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.

Efficacies of 11% Lactoferricin and 0.05% Chlorhexidine Otological Solution compared, in the treatment of microbial otic overgrowth: A randomized single blinded study

Published on: 4th October, 2017

OCLC Number/Unique Identifier: 7325011971

Background:Topical therapy with antimicrobial agents is used in otitis treatment. Due to increase of antibiotic resistance, new strategies are needed. Antiseptics are used but they may induce contact dermatitis. Natural antimicrobial peptides may represent future effective drugs. Objectives:The objectives were to test the efficacy of an 11% lactoferricin otological solution (LCF) in bacterial and yeasts otic overgrowth and compare LCF with a commercial one containing chlorhexidine (CLX) 0.05%. Materials and methods:Forty-one dogs diagnosed with bacterial or yeasts otitis overgrowths were included according to general good practice. They were randomly assigned to lactoferricin or chlorhexidine group for treatment. Otological solution were applied twice a day for a week and then daily for another week. Clinical and cytological score was assessed at day 1 and day 14. At the end of the study, the owners had to express an opinion on the overall efficacy of the products. Statistical analyses were performed using Wilkoxon’s test and T test for paired samples. Results in lesional and cytological score were significative with a p<0.05. Results:Forty dogs completed the study. All cases, receiving lactoferricin or chlorhexidine, were successfully treated with clinical signs remission and regression of infection (p<0.05). The owners’ judgment was good in 87%, mild in 13% for LCF group. For CLX they scored good in 41%, mild in 24% and unuseful in 35% of cases. Conclusions:Lactoferricin, an antimicrobial natural peptide, showed the same efficacy of chlorhexidine in the treatment of otitis characterized by bacterial or/and yeast overgrowth.

Photon Absorption characteristics of some selected Enzyme Inhibitors used in Cancer Research in the Energy range 1 keV-100 GeV

Published on: 21st August, 2017

OCLC Number/Unique Identifier: 7286352738

The absorption parameters such as total mass attenuation coefficients, molecular, atomic, and electronic cross sections, effective atomic numbers and electron densities were calculated for some selected enzyme inhibitors in the photon energy range from 1 keV up to 100 GeV. The changes in the absorption parameters were interpreted with the photoelectric effect, Compton scattering and pair production processes. It is observed that the 2-Imino-1-imidazolidineacetic acid enzyme inhibitor has more radiation shielding feature when compared to other chosen enzyme inhibitors. The present investigation is anticipated to be useful for researchers studying with radiation in several fields and cancer researchers.

Comparison of two types of strengthening exercises in upper limbs for improvement of wheelchair propulsion in paraplegics

Published on: 10th February, 2017

OCLC Number/Unique Identifier: 7286422996

Introduction: A reduction in physical activity due to spinal cord injury leads to deconditioning and increased dependency. Manual wheelchair propulsion is a straining form of ambulation and propulsion is based on the use of upper extremities, which are usually capable of producing less force with less efficiency. Theraband can be an exercise mode, which resembles wheelchair activity. Mat exercises are also given for strengthening of upper limb muscles in persons with paraplegia. The aim of this study is to compare effects of both elastic resistance strength training and strengthening by mat activity of upper limb muscles on wheelchair propulsion efficiency in persons with paraplegia. Materials and Method: The selected subjects were randomly assigned into Theraband and Mat exercise groups with 15 subjects each. Theraband group received theraband strengthening of wheelchair propulsion muscles, whereas mat activity group received mat strengthening of wheelchair propulsion muscles. Total duration of treatment was 5 days per week for 5 weeks. Results: Results of the study showed both mat exercise and theraband groups showed significant improvement in wheelchair 15 meter sprint test and wheelchair propulsion for 50 meters in paraplegics due to spinal cord injury. However, theraband group showed significantly more improvement. Conclusion: The study revealed that theraband exercises for improving upper limb strength for wheelchair propulsion is superior to strengthening through mat exercise.

