Background: Evaluation of children's anthropometrics poses challenges due to age-related changes. The main focus is on height and weight. However, since weight is height-dependent, body mass index (BMI) is the best surrogate measurement of adiposity. Israel has not developed national growth tables; therefore, researchers and clinicians utilize either World Health Organization (WHO) or U.S. Centers for Disease Control and Prevention (CDC) tables as benchmarks.

Objectives: To evaluate the anthropometrics of Israeli children benchmarked by CDC and WHO tables.

Methods: A retrospective review was conducted of the 1987–2003 birth cohort (age 4–18 years) from Clalit Health Services databases. Anthropometrics were retrieved twice: at study entry and one year later. We evaluated them as separate cohorts. Gender-specific age-matched median height and BMI were compared with CDC and WHO height and BMI tables.

Results: The study consisted of 15,650, mean age at study entry 9.5 years (range 4–18). Gender-specific median heights of the Israeli children were similar to CDC and WHO values at younger ages, but were slightly shorter than the age-matched CDC and WHO toward the age of final height in both cohorts. However, gender-specific median BMI was considerably and statistically significant higher compared to CDC and WHO values consistently along the entire age range in both cohorts.

Conclusions: Israeli children were slightly shorter toward the age of final height, compared to WHO and CDC. However, BMI in Israeli children was significantly higher compared to the CDC and WHO consistently along the age range, which raises an alarm regarding obesity patterns

Background: Hypomagnesemia (serum magnesium level < 1.7 mg/dl) occurs more frequently in patients with type 2 diabetes mellitus (T2DM).Serum magnesium levels are not routinely tested in hospitalized patients, including in hospitalized patients with T2DM.

Objectives: To evaluate the prevalence of hypomagnesemia among hospitalized T2DM patients treated with proton pump inhibitors (PPIs) and/or diuretics.

Methods: A total of 263 T2DM patients hospitalized in general departments were included in the study and were further divided into four groups: group 1 (patients not treated with PPIs or diuretics), group 2 (patients treated with PPIs), group 3 (patients treated with diuretics), and group 4 (patients treated with both PPIs and diuretics).  Blood and urine samples were taken during the first 24 hours of admission. Electrocardiogram was performed on admission.

Results: Of the 263 T2DM patients, 58 (22.1%) had hypomagnesemia (serum magnesium level < 1.7 mg/dl). Patients in group 2 had the lowest mean serum magnesium level (1.79 mg/dl ± 0.27). Relatively more patients with hypomagnesemia were found in group 2 compared to the other groups, although a statistically significant difference was not observed. Significantly more patients in group 3 and 4 had chronic renal failure. Patients with hypomagnesemia had significantly lower serum calcium levels.

Conclusions: Hospitalized T2DM patients under PPI therapy are at risk for hypomagnesemia and hypocalcemia

Background: Pancreatic trauma is uncommon in pediatric patients and presents diagnostic and therapeutic challenges. While non-operative management (NOM) of minor pancreatic injuries is well accepted, the management of major pancreatic injuries remains controversial.

Objectives: To evaluate management strategies for major blunt pancreatic injury in children.

Methods: Data were retrospectively collected for all children treated for grade III or higher pancreatic injury due to blunt abdominal trauma from 1992 to 2015 at two medical centers. Data included demographics, mechanism of injury, laboratory and imaging studies, management strategy, clinical course, operative findings, and outcome.

Results: The cohort included seven boys and four girls aged 4–15 years old (median 9). Six patients had associated abdominal (mainly liver, n=3) injuries. The main mechanism of injury was bicycle (handlebar) trauma (n=6). Five patients had grade III injury and six had grade IV. The highest mean amylase level was recorded at 48 hours after injury (1418 U/L). Management strategies included conservative (n=5) and operative treatment (n=6): distal (n=3) and central (n=1) pancreatectomy, drainage only (n=2) based on the computed tomography findings and patient hemodynamic stability. Pseudocyst developed in all NOM patients (n=5) and two OM cases, and one patient developed a pancreatic fistula. There were no differences in average length of hospital stay.

Conclusions: NOM of high-grade blunt pancreatic injury in children may pose a higher risk of pseudocyst formation than OM, with a similar hospitalization time. However, pseudocyst is a relatively benign complication with a high rate of spontaneous resolution with no need for surgical intervention.

Background: The coronavirus disease-2019 (COVID-19) crisis has affected how hospitals work and has had an effect on orthopedic surgery.

