Background: Asthma control and treatment compliance are widely investigated issues around the world. Studies have demonstrated relatively low asthma compliance and control in 40–90% of asthma patients in different countries. There are no available data on the Israeli adult asthmatic population

Objectives: To investigate the level of asthma control and compliance in adult asthmatic patients.

Methods: This cross-sectional study of consecutive adult asthmatic patients visiting the pulmonary clinic used a combined questionnaire that included demographics, data on asthma severity and management, and asthma control and compliance scores. Each patient was interviewed and questionnaires were filled out during a routine visit.

Results: The study group comprised 142 males (35.4%) and 259 females (64.6%). Compliance was found optimal in 8 patients (2%), fair in 146 (36%), partial in 156 (39%) and poor in 92 (23%) of the participating asthmatic patients. Asthma control was found optimal in 26 (7%), fair in 124 (31%), partial in 122 (30%) and poor in 129 (32%) patients. Sephardic and Ashkenazi Jewish origin, higher level of education, and treatment protocol including either single fixed-dose inhalers or short-acting beta-agonist bronchodilators significantly improved compliance in our cohort. Socioeconomic status and compliance were found to positively affect asthma control, whereas active smoking negatively affected asthma control in the study patients.

Conclusions: The figures of optimal asthma control and compliance to treatment in Israeli adult asthmatics are low and worse than reported in other studies abroad.
 

Background: Coronary heart disease and ischemic stroke are among the leading causes of morbidity and mortality in adults, and cerebrovascular disease is associated with the presence of symptomatic and asymptomatic CHD[1]. Several studies noted an association between coronary calcification and thoracic aorta calcification by several imaging techniques, but this association has not yet been examined in stable angina pectoris patients with the use of spiral computed tomography.

Objectives: To examine by spiral CT the association between the presence and severity of CC[2] and thoracic aorta calcification in patients with stable angina pectoris.

Methods: The patients were enrolled in ACTION (A Coronary Disease Trial Investigating Outcome with Nifedipine GITS) in Israel. The 432 patients (371 men and 61 women aged 40–89 years) underwent chest CT and were evaluated for CC and aortic calcification.

Results: CC was documented in 90% of the patients (n=392) and aortic calcification in 70% (n=303). A significant association (P < 0.05) was found between severity of CC and severity of aortic calcification (as measured by area, volume and slices of calcification). We also found an association between the number of coronary vessels calcified and the presence of aortic calcification: 90% of patients with triple-vessel disease (n=157) were also positive for aortic calcification (P < 0.05). Age also had an effect: 87% of patients ≥ 65 years (n=219) were positive for both coronary and aortic calcification (P = 0.005) while only 57% ≤ 65 (n=209) were positive for both (P = 0.081).

Conclusions: Our study demonstrates a strong association between the presence and severity of CC and the presence and severity of calcification of thoracic aorta in patients with stable angina pectoris as detected by spiral CT.

Background: The use of the bilateral internal mammary arteries has been reserved mainly for younger and low risk patients.

Aim: To assess the safety and efficacy of BIMA[1] grafting in older patients (≥ 70 years).

Methods: We reviewed the records of all consecutive patients ≥ 70 years old who underwent coronary artery bypass surgery with a BIMA graft in our institute over a 2 year period. Demographic data, operative data, perioperative morbidity and mortality were recorded. Findings were compared with a matched-size group of patients who underwent CABG[2] with a left internal mammary artery graft to left anterior descending artery.

Results: The study sample included 136 patients, of whom 68 underwent BIMA grafting and 68 LIMA[3] grafting. Baseline demographic and clinical characteristics were similar in the two groups. There was no significant difference in operative mortality between the BIMA and LIMA groups (1.5% vs. 0%, P = 0.3) or in mortality during follow-up at a mean of 16 months (4.4% vs. 2.9%, P = 0.4, respectively). There was no difference between the groups in the incidence of perioperative complications, re-admission and re-intervention rates during follow-up. Significant between-group differences were noted for mean cardiopulmonary bypass time (93.2 ± 34.7 BIMA vs. 108.8 ± 40.7 LIMA min, P = 0.02) and for red blood cell transfusion (1.9 ± 1.9 vs. 4.3 ± 2.8 packed cells/patient, P < 0.001).

