Comparison of Radiographic Measurement Parameters of the Wrist in Patients with and without Scaphoid Fracture after Fall on an Outstretched Hand.

PURPOSE OF THE STUDY: To investigate the effects of anatomical variations on the mechanism of scaphoid fracture by comparing the radiologic parameters of the wrist of patients with and without scaphoid fracture after a fall on an outstretched hand. MATERIAL AND METHODS: Cross-sectional comparative retrospective analysis of radiographs of patients with (Group 1, n=169) and without scaphoid fracture (Group 2, n=188). Morphometric data were measured including radial inclination (RI), radial height (RH), ulnar variance (UV), carpal height (CH) ratio, revised carpal height (RCH) ratio and palmar tilt of the distal radius (PT). Receiver operating characteristics (ROC) curve analysis was used to assess the diagnostic performance for each variable with statistically significant difference. RESULTS: The mean RI and PT degrees and RH length were statistically significantly higher, and the mean UV was lower in Group 1 compared to Group 2. No difference was determined between the groups with respect to the CH ratio and RCH ratio. With ROC curve analysis, the cut-off value with the highest odds ratio was determined as RH (Cut-off value=10.77 mm, OR=21.886). CONCLUSIONS: Although higher RI, RH, PT values and more negative ulnar variance were observed in the scaphoid fracture group compared to the non-fracture group, ROC curve analysis showed that only increased RH can be considered as a possible risk factor for scaphoid fractures after fall on an outstretched hand. KEY WORDS: radiographs, risk factor, scaphoid fracture, wrist morphology.

The Relationship Between Controlling Nutritional Assessment Score and Mortality in Patients with Chronic Coronary Syndrome: A Retrospective Study from Türkiye.

BACKGROUND: Controlling Nutritional Assessment (CONUT) score has been shown to have a higher predictive value compared to other nutritional scores in acute coronary syndrome. AIM: To determine the relationship between CONUT score and long-term mortality in patients with chronic coronary syndrome (CCS). METHODS: Between 2017 and 2020, 585 consecutive patients newly diagnosed and proven to have CCS by coronary angiography were included in the study. CONUT score and demographic and laboratory data of all patients were evaluated. The relationship between results and mortality was evaluated. RESULTS: The mean age of the patients was 64 years and 75% were male. Mortality was observed in 56 (9.6%) patients after a median follow-up period of 3.5 years. The median CONUT score was significantly higher in patients with mortality (P < 0.001). In multivariate regression analysis, the CONUT score was associated with mortality (Hazard ratio (HR): 1.63 (95% confidence interval (CI): 1.34-1.98 P < 0.001)). The area under curve (AUC) for long-term mortality estimation for the CONUT score was 0.75 (95% CI 0.67-0.82 P < 0.001). When the CONUT score value was accepted as 0.5, the sensitivity was 78% and the specificity was 60. CONCLUSION: CONUT score was found to be predictive of mortality in long-term follow-up of patients with CCS.

Radial shortening osteotomy vs partial capitate shortening osteotomy in Kienböck's disease: Medium-term radiological and clinical results.

This study aimed to compare medium-term results for partial capitate shortening (PCS) and radial shortening (RS) osteotomies on lunate bone revascularization and disease progression in patients with stage II or IIIA Kienböck's disease. Patients who underwent surgery for Kienböck's disease between March 2010 and July 2020 were retrospectively evaluated. Clinical evaluation included assessment of pain, joint range of motion, strength, DASH, visual analog scale (VAS) for pain, Modified Mayo Wrist Score (MMWS), satisfaction and time to return to work, with comparison as appropriate to the contralateral side. Preoperative and postoperative plain radiographs and magnetic resonance imaging (MRI) were used for radiological evaluation. Lichtman staging and signal changes in the lunate were evaluated using MRI. Group 1 (PCS) included 14 patients and Group 2 (RS) 14. Mean follow-up was 57.8 months (range 24-102) in Group 1 and 49.4 months (range 36-73) in Group 2. Clinical evaluation included pain on VAS, DASH score, MMWS, range of motion, and grip, palmar and key pinch strength. Regarding lunate bone vascularization, increased signal on final follow-up MRI was observed in 10 of the 14 patients in Group 1 and 7 of the 14 patients in Group 2. There was a positive correlation between revascularization and final follow-up MMWS (p = 0.006). The present study thus showed that functional scores were improved by revascularization in Kienböck's disease. Both osteotomies had clinically and radiologically satisfactory results. However, we believe that PCS osteotomy is preferable, as it leads to higher revascularization rates without increasing ulnolunate load.

