Prevalence of melanocytic nevi and freckles in young Israeli males. Correlation with melanoma incidence in Jewish migrants: demographic and host factors.
The role of host and environmental factors in the pathogenesis of multiple melanocytic nevi, atypical nevi, and freckles was studied in 1989 in a random sample of 3,040 Israeli males aged 17 years. Multiple melanocytic nevi were significantly associated with family history of melanoma or multiple melanocytic nevi (odds ratio (OR) = 15.0), fair or lightly pigmented skin color (OR = 2.7 and 2.3, respectively), and affiliation to the high or heterogenous melanoma risk group, determined by the incidence rates of melanoma in Jewish migrants from corresponding origin (OR = 3.1 and 2.1, respectively). An environment-related effect may account for the increased multiple melanocytic nevi risk among second- (OR = 8.2) compared with first-generation, native-born recruits (OR = 3.0) from the high melanoma risk group whose families had been living in Israel the longest. Atypical nevi were associated with fair (OR = 6.1) and lightly pigmented (OR = 3.5) skin color, high and moderate sunburn susceptibility (OR = 4.7 and 2.5, respectively), and family history of melanoma or multiple melanocytic nevi (OR = 4.7). Freckles were significantly associated with sun-sensitive phenotype, family history of melanoma or multiple melanocytic nevi (OR = 1.5). Conservative (OR = 1.9) or nonreligious status (OR = 1.9), and high (OR = 2.4) or heterogenous melanoma risk groups (OR = 1.8). These findings indicate that environmental factors may modify the occurrence of multiple melanocytic nevi and freckles in genetically susceptible ethnic groups.

Induction of labor with use of a Foley catheter and extraamniotic corticosteroids.
OBJECTIVE: Our purpose was to examine the hypothesis that corticosteroids, when administered extraamniotically, can enhance the labor process and reduce the induction-to-delivery interval. STUDY DESIGN: A double-blind, randomized study was conducted on 98 women with a gestational age of 36 to 42 weeks, an unfavorable cervix, and medical indications for delivery, who were assigned to receive either 20 mg of dexamethasone in saline solution (study group, n = 50) or saline solution only (control group, n = 48) administered extraamniotically through an intracervical inflated Foley balloon catheter. The net effect of steroids was assessed with use of multivariant logistic regression analysis. RESULTS: The mean time intervals between induction of labor to the active phase and between induction of labor to delivery were significantly shorter in the study group compared with those of the control group (7.8 +/- 3.1 hours vs 9.9 +/- 3.9 hours, p < 0.03, 11.9 +/- 3.0 hours vs 14.5 +/- 4.8 hours, p < 0.01, respectively). Those not receiving steroids were at a 3.2 higher risk of having a longer time interval of induction to delivery (95% confidence interval 1.1 to 9.5). The general success rate in achieving vaginal delivery was, however, similar between the groups. CONCLUSIONS: Induction of labor with use of an intracervical Foley balloon catheter and extraamniotic corticosteroids reduces the time interval from induction of labor to delivery. This may indicate a possible role for corticosteroids in the parturition process.

Height and social class in male adolescents from different ethnic backgrounds in Israel.
The relationship between height and social class, independent of the effect of ethnic background was examined. This is a population-based study of 17-year-old israeli-born Jewish males born between 1966-1969 who underwent routine physical examination prior to army recruitment. Inductees descending from 9 ethnic backgrounds-Germany, Hungary, India, Morocco, Poland, Romania, Russia, Yemen and at least 3rd-generation israeli-born were used for this analysis. Anthropometric data was abstracted from the computerized induction examination; socioeconomic status (SES) was assigned according to the residence of each recruit. Statistical analysis included analysis of variance and chi square test for linear trend. Mean height of the total (reference) group was 173.7 cm, ranging from 172.0 cm in the lowest SES level to 175.1 cm in the highest level. The proportion of individuals above the 85th percentile of height of the reference group, increased linearly from 8.7% (lowest SES) to 18.5% (highest SES) (p < 0.01). The mean height of recruits differed considerably among ethnic groups in each SES level and ranged from 170.8 cm (Yemenites) to 175.4 cm (Russian and Romanian) in the total group. In each ethnic group, height differences between extreme levels of SES were observed ranging from 2.3 cm (Morocco) to 4.3 cm (Russia). We conclude that height among 17-year old israeli-born males is positively associated with SES after controlling for ethnicity.

