Objectives: To assess patient satisfaction, subjective long-term continence and complications after AMS 800 artificial urinary sphincter implantation.

Methods: The medical records of 34 patients who underwent artificial urinary sphincter implantation for radical prostatectomy (n=23), simple prostatectomy (n=9) or neurogenic disease (n=2) between 1995 and 2003 were studied retrospectively. Median follow-up was 49 months (range 3–102 months). Records were analyzed for urinary sphincter survival and complications. Quality of life and continence assessment was done by mailing an impact questionnaire.

Results: In 4 of the 34 patients (11.7%) the device was removed due to infection. One of the four had surgical revision elsewhere, and the other three were not interested in re-implantation of the device. Two patients (5.9%) underwent revisions due to mechanical failure. One patient died and three patients were not located. Twenty-seven out of a possible 30 patients (88%) completed the questionnaire; 22 (85%) achieved social continence (0–2 pads daily), and one patient had subjective difficulty activating the device. Subjective improvement and patient satisfaction was rated as 4.22 and 4.11, respectively (scale 0 to 5).
Conclusions: Artificial urinary sphincter implantation is an efficacious option for sphincter-related incontinence. This study documents the positive impact of artificial urinary sphincter implantation on quality of life with acceptable complications; these results are comparable to other published studies.

Background: Follow-up examinations in a rehabilitation center clinic after stroke are essential for coordinating post-acute services and monitoring patient progress. Of first-stroke patients discharged from our rehabilitation ward to the community 92% are invited for ambulatory check-up once every 6 months.

Objectives: To review patient complaints at follow-up and the recommendations issued by the attending physical medicine and rehabilitation specialist at the outpatient clinic.

Methods: We extracted relevant data from the records, and assessed the relationship between functional status on admission and discharge (measured by FIM[1]), length of stay, and number of complaints. Patients were divided according to the side of neurologic damage, etiology, whether the stroke was a first or recurrent event, and main clinical syndrome (neglect or aphasia).

Results: Patients' complaints included: decreased hand function (40%), general functional deterioration (20%), difficulty walking (11%), speech dysfunction (10%), various pains (especially in plegic shoulder) (8%), urine control (2%), sexual dysfunction (3%), swallowing difficulties (2%), and cognitive disturbances (2%). Patients received the following recommendations: physiotherapy (52.5%), occupational therapy (37.5%), speech therapy (12.5%), different bracing techniques (22.5%), pain clinic treatment (12.5%), changing medication prescriptions (7.5%), psychological treatment (10%), sexual rehabilitation (5%), vocational counseling (2.5%), counseling by social workers (2.5%), and recurrent neuropsychological diagnosis (2.5%). A reverse correlation was found between the number of complaints and FIM at admission (P = 0.0001) and discharge (P = 0.0003), and between LOS[2] and FIM at admission (P = 0.0001) and discharge (P = 0.004). A direct correlation was found between the number of complaints and LOS (P = 0.029). No relation was found between age, type of stroke, first and recurrent event, and clinical syndromes and patient complaints in the outpatient rehabilitation. Community rehabilitation services met 58% of all recommendations in 62% of patients, mainly physiotherapy and occupational therapy, with 34% of patients waiting for implementation of the recommendations and 4% not available for follow-up.

Conclusions: Follow-up examinations should be an integral part of post-stroke rehabilitation. Rehabilitation treatment in the community must be strengthened.

Israel has a National Screening Program for early detection of breast cancer. The need to continue and even expand this program was recently stressed in light of the high risk in the population. However, the optimal modalities for breast cancer screening are controversial, especially for women at risk. Mammography, the established screening method, is critically examined, and molecular imaging techniques, such as magnetic resonance spectroscopy and spectroscopic imaging are explored, especially for primary breast cancer detection. MRS[1] and MRSI[2] are currently limited by their reliance on the conventional framework for data analysis in biomedical imaging, i.e., the fast Fourier transform. Recent mathematical advances in signal processing via the fast Pade transform can extract diagnostically important information, which until now has been unavailable with in vivo MRS. A clinical MRS signal illustrates the rapid and stable convergence provided by FPT[3], yielding accurate information about key metabolites and their concentrations at short acquisition times. We suggest that the next step would be to apply the FPT to in vivo MRS/MRSI signals from patients with breast cancer and to compare these to findings for normal breast tissue. The potential implications of such an optimized MRS/MRSI for breast cancer screening strategies are discussed, especially for younger women at high risk.

Background: Laron Syndrome, first described in Israel, is a form of dwarfism similar to isolated growth hormone deficiency caused by molecular defects in the GH[1] receptor gene.

Objective: To characterize the molecular defects of the GH-R[2] in Laron syndrome patients followed in our clinic.

Methods: Of the 63 patients in the cohort, we investigated 31 patients and 32 relatives belonging to several ethnic origins. Molecular analysis of the GH-R gene was performed using the single strand conformation polymorphism and DNA sequencing techniques.

