Histoplasmosis is an endemic fungal infection caused by the fungus Histoplasma capsulatum. The disseminated form is associated with a high morbidity and mortality in pediatrics. Here we report the case of an immunocompetent female patient diagnosed with disseminated histoplasmosis. She was 3 years old and presented with protracted febrile syndrome and hepatosplenomegaly confirmed by ultrasound. Lab tests showed normocytic anemia and leukopenia. Diagnosis was made by periportal and perisplenic lymph node biopsy. The culture was positive for Histoplasma capsulatum and histopathological studies showed granulomatous lymphadenitis with intracellular yeast-like elements. Amphotericin B was administered at 1 mg/kg/day for 6 weeks, with a favorable clinical course. Disseminated histoplasmosis should be considered in patients from endemic areas who present the triad of fever, hepatosplenomegaly, and cytopenias so as to provide a timely treatment, improve prognosis, and reduce the mortality from this disease.

The abnormal growth of irregular new blood vessels into the subretinal or intraretinal space is known as macular neovascularization (MNV). People over 50 are often affected by this disorder, which is typically brought on by age-related macular degeneration. In addition, MNV can be found in people under 50 years of age, who may present primary ophthalmic diseases such as pathological myopia, angioid streaks, traumatic choroidal rupture, or suspected ocular histoplasmosis syndrome.

Enhancing Solubility of a BCS Class II Drug- Itraconazole by Developing and Optimizing Solid Lipid Nanoparticles using a Central Composite Design.
Pharm Nanotechnol

Department of Pharmaceutical Sciences, Philadelphia College of Pharmacy, Saint Joseph University, Philadelphia, PA.
Background: Itraconazole (ICZ) has been approved by the FDA to treat many fungal infections including, blastomycosis, histoplasmosis, and aspergillosis. ICZ can be also used as prophylaxis in the population who are at high risk for developing systemic fungal infections, such as HIV patients, and chemotherapy patients.
Aim: However, since ICZ is a BCS Class II drug that has low solubility and high permeability, leads to low oral bioavailability.

Background: Access to fungal disease diagnosis is crucial for reducing mortality, yet it varies widely across Argentina, especially outside Buenos Aires. In regions like Santa Fe and Paraná, where most healthcare facilities are under 150 beds, maintaining specialised mycology labs is challenging.
Objectives: This work describes the establishment and first-year results of a centralised Fungal Disease Response Centre (FDRC) and referral network serving this region, covering approximately 1 million inhabitants.