Time to Terminate LNT: Radiation Regulators Should Adopt LT

Published on: 26th June, 2017

OCLC Number/Unique Identifier: 7286353862

The linear no-threshold hypothesis (LNT)-the basis of radiation regulatory policy-extrapolates from observed high-dose harm to assumed low-dose harm, entailing that all ionizing radiation is harmful, by denying any biological response to damage and asserting cumulative lifetime harm, regardless of dose or dose rate. All aspects of LNT are demonstrably false. There are evolved biological responses that repair or remove radiogenic damage from low doses and dose rates, thereby averting acute harm and precluding the alleged cumulative damage. LNT and its offspring, the “as low as reasonably achievable” principle, do not err on the side of caution; neither is truly conservative. The public needs protection from radiophobia, rather than from low-dose radiation exposure. Neither radiation regulations nor medical practice should be based on LNT, but rather, at least as a first step, on a linear (down to a) threshold (LT) model.

Foot Arch Differences in Elderly People at Standing: Considering Gender and Age

Published on: 13th February, 2017

OCLC Number/Unique Identifier: 7286424220

Background: The foot is an important and complex structure that provides support, balance and propulsion to locomotion, thus, its proper care can help to have a better life quality avoiding pain. The medial longitudinal arch is an important structure that is related to injury risks when it shows some impairment. The purpose of this study was to characterize the foot arch index in people in relation to age and gender. Methods: The sample was composed of a total of 122 subjects, 79 healthy young subjects (40 women and 39 men) and 43 healthy elderly subjects (32 women and 11 men). Ten seconds of standing barefoot plantar pressure was measure through Tekscan F-Scan device, and the data processing, filtering, and arch index (AI) calculation were performed using MATLAB™ 7.0. Findings: The elderly group presented a lower arch (AI-0.23) than the young group (AI-0.13) (p=0.000); young female and male groups show similar AI, while the elderly female group showed lower arch (AI-0.23) than the elderly male group (AI-0.18) (p=0.033). Interpretation: The foot arch has a trend to be lower with aging, and even lower within elderly female subjects, probably due to some decrease within plantar muscle’s stiffness, that in turn may be related to lower physical activity and footwear choices.

Achilles Tendon Injuries: Comparison of Different Conservative and Surgical Treatment and Rehabilitation

Published on: 21st February, 2017

OCLC Number/Unique Identifier: 7286357861

Despite its high incidence and the great development of literature, there is still controversy about the optimal management of Achilles tendon rupture. The several techniques proposed to treat acute ruptures can essentially be classified into: conservative management (cast immobilization or functional bracing), open repair, minimally invasive technique and percutaneous repair with or without augmentation. Although chronic ruptures represent a different chapter, the ideal treatment seems to be surgical too (debridement, local tissue transfer, augmentation and synthetic grafts). In this paper we reviewed the literature on acute injuries.

Hypernatremia and central Diabetes Insipidus following Neurosurgical procedure of Trauma

Published on: 12th June, 2017

OCLC Number/Unique Identifier: 7317653928

The greater risk of hypernatremia in patients over 65 years old are associated with impaired mental status and physical disability which may result in impaired sensation to thirst, impaired ability to express thirst, and/or decrease access to water [1,2]. Normally, anti-diuretic hormone (ADH, also known as arginine-vasopressin, AVP) is secreted in response to 1-2% increase in osmolality which stimulate thirst, as do hypovolemia and hypotension.

Visualization and Evaluation of Changes after Rapid Maxillary Expansion

Published on: 30th March, 2017

OCLC Number/Unique Identifier: 7286430438

Objectives: The aim of the study was to develop a mathematical model for the visualization and evaluation of transversal palatal soft tissue changes; and to carry out a statistical evaluation of the changes in vertical and sagittal dimensions after rapid maxillary expansion treatment. Material and Methods: 33 Caucasian children with posterior crossbite, 10 boys and 23 girls, aged 7 to 10 years (median 8 years 8 months) were treated with tooth-borne Haas type expander. Dental casts were digitalized by scanner and on the basis of quantitative mesh shape CPD-DCA analysis, coloured morphometrical maps were created. The statistical significance of individual vertex displacements was calculated by performing Hotelling’s T2 paired test. To determine the significance of the vertical and sagittal profile changes, the paired t-test and Wilcoxon signed rank test were carried out in 20 patients Results: Visualization of the palatal soft tissue widening showed it to be greatest in the areas of the second deciduous and first permanent molars with maximum of 0.75 mm for each palatal side. Hotelling’s T2 paired test showed significant differences of p<0.01 in transversal width dimension. Cephalometric measurements of the changes to vertical and sagittal dimensions were statistically evaluated using the Wilcoxon and paired t-tests, and were shown to have insignificant values of p>0.05. Conclusion: The expansion appliance in children resolved the crossbite and led to palatal widening, which was clearly visualized by creating mathematical morphometric models. The cephalometric measurements carried out did not reveal statistically significant relevance in changes to facial vertical or sagittal dimensions.

