Apocrine Chromhidrosis.

Apocrine chromhidrosis is a rare diagnosis that occurs due to colored sweat being secreted from the apocrine glands, which are located in the axillae, anogenital skin, and areolae and over the skin of the trunk, face, and scalp. We present the case of a 65-year-old woman who presented with a sudden onset of pink sweating affecting mainly her axillae but also her pelvis, causing staining of clothing and bed sheets. There was nil to note on examination and histology with immunostaining demonstrated focally prominent yellow-brown lipofuscin granules in the cytoplasm of the apocrine secretory cells confirming the diagnosis. The disease can have a significant psychosocial impact, and treatment remains challenging. Our case is unique because the red and pink coloring of sweat is less common in cases of apocrine chromhidrosis, which is often in favor of darker colored sweat, and the distribution involved the inguinal canal, which is also less often seen.

Crohn's disease incidence evolution in North-western Greece is not associated with alteration of NOD2/CARD15 variants.

AIM: To assess the trends in the incidence of inflammatory bowel disease (IBD) over 23 years in the same area and to identify genetic factors related to incidence evolution. METHODS: Patients with IBD arising from North-western Greece were systematically recorded through the 1983-2005 period. Trends in disease incidence and genetic patterns related to CARD15 variants were documented and correlated. RESULTS: A total of 447 patients with IBD were recorded (23.5% Crohn's disease, 72.7% Ulcerative colitis and 3.8% indeterminate colitis). Mean annual incidence rates of CD and UC were 0.9/100,000 (95% CI 0.1-1.7) and 2.7/100,000 (95% CI 1.7-4.1) inhabitants, respectively. There was a statistically significant increase of CD incidence (P<0.01) during the study period, in contrast to the UC incidence. There were no statistical differences in CARD15 variants over the study period. CONCLUSION: The incidence of CD in North-western Greece has risen disproportionately to that of UC in the 21st century. This is not related to alterations of genetic background though.
