Abstract
PURPOSE To report cases that showed partition-like, dark areas in the cone mosaic on adaptive optics scanning laser ophthalmoscopy (AO-SLO) images in eyes with inner nuclear layer (INL) microcystic changes. METHODS Eyes with INL microcystic changes were imaged by prototype AO-SLO. RESULTS An eye with Leber hereditary optic neuropathy, an eye with traumatic optic neuropathy, and an eye with retinitis pigmentosa that showed microcystic lesions in the INL were imaged by AO-SLO. The images revealed characteristic, dark, partition-like lesions in the cone mosaic of all the eyes in areas where microcystic changes in the INL were shown by spectral domain optical coherence tomography. The AO-SLO findings in eyes with optic neuropathy were quite similar in shape and size to those seen in eyes with retinitis pigmentosa. CONCLUSION We report cases that manifest dark, partition-like areas in the cone mosaic on AO-SLO images. Microcystic lesions in the INL may affect the images of the cone mosaic.

Abstract
PURPOSE To investigate photoreceptor changes in eyes with glaucoma. DESIGN Cross-sectional study. METHODS The study included 35 eyes of 35 patients with primary open-angle glaucoma who had suffered parafoveal visual field loss at least 3 years previously, as well as 21 eyes of 21 normal subjects. Eyes with an axial length ≥26.0 mm were excluded. All subjects underwent a full ophthalmologic examination, including spectral-domain optical coherence tomography (SDOCT) and prototype adaptive-optics scanning laser ophthalmoscopy (AO-SLO) imaging. RESULTS As determined using AO-SLO, eyes with glaucoma did not differ significantly from normal eyes in terms of either cone density (26 468 ± 3392 cones/m2 vs 26 147 ± 2700 cones/m2, respectively; P = .77; measured 0.5 mm from the foveal center) or cone spatial organization (ratio of hexagonal Voronoi domain: 43.7% ± 4.4% vs 44.3% ± 4.9%; P = .76; measured 0.5 mm from the foveal center). Furthermore, SDOCT showed that the 2 groups did not differ significantly in terms of the photoreceptor-related layer thickness, and that the photoreceptor ellipsoid zone band was continuous in all normal and glaucoma eyes. In glaucoma eyes with vertically asymmetric severity, the more affected side did not significantly differ from the less affected side in terms of cone density, cone spatial organization, or photoreceptor-related layer thickness. In 8 eyes (22.9%) with glaucoma, dark, partition-like areas surrounded the cones on the AO-SLO. CONCLUSIONS Both AO-SLO and SDOCT showed cone integrity in eyes with glaucoma, even in areas with visual field and nerve fiber loss. In AO-SLO, microcystic lesions in the inner nuclear layer may influence images of the cone mosaic.

Abstract
PURPOSE To investigate the efficacy of targeted exome sequencing for mutational screening of Japanese patients with cone dystrophy (CD) or cone-rod dystrophy (CRD). METHODS DNA samples from 43 Japanese patients with CD or CRD were sequenced using an exome-sequencing panel targeting all 193 known inherited eye disease genes and next-generation sequencing methodologies. Subsequently, candidate variants were screened using systematic data analyses, and their potential pathogenicity was assessed using distinct filtering approaches, which included the frequency of the variants in normal populations, in silico prediction tools, and cosegregation. RESULTS Causative mutations were detected in 12 patients with CD or CRD (27.9%). In total, 14 distinct mutations were identified in the genes ABCA4, CDHR1, CRB1, CRX, GUCY2D, KCNV2, PROM1, PRPH2, and RDH5, including four novel mutations, c.3050+1G>A in ABCA4, c.386A>G in CDHR1, c.652+1_652+4del in CRB1, and c.454G>A in KCNV2. Moreover, a putative pathogenic mutation was identified in RGS9BP, a gene recognized as the source of bradyopsia. CONCLUSIONS Targeted exome sequencing effectively identified causative mutations in Japanese patients with CD or CRD. The results confirmed the heterogeneity of the genes responsible for CD and CRD in Japanese populations, as well as the efficacy of targeted exome sequencing-based screening of patients with inherited retinal degeneration.

