Ninety culled dairy cows were used in this study and were paired by weight and conformation similarity. Forty-five cows were arterially infused immediately after bleeding with 10% volume by weight of a solution composed of dextrose (.23%), glycerin (.21%), a phosphate blend (.14%) and maltose (.1%). The remaining cows (45) served as controls. In infused carcasses, some quantity of solution retained was in the following order: supraspinatus, chuck greater than longissimus, loin greater than semitendinosus, round muscles. Accordingly, percentage of protein, ether-extractable fat, and protein fat-free amounts were lowered (P less than .05) and percentage of moisture and moisture protein ratio were raised (P less than .05) in the supraspinatus muscle. Tenderness (P less than .01) and protein extractability (P less than .15) were improved. No difference was observed in water-holding capacity between infused and control carcasses. Percentages of moisture fat-free (r = .85) and protein fat-free (r = -.97) were highly correlated to moisture-protein ratio. Moisture percentage of the fat-free tissue was shown to be a more consistent indicator of added moisture in infused whole carcasses compared with moisture:protein ratio and percentage of protein fat-free. Very low correlations were observed between tenderness, percentage of moisture, percentage of water-holding capacity, and ether-extractable fat. The economics of the infusion process to the beef industry is discussed.

Tenderness was assessed by point count and by scored palpation in 51 patients with human immunodeficiency virus (HIV) infection as well as 51 patients with rheumatoid arthritis (RA) and 50 patients with psoriatic arthritis (PsA). Fifteen of 51 (29%) patients with HIV infection met criteria for fibromyalgia, based on the presence of 10 tender (of 14) "fibrositic" points. Similar results were observed among patients with PsA (24%). The prevalence of fibromyalgia was higher among patients with RA (57%). Patients with HIV and PsA were less tender than patients with RA. Fibromyalgia in patients with HIV was significantly associated with myalgia and arthralgia, but not with age, duration of HIV infection, stage of HIV disease, or zidovudine therapy.

Superior mesenteric vein thrombosis is an abdominal emergency that is rarely diagnosed early. Abdominal pain, vomiting, fever, and hematochezia are the characteristic presenting complaints. Tenderness, distension, and diminished intestinal sounds were the prominent abdominal physical findings in this case and were often associated with tachycardia and hypotension. This is a case that demonstrates all the nonspecifics, and one in which the patient survived beyond all others reported in the literature to date.

The three types of pain related to exercise are 1) pain experienced during or immediately following exercise, 2) delayed onset muscle soreness, and 3) pain induced by muscle cramps. Each is characterized by a different time course and different etiology. Pain perceived during exercise is considered to result from a combination of factors including acids, ions, proteins, and hormones. Although it is commonly believed that lactic acid is responsible for this pain, evidence suggests that it is not the only factor. However, no single factor has ever been identified. Delayed onset muscle soreness develops 24-48 hours after strenuous exercise biased toward eccentric (muscle lengthening) muscle actions or strenuous endurance events like a marathon. Soreness is accompanied by a prolonged strength loss, a reduced range of motion, and elevated levels of creatine kinase in the blood. These are taken as indirect indicators of muscle damage, and biopsy analysis has documented damage to the contractile elements. The exact cause of the soreness response is not known but thought to involve an inflammatory reaction to the damage. Muscle cramps are sudden, intense, electrically active contractions elicited by motor neuron hyperexcitability. Although it is commonly assumed that cramps during exercise are the result of fluid electrolyte imbalance induced by sweating, two studies have not supported this. Moreover, participants in occupations that require chronic use of a muscle but do not elicit profuse sweating, such as musicians, often experience cramps. Fluid electrolyte imbalance may cause cramps if there is profuse prolonged sweating such as that found in working in a hot environment. Thus, despite the common occurrence of pain associated with exercise, the exact cause of these pains remains a mystery.

