Over the past 15 years, percutaneous therapeutic cardiac catheterization has become increasingly important in the treatment of congenital heart disease. We describe our experience in 1000 such catheterizations between 1993-1997. 55% were in 1-12-year-olds; only 20% were in patients younger than 1 year old and 11.3% were in adults with congenital heart defects. In about 50% it was at least a second cardiac catheterization. Overall, there were 425 therapeutic cardiac catheterizations, increasing from 33% in the first 200 procedures, to 63% in the last 200.

We performed 30 different types of therapeutic catheterizations: 23.3% were valvular dilations, 21.4% vessel angioplasties, 36.9% closure procedures, 9.2% electrophysiological procedures, and 9.2% miscellaneous. In 31.3% of therapeutic catheterizations we used 12 new procedures. Minor complications occurred in 8.5% and major in 0.6%; most complications were successfully treated or were self-limited and there was no residual damage.

In this report the current role of each type of major catheterization is discussed on the basis of our experience. Further development of technology for lesions not amenable to currently available transcatheter methods, and longer follow-up for current techniques will consolidate the role of therapeutic cardiac catheterization in congenital heart disease.

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.

Brucellosis Presenting as Acute Abdomen

Usually symptoms of brucellosis are nonspecific and characterized by a wide range of complaints. Although the disease in Israel is almost exclusively food borne (caused by Brucella melitensis in unpasteurized goat milk products) so the main route of infection is the gastrointestinal tract, but gastrointestinal complications are rare, and only sporadic cases of ileitis or colitis have been described.

We present a 43-year-old woman with an acute abdomen, probably due to diverticulitis. It was diagnosed only after blood cultures were positive for Brucella melitensis. We believe that its protean manifestations should be consin addition to the other bizarre presentations of this disease, important in our region.

The Israel Teratogen Information Service: A 10-Year Report

The Israel Teratogen Information Service (TIS) was established 10 years ago with the help of the Ministry of Health and the Hebrew University-Hadassah Medical School. During these 10 years we have had 20,631 calls. We describe the results of our experience in counseling.

There was a gradual increase in the number of calls, which in 1997 reached 4,447. Most calls (84.5%) were during pregnancy, while 12% were prior to pregnancy. In 75.7% the calls were due to drug exposure during pregnancy; 10.9% were due to exposure to X-rays; there was maternal infection in 6.6% and in 5% immunization during pregnancy. The callers were: physicians in 46.6%, nurses 18.9%, pregnant women 39.5%, and 4.8% others.

In 76.6% there was no additional risk to the embryo or fetus and in 17.4% there was a small additional risk of less than 1%; a significant additional risk to the fetus was expected in only 6%. In 3625 pregnant women with known outcome there were 8.9% spontaneous and 9.2% induced abortions. Of the 2968 live-born children, 2.3% were malformed, a rate similar to that among controls.

The information provided by the TIS alleviated the fears most pregnant women have, and reduced unnecessary terminations of pregnancy planned because of unjustified fear of the teratogenic effects of agents to which women were exposed. It reduced the number of children born with congenital anomalies, since pregnancies were interrupted whenever there was a high risk for congenital anomalies.

Ebstein anomaly is a rare congenital disease which affects location, structure and mobility of the tricuspid valve, and right atrium and ventricle. Although most cases are sporadic, familial occurrence has been reported. We report 2 brothers born with Ebstein anomaly. The parents were first degree cousins and there were 8 other children. 2 daughters were born with other congenital heart anomalies, 1 with ventricular septal defect and the other with severe pulmonary artery stenosis. We suggest that in some families, Ebstein anomaly is an autosomal dominant disease with different expression in the sexes.

Patients' opinions of the role of the primary care physician were studied. The study population consisted of Hebrew-speaking members of the Clalit Sick Fund, aged 18+, who visited primary care and specialty clinics. Interviews took place during January-March 1995 in the Emek and Jerusalem, and during August-October 1995 in Beer Sheba. A total of 2,734 interviews were conducted, and the response rate was 88%. 64% of the respondents preferred the primary care physician as the first address for most problems occurring during the day. Multivariate analysis revealed that the variables predicting this preference were: being over age 45, having completed less than 12 years of schooling, being satisfied with the physician, and when a child's illness was involved. Whether the physician was a specialist had only a marginal effect. The findings also show that among those who did go directly to a specialist for the current visit, 49% would still prefer the primary care physician to be the first address for most problems. However, half of the respondents initiated the current visit to the specialty clinic themselves. The findings also showed that a preference for the primary care physician to be the first address had an independent and statistically significant effect on the following aspects of service consumption: taking the initiative to go to a specialist, the intention to return to the primary care physician or to the specialist for continuing care, and the patient's belief that referral to a specialist was needed. The findings of the study may be of assistance to policy-makers on the national level and to sick funds in planning the role of the primary care physician, so that it corresponds, on the one hand, to the needs of the sick funds and the economic constraints in the health system, and on the other, to the preferences of the patient.

