Background: In compliance with public health measures initiated by the Israel Ministry of Health following an outbreak of influenza, amantadine was administered to all patients in the psychogeriatric department of Lev Hasharon Mental Health Center to reduce transmission and illness severity in this susceptible population.

Objectives: To evaluate the potential beneficial effects of amantadine on elderly hospitalized patients with persistent schizophrenia.

Methods: We conducted a retrospective case review of the treatment effects of amantadine on the mental, cognitive and clinical states of elderly chronic schizophrenic patients who received concomitant amantadine treatment and were routinely evaluated with the Positive and Negative Syndrome Scale, the Mini Mental State Examination, and Sandoz Clinical Assessment Geriatric Scale.

Results: No significant differences before and after amantadine treatment were noted. Conclusion: Amantadine did not influence the mental, cognitive and clinical states of elderly schizophrenia patients and thus can be considered as an anti-influenza preventive measure for this population, when indicated.

Background: Enteral nutrition in the critically ill patient is often complicated by gastrointestinal intolerance, manifested by a large gastric residual volume. The frequency of GRV[1] assessment and the intolerant level above which feeding is stopped is controversial.

Objectives: To evaluate a novel approach to EN[2] by allowing high GRV and once-daily assessment that was correlated with the paracetamol absorption test.

Methods: We conducted a pilot prospective study in an 18 bed general intensive care unit. The study group comprised 52 consecutive critically ill mechanically ventilated patients. Enteral nutrition was started at full delivery rate. Once-daily assessment of GRV with three consecutively repeated threshold volumes of 500 ml was performed before stopping EN. The paracetamol absorption test was performed and correlated to GRV. Patients were divided into two groups: low GRV (< 500 ml), and high GRV (at least one measurement of GRV > 500 ml). Clinical outcome included maximal calories delivered, incidence of pneumonia, ICU[3] length of stay, and ICU and hospital mortality.

Results: There were 4 patients (9.5%) with ventilator-associated pneumonia in the low GRV group and 3 (30%) in the high GRV group (P = 0.12). GRV was inversely correlated to paracetamol absorption; however, neither GRV nor paracetamol absorption was associated with the development of pneumonia. Both groups had similar ICU length of stay (11.0 ± 8.2 vs. 13.8 ± 14.4 days, P = 0.41), and similar ICU (21% vs. 40%, P = 0.24) and hospital mortality (35% vs. 40%, P = 1.0).

Conclusions: In critically ill mechanically ventilated patients, allowing larger gastric residual volumes, measured once daily, enables enteral feeding with fewer interruptions which results in high calorie intake without significant complications or side effects.

Background: The existence of "ophthalmoltonic consensual reaction," a contralateral change in intraocular pressure in the fellow eye induced by treatment of the first eye only, was suggested in 1924. Since then, the validity of this mechanism has been controversial.

Objectives: To assess intraocular pressure changes in the contralateral fellow eyes of patients treated with IOP[1]-lowering medication in one eye, and investigate the existence of an ophthalmotonic consensual reaction.

Methods: The study population included 38 patients with newly diagnosed bilateral ocular hypertension or early open angle glaucoma. One eye of each patient was randomly treated with one of five compounds: prostaglandin analogues, beta-blockers, alpha-2 agonists, carbonic anhidrase inhibitors and a combination therapy: dorzolamide hydrochloride–timolol maleate (Cosopt®, Sharpe & Dohme). The eye with the higher baseline IOP was selected to be the treated eye. After 3 weeks a masked examiner measured the IOP in both the treated and untreated eye.

Results: Mean IOP of the treated eyes at baseline was 26.1 ± 4.2 mmHg and at follow-up 20.2 ±2.9 mmHg, a reduction of IOP from baseline of -6 ± 3.8 mmHg, a mean percent reduction of -22 ± 10.1%. In the contralateral eyes, the mean IOP at baseline was 24.2 ± 3 mmHg and 23.1 ± 3.1 mmHg at follow-up; IOP reduction from baseline was -1.2 ± 1.8 mmHg, or mean percent reduction -4.7 ± 7.1%. A major contralateral IOP decrease was seen only in the beta-blockers and the combination (Cosopt®) treatment groups (-6.1 ± 8.3% and -12.3 ± 8.3% mean percent reduction, respectively, P < 0.05). The contralateral eyes in the prostaglandin analogues, CAI[2] or α2-agonist groups showed only a small change in IOP (-2.6 ± 4.6%, -3.2 ± 2.6%, +0.7 ± 3.3%, mean percent reduction, respectively, P < 0.05).

