Background: Group A Streptococcus (GAS), the predominant bacterial pathogen of pharyngitis, is sometimes difficult to distinguish clinically from viral pharyngitis. Despite the high prevalence of viral pharyngitis in children, antibiotic treatment is common.

Objective: To investigate the effectiveness of an antibiotic stewardship program (ASP) on antibiotic prescription in children with GAS pharyngitis (GAS-P) at a large pediatric community clinic.

Methods: Antibiotic prescription data were collected from October 2016 to March 2017 (pre-intervention period) and from October 2017 to March 2018 (post-intervention period). The intervention was a one-day seminar for primary care pediatricians on the diagnosis and treatment of GAS-P in children according to national guidelines.

Results: The overall prevalence of testing differed between the two time periods. There was a decrease in children who did not undergo any testing (from 68% to 63%), an increase in streptococcal rapid antigen detection testing (28% to 32%), and a slight increase in throat cultures (3% to 4%) (p = 0.02). There was no change in the types of antibiotics prescribed before and after the intervention (p = 0.152).

Conclusions: The ASP resulted in a slight reduction in the percentage of children who did not undergo laboratory testing for GAS-P and a slight reduction in the percentage of children who received antibiotic treatment. The ASP did not reduce the use of broad-spectrum antibiotics and macrolides.

Twenty years after being closed due to unfavorable results, a new lung transplant program was started at the Sheba Medical Center. The new team included an experienced lung transplant surgeon, an anesthesiologist, an intensive care specialist, and a pulmonologist with extensive experience in the field.

Background: Traditionally, the task of health promotion and early detection screening has been the purview of health maintenance organizations through the family physician. For some years, it has become popular for private health organizations to offer a concentrated day of comprehensive medical testing, which is promoted as a perk by many organizations to their employees. What do these programs offer? Are the tests that are offered evidence based?

Objectives: To describe a concentrated day of comprehensive medical testing program in view of current evidence base medicine (EBM) recommendations.

Methods: We reviewed official internet sites of the most popular concentrated days of comprehensive medical testing and compared the tests offered to the recommendation of several Israeli and international guidelines.

Results: Many tests performed at director screening days do not follow EBM recommendations. Tests like mammography, colonoscopy, bone density, and prostate-specific antigen tests are often offered outside of the recommended age and risk groups and without pretest consultation.

Conclusions: We recommend against routine general health examinations for healthy adults. The most important treatment is not screening and early detection but real prevention. We recommend turning these director screening days into real investments in future health by changing the focus from diagnosis to treatment through prevention. One-on-one conversations, explanations, and most importantly tools to encourage lifestyle changes, will really make a difference.

Background: Achieving laparoscopic competency is challenging. Common laparoscopic simulators usually fall short in achieving true simulation.

Objective: To present a live porcine model laparoscopic skills laboratory for training general surgery residents.

Methods: An in vivo porcine laparoscopic model course was developed to simulate seven different laparoscopic procedures and seven laparoscopic skills for trainees under the tutelage of laparoscopic specialists.

Results: A total of 98 surgical trainees from 19 training programs underwent a full-day course from September 2017 to July 2020. Each program consisted of four trainees and two faculty members. In total, 175 laparoscopic procedures were performed. Trainees reported that the course improved their ability to perform in the operating room.

Conclusions: Using a laparoscopic porcine model in a guided didactic course performing complete common laparoscopic procedures in simulated operating room surroundings was beneficial for surgical trainees. The porcine model mimics human abdominal anatomy and allows trainees to increase their comfort level in performing such procedures.

Background: With diagnostic imaging, such as a duplex of the carotid arteries, finding of stenosis and atherosclerotic plaque and consequent end arterectomy may be important for decreasing the danger of developing cerebrovascular accident after transient ischemic attack (TIA).

Objectives: To measure performance rates of duplex of carotid arteries within 72 hours of TIA diagnosis.

Methods: The denominator included all patients who were admitted to emergency departments because of TIA, and the numerator included those who underwent duplex within 72 hours of admission. Inclusion criteria included all patients older than 18 years who were admitted because of TIA according to the ICD9 codes.

Results: Measuring this indicator started in 2015 with 5504 patients and a 58% success rate. The figures for the years 2016, 2017, and 2018 were 5309, 5447, and 5278 patients with success rates of 73%, 79%, and 83%, respectively. Six of 26 hospitals (23.0%) reached the target of 80% in 2018. From 2015 to 2018 a total of 21,538 patients were admitted to emergency departments in Israel and diagnosed with TIA. Of these, 15,722 (72.9%) underwent duplex within 72 hours. The mortality rate within 30 days from diagnosis was 0.81% in patients who performed duplex within 72 hours of diagnosis and 2.37% in patients who did not, odds ratio 2.676, 95% confidence interval 2.051–3.492, P < 0.0001. These results indicate a statistically significant decrease of 65.82%.

Conclusions: A significant decrease in mortality was noted in patients with a new diagnosis of TIA who underwent duplex within 72 hours of diagnosis

Background: Ophthalmic pathologies may further complicate the sensory input of patients with congenital hearing loss; however, data on children with coexisting impairment of vision and hearing is outdated, from before universal implementation of hearing screening programs.

