    Centrifugal pumps have become important devices for cardiopulmonary bypass and circulatory assistance. Five types of centrifugal pumps are clinically available in Japan. To evaluate the blood trauma caused by centrifugal pumps, a comparative hemolysis study was performed under identical conditions. In vitro hemolysis test circuits were constructed to operate the BioMedicus BP-80 (Medtronic, BioMedicus), Sarns Delphin (Sarns/3M Healthcare), Isoflow (St. Jude Medical [SJM]), HPM-15 (Nikkiso), and Capiox CX-SP45 (Terumo). The hemolysis test loop consisted of two 1.5 m lengths of polyvinyl chloride tubing with a 3/8-inch internal diameter, a reservoir with a sampling port, and a pump head. All pumps were set to flow at 6 L/min against the total pressure head of 120 mm Hg. Experiments were conducted simultaneously for 6 h at room temperature (21 degrees C) with fresh bovine blood. Blood samples for plasma-free hemoglobin testing were taken, and the change in temperature at the pump outlet port was measured during the experiment. The mean pump rotational speeds were 1,570, 1,374, 1,438, 1,944, and 1,296 rpm, and the normalized indexes of hemolysis were 0.00070, 0.00745, 0.00096, 0.00066, 0.00090 g/100 L for the BP-80, Sarns, SJM, Nikkiso, and Terumo pumps, respectively. The change in temperature at the pump outlet port was the least for the Nikkiso pump (1.8 degrees C) and the most with the SJM pump (3.8 degrees C). This study showed that there is no relationship between the pump rotational speed (rpm) and the normalized index of hemolysis in 5 types of centrifugal pumps. The pump design and number of impellers could be more notable factors in blood damage.

    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

    AIM To compare a group of patients with consecutive exotropia with patients who had ≤10 prism diopters (PD) esotropia or no deviation postoperatively in terms of probable clinical risk factors for the development of consecutive exotropia. METHODS The study recruited fourteen patients who developed consecutive exodeviation during follow-up period after the correction of esotropia who were categorized as group 1 and thirty-one patients who had still ≤10 PD esotropia or no deviation at the final visit that were considered as group 2. Clinical risk factors leading the development of consecutive deviation were analyzed as the main outcome measures. RESULTS The mean age of patients was 4.57±3.11y in group 1 and 5.10±3.52y in group 2 (P=0.634). There was no significant difference of preoperative near and distant deviations among two groups (P=0.835, 0.928 respectively). The mean amount of medial rectus recession and lateral rectus resection was similar in both groups (P=0.412, 0.648 respectively). Convergence insufficiency and neurological diseases were more frequent in group 1 (P=0.007, 0.045). Accompanying neurological disease was found to be as a significant factor increasing the risk of the development of consecutive exotropia significantly [odds ratios (OR): 5.75 (1.04-31.93)]. CONCLUSION Accompanying neurological disease appears to be a significant clinical risk factor for the development of consecutive exodeviation during postoperative follow-up after the correction of esotropia. However, larger studies are needed in order to interpret the results to the clinical practice and to ascertain other concurrent risk factors. PMID:27366693

    Full Text Available BACKGROUND: Accurate determination of fetal birth weight prior to delivery can have significant bearing on management decision in labor, thereby markedly improving perinatal outcome. OBJECTIVE: To assess fetal weight in term pregnancy by different clinical and ultrasonographical methods. MATERIALS AND METHODS: The study was conducted in Obstetrics and Gynecology department of Dr. D.Y. Patil Medical College, Pimpri, Pune. Two hundred (200 women were selected and studied for a period of one year based on convenience sampling from October 2011 to September 2013.The fetal weight was estimated a week prior to the delivery by both ultrasound and clinical examination. Various formulae’s for estimation of fetal weight were applied based on Ultrasound and clinical parameters. All results arising from different formulas were studied and suitable statistics was applied and compared to have clear idea regarding results. RESULTS: All results arising from different formulas were studied by Descriptive statistics and compared with Actual weight at the time of delivery (gold standard. A box plot was used to differentiate various methods used for estimation of fetal weight, It shows that Johnson, Dawn formula and weight in gms (Dare’s formula corresponds with the base line indicating that they can predict birth weight correctly and among these Johnson showed promising results, whereas formulas like Campbell, Comb’s, Hadlock and Warsof didn’t predict birth weight as accurately as the three clinical methods used, thus in our study it can be seen that clinical methods are better predictors of birth weight than ultrasonographic methods. CONCLUSIONS: In our study it was observed that Clinical methods used for estimation of fetal birth weight was found to be by far simple and reliable methods in estimation of fetal birth weight than Ultrasonographic estimation methods and thus holds importance in day to day practice especially in countries like us where still

  14. 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.

    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 aim of this study was to evaluate the clinical long-term performance of a visible light-cured resin (VLCR) denture base material and to compare it to a well-established polymethylmethacrylate (PMMA)-based denture acrylic in a randomized split-mouth clinical long-term study. One hundred removable partial dentures in 90 patients, with at least two saddles each, were investigated. One saddle was made of VLCR, while the other was made of PMMA at random. Plaque adhesion, tissue reaction, and technical parameters of the dentures were assessed 6, 12, and 18 months after treatment. Statistical analysis was performed using the Wilcoxon rank-sum test. Though VLCR showed higher plaque adhesion than PMMA after 6, 12, and 18 months (p denture acrylic and metal and the boundary between denture acrylic and denture tooth PMMA was rated higher than VLCR. The surface quality of the upper side of the denture saddles showed no significant differences (p > 0.05). Neither VLCR nor PMMA showed discoloration at any point in time (p > 0.05). It can be concluded that VLCR is a viable alternative for the production of removable dentures. Especially in patients with hypersensitivities to PMMA, VLCR is particularly suitable for clinical use.

    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).

    Full Text Available This paper highlights the problem of neuroendocrine tumours (NETs with clinical symptoms of hypercorticism caused by hypersecretion of adrenocorticotropic hormone (ACTH by tumour cells. In most cases (85%, the tumours were localized in the pituitary gland (Cushing's disease; 15% of the patients had an extrapituitary tumour that manifest as an ectopic ACTH secretion (EAS. Comparative analysis of clinical, hormonal, histological, and immunohistochemical characteristics of pituitary and extrapituitary ACTH-secreting NET was performed. It included 46 patients with CD and 38 ones exhibiting ectopic ACTH secretion (EAS. Results of the study suggest differences between CD and EAS in terms of the severity of clinical manifestations and duration of the disease. Hormonal studies showed that EAS unlike CD was associated with high plasma ACTH and cortisol levels, late-evening salivary cortisol and daily urinary free cortisol, the absence of a 60% or greater reduction of cortisol in the HDDST test, and the presence of a low (less than 2 ACTH gradient in response to desmopressin administration with catheterization of cavernous sinuses. The study of morphofunctional characteristics of the removed NET demonstrated the ability of both pituitary and extrapituitary NETs to express ACTH as well as GH, PRL, LH, and FSH. The angiogenic markers (CD31 and VEGF were detected with equal frequency regardless of the NET localization. The histological structure of all corticotropinomas suggested their benign origin, but extrapituitary NETs were represented by different morphological types with varying malignancy, invasiveness, and metastatic properties. A higher cell proliferation potential (Ki-67 was documented for NET in patients presenting with an ectopic ACTH secretion compared to those having corticotropinomas.

    The centrifugal pump is now widely used in open heart surgery for its clinical benefits related to the blood elements and the coagulation system. The purpose of this study was to compare the clinical performances of and the outcomes offered by 4 types of centrifugal pumps. For each pump, we investigated the effects on the blood elements, coagulation system, complements, and immunoglobulins during open heart surgery. Four types of centrifugal pumps were used: the HPM-15 (Nikkiso Co.), the Capiox (Terumo Co.), the Lifestream (St. Jude Medical Co.), and the BP-80 (Medtronic, BioMedicus Co.). The platelet count, lactate dehydrogenase (LDH), antithrombin III (AT III), thrombin-antithrombin complex (TAT), complements (C3, C4, and CH50), and immunoglobulins (IgG, IgA, and IgM) were measured before and after cardiopulmonary bypass (CPB). The platelet count was decreased more significantly by the HPM-15 than by any of the other pumps. The other parameters showed no difference among the 4 pumps. In clinical use, each of the 4 types of centrifugal pumps was safe.

Both thymus vulgaris and ibuprofen were effective to reduce the pain severity of dysmenorrhea. Before treatment, the mean pain intensity in thymus vulgaris, ibuprofen and placebo groups were 6.57±2.02, 5.30±2.23 and 6.18±1.78, respectively and after treatment decreased to 1.21±1.06, 1.48±1.62 and 3.54±2.26, respectively. Reduction of pain severity was not statistically significant between the two medications, however it was significant for each drug compared with placebo (p<0.001). Conclusion: The results suggest that thymus vulgaris as well as ibuprofen can be effective in reducing the severity of pain and spasm in primary dysmenorrhea. PMID:24778782

    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

  5. Comparative study of clinical, pathological and HRCT findings of primary alveolar proteinosis and silicoproteinosis

    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.

    Objective To characterize the differences between clinical manifestations in immunocompromised patients (ICPs) and non-immunocompromised patients (non-ICPs) with tuberculosis.Methods Underlying diseases, clinical presentations, misdiagnosis, treatment and prognosis, etc, were analyzed retrospectively in 115 tuberculosis patients, including 39 ICPs and 76 non-ICPs.Results Compared with non-ICPs, the individuals who were ICP had more expectoration (64.1% vs 35.5%), pulmonary moist rale (41.0% vs 9.2%), miliary pulmonary tuberculosis (30.8% vs 2.6%), pleural effusion (48.7% vs 25.0%) and lymphadenopathy (18.0% vs 4.0 %). ICPs had less lung cavity (15.4% vs 22.4%) and pleural thickening (15.4% vs 23.7%) compared to non-ICPs. Pulmonary tuberculosis in ICPs was prone to be misdiagnosed as pneumonia (23.1% vs 6.6%). Pulmonary tuberculosis was found in the apicoposterior segment (SI+SII) in more cases in non-ICPs (21.7%, 10/46) than ICPs (10.3%, 3/29). The diagnostic value of tuberculin skin test and adenosine deaminase in pleural effusions was limited in ICPs. ICPs had significantly poorer prognoses than non-ICPs.Conclusion The clinical manifestations of ICPs with tuberculosis are atypical, misdiagnosis often occurs, resulting in a worse prognosis.

    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 Abstract Background Great variability in breast cancer (BC treatment practices according to patient, tumour or organisation of care characteristics has been reported but the relation between these factors is not well known. In two French regions, we measured compliance with Clinical Practice Guidelines for non-metastatic BC care management and identified factors associated with non-compliance at clinical and organisational levels. Methods Eligible patients had invasive unilateral BC without distant metastases and at least two contacts with one of the two regional healthcare systems (2003-2004 in the first year after diagnosis. Medical data were collected from patient medical records in all public and private hospitals (99 hospitals. The care process was defined by 20 criteria: clinical decisions for treatment and therapeutic procedures. Each criterion was classified according to level of compliance ("Compliant", "Justifiable" and "Not Compliant" and factors of non-compliance were identified (mixed effect logistic regression. Results 926 women were included. Non-compliance with clinical decisions for treatment was associated with older patient age (OR 2.1; 95%CI: 1.3-3.6 and region (OR 3.0; 95%CI: 1.2-7.4. Non-compliance with clinical decisions for radiotherapy was associated with lymph node involvement or the presence of peritumoural vascular invasion (OR 1.5; 95%CI: 1.01-2.3 and non-compliance with overall treatment (clinical decisions for treatment + therapeutic procedures was associated with the presence of positive lymph nodes (OR 2.0; 95%CI: 1.2-3.3, grade III versus grade I (OR 2.9; 95%CI: 1.4-6.2, and one region of care versus another (OR 3.5; 95%CI: 1.7-7.1. Finally, heterogeneity of compliance in overall treatment sequence was identified between local cancer units (p Conclusion This study provides interesting insights into factors of non-compliance in non-metastatic BC management and could lead to quality care improvements.

  13. 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

    Full Text Available Psoriasis is one amongst the most common skin disorders encountered in clinical practice. It is a chronic relapsing and remitting disease of skin causing social isolation, cosmetic and psychological embarrassment as well as difficulties in leading social life. Even though it can be considered as an autoimmune disorder affecting skin, it cannot always be treated as a somatic lesion, it is in fact multifactorial in origin and conditioned by various constitutional and environmental factors. Ekakusta is a Raktapradoshaja, vatakapha pradhana tridoshaja kshudra kushta. It bears a greater resemblance with Psoriasis. The current treatment modalities have their own limitations and the drugs have considerable side effects when used for a longer period. Therefore, there is a need for more comprehensive, economical and safe method of management of Psoriasis. Hence the present study was conducted on 60 patients assigned into two equal groups to evaluate the efficacy of shodhana in terms of virechana followed by Guggulu tiktaka gritha shamana sneha and only Guggulu Tiktaka Gritha shamana sneha with the external application of kutajasuryapaki taila in the management of Ekakusta w.s.r to Psoriasis.

  19. Dentin hypersensitivity clinical study comparing LILT and LEDT keeping the same irradiation parameters

    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

    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.

  1. 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.

    [Purpose] To study preoperative and postoperative hip circumference data of various types of congenital dysplasia of the hip treated with total hip replacement, including the femoral offset, femoral neck length, height, and hip abductor arm parameters. [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

A half-mouth design was conducted to compare two in-office bleaching techniques (with and without light activation: G1: 35% hydrogen peroxide (HP (Lase Peroxide - DMC Equipments, São Carlos, SP, Brazil + hybrid light (HL (LED/Diode Laser, Whitening Lase II DMC Equipments, São Carlos, SP, Brazil; G2: 35% HP; G3: 38% HP (X-traBoost - Ultradent, South Jordan UT, USA + HL; G4: 38% HP; and G5: 15% carbamide peroxide (CP (Opalescence PF - Ultradent, South Jordan UT, USA. For G1 and G3, HP was applied on the enamel surface for 3 consecutive applications activated by HL. Each application included 3x3' HL activations with 1' between each interval; for G2 and G4, HP was applied 3x15' with 15' between intervals; and for G5, 15% CP was applied for 120'/10 days at home. A spectrophotometer was used to measure color change before the treatment and after 24 h, 1 week, 1, 6, 12, 18 and 24 months. A VAS questionnaire was used to evaluate tooth sensitivity before the treatment, immediately following treatment, 24 h after and finally 1 week after. RESULTS: Statistical analysis did not reveal any significant differences between in-office bleaching with or without HL activation related to effectiveness; nevertheless the time required was less with HL. Statistical differences were observed between the results after 24 h, 1 week and 1, 6, 12, 18 and 24 months (intergroup. Immediately, in-office bleaching increased tooth sensitivity. The groups activated with HL required less application time with gel. CONCLUSION: All techniques and bleaching agents used were effective and demonstrated similar behaviors.

