Abstract
BACKGROUND Glioblastomas comprise heterogeneous cell populations with dynamic, bidirectional plasticity between treatment-resistant stem-like and treatment-sensitive differentiated states, with treatment influencing this process. However, current treatment protocols do not account for this plasticity. Previously, we generated a mathematical model based on preclinical experiments to describe this process and optimize a radiation therapy fractionation schedule that substantially increased survival relative to standard fractionation in a murine glioblastoma model. METHODS We developed statistical models to predict the survival benefit of interventions to glioblastoma patients based on the corresponding survival benefit in the mouse model used in our preclinical study. We applied our mathematical model of glioblastoma radiation response to optimize a radiation therapy fractionation schedule for patients undergoing re-irradiation for glioblastoma and developed a first-in-human trial (NCT03557372) to assess the feasibility and safety of administering our schedule. RESULTS Our statistical modeling predicted that the hazard ratio when comparing our novel radiation schedule with a standard schedule would be 0.74. Our mathematical modeling suggested that a practical, near-optimal schedule for re-irradiation of recurrent glioblastoma patients was 3.96 Gy × 7 (1 fraction/day) followed by 1.0 Gy × 9 (3 fractions/day). Our optimized schedule was successfully administered to 14/14 (100%) patients. CONCLUSIONS A novel radiation therapy schedule based on mathematical modeling of cell-state plasticity is feasible and safe to administer to glioblastoma patients.

Abstract
Nanodiamond/polyamide (ND/PA) nanocomposite was examined with infrared (IR) microscopy and time-domain nuclear magnetic resonance (TD-NMR) to elucidate in detail the interphase between amino functionalized ND (ND-NH2) and PA 66. An IR image of the ND/PA nanocomposite suggested the uniform nanoscale distribution of the ND-NH2 particles thanks to the spherical shape and accessible external surface of ND terminated with reactive amino groups. On the other hand, a substantial level of change was observed in T2 decay curves when the ND-NH2 particles were incorporated in the PA 66. The fine features of the thermally induced changes in the decay curves were readily analyzed with the two-trace two-dimensional (2T2D) correlation method. The variation in the asynchronous correlation intensity indicated that the changes observed in the mechanical properties of the ND/NH2 may be attributed to the development of crosslinking between tie chains in the amorphous region via the interaction between the ND-NH2 and PA 66. Accordingly, such firm links have a substantial effect in preventing the displacement of the amorphous domain, which eventually increases the Young's modulus but reduces the ductility of the PA.

Abstract
The interfacial strength of polystyrene (PS) with and without PS oligomers in contact with a glass substrate was examined to determine the relationship between the interfacial aggregation state and adhesion. The shear bond strength and adsorbed layer thickness of neat PS exhibited a similar dependence on the thermal annealing time: they increased to constant values within almost the same time. This implies that the adhesion of the polymer is closely related to the formation of an adsorbed layer at the adhesion interface. Nevertheless, in the case of PS with a small amount of oligomer, the shear bond strength decreased, while the adsorbed layer thickness was almost the same as that of neat PS. Based on the results of interfacial analyses, we propose that the interfacial segregation of the oligomer reduced the entanglement between the interfacial free chains in the adsorbed layer and the bulk chains.

Abstract
Surgical removal of large jugular foramen schwannomas with intra- and extracranial extension is challenging. The treatment goal is a gross total resection of the tumor without causing surgical complications, including facial nerve paresis, hearing disturbance, dysphagia, hoarseness, and cerebrospinal fluid (CSF) leakage, in addition to the brain stem injury. We present a surgical video in a patient with a dumbbell-shaped glossopharyngeal schwannoma. The combination of posterior fossa craniotomy, mastoidectomy, and unroofing of the jugular foramen with high cervical exposure was selected. Although transposition of the mastoid segment of the facial nerve provides an excellent surgical corridor, it may affect normal facial nerve function. Sufficient drilling of the infralabyrinthine, retrofacial area of the mastoid without facial nerve transposition is important for the safe gross total removal of the tumor. Subcapsular removal behind the jugular vein is also important for preservation of the lower cranial nerve functions. The patient underwent a gross total removal of the tumor ( Figs. 1 and 2 ). Facial nerve function was preserved and hearing disturbance improved. Although dysphagia and hoarseness complicated postoperatively, he became able to take foods orally 16 days after the surgery. In summary, successful removal of a large dumbbell-shaped jugular foramen tumor can be completed via infralabyrinthine, retrofacial, and transjugular approach without facial nerve transposition.

