A 7-year-old intact female Shih-Tzu with chylothorax was presented. Percutaneous popliteal computed tomographic lymphangiography was performed to evaluate the thoracic duct and seek any potential cause of chylothorax. Despite two attempts, visualization of the thoracic duct failed and perianal subcutaneous computed tomographic lymphangiography with injection of iodinated, nonionic water-soluble contrast medium (0.6 ml/kg) was performed. A single branch of intact thoracic duct and dilated and tortuous lymphatics were detected. It was diagnosed as idiopathic chylothorax. Perianal subcutaneous lymphangiography is considered a less-invasive, easy and reliable method to visualize lymphatics in patients with chylothorax.

Phthirus pubis usually infests the pubis, groin, buttocks and perianal region. It can sometimes infest the thighs, abdomen, chest, axillae and beard. Eyelashes and eyebrows may be involved in children. The involvement of the scalp is very rare. We describe a case of P. pubis infestation located exclusively on the scalp in an adult woman. Neither lice/nits nor skin lesions were observed elsewhere, including eyebrows, eyelashes, axillae, pubis, buttocks and perianal region (the patient was hairless in the axillae and pubis). A review of the literature is enclosed.

Gnotobiotic piglets (n = 10) were hand-reared in conventional germ-free facilities. Piglet body temperatures were measured with rectal and non-contact infrared thermometry (NIFT) on the lower eyelid, auricular center and margin, parietal regions, axilla, central abdomen and dorsum, and the perianal region. Body temperature measurements at central abdomen, cranial dorsum, and perianal regions had NIFT values which had a significant linear relationship (p<0.0001) with rectal thermometry. The predicted equations of between-subject formulas were calculated as follows: rectal temperature, 28.07489+0.30372${\times}$central abdominal surface temperature; rectal temperature, 34.02799+0.15197${\times}$central dorsum surface temperature; and rectal temperature, 33.87937+0.15676${\times}$perianal temperature. These results suggested that NIFT could serve as a valid alternative to rectal thermometry in a portable germ-free facility without disturbing experimental animals. The development of a NIFT body temperature evaluation that does not require animal restraint is clinically advantageous, particularly in gnotobiotic piglets, and would be significantly less stressful for experimental procedures in germ-free facilities.

Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.

Extramammary Paget's disease (EMPD) is a rare, slow-growing intraepithelial malignancy that mainly involves the genital region, including the vulva, penis, scrotum, perianal, and periurethral areas. Although several treatment options exist, wide local excision with a safe margin is considered the treatment of choice. After resection of the lesion, it is often challenging to reconstruct the defect because defects in the perineal region require adequate volume for protection and are susceptible to infections, which is a particularly significant risk for large defects. We report a case of perivulvar EMPD that was reconstructed with three-directional local flaps after wide excision of the tumor. We covered the defect sequentially using the following 3 flaps: a gracilis myocutaneous flap from the left thigh, a bipedicled V-Y advancement flap from the lower abdomen, and an internal pudendal artery perforator-based island flap from the right buttock. To the best of our knowledge, this report is the first to describe a three-directional approach to extensive perivulvar reconstruction.

Hepatoid gland tumors in dogs usually occur in the perianal region, but arise occasionally from other areas such as the tail, back, and thigh. This report describes two cases of ectopic hepatoid gland adenomas in dogs. The tumors have been observed in the lumbar area of the back and in the axillary region, respectively. The cytological and histopathological features were consistent with hepatoid gland adenoma. Although ectopic hepatoid gland tumors have been described previously in literatures, this is the first report of ectopic hepatoid gland adenoma cases in dogs in South Korea.

Staphylococcus aureus is one of most prevalent intramammary pathogens and have characteristics which are not easily eradicated. Recently, to understand the sources and transmission of S aureus, many studies have focused on the subtyping of field isolate. This study was preformed to investigate the distribution pattern and characteristics of the isolates using phenotyping and genotyping. Samples were collected from milk of each udder, cow bodies (perianal region, vagina, tail, udder skin, sole) and environment (floor, liner, milker's hands, water, towel, insect) from 6 herds located in Kyung-gi province. Forty five strains of S aureus were isolated from 3 dairy herds (A, B, C) and were typed by hemolytic pattern, antibiotic resistant pattern, enterotoxin typing and PCR-based DNA fingerprinting. Slime productivity was also compared by each subtype to examine potential infectiousness. Of 45 strains, 41 were isolated from milk samples and 4 were isolated from liners. No strains isolated in the bodies and environment. Forty five strains isolated were classified as 18 subtypes by phenotyping and genotyping. There was common subtype between A and B herd, but the subtype of C herd showed different pattern. Among predominant subtypes, 60% of S aureus strain isolated from A and B herd showed subtype I and 50% of S aureus strain isolated from C herd belonged to subtype VI and X II. Neither somatic cell count (SCC) nor slime production was significantly different between predominant and minor subtypes. In summary, the study revealed that liners play more important roles in the mode of transmission than environmental sources. Several subtypes can be found in a herd, only a few subtype, however, was largely associated with the majority of infection.
