OCLC Number/Unique Identifier: 8598594231

Purpose: The time course of muscle stiffness of muscles around the shoulder joint and the scapula was investigated according to the degree of muscle weakness. This study was conducted to clarify the recovery process of muscle hardness of the muscles surrounding the shoulder joint and the scapula after the shoulder internal and external rotational exercises. Methods: Participants were 7 healthy men (23.6 ± 1.4 yr), repeated internal and external rotations of the shoulder joint until the mean work of three internal and external rotations each was less than 90%, 80%, or 70% of the standard. Muscle hardness of the supraspinatus muscle, the infraspinatus muscle, and the rhomboideus muscle was measured before, immediately after, and 1to 72 hr after each bout of exercise. Muscle hardness was measured as Strain ratio using an ultrasound real-time tissue elastography. In addition, the rates of change were calculated using muscle hardness before exercise as the standard, to compare differences in the rate of change after exercise between conditions. Results: The rates of change of the Strain ratio between measurements taken before and after exercise were compared among conditions for the infraspinatus muscle. Results were -7.1 ± 5.3, -15.2 ± 10.3, and -25.0 ± 8.8, respectively, at 90%, 80%, and 70%, with a significant difference between a decrease to 90% and to 70% (p < 0.05). Significant difference was found in the change over time for the infraspinatus muscle only between values obtained immediately after exercise and after 72 hr at a decrease to 70% (p < 0.05). Conclusion: Those results described above demonstrated that the infraspinatus muscle and the supraspinatus muscle were harder immediately after exercise when the shoulder joint was at a higher degree of muscle weakness, and demonstrated that the change was likely to be recovered after 72 hr.

3-Dimensional Versus 2-Dimensional Comparison of Knee Valgus Collapse during Vertical Jump: Clinical Implications for ACL Risk of Injury Assessment

Published on: 21st March, 2017

OCLC Number/Unique Identifier: 7286358320

Time-efficient screening of lower extremity biomechanics to identify potential injurious movement patterns is crucial within athletic medicine settings. When considering biomechanical risk factors for anterior cruciate ligament injuries, several screening tests have been used to assess dynamic knee valgus. Current methods involving 3-dimensional motion capture systems are considered gold standard for such assessment; however, these methods are time consuming and require expensive materials. This study investigated the use of 2-dimentional kinematic evaluation during a standardized vertical jump athletic assessment to screen for potential lower extremity risk of injury. 50 collegiate athletes, 25 male and 25 female, from various sports participated in the study. The vertical jump was chosen because it is a common performance evaluation test that is regularly performed several times a year, providing consistent opportunities for screening while not creating additional obligations for the student athletes. Results showed that the 2-dimentional evaluation method had strong correlations (P<0.0001) with the gold standard 3-dimensional evaluation, suggesting that an accelerated 2-dimentional screening process can be used as a first step to screen for potential injurious lower extremity movement patterns.

OCLC Number/Unique Identifier: 7286355386

The research investigated the perception of nutrition and exercise as a tool in controlling Cardiovascular Diseases (CVDs) among elderly civil servants in Anambra State of Nigeria. A total of 250 respondents comprising 150 elderly academic staff Nnamdi Azikiwe University Awka and 100 senior civil servants in the Anambra state civil service, who willingly, volunteered to participate in the study. Their ages ranged between 55-65 years purposively selected. The instrument for data collection was a self-structured questionnaire, with a reliability value of 0.73 using the test retest method. All data collected were subjected to descriptive statistics of frequency, percentages and chi square tested at 0.05 level of significance. Findings from the study showed that nutrition (diet) and exercise have significant effect in the prevention/control of (CVDs) among the elderly. It is therefore recommended that at the civil service secretariats, universities and other establishments/parastatals, should establish high standard eateries (restaurants) where qualified caterers, would regularly provide nutritious diet, at subsidized rate for workers in this category. In order to enable these class of workers have at least one good meal per day, in addition to a mandatory one- work-free afternoon (2.00pm-4.00pm) for routine/regular physical exercises for these class of workers.

