    Full Text Available Abstract Background The mental health of the Armed Forces is an important issue of both academic and public interest. The aims of this study are to: a assess the prevalence and risk factors for common mental disorders and post traumatic stress disorder (PTSD symptoms, during the main fighting period of the Iraq War (TELIC 1 and later deployments to Iraq or elsewhere and enlistment status (regular or reserve, and b compare the prevalence of depression, PTSD symptoms and suicidal ideation in regular and reserve UK Army personnel who deployed to Iraq with their US counterparts. Methods Participants were drawn from a large UK military health study using a standard two phase survey technique stratified by deployment status and engagement type. Participants undertook a structured telephone interview including the Patient Health Questionnaire (PHQ and a short measure of PTSD (Primary Care PTSD, PC-PTSD. The response rate was 76% (821 participants. Results The weighted prevalence of common mental disorders and PTSD symptoms was 27.2% and 4.8%, respectively. The most common diagnoses were alcohol abuse (18.0% and neurotic disorders (13.5%. There was no health effect of deploying for regular personnel, but an increased risk of PTSD for reservists who deployed to Iraq and other recent deployments compared to reservists who did not deploy. The prevalence of depression, PTSD symptoms and subjective poor health were similar between regular US and UK Iraq combatants. Conclusion The most common mental disorders in the UK military are alcohol abuse and neurotic disorders. The prevalence of PTSD symptoms remains low in the UK military, but reservists are at greater risk of psychiatric injury than regular personnel.

    2009-06-01

    Full Text Available Abstract Background Data protection is important for all information systems that deal with human-subjects data. Grid-based systems – such as the cancer Biomedical Informatics Grid (caBIG – seek to develop new mechanisms to facilitate real-time federation of cancer-relevant data sources, including sources protected under a variety of regulatory laws, such as HIPAA and 21CFR11. These systems embody new models for data sharing, and hence pose new challenges to the regulatory community, and to those who would develop or adopt them. These challenges must be understood by both systems developers and system adopters. In this paper, we describe our work collecting policy statements, expectations, and requirements from regulatory decision makers at academic cancer centers in the United States. We use these statements to examine fundamental assumptions regarding data sharing using data federations and grid computing. Methods An interview-based study of key stakeholders from a sample of US cancer centers. Interviews were structured, and used an instrument that was developed for the purpose of this study. The instrument included a set of problem scenarios – difficult policy situations that were derived during a full-day discussion of potentially problematic issues by a set of project participants with diverse expertise. Each problem scenario included a set of open-ended questions that were designed to elucidate stakeholder opinions and concerns. Interviews were transcribed verbatim and used for both qualitative and quantitative analysis. For quantitative analysis, data was aggregated at the individual or institutional unit of analysis, depending on the specific interview question. Results Thirty-one (31 individuals at six cancer centers were contacted to participate. Twenty-four out of thirty-one (24/31 individuals responded to our request- yielding a total response rate of 77%. Respondents included IRB directors and policy-makers, privacy and

  5. Bonus systems and their effects on safety: an interview-based pilot study at the Swedish nuclear power plants

    International Nuclear Information System (INIS)

    The aim of this pilot study has been to describe and analyse potential effects on safety-related behaviour and risks associated with the bonus systems currently used at Swedish nuclear plants. To this end and in order to establish a frame of reference several theories on motivation were consulted regarding the relevance of monetary rewards. In addition empirical evidence on effects upon behaviours in general and safety behaviours in particular was taken into consideration, as well as a systems and a rationalist perspective on organisations. The resulting frame of reference was used for a descriptive mapping of the bonus systems and for the formulation of a semi-structured interview schedule intended to capture the experiences of those concerned by the systems. A total of 15 interviews were performed with staff of different functions and organisational positions. Results of the study do not indicate any negative effects on safety-related behaviours. Rather they indicate that safety-behaviours may be promoted insofar as bonus rewards are linked to performance goals concerning safety. All of the bonus-systems may be characterised as low in incentive intensity, i.e. produce small effects on motivation and performance. Still, as the systems differ in design and in the way they are perceived, they also represent different challenges in order to function more efficiently as parameters

    Background Bipolar affective disorder has a high rate of comorbidity with a multitude of psychiatric disorders and medical conditions. Among all the potential comorbidities, co-existing anxiety disorders stand out due to their high prevalence. Aims To determine the lifetime prevalence of comorbid anxiety disorders in bipolar affective disorder under the care of psychiatric services through systematic review and meta-analysis. Method Random effects meta-analyses were used to calculate the lifetime prevalence of comorbid generalised anxiety disorder, panic disorder, social anxiety disorder, specific phobia, agoraphobia, obsessive compulsive disorder and posttraumatic stress disorder in bipolar affective disorder. Results 52 studies were included in the meta-analysis. The rate of lifetime comorbidity was as follows: panic disorder 16.8% (95% CI 13.7–20.1), generalised anxiety disorder 14.4% (95% CI 10.8–18.3), social anxiety disorder13.3% (95% CI 10.1–16.9), post-traumatic stress disorder 10.8% (95% CI 7.3–14.9), specific phobia 10.8% (95% CI 8.2–13.7), obsessive compulsive disorder 10.7% (95% CI 8.7–13.0) and agoraphobia 7.8% (95% CI 5.2–11.0). The lifetime prevalence of any anxiety disorders in bipolar disorder was 42.7%. Conclusions Our results suggest a high rate of lifetime concurrent anxiety disorders in bipolar disorder. The diagnostic issues at the interface are particularly difficult because of the substantial symptom overlap. The treatment of co-existing conditions has clinically remained challenging.

  20. Clinical Studies with Epothilones

    Science.gov (United States)

    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.

    Full Text Available INTRODUCTION : Early diagnosis and severity evaluation on patients with acute pancreatitis are very important due to its potential morbidity and mortality. Given the wide spectrum of disease seen, the care of patients with pancreatitis must be highly individualized. Sev eral clinical, laboratory and radiologic factors and many scoring systems have been proposed for outcome prediction. AIMS AND OBJECTIVES: To study the symptomatology, clinical presentation and management in pancreatitis . To study the severity of acute panc reatitis according to Glasgow Scale . METHODS: Present study includes consecutive 38 patients hospitalized in CSI Holdsworth Memorial Hospital over the period of 2 years. All patients were thoroughly investigated and were stratified according to the Glasgow criteria. Data was collected on complications, investigations and interventions undertaken, outcome, duration of stay in hospital and ICU. STATISTICAL ANALYSIS USED: Descriptive, Chi square tests, Crosstabs (Contingency coefficient analysis . RESULTS : Mean age of presentation in our study was 43.1 years. There was a male predominance accounting for 68.4% compared to 31.6% females. Alcohol was the main etiological factor in about 50% of the patients. Sensitivity to S. amylase was about 100%. Accuracy of USG abdomen in diagnosing pancreatitis was about 88.5%. Ascitis was the commonest complication seen in 13.2%. Mean duration of hospital stay was 6.2 days. The patient were stratified according to Glasgow scoring system into mild (0 - 3 and severe (>3 panc reatitis. In our study 32 people were graded with mild pancreatitis, all improved and in 6 people who were graded with severe pancreatitis, 83.3 % improved and 2.6% expired because of complications. Test statistics showed Contingency coefficient 0.355 and P 0.019 (NS. CONCLUSION : Glasgow scoring system remains a valid predicting system for the outcome in patients with acute pancreatitis.

