[Papillary glioneuronal tumor with highly degenerative pseudopapillary structure accompanied by specific abortive glial cells: a case report].

Recently, unusual examples of tumors of the mixed glioneuronal type have been reported, including the papillary glioneuronal tumor (PGNT). A 23-year-old woman with a 2-3 months history of headache and insomnia presented with a tumor. Neuroimaging showed a right temporal lobe cystic tumor with a mural nodule enhanced by contrast medium.

Delorme's procedure for rectal prolapse: clinical and physiological analysis.

Purpose: Clinical and physiological results of Delorme's procedure were assessed retrospectively in patients undergoing this procedure for rectal prolapse.

Methods: A consecutive series of 31 patients (7 males, 24 females; age, 14-93, mean 70 years) with full-thickness, rectal prolapse were treated by Delorme's procedure between 1994 and 2002. Median follow-up was 39 (range, 6-96) months.

A case of giant expanding cephalhematoma: does the administration of blood coagulation factor XIII reverse symptoms?

Background: The mechanism of continuous massive hemorrhage into the subperiosteal space in children without coagulation defects is unknown. We report a case of giant expanding cephalhematoma reversed by the administration of blood coagulation factor XIII concentrate.

Method: The patient was an 8-year-old boy with a history of minor head trauma who developed a giant expanding cephalhematoma with intraorbital extension.

Anal endosonography in the diagnosis and management of perianal endometriosis: report of a case.

We report a rare case of perianal endometriosis, diagnosed in a 39-year-old woman who presented with a several-day history of a painful mass in the perineum. Perianal examination showed redness and swelling in the right anterior direction. A soft tumor was palpated, but there was no evidence of an episiotomy scar, or of fistula orifices.

Objective: To evaluate the diagnostic accuracy of magnetic resonance imaging for assessment of the endolymphatic sac and vestibular aqueduct.

Study Design: Imaging and histological study of the cadaver.

Methods: Five cadavers were studied by a 1.

Progenitor cells from dental follicle are able to form cementum matrix in vivo.

To address the molecular mechanisms of cementogenesis, we have isolated dental follicle cells and examined them to see if they contain cementoblast progenitors. Dental follicle tissue was dissected from the root surface of bovine tooth germ and cells were released by digestion with bacterial collagenase. The released cells were maintained as a bovine dental follicle cells (BDFC).

Intracranial cerebrospinal fluid measurement studies in suspected idiopathic normal pressure hydrocephalus, secondary normal pressure hydrocephalus, and brain atrophy.

Objective: To investigate intracranial cerebrospinal fluid (CSF) distribution in patients with a clinical diagnosis of idiopathic normal pressure hydrocephalus (INPH).

Methods: 24 patients with a clinical diagnosis of INPH were studied. Control groups comprised 17 patients with secondary normal pressure hydrocephalus (SNPH), 21 patients with brain atrophy, and 18 healthy volunteers.

Effect of Lactobacillus casei on a novel murine model of abdominal sepsis.

Background: Lactobacilli are one of the probiotics and there is strong evidence for the efficacy of lactobacilli administration as a nonspecific immunostimulant in increasing host defense mechanisms. The present study tested the hypothesis that heat-killed Lactobacillus casei (LC9018) has a protective activity against fecal peritonitis.

Methods: Cecal ligation and tip resection (CLTR) induced fecal peritonitis was developed as a novel mouse model of abdominal sepsis, and the effects of LC9018 pretreatment on survival after CLTR, of the peritoneal exudate cells before or after CLTR and of bacterial growth in the peritoneal cavity after CLTR were investigated.

Distinctive pleomorphic xanthoastrocytoma-like tumor with exclusive abortive or aberrant neuronal differentiation and repeated recurrence--case report.

A 9-year-old girl with a 1-month history of generalized seizure presented with a distinctive tumor resembling pleomorphic xanthoastrocytoma. Neuroimagings showed a right frontotemporal lobe tumor. Histological examination of the resected tumor indicated similarity to pleomorphic xanthoastrocytoma without staining for glial fibrillary acidic protein.

Dehiscence of the bony roof of the superior semicircular canal in the middle cranial fossa.