Conclusions: The existence of an ophthalmoltonic consensual reaction was not supported.

Background: Simulation-based medical education has become a powerful tool in improving the quality of care provided by health professionals.

Objectives: To evaluate the effect of a simulated patient-based educational program for military recruitment center physicians on the quality of medical encounters with adolescent candidates for military service.

Methods: Twelve physicians participated in an educational intervention that included a one day SP[1]-based workshop, where simulations of eight typical candidates for military service were conducted. Assessment of the physicians' performance before and after the intervention was based on questionnaires filled by 697 and 508 military candidates respectively, upon completion of their medical examination by these physicians. The questionnaire explored health topics raised by the examining physician as well as the atmosphere during the encounter. The candidates were also asked whether they had omitted important medical information during the medical encounter.

Results: Pre- and post-intervention comparison revealed significant changes in the percentages of candidates who reported that they were asked questions related to psychosocial topics: school problems – 59.7% and 68.9% (P = 0.01), protected sex – 29.6% and 36.4% (P = 0.01), mood changes – 46.9% and 52.2% (P = 0.05) respectively. Physicians were perceived as being interested in the candidates by 68.2% of the candidates before the intervention and 77.5% after (P < 0.01). The percentage of candidates who reported omitting medical information decreased from 6.6% before the intervention to 2.4% after (P < 0.01).

Conclusions: A simulated patient-based educational program for military physicians improved the quality of physician-candidate encounters. Such programs may serve as an effective instrument for training physicians to communicate with adolescents.

Background: The prevalence of aortic stenosis increases with advancing age. Once symptoms occur the prognosis in patients with severe aortic stenosis is poor. The current and recommended treatment of choice for these patients is surgical aortic valve replacement. However, many patients, mainly the very elderly and those with major comorbidities, are considered to be at high surgical risk and are therefore denied treatment. Recently, a transcatheter alternative to surgical AVR[1] has emerged.

Objectives: To describe the first year experience and 30 day outcome of transcatheter aortic self-expandable CoreValve implantation in Israel.

Methods: Transcatheter aortic valve implantation using the CoreValve system has been performed in Israel since September 2008. In the following year 55 patients underwent CoreValve TAVI[2] in four Israeli centers.

Results: Patients' mean age was 81.7 ± 7.1 years; there were 35 females and 20 males. The mean valve area by echocardiogram was 0.63 ± 0.16 cm². The calculated mean logistic Euroscore was 19.3 ± 8%. Following TAVI, mean transvalvular gradient decreased from baseline levels of 51 ± 13 to 9 ± 3 mmHg. The rate of procedural success was 98%. One patient died on the first day post-procedure (1.8%) and all-cause 30 day mortality was 5.5% (3 of 55 patients). One patient had a significant post-procedural aortic regurgitation of > grade 2. Symptomatic improvement was evident in most patients, with reduction in functional capacity grade from 3.2 ± 0.6 at baseline to 1.4 ± 0.7. The most common post-procedural complication was complete heart block, which necessitated permanent pacemaker implantation in 37% of patients.

Conclusions: The Israeli first year experience of transcatheter aortic valve implantation using the CoreValve self-expandable system demonstrates an effective and safe procedure for the treatment of severe aortic stenosis in patients at high surgical risk.

Background: Guidelines are frequently under-implemented in older patients with heart failure. Octogenerians are often excluded from clinical trials.

Objectives: To characterize the clinical profile of the oldest-old (age ≥ 80 years) heart failure patients hospitalized in a subacute geriatric hospital and to evaluate their management and 1 year outcome.

Methods: Patient characteristics and in-hospital course were retrospectively collected. Diagnosis of heart failure was based mainly on clinical evaluation in addition to chest X-ray results and echocardiographic findings when available.