  12. 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.

    Directory of Open Access Journals (Sweden)

    L Subha

    2015-01-01

    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.

  4. Contact dermatitis to hair dyes in a Danish adult population: an interview-based study

    DEFF Research Database (Denmark)

    Søsted, H; Hesse, U; Menné, T;

    2005-01-01

    BACKGROUND: Contact allergy to hair dye ingredients is a well-known entity seen both in consumers using hair dyes and among hairdressers with occupational contact dermatitis. Surveys show that consumers with even severe adverse skin reactions to hair dyes only rarely contact the healthcare services....... The frequency of hair dye-induced skin reactions in the consumer population is unknown. OBJECTIVES: An epidemiological investigation with the aim of establishing the proportion of hair dye-induced skin reactions was performed in a population-based sample. METHODS: A representative random sample (n...... = 4000) was taken of the Danish adult population. Personal interview questions were asked regarding adverse skin reactions to hair dyes, either compatible with a classical allergic eczematous reaction with redness, scaling and itching or a severe allergic reaction with oedema of the forehead and face...

    The Caspian seal (Pusa caspica) has declined by more than 90% since 1900 and is listed as endangered by IUCN. We made the first quantitative assessment of Caspian seal by-catch mortality in fisheries in the north Caspian Sea by conducting semi-structured interviews in fishing communities along the coasts of Russia (Kalmykia, Dagestan), Kazakhstan and Turkmenistan. We recorded a documented minimum by-catch of 1,215 seals in the survey sample, for the 2008-2009 fishing season, 93% of which occurred in illegal sturgeon fisheries. Due to the illegal nature of the fishery, accurately quantifying total fishing effort is problematic and the survey sample could reflect less than 10% of poaching activity in the north Caspian Sea. Therefore total annual by-catch may be significantly greater than the minimum documented by the survey. The presence of high by-catch rates was supported independently by evidence of net entanglement from seal carcasses, during a mass stranding on the Kazakh coast in May 2009, where 30 of 312 carcasses were entangled in large mesh sturgeon net remnants. The documented minimum by-catch may account for 5 to 19% of annual pup production. Sturgeon poaching therefore not only represents a serious threat to Caspian sturgeon populations, but may also be having broader impacts on the Caspian Sea ecosystem by contributing to a decline in one of the ecosystem's key predators. This study demonstrates the utility of interview-based approaches in providing rapid assessments of by-catch in illegal small-scale fisheries, which are not amenable to study by other methods.

    2016-03-01

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

    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

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

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

    FES-I has been designed to assess fear of falling (FoF). The purpose of this study was to establish the Persian-language version of the FES-I and to assess its psychometric properties under different modes of administration: self-report and interview-based. Participants included 191 elderly people aged over 60 who were mostly community dwelling. With an interval of 14 days, 97 volunteers completed the questionnaire in the retest session. To evaluate the construct validity, we assessed the ability of the FES-I to discriminate people based on gender, level of education, number of falls and FoF. The correlation with the Short Form of Health Survey (SF-36), Timed Up and Go (TUG) and Functional Reach Test (FRT) was also determined to test validity. Internal consistency was excellent in both self-report (0.93) and interview (0.92) versions. All intra-class correlations (ICCs) were above 0.70 with the highest reliability obtained for the condition where the interview based FES-I was used in both test and retest sessions. The strength of correlation between the FES-I and TUG varied based on mode of administration: moderate for interview and high for self-report mode. The FES-I had a higher correlation with the SF-36 subscales of physical health than subscales of mental health. The FES-I had the ability to discriminate the participants based on gender, educational level, and number of falls and FoF. In conclusion, both interview and self-report versions of the FES-I demonstrated acceptable measurement properties to assess FoF in Iranian elderly persons. PMID:23830993

    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.

    In the present study osteoradionecrosis which had developed after radiotherapy for malignant tumor was studied clinically and therapeutically and the following results were obtained. 1. The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5. As the method of treatment, sequestrectomy was performed in 14 of 19 cases of the limited area type and 4 of 11 cases of the wide range type and excision of the jaws in 4 cases. 6. Hyperbaric oxygen therapy was carried out in 3 cases and had good effect. (J.P.N.).

The subjects were 28 patients with squamous cell carcinoma and 2 patients with adenoid cystic carcinoma aged 38 to 72. The ratio of male: female was 3.3 : 1. The time of manifestation was 1 month-14 years after irradiation. The main symptoms were pain and exposed bone mainly in the region of mandibular molar tooth. 2. Osteoradionecrosis was observed in 10 cases supposed to be induced by tooth extraction but also in 5 edentulous cases. 3. When the osteoradionecrosis cases were classified into limited area type and wide range type on the basis of clinical findings. X-ray of the jaws showed the presence of bone resorption and induration together in many wide range type cases. 4. Scintigram of bone showed widespread accumulation of radiation even in clinically limited area type, and the picture of some loss of bone and the intensity of the accumulation were considered to be extremely useful as an index in making therapeutical plans and decisions on the prognosis of tumor of the jaws. 5. As the method of treatment, sequestrectomy was performed in 14 of 19 cases of the limited area type and 4 of 11 cases of the wide range type and excision of the jaws in 4 cases. 6. Hyperbaric oxygen therapy was carried out in 3 cases and had good effect. (J.P.N.)

    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...

Results: The male and female were in the ratio of 2.21: 1. Right eye ocular traumas were more than left ones. Ocular penetrating trauma was 83.12% and blunt trauma 12.99%. 41 cases (53.25%) were injured by themselves while 33 cases by others. 90.91% patients came from the countryside.Conclusion: The rate of blindness of children with ocular trauma could be reduced by prompt treatment. The study indicated that ocular trauma preventive publicity should be faced in the countryside in order to improve the understanding of the severity of ocular trauma and treat it as a social problem.

  17. A clinical study of papular urticaria

    International Nuclear Information System (INIS)

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

    2014-06-01

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

    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

  20. Clinic-Radiological Study of facial paralysis

    International Nuclear Information System (INIS)

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

  2. 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.