Comparison of selected lower limb biomechanical variables between university of ibadan sportsmen with and without patellofemoral pain syndrome

Published on: 16th August, 2019

OCLC Number/Unique Identifier: 8235051929

Patellofemoral pain syndrome is common among athletes who participate in jumping, running and pivoting sports. The aim of this study was to compare selected lower limb biomechanical variables between University of Ibadan students (athletes) with and without patellofemoral pain syndrome. The research design for this study was a case control survey and a purposive sampling technique was used to recruit participants. Two hundred and twenty two (191(85.8%) males and 31 (14.2%) females) sportsmen participated in this study. The participants’ age was between 20-29 years. Fourty sportsmen tested positive to Clarke’s test while 27 sportsmen tested positive to Eccentric step test. Measurements of static quadriceps angle, hamstring tightness and navicular height were taken for all participants. Data were analyzed using descriptive statistics of mean, standard deviation, percentages and inferential statistics of Independent ‘t’ test. The mean lower limb biomechanical variables of participants with patellofemoral pain syndrome were 13.18 ± 2.37°, 106.46 ± 16.11° and 1.21 ± 0.61 cm while those without were 13.65 ± 2.46°, 128.95 ± 25.36° and 1.03 ± 0.58 cm for static quadriceps angle, hamstring tightness and navicular height respectively. There was no significant difference (p > 0.05) in selected lower limb biomechanical variables between participants with and without patellofemoral pain syndrome. In conclusion there was no significant difference in static quadriceps angle, hamstring tightness and ankle pronation between participants with and without patellofemoral pain syndrome. It was recommended that PFPS development is probably multifactorial with other functional disorders of the lower extremity apart from the selected variables.

Parents Take-On Concussion: Advances in Sideline Research and Culture in Youth Sports

Published on: 16th March, 2017

OCLC Number/Unique Identifier: 7286354252

Identifying concussion and initiating removal from play is challenging for even the most diligent youth sports organizations. Empowering parents to implement removal from play protocols and sideline testing may be the most practical plan at community levels to protect young athletes. We developed paradigms for community-based youth sports teams that incorporated both standard concussion protocols and research investigations. The research studies were designed to determine how sideline tests of vision, cognition and balance augment the capacity for parents and other responsible adults to identify youth athletes with concussion in ice hockey, football, lacrosse and cheerleading. Research-based sideline tests were performed at pre-season baseline sessions and during the season at the time of injury or as soon as symptoms were recognized by trained volunteer parent team testers. The combination of standard concussion protocols and research studies were performed for 510 athletes, aged 5-17 years, over 2.5 years through 5 athletic seasons. To implement the protocols and studies, approximately 80 student volunteers and parents were educated and trained on early concussion recognition and on baseline and sideline test administration. Over 80% of parent-identified head injuries were physician-confirmed concussions. Of the sideline tests performed, over two-thirds were administered within 24 hours of injury; the rest were performed within an average of 2.6 days post-injury since some athletes had delayed development of symptoms. Removal from play guidelines and standard concussion evaluation protocols were maintained in the context of the sideline testing research investigations. Based on this observational study, parents of youth athletes can be successfully empowered to perform rapid sideline tests in the context of existing concussion protocols. Implementation of objective testing may improve concussion identification and shift the culture of advocacy and responsibility towards parent groups to promote safety of young athletes. Ongoing investigations will further examine the impact of these programs on concussion management in youth sports.