This study was designed to test the hypothesis that performing repeated bouts of eccentric exercise when muscles were not recovered from previous exercise would exacerbate muscle damage. Twelve nonweight-trained males (21.7 +/- 2.4 yr) performed three sets of 10 eccentric actions of the elbow flexors (ECC) using a dumbbell that was set at 80% of the preexercise maximal isometric force level. This same exercise was repeated 3 and 6 d after the first exercise. Maximal isometric force, relaxed and flexed elbow joint angle, muscle soreness, plasma creatine kinase, and glutamic-oxaloacetic transaminase activities were assessed. Ultrasound images were taken from the upper arm. These measures (except soreness) were assessed immediately before and after each eccentric exercise bout (ECC1, ECC2, and ECC3) and 3 d after ECC3. Soreness was assessed prior to ECC1 and once a day for 9 d thereafter. All criterion measures changed significantly (P < 0.01) after ECC1. ECC2 and ECC3 performed 3 and 6 d after ECC1 did not exacerbate damage and did not appear to slow the recovery rate. Increased echointensity in ultrasound images was demonstrated following ECC1, but no indication of increased damage was found after ECC2 and ECC3. Strenuous exercise performed with "damaged" muscles did not exacerbate damage or affect the repair process.

Determining the number of swollen joints and tender joints is a key component in the clinical assessment of rheumatoid arthritis (RA). There have been a series of investigations carried out in the last decade, which have defined the best ways to measure joint inflammation and have identified which joints should be evaluated. There is not complete agreement on the optimal joint count, but two approaches are widely used. These comprise counting either 66/68 or 28 joints. The main difference is that the 28-joint count excludes the joints in the feet. Both methods give similar information and are reproducible and valid. Tenderness and swelling should be measured separately. There are advantages and disadvantages associated with using the 28-joint count. It has the benefit of simplicity and takes less time, although some potentially relevant clinical information about the feet may be lost. There is general agreement that grading the severity of individual joint involvement is of limited advantage. Using weighted joint counts is also not widely accepted. Finally there is growing recognition of the need for training in the methods of assessing joints and the importance of international standardization. Joint counts are a component of the core clinical data set for RA and will continue to play a key role in the foreseeable future.

The present experiment was conducted to determine 1) the repeatability of Warner-Bratzler shear force and trained sensory panel tenderness ratings in beef round cuts and 2) the effect of location within beef round cuts on shear force and tenderness ratings. Biceps femoris (BF) and semitendinosus (ST) were obtained from the carcasses of youthful (A-maturity), grain-fed, crossbred steers (n = 25) at 16 d postmortem. Steaks were removed from each muscle for determination of shear force and tenderness rating at each of three locations (A = proximal end, B = center, and C = distal end). Tenderness ratings of triplicate samples were slightly more repeatable than shear force for BF (R = .50 vs .30) and ST (R = .60 vs .56). However, all of those estimates of repeatability were much less than values we have obtained for beef longissimus using similar laboratory procedures (R = .79 to .90). Across both muscles and both methods of assessing tenderness, less than 40% of the total variance was accounted for by animal. The variance of tenderness rating among animals was less for BF (.12) and ST (.09) than values we have obtained for beef longissimus (.60). Location did not affect (P > .05) BF shear force; however, BF tenderness ratings were higher (P < .05) for location A (5.5) than for B (5.0) and C (5.2). Location accounted for a higher percentage of the total variance of ST tenderness rating and ST shear force than did animal. Shear force decreased (P < .05) from the proximal end to the distal end of ST (5.1, 4.6, and 3.9 kg for locations A, B, and C, respectively). Also, ST tenderness ratings were lower for location A (4.8) than for locations B (5.6) and C (5.7). Neither method of measuring tenderness was highly repeatable for BF or ST because there was little animal-to-animal variation in tenderness for these round muscles. Thus, there would be little opportunity for segregating round muscles into tenderness classes.