Drawings as learning aid for the human anatomy students’ based evaluation

Published on: 5th October, 2017

OCLC Number/Unique Identifier: 7286428771

Introduction: One of the essential requirements for efficient oral and maxillofacial surgeon is comprehensive knowledge in anatomy of head and neck regions. Authors believe that asking students to draw anatomical sketches will assist them to improve their imaginary memory for human anatomy. However, drawing, as learning aid in anatomy, has not been given enough attention as a learning aid for human anatomy. Aim of the study: To determine dental students’ level of appreciation to drawings as practical learning aid in human anatomy. Materials and methods: Seventy nine first year dental students in Ibn Sina University for Medical and Pharmaceutical Sciences College of Dentistry for the academic year 2016-2017, were requested to complete a questionnaire. The questions were mostly related to the importance of drawing in anatomy and its relation to Anatomy education. The participation in the questionnaire was optional. Results: This study showed highly significant relationship between the ability to understand anatomy subject and the importance of drawing (P=0.006). It also showed highly significant relationship between the importance of drawings and giving clinical examples during lectures or anatomical labs (P=0.006). Furthermore, the results showed no significant relationship between the importance of drawings and the load of anatomical material, introduced in anatomical lectures and labs (P=0.639). Conclusion: Anatomical drawings, from first year dental students’ perspective, are a useful learning tool and can relate to different aspects of proper education of human anatomy. Drawings can be implemented as practical tool in human anatomy curriculum for undergraduate dental education.

Pathological Findings on Dental Panoramic Tomograms of Edentulous Patients Seen at a University Hospital

Published on: 19th April, 2018

OCLC Number/Unique Identifier: 7666273509

Objective: To describe pathological fi ndings on pre-treatment dental panoramic tomograms of edentulous jaws taken before complete denture treatment. Design: Descriptive cross-sectional study. Setting: Prosthetic division, Department of Conservative and Prosthetic Dentistry. School of Dental Sciences, University of Nairobi. Results: Data was obtained from clinical records and OPGs of 163 edentulous patients seen at the prosthetic clinic between 2010 and 2016 for complete denture therapy. From history and examination alone, clinicians reported significant findings on 50.3% of records, while 43.6% had no such findings. Ten (10) (6.1%) records were unclear. Examination of OPGs revealed 79.1% of the films had no pathological findings while in 20.9% had. Most of the findings (70.0%) were retained roots, 6% were radio-lucencies, 12% were other radio-opacities, 9% were impacted teeth while 3% had both retained root and radio-opacity. Most pathologies (64%) were located in the posterior region of jaws while the other findings were evenly distributed in the anterior and posterior regions of the jaws. There was no predilection of pathological findings to any other factor other than gender. In 83.4% records, queries on clinical notes coincided with significant findings on OPGs; while 16.6% were either unclear or did not coincide. Most (71%) OPG findings led to modification of treatment plan. Conclusion: Pathological findings are common on pre-treatment OPGs. It may be good practice to take an OPG for edentulous patients prior to complete denture therapy where such services are available, to prevent complications from intra-bony pathologies. However, Most of the findings are either detectable by clinical exam or may not be of major consequence to the health of patients. Complete denture may be done without OPGs for new and old denture wearers where the service is not available.

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.

