Post-operative computed tomography (CT) has been described as a technique for diagnosing incomplete resection or recurrence of cerebral neoplasms in humans. The characteristics of immediate postoperative CT images in dogs with intracranial pathology are unknown. This report describes findings from preoperative, immediate post-operative, and 4 week to 9 month follow-up CT examinations in two dogs with histologically-confirmed cerebral meningiomas. In images of one dog after surgery there was mild contrast enhancement of the tissue surrounding the surgical site. This enhancement had resolved in later images and was probably the result of surgically induced trauma. In post operative images of the other dog there was significant hyperattenuation of the tissues around the surgical site. In post contrast images there was increased enhancement that was evident in later images. These findings, although not supported by necropsy, probably indicate incomplete excision of the tumor.

Design of flattening filters for the fast-neutron beam at TAMVEC by use of decrement lines.

Isodose distributions in a tissue-equivalent phantom produced by fast neutrons from 50-MeV deuterons incident on a thick beryllium target exhibit strong forward peaking, particularly for large fields. The design by use of decrement lines and the construction of polyethylene filters used to "flatten" those distributions are discussed and the results are illustrated. Also, the compromises of central-axis attenuation versus effective filter width and of off-axis peaking versus depth of "flattening" are discussed.

The impact of income redistribution on fertility in Canada.

This paper speculates on the role of income redistribution as a means of raising fertility in Canada. It is argued that if the relationship between income and fertility is non-linear at the household level, then changes in the income distribution in a society have important consequences for changes in aggregate fertility. In order to test this hypothesis, a simple fertility model is estimated using micro-data collected in the 1981 Canadian Census. The relationship between income and fertility is found to be nonlinear with properties that indicate that transfers of income from "rich" to "poor" households will likely further depress the overall level of fertility in Canada.

Household structure and poverty.

"This paper proposes a method for controlling for compositional factors in the measurement of poverty. The method is based on the notion of 'direct standardisation', used extensively in the field of demography.... With this class of standardised measures, it [is] possible to examine underlying differences in poverty while controlling for compositional factors known to be correlated with the incidence and intensity of poverty. The method is illustrated by examining the relationship between household structure and poverty in seven European countries: France, Germany, Italy, Luxembourg, Netherlands, Poland and Great Britain. The data are centered around 1985 and form part of the Luxembourg Income Study." (SUMMARY IN FRE AND ITA)

Entry to lone parenthood: an analysis of marital dissolution in Great Britain.

"This paper examines some...socio-economic determinants of lone parenthood in Great Britain, in an attempt to understand further the reasons behind the rapid growth in lone parenthood. Since divorce and separation are the major 'causes' of lone parenthood, this paper focuses on the determinants of marital dissolution among women with dependent children. The empirical analysis is guided by hypotheses suggested by the 'economic theory of marriage'. Hazard regression equations are estimated with data collected in the 1980 Women and Employment Survey...." (SUMMARY IN FRE AND ITA)

Manipulation under epidural anesthesia with corticosteroid injection: two case reports.

OBJECTIVE: To discuss the combined use of selective epidural steroid injection (ESI) and spinal manipulative therapy (SMT) in treating recalcitrant lumbar radiculopathy. CLINICAL FEATURES: In a first case, a patient suffered from numbness and pain in an S1 dermatome distribution 6 months after undergoing lumbar discectomy. Clinical correlation with advanced imaging led to the diagnosis of L5 intervertebral disc (IVD) syndrome with peridural scar formation. In a second case, a patient suffered from low-back and right-leg pain of 9 months' duration. Various forms of conservative treatment were not effective. A diagnosis of L4 IVD syndrome with radiculopathy was made. INTERVENTION AND OUTCOME: The first patient received conventional treatments, including physical therapy, SMT, fluoroscopically guided ESI and oral medications, with consistent but short-lived response. A team consisting of an anesthesiologist (dedicated spinal injectionist) and chiropractor performed manipulation under epidural anesthesia (MUEA) with corticosteroid injection. Follow-up at 60 days showed marked improvement in visual analogue scale, pain drawing and Oswestry pain and disability index. The second patient received all of the same conventional care except ESI before the combined procedure. The patient underwent MUEA, followed up with eight sessions of stretching and manipulation over the ensuing 3 wk. At 45 days after the combined procedure, the patient had a negative SLR (previously positive at 70 degrees), no leg pain and a marked reduction in back pain. CONCLUSION: This article discusses an integrated procedure that combines two standard treatments that may act synergistically. Our positive results are consistent with other reports, both published and anecdotal. The technique of MUEA warrants further investigation by the health care industry.