Are radiological measurements reliable methods in the postoperative follow-up of calcaneal fractures?

BACKGROUND: Böhler's angle (BA) and the crucial angle of Gissane (CAG) are the most frequently used objective measurements for the follow-up of fixation following calcaneus fracture surgery. However, the measurements of these angles by different people can affect the results and cause conflicting interpretations of different results obtained. This has caused confusion in the literature. AIMS: The aim of this study was to investigate the reliability and disagreement of BA and the CAG, and to interrogate the veracity of angular changes in the postoperative period of calcaneal fractures. METHODS: In the first round, a total of 82 postoperative lateral radiographs were investigated to assess the inter-tester reliability and disagreement. Second round; all radiographs were re-evaluated by two testers 15 days after the first measurement. These values were used to assess the intra and inter-tester reliability, disagreement and false negative/positive angular change. All measurements were performed separately by a radiologist and an orthopedic surgeon. RESULTS: Inter- and intra-tester reliability was found low to high in BA (ICC: 0.465 to 0.837), and moderate to very high in CAG (ICC: 0.661 to 0.926). The mean inter-tester disagreement of BA was 4.19° and 6.07°. These values were 4.76° and 7.22° for CAG. The mean intra-tester disagreement of BA was 4.09° for the orthopedic surgeon and 3.97° for the radiologist. These values were 4.96° and 4.39° for CAG respectively. The false negative angular difference was found for BA in 51 (62.2%) cases for the orthopedic surgeon and 46 (56.1%) cases for the radiologist. The mean values were -3.87° and -4.21°, respectively. For the CAG, the false positive angular difference was found in 43 (52.4%) cases for both the orthopedic surgeon and the radiologist. The mean values were +5.01° and +4.72°, respectively. CONCLUSION: These angles alone should not be considered to be of guidance in the postoperative period. If any angular change is determined on the lateral radiographs, this could arise from a disagreement or false angular change.

Tenolysis rate after zone 2 flexor tendon repairs.

OBJECTIVES: This study aims to evaluate the tenolysis rates of zone 2 flexor digitorum profundus (FDP) with flexor digitorum superficialis (FDS) tendon repairs using four-strand technique and early passive motion exercises. PATIENTS AND METHODS: In this retrospective study, we performed zone 2 flexor tendon repairs in 149 patients (117 males, 32 females, mean age 33.3±12.9 years; range, 13 to 72 years) (82 right and 67 left hands) between November 2014 and January 2019. A total of 194 FDP and FDS tendons were repaired primarily by using modified Kessler and Bunnell methods. Patients underwent pure passive motion protocols after surgery according to modified Duran's protocol. No active flexion components were added until postoperative fourth week. RESULTS: Twenty-three out of 149 patients and 28 out of 194 fingers (14.43%) had tenolysis. There was no significant relationship between the number of operated fingers, gender, and tenolysis rate (p=0.836, p=0.584, respectively). CONCLUSION: The repair of the FDP with FDS tendon increases the tenolysis rate in zone 2. The tenolysis rate does not change according to the number or distribution of injured fingers and gender of the patient.

Anatomic variations associated with antrochoanal polyps.

