Background: Point shear-wave elastography (pSWE) is a new method to assess the degree of liver fibrosis. It has been shown to be effective in detecting stiffness in viral hepatitis.

Objectives: To determine the feasibility of pSWE for assessing liver stiffness and fibrosis in liver diseases of different etiologies.

Methods: This prospective single-center study included a population of adult patients with chronic liver diseases from different etiologies, who were scheduled for liver biopsy, and a control group of healthy adults who prospectively underwent pSWE. Ten consecutive pSWE measurements of the liver were performed using a Philips iU22 ultrasound system. Stiffness degree was compared to liver biopsy results. Fibrosis degree was staged according to METAVIR scoring system.

Results: The study group was comprised of 202 patients who underwent liver biopsy and pSWE test and a control group consisting of 14 healthy adults who underwent pSWE for validation. In the study group, the median stiffness was 5.35 ± 3.37 kilopascal (kPa). The median stiffness for F0–1, F2, F3, and F4 as determined by liver biopsy results were 4.9 kPa, 5.4 kPa, 5.7 kPa, and 8 kPa, respectively. The median stiffness in the control group was 3.7 ± 0.6 kPa. Subgroup analyses were conducted for viral hepatitis vs. non-viral hepatitis and steatohepatitis vs. non-steatohepatitis groups.

Conclusions: pSWE is a reproducible method for assessing liver stiffness and is in a linear relationship with fibrosis degree as seen in pathology. Compared with patients with non-significant fibrosis, healthy controls showed significantly lower values

Background: There is a need for standardized and objective methods to measure postural instability (PI) and gait dysfunction in Parkinson's disease (PD) patients. Recent technological advances in wearable devices, including standard smartphones, may provide such measurements.

Objectives: To test the feasibility of smartphones to detect PI during the Timed Up and Go (TUG) test.

Methods: Ambulatory PD patients, divided by item 30 (postural stability) of the motor Unified Parkinson's Disease Rating Scale (UPDRS) to those with a normal (score = 0, PD-NPT) and an abnormal (score ≥ 1, PD-APT) test and a group of healthy controls (HC) performed a 10-meter TUG while motion sensor data was recorded from a smartphone attached to their sternum using the EncephaLog application.

Results: In this observational study, 44 PD patients (21 PD-NPT and 23 PD-APT) and 22 HC similar in age and gender distribution were assessed. PD-APT differed significantly in all gait parameters when compared to PD-NPT and HC. Significant difference between PD-NPT and HC included only turning time (P < 0.006) and step-to-step correlation (P < 0.05).

Conclusions: While high correlations were found between EncephaLog gait parameters and axial UPDRS items, the pull test was least correlated with EncephaLog measures. Motion sensor data from a smartphone can detect differences in gait and balance measures between PD with and without PI and HC.

Background: Fetal alcohol spectrum disorder is a range of disabilities caused by gestational exposure to alcohol. FASD[1] is the leading cause of preventable mental retardation and developmental disability in the United States, with an incidence of 1–10 per 1000 live births. FASD in Israel has yet to be examined systematically.

Objectives: To evaluate professionals’ experience, awareness and knowledge of FASD in Israel and their awareness of maternal consumption of alcohol, and to collect epidemiological data on the syndrome in Israel.

Methods: A short questionnaire was sent to all 43 program directors of genetic institutes (n=14) and child developmental centers in Israel (n=29). Four questions related to their experience and knowledge of FASD. The epidemiological survey included data from all 17 hospitals in Israel and from the two main health management organizations within the public health care system.

Results: The response rate was 98% (n=42). A total of 38.1% of respondents reported having diagnosed at least one case of FASD and fewer than 10% of respondents stated that the knowledge regarding FASD among physicians in Israel was adequate. Developmental pediatricians were more likely to have diagnosed at least one case as compared to geneticists. During the period 1998–2007 the diagnosis of FASD appeared in the records of only 4 patients from the total number of 17 hospitals in Israel. During the same period only six patients were diagnosed at the HMO[2] within the public health care system.

Conclusions: Despite the accumulated knowledge on FASD in many countries and the increase in alcohol consumption in Israel, professionals' awareness of its potential damage is limited. Educational programs to increase physician awareness should accompany publicity campaigns warning the public of the dangers associated with alcohol consumption during pregnancy.

Background: Concern about the side effects of allogeneic blood transfusion has led to an increased interest in methods of minimizing peri-operative transfusion. Technologies to minimize allogeneic transfusion include drugs such as aprotinin, desmopressin, tranexamic acid and erythropoietin, and techniques such as acute normovolemic hemodilution, cell salvage and autologous pre-donation.

Objective: To survey the current use in Israel of these seven technologies used to minimize allogeneic blood transfusion.

Methods: Our survey was conducted in 1996–97 in all hospitals in Israel with more than 50 beds and at least one of the following departments: cardiac or vascular surgery, orthopedics, or urology. All departments surveyed were asked: a) whether the technologies were currently being used or not, b) the degree of use, and c) the factors influencing their use and non-use. The survey was targeted at the heads of these departments.

Results: Pharmaceuticals to reduce allogeneic blood transfusion were used in a much higher proportion in cardiac surgery departments than in the other three departments. Pre-operative blood donation was used in few of the cardiac, urologic and vascular surgery departments compared to its moderate use in orthopedic departments. The use of acute normovolemic hemodilution was reported in a majority of the cardiac departments only. Moderate use of cell salvage was reported in all departments except urology where it was not used at all.

Conclusion: There is considerable practice variation in the use of technologies to minimize exposure to peri-operative allogeneic blood transfusion in Israel.
