Objectives: To compare perinatal outcome between partially insured non-resident migrants in Israel and comprehensively insured Israeli women.

Methods: Parameters of perinatal outcome were compared between 16,012 Israeli and 721 foreign women living in Israel. Outcome measures included birth weight, distribution of gestational age at delivery, neonatal complications, cesarean section, neonatal intensive care unit admission, intrauterine fetal death rates, and duration of post-partum hospitalization.

Results: Deliveries prior to 28 weeks gestation occurred more frequently among non-residents (1.3% vs. 0.6%, P < 0.001). Gestational diabetes and preeclamptic toxemia were significantly more prevalent among non-residents (3.2% vs. 1.9%, P < 0.05 and 4.9% vs. 3.1%, P < 0.05, respectively). The cesarean rates were 18% and 35% for residents and non-residents, respectively (P < 0.001), and the post-cesarean recovery period was longer among non-residents (4.8 vs. 3.6 days, P < 0.05). The mean birth weight was similar in the two groups (3,214 vs. 3,231 g), although macrosomia (>4,000 g) was more prevalent among non-residents, who also had higher rates of NICU[1] admission ((9.6% vs. 8%, P < 0.05) and intrauterine fetal death (6.6/1,000 vs. 3.7/1,000, P < 0.05).

Conclusions: Non-resident parturients in Israel are more susceptible to an adverse perinatal outcome than their Israeli counterparts. We suggest that governmental subsidization of non-residents' health expenditures would reduce the differences in perinatal outcome between these two groups.

Objective: To evaluate the contribution of the sestamibi-SPECT (MIBI) localization, cervical ultrasonography, and intraoperative rapid turbo intact parathormone assay in minimal invasive parathyroidectomy.

Methods: Between August 1999 and March 2004, 146 consecutive hyperthyroid patients were treated using the MIBI and ultrasound for preoperative localization and iPTH[1] measurements for intraoperative assessment.

Results: Parathyroid adenoma was detected in 106 patients, primary hyperplasia in 16, secondary hyperplasia in 16, tertiary hyperplasia in 5 and parathyroid carcinoma in 1 patient. Minimal invasive exploration of the neck was performed in 84 of the 106 patients (79.2%) with an adenoma, and in 17 of them this procedure was performed under local cervical block anesthesia in awake patients. Adenoma was correctly diagnosed by MIBI scan in 74% of the patients, and by ultrasound in 61%. The addition of ultrasonography to MIBI increased the accuracy of adenoma detection to 83%. In 2 of the 146 patients (1.4%) iPTH could not be significantly reduced during the initial surgical procedure. Minimal invasive surgery with minimal morbidity, and avoiding bilateral neck exploration, was achieved in 79.2% of patients with a primary solitary adenoma.

Objectives: To define the incidence of congenital CMV infection in two different subpopulations, as a model for the entire population of Israel.

Methods: Urine specimens were randomly collected from 2,000 newborns in Shaare Zedek Medical Center, Jerusalem, and HaEmek Medical Center, Afula (1,000 specimens each). These hospitals have many characteristic differences, presumably representing the diverse population of Israel. Urine specimens were subjected to a CMV PCR[2] reaction and positive specimens were validated by urine viral culture. Maternal seroprevalence was determined in a representative sample of the mothers in each hospital. Epidemiologic characteristics of the mothers were extracted from hospital records and compared.

Results: The population in Shaare Zedek Medical Center was mostly Jewish (95.8%) and urban (87.0%), as compared to that of HaEmek Medical Center (49.2% and 61.0%, respectively, P < 0.01). Nevertheless, CMV seroprevalence was similar: 81.5% and 85%, respectively. Ten (1.0%) and 4 (0.4%) newborns, respectively, were found to have congenital CMV infection (not significant).

Conclusions: The combined incidence of congenital CMV infection in the study population was 0.7% (95% confidence interval 0.3–1.0%). If this rate is extrapolated to the entire population of Israel, then a total of 945 cases of congenital CMV can be expected among the 135,000 annual deliveries. A nationwide screening program for congenital CMV should be considered.

Background: Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical procedure of choice for patients with ulcerative colitis and familial adenomatous polyposis.

Objectives: To evaluate the long-term functional outcome of patients who underwent this surgical procedure.

Methods: We performed this observational study in 174 consecutive patients: 146 with UC[1] and 28 with FAP[2]. The patients, 91 males and 83 females with a mean age of 34.1 ± 10.6 years (range 6–67 years), underwent the procedure between January 1984 and January 2004 (mean follow-up 64.8 months, range 1–240 months). The indications for surgery were intractable disease in 124 patients (71%), dysplasia in 36 (21%), severe bleeding in 8 (5%), and perforation in 6 (3%).