OBJECTIVE: Although more than a century has passed since antrochoanal polyps (ACPs) were first defined, etiopathogenesis still remains unclear. The aim of this study was to investigate the relationship between ACPs and sinonasal cavity variations. SUBJECTS AND METHODS: One hundred and forty-four patients with ACP on paranasal sinus computed tomography scans (ACP group) and 160 paranasal sinuses without ACP (control group) were included into the study. The study group was evaluated in respect of the presence of retention cyst in the contralateral maxillary sinus and sinus bone wall sclerosis thickening. Both groups were also compared with respect to the frequency of sinonasal anatomic variations, nasal septal deviation, variations of the uncinate process insertion, concha bullosa, paradoxical middle turbinate, and accessory maxillary sinus ostium. In the ACP group, the cases with septal deviation (SD) were also evaluated whether the deviation convexity was towards the polyp side or the opposite side. In addition, the posterior extension of ACPs were evaluated in three groups as middle meatus, nasopharynx, and oropharynx extension. RESULTS: The prevalence of retention cyst, sinus wall sclerosis thickening, SD, and accessory maxillary ostium was significantly higher in the ACP group. A negative directional correlation was determined between the SD side and ACP side. When the ACP extensions were examined, middle meatus extension was seen in 32.6%, nasopharynx in 56.3%, and oropharynx in 11.1%. CONCLUSION: Accessory ostium may be an accelerating factor in the transformation of retention cyst to ACP. Furthermore, the changes in the nasal passage airflow on the opposite side suggest that SD contributes to this process.

Periodontal education and assessment in the undergraduate dental curriculum-A questionnaire-based survey in European countries.

OBJECTIVES: This survey aimed to evaluate whether periodontal education and assessment in undergraduate dental curricula amongst the member countries of the European Federation of Periodontology (EFP) follow the competency-based curricular guidelines and recommendations developed by the Association for Dental Education in Europe. MATERIALS AND METHODS: A multiple-choice questionnaire was emailed to 244 dental institutes amongst the 24 EFP member countries between November 2014 and July 2015. RESULTS: Data were received from 16 (66.7%) EFP member countries. Out of 117 responding dental institutes, 76 (64.95%) were included as valid responders. In most of the institutes (86.3%), a minimum set of competencies in periodontology was taken into account when constructing their dental education programmes. Out of 76 responders, 98.1% included lecture-based, 74.1% case-based and 57.1% problem-based teaching in their periodontal curricula, whilst a minority (15.9%) also used other methods. A similar pattern was also seen in the time allocation for these four educational methods, that is, the highest proportion (51.8%) was dedicated to lecture-based teaching and only a small proportion (5.7%) to other methods. Periodontal competencies and skills were most frequently assessed by clinical grading on clinic, multiple-choice examination (written examination) and oral examination, whereas competency tests and self-assessment were rarely used. Only in 11 (14.5%) cases, access flap procedures were performed by students. CONCLUSION: Great diversity in teaching methodology amongst the surveyed schools was demonstrated, and thus, to harmonise undergraduate periodontal education and assessment across Europe, a minimum set of recommendations could be developed and disseminated by the EFP.

Association between BNP levels and new-onset atrial fibrillation : A propensity score approach.

