[Ruptured dissecting aneurysm of the vertebral artery concurrent with contralateral intracerebellar hemorrhage].

A case of a dissecting vertebral aneurysm concurrent with contralateral cerebellar hemorrhage is reported. A 69-year-old man was referred to our hospital for treatment of subarachnoid hemorrhage (SAH). On admission, CT scanning showed SAH and left cerebellar hematoma.

Delayed resolution of intracranial germinoma after radiotherapy: a preliminary study of the correlation between histology and magnetic resonance imaging.

A central nervous system germinoma is curable in most cases by radiotherapy, and most of the tumor mass disappears promptly after 20-30 doses. However, some germinomas take a longer period to vanish completely from magnetic resonance imaging (MRI) or computed tomography (CT) scans. In such cases, the tumor may contain components such as teratoma.

Metastatic carcinoma in a transposed ovary after radical hysterectomy for a stage 1B cervical adenosquamous cell carcinoma. Case report.

A 41-year-old multigravida woman presented with a cervical stage 1b adenosquamous cell carcinoma with metastasis in a transposed ovary. Twenty-four months following a radical hysterectomy for cervical cancer a CT scan revealed a mass measuring 7x6x4 cm in size lateral to the ascending colon. The pathological diagnosis showed the mass to be metastatic adenocarcinoma in the transposed ovary which was considered to be adenocarcinoma from the previous cervical adenosquamous cell carcinoma.

Primary leiomyosarcoma of the cervical spine causing spontaneous compression fracture: report of an autopsy case.

An extremely rare case of the primary leiomyosarcoma of the cervical spine presenting as a compression fracture is reported. A 69-year-old man complained of dysesthesia of both hands. A plain radiograph, computed tomography and magnetic resonance imaging of the cervical spine showed a compression fracture of the vertebral body at C7 without the formation of an obvious mass.

Superficial temporal artery dilatation in a patient with infectious temporal headache clinically mimicking temporal arteritis.

A 57-year-old woman noticed a pulsatile shooting headache in her right temporal region 3 days after extraction of a tooth from the right mandible. The following day, a localized headache over the right superficial temporal artery (STA), low grade fever, and jaw claudication appeared and progressed subacutely. Seven days after the onset, magnetic resonance imaging and angiography (MRI/MRA) disclosed inflammatory swelling of the right temporal muscle and dilatation of the right STA.

[L-dopa effective parkinsonism appeared after shunt revision of the aqueductal stenosis: report of two cases].

We present a two cases of parkinsonism that appeared after shunt revision in obstructive hydrocephalus patients. Case 1 was a 59-year-old man and case 2 was a 32-year-old woman. Parkinsonism appeared in both cases after 3 or 4 shunt revisions within a period of three months.

Effect of long-term atrial-demand ventricular pacing on cardiac sympathetic activity.

It has been shown that either dual-chamber or atrial pacing may be better than ventricular single-chamber pacing, but the long-term effect of dual-chamber pacing on cardiac sympathetic activity is unclear. The aim of this study was to assess the effect of long-term dual-chamber pacing on cardiac sympathetic activity, compared with atrial pacing and unpaced individuals. We studied 11 patients with dual-chamber pacemakers (Group D), nine with atrial single-chamber pacemakers (Group A) over the long term (mean 44 +/- 36 months) and 10 normal individuals without cardiac pacing.

Neuroimaging of a wooden foreign body retained for 5 months in the temporalis muscle following penetrating trauma with a chopstick--case report.

A 48-year-old female was stabbed by her husband with a chopstick made of wood in the left temporal region during a quarrel. She suffered laceration of the left temporal scalp. At initial examination, she concealed the assault with a chopstick.

Abnormal cortical processing of voluntary muscle relaxation in patients with focal hand dystonia studied by movement-related potentials.

In order to clarify the abnormality in cortical motor preparation for voluntary muscle relaxation of the hand in patients with focal hand dystonia, Bereitschaftspotentials (BPs) preceding voluntary muscle contraction and relaxation were recorded in eight patients (three with simple writer's cramp and five with dystonic writer's cramp), and were compared with those from 10 normal subjects. Voluntary muscle relaxation: after keeping the right wrist in an extended position for > 5 s, the subject let the hand drop by voluntarily terminating muscle contraction of the wrist extensor without any associated muscle contraction. Voluntary muscle contraction: the right wrist was flexed by voluntarily contracting the wrist flexor muscle.

[Serum protein fractions in patients with laryngeal cancer undergoing radiation therapy. Possibility as a prognostic factor].