Several conditions, considered as inborn errors of metabolism, involve severe deficiencies in carnitine in both plasma and muscle. In the absence of evidence suggesting primary carnitine deficiency due to a biosynthetic enzymatic defect in the liver, the various diseases with carnitine deficiency are related to genetic defects in organic acid metabolism leading to blocked mitochondrial b oxidation. We describe a 4.5-year-old boy and 2 female infants with glutaric aciduria type I, isovaleric acidemia, and long-chain acid dehydrogenase deficiency, in whom severe carnitine deficiency was apparent. In all 3, long-term carnitine treatment proved to be vital and eliminated most of the symptoms.

Q Fever Endocarditis and Bicuspid Aortic Valve

Q fever is caused by the rickettsia Coxiella burnetti, an obligate intracellular bacterium acquired by inhalation of infected dust from subclinically infected animals. Q fever may be acute or chronic; the chronic form mostly presents as endocarditis. Immunocompromised states and underlying heart disease are the most important risk factors. Usually the symptoms of Q fever endocarditis are nonspecific and diagnosis is often established very late. New criteria for diagnosis include a single blood culture positive for Coxiella burnetti, positive Q fever serology and characteristic echocardiographic studies. We describe a 49-year-old man with bicuspid aortic valve admitted with fever, weight loss and a new heart murmur. The diagnosis of Q fever endocarditis was established by positive Q fever serology, and an echocardiogram showing vegetations and valvular dysfunction. This case suggests that Q fever endocarditis should be considered in patients with "sterile" endocarditis.

Diarrhea is still a major cause of morbidity and mortality among children in developing countries. The Bedouin population of southern Israel is in transition from a nomadic to a settled life-style. We examined maternal knowledge and reported behavior when their children had diarrhea. Mothers defined diarrhea as the passing of 4-5 stools per day. The most frequent signs of the illness were an increased number of watery stools with changes in either color or form. The most frequent symptom that prompted mothers to seek medical aid was blood in the stool. All mothers reported increasing fluid intake in their children during diarrhea, and most reported giving herbal tea. About half of the women avoided milk products and used special for the treatment of diarrhea. A quarter of the women reported stopping or decreasing the frequency of breast feeding during diarrhea. Reported cessation of breast feeding during diarrhea was associated with changing to special foods, and failure to note the onset of diarrhea or to recognize signs of dehydration. The withdrawal of breast feeding during episodes of illness and diarrhea is related to lack of knowledge regarding diarrhea. These data indicate that even in this population, with free access to preventive and curative medical care, there should be greater efforts to educate mothers to detect diarrheal disease and to maintain breast feeding during the diarrhea.

Diarrheal diseases weigh heavily on the health of children, especially in developing countries, but also impose burdens on health care services worldwide. This study was performed to determine whether patterns of referrals in the Negev to the pediatric emergency room (PER) for diarrhea differ between the Jewish and Bedouin populations of the Negev, and the extent of the burden imposed on the PER and in-hospital services in the Negev. Characteristics of referrals and hospitalizations were examined from March 1994 to February 1995. Of the 27,834 referrals to the PER for children under 16, 2518 (9%) had diarrhea and there were 5,169 hospital admissions, 701 (13.6%). The annual rates of referral were 146 per 10,000 in Jews and 225 in Bedouin, giving an odds ratio (OR) of 1.5 (p<0.001). for Bedouin. The rates of hospitalization were 23 per 10,000 in Jews and 99 in Bedouin (OR 4.4, p<0.001). 1380 (54.8%) of the PER referrals were of infants under a year of age. For hospitalization, the annual rates were 164 per 10,000 in Jews and 756 in Bedouins (OR 4.9, p<0.001). During June to August referrals and hospitalizations for diarrhea were significantly higher, and from December to February significantly lower than during the remaining months. These differences arise from the marked seasonal pattern in the Bedouin population, whereas in the Jewish population there was no seasonal variation. Even in the 90's the burden on health services in the Negev as a result of diarrheal illness is considerable and the Bedouin population still contributes to that burden disproportionately. There is need both to reduce the gap in referrals and hospitalization between the populations, as well as to reduce the rates, using currently available means such as education, while developing new technologies, such as vaccines.

Between 1993-1996, 200 pediatric flexible bronchoscopies were performed. Indications were: chronic cough (158 children), persistent pulmonary infiltrates (89), recurrent stridor (28), suspected tracheobronchial foreign body (20), suspected tuberculosis (17) and hemoptysis (3). Some children had more than 1 indication. 124 patients were boys (mean 4.18+2.86 years; range 1 month-15 years) and 76 were girls (mean 4.39+2.7 years; range 4 months-15 years). The procedure included direct vision recorded by video-camera and broncho-alveolar lavage; the lavage fluid was sent for culture, Gram and Ziehl-Nielsen stains and for cytology. There were a few minor side effects: mild stridor which resolved within a few hours (10 children) and transient fever (3). This simple, flexible instrument was effective and helpful in the diagnosis and treatment of children with respiratory symptoms in a secondary hospital facility.
