BACKGROUND On an average 30-50% of patients who undergo incision and drainage (I and D) of anal abscess will develop recurrence or fistula formation. It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous. Th...

Two sulfur compounds have been identified in the anal gland secretions of captive-raised adults of the striped polecat (Ictonyx striatus), an African mustelid. 3-Ethyl-1,2-pentanedithiolane was observed in the secretions of an adult male and an adult female. 1,3-Pentanedithiol was observed in the male; this compound has not previously been reported from mustelid anal glands.

A perianal mass in a 15-year-old domestic shorthair cat with a history of a firm, painful swelling in the left ventrolateral perianal region was surgically excised and submitted for light microscopic evaluation. Histologically, this was a poorly demarcated, unencapsulated, multilobulated neoplasm that invaded surrounding perirectal skeletal muscle bundles. Lobules were composed of sheets and ac...

UNLABELLED An emerging Mycobacterium tuberculosis complex (MTC) pathogen, M. mungi, infects wild banded mongooses (Mungos mungo) in Northern Botswana, causing significant mortality. This MTC pathogen did not appear to be transmitted through a primary aerosol or oral route. We utilized histopathology, spoligotyping, mycobacterial interspersed repetitive units-variable number of tandem repeats (M...

Perianal fistula commonly occurs in an otherwise healthy patient, typically, middle-aged men. Most experts believe that it occurs as result of anal gland obstruction, secondary abscess formation and subsequent external decompression through one of several fairly predictable routes. The internal origin of the fistula usually begins from the middle of the anal canal at the dentate line. Fistulae ...

In search for biological sources of the long-chain fatty aldehydes (penta-, hexa-, and heptadecanal), which we recently identified as ligands for members of the mouse odorant receptor subfamily OR37, the headspace of secretions and excretions from mice was analyzed by gas chromatography and mass spectrometry. In urine, skin swabs, and saliva, these components were not detectable. However, in fe...
