The authors review the most recent literature on "dental phobia" which is responsible for discomfort and delays in prevention and treatment of odontoiatric disorders. Special attention is devoted to the multifactorial etiology and to diagnostic classification of these difficulties, as well as to the therapeutic possibilities available today.

The aim of the study was the investigation of the ability of L-acetylcarnitine (Acn; 1.5 g daily oral route for 1 month) to enhance some performances requiring a high level of attention and reflex velocity. The sample includes 17 healthy subjects, 8 males and 9 females, 22 to 27 years old; 10 of the subjects practice sports at agonistic level, while 7 have a sedentary life style. Reflexes have been measured, baseline and after 17 and 30 days of Acn administration, through a purposely constructed reflex-meter able to determine the latency (csec) of the reaction to an auditory stimulus. The ability as well as the time of learning was determined, before and after treatment, as the time and the number of errors to get out of the maze of a videogame (the test was also carried out by an untreated control group). Acn seems to induce an enhancement of reflex velocity, with complete annulment of the difference between the dominant and the opposite hand, as well as a significant reduction (3 to 4 times superior to controls) of both the errors and the time with the maze test.
The case reported concerns a 57-year-old man with a 35-year history of hidradenitis suppurativa lesions confined to his buttocks and recently complicated by a large, ulcerated, well-differentiated squamous cell carcinoma. Wide surgical excision and grafting, requiring temporary colostomy, were performed with no recurrence or metastasis during the following 12 months. The relevant literature is reviewed and discussed.
Human sperm were exposed in vitro to laser radiation. An increase in progressive sperm motility was associated with a faster rate of sperm ATP consumption. Computer-assisted analysis of sperm motility confirmed the positive effect of laser irradiation on velocity and linearity of sperm.

Polytene chromosomes of the salivary gland cells from Drosophila melanogaster were observed by means of scanning electron microscopy using mainly the cracking method. Band and interband regions were visible as transverse striped patterns consisting of multiple, side-by-side fibres. Band regions seemed much more compact than interband ones. In the cross section of the entire chromosome, about 1,100 chromatid fibres could be counted. Intranuclear fine filaments could be recognized surrounding the polytene chromosomes each of whose diameters were almost the same (160--200 A). Field emission scanning electron micrographs showed the unit chromatid fibres clearly in very high magnification.
