Role of thoracoscopy in diagnosis of tubercular pleural effusion in low ADA setting- A prospective, observational study.

Background: Tubercular Pleural effusion (TBPE) is one of most common extrapulmonary tuberculosis. It can be difficult to diagnose due to low sensitivity of pleural fluid smear, culture and CBNAAT. Diagnosis of TBPE is then dependent on the level of pleural fluid Adenosine Deaminase (ADA).

A multicentre study to evaluate the diagnostic performance of a novel CAD software, DecXpert, for radiological diagnosis of tuberculosis in the northern Indian population.

Tuberculosis (TB) is the leading cause of mortality among infectious diseases globally. Effectively managing TB requires early identification of individuals with TB disease. Resource-constrained settings often lack skilled professionals for interpreting chest X-rays (CXRs) used in TB diagnosis.

A study on expression of programmed death ligand-1 in small cell lung carcinoma and correlation with clinicopathological parameters.

Small cell lung carcinoma (SCLC) is characterized by rapid growth and an aggressive clinical course. Standard therapy regimes have limited effects on disease course; therefore the prognosis of SCLC is poor. In the current study, the frequency of programmed death ligand 1 (PD-L1) expression in SCLC and its correlation with clinico-pathological features were evaluated.

Panel of serum long non-coding RNAs as potential non-invasive biomarkers for gallbladder carcinoma.

Gallbladder carcinoma (GBC) is a common malignancy and is usually diagnosed in the late stages of the disease. The identification of new effective early diagnostic biomarkers could represent an effective approach in reducing mortality in GBC. Altered expression of long non-coding RNAs (lncRNAs) is believed to be associated with the emergence and development of GBC.

Anorectal balloon cell melanoma: a rare variant.

Balloon cell melanoma is a rare presentation of malignant melanoma, usually on the skin, with less than 100 cases reported. Mucosal BCM is even rarer, with only one case of anorectal BCM reported in English literature. The diagnosis is based on the histopathologic findings of a tumor composed of large, foamy melanocytes, with or without pigmentation, and confirmed by immunohistochemical studies showing expression for melanocytic markers.

Diagnostic Utility of Next-Generation Sequencing in Circulating Free DNA and a Comparison With Matched Tissue in Gallbladder Carcinoma.

Mutation detection for therapy monitoring in cell-free DNA (cfDNA) is used clinically for some malignancies. Gallbladder carcinoma (GBC) presents a diagnostic challenge and has limited late-stage treatment options. To our knowledge, this novel study examines, for the first time, genomic alterations in cfDNA from GBC to assess diagnostic accuracy and therapeutic options.

Programmed Death Ligand-1 Testing in Adenocarcinoma Lung: A Comparative Study of Cell Block versus Biopsy.

Background: Immunotherapy currently stands as a novel treatment option, specifically in cases of advanced non-small cell lung carcinoma (NSCLC). Expression of programmed death ligand-1 (PD-L1) in tumor cells forms the mainstay for the use of anti-PD-L1 monoclonal antibodies in the treatment of NSCLC.

Aims: The objectives of the study were to assess utility of cell blocks for testing of PD-L1 in adenocarcinoma lung and to compare the expression of PD-L1 in cell blocks and the corresponding biopsy specimens.

Toxic potential assessment of hair dye developer 2,4,5,6-tetraaminopyrimidine sulfate exposed under ambient UVB radiation.

Synthetic cosmetics, particularly hair dyes, are becoming increasingly popular among people of all ages and genders. 2,4,5,6-tetraaminopyrimidine sulfate (TAPS) is a key component of oxidative hair dyes and is used as a developer in several hair dyes. TAPS has previously been shown to absorb UVB strongly and degrade in a time-dependent manner, causing phototoxicity in human skin cells.

Involvement of type-1 pathway in phototoxicity of benzo[ghi]perylenean ingredient of tattoo ink at ambient exposure of UVR and sunlight.

Tattooing on different parts of the body is a very common fashion trend in all sections of society globally. Skin allergies and other related skin diseases are very common among tattoo users. Benzo[ghi]perylene (BP) is a PAH and an important component of tattoo ink that showed prominent absorption under ultraviolet radiation (UVR) region.

Benzo(ghi)perylene (BgP) a black tattoo ingredient induced skin toxicity via direct and indirect mode of DNA damage under UVA irradiation.

Tattooing is a very common fashion trend across all the ages and gender of the society worldwide. Although skin inflammatory diseases are very frequent among tattoo users because of the active chemical ingredients used in tattoo ink, yet no ingredient-specific toxicity study has been performed. Benzo(ghi)perylene (BgP) is one of the PAHs and an important ingredient of black tattoo ink that shows strong absorption in UVA and UVB radiation of sunlight.

Next Generation Sequencing in Vitellointestinal Duct Adenoma: Existence of Adenoma-Carcinoma Sequence or too Early to Predict?

Patent vitello-intestinal duct with adenoma is rare presentation. We report a case of a 1-month-old boy presenting with intermittent passage of stool and blood from the umbilicus since birth. On local examination polypoidal mass measuring 1×1 cm was seen protruding from umbilicus with faecal discharge.

Dynamics of cell-free DNA in predicting response in adult diffuse glioma on chemoradiotherapy.

Background: Adult diffuse glioma (ADG) is a heterogeneous primary brain tumor with a variable prognosis and treatment response. Tissue biomarkers and molecular genetic profiling form an integral part of diagnosis and prognostication. However, obtaining tissue in inoperable locations and diagnosis of recurrence can be an issue.

Tattoo inks are toxicological risks to human health: A systematic review of their ingredients, fate inside skin, toxicity due to polycyclic aromatic hydrocarbons, primary aromatic amines, metals, and overview of regulatory frameworks.

Today, tattooing has become very popular among people all over the world. Tattooists, with the help of tiny needles, place tattoo ink inside the skin surface and unintentionally introduce a large number of unknown ingredients. These ingredients include polycyclic aromatic hydrocarbons (PAHs), heavy metals, and primary aromatic amines (PAAs), which are either unintentionally introduced along with the ink or produced inside the skin by different types of processes for example cleavage, metabolism and photodecomposition.

Superoxide anion radical induced phototoxicity of 2,4,5,6-Tetraminopyrimidine sulfate via mitochondrial-mediated apoptosis in human skin keratinocytes at ambient UVR exposure.

2,4,5,6-Tetraaminopyrimidine sulfate (TAPS) is worldwide the most commonly used developer in hair dyes. As skin is the major organ, which is directly exposed to these permanent hair dyes, a comprehensive dermal safety assessment is needed. Hereto, we studied the photosensitization potential and mechanism involved in dermal phototoxicity of TAPS exposed to the dark and UVA/UVB/Sunlight by using different in-chemico and mammalian (HaCaT) cells, as test systems.

Genomic profiling of gallbladder carcinoma: Targetable mutations and pathways involved.

Gallbladder cancer (GBC) carries a poor prognosis and frequently present in late stages of disease. Identification of targetable molecular changes for selecting appropriate treatment and identifying prognostic and therapeutic subsets is required. Next-generation sequencing (NGS) using a frequently mutated for GBC may provide a reference for clinical management.