Spontaneous dehiscence of the superior semicircular canal (SSC) in the middle cranial fossa is rare and may cause clinical problems. This dehiscence was investigated in cadaveric and dried temporal bone specimens. One cadaveric specimen showed a spontaneous defect: the dehiscence was a symmetrical, elongated ellipse with smooth margins.

Nervous branch passing through an accessory canal in the sphenozygomatic suture: the temporal branch of the zygomatic nerve.

A nervous branch which passes through a small canal in the sphenozygomatic suture is sometimes observed during dissection. To examine the origin, course and distribution of this nervous branch, 42 head halves of 21 Japanese cadavers (11 males, 10 females) and 142 head halves of 71 human dry skulls were used. The branch was observed in seven sides (16.

Histological findings after placement of a self-expanding stent in rectal carcinoma with complete obstruction--case report.

Patients with acute obstruction due to colorectal carcinomas frequently require emergency surgery. However, such emergency procedures are associated with various complications, a high mortality rate and a poor prognosis. If the obstruction could be immediately relieved, the patient could later undergo an elective operation with a much better prognosis.

Fast inversion recovery magnetic resonance imaging with the real reconstruction method: a diagnostic tool for cerebral gliomas.

The fast inversion recovery (IR) technique was evaluated for the localization of gliomas. Fast IR imaging with real reconstruction and T1-weighted spin echo (SE) imaging before and after contrast administration were performed in 20 patients with gliomas. The tumor-to-white matter contrast ratio (TWCR), tumor-to-gray matter contrast ratio (TGCR), tumor-to-white matter contrast-to-noise ratio (TWCNR), and tumor-to-gray matter contrast-to-noise ratio (TGCNR) were calculated and compared.

Distance from acoustic neuroma to fundus and a postoperative facial palsy.

Objective/hypothesis: Generally, patients with small acoustic neuroma have less facial palsy after its removal. The middle cranial fossa approach is mainly applied to the small acoustic neuroma and tumor size does not influence the prognosis of facial palsy. The internal auditory canal cannot be fully opened in the middle cranial fossa approach, and the facial nerve is tightly attached in the fundus.

Electronystagmographic findings in patients with cerebral degenerative disease.

Cerebral degenerative diseases produce a variety of abnormal neuro-otological findings on electronystamography (ENG). To assess their diagnostic value and determine which manifestations are helpful in making a diagnosis, ENG findings from 72 cases of confirmed cerebral degenerative disease were analyzed. We observed a high incidence of saccadic pursuit and upward ocular dysmetria, which is likely to be useful in diagnosing cerebral degenerative disease.

Cross-sectional shapes of the internal auditory canal in patients with acoustic neuromas.

Cross-sectional images of the internal auditory canal (IAC) were investigated in 23 patients with acoustic neuroma in order to clarify the widening of the IAC. The area of the IAC and the ratio of areas (neuroma side:normal side) were calculated. The shape of the IAC was fitted by an ellipse to obtain the length of the axes and the direction of the long axis.

Synergistic effect of CGS16949A and 5-fluorouracil on a human breast cancer cell line.

The effects of the aromatase inhibitor, CGS16949A, and the fluoropyrimidine, 5-fluorouracil (5-FU), on cell cycle distribution and growth were studied using FACS analysis and MTT assay in the human breast cancer cell line, SK-BR-3. CGS16949A induced an increase in the G0-G1 fraction on SK-BR-3 cells, and the growth inhibition rate of the combination of both (65.7 +/- 3.

Intracranial cerebrospinal fluid distribution and its postoperative changes in normal pressure hydrocephalus.

Background: This study was conducted to investigate the usefulness of intracranial cerebrospinal fluid (CSF) volume measurement using MR-based methods in the management of patients with normal pressure hydrocephalus (NPH).

Methods: The study group comprised 19 patients with NPH who showed a favorable outcome after ventricular shunting, 15 normal volunteers (NV), and 15 patients with cerebrovascular disease (CVD). A 3D-fast asymmetric spin echo MR imaging sequence and the region-growing method were used to extract the CSF space from MR images.
