Background: Sporotrichosis is a subacute or chronic disease caused by a dimorphic fungus, Sporothrix schenckii. The first and most traditional treatment is potassium iodide in satured solution (SSKI) used by DE BEURMANN in 1907. For its effectiveness, it is still used for cutaneous sporotrichosis.
Objective: To evaluate the treatment of cutaneous sporotrichosis with SSKI in relation to clinical cure, side effects, length of treatment and reactivation.
Methods: We conducted a retrospective analysis of medical records over a 24-year period (1981-2005). Patients of all ages who were treated in the hospital´s division of dermatology were included in the study providing that they had a positive culture of S. schenckii. Satured solution of potassium iodide (3 to 6g per day) was the treatment prescribed. For children, half of the dose was prescribed.
Results: The lymphocutaneous disease was prevalent, the cure rate was 94.7%, side effects were described in 5.5% of the cases, mean length of treatment was 3.5 months and possible reactivation was observed in 11.1%.
Conclusion: SSKI is an effective drug, with many side effects, but with low frequency. Resolution was for maximum six months of treatment. SSKI has been found to be a very effective drug in this retrospective study of culture-proven cases of cutaneous and lymphocutaneous sporotrichosis. It should be used as first drug of choice especially in resource-limited settings.

Ionizing radiation emitted from radionuclides is present everywhere in the environment. It is the main source of health hazards to the general public. The present study elaborates on the analysis of primordial radionuclides in the collected soil samples from the Main Central Thrust (MCT) region of Uttarakhand Himalaya in a grid pattern.

Electrolysis of -alkynyl--(formyl)anilides and sodium sulfinates on graphite electrodes delivers biologically sound 3-(sulfonyl)quinol-4-ones with moderate to good yields. The reaction is carried out in an undivided cell in the presence of silver(I) oxide with potassium iodide or sodium tetrafluoroborate as the supporting electrolyte. The reaction tolerates variously substituted anilides as well as aryl and alkyl sulfinates.

In this study, the assessment of the leaves' co-product resulting from the hydrodistillation process was conducted to evaluate its anticorrosive potential for carbon steel in the hydrochloric acid medium. Phytochemical analysis of this biomass revealed its abundance in terms of polyphenols and flavonoids; hence the determination of total polyphenol content recorded a value of 75.4 mg GAE per g extract.

Background: Pregnant women constitute a vulnerable population occasionally affected by zoonotic sporotrichosis. Treatment is challenging due to potentially teratogenic oral medications (itraconazole and saturated potassium iodide solution) or lack of clinical experience during pregnancy (terbinafine). Literature is scarce on sporotrichosis and pregnancy, mainly consisting of case reports.

Tin-based perovskites are more environmentally friendly than their lead-based alternatives. Perovskite light-emitting diodes (PeLEDs) using iodide-based tin perovskites have achieved considerable advancements in efficiency. However, PeLEDs using bromide-based tin perovskites have not progressed as rapidly, primarily due to challenges in controlling their crystallization processes.
