Synergistic finger movements in a skilled motor task.

When skilled typists strike one key, typically all of the fingers of one hand are in motion simultaneously. We studied the extent to which the motion of the individual fingers was similar. Subjects were asked to type lists of words, each word designed so that only one key would be pressed by a finger of one hand, the remaining letters being typed with the other hand. Changes in the lengths (flexion-extension) and orientation (abduction-adduction) of each finger were measured and the similarity of the motion of pairs of fingers was assessed by computing correlation coefficients. For each pair of fingers, the correlation coefficients were broadly distributed, but in most instances the mean was significantly greater than zero. Adjacent fingers showed a higher degree of correlation than did non-adjacent fingers. When one of the fingers was actually used to press the key, the degree of correlation decreased substantially. The results demonstrate that in this skilled motor task, the fingers usually tend to be moved together, but they can be moved independently when the task so requires.

Mesenteric microcirculatory changes in nonlethal hemorrhagic shock: the role of resuscitation with balanced electrolyte or hypertonic saline/dextran.

Class I and II hemorrhage has been routinely treated clinically with 2-2.5 times the volume of shed blood as balanced electrolyte solution. Although this regimen has been shown to adequately restore arterial pressure in trauma patients, it is not clear that it uniformly restores regional perfusion. Since it is becoming apparent that the gut plays a major role in the development of the posttraumatic septic state, we studied the effects of graded doses of balanced electrolyte resuscitation on the mesenteric microcirculation. Regimens consisting of one (1 x LR), two (2 x LR), or three (3 x LR) times the volume of shed blood as lactated Ringer's (LR) solution or 7.5% hypertonic saline and 6% dextran (HSD) equal to one seventh the volume of shed blood were given to groups of anesthetized (urethane-chloralose) male Sprague-Dawley rats after 30 minutes of hemorrhage to 50% of baseline mean arterial blood pressure. The microcirculation of the distal ileum was observed using an in vivo video microscope. Mean arterial pressure and ileal A1 diameters returned to baseline values with HSD within 20 minutes following this moderate hemorrhage. Additionally, A1 diameters returned to baseline in the 2 x LR and 3 x LR groups. A1 vessels remained significantly constricted in the 1 x LR group. Mean arterial pressure remained significantly lower than the baseline value in all of the LR groups. We conclude that in this model, HSD is superior to LR for restoration of blood pressure. In restoring A1 diameters, LR is equivalent to HSD only when volumes of balanced electrolyte two and three times shed blood volume are given.

Aneurysm of a common digital artery: case report and literature review.

The authors' recent experience of a 46-year-old woman with an aneurysm of a common digital artery led them to review the appropriate treatment for this rare condition. They found only one other reported case. In most reports on aneurysms of hand vessels, the aneurysm is of traumatic origin, but this was not the case in their patient. For such a rare condition, the authors emphasize the need for acute awareness of its possibility, angiography to evaluate the collateral circulation and early excision to relieve symptoms and avoid neurologic damage.

Hypersensitivity lung disease: early diagnosis.

The early diagnosis of hypersensitivity lung disease (HLD) is important because of its progressive morbidity. It is often difficult to establish the diagnosis in the early stages because of the absence of defined symptoms. Case histories of 2 patients with pigeon breeder's HLD are reported. Both patients presented with unusual manifestations of the disease: one patient was asymptomatic but had an abnormal chest radiograph; the other patient had a normal chest radiograph but experienced occasional symptoms of exertional dyspnea. Both patients had abnormal pulmonary function and precipitin bands against pigeon serum. Following inhalation challenge with pigeon serum both patients developed fever and leukocytosis, but no significant pulmonary function response was observed. In both patients pulmonary function tests returned to near normal levels after corticosteroid therapy. Early detection of HLD may prevent progressive irreversible pulmonary damage. This requires a high index of clinical suspicion and appropriate screening tests. Inhalation challenge procedures are useful in establishing the diagnosis.