Abstract
Objectives To compare the optic nerve head (ONH) structure between compressive optic neuropathy (CON) and glaucomatous optic neuropathy (GON), and to determine whether selected ONH quantitative parameters effectively discriminate between GON and CON, especially CON cases presenting with a glaucoma-like disc. Methods We prospectively assessed 34 patients with CON, 34 age-matched patients with moderate or severe GON, and 34 age-matched healthy control subjects. The quantitative parameters of ONH structure were compared using the Heidelberg Retina Tomograph 2 (HRT2) and Spectralis optical coherence tomography with an enhanced depth imaging method. Results The mean and maximum cup depths of CON were significantly smaller than those with GON (P<0.001 and P<0.001, respectively). The distance between Bruch's membrane opening and anterior surface of the lamina cribrosa (BMO-anterior LC) of CON was also significantly smaller than that of glaucoma but was similar to that of the healthy group (P<0.001 and P = 0.47, respectively). Based on Moorfields regression analysis of the glaucoma classification of HRT2, 15 eyes with CON were classified with a glaucoma-like disc. The cup/disc area ratio did not differ between cases of CON with a glaucoma-like disc and cases of GON (P = 0.16), but the BMO-anterior LC and mean and maximum cup depths of CON cases with a glaucoma-like disc were smaller than those in GON (P = 0.005, P = 0.003, and P = 0.001, respectively). Conclusions Measurements of the cup depths and the LC depth had good ability to differentiate between CON with a glaucoma-like disc and glaucoma. There was no laminar remodeling detected by laminar surface position in the patients with CON compared to those with GON.

Abstract
Purpose To investigate the association between visual changes and retinal vessel attenuation in patients with retinitis pigmentosa (RP). Design A retrospective, longitudinal, observational cohort study. Methods We analyzed 45 eyes from 45 subjects who were followed-up for ≥3 years at our clinic. Using the computer-based Interactive Vessel Analysis program, central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE) were determined. Age- and sex-matched controls from normal subjects were selected from our archived fundus photograph library. Visual acuity, visual field area (Goldmann perimetry, V4e white test light), mean deviation (Humphrey perimetry, central 10-2 program), and central macular thickness (optical coherence tomography) were analyzed for correlations with CRAE and CRVE. Results Both CRAE and CRVE were significantly decreased in RP eyes (94.9±13.5 μm and 155.6±20.0 μm, respectively) compared with control eyes (138.1±14.7 μm and 215.0±20.4 μm, respectively, both P<0.001). After 3 years of follow-up, visual field area was associated with both CRAE (r=0.584, P<0.01) and CRVE (r=0.500, P=0.008). A significant association was also observed between mean deviation and CRAE (r=0.298, P=0.047). In eyes with RP, a narrower vessel caliber at baseline was associated with a larger decline in visual acuity over the 3-year follow-up interval (CRAE: r=−0.344, P=0.021; CRVE: r=−0.314, P=0.035). Conclusion Retinal vessel caliber is associated with some visual functions in patients with RP.

Abstract
PURPOSE To assess macular photoreceptor abnormalities in eyes with resolved branch retinal vein occlusion (BRVO) using adaptive optics scanning laser ophthalmoscopy (AO-SLO). DESIGN Prospective observational cross-sectional case series. METHODS After complete resolution of macular edema and retinal hemorrhage, 21 eyes (21 patients) with BRVO underwent full ophthalmologic examination and imaging with optical coherence tomography (OCT) and a prototype AO-SLO system. Cone density and spatial mosaic organization were assessed using AO-SLO images. RESULTS Regular parafoveal cone mosaic patterns were clearly visualized with the prototype AO-SLO imaging system in the BRVO-unaffected side. However, in the side of the retina previously affected by the BRVO, cone mosaic patterns were disorganized and dark regions missing wave-guiding cones were apparent. Additionally, retinal capillaries were dilated, no longer had a uniform caliber, and had less direct paths through the retina. In the affected side, parafoveal cone density was significantly decreased, compared with the corresponding retinal area on the unaffected side (P < .001). Furthermore, the hexagonal Voronoi domain ratio and the nearest-neighbor distances were significantly lower than in the unaffected side (P < .05). These parameters were also correlated with photoreceptor layer integrity in the parafovea. CONCLUSIONS After BRVO-associated retinal hemorrhage and macular edema resolved, affected parafoveal cone density decreases and the cone mosaic spatial arrangement is disrupted, becoming more irregular. These cone microstructural abnormalities may extend to parafovea in the BRVO-unaffected side.

