In the last hundred years, the science of fracture repair has significantly changed. Management has moved from a simple metabolic and hormonal concept of bone regeneration to an inflammatory concept and now to a more complicated immunological description. Fracture repair has been considered age-dependent and related to diabetes, nutrition, hormone connection, autoimmune diseases, rheumatic arthritis, and nicotine. Recently a new branch of medicine, osteoimmunology, which deals with the mechanism of fracture repair, has been introduced.

Background: Patients with mechanical prosthetic heart valves must be treated with vitamin K antagonists (VKA) due to an increased risk of valve thrombosis and systemic embolism.

Objectives: To assess the effects of the COVID-19 pandemic on VKA treatment control in patients with mechanical prosthetic heart valves.

Methods: We conducted a retrospective nationwide cohort study using the Clalit Health Services database. The cohort included patients who underwent either aortic or mitral valve replacement using a prosthetic mechanical valve. The primary outcomes included the overall time in therapeutic range (TTR) and the percent of patients with a TTR < 50% during the first year of the COVID-19 pandemic compared to preceding year.

Results: The cohort included 2381 patients. The percentage of patients who had at least two international normalized ratio (INR) tests during the first year of the COVID-19 pandemic was significantly lower compared to the year preceding the pandemic (81% and 87%, respectively, P < 0.001). In both years, the percentage of patients without any documented INR test was high (31.5% in the first COVID-19 pandemic year and 28.9% in the preceding year, P < 0.001). TTR was significantly lower during the 1st year of the COVID-19 pandemic compared to the preceding year (68.1% ± 26 and 69.4% ± 24, P = 0.03). A TTR > 50% was demonstrated in 78% and 81% during the pandemic and the preceding year, P = 0.009.

Conclusions: We noted overall poor VKA control in patients with mechanical heart valves. During the COVID-19 pandemic, VKA control became even worse as reflected by significantly lower TTR and INR tests rates.

Background: Cloacal malformation represents the rarest and most complex congenital anorectal malformation in females and is characterized by the convergence of urinary, gynecological, and intestinal systems within a single common channel. Three-dimensional computed tomography reconstruction (3D CT cloacagram) has emerged as a valuable method for anatomical assessment and preoperative planning.

Objectives: To evaluate our experience with 3D CT cloacagram and assess its results.

Methods: This retrospective case series included all patients with cloacal malformation who underwent preoperative 3D CT cloacagram at a single institution during 2019–2023. Collected data included patient characteristics, timing of the 3D CT cloacagram, results of the 3D CT cloacagram, comparison with endoscopic results, surgical procedures, and postoperative outcome.

Results: Six patients with cloacal malformation were included in this study, including two with posterior cloaca. The median common channel length on 3D CT cloacagram was 24.5 mm (range 9–48 mm) and the median urethral length was 15.5 mm (range 13-24 mm). The surgical approach involved a combined abdominoperineal approach in three patients and posterior sagittal anorectal vaginal urethral plasty in one patient. Two patients were awaiting surgical reconstruction at the time of publication.

Conclusions: Our implementation of 3D cloacagram has facilitated precise measurements of both the urethra and common channel lengths, two key factors in formulating surgical strategies for cloacal reconstruction. Moreover, this technique has markedly improved our capacity for surgical planning contributing to colorectal, gynecological, and urological perspectives.

Background: Breech presentation is a major indication for cesarean delivery (CD); however, the ideal timing of breech CD is debatable.

Objectives: To study the influence of gestational age at the time of CD in breech presentation on maternal and fetal complications.

Methods: We conducted a retrospective study including term singleton CDs of breech presentation between February 2020 and January 2022 at a tertiary medical center. Maternal and neonatal outcomes were compared by gestational age at the time of CD. Logistic regression models were constructed to adjust for confounders.

Results: The study population included 468 CDs, 227 (48.5%) were at 37 + 0 to 38 + 6 weeks, 168 (36%) were at 39 + 0 to 39 + 6 weeks (comparison group), and 73 (15.5%) were at ≥ 40 weeks at the time of delivery. The rate of emergent CDs was significantly higher in both study groups. The composite of maternal adverse outcomes was also significantly higher at ≥ 40 weeks of gestation. Using logistic regression model, associations remained significant. The adjusted odds ratios (OR) for emergent CDs at 37 + 0 to 38 + 6 weeks and at ≥ 40 weeks were 1.65 (P = 0.018) and 2.407 (P = 0.004), respectively. Adjusted OR for maternal adverse outcomes at ≥ 40 weeks was 2.094 (P = 0.018). Higher rates of emergent CDs in both study groups compared to the comparison group was noted. A composite of maternal adverse outcomes was significantly higher at ≥ 40 weeks of gestation. This association remained significant after controlling for potential confounders.

