ABSTRACT: Lip carcinoma is one of the most common cancers of the head and neck region. Lower lips are more frequently affected. Squamous cell carcinoma accounts for more than 95% of the cases. The aim of treatment is to achieve the highest cure rates with adequate excision with clear surgical margins while leaving the smallest defect sizes behind for reconstruction. Excised tissue is known to shrink when removed, in relation with its retractile properties. In this study, the evaluation of the amount of shrinkage in excised lip cancer specimens and determination of the relation between surgical and histopathologic margins were aimed.The study included 21 consecutive excised lip specimens for the treatment of squamous cell carcinoma of the lip. The volume of the specimen, tumor length, and margin distance measurements were measured and recorded step by step from before surgical excision to histopathologic evaluation. Specimens were evaluated in a standardized fashion by the same pathologist after 48 hours of fixation. For data analysis, Number Cruncher Statistical System 2007 and Power Analysis and Sample Size 2008 Statistical Software (Kaysville, UT) were used.The surgical margins of the excised lip specimen shrink up to 41% to 47.5% from before excision to histopathologic evaluation. The most significant step was the excision step, followed by the formalin fixation step. The histopathologic process itself and the duration of formalin fixation did not result a significant change in surgical margins. The tumor tissue itself did not show a significant shrinkage. © 2014 by Mutaz B. Habal, MD. Source

Mitral valve stenosis is a common manifestation of chronic rheumatic heart disease. In rheumatic mitral valve stenosis (RMVS) patients, left atrial spontaneous echo contrast (LASEC) is an independent predictor of thromboembolism risk. While the anticoagulant therapy algorithm for atrial fibrillation patients is clear, the clinical tools determining high-risk patients in sinus rhythm are insufficient. Our aim is to examine the relationship between CHA2DS2-VASc score in RMVS patients in sinus rhythm and the presence of LASEC. The patients with RMVS upon presentation to the cardiology polyclinic were included in this cross-sectional study consecutively, and CHA2DS2-VASc scores were calculated. All patients were evaluated with transthoracic and transesophageal echocardiography and were divided into two groups as those with and without LASEC. The total number of patients was 265, with LASEC determined in 97 (36.6 %) and not determined in 168 (63.4 %). No significant differences in terms of age, gender, and body mass index were found between the groups. Patients with LASEC had higher mean CHA2DS2-VASc score than patients without LASEC (2.10 ± 1.21 vs. 1.11 ± 0.7, respectively; p < 0.001). In the multivariate logistic regression analysis, it has been determined that there is an independent association between the existence of LASEC and CHA2DS2-VASc score (OR 3.176, CI 1.937–5.206; p < 0.001). The ROC analysis revealed that CHA2DS2-VASc score 2 or more predicted presence of LASEC with a sensitivity of 71 % and a specificity of 82 % (AUC 0.746, 95 % CI 0.682–0.810). The CHA2DS2-VASc score could be useful marker to detect prothrombotic state in patients with RMVS in sinus rhythm. © 2015 Springer Japan Source

Supportive Care in Cancer | Year: 2016

Background: Terminal stage cancer patients experience anxiety about death and pessimism about the future. They usually fear that as they approach death, their pain will increase, they will lose their reputation, and they will be alone. However, few studies have evaluated the loneliness that these cancer patients feel. This was a cross-sectional and definitive study that evaluated the feeling of loneliness in terminal cancer patients. Methods: In total, 55 cancer patients with terminal cancer who were hospitalised for palliative therapy between 14 November 2014 and 14 January 2015 in the Okmeydanı Training and Research Hospital were included in the study. The patients were given a questionnaire form that included sociodemographic properties and University of California Los Angeles Loneliness Scale to collect data. Results: Loneliness was detected as 53.61 ± 9.29. There was no relationship between sociodemographic data and loneliness (p > 0.05). Regression analysis revealed that family support and sharing of emotional stress were related to the level of loneliness (p < 0.05). More than half of the patients needed psychological support because they could not handle the situation. Conclusions: Terminal stage cancer patients felt lonely in general, and patients with a lack of visitors and family support experienced a higher level of loneliness. © 2016, Springer-Verlag Berlin Heidelberg.

Pediatric Neurosurgery | Year: 2011

Lumbar disc herniation (LDH) is a very rare clinical entity in the pediatric age group, therefore only a few clinical studies have until now investigated the clinical behavior of pediatric LDH. The natural clinical history, postoperative neurological recovery with radiological follow-up and quality of life related to the disorder continue to be unknown. We prospectively planned and designed two groups of LDH patients scheduled for surgery in this study. The operations were performed by the same surgeon in a randomized fashion. The first group consisted of pediatric patients and the second group of adult patients. Both groups contained 32 cases. Postoperative neurological recovery was assessed using the visual analog scale and Aberdeen Low Back Pain Scale. Postoperative peridural fibrosis was also evaluated in postcontrast magnetic resonance sections. After 3 years of follow-up, all parameters were significantly better in the pediatric LDH group with no recurrence of the disease. The pediatric LDH group was postoperatively better than the adult group both clinically and radiologically. Although LDH seems a catastrophic disease in the pediatric age group, the clinical picture and neurological recovery have a significantly more benign course than in adult patients even in operated cases.

Osteoarthritis is one of the most common chronic diseases and associated with increased cardiovascular comorbidity and deaths. Elastic properties of aorta are closely associated with cardiovascular mortality and morbidity. In our study, we aimed to evaluate aortic stiffness in primary osteoarthritis patients. A total of 160 patients including 80 patients with primary knee osteoarthritis and 80 controls without osteoarthritis were included in the study. Additionally, osteoarthritis patients were divided into four subgroups according to the severity of the disease. Aortic parameters were evaluated by using transthoracic echocardiography method. While measurements of aortic stiffness of osteoarthritis group were higher compared to the control group (p<0.01), aortic strain and aortic distensibility measurements of osteoarthritis group are lower than the control group (p< 0.01). Additionally, it was determined that as the severity of osteoarthritis increased also aortic stiffness increased highly significantly (p = 0.001). Presence and severity of osteoarthritis are closely associated with elastic properties of aorta, which are correlated with cardiovascular mortality and morbidity. © 2015, The Author(s) 2015. Source
