IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition. Accumulated research and data since 2003 have increasingly affirmed its classification as a systemic disease. Although IgG4-RD generally presents with involvement of one or several organ systems, it can affect almost any organ. The disease manifests gradually with the development of tumor-like lesions.

Constitutional symptoms, such as systemic fever and elevated inflammatory markers, are generally absent in association with this pathological condition. However, it is common for patients to exhibit allergy characteristics in addition to a slight increase in peripheral blood eosinophilia. The clinical manifestations of the disease exhibit variability on the specific organ system affected. Specific involvement of organs can ultimately result in organ failure. For example, retroperitoneal fibrosis commonly leads to post-renal failure [1]. The 2020 Revised Comprehensive Diagnostic (RCD) criteria for IgG4-RD include three components for diagnosis: clinical and radiological components (1), serological diagnosis (2), and unique pathological diagnosis (3). When all three are present it is a definitive diagnosis. The presence of components 1 + 3 constitutes a probable diagnosis, while the presence of components 1 + 2 indicates possible diagnosis [2].

Testicular involvement of IgG4-RD has been described in a few case reports. However, the uniqueness of our case is the manifestation of a testicular mass as a different target organ of relapse in a patient in remission from retroperitoneal fibrosis.

Background: Erythema nodosum (EN) is the most common type of panniculitis, commonly secondary to infectious diseases.

Objectives: To elucidate the causative factors and the clinical presentation of patients with EN (2004–2014) and to compare their data to those reported in a previous study.

Methods: A retrospective study was conducted of all patients diagnosed with EN who were hospitalized at Soroka University Medical Center (2004–2014). The clinical, demographic, and laboratory characteristics of the patients were compared to those in a cohort of patients diagnosed with EN from 1973–1982.

Results: The study comprised 45 patients with a diagnosis of EN. The most common symptoms of patients hospitalized with EN were arthritis or arthralgia (27% of patients). Patients with EN, compared to those reported in 1987, has significantly lower rates of fever (18% vs. 62% P < 0.001), streptococcal infection (16% vs. 44%, P = 0.003), and joint involvement (27% vs. 66%, P < 0.001). In addition, fewer patients had idiopathic causes of EN (9% vs. 32%, P = 0.006).

Conclusions: In the past decades, clinical, epidemiological, and etiological changes have occurred in EN patients. The lowering in rate of fever, streptococcal infection, and joint involvement in patients with EN are probably explained by improvements in socioeconomic conditions. The significantly decreasing rate of idiopathic causes of EN is possibly due to the greater diagnostic accuracy of modern medicine. The results of the present study demonstrate the impact of improvements in socioeconomic conditions and access to healthcare on disease presentation.

Background: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy.

Objectives: To highlight the diagnostic and therapeutic steps in pediatric IDH[1].

Methods: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed.

Results: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9–20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications.

Conclusions: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.