    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 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.

    Study Design We performed a multicentric, randomized, comparative clinical trial. Eligible patients were randomly assigned to receive 150 mg of Tolperisone thrice daily or 8 mg of Thiocolchicoside twice daily for 7 days. Purpose To assess the efficacy and tolerability of Tolperisone in comparison with Thiocolchicoside in the treatment of acute low back pain with spasm of spinal muscles. Overview of Literature No head on clinical trial of Tolperisone with Thiocolchicoside is available and so this study is done. Methods The assessment of muscle spasm was made by measuring the finger-to-floor distance (FFD), articular excursion in degrees on performing Lasegue's maneuver and modified Schober's test. Assessment of pain on movement and spontaneous pain (pain at rest) of the lumbar spine was made with the help of visual analogue scale score. Results The improvement in articular excursion on Lasegue's maneuver was significantly greater on day 3 (p = 0.017) and day 7 (p = 0.0001) with Tolperisone as compared to Thiocolchicoside. The reduction in FFD score was greater on day 7 (p = 0.0001) with Tolperisone. However there was no significant difference in improvement in Schober's test score on day 3 (p = 0.664) and day 7 (p = 0.192). The improvement in pain score at rest and on movement was significantly greater with Tolperisone (p = 0.0001). Conclusions Tolperisone is an effective and well tolerated option for treatment of patients with skeletal muscle spasm associated with pain. PMID:22708015

    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.

    Recently, Eclipse treatment planning system (TPS) version 8.8 was upgraded to the latest version 13.6. It is customary that the vendor gives training on how to upgrade the existing software to the new version. However, the customer is provided less inner details about changes in the new software version. According to manufacturer, accuracy of point dose calculations and irregular treatment planning is better in the new version (13.6) compared to the old version (8.8). Furthermore, the new version uses voxel-based calculations while the earlier version used point dose calculations. Major difference in intensity-modulated radiation therapy (IMRT) plans was observed between the two versions after re-optimization and re-calculations. However, minor difference was observed for IMRT cases after performing only re-calculations. It is recommended TPS quality assurance to be performed after any major upgrade of software. This can be done by performing dose calculation comparisons in TPS. To assess the difference between the versions, 25 clinical cases from the old version were compared keeping all the patient data intact including the monitor units and comparing the differences in dose calculations using dose volume histogram (DVH) analysis. Along with DVH analysis, uniformity index, conformity index, homogeneity index, and dose spillage index were also compared for both versions. The results of comparative study are presented in this paper. PMID:27651566

    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.

    Background Osteoarthritis (OA) is the most common joint disease and leading cause of disability. Intra-articular (IA) administration of hyaluronic acid (HA) or corticosteroids (CS) have been previously studied, though using insufficient number of patients or short follow-up periods. Objective We evaluate HA and CS in patients with knee OA in terms of clinical efficacy over 12 months. Methods We used a prospective, randomized study with parallel groups. Randomized patients received IA injections of HA or betamethasone (BM). The primary outcomes were improvement in pain using Visual Analog Scale and function in the Western Ontario and McMaster University Osteoarthritis Index (Likert scale). Follow-up visits were scheduled at 3 months, 6 months, 9 months, and 12 months. Results A total of 200 patients were included. Pain was significantly reduced in both groups at the first follow-ups. At 12 months, the mean pain reduction in the HA group was 33.6% (95% CI: 31.1–36.1) compared to 8.2% (95% CI: 5.2–11.1) in BM (P<0.0001). Function improvement was higher in HA through every visit, and mean improvement at 12 months was 47.5% (95% CI: 45.6–49.3) in HA patients vs 13.2% (95% CI: 11.4–14.9) in the BM group (P<0.0001). All patients from both groups achieved the Minimal Clinically Important Improvement (MCII) for both pain and function up to 6 months. At 9 months and 12 months, the MCII figures were higher in HA group with ≥80% compared to ≤10% in BM group (P<0.0001). Adverse reactions were rare and related to the administration procedure. Conclusion Both treatments effectively controlled OA symptoms. BM showed higher short-term effectiveness, while HA showed better long-term effectiveness, maintaining clinical efficacy in a large number of patients 1 year after administration.

    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

    Full Text Available CONTEXT: Fetal malnutrition is a major problem in developing countries like India. It is associated with increased mortality and long term sequel . There are various methods to determine nutritional status of newborns like weight for gestational age, Ponderal index, Body mass index, mid arm circumference/ head circumference ratio etc., but each have their own limitations. The terms fetal malnutrition and small for gestational age are not synonymous and one may occur without the other. Clinical assessment of nutrition al status score (CAN Score developed by Metcoff is a reliable test for identification of fetal malnutrition. This study was under taken to identify incidence of fetal malnutrition by CAN Score and to compare it with other anthropometric indices. METHODS: It was a prospective study conducted in a tertiary care hospital. 256 neonates were assessed using CAN Score and anthropometry was recorded. Neonates were classified as per weight for age. Ponderal index, body mass index, mid arm circumference/ head circum ference ratio, body mass index were calculated and compared with CAN Score for accuracy in identifying fetal malnutrition. RESULTS: Incidence of fetal malnutrition as per CAN Score was 26.17%, 6.4% of Appropriate for gestational age babies were malnourishe d. Weight for age parameter classified 28.52% of babies as malnourished; Ponderal index classified 23.44% as malnourished, body mass index and mid arm circumference/ head circumference ratio classified 39.45% and 34.38% neonates as malnourished respectivel y. Weight for age and body mass index had sensitivity of 83.58% and 80.6% respectively in identifying fetal malnutrition. CONCLUSION: CAN score is a simple clinical method for identification of fetal malnutrition without use of any sophisticated equipments and it can even detect malnourished babies who are missed by other anthropometric methods

    OBJECT Intraoperative language mapping is traditionally performed with low-frequency bipolar stimulation (LFBS). High-frequency train-of-five stimulation delivered by a monopolar probe (HFMS) is an alternative technique for motor mapping, with a lower reported seizure incidence. The application of HFMS in language mapping is still limited. Authors of this study assessed the efficacy and safety of HFMS for language mapping during awake surgery, exploring its clinical impact compared with that of LFBS. METHODS Fifty-nine patients underwent awake surgery with neuropsychological testing, and LFBS and HFMS were compared. Frequency, type, and site of evoked interference were recorded. Language was scored preoperatively and 1 week and 3 months after surgery. Extent of resection was calculated as well. RESULTS High-frequency monopolar stimulation induced a language disturbance when the repetition rate was set at 3 Hz. Interference with counting (p = 0.17) and naming (p = 0.228) did not vary between HFMS and LFBS. These results held true when preoperative tumor volume, lesion site, histology, and recurrent surgery were considered. Intraoperative responses (1603) in all patients were compared. The error rate for both modalities differed from baseline values (p language errors (articulatory, anomia, paraphasia) did not differ between the 2 stimulation methods (p = 0.279). CONCLUSIONS With proper setting adjustments, HFMS is a safe and effective technique for language mapping.

    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.

    Full Text Available Background: Various studies worldwide suggest that human leukocyte antigen (HLA region may be involved in the genetic susceptibility of vitiligo but little information is available from India. Aim: To find the HLA associated susceptibility to develop vitiligo in Indian patients and to detect role of HLA in familial vitiligo. Methods: This was a case controlled study which included all patients suffering from vitiligo over a period of one and half years. Clinical details were noted and sera collected from these patients were screened for the presence of HLA class I antibodies. The clinical features and HLA antigens were assessed and comparison was made between patients with familial and nonfamilial vitiligo. Results: Out of 114 patients studied, 84 had family history and 30 had no family history. Patients with family history of vitiligo have higher chances of acquiring vitiligo if first degree relatives are affected compared to if second degree relatives are affected. Family history of vitiligo is associated with an early onset of vitiligo (< 20 years. There was no statistically significant difference in the type, stability, and severity of vitiligo in both the groups. HLA results in both the groups revealed increase in HLA A2, A11, A31, A33, B17, B35, B40, and B44 alleles while HLA A9, B13, and B53 alleles were decreased. Family history was associated with HLA A2, A28, A31, and B44 alleles. Early onset of vitiligo (< 20 years was significantly associated with HLA A2, A11, B17, B35, and B44 alleles. The patients with severe affection (> 10% area showed in significant association with HLA A10 and B8. Conclusion: Family history of vitiligo is associated with an early onset of vitiligo. There is no correlation of family history with the type of vitiligo, stability of lesions, and areas involved. Severity is not associated with family history. Apart from other alleles, alleles A2, and B44 play a significant role in vitiligo in the Indian patients.

    Clinical prediction models are developed to calculate estimates of the probability of the presence/occurrence or future course of a particular prognostic or diagnostic outcome from multiple clinical or non-clinical parameters. Radiologic imaging techniques are being developed for accurate detection and early diagnosis of disease, which will eventually affect patient outcomes. Hence, results obtained by radiological means, especially diagnostic imaging, are frequently incorporated into a clinical prediction model as important predictive parameters, and the performance of the prediction model may improve in both diagnostic and prognostic settings. This article explains in a conceptual manner the overall process of developing and validating a clinical prediction model involving radiological parameters in relation to the study design and statistical methods. Collection of a raw dataset; selection of an appropriate statistical model; predictor selection; evaluation of model performance using a calibration plot, Hosmer-Lemeshow test and c-index; internal and external validation; comparison of different models using c-index, net reclassification improvement, and integrated discrimination improvement; and a method to create an easy-to-use prediction score system will be addressed. This article may serve as a practical methodological reference for clinical researchers.

  20. 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.

    Full Text Available Background: The intake of green tea has been increased recently due to its medicinal values. The antibacterial and antioxidant properties of green tea were found to be beneficial in the treatment of gingival and periodontal diseases. The aim of this comparative study was to compare the efficacy of the mouthwash containing green tea and chlorhexidine in the management of dental plaque-induced gingivitis. Materials and Methods: Thirty patients who participated in the study were divided randomly into two groups, each group of 15 patients was prescribed with either chlorhexidine or green tea mouthwash. Turesky modification of Quigley-Hein plaque index, Löe and Silness gingival index, Ainamo and Bay bleeding index, tooth stain, and tongue stain (TS were recorded at baseline, 15 days, and 1 month. The subjects were asked to report any discomfort or alteration in taste. Results: There was a significant decrease in plaque index, gingival index, and bleeding index in both the groups. However, green tea mouthwash resulted in a statistically significant decrease in bleeding index compared to chlorhexidine group. There was no significant difference in tooth stain and TS in both the groups. Conclusion: The green tea-containing mouthwash is equally effective in reducing the gingival inflammation and plaque to chlorhexidine.

    Full Text Available The present study was undertaken to determine and compare the efficacy of manual and powered toothbrushes under supervised and unsupervised conditions in 200 school-going children between 6 and 13 years of age. Two hundred school-going children aged between 6 and 13 years were selected. Children were randomly divided into two groups of 100 in each. Group 1 children were given manual brushes, while group 2 children were given powered brushes. The groups were further divided into two subgroups, with supervised brushing in subgroup A and unsupervised brushing in subgroup B. At 3, 6, 9 and 12 weeks, plaque was recorded according to Turseky-Gilmore-Glickman modification of Quingley Hein index and oral hygiene performance index. Data were statistically analyzed. Both brushes significantly reduced the plaque accumulation, though to different degrees. Powered brushes showed significant plaque reduction as compared to the manual brushes. Supervised group of both brushes showed a greater plaque reduction.

    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.

    Infarct size assessed by myocardial single-photon emission tomography (SPET) imaging is an important prognostic parameter after myocardial infarction (MI). We compared three commercially available automatic quantification algorithms that make use of normal templates for the evaluation of infarct extent and severity in a large population of patients with remote MI. We studied 100 consecutive patients (80 men, mean age 63{+-}11 years, mean LVEF 47%{+-}15%) with a remote MI who underwent resting technetium-99m tetrofosmin gated SPET study for infarct extent and severity quantification. The quantification algorithms used for comparison were a short-axis algorithm (Cedars-Emory quantitative analysis software, CEqual), a vertical long-axis algorithm (VLAX) and a three-dimensional fitting algorithm (Perfit). Semiquantitative visual infarct extent and severity assessment using a 20-segment model with a 5-point score and the relation of infarct extent and severity with rest LVEF determined by quantitative gated SPET (QGS) were used as standards to compare the different algorithms. Mean infarct extent was similar for visual analysis (30%{+-}21%) and the VLAX algorithm (25%{+-}17%), but CEqual (15%{+-}11%) and Perfit (5%{+-}6%) mean infarct extents were significantly lower compared with visual analysis and the VLAX algorithm. Moreover, infarct extent determined by Perfit was significantly lower than infarct extent determined by CEqual. Correlations between automatic and visual infarct extent and severity evaluations were moderate (r=0.47, P<0.0001 to r=0.62, P<0.0001) but comparable for all three algorithms. Correlations between LVEF and visual evaluation of infarct extent (r=-0.80, P<0.0001) and severity (r=-0.82, P<0.0001) were good but correlations were significantly lower for all three algorithms (r=-0.48, P<0.0001 to r=-0.65, P<0.0001). Systematically lower correlations were found in non-anterior infarctions (n=69) and obese patients (BMI {>=}30 kg/m{sup 2}, n=32

    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.

