Background: Multiple myeloma (MM) affects the long bones in 25% of patients. The advent of positron-emission tomography/computed tomography (PET/CT) scanners offers the possibility of both metabolic and radiographic information and may help determine fracture risk. To the best of our knowledge, no published study correlates these two factors with long bone fractures.

Objective: To evaluate the impact of PET/CT on fracture risk assessment in multiple myeloma patients.

Methods: We identified all bone marrow biopsy proven multiple myeloma patients from 1 January 2010 to 31 January 2015 at a single institution. We prospectively followed patients with long bone lesions using PET/CT scan images.

Results: We identified 119 patients (59 males/60 females) with 256 long bone lesions. Mean age at diagnosis was 58 years. The majority of lesions were in the femur (n=150, 59%) and humerus (n=84, 33%); 13 lesions in 10 patients (8%) required surgery for impending (n=4) or actual fracture (n=9). Higher median SUVmax was measured for those with cortical involvement (8.05, range 0–50.8) vs. no involvement (5.0, range 2.1–18.1). SUVmax was found to be a predictor of cortical involvement (odds ratio = 1.17, P = 0.026). No significant correlation was found between SUVmax and pain or fracture (P = 0.43).

Conclusions: Improved medical treatment resulted improvement in 8% of patients with an actual or impending fracture. The orthopedic surgeons commonly use the Mirels classification for long bone fracture prediction. Adding PET/CT imaging to study in myeloma long bone lesions did not predict fracture risk directly but suggested it indirectly by cortical erosion.

Background: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column.

Objectives: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter.

Methods: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio.

Results: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not.

Conclusions: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter

Background: In recent years, treatment for Achilles tendon rupture (ATR) went through radical changes: from the conservative non-weight bearing approach to a functional protocol. This functional protocol allows complete weight bearing after only 2 weeks by placing the foot in a plastic boot in tapered down equines and using interchangeable wedges under the heel. This change of approach has dramatically lowered the rate of re-rupture.

Objectives: To describe our preliminary results with this functional protocol and to assess outcome measures in the functional conservative treatment.

Methods: The study comprised 15 people who were evaluated clinically and by sonograph. We measured calf circumference, ankle joint range of motion (ROM), and single-leg heel-rise test (SLHRT). In addition, standard scoring methods (Achilles Tendon Rupture Score and Physical Activity Scale) were examined.

Results: In our cohort 14 people successfully gained SLHRT. The mean Achilles Tendon Rupture Score functional questionnaire and Physical Activity Scale physical activity questionnaire score was 85.6 of 100, and 4.7 of 6, respectively. There were no significant differences in ankle ROM compared to the uninjured limb. There was statistically significant reduction in the calf circumference and soleus muscle thickness sonographically.

Conclusions: It seems that the conservative functional treatment of ATR demonstrates good functional outcomes, with the patients returning to close to normal activity, although noted muscle wasting and weakness. This protocol presents a true alternative to surgery and should be considered for most non-insertional Achilles tendon tears

Background: Acute extremity compartment syndrome is a surgical emergency for which timely diagnosis is essential.

Objectives: To assess whether the time from the initial insult to the fasciotomy of compartment syndrome of the upper extremity affects outcomes and to examine the differences between compartment syndrome secondary to fractures and that resulting from a non-fracture etiology with regard to the time from insult to fasciotomy and the long-term patient outcomes.

Methods: Patients presented with documented fasciotomy treatment following acute upper extremity compartment syndrome and a minimum of 6 months follow-up. Patient information included demographics, cause of compartment syndrome, method of diagnosis, and outcome on follow-up.

Results: Our study was comprised of 25 patients. Fasciotomies were performed for compartment syndrome caused by fracture in 11 patients (44%), and due to insults other than fractures in 14 patients (56%). The average time to fasciotomy in patients without a fracture was 10.21 hours and 16.55 hours with a fracture. Fasciotomy performed more than 24 hours from the initial insult was not found to significantly affect long-term sequelae compared to fasciotomy performed earlier than 24 hours from the initial insult. The non-fracture group had more long-term sequelae than the fracture group (13/15 patients and 5/11 patients, respectively).

Conclusions: Most injuries treated for fasciotomy of compartment syndrome were non-fracture related, with more complications found in patients with non-fracture related injuries. Time interval from insult to fasciotomy did not affect outcome and was longer in the fracture group, suggesting longer monitoring in this group and supporting fasciotomy even with late presentation.

Background: Cervical spinal surgery is considered safe and effective. One of the few specific complications of this procedure is C5 nerve root palsy. Expressed primarily by deltoid muscle and biceps brachii weakness, it is rare and has been related to nerve root traction or to ischemic spinal cord damage.

Objectives: To determine the clinical and epidemiological traits of C5 palsy. To determine whether C5 palsy occurs predominantly in one specific surgical approach compared to others.

Methods: A retrospective study of patients who underwent cervical spine surgery at our medical center during a consecutive 8-year period was conducted. The patient data were analyzed for demographics, diagnosis, and surgery type and approach, as well as for complications, with emphasis on the C5 nerve root palsy.