Outcome of twin pregnancies reduced from triplets compared with nonreduced twin gestations.
OBJECTIVE: To compare the outcome of triplet pregnancies reduced to twins who reached 24 weeks' gestation with the outcome of twin pregnancies managed in the same perinatal department. METHODS: The study group included 43 triplet pregnancies reduced to twins who reached 24 weeks' gestation and were delivered between January 1989 and December 1993. The complications and outcomes of these pregnancies were compared with all 134 bichorionic twin pregnancies delivered during 1993. RESULTS: In general, the outcome of triplet pregnancies reduced to twins was not significantly different from that of twin pregnancies. Both pregnancy-induced hypertension and premature contractions were similar in the two groups. The higher incidence of premature rupture of membranes (PROM) in the reduced cases compared with nonintervention twins (18.6 versus 8.2%) was of borderline significance (relative risk [RR] 2.27, 95% confidence interval [CI] 0.98-5.27). Although premature delivery occurred in 30% of patients in both groups, 20.9% of patients in the reduction group delivered before 35 weeks' gestation, compared with 10.4% in the nonintervention group (RR 2.0, 95% CI 0.93-4.30). The mean gestational age was similar in the two groups, as was the risk of low birth weight and respiratory disorders. Differences in the proportion of patients with PROM, low gestation duration, and very low birth weight, although not quite statistically significant, are probably because of the relatively small numbers and, hence, of low power (50-55%), but may be of clinical importance. CONCLUSION: The outcome of triplet pregnancies reduced to twins did not differ substantially from that of nonreduced twin pregnancies.

The effect of estrogen replacement therapy on zinc in serum and urine.
OBJECTIVE: To ascertain the influence of estrogen replacement therapy (ERT) on blood and urinary zinc in postmenopausal women. METHODS: Thirty-seven postmenopausal women aged 53.2 +/- 3.7 years were examined. All were treated with conjugated estrogens 0.625 mg and medroxyprogesterone acetate 5 mg. Zinc, magnesium, calcium, phosphate, and alkaline phosphatase levels in blood were measured before and after 6 and 12 months of treatment. Urinary excretion of zinc, magnesium, calcium, phosphate, and hydroxyproline were evaluated before and after 3, 6, and 12 months of therapy. Bone mineral density was examined before treatment and after 1.7 +/- 0.3 years of ERT. Subjects were classified by 1) initial bone mineral density values (osteoporotics less than 0.850 g/cm2) and 2) zinc excretion as elevated (greater than 600 micrograms/g creatinine). RESULTS: At baseline, the values of most markers of bone turnover were higher in the osteoporotic women (Hotelling test, P = .06). After 1 year of treatment, a higher decrease of most indices was observed in the osteoporotic patients, and no statistical difference was found between the osteoporotic and the normal groups (Hotelling test, P = .31). A consistent negative association was observed between changes in bone mineral density and urinary zinc excretion in the osteoporosis group. Estrogen replacement therapy reduced excretion of zinc, magnesium, and hydroxyproline in the elevated zinc excretion group. Zinc excretion decreased 35% after 3 months and 26% after 1 year of treatment. The serum tests, with the exception of alkaline phosphatase, showed only negligible changes during ERT. CONCLUSION: A significant decrease in zinc excretion was observed after 3 months of ERT. This change was more pronounced in women with osteoporosis and elevated zinc excretion. Because zinc excretion is almost uninfluenced by variation in diet, it may be used as an additional marker of changes in bone metabolism.

