Lymphadenitis is the most common manifestation of non-tuberculous mycobacteria infection in children. Its frequency has increased over the past few decades. Diagnosis is based on clinical presentation, purified protein derivative skin test, and bacterial isolation. Management options are surgery, antibiotics, or "observation only"; however, the optimal therapy for this condition is still controversial.

Background: Injury to patent grafts or cardiac chambers may occur during reoperation after coronary artery bypass grafting. Preoperative spatial localization of bypass grafts with computed tomography may improve the safety of these procedures.

Objectives: To characterize patients who undergo CT before repeat operations after previous coronary artery bypass grafting, and evaluate its benefit in terms of surgical outcome.

Methods: We compared 28 patients who underwent cardiac gated CT angiography before reoperation (CT group) to 45 re-do patients who were not evaluated with CT (no‑CT group).

Results: The two groups were similar in most preoperative and operative characteristics. The CT group, however, included more patients with patent saphenous vein grafts and fewer with emergency operations, acute myocardial infarction and need for intraaortic balloon pump support. During mid-sternotomy, there was no injury to grafts in the CT group, while there were two patent grafts and three right ventricular injuries in the no-CT group. There was no significant difference in perioperative mortality (3.6% vs. 8.9%). The overall complication rate in the CT group was 21.4% compared to 42.2% in the no‑CT group (P = 0.07). The only independent predictors of postoperative complications were diabetes mellitus, preoperative stroke and preoperative acute MI[1].

Conclusions: The patency and proximity of patent grafts to the sternum are well demonstrated by multidetector CT and may provide the surgeon with an important roadmap to avoid potential graft injury. A statistical trend towards reduced complications rate was demonstrated among patients who underwent CT angiography before their repeat cardiac operation. Larger series are required to demonstrate a statistically validated complication-free survival benefit of preoperative CT before repeat cardiac surgery.

Background: Medication errors are a common cause of morbidity and mortality.

Objectives: To evaluate the rate of acknowledgment of medication errors as reported by physicians working in the community and in hospitals.

Methods: An anonymous questionnaire was sent to 9320 active physicians (about 48% community physicians, 17% hospital physicians and 35% working in both places), with questions on the rate and type of medication errors that they had encountered during their professional career. The questions specified errors in dosage, type of medicine (wrong indication), route of administration and drug interactions.

Results: Only 627 physicians (6.7%) responded. Of these, nearly 79% admitted having made an error in prescribing medication; the majority admitted to more than one error. Physicians with fewer years of experience admitted having made a mistake more than did physicians with more experience (P = 0.019). Pediatricians and geriatricians made more dosage mistakes (P = 0.02), while family physicians and psychiatrists made more mistakes in drug interactions (P = 0.001).

Conclusions: It is possible that indifference, fear of identification, or lack of awareness may have contributed to the low response rate despite the fact that the questionnaire was anonymous. Educational programs should be implemented in medical schools to encourage physicians to report errors before the onset of adverse reactions.
 

Background: Carotid artery stenting is used as an alternative to surgical endarterectomy.

Objectives: To determine the outcome of CAS[1] in a retrospective cohort of patients.

Methods: Between July 1999 and March 2003, 56 consecutive patients with carotid artery stenosis who were considered ineligible for surgery were treated (45 male, 11 female, mean age 69). All cases were performed prior to the introduction of distal protective devices in Israel.

Results: Intraprocedural complications included transient neurological findings in 5 patients (8%), cerebrovascular accident in 2 (3%), hemodynamic changes in 11 (18%), and 4 procedural failures. Post-procedural complications included transient ischemic attack in 3 patients and cardiovascular accident in 6 (10%). At 30 days follow-up, three patients (5%) remained with signs of CVA[2]. Two patients (3%) died during the post-procedural period and 16 (28%) during the 5 year follow-up, one due to recurrent CVA and the remainder to non-neurological causes. Five-year carotid Doppler follow-up was performed in 25 patients (45%), which revealed normal stent flow in 21 (84%), 50–60% restenosis in 3 patients (12%) and > 70% restenosis in one patient (4%).

Conclusions: This study confirms that stent procedures are beneficial for symptomatic carotid stenosis in patients not eligible for surgery.

Research findings have shown the protective effect of religiosity – among both Christians and Israeli Jews – in terms of morbidity and mortality. To explore the relationship between religiosity and health behavior as a possible explanation for these findings we conducted 3056 telephone interviews, representing the Israeli adult urban Jewish population. Health status, health behavior, frequency of medical checkups, and eating habits were measured. Logistic regressions were used to estimate the religiosity gradient on health behavior, controlling for other personal characteristics. We found a lower prevalence of stress and smoking among religious persons; we also found that religious women exercise less than secular women and that religious people – both men and women – are more obese than their secular counterparts. While no religiosity gradient was found with relation to the frequency of blood pressure, cholesterol and dental checkups, religious women are less likely to undergo breast examinations and mammography. Finally, religious people generally follow a healthier dietary regime, consuming less meat, dairy products and coffee, and much more fish. The lower smoking rates, lower levels of stress, and the healthier dietary regime are consistent with the previously shown longer life expectancy of religious people; however, obesity might become a risk factor in this community.