Results: A protective ileostomy was performed in 140 patients (96%) with UC and 12 (43%) with FAP. An urgent three-stage procedure was necessary in 14 patients (8.4%). A mucosal proctectomy was performed in 94 (54%), and a double stapling technique in 80 (46%). Mean length of hospital stay was 9.4 ± 6.6 days (range 5–34 days, median 8). Complications included pelvic sepsis in 7 patients (4.2%), anastomotic leakage in 8 (4.8%), bowel obstruction in 22 (13.2%), incisional hernia in 12 (7.2%), anastomotic stenosis that usually responded to manual dilatation in 46 (27.6%), pouchitis in 106 (61%), recto-vaginal fistula in 3 (1.8%), retrograde ejaculation in 3 (1.8%), and impotence in 2 (1.2%). There was no mortality in this group of patients. The median number of bowel movements per 24 hours was six in UC patients and five in FAP patients, with at least one bowel movement during the night. Complete daytime and night-time continence was documented in 124 patients (71%). Overall satisfaction was 95%.

Conclusions: Restorative proctocolectomy with ileal pouch-anal anastomosis confers a long-term good quality of life to both UC and FAP patients, and the majority of patients are fully continent with five to six bowel movements per day. 

Background: The physical properties of cancerous skin tissue have rarely been measured in either fresh or frozen skin specimens. Of interest are the elastic properties associated with the skin's ability to deform, i.e., to stretch and compress. Two constants – Young’s modulus and Poisson’s ratio – represent the basic elastic behavior pattern of any elastic material, including skin. The former relates the applied stress on a specimen to its deformation via Hooke’s law, while the latter is the ratio between the axial and lateral strains.

Objectives: To investigate the elastic properties of cancerous skin tissue. For this purpose 23 consecutive cancerous tissue specimens prepared during Mohs micrographic surgery were analyzed.

Methods: From these specimens we calculated the change in radial length (defined as the radial strain) and the change in tissue thickness (defined as axial strain).

Results: Based on the above two strains we determined a Poisson ratio of 0.43 ± 0.12 and an average Young modulus of 52 KPa.

Conclusions: Defining the elastic properties of cancerous skin may become the first step in turning elasticity into a clinical tool. Correlating these constants with the histopathologic features of a cancerous tissue can contribute an additional non-invasive, in vivo and in vitro diagnostic tool.

Background: Head lice move easily from head to head. The lack of safe, effective repellents leads to reinfestation.

Objectives: To test the efficacy of a slow-release citronella formulation as a repellent against the head louse.

Methods: During 4 months in 2003 a randomized, placebo-controlled double-blind clinical study was conducted in four elementary schools; 103 children were treated with the test formulation and 95 with a placebo.

Results: A significant difference was observed during the second examination 2 months later, when 12.0% of the children treated with the test repellent and 50.5% of those treated with placebo were infested with lice. A significant difference was also observed at the third examination 2 months later, when 12.4% of the children treated with the test repellent and 33.7% treated with placebo were infested. Overall, there were significant differences between those treated with the repellent and those treated with the placebo (15.4% and 55.1% respectively, P < 0.0001). Side effects were observed in 4.4% of children who disliked the odor of the formulation, and an additional 1.0% who complained of a slight itching and burning sensation.

Conclusions: Use of an effective repellent could significantly lower the incidence of reinfestations, which would lower expenditure on lice control, including pediculicides, combs and products for nit removal, and the time spent on treatment and removal of the nits.

Background: The appearance of pericarditis following insertion of a permanent pacemaker is not widely acknowledged in the literature.

Objectives: To describe our experience with pericarditis following 395 permanent pacemaker implantations over 2 years.

Methods: We retrospectively reviewed the medical records of 395 consecutive patients in whom new pacing systems or pacemaker leads had been implanted over a 2 year period. We searched the records for pericarditis that developed within 1 month after pacemaker implantation according to the ICD-9 code. The incidence, clinical picture, response to treatment and relationship to lead design and location were studied.

Results: Eight cases (2%) of pericarditis following implantation were detected. Clinical manifestations in all patients were similar to those of post-pericardiotomy syndrome and included chest pain (n=7), friction rub (n=1), fever (n=2), fatigue (n=2), pleural effusion (n=2), new atrial fibrillation (n=2), elevated erythrocyte sedimentation rate (n=4) and echcardiographic evidence of pericardial effusion (n=8). All affected patients had undergone active fixation (screw-in) lead implantation in the atrial position. The incidence of pericarditis with screw-in atrial leads was 3% compared to 0% in other cases (P < 0.05).

