Cluster headache. The sweating pattern during spontaneous attacks.

Sweating in the forehead, on the eyelids, in the face and on the trunk was measured with the Evaporimeter during 31 spontaneous cluster headache attacks of varying severity in 18 patients. The evaporimeter measures evaporative water loss (sweating + transepidermal water loss) rapidly and accurately as g/m2/h. The patients themselves acted as controls. Sweating was also estimated in 25 healthy individuals at a temperature of 27 +/- 1 degree C, and a mean relative humidity of 19%. During eight severe attacks, sweating in the medial part of the forehead on the symptomatic side was invariably increased. In moderate attacks the increment was less pronounced and in the inter-cycle period, no definite increase was found. The cause of increased sweating during cluster headache attacks remains enigmatic.

Familial amyotrophic lateral sclerosis. Report of a family with predominant upper limb pareses and late onset.

Familial occurrence of neuromuscular disease similar to sporadic amyotrophic lateral sclerosis has been reported from several countries. A Norwegian family with muscular wasting in men and women of three generations is described. The propositus and his father's sister were examined, as well as a second cousin of the propositus. The disease was characterized by late onset, predominantly upper limb peripheral pareses, and "pyramidal" signs in the lower extremities. Although peripheral neuromuscular affection in the lower limbs tended to be subclinical, chonchotome biopsies from the tibialis anterior muscle showed neurogenic atrophy in all three cases.

Computer simulation of circumnutations--behaviour under different g's and comparison with experiment.

The influence of different g-forces on helical growth movements--circumnutation--of sunflower seedlings is treated. Predictions from a model, describing the movements as geotropic overshoot movements, are given. Results from tests of the assumptions are given. These results as well as results in the literature do not contradict the model. The need for more precise centrifuge tests under otherwise free fall conditions is emphasized.

Dental caries and periodontitis in persons with Down syndrome.

In a central institution for persons with mental retardation, the dental status in 30 adult patients with Down syndrome was compared with that in a carefully selected group of gender- and age-matched mentally retarded patients. This investigation showed an increased frequency of periodontitis in the population with Down syndrome. The caries rate, however, did not differ demonstrably between the groups. Edentulism was more frequent in patients with Down syndrome than in controls, and this fact may substantiate the observation of increased frequency of periodontitis. Caries seems to be less prevalent in institutionalized patients with mental retardation than in the population at large.
