Abstract
We describe the multimodal management of a patient with proliferative diabetic retinopathy and diabetic macular edema associated with active acromegaly. A 61-year-old Japanese female who had had type 2 diabetic mellitus for > 10 years complained of deteriorated eyesight. She had distinct acromegalic features, and her visual acuity was 0.05 (right) and 0.4 (left) because of sub-capsular cataracts and proliferative diabetic retinopathy with macular edema. Anti-vascular endothelial growth factor treatments, cataract surgeries and retinal direct laser photocoagulation were performed together with gradual glycemic control with basal insulin to prevent worsening of the visual impairment. She was given an injection of a long-acting somatostatin analog (octreotide LAR) and began taking three bolus mealtime insulin shots with basal insulin beginning 1 month before undergoing a trans-sphenoidal adenomectomy. After this successful surgery, her blood glucose levels immediately decreased, and the rapid-acting insulin at mealtimes was discontinued with the observation of normal growth hormone and insulin-like growth factor (IGF)-1 levels, suggesting that her acromegaly was in remission. Her visual acuity improved without a worsening of diabetic retinopathy. Since the increased IGF-1 production in systemic circulation and local vitreous fluids may be one of the aggravating factors for diabetic retinopathy, our patient's acromegaly complicated with severe retinopathy presented an opportunity for multimodal management in close collaboration with an ophthalmologist, neurosurgeon, and endocrinologist. Our literature review revealed that the estimated prevalence of diabetic retinopathy in cases of acromegaly associated with diabetes mellitus is 12.5-42.9%.

Abstract
Developing new varieties in fruit and tea breeding programs is very costly and labor-intensive. Thus, establishing a variety discrimination system is important for protecting breeders’ rights and producers’ profits. Simple sequence repeat (SSR) databases that can be utilized for both next-generation sequencing (SSR-GBS) and polymerase chain reaction–capillary electrophoresis (PCR-CE) would be very useful in variety discrimination. In the present study, SSRs with tri-, tetra- and pentanucleotide repeats were examined in apple, pear and tea. Out of 37 SSRs that showed clear results in PCR-CE, 27 were suitable for SSR-GBS. Among the remaining markers, there was allele dropout for some markers that caused differences between the results of PCR-CE and SSR-GBS. For the selected 27 markers, the alleles detected by SSR-GBS were comparable to those detected by PCR-CE. Furthermore, we developed a computational pipeline for automated genotyping using SSR-GBS by setting a value “α” for each marker, a criterion whether a genotype is homozygous or heterozygous based on allele frequency. The set of 27 markers contains 10, 8 and 9 SSRs for apple, pear and tea, respectively, that are useful for both PCR-CE and SSR-GBS and suitable for automation. The databases help researchers discriminate varieties in various ways depending on sample size, markers and methods.

Abstract
We provide the details of the successful management of a patient with active Cushing's disease complicated with coronavirus disease 2019 (COVID-19) pneumonia. The patient was a 27-year-old Japanese female healthcare worker who was scheduled to undergo pituitary surgery for Cushing's disease. She had been in close contact with an undiagnosed patient infected with COVID-19 and then developed COVID-19 pneumonia. Despite a lack of known risk factors associated with severe COVID-19 infection, the patient's dyspnea worsened and her respiratory condition deteriorated, as indicated by the need for 7 L/min oxygen supply by mask to maintain her oxygen saturation at >90%. Medical treatment was initiated to control hypercortisolism by the 'block and replace' regimen using steroidogenesis inhibitors and hydrocortisone. The COVID-19 pneumonia improved with multi-modal treatment including antiviral therapy. One month later, after a negative severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) test result and with appropriate protection against virus transmission to medical staff in the operating room and daily medical care nurses, trans-sphenoidal surgery was performed by our highly experienced pituitary surgeon. One month after the surgery, the patient's basal ACTH and cortisol levels and urinary free cortisol were all under the detection limit. Surgical remission was expected. Since hypercortisolism due to active Cushing's disease may worsen a COVID-19 infection, multi-disciplinary management that includes appropriate and prompt treatment strategies is mandatory in such cases.

