The use of balloon dilatation to treat native coarctation of the aorta is gaining acceptance among interventional pediatric cardiologists, but is still controversial. We describe our experience with this procedure in 21 children, mean age 5.6 years and mean weight 21.1 kg. Most had an additional congenital heart defect, most commonly a bicuspid aortic valve. 17 were asymptomatic, 3 had tachypnea and 1 infant had severe congestive heart failure and was ventilated. The mean systolic blood pressure was 129.7 mm Hg.

Balloon dilatation was successful in 90% (19), decreasing the mean maximal systolic gradient from 35.3 to 9 mm Hg (p<0.001), and increasing the narrowest area from 3.9 to 8.2 mm (p<0.001), with a mean balloon-to-coarctation width-ratio of 2.8. There were no complications. Of 15 who underwent repeat cardiac catheterization at a mean interval of 10.6 months, 2 had a maximal systolic gradient of more than 20 mm Hg. 1 of these underwent successful repeat angioplasty and the other, who also had a small aneurysm, underwent surgical repair successfully. 2 others had small aneurysms and they are being followed clinically.

All patients were seen again after a mean interval of 31 months. The mean systolic blood pressure was 104 mm Hg, significantly lower than before intervention (p<0.002). 1 had an increased pressure gradient between right arm and leg of 35 mm Hg at later follow-up, and repeat cardiac catheterization demonstrated a good result 13 months after the initial procedure. She is awaiting a third catheterization. Overall, 90% had good mid-term results.

Based on our experience and recent reports, balloon angioplasty is safe and effective in most children older than 7 months and should be considered a viable alternative to operation for discrete aortic coarctation. Further long-term evaluation is needed.

Hepatitis A is one of the most frequently reported notifiable infectious diseases in Israel. The annual incidence as reported is around 70/100,000. The physician or the diagnostic laboratory notifies the district health office of the Ministry of Health.

The purpose of this research was to evaluate the sensitivity of passive surveillance of hepatitis A morbidity among adults, 18 years and over. Methods included study of notifications to the Ministry of Health or hospitalizations of cases of hepatitis A and of positive laboratory tests results (IgM) for hepatitis A. We estimated the extent of under-reporting by 2 different methods of extrapolation.

Data based on passive surveillance among the adult population, between 1.1.1993-31.12.1994, comprised less than 1/5 of the actual number of cases. Physicians notified about 6.2% of their hepatitis A patients. 5.1% of the notifications to the district health office were sent twice or more, usually both by the physicians and labs.

The official data on hepatitis A morbidity, based on passive surveillance, are considerably underestimated. Physicians and public health officials should be aware that such data may not accurately reflect the magnitude of the risk or the amount of disease that can be prevented. Efforts should be made to improve this situation.

In recent years percutaneous closure of small and medium- sized patent arterial ducts has been achieved using occluding spring coils. We describe our experience in 93 patients with this tec, using a snare to facilitate the procedure in most. All patients had a clinically apparenpatent arterial duct and had undergone attempts at transcatheter closure at a mean age of 6.8 years. In 1, the duct was a residual lesion following surgical ligation, and in 5 it was a residual following attempted closure with the Rashkind double-umbrella. The mean narrowest diameter of the ducts was 2.1 mm.

In our 93 patients implantation was successful in 92 (99%), using 1 coil (82 patients), or 2 (10 patients), and in 1 by a combination of a double-umbrella device and an occluding spring coil.

The mean fluoroscopic screening time for the whole group was 22.8 minutes, which decreased to 16.8 minutes in the last 50 patients. The coil embolized in 7 patients, but was retrieved in 6 and the ducts were subsequently occluded with another coil. In 1 patient the coil was left in a distal small branch of the left pulmonary artery and the duct was successfully occluded with a double-umbrella.

Color-Doppler echocardiogram performed the morning after placement of the coils showed residual leaks in 18%. At mean follow-up of 24.6 months repeat imaging showed residual leaks in only 3 of these patients (3%).

