    Clinical pulmonary surfactant is routinely used to treat premature newborns with respiratory distress syndrome, and has shown great potential in alleviating a number of neonatal and adult respiratory diseases. Despite extensive study of chemical composition, surface activity, and clinical performance of various surfactant preparations, a direct comparison of surfactant films is still lacking. In this study, we use atomic force microscopy to characterize and compare four animal-derived clinica...

    Full Text Available BACKGROUND Migraine is a common neurological problem accounting for large morbidity and disability. Ergotamine and triptans are mainly used to terminate the attack of severe migraine. To study the clinical comparison between sumatriptan and ergotamine in migraine patients. AIM This study compared the safety efficacy and pharmacoeconomics of triptans verses ergotamine therapy. MATERIALS AND METHODS Study sample included 100 patients of either gender aged 18 to 65 yrs reporting in Neurology OPD in Sapthagiri Institute of Medical Sciences, Bangalore. The study was conducted from January 2014 to December 2014. RESULTS Triptans was found to be more efficacious than ergotamine in curing an attack of migraine and its associated symptoms, but looking into the contraindications, side effects and cost of the triptans, there has been limitations in its prescriptions as well as use. CONCLUSION Ergotamine is more effective in sustained pain relief with less recurrence rate, less adverse effects and more economical compared to sumatriptan.

    Full Text Available Abstract Background The use of tolerogenic DCs is a promising therapeutic strategy for transplantation and autoimmune disorders. Immunomodulatory DCs are primarily generated from monocytes (MDDCs for in vitro experiments following protocols that fail to fulfil the strict regulatory rules of clinically applicable products. Here, we compared the efficacy of three different tolerance-inducing agents, dexamethasone, rapamycin and vitamin D3, on DC biology using GMP (Good Manufacturing Practice or clinical grade reagents with the aim of defining their use for human cell therapy. Methods Tolerogenic MDDCs were generated by adding tolerogenic agents prior to the induction of maturation using TNF-α, IL-β and PGE2. We evaluated the effects of each agent on viability, efficiency of differentiation, phenotype, cytokine secretion and stability, the stimulatory capacity of tol-DCs and the T-cell profiles induced. Results Differences relevant to therapeutic applicability were observed with the cellular products that were obtained. VitD3-induced tol-DCs exhibited a slightly reduced viability and yield compared to Dexa-and Rapa-tol-DCs. Phenotypically, while Dexa-and VitD3-tol-DCs were similar to immature DCs, Rapa-tol-DCs were not distinguishable from mature DCs. In addition, only Dexa-and moderately VitD3-tol-DCs exhibited IL-10 production. Interestingly, in all cases, the cytokine secretion profiles of tol-DCs were not modified by a subsequent TLR stimulation with LPS, indicating that all products had stable phenotypes. Functionally, clearly reduced alloantigen T cell proliferation was induced by tol-DCs obtained using any of these agent. Also, total interferon-gamma (IFN-γ secretion by T cells stimulated with allogeneic tol-DCs was reduced in all three cases, but only T cells co-cultured with Rapa-tol-DCs showed impaired intracellular IFN-γ production. In addition, Rapa-DCs promoted CD4+ CD127 low/negative CD25high and Foxp3+ T cells. Conclusions Our

    Full Text Available Diagnostic clinical prediction rules (CPRs are developed to improve diagnosis or decrease diagnostic testing. Whether, and in what situations diagnostic CPRs improve upon clinical judgment is unclear.We searched MEDLINE, Embase and CINAHL, with supplementary citation and reference checking for studies comparing CPRs and clinical judgment against a current objective reference standard. We report 1 the proportion of study participants classified as not having disease who hence may avoid further testing and or treatment and 2 the proportion, among those classified as not having disease, who do (missed diagnoses by both approaches. 31 studies of 13 medical conditions were included, with 46 comparisons between CPRs and clinical judgment. In 2 comparisons (4%, CPRs reduced the proportion of missed diagnoses, but this was offset by classifying a larger proportion of study participants as having disease (more false positives. In 36 comparisons (78% the proportion of diagnoses missed by CPRs and clinical judgment was similar, and in 9 of these, the CPRs classified a larger proportion of participants as not having disease (fewer false positives. In 8 comparisons (17% the proportion of diagnoses missed by the CPRs was greater. This was offset by classifying a smaller proportion of participants as having the disease (fewer false positives in 2 comparisons. There were no comparisons where the CPR missed a smaller proportion of diagnoses than clinical judgment and classified more participants as not having the disease. The design of the included studies allows evaluation of CPRs when their results are applied independently of clinical judgment. The performance of CPRs, when implemented by clinicians as a support to their judgment may be different.In the limited studies to date, CPRs are rarely superior to clinical judgment and there is generally a trade-off between the proportion classified as not having disease and the proportion of missed diagnoses

    Gliosarcoma (GSM) is a rare biphasic neoplasms of the central nervous system composed of a glioblastoma multiforme (GBM) admixed with a sarcomatous component. In clinical practice GSM is generally managed similarly to GBM. However, there are conflicting reports regarding their clinical aggressiveness, cell line of origin and possible prognosis compared with those of GBM. The objective of this study was to compare clinic-pathological features in GSM patients with the GBM patients during the same study period. 518 patients with GBM were treated at our hospital between 2008 and 2013, among them 51 were GSM. In this series the GSMs represented 9.8 % of all GBMs and included 58.8 % male with a median age of 44.7 years. The locations, all supratentorial, included temporal in 41.2 %, frontal in 25.5 %, parietal in 19.6 %, and occipital in 13.7 %. All patients underwent tumor resection followed by post-operative radiation and adjuvant chemotherapy. The O6-methylguanine-DNA methyltransferase promoter methylation studies were significantly more frequent in the GBMs than GSMs (80.1 % vs. 44.7 %, P GSM were 8.0 and 13.0 months, respectively, as compared with 9.0 and 14.0 months in the GBM group (log rank test P = 0.001 and 0.004, respectively). The Cox proportional hazards regression model indicated that the extent of tumor resection (HR = 1.518, P = 0.009) and pathological types (HR = 0.608, P = 0.002) were the significant prognostic factors in our own series. With regard to clinical features and outcomes, GSM and GBM cannot be distinguished clinically. GSM in China may be managed similarly to GBM, with maximal safe surgical resection followed by chemo-radiotherapy. Our study adds further evidence to support GSM as a unique clinical entity with a likely worse prognosis than GBM. PMID:26725096

    Full Text Available SUMMARY Objective: to determine the positive predictive value of clinical history in comparison with urodynamic study for the diagnosis of urinary incontinence. Methods: retrospective analysis comparing clinical history and urodynamic evaluation of 1,179 women with urinary incontinence. The urodynamic study was considered the gold standard, whereas the clinical history was the new test to be assessed. This was established after analyzing each method as the gold standard through the difference between their positive predictive values. Results: the positive predictive values of clinical history compared with urodynamic study for diagnosis of stress urinary incontinence, overactive bladder and mixed urinary incontinence were, respectively, 37% (95% CI 31-44, 40% (95% CI 33-47 and 16% (95% CI 14-19. Conclusion: we concluded that the positive predictive value of clinical history was low compared with urodynamic study for urinary incontinence diagnosis. The positive predictive value was low even among women with pure stress urinary incontinence.

    This study focused on identifying the best clinical learning model that would support nursing practice readiness following each immersion experience. Practicum preceptors completed surveys in which evaluated student preparation/readiness by assessing clinical knowledge, technical skills, critical thinking, communication, professionalism, management of responsibilities, and overall performance. The study results yielded no statistical significance when comparing both models. Future research is needed to analyze the impact of clinical hours offered in the senior immersion experience along with the curriculum content differences among various models of clinical experiences in undergraduate nursing programs to ensure practice readiness of nursing graduates.

    Periodicity of dental visits for children is based on age and disease susceptibility. Frequently mobile dental clinics are unable to provide follow-up care at recommended intervals. This study compared the oral health of children attending the mobile clinic (MC) twice with matched children by age, gender, race, and ZIP code attending for the first time. Dental charts (n=888) were reviewed and scored for decayed and filled surfaces. Seventy-eight children (mean age 9.6 years; 98.7% Hispanic) attended the clinic twice over a mean interval between visits of 1.5 years. These children had statistically significant lower rates of decay in deciduous and permanent tooth surfaces than matched children visiting the clinic for the first time (pdecay in their deciduous and permanent teeth than at the first visit (pdecay in teeth, even when the interval between visits is longer than current recommendations.

  11. Comparative study among calibration methods of clinical applicators of beta radiation

    International Nuclear Information System (INIS)

    90Sr+90Y clinical applicators are instruments used in brachytherapy procedures and they have to be periodically calibrated, according to international standards and recommendations. In this work, four calibration methods of dermatological and ophthalmic applicators were studied, comparing the results with those given by the calibration certificates of the manufacturers. The methods included the use of the standard applicator of the Calibration Laboratory (LCI), calibrated by the National Institute of Standards and Technology; an Amersham applicator (LCI) as reference; a mini-extrapolation chamber developed at LCI as an absolute standard; and thermoluminescent dosimetry. The mini-extrapolation chamber and a PTW commercial extrapolation chamber were studied in relation to their performance through quality control tests of their response, as leakage current, repeatability and reproducibility. The distribution of the depth dose in water, that presents high importance in dosimetry of clinical applicators, was determined using the mini extrapolation chamber and the thermoluminescent dosimeters. The results obtained were considered satisfactory for the both cases, and comparable to the data of the IAEA (2002) standard. Furthermore, a dosimetry postal kit was developed for the calibration of clinical applicators using the thermoluminescent technique, to be sent to clinics and hospitals, without the need of the transport of the sources to IPEN for calibration.

    Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance. The geographical distribution of P. aeruginosahas revealed the existence of an unbiased genetic arrangement in terrestrial isolates. In contrast, there are very few reports about P. aeruginosa strains from marine environments. The present work was aimed at studying the distribution of P. aeruginosa in coastal waters along the Indian Peninsula and understanding the environmental influence on genotypic, metabolic and phenotypic characteristics by comparing marine and clinical isolates. Of the 785 marine isolates obtained on selective media, only 32 (~4.1%) were identified as P. aeruginosa, based on their fatty acid methyl ester profiles. A low Euclidian distance value (< 2.5) obtained from chemotaxonomic analysis suggested that all the environmental (coastal and marine) isolates originated from a single species. While UPGMA analyses of AP-PCR and phenotypic profiles separated the environmental and clinical isolates, fatty acid biotyping showed overlapping between most clinical and environmental isolates. Our study revealed the genetic diversity among different environmental isolates of P. aeruginosa. While biogeographical separation was not evident based solely on phenotypic and metabolic typing, genomic and metatranscriptomic studies are more likely to show differences between these isolates. Thus, newer and more insightful methods are required to understand the ecological distribution of this complex group of bacteria. PMID:26413053

  13. A study comparing MRI with clinical examinations on wrists with rheumatoid arthritis

    International Nuclear Information System (INIS)

    Objective: To study the appearances of rheumatoid arthritis (RA) on MRI, and compare MRI with clinical examinations on wrists with RA. Methods: Fifty patients, fulfilled 1987 American Rheumatism Association (ARA) revised criteria, and 10 age-matched healthy controls entered the study. T1-weighted spin echo, short time inversion recovery (STIR) of both wrists, gadolinium contrast material-enhanced sequences of dominant wrists were performed in the coronal planes. MRl, plain wrist radiographs, clinical date, including swollen joint, patient global assessment (AIMS), and laboratory examinations including ESR, RF, APF, and AKA were obtained at the same time. Functional disability was assessed using the Health Assessment Questionnaire Disability Score. Results: In 50 patients, all had pannus on MRI of wrists, 38 patients had enhanced signal intensity for pannus, 21 patients had bone marrow edema, 37 patients had joint effusion, and 37 patients had bone erosions. There were significant difference in the ESR, HAQ, AIMS as well as swollen joint count between patients with bone marrow edema and patients without bone marrow edema (P2=5.06, P=0.025; χ2=5.59, P=0.018). Number of patients with MRI erosion of wrists was associated with the number of patients without MRI bone marrow edema of wrists (χ2=5.11, P=0.024). Conclusion: MRI can find the appearances of wrists with RA. Comparing MRI with clinical examinations on wrists with RA, authors can assess and evaluate the role of MRI on RA

    The magnetic resonance examination was performed in 38 patients with severe cerebral palsy (CP; 15 males and 23 females) who had both motor delay (unable to move anywhere) and mental retardation (I.Q. or D.Q. below 30). Neuroimaging findings were compared with the CP type, etiology, and grade of understanding of language. Cranial magnetic resonance imagings (MRI) in CP were divided into five types. In type 1, nine predominantly showed cyst-liked ventricles and periventricular hyperintensity on T[sub 2]-weighted imaging (PVH) and only scarred basal ganglia and thalamus were visible. All suffered from neonatal asphyxia and the clinical type was rigospastic tetraplegia (RST). In type 2, eleven predominantly showed PVH and hyperintensity on T[sub 2]-weighted (HT2) in basal ganglia and thalamus. All suffered from neonatal asphyxia and the clinical type was RST or rigospastic diplegia. In type 3, five showed PVH and three had cortical atrophy. All suffered from neonatal asphyxia and the clinical type was spastic diplegia. In type 4, four predominantly showed HT2 in putamen and thalamus. Three had cortical atrophy. All suffered from neonatal asphyxia. The clinical type was athetotic CP (ATH). In type 5, nine predominantly showed HT2 in globus pallidus. Four had cortical atrophy and two had hippocampal atrophy. All suffered from neonatal jaundice and the clinical type was ATH. All patients who suffered from neonatal asphyxia and spastic CP had MRI in PVH. All patients who suffered from neonatal asphyxia and ATH showed HT2 in putamen and thalamus. Almost patients who suffered from neonatal jaundice and ATH showed HT2 in globus pallidus. With athetotic CP, cases with atrophy of the cerebral cortex and/or hippocampus were lower grade of understanding of language than no atrophy of both. The results of studies of MRI are in agreement with neuropathological findings. (author).

    Topical tretinoin is the most commonly used retinoid for acne. However, its irritative potential on the applied area and the barrier properties of the stratum corneum limit its use. The objective of the present study was to formulate tretinoin liposomal gel to obtain a formula with lower skin irritation potential and greater clinical effect. A statistical 2(4) factorial design was adopted. Sixteen formulae prepared and were properly evaluated. A candidate formula (F13G) prepared with 0.025% tretinoin, phospholipid- cholesterol-dicetylphosphate (9:1:0.01) and incorporated in 1% carbopol gel was selected for skin irritation test. Clinical study was conducted on acne patients and compared to marketed product. All liposomes formulations were spherical in shape. The addition of cholesterol in the film hydration method significantly decreased the vesicle size, and increased the percentage of incorporation efficiency at (p acne patients revealed that F13G showed significantly higher efficacy when compared to marketed product (p < 0.05).

    Full Text Available Background: Clinically optimized focusing of drug administration to specific need of patient with bispectral index (BIS monitoring results in reduced dose and faster recovery of consciousness. This study was planned with an aim to study and compare the conventional clinical end point or BIS on the requirement of dosage of propofol, hemodynamic effects, and BIS alterations following propofol induction. Methods: 70 patients, ASA I and II, 20-60 years undergoing elective surgical procedure under general anesthesia with endotracheal intubation were selected and divided into two groups. Group A received (inj. fentanyl (2 μg/kg, followed 3 min later by inj. propofol at the rate of 30 mg/kg/hr infusion till the loss of response to verbal command while group B received inj. fentanyl (2 μg/kg, followed 3 min later by inj. propofol at the rate of 30 mg/kg/hr infusion. The end point of hypnosis was when the BIS value was sustained for 1 min at 48±2. The patients were intubated. Total induction dose of propofol was noted in each group. The value of BIS and hemodynamic parameters (heart rate, systolic/diastolic blood pressure were noted at the time of loss of consciousness, at the time of intubation, and 1 min after intubation, thereafter every minute for first 10 min and thereafter every 10 min till end of surgery. Any involuntary muscle activity such as jerky movements, dystonic posturing, and opisthotonos were also recorded. Results: The mean dose of propofol used in groups A and B were 1.85±0.48 mg/kg and 1.79±0.41 mg/kg, respectively. The dosage used in group B were less but not clinically significant (P=0.575. On comparing the dosage of propofol in males among the groups there was a significantly lower dosage of propofol required in group B (2.06±0.45 mg/kg and 1.83±0.32 mg/kg, respectively, P=0.016. This decrease however was not seen in female patients dosage being 1.65±0.44 mg/kg and 1.75±0.49 mg/kg, respectively (P=0.372. The hemodynamic

    International Nuclear Information System (INIS)

    Objective: To compare the clinical, high-resolution computed tomography (HRCT) and pathological findings of primary alveolar proteinosis (PAP) and silicoproteinosis. Material and methods: The study included 15 patients with PAP (6 women, 9 men, mean age 31 years) and 13 with silicoproteinosis (13 men, mean age 29.5 years). PAP was diagnosed by lung biopsy in 13 and bronchoalveolar lavage in two patients and silicoproteinosis by bronchoalveolar lavage in 10 and autopsy in three cases. HRCT images were reviewed by two chest radiologists with consensus for the presence, extent and distribution of ground-glass opacities, septal thickening, consolidation and nodules. Radiological–pathological correlation was performed by one radiologist and one chest pathologist. Results: Seven (46%) patients with PAP were asymptomatic; the remainder presented slowly progressive dyspnea and dry cough. All silicoproteinosis patients had dry cough and rapidly progressive dyspnea. The most common HRCT finding on PAP was the crazy-paving pattern (93%). All cases had areas of geographic sparing in the affected lung. The most common finding in silicoproteinosis (92%) was dependent consolidation with calcification in 83%. Centrilobular nodules were common (85%). On pathology, both diseases demonstrated intra-alveolar accumulation of PAS material, thickening of interlobular septae and alveolar walls and no evidence of fibrosis. A few silica particles were seen in silicoproteinosis. Conclusion: Despite the pathological similarities, PAP and silicoproteinosis have distinct clinical and imaging features and prognosis. Bilateral crazy-paving pattern with areas of geographic sparing is characteristic for PAP. Silicoproteinosis presents with bilateral dependent consolidation often with areas of calcification. The crazy-paving pattern is not seen in silicoproteinosis.

    Full Text Available Abstract Background Indigenous Australians are a small, widely dispersed population. Regarding childbearing women and infants, inequities in service delivery and culturally unsafe services contribute to significantly poorer outcomes, with a lack of high-level research to guide service redesign. This paper reports on an Evaluation of a specialist (Murri antenatal clinic for Australian Aboriginal and Torres Strait Islander women. Methods A triangulated mixed method approach generated and analysed data from a range of sources: individual and focus group interviews; surveys; mother and infant audit data; and routinely collected data. A retrospective analysis compared clinical outcomes of women who attended the Murri clinic (n=367 with Indigenous women attending standard care (n=414 provided by the same hospital over the same period. Both services see women of all risk status. Results The majority of women attending the Murri clinic reported high levels of satisfaction, specifically with continuity of carer antenatally. However, disappointment with the lack of continuity during labour/birth and postnatally left some women feeling abandoned and uncared for. Compared to Indigenous women attending standard care, those attending the Murri clinic were statistically less likely to be primiparous or partnered, to experience perineal trauma, to have an epidural and to have a baby admitted to the Neonatal Intensive Care Unit, and were more likely to have a non-instrumental vaginal birth. Multivariate analysis found higher normal birth (spontaneous onset of labour, no epidural, non-instrumental vaginal birth without episiotomy rates amongst women attending the Murri clinic. Conclusions Significant benefits were associated with attending the Murri clinic. Recommendations for improvement included ongoing cultural competency training for all hospital staff, reducing duplication of services, improving co-ordination and communication between community and tertiary

    Full Text Available The Bactigras® paraffin tulle coated with chlorhexidine is normally used for the treatment of donor-site wounds in burn patients who received split-thickness skin grafts in several centers. It has some disadvantages, such as adhesion to wound surfaces and pain from the irritation caused by this dressing. The Telfa AMD®, a non-adherent wound dressing which consists of absorbent cotton fibers impregnated with polyhexamethylene biguanide enclosed in a sleeve of thermoplastic polymers, is a new option for donor-site wound care which causes less adherence to the wound. The purpose of this study was to compare clinical efficacy of these two dressings for the management of donor-site wounds. Thirty-two patients who received split-thickness skin grafts by donor site harvesting from the thigh were enrolled in this study and randomized into two groups receiving either the Bactigras® or the Telfa AMD® wound treatment. Re-epithelialization, pain, infection and cost-effectiveness analyses were compared between both groups. The results showed that there was no significant difference in age, area of donor sites or length of hospital stays between the groups (p > 0.05. However, the day of re-epithelialization (≥90% was significantly shorter in patients treated with the Telfa AMD® compared to the Bactigras® group (14.00 ± 3.05 vs. 9.25 ± 1.88 days for Bactigras® and Telfa AMD® groups, respectively, p < 0.001. The average pain score was also significantly lower in the Telfa AMD® group (1.57 ± 0.55 vs. 4.70 ± 1.16, p < 0.001. There was no difference in the cost of treatment between the groups (4.64 ± 1.97 vs. 5.72 ± 2.54 USD, p = 0.19. This study indicated that the Telfa AMD® was an effective dressing for the treatment of donor-site wounds.

    Full Text Available Introduction:- Regional analgesia provides excellent pain relif in labour. This study was designed to compare combined spinal eqidural (CSE versus epidural block using a narcotic (sufentanil and local anaesthetic bupivacaine regarding their effects on progress of labour, method of delivery, pain relif, side effects and neonatal outcome. Patients and Methods :-Forty pregnant women ASA I and II were enrolled in this study. The women were randomly allocated to receive either CSE or epidural ( 20 patient of each . In CSE group analgesia was initiated with 10ug sufentanil with 2mg bupivacaine. In epidural group 10ml bupivacaine 0.125%.and 10ug sufentanil injected epidurally. In both groups the continuous infusion of 0.83% bupivacaine with 0.33ug/ml sufentanil at 10ml/hr adjusted as required. Maternal haemodynamics, analgesia characteristics VAPS, degree of motor block, were measured. Duration of labour, cervical dilation, maternal satisfaction and mode of delivery were assessed. Foetal outcome was assessed by 1 and 5 min. Apgar score and umbilical venous blood gases. Maternal and neonatal side effects were observed. The experimental study was done on 30 rats divided into 3 groups 10 rats of each. Control group (A injected intrathecally with saline, group (B injected intrathecally with 1.5ug/kg sufentanil (low dose, and group (C injected intrathecally with 7.5ug/kg sufentanil (high dose, the pervious doses were injected every 2hr. for 3 times then the spinal cord was obtained and stained for histological evaluation. Results:- The clinical study showed that no difference between the 2 groups for the degree of motor block or adequacy of analgesia, mode of delivery and Foetal outcome. The onset of analgesia was faster with CSE technique, more patient satisfaction and more pruritis. The histological results revealed that no detectable significant neurotoxic changes with the use of small dose of intrathecal sufentanil but mild changes occurred with high

    Full Text Available In 2002, after analyzing 28 HIV-positive patients with movement disorders we emphasized the decreasing not only of Parkinsonism but also of other involuntary movements in HIV patients in the last few years. The objective of this study is to compare the clinical results between HIV-positive patients with Parkinsonism before and after HAART. In 14 years (1986-1999 2,460 HIV-positive patients were seen in our Hospital 14 (0.6% of which presented with Parkinsonism. Eight years after (2000-2007 970 HIV positive patients were seen and only two (0.2% had Parkinsonism.

Both these remedies proves extremely beneficial as it can be performed on the OPD & IPD basis, gives significant relief in the symptoms e.g. radiating pain, stiffness, twitching sensation. The subjective parameters like Pain, SLR, VAD, VDS etc., were used to score clinical outcome. The average clinical improvement was calculated by proper statistical treatment. Our experience with this modality has been encouraging as the response pattern is good in considerably short duration of treatment. The patient improves gradually after 4 weeks of treatment. The pain relief provided by Agnikarma & sustained improvement with Basti presents a window of opportunity in the clinical management of Sciatica. Ideally this technique should be practically taught to the physicians and should be evaluated scientifically using principles of biophysics and nerve conduction studies.

    Full Text Available Introduction: Menopause means complete stoppage of menses for last one year due to failure of follicular activities of the ovaries. This can be determined by the various hormones secreted by ovary such as LH and FSH. As these hormones are responsible for normal maintenance of basic ovarian function in reproductive life; there occurs considerable alteration in their levels in menopause. Aims and Objectives :- 1] To study and compare ovarian function by determining levels of LH and FSH in Surgical and Natural menopause. 2] To study and compare ovarian function in Surgical and Natural menopause. Brief Methodology: – Case study: - 50 women with surgical menopause between 45 – 50 years of age. Control study: – 50 women with natural menopause between 45 – 50 years of age. Material & Methodolgy :- Fasting serum samples of all women with surgical and natural menopause were analysed for LH and FSH on Immulite 1000 chemiluminiscence based analyser in special investigation lab. Summary of the Results:- Mean levels of LH and FSH were higher in surgical menopausal women as compared to natural menopausal women. Women in surgical menopause suffered from more vasomotor symptoms and cognitive decline as compared to women in natural menopause group

  6. Muscle lesion comparing of imaging procedures (sonography and MRT) -experimental and clinical study

    International Nuclear Information System (INIS)

    Muscle injuries in sports are more common now. Diagnosis and follow up of muscle injuries is nowadays achieved by sonography and MRT. In order to assess the two imagine procedures, a direct test for comparison of sonography and MRT was performed in an experimental study: A standardised disconnection of m. triceps surae in rats was either sutured and glued or not treated. Clinical studies were performed in 26 patients suffering from muscle trauma. Sonography was proved to be a reliable procedure especially in follow up control until full weight bearing and should be used first. Negative or doubtfull findings require further investigation by MRT. Especially contrast medium (Gd-DTPA) assisted examinations enables a long term follow up and may even show small (muscle strain) and deep lying injuries. (orig.)

    Considering several clinical situations, low intensity laser therapy has been widely applied in pain relief or analgesia mechanism. With the advent of new LED-based (light emitting diode) light sources, the need of further clinical experiments aiming to compare the effectiveness among them is paramount. The LED system therapeutic use can be denominated as LEDT - Light Emitting Diode Therapy. This study proposed two clinical evaluations of pain relief effect: to dentin hypersensitivity and to cervicogenic headache using different sources of lasers (low and high intensity) and light emitting diodes (LEDs), one emitting at the spectral band of red (630+/- 5nm) and the other one at infrared band (880+/- 5nm). Two different clinical studies were performed and presented interesting results. Considering dentin hypersensitivity, red and infrared led were so effective than the control group (high intensity laser system); by the other side, considering cervicogenic headache, control group (infrared laser) was the best treatment in comparison to red and infrared led system.

    Full Text Available Aim: The aim of the presented study is to compare the effectiveness of the diagnosis with a dental microscope, laser fluorescence (DIAGNOcam and X-ray examination in proximal caries diagnosis. Material and methods: Thirty-eight adult patients were examined. They were first examined with a dental mirror and a probe, under magnification 6.4 times. After that a diagnosis with DIAGNOcam was performed. Bitewing X-ray images were administered. The data from the three diagnostic methods was compared using SPSS 16 package of Windows. The lesions that were diagnosed as involving dentin were then excavated which served as a confirmation of the diagnosis. Results: The results of the study showed that dentinal lesions were detected with a high degree of correlation with all three diagnostic methods. The visual examination seriously underestimated lesions involving only enamel. In these cases there was a good correlation between laser fluorescence and X-ray data. Conclusions: Based on the conducted study we could conclude that the diagnosis of proximal caries with DIAGNOcam is equivalent to X-ray, both being more accurate in cases with early lesions, compared to visual diagnosis.

    The importance of correlating anatomical studies with diagnostic and therapeutic approaches in practice has long been recognised. Such studies in the horse have, until recently, lagged behind this discipline in human medicine and surgery. Clinical techniques by which this correlation is achieved include radiography, ultrasound, computed tomography and magnetic resonance imaging. This review presents published literature on the subject and, in addition, describes the part played by plastination, a recently developed technique for the preservation of biological specimens. In this, tissue fluids and part of the lipids are replaced by certain polymers yielding specimens that can be handled without gloves, do not smell or decay, and even retain microscopic properties of the original sample. The technique has proved to be a useful tool to correct previously presented anatomical descriptions and is one now favoured by human surgeons. Studies of the horse employing this technique include those of the temporomandibular joint and tarsus. The aim of the review is to stimulate further correlations of anatomical structure and equine medical and surgical procedures, thereby advancing knowledge and understanding in practice and teaching.

    Full Text Available Research objective is to study antibacterial action of nanoparticles of iron and copper on polyantibiotically resistant clinical Staphylococcus aureus strains. Materials and methods include antibacterial action of nanoparticles of copper and iron on 10 Staphylococcus au¬reus strains, isolated from patients with purulent complications stayed in the in-patient department of traumatology and orthopedics. Solutions of powders of iron and copper have been prepared directly before the experiment in concentra¬tion from 0,001 to 1 mg/ml. it has been revealed that the influence of nanoparticles on growth of clinical strains and the intensity of antibacterial effect depends on the form of nanoparticles, their concentration and action time. concentration of 0,1 mg/ml and 1 mg/ ml of iron nanoparticles has provoked the decrease in quantity of microbe cells from 3 to 34 % (p <0,01. in smaller concentrations the reliable antibacterial effect has not been observed. Antibacterial activity of copper nanoparticles has been expressed in a wide range of concentrations from 0,001 mg/ml to 1 mg/ml, even during short-term action (30 minutes it has provoked reduction of quantity of the microbe cells grown on the firm nutrient medium, 97-100 % in comparison with the control (p <0,001. in conclusion it is to point out that copper nanoparticles have more expressed inhibitory effect on growth of clini��cal strains of golden staphylococcus than iron nanoparticle suspension. inhibition degree depends on superdispersed powder dosage and incubation period

    International Nuclear Information System (INIS)

    Dentin hypersensitivity is a common condition associated with high dental pain. A new LED-based (light emitting diode) light source has been used as an experimental tool in some studies. Purpose: The main objective was to compare these two light sources emitting in the same spectral band (red – from 625 to 660 nm) to promote pain relief. Material and methods: A total of 6 sessions were accomplished, being three irradiation sessions and three follow-up sessions. This single-blind study compared a control group (Placebo) and two other groups with different equipments: low laser intensity treatment (LILT) and a light emitting diode system treatment (LEDT). Results: The results showed that there is no statistical difference between LILT and LEDT groups, however, both were better than control group (p ≤ 0.01) in terms of treatment efficiency; there is no difference between the second and the third sessions for both treatment, it means that the third session was not necessary; finally, the improvement at the end of the entire research (follow up care of 30 days) was very expressive in comparison to pre-treatment situation for all teeth (p ≤ 0.01). Conclusion: LILT and LEDT were equally effective to treat dentine hypersensitivity, a 3rd treatment session was not necessary/two sessions are enough

  14. Percutaneous vertebroplasty and conservative therapy for osteoporotic vertebral compression fractures: a clinical comparative study

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical efficacies of percutaneous vertebroplasty and conservative therapy in patients with osteoporotic vertebral compression fractures. Methods: One hundred and four vertebrae in 83 patients with osteoporotic compression fractures were shown by MRI, CT and plain radiography. Forty four patients with 58 vertebrae were assigned to group 1 treated by PVP, and 39 patients with 46 vertebrae were assigned to group 2 treated by conservative therapy. The efficacies of two groups were evaluated by measuring the heights of vertebrae on the lateral plain films during follow-up. Results: No serious complications occurred with PVP. Pain relief was obtained in all of 44 patients and VAS score decreased from 8.5 before the procedure to 2.6 at 1 week after PVP(improvement of 5.9). Pain still remained in all 39 patients at 1 week after conservative treatment. Improvement was significantly greater in the group 1 than in group 2 at 1 week, 1 month and 3 months, but no difference at 6 months after treatment (P>0.05). Within 8.9 months of mean follow-up, 3 new fractures occurred in 3 patients in group 1, 2 new fractures occurred in 2 patients in group 2, showing no significant difference. The average increase in vertebral body height on the X-ray plains at 1 week after PVP was 2.2 mm anteriorly, 2.3 mm centrally and unchanged posteriorly. Comparing with the plain film at 1 week after PVP, the heights of vertebrae showed no significant difference at 3 and 6 months of follow-up respectively the heights of vertebrae were unchanged at 1 week after conservative therapy. Average reduction in vertebral body height was 1.9 mm anteriorly, 2.1 mm centrally, unchanged posteriorly at 3 months, but no more collapse at 6 months after conventional treatment. The vertebral body height was significantly higher in the group 1 than in group 2 at 3 months after treatment. Conclusions: PVP is an effective and safe procedure for treating persistent painful osteoporotic

    Full Text Available Allergic contact dermatitis is becoming a common skin problem all over the world. It accounts for about 4-7% of all dermatological problems. This is due to a delayed hypersensitivity reaction following contact with antigens. Hypersensitivity to chemicals appears to become a serious health problem for the general population, particularly in their work environment it will be the most incapacitating condition as a consequence of skin being exposed to chemical agents. Allergic contact dermatitis is characterized by erythema, scaling, edema, vesiculation and oozing. Itching varies from mild to severe. These features can be correlated with vicharchika. So in order to manage vicharchika in terms of Allergic contact dermatitis, a comparative study was done to evaluate the effect of virechana and shamanaushadhis. Group A was given virechana followed by shamanoushadhis i.e., Laghu sootashekara vati and Nava kwatha along with Manjishtadi taila for external application for 30days. Group B was given only shamanoushadhis for 30 days. The efficacy of the treatment was assessed by noting the prime lakshanas of vicharchika like shyava varna, pidaka, kandu and srava before and after the treatment and statistically analysed using student ‘t’ test. After treatment it is observed that, both shodhana chikitsa and shamana chikitsa have their own role in the management of vicharchika. Even statistically, both are having highly significant values within the individual groups. But when both shodhana and shamana treatment are statistically compared, they show no significant values which means that both are effective with no significant difference between them.

Herein we compared the clinical features of GBS between pediatric and adult patients.We retrospectively collected the clinical data of 750 patients with GBS (541 adults and 209 children, and compared the clinical characteristics between children and adults.Pain was a more frequent complaint in children (17.2% vs 9.6%, p 0.05. The clinical features of acute motor axonal neuropathy (AMAN and acute inflammatory demyelinating polyneuropathy (AIDP in children were overall comparable with adult ones (p > 0.05. Similar to adults, bulbar dysfunction (odds ratio [OR]: 4.621, 95% confidence interval [CI]: 1.240-17.218, p < 0.05 and lower nadir Medical Research Council (MRC sum score (OR: 0.897, 95% CI: 0.855-0.941, p < 0.01 were also risk factors for mechanical ventilation in children. However, distinct from adult ones, autonomic dysfunction was significantly higher in mechanically ventilated childhood GBS (39.1% vs 8.8%, p < 0.01, which also served as a predictor for mechanical ventilation in pediatric GBS (OR: 70.415, 95% CI: 9.265-535.158, p < 0.01. As to the efficacy of intravenous immunoglobulin, insignificant difference was identified between children and adults.The clinical features of pediatric GBS differ from those of adults. Autonomic dysfunction is an independent risk factor for mechanical ventilation in pediatric patients.

