Background: Ocular trauma in the pediatric population may lead to cataract formation. Managing traumatic cataracts in a visually immature child is a major challenge and can result in poor visual outcome.

Objectives: To review our long-term surgical experience with childhood unilateral traumatic cataracts.

Methods: A retrospective observational study of children with unilateral traumatic cataracts with minimal follow-up of 5 years was conducted. Main outcomes included final visual acuity (VA) and occurrence of complications.

Results: Of the 18 children included in the study, 83% were male. Mean follow-up time was 12.5 years. Median age at injury was 7.5 years. Eleven patients (61%) presented with penetrating trauma injuries and 7 (39%) with blunt trauma. Sixteen patients (89%) had cataracts at presentation, while in two the cataracts developed during follow-up. Of the 18 total, cataract removal surgery was conducted in 16 (89%) with intraocular lens (IOL) implantation in 14 (87.5%), while 2 remained aphakic (12.5%). Two (11%) were treated conservatively. Long-term complications included IOL dislocation in 5 (36%), glaucoma in 8 (44%), and posterior capsular opacity in 10 (71%). No correlation was found between final visual acuity and the time interval between injury and IOL implantation nor between final VA and age at trauma. However, the final VA did correlate with time of follow-up.

Conclusions: Severe complications occurred in over 30% of the patients during a long follow-up (mean 12.5 years). This finding shows the importance of discussions between the operating physician and the parents regarding the prognosis and necessity of scheduled follow-up.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, which is caused by chronic obstruction of major pulmonary arteries. CTEPH can be cured by pulmonary endarterectomy (PEA). PEA for CTEPH is a challenging procedure, and patient selection and the perioperative management are complex, requiring significant experience.

Objectives: To describe the establishment of a national CTEPH–PEA center in Israel and present results of surgery.

Methods: In this study, we reviewed the outcomes of PEA in a national referral, multi-disciplinary center for CTEPH–PEA. The center was established by collaborating with a high-volume center in Europe. A multidisciplinary team from our hospital (pulmonary hypertension specialist, cardiac surgeon, cardiac anesthesiologist and cardiac surgery intensivist was trained under the guidance of an experienced team from the European center.

Results: A total of 38 PEA procedures were performed between 2008 and 2018. We included 28 cases in this analysis for which long-term follow-up data were available. There were two hospital deaths (7%). At follow-up, median New York Heart Association (NYHA) class improved from III to I (P < 0.0001), median systolic pulmonary pressure decreased from 64 mmHg to 26 mmHg (P < 0.0001), and significant improvements were seen in right ventricular function and exercise capacity.

Conclusions: A national center for performance of a rare and complex surgical procedure can be successfully established by collaboration with a high-volume center and by training a dedicated multidisciplinary team.

Background: Implant-related spinal infections are a surgical complication associated with high morbidity. Due to infection, hardware removal may be necessary, which could lead to pseudarthrosis and the loss of stability and alignment.

Objectives: To evaluate the accuracy and diagnostic value of ¹⁸F-fluorodeoxyglucose positron-emission tomography/computed tomography (¹⁸F-FDG PET/CT) in the workup of patients with suspected implant-related infections of the spine and to assess the clinical impact of PET/CT results on the management of these infections.

Methods: The study included nine consecutive patients with a history of spinal surgery who underwent PET/CT for evaluation of suspected spinal implant related infection. All imaging studies were performed between January 2011 and December 2013. All ¹⁸F-FDG PET/CT scans were performed on an 8 slice PET/CT following an ¹⁸F-FDG injection. Images were scored both visually and semi-quantitatively by a radiology expert. Results were compared to additional imaging studies when available, which were correlated to clinical and bacteriological findings allowing calculation of sensitivity, specificity and accuracy.

Results: Among the patients, five experienced hardware-related spinal infection. ¹⁸F-FDG PET/CT sensitivity was 80%, specificity 100%, and accuracy 88.9%. One scan produced a false negative; however, a second PET/CT scan revealed an infection.

Conclusions: PET/CT was found to be valuable for the diagnosis of postoperative hardware-related spinal infection, especially when other imaging modalities were uninformative or inconclusive. As such, PET/CT could be useful for management of infection treatment.

Background: Although cross-reactions between Epstein-Barr virus (EBV) and human systemic lupus erythematosus (SLE) autoantigens occur, a complete analysis of the potential EBV peptide cross-reactome has not been performed.

Objectives: To analyze the whole EBV proteome searching for peptides common to SLE-related proteins and endowed with an immunological potential.

Methods: Fifty-one SLE-related proteins were analyzed for hexapeptide sharing with EBV proteome using publicly available databases.

Results: An extremely high number of hexapeptides are shared between 34 human SLE autoantigens and EBV proteins. The peptide sharing mostly occurs with complement components C4 and Interleukin-10 (IL-10).

Conclusion: This study thoroughly describes the EBV vs. SLE autoantigens peptide overlap and powerfully supports cross-reactivity as a major mechanism in EBV-associated SLE etiopathogenesis.

Background: Fibromyalgia is a syndrome of unknown etiology that is characterized by widespread pain, which severely impairs quality of life. Several forms of occupational and alternative therapy have demonstrated beneficial effects in fibromyalgia patients.

Objective: To assess the effects of participation in a floral design course on physical and psychiatric symptoms in a cohort of fibromyalgia patients.