Abstract
We present the case of a 58-year-old Japanese woman with a natural killer T (NK/T)-cell lymphoma complicated by brain abscess. NK/T-cell lymphomas represent a rare type of lymphoma derived from either activated NK cells or, rarely, cytotoxic T cells. They are aggressive Epstein-Barr virus (EBV)-associated lymphomas that involve mainly the nasal cavity. Brain abscess associated with primary extranodal nasal-type NK/T-cell lymphoma is extremely uncommon: to our knowledge, this is the first reported case of this lymphoma with brain abscess as the initial clinical manifestation. Endoscopic surgery was performed for definitive diagnosis under intraoperative navigation system. Chemotherapy followed by radiotherapy was performed and was effective: 72 months later the tumor has not recurred. Recommendations of endoscopic management for diagnosis and treatment of this rare neoplasm are discussed.

Abstract
OBJECTIVES The ASSR is used widely as an objective measurement of hearing in clinical settings because of its high frequency specificity. The recruitment phenomenon is generally detected using subjective evaluations which require direct communication with the patient. If the recruitment phenomenon can be detected with ASSR, it would facilitate diagnosis in patients with developmental disorders and infants. SUBJECTS AND METHODS We examined 2 groups of subjects: 10 subjects with unilateral hearing impairment in whom the recruitment phenomenon was detected by the alternate binaural loudness balance test and 12 normal subjects. We compared the relationships between the ASSR response and the stimulus sound pressure level in the 2 groups using the 80-Hz ASSR. RESULTS The amplitude of ASSR was significantly higher in the impaired ear in hearing-impaired subjects compared to a normal ear in normal subjects. The latency of ASSR was significantly shorter in the impaired ear in hearing-impaired subjects than in the normal ear in the normal subjects. CONCLUSION This study showed that the recruitment phenomenon caused the higher amplitude and the shorter latency observed in hearing-impaired subjects in the 80-Hz auditory steady-state response (ASSR) in comparison with normal subjects.

Abstract
Background The far lateral approach includes exposure of the C1 transverse process, vertebral artery, posterior arch of the atlas, and occipital condyle. We designed a method for systematic muscular-stage dissection and present our experience with this approach. Operative Methods We used a horseshoe scalp flap that was reflected downward and medially. The lateral muscle layers were separated layer to layer to expose the suboccipital triangle. The medial muscle layers were separated in the midline and reflected in a single layer. At this stage, the midline of the C1 process and the foramen magnum were identified. The rectus capitis posterior major muscle was reflected to expose the posterior arch of the atlas. The C1 transverse process and vertebral artery were identified by reflection of the superior oblique muscle. The occipital condyle was separated accordingly. Results We used this method of muscular dissection in 10 patients (foramen magnum meningioma, n = 5; hypoglossal schwannoma, n = 2; others, n = 3). Systematic muscular-stage dissection facilitates identification of the anatomical landmarks with no vertebral artery injury. Gross total removal was obtained in all 9 patients with complex tumors. The patient with vertebral artery dissection successfully underwent proximal clipping. Conclusion Our muscular-stage dissection could contribute to safe and effective surgery for the far lateral approach.

Abstract
OBJECTIVE In advanced temporal bone carcinoma cases, we attempted to preserve as much of the auricle as possible from a cosmetic and functional perspective. Difficulties are associated with selecting an adequate position for reconstructed auricles intraoperatively. We improved the surgical procedure to achieve a good postoperative auricle position. METHODS Nine patients were included in this study. All patients underwent subtotal removal of the temporal bone and resection of the external auditory canal while preserving most of the external ear, and lateral skull base reconstruction was performed with anterolateral thigh flaps. We invented a new device, the auricle localizer, to select the correct position for the replaced external ear. The head skin incision line and two points of three-point pin fixation were used as criteria, and a Kirschner wire was shaped as a basic line to match these criteria. Another Kirschner wire was shaped by wrapping it around the inferior edge of the external ear as the positioning line, and these two lines were then combined. To evaluate the postoperative auricle position, the auricle inclination angle was measured using head frontal cephalogram imaging. RESULTS The external ear on the affected side clearly drooped postoperatively in nonlocalizer cases, whereas this was not obvious in localizer cases. Auricle inclination angles 1 year after surgery significantly differed between these two cases (P = 0.018). CONCLUSION The surgical device, the auricle localizer, is useful for selecting intraoperative accurate auricle positions. The assessment index, the auricle inclination angle, is useful for quantitatively evaluating postoperative results. LEVEL OF EVIDENCE 4 Laryngoscope, 2605-2610, 2018.