We conclude that occlusion of small to medium-sized ducts using coils appears to be effective and is the treatment of choice. The use of a snare to hold and manipulate the coil as it is delivered improves control of the coil, the accuracy of its placement, as well as giving complete occlusion of the ducts.

Blockage of platelet glycoprotein IIb/IIIa receptor by Reopro c7E3 Fab-abciximab) has been shown to reduce markedly ischemic complications during and following elective and high-risk coronary intervention CI). Between July ’96 and February ’98, 120 consecutive patients (85 men and 34 women, aged 34-90 - mean 62) received Reopro (20 mg bolus, followed by 10 mg/min for 12-48 hours). 100 were treated with Reopro in the catheterization laboratory, in 76 as prophylactic treatment preceding high-risk CI and in 24 as bailout treatment for acute complications during CI. 20 additional patients were treated in the CCU for acute coronary syndromes, 17 of whom underwent CI 6-48 hours later.

Coronary angiography demonstrated multivessel disease in 66 (56%), and the target lesions were LAD - 77, RCA - 41, LCX - 22, SVG - 6, and 2 unprotected LMCA (total: 148 lesions dilated in 117 patients). Of the 117 CI, 44 were PTCA alone, and 73 included stenting.

Indications for prophylactic Reopro for high risk CI were: acute MI (48 hours), early post-MI angina, unstable AP, and/or complex anatomy with visible thrombus. In this high-risk population the overall success rate (open artery, no MI, discharged alive, no need for urgent re-vascularization) was 97% when Reopro was given prophylactically prior to CI. The success rate was lower (87.5%) when Reopro was given in bailout situations.

In 20 patients with acute coronary syndromes treated in the CCU while receiving maximal combined conventional therapy (including full-dose heparin), all symptoms and dynamic ischemic ECG changes disappeared within minutes following Reopro. 17 underwent successful CI during hospitalization and 3 were treated medically.

Reopro given prior to high risk CI was associated with a very low rate of complications. In a few cases with acute coronary syndromes, Reopro given in the CCU cases immediate relief of myocardial ischemia and reduced the need for urgent coronary intervention.

Isolated secundum atrial septal defect is one of the most common congenital heart defects. Surgical closure is the treatment of choice but is associated with a chest scar, some morbidity and a relatively long recovery and the use of cardiopulmonary bypass. Transcatheter closure of secundum atrial septal defect is therefor an attractive approach.

3 children, aged 5-10 years, underwent successful transcatheter closure of moderate to large central atrial septal defects with the Cardioseal device. The procedures were performed under x-ray and transesophageal echocardiographic guidance.

Our initial experience, and that of others, indicates that transcatheter occlusion of secundum atrial septal defects is safe and effective and can be an appropriate alternative in approximately 60% of patients.

Kimura's disease is a rare angiolymphoid proliferative disorder of soft tissue characterized by subcutaneous swelling and a predilection for the head and neck. There are usually enlarged regional lymph nodes, eosinophilia and elevated sedimentation rate and IgE levels. A 26-year-old women with subcutaneous masses in the submandibular area is reported. The diagnosis of Kimura's disease versus angiolymphoid hyperplasia is discussed.

Coronary artery bypass grafting is the treatment of choice for obstructive disease of the left main coronary artery. Its proximal location and easy accessibility make the left main artery an inviting target for percutaneous intervention, an approach contraindicated by the high associated risk. We describe 2 patients at high operative risk in whom the obstructed main coronary artery was successfully revascularized percutaneously. Coronary stenting and rotational ablation of calcified arteries are essential for successful outcome and minimize complications.

