An 18-year-old miniature Appaloosa stallion presented with 6 months of history of sanguineous crusts on medial hind limbs and discomfort of micturition. Cauliflower-like and small masses were treated with cryotherapy for 6 months, but the regrowth of masses occurred. Subsequently, local excision via laser and topical treatment with 5% 5-fluorouracil for 5 months were followed. However, the horse was euthanized 4 months later due to regrowth of the masses. The mass was diagnosed as penile papilloma with cellular atypia and Equus caballus papillomavirus type 2 (EcPV-2) DNA was detected. This is the first report of equine penile neoplasm with EcPV-2 infection in Asia.

OBJECTIVES: To investigate the effects of microelectric treatment by transcutaneous electrical nerve stimulation (TENS) on functional recovery and histological changes in a rat model of spinal cord injury (SCI).SUMMARY OF LITERATURE REVIEW: The effects of TENS on spasticity and its underlying mechanisms remain unclear. MATERIALS AND METHODS: SCI was induced by a 1.5-mm impactor with 200,000–260,000 dyne after laminectomy. Rats were divided into the following groups: group I (normal control), group II (microelectric treatment of 0 A), group III (microelectric treatment of 100 µA for 1 hr/day), group IV (microelectric treatment of 400 µA for 1 hr/day), and group V (microelectric treatment of 400 µA for 24 hr/day). After inducing SCI, rats were assessed by a sensory test with von Frey filaments and the locomotor recovery test (BBB rating scale) at 1, 4, 7, 14, 21, and 28 days. To evaluate spinal cord damage, histopathological studies were performed with hematoxylin and eosin. Brain-derived neurotrophic factor (BDNF) and TrkB immunohistochemistry studies were performed at 28 days. RESULTS: In groups IV and V, the BBB score had significantly improved on days 21 and 28 after SCI, and the TENS-treated groups showed significant neuronal recovery. After SCI, groups IV and V showed a significant recovery of locomotor function and the motor sensory response of the withdrawal threshold to 3.5 g. In addition, necrotic tissue and cystic spaces in the spinal cord were significantly reduced and BDNF/TrkB-positive cells were highly expressed in groups III, IV, and V. CONCLUSIONS Microelectric treatment can play a role in facilitating the recovery of locomotion following SCI.

Acute puerperal uterine inversion is a rare postpartum obstetric complication; however, without rapid diagnosis and appropriate management, it is life-threatening. Substantial bleeding hinders the verification of a partially inverted uterus, possibly delaying the treatment. Herein, we present the report of a 32-year-old female presenting with massive postpartum bleeding managed by uterine artery embolization. The peculiar course of the uterine artery bowing inferiorly along the inverted fundus during embolization could uncover the uterine inversion, which was not diagnosed by physical examination and CT. In conclusion, uterine artery embolization is not only an effective therapeutic strategy for postpartum hemorrhage but also a valuable tool for diagnosing uterine inversion.

We evaluated the performance of a recently developed immunoassay, Elecsys vitamin D total II assay (Roche Diagnostics GmbH, Germany). Precision, linearity, and comparison studies were performed according to the Clinical and Laboratory Standards Institute guidelines. Control materials, linearity materials, and patient samples were used for the evaluation. For the correlation study, liquid chromatography-tandem mass spectrometry was used as the comparative method. Total coefficients of variations of the analyte were between 5.1% and 9.6%. The results of linearity evaluation were also acceptable for the range tested. Correlations with comparative methods were good; however, the mean values of the Elecsys vitamin D assay were higher than those of liquid chromatography-tandem mass spectrometry. The overall analytical performance of the Elecsys vitamin D total II assay is acceptable for the immunology analyzer. Therefore, the Elecsys vitamin D total II assay is expected to be widely used.
