Purpose: Despite being repeatedly shown that exercise training (ET) increases exercise capacity and decreases mortality in many cardiac conditions, not all patients enjoy the benefits of ET programs. We hypothesized that baseline cardiovascular mechanic properties, including cardiac systolic and diastolic functions, arterial mechanics and ventriculoarterial interaction, may have a role in predicting response to ET. Methods: Full left ventricular pressure-volume loops were constructed and arterial mechanics were evaluated using echocardiographic and tonometric measurements. A cardiopulmonary exercise (CPX) test was performed before a . . .nd after the ET program. Result: Sixty of the 75 patients with coronary artery disease or heart failure diagnoses completed the study. All of the CPX parameters showed a significant improvement with ET. The change in oxygen uptake correlated only with arterial parameters, such as compliance (r=0.399, P=.002), end-systolic arterial elastance (r=- 0.293, P=.02), aortic pulse pressure (r=- 0.302, P=.02), and brachial pulse pressure (r=- 0.312, P=.01). Receiver-operating characteristics analysis demonstrated that baseline arterial compliance and brachial pulse pressure predicted a significantly positive ET result with reasonable sensitivity and specificity. Conclusions: Patients with a more compliant arterial system improved their exercise capacity more with ET. Evaluation of baseline arterial compliance may facilitate proper patient selection and may define patients who need optimizing measures for the arterial system before commencing ET. Even a simple blood pressure measurement may give clues in this regard. © Copyright 2016 Wolters Kluwer Health Daha fazlası Daha az

Uzun, S. | Aciksoz, S. | Arslan, F. | Yildiz, C. | Akyol, M.

Article | 2016 | Orthopaedic Nursing35 ( 2 ) , pp.120 - 125

Subcutaneous heparin administration is routinely used for many patients in orthopaedic clinics. Nurses frequently encounter ecchymosis formation with heparin administration. Previous research indicates that the administration protocol may have effect on ecchymosis formation. The study was performed to determine and compare the effect of three different approaches of subcutaneous enoxaparin injection on ecchymosis formation in patients who underwent joint replacement surgery. Three protocols were compared: (1) injecting enoxaparin in 10 seconds, (2) injecting enoxaparin in 30 seconds, and (3) injecting enoxaparin in 30 seconds and wa . . .iting for an additional 10 seconds before withdrawing the needle. Ecchymosis formation was assessed in both size and frequency. Descriptive statistics, Kruskal-Wallis analysis, Mann-Whitney U test, and Spearman rank correlation test were used to assess the data. The ecchymosis frequency was higher in the 10-second administration. Ecchymosis size was smaller when the enoxaparin was administered in 30 seconds and the needle was kept in the tissue for 10 seconds after injection. The enoxaparin should be administered in a longer duration (30 seconds). Keeping the needle in the tissue for 10 seconds may further decrease the size but not the incidence of ecchymosis Daha fazlası Daha az

Kamaci, S. | Yucekul, A. | Demirkiran, G. | Berktas, M. | Yazici, M.

Article | 2015 | Spine40 ( 13 ) , pp.120 - 125

Study Design. This is a cross-sectional descriptive study. Objective. The purposes of this study are to describe normative data of the sagittal plane in the sitting position within the pediatric population and document the evolution of sagittal alignment during the growth. Summary of Background Data. Surgical procedures addressing the deformity aim to make the maximal correction on the coronal and transverse planes and to restore the physiological curves on the sagittal plane. Prerequisite for sagittal plane reconstruction is to know the physiological values. Methods. Children between 3 and 17 years of age, followed by pediatrics un . . .it for nonskeleton disease with lateral radiographs of the entire spine and pelvis on sitting positions, were included to the study. Children with history of surgery or disease that may affect spine development were excluded. Children were evaluated in 4 age groups (3-6, 7-9, 10-12, and 13-17 yr) in terms of spinal sagittal alignment on sitting position. Results. Of the screened, 124 children (49 girls, 75 boys) were included. Descriptive statistics of all possible segmental angles were summarized. Thoracic kyphosis and lumbar lordosis values were lower on sitting position than on standing position. Thoracic segmental angulations steadily increased from T1-T2 to midthoracic segments and then decreased in caudal direction. Moreover, lumbar segmental angulations steadily increased in cephalocaudal direction. Sacral slope, L4-S1 angulation, and T1-T12 and T1-S1 distance tend to increase as the age increases. Conclusion. Sagittal spinal alignment in the sitting position is different than that in the standing position and it changes as the child grows. There is a statistically significant difference between different age groups, especially at the cervicothoracic, thoracolumbar, and lumbosacral junctions. These findings should be taken into consideration for young nonambulatory patients who require spinal instrumentation and/or fusion. © 2015, Wolters Kluwer Health, Inc.

