Background: In the past decade, numerous new imaging and laboratory tests have been implemented that significantly contribute to improved medical diagnostic capabilities. However, inappropriate utilization, which occurs on a large scale, has significant ramifications for both patient care and health systems.

Objectives: To assess the impact of a novel clinical decision support system (CDSS) applied to our electronic medical records on abdominal ultrasonography utilization pattern.

Methods: We conducted a retrospective cohort study comparing patterns of abdominal ultrasound utilization in cases of liver enzyme elevation, with and without CDSS, between February and May in 2017 (before CDSS implementation) and during the same months in 2018 (after CDSS implementation). The following parameters were collected: number of tests ordered according to the guidelines, tests with a diagnostic value, and order forms completed with any data or a diagnostic question. The comparison was conducted using chi-square test.

Results: Of 152 abdominal ultrasound tests, 72 were ordered in the pre-implementation period and 80 in the post-implementation period. The system failed to reach statistical significance regarding the rates of ordered tests according to the guidelines and/or tests with a diagnostic value. However, the use of the CDSS had a statistically significant impact regarding completing the order form with data, including a specific diagnostic question.

Conclusions: The effect of the system on the efficiency of test utilization was partial. However, our findings strongly suggested that CDSS has the potential to promote proper usage of complementary technologies.

Background: Percutaneous dilatational tracheostomy (PDT) has become a standard technique for critically ill patients who require long-term ventilation. The most common early post-operative complication is bleeding related to anatomical variation in vasculature. The procedure is performed at the patient's bedside unless this is deemed unsafe and then the accepted alternative is open tracheostomy in the operating room. 

Objectives: To evaluate the use of pre-procedural ultrasound to aid in the decision of whether PDT in critical care patients should be performed at the patient's bedside or by open surgical tracheostomy.

Methods: Patients were jointly evaluated by a critical care physician and a head and neck surgeon. Based on this evaluation, the method of tracheostomy was determined. Subsequently, pre-procedural ultrasound examination of the anterior neck was performed. The final decision whether to perform PDT or open surgical tracheostomy was based on the ultrasound findings. Changes in management decisions following ultrasound were recorded. 

Results: We included 36 patients in this prospective study. Following ultrasound examination, the management decision was changed in nine patients (25%).

Conclusions: Pre-procedural ultrasound for critically ill patients undergoing tracheostomy can influence management decisions regarding the performance of tracheostomy.

In recent years, salivary gland ultrasonography (SGUS) has emerged as a promising tool for the diagnosis and prognostic stratification of patients with primary and secondary Sjögren’s syndrome. Several studies have emphasized that salivary ultrasonography could be a highly specific tool for the diagnosis of the disease. However, before it can be used in daily clinical practice the SGUS procedure needs standardization and validation in larger disease-control groups. In this review we provide an update on the role of SGUS in the diagnostic algorithm of primary Sjögren’s syndrome.

 Background: Goal-oriented ultrasound examination is gaining a place in the intensive care unit. Some protocols have been proposed but the applicability of ultrasound as part of a routine has not been studied.

Objectives: To assess the influence of ultrasound performed by intensive care physicians.

Methods: This retrospective descriptive clinical study was performed in a medical-surgical intensive care unit of a university-affiliated general hospital. Data were collected from patients undergoing ultrasound examinations performed by a critical care physician from January 2010 to June 2011.

Results: A total of 299 ultrasound exams were performed in 113 mechanically ventilated patients (70 males, mean age 65 years). Exams included trans-cranial Doppler (n=24), neck evaluation before tracheostomy (n=15), chest exam (n=83), focused cardiac echocardiography (n=60), abdominal exam (n=41), and comprehensive screening at patient admission (n=30). Ultrasound was used to guide invasive procedures for vascular catheter insertion (n=42), pleural fluid drainage (n=24), and peritoneal fluid drainage (n=7). One pneumothorax was seen during central venous line insertion but no complications were observed after pleural or abdominal drainage. The ultrasound study provided good quality visualization in 86% (258 of 299 exams) and was a diagnostic tool that induced a change in treatment in 58% (132 of 226 exams).

Conclusions: Bedside ultrasound examinations performed by critical care physicians provide an important adjunct to diagnostic and therapeutic performance, improving quality of care and patient safety.

Background: Fractures of the humerus in neonates can pose a diagnostic challenge, especially when the fracture occurs in the proximal or distal epiphysis.

Objectives: To review our experience in the diagnosis and treatment of birth-related humeral fractures.

Methods: Between the years 2001 and 2009, seven newborn patients and two patients treated in the neonatal intensive care unit sustained a fracture of the humerus. Four of the fractures occurred in the humeral shaft, three in the proximal epiphysis and two in the distal epiphysis. In all the newborn patients the diagnosis was made on the first day of life using radiography and ultrasonography. The fractures of the shaft and of the distal epiphysis were treated by gentle manipulation and casting, and the fractures of the proximal epiphysis were treated by swaddling.