  15. 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

    Infectious keratitis after penetrating keratoplasty (PK) is a devastating condition that may result in graft failure and poor visual outcome. In this study, we retrospectively reviewed the medical records of patients who underwent PK between 2009 and 2014, and recorded those who developed infectious keratitis. We compared the predisposing factors and organisms isolated to those identified in our previous study, conducted between 1989 and 1994. The incidence of post-PK infectious keratitis decreased from 11.6% (41 out of 354 cases, 1989-1994) to 6.5% (9 out of 138 cases, 2009-2014). Graft epithelial defect and suture-related problems remained the leading two risk factors of infectious keratitis after PK. Gram-positive and Gram-negative bacterial infection decreased from 58.5% and 46.3% to 11.1% and 22.2%, respectively (P = 0.023 and P = 0.271). In contrast, fungus infection increased from 9.8% to 66.7% (P = 0.001) fungi have become the major pathogen for post-PK infectious keratitis. In conclusion, while the incidence of post-PK infectious keratitis has decreased over time, the number and frequency of fungal infections have significantly increased in the recent study period. Clinicians should be aware of the shifting trend in pathogens involved in post-PK infectious keratitis.

    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.

  1. 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.)

    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)

    The changes in the plasma level of PIVKA-II (Protein Induced by Vitamin K Absence or Antagonist-II) following the treatment or progress of the disease was studied in 60 patients with hepatocellular carcinoma. The positivity rate determined by the changes in PIVKA-II was 58.4 percent (35/60 cases) and was about the same as those reported so far, all of which were obtained by a single determination of PIVKA-II. Plasma PIVKA-II was elevated in 61.9 percent (13/21 cases) of alpha-fetoprotein negative patients and it was almost identical with the overall positivity rate. In parallel with serum alpha-fetoprotein, the plasma level of PIVKA-II was decreased after the surgery or transcatheter arterial embolization and was increased when the recurrence or progress of the disease was observed. Furthermore, the nonspecific elevation of PIVKA-II due to the associated liver cirrhosis or chronic hepatitis was infrequent compared with that of alpha-fetoprotein. In 18 cases positive with both PIVKA-II and alpha-fetoprotein, a close correlation (R = 0.91) was observed between the changes of these markers during the progress or treatment of the disease. Thus, it was suggested that determination of PIVKA-II in blood might be useful not only in the diagnosis but in monitoring the progress or the effectiveness of treatments in hepatocellular carcinoma.

    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.

Forty-one patients on long-term anticoagulation with acenocumarol without previous experience in self-monitoring participated to obtain 218 pairs of data. Several methods for comparative statistics were applied to assess the possible disagreements between techniques as well as a range of previously published criteria of clinical agreement and the very recently described error-grid for INR comparison that we partially modify. The mean age was 52.1 and the indications for oral anticoagulation were prosthetic valves (36.59%), atrial fibrillation (34.15%), venous thromboembolic disease (21.95%) and others (7.31%) with a target range of 2-3 INR units (63.4%) or 2.5-3.5 (36.6%). Analyzing the whole series of data, the Pearsons rho correlation coefficient for precision between methods was 0.95 and the C(b) bias correction factor for accuracy 0.99 with a minimal bias of 0.1 INR units between methods applying the Bland-Altman plot. The linear regression procedure described by Passing and Bablok showed a minimal deviation from the best-fit line and a slope of 0.90. The mean of the absolute relative differences was 7% which is in the "very good" range of agreement. No results were found in the clinically "dangerous" D zone of the error-grids with 99% of data in the clinically irrelevant and low relevant areas A and B. In this study self-management with the CoaguChek XS was clinically safe and reliable.

    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 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 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

    The safety and efficacy of nortriptyline and fluoxetine were compared in a double-blind, randomized, multicenter 5-week trial involving 205 outpatients with acute major depression of moderate severity. Seventy-two nortriptyline and 84 fluoxetine patients completed at least 2 weeks of medication and were included in the efficacy analysis; all patients were evaluated for side effects. Average total scores on the Hamilton Rating Scale for Depression (HAM-D) for both treatment groups declined from 22-23 at baseline to 11.5 at the conclusion of the 5-week period. At Week, 5, 71% of nortriptyline patients and 65% of fluoxetine patients were much or very much improved. Fluoxetine was associated more frequently with nausea (p less than .05), while nortriptyline was associated more frequently with dry mouth (p less than .05). These results are discussed in the context of selecting between nortriptyline and fluoxetine for a particular depressed patient. PMID:2050651

    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.

    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. It can be concluded that Jaladhara gave better relief in panic attack and phobic disorder while Sankhapuspi Rasayana is more useful in generalized anxiety disorder. Results of the study are encouraging and these two therapies i.e. Jaladhara and Sankhapuspi Rasayana may become first line treatment of Chittodvega (Anxiety disorders.

    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.

    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.

    2011-02-01

    Full Text Available Abstract Background It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called Norwegian Feral Sheep, normally distributed on coastal areas where ticks are abundant, is more protected against tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The aim of the present study was to test this hypothesis in an experimental infection study. Methods Five-months-old lambs of two Norwegian sheep breeds, Norwegian White (NW sheep and Old Norse (ON sheep, were experimentally infected with a 16S rRNA genetic variant of Anaplasma phagocytophilum (similar to GenBank accession number M73220. The experiment was repeated for two subsequent years, 2008 and 2009, with the use of 16 lambs of each breed annually. Ten lambs of each breed were inoculated intravenously each year with 0.4 ml A. phagocytophilum-infected blood containing approximately 0.5 × 106 infected neutrophils/ml. Six lambs of each breed were used as uninfected controls. Half of the primary inoculated lambs in each breed were re-challenged with the same infectious dose at nine (2008 and twelve (2009 weeks after the first challenge. The clinical, haematological and serological responses to A. phagocytophilum infection were compared in the two sheep breeds. Results The present study indicates a difference in fever response and infection rate between breeds of Norwegian sheep after experimental infection with A. phagocytophilum. Conclusion Although clinical response seems to be less in ON-lambs compared to NW-lambs, further studies including more animals are needed to evaluate if the ON-breed is more protected against tick-borne infections than other Norwegian breeds.

    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

    Dental clinicians have an expanding range of biomaterial choices for restoring tooth structure. Scientific developments in cariology, advances in dental biomaterials, and patients' esthetic concerns have led to a reduction in amalgam restorations and an increase in composite restorations. The aim of this study was to compare teaching time with students' clinical procedures in amalgam and composite posterior restorations in dental schools across the United States. Academic deans in 60 schools were invited to complete a survey that asked for the amount of instructional time for amalgam and composite posterior restorations and the number of clinical restorations performed by their Classes of 2009, 2010, and 2011. Of these 60, 12 returned surveys with complete data, for a 20% response rate. Responses from these schools showed little change in lecture and preclinical laboratory instruction from 2009 to 2011. There was a slight increase in two-surface restorations for both amalgam and composites; however, the total number of reported composite and amalgam restorations remained the same. Of 204,864 restorations reported, 53% were composite, and 47% were amalgam. There were twice as many multisurface large or complex amalgam restorations as composites. One-surface composite restorations exceeded amalgams. Among the participating schools, there was little to no change between curriculum time and clinical procedures. Findings from this preliminary study reflect a modest increase in two-surface resin-based restorations placed by dental students from 2009 to 2011 and little change in curricular time devoted to teaching amalgam restorations. The total number of posterior composite restorations placed by students in these schools was slightly higher than amalgams.

    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.

    Full Text Available ABSTRACT: BACKGROUND: The emergence of multidrug resistant (MDR microor ganism infections has generated considerable attention in the recent past . The primary goal of infection control procedures is to prevent cross contamination betwee n patients as well as between patients and health care providers. This can be achieved by the safe disposal of body fluids and cultures having such microorganisms from the hospital ward and labo ratory. This study aimed at comparing the efficacy of comme rcially available disinfectants on microorganisms isolated from clinical samples. MATERIAL AND METHOD: Four commonly used disinfectants namely Savlon, 70% Ethanol, Dettol an d Lysol were tested for their Antibacterial and Anti fungal effects against multidrug resistant bac teria and fungi isolated from clinical samples from inpatients admitted to Sri Siddhartha Medical Colle ge Hospital, Tumkur. Multi- drug resistant (MDR microorganisms E. coli, S. aureus, K. pneumoniae, P . aeruginosa, C. albicans, A. niger and A flavus isolated from clinical samples were used for testin g the effectiveness of disinfectants. Agar Well- diffusion method using Mueller Hinton Agar and Modi fied Muller Hinton agar was used to assess the effectiveness of disinfectants. Phenol was consider ed to be the standard disinfectant to which other disinfectants were compared. The zone of inhibitio n (ZOI for each isolate was measured. These were compared to the ZOI of Phenol (40mm. The resu lts were statistically analyzed by descriptive statistical methods. RESULTS: The ZOI against S. aureus and E. coli of Savlon was 33mm & 34mm and for Dettol 38mm & 37mm, respectively. But for K . pneumoniae the ZOI was 29mm & 30mm and for P. aeruginosa was 24mm and 30mm for Savlon and Dettol, respectively. The ZOI for 70% ethanol ranged from 32mm to 34 mm on all the isolates. The ZOI for Lysol ranged from 22mm to 24mm on isolates. CONCLUSION: The disinfectants -- Savlon and Dettol can be used as

    Patients with combined membranous nephropathy (MN) and focal segmental glomerulosclerosis (FSGS) have been reported with different clinical significance. Investigations on the possible mechanisms of the combined glomerular lesions are necessary but scarce. Twenty patients with both MN and FSGS lesions were enrolled in the study. Sixty-five patients with primary MN and 56 patients with primary FSGS were used as disease controls. Clinical data on renal biopsy and during follow-up were collected. Circulating anti-phospholipase A2 receptor (PLA2R) antibody, glomerular PLA2R expression, IgG4 deposition, and soluble urokinase receptor (suPAR) levels were detected. We found that patients with combined lesions presented with older age, less proteinuria, higher albumin, and better renal function on biopsy. These were comparable to the patients with primary MN, but differed from the patients with primary FSGS. Patients with combined lesions showed higher stages of MN, no cellular variant on FSGS classification, and more common (100.0%) tubulointerstitial injury than both primary MN and primary FSGS patients. In the patients with combined lesions, 80.0% had circulating anti-PLA2R antibody and 68.4% had IgG4 predominant deposition in glomeruli, which were comparable to primary MN. The patients with combined lesions had significantly lower urinary suPAR concentrations, than the primary FSGS patients (315.6 ± 151.0 vs 752.1 ± 633.9 pg/μmol; P = 0.002), but similar to the primary MN patients (267.9 ± 147.5 pg/μmol). We conclude that patients with combined MN and FSGS may share the same underlying pathogenesis with primary MN. The FSGS lesion might be secondary to primary MN.

    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.

    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.

In this study, 60 participants with self-reported knee discomfort were randomized into two groups receiving CFB or placebo. Initial levels of knee discomfort were evaluated by Western Ontario and McMaster Universities Arthritis Index (WOMAC and McGill Pain Questionnaire (MPQ scores at the beginning of the study and also at 7 and 14 days after treatment. Results showed that supplementation with CFB significantly improved knee discomfort in the study subjects; significant reductions of mean within-subject change in WOMAC and MPQ scores were observed for the CFB group compared to the placebo group at both 7 and 14 days after treatment. Estimated treatment differences for the MPQ score were -5.8 (P=0.0009 and -8.9 (P<0.0001 at Day 7 and 14, respectively. Estimated differences for the WOMAC score were -5.3 (P=0.06 and -13.73 (P<0.0001 at Day 7 and 14, respectively. Negative values indicate greater reductions in reported discomfort. On both Day 7 and Day 14, the trend was toward greater improvement in the CFB group. The placebo group did not exhibit any change in the WOMAC and MPQ scores. In conclusion, supplementation with 110 mg CFB twice per day was associated with improving knee discomfort during the 2 weeks of intake.Keywords: CFB, joint discomfort, WOMAC score, McGill pain score

    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.

    Since the drop in the bed capacity of civil psychiatric hospitals, an increase in the bed capacity of forensic psychiatric care and prison units has been reported in the United States and Europe. However, in Canada, a decrease in the number of people with severe mental illness (SMI) during the last two decades in penitentiaries has been reported. At the same time, an increase in individuals found not criminally responsible on account of mental disorder (NCRMD) was observed in forensic hospitals. The aim of this study is to compare incarcerated severely mentally ill (I-SMI) individuals with forensic-hospitalized SMI individuals in terms of their clinical profiles and service use in the province of Quebec (Canada). A case-control study design was selected using a sample of 44 I-SMI individuals and 59 forensic-hospitalized SMI individuals. Important findings include the following: I-SMI persons had less schooling; they more often reported suicide attempts and violent and non-violent crimes; and they had a higher level of comorbidity involving Cluster B personality disorders and substance-use disorders. Forensic-hospitalized SMI persons were more likely to have been receiving psychiatric follow-up before hospitalization. The final logistic regression model showed that lifetime suicide attempts, non-violent crimes, and psychopathic traits were higher among I-SMI individuals than among forensic-hospitalized SMI individuals. In contrast, receiving regular psychiatric follow-up was associated with forensic-hospitalized SMI individuals. Differences in psychopathological characteristics and the use of mental health services were found for I-SMI persons. More research is needed to determine which new initiatives might be efficacious in addressing the mental health needs of I-SMI individuals.

    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.

    Recently, photodynamic therapy (PDT) has been suggested as a new treatment option that is free from side effects for erosive-atrophic oral lichen planus (OLP). The purpose of this study was to compare the effect of toluidine blue-mediated photodynamic therapy (TB-PDT) with local corticosteroids on treatment of erosive-atrophic OLP. In this randomized clinical trial, 25 patients with keratotic-atrophic-erosive oral lichen planus were allocated randomly into two groups. Group 1 (experimental): topical application of toluidine blue with micropipette was applied, and after 10 min, the patients were treated with a 630-nm GaAlAs laser (power density: 10 mW/cm(2)) during two visits. Group 2 (control) used mouthwash diluted with dexamethasone (tab 0/5 in 5 ml water) for 5 min, and then, it was spat out, and after 30 min, the mouth was rinsed with 30 drops of nystatin 100,000 units for 5 min and again spat out. Demographic data, type, and severity of the lesions and pain were recorded before and after treatment and then at the 1-month follow-up visit. Response rate was defined based on changes in intensity of the lesions and pain. In the experimental and control groups, sign scores of changes significantly reduced after treatment respectively (p = 0.021) and (p = 0.002), but between the two groups, no significant difference was observed (p = 0.72). In the experimental (p = 0.005) and control groups (p = 0.001), the intensity of lesions significantly reduced after treatment and there was a significant difference between the two groups (p = 0.001). The mean amount of improvement in pain was significantly greater in the control group compared with the experimental group (p < 0.001) (α = 0.05). Our study showed that TB-PDT with laser was effective in the management of OLP.

