Furkasyon perforasyonunda kullanılan materyallerin görüntüleme cihazlarındaki görünürlüklerinin değerlendirilmesi
Full text linkBackground: Variable radiographic techniques are used for postoperative evaluation of the materials used in furcation perforation. Since it is easily accessible clinically and the radiation dose which the patient is exposed to, is lower than the advanced imaging methods, intraoral imaging is applied. In cases that cannot be determined by 2D radiographs, cone beam computed tomography is more relevant because of the absence of superimpositions and allowing for multiplanar imaging. The aim of this study was to assess the diagnostic acceptability of the radiographic visibility of the materials used in furcation perforations and to find out which radiographic technique was efficient to view the materials.Methods: One hundred and twelve lower molar teeth were used according to the study criteria. Biodentin, BioAggregate, MTA and Endosequence were applied individually to the teeth, in order to repair the perforation zone. Periapical radiographs were obtained with Soredex Digora Optime with photostimulated phosphor plates. Other radiographic images were obtained using Planmeca Dixi 3 CCD, while CBCT images were obtained using Morita Veraviewepocs 3D R100. An endodontist and two dentomaxillofacial radiology specialists evaluated the images of CBCT and periapical radiographs. Teeth were evaluated randomly for the visibility of the repair materials in furcal perforations and scored.Results: MTA and Biodentine presented low image clarity while Bioaggregate and Endosequence had high image clarity. Morita Veraviewepocs 3D R100 depicted the highest sharpness, but no difference was observed between Soredex Digora Optime and Planmeca Dixi 3 devices.Conclusion: In the postoperative follow-up of the materials used in the treatment of furcation perforations, the usage of CBCT and the use of Bioagregate and Endosequence, which provide the best image clarity, has been suggested.Amaç: Furkasyon perforasyonunda kullanılan materyallerin post operatif değerlendirilebilmesi için çeşitli radyografik tekniklerden faydalanılmaktadır. Klinik şartlarda kolay erişilebilir olması ve hastanın maruz kaldığı radyasyon dozunun ileri görüntüleme yöntemlerine göre düşük olması nedeniyle intraoral görüntülemelere başvurulmaktadır. 2 boyutlu radyografilerle belirlenemeyen durumlarda ise süperpozisyonların olmaması ve multiplanar görüntülemeye olanak vermesi nedeniyle konik ışınlı bilgisayarlı tomografiler daha yararlı olmaktadır. Bu çalışmanın amacı furkasyon perforasyonlarında kullanılan materyallerin radyografideki görünürlüklerinin diagnostik açıdan kabul edilebilirliğini ve bu malzemelerin görüntülenmesinde hangi cihazın daha etkili olduğunu değerlendirmektir. Gereç ve Yöntemler: Çalışma kriterlerine uygun 112 alt molar diş seçilmiştir. Perforasyon bölgesini tamir etmek için dişlere ayrı ayrı Biodentine, BioAggregate, MTA ve Endosequence uygulandı. Periapikal radyografiler fosfor plaklarla Soredex Digora Optime ile, ve Planmeca Dixi 3 CCD kullanılarak, Konik Işınlı Bilgisayarlı Tomografi (KIBT) görüntüleri ise Morita Veraviewepocs 3D R100 kullanılarak elde edilmiştir. Bir endodontist ve iki ağız, diş ve çene radyolojisi uzmanı KIBT görüntülerini ve periapikal radyografi görüntülerini değerlendirmiştir. Dişler tamir malzemelerinin furkal perforasyonlarda görünürlüğü açısından rastgele değerlendirmeye alınmış ve skorlanmıştır. Bulgular: MTA ve Biodentine düşük görüntü netliği sunarken Bioaggregate ve Endosequence’ın yüksek görüntü netliğine sahip olduğu görüldü. Morita Veraviewepocs 3D R100 en yüksek netliği gösterirken Soredex Digora Optime ve Planmeca Dixi 3 cihazları arasında fark gözlenmemiştir. Sonuç: Furkasyon perforasyonlarının tedavisinde kullanılan materyallerin postoperatif takibinde, KIBT'nin kullanılmasını ve en iyi görüntü netliğini sağlayan Bioagregate ve Endosequence kullanmanılması önerilebilir bir sonuç olarak bulunmuştur