Abstract
BACKGROUND Normal pressure hydrocephalus frequently develops after subarachnoid hemorrhage. It can often be difficult, however, to predict shunt dependency. The purpose of this study was to identify predictors of shunt-dependent normal pressure hydrocephalus (SDNPH) after aneurysmal subarachnoid hemorrhage (aSAH). METHODS The incidence of SDNPH in 139 consecutive patients who underwent surgery for aSAH in the Department of Neurosurgery Tokyo Medical and Dental University between January 2008 and December 2011 was evaluated. The patientage, Glasgow Coma Score, World Federation of Neurosurgical Societies grade, Hunt and Hess grade, modified Fisher group, modified Rankin Scale, duration of external drainage of cerebrospinal fluid (CSF), gender, aneurysm location, presence of intraventricular hemorrhage, surgical method (clip or coil), and presence of acute hydrocephalus were analyzed. RESULTS Forty-seven of 139 patients (33.8%) underwent shunt operation. Fifteen of these 47 patients were assessed to have high-pressure hydrocephalus and excluded. Thirty-two SDNPH patients (23.0%) were compared with 84 patients without hydrocephalus (60.4%). An age of 65 years or over (OR 5.51;95%CI 1.97-15.40), a GCS of 13 or less (OR 3.82;95%CI 1.38-10.60), and CSF drainage for a duration of 12 days or more (OR 3.63;95%CI 1.30-10.14) were independently associated with SDNPH. CONCLUSIONS SDNPH after aSAH in our study showed no correlations with three of the parameters previously identified as risk factors for shunt-dependent hydrocephalus, namely, the amount of SAH, the presence of IVH, or acute hydrocephalus. Instead, a longer duration of CSF drainage correlated with SDNPH as an independent factor. These data suggest that a longer duration of CSF drainage may be one of the risk factors for SDNPH after aSAH.

Abstract
OBJECT The majority of sinonasal malignancies present with advanced disease, and cure rates are generally poor. Surgical extirpation remains the mainstay of treatment. In cases of sinonasal malignancy with orbital apex extension, gross-total tumor resection requires orbital exenteration and bony skull base resection around the orbital apex to provide sufficient margins. In this retrospective study, the authors describe their surgical strategy in and technique for orbital exenteration with orbital apex resection in patients at Tokyo Medical and Dental University who had sinonasal malignancy with orbital apex extension. They also analyzed the clinical features of and the results in these patients. METHODS Between February 2001 and August 2012 at the authors' institution, sinonasal malignancy with orbital apex extension was treated using craniofacial tumor resection with orbital exenteration including skull base bone around the orbital apex. The authors describe this technique and analyze the surgical indications, extent of resection, primary tumor location, outcome, pathological findings, and neoadjuvant and adjuvant therapies of the patients who underwent the technique. RESULTS The patients consisted of 12 men and 3 women with a mean age of 47.7 years (range 14-79 years). The longest postoperative follow-up was 9.5 years, and the shortest was 0.67 year (mean 3.0 years). Tumor originated at the ethmoid sinus in 6 patients (40%), maxillary sinus in 5 (33%), nasal cavity in 2 (13%), and orbital cavity and maxillary bone in 1 patient each (7%). Histological analysis of tumor specimens revealed squamous cell carcinoma in 9 patients (60%), rhabdomyosarcoma in 2 (13%), and small cell carcinoma, mucoepidermoid carcinoma, adenoid cystic carcinoma, and Ewing sarcoma in 1 patient each (7%). Two patients experienced recurrences at 1 and 5 months after treatment; these patients died at 5 and 10 months after surgery, respectively. Estimated 5-year recurrence-free survival (RFS) was 86.7%, and estimated 5-year overall survival (OS) was 86.2%; there was no perioperative mortality. None of the patients had new neurological deficits as a result of the surgery, but 5 patients suffered infectious complications from the graft transplanted into the cavity after resection. There were no other perioperative complications. CONCLUSIONS These authors are the first to describe a technique for extended orbital exenteration with orbital apex skull base resection. The technique provided sufficient margins for gross-total resection of the sinonasal malignancy with orbital apex extension. The estimated 5-year OS and RFS rates were high, and the perioperative complication rate was acceptably low, demonstrating the safety and efficacy of this technique.