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.

    This study examined the biological and clinical significance of NAC1 (nucleus accumbens associated 1) expression in both cervical squamous cell carcinomas and adenocarcinomas/adenosquamous carcinomas. Using immunohistochemistry, the frequency of positive NAC1 expression in adenocarcinomas/adenosquamous carcinomas (31.0%; 18/58) was significantly higher than that in squamous cell carcinomas (16.2%; 12/74) (P = .043). NAC1 gene amplification was identified by fluorescence in situ hybridization in 5 (7.2%) of 69 squamous cell carcinomas. NAC1 amplification was not identified in the adenocarcinomas (0%; 0/58). Positive NAC1 expression was significantly correlated with shorter overall survival in squamous cell carcinomas (P NAC1 expression in squamous cell carcinomas was an independent prognostic factor for overall survival after standard radiotherapy (P = .0003). In contrast to squamous cell carcinomas, positive NAC1 expression did not correlate with shorter overall survival in adenocarcinomas/adenosquamous carcinomas (P = .317). Profound growth inhibition, increased apoptosis, decreased cell proliferation, and decreased cell migration and invasion were observed in silencing RNA-treated cancer cells with NAC1 overexpression compared with cancer cells without NAC1 expression. NAC1 overexpression stimulated proliferation, migration, and invasion in the cervical cancer cell lines TCS and Hela P3, which normally lack NAC1 expression. These findings indicate that NAC1 overexpression is critical to the growth and survival of cervical carcinomas irrespective of histologic type. Furthermore, they suggest that NAC1 silencing RNA-induced phenotypes depend on the expression status of the targeted cell line. Therefore, cervical carcinoma patients with NAC1 expression may benefit from a targeted therapy irrespective of histologic type.

    Full Text Available Aims: To investigate clinically and radiographically, the bone fill in extraction sockets using demineralized freeze-dried bone allograft alone and along with platelet-rich fibrin (PRF. Materials and Methods: A randomized controlled clinical trial was carried out on 36 nonrestorable single-rooted teeth sites. Sites were randomized into demineralized freeze-dried bone allograft (DFDBA combined with PRF - test and DFDBA - control groups using a coin toss method. After the placement of graft material, collagen membrane was used to cover it. The clinical parameters recorded were ridge width and ridge height. All the parameters were recorded at baseline and at 90 and 180 days. Statistical Analysis Used: Independent t-test and paired t-test. Results: In both groups, there is significant reduction in loss of ridge width and ridge height from baseline to 90 days (P < 0.001, baseline to 180 days (P < 0.001, and 90-180 days (P < 0.001. However, when both the groups were compared the test group favored in the reduction of ridge width while there was no statistical difference in reduction of ridge height among at different intervals. Conclusions: Although DFDBA is considered as an ideal graft material, PRF can be used as an adjunctive with DFDBA for socket preservation.

    Cytogenetic methods, including G-banded chromosome analysis and fluorescence in situ hybridization (FISH) analysis, serve as a critical part of routine clinical testing for hematological malignancies and provide important diagnostic and prognostic information; however, the limitations of cytogenetic methods, including the requirement for actively dividing cells and lower resolution of G-banded chromosome analysis as well as the inability of both G-banded chromosome analysis and FISH to detect copy number neutral loss of heterozygosity (CN-LOH), can result in a failure to detect genomic abnormalities with diagnostic and prognostic significance. Here, we compared the abnormality detection rate of clinically requested testing (i.e., G-banded chromosome analysis and FISH) with high-resolution oligo (i.e., array comparative genomic hybridization (aCGH)) and single-nucleotide polymorphism (SNP)/oligo hybrid (i.e., SNP-CGH) arrays in a series of patients, in an effort to assess the ability of newer technologies to overcome these limitations. This series found the detection rate for SNP-CGH to be 62.5% for myelodysplastic syndrome (MDS) cases and 72.7% for chronic lymphocytic leukemia (CLL) cases, which are significantly higher than the detection rates of aCGH (31.3% for MDS and 54.5% for CLL) and G-banding and/or FISH (43.8% for MDS and 54.5% for CLL). This demonstrates the advantages of combining SNP-CGH with conventional cytogenetics to provide comprehensive clinical information by detecting clonality, large balanced rearrangements, copy number aberrations, and CN-LOH.

    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.

    Full Text Available BACKGROUND: Both brucellosis and tuberculosis are chronic-debilitating systemic granulomatous diseases with a high incidence in many countries in Africa, Central and South America, the Middle East and the Indian subcontinent. Certain focal complications of brucellosis and extrapulmonary tuberculosis are very difficult to differentiate clinically, biologically and radiologically. As the conventional microbiological methods for the diagnosis of the two diseases have many limitations, as well as being time-consuming, multiplex real time PCR (M RT-PCR could be a promising and practical approach to hasten the differential diagnosis and improve prognosis. METHODOLOGY/PRINCIPAL FINDINGS: We designed a SYBR Green single-tube multiplex real-time PCR protocol targeting bcsp31 and the IS711 sequence detecting all pathogenic species and biovars of Brucella genus, the IS6110 sequence detecting Mycobacterium genus, and the intergenic region senX3-regX3 specifically detecting Mycobacterium tuberculosis complex. The diagnostic yield of the M RT-PCR with the three pairs of resultant amplicons was then analyzed in 91 clinical samples corresponding to 30 patients with focal complications of brucellosis, 24 patients with extrapulmonary tuberculosis, and 36 patients (Control Group with different infectious, autoimmune or neoplastic diseases. Thirty-five patients had vertebral osteomyelitis, 21 subacute or chronic meningitis or meningoencephalitis, 13 liver or splenic abscess, eight orchiepididymitis, seven subacute or chronic arthritis, and the remaining seven samples were from different locations. Of the three pairs of amplicons (senX3-regX3+ bcsp3, senX3-regX3+ IS711 and IS6110+ IS711 only senX3-regX3+ IS711 was 100% specific for both the Brucella genus and M. tuberculosis complex. For all the clinical samples studied, the overall sensitivity, specificity, and positive and negative predictive values of the M RT-PCR assay were 89.1%, 100%, 85.7% and 100

  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)

    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.

    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

  15. 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)

    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.

    Radiation treatment planning for women with locally advanced cervical cancer (stages IB2-IVA) is often based on positron emission tomography (PET). PET, however, has poor sensitivity in detecting metastases in aortocaval nodes. We have initiated a study with the objective of determining whether pre-therapeutic laparoscopic surgical staging followed by tailored chemoradiation improves survival as compared with PET/computed tomography (CT) radiologic staging alone followed by chemoradiation. This international, multicenter phase III trial will enroll 600 women with stages IB2-IVA cervical cancer and PET/CT findings showing fluorodeoxyglucose-avid pelvic nodes and fluorodeoxyglucose-negative para-aortic nodes. Eligible patients will be randomized to undergo either pelvic radiotherapy with chemotherapy (standard-of-care arm) or surgical staging via a minimally invasive extraperitoneal approach followed by tailored radiotherapy with chemotherapy (experimental arm). The primary end point is overall survival. Secondary end points are disease-free survival, short- and long-term morbidity with pre-therapeutic surgical staging, and determination of anatomic locations of metastatic para-aortic nodes in relationship to the inferior mesenteric artery. We believe this study will show that tailored chemoradiation after pre-therapeutic surgical staging improves survival as compared with chemoradiation based on PET/CT in women with stages IB2-IVA cervical cancer.

    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.

    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.

    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

    Full Text Available Background and Aims: Video laryngoscopy has been recommended as an alternative during difficult conventional direct laryngoscopy using the Macintosh blade (MAC. However, successful visualisation of the larynx and tracheal intubation using some of the indirect laryngoscopes or video laryngoscopes (VL requires hand-eye coordination. We conducted this study to determine whether non-channel VLs are easy to use for novices and whether there is any association between expertise with MAC and ease of tracheal intubation with VLs. Methods: Anaesthesiologists participating in the study were divided into three groups: Group novice to intubation (NTI, Group novice to videoscope (NVL- experienced with MAC, novice to VLs and Group expert (EXP experienced in all. Group NTI, NVL received prior mannequin training. VLs- Truview ® and McGrath series 5 (MGR were compared with MAC. One hundred and twenty six adult patients with normal airway were randomised to both, the intubating anaesthesiologist and laryngoscope. 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.

    The aim of this investigation was to test for the scintigraphic detection of metastases of malignant melanoma with a new radiopharmaceutical, 99Tcm-glutathione (99Tcm-GSH), in comparison with 99Tcm-anti-melanoma antibody (99Tcm-AMAb). Glutathione was labelled with 99Tcm by a Sn2+ reduction method with an efficiency of > 99% as determined by instant thin layer chromatography (ITLC). Anti-melanoma antibody was obtained as a kit from SORIN (Italy) and labelled with 99TcmO-4. Forty-three patients with a total of 55 biopsy-proven metastatic melanoma foci, 1 ocular melanoma and 20 benign pathologic foci, also confirmed by ultrasound, computed tomography and magnetic resonance imaging, were included in the study after giving their informed consent. Following the intravenous (i.v.) injection of 500 MBq 99Tcm-AMAb, scintigraphic images of the involved areas were obtained 6 h post-injection. Three days later, the same patients were given 500 MBq 99Tcm-GSH i.v. and images were obtained 6 and 24 h post-injection. The images were classified as positive (focal abnormal accumulation) or negative. Quantitative evaluation was also applied. Regions of interest were drawn over the involved areas and nearby soft tissues and the target-to-nontarget (T/NT) ratios obtained with 99Tcm-AMAb (T/NT: 1.92 +/- 0.2) and 99Tcm-GSH (T/NT: 1.84 +/- 0.2) were compared (0.1 < P < or = 0.3). The sensitivity (and specificity) of 99Tcm-AMAb and 99Tcm-GSH in the detection of malignant melanoma metastases were 91% (95%) and 84% (90%), respectively. Compared with 99Tcm-AMAb, the advantages of 99Tcm-GSH are lower levels of blood radioactivity, lower costs and easy in-house preparation. In conclusion, our results show that 99Tcm-GSH is a potentially useful radiopharmaceutical for the detection of metastases of malignant melanoma.

    Explanations of adult involvement in sex work typically adopt one of two approaches. One perspective highlights a variety of negative experiences in childhood and adolescence, including physical and sexual abuse, family instability, poverty, associations with "pimps" and other exploiters, homelessness, and drug use. An alternative account recognizes that some of these factors may be involved, but underscores the contribution of more immediate circumstances, such as current economic needs, human capital, and employment opportunities. Prior research offers a limited assessment of these contrasting claims: most studies have focused exclusively on people working in the sex industry and they have not assessed the independent effects of life course variables central to these two perspectives. We add to this literature with an analysis that drew on insights from life course and life-span development theories and considered the contributions of factors from childhood, adolescence, and adulthood. Our comparative approach examined predictors of employment in sex work relative to two other low-income service or care work occupations: food and beverage serving and barbering and hairstyling. Using data from a study of almost 600 workers from two cities, one in Canada and the other in the United States, we found that both immediate circumstances and negative experiences from early life are related to current sex work involvement: childhood poverty, abuse, and family instability were independently associated with adult sex work, as were limited education and employment experience, adult drug use, and marital status.

    Full Text Available Background: Doctor’s prescription provides vivid information and instruction to the patient. In spite of the WHO programs, irrational prescribing is still a common practice. Aim: To evaluate and compare the prescribing pattern of private practitioners and physicians of a tertiary care teaching hospital in a semi urban area and detect their rationality. Materials & methods: 150 prescriptions, each prescribed by private practitioners and physicians of a tertiary care hospital were collected over a period of two months and evaluated. Information regarding the drugs used, drugs from the essential drug list, the use of injections, fixed dose combinations, drug prescribed by generic names were observed. Results: The average number of drugs per prescription prescribed by the private practitioners was 2.47 compared to 1.58 by the physicians of a tertiary care hospital. 82% of prescriptions of private practitioners had one injection prescribed in the prescription compared to 12% by physicians of a tertiary care hospital. 30 unnecessary drugs, 46 unnecessary injections and 8 irrational fixed dose combinations were prescribed by the private practitioners, whereas only 6 unnecessary drugs and 2 unnecessary injections were prescribed by the physicians of a tertiary care hospital respectively. There was no irrational fixed dose combination prescribed by them. The private practitioners prescribed 12 (3.2% drugs by generic names, whereas the physicians of a tertiary care hospital prescribed 72 (30.3% drugs by generic names. (P<0.000. 36 (9.7% drugs prescribed by the private practitioners were not included in the essential drug list and only 2 (0.8% drugs prescribed by the physicians of a tertiary care hospital were not included in the essential drug list. Conclusion: Private practitioners prescribe more irrational prescriptions on comparison with the physicians of a tertiary care teaching hospital. This may be due to the promotional pharmaceutical incentives

    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.

  11. 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.

    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.

    Full Text Available AIM OF THE STUDY: To ascertain efficacy of the Circle absorption system and the Bain breathing system in maintaining effective hypocapnia to create a favorable environment for smooth conduct of intracranial surgery, with the help of Capnographic monitoring. 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. CONCLUSION: It can be concluded that apart from the variation of fresh gas flow required in each system and the rebreathing

    2016-01-01

    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

    AIM: This study aimed to verify the influence of oral environment and denture cleansers on the surface roughness and hardness of two different denture base materials. METHODS: A total of sixteen identical removable disc specimens (RDS) were processed. Eight RDS were made from heat-cured acrylic resin (AR) and the other eight were fabricated from thermoplastic injection moulded resin (TR). Surface roughness and hardness of DRS were measured using ultrasonic profilometry and Universal testing machine respectively. Then the four RDS (two AR and two of TR) were fixed to each maxillary denture, after three months RDS were retrieved. Surface roughness and hardness of RDS have measured again. RESULTS: The surface roughness measurements revealed no significant difference (p >0.05) for both disc groups at baseline. However, both groups showed a significant increase in the surface roughness after three months with higher mean value for (TR) group. On the other hand, the (AR) group showed higher hardness mean value than (TR) group at baseline with no significant decrease in the hardness values (p >0.05) following three months follow-up period. CONCLUSIONS: Denture cleansers have an effect on the denture’s surface roughness and hardness concurrently with an oral condition which will consequently influence the complete dentures’ lifetime and patients’ satisfaction.