Results: Eleven molecular defects including a novel mutation were found. Twenty-two patients carried mutations in the extracellular domain, one in the transmembrane domain, and 3 siblings with typical Laron syndrome presented a normal GH-R. Of interest are, on one hand, different mutations within the same ethnic groups: W-15X and 5, 6 exon deletion in Jewish-Iraqis, and E180 splice and 5, 6 exon deletion in Jewish-Moroccans; and on the other hand, identical findings in patients from distinct regions: the 785-1 G to T mutation in an Israeli-Druze and a Peruvian patient. A polymorphism in exon 6, Gly168Gly, was found in 15 probands. One typical Laron patient from Greece was heterozygous for R43X in exon 4 and heterozygous for Gly168Gly. In addition, a novel mutation in exon 5: substitution of T to G replacing tyrosine 86 for aspartic acid (Y86D) is described.

Conclusions: This study demonstrates: a) an increased focal incidence of Laron syndrome in different ethnic groups from our area with a high incidence of consanguinity; and b) a relationship between molecular defects of the GH-R, ethnic group and geographic area.

Background: Transmission of Pseudomonas aeruginosa among cystic fibrosis patients attending health camps has been reported previously.

Objectives: To determine the transmission of P. aeruginosa among CF[1] patients during three winter camps in the Dead Sea region in southern Israel.

Methods: Three consecutive CF patient groups were studied, each of which spent 3 weeks at the camp. The patients were segragated prior to camp attendance: patients who were not colonized with P. aeruginosa constituted the first group and colonized patients made up the two additional groups. Sputum cultures were obtained upon arrival, at mid-camp and on the last day. Environmental cultures were also obtained. Patients were separated during social activities and were requested to avoid social mingling. Isolates were analyzed by antibiotics susceptibility profile and by pulsed field gel electrophoresis.

Results: Ninety isolates from 19 patients produced 28 different fingerprint patterns by PFGE[2]. Isolates from two siblings and two patients from the same clinic displayed the same fingerprint pattern. These patients were already colonized with these organisms upon arrival. Two couples were formed during the camp, but PFGE showed no transmission of organisms. All other patients' isolates displayed unique fingerprint patterns and were distinguishable from those of other attendees, and none of the P. aeruginosa-negative patients acquired P. aeruginosa during camp attendance. Environmental cultures were negative for P. aeruginosa.

Conclusions: We were unable to demonstrate cross-infection of P. aeruginosa among CF patients participating in health camps at the Dead Sea who were meticulously segregated.

Background: Prenatal care in Israel is established as a universal service, but the degree of compliance with care recommendations may vary with the healthcare provider or the characteristics of the population.

Objectives: To study referral to and compliance with the performance of ultrasound, alpha-fetoprotein and amniocentesis and the factors associated with them in a national sample. 

Methods: The sampling frame consisted of women who gave birth during March 2000. The sample included 1,100 Israeli Jewish and Arab women who resided in localities with over 50,000 and 20,000 inhabitants respectively. They were interviewed by phone 3 months after delivery. 

Results: In both population groups 30% reported having seven or more ultrasounds during pregnancy. The performance of fetal body scans was relatively low. Factors associated with non-performance among Jewish women were: lower education, religiousness, and attending Mother and Child Health services as compared to all other services. Seventy-seven percent of Jewish women and 84% of Arab women reported that they had been referred for alpha-protein tests. For women aged 35 and over, 55% of Jewish women were referred and 63% complied, whereas 39% of Arab women were referred but none complied.

Conclusions: Ultrasound is almost universally performed among Jewish and Arab women; however fetal body scans, alpha-fetoprotein and amniocentesis (for women over the age of 35) are not. The reasons for the lower coverage may be due to under-referral and/or lack of compliance of the women, perhaps due to sociocultural barriers. In both population groups considerable out-of-pocket money is paid for the tests.

Background: Prone sleeping has been recognized as a risk factor for sudden infant death syndrome. Ten years ago, non-prone sleeping was recommended in many countries around the world including Israel. The rate of infants sleeping prone and the rate of parents' adherence with the recommendations have not been studied.

Objectives: To study infants' sleep position and parents’ adherence to recommendations, and to identify risk factors for prone sleeping following the campaign to prevent prone sleeping in the Israeli population.

Methods: We conducted a longitudinal telephone survey with the parents of 608 randomly selected 2 month old infants, repeated at 4 and 6 months.

Results: Non-prone sleeping decreased from 75% to 67% and 63% at 2, 4 and 6 months respectively. There was a significant relationship between prone positioning and the use of a home apnea monitor at 2 months (P = 0.038, odds ratio 1.37, 95% confidence interval 0.94–2.15). Other risk factors for prone sleeping were the level of religious practice, with ultra-Orthodox Jews having the highest prevalence (2 months: OR[1] 2.78, 95% CI[2] 1.75–4.55) and higher parity – especially in families with more than five children (P = 0.041).

Conclusions: The prone sleeping position is relatively high in Israel. Groups at high risk were closely associated with the level of religiousness and parity. Efforts to promote supine sleeping should be directed towards identifiable groups.

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.