Second-trimester serum fluorescence polarization in patients who subsequently develop pregnancy-induced hypertension.
To determine whether the midtrimester serum lipid profile, as expressed by fluorescence polarization (FP) values, is decreased in patients who subsequently develop pregnancy-induced hypertension (PIH). Stored serum samples of normotensive patients who had undergone midtrimester biochemical screening for Down's syndrome were used in this case-control study. Forty patients who subsequently developed PIH comprised the study group, and were divided into subgroups with proteinuric PIH (P-PIH, n = 18) and those with nonproteinuric PIH (NP-PIH, n = 22). Sixty randomly selected patients who remained normotensive throughout pregnancy comprised the control. Serum total cholesterol (CL) and triglycerides (TG) were determined using enzymatic colorimetric kits. FP values were determined by optical microviscosimeter. Both study subgroups had significantly lower FP values and higher TG concentrations than the control group. Total CL concentrations were slightly higher in the P-PIH subgroup. There were no differences in mean. Total CL or TG concentrations or mean FP values were found between those patients who developed mild and severe PIH. Using FP value cutoff points of 0.250, 0.245, and 0.240 sensitivity was 95%, 90%, and 78%, respectively, in detecting patients who subsequently developed PIH. Midtrimester serum FP values may have some predictive value for the development of P- and NP-PIH.

A controlled intervention in reduction of redundant hospital days.
BACKGROUND: Inappropriate use of hospital services, in the form of unjustified hospital stay days (HSD), constitutes a major burden on a health budget. Reduction of unjustified HSD was achieved in a medical ward in a previous intervention study. METHODS: A controlled intervention aimed at reducing unjustified hospital stay was performed on 155 paediatric inpatients and 248 controls, by applying pre-set criteria for hospitalization and comparing to results in previous studies. RESULTS: Unjustified stay was decreased from 32.6% to 14.8% on the study ward, and from 25.7% to 19.3% on the control ward. The children on both wards did not differ significantly in rates of subsequent out of hospital mortality, re-admission, and the subjective evaluation of health by their parents one month following discharge. CONCLUSIONS: This study demonstrates that despite the fact that the per cent of unjustified HSD on a paediatric wars is much lower than on medicine or surgery, a significant reduction in unjustified stay can be achieved by intervention programme.

Relationship between morbidity and extreme values of body mass index in adolescents.
BACKGROUND: Although the association between overweight and cardiovascular risk factors is well documented in cross-sectional and longitudinal studies, reports of adolescent morbidity associated with underweight in industrialized countries are rare. METHODS: This population-based study includes approximately 110,000 17 year old Israeli Jewish males who underwent routine physical examination at army induction centres. Computerized data tapes include overall health profiles, specification of physical and mental conditions, and height and weight measurements. Medically significant conditions are those with sufficient severity to preclude service in a combat unit. RESULTS: Functional limitation is more prevalent at both extremes of the body mass index (BMI) distribution: 149.5/1000 among severely underweight individuals and 164.3/1000 among severely overweight subjects. Overweight was associated with hypertension (14.9/1000 among the severely overweight), as well as joint conditions of the lower extremities, mainly hip, ankle and knee disorders. Functional disorders associated with underweight are bronchial and lung conditions, including asthma (14.2 and 18.9/1000 in the mildly and severely underweight), scoliosis, intestinal conditions and emotional disorders (mainly neurosis). CONCLUSIONS: Both under- and overweight are associated with morbidity at age 17. Intervention programmes should begin at an early age.

Glaucoma and visual outcome in central retinal vein occlusion.
Glaucoma is a recognized risk factor for central retinal vein occlusion. The authors retrospectively reviewed charts of fifty patients with central vein occlusion examined over a 5-year period. The visual outcome and clinical characteristics of eyes with and without glaucoma were compared. There were 32 eyes without glaucoma and 18 eyes with glaucoma. Final visual acuity of 20/100 or better was obtained in 22% of eyes with glaucoma, compared with 34% of eyes without glaucoma, and final visual acuity of finger counting and less was found in 56% and 22%, respectively (p = 0.02). The rate of ischemic occlusion was higher in the glaucoma group, 44% and 28% respectively, but the difference did not reach statistical significance. There was no difference in the rate of neovascular complications and macular edema between the two groups. The results suggest that glaucoma has an adverse effect on the visual outcome of eyes with central vein occlusion.