Abstract
OBJECTIVE The study aimed to assess the usefulness of skull base surgery for large juvenile nasopharyngeal angiofibroma (JNA) with lateral extension to the infratemporal fossa. MATERIALS AND METHODS Eleven cases were enrolled for this study, and the mean age was 17.7 years old (range: 8-32). Six out of 11 cases underwent surgery as an initial treatment, and the other five underwent secondary surgery after initial surgery or radiotherapy in other institutions. The range of extension of tumor, feeding arteries, surgical approach, and treatment outcome were estimated. RESULTS All tumors originated from the sphenopalatine foramen. Based on the imaging study, there was extension to the cavernous sinus observed in eight cases, as well as to the middle cranial fossa (8), orbit (4), and anterior cranial fossa (1). These tumors were diagnosed as Andrews' Stage IVa (3) and IVb (8). However, infiltration into the cavernous sinus was observed in one case only during surgery. Ten tumors were separated carefully from the cavernous sinus or dura and were accurately diagnosed as Stage IIIb. In all cases, the main arterial feeders of the JNAs were branches of the external carotid artery, which were embolized prior to surgery. However, 10 cases were also fed by branches of the internal carotid artery (branches of the ophthalmic artery), in which these arteries could not be embolized. Coronal skin incision (1) and a facial dismasking flap (9) were used, and in one case, wide lateral skin incision with temporary incision of the facial nerve was applied. The orbito-zygomatic approach and its modification was applied to all the cases. Fronto-lateral craniotomy was applied in four cases and lateral craniotomy in seven cases. Total resection was achieved in 10 cases and subtotal resection in one case. No mortality was noted in this series. Temporal trismus was observed in all cases which subsided gradually. Cheek numbness and facial palsy were observed in three and two cases, respectively. CONCLUSION Coupled with craniotomy, tumor removal was successfully carried out in 11 patients with JNAs, which showed large lateral extension. Our surgical strategy is a safe and effective approach for the removal of JNAs with infratemporal fossa extension.

Abstract
CONCLUSIONS Our results confirmed that OK-432 therapy is simple, easy, safe, and effective and can be used as a substitute for surgery in the treatment of ranula extending to the parapharyngeal space. OBJECTIVE The aim of this study was to evaluate the outcome and complications of the OK-432 treatment of patients with ranula extending to the parapharyngeal space. METHODS This was a case series with planned data collection at Yamagata University and Fukase clinic. We tried this therapy in six patients with ranula extending to the parapharyngeal space, between January 2001 and February 2012. We injected OK-432 solution into the lesion with an 18 or 27 gauge needle depending on the patient's condition (location and size of ranula and complications). This treatment was performed on an outpatient basis without hospitalization. RESULTS Disappearance or marked reduction of the lesion were observed in all patients who had this therapy, and local scarring and deformity of the injection sites did not occur in any patients. As side effects, local pain at the injection site and fever (37-39°C) were observed in 40% of the patients who had this therapy, but such problems resolved within a few days.

Abstract
CONCLUSION These results suggest that transforming growth factor (TGF)-beta and periostin could be useful as novel biomarkers and therapeutic targets in IgG4-related disease. OBJECTIVES IgG4-related disease is an uncommon fibrosclerosing and inflammatory mass-forming disease that can be systemic or can affect single organs. To clarify the roles of TGF-beta, periostin, and interleukin (IL)-13 in the pathogenesis of IgG4-related disease, we studied a total of 36 serum and 11 tissue samples from patients with IgG4-related disease. METHODS This was a retrospective clinical study. The patient group consisted of six females and seven males (average age 60 years, range 38-74 years). Serum IgG4 levels, the tissue density of IgG4-positive plasmacytes, and the expression of TGF-beta and periostin in the affected tissues were examined immunohistochemically. RESULTS Serum IgG4 levels were elevated in all patients (mean 776.6, range 185-2820 mg/dl), and IgG4-positive plasmacytes were observed in the affected salivary glands. Seven patients with prominent infiltration of the involved glands with IgG4-positive plasmacytes had fatal systemic complications, including pancreatitis, after swelling of the salivary glands. Overexpression of TGF-beta and periostin was observed in affected tissues obtained from these patients.

