“…Correlation coefficients of the relationship between ultrasound measure and organ mass in knots (0.792-0.928) are comparable with those found for swans (Cygnus olor, 0.929;Sears 1988), dippers (Cinclus cinclus, 0.859;Newton 1993), and canaries (Serinus canaria, 0.927;Newton 1993) and also with the range of the correlation coefficients between the ultrasound measure and fat thickness or muscle area in beef cattle (Perkins et al 1992;Herring et al 1994). Values obtained in plovers were substantially lower (0.118-0.820), however.…”

“…The three brands of equipment used in this study were equipped with different probes and screens, but repeatabilities generally were comparable (Table 2) and in the same range as found in previous studies (Perkins et al 1992;Herring et al 1994). However, while variation between equipment in the discrepancy between observed and predicted organ mass was small for pectoral muscles, when estimating stomach mass, the discrepancies appeared slightly higher for the Aloka equipment compared with Hitachi and Pie (Table 3).…”

“…Variation between observers was not investigated here, but previous studies have suggested that observer effects decrease as observers gain more experience (Perkins et al 1992;Herring et al 1994). Furthermore, we expect that the experience required is specific for particular organ/species combinations.…”

“…Some noninvasive methods currently are available to monitor organ size in live animals: x-ray techniques (Fuller et al 1994;Duke et al 1997), nuclear magnetic resonance (Fuller et al 1994;Wasser et al 1996), and ultrasonographic scanning (Newton 1993;Fuller et al 1994;Herring et al 1994). Each method has certain advantages and disadvantages (Fuller et al 1994), and most techniques are not suitable for estimating the size or mass of particular organs.…”

“…Today, ultrasound technique also involves ultrasonographic imaging, which has the major advantage that the "landscape" of the internal organs and skeleton is visible. Ultrasonographic measurements distress animals relatively little and are commonly used in humans and animals for diagnostic purposes (e.g., Grooters et al 1994;Lambertz et al 1995) and in the context of animal production (e.g., Perkins et al 1992;Herring et al 1994;Chiba 1995). Ultrasonography has been used in a few ecophysiological studies (e.g., Sears 1988;Newton 1993;Reimers et al 1993;Woodroffe 1995;Haefner et al 1996).…”

Organs, even of fully grown adult birds, mammals, and reptiles, may show substantial size changes in relation to specific performances. These changes are difficult to study, because measurements usually can only be obtained following the death of the animal. We explored the use of ultrasonographic imaging, a relatively simple noninvasive technique, to measure size of pectoral muscles and stomach in two small shorebird species (red knots Calidris canutus and golden plovers Pluvialis apricaria). Accuracy of ultrasound measurements in estimating organ mass in red knots was reasonably high. Depending on the equipment used, the error of individual measurements was 20%-25% for the pectoral muscles and 26%-44% for the stomach. In plovers the technique was less accurate, probably because of the low variability of the organs involved. Ultrasound scanning is particularly suited to measure rapidly changing organ sizes over short time intervals. We demonstrate this with an example in which changes in individuals in size of pectoral muscle and stomach were monitored in captive red knots following a change in diet. Ultrasound measures will enable studies on the links between body composition and future behavior and physiology.

Objective: To describe the clinical characteristics and outcomes in a population of dogs with negative-pressure pulmonary edema (NPPE) and to identify the main causes of the disease. To evaluate any associations with morbidity and mortality.Design: Retrospective study.Setting: Three university teaching hospitals and two private referral centers.Animals: Thirty-five client-owned dogs presented with NPPE. Interventions: NoneMeasurements and Main Results: Data collected included patient characteristics, clinical history, clinicopathological abnormalities, radiographic features, treatments and outcome. Median age was 4 months (range 2-90) and median weight was 7.1 kg (range 1.7-37.2). There were many causes of NPPE including leash tugs, near hanging, accidental choking, anatomical obstruction to airflow and purposeful airway obstruction by people. The most common cause of NPPE was accidental choking (40% of cases). Dogs with an anatomical obstruction were older than 24 months. Hypoxemia with an increased alveolar-arterial gradient was common on presentation. The majority of thoracic radiographs (65.7%) showed an alveolar or interstitial pattern in the caudodorsal area as previously described in the literature. Oxygen therapy was administered to 33 (94.3%) dogs. Furosemide was administered to 18 (51.4%) dogs. Median length of hospitalization was 2 days (range 0-14). Twenty-eight (80%) dogs survived to discharge. Seven dogs were mechanically ventilated and only 2 of them (28.6%) 2 survived to discharge. Requirement for mechanical ventilation (p<0.001) was the only parameter associated with mortality.Conclusions: Most cases of NPPE occur in juvenile dogs. Different incidents associated with upper airway obstruction can produce an episode of NPPE.Choking on food or toys and near hanging have not been previously described in the veterinary literature as inciting causes of NPPE. The overall prognosis is good.