Prospective study of incidence and predisposing factors for clavicular fracture in the newborn.
OBJECTIVE: To determine the incidence of clavicular fracture, associated fetal and maternal risk factors and its connection with quality care control. SUBJECTS AND METHODS: A total of 3030 newborns delivered vaginally were evaluated for clavicular fractures by three separate physicians. The study group included all newborns with fractured clavicle. A control group consisted of 52 newborns delivered vaginally with no history of fractures. Maternal records were evaluated for possible predisposing factors. RESULTS: Forty-six (l.5%) newborns were found to have clavicular fractures. When compared to the control group, they were found to have a higher birthweight (3710+/-352gm vs 3235+/-405gm) an older maternal age (30.5+/-5 bs 27.7+/-6), a longer second stage of labor (34 min vs 23 min), higher rate of instrumental deliveries (13/46 vs 6/52) and shoulder dystocia (6/46 vs 1/52). Nearly 80% of newborns with clavicular fractures weighed less than 4000 gm. Multivariate analysis demonstrated two independent variables; birthweight over 3500 gm and maternal age >29. CONCLUSION: Clavicular fractures are associated with higher birthweight, older maternal age, longer second stage of labor, instrumental deliveries and shoulder dystocia. However, in most cases this injury cannot be predicted prior to delivery and thus cannot be an indicator of quality control.

A prospective study of high- versus low-dose oxytocin for induction of labor.
BACKGROUND: To assess the efficacy and safety of a high-dosage oxytocin induction regimen. METHODS: A randomized prospective study of 179 patients who received an initial dose of either 2.5 (n = 98) or 1.25 (n = 81) mU/minute of oxytocin, with increments of 2.5 mU/minute or 1.25 at 30-minute intervals. RESULTS: Failure rates (15.3% versus 19.8%), time to delivery, the number of assisted vaginal deliveries, cesarean sections, and maternal and fetal complications were not significantly different in the two protocols. However, the use of a high oxytocin dose resulted in significantly higher mean peak doses and increased total cumulative amounts. These were associated with a significant need to modify the oxytocin infusion protocol for hyperstimulation and fetal heart rate changes (65.1% versus 46.2%). CONCLUSIONS: Induction with higher dose oxytocin increments did not shorten time to delivery, but was associated with an increase in uterine hyperstimulation. Low-dose oxytocin was found to be appropriate and safe for labor induction.

Aprotinin improves hemostasis after cardiopulmonary bypass better than single-donor platelet concentrate.
Platelet transfusion and aprotinin administration improve platelet function and clinical hemostasis after extracorporeal circulation. To compare two methods of improving postoperative hemostasis, we preoperatively randomized 40 patients undergoing various open heart procedures into two groups. Group A included 20 patients who, immediately after bypass, received single-donor plateletpheresis concentrates collected from ABO-compatible donors (Baxter Autopheresis-C System). They were compared with 20 patients who received high-dose aprotinin (6 x 10(6) KIU) before and during cardiopulmonary bypass (group B). Group A patients showed significantly higher platelet count after single-donor plateletpheresis concentrate transfusion (157 +/- 36 x 10(9)/L compared with 118 +/- 42 x 10(9)/L (p < 0.05). However, platelet aggregation on extracellular matrix was better in group B (3.4 +/- 0.7 versus 2.8 +/- 0.9; p < 0.05). Total 24-hour blood loss and exposure to homologous blood products were significantly less in group B (396 +/- 125 mL and 1.1 +/- 1.6 units compared with 617 +/- 233 mL and 5.4 +/- 3.4 units; p < 0.01). Despite higher platelet count in patients after single-donor plateletpheresis concentrates transfusion, hemostasis in patients receiving aprotinin is better due to improved platelet function.

