RESUMEN
OBJECTIVES: This study compared the impact of transoral rigid laryngoscopy (TORL) and transnasal flexible laryngoscopy (TNFL) methods on intraocular pressure (IOP). METHODS: This study included 100 patients, with 50 patients undergoing a TORL, and 50 patients a TNFL. Before procedure IOP values were recorded by an ophthalmologist using Icare Pro tonometry, also immediately post procedure, and at the 15th, 30th and 60th minute after laryngoscopy. RESULTS: Both groups were similar in terms of age, gender, mean body mass index (BMI), and pre-laryngoscopy IOP values. When the TNFL and TORL groups were compared, no significant differences were observed between pre-laryngoscopy, and 60th minute IOP values (p = 0.891, p = 0.149, respectively). IOP values measured immediately after laryngoscopy, and at the 15th and 30th minute were significantly higher in the TORL group (p < 0.001, p < 0.001, p = 0.002, respectively). CONCLUSIONS: We demonstrated higher IOP fluctuations in the TORL group, when compared to the TNFL group. For this reason, TNFL may be considered a safer method for evaluating laryngeal tissues in conditions that require lower IOP fluctuation as in glaucoma. However, further studies are required to clarify the exact effects of IOP fluctuations during TNFL and TORL in patients with glaucoma.

INTRODUCTION: Nasal septal deviation (NSD) is one of the major causes of upper airway obstruction. Chronic hypoxia and hypercapnia due to NSD may affect the choroidal blood flow and may change the choroidal thickness (CT). In this study, the authors aimed to research the assessment of CT before and after septoplasty in patients with NSD. METHODS: Ninety-two patients who underwent septoplasty surgery with the diagnose of nasal septum deviation and 58 patients for control group were enrolled to the study. CT values measured before and three months after septoplasty surgery. RESULTS: CT values were subfoveal 272.51â±â27.62, nasal 245.50â±â21.22, temporal 248.35â±â30.25 and subfoveal 232.09â±â44.17, nasal 222.09â±â38.82,temporal 227.12â±â28.80 for the control and NSD groups, respectively (Pâ<â0.001). Also choroid thickness values (subfoveal 232.09â±â44.17, nasal 222.09â±â38.82, temporal 227.12â±â28.80; subfoveal 252â±â18.90, nasal 228â±â22.12, temporal 240â±â25.80) were significantly different in patients with NSD, before and after septoplasty procedure, respectively (Pâ<â0.001). CONCLUSION: To the authors' knowledge this is the first study investigating choroid thickness measurements before and after septoplasty in patients with NSD. We found significant correlation between NSD and CT. After septoplasty surgery at 3rd month, CT increased significantly in comparision with the preoperative values.

This study aimed to compare the results of AP screws, PA screws and posterior buttress plate used in posterior malleolar fixation of trimalleolar fractures. In this study, the data of 104 trimalleolar fracture cases treated surgically between October 2011 and January 2014 were extracted from hospital records. Patient demographics (age, gender, body mass index), the presence of syndesmotic injury, fracture type (according to the Lauge-Hansen classification), the size of posterior malleolar fragment (measured on lateral radiographs) were recorded. The patients requiring postoperative care for at least a year were invited to attend an evaluation of functional and radiological outcomes. At the final follow-up examination the functional evaluation was made by using AOFAS scores, VAS scores during walking, and dorsiflexion restrictions as compared with the unaffected side. As for the radiological evaluation, the patients were assessed according to the presence of a gap or step by the direct use of graphies following the fixation and with regard to the osteoarthritic development in alignment with the Bargon criteria. A total of 67 patients met the study inclusion criteria; 20 cases in the AP screw, 13 cases in the PA screw and 34 cases in the plate group. The mean follow-up period was 14.4 ± 2.23 months in AP, 16.3 ± 2.56 months in PA and 17.1 ± 3.01 months in the plate group. Better AOFAS scores were obtained in the PA group and the plate group compared to the AP screw group (p < 0.001). No statistically significant difference was found between the groups in respect of VAS scores during walking and dorsiflexion restriction. Better radiological reduction was observed in the PA screw group and the plate group (p < 0.001).