Abstract
BACKGROUND The occipital transtentorial approach (OTA) is a very useful but challenging approach to expose the pineal region because the deep-seated arachnoid membranes usually fold and extend over the great vein of Galen (GVG), leading to dense and poor visibility. In addition, the practical aspects of arachnoid anatomy are not well understood. We aimed to develop a safe surgical procedure for the OTA according to the practical aspects of arachnoid anatomy. METHODS The procedure is shown through an illustrative video of surgery and cadaver. Five cadavers were analyzed for their arachnoid structures and the surgical procedures via the OTA, in strict compliance with legal and ethical requirements. RESULTS All cadavers showed a 2-layered arachnoid structure-one belonging to the occipital lobe, and the other to the cerebellum. According to our cadaveric analysis, the arachnoid attachment of the tentorial apex can be peeled bluntly, with an average distance of 10.2 mm. For our clinical presentation, a pineal tumor with hydrocephalus was detected in a 14-year-old boy. While using the OTA and expanding the deep surgical field, we detached the membrane from the tentorial apex and bluntly peeled it to reveal the deep veins. Finally, gross total removal of the tumor was achieved. CONCLUSIONS A 2-layered arachnoid structure interposes the GVG from above and below the tentorium. The arachnoid membrane below the tentorium can be peeled off bluntly from the GVG to the attachment bundle limited by the penetrating veins. This detachment technique is useful for safe enlargement of the surgical field for the OTA.

Abstract
The Chinese chestnut (Castanea mollissima Bl.) was introduced into Japan about 100 years ago. Since then, a number of Chinese chestnut cultivars and Japanese-Chinese hybrid cultivars have been selected by farmers and plant breeders, but little information has been available about their origins and genetic relationships. A classification based on simple sequence repeat markers was conducted using 230 cultivars including Japanese chestnut (Castanea crenata Sieb. et Zucc.) cultivars originated in Japan, Japanese-Chinese hybrid cultivars, and Chinese chestnut cultivars originated in both Japan and China. First, a search for synonyms (cultivars with identical genotypes) revealed 23 synonym groups among the Chinese chestnut cultivars, and all but one cultivar from each synonym group was omitted from further analyses. Second, genetic structure analysis showed a clear division between Japanese and Chinese chestnut, and most of the Japanese and Chinese cultivars had a simple genetic structure corresponding to the expected species. On the other hand, most Japanese-Chinese hybrid cultivars had admixed genetic structure. Through a combination of parentage and chloroplast haplotype analyses, 16 of the 18 hybrid cultivars in this study were inferred to have parent-offspring relationships with other cultivars originated in Japan. Finally, Bayesian clustering and chloroplast haplotype analysis showed that the 116 Chinese chestnut cultivars could be divided into two groups: one originated in the Hebei region of China and the other originated in the Jiangsu and Anhui regions of China. The Chinese chestnut cultivars selected in Japan showed various patterns of genetic structure including Hebei origin, Jiangsu or Anhui origin, and admixed. The chestnut cultivar genetic classifications obtained in this study will be useful for both Japanese and Chinese chestnut breeding programs.

Abstract
Bacterial spot (caused by Xanthomonas arboricola pv. pruni) is a serious disease and difficult to control in peach cultivation, and inheritance manner of susceptibility is unclear. Five hundred and fourteen offspring and their parents from 27 peach full-sib families were evaluated for susceptibility to bacterial spot by evaluating lesion length value (LLV) after artificial inoculation to shoots from trees growing in the field. Brazilian cultivars including 'Chimarrita' and selections derived from them had notably lower LLVs ranging from 0.302 to 0.490 than those from Japanese cultivars/selections ranging from 0.514 to 1.295. Family means in offspring crossed between Brazilian cultivars/selections (low LLVs) and other cultivars/selections (high LLVs) showed rather low LLVs, whose values were close to Brazilian cultivar/selection parents. These results suggested that the susceptibility was controlled by single major gene and that the Brazilian and Japanese cultivar/selection parents showed dominant and recessive homozygotes, respectively. In contrast, the LLVs of family means were very high ranging from 0.719 to 1.194 in offspring population derived from crosses among Japanese cultivars. Repeated backcrosses of Brazilian cultivars/selections with Japanese cultivars/selections having high fruit quality are proposed as an effective method for developing new cultivars combining bacterial spot resistance and fruit quality in Japan.

Abstract
Melting-flesh peaches produce large amounts of ethylene, resulting in rapid fruit softening at the late-ripening stage. In contrast, stony hard peaches do not soften and produce little ethylene. The indole-3-acetic acid (IAA) level in stony hard peaches is low at the late-ripening stage, resulting in low ethylene production and inhibition of fruit softening. To elucidate the mechanism of low IAA concentration in stony hard peaches, endogenous levels of IAA and IAA intermediates or metabolites were analysed by ultra-performance liquid chromatography-tandem mass spectrometry. Although the IAA level was low, the indole-3-pyruvic acid (IPyA) level was high in stony hard peaches at the ripening stage. These results indicate that YUCCA activity is reduced in ripening stony hard peaches. The expression of one of the YUCCA isogenes in peach, PpYUC11, was suppressed in ripening stony hard peaches. Furthermore, an insertion of a transposon-like sequence was found upstream of the PpYUC11 gene in the 5'-flanking region. Analyses of the segregation ratio of the stony hard phenotype and genotype in F1 progenies indicated that the transposon-inserted allele of PpYUC11, hd-t, correlated with the stony hard phenotype. On the basis of the above findings, we propose that the IPyA pathway (YUCCA pathway) is the main auxin biosynthetic pathway in ripening peaches of 'Akatsuki' and 'Manami' cultivars. Because IAA is not supplied from storage forms, IAAde novo synthesis via the IPyA pathway (YUCCA pathway) in mesocarp tissues is responsible for auxin generation to support fruit softening, and its disruption can lead to the stony hard phenotype.

