Background: Major advances in the treatment of perinatal asphyxial–hypoxic ischemic encephalopathy followed the translation of hypothermia animal studies into successful randomized controlled clinical trials that substantially influenced the current standard of care.

Objectives: To present our preliminary experience with the first cases of clinical application of therapeutic hypothermia for PA-HIE[1] in what we believe is the first report on non-experimental hypothermia for PA-HIE from Israel.

Methods: We reviewed the medical records, imaging scans, electroencephalograms and outcome data of the six identified asphyxiated newborns who were managed with hypothermia in our services in 2008–2009.

Results: All asphyxiated newborns required resuscitation and were encephalopathic. Systemic hypothermia (33.5ºC) was begun at a median age of 4.2 hours of life (range 2.5–6 hours) and continued for 3 days. All six infants showed a significantly depressed amplitude integrated electroencephalography background, and five had electrographic seizures. One infant died (16%) after 3.5 days. Major complications included fat necrosis and hypercalcemia (n=1), pneumothorax (n=1), and meconium aspiration syndrome (n=2). None of the infants developed major bleeding. Neurodevelopmental follow-up of the five surviving infants at median age 7.2 months (4.1–18.5 months) revealed developmental delays (Battelle screening), with their motor scores ranging from -1 to +1 standard deviation (Bayley scale). None developed feeding problems, oculomotor abnormalities, spasticity or seizures.

Conclusions: Our preliminary experience with this novel modality in a large Tel Aviv neonatal service is consistent with the clinical findings of published trials.

Background: Concomitant human immunodeficiency virus and human papillomavirus infection increases both HPV[1] persistence and the risk of invasive cervical cancer. An estimation of HPV prevalence among HIV[2]-positive women in Israel would contribute to improving care for this population and preventing morbidity and mortality related to cervical cancer.

Objectives: To determine the prevalence of HPV infection and cervical cytology abnormalities, and to assess the possible influence of HIV infection on HPV carriage in HIV-positive women attending the Infectious Disease Clinic at Soroka University Medical Center.

Methods: The study population included 84 HIV-seropositive women. They were examined by a gynecologist and screened for HPV genotyping, and Pap smears were obtained for cervical cytology. Demographic, behavioral, and HIV infection variables were also recorded and analyzed.

Results: Forty-nine (58.3%) of the study participants were HPV-positive; 34 of them had oncogenic genotypes. Young age (< 16 years) at first sexual intercourse was the only variable significantly associated with HPV infection (P < 0.05). Abnormal cervical cytology was present in 17 women (20.3%); 21 women were referred to colposcopy, which was abnormal in 9 (10.7%).

Conclusions: The prevalence of HPV carriage among HIV-positive woman in our study was slightly higher than published elsewhere. The prevalence of pathological cervical cytology was much higher than in the general population. An extremely high prevalence of pathological colposcopies requiring further treatment was found. Screening for HPV and premalignant changes in the uterine cervix is highly recommended in the HIV-seropositive population. We suggest that colposcopy be considered part of the routine workup in HIV-seropositive woman.

Background: ST-elevation myocardial infarction is caused by occlusive coronary thrombosis where antecedent plaque disruption occurs. When treating STEMI[1] the main goal is to achieve prompt reperfusion of the infarction area. Several studies have demonstrated the efficacy of an aspiration device before percutaneous coronary intervention in patients with acute myocardial infarction.

Objectives: To determine the added value of thrombus aspiration prior to primary PCI[2] by comparing AMI[3] patients with totally occluded infarct-related artery treated with routine primary PCI to those treated with extraction device prior to primary PCI.

Methods: The study group comprised 122 consecutive patients with AMI and a totally occluded infarct artery (TIMI flow 0) who underwent primary PCI. The patients were divided into two groups: 68 who underwent primary PCI only (control group) and 54 who underwent primary thrombus extraction with an extraction device before PCI (extraction group). Baseline clinical and lesion characteristics were similar in both groups. Final TIMI grade flow and myocardial blush as well as 1 year mortality, target lesion revascularization, recurrent myocardial infarction, unstable angina and stroke were compared between the two groups.

Results: Primary angiographic results were better for the extraction group versus the control group: final grade 3 TIMI flow was 100% vs. 95.6% (P = 0.03) and final grade 3 myocardial blush grade 50% vs. 41.18% (although P was not significant). Long-term follow-up total MACE[4] showed a non-significant positive trend in the extraction group (12.96% vs. 24.71%, P = 0.26).

Conclusions: The use of extraction devices for intracoronary thrombectomy during primary PCI in patients with totally occluded infarct artery significantly improved epicardial reperfusion in the infarct-related vessel and showed a trend for more favorable long-term outcome.

The courts have recently become increasingly involved in the administration of compulsory psychiatric services in Israel. Data reveal a gradual increase in the rate of court-ordered hospitalizations according to Section 15 of the Law for the Treatment of the Mentally Ill. This paper examines the implications of this trend, particularly the issues of security and safety in psychiatric hospitalization. We present highlights from extensive British experience, focusing on the implications on forensic psychiatry in Israel. We review the development of the hierarchy of security in the British psychiatric services, beginning in the early 1970s with the establishment of the Butler Committee that determined a hierarchy of three levels of security for the treatment of patients, culminating with the establishment of principles for the operation of medium security units in Britain (Read Committee, 1991). These developments were the basis for the forensic psychiatric services in Britain. We discuss the relevance of the British experience to the situation in Israel while examining the current status of mental health facilities in Israel. In our opinion, a safe and suitable environment is a necessary condition for a treatment setting. The establishment of medium security units or forensic psychiatry departments within a mental health facility will enable the concentration and classification of court-ordered admissions and will enable systemic flexibility and capacity for better treatment, commensurate with patient needs.

Background: Most aspects of attention-deficit/hyperactivity disorder diagnosis rely on subjective judgment. Computerized continuous performance tests are designed to improve the validity of the process but are controversial due to low odds ratios. There is a need to find more definitive measures of assessment.

Objectives: To test the validity and reliability of a new tool, a computerized continuous performance functions test, which includes a multi-task approach designed to achieve a higher odds ratio of assessment.

Methods: We applied this test to 58 children aged 6–12 years: 45 were diagnosed as ADHD[1] and 13 non-ADHD children served as a control group.

Results: The CPF[2] test was able to differentiate between non-ADHD and ADHD children. CPF test results were more accurate than other continuous performance tests. The results were statistically significant in all test parameters, confirming the test's validity and reliability. 

Conclusions: The CPF test includes a combination of tasks based on an algorithm designed to test several domains of attention. In this pilot study the CPF test was found to be a valid and reliable tool for the diagnosis of ADHD in children. This test might increase the diagnostic utility of computerized tests. The research points to the need for developing a more definitive process for ADHD diagnosis.

The laparoscopic approach to the treatment of colon and rectal cancer was controversial long after it was accepted for benign conditions. Laparoscopic cancer resection should meet appropriate oncologic standards and achieve a long-term oncologic outcome at least equivalent to that of open resection. Several international randomized controlled trials have provided adequate data to ascertain the oncologic quality of laparoscopic colon resection, showing a benefit in short-term outcome over open resection. The use of laparoscopic resection for rectal cancer is awaiting further investigation.

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.
