Background: For health professionals who interact professionally with children, adequate awareness and training regarding the clinical indicators of child abuse and neglect, as well as subsequent reporting and procedures, are essential.

Objectives: To study Israeli health professionals’ experiences with identification and reporting of suspected cases of child abuse and neglect, and their perceived training needs in this area.

Methods: The study group was a convenience sample comprising 95 Israeli health professionals (physicians, nurses, social workers, psychologists, etc.) attending workshops on medical aspects at a national conference on child abuse and neglect. The study was a cross-sectional survey. The health professionals were asked to complete an anonymous structured questionnaire on their experience with child abuse and neglect and on their training needs.

Results: The participants in the survey had relatively high levels of involvement with child protection. Nevertheless, they strongly expressed their need for training, especially in mastering practice skills. The need for training was greater for professionals with less experience in child protection, and there were different needs according to profession.

Conclusions: Despite their prior extensive experience in dealing with child abuse and neglect, most of the health professionals participating in the conference reported the need for training in various areas.

Background: Previous pregnancies may influence the success of medical termination of pregnancy.

Objectives: To determine the effect of parity and gravidity on the successful termination of pregnancy using mifepristone and misoprostol.

Methods: The medical files of all patients attending a department of obstetrics and gynecology during the years 2006 and 2007 for the purpose of medical termination of pregnancy at ≤ 49 days of gestation were analyzed retrospectively. The medical history, previous pregnancies and deliveries were recorded. Mifepristone was administered orally followed by 400 mg of misoprostol 48 hours later. A second dose of misoprostol was offered 2 weeks later if uterine content thickness was more than 15 mm. Then, after 24 hours, if uterine content thickness was more than 15 mm the uterus was evacuated by dilation and curettage.

Results: Of 403 women, 349 (86.6%) aborted following the basic regime; 207 (51.4%) (group A) were primiparous while 196 (48.6%) (group B) had at least one prior pregnancy. Uterine curettage was performed in 17 patients (8.2%) in group A and in 37 (18.9%) in group B (P = 0.002). When patients with a history of a previous abortion were excluded from group B, 32 of 143 (22.4%) required curettage (P < 0.001). When patients without a history of previous cesarean section were excluded, 10 of 52 (19.2%) underwent curettage (P = 0.038).

Conclusions: Previous pregnancies negatively affect the success of medical termination of pregnancy, especially in women with a previous term pregnancy. This information is important when counseling women about the method of pregnancy termination.
 

Background: Little is known of the outcome of pregnant patients with previously diagnosed dilated cardiomyopathy. These patients are usually firmly advised against continuation of the pregnancy.

Objectives: To examine the usefulness of serial echocardiographic follow-up and plasma N-terminal pro-B type natriuretic peptide levels in the management of pregnant women with preexisting DCM[1].

Methods: We prospectively enrolled pregnant women with DCM either known or diagnosed in the first trimester. Clinical examination and serial echocardiography studies at baseline, 30 weeks gestation, peripartum, and 3 and 18 months postpartum were performed. Blinded NTproBNP[2] levels were obtained at 30 weeks, delivery and 3 months postpartum.

Results: Between June 2005 and October 2006 we enrolled seven women who fulfilled the study criteria. Delivery and postpartum were complicated in 3 patients (42%): 2 with acute heart failure, which resolved conservatively, and 1 with major pulmonary embolism. The left ventricular ejection fraction was stable throughout the pregnancy (35% ± 2.8 at baseline, 33% ± 2.9 at 30 weeks) and postpartum (35% ± 2.8 at 1 day, 34% ± 3.1 at 90 days). Similar stable behavior was observed regarding left ventricular dimensions: LV[3] end-systolic diameters 43.3 ± 2.7 mm and LV end-diastolic diameters 57.3 ± 3.3 mm at baseline compared with 44.1 ± 3.1 mm and 58.7 ± 3.1 mm postpartum, respectively. The NT-ProBNP levels rose significantly peripartum in all three patients with complications.

Conclusions: Serial NT-proBNP levels, as compared to echocardiography, may be a better clinical tool in monitoring and management of pregnant women with preexisting DCM. An early rise in NT-ProBNP level appears to predict the occurrence of adverse events.

Background: A pandemic (H1N1) influenza A virus was identified in 2009.