Conclusions: Pericarditis is not uncommon following pacemaker implantation with active fixation atrial leads. Special attention should be paid to identifying pericardial complications following pacemaker implantation, especially when anticoagulant therapy is resumed or initiated. The use of passive fixation leads is likely to reduce the incidence of pericarditis but this issue should be further investigated.

Background: Oral contraceptive users are at increased risk for both arterial and venous thrombosis, some of which can be fatal. Studies are consistent with the existence of a synergism between cigarette smoking and OC[1] use in the pathogenesis of myocardial infarction in young women.

Objectives: To study the relationship between OC use, cigarette smoking and other cardiovascular risk factors among young women.

Methods: A systematic sample of military personnel, upon discharge from service in the Israel Defense Forces, was asked to complete a research questionnaire. Body weight and height were measured and body mass index computed.

Results: Overall, 16,258 questionnaires were collected and analyzed during this 20 year study. There was a gradual, significant increase in OC use until the mid-1980s, from approximately 45% to 60% (P < 0.001), followed by steady rates of 58–64% since then. In contrast, the rates of smoking decreased significantly in the mid-1980s, from approximately 42% to a nadir of 22% in 1991. Since then, the rate of smoking has increased slowly but steadily, to reach a level of 35% in 1999. The OC users were more often of western (Ashkenazi) origin and came from families with more education and fewer siblings. They were more often smokers than non-OC users, and started smoking at a younger age. They had significantly lower BMI[2] than non-users. OC use was nearly identical in groups with or without multiple cardiovascular risk factors (smoking, obesity, family history).

Conclusions: Smoking and OC use are strongly associated. Other cardiovascular risk factors (smoking, obesity, family history) do not prevent OC users from smoking or smokers to use OC. We suggest that primary care physicians discourage smoking among adolescent females who wish to start using OC. A thorough medical history should be obtained to recognize all risk factors for cardiovascular disease and to provide for appropriate contraception counseling.

Histiocytosis of childhood is characterized by localized or generalized proliferation of cells of the mononuclear phagocyte system and the dendritic cell system. In patients with Langerhans cell histiocytosis, the orbita is the most involved site encountered in ophthalmic practice, usually as a lytic lesion in the zygomaticofrontal suture. Patients usually present with acute or chronic periorbital swelling. Electron microscopic findings of Birbeck granules and positive staining for CD1 antigenic determinant confirm the diagnosis.

The management of uncontrolled bleeding in trauma patients is difficult in the prehospital setting, especially when transfer time to a care facility is prolonged. The goal of treatment is to stabilize the patient until surgery can be performed. In modern practice, the major aspects of optimal patient stabilization are the timing and volume of resuscitation and the use of blood products. The main problems are the logistics of handling the blood products as well as achieving the appropriate endpoint or resuscitation, while balancing the need to maintain blood pressure with the need to avoid deleterious coagulopathy. This work reviews current therapeutic modalities for prehospital management of uncontrolled bleeding trauma patients, namely low volume resuscitation, packed red blood cells, hemoglobin solutions, perfluorocarbons, hypertonic saline solutions, and recombinant activated factor VII.

Background: The external approach is the golden standard for sinonasal tumor removal but it is associated with several side effects, including facial scars, intracranial and extracranial complications, a long hospitalization period and high costs. Endoscopic sinus surgery enables resection of benign and selected malignant sinonasal tumors and has the advantages of no facial scars, better functional and structural preservation of the sinonasal complex, minimal trauma to surrounding tissue, a shorter hospitalization stay and lower costs.

Objectives: To evaluate the advantages and limitations of endoscopic resection of benign and malignant sinonasal tumors, their recurrence and complication rates.

Methods: The medical and radiology records of 56 patients who underwent endonasal endoscopic resection of benign and malignant sinonasal tumors between 1996 and 2003 were retrospectively reviewed. Tumors located in the center of the nose and sinuses were endoscopically resected.

Results: Six cases of malignant tumor and 50 cases of benign tumor underwent resection by ESS[1]. One of the patients with malignant tumor died, the remainder showing no evidence of disease on follow-up of 3–60 months (mean 26.8 months). Inverted papilloma was the most common benign tumor (40 patients). Seven patients (18%) had recurrence followed by endonasal resection. No major complications were recorded. Hospitalization stay was 2–7 days (mean 3.6 days).

Conclusions: Endoscopic resection of benign sinonasal tumors that are centrally located in the nose and sinuses should be considered before the external approach is used. In very carefully selected cases of malignant tumors ESS is oncologically acceptable, but more experience is needed for discerning the indications for endoscopic resection of malignant tumors. The complication rate for endoscopic resection is low, there are no facial scars, hospitalization stay is short, and costs are low.