Maternal mortality and factors affecting it, among pregnant women in Abeokuta South, Nigeria

Published on: 2nd July, 2019

OCLC Number/Unique Identifier: 8185504249

This observational study assessed the knowledge of pregnant women attending antenatal clinics at two selected hospitals in Abeokuta South, Nigeria on the causes and risk factors of maternal mortality, identified barriers to knowledge acquisition, and examined the influence of parity of respondents on their knowledge of factors causing maternal mortality. Maternal mortality is extremely high in Nigeria, it is defined as the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes. Descriptive research design was used in this study and qualitative data from 136 respondents selected randomly, were obtained through a self-designed questionnaire that comprised three sections. Data were analyzed and indicated that parity of the pregnant women do not have an influence on their knowledge of factors responsible for maternal mortality. Findings revealed that majority (67.6%) of the respondents had high knowledge on the causes of maternal mortality – haemorrhage, sepsis, prolonged/obstructed labour, anaemia, unsafe abortion, infection, hypertensive disorders, care rendered by unskilled medical practitioners and its risk factors - parity, poverty, place of last delivery and low attendance at antenatal clinic. Educational background, marital status, irregular antenatal visits, socio-cultural practices and occupational status were identified as barriers to knowledge acquisition. This paper concluded that pregnant women may have a high knowledge about the factors responsible for maternal mortality. This is probably due to the fact that all respondents had formal education and because they were interviewed on antenatal clinic days, which suggests that they might have heard about the causes and risk factors for maternal mortality during their visits. Authors recommended that government should employ qualified health professionals and provide medical subsidy, it is hoped that this will ensure that pregnant women get quality care throughout the period of pregnancy and delivery.

Quantification of the pressures generated during insertion of an epidural needle in labouring women of varying body mass indices

Published on: 1st December, 2017

OCLC Number/Unique Identifier: 7317597133

Objective: The primary aim of this study was to measure pressure generated on a Tuohy needle during the epidural procedure in labouring women of varying body mass indices (BMI) with a view of utilising the data for the future development of a high fidelity epidural simulator. High-fidelity epidural simulators have a role in improving training and safety but current simulators lack a realistic experience and can be improved. Methods: This study was approved by the National Research Ethics Service Committee South Central, Portsmouth (REC reference 11/SC/0196). After informed consent epidural needle insertion pressure was measured using a Portex 16-gauge Tuohy needle, loss-of-resistance syringe, a three-way tap, pressure transducer and a custom-designed wireless transmitter. This was performed in four groups of labouring women, stratified according to BMI kg/m2: 18-24.9; 25-34.9; 35-44.9 and >=45. One-way ANOVA was used to compare difference in needle insertion pressure between the BMI groups. A paired t-test was performed between BMI group 18-24.9 and the three other BMI groups. Ultrasound images of the lumbar spine were undertaken prior to the epidural procedure and lumbar magnetic resonance imaging (MRI) was performed within 72h post-delivery. These images will be used in the development of a high fidelity epidural simulator. Results: The mean epidural needle insertion pressure of labouring women with BMI 18-24.9 was 461mmHg; BMI 25-34.9 was 430mmHg; BMI 35-44.9 was 415mmHg and BMI >=45 was 376mmHg, (p=0.52). Conclusion: Although statistically insignificant, the study did show a decreasing trend of epidural insertion pressure with increasing body mass indices.

Correlation between the presence of maternal gestational or pre-gestational pathologies and hearing impairment in the puerperal period

Published on: 22nd November, 2019

OCLC Number/Unique Identifier: 8444358678

Objective: To evaluate whether the occurrence of maternal pathologies, mainly Diabetes Mellitus and Hypertensive Syndromes in the gestational or pre-gestational period may be related to hearing impairment in postpartum women. Methods: Observational, prospective study including 361 puerperal women who had their deliveries at a reference University Hospital for pregnant women with clinical history of risk. Auditory evaluation was performed by Distortion Product Otoaccoustic Emissions (DPOAE) within 14 days after delivery. Measures of central tendency and absolute and relative frequencies were used to describe the sample and the chi-square test and binary logistic regression to assess the correlation among variables. Significance higher than 95% was observed and the study was approved by the Research Ethics Committee. Results: A total of 361 postpartum women were studied and 7.5% had hearing impairment. The frequency of gestational hypertension was 13.9%, that of gestational diabetes was 8.6% and that of pre-pregnancy diabetes mellitus was 5.8%. The presence of hearing impairment was significantly correlated with the occurrence of pre-pregnancy diabetes mellitus (OR: 4.5 - CI: 1.51-1.47), and maternal age greater than 29 years (OR: 3.72 - 1, 58-8.76); A correlation was also found between maternal age and the presence of pre-pregnancy diabetes mellitus (OR: 3.84 - CI: 1.45-10.15). Conclusion: In the population of postpartum women evaluated, having Diabetes Mellitus prior to pregnancy and belonging to the age group older than 29 years increases the chance of having hearing loss.

