Medical and pharmacy student concerns about participating on international service-learning trips.

BACKGROUND: International Service Learning Trips (ISLT) provide health professional students the opportunity to provide healthcare, under the direction of trained faculty, to underserved populations in developing countries. Despite recent increases in international service learning trips, there is scant literature addressing concerns students have prior to attending such trips. This study focuses on identifying concerns before and after attending an ISLT and their impact on students. METHODS: A survey comprised of closed and open-ended questions was developed to elucidate student concerns prior to attending an ISLT and experiences which might influence concerns. A five-point Likert-scale (extremely concerned = 1, minimally concerned = 5) was used to rate apprehension and satisfaction. Paired t-test was used to compare pre- and post-trip concerns; Chi-Square test was used to compare groups. RESULTS: Thirty-five students (27 medical, 8 pharmacy) attended ISLTs in December 2013. All completed pre and post-trip surveys. Significant decreases were seen in concerns related to cultural barriers (4.14 vs 4.46, P = .047), disease/epidemics (3.34 vs 4.60, P < .001), natural disasters (3.94 vs 4.94, P < .001), terrorism (4.34 vs 4.94, P < .001), travel (3.86 vs 4.51, P < .001) monetary issues (3.80 vs 4.60, P < .001), hospitality (3.94 vs 4.74, P = .001) and food (3.83 vs 4.60, P < .001). Language and group dynamics remained concerns post-trip. On open-ended questions, students described benefits of attending an ISLT. CONCLUSIONS: Students had multiple concerns prior to attending an ISLT. Most decreased upon return. Addressing concerns has the potential to decrease student apprehension. The results of this study highlight the benefits of providing ISLTs and supporting development of a curriculum incorporating trip-related concerns.

Atrial fibrillation ablation in patients with gastroesophageal reflux disease or irritable bowel syndrome-the heart to gut connection!

PURPOSE: An association between atrial fibrillation (AF) and gastroesophageal reflux disease (GERD) and/or irritable bowel syndrome (IBS) is increasingly being identified; yet the role of radiofrequency catheter ablation (RFA) of AF has not been systematically evaluated in these patient populations. METHODS: We performed a prospective matched case-control study of AF patients with GERD and/or IBS who underwent RFA for AF in two centers in North America. AF patients with GERD and/or IBS (gastrointestinal [GI] group) were matched by age, gender, and type of AF at each of the centers with an equal number of AF patients without GERD or IBS (non-GI group). RESULTS: Sixty patients were included in the study with 30 in each group. Mean age of the population was 45 years with 14 (47 %) males and 21 (87 %) patients with paroxysmal AF in each group. More patients in the GI group had identifiable GI triggers for AF episodes. During RFA, more patients in the GI group had a "vagal response" compared to non-GI group (60 vs 13 %; p < 0.001). Left atrial scar as identified by electroanatomical mapping was more common in patients in the non-GI group compared to the GI group (57 vs 27 %; p = 0.018). At 1-year follow-up, 56 (93 %) of the patients were free from AF with no difference between both groups. CONCLUSIONS: Majority of AF patients with GERD and/or IBS have triggered AF and a positive vagal response during RFA. RFA is equally effective in this patient population when compared to those without GERD or IBS.

Postprocedural neuropathy after atrial fibrillation ablation.

PURPOSE: Access-related neuropathy after atrial fibrillation (AF) ablation is underappreciated. We intend to describe the incidence, management, and prognosis of postprocedural neuropathy after AF ablation. METHODS: We performed a retrospective analysis of all consecutive patients with postprocedural neuropathy who underwent AF ablation in three high-volume tertiary care hospitals between January 2007 and April 2011. RESULTS: Of the 3,128 patients who underwent AF ablation during the study period, 25 (0.8 %) patients had postprocedural neuropathy and were included in the current study. Mean age was 58.5 ± 11.5 years with 18 (72 %) being males and 14 (56 %) having paroxysmal AF. Ulnar nerve, lateral femoral cutaneous nerve manifesting as meralgia paresthetica, and femoral nerve were involved in 5 (20 %), 13 (54 %), and 7 (26 %) of the patients, respectively. Majority of neuropathies were associated with periprocedural hematomas (19, 76 %), and a quarter (19/72, 26 %) of all hematomas were associated with neuropathy. Initial treatment included warm and cold compresses followed by nonsteroidal anti-inflammatory and narcotic pain medications. In addition to the above regimen, in some patients (11, 44 %), oral gabapentin was used and it was associated with a shorter time to symptom resolution (9.4 vs. 14.1 days, p = 0.007). All patients were symptom free within 90 days of the procedure. CONCLUSION: Postprocedural neuropathy after AF ablation is rare and is frequently associated with a periprocedural hematoma. Patients typically become symptom free within 90 days of the procedure, and gabapentin may have a role in earlier symptom resolution.
