Results of laboratory tests ordered during a primary care encounter may reveal findings of abnormal liver function tests, including elevated liver enzymes, hyperbilirubinemia, hypoalbuminemia or abnormal coagulation tests. The object of this study was to describe the spectrum of these liver function test (LFT) abnormalities in primary care.

Results of all laboratory tests ordered during 10 months in an urban primary care clinic were retrospectively reviewed and the medical charts of patients with abnormal LFTs were studied. In 217/1088 (20%) of the tests at least 1 LFT abnormality was found in 156 patients. New diagnoses were made in 104 patients. The main diagnostic groups were: non-alcoholic fatty liver changes, Gilbert's disease, acute infectious hepatitis, alcoholic liver disease and cirrhosis and hepatotoxic drug injury. In 60 patients the physician classified the abnormality as negligible and not associated with significant disease. However, an abnormal test that had been ordered for evaluation of a specific complaint, was indeed likely to represent significant disease (X²=29.5, p<0.001). We conclude that finding abnormalities in liver function tests is common in the primary care clinic but does not often indicate significant liver disease.

We review various theories of the pathogenetic mechanisms of steroid-induced and essential hypertension. We investigated the possibility that a pathogenetic mechanism leading to glucocorticoid (GC)-induced hypertension or to mineralocorticoid (MC)-induced hypertension, or both, may be of critical importance in primary hypertension. We studied plasma levels of corticosterone (BK) and aldosterone (Aldo), and their concentrations in arterial and renal tissues of spontaneously hypertensive rats (SHR), a model of primary hypertension, and in the antecedent strain WKY rats as a normotensive control. Plasma levels of BK and Aldo were found to be normal and identical in SHRs and WKYs. Tissue (intracellular) levels of BK were more than double in SHRs than in WKYs. Subsequently we examined the activity of 11b-hydroxy steroid dehydrogenase (11-HSD) in both aortic and renal tissues of SHRs and WKYs. 11-HSD converts BK to the corresponding 11-keto compound, 11-dehydro-corticosterone (cpd.AK), which is inactive, in view of its inability to bind to the MC receptors (and also to the GC receptors). BK, the main glucocorticoid in the rat, as well as cortisol, have high affinity for the MC-receptor (MR). Normally BK or cortisol are present in 10²-10³ times greater concentrations than Aldo in tissues possessing MR. The enzyme 11-HSD deactivates BK (or cortisol), thus protecting MC-receptors in the MC target tissues from being activated by GC. When we examined arterial and renal tissue activities of 11-HSD in SHRs, the activity of 11-HSD was only one-third that found in the WKY rats. This explained higher levels of BK in the tissues of SHR, and suggested that decreased activity of 11-HSD is a pathogenetic factor for hypertension in SHRs.

Thus, in a model of primary hypertension such as SHR, decreased activity of 11-HSD in the target tissues of MC appears to lead to glucocorticoid-induced mineralocorticoid hypertension.

Cryosurgery is an old technique which is being used for hepatic tumors as an adjuvant to hepatic resection. We recently treated 7 patients with multiple malignant liver tumors, 5 of whom had colorectal metastases, 1 carcinoid metastases, and 1 multiple hepatic lesions of hepatocellular carcinoma. 6 underwent combined liver resection and cryoablation of lesions in the remaining liver. In the 7th patient, only cryoablation was performed because hepatic resection was rejected and there was an extrahepatic metastasis. The advantages of this treatment are removal or destruction of all liver lesions found by any method, including intraoperative ultrasound examination, maximal preservation of normal liver parenchyma and that it is curative in patients inoperable by standard criteria.

A 15-year-old girl, who had been treated with minocyclin for acne for 2 months, was admitted for investigation of headache, nausea and papilledema. A space-occupying lesion was ruled out by computerized brain tomography. The diagnosis of benign intracranial pressure (pseudo-tumor cerebri) was made because of elevated cerebrospinal fluid pressure with normal biochemistry and cytology. Tetracyclines, especially minocyclin, commonly used for treating acne in adolescents, can cause benign intracranial pressure.