Previous antibiotic treatment as a risk factor for recurrent vulvovaginal candidiasis

Published on: 3rd December, 2019

OCLC Number/Unique Identifier: 8444356881

The incidence of recurrent vulvovaginal candidiasis (RVVC) is extremely high. RVVC is likely to have a greater impact on patients. The aim of the study was to explore the risk factors of recurrent vulvovaginal candidiasis (RVVC) in the tropical coastal area. In this case-control study, a questionnaire survey was conducted in patients with VVC in the Sanya area from July 2014 to December 2016. The data included demographic characteristics, host factors, and behavioural characteristics. According to the maximum number of symptomatic episodes per year, the participants were classified into a non-recurrent VVC (NRVVC; < 4 episodes/year, including the current one) group or a RVVC group (≥ 4 episodes/year, including the current one). Crude odds ratios were calculated for potential risk factors and were adjusted using logistic regression. All vaginal secretions of patients with RVVC were cultured. Of the 728 cases of VVC, 69.0% (502/728) were NRVVC, and 31.0% (226/728) were RVVC. Previous antibiotic treatment (adjusted OR: 4.41, p < 0.01), repeat abortion (p < 0.05), and vaginal lavage (adjusted OR: 1.62, p < 0.05) were significantly associated with RVVC. A total of 230 yeasts isolates were obtained from 226 patients. C. albicans were the predominant Candida species (194 strains) in all patients of VVC. Our results demonstrate that in the tropical coastal area, a significant association was found between previous antibiotic treatment and incident RVVC. Host factors may be the most important factors in the occurrence of RVVC.

The incidence of hemodynamic and respiratory adverse events in morbidly obese presenting for Bariatric surgery

Published on: 25th July, 2018

OCLC Number/Unique Identifier: 7795943426

Context: Perioperative management of morbidly obese patients undergoing bariatric surgery is challenging. Lacking standardized perioperative protocols, complication rates may be high. This retrospective study aims to quantify the incidence of significant blood pressure decreases on induction of anesthesia and intraoperative hypoxemia, before implementation of a standardized protocol designed for bariatric surgery. Design: Retrospective, observational study. Setting: A 250-bed county hospital in northern Sweden. Subjects: 219 morbidly obese patients (body mass index > 35 kg/m2) who underwent bariatric surgery between 2003 and 2008. Main outcome measures: Incidence of systolic blood pressure (SAP) falls to less than 70% of the preoperative baseline during induction of anesthesia and incidence of perioperative hypoxemia. Results: The incidence of confirmed SAP falls to below 70% of baseline at induction of anesthesia was 56.2% (n = 123/219). This incidence rose with increasing age (p < 0.001) but not with body mass index (BMI). 3.7% (n = 8/219) of cases were marked as difficult intubations. A transient period of hypoxemia was observed in 6.8% (n = 15/219) and was more common with increasing BMI (p = 0.005). Fourteen different drug combinations were used in the study population. Of those administered an induction anesthetic drug, 72.6% (n = 159/193) were given an overdose when calculated by lean body weight, but this did not correlate significantly to SAP falls (p = 0.468). Conclusion: The incidence of a significant blood pressure fall upon induction of anesthesia was common. The incidence of airway and ventilation problems were low. Overdosing of anesthetics and excessive variation in applied anesthesia methods were found.