Conclusions: CDs at 39 + 0 to 39 + 6 weeks are associated with better maternal outcomes and lower rates of emergent CDs.

Background: Galactin-3 has been found to be involved in oocyte maturation, folliculogenesis, implantation, and placentation. The expression of Galactin-3 in the endometrium of women who have successfully undergone in vitro fertilization (IVF) has been suggested as a potential biomarker for predicting successful embryo implantation.

Objectives: To evaluate the expression of Galactin-3 in the sera and follicular fluid of women during IVF cycles.

Methods: This prospective research included 21 women undergoing IVF treatments. Blood samples were taken at four points: day 2 before starting stimulation, trigger day, day of oocyte retrieval, and day of the β-human chorionic gonadotropin level test. In addition, follicular fluid samples were taken on the day of oocyte retrieval. Galactin-3 protein levels were measured in serum and follicular fluid using enzyme-linked immunosorbent assay.

Results: Galactin-3 levels on the stimulation day were positively correlated to estradiol levels on the day of the trigger (0.59, P = 0.02). Among women who achieved pregnancy compared to those who did not, Galectin-3 serum levels were higher on the day of the trigger (17.93 ± 4.35 ng/ml vs. 11.01 ± 3.73 ng/ml, P = 0.015).

Conclusions: These findings may imply a potential role of Galectin-3 on the success of IVF treatments, underscoring the potential importance of inflammatory processes in fertility.

Background: Diabetic ketoacidosis (DKA) poses a significant medical emergency in both type 1 (T1DM) and type 2 diabetes mellitus (T2DM) patients. Recent attention has focused on the emergence of euglycemic DKA associated with sodium-glucose cotransporter-2 (SGLT2) inhibitors.

Objectives: To understand the epidemiology and outcomes of DKA, particularly in T2DM patients.

Methods: We conducted a retrospective cohort analysis of 204 patients admitted with DKA to Shamir Medical Center (2013–2021). We assessed demographics, clinical characteristics, and outcomes. Patients were stratified by diabetes type and SGLT2 inhibitor treatment status.

Results: Among the 204 patients with DKA, 38.2% had T2DM. Patients with T2DM exhibited older age, higher co-morbidity burden, and greater prevalence of microvascular complications compared to T1DM patients. Mortality rates were notably higher among T2DM patients, despite similar DKA severity at presentation, including in-hospital mortality rates of 6.4% vs. 0%, P < 0.05, and 90-day mortality rates of 7.7% vs. 0%, P < 0.05. T2DM was independently associated with adverse hospitalization outcomes, including a composite of rehospitalization, prolonged hospital stays, and mortality (odds ratio 2.68, 95% confidence interval 1.302–5.557). SGLT2 inhibitor treatment did not affect hospitalization outcomes of patients with T2DM.

Conclusions: Our findings underscore the importance of recognizing DKA as a substantial complication in diabetic patients, particularly those with T2DM. Vigilance in management, adherence to DKA guidelines, and awareness of triggers such as SGLT2 inhibitors are crucial for improving outcomes in this population.

Background: Clinical toxicology is not a certified specialty in Israel, consequently there are a limited number of toxicologists and toxicology services available for consultation.

Objectives: To establish a medical toxicology consultation service focusing on bedside consultations, which had not previously been available in Israel.

Methods: This single-center, retrospective chart review of toxicology consults was conducted during the first years after the initiation of a new toxicology service.

Results: From September 2017 to December 2021, 1703 toxicology consultations were conducted. The most common exposures and reasons for consultation included psychotropic medications (427, 23%), analgesics and anti-inflammatory medications (353, 19%), household products (312, 17%), substances of abuse (240, 13%), and natural toxins (142, 8%). Bedside medical toxicology consultations were performed in 1036 cases (62%) during daytime and night shifts. The number of consultation requests increased steadily over the study period.

Conclusions: The new toxicology service led to a significant change in the institution’s approach to toxicological patients. A bedside toxicology service could help reduce the healthcare burden on national poison centers and can offer readily available, personalized, medical toxicology care.

