Ağız Mukozası Epitelinde Psödoepitelyomatöz Hiperplazi
(Duzce University Faculty of Medicine, 2019) Kahraman, Devrim; Günhan, Ömer
Squamous epithelium covering the oral mucosa is open to a variety of irritations and may show aberrant reactive proliferations. These changes may create an abnormal clinical mass and histologically mimic neoplastic lesions. These reactions are called pseudoepitheliomatous hyperplasia or pseudocarcinomatous change. Exaggerated abnormal reactive changes may cause misdiagnosis of oral cancer in the mouth by inexperienced persons in oral pathology. On the other hand, due to histological similarities, also oral cancers may underdiagnosed wrongly as reactive lesions and lead to delays in cancer diagnosis and treatment. In this article, the causes of pseudoepitheliomatous hyperplasia and related specific diseases will be discussed. Additionally, the differential diagnosis of oral cancers from reactive lesions will be covered. The well knowing of the clinical features and a careful histological evaluation will prevent undesirable problems in the future. The information of the article is more useful for the pathologists; however, it will be helpful for the clinicians to know the problems and difficulties in the accurate diagnostic process.

INTRODUCTION: In this study, we aimed to present the clinical results of articular resurfacing prosthesis cases applied to cartilage problems of active patients who cannot be treated conservative and biological surgical methods. METHODS: From April 2007 to March 2014, 32 patients were treated with femoral resurfacing using the HemiCAP implant. Indication for treatment with HemiCAP implant was symptomatic cartilage lesion at the medial femoral condyle demonstrated by MRI or arthroscopy, which was ICRS grade 3–4 and size less than 4 cm2. Patients were evaluated according to VAS score, American Knee Society Score, clinical improvement. RESULTS: 32 patients ( 8 males, 24 females) evaluated in this study. Mean age was 53.1 ± 3.2 years. 18 ( %56.3 ) patients were operated from right knee while 14 ( %43.7) of patients from left. Follow-up time was between 24 and 30 months ( 26.6 ±1.9 ). The decrease in postoperative VAS compared to preoperative VAS was statistically significant ( p<0.01 ). A statistically significant increase was observed in postoperative American Knee Society Score compared to preoperative knee scores ( p<0.01 ). Preoperative function score was 46.5 ± 9.1, postoperative function score was 77.3 ± 7.7. A statistically significant increase was observed in postoperative knee function scores compared to preoperative knee function scores ( p<0.01 ). DISCUSSION AND CONCLUSION: The femoral resurfacing treatment in active patients with local cartilage damage clinically reduces symptoms and improves knee function in the early period.

Anestezistin Uyanik Kraniyotomi Uygulamalarındaki Yaklaşımı
(Turkish Society of Anaesthesiology and Reanimation, 2018) Özlü, Onur
Awake craniotomy, which was initially used for the surgical treatment of epilepsy, is performed for the resection of tumours in the vicinity of some eloquent areas of the cerebral cortex which is essential for language and motor functions. It is also performed for stereotactic brain biopsy, ventriculostomy, and supratentorial tumour resections. In some institutions, avoiding risks of general anaesthesia, shortened hospitalization and reduced use of hospital resources may be the other indications for awake craniotomy. Anaesthesiologists aim to provide safe and effective surgical status, maintaining a comfortable and pain-free condition for the patient during surgical procedure and prolonged stationary position and maintaining patient cooperation during intradural interventions. Providing anaesthesia for awake craniotomy require scalp blockage, specific sedation protocols and airway management. Long-acting local anaesthetic agents like bupivacaine or levobupivacaine are preferred. More commonly, propofol, dexmedetomidine and remifentanyl are used as sedative agents. A successful anaesthesia for awake craniotomy depends on the personal experience and detailed planning of the anaesthetic procedure. The aim of this review was to present an anaesthetic technique for awake craniotomy under the light of the literature.