The aim of this study was to compare the graft patency rates among patients who had a previous history of percutaneous coronary intervention (PCI) followed by coronary artery bypass grafting surgery (CABG) with the patients who had experienced CABG surgery alone. The 69 patients who were included in the study had a history of bare metal stent implantation prior to CABG (group 1). The coronary angiography results were compared with 69 patients who had a previous history of CABG (group 2). Graft patency rates of the left anterior descending artery and circumflex anastomoses are statistically significant for both groups, whereas the right coronary artery anastomoses are not statistically significant (p = 0.008; 0.009; 0.2). Graft patency rate of LIMA-LAD anastomoses was 43.9 ± 10.8 % in group 1 and 86.2 ± 6 % in group 2 for means of 60 months (p = 0.0001) and circumflex coronary artery anastomosis is 28.9 ± 0.9 % in group 1, 65.7 ± 10.8 % in group 2 (p = 0.0001) and the right coronary artery anastomosis is 37.2 ± 13.6 % in group 1, 56.4 ± 8.9 % in group 2 (p = 0.0001). The graft patency rates of coronary arteries without previous stent implantation were higher than the patients with previous stent implantation and experienced CABG. The results suggest that prior PCI may induce atherosclerotic events in the vessel that can adversely affect graft patency after surgery.

BACKGROUND: Choosing a good anastomotic site is crucial during surgical revascularization of the right coronary artery (RCA) system. In many instances of distal and/or sequential main trunk disease, either the right posterior descending coronary artery (RPDA) or distal part of the right main coronary artery (DRCA) is preferred as the target vessel. In this article, the saphenous vein graft (SVG) patency is compared between these two main targets in the long term. MATERIALS AND METHODS: Postoperative control coronary angiograms were obtained and assessed from 452 patients undergoing conventional on-pump coronary artery bypass grafting with either a DRCA (n = 305) or a RPDA graft (n = 147) after an average postoperative period of 5.8 ± 4.3 years (range: 2 months-20 years; a total of 2,627 patient-years). RESULTS: The overall graft patency was 60%. The 15-year patency rate was better for the DRCA grafts than that for the RPDA grafts (32 ± 5% vs. 19 ± 6%, respectively; p = 0.001), irrespective of target vessel caliber. Other factors adversely influencing the long-term graft patency were poor target vessel quality (p = 0.002) and hypercholesterolemia (p = 0.01). On the other hand, target vessel diameter, diabetes mellitus, hypertension, chronic renal insufficiency, obesity, peripheral arterial disease, or SVG quality were not associated with poor long-term graft patency in these patients having distal-type RCA disease. CONCLUSIONS: In the presence of distal and/or sequential right coronary disease, DRCA may be the target vessel of choice for bypass grafting, rather than the RPDA, mainly for better long-term SVG patency rates in this location.

BACKGROUND: The aim of this study was to examine the predictive ability of admission neutrophil/lymphocyte ratio (NLR) for predicting amputation in patients with acute limb ischemia who underwent embolectomy. METHODS: We retrospectively analyzed the clinical, hematologic, and amputation data of 254 patients who had undergone embolectomy for acute limb ischemia. There were 152 (52%) men and 93 (48%) women, with a mean age of 66.04 ± 13.30 years. The admission NLR was determined by dividing the absolute neutrophil count by the absolute lymphocyte count. The primary end point was determined as amputation and death. RESULTS: The mean duration of follow-up was 26 months. During the follow-up period, there were 18 (7%) amputations within 30 days of surgery and 36 (15%) amputations over a mean follow-up of 26 months. Based on multivariate logistic regression modeling, no arterial back bleeding and preoperative NLR were observed to be independent risk factors for amputation within 30 days of surgery, and no arterial back bleeding and preoperative NLR were observed to be independent risk factors for midterm amputation for the same time period. A NLR of ≥5.2 was taken as the cutoff based upon the receiver operating characteristic. In receiver operating characteristic curve analysis, a NLR ≥5.2 had 83% sensitivity and 63% specificity in predicting amputation within 30 days of surgery and 63% sensitivity and 63% specificity in predicting midterm amputation. CONCLUSIONS: An elevated NLR is associated with a poorer limb survival after embolectomy. This simple, inexpensive test may therefore be added to risk stratification of these high-risk patients.