Objectives: To compare patient management and low-energy and high-energy trauma treatment at two orthopedic trauma units during the COVID-19 crisis and to clarify resource demands and preparedness in orthopedic clinics during the state of emergency caused by the COVID-19 pandemic.

Methods: This retrospective study was conducted at two orthopedic trauma units from 14 March 2019 to 14 April 2019 and from 14 March 2020 to 14 April 2020.

Results: The proportion of patients admitted in the multi-trauma orthopedic unit decreased by one-third, the mean time interval from admission to surgery significantly decreased, and the number of surgeries and mean length of stay in hospital decreased in 2020 compared to the same test period in 2019. In the orthopedic trauma unit, the number of patients and surgeries also decreased.

Conclusions: Our study highlights changes in orthopedic injury characteristics in two orthopedic units during the COVID-19 crisis in Latvia and compares these changes to data from the same time period one year earlier.

Background: The novel coronavirus disease (COVID-19) pandemic changed medical environments worldwide.

Objectives: To evaluate the impact of the COVID-19 pandemic on trauma-related visits to the emergency department (ED).

Methods: A single tertiary center retrospective study was conducted that compared ED attendance of patients with injury-related morbidity between March 2020 (COVID-19 outbreak) and pre-COVID-19 periods: February 2020 and the same 2 months in 2018 and 2019.

Results: Overall, 6513 patients were included in the study. During the COVID-19 outbreak, the daily number of patients visiting the ED for acute trauma declined by 40% compared to the average in previous months (P < 0.01). A strong negative correlation was found between the number of trauma-related ED visits and the log number of confirmed cases of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in Israel (Pearson's r = -0.63, P < 0.01). In the COVID-19 period there was a significant change in the proportion of elderly patients (7% increase, P = 0.002), admissions ratio (12% increase, P < 0.001), and patients brought by emergency medical services (10% increase, P < 0.001). The number of motor vehicle accident related injury declined by 45% (P < 0.01).

Conclusions: A significant reduction in the number of trauma patients presenting to the ED occurred during the COVID-19 pandemic, yet trauma-related admissions were on the rise

Background: Patients with critical limb ischemia (CLI) involving the below-the-knee (BTK) arteries are at increased risk of limb loss. Despite improvement in endovascular modalities, it is still unclear whether an aggressive approach results in improved limb salvage.

Objectives: To assess whether an aggressive approach to BTK arterial disease results in improved limb salvage.

Methods: A comparative study of two groups was conducted. Group 1 included patients treated between 2012 and 2014, primarily with transfemoral angioplasty of the tibial arteries. Group 2 included patients treated between 2015–2019 with a wide array of endovascular modalities (stents, multiple tibial artery and pedal angioplasty, retrograde access). Primary endpoint was freedom from amputation at 4 years.

Results: A total of 529 BTK interventions were performed. Mean age was 71 ± 10.6 years, 382 (79%) were male. Patients in group 1 were less likely to be taking clopidogrel (66% vs. 83%, P < 0.01) and statins (72 % vs. 87%, P < 0.01). Several therapeutic modalities were used more often in group 2 than in group 1, including pedal angioplasty (24 vs. 43 %, P = 0.01), tibial and pedal retrograde access (0 vs. 10%, P = 0.01), and tibial stenting (3% vs. 25%, P = 0.01). Revascularization of two or more tibial arteries was performed at a higher rate in group 2 (54% vs. 50%, P = 0.45). Estimated freedom from amputation at 40 months follow-up was higher in group 2 (53% vs. 63%, P = 0.05).

Conclusions: An aggressive, multimodality approach in treating BTK arteries results in improved limb salvage.

Background: Injuries to the anterior cruciate ligament (ACL) are common and complete tears often fail to heal. ACL reconstruction is considered the surgical gold standard of care for ACL injuries in young active patients.

Objectives: To determine the corresponding morphological and histological features of the torn ACL in different time periods after injury.

Methods: The study included 28 remnant specimens of torn ACLs from patients who had ACL reconstruction surgery of the knee. The remnant pathology was evaluated by its morphology during arthroscopy and by histopathologic measurements.

Results: At surgery there were three progressive and distinct morphological tear patterns. The first pattern was noticed within the first 3 months from injury and showed no scar tissue. The second pattern appeared later and was characterized by the appearance of scar tissue with adhesion to the femoral wall. The third pattern was characterized by adhesion of the ACL remnant to the posterior cruciate ligament. The histological changes of the first morphological pattern showed abundance of blood vessels and lymphocytes at the torn femoral end with few irregular collagen fibers. The second and third tear patterns showed decrement in the number of blood vessels and lymphocytes with longitudinally oriented collagen fibers.