Abstract
PURPOSE To assess macular photoreceptor abnormalities in eyes with fundus albipunctatus with RDH5 mutation by using adaptive optics scanning laser ophthalmoscopy (AO-SLO). DESIGN Prospective cross-sectional study. METHODS Ten eyes with fundus albipunctatus and 11 normal eyes underwent a full ophthalmologic examination, microperimetry, spectral-domain optical coherence tomography (SD OCT), and imaging with a prototype AO-SLO system. Cone density and spatial organization of the cone mosaic were assessed using AO-SLO images. Statistical analysis was done using data from right eyes of all patients. RESULTS Four patients had the same mutation in RDH5 (c.928delC/insGAAG), and 1 patient had a novel mutation in RDH5 (c.718delG). AO-SLO revealed the presence of small patchy dark areas representing cone loss in the macula of all eyes with fundus albipunctatus, including eyes for which fundus photographs showed no macular abnormalities and SD OCT did not reveal any visible defects in the photoreceptor layer. Compared to normal eyes, eyes with fundus albipunctatus demonstrated significantly lower cone density in areas at 0.5 mm from the center of the fovea (P = .020). At 0.5 mm and 1.0 mm from the center of the fovea, eyes with fundus albipunctatus showed fewer cones with 6 neighbors (P = .041 and P = .006). AO-SLO revealed hyperreflective mosaics surrounded by hyporeflective rings in areas corresponding to the retinal flecks. CONCLUSIONS Macular cone density is lower and the regularity of the macular cone mosaic spatial arrangement is disrupted in eyes with fundus albipunctatus. AO-SLO imaging is a sensitive quantitative tool for detecting photoreceptor abnormalities in eyes with fundus albipunctatus.

Abstract
PURPOSE To report the clinical and immunological characterization of paraneoplastic retinopathy (PR) and to investigate the association between spectral-domain optical coherence tomography (SDOCT) findings and the targets of autoantibodies in PR. METHODS We retrospectively enrolled eight patients (age range, 57-85 years; four men and four women) suspected of having PR. All patients underwent comprehensive ophthalmic examinations, including best-corrected visual acuity (BCVA) measurement, slitlamp examinations, kinetic visual field testing with Goldmann perimetry, electroretinography (ERG), fundus photography, fluorescein angiography, fundus autofluorescence (FAF), SDOCT, and serum sample tests (Western blot analysis and immunohistochemistry [IHC]). RESULTS Three patients had a history of malignant tumors, and four patients were newly diagnosed as having neoplastic tumors (small cell lung carcinoma [SCLC], thymoma, pancreatic neuroendocrine neoplasm, and colon cancer). Another de novo malignancy (SCLC) was detected in a patient with a history of malignancy (bladder cancer and liposarcoma). The BCVA in these patients ranged from hand motion to 1.5. Goldmann perimetry revealed island, ring-shaped, concentric, or central scotoma. All patients showed nonrecordable or reduced amplitude results on ERG. Fluorescein leakage was detected in five patients. Hyperautofluorescence and/or hypoautofluorescence on FAF was detected in six patients. The serum sample tests identified anti-retinal antibodies in all patients. Patients whose serum contained anti-photoreceptor or anti-retinal pigment epithelium antibody on IHC showed damage of the outer retina on SDOCT. CONCLUSIONS In this case series, PR was associated with a variety of neoplasms and autoantibodies. Spectral-domain OCT can be used to characterize morphologic changes, and the changes were associated with the targets of autoantibodies.