Results: The study population comprised 96 consecutive unselected heart failure patients hospitalized from January to June 2003. The patients were predominantly women (67%), aged 85 ± 5 years, fully dependent or frail with a high rate of comorbidities. Adherence to guidelines and recommended heart failure medications was poor. Their 1 year mortality was 57%. According to logistic regression analysis, predictors of 1 year mortality were lower body mass index (odds ratio 0.86, 95% confidence interval 0.78–0.96) and high urea levels (OR[1] 1.04, 95% CI[2] 1.02–1.06).

Conclusions: Our study confirms that the management of oldest-old heart failure patients hospitalized in a subacute geriatric hospital was suboptimal and their mortality was exceptionally high.

Background: Clinical and epidemiologic features of coronary heart disease may not be explained solely by established risk factors. The role of infectious pathogens in the development and rupture of atherosclerotic plaques remains elusive but an association between Chlamydia pneumoniae, Mycoplasma pneumoniae and CHD[1] has been previously reported

Objectives: To determine whether there is an association between mycoplasmal infections and CHD.

Methods: We conducted a prospective cohort analysis of 150 consecutive hospitalized patients with CHD (85 with acute coronary syndrome and 65 admitted for unrelated reasons) and 98 healthy blood donors. Antibody titers for Mycoplasma pneumoniae, M. fermentans, M. hominis and Ureaplasma urealyticum were measured with the agglutination test or specific enzyme-linked immunosorbent assay in all three groups of patients.

Results: Analysis of the antibody titers did not reveal any significant difference in the presence of mycoplasmal antibodies between the patients with ACS[2], patients with known stable CHD hospitalized for non-CHD reasons, and healthy blood donors.

Conclusions: Determination of specific antibodies did not reveal a significant association among different types of mycoplasmal infection and CHD.

Background: Continuous use of combined oral contraceptives is currently attracting growing interest as a means of improving menstrual related symptoms and reducing the number of bleeding days.

Objectives: To evaluate bleeding patterns, menstrual symptoms and quality of life with an extended 84/7 oral contraceptive regimen versus 21/7 cycles.

Methods: In two consecutive run-in cycles, 30 µg ethinyl estradiol and 3 mg drospirenone tablets taken on days 1–21 were followed by a tablet-free period from days 22 to 28 of each cycle and then by two 84 day cycles of pill use with a 7 day tablet-free interval. The primary outcome was the total number of bleeding/spotting days. Secondary outcomes were severity of daily symptoms, general well-being determined by the PGWBI questionnaire, and overall treatment satisfaction.

Results: Of the 137 women invited to participate in the study 109 (aged 18–40 years) were enrolled. The number of bleeding days decreased by about one-third from a calculated 31.8 days of bleeding under a cyclic 21/7 regimen to an expected total of 21.8 days for the extended 84/7 regimen. The incidence of menorrhagia, intermenstrual bleeding, dysmenorrhea, abdominal bloating, breast tenderness, depressive moods and irritability – when compared at enrollment and at the end of the second extended study period – was significantly lower (P < 0.005) among women on the continuous pill regimen. The median (range) global PGWBI scores were not substantially different before and after the extended use cycles: 78.2 (39.1–96.4) and 77.3 (30.9–96.4), respectively. Body weight and skin condition also remained constant. At the completion of the study: 65.5% of the women were either highly satisfied (41.4%) or satisfied (24.1%) with the extended regimen.

Conclusions: The extended 84/7 regimen was found to be satisfactory for the majority of participants and was associated with a decrease in the number of bleeding days and an improvement in menstrual symptoms compared to 21/7 cycles. 

Background: There is controversy as to which is the preferred treatment for distal radius intra-articular fractures – anatomic reduction or external fixation.

Objectives: To evaluate the radiologic and functional outcome following external fixation of these fractures.

Methods: Between January 2003 and March 2005, 43 patients with distal radius intra-articular fractures were treated using a mini-external AO device. Follow-up of 38 of the patients included X-rays at 1 week, 6 weeks and 6 months postoperatively. The Visual Analogue Scale was used to assess pain levels, and the Lidstrom criteria scale to evaluate functional outcome and wrist motion. Clinical and radiographic results were correlated.

