 Background: Abdominoperineal resection entails the need for a permanent colostomy, which significantly reduces patient self-image and quality of life.

Objective: To investigate the effectiveness of preoperative chemoradiation in increasing the resectability rates of rectal cancer and increasing the anal sphincter preservation rate.

Methods: The study group included 66 patients aged 33–84 years with T2–T3 rectal carcinoma who were treated in our institute from 1997 to 2002 with preoperative chemoradiation followed by surgery 6 weeks later. All patients underwent preoperative transrectal endoscopic ultrasound for tumor staging and localization. The duration of follow-up was 25 months.

Results: Chemoradiation led to tumor downstaging in 61 patients (92.4%), all of whom underwent low anterior resection. Only 11.4% of this group needed a temporary (6 weeks) loop colostomy/ileostomy. None of the 16 patients with post-treatment T0 tumors had evidence of malignant cells on pathologic study. Five patients (7.6%) failed to respond to chemoradiation and underwent APR[1]. There were no major complications, such as leakage, and no deaths.

Conclusions: Neoadjuvant chemoradiation is an effective modality to downstage advanced rectal cancer, improving patient quality of life by significantly reducing the need for a terminal permanent colostomy, or even a temporary one.

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.


Objectives: To compare the outcomes of two groups of CICF[1] patients who underwent two different treatment protocols.

Methods: The study cohort included 72 infants treated in our hospital from August 1998 to December 2002. Group 1 comprised 40 infants (61 clubfeet) who were treated by a traditional method (a modification of the Kite and Lovell technique), and group 2 consisted of 32 infants (48 clubfeet) who were treated with the Ponseti technique. Both groups were similar in age, gender and severity of the deformity (Dimeglio scoring system)

Results: After an average follow-up of 54.9 months (range 44–68), 35 (57%) clubfeet in group 1 required surgical intervention and 27 (44%) clubfeet had a residual deformity at last follow-up. In the Ponseti group, 45 (94%) clubfeet were fully corrected at last follow-up (average 29.2 months, range 16–45) while 3 (6%) clubfeet had residual deformity and required surgery. Tendo-Achilles tenotomy was performed with no complications in 47 clubfeet (in group 2) at an average age of 2.4 months (range 2–4 months).

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: 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: Approximately one‑fourth of new Crohn’s disease diagnoses are made in individuals under the age of 20 years in whom proximal Crohn’s disease tends to be more common.

Objectives: To describe the role of wireless capsule endoscopy in diagnosing isolated small intestinal Crohn’s disease in two adolescents.

Methods: Wireless capsule endoscopy was performed in two adolescents with severe protein-losing enteropathy and negative standard diagnostic workup.

Results: Wireless capsule endoscopy successfully diagnosed Crohn’s disease with uncharacteristic presentations and negative radiographic and endoscopic findings in both patients.

Conclusions: The non-invasiveness and ease in performance of capsule endoscopy on an ambulatory basis make this diagnostic modality especially advantageous for children.

Background: Although the current literature attributes most cases of hematospermia to an infectious agent, identification of the specific pathogens involved has been limited.

Objectives: To determine the prevalence of different pathogens in patients presenting to our sexually transmitted disease clinic with hematospermia.

Methods: Between January 1999 and January 2000, 16 patients presented to our STD[1] clinic with hematospermia after other non-infectious pathologies had been excluded by a referring physician. After obtaining informed consent, subjects completed a questionnaire addressing symptoms and sexual behavior. First void urine samples, as well as genitourinary and serum specimens were tested for Chlamydia trachomatis, Ureaplasma urealyticum and Herpes simplex virus. Standard bacterial cultures were also performed.

Results: Laboratory testing detected a pathogen in 12 of the 16 males presenting with hematospermia. The sexually transmitted pathogens detected were Herpes simplex virus in 5 patients (42%), Chlamydia trachomatis in 4 (33%), Enterococcus fecalis in 2 (17%), and Ureaplasma urealyticum in 1 (8%). In all cases in which a pathogen was identified, the appropriate antimicrobial agent was administered. Symptoms resolved for each patient following antimicrobial therapy. During a 1 year follow-up, all 12 patients remained free of disease.

