Kvantitativno-kvalitativna svojstva dermatoglifa kod dečaka sa autizmom u ap Vojvodini

Abstract

Dermatoglyphics is a science that examines dermal patterns on volar side of both palms and soles. By using clinical dermatoglyphics we can diagnose more than 150 diseases with a probability of up to 99.99%. Research’s objective is to determine possible differences of Dermatoglyphic Characteristics of Digito-Palmar Complex (DPC) comparing autistic boys with healthy population. Experimental group was conducted of 32 boys who had autism, and were aged from 7 to 15 (average age 8.7 years old) while control group consisted of 32 healthy men from 30 to 50 years old (average age 38.4 years old). Within the digital scope of DPC we examined tree types of dermatoglyphic patterns on fingertips (arch, loop and whrol) as well as dermal ridge count on each finger separately (FRC – finger ridge count) and total dermal ridge count on all ten fingers (TRC – total ridge count). Within palmar DPC area we measured angles between triradius (atd, dat, adt, atb, btc, ctd) as well as dermal ridge count (RC- ridge count) between triradius a-b, b-c and c-d. Results. Autistic boys had significantly higher count of arches (8.44%) on fingertips of both hands when compared to control group examinees (4.22%), while at the same time they had lower count of loops (28.44%) compared with control group (32.35%). Higher count of arches was especially expressed on fourth and fifth finger of both hands. Beside this characteristic, autistic boys had lower TRC and ab-RC as well as wider atd-angle. Conclusion. Dermatoglyphic analysis can be helpful in process of diagnosing autism at early age only as an additional diagnostic procedures.

Dermatoglifika je nauka koja se bavi pročavanjem dermalnih šara (dermatoglifa) na volarnoj strani šaka i tabanima. Upotrebom kliničke dermatoglifike se može dijagnostikovati više od 150 oboljenja sa verovatnoćom do čak 99,99%. Cilj istraživanja je bio utvrđivanje moguće razlike u dermatoglifskim karakteristikama digito-palmarnog kompleksa (DPK) između autističnih dečaka i zdrave populacije. Eksperimentalnu grupu su činila 32 dečaka sa autizmom uzrasta 7-15 godina (prosečne starosti 8,7 godina), a kontrolnu grupu 32 zdrava muškarca uzrasta 30-50 godina (prosečne starosti 38,4 godina). U okviru digitalnog dela DPK ispitivane su tri vrste dermatoglifskih obrazaca na jagodicama prstiju (luk, petlja i kotur) kao i broj dermalnih grebena na svakom prstu posebno (FRC – finger ridge count) i ukupan broj dermalnih grebena na svih deset prstiju (TRC – total ridge count). Kod palmarnog dela DPK su mereni uglovi između triradijusa (atd, dat, adt, atb, btc, ctd) kao i broj dermalnih grebena (RC- ridge count) između triradijusa a-b, b-c i c-d. Rezultati. Dečaci sa autizmom su imali značajno veći broj lukova (8,44%) na jagodicama obe šake u odnosu na ispitanike kontrolne grupe (4,22%), dok su istovremeno imali manji broj petlji (28,44%) od kontrolne grupe (32,35%). Veći broj lukova je bio posebno izražen na četvrtom i petom prstu obe šake. Pored ove karakteristike dečaci sa autizmom su imali niži TRC i ab-RC kao i veći atd-ugao. Zaključak rada upućuje na činjenicu da dermatoglifska analiza može biti od koristi u procesu ranog dijagnostikovanja autizma kao jedna od pomoćnih dijagnostičkih procedura.
