Abstract
BACKGROUND There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment. AIM To analyze the associations of birth weight, length and ponderal index with height from infancy through adulthood within mono- and dizygotic twin pairs, which provides insights into the role of genetic and environmental individual-specific factors. METHODS This study is based on the data from 28 twin cohorts in 17 countries. The pooled data included 41,852 complete twin pairs (55% monozygotic and 45% same-sex dizygotic) with information on birth weight and a total of 112,409 paired height measurements at ages ranging from 1 to 69 years. Birth length was available for 19,881 complete twin pairs, with a total of 72,692 paired height measurements. The association between birth size and later height was analyzed at both the individual and within-pair level by linear regression analyses. RESULTS Within twin pairs, regression coefficients showed that a 1-kg increase in birth weight and a 1-cm increase in birth length were associated with 1.14-4.25 cm and 0.18-0.90 cm taller height, respectively. The magnitude of the associations was generally greater within dizygotic than within monozygotic twin pairs, and this difference between zygosities was more pronounced for birth length. CONCLUSION Both genetic and individual-specific environmental factors play a role in the association between birth size and later height from infancy to adulthood, with a larger role for genetics in the association with birth length than with birth weight.

Abstract
Post-Partum Depression (PPD) occurs in 15% of pregnancies and its patho-physiology is not known. We studied female BALB/c ("depressive") and C57BL/6 (control) mice as a model for PPD and assessed their behavior and correlates with brain neurotransmitters (NTs) - norepinephrine, dopamine, serotonin and intermediates, during the pre-pregnancy (PREP), pregnancy (PREG) and post-partum (PP) periods. Depressive-like behavior was evaluated by the Open Field (OFT), Tail Suspension (TST) and Forced Swim (FST) tests. Neurotransmitters (NTs) were determined in the striatum (care-giving), hippocampus (cognitive function) and hypothalamus (maternal care & eating behavior). In the BALB/c mice, while their performance in all behavioral tests was significantly reduced during pregnancy and P-P indicative of the development of depressive-like responses, no changes were observed in the C57BL/6 mice. Changes in NTs in BALB/C were as follows: PREP, all NTs in the three brain areas were decreased, although an increase in dopamine release was observed in the hippocampus. PREG: No changes were observed in the NTs except for a decrease in 5-HT in the striatum. P-P: striatum, low 5-HT, NE and dopamine; Hippocampus: low 5-HT, NE and high Dopamine; hypothalamus: all NTs increased, especially NE. Following pregnancy and delivery, the BALB/c mice developed depressive-like behavior associated with a significant decrease in 5-HT, dopamine and NE in the striatum and 5-HT and NE in the hippocampus. Dopamine increased in the latter together with a significant increase in all NTs in the hypothalamus. These findings suggest that the development of PPD may be associated with NT changes. Normalization of these alterations may have a role in the treatment of PPD.

Abstract
OBJECTIVE Oxytocin, a hypothalamic hormone secreted upon release of ectoenzyme CD38, plays a vital role in interpersonal bonding behaviors. Reduced plasma oxytocin characterizes autistic individuals. CD38 levels, which were found to be low in LBCs derived from autistic patients, is upregulated upon the addition of a vitamin A derivative. During pregnancy, oxytocin is also secreted by placenta. Recent controversial studies have suggested an increased risk for autism when oxytocin is used during induction and augmentation of labor. We aimed to examine the tripartite relationship between oxytocin, CD38 and vitamin A in pregnant women and their newborns. METHODS Thirty-one healthy expectant mothers were enlisted for this study. Levels of oxytocin, CD38 and ATRA were measured in both maternal peripheral and newborn cord blood, and the tripartite relationship between these parameters examined. Estrogen and progesterone levels of the mothers were also recorded. Several clinical measures were also noted. RESULTS Mean maternal oxytocin and vitamin A levels were approximately 8- and 4-fold higher, respectively, than neonatal levels. CD38 expression, however, was 9 times higher in neonates than in the maternal group. Positive correlation was found between maternal and cord blood for both oxytocin and CD38. CONCLUSIONS This establishment of normative values for oxytocin, CD38 and vitamin A in healthy pregnant women and newborns may serve as a reference in the investigation of developing pathologies of disorders such as autism.