Results: All of the patients demonstrated fracture union within 2 weeks, and radiographs at the age of 6 months demonstrated complete remodeling of the fracture.

Conclusions: Ultrasonography is a simple, readily available and inexpensive modality for the diagnosis of birth-related fractures of the humerus, especially in the yet unossified epiphyses.

Pancreatic cancer is not a common malignancy in Israel, but it is the third most common cause of cancer mortality, attributable to a lack of screening tests, inaccessibility of the pancreas, and late cancer stage at diagnosis. We reviewed the epidemiology, known risk factors and screening methods available in Israel and describe the Israeli national consortium that was established to identify persons at risk and decide on screening methods to detect and treat their early-stage pancreatic cancer. In collaboration with the Israel National Cancer Registry, we evaluated the incidence and trends of the disease in the Jewish and non-Jewish populations. The consortium reviewed known lifestyle risk habits and genetic causes, screening methodologies used and available in Israel. Overall, there are about 600 new patients per year, with the highest incidence occurring in Jewish men of European birth (age-standardized rate 8.11/105 for 2003–06). The 5 year survival is about 5%. The consortium concluded that screening will be based on endoscopic ultrasonography. Pancreatic cancer patients and families at risk will be enrolled, demographic and lifestyle data collected and a cancer pedigree generated. Risk factors will be identified and genetic tests performed as required. This concerted national program to identify persons at risk, recommend which environmental risk factors to avoid and treat, and perform endoscopic ultrasound and genetic screening where appropriate, might reduce their incidence of invasive pancreatic cancer and/or improve its prognosis

Background: Ultrasound is useful in detecting acromioclavicular pathologies in cases of trauma, inflammations and degenerative changes.

Objectives: To describe the sonographic findings of the acromioclavicular joint pathology in patients with anterior shoulder pain.

Methods: Sonographic examination of the ACJ[1] was used to examine 30 adults with anterior shoulder pain. As a control group we studied 30 asymptomatic patients and compared the findings to plain radiographs of the symptomatic group.

Results: The pathologic findings consisted of swelling of the joints, bone irregularities, widening and/or narrowing of the ACJ, soft tissue cyst formation, excessive fluid collection, and calcification. All these signs represent degenerative changes compatible with early osteoarthritis. We encountered one case of septic arthritis that required joint aspiration and antibiotic treatment.

Conclusions: It is our belief that ultrasonography should be used routinely in cases of anterior shoulder pain since it demonstrates various pathologies undetected by plain radiographs.

Background: When encountering complaints of pain in the area of the Achilles tendon, the clinician seldom reaches a correct and precise diagnosis based solely on the grounds of physical examination and standard X-rays.

Objectives: To assess the usefulness of ultrasound in diagnosing pathologies of the Achilles tendon.

Methods: We conducted a retrospective review of patients presenting at our orthopedic clinics.

Results: Sonography was used to evaluate 41 patients with achillodynia. This modality enabled the diagnoses of 19 abnormal tendons (46%), peritendinous and other lesions a complete rupture in two patients (5%) a partial rupture of the Achilles tendon in 3 (7%) various degrees of calcification of the tendon in 7 (17%) and peritendinous lesions discerned by the tendon’s hypoechoic regions with disorganized arrange­ment of collagen fibrils in 4 patients (10%). Other lesions included tendonitis (3 patients, 7%), retrocalcaneal bursitis (3 patients, 7%), lipoma (1 patient, 2%), and foreign bodies (2 patients, 5%). The mean diameter of the pathological tendons was 10.4 +2.7 mm, while normal tendons measured 5.2 +0.8 mm (P<0.001).

Conclusion: As in many other soft tissue lesions, ultrasonography is a useful tool in the evaluation of the underlying pathology in patients presenting with achillodynia.

Background: Foreign bodies are sometimes overlooked in the initial evaluation of soft tissue wounds in the emergency room setting. The physical examination identifies foreign bodies that are superficial enough to be seen or palpated, while radiographs reveal those that are radio-opaque. If these two criteria are not met, however, the foreign body may remain undetected. These patients present later with long-standing pain in the area of penetration sometimes associated with localized tenderness.

Objectives: To assess the role of ultrasonography in the diagnosis and management of patients with a suspected retained foreign body.

Methods: Ultrasound was used in 21 patients with suspected retained foreign bodies and the diagnosis was positive in 19. Fifteen underwent a surgical exploration in which the ultrasound was used as an adjunctive modality either pre- or intraoperatively to assist in the localization of the foreign body.

Results: All procedures were successful. No postoperative complications were recorded at an average follow-up of 2 years. Three patients gradually became asymptomatic and were left untreated. One patient was lost to follow-up.

Conclusion: Sonography is an extremely effective tool for the late diagnosis of retained foreign bodies in the soft tissues. We suggest that its availability in the emergency room may decrease the rate of misdiagnosis and avoid these unfortunate cases, although this remains tc be proven.