    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.

    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.

    Methods for determining sample size and power when comparing two groups in clinical trials are widely available. Studies comparing three or more treatments are not uncommon but are more difficult to analyse. A linear nomogram was devised to help calculate the sample size required when comparing up to five parallel groups. It may also be used retrospectively to determine the power of a study of given sample size. In two worked examples the nomogram was efficient. Although the nomogram offers o...

    Full Text Available Corporate governance is a key element of today’s economic reality being more and more present in many countries around the world. This paper has two main objectives. The first one is to offer more insight into the concept of corporate governance by a thorough literature review and by presenting and analyzing a framework of corporate governance. The second objective of this paper is to investigate the corporate governance situation in three developing economies (Romania, Bulgaria and Hungary. 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 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

    2010-08-01

    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 Abstract Background Being severely overweight is a distinctive clinical feature of Prader-Willi Syndrome (PWS. PWS is a complex multisystem disorder, representing the most common form of genetic obesity. The aim of this study was the analysis of the gait pattern of adult subjects with PWS by using three-Dimensional Gait Analysis. The results were compared with those obtained in a group of obese patients and in a group of healthy subjects. Methods Cross-sectional, comparative study: 19 patients with PWS (11 males and 8 females, age: 18–40 years, BMI: 29.3–50.3 kg/m2; 14 obese matched patients (5 males and 9 females, age: 18–40 years, BMI: 34.3–45.2 kg/m2; 20 healthy subjects (10 males and 10 females, age: 21–41 years, BMI: 19.3–25.4 kg/m2. Kinematic and kinetic parameters during walking were assessed by an optoelectronic system and two force platforms. Results PWS adult patients walked slower, had a shorter stride length, a lower cadence and a longer stance phase compared with both matched obese, and healthy subjects. Obese matched patients showed spatio-temporal parameters significantly different from healthy subjects. Furthermore, Range Of Motion (ROM at knee and ankle, and plantaflexor activity of PWS patients were significantly different between obese and healthy subjects. Obese subjects revealed kinematic and kinetic data similar to healthy subjects. Conclusion PWS subjects had a gait pattern significantly different from obese patients. Despite that, both groups had a similar BMI. We suggest that PWS gait abnormalities may be related to abnormalities in the development of motor skills in childhood, due to precocious obesity. A tailored rehabilitation program in early childhood of PWS patients could prevent gait pattern changes.

    Women and men differ in a wide variety of behavioral traits and in their vulnerability to developing certain mental disorders. This review endeavors to explore how recent preclinical and clinical research findings have enhanced our understanding of the factors that underlie these disparities. We start with a brief overview of some of the important genetic, molecular, and hormonal determinants that contribute to the process of sexual differentiation. We then discuss the importance of animal models in studying the mechanisms responsible for sex differences in neuropsychiatric disorders (e.g., drug dependence) - with a special emphasis on experimental models based on the neurodevelopmental and "three hits" hypotheses. Next, we describe the most common brain phenotypes observed in vivo with magnetic resonance imaging. We discuss the challenges in interpreting these phenotypes vis-à-vis the underlying neurobiology and revisit the known sex differences in brain structure from birth, through adolescence, and into adulthood. This is followed by a presentation of pertinent clinical and epidemiological data that point to important sex differences in the prevalence, course, and expression of psychopathologies such as schizophrenia, and mood disorders including major depression and posttraumatic stress disorder. Recent evidence implies that mood disorders and psychosis share some common genetic predispositions and neurobiological bases. Therefore, modern research is emphasizing dimensional representation of mental disorders and conceptualization of schizophrenia and major depression as a continuum of cognitive deficits and neurobiological abnormalities. Herein, we examine available evidence on cerebral sexual dimorphism to verify if sex differences vary quantitatively and/or qualitatively along the psychoses-depression continuum. Finally, sex differences in the prevalence of posttraumatic disorder and drug abuse have been described, and we consider the genomic and molecular

    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.

  3. 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 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.

    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 An ectopic pregnancy is one in which fertilized ovum is implanted at the site other than normal uterine cavity.[1] Incidence of ectopic pregnancy is 1:160 deliveries.[2] Clinical presentation is variable from acute to chronic type. Due to its varied clinical presentation ectopic pregnancy poses great diagnostic difficulty both to obstetrician, physician and surgeons.[3] OBJECTIVE: To find out incidence in our study population and to evaluate symptomatically and clinical presentation in these patients. MATERIALS AND METHODS: Retrospective study of 34 ectopic pregnancies admitted and treated in Medical College hospital, Ujjain from 2010 to 2015 are included in the study. RESULTS: The incidence of ectopic pregnancy is more between the age group of 21-30years (73.52% and in Multigravida 64.71%. Infertility and previous tubal surgery are the high risk factors for tubal pregnancy. Pain in abdomen was present in all 34 cases, amenorrhea in 97.05% and bleeding per vagina in 76.47% cases. Syncopal attacks, vomiting were detected in 14.70% cases. Acute ectopic pregnancy was detected in 14.71% and chronic in 85.29% cases. 82.35% cases presented with adnexal mass, 79.41% with cervical motion tenderness, 50% with pallor, 32.35% with abdominal lump and tenderness and 11.76% with fullness in POD. CONCLUSION: Ectopic pregnancy is leading cause of maternal mortality in first trimester. In spite of advanced diagnostic techniques. It poses great diagnostic difficulties due to varied signs and symptoms. Previous tubal surgery pelvic inflammatory disease and infertility are the risk factors of tubal pregnancy.

    Full Text Available Ayurvedic literature introduced several substitutes for the herbs which are either not available or which are not accessible for various reasons. On review of more than 35 texts and their commentaries it is found that there are more than 350 substitutes in the Ayurvedic texts from ancient to modern times. Kustha is known to therapeutics since Vedic period (2000 BC. Puskaramula and Erandamula were introduced to Ayurvedic Materia Medica by Agnivesa (500 BC. While mentioning the substitutes of Pushkaramula, Yogaratnakara quoted Kushta and Erandamula as the substitutes. Earlier author studied the pharmacognostical similarities between the three plants. Therefore, in the present study it iss decided to conduct a comparative study using the root powders of these three herbs in subjects (n=90 suffering with Tamaka Swasa (Bronchial Asthma divided into three groups. The results are suggestive that all the trial herbs have comparable therapeutic benefits in the subjects of Tamaka Swasa. While Kustha and Puskaramula have chemical as well as therapeutic similarity, Erandamula and pushkaramula shared only therapeutic similarity though chemically dissimilar. Thiss paper emphasizes the need for the identification of cost effective substitutes basing on the text in place of endangered or extinct medicinal plants.

    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.

    Full Text Available OBJECTIVE: Mixed episodes have been described as more severe than manic episodes, especially due to their longer duration and their association with higher rates of suicide attempts, hospitalization and psychotic symptoms. The purpose of this study was to compare the severity between mixed and pure manic episodes according to DSM-IV criteria, through the evaluation of sociodemographic data and clinical characteristics. METHOD: Twenty-nine bipolar I patients presenting acute mixed episodes were compared to 20 bipolar I patients with acute manic episodes according to DSM-IV criteria. We analyzed (cross-sectionally episode length, presence of psychotic symptoms, frequency of suicide attempts and hospitalization, Young Mania Rating Scale scores, Hamilton Depression Rating Scale scores and the Clinical Global Assessment Scale scores. RESULTS: Young Mania Rating Scale scores were higher in manic episodes than in mixed episodes. There were no differences in gender frequency, CGI scores and rates of hospitalization, suicide attempts and psychotic symptoms, when mixed and manic episodes where compared. Patients with mixed episodes were younger. CONCLUSION: In our sample, mixed states occurred at an earlier age than manic episodes. Contrary to previous reports, we did not find significant differences between manic and mixed episodes regarding severity of symptomatology, except for manic symptoms ratings, which were higher in acute manic patients. In part, this may be explained by the different criteria adopted on previous studies.OBJETIVO: Estados mistos têm sido descritos como mais graves que episódios de mania, especialmente pela maior duração dos episódios, maiores taxas de suicídio, hospitalização e sintomas psicóticos. O objetivo deste estudo foi comparar a severidade entre episódios mistos e mania pura definidos segundo critérios do DSM-IV, avaliando-se características clínicas e sociodemográficas dos pacientes.

    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

    2011-06-01

    With the ongoing debate over health care reform in the United States, public health and policy makers have paid growing attention to the need for comparative effectiveness research (CER). Recent allocation of federal funds for CER represents a significant move toward increased evidence-based practice and better-informed allocation of constrained health care resources; however, there is also heated debate on how, or whether, CER may contribute to controlling national health care expenditures. Economic evaluation, in the form of cost-effectiveness or cost-benefit analysis, is often an aspect of CER studies, yet there are no recommendations or guidelines for providing clinical investigators with the necessary skills to collect, analyze, and interpret economic data from clinical trials or observational studies. With an emphasis on multidisciplinary research, the Clinical and Translational Science Award (CTSA) consortium and institutional CTSA sites serve as an important resource for training researchers to engage in CER. In this article, the authors discuss the potential role of CTSA sites in integrating economic evaluation methods into their comparative effectiveness education goals, using the Columbia University Medical Center CTSA as an example. By allowing current and future generations of clinical investigators to become fully engaged not only in CER but also in the economic evaluations that result from such analyses, CTSA sites can help develop the necessary foundation for advancing research to guide clinical decision making and efficient use of limited resources.

    1992-01-01

    Ectopic pregnancy remains a leading cause of maternal mortality and accounts for a sizeable proportion of infertility and ectopic recurrence. The possibility that a woman is experiencing an ectopic pregnancy must be considered when evaluating a woman, especially a sterilized woman, who has a possible pregnancy, amenorrhea, abdominal pain, or abnormal bleeding; studies have found that one in six pregnancies occurring after tubal sterilization are ectopic. The authors present a clinical study of 82 cases of ectopic pregnancy admitted to the department of Obstetrics and Gynecology of Mahatma Gandhi Institute of Medical Sciences, Sevagram. Cases of ectopic pregnancy represent 0.99% of total obstetric admissions, of whom 69.51% were diagnosed as such on admission. 40.24% of the women were older than 30 years, while 34.14% were elderly beyond third parity. 70.73% of the women presented before missing their second period. Patients presented with multiple complaints, but the most common was abdominal pain reported by 61.70%. 78.04% were admitted with an acute abdomen, but shock was present in only 7.14% of cases. The main surgical treatment modality was salpingectomy among 59.75%. There was no maternal mortality through postoperative morbidity in the form of paralytic ileus, although fever did occur in some women.

    Maximov, Ivan I; Neuner, Irene; Shah, N Jon

    2015-01-01

    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...

  11. Cryogenic Thermophysical Studies for Clinical Medicine

    Institute of Scientific and Technical Information of China (English)

    华泽钊

    2002-01-01

    Cryogenic technology has been widely used in clinical medicine and in pharmaceutics, so thermophysical studies are extremely important to solve problems during freezing and thawing. This paper reports some recent research in clinical medicine, including cryo-injury, cryosurgery, and cryopreservation of some important cells and tissues. Microscopic images of the freezing process with a cryomicroscope system show that the dendritic ice growth is affected by the solution concentration, the cooling rate, and the number of embryos. An enthalpy method is used for the freeze-thaw analysis of the cryosurgery with a program developed to predict the temperature profile and the interface motion, which compares well with experimental results. A very rapid cooling technique is developed by quenching the samples into subcooled liquid nitrogen for vitrification of cells and tissues. An analytical method developed to prevent the fracture of arteries during freezing has been verified by the electronic microscopic investigation.

    2008-01-01

    The preoperative assessment clinic (PAC) has been implemented in most major hospitals. However, there is no uniformity in the way PACs are organised. We compared the organisational structure of the PACs from all eight university hospitals in The Netherlands, looking at the following variables: number of patients visiting the PAC, staffing of the PAC, opening hours, scheduling, and additional preoperative diagnostic testing. The number of patients seen yearly varies from 7.000 to 13.500. In all clinics, the preoperative assessment was performed by anaesthetists and residents. In five PACs, preoperative assessment was also performed by physician assistants or nurse practitioners. Opening hours varied. Consultations are by appointment, 'walk-in', or a combination of these two. In four clinics additional testing is performed at the PAC itself. This study shows that the organisational structure of the PAC at similar university hospitals varies greatly; this can have important implications when designing a benchmarking process.

  4. Three different surgical techniques of crown lengthening: A comparative study

    Directory of Open Access Journals (Sweden)

    Ramya Nethravathy

    2013-01-01

    Full Text Available Introduction: A short clinical crown may lead to poor retention form thereby leading to improper tooth preparation. Surgical crown lengthening procedure is done to increase the clinical crown length without violating the biologic width. Several techniques have been proposed for clinical crown lengthening which includes gingivectomy, apically displaced flap with or without resective osseous surgery, and surgical extrusion using periotome. Objective: The aim of this paper is to compare clinically the three different surgical techniques of crown lengthening procedures. Materials and Methods: Fifteen patients who reported to the department of Periodontology, were included in the study. Patients were randomly divided into three groups, which include patients who underwent gingivectomy (Group A, apically repositioned flap (Group B and surgical extrusion using periotome (Group C. Clinical measurements such as clinical crown length, gingival zenith, interdental papilla height were taken at baseline and at 3 rd month post-operatively. Results: Clinical and radiographic evaluation at 3 rd month suggest that surgical extrusion technique offers several advantages over the other conventional surgical techniques such as preservation of the interproximal papilla, gingival margin position and no marginal bone loss. Conclusions: This technique can be used to successfully treat a grossly damaged crown structure as a result of tooth fracture, dental caries and iatrogenic factors especially in the anterior region, where esthetics is of great concern.

