    (Professional Medical Publications, 2019) Özen, Özkan; Günaydin, Mücahit; Tosun, Alptekin; Coşkun, Zafer Ünsal; Aytekin, Kürşad; Takır, Selçuk
    Objective: Medications are generally administered by either the enteric or parenteral route. With parenteral administration, intramuscular (IM) is the preferred approach because it increases the bioavailability of the drug, acts more quickly than the enteric route. The aim of this study was to determine the rate of true dorsogluteal intramuscular drug injection and to determine the causes for application failures in practice by ultrasonography (US). Methods: The study was conducted from May 1 to May 30, 2017 in Giresun University Education and Research Hospital, Giresun, Turkey. We examined 60 patients who were administered dorsogluteal IM injection with a 38.1mm length needle. After the injection, localization of medications (whether intramuscular or subcutaneous adipose tissue [SAT]) was evaluated by Ultrasound. Results: Female/male ratio of the patients was 27/33, with a mean age of 39.78 +/- 2.16 years. Obese/ normal weight ratio was 20/40. The mean dorsogluteal area SAT thickness of obese and normal weight patients were 32.34 +/- 2.17 mm and 20.85 +/- 1.20 mm, respectively. In 23 of the patients, IM injected drug was observed in the SAT, while it was observed in the IM area in 37 patients. Medication was observed in IM area in 37 of 50 patients who dorsogluteal region SAT thickness was appropriate (SAT thickness lower than 33.1mm) for IM injection while it was seen in SAT area in 13 patients. Conclusions: SAT thickness values are important if IM drug injection is to be administered correctly. Unsuccessful IM injections may be seen even in patients with appropriate SAT thicknesses.

    Santral sinir sistemi tümörlerinin görüntülenmesi
    (Alanya Alaaddin Keykubat Üniversitesi, 2018) Tosun, Alptekin; Şerifoğlu, İsmail
    Çoğu santral sinir sistemi (SSS) tümörlerinin ve tümör olmayan lezyonların oldukça benzer görünümler sergilemesinden dolayı rutin Manyetik Rezonans Görüntüleme (MRG) sekanslarının özgüllükleri bunları ayırmada yetersizdir. SSS tümörlerinin ayırıcı tanısında anahtar unsurlar, lezyonun lokalizasyonu (intra- veya extra-aksiyel, infraveya supra-tentoriyal) ile birlikte hastanın yaşıdır. Multiparametrik MRG tekniklerini (Spektroskopi, Difüzyon Ağırlıklı Görüntüleme, Difüzyon Tensor Görüntüleme, Perfüzyon Ağırlıklı Görüntüleme, Fonksiyonel MRG), tümörün mikroskobik ve fonksiyonel davranışına ilişkin (hücresel yoğunluk, neo-vaskularizasyon, kapiller sızıntı ve metabolitler gibi) bilgiler sunar. İleri multiparametrik görüntüleme teknikleri SSS tümörü olan hastaların teşhisi, yönetimi ve takibinde kesin ve güvenilir invaziv olmayan bir yöntem sunar.

    The role of computed tomography signs in diagnosis of patients with small bowel obstruction
    (Alanya Alaaddin Keykubat Üniversitesi, 2018) Şerifoğlu, İsmail; Öz, İbrahim İlker; Tosun, Alptekin; Demir, Mustafa Kemal
    Aim: The goal of this prospective study is to evaluate the prognostic impact of computed tomography (CT) signs in the analysis of small bowel obstruction (SBO). Patients and Method: Sixty consecutive patients with acute abdominal pain who were examined using abdominal CT to diagnose SBO were included in the study. 47 patients of them (26 male; 21 female and mean age, 60 years), were evaluated. CT evaluation parameters were mesenteric congestion, transition zone, feces sign, intramural air and intraperitoneal free fluid. Results: There was a statistically significant association between the SBO diagnosis and CT findings for mesenteric congestion, transition zone and intramural air (p<0.05 for all). These CT signs had greatest sensitivity and positive predictive value (PPV) in diagnosis of SBO. The combination of mesenteric congestion, transition zone and intramural air showed a significant association in the diagnosis of SBO (p<0.05). Small bowel feces sign and intraperitoneal free fluid findings had no statistically significant value in the diagnosis of SBO (p>0.05). When three or more CT findings were seen together, there was a statistically significant association in the diagnosis (p<0.05). Conclusion: Mesenteric congestion and transition zone had the highest sensitivity and PPV in diagnosing SBO. The combination of mesenteric congestion, transition zone and intramural air and the presence of three or more CT signs markedly increase the specificity in diagnosis of SBO.
