Human immunodeficiency virus activity in rib allografts.

Purpose: The use of bone allografts involves the risk of transmitting infectious agents from the donor to the recipient as shown by historical surveys. A study was therefore undertaken to test the hypothesis that human immunodeficiency virus (HIV) activity can still be present after the freezing and thawing of ribs taken from an acquired immune deficiency syndrome (AIDS) patient at autopsy.

Materials And Methods: Rib samples were harvested under sterile conditions and frozen at -80 degrees C.

Immediate function of temporomandibular joint after total resection and reconstruction.

Two patients with recurrent parotid gland carcinoma required subtotal petrosectomy and infratemporal fossa type C approach. To achieve en bloc resection, the ascending mandibular ramus and the entire temporomandibular joint, including the adjacent temporal bone, were removed. An original technique for immediate reconstruction of the infratemporal region, including the glenoid fossa and the ramus of the mandible, is described.

Microscopic tonsillectomy: a double-blind randomized trial.

Objective: To evaluate microsurgical bipolar cautery tonsillectomy (TEmic) by comparing it with traditional blunt dissection tonsillectomy (TEtrad).

Design: A double-blind prospective randomized trial with stratification in two age groups.

Patients: 200 consecutive patients undergoing tonsillectomy for tonsillar hypertrophy, or recurrent or chronic tonsillitis.

Comparison between short- and long-term insulin-like growth factor response to recombinant human growth hormone.

Eight growth-hormone-deficient children were treated with recombinant human GH (rhGH). Results of the short-term metabolic response to rhGH performed at the start of therapy during a 5-day introduction period and long-term results on growth were analyzed. We could not find any correlation between the effects on the short-term metabolic test and the growth response during long-term therapy, namely between the urea and insulin-like growth factor-I response during the short test and the increase in growth velocity.