  17. Comparative study on cases of vertigo and dizziness in the emergency room and otorhinolaryngological clinic

    International Nuclear Information System (INIS)

    We recently studied the characteristics of vertigo and dizziness in 197 patients who first visited the emergency room (ER group) and in 288 patients who first visited the otorhinolaryngological clinic of Minoh City Hospital (ENT group) between January 1 and December 31 of 2009. The ER group can be regarded as representing the hyperacute phase and the ENT group as representing the acute to chronic phase. These two groups were completely distinct. We also subdivided these groups into the high risk subgroup (H subgroup) for cases with the underlying diseases of diabetes mellitus, hypertension, cerebrovascular disease and hyperlipidemia, and the normal subgroup (N subgroup).Comparison of the two groups showed that, in the ER group, a significantly larger numbers of patients had symptoms of peripheral vestibular origin except for benign paroxysmal positional vertigo (BPPV) and Meniere's disease, and a significantly larger number of patients had symptoms of unknown origin in the ENT group. Half of this group may be accounted for by patients with symptoms of peripheral vestibular origin except for BPPV and Meniere's disease in the ER group. In 8 out of 158 patients of the ER group and 1 out of 122 patients of the ENT group, cerebral lesions were not found on CT images but were found with MRI. Careful investigation is necessary in the patients with normal CT findings. Central vestibular lesions were found in 7 out of 197 patients (3.5%) of the ER group and 5 out of 288 patients (1.7%) of the ENT group. The incidence of central lesions tended to be higher in the ER group than in the ENT group. There was no significant difference in the incidence of central lesion among the H and N subgroups of both groups. Careful investigation of the central vestibular lesion is also necessary in the N subgroup. (author)

    Retrospective analysis of cholescintigraphy and ultrasonography was done in 76 patients with clinically suspected acute cholecystitis to assess the relative value of the two modalities. Excluding the patients with obstructive jaundice, the overall results of cholescintigraphy(sensitivity 100%, specificity 95%, false positive rate 5%, false negative rate 0%, accuracy 97%) are nearly identical with or rather superior to those of the ultrasonography(sensitivity 94%, specificity 100%, false positive rate 0%, false negative rate 5%, accuracy 97%). We recommend the cholescintigraphy as the initial modality in patients with clinically suspected acute cholecystitis, and ultrasonography can be used in jaundiced patients to exclude the possibility of the false positive of cholescintigraphy.

[Subjects and Methods] This study included seventy-eight cases of congenital dysplasia of the hip (I-III type). Furthermore, four parameters were measured, including the preoperative and postoperative femoral offset. Statistical data analysis was performed using the SPSS 13.0 software. [Results] The femoral offset was 33.3 ± 8.4 mm (preoperative) and 39.1 ± 7.1 mm (postoperative). The femoral head height was 59.5 ± 8.7 mm (preoperative) and 68.8 ± 11.0 mm (postoperative). The femoral neck length was 50.8 ± 10.8 mm (preoperative) and 61.5 ± 10.4 mm (postoperative). The hip abductor arm was 54.3 ± 9.6 mm (preoperative) 64.7 ± 10.1 mm (postoperative). The preoperative and postoperative parameters showed statistical differences. Furthermore, no significant differences were evidenced when comparing the postoperative hip parameters with the normal data parameters. [Conclusion] Total hip replacement on congenital dysplasia of the hip could lead to the rebuilt of an almost normal physiological anatomy for each hip case (type I-III). PMID:27512242

    International Nuclear Information System (INIS)

    Poly-L-lactide (PLLA) is one of the most used polymers for biomedical application; its use in sutures and other implants has been widely investigated. Although the knowledge of PLLA biodegradation and biocompatibility features is deep, PLLA screws used to correct the flat foot deformity have deserved attention since they are not degraded in most of cases after a long period of years (3–7) from the implantation. In this article, a clinical and radiological evaluation (NMR, histological and clinical outcomes) on patients was correlated with physico-chemical characterization (by SEM, DSC, GPC and XRD analysis at different temperatures) on both native and patient-recovered screws together with the theoretical degradation processes of PLLA-based implants. The data demonstrated the need for crossing the biodegradation and bioabsorption of the polymer with the characteristics of both the device (geometry, structure and fabrication process) and the implantation site. Highlights: ► Resorbable PLLA screws were proposed for arthroereisis in pediatric flatfoot. ► Satisfactory clinical results were obtained almost in the totality of patients. ► The bioabsorption period is slightly longer than what is expected. ► Patient-recovered screws were analyzed to evaluate the biodegradation stage. ► Degradability/structural integrity during implantation should be ameliorated

    Background: Elevation of the neutrophil to lymphocyte ratio (NLR) has been shown to be an indicator of poor prognosis in many malignancies including recurrent glioblastoma multiforme. Objectives: This study was aimed at assessing if the NLR and other leukocyte counts and indices were deranged in treatment-naïve patients with primary brain tumors when compared with an age-matched healthy control group. Materials and Methods: This was a prospective comparative clinical observational study by design. A healthy control population was compared with treatment-naïve patients diagnosed with intra- and extraaxial brain tumors. Leukocyte counts (neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts) as well as leukocyte ratios such as the NLR and the monocyte to lymphocyte ratio (MLR) were calculated. We also evaluated if the counts and indices were related to the tumor volume. Results: In all patients with tumors, the platelet and neutrophil counts were elevated when compared to the controls. In contrast, monocyte counts and the MLR were found to be decreased in patients with tumors when compared to the controls. The subset of patients with glioblastoma showed a significant increase in NLR when compared to the controls. Conclusions: Significant changes in the neutrophil, monocyte, and platelet counts as well as NLR and MLR were observed. Prospective longitudinal studies are required to determine the prognostic and therapeutic implications of these findings. PMID:27089106

    1998-01-01

    Fifty nine asthmatic children and adolescents, clinically stable, aged 6 to 15 years, 37 boys and 22 girls, from Instituto da Criança do Hospital das Clínicas da FMUSP, were studied from September to November, 1994. The patients were classified by the clinical score of the International Consensus for Asthma Diagnosis and Management. They performed baseline spirometry and peak expiratory flow rates (PEFR), before and after bronchodilator, and measured PEFR three times a day (6 pm, at bedtime and on waking), for one day, at home. Five PEF measurements were made serially and the best readings were considered. Variability of PFE was calculated for 24 hours, as assessed by maximal amplitude. The results were summited to statistical analysis of the Laboratorio de Informática Médica da Faculdade de Medicina da USP. The results of PEFR and it's variability were compared to spirometry, (functional score, FEV1-forced expiratory volume in the first second) and to the clinical score of the International Consensus for Asthma Diagnosis and Management. In case of disagreement between the clinical parameters, the more severe one was chosen. The clinical score classified 20.3% of our patients as mild obstruction, 49.2% as moderate and 30.5% as severely compromised. According to FEV1, 58% of patients were classified as normal while the PEFR and its variability classified as normal 76% and 71%. The PEFR and it's variability in 24 hours, correlated with the VEF1, as gold standard, showed good specificity, 91% and 76% respectively and low sensibility, 44% and 32%. It was detected a low level of agreement between FEV1, PEFR and it's variability in 24 hours, in the clinical severity classification of asthma. The results of this study showed that FEV1 and PEFR had a low level of agreement in the clinical severity classification of asthma and when they were correlated to the clinical score of the International Consensus, they both presented low sensitivity.

    Full Text Available Aim: This study aimed to investigate the existence of the golden proportion, recurring esthetic dental (RED proportion and golden percentage between the frontal view widths of the maxillary anterior natural dentition among students of Indian origin by the aid of digital photography. Materials and Methods: This study was conducted with 80 dental students (41 female and 39 male, with ages ranging from 20 to 23 years. Students whose natural smile did not develop any visual tension with regard to the study′s and their own criteria were selected as having an esthetic smile. Photographs were taken, and the mesiodistal widths of six maxillary anterior teeth were measured digitally using software. Once the measurements were recorded three different theories of proportion were applied and statistical analysis was done. Results: The golden proportion, i.e., 62% RED proportion and golden percentage were not observed in the subjects. According to the subjects evaluated, the average width of the maxillary lateral incisor was 72% of the frontal view width of the central incisor. The average width of the canine was 84% of the frontal view width of the lateral incisor. Conclusion: The golden proportion and RED proportion were not observed in the natural smiles of subjects who were deemed to have an esthetic smile. The values proposed for the golden percentage theory were not observed in subjects with an esthetic smile. Average frontal view percentage widths of the maxillary anterior dentition exist and can be useful in predicting naturally occurring widths in smiles deemed to be esthetic in a specific population.

    Full Text Available Background: Tinnitus is one of the otologic symptoms commonly reported to be associated with temporomandibular disorder (TMD, and questions regarding its nature and cause continue to plague the clinical and research community.Objectives: The current pilot study aimed to investigate the clinical signs and symptoms of presenting tinnitus in a group of individuals with TMD (group A, and compare them with a group with tinnitus but without TMD (group B. Twenty participants were included in the study, 10 from each group.Methods: All participants underwent basic audiological as well as ear, nose and throat (ENT evaluations to establish group A and group B. For tinnitus assessment, all participants completed a tinnitus survey questionnaire, and their tinnitus was evaluated using tinnitus matching procedures.Results: Findings revealed clinically relevant differences in attributes of tinnitus in patients with and without TMD. Most of the participants in group A matched their tinnitus to a 6 000 Hz tone or noise, at lower intensity levels than participants in group B, although these results were not statistically significant. Participants in group A associated their tinnitus with a single sound whereas some participants in group B associated it with more than one sound. More participants in group B reported the duration of their tinnitus as constant.Conclusions: Tinnitus may occur in patients with TMD, and be of high frequency. This highlights the importance of thorough assessment for patients with tinnitus as this might have implications for diagnosis and management.

    Full Text Available BACK GROUND: In India, there has been a considerable rethink on the curriculum of medical education, specially, on the teaching and assessment methodology. Subjective assessment is slowly giving way to objective structured assessment. The aim of undergoing clinical ex amination is to assess the students learning skill, knowledge, professionalism and attitude avoiding examiners variability and bias. OSCE has been advocated as it overcomes the flaws of conventional clinical examination. OBJECTIVE: To find out effective, E valuation tool where the assessment is Structured, Competency based, In - depth testing of skills is done, And higher levels of Millers Pyramid is tested. Method: A comparative study was conducted in Tagore Medical College and Hospital among the 9 th Semester students. Scores obtained under both the methods were compared using statistical methods. After undergoing both the examination, feedback was collected to assess the attitude of the students towards both the methods. RESULTS: By quantitative analysis, t he two - tailed P value is 0.000 which is considered to be extremely statistically significant. So, the null hypothesis was rejected. So, there is strong reason to believe that students are able to score better under a better examination methodology. By qualit ative analysis, attitude of the students towards OSCE method was better than CCE method. CONCLUSION: It is proved that Objective structured clinical examination a statistically significant better evaluation tool with comparison to conventional examination and it can be included in the undergraduate assessment method.

    Full Text Available Objective: This study was designed to compare the pattern of obstructive sleep apnea (OSA among obese and nonobese subjects regarding clinical and polysomnographic data obtained for a polysomnographic study. Methods: A cross-sectional retrospective descriptive study was conducted by analyzing polysomnographic data in 112 consecutive patients underwent a sleep study at our sleep laboratory from January 2009 to July 2010. Out of them, 81 were diagnosed to have OSA (apnea-hypopnoea Index ≥5. These patients were classified in two groups with body mass index (BMI 0.001. The minimal oxygen saturation was lower in the obese than the nonobese group (68.5 ± 13.00 vs. 80.3 ± 7.40, P0.001 and was well below 90% in both groups. Overall, the OSA in nonobese patients was mild-to-moderate as compared to that of the obese and no significant differences were observed between them as regard to age, gender, mean neck circumference, excessive daytime sleepiness, adenoid or tonsillar enlargement, smoking, and remaining polysomnographic parameters. Conclusion: Obstructive sleep apnea can occur in nonobese persons though with less severity as compared to obese leading to a concept that OSA is not restricted to obese persons only and there is a high demand of its awareness regarding evaluation, diagnosis, and management in such individuals.

    CT image reconstruction is typically evaluated based on the ability to reduce the radiation dose to as-low-as-reasonably-achievable (ALARA) while maintaining acceptable image quality. However, the determination of common image quality metrics, such as noise, contrast, and contrast-to-noise ratio, is often insufficient for describing clinical radiotherapy task performance. In this study we designed and implemented a new comparative analysis method associating image quality, radiation dose, and patient size with radiotherapy task performance, with the purpose of guiding the clinical radiotherapy usage of CT reconstruction algorithms. The iDose4 iterative reconstruction algorithm was selected as the target for comparison, wherein filtered back-projection (FBP) reconstruction was regarded as the baseline. Both phantom and patient images were analyzed. A layer-adjustable anthropomorphic pelvis phantom capable of mimicking 38-58 cm lateral diameter-sized patients was imaged and reconstructed by the FBP and iDose4 algorithms with varying noise-reduction-levels, respectively. The resulting image sets were quantitatively assessed by two image quality indices, noise and contrast-to-noise ratio, and two clinical task-based indices, target CT Hounsfield number (for electron density determination) and structure contouring accuracy (for dose-volume calculations). Additionally, CT images of 34 patients reconstructed with iDose4 with six noise reduction levels were qualitatively evaluated by two radiation oncologists using a five-point scoring mechanism. For the phantom experiments, iDose4 achieved noise reduction up to 66.1% and CNR improvement up to 53.2%, compared to FBP without considering the changes of spatial resolution among images and the clinical acceptance of reconstructed images. Such improvements consistently appeared across different iDose4 noise reduction levels, exhibiting limited interlevel noise (phantom size. The iDose4 algorithm with a moderate noise reduction

    This article reports a validation study of the Italian version of the Resilience Scale for Adults (RSA), a measure designed to assess individual, family, and social resilience protective resources. The RSA was administered to a clinical (i.e., substance use disorders, or SUD; N = 437) and a nonclinical sample (N = 337). A confirmatory factor analyses supported the original 6-factor structure of the RSA in both samples. The RSA correlated positively with functional coping strategies and negatively with perceived stress and dysfunctional coping strategies. Moreover, the RSA subscales discriminated between SUD and non-SUD individuals. Factorial invariance testing also confirmed comparable psychometric properties across gender. The results confirm good psychometric properties of the Italian RSA and provide support for the construct validity of the scale. The RSA may be suited for use in studies examining natural course and intervention trials. (PsycINFO Database Record PMID:27031088

    International Nuclear Information System (INIS)

    Objective: compare the dose delivered to patients and image quality in clinical routine to perform an abdominal CT scan with no iterative reconstruction techniques (IR) relative to an examination conducted on a scanner with IR. Materials and methods: this is a retrospective study of 30 patients who underwent two abdominal examinations: one on a 40-slice scanner (TDM40) without IR and another one on a 256-slice scanner with IR (TDM256). The patients, on medical follow-up for a chronic abdominal disease, had an exam on each scanner using the same protocol comprising an abdomino-pelvic time portal phase. The length of acquisition, the effective dose and the dose length product (DLP) as well as quantitative and qualitative assessments of the image were compared. Results: the average effective dose per examination was 17.3 mSv with the TDM40 (PDL: 1019 mGy.cm) against 11.1 mSv with the TDM256 (PDL: 654 mGy.cm), hence a reduction of 35.8% (p < 0.001). The length of acquisition and quantification were comparable in both groups. The qualitative assessment was slightly higher on the TDM40 but no examination was considered suboptimal. Conclusion: using a scanner equipped with IR significantly reduces the effective dose while maintaining image quality. (authors)

    Full Text Available Aim: The present study was aimed to study the use of cell counts as an early indicator of mammary health. Materials and Methods: Milk and blood cell counts were estimated from 8 healthy, 8 subclinical (SCM, and 8 clinically mastitis (CM groups of Karan Fries (KF cows. Results: Total leucocyte counts and neutrophil percent in blood and milk somatic cells and milk neutrophil percent of healthy cows increased significantly (p<0.05 in SCM cows and CM cows. Viability of blood and milk neutrophils was more in healthy cows, but decreased significantly (p<0.05 in SCM and CM cows. Significant (p<0.05 decrease were also observed in both the blood and milk lymphocytes and monocytes of SCM and CM cows. Phagocytic activity (PA of blood neutrophils also decreased significantly (p<0.05 in SCM cows. There was no difference between the PA of SCM and CM cows. Milk neutrophil percent was more in the SCM and clinically infected milk than in the blood of these cows. About 96-97% of the neutrophils had segmented nucleus in both healthy and subclinical milk, whereas, 2-3% were having band shaped or immature nuclei. There was a significant decrease in the segmented neutrophils, whereas, band neutrophils increase significantly to about 5% in the infected milk of mastitic cows. Viability of the milk neutrophils decreased more in case of subclinical and clinical milk as compared to that of blood. PA was found to be highest in the milk of healthy group of cows, but decreased significantly (p<0.05 in subclinically infected cows. However, there was no difference between the PA of milk neutrophils of SCM and CM cows. PA of milk was also found to be significantly lower in the milk of healthy cows when compared to that of blood neutrophils. Conclusion: This study indicated that percent neutrophils and their type in conjunction with milk somatic cell counts can be used as a more reliable indicator of mammary health in cows.

  13. Non-randomized clinical study comparing chemotherapy plus radiotherapy with radiotherapy alone in neoadjuvant therapy for oral cancer

    International Nuclear Information System (INIS)

    Neoadjuvant therapy plays an important role for organ preservation and survival rate in the treatment of oral cancer. We clinically compared the effect of neoadjuvant radiotherapy and chemoradiotherapy in patients with oral cancer. We retrospectively examined 47 patients diagnosed with oral squamous cell carcinoma who underwent neoadjuvant therapy followed by curative surgery in the oral and maxillofacial surgery department of Ehime University Hospital. We divided them into two groups: radiotherapy alone (24 cases) and chemoradiotherapy (23 cases). The patients in the radiotherapy group underwent irradiation of 32.6±5.0 Gy (mean ±SD). The patients in the chemoradiotherapy group received a low-dose fraction of cisplatin (8 mg/mm2/day, 5 days a week; total dose: 139.4±67.1 mg) and 5-fluorouracil (300 mg/mm2/day, 5 days a week; total dose: 5,900±1,839.8 mg) combined with simultaneous irradiation of 31.0±3.2 Gy. None of the 24 patients had a complete response to radiotherapy alone and 12 (50%) had a partial response. Six (26%) of the 23 patients had a complete response to chemoradiotherapy and 12 (52%) had a partial response. The primary control rate (82.6%) to chemoradiotherapy was higher than that (67.5%) to radiotherapy alone although no significant difference was found. The 5-year survival rate was 64.3% in the radiotherapy group and 62.8% in the chemoradiotherapy group. The findings of the present study suggest that while the combination of radiation and cisplatin/5-fluorouracil in neoadjuvant therapy for oral cancer may not bring a significant benefit to improve survival rate, the primary local control rate is improved in comparison with radiotherapy alone.

    To evaluate differences anatomical location and age groups on CT and clinical data in deep neck abscess. This study included 200 patients who underwent CT and were diagnosed with a deep neck abscess, from December 2005 to July 2010. Patients were divided into four groups by age (children, adolescent, adult, elderly). Next, the anatomic location, location multiplicity and clinical data regarding the deep neck abscesses were analyzed retrospectively. The deep neck abscesses observed were defined as superficial or deep and partitioned into sub-groups, with further analysis of their clinical data. The incidence of the parapharyngeal abscess was more frequent in children and elderly groups (p < 0.05). The masticator abscess was only observed among patients in the elderly group (p < 0.05). Multiple locations were observed with increased frequency in children and elderly groups (p < 0.05). Swelling in the neck was more frequently observed in children and elderly groups (p < 0.05), cervical lymphadenitis was frequently seen in children and adolescent groups (p < 0.05), and the incidence of symptoms including sore throat were significantly increased in adolescent and adult groups (p < 0.05). Location multiplicity was significantly higher in parapharyngeal, retropharyngeal, submandibular, danger, visceral and masticator spaces than other spaces (p < 0.05). With regards to anatomic location, neck swelling was more frequent in superficial group and sore throat was more frequent in deep group (p < 0.05). Deep neck abscess would show significant differences with regards to the abscess location, location multiplicity, and clinical symptoms according to age. The clinical symptoms observed are dependent on the anatomic location as defined by a superficial or deep abscess.

    The aim of this study was to identify factors predisposing to lung infarction in patients with pulmonary embolism (PE). We performed a retrospective analysis on 154 patients with the final diagnosis of PE being examined between January 2009 and December 2012 by means of a Toshiba Aquilion 64 CT scanner. The severity of clinical symptoms was defined by means of a clinical index with 4 classes. The pulmonary clot load was quantified using a modified severity index of PE as proposed by Miller. We correlated several potential predictors of pulmonary infarction such as demographic data, pulmonary clot burden, distance of total vascular obstruction and pleura, the presence of cardiac congestion, signs of chronic bronchitis or emphysema with the occurrence of pulmonary infarction. Computed tomography revealed 78 areas of pulmonary infarction in 45/154 (29.2%) patients. The presence of infarction was significantly higher in the right lung than in the left lung (p < 0.001). We found no correlation between pulmonary infarction and the presence of accompanying malignant diseases (r=-0.069), signs of chronic bronchitis (r=-0.109), cardiac congestion (r=-0.076), the quantified clot burden score (r=0.176), and the severity of symptoms (r=-0.024). Only a very weak negative correlation between the presence of infarction and age (r=-0.199) was seen. However, we could demonstrate a moderate negative correlation between the distance of total vascular occlusion and the occurrence of infarction (r=-0.504). Neither cardiac congestion nor the degree of pulmonary vascular obstruction are main factors predisposing to pulmonary infarction in patients with PE. It seems that a peripheral total vascular obstruction more often results in infarction than even massive central clot burden.

    2015-12-01

    Full Text Available INTRODUCTION Many pharmacological agents have been evaluated in regards to their efficacy of blunting the adverse cardiovascular response to laryngoscopy and tracheal intubation. The aim of this study was to evaluate the efficacy of dexmedetomidine compared to fentanyl in blunting the haemodynamic response to laryngoscopy and intubation. METHOD Sixty patients were randomly allocated into two groups (30 patients in each group. The group D received intravenously 1 µgm/kg dexmedetomidine infusion and group F received 2µgm/kg fentanyl infusion. The study drugs were prepared in an identical looking container and were infused fifteen minutes prior to induction of anaesthesia. The study drugs were infused over a period of ten minutes and all the patients underwent a similar anaesthetics technique. Heart rate (HR and blood pressure (systolic, diastolic and mean blood pressure were noted at baseline, at the end of infusion of the study drugs, after induction of anaesthesia, immediately after laryngoscopy and intubation and at 1, 3, 5, 7 and 10 minutes after laryngoscopy and intubation. RESULTS HR significantly decreased in the group D when compared to group F immediately after study drug infusion and there was statistically significant reduction in heart rate for up to 5 min after intubation in both the groups. Although HR increased after intubation in both the groups, the magnitude was lower in the group D. In both the groups, laryngoscopy and intubation led to an increase in systolic, diastolic and mean arterial pressure; the magnitude was lower in the group D. CONCLUSION Dexmeditomidine (1µ/kg attenuates these untoward responses of laryngoscopy and intubation more effectively than fentanyl (2 µ/kg when administered as bolus dose in the pre-induction period of general anaesthesia.

    This study addressed psychological needs, patterns of service utilization and provision of care in a specialist mental health service for young refugees and asylum seekers in London. Comparisons were made between two groups with different levels of postulated mental health need: unaccompanied minors (UAMs; n = 49) and children accompanied to the UK by one or more primary caregivers (n = 29). Significant differences were observed in referral pathways, with UAMs more likely to be referred by social services and less likely to be referred from medical agencies. UAMs also attended fewer sessions during treatment, and missed a greater proportion of scheduled appointments. Contrary to prediction, group comparisons revealed similar levels of post-migration stress and overall psychological morbidity. However, UAMs experienced significantly more traumatic events prior to resettlement, and were more likely to exhibit symptoms of post-traumatic stress disorder (PTSD) than their accompanied peers. Despite their elevated risk of PTSD, UAMs were less likely than accompanied children to have received trauma-focused interventions. UAMs were also significantly less likely to have been treated using cognitive therapy, anxiety management and parent/carer training, as well as receiving fewer types of practical assistance with basic social needs. The clinical and service implications of these findings are discussed. PMID:19293323

    Full Text Available Abstract Background The zygomatic maxillary complex (ZMC fractures are one of the most frequent injuries of the facial skeleton due to its position and facial contour. Assaults, road traffic accidents and falls are the principal etiologic factors that may cause fractures of zygomatic bone. The different fixation methods are applied to treat the zygomatic bone fractures, with many more classifications which have been described in the literature for the ease of management. The type of the fracture, its severity and associated facial fractures usually interferes the treatment modality. Purpose of study The aim of this paper is to show the results of 18yrs prospective blind comparative study using wire and plate osteosynthesis which needed open reduction and internal fixation involving Type II to Type IV Spissel and Schroll ZMC fractures. Materials and methods Total 80 cases included in the study out of 1780 ZMC cases which were treated using wire and plate osteosynthesis over a period of 18 yrs, involving only Type II to Type IV Spissel and Schroll ZMC fractures. Other types excluded from study to prevent observer bias. All the fixations carried out through Standard Dingman's incision using stainless steel 26 gauze wire and titanium 1.5 mm mini plate system under general anesthesia by single maxillofacial surgeon and evaluated by another maxillofacial surgeon who is blinded for surgical procedure after 2 and 4 wks of follow-up for facial symmetry, wound healing, functional assessment (mouth opening, diplopia, and sensory disturbance. All the data tabulated in Excel software (Microsoft for statistical analysis. P-value calculated to know the Significance of treatment modality in all aspects. Results Result shows no significant p-values indicating both the operating techniques are equally efficient in the surgical management of ZMC fracture. Conclusion Osteosynthesis by mini plates is simple, logical and effective treatment compared to wire

    Full Text Available Context: Gingival changes in pregnancy have been attributed to changes in the subgingival biofilm related to hormonal variations. Aims: To evaluate the subgingival plaque microflora in pregnant and nonpregnant women to determine if pregnancy induces any alterations in the subgingival plaque and to associate these changes with changes in periodontal status. Settings and Design: Thirty pregnant and 10 nonpregnant women within the age group of 20-35 years having a probing pocket depth (PPD of 3-4 mm were included in the study. The pregnant women were equally divided into 3 groups of 10, each belonging to I, II, and III trimester. Materials and Methods: Plaque index, gingival index, PPD, and microbiologic evaluation for specific bacterial counts for Prevotella intermedia, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Parvimonas micra, and Fusobacterium nucleatum were carried out for all subjects. Statistical Analysis: Mann-Whitney U test. Results: Increase in gingival inflammation was observed in II and III trimester as compared with I trimester and control. Plaque scores did not show any significant difference between pregnant and nonpregnant women. Specific bacterial examination revealed an increase in proportion of P. intermedia in pregnant women of both II and III trimester as compared with I trimester and nonpregnant women. Conclusions: A definite increase in proportions of P. intermedia occurs in subgingival plaque microflora in pregnancy that may be responsible for the exaggerated gingival response.

  14. Subjective vs. objective evaluation of gallbladder opacification during oral cholecystography in comparative clinical trials: implications for studies involving visual assessment

    International Nuclear Information System (INIS)

    Radiographs and CT images taken during oral cholecystography in dogs were interpreted in an independent, blind fashion by three radiologists on two occasions and visual assessment of gallbladder density compared to the actual CT values. While there was significant intra- and inter-observer variation, the mean scores for the observers' interpretations of both radiographs and prints correlated well with the actual CT values (p > 0.05). In five out of six comparisons between first and second readings, the observers gave a lower score on the second reading. The considerable variation reflects the problems inherent in subjective evaluation of agents that produce small but measurable differences in radiographic density. Studies involving such subjective data have to be carefully designed in order to obtain meaningful results

    The purpose of this open, controlled, and randomized study was to evaluate the effectiveness of aceclofenac compared with paracetamol in improving the signs and symptoms of viral pharyngoamygdalitis and to evaluate the safety of both drugs. Thirty outpatients (age range 18-65 years) with acute viral pharyngoamygdalitis received either aceclofenac 100 mg/12 h or paracetamol 650 mg/ 12 h per os. Patients were evaluated at baseline and on days 1, 3, and 7 after beginning treatment. The parameters of effectiveness evaluated were: severity of pharyngoamygdalitis, spontaneous pharyngeal pain, saliva swallowing, and duration of pharyngeal pain. The results showed that the aceclofenac group had a significant decrease in the severity of pharyngoamygdalitis and spontaneous pharyngeal pain after day 1 of treatment (p paracetamol group showed no improvement in these parameters until day 3 of treatment (p paracetamol.

  17. A comparative study of clinical signs, computed tomography, and electroencephalography after direct operation of ruptured anterior communicating aneurysms, 1

    International Nuclear Information System (INIS)

    Eight cases with ruptured anterior communicating aneurysms, who developed mental signs of mild degree lasting more than two weeks following direct operation, were subjected to our study. The following results were obtained. 1) The mental signs of mild degree in 8 cases consisted of memory and emotional disturbances. The main findings of CT scan was low density area in the subcortical and cortical areas of the frontal lobe. There was no close correlation on CT findings between memory and emotional disturbances. 2) Abnormal density areas were detected on CT scan, but EEG showed no localized abnormalities of slow waves. Abnormal density areas were not clearly shown on CT, but EEG showed localized abnormalities. Background activities on EEG were favorable despite lesions detected on CT. Either local or diffuse abnormalities were observed in EEG background activities while no abnormal mental signs were recognized. 3) In cases with no apparent abnormal findings on CT and with favorable background activities on EEG, EEG showed marked build up during hyperventilation. 4) As indicated by the above data, comparative studies of CT and EEG findings revealed differences in sites of abnormalities and degree of abnormalities. This is considered caused by a possible increase in cerebral blood flow and metabolism at initiation of chronic stage following subarachnoid hemorrhage-resulting in the disappearance of abnormalities on EEG.

  18. A prospective, comparative study of ventilation-perfusion scintigraphy and clinical evaluation versus digital subtraction angiography in acute pulmonary thromboembolism

    International Nuclear Information System (INIS)

    Patients with symptoms of acute pulmonary thromboembolism (APE) of short duration were investigated with digital subtraction angiography (DSA) and ventilation/perfusion lung scintigraphy (V/Q scan), and a standardised clinical evaluation was performed. Forty-six angiograms (96%) were diagnostic at the segmental level and were used as reference. In all V/Q scans classified as normal or of high probability for APE, a complete agreement with DSA was found. In scan categories with low or intermediate probability, where the incidence of APE was 32%, there was considerable inter-observer disagreement. Clinical assessment alone was of limited value, but in patients with low clinical suspicion no APE was found. The results indicate that normal and high probability V/Q scans are very reliable for excluding and identifying APE, respectively, but also that fairly large APE cannot be diagnosed with lung scanning. Subdivision of V/Q scans into more than three categories (normal, high probability and inconclusive) seems to be of no practical value. Using a pulsed sequence technique, high frame rate and central injection, DSA is a valuable clinical tool for diagnosing APE down to the segmental level. (orig.)

    Full Text Available INTRODUCTION Laryngoscopy and intubation is an integral part for providing general anaesthesia to patients undergoing various types of surgery. It also plays an important role in critical care units viz. for providing mechanical ventilation. It is a very essential tool in the hands of anaesthesiologist in maintaining airway. The present study is undertaken to determine and compare the efficacy of single bolus dose of IV esmolol 1 mg/kg and IV fentanyl 2 mcg/kg in attenuating the haemodynamic responses to laryngoscopy and tracheal intubation and to ascertain the effectiveness of esmolol hydrochloride and fentanyl citrate in suppressing sympathetic responses. MATERIAL & METHODS The study was conducted under the Department of Anaesthesiology and Critical Care, Assam Medical College and Hospital, Dibrugarh, during the period July 2013 to June 2014. For this purpose, 150 patients of either sex between 20-50 years of ASA I & II physical status were selected after obtaining informed and written consent and were divided into two groups namely, Group E receiving IV esmolol (1 mg/kg and Group F receiving IV fentanyl (2 mcg/kg. RESULTS Inj. fentanyl 2 mcg/kg IV administered 5 minutes before laryngoscopy and intubation was able to prevent adverse haemodynamic changes better than Inj. esmolol 1 mg/kg IV administered 3 minutes prior to laryngoscopy and intubation during elective surgeries under general anaesthesia. CONCLUSION Hence, from the findings of this study we can conclude that IV bolus dose of fentanyl 2 mcg/kg administered 5 minutes before laryngoscopy and intubation can attenuate the sympathetic response to laryngoscopy and intubation without any side effects of the drug in healthy patients undergoing elective surgeries under general anaesthesia.

    Aim: To study the effect of intracavemous sodium nitropmsside (SNP), a nitric oxide (NO) donor, on penile erection. Methods: Forty-two patients with erectile dysfunction (ED) were randomly assigned to receive SNP 300μg or the control drugs (papaverine 30mg+phentolamine 1mg) intracavemously crosswise one week apart. The penile length, circumference and hardness after the administration of the experimental and control drugs were assessed and compared statistically. Results: (1)There was no significant difference between the changes in penile length and circumference in the two occasions; (2)In 25 SNP and 28 control cases, the hardness of the penis was scored above 100 as evaluated by the Virag method (P>0.05);(3)The duration of erection in the controls was longer than that in the SNP, but there were three priapism in the controls and not a single one in the SNP; (4)there was no apparent change in the heart rate and blood pressure in both occasions; other side effects were minimal except slight local pain in a few controls. Conclusion: SNP facilitates relaxation of the penile smooth muscle and penile erection without significant side effects. SNP may be used in ED patients that experience pain and priapism with papaverine/phentolamine.(Asian J Androl 2000 Dec;2:301-303)

    2009-04-01

    Full Text Available Detection of slime in Pseudomonas aeruginosa can be useful in understanding the virulence of this organism. Here, comparative studies of two phenotypic methods using the tube method and the spectrophotometric method for slime production from 100 clinically and 21 environmentally significant isolates of P. aeruginosa were performed. A total of 68 isolates were positive by either of the tests whereas only 34 were positive by both the tests. The tube method detected slime significantly in more number of isolates than the spectrophotometric method. The tube test was found to be superior to the spectrophotometric method in ease of performance, interpretation and sensitivity. Among the clinical isolates, systemic isolates produce less slime compared to wound, respiratory and urinary isolates. Isolates from the hospital environment produced more slime indicating that this virulence marker helps the organism to survive for longer periods and cause nosocomial infections.

    Full Text Available OBJECTIVE: To compare assessed EFW by clinical method (Johnson’s formula and ultrasonography with birth weight for accuracy. AIM: to prove reliability and accuracy of the clinical and sonographic method to assess the EFW. INTRODUCTION: Fetal weight is an important predictor of perinatal morbidity, mortality and maternal mortality. Accurate estimation of fetal weight is paramount importance in high risk pregnancies for the management of labor. An infant born with unsuspected growth restriction is more likely to have significant compromise. The two main methods for predicting birth weight are clinical method and ultrasonography. These methods require clinical skills and expertise to get the result with more accuracy. MATERIALS AND METHOD: 50 term pregnant women were selected by conventional sampling method. All term women were admitted after obtaining written and informed consent and subjected for clinical examination and ultrasonography. Those delivered within 24 hrs. following assessment were included in the study. Two senior residents were assigned to do clinical examination by Johnson’s formula. The equation for Johnson’s technique is as follows: fetal weight (g = [fundal height (cm-n]*155(n=12 if vertex is above the level of Ischial spine or 11 if below ischial spine. Ultrasound estimation was performed by senior obstetrician trained in ultrasonography and recorded using GE200L. Hadlock formula-2 was set for estimation. Women were observed until birth. All new born were weighed using same scale after birth. The estimated weight by both methods was compared with birth weight. Accuracy determined by percentage error and proportion of estimate within +/_10% of actual birth weight. RESULT: For statistical analysis birth weight was categorized in to VLBW, LBW, NBW and HBW. In LBW group the mean ABW 2359g (151 SD, while mean EFW by USG and Johnson`s formula reported were2492g (246 SD and3109g (369 SD respectively. In NBW group mean ABW 3074g

    2008-12-01

    Full Text Available Instead of haemostatic effect, feracrylum provides antibacterial activity; wound improvement has been clinically proven. Feracrylum is a water soluble mixture of incomplete ferrous salt of polyacrylic acid containing 0.05 to 0.5% of iron in physiologic solution (0.85% solution of sodium chloride. A clinical study on safety and efficacy of feracrylum compared to silver sulfadiazine (SSD was conducted in burn management, since with the widely use of SSD, the sulfadiazine’s disadvantages lead to wound healing impairment. In this open, randomized, controlled study, feracrylum and SSD were topically applied, each on different side of the burnt areas in parts of body for a treatment period of eleven days. Of eight enrolled patients, seven patients completed the study; one patient withdrew due to acute burn complication. On day 7th and 11th, the re-epithelialization in group receiving feracrylum increased as the raw surface area reduced. Mean percentages of epithelialization on both evaluation days in Feracrylum group were 70.53±24.298 and 81.71±28.922, respectively, which were higher than SSD group (66.15±25.080 and 64.64±74.684 respectively. Feracrylum was found to be safe and well tolerated. This study showed a clinical difference although it was not significant statistically.

