Septic epiglottic chondritis with abscessation diagnosed in 2 Thoroughbred racehorses. Infected cartilage removed videoendoscopically followed by systemic antibiotics. The infectious process was successfully controlled, but permanent dorsal displacement of the soft palate (DDSP) with a shortened, deformed epiglottic cartilage developed. Surgery for the DDSP using bilateral partial sternothyroidectomy or laryngeal tie-forward failed. 相似文献

OBJECTIVE: To (1) describe a caudal approach to equine medial and lateral femorotibial (FT) joints and (2) illustrate the complex anatomic detail of the caudal compartments of the lateral FT joint. STUDY DESIGN: Prospective experimental study. ANIMALS: Cadaveric equine hindlimbs (n = 36; 26 horses) and 6 horses (11 hind limbs). METHODS: Stifles (n = 8) were dissected and 10 FT joints were injected with silicone. Arthroscopic exploration (n = 29) was performed, followed by dissection to determine sites and structures penetrated during entry. RESULTS: A more caudal approach to the caudal pouch of the medial FT improved anatomic observation. A more caudal approach to the caudal pouch of the lateral FT joint occasionally caused damage to the common peroneal nerve; however, after reverting to the previously described approach, damage was avoided. CONCLUSION: Arthroscopy of the caudal pouch of the medial FT joint was facilitated using a more caudomedial approach, which improved observation of intrasynovial structures, most importantly, the caudal cruciate ligament and caudal horn of the medial meniscus. A more caudal approach to the caudal pouch of the lateral FT joint cannot be safely performed without risk to the common peroneal nerve and therefore the standard caudal approach is described in detail. CLINICAL RELEVANCE: A caudomedial arthroscopic approach allows improved surgical assessment of meniscal or caudal cruciate ligament injury. Care should be exercised when exploring the caudal pouch of the lateral FT joint because the common peroneal nerve is variably located and could easily be damaged during arthroscope or instrument insertion, especially if the limb is minimally flexed. 相似文献

The equine industry has a need for a convenient, rapid, and reliable method of measuring blood lactate concentrations ([LA]). We hypothesized that the handheld Lactate Plus lactate meter (LPlus), developed and tested for use in humans, would provide dependable results when used in horses undergoing an exercise conditioning program and that horse's fitness would improve following individualized conditioning based on each horse's velocity at which [LA] = 4 mmol/L (VLA4) was reached. Five adult horses underwent a 4-week training program that consisted of 3 exercise bouts/wk. Horses were subjected to an incremental step standardized exercise test (SET) before starting (SET-1) and after the completion of the program (SET-2). Blood samples were collected before each increase in speed until [LA] reached ≥4 mmol/L, and then the SET was terminated. The [LA] sample range in our study was 0–8 mmol/L. Blood was analyzed at the time of collection using a calibrated LPlus, and plasma was collected for [LA] determination using the lactate dehydrogenase–based enzymatic colorimetric method. Although the LPlus tended to significantly underestimate [LA] by 0.39 mmol/L (P < .001), the LPlus proved to be a dependable device for use in horses based on good correlation with the biochemical analysis (r = 0.978) and Bland–Altman limits of agreement and 95% confidence intervals. All horses showed an increase in VLA4 from SET-1 to SET-2, consistent with improved fitness following our 3 exercise bout/wk training protocol. The LPlus can reliably be used in horses to determine [LA] ranging from 0–8 mmol/L. When determining serial [LA], analytical techniques should not be used interchangeably. 相似文献

High prevalences of Cryptosporidium and Giardia were recently found in enteric illness patients in the Qikiqtaaluk region of Nunavut, Canada, with a foodborne, waterborne or animal source of parasites suspected. Clams (Mya truncata) are a commonly consumed, culturally important and nutritious country food in Iqaluit; however, shellfish may concentrate protozoan pathogens from contaminated waters. The goal of this work was to investigate clams as a potential source of Cryptosporidium and Giardia infections in residents in Iqaluit, Nunavut. The objectives were to estimate the prevalence and genetically characterize Cryptosporidium and Giardia in locally harvested clams. Clams (n = 404) were collected from Iqaluit harvesters in September 2016. Haemolymph (n = 328) and digestive gland (n = 390) samples were screened for Cryptosporidium and Giardia via PCR, and amplified products were further processed for sequence analyses for definitive confirmation. Giardia DNA was found in haemolymph from 2 clams, while Cryptosporidium was not detected. The two Giardia sequences were identified as zoonotic Giardia enterica assemblage B. The overall prevalence of Giardia in clams near Iqaluit was low (0.6%) compared with other studies in southern Canada and elsewhere. The presence of Giardia DNA in clams suggests human or animal faecal contamination of coastal habitat around Iqaluit in shellfish harvesting waters. Results from this study are intended to inform public health practice and planning in Inuit Nunangat. 相似文献

Three 21-year-old Appalachian hardwood stands were strip cut using three cutting widths (2.4-m, 3.7-m, and 4.9-m) and allowed to resprout. One year after strip cutting, we examined the vegetation response within the harvested strips relative to non-treated control areas, focusing on the sprouting ability of young hardwood stems and the herbaceous component for wildlife habitat. Results indicate the width of the strip cutting significantly affected the amount of biomass produced from stump sprouts (p = 0.042) and influenced species composition. Shade-intolerant species accounted for more of the biomass production within the wider cut strip widths, while shade-tolerant and shade-intermediate species were more prominent within the narrower cut strips. Cut strip width did not have a significant effect on the biomass of new seedlings germinating after the cuttings. Herbaceous vegetation was greater within the 4.9-m cut strips than in the control plots (p = 0.046); however, the amount of herbaceous biomass produced did not vary among months during the first growing season. Overall, our initial results suggest that strip cutting can provide benefits to wildlife and can possibly provide for additional biomass as the regrowth is harvested in the future. 相似文献