Viral hepatit veya sifiliz ile koiinfekteolgular sadece HIV ile infekte olgulara oranla daha yaşlıydı ancak gruplar arasında cinsiyet, antiretroviral tedavi (ART) deneyimi, CD4T lenfosit sayısı açısından anlamlı fark olmadığı görüldü (sırasıyla p= 0.013, p= 0.106, p= 0.542 ve p= 0.421). TPHA ve anti-HAV IgGseropozitifliği, ESE olgularında ESE olmayan olgulara göre anlamlı oranda daha yüksekti (sırasıyla, p< 0.001 ve p= 0.035).Sonuç: Kliniğimizde takip edilmekte olan HIV pozitif olgularda HBV, HCV ve HAV seroprevalansı genel popülasyondaki oranlara benzerbulunmuştur. Öte yandan HIV ile infekte ESE olgularının ESE olmayan olgulara oranla daha yüksek TPHA ve anti-HAV IgG seropozitifliğine sahip oldukları görülmüştürThe importance of sexually transmitted infections such as viral hepatitis and syphilis has increased relatively with prolonged life expectancy in HIV-positive cases. The aim of this study was to investigate the seroprevalence of viral hepatitis and syphilis coinfection in HIV-positive cases followed in our clinic. Materials and Methods: This retrospective, cross-sectional, single center study included 98 HIV-infected cases who were followed up in our clinic between January 2018 and November 2019. Demographics, physical examination findings, CD4 T lymphocyte count, HCV RNA, HBsAg, anti-HBcIgG, anti-HBs, anti-HCV, anti-HAVIgG, RPR and TPHA test results were obtained retrospectively from the patients’ files. Results: Median age of the patients was 33.5 (24-44) years, 73 (74.5%) were males, 13 (13.3%) were foreign nationals, 69 (70.4%) were treatment naive, 20 (20.4%) were male sex with male (MSM) and 5 (5.1%) had a history of intravenous drug addiction. The most common transmission route was heterosexual intercourse, and median CD4 T lymphocyte count was 249.5 cells/mm3 (145-358). Overall, 15 (15.3%) of the cases had at least one co-infection. The most common co-infections were HIV/syphilis and HIV/HBV coinfections (13.3% (n= 13) and 4.0% (n= 4), respectively). Only one case had HIV/HBV/syphilis coinfection while HIV/HCV coinfection was not found in this population. The rate of effective HBV vaccination was 26.5%, previous HBV infection was 14.3% and the prevalence of isolated anti-HBc was 3.9%. Cases coinfected with viral hepatitis or syphilis were older than those infected with HIV alone, but there were no significant differences between the groups in terms of sex, antiretroviral therapy (ART) experience, and CD4 T lymphocyte count (p= 0.013, p= 0.106, p=0.542 and p=0.421, respectively. TPHA and anti-HAV IgG seropositivity were significantly higher in MSM cases than in non-MSM cases (p< 0.001 and p= 0.035, respectively). Conclusion: Seroprevalence of HBV, HCV and HAV in HIV-positive cases followed in our clinic were similar to those in the general population. On the other hand, HIV-infected MSM patients had higher anti-HAV IgG and TPHA seropositivity than non-MSM cases
Investigation of neuroprotective and therapeutic effects of hesperidin in experimental spinal cord ınjury
Full text linkTo investigate the neuroprotective and therapeutic efficacy of hesperidin against secondary damage following traumatic spinal cord injury. MATERIAL and METHODS: A total of 32 male Wistar albino rats weighing 250–300 g were randomly divided into four groups (n=4): group I, control group; group II, sham group; group III, preconditioning group, and group IV, treatment group. A rat model of spinal cord injury was established by dropping a weight of 100 g/cm on the spinal cord exposed at T7–T10 with dorsal laminectomy. In neurological examination after the trial period, inclined planed test, modified Tarlov scale, and finger extension test were performed. Furthermore, the bioefficacy of hesperidin was investigated histopathologically, biochemically, and immunohistochemically using blood and tissue samples obtained from the experimental animals.RESULTS: Neurological examination following spinal cord injury revealed that hesperidin significantly contributed to improvement in the 24-hour period. Biochemical analyses revealed that hesperidin showed anti-inflammatory effects by decreasing IL-1β and TNF-α levels at the 24th hour as well as strong antioxidant activity by increasing TAS levels in groups III and IV. Histopathologically, hesperidin reduced hemorrhage, laceration, axonal and neuronal degeneration, necrosis, inflammatory reaction, and edema in groups III and IV. Immunohistochemically, hesperidin reduced the number of caspase 3-positive apoptotic cells in groups III and IV.CONCLUSION: Hesperidin showed antioxidant, anti-inflammatory, and anti-apoptotic effects during the acute period following spinal cord injury; thus, hesperidin shows neuroprotective and therapeutic efficacy in spinal cord injury
Comparison eCAP and behaviour thresholds in post lingual medel cochlear implant users
Full text linkAim: Our purpose with this study is to determine the most effective and suitable cochlear implant programming method for CI users’
implants to experience quality hearing and for the users to achieve efficiency from their implants.
