Hypothyroidism in Children with Serous Otitis Media
Objective:In this study, we aimed to evaluate the co-existence and prevalence of hypothyroidism in patients with otitis media with effusion (OME) and to determine the possible relationship between OME and hypothyroidism.Methods:The subject group consisted of 46 paediatric patients (26 boys, 20 girls), ranging in age from 4 to 14 years (mean age±SD 7.78±2.86 years), who were treated in the department of otorhinolaryngology for OME; the control group composed of 30 healthy children (20 boys, 10 girls), ranging in age from 3 to 14 years (mean age±SD 7.20±2.86 years). Triiodothyronine (Free T3), thyroxin (free T4), and thyroid-stimulating hormone (TSH) values of 46 children who were treated for OME, in addition to 30 healthy children, were evaluated.Results:Seven patients (15.2%) in the OME group, and one patient (3.3%) in the control group had subclinical hypothyroidism marked only by serum TSH elevations. All of the children in this study, regardless of whether from the subject or control group, had normal serum free T3 and free T4 levels. There was no significant difference between subject and control groups (p>0.05).Conclusion:Although there was no statistically significant difference between subject and control groups in this study, further studies with larger patient groups are needed to investigate the role of hypothyroidism in the aetiology of OME
Omentum adiposity is linked with resistin gene expression
Background: This study demonstrated site-specific adipose tissue resistin gene expression differences in
individuals with and without type 2 diabetes mellitus. The relationship between conventional drug therapy and adipose
tissue resistin gene expression was also determined. Paired omental and subcutaneous adipose tissues were excised
during elective surgery from morbidly obese and obese patients.
Methods: Resistin mRNA expressions were determined by qPCR. All tissue sections also were also analyzed for
their resistin and CD68 protein expressions by immunohistochemistry.
Results: No significant difference for omental and subcutaneous adipose tissue resistin mRNA expression levels
were found among morbidly obese and obese study groups. The omental adipocytes resistin mRNA expressions
increased with macrophage number both in the omental and subcutaneus fat. Resistin mRNA expressions of
the omental and subcutaneous fat were in positive correlation. As the omental adipocytes radius decreased, the
macrophage number increased in subcutaneous fat. In the omentum the adipocytes diameter and areas increased,
in correlation with macrophage number. The antidiabetic drug use was found to increase adipocyte size both in the
omentum and subcutaneous fat.
Conclusions: The higher resistin gene expression in the omental fat may induce the increase in size and number
of adipocytes, thus leading to elavation in omental fat mass
Radiologic findings of screen-detected cancers in an organized population-based screening mammography program in Turkey
PURPOSE:Bahçeşehir Breast Cancer Screening Program is a population based organized screening program in Turkey, where asymptomatic women aged 40–69 years are screened biannually. In this prospective study, we aimed to determine the mammographic findings of screen-detected cancers and discuss the efficacy of breast cancer screening in a developing country.METHODS:A total of 6912 women were screened in three rounds. The radiologic findings were grouped as mass, focal asymmetry, calcification, and architectural distortion. Masses were classified according to shape, border, and density. Calcifications were grouped according to morphology and distribution. Cancers were grouped according to the clinical stage.RESULTS:Seventy cancers were detected with an incidence of 4.8/1000. Two cancers were detected in other centers and three were not visualized mammographically. Mammographic presentations of the remaining 65 cancers were mass (47.7%, n=31), calcification (30.8%, n=20), focal asymmetry (16.9%, n=11), architectural distortion (3.1%, n=2), and skin thickening (1.5%, n=1). The numbers of stage 0, 1, 2, 3, and 4 cancers were 13 (20.0%), 34 (52.3%), 14 (21.5%), 3 (4.6%), and 1 (1.5%), respectively. The numbers of interval and missed cancers were 5 (7.4%) and 7 (10.3%), respectively.CONCLUSION:A high incidence of early breast cancer has been detected. The incidence of missed and interval cancers did not show major differences from western screening trials. We believe that this study will pioneer implementation of efficient population-based mammographic screenings in developing countries
Laryngoscopic Examination During the COVID-19 Pandemic: Turkish Voice Speech and Swallowing Disorders Society and Turkish Professional Voice Society Recommendations