Results: The study group was comprised of 124 patients. Seven (5.6%) developed a C5 palsy following surgery. Interventions were either by anterior, by posterior or by a combined approach. Seven patients developed this complication. All of whom had myelopathy and were older males. A combined anteroposterior (5 patients) and posterior access (2 patients) were the only approaches that were associated with the C5 palsy. None of the patients who were operated via an anterior approach did develop this sequel.

Conclusions: The incidence of the C5 root palsy in our cohort reached 5.6%. Interventions performed through a combined anterior-posterior access in older myelopathic males, may carry the highest risk for this complication

Diagnosis and treatment of posterior hip pain has increased due to advancements in clinical, anatomical, biomechanical, and related pathological understandings of the hip. Due to its complexity and close anatomical relationship with many osseous, neurovascular, and musculotendinous structures, posterior hip pain must be appropriately categorized based on its origin. Therefore, it is crucial that clinicians are able to determine whether patient complaints are of extra-articular or intra-articular nature so that they can implement the optimal treatment plan. In the current review article, we discussed posterior hip pain with an emphasis on the main differential diagnoses of deep gluteal syndrome, ischiofemoral impingement, and hamstring tear/hamstring syndrome. For the appropriate diagnosis and etiology of posterior hip pain, a thorough and conclusive clinical history is imperative. Physicians should rule out the possibility of spinal involvement by physical examination and if necessary, by magnetic resonance imaging (MRI). Furthermore, because of the vicinity to other, non-orthopedic structures, an obstetric and gynecologic history, general surgery history, and urologic history should be obtained. Following the collection of patient history clinicians should adhere to an established and efficient order of evaluation starting with standing then to seated, supine, lateral, and prone testing. Imaging assessment of posterior hip pain begins with a standard anterior-posterior pelvic radiograph, in addition to frog-leg lateral. MRI is pivotal for assessing soft tissue-related extra-articular causes of hip in patients with posterior hip pain. Non-surgical treatment is preferred in most cases of deep gluteal syndrome, ischiofemoral impingement, pudendal nerve entrapment, and proximal hamstring pathologies. Surgical treatment is saved as a last resort option in cases of failed non-surgical treatment

Background: The coronavirus disease-2019 (COVID-19) pandemic forced drastic changes in all layers of life. Social distancing and lockdown drove the educational system to uncharted territories at an accelerated pace, leaving educators little time to adjust.

Objectives: To describe changes in teaching during the first phase of the COVID-19 pandemic.

Methods: We described the steps implemented at the Technion–Israel Institute of Technology Faculty of Medicine during the initial 4 months of the COVID-19 pandemic to preserve teaching and the academic ecosystem. 

Results: Several established methodologies, such as the flipped classroom and active learning, demonstrated effectiveness. In addition, we used creative methods to teach clinical medicine during the ban on bedside teaching and modified community engagement activities to meet COVID-19 induced community needs. 

Conclusions: The challenges and the lessons learned from teaching during the COVID-19 pandemic prompted us to adjust our teaching methods and curriculum using multiple online teaching methods and promoting self-learning. It also provided invaluable insights on our pedagogy and the teaching of medicine in the future with emphasis on students and faculty being part of the changes and adjustments in curriculum and teaching methods. However, personal interactions are essential to medical school education, as are laboratories, group simulations, and bedside teaching

Background: Our hospital used to perform cesarean delivery under general anesthesia rather than neuraxial anesthesia, mostly because of patient refusal of members of the conservative Bedouin society. According to recommendations implemented by the Israeli Obstetric Anesthesia Society, which were implemented due to the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, we increased the rate of neuraxial anesthesia among deliveries.

Objectives: To compare the rates of neuraxial anesthesia in our cesarean population before and during SARS-CoV-2 pandemic.

Methods: We included consecutive women undergoing an elective cesarean delivery from two time periods: pre-SARS-CoV-2 pandemic (15 February 2019 to 14 April 2019) and during the SARS-CoV-2 pandemic (15 February 2020 to 15 April 2020). We collected demographic data, details about cesarean delivery, and anesthesia complications.

Results: We included 413 parturients undergoing consecutive elective cesarean delivery identified during the study periods: 205 before the SARS-CoV-2 pandemic and 208 during SARS-CoV-2 pandemic. We found a statistically significant difference in neuraxial anesthesia rates between the groups: before the pandemic (92/205, 44.8%) and during (165/208, 79.3%; P < 0.0001).

Conclusions: We demonstrated that patient and provider education about neuraxial anesthesia can increase its utilization. The addition of a trained obstetric anesthesiologist to the team may have facilitated this transition

Background: Psoriatic arthritis (PsA) is an inflammatory rheumatic disease characterized by different phenotypes in terms of joint involvement. The so-called oligoarticular pattern involves fewer than five active joints at a different time points. The evaluation of disease activity in this subset of patients is an unmet need due to the lack of specific indices able to capture modifications over time.