Materials and Methods:Twenty-five cochlear implant users with post lingual progressive hearing loss were included in the study.
Twelve electrodes’ ART (auditory nerve response telemetry) thresholds were determined and were statistically analyzed to be
evaluated in the study. For 12 electrodes whose AutoART threshold was determined, the MCLs (most comfortable loudness) were
determined behaviorally.
Results: No correlations were found between the 12 electrodes and AutoART. It was seen that there was a correlation between the
pure tone average obtained from 500-1000-2000 and 4000Hz and the speech reception threshold.
Conclusion: The use of two test batteries together to determine thresholds can be helpful in the programming of the speech
processor. The more audiologists work with cochlear implant patients and do programming, the more they accumulate data and
gain occupational experience. With the occupational experience acquired in this manner, more accurate programming can be done
Kilis keçilerinde farklı dönemlerdeki besleme uygulamalarının bazı verim özellikleri üzerine etkileri
No full textAims: In this study, the effects of supplementary feeding during gestation
and lactation period on birth and weaning weights of kids and milk yield of
dams in Kilis goats were investigated.
Methods and Results: In the study, experimental goats were divided into
three groups as control group, short-term feeding (STF) group and longterm feeding (LTF) group. The control group was kept under breeder’s
management conditions. Supplementary feed of 750 g/head/day were
given to the goats from the last 20 days of gestation to 90th days after birth
in the STF group, and from last 40 days of gestation to the end of lactation
in LTF group. At the end of the experiment, the highest lactation period
was 220.2 days in the LTF group, followed by STF and control groups (P
<0.05). Likewise, in the LTF and STF groups, the lactation milk yield, which
was determined as 466.2 and 426.3 liters respectively, was higher than the
control group (316.4 liters) (P <0.05).
Conclusions: It was concluded that supplementary feeding during
gestation and lactation periods caused an increase in milk yield and
lactation length of Kilis goats.
Significance and Impact of the Study: At the end of study, it can be stated
that if supplementary feeding is made during gestation or lactation, milk
yield characteristics of Kilis goats will be improved. Suckling period for the
goats is the period when pasture conditions are good. For this reason, even
in the goats managed only in the pasture, milk yield of mothers is sufficient
for multiple born kids.Amaç: Bu çalışmada Kilis keçilerinde, gebelik ve
laktasyon dönemlerinde ek yemleme uygulamalarının
doğum ve sütten kesim ağırlıkları ile anaların süt
verimleri üzerine etkileri araştırılmıştır.
Yöntem ve Bulgular Bu projede deneme materyali

besleme grupları olarak üç gruba ayrılmışlardır. Kontrol
grubu yetiştirici koşullarında yönetilmiştir. Kısa dönem
besleme grubunda gebeliğin son 20 gününden
başlayarak doğum sonrası 90. güne kadar, uzun süreli
besleme grubunda ise gebeliğin son 40 gününden
başlayarak laktasyon süresince keçilere günde 750 g/baş
kesif yem verilmiştir. Deneme sonunda en yüksek
laktasyon süresi 220.2 gün olarak uzun süreli besleme
grubunda olmuş bunu kısa süreli besleme grubu ve
kontrol grubu takip etmiştir (P <0.05). Benzer şekilde
uzun süreli ve kısa süreli besleme gruplarında laktasyon
süt verimleri sırası ile 466.2 ve 426.3 litre olarak
belirlenmiş ve kontrol grubundan (316.4 litre) daha
yüksek olmuştur (P <0.05).
