A synophthalmia, another form of cyclopia, in which the element of the two eyes are partially fused to form an apparently single eye in the middle of the forehead. The synophthalmia is a result of complex, neural plate misdevelopment syndrome involving the eye, brain, skull and face. It is well known that synophthalmia is due to heterogenous causes, most of which chromosomal imbalances. We experienced a case of synophthalmia associated with proboscis, alobar holoprosencephaly and chromosomal anomaly 46, XX, -15,t (15 q, 21 q). Diagnosis was confirmed by brain MRI and autopsy, The patient died about 20 hours of age and autopsy was done. A brief review of the literatures was also presented.

A 38-year-old woman was presented with a dark brown plaque on the abdomen. Clinically, the tumor was simulating the appearance of dysplastic nevus. Microscopically, the cells of the stratum malphighii lay in a disordered pattern. Many cells in the epidermis were atypical and melanin pigment was mainly in the basal layer of the epidermis and the upper dermis. Diagnosis of pigmented Bowen's disease was made. Pigmented Bowen's disease is rarely found at body sites other than the anogenital area.

The unilateral megalencephaly is a rare brain malformation characterized by cerebral asymmetry and cortical dysplasia caused by faulty migration of the subependymal neuroblasts. We experienced a case of unilateral megalencephaly in a two day-old male with the chief complaint of asymmetric head appearance. Large left hemisphere with agyria, pachygyria, dilatation of lateral ventricle, and the thick cortex of the ipsilateral hemisphere were showed in brain MRL, Clinical findings in this case were intractable seizure, hemiparesis, and psychomotor retardation. A review of literatures was also presented briefly.

BACKGROUND: Organophosphate insecticides poisoning is one of the most common toxicologic emergencies in Korea. There have been few reports of organophosphate intoxication via parenteral route, although many reports on organophosphate intoxication by oral ingestion were present in the literature. This study aimed to validate the clinical characteristics of organophosphage intoxication according to the route of administration to the body. METHOD: Data were collected retrospectively by the review of the medical records from 49 patients with organophosphate intoxication. Severity of intoxication was classified by the Namba's Classification. Collected data were analysed and compared on the clinical features and laboratory findings between the patient intoxicated by inhalation or contact(parenteral group, n=23) and the other oral ingestion(enteral group, n=26). RESULTS: Severity class by clinical features was higher in enteral group than parenteral group. Severity class by serum cholinestetrase level was not positively correlated with severity class by clinical manifestations. Cholinesterase level tended to overestimate the severity of intoxication in parenteral group. Ventilator therapy and admission to intensive care unit were more frequently needed in enteral group than parenteral group in case that the severity class by clinical features was equal. CONCLUSION: In patients with organophosphate intoxication by parenteral route, serum cholinesterase level of the patient had disparity with clinical severity of intoxication. Considering this disparity, clinical severity should be considered as a more important indicator for treatment of organophosphate intoxication including atropinization, rather than serum cholinesterase level in patients intoxicated by parenteral route.

PURPOSE: To evaluate the levels of vascular endothelial growth factor (VEGF) in the vitreous of patients with proliferative diabetic retinopathy (PDR) and to find any correlation between clinical and fundus findings, grade of PDR, post-operative complications and surgical outcomes. METHODS: Using ELISA, the vitreous concentration of VEGF was measured in 74 patients with PDR who had undergone vitrectomy and in 13 control patients. RESULTS: The pre-operative levels of VEGFin the vitreous of the PDR patients was significantly increased compared with those of the control and with the post-operative levels. The pre-operative VEGF concentration in the vitreous of the PDR patients was correlated with the duration of diabetes and the severity of proteinuria, but not with the type of diabetes, level of HbA1c, hypertension and BUN/creatinine levels. The severity of PDR was also correlated with pre-operative VEGF levels, especially in NVD, NVE and NVI, but was not correlated with vitreous hemorrhage and fibrous proliferation elsewhere. There was negative correlation with the severity of retinal detachments. The vitreous levels of VEGF in PDR were significantly lower in those who had received previous laser photocoagulation than in those who did not. The VEGF levels were also significantly elevated in patients who developed NVI or NVG in the post-operative period. The changes of visual acuity after vitrectomy in the PDR patients were not correlated with vitreous levels of VEGF. CONCLUSIONS: These results show that VEGF is related to intraocular angiogenesis, progression of PDR and post-operative complications such as NVI or NVG, and that panretinal photocoagulation could prevent the progression of PDR.

This report is presented in which an asymptomatic parturient with Mobitz I second degree heart block developed high grade heart block during cesarean section under general anesthesia with enflurane. Progression of the block might be associated with vagal reflex. The event in this case suggests that the patients with pre-existing heart block may be a risk factor for development of high grade atrioventricular block during general anesthesia and surgery.

BACKGROUND/AIMS: Immune thrombocytopenic purpura (ITP) is an autoimmune disease that is mediated by anti-platelet antibodies. Based on the pathogenesis of ITP we evaluated the efficacy of intravenous anti-D immunoglobulin for adult chronic ITP. METHODS: Fourteen patients (4 without splenectomy and 10 with splenectomy) with refractory chronic ITP were treated with 50-70 microgram/kg of intravenous anti-D immunoglobulin only once. Treatment effects were evaluated by measuring the platelet counts and hemoglobin levels. RESULTS: Five patients (36%) showed a response; improvement in the platelet count lasted for on average 7 days (range: 2~24 days). There were no serious adverse effects. CONCLUSION: Anti-D immunoglobulin, which is associated with an Fc receptor blockade, appeared to be safe and effective for the treatment of adults with chronic ITP. Further studies are needed to confirm these findings and define further potentially effective treatment protocols with intravenous anti-D immunoglobulin.

OBJECTIVE: To evaluate the effects of electric cortical stimulation (ECS) and transcranial direct current stimulation (tDCS) on motor and cognitive function recovery and brain plasticity in focal traumatic brain injury (TBI) of rats model. METHODS: Forty rats were pre-trained to perform a single pellet reaching task (SPRT), rotarod test (RRT), and Y-maze test for 14 days, then a focal TBI was induced by a weight drop model on the motor cortex. All rats were randomly assigned to one of the three groups: anodal ECS (50 Hz and 194 μs) (ECS group), tDCS (0.1 mA, 50 Hz and 200 μs) (tDCS group), and no stimulation as a control group. Four-week stimulation, including rehabilitation, was started 3 days after the operation. SPRT, RRT, and Y-maze were measured from day 1 to day 28 after the TBI was induced. Histopathological and immunohistochemistry staining evaluations were performed at 4 weeks. RESULTS: SPRT was improved from day 7 to day 26 in ECS, and from day 8 to day 26 in tDCS compared to the control group (p < 0.05). SPRT of ECS group was significantly improved on days 3, 8, 9, and 17 compared to the tDCS group. Y-maze was improved from day 8 to day 16 in ECS, and on days 6, 12, and 16 in the tDCS group compared to the control group (p < 0.05). Y-maze of the ECS group was significantly improved on day 9 to day 15 compared to the tDCS group. The c-Fos protein expression was better in the ECS group and the tDCS group compared to the control group. CONCLUSION: Electric stimulation in rats modified with a focal TBI is effective for motor recovery and brain plasticity. ECS induced faster behavioral and cognitive improvements compared to tDCS during the recovery period of rats with a focal TBI.
