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.

Islet cell antibodies (ICA) continue to serve as the basis of the principal serological test for definition of active autoimmunity of beta-cells. Its disadvantages are the need for human pancreatic tissue and difficulty in obtaining quantitative results. In the past decade biochemically-defined beta-cell antigens were described, leading to the development of sensitive and specific autoantibody assays, to predict insulin-dependent diabetes mellitus (IDDM). We examined the value of combined biochemically-based serological assays, such as autoantibodies to insulin (IAA), glutamic acid decarboxylase (GADA) and ICA512 (ICA512A) to replace the traditional ICA assay.

Blood samples of 114 newly diagnosed IDDM patients, aged 12‏5 yrs (range 2 months - 29 years) were tested for ICA (indirect immunofluorescence), IAA, GADA and ICA512A (radiobinding assay). The latter 2 assays were performed using recombinant human [35S]-labeled antigen produced by in vitro transcription/translation. We found that fewer sera scored positive for ICA and/or IAA (80.7%, 92/114) than for 1 or more of IAA, GAD, or ICA512 (88.6%, 101/114). We conclude that combined testing for IAA, GAD and ICA512 can replace the traditional ICA/IAA test to predict IDDM and is helpful in the differential diagnosis of insulin-dependent and noninsulin-dependent diabetes.

A 40-year-old woman attempted suicide by drinking methanol. Her visual acuity began to deteriorate 36 hours later and was found to be 6/60 in her right eye with no light perception in the left. No systemic manifestations other than the eye symptoms were found. In the following months visual acuity improved without specific therapy. 2 months following the methanol, visual acuity was 6/6 in the right eye and finger-counting at 1 meter in the left eye. There was pronounced optic atrophy in the left eye, as well as a central defect in the left visual field due tothe methanol toxicity.

Cyclic vomiting syndrome in children is a manifestation of various etiologies, including gastroenterological and renal disorders, central and autonomic nervous system abnormalities, as well as metabolic and endocrine dysfunction. Frequently no organic cause is found. Personality profiles of children with cyclic vomiting reveal perfectionism, competitiveness, and aggressive behavior. Vomiting attacks have been induced by anxiety and excitement in patients with cyclic vomiting. We describe an 8-year-old girl with cyclic vomiting, frequently associated with occipital headaches, photophobia or dizziness. Psychiatric evaluation indicated a generalized anxiety disorder.

Sudden death from asthma is rare but occurs in the young age group. We recently faced this rare situation, when 3 asthmatic children were dead on arrival at the local emergency room. All 3 had been treated with beta-2 agonist inhalation on a regular basis, without anti-inflammatory treatment. 2 of the children died while inhaling the beta-2 agonist. It is important that there be clear guidelines and full education about the management of asthma, during and between exacerbations, to prevent such deaths.

Results of chemotherapy with Taxol (paclitaxel) in 55 patients with recurrent breast and ovarian cancer were reviewed. Taxol was given as a 3-hour infusion, every 3 weeks, on an outpatient basis. There was complete or partial response in 8 patients (23%) with breast cancer and 10 (50%) with ovarian cancer. Performance status and previous response to adriamycin were important prognostic factors. Toxicity was manageable. Treatment had to be stopped for hypersensitivity reactions in only 2 patients. Taxol given in an ambulatory clinic is safe and effective.

Photodynamic therapy (PDT) is a noninvasive selective therapy for a specific group of skin tumors. 5-aminolevulinic acid 20% in a water-in-oil cream base was applied to the tumors as a photosensitizer and was followed after 12 hours by exposure to a high output light source emitting red (585-720 nm; 150 mW/cm²) and near infrared irradiation (1.25-1.6 mm; 50 mW/cm²) for 10-15 minutes (VersaLight, incoherent filtered light source). Complete responses were achieved after 1-3 treatments in 26/31 lesions of superficial or small nodular basal cell carcinoma (BCC) and 4/5 in superficial, squamous cell carcinoma (SCC) lesions. There was a patient with Bowen's disease of the penis. Follow-up was for 12-24 months. This noninvasive, nearly painless treatment gives excellent therapeutic and cosmetic results. Our data show its efficacy for certain subtypes of BCC, SCC and Bowen's disease. Further studies will determine the exact cure and recurrence rates with this modality and compare it to other modes of skin cancer therapy.

Progress in diagnostic radiology and pathology during the past decade has changed the approach to diagnosis of mediastinal masses. Diagnosis by CT-guided needle biopsy (CTNB) has replaced open biopsy and mediastinoscopy. CTNB of mediastinal masses is accurate, reliable and safe. It is done under local anesthesia, in ambulatory patients and is tolerated well. Between July 1987 and April 1997 we performed 67 biopsies in 63 patients aged 6-86 years; 33 were women (average age 40.8 years) and 30 men (average age 38.3 years). 57 of 67 biopsies were core biopsies for histologic examination and 10 were cytologic biopsies. In this report we concentrate on the 57 core biopsies. 41 of the biopsies were diagnostic; in 3 of them no evidence of malignancy was found. In 38 of the biopsies a tumor, malignant or benign, or an inflammatory process was diagnosed. In 24 of the biopsies the diagnosis was lymphoma. In 16 there was not enough material for diagnosis. We repeated the biopsy in 4 of the latter due to high suspicion of malignancy and reached a diagnosis in all 4 of them. In 6 the diagnosis was reached only by operation. The biopsies were from all compartments of the mediastinum. There were no complications such as pneumothorax or bleeding, except for 1 case of mild hemoptysis. In conclusion, CTNB of mediastinal lesions is accurate, safe and relatively cheap. In 72% a diagnosis was reached in the first attempt and a second attempt raised the diagnostic rate to 79%. We believe that CTNB should be the first step in tissue diagnosis of mediastinal masses, including those with a high suspicion of lymphoma.

