Thiamylal serum concentration for refractory convulsive status epilepticus while associated decreased concentrations of concomitant antiepileptics: a case report.

Background: Treating refractory status epilepticus (RSE) remains a challenge. Thiamylal can be used as a second- or third-line treatment; however, its potential to induce cytochrome P450 (CYP) activity may reduce the concentration of antiepileptic drugs (AEDs) administered prior to thiamylal. This report details a case of RSE patient treated with thiamylal, with monitored concentrations of thiamylal and other AEDs.

Clinical evaluation of an authorized medical equipment based on high performance liquid chromatography for measurement of serum voriconazole concentration.

Background: Therapeutic drug monitoring for voriconazole is recommended for its optimum pharmacotherapy. Although the feedback of the measurement result of serum voriconazole concentration by outsourcing needs a certain time (days within a 1 week), there was no medical equipment for the measurement available in clinical practice. Recently, a medical equipment based on high performance liquid chromatography, named LM1010, has been developed and authorized for clinical use.

Personalized Nutritional Therapy Based on Blood Data Analysis for Malaise Patients.

As medical doctors, we routinely check patient blood chemistry and CBC data to diagnose disease. However, these data and methods of analysis are very rarely used to find pre-disease conditions or treat undiagnosed malaise. Masatoshi Kaneko Ph.

The prognostic value of positron emission tomography/computed tomography in rheumatoid arthritis patients with methotrexate-associated lymphoproliferative disorders.

Recently, methotrexate-associated lymphoproliferative disorders (MTX-LPDs) in rheumatoid arthritis (RA) have been found to commonly occur in association with iatrogenic immunodeficiency. Several factors have been reported to be related to the prognosis. We herein investigate the efficacy of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in predicting the prognosis of MTX-LPD.

Clinical characteristics of methotrexate-associated lymphoproliferative disorders: relationship between absolute lymphocyte count recovery and spontaneous regression.

Several reports have shown that patients with rheumatoid arthritis (RA) are at increased risk of developing lymphoproliferative disorders (LPD). Methotrexate (MTX) has been recognized as a major cause of LPD. Sometimes spontaneous regression (SR) occurs after withdrawal of MTX.

Characterization of patients with aggressive adult T-cell leukemia-lymphoma in Okinawa, Japan: a retrospective analysis of a large cohort.

Okinawa Prefecture, located in the subtropics, is an area of endemic adult T-cell leukemia-lymphoma (ATL) in Japan. We retrospectively analyzed 659 patients with aggressive ATL in seven institutions in Okinawa between 2002 and 2011. The median patient age was 68 years.

[The appearance of t(9;22)(q34;q11.2) in BJP-λ type multiple myeloma during maintenance therapy including lenalidomide].

A 61-year-old man, who was diagnosed with Bence-Jones protein (BJP)-λ type multiple myeloma, was treated with bortezomib. Although maintenance therapy including lenalidomide was continued, t(9;22)(q34;q11.2) was detected in the marrow cells by a cytogenetic study.

Prolactin concentrations during aripiprazole treatment in relation to sex, plasma drugs concentrations and genetic polymorphisms of dopamine D2 receptor and cytochrome P450 2D6 in Japanese patients with schizophrenia.

Aims: The authors investigated the correlation between prolactin concentrations during aripiprazole treatment and various factors, including age, sex, plasma concentrations of aripiprazole and its active metabolite, dehydroaripiprazole, and genetic polymorphisms of dopamine D2 receptor (DRD2) and cytochrome P450(CYP)2D6.

Methods: The subjects were 70 inpatients with schizophrenia (36 men and 34 women), receiving fixed doses of aripiprazole (24 mg in 45 cases and 12 mg in 25 cases) for periods of between 2 and 30 weeks. Prolactin concentrations were measured by chemiluminescence immunoassay.

Effects of the CYP2D6*10 allele on the steady-state plasma concentrations of aripiprazole and its active metabolite, dehydroaripiprazole, in Japanese patients with schizophrenia.

The CYP2D6*10(*10) allele that causes decreased CYP2D6 activity is present in Asians with a high frequency of approximately 50%. We studied the effects of the *10 allele on the steady-state plasma concentrations of aripiprazole and its active metabolite, dehydroaripiprazole. The subjects were 63 Japanese patients with schizophrenia who had only the wild-type or *10 alleles.

Epidemiology of hip fractures in Okinawa, Japan.

This study investigated the current incidence of hip fractures in Okinawa prefecture and compared the data with those obtained in our previous study, which was conducted using similar methods in 1987/1988. All patients, aged 50 years or older and residing in Okinawa, admitted to Okinawa hospitals in 2004 for a fresh hip fracture were identified from hospital registries. Details were obtained from the medical records and radiographs of all patients and classified according to fracture type (cervical or trochanteric), age, sex, and fracture location.

Evaluation of marked rise in fecal egg output after bithionol administration to horse and its application as a diagnostic marker for equine Anoplocephala perfoliata infection.

