Meniskopatili Hastalarda Patellar Tendonun Shear Wave Elastografi ile Değerlendirilmesi

Diz eklemi gibi kompleks ve yaralanmaya müsait olan bir eklemde yapıların birbiri ile uyumlu çalışması önemlidir. Meniskopati sonrası bu uyum bozulduğunda eklem biyomekaniği olumsuz etkilenecektir. Diz ekleminin stabilitesinde önemli olan ligamentum patella (LP)yı meniskopati sonrası değerlendirmeyi amaçladık. Çalışmamızda 18-45 yaş arasında olan 36 kişinin, 62 dizi değerlendirilmiştir. Manyetik rezonans görüntüleme (MRG) sonuçlarına göre menisküs lezyonu olan ve olmayan iki grup oluşturuldu. LPnin uzunluğunu MRG, kalınlığını ve ekojenitesini ultrasonografi (USG) ve elastisitesini de shear wave elastografi (SWE) ile değerlendirdik. Elde edilen verileri yaş, cinsiyet, vücut kitle indeksi (VKİ), egzersiz yapma, dominant taraf, sigara ve alkol kullanımı parametreleri ve Görsel analog skala (GAS), Western Ontario McMaster Üniversitesi osteoartrit indeksi (WOMAC) ve Pittsburgh uyku kalitesi indeksi (PUKİ) skorları açısından karşılaştırdık. Kontrol grubumuzda, LPnin uzunluğu arttıkça elastisitesinin de artığını, dominant tarafı sağ olanlarda LP sertliğinin daha fazla ve LPnin erkeklerde daha kalın olduğunu bulduk. Olgu grubumuzda, meniskopatinin görülme oranı erkeklerde daha yüksekti. Alkol kullananlarda LPnin daha sert ve kalın olduğu görüldü. LPnin kalınlığı arttıkça uyku esnasında ağrı skoru daha fazlaydı. Meniskopatili dize sahip kişilerde VKİ kontrol grubuna göre biraz daha yüksektir. LP uzunluğu ile elastisitesi arasında pozitif yönde bir ilişki vardır. Meniskopatili dizde LPnin kalınlığı artarken uzunluğu ve elastisitesi anlamlı bir şekilde değişmemiştir. LP kalınlığındaki artış hareket ve uyku esnasında ağrıyı arttırmıştır. Yaptığımız çalışma meniskopatili dizde LPyi SWE ile değerlendiren ön çalışma niteliğindedir

A design of dsPIC based signal monitoring and processing system

In this study, our objective is to develop a dsPIC based signal monitoring and processing system for analogue signals such as physiological originated signals (ECG, EMG, EEG, etc.). Microcontroller or microprocessor based monitoring systems can be much cheaper than PC based systems. However, the implementation of digital signal processing techniques using microcontroller is neither simple nor straight forward. The designed device consists of following hardware stages; a microcontroller adaptor board, dsPIC development board, (128×64) graphic LCD, and (4×4) keypad. Also, there are five different software modules which are ADC (Analog Digital Converter), FFT (Fast Fourier Transform), graphic LCD, keypad, and filter programs. The proposed device takes analogue signals via an ADC module and processes them with dsPIC by using keypad commands and then allows to plot at graphic LCD.In this study, our objective is to develop a dsPIC based signal monitoring and processing system for analogue signals such as physiological originated signals (ECG, EMG, EEG, etc.).

Meme Kanserli Kadınların Retrospektif Analizi: Batı Karadeniz Bölgesi Tek Merkez Onkoloji Klinik Verileri

Meme kanseri tüm dünyada kadınlardaki en sık kanser türü olup kadın kanserlerinin %30’nu oluşturur ve kadınlarda kansere bağ- lı en sık ölüm nedenidir. Bulen Ecevit Üniversitesi Onkoloji Bölümü Batı Karadenizdeki tek kanser merkezidir. 2000 ila 2010 yılları arasında kadınlarda meme kanserini retrospektif olarak araştırdık. Çalışmamızdaki populasyonun ortalam yaşı 49.90 ± 12 ’di ve ortalama takip süresi 4 ± 2 yıldı.Hastaların yaşa göre dağılımında %25’ini 40 yaş ve altı, %32’sini 40-50 yaş arası oluşturmaktayken kalan %43’de 50 yaş ve üzeri hastalar oluşturmaktaydı.En sık görülen kanser tipi 312 hastada saptanan invazif duktal karsinomdu (%80). Hastaların prognozuna baktığımızda; 309 hasta(%80) hastalıksız sağkalımda, 66 hastada (%17) progresyon, 7 hastada (%1,8) local nüks ve 15 hastada (%3,8) ölüm görüldü. Meme kanseri Batı Karadeniz bölgesindeki kadınlarda en sık görülen solid organ tümörlerden olup prognostik faktörler ve ileri evre hastalığı olanlardada uzun yaşam beklentisi açısından anlamlı bir fark saptanmadı. Hormonal pozitişik ve tedavi uyumu bu duruma en önemli katkıyı sağlamaktaydı.Breast cancer is the most common female cancer in the world wide with 30% of all women cancer and second most common cause of cancer death in women. Oncology department of Bulent Ecevit University Faculty of Medicine is the only cancer center in western part of Black Sea region. We investigated retrospectively our data of women breast cancer between the period of 2000 and 2010 in this region. The mean age of the study population was 49.90 ± 12 years and mean follow-up time was 4 ± 2 years. The distribution of patients by the age, 25% or patients under 40 years old, 32% between the 40-50 years old and 43% of them over the 50 years old. 92.6% of the patients were presented with a palpable mass. The most common type of breast cancer was invasive ductal carcinoma (IDC) in 312 patients (80%). Prognosis of the study population; 309 patients (80%) are surviving without any disease. Sixty-six patients (17%) had progression, 7 of 390 patients (1,8%) had local recurrence and 15 patients (3.8%) died. While the breast cancer is one of the most commonly seen solid organ tumors in Black Sea region and, based on the literature, no significant differences were observed for prognostic factors, longer life expectancy of the patients with advanced stage disease may be attributed to higher number of patients with hormonal positivity and therapy adherence