Left Atrial Remodeling is Associated with Left Ventricular Remodeling in Patients with Reperfused Acute Myocardial Infarction

Published on: 7th December, 2016

OCLC Number/Unique Identifier: 7286353354

Background: Left atrial volume (LAV) has been established as a sensitive marker of left ventricular (LV) diastolic function and as an independent predictor of mortality in patients with acute myocardial infarction (AMI). LA remodeling and its determinants in the setting of AMI have not been much studied. Methods: We studied 53 patients with anterior AMI and a relatively preserved LV systolic function, who underwent complete reperfusion and received guidelines guided antiremodeling drug management. LA and LV remodeling were assessed using 2D echocardiography at baseline and 6 months. LAV indexed for BSA (LAVi) was used as the index of LA size and further LA remodeling. Results: LAVi increased signifi cantly at 6 months compared to baseline [28.1 (23.0-34.5) vs 24.4 (19.5- 31.6) ml/m2, p=0.002] following LV end diastolic-volume index change [56.8 (47.6-63.9) vs 49.5 (42.0-58.4) ml/m2, p=0.0003]. Other standard LV diastolic function indices did not show any signifi cant change. Univariateanalysis showed a strong positive correlation of LAVi change with BNP levels at discharge, LV mass index and LV volumes indices change, throughout the follow up period. Multivariate regression analysis revealed that BNP plasma levels was the most important independent predictor of LA remodeling (b-coef.=0.630, p=0.001). Conclusions: Despite current antiremodeling strategies in patients with AMI, LA remodeling is frequently asssociated with LV remodeling. Additionally LAVi change in the mid-term reflects better than standard echocardiographic indices LV diastolic filling impairment.

Cardiomyopathies - The special entity of myocarditis and inflammatory cardiomyopathy

Published on: 1st July, 2019

OCLC Number/Unique Identifier: 8192807959

Cardiomyopathy is a heart muscle disease with structural and functional myocardial abnormalities in the absence of coronary artery disease, hypertension, valvular disease, and congenital heart disease. However, it has become clear that diverse etiologies and clinical manifestations (e.g. arrhythmogenic right-ventricular cardiomyopathy/dysplasia (ARVC/D), ARVD/C, left-ventricular non-compaction cardiomyopathy (LVNC)) are responsible for the clinical picture of dilated cardiomyopathy (DCM). The American Heart Association (AHA) classification grouped cardiomyopathies into genetic, mixed and acquired forms, while the European Society of Cardiology (ESC) classification proposed the subgrouping of each major type of cardiomyopathy into familial or genetic, and nonfamilial or nongenetic, forms [1-4]. Cardiomyopathies are clinically heterogeneous diseases, and there are differences in sex, age of onset, rate of progression, risk of development of overt heart failure and likelihood of sudden death within each cardiomyopathy subtype [5]. Because of the complex etiology and clinical presentation, the diagnostic spectrum in cardiomyopathies spans the entire range of non-invasive and invasive cardiological examination techniques including genetic analysis. The exact verification of certain cardiomyopathies necessitates additional investigations. So, histological, immunohistological and molecular biological/virological investigations of endomyocardial biopsies are the gold standard to confirm the diagnosis of an inflammatory cardiomyopathy (DCMi) [6-10]. This review focuses on myocarditis and inflammatory cardiomyopathies underlying an immune-mediated process or persistent viral infection.

Assessment of lipid and hematological profile among blood donors in European Gaza Hospital, Palestine

