Emerging data evaluated the possible link between the Coronavirus 19 (COVID-19) vaccine and acute flares of rheumatic autoimmune diseases. However, the association between the COVID-19 vaccine and the development of de-novo rheumatic autoimmune diseases remained unclear. We report the first case series of three male patients who developed new-onset systemic lupus erythematosus following receiving Pfizer BNT162b2 mRNA vaccination. The clinical characteristics share some similarities with drug-induced lupus. More patients with SLE following COVID-19 may be diagnosed in the future. Additional studies will provide more significant insights into the possible immunogenic influence of the COVID-19 vaccine.

Objective: Acute pancreatitis is a serious diagnosis with an increasing incidence in the Western world. In this study we sought to investigate the incidence of idiopathic AP and to compare clinical and prognostic characteristics of idiopathic cases with cases of AP with known etiology. Methods: In this retrospective study of adult hospitalized patients diagnosed with acute pancreatitis between 2012 and 2015, a comparison was made between admissions of patients with known etiology and those for whom no cause was found. Primary outcome was defined as composite outcome of 30-day mortality and complications. Results:Among 560 admissions of 437 patients with a primary diagnosis of acute pancreatitis, the main factors identified were gallstones (51.2%) and idiopathic pancreatitis (35.9%), with alcohol ranked third at only 4.8%. Mortality rate within 30 days of hospitalization was 2.9% and within one year was 7.1%. Use of lipid-lowering, anti-hypertensive, and anti-diabetic medications was more frequent among patients with “idiopathic” disease (70%, 68%, and 33% versus 59%, 56%, and 27%, respectively). Patients admitted with idiopathic AP, in comparison to patients with known AP etiology, had milder disease with shorter hospital stay (3 days versus 4, respectively), and less re-admission in 30 days (7.5% versus 21.2%). Idiopathic AP patients had better prognosis in terms of 30-day death and complication (HR 0.33, 95% CI 0.08–0.40, P<0.001). Conclusion: Idiopathic disease is common among acute pancreatitis patients; the two study groups differed in severity of disease and prognosis. Common use of medications with doubtful value suggests possible under-diagnosis of drug-induced acute idiopathic pancreatitis.
A 64-year-old woman with breast cancer underwent FDG PET/CT for follow-up. The study revealed highly increased FDG uptake in newly diagnosed enlarged axillary lymph nodes, which were worrisome for malignancy. Histopathology revealed a rarely diagnosed benign disease of progressive transformation of germinal centers mimicking malignant lymphadenopathy. As imaging findings of this entity, which usually involves the axillary and cervical areas, have been reported in very few studies, nuclear medicine physicians should be familiar with this potential "false-positive" FDG uptake representing an interpretative pitfall, especially during evaluation of breast cancer patients.
BackgroundElderly patients account for nearly 70% of all primary central nervous system lymphoma (PCNSL) cases. They cannot tolerate aggressive treatment and have poor prognosis with a median overall survival (OS) of less than 2 years and progression‐free survival (PFS) of 6–16 months. Ibrutinib penetrates the blood–brain barrier and has shown activity in PCNSL.MethodsThis prospective study investigated whether ibrutinib maintenance is feasible, and whether it can benefit elderly PCNSL patients in terms of expected 2‐year PFS. It is an open label, phase 2 study in newly diagnosed PCNSL patients 60–85 years old who responded to first‐line high‐dose methotrexate (HDMTX)‐based treatment with partial or complete response. Ibrutinib maintenance (560 mg/d) was continued until disease progression or intolerable toxicity.ResultsTwenty patients were enrolled, with a median age of 72 years (range, 61–80). Median time on ibrutinib maintenance was 12.5 (range, 2–46) months. Twelve patients stopped treatment: five due to central nervous system relapse and seven due to adverse events that were mainly grade 2. Five patients died (25%) all due to relapse. The 1‐ and 2‐year PFS are 90% and 72.6%, respectively, and the 2‐year OS is 89%.ConclusionsThe study reached its primary end points and also showed that ibrutinib maintenance is tolerated reasonably well by the elderly. Therefore, this study supports the concept that ibrutinib maintenance should be further evaluated as an optional consolidation measure in the elderly.
Primary central nervous system lymphoma (PCNSL) is a rare disease with an incidence of 0.4/per 100,000 person‐years. As there is a limited number of prospective randomized trials in PCNSL, large retrospective studies on this rare disease may yield information that might prove useful for the future design of randomized clinical trials. We retrospectively analyzed the data of 222 newly diagnosed PCNSL patients treated in five referral centers in Israel between 2001 and 2020. During this period, combination therapy became the treatment of choice, rituximab has been added to the induction therapy, and consolidation with irradiation was largely laid off and was mostly replaced by high‐dose chemotherapy with or without autologous stem cell transplantation (HDC‐ASCT). Patients older than 60 comprised 67.5% of the study population. First‐line treatment included high‐dose methotrexate (HD‐MTX) in 94% of patients with a median MTX dose of 3.5 g/m2 (range 1.14–6 g/m2) and a median cycle number of 5 (range 1–16). Rituximab was given to 136 patients (61%) and consolidation treatment to 124 patients (58%). Patients treated after 2012 received significantly more treatment with HD‐MTX and rituximab, more consolidation treatments, and autologous stem cell transplantation. The overall response rate was 85% and the complete response (CR)/unconfirmed CR rate was 62.1%. After a median follow‐up of 24 months, the median progression‐free survival (PFS) and overall survival (OS) were 21.9 and 43.5 months respectively with a significant improvement since 2012 (PFS: 12.5 vs. 34.2 p = 0.006 and OS: 19.9 vs. 77.3 p = 0.0003). A multivariate analysis found that the most important factors related to OS were obtaining a CR followed by rituximab treatment and Eastern Cooperative Oncology Group performance status. The observed improvement in outcomes may be due to multiple components such as an intention to treat all patients regardless of age with HD‐MTX‐based combination chemotherapy, treatment in dedicated centers, and more aggressive consolidation with the introduction of HDC‐ASCT.
Background: As point-of-care ultrasound (POCUS) becomes a standard of care procedure, medical schools around the world have started to seek the integration of POCUS courses into their curricula. This puts medical students in a unique position as they are trained in an area in which many physicians lack knowledge. This case series provides a glimpse into the capabilities of POCUS even when used by medical students. Methods: Fourth-year medical students at Ben-Gurion University of the Negev performed numerous POCUS exams during their first clinical rotation at Soroka University Medical Center in Israel. All students completed a course in basic POCUS training and were evaluated in a brief practical exam before entering their first clinical rotation. Four of the cases in which the students took part are presented in this case series. Results: The POCUS exam in the first case discovered pulmonary embolism in addition to the diagnosis of Cushing disease. In the second case, endocarditis could have been diagnosed three days earlier had a POCUS exam been performed. Case 3 demonstrates the additional contribution of POCUS to the decision-making process carried out by physicians and its superiority in quantifying and diagnosing pleural effusion compared to chest X-Ray. Case 4 indicated that POCUS is preferable over chest X-ray and auscultation for the diagnosis of pulmonary edema. Conclusion: This case series may emphasize the capabilities POCUS has when utilized in the standard physical examination and the importance of incorporating POCUS instruction in medical schools for new physicians to acquire this skill.
