Presented is the case of a man who had localized depigmentation after local injection of triamcinolone diacetate. Search of the literature indicates that this is a rare complication of such therapy. Localized depigmentation may have important cultural implications for dark-skinned patients. There is some experimental evidence that less-potent and shorter-acting steroid preparations have a lower likelihood for depigmenting side effects, and such agents may be more appropriate when injecting subcutaneous structures to prevent this complication.

The case of a patient with emphysematous cystitis who presented with complaints of lower abdominal pain, dysuria, and pneumaturia is presented. The presenting symptoms, differential diagnosis, and radiographic and cystoscopic appearances of emphysematous cystitis, a rare complication of lower urinary tract infection occurring almost exclusively in diabetics, are reviewed. Treatment consists of urinary drainage, prompt initiation of antibiotic therapy, and strict glucose control. The prognosis usually is excellent.
Most patients presenting to the Emergency Department with acute arrhythmias can be adequately treated with the available, conventional antiarrhythmics. Recent studies have taught us to use them with better understanding. In the future, several new antiarrhythmics look promising for use in the Emergency Department when given by the intravenous route; particularly, pirmenol, encainide, esmolol, amiodarone, sotalol, and magnesium. However, there have been few comparison studies between various antiarrhythmics, and experience must be gained for a full understanding of the benefits and risks of these agents.
A case of fracture of the base of the little finger metacarpal is presented. These unusual fractures are not easily detected on the routine three-view "hand-series." Physicians should be aware of the AP oblique (Norgaard, or "ball-catcher's") view, which is helpful in detecting these fractures.
