pachydermodactyfy is a rare, benign mostly asymptomatic digital fibromatosis, characterized by swelling on the back and sides of proximal phalanges and (or) proximal interphaiangeal joints. it occurs predominantly in young males although a few women including a familial case were recently described. a history of repeated trauma is sometimes available, but the etiology remains unknown. we report...

A case of Dupuytren's contracture is described, in which, both clinically and histologically, knuckle pad lesions involved the extensor tendons. Surgical excision of the Dupuytren's tissue from the dorsal aspect of the proximal interphalangeal joints, freeing of the lateral extensor slips and posterior capsulotomy resulted in marked functional improvement.

Knuckle pads occur from benign thickening of the skin, principally the epidermis, and are occasionally seen in children. Despite the name, knuckle pads most commonly overlie the proximal interphalangeal joints. They must be differentiated from a variety of other cutaneous abnormalities. There is no consistently effective treatment, but knuckle pads have been reported to resolve spontaneously in...

BACKGROUND Cutaneous hyperpigmentation is an often overlooked clinical sign in megaloblastic anemia (MA) which has been sporadically reported in the literature. METHODS We describe the bone marrow (BM) changes and clinicolaboratory characteristics of 25 of 198 adult cases (>16 years) with cutaneous hyperpigmentation who underwent BM evaluation for cytopenia (s). RESULTS Twenty-one of 25 cas...

Biometric based personal recognition is an efficient method for identifying a person. Recently, hand based biometric has become popular due to its various advantages such as high verificat ion accuracy and high user acceptability. This paper proposes a hybrid model using an emerging hand based biometric trait known as Finger Back Knuckle Surface. This model is based on angular geometric analysi...

In this paper a new authentication system using Finger Back Knuckle Surface is examined. This paper is intended to propose an effectual method for personal authentication using Finger Back Knuckle Surface. This method take advantage of the less number of features extracted from the Finger Back Knuckle Surface and the Angular geometric analysis is done to mine the distinguishable feature informa...

Knuckle pads are a rare, frequently overlooked, thickening of the skin usually overlying the extensor surface of the proximal interphalangeal joints. They are well- circumscribed, benign lesions that generally do not require treatment. Idiopathic knuckle pads must be differentiated from similar appearing lesions or trauma-induced pseudo-knuckle pads. Knuckle pads have been observed in associati...

The relation of habitual knuckle cracking to osteoarthrosis with functional impairment of the hand has long been considered an old wives' tale without experimental support. The mechanical sequelae of knuckle cracking have been shown to produce the rapid release of energy in the form of sudden vibratory energy, much like the forces responsible for the destruction of hydraulic blades and ship pro...

There are different biometric modalities used to identify person which includes palmprint, face, fingerprint, iris and hand geometry. Apart from these biometric modalities, finger knuckle print also used as one of the cost effective biometric identifier. Finger knuckle print is defined by the back side of fingers. On the back side of fingers there are three joints named as Metacarpophalangeal (...

Biometric based personal authentication system has been receiving widespread interest in the area of research. In that, Identification of a person based on hand based biometrics has become a significant part in both research and real time application of personal authentication system. This paper proposes a new approach for personal authentication system based on Finger Back Knuckle Surface (FBK...