BACKGROUND: We have retrospectively analyzed the results of the operations made for aortic infective endocarditis with mitral involvement in a single center in 19 years. METHODS: From May 1992 to January 2011, we have operated on 72 patients with infective endocarditis of the aortic valve with mitral valve involvement. Fifty-two patients (72.2%) were male and the mean age was 40.5 ± 15.5 (9-73) years. The blood cultures were positive in 33 patients (45.8%) and the most commonly identified microorganism was Streptococcus. Nine patients (12.5%) had prosthetic valve endocarditis. The mean duration of follow-up was 6.8 ± 4.7 (0.1-16.9) years, adding up to a total of 156.1 patient/years. RESULTS: A total of 155 procedures were performed on these 72 patients. The most commonly performed procedure was aortic valve replacement, in 63 patients (87.5%). Aortic annular involvement was present in 9 cases (12.5%). In-hospital mortality was seen in 13 patients (18.1%). Postoperatively, 13 (18.1%) patients had low cardiac output, 9 (12.5%) had heart block, and only 1 of them required permanent pacemaker implantation. The actuarial survival rates for 1, 5, and 10 years were 96.4% ± 2.5%, 84.4% ± 5.1%, and 77.4 ± 6.7%, respectively. CONCLUSIONS: Double-valve endocarditis is a serious condition and the surgeon must be aware of the high rates of mortality and morbidity in these patients. Although no association was found, heart blocks and septic embolization must be handled with caution. The patients generally do well after surgery, and recurrences and reoperations decrease by the second year after operation.

PURPOSE: In the present study we evaluate the corneal endothelium using specular microscopy in patients with obstructive sleep apnea syndrome (OSAS). METHODS: The study included a total of 100 patients including 35 patients with mild OSAS, 34 patients with moderate OSAS and 31 patients with severe OSAS, and the right eyes of 30 patients as a control group. Patients were examined to exclude the possibility of ocular diseases. Cellular density in the cornea epithelium (cell/mm2), corneal thickness (µ), percentage of hexagonal cells (%) and the coefficient of variation were evaluated using a specular microscope. RESULTS: Corneal thickness was significantly decreased in all OSAS groups when compared to the control group (p = 0.002), while no significant difference was identified among the OSAS groups. The corneal endothelial cell density, percentage of hexagonal cells and coefficient of variation were significantly different between the OSAS groups and the control group (p < 0.001). CONCLUSION: More significant impairments were noted in the corneal endothelium of the patients in the OSAS group than in the control group, and specular microscopy is in valuable in the follow-up and treatment of such patients.

OBJECTIVES: This study aimed to evaluate the retinal vasculature of the macula and optic disc in patients with chronic obstructive pulmonary disease (COPD) by optical coherence tomography angiography (OCTA). METHODS: The right eyes of 70 COPD patients and 71 healthy individuals were evaluated. These patients had moderate airflow limitation and mean PO2 of 60 mmHg, and their average age was less than 60 years. Superficial and deep capillary plexus vascular densities, foveal avascular zone (FAZ) width, and optic disc parameters were measured with OCTA. In addition, the correlation between the PO2 level in COPD patients and superficial, deep, and peripapillary vascular densities and FAZ was examined in the study. RESULTS: The COPD group had a significant decrease in the vascular density in the superficial (fovea [p = 0.019]; parafovea [p = 0.013]; and perifovea [p = 0.001]) and deep capillary plexus (fovea [p = 0.028]; parafovea [p = 0.005]; and perifovea [p = 0.002]). Also, the enlargement of the FAZ (p = 0.002) and a decrease in the peripapillary vascular density (p = 0.006) were observed in the COPD group. There was a positive correlation between PO2 level and superficial, deep, and peripapillary vascular densities in COPD patients and a negative correlation with FAZ (r = 0.559-0.900). CONCLUSION: Hypercapnia, respiratory acidosis, and chronic hypoxia associated with COPD may affect the macula and optic nerve, resulting in a serious decrease in vascular density, and OCTA can be a very important tool in the follow-up and treatment of these patients.