COVID-19 is highly transmissible and spreads rapidly in the population. This increases the occupational risk for health care workers. In otolaryngology clinic practice, patients with upper respiratory tract infection symptoms are common. Also, routine head and neck examinations such as oral cavity examination, nasal/nasopharyngeal examination, or video laryngostroboscopic evaluation are highly risky because of the aerosol formation. To emphasize this issue, two leading otolaryngology organizations in Turkey; 'Voice Speech and Swallowing Disorders Society', and 'Professional Voice Society' gathered a task force. This task force aimed to prepare a consensus report that would provide practical recommendations of the safety measurements during routine clinical care of laryngology patients. To fulfill this, universal aim, on the 2nd and 9th of May 2020, two web-based meetings were conducted by 20 expert physicians. This eighteen items list was prepared as an output

Larengotrakeal rekonstrüksiyonda kosta kıkırdağıyla Dacron greftin karşılaştırması: Deneysel çalışma
Amaç: Larenks rekonstrüksiyonunda Dacron implant kullanımını değerlendirmek ve bu materyalin baş-boyun cerrahilerinde potansiyel endikasyonlarını tartışmak. Yöntem: Her biri 12 Wistar albino sıçandan ibaret üç grup oluşturuldu. Grup 1 kontrol grubu olup bu gruptaki sıçanlarda krikoit kıkırdaktan 5. trakea halkasına kadar 6 mm uzunluğunda kesi yapılarak elde edilen 555 mmlik otolog kosta kıkırdağı transplantasyonu yoluyla anterior larengotrakeal rekonstrüksiyon gerçekleştirildi. Grup 2de, Grup 1de olduğu gibi trakea eşit uzunluklarda bölümlere ayrıldı ve aynı büyüklükte homolog kıkırdak nakliyle anterior larengotrakeal rekonstrüksiyon gerçekleştirildi. Grup 3de trakea, Grup 1e eşit bölümlere ayrıldı ve aynı büyüklükte bir Dacron greftiyle rekonstrüksiyon yapıldı. İmplantasyondan sonraki 12. haftada sıçanlar sakrifiye edildi ve hasta gruplar trakea kesit alanı, parsiyel oksijen basıncı, epitelizasyon, neovaskülarizasyon, enflamatuar hücre infiltrasyonu ve yeni kondrosit oluşumu açısından karşılaştırıldı. Bulgular: Grup 1de postoperatif 2. günde pnömotoraks ve Grup 3de ise 8. günde granülasyon ve krutlanma nedeniyle birer deney hayvanı kaybedildi. Trakea enine kesit alanı ve parsiyel oksijen basıncı açısından gruplar arasında herhangi bir istatistiksel farklılık yoktu. Grup 2 ve Grup 3 arasında epitel gelişimi ve neovaskülarizasyon açısından istatistiksel bir farklılık yoktu ancak Grup 1, diğer iki gruptan anlamlı derecede daha iyi idi. Greft reddinde lenfosit infiltrasyonu önemli bir parametre olup gruplar arasında önemli bir farklılık vardı. Grup 1, diğer 2 gruptan daha iyi olduğu gibi Grup 3ün, Grup 2den hatırı sayılır derecede farklı olduğu belirlendi. Yeni kondrosit gelişimi açısından Grup 1. ile Grup 2 arasında anlamlı bir farklılık vardı. Sonuç: Epitel, neovaskülarizasyon ve kondrosit gelişim skorları daha iyi olduğu için otojen kosta kıkırdağı trakea ve larenks için ideal greft materyalidir. Dacronun kullanıldığı grupta stenoz, enfeksiyon ve rejeksiyon olmadığı, tüm deney hayvanlarında epitel gelişimi ve neovaskülarizasyon tatminkâr derecede oluştuğu için larenks rekonstrüksiyonunda Dacron implantları güvenle kullanılabilmektedir.Objective: To evaluate the use of the Dacron® implant in laryngeal reconstruction and to discuss potential indications of this material in head and neck surgeries. Methods: Three groups consisting of 12 Wistar albino rats in each were formed, Group 1 was the control group and anterior laryngotratecheal reconstruction was performed by transplanting autologous costal cartilage sized 5¥5¥5 mm obtained by 6 mm longitunal sectioning extending from cricoid cartilage to the 5th tracheal ring. Group 2: Trachea sectioning was performed in equal lengths as in Group 1, and anterior laryngotracheal reconstruction was carried out by transplanting the same sized homologous cartilage. Group 3: Trachea sectioning was performed in equal lengths as in Group 1 and anterior laryngotracheal reconstruction was carried out by Dacron® graft in the same size. The rats were sacrificed in the 12th week of the implantation, and the groups were compared in terms of their tracheal section area, partial oxygen pressure, epithelialization, neovascularization, inflammatory cell infiltration and new chondrocyte development. Results: One experimental animal in Group 1 was lost due to pneumothorax on the second day postoperatively. In Group 3, one animal died because of development of granulation and crusting on the 8th day postoperatively. There was no statistically significant difference between the groups in terms of tracheal cross sectional area, and partial oxygen pressure. While there was no significant difference in terms of epithelial development and neovascularization between Groups 2 and 3, while Group 1 was significantly better than Groups 2 and 3. Lymphocytic infiltration is an essential parameter in graft rejection and there was a significant difference between the groups. Group 1 was better than the other two groups but it was determined that Group 3 was considerably different from Group 2. There was a significant difference between Groups 1 and 2 in terms of new chondrocyte development. Conclusion: Autogenous costal cartilage is an ideal graft material for trachea and larynx since scores of epithelial development, neovascularization and chondrocyte development are better. Dacron® implant can be used safely in laryngeal reconstrucion as stenosis, infection and rejection did not occur in Group 3 exposed to Dacron®, and epithelial development and nerovascularization occurred satisfactorily in all experimental animals
