Factors influencing the survival of patients with cancer of the prostate.
During the period 1969 through 1973, 777 new cases of cancer of the prostate in northern Alberta men were registered with the Alberta Cancer Registry. The overall survival rate after 5 years was 41.2%. As expected, the rates were higher for those aged less than 65 years than for those who were older at the time of diagnosis and higher for those without metastases than for those with metastases at that time. Urban residents had a higher survival rate than rural residents (45.3% v. 38.0%), and the survival ratio of the former, 1.31, was significant. Information on occupation, smoking and the interval between appearance of the first symptom and diagnosis was not always available. However, the differentials observed suggest that those in a professional occupation and nonsmokers live longer after the diagnosis of cancer of the prostate but that the interval before diagnosis does not affect the length of survival.

Genetic screening of newborn in Australia: results for 1980.
Since screening of newborn infants for phenylketonuria (PKU) by Guthrie bacterial inhibition assay was established in the 1960s, 2779 790 infants have been tested in Australia. Two hundred and forty cases of PKU (rate: 1/11 582) and six cases of the variant forms of malignant hyperphenylalaninaemia (MHPA) (rate: 1/463 298) have been detected. In 1980, 18 infants with PKU were detected. Screening for congenital hypothyroidism was carried out in six centres, and 40 new cases were detected in 1980.

Genetic screening of newborn in Australia: results for 1979.
Since screening of newborn infants for phenylketonuria (PKU) by Guthrie bacterial inhibition assay was established in the 1960s, 2 556 498 infants have been tested in Australia. Two hundred and twenty-two cases of PKU, and five cases of the variant forms of malignant hyperphenylalaninaemia (MHPA) have been found over this period, an incidence of 1/11 516 for PKU, and 1/511 300 for MHPA. In 1979, 18 infants with PKU and one with MHPA were detected. Screening for congenital hypothyroidism was carried out in four centres, and 28 new cases were detected in 1979 (an incidence of 1/5746).

Activities of hexokinase, phosphofructokinase, fructose bisphosphatase and 2-oxoglutarate dehydrogenase in muscle of normal subjects and very ill surgical patients.
1. The activities of hexokinase, phosphofructokinase, fructose bisphosphatase and 2-oxoglutarate dehydrogenase have been measured in the vastus lateralis and rectus abdominus muscle of normal human subjects and in very ill surgical patients. 2. The activities of these enzymes in the muscle of control subjects were similar to the pattern seen in the skeletal muscle of other mammals and lower vertebrates. 3. Fructose bisphosphatase and phosphofructokinase activities were significantly lower in the muscle of ill patients although the depression of the activity of fructose bisphosphatase was much greater than that of phosphofructokinase in both muscle types of ill patients. 4. The maximum rate of cycling in the fructose 6-phosphate--fructose, 1,6-diphosphate cycle may be altered in the ill. 5. This decreased cycling may have a direct influence on the sensitivity of glycolysis to regulators such as the adenine nucleotides and may reduce the ability to maintain body temperature. 6. Increased glycogen synthesis in these muscles may indicate that the role of fructose bisphosphatase is unlikely to be solely in glycogen resynthesis.

Recurrent thrombotic thrombocytopenic purpura after viral infection. Clinical and histologic simulation of chronic glomerulonephritis.
We describe a patient with recurrent thrombotic thrombocytopenic purpura (TTP) manifested solely by aphasia after influenza infection. The clinical diagnosis was not made during acute episodes, and during the intercurrent period the patient had features of chronic glomerular disease, including hypertension, proteinuria, RBC casts, and a nonspecific renal histological appearance. A final episode of aphasia, acute renal failure, and microangiopathic anemia and thrombocytopenia made the diagnosis of TTP apparent. Chronic glomerular disease may in rare instances be a manifestation of occult TTP or the sequel of a prior acute episode of this disorder.

Genetic screening of the newborn in Australia. Results for 1978.
Since screening of newborn infants for phenylketonuria (PKU) by Guthrie bacterial inhibition assay was established in the 1960s. 2 334 679 infants have been tested in Australia, and 208 cases of PKU detected (an incidence of 1/11 224). In 1978, 21 infants with PKU were detected. Screening for hypothyroidism was carried out in three States, and 29 cases of congenital hypothyroidism were detected in 1978 (an incidence of 1/5894).

Screening of cord blood low-density-lipoprotein cholesterol in the diagnosis of familial hypercholesterolaemia: a study of 2000 infants.
A prospective follow-up study of infants selected by cord blood total cholesterol (TC) and low-density-lipoprotein cholesterol (LDL-C) levels from 2000 consecutive live births was undertaken to reassess the role of cord blood screening in the diagnosis of familial hypercholesterolaemia (FH). Mean values for serum cholesterol were (mmol/l +/- S.D.): TC, 1.83 +/- 0.56; LDL-C, 0.90 +/- 0.49; HDL-C, 0.70 +/- 0.33; TG, 0.38 +/- 0.16. Seventy-three of 117 infants who had had a cord TC and/or LDL-C greater than 95th percentile, and 373 control group children (cord TC and/or LDL-C less than 95th percentile) were followed up at age 3--12 months. Six of the 117 were hypercholesterolaemic (HC), and one child had an HC parent: positive detection rate greater than or equal to 0.05%; false positive rate greater than or equal to 3.7%. Four control-group children were HC and had an HC parent; false negative rate greater than or equal to 1.1%. With the possible exception of detecting FH in a child with a known affected parent, cord blood screening appears to be unreliable for the diagnosis of FH.

