Role of cytomorphology in differentiating sarcoidosis and tuberculosis in subjects undergoing endobronchial ultrasound-guided transbronchial needle aspiration.

Conclusion: Sarcoidosis cannot be reliably differentiated from tuberculosis based on cytomorphology alone. A combination of clinical features, endosonography, cytology and microbiology is required for accurate diagnosis. PMID: 32476956 [PubMed - in process]

Discussion “Tattooing of skin via deposition of pigment particles and ink ingredients in the dermis changes normal skin into abnormal skin. Fortunately, this often causes no harm and no disease, although with important exceptions.” Tattoos can be inadvertent from road dirt, gunpowder, pencil graphite etc., but most are desired. Tattoos are common in many cultures and over time..They have been increasing in popularity in the United States over the past few years particularly with a younger, wider and more diverse population. Newsweek reported an 18-country study in 2018 which showed 46% of Americans have a tat...

CONCLUSION: In our Egyptian cohort, more than half the patients had their retinal vasculitis as part of a serious systemic disease, or as part of an infectious process, as tuberculosis. And in view of the significant potential morbidity of these conditions, the local ophthalmologists need to be aware of these entities when faced with patients presenting with retinal vasculitis.

Conclusion: The current accepted criterion for diagnosis of OS may need changes to include such borderline cases due to lack of correlation between clinical and investigative findings. PMID: 30820296 [PubMed]

Abstract Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by the production of ANCAs and systemic necrotizing vasculitis in small vessels. Disordered regulation of neutrophil extracellular traps (NETs) is critically involved in the pathogenesis of AAV. NETs are web-like DNA decorated with antimicrobial proteins; they are extruded from activated neutrophils. The principal degradation factor of NETs in vivo is DNase I; however, NETs resistant to DNase I can persist in tissues and lead to the production of ANCAs. Deposition of NETs has been demonstrated in glomerular crescents ...

Chronic meningitis is a syndrome defined by the presence of clinical signs and symptoms of meningitis or meningoencephalitis with a persisting cerebral spinal fluid (CSF) pleocytosis that are present for at least 4 weeks. The differential diagnosis is broad, with categories including neoplastic, paraneoplastic, autoimmune, and noninfectious inflammatory disorders and central nervous system (CNS) infections. The exact frequency of the different etiologies often varies tremendously across reports; however, among most institutions, common infectious causes of chronic meningitis includeMycobacterium tuberculosis and fungal men...

Sarcoidosis is a systemic, noncaseating, granulomatous disease affecting young adults between the ages of 25 and 40 years, most often of Black origin (35.5/100,000 vs 10.9 in the White population). Although the lower respiratory tract is affected in 90% of cases, ear, nose, and throat locations are very uncommon, with a prevalence varying between 1% and 6.5%.1 In addition, ear, nose, and throat manifestations are nonspecific, and may be difficult to differentiate from other granulomatous diseases such as actinomycosis, aspergillosis, antineutrophil cytoplasmic antibody-associated vasculitis and tuberculosis, thus, frequent...

Authors: Krupa R, Zielonka TM, Hadzik-Blaszczyk M, Wardyn KA, Zycinska K Abstract Fever of unknown origin (FUO) remains one of the most difficult diagnostic challenges. The causes of FUO can be various diseases located in different organs. The aim of the study was to determine the prevalence and nature of pulmonary lesions during FUO. One hundred and sixty one patients with FUO participated in this prospective study. We performed a detailed comprehensive history, physical examination, and a wide spectrum of tests. The most common causes of FUO were infections (39%), autoimmune conditions (28%), and neoplasms (17%)....

Rationale: Palisaded neutrophilic and granulomatous dermatitis (PNGD) is a benign, inflammatory dermatosis with distinct histopathological features often observed in patients with systemic diseases. There were no reports of PNGD without underlying systemic diseases as an underlying cause of hypercalcemia. Herein, we report a case of a 62-year-old man with hypercalcemia due to PNGD, but with no underlying systemic diseases, including tuberculosis, sarcoidosis, or vasculitis. Patient concerns: Laboratory tests showed an elevated C-reactive protein level, an elevated corrected calcium level, a normal 25-hydroxyvitamin D leve...