The levels of 21 protein components of the sera of 45 patients with cancer of the larynx undergoing radiation therapy were determined by a single radial immunodiffusion method before and after radiation therapy. We examined the correlation between changes in serum protein fractions and the prognosis of the patients. The patients with cancer of the larynx were treated with external irradiation of 60Co gammer-rays.

The effect of HLA alleles on response to interferon therapy in patients with chronic hepatitis C.

Objective: To compare HLA alleles in the patients with chronic hepatitis C treated with interferon-alpha (IFN-alpha) between patients with response to IFN treatment and nonresponse.

Method: Sixty-seven Japanese patients with chronic hepatitis C were treated with daily intramuscular administration of IFN-alpha (6 million units) for 2 weeks followed by three times per week for 22 weeks. Viral loads of hepatitis virus C (HCV), HCV genotypes and HLA antigens were determined just before IFN-alpha treatment.

[Acute ventricular septal perforation in a patient with autoimmune hemolytic anemia].

A 71-year-old woman with autoimmune hemolytic anemia underwent an emergency endocardial patch repair for ventricular septal perforation after acute myocardial infarction. Use of washed red blood cells was effective in averting hemolytic crisis throughout perioperative period. In spite of improvement of her hemodynamics, liver dysfunction which had been present preoperatively deteriorated after the operation.

Remission induction by granulocyte colony-stimulating factor in hypoplastic acute myelogenous leukemia complicated by infection. A case report and review of the literature.

A patient with hypoplastic acute myelogenous leukemia (AML) who achieved remission with granulocyte colony-stimulating factor (G-CSF) alone is reported. The 59-year-old male patient received antibiotics and G-CSF but not any antileukemic drugs because of ongoing pneumonia. After 2-week administration of G-CSF, he achieved complete remission and his pneumonia improved.

[The significance of the cerebellar tonsillar herniation on the cause of sudden death of ruptured cerebral aneurysm].

We experienced a case with sudden unexpected death caused by rupture of an intracranial aneurysm, which was confirmed by autopsy. Depending on this case, we reported the significance of the cerebellar tonsillar herniation on the cause of sudden death of ruptured cerebral aneurysm. A 58-year-old man was admitted to us for treatment of subarachnoid hemorrhage (SAH).

[Perioperative management of intracranial hemorrhage related to hematological disease].

Six patients with hematological disease complicated by intracranial hemorrhage were surgically treated in the last 2 years. In this study, in order to clarify indication for operation and perioperative management, 6 cases were classified into 2 groups. The details of each group were as follows: Group 1 was defined by the fact that the underlying hematological disease had not yet been controlled.

Ex vivo culture of peripheral blood CD34+ cells: effects of hematopoietic growth factors on production of neutrophilic precursors.

A major potential application for ex vivo culture of hematopoietic progenitor cells is the treatment of cytopenia following high-dose chemotherapy and hematopoietic transplantation. We have previously postulated that infusion of a sufficient number of neutrophil postprogenitor cells generated by ex vivo culture of CD34+ cells may be able to abrogate neutropenia. In this article, we describe further development of an efficient stromal-free, cytokine-dependent, static culture system for generation of these cells.

Xanthogranulomatous pyelonephritis.

A 76-year-old woman presented with spiking fever and right back pain. Ultrasonography (US) revealed that her right kidney was enlarged. Computed tomography (CT) showed the parenchyma was replaced by non-enhancing masses but the overall kidney shape was maintained.

Neonatal alloimmune thrombocytopenia associated with anti-human platelet antigen-3a antibody.

A sister and brother with neonatal alloimmune thrombocytopenic purpura (NAITP) caused by maternal anti-human platelet antigen (HPA)-3a are reported. The children had transient severe thrombocytopenia in the newborn period, and were treated with intravenous gamma-globulin and platelet concentrates from random donors. Although the sister had intracranial hemorrhage on day 2 postnatally, the development of the child has been normal and no neurological sequelae have been observed.

[A surgical case of aortic valve stenosis associated with systemic lupus erythematosus].

A 46-year-old woman was hospitalized for aortic valve stenosis (AS) associated with systemic lupus erythematosus (SLE) on April 12, 1996. She had a syncopal episode six months before admission. She was found to have thrombocytopenia, and was diagnosed with SLE by further examination.

[Brain stem glioma presenting with contralateral sensory impairment of ascending nature].

A case of brain stem glioma, presenting with impairment of contralateral pain-temperature sense of ascending nature, is reported. A 38-year-old woman with documented neurofibromatosis type 1 (NF-1) was admitted to our hospital for treatment, complaining of diminished pain-temperature sense in the left lower extremity. On admission, the symptom was first evaluated to be due to cervical myelopathy although motor involvement was absent.