Background: Serum ferritin is a sensitive inflammatory biomarker reflecting cell damage and oxidative stress in inflammatory rheumatic diseases. The use of ferritin for assessment of systemic sclerosis (SSc) activity, severity, and prognosis has not been fully elucidated.

Objectives: To assess the correlation between serum ferritin levels and SSc disease parameters, complications, and outcome.

Methods: Demographic, clinical, and laboratory data, including blood levels of ferritin, were collected from files of patients with SSc who were treated at the Rheumatology Institute at Rambam Health Care Campus from January 2004 to July 2021. The study compared SSc patients with elevated levels of ferritin to those with normal levels.

Results: We extracted data of 241 SSc patients (80% female, 60% with diffuse SSc, mean age 54 ± 15.4 years, mean disease duration 6.8 ± 4.5 years). During follow-up, 39% died. Elevated ferritin levels positively correlated with male sex; short disease duration; lung, heart, and kidney involvement; higher modified Rodnan skin score; anemia; elevated levels of creatinine kinase, C-reactive protein, creatinine, and troponin; reduced pulmonary function tests (forced vital capacity and diffusion capacity of the lung for carbon monoxide); and left ventricular ejection fraction. There were no correlations between ferritin levels and pulmonary hypertension or gastrointestinal involvement. Levels of ferritin negatively correlated with anti-centromere antibodies.

Conclusions: In SSc, ferritin can serve as a marker for ongoing systemic inflammation and prognosis, particularly in patients with lung and heart involvement. Further studies on serial ferritin measurement in the management of SSc patients are warranted.

We report a rare case of an epidural abscess caused by Aggregatibacter aphrophilus in a 69-year-old healthy woman. The patient, presented with neck pain, high fever, and chills following dental treatment. A magnetic resonance imaging (MRI) scan revealed an epidural abscess with moderate spinal cord compression at the C4–C5 level. Surgical intervention and antibiotic therapy with ceftriaxone led to complete recovery. This case underscores the significance of considering A. aphrophilus as a potential pathogen in patients with neck pain and fever post-dental procedures and as a cause of abscesses in apparently healthy patients.

A. aphrophilus, a gram-negative coccobacillus, is part of the HACEK group (Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, Kingella), a group of bacteria mainly known for its association with endocarditis [1]. However, A. aphrophilus is an uncommon pathogen for epidural abscesses [2]. Our case illustrates its potential to cause an epidural abscess after dental manipulation.

Kidney involvement in systemic sclerosis (SSc) is common with altered kidney function present in approximately half of the patients [1]. Scleroderma renal crisis (SRC), the most severe kidney manifestation, occurs in about 20% of patients with this autoimmune disorder [1]. SRC mainly affects patients with the diffuse cutaneous systemic sclerosis (dcSSc) subtype of the disease, and particularly in those who are seropositive to anti RNA polymerase III antibodies [2]. In recent years, the prevalence of SRC has decreased following the initiation of medication therapy with angiotensin-converting-enzyme inhibitors (ACE-i). Previously, SRC mortality rates were as high as 78%. Contemporary studies in the post-ACE-i era suggest lower rates, with mortality rate ranging from 30% to 36% [3]. Nevertheless, progression to end-stage renal disease (ESRD) is evident and may require renal replacement therapies (RRTs). While renal transplant rates in SSc have increased, they constitute a small proportion of SSc-SRC patients (3–8%) and SSc-ESRD patients (4–17%).

In this case report, we elucidated the complex etiology of new-onset ascites through the unusual presentation of a 32-year-old female with abdominal swelling, oliguria, and acute renal failure. This patient's ascites was attributed to urinary bladder rupture, a rare but critical consideration in differential diagnoses. Highlighting the significance of this case, bladder rupture without recent trauma history, especially post-gynecological surgery, poses a diagnostic challenge due to its rarity and potential for severe morbidity and mortality if not promptly recognized and managed. Our patient's journey, from initial symptoms to the eventual discovery of bladder rupture, underscores the necessity of considering this diagnosis in similar clinical scenarios. The case uniquely demonstrates pseudo-renal failure, a phenomenon resulting from reversed dialysis across the peritoneal membrane, which further complicated the diagnostic process.

