Background: Literature provides little and controversial evidence regarding the influence of ulnar variance (UV) on the incidence of scaphoid fractures. The aim of this retrospective study was to assess UV in a large number of patients with acute scaphoid fracture in comparison to a control group of the same population. Methods: During a two year period, 182 patients with acute scaphoid fractures (fracture group) and 182 ethnicity-, gender- and age-matched patients with wrist contusions (control group) were treated in three non-university hospitals. Using standardized digital wrist radiographs, UV values were measured by means of the method of perpendiculars by two independent examiners. The UV values of the fracture group were then compared to the UV values of the control group. Results: Analyses of the agreement between the two raters resulted in a good to excellent inter-item correlation of 0.89, with a high intra-class coefficient of 0.93 (95% confidence interval: 0.87–0.95). Mean (SD) UV value was -0.82 mm (1.77) in the fracture group and 0.27 mm (1.44) in the control group. Paired sample t-test showed a significant difference between the two groups (p < 0.0001). Conclusions: According to this study, patients with scaphoid fractures are significantly more likely to show a negative UV than matched patients with wrist contusions.

The Mean

Between 1997 and 2006, radiographs of 66 scaphoid fractures were retrospectively reviewed to evaluate ulnar variance. Twenty-one (31.8%) patients had an ‘ulna neutral’ wrist, six (9.1%) had an ‘ulna plus’ and 39 (59.1%) had an ‘ulna minus’ wrist. The mean ulnar variance was −1.3 (SD 1.8) mm (range −5.5, 2.5). We observed a significant difference in the distribution of ulnar variance ( P < 0.00001) and in the proportion of cases with ulna minus (OR = 5.0; 95% CI: 2.7, 9.3) compared to previous publications.

Objective Plasma is formed by creating a high-density energy field within an electrically conductive fluid such as saline. Sometimes ablated bits of tissue get stuck between the electrodes of the wand, obstructing the suction channel. The purpose of this study is to investigate the effect of cooling the irrigating saline during ablation of the hypertrophied tongue base in patients with obstructive sleep apnea. Study Design Prospective randomized controlled trial. Setting An otorhinolaryngology department in Main University hospitals. Methods Sixty adult patients with obstructive sleep apnea and tongue base hypertrophy underwent tongue base ablation surgery. Patients were randomly divided into 2 groups of 30 patients each: cooled saline and room temperature saline. The Coblation wand used was the EVac 70 Xtra HP (Smith & Nephew). Results In this study, a significant difference in operative time (mean ± SD) was seen between groups: 21.2 ± 5.5 minutes in the cold group and 47 ± 9.5 minutes in the control group ( P = .001). The wands in the cold group did not obstruct, while all the wands in the control group were obstructed by tissue clogs with variable degrees, hence wasting more time to clean the wands’ tips. Conclusion Cooling the irrigating saline overcame the problem of wand clogs, and the wand tip did not occlude at all during the procedures, thus saving time lost in wand cleaning and demonstrating a faster and safer surgical procedure. Further studies are needed to identify the hemostatic effect of the cooled saline over the regular one.

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.

Background: Dyslipidemia is a metabolic disorder that results from imbalanced and overfeeding as well as sedentary life. Elevated blood lipid levels can affect cochlear blood flow and fluidity, leading to decreased hearing and tinnitus. We aimed to determine whether there is a relationship between tinnitus and dyslipidemia by investigating the blood lipoprotein values of patients with tinnitus.Methods: The lipid profiles of the patients with idiopathic tinnitus who were selected among the patients who applied to Istanbul Haydarpaşa Numune Training and Research Hospital with the complaint of tinnitus between January 2019 and May 2020 were examined. The test results and age and gender distributions were compared with control groups without tinnitus complaints and statistical evaluation was performed.Results: Hypercholesterolemia in 42% of 6472 patients with idiopathic tinnitus, 18% low HDL, 50% high LDL, Hyperlipidemia was detected in 21%. 1942 (30%) of these patients were male; 4530 (70%) are women. The number of patients in the control group without tinnitus was 6470. Hypercholesterolemia in 49% of this group; 21% low HDL, 42% high LDL, 16% hyperlipidemia was detected. In this control group, 1950 (30%) of the patients were male and 4520 (70%) were female. Cholesterol of male and female patients with tinnutus. When the cholesterol, LDL and triglyceride values of HDL and LDL values and female and male patients in the control group were examined, a statistically significant difference was found (p <0.005). No statistically significant difference was found between HDL values of female and male patients with tinnutus and HDL values of female and male patients in the control group (P> 0.05).Conclusions: There is a statistically relationship between tinnitus and dyslipidemia. The presence of dyslipidemia is vital due to atherosclerosis caused by dyslipidemia, especially coronary artery involvement. Therefore, dyslipidemia should be treated as it causes many diseases.

