Toxoplasma gondii infection in patients with lung diseases in Shandong province, eastern China.

Toxoplasma gondii, an intracellular protozoan parasite, can induce various clinical symptoms. T. gondii has been considered to play an important role in the pathogenesis of lung diseases. This survey was conducted to explore the correlation between T. gondii infection and lung diseases through a case-control study carried out in Shandong province, eastern China. In the present survey, T. gondii IgG antibodies were found in 76/398 (19.10%) of patients with lung diseases, which was significantly higher (P < 0.001) than the level found in the control subjects (35/398; 8.79%) through serological diagnosis. Patients with lung cancer have the highest T. gondii seroprevalence (26.19%), followed by Pulmonary cyst (25.00%), Tuberculosis (17.07%), Pneumonia (16.33%) and chronic obstructive pulmonary disease (COPD) (16.05%). Moreover, a semi-nest PCR targeted T. gondii B1 gene was employed to detect the T. gondii DNA in the blood samples. T. gondii DNA was detected in 5.53% blood samples of patients with lung diseases and 2.51% control subjects, respectively. The present study firstly shows that T. gondii has a high probability to infect the patients with lung diseases. Thus, the potential presence of T. gondii in patients with lung diseases should be appreciated during in the course of treatment and safeguard procedures should be implemented to protect vulnerable patients with lung diseases.

Intracranial Mirror Aneurysm: Epidemiology, Rupture Risk, New Imaging, Controversies, and Treatment Strategies.

There are some controversies about the surgical treatment strategy of mirror aneurysms. Whether to choose 1-stage or 2-stage surgery, bilateral or unilateral craniotomy, or surgical or interventional treatment are the main points in dispute. In this review, the different surgery strategies faced by patients are discussed. Different surgical methods are adopted based on the patient's individual state and the location and size of the aneurysm. A new imaging method is introduced using 3D Slicer, which clearly recognizes the relationship among aneurysm, brain tissue, skull, and nerve. The 3D Slicer can help surgeons undertake adequate preoperative preparation. In addition, we also introduce some ruptured factors (e.g., age, gender, hypertension, morphologic, and hemodynamic) concerning mirror aneurysm. Systematic discussion of the controversies and methods in surgical treatment of mirror aneurysms may provide new perspectives in future research for the prevention and treatment of mirror aneurysms.