Abstract
BACKGROUND It is very rare for a choroid plexus tumor to occur intraparenchymally in the absence of a relation to the choroid plexus. CLINICAL PRESENTATION A case of cerebral intraparenchymal choroid plexus tumor in a 30-year-old woman presenting with left hemiparesis is described. Brain magnetic resonance imaging depicted a large cystic mass in the right frontal lobe. Tumor resection was performed by right frontal craniotomy. No connection with the choroid plexus was observed during the operation. Histologically, the tumor exhibited a glandular structure with a papillary pattern suggesting a neoplasm of epithelial origin. Immunohistochemical analyses revealed the tumor as an atypical choroid plexus papilloma. CONCLUSION Immunohistochemical findings, especially regarding Kir7.1, are very important for the differential diagnosis of cerebral intraparenchymal choroid plexus tumors from metastatic tumors. The present case reveals that an atypical choroid plexus papilloma can occur intraparenchymally without an association with the choroid plexus. Intraparenchymal atypical choroid plexus papillomas may have previously been diagnosed incorrectly as metastatic adenocarcinomas of unknown origin.

Abstract
BACKGROUND Although prestorage leucoreduction (LR) of blood components for transfusion has gained favour around the world, evidence of its beneficial clinical effects is ambiguous. STUDY DESIGN AND METHODS To reveal whether leucocytes and/or platelets in transfused blood are related to transfusion-related adverse effects, a prospective randomized crossover study was performed on patients who donated autologous blood prior to elective surgery. Among 1487 primary enrolees, a total of 192 patients undergoing two-stage, bilateral total hip arthroplasty were randomized to receive autologous blood that was either prestorage leucoreduced, or not, for the first procedure. For the second procedure, each patient was crossed over to receive alternatively processed autologous blood. Length of hospital stay served as a primary end-point, with perioperative infectious/thrombotic complications, pre- and postoperative laboratory values, and body temperature serving as secondary endpoints. RESULTS No significant differences emerged between prestorage LR and non-LR cohorts in length of hospital stay, as well as perioperative infectious/thrombotic complications, postoperative body temperature and duration of fever. Postoperative laboratory values including white blood cell counts and C-reactive protein levels had no significant differences. CONCLUSION This study could not prove any superiority of prestorage LR over non-LR for autologous whole blood among patients who underwent total hip arthroplasty.

Abstract
Self-compatible mutants of self-incompatible crops have been extensively studied for research and agricultural purposes. Until now, the only known pollen-part self-compatible mutants in Rosaceae subtribe Pyrinae, which contains many important fruit trees, were polyploid. This study revealed that the pollen-part self-compatibility of breeding selection 415-1, a recently discovered mutant of Japanese pear (Pyrus pyrifolia) derived from γ-irradiated pollen, is caused by a duplication of an S-haplotype. In the progeny of 415-1, some plants had three S-haplotypes, two of which were from the pollen parent. Thus, 415-1 was able to produce pollen with two S-haplotypes, even though it was found to be diploid: the relative nuclear DNA content measured by flow cytometry showed no significant difference from that of a diploid cultivar. Inheritance patterns of simple sequence repeat (SSR) alleles in the same linkage group as the S-locus (LG 17) showed that some SSRs closely linked to S-haplotypes were duplicated in progeny containing the duplicated S-haplotype. These results indicate that the pollen-part self-compatibility of 415-1 is not caused by a mutation of pollen S factors in either one of the S-haplotypes, but by a segmental duplication encompassing the S-haplotype. Consequently, 415-1 can produce S-heteroallelic pollen grains that are capable of breaking down self-incompatibility (SI) by competitive interaction between the two different S factors in the pollen grain. 415-1 is the first diploid pollen-part self-compatible mutant with a duplicated S-haplotype to be discovered in the Pyrinae. The fact that 415-1 is not polyploid makes it particularly valuable for further studies of SI mechanisms.