PURPOSE: to describe the demographic characteristics and ocular manifestations of patients with late-onset Behçet disease (BD). PATIENTS AND METHODS: The patients for this retrospective study were selected using the data obtained from the medical records of 16 patients with late-onset BD between January 2000 and May 2008. RESULTS: twelve (75%) of the cases were male and 4 (25%) were female. The mean age of patients was 53.8 ± 2.9 years (range, 51-60 years). The mean follow-up period was 4.3 ± 1.1 years (range, 3-8 years). Throughout the follow-up period, panuveitis, posterior uveitis, and anterior uveitis were detected in 11 (68.7%), 4 (25%) and 1 (6.2%) of 16 patients, respectively. CONCLUSION: in our series, the most frequent type of uveitis was panuveitis and male sex seems to be a significant risk factor for developing panuveitis. Late-onset BD showed a marked preponderance of males with a sex ratio of 3:1.

OBJECTIVES: The purpose of the current study was to clinically evaluate the technique of longer pull-out suture as a transmission suture for early active motion after flexor tendon repair in the proximal zone-2. METHOD: Eleven patients (eight adult male, two adult female and one child) with 19 proximal zone II flexor tendon lacerations were included. Mean age was 35 years. The patients were encouraged to perform active mobilization of the injured digits by themselves with full range of flexion from the first postoperative day. The pull-out suture was removed at the 8-10 weeks after the operation. RESULTS: The mean follow-up was 39 months. The procedure was well tolerated by all of the patients. A patient of whom pull-out suture was traumatized and loosened at 6th week showed fair result. Two other patients with a history of blunt trauma were also found to have fair results. Overall 16 of the 19 digits were evaluated as excellent or good by the Strickland criteria. CONCLUSION: The results of this method show that the longer pull-out suture technique as a transmission suture followed by early active mobilization is safe, has a low re-rupture rate and is easy to perform for proximal zone-2 flexor tendon injuries.

Introduction The aim of this study is to evaluate the usefulness of YouTube videos about retinal detachment surgery as a resource. Methods The first 100 videos were evaluated when they were scanned by typing "retinal detachment surgery " in the YouTube search engine. These videos were also analyzed and scored using DISCERN, Journal of the American Medical Association (JAMA), and Global Quality (GQ) scoring systems. Results The DISCERN score of the evaluated videos was 39.5±8.4; JAMA score was 1.9±0.5; and the GQ score was 2.1±0.5. According to the results, retinal detachment surgery videos, DISCERN score is medium; The JAMA score was evaluated as low quality and poor quality in the GQ score. Conclusion Although there are enough videos on YouTube with retinal detachment surgery, its usefulness as a resource is low, and its quality is poor.
RESUMEN
OBJECTIVE: To evaluate the macula and optic disc in varicocele patients with optical coherence tomography angiography (OCTA). METHODS: The right eyes of 30 patients with varicocele and 30 healthy volunteers were evaluated. Superficial and deep capillary plexus vascular densities, foveal avascular zone (FAZ) width, and optic disc parameters were measured with OCTA. RESULTS: There was a significant decrease in vascular density in the superficial and deep capillary plexus in the varicocele group compared to the control group, but no difference was found in FAZ and optic disc parameters. CONCLUSION: Patients with varicocele have reduced microvascular density in the retina; therefore, it may be beneficial to perform a detailed eye examination with OCTA in these patients.
RESUMEN
OBJECTIVE: This study aimed to evaluate ocular vascularity in young adult migraine patients with visual aura and without visual aura. MATERIAL AND METHODS: The study included 30 patients with migraine with visual aura (MWVA), 30 patients with migraine without visual aura (MWOVA), and 30 healthy control subjects, all between ages ≥18 and <45. Migraine patients were applied Headache Impact Test (HIT) and Migraine Disability Assessment Scale (MIDAS). Retinal nerve fiber layer thickness and ocular vascularity of all participants were evaluated with optical coherence tomography (OCT) and OCT angiography (OCTA). RESULTS: The MWVA group had significantly lower superficial and deep foveal vascular density values compared to the control group (p = 0.039, p = 0.028, respectively). The foveal avascular zone was significantly enlarged in the MWVA group compared to the control group (p = 0.033). MWVA patients had significantly lower whole optic disc, optic disc inside, peripapillary, superior hemisphere, inferior hemisphere, superior quadrant, and temporal quadrant vascular density values compared to the control group (p < 0.05 all), while there was no significant difference in the nasal quadrant (p = 0.083). Migraine attack frequency, MIDAS, and HIT were negatively correlated with ocular vascular density values. CONCLUSION: The results of our study indicate that young adult patients with MWVA are at risk of decreased ocular vascularity and that this risk may increase with frequency and severity of migraine attacks.