Purpose: This study aimed to compare the neutrophil-to-lymphocyte (NLR) and plateletto- lymphocyte (PLR) ratios in patients with retinal artery occlusion (RAO) with those from a healthy control population and to identify the relationship between them. Methods: Forty-six patients with RAO and fifty-one healthy control subjects were included in this retrospective case-control study. RAO was diagnosed following an ophthalmic examination and fluorescein angiography (FA). Blood neutrophil, lymphocyte, and platelet counts were recorded for each of the 97 subjects, from which NLR and PLR values were calculated. Results: There were 46 patients (28 male [M], 18 female [F]) in the RAO group and 51 patients (27 M, 24 F) in the control group. No significant differences were found between patients with RAO and the control subjects in terms of gender and age (P > 0.05). Patients with RAO had significantly increased NLR values (2.85 ± 1.70) than the control subjects (1.63 ± 0.59, P < 0.001). The mean PLR in patients with RAO was 123.69 ± 64.98, while that in control subjects was 103.08 ± 36.95; there was no significant difference between the two groups (P = 0.055). A logistic regression analysis revealed that NLRs were 3.8 times higher in patients with RAO than in control subjects (odds ratio = 3.880; 95% confidence interval = 1.94 to 7.74; P < 0.001). Conclusion: NLRs were significantly increased in patients with RAO compared to the control subjects.

Introduction It has been estimated that between 15% and 18% of patients who start antiretroviral therapy (ART) do not achieve a successful immune recovery despite complete virological suppression. In the literature this phenomenom is known as poor immune recovery or immunovirological discordance (IVD). Zinc has an immunomodulatory role associated with T lymphocytes and its supplementation could enhance immune recovery. Objective To determine if zinc supplementation on IVD patients prevents immune failure after 12 months of supplementation. Secondary objectives were to determine serum zinc levels in HIV patients with and without IVD and the frequency of hypozincemia in discordant patients. Method We reviewed the historical record of patients under care at Arriarán Foundation. Following inclusion criteria were defined: 1) age ≥ 18 years, 2) standard ART (three effective drugs) for at least 18 months, 3) virologically suppressed for 12 months, 3) persistence of CD4 count ≤200 cells/mm3 and/or increase ≤ 80 cells/mm3 after one year of viral undetectability. A control group was assigned paired 1:1 by sex, age (± 2 years) that did achieved an increase of CD4> 350 cells/ mm3. In both groups plasma zinc levels were determined. In a later phase, patients with IVD were randomized to receive zinc (15 mg daily) versus placebo. Patients were followed for 12 months with CD4 count, viral load and zinc levels determinations every 4–6 months. Results A total of 80 patients, 40 patients with IVD criteria and 40 controls were included. 92.5% were men, and age average was 47.5 years. The median baseline CD4 was 189 cells/mm3 (71–258) in the cases vs. 552.5 cells/ mm3 (317–400) in the control group with a median increase at the end of the study of 39 cell/mm3 and 19 cell/mm3 respectively. There was no difference in baseline plasma zinc levels between both groups (81.7 + 18.1 in cases versus 86.2 + 11.0 in controls). In the 40 patients with IVD, the median absolute increase in CD4 after annual zinc supplementation was 31.5 cells/mm3 in the treated group versus 50 cells/mm3 in the placebo group, this difference being statistically not significant (p = 0.382). Conclusions Patients with IVD have plasma zinc levels similar to those who achieve adequate immune recovery. Zinc supplementation in IVD patients showed a statistically non-significant difference in in CD4 levels between cases and controls. The results warrant a comparative study with a larger number of patients.

Abstract Purpose: In our study, we aimed to determine the frequency of thyroid nodules in patients with acromegaly according to the American College of Radiology (ACR) Thyroid Imaging, Reporting and Data System (TI-RADS) classification and its relationship with acromegaly disease activity. Methods: A total of 56 patients with acromegaly and age, sex, and body mass index matched with 56 healthy control subjects were included in our study. Thyroid-stimulating hormone, free thyroxine, and anti-thyroperoxidase antibody levels of patients and control subjects were measured. In addition, patients and healthy controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules and to make ACR TI-RADS classification. Results: Thyroid nodules were present in 31 (55.4%) of 56 patients in the acromegaly group and 20 (35.7%) of 56 subjects in the control group, and the frequency of thyroid nodules was significantly higher in the acromegaly group (p=0.038). The mean number of nodules in the acromegaly group and control group was 1.27±1.43 and 0.48±0.73, respectively, and the mean number of nodules was significantly higher in the acromegaly group (p=0.003). The number of patients with TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules in the acromegaly group was higher than the control group (p=0.026, p=0.049, p=0.007, respectively). No difference was found in terms of cytological findings between those who have undergone FNAB in the acromegaly group and control group. Conclusion: In our study, we found that the frequency of thyroid nodules, the number of thyroid nodules, and the number of TI-RADS 1, TI-RADS 2, and TI-RADS 4 nodules increased in patients with acromegaly. There was no significant difference between acromegaly disease activity and thyroid nodule frequency, number of thyroid nodules, and TI-RADS classifications.

