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.

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.

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.

Leiomyosarcoma of the intestine is an uncommon malignant tumor of the small and large bowels. It may metastasize mostly to the peritoneum, omentum and liver. We describe a case of a liver metastasis from ileal leiomyosarcoma which was treated by right hepatic lobectomy. Ultrasonography revealed multiple cysts in both lobes of liver and pelvic mass. Computerized tomography of the abdomen revealed that lobulated, marginated, low density mass was noted in ileal loop, and multiple, well-defined, low density masses were identified in both lobes of the liver. The patient underwent exploratory laparotomy and removal of the ileal leiomyosarcoma. One month later, the patient underwent a right hepatic lobectomy and removal of a cystic mass on the liver dome of the left lobe. The patient recovered and was discharged by postoperative day 24.

PURPOSE: To evaluate the changes of electroretinographic responses according to the lens opacity type and severity in cataract patients with normal retina. METHODS: Retrospective study was performed on 79 eyes of 79 patients who had undergone electroretinograms (ERG) before cataract surgery. The patients with high myopia, diabetes mellitus, hypertension or glaucoma were excluded. Cataracts were classified using Lens Opacities Classification System III (LOCS III). Whether the ERG results are different according to the location and severity of lens opacity was analyzed. RESULTS: Marked reduction in amplitude and delay in implicit time were observed in mature cataracts. Amplitudes of a- and b-wave were reduced significantly, especially a-wave in maximal combined response and b-wave in rod response (P<0.01). Among the 4 groups, excluding the mature opacity, amplitude was reduced in posterior subcapsular opacity. Implicit times were also delayed, but not significant. CONCLUSIONS: Lens opacity, especially posterior subcapsular opacity affects the ERG results significantly. These findings should be considered in evaluating the retinal abnormalities in patients with cataract.

Retinitis pigmentosa without pigment is a varient of retinitis pigmentosa which is a hereditory disorder. It is characterized by decreased visual acuity, night blindness and contraction of visual field in both eyes. A 42-year old male patient was complained of decreased visual acuity and night blindness. And Pt was diagnosed as retinitis pigmentosa without pigment with clinical symptoms and signs, ophthalmoscopic findings, fluorescein angiography and electroretinogram. So authors report a case of retinitis pigmentosa without pigment and a brief reviews of literatures.