OBJECTIVE: The objective of this study is to evaluate the corneal endothelium in patients with chronic obstructive pulmonary disease (COPD) using a specular microscope. METHODS: The right eyes of 64 patients with a COPD diagnosis and 65 healthy individuals were evaluated. Cell density (CD) (cell/mm2 ), corneal thickness (CT) (µ), hexagonal cell ratio (%), and coefficient of variation (cell area standard deviation/mean cell area, µm2 ) were analyzed by specular microscopy (SM). RESULTS: The CT was significantly reduced in the COPD group compared with the control group (P = 0.021). Moreover, a significant difference was found between the COPD group and the control group in terms of corneal endothelial CD (P = 0.011), hexagonal cell ratio (P = 0.008), and coefficient of variation (P = 0.012). CONCLUSION: The corneal endothelial structure was significantly deteriorated in patients with COPD compared with the control group. SM is a valuable method that could be used in treatment and follow-up of corneal endothelium in patients with COPD.

BACKGROUND: Our aim was to express the importance of emergency diagnosis and surgical approach in penetrating cardiac trauma patients. METHODS: Kosuyolu Heart and Research Hospital moved to its new location in Cevizli Kartal in June 2005. Due to its close proximity to the main roads of the city, the number of trauma cases has increased tremendously. We have retrospectively examined our penetrating cardiac trauma cases treated between June 2005 and September 2008. RESULTS: Twenty-six trauma cases were admitted to our clinic with penetrating cardiac trauma. Twenty of them were operated on an emergency basis. One (5%) had a gunshot wound while the other 19 (95%) had stab wounds. Four were female (20%) and 16 were male (80%). Average age of the patients was 24.9+/-10.1 (12-49) years. Telecardiography and transthoracic echocardiography were used for diagnosis. Surgical approaches were median sternotomy in 14 and left anterolateral thoracotomy in 6 cases. The right ventricle was damaged in 12, left ventricle in 7 and pulmonary artery in 1. Additionally, 5 patients had lung injury, 1 had brachiocephalic vein injury and 1 had coronary artery injury. One patient was re-explored for bleeding. There were two mortalities (10%) postoperatively. CONCLUSION: Rapid transfer to the emergency department, accurate and quick diagnosis and aggressive surgical approach will increase survival in penetrating cardiac trauma.