Conclusions: The performance of mainly arterial revascularization with BIMA grafting in patients 70 years or older is as safe as LIMA grafting, with the added advantage of being a better conduit than saphenous vein graft, requiring fewer blood transfusions, and shorter cardiopulmonary bypass time.

Backgound: The use of intraoperative transesophageal echocardiogram in patients with infective endocarditis is usually reserved for cases of inadequate preoperative testing or suspected extension to perivalvular tissue.

Objectives: To explore the impact of routine intraoperative TEE[1] in patients with infective endocarditis.

Methods: The impact of intraoperative TEE on the operative plan, anatomic-physiologic results, and hemodynamic assessment or de-airing was analyzed in 59 patients (38 males, 21 females, mean age 57.7 ± 16.8 years, range 20–82) operated for active infective endocarditis over 56 months.

Results: Immediate pre-pump echocardiography was available in 52 operations (86.7%), and changed the operative plan in 6 of them (11.5%). Immediate post-pump study was available in 59 patients (98.3%) and accounted for second pump-run in 6 (10.2%): perivalvular leak (3 cases), and immobilized leaflet, significant mitral regurgitation following vegetectomy, and failing right ventricle requiring addition of vein graft (1 case each). Prolonged de-airing was necessary in 6 patients (10.2%). In 5 patients (8.5%) the postoperative study aided in the evaluation and treatment of difficult weaning from the cardiopulmonary bypass pump. In 21 patients (35.6%) the application of intraoperative TEE affected at least one of the four pre-specified parameters.
Conclusions: Intraoperative TEE has an important role in surgery for infective endocarditis and should be routinely implemented

Background: Hyperglycemia is common among patients admitted to intensive care units, and carries the risk for complications and prolonged ICU[1] stay. With intensive insulin control of blood glucose, morbidity and mortality can be reduced.

Objectives: To determine whether intensive or conventional insulin control of blood glucose in hyperglycemic ICU patients correlated with the prognosis.

Methods: Following admission to the ICU, hyperglycemic patients were randomly assigned to a group treated intensively with insulin targeting glucose at 110–140 mg/dl, or to a conventional insulin therapy group, where glucose, upon exceeding 200 mg/dl, was controlled at 140–200 mg/dl. Rates of morbidity and mortality, hypoglycemic episodes, and insulin dosage were compared.

Results: In the 41 patients treated intensively with insulin the glucose level was 142 ± 14 mg/dl, as compared to 174 ± 20 mg/dl in the 48 patients on conventional insulin treatment. Both groups were similar in age, acute physiology and chronic health evaluation score. Morbidity was also similar, except for increased vascular damage in the conventional treatment group and slightly shorter ICU stay in the intensive therapy group. Both groups had similar in-ICU, in-hospital, and 28 day mortalities, and similar rates of hypoglycemic episodes. The daily dosage of insulin was significantly higher with the conventional treatment (P = 0.004).

Conclusions: Intensive insulin treatment did not affect the mortality or morbidity rates in ICU patients. The increased insulin dosage of conventional insulin treatment was attributable to the group's higher prevalence of diabetes. Future studies should address this bias and determine the optimal glucose target.  

Background: When encountering complaints of pain in the area of Achilles tendon with a suspected lesion, the clinician seldom reaches a precise diagnosis based only on X-ray and clinical examination. Ultrasonography is useful for evaluating the pathology and treatment.

Objectives: To assess the relative contribution of real-time intraoperative ultrasound examination and immediate postoperative ultrasound in patients with acute rupture of the Achilles tendon treated by percutaneous suture method. The combination of both procedures provides a unique advantage that could facilitate better results.

Methods: Ultrasound examination was used in 20 patients with acute rupture of the Achilles tendon who were treated surgically. Intraoperative as well as postoperative ultrasound examinations were performed in 5 patients whereas 15 patients underwent an immediate postoperative ultrasound.

Results: Ultrasound pathologies were found in all patients. Percutaneous surgical correction of ruptured Achilles tendon with accurate positioning of the foot using real-time sonography was successful in all the patients.

Conclusion: As in many other soft tissue lesions, ultrasonography is a useful tool for evaluating the pathology and for planning the surgical correction of ruptures in the Achilles tendon.

Background: Fractures of the femur in neonates are relatively uncommon. The infants feel pain and discomfort, causing parental distress, and the hospital stay is longer. Treatment of this specific fracture is problematic because of the small size of the baby.