Objectives: To investigate predictors for pandemic (H1N1) 2009 virus infection among hospitalized patients with a flu-like illness and to identify parameters suggesting a severe clinical course.

Methods: We analyzed a cohort of all patients hospitalized during a 2 month period with a flu-like syndrome who were tested for pandemic (H1N1) 2009 infection. Demographic, clinical and laboratory, along with outcome parameters, were recorded and compared between pandemic (H1N1) 2009 virus-positive and negative hospitalized patients.

Results: Of the 179 examined hospitalized patients suspected of having pandemic (H1N1) 2009 infection 65 (36%) were found positive. These patients tended to be younger and had significantly fewer comorbidities. In addition, they had a significantly higher frequency of fever (94%), cough (86%) and myalgia (29%). Furthermore, age < 65 years and cough were independent predictors for pandemic (H1N1) 2009 virus positivity in a multivariate regression analysis. Notably, 14 of the 65 positive patients (21.5%) had acute respiratory insufficiency requiring treatment in the intensive care unit. These patients were neither older nor previously sicker than patients with non-severe disease, but were distinguished by augmented inflammatory markers, significant lymphopenia associated with disease severity, and overall mortality of 21.4%.

Conclusions: Pandemic (H1N1) 2009 virus-positive hospitalized patients tend to be younger and have fewer comorbidities as compared to compatible negative patients. A significant number of relatively young and previously healthy positive patients might develop severe disease associated with a robust inflammatory reaction and significant lymphopenia.

The introduction of novel targeted therapies into the clinic in recent years has had a considerable impact on the management of several neoplastic diseases – such as gastrointestinal stromal tumors, hepatocellular carcinomas and renal cell carcinomas – considered until recently refractory to systemic therapies. We describe here two such novel biological agents, sunitinib and sorafenib, as a paradigm of the successful clinical application of new concepts. Sunitinib and sorafenib are small molecule tyrosine kinase inhibitors that target vascular endothelial growth factor receptor, platelet-derived growth factor receptor, C-Kit and others. Both agents are administered orally; sunitinib is typically given in cycles for 4 consecutive weeks with 2 weeks off, while sorafenib is given continually. Side effects occur in most patients, similar for both agents; they may affect several systems and organs but are mostly mild and easily manageable, rarely requiring discontinuation of the drug. However, these toxicities require prompt attention and intervention. The most frequently observed effects are hypertension, nausea, anorexia, asthenia and cutaneous manifestations; cardiac abnormalities may include congestive failure. Sunitinib, and markedly less frequently sorafenib, may cause thyroid gland dysfunction, mainly hypothyroidism. Antitumor activity has been shown for renal cell carcinoma in pivotal trials, for sunitinib as first-line treatment and for sorafenib in previously treated patients as second-line. Sunitinib is now approved as second-line therapy for patients with GIST[1] refractory to imatinib; sorafenib has resulted in a significant prolongation in median survival in patients with hepatocellular carcinoma. Ongoing clinical trials will further define the spectrum of these agents' antitumor activity, their role in combination with other drugs, as well as their optimal dose and schedule of administration.

Background: A survey conducted among Israel Defense Force primary care physicians in 2001 revealed that they consider patients' needs more than they do organizational needs and that the education PCPs[1] currently receive is inadequate. In 2003 the medical corps initiated a multi-format continuous medical education program aimed at improving skills in primary care medicine.

Objectives: To measure and analyze the effect of the tailored-made CME[2] program on PCPs’ self-perception 3 years after its implementation and correlate it to clinical performance.

Methods: In 2006 a questionnaire was delivered to a representative sample of PCPs in the IDF[3]. The questionnaire included items on demographic and professional background, statements on self-perception issues, and ranking of roles. We compared the follow-up survey (2006) to the results of the original study (2001) and correlated the survey results with clinical performance as measured through objective indicators.

Results: In the 2006 follow-up survey PCPs scored higher on questions dealing with their perception of themselves as case managers (3.8 compared to 4.0 on the 2001 survey on a 5 point scale, P = 0.046), perceived quality of care and education (3.5 vs. 3.8, P = 0.06), and on questions dealing with organizational commitment (3.5 vs. 3.8, P=0.01). PCPs received higher scores on clinical indicators in the later study (odds ratio 2.05, P < 0.001).