Objectives: To examine the different ophthalmic pathologies among children with congenital sensorineural hearing loss (SNHL) before or after the introduction of a universal newborn hearing screening program (UNHSP).

Methods: Retrospective cohort study was conducted of 91 children diagnosed with congenital SNHL between 2005 and 2016 in a tertiary pediatric hospital. All patients completed an ophthalmologic examination, including assessment of visual acuity, refraction, ocular motility, slit lamp examination, and indirect funduscopy. Radiological assessment and genetic analysis were offered to all caregivers.

Results: Average age at diagnosis was 4.1 years. Nineteen children (21%) were diagnosed with an ophthalmic condition, of which the most common were refractive pathologies. Diagnosis of an ophthalmic pathology was twice as likely in the pre-UNHSP era (14 children, 27%) compared to the post-UNHSP era (5 children, 13%). Out of 91 children, 57 (63%) underwent a computed tomography scan and/or magnetic resonance imaging. Imaging was positive for structural abnormalities in 23 children (40%). There was no correlation between imaging and ophthalmic conditions. Genetic analysis was performed in 67 patients (74%).

Conclusions: The ophthalmic assessment of babies and children with congenital SNHL may yield in significant numbers of children with concomitant ophthalmic pathologies. Implementation of a UNHSP allows early diagnosis and treatment of coexisting ophthalmic and hearing conditions.

Background: Multidisciplinary biopsychosocial rehabilitation for patients presenting with rheumatic diseases has been shown to produce better results in a warm climate. Dead Sea Climatotherapy (DSC) has been successfully used for decades to treat many patients with rheumatic diseases.

Objectives: To evaluate the short-term improvement of Norwegian patients who presented with chronic pain following a multidisciplinary biopsychosocial approach to treatment combined with DSC. Both objective and subjective clinical parameters were evaluated.

Methods: This retrospective study included a statistical analysis of 938 patients presenting with rheumatoid arthritis and ankylosing spondylitis (n=105), osteoarthritis (n=342), fibromyalgia (n=374), and other orthopedic conditions (n=117). Clinical assessments were conducted before and after a 3 week treatment program at the Dead Sea.

Results: Six parameters improved significantly in the rheumatoid arthritis and ankylosing spondylitis group as well as in the osteoarthritis group. Five parameters in the fibromyalgia group improved, while two improved in the orthopedic conditions group. Overall, major significant changes occurred in the pain self-assessment, joint motility, and daily activities scores.

Conclusions: A 3-week multidisciplinary biopsychosocial program combined with DSC induced positive changes in the clinical parameters of Norwegian patients presenting with chronic musculoskeletal pain.

Background: About half of all patients with heart failure are diagnosed with heart failure preserved ejection fraction (HFpEF). Until now, studies have failed to show that medical treatment improves the prognosis of patients with HFpEF.

Objectives: To evaluate changes in exercise capacity of patients with HFpEF compared to those with heart failure with reduced ejection fraction (HFrEF) following an exercise training program.

Methods: Patient data was retrieved from a multi-center registry of patients with heart failure who participated in a cardiac rehabilitation program. Patients underwent exercise testing and an echocardiogram prior to entering the program and were retested6  months later.

Results: Of 216 heart failure patients enrolled in the program, 170 were diagnosed with HFrEF and 46 (21%) with HFpEF. Patients with HFpEF had lower baseline exercise capacity compared to those with HFrEF. Participating in a 6 month exercise program resulted in significant and similar improvement in exercise performance of both HFpEF and HFrEF patients: an absolute metabolic equivalent (MET) change (1.45 METs in HFrEF patients vs. 1.1 in the HFpEF group, P = 0.3).

Conclusions: An exercise training program resulted in similar improvement of exercise capacity in both HFpEF and HFrEF patients. An individualized, yet similarly structured, cardiac rehabilitation program may serve both heart failure groups, providing safety and efficacy.

Background: The authors describe a multifaceted cross-infection control program that was implemented to contain an epidemic of multidrug-resistant microorganisms (MRO) (carbapenem resistant Pseudomonas aeruginosa and Acinetobacter baumannii; extended spectrum β-lactamase producing Klebsiella pneumoniae, Escherichia coli, Enterobacter Cloacae, and Proteus mirabilis; and ‎methicillin-resistant Staphylococcus aureus and Candida species). 

Objectives: To assess the effect of a control program on the incidence of cross-infection with MRO.

Methods: Clinical criteria triaged patients into a high-risk wing (HRW) or a low-risk wing (LRW). Strict infection control measures were enforced; violations led to group discussions (not recorded). Frequent cultures were obtained, and use of antibiotics was limited. Each quarter, the incidence of MRO isolation was reported to all staff members. 

