Background: The prevalence of extended-spectrum β-lactamase-producing organisms and their antimicrobial resistance patterns may vary between geographic areas.
Objectives: To evaluate the prevalence and susceptibility of ESBL[1]-producing organisms among Klebsiella pneumoniae and Escherichia coli isolated from adult and pediatric patients in two Israeli hospitals.
Methods: ESBL production was tested according to recommendations of the Clinical and Laboratory Standards Institute, using ceftazidime (30 μg) and a combination of ceftazidime/clavulanate (30/10 μg) disks with a ≥5 mm difference indicating positivity. Antibiotic susceptibilities were determined by the disk diffusion method according to CLSI[2] standards. Minimum inhibitory concentrations were determined by the E-test.
Results: The prevalence of ESBL-producing organisms was significantly higher among K. pneumoniae than E. coli isolates – 32% (241/765) vs. 10% (57/547) respectively (P < 0.001), and more frequently isolated from adults than children (odds ratio 2.27 for K. pneumoniae and 12.94 for E. coli). Resistance rates for amoxicillin/clavulanate, piperacillin-tazobactam, amikacin, and ciprofloxacin among the ESBL-producing K. pneumoniae and E. coli isolates were 95%, 82%, 49% and 77% for K. pneumoniae, and 77%, 35%, 25% and 100% for E. coli. Two (0.8%) ESBL-producing and 4 (0.7%) ESBL-negative K. pneumoniae isolates showed intermediate susceptibility (MIC[3] 6 μg/ml) to meropenem. All isolates were sensitive to ertapenem and colistin.
Conclusion: ESBL production among K. pneumoniae and E. coli is more prevalent in the adult population than the pediatric population and is associated with multidrug resistance.

Background: Relief of climacteric symptoms is currently the main role of hormone therapy. However, vaginal bleeding complicating this therapy is among the leading causes for its early discontinuation.
Objectives: To assess the effect of a vaginal ring delivering estradiol and progesterone in postmenopausal women and to determine whether continuous administration can relieve climacteric symptoms, produce an acceptable pattern of vaginal bleeding and control endometrial proliferation.
Methods: Twenty-nine postmenopausal women with an intact uterus were studied. All had climacteric symptoms. The vaginal rings contained 0.36 g estradiol and either 3.6 g progesterone (high dose progesterone) or 1.8 g (low dose progesterone), and were kept in place for 4–6 months. Serum progesterone, estradiol and estrone were measured and endometrial thickness determined. All women kept a daily diary of bleeding/spotting and completed a questionnaire on climacteric symptoms at monthly intervals. The low dose progesterone group comprised 14 women and the high dose progesterone group 15 women.
Results: A total of 18 patients (9 in each group) completed the study. Mean levels of estradiol, estrone and progesterone were at their peak after 2 to 4 weeks. All rings were effective in alleviating vasomotor symptoms, although there was evidence of the "escape from effect" in month 6. Endometrial thickness increased in 6 of the 29 women but biopsy in each case showed no evidence of hyperplasia. Of the 18 women who completed the study, 5 had amenorrhea throughout, 7 had amenorrhea after 3 months, and the remainder had one or two bleeding episodes after 3 months. Therapy was discontinued in 11 women.
Conclusions: A vaginal ring delivering estradiol and progesterone controlled climacteric symptoms, prevented endometrial proliferation, and provided an acceptable bleeding pattern. It should be viewed as a promising alternative for short-term estrogen-progesterone therapy.

Background: The preferred conservative treatment for congenital idiopathic clubfoot deformity remains a controversial issue.
Conclusions: Even after a relatively short follow‑up period, our success rate with the Ponseti approach already appears to be significantly higher and to bear fewer complications than the traditional treatment, in agreement with the results published by other medical centers. We now endorse the Ponseti technique of conservative manipulative treatment for congenital idiopathic clubfoot in our department.

Background: Lacking curves of “intrauterine” growth, most birthing centers in Israel use United States-based curves as standards.
Objective: To establish population-based standards of birth weight of singletons in Israel.
Methods: Data on birth weight and gestational age were obtained from the registries of the Israel Ministry of Health and Ministry of the Interior. During the 8 year study period there were 1,074,122 infants delivered in Israel; 787,710 (73%) were included in this analysis.
Results: In this study we provide data of birth weight by gestational age of live infants born in Israel between 1993 and 2001. Ranges of birth weight by gestational age are also depicted for singleton and multiple pregnancies. Fetuses in multiple pregnancies grow in a similar manner to singletons until 30 weeks of gestation, after which their growth slows down.
Conclusions: Use of these data as a standard for “intrauterine” growth better represents the Israeli neonatal population than the American standards. In addition, curves of multiple pregnancies are significantly different from those of singleton pregnancies and might be more appropriate in these pregnancies.

Background: Foreign workers in Israel are not covered by the comprehensive medical insurance that all Israelis receive. They have national insurance and injury-related coverage, which does not include routine pregnancy follow-up
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.

Background: Mastocytosis is a heterogeneous group of diseases characterized by the abnormal infiltration of mast cells in the skin and, sometimes, other organs. Some patients may experience symptoms related to mast cell mediator release.
Objective: To analyze the clinical features of cutaneous mastocytosis in a large series of children.
Methods: We conducted a file review of all children clinically diagnosed with cutaneous mastocytosis in our department over the last 20 years. We evaluated gender, age at onset, character and distribution of the lesions, associated symptoms, and course of the disease.
Results: Altogether, 180 patients with cutaneous mastocytosis were identified. The male to female ratio was 1.5:1. About one-third of patients had a mastocytoma, which was present at birth in over 40% and appeared during the first year of life in most of the remainder. Urticaria pigmentosa was noted in 65% of the patients, presenting at birth in 20% and during the first year in most of the remainder. The majority of lesions was distributed over the trunk and limbs. Different kinds of associated symptoms were noted. Prognosis, in general, was good. Only 11% of the cases, all urticaria pigmentosa, were familial.
Conclusions: Most cases of pediatric mastocytosis are sporadic and appear during the first 2 years of life, especially on the trunk. Urticaria pigmentosa is the most frequent variant. The prognosis of pediatric mastocytosis, in general, is good.

Background: Minimal invasive surgery for parathyroidectomy has been introduced in the treatment of hyperparathyroidism.
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.

Patients with silent sinus syndrome typically present for investigation of facial asymmetry. Unilateral, spontaneous enophthalmos and hypoglobus are the prominent findings at examination. Imaging of the orbit and sinuses characteristically show unilateral maxillary sinus opacification and collapse with inferior bowing of the orbital floor. It has been suggested that SSS[1] is due to hypoventilation of the maxillary sinus secondary to ostial obstruction and sinus atelectasis with chronic negative pressure within the sinus. Treatment involves functional endoscopic sinus surgery for reestablishing a functional drainage passage, and a reconstructive procedure of the floor of the orbit for repairing the hypoglobus and cosmetic deformity. Ophthalmologists, otorhinolaryngologists, and radiologists must be familiarized with this relatively newly reported disease.
