Teratoma is one of germ cell tumor, common neoplasm in women of reproductive age, but it can arise at any age. Its malignant transformation is rare, less than 2%, frequently at older age. Nearly all the cases are squamous, sarcomatous and adenomatous transformation. Here we present a case of mixed transformation, adeno-squamous cell carcinoma with brief review of the concerned literature.

Actinomycosis is an oppoturnistic infection of actinomyces, which are relatively avirulent endogenous oral commensals. After trauma or infection, they breach the normally protective mucosal barriers to invade adjacent soft tissue structures. Lesions routinely contain other bacteria, the normal resident flora at the site of primary infection, which act synergistically with actinomyces species to provoke this unique infection, which range from an acute suppurative process to a chronic fibrotic process. According to epidemic studies about pelvic actinomycosis, it should be significantly related to IUD(intrauterine device). It is accounted that IUD cause chronic intrauterine infection, tissue injury and act as nucleus for parasitic infestation. Here we present a case of pelvic actinomycosis related to IUD with brief review of the concerned literature.

PURPOSE: Recently, several reports have documented persistent visual field changes associated with long-term use of Vigabatrin, an antiepileptic drug. Epilepsy is a common disease in children, therefore we investigated perimetric changes in children who were on Vigabatrin treatment. METHODS: Total 36 eyes of 18 patients who had been treated with Vigabatrin were tested with Humphrey Field Analyzer. The visual fields were assessed using central 30-2 threshold test and peripheral 60-4 threshold test. RESULTS: In central 30-2 threshold tests, 13 eyes(40.6%) showed mild visual field constrictions and 4 eyes(12.5%) showed severe visual field constrictions. In peripheral 60-4 threshold tests, 23 eyes(71.8%) showed visual field changes. CONCLUSIONS: Asymptomatic visual field loss may develop in Vigabatrin-treated children. Regular examinations of the visual field is warranted for Vigabatrin-teated children.

In Sprague Dawley (SD) rats, antibodies against strains of Orinentia tsutsugamushi, Kato, Karp and Gilliam, were produced in order to investigate their longevity and cross-reactivities to their corresponding homologous and heterologous antigens. By immunofluorescence assay (IFA) of IgG and IgM, it was shown that the immunity to the homologous strains persisted at a higher level (longevity of at least 34 weeks with higher IFA titers). On the other hand, the immunity to the heterologous strains persisted at a lower level (longevity of 10 to 34 weeks with lower IFA titers). Since infection with one strain of O. tsutsugamushi does not preclude reinfection with other strains, understanding of the antigenic diversity of O. tsutsugamushi and duration of the immunity to both homologous and heterologous strain is very important in diagnosis of scrub typhus.

Dermoid is a kind of choristoma and rare congenital benign tumor. It is ugly in appearance and especially dermoid appears at corneal limbus. The above 2 cases which we report invade cornea and it is especially giant compared with the report which has been reported untill now.

PURPOSE: To evaluate the influence of refractive blur on the results of mfERG. METHODS: mfERG was performed on 10 healthy volunteers with a refractive error within +/- 1 diopter. The central 30 degrees of the ocular fundus were stimulated by an array of 103 hexagonal elements, for four minutes, using VERISTM. To change the refractive status, 6-cm diameter corrective lens, of -6, -4, -2, plano, +2, +4, and +6 diopters, were placed in front of the eyes, and the examination distance adjusted to compensate retinal image size changes due to corrective lens. The mfERG responses were grouped by 6 concentric rings, and then averaged. For each ring, the latencies and amplitudes of the N1, P1 and N2 were analyzed. The 6 rings were divided into the central (ring 1, 2) and peripheral (ring 3~6) retina, and the latencies and amplitudes of the N1, P1 and N2 were then also analyzed. RESULTS: Refractive blur can affect the results of the mfERG. Latency delay was more common at the peripheral than central retina, but had no statistically significant correlations with the refractive power increase. CONCLUSIONS: When the viewing distance was adjusted to create a constant retinal image size, the influence of refractive blur may cause some changes in the mfERG results. Therefore, when evaluating the results of an mfERG, the effects of the refractive error should be borne in mind.

A 44-year-old woman who comlpained of dizziness and generalized weakness was admitted. The hemoglobin was 6.6g/dL, hematocrit 25.5%, and serum ferritin 2.14 ng/mL Stool occult blood was positive and microcytic hypochromic anemia was found on periyheral blood smear. Gastroscopic examination showed about 2 x 1 cm sized hemispherical sebmucosal tumor on antrum. The patient underwent operatioh for confirmatory diagnosis and treatment. The final pathologic diagnosis of the resected lesion was hemangioma of stomach. Cavernous hemangioma of stomach is a rare disease.Mostly, it has a benign course clinically, but early diagnosis is important because massive hemorrhage and anemia by chronic blood loss can occur. We report a case of hemangioma of stomach with review of literature.

PURPOSE: To report a case of ulnar neuropathy as an extraocular complication following retinal detachment surgery and face-down positioning. CASE SUMMARY: A 65-year-old woman was referred to our hospital with decreased visual acuity in the left eye. Fundus examination revealed a rhegmatogenous retinal detachment not involving the macula in the left eye. A vitrectomy with scleral encircling and 18% SF6 gas tamponade was performed. The patient was instructed to assume a face-down position. After 5 days, the patient reported having paresthesia and numbness of the left 4th and 5th fingers. Neurologic exams were performed and the results indicated ulnar neuropathy. There was no improvement in the neurologic symptoms during the 6-month follow-up. CONCLUSIONS: Surgeons performing retinal surgery should caution their patients of ulnar neuropathy when face-down positioning is required. The patients should be instructed to minimize the time spent with their elbows flexed in a stationary position. Additionally, the pressure loaded on the bent elbow should be minimized.
