyeball was preserved CONCLUSIONS: Immediate ophthalmologic examination is mandatory for ruling out endophthalmitis when Vibrio species septicemia patient complains of ophthalmic symptoms, such as blurred vision or ocular pain. When clinicians diagnose endophthalmitis, make an effort to identify causative organisms. When bacterial infection is suspected, inject antibiotics intravitreously or vitrectomy must be done as faster as possible.

Study on the Healing and Correction of Rachitic Leg Deformity / 대한정형외과학회잡지

Eighty three rickets could be diagnosed at our department during eight years from August of 1969 to July of 1977. Among them fourteen children, whose radiographs and clinical description were precise with well-documented follow-up study of more than one year, were subjected to this analysis. Evaluation of the healing and correction of the lower leg deformity in these rachitic children obtained the following results. 1. Among fourteen rachitic children, thirteen patients (26 legs) showed varus and one patient (2 legs) showed valgus deformity. 2. Mean mechanical tibio-femoral angle showed shift from the initial 16.1°±5.3° to 5.5°+4.0° at final visit, which indicated the gradual correction of the deformity with the advance of the ages of children. The follow-up study after three years in this series showed that the correction became almost complete. 3. At the epiphyseo-metaphyseal region of the distal femur, the initial angle showed two distinct trends of change. The initial varus angle more than 7 or 8 showed the decrease at the later follow-up study, while the initial angle less than 7 or 8 showed the increase. 4. The epiphyseo-metaphyseal region of the proximal tibia showed the minimum change of angle. Mean angle of deviation from the vertical line was 3.7°±2.9° at first visit and 2.6°± 2.4°at final visit. The least degree of varus and the trend toward valgus observed in this region may refiect its compensatory activity against the varus deformity of the leg as a whole. 5. The epiphyseo-metaphyseal region of the distal tibia showed the maximum degree of varus at both initial and final check although the greatest degree of correction was attained. The initial mean varus angle of 23.9°±9.2° became 12.9°±7.1° at final visit. 6. The results of this study have shown that the correct evaluation of the rcchitic leg deformity is possible with measurement of the mechanical tibio-femoral angle and that the deviation angle of each epipyseo-metaphyseal region is preferable.
