Relationship Between Visual Acuity and Foveation Window in Infantile Nystagmus by Analyzing Nystagmus Waveforms

PURPOSE: To report herein on Nystagmus Acuity Estimator Function (NAEF) based on the foveation time, obtained by analyzing waveforms of infantile nystagmus patients and comparing the results with the patients' actual visual acuity. METHODS: Electro-oculographic data of 27 patients with infantile nystagmus were reviewed. Data of patients only with jerk type nystagmus and reliable visual acuity were analyzed. The foveation time was measured, and NAEF was calculated and compared with the patients' actual best corrected visual acuity. RESULTS: A correlation analysis of the patients' best corrected visual acuity with NAEF was performed, and the retrieved coefficient was 0.4266. The p-value calculated using the Pearson correlation coefficient was 0.0282, implying that high NAEF correlates positively with visual acuity. CONCLUSIONS: Estimated visual acuity, calculated based on the waveforms, positively correlates with the patients' actual visual acuity with statistical significance. However, since the foveation time can be measured only in the patients with jerk-type nystagmus waveforms, further study should be performed on the measurement of the foveation time with other waveforms. Furthermore, the present study shows that such analysis is possible with electrooculogram settings in most general hospitals.

Nail - Patella Syndrome / 대한피부과학회지

The nail-patella syndrome is a genetically determined autosomal dominant disease with variabIe expression affectiag tissues of both ectodermal and mesodermal origin. The condition in an individual is characterized chiefly by dysplasia of the fingernails, hypoplastic or absent patellae, deformities or luxation af the head of the radius, and the presence of illiac horns. It is now well established that the locus for the nail-patella syndrome and the locus for the ABO blood groups are closely linked. We report 2 cases of nail-patella syndrome affected a brother and a sister in a family. Our 2 cases, with blood group B, showed dystrophic nails and hypoplastir. patellae.

Two Cases of Multicentric pigmented Bowen's Disease / 대한피부과학회지

Multicentric pigmented Bowen's diseas. (MPBD) is a bowenoid atypia in the genitalia of young adults which was first described by Lloyd in 1970. Clinically the lesions appear to be benign warts, but histologically they show bowenoid atypia., Although the pathogenesis and cours of MPBD is as yet unknown, many authors have suggested viral etiology. We recentiy encountered two cases of MPBD, one a 25 year-old male and the other a 38 year-old female, confirmed clinicallr and histopathologically. Case 1 showed spontaneous regression without any treatment, but case 2 showed recurrence of the lesions inspite of three times of surgical excision. The recurrent MPBD which has proven to be resistant to surgical therapy is unusual according to the previous reported cases.

Inflammatory Linear Verrucous Epidermal Nevus / 대한피부과학회지

We report a case of inflammatory linear verrucous epidermal nevus which was treated with an aromatic analog of vitamin A acid, Ro 10-9359, with significant effect, The patient is a 17-year-old woman who has had linear verrucous patches involving the entire length of the extensor surface of the right arm, right scapular area and anterior upper part of the right chest with persistent itching sensation of 10 years' duration. The patient was treated with oral Ro 10-9359 75mg daily, and showed marked improvement of the skin lesions after seven days of treatment, but the patient was lost to follow up.

Eoxinophilic FAsciitis: Report of a case / 대한피부과학회지

Eosinophilic fasciitis is a syndrome which is characterized by scleroderma-like skin involvement, eosinophilia and hypergammaglobulinemia without significant systemic changes. The primary pathological alterations are thickening and inflammation of the deep fascia. The majority of the cases that have been reportecd respond to systemic corticosteroids. We describe a 19-year-old male patient with eosinophilic fasciitis. On physical examination, he showed tender, edematous, indurated and tight skin in the back and both lower legs, and the laboratory findings showed eosinophilia and mild hypergammaglobulinemia. He also had Raynaud phenomenon, mild dyspnea, abdominal pain, pulmonary function abnormalities and roentgenographic evidence of pulmonary fibrosis. Result of a biopsy showed sclerosis of dermia and intense infiltrations of eosinophils, lymphocytes and histiocytes and fibroais of panniculus and fascia. Treatment with systemic corticosteroids showed complete resolution of the skin lesions, but after withdrawal new scleroderma-like skin lesions developed in the dorsum of feet.