Conclusions: Recent advances in microbiologic diagnostic techniques have facilitated the detection of pathogens in patients with hematospermia, thereby enhancing the efficacy of treatment.

Background: Women with myocardial infarction have a less favorable prognosis than men. Many studies have indicated gender bias in the evaluation and treatment of myocardial infarction, but few data exist concerning these aspects in the management of unstable angina.


Objective: To investigate gender differences in the baseline characteristics, clinical presentation, treatment and prognosis of women with unstable angina.

Method: Data were collected prospectively as part of the Acute Coronary Syndromes Israeli Survey in 2000 at Soroka University Medical Center. In-hospital management and 2 year follow-up were monitored for 226 consecutive patients with unstable angina admitted to our medical center during February and March 2000.

Results: Women were older (71 ± 12 vs. 66 ± 12, P = 0.006), more diabetic (41.3% vs. 34.5%, not significant) and hypertensive (76.3% vs. 64.6%, P = 0.07). Women presented more often with atypical chest pain (18.8% vs. 7.5%, P = 0.038). Heparin, aspirin and angiotensin-converting enzyme inhibitor were equally delivered, but more beta-blockers were administered to women (88.5% vs. 75.7%, P = 0.02) and more statins to men (48.1% vs. 35.4%, P = 0.07). Angiography rates were similar (17.7% vs. 19.6%). Similar management was documented during the 2 year follow-up. Re-hospitalization rates were similar (53.3% of women and 63.7% of men, NS). Men had a tendency to develop acute myocardial infarction more often (9.6% vs. 2.7%, P = 0.06) and to develop peripheral vascular disease (3.7% vs. 0%, P = 0.09), and they had a non-significant higher rate of coronary artery bypass graft (6.7% vs. 1.3%, P = 0.08). No gender difference was found in angiography (14.7% of women vs. 16.3% of men) or percutaneous intervention (13% vs. 16.7%). At 2 years there was no gender-related difference in mortality (13.3% of women vs. 16.3% of men, NS). Kaplan-Meier analysis for event-free survival after 2 years showed no gender difference in survival. Multi-regression analysis showed that gender was not a prognostic factor for survival.

Conclusions. We found no major difference in the management of men and women with unstable angina. Although men showed a tendency to suffer more major cardiac events, their 2 year prognosis was the same as for women.

Background: Hemodynamic changes, including systemic vascular resistance, in cirrhotic patients during massive paracentesis have been reported, but large and small artery compliance has not yet been investigated.

Objective: To investigate hemodynamic variables, including small and large artery compliance, in cirrhotic patients during total paracentesis.

Methods: The study included 15 cirrhotic patients admitted for an episode of tense diuretic-resistant ascites. Hemodynamic variables including vascular compliance were measured using an HDI pulse wave cardiovascular profiling instrument CR-2000. The variables were measured in these patients before, immediately after and 24 hours following large volume (mean 5.6 L) paracentesis.

Results: Cardiac output increased immediately after paracentesis due to increment in stroke volume, with no change in heart rate. However, 24 hours later the cardiac output decreased to below the basal level. The fluctuation was statistically significant (P < 0.05). There was no change in large artery compliance, but small artery compliance increased after paracentesis (P < 0.05) and partially returned to the basal level after 24 hours. Systemic vascular resistance measurement showed the same pattern of change: vasodilatation occurred during paracentesis and was attenuated 24 hours later.

Conclusions: Large volume paracentesis with albumin replacement caused an accentuation of the vasodilatation (small but not large artery) already present in these patients. This may be the first sign of enhanced vasodilatation due to large volume paracentesis before the clinical expression of impaired hemodynamics and deterioration of renal function.