  3. Clinical and neuroradiological studies on internuclear ophthalmoplegia

    International Nuclear Information System (INIS)

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

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

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

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

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

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

  9. Experimental and clinical studies on CT lymphography

    International Nuclear Information System (INIS)

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

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

    Full Text Available INTRODUCTION: The scrotum is a cutaneous bag containing the right and left testis, the epididymis and the lower parts of the spermatic cords. 1 Scrotal swellings are the commonest swellings affecting both children and adults. Though these swellings are frequently encountered, many times correct dia gnosis is not made and testis has been sacrificed . It also affects the physical wellbeing of the patient, is rather a mental agony for him. Most of the times, patients hesitate to come early and may come with late complications. AIMS AND OBJECTIVES OF THE STUDY: 1. To determine and confirm various etiological aspects of different swellings of scrotum. 2. To study various modes of presentations, relative incidence and diagnostic procedures for swellings of scrotum. 3. To study the various techniques and proc edures done . MATERIALS AND METHODS: STUDY DESIGN: Prospective Clinical Study . STUDY AREA: Sri Venkateswara Medical College , Tirupathi . SOURCE OF DATA: The material for the present study is collected from the patients who present to the Out Patient Department of Surgery, Sri Venkateswara Medical College with swelling in the scrotal region fulfilling the inclusion criteria. SAMPLE SIZE: 100 patients fulfil ling the inclusion criteria . METHOD OF COLLECTION OF DATA: Detailed history taking , Complete clinical examination , Appropriate Investigations Blood & Urine Examination, USG , Performing surgery for the indicated cases & Operative findings were recorded. INC LUSION CRITERIA: Patients aged between 13 to 60yrs. Cystic swellings from the testes & its coverings, epididymis, spermatic cord & from scrotal skin. EXCLUSION CRITERIA : Cystic inguino - scrotal swellings. Patients aged above 60. RESULTS & CONCLUSIONS: Major ity of the patients with swelling of the scrotum belonged to the 31 - 40 years of age group (50% followed by 41 - 50 years (18% and 21 - 30 years (12%. Scrotal swelling was the common mode of presentation (60%. Right side was

  12. 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

  13. Uremic pruritus. Clinical and experimental studies.

    Ståhle-Bäckdahl, M

    1989-01-01

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

  14. Clinical application of cerebral dynamic perfusion studies

    International Nuclear Information System (INIS)

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

    Full Text Available INTRODUCTION Ileal perforation is a common problem seen in tropical countries, the commonest cause being typhoid fever. In western countries the causes are malignancy, trauma and mechanical aetiology, in the order of frequency.1,2,3 Over the years a definite changing trend has been observed in ileal perforations both in terms of causes, treatment and prognosis. Better antibiotics, aggressive surgery and the elimination of conservative treatment, better preoperative and postoperative care have all significantly contributed to the improvement in patient outcome.4,5 But still cases of ileal perforation cause a significant morbidity and mortality that persists despite the significant changes in health care over the years. AIMS AND OBJECTIVES To study the aetiology, presentation, management outcome and the factors influencing prognosis and outcome in ileal perforations. MATERIAL & METHODS Study Setting S. V. Medical College, Department of General Surgery, Tirupati. Study Period Patients attending S. V. Medical College, Department of General Surgery with perforation during the period from November 2012 to October 2015. Inclusion Criteria Patients between age group of more than 14 years presenting with pain abdomen and who are diagnosed to have ileal perforation in the intra operative period are selected. Exclusion Criteria Patients with peritonitis due to other causes like gastric, duodenum or large bowel perforation are excluded. Study Method The present study is a prospective study done on 28 patients of ileal perforation due to typhoid complication, nonspecific and traumatic perforations. History, clinical examination, investigations, operative findings, post-operative complications were recorded. In patients with non-traumatic perforations Widal test was done. CONCLUSION Typhoid fever and traumatic aetiology are the most common cause of Ileal perforation, followed by TB. Patients are more of male gender and are in reproductive age group. Widal

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

    Full Text Available Extrapulmonary tuberculosis constitutes about 10% of all cases of tuberculosis, and cutaneous tuberculosis makes up only a small proportion of these cases. Despite prevention programs, tuberculosis is still progressing endemically in developing countries. Commonest clinical variant of cutaneous tuberculosis in our study was tuberculous verrucosa cutis (TBVC seen in 46.66% patients followed by Lupus vulgaris seen in 33.33% patients followed by scrofuloderma (13.33%, papulonecrotic tuberculide (6.66%. The commonest site of involvement was upper limbs seen in 46.66% patients followed by lower limb seen in 20% patients, face, neck, inguinal region, axilla, chest in 6.66% and generalized pappilary eruptions in 6.66% patients. Maximum percentage of patients (53.3% had duration of cutaneous tuberculosis between 1-3 years followed by 33.33% between 1-6 months, 6.66% had duration of cutaneous tuberculosis between 7-12 months, and rest 6.66% had duration between 4-6 years. The commonest histopathological feature in our study was tuberculoid granuloma with epithelioid and Langhans giant cells seen in 70% patients, hyperkeratosis was seen in 13.33% patients and AFB bacilli were seen in 6.66% patients.

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

  20. Clinical study of the stunned myocardium

    International Nuclear Information System (INIS)

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

    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.

    Full Text Available NTRIDUCTION : Stroke is one of the important causes of morbidity and mortality all over the world. Incidence of stroke steadily increases with age. Experts are concerned of the emerging stroke epidemic in India. Stroke affecting the young has potentially devastating consequence son the individual and his family. Certain risk factors are unique to the young. I t needs more studies for identification and modification of risk factors. The study aims to evaluate clinical features, risk factors, etiology and mortality of stroke in young patients. METHODS : 74 young patients satisfying the inclusion criteria were included in this study. A detailed history was taken from young stroke patients, systemic examination and required investigations were done. Data was collected in standardized proforma and analysed. RESULTS: Stroke in young accounts for 7.95% of stroke cases of all age groups. The mean age of the patients was 34.66 ± 7.48 years. Among 74 patients, 47(63.51% were male and 27(36.49% were female. Seizures, decreased consciousness, speech involvement and motor deficit were observed in 33.78%, 44.59%, 22.97% and 100% of cases respectively. 82.43% patients had ischemic and 17.57% patients had hemorrhagic stroke. Among ischemic stroke, large artery atherosclerosis was 16.21%, tuberculous meningoencephalitis with vasculitis was 16.21%, lacunar stroke was 10.81%, CVT was 10.81% and cardio embolic stroke was 6.76%.

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

  8. Abnormal neuronal migration: radiologic-clinic study

    International Nuclear Information System (INIS)

    We present our experience in 18 pediatric patients with abnormal neuronal migration. Seven cases of heterotopia of the gray matter, 7 agyria-pachygyria complexes, 1 case of polymicrogyria, 2 cases of schizencephaly and 1 case of hemimegalencephaly were diagnosed by means of ultrasonography, computed tomography and magnetic resonance. The clinical picture was reviewed in each case, with special attention to the occurrence of convulsions, psycho motor development and visual changes. In general, the greater the morphological change, the greater the neurological involvement in these patients. However, the two cases of schizencephaly presented mild clinical expression. Magnetic resonance increases the diagnostic yield in neuronal migration disorders. Nevertheless, either ultrasonography or, especially, computed tomography is useful as a first diagnostic approach in these malformative disorders. (Author)

    Congenital myopathies (CMs), a group of relatively non-progressive disorders presents with weakness and hypotonia of varying severity, morphologically recognized by specific structural abnormalities within the myofiber. This report presents the clinical and Histopathological features of 40 patients with CMs. Centronuclear myopathy was the commonest (40%) followed by congenital fiber type disproportion (37.5%). Other less common CMs included: myotubular myopathy (5%), nemaline myopathy (5%), central core disease (5%), multicore disease (2.5%) and congenital myopathy with tubular aggregate (5%). Immunolabeling to desmin corresponded to morphological changes within the myofibers while vimentin was negative in all the patients.

