Cerebral Syphilitic Gumma Misdiagnosed as a Malignant Brain Tumor.

Syphilitic gumma involvement of the central nervous system is extremely rare and frequently misdiagnosed. The authors report a patient of a cerebral syphilitic gumma resembling a malignant brain tumor in a 62-year-old male. He was first suspected of a malignant brain tumor, but the pathological diagnosis was cerebral syphilitic gumma.

One-step template-free synthesis of monoporous polymer microspheres with uniform sizes via microwave-mediated dispersion polymerization.

One-step facile synthesis of monoporous polymer microspheres via microwave-controlled dispersion polymerization is introduced. This template-free method employing the dispersion polymerization of styrene under microwave irradiation induces directly the formation of uniform monoporous polymer microspheres, with controllable morphologies and sizes, which can be tuned by simply adjusting parameters for the synthesis. A comparison to conventional heating indicates that microwave irradiation plays a vital role in the formation of this novel morphology.

[Clinical efficacy and safety of sublingual immunotherapy using standardized Dermatophagoides farinae extract for children with combined allergic rhinitis and asthma syndrome].

Objective: To study the clinical efficacy of sublingual immunotherapy using standardized Dermatophagoides farinae extract for children with combined allergic rhinitis and asthma syndrome.

Methods: Fifty-two children, from 4 to 14 years of age, with mite-sensitive combined allergic rhinitis and asthma syndrome were treated sublingually with standardized Dermatophagoides farinae extract. The clinical efficacy was evaluated by monthly follow-up visits.
