Dermatomyositis in five Shetland sheepdogs in the United Kingdom.
Five cases of dermatomyositis in four Shetland sheepdog puppies and one adult bitch are described. The dogs all had well-defined patches of scaling, crusting and alopecia over the muzzle, periorbital skin and distal limbs, and the tail, perineum and pinnae were affected in some of them. The affected puppies were all sired by the same stud dog. The affected adult bitch was unrelated to the puppies. Three of the four dogs tested had high serum creatine kinase concentrations and electromyographic abnormalities were detected in three of the four dogs tested. The histological changes observed in the skin of four of the dogs strongly supported the diagnosis of dermatomyositis, and in the fifth dog they were compatible with this diagnosis. Two of the puppies were euthanised shortly after being diagnosed. In the other two puppies and the adult the disease remains stable and non-progressive 15 to 18 months after diagnosis. The sire of the four affected puppies has been used extensively because it was considered to be genetically clear of collie eye anomaly.

Double-blind, placebo controlled study of acetyl-l-carnitine in patients with Alzheimer's dementia.
A randomized, double-blind, placebo-controlled, parallel-group clinical trial was carried out to compare 24-week periods of treatment with 1 g acetyl-l-carnitine twice daily and placebo in the treatment of patients with dementia of the Alzheimer type. A total of 36 patients entered the trial, of whom 20 patients (7 active, 13 placebo) completed the full 24 weeks. Whilst several of the efficacy indices showed little change in either group during the trial, there was an apparent trend for more improvement in the acetyl-l-carnitine group in relation to the Names Learning Test and a computerized Digit Recall Test, both related to aspects of short-term memory. Similarly, there was a trend for reaction time in the computerized classification test to show less deterioration in the active treatment group. Changes within groups, and changes between groups, failed to reach statistical significance, at least partially because of the small number of patients available for analysis. Two indices of overall therapeutic benefit showed a trend for less deterioration in the active-treatment group than in the placebo group. Nausea and/or vomiting occurred in 5 patients in the acetyl-l-carnitine group. Laboratory tests revealed no signs of drug toxicity. The results suggest that acetyl-l-carnitine may have a beneficial effect on some clinical features of Alzheimer-type dementia, particularly those related to short-term memory.

Effect of maternal glucose load on fetal activity.
The effect of a MGL upon fetal activity has been studied in 39 normal and 54 high-risk pregnant patients between 30 and 42 weeks' gestation. The perinatal morbidity and mortality rates were significantly lower in the group showing an increase in fetal activity following a MGL. It is suggested that this may be useful for identifying the fetus at risk.
Early retransfer: a method of optimal bed utilization of NICU beds.
To facilitate increased utility of Neonatal Intensive Care Unit (NICU) beds, we adopted a policy of early discharge (ED) of infants less than 2000 g to the hospital of their birth after recovery from acute illness and when the infant was breathing room air and taking adequate oral feedings. An inservice teaching program at the primary hospitals preceded such policy. In a 24-month period, 446 infants were referred to the NICU. 111 of 446 died; 335 infants survived. 114 of 335 infants were less than 2000 g at birth; 42% (48 of 114) of them were discharged early to the hospital of their birth (ED); 58% were discharged late (LD) to their homes. 59.7% of the ED and 46.3% of the LD required assisted ventilation. Gestational age, birth weight, and final weight at discharge from hospitals were the same in both groups. None of the ED infants developed complications at the hospital of birth after retransfer. The length of NICU stay for LD was significantly higher 40 +/- 6 (p less than 0.001) than the ED; 20 +/- 2.2 days. In addition, a 15% increase in bed utilization was also noted because of ED. We conclude that ED of infants from the NICU 1) increases utilization of beds; 2) decreases the cost of health care; and 3) increases the participation of primary physicians.
Fetal heart rate responses to fetal movements.
A classification of fetal heart rate (FHR) responses to fetal movements is based on the study of 210 hours of antepartum cardiotocographic tracings in clinically normal pregnant patients between 30 and 42 weeks gestation. The physiological mechanism underlying the FHR responses to fetal movement are discussed.