Abstract
Empathy is the ability to recognize and share in the emotions of others. It can be considered a multifaceted concept with cognitive and emotional aspects. Little is known regarding the underlying neurochemistry of empathy and in the current study we used a neurogenetic approach to explore possible brain neurotransmitter pathways contributing to cognitive and emotional empathy. Both the oxytocin receptor (OXTR) and the arginine vasopressin receptor 1a (AVPR1a) genes contribute to social cognition in both animals and humans and hence are prominent candidates for contributing to empathy. The following research examined the associations between polymorphisms in these two genes and individual differences in emotional and cognitive empathy in a sample of 367 young adults. Intriguingly, we found that emotional empathy was associated solely with OXTR, whereas cognitive empathy was associated solely with AVPR1a. Moreover, no interaction was observed between the two genes and measures of empathy. The current findings contribute to our understanding of the distinct neurogenetic pathways involved in cognitive and emotional empathy and underscore the pervasive role of both oxytocin and vasopressin in modulating human emotions.

Abstract
BACKGROUND Mast cells (MCs) and eosinophils (Eos), the key effector cells in allergy, are abundantly co-localized particularly in the late and chronic stages of allergic inflammation. Recent evidence has outlined a specialized 'allergic effector unit' in which MCs and Eos communicate via both soluble mediators and physical contact. However, the functional impact of this bi-directional crosstalk on the cells' effector activities has not yet been revealed. We aimed to investigate whether MC/eosinophil interactions can influence the immediate and late activation phenotypes of these cells. METHODS Human and murine MCs and Eos were co-cultured under various conditions for 1-2 h or 1-3 days, and in selected experiments cell-cell contact was blocked. Cell migration and mediator release were examined, and flow cytometry was applied to stain intracellular signaling molecules and surface receptors. RESULTS Eosinophils enhanced basal MCs mediator release and co-stimulated IgE-activated MCs through physical contact involving CD48-2B4 interactions. Reciprocally, resting and IgE-stimulated MCs led to eosinophil migration and activation through a paracrine-dependent mechanism. Increased phosphorylation of activation-associated signaling molecules, and enhanced release of tumor necrosis factor α, was observed in long-term co-cultures. Eosinophils also showed enhanced expression of intercellular adhesion molecule 1, which depended on direct contact with MCs. CONCLUSIONS Our findings reveal a new role for MC/eosinophil interplay in augmenting short- and long-term activation in both cells, in a combined physical/paracrine manner. This enhanced functional activity may thus critically contribute to the perpetuation of the inflammatory response in allergic conditions.

Abstract
BACKGROUND Mast cells (MCs) and eosinophils (Eos) are the key effector cells of the allergic reaction. Although classically associated with different stages of the response, the cells co-exist in the inflamed tissue in the late and chronic phases in high numbers and are likely to cross-talk. While some mediators of MCs are known to affect Eos biology and vice versa, paracrine and physical interplay between the two cells has not been described yet. We aimed to investigate whether intercellular MC-Eos communication could take place in the allergic response and exert functional bidirectional changes on the cells. METHODS Tissue sections from various allergic disorders were specifically stained for both cells. Human cord blood-derived MCs and peripheral blood Eos, co-cultured under different conditions, were studied by advanced microscopy and flow cytometry. RESULTS Several co-localized MC-Eos pairs were detected in human nasal polyps and asthmatic bronchi, as well in mouse atopic dermatitis. In vitro, MCs and Eos formed stable conjugates at high rates, with clear membrane contact. In the presence of MCs, Eos were significantly more viable under several co-culture conditions and at both IgE-activated and steroid-inhibited settings. MC regulation of Eos survival required communication through soluble mediators but was even more dependent on physical cell-cell contact. CONCLUSIONS Our findings provide the first evidence for a complex network of paracrine and membrane interactions between MCs and Eos. The prosurvival phenotype induced by this MC-Eos interplay may be critical for sustaining chronic allergic inflammation.

Abstract
BACKGROUND Mast cells activation through FcepsilonRI cross-linking has a pivotal role in the initiation of allergic reactions. The influence of this activation on programmed cell death of human mast cells has not yet been clarified. This study evaluates the influence of IgE-dependent activation alone and in synergy with TRAIL on the expression of molecules involved in the apoptotic signal transduction. METHODS Human cord blood derived mast cells (CBMC) were cultured with myeloma IgE followed by activation with anti-human IgE. The expression of proteins involved in apoptotic signal transduction was assessed by immunoblot analysis. To test the effect of activation on a pro-apoptotic stimulus, activated, IgE-treated and resting CBMC were incubated with TRAIL, or in a medium with suboptimal concentrations of stem cell factor (SCF). RESULTS In accordance with a previous study of ours, it was found that IgE-dependent activation increased TRAIL-induced caspase-8 and caspase-3 cleavage. However, it did not have a significant influence on CBMC death induced by SCF withdrawal. IgE-dependent activation increased the expression of FLIP and myeloid cell leukemia 1 (MCL-1) anti-apoptotic molecules as well as the pro-apoptotic one, BIM. In addition, a decrease in BID expression was observed. TRAIL could reverse the increase in FLIP but did not influence the upregulation of MCL-1 and of BIM. CONCLUSIONS These findings suggest that IgE-dependent activation of human mast cells induces an increase in both pro-survival and pro-apoptotic molecules. We therefore hypothesized that IgE-dependent activation may regulate human mast cell apoptosis by fine-tuning anti-apoptotic and pro-apoptotic factors.

