Despite high variability among the studies, synthesis of available data provided significant evidence of beneficial clinical and immunologic effects of probiotics in the treatment of AR, especially with seasonal AR and LP-33 strains. With the rising pool of studies, the most promising strains in specific allergies can be revealed and adjuvant therapy with probiotics can be recommended for the treatment of AR.

Object: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. Methods: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. Results: A detailed guideline about all aspects of allergic rhinitis was created. Conclusion: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

We evaluated the risk of occult contralateral neck involvement according to T stage and ipsilateral neck stage in centrally located supraglottic laryngeal cancer. The side largely involved by the tumor was defined as ipsilateral and the other side was defined as contralateral in terms of the neck dissection side. We retrospectively analyzed clinical and pathologic data from a group of 189 centrally located supraglottic cancer patients in which bilateral neck dissection was part of the primary treatment. Among 378 neck dissection specimens, the rate of bilateral metastasis was 33/189 (17.5%). The rate of occult metastases in the contralateral side were 33/75 (44%) and 6/114 (5.3%), when ipsilateral neck was pN+ and pN-, respectively. Clinically or pathologically positive ipsilateral nodes and the extracapsular spread in the ipsilateral positive nodes displayed significantly higher risk of contralateral metastases. The incidence of occult contralateral metastases did not seem to be affected significantly by T stage of the tumor. Our retrospective study confirmed that the probabilistic criteria of the incidence of contralateral occult metastases in supraglottic laryngeal cancer with tumor largely involving one side and crossing the midline. On the basis of our data, there is a high prevalence of contralateral metastases in tumors with clinically or pathologically positive ipsilateral lymph nodes. The extracapsular spread of the nodes is also an important determinant of the contralateral involvement.