Abstract
Ruptured intracranial aneurysms are rare in the pediatric population compared to adults. This has incited considerable discussion on how to treat children with this condition. Here, we report a child with a ruptured saccular basilar artery aneurysm that was successfully treated with coil embolization. A 12-year-old boy with acute lymphoblastic leukemia and accompanying abdominal candidiasis after chemotherapy suddenly complained of a severe headache and suffered consciousness disturbance moments later. Computed tomography scans and cerebral angiography demonstrated acute hydrocephalus and subarachnoid hemorrhage caused by saccular basilar artery aneurysm rupture. External ventricular drainage was performed immediately. Because the patient was in severe condition and did not show remarkable signs of central nervous system infection in cerebrospinal fluid studies, we applied endovascular treatment for the ruptured saccular basilar artery aneurysm, which was successfully occluded with coils. The patient recovered without new neurological deficits after ventriculoperitoneal shunting. Recent reports indicate that both endovascular and microsurgical techniques can be used to effectively treat ruptured cerebral aneurysms in pediatric patients. A minimally invasive endovascular treatment was effective in the present case, but long-term follow-up will be necessary to confirm the efficiency of endovascular treatment for children with ruptured saccular basilar artery aneurysms.

Abstract
Object
Recent evidence suggests that a glioma stem cell subpopulation may determine the biological behavior of tumors, including resistance to therapy. To investigate this hypothesis, the authors examined varying grades of gliomas for stem cell marker expressions and histopathological changes between primary and recurrent tumors.
Methods
Tumor samples were collected during surgery from 70 patients with varying grades of gliomas (Grade II in 12 patients, Grade III in 16, and Grade IV in 42) prior to any adjuvant treatment. The samples were subjected to immunohistochemistry for MIB-1, factor VIII, GFAP, and stem cell markers (CD133 and nestin). Histopathological changes were compared between primary and recurrent tumors in 31 patients after radiation treatment and chemotherapy, including high-dose irradiation with additional stereotactic radiosurgery.
Results
CD133 expression on glioma cells was confined to de novo glioblastomas but was not observed in lower-grade gliomas. In de novo glioblastomas, the mean percentage of CD133-positive glioma cells in sections obtained at recurrence was 12.2% ± 10.3%, which was significantly higher than that obtained at the primary surgery (1.08% ± 1.78%). CD133 and Ki 67 dual-positive glioma cells were significantly increased in recurrent de novo glioblastomas as compared with those in primary tumors (14.5% ± 6.67% vs 2.16% ± 2.60%, respectively). In contrast, secondary glioblastomas rarely expressed CD133 antigen even after malignant progression following radiotherapy and chemotherapy.
Conclusions
The authors' results indicate that CD133-positive glioma stem cells could survive, change to a proliferative cancer stem cell phenotype, and cause recurrence in cases with de novo glioblastomas after radiotherapy and chemotherapy.

Abstract
BACKGROUND Central skull base lesions in the interpeduncular fossa and the upper clival regions can be challenging to access because of their location anterior to the brainstem. We have modified the anterior transpetrosal approach by combination with the extradural subtemporal route to increase the surgical corridor. METHODS Thirty-seven patients underwent surgical treatment via the anterior transpetrosal approach from 2002 to 2012. The combined surgical approach was primarily applied when the tumors arose from the upper clival portion and extended to the interpeduncular fossa. The combined approach was used in seven of these patients, comprising four patients with petroclival meningiomas, one patient with sphenoclival meningiomas, one patient with trigeminal schwannoma, and one patient with an epidermoid cyst extending from the interpeduncular fossa to the prepontine cistern. RESULTS The combined approach permitted excellent visualization of the interpeduncular fossa in addition to the upper clivus and the lateral aspect of the brain stem. Mobilization of the temporal lobe by the entire epidural dissection of the lateral wall of the cavernous sinus facilitates access via the subtemporal route. The transient symptom of the temporal lobe in the dominant site may be the only drawback for this combined approach, although it may disappear immediately after the surgery. CONCLUSION The present approach combines Dolenc's approach and Kawase's approach, providing a wide exposure to lesions of the interpeduncular fossa and the clivus.

