ReIn more specific terms, the Oxford Dictionary of Hu- sources and logistics permitting, mentees should try to develop mentoring relationships with multiple man Resource Management (© Oxford University mentors in different capacities. In addition to primary Press, 2010) defines mentoring as “the process, mentors, namely the Pathology faculty to whom the whereby a senior employee takes an active role in developing a junior colleague.

As well as giving advice, the mentor might also prove useful in providing contacts that help the mentee to engage in the process of networking.” This definition seems to readily apply to Pathology training programs in which practicing Pathologists and Pathology educators facilitate in various ways, the favorable metamorphosis of students to Pathologists through the critical stage of residency. With the above perspective, it seems appropriate to reflect on the mentee side of the equation as applicable to Pathology mentoring. Once students transform to residents, they typically become units of a smaller, much more interconnected training group in which timed lectures and tailored laboratory sessions are no S J h g w a n , W y o m i n g a m e s P .

Secondary mentors would be visiting faculty or faculty at a collaborating institution with whom the mentees could interact periodically and primary mentors could facilitate such interactions. When feasible, mentees could also interact with tertiary mentors who would be members of organizations such as the American College of Veterinary Pathology, American Society of Investigative Pathology and Society of Toxicologic Pathology. Such interactions would typically be remote (electronic / telephonic) and should ensure that conflicts of interest are avoided. Annual and regional meetings could serve as venues of periodic follow-up on tertiary mentoring interactions. Through all these possibilities, mentees could prudently take it upon themselves to find the “intuitioninstruction equilibrium,” and assimilate and integrate as much as they can of the various styles and skill sets in line with their aspirations and long-term goals. I’ll now conclude my reflections and suggestions as a former mentee with the hope of transforming myself into a mentor. With a final note of gratitude to those who have mentored me in Pathology I wish all Pathology mentees-to-be the very best in finding productive “knowledge connections.” C o r m o r a n t J o s h E x e l l h t t p : / / p h o t o g r a p h y . n a t i o n a l g e o g r a p h i c . c o m “The capacity to blunder slightly is the real marvel of DNA.

The microscope lab is set up with slide cases, gross photos are displayed on a projector screen, and club members make themselves available to prospective students to answer questions both about the pathology field and veterinary school life in general. The club’s members take active roles in College research. Over the past two years, three members have participated in the College’s Summer Veterinary Scholar Research Program (supported both by an NIH T35 grant and the Morris Animal Foundation) and attended the Merck-Merial NIH National Veterinary Scholars Symposium to present their research. Dillon Muth’s project developed regulatory dendritic cells with the pregnancy estrogen Estriol. Gabrielle Pastenkos performed sequencing and phylogenetic analysis of three major surface antigens of Neorickettsia risticii. Bonnie Harrington’s project differentiated biologically high grade mast cell tumors from their biologically low grade counterparts based on molecular biology. Fourth year member Lauren Mattei received the OSU CVM 2010 Advances in Veterinary Medicine day basic research travel award for her poster, "Innate Immunity to Oral Salmonella Infection in Absence of IL-17." Club members attend the annual ACVP conference with financial assistance from the ACVP. At this year’s conference, Dillon Muth will be presenting a poster titled, “Synovial Cell Sarcoma in a Marmoset”. The club makes a yearly presentation at the College’s open house program. The microscope lab is set up with slide cases, gross photos are displayed on a projector screen, and club members make themselves available to prospective students to answer questions both about the pathology field and veterinary school life in general. The combination of outstanding pathology faculty, an excellent resident training program, and strong student interest facilitates exposure to a wide variety of practical pathology experiences for OSU students.

Signalment: 10 year old, female, naive, cynomolgus macaque (Macaca fascicularis). History: On routine external examination, a mass was palpated in the caudal abdomen. Examination of a fine needle aspirate from the mass was non-specific and contained erythrocytes, hemosiderin-filled macrophages, and rare neutrophils. The animal was euthanized and necropsied. Clinical pathology (hematology, coagulation, routine clinical chemistry) identified a slightly decreased hematocrit (31%). Necropsy: The urogenital tract and colon/rectum were consolidated into a mottled, firm, irregular, approximately 4 x 4 x 5 cm mass that contained many blood filled cysts. Gross appearance of endometriosis in a human. The rectum is adherent to the left uterosacral ligament and the back of the cervix with endometriosis.

Some of the cysts were filled with extravasated erythrocytes. V o l u m e 3 , I s s u e 1 Page 9 Case Report The case of the mass-Laden Macaque Microscopic Appearance……………. 200µm At higher magnification, the wall of the cysts was composed of ectopic endometrial tissue with epithelium, glands, and stroma. Histopathology: The outer surface of the uterus, ovary, broad ligament and colon were distorted and covered by many small coalescing cystic masses. The cysts were variably filled with erythrocytes, few neutrophils, macrophages and cellular debris and were lined by a single layer of well-differentiated glandular epithelium, morphologically consistent with endometrium. This epithelial layer was supported by spindleshaped endometrial stromal cells which merged into the adjoining smooth muscle or connective tissue. There were multiple interspersed areas of fibrosis expanded by chronic inflammation containing macrophages (some of them containing hemosiderin), lymphocytes and plasma cells. V o l u m e 3 , I s s u e 1 Case Report The case of the mass-Laden Macaque And the answer is……………. Microscopic diagnosis: Chronic endometriosis with adhesions Comments: Endometriosis is the ectopic growth of endometrial tissue, outside the uterus (Fanton et al., 1986). Endometriosis is a common disorder of sexually mature female macaques with a reported incidence of up to 30% in some colonies (Zondervan et al., 2004). Reported clinical signs in macaques with endometriosis are non-specific and include body weight loss, anorexia, constipation, decreased fertility and anemia. The masses in the abdominal and pelvic cavity can occasionally be palpated externally or by digital rectal examination. Grossly, endometriosis is often observed as mottled, tan, cystic masses in the pelvic and abdominal cavity over the surface of uterus, urinary bladder, distal colon and ovaries. Histologically, these masses are composed of ectopic endometrial glands and stroma with hemorrhage. This ectopic endometrial tissue undergoes cyclical changes in response to estrogen and progesterone, however the endometriotic lesions have been reported to have defective hormonal regulation (Sternfeld et al., 1988) Though an exact mechanism for the development of endometriosis is not known, it has been proposed that retrograde menstruation through the fallopian tubes causes the spread of endometrial tissue to the pelvic and peritoneal cavity (metastatic theory). Another hypothesis is that ectopic endometrium arises directly from the mesothelium of pelvis or abdomen (metaplastic theory). Risk factors for endometriosis reportedly include genetic predisposition, hysterectomy, whole body irradiation and exposure to toxins (Cline et al., 2008, Zondervan et al., 2004). Endometriosis is an important clinical condition of women and can cause infertility, pelvic pain and dysmenorrhea among other complications. Non human primates have been used as a model to investigate human endometriosis. References available on page 13.
