A case of elephantiasis nostras verrucosa treated successfully by a new type of compressive garment
(2020) Mansur, A. Tulin; Ozker, Emre; Demirci, Gulsen Tukenmez; 32981199
Elephantiasis nostras verrucosa (ENV) is a clinical manifestation composed of hyperkeratotic, verrucous, and papillomatous lesions and dermal fibrosis, which complicate chronic lymphedema. There is currently no cure for ENV, however, several measures have been used to reduce lymphedema and the resultant pseudoepidermal hyperplasia. Supportive dressings and compression therapy still constitute an important part of the treatment. In this report, we present a 69-year-old male patient with ENV developed due to chronic lymphedema caused by venous insufficiency. After failure of healing with conventional two- and three-layered bandages, and elastic stockings, he was successfully treated by a new type of compression garment. We recommend this user friendly garment for prevention of frictional trauma, contact dermatitis, and secondary infection, which all may complicate compression treatments.

(2017) Altun, Dilek; Cinar, Ozlem; Ozker, Emre; Turkoz, Ayda; 0000-0003-2279-3083; 28183564; AAR-7467-2020
Study of objective: To compare the effects of oral tramadol + paracetamol combination on morphine consumption following coronary artery bypass grafting (CABG) in the patient-controlled analgesia (PCA) protocol. Design: A prospective, double-blind, randomized, clinical study. Setting: Single-institution, tertiary hospital. Patients: Fifty cardiac surgical patients undergoing primary CABG surgery. Interventions: After surgery, the patients were allocated to 1 of 2 groups. Both groups received morphine according to the PCA protocol after arrival to the coronary intensive care unit (bolus 1 mg, lockout time 15 minutes). In addition to morphine administration 2 hours before operation and postoperative 2nd, 6th, 12th, 18th, 24th, 30th, 36th, 42th, and 48th hours, group T received tramadol + paracetamol (Zaldiar; 325 mg paracetamol, 37.5 mg tramadol) and group P received placebo. Sedation levels were measured with the Ramsay Sedation Scale, whereas pain was assessed with the Pain Intensity Score during mechanical ventilation and with the Numeric Rating Scale after extubation. If the Numeric Rating Scale score was.>_.3 and Pain Intensity Score was >= 3, 0.05 mg/kg morphine was administered additionally. Measurements: Preoperative patient characteristics, risk assessment, and intraoperative data were similar between the groups. Main results: Cumulative morphine consumption, number of PCA demand, and boluses were higher in group P (P < .01). The amount of total morphine (in mg) used as a rescue analgesia was also higher in group P (5.06 +/- 1.0), compared with group T (2.37 +/- 0.52; P < .001). The patients who received rescue doses of morphine were 8 (32%) in group T and 18 (72%) in group P (P < .001). Duration of mechanical ventilation in group P was longer than group T (P < .01). Conclusion: Tramadol + paracetamol combination along with PCA morphine improves analgesia and reduces morphine requirement up to 50% after CABG, compared with morphine PCA alone.

