Epidemiologic Investigation
A total of 28 patients met the case definition; none had more than one abscess. The 28 case-patients received the injections associated with their abscesses during a 2-month period (April 20-June 22, 1995). Case-patients ranged in age from 13.6 to 79.8 years (mean = 43.2); 23 (82.1%) were female.
All case-patients had been given a [...]
Benzalkonium chloride (ВС) is an unreliable disinfectant. A matched case-control study and environmental investigation were conducted to determine the cause of and risk factors for a cluster of postinjection abscesses at a private medical clinic where ВС was used as a disinfectant. Twenty-eight case-patients who had an abscess at the injection site were matched with [...]
Results
We mailed 1,030 questionnaires and received responses from 710 (70%) of 1,009 eligible subjects. We excluded 21 subjects who moved without leaving a forwarding address, died, or were no longer in practice. Respondents were predominantly white males with busy practices (Table 2). Respondents had experience with managed care, fee-for-service reimbursement (Table 3), capitation, utilization review, [...]

Our questionnaire included four scenarios in which a test or referral is indicated [...]
Parathyroid Cyst: An Uncommon Cause of a Palpable Neck Mass and Hypercalcemia
PARATHYROID CYSTS ARE rare lesions arising in the neck and anterior mediastinum. Goris reported the first case in 1905, and since then, fewer than 250 cases have been published in the literature. Parathyroid cysts constitute only 0.6% of all thyroid and parathyroid lesions, but [...]
KETOACIDOSIS is A RARE complication of diabetic pregnancies. It occurred at a rate of 1.73% in a recent series of pregnancies with preexisting, insulin-dependent diabetes. Ketoacidosis is an extremely rare complication of gestational diabetes, as well. In addition, ketoacidosis has been reported in two patients with previously undiagnosed diabetes. We report a case of early [...]
