Erratum: Paracoccidioidomycosis of the Mouth: an Emerging Deep Mycosis

Oral fungal infections (mycoses) have come into particular prominence since the advent of infection with Human Immunodeficiency Virus (HIV), and recognition of the Acquired Immune Deficiency Syndrome (AIDS), as well as the phenomenal increase in world travel with increased exposure to infections endemic in the tropics. Paracoccidioidomycosis is a rare mycosis worldwide but common in Brazil and some other areas in Latin America. It can be life-threatening and can manifest with a spectrum of clinical presentations, including frequent oral lesions. This paper reviews the more recent information on Paracoccidioidomycosis, emphasizing those areas most relevant in dental science.

Effects on skeletal muscle amino acids and whole body nitrogen metabolism of total parenteral nutrition following laparoscopic cholecystectomy and given to healthy volunteers

In this descriptive study total parenteral nutrition (TPN) without glutamine was administered over 2 days to patients undergoing laparoscopic cholecystectomy (n = 8) and to volunteers (n = 8). Effects on muscle amino acids and nitrogen economy were studied. Muscle protein synthesis, determined by ribosome and polyribosome concentrations were measured in the patients. In both patients and volunteers the muscle amino acid patterns indicated muscle protein catabolism. Decreases in glutamine were seen in both groups (21.8 +/- 4.6% in patients and 17.5 +/- 5.4% in the volunteers). In both groups a negative nitrogen balance was seen (-4.1 +/- 1.2 gram and -10.3 +/- 2.4 gram respectively). The patients also showed decreased ribosome (by 13.7 +/- 4.5%) and polyribosome concentration (by 17.4 +/- 4.6%), indicating a decrease in muscle protein synthesis. No comparisons are made between the two groups since they are not comparable. However, it is concluded in these two descriptive studies, that during these conditions, TPN does not prevent muscle protein catabolism either during basal conditions or after a minor surgical trauma such as laparoscopic cholecystectomy.