    The aim of phase II clinical trials is to determine whether an experimental treatment is sufficiently promising and safe to justify further testing. The need for reduced sample size arises naturally in phase II clinical trials owing to both technical and ethical reasons, motivating a significant part of research in the field during recent years, while another significant part of the research effort is aimed at more complex therapeutic schemes that demand the consideration of multiple endpoints to make decisions. In this paper, our attention is restricted to phase II clinical trials in which two treatments are compared with respect to two dependent dichotomous responses proposing some flexible designs. These designs permit the researcher to terminate the clinical trial when high rates of favorable or unfavorable outcomes are observed early enough requiring in this way a small number of patients. From the mathematical point of view, the proposed designs are defined on bivariate sequences of multi-state trials, and the corresponding stopping rules are based on various distributions related to the waiting time until a certain number of events appear in these sequences. The exact distributions of interest, under a unified framework, are studied using the Markov chain embedding technique, which appears to be very useful in clinical trials for the sample size determination. Tables of expected sample size and power are presented. The numerical illustration showed a very good performance for these new designs.

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

    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.

    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)

    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

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.

    Literature appreciation usually follows a"writer-text-reader" process. The author is an inseparable part in literary discussion. Most literary schools have debate on the author's status, which is mainly sorted into two kinds: reliable author or unreliable author. This paper makes a comparative study on the author's status, which is mainly from the perspectives of New Criticism and Deconstruction. Both of them go for unreliability of the author. They share similarities but also bear differences.

    2012-10-01

    Over the last decade, maggot debridement therapy (MDT) has been recognized by many clinicians as a potential adjunct to conventional therapy, and many patients with non healing, chronic ulcers have been treated. Numerous case reports and case series have described the successful use of MDT in a variety of ulcers. However, comparative clinical trials and in particular randomized controlled trials investigating the efficacy of MDT are sparse. A systematic search in the literature showed three randomized clinical trials and five non randomized studies evaluating the efficacy of sterile Lucilia sericata applied on ulcers with various aetiologies. Of these, seven studies had debridement and/or healing as an outcome variable. When evaluating maggots as debriding agents, the studies report MDT as being significantly more effective than hydrogel or a mixture of conventional therapy modalities, including hydrocolloid, hydrogel and saline moistened gauze. However, the design of the studies was suboptimal, with important differences in the use of other therapies, such as compression, that may influence both debridement and healing between the compared groups, as well as inappropriately short follow-up times. The quality of the studies therefore makes it difficult to conclude that MDT shortens healing time. The poor quality of the data used for evaluating the efficacy of MDT highlights the need for more and better designed investigations.

    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 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.

    Suicide is a major clinical problem in psychiatry and suicidal behaviours can be seen as a nosological entity per se. Predicting suicide is difficult due to its low base-rate and the limited specificity of clinical predictors. Prospective biological studies suggest that dysfunctions in the hypothalamo pituitary adrenal (HPA) axis and the serotonergic system have predictive power for suicide in mood disorders. Suicide attempt is the most robust clinical predictor making suici...

  16. EFQPSK Versus CERN: A Comparative Study

    Science.gov (United States)

    Borah, Deva K.; Horan, Stephen

    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

  17. A Comparative Study of Mammalian Diversification Pattern

    Directory of Open Access Journals (Sweden)

    Wenhua Yu, Junxiao Xu, Yi Wu, Guang Yang

    2012-01-01

    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.

    Objective To compare the differences of the clinical effects, side effects and treatment-related cost between two kinds of negative-pressure wound therapy (NPWT). Methods Forty-four inpa-tients with acute, subacute, and chronic wounds were divided into simplified NPWT group ( A group) and conventional NPWT group ( B group) according to the random number table. Wounds of patients in A group were treated with gauze + continuous suction with hospital central negative pressure ( -10.64 kPa) for 24 hs; wounds of patients in B group were treated with sponge + interrupted suction with a purpose-designed suction appliance ( -16.63 kPa) for 24 hs.

    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.

  4. 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)

    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.

    Full Text Available Aim. To evaluate in open 12 month prospective, randomized study the mortality and recurrent cardiovascular events rate, dynamics of neurological deficit, endothelial dysfunc- tion and renal function in patients with the first ischemic stroke of hemispheric localization after prescription of simvastatin 40 mg daily in the acute stage of the disease. Material and methods. Patients (n=210 above 18 years of age (95 men and 115 women with acute ischemic stroke were included into the study. Patients were randomized into two groups. Patients of the group 1 (n=105 received standard treatment for ischemic stroke. Patients of the group 2 (n=105 received simvastatin 40 mg/day additional- ly to standard therapy of stroke. Follow-up duration was 12 months. The lipid profile, a number of desquamated epithelial cells circulating in the blood, glomerular filtration rate (GFR according to MDRD, as well as neurological patient status (Scandinavian Scale, MMSE, NIHSS were monitored.Results. During the follow-up period mortality was 18.1% and 15.2% in group 1 and 2, respectively. Composite end point was achieved in 60.9% and 46.6% of patients, re- spectively (p=0.037. 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.

    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

    Full Text Available Two antimicrobial agents, a fixed combination of essential oils (EOs and 0.07% cetylpyridinium chloride (CPC are found in commercially available mouthrinses, Listerine® Antiseptic and Crest® Pro HealthTM, respectively. Both mouthrinses have been shown to control dental plaque and gingivitis in short and longer term studies. The aim of this study was to determine the comparative effectiveness of these two mouthrinses using a 2-week experimental gingivitis model. Qualified subjects were randomly assigned to one of three mouthrinse groups: a fixed combination of EOs, 0.07% CPC, or negative control (C rinse. Following baseline clinical assessments and a dental prophylaxis, subjects began a two-week period in which they rinsed twice daily with their assigned rinse and abstained from any mechanical oral hygiene procedures or other oral care products. Subjects were reassessed at the end of the two-week period. One hundred and forty-seven subjects were randomized and 142 completed this study. After two weeks use, the EOs rinse was superior (p < 0.011 to the CPC rinse in inhibiting the development of gingivitis, plaque, and bleeding, with 9.4% and 6.6% reductions compared to CPC for gingivitis and plaque, respectively. Both rinses were superior to the negative control rinse (p < 0.001. This study demonstrates that the essential oil-containing mouthrinse has superior antiplaque/antigingivitis effectiveness compared to the 0.07% CPC-containing mouthrinse without mechanical oral hygiene influence.

    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.

  14. Synergistic effect of various virulence factors leading to high toxicity of environmental V. cholerae non-O1/ non-O139 isolates lacking ctx gene : comparative study with clinical strains.

    Directory of Open Access Journals (Sweden)

    Neha Rajpara

    Full Text Available BACKGROUND: Vibrio cholerae non-O1/ non-O139 serogroups have been reported to cause sporadic diarrhoea in humans. Cholera toxins have been mostly implicated for hypersecretion of ions and water into the small intestine. Though most of the V. cholerae non-O1/ non-O139 strains lack these cholera toxins, several other innate virulence factors contribute towards their pathogenicity. The environmental isolates may thus act as reservoirs for potential spreading of these virulence genes in the natural environment which may cause the emergence of epidemic-causing organisms. RESULTS: The environmental isolates of vibrios were obtained from water samples, zooplanktons and phytoplanktons, from a village pond in Gandhinagar, Gujarat, India. They were confirmed as Vibrio cholerae non-O1/ non-O139 using standard biochemical and serotyping tests. PCR experiments revealed that the isolates lacked ctxA, ctxB, tcpA, zot and ace genes whereas other pathogenicity genes like toxR, rtxC, hlyA, hapA and prtV were detected in these isolates. Compared with epidemic strain V. cholerae O1 El Tor N16961, culture supernatants from most of these isolates caused higher cytotoxicity to HT29 cells and higher hemolytic, hemagglutinin and protease activities. In rabbit ileal loop assays, the environmental isolates showed only 2-4 folds lesser fluid accumulation in comparison to N16961 and a V. cholerae clinical isolate IDH02365 of 2009. Pulsed Field Gel electrophoresis and Random amplification of Polymorphic DNA indicated that these isolates showed considerable diversity and did not share the same clonal lineage even though they were derived from the same water source. All the isolates showed resistance to one or more antibiotics. CONCLUSION: Though these environmental isolates lacked the cholera toxins, they seem to have adopted other survival strategies by optimally utilising a diverse array of several other toxins. The current findings indicate the possibility that these

  15. 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

    ObjectiveTo compare the clinical effects of three instruments on root canal retreatment and discuss the application characteristics of two NiTi instruments.Methods A total of 177first molars of 173 patients were selected. These molars would receive root canal re-treatmentdue to failed root canalfilling. Eighty-fourfirst molars sensitive to percussion afterfirst root canal treatment were divided into three groups: group TF1(n=28), group Protaper D1(n=28), group stainless steel file1(n=28). The other ninety-three pain-free molars were randomly divided into three groups: group TF2(n=31), group Protaper D2(n=31), group stainless steelfile2(n=31). Preparation time comparisons among these groups were tested by variance analysis, while incidence rates of postoperative pain or remission rates of preoperative pain and equipment damage among groups were analyzed by chi-square test.ResultsThe preparation time in group TF was significantly shorter than that in group ProtaperD and stainless steelfile respectively(P=0.00). The painless rates or remission rates of group TF were greater than group stainless steelfile (P<0.01). Tightented or loosened spiral was detected in 60 TFfiles. One Protaper Dfile was fractured.ConclusionThe application of TF rotary NiTi instrument for root canal retreatment could more effectively relieve intraoperative pain and reduce operative time compared with stainless steelfile.TF rotary NiTi instrument was more suitable for curved root canal , but it was also more prone to occur spiral deformation.%目的:比较3组器械在根管再治疗中的临床应用效果,探讨其中2种镍钛器械的应用特点。方法选择173例因根充不实或欠填需根管再治疗的177颗第一恒磨牙作为研究对象,84颗患牙均有叩痛,经首次根管治疗后出现自觉症状,随机分为3组(TF1组、Protaper D1组和不锈钢锉1组),每组各28颗;93颗无叩痛患牙,也随机分为3组(TF2组、Protaper D2组和不锈钢锉2

    Full Text Available BACKGROUND Laryngoscopy and endotracheal intubation results in physiological changes of various body systems like heart rate and blood pressure in cardiovascular system. For attenuating the hyperdynamic cardiovascular response to tracheal intubation, numerous trials with many drugs were undertaken. AIM Of our study is to find out the safety and efficacy of attenuation of pressor response during laryngoscopy and tracheal intubation using Esmolol, administered as single intravenous bolus prior to induction of anaesthesia in two different doses of 1.5 mg/kg and 2.25 mg/kg. Control group was considered in our previous study using the same drug with different dosage, i.e. a dose of 0.75 mg/kg was compared with a placebo. We would like to go ahead with further increase in the dosage per kg body weight to get an ideal suppression of the pressor responses. MATERIALS AND METHODS The study was conducted in 50 patients, who were randomly assigned into 2 groups of 25 each. Group A (25 received Inj. Esmolol 1.5 mg/kg and Group B (25 received Inj. Esmolol 2.25 mg/kg IV before induction. RESULTS Heart rate and blood pressures were well maintained within physiological range in Group A, whereas there was a decrease in blood pressure and heart rate in the Group B immediately after intubation and at the end of 4th min. CONCLUSION In this study, the Group B showed an inappropriate decrease in mean values of Heart Rate, Blood Pressure immediately after administration.

    Advancing the clinical trial research process to improve cancer treatment necessitates helping people with cancer identify and enroll in studies, and researchers are using the power of the Internet to facilitate this process. This study used a content analysis of online cancer clinical trial search tools to understand what people with cancer might encounter. The content analysis revealed that clinical trial search tools were easy to identify using a popular search engine, but their functionality and content varied greatly. Most required that users be fairly knowledgeable about their medical condition and sophisticated in their web navigation skills. The ability to search by a specific health condition or type of cancer was the most common search strategy. The more complex tools required that users input detailed information about their personal medical history and have knowledge of specific clinical trial terminology. Search tools, however, only occasionally advised users to consult their doctors regarding clinical trial decision-making. This, along with the complexity of the tools suggests that online search tools may not adequately facilitate the clinical trial recruitment process. Findings from this analysis can be used as a framework from which to systematically examine actual consumer experience with online clinical trial search tools.

  3. COMPARATIVE STUDY ON ACCOUNTING AND FISCAL AMORTIZATION

    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.

  4. Comparative study of silicon empirical interatomic potentials

    1992-07-01

    We have performed a comparative study of six classical many-body potentials for silicon (Pearson, Takai, Halicioglu, and Tiller; Biswas and Hamann; Stillinger and Weber; Dodson, Tersoff 2, and Tersoff 3). Extensive static calculations have been performed using these potentials on Sin clusters (n=2-6), bulk point defects, elastic constants, polytypes, pressure-induced phase transformations, and surfaces [(111), (100), and (110)]. Similarities and differences between the six potentials have been identified, and their transferability as well as their accuracy with respect to experiment and first-principles methods have been assessed. In general, all of these potentials do a relatively poor job of modeling the energetics of small clusters as well as the various reconstructions of the Si(111) surface. They provide a fair to good description of the properties of bulk diamond cubic silicon, its intrinsic defects, and the Si(100) surface. Besides the fact that none of them models π bonding, their inability to be more transferable lies in their inadequate description of the angular forces. Each potential has its strengths and limitations, but none of them appears to be clearly superior to the others, and none is totally transferrable. However, despite their shortcomings we feel that some of these potentials will be useful in large-scale simulations of materials-related problems. They can give valuable insights into phenomena that are otherwise intractable to investigate either experimentally or via first-principles methods.