Abstract
Introduction Granulomatosis with polyangiitis is characterized by systemic inflammation of medium and small blood vessels. Aortic involvement in granulomatosis with polyangiitis is extremely rare. As far as we know this is the first reported case of successful treatment in a patient with granulomatosis with polyangiitis complicated with aortic aneurysm rupture. Case presentation We describe a case of granulomatosis with polyangiitis in a 38-year-old Japanese man who developed an aortic aneurysm rupture 22 years after disease onset. The patient was operated on and a J-graft was inserted. He recovered uneventfully. Conclusion Recommendations in regard to, and consideration of, aortic involvement should be kept in mind in the long-term careful follow up of granulomatosis with polyangiitis.

Abstract
To classify the defects of the skull base, we present a new concept that is intuitive, simple to use, and consistent with subsequent reconstructive procedures. The centers of defects are determined in the anterior (I) or middle (II) skull base. The defects are classified as localized in the defect's center (Ia, IIa) or extended horizontally (Ib, IIb) or vertically (Ic, IIc) from the defect's center. Accompanying defects of the orbital contents and skin are indicated by "O" and "S," respectively. An algorithm for selecting subsequent reconstructive procedures was based on the classification. Using the new system, we retrospectively reclassified 90 skull base defects and examined how the defect classifications were related to the reconstructive flaps used and postoperative complications. All defects were reclassified with the new system without difficulty or omission. The mean correlation rate was high (88%) between the flaps indicated by the new classification and the flaps that had actually been used. The rate of postoperative complications tended to be higher with Ia, Ic, and IIb defects and combined defects. Our new classification concept can be used to classify defects and to help select flaps used for subsequent reconstructive procedures.

Abstract
The diagnosis and treatment of pituitary macroadenomas with entire hematoma fluid accumulation are problematic. Such lesions are often difficult to completely resect, and recurrence is not uncommon. We present five cases of pituitary macroadenomas entirely composed of hematoma fluid and investigated their histopathology to clarify the mechanism of the hematoma fluid accumulation. Five patients with pituitary adenoma and significant intra-tumor hematoma underwent transsphenoidal resection and were retrospectively reviewed for their clinical status, findings on magnetic resonance imaging (MRI), intraoperative findings, and histopathology. The specific surgical techniques used to address these cases were also reviewed. All patients were diagnosed with nonfunctioning pituitary adenomas by histopathological examination. MRI showed all tumors extended to the cavernous sinus. Histopathology showed tumor tissues were located between the thick granulation tissue and the pseudocapsule of the tumor. The thick granulation tissues were composed of collagenous layers, neovascular vessels, and necrotic red blood cells, indicating repeat hemorrhage from the granulation tissues. The boundary between adenoma and normal pituitary gland was identified during surgical removal in four patients and was not identified in the other patient who showed a recurrence 2 years later. Clinical and histopathological findings indicate hematoma fluid accumulation in the present cases is caused by repeat hemorrhage from the reactive granulation tissues and can be regarded as a chronic encapsulated expanding hematoma. In these cases, the boundary between adenoma and normal pituitary gland should be identified before puncturing the hematoma fluid to minimize the risk of tumor recurrence.