  10. The Urine Proteome Profile Is Different in Neuromyelitis Optica Compared to Multiple Sclerosis: A Clinical Proteome Study.

    Directory of Open Access Journals (Sweden)

    Helle H Nielsen

    Full Text Available Inflammatory demyelinating diseases of the CNS comprise a broad spectrum of diseases like neuromyelitis optica (NMO, NMO spectrum disorders (NMO-SD and multiple sclerosis (MS. Despite clear classification criteria, differentiation can be difficult. We hypothesized that the urine proteome may differentiate NMO from MS.The proteins in urine samples from anti-aquaporin 4 (AQP4 seropositive NMO/NMO-SD patients (n = 32, patients with MS (n = 46 and healthy subjects (HS, n = 31 were examined by quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS after trypsin digestion and iTRAQ labelling. Immunoglobulins (Ig in the urine were validated by nephelometry in an independent cohort (n = 9-10 pr. groups.The analysis identified a total of 1112 different proteins of which 333 were shared by all 109 subjects. Cluster analysis revealed differences in the urine proteome of NMO/NMO-SD compared to HS and MS. Principal component analysis also suggested that the NMO/NMO-SD proteome profile was useful for classification. Multivariate regression analysis revealed a 3-protein profile for the NMO/NMO-SD versus HS discrimination, a 6-protein profile for NMO/NMO-SD versus MS discrimination and an 11-protein profile for MS versus HS discrimination. All protein panels yielded highly significant ROC curves (AUC in all cases >0.85, p≤0.0002. Nephelometry confirmed the presence of increased Ig-light chains in the urine of patients with NMO/NMO-SD.The urine proteome profile of patients with NMO/NMO-SD is different from MS and HS. This may reflect differences in the pathogenesis of NMO/NMO-SD versus MS and suggests that urine may be a potential source of biomarkers differentiating NMO/NMO-SD from MS.

    2015-01-01

    Full Text Available Background: The presence of an adequate width of keratinized tissue is important to maintain a healthy dentogingival junction. In case of inadequate width of attached gingiva, the gingival augmentation procedure has been performed classically using the patient's own masticatory mucosa and more recently, using an acellular dermal allograft as the donor material. Aims: The aim of the clinical study was to evaluate and compare the effectiveness of free gingival graft (FGG and acellular dermal matrix (ADM allograft in the ability to increase the zone of attached gingiva. Materials and Methods: Fifteen patients with 30 sites showing the inadequate width of attached gingiva (≤1 mm were enrolled for the split-mouth study. The width of keratinized gingiva and other clinical parameters were recorded at baseline and 12th month postoperatively. Statistical Analysis: The difference in clinical parameters within the group was assessed by Wilcoxon signed rank test. However, Mann–Whitney U-test was used to analyze the differences between test and control groups. Results: The width of attached gingiva increased significantly (P < 0.01 following both the treatments but comparatively lesser gain with ADM allograft (2.13 mm vs. 4.8 mm. ADM site had significantly more shrinkage (76.6% than FGG site (49.7%. Though FGG was found to be more effective, clinicians can prefer ADM allograft because of its certain advantages over the FGG. Conclusion: ADM allograft has resulted in sufficient increase in width of attached gingiva although lesser than FGG. Considering the disadvantages of FGG, it can be concluded that ADM allograft can be used as an alternative to FGG in increasing width of attached gingival in certain clinical situations.

    Full Text Available Background: Resistance to cephalosporins due to β-lactamases is a major concern worldwide. However recent trend is to use β-lactamase inhibitor combinations. Potential combination is cefiximeclavulanate. Objective: Present study aims at the comparative evaluation of Fixed-Dose Combination (FDC of cefixime‑clavulanate and cefixime-alone in Klebsiella pneumoniae clinical isolates. Material and Methods: Study included 200 clinical isolates of K. pneumoniae. The Comparative Antimicrobial Susceptibility Test (AST of cefixime‑clavulanate (5µg/10µg combination and cefixime-alone(5µg was done by measurement and comparison of zone of lysis produced by both. All values were expressed in mean ± SD. Paired‘t’ test was used to determine statistical difference between different groups under study. P values < 0.05 were considered statistically significant. Isolates were tested for ExtendedSpectrum β-lactamase (ESBL, AmpC β-lactamase (AmpC and metallo β-lactamase (MBL production by Clinical Laboratory Standards Institute - Phenotypic Disk Confirmatory Test (CLSI-PDCT, AmpC β-lactamase sterile disk test and Imipenem-Ethylene Di-amine Tetracetic Acid – Double disk synergy test (Imipenem-EDTA DDST respectively. Results: Comparative AST resulted in statistically significant (P < 0.001 increased zones in cefixime‑clavulanate combination than cefixime-alone in all isolates studied. When zones were evaluated separately only in three β-lactamase producing isolates; cefiximeclavulanate combination showed much higher zones in ESBL-producers (n=30 (P < 0.001, but not in AmpC-producers (n=32 (P = 0.5559 and MBLproducers (n=06 (P = 0.7815. Conclusion: Present study demonstrates the best bactericidal killing effect of cefixime-clavulanate compared to cefixime-alone. It is also of therapeutic significance in the treatment of infections caused by K. pneumoniae producing ESBLs. We recommend comparative AST method when commercially available newer

  13. Double-blind, randomized clinical study comparing hyaluronic acid cream to placebo in patients treated with radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The effect of hyaluronic acid (Ialugen[reg] cream) on acute skin reactions after radiotherapy, was assessed in a randomized, double-blind, placebo-controlled study. Material and methods: Out of the 152 patients presenting with head and neck, breast or pelvic carcinomas and registered in the study, 134 cases - 70 in the Ialugen group (IA) and 64 in the placebo group (PBO) - completed their IA or PBO treatment. At the time of randomisation, these two groups were balanced for sex, age, weight and height. The mean total dose of radiation given during the study was 60.6±10.9 Gy in the IA group and 64.3±10.8 Gy in the PBO group (P =0.47). Results: Acute radio-epithelitis scores were significantly higher in the PBO group than in the IA group, starting from the control at week 3 and throughout the 6 weeks of treatment (P<0.01 from week 3 to week 7; P<0.05 at weeks 8 and 10). Likewise, the global efficacy judgement expressed, at the end of treatment, by both the physician and the patient showed a significant difference in favour of Ialugen (P<0.01 and P<0.05, respectively). There was no significant difference of tolerance between the IA and PBO treatments (P=0.18 according to the physician and P=0.42 from the patient's viewpoint). Conclusion: The prophylactic use of a cream with hyaluronic acid is shown to reduce the incidence of high grade radio-epithelitis, suggesting an interesting role of the hyaluronic acid cream as supportive treatment to improve compliance and quality of life in patients undergoing radiation therapy

    Full Text Available Chittodvega is a Manasa Vikara described by Charak. It has been considered as a perfect word for highlighting the status of anxiety, which is produced due to vitiation of Raja and Tama. In addition Prana, Udana, Vyana Vayu; Sadhaka Pitta; and Tarpaka Kapha are also provocated factors in it. On the basis of these considerations it can be postulated that Chittodvega is a minor mental disorder. In modern parlances also, the neurotic disorders which include anxiety disorders are considered as minor mental disorder in comparison to major mental condition like schizophrenia etc. Beneficial action of Shirodhara in the management of anxiety disorder has been reported. Acharya Charaka has advised to use Medhya Rasayana drugs for the mental disorders, especially for the promotion of Medha. Sankhapuspi (Convolvulus pluricaulis has been considered best amongst the Medhya Rasayana drugs. Here in this study the total 36 patients of Chittodvega (Anxiety disorders were randomly divided into two groups: 1 Group-J: The patients of this group were subjected to Jaladhara for 30 minutes daily in the morning between 8:30 to 11:00 AM for 6 weeks with a gap of 1 week after completion of three weeks course of Jaladhara. 2 Group-SR: The Patients of this group were administered 3 gms powders of Sankhapuspi Rasayana three times a day orally with water for 6 weeks.

    A low dose of midazolam-medetomidine-ketamine (MMK) combination was evaluated in three increasing dosages. Each of the 18 cats was randomly allocated for several times to one of four groups. Five minutes after premedication with intramuscular (IM) 0.04 mg/kg atropine, group A (n = 43), B (n = 40) and C (n = 28) all were anaesthetized with 0.5 mg/kg midazolam, combined with 10, 20 or 30 microg/kg medetomidine, and 1.0, 2.0 or 3.0 mg/kg ketamine, respectively, IM in one syringe. Group D (n = 11) received the established combination of 50 microg/kg medetomidine and 10.0 mg/kg ketamine for comparison. Because this study was in cooperation with a project on dental prophylaxis, cats had to be immobilized for approximately 1 h. Therefore, anaesthesia was prolonged with propofol to effect, if necessary. Duration of MMK anaesthesia was between 30 +/- 15, 45 +/- 19 and 68 +/- 28 min in groups A, B and C respectively. A significant decrease of respiratory rate was observed with increasing dosage, but venous carbon dioxide (pCO(2)) and pH values in combination with arterial oxygen saturation (SpO(2)) values were not alarming. The diastolic blood pressure particularly showed an increase. MMK combination A showed the best cardiovascular results, but it cannot be recommended due to disadvantages like a long induction time sometimes accompanied by excitations and the short duration of surgical immobilization. Dosage C in contrast had fewer side effects but less favourable cardiovascular results and a longer recovery period. However, either dosage B or C was suitable as a repeatable IM immobilization method for non-invasive procedures in healthy cats. PMID:17877583

    Full Text Available Aims: The purpose of this study was to compare the clinical efficacy of subepithelial connective tissue graft and acellular dermal matrix graft associated with coronally repositioned flap in the treatment of Miller′s class I and II gingival recession, 6 months postoperatively. Settings and Design: Ten patients with bilateral Miller′s class I or class II gingival recession were randomly divided into two groups using a split-mouth study design. Materials and Methods: Group I (10 sites was treated with subepithelial connective tissue graft along with coronally repositioned flap and Group II (10 sites treated with acellular dermal matrix graft along with coronally repositioned flap. Clinical parameters like recession height and width, probing pocket depth, clinical attachment level, and width of keratinized gingiva were evaluated at baseline, 90 th day, and 180 th day for both groups. The percentage of root coverage was calculated based on the comparison of the recession height from 0 to 180 th day in both Groups I and II. Statistical Analysis Used: Intragroup parameters at different time points were measured using the Wilcoxon signed rank test and Mann-Whitney U test was employed to analyze the differences between test and control groups. Results: There was no statistically significant difference in recession height and width, gain in CAL, and increase in the width of keratinized gingiva between the two groups on the 180 th day. Both procedures showed clinically and statistically significant root coverage (Group I 96%, Group II 89.1% on the 180 th day. Conclusions: The results indicate that coverage of denuded root with both subepithelial connective tissue autograft and acellular dermal matrix allograft are very predictable procedures, which were stable for 6 months postoperatively.

    Thow, Megan; Ferguson, Stuart G

    2016-01-01

    Background Recruiting participants for research studies can be difficult and costly. The popularity of social media platforms (eg, Facebook) has seen corresponding growth in the number of researchers turning to social networking sites and their embedded advertising frameworks to locate eligible participants for studies. Compared with traditional recruitment strategies such as print media, social media advertising has been shown to be favorable in terms of its reach (especially with hard-to-reach populations), cost effectiveness, and usability. However, to date, no studies have examined how participants recruited via social media progress through a study compared with those recruited using more traditional recruitment strategies. Objectives (1) Examine whether visiting the study website prior to being contacted by researchers creates self-screened participants who are more likely to progress through all study phases (eligible, enrolled, completed); (2) compare conversion percentages and cost effectiveness of each recruitment method at each study phase; and, (3) compare demographic and smoking characteristics of participants recruited through each strategy to determine if they attract similar samples. Methods Participants recruited to a smoking cessation clinical trial were grouped by how they had become aware of the study: via social media (Facebook) or traditional media (eg, newspaper, flyers, radio, word of mouth). Groups were compared based on throughput data (conversion percentages and cost) as well as demographic and smoking characteristics. Results Visiting the study website did not result in individuals who were more likely to be eligible for (P=.24), enroll in (P=.20), or complete (P=.25) the study. While using social media was more cost effective than traditional methods when we examined earlier endpoints of the recruitment process (cost to obtain a screened respondent: AUD $22.73 vs $29.35; cost to obtain an eligible respondent: $37.56 vs $44.77), it was

    We report the results of applying comparative genomic hybridization (CGH) in a cytogenetic service laboratory for (1) determination of the origin of extra and missing chromosomal material in intricate cases of unbalanced aberrations and (2) detection of common prenatal numerical chromosome aberrations. A total of 11 fetal samples were analyzed. Seven cases of complex unbalanced aberrations that could not be identified reliably by conventional cytogenetics were successfully resolved by CGH analysis. CGH results were validated by using FISH with chromosome-specific probes. Four cases representing common prenatal numerical aberrations (trisomy 21, 18, and 13 and monosomy X) were also successfully diagnosed by CGH. We conclude that CGH is a powerful adjunct to traditional cytogenetic techniques that makes it possible to solve clinical cases of intricate unbalanced aberrations in a single hybridization. CGH may also be a useful adjunct to screen for euchromatic involvement in marker chromosomes. Further technical development may render CGH applicable for routine aberration screening. 16 refs., 4 figs., 2 tabs.

    In this present days and age, there are increasing needs for companies to monitor application and infrastructure health. Apart from having proactive measures to secure their application and infrastructure, many see monitoring dashboards as crucial investment in disaster preparedness. As companies struggle to find the best solution to cater for their needs and interest for monitoring their application and infrastructure's health, this paper summarizes the studies made on several known off-the-shelf operations dashboard and in-house developed dashboard. A few criteria of good dashboard are collected from previous studies carried out by several researchers and rank them according to importance and business needs. The finalized criteria that will be discussed in later sections are data visualization, performance indicator, dashboard personalization, audit capability and alert/ notification. Comparative studies between several popular dashboards were then carried out to determine whether they met these criteria that we derived from the first exercise. The findings hopefully can be used to educate and provide an overview of selecting the best IT application and infrastructure operations dashboard that suit business needs, thus become the main contribution of this paper.

    Background: Fetal malnutrition (FM) which describes the underweight/wasting seen in newborns is a significant contributor to perinatal morbidity and mortality and requires proper documentation. The objective of this study was to assess the nutritional status of term newborns at birth using Clinical Assessment of Nutritional (CAN) status score and four other anthropometric indices and to compare the efficiency of CAN score and the anthropometric indices in identifying FM in term newborns. Materials and Methods: The study was conducted on live singleton babies delivered ≥37–42 completed weeks of gestation at the inborn unit of Lagos University Teaching Hospital without major congenital abnormalities or severe perinatal illness. Birth weights and lengths were recorded at birth. Ponderal index (PI), body mass index (BMI), and mid-arm/head circumference (MAC/HC) ratio were calculated and the values were compared with standard curves. The CAN score consisted of inspection and estimation of loss of subcutaneous tissues and muscles. FM was defined as CAN score <25. Data were analyzed using the Statistical Package for Social Sciences statistics software version 17.0. Results: Two hundred and eighty-two newborns were analyzed. FM was identified in 14.5%, 10.3%, 13.1%, and 2.8% of newborns using CAN score, PI, BMI, and MAC/HC ratio, respectively. Out of the FM babies identified by CAN score, PI, MAC/HC, and BMI identified 19.5%, 12.3%, and 53.7% of them as FM also. BMI was the most sensitive anthropometric index for detecting FM. Conclusion: CAN score is a simple clinical tool for identifying FM and when used in conjunction with BMI will enhance FM detection. PMID:27226688

In the second study the major fetal and maternal indications were: anencephaly and cardiovascular problems. The 2nd study shows that in 202 cases (35.19%, abortion permission was issued after confirmation of three specialists (cases which were forecasted in the Predetermined Abortion Indications List. Conclusion: This study shows that in spite of all efforts made so far to present legal approaches for abortion, it is not still time to stop working on the issue and perhaps some other diseases should be added to the mentioned list in future; but this would definitely needs joint cooperation of different authorities, governmental and judicial organization.

  15. Comparative waste forms study

    International Nuclear Information System (INIS)

    A number of alternative process and waste form options exist for the immobilization of nuclear wastes. Although data exists on the characterization of these alternative waste forms, a straightforward comparison of product properties is difficult, due to the lack of standardized testing procedures. The characterization study described in this report involved the application of the same volatility, mechanical strength and leach tests to ten alternative waste forms, to assess product durability. Bulk property, phase analysis and microstructural examination of the simulated products, whose waste loading varied from 5% to 100% was also conducted. The specific waste forms investigated were as follows: Cold Pressed and Sintered PW-9 Calcine; Hot Pressed PW-9 Calcine; Hot Isostatic Pressed PW-9 Calcine; Cold Pressed and Sintered SPC-5B Supercalcine; Hot Isostatic pressed SPC-5B Supercalcine; Sintered PW-9 and 50% Glass Frit; Glass 76-68; Celsian Glass Ceramic; Type II Portland Cement and 10% PW-9 Calcine; and Type II Portland Cement and 10% SPC-5B Supercalcine. Bulk property data were used to calculate and compare the relative quantities of waste form volume produced at a spent fuel processing rate of 5 metric ton uranium/day. This quantity ranged from 3173 L/day (5280 Kg/day) for 10% SPC-5B supercalcine in cement to 83 L/day (294 Kg/day) for 100% calcine. Mechanical strength, volatility, and leach resistance tests provide data related to waste form durability. Glass, glass-ceramic and supercalcine ranked high in waste form durability where as the 100% PW-9 calcine ranked low. All other materials ranked between these two groupings

    The internal environment within animals or humans provides different conditions to invading saprophytic fungal pathogens, requiring the differential regulation of genes in comparison to environmental conditions. Understanding the mechanisms by which pathogens regulate genes within the host may be key in determining pathogen behavior within the host and may additionally facilitate further investigation into novel therapeutic agents. The heat shock protein (HSP)70 gene and its associated proteins have been frequently reported to be among the most highly expressed and dominant proteins present within various locations at physiological temperatures. The present study examined relative gene expression levels of the HSP70 gene in Aspergillus fumigatus isolates from both clinical and environmental origins, at a range of temperature points (20, 30, 37 and 42˚C) over five days, using reverse transcription‑quantitative polymerase chain reaction, comparing with a standard A. fumigatus strain incubated at 25˚C. The results indicated a differential gene expression pattern for the environmental and clinical isolates. During the five days, the HSP70 expression levels in the clinical samples were higher than in the environmental samples. However, the difference in the expression levels between the two groups at 42˚C was reduced. The mean HSP70 expression level over the five incubation days demonstrated a gradual and continual increasing trend by temperature elevation in both groups at 30, 37 and 42˚C, however, at 20˚C both groups demonstrated reduced expression. The temperature shift from 20 to 42˚C resulted in HSP70 induction and up to a 10‑ and 8.6‑fold change in HSP70 expression levels on the fifth day of incubation in the clinical and environmental groups, respectively. In conclusion, incubation at 37 and 42˚C resulted in the highest expression levels in both experimental groups, with these temperature points important for the induction of HSP70

    Background: To evaluate and compare the efficacy of mineral trioxide aggregate (MTA) and traditionally used calcium hydroxide (Ca(OH)2) in inducing root end formation of immature roots of traumatized young permanent anterior teeth. Materials and Methods: The study was carried out on 22 nonvital, immature permanent maxillary incisors. Samples were allotted into two groups - Group I MTA and Group II Ca(OH)2 Success rate was determined based upon the time duration required for apical barrier formation. The canals were obturated using gutta-percha points in MTA group, after 24 h, whereas in Ca(OH)2 group, obturation was carried out after radiographic confirmation of the apical barrier. The clinical and radiographic evaluation was carried out at a follow-up periods of 3, 6, and 9 months and statistical analysis was carried out by SPSS version 15.0 statistical analysis software (Chi-square test and fisher exact test). Results: In MTA Group, barrier formation was observed in 90.90% of the patients after 9 months whereas in Ca(OH)2 Group, the same was observed in 81.81%. The mean time required for barrier formation in MTA group was 4.90 months and 5.33 months in Ca(OH)2 group. Conclusion: MTA and Ca(OH)2, as medicaments for apexification, were comparable in terms of the evaluation parameters. However, MTA was beneficial in terms of immediate obturation of immature roots with wide open apices. PMID:27274351

    AIM: To compare the efficacy and safety of five days apostrophe therapy of mebendazole (MBZ) versus quinacrine (QC) on human giardiasis in children.METHODS: A clinical trial was carried out in paediatric patients (aged 5-15 years) with confirmed symptomatic G. duodenalis mono-infection. Patients were randomly assigned to receive either MBZ [200 mg taken three times per day (TID) (n = 61)] or QC [2 mg/kg bodyweight tid (n= 61)], both for five days. Follow-up faecal samples were obtained at 3, 5 and 7 d after the end of the treatment.RESULTS: Although the frequency of cure was higher for QC (83.6%) than for MBZ (78.7%), the difference was not statistically significant (P > 0.05). Adverse events were reported more in the QC group (P < 0.05),all of them transient and self-limiting.CONCLUSION: Despite final cure rates ocurring lower than expected, the overall results of this study reconfirmed the efficacy of MBZ in giardiasis and also indicate that, although comparable to QC, at least in this setting the 5 d course of MBZ did not appear to improve the cure rates in this intestinal parasitic infection.

    Full Text Available Objective: To compare the efficacy of agomelatine with escitalopram in the treatment of major depressive disorder (MDD, improve sleep in MDD patients and study the adverse effects of agomelatine. Materials and Methods: Randomized, parallel-group, open-label study. The primary efficacy outcome was change from baseline to last post-baseline value in Hamilton depression rating scale and Leeds sleep evaluation questionnaire scale. Both parametric and nonparametric tests were applied for analysis. Results: Within-group and between-groups comparison of the mean HAMD17 scores showed statistically significant changes (P < 0.0001. Escitalopram showed early onset of response and remission compared to agomelatine at 10th week (P < 0.0001 and 14th week (P < 0.0001, respectively. In agomelatine, within-group and between-groups change of the mean LSEQ score was statistically significant at subsequent follow-up visits (P < 0.0001. Conclusion: Escitalopram is superior to agomelatine in efficacy, considering the early response, early remission, and better relief from symptoms of MDD in adults. Agomelatine may be preferred in MDD patients having insomnia as a predominant symptom. Liver function monitoring should be done in patients on long-term agomelatine therapy.

    The aim of the present work was to study the epidemiology of Salmonella enterica serovar Enteritidis (S. Enteritidis) in Greece, comparing all the food and food animal isolates during a 3-year period with clinical isolates. Submission of the generated data to the PulseNet Europe database was carried out in order to study the population structure of this particular serovar and indicate possible connections with European strains. One hundred and sixty-eight (168) S. Enteritidis strains of human, animal, and food origin, isolated during the period 2008-2010 in Greece, were studied. Strains were characterized by phenotypic (antibiotic resistance) and molecular [pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST)] methods. PFGE revealed 39 XbaI, 48 BlnI, and 80 XbaI-BlnI distinct pulsotypes, suggesting several clones circulating through the food chain and multiple sources of transmission. Submission to the PulseNet Europe database indicated that PFGE profile SENTXB.0001, the most common PFGE profile in Europe, was also predominant in Greece (33.3 %). MLST showed that all the strains studied shared the same sequence type (ST11), representing the most common ST in Europe. High rates of resistance to nalidixic acid were observed among human and poultry isolates (~25 %), indicating the potential fluoroquinolone treatment failure. Our data suggest that strains originating from multiple reservoirs circulated in Greece through the food chain during the study period. Predominant profiles in Greece were common to PulseNet Europe profiles, indicating similarities between the S. Enteritidis populations in Greece and Europe. PMID:26864044

    2011-01-01

    Full Text Available One of the most distressing aspects of dentistry for pediatric patients is the fear and anxiety caused by the dental environment, particularly the dental injection. The application and induction of local anesthetics has always been a difficult task, and this demands an alternative method that is convenient and effective. Electronic dental anesthesia, based on the principal of transcutaneous electric nerve stimulation (TENS, promises to be a viable mode of pain control during various pediatric clinical procedures. Therefore, the aim of the present study was to evaluate the effectiveness of TENS and to compare its efficacy with 2% lignocaine during various minor pediatric dental procedures. Pain, comfort and effectiveness of both the anesthetics were evaluated using various scales and no significant difference was observed between 2% lignocaine and TENS in the various pain scales, while TENS was perceived to be significantly effective in comfort and efficacy as judged by the operator and quite comfortable as judged by the patient himself/herself.

    Historically varicocele is diagnosed almost exclusively on the left side. The introduction of new imaging techniques has allowed the identification and characterization of right varicocele. This study aims to compare the diagnostic accuracy of various imaging techniques to data obtained using phlebography in the diagnosis of right varicocele. Patients treated for isolated right varicocele between 1992 and 2010 were retrospectively identified. Data from clinical examination, Doppler-USS, Color-Doppler-USS and Retrograde Phlebography were collected for each patient. 133 out of 4305 patients (3.1%) presented with an isolated right varicocele. 34 of these patients (25.6%) presented with palpable right varicocele. Doppler-USS identified various degrees of type I right venous reflux in 90 patients (67.7%). Phlebography showed venous reflux in all the patients (133), although with variability in terms of internal spermatic vein anatomy. Right varicocele is characterized by predictable anatomic features. Identification and characterization of these features is useful in guiding percutaneous treatment, allowing to optimize radiological display and reducing failure rate.

    Full Text Available Purpose: The aim of the present study was to compare the periosteal fenestration (PF and free mucosal graft (FMG techniques in mandibular anterior region to increase the vestibular depth. Methodology: A total of 20 systemically healthy cases (10 patients in each group with shallow vestibular depth and reduced width of attached gingiva in lower anterior region were included in the present study. Clinical parameters recorded included Gingival index (GI, Plaque index (PI, Oral hygiene index simplified (OHI S, Vestibular depth (VD, width of attached gingiva and post operative discomfort. Findings: The results at the end of 3 months showed that the mean GI, PI, OHI S decreased significantly and remained low throughout the study period. The mean gain in percentage of vestibular depth at the end of 3 months for group 1(PF was 48.4% with relapse of 7.2% from the baseline. For group 2 (FMG, the mean gain in percentage of vestibular depth at the end of 3 months for was 50% with relapse of 6.2% from the baseline. The mean gain in percentage of attached gingiva at 3 months for group 1 and 2 was 65.9% and 74%, respectively. In comparison of group 1 and 2, group 2 showed better results in terms of increasing the vestibular depth and attached gingiva than group 1 although the intergroup comparison was not statistically significant. Conclusion: When aim of the clinician is to treat a patient with shallow vestibule together with reduced width of attached gingiva, the use of periosteal fenestration yields similar results to that of FMG.

This study compares experiences and understanding of patients reviewed via the virtual clinic versus the standard clinic by way of an extended patient satisfaction questionnaire (PSQ.Patients and methods: One hundred PSQs were given to consecutive patients attending glaucoma clinics in October 2013. All 135 patients reviewed via the virtual clinic from April 2013 until August 2013 were sent postal PSQs in September 2013. Data were obtained for demographics, understanding of glaucoma, their condition, satisfaction with their experience, and quality of information. Responses were analyzed in conjunction with the clinical records.Results: Eighty-five percent of clinic patients and 63% of virtual clinic patients responded to the PSQ. The mean satisfaction score was over 4.3/5 in all areas surveyed. Virtual clinic patients’ understanding of their condition was very good, with 95% correctly identifying their diagnosis as glaucoma, 83% as ocular hypertension and 78% as suspects. There was no evidence to support inferior knowledge or self-perceived understanding compared to standard clinic patients. Follow-up patients knew more about glaucoma than new patients. Over 95% of patients found our information leaflet useful. Forty percent of patients sought additional information but less than 20% used the internet for this.Conclusion: A substantial proportion of glaucoma pathway patients may be seen by non-medical staff supervised by glaucoma specialists via virtual clinics. Patients are accepting of this format, reporting high levels of satisfaction and non

    Full Text Available Abstract Background Foot problems in general and forefoot problems in particular can lead to a decrease in mobility and a higher risk of falling. Forefoot problems increase with age and are more common in women than in men. Around 20% of people over 65 suffer from non-traumatic foot problems and 60% of these problems are localised in the forefoot. Little is known about the best way to treat forefoot problems in older people. The aim of this study is to compare the effects of two common modes of treatment in the Netherlands: shoe advice and podiatric treatment. This paper describes the design of this study. Methods The study is designed as a pragmatic randomised clinical trial (RCT with 2 parallel intervention groups. People aged 50 years and over who have visited their general practitioner (GP with non traumatic pain in the forefoot in the preceding year and those who will visit their GP during the recruitment period with a similar complaint will be recruited for this study. Participants must be able to walk unaided for 7 metres and be able to fill in questionnaires. Exclusion criteria are: rheumatoid arthritis, neuropathy of the foot or pain caused by skin problems (e.g. warts, eczema. Inclusion and exclusion criteria will be assessed by a screening questionnaire and baseline assessment. Those consenting to participation will be randomly assigned to either a group receiving a standardised shoe advice leaflet (n = 100 or a group receiving podiatric treatment (n = 100. Primary outcomes will be the severity of forefoot pain (0-10 on a numerical rating scale and foot function (Foot Function 5-pts Index and Manchester Foot Pain and Disability Index. Treatment adherence, social participation and quality of life will be the secondary outcomes. All outcomes will be obtained through self-administered questionnaires at the start of the study and after 3, 6, 9 and 12 months.

    Mridula V Amarnath, Christina Samuel, Sundararajan D

    2015-01-01

    Full Text Available Background: Intraocular pressure (IOP is the fluid pressure inside the eye and is maintained by the equilibrium between the forces determining the formation of aqueous humour and the alteration in the resistance to its outflow. IOP is important to evaluate patients who are at an increased risk of glaucoma. Clinically measurement of IOP is based on principles of indentation and applanation and such a method is called Tonometry. The tonometers used today are the Schiotz Indentataion Tonometer (ST and the Goldmann’s Applanation Tonometer (GAT. However the latter is accepted as the standard one. Aim: 1 To estimate the normal mean IOP for the population under study.2 To study the various factors- age, sex, refractive errors that influence the IOP.3 Merits and demerits of the individual tonometers. Method: A sample size of 100 cases of 200 sets of eyes was taken and divided into 2 groups, Group A with emmetropia, myopia, hypermetropia of both sexes and Group B with frank glaucomatous changes of both sexes. 3 consecutive measurements with GAT were recorded in each eye followed by ST with 5.5gm weight first followed by ST with 7.5gm weight. The whole database was recorded and statistically analysed. Results: Out of the total 200 eyes studied, Group A consisted of 168 apparently normal eyes which included emmetropes, myopes and hypermetropes and Group B comprised of 32 eyes which were frank glaucomatous cases with glaucomatous field defects. On estimating the mean IOP with the help of GAT and ST between the 2 eyes there was not a significant difference. On comparing the refractive status, myopes showed a higher IOP than hypermetropes and emmetropes. With both GAT and ST females had higher IOP than males. The mean IOP increased as age progressed. Group B studies which had frank glaucoma cases showed that the IOP measured with GAT was higher and more accurate to the actual IOP value whereas the readings with Schiotz were variable and unreliable

    Full Text Available The clinical effect and safety of the anterior surgical approach and posterior surgical approach in the treatment of thoracolumbar spinal fracture was compared. Retrospective analyses of clinical data for 91 patients observed from March 2010 to September 2014 were made. The pre-operation and post-operation comparisons between two sets of Cobb’s angle, affected vertebra height, Frankel’s classification of spinal nerves, motion functions, and tactile functions showed statistically significant differences (P<0.05. After having the operation, the Cobb’s angle and affected vertebra height of the patient in the anterior approach group were both significantly higher than that of patients in the posterior approach group (P<0.05. The bone graft fusion rate of the patients in the anterior approach group 3 months after operation was higher than that of patients in the control group while the status of complications was worse than that of patients in the posterior approach group, both with a remarkable difference (P<0.05. Both the anterior surgical approach and posterior surgical approach have good clinical outcome for spinal fractures but they all have their respective adaption diseases. The key in the treatment of thoracolumbar spinal fractures lies in choosing proper operative approach.

    AIM To evaluate the clinical and optical outcomes after clear corneal incision cataract surgery (CICS) with three different incision sizes (1.8, 2.0 and 3.0 mm). METHODS Eyes of 150 patients with age-related cataract scheduled for coaxial cataract surgery were randomized to three groups: 1.8, 2.0, or 3.0 mm CICS. Intraoperative data and postoperative outcomes including surgically induced astigmatism (SIA), the corneal incision thickness, wavefront aberrations and modulation transfer function (MTF) of cornea were obtained. RESULTS There were no significant differences among the three groups in demographic characteristics and intraoperative outcome. The 1.8 and 2.0 mm microincisions showed more satisfactory clinical outcomes than the 3.0 mm incision. The 1.8 mm incision showed significantly less SIA than the 2.0 mm incision until postoperative 1mo (P0.05). CONCLUSION Converting from 3.0 mm CICS to 1.8 or 2.0 mm CICS result in better clinical and optical outcomes. However, when incision is 1.8 mm, the benefits from further reduction in size compared with 2.0 mm are limited. The necessity to reduce the incision size is to be deliberated. PMID:27158610

    The purpose of this work was to compare sequential (SeqB) versus simultaneous integrated boost (SIB) radiotherapy plans delivered with volumetric modulated arc therapy (VMAT) for patients with locally advanced squamous cell cancer of the head and neck (HNSCC). SeqB and SIB plans using VMAT for 10 HNSCC patients given definitive chemoradiation were generated and analysed for differences in dose distribution, coverage, conformity and homogeneity to the planning target volumes (PTV) 1-3 and sparing of organs at risk (OAR). The mean delineated volumes ± standard deviations were 137.7 ± 44.8, 351.3 ± 83.9 and 895.6 ± 120.5 cm{sup 3} for PTV1-3. The mean volumes encompassed by the corresponding 95 % isodoses were 281 (+ 110 %) ± 73.4, 712.2 (+ 115 %) ± 146.4 and 1381.1 (+ 54 %) ± 217.3 cm{sup 3} with SeqB and 138.2 (+ 7 %) ± 40.1, 380.4 (+ 11 %) ± 91.9 and 1057.3 (+ 21 %) ± 161.4 cm{sup 3} with SIB for PTV1-3, respectively. Both strategies achieved excellent PTV coverage. SeqB provided significantly better coverage of PTV1 and 3, worse conformity for PTV1-3 and a higher mean dose than prescribed (111-115 %) to PTV2 and 3 (p ≤ 0.007). Both strategies provided satisfactory OAR sparing. This study showed significant dosimetric differences with potential clinical relevance between two VMAT boost strategies regarding coverage, conformity and dose to the PTVs. SIB might cause less toxicity. A clinical phase III/IV trial endorsed by the German Head and Neck Clinical Trials Group (IAG-KHT) will evaluate differences in acute/late toxicity as well as in locoregional recurrences between the two boost techniques.