Abstract
PURPOSE To investigate longitudinal changes in peripapillary retinal nerve fiber layer (RNFL) thickness in patients with retinitis pigmentosa (RP). METHODS We re-examined 103 RP patients whose RNFL thickness was previously examined and reported. RNFL thickness was measured using Stratus optical coherence tomography and was compared with the previous measurements. The results were also compared with that of previously reported normal subjects. Association between the decrease rate and visual acuity, and visual field was also investigated. RESULTS The mean follow-up period was 56.9 months. After excluding the patients in whom RNFL images were of poor quality, 88 patients were eventually analyzed. The average RNFL thickness decreased from 105.8 to 98.2 μm during the period, with the average rate of decrease being 1.6 μm/year. The decrease in RNFL was more evident in superior and inferior sectors. Cross-sectional linear regression analysis also revealed an age-dependent decrease in RNFL, with the slower rate of decrease being 0.94 μm/year. The decrease in RNFL thickness was significantly faster than that reported in normal subjects. The decrease rate was not associated with visual functions. CONCLUSION Age-dependent RNFL thinning occurs at a faster rate in RP patients as compared with that in normal subjects. The result supports the notion that pathologic changes involve inner retina as well as outer retina in eyes with RP. Considering the discrepancy in the rate of RNFL thinning estimated from trend analysis and longitudinal measurement, care should be taken when interpreting the result of cross-sectional analysis.

SUBJECTS AND METHODS DNA extracted from the blood samples of 84 families (87 patients) with retinal dystrophies (retinitis pigmentosa, Leber congenital amaurosis, cone-rod dystrophy and Bietti's crystalline retinopathy) was screened by Asper Biotech services. All the variants detected by microarray analysis were verified by direct sequencing. RESULTS Mutations were detected in 2 of 36 families with autosomal dominant retinitis pigmentosa, 2 of 4 with Leber congenital amaurosis, 11 of 24 with cone-rod dystrophy, 3 of 7 with macular dystrophy and 6 of 7 with Bietti's crystalline retinopathy. CONCLUSION Genotype screening using microarray analysis can be effectively used to determine the variants of retinal dystrophies, except retinitis pigmentosa, in the Japanese population.

Abstract
PURPOSE To assess macular photoreceptor abnormalities in eyes with retinitis pigmentosa (RP) with preserved central vision using adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS Fourteen eyes of 14 patients with RP (best-corrected visual acuity 20/20 or better) and 12 eyes of 12 volunteers underwent a full ophthalmologic examination, fundus autofluorescence, spectral-domain optical coherence tomography (SD-OCT), and imaging with a prototype AO-SLO system. Cone density and spatial organization of the cone mosaic were assessed using AO-SLO images. RESULTS In 3 eyes with RP and preserved central vision, cones formed a mostly regular mosaic pattern with small patchy dark areas, and in 10 eyes, the cone mosaic patterns were less regular, and large dark regions with missing cones were apparent. Only one eye with RP demonstrated a normal, regular cone mosaic pattern. In eyes with RP, cone density was significantly lower at 0.5 mm and 1.0 mm from the center of the fovea compared to normal eyes (P<0.001 and 0.021, respectively). At 0.5 mm and 1.0 mm from the center of the fovea, a decreased number of cones had 6 neighbors in eyes with RP (P = 0.002 for both). Greater decrease in cone density was related to disruption of the photoreceptor inner segment (IS) ellipsoid band on SD-OCT images (P = 0.044); however, dark regions were seen on AO-SLO even in areas of continuous IS ellipsoid on SD-OCT. Decreased cone density correlated thinner outer nuclear layer (P = 0.029) and thinner inner segment and outer segment thickness (P = 0.011) on SD-OCT. CONCLUSIONS Cone density is decreased and the regularity of the cone mosaic spatial arrangement is disrupted in eyes with RP, even when visual acuity and foveal sensitivity are good. AO-SLO imaging is a sensitive quantitative tool for detecting photoreceptor abnormalities in eyes with RP.