Conclusions: The morphological features of the ACL remnant in the first 3 months after injury showed no scar tissue and its histological features had the characteristics of a reparative phase. This phase was followed by a prolonged remodeling phase that ended with attachment of the remnant to the posterior cruciate ligament.

Background: Patients diagnosed with coronavirus disease-19 (COVID-19) who deteriorate to respiratory failure and require mechanical ventilation may later need to be weaned from the ventilator and undergo a rehabilitation process. The rate of weaning COVID-19 patients from mechanical ventilation is unknown.

Objective: To present our experience with ventilator weaning of COVID-19 patients in a dedicated facility.

Methods: A retrospective cohort study was conducted of 18 patients hospitalized in a COVID-19 dedicated ventilator weaning unit.

Results: Eighteen patients were hospitalized in the dedicated unit between 6 April and 19 May 2020. Of these, 88% (16/18) were weaned and underwent decannulation, while two patients deteriorated and were re-admitted to the intensive care unit. The average number of days spent in our department was 12. There was no statistically significant correlation between patient characteristics and time to weaning from ventilation or with the time to decannulation.

Conclusions: Despite the high mortality of COVID-19 patients who require mechanical ventilation, most of the patients in our cohort were weaned in a relatively short period of time. Further large-scale studies are necessary to assess the cost effectiveness of dedicated COVID-19 departments for ventilator weaning.

Background: Primary spontaneous pneumothorax (PSP) tends to occur in young adults without underlying lung diseases and is usually followed by limited symptoms, while secondary spontaneous pneumothorax (SSP) is a complication of a pre-existing lung disease. Surprisingly, for such common conditions, there is a considerable inconsistency regarding management guidelines.

Objectives: To evaluate the risk factors for spontaneous pneumothoraxes and to summarize outcomes and complications based on our clinical experience.

Methods: This retrospective study group was comprised of 250 consecutive patients older than 18 years of age who were diagnosed with spontaneous pneumothorax and hospitalized at the Meir Medical Center (2004–2017). Data on demographic characteristics, indicating symptoms, chest X-rays, and chest computed tomography (CT) results were collected. Our experience and outcomes were then compared to a large multicenter study.

Results: Most of the patients were male (85%) and past or current smokers; 69% presented with PSP, while the rest were SSP. No occupational relation was noted. About 55% of the cases presented with a moderate or large pneumothorax (over 1/3 hemithorax). Most patients (56%) required chest tube drainage and 20% undergone surgery. Nearly 10% presented with a recurrent pneumothorax with the mean time to recurrence being 11 ± 20 days. Although the length of hospital stay of patients that underwent surgery was the longest (P < 0.001) for both PSP and SSP, the recurrence rate was actually reduced, suggesting some benefit for the surgical treatment option.

Conclusions: Our experience showed that the traditional approach to the PSP treatment should be further considered, as previously suggested.

Background: Vitamin D is essential for skeletal health. Because peak bone mass accrual occurs during childhood and adolescence, vitamin D insufficiency during this period of life could cause adverse health outcomes.

Objectives: To explore the potential sex differences in anthropometric indicators and vitamin D status among primary school-age children.

Methods: A modified food-frequency intake questionnaire was completed by 116 pre-pubertal children (52 girls, 64 boys). Body measurements were recorded and blood was drawn to assess vitamin D status. All children were of Arab-Israeli origin and lived in villages or rural areas in the north-east area of Israel.

Results: Prevalence of obesity was higher among girls (34%) compared to boys (21.9%, P = 0.018). All the children were vitamin D insufficient, and 80% were deficient. Plasma vitamin D was significantly higher among boys (12.4 ng/ml) compared to girls (9.1 ng/ml, P < 0.01). A significant negative correlation was found between vitamin D status and weight percentile for girls (r = -0.43, P < 0.05) but not for boys. There was a trend toward a statistically significant inverse correlation between vitamin D status and body fat percent in the girls (r = -0.37, P = 0.07). Sex frameworks are important for the understanding of the determinants of health and the development of effective health promotion programs.

Conclusions: Pre-pubertal girls in Arab villages should be provided with tailor-made nutrition and physical activity programs for promoting health.