  5. 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

    Full Text Available Introduction: Mechanical plaque control is the main way to prevent caries and periodontal diseases. Among the mechanical methods, daily use of toothbrush is considered as the best way to achieve oral health. Therefore, the purpose of this study was to evaluate clinical and microbiological efficacy of Hygenic toothbrushes in plaque removal. Methods: In this randomized clinical trial, 40 volunteers were selected. Patients were randomly divided into two groups, one group received toothbrushes with battery and the other group received toothbrushes without the battery. At the beginning of the study plaque score was measured and recorded. Patients brushed for a week and plaque was measured again. Then in both groups the first toothbrush was taken and the second brush was received by the volunteers in a cross over manner. In this regard, the mirobiological samples (colony forming units were determined before and after brushing. Data was analyzed by means of T- tests using the spss software. Results: The results showed that toothbrushes with and without battery reduced plaque score (respectively 98/22% and 26/19%. Colony forming units was reduced for both toothbrushes with battery (6/24% and without battery (9/5%. This indicates that toothbrushes with battery significantly reduced plaque compared to the ordinary toothbrushes. Conclusion: Hygenic toothbrushes reduce plaque score and microbial counts more effectively than ordinary toothbrushes.

    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.

    Objective To evaluate the predictive values of different systems for clinical staging of esophageal carcinoma in one group of patients and improve the criteria for T staging,and to provide a basis for accurate clinical staging. Methods A retrospective study was performed in 701 patients with esophageal carcinoma who received radical radiotherapy in our hospital. The prognosis was performed according to American Joint Committee on Cancer ( AJCC) tumor-node-metastasis staging system,Chinese 2004 staging system,the draft of Chinese 2009 staging system,and gross tumor volume of the primary tumor (GTV-T). Results In terms of T stage,patients evaluated according to the AJCC staging system were in relatively early stages;23. 1% of them were in stage T1,and the survival curves of T3 and T4 patients were close to each other;the survival curves plotted according to the Chinese 2004 staging system were well separated, but relatively few patients were in stages T1 and T4 , yielding an uneven distribution;according to the draft of Chinese 2009 staging system, the survival curve of T3 patients intersected that of T4 patients, and up to 43. 2% of patients were in stage T4.The new T staging was performed based on GTV and the extent of tumor invasion into the adjacent tissue and organ, and the results showed that there was no intersection between survival curves and a relatively balanced T stage distribution. In terms of N staging,patients were divided into stages N0 ,N1 ,and N2 . The TNM staging was performed by a combination of N staging and new T staging, resulting in significant separation between survival curves ( P=0. 000) . Conclusions The combination of T staging,which is based on GTV and the extent of tumor invasion,and N staging,which is based on metastasis of lymph nodes, can accurately predict the survival of non-surgically treated patients with esophageal carcinoma.%目的 比较不同食管癌临床分期对同一组病例的预测价值,并完善T分期标准,为更

    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)

    2016-07-01

    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).

    2015-01-01

    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

    Thirty-five hospitalized catatonic schizophrenic patients from Sri Lanka were compared with 22 patients in the U.K. and 13 in Canada. The phenomenology was established using the Present State Examination. Results suggest that ethnicity, chronicity of illness and reception of neuroleptic treatment may influence the lower prevalence of catatonic symptoms among the U.K. and Canadian schizophrenics. Onset of illness appears to be among young adults and mutism, stupor, mannerisms, stereotypes and negativism were the common catatonic symptoms observed.

    Full Text Available HgBa2CaCu2O6+δ (Hg -1212 thin films were fabricated by exchanging the T1 cations in TlBa2CaCu2O7-δ (Tl-1212 thin films with Hg cations, causing a 30-K increase in Tc. To determine how this exchange effects such a Tc increase, the irreversibility lines, temperature dependence of critical current density, and temperature dependence of Hall angle ofHg-1212 and TI-1212 thin films were measured and then compared. The results strongly suggest that the Tc shift is caused by a doubling of charge carrier density.

    In France, official guidelines for good clinical practices in clinical trials were issued in 1987. In December 1988, a law was passed that fixed the requirements for carrying out experiments in healthy subjects. It will be completed by official guidelines for the structures in which experiments on healthy subjects (and patients as well, when the investigation would not benefit the health of the patients) may be conducted. Hence a battery of recent legal instructions precisely state what good clinical practices are in the setting of phase I studies. Of particular importance are: subject recruitment and selection methods and procedures; specific competence of the investigator, in particular to interpret the pre-trial data; necessary and sufficient facilities to guarantee the subjects' safety; careful quality control to check all laboratory procedures; necessity of written standard operating procedures.

    2012-01-01

    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.

  13. Comparative study of tricarbonyl complexes fluconazole and voriconazole fungal

    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 Objectives: Patello femoral Pain (PFP is the most common lower limb condition encountered in clinical practice. It recently emerged as the third highest ranked topic out of 185 in the Chartered Society of Physiotherapy Musculoskeletal Research Priority Project. For a valid assessment of knee strength during rehabilitation, the isometric test using the isokinetic dynamometer (Cybex and the hand-held dynamometer (HHD is not well received with clinical practice. An alternative way is through functional hop tests which clinicians have used to assess their patients' lower extremity muscular strength. This study investigates the validity of knee strength assessments conducted with the HHD and the hoptest compared to the isokinetic dynamometer and also explores differences between genders of the three assessments. Design: Each assessment included one submaximal and three recorded maximal efforts of the dominant leg. Quadriceps muscle strength was displayed in normalized torques. Correlation coefficients and box-and-whisker plots was used to analyze the data. Setting: Movement analysis laboratory Participants: Sixteen males (age 23.5 ± 4.23 years, height 1.79 ± 0.08 m and body mass 76.21 ± 10.58 kg, BMI 23.82 ± 2.38 kg/m² and 16 females (age 25.38 ± 5.49 years, height 1.67 ± 0.08 m and body mass 71.99 ± 16.05 kg, BMI 25.83 ± 4.74 kg/m² between 18 and 40 years old without any musculoskeletal injuries participated. Main outcome measures: Knee moments normalized for bodyweight (Nm/kg for dynamometers and distance jumped for single legged hoptest. Results: The strongest significant correlation was found for the comparison between the HHD and Cybex (r=0.71, r²=0.504, p=0.001. Correlation between the HHD and hoptest (r=0.4, r²=0.19, p=0.013, and Cybex and hoptest (r=0.53, r²=0.295, p=0.001 were poor. Comparing genders, the normalized knee extension moment on the Cybex was 28.8% lower and with the HHD 22.3% lower for females. Conclusions: Single

    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.

    Full Text Available Background: With the increasing rate of oral diseases, the global necessity of effective and economical products for its prevention and treatment has intensified. 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.

    Hans Strahl, a contemporary of Duval and Hubrecht, made many important contributions to comparative placentation. Despite this he is not well known and some of his original observations tend to be attributed to later authors. Strahl published a classification of placental types based on their shape and relationship to maternal tissues. This greatly influenced the work of Otto Grosser, who became better known in part because his work was more accessible to other scientists and clinicians. Strahl described the development of the fetal membranes across a broad range of mammalian orders extending his observations beyond parturition to the post partum involution of the uterus. He paid close attention to structures designed for histotrophic nutrition including the areolae of moles, haemophagous organs of carnivores and tenrecs and chorionic vesicles of lemurs and lorises. We here provide a summary of some of the most important findings made by Strahl including work on placentation in carnivores and higher primates that remains unsurpassed.

  20. Earthquake Correlations and Networks- A Comparative Study

    We quantify the correlation between earthquakes and use the same to distinguish between relevant causally connected earthquakes. Our correlation metric is a variation on the one introduced by Baiesi and Paczuski (2004). A network of earthquakes is constructed, which is time ordered and with links between the more correlated ones. Recurrences to earthquakes are identified employing correlation thresholds to demarcate the most meaningful ones in each cluster. Data pertaining to three different seismic regions, viz. California, Japan and 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 ...

    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 c2 and p values for the clinical data and the CPS data after the 12 months concluded.

    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.

    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.

    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.

    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.

    Full Text Available Background : Study of fibrilar, cellular and sub cellular structures of mineralized tissues is only possible after the removal of the calcium apatite of these tissues by the process of demineralization. Aims: The present study aims to evaluate six commonly used demineralizing agents to identify the best decalcifying agent. Materials and Methods: The present study included six different decalcifying solutions: 10% formal nitric acid, 8% formal nitric acid, 10% formic acid, 8% formic acid, Perenyi′s fluid and Ethylene Di-Amine Tetra Acetic Acid. eight samples of posterior mandible of rat were decalcified in each of the decalcifying solutions and subjected to chemical end-point test. Ehrlich′s Hematoxylin stain was used. Statistical Analysis Used: One way ANOVA was used for multiple group comparisons and Chi-square test was used for analyzing categorical data. P value of 0.05/less was set for statistical significance. Results: Samples treated with EDTA showed the best overall histological impression and the tissue integrity were well preserved. Formal nitric of both the percentages 10 and 8% gave fairly good cellular detail and were rapid in their action. Conclusion: The final impression led to the proposition that EDTA was indeed the best decalcifying agent available. However, with time constraint, the use of formal nitric acid is advocated.

  20. To evaluate the efficacy of ultrasonography compared to clinical diagnosis, radiography and histopathological findings in the diagnosis of maxillofacial swellings

    International Nuclear Information System (INIS)

    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.

    2013-01-01

    Modelling AGN feedback in numerical simulations is both technically and theoretically challenging, with numerous approaches having been published in the literature. We present a study of five distinct approaches to modelling AGN feedback within gravitohydrodynamic simulations of major mergers of Milky Way-sized galaxies. To constrain differences to only be between AGN feedback models, all simulations start from the same initial conditions and use the same star formation algorithm. Most AGN feedback algorithms have five key aspects: black hole accretion rate, energy feedback rate and method, particle accretion algorithm, black hole advection algorithm, and black hole merger algorithm. All models follow different accretion histories, with accretion rates that differ by up to three orders of magnitude at any given time. We consider models with either thermal or kinetic feedback, with the associated energy deposited locally around the black hole. Each feedback algorithm modifies the gas properties near the black ...

    Comparative genomic hybridization (CGH) offers a new global approach for detection of chromosomal material imbalances of the entire genome in a single experiment without cell culture. In this paper, we discuss the technical development and the cytogenetic aspects of CGH in a clinical laboratory. Based only on the visual inspection of CGH metaphase spreads, the correct identification of numerical and structural anomalies are reported. No commercial image analysis software was required in these experiments. We have demonstrated that this new technology can be set up easily for routine use in a clinical cytogenetics laboratory.

    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.)

    Post-traumatic headache (PTH) is the most frequent symptom after traumatic brain injury (TBI). We review the epidemiology and characterization of PTH in military and civilian settings. PTH appears to be more likely to develop following mild TBI (concussion) compared with moderate or severe TBI. PTH often clinically resembles primary headache disorders, usually migraine. For migraine-like PTH, individuals who had the most severe headache pain had the highest headache frequencies. Based on studies to date in both civilian and military settings, we recommend changes to the current definition of PTH. Anxiety disorders such as post-traumatic stress disorder (PTSD) are frequently associated with TBI, especially in military populations and in combat settings. PTSD can complicate treatment of PTH as a comorbid condition of post-concussion syndrome. PTH should not be treated as an isolated condition. Comorbid conditions such as PTSD and sleep disturbances also need to be treated. Double-blind placebo-controlled trials in PTH population are necessary to see whether similar phenotypes in the primary headache disorders and PTH will respond similarly to treatment. Until blinded treatment trials are completed, we suggest that, when possible, PTH be treated as one would treat the primary headache disorder(s) that the PTH most closely resembles.

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

    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.

    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.

  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.

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.

    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.

  1. Clinical studies of neuroinflammatory mechanisms in schizophrenia.

    Watkins, Crystal C; Andrews, Sarah Ramsay

    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.

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.)

    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. .

    Full Text Available BACKGROUND AND OBJECTIVES: The clinical profile of patients with hypertensive emergencies presenting to rural hospitals in a developing country like ours is unknown. The objective of the present study was to evaluate the modes of presentations, clinical profile and spectrum of target organ damage in patients with hypertensive emergencies. METHOD: This observational study was done at SRI ADICHUNCHANGIRI INSTITUTE OF MEDICAL SCIENCES AND REASEARCH CENTER over a period of one and a half years. The study population included patients admitted to this hospital with severely elevated blood pressure with clinical or laboratory evidence of acute target organ damage. The clinical and laboratory profile of 50 patients were evaluated. RESULTS: Males had higher chances of developing a hypertensive emergency compared to females, male: female ratio 2.57:1. The commonest presenting symptoms were neurological deficit (50%, dyspnea (30%, followed by chest pain (24%. Majority of the patients were known hypertensive (70%. Higher levels of blood pressure at presentation were associated with an adverse outcome. Laboratory abnormalities noticed in these patients included hyponatremia and hyperkalemia. Acute intracerebral hemorrhage was the commonest mode of target organ damage. An in hospital mortality of 24% was observed in the present study.

    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.

    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.

  11. 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)

  12. 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

    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

Two groups of patients were defined according to inpatient (group 1 or outpatient (group 2 surgery, and a comparison of several parameters between these two groups was performed.Results: Of the 80 subjects in this study, the average age of group 1 (50 patients was 49.7 years, and that of group 2 (30 patients was 47.5 years. There were no statistically significant differences in the average logarithm of the minimum angle of resolution-visual acuity, the condition of the lens, or the presence of retinal lattice degeneration prior to the surgery between the groups. There were no statistically significant differences in the patterns of tear or retinal detachment or in surgical procedure between the groups. Comparing the best-corrected visual acuity after 6 months with that prior to the surgery, the changes in group 1 and group 2 were 0.26 and 0.31, respectively. The functional success rates of group 1 and group 2 after 6 months were 90% and 93%, respectively, and the anatomical success rates of group 1 and group 2 after 6 months were 94% and 96%, respectively, but these were also statistically insignificant.Conclusion: Hospitalization is not essential for buckling surgery in uncomplicated rhegmatogenous retinal detachment surgery.Keywords: ambulatory, scleral buckling, rhegmatogenous retinal detachment

    2011-06-01

    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.

    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.

  19. 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

  3. 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 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.

    Full Text Available A new manufacturing method of twisting nickel titanium wire to produce rotary nickel titanium (RNT files has recently been developed. The aim of the present study was to evaluate whether the new manufacturing process increased the angular deflection of RNT files, by comparing instruments produced using the new manufacturing method (Twisted Files versus instruments produced with the traditional grinding process. Testing was performed on a total of 40 instruments of the following commercially available RNT files: Twisted Files (TF, Profile, K3 and M2 (NRT. All instruments tested had the same dimensions (taper 0.06 and tip size 25. Test procedures strictly followed ISO 3630-1. Data were collected and statistically analyzed by means ANOVA test. The results showed that TF demonstrated significantly higher average angular deflection levels (P<0.05, than RNT manufactured by a grinding process. Since angular deflection represent the amount of rotation (and consequently deformation that a RNT file can withstand before torsional failure, such a significant improvement is a favorable property for the clinical use of the tested RNT files.