Abstract
PURPOSE To understand the influence of disease and treatment on the health-related quality of life (HRQOL) of children with brain tumors, compared to the HRQOL of children with other cancers, from the viewpoints of children and parents. METHODS A total of 133 children aged 5-18 years and 165 parents of children aged 2-18 completed questionnaires of the Pediatric Quality of Life Inventory Cancer Module (Pain and Hurt, Nausea, Procedural Anxiety, Treatment Anxiety, Worry, Cognitive Problems, Perceived Physical Appearance, and Communication scales); higher scores indicate a better HRQOL. The Cancer Module scores, weighted by age and treatment status, were compared to those obtained in a previous study of children with other cancers (mostly leukemia). RESULTS The weighted mean scores for Pain and Hurt (effect size d = 0.26) and Nausea (d = 0.23) from child reports and the scores for Nausea (d = 0.28) from parent reports were higher for children with brain tumors than scores for children with other cancers. The scores for Procedural Anxiety (d = -0.22) and Treatment Anxiety (d = -0.32) from parent reports were lower for parents of children with brain tumors than the scores for parents of children with other cancers. The child-reported Pain and Hurt score of the Cancer Module was higher (d = 0.29) and in less agreement (intraclass correlation coefficient = 0.43) with scores from the Brain Tumor Module, indicating that assessments completed with the Cancer Module misesteem pain and hurt problems in children with brain tumors. CONCLUSIONS The profiles of cancer-specific HRQOL in children with brain tumors differ from those of children with other cancers; we therefore suggest that these children receive specific psychological support.

Abstract
Although the potential of marker-assisted selection (MAS) in fruit tree breeding has been reported, bi-parental QTL mapping before MAS has hindered the introduction of MAS to fruit tree breeding programs. Genome-wide association studies (GWAS) are an alternative to bi-parental QTL mapping in long-lived perennials. Selection based on genomic predictions of breeding values (genomic selection: GS) is another alternative for MAS. This study examined the potential of GWAS and GS in pear breeding with 76 Japanese pear cultivars to detect significant associations of 162 markers with nine agronomic traits. We applied multilocus Bayesian models accounting for ordinal categorical phenotypes for GWAS and GS model training. Significant associations were detected at harvest time, black spot resistance and the number of spurs and two of the associations were closely linked to known loci. Genome-wide predictions for GS were accurate at the highest level (0.75) in harvest time, at medium levels (0.38-0.61) in resistance to black spot, firmness of flesh, fruit shape in longitudinal section, fruit size, acid content and number of spurs and at low levels (<0.2) in all soluble solid content and vigor of tree. Results suggest the potential of GWAS and GS for use in future breeding programs in Japanese pear.

Abstract
Chondrosarcomas of the skull base are locally aggressive tumours, and radical surgical resection is often difficult because of involvement of important neural structures in the skull base. We report the successful total resection of a huge skull base chondrosarcoma extending both intra- and extracranially. The tumour involved the left mastoid process, entire petrous bone, jugular foramen, posterior fossa and the parapharyngeal space. Since the facial nerve in the fallopian canal was totally involved by the tumour, the nerve was sacrificed and reconstructed using a great auricular nerve graft. The removal of the tumour was radical and complete. The functional recovery of the reconstructed facial nerve was excellent. The patient has almost fully recovered from the other neurological symptoms and has been free of tumour recurrence for 4 years after surgery.

Abstract
OBJECTIVE This single-arm, open-label, Phase II study evaluated the efficacy and safety of single-agent bevacizumab, a monoclonal antibody against vascular endothelial growth factor, in Japanese patients with recurrent malignant glioma. METHODS Patients with histologically confirmed, measurable glioblastoma or World Health Organization Grade III glioma, previously treated with temozolomide plus radiotherapy, received 10 mg/kg bevacizumab intravenous infusion every 2 weeks. The primary endpoint was 6-month progression-free survival in the patients with recurrent glioblastoma. RESULTS Of the 31 patients enrolled, 29 (93.5%) had glioblastoma and 2 (6.5%) had Grade III glioma. Eleven (35.5%) patients were receiving corticosteroids at baseline; 17 (54.8%) and 14 (45.2%) patients had experienced one or two relapses, respectively. The 6-month progression-free survival rate in the 29 patients with recurrent glioblastoma was 33.9% (90% confidence interval, 19.2-48.5) and the median progression-free survival was 3.3 months. The 1-year survival rate was 34.5% with a median overall survival of 10.5 months. There were eight responders (all partial responses) giving an objective response rate of 27.6%. The disease control rate was 79.3%. Eight of the 11 patients taking corticosteroids at baseline reduced their dose or discontinued corticosteroids during the study. Bevacizumab was well-tolerated and Grade ≥3 adverse events of special interest to bevacizumab were as follows: hypertension [3 (9.7%) patients], congestive heart failure [1 (3.2%) patient] and venous thromboembolism [1 (3.2%) patient]. One asymptomatic Grade 1 cerebral hemorrhage was observed, which resolved without treatment. CONCLUSION Single-agent bevacizumab provides clinical benefit for Japanese patients with recurrent glioblastoma.

