Primary cardiac lymphomas represent an extremely rare entity of extranodal lymphomas and should be distinguished from secondary cardiac involvement of disseminated lymphomas belonging to the non-Hodgkin’s classification of blood cancers. Only 90 cases have been reported in literature. Presentation of cardiac lymphomas on imaging studies may not be unambiguous since they potentially mimic other cardiac neoplasms including myxomas, angiosarcoma or rhadomyomas and therefore require multimodality cardiac imaging, endomyocardial biopsy, excisional intraoperative biopsy and pericardial fluid cytological evaluation to establish final diagnosis.

Auricular acupuncture at the relaxation point has been shown to be effective treatment for anxiety. We hypothesized that auricular acupressure may decrease anxiety in elderly individuals who are transported by ambulance before receiving ESWL. We enrolled 100 patients with renal calculi who were transported to the local hospital by special ambulance, accompanied by 2 paramedics. Paramedic 1 performed data collection, while paramedic 2 performed auricular acupressure in patients randomly assigned to a relaxation group and a sham treated group. Anxiety was measured using a visual analog scale score on a scale of 0 to 100 mm. Each group consisted of 50 patients with similar demographic characteristics. The relaxation group had significantly decreased anxiety scores upon arrival at the hospital and lower anticipation of pain scores (mean+/-SD 57.6+/-21.8 to 15.4+/-9.8 and 35.7+/-29.7 to 9.5+/-4.1 mm VAS) than the sham treated group (55.5+/-25.9 to 49.8+/-28.9 and 37.7+/-24.1 to 33.8+/-25.2 mm VAS, respectively, 2-way repeated measure ANOVA each p=0.001). Estimated waiting times for treatment did not differ significantly between the 2 groups (5.0+/-2.5 and 5.5+/-2.95, respectively, repeated measures ANOVA p=0.83). The Post-Intervention Anxiety visual analog scale demonstrated the significant superiority of the true treatment group (19.5+/-5.9 and 66.8+/-27.9 mm VAS, respectively, p=0.001). Elderly patients who received auricular acupressure at specific relaxation points while being transported to the hospital were less anxious, anticipated less pain and were more optimistic about the outcome of treatment that they will receive than the sham treated group. These data prove that this is an effective treatment for anxiety that improves the patient overall perception of ESWL.

Background: Training in transesophageal echocardiography (TEE) is based on hands-on training in the operating room, which is time consuming and therefore limits its experience among anesthesiologists. Medical simulations have been successfully used for training of invasive procedures in many areas. This paper compares the difference in effectiveness of teaching the 11 basic TEE views using either e-learning, simulation based training or hands-on training in the operating room in 3 groups of residents. Methods: We included 51 anesthesia and intensive care residents of all training levels but no prior training in echocardiography in this prospective randomized single-center study. Residents received a tutorial about theoretical knowledge followed by 2 practical study sessions either by e-learning using an online simulator (www.pie.med.utoronto.ca/TEE), with the simulation mannequin (CAE Vimedix Simulator) or in the operating room. Both, a theoretical multiple choice test (0–50 points) and a practical exam test (0–110 points) on the simulation mannequin had to be completed. The primary endpoint was the post-training scores in the practical and theoretical exams after all training sessions. Results: Residents received significantly higher test scores in both practical and theoretical examinations after training with the simulation mannequin (108.41 ± 2.09, 40.6 ± 5.23, n = 17) compared with e-learning (106.88 ± 4.53, 36 ± 4.76, n = 17) or hands-on training (106.82 ± 2.01, 34.94 ± 4.72, n = 17). Conclusions: Simulation based TEE training provides more effective training than other teaching methods. It is therefore especially suitable for the initial stages of TEE training to acquire psychomotor skills and knowledge of echo-anatomy.

Acute renal colic is one of the most anguishing forms of pain in humans. We hypothesized that TENS is an effective pain treatment in patients with acute renal colic. A total of 100 patients with acute flank pain and suspected renal colic consented to participate in our study. Paramedic 1 recorded baseline parameters at the emergency site and at the end of transportation. Paramedic 2 performed TENS in patients randomly assigned to G1 with actual TENS or to G2 with sham TENS. Pain and anxiety were measured using paper based visual analog scales on a scale of 0 to 100 mm. Of 100 screened patients 73 had renal colic, including 39 in G1 and 34 in G2. There was no significant difference with regard to potentially influencing factors, such as patient age, sex, weight, height, blood pressure and heart rate, pain, nausea and anxiety between the groups before treatment. G1 showed a significant mean pain decrease +/- SD of more than 50% (85.7 +/- 10.5 to 33.3 +/- 16.0 mm, p <0.01). G2 showed no variation in mean pain scores (85.8 +/- 18.0 to 82.6 +/- 14.3 mm). G1 showed changes in the mean anxiety score (69.0 +/- 8.4 to 37.7 +/- 15.1 mm, p <0.01), nausea score (90.7 +/- 9.2 to 44.9 +/- 22.0 mm) and heart rate (92 +/- 10 to 64 +/- 8 bpm), while G2 showed nonsignificant changes. This trial shows that local TENS is a rapid and effective treatment for renal colic pain. We found TENS to be a good nondrug therapy under the difficult circumstances of out of hospital rescue.
