Pyrimethamine is a folic acid antagonist primarily employed in the treatment of protozoal infections such as toxoplasmosis and malaria. By inhibiting dihydrofolate reductase (DHFR), pyrimethamine disrupts DNA synthesis, effectively impairing the replication of parasitic organisms. Despite its therapeutic efficacy, improper dosing or prolonged use can lead to significant toxicity, particularly involving hematologic and neurologic systems.
Pyridoxine-dependent seizure (PDE) is a rare, autosomal recessive genetic disorder characterized by recurrent seizures that are unresponsive to conventional antiepileptic medications but dramatically responsive to pyridoxine (vitamin B6) supplementation. PDE usually manifests in neonates or infants and, without prompt recognition and treatment, can lead to significant neurodevelopmental impairment. Pathophysiology and Genetic Basis of Pyridoxine-Dependent Seizure
Pyridoxine deficiency, commonly referred to as vitamin B6 deficiency, is a medical condition resulting from insufficient levels of pyridoxine, a vital water-soluble vitamin essential for numerous enzymatic processes. Vitamin B6 is critical for amino acid metabolism, neurotransmitter synthesis, immune function, and hemoglobin production. Its deficiency can lead to a spectrum of clinical manifestations ranging from
Pyoderma gangrenosum is a rare, inflammatory skin disorder characterized by painful, rapidly progressing ulcers with undermined borders and surrounding erythema.

Pustular psoriasis is a rare and severe form of psoriasis characterized by the presence of white, pus-filled blisters (pustules) surrounded by red, inflamed skin. Unlike infections, the pus consists of non-infectious white blood cells. Pustular psoriasis may occur on localized areas, such as the hands and feet, or it can affect the entire body, leading
Pure red cell aplasia (PRCA) is a rare hematologic syndrome characterized by severe normocytic anemia, reticulocytopenia, and selective absence of erythroid precursors in the bone marrow. Chronic lymphocytic leukemia (CLL), a common B-cell lymphoproliferative disorder in adults, is frequently associated with autoimmune complications. Among these, PRCA represents a serious but uncommon manifestation, likely resulting from
Pure red cell aplasia (PRCA) is a rare hematologic disorder characterized by a severe reduction or complete absence of erythroid precursors in the bone marrow, while other hematopoietic lineages remain unaffected. The resulting effect is a profound normocytic, normochromic anemia accompanied by reticulocytopenia, in the absence of leukopenia or thrombocytopenia. PRCA may manifest as either