Polyunsaturated fatty acids (PUFA) are vital for the normal development of the brain and the eye retina in infancy. Breast milk contains significant amounts of PUFA, and compensates for their low production in infancy. Only recently a few companies with worldwide product distribution have started to enrich infant formula with PUFA. We evaluated the safety and clinical efficacy of a locally made PUFA-enriched infant formula, produced for the first time in Israel.

50 normal, full term infants participated in a prospective, randomized double-blind study. Half received a regular whey-predominant infant formula (Materna Plus), and the other half a PUFA-enriched formula (Materna Premium), both produced in Israel, for 30 days. Evaluation included physical examination, growth parameters, stool analysis, daily parental questionnaires regarding infant behavior and defecation, and developmental assessment.

There were no significant differences on comparing growth parameters, infant behavior, attacks of restlessness, gas severity, or stool characteristics in the 2 groups. There were no side effects or abnormal stool findings in either group, and no differences in developmental assessment at 3 months of age.

We conclude that the locally-produced PUFA-enriched infant formula is safe and clinically efficient. We assume that the lack of any effect on developmental indices is due to the relatively short exposure to the PUFA-enriched diet. Nevertheless, based on the recent literature, there is no doubt that PUFA supplementation isvital in improving infant brain and eye development.

Emergency Stenting for Acute Left Main Coronary Artery Closure during Cardiac Catheterization

Alberto Hendler, Oren Agranat

Catheterization Laboratory, Rama Marpeh Hospital, Petah Tikva

We report a case of acute closure of the left main coronary artery, a rare complication of diagnostic cardiac catheterization, treated by emergency stenting prior to aorto-coronary by-pass surgery. We suggest encroachment of the Judkins catheter into a calcified left main ostium, with dissection and acute thrombosis of this segment, as the possible mechanism.

Clinically, the patient's condition deteriorated to cardiogenic shock and loss of consciousness. Remarkably, there was no angiographic evidence of significant left main coronary artery disease, besides the presence of calcification in the proximal part of the left coronary system and ventricularization of coronary pressure at the time of engagement. We chose to slide quickly the angioplasty guidewire through the left main coronary artery, which allowed prompt mechanical recanalization and rapid restoration of coronary flow, with dramatic clinical and hemodynamic improvement. This relatively simple procedure allowed stenting the left main artery after brief predilation, and the patient came to by-pass surgery in excellent condition. The rationale for surgery in this case was the need for complete coronary revascularization because of significant 3-vessel coronary artery disease.

Our experience with living-related liver transplantation is described. In 2 boys and 1 girl, aged 4-4.5 years with acute, fulminating hepatitis A, the presence of very severe jaundice (bilirubin levels > 18 mg%) associated with severe coagulopathy (INR>10) and encephalopathy indicated the need for urgent liver transplantation. In all 3 cases the left lateral hepatic segment of a matched blood type parent was transplanted. None of the donors suffered a serious complication postoperatively and all returned to full activity in 6-16 weeks. The post-transplantation course was uneventful in 1 child, but in the other 2 there was hepatic arterial thrombosis in 1 at 1 day and in the other at 8 days post-transplantation. Early detection of arterial thrombosis by Doppler sonography permitted salvage of the 2 hepatic grafts after thrombectomy and re-anastomosis. In 1 of these 2 children an anastomotic biliary stricture was found 2 months after transplantation. It was corrected at surgery and a percutaneous stent was inserted. All 3 children are alive with normal graft function at 2, 7 and 8 months post-transplantation, respectively. This initial experience indicates that living-related liver transplantation is feasible in Israel. The technique might help to solve our severe organ shortage for children awaiting liver transplantation.

This study compares Israeli primary care physicians with those of European countries. In Israel a larger proportion of those in primary care are women. The Israeli physicians see many patients a day, but almost never make home visits. They also report for work the fewest hours a day, but spend 21 hours a month in continuous medical education. (more than Europeans?) The Israeli primary care physician scores high in screening for breast cancer and blood cholesterol level, but very low in the fields of minor surgery and alcohol and smoking prevention, contraception, nutrition counseling and normal pregnancy follow-up. Residency training and education may be inadequate, and more emphasis has to be put on the health system and recognizing environmental influences.

