Total Hip Arthroplasty for Avascular Necrosis in a Patient With Hemophilia B.

Avascular necrosis (AVN) of the femoral head accounts for up to 10% of all total hip arthroplasties performed annually. Typically associated with intravascular coagulation, AVN is extremely rare in patients with bleeding disorders such as hemophilia B. In this report, we describe the therapeutic management of a 46-year-old male with hemophilia B, presenting with chronic left hip pain and AVN of the femoral head.

Successful carbon dioxide laser therapy for refractory anogenital lichen sclerosus.

Background: Lichen sclerosus is a chronic inflammatory dermatitis that often occurs in the anogenital area and presents a therapeutic challenge. Traditional medical management includes potent topical corticosteroids and is marked by variable results.

Objective: The objective was to describe the successful use of carbon dioxide laser ablation therapy in two women with refractory anogenital lichen sclerosus.

Avulsion and partial matricectomy with the carbon dioxide laser for pincer nail deformity.

Background: Pincer nail deformity is a common nail disorder that sometimes necessitates surgical intervention. A multitude of therapeutic modalities has been implemented to treat this condition.

Objective: To describe the use of the carbon dioxide laser in the successful treatment of pincer nail deformity.

Basosquamous carcinoma.

Background: Basosquamous carcinoma (BSC) is a rare cutaneous tumor that has been poorly described in the dermatologic literature. It has been depicted as an aggressive tumor with a high incidence of distant metastasis.

Objective: To examine the average extent of local tissue invasion and presence of distant metastases in cases of BSC compared with those of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).

Treatment of pearly penile papules with CO2 laser.

Background: Pearly penile papules are angiofibromas found on the corona and sulcus of the glans penis. While these represent a benign condition, psychological and cosmetic concerns often prompt patients to seek therapeutic removal of these lesions. Multiple therapeutic modalities have been reported; however, use of CO2 laser has proven to be the most effective to date.