Genel Yorum: Çalışmada gebelik ve laktasyon
dönemlerinde ek yemleme uygulamalarının laktasyon
süresi ve süt veriminde artışa neden olduğu sonucuna
varılmıştır.
Çalışmanın Önemi ve Etkisi: Bu çalışma sonunda Kilis
keçilerinde gebelik ve laktasyon dönemlerinde ek
yemleme yapılırsa keçilerin süt verim özelliklerinin
iyileşeceğini göstermektedir. Bölgedeki oğlaklar için süt
emme dönemi mera şartlarının iyi olduğu zaman
dilimindedir. Bu nedenle, hayvanlar sadece merada
yönetilseler dahi, annelerin süt verimleri çoğuz doğan
oğlaklar için yeterli olmaktadır
Challenges in the clinical and radiological differential diagnosis of cerebrovascular events and malignant primary brain tumors: reports from a retrospective case series
Full text linkAIM: To reveal difficulties in differential diagnosis of some cases of cerebrovascular events (CVEs) and malignant primary brain tumors (MBTs) even a multidiciplinary evaluation in grand rounds. MATERIAL and METHODS: This study retrospectively analyzed the patient archives from January 2017–December 2019. The records of 572 patients discussed in these meetings were examined. A total of 8 patients having a challenge in differential diagnosis were detected. RESULTS: This study has included 8 cases in which neurology−neurosurgery−neuroradiology clinicians have difficulty in differentiating CVE and MBT. In the present study, three patients were evaluated with a preliminary diagnosis of hemorrhagic CVE in the emergency room. Since degradation products of hemoglobin have prevented advanced imaging methods to diagnose in two patients, these patients have been followed closely. The correct diagnosis could be made through the scan performed during control follow-ups The preliminary diagnosis of seven patients was CVE, but they received the MBT diagnosis during the follow-up. One patient was thought to have MBT initially; however, he/she was diagnosed with CVE after an advanced examination and close follow-up. CONCLUSION: Despite developing medical imaging methods and diagnostic studies, there are still some difficulties in making differential diagnosis of CVEs and MBTs. In some patients, further examination and imaging methods may be needed such as magnetic resonance imaging-spectroscopy (MRI-S), perfusion magnetic resonance imaging (Per-MRI), digital substratioangiography (DSA). Despite all these neuroradiological examinations and multidiciplinary evaluation, distinction between CVE and MBT may be difficult, and medicolegal problems may be encountered
Does B12 deficiency lead to syringomyelia?
Full text linkA 20-year-old female was admitted to our clinic with the complaint of gait disturbance, which started three months ago and slowly progressed. Her medical history was non-specific. Her initial complaints began with numbness in her right foot and, then, under the left knee. Over time, activities such as sitting and standing up and climbing stairs became more difficult, and urinary incontinence started. Her physical examination revealed an ataxic gait pattern. Bilateral lower extremity strength was 4/5. Bilateral patellar reflexes were hyperactive. Bilateral Achilles reflexes were hypoactive. The plantar reflex was unresponsive at right and flexor at left. The superficial sensation
was normal at lower extremities; however, there was a loss of deep sensation. The Romberg sign was positive. Laboratory test revealed that hemoglobin was 11 g/dL
(reference: 13.6 to 17.2), mean corpuscular volume was 124 fL (reference: 80.4-95.9), serum vitamin B12 level was 80 pg/mL (reference: 190911), and liver and kidney function tests, electrolyte levels, blood glucose, glycosylated hemoglobin, C-reactive protein, and erythrocyte sedimentation rate were within normal limits. Nerve conduction studies showed that bilateral common peroneal, tibial, ulnar, and
median nerve sensory and motor conduction were within normal limits