Variations and Factors Affecting the Benthic Foraminifer Assemblages Around the Submarine Springs Which are Known/Suggested to Be Present on the Eastern Aegean Coasts of Turkey Doğu Ege Denizi Türkiye Kiyilarinda Varliği Bilinen veya Düşünülen Deniz İçi Termal Çiktilar Çevresinde Gözlenen Bentik Foraminifer Topluluklarinda Belirlenen Değişimler ve Etkenler

© 2019, Hacettepe Universitesi Yerbilmler. All rights reserved.Benthic foraminifer assemblages have been known to include individuals with colored tests and morphological abnormalities on the coasts of Eastern Aegean Sea (Turkey) and Lesbos Island (Greece). For same reasons, surroundings of the thermal springs that are known to be present or suggested to be present were studied. Great qualitative and quantitative differences were observed in the distributions of the alien species, such as Coscinospira hemprichii, Euthomonacha polita, Peneroplis pertusus, P. planatus, Amphisorus hemprichii, Sorites orbiculus, S. variabilis, Cymbaloporetta plana, C. squammosa and Amphistegina lessonii, A. lobifera. The foraminifer assemblages around the thermal spring in Kuşadasi Bay were found to be rich in alien species, wheras, an exact opposite case was observed in Doğanbey Bay. The assemblages in Karaburun Peninsula and Ilica Cove also showed differences. The alien foraminifer Amphistegina lobifera, which is typical for the Aegean Sea, was not found in Ilica, but it was abundant in the recent sediment samples collected from northwest of Karaburun Peninsula. On the north, two thermal springs, with 40oC and 51oC temperatures, are closely located on the coast of Ilica Cape, near Aliağa (İzmir). Except Amphistegina lobifera, the alien species, such as, Peneroplis pertusus, P. planatus Amphisorus hemprichii and Sorites orbiculus, which are typical for Aegean Sea were not observed in the 13 samples collected from the region. Differences were found when the findings of the present study are compared with previous studies conducted in Kuşadasi, Doğanbey and northwest of Karaburun Peninsula, which worths attention. Peneroplis pertusus, P. planatus, Coscinospira hemprichii, Sorites orbiculus and Amphistegina lobifera individuals have been observed in the above mentioned localities, but none of them were found in Aliağa samples. These findings can be explained by the differences in environmental factors. For example, except Amphistegina lobifera, the above mentioned benthic foraminifer species have been observed around the thermal spring in Çeşme Ilica Cove, which had a temperature of 28.4oC. Southern Pacific and Red Sea originated Euthomonacha polita and Coscinospira acicularis individuals have been abundantly found in Kuşadasi Bay, Ilica Cove and northwest of Karaburun Peninsula. The absence of the mentioned five benthic foraminifers and any other alien foraminifer around the two thermal springs with 51oC and 40oC temperatures on Aliağa Ilica Cape, suggests that certain temperatures are required for these genera and species to live and the temperature values of the springs on Ilica Cape are too high. According to these findings, different genera and species are affected by the environmental conditions and they can, or not, continue to survive. Besides, numerous gypsum crystals were observed in sample A11 from samples of Ilica Cape, suggesting a thermal spring has been present in the past. In contrasts to high biodiversity of the foraminifer fauna, ostracod and mollusc fauna were very poor, which might be the result of sulphate found in the thermal water. Sulphate might have a negative effect on ostracod and molluscs, but not on foraminifers. It is evident that these alien foraminifer species are affected by the physical or chemical environmental conditions, can proliferate and expand in suitable regions, but cannot survive in certain locations. In addition, alien benthic foraminifers were also observed on the northwestern and western Aegean Sea (Greece), which did not show a diverse genera and species composition. However, detailed studies which should be conducted in the future will probably show the presence of a diverse alien foraminiferal fauna on these coasts