Abstract
A 2-year-old female presented with a rare case of recurrent giant cell tumor affecting the frontal bone. She had already undergone partial removal twice at the ages of 14 and 18 months. The tumor was located in the frontal bone, expanding to the ethmoid and orbital bones, and invading the frontal base dura mater. The tumor was totally removed including the surrounding bone and frontal base dura mater. No local recurrence and metastasis were observed at 18 months after the last operation. Most giant cell tumors occur in the epiphyses of long bones and are rare in the cranio-facial bone. These tumors usually affect young adults and few pediatric cases are reported.

Abstract
We developed retrotransposon-based insertional polymorphism (RBIP) markers based on the long terminal repeat (LTR) sequences of copia-like retrotransposon Ppcrt4 and flanking genome sequences, which were derived from 454 sequencing data from Japanese pear (Pyrus pyrifolia) 'Hosui'. Out of 40 sequences including both LTR and flanking genome regions, we developed 22 RBIP markers and used them for DNA profiling of 80 pear cultivars: 64 Japanese, 10 Chinese (Pyrus ussuriensis) and 6 European (Pyrus communis). Three RBIP markers were enough to differentiate 'Hosui' from the other Japanese pear cultivars. The 22 RBIP markers could also distinguish 61 of the 64 Japanese pear cultivars. European pears showed almost no amplification of the 22 RBIP markers, which might suggest that retrotransposons had transposed during Asian pear evolution or reflect the genetic relationship between Asian and European pears. Sixteen of the RBIP markers could be positioned on a genetic linkage map of 'Hosui'. The RBIP loci were distributed in 10 linkage groups, and some loci were very closely located within the same linkage group. The information obtained will be applicable to developing cultivar-specific RBIP marker sets in plants.

Abstract
This report describes an alternative approach to the infratemporal fossa lesions through a lateral zygomato-temporal craniotemy, which modifies the extradural temporopolar technique for cavernous sinus surgery. First, an L-shaped osteotomy of the zygoma from the frontozygomatic suture attaching the zygomatre arch and low positioned temporal cramotomy are made. Through this zygomato-temporal craniotomy and orbitotemporal drilling, leaving the lateral orbital rim and orbital roof intact, skeletonization of the foramens rotundum and ovale are carried out. The key element of this infratemporal exposure is the dissection and mobilization of the trigeminal nerve, trigeminal second branch rostrally, and the third branch caudally, which facilitates a wide exposure of the infratemporal fossa with preserving trigeminal function. The corridor between the mobilized trigeminal branches provides direct access to the lateral and medial pterygoid plate, internal maxillary artery, sphenoid and maxillary sinuses, maxilla and, finally, the parapharyngeal area. Our experiences have demonstrated that this lateral transzygomatic-transtemporal exposure is satisfactory for use with infratemporal fossa tumors. This approach has an advantage for cranial-base exposure with decreased risks of cosmetic deformity and of trigeminal nerve dysfunction.

Abstract
OBJECTIVES To evaluate the risk factors for perioperative complications among patients undergoing craniofacial resection for the treatment of skull base tumors. DESIGN Retrospective analysis. PARTICIPANTS The study group comprised 29 patients with skull base tumors (22 malignant and 7 benign) who underwent 30 craniofacial resections at Hokkaido University Hospital between 1989 and 2006. Of these cases, 21 had undergone prior treatment by radiation (16 cases), surgery (7 cases), or chemotherapy (1 case). Moreover, 19 needed extended resection involving the dura (11 cases), brain (5 cases), orbit (12 cases), hard palate (5 cases), skin (3 cases), or cavernous sinus (2 cases). MAIN OUTCOME MEASURES Perioperative complications and risk factor associated with their incidence. RESULTS Perioperative complications occurred in 12 patients (40%; 13 cases). There was a significant difference between complication rates for cases with and without prior therapy (52.4% vs. 11.1%). The complication rate for dural resection cases was 81.8%. There was a significant difference between complication rates for cases with and without dura resection. No postoperative mortality was reported. CONCLUSIONS Craniofacial resection is a safe and effective treatment for skull base tumors. However, additional care is required in patients with extended resection (especially dural) and those who have undergone prior therapy.