Published on: 16th July, 2019

OCLC Number/Unique Identifier: 8192805778

Background: There is an important shortage of blood in the greatest blood banks worldwide to meet up with requirements for numerous medical interventions. Limited studies have associated regular blood donation to the lowering of lipid function parameters. Assessing the lipid function is a classical method of evaluating an individual’s risk for coronary heart disease. Objective: The general goal of the study is to determine lipid and hematological profile among blood donors in European Gaza Hospital, Palestine. Materials and Methods: This study was a case-control study that involved 120 male, 40 of whom were regular blood donors (study group), 40 first time donors and 40 non- donors (control group) aged between 18-60 years. A volume of 5ml venous blood was drawn from each fasting participant into a dry biochemistry screw-capped tube. This was allowed to clot and the serum was used to determine total cholesterol (TC), triglycerides, High-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (HDL-C), while HDL-C/LDL-C and TC/LDL ratio were calculated by using the following formula. Anthropometric parameters (weight, height) of donors were measured using standard protocol. The height (in meter), weight (in kilogram) were used to calculate the body mass index (BMI) using the following formula. BMI= weight (kg)/ (height in meter)² and blood was collected from each participant in EDTA (for hematocrit, ESR). Three groups were matched for age and BMI. Data were analyzed using SPSS version 23. Chi-square (χ²) was used to compare the relationship between categorical variables, ANOVA was used to measure the difference between means. Data were summarized using tables, pie charts, histograms. A P-value < 0.05 was considered to be statistically significant for all tests conducted. Results: The mean total cholesterol (169±10.85 mg/dl), triglycerides (116±9.73 mg/dl), HDL (54±2.5 mg/dl ), LDL (92±11.4mg/dl), LDL/HDL ratio (1.73±0.25) and TC/HDL ratio (3.16±0.26) were lower in the regular blood donors than the first time donors(198±10.13, 179±5.82, 42.33±1.6, 120±11.2, 2.85±0.36, 4.7±0.40) and non- donors (202±10.19, 180±12.68, 41.75±1.4, 125±11.7, 2.99±0.33, 4.86±0.32) respectively and statistically significant (P < 0.05).The mean ESR (6.63±0.87mm/hr) was lower statistically significant in the regular blood donors than the first time donors (7.40±1.17) and non- donors (7.60±1.48) respectively (P < 0.05). The mean HCT (42.98±0.86%) was lower statistically significant in the regular blood donors than the first time donors (44.63±0.90) and non- donors (44.75±0.74, P < 0.05). Conclusion: Regular donors have reduced risk of developing coronary heart disease as reflected by the low total cholesterol, triglycerides, LDL-c, LDL-c/HDL-c ratio, TC/HDL-c ratio and HCT and high HDL. BMI in regular donor was less than the donor for the first time and did not donate, but did not reach the statistical significance. Also in our study regular donors have reduced risk of developing inflammation as reflected by low ESR.

The Renin-Angiotensin System: Alamandine is reduced in patients with Idiopathic Pulmonary Fibrosis

Published on: 20th November, 2019

OCLC Number/Unique Identifier: 8440576482

Idiopathic Pulmonary Fibrosis (IPF) is a chronic and progressive disease without treatment that leads to death. Therefore, to control its progression to pulmonary hypertension is still a challenge. Moreover, there is no study that has investigated the Renin-Angiotensin System in patients with IPF. Objective: Verify the plasma concentrations of Angiotensin I, Angiotensin II (AngII), Angiotensin-(1-7) [Ang- (1-7)] and Alamandine in patients with IPF. Methods: Ten IPF patients, with or without PH, were included, and ten controls matched by sex and age. Quantitative plasma peptide concentrations (PPC) were expressed as mean and standard deviation or median and interquartile range. The Student Newman-Keuls t test was used for parametric data, Mann-Whitney for nonparametric data and, to compare proportions, the Fisher exact test was performed. The associations between clinical variables and the PPC were evaluated by Pearson or Spearman correlation coefficients. A p ≤ 0.05 was considered statistically significant. Results: The Alamandine plasma concentration was significantly (365%) lower in the IPF group and positively associated (r = 0.876) with pulmonary artery pressure (PAP). In addition, only in control group, the forced expiratory volume (FEV1%) was positively associated (p = 0.758) with Ang-(1-7). Conclusion: This study showed, for the first time, that there is a decrease in Alamandine participation in patients with IPF. The ACE-AngII-AT1 axis may be more active in this disease. In addition, our results suggest that Alamandine might be compensating the increase in PAP, as well as the Ang-(1-7) is improving the forced expiratory volume.

