PROBLEM: Abstract: Pathologic studies were performed on two specimens of eyelid that had been treated with permanent eyeliner (tattooing with ferrous oxide), one specimen excised four days after injection of the pigment, and the other obtained 12 months later. Each patient had undergone an ectropion repair of the lower eyelid that provided the specimen. The specimen studied four days after injection revealed by light microscopy scattered pigment granules within the epidermis and fine granules and small aggregates dispersed within the dermis. No acute or chronic inflammatory cells were observed in relationship to the deposits. The specimen obtained 12 months after eyeliner injection was studied by both light and electron microscopy. No pigment particles were observed within the epidermis, but rather there were coarse clumps of granular material in the dermis. Apart from scattered mast cells, which occasionally contained fine granules, and apart from the macrophages which appeared to have ingested the pigment granules, no other acute and chronic inflammatory cells were found. Electron microscopy demonstrated that while most of the granular material had been phagocytosed by macrophages, occasional granules were found in small dispersions within the cytoplasm of mast cells and fibroblasts of the dermis. Minimal migration of pigment within macrophages occurred to locations around lymphatic channels and within the superficial orbicularis muscle connective tissue.

SOLUTION: Light and electron microscopic findings with permanent eyeliner.

PROBLEM: Abstract: Instability of the knee is frequently found in association with congenital leg-length discrepancy. We have studied six such patients clinically, radiologically and arthroscopically. Clinical signs of knee instability and significant radiological changes were present in all, and at arthroscopy the anterior cruciate ligament was completely absent in four patients and functionless in the other two. This deficiency appears to be a congenital condition which may predispose to meniscus injury or retropatellar pain; it may also lead to subluxation or dislocation of the knee during leg-lengthening procedures.

SOLUTION: Congenital aplasia of the cruciate ligaments. A report of six cases.

PROBLEM: Abstract: Although pelvic inflammatory disease is the most common serious infection among young women of reproductive age in the United States, no nationwide data are available on the patterns of antibiotic treatment of this disease. To examine these patterns we analyzed over 25 million antibiotic prescriptions for treatment of pelvic inflammatory disease from 1966 through 1983, using the National Disease and Therapeutic Index. Most patients received a single antibiotic on an outpatient basis. Overall, use of natural penicillins declined markedly, and use of aminopenicillins more than doubled. Cephalosporins emerged as the most frequently prescribed antibiotic for hospitalized patients. Nationwide surveillance of treatment patterns may help to identify areas needing improvement through continuing education.

SOLUTION:
Antibiotic treatment of pelvic inflammatory disease. Trends among private physicians in the United States, 1966 through 1983.