Health care workers are at continuous risk of hepatitis B infection. Currently recommended intramuscular vaccination confers immunity in only 85-90%. We examined the immunogenicity and safety of intradermal vaccination of hepatitis B vaccine in nonresponders. 400 hospital employees who had been immunized as recommended were screened for anti-HBs antibodies and 50 were found seronegative. Each received an intramuscular booster injection and antibody level was measured a month later. Excluded were 33 employees, including 24 late responders, 2 HbsAg carriers and 7 uncooperative employees. 17 employees (mean age 47.1 yrs) then received a series of 3 intradermal injections of Energix B, 0.25 ml in the forearm, 2-3 weeks apart. The mean number of previous intramuscular injections was 4.6±1.4 month later there was a mean titer of 315.4±347.0 miu/ml of antibody in 16/17 workers. Side effects were minimal. Intradermal injection of hepatitis B vaccine for nonresponders seems effective for inducing seroconversion. Its cost-effectiveness for the health care system warrants assessment.

Many studies have tried to explain why professionals experience difficulty when dealing with, and in treating efficiently situations connected with death. We studied levels of personal fear among physicians in general hospitals and addressed 2 questions: Does exposure to death on professional and personal levels, affect the level of the fear of personal death which physicians experience? Is there a relationship between personality variables, represented by the repression-sensitization dimension, and level of fear of personal death? A sample of 233 physicians from 22 general hospitals who specialized in oncology, internal medicine, surgery, psychiatry or pediatrics was studied. Each answered 4 questionnaires with regard to demographic information, fear of personal death, level of repression-sensitization and exposure to the death of relatives and significant others. There were no differences in level of fear of personal death of physicians according to specialization, but those who had been exposed to death on the personal level, feared less their own death. With respect to the personality variable, tendency to sensitization, it was found that those who were sensitized exhibited a higher level of the fear of their own death compared to those who were repressive. Of the various demographic variables examined (sex, level of religiouobservance, age, number of children, health, professional experience) it was found that those: with many years of professional experience, who were relatively older, who were nonobservant religiously and who were in good health, had lower levels of personal fear of death; gender was not a factor.

For the past several years, the hospitalization and care of complex nursing care patients (CNCP) has caused concern among organizers, funders and care-givers of the geriatric hospitalization system (GHS). To assist in improving efficiency of the GHS and to address the lack of comprehensive, empirical and up-to-date information on these patients, we conducted a survey to characterize CNCP, to assess their medical problems and to determine their prevalence among the patients in GHS. The survey was conducted in 1994 using a day census. Data were collected on the 2,319 patients in geriatric beds in all the general hospitals and geriatric hospitals in Israel on the day of the survey.

28% of the patients in the GHS were CNCP and a quarter of them (7% of all patients) suffered from more than 1 medical condition. Tube feeding was the most prevalent condition (13% of all patients), followed by terminal illness (9%), deep pressure sores (7%) and intravenous transfusion for more than 3 days (6%). The 80% of the CNCP were hospitalized in geriatric hospitals, primarily in geriatric rehabilitation wards. Their average length of stay was over a year. Internal medicine wards of general hospitals were the most frequent source of patient referral. The survey's findings raise issues related to the organization of care of CNCP. They may serve as a basis for the reorganization of the geriatric hospitalization system in order to improve efficiency and quality of care for the benefit of patients, their families and services providers.

Percutaneous endovascular techniques are well established procedures in the management of peripheral vascular disease and visceral arterial stenosis. They are now being adapted for use in the carotid artery as well. 8 patients with 9 extracranial carotid artery stenoses were successfully treated by percutaneous angioplasty, following which in 4 of them 5 stents were inserted. The stenotic lesions were situated in the proximal internal carotid artery and in its bifurcation and also in the common carotid artery. The indications for angioplasty in these patients were the same as for surgery. There were no major complications. 1 patient had transient hemiparesis lasting a few hours, and another had bradycardia following balloon dilatation in the region of the carotid body. Percutaneous endovascular treatment of carotid artery stenosis is becoming a safe, feasible alternative to surgery.