Abstract
The traditional sublabial transsphenoidal approach offers a limited operative field. This report describes a simple surgical technique to widen the sublabial transsphenoidal window to access the midline lesions from the planum sphenoidale to the lower clivus. This technique was developed on the basis of clinical experience and on data obtained by cadaveric dissection study. Following a sublabial incision and separation of the bilateral septal mucosa, a small Sigma-shape osteotomy of the maxilla, including the anterior nasal spine, was performed with a surgical saw. The width of the entrance to the nasal cavity ranged from 32 to 38 mm. Although the plexus of the anterior superior alveolar nerve was partially cut, our clinical experience revealed no significant sensory loss of the incisors after the Sigma-shape osteotomy. The nasal orests of the maxilla and palatine bone were drilled out, and the roof of the nasopharynx was then incised to expose the lower clival bone. Although extradural sellar or clival lesions were the focus of this approach, the intradural anatomical structures examined by cadaveric study were presented. The extended transsphenoidal approach with Sigma-shape osteotomy of the maxilla is a simple technique and provides widened access to the sellar and clival regions.

Abstract
This article details our experience with 24 cases of anterior skull base reconstruction after tumor resection. They were classified into four types according to the resected region. In 11 cases of type I resection, the orbital part of frontal bone and/or cribriform plate of ethmoid bone were resected. In two cases of type II resection, the orbital contents and partial orbital bone were resected with the addition of type I. In five cases of type III resection, the maxillary bone was resected with the addition of type II. In six cases of type IV resection, the zygomatic bone and/or facial skin were resected with the addition of type III. The tumor originating from intracranial region was 25% of this series and all of them belonged to type I. The tumor originating from extracranial region tumor was 75% and its resected region was more extensive. In type I and II resections, the cranial flap, radial forearm free flap, or a combination of the two was used for reconstruction. The rectus abdominis myocutaneous/muscle free flap was used for reconstruction of massive defects in type III and IV defects. Total incidence of postoperative complications was 16.7%. Donor site deformity of the cranial flap at the frontal and temporal region in types I and II resections and facial contour deformity in zygomatic region and defect of upper and/or lower palpebra in type IV resection were major problems with postoperative facial appearance. Although use of the rectus abdominis myocutaneous free flap combined with costal cartilages improved the midfacial contour, palpebral reconstruction remained an unsolved problem in reconstructive skull base surgery. The reconstructive goals in skull base surgery are not only to obtain safe and reliable skull base reconstruction but also to restore the facial appearance postoperatively.

Abstract
A 1-year-old female infant presented with congenital giant, hairy and pigmented nevi. MRI scan as screening test revealed a cerebellar tumor. A diagnosis of provisional neurocutaneous melanosis was made on the basis of the patient's MRI and physical findings. At her 6 years of age, MRI revealed the tumor grown up to 3 cm diameter in 5 years. The cerebellar tumor was removed partially using the occipital transtentorial approach for tissue diagnosis. The color of the cerebellar tumor was whitish and contained neither benign nor malignant melanocyte. Pathological examination revealed diffuse astrocytoma. Finally residual cerebellar tumor was totally removed at a second surgical resection. To our knowledge, this is the first patient to be reported with astrocytoma complicated giant skin nevus except neurocutaneous syndrome cases.

Abstract
We present a modified method for reconstruction of calvarial bone defects for patients with a history of infectious complications. Three patients who had experienced implanted bone infections underwent reconstruction of calvarial bone defect. For reconstruction of the calvarial bone defects, autologous split calvarial bone grafts were used to cover the calvarial bone defect. The full or half layered fronto-parietal bone used as implants were fixed with titanium mini-plates for primary bone defect site, while the new bone defect site caused by getting autologous bone graft were covered with titanium mesh plates assisted by residual half layered calvarias. The average follow-up span of patients was 64 months. Evaluated clinical and radiologic results are stable, showing no measurable side effects. Split calvarial bone graft in combination with titanium mesh plates is recommended in patients with a history of infection or high risk of infection.

Abstract
A 77-year-old woman with cognitive impairment and multifocal progressive lesions on brain MRI was admitted to our hospital. Analysis of blood and cerebrospinal fluid showed no evidence of infection, autoimmune disease, or metabolic abnormalities. Histological examination of biopsied tissue from a lesion in the right frontal lobe revealed an abnormally increased glial cell density with enlarged nuclei and a high MIB-1 index. These pathological findings coupled with her progressive clinical history indicated a diagnosis of gliomatosis cerebri. General characteristics of gliomatosis cerebri include diffuse infiltrative lesions in neuroimaging with or without mass effect. However, the present case showed unusual multifocal manifestations in brain MRI. Therefore, histopathological examination must be taken into account for a proper diagnosis.

