Introduction: Ultraviolet-induced fluorescence dermoscopy (UVF dermoscopy) is a novel diagnostic technique for identifying and diagnosing numerous skin tumors, inflammatory dermatoses, and infectious diseases. The ultraviolet (UV) band has a wavelength ranging from 10 to 400 nm. When intense UV radiation with shorter wavelengths strikes a target chromophore, visible light (VL) with a longer wavelength and lower energy is produced in the skin.

Tuberculosis (TB) triggers a robust immune response, which leads to significant destruction of the lung tissue at the site of infection, aiding in the transmission of (Mtb) to the hosts. The excessive inflammatory response contributes heavily to extracellular matrix (ECM) damage, which is linked to high mortality rates among TB patients. Matrix metalloproteinases (MMPs), particularly MMP-2 and MMP-9, are pivotal in the breakdown of the ECM, worsening tissue destruction.

Central nervous system tuberculosis (CNS-TB) is the most severe extra-pulmonary manifestation of tuberculosis (TB), facing significant challenges due to the limited penetration of anti-TB drugs (ATDs) across the blood-brain barrier (BBB) and their insufficient concentrations at the site of infection. This study aimed to enhance the efficacy of ATDs by encapsulating them in methyl-β-cyclodextrin (M-β-CD) microparticles (ATD-MP) using spray drying, intended for intranasal delivery to manage CNS-TB. M-β-CD microparticles loaded with isoniazid (INH) and rifampicin (RIF) exhibited spherical shapes with slightly deflated surfaces and particle sizes of 6.

The diagnosis of tegumentary leishmaniasis (TL) presents problems by the variable sensitivity and specificity of the tests, and the biological samples used are also invasive. Here, ELISA experiments were performed using paired TL patient urine and serum samples in reaction against the recombinant LiHyS protein, a predicted B cell epitope and parasite antigenic extract (SLA). Two hundred and five paired samples were used, which were provided by TL patients, healthy controls and patients with Chagas disease, leprosy, malaria or HIV-infected.

Accelerating progress requires optimal use of existing tools, advanced diagnostic tests, newer drugs, and vaccines. The search for a vaccine with therapeutic and preventive potential is ongoing, but evidence on effectiveness and safety is lacking.