Abstract
Neuroinflammation involving CC chemokines such as monocyte chemoattractant protein-1 (MCP-1) has been demonstrated in the pathological process of retinitis pigmentosa (RP), an inherited degenerative retinal disease. However, the mechanism of MCP-1 and its receptor CCR2 involvement in the disease remains unclear. To investigate the role of MCP1/CCR2 in RP pathogenesis, ccr2 mutant RP mice (ccr2(-/-) rd10) were created and analyzed. The expression of MCP-1, RANTES, stromal cell-derived factor (SDF-1), and tumor necrosis factor-α (TNF-α) in the retinas of wild-type, rd10, and ccr2(-/-) rd10 mice was analyzed using quantitative RT-PCR. Photoreceptor apoptosis (TUNEL staining) and the number of microglia (positive for the F4/80 antibody) in the retina were examined. Retinal function was assessed using electroretinograms, and the structure of the whole retina was analyzed from images obtained using optical coherence tomography (OCT) and by histological examination. The expression levels of MCP-1, RANTES, and SDF-1 increased with time in the rd10 mice but not in the wild-type mice. Rearing the mice in the dark prevented degeneration and resulted in thicker photoreceptor layers at each time point. In those mice, the peaks of chemokine expression shifted to a later time with degeneration, suggesting that the expression of these chemokines was induced during the progression of degeneration. Although the difference was not so obvious, the retina in the ccr2(-/-) rd10 mice was consistently and significantly thicker than that in the rd10 (ccr2(+/+) rd10) mice at all time points. Rhodopsin gene expression was also higher in the ccr2(-/-) rd10 mice than in rd10 (ccr2(+/+) rd10) mice, suggesting photoreceptor survival in the former. Retinal function was also better preserved in the ccr2(-/-) rd10 mice than in the rd10 mice. The number of microglia in the retinas of the ccr2(-/-) rd10 mice was significantly lower than that in the retinas of the rd10 mice. Interestingly, the MCP-1 induction that was observed in the retinas of the rd10 mice was diminished in the retinas of the ccr2(-/-) rd10 mice. Our results suggest that the MCP-1/CCR2 system plays a role in retinal degeneration in rd mouse retinas. Retinal MCP-1 expression in the rd mouse retina may be partially controlled by ccr2-positive circulating cells.

Abstract
A patient with retinitis pigmentosa showed visual disturbances following successful cataract surgery. He had a dense asteroid hyalosis in the eye before cataract surgery. After the surgery he noticed that his vision became worse. The visual disturbance was explained as being caused by the progression of retinal degeneration. Although the electroretinogram was non-recordable, the degeneration of macular area appeared relatively small. We considered that dense asteroid hyalosis was responsible for his visual disturbances, and pars plana vitrectomy (PPV) was performed to remove the asteroid hyalosis. After the PPV, rapid improvement of his visual acuity was observed. Cataract surgery may affect the status of asteroid hyalosis and cause rapid visual loss. PPV should be considered for retinitis pigmentosa patients with dense asteroid hyalosis, especially when a large decrease in visual acuity is noted shortly after cataract surgery.