Galactosaemia: case for neonatal screening illustrated by recent Australian experience.
The varied presentation and clinical features of classical galactosaemia are illustrated by the case histories of seven babies born in Western Australia since January, 1962, and of two babies born in South Australia in whom diagnosis was made as a result of adding galactosaemia to the Guthrie screening programme in October, 1974. All were shown to have a severe deficiency of galactose-1-phosphate uridyl transferase in their red blood cells. We compare our findings with those in 10 galactosaemic babies born in Victoria over a similar period, and show that in both groups these were two main modes of onset: acute and insidious. Jaundice and Escherichia coli infection were prominent in the 13 babies with an acute onset of galactosaemia, while poor weight gain, intermittent vomiting and cataracts were features of the five babies with an insidious onset. An enlarged liver was usually found in both groups. We discuss the various approaches to neonatal screening of galactosaemia in the light of experience in Massachusetts and South Australia. The use of cord blood can be expected to lead to diagnosis before babies with acute onset become ill, while the use of blood collected at five days for the Guthrie test avoids the collection of another routine sample for a relatively rare disorder. The result of red cell transferase assays of parents and siblings of our patients are discussed in relation to their implication for genetic counselling. The relevance of antenatal diagnosis to the prevention of possible intrauterine damage to an affected fetus is pointed out.

The effects of psychotropic drugs on exploratory and stereotyped behaviour of rats studied on a hole-board.
Exploratory and stereotyped behaviour of Male Wistar rats was studied on a hole-board. The two forms of behaviour were differentiated according to the pattern of hole-dipping activity. Increasing doses of dl-amphetamine stimulated both forms of behaviour with stereotyped behaviour becoming predominant particularly at the higher dose levels. At the highest dose of amphetamine used (16 mg/kg) a gradual transition from exploratory to stereotyped behaviour was observed with time. As the drug wore off this transition was reversed. Haloperitol at a dosage of 0.1 and 0.05 mg/kg blocked the response to a high dose of amphetamine whereas a lower dose (0.02 mg/kg) blocked the stereotyped response to amphetamine while some exploratory behaviour still took place. Apomorphine inhibited hole-dipping but at lower doses another form of exploratory behaviour was induced, this behaviour becoming stereotyped as the dose was increased. It is concluded that there is a close relationship between exploratory and stereotyped behaviours. Monoamine systems appear to play a significant role in the regulation of both forms of behaviour.

Recent time-trends of age-specific death rates for breast cancer: Quebec and other provinces, 1965 through 1974.
For the 10-year period 1965 through 1974 the age-specific death rates for cancer of the breast decreased among middle-aged women, especially at ages 40 to 49 years, in Quebec, the Maritimes and the Prairies but not in Ontario or British Columbia. In women under 35 years of age the mortality generally increased, while in women aged 60 to 64 years there was little change except in the Prairies, where the rate increased. It seems probable that the trends reflect changes in incidence rather than in case-fatality. Some, but not all, of the pattern could be explained by changes in fertility over the past 50 years.

An automated method for studying exploratory and stereotyped behaviour in rats.
A technique is described for studying exploratory as well as stereotyped behaviour in rats using an automated hole-board. Both visual and automated recordings can be employed using the technique. Hole dipping is monitored automatically using an infra-red detector system. Repetitive patterns of hole-dipping are used as parameters of stereotyped behaviour while the more random patterns of hole-dipping are used as parameters of exploration. There was a high significant correlation between the records of hole-dipping behaviour as recorded visually and automatically. There was also a high significant correlation between the measures of repetitiveness/randomness of hole-dipping behaviour from automatic and visual recordings. The pattern and levels of hole-dipping conformed with expectations both as regards changes with time and with increasing doses of dl-amphetamine.

A phase III study comparing the clinical utility of four regimens of 5-fluorouracil: a preliminary report.
A clinical trial involving 462 colon, rectum, and breast cancer patients randomized among four different dosage regimens of 5-FU (an intravenous loading course, a weekly intravenous schedule, a nontoxic schedule, and an oral schedule) has shown a significantly better response among colon-rectum cancer patients for the intravenous loading course. In addition, duration of response and time to progression are also significantly better. Overall survival is approaching significance for the colon rectum group (p value .082). In contrast, breast cancer patients show little difference between treatments. Toxicity is somewhat higher for the loading course.

Exercise studies in horses: 1. A simple telemetry system for recording excercise ECGs in horses.
A robust low cost portable radiotelemetry system is described for the horse and its method of operation and advantages briefly discussed. The equipment consisted of 2 electrodes forming a bipolar lead, a transmitter, a receiver and a writing device. The sitting, application and immobilising of the electrodes was a most important factor in obtaining good quality recordings. ECGs were recorded at all paces and also while jumping and the results proved satisfactory.