Readjustment of antithrombotic therapy in stroke-patients owing to transesophageal echocardiography findings

Published on: 26th November, 2019

OCLC Number/Unique Identifier: 8440612661

Objectives: Cardioembolic etiology is a frequent source of ischemic stroke. Echocardiogram is the mainstay of cardioembolic source detection with regard to plan secondary stroke management, however it remains unclear how often clinically actionable findings are provided hereby. In addition, it is uncertain whether echocardiography should be performed transthoracic or transesophageal (TEE). In a monocenter study, we evaluated the frequency of pathological findings from TEE evaluation in patients with ischemic stroke with suspected cardioembolic and cryptogenic source and determined whether there was an associated adjustment in the prescribed administration of antithrombotic therapy. Materials and Methods: Over a 21-month period (2012-2013), we enrolled 143 patients in a prospective monocenter study (mean age ± standard deviation, 70 ± 12 years; females, 44.1%) who were admitted to the Department of Neurology at the University of Lübeck due to ischemic stroke and who underwent TEE due to supposed cardiac embolism. We assessed the presence of atrial fibrillation; days from admission to TEE; and TEE findings, including atrial septal aneurysm, thrombogenic aortic arch, valve failure, presence of left atrial thrombus, and patent foramen ovale. Demografic information and medical history were drawn from patient records and the hospital information system. Results: On average, TEE was performed 4 days after admission to the hospital. Left atrial thrombus was detected in 3 patients (2.1%), patent foramen ovale (PFO) in 27 (18.9%), atrial septum aneurysm in 17 (11.9%), and thrombogenic aortic arch in 29 (20.3%). Findings from TEE were commonly associated with therapeutic adjustment; antiplatelet therapy increased from 30.1% to 80.4%, oral anticoagulation therapy increased from 2.8% to 27.3%. Conclusion: Findings from TEE for the evaluation of ischemic stroke lead to frequent adjustment of prior antithrombotic therapy, antiplatelet as well as anticoagulation.

Recurrence of atrial fibrillation after pulmonary vein isolation, should we change the energy and technique?

Published on: 3rd April, 2020

OCLC Number/Unique Identifier: 8576354289

Background: Pulmonary vein isolation (PVI) is the accepted standard nowadays for atrial fibrillation (AF) ablation. The most widespread ablation techniques are cryoballoon (CB) and point-by-point radiofrequency (RF) ablation. Comparative studies between both techniques have shown their equivalence for the first ablation procedure, but no trial has explored the potential incremental benefit of crossing over the ablation technique after AF recurrence. Objective: To explore the potential incremental benefit of a crossover ablation strategy for AF recurrences, comparatively with repeating the same ablation energy used for the first procedure. Methods: Retrospective analysis of patients undergoing a second AF ablation procedure after documented AF recurrence. Patients were excluded if all 4 PV were isolated at the beginning of the second procedure or extra-PVI ablation was used for the second procedure. Crossover group (n = 16) included patients in which two different techniques were used for the first and second procedure (CB-RF or RF-CB). Control group (n = 23) for those with same ablation procedure (RF-RF of CB-CB). Acute procedure end-point was PVI of all four pulmonary veins. Patients were followed-up at 3, 6, and 12 months with an electrocardiogram and a 24 h-holter. Arrhythmia-free survival at 1 year after the second ablation procedure was studied, comparing efficiency and safety of the two approaches (crossover vs. same energy). Success was defined as freedom from AF or atrial tachycardia lasting > 30 s off antiarrhythmic drugs (AADs) Results: A cohort of 39 paroxysmal and persistent AF patients was analyzed. PVI after the second procedure was 100% in all patients in both groups. There were no baseline relevant differences between the two groups. No deaths or hospitalizations occurred during follow up (data censored at 24h moths). At 1 year, arrhythmia free-survival was significantly higher in the crossover group compared to control group [93,3% vs. 47,8%; HR 0.19 (0.06-0.66);p = 0,009]. Conclusion: Crossing the ablation technique (point-by-point radiofrequency or cryoballoon PVI) after AF recurrence significantly improved arrhythmia free-survival at one year, despite no difference in acute success (PVI isolation). Randomized controlled trials with a higher amount of patients are needed to confirm the results and widespread this approach.

