Abstract	Abstract: BACKGROUND: Pain management and good sleep are essential for patients after surgical procedures. This study aimed to evaluate the effects of footbath on postoperative pain severity and sleep quality levels of patients who have undergone degenerative lumbar spine surgery. METHODS: Sixty patients were randomly assigned to the footbath intervention group or the control group. The intervention was a 20-minute footbath in 42°C water before patients fell asleep on the evening of the surgery day. On the morning of the surgery day and the morning of postoperative day, the patient's pain severity and sleep quality scores were obtained using the visual analog scale and the Visual Analog Sleep Scale. RESULTS: There was no significant difference between the pain severity scores of the study groups ( P > .05). The sleep quality level of the intervention group was statistically significantly higher than that of the control group ( P < .05). CONCLUSION: Consequently, a footbath is effective in increasing sleep quality levels of patients who have undergone degenerative lumbar spine surgery. It may be used as a simple and practical nonpharmacological nursing strategy for improving patients' sleep quality.

Abstract	Background: There is increasing research on the aging process of the cornea and its effect on the corneal parameters measured objectively. Nevertheless, the association of corneal epithelial thickness (CET) with age has yet to be fully illustrated. Purpose: We aimed to measure CET in healthy subjects to determine its age-related variation by using an ultrasound device. Patients and methods: A total of one hundred and three subjects were enrolled in this study and grouped according to age: Group < 30 years, 31-40 years, 41-50 years, 51-60 years, 61-70 years, and > 71 years. The CET and total central corneal thickness (CCT) of each subject were measured by the Sonogage Corneo-Gage Plus 2 (Cleveland, Ohio) ultrasound pachymeter. The relationships between thickness values, laterality, age groups, and gender were analyzed using the Jonckheere-Terpstra test. The Partial correlation test was employed to assess the effect of age on the CET and CCT. Results: The mean CET was 47.88±1.15μm, with no statistically significant gender-related difference between right and left eyes. In addition, the CCT difference detected between female and male eyes was insignificant. The difference in mean CET across age groups was statistically significant (p =0.029). The difference in mean CET of left eyes across age groups was statistically significant (p=0.031). The mean CET and left CET of the oldest group were significantly thinner than the younger groups. Conclusion: Ultrasound pachymeter of the corneal epithelium demonstrated that there was no correlation between age and CCT, or gender. The CET becomes thinner with age in the central zone in both genders and there is no difference between males and females. Based on these results, age has a negative effect on CET. These findings could offer further insight into age-related changes in the cornea.

Abstract	To determine the use of differential pressure difference (DPD), in air-puff differential tonometry, as a potential biomechanical measure of the cornea and elucidate its relationship with the intraocular pressure (IOP), central corneal thickness, corneal curvature, and age. This study comprised 396 eyes from 198 patients and was conducted at Acibadem University, School of Medicine, Department of Ophthalmology, Istanbul, Turkey. The central corneal curvature and refraction of the eyes were measured using an Auto Kerato-Refractometer (KR-1; Topcon Corporation, Tokyo, Japan). IOP and central corneal thickness were measured using a tono-pachymeter (CT-1P; Topcon Corporation, Tokyo, Japan), wherein two separate readings of IOP were obtained using two different modes: 1-30 and 1-60. The difference between these two readings was recorded as the DPD. The factors affecting the DPD were determined by stepwise multiple linear regression analysis. DPD varied over a dynamic range of - 3.0 to + 5.0 mmHg and was weakly correlated with the central corneal thickness (r = 0.115, p < 0.05). DPD showed no significant correlation with IOP 1-30 (p > 0.05). A weak but statistically significant (p < 0.05) positive correlation of DPD was observed with age (r = 0.123), Kavg (r = 0.102), and the CCT (r = 0.115). There was a significant correlation between DPD and Kavg, CCT, and age. There was no significant correlation between DPD and IOP 1-30. Age-related changes in the corneal ultrastructure may be a plausible explanation for the weak positive association between age and DPD. The proposed method may prove a valid non-invasive tool for the evaluation of corneal biomechanics and introduce DPD in the decision-making of routine clinical practice.

Abstract	In this study, energy, exergy and environmental-based design and multiobjective optimization of a novel solar-driven gas turbine-based multi-generation system is performed. For this purpose, a novel multi-generation system composed of a solar tower-driven gas turbine cycle, a Kalina cycle, an organic Rankine cycle, a single effect absorption refrigeration cycle, an electrolyzer and two domestic hot water heaters is developed. The system can produce electricity, heating and cooling for residential applications, domestic hot water, hydrogen and swimming pool heating, simultaneously from a single renewable energy source. A novel performance indicator, exergetic quality factor (EQF), for performance comparison and multiobjective optimization of multi-generation systems is also introduced. The system is analyzed with energy, exergy, EQF, environmental and exergoenvironmental measures. A detailed parametric study is also performed to analyze the effect of varying design parameters on the performance of the proposed system. The results show that the proposed system has 55.57%, 39.45% and 50.83% of energy efficiency, exergy efficiency, and EQF values, respectively; and inclusion of EQF into multiobjective optimization improves the multi-generation system performance.