COVID-19 ve Koagülopati
(Türkiye Klinikleri, 2020) Özlü, Onur
Critical COVID-19 patients caused by coronavirus 2 (SARS-CoV-2) is characterised by hypoxia, hyperinflamation besides coagulopathy and thrombosis. Venous, arterial and microvascular thrombosis are associated with poor prognosis. For the critical COVID-19 patients admittted to intensive care unit, the incidence of thrombotic complications were reported as 16-64%. Initial elevated Ddimer and fibrinogen levels are associated with thrombocytopenia and mild elevated prothrombin time. As the disease progress, disseminated intravasculary coagulopathy can develop in severe COVID-19 patients. Anticoagulant treatment with heparin is important for improving prognosis in COVID-19 patients who have high D-dimer levels and coagulopathy criterions. Monitoring of coagulopathy related parameters more than viral parameters and interventions related to coagulopathy prophylaxis and treatment managements are more important in terms of prognosis and mortality of COVID-19 patients than antiviral treatments.
Cretan Plus Protokolü Uygulanan Keratokonus hastalarında 1 yıllık dönemdeki Korneal aberasyon ve Optik kalite sonuçlarının değerlendirilmesi
(Türk Oftalmoloji Derneği İzmir Şubesi, 2024) Yavrum, Fuat; Özkoyuncu Kocabaş, Dilara; Özülken, Kemal
GİRİŞ VE AMAÇ:Çalışmamızın amacı Cretan plus protokolü (transepitelyal fotorefraktif keratektomi [t-PTK] sonrası korneal çapraz bağlama [CXL] ve konvansiyonel fotorefraktif keratektomi [PRK]), uygulanan keratokonus hastalarında, cerrahi sonrası korneal aberasyon ve optik kalite değişimini değerlendirmektir. YÖNTEM:Cretan plus protokolü uygulanan 16 keratokonus hastasının 20 gözü çalışmaya dahil edildi. Hastaların preoperatif, postoperatif 1., 6. ve 12. ay refraktif, topografik, ve optik kalite verileri Sirius topografi (CSO, Italy) cihazı ile değerlendirildi. Tüm hastaların aberasyon profili (yüksek sıralı aberasyonlar (HOA), vertikal koma, horizontal koma, vertikal trefoil, oblik trefoil ve sferik aberasyon) ile vertikal ve horizontal modülasyon transfer fonksiyonu (MTF) ve nokta dağılım fonksiyonu (PSF) şeklinde optik kalite parametreleri karşılaştırıldı. BULGULAR:Amsler-Krumeich keratokonus sınıflamasına göre, 6 (%31.2) göz evre I, 14 (%68.7) göz ise evre II keratokonus idi. Ortalama Kmax değeri ameliyat öncesi 51.16 ± 1.90 D’dan ameliyat sonrası 1. yıl 47.06 ± 1.68 D’e düştü (P<0.001). Ortalama düzeltilmemiş ve düzeltilmiş uzak görme keskinliği, korneal astigmatizma ve manifest sferik ekivalanda 1. yılda anlamlı azalma gözlendi (P<0.001). Ayrıca, Cretan plus protokolü uygulaması sonrası 1. Yılda HOA, vertikal koma ve sferik aberasyon değerlerinde anlamlı bir azalma görüldü (P<0.05). Tüm 1. yıl optik kalite değerlerinde artış gözlemlenmesine rağmen, sadece MTF 5, MTF 10 ve PSF değerlerinde istatistiksel olarak anlamlı artış izlendi (P<0.05). TARTIŞMA VE SONUÇ:Çalışmamızda Cretan plus protokolü ile keratokonus hastalarında 1. yılda refraktif ve topografik anlamlı değişiklikler yanısıra korneal aberasyonlarda azalma ve optik performansda artma gösterilmektedir.

Effects of Granisetron on Spinal Anesthesia-Induced Hypotension
(Anestezi Dergisi, 2021) Çataroğlu, C.K.; Alptekin, A.; Gezer, A.; Sayın, M.; Dönmez, A.
Objective: It was aimed to evaluate the effect of intravenous (IV) granisetron used for nausea and vomiting prophylaxis on hypotension and bradycardia caused by spinal anesthesia. Methods: 120 ASA 1-2 patients undergoing elective surgery under spinal anesthesia were randomly divided into Group G (Ganisetron; n=60) and Group P (Placebo; n=60) groups. Five minutes before spinal anesthesia, Group G received 1 mg intravenous granisetron diluted in 10 mL of isotonic sodium chloride solution and Group P received 10 mL of isotonic sodium chloride solution. Spinal anesthesia with hyperbaric bupivacaine 0.5%, 15 mg at the level of L4-5 was applied for both groups. Hemodynamic data, sensory and motor block parameters were recorded before and after spinal anaesthesia every 5 minutes during 20 minutes of surgery. Results: There was no difference in the demographic data of both groups. Although hemodynamic data showed a decrease in both groups according to initial values, blood pressure measurements in group G were significantly higher than the first measure values. There was no significant difference in heart rate values between the groups. Conclusion: Intravenous granisetron reduces hypotension after spinal anesthesia, but it has no significant effect on heart rate. © Copyright Anesthesiology and Reanimation Specialists’ Society.