Abstract
Most fruit trees in the Rosaceae exhibit self-incompatibility, which is controlled by the pistil S gene, encoding a ribonuclease (S-RNase), and the pollen S gene at the S-locus. The pollen S in Prunus is an F-box protein gene (SLF/SFB) located near the S-RNase, but it has not been identified in Pyrus and Malus. In the Japanese pear, various F-box protein genes (PpSFBB(-α-γ)) linked to the S-RNase are proposed as the pollen S candidate. Two bacterial artificial chromosome (BAC) contigs around the S-RNase genes of Japanese pear were constructed, and 649 kb around S(4)-RNase and 378 kb around S(2)-RNase were sequenced. Six and 10 pollen-specific F-box protein genes (designated as PpSFBB(4-u1-u4, 4-d1-d2) and PpSFBB(2-u1-u5,) (2-d1-d5), respectively) were found, but PpSFBB(4-α-γ) and PpSFBB(2-γ) were absent. The PpSFBB(4) genes showed 66.2-93.1% amino acid identity with the PpSFBB(2) genes, which indicated clustering of related polymorphic F-box protein genes between haplotypes near the S-RNase of the Japanese pear. Phylogenetic analysis classified 36 F-box protein genes of Pyrus and Malus into two major groups (I and II), and also generated gene pairs of PpSFBB genes and PpSFBB/Malus F-box protein genes. Group I consisted of gene pairs with 76.3-94.9% identity, while group II consisted of gene pairs with higher identities (>92%) than group I. This grouping suggests that less polymorphic PpSFBB genes in group II are non-S pollen genes and that the pollen S candidates are included in the group I PpSFBB genes.

Abstract
OBJECTIVE (11)C-Methionine positron emission tomography (MET-PET) has been used to distinguish brain tumor recurrence from radiation necrosis. Because the spatial resolution of conventional PET scanners is low, partial volume effect (PVE) may decrease the detectability of small tumor recurrence. The aim of this study is to investigate the diagnostic value of MET-PET upon semiquantitative analyses in particular PVE-affected small lesions. METHODS First, we performed a phantom experiment to investigate what size lesion is affected by PVE. This study included 29 patients (33 lesions) suspected of recurrent brain tumors by magnetic resonance imaging (MRI) after radiation therapy. All of them received MET-PET. Semiquantitative analysis was performed using maximum standardized uptake value (SUVmax) and lesion-versus-normal ratio (L/N ratio). ROC analysis was also assessed about the diagnostic value of MET-PET. RESULTS From the result of the phantom experiment, lesions smaller than 20 mm in brain mode or smaller than 30 mm in whole-body mode were defined as PVE-affected lesions. Histological analysis or clinical follow-up confirmed the diagnosis of tumor recurrence in 22 lesions, and radiation necrosis in 11 lesions. L/N ratios of recurrence and necrosis for overall lesions were 1.98 ± 0.62 and 1.27 ± 0.28, respectively (p < 0.01). In the PVE-affected lesions, L/N ratio for recurrence (1.72 ± 0.44) was also significantly higher than that for necrosis (1.20 ± 0.11) (p < 0.01). On the ROC analysis for the PVE-affected lesions, the area under the curve for L/N ratio (0.897) was significantly higher than that for SUVmax (0.718) (p < 0.05). These areas under the curve were almost equal to that of overall lesions for L/N ratio (0.886) and for SUVmax (0.738). CONCLUSIONS Semiquantitative analysis of MET provided high diagnostic value even for PVE-affected small lesions. MET-PET enables early diagnosis of recurrence of brain tumor in the follow-up after the radiation therapy.

Abstract
PURPOSE Personalized selection of suitable peptides for patients could offer a novel approach to developing cancer vaccines that boost anticancer immunity. We present the results of a phase I trial of 14 kinds of vaccine candidates (ITK-1) in patients with recurrent or progressive glioblastoma multiforme (GBM). PATIENTS AND METHODS From January 2006 to January 2008, 12 patients from eight Japanese hospitals who were positive for human leukocyte antigen-A24, including 10 patients refractory to temozolomide (TMZ), were enrolled. The dose escalation trial included three dose groups (1, 3, and 5 mg) to determine the safety and tolerability of ITK-1 peptides. Immunologic response was monitored by measuring levels of cytotoxic T-lymphocyte precursors and peptide-specific immunoglobulin G. In another ITK-1 phase I trial for advanced prostate cancer, the vaccination schedule was skipped or discontinued in all three patients receiving the highest dose (5 mg/peptide) because of injection site reactions. This trial was therefore ended without enrollment for the highest dose, and data were analyzed by intention to treat. RESULTS No serious adverse drug reactions were encountered, and treatment was well tolerated. The vaccine induced dose-dependent immune boosting. The recommended dose of ITK-1 peptides is 3 mg/peptide. CONCLUSION Personalized vaccination with ITK-1 peptides could be recommended in further stages of clinical trials. The safety and increased frequency of immune boosting offers potential clinical benefits in cases of recurrent or progressive GBM, even in TMZ-refractory settings.