Abstract
OBJECT Surgical revascularization is considered an effective treatment for juvenile patients with moyamoya disease (MMD). Yet the long-term outcome in surgically treated patients still needs to be clarified. More than 30 years have passed since the authors' department started intensively treating pediatric patients with MMD using indirect anastomosis techniques. In this study the authors surveyed the current status of these patients. METHODS Activities of daily living (ADLs) were surveyed and present clinical status was assessed based on the modified Rankin scale (mRS). Cerebrovascular events subsequent to surgical treatment were also recorded. RESULTS Since 1979, 208 patients younger than 19 years of age with MMD were surgically treated and followed up for > 3 years. Data were available on 172 patients (83%), who had been followed up for a mean of 14.3 years (range 3-32 years). Activity of daily living outcomes were as follows: 138 patients (80.2%) had mRS scores of 0-2, 29 (16.9%) a score of 3, 1 (0.6%) a score of 4, 1 (0.6%) a score of 5, and 3 (1.7%) a score of 6. Cerebrovascular events occurred 8 or more years after surgery in 6 patients (3.4%), that is, 6 hemorrhages and 3 infarctions. The cumulative risk of late-onset stroke at 10, 20, and 30 years after surgical intervention was 0.8%, 6.3%, and 10.0%, respectively. CONCLUSIONS This long-term survey demonstrated that most surgically treated pediatric patients with MMD maintain good ADL outcomes. However, a significant number of new cerebrovascular events occurred more than 10 years after the initial surgery. Additional follow-up will help to identify which events may occur during the adult years of patients treated as children.

Abstract
OBJECTIVES/HYPOTHESIS Immunoglobulin G4 (IgG4)-related sclerosing sialadenitis is a recently recognized disease entity characterized by high serum IgG4 concentration and IgG4-producing plasma cell expansion in affected organs, which show fibrotic or sclerotic changes. However, little is known about the roles of CD4+ and CD8+ T cells or interleukin (IL)-17 in this disease. The purpose of this study was to evaluate the characteristics of CD4+ and CD8+ T cells and IL-17 in patients with IgG4-related sclerosing sialadenitis. STUDY DESIGN A retrospective clinical study at the Yamagata University School of Medicine. METHODS The patient group consisted of six males and four females with an average age of 57.9 years (range, 38 to 73 years). Subsets of T helper (Th)1, Th2, T cytotoxic type (Tc)1, and Tc2 cells from patients with IgG4-related sclerosing sialadenitis were examined by using intracellular cytokine flow cytometry. Expression of IL-17 in the patients' lesions was also investigated immunohistochemically. RESULTS Six patients with IgG4-related sclerosing sialadenitis with high ratios of IgG4/IgG and prominent infiltration of IgG4-positive plasmacytes in the involved salivary glands had systemic complications, including pancreatitis, retroperitoneal fibrosis, and/or inflammatory pseudotumor of the lung after the initial swelling of the salivary glands. Populations of Th1 and Tc1 cells were significantly greater in IgG4-related sclerosing sialadenitis than in the controls (P < .05), but Th2 and Tc2 cell populations were not significantly increased. Expression of IL-17 was observed in the lesions of affected patients. CONCLUSIONS Increases in Th1 and Tc1 cell populations and IL-17 expression might be involved in the mechanism of pathogenesis of IgG4-related sclerosing sialadenitis.

Abstract
Magnetite nanoclusters (MNCs) were aligned one-dimensionally in the hollow cavity of a lipid nanotube (LNT) as a peapod using a simple mixing method in an aqueous solution. The electrostatic interaction of the two materials was considerable enough to allow the preparation of a densely packed MNC-LNT peapod composite. The composite was formed at a pH 5.4-6.8, i.e., near the isoelectric point of the MNCs. At a pH 5.4-6.8, there was neither a strong attractive nor repulsive electrostatic interaction between the surface of the MNC and the LNT. The MNCs-capped LNT composites were formed at basic conditions (above a pH 7.8) in which the MNCs and the LNT pushed each other because of their opposite surface charges. The magnetic property measurement revealed that the 1D aligned MNCs in the peapod structure had a much higher coercivity (10.6 Oe) than the bulk randomized MNCs (5.8 Oe).

Abstract
The efficacy of combined high-dose steroid and PGE1 treatment initiated immediately after the onset of sudden deafness was analyzed with the outcome of 174 patients begun on treatment within 7 days of the onset of sudden deafness. Four potential prognostic factors (days from onset to treatment, age, initial hearing level, presence of vertigo) and hearing outcome were examined with a multiple logistic regression analysis. Days from onset to treatment and age significantly correlated with hearing improvement. The efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). In the examination of patients younger than 50 years, the efficacy of the treatment of patients begun on treatment within 3 days of the onset didn't differ significantly from that of patients on treatment 4-7 days after the onset. On the other hand, in the examination of patients aged 50 years and older, the efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). These results suggest that significant efficacy may be expected from the combined high-dose steroid + PGE1 treatment, if its use is started within 7 days of the onset of sudden deafness, and started within 3 days of the onset of sudden deafness in patients 50 years old and older.

