Background: Selective delivery of anticancer agents to target areas in the body is desirable to minimize the side effects while maximizing the therapeutic efficacy. Anthracycline antibiotics such as doxorubicin (DOX) are widely used for treatment of a wide variety of solid tumors.This study evaluated the potential of a polymeric micellar formulation of doxorubicin as a nanocarrier system for targeted therapy of a folate-receptor positive human ovarian cancer cell in line.
Results: DOX-conjugated targeting and non-targeting micelles prepared by the dialysis method were about 188 and 182 nm in diameter, respectively and their critical micelle concentration was 9.55 μg/ml. The DOX-conjugated micelles exhibited a potent cytotoxicity against SKOV3 human ovarian cancer cells. Moreover, the targeting micelles showed higher cytotoxicity than that of non-targeting ones (IC₅₀= 4.65 μg/ml vs 13.51 μg/ml).
Conclusion: The prepared micelle is expected to increase the efficacy of DOX against cancer cells and reduce its side effects.

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is currently used in the therapy of several solid malignancies. This agent has been associated with several dermatological side-effects, the most common being papulo-pustular acneiform rash. Herein we describe a unique skin effect in a patient treated with erlotinib for non-small cell lung cancer.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

Juvenile dermatomyositis with emphasized vasculopathy is rare, but the most severe form of the disease, with a poor prognosis with relapsing and chronic course or, in some cases, lethal outcome. We present a case of a 19-year-old Caucasian female, who developed severe acute juvenile dermatomyositis with emphasized multisystem vasculopathy, including retinal vasculopathy and maculopathy (cotton-wool spots, retinal hemorrhages, macular edema) at the age of 8. Due to no response to standard treatment protocols and rapid worsening of clinical symptoms and laboratory findings, a TNF inhibitor (infliximab) was introduced after the third week of treatment resulting in complete normalisation of muscle enzyme levels and complete resolution of eye changes within the next 2 weeks with a gradual general recovery.

IgE acts primarily via the high affinity IgE receptor (FcεRI) and is central to immediate hypersensitivity reactions (anaphylaxis). However, IgE is also important in the development of chronic hypersensitivity reactions (allergy). In the cardiovascular system, numerous clinical studies have investigated serum IgE levels, mainly in the context of myocardial infarction, and have established a clear association between IgE and ischemic cardiac events.

Background: Amiodarone, a common antiarrhythmic drug, is known for its severe side effects, including pulmonary toxicity, which involves oxidative stress and apoptosis. Artemisinin, an antimalarial drug, has shown cytoprotective properties by inhibiting oxidative stress and apoptosis. This study investigated the protective effects of artemisinin against amiodarone-induced toxicity in human bronchial epithelial cells (BEAS-2B) and mouse models.
