Diarrhea is a frequent and potentially severe complication of kidney transplantation. We describe here, in a cross-sectional study, the epidemiological and microbiological characteristics of acute and persistent diarrhea in 52 inpatients with kidney and kidney-pancreas transplant in a hospital in Buenos Aires, 42 (80.8%) of whom had received a kidney and 10 (19.2%) a kidney-pancreas transplant. Diarrhea was the reason of admission of 34 cases (65.4%). ⋯ Seven patients (14.6%) persisted with diarrhea at the fifth day of admission. At hospital discharge all cases had complete resolution of symptoms and one third persisted with kidney failure. Information provided in this study can be useful as a starting point for improving preventive, diagnostic and therapeutic measures in these patients.

In recent years the incidence of melanoma in elderly patients has increased with an unfavorable oncologic outcome due not only to immune deterioration but also to greater aggressiveness of the tumor. The aim of this study was to evaluate the behavior of cutaneous melanoma in relation to age. A consecutive series of cases with melanoma operated in a reference center in the period 2001-2013 was included. ⋯ There was no difference between groups regarding nodal involvement. With a mean follow up of 45 (6-98) months throughout the series, recurrence of disease was higher in group 2 (26% vs. 17%, p: 0.03), but the specific mortality showed no significant difference (9.5% vs. 5.3%, p: 0.12). In conclusion, cutaneous melanoma in patients over 65 years is more aggressive with higher rates of local recurrence and distant metastases.