There is inherited predisposition to breast and ovarian cancer in 5-10% of all women with these diseases. Germline mutations in BRCA1 and BRCA2 presumably account for most of the genetically susceptible individuals. We summarize 2 years of experience in counseling and testing for inherited predisposition to these cancers.

597 women (from 320 families) have been evaluated since August 1995. 242 were evaluated for inherited predisposition to breast and ovarian cancer. One-third had clear-cut evidence of familial background. 74 families were of Ashkenazi origin; the age range of breast cancer was 30-35, of ovarian cancer 40-45. In 80% of families other cancers were also noted in first degree family members, including lung, colon, and prostate cancer and leukemia.

Genetic testing revealed that 45% of affected and 25% of unaffected women were carriers of a mutation in BRCA1 or BRCA2: 67/90 185delAG (BRCA1), 12/90 6174delT (BRCA2), and 4/90 of 5382insC (BRCA1). In addition, a novel mutation in exon 11 of BRCA1 was detected, carried by 7/90 women. The experience gained in oncogenetic counseling and genetic testing for inherited cancer predisposition will eventually enable determining an optimal, rational therapeutic regimen in carriers of mutations.

Acute hyperparathyroidism is a rare and dangerous condition. It is supposed to result from transformation of a mild chronic form into an acute and stormy illness. The causes and the mechanism of such a transformation are usually unknown. A case of acute hyperparathyroidism is presented in which hemorrhage into a parathyroid adenoma was recognized and diagnosed as the immediate cause of the transformation from the mild long-standing form of the disease into the severe acute form.

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.

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.

The purpose of orthopedic joint implants is to improve joint movement. Within the past 30 years, biomechanical improvements affecting the life-span of the implants has brought a new type of problem: the biological response to debris from the implant material contributes greatly to aseptic loosening of the prosthesis. The process is mediated by osteotropic factors, cytokines released from mononuclear cells, and osteoblasts and osteoclasts in the bone-cement interface or bone-implant interface.

The skeletonized internal mammary artery (IMA) is longer, and its immediate spontaneous blood flow is greater than that of the pedicled IMA, thus providing increased versatility for complete, arterial myocardial revascularization without the use of saphenous vein grafts. From April 1996 to May 1997, 583 patients underwent coronary artery bypass grafting here and in 415 (71%) complete arterial revascularization was achieved using bilateral skeletonized IMA. The right gastroepiploic artery was used in 57 (13%); there were 329 males (79%) and 86 women (21%); average age was 64 (30-87) and 175 (36%) were older than 70; 131 (32%) were diabetics. Average number of grafts was 3.2 (range 2-6 grafts). At 30 days, 5 (1.2%) had died and there had been 6 perioperative infarcts (1.4%), 5 CVA's (1.2%), and 6 had sternal wound infections (1.4%). Up to 1-12 months of follow-up was achieved in 409 (99%). Late mortality was 1.4% (of which 3 were noncardiac). 394 (97%) were angina-free at latest follow-up. We conclude that arterial revascularization using bilateral skeletonized IMA is safe, as postoperative morbidity and mortality are low, even in old and diabetic patients.

Screening tests including mammograms for early detection of breast cancer are in the basket of services provided under the National Health Insurance Law. The law also defines the population groups entitled to mammograms, and sets the frequency of the test as once every 2 years. The aim of this study was to examine the screening rates for early detection of breast cancer at the inception of the law, in order to monitor future changes in performance rates, and identify the characteristics of those unlikely to undergo these tests, in order to promote the use of screening tests by them. This study is part of a comprehensive survey examining the effect of the National Health Insurance Law on the Israeli population.

The survey, carried out in the summer of 1995, included a sample of 1,400 Israeli residents aged 22 and over. To determine performance rates for clinical breast examinations a subgroup of 515 women aged 30 and over was sampled. To determine performance rates for mammograms, 173 women were aged 50-74 (the entitlement ages under the law), were sampled. 54% of women aged 30+ reported having had at least 1 clinical breast examination during their lifetime, and 56% of women aged 50-74 reported having had a mammogram during the past 2 years. Variables with an independent effect on the likelihood of having had a clinical breast examination by a physician during the past 2 years were: being over the age of 50, having at least 9 years of education, being a veteran resident of Israel (as opposed to a new immigrant), and being Jewish. Variables with an independent effect on the likelihood of having a mammogram during the past 2 years were: being a veteran resident of Israel, and having a high income צ which was found to have a borderline effect. The findings of the survey emphasize the importance of changing the behavior patterns of both women and physicians, informing women about their entitlement to the tests, and raising consciousness of the importance of having repeated clinical examinations by a physician, as well as mammograms.
