A radiological and laboratory assessment of polyethylene wear in failed total hip replacement

This study assessed the reliability of radiological assessment of polyethylene wear in loose total hip replacements (THRs) by comparing it with a laboratory assessment using the shadowgraph technique. It was performed in Avon Orthopaedic Centre, Southmead Hospital, from September 1997 to June 1998. True linear wear depth measured using the shadowgraph technique was 42% greater than that determined from the radiological femoral head eccentricity in standard non-weightbearing plain x-rays. There was an inverse statistically significant correlation between cup inclination angle and the volumetric wear rate. The linear wear rate, as determined with the shadowgraph technique, was greater in retrieved cups during the first six years postoperatively, but reduced to a lower level in cups retrieved after that time of service.</jats:p

Clinicopathologic and prognostic significance of cyclooxygenase-2 expression in endometrial carcinoma

Backgroud: Endometrial carcinoma is the most common malignancy of the female genital tract in the Western world. COX-2 is highly expressed in endometrial carcinoma, but there is controversy regarding its clinical role and its possible prognostic role. COX-2 expression was determined by immunohistochemistry and was correlated to standard clinicopathologic variables in a series of primary untreated endometrial carcinoma patients. COX-2 as an accurate predictor of the disease was also analyzed. Methods: One-hundred and ten cases of primary untreated endometrial carcinoma hosts who were admitted to the Department of Obstetrics and Gynecology, University General Hospital of Alexandroupolis, were investigated. Immunohistochemistry was performed using rabbit polyclonal antiserum against human COX-2. Results: Twenty-eight patients (25.5%) were scored as COX-2 positive. A statistically significant association was found between COX-2 overexpression and FIGO stage (p=0.010). A positive correlation was also found with histological grade (p=0.019) and myometrial invasion (p=0.026). No significant association was found with histologic type of the tumor (p=0.164). COX-2 positive patients had a significant association with sort survival (p=0.028). Conclusions: COX-2 expression is an independent clinicopathologic factor and an independent prognostic factor in endometrial carcinoma. It could be used to plan treatment modalities for hosts

Reliability and validity of the Diabetes Eating Problem Survey in Greek adults with type 1 diabetes mellitus

Ιn the management of type 1 diabetes mellitus (T1DM), dietary therapy and the maintenance of a healthyΙn the management of type 1 diabetes mellitus (T1DM), dietary therapy and the maintenance of a healthy body weight (in conjunction with insulin therapy) are significantly associated with good glycemic control and complication reduction. However, a diabetic patient&apos;s increased focus on diet and weight control,although necessary, can lead to disturbed eating habits, medical complications, and &quot;resistance&quot; to treatment. The term &quot;diabulimia&quot; refers to the eating disorder in which patients with T1DM take less insulinin order to control their weight. Currently there is no valid questionnaire in the Greek language for the detection of eating disorders in T1DM. This study examines the psychometric properties of the Greek version of the Diabetes Eating Problem Survey-Revised (DEPS-R), a questionnaire that assesses the risk of &quot;diabulimia&quot;in patients with T1DM. 100 outpatients with a T1DM diagnosis of over one year -71 women and 35users of a continuous insulin infusion pump- were asked to complete the DEPS-R questionnaire translated into Greek (0-80 score range, &gt;20 indicating high risk of disorders) along with the EAT-26 (0-78 score range,&gt;20 indicating high risk of pathological eating behaviours or eating disorder) and the Beck Depression Inventory (BDI-ΙΙ) (0-63 score range, &gt;14 indicating high risk of major depressive disorder). The Greek versionof the DEPS-R showed strong internal consistency and construct validity (Cronbach&apos;s alpha=0,89 in total,0,90 in females and 0,85 in males). Factorial analysis revealed 4 factors (diet, weight loss, insulin use and compensatory behaviors) accounting for 65.68% of the total variance (19.90%, 18.50%, 15.64% and 11.65%of the total variance respectively). In addition, 35% of the sample scored above 20 on the EAT-26, 26% rated above 14 on the BDI-II and 40% had a score above 20 on the DEPS-R, while the average score was 19.22. The sound psychometric properties of the DEPS-R scale were confirmed for a Greek sample with T1DM suggesting that it could be used as a reliable tool for the detection of diabulimia. In addition, we found that Greek patients with T1DM appear to have an increased risk of developing eating disorders and depression

