Parasagittal solitary fibrous tumor resembling hemangiopericytoma.

Solitary fibrous tumor (SFT) is a rare mesenchymal tumor in the central nervous system, and the clinical behavior of this tumor is similar to that of meningioma. We report the case of a Japanese woman with parasagittal SFT that resembled hemangiopericytoma (HPC). Histological examination revealed that the tumor was highly cellular, with cells containing oval- or spindle-shaped nuclei arranged in sheets or a pattern-less growth mode.

[Clinical features of patients with brain metastasis from testicular germ cell tumor].

We retrospectively reviewed 190 patients with germ cell tumors of testis or extragonadal origin who were treated in our hospital between 1980 and 2007. Five (2.6%) of them had brain metastasis.

Focal hand dystonia cured by removal of clinoid meningioma-case report-.

A 40-year-old Asian female presented with an unusual case of focal hand dystonia caused by contralateral clinoid meningioma. Magnetic resonance imaging showed that the tumor compressed the caudate nucleus, lentiform nucleus, cerebral peduncle, internal capsule, and a large portion of the white matter surrounding the basal ganglia. The tumor was gross totally removed via a frontotemporal approach with zygomatic osteotomy, resulting in cure of the focal hand dystonia.

Evaluation of postoperative status after clipping surgery in patients with cerebral aneurysm on 3-dimensional-CT angiography with elimination of clips.

Background And Purpose: the use of 3-dimensional computed tomography angiography (3D-CTA) for clipped aneurysms is limited. Usefulness of 3D-CTA with elimination of bone and clips was evaluated in patients with clipped cerebral aneurysms.

Methods: forty-three clipped cerebral aneurysms were included.

Retrospective comparison of mobilization methods for autologous stem cell transplantation in multiple myeloma.

The combination of cyclophosphamide and granulocyte-colony stimulating factor (G-CSF) has widely been used to mobilize hematopoietic stem cells (HSCs) for autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Recently, however, alternative approaches such as G-CSF alone or etoposide followed by G-CSF have been investigated. We, therefore, retrospectively analyzed the effects of these mobilization methods on collection yield and disease outcome in ASCT for MM.

Detection of changes in cerebrospinal fluid space in idiopathic normal pressure hydrocephalus using voxel-based morphometry.

Introduction: We attempted to detect alterations in the cerebrospinal fluid (CSF) space in patients with idiopathic normal pressure hydrocephalus (iNPH) using voxel-based morphometry (VBM).

Methods: We obtained sagittal volume images of the entire head by three-dimensional T1-weighted magnetic resonance imaging and compared the regional distribution of CSF in 12 patients with iNPH, 14 patients with Alzheimer's disease (AD), and 17 healthy individuals using VBM with automatically extracted CSF objects.

Results: VBM demonstrated significant widening at the lateral ventricles and Sylvian fissures and narrowing of the CSF space at the high convexity/midline areas in iNPH patients, compared to the AD patients and healthy controls (p < 0.

Subcortical intracerebral hemorrhage caused by mucormycosis in a patient with a history of bone-marrow transplantation.

We report on a rare case of a patient with rhinocerebral mucormycosis that presented as intracerebral hemorrhage (ICH). A 54-year-old man who was immunosuppressed had ophthalmoplegia. Four days later, ICH developed in his left frontal lobe.

Non-Born-Oppenheimer electronic and nuclear wavepacket dynamics.

A practical quantum theory for unifying electronic and nuclear dynamics, which were separated by the Born-Oppenheimer approximation, is proposed. The theory consists of two processes. Nonadiabatic (quantum) electron wavepacket dynamics on branching (non-Born-Oppenheimer) nuclear paths are first constructed.

[Adenomatoid tumor of the testis with testicular pain: a case report].

A 30-year-old man who complained of sudden right scrotal pain visited our clinic. Physical examination revealed a palpable mass with tenderness on his right testis. An emergent operation was performed for acute scrotum.

Effects of low-power laser irradiation on the threshold of electrically induced paroxysmal discharge in rabbit hippocampus CA1.

In acute experiments using adult rabbits, we measured the paroxysmal discharge threshold (PADT) elicited by stimulation to the apical dendritic layer of the hippocampal CA1 region before and after low-power laser irradiation. Nd:YVO(4) laser irradiation (wavelength: 532 nm) was introduced into the same region as the stimulation site. The average PADT was 247 +/- 13 microA (n = 18) before laser irradiation, while after 5-min laser irradiation with 50, 75, and 100 mW, PADT was 333 +/- 40 (n = 4), 353 +/- 33 (n = 4) and 367 +/- 27 microA (n = 6), respectively.

Is urethritis accompanied by seminal vesiculitis?

