Abstract Background: Cutaneous larva migrans (CLM) is a parasitic infection caused by the accidental penetration of canine hookworm larvae into the superficial layers of human skin. Although typically self-limiting, delayed diagnosis may result in complications such as secondary infections or allergic reactions.
Case Presentation: The case involved a 54-year-old man with a history of hypertension who presented with a creeping, erythematous lesion on his left leg, accompanied by severe pruritus and a history of contact with a pet dog. After confirming the dog’s hookworm infection and conducting further clinical evaluation, a diagnosis of CLM was established. Treatment with albendazole and an antihistamine resulted in complete resolution of the patient’s symptoms.
Conclusion: Although CLM is typically a self-limiting condition, timely initiation of treatment can significantly reduce the duration and severity of symptoms. The growing trend of pet ownership has increased the risk of CLM transmission, underscoring the importance of implementing effective preventive measures.

Abstract Background: Toxoplasmosis, caused by Toxoplasma gondii, is a globally prevalent parasitic infection that often presents with nonspecific symptoms, making diagnosis challenging, especially in immunocompetent individuals.
Case Presentation: We report a case of a 22-year-old immunocompetent male presenting with cervical lymphadenopathy, fever, and flu-like symptoms, initially misdiagnosed as influenza or COVID-19. Despite symptomatic treatment, his condition worsened. Serological testing confirmed acute toxoplasmosis (IgM: 6.64 IU/ml; IgG: 44 IU/ml). Ultrasonography showed hypoechoic cervical lymph nodes, consistent with lymphadenopathy. Treatment with azithromycin, pyrimethamine, and folinic acid for 10 days led to complete symptom resolution.
Conclusion: This case highlights the importance of considering toxoplasmosis in the differential diagnosis of cervical lymphadenopathy, especially in patients with persistent flu-like symptoms. Early serological testing and imaging are crucial for accurate diagnosis and timely intervention. The rapid clinical improvement observed underscores the effectiveness of antiparasitic therapy in immunocompetent individuals. Greater clinician awareness of the diverse presentations of toxoplasmosis is essential to prevent misdiagnosis and optimize patient outcomes.

Abstract Background: Parasitic infections are most prevalent in developing nations and among individuals with weakened immune systems or immunocompromised.
Objectives: Due to the lack of epidemiologic information on such infections, the prevalence of enteric, respiratory, and urogenital parasites was investigated among patients in teaching hospitals in Alborz province, Iran.
Methods: In this cross-sectional study, 1248 samples were collected from January to July 2023. Microscopic examination was performed using direct wet mount, formalin-ether concentration techniques, and trichrome staining. To detect Enterobius vermicularis parasite, we have used the Scotch test method.
Results: The prevalence of parasitic infections was 7.1%. The most commonly identified parasitic infections in the study were Entamoeba histolytica/dispar (29 cases, 2.3%), and Blastocystis sp. (26 cases, 2.1%). 40.2% of our studied cases showed gastrointestinal symptoms and the majority of symptoms were relating to anorexia and abdominal pain.
Conclusion: Given the significant global prevalence of parasitic infections, it is crucial to identify and treat infected individuals, implement urban water improvement programs, avoid the use of human feces as fertilizer in agriculture, and maintain public, and personal hygiene.