Results: Over a 6 year period, 1028 of 3113 patients were placed in the HRW. The incidence of MRO isolation within 48 hours of admission was 8.7% (HRW) vs. 1.91% (LRW) (P < 0.001). Acquired MRO infection density was 30.4 (HRW) vs. 15.6 (LRW) (P < 0.009). After the second year, the incidence of group discussions dropped from once or twice a month to once or twice a year.

Conclusions: These measures contained epidemics. Clinical criteria successfully triaged HRW from LRW patients and reduced cross-infection between the medical center wings. The quarterly reports of culture data were associated with improved staff compliance. MRO epidemic control with limited resources is feasible. 

 

Background: Human dignity has a pivotal role within the health care system. There is little experience using simulation-based medical education (SBME) programs that focus on human dignity issues in doctor-patient relationships.

Objectives: To describe and assess a SBME program aimed at improving physicians’ competence in a dignifying approach when encountering adolescents and their parents.

Methods: A total of 97 physicians participated in 8 one-day SMBE workshops that included 7 scenarios of typical adolescent health care dilemmas. These issues could be resolved if the physician used an appropriate dignifying approach toward the patient and the parents. Debriefing discussions were based on video recordings of the scenarios. The effect of the workshops on participants’ approach to adolescent health care was assessed by a feedback questionnaire and on 5-point Likert score questionnaires administered before the workshop and 3 months after. 

Results: All participants completed both the pre-workshop and the feedback questionnaires and 41 (42%) completed the post-workshop questionnaire 3 months later. Practice and competence topics received significantly higher scores in post-workshop questionnaires (P < 0.001). A score of high to very high was given by 90% of physicians to the contribution of the workshop to participants understanding the dignifying approach, and by 70% to its influence on their communicative skills.

Conclusions: A one-day simulation-based workshop may improve physicians’ communication skills and sense of competence in addressing adolescents’ health care issues which require a dignifying approach toward both the adolescent patients and their parents. This dignity-focused methodology may be expanded to improve communication skills of physicians from various disciplines. 

 

Background: Children dependent on gastrostomy tube feeding and those with extremely selective eating comprise the most challenging groups of early childhood eating disorders. We established, for the first time in Israel, a 3 week intensive weaning and treatment program for these patients based on the "Graz model."

Objectives: To investigate the Graz model for tube weaning and for treating severe selective eating disorders in one center in Israel. 

Methods: Pre-program assessment of patients’ suitability to participate was performed 3 months prior to the study, and a treatment goal was set for each patient. The program included a multidisciplinary outpatient or inpatient 3 week treatment course. The major outcome measures were achievement of the target goal of complete or partial tube weaning for those with tube dependency, and expansion of the child's nutritional diversity for those with selective eating. 

Results: Thirty-four children, 28 with tube dependency and 6 with selective eating, participated in four programs conducted over 24 months. Their mean age was 4.3 ± 0.37 years. Of all patients, 29 (85%) achieved the target goal (24 who were tube-dependent and 5 selective eaters). One patient was excluded due to aspiration pneumonia. After 6 months follow-up, 24 of 26 available patients (92%) maintained their target or improved. 

Conclusions: This intensive 3 week program was highly effective in weaning children with gastrostomy tube dependency and ameliorating severe selective eating. Preliminary evaluation of the family is necessary for completion of the program and achieving the child’s personal goal, as are an experienced multidisciplinary team and the appropriate hospital setup, i.e., inpatient or outpatient. 

 

The progression from standard celluloid films to digitalized technology led to the development of new software programs to fulfill the needs of preoperative planning. We describe here preoperative digitalized programs and the variety of conditions for which those programs can be used to facilitate preparation for surgery. A PubMed search using the keywords “digitalized software programs”, “preoperative planning” and “total joint arthroplasty” was performed for all studies regarding preoperative planning of orthopedic procedures that were published from 1989 to 2014 in English. Digitalized software programs are enabled to import and export all picture archiving communication system (PACS) files (i.e., X-rays, computerized tomograms, magnetic resonance images) from either the local working station or from any remote PACS. Two-dimension (2D) and 3D CT scans were found to be reliable tools with a high preoperative predicting accuracy for implants.  The short learning curve, user-friendly features, accurate prediction of implant size, decreased implant stocks and low-cost maintenance makes digitalized software programs an attractive tool in preoperative planning of total joint replacement, fracture fixation, limb deformity repair and pediatric skeletal disorders.

Abstract

During recent months, the Centers for Disease Control and Prevention (CDC) announced the occurrence of three major biosafety incidents, raising serious concern about biosafety and biosecurity guideline implementation in the most prestigious agencies in the United States: the CDC, the National Institutes of Health (NIH) and the Federal Drug Administration (FDA). These lapses included: a) the mishandling of Bacillus anthracis spores potentially exposing dozens of employees to anthrax; b) the shipment of low pathogenic influenza virus unknowingly cross-contaminated with a highly pathogenic strain; and c) an inventory lapse of hundreds of samples of biological agents, including six vials of variola virus kept in a cold storage room for decades, unnoticed. In this review we present the published data on these events, report the CDC inquiry’s main findings, and discuss the key lessons to be learnt to ensure safer scientific practice in biomedical and microbiological service and research laboratories.