Objectives: To evaluate the ability of musculoskeletal ultrasound to monitor the response to apremilast treatment in oligoarticular PsA patients.

Methods: We evaluated 24 oligoarticular patients (19 women, 5 men; median age 56 years, interquartile range (IQR) 19; median disease duration 5 years, IQR 5.75). All patients were assessed at baseline (T0), and after 6 (T1), 12 (T2), and 24 (T3) weeks. Clinical assessment included evaluation of 66 swollen joints and patient global health assessment. All the patients underwent ultrasound assessment of the clinically involved joints. Synovial effusion/hypertrophy and power Doppler were scored with a semi-quantitative scale (0–3). The total inflammatory score was the sum of the scores.

Results: We found a reduction in the ultrasound inflammatory score at all time points, with a significant improvement at 6 and 12 weeks of treatment compared with baseline: T0 median 8.5 (IQR 5.0); T1 3.5 (3.0); T2 2.0 (3.5); P  = 0.01. We observed a significant reduction of patient global health assessment after 24 weeks (T0 median 50 (32.5); T3 40 (57.5); P = 0.01).

Conclusions: Musculoskeletal ultrasound could be useful in the assessment of treatment response in PsA patients with oligoarticular subset

Background: Adenovirus infections are prevalent in children. They usually cause a mild self-limited disease. However, this infection can be associated with considerable morbidity and mortality in specific populations, especially among immunocompromised children. Children with Down syndrome are susceptible to a higher frequency and increased severity of viral infections. Little is known about the severity and clinical course of adenovirus infections in children with Down syndrome.

Objectives: To characterize hospitalized children diagnosed with Down syndrome and presenting with adenovirus infection.

Methods: We performed a retrospective review of children admitted with adenovirus from January 2005 to August 2014 from a single tertiary pediatric medical center in Israel. Data were compared between patients with and without Down syndrome.

Results: Among the 486 hospitalized children with adenoviral infection, 11 (2.28%) were diagnosed with Down syndrome. We found that children with Down syndrome were more likely to experience a higher incidence of complications (18.2% vs. 2.4%, P = 0.008), a higher rate of admissions to the intensive care unit (36.4% vs. 2.4%, P < 0.001), and more prolonged hospitalizations (17 ± 15.9 days compared to 4.46 ± 3.16, P = 0.025).

Conclusions: Children with Down syndrome who were hospitalized with adenovirus infection represent a high-risk group and warrant close monitoring. If a vaccine for adenovirus becomes available, children with Down syndrome should be considered as candidates

Background: Syncope is a common reason for emergency department (ED) visits; however, the decision to admit or discharge patients after a syncopal episode remains challenging for emergency physicians. Decision rules such as the Boston Syncope Criteria have been developed in an attempt to aid clinicians in identifying high-risk patients as well as those who can be safely discharged, but applying these rules to different populations remains unclear.

Objectives: To determine whether the Boston Syncope Criteria are valid for emergency department patients in Israel.

Methods: This retrospective cohort convenience sample included patients who visited a tertiary care hospital in Jerusalem from August 2018 to July 2019 with a primary diagnosis of syncope. Thirty-day follow-up was performed using a national health system database. The Boston Syncope Criteria were retrospectively applied to each patient to determine whether they were at high risk for an adverse outcome or critical intervention, versus low risk and could be discharged.

Results: A total of 198 patients fulfilled the inclusion criteria and completed follow-up. Of these, 21 patients had either an adverse outcome or critical intervention. The rule detected 20/21 with a sensitivity of 95%, a specificity of 66%, and a negative predictive value of 99%.

Conclusions: The Boston Syncope Criteria may be useful for physicians in other locations throughout the world to discharge low-risk syncope patients as well as identify those at risk of complications

Background: Decisions on medication treatment in children dying from cancer are often complex and may result in polypharmacy and increased medication burden. There is no information on medication burden in pediatric cancer patients at the end of life (EOL).

Objectives: To characterize medication burden during the last hospitalization in children dying from cancer

Methods: We performed a retrospective cohort study based on medical records of 90 children who died from cancer in hospital between 01 January 2010 and 30 December 2018. Demographic and clinical information were collected for the last hospitalization. We compared medication burden (number of medication orders) at hospitalization and at time of death and examined whether changes in medication burden were associated with clinical and demographic parameters.

Results: Median medication burden was higher in leukemia/lymphoma patients (6 orders) compared to solid (4 orders) or CNS tumor patients (4 orders, P = 0.006). Overall, the median number of prescriptions per patient did not change until death (P = 0.42), while there was a significant reduction for some medication subgroups (chemotherapy [P = 0.035], steroids [P = 0.010]).Patients dying in the ICU (n=15) had a higher medication burden at death (6 orders) than patients dying on wards (3 orders, P = 0.001). There was a trend for a reduction in medication burden in patients with “Do not resuscitate” (DNR) orders (P = 0.055).

Conclusions: Polypharmacy is ubiquitous among pediatric oncology patients at EOL. Disease type and DNR status may affect medication burden and deprescribing during the last hospitalization.
