Objective: The aim of this study is to evaluate relationship between ostiomeatal complex variations (OMC) and maxillary sinus pathologies in children and adolescents using cone-beam computed tomography (CBCT). -/- Methods: CBCT images of 72 patients (44 males and 28 females) aged 7-18 years were evaluated retrospectively. Presence of nasal septal deviation (NSD), nasal septal pneumatization (NSP), concha bullosa (CB), accessory maxillary ostium (AMO), agger nasi cell (ANC), Haller cell (HC), Onodi cell (OC), ethmoid sinusitis and maxillary sinus pathologies were investigated. (...) Maxillary sinus pathologies were classified. Correlations of OMC variations with each other, maxillary sinus pathologies and ethmoid sinusitis were investigated. Chi-square test was used to analyze relationships among variables and distribution of parameters. -/- Results: NSD was determined in 70.8%, NSP in 40.3%, ethmoid sinusitis in 75%, maxillary sinus pathology in 34.8% of images. OMC variations rates were detected as CB 31.3%, AMO 16%, ANC 16%, HC 24.3% and OC 18.8%. The most common maxillary sinus pathology was localized mucosal thickening, with a rate of 15.3% on right and 22.2% on left. Statistically significant differences were determined between almost all OMC variations with each other, and between anatomical variations in OMC with maxillary sinus pathologies except for NSP and AMO (p < 0.05). The presence of ethmoid sinusitis was more common in males (p =0.026). -/- Conclusion: Anatomical variations in OMC had no significant effect on maxillary sinus pathology except for NSP and AMO. Besides, most of anatomical variations in OMC were statistically significantly correlated with each other. CBCT visualization of these variations is important for sinonasal surgery and is an effective method in children and adolescents with low radiation dose and high image quality compared to computed tomography.

Objective: Inflammation is one of several etiopathological mechanisms contributing to bipolar disorder. Neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) are relatively cheap hematological parameters recommended to measure the level of inflammation. In this study, the NLR, MLR, and PLR values of the same patients during manic and euthymic periods were compared to a healthy control group. -/- Methods: This retrospective study was conducted on inpatients with bipolar disorder manic episodes at the University Faculty of Medicine psychiatry clinic. (...) Ninety-nine patients with manic episodes of bipolar disorder and age and gender-matched 101 volunteers without prior psychiatric illness were included in the study. Neutrophil, lymphocyte, monocyte, and platelet counts during the disease period were recorded, and NLR, MLR, and PLR values were calculated from these values. Similar hematological parameters of the same patients in the euthymic period after discharge were compared. -/- Results: Patients with manic episodes were shown to have significantly higher neutrophil, platelet, NLR, MLR, and PLR levels than the control group (p<0.001). Monocyte count was significantly lower in manic episode patients compared to controls (p<0.001). Neutrophil and monocyte counts were significantly lower during the euthymic period compared to the control group, while NLR, MLR, and PLR levels were higher (p<0.001). -/- Conclusions: The fact that NLR, MLR, and PLR are higher in BD patients compared to the healthy control group in both manic and euthymic periods indicates that they can be used as trait biomarkers.

Felsefe Optiğinden Aşkın Renkleri kitabı Senail Özkan’ın bir takdim yazısı, giriş ve yedi bölümden oluşmaktadır. Kitapta kaynakçaya yer verilmemiştir. Halilov, kitabın giriş kısmında ‘aşk’ın ne olduğunu ve hangi ilim dalı tarafından ele alınması gerektiğini açıklamıştır. Ona göre aşk insanın manevi âleminin en derin katmanlarında ortaya çıktığı için temel itibariyle bilinçdışı alana aittir. İlim onu irdeleyemez, aşk, ilim için muğlak bir alandır ve mantıki düzlemde değerlendirilmesi oldukça zordur. İlim açısından incelenemediği için bu işi felsefe ve şiir üstlenmektedir.(s.16, s. 55) Şiir ve (...) aşk ilişkisine değinen Halilov, şiirin aşk ile büyük bir ilgisi olduğunu Doğu’da ve Batı’da aşk konusunun şiir sanatının kapsamı içinde değerlendirildiğini söyler. Doğu’da Nizami, İbn Arabi, Mevlana, Fuzuli, İkbal ve Cavid’e kadar Doğu şairlerinin aşk konusunu ele aldığı ve bununla ilgili eserler verdiğini ekler. Halilov’a göre Doğu’da aşk, ‘ilahi nitelikte’ ele alınmaktadır. Bütün kitap boyunca ‘ilahi aşk’ meselesi üzerinde duran Halilov bazen bu görüşü savunmuş bazen de tutarsız ve gerçek hayattan uzak olduğunu anlatmaya çalışmıştır. Ona göre aşk, ilahi olmaktan ziyade ferdi, bireysel veya insanidir. Aşk, ‘yerle gök arasında’ olması gerekmektedir. Bu açıdan Halilov aşkı, rasyonel bir düzlemde alan Batı öğretisini tercih ettiğini söylemektedir.(s.18) Fakat kitabına baktığımızda aslında Halilov’un bazı gerekçeler nedeniyle bu konuda biraz tereddütte kaldığını göreceğiz. (s.25). (shrink)