Abstract
The study tested the hypothesis that left atrial appendage (LAA) dysfunction in nonvalvular atrial fibrillation (NVAF) correlates with a prothrombotic state, and investigated whether the plasma natriuretic peptides are marker of LAA dysfunction in NVAF. Sixty-seven patients underwent transthoracic and transesophageal echocardiography. The left ventricular fractional shortening, left atrial diameter (LAD), LAA flow velocity and the grade of spontaneous echo contrast (SEC) were determined. The plasma concentrations of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), D-dimer, and thrombin-antithrombin III complex (TAT) were measured. The patients were divided into 2 groups according to LAA flow velocity: group I (LAA velocity <20 cm/s) and group II (LAA velocity > or = 20cm/s). The SEC score, D-dimer, TAT, BNP and LAD were significantly increased in group I. Based on simple linear regression analysis, SEC score (r=-0.638), LAD (r=-0.493), D-dimer (r = -0.485), BNP (r = -0.463), TAT (r = -0.455) and age (r = -0.314) were inversely correlated with LAA flow velocity. Multivariate analysis showed that SEC score (p = 0.0014) and plasma BNP level (p=0.0075) were independent negative predictors for LAA flow velocity. In conclusion, LAA dysfunction is associated with a prothrombotic state, and the plasma BNP concentration may serve as a determinant of LAA function in NVAF.

Abstract
The criteria for assessing adult brain death have been already established, but those for infant brain death have not been yet established in Japan. We report auditory brainstem response (ABR) and postmortem pathology of the temporal bone and brain of a brain-dead 9-month-old female. During the comatose state, her ABR showed only waves I and II bilaterally. Autopsy revealed the presence of a left cerebellar astrocytoma, herniation and anoxic encephalopathy. The pathological examination of the temporal bone revealed the destruction of the inner ear particularly on the left side. In the auditory pathway of brain-dead patients, degeneration occurs first in the cerebrum, followed by the cochlear nerve. Thus, ABR is one of the useful means to assess brain death even in infants.

Abstract
Proliferation of vascular smooth muscle cells (VSMC) is crucial to the progression of arteriosclerosis. In this study, we examined the role that interactions among endothelin-1 (ET-1), CD44, and hyaluronic acid (HA) play in VSMC proliferation. Co-localization of ET-1, CD44 and HA positive areas, as well as proliferating cell nuclear antigen positive nuclei, were observed in mouse neointima induced by endothelial injury. As found in intimal VSMC, cultured mouse VSMC secreted ET-1. The endothelin-converting enzyme (ECE) inhibitor, phosphoramidon, and endothelin type-A (ETA) receptor antagonist BQ-123 reduced expression of CD44 in VSMC. ET-1 reversed the reduction of CD44 expression by phosphoramidon. Because CD44 is a receptor for HA, we investigated the effects of phosphoramidon, BQ-123 or ET-1 on the mitogenic activity of HA in VSMC. Among the different molecular weights of this polysaccharide, oligosaccharides of HA (oHA) stimulated VSMC proliferation most effectively. Phosphoramidon and BQ-123 inhibited this oHA-induced DNA synthesis in VSMC. ET-1 reversed the suppression of oHA-induced proliferation by phosphoramidon. In conclusion, endogenously secreted ET-1 enhances oHA-stimulated VSMC growth via the ETA receptor in an autocrine manner. Thus it is suggested that the CD44-inducing activity of ET-1 is responsible for its stimulating effect on oHA-dependent growth of VSMC. These findings support the hypothesis that the interactions among ET-1, CD44 and HA promote the progression of arteriosclerosis.

Abstract
To understand the physiological roles of vasoactive intestinal contractor (VIC) and endothelin-2 (ET-2) in the uterus, we examined the expression levels of VIC mRNA by real-time quantitative reverse transcription-linked polymerase chain reaction (RT-PCR) and characterized the cellular distribution of VIC peptide and mRNA by immunostaining and in situ hybridization in mouse uterus. In pregnant mouse uterus, VIC mRNA expression changed considerably between Days 10.5 and 12.5 of pregnancy. The expression levels were significantly (p<0.05) higher (approximately fivefold) in the later stage of pregnancy (Days 12.5-17.5) than in the earlier stage (Days 7.5-10.5). In nonpregnant uterus, VIC mRNA expression was significantly (p <0.05) higher (approximately threefold) in proestrus and estrus than in diestrus. Immunohistochemical studies demonstrated the presence of VIC peptide in endometrial epithelial cells, myometrial cells, and vascular smooth muscle cells during the estrous cycle and pregnancy and after parturition. Notably, myometrial cells showed dominant immunostaining in proestrus and estrus, in the later pregnancy stage, and in the early postpartum period, analogous to the expression pattern of VIC mRNA. In situ hybridization confirmed localization of VIC mRNA in myometrial cells. These findings suggest that VIC may play an important role in the function of myometrial cells.