  12. Frontotemporal dementia; clinical-radiological study

    International Nuclear Information System (INIS)

    Frontotemporal dementia is the third most common degenerative condition (after Alzheimer Disease and Lewy Body Disease) of the brain. It occurs predominantly after the age of 40 and usually before the age of 65, with equal incidence in men and women. Unspecific behavioral symptoms often lead to misdiagnosis and FTD remains undetected. As in other degenerative dementias, there is no specific tissue marker; therefore, the diagnosis is established in vivo on the basis of clinical and radiological examinations. Structural and functional neuroimaging modalities are most useful in detection and differentiation of FTD as the findings are specific enough to be considered as criteria, based on which the diagnosis of this disorder can be established.

    Objective: To observe the clinical effect of guava leaf (GL) in treating infantile rotaviral enteritis.Methods: Sixty-two patients of rotaviral enteritis were randomly divided into the treated group treated with GL and the control group treated with Gegen Qinlian Decoction. The time for ceasing diarrhea, content of Na+ in blood, content of Na+ and glucose in stool, and the rate of negative conversion of human rotavirus antigen (HRVA) were observed.Results: The 3-day recovery rate in the treated group (87.1%) was significantly higher than that in the control group (58.1%, P<0.05). The time of ceasing diarrhea in the treated group (25.1±9.5 hrs) was significantly shorter than that in the control group (38.7±15.2 hrs, P<0.01). Moreover, content of Na+ and glucose in stool were reduced obviously in the treated group but not in the control group; and negative conversion rate of HRVA in the former group also got better than that in the latter group (87.1% vs 58.1%, P<0.05). Consequently, the effect of GL was superior to that of the control significantly.Conclusion: GL has good curative effect on infantile rotaviral enteritis.

    Studies in classical psychiatry and psychoanalysis have reduced perversions to pathological phenomena, by lessening the moral criterion progressively. The applying of a comprehensive method of study of acquired perversions incites to consider various levels of observation. Henceforth properties common to each of these levels appears permitting thus to isolate a general process of perversion. This process, which keeps undeniable links with mental pathology, must however be differentiated, for it is not necessarily to be assimilated or reduced to the latter. Besides, it entails notable consequences on the social and cultural level. PMID:1233902

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

    Methods: The study is undertaken with forty cases with ages ranging from new borne to 20 yrs. Out of these 40 cases eight cases are below one year. In these cases physical examination is correlated with ultrasonography and chromosomal analysis. Results: In chromosomal analysis three persons out of forty cases were mosaics with 45, XO/46, twenty one cases who showed the chromosomal pattern as 46, XY mostly showed with no mullarian reminents. On examination palpable gonads were found in labio-scrotal sacs in seventeen cases. One of these cases was reared as girl found cytogenetically as 46, XY with the ultrasonographic impression as small uterus with no ovaries. Nineteen cases who with ambiguous genitalia showed the chromosomal pattern as 46, XX one out of these cases showed enlargement of the breast, and on examination of external genitalia found enlarged clitoris with labiamajora and minora. The child was brought up as male. Genitogram showed the absence of uterus. Conclusions: Chromosomal studies with ultrasonography can help in rearing a child male or female in young generation by surgical and Hormonal therapy. This prevents many problems in later life. This fact should be advertised openly in the public so that illiterate people should be alert. [Int J Res Med Sci 2015; 3(12.000: 3743-3748

    Plasma levels of cholesterol, HDL cholesterol (HDL chol), LDL cholesterol (LDL chol), triglycerides, Al apoprotein and B apoprotein were studied in 73 patients receiving 500 mg aminoglutethimide (AG)/day and 40 mg hydrocortisone/day for advanced breast cancer. These dosages were done before treatment and then repeated during AG therapy. When all patients were considered together, a significant increase of cholesterol, HDL chol, LDL chol and Al apoprotein was noted. If one considers two groups of patients: group A (where cholesterol and triglycerides plasma levels were normal before treatment) and group B (where cholesterol and/or triglycerides plasma levels were high before treatment), it appears that variations differ in both groups. In group A patients we found an increase in cholesterol, chol LDL, B apoprotein and to a lesser extent Al apoprotein plasma levels. In group B patients there was an increase in cholesterol, HDL chol and Al apoprotein plasma levels. PMID:3924146

  18. Clinical study of cardiogenic cerebral embolism

    International Nuclear Information System (INIS)

    In order to investigate the distribution of lesion size and to determine the background factors responsible for large infarcts, we examined CT findings in 88 consecutive patients with acute cardiogenic cerebral embolism of the internal carotid arterial system. Lesion size was determined by brain CT, and expressed as the 'infarct index'. The typical CT finding was a sharply marginated lesion in the cortex corresponding to the occluded arterial territory, accompanied by mass effect. Over half of the cases showed an infarct index of 20% or less. Most cases had small lesions, with substantially fewer cases having large infarcts. The lack of large infarcts was attributable to early recanalization of the occluded artery. Several background factors were implicated in the large infarcts, including elevated hematocrit, fibrinogen, arterial blood pressure, cardiothoracic ratio (as seen in chest X-rays), and a shortening of activated partial thromboplastin time (APTT). Factors implicated in the formation of a large embolus included increased blood viscosity and coagulability (caused by dehydration), and a hypertension-induced shift of the lower limit of autoregulation to a higher level. Further study is needed to determine whether such changes arise as the cause or the effect of a cerebral embolism. (author)

  19. Roentgenological and clinical studies on radiation colitis

    International Nuclear Information System (INIS)

    Fifty-six patients with radiation induced colitis in two institutes, 20 irradiated externally and 36 irradiated both externally and intracavitarily, were studied. The severity of radiation injuries was classified into 4 grades according to roentgenological and romanoscopical findings. Based on the charts of TAO system, radiation doses were calculated at the anterior rectal wall where maximum absorption dose of the colon was expected. The most frequent complaint was bloody stool which started about one year after irradiation. Onset of subjective symptoms was significantly delayed in milder cases (Grade II) than in more severe groups (Grades III, IV). Only minor injuries (Grade I) were noted in most of the externally irradiated, whereas more severe findings of radiation colitis were frequent in cervical cancer patients irradiated both intracavitarily and externally. The most common site involved in cervical cancer patients was the anterior colonic wall at the recto-sigmoid junction just behind the uterine cervix. In terms of relationship between time dose fractionation (TDF) and severity of radiation colitis, it was found that remarkable radiation injuries (Grades III, IV) occurred in the group of TDF value of 117 or more (more than 7500 rad). Therefore the author recommend the TDF value of 110 or less in cervical cancer cases with radiation therapy to keep radiation injury under Grade II. (author)