OBJECTIVES: Our primary aim was to investigate the association between the preoperative concentration of plasma fibrinogen and the volume of postoperative bleeding. Our secondary aim was to identify whether there is a possible correlation between the patients' different characteristics and haemostatic laboratory variables and the postoperative amount of bleeding after on-pump coronary artery bypass grafting procedures. METHODS: A total of 550 adult patients undergoing isolated coronary artery bypass grafting on cardiopulmonary bypass in our hospital were enrolled and investigated retrospectively. The total amount of chest tube drainage within the first 24 postoperative hours or until the patient was re-explored for bleeding was assessed. Excessive bleeding was defined as more than 500 ml drainage in the first 24 h. The patients were divided into 2 groups: Group 1: the patients who bled ≤500 ml in the first 24 h and Group 2: the patients who bled >500 ml in the first 24 h. RESULTS: A preoperative fibrinogen threshold associated with excessive bleeding was investigated by receiver operating characteristic curve analyses, revealing a calculated cutoff value of 3.1 g/l. Risk factors for increased bleeding were analysed by a logistic regression model that revealed male gender (P < 0.001), body mass index ≤28.3 kg/m2 (P < 0.001), platelet count ≤233 × 103/µl (P < 0.001), estimated glomerular filtration rate ≤90.8 ml/min (P < 0.001) and fibrinogen ≤3.1 g/l (P = 0.01) as significant predictors. CONCLUSIONS: A preoperative plasma fibrinogen concentration <3.1 g/l was associated with increased risk of excessive bleeding in patients undergoing on-pump coronary artery bypass grafting. The amount of postoperative blood loss can be roughly predicted with simple preoperative blood tests.

BACKGROUND/AIM: Anterior cruciate ligament (ACL) deficiency results in several kinematic changes in the lower extremities. The aim of this study is to define the plantar pressure parameters in ACL-deficient patients and to show the effect of ACL reconstruction on dynamic plantar pressure. MATERIALS AND METHODS: Forty patients with unilateral ACL rupture and 40 healthy controls were included in this study. Dynamic plantar pressures of both groups were recorded by the EMED SF-2 system during level walking. Thirteen of the patients who had ACL reconstructions with hamstring autografts (HS group) were reevaluated at an average of 14.5 months following the ACL reconstructions. RESULTS: ACL-deficient patients had significantly lower hindfoot (P = 0.007) but higher midfoot pressure values (P = 0.03) on their ipsilateral foot compared to control group subjects. Ipsilateral hindfoot pressures were also found to be significantly lower than those of the contralateral foot (P = 0.001). Hindfoot pressure values of the HS group were increased in postoperative measurements (P = 0.01). CONCLUSION: ACL-deficient patients have altered plantar pressure distributions and ACL reconstructions restore these changes to normal. Pedobarography might be used as a practical method for dynamic functional assessment of ACL-deficient patients.

BACKGROUND: Delayed union of fractured bone is one of the main problems of orthopedics and traumatology practice. It was hypothesized that the beneficial effects of allogeneic platelet-rich plasma (PRP) would be valuable in the treatment of segmental bone defects. This study is a comparison of the effects of demineralized bone matrix (DBM) and PRP in a segmental bone defect model. METHODS: Total of 48 Wistar albino rats were separated into 4 groups. Segmental bone defect was created at right radius diaphysis in all specimens using dorsal approach. Four additional rats were used as PRP source. Intracardiac blood was withdrawn before the operation for preparation of allogeneic PRP. Group 1 (n=12) served as control group and defects were left untreated. Group 2 (n=12), was PRP group, and received grafting with PRP. Group 3 (n=12) was PRP+DBM combination group, and was treated with grafting and mixture of DBM and PRP. In Group 4 (n=12), defect area was grafted with DBM only. At the end of 10th week, rats were sacrificed, forearms were dissected, and defect areas were examined with radiological and histopathological parameters. RESULTS: Radiological evaluation revealed that ossification was best in PRP group, followed by DBM group. According to results of histopathological studies, union quality was better than control group in all treatment groups (Groups 2, 3, and 4), and was best in PRP group (p<0.05). Results were also better in PRP group when examined in terms of cortex development and remodeling (p<0.05). When examined in terms of new osteogenesis, results were comparable in Groups 2, 3, and 4, but all were better than control group. CONCLUSION: It was concluded that PRP and DBM have comparable effect on recovery of defective bones, but there is no synergistic effect when used together. We believe that PRP can be a cost-effective, readily available alternative to DBM with minimal morbidity.
