Dermatologists use immunotherapy to treat warts

Researchers found that injecting a wart with a skin test antigen from mumps, Candida, or Trichophyton can clear the wart and other distant warts. Patients who responded to treatment were more likely to have an immune response to HPV, suggesting intralesional immunotherapy induces HPV-directed immunity.

Researchers prevent post-traumatic brain damage

Researchers have found that an experimental drug can effectively prevent much of the brain damage caused by traumatic injury. In a study using rat models, the drug was shown to reduce brain damage and improve cognitive and motor function. The breakthrough could potentially lead to new treatments for human traumatic brain injuries.

Study finds maternal exposure to parasitic infection may increase risk of schizophrenia in offspring

A study by Columbia University found a potential link between maternal toxoplasmosis gondii infection and an increased risk of schizophrenia in adult offspring, particularly those with high antibody titers. The researchers suggest that inflammation may be the underlying mechanism behind this association.

Trampoline injuries on the rise

A study found that trampoline injuries among children increased significantly between 1990 and 2002, with 91% of injuries occurring at home. The incidence of severe injuries requiring hospitalization also rose dramatically during this period.

Changes in brain receptors linked to seizures and anxiety during the menstrual cycle

A study published in Nature Neuroscience found changes in GABAA receptors linked to seizures and anxiety during the menstrual cycle. The researchers suggest that these changes may be relevant to post-partum depression and mood swings during pregnancy, and could provide novel therapeutic targets for PMS and catamenial epilepsy.

Mount Sinai study shows Hispanics have worse lung cancer survival rate

A recent Mount Sinai study found that Hispanic patients with stage I non-small cell lung cancer have a significantly lower five-year survival rate of 54% compared to white patients at 62%. This disparity is largely attributed to unequal access to surgical resection, as well as higher rates of advanced-stage diagnosis.