  20. Enhancing Patient Safety Using Clinical Nursing Data: A Pilot Study.

    2016-01-01

    To enhance patient safety from falls, many hospital information systems have been implemented to collect clinical data from the bedside and have used the information to improve fall prevention care. However, most of them use administrative data not clinical nursing data. This necessitated the development of a web-based Nursing Practice and Research Information Management System (NPRIMS) that processes clinical nursing data to measure nurses' delivery of fall prevention care and its impact on patient outcomes. This pilot study developed computer algorithms based on a falls prevention protocol and programmed the prototype NPRIMS. It successfully measured the performance of nursing care delivered and its impact on patient outcomes using clinical nursing data from the study site. Results of the study revealed that NPRIMS has the potential to pinpoint components of nursing processes that are in need of improvement for preventing patient from falls. PMID:27332171

    Full Text Available Objective: To analyze the correlation between quality of life, symptoms, and cognition assessed by the interview-based Schizophrenia Cognition Rating Scale (SCoRS. Methods: Seventy-nine outpatients diagnosed with schizophrenia were evaluated with the Quality of Life Scale – Brazilian version (QLS-BR, the SCoRS, and symptoms scales (Positive and Negative Syndrome Scale [PANSS]. After determining the potential explanatory variables using Spearman’s correlation and Student’s t test results, we ran simple, multivariate, and decision-tree regression analyses to assess the impact of SCoRS and PANSS ratings on mean overall quality of life. Results: Cognitive deficits and negative symptoms were the best predictors of quality of life. A low degree of negative symptoms (PANSS negative < 11 was a strong predictor of better quality of life (QLS ∼ 75, regardless of SCoRS rating. Among participants with more severe negative symptoms, elevated cognitive impairment (interviewer SCoRS ∼ 44 was a predictor of worse quality of life (QLS ∼ 44. Conclusions: Cognitive impairment determined by interview-based assessment seems to be a strong predictor of quality of life in subjects with severe negative symptoms. These results support the usefulness of SCoRS for cognitive assessment that is relevant to the everyday life of patients with schizophrenia.

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

The nutritional status of the study participants was assessed using the Nutritional Risk Screening 2002 (NRS 2002 and micronutrient levels and routine biochemical parameters were tested within the first 24 h of the patient’s admission. The incidence of zinc, selenium, thiamine, vitamin B6, vitamin B12 deficiency were 66.7% (n = 40, 46.6% (n = 29, 39.7% (n = 27, 35.3% (n = 24, 14.1% (n = 9, respectively. Selenium levels were significantly higher in patients with urinary tract infections, but lower in soft tissue infections. Copper levels were significantly higher in patients with soft tissue infections. In the Cox regression models, lower albumin, higher serum lactate dehydrogenase levels and higher NRS-2002 scores were associated with increased death. Thiamine, selenium, zinc and vitamin B6 deficiencies but not chromium deficiencies are common in infectious disease clinics. New associations were found between micronutrient levels and infection type and their adverse clinical outcomes. Hypoalbuminemia and a high NRS-2002 score had the greatest accuracy in predicting death, systemic inflammatory response syndrome and sepsis on admission.

    Full Text Available For many students in the health sciences, including doctor of pharmacy (PharmD students, basic and clinical sciences often appear detached from each other. In the infectious disease field, PharmD students additionally struggle with mastering the diversity of microorganisms and the corresponding therapies. The objective of this study was to design an interdisciplinary project that integrates fundamental microbiology with clinical research and decision-making skills. The Emerging Microbe Project guided students through the identification of a microorganism via genetic sequence analysis. The unknown microbe provided the basis for a patient case that asked the student to design a therapeutic treatment strategy for an infected patient. Outside of lecture, students had two weeks to identify the pathogen using nucleotide sequences, compose a microbiology report on the pathogen, and recommend an appropriate therapeutic treatment plan for the corresponding clinical case. We hypothesized that the students would develop a better understanding of the interplay between basic microbiology and infectious disease clinical practice, and that they would gain confidence and skill in independently selecting appropriate antimicrobial therapies for a new disease state. The exercise was conducted with PharmD students in their second professional year of pharmacy school in a required infectious disease course. Here, we demonstrate that the Emerging Microbe Project significantly improved student learning through two assessment strategies (assignment grades and exam questions, and increased student confidence in clinical infectious disease practice. This exercise could be modified for other health sciences students or undergraduates depending upon the level of clinical focus required of the course.

    A working knowledge of common research study designs and their advantages and disadvantages is necessary for critical reading of the literature by clinicians. However, understanding study designs and related statistical methodologies may be perceived as being complex and difficult to execute. This review aims to provide a practical foundation for basic study designs and to help physicians identify pitfalls that commonly occur in clinical studies and their level of evidence. Topics covered include the pros and cons of observational versus prospectively controlled studies, case-control, cohort, randomized controlled studies, adaptive controlled trials and metaanalyses, and the role of matching in studies.

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

    2015-08-01

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

  2. Considerations for clinical pharmacology studies for biologics in emerging markets.

    Registration of innovative biologics in Emerging Markets (EMs) poses many opportunities and challenges. The BRIC-MT countries (Brazil, Russia, India, China, Mexico, and Turkey) that are the fastest growing markets and regulators in these countries have imposed certain requirements, including the need for local clinical studies, for registration of biologics. The regulatory landscape in these countries is rapidly evolving, which necessitates an up-to-date understanding of such requirements. There is growing evidence which suggests that race, after accounting for body weight differences, may not influence the pharmacokinetics of biologics to the same extent that it does for small molecules. Thus, the requirements for clinical pharmacology trials in EMs are driven mainly by regulatory needs set forth by local Ministry of Health. In addition to the clinical Phase I to III studies done in the global program that supports registration in large geographies, countries such as China require local single and multiple dose Phase I studies. Participating in global studies with clinical sites within their country may be sufficient for some markets, while other regulators may be satisfied with a Certificate of Pharmaceutical Product. This paper discusses the current requirements for registration of innovative biologics in key EMs. PMID:25707959

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

    The flamenco dancer acts on the floor like a drummer. The percussive footwork and vibration patterns created during dancing impose unusual demands on the musculoskeletal system. This study investigated the clinical and biomechanical aspects of this task. Using the electrodynogram and skin-mounted accelerometers, foot pressures as well as hip and knee vibrations were recorded in 10 female dancers after a thorough clinical evaluation. A health questionnaire was also distributed to 29 dancers. Foot pressures and acceleration data reveal the percussive nature of the dance. Some clinical findings, like calluses, are related to pressure distribution. Urogenital disorders, as well as back and neck pain, may be related to the vibrations generated by the flamenco dance form. The hip joint seems to absorb most of the impacts. "Vibration-pressure" diagrams are suggested as a useful tool for evaluating a dancer's biomechanical behavior, as well as the effect of floors and footwear on this behavior. PMID:3366430