BACKGROUND: New-onset atrial fibrillation (NOAF), a common complication of acute ST-segment elevation myocardial infarction (STEMI), is associated with a poor prognosis. Several clinical and laboratory parameters are reported to be associated with NOAF in patients with STEMI. The aim of the present study was to evaluate the predictive value of plasma B­type natriuretic peptide (BNP) levels for NOAF development and long-term prognosis in STEMI patients undergoing primary percutaneous coronary intervention (pPCI). PATIENTS AND METHODS: We retrospectively enrolled 1,928 patients with STEMI who underwent pPCI. After applying exclusion criteria, 1,057 patients were retained in the final study population. Patients with NOAF were compared with patients without NOAF in the entire study population and in a matched group. RESULTS: Patients with NOAF had a significantly higher average plasma BNP level (161 pg/ml, range: 72.3-432) than patients without NOAF in the study population (70.7 pg/ml, range: 70-129; p < 0.001) and in the matched group (104.6 pg/ml, range: 47.2-234.5; p = 0.014). Furthermore, the plasma BNP level was found to be an independent predictor of NOAF development (odds ratio [OR]: 1.003; 95% confidence interval [CI]: 1.000-1.005; p = 0.034) and mortality in the long-term follow-up (OR: 1.004; 95% CI: 1.002-1.006; p < 0.001). CONCLUSION: The present study found that a high plasma BNP level was significantly associated with NOAF development in STEMI patients, and was an independent predictor of NOAF development and all-cause mortality during long-term follow-up, regardless of other NOAF risk factors.

Role of anticardiolipin antibodies in the pathogenesis of prosthetic valve thrombosis: An observational study.

BACKGROUND: Prosthetic valve thrombosis (PVT) is serious complication of valvular replacement surgery, and increased levels of anticardiolipin antibodies (aCL) are associated with thrombosis. The aim of this study was to evaluate the role of aCL in the development of PVT. PATIENTS AND METHODS: We studied the aCL IgM and IgG levels in 114 patients with PVT and 80 healthy patients with prosthetic valves without PVT or a history of thrombosis. All patients underwent detailed transthoracic, transesophageal echocardiographic and clinical examinations. Blood samples were obtained after transesophageal echocardiography. Tests were repeated 12 weeks apart in patients with aCL IgM or IgG positivity. RESULTS: The mean age, sex, presence of atrial fibrillation and cardiovascular risk factors, elapsed time after surgery, and prosthetic valve type and location were similar between patients with PVT and those without. Ineffective anticoagulation was significantly higher among patients with PVT (p < 0.001). The aCL IgM values were significantly higher and positive (> 40 MPL) in the PVT group compared with the control group (10.58 ± 15.90 MPL to 3.70 ± 2.30 MPL, p < 0.001; 7.0 to 0 %, p = 0.016, respectively). The aCL IgG values were significantly higher and positive (> 40 GPL) in the PVT group compared with the control group (12.04 ± 17.58 GPL to 3.83 ± 2.56 GPL, p < 0.001 and 7.9 to 0 %, p = 0.01, respectively). According to international consensus documents, 16 patients had antiphospholipid syndrome. Ineffective anticoagulation and aCL IgM and IgG positivity were independent predictors of PVT in logistic regression analysis (multivariate r(2)= 0.648; p < 0.001, OR= 21.405, 95 %CI= 8.201-55.872; p = 0.008, OR= 1.322, % 95CI= 1.076-1.626; p = 0.005, OR= 1.288, 95 %CI= 1.079-1.538). CONCLUSION: Since the presence of aCL IgM and IgG positivity may cause a tendency toward PVT, these values should be examined in all patients with PVT.

Neutrophil-lymphocyte ratio may predict in-hospital mortality in patients with acute type A aortic dissection.

INTRODUCTION: Inflammation has been reported to be associated with aortic dissection (AD), from the development to the prognosis of AD. In this study we aimed to find the role of the neutrophil-lymphocyte ratio (NLR) in the prediction of clinical events in patients with acute AD type A. PATIENTS AND METHODS: The study comprised 37 patients who were hospitalized at our center between 2009 and 2013 with the diagnosis of acute AD type A. RESULTS: The mean NLR was significantly higher in patients with pericardial effusion than those without effusion (15.6 ± 11.4 vs. 7.5 ± 4.8, p = 0.005). An NLR value > 8.51 yielded an area under the curve (AUC) value of 0.829 [95 % confidence interval (CI) 0.674-0.984, p = 0.004], which demonstrated a sensitivity of 77 % and specificity of 74 % for the prediction of mortality. CONCLUSIONS: The novel inflammatory marker NLR could be used to predict pericardial effusion and in-hospital mortality in patients with acute AD type A.