War is a chaotic situation for most of the public sectors in the countries involved. These sectors also include the medical systems, especially medical education, of which medical communication is often neglected or forgotten due to objective and subjective causes on either side of the involved countries. By planning lessons on various aspects of medicine for countries at war and close mentoring and utilization of modern communications technologies, these difficulties can be minimized without jeopardizing the quality of medical studies nor medical communication. In this perspective article, we describe the objective and subjective measures taken by our team to achieve these goals during the Iron Swords war in our region.

Background: Fetal weight estimation at term is a challenging clinical task.

Objectives: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies.

Methods: We conducted a single-center, retrospective cohort study (2006–2021) of women admitted in the first stage of labor or planned cesarean delivery. Complete blood counts were collected at admission. BW groups were categorized by weight (grams): < 2500 (group A), 2500–3499 (group B), 3500–4000 (group C), and > 4000 (group D). Two study periods were used to evaluate the association between WBC count and neonatal BW.

Results: There were a total of 98,632 deliveries. The dataset analyses showed a lower WBC count that was significantly and linearly associated with a higher BW; P for trend < 0.001 for women in labor. The most significant association was noted for the > 4000-gram newborns; adjusted odds ratio 0.97, 95% confidence interval 0.96–0.98; P < 0.001; adjusted for hemoglobin level, gestational age, and fetal sex. The 2018–2021 dataset analyses revealed WBC as an independent predictor of macrosomia with a significant incremental predictive value (P < 0.0001). The negative predictive value of the WBC count for macrosomia was significantly high, 93.85% for a threshold of WBC < 10.25 × 103/µl.

Conclusions: WBC count should be considered to support the in-labor fetal weight estimation, especially valuable for the macrosomic fetus.

Background: Pelvic organ prolapse in pregnancy is rare. Consequent complications include cervical infection, spontaneous abortion, and premature birth. Conservative management by means of a pessary have been described as improving maternal symptomatology and minimizing gestational risk. The delivery mode is controversial.

Objective: To describe the clinical courses of patients diagnosed with pelvic organ prolapse during pregnancy, and to present our multidisciplinary approach.

Methods: In this retrospective case series, we summarized the obstetrical outcomes of women diagnosed with pelvic organ prolapse during pregnancy in a single university-affiliated hospital.

Results: We identified eight women with advanced uterine prolapse at a mean age of 30.3 years. Seven were diagnosed with advanced uterine prolapse (Pelvic Organ Prolapse Quantification [POPQ] stage ≥ 3). All were treated by pessary placement, which was tolerable and provided symptomatic relief. The pessary type was chosen according to the prolapse stage. In women with cervical prolapse POPQ stage > 2 and cervical edema, a support pessary was less beneficial. However, the prolapse was well-controlled with a space-filling Gellhorn pessary. Low complication rates were associated with vaginal deliveries. The few complications that were reported included minor cervical laceration, postpartum hemorrhage, and retained placenta.

Conclusions: Treatment of pelvic organ prolapse during pregnancy must be individualized and requires a multidisciplinary approach of urogynecologists, obstetricians, dietitians, pelvic floor physiotherapists, and social workers. Conservative management, consisting of insertion of a vaginal pessary when prolapse symptoms appeared, provided adequate support for the pelvic floor, improved symptomatology, and minimized pregnancy complications. Vaginal delivery was feasible for most of the women.

Background: Preeclampsia is a unique vascular disease during pregnancy that generally appears after 20 of weeks gestation or until 6 weeks after delivery. Left undiagnosed, preeclampsia can lead rapidly to death of both mother and fetus.

Objectives: To verify the efficacy of peripheral blood inflammatory markers (BIMs)in diagnosing preeclampsia and compare them with results from other studies.

Methods: Our retrospective case-control study comprised two patient groups. Pregnant women with preeclampsia and pregnant women without preeclampsia were compared for BIMs: neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and mean platelet volume (MPV). The primary endpoint of our research was to assess the predictive power of BIMs for preeclampsia diagnosis.

Results: The sample size was calculated based on expected differences of BIMs between the control and study groups. Comparison of quantitative variables was conducted with independent sample t-test or alternatively by Wilcoxon rank sum test. The MPV values were slightly higher in the preeclampsia group, but not statistically significant. NLR and PLR did differentiate between study and control groups.

Conclusions: The diagnostic accuracy of BIMs is unsatisfactory for preeclampsia diagnosis. Discrepancies concerning these values need to be clarified. Further large prospective studies are necessary to validate the potential factor accuracy in preeclampsia diagnosis.