    The methodology developed includes both the use of laboratory evaluation and clinical assessment in an area where there are no standard requirements, no specifications, nor any continuity of data available on the various thermoplastic splinting materials now on the market. A series of laboratory tests and clinical trials were devised such that these could be interpreted with regard to clinical considerations, cost analyses and serviceability factors relating to the materials. Laboratory testing covered possible effects on the chemical and mechanical properties of material likely to be caused by various environmental, sterilization and working factors. The complementary clinical evaluation to highlight the behaviour of materials during the fabrication and wearing of splints consisted of specific information generated with the assistance of experienced occupational therapists, occupational therapy students and patients. Biocompatibility studies were also carried out. The data to be published will provide needed information to physicians, occupational therapists, physical therapists, orthotists, prosthetists, and administrators with regard to their making informed decisions on the selection, purchase and use of thermoplastic materials.

    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.

    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

    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

    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

    Full Text Available Carcinoma of the breast is one of the commonest cancers occurring in female and accounts for 1/3rd of all the malignant diseases occurring in them. It is mainly a disease of the developed countries and accounts for 1,00,000 deaths annually. Breast carcinoma is classified as Early breast cancer, Locally advanced breast cancer and Metastatic breast cancer. By definition early stage breast cancer constitutes breast tumors of clinical stages I, IIa and T2N1M0. Early breast cancer is the one diagnosed by mammography. Women when approaches at this stage, they can go for breast conservation surgery. Not all women are candidates for this approach, and some require mastectomy as part of their treatment. AIM To observe the incidence of early breast carcinoma with particular reference to the time taken by the patients to seek medical advice after the symptoms have developed i.e. the average time taken by the patients to seek medical advice, their appropriate management and prognosis. MATERIALS AND METHODS This prospective study was conducted over a period of 2 years from Oct-2012 to Oct-2014 in 30 female patients aged between 25-65 years who were presented with lump in breast of size ≤5cms with or without pain, with or without lymph nodes to the outpatient department. All the patients were thoroughly asked about history, examined clinically, investigated, staged and managed by surgery either Breast Conservation Surgery or Modified Radical Mastectomy. Postoperative complications were recorded and followed up regularly. RESULTS The incidence of early breast cancer in this study was 0.98% with peak age incidence between 40-60 years and duration of symptoms <6 months in 18 patients. Breast Conservation Surgery + axillary dissection + Radiotherapy was done in 23%. Prognosis was good in these patients with no local recurrence and death. CONCLUSION The prognosis of early stage breast carcinoma patients in this study was good. To have long term tumor free and

    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.

    Voluntary counseling and testing (VCT) for couples (CVCT) is an important HIV-prevention effort in sub-Saharan Africa where a substantial proportion of HIV transmission occurs within stable partnerships. This study aimed to determine the acceptance and effectiveness of CVCT as compared to individual VCT (IVCT). 1,521 women attending three antenatal clinics in Dar es Salaam were randomized to receive IVCT during that visit or CVCT with their husbands at a subsequent visit. The proportion of women receiving test results in the CVCT arm was significantly lower than in the IVCT arm (39 vs. 71%). HIV prevalence overall was 10%. In a subgroup analysis of HIV-positive women, those who received CVCT were more likely to use preventive measures against transmission (90 vs. 60%) and to receive nevirapine for themselves (55 vs. 24%) and their infants (55 vs. 22%) as compared to women randomized to IVCT. Uptake of CVCT is low in the antenatal clinic setting. Community mobilization and couple-friendly clinics are needed to promote CVCT.

    Full Text Available Objective: To study the effect of cigarette smoking on seminal fluid parameters, namely; volume, sperm concentration, and motility, as well as morphology, leukocyte infiltration, among males complaining of infertility.Methods: Between August 2010 and July 2011, seminal fluid analysis was done for 1438 males who are partners of couples who visited the infertility clinic at Prince Rashid Ben Al Hassan Hospital (PRH for infertility. The men who fit the inclusion criteria (n=960 were classified into two groups: group a (non-smokers; n=564 and group B (smokers; n=396, which represents 41.25% of the study group. Seminal fluid was collected using masturbation after 3-5 days of abstinence then analyzed for volume, sperm count, sperm concentration, motility and morphology. In order to analyze whether the number of cigarettes smoked per day has an effect on the spermatogram; the smoking men were divided into two subgroups: the heavy smokers (n=266 and non-heavy smokers (n=130.Results: A total of 960 adult males were enrolled. Their age ranged between 21 and 76 years, 564 were non-smokers with mean age of 36. 45±6.27 (Mean±SD. Three-hundred-and-ninety-six were smokers with a mean age of 34.35±4.25 (Mean±SD. There was a significant effect of smoking on the motility of sperms and the ratios of abnormality (p<0.005. Concentration appeared not to be affected by smoking. Furthermore, the group of heavy smokers were found to have lower sperm concentrations and a higher percentage of abnormal sperms compared to the non-heavy smokers.Conclusion: Cigarette smoking has a deleterious effect on some of the seminal fluid parameters (motility, morphology and leukocyte count which in turn may result in male subfertility.

    Mucoceles are commonly occurring lesions of the oral mucous membrane and the most common lesion involving minor salivary tissue. The incidence of mucoceles is understandable since accessary salivary gland tissue is widely distributed throughout the oral mucous membrane and trauma to the mucosa, which causes their formation, occurs frequently. But only a few studies have been reported that describe its detailed features. This is a retrospective study on the salivary mucoceles in the oral mucous membrane and based on clinical chart, biopsy request and photomicroscopic finding of 112 patients treated by Dept. of Oral Surgery in Seoul National University Hospital, during the period of last 10 years. The results were as following. 1. The age range of the 112 patients was 2 to 60 years, with a peak incidence in the second decade and a gradual decline thereafter. Of the 112 patients, 49 (44%) were males and 63 (56%) were females, the male-to-female ratio being 1:1.29. 2. The majority of these lesions were located on the lower lip but occurred with lesser frequently on the buccal mucosa, floor of the mouth, tongue, retromolar region, upper lip. 3. Of the 112 patients, 107 (95%) were treated by excision and only 5 were treated by marsupialization. 18 of 112 cases had recurrence and the recurrence rate in this study was 16%. 4. Only 3 of the 112 cases revealed an epithelial lining. This incidence indicates that the mucus-extravasation by the damage of excretory duct rather than the ductal dilatation by mucus-retention may play a critical role in the production of these lesions. 5. In 81 cases (72.3%) minor salivary gland were included in the excision biopsy, specimen. Changes observed in the glandular tissue were atrophy and infiltration of chronic inflammatory cell, but the secretory function of gland was thought to be normal in most cases because the changes were mild.

    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.

    1994-12-01

    Our study included 42 patients with obstructive sleep apnea (OSAS) confirmed by polysomnography. In these patients we investigated the clinical manifestations, the results of the laboratory examinations, including polysomnography, ORL observations and tests of pulmonary function, as well as the therapeutic results. Our patients presented a serious set of symptoms which included excessive daytime sleepiness, snoring, obesity, craniofacial abnormalities, systemic hypertension, cardiac arrhythmias, incapacity to work with precocious retirement, marital conflicts and high incidence of accidents, namely traffic accidents. An adequate treatment, mostly with nasal CPAP (continuous positive airway pressure), induced marked relief of the symptoms; some patients had an advantage in surgical treatment and weight reduction. OSAS is a frequent entity, affecting mostly male adults after the 5th decade. The lack of knowledge about this entity and the common social acceptance of some of its cardinal symptoms induces considerable delays in its diagnosis. The severity of the symptoms, the personal and social risks of excessive daytime sleepiness, the cardiocirculatory effects and the risk of sudden death during sleep justify an early diagnosis in order to prevent the severe evolution of the disease. Its complex physiopathology and multiple etiological factors justify a multidisciplinary approach. PMID:7653280

    We studied the relationship between outcome and clinical symptoms or CT findings of 34 cases with primary pontine hemorrhage diagnosed by CT scan from April 1994 to March 1999. This series comprised 19 males and 15 females ranging in age from 45 to 89 years with a mean of 67.1 years. According to their outcome at discharge, the cases were divided into 6 groups. Sixteen cases died within 2 weeks after onset (group AD), 4 cases died with complication in the chronic phase (group D), 3 cases were severely disabled to bed-ridden state (group C), 2 cases recovered to a daily life with wheelchair (group B), 4 cases recovered to a daily life with partial assistance (group A), and 5 cases showed a full recovery (group J). The factors significantly correlated with bed outcome are as follows: young age, consciousness disturbance, respiratory disturbance, tachycardia over 90 beats per minute, hyperthermia over 39 deg C, abnormal pupils, loss of oculocephalic reflex, tetraplegia, decerebrate rigidity, bilateral extension or over 30 mm transverse diameter of the hematoma.

    Yin, Hang; Pardue, Machelle T

    2004-01-01

    To compare the recording characteristics of the DTL fiber and Jet contact lens electrodes, ERG responses were recorded from 20 normal subjects using the ISCEV standard clinical protocol. In each subject, the DTL electrode was placed in the right eye and the Jet contact lens in the left eye after 30 min of dark-adaptation. After presenting standard dark- and light-adapted stimuli, each response was analyzed for a- and b-wave amplitude and implicit time. Each subject was then asked to rate the comfort of each electrode. Responses recorded with the DTL are larger and faster for the dark-adapted dim white and red flashes. In contrast, the Jet electrode records larger responses for the dark-adapted standard flash and light-adapted flashes. Of these differences, only the standard flash is statistically significant. However, overall the DTL electrode has greater variability than the Jet electrode across all recordings. The DTL and Jet electrodes cannot be used interchangeably as demonstrated by a Bland and Altman analysis of agreement. Thus, separate normative values need to be collected for each type of electrode to accurately assess retinal function. Based on the comfort assessment of the two electrodes, the subjects preferred the DTL electrode over the Jet electrode. Due to the superior comfort level of the DTL and its similarities to the Jet contact lens electrode in ERG recordings, the DTL electrode appears to be a good alternative to the Jet electrode in routine clinical testing when used with the appropriate normative values.

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

    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.

    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. Hospital (attached to Government Medical College, Mysore during the study period December 1, 2008 to May 31, 2010. REUSLTS: Age Incidence, Sex Incidence, Socio Economic Status, Modes of Presentation, No. of External Openings, Situation of External Openings, Level of Fistulae, Type of surgical treatment, Associated with Fissure in Ano, Postoperative complication and Results were studied. CONCLUSION: Commonest age of presentation in our series is 30-40 years – 40%. Males are more commonly affected. Ratio Male: Female::3:1, Disease is more commonly seen in people with lower socio economic status group. 80% High socio economic class 20%. Discharging sinus is the commonest mode of presentation 72% and pain 72% and 84% pass history of perianal abscess was the presenting symptoms.

    BACKGROUND:Many small veins are called accessory, short hepatic veins in addition to the right, middle and left hepatic veins. The size of these veins varied from a pinhole to 1 cm; the size of inferior right hepatic veins (IRHVs) is thicker than that of short hepatic veins or more than 1 cm occasionally. Adults have a higher incidence rate of the IRHV. DATA SOURCES:A literature search of the PubMed database was conducted and research articles were reviewed. RESULTS:The size of IRHVs is related to the size of the right hepatic vein, i.e. the larger the diameter of the right hepatic vein, the smaller the diameter of the IRHVs, and vice versa. The IRHVs are divided into superior, medial and inferior groups, separately named the superior, medial and inferior right hepatic veins according to the position of the IRHV entering the inferior vena cava. The superior right hepatic vein mainly drains the superior part of segmentⅦ, and the medial right hepatic vein drains the middle part of segmentⅦ. A thicker IRHV mainly drains segmentⅥ and the inferior part of segmentⅦ and a thinner IRHV drains the inferior part of segmentⅤ. CONCLUSIONS:The clinical signiifcance of these studies on IRHVs is varied: (1) Hepatic caudate lobe resection could be introduced after study on the veins of that lobe. (2) It is very important to identify the draining region of the IRHV for guiding hepatic segmentectomy. The postero-inferior area of the right lobe can be preserved along with the hypertrophic IRHV even if the entire main right hepatic vein is resected during segmentectomy ofⅦ andⅧwith right hepatic vein resection for patients with primary liver cancer. (3) The ligation of the major hepatic vein for the treatment of juxtahepatic vein injury is recommended because of severe hemorrhagic shock and dififculty in

    LY 195448 is a phenethanolamine that has shown anti-tumour activity in a range of murine tumour models, although its mechanism of action is unknown. Pre-clinical studies have indicated the absence of "standard" side effects such as myelosuppression and gastrointestinal toxicity. The present phase I trial was carried out in nine patients at doses ranging up to 133 mg/m2. The major toxicities up to that dose were mild, reversible hypotension, tachycardia and tremor. No haematological or biochemical toxicity was observed. Murine pharmacokinetics were assessed at a dose level that was effective in experimental tumours and compared with human pharmacokinetic parameters derived from this study. The results indicated the clinical possibility of reaching peak drug levels associated with experimental activity. However, no responses were seen at the doses used. This study was terminated prior to its completion due to an unexplained loss of activity against murine tumours since September 1987. No significant loss of the in vitro anti-mitotic activity originally reported by Boder et al. [3] was observed. Possible reasons for the apparent loss of in vivo activity have been intensively investigated, but no cause has been determined. Therefore, clinical trials with LY 195448 have been discontinued.

    The in vitro activity of ceftriaxone against 437 clinical isolates of gram-negative bacilli was determined. Ceftriaxone was found to have high in vitro activity against Enterobacteriaceae, with the exception of Enterobacter cloacae. Ceftriaxone was only minimally active against Pseudomonas aeruginosa and Acinetobacter calcoaceticus. We evaluated the clinical efficacy and toxicity of ceftriaxone in 55 adult patients. Bacterial infection was confirmed by the isolation of etiological bacteria in...

    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.