Assessing the Neurocognitive function effects of ketamine in Cardiac Surgical patients

Published on: 23rd October, 2018

OCLC Number/Unique Identifier: 7929258453

Background: Despite remarkable progress in surgical, cardiopulmonary bypass (CPB) and anesthetic tecniques, neurocognitive damage still remains an important cause of postoperative morbidity in cardiac surgery. The aetiology of neurocognitive damage is likely to be multifocal; including macro and microemboli, cerebral hypoperfusion, inflammation and nonpulsatile flow. N-methyl-D-asparticAcid (NMDA) receptors play an important role during neurocognitive damage. Ketamine is a non-competitive antagonist to the phencyclidine site of NMDA receptor for glutamate and directly suppresses proinflammatory cytokine production. The aim of the present study was to evaluate whether ketamine has neuroprotective effects during open-heart surgery through the use of neurocognitive tests. Methods: We considered all patients aged between 58-76 years who were referred to a single cardiothoracic surgical team for elective, primary coronary revascularization. Patients were excluded from the study for the following reasons: a history of neurological, psychiatric, gastrointestinal, hepatic, renal, hematologic and clotting systems disorder and repeat procedures. Undergoing CPB were randomized 2 groups: Group1 (ketamine)(n=25) or Group2 (propofol)(n= Patients 25) In the propofol group, anesthesia was induced with 3mg/kg propofol, 1µg/kg remifentanyl, 0.1mg/kg vecuronium. Remifentanyl 0.5-1μg/kg/min was infused intravenously throughout the whole procedure. In the ketamine group, anesthesia was induced with 1-2mg/kg propofol, 1-2mg ketamin, 0.1mg/kg vecuronium. Ketamin 1mg/kg/hour was infused intravenously. Pressors, inotropic agents and antiarrhythmics were used as needed. The Mini-Mental State Examination(MMSE) was administered the day before surgery and three days later. The change in scores for MMSE was calculated for each patient and all the group. The results were compared statistically with paired simple t-test. Results: The mean age, CBP duration, lowest temperature was not statistically significant (Table1). Peroperative and postoperative blood pressures and pulse rates showed differences between groups. There were no preoperative differences between the groups on any of the mean MMSE score (Table2). The ECG monitoring revealed that most patients remained in sinus rhythm, with no difference between groups. Conclusions: We could not demonstrate that intraoperatively administered ketamine resulted in greater neuroprotective effects compared with propofol. Ketamine in combination with propofol during cardiac surgery is associated with a stable hemodynamic profile. Propofol may reduce the delivery of microemboli to the cerebral circulation by decreasing the cerebral blood flow. Propofol has a direct neuroprotective effect in vitro, although Roach et al. could not demonstrate a protective effect of propofol during open-heart surgery. Propofol enhances the antiinflammatory response to surgery by several mechanisms. This might have masked a neuroprotective effect of ketamine because propofol was administered in both groups in our study.

OCLC Number/Unique Identifier: 8550958914

Background: Dysmenorrhea is menstrual disorder that affects about 40% - 90% of women worldwide, it is associated with oxidative stress. The current treatment of this condition is administration of non-steroidal anti-inflammatory drugs, which when frequently used, may affect organs. Objective: Assess the hepatotoxicity and nephrotoxicity side effects related to dysmenorrhea and its treatment Materials and methods: A survey (questionnaire) was designed and implemented on 689 female students of the University of Dschang. After this, and following the inclusion criteria, 191 blood samples were collected for assay of hepatotoxicity markers (transaminases, albumin), nephrotoxicity indicators (creatinine, urea, total protein) and the inflammation associated indicators. The measurements were performed on fully automated Olympus AU 400 Analyzer, using standard reagent kits. Results: Subjects with untreated dymenorrhea lasting more than five years had a significantly high level (p < 0.05) of ALT (39.47 ± 15.74 IU/L) and AST (44.37 ± 13.74 IU/L). Transaminases levels were significantly associate (p < 0.01) and positively correlate (0.251 for ALT and 0. 223 for AST) with the disease duration. Dysmenorrheic individuals on medication for more than 9 years had significantly higher ALT (25.14 ± 7.85 IU/L) and AST (35.26 ± 0.70 IU/L) levels (p < 0.05) compared to those under treatment for less than 5 years (19.37 ± 8.27 UI/L and 27.68 ± 8.56 UI/L). The use of analgesics, regardless of the duration of treatment, had normal creatinine clearance (107.44 ± 30.86 ml/min), compared to those treated with either anti-inflammatory drugs (71.56 ± 26.44 ml/min), or a combination of analgesics and anti-inflammatory drugs (81.34 ± 31.97 ml/min), which was significantly reduced (p < 0.05). Conclusion: Dysmenorrhea duration, type and duration of treatment potentially expose participants to liver and kidney disorders.