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

    It is common for patients who are faced with physical or psychological suffering, particularly those in the advanced stages of a disease, to have some kind of wish to hasten death (WTHD). This paper reviews and summarises the current state of knowledge about the WTHD among people with end-stage disease, doing so from a clinical perspective and on the basis of published clinical research. Studies were identified through a search strategy applied to the main scientific databases. Clinical studies show that the WTHD has a multi-factor aetiology. The literature review suggests-perhaps in line with better management of physical pain-that psychological and spiritual aspects, including social factors, are the most important cause of such a wish. One of the difficulties facing clinical research is the lack of terminological and conceptual precision in defining the construct. Indeed, studies frequently blur the distinction between a generic wish to die, a WTDH (whether sporadic or persistent over time), the explicit expression of a wish to die, and a request for euthanasia or physician-assisted suicide. A notable contribution to knowledge in this field has been made by scales designed to evaluate the WTHD, although the problems of conceptual definition may once again limit the conclusions, which can be drawn from the results. Studies using qualitative methodology have also provided new information that can help in understanding such wishes. Further clinical research is needed to provide a complete understanding of this phenomenon and to foster the development of suitable care plans. PMID:20821377

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

    Full Text Available Background: Dermatophytoses refer to superficial fungal infection of keratinized tissues caused by keratinophilic dermatophytes. According to observations worldwide, dermatophytoses are the most common of the superficial fungal infections. It is common in tropics and may present in epidemic proportions in areas with high rates of humidity. Although common, the precise size of the problem defies measurement. Aims: The present study was undertaken to assess the clinical profile of dermatophytic infection and to identify the species of fungi that are prevalent in this region. Materials and Methods: A total of 100 patients clinically suspected for dermatophytoses were selected for the study. Direct microscopy in 10% potassium hydroxide (KOH and culture was done in each case. Results: Out of 100 patients, the maximum were seen in the age groups of 16-30 years. Tinea corporis was the most common clinical type (44.3% followed by tinea cruris (38.2%. Overall positivity by culture was 39% and by direct microscopy 96%. Conclusion: Trichophyton rubrum was the predominant species isolated (67.5% in all clinical types followed by Trichophyton mentagrophytes. Culturing the fungus may identify the species, but it is not essential for the diagnosis as it is not a sensitive test.

  19. Carbon ion radiotherapy. Clinical study and future prospect

    International Nuclear Information System (INIS)

    At present, most of the patients receiving carbon ion radiotherapy at National Institute of Radiological Sciences (NIRS) visit the clinic seeking this specific modality, and it is difficult to obtain consent for a randomized controlled study from these patients and it may be unnecessary to conduct a phase III trial. However, in selected tumors where the high-linear energy transfer (LET) benefit could be appreciated, we can participate in randomized studies. Finally, studies aimed at clarifying the usefulness of carbon ion radiotherapy and elucidating any advantages from hypo-fractionation should be considered. A multi-institutional prospective non-randomized concurrent phase II clinical trial is one such new approach, and it will be proposed not only to the Japanese, but also to the international community of particle therapy and radiation oncology.

    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.

    Full Text Available Background: Chronic actinic dermatitis (CAD, one of the immune mediated photo-dermatoses, comprises a spectrum of conditions including persistent light reactivity, photosensitive eczema and actinic reticuloid. Diagnostic criteria were laid down about 20 years back, but clinical features are the mainstay in diagnosis. In addition to extreme sensitivity to UVB, UVA and/or visible light, about three quarters of patients exhibit contact sensitivity to several allergens, which may contribute to the etiopathogenesis of CAD. This study was undertaken to examine the clinical features of CAD in India and to evaluate the relevance of patch testing and photo-aggravation testing in the diagnosis of CAD. Methods: The clinical data of nine patients with CAD were analyzed. Histopathology, patch testing and photo-aggravation testing were also performed. Results: All the patients were males. The average age of onset was 57 years. The first episode was usually noticed in the beginning of summer. Later the disease gradually tended to be perennial, without any seasonal variations. The areas affected were mainly the photo-exposed areas in all patients, and the back in three patients. Erythroderma was the presenting feature in two patients. The palms and soles were involved in five patients. Patch testing was positive in seven of nine patients. Conclusions: The diagnosis of CAD mainly depended upon the history and clinical features. The incidence of erythroderma and palmoplantar eczema was high in our series. Occupation seems to play a role in the etiopathogenesis of CAD.

    2004-01-01

    When clients and health care providers differ in their understanding of what is right or wrong, an ethical dilemma may arise. Such dilemmas occur in everyday clinical practice. Health care providers have the professional responsibility to analyze these dilemmas. A clinical case study of an ethical dilemma that occurred in a cross-cultural context is examined. The language of the client and provider differed, and no interpreter service was available. Given these conditions, the provider's ethical dilemma was whether, and if so how, to give safe, satisfying care that respected the needs of a client with limited English proficiency. Measuring the morality of the provider's decisions and actions using Rawls' ethical theory of social justice finds deficits. A 10-step Bioethical Decision-Making Model by Thompson is used to demonstrate one method for analyzing the moral dimension of a clinical scenario focusing on the decisions and actions taken by a midwife. Scrutinizing ethically challenging clinical encounters will result in better understanding of the moral dimensions of practice. PMID:15134678

    Full Text Available Tinea capitis is a common condition seen by clinician in all setting through out the world. Several investigations of the various superficial mycosewere carried out in Egypt, but they were mainly confined to urban areas. In the present work, the predominant species causing dermatophtosis in Assuit Governorate were investigated, this is represented in rural and partially suburban communities. A clinical and mycological study was done for hundred patients attending the Dermatology Out-patient Clinic in Al- Azhar University Hospital in Assuit City. The ages of patient ranged from 3 to 20 years . 60% of cases were between 6-10 years of ages. Males were affected more than females in a ratio of 3: 1 60% of cases were from rural areas. Positive history of contact with animals was present in 40%. The most common clinical variety was scaly type 55% followed by black dot 22%, kerion 20%, and lastly favus 3%. Direct microscopic examination was + ve in 80% of cases. Positive culture results were obtained in 90% of cases. The results indicated that Zoophilic dermatophytes was the predominant causative species in these regions. Five dermatophytes were identified namely: M.canis was the most frequently isolated organism from the clinical varieties of dermatophytosis (55% . followed by T. violaceum (20%. T. rubrum 12.8% , M. gypseum (10% and lastly T.soudanense (2.2%.

    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.)