Coronary artery bypass without cardiopulmonary bypass: analysis of short-term and mid-term outcome in 220 patients.
Two hundred twenty patients, preferentially those with high-risk conditions, underwent coronary artery bypass grafting without cardiopulmonary bypass. Early unfavorable outcome events included operative mortality (7 patients, 3.2%), nonfatal perioperative myocardial infarction (6 patients, 2.7%), cerebrovascular accident (1 patient, 0.4%), and sternal infection (3 patients, 1.4%). There were two deaths (13%) among 15 patients with calcified aorta and four (12%) in 33 patients who underwent emergency operation. Multivariate analysis revealed these two risk factors to be the only predictors of early mortality (odds ratios, 8.0 and 9.8, respectively). Preoperative risk factors such as left ventricular dysfunction (ejection fraction < or = 35%) (40 patients, 18%), congestive heart failure (46 patients, 21%), acute myocardial infarction (59 patients, 27%), cardiogenic shock (7 patients, 3%), age 70 years or older (59 patients, 27%), renal failure (19 patients, 9%), and cerebrovascular accident and carotid disease (11 patients, 5%) were not found to be major predictors of early mortality or unfavorable outcome. During 12 months of follow-up (range 1 to 21 months), there were four cardiac and three noncardiac deaths (1-year actuarial survival 93%) and 17 cases (7.7%) of early return of angina. Calcified aorta, nonuse of the internal mammary artery, reoperation, and diabetes mellitus were independent predictors of unfavorable events. We conclude that coronary artery bypass grafting without cardiopulmonary bypass can be done with relatively low operative mortality, although there seems to be an increased risk for early return of angina. This procedure should therefore be considered for patients with appropriate coronary anatomy, in whom cardiopulmonary bypass poses a high risk. This procedure is still hazardous with calcified aorta or emergency operation.

Calcification of coronary arteries: detection and quantification with double-helix CT.
PURPOSE: To evaluate the accuracy of double-helix computed tomography (CT) in coronary artery calcification detection and quantification. MATERIALS AND METHODS: One hundred sixty patients with coronary disease (135 men, 25 women; age range, 45-62 years), of whom 138 had obstructive (stenosis of > 50% of diameter; n = 129) or mild (< 50% stenosis; n = 9) coronary artery disease (CAD) and 22 had normal coronary arteries (per angiographic findings), and 56 age-matched healthy control subjects underwent double-helix CT. RESULTS: Double-helix CT findings indicated that calcification was significantly more prevalent in patients with CAD (> 83%) than in patients with normal coronary arteries (27%) or in healthy control subjects (34%; P < .01). Sensitivity in detecting obstructive CAD was high (91%); however, specificity was low (52%) because of calcification in nonobstructive lesions. Comparison of double-helix CT and angiographic findings indicated that double-helix CT was 84% accurate with positive and negative predictive values of 89% and 59%, respectively. CONCLUSION: Double-helix CT is a useful noninvasive method for detection and quantification of coronary artery calcification.

A comparison between referral and hospital cervical cytology laboratory reports.
The accuracy of reports from various cytology laboratories has hitherto not been evaluated in Israel. The purpose of our study was to assess the degree of concordance between cervical cytology reports from laboratories outside our hospital with hospital cytology reports, and of both, with biopsy reports. The study group comprised 95 women referred because of an abnormal cytology smear, and who had a repeat cytology smear in the hospital within 3 months without intervening treatment. Fifty-one of these women had a colposcopically directed biopsy. We found a poor concordance between referral and hospital cervical cytology reports, and a better concordance of hospital cytology reports with biopsy findings than of referral cytology reports. There was a tendency for overdiagnosis in both the referral and the hospital cytology reports. A mechanism for continuous quality control of cervical cytology smear reports is needed.
