Physiologic maxillary antrostomy--update.

Physiologic antrostomy, as presented in this paper, is a procedure developed by the author using both old and new techniques. Indications and contraindications for the use of the physiologic maxillary antrostomy are listed. The osteoplastic flap (trapdoor) is used to enter the antrum. The nature of the lesions which can be handled through this approach are covered. The methods for removal of the lesions without removing the mucous membrane lining are given. The indications for removing this membrane are also presented. The methods are presented for the placing of the ventilation tube in the natural ostium. A step by step description of the technique used to perform this type of surgery is presented. Using this method, surgery that is done in or through the maxillary sinus is simplified and the severe sequelae of the Caldwell-Luc type of surgery are largely overcome.

Humans

Lead pica produced in rats.

Weanling rats eating a low calcium diet voluntarily ingested lead acetate solutions in much greater proportions than did iron-deficient or control weanlings. This increased ingestion occurred even with high concentrations of lead acetate which normal weanlings found extremely aversive. Chronic injections of lead acetate into weanlings did not change lead ingestion, indicating an absence of behavioral regulation of body lead levels. Female lead-injected weanlings did show a significant increase in calcium ingestion. Calcium deficiency may be one component of lead pica.