Potential inherited causes of recurrent prosthetic mitral valve thrombosis in a pregnant patient suffering from recurrent miscarriage.

An effective anticoagulation is critical in pregnant patients with prosthetic heart valves. Inherited disorders may interfere with the coagulation cascade and may be associated with obstetrical complications as well as with prosthetic valve-derived complications. The patient in the present case had a history of recurrent prosthetic heart valve thrombosis (PHVT) despite an effective anticoagulation. She underwent a thrombolysis with low-dose prolonged infusion of tissue-type plasminogen activator for the management of her recurrrent prosthetic valve thrombosis. The genetic testing showed homozygous mutations of methylenetetrahydrofolate reductase (MTHFR) A 1298 C and heterozygous mutations of ß-fibrinogen 455 G-A. Inherited disorders such as MTHFR A 1298 C and fibrinogen 455G/A polymorphisms may be involved in the pathogenesis of recurrent PHVT and/or pregnancy loss.

Three-dimensional transesophageal echocardiographic evaluation of cor triatriatum in adults.

We present the cases of two adult patients with cor triatriatum due to left atrial membrane with atrioventricular septal defect and right atrial membrane. Two-dimensional and real-time three-dimensional transthoracic echocardiography were performed. These noninvasive modalities provided a comprehensive anatomic and hemodynamic evaluation of the anomaly.

Delineation of an octopus-like thrombus attached to the eustachian valve.

Eustachian valve (EV) is a vestige of the valve of the inferior vena cava which directs the umbilical vein blood through open foramen ovale in fetal life. Following birth it gradually regresses, but it may persist in variable size, shape, and thickness as a functionless and benign structure. However, there are reports suggesting that persistent EV may not be completely innocent. It has been accused of being a predisposing cause of patent foramen ovale and paradoxical embolism and also interfering with transseptal interventional procedures. It may serve as a site of infective vegetations and be mistaken as a tumor or thrombus. In the present case, an octopus-like thrombus attached to the EV was delineated with the utility of two-dimensional and real time three-dimensional transesophageal echocardiography. EV was considered to play an essential role in preventing potential pulmonary embolism.

Agronomic importance of first development of chickpea (Cicer arietinum L.) under semi-arid conditions: II. Seed imbibition.

Due to the slowness growth and weakness of the first developments of chickpea (Cicer arietinum L.), it could not combated with weeds and easily caught up by Ascochyta blight (Ascochyta rabiei (Pass) Labr.) disease. Additionally, due to biotic and abiotic stress factors, esp. at the late sowing, important seed yield losses could be happened. To be able to avoid from them is only possible to accelerate of its first development as possible as. So, one of the best solutions to is to use chemical compounds such as Humic Acid (HA) known soil regulator under the semi-arid conditions. With this aim this research was performed in a Randomized Complete Block Design (RCBD) with four replications under semi-arid field conditions during (2008/2009) and (2009/2010) in Turkiye. Two cultivars (V1 = Gokce and V2 = Ispanyol) and four seed imbibition methods (A0 = 0, A1 = Tap Water, A2 = 1/2 Tap Water + 1/2 Humic acid (HA), A3 = Full HA, as w/w) and seven yield components Plant Height (PH), Number of Branches per Plant (NBP), Number of Pods per Plant (NPP), First Pod Height (NFP), Number of Seeds per Pod (NSP), Seed Weight per Plant (SWP) and 100-Seed weight (HSW) were investigated. The PH and FPH were affected the A0, the NBP, NPP and NSP were affected the A2 and the SWP and HSW were given the varied but not clear responses according to varieties for all the parameters in A1. The A0 and A1 were encouraged the germination and top soil of the plant but, the A2 to A3 were encouraged root system's development. It was concluded that the A2 is a promising method which makes the maximum and positive effect to the first development of the chickpea agronomy under the semi-arid conditions.