Abstract
BACKGROUND Mucosal melanoma of the head and neck is rare and is associated with a poor prognoses because of locoregional failure and distant metastasis. The aim of our study was to review the characteristics of these patients in northern Japan and to analyze their outcomes. METHODS The medical records of 94 patients who had been provided initial treatment in 12 institutes from 1998 to 2007 were reviewed. RESULTS When the 5-year overall survival rates of patients were evaluated, we found that the survival rates of patients treated by chemotherapy were significantly lower than those of patients treated by surgery or radiation. The survival rates of the single-treatment modality, 2-modality, and ≥3-modality groups were 23.4%, 38.0%, and 33.6%, respectively. CONCLUSION Our results suggest that patients who underwent combined treatment had better prognoses. However, we found that chemotherapy had no additional survival benefits.

Abstract
We present a rare case of a large juvenile nasopharyngeal angiofibroma (JNA) in an 8-year-old boy. Preoperative imaging revealed that the tumor had widely extended to the sphenoid sinus, infratemporal fossa, and cavernous sinus. Following embolization of the feeding vessels, the tumor was successfully removed by a combination of an orbitozygomatic approach and Le Fort I osteotomy under frontolateral craniotomy. An endoscope assisted in the surgery. At 15 months follow-up, the patient was free of the disease with no facial palsy, scars, or malocclusion. JNA is a benign tumor that typically affects adolescent males and is rarely observed during prepuberty. Complete removal of JNA by surgery, the initial therapy, is generally required. However, as in the present case, a large JNA with wide extension requires extended surgery, and such a surgery is more invasive for prepubertal patients. Using an appropriate combination of surgical approaches, a large JNA developed during prepuberty can be safely removed with reduced morbidity.

Abstract
Objective: Seasonal grass pollinosis has recently become a major problem because many people suffer from this allergy. In this study, we evaluate the clinical effects of mometasone for seasonal grass pollinosis, the changes of chemical mediators in nasal lavage fluid, and their correlation with the clinical response. Method: Twenty patients were treated with mometasone from May to August 2009. To assess the clinical response, we focused on the changes of symptoms shown by the allergy diary of each patient. We also investigated the correlation of ECP, VEGF, and eotaxin levels in nasal lavage fluid with the severity of symptoms. Results: There was a significant reduction of the symptom score, medication score, and symptom medication score after administration of mometasone, and also ECP, VEGF, and eotaxin levels showed significant reduction in nasal lavage fluid. We found a significant correlation with VEGF and nasal symptoms. Conclusion: These results may allow us to speculate that mometasone furoate nasal spray is effective for the treatment of patients with seasonal grass pollinosis and also useful to improve QOL of these patients.

Abstract
The management of clival chordoma remains problematic. We present the case of a 48-year-old woman with clival chordoma who underwent multiple surgeries and radiation therapy, including gamma knife stereotactic radiosurgery (GK-SRS), during a 10-year clinical course. The tumor was initially removed by gross total resection via the trans-sphenoidal approach, followed by external linac radiation therapy. The tumor recurred at the clivus 5 years after the initial operation. After repeated trans-sphenoidal removal of recurrent tumors, she twice underwent GK-SRS for a tumor remnant adjacent to the brainstem. Although this part of the tumor was controlled by GK-SRS, there was further tumor extension toward the sphenoid and maxillary sinuses. Ultimately, lower cranial nerve dysfunction developed due to tumor extension into the lower part of the clivus and the patient died of respiratory failure. Autopsy revealed the tumor to extend from the lower clivus to the bilateral middle fossae. The lower part of the tumor extended to the nasal cavity and to the posterior wall of the pharynx, resulting in compression of the upper pharyngeal region. The tumor around the jugular foramen compressed the lower cranial nerves bilaterally. Tumor cells did not, however, invade the intradural space microscopically. Although chordoma is not biologically malignant, this tumor can show massive extension with destruction of bony structures and extracranial invasion of connective tissues. Therefore, the optimal treatment strategy is to remove the tumor mass as extensively as possible, including normal bony structures and connective tissues surrounding the tumor, using skull base surgical techniques.
