Ovarian carcinoma metastatic to breast: a case report and review of the literature.

Breast metastasis from ovarian carcinoma is a rare event, with only 26 cases being previously reported in the English literature. The twenty-seventh such case is presented herein, and the literature on this topic is reviewed. Metastases to the breast from the ovary signal widespread metastases and generally herald a rapid deterioration and death. Although rare, it is important that metastatic cancer to the breast be differentiated from primary breast carcinoma as both the treatment and prognosis differ significantly.

Accuracy in clinical laboratories participating in regional quality control programs.

Few studies have assessed analytic bias (accuracy) in clinical chemistry laboratories. Using the data base of a large regional quality control program, we studied, during a six-year period, analytic bias of participant "all-methods" results, as well as selected commonly used individual methods, for calcium, cholesterol, glucose, potassium, and sodium. Analytic bias was assessed by comparison with "benchmark" measurements by United States Bureau of Standards definitive methods and/or United States Centers for Disease Control clinical reference methods. The all-methods bias at selected clinically relevant analyte levels was +0.1% at 10 mg/dL for calcium; -0.7% for cholesterol at 200 mg/dL; +4.5% for glucose at 120 mg/dL; +0.5% for potassium at 4 mmole/L; and 0% for sodium at 145 mmole/L. There was sufficient agreement between benchmark and participant all-methods results for these analytes to suggest that the all-methods results may be useful analytic bias benchmarks in future regional quality control programs that use similar lyophilized human serum pools.

Office photography for facial cosmetic surgery.

A photographic record of the appearance of the patient's face and neck preoperatively, and of the changes resulting from surgery is a most important aspect of facial cosmetic surgery. This report describes a practical, efficient system of photography performed in the surgeon's own office. The photographic equipment can be placed in a relatively small area at a total cost of well under $1000. The procedure described, when smoothly running can provide almost 99% efficacy in obtaining consistently good photographs with a minimum of effort and time spent by the surgeon and his office staff. The photographs are a precise, valuable record (medically and legally) of the patient's preoperative and postoperative appearances, and are important for the patient to see and for the surgeon to study. The patient is provided with a striking reminder of preoperative reality; the surgeon with insight into the progress of his surgical expertness.

Accuracy in interlaboratory quality control programs.

Interlaboratory quality control programs provide an important contribution to achieving and maintaining accuracy in clinical laboratories. The various strategies for providing accurate target values in the two principal types of interlaboratory programs are reviewed.