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.

A 48-year-old man presented with recurrent syncope which was preceded by facial edema and difficulty in breathing. Physical examination, laboratory tests, abdominal CT and bone scan were all within normal limits. Bone marrow biopsy was consistent with mastocytosis. Systemic mastocytosis consists of a spectrum of disorders characterized by aberrant proliferation of tissue mast cells, and are mainly related to mast cell mediator release.

In the past 10 years there has been a growing preference for early, complete correction of congenital heart disease. The first year of operation of this cardiac unit is described. 216 operations were performed: 15% in the neonatal age group and 35% in the newborn to l-year-old groups; 2% were palliative procedures. Mortality was 4.9%. Average stay in the ICU was 3.2  days, with a median of 2.25. Average length of ventilation was 35 hours, with a median of 17.5. Complications were: diaphragm paralysis in 13 (6%), 2/3 of which were recurrent operations; in 2 patients (0.9%) we had to plicate the diaphragm. There was severe neurological damage in 2, which deteriorated to brain death in 1. There was peripheral, reversible neurological damage in 4 (1.8%), and acute renal failure in 3%, with half of them requiring dialysis. 75% of these children died and there was superficial infection in 4.1%, deep wound infection in 1.3%, bacteremia in 4.1%, superior vena cava syndrome in 3 (1.3%) and chylothorax in 2 of them (0.9%). 1 patient (0.45%) required a ventricle-peritoneal shunt after acute viral meningitis. We are encouraged by our results to offer early complete correction to all children with congenital heart disease.

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.

We evaluated the efficacy of ciprofloxacin eardrops compared to tobramycin and to a placebo in the treatment of chronic suppurative otitis media. 60 ears were randomly assigned to treatment for 3 weeks with ciprofloxacin, tobramycin or placebo eardrops. The organism most commonly isolated from the ear discharge was Pseudomonas aeruginosa. The clinical responses were 78.9% and 72.2%, respectively, in the ciprofloxacin and tobramycin groups, while it was only 41.2% in the placebo group. Treatment with ciprofloxacin eardrops seemed to be at least as efficient as treatment with tobramycin. Considering the lack of ototoxicity of ciprofloxacin, this treatment may be best for chronic otitis media.

Subclavian vein thrombosis accounts for approximately 1-2% of recorded deep venous thromboses. It may be primary or secondary, and insertion of a central venous catheter is the most common cause of secondary subclavian vein thrombosis. Traumas, anatomic abnormalities and carcinoma are important additional risk factors for secondary thrombosis. Primary thrombosis of the subclavian veins is known as Paget-Schroetter syndrome. New criteria for its diagnosis include a history of increased upper extremity use prior to onset of symptoms, the presence of a venographically demonstrated thrombus and absence of any definable causes. We describe a 42-year-old woman with a history of intensive physical exertion admitted with swelling, pain and difficulty moving her arm. The diagnosis of primary subclavian vein thrombosis was established from the history of physical effort, results of Doppler ultrasound, and exclusion of other causes of subclavian vein thrombosis. This case suggests that primary subclavian vein thrombosis should be considered in young patients with subclavian vein thrombosis after exclusion of secondary disease.

Preliminary Experience with Laparoscopic Repair of Inguinal Hernias

During 1992-1996 we performed 163 laparoscopic hernia repairs in 100 men and 2 women. The mean age was 50.6; and in 61 the operation was bilateral. 66 were by transabdominal preperitoneal approach and 36 btotal extra-peritoneal approach. There were only a few minor complications and total recurrence rate was only 4.3%, partly attributable to our learning curve. Laparoscopic inguinal herniorrhaphy reduces postoperative incisional and muscular pain and causes less disruption in the postoperative period than open repair. Return to normal activity and work is faster for laparoscopic than for open repair, but operating room costs are higher (time and equipment). However, economic advantages for the national economy should be considered.