Abstract
A 62-year-old woman had been treated with propylthiouracil(PTU) for hyperthyroidism. Because bloody sputum, dyspnea, and severe hypoxemia developed, the patient was admitted to our hospital. Chest X-ray and chest computed tomographic (CT) films disclosed diffuse infiltrative shadows in both lung fields. Bronchoalveolar lavage revealed abundant hemosiderin-laden macrophages. Alveolar hemorrhage associated with myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) positive vasculitis syndrome was diagnosed because of the high serum level of MPO-ANCA. After the initiation of steroid therapy and termination of PTU, the infiltrative shadows in both lung fields disappeared, PaO2 improved, and MPO-ANCA decreased. There have been some reports of MPO-ANCA positive vasculitis syndrome developing during PTU therapy, but most were concerned with renal disease. We concluded that PTU and similar agents should be given consideration as one of the possible causes of MPO-ANCA-induced alveolar hemorrhage.

Abstract
Mice with the Otx2+/- mutation often die during the postneonatal period. Before death these animals, generated from TT2 ES cells and crossed with CBA mice, develop a dome-shaped head, weakness of the limbs, kyphosis, lethargy, drowsiness, and emaciation. Autopsy of these mice revealed eminent dilatation of lateral ventricles and a ballooned cerebrum. Histological analysis shows edematous change of the periventricular white matter. These results suggest that Otx2 functions as a head organizer, and a mutation of this gene is a likely cause of hydrocephalus in mammals. Additionally, craniobasal skeletal anomaly in half of the heterozygotes and dwarfism in some of the female heterozygotes are described.

Abstract
A case of suprasellar germ-cell tumor in a 9-year-old girl who later developed ovarian dysgerminoma is reported. The clinical course of the case is described and a double-primary tumor, rather than metastasis from either tumor to the other, is suggested by the authors to explain the oncogenesis in this patient. The authors strongly encourage that patients with intracranial germinoma be examined for associated extraneural lesions before, as well as after, the completion of the initial therapy.

Abstract
We reported a case of unilateral gustatory disturbance produced by a lesion in the contralateral midbrain. A 37-year-old man first noticed dysesthesia in the left side of his face. Later, the patient developed dysesthesia of the left part of the lip, muscular weakness on the left lower extremity and gustatory disturbance on the left side. MR scan disclosed a lesion in the tegmentum of the right midbrain, which showed low intensity on a T1-weighted image and high intensity on a T2-weighted image. This lesion could be due to multiple sclerosis. This case suggests that the unilateral gustatory information ascends via the contralateral pathway at the midbrain level. It is suggested that the central gustatory pathways above the ipsilateral pontine taste are ascend via the contralateral projections to the thalamic taste area (parvicellular portion of the ventral posteromedial thalamic nucleus, VPMpc).

Abstract
We performed magnetic resonance angiography (MRA) in 12 children with a suspected or angiographically proven moyamoya disease. MRA was performed by the three-dimensional, time-of-flight technique and, successfully depicted the primary abnormalities in the distal carotid arteries in 10 out of the 12 patients. In the other two patients, poor visualization of the intracranial vasculature strongly suggested the presence of the disease. On MRA, moyamoya vessels were visible in eight patients. The presence of anastomoses was also confirmed by MRA in seven of the 10 patients who had undergone encephalo-duro-arterio-synangiosis. Our findings suggest that MRA may be the tool of choice for selecting patients to undergo conventional angiography. However, establishing a definite diagnosis still requires some improvements in the delineation of the fine vasculature.

