Background: Surgery for the closure of nasal septal perforation is challenging. Numerous techniques have been described.

Objectives: To assess whether nasal septal perforations heal more consistently if a connective tissue scaffold is placed between the repaired septal flaps.

Methods: We performed closure of a septal perforation via a closed approach using oral mucosal flaps without the interposition of a connective tissue graft in seven patients.

Results: Complete perforation closure was achieved in 5 cases (83.3%). There was no significant donor site morbidity.

Conclusions: These initial results suggest that this is an effective technique for closing nasal septal perforations; it obviates the morbidity of the open approach and the added operating time and morbidity associated with the harvesting of a connective tissue graft.

Background: Emergency room triage of patients presenting with chest pain syndromes may be difficult. Under-diagnosis may be dangerous, while over0diagnosis may be costly.

Objectives: To report our initial experience with an emergency room cardiologist-based chest pain unit in Israel.

Methods: During a 5 week pilot study, we examined resource utilization and ER [1] diagnosis in 124 patients with chest pain of uncertain etiology or non-high risk acute coronary syndrome. First assessment was performed by the ER physicians and was followed by a second assessment by the CPU[2] team. Assessment was based on the following parameters: medical history and examination, serial electrocardiography, hematology, biochemistry and biomarkers for ACS[3], exercise stress testing and/or 64-slice multi-detector cardiac computed tomography angiography. Changes in decision between initial assessment and final CPU assessment with regard to hospitalization and utilization of resources were recorded.

Results: All patients had at least two cardiac troponin T measurements, 19 underwent EST[4], 9 echocardiography and 29 cardiac MDCT[5]. Fourteen patients were referred for early cardiac catheterization (same/next day). Specific working diagnosis was reached in 71/84 patients hospitalized, including unstable angina in 39 (31%) and non-ST elevation myocardial infarction in 12 (10%). Following CPU assessment, 40/124 patients (32%) were discharged, 49 (39%) were admitted to Internal Medicine and 35 (28%) to the Cardiology departments. CPU assessment and extended resources allowed discharge of 30/101 patients (30%) who were initially identified as candidates for hospitalization after ER assessment. Furthermore, 13/23 (56%) of patients who were candidates for discharge after initial ER assessment were eventually hospitalized. Use of non-invasive tests was significantly greater in patients discharged from the ER (85% vs. 38% patients hospitalized) (P < 0.0001). The mean ER stay tended to be longer (14.9 ± 8.6 hours vs. 12.9 ± 11, P = NS) for patients discharged. At 30 days follow-up, there were no adverse events (myocardial infarction or death) in any of the 40 patients discharged from the ER after CPU assessment. One patient returned to the ER because of chest pain and was discharged after re-assessment. 

Conclusions: Our initial experience showed that an ER cardiologist-based chest pain unit improved assessment of patients presenting to the ER with chest pain, and enhanced appropriate use of diagnostic tests prior to decision regarding admission/discharge from the ER.

Objective: To investigate hemodynamic variables, including small and large artery compliance, in cirrhotic patients during total paracentesis.

Methods: The study included 15 cirrhotic patients admitted for an episode of tense diuretic-resistant ascites. Hemodynamic variables including vascular compliance were measured using an HDI pulse wave cardiovascular profiling instrument CR-2000. The variables were measured in these patients before, immediately after and 24 hours following large volume (mean 5.6 L) paracentesis.

Results: Cardiac output increased immediately after paracentesis due to increment in stroke volume, with no change in heart rate. However, 24 hours later the cardiac output decreased to below the basal level. The fluctuation was statistically significant (P < 0.05). There was no change in large artery compliance, but small artery compliance increased after paracentesis (P < 0.05) and partially returned to the basal level after 24 hours. Systemic vascular resistance measurement showed the same pattern of change: vasodilatation occurred during paracentesis and was attenuated 24 hours later.

Conclusions: Large volume paracentesis with albumin replacement caused an accentuation of the vasodilatation (small but not large artery) already present in these patients. This may be the first sign of enhanced vasodilatation due to large volume paracentesis before the clinical expression of impaired hemodynamics and deterioration of renal function.

Background: Reports from Europe and North America indicate that significant changes have occurred in the practice of cardiac surgery in the last two decades.

Objectives: To examine the trends and case-mix in cardiac surgery in Israel and their relationship with changes in invasive cardiology.

Methods: We analysed data collected by the Ministry of Health from all cardiac centers in Israel from 1985 to 2002.

Results: Three periods were identified: the 1980s, when a relatively small number of operations were performed; 1990–1994, characterized by a dramatic rise in the number of operations; and 1994–present, characterized by a small decline and stabilization in the rate of operations. The percentage of valve procedures increased significantly from 15% of all cardiac surgeries in 1991 to 21% in 2002 (P = 0.002). In addition, the chance of a diagnostic coronary angiography being followed, in the same patient, by an interventional procedure such as percutaneous transluminal coronary angioplasty or by a coronary artery bypass graft increased dramatically from 42% in 1991 to 69% in 2002. At Rabin Medical Center, there was a constant decline in the percent of repeated CABGs[1] out of the total CABGs performed, from 6.7% in 1996 to 1.3% in 2002.

Conclusions: Despite the rise in the rate of percutaneous coronary interventions since 1991, there has been no significant decline in the rate of CABGs performed. However, there is a significant shift to more complex operations. The number of repeated CABG operations has significantly decreased and, in view of the growing use of arterial grafts and further improvements in invasive cardiology techniques, we expect this decline to continue.
