Department of Respiratory Disease, Cukurova University Faculty of Medicine, Yüreğir, Adana 01250, Turkey.
: This study investigates the prevalence of calcification in mediastinal lymph nodes among sarcoidosis patients and the influencing factors. Sarcoidosis is a multisystemic inflammatory disease characterized by non-caseating epithelioid granulomas. Bilateral hilar lymphadenopathy (LAP) is the most common radiographic finding, with studies showing a correlation between the frequency of lymph node calcification and disease duration, with a frequency of 3% relating to a duration of 5 years and a frequency of 20% relating to one of 10 years.

Introduction: STAT3 orchestrates crucial immune responses through its pleiotropic functions as a transcription factor. Patients with germline monoallelic dominant negative or hypermorphic STAT3 variants, who present with immunodeficiency and/or immune dysregulation, have revealed the importance of balanced STAT3 signaling in lymphocyte differentiation and function, and immune homeostasis. Here, we report a novel missense variant of unknown significance in the DNA binding domain of STAT3 in a patient who experienced hypogammaglobulinemia, lymphadenopathy, hepatosplenomegaly, immune thrombocytopenia, eczema and enteropathy over a 35-year period.

Objectives: The aims of this study were to describe the frequency of pleuropulmonary computed tomography (CT) findings in patients with IgG4-related disease (IgG4-RD) and to compare clinical and laboratory characteristics between patients with and without pleuropulmonary involvement in chest CT.
Methods: This is a study conducted within the IgG4-RD study group of the Argentine Society of Rheumatology (GESAR IgG4) cohort of patients with IgG4-RD. Member centers of the group were requested to submit pulmonary CT scans of the patients.
Predictors of severity factors associated with severe scrub typhus among children in a Tertiary Care Hospital.

October 2024
Department of Pediatrics, IMS and SUM Hospital, Siksha 'O' Anusandhan (deemed to be) University, K8, Kalinga Nagar, Bhubaneswar, Odisha, India.
Background Objectives: Scrub typhus is an acute febrile zoonotic disease caused by the obligate intracellular gram-negative bacteria Orientia tsutsugamushi. Growing data over the last few years on the Indian subcontinent suggest that it is one of the most widespread but under-reported diseases. The study aimed to document the clinical and paraclinical profile and evaluate complications of scrub typhus in severe and nonsevere pediatric age groups.
