Diploe thickness and cranial dimensions in males and females in mid-Anatolian population: an MRI study.

BACKGROUND The objective of this study is the classification of the thickness of diploe and dimensions of cranium at different points of cranium in men and women according to age groups. MATERIAL AND METHOD In the radiology archive, measurements were made at different points in magnetic resonance (MR) images of 305 (188 females and 117 males) patients, the average ages of whom were 40.98±20.44 (age range: 4-90) and who had no disorder of the bones. To determine diploe thickness, midfrontal, back and front bregma, lambda, opisthocranion and euryon points were used in the measurement. As for the determination of cranial volume, distances between glabella-opisthocranion, basion-vertex, basion-opisthion, euryon-euryon, nasion-basion, nasion-bregma, bregma-lambda and lambda-opisthocranion were measured. The data were loaded to Statistical Package for the Social Sciences (SPSS) 16.0 program. T-test, Mann-Whitney U, Pearson correlation coefficient and Kruskal-Wallis variance analysis were used in the statistical assessment. Results with a p value smaller than 0.05 were accepted as significant. RESULTS There was a statistically significant positive correlation between age and diploe thickness in all measurement points. The diploe thickness was also increased with age (p<0.05). In all points, average diploe thickness was higher in age 61 and over than the other groups (p<0.001). At the same time, diploe thickness in parietal bones was lower than frontal and occipital bones in both sexes. According to craniometric results cranium in males was bigger (p<0.001). While the distance between glabella-opisthocranion increased in both sexes aged 61 and over, basion-vertex height decreased in women in the same group (p<0.05). Interestingly, there was no meaningful statistical difference among age groups in terms of maximum cranial width (p>0.05). Foramen magnum length decreased related to age in both men and women (p<0.001). CONCLUSION These results related to diploe thickness and cranium dimension may be leading in the determination of sex and age; surgical interventions to the cranium and bone graft choice may increase the reliability of the operation.

Incidental diagnosis of abnormalities of nasal structures, paranasal sinuses, and mastoid cells on MRI of the head in adult patients with chronic headache

Abstract Aim. The purpose of this study to evaluate retrospectively the incidental abnormalities of nasal structures, paranasal sinuses, and mastoid cells on MRI of the head in adult patients with chronic headache. Methods. We collected the presence of abnormalities of nasal structures, paranasal sinuses, and mastoid cells, diagnosed incidentally, from the existing MRI reports by qualified radiologists in a population of 3200 adult patients examined for the differential diagnosis of chronic headache. Results. There were no significant differences among the study groups with regard to the rates of types of chronic sinusitis, mastoiditis, nasal structural abnormalities, and multiple sinusitis (p>0.05). The rates of nasal septum deviation were significantly higher in patients with chronic maxillary and ethmoid sinusitis (p 0.05). Nazal septum deviasyonunun orani, kronik maksiller ve etmoid sinuzitli hastalarda anlamli olarak yuksek saptandi (p<0.05). Kronik maksiller sinuzitli hastalarda retansiyon kist orani anlamli olarak yuksek saptandi (p<0.05). Sonuc. MRG yapilmasi, kronik paranazal sinuzit ve mastoidit’e ek olarak yetiskin hastalarda sinuzit ve mastoidit ile iliskili olabilecek dogumsal ve sonradan kazanilan kronik inflamatuvar degisiklikleri gosterir. MRG ile, klinik olarak saptanmasi zor, kronik bas agrisi olan yetiskinlerde kulak bogaz burun ve beyin yapilari icin onemli bilgiler saglayabilir. Anahtar sozcukler: nazal yapilar, paranazal sinusler, mastoid hucreler, manyetik rezonans goruntuleme, kronik bas agrisi

Fallot Pentalojisi’nin eşlik ettiği Dandy-Walker varyasyonu: Olgu sunumu

Ozet Dandy-Walker varyasyonu, 4. ventrikul ve sisterna magna arasindaki devamlilikla sonuclanan vermisin parsiyel agenezisi ile karakterize santral sinir sisteminin nadir bir anomalisidir. Literaturde ilk kez 1988’de Kohyama ve arkadaslari tarafindan bildirilen Dandy-Walker varyasyonu ve Fallot Tetralojisi birlikteligi daha sonraki yillarda birkac vaka sunumu seklinde bildirilmistir. Biz bu yazida, Dandy-Walker varyasyonu ve Fallot Pentalojisi olan 2 gunluk bir erkek hastayi bildiriyoruz. Anahtar sozcukler: Dandy-Walker varyasyonu, Fallot Pentalojisi Abstract Dandy-Walker variant is a rare anomaly of the central nervous system that is characterized by partial agenesis of vermis and results in persistence of the 4. ventricule and cisterna magna. Firstly, in 1988 Kohyama et al. reported the coexistence of Dandy-Walker variant and tetralogy of Fallot. Afterwards, it is reported as several case reports in the literature. In this case report, we report a 2 days-old male patient with Dandy-Walker variant and pentalogy of Fallot. Keywords: Dandy-Walker variant, pentalogy of Fallot

Kronik obstrüktif akciğer hastalığında orbital kan akım değişikliklerinin renkli doppler ultrasonografi ile değerlendirilmesi

Ozet Amac . Kronik obstruktif akciger hastaligi (KOAH) olgularinin okuler kan akim hizlarini olcup okuler hemodinaminin etkilenip etkilenmedigini saptamaktir. Yontem. 2009-2010 yillari arasinda Global Initiative for Chronic Obstructive Lung Disease (GOLD) kriterlerine gore degerlendirilerek 20’er kisilik 4 gruba ayrilan KOAH tanili 80 hasta ve rastgele secilen 63 saglikli birey olmak uzere toplam 143 olgunun Renkli doppler ultrasonografi (RDUS) teknigi ile santral retinal arter (SRA) ve oftalmik arter (OA) pik sistolik hizlari (PSH), end diastolik hizlari (EDH), rezistif indeksleri (RI) ve santral retinal ven (SRV) akim hizlari olculdu. Bulgular. SRA ve OA PSH ve RI degerlerinde gruplarda anlamli yukseklikler saptanirken (p 0,05). SRV akim hizlarinda anlamli bir bicimde yukseklik saptandi (p 0.05). Furthermore significant increase of CRV measurements was detected (p<0.05). Conclusion. We thought that the changes of PSV and RI parameter in CRA and OA depend on hypoxia with COPD causes systemic and local inflammatory metabolites due to distortion of retinal auto regulatory mechanism. The elevation increase CRV is attributed to amount of blood return to the ophthalmic vein by means of ocular blood flow increase, and to the increased central venous blood pressure related to COPD.