Inter-Observer Variability of a Commercial Patient Positioning and Verification System in Proton Therapy

Published on: 6th February, 2017

OCLC Number/Unique Identifier: 7286354964

Purpose:Accurate patient positioning is crucial in radiation therapy. To fully benefit from the preciseness of proton therapy, image guided patient positioning and verification system is typically utilized in proton therapy. The purpose of this study is to evaluate the inter-observer variability of image alignment using a commercially available patient positioning and verification system in proton therapy. Methods:The VeriSuite patient positioning and verification system (MedCom GmbH, Darmstadt, Germany) provides a six degrees of freedom correction vector by registering two orthogonal x-ray images to digitally reconstructed radiograph (DRR) images that are rendered in real time from the planning computed tomography (CT) images. Six cases of various disease sites, including brain, head & neck, lung, prostate, pelvis, and bladder, were used in this study. For each case, the planning CT images and a daily orthogonal x-ray portal image pair were loaded into the VeriSuite system. The same set of x-ray images and CT images for each case were reviewed and aligned separately by each of the 10 radiation therapist, following the clinical procedure for the corresponding disease site. The resulting correction vectors were then recorded and analyzed. Results:Our study shows that the inter-observer variation (One standard deviation) in image alignment using the VeriSuite system ranged from 1.2 to 2.0 mm for translational correction and from 0.6 to 1.3 degrees for rotational correction for the six cases. The use of fiducial markers for prostate patient alignment achieved the least inter-observer variation while the bladder case produced the largest. Conclusions:Inter-observer variation in image alignment could be relatively large, depending on the complexity of patient anatomy, image alignment approach, and user experience and software limitations. Automatic registration and fiducial markers could potentially be used to align patient more accurately and consistently. To ensure adequate tumor coverage in proton therapy, inter-observer variability in patient alignment should be carefully evaluated and accounted for in patient setup uncertainty analysis and treatment planning margin determination.

Empirical formulae for calculating γ-ray detectors effective solid angle ratio

Published on: 27th January, 2017

Determination of the detector efficiency using volumetric cylindrical sources is very important in various scientific and industrial fields, especially in the field of quantitative analysis. To calculate the absolute activity of any sample, the full-energy peak efficiency (FEPE) of the detector is needed. By applying the efficiency transfer method, the FEPE of the detector would be determined easily without using the standard sources. This approach depends on two main factors. The first one, is the reference efficiency of the reference source, which is determined experimentally, and the second one, is the calculation of the effective solid angle ratio between the sample and the reference source geometries. This work introduces an empirical formula for calculating the second factor for using two different sizes of NaI(Tl) detectors. The validity of this empirical formula was successfully demonstrated by comparing the calculating values with the experimental values.

New Approach for Analysing the Discrepancy of Pretherapeutic Tc-99m and Intra-therapeutic I-131 uptake in Scintigraphies of Thyroid Autonomies using a Parametric 3D Analysis Program