Yilmazer, R. | Gerring, R.C. | Sidani, C. | Wolfovitz, A. | Angeli, S.I. | Telischi, F.F.

Article | 2018 | Otology and Neurotology39 ( 7 ) , pp.120 - 125

Hypothesis: The retrofacial approach is a feasible approach to the round window niche and that the Round window-Sigmoid sinus line will help determine the feasibility of retrofacial approach for cochlear implantation unless there is a very high jugular bulb. Background: When the round window cannot be visualized by facial recess approach during cochlear implantation, other conservative techniques can be used to improve visualization such as the retrofacial approach. Methods: Thirteen adult dry cadaveric temporal bones were studied. Computed tomography (CT) scan was obtained on all temporal bones. An imaginary Round window-Sigmoid si . . .nus line was drawn on the axial images. We assessed whether this line is anterior (including intersection) or posterior to the facial nerve (FN). The following closest distances were measured on CT scans: 1) posterior semicircular canal (PSC)-FN, 2) PSC-Stapedius muscle, 3) PSC-Jugular bulb, 4) lateral semicircular canal (LSC)-Jugular bulb, 5) sigmoid sinus-FN. A canal wall-up mastoidectomy, facial recess, and retrofacial approach were performed in all specimens. We have noted whether we need a standard or an extended mastoidectomy. Results: The Round window-Sigmoid sinus line was posterior to the FN in all specimens. The retrofacial approach was feasible and the round window was visualized in all specimens. Extended mastoidectomy was required in seven specimens and the PSC-FN was ? 3 mm in five of them. Conclusion: Retrofacial approach is feasible in cochlear implantation when the Round window-Sigmoid sinus line is posterior to the FN and the jugular bulb is not obstructing the round window. © 2018, Otology & Neurotology, Inc Daha fazlası Daha az

Purpose Upon diagnosis, distant metastases are encountered in 21-50% of neuroendocrine tumours (NETs). However, few systemic treatment options are available for the well-differentiated NETs in the metastatic stage. 177Lu-DOTATATE is one of the most effective treatments in this limited patient group. We retrospectively investigated its efficacy and effect on the survival in patients with both well-differentiated and grade III NETs who had high uptake in pretherapeutic 68Ga-DOTATATE PET/computed tomography scans. Patients and methods Patients with metastatic NETs treated with 177Lu-DOTATATE between January 2010 and November 2015 in ou . . .r department were included in this retrospective cohort. Toxicity and adverse effects were evaluated according to SWOG criteria. Progression-free survival (PFS) and overall survival (OS) rates were calculated considering the first date of treatment. Response was evaluated according to RECIST criteria. Potential predictors of survival and response were analysed. Results Patients (n=186) with metastatic NETs originating from various primary sites (bronchial, pancreatic, nonpancreatic gastroenteropancreatic-NETs, pheochromocytoma-paraganglioma and unknown primary) were treated with 1107 courses of 177Lu-DOTATATE treatment (median: 6; range: 3-12). Among 160 patients whose responses to treatment could be evaluated according to the RECIST criteria, 28.1% (n=45) had a progressive disease, 21.9% (n=35) had a stable disease, 46.9% (n=75) had a partial response and 3.1% (n=5) had a complete response. Median follow-up was 30.6 months. The Kaplan-Meier estimated median PFS was 36.4 months, mean PFS was 38 months and the mean OS was 55 months. The disease control rates in patients with WHO grades I, II and III were 74, 73 and 60%, respectively, and the OS rates were 61.9, 52.2 and 38.4 months, respectively. We observed no major renal toxicity except a minor increase (11.1%) in average serum creatinine levels. In 33.9% (n=56) of the patients, grade I toxicity; in 9.1% (n=15), grade II; and in 1.2% (n=2), grade III toxicity were observed. Conclusion 177Lu-DOTATATE therapy is an important treatment option in somatostatin receptor type-2-positive pancreatic, nonpancreatic gastroenteropancreatic-NETs, and lung NETs including metastatic NETs with an unknown primary site and significantly contributed to patients' OS. Additionally, peptide receptor radionuclide therapy may have a role in a selected subgroup of patients with grade III NET with high somatostatin receptor type-2 expression.