To establish a reliable diagnostic measure for equine Anoplocephala perfoliata infection, the impact of deworming was examined in 12 Thoroughbreds to which bithionol (5-10 mg/kg body weight) was administered and feces were examined by the modified Wisconsin method using sucrose solution. One day after the administration, cestode eggs were detected in previously fecal egg-negative 3 horses and increased in the other 9 horses. The optimum time for post-deworming egg detection was examined in following horses: 17 mares were administered bithionol and 10 mares were used as controls.

A genotype distribution of human papillomaviruses detected by polymerase chain reaction and direct sequencing analysis in a large sample of common warts in Japan.

There have been no large-scale epidemiological studies of human papillomavirus (HPV) genotype distribution of common warts in Japan. A total of 213 patients with common warts (104 males and 109 females) in Japan were studied to detect HPV genotype distribution by polymerase chain reaction (PCR) and direct sequencing analysis. The results were as follows: 94 HPV-1a (44.

Impulse response function based on multivariate AR model can differentiate focal hemisphere in temporal lobe epilepsy.

The purpose of this study is to propose and investigate a new approach for discriminating between focal and non-focal hemispheres in intractable temporal lobe epilepsy, based on applying multivariate time series analysis to the discharge-free background brain activity observed in nocturnal electrocorticogram (ECoG) time series. Five unilateral focal patients and one bilateral focal patient were studied. In order to detect the location of epileptic foci, linear multivariate autoregressive (MAR) models were fitted to the ECoG data; as a new approach for the purpose of summarizing these models in a single relevant parameter, the behavior of the corresponding impulse response functions was studied and described by an attenuation coefficient.

Sleep spindles in human prefrontal cortex: an electrocorticographic study.

To investigate the sleep spindle activity of the human prefrontal cortex (PFC), we simultaneously recorded whole nights of polysomnographic and electrocorticographic (ECoG) activities during the natural sleep of epileptic patients. Subjects were nine patients with intractable epilepsy who had subdural electrodes surgically attached to the orbital (seven cases), medial (three cases), or dorsolateral (two cases) PFC, and in one case to the frontal pole. To examine spindle frequencies, fast Fourier transformation (FFT) and auto-correlation analyses were performed on the PFC ECoG and Cz EEG data, primarily on epochs of stage 2 sleep.

Clinical and epidemiological observations of cutaneous tuberculosis in Larkana, Pakistan.

Background: Cutaneous tuberculosis is widespread in Pakistan but has not been fully documented. This study was conducted to determine the clinical pattern, nature and existence of the disease in Larkana, Sindh province, Pakistan.

Methods: We are reporting 153 cases of patients with cutaneous tuberculosis who visited our department from 1996 to 1999.

[Longitudinal study of procedural memory in patients with Alzheimer-type dementia].

We never forget how to ride a bicycle, and it is thought that procedural memories are retained for a long time. Recently, it was reported that patients with dementia of the Alzheimer type(DAT) could not only acquire, but also retain, long-lasting procedural memories. Previous group studies had shown procedural memory retention times of only 1 month in DAT patients, while amnesic patients and healthy people could retain such memories for 12 months.

Absence of sleep spindles in human medial and basal temporal lobes.

All-night recordings from subdural electrocorticographic (ECoG) electrodes on the human medial and basal temporal lobes were analysed to examine spindling activities during sleep. Subjects were three males and three females who were candidates for neurosurgical treatments of partial epilepsy. Subdural electrodes were attached to the medial and basal temporal lobe cortices, allowing ECoG and electroencephalogram from the scalp vertex (Cz EEG) to be recorded simultaneously during all night sleep.

Clinical utility and validation of the Japanese version of Memorial Delirium Assessment Scale in a psychogeriatric inpatient setting.

Delirium is a common mental disorder in the elderly. The Memorial Delirium Assessment Scale (MDAS) was developed in 1997 to assess delirium severity over time. The purpose of the current prospective study is to assess the clinical utility, diagnostic potential, reliability and validity of the Japanese version of MDAS in a psychogeriatric unit setting.

Inhibitory effects of Alpinia speciosa K. SCHUM on the porphyrin photooxidative reaction.

It is thought that the beta-carotene defense mechanism against photosensitivity involves the inhibition of singlet oxygen formation, a kind of active oxygen. When we screened chemical substances obtained from plants indigenous to Okinawa, known to have residents with the longest life span in Japan, we found that Alpinia speciosa K. SCHUM (Japanese name: gettou), which is used as a food preservative, has an activity similar to that of beta-carotene.

Suppression of gamma activity in the human medial temporal lobe by sevoflurane anesthesia.

We have reported the presence of continuous gamma (30-150 Hz) activity in the human medial temporal lobe (MTL). Since the MTL is involved in learning and memory, we speculated that MTL gamma activity is related to such higher brain functions. It is thus of interest to learn how this activity changes during different states of consciousness.