    2008-06-01

    There is a lack of consensus surrounding the conceptualization of narcissism. The present study compared two measures of narcissism-one used in clinical settings (Personality Diagnostic Questionnaire, PDQ-4+; Hyler, 1994) and one used in social-personality research (Narcissistic Personality Inventory, NPI; Raskin & Terry, 1988)-across two samples. Sample 1 (N=271) was composed of undergraduates, whereas Sample 2 (N=211) was composed of parents of the Sample 1 participants. The scales were significantly interrelated but manifested divergent relations with general personality traits, personality disorders (including expert prototypal ratings of narcissism), recollections of parenting received, and psychological distress and self-esteem. PDQ-4 narcissism captured an emotionally unstable, negative-affect-laden, and introverted variant of narcissism; NPI narcissism captured an emotionally resilient, extraverted form. The clinical and social-personality conceptualizations of narcissism primarily share a tendency to use an antagonistic interpersonal style. Implications for the DSM-V are discussed. PMID:18399956

    fulfilling the predetermined inclusion and exclusion criteria were included in the study. STATISTICAL METHODS : Intergroup comparison was analysed by K - Independent sample t test. Intragroup comparison was analysed by Paired t - test. RESULTS : Patients were divided into two groups and treated with using Bone - patellar tendon - bone graft and Hamstring graft respectively. Mean age group of patients was 29.16 yrs. (range 16 - 51yrs and 30.88 yrs. (range 19 - 48yrs in group A and B respectively we found the incidence of ACL injury in 15 - 44 years age group to be greater than twice the general population. A mean delay in surgery of 4.66 months (range 2 - 12 months since the time of injury in group A and 4.46 months (range 2 - 7 months in group B was observed. Subjective IKDC evaluation was done at the end of 12 months. Ther e was no difference in both the groups in the terms of effusion, passive motion, knee compartment findings, ligament examination, X - ray findings. Functional test and IKDC grade of both the groups showed statistically very highly significant improvement. Ho wever, there was statistically very high Harvest site pathology in group A. CONCLUSION : We found that there is statistically no significant difference in the overall clinical outcome between hamstring autograft with transfix and bone - patellar tendon bone autograft with interference screw except that the patellar tendon group had a greater tendency of having donor site morbidity compared to the hamstring tendon group.

  7. The clinical efficacy of methotrexate and 5-fluorouracil in the interventional treatment of uterine incisional pregnancy after cesarean section: a comparative study

    International Nuclear Information System (INIS)

    Objective: To compare the interventional therapeutic efficacy of methotrexate (MTX) with that of 5-fluorouracil (5-FU) in treating uterine incisional pregnancy after cesarean section. Methods: A total of 92 patients with uterine incisional pregnancy after cesarean section, who were admitted to the hospital during the period from 2007 to 2010, were randomly divided into two groups: group MTX and group 5-FU. Patients in group MTX (n=46) received intra-arterial infusion of MTX (60-200) mg, which was followed by arterial embolization. Patients in group 5-FU (n=46) received intra-arterial infusion of 5-FU (1000-1250) mg, which was followed by arterial embolization. After the treatment the serum β-HCG and progesterone levels were determined daily for three succeeding days. The patients were followed up for three months. The clinical results were compared between the two groups. Results: The cure rates in group MTX and group 5-FU were 97.2% and 100%, respectively. No significant difference in cure rate existed between the two groups (P>0.05). A rapid fall in the serum β-HCG and progesterone levels within 1-3 days after the treatment were detected in 40 cases of group MTX and 38 cases of group 5-FU, and the decreasing extent was over 50%-80%, but the difference between the two groups was not significant (P>0.05). At the operation day, all patients of both groups had abdominal pain, and three patients in group MTX and 2 patients in 5-FU group had nausea and vomiting, but the difference between the two groups was not significant (P>0.05). During the follow-up period, no significant difference in the recovery time of the mental cycle and the hormone levels were found between the two groups (P>0.05). Conclusion: For the interventional treatment of uterine incisional pregnancy after cesarean section, the use of MTX has the same clinical efficacy as the use of 5-FU does. (authors)

    Prostacyclin (PGI2) and its mimetics (iloprost, treprostinil, beraprost and MRE-269) are potent vasodilators (via IP-receptor activation) and a major therapeutic intervention for pulmonary hypertension (PH). These PGI2 mimetics have anti-proliferative and potent vasodilator effects on pulmonary vessels. We compared the relaxant effects induced by these recognized IP-agonists in isolated human pulmonary arteries (HPA) and veins (HPV). In addition, using selective antagonists, the possible activation of other prostanoid relaxant receptors (DP, EP4) was investigated. Iloprost and treprostinil were the more potent relaxant agonists when both vessels were analyzed. HPA were significantly more sensitive to iloprost than to treprostinil, pEC50 values: 7.94±0.06 (n=23) and 6.73±0.08 (n=33), respectively. In contrast, in HPV these agonists were equipotent. The relaxations induced by treprostinil were completely or partially inhibited by IP-antagonists in HPA or HPV, respectively. The effects of the IP-agonists were not significantly modified by the EP4 antagonist. Finally, DP-antagonists inhibited the relaxations induced by treprostinil in HPV, suggesting that the DP-receptor plays a role in treprostinil-induced relaxation in the HPV. These data suggest that iloprost and treprostinil should be the most effective clinically available agonists to decrease pulmonary vascular resistance and to prevent oedema formation (by similar decrease in HPA and HPV resistance) in PH patients.

    Full Text Available Spinal anaesthesia requires a small volume of drug to produce profound sensory analgesia and motor blockade but has limited duration of action. So a properly chosen adjuvant to local anaesthetic agent produces the best way to achieve a better quality regional block. Hence the present study was undertaken to compare the effects of intrathecal clonidine (30μg and pla cebo, when administered together with hyperbaric bupivacaine 0.5% for major gynaecological surgeries like Total Abdominal hysterectomy, vaginal hysterectomy, and Manchester repair.100 patients posted for elective major gynaecological surgeries were selecte d and allocated randomly into two groups. Each group of 50 patients. Group I : - 0.5% of Hyperbaric Bupivacaine (17.5mg + placebo Group II: - 0.5% of Hyperbaric Bupivacaine (17.5mg + clonidine(30μg. Onset of sensory block, motor block, quality of analgesi a, duration of analgesia and duration motor blockade between two groups were compared and contrasted. Patient vitals like Pulse rate, Blood pressure, Respiratory rate, SPO 2 and ECG were monitored during the study. During the study observed for the side eff ects like Nausea, Vomiting, Hypotension, Bradycardia, and dryness of mouth. CONCLUSIONS : A re Quality of analgesia is excellent in patients receiving clonidine when compared to placebo group. Total duration of analgesia and motor blockade was significantly prolong in clonidine group compared to placebo group. Minimal side effects like mild hypotension, mild sedation, and dryness of mouth were seen in clonidine group which does not require any active intervention.

    Full Text Available Aim: To compare the efficacy of oral lycopene and injection betamethasone with control group in the management of oral submucous fibrosis. Materials and Methods: A hospital based longitudinal study, conducted on 270 patients over a period of 2 years (September 2010-September 2012. Results: Out of 270 cases 223 (82.59% were males and 47 (17.40% were females which showed a male predominance and the ratio was 5:1. In stage I it was found that both the test groups, i.e., injection betamethasone and capsule lycopene had a significant improvement in mouth opening than control group. In stage II, it was found that the test group injection betamethasone showed 24 better results as compared to capsule lycopene this could be because of better accessibility of the fibrotic bands for injecting betamethasone solution at the site of the lesion and showed highly significant difference (P < 0.0001. In stage III, it was found that the capsule lycopene showed better results as compared to injection betamethasone and the difference was highly significant (P < 0.0001. This could be because of restricted mouth opening and inability to reach the site for injecting betamethasone solution. Conclusion: It is evident from the study that capsule lycopene and injection betamethasone hold good promise in the treatment of this multifactorial crippling disease.

  15. Clinical Studies with Epothilones

    Altmann, Karl-Heinz

    As indicated in previous chapters, epothilone research so far has delivered seven new chemical entities that have been advanced to clinical trials in humans (Fig. 1). However, the amount of clinical data publicly available at this time strongly varies between individual compounds, depending on their development stage, but also on the general publication policy of the developing company. The compound that has been most comprehensively characterized in the clinical literature is ixabepilone (BMS-247550), for which trial results have been described in a number of articles in peer-reviewed journals and which has been granted FDA approval for two clinical indications on Oct. 16, 2007. For all other compounds, most of the information on clinical trials is available only in abstract form. In all these cases it remains uncertain, whether the content of these abstracts fully reflects the content of the subsequent (poster or oral) presentations at the corresponding meeting; in fact, it seems likely that additional data will have been included in the actual meeting presentations that may not have been available at the time of abstract submission. As this is unknown to the author, such additional information cannot be considered in this chapter, which is solely based on information documented in accessible abstracts or journal publications. It should also be kept in mind that the interpretation of data from ongoing clinical trials or forward looking statements based on data from completed trials are always preliminary in character.

    Naja naja (Indian cobra) from Sri Lanka and India is the WHO Category 1 medically important snakes in both countries. Some antivenom produced against Indian N. naja (NNi) were less effective against Sri Lankan N. naja (NNsl). Proteomes of NNi and NNsl venoms were studied by RP-HPLC, SDS-PAGE and LC/MS/MS. Six protein families were identified in both venoms with the most abundant were the 3 finger toxins (3FTs) where cytotoxins (CTX) subtype predominated, followed by phospholipase A2, cysteine-rich venom protein, snake venom metalloproteases, venom growth factors, and protease inhibitors. Qualitative and quantitative differences in the venomics profiles were observed. Some proteins were isolated from either NNi or NNsl venom. Postsynaptic neurotoxins (NTX) were identified for the first time in NNsl venom. Thus, there are geographic intra-specific variations of venom composition of the two N. naja. The relative abundance of CTX and NTX explained well the clinical manifestations of these venoms. Antivenomics study of an Indian antivenom (Vins) showed the antibodies effectively bound all venom toxins from both snakes but more avidly to the Indian venom proteins. The lower antibody affinity towards the 'heterologous' venom was the likely cause of poor efficacy of the Indian antivenom used to treat NNsl envenoming. PMID:26506536

  17. Clinical comparative study between the use of lasers and conventional methods of diagnosis and treatment in deciduous teeth with presence of carious lesion

    International Nuclear Information System (INIS)

    The aim of this work was to evaluate the efficiency of deciduous tooth cavity preparation by the Er:YAG laser in comparison with the conventional burr rotary instrument. Besides, we have used the laser fluorescence technique (DIAGNOdent equipment) for diagnosis and compared it to the usual tactile and visual examination as well as X-ray diagnosis. For this purpose, 20 chronic occlusal carious deciduous molar teeth from children with the ages between 5 to 10 years old were selected. Selection was ma de according to visual inspection, X-ray periapical image and measures of the DIAGNOdent. For treatment the teeth were divided in two groups, 10 to be treated by the Er:YAG laser and 10 with conventional burr. For enamel, the laser energy used was in the interval from 200 to 300 mJ; for the dentine the range was from 100 mJ to 200 mJ. In both cases, the laser frequency was in the range from 2 to 4 Hz. The results have shown that the laser treatment was more accepted by the children than the conventional burro Clinical evaluation of the cavity preparation indicates that the Er:YAG laser treatment is recommend. The DIAGNOdent evaluation method was very effective for diagnosis of carious tissue for initial detection. After successful removal of the carious tissue, confirmed by visual inspection, the DIAGNOdent evaluation method was only effective for the treatment with conventional burro For evaluation of the tooth after cavity preparation with the Er:YAG laser, the measurements oscillate covering the full range of the equipment. Therefore, the use of the DIAGNOdent equipment is indicated only for initial caries diagnosis. (author)

  20. Comparative study on the clinical outcomes of direct PTA and intravenous rtPA thrombolytic therapy for acute cerebral ischemic stroke

    International Nuclear Information System (INIS)

    The outcomes of direct percutaneous transluminal angioplasty (PTA) and intravenous recombinant tissue plasminogen activator (rtPA) were compared in the treatment of acute cerebral infarction. The comparative study was conducted on 25 consecutive cases treated by direct PTA before October 2005 and 25 cases treated by intravenous rtPA between October 2005 and March 2007. In the treatments with direct PTA for acute cerebral arterial occlusion, the blood clot was broken up with a balloon using MRI and MR angiography (MRA) as an indication, and urokinase was administered. In the direct PTA treatment group, the recanalization rate was 88%, the good outcome rate (mRS 0-2) was 52%, and the bleeding complication rate was 16%. In the intravenous rtPA group, on the other hand, comparable results were obtained with a good outcome rate (mRS 0-2) of 56% and a bleeding complication rate of 12%. The recanalization rate was higher in the direct PTA group, while the outcome and the complication rate were similar to those in the intravenous rtPA group. These findings suggest that the time elapsed after stoke until recanalization, rather than the recanalization rate, represents an important prognostic determinant in acute cerebral arterial occlusive diseases.

    Full Text Available Background: Calcium sodium phosphosilicate is a recently introduced desensitizing agent which acts by occluding the dentinal tubules and also resists acid decalcification. This study was designed to assess the efficacy of a new toothpaste containing 5% calcium sodium phosphosilicate for the treatment of dentinal hypersensitivity and also compare it with 5% potassium nitrate. Materials and Methods: Sixty patients with the chief complaint of dentinal hypersensitivity were enrolled and randomly divided into two groups. The visual analog scale (VAS scores were taken for water and air stimuli at baseline, 3 weeks after usage of the respective toothpaste, and 3 weeks after discontinuation of the respective toothpaste. Results: Both the groups showed reduction in hypersensitivity scores at 3 weeks and 6 weeks for air stimulus and cold water. The calcium sodium phosphosilicate group, however, showed significantly reduction in hypersensitivity compared to the potassium nitrate group at any time point for both measures of hypersensitivity. Conclusion: The 5% calcium sodium phosphosilicate group showed immense reduction in dentinal hypersensitivity symptoms. The 5% calcium sodium phosphosilicate showed prolonged effects even after discontinuation as compared to 5% potassium nitrate, due to its dentinal tubular occlusion property.

The biodistribution of both preparations was examined in experimental animals at different time intervals, from 15 min to 4 hr; the percentage of incorporation of sup(99m)Tc-DMS into kidneys is much higher (29-4% to 52.0%) than that of sup(99m)Tc-GH (12.80% to 22.20%). Both preparations accumulate to a greater extent in the renal cortex than in the medulla. The most suitable time for renal scintigraphy for sup(99m)Tc-DMS is 90-150 min while for sup(99m)Tc-GH it is 60-90 min. It is concluded that sup(99m)Tc-DMS is more suitable for static scintigrams on the scanner and sup(99m)Tc-GH for dynamic studies with the gamma camera. (orig.)

    Full Text Available Background: Gingival recession (GR can result in root sensitivity, esthetic concern to the patient, and predilection to root caries. The purpose of this randomized clinical study was to evaluate (1 the effect of guided tissue regeneration (GTR procedure using a bioabsorbable collagen membrane, in comparison to autogenous subepithelial connective tissue graft (SCTG for root coverage in localized gingival recession defects; and (2 the change in width of keratinized gingiva following these two procedures. Materials and Methods: A total of 10 cases, showing at least two localized Miller′s Class I or Class II gingival recession, participated in this study. In a split mouth design, the pairs of defects were randomly assigned for treatment with either SCTG (SCTG Group or GTR-based collagen membrane (GTRC Group. Both the grafts were covered with coronally advanced flap. Recession depth (RD, recession width (RW, width of keratinized gingiva (KG, probing depth (PD, relative attachment level (RAL, plaque index (PI, and gingival index (GI were recorded at baseline, 3 and 6 months postoperatively. Results: Six months following root coverage procedures, the mean root coverage was found to be 84.84% ± 16.81% and 84.0% ± 15.19% in SCTG Group and GTRC Group, respectively. The mean keratinized gingival width increase was 1.50 ± 0.70 mm and 2.30 ± 0.67 mm in the SCTG and GTRC group, respectively, which was not statistically significant. Conclusion: It may be concluded that resorbable collagen membrane can be a reliable alternative to autogenous connective tissue graft in the treatment of gingival recession.

    A 2-week study was conducted to compare the tooth-whitening efficacy of two 10% carbamide peroxide products: Colgate Platinum Professional Toothwhitening System and Rembrandt Lighten Bleaching Gel. Fifty subjects were divided into two groups and assigned a product to use for 2 weeks. Change in tooth color was measured by reflectance spectroscopy at the initiation of study, at 1 week, and at 2 weeks into the study. Color change was calculated using the color-difference equation established by the Commission International de L'Eclairage. Results showed that Colgate Platinum was 62% more effective at tooth whitening after 1 week and 83% more effective after 2 weeks of treatment vs Rembrandt. At the termination of the study, the mean color difference (deltaE) for Colgate Platinum was 4.29 and 2.34 for Rembrandt. Statistical analysis demonstrated that the Colgate product is significantly superior at increasing tooth whiteness, increasing tooth lightness, reducing redness, and reducing yellowness. In this study, no adverse reactions were noted on clinical examination and none were reported by panelists with normal healthy dentition. PMID:8205580

    Objective: China introduced a series of health reforms in 2009, including a national essential medicines policy and a medical insurance system for primary care institutions. This study aimed to determine the changing prescribing patterns associated with those reforms in township hospitals. Methods: A multi-stage stratified random cluster sampling method was adopted to identify 29 township hospitals from six counties in three provinces. A total of 2899 prescriptions were collected from the participating township hospitals using a systematic random sampling strategy. Seven prescribing indicators were calculated and compared between 2008 and 2013, assessing use of medicines (antibiotics and adrenal corticosteroids) and polypharmacy, administration route of medicines (injections), and affordability of medicines. Results: Significant changes in prescribing patterns were found. The average number of medicines and costs per-prescription dropped by about 50%. The percentage of prescriptions requiring antibiotics declined from 54% to 38%. The percentage of prescriptions requiring adrenal corticosteroid declined from 14% to 4%. The percentage of prescriptions requiring injections declined from 54% to 25%. Despite similar changing patterns, significant regional differences were observed. Conclusions: Significant changes in prescribing patterns are evident in township hospitals in China. Overprescription of antibiotics, injections and adrenal corticosteroids has been reduced. However, salient regional disparities still exist. Further studies are needed to determine potential shifts in the risk of the inappropriate use of medicines from primary care settings to metropolitan hospitals. PMID:27399732

A significantly higher proportion of patients achieved 1998 EAS low-density lipoprotein cholesterol (LDL-C goal after 12 weeks of treatment with rosuvastatin 10 mg compared to simvastatin 20 mg (64 vs 51.5%, p < 0.01. Similarly, significantly more patients achieved the 1998 EAS total cholesterol (TC goal and the 2003 EAS LDL-C and TC goals (p < 0.001 with rosuvastatin 10 mg compared with simvastatin 20 mg. The incidence of adverse events and the proportion of patients who discontinued study treatment were similar between treatment groups. In conclusion, in the DISCOVERY-Beta Study in patients with primary hypercholesterolemia greater proportion of patients in the rosuvastatin 10 mg group achieved the EAS LDL-C treatment goal compared with the simvastatin 20 mg group. Drug tolerability was similar across both treatment groups.Keywords: hypercholesterolemia, low-density lipoprotein

    International Nuclear Information System (INIS)

    Objective: To compare the imaging findings of CT non-contrast (CTNOC) and CT-myelography (CTM) in lumbar intervertebral disk, the authors proposed a new concept of intervertebral disk-flavum ligamentum space (DFLS), analyzed the causes of stenosis in lumbar DFLS and evaluated its diagnostic value in compressed lumbar radiculopathy. Methods: The images of CTNOC and CTM of 83 cases were retrospectively analyzed, and the shapes of L3-S1 disk, the width of flavum ligament at each side, the degree of prominence interior of the joint process superior at each side, and the sagittal diameter of the dural sac in L3-S1 were recorded. The relation of these restrictions and parameters to DFLS stenosis and the compressed lumbar nerve roots shown in CTNOC and CTM were analyzed. Results: The herniation of intervertebral disk were found in 138 level with the diameter of the corresponding dural sac 5 mm; 67 joint process superior prominent interior > 2 mm; 157 of 83 cases of mean width DFLS 3.8 mm. Conclusion: The DFLS≤5 mm can be diagnosed as stenosis. The main causes of stenosis are the herniation of intervertebral disk, flavum ligament thicker; and joint process superior prominent interior. It can be used as a valuable criterion in diagnosing lumbar nerve root compression in CT study

    A comparative study was made by the double-blind technique in order to make clear the usefulness of pivmecillinam in the treatment of intractable complicated urinary-tract infections using amoxicillin as a reference drug. Pivmecillinam was given in dosage of 400 mg (potency) per day which was one-fifth the dose of amoxicillin 2,000 mg (potency) per day. In global judgement, pivmecillinam was found superior to amoxicillin. It showed a "significant" superiority over amoxicillin for the treatment of, among others, the urinary-tract infections after prostatectomy, which are intractable diseases. When evaluated by symptoms, pivmecillinam improved bacteriuria "significantly" better than amoxicillin. When seen by causative organisms, the pivmecillinam treatment was "significantly" superior to the amoxicillin treatment against E. coli infections. Pivmecillinam was active against amoxicillin-resistant E. coli. Incidence of adverse reactions was less frequent with pivmecillinam than with amoxicillin. These results indicate that pivmecillinam is a drug of high usefulness for the treatment of intractable complicated urinary-tract infections when evaluated using amoxicillin as a reference drug.

The time taken to intubate (TTI and participants′ rating of the ease of use was recorded on a scale of 1-10 (10-most difficult. Results: In Group NTI, there was no difference in mean TTI with the three scopes (P = 0.938. In Group NVL, TTI was longer with the VLs than MAC (P < 0.001. In Group EXP, TTI with VL took 20 s more (P < 0.001. There was significant difference in participants′ rating of ease of use of laryngoscope in Group NVL (P = 0.001 but not in the NTI (P = 0.205, EXP (P = 0.529 groups. A high failure was seen with MGR in Group NTI and NVL. Conclusion: In Group NTI, TTI and the ease of use were similar for all scopes. Expertise with standard direct laryngoscopy does not translate to expertise with VLs. Separate training and experience with VLs is required.

  1. Clinical studies on cerebral infarction

    International Nuclear Information System (INIS)

    Hemorrhagic infarction (HI) is termed as the infarction in which a large part of the necrotic tissue is stippled with small hemorrhage. The pathogenetic mechanism of this disease still remains controversial. Cerebral infarction has long been divided into two subtypes-thrombosis and embolism-according to the pathogenetic mechanisms. Clinical studies were carried out in 31 cases of HI with cerebral thrombosis. CT findings of these cases were classified into five groups according to both size of low density area which indicates regions of infarction and distribution of arterial supply. The low density area of Type I-Type III were observed in the area of the middle cerebral artery. That of Type IV was observed in the area of the internal capsule and basal ganglia. That of Type V was observed in the area of the posterior cerebral artery. CT reveals two patterns of HI -pattern A and pattern B-. The CT finding of pattern A is appearance of high density area in the low density area. The CT finding of pattern B is appearance of iso density area in the low density area. rCBF was measured by 133Xe inhalation technique in 21 patients with CT type I, II and III. Thereafter, with regard to the various findings in CT, the clinical findings and CBF findings, a comparative study was carried out on these ten groups. From the results of present studies, it is concluded that sequential changes of CBF in cases with pattern A are different from those with pattern B, and that CBF measurement does not permit an estimation of a patient's chance for functionary recovery after a stroke in acute and subacute stage but permits estimation of functional outcome in chronic stage.

Materials and Methods: A total of 20 sites from 10 systemically healthy patients were selected for the study. The selected sites were randomly divided into experimental site A and experimental site B by using the spilt mouth design. Conventional (macro-surgical approach for site A and micro-surgery for site B was applied in performing the free rotated papilla autograft combined with coronally advanced flap. Recession depth (RD, recession width (RW clinical attachment level (CAL. and width of keratinized tissue (WKT. were recorded at baseline, 3 months and 6 months post-operatively. Results: Both (macro- and microsurgery groups showed significant clinical improvement in all the parameters (RD, RW, CAL and WKT. However, on comparing both the groups, these parameters did not reach statistical significance. Conclusion: Both the surgical procedures were equally effective in treatment of localized gingival recession by the free rotated papilla autograft technique combined with coronally advanced flap. However, surgery under magnification (microsurgery may be clinically better than conventional surgery in terms of less post-operative pain and discomfort experienced by patients at the microsurgical site.

  7. Effects of low-energy laser irradiation on the distalization velocity during experimental canine tooth movement in humans: 'comparative clinical study'

    International Nuclear Information System (INIS)

    This research investigated the effects of low level laser therapy (LLLT) upon the velocity of canine tooth movement and consequently bone remodeling. A total of eleven patients were treated with a 780 nm diode laser. One side of the upper arcade was considered control group and was not irradiated but received mechanical activation every thirty days. The opposite side received the same mechanical activation but was also irradiated at days 0, 3, 7 and 14 of each month. Data of the biometrical progress were taken on both sides on days 3,7,14,21 and 30 of each month. The results indicate that all patients showed significant acceleration of the distalization velocity on the side treated with LLLT when compared to the control. (author)

    Full Text Available Background: Obtaining predictable and esthetic root coverage has become an important part of periodontal therapy. Several techniques have been developed to achieve these goals with variable outcomes. The aim of this study was to appraise the effectiveness of acellular dermal matrix allograft (ADMA and subepithelial connective tissue graft (SCTG compared to coronally advanced flap (CAF in the treatment of multiple gingival recessions. Materials and Methods: A total of 30 patients aged between 18 and 50 years, with multiple Miller's Class I and II recessions on labial or buccal surfaces of teeth were selected for this study. The patients were randomly assigned to CAF + ADMA, CAF + SCTG and CAF groups with 10 patients in each group. The clinical parameters assessed were probing pocket depth (PPD, clinical attachment level (CAL, gingival recession (GR, width of keratinized tissue, plaque index and papilla bleeding index at base line and 6 months after surgery. Results: Statistical analysis using One-way ANOVA suggested that the root coverage obtained was greater in the ADMA + CAF (89.83 ± 15.29%, when compared to SCTG + CAF (87.73 ± 17.63% and CAF (63.77 ± 27.12% groups. The predictability for coverage of> 90% was greater in CAF + ADMA (65% when compared with SCTG + CAF (61.66% and CAF (31.17%. Improvements in the clinical parameters from baseline were found in all the three groups treated. Conclusion: It was concluded that all three techniques could provide root coverage in Miller's class I and II gingival recessions; but greater % root coverage and predictability for coverage of> 90% could be expected with CAF + ADMA and CAF + SCTG groups when compared with CAF alone.

    Respiratory insufficiency commonly develops in patients with Late Onset Pompe Disease (LOPD). It is conceivable that a timely starting of enzyme replacement therapy could avoid this life-threatening complication. Respiratory function in LOPD is commonly evaluated with standard pulmonary tests which do not extensively provide an accurate definition of the muscular pathophysiology. In eleven patients with LOPD and five healthy subjects, we compared pulmonary function results with MRI data, based on scans of the right lung acquired on maximum expiration and inspiration. We observed that variations in the cranio-caudal lung height and of lung areas in inspiration and expiration (lung delta) as well as the area of diaphragmatic movement strongly correlated with pulmonary function results. Moreover, MRI data confirmed that development of respiratory insufficiency in LOPD is mainly due to the diaphragmatic weakness with sparing of the antero-posterior chest expansion related to the activity of the intercostal muscles. These results suggest that respiratory muscle MRI is a quick, useful and reproducible tool for patient management as well as a reliable outcome measure for future LOPD therapeutic trials.

    Full Text Available This prospective, randomized, double-blinded, placebo-controlled study in which 150 ASA I-II patients scheduled for middle ear surgery were randomized into three equal groups. The dexamethasone group (group D received a single dose of dexamethasone 10 mg IV at induction of anesthesia, ondansetron group (group O received 4 mg IV ondansetron and the control group (group C received 5 ml saline IV as placebo by the same technique. The study demonstrated that the incidence of early postoperative nausea, retching and vomiting (PONV was significantly greater in the placebo group than the dexamethasone group (P 0.05. More over, the severity of late PONV (6-24h was markedly less in the dexamethasone group than the ondansetron group (P< 0.05 and still the incidence of late PONV was markedly less in both dexamethasone and ondansetron groups than the control group (P< 0.001. The study also reported that postoperative analgesic requirement was notably lower in the dexamethasone group than the ondansetron and control groups. An experimental animal study was also done to assess the extrapyramidal reaction associated with the use of both dexamethasone and ondansetron. Increasing doses of both drugs were given IV to the rats, up to 5 times the therapeutic dose of each drug. The rats then stimulated for 24h after injection by light, sound and 6 volt electric current in the Rat Conditioning Chamber. No one rat developed akathisa or acute dystonic reaction. In conclusion, dexamethasone and ondansetron were quite effective and have limited side-effects profile when given as single prophylactic antiemetic doses in patients undergoing middle ear surgery. The advantages of dexamethasone over ondansetron were its prolonged antiemetic effect, its analgesic effect and the lower cost.

    Background: The University of Queensland (UQ), Ochsner Clinical School (OCS) is a partnership between Ochsner Health System in New Orleans, LA, and UQ in Brisbane, Australia. OCS medical students are trained on both continents, receiving their didactic education in Australia and their clinical education in the United States. Methods: We review the OCS experience and compare the pediatric rotations at OCS and UQ. Results: Students in the pediatric rotations in Australia and in the United States receive their clinical instruction in the real-world learning environment of hospitals and clinics. In addition, lectures, online learning modules, case-based tutorials, and rigorous assessment at the end of the rotation help prepare medical students for future contact with pediatric patients. Sixty-nine third-year OCS students and 499 fourth-year UQ students completed the pediatric rotation in 2014. In 2015, 105 third-year OCS students and approximately 400 fourth-year UQ students completed the pediatric rotation. Conclusion: In a unique educational collaboration, OCS has used e-learning and face-to-face tutorials to produce a well-rounded curriculum that assimilates global healthcare and international medicine. This article demonstrates the feasibility of delivering a standardized curriculum across two continents using modern e-learning tools. PMID:27046407

MATERIALS AND METHODS : In the study fifty adult patients of ASA - I or II physical status requiring intracranial surgeries unde r General Anesthesia were selected irrespective of sex and randomly allocated in two groups. In one Group the Circle absorption system and in another Group the Bain breathing system was used for delivery of the anesthetics and performance of IPPV. To avoid variation in observations same premedications, anaesthetic drugs and anaesthetic technique excepting the breathing system varying as per group were used in all the patients of both the groups. Circle absorption system was used with a fresh gas flow of 4.5 Liters and Bain breathing system was used with a fresh gas flow of 6 Liters for maintenance of anaesthesia and performance of IPPV. Pulse rate, SpO 2 , SBP, DBP and MAP were recorded before induction of Anaesthesia, during induction, after intubation, at th e time of incision and every 10mins thereafter till the time of reversal. EtCO2 and FiCO2 were recorded immediately after intubation, at the time of incision and every 10mins thereafter till the time of reversal. Desired level of EtCO2 was maintained by mo derate hyperventilation as and when required. Brain relaxation was graded in consultation with the surgeon and by simple visual assessment. RESULTS AND OBSERVATIONS: The study involved analysis of capnometric information acquired following use of both the breathing systems. The ability of both the breathing systems to effectively eliminate Carbon dioxide and their rebreathing characteristics were analyzed from the data obtained.

    Full Text Available Aim: The aim was to analyze general incidence, age incidence, laterality, common mode of presentation, staging of the tumor, radiological evidence, histopathological confirmation, management and follow-up of cases, which were diagnosed as retinoblastoma. Design: Interventional case series study from April 1997 to March 2000. Materials and Methods: Detailed history regarding the symptoms such as white reflex, watering, pain, redness, protrusion of eyeball, squint, hyphema, and defective vision were obtained. Family history regarding consanguinity between parents, health of the siblings and other relatives were recorded. Ocular examination included vision, pupillary reaction, detailed fundus examination, ocular tension, and corneal diameter. Investigations included X-ray orbit and skull, computed tomography scan orbit and brain, B-scan orbit, serum and aqueous lactate dehydrogenase; enucleated eyes were subjected to holoprosencephaly (HPE. Enucleation, radiotherapy, cryotherapy and chemotherapy were modalities of treatment. The empty socket and the other apparently normal eye were examined carefully at each visit. Results: The incidence of retinoblastoma is less when compared to other diseases of the eye. There was no sex predilection. Most of the cases diagnosed were sporadic and unilateral. Age of onset is earlier for bilateral cases than unilateral cases. Consanguinity bears close relationship with bilateral involvement. Predominant clinical sign is white reflex in the pupillary area. Majority of cases presented in the second stage of the disease. Enucleation plays a greater role in the management of retinoblastoma. HPE should include several sections of the optic nerve to find out skip lesions.

    Wilt, Timothy J

    2012-12-01

    Prostate cancer is the most common noncutaneous malignancy and the second leading cause of cancer death in men. In the United States, 90% of men with prostate cancer are more than age 60 years, diagnosed by early detection with the prostate-specific antigen (PSA) blood test, and have disease believed confined to the prostate gland (clinically localized). Common treatments for clinically localized prostate cancer include watchful waiting (WW), surgery to remove the prostate gland (radical prostatectomy), external-beam radiation therapy and interstitial radiation therapy (brachytherapy), and androgen deprivation. Little is known about the relative effectiveness and harms of treatments because of the paucity of randomized controlled trials. The Department of Veterans Affairs/National Cancer Institute/Agency for Healthcare Research and Quality Cooperative Studies Program Study #407:Prostate Cancer Intervention Versus Observation Trial (PIVOT), initiated in 1994, is a multicenter randomized controlled trial comparing radical prostatectomy with WW in men with clinically localized prostate cancer. We describe the study rationale, design, recruitment methods, and baseline characteristics of PIVOT enrollees. We provide comparisons with eligible men declining enrollment and men participating in another recently reported randomized trial of radical prostatectomy vs WW conducted in Scandinavia. We screened 13 022 men with prostate cancer at 52 US medical centers for potential enrollment. From these, 5023 met initial age, comorbidity, and disease eligibility criteria, and a total of 731 men agreed to participate and were randomized. The mean age of enrollees was 67 years. Nearly one-third were African American. Approximately 85% reported that they were fully active. The median PSA was 7.8ng/mL (mean 10.2ng/mL). In three-fourths of men, the primary reason for biopsy leading to a diagnosis of prostate cancer was a PSA elevation or rise. Using previously developed tumor risk

    Full Text Available Introduction: Ventilator-associated pneumonia (VAP is one of the most popular nosocomial infections in the intensive care units and the nurse’s role in preventing it is very important. The aim of this study was to compare the effect of two methods of face to face training and work- shop clinical guidelines in prevention of VAP. Methods: In this experimental randomized clinical trial, the knowledge and practice of nurses in ICUs were studied in two groups: face to face training (35 nurses and workshops (40 nurses by using clinical guidelines in prevention of VAP in one of the hospitals of Shiraz University of Medical Sciences. The level of knowledge and practice in each group was assessed by selfreport questionnaire, knowledge questionnaire and also direct observation of practice, before and after training. Data were analyzed with descriptive statistics, paired t-test, independent t-test, McNemar test, Fisher’s exact, sign and Chi-square test, using SPSS 14. Results: This study demonstrated that both methods of face to face training and workshop were very effective. The incidence of inappropriate pressure of cuff in the tracheal tubes and tracheostomy tubes was significantly reduced after training (p=0.001. But, by comparison of these two methods and the relationship between the variables revealed that no significant difference was found between the two groups of face to face training and workshop. Conclusion: Training the nurses is highly effective in preventing VAP, particularly for appropriate cuff pressure, suctioning and disinfecting hands.

