Bier spots are small, irregular, hypopigmented macules that are usually found on the arms and legs. The macules disappear when the limb is raised. Bier spots have been reported in association with a number of conditions but there is no consistent association to specific desease. Although they usually affect young adults, we report a case of Bier spots that began in childhood. As an asymptomatic...

In 1992 Thomas Bier presented a strikingly simple method to produce a huge number of simplicial (n− 2)-spheres on 2n vertices as deleted joins of a simplicial complex on n vertices with its combinatorial Alexander dual. Here we interpret his construction as giving the poset of all the intervals in a boolean algebra that “cut across an ideal.” Thus we arrive at a substantial generalization of Bi...

Compartment syndrome is caused by any condition which increases interstitial pressure within a muscle compartment to the extent that blood flow is compromised. It is seen classically after trauma to an extremity with crush injury, vascular damage or subsequent tight bandaging. Its sequelae may include irreversible neural and muscular damage secondary to the ischaemic insult. Previously describe...

Bier spots are asymptomatic, small, irregular, hypopigmented macules characterized by a normal histological appearance, which are usually found on the arms and legs of young adults. We describe the simultaneous presence of Bier spots in two siblings. This finding is unusual since, to the best of our knowledge, concurrent familial cases have never been reported in the literature.

A straightforward and efficient anesthetic approach for hand forearm surgery is intravenous regional anesthesia (IVRA), often known as the Bier Block. Dr. August developed this method in 1908, it offers total well a bloodless operating room. Historically, local has been contained surgical field created by using an upper arm tourniquet. Major issues following IVRA with tourniquet are uncommon, a...
