Cranberry juice has been shown to reduce urine infections in women with frequent recurrences. I recommend mixing 100 percent cranberry juice with seltzer water to avoid the added sugar of most cranberry juice cocktails. Healthy bacteria, such as in live yogurt or probiotics, also can reduce recurrences. I have had a handful of cases in which I have needed to use prophylactic antibiotics, but neither the patients nor I were really happy with that solution, although it is effective.
Gynecologists, urologists, urogynecologists and infectious disease specialists may all be expert in helping prevent recurrent UTI.
DEAR DR. ROACH: My younger sister was pregnant when we took a flight. When the plane stopped in Brazil, the cabin was sprayed with an aerosol that caused the cabin to remain milky white for two to three hours.
Her newborn was born one month premature and was diagnosed with achondroplasia, a form of dwarfism. Do you know of any studies linking achondroplasia with chemical exposure during the first trimester of pregnancy? — M.T.
ANSWER: The spray probably was an insecticide. The U.S. stopped spraying cabins after the Centers for Disease Control and Prevention found the practice ineffective and potentially harmful. Spraying the cabin is humiliating and creates an entirely reasonable fear.
Achondroplasia is caused by a specific gene abnormality. It can be inherited, but also occurs as a spontaneous change in the DNA (mutation). It is estimated that every person has several spontaneous mutations. In your sister’s case, the mutation would likely have happened before your sister was born. For this specific case, I believe the spray did not cause the achondroplasia.