Results: According to the Lidstrom criteria, the results were excellent in 31%, good in 61% and fair in 5.5%; 2.5% had a poor outcome. The results of the VAS[1] were good. Thirty-five patients gained a good range of wrist movement, but 3 had a markedly reduced range. We found statistical correlation between the radiographic and clinical results, emphasizing the value of good reduction. There was no correlation between fracture type (Frykman score) and radiologic results or clinical results.

Conclusions: External fixation seems to be the preferred method of treatment for distal radius intra-articular fractures, assuming that good reduction can be achieved. The procedure is also quick, the risk of infection is small, and there is little damage to the surrounding tissues.

Background: In many hospitals a chest X-ray is performed routinely at each patient’s admission. There are scant data regarding its usefulness in contemporary patient populations, which are characterized by patients’ increasing age, severity of illness, and different comorbidities.

Methods: We studied consecutive patients admitted during a 2 month period to a single department of medicine, where hospital policy mandates performing a CXR[1] on admission or soon after. Two senior clinicians who were not involved in the care of these patients assessed the discharge summaries for a clinical indication to perform CXR on admission, as well as its contribution to patient management (major positive, major negative, minor positive, or no contribution). Logistic regression analysis was performed with the SPSS 12 software program.

Results: The study population comprised 675 patients whose mean age was 64.5 ± 17.2 years. Their presenting complaints included chest pain (18%), dyspnea (12%), weakness (10.5%), fever (9%), abdominal pain (8%) and neurologic complaints (7.5%). Physical examination of the chest was normal in 585 (87%) of the cases and abnormal in 87 (13%). Examination of the heart was normal in 518 (77%) and abnormal in 129 (19%). In 19.6% (130 cases) CXR was not performed. Of the 545 CXRs done, 260 (48%) were normal. In only 128 (23.5%) did the admission CXR make a major positive contribution to diagnosis or treatment. In 61 (11.2%) it provided a minor positive contribution and in 153 (28.1%) a major negative contribution. In 184 patients (33.8%) the CXR did not affect either diagnosis or management. It made a major positive contribution to management in patients for whom there was an indication for performing the X-ray (odds ratio 10.3, P < 0.0005) and in those with a relevant finding on physical examination (OR[2] 1.63, P = 0.110). For a major negative contribution of the CXR to management (i.e., ruling out clinically important possibilities), the clinical indication was also very important (OR 72.9, P < 0.005). When patients with either a clinical indication for performing a CXR or an abnormal chest examination were excluded, 329 patients remained (60% of the 545 who had a CXR) in only 12 of them (3.6%) did the routine admission CXR contribute to patient management.

Conclusions: A routine admission CXR has a significant impact on patient management only in those patients in whom there are relevant findings on physical examination or a clear clinical indication for performing the test. There is no need to routinely order CXR on admission to hospital.

Background: While family presence during resuscination has been researched extensively in the international and especially American medical literature, in Israel this subject has rarely been researched. Because such policies have become common practice in many countries, it is important to investigate the attitudes of health care staff in Israeli emergency departments to better understand the potential implication of adopting such policies.

Objectives: To examine the attitudes of the physicians and nurses in the ED of Soroka Medical Center to FPDR[1]. 

Methods: The methods we used were both qualitative (partly structured open interviews of 10 ED staff members from various medical professions) and quantitative (an anonymous questionnaire that collected sociodemographic, professional, and attitude data).

Results: The qualitative and quantitative results showed that most staff members opposed FPDR. The main reasons for objecting to FPDR were concern about family criticism, the added pressure that would be put on the staff members, fear of lawsuits, fear of hurting the feelings of the families, and the danger of losing one’s objectivity while treating patients. Physicians objected more strongly to FPDR than did nurses.  

Conclusions: More research is needed on FPDR in Israel, including an examination of its medical, ethical, legal and logistic aspects. In addition to the views of the medical staff, the attitudes of patients and their families should also be examined.