    Making the transition from theory to practise easier in nursing education through simulation is widely implemented all over the world, and there is research evidence of the positive effects of simulation. The pre-understanding for this study is based on a definition of clinical competence as encountering, knowing, performing, maturing and developing, and the hypothesis is that these categories should appear in simulated situations. The aim of the study was to explore the forms and expressions of clinical competence in simulated situations and furthermore to explore if and how clinical competence could be developed by simulation. An observational hermeneutic study with a hypothetic-deductive approach was used in 18 simulated situations with 39 bachelor degree nursing students. In the situations, the scenarios, the actors and the plots were described. The story told was "the way from suffering to health" in which three main plots emerged. The first was, doing as performing and knowing, which took the shape of knowing what to do, acting responsibly, using evidence and equipment, appearing confident and feeling comfortable, and sharing work and information with others. The second was, being as encountering the patient, which took the shape of being there for him/her and confirming by listening and answering. The third plot was becoming as maturing and developing which took the shape of learning in co-operation with other students. All the deductive categories, shapes and expressions appeared as dialectic patterns having their negative counterparts. The study showed that clinical competence can be made evident and developed by simulation and that the challenge is in encountering the patient and his/her suffering. PMID:26763209

    Many studies have attempted to establish the genotype-phenotype correlation in Rett syndrome (RTT). Cardiorespiratory measurements provide robust objective data, to correlate with each of the different clinical phenotypes. It has important implications for the management and treatment of this syndrome. The aim of this study was to correlate the genotype with the quantitative cardiorespiratory data obtained by neurophysiological measurement combined with a clinical severity score. This international multicenter study was conducted in four European countries from 1999 to 2012. The study cohort consisted of a group of 132 well-defined RTT females aged between 2 and 43 years with extended clinical, molecular, and neurophysiological assessments. Diagnosis of RTT was based on the consensus criteria for RTT and molecular confirmation. Genotype-phenotype analyses of clinical features and cardiorespiratory data were performed after grouping mutations by the same type and localization or having the same putative biological effect on the MeCP2 protein, and subsequently on eight single recurrent mutations. A less severe phenotype was seen in females with CTS, p.R133C, and p.R294X mutations. Autonomic disturbances were present in all females, and not restricted to nor influenced by one specific group or any single recurrent mutation. The objective information from non-invasive neurophysiological evaluation of the disturbed central autonomic control is of great importance in helping to organize the lifelong care for females with RTT. Further research is needed to provide insights into the pathogenesis of autonomic dysfunction, and to develop evidence-based management in RTT. © 2016 Wiley Periodicals, Inc. PMID:27354166

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    2016-07-01

    The cystic fibrosis (CF) drug development pipeline promises many exciting new treatments for patients with CF, all which will require clinical studies to prove their benefits on CF lung disease. Historically many pivotal CF studies have used the Forced Expiratory Volume in 1s (FEV1) as the primary outcome measure, and after demonstrating significant improvements in the treatment group relative to placebo have led to regulatory approval of therapies for routine clinical care. Widespread implementation of these therapies has subsequently led to significant improvements in outcomes for patients with CF. While preserving lung function has obvious benefits to CF patients, as more patients maintain FEV1 in the normal range, it has become increasingly difficult to conduct clinical trials using FEV1 as the primary outcome measure. With multiple concurrent trials competing to enroll from the same pool of patients, there is a need for novel approaches to study end points as well as new physiological outcomes for CF therapeutic trials. In this review we will discuss some of the limitations of FEV1 in the current era of CF care, describe alternative physiological endpoints and outline areas for further research. PMID:27316663

  19. A Study on the Clinical Diagnosis of Hyperthyroidism

    International Nuclear Information System (INIS)

    To attain a simple and reliable method of evaluating the thyroid function the reliability of the clinical manifestation and the conventional thyroid function tests in diagnosing the hyperthyroidism was studied. The subjects included 184 patients with hyperthyroidism and 66 cases with euthyroidism, who were treated at the Thyroid Clinic, Seoul National University Hospital, from July 1971 through August 1972. The observed results were as follows: l. In the cases of hyperthyroidism, 19% of the patients were male and 81% female; in the cases of euthyroidism, 7. 6% of the patients were male and 92. 4% female. The majority of the patients were in 2nd to 4th decades of their lives. 2. There were objective signs clearly manifested in hyperthyroidism which were rare or absent in the euthyroid state. These clinical signs included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor, and warm skin. In the hyperthyroid state 91. 3% of the cases manifested two or more of the above signs, whereas in the euthyroid state no patients manifested any two of the above signs. 3. The most frequent complaints of the patients with thyroid disease were palpitation, weight low, increased appetite, heat intolerance, perspiration, hunger feeling; nervousness, exertional dyapnea, etc. There was no clear difference in the incidence of the symptoms between hyperthyroidism and euthyroidism. 4. In the diagnosis of hyperthyroidism, the reliability of thyroid function tests was as follows: T7 was 92. 4% reliable, 125IT3 resin uptake rate 91. 6% reliable, 131I thyroid uptake rate in 24 hrs. 89. 4% reliable, serum T4 level 85. 9% reliable and BMR 75. 5% reliable. Therefore the careful observation of the clinical manifestation of the disease is a simple and reliable way of making a correct diagnosis of either hyperthyroidism or euthymidism. 5. In hyperthyroidism there shows no correlationship between the results of the thyroid function test and clinical signs but a high BMR was

    Full Text Available Abstract Background We aimed to overview the current literature on eurythmy therapy (EYT which is an integral part of Anthroposophic Medicine. EYT can be described as a movement therapy in which speech movements are transposed into exercises which address the patient's capability to soul expression and strengthen his salutogenetic resources. Methods We searched several databases such as Cochrane, EMBASE, NCCAM, NLM, DIMDI, CAMbase, and Medline for case-control studies, cohort studies and randomised controlled trials on the treatment effects of EYT in a clinical setting. In a second search we included journal databases from Karger, Kluwer, Springer, Thieme, and Merkurstab archive. Results We found 8 citations which met the inclusion criterion: 4 publications referring to a prospective cohort study without control group (the AMOS study, and 4 articles referring to 2 explorative pre-post studies without control group, 1 prospective, non-randomized comparative study, and 1 descriptive study with a control group. The methodological quality of studies ranged in from poor to good, and in sample size from 5 to 898 patients. In most studies, EYT was used as an add-on, not as a mono-therapy. The studies described positive treatment effects with clinically relevant effect sizes in most cases. Conclusion Indications, study designs and the usage of additional treatments within the identified studies were quite heterogeneous. Despite of this, EYT can be regarded as a potentially relevant add-on in a therapeutic concept, although its specific relevance remains to be clarified. Well performed controlled studies on this unique treatment are highly recommended.

    2015-02-01

    Full Text Available Cancer is still one of the major causes of mortality in both developing and developed countries. At this time, in spite of intensive interventions, a large number of patients have poor prognosis. Therefore, the effort for finding new anticancer agents with better efficacy and lesser side effects has continued. According to the traditional recommendations and experimental studies, numerous medicinal plants have been reported to have anticancer effect. Also antiproliferative, proapoptotic, antimetastatic and antiangiogenic effects of several phytochemicals have been shown with in vitro experiments or animal studies. However, only a small number of them were tested in cancerous patients and limited evidence exists on their clinical effectiveness. Also, regarding some phytochemicals, only beneficial effects on cancer-related symptoms or on quality of life have been reported and no positive results exist on their antitumor actions. In this review we focus on phytochemicals that their beneficial effects on various types of cancer are supported by clinical trials. Based our literature search, curcumin, green tea, resveratrol and Viscum album had satisfactory instances of clinical evidence for supporting their anticancer effects. The main findings on these phytochemicals are summarized and discussed.