    Full Text Available Background: Several modalities of treatment have been tried in vitiligo with varied results; however, Indian data on comparative studies of two or more therapies are limited. Aims: We compared different phototherapy methods with an oral steroid as an adjunct to determine the method with the best tolerability and efficacy. Methods: Eighty-six patients with progressive vitiligo were randomly assigned to different study groups according to a continuous selection method over a period of one year. Group 1 was given OMP + PUVA, group 2 OMP + UVB (NB, group 3 OMP + UVB (BB and group 4 was given OMP alone. Each patient was followed up for six months and then released from treatment. Clinical evaluation was made at the end of three and six months. Results: In group 1 (OMP + PUVA, marked improvement was seen in 18.51% while moderate improvement was seen in 66.66% of the patients. Marked improvement was seen in 37.03% in group 2 (OMP + NB-UVB while 44.44% had moderate improvement. In group 3 (OMP + BB UVB, 8.33% showed marked improvement while moderate improvement was seen in 25% of the patients. Marked and moderate improvement was seen in 5 and 10% of group 4 (OMP patients, respectively. Conclusions: Our study compared four treatment modalities in vitiligo patients, out of which oral minipulse of steroids (OMP only had an adjunct value and was not very effective by itself. Narrow band UVB has a definite edge over broad band UVB and should be preferred when both options are available. NB-UVB and PUVA showed comparable efficacy.

    The aim of the present study was to assess the diagnostic accuracy of 7 clinical tests for Morton's neuroma (MN) compared with ultrasonography (US). Forty patients (54 feet) were diagnosed with MN using predetermined clinical criteria. These patients were subsequently referred for US, which was performed by a single, experienced musculoskeletal radiologist. The clinical test results were compared against the US findings. MN was confirmed on US at the site of clinical diagnosis in 53 feet (98%). The operational characteristics of the clinical tests performed were as follows: thumb index finger squeeze (96% sensitivity, 96% accuracy), Mulder's click (61% sensitivity, 62% accuracy), foot squeeze (41% sensitivity, 41% accuracy), plantar percussion (37% sensitivity, 36% accuracy), dorsal percussion (33% sensitivity, 26% accuracy), and light touch and pin prick (26% sensitivity, 25% accuracy). No correlation was found between the size of MN on US and the positive clinical tests, except for Mulder's click. The size of MN was significantly larger in patients with a positive Mulder's click (10.9 versus 8.5 mm, p = .016). The clinical assessment was comparable to US in diagnosing MN. The thumb index finger squeeze test was the most sensitive screening test for the clinical diagnosis of MN. PMID:25432459

The World Bank and the European Bank for Reconstruction and Development published a series of reports on corporate governance. The present study uses data from these reports in order to illustrate how these developing economies are dealing with corporate governance. Based on ROSC Reports a corporate governance score was calculated. As this score shows, there is room for improvement for all three developing economies. This study is important because it shows the differences in corporate governance among developing economies and the need to study these nations at the individual country level. Corporate governance has many benefits for developing economies. It helps developing economies to register sustainable growth rates, to increases investors’ confidence in the national economy, and to increase the ability of capital markets to mobilize savings.

    Full Text Available Abstract Background Controversy exists regarding the optimal treatment for patients with displaced intracapsular fractures of the proximal femur. The recognised treatment alternatives are arthroplasty and internal fixation. The principal criticism of internal fixation is the high rate of non-union; up to 30% of patients will have a failure of the fixation leading to revision surgery. We believe that improved fracture healing may lead to a decreased rate of failure of fixation. We therefore propose to investigate strategies to both accelerate fracture healing and improve fixation that may significantly improve outcomes after internal fixation of intracapsular femoral fractures. We aim to test the clinical effectiveness of the osteoinductive agent platelet rich plasma and conduct a pilot study of a novel fixed-angle fixation system. Design We have planned a three arm, single centre, standard-of-care controlled, double blinded, pragmatic, randomised clinical trial. The trial will include a standard two-way comparison between platelet-rich plasma and standard-of-care fixation versus standard-of-care fixation alone. In addition there will be a subsidiary pilot arm testing a fixed-angle screw and plate fixation system. Trial Registration Current Controlled Trials ISRCTN49197425

    Full Text Available Background: Developmental dysplasia of hip (DDH is one of the congenital anomalies in newborns that if not diagnosed and treated on time can lead to a severe disability. Although clinical examination is a very useful way for screening, but in some patients, a confirmatory diagnostic method such as ultrasonography is needed. The aim of the present study is to compare the sensitivity and specificity of clinical examination and ultrasonography in early detecting of DDH. Materials and Methods: A total of 5800 of newborns were examined by orthopedic surgeon as a screening method. The newborns with risk factors or suspicious on clinical examination were introduced to repeat clinical and ultrasonographic examination of hip. The results were collected and recorded by a check list and then the sensitivity and specificity of clinical examination were calculated. Results: Of 5701 newborns (11402 hips who were studied by two methods of clinical examination and ultrasonography (by Graf method, the overall incidence of DDH was 29 per 1000. Only 94 hips (13.5% of 694 disordered ones according to clinical examination were involved on ultrasonographic evaluation. A total of 240 hips of 334 (72% involved hips according to ultrasonography (Graf type IIb or more were diagnosed normal on clinical examination, considering ultrasonography as a gold standard method of evaluating DDH, the sensitivity and specificity of clinical examination were calculated 28.1% and 94.5%, respectively. Conclusion: According to the present study, ultrasonogeraphic examination has a high valuable in screening of DDH and the clinical examination done by an experienced orthopedic surgeon has an acceptable value in primary screening of DDH in developing countries for detecting of healthy neonates, but if the newborn has a risk factor or is suspicious on clinical examination, it will be necessary to get assistance from ultrasonography by an experienced sonographer.

    Full Text Available Neurobiological mechanisms involved in sexual differentiation of the central nervous system will be presented with a comparative view across vertebrates. Women and men differ in a wide variety of behavioral traits and in the probabilities of developing certain mental disorders. A brief overview of sex-chromosome pathways underlying sexual dimorphisms will be provided. We will describe most common brain phenotypes derived in vivo with magnetic resonance imaging, discuss the challenges in interpreting these phenotypes vis-à-vis the underlying neurobiology and revise the known sex differences in brain structure from birth, through adolescence, to adulthood. Clinical and epidemiological data indicate important sex differences in the prevalence, course, and expression of psychopathologies such as schizophrenia, and mood disorders including major depression and bipolar illness. Recent evidence implies that mood disorders and psychosis share some common genetic predispositions, as well as some neurobiological basis. Therefore, modern research is emphasizing dimensional representation of mental disorders and conceptualization of schizophrenia, bipolar disorder and major depression as a continuum of cognitive deficits and neurobiological abnormalities. Herein, we have examined available evidence on cerebral sexual dimorphism in all three conditions to verify if sex differences vary quantitatively and/or qualitatively along the psychoses-depression continuum. Sex differences in posttraumatic disorders prevalence have also been described, thus data on differences at genomic and molecular levels will be considered. Finally, we will discuss the important contribution - advantages and limitations - of animal models in the investigation of underlying mechanisms of neurobehavioral sex differences in neuropsychiatric disorders, including drug dependence, with special emphasis in experimental models based on the neurodevelopmental and three hits hypotheses.

    The essential oil basil is obtained from the aerial parts of Ocimum basilicum L. After gas chromatographic separation, the following components were identified: linalol (54.95%), methylchavikol (11.98%), methylcinnamat (7.24%) and linolen (0.14%). The activity of basil against multidrug resistant clinical isolates from the genera Staphylococcus, Enterococcus and Pseudomonas has been studied. For this purpose, standard and modified broth macrodilution methods were used and time kill kinetic of basil was studied. The minimum inhibitory concentrations (MICs) were reported between 0.0030% and 0.0007% (v/v). These concentrations were compared with the inhibitory concentrations (ICs) and the logs of the bacterial counts reduction both obtained by basil diluted in 1% Tween (Tw) 80, saline test solution (STS) and spiritus vini (Sv) 95 degrees instead in a broth. The data, obtained after application of different methods of investigation and validated with membrane filtration, showed a strong inhibitory effect of basil on the test bacteria. The chosen bacteria are widespread and pose serious therapeutic difficulties because of their high level of resistance. For this reason, the results obtained were considered encouraging.

  4. Comparative study of bridge plate associated to the intramedullary pin and the dynamic compression plate on the experimental osteotomy fixation of femoral in rabbits (Oryctolagus cuniculus). Clinical, radiographic, histological and scintigraphy analyses

    International Nuclear Information System (INIS)

    The objectives were to benchmark and monitor the fracture healing of femoral osteotomy in rabbits after fixation with dynamic compression plate and bridge plate associated with intramedullary pin. Were used 14 New Zealand rabbits, four months old with mean weight of 3.5 pounds, from the Experimental Farm Professor Helio Barbosa of the Veterinary School of Minas Gerais Federal Univ. (UFMG). The animals were randomly divided into two groups (I and II). All rabbits underwent osteotomy across the middle third of right femur. In the group I was made to fix the osteotomy with the bridge plate (BP) associated with intramedullary pin, introduced the technique of minimal invasion. In group II, we used dynamic compression plate (DCP) via the conventional approach. Both groups were evaluated clinical, radiographic, histologic and scintigraphic findings. Clinical assessments were performed weekly until the 12th postoperative week and radiographic examinations were performed before, immediately after, at 15, 30, 45, 60 and 90 days. The bone scintigraphy were performed before and at 20, 50 and 90 days after surgery to monitor the bone metabolism qualitatively and quantitatively. Observed perfusion and bone healing process. After 90 days of study, there was histopathologic evaluation of the osteotomized area and the insertion of screws. In the region of the osteotomy was observed predominance of trabecular bone in group I and group II, the predominance of bone osteons, compatible with the original bone. On insertion of the screws did not differ between groups and there was cortical discontinuity, little necrosis and local hemorrhage. The two types of fixation have led to consolidation within the scheduled period, maturing in early fixation with DCP fixation compared with BP. Scintigraphy demonstrated by the indices of activity and image characteristics, the process of bone healing was significantly greater in animals undergoing early fixation with DCP. (author)

    Full Text Available INTRODUCTION : Percutaneous nephrolithotomy (PCNL is the most frequently performed surgery for stone disease at our institution. Nearly 100 PCNL procedures are being performed in a year at our institution. Septicemia following PCNL can be catastrophic despite sterile preoperative urine and prophylactic antibiotics. Infected stones, obstructed kidneys , and comorbidit y have been held responsible. In this study we analyzed various culture specimens, namely Mid - stream urine (MSU, renal pelvic urine and crushed stones. MATERIALS AND METHODS : We performed a prospective clinical study in all our patients undergoing PCNL b etween January 2013 and December 2014. MSU was sent for culture and sensitivity testing (C&S one day prior to surgery. Percutaneous access into the ipsilateral pelvicaliceal system is achieved under image intensification using a fine, 14 gauge Kellet need le. Urine from the pelvicaliceal system is first aspirated and sent as pelvic urine C&S. Stone fragments are collected to be proces0sed for C&S. The data collected were divided into 3 main groups, that is MSU C&S, pelvic urine C&S and stone C&S. RESULTS : A total of 83 patients were included in the study, of this MSU C&S was positive in 9/83 (10.8% patients, Pelvic C&S in 10 /73 (13.7% patients and Stone C&S in 25/83 (30.1% patients. Out of 25 cases of stone culture positive patients 17 patients develope d Systemic Inflammatory Response Syndrome (SIRS but only 2 patients developed SIRS in MSU C & S positive patients. CONCLUSIONS: The results of our study suggest that positive stone C&S is the better predictor of potential urosepsis than MSU. Stone cultur e is available only after surgery but appears to be the best guide for antibiotic therapy in case of sepsis. So the routine collection of stone for C&S will be beneficial

    Full Text Available Ketosis of lactating cows is among the most common metabolic diseases in modern dairy farms. The economic importance of the disease is caused by the reduced milk yield and body weight loss, poor feed conversion, lower conception rates, culling and increased mortality of affected animals. In the present study, a total of 47 high-yielding dairy cows up to 45 days in milk (DIM are included. All animals were submitted to physical examination wich included checking the rectal body temperature, heart rate, respiratory and rumen contraction rates, and inspection of visible mucous coats. The body condition was scored, and blood β-hydroxybutyrate (BHBA concentrations were assayed. The cows were divided into 3 groups: first group (control (n=24 with blood β-hydroxybutyrate level 2.6 mmol/l (clinical ketosis.

    Kawashima, Tomokazu

    2011-03-01

    Unlike autonomic nervous preservation in other surgeries for improving patient quality of life, autonomic cardiac nervous system (ACNS) preservation has been neglected in cardiovascular surgery because of technical difficulties and other unsolved issues. Because such ACNS preservation in cardiovascular surgery is anticipated in the future, detailed anatomical investigation of the human ACNS is required. Therefore, we have conducted morphological studies of the ACNS from macroscopic, clinical, and evolutionary anatomical viewpoints. In this study, I review detailed anatomical studies of the human ACNS together with their clinical implications. In addition, the evolutionary comparative anatomical significance of primate ACNS is also summarized to help understand and translate the findings of functional experiments to humans. These integrated findings will be the subject of a future study unifying molecular embryological and anatomical findings to clarify cardiac functions based on functional animal experiments, clinical applications such as improving surgery techniques and individual order-made surgery in cardiac surgery, and for future evaluation in regenerative medicine.

    The adverse effects and treatment failures to some of the currently recommended drugs for giardia infection have given rise to the need for alternative antigiardial agents. In an open, randomized parallel group study, the safety and efficacy of albendazole was compared with that of metronidazole for the treatment of giardiasis in children. Sixty two children aged between 2-12 years were randomized to receive either albendazole suspension 400 mg daily for 5 days or metronidazole suspension 7.5 mg/kg thrice daily for 5 days. The mean days required for cure, as evident by absence of cysts and/or trophozoites in the stool specimen, was 3.7 + 1.4 and 4.5 + 1.1 days, respectively for children on albendazole and metronidazole therapy. Six children on metronidazole therapy developed anorexia 2 to 4 days after the treatment. Albendazole proved as effective as metronidazole in the treatment of giardia infection in children with the added advantage of absence of anorexia. PMID:8613282

    Clinical diffusion imaging requires short acquisition times and good image quality to permit its use in various medical applications. In turn, these demands require the development of a robust and efficient post-processing framework in order to guarantee useful and reliable results. However, multiple artefacts abound in in vivo measurements; from either subject such as cardiac pulsation, bulk head motion, respiratory motion and involuntary tics and tremor, or imaging hardware related problems, such as table vibrations, etc. These artefacts can severely degrade the resulting images and render diffusion analysis difficult or impossible. In order to overcome these problems, we developed a robust and efficient framework enabling the use of initially corrupted images from a clinical study. At the heart of this framework is an improved least trimmed squares diffusion tensor estimation algorithm that works well with severely degraded datasets with low signal-to-noise ratio. This approach has been compared with other...

  15. Translating comparative effectiveness research into clinical practice: the UK experience.

    Science.gov (United States)

    Walley, Tom

    2012-01-22

    Comparative effectiveness research (CER) is not new but its potential to improve the effectiveness of healthcare has not yet been exploited in the US. Other countries such as the UK have more experience of this. Key points of the UK experience are summarized here and some possible pointers for the US are drawn. These include the following: how to go beyond the evidence and apply judgements to make recommendations with authority and in a timely manner; how to implement these recommendations; how to identify suitable topics; and how to be open and transparently fair to all stakeholders. The quality of the science of CER is key but this needs developing, and not just in biomedical or statistical terms but also in how to understand public expectations, and how to implement its recommendations. A key issue is the role of health economics, which seems to have been marginalized by the CER legislation, but perhaps this is more apparent than real. Clearly this is a matter for much further debate. It is hard to see how CER can deliver its potential without active consideration of both benefits and costs. Although other countries have more experience of this than does the US, the context for such work is always very specific and the US will have to find its own way, while trying to avoid some of the errors made elsewhere.

    The objective of the study was to undertake evidence-base study to evaluate clinical manifestation of the over-estimated use of herbal drug Plantago ovata and to compare it with placebo for the efficacy and adverse effects. The patients of both genders were included. Blood urea, creatinine, ALT, Serum B12, CP, ESR and liver function tests were performed. The data was statistically analyzed in both groups for differential symptomatology. In anorexia test verses control results showed that Plantago ovata husk and placebo showed the affected ratio as 81 percent and 50 percent, correspondingly. Whereas in clinical performance of heart burning, pain in epigastrium, low libido, body pain, dyspepsia, fever, burning sensation in palm and sole in test drug showed affected response as adverse effect 90%, 88% and as control drug, 36%, 29%, 22%, 25%, 38%, 30%, 33%, 57%, respectively. The results were highly marked in test drug i.e. in comparison with placebo. This is clearly evident from data analysis that effect observed in test arm is far more superior hence null hypothesis was rejected clearly. Similarly serological and biochemical reports study i.e. (ALT, Vit. B1 and Vit A) revealed that there is no hepatotoxic and neurotoxic effect found in both the drugs. PMID:27087080

    2008-01-01

    Second-generation histamine H(1) receptor antagonists were developed to provide efficacious treatment of allergic rhinitis (AR) and chronic idiopathic urticaria (CIU) while decreasing adverse effects associated with first-generation agents. When comparing the efficacy and safety profiles of the newest second-generation antihistamines - desloratadine, fexofenadine and levocetirizine - many pharmacological and clinical criteria must be considered. Most importantly, these elements should not be evaluated separately but, rather, as parts of a puzzle that create a whole picture. As a class, second-generation antihistamines are highly selective for the H(1) receptor. Some bind to it with high affinity, although there is marked heterogeneity among the various compounds. They have a limited effect on the CNS, and clinical studies have noted almost no significant drug-drug interactions in the agents studied. No major cytochrome P450 inhibition has been reported with desloratadine, fexofenadine and levocetirizine, and the bioavailability of desloratadine is minimally affected by drugs interfering with transporter molecules. Of the second-generation antihistamines, desloratadine has the greatest binding affinity for the H(1) receptor. The use of desloratadine, fexofenadine and levocetirizine is not associated with clinically relevant antimuscarinic effects. Desloratadine and fexofenadine do not impair cognitive or psychomotor functioning and are comparable with placebo in terms of somnolence. Based on these pharmacological characteristics, as well as clinical endpoints such as symptom scores, quality-of-life surveys, inflammatory cell counts and investigators' global evaluations, we conclude that desloratadine, fexofenadine and levocetirizine are all efficacious treatments for AR and CIU. However, differences among the antihistamines in relation to a lack of significant interaction with drug transporter molecules and somnolence in excess of placebo may provide some advantages

    Clinical experiences are recognized as a critical aspect of nursing education, highlighting the importance of the perspectives of those providing clinical instruction. The aim of this mixed methods descriptive study was to discover the knowledge and guidance needs of preceptors and clinical faculty who provide clinical instruction to Bachelor of Science in Nursing (BSN) students. Fifteen clinical faculty and 17 preceptors were surveyed using a questionnaire developed and piloted by the researchers. Although preceptors and clinical faculty reported a high level of knowledge and confidence in their ability to guide student nurses, they also identified the need for additional support for their teaching roles. Analysis of the qualitative data provided insights into what helped and what hindered clinical instruction, as well as what could enhance clinical instruction. The development, implementation, and evaluation of formal education and mentorship processes for preceptors and clinical faculty are recommended in order to meet these knowledge and guidance gaps. Further research is also needed to explore how to clinical instruction could be tailored to the capacity of those engaged in the experiences and to clinical environments. PMID:26775165

  5. Efficacy of panoramic radiography as a screening procedure in dental examination compared with clinical evaluation

    International Nuclear Information System (INIS)

    To evaluate the efficacy of panoramic radiography by comparing the results of clinical examination with radiographic findings. We studied 190 patients (20 men and 170 women; mean age, 40 years; range, 22 to 68 years) who visited the health promotion center of Korea Medical Science Institute and were examined both clinically and by panoramic radiography. We compared results from both examinations. Treatment options by clinical examination were described as 'no treatment indicated', 'treatment of dental caries', 'removal of calculus', 'treatment of periodontal disease'. 'prothodonic treatment' and 'extraction of the third molar'. Findings taken from the panoramic radiography were: dental caries, peroapical lesion, alveolar bone loss, calculus deposition, retained root, impaction of the third molar, disease of maxillary sinus, bony change of mandibular condyle, etc. The prevalence of panoramic findings were: 37.9% of dental caries, 17.4% of periapical lesions, 44.7% of alveolar bone losses, 62.6% of calculi deposition. 7.9% of retained roots, 26.8% of third molar impactions, 6.3% of disease of maxillary sinus, 2.1% of bony changes of mandibular condlye and 35.8% of miscellaneous lesions. Abnormal conditions revealed by panoramic radiography which had not been discovered on clinical examination were: 24.2% of the patients had dental caries, 17.4% had periapical lesions, 7.4% had calculi deposition, 5.3% had retained roots, 15.3% had third molar impactions. The opposite cases were: 5.2% had dental caries, 12.6% had calculi deposition, and 9.5% had third molar impactions. The use of panoramic radiography as a supplement to the clinical examination might be a valuable screening technique

    Coronary heart disease (CHD) represents a major global health burden. However, despite the well-known influence that dietary habits exert over the progression of this disease, there are no well-established and scientifically sound dietary approaches to prevent the onset of clinical outcomes in secondary prevention. The objective of the CORonary Diet Intervention with Olive oil and cardiovascular PREVention study (CORDIOPREV study, clinical trials number NCT00924937) is to compare the ability of a Mediterranean diet rich in virgin olive oil versus a low-fat diet to influence the composite incidence of cardiovascular events after 7 years in subjects with documented CHD at baseline. For this purpose, we enrolled 1,002 coronary patients from Spain. Baseline assessment (2009-2012) included detailed interviews and measurements to assess dietary, social, and biological variables. Results of baseline characteristics: The CORDIOPREV study in Spain describes a population with a high body mass index (37.2% overweight and 56.3% obesity) and with a median of low-density lipoprotein cholesterol of 88.5 mg/dL (70.6% of the patients having study, which will test for the first time the efficacy of a Mediterranean diet rich in extra virgin olive oil as compared with a low-fat diet on the incidence of CHD recurrence in a long-term follow-up study.

    International Nuclear Information System (INIS)

    For the purpose of comparing the merits and demerits of various advanced fuel cycles, parametric studies of operation conditions are examined. The effects of nuclear elastic collisions and synchrotron radiation are taken into account. It is found that the high-#betta# Catalyzed DD fuel cycle with the transmutation of fusion-produced tritium into helium-3 is most feasible from the point of view of neutron production and tritium handling. The D-D fuel cycles seem to be less attractive compared to the Catalyzed DD. The p-11B and p-6Li fusion plasmas hardly attain the plasma Q value relevant to reactors. (author)

However, conducting a highly ranked in the evidence hierarchy pyramid is not easy or feasible at all times and places. There remains a room for descriptive clinical outcome measure studies with admitting the limit of the intepretation. Aims: Presents three Korean clinic based outcome measure studies with a view to encouraging Korean clinicians to conduct similar studies. Methods: Three studies are presented briefly here including 1 Quality of Life of liver cancer patients after 8 Constitutional acupuncture; 2 Developing a Korean version of Measuring yourself Medical Outcome profile (MYMOP; and 3 Survey on 5 Shu points: a pilot In the first study, we have included 4 primary or secondary liver cancer patients collecting their diagnostic X-ray film and clinical data f개m their hospital, and asked them to fill in the European Organization Research and Treatment of Cancer, Quality of Life Questionnaire before the commencement of the treatment. The acupuncture treatment is set up format but not disclosed yet. The translation and developing a Korean version of outcome measures that is Korean clinician friendly has been sought for MYMOP is one of the most appropriate one. The permission was granted, the translation into Korean was done, then back translated into English only based on the Korean translation by the researcher who is bilingual in both languages. The back translation was compared by the original developer of MYMOP and confirmed usable. In order to test the existence of acupoints and meridians through popular forms of Korean acupuncture regimes, we aim at collecting opinions from 101 Korean clinicians that have used those forms. The questions asked include most effective symptoms, 5 Shu points, points those are least likely to use due to either adverse events or the lack of effectiveness, theoretical reasons for the above proposals, proposing outcome measures

    Full Text Available Etanercept is a recombinant fusion protein approved for the treatment of TNF-α mediated diseases such as rheumatoid arthritis (RA, psoriasis, psoriatic arthritis, and ankylosing spondylitis. Herein, we present an evaluation of the physicochemical and biological properties of a biosimilar etanercept and its reference product followed by a clinical study in patients diagnosed with RA intended to demonstrate comparability of their immunomodulatory activity. Identity analyses showed a total correspondence of the primary and higher-order structure between the two products. In regard to intrinsic heterogeneity, both products showed to be highly heterogenous; however the biosimilar etanercept exhibited similar charge and glycan heterogeneity intervals compared to the reference product. Apoptosis inhibition assay also showed that, despite the high degree of heterogeneity exhibited by both products, no significant differences exist in their in vitro activity. Finally, the clinical assessment conducted in RA-diagnosed patients did not show significant differences in the evaluated pharmacodynamic markers of both products. Collectively, the results from the comparability exercise provide convincing evidence that the evaluated biosimilar etanercept can be considered an effective alternative for the treatment of RA.

    Full Text Available BACKGROUND The duodenal injury can pose a formidable challenge to the surgeon and failure to manage it properly may have devastating results. Over the centuries, there was little to offer the patient of acute abdomen beyond cupping, purgation and enemas, all of which did more harm than good. It was not until 1884 that Mikulicz made an attempt to repair a perforation. Recent statistics indicate roughly 10% of population develop gastric or duodenal ulcer in life time. Roughly 1-3% of population above the age of 20 years have some degree of peptic ulcer activity during any annual period. A detailed history with regards to the signs and symptoms of the patient, a meticulous examination, radiological and biochemical investigations help to arrive at a correct preoperative diagnosis. In this study, a sincere effort has been put to understand the demographic patterns, to understand the underlying aetiology and to understand the effectiveness of the standard methods of investigation and treatment in use today. METHODS This is a 24 months prospective study i.e., from September 2011 to September 2013 carried out at Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation. The study included the patients presenting to Dr. Pinnamaneni Siddhartha Institute of Medical Sciences & Research Foundation to emergency ward with signs and symptoms of hollow viscus perforation. The sample size included 30 cases of duodenal perforation. RESULTS Duodenal ulcer perforation commonly occurs in the age group of 30-60 years, but it can occur in any age group. Majority of the patients were male. Smoking and alcohol consumption were risk factors in most cases (53.3% for the causation of duodenal ulcer perforation. Sudden onset of abdominal pain, situated at epigastrium and right hypochondrium was a constant symptom (100%. Vomiting, constipation and fever were not so common. CONCLUSION The emergency surgical management for perforated duodenal ulcer is by

  13. Cross-sectional analysis of data from the U.S. clinical trials database reveals poor translational clinical trial effort for traumatic brain injury, compared with stroke.

    Directory of Open Access Journals (Sweden)

    Lucia M Li

    Full Text Available Traumatic brain injury (TBI is an important public health problem, comparable to stroke in incidence and prevalence. Few interventions have proven efficacy in TBI, and clinical trials are, therefore, necessary to advance management in TBI. We describe the current clinical trial landscape in traumatic brain injury and compare it with the trial efforts for stroke. For this, we analysed all stroke and TBI studies registered on the US Clinical Trials (www.clinicaltrials.gov database over a 10-year period (01/01/2000 to 01/31/2013. This methodology has been previously used to analyse clinical trial efforts in other specialties. We describe the research profile in each area: total number of studies, total number of participants and change in number of research studies over time. We also analysed key study characteristics, such as enrolment number and scope of recruitment. We found a mismatch between relative public health burden and relative research effort in each disease. Despite TBI having comparable prevalence and higher incidence than stroke, it has around one fifth of the number of clinical trials and participant recruitment. Both stroke and TBI have experienced an increase in the number of studies over the examined time period, but the rate of growth for TBI is one third that for stroke. Small-scale (<1000 participants per trial and single centre studies form the majority of clinical trials in both stroke and TBI, with TBI having significantly fewer studies with international recruitment. We discuss the consequences of these findings and how the situation might be improved. A sustained research effort, entailing increased international collaboration and rethinking the methodology of running clinical trials, is required in order to improve outcomes after traumatic brain injury.

  14. Comparative X-ray investigation of lateral and anterior-posterior ankle-joint images - comparison with pathological and anatomical findings concerning lateral ankle-joint lesions and their clinical importance, studied in a special type of holding device

    International Nuclear Information System (INIS)

    The study reports on a possibility to interpret the relation of the different bone structures of the upper ankle-joint to one another in the X-ray picture without using contrast media. Modern funtional diagnostic methods increasingly make use of X-ray pictures taken in fixed position. It seems useful to standardize such X-ray images of the ankle-joint in order to make them reproducible. The author developed a device that would suit these purposes. A diagnosis required the reproduction of the accidental mechanism. The clinical symptoms do not permit to clearly state the extent of the lesion of the ligaments. The results of the post-operative follow-up examinations confirm the urgent necessity of the standardized diagnostic method presented and the success of the therapy applied. The presented X-ray method permits safe diagnosis of ruptures of the ligaments. Location of a certain rupture is not possible with the fixed-position X-ray screening. For a clear assessment of lesions of the ligaments at the lateral ankle-joint, X-ray pictures must be taken both in the anterior-posterior path of rays and in the lateral one. A normal result in the lateral path of rays does not exclude a pathologic result in the anterior-posterior path of rays, and vice versa. (orig./MG)

    International Nuclear Information System (INIS)

    We conducted prospective study comparing different methods (plain X-rays, computed tomography and ultrasonography mode-A) for the initial diagnosis of maxillary sinusitis. Twenty patients (40 maxillary sinuses) with a clinical history suggestive of sinusitis included in this study. The results were classified as abnormal or normal, using computed tomography as gold standard. The sensitivity for ultrasonography and plain X-rays was 84.6% and 69.2%, respectively. The specificity of both methods was 92.6%. This study suggests that ultrasonography can be used as a good follow-up method for patients with maxillary. sinusitis. (author)

Lipid profile did not change significantly in group 1 while patients in group 2 showed a significant decrease in lipid levels. The positive dynamics of neuro- logical status was observed in both groups, however, the most significant - in group 2. Reduction in a number of endothelial desquamated cells was 45.7% in group 2 and 13.3% in group 1 (p=0.00001. GFR increased significantly in patients of group 2.Conclusion. The long-term treatment with simvastatin in combination with neuroprotective and antihypertensive therapy in patients with acute ischemic stroke leads to decrease in the incidence rate of clinically relevant events, improvement of endothelial function, neurological status and prognosis.

    Ovarian adult-type granulosa cell tumors (AGCTs) require prolonged follow-up, but evidence regarding the optimal follow-up marker is lacking. The objective of our study was to validate the clinical usefulness of serum anti-Müllerian hormone (AMH) and the current marker inhibin B as single and combined markers of AGCTs. We conducted a longitudinal, partially prospective cohort study of 123 premenopausal and postmenopausal AGCT patients with a median follow-up time of 10.5 years (range 0.3-50.0 years). Serum AMH and inhibin B levels were measured from 560 pretreatment and follow-up serum samples by using immunoenzymometric assays. We found that serum AMH and inhibin B levels were significantly elevated in patients with primary or recurrent AGCTs. The levels of both markers positively correlated to tumor size (p < 0.05). AMH and inhibin B performed similarly in receiving operator characteristic analyses; area under the curve (AUC) values were 0.92 [95% confidence interval (CI) 0.88-0.95] for AMH, and 0.94 (95% CI 0.90-0.96) for inhibin B. AMH was highly sensitive (92%) and specific (81%) in detecting a macroscopic AGCT. However, in AUC comparison analyses, the combination of the markers was superior to inhibin B alone. In conclusion, serum AMH is a sensitive and specific marker of AGCT, and either AMH or inhibin B can be monitored during follow-up. However, combining AMH and inhibin B in AGCT patient follow-up improves the detection of recurrent disease. PMID:25808251

  18. Comparative Studies on Retroviral Proteases: Substrate Specificity

    Full Text Available Exogenous retroviruses are subclassified into seven genera and include viruses that cause diseases in humans. The viral Gag and Gag-Pro-Pol polyproteins are processed by the retroviral protease in the last stage of replication and inhibitors of the HIV-1 protease are widely used in AIDS therapy. Resistant mutations occur in response to the drug therapy introducing residues that are frequently found in the equivalent position of other retroviral proteases. Therefore, besides helping to understand the general and specific features of these enzymes, comparative studies of retroviral proteases may help to understand the mutational capacity of the HIV-1 protease.

  19. EFQPSK Versus CERN: A Comparative Study

    2001-01-01

    This report presents a comparative study on Enhanced Feher's Quadrature Phase Shift Keying (EFQPSK) and Constrained Envelope Root Nyquist (CERN) techniques. These two techniques have been developed in recent times to provide high spectral and power efficiencies under nonlinear amplifier environment. The purpose of this study is to gain insights into these techniques and to help system planners and designers with an appropriate set of guidelines for using these techniques. The comparative study presented in this report relies on effective simulation models and procedures. Therefore, a significant part of this report is devoted to understanding the mathematical and simulation models of the techniques and their set-up procedures. In particular, mathematical models of EFQPSK and CERN, effects of the sampling rate in discrete time signal representation, and modeling of nonlinear amplifiers and predistorters have been considered in detail. The results of this study show that both EFQPSK and CERN signals provide spectrally efficient communications compared to filtered conventional linear modulation techniques when a nonlinear power amplifier is used. However, there are important differences. The spectral efficiency of CERN signals, with a small amount of input backoff, is significantly better than that of EFQPSK signals if the nonlinear amplifier is an ideal clipper. However, to achieve such spectral efficiencies with a practical nonlinear amplifier, CERN processing requires a predistorter which effectively translates the amplifier's characteristics close to those of an ideal clipper. Thus, the spectral performance of CERN signals strongly depends on the predistorter. EFQPSK signals, on the other hand, do not need such predistorters since their spectra are almost unaffected by the nonlinear amplifier, Ibis report discusses several receiver structures for EFQPSK signals. It is observed that optimal receiver structures can be realized for both coded and uncoded EFQPSK

    There has been a significant amount of research in the area of building energy efficiency and durability. However, well-documented quantitative information on the impact of crawlspaces on the performance of residential structures is lacking. The objective of this study was to evaluate and compare the effects of two crawlspace strategies on the whole-house performance of a pair of houses in a mixed humid climate. These houses were built with advanced envelope systems to provide energy savings of 50% or more compared to traditional 2010 new construction. One crawlspace contains insulated walls and is sealed and semi-conditioned. The other is a traditional vented crawlspace with insulation in the crawlspace ceiling. The vented (traditional) crawlspace contains fiberglass batts installed in the floor chase cavities above the crawl, while the sealed and insulated crawlspace contains foil-faced polyisocyanurate foam insulation on the interior side of the masonry walls. Various sensors to measure temperatures, heat flux through crawlspace walls and ceiling, and relative humidity were installed in the two crawlspaces. Data from these sensors have been analyzed to compare the performance of the two crawlspace designs. The analysis results indicated that the sealed and insulated crawlspace design is better than the traditional vented crawlspace in the mixed humid climate.