Oculomotor nerve palsy due to posterior communicating artery aneurysm: Clipping vs coiling

Objective: Posterior communicating artery aneurysms (PCoAA) usually present with brain hemorrhage, but they might present with oculomotor nerve palsy (ONP) in about one out of five patients. Treatment options include endovascular coiling and surgical clipping. The present analysis aims to compare the two treatment options for ONP due to PCoAA in terms of complete recovery and related parameters. Methods: A comprehensive literature search was performed for studies published between 2000 and 2019 on ONP due to PCoAA. The included studies were divided into two categories—surgical clipping (group A) and endovascular coiling (group B). The collected data were statistically processed with SPSS version 25. Results: There was a significant difference between the two treatment groups regarding complete recovery of ONP (P < 0.001), suggesting superiority of the surgical clipping. The correlation analysis showed no correlations for group A. Group B had negative and positive correlations, showing that endovascular coiling results in higher rates of complete ONP recovery for elderly patients. Conclusion: Surgical clipping is superior to endovascular coiling in terms of complete recovery among patients with ONP due to PCoAAs. Endovascular coiling seems to benefit older patients. While no recommendations exist for the treatment of ONP due to intracranial aneurysms, an increasing number of studies imply the superiority of operative clipping. © 2021 Elsevier Masson SA

Incidental Thyroid Carcinoma Diagnosed after Total Thyroidectomy for Benign Thyroid Diseases: Incidence and Association with Thyroid Disease Type and Laboratory Markers

Objective. Currently, total thyroidectomy (TT) is widely used to treat benign thyroid diseases and thyroid carcinoma. The differential diagnosis between benign and malignant thyroid disorders and the potential identification of thyroid microcarcinomas with biochemical markers remain controversial. This retrospective study aimed to estimate the prognostic validity of thyroid autoantibodies, thyroglobulin (Tg), and the thyroid disease type in diagnostic approaches regarding the co-existence of incidental thyroid carcinoma (ITC) with benign thyroid diseases. Methods. A cohort of 228 patients was treated with TT for benign thyroid disorders between 2005 and 2010. Thyroid autoantibodies and Tg were preoperatively estimated. Patients were classified according to the preoperative and histologically established diagnoses, and the median values of the biochemical markers were compared between the groups. Results. ITC was detected in 33/228 patients and almost exclusively in the presence of nontoxic thyroid disorders (). There were no statistically significant differences in the median values of the biochemical markers between the benign and malignant groups. There was also no significant association between ITC and chronic lymphocytic thyroiditis. Conclusions. The co-existence of ITC with benign and especially nontoxic thyroid diseases is significant, and treatment of these disorders with TT when indicated can lead to the identification and definitive cure of microcarcinomas. Further studies are required to establish precise markers with prognostic validity for TC diagnosis

Long-term bone marrow cultures (LTBMC) from essential thrombocythemia (ET) patients with or without JAK2617V&gt;F mutation

Approximately half of essential thrombocythemia (ET) patients and almost all with polycythemia vera (PV) bear the activating JAK2617V&gt;F point mutation, which arises at the multipotent haemopoietic progenitor cell level. Although ET is mainly characterized by megacaryocyte proliferation, the cases that are positive for the JAK2617V&gt;F mutation also show increased bone marrow cellularity and higher erythrocyte and granulocyte counts. After establishing short- and long-term bone marrow cultures we found that the frequency of committed haemopoietic progenitors in the bone marrow, was not increased in JAK2617V&gt;F positive ET compared to the negative ones, whereas in long-term cultures (LTBMC) JAK2617V&gt;F positive ET display a growth pattern more similar to that observed in LTBMC produced by PV marrow cells. Our data support the notion that JAK2617V&gt;F positive ET and PV represents a continuum spectrum of alterations within the same disease. © 2008 Elsevier Ltd. All rights reserved
