Summary
This study highlights atypical subcutaneous paragonimiasis in children. Early diagnosis via epidemiological history, eosinophil counts, and antibody tests, followed by praziquantel treatment, leads to effective outcomes.
Area of Science:
- Parasitology
- Pediatric Infectious Diseases
- Clinical Medicine
Background:
- Paragonimiasis, a parasitic infection, often presents with varied clinical manifestations.
- Subcutaneous nodule-type paragonimiasis is an atypical form, particularly challenging in pediatric cases.
- Accurate diagnosis and effective treatment strategies are crucial for managing this condition.
Purpose of the Study:
- To analyze the clinical characteristics of atypical subcutaneous nodule-type paragonimiasis in children.
- To enhance diagnostic and therapeutic experience for this rare presentation.
Main Methods:
- Retrospective analysis of clinical data from three pediatric cases.
- Review of epidemiological history, peripheral blood eosinophil counts, and Paragonimus antibody test results.
Main Results:
- All patients presented with a clear epidemiological history.
- Significantly elevated peripheral blood eosinophils and positive Paragonimus antibodies were observed.
- Oral praziquantel demonstrated excellent therapeutic effects, with surgery serving as an effective adjuvant treatment.
Conclusions:
- Atypical subcutaneous paragonimiasis in children exhibits complex and non-specific clinical signs.
- Detailed epidemiological history, elevated eosinophils, and positive Paragonimus antibodies are key diagnostic indicators.
- Combined oral praziquantel and adjuvant surgical treatment yield favorable clinical outcomes.

01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