Methods: This study was conducted as an observational study. Women diagnosed with fibromyalgia over the age of 18 were recruited to participate in one of two 12-week flower design (floristry) courses. Demographic details, disease activity indices, and anxiety and depression scores were calculated for all participants at baseline, week 12, and study completion. Physical and mental health of the two groups were compared throughout the study time-points.

Results: The study was completed by 61 female fibromyalgia patients who were included in the final analyses; 31 patients participated in the first floristry course and 30 in the second. Significant improvements in the 36-Item Short Form Survey physical and mental health components, visual analog scale, Fibromyalgia Impact Questionnaire, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale scores for the entire study population and for each group separately could be seen following participation in each floristry course.

Conclusions: Participation in a floristry course may lead to a significant improvement in pain and psychiatric symptoms in fibromyalgia patients. These findings highlight the potential benefit of utilizing occupational therapy programs, such as a floristry course, for improving quality of life in fibromyalgia.

Rheumatic diseases commonly affect women of childbearing age, when women may be contemplating pregnancy or they discover an unplanned pregnancy. Therefore, specific issues about pregnancy planning and management are commonly encountered in patients during these times. Knowledge of the effect of pregnancy on disease activity is important for counseling. This review summarizes recent data on the course of different rheumatic diseases during pregnancy and the postpartum period. Rheumatoid arthritis and systemic lupus erythematosus are the most commonly investigated diseases. Data are increasing about spondyloarthritis. Sparse data are available for other rheumatic diseases. Despite the differences in these diseases and the various courses these disease take during pregnancy, a common feature is that active maternal disease in the months prior to conception increases the risk of flares during pregnancy, which in turn can lead to adverse pregnancy outcomes. Therefore, maternal and fetal health can be optimized if conception is planned when disease is inactive so that a treatment regimen can be maintained throughout pregnancy.

Uveitis is an inflammatory disorder of the uveal tract of the eye that can affect both adults and children. Non-infectious uveitis can be an expression of a systemic autoimmune condition, or it can be idiopathic. It is a serious disease, associated with possible severe complications leading to visual impairment and blindness. For this reason, a prompt diagnosis and assessment of an appropriate treatment, with the collaboration of specialists such as ophthalmologists and rheumatologists, are extremely important. Many treatment options may be associated to side effects; therefore, clinicians should follow a stepladder approach starting with the least aggressive treatments to induce remission of inflammation. In this review, we reported the current evidence-based treatments for non-infectious uveitis in pediatric and adult patients with particular attention to the biologic response modifier treatment options. Important multicenter studies have demonstrated the efficacy of adalimumab, both in adults (VISUAL I, VISUAL II, VISUAL III) and in children (SYCAMORE, ADJUVITE), while for other agents data are still scarce.

Recurrent pericarditis is a state of repetitive inflammation of the pericardium with intervals of remission. The etiology of recurrent pericarditis is still largely unknown, yet most causes are presumed to be immune mediated. Genetic factors, including human leukocyte antigen (HLA) haplotypes, can be involved in dysregulation of the immune system and as a predisposition to several autoimmune conditions, including recurrent pericarditis. Several diseases are frequently associated with such manifestations. They include systemic lupus erythematosus, familial Mediterranean fever, and tumor necrosis factor receptor-associated periodic syndrome. However, idiopathic recurrent pericarditis remains the most frequently observed clinical condition and the conundrum of this disease still needs to be solved.

Background: Benign rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS) is a common childhood epileptic syndrome. The syndrome resolves in adolescence, but 1–7% of patients have an atypical presentation, some of which require aggressive medical treatment. Early treatment may prevent complications and neurocognitive deterioration. Variants include Landau-Kleffner syndrome (LKS) and electrical status epilepticus during sleep (ESES).

Objectives: To determine data driven identification of risk factors and characterization of new subtypes of BCECTS based on anontology. To use data mining analysis and correlation between the identified groups and known clinical variants.

Methods: We conducted a retrospective cohort study comprised of 104 patients with a diagnosis of BCECTS and a minimum of 2 years of follow-up, between the years 2005 and 2017. The medical records were obtained from the epilepsy service unit of the pediatric neurology department at Dana–Dwek Hospital, Tel Aviv Sourasky Medical Center. We developed a BCECTS ontology and performed data preprocessing and analysis using the R Project for Statistical Computing (https://www.r-project.org/) and machine learning tools to identify risk factors and characterize subgroups.

Results: The ontology created a uniform and understandable infrastructure for research. With the ontology, a more precise characterization of clinical symptoms and EEG activity of BCECTS was possible. Risk factors for the development of severe atypical presentations were identified: electroencephalography (EEG) with spike wave (P < 0.05), EEG without evidence of left lateralization (P < 0.05), and EEG localization (centrotemporal, frontal, or frontotemporal) (P < 0.01).

Conclusions: Future use of the ontology infrastructure for expanding characterization for multicenter studies as well as future studies of the disease are needed. Identifying subgroups and adapting them to known clinical variants will enable identification of risk factors, improve prediction of disease progression, and facilitate adaptation of more accurate therapy. Early identification and frequent follow-up may have a significant impact on the prognosis of the atypical variants.

Background: Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives: To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods: A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results: We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.

Erectile dysfunction (ED) is a syndrome associated with endothelial dysfunction, which may predict cardiovascular events in men presenting with this syndrome. It has been shown to be associated with a higher rate of acute myocardial infarction and cardiovascular mortality, vascular inflammation, and impaired endothelial function. In this review we present the literature findings and describe the mechanistic pathways that are known to be involved in this syndrome and its related clinical consequences.
