[Number agraphia].

One hundred and seventy-five aphasic patients (50 total, 50 mixed, 50 motor-amnesic and 25 sensory-amnesic aphasics) were tested for the writing to dictation of numbers with more than one digit. Twelve types of error were found. The percentages for the different types of error were determined for all subtypes of aphasic patients and for the total group of patients. In 98% of the aphasic subjects at least one or several types of error were ascertained. In all, 80.6% of the patients were unable to write correctly a number of three digits. Certain types of disturbances, such as macrographia, serial writing, perseveration and mirror writing, occurred more often when numbers were dictated than when words or letters were dictated. In the patients with sensory-amnesic aphasia these disturbances were found more often than in those with motor-amnesic aphasia. With respect to German-speaking patients, a particular type of error concerns the serial ordering of numbers with more than one digit (Stellenwertfehler). This type of error was found in 34.9% of our patients. Our results suggest standard examinations of aphasic patients should include the writing to dictation of numbers with more than one digit.

Quantitative studies on speech characteristics of aphasics. A statistical approach to vocabulary.

The paper presents a linguistic-statistical study of the vocabulary and word-frequency as well as of the variety and frequency distribution of the parts of speech. Ten aphasics were studied in comparison with 10 normal controls. A corpus of 2,500 words was collected in each subject by means of a standard-interview. A significant reduction of vocabulary was noted in aphasics, especially of rare words, the frequent ones becoming still more frequent. Vocabulary reduction unequally affected the various grammatical categories; whereas the proportion of "conceptual" words (noun, adjective, verb) was markedly reduced in aphasics, that of "operational" ones (pronoun, numeral, preposition, conjunction) was less affected.

Measurement of hertzian waves capture at body surface in patients with traumatic paraplegia.

Using an original method--the Biohertzmetry--the level of hertzian waves capture at body surface was measured in 20 patients with traumatic paraplegia. A statistically significant decrease of the hertzian waves capture level in the toes in comparison with the proximal area has been noted in 12 patients with complete spinal cord lesion. In patients presenting an open or cicatricial decubitus ulcer, at scar level, in the surrounding skin area with modified colour--and even in a contiguous few millimeters large skin strip normally coloured,--a marked decrease of the level of hertzian waves capture in comparison with the healthy skin ares situated off the decubitus ulcers has been pointed out. Thus, the method used permitted to reveal the alterations of the tissue trophicity--including those undetectable with the naked eye--and to make an estimation of the degree of mortification of the tissues and a delimitation of the reduced trophicity area.

Exogenous precipitating factors in stroke.

We studied in 300 stroke patients (100 carotid ischemic, 100 vertebrobasilar ischemic, and 100 hemorrhagic) the precipitating factors (PF) of stroke. Precipitating factors were observed in 63.7% of cases. Of the 407 PF found in the whole sample, 60% occurred 24 hours before stroke, and 40%-2-3 days before it. The most frequently met PF were: physical effort (32.3%), extreme temperature (29%), psychic trauma (23.3%), and head and body positions that may unfavourably influence cerebral circulation (23%). These PF were usually observed in associations. The differences regarding the PF incidence in the 3 stroke types were not statistically significant.