Published on: 2nd January, 2017

OCLC Number/Unique Identifier: 7286427358

Introduction: Radioiodine therapy is a standard procedure in thyroid autonomy treatment. Discrepancies in the visual comparisons of the scintigraphies prepared for this purpose using Tc-99m-O4- and I-131 have been known for years. In this study a new method is used to calculate and perform a quantitative comparison of both uptakes using subtraction analysis and 3D imaging. The results and their causes are discussed together with practice-relevant conclusions for better clinical results. Material and Methods: The new method was used in 38 patients with thyroid autonomies for the subtraction analysis of standardized pretherapeutic and intratherapeutic scintigraphies. The parametric distribution of activity was calculated absolutely and as a percentage and displayed three-dimensionally. These results were compared with the visual assessment of the different scintigraphies by the experts. Inclusion criteria were pretherapeutic and intratherapeutic hyperthyroidism without medication affecting the thyroid. The time difference between acquiring the scintigraphies was 28 days maximum. Results: Activity distribution was visually discrepant in 39.5% of cases. 60.5% displayed comparable uptake. The calculated values showed reversed results after applying the new method. The results using our method show a higher rate of calculated discrepancies compared with visual analysis. Conclusion: Accurate functional imaging of the thyroid is next to further aspects very important in establishing the diagnosis and deciding about the therapy activity for thyroid treatment. In combination with clinical symptoms and laboratory values, Tc-99m-O4 - scintigram can be used for an orientated, preliminary assessment of functional disorders of the thyroid. But because of the higher rate of found discrepancies, the solely use of Tc-99m-O4 - scintigram is not always capable for exact and reliable diagnosis. The known reason for this is most probably due to the different biokinetics of both radiopharmaceuticals, which can be imaged more sensitively with this method. Consequently, a scintigram should be performed in the pretherapeutic radioiodine uptake test. Despite higher costs and radiation exposure, alternatively, pretherapeutic use of other diagnostic iodine isotopes like I-123 or -124 should be discussed, because they could overcome the limitation of the different biokinetics. Following this approach the preliminary assessment using Tc-99m-O4 - scintigraphy can be precised and double checked to improve diagnostic confi dence and treatment results for a better outcome of the patients.

Review of Stereotactic and Neuronavigation Brain Biopsy Methods in the Dog

Published on: 1st November, 2018

OCLC Number/Unique Identifier: 7912354081

Objective: To perform a review of brain biopsies in the canine species and determine if it is possible to compare the stereotactic and neuronavigation results. Method: A search was performed in NCBI’s PubMed database for stereotactic or neuronavigational canine brain biopsy publications and articles which met at least one of the inclusion criteria and not any of the exclusion criteria were selected. The inclusion criteria were: 1) assessment of the specificity of the biopsy, 2) assessment of system accuracy, 3) assessment of the biopsy results, and 4) duration of the procedure. Results: Only one article met all the inclusion criteria. Eleven articles that partially met the criteria were used for comparison. Authors used different stereotaxic methods and two used neuronavigation equipment. The authors of the stereotactic studies either adapted devices from human medicine or developed their own devices; the level of accuracy was variable (errors of 0.0 mm to 5.1 mm), and the two articles that used animals with spontaneous lesions had a diagnostic specificity rate higher than 90 percent. The accuracy of the neuronavigation studies was approximately 3.3 mm; however, no live animals were used. Conclusions: It was not possible to properly compare stereotactic and neuronavigation techniques. To do so, the methodologies and the assessed parameters need to be standardized.

Evaluation of ImageJ for Relative Bone Density Measurement and Clinical Application

Published on: 15th December, 2016

OCLC Number/Unique Identifier: 7286423139

The main method for evaluation of healing processes of the jaws in oral and maxillofacial surgery are radiological diagnostics. Quantitative description is possible by measuring the relative bone density, which puts the mean grey value of a certain area in relation to the surrounding bone tissue. In this research the intra- and interindividual variability is determined for this method and a standard operation procedure is elaborated. Therefore ten panoramic radiographs of typical surgical indications in oral a maxillofacial surgery were analyzed by three different members of the workgroup, five times each. The measurements were analyzed with descriptive and comparative statistical methods. The mean coefficient of variation was 2.972% ± 2.361%. The measurements of defect regions were more consistent (2.252% ± 1.928%) than the measurements of surrounding bone (3.691% ± 2.626%). The analysis of variance did not show a statistically significant influence of the different raters to the measurements (ANOVA, Pr>F = 0.9462). Following the standard operation procedure this method seems to be an easy, cheap and close to practice way to visualize healing process of the jaws. Especially in the mandibula, but also in the maxilla with special reconsideration of the sinus-region, it seems to be suitable.

