The authors describe the method of cephalometric diagnosis known as "quadrilateral analysis", proposed by Di Paolo R.J.: this method offers an accurate assessment of skeletal dysplasia, particularly for--orthodontic surgery.
The purpose of this experiment was to study the early processing stages of encoding and recognition of slow movement in a short-term motor-memory paradigm. These stages were examined by determining whether Laabs' (1973) differential decay rates for location of movement and distance of movement could be replicated when the interfering activity was performed during the criterion and replication movements. 20 subjects performed a linear-positioning task in a 2 X 2 X 2 (count X movement type X retention interval) experimental design. 10 subjects in one condition counted backwards by 3s during the criterion and replication movements. There were no detrimental effects for location and distance-cue reproduction when attention was shared with counting backwards. Like Laabs' results, location of movement was maintained over the 15-sec. interval while distance of movement spontaneously changed. These results supported the notion that the early stages of encoding and recognition of cues for movement can occur unaffected by a secondary task.
To determine whether memory search for movements was serial or parallel, the search processes involved in a short-term motor-memory paradigm were investigated. A linear-positioning task was used to present a series of 1, 2, or 3 movements in a memory set. Upon completion of a memory set, subjects were presented with a search movement. The search movement was either the same length as one of the memory-set movements ("yes" response) or a different length ("no" response). Four subjects completed three consecutive days of testing. On Day 1 RT and movement length were practiced. On Day 2 the subjects were required to search a memory set of movements and respond in the yes condition by lifting the index finger of the left hand. This movement terminated a RT search clock. The same procedures were followed on Day 3, except that a no response was indicated by lifting the index finger. A 2 X 3 X 3 (response X memory set X RT trials) within-subjects analysis yielded nonsignificant main effects and interactions. The results were discussed in relation to verbal memory.

The Authors examine the international literature about the relationship between orthodontics and TMJ status. In five articles cited, the TMJ status who had received orthodontic treatment was compared with controls and no major differences was noted.
Hallermann-Streiff-Francois Syndrome, or oculomandibulodyscephaly is a rare congenital anomaly, characterized by bilateral congenital cataracts and bird-face. As the disease always involves oral troubles, that sometimes precede or predominate over other symptoms, the patient need oral examinations and life-long rehabilitation.

The AA. discuss the problem of morphology of cranial base in children with cleft lip and palate, using a cephalometric appraisal. They record the data from 28 patients with cleft and from 30 normal children; the linear dimensions from nasion to sella and sella to basion are significantly reduced in the cleft lip and palate group, while cranial base angulation doesn't differ between the cleft sample and the control group.