  1. A Comparative Study of Mammalian Diversification Pattern

    Full Text Available Although mammals have long been regarded as a successful radiation, the diversification pattern among the clades is still poorly known. Higher-level phylogenies are conflicting and comprehensive comparative analyses are still lacking. Using a recently published supermatrix encompassing nearly all extant mammalian families and a novel comparative likelihood approach (MEDUSA, the diversification pattern of mammalian groups was examined. Both order- and family-level phylogenetic analyses revealed the rapid radiation of Boreoeutheria and Euaustralidelphia in the early mammalian history. The observation of a diversification burst within Boreoeutheria at approximately 100 My supports the Long Fuse model in elucidating placental diversification progress, and the rapid radiation of Euaustralidelphia suggests an important role of biogeographic dispersal events in triggering early Australian marsupial rapid radiation. Diversification analyses based on family-level diversity tree revealed seven additional clades with exceptional diversification rate shifts, six of which represent accelerations in net diversification rate as compared to the background pattern. The shifts gave origin to the clades Muridae+Cricetidae, Bovidae+Moschidae+Cervidae, Simiiformes, Echimyidae, Odontoceti (excluding Physeteridae+Kogiidae+Platanistidae, Macropodidae, and Vespertilionidae. Moderate to high extinction rates from background and boreoeutherian diversification patterns indicate the important role of turnovers in shaping the heterogeneous taxonomic richness observed among extant mammalian groups. Furthermore, the present results emphasize the key role of extinction on erasing unusual diversification signals, and suggest that further studies are needed to clarify the historical radiation of some mammalian groups for which MEDUSA did not detect exceptional diversification rates.

    Novel approaches to observational studies and clinical trials could improve the cost-effectiveness and speed of translation of research. Hybrid designs that combine elements of clinical trials with observational registries or cohort studies should be considered as part of a long-term strategy to transform clinical trials and epidemiology, adapting to the opportunities of big data and the challenges of constrained budgets. Important considerations include study aims, timing, breadth and depth of the existing infrastructure that can be leveraged, participant burden, likely participation rate and available sample size in the cohort, required sample size for the trial, and investigator expertise. Community engagement and stakeholder (including study participants) support are essential for these efforts to succeed. PMID:26611435

    Processes involving the sublimation of volatiles dominate cometary activity and drive the release of ancient material from within the nucleus into the coma. As comets are kept cold for most of their history, they contain the least processed primordial materials that accumulated into the giant planets. In addition, comets may have delivered their ices and organics to the primitive Earth. The Deep Impact eXtended Investigation (DIXI) to comet Hartley 2 revealed a highly active comet with bright icy-rich jets. We present a detailed characterization of the composition and texture of the ices and refractories in the inner-most coma of Hartley 2, closer than a few kilometers from the surface. This analysis is conducted using laboratory measurements of optical constants of cometary analog materials. We also discuss the implications of these findings on the accretion process that led to the formation of cometary nuclei and therefore of planets. The physical makeup of the ice grains in comet Hartley 2 is compared with that of water ice in the interior, surface, and coma of other comets (e.g., 9P/Tempel 1, C/2002 T7 (LINEAR), 17P/Holmes). Through this comparative study, we investigate how ice is redistributed from the interior to the surface and ultimately into the coma of comets.

    Background Apolipoprotein (Apo) B-48 is an intestinally derived lipoprotein that is expected to be a marker for cardiovascular disease (CVD). Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a vascular-specific inflammatory marker and important risk predictor of CVD. The aim of this study was to explore the effect of pitavastatin treatment and life style modification (LSM) on ApoB-48 and Lp-PLA2 levels in metabolic syndrome (MS) patients at relatively low risk for CVD, as a sub-analysis of a previous multi-center prospective study. Methods We enrolled 75 patients with MS from the PROPIT study and randomized them into two treatment groups: 2 mg pitavastatin daily+intensive LSM or intensive LSM only. We measured the change of lipid profiles, ApoB-48 and Lp-PLA2 for 48 weeks. Results Total cholesterol, low density lipoprotein cholesterol, non-high density lipoprotein cholesterol, and ApoB-100/A1 ratio were significantly improved in the pitavastatin+LSM group compared to the LSM only group (P≤0.001). Pitavastatin+LSM did not change the level of ApoB-48 in subjects overall, but the level of ApoB-48 was significantly lower in the higher mean baseline value group of ApoB-48. The change in Lp-PLA2 was not significant after intervention in either group after treatment with pitavastatin for 1 year. Conclusion Pitavastatin treatment and LSM significantly improved lipid profiles, ApoB-100/A1 ratio, and reduced ApoB-48 levels in the higher mean baseline value group of ApoB-48, but did not significantly alter the Lp-PLA2 levels.

    Airfoil flow separation impacts a multitude of applications including turbomachinery, wind turbines, and bio-inspired micro-aerial vehicles. In order to achieve maximum performance, some devices operate near the edge of flow separation, and others use dynamic flow separation advantageously. Numerous criteria exist for predicting the onset of airfoil flow separation. This talk presents a comparative study of a number of such criteria, with emphasis paid to speed and accuracy of the calculations. We evaluate the criteria using a two-dimensional unsteady vortex lattice method, which allows for rapid analysis (on the order of seconds instead of days for a full Navier-Stokes solution) and design of optimal airfoil geometry and kinematics. Furthermore, dynamic analyses permit evaluation of dynamic stall conditions for enhanced lift via leading edge vortex shedding, commonly present in small flapping-wing flyers such as the bumblebee and hummingbird.

    A fine structure of bacteria flagella is an important problem of molecular cell biology. Bacteria flagella are the self-assembled structures that allow to use the flagellum protein in a number of biotechnological applications. However, at present, there is a little information about high resolution scanning probe microscopy study of flagellum structure, in particular, about investigation of Vibrio cholerae flagella. In our lab have been carried out the high resolution comparative investigation of V. cholerae flagella by means of various microscopes: tunneling (STM), scanning force (SFM) and electron transmission. As a scanning probe microscope is used designed in our lab versatile SPM with replaceable measuring heads. Bacteria were grown, fixed and treated according to the conventional techniques. For STM investigations samples were covered with Pt/Ir thin films by rotated vacuum evaporation, in SFM investigations were used uncovered samples. Electron microscopy of the negatively stained bacteria was used as a test procedure.

  18. Alternative waste forms: a comparative study

    International Nuclear Information System (INIS)

    A characterization study utilizing comparative tests has been conducted to assess product inertness of alternative waste form materials, having evaluated at this point four basic product types: sintered ceramics, glass ceramics, glass and concrete. The seven specific waste form materials studied represent simulated nuclear waste loading of 5% to 100%, processed between room temperature and 12000C and subjected to characterization tests including phase analysis, microstructure, compression testing, volatility and leach testing. Significant conclusions based upon the results obtained to date are: sintered calcine waste form PW-9 does not retain Na, Mo and Cs when leached 900C and, in fact, does not remain a solid; glass and supercalcine are alike under both hydrous and hydrothermal leach conditions with glass exhibiting a greater retention of sodium and molybdenum, supercalcine having a greater retention of cesium, and both forms approximately equal in strontium retention; volatility measurements indicate that an order of magnitude decrease in volatility occurs when a calcine waste form is incorporated in a crystalline or glassy host; glass 76-68 is superior to supercalcine SPC-5B in retention of volatiles below 11000C because of the high release of Na from SPC-5B, however, as the temperature approaches or exceeds the glass melt temperature, volatile losses of the glass equal or exceed that of SPC-5B; glass 76-68 and supercalcine SPC-5B have high compressive strengths when compared to sintered PW-9 and cement products. This is apparently due to a stronger continuum bond resulting from a glassy matrix or crystalline ingrowth over a simple mechanical agglomeration of particles

    Full Text Available Background: To compare and evaluate the intra- and inter-examiner efficacy and reproducibility of the first-generation manual (Williams probe and the third-generation Florida probe in terms of measuring pocket probing depth (PD and clinical attachment level (CAL. Materials and Methods: Forty subjects/4000 sites were included in this comparative, cross-sectional study. Group- and site-wise categorizations were done. Based on gingival index, PD, and CAL, patients were divided into four groups, i.e., periodontally healthy, gingivitis, mild to moderate periodontitis, and severe periodontitis. Further, based on these parameters, a total of 4000 sites, with 1000 sites in each category randomly selected from these 40 patients, were taken. Full mouth PD and CAL measurements were recorded with two probes, by Examiner 1 and on Ramfjord teeth by Examiner 2. Results: Full mouth and Ramfjord teeth group- and site-wise PD obtained with the manual probe by both the examiners were statistically significantly deeper than that obtained with the Florida probe. The full mouth and Ramfjord teeth mean CAL measurement by Florida probe was higher as compared to manual probe in mild to moderate periodontitis group and sites, whereas in severe periodontitis group and sites, manual probe recorded higher CAL as compared to Florida probe. Conclusion: Mean PD and CAL measurements were deeper with the manual probe as compared to the Florida probe in all the groups and sites, except for the mild-moderate periodontitis group and sites where the CAL measurements with the manual probe were less than the Florida probe. Manual probe was more reproducible and showed less interexaminer variability as compared to the Florida probe.

    A comparative study of the contact angles of air bubbles, hydrocarbon oils (benzene and dodecane - both in the absence and in the presence of water-soluble dodecylamine (laurylamine) chloride), flocculants and coagulants drops on flat polished coal surfaces immersed in water was made. The effect of the hydrocarbon chain length of some n-alkylamine chlorides on the coal-oil-water was also investigated. The relationship of the measured contact angles to the flocculants, coagulants and dodecylamide chloride concentrations and pH was established. Results obtained show that maximum contact angles for the coals studied occur in the alkaline pH range (pH > 7) for the systems investigated. Evidence is also provided to show that benzene and dodecane do not spread spontaneously on wet coal surfaces, even in the presence of a water-soluble cationic surfactant. The results further show that the coal-benzene water contact angles increase with an increase in the hydrocarbon chain length of the surfactant. Coagulants probably affect flotation of coal fines adversely, whereas flocculants have a remarkable effect on contact angles similar to that of surfactants.

  4. Treatment of helicobacter pylori infection; a controlled randomized comparative clinical trial

    International Nuclear Information System (INIS)

    Helicobacter pylori induces chronic inflammation of the underlying gastric mucosa and is strongly linked to the development of duodenal and gastric carcinoma. A study was conducted to evaluate the efficacy of Pylorex, a herbal formulation, for treatment of H. pylori infection as compared to triple allopathic therapy (Omeprazole, Amoxicillin, Metronidazole). The therapeutic evaluations of these medicines were conducted on 97 clinically and immunologically diagnosed cases of H. pylori infection. H. pylori was eradicated in 16 (32.6%) out of 49 patients by the use of triple allopathic therapy (Control drugs), and in 9 (18.7%) out of 48 patients by the use of Pylorex (Test drug). Pylorex possesses a therapeutic value for the treatment of H. pylori associated symptoms but the eradication rate is superior in triple allopathic therapy. (author)

    Full Text Available Abstract Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

    Highlights: {yields} VEGF is a mediator of angiogenesis. {yields} VEGF inhibitors have clinical applications in cancer and eye disorders. {yields} Five protein VEGF inhibitors were compared for their ability to inhibit. {yields} VEGF-induced activities in cultured endothelial cells. -- Abstract: VEGF inhibitors are widely used as a therapy for tumors and intravascular neovascular disorders, but limited and conflicting data regarding their relative biological potencies are available. The purpose of the study is to compare different protein VEGF inhibitors for their ability to inhibit VEGF-stimulated activities. We tested ranibizumab, the full-length variant of ranibizumab (Mab Y0317), bevacizumab, the VEGF-TrapR1R2 and Flt(1-3)-IgG in bioassays measuring VEGF-stimulated proliferation of bovine retinal microvascular endothelial cells or chemotaxis of human umbilical vein endothelial cells (HUVEC). The inhibitors were also compared for their ability to inhibit MAP kinase activation in HUVECs following VEGF addition. Ranibizumab, VEGF-TrapR1R2 and Flt(1-3)-IgG had very similar potencies in the bioassays tested. Bevacizumab was over 10-fold less potent than these molecules. Mab Y0317 was over 30-fold more potent than bevacizumab. The findings reported in this manuscript describe important intrinsic characteristics of several VEGF inhibitors that may be useful to design and interpret preclinical or clinical studies.

    The objective of this study was to compare ceftiofur hydrochloride with a positive control protocol for intramammary treatment of nonsevere clinical mastitis in dairy cows. A total of 264 clinical mastitis cases on 11 commercial dairy farms were treated with intramammary infusions, once a day for 4 d using 1 of 2 treatments: (1) ceftiofur hydrochloride 125mg; or (2) control: tetracycline 200mg + neomycin 250mg + bacitracin 28mg + prednisolone 10mg. Streptococcus agalactiae was the most frequently isolated gram-positive pathogen from clinical mastitis, followed by Staphylococcus aureus. Klebsiella spp. and Escherichia coli were the most isolated gram-negative bacteria from clinical mastitis. No significant differences were observed between treatments regarding the overall clinical cure, bacteriological cure, and new infection. No effect of treatment regimen was observed when the bacterial group (gram-positive vs. gram-negative) was evaluated. The overall clinical cure was 0.79 for ceftiofur-treated cows and 0.74 for control-treated cows, whereas the overall bacteriological cure was 0.79 for ceftiofur-treated cows and 0.76 for control-treated cows. Furthermore, the new intramammary infection was 0.10 for cows treated with ceftiofur and 0.11 for cows treated with control. In conclusion, the use of intramammary ceftiofur hydrochloride for treatment of nonsevere clinical mastitis has similar efficacy as a treatment regimen with a combination of antimicrobial agents (tetracycline + neomycin + bacitracin).

    The goal of this prospective randomized clinical trial was to compare 2 cohorts of standardized cleft patients with regard to functional speech outcome and the presence or absence of palatal fistulae. The 2 cohorts are randomized to undergo either a conventional von Langenbeck repair with intravelar velarplasty or the double-opposing Z-plasty Furlow procedure. A prospective 2 × 2 × 2 factorial clinical trial was used in which each subject was randomly assigned to 1 of 8 different groups: 1 of 2 different lip repairs (Spina vs. Millard), 1 of 2 different palatal repair (von Langenbeck vs. Furlow), and 1 of 2 different ages at time of palatal surgery (9-12 months vs. 15-18 months). All surgeries were performed by the same 4 surgeons. A cul-de-sac test of hypernasality and a mirror test of nasal air emission were selected as primary outcome measures for velopharyngeal function. Both a surgeon and speech pathologist examined patients for the presence of palatal fistulae. In this study, the Furlow double-opposing Z-palatoplasty resulted in significantly better velopharyngeal function for speech than the von Langenbeck procedure as determined by the perceptual cul-de-sac test of hypernasality. Fistula occurrence was significantly higher for the Furlow procedure than for the von Langenbeck. Fistulas were more likely to occur in patients with wider clefts and when relaxing incisions were not used. PMID:21042188

    Cranio-maxillofacial malformations, as seen in Crouzon and Apert syndromes, may impose an immense distress on both function and aesthetics of the person affected. The aims of this study were to describe and compare the main facial and intraoral features of patients with Apert and Crouzon syndromes, the clinical manifestations that may be present, additionally to the main syndromic traits, as well as the cranio-maxillofacial surgical treatment protocols followed.Twenty-three patients with Apert syndrome (6 males, 17 females), and 28 patients with Crouzon syndrome (20 males, 8 females) were evaluated for general medical aspects, craniofacial characteristics, dentoalveolar traits before and after the final orthognathic surgery, and types and timing of cranio-maxillofacial operations. Mental retardation, associated additional malformations, cleft palate, and extensive lateral palatal soft tissue swellings were more common in children with Apert syndrome. In both syndromes, clinical findings included concave profile, negative overjet, posterior crossbites, anterior openbite, and dental midline deviation, which were corrected in almost all cases with the final orthognathic surgery, with the exception of the lateral crossbites, including more than one tooth pair, which were persisting in about half of the cases. Cranial vault decompression and/or reshaping, midfacial and orbital advancement procedures, often in conjunction with a mandibular setback, were the most frequent cranio-maxillofacial operations performed. In conclusion, Apert syndrome is more asymmetric in nature and a more severe clinical entity than Crouzon syndrome. The syndromic dentofacial features of both conditions could be significantly improved after a series of surgical procedures in almost all cases with the exception of the posterior crossbites, with haIf of them persisting post-surgically.

  12. COMPARATIVE STUDY ON ACCOUNTING AND FISCAL AMORTIZATION

    2012-05-01

    Full Text Available Placed in the international trend, Romanian accounting had experienced various changes, especially as regards of progress on disconnection between accounting and fiscality. In the present, fiscal rules should not have any role in accounting decisions, because accounting rules are applied to produce accounting information that is useful in making decisions and to provide a "true and fair view" upon financial reality of the entity. However, the barrier in the habit of accounting to thinking for fiscal point of view all economic transactions remains insurmountable, yet. Starting from this perspective on disconnection between accounting and fiscality would mean that amortization recorded in the accounting, as a result of management policy, to be different from fiscality amortization, to calculate income tax. Although formally accepted, disconnect between accounting and fiscality continues to meet many difficulties. In this sense, it is usual in practice to use the same method of amortization for accounting purposes and for fiscal purposes to prevent complications of double track amortization and prevent wandering in the rules in this field. Accounting rule is deliberately eluded in favor of the fiscal rules. This is the reason we proposed to make in this paper a comparative study between norms and rules on accounting and fiscal amortization, paper in which we intend to show the benefits of applying accounting and fiscal rules separately.

  13. Comparative economic analysis: Anaerobic digester case study

    International Nuclear Information System (INIS)

    An economic guide is developed to assess the value of anaerobic digesters used on dairy farms. Two varieties of anaerobic digesters, a conventional mixed-tank mesophilic and an innovative earthen psychrophilic, are comparatively evaluated using a cost-effectiveness index. The two case study examples are also evaluated using three other investment merit statistics: simple payback period, net present value, and internal rate of return. Life-cycle savings are estimated for both varieties, with sensitivities considered for investment risk. The conclusion is that an earthen psychrophilic digester can have a significant economic advantage over a mixed-tank mesophilic digester because of lower capital cost and reduced operation and maintenance expenses. Because of this economic advantage, additional projects are being conducted in North Carolina to increase the rate of biogas utilization. The initial step includes using biogas for milk cooling at the dairy farm where the existing psychrophilic digester is located. Further, a new project is being initiated for electricity production with thermal reclaim at a swine operation

  14. Assays for mammalian tyrosinase: a comparative study

    International Nuclear Information System (INIS)

    This work describes a comparative study of the tyrosinase activity determined using three methods which are the most extensively employed; two radiometric assays using L-tyrosine as substrate (tyrosine hydroxylase and melanin formation activities) and one spectrophotometric assay using L-dopa (dopa oxidase activity). The three methods were simultaneously employed to measure the activities of the soluble, melanosomal, and microsomal tyrosinase isozymes from Harding-Passey mouse melanoma through their purification processes. The aim of this study was to find any correlation among the tyrosinase activities measured by the three different assays and to determine whether that correlation varied with the isozyme and its degree of purification. The results show that mammalian tyrosinase has a greater turnover number for L-dopa than for L-tyrosine. Thus, enzyme activity, expressed as mumol of substrate transformed per min, is higher in assays using L-dopa as substrate than those using L-tyrosine. Moreover, the percentage of hydroxylated L-tyrosine that is converted into melanin is low and is affected by several factors, apparently decreasing the tyrosinase activity measured by the melanin formation assay. Bearing these considerations in mind, average interassay factors are proposed. Their values are 10 to transform melanin formation into tyrosine hydroxylase activity, 100 to transform tyrosine hydroxylase into dopa oxidase activity, and 1,000 to transform melanin formation into dopa oxidase activity. Variations in these values due to the presence in the tyrosinase preparations of either inhibitors or regulatory factors in melanogenesis independent of tyrosinase are also discussed

    Analyzing data from a survey of African American and White residents in South Carolina, this study attempts to understand how to better promote clinical trial participation specifically within the African American population. To explore why participation is lower in the African American population, the authors examined two sets of potential barriers: structural/procedural (limited accessibility, lack of awareness, doctors not discussing clinical trial options, lack of health insurance) and cognitive/psychological (lack of subjective and factual knowledge, misperceptions, distrust, fear, perceived risk). Findings revealed that African Americans were significantly less willing than Whites to participate in a clinical trial. African Americans also had lower subjective and factual knowledge about clinical trials and perceived greater risk involved in participating in a clinical trial. The authors found that lack of subjective knowledge and perceived risk were significant predictors of African Americans' willingness to participate in a clinical trial. Implications of the findings are discussed in detail. PMID:26042496

    Full Text Available Background/Aim. Left ventricular noncompaction (LVNC is a disorder in endomyocardial morphogenesis, seen either isolated (in the absence of other cardiac anomalies or in association with congenital heart disease and some neuromuscular diseases. Intrauterine arrest of the compaction of myocardial fibers is postulated to be the reason of LVNC. Recognition of this condition is extremely important due to its high mortality and morbidity that lead to progressive heart failure, ventricular arrhythmias and thromboembolic events. The aim of this study was to determine the prevalence and clinical presentation of LVNC among consecutive outpatients according to clinical and echocardiographyic findings. Methode. A total of 3,854 consecutive patients examined at the Institute for Cardiovascular Diseases within a period January 2006 - January 2007 were included in the study. All the patients underwent echocardiographic examination using the same equipment (Vivid 7, GE Medical System. Echocardiographic parameters and clinical presentation in patients with echocardiographic criteria for LVNC were analyzed. Results. Analyzing 3,854 consecutive outpatients, using two-dimensional Color Doppler echocardiography from January 2006 to January 2007, 12 patients met the criteria for LVNC. Seven of them were male. The mean age at diagnosis was 45 ± 15 years. Analyzing clinical manifestation of LVNC it was found that seven patients had signs of heart failure, six had arrhythmias with no embolic events. Conclusion. Our results suggest that the real prevalence of LVNC may be higher than expected. New studies have to be done to solve this problem.

    2015-08-01

    Full Text Available Malaria is a protozoan disease, transmitted by the bite of the infected Anopheles mosquito. There are four species of plasmodia causing the disease, but the two causing the morbidity and mortality are the plasmodium falciparum and the vivax. The disease invariably causes splenomegaly, which can be evaluated and assessed for the better prognosis of the patient. The study shows the evaluation of splenomegaly, both clinically and USG examination. AIMS AND OBJECTIVES: The main aim of this study is to show the prevalence of splenomegaly in malaria and compare with USG examination. MATERIAL AND METHODS: The patients included in the study were suffering from malaria (smear positive belonging to the age group of 15 to 70 years, at Chhattisgarh Institute of Medical Sciences, Bilaspur (CG. The time span of the study was 1 year. Measurement of splenic enlargement was done, both clinical and with ultrasound. The observations were tabulated and assessed. The patients excluded were those having fever and splenomegaly resulting from tropical disease. RESULTS: The USG examination to detect splenomegaly in cases of malaria, is more sensitive and specific as compared to the clinical examination. CONCLUSION: I t is recommended that splenomegaly in malaria should be detected by USG examination as compared to clinical examination.

  1. Achalasia in the elderly patient: a comparative study

    Directory of Open Access Journals (Sweden)

    Rosana B. Schechter

    2011-03-01

    Full Text Available CONTEXT: Achalasia is a primary esophageal motor disorder secondary to the degeneration of ganglion cells of the inhibitory intramural myenteric plexus. It affects both sexes similarly and has two peaks of incidence, one in the 3rd to 4th decades of life and the other after 60 years of age. The effect of age on esophageal motility of patients with achalasia is not well known. Studies have shown that healthy older people, when compared to the young, have: a a lower number of ganglion cells in the intramural myenteric plexus; b a reduced normal relaxation of the lower esophageal sphincter; and c a reduced esophageal peristalsis. Thus, as both age and achalasia can produce comparable degenerative changes in the intramural myenteric plexus, it is possible that advanced age could be an important factor in enhancing the clinical and manometric abnormalities commonly found in patients with achalasia. OBJECTIVES: To compare the clinical, radiological and manometric findings in young as compared to elderly (>60 years old achalasia patients. METHODS: A retrospective study of a group of patients with untreated achalasia separated into young and elderly patients. Demographic, clinical, serology for Chagas' disease, radiological and manometric data were compared between these groups. The level of significance was P<0.05. RESULTS: The study included 105 patients, 52 young (25 M/27 F, mean age 40 years old and 53 elderly (21 M/32 F, mean age 70 years old. The elderly group had a higher prevalence of Chagas' disease (P = 0.004 and a lower pressure of the lower esophageal sphincter [26.4 mm Hg vs 31.9 mm Hg] P = 0.001, a difference that persisted when analyzed only elderly and young patients with idiopathic achalasia.

Aim: This study was to compare the effectiveness of two oral hygiene aids: Chewing stick and manual toothbrush, for plaque removal and gingival health after one month of a randomized clinical trial. Materials and Methods: Dental students (age 18-22 years of a public sector dental hospital were recruited. Sample size was determined using the American Dental Association guidelines. Participants were randomized into two interventional groups and provided with either chewing sticks or toothbrushes. Pre- and post-intervention examinations were executed by two blind and calibrated examiners using plaque and gingival dental indices. Statistical analysis included descriptive statistics, paired t-test, and two sample independent t-tests. Results: Fifty subjects were recruited with mean age 20 ± 0.66 years (80% were females and 20% were males. Except for the mean plaque scores of toothbrush users (which increased at post-intervention examination, all other scores showed reduction. In contrast to the final mean gingival scores, a significant difference (P = < 0.0001 in the final mean plaque score was observed for the two respective interventional groups. Conclusion: Chewing stick has revealed parallel and at times greater mechanical and chemical cleansing of oral tissues as compared to a toothbrush.

    Breathing can lead to organ motions up to several centimeters. For radiotherapy of lung, these motions are generally taken into account by adding a specific margin around the target. Thus, treated volumes are often too large to allow for the high-dose values requested for local control. To manage respiratory motion, deep-inspiration breath-hold technique (DIBH) and gated radiotherapy are starting being used clinically. DIBH consists in asking the patient to perform breath-hold during the treatment and the image acquisition, DIBH level being measured by a spirometer. Gated radiotherapy consists in treating the patient at a certain phase of the free breathing. Linac is synchronized with the motion of a marker' located on the patient chest. Planning images are obtained by a four-dimensional CT (4D-CT) using the same marker. We have assessed the value of these two methods. For lung treatment, compared to a standard treatment, toxicity reduction was mainly due to the lung total volume increase.; It is therefore more significant for breath-hold approach. It is also due to the reduction of safety margins, which is similar for both methods. These two techniques, which have specific advantages and drawbacks, are used routinely at Curie Institute for a large proportion of lung patients, but also for some breast, liver or even Hodgkin disease treatments.

    Aim: To evaluate the efficacy of Ultrasonography compared to clinical diagnosis, radiography and histopathological findings in the diagnosis of maxillofacial swellings. Material and methods: The study was conducted on forty-five patients with maxillofacial swellings. The clinical diagnosis, radiographic diagnosis and ultrasonographic diagnosis were made which was compared to the histopathological diagnosis. The maxillofacial swellings included cystic lesions, benign swellings, malignant swellings, lymphadenopathies and abscesses and space infections. Results: The diagnostic accuracy and contingency coefficient was evaluated considering histopathology as gold standard. The diagnostic accuracy of ultrasound was found to be 92.30% in the diagnosis of cystic lesions, 87.5% in benign tumors, 81.8% in malignant tumors, 100% in lymphadenopathies and 90% in space infections and abscesses. The contingency coefficient of 0.934 was obtained when ultrasonography was compared to the histopathology, which was highly significant. Similar significant results were obtained comparing ultrasonography with clinical diagnosis (0.895) and radiographic diagnosis (0.889). Conclusion: Ultrasonography provides accurate imaging of the head and neck region and provides information about the nature of the lesion, its extent, and relationship with the surrounding structures. As the conventional and digital radiography enable the diagnosis of the presence of the disease, but do not give any indication of its nature. So, together with clinical and histopathological examinations, real time ultrasound imaging works out as a valuable adjunct in the diagnosis of orofacial swellings.

    To compare the clinical performance of digital breast tomosynthesis (DBT) with that of full-field digital mammography (FFDM) in a diagnostic population. The study enrolled 200 consenting women who had at least one breast lesion discovered by mammography and/or ultrasound classified as doubtful or suspicious or probably malignant. They underwent tomosynthesis in one view [mediolateral oblique (MLO)] of both breasts at a dose comparable to that of standard screen-film mammography in two views [craniocaudal (CC) and MLO]. Images were rated by six breast radiologists using the BIRADS score. Ratings were compared with the truth established according to the standard of care and a multiple-reader multiple-case (MRMC) receiver-operating characteristic (ROC) analysis was performed. Clinical performance of DBT compared with that of FFDM was evaluated in terms of the difference between areas under ROC curves (AUCs) for BIRADS scores. Overall clinical performance with DBT and FFDM for malignant versus all other cases was not significantly different (AUCs 0.851 vs 0.836, p = 0.645). The lower limit of the 95% CI or the difference between DBT and FFDM AUCs was -4.9%. Clinical performance of tomosynthesis in one view at the same total dose as standard screen-film mammography is not inferior to digital mammography in two views. (orig.)

    Clinical, haematological and biochemical studies of 34 subjects, occupationally exposed to different types of pesticides, were conducted. The findings have been compared with those observed in 14 control subjects. Inhibition of cholinesterase activity was observed in the exposed group. Serum alkaline phosphatase was also found to be raised. Radiological examination revealed pneumonitic patches in the chest skiagrams of three exposed subjects. Paraesthesia with hyporeflexia was also found in 8.8% of exposed subjects. The findings suggest that exposure to multiple pesticides over many years affects the normal functioning of different organ systems and may produce characteristic clinical effects. PMID:1679651

    International Nuclear Information System (INIS)

    Widely used options for infection detection include traditional imaging procedures like X-ray, ultrasound, CT, MRI complemented with labeled leukocytes or other radiopharmaceuticals which provide anatomic and functional information to localize the foci.However, these methods not always lead to reliable clinical interpretation due to their low specificity and sensitivity. This paper shows the results of a comparative study of two radiolabeled antifungal compounds: Fluconazole and Voriconazole as potential diagnostic agents. Labeling was performed using Triaquotricarbonyltechnetium(I) as precursor, followed by substitution with ligands of interest. Biological studies were performed using CD1 mice and injury models were sterile inflammation, Candida albicans and Aspergillus niger infections. Results show that both complexes present good specificity in differentiating inflammation and infection. Nevertheless, scintigraphic images fail to achieve adequate sensitivity for the detection of these two processes

    Full Text Available This study sought to examine whether the administration of quinfamide at 3- or 6-month intervals diminished the frequency of Entamoeba histolytica cysts in stool samples compared to controls. The prospective, longitudinal, randomized, single-blind study examined children from six primary schools in Celaya and Neutla, Guanajuato. Of the 1,524 students in these schools, we selected participants for the study as follows: Children were included in the study if their parents agreed in writing to the study and if the children demonstrated evidence of E. histolytica cysts after a parasitoscopic analysis by concentration (PSC in three samples over consecutive days using Faust’s method. Those included in the study received a single 4.3-g/kg dose of quinfamide, and we performed PSC on days 5, 6, and 7 following dose administration to examine whether quinfamide had affected the presence of the cysts. The study participants who tested negative for cysts were divided into three groups: Group 1 had 102 patients who underwent quinfamide treatment and three CPS analyses after the 12 months of the study; Group 2 had 98 subjects who underwent the quinfamide treatment and three CPS analyses at months 3, 6, 9, and 12 after their entrance into the study; and Group 3 had 102 patients, who underwent the quinfamide treatment and series of three CPS analyses at months 6 and 12 of the study. All participants received the dose of quinfamide after providing stool samples and after a clinical gastrointestinal history was obtained. Further clinical gastrointestinal data were collected 5 days after the quintamide dose was administered. We used EpiInfo 6.0 for statistical analysis, calculating X2 and p values for the clinical data and the CPS data after the 12 months concluded. Of the initial samples of 1,524 subjects, 308 (20.2% had Entamoebic cysts. Of these, six were further eliminated because they did not meet the inclusion requirements. At the conclusion of the study

  16. Comparative study of anomalous dispersive transparent media

    International Nuclear Information System (INIS)

    We present a comparative theoretical analysis of five different atomic schemes with respect to their performance as negative (anomalous) dispersive transparent media. The schemes discussed are the strongly driven and the degenerate two-level system, two closely spaced gain lines, and two slightly different double-Λ schemes with incoherent pumping. The analysis shows that the degenerate two-level scheme is best suited for applications for which only modest negative dispersion but strongly reduced absorption is required, and dissipation and loss of the optical fields have to be avoided. Two closely spaced gain lines and one of the double-Λ schemes are the best choice for applications which rely on large negative dispersion, but are not too sensitive to residual absorption and dissipation

  17. Comparative study of void fraction models

    International Nuclear Information System (INIS)

    Some models for the calculation of void fraction in water in sub-cooled boiling and saturated vertical upward flow with forced convection have been selected and compared with experimental results in the pressure range of 1 to 150 bar. In order to know the void fraction axial distribution it is necessary to determine the net generation of vapour and the fluid temperature distribution in the slightly sub-cooled boiling region. It was verified that the net generation of vapour was well represented by the Saha-Zuber model. The selected models for the void fraction calculation present adequate results but with a tendency to super-estimate the experimental results, in particular the homogeneous models. The drift flux model is recommended, followed by the Armand and Smith models. (F.E.)

  20. A clinical study of papular urticaria

    International Nuclear Information System (INIS)

    To determine the clinical features and demographic profile of the patients having papular urticaria. Individuals of all age groups and either gender either suspected of or having definite history of insect bite were included in the study. A specially-designed proforma was filled for each patient separately. The proforma included demographic features, information regarding clothing and sleeping habits, personal or family history of atopy and clinical patterns of the lesions. Computer programme SPSS 10 was used to manage and analyze the data. Out of 280 patients, 201 (71.8%) were children upto 12 years of age, 178 (63.6%) were males, 91 (32.5%) had atopy, 194 (69.3%) were non-locals, 212 (75.7%) came from urban/peri-urban areas and 173 (61.8%) presented during May-August. Lesions were present over exposed parts of the body in 36 (12.9%), arranged in groups in 152 (54.3%) and were papular urticaria in 185 (66.1%) patients. Children, adult males, non-locals and those belonging to urban/peri-urban areas are more vulnerable to papular urticaria in a particular region. Papular and urticarial lesions arranged in groups over both exposed as well as covered body parts of a single patient is the most common clinical pattern. (author)

    2016-01-01

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition we study the distributions of the different indices which also behave similarly.

  3. Method validation and clinical utility of chromogenic factor VIII assay compared to one-stage assay.

    Gouws, Wilmare; Botha, Elsabie; Visser, Adele

    2014-01-01

    The chromogenic FVIII assay is currently considered the gold standard for quantitation of factor VIII levels in both haemophilia A patients and as part of screening for thrombophilia. A method validation and evaluation of clinical utility within a routine diagnostic laboratory was undertaken by comparing the currently used one-stage assay to a commercially available chromogenic assay (Siemens, Johannesburg, South Africa). In total, 60 samples were included in this study to encompass the whole diagnostic range of the assay. Both low and high values showed very good correlation on linear regression analysis with correlation coeffients of 0.949 and 0.888 respectively. However, the lower detection limit of the Siemens Chromogenic assay was 1.5 IU/dL rendering it impossible to utilize in the setting of classifying a haemophilia A patient in terms of disease severity. Although the Siemens FVIII chromogenic assay shows excellent correlation to the currently used one-stage assay, the relatively high detection limit restrict implementation as a stand-alone assay in a routine diagnostic laboratory.

    Shtilman, L.; Chasnov, J. R.

    1992-01-01

    We have performed Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) of forced isotropic turbulence at moderate Reynolds numbers. The subgrid scale model used in the LES is based on an eddy viscosity which adjusts instantaneously the energy spectrum of the LES to that of the DNS. The statistics of the large scales of the DNS (filtered DNS field or fDNS) are compared to that of the LES. We present results for the transfer spectra, the skewness and flatness factors of the velocity components, the PDF's of the angle between the vorticity and the eigenvectors of the rate of strain, and that between the vorticity and the vorticity stretching tensor. The above LES statistics are found to be in good agreement with those measured in the fDNS field. We further observe that in all the numerical measurements, the trend was for the LES field to be more gaussian than the fDNS field. Future research on this point is planned.

