OBJECTIVES The aim of this study was to investigate: (i) the frequency and patterns of radiographic OA (ROA) in the thumb joints; and (ii) associations between thumb ROA and the clinical characteristics of thumb OA in older adults with hand pain or problems. METHODS Participants were 592 community-dwelling older adults with hand pain or hand problems who attended a research clinic. Hand X-ray...

triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...

We hypothesized that exposure of murine fetuses to environmental toxins, such as nitrofen, during early embryogenesis alters vasculogenesis. To address our hypothesis, we assessed protein levels of endothelial cell-selective angiogenic factors: angiopoietin (ANG)-1, vascular endothelial growth factor (VEGF), and mediator of VEGF signaling, VEGF receptor-2 [fetal liver kinase (Flk)-1], a transme...

A 31-yr-old female with congenital hypoplastic anemia (Diamond-Blackfan syndrome) whose long course terminated in acute myelogenous leukemia is described. In contrast to Fanconi anemia, malignant transformation rarely occurs in congenital hypoplastic anemia. This patient's diagnosis of congenital hypoplastic anemia is supported by her clinical course, absence of renal abnormalities, a negative ...

BACKGROUND AND PURPOSE Hypoplasia of the rostral third of the SSS is a well-known variant and constitutes the most frequent variation of the SSS after preferential drainage to one of the transverse sinuses. Our aim was to describe unilateral hypoplasia of the rostral end of the SSS. MATERIALS AND METHODS CTA performed in 100 consecutive patients studied for conditions other than dural sinus t...

osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.

In traumatic amputations in the upper extremities, replantation has been commonly attempted with high success rates. However, successful implies both maintenance of length and good functional outcomes restored hand. Since thumb accounts for 40% to 50% hand function, utmost priority is on salvage thumb. cases when not feasible, various efforts have made replace thumb, including pollicization ind...

Measurement of the pressure applied to the anterior region of the palate and incisor region of the mandible during thumb-sucking was carried out 3 female children. A polyethylene bag embedded with a high-sensitivity small pressure sensor was fixed on the ventral side of the thumb so that the baroreceptor could be interposed between the thumb and palate during thumb-sucking. The children were al...

introduction: dentin dysplasia is a rare autosomal dominant inheriting disturbance of dentin formation characterized by normal enamel formation, but atypical dentin with abnormal pulpal morphology. there are two major patterns: type i and type ii. amelogenesis imperfecta is an autosomal dominant. x-link inherent disease that is classified by clinical manifestation into hypoplastic, hypomature, ...

INTRODUCTION Congenital trigger thumb is an uncommon anomaly of children. Its management is controversial, ranging from observation to extensive surgical release. We report a case of delayed presentation of bilateral trigger thumb along with a brief review of past literature. CASE REPORT A six year old girl presented with fixed flexion deformity of interphalangeal joints of both thumbs and No...