Normal Value of Skull Base Angle Using the Modified Magnetic Resonance Imaging Technique in Thai Population

Published on: 20th March, 2017

OCLC Number/Unique Identifier: 7286350678

Purpose: To determine the normal value of basal angle measured using the modified MR imaging technique in Thai population compared with the standard value obtained from the Western population. Material and Methods: We retrospectively evaluated midline sagittal SE T1 weighted MR images in 200 adults and 50 children. The basal angle of the skull base was measured using the modified MR imaging technique described by Koenigsberg et al. The angle was formed by a line extending across the anterior cranial fossa to the tip of the dorsum sellae and another line drawn along the posterior margin of the clivus. The mean values of the basal angles among different age groups and sex were calculated and analyzed. Results: The mean skull base angle of our adult population was 115° (range 100.5°-130°, SD=5.7) with an inter-observer agreement of 0.85, slightly smaller than the previous study from the USA which was 117°. There was no significant difference between the male and female groups. The mean skull base angle in our children population was 114.7° (range 102- 130.5°, SD=6.3) with an inter-observer agreement of 0.89, quite similar to the previous USA study which was 114°. There was no significant difference between adult and children. Conclusion: The mean adult skull base angle measured using the modified MR imaging technique in Thai population was slightly smaller than the Western population, while the mean skull base angle of children was quite similar. The basal angle range of 103.6°-126.4° may be used as a guide for the potential range of normal skull base angles in Thai population and possibly also the Southeast Asian population.

Determinants of women’s perceived satisfaction on Antenatal care in urban Ghana: A cross-sectional study

Published on: 2nd July, 2019

OCLC Number/Unique Identifier: 8175476956

Despite evidence on major interventions on the uptake and scale up of interventions meant to promote maternal health care services, little is known about adequate use of such program in urban Ghana among reproductive aged women. This study examined the determinants of women’s Satisfaction on antenatal care use in selected health facilities in the Kwabre East Municipality of Ghana. Using facility-based cross-sectional survey design, a three-stage sampling technique was conducted to sample 220 women attending postnatal care at selected public health facilities. Open-ended questionnaires were used to obtain data from respondents. Descriptive statistics and inferential statistics including binary logit regression model were used to analyze the data with the help of SPSS and STATA software. Logit analytical framework was computed to determine equations of variance. The association between antenatal care use and women’s satisfaction was determined and assessed using Pearson’s χ2 (2) test indicating 1% was run. Most women (92.7%) had at least four ANC visits during their entire pregnancy. The results indicate standard deviation of 7 with 81% regular ANC visits and 19% irregular. Most women (55%) received care by one caregiver, followed by women (35%) who received care by two caregivers and women (10%) who were cared for by three caregivers. The regression results showed varying utilization levels of 10%, 5% & 1% ANC satisfaction. System induced factors aimed at promoting maternal care use satisfaction are suggested.

Twin-stage technique for occlusal rehabilitation of a mutilated dentition – A case report

Published on: 28th May, 2020

OCLC Number/Unique Identifier: 8627834705

Functional and aesthetic rehabilitation of an extremely worn dentition is one of the most challenging aspects of Prosthodontics. A thorough examination and diagnosis & selection of appropriate occlusal scheme are key factors to achieve optimal clinical outcome. Among the variety of techniques suggested in the literature, the twin-stage technique given by Hobo & Takayama has emerged as a popular choice for clinicians in recent times. Instead of the condylar path, it utilizes standard cuspal angle as the main determinant of articulation to produce predictable disocclusion in eccentric movements. It is relatively simple, does not require special armamentarium and can be incorporated easily with commonly used clinical techniques such as face bow transfer. The present case report describes the full mouth rehabilitation of a severely mutilated dentition using Hobo’s twin-stage technique to achieve a functionally and aesthetically favourable outcome.
