    Changes in olfactory function and olfactory bulb after treatment for acromegaly
    (Springer, 2021) Degirmenci, Nazan; Bektas, Hasan; Şentürk, Erol; İlhan, Muzaffer; Gunaldi, Alev; Yetis, Esra Ummuhan Mermi; Eren, Sabri Baki
    Purpose This study aimed to investigate the olfactory functions of the acromegaly patients and to discuss the possible causes of olfactory dysfunction in acromegaly patients. Methods A case-control study was carried out in a tertiary referral center. 52 patients with acromegaly (Acromegaly group) and 52 healthy individuals (Control group) were included in the study. All acromegaly patients included in the study were in the late postoperative period. The Connecticut Chemosensory Clinical Research Center (CCCRC) test was carried out and olfactory bulb (OB) volumes were measured in both of the groups. Results There was a significant difference between the mean CCCRC total scores of the acromegaly and control groups (p = .000). The mean of right and left OB volumes in the acromegaly group was significantly higher than the control group (p = .004) Conclusion In this study, we found that acromegaly patients are likely to experience olfactory dysfunction. It is important to examine these patients' olfactory functions at the time of diagnosis and clinic follow-up.

    Determination of congenital absence of palmaris longus tendon with clinical examination and ultrasonography
    (Springer France, 2021) Fidan, Nurdan; Turk, Ayla Cagliyan; Yetis, Esra Ummuhan Mermi; Yucesoy, Cuneyt
    Objectives The tendon of the palmaris longus is commonly used as a tendon graft in many reconstructive surgeries. Palmaris longus absence (PLA) was found in 15% among individuals worldwide. In this prospective study, we aimed to conduct an incidence study in which physical examination methods were confirmed by ultrasonography in PLA, and to evaluate the relationship of absence with age, gender, laterality and dominant hand. Methods The study included 490 cases. They were initially tested to evaluated by physical examination using the Schaeffer's and Hiz-Ediz test for the assessment of the palmaris longus tendon. Additional ultrasonography was performed to confirm its absence in 129 wrists of 78 cases whose tendons could not be visualized or palpated. Results The incidence of tendon absence was 13% by physical examination methods. According to the final results when we added ultrasonography to physical examination methods, the incidence of unilateral, bilateral and overall absence of the palmaris longus were 5%, 9% and 11% respectively. There was no statistically significant difference between individuals with and without PLA in terms of gender, side, age and dominant hand (p = 0.796, p = 0.622, p = 0.397 and p = 0.187, respectively). However, bilateral PLA was statistically significantly higher than unilateral in both genders (p = 0.011). Conclusions We think that agenesis should be proven accurately by ultrasonographic examination for the final result before any surgical procedure with palmaris longus tendon. Furthermore measuring the diameter of the palmaris longus tendon by preoperative ultrasonography can be useful for surgeons who plan a procedure that requires specific measurements.

    Is the presence of echo-rich periportal cuffing in the liver indicator for abdominal inflammation in pediatric patients?
    (Soc Romana Ultrasonografe Medicina Biologie-Srumb, 2019) Fidan, Nurdan; Yetis, Esra Ummuhan Mermi; Murat, Muammer; Yucesoy, Cuneyt; Turgal, Ebru; Metin, Mehmet
    Aims: Hyperechoic/echo-rich periportal cuffing (ErPC) is defined as an increase in echogenicity relative to the adjacent liver parenchyma. Thickening in the periportal area may occur with proliferation of bile ducts, hemorrhage, oedema, fibrosis, inflammatory changes or a combination of these. The aim of this study is to determine which intraabdominal inflammatory diseases arc associated with the presence of ErPC in the pediatric population and to calculate the sensitivity and specificity of this finding. Material and methods: In this prospective study 200 consecutive children who underwent abdominal ultrasonography (US) were included: group 1, the patient group (100 children with appendicitis, gastroenteritis, mesenteric lymphadenitis, intestinal infection, terminal ileitis and imagination as cause of intra-abdominal inflanunation) and group 2, the control group (100 children). Results: The ErPC was positive in 74 (74%) cases in the patient group and in 3 (3%) in the control group. According to final diagnoses, we found ErPC in most of patients with gastroenteritis (16/17), perforated appendicitis (10/11), mesenteric lymphadenitis (5/6) and acute appendicitis (27/37). The sensitivity of ErPC in indicating intra-abdominal inflammation was 0.80 and its specificity was 0.87. No significant correlation between ErPC and age, gender and CRP was found but a moderate and significant positive correlation between ErPC and WBC (p=0.010; r=0.255) was detected. Very good concordance between observers in terms of the presence of ErPC on abdominal US was found (concordance 97% and kappa 0.93). Conclusions: We consider that the presence of ErPC in pediatric patients, when evaluated alongside clinical and laboratory findings, has a high sensitivity and specificity for inflammatory intra-abdominal pathology.