Objectives: To review the results of the treatment of neonatal femoral fractures.

Methods: We retrospectively reviewed all neonatal fractures of the femur during a 12 year period. Thirteen fractures of the femur in 11 babies were treated with improvised Bryant skin traction of both legs. All the patients were re-examined after a mean follow-up period of 5.2 years.

Results: All fractures healed satisfactorily clinically and radiographically, with no residual deformity, no leg length discrepancy and no functional impairment.

Conclusions: Bryant’s traction for 2–3 weeks in hospital is a safe method for the treatment of femoral fractures in neonates, and the outcome is good.
 

Objectives: To evaluate the criteria used to select surgical versus medical management for SICH.

Methods: We retrospectively reviewed the files of 149 consecutive patients admitted with SICH[1] from January 2004 through January 2006 to our medical center. Their mean age was 66 (range 3–92 years), and 62% were male. SICH localization was lobar in 50% of patients, thalamus in 23%, basal ganglia in 15%, cerebellum in 13%, intraventricular in 6%, and pontine in 1%. Mean admission Glasgow Coma Score was 9 (range 3–15). Risk factors included hypertension in (74%), diabetes mellitus (34%), smoking (14%) and amyloid angiopathy (4%). Fifty percent of patients were on anticoagulant/antiplatelet therapy, including enoxaparin (3%), warfarin (7%), warfarin and aspirin (9%), or aspirin alone (34%).      

Results: Craniotomy was performed in 30% of patients, and ventriculostomy alone in 3%. Rebleed occurred in 9% of patients. Six months after the treatment 36% of operated patients were independent, 42% dependent, and 13% had died. At 6 months, 37% of non-operated patients were independent, 15% dependent, and 47% had died.

Conclusions: One-third of the SICH patients, notably those who were experiencing ongoing neurologic deterioration and had accessible hemorrhage, underwent craniotomy. The results are good, considering the inherent mortality and morbidity of SICH.

Background: The degree of left ventricular dysfunction determines the prognostic outcome of patients with acute myocardial infarction.

Objectives: To define the clinical, angiographic and procedural variables related to LV[1][1] dysfunction in patients with  with anterior wall AMI[1][2] referred for primary percutaneous coronary intervention.

Methods: The sample included 168 patients treated by primary PCI[1][3] for first anterior wall AMI. Clinical, demographic and medical data were collected prospectively into a computerized registry, and clinical outcome (death, reinfarction, major cardiovascular event) were evaluated during hospitalization and 30 days after discharge. Patients were divided into three groups by degree of LV dysfunction (mild, moderate, severe) and compared for clinical, angiographic and procedural variables.

Results: LV dysfunction was associated with pre-PCI renal failure (serum creatinine > 1.4 mg/dl), peripheral vascular disease, high peak creatine kinase level, longer door to balloon time, low TIMI flow grade before and after PCI, and use of an intraaortic balloon pump. On multivariate analysis adjusted for baseline differences, peak creatine kinase level (r = 0.3, P = 0.0001) and door to needle time (r = 0.2, P = 0.008) were the most significant independent predictors of moderate or severe LV dysfunction after anterior AMI.

Conclusion: Abnormal LV function after first anterior AMI can be predicted by door to balloon time and the size of the infarction as assessed by creatine kinase levels. Major efforts should be made to decrease the time to myocardial reperfusion.

Objectives: To determine whether reliable data could be obtained at lower cost.

Methods: The study sample consisted of 50 patients with mild to severe stable COPD]1[. All underwent pulmonary function test and the cardiopulmonary exercise test, 6 minute walk and 15 step exercise oximetry test as part of their regular follow-up visit. Functional capacity was graded according to each test separately and the functional capacities obtained were correlated.

Results: The results showed that most of the patients had severe COPD according to pulmonary function tests (mean forced expiratory volume in the first second 46.3 ± 19.9% of predicted value). There was a good correlation between the cardiopulmonary exercise test and the 6 minute walk functional capacity classes (r = 0.44, P = 0.0013). We did not find such correlation between the 15 step exercise oximetry test and the cardiopulmonary exercise test (r = 0.07, P = 0.64).

Conclusions: The study shows that the 6 minute walk is a reliable and accurate test in the evaluation of functional capacity in COPD patients.
