RESUMEN
From March to September 2001, 315 specimens from "nonrepeat" patients that were submitted for ova and parasite examination were stained using the Kinyoun modified acid-fast stain to detect the intestinal coccidians. Four patients (1.3%) were infected with coccidians, 2 with Cryptosporidium parvum and 2 with Cyclospora cayetanensis. No infections with Isospora belli were detected. In comparison, 15 patients (4.8%) had infections with one or more intestinal parasites detected by routine trichrome staining: 5 had Giardia lamblia; 2, Dientamoeba fragilis; 3, Strongyloides stercoralis; 1, Iodamoeba bütschlii; 3, Endolimax nana; 6, Blastocystis hominis; and 1, Entamoeba coli. Four patients were multiply infected. Coccidians made up 29% of the clinically significant parasitic infections. The coccidians were missed in all 4 cases because no special staining was ordered. Clinicians need to be reminded that additional tests should be ordered to fully evaluate patients with chronic diarrhea in which no diagnosis is found by routine testing.

Sin Nombre virus (SNV), an emerging pathogen in the United States, was identified in 1993. This hantavirus, a member of the Bunyaviridae family of RNA viruses, is transmitted by its reservoir host Peromyscus maniculatus, the deer mouse. Transmission is by inhalation of aerosolized feces, urine, or saliva from the infected mice. The illness that pursues, hantavirus pulmonary syndrome (HPS), is characterized initially by mild flu-like symptoms, followed by rapid progression to respiratory distress. There is no established therapeutic regimen and treatment is only supportive. Preventive methods include attempts to minimize contact with the rodents since elimination of the virus is not realistic.

Empyema is one of the potential complications of lower respiratory tract infections. Very rarely, in predisposed individuals, empyema can be caused by Trichomonas species, of which Trichomonas tenax appears to be the most common cause. Here, we present a case of trichomonal empyema in a 56-year-old man and review the available literature of this rare occurrence.