    2011-03-01

    Full Text Available Detection of edge is a terminology in image processing and computer vision particularly in the areas of feature detection and extraction to refer to the algorithms which aims at identifying points in a digital image at which the image brightness changes sharply or more formally has discontinuities. The need of edge detection is to find the discontinuities in depth, discontinuities in surface orientation, changes in material properties and variations in scene illumination. Remote sensing images are generally corrupted from noise. athematical morphology is a new technique for edge detection .It is a theory and technique for analysis and processing of geometrical structures, based on set theory. In this paper square type structuring element of different size is implemented on different remote sensing images . The noise can also be suppressed by mathematical morphology. So by using mathematical morphology the image can be enhanced and the edges can be detected. In this paper ,the result of edge detection using mathematical morphology will be compared with sobel edge detector, Prewitt edge detector, laplician of gaussian edge detector and Canny edge detector.

  10. A win ratio approach to comparing continuous non-normal outcomes in clinical trials.

    Science.gov (United States)

    Wang, Duolao; Pocock, Stuart

    2016-05-01

    Clinical trials are often designed to compare continuous non-normal outcomes. The conventional statistical method for such a comparison is a non-parametric Mann-Whitney test, which provides a P-value for testing the hypothesis that the distributions of both treatment groups are identical, but does not provide a simple and straightforward estimate of treatment effect. For that, Hodges and Lehmann proposed estimating the shift parameter between two populations and its confidence interval (CI). However, such a shift parameter does not have a straightforward interpretation, and its CI contains zero in some cases when Mann-Whitney test produces a significant result. To overcome the aforementioned problems, we introduce the use of the win ratio for analysing such data. Patients in the new and control treatment are formed into all possible pairs. For each pair, the new treatment patient is labelled a 'winner' or a 'loser' if it is known who had the more favourable outcome. The win ratio is the total number of winners divided by the total numbers of losers. A 95% CI for the win ratio can be obtained using the bootstrap method. Statistical properties of the win ratio statistic are investigated using two real trial data sets and six simulation studies. Results show that the win ratio method has about the same power as the Mann-Whitney method. We recommend the use of the win ratio method for estimating the treatment effect (and CI) and the Mann-Whitney method for calculating the P-value for comparing continuous non-Normal outcomes when the amount of tied pairs is small.

  16. Earthquake correlations and networks: A comparative study

    International Nuclear Information System (INIS)

    We quantify the correlation between earthquakes and use the same to extract causally connected earthquake pairs. Our correlation metric is a variation on the one introduced by Baiesi and Paczuski [M. Baiesi and M. Paczuski, Phys. Rev. E 69, 066106 (2004)]. A network of earthquakes is then constructed from the time-ordered catalog and with links between the more correlated ones. A list of recurrences to each of the earthquakes is identified employing correlation thresholds to demarcate the most meaningful ones in each cluster. Data pertaining to three different seismic regions (viz., California, Japan, and the Himalayas) are comparatively analyzed using such a network model. The distribution of recurrence lengths and recurrence times are two of the key features analyzed to draw conclusions about the universal aspects of such a network model. We find that the unimodal feature of recurrence length distribution, which helps to associate typical rupture lengths with different magnitude earthquakes, is robust across the different seismic regions. The out-degree of the networks shows a hub structure rooted on the large magnitude earthquakes. In-degree distribution is seen to be dependent on the density of events in the neighborhood. Power laws, with two regimes having different exponents, are obtained with recurrence time distribution. The first regime confirms the Omori law for aftershocks while the second regime, with a faster falloff for the larger recurrence times, establishes that pure spatial recurrences also follow a power-law distribution. The crossover to the second power-law regime can be taken to be signaling the end of the aftershock regime in an objective fashion.

    Full Text Available Background: Conjunctivitis of the newborn is defined as hyperemia and eye discharge in the neonates and is a common infection occurring in the neonates in the first month of life. In the United States, the incidence of neonatal conjunctivitis ranges from 1-2%, in India, the prevalence is 0.5-33% and varies in the world from 0.9-21% depending on the socioeconomic status. Aim: To study the organisms causing conjunctivitis of the newborn and to correlate the etiology with the mode of delivery. Design: Single center, prospective, observational study. Materials and Methods: A total of 300 mothers and their newborns, born over a period of one year, were included in the study. Of these 200 newborns were delivered through vaginal route (Group A and 100 (Group B delivered by lower segment caesarean section (LSCS. At the time of labour, high vaginal swabs were taken from the mothers. Two conjunctival swabs each from both eyes of the newborn were collected at birth and transported to Microbiology department in a candle jar immediately. Results: Eight babies in Group A, developed conjunctivitis at birth. None of the babies in Group B developed conjunctivitis, this difference was statistically highly significant (P<0.000. The organisms found in the conjunctiva of the newborns in Group A were Coagulase negative Staphylococcus, α hemolytic Streptococcus, Escherichia coli and Pseudomonas spps. However, the commonest organism leading to conjunctivitis in the newborn in this study was Coagulase negative Staphylococcus. It was observed that the mothers of 5 out of 8 babies (60% developing conjunctivitis gave history of midwife interference and premature rupture of membranes so the presence of risk factors contribute to the occurrence of conjunctivitis in the newborn. Conclusions: It is inferred that the mode of delivery and the presence of risk factors is responsible for conjunctivitis in the newborn.

    Barth Syndrome is a rare X-linked disorder characterized principally by dilated cardiomyopathy, skeletal myopathy and neutropenia and caused by defects in tafazzin, an enzyme responsible for modifying the acyl chain moieties of cardiolipin. While several comprehensive clinical studies of Barth Syndrome have been published detailing cardiac and hematologic features, descriptions of its biochemical characteristics are limited. To gain a better understanding of the clinical biochemistry of this rare disease, we measured hematologic and biochemical values in a cohort of Barth Syndrome patients. We characterized multiple biochemical parameters, including plasma amino acids, plasma 3-methylglutaconic acid, cholesterol, cholesterol synthetic intermediates, and red blood cell membrane fatty acid profiles in 28 individuals with Barth Syndrome from ages 10 months to 30 years. We describe a unique biochemical profile for these patients, including decreased plasma arginine levels. We further studied the plasma amino acid profiles, cholesterol, cholesterol synthetic intermediates, and plasma 3-methylglutaconic acid levels in 8 female carriers and showed that they do not share any of the distinct, Barth Syndrome-specific biochemical laboratory abnormalities. Our studies augment and expand the biochemical profiles of individuals with Barth Syndrome, describe a unique biochemical profile for these patients, and provide insight into the possible underlying biochemical pathology in this disorder.

  6. Clinic-Radiological Study of facial paralysis

    International Nuclear Information System (INIS)

    We have gathered 159 cases of facial paralysis from recent records in our hospital, including paralyses of central as well as peripheral origin, and presenting as the only symptom or as one of several major symptoms of the discomfort of each patient. Sixty-four percent of them were studied by CT scan and/or MR, confirming the existence of alterations in the pathway of nerve pair VII in 50% of the patients who underwent radiological study. Idiopathic facial paralysis was the most common type (42% of the total); while tumors and post-traumatic findings were the most constant radiological findings. From the analysis of the data, the importance of the clinical criteria for selection of the patients in the study and the protocol for radiological diagnosis employed can be deduced. (author)

  7. Actual issues of clinical radiobiology and their experimental study

    International Nuclear Information System (INIS)

    Information being collector for some tens years in frame of clinical study of radiation effects in man in broad range of dose and exposure variant has been summarised and systematized. It has been formulated the questions which could be answered under only clinical observation with many difficulties: diagnostical and prognostical criteria for evaluation of therapy efficiency in non-bonemarrow syndrome of acute radiation disease choice and confirmaty of methods of bonemarrow syndrome therapy in overlethal range of dose; improving of preclinical examination of means and methods of acute radiation syndrome prophylaxis and treatment; comparative analysis of the role of various radiation factory in development of oncological and severe somatic disease and possibility of these effects modification. Some limitations in extrapolation of experimental data onto clinical practice has been discussed and optimal forms of cooperation are shown

    Egress of four important alphaherpesviruses, equine herpesvirus 1 (EHV-1), herpes simplex virus type 1 (HSV-1), infectious laryngotracheitis virus (ILTV), and pseudorabies virus (PrV), was investigated by electron microscopy of infected cell lines of different origins. In all virus-cell systems analyzed, similar observations were made concerning the different stages of virion morphogenesis. After intranuclear assembly, nucleocapsids bud at the inner leaflet of the nuclear membrane, resulting in enveloped particles in the perinuclear space that contain a sharply bordered rim of tegument and a smooth envelope surface. Egress from the perinuclear cisterna primarily occurs by fusion of the primary envelope with the outer leaflet of the nuclear membrane, which has been visualized for HSV-1 and EHV-1 for the first time. The resulting intracytoplasmic naked nucleocapsids are enveloped at membranes of the trans-Golgi network (TGN), as shown by immunogold labeling with a TGN-specific antiserum. Virions containing their final envelope differ in morphology from particles within the perinuclear cisterna by visible surface projections and a diffuse tegument. Particularly striking was the addition of a large amount of tegument material to ILTV capsids in the cytoplasm. Extracellular virions were morphologically identical to virions within Golgi-derived vesicles, but distinct from virions in the perinuclear space. Studies with gB- and gH-deleted PrV mutants indicated that these two glycoproteins, which are essential for virus entry and direct cell-to-cell spread, are dispensable for egress. Taken together, our studies indicate that the deenvelopment-reenvelopment process of herpesvirus maturation also occurs in EHV-1, HSV-1, and ILTV and that membrane fusion processes occurring during egress are substantially different from those during entry and direct viral cell-to-cell spread.

    A 6.9 million-feature oligonucleotide array of the human transcriptome [Glue Grant human transcriptome (GG-H array)] has been developed for high-throughput and cost-effective analyses in clinical studies. This array allows comprehensive examination of gene expression and genome-wide identification of alternative splicing as well as detection of coding SNPs and noncoding transcripts. The performance of the array was examined and compared with mRNA sequencing (RNA-Seq) results over multiple independent replicates of liver and muscle samples. Compared with RNA-Seq of 46 million uniquely mappable reads per replicate, the GG-H array is highly reproducible in estimating gene and exon abundance. Although both platforms detect similar expression changes at the gene level, the GG-H array is more sensitive at the exon level. Deeper sequencing is required to adequately cover low-abundance transcripts. The array has been implemented in a multicenter clinical program and has generated high-quality, reproducible data. Considering the clinical trial requirements of cost, sample availability, and throughput, the GG-H array has a wide range of applications. An emerging approach for large-scale clinical genomic studies is to first use RNA-Seq to the sufficient depth for the discovery of transcriptome elements relevant to the disease process followed by high-throughput and reliable screening of these elements on thousands of patient samples using custom-designed arrays.

    2016-09-01

    Schizophrenia is a pervasive neurodevelopmental disorder that appears to result from genetic and environmental factors. Although the dopamine hypothesis is the driving theory behind the majority of translation research in schizophrenia, emerging evidence suggests that aberrant immune mechanisms in the peripheral and central nervous system influence the etiology of schizophrenia and the pathophysiology of psychotic symptoms that define the illness. The initial interest in inflammatory processes comes from epidemiological data and historical observations, dating back several decades. A growing body of research on developmental exposure to infection, stress-induced inflammatory response, glial cell signaling, structural and functional brain changes and therapeutic trials demonstrates the impact that inflammation has on the onset and progression of schizophrenia. Research in animal models of psychosis has helped to advance clinical and basic science investigations of the immune mechanisms disrupted in schizophrenia. However, they are limited by the inability to recapitulate the human experience of hallucinations, delusions and thought disorder that define psychosis. To date, translational studies of inflammatory mechanisms in human subjects have not been reviewed in great detail. Here, we critically review clinical studies that focus on inflammatory mechanisms in schizophrenia. Understanding the neuroinflammatory mechanisms involved in schizophrenia may be essential in identifying potential therapeutic targets to minimize the morbidity and mortality of schizophrenia by interrupting disease development.

  12. Clinical and neuroradiological studies on internuclear ophthalmoplegia

    International Nuclear Information System (INIS)

    In this study 14 cases of internuclear ophthalmoplegia (INO) were analysed. The correlation of clinical symptoms with localization of the responsible lesions was studied in these patients. The subjects included 9 patients with CVD, 2 with MS, 1 with Fisher's syndrome, 1 with cranial polyneuritis and one with unknown etiology. Nine patients with unilateral INO are all associated with brainstem infarction. The other 5 patients including 2 MS had bilateral INO. CT showed abnormal findings in brain stem in 7 out of 14 patients. As for MRI an abnormality was found in 5 out of the 8 patients examined. Two of the 7 patients without any abnormality on CT had abnormal signals on MRI. We divided INO into 3 groups based on the clinical symptoms: 1) anterior type in which convergence was involved concomitantly with adduction paralysis, 2) typical type in which dissociated nystagmus was more marked in the abducting eye, and convergence was preserved, 3) posterior type in which abduction is impaired without adduction disturbance. There were 5 cases of anterior type, 9 of typical type, and none of posterior type. On MRI two patients of anterior type had abnormalities in the dorsal midbrain, and one patient had an abnormality in the pons, and two patients of typical type had abnormalities in the upper or middle dorsal pons to the dorsal midbrain. CT failed to demontrate any responsible lesions in 2 patients in whom the responsible legions were clearly identified on MRI. (J.P.N.)

    Full Text Available Nosocomial pneumonia is a common complication in patients on mechanical ventilation and results in significant mortality. Diagnosis of pneumonia in patients who are intubated and under mechanical ventilation is difficult, even with the aid of clinical, laboratorial, and endoscopic tests. The objective of this study was to compare three methods of tracheal sputum collection in patients with a clinical and radiological diagnosis of pneumonia. Twenty-two patients with a clinical diagnosis of liver disease were enrolled, 18 years of age or older, 13 males and nine females, who had been mechanically ventilated over an intubation period of 5.86 ± 4.62 days. These patients were being treated in intensive care unit (ICU of the Liver Transplantdepartment. Secretion collection was carried out according to a protocol with three distinct methods: endotracheal aspiration with a closed aspiration system, Bal cath and bronchoalveolar lavage. Of the 22 patients analyzed, 21 (95.4% showed one or more infectious agent when the closed aspiration system was used. With the Bal cathâ collection, 19 patients (86.3% had one or more infectious agents; in the collection by bronchoalveolar lavage, 10 patients (45.4% presented one or more infectious agent. According to the laboratorial analysis, 14 different microorganisms were isolated, the most frequent of which were Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae. We concluded that aspiration with the closed system produced the most effective results in comparison with those of bronchoalveolar lavage and the Bal cathâ, and may be an acceptable method for diagnosing hospital-acquired pneumonia when no fiberoptic technique is available.

    A sporadic outbreak of an unknown disease occurred among dairy cattle, from early February to late May 1955, in Japan. The characteristic symptoms of this disease were dyspnea and depilation; out of 29 cases, 8 died while 2 were slaughtered. Clinical studies have disclosed that the symptoms were similar to those found in cases of mercury poisoning as described by others. So the animals' feed was suspected of being the cause of the sickness. It was confirmed that the incident was due to poisoning resulting from ingestion of linseed meal treated with a mercurial fungicide. From the results of the testing anamnesis, it was found that 171 cattle were fed with the meal and 29 cases were affected. In veiw of the wide use of mercurial preparations for treating seed grains against fungi infection, a further experimental study was made on the effects of the feed and fungicide upon calves.

    Full Text Available Erythema infectiositm is a childhood illness characterized by mild constitutional symptoms and a blotchy or maculo-papular lacy rash on the cheeks (slapped - cheek spreading primarily to the extremities and trunk. The disease- is-caused by human parvovirus B19. Erythema infectiosum epidemics occur in a cyclic fashion, mostly during winter and spring months. The diagnosis of erythema infectiosum is usually based on the appearance and pattern of the rash. The aim of our study was to establish the frequency and clinical characteristics of erythema infectiosum in children, in the period between 2000 and 2004 at the Institute of Child and Youth Health Care, Department of Dermatology, Novi Sad. There were 0.23% of children with a clinical picture of infectious erythema. There was an outbreak of erythema infectiosum from December 2001 to September 2002. The highest number of cases was detected in April and May of 2002. from 2003 to 2004, no cases with infekctious erythema were diagnosed. The average age of infected children was 7.38. Female children were affected slightly more often than male (56.41%:43.58%. Pruritus was detected in 10.26% of children. The most constant clinical sign was reticular exanthema on the limbs, present in 100% of cases, followed by 89.74% of cheek exanthema, while limb and trunk exanthema was present in 7.68% of children. Adenopathies and mild constitutional symptoms were present in 5.12% of children. No complications were recorded in any of the cases. .

    Cardiac mixoma in the elderly. A clinical study. The clinical features of 13 cardiac myxomas surgically resected are presented. The mean age at presentation was 68 years. Ten were in the left atrium, 5 near the fossa ovalis, 3 at the base of the atrial septum, 1 at the inferior wall and 1 on the anterior leaflet of mitral valve, 3 were in the right atrium, 1 of these was accompanied with a myxoma at the apex of left ventricle. The ECG and the chest X-ray were normal in 9 and in 8 patients, respectively. In 3 patients, the diagnosis was occasionally made by routine 2-dimensional echocardiography. 5 patients presented with fever of unknown origin, arthralgias, weakness, weight loss. None had intracardiac or extracardiac recurrence in the 73 months follow-up. The presentation with constitutional symptoms only like fever of UO, may mimic collagen and neoplastic diseases, vasculitis, lymphomas: the 2-dimensional echocardiography is mandatory to esclude a cardiac myxoma in the elderly.

    Background Hypnosis is defined as "as an interaction in which the hypnotist uses suggested scenarios ("suggestions") to encourage a person's focus of attention to shift towards inner experiences". Aim of the work The focus of this review is to summarize the findings of controlled outcome studies investigating the potential of clinical hypnosis in pediatric populations. We will examine the following themes: anesthesia, acute and chronic pain, chemotherapy-related distress, along with other specific medical issues. Results Hypnosis is an effective method to reduce pain and anxiety before, during and after the administration of anesthetics, during local dental treatments, invasive medical procedures and in burn children. Hypnosis can be successfully used to manage recurrent headaches, abdominal pain, irritable bowel syndrome and chemotherapy-related distress. Hypnosis has an important role in managing symptoms and improving the quality of life of children suffering from asthma and cystic fibrosis and in facilitating the treatment of insomnia in school-age children. Finally, hypnosis can be effectively used for the treatment of some habitual disorders such as nocturnal enuresis and dermatologic conditions, including atopic dermatitis and chronic eczema Conclusions Clinical hypnosis seems to be a useful, cheap and side-effects free tool to manage fear, pain and several kinds of stressful experiences in pediatric populations. Children who receive self-hypnosis trainings achieve significantly greater improvements in their physical health, quality of life, and self-esteem. PMID:24165457

  20. Experimental and clinical studies on CT lymphography

    International Nuclear Information System (INIS)

    Indirect lymphography using computed tomographic apparatus (CT Lymphography) was attempted in 15 dogs with newly devised contrast medium for the opacification of hilar and mediastinal lymphnodes. Clinical application was performed in 2 cases of lung cancer. Newly devised contrast material is an emulsion, which consists of oily contrast medium, non-ionic surfactant and glucose solution. The contrast medium was injected percutaneously into subdiaphragmatic space, or into bronchial walls by bronchofiberscopic technique. CT was able to demonstrate the opacified hilar and mediastinal nodes much more in number than demonstrated in conventional radiograms. It was true in 6 to 11 cases when injected into subdiaphragmatic spaces, and in 2 of 4 cases with an injection into bronchial walls. In clinical studies, CT revealed opacification of mediastinal nodes in one case of lung cancer. Although the procedure is still inferior to the demonstrability of routine indirect lymphography for the evaluation of the fine structure of each node, it showed no remarkable side effects. As the satisfactory method of opacifying hilar and mediastinal nodes has not yet been established, our method is thought to be of value in applying for detection of the metastatic lymphnodes.

    Full Text Available Stroke is one of the most common causes of epilepsy in elderly. However, there have been very few prospective studies to define the incidence, pattern and outcome of seizures in stroke. Most studies are based on retrospective analysis of hospital records. Hence, we planned this prospective study to see the clinical, radiological and electroencephalographic characteristics of seizures in stroke and their outcome, from a north Indian tertiary care centre. Over a span of approximately 6 years, 269 consecutive patients with stroke were studied and followed up. Thirty-five (13% of these developed seizures, primarily related to stroke, during mean follow up period of 15.9 months. Twenty of these had infarctions while 15 had haemorrhages. Involvement of the cortical region was seen in most of the patients with seizures. In these patients, 86% of the lesions involved cortical areas exclusively or in addition to subcortical areas on CT scan of the brain. Twenty-seven (77% developed early seizures, two third of them had immediate post-stroke seizures. None of the patients with early onset seizures developed recurrent seizures or epilepsy, while 50% of late onset seizures developed epilepsy. No specific EEG pattern was found in those who later developed epilepsy. In the present study, early onset seizures after stroke were rather common and did not affect outcome and did not recur even when not treated with anti-epileptics. Late onset seizures were less common but were associated with recurrent seizures.

    Full Text Available Pituitary suppression by depot GnRH agonist may be excessive for ovarian stimulation. This study compares the efficacy of a single half-dose depot triptorelin and reduced-dose daily buserelin in a long protocol ICSI/ET. METHODS: A total of 182 patients were randomized into two groups using sealed envelopes. Pituitary desensitization was obtained in group 1 (91 patients with half-dose (1.87 mg depot triptorelin in the mid-luteal phase of their menstrual cycle, and in group 2 (91 patients with standard daily dose (0.5 mg buserelin, which was then reduced to 0.25 mg at the start of human menopausal gonadotropin (HMG stimulation. RESULTS: No significant differences were found among those who received HCG in terms of clinical pregnancy rate (34.4% in both groups, implantation rate (14.8% in group 1 versus 11.1% in group 2, fertilization rate (93.3 versus 95.6%, poor response rate (11.1 versus 6.7%, and miscarriage rate (11.1 versus 7.8%. No significant differences were seen in number of HMG ampoules used, follicles at HCG administration, and oocytes retrieved. The number of days of stimulation was significantly reduced in group 2 (11.2 +/- 1.8 in group 1 versus 10.6 +/- 1.9, p = 0.030. CONCLUSION: A half-dose of depot triptorelin can be successfully used in ovarian stimulation instead of reduced-dose daily buserelin, with more patient comfort and reduced stress and cost of injections.

    Pivmecillinam (PMPC), semisynthetic penicillin for oral use, was studied clinically and following results were obtained. 1) Twenty-eight patients with acute simple cystitis treated with the drug 200 mg/day for 4 days, clinical results were excellent in 23 cases and moderate in 5 cases. Six patients with chronic simple cystitis treated with the drug 400 mg/day for 7 days, clinical results were excellent in 4 cases, moderate in 1 case and poor in 1 case. Eight patients with complicated urinary tract infections treated with the drug 400 mg/day for 7 days, clinical results were excellent in 2 cases, moderate in 2 cases and poor in 4 cases. Overall effectiveness amounted to 88.1%. 2) Pivmecillinam was clinically effective in patients infected by Gram-negative bacteria except Pseudomonas aeruginosa. 3) No side effects were observed in all cases. The effectiveness of PMPC for acute simple cystitis was compared with that of talampicillin (TAPC), ampicillin (ABPC), amoxicillin (AMPC) and pivampicillin (PVPC) reported previously and PMPC was assessed as the most useful agent in these. Then, pivmecillinam should be chosen firstly as a chemotherapeutic agent for acute simple cystitis. PMID:228097

    2015-01-01

    Full Text Available Context: Systemic conditions, especially chronic infections, have a direct impact on the general health and well-being of an individual. Similarly, the long-standing inflammatory changes seen during periodontitis have been associated with the altered diabetic control, preterm, low birth weight infants, and cardiovascular disease. Being a low-grade infection, the signs may not be as severe as seen in other systemic conditions, but they definitely cannot be ignored. Aims: The present study was designed to compare clinical, hematological, and systemic inflammatory markers in patients with chronic periodontitis. Subjects and Methods: A total of 90 chronic periodontitis patients were selected for the present study from the outpatient department of the Department of Periodontology, and the various clinical and hematological parameters were then assessed. Statistical Analysis Used: Z-test was used to compare the probing depth, clinical attachment loss, hematological parameter, and interleukin-6 values between Group A and Group B. Mann-Whitney U-test was used to compare gingival index, plaque index, and bleeding on probing between Group A and Group B. Results: The results of the study were based on the comparison of the clinical, hematological, and systemic inflammatory markers in smokers and nonsmokers with chronic periodontitis and came out to be statistically highly significant. Conclusions: With the resurgence of emphasis on significance of oral diseases related to systemic health, the medical professionals also need to familiarize themselves with the oral cavity and the oral-systemic inter-relationships to treat or reduce the morbidity of the underlying medical condition. Furthermore, the oral health care professionals must reach out to the medical community and the general public to improve patient care through education and communication about the oral health-systemic health link.

  7. Collapsed cone convolution and analytical anisotropic algorithm dose calculations compared to VMC++ Monte Carlo simulations in clinical cases

    International Nuclear Information System (INIS)

    The purpose of this work was to study and quantify the differences in dose distributions computed with some of the newest dose calculation algorithms available in commercial planning systems. The study was done for clinical cases originally calculated with pencil beam convolution (PBC) where large density inhomogeneities were present. Three other dose algorithms were used: a pencil beam like algorithm, the anisotropic analytic algorithm (AAA), a convolution superposition algorithm, collapsed cone convolution (CCC), and a Monte Carlo program, voxel Monte Carlo (VMC++). The dose calculation algorithms were compared under static field irradiations at 6 MV and 15 MV using multileaf collimators and hard wedges where necessary. Five clinical cases were studied: three lung and two breast cases. We found that, in terms of accuracy, the CCC algorithm performed better overall than AAA compared to VMC++, but AAA remains an attractive option for routine use in the clinic due to its short computation times. Dose differences between the different algorithms and VMC++ for the median value of the planning target volume (PTV) were typically 0.4% (range: 0.0 to 1.4%) in the lung and -1.3% (range: -2.1 to -0.6%) in the breast for the few cases we analysed. As expected, PTV coverage and dose homogeneity turned out to be more critical in the lung than in the breast cases with respect to the accuracy of the dose calculation. This was observed in the dose volume histograms obtained from the Monte Carlo simulations

  8. Collapsed cone and analytical anisotropic algorithm dose calculations compared to VMC++ Monte Carlo simulations in clinical cases

    International Nuclear Information System (INIS)

    The purpose of this work was to study and quantify the differences in dose distributions computed with some of the newest dose calculation algorithms available in commercial planning systems. The study was done for clinical cases where large density inhomogeneities were present. Three dose algorithms were used: a pencil beam like algorithm, the anisotropic analytic algorithm (AAA), a convolution superposition algorithm, collapsed cone convolution (CCC) and a Monte Carlo program, voxel Monte Carlo (VMC++). The dose calculation algorithms were compared under static field irradiations at 6 MV and 15 MV using multileaf collimators and hard wedges where necessary. Five clinical cases were studied: three lung and two breast cases. We found that the CCC algorithm performed overall better than AAA compared to VMC++, but AAA remains an attractive option for routine use in the clinic due to its short computation times. Dose differences between the different algorithms for the median value of the planning target volume (PTV) were typically 0.4% (range: 0.0-1.4%) in the lung and -1.3% (range: -2.1--0.6%) in the breast for the few cases we analysed. As expected, PTV coverage and dose homogeneity turned out to be more critical in the lung than in the breast cases with respect to the accuracy of the dose calculation. This was observed in the dose volume histograms obtained from the Monte Carlo simulations

  9. Experimental and clinical studies with intraoperative radiotherapy

    International Nuclear Information System (INIS)

    Studies of normal tissue tolerance to intraoperative radiotherapy were done upon 65 dogs subjected to laparotomy and 11 million electron volt electron irradiation in doses ranging from zero to 5,000 rads. Results of studies indicated that intact aorta and vena cava tolerate up to 5,000 rads without loss of structural integrity. Ureteral fibrosis and stenosis develop at doses of 3,000 rads or more. Arterial anastomoses heal after doses of 4,500 rads, but fibrosis can lead to occlusion. Intestinal suture lines heal after doses of 4,500 rads. Bile duct fibrosis and stenosis develop at doses of 2,000 rads or more. Biliary-enteric anastomoses fail to heal at any dose level. A clinical trial of intraoperative radiotherapy combined with radical surgery was performed upon 20 patients with advanced malignant tumors which were considered unlikely to be cured by conventional therapies and which included carcinomas of the stomach, carcinomas of the pancreas, carcinomas involving the hilus of the liver, retroperitoneal sarcomas and osteosarcomas of the pelvis. All patients underwent resection of gross tumor, followed by intraoperative irradiation of the tumor bed and regional nodal basins. Some patients received additional postoperative external beam radiotherapy. Treatment mortality for combined operation and radiotherapy occurred in four of 20 patients. Postoperative complications occurred in four of the 16 surviving patients. Local tumor control was achieved in 11 of the 16 surviving patients, with an over-all median follow-up period of 18 months. The clinical trial suggested that intraoperative radiotherapy is a feasible adjunct to resection in locally advanced tumors, that the resulting mortality and morbidity is similar to that expected from operation alone and that local tumor control may be improved

    Full Text Available Abstract Background Recent evidence indicates that Gram-negative bacterial pathogens, the most common of which are Pseudomonas spp., Enterobacteriaceae, and Acinetobacter baumannii, are frequent causes of hospital-acquired infections. This study aims to evaluate the in vitro activity of doripenem and comparator carbapenem antibiotics against Gram-negative clinical isolates collected from COMParative Activity of Carbapenem Testing (COMPACT study centres in Turkey. Methods Ten centres in Turkey were invited to submit Pseudomonas aeruginosa, Enterobacteriaceae, and other Gram-negative isolates from intensive care unit (ICU/non-ICU patients with complicated intra-abdominal infections, bloodstream infections, or nosocomial pneumonia, including ventilator-associated pneumonia, between May and October 2008. Susceptibility was determined by each centre using E-test. A central laboratory performed species confirmation as well as limited susceptibility and quality-control testing. Results Five hundred and ninety six isolates were collected. MIC90 values for doripenem, meropenem, and imipenem, respectively, were 32, ≥ 64, and ≥ 64 mg/L against Pseudomonas spp.; 0.12, 0.12, and 0.5 mg/L against Enterobacteriaceae; and ≥ 64 mg/L for each against other Gram-negative isolates. In determining the susceptibility of hospital isolates of selected Gram-negative pathogens to doripenem, imipenem, and meropenem, we found that against all pathogens combined, the MIC90 for ICU compared with non-ICU isolates was higher. Conclusions Doripenem showed similar or slightly better activity than meropenem and better activity than imipenem against the Gram-negative pathogens collected in Turkey.

  11. A Comparative Study of Radiographic Images on Normal Anatomical Structures

    International Nuclear Information System (INIS)

    To compare radiographic images of Digora system and Ektaspeed Plus film obtained from normal adults. Storage phosphor plate (SPP) was placed in a film holder behind Ektaspeed Plus film package without lead foil. The effect of film on SPP was studied in a separate in vitro experiment. Forty-seven sets of images were prepared for the evaluation. The regions of interest (ROI) for evaluation were designated at seven sites including normal anatomical structures. The image quality for each ROI was evaluated on enhanced and unenhanced storage phosphor (SP) images and Ektaspeed Plus film. Two film-SPP configurations showed significantly different grey levels at each step of the aluminum step wedge (p<0.05). The contrasts were comparable. Enhanced SP images were significantly superior to unenhanced images and film in all anatomical structures (p<0.01). The differences between unenhanced SP images and film were significant (p<0.05) except root canal and cortical bone on alveolar crest. For anatomical items, there were statistically significant difference among five observers (p<0.05). The image quality of enhanced SP images were superior to Ektaspeed Plus film, and Digora system is potentially applicable to clinical diagnosis.

    Full Text Available Abstract Background In prognostic research, prediction rules are generally statistically derived. However the composition and performance of these statistical models may strongly depend on the characteristics of the derivation sample. The purpose of this study was to establish consensus among clinicians and experts on key predictors for persistent shoulder pain three months after initial consultation in primary care and assess the predictive performance of a model based on clinical expertise compared to a statistically derived model. Methods A Delphi poll involving 3 rounds of data collection was used to reach consensus among health care professionals involved in the assessment and management of shoulder pain. Results Predictors selected by the expert panel were: symptom duration, pain catastrophizing, symptom history, fear-avoidance beliefs, coexisting neck pain, severity of shoulder disability, multisite pain, age, shoulder pain intensity and illness perceptions. When tested in a sample of 587 primary care patients consulting with shoulder pain the predictive performance of the two prognostic models based on clinical expertise were lower compared to that of a statistically derived model (Area Under the Curve, AUC, expert-based dichotomous predictors 0.656, expert-based continuous predictors 0.679 vs. 0.702 statistical model. Conclusions The three models were different in terms of composition, but all confirmed the prognostic importance of symptom duration, baseline level of shoulder disability and multisite pain. External validation in other populations of shoulder pain patients should confirm whether statistically derived models indeed perform better compared to models based on clinical expertise.

  15. Iohexol and iopamidol myelography in the dog: a clinical trial comparing adverse effects and myelographic quality

    International Nuclear Information System (INIS)

    In a blind clinical trial, adverse effects after iohexol and iopamidol myelography were evaluated in 151 dogs. Eighty-one dogs were given iohexol (240 mgI/ml) and 70 dogs were given iopamidol (200 mgI/ml) by pre-determined assignment. Each dog was evaluated postmyelographically for seizures, hyperthermia, prolonged recovery from anesthesia and intensification of pre-existing neural signs. Myelographic quality was evaluated with a subjective scoring method. In comparing iohexol and iopamidol groups, there was not a statistically significant difference in the incidence of adverse effects or in myelographic quality. Iopamidol and iohexol appeared to be equally efficacious for routine canine myelography

  16. Atherosclerotic Plaque Destabilization in Mice: A Comparative Study.

    Directory of Open Access Journals (Sweden)

    Helene Hartwig

    Full Text Available Atherosclerosis-associated diseases are the main cause of mortality and morbidity in western societies. The progression of atherosclerosis is a dynamic process evolving from early to advanced lesions that may become rupture-prone vulnerable plaques. Acute coronary syndromes are the clinical manifestation of life-threatening thrombotic events associated with high-risk vulnerable plaques. Hyperlipidemic mouse models have been extensively used in studying the mechanisms controlling initiation and progression of atherosclerosis. However, the understanding of mechanisms leading to atherosclerotic plaque destabilization has been hampered by the lack of proper animal models mimicking this process. Although various mouse models generate atherosclerotic plaques with histological features of human advanced lesions, a consensus model to study atherosclerotic plaque destabilization is still lacking. Hence, we studied the degree and features of plaque vulnerability in different mouse models of atherosclerotic plaque destabilization and find that the model based on the placement of a shear stress modifier in combination with hypercholesterolemia represent with high incidence the most human like lesions compared to the other models.