Abstract
To analyse the use of a free, public, perinatal internet consultation service, 2000 consultations provided by university hospital staff were evaluated over 30 months. Ninety five percent of the questioners were women, and 62% of them were primiparous. The average response rate was 2.3 audience responses per question. Fifty-two percent of the consultations were related to labour and delivery, 23% were related to pregnancy complications, 16% were related to prenatal diagnosis, and 7% were related to the puerperium period. We conclude that medical consultation forums provide an additional way of delivering inexpensive, accessible, fast, and convenient healthcare services.

Abstract
BACKGROUND This prospective, non-randomized study compared post-void residual volume in laboring and postpartum women with or without epidural analgesia. METHODS The study was conducted over 1 year with institutional review board approval. Parturients were recruited in early labor and self-selected to either the study (with epidural) or control (without epidural) group. Post-void residual volume was compared between groups, using transabdominal ultrasound during labor, and on postpartum day 1 and 2. Main outcome measure was intrapartum residual bladder volume. RESULTS Thirty patients were recruited to each group. During labor, residual bladder volume was significantly larger in the epidural group compared with the non-epidural group [median (range)] 240 (12-640), ml vs. 45 (13-250) ml, respectively, P < 0.001], but was similar on postpartum day 1 and 2. Twenty-five (83%) women with epidural analgesia required bladder catheterization during labor vs. one (3.3%) without (P < 0.0001). CONCLUSION The greater post-void residual volume and increased inability to void in parturients with epidurals suggests that epidural analgesia plays a role in intrapartum urinary retention.

Abstract
Placenta accreta may be suspected prior to surgery, but the actual diagnosis is only confirmed at surgery. This prospective and observational study was performed to assess whether preparations should be made for potential massive blood loss prior to Caesarean surgery in all patients with suspected placenta accreta. Patients were classified as high or low suspicion for placenta accreta based on ultrasonography and clinical factors. Among 28 suspected cases of placenta accreta, diagnosis was confirmed at surgery in 50% (12/17 high and 2/11 low suspicion) cases. Hysterectomy was only performed in the 12 high suspicion patients with placenta accreta (p < 0.001). High suspicion patients required more blood transfusions: mean(SD) 6.5 (7.0) units vs 1.09 (1.1) units, p = 0.017. Anaesthetists should be prepared for major haemorrhage in all cases of suspected placenta accreta, although use of a system to grade level of suspicion may identify those at greater risk.

Abstract
The kinetics of reduction of the radical R*, 5-dimethylaminonaphthalene-1-sulfonyl-4-amino-2,2,6,6-tetramethyl-1-piperidine-oxyl by blood and its components were studied using the EPR technique. The results demonstrate that R* is adsorbed to the outer surface of the membrane and does not penetrate into the erythrocytes. A series of control experiments in PBS demonstrate that ascorbate is the only natural reducing agent that reacts with R*. The observed first order rate of disappearance of the nitroxide radical k, is: k(blood) > k(eryth) > k(plasma) and k(blood) approximately = k(eryth) + k(plasma). The results demonstrate that: a. The erythrocytes catalyze the reduction of R* by ascorbate. b. The rate of reduction of the radical is high though it does not penetrate the cells. c. In human erythrocytes there is an efficient electron transfer route through the cell membrane. d. The study points out that R* is a suitable spin label for measuring the reduction kinetics and antioxidant capacity in blood as expressed by reduction by ascorbate.

Abstract
An earthquake striking a highly populated area is likely to cause a mass casualty situation for even the most advanced trauma center. If the local medical teams are injured and the hospitals are damaged beyond immediate repair, external intervention is needed. In the Turkish earthquake crisis, Israel was one of many states to deploy a field hospital to the crisis site. This was set up in Adapazari, the second most severely hit city in terms of the amount of damage. The hospital provided advanced surgical and medical facilities, including laparotomy, cesarean section, and intensive care surveillance. These facilities require sophisticated laboratory and radiology services, including hematology, chemistry, microbiology, and blood bank. The speed with which the hospital must be assembled and transported to be efficient and the basic conditions of a field hospital dictate specific considerations regarding diagnostic auxiliary equipment. Considerations in choosing this equipment, problems encountered during installation, and recommendations for the future are presented.