Abstract
Our therapeutic strategy for the petroclival meningioma (PCM) allows for observation for asymptomatic and microsurgery for symptomatic cases. For evaluation of this strategy, functional status assessed by the Karnofsky Performance Score (KPS) in each group was retrospectively analyzed. The records of 29 patients with PCMs were reviewed. Fifteen patients were enrolled in the observation group and the median follow-up period was 40 months (range, 5-170). Eighteen patients underwent operative procedures for resection of PCMs and the median follow-up period was 65.5 months (range, 9-194). In the observation group, 60% of the cases showed radiological tumor growth during the follow-up period. There was functional deterioration in 47% of the cases. The growing tumors were unpredictable. In the microsurgery group, gross tumor resection was accomplished in 22% of the cases. The surgical morbidity rate, a KPS less than 80, at three months after surgery and at the time of the last follow-up was 56% and 6%, respectively. Postoperative KPS at three months after surgery was significantly worse than preoperative KPS. However, most of the patients with a worse KPS had recovered at the time of the last follow-up and they had a favorable functional outcome. Regarding the degree of the KPS change, there was no significant difference between the observation and the microsurgery groups during the follow-up periods. Based on the functional outcomes of each group, our therapeutic strategy for PCMs was shown to be reasonable and warranted.

Abstract
Peduncular hallucinosis is a rare phenomenon characterized by visual hallucination consisting of vivid, colored image of people, animals, scenes or geometric patterns. In most of the cases the hallucination is accompanied by sleeping disorder, and is by the patient recognized as not being real. It can be observed mainly in patients with thalamic/midbrain vascular disease, and is less frequently seen in brain stem tumor. The damage of the ascending reticular activating system by brain stem compression causing dream activity releasing what is normally suppressed during wakefulness is thought to be the mechanism of peduncular hallucinosis. The authors report a 13-year-old female presenting peduncular hallucinosis due to brainstem compression by a pineocytoma. The patient had a 3-month history of complex visual hallucination and slight somnolence. The hallucination mainly consisted of TV game characters, animals, and vegetables which were colorful and vivid. She was well oriented and realized that the hallucination was not real. MRI showed a pineal mass compressing the quadrigeminal plate inferiorly. There was mild obstructive hydrocephalus due to aqueduct stenosis. The tumor was totally removed and was pathologically diagnosed as pineocytoma. After the surgery, the hallucination ameliorated remarkably. Although the administration of benzodiazepine exacerbated the hallucination and sleep disorder, oral carbamazepine was clearly effective and produced nearly complete disappearance of hallucination. To the best of our knowledge, this is the first report of peduncular hallucinosis caused by quadrigeminal plate compression by a pineal tumor.

Abstract
The histopathological entity 'germ cell tumor' (GCT) encompasses a number of histological subtypes. Pineal GCTs can be grossly divided into three categories: those with a good, intermediate, and poor prognostic. Germinoma and mature teratoma are curable and classified into the good prognostic group, whereas embryonal carcinoma, yolk sac tumor, and other highly malignant neoplasms leave patients with a dismal prognosis. There are other types of GCT that have an intermediate prognosis, such as immature teratoma. Only mature teratomas are curable by surgical resection alone; the other types require adjuvant therapy. To plan a surgical strategy, then eurosurgeon has to acquire enough knowledge of the effect of adjuvant therapies and biological behavior of the GCTs. Germinoma can be cured by low-dose radiotherapy in combination with chemotherapy, and nowadays needs only to be biopsied. Other tumors, such as highly malignant tumors need a sophisticated combination therapy that includes surgery, craniospinal radiation therapy, and intensive chemotherapy. An appropriate neoadjuvant therapy prior toradical surgical removal will remarkably reduce the surgical risk. The goal of treatment should be tightly focused on the reduction of posttreatment sequelae, including surgical morbidity, and not on a complete microsurgical resection.

Abstract
For children with craniosynostosis presenting intracranial hypertension and facial hypoplasia, different techniques have been used. Commonly, an initial frontoorbital advancement to expand a tight cranium volume was followed by Le Fort III osteotomy to repair midface abnormalities several months later. The 2-stage surgeries were unified into a 1-step procedure to optimize treatment. We here report results of frontofacial monobloc advancement, applying gradual distraction by a rigid external distraction device. Three patients were treated with excellent functional and cosmetic outcome with high rate of patient satisfaction. There was no remarkable complication.