  17. Uremic pruritus. Clinical and experimental studies.

    Ståhle-Bäckdahl, M

    1989-01-01

    The aim of the study was to investigate clinical aspects of pruritus in maintenance hemodialysis patients and to evaluate factors of putative pathogenic importance. 60-65% of the patients in a maintenance hemodialysis program during a two-year period suffered from itching. Patients with pruritus tended to have been on dialysis treatment longer than those without pruritus (p = 0.05), otherwise there was no difference in clinical data or routine laboratory tests. Measurement of itch intensity continuously over one week in 28 patients using a computerized method showed that itching peaked at night after two days without dialysis, was relatively high during treatment and lowest during the day following dialysis. Our results suggest that the accumulation of pruritogens between dialysis sessions influences the intensity of itching. Most patients had "dry" skin. Recording of the stratum corneum water content by measurement of electrical capacitance, in 31 patients (19 with pruritus) and 12 controls, disclosed no significant difference between dialysis patients and controls, but a tendency that pruritic patients had a lower water content than the other subjects. In different body areas, there was a positive correlation in all groups between the clinical estimation of xerosis and hydration. Serum concentrations of parathyroid hormone (PTH) were significantly higher in dialysis patients with pruritus than in those without, but there was no correlation between the degree of symptoms and the PTH level. Indirect immunohistochemistry revealed no immunoreactivity for different parts of the PTH molecule in skin biopsies from uremic patients. Intradermal injections of PTH fragments did not evoke itching or other cutaneous reactions in patients or controls. Our results do not support PTH as a peripheral mediator of uremic itching. Flare reactions induced by intradermal histamine injections were significantly smaller in 26 dialysis patients (18 with pruritus) than in 9 healthy

  18. Clinical application of cerebral dynamic perfusion studies

    International Nuclear Information System (INIS)

    Radionuclide cerebral perfusion studies are assuming a far greater importance in the detection and differential diagnosis of cerebral lesions. Perfusion studies not only contribute to the differential diagnosis of lesions but in certain cases are the preferred methods by which more accurate clinical interpretations can be made. The characteristic blood flow of arterio-venous malformations readily differentiates this lesion from neoplasms. The decreased perfusion or absent perfusion observed in cerebral infarctions is diagnostic without concurrent evidence from static images. Changes in rates and direction of blood flow contribute fundamental information to the status of stenosis and vascular occlusion and, in addition, offer valuable information on the competency and routes of collateral circulation. The degree of cerebral perfusion after cerebral vascular accidents appears to be directly related to patient recovery, particularly muscular function. Cerebral perfusion adds a new parameter in the diagnosis of subdural haematomas and concussion and in the differentiation of obscuring radioactivity from superficial trauma. Although pictorial displays of perfusion blood flow will offer information in most cerebral vascular problems, the addition of computer analysis better defines temporal relationships of regional blood flow, quantitative changes in flow and the detection of the more subtle increases or decreases in cerebral blood flow. The status of radionuclide cerebral perfusion studies has taken on an importance making it the primary modality for the diagnosis of cerebral lesions. (author)

    Full Text Available Statement of Problem: Various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (SCTG is identified as one of the most successful techniques. Recently, acellular dermal matrix allograft (ADMA has been developed as a substitute for SCTG to avoid removing the palatal connective tissue.Purpose: The present study compared the clinical efficiency of ADMA and SCTG in the treatment of recession defects.Materials and Methods: This randomized controlled clinical study, consisted of nine patients with 32 Miller’s class I or II recession defects of ≥ 2 mm on the facial aspects of premolar teeth. Bleeding on Probing Index (BPI, Plaque Index (PI, Probing Depth (PD, Recession Depth (RD, Recession Width and Clinical Attachment Level (CALwere measured at baseline and 6, 12 and 24 weeks post-surgery. Before operation, the samples were randomly allocated to ADMA (test or SCTG (control groups.Results: A statistically significant improvement was observed in RD, RW and CAL,but not in BPI, PI and PD. The mean values of changes in all clinical parameters from baseline to 24 weeks postsurgery were not significantly different between the two groups. There was no significant difference in the amount of mean root coveragebetween the ADMA (85.42% and SCTG (69.05% groups (P= 0.058.Conclusion: ADMA may be a useful substitute for SCTG in the treatment of shallow to moderate gingival recessions, if the financial aspect is not an issue for the patient.

    Full Text Available The identification and longitudinal assessment of traumatic brain injury presents several challenges. Because these injuries can have subtle effects, efforts to find quantitative physiological measures that can be used to characterize traumatic brain injury are receiving increased attention. The results of this research must be considered with care. Six reasons for cautious assessment are outlined in this paper. None of the issues raised here are new. They are standard elements in the technical literature that describes the mathematical analysis of clinical data. The purpose of this paper is to draw attention to these issues because they need to be considered when clinicians evaluate the usefulness of this research. In some instances these points are demonstrated by simulation studies of diagnostic processes. We take as an additional objective the explicit presentation of the mathematical methods used to reach these conclusions. This material is in the appendices. The following points are made:1. A statistically significant separation of a clinical population from a control population does not ensure a successful diagnostic procedure.2. Adding more variables to a diagnostic discrimination can, in some instances, actually reduce classification accuracy.3. A high sensitivity and specificity in a TBI versus control population classification does not ensure diagnostic successes when the method is applied in a more general neuropsychiatric population. 4. Evaluation of treatment effectiveness must recognize that high variability is a pronounced characteristic of an injured central nervous system and that results can be confounded by either disease progression or spontaneous recovery. A large pre-treatment versus post-treatment effect size does not, of itself, establish a successful treatment.5. A procedure for discriminating between treatment responders and nonresponders requires, minimally, a two phase investigation. This procedure must include a

    Full Text Available Background: Congenital talipes equinovarus is a common foot deformity afflicting children with reported incidence varying from 0.9/1000 to 7/1000 in various populations. The success reported with Ponseti method when started at an early age requires an imaging modality to quantitate the deformity. Sonography being a radiation free, easily available non-invasive imaging has been investigated for this purpose. Various studies have described the sonographic anatomy of normal neonatal foot and clubfoot and correlated the degree of severity with trends in sonographic measurements. However, none of these studies have correlated clinical, radiographic and sonographic parameters of all the component deformities in clubfoot. The present study aims to compare the radiographic and sonographic parameters in various grades of clubfoot. Materials and Methods: Thirty-one children with unilateral clubfoot were examined clinically and graded according to the Demeglio system of classification of clubfoot severity. Antero-posterior (AP and lateral radiographs of both normal and affected feet were obtained in maximum correction and AP talo-calcaneal (T-C, AP talo-first metatarsal (TMT and lateral T-C angles were measured. Sonographic examination was done in medial, lateral, dorsal and posterior projections of both feet in static neutral position and after Ponseti manouever in the position of maximum correctability in dynamic sonography. Normal foot was taken as control in all cases. The sonographic parameters measured were as follows : Medial malleolar- navicular distance (MMN and medial soft tissue thickness (STT on medial projection, calcaneo-cuboid (C-C distance, calcaneo-cuboid (C-C angle and maximum length of calcaneus on lateral projection, length of talus on dorsal projection; and tibiocalcaneal (T-C distance, posterior soft tissue thickness and length of tendoachilles on posterior projection. Also, medial displacement of navicular relative to talus, mobility

However, few data are available on the effect of thrombectomy on clinical outcome. Thus we have designed a collaborative individual patient-data meta-analysis which aimed to assess the long-term clinical outcome in STEMI patients randomized to percutaneous coronary intervention (PCI with or without thrombectomy.Method: After a thorough database search, the principal investigators of randomized trials comparing thrombectomy with standard PCI in patients with STEMI were contacted. Principal investigators as authors of 11 randomized studies agreed to participate and were asked to complete a structured database by providing a series of key pre-PCI clinical and angiographic data as well as the longest available clinical outcome of the patients enrolled in the corresponding trial. The primary end-point of this pooled analysis is the comparison of overall survival rates between patients randomized to PCI with thrombectomy or PCI without thrombectomy. The secondary end-points are survival free from myocardial infarction (MI, target lesion revascularization (TLR, major adverse coronary events (MACE: death + MI + TLR and death + MI between patients randomized to PCI with thrombectomy or PCI without thrombectomy. A pre-defined subgroup analysis is planned considering the following variables: type of thrombectomy device used, diabetes, rescue PCI, IIb/IIIa-inhibitors use, time-to-reperfusion, infarct-related artery, and pre-PCI TIMI flow.Implications: This

    To describe clinical features and seizure dispersion in precatamenial/pericatamenial epilepsy patients. Present study included 33 untreated pericatamenial (n: 23, age: 12-40 years, menstrual cycles: 147) and precatamenial (n: 10, age: 13-32 years, menstrual cycles: 70) epileptics with tonic-clonic seizures. Clinical features and seizure dispersion were evaluated during premenstruation, menstruation, and postmenstruation phases. Women with precatamenial epilepsy had highly significant mean phase day seizures during premenstruation versus other phases, whereas women with pericatamenial epilepsy did not show any significant variations. Premenstrual seizures were found significantly more and others as significantly less in % number in precatamenials compared to those in pericatamenials. Furthermore, precatamenial epileptics with primary generalized seizures were significantly higher in % number and secondary generalized seizures as significantly lower against those in pericatamenial epileptics. All precatamenial epileptics under study had incontinence compared to 65% pericatamenial epileptics that had incontinence. Majority of the patients in both groups showed post-ictal headache. The present report describes the extent of exacerbation of premenstrual tonic-clonic seizures with clinical features. These investigations may help in understanding partly the complexity of catamenial/precatamenial/ pericatamenial/noncatamenial seizures, and similarities and dissimilarities between pericatamenial and precise precatamenial seizures.

    1997-11-01

    Bioplastique is a biphasic polymer for the permanent augmentation of some soft tissues. It was developed in 1987, and clinical studies at this institution were begun in 1990. The combination of low molecular weight polyvinylpyrrolidone and solid polymer particles allows the implantation of permanent polymer spheres through a small needle under local anesthesia. In this study 127 cases are reviewed of consecutive patients who have received Bioplastique for scar revision, wrinkles, and augmentation for soft-tissue defects at 6 years after application. All patients who had not been in for follow-up recently were contacted by mail and questioned on the permanence of augmentation and migration of particles. About 30 percent of the patients were unreachable and had their charts reviewed for permanence and migration of particles. In eight of these cases, Bioplastique was removed because of overcorrection, two of them may have had infection. Bioplastique has gained wide use throughout the world and although some complications have been reported, in general, it functions quite well when used in selected cases. PMID:9385974

  10. Clinical study of the stunned myocardium

    International Nuclear Information System (INIS)

    Clinical features of 37 cases of stunned myocardium were studied. Mean duration of asynergy was 22.6±15.7 days. In all 11 cases of unstable angina without any significant serum creatine kinase leakage, the duration of asynergy was within 14 days. Related coronary lesions were reperfused (spontaneously or by interventional therapy) to TIMI grade II or higher. Transient Q waves were observed in 39% of all cases. Negative T waves tended to be prolonged, and persisted after disappearance of asynergy in 74% of all cases. 201Tl uptake in the stunned area varied widely between individual cases (ranging from 'absent' to 'normal'), although it became normal in all cases in the chronic stage. Maldistribution of 99mTc-pyrophosphate (PYP) to the endocardial side of the stunned area was observed in 33%. In 186 cases of acute coronary syndrome, we studied whether or not reversibility of ischemia-disturbed myocardium could be predicted by simultaneous dual isotope SPECT, and found that 201Tl-uptake in the chronic stage significantly improved in the region showing absence of 99mTc-PYP accumulation or maldistribution of 99mTc-PYP to the endocardial side, while reversibility of the region showing transmural 99mTc-PYP accumulation and a dought pattern was poor. Ischemia-associated myocardial damage recovered to various degrees, and dual isotope SPECT was useful in evaluating the reversibility of such damage already at the acute stage. (author)

    2015-01-01

    Independent and supplementary prescribing are the two main forms of non-medical prescribing (NMP) that have been practised in the UK since 2006. Most available studies have qualitatively investigated the impact of NMP, especially in primary care. This may be due to the fact that prescriptions are issued mainly by general practitioners in primary care. This PhD thesis aimed at investigating the clinical effectiveness of independent pharmacist and diabetes specialist nurse (DSN) prescribers in ...

    Full Text Available Abstract Background Although synovial sarcoma is the 3rd most commonly occurring mesenchymal tumor in young adults, usually with a highly aggressive clinical course; remarkable differences can be seen regarding the clinical outcome. According to comparative genomic hybridization (CGH data published in the literature, the simple and complex karyotypes show a correlation between the prognosis and clinical outcome. In addition, the connection between DNA ploidy and clinical course is controversial. The aim of this study was using a fine-tuning interpretation of our DNA ploidy results and to compare these with metaphase high-resolution CGH (HR-CGH results. Methods DNA ploidy was determined on Feulgen-stained smears in 56 synovial sarcoma cases by image cytometry; follow up was available in 46 cases (average: 78 months. In 9 cases HR-CGH analysis was also available. Results 10 cases were found DNA-aneuploid, 46 were DNA-diploid by image cytometry. With fine-tuning of the diploid cases according to the 5c exceeding events (single cell aneuploidy, 33 cases were so called "simple-diploid" (without 5c exceeding events and 13 cases were "complex-diploid"; containing 5c exceeding events (any number. Aneuploid tumors contained large numbers of genetic alterations with the sum gain of at least 2 chromosomes (A-, B- or C-group detected by HR-CGH. In the "simple-diploid" cases no or few genetic alterations could be detected, whereas the "complex-diploid" samples numerous aberrations (equal or more than 3 could be found. Conclusions Our results show a correlation between the DNA-ploidy, a fine-tuned DNA-ploidy and the HR-CGH results. Furthermore, we found significant correlation between the different ploidy groups and the clinical outcome (p

    Full Text Available Abstract Background The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS and the Infectious Disease Society of America (IDSA regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. Methods/Design This study is a prospective multi-center randomized investigation. The study will be performed in the Departments of General, Emergency, and Transplant Surgery of Sant'Orsola-Malpighi University Hospital in Bologna, Italy, in the General Surgery Department of the Ospedali Riuniti of Bergamo, Italy, and in the Trauma and Emergency Surgery Department of Maggiore Hospital in Bologna, Italy, and will be conducted by all surgeons willing to participate in the study. The inclusion period of the study will take approximately two years before the planned number of 142 enrolled patients is reached. Discussion Ertapenem and Ampicillin-sulbactam are recommended both as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines. As one of the discussed topic is the optimal duration of the antibiotic therapy and this ambiguity is due mainly to the lack of clinical trials on the topic, the present study aims for obtain precise data.

  15. Comparative international studies of osteoporosis using isotope techniques

    International Nuclear Information System (INIS)

    In-Vivo Neutron Activation Analysis (IVNAA) and Dual Energy X-ray Absorptiometry (DEXA) are routinely used in our laboratory for clinical and research investigation of Bone Mineral Content (BMC) and Bone Mineral Density (BMD in g/sq.cm). These two techniques differ in many respects. IVNAA is an established technique where 49Ca radioisotope induced by the 48Ca(n,gamma)49Ca reaction is measured to determine BMC. In DEXA, two X-rays of different energies are used and based on the known attenuation characteristics of bone and soft tissue and the measured attenuated signals, the BMC is calculated. Very little radiation dose (<0.1 mSv) is given in DEXA compared to IVNAA (3 to 5 mSv). Site specific information can be obtained in the former. Although DEXA is easier to use both the techniques are in use in the investigation of Osteopenia. The BMD, a clinical useful parameter, is a function of age and not height. The body calcium content determined by IVNAA is a function of height and not age. These differences are not yet clearly understood. Work is underway to determine the influence of several factors e.g. age, weight on BMD. We are also conducting experiments to determine the peak BMC and BMD of Canadians. The role of various life styles e.g. exercise, diet, ethnicity are being investigated as a determinant of BMD and BMC. Also the effects and safety of many drugs in the treatment of osteopenia and osteoporosis are also being studied. (author)

  16. Comparative study of conformal versus intensity modulated radiotherapy treatment plans

    International Nuclear Information System (INIS)

    Full text: In order to establish some early clinical experience in the use of intensity modulated radiotherapy (IMRT) as an alternative treatment method to conformal irradiation, we selected a number of specifically difficult clinical cases to compare. Complex tumour shapes located in the skull (two cases), close to the spinal cord (two cases) and one standard prostate case were chosen for this study. A Varian CadPlan system is used for the conformal treatment plans and Helios for the IMRT plans. In both these techniques, the linear accelerator multileaf collimator system is used to shape the beam about the target volume. The Royal North Shore Hospital Varian Clinac 600C/D linear accelerator also has dynamic multileaf collimator control (DMLC) capabilities for IMRT. The five cases reported here were planned by the radiation therapists for conformal treatment and then re-planned by physics using the CadPlan's Helios inverse planning option to produce an alternative IMRT plan. Both planners worked independently of each other. Treatment set-up errors were not considered as part of this study but it is apparent here that positional errors and immobilisation are particularly important factors to consider. An allowance for all errors must therefore be included for all critical organ outlines as well as the target volume for both the conformal or IMRT treatments. Visually, the covering of regularly shaped treatment volumes for the IMRT plans was improved marginally over the conformal plan. However, complex treatment volumes (such as the posterior orbital region with surrounding critical structures) showed very clear improvements. The IMRT dose drop-off at the edge of the target volume was not as sharp as the conformal equivalent. The dose-volume-histogram (DVH) provides a limited analytical tool to quantify these observations. The DVH generally indicated similar curves for the IMRT and conformal target volume but significant IMRT improvements in limiting the dose to

    Introduction: A key attribute of a learning health care system is the ability to collect and analyze routinely collected clinical data in order to quickly generate new clinical evidence, and to monitor the quality of the care provided. To achieve this vision, clinical data must be easy to extract and stored in computer readable formats. We conducted this study across multiple organizations to assess the availability of such data specifically for comparative effectiveness research (CER) and quality improvement (QI) on surgical procedures. Setting: This study was conducted in the context of the data needed for the already established Surgical Care and Outcomes Assessment Program (SCOAP), a clinician-led, performance benchmarking, and QI registry for surgical and interventional procedures in Washington State. Methods: We selected six hospitals, managed by two Health Information Technology (HIT) groups, and assessed the ease of automated extraction of the data required to complete the SCOAP data collection forms. Each data element was classified as easy, moderate, or complex to extract. Results: Overall, a significant proportion of the data required to automatically complete the SCOAP forms was not stored in structured computer-readable formats, with more than 75 percent of all data elements being classified as moderately complex or complex to extract. The distribution differed significantly between the health care systems studied. Conclusions: Although highly desirable, a learning health care system does not automatically emerge from the implementation of electronic health records (EHRs). Innovative methods to improve the structured capture of clinical data are needed to facilitate the use of routinely collected clinical data for patient phenotyping. PMID:25848594

    2014-04-01

    Full Text Available BACKGROUND: Several clinical studies have reported that significant number of patients receiving non depolarizing muscle relaxants during general anesthesia show postoperative residual neuromuscular block when assessed by neuromuscular monitor in the recovery room. The degree of residual neuromuscular block produced by non-depolarizing muscle relaxants can be evaluated by clinical tests as well as by neuromuscular monitoring y neuromuscular monitor in the recovery room. A randomized double blind clinical trial to determine and compare the incidence of postoperative residual neuromuscular block in patients receiving pancuronium and atracurium applying Train of Four ratio using Train of Four- Guard neuromuscular monitor. AIMS AND OBJECTIVES: To compare the incidence of postoperative residual neuromuscular block following pancuronium and atracurium using Train of Four Ratio in the recovery room. MATERIALS AND METHODS: Comparative randomized study done using 100 patients of age between 15-60 years belonging to either sex, ASA grade 1 and 2 with GROUP ‘P’ – Pancuronium was employed as the muscle relaxant, GROUP ‘A’ – Atracurium was employed as the muscle relaxant. Statistical analysis done using student “t” test. RESULTS: The mean duration required to attain Train of Four Ratio of 0.80 in patients with initial Train of four ratio <0.80 in group ‘P’ was 9.65±5.4413 min and in group ‘A’ was 2.8± 1.4832 min. CONCLUSION: 1. Our study concludes that the incidence of residual neuromuscular block in patients receiving pancuronium and atracurium were 40% and 10% respectively. Thus residual neuromuscular block can be a significant problem in recovery room, during the postoperative period. 2. The use of intermediate acting non depolarizing muscle relaxant like atracurium lowers the incidence of residual neuromuscular block but does not eliminate it.

    Full Text Available Extensive use of praziquantel for treatment and control of schistosomiasis requires a comprehensive understanding of efficacy and safety of various doses for different Schistosoma species.A systematic review and meta-analysis of comparative and non-comparative trials of praziquantel at any dose for any Schistosoma species assessed within two months post-treatment. Of 273 studies identified, 55 were eligible (19,499 subjects treated with praziquantel, control treatment or placebo. Most studied were in school-aged children (64%, S. mansoni (58%, and the 40 mg/kg dose (56%; 68% of subjects were in Africa. Efficacy was assessed as cure rate (CR, n=17,017 and egg reduction rate (ERR, n=13,007; safety as adverse events (AE incidence. The WHO-recommended dose of praziquantel 40 mg/kg achieved CRs of 94.7% (95%CI 92.2-98.0 for S. japonicum, 77.1% (68.4-85.1 for S. haematobium, 76.7% (95%CI 71.9-81.2 for S. mansoni, and 63.5% (95%CI 48.2-77.0 for mixed S. haematobium/S. mansoni infections. Using a random-effect meta-analysis regression model, a dose-effect for CR was found up to 40 mg/kg for S. mansoni and 30 mg/kg for S. haematobium. The mean ERR was 95% for S. japonicum, 94.1% for S. haematobium, and 86.3% for S. mansoni. No significant relationship between dose and ERR was detected. Tolerability was assessed in 40 studies (12,435 subjects. On average, 56.9% (95%CI 47.4-67.9 of the subjects receiving praziquantel 40 mg/kg experienced an AE. The incidence of AEs ranged from 2.3% for urticaria to 31.1% for abdominal pain.The large number of subjects allows generalizable conclusions despite the inherent limitations of aggregated-data meta-analyses. The choice of praziquantel dose of 40 mg/kg is justified as a reasonable compromise for all species and ages, although in a proportion of sites efficacy may be lower than expected and age effects could not be fully explored.

    Full Text Available Fistula in Ano is a benign treatable lesion of the rectum and the anal canal. Cryptoglandular infection accounts for about 90% of these cases. Majority of the infections are Acute and a minority contributed by chronic low grade infection hence pointing to varying etiologies. The pathogenesis has been attributed to the bursting open of an acute or inadequately treated Anorectal abscess into the peri anal skin. Diagnosis of the condition can be made easily with a good source of light, a proctoscope and a meticulous digital examination. Establishing a cure in this condition is difficult owing to two reasons. Firstly, the site of the infection makes the patient reluctant to subject themselves to examination. Secondly, a significant percent of these diseases persist or recur when appropriate surgery is not done or when the post op care is inadequate. Mostly it affects the young and the middle age group thus affecting productive man hours and quality of life. MATERIALS AND METHODS: All cases of clinically diagnosed Fistulae-in-ano above the age of 12 years, admitted in various surgical units in K.R.

    DNA of 258 patients with treatment-resistant depression was collected in three 8-10 week, two-arm, prospective clinical trials. Forty-four allelic variations were measured in genes for the cytochrome P450 (CYP) enzymes CYP2D6, CYPC19, and CYP1A2, the serotonin transporter (SLC6A4), and the 5-HT2A receptor (HTR2A). The combinatorial pharmacogenomic (CPGx™) GeneSight test results were provided to clinicians to support medication changes from baseline (guided arm), or they were provided at the end of each study to clinicians of unguided patients who were treated as usual (TAU). TAU subjects who at baseline were prescribed medications genetically discordant for them showed only a 12% symptom improvement, far less than the 32.5% or 28.5% improvements of the TAU subjects on yellow-category ('use with caution'; p = 0.002) or green-category medications ('use as recommended'; p = 0.02), respectively. The odds of a clinical response were increased 2.3-fold among all GeneSight-guided compared to all TAU subjects (p = 0.004), and overall, the guided group had a 53% greater improvement in depressive symptoms (p = 0.0002), a 1.7-fold relative improvement in response (p = 0.01), and a number needed to treat for one clinical response above that seen in the TAU group of 6.07.

    Using rhenium colloid kit, RI-lymphography was performed in 70 patients, with malignant lymphoma, uterine cervix cancer, urogenital cancer, pelvic tumor, metastatic tumor of the lymphnode, lymphedema, and patients with post-traumatic chyluria. In 36 patients, lymphography was performed and the findings were compared with those of RI-lymphography. Lymphography was very difficult to perform in some patients, especially in severe lymphedema patients, and it needed operation with local anesthesia. Lymphography was one of the important procedures for the staging of the malignant lymphoma, but it's importance has been declined, because the images of the X-ray computed tomography are more convenient for the staging determination of these patients. RI-lymphography is a simple and safe examination without danger of fat embolism, and needs no operation and local anesthesia. Compared with lymphography, the quality of the lymphnodes images is slightly poor in RI-lymphography, but it is proper to see the physiological flow of the lymphatics, because it is not a pressure flow. Rhenium colloid labeled with /sup 99m/Tc-O/sub 4/ can penetrate lymphatic canals easily, and accumulate well in lymphnodes. We compared the images of RI-lymphography and lymphography, and clinical efficacy of the former was discussed.

    The clinical practices provide the students with a good opportunity to study the practical experiences in their field through the clinical training education in hospital. Now, in this study, comparing the perceptions of the clinic teachers with those of students at the clinical site. The study was conducted to the students attending universities located in Seoul and who finished the clinical practices in 2013. The questionnaires were distributed to the student and collected from them. The study were conducted to 275 questionnaires with frequency analysis, crosstabs, chi-square test and McNemar test. The major motivation was of the select radiography course was high employment rate(44.0%) and the satisfaction of radiography course was general(53.1%). 51.3% of the study answered 8 weeks current duration of clinical practices is proper. The 3-year course students answered that the period of clinical practices would be proper if it is performed in the winter vacation in their second year in college(47.3%). The 4-year course students answered that the first semester in their third years is proper for clinical practices(27.7%). The students answered that they felt the lack in their knowledge on the professional field(32.4%) during the clinical practices and some of the practical training is different from the education performed at school(68.4%). Most of answered that they were satisfied with the clinical practices and among them they recognized the importance of the clinical practices (3.94 ± 0.89). After the clinical practices, their desire for getting job as a radiography has changed from 84.1% to 82.9%. The reason why they want the job related to the radiation is because the job is stable (changed from 49.0% to 46.0% after the clinical practice) while the reason why they do not want be a radigrapher because that job is not proper for them (changed from 37.0% to 40.7% after the clinical practice) The effort should be made to enhance the position of radiation

    Electroencephalography (EEG) testing in clinical labs makes use of large amplifiers and complex software for data acquisition. While there are new ambulatory electroencephalogram (EEG) systems, few have been directly compared to a gold standard system. Here, an ultra-low power wireless EEG system designed by Imec is tested against the gold standard Neuroscan SynAmps2 EEG system, recording simultaneously from the same laboratory cap prepared with electrode gel. The data was analyzed using correlation analysis for both time domain and frequency domain data. The analysis indicated a high Pearson's correlation coefficient (mean=0.957, median=0.985) with high confidence (mean P=0.002) for 10-second sets of data transformed to the frequency domain. The time domain results had acceptable Pearson's coefficient (mean=0.580, median =0.706) with high confidence (mean P=0.008). PMID:24109914

    2016-07-01

    Objective The clinical part of this study aimed to investigate whether the racemate of delmopinol [(±)-delmopinol] is equivalent to its two enantiomers [(+)-delmopinol and (-)-delmopinol] with respect to efficiency and to determine and compare their pharmacokinetic properties. The purpose of the pre-clinical part was to elucidate possible differences in antimicrobial efficiency. Materials and methods The compounds were tested clinically in a double-blind, randomized, cross-over study comprising three treatment periods of 4 days each. The antimicrobial efficacy of the enantiomers was compared in vitro with respect to planktonic and biofilm bacteria of different species. Results No statistically significant differences in prevention of plaque formation were observed. Except for a somewhat higher systemic exposure in terms of AUC and Cmax indicated for (-)-delmopinol compared to (+)-delmopinol, the pharmacokinetic properties were similar. The most common adverse event was a transient anaesthetic feeling in the mouth. This event was reported with the same frequency for all three test solutions. The enantiomers showed similar antimicrobial effects on planktonic bacteria and their biofilms. Conclusions The enantiomers were found to be equally effective with respect to inhibition of plaque development and only minor differences were observed with respect to their pharmacokinetic properties. No differences could be observed in the adverse events reports. There is, therefore, no reason to use one of the enantiomers of delmopinol instead of the racemate. This was further supported by the antimicrobial tests. It is suggested that the combined action of cationic and neutral delmopinol is important for its effect on biofilms. PMID:26940371

    Full Text Available NTRIDUCTION : Stroke is one of the important causes of morbidity and mortality all over the world. Incidence of stroke steadily increases with age. Experts are concerned of the emerging stroke epidemic in India. Stroke affecting the young has potentially devastating consequence son the individual and his family. Certain risk factors are unique to the young. I t needs more studies for identification and modification of risk factors. The study aims to evaluate clinical features, risk factors, etiology and mortality of stroke in young patients. METHODS : 74 young patients satisfying the inclusion criteria were included in this study. A detailed history was taken from young stroke patients, systemic examination and required investigations were done. Data was collected in standardized proforma and analysed. RESULTS: Stroke in young accounts for 7.95% of stroke cases of all age groups. The mean age of the patients was 34.66 ± 7.48 years. Among 74 patients, 47(63.51% were male and 27(36.49% were female. Seizures, decreased consciousness, speech involvement and motor deficit were observed in 33.78%, 44.59%, 22.97% and 100% of cases respectively. 82.43% patients had ischemic and 17.57% patients had hemorrhagic stroke. Among ischemic stroke, large artery atherosclerosis was 16.21%, tuberculous meningoencephalitis with vasculitis was 16.21%, lacunar stroke was 10.81%, CVT was 10.81% and cardio embolic stroke was 6.76%. Smoking (59.45%, alcoholism (58.10%, hypertension (43.24%, coronary artery disease (8.10%, diabetes mellitus (10.81%, elevated total cholesterol (25.67%, elevated low density lipo proteins (22.97%, elevated triglycerides (27.02% and low HDL (22.97% were important risk factors. Carotid doppler was abnormal in 9.45% of patients. 6.76% patients had mitral stenosis in echocardiogram. Low protein C and protein S were found in 1.35% of patients. Eight (10.81% patients died during the hospital stay. INTERPRETATION AND CONCLUSIONS: The major risk

    Full Text Available There is no cancer that is common anywhere that is not are somewhere else . This applied to oesophageal carcinoma particularly to its dramatic feature in varying incidence in different parts of the world. T he aetiology of this disease is still an enigma, so many factors being responsible for causation of the disease. The epidemiological study in high incidence are like iran, north west china, Afghanistan showed the different factor were responsible for the prevalence of the disease.in our country also, the frequency with it occurs varies in diffent parts. The average life expectancy of untreated patients with carcinoma oesophagus is only a few months to a maximum of 1 year. By the time the patient presents with dysphagia, usually the disease has extended beyond the curable limits. This is particularly due to the close relationship to other vital mediastinal structures. Nevertheless due to the advent of new techniques in radiology early detection of the disease is now possible. There has been a change in treatment modalities also in the form newer surgical techniques, radiotherapy and chemotherapy. There has been an increase in prognostic index in recent years. As this disease is common in this part of the country, an attempt has been made to analyse the various aetiological factors, clinicopathological correlation and various treatment modalities. All these cases were studied carefully, thoroughly investigated and treated appropriately. R elevant literature was reviewed and an attempt of comparative study also has been done. .

    The paper discusses how current methodological debates on the potentials of Comparative Area Studies intersect with current trends in transitional justice research. As the field of transitional justice studies is approximating a status of maturation, academic enterprises tend to focus on empirical as well as theoretical generalization. The challenge of comparative transitional justice research consists less in weighing national impacts of policies than in taking into account a more historiciz...

    Full Text Available Background: Aggressive periodontitis is a characterized by rapid attachment loss, bone destruction and familial aggregation. Platelet-rich plasma (PRP has been proposed to promote regeneration of the lost periodontal tissues. The aim of this study was to evaluate and compare the efficacy of PRP combined with hydroxyapatite (HA graft in the treatment of intra-bony defects in localized aggressive periodontitis (L-AgP patients. Materials and Methods: Ten L-AgP patients having bilateral intra-bony defect ≥2 mm and probing depth (PD ≥6 mm were randomly treated either with the PRP/HA graft or HA graft alone. The clinical (plaque control record, bleeding on probing index, PD, and relative attachment level [RAL], and radiographic parameters (size of the bone defect were recorded pre- and post-operatively at 3, 6, and 12 months. Results: After 12 months, for both maxillary and mandibular arches, the mean PD decrease was significantly more (P < 0.05 for the test group than the control group (3.2 mm vs. 1.9 mm and 3.6 mm vs. 1.9 mm, respectively. Furthermore, the mean RAL decrease in both maxillary and mandibular arches was significantly more (P < 0.05 for the test group than the control group (3.0 mm vs. 1.2 mm and 3.1 mm vs. 1.4 mm, respectively. Radiographically, the test group showed significantly more defect fill as compared with the control group. Conclusion: Both treatments provided significant improvements in clinical and radiographic parameters in a 12-month postoperative period. PRP/HA group presented superior results regarding PD reduction, clinical attachment gain and radiographic bone fill than HA group.

    During the last decades component-resolved diagnostics either as singleplex or multiplex measurements has been introduced into the field of clinical allergology, providing important information that cannot be obtained from extract-based tests. Here we review recent studies that demonstrate clinical applications of the multiplex microarray technique in the diagnosis and risk assessment of allergic patients, and its usefulness in studies of allergic diseases. The usefulness of ImmunoCAP ISAC has been validated in a wide spectrum of allergic diseases like asthma, allergic rhinoconjunctivitis, atopic dermatitis, eosinophilic esophagitis, food allergy and anaphylaxis. ISAC provides a broad picture of a patient's sensitization profile from a single test, and provides information on specific and cross-reactive sensitizations that facilitate diagnosis, risk assessment, and disease management. Furthermore, it can reveal unexpected sensitizations which may explain anaphylaxis previously categorized as idiopathic and also display for the moment clinically non-relevant sensitizations. ISAC can facilitate a better selection of relevant allergens for immunotherapy compared with extract testing. Microarray technique can visualize the allergic march and molecular spreading in the preclinical stages of allergic diseases, and may indicate that the likelihood of developing symptomatic allergy is associated with specific profiles of sensitization to allergen components. ISAC is shown to be a useful tool in routine allergy diagnostics due to its ability to improve risk assessment, to better select relevant allergens for immunotherapy as well as detecting unknown sensitization. Multiplex component testing is especially suitable for patients with complex symptomatology. PMID:27196983

    Multiple cases with various types of pediatric malabsorption syndromes were evaluated. The clinical manifestations, laboratory findings, pathophysiology, and histopathological descriptions of each patient were analyzed in an effort to clear the pathogenesis of the malabsorption syndromes and the treatments were undertaken. The cases studied, included one patient with cystic fibrosis, two with lactose intolerance with lactosuria (Durand type), one with primary intestinal lymphangiectasia, two with familial hypobetalipoproteinemia, one with Hartnup disease, one with congenital chroride diarrhea, one with acrodermatitis enteropathica, one with intestinal nodular lymphoid hyperplasia (NLH), five with intractable diarrhea of early infancy and four with glycogenosis type Ia. Each case description and outcome is described below: 1. A 15-year-old Japanese boy with cystic fibrosis presented with severe symptoms, including pancreatic insufficiency, bronchiectasis, pneumothorax and hemoptysis. His prognosis was poor. Analysis of the CFTR genes of this patient revealed a homozygous large deletion from intron 16 to 17b. 2. In the sibling case of Durand type lactose intolerance, the subjects'disaccaridase activity of the small bowel, including lactase, were within normal limits. The results of per oral and per intraduodenal lactose tolerance tests confirmed lactosuria in both. These observations suggested, not only an abnormal gastric condition, but also duodenal and intestinal mucosal abnormal permeability of lactose. 3. In the case of primary intestinal lymphangiectasia, the subject had a lymphedematous right arm and hand, a grossly coarsened mucosal pattern of the upper gastrointestinal tract (identified via radiologic examination) and the presence of lymphangiectasia (confirmed via duodenal mucosal biopsy). The major laboratory findings were hypoalbuminemia, decreased immunoglobulin levels and lymphopenia resulting from loss of lymph fluid and protein into the gastro
