While postoperative pain management was shown to reduce unwanted physiological and emotional outcomes, pediatric postoperative pain management remains suboptimal. Medical-clowns were shown to be beneficial in many medical contexts including reduction of stress, anxiety and pain. This study was set to assess the effectiveness of medical-clowns on pediatric postoperative pain reduction. Children age 4 or above, planned for elective hernia repair surgery were recruited. Children were randomly divided to a control or medicalclown escorted groups. Demographical and clinical data were collected using questionnaires and electronic sheets. Children escorted by clowns reported lower levels of pain upon admittance, discharge and 12-hours post-surgery. Statistically significant reduction of parental distress and significantly higher serum cortisol levels were observed in the clown-therapy group. Although small, our study supports the possibility that preoperative medical-clown therapy might be a cheap, safe and yet beneficial method for postoperative pain reduction.

Background: The aetiology of conotruncal heart defects is poorly understood and the birth prevalence varies geographically. The known risk factors for developing conotruncal heart defects are as follows: CHD in siblings, genetic chromosomal abnormalities, paternal age >30 years, high parity, low birth weight, prematurity, and maternal diabetes.Objective: The aim of this study was to characterise conotruncal heart defects, birth prevalence, mortality, and morbidity in the population of southern Israel, of whom 75% are Jewish and the rest are mostly Bedouin Arabs.Methods: The data were obtained from Soroka University Medical Center database of births and newborns. Conotruncal heart defects cases were identified by ICD9 codes.Results: During 1991–2011, there were 247,290 singleton live births and 393 conotruncal heart defects in Soroka University Medical Center. The birth prevalence per 10,000 live births of tetralogy of Fallot, transposition of the great arteries, and truncus arteriosus was 9.5, 5, and 1.8, respectively. In the multivariate analysis, Bedouin descent (adjusted odds ratio 2.40, p35 years (1.66, p=0.004), and siblings with congenital heart defects (1.98, p=0.005) were associated with tetralogy of Fallot, and Bedouin descent (1.61, p=0.05), siblings with congenital heart defects (2.19, p=0.004), and diabetes mellitus (7.15, p<0.001) were associated with transposition of the great arteries. In a univariate analysis, Bedouin descent (p=0.004) and congenital heart defects in siblings (p<0.001) were associated with truncus arteriosus.Conclusion: We observed higher birth prevalence of conotruncal heart defects compared with the birth prevalence reported worldwide, specifically among the Bedouins, a population characterised with high consanguinity rate. Therefore, genetic counselling and early fetal echocardiograms should be encouraged, especially in high consanguinity rate populations. Naturally, further educational efforts are needed in order to decrease consanguinity and its related consequences.

Background: Congenital Heart Defects (CHD) are the most common structural defects of newborns. Southern Israel’s population is comprised of Jews (75%) and Arab-Bedouins (25%). The latter has a high rate of consanguinity and low abortion rate compared with the Jewish population, which led us to suspect a higher CHD prevalence in this population. Our aim was to compare maternal risk factors that are associated with CHD in these populations.Methods: All births during 1991–2011 in Soroka University Medical Center (n = 247, 289) with 6078 newborns having CHD were included. To account for same-woman deliveries, general estimating equation models adjusted for ethnicity, gender and birth number were used.Results: The total prevalence of CHD was 24.6/1000 live births, with 21.4 and 30 among Jewish and Bedouin populations, respectively, (p = 0.001). Multi-variant analysis of risk factors for CHD revealed that risk factors common to both populations included conception with fertility medications, sibling CHD, maternal CHD, diabetes mellitus, hypertension and anaemia. Risk factors that were specific for the Bedouin population were – maternal age over 35 years, recurrent pregnancy loss and in vitro fertilisation. However, sibling CHD was more common as a CHD risk factor in the Jewish compared with the Bedouin population (Adjusted OR 10.23 versus 3.19, respectively).Conclusions: The prevalence of CHD is higher in both the Bedouin and Jewish populations than previously reported. Several maternal factors were associated with CHD specifically for a certain population. Risk factors for CHD vary in populations residing in the same geographic area.

Background: Eliminating the need for a preoperative spine CT scan prior to spine surgery offers significant financial advantages, reduced radiation exposure, and a more streamlined workflow. This can be achieved by converting a standard-protocol MRI scan into a synthetic CT (sCT), which provides a precise representation of bone structures. The sCT is intended for use in the preoperative planning and navigation of spine surgeries, eliminating the need for an additional CT scan. Methods: The transformation is based on a neural network architecture that converts MRI data into high-resolution sCT images. Although the resolution of standard magnetic resonance imaging ranges from 3 to 5 mm, sCT achieves sub-millimeter accuracy (below 1 mm). In this study, we present the results of the generation of sCT and compare them with conventional CT scans of the same patients. Results: A comprehensive comparison was conducted using both 3D and 2D measurements on 500 different vertebrae. The 3D evaluation used 3D surface distance measurement to assess the full vertebrae and key anatomical elements. The 2D analysis focused on critical distances that define the vertebral body, pedicles, and spinous processes. All measurements were performed automatically and validated by orthopedic surgeons, ensuring clinical relevance. Conclusions: This study shows that converting a standard-protocol MRI scan into an sCT provides a precise representation of bone structures.

Background: Patients with ankylotic spines suffering from vertebral column fractures are frequently operated on to maintain spinal stability and prevent secondary displacement and nerve damage. The aim of this study was to identify a subset of patients that may be treated non-operatively, thus avoiding operative complications in this group of patients. Methods: Extension-type injuries in patients with DISH (diffuse idiopathic skeletal hyperostosis) not involving the posterior elements of the spine comprised the study group. Results: Twenty two extension fractures occurred in 21 patients with DISH in SZMC (Shaare Zedek Medical Cente) between 2014–2025. All patients were treated non-operatively. Patients were allowed free mobilization, and no orthosis was used. The only limitation was keeping the bed inclined to 20–30 degrees to prevent extension at the fracture site. All fractures healed uneventfully, and no patient required late surgical intervention, and no neurological complications were noted. Conclusions: Patients with DISH who sustain extension-type injuries of the thoracolumbar spine, with no involvement of the posterior elements, may be treated non-operatively, with good results.