Objective: To determine whether urethritis is accompanied by seminal vesiculitis using transrectal ultrasound (TRUS) imaging.

Methods: Fifty-six male patients (mean age 31.6 8.

Skull base chordomas: efficacy of surgery followed by carbon ion radiotherapy.

Background: Skull base chordomas are challenging to treat because of their invasive nature, critical location, and aggressive recurrence. We report the effectiveness of combined radical skull base surgery with carbon ion radiotherapy for treating skull base chordomas.

Methods: Between November 1996 and August 2007, 32 patients (12 males and 20 females; mean age at initial presentation 41.

Three-dimensional bone-free computed tomographic angiography of aneurysms near the skull base using a new bone-removal application.

Purpose: Bone elimination is needed for computed tomography angiography (CTA) because bone structures obscure aneurysms located at the skull base. The purpose of our study was to evaluate the efficacy of three-dimensional (3D)-CTA using an application for bone elimination.

Materials And Methods: A total of 27 patients with 32 angiographically confirmed aneurysms near the skull base were investigated.

Incidence and risk factors of early bacterial infections after unrelated cord blood transplantation.

Incidence and characteristics of early bacterial infection within 100 days after unrelated cord blood transplantation (UCBT) were assessed for 664 pediatric and 1208 adult recipients in Japan. Cumulative incidence of early bacterial infection at day 100 post-UCBT was 11% (95% confidence interval [CI], 8%-13%) for children and 21% (CI, 19%-24%) for adults (P < .0001).

[Condyloma acuminatum].

Condyloma acuminatum is a sexually transmitted disease caused by human papillomavirus infection, especially HPV DNA types 6 and 11. Its appearance is distinctively papillary and it can be diagnosed by careful observation of its particular appearance. The treatment for condyloma acuminatum is generally classified into surgical and medical therapies.

Genetic profiles of fluoroquinolone-resistant Escherichia coli isolates obtained from patients with cystitis: phylogeny, virulence factors, PAIusp subtypes, and mutation patterns.

The low virulence of quinolone- and fluoroquinolone-resistant Escherichia coli strains is known, although the reasons for this remain unclear. We surveyed the mutation patterns of quinolone resistance determining regions (QRDRs), phylogenetic distribution, prevalence of 18 urovirulence genes, and PAIusp subtypes in 89 fluoroquinolone-resistant E. coli (FQREC) isolates obtained from patients with cystitis and compared them with those of their fluoroquinolone-susceptible counterparts (FQSEC).

[A long-term survival case of far-advanced colon cancer with Virchow's lymph node and lung metastasis that responded to multidisciplinary therapy].

The patient was a 73-year-old male. Under a diagnosis of advanced cecal colon cancer with metastasis to Virchow's and paraaortic lymph nodes and lungs, a laparoscopic-assisted ileocecal resection with D2 lymph node dissection was performed. Histological examination of the resected specimens revealed moderately-differentiated adenocarcinoma which had invaded the terminal ileum.

Hematopoietic stem cell transplantation for core binding factor acute myeloid leukemia: t(8;21) and inv(16) represent different clinical outcomes.

We analyzed 338 adult patients with acute myeloid leukemia (AML) with t(8;21) and inv(16) undergoing stem cell transplantation (SCT) who were registered in the Japan Society for Hematopoietic Cell Transplantation database. At 3 years, overall survival (OS) of patients with t(8;21) and inv(16) was 50% and 72%, respectively (P= .002).

Disease-specific analyses of unrelated cord blood transplantation compared with unrelated bone marrow transplantation in adult patients with acute leukemia.

We made a disease-specific comparison of unrelated cord blood (CB) recipients and human leukocyte antigen allele-matched unrelated bone marrow (BM) recipients among 484 patients with acute myeloid leukemia (AML; 173 CB and 311 BM) and 336 patients with acute lymphoblastic leukemia (ALL; 114 CB and 222 BM) who received myeloablative transplantations. In multivariate analyses, among AML cases, lower overall survival (hazard ratio [HR]=1.5; 95% confidence interval [CI], 1.

Pharyngeal Neisseria gonorrhoeae detection in oral-throat wash specimens of male patients with urethritis.

Detection of Neisseria gonorrhoeae and Chlamydia trachomatis in the pharynx has been highlighted in the prevention of the unexpected spread of sexually transmitted diseases. We tried to clarify the detection rate of Neisseria gonorrhoeae in the pharynx and the clinical relevance of oral-throat wash specimens to detect the organism in heterosexual men with gonococcal and nongonococcal urethritis. In our cohort of 79 male patients with urethritis, oral throat wash specimens were collected after they had gargled with normal saline for approximately 30 to 60 s.