Category: Ankle Introduction/Purpose: Syndesmotic lesions of the ankle have shown to be challenging injuries towards diagnosis and surgical treatment. This could be mainly attributed to the limitations of 2D imaging, which make it difficult to accurately determine the extent of the lesion and to verify if peroperatively an anatomical reduction is achieved of the distal tibiofibular congruence. The aim of this study is therefore to develop a reproducible method to quantify the displacement in a syndesmotic ankle lesion in all six degrees of freedom based on 3D imaging. Methods: Eighteen patients were retrospectively included having a unilateral syndesmotic lesion. N=12 sustained a high ankle sprain and a bilateral weightbearing conebeam CT was obtained because of positive clinical syndesmotic tests. N=6 presented with a fracture associated syndesmotic lesion and were imaged by a bilateral non-weightbearing CT. The non-affected ankle was used as a template after being mirrored and matched on the contralateral ankle containing a syndesmotic lesion (Fig 1A-B). The distal fibula was marked by computer calculation of the most outer point of the anterior tubercle, posterior tubercle and apex malleolis lateralis. The change of these points towards the unaffected fibular position was used to quantify the syndesmotic lesion (Fig 1C). A control group of seven patients (N=7) was used to analyse if these changes differed from the normal variation in tibio-fibular congruency (Fig 1D). Results: The main findings consisted of a statistical significant difference in the mean mediolateral diastasis of both the sprained group (M = 1.60 mm, SD=1.02) and the fracture group (M = 1.69 mm, SD=0.62) compared to the control group (P<.001). The mean external rotation was statistically different when comparing the sprained group (M = 4.68°, SD=2.74) and the fracture group (M = 6.97°, SD=3.02) towards the control group (P<.05). The mean antero-posterior translation was only significantly different when comparing the fracture group (M = -4.73 mm, SD=4.53) towards the sprained group (M = -0.91 mm, SD=1.26) and the control group (M = -0.26 mm, SD=1.53) (P<.05). Conclusion: This study demonstrates an effective method to quantify a unilateral syndesmotic lesion of the ankle. The pathological measurements differed from the normal distal tibio-fibular configuration in the syndesmotic complex. This sequential analysis is of use for an accurate diagnosis and a pre-operative planning to know in advance which correction needs to be achieved to have the fibula at proper length correctly rotated, and reduced into the syndesmosis with no anterior, posterior or lateral displacement.

Background and objectives: Anticoagulants are thought to increase the risks of traumatic intracranial injury and poor clinical outcomes after blunt head trauma. The safety of using direct oral anticoagulants (DOACs) compared to vitamin K antagonists (VKAs) after intracranial hemorrhage (ICH) is unclear. This study aims to compare the incidence of post-traumatic ICH following mild head injury (MHI) and to assess the need for surgery, mortality rates, emergency department (ED) revisit rates, and the volume of ICH. Materials and Methods: This is a retrospective, single-center observational study on all patients admitted to our emergency department for mild head trauma from 1 January 2016, to 31 December 2018. We enrolled 234 anticoagulated patients, of which 156 were on VKAs and 78 on DOACs. Patients underwent computed tomography (CT) scans on arrival (T0) and after 24 h (T24). The control group consisted of patients not taking anticoagulants, had no clotting disorders, and who reported an MHI in the same period. About 54% in the control group had CTs performed. Results: The anticoagulated groups were comparable in baseline parameters. Patients on VKA developed ICH more frequently than patients on DOACs and the control group at 17%, 5.13%, and 7.5%, respectively. No significant difference between the two groups was noted in terms of surgery, intrahospital mortality rates, ED revisit rates, and the volume of ICH. Conclusions: Patients with mild head trauma on DOAC therapy had a similar prevalence of ICH to that of the control group. Meanwhile, patients on VKA therapy had about twice the ICH prevalence than that on the control group or patients on DOAC, which remained after correcting for age. No significant difference in the need for surgery was determined; however, this result must take into account the very small number of patients needing surgery.