Abstract
A case of primary ocular and central nervous system malignant lymphoma was reported which was first manifested as bilateral uveitis ten months before the neurological symptoms appeared. The lesion of lymphoma in the central nervous system was clearly demonstrated as a heavy accumulation of N-isopropyl-123I-p-iodoamphetamine by single photon emission computed tomography. Since most brain tumors reportedly show a low uptake of N-isopropyl-123I-p-iodoamphetamine, single photon emission computed tomography with N-isopropyl-123I-p-iodoamphetamine could be helpful in making the diagnosis, as well as in visualizing primary central nervous system malignant lymphoma.

Abstract
The changes in cytochrome oxidase (CYO) activity in the primary somatosensory cortex (SI) induced by unilateral lesions restricted to the posterior ventrobasal region of the thalamus were investigated by histochemical techniques and photometric semi-quantitation in the rat. The CYO activity decreased rapidly and dramatically in layer IV of the lesioned side, reaching its lowest level within 2 weeks, and remained depressed at 8 weeks post-lesion. Segmentations normally seen in layer IV corresponding to barrels remained absent. While less marked decreases were also noted in other layers, obvious recovery was subsequently observed, attaining levels comparable to those on the intact size at 6 or 8 weeks post-lesion. The persistent decrease in layer IV appears to reflect a reduced thalamocortical activation of the dendritic profiles and neuronal perikarya. The recovery in other layers may represent an increase in the resting level of the initially depressed neuronal activity near to the original levels. The persistent reduction of function in the inhibitory surround, which is normally activated by thalamocortical input, may contribute to the increase in CYO activity.

Abstract
We report a case of five aneurysms, including three giant aneurysms, a pair of symmetric aneurysms, and two fusiform aneurysms. The initial clinical symptom was a cerebral ischemic attack. On admission, the patient complained of sudden onset of speech disturbance. Physical examination showed left hemiparesis. Radiological studies, including computed tomography and cerebral arteriography, revealed multiple low density areas bilaterally in the basal ganglia and three fusiform giant aneurysms bilaterally in the middle cerebral arteries and basilar artery. Considering the difficulty of surgical treatment, the patient was discharged. Six months later, complaining of right hemiparesis and total dysphasia, the patient was readmitted to our department. CT scan on admission revealed no changes except for ischemic changes. During the second admission, another attack of subarachnoidal hemorrhage due to rupture of the left middle cerebral artery aneurysm occurred, and the patient died. Autopsy was performed, and two more aneurysms, not visualized in the former studies, were found in the right anterior communicating artery and the cortical branch of the right middle cerebral artery. The occurrence of aneurysms in such a fashion as seen in the present case is to be very rare in the aspect of the size, the multiplicity and the bilaterally development.

Abstract
Scanning electron microscopic observation of the transtympanic infusion of 10% xylocain revealed twisting and disorders of outer hairs especially from the 2nd and 3rd rows of the basal to the 2nd turn of the organ of Corti, and adhesion and fusion of the sensory hairs of the crista ampullaris and otolith organ 1 and 4 days after injection. Four percent xylocain however demonstrated very minor alteration of the sensory hairs and no missing sensory hairs were detected from any cases. The authors hypothesized from electron microscopic observation that adhesion and fusion of vestibular sensory hairs or twisting and disorders of the sensory hairs of the organ of Corti might act to intercept harmful circulation of exclusion of abnormal excitement of hair cells and the innovation of electrical discharge of sensory hairs due not only to the pharmacological effects of xylocain but also to osmotic pressure.

Abstract
A neuro-otological examination was given to 22 patients with paroxysmal positional vertigo within 1 week of head injury. In all cases, reverse rotatory positional nystagmus accompanied by a vertiginous sensation was observed in the positional nystagmus test. No relationship between the affected side and the direction of eye movement in the head-hanging position was found in the positional nystagmus test. From the prognosis and the nystagmus findings, the cause of the vertigo was thought to be partial damage to the inner ear. The clinical course was generally favorable, but recovery was slower in the 11 cases with neuro-otologically demonstrated central nervous system disorders than in the other 11 cases.
