What's Eating You? Update on the Sticktight Flea (Echidnophaga gallinacea).

The sticktight flea (Echidnophaga gallinacea), a carrier of plague (Yersinia pestis), rickettsial infections, and other diseases, can be found in warm climates. The flea attaches to a host by embedding its head in the skin for days at a time. Most human infestations occur in individuals who handle infested animals.

Riding the wave: a quantitative report of electrocardiogram utilization for myocardial infarction confirmation.

The purpose of this study was to generate a quantitative profile of electrocardiograms (ECGs) for confirming surgical success of permanent coronary artery ligation. An ECG was recorded at baseline, and 0, 1, and 5 min after ligation and analyzed using iWorkx LabScribe software. (C57Bl6/J, = 8/sex) was enrolled to determine ECG characteristics that were confirmed in (C57Bl6/J, = 6/sex; = 6 males/4 females).

Report generation using digital speech recognition in radiology.

The aim of this study was to evaluate whether the use of a digital continuous speech recognition (CSR) in the field of radiology could lead to relevant time savings in generating a report. A CSR system (SP6000, Philips, Eindhoven, The Netherlands) for German was used to transform fluently spoken sentences into text. Two radiologists dictated a total of 450 reports on five radiological topics.

Group remembering: does social loafing underlie collaborative inhibition?

When people collaborate to recall information, they experience collaborative inhibition, a deficit in recall relative to nominal groups (the pooled, nonredundant recall of individuals working alone). That is, people recalling in groups do not perform up to their potential. Collaborative inhibition may be due to retrieval interference (e.

A comparative evaluation of substance abuse treatment: V. Substance abuse treatment can enhance the effectiveness of self-help groups.

Affiliation with Alcoholics Anonymous (AA) and other 12-Step self-help groups is becoming more common at the same time as professional substance abuse treatment services are becoming less available and of shorter duration. As a result of these two trends, patients' outcomes may be increasingly influenced by the degree to which professional treatment programs help patients take maximum advantage of self-help groups. The present study of 3018 treated veterans examined how the theoretical orientation of a substance abuse treatment program affects (1) the proportion of its patients that participate in self-help groups, and, (2) the degree of benefit patients derive from participation in self-help groups.

Injury of the Achilles tendon: diagnosis with sonography.

We determined the diagnostic accuracy of sonography for the assessment of injury to the Achilles tendon. After anatomic investigations in three human cadavers, we performed a clinical study in 24 healthy volunteers and 73 symptomatic patients referred for achillodynia or signs of heel thickening or both in whom a clinical diagnosis of acute total rupture was excluded. High-resolution real-time sonography was performed and the results were compared with final clinical diagnoses (55 patients) and surgical findings (18 patients).

Primary pulmonary lymphoma in a patient with the acquired immune deficiency syndrome.

A case of primary pulmonary lymphoma presenting as a nodular lesion on the chest radiograph in a patient with the acquired immune deficiency syndrome is described.

Anomalous pulmonary venous drainage shown by duplex sonography, computed tomography, and plain radiography.

In a patient with the scimitar syndrome duplex Doppler sonography was used to show the point of entry of the abnormal pulmonary vein into the inferior vena cava to determine blood flow. Chest radiography and computed tomography also showed the vein descending to the diaphragm.

Duplex sonography of normal renal allografts.

Thirty-five patients with normal renal allografts as well as 10 healthy volunteers with normal native kidneys were examined by duplex sonography. Blood flow measurements were performed in the main renal artery as well as in segmental, interlobar and arcuate arteries. In both groups the normal range of variation in blood flow was defined by using the resistive index (RI).

Pulmonary veno-occlusive disease in a patient with unilateral absence of right pulmonary artery.

A 25-year-old patient had unilateral absence of the right pulmonary artery (UARPA) and severe left pulmonary artery hypertension. After death from congestive right heart failure, autopsy revealed histologic signs of pulmonary veno-occlusive disease (PVOD) and pulmonary hypertension (PH). An accessory arterial vessel that was thrombotically occluded was found connecting the ascending aorta and the right pulmonary hilum.