Origin, reality, and clinical importance of the arcade of struthers: An anatomic study

U.A. Bingol | C. Cinar | H. Arslan | S. Oksuz | O. Cetinkale

Article | 2015 | Annals of Plastic Surgery75 ( 4 ) , pp.430 - 434

The literature contains confusing and opposing views about the naming, prevalence, anatomic structure, and clinical significance of the arcade of Struthers. The conflicting rates of arcade (between 0% and 100%) prevalence found in the literature may be due to the varying definition of the arcade among the authors, as well as the dissection method. The present study aims to examine the structure to determine whether or not the arcade of Struthers exists through an anatomic dissection study of a fresh human cadaver and seeks to compare its findings with those in the literature. Twenty arms from fresh frozen cadavers were dissected. An . . . arcade of Struthers was not found in any specimen. Study concluded that its existence is unproven, and the arcade of Struthers does not exist. Copyright © 2014 Wolters Kluwer Health, Inc Daha fazlası Daha az

The use of alloplastic materials in secondary rhinoplasties: 32 Years of clinical experience

Baran, C.N. | Tiftikcioglu, Y.O. | Baran, N.K.

Article | 2005 | Plastic and Reconstructive Surgery116 ( 5 ) , pp.1502 - 1516

Background: A retrospective evaluation of the authors' 32 years of experience in revision rhinoplasty is presented. The authors suggest that iatrogenic nasal deformities are studied under four groups on the basis of their location and the affected structures: lower third, middle third, upper third, and combined deformities. The authors also present the vertical columellar incision for insertion of alloplastic implants and cartilage grafts, a genuine approach avoiding contamination with the nasal flora. Methods: A total of 182 cases were studied, as follows: lower third (n = 81), middle third (n = 65), upper third (n = 17), and combi . . .ned (n = 19) deformities. The mean age of the patients was 40 years. Results: Our follow-up was a minimum of 2 years, and some of the cases with Proplast implants have been followed for as long as 21 years. During this rather long follow-up, only two of the Proplast implants had to be removed (one because of an acute infection and the other because of a chronic infection causing extrusion after 5 years). Conclusions: The authors have always preferred to use autogenous cartilage grafts for tip deformities and Proplast implants for middle and upper third saddle nose deformities whenever necessary. Their long-term results with Proplast for more than 20 years show that alloplastic materials may be as reliable as autogenous implants if the surgical principles are met and the cases are carefully selected Daha fazlası Daha az

Article | 2014 | Eye and Contact Lens40 ( 4 ) , pp.207 - 212

Objective: To evaluate the effect of transepithelial corneal collagen crosslinking (CXL) with prolonged riboflavin application by in vivo confocal microscopy and to compare this effect with that of standard CXL with complete epithelial debridement. Methods: In eyes with progressive keratoconus, CXL procedure was performed with standard technique and transepithelial technique after prolonged riboflavin drop application for 2 hr. Patients were evaluated with in vivo confocal microscopic examination preoperatively and at postoperative months 1 and 6. Results: The depth of CXL effect was similar in both groups (i.e., 380.86±103.23 mm in . . . standard CXL group and 342.2±68.6 mm in transepithelial CXL group) (P=0.4). The endothelial cell counts and morphological parameters (i.e., pleomorphism and polymegathism) were not significantly affected in both groups (P >0.05 for all). In the standard CXL group, in vivo confocal microscopy revealed anterior stromal acellular hyperreflective honeycomb edema with posteriorly gradually decreasing reflectivity and increasing number of keratocytes and some sheets of longitudinally aligned filamentary deposits. The keratocytes were seen to repopulate in the posterior-to-anterior direction. In transepithelial CXL group, although the depth of CXL effect was similar, less pronounced keratocyte damage, extracellular matrix hyperreflectivity, and sheets of filamentary deposits at the posterior stroma was observed. Conclusions: Transepithelial CXL with prolonged peroperative riboflavin application can achieve similar depth of effect in the stroma with less pronounced confocal microscopic changes as compared with the standard CXL with complete epithelial debridement Daha fazlası Daha az
