A report on the occurrence of accessory triradii in the subdigital area, and carpal triradii on the palm in Polish and Czech populations
01 Jan 2000-
TL;DR: In this article, the occurrence of accessory triradii and car- pal triridii on human palms in two populations was analyzed and a very high symmetry was stated between the occurrences of forms C(Y) and c(X) on right and left palms.
Abstract: The study analyses the occurrence of accessory triradii and car- pal triradii on human palms in two populations. Accessory triradii were observed in Polish and Czech populations very rarely (triradius d' was most frequent). The occurrence of the abortive main line C(Y) was observed more often in the Polish population and it was a statistically significant difference. A very high symmetry was stated between the occurrence of forms C(Y) and c(X) on right and left palms. A higher frequency of occurrence was stated in the case of carpal triradius t in the Polish population and of triradius t' in the Czech population. However, the differences are not statistically significant.

TL;DR: The results of the study revealed that dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop periodontitis.
Abstract: Background: Periodontitis is a chronic inflammatory disease affecting the connective tissue attachment and supporting bone around the teeth. Over the years, the retrospective analysis of the possible etiological factors responsible for periodontal infections has magnified to its brink. The necessity lies in segregating the evidences and acknowledging their potential role in disease pathogenesis. Genetic predisposition might explain such an individual variability that can be predicted by using various cytogenetic markers. However, these studies are far more costly and complicated. The present study was conducted to study the role of palmar dermatoglyphics as a diagnostic tool for periodontal infections. Materials and methods: The present cross sectional study comprised of 120 subjects who were categorized as those suffering from chronic generalized periodontitis (n= 60), in whom variouspalmar patterns were evaluated as compared to healthy controls (n=60), to find a “dermatoglyphic marker,” if any. Results:A statistically significant higher percentage of ulnar loops (80.5%) was seen in CGP patients as compared to a majority of whorls (80.17%) in the healthy controls (p < 0.001). The percentage of presence of palmar accessory tri-radii was similar in both groups χ2= 0.963 (p= 0.326). Mean a-t-d angle variation was statistically significant in the CGP group as compared to the healthy group χ2= 83.796 (p= 0.000). Conclusion:The results of the study revealed that dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop periodontitis.

TL;DR: This book is indispensable for the dermatologist and for any pathologist dealing with dermatological material, and the provision of reasonably full and up-to-date lists of references following each chapter is the greatest merits.
Abstract: WALTER J. LEVER, M.D. Third edition. Pp. vii + 653 with 320 illustrations. London: Pitman Medical. Philadelphia: J. B. Myincott. I96i. C6. It seems almost presumptuous for a dermatologist to review the new edition of Lever's book, so used is one to its being an authoritative guide in the histopathology of the skin. Here is Lever in an up-to-date, more valuable form, preserving intact the virtues of the earlier editions. The general classification used by the author is under the headings of congenital, non-infectious vesicular and bullous diseases, non-infectious inflammatory diseases, drug eruptions, degenerative diseases, diseases caused by bacteria, fungi, protozoa and viruses, metabolic diseases, tumours and the lymphoma and myelosis group. It is, therefore, easy to follow and explore. In this third edition, seven years after the second, much has been rewritten. Emphasis is laid on the developing techniques of histochemistry and electron microscopy. Several newly recognized entities of great interest to dermatologists-e.g. sub-corneal pustulosis and kerato-acanthoma-have now been assimilated into the book. A few diseases previously recognized but not discussed by Lever have now been included, e.g. lethal midline granuloma of the face. There is, as before, an abundance of good black and white photographs, but the text is perhaps more important, providing a clear dissertation on the histological features of every feature under discussion, with brief notes on the clinical appearance; the attention paid to differential (histological) diagnosis is especially valuable. Unobtrusively the reader is given an account in which fact and theory, experimental and clinical findings are given their due share. The style is of consistent clarity. There are excellent introductory chapters on techniques, embryology and the histology of normal skin. The book is rounded off by a useful glossary and a good index. One of the greatest merits of this book is the provision of reasonably full and up-to-date lists of references following each chapter; lists which are not narrowly confined to American sources but which draw upon the dermatological Jiterature of the world. This book, the new edition no less than the old, is indispensable for the dermatologist and for any pathologist dealing with dermatological material.