Abstract
On August 17, 1999, an earthquake of 7.4 magnitude struck Turkey, resulting in the destruction of the cities Golcuk, Izmit, Adapazari, and Yalova. Three days later, the Israel Defense Force Field Hospital arrived at Adapazari, serving as a reinforcement hospital until the rehabilitation of the local medical facilities. Surgical services in the field hospital were supplied by general, orthopedic, and plastic surgeons. The authors evaluated all soft-tissue injuries managed at the hospital and assessed the need for plastic surgery services in a crisis intervention field hospital. Information was gathered regarding soft-tissue injuries throughout the activity of the hospital. In addition, patients' charts, operations' reports, and entry and evacuation logs were reviewed for all patients accepted and treated in the field hospital. Interviews of patients, local physicians, and citizens of Adapazari were performed to evaluate the medical situation in the first 3 days after the earthquake. A total of 1205 patients were treated by the field hospital in Adapazari; 138 (11.45 percent) of these patients sought aid for isolated soft-tissue injuries, 105 of which (76.09 percent) were earthquake-related. Twenty (51.28 percent) of the operations performed in the hospital were to treat soft-tissue injuries; 1.49 percent of all patients underwent minor surgical manipulations by the plastic surgeon on staff. Plastic surgery patients occupied 13.6 percent of the hospital beds. In conclusion, the authors find it beneficial to supply plastic surgery services at a field hospital in an earthquake situation.

Abstract
Erythrocyte aggregation was determined by a novel method enabling the quantification of the aggregation process in whole blood. Blood samples of 47 healthy pregnant women and 39 preeclamptic patients were examined. Subjects within each group were matched for the gestational age. It was found that RBC aggregation increases with the gestational age in healthy pregnancy and further increases in preeclampsia. Addition of low-molecular weight dextran (MW = 9300) to blood samples of both healthy pregnant women and preeclamptic patients reduces RBC aggregation in a concentration-dependent manner. The obtained results indicate alterations in plasma composition as the primary factor for the increased RBC aggregation in both normal and pathological pregnancy. It is suggested that adsorption of low-molecular weight dextran on the RBC membrane reduces the surface concentration of plasma bridging molecules thereby reducing RBC aggregation toward normal.

Abstract
On 17 August 1999 at 3:04 a.m., an earthquake of 7.4 magnitude (Richter scale) struck the Marmara region in Turkey. The city of Adapazari suffered 2,680 fatalities with approximately 5,300 injured. The Israeli Defence Forces (IDF) field hospital arrived at Adapazari, on day four after the quake. The team consisted of 102 personnel. The field hospital acted as a secondary referral centre. A total of 1,205 patients were treated in the field hospital between day four and day 14 of the earthquake. The frequency distribution of the medical problems seen in the field hospital was 32 per cent internal medicine, 13 per cent general surgery including plastic, 21 per cent orthopaedic surgery, 23 per cent paediatric disease, 10 per cent obstetrics and gynaecology and 1 per cent major psychiatric disorders. A mean number of 35 patients per day were hospitalised in the field hospital for between 24 hours to one week. The rapid establishment of the field hospital enabled the local medical facilities to 'buy time' in order to organise and restore surgical and hospitalisation abilities in this disastrous situation.

Abstract
The objective of this project was to establish a measurable process of continuous quality improvement of health care services in the Israeli naval primary care clinics. All navy clinics were surveyed at 6-month intervals. The quality of medical recording was evaluated, and instructive workshops were given on the matter. Real-time physician-patient interactions were evaluated, and immediate feedback was given to the examining physician. Complementary medical services were evaluated and steps toward improvement were taken. A total of 1043 medical records were examined. A general improvement in medical-record documentation (from a score of 6.0 +/- 2.5 to a score of 7.4 +/- 1.9, P < .001) was demonstrated during the first 3 years of the project. No significant change was noticed in the physician-patient interaction score. Complementary medical services improved from a score of 4.9 +/- 1.5 in 1994 to a score of 7.4 +/- 0.9 3 years later (P < .02). This project achieved a significant improvement in the quality of medical recording and of complementary medical services.

