AbstractObjectiveThe present study evaluated the association between fruit and vegetable intake and the incidence of upper respiratory tract infection (URTI) during pregnancy.DesignIn a cohort of 1034 North American women, each subject was asked retrospectively about their fruit and vegetable intake during the six months before the pregnancy and their occurrences of URTI during the first half of pregnancy. Multivariable-adjusted hazard ratios (HR) were calculated with Cox proportional hazards models.ResultsThe adjusted HR of URTI for women in the highest quartile (median 8·54 servings/d)v. the lowest quartile (median 1·91 servings/d) of total fruit and vegetable intake was 0·74 (95 % CI 0·53, 1·05) for the 5-month follow-up period and 0·61 (95 % CI 0·39, 0·97) for the 3-month follow-up period, respectively. A dose-related reduction of URTI risk according to quartile of intake was found in the 3-month (Pfor trend = 0·03) but not the 5-month follow-up. No association was found between either fruit or vegetable intake alone in relation to the 5-month or the 3-month risk of URTI.ConclusionsWomen who consume more fruits and vegetables have a moderate reduction in risk of URTI during pregnancy, and this benefit appears to be derived from both fruits and vegetables instead of either alone.

Knowledge on the clinical and radiological phenotype of myelin oligodendrocyte glycoprotein (MOG)–related disorders has been growing. We report the case of a patient who presented with subacute onset myelitis after an upper respiratory tract infection with normal cord imaging at onset and follow-up after 4 months (absence of lesions and atrophy), high-titer positive MOG-IgG, and a broad workup excluding other etiologies. The full clinical and radiological spectrum of MOG-related disorders is yet to be completely understood. Testing for MOG-IgG using cell-based assays should be considered in imaging-negative myelitis particularly if initial testing is non-revealing.

Otitis media is mainly caused by upper respiratory tract infection and eustachian tube dysfunction. If external upper respiratory tract infection is not detected early in the middle ear, or an appropriate immune response does not occur, otitis media can become a chronic state or complications may occur. Therefore, given the important role of Toll-like receptors (TLRs) in the early response to external antigens, we surveyed the role of TLRs in otitis media. To summarize the role of TLR in otitis media, we reviewed articles on the expression of TLRs in acute otitis media (AOM), otitis media with effusion (OME), chronic otitis media (COM) with cholesteatoma, and COM without cholesteatoma. Many studies showed that TLRs 1–10 are expressed in AOM, OME, COM with cholesteatoma, and COM without cholesteatoma. TLR expression in the normal middle ear mucosa is absent or weak, but is increased in inflammatory fluid of AOM, effusion of OME, and granulation tissue and cholesteatoma of COM. In addition, TLRs show increased or decreased expression depending on the presence or absence of bacteria, recurrence of disease, tissue type, and repeated surgery. In conclusion, expression of TLRs is associated with otitis media. Inappropriate TLR expression, or delayed or absent induction, are associated with the occurrence, recurrence, chronicization, and complications of otitis media. Therefore, TLRs are very important in otitis media and closely related to its etiology.