Conclusions: PCPs in the IDF perceive themselves more as case managers as compared to the 2001 survey. A tailor-made CME program may have contributed to the improvement in skills and quality of care.

Background: Professional volunteers play a crucial role in reinforcing emergency medical services in Israel. In order to encourage volunteers to return for additional shifts, the organization should provide conditions that will assure the return, particularly at a time of self-risk such as war. In 2009 Israeli emergency medical services (Magen David Adom) were required to increase preparedness in the southern part of the country due to missile attacks on civilian populations, while continuing their routine activities, i.e., responding promptly to emergency events. In order to perform these multiple functions, MDA[1] stations in the towns under attack were strengthened with volunteers from other regions of the country. These volunteers, trained as paramedics, served in 24–48 hour shifts.

Objectives: To identify the factors influencing the willingness of volunteers to return.

Methods: A questionnaire was used to assess the satisfaction of volunteers participating in the reinforcement with regard to their physical environment, job assignment and the actual activity they were involved in. Data were analyzed using SPSS statistical software.

Results: During the 10 days of the study, 121 volunteers reinforced southern MDA stations and 99 (81%) of them responded to the questionnaire. We found that volunteers' willingness to return to do more shifts was affected by their welcome and reception at the station, their job assignment, and their training and preparation for performing the necessary tasks. The sleeping conditions and the number of events they participated in were also contributing factors.

Conclusions: Factors that contribute to the willingness of volunteers to re-volunteer should be taken into account by organizations that rely on them.

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.

survey. A tailor-made CME program may have contributed to the improvement in skills and quality of care.

Background: Ultrasound examination of the fetus enables diagnosis of many major malformations during pregnancy, providing the possibility to consider interruption of the pregnancy. As a result, in many cases the incidence of malformations at birth does not represent their true incidence.

Objectives: To determine the impact of prenatal diagnosis and termination of pregnancy on the relative incidence of malformations at birth among Jews and Muslim Arabs in Israel.

Methods: Data on selected major malformations in 2000–2003 were collected from the two large central databases of the Ministry of Health and the Central Bureau of Statistics which contain information regarding births, stillbirths and terminations of pregnancies.

Results: For many malformations the total incidence was much higher than the incidence at birth. For almost all of the malformations studied, the total incidence was higher in Muslims than in Jews and the differences were further accentuated among the liveborn because of the differences in the rate of pregnancy terminations.

Conclusions: In order to detect possible influences of environmental or genetic factors on major malformations in Israel, it is critical to look at data including pregnancy terminations, stillbirths and live births.

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: Patients with multiple (< 100) colorectal adenomatous polyps are at increased risk for colorectal cancer. Genetic evaluation of those patients who test negative for APC gene mutation is both a clinical and economic burden but is critical for counseling and surveillance. In Israel, this is confounded by the fact that national health insurance does not fully cover genetic evaluation of APC gene exon 16.

Objectives: To perform a comprehensive genetic evaluation of APC gene mutation-negative polyposis patients with the aim of developing a future evaluation protocol.

Methods: Genetic analyses were performed in 29 APC gene mutation-negative Jewish individuals with 5 to ≥ 40 colonic adenomas who did not fulfill Amsterdam (clinical) criteria for Lynch syndrome. Analyses included completion of APC gene exon 16 sequencing, analysis for APC gene copy number variations (deletions or duplications), MUTYH gene sequencing, and microsatellite instability in CRC[1] patients fulfilling “Bethesda” (laboratory investigation) criteria for Lynch syndrome.

Results: Completion of APC gene exon 16 sequencing revealed one patient with the E1317Q polymorphism. All were normal by APC multiplex ligation-dependent probe amplification analysis. Pathogenic MUTYH mutations were found in three patients, all of North African origin; two additional patients had variants of unknown significance. One of six patients with Bethesda-positive criteria was MSI²-High with immunohistology consistent with MLH1 mutation.

Conclusions: Based on this small but well-characterized cohort with multiple colorectal adenomas, Lynch syndrome needs to be excluded if there are compatible criteria; otherwise MUTYH sequencing is probably the first step in evaluating APC-negative patients, especially for Jews of North African descent. Completing APC exon 16 sequencing and copy number variations analysis should probably be the last evaluations.