Abstract	Background: Atypical serous chorioretinopathy can present with symptoms similar to those of other pachychoroid diseases; however, a proper differential diagnosis will prevent unnecessary intensive treatments. To this end, we report on the shallowness of anterior chamber and transitory anterior vitreous cells in a patient with atypical severe serous retinal detachment. Case presentation: A 42-year-old woman presented with unilateral visual loss accompanied by mild, vague eye pain for 4 days. Spectral-domain OCT scans of the left eye showed macular and peripapillary serous detachment. Optical biometry showed the clinically significant shallow anterior chamber. Conclusions: Severe central serous chorioretinopathy can show up in an atypical fashion with macular, extramacular, juxtapapillary serous detachments, temporary existence of anterior vitreous cells, clinically detectable decreased anterior chamber depth, and mild eye pain of short duration.

Abstract	Pathophysiological explanations for metamorphopsia associated with retinal pathologies generally focus on photoreceptor organization disruption. However, the retinal microarchitecture is complicated, and we hypothesize that other retinal cells may also be involved. Metamorphopsia has been widely studied in eyes with epiretinal membranes and we revisit the idea that Müller cell displacement causes retinal macropsia. A PubMed query and related article search for the macula ultrastructure under normal and pathological conditions revealed an enormous amount of information, particularly ultrahigh definition optical coherence tomography and other retinal imaging modality studies. Findings of these imaging studies support our hypothesis that Müller cells, and not cone photoreceptors, are primarily responsible for macropsia in eyes with epiretinal membranes. More specifically, we conclude that displacement of Müller cell endfeet, and not photoreceptor cones, is a more likely the explanation for retinal macropsia associated with epiretinal membranes.

Abstract	Background: The incidence of abdominal wall hematomas increased after the introduction of anticoagulant and antiplatelet drugs in clinical practice. These patients are usually old, and they have more than one comorbidity. Most spontaneous hematomas tend to limit itself and conservative treatment with close follow up is usually enough, but surgery is an option that should be decided critically. Unnecessary surgical interventions could worsen the situation. The present study aims to analyze the results of patients under anticoagulant/antiplatelet treatment and with spontaneous abdominal wall hematomas from surgeons' perspective. Methods: This is a retrospective study that the medical records of 43 patients who were under anticoagulant/antiplatelet therapy and consulted our general surgery clinic because of the spontaneous abdomen and abdominal wall hematoma between January-2016 and September-2018 were reviewed. Results: The findings showed that most of the cases were presented with abdominal pain. Thirty of these patients were female (69.7%). The mean age was 69.32 years. More than half of the patients (58.1%) were referred from the emergency department. All of the cases were under anticoagulant and antiplatelet treatment for several reasons. With presenting signs and symptoms and after evaluation of laboratory tests, computed tomography was performed to 30 patients (69.7%) as an initial test. USG and MRI were the other methods used. The most common diagnosis was rectus sheath hematoma (n=16; 37.2%) and followed by intestinal and colon wall, lumbar, psoas, pelvic and retroperitoneal hematoma in decreasing order. Among 43 patients, 39 patients (90.6%) followed with conservative treatment and two patients were treated with transcatheter arterial embolization. Two patients (4.6%) were died on day 1 and 11 after diagnosis. No surgery needed for all patients. Conclusion: Early recognition, hospitalization of risky patients, close follow-up of hemodynamic parameters, patients' response to conservative treatment and minimal invasive methods are key points. Conservative care is the choice of treatment, but surgery must always keep in mind in hemodynamic unstable patients.

Abstract	Amyand’s hernia is a very rare clinical condition characterized by the presence of a normal or inflammed appendix within the inguinal hernia sac. It may be present as an acute apendicitis inside the sac or incarcerated hernia. Sometimes it may be asymptomatic. We report a case of 70-year-old male patient that was presented to our emergency service with a huge right inguinal mass that was diagnosed as an incarcerated inguinal hernia and underwent operation. The intraoperative findings included small intestinal segment, large omental tissue and mobile cecum with healthy appendix inside the sac. There was no sign of strangulation. Lichtenstein herniorhaphy was done without appendectomy.