Abstract
QUESTION One of my patients is currently 14 weeks pregnant. She is a teacher in grade 1, and there is an epidemic of Fifth disease in the school where she teaches. Can this disease affect her pregnancy and how should I care for her? ANSWER Erythema infectiosum (Fifth disease) is usually a benign disease for children and mothers, but might have serious consequences for a fetus due to hemolytic anemia, although the risk is very low. You should evaluate the mother's immune status. If she is already immune (IgG positive), the risks are nil. If she is not immune (although the risk of the fetus's being affected is very low), fetal surveillance by repeated ultrasonographic examination and immune status reevaluation has been recommended. If a fetus is found to be affected, intrauterine evaluation and treatment are available at tertiary care centres.

Abstract
The primary care clinics of the Israeli Defense Forces are similar to those of the civilian health system, yet some characteristics are unique: Soldiers are a young, healthy population; their physicians are either serving in the reserves for short periods, or are primary care physicians of the regular army; and during military service the soldier is usually treated in several different primary care clinics. A detailed medical record facilitates communication between the various primary care physicians. As part of a 2-year quality assurance project all naval clinics in Israel were surveyed at 6-month intervals. From the clinic records, 685 encounters involving the 7 most common problems were randomly chosen. We evaluated the quality of the medical records of these encounters scoring them according to subjective, objective assessment and therapeutic and evaluative plan (SOAP) Each record was evaluated by 2 physicians and scored from 0 to 100, using fixed criteria. The score for the therapeutic and evaluative plan was significantly higher than that of the other parts of the medical record (80% vs. 55-59%, p < 0.001). The score of the primary care physicians was significantly higher than that of physicians of the reserves (73% vs. 63%, p < 0.001). Encounters involving upper respiratory tract infections and abdominal pain scored higher than those involving other common problems. The medical recording process has a fundamental role in medical care. Our findings suggest that the subjective, objective and assessment parts of naval medical records need improvement. Further studies might help improve the quality of primary medical care.

Abstract
The epidemic of human immunodeficiency virus (HIV) is now affecting populations that were less susceptible in the early 1980s. It is estimated that 8% of patients with AIDS in the US are women in the reproductive age, and 1% are children. In Israel up to 1992, 134 women and 14 children of infected parents were reported as carrying antibodies against the virus. A pregnant women who was a carrier prompted us to formulate various questions as to how the infection affects pregnancy and vice versa, proper management at delivery, rate and modes of perinatal transmission, risk to health care workers, and legal aspects of HIV infection in Israel.

Abstract
A 20 year old male naval crew-member suffering from sea sickness was treated with transdermal scopolamine (TS). After 5 months of continuous treatment, he developed scopolamine intoxication followed by the appearance of recurrent classic migraine attacks. He had never suffered from headache or migraine prior to TS intoxication. The migraine attacks comprised a prodrome of apathy, bad mood and loss of appetite lasting several hours. An aura of scintillating spots, left arm numbness and paresthesias lasting several minutes was followed by a severe throbbing unilateral headache with photophobia, sonophobia and nausea. After one year of repeated follow-up examination, he continued to suffer from the attacks once every 10 to 14 days, with no identified precipitating factors. We are not aware of similar cases in the medical literature. Although it is not possible to establish TS intoxication as a causal effect of the appearance of classic migraine in our patient, the temporal association and clinical course are very supportive of this assumption. Central nervous system neurotransmitter imbalance of cardiovascular alterations may possibly be implicated.

Abstract
The scheduled appointment system in primary care clinics became popular recently in Israel. Failed appointments created a problem for the doctors, patients and the clinic in Netivot. During 11 months, 2,317 appointments were surveyed. The survey showed 36% of failed appointments, with a decrease to 28% one year later. Rates of failed appointments were 38% for the paediatric population, 35% for adults, and 34% for pensioners. Market days and holidays predisposed to more failed appointments, representing community customs. The presence of a chronic disease that needed follow-up ensured a higher rate of attendance (76%), especially among the paediatric population (92% attendance rate). By contrast, a geriatric patient with an acute disease had difficulty attending the clinic (only 16% attending). 512 people (35% of the population) were responsible for the 827 failed appointments, and among them only 12% of the population accounted for 59% of the failed appointments. These findings have important implications in the planning of an appointment system in an urban health centre, and they strengthen the assumption that a small number of patients cause a large number of failed appointments.

Abstract
A cohort study investigated the specific outcomes of a health education coursed carried out by recently graduated physicians in an urban primary care setting in Israel. Questionnaires were used to study the effects of the programme on knowledge and awareness concerning antibiotic usage. The results showed a significant gain in knowledge about the causes of infectious disease, appropriate duration of antibiotic intake, side effects of antibiotics and the importance of compliance. In contrast with other studies, low income blue collar workers with less than high school education showed the most significant gains from the programme. Inexperienced physicians were able to implement a community health education programme with clearly defined goals.
