In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive). A survey of dairy goat farms in and around Pretoria carried out by means of a questio...

A population survey of 258 unrelated white British subjects showed a polymorphism for the 4-oxidation of debrisoquine. "Extensive metabolisers" (EM) and "poor metabolisers" (PM) are recognisable, 8.9% of the population being PM. Nine pedigrees ascertained through PM probands show that the PM phenotype is an autosomal Mendelian recessive character. The EM phenotype is dominant and the degree of ...

Extensive limb swelling (ELS) has been reported after vaccination with a limited number of vaccine types. We sought to describe vaccine types involved in and the clinical characteristics of ELS cases reported to the Vaccine Adverse Event Reporting System (VAERS). A case of ELS was defined as any report of edema extending at least to the elbow or knee of a vaccinated extremity. Four hundred nine...

PURPOSE To determine whether maintenance therapy with carboplatin and etoposide improves progression-free and overall survival in patients with extensive stage small cell lung cancer, compared to the standard four to six cycles of cisplatin and etoposide. METHODS Forty-two patient records (25 males and 17 females) were retrospectively reviewed in a single community practice. All patients were...

The objective of this retrospective study was to investigate prognostic factors associated with survival of patients with extensive stage small cell lung cancer (ES-SCLC). Included were 200 patients admitted to the Liberation Army General Hospital with a diagnosis of ES-SCLC. The demographics of patients, disease characteristics, pre-treatment biochemical parameters and therapeutic plan were as...

The article in this issue of ONCOLOGY by Kelsey et al differs very little from a recent publication on the issue of early Hodgkin lymphoma (HL) therapy from radiation oncologists.[1] These have been matched by editorials that question the role of radiation therapy in early HL, especially in nonbulky favorable presentations.[2-7] The argument that extensive radiation fields and doses have both b...

Medulloblastoma with extensive nodularity is a rare subtype of the most common malignant childhood brain tumor and has been associated with more favorable prognosis. The authors report the case of a 10-month-old girl with a posterior fossa tumor of excessive nodularity with decreased diffusivity on diffusion-weighted magnetic resonance imaging sequences and robust grape-like postgadolinium cont...

AIM To study the kinetic characteristics of lansoprazole in healthy Chinese subjects in relation to CYP2C19 genotype status for the individualized dose regimen of lansoprazole. METHODS Nine homozygous extensive metabolizers (homo EMs) and 9 poor metabolizers (PMs) were recruited for the study from a total of 70 healthy Chinese volunteers, whose CYP2C19 genotype status was determined by the PC...

Background: Recently, several papers have assessed land use consequences of biofuel expansion. In the absence of empirical evidence, these papers assigned subjective values to extensive margin (productivity of new croplands over productivity of existing croplands). Methods: This paper fills the gap in this area and provides a new data set which estimates land productivity at 0.5° × 0.5° (longit...

This study was conducted to investigate the effect of the reduced function allele CYP2D6*10, which can be the cause of an intermediate metabolizer (IM), on tolterodine pharmacokinetics. Tolterodine is mainly metabolized to an active 5-hydroxymethyl metabolite (5-HM) by CYP2D6, and 5-HM is also metabolized by CYP2D6. Asian and white healthy volunteers (n = 108) received once daily multiple doses...