Effectiveness Of Negative-Pressure Wound Therapy Compared To Wet-Dry Dressing In Pressure Injuries
(2022) Sahin, Ezgi; Rizalar, Selda; Ozker, Emre; 35022147
This study aims to compare the effects of Negative-Pressure Wound Therapy (NPWT) and wet-to-dry dressing on Stages 3 and 4 pressure injuries (PI), This study is a randomized controlled trial. A total of 30 patients with Stages 3 and 4 pressure injuries were included in the study. The patients were divided into two groups: NPWT group and the wet-to-dry dressing group. All patients received 3 rounds of treatment. Data were collected with a Patient Identification Form, Pressure Ulcer Scale for Healing (PUSH) Tool and the findings of the Three-Dimensional Wound Measurement (3DWM) device. We found that granulation tissue formation was more significant in the experimental group (p < .05), and that there was more significant wound shrinkage (p < .05) with a more significant decrease in the PUSH Tool scores (p < .05). The wounds were assessed with the tool and the 3DWM system. Device measurements were found to be correlated with PUSH Tool findings (p < .05). There was a significant correlation between device-measured granulation findings and PUSH Tool score results of the experimental group's third measurements (p < .05). We conclude that NPWT is an effective treatment method for pressure injuries, and 3DWM device is a useable wound assessment tool.
An Extraordinary Manifestation of Nodular Cystic Fat Necrosis
(2016) Demirci, Gulsen Tukenmez; Mansur, A. Tulin; Ozker, Emre; Demiralay, Ebru; https://orcid.org/0000-0002-9646-0719; 26894780; D-6031-2017
Nodular cystic fat necrosis (NCFN) is characterized by mobile subcutaneous nodules composed of necrotic adipocytes encapsulated by fibrous tissue. The classical presentation of NCFN is solitary or multiple, up to 40, discrete nodules scattered usually on the extremities or trunk. Here, the authors present an elderly woman who developed an unusual and striking clinical picture of NCFN, two months after a fall. The patient had a large indurated plaque and subcutaneous nodule with superposing necrotic ulcers. During debridement of the ulcers, nearly 100 small nodules popped up freely along with a brownish discharge. Deep in the ulcer, the authors discovered a dislocated nail that belongs to an old hip prosthesis. Histopathological findings of the nodules were compatible with NCFN.

Surgical Options in Complex Transposition of Great Arteries
(2016) Ayabakan, Canan; Saritas, Bulent; Ozker, Emre; Turkoz, Riza; Tokel, Kursad; 0000-0002-6759-1795; P-4569-2015; AAF-3253-2021
Background: In this study, we present our experience in selecting surgical approach for transposition of the great arteries and left ventricular outflow tract obstruction or aortic arch obstruction with ventricular septal defect and to report early and mid-term results. Methods: Between February 2007 and June 2012, a total of 18 patients (9 males, 9 females; median age 4.25 months; range, 12 days to 96 months) who were operated for transposition of the great arteries, ventricular septal defect, and left ventricular outflow tract obstruction or aortic arch obstruction were retrospectively analyzed. Results: Cardiac pathologies were transposition of the great arteries, ventricular septal defect and coarctation of aorta in four patients; transposition of the great arteries, ventricular septal defect and valvular pulmonary stenosis in two patients, and transposition of the great arteries, ventricular septal defect, valvular or subsubvalvular pulmonary stenosis in 12 patients. Arterial switch operation with ventricular septal defect closure and left ventricular outflow tract obstruction procedures were performed in nine patients, two of which were modified Konno operations. The other operations were arterial switch operation with ventricular septal defect closure and arcus reconstruction in four patients, Rastelli operation in three patients, and Nikaidoh operation in two patients. Median cardiopulmonary bypass and cross-clamp times were 228.5 min and 107 min, respectively. The median length of stay in the intensive care unit was 102.5 hours (range, 28 to 765 hours), while the median duration of intubation was 40.5 hours (range 17 to 275 hours). All patients were discharged within median seven days (range 5 to 55 days). The median follow-up was 37.7 months (range, 15 days to 74 months). Two patients who underwent Rastelli operation died due to low cardiac output in the intensive care unit. At the final echocardiographic examination, the median left ventricular outflow tract gradient was 12.4 mmHg (range, 2 to 38 mmHg) in the patients operated for left ventricular outflow tract obstruction, whereas the median descending aorta gradient was 13.5 mmHg (range, 7.8 to 28 mmHg) in the patients with arcus reconstruction. Only one patient with bicuspid neoaortic valve and posterior septal malalignment was reoperated due to a left ventricular outflow tract gradient of 38 mmHg. Conclusion: Our study results suggest that arterial switch operation is a preferable alternative, if the left ventricular outflow tract obstruction is resectable. Intraventricular re-routing procedures may be the choice in selected patients. We believe that choosing the optimal surgical technique demands appreciation of the particular anatomic features in each individual patient.