We conducted the present study to develop a clinical prediction rule for discriminating which patients with peripheral lymphadenopathy require a lymph node biopsy. The clinical features of 315 patients with peripheral lymphadenopathy were analyzed to develop the prediction rule: 83 had diseases requiring a lymph node biopsy (Lymph Node Biopsy Group [BG]), while 232 had diseases that could be diagnosed without a lymph node biopsy (Non-Lymph Node Biopsy Group [NBG]). Among 23 examined clinical covariates, we identified 6 that independently predicted the need for lymph node biopsy and were graded as follows: 1) Age: x1 = 0, if < or = 40 years and 1, if > 40 years. 2) Tenderness in palpation: x2 = 0, if absent and 1, if present. 3) Size of the greatest lymph node: x3 = 0, if < 1.0 cm2, 1 if 1.0-3.99 cm2, 2 if 4.0-8.99 cm2, and 3 if > or = 9.0 cm2. 4) Generalized pruritus: x4 = 1, if present and 0, if not. 5) Supraclavicular lymphadenopathy: x5 = 1, if present and 0, if not. 6) Texture: x6 = 1, if nodes are hard and 0, if not. The prediction rule was then validated in a subsequent group of 160 patients (32 in the BG; 128 in the NBG). A score Z = 5x1 - 5x2 + 4x3 + 4x4 + 3x5 + 2x6 - 6 corresponded to every patient, according to the results of logistic regression analysis. If patients with Z > or = 1 were considered to need lymph node biopsy, the sensitivity of the prediction rule was 95.2% (95% confidence intervals [CI]: 88.1%-98.1%) and the specificity was 81.0% (95% CI: 75.4%-85.6%). Within the Validation Group of patients the prediction rule was at least equally effective. Sensitivity was 96.9% (95% CI: 83.9%-99.5%) and specificity was 91.4% (95% CI: 85.1%-95.2%). The described rule can be useful in the clinical evaluation of patients with peripheral lymphadenopathy. Further validation by other groups is required, and its cost-effectiveness has to be investigated.

Using a multitrait animal model BLUP, selection was conducted over seven generations for growth rate (ADG), real-time ultrasound LM area (LMA), backfat thickness (BF), and intramuscular fat content (IMF) to develop a new line of purebred Duroc pigs with enhanced meat production and meat quality. This selection experiment examined 543 slaughtered pigs (394 barrows and 153 gilts) from the first to the seventh generation for meat quality traits. Further, electric impedance and collagen content of loin meat were measured from the fourth to sixth generation. The present study was intended to estimate genetic parameters of the correlated traits of tenderness (TEND), meat color (pork color standard: PCS; lightness = L*), drip loss (DL), cooking loss (CL), pH (PH), electric impedance (IMP), and collagen (COL) of the LM, and the genetic trends of these traits. Respective heritability estimates for IMF, TEND, DL, CL, PCS, L*, PH, IMP, and COL were 0.39, 0.45, 0.14, 0.09, 0.18, 0.16, 0.07, 0.22, and 0.23. Genetic correlations of IMF with ADG and BF were low and positive, but low and negative with LMA. Tenderness was correlated negatively with ADG (-0.44) and BF (-0.59), but positively correlated with LMA (0.32). The genetic correlation between LMA and DL was positive and high (0.64). The genetic correlations of TEND with IMF and COL were low (-0.09 and 0.26, respectively), but a moderate genetic correlation (0.43) between COL and IMF was estimated, suggesting related increases of IMF and connective tissue. Genetic correlations among meat quality traits suggested that when IMF increases, the water holding capacity improves. Genetic trends of meat quality traits showed increased IMF and lighter meat color.

Tenderness in the medial and posterior thigh is sometimes observed during the early postoperative period after total hip arthroplasty (THA). In this study, the possible correlations of preoperative hip range of motion, surgical approach, and limb lengthening with postoperative muscle strain injury in THA were investigated. Sixty primary THA patients given the posterolateral approach or direct-lateral approach were examined. For comparison of the muscle strain injury in the 2 groups, we used magnetic resonance imaging. There were significant differences in postoperative thigh pain between cases in the posterolateral group with reduction of internal rotation and those with no reduction, and between cases in the direct-lateral group with reduction of external rotation and those with no reduction.