    2016-08-01

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

  4. Clinical and neurological study of women with precatamenial epilepsy

    International Nuclear Information System (INIS)

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

  5. Updates on clinical studies of selenium supplementation in radiotherapy

    International Nuclear Information System (INIS)

    To establish guidelines for the selenium supplementation in radiotherapy we assessed the benefits and risks of selenium supplementation in radiotherapy. Clinical studies on the use of selenium in radiotherapy were searched in the PubMed electronic database in January 2013. Sixteen clinical studies were identified among the 167 articles selected in the initial search. Ten articles were observational studies, and the other 6 articles reported studies on the effects of selenium supplementation in patients with cancer who underwent radiotherapy. The studies were conducted worldwide including European, American and Asian countries between 1987 and 2012. Plasma, serum or whole blood selenium levels were common parameters used to assess the effects of radiotherapy and the selenium supplementation status. Selenium supplementation improved the general conditions of the patients, improved their quality of life and reduced the side effects of radiotherapy. At the dose of selenium used in these studies (200–500 μg/day), selenium supplementation did not reduce the effectiveness of radiotherapy, and no toxicities were reported. Selenium supplementation may offer specific benefits for several types of cancer patients who undergo radiotherapy. Because high-dose selenium and long-term supplementation may be unsafe due to selenium toxicity, more evidence-based information and additional research are needed to ensure the therapeutic benefits of selenium supplementation

  6. Fibrin related antigens: assay development, clinical and kinetic studies

    International Nuclear Information System (INIS)

    This thesis describes an assay which is able to measure and to determine the proportions of fibrin- and fibrinogen-related antigens (FRA) present in clinical samples. No assay exists at present which is capable of distinguishing between fibrin and fibrinogen degradation products concurrently and in a clinical setting. The assay may be used as a tool with which to gain further insight to pathophysiology of disorders characterized by activation of the coagulation and fibrinolytic pathways. This study provides and analysis of the FRA profiles in patients with disorders characterised by possible enhanced fibrinolytic activity. Studies have been undertaken on patients with acute and chronic liver diseases, on patients with the various syndromes of coronary artery disease and on patients with insulin-dependent diabetes mellitus with and without evidence of microvascular disease. Certain observations made it evident that further studies were required in order to explain previously undocumented fibrinolytic abnormalities in certain patient groups. Data obtained from patients with liver disease provided information compatible with the activation of their fibrinolytic pathways. The initial scope of this study was then extended to further investigate the deranged haemostatic mechanisms in patients with severe liver diseases. Kinetic studies were performed which required the development of specific technology to be able to measure certain previously undertermined parameters. Mathematical models describing the rates of fibrin formation and lysis were developed for human studies. Fibrin-derived D-dimer was radiolabelled and its validity as and intravenous tracer and maker of fibrin degradation established

One case was operated for cosmetic reason and the other for obstructive symptoms which was noticed to be lymphoma after HPE.

  13. Clinical committee report: Recommendation for further clinical trials-patient studies

    International Nuclear Information System (INIS)

    The Cf-252 (Cf) neutron brachytherapy (NT) trials should continue to explore the feasibility of Cf-NT treatment of a variety of bulky human cancers. Results hitherto from the USA (Lexington), Japan, USSR, and England justify trials on a research basis. The term ''bulky'' is imprecise and in future studies should be specified by measurement. U.S. Department of Energy and other suppliers need to be advised to fabricate Cf-252 sources in more appropriate sizes, strengths and configurations for clinical therapy. Study of facility design and development should continue with special attention to: 1) treatment centers, 2) afterloading devices, 3) automated/robotics and other specialized equipment for handling Cf-252, 4) shields and shielding material, 5) controlled duration treatments, 6) necessary specialized equipment for conducting Cf-NT trials and 7) safety for personnel. In addition to the aforementioned, the report makes recommendations in several other areas such as doses and schedules, randomized trials, and records

    A number of clinical trials sponsored by the National Institutes of Health (NIH) use rigorous methods of data acquisition and analysis previously developed in fundamental biology and the physical sciences. The naive expectation that these trials would lead relatively rapidly to definitive answers concerning the therapeutic strategies and techniques under study is dispelled. This presentation focuses on delineating differences between the study of central tendencies and individual variation, more specifically on the strategy to study this variation: measure additional sources of variance within each patient at more timepoints and perhaps with greater precision. As rigorous orthodontic research is still in its infancy, the problem of defining the proper mix between prospective and retrospective trials is discussed. In view of the high costs of prospective clinical trials, many of the questions germane to orthodontics can be answered by well-conducted retrospective trials, assuming that properly randomized sampling procedures are employed. Definitive clinical trials are likely to require better theoretical constructs, better instrumentation, and better measures than now available. Reasons for concern are the restricted resources available and the fact that current mensurational approaches may not detect many of the individual differences. The task of constructing sharable databases and record bases stored in digital form and available either remotely from servers, or locally from CD-ROMs or optical disks, is crucial to the optimization of future investigations.

    Full Text Available OBJECTIVE: to assess the efficiency of the Calatonia technique about clinical parameters and pain in the immediate post-surgical phase. METHOD: a randomised study was carried out with 116 patients subjected to a cholecystectomy, by laparoscopy, divided into an experimental group (58 patients and a placebo group (58 patients. The experimental group received the Calatonia technique, while the placebo was only subjected to non-intentional touches. RESULTS: The placebo group and the experimental group were considered homogeneous in terms of the variables: sex, age, physical status classification, duration of surgical procedures and also the time spent recovering in the Post-Anaesthetic Recovery Room. The only variable to show a statistically significant difference was the axillary temperature of the body. In relation to pain, the experimental group showed significant results, and hence it is possible to deduce that the relaxation caused by the Calatonia technique brought some relief of the general situation of pain. CONCLUSION: The application of Calatonia can take up the function of a resource complementary to assistance in the period immediately after surgery.

    Ultrasound Computer Tomography (USCT) is a promising new imaging method for breast cancer diagnosis. We developed a 3D USCT system and tested it in a pilot study with encouraging results: 3D USCT was able to depict two carcinomas, which were present in contrast enhanced MRI volumes serving as ground truth. To overcome severe differences in the breast shape, an image registration was applied. We analyzed the correlation between average sound speed in the breast and the breast density estimated from segmented MRIs and found a positive correlation with R=0.70. Based on the results of the pilot study we now carry out a successive clinical study with 200 patients. For this we integrated our reconstruction methods and image post-processing into a comprehensive workflow. It includes a dedicated DICOM viewer for interactive assessment of fused USCT images. A new preview mode now allows intuitive and faster patient positioning. We updated the USCT system to decrease the data acquisition time by approximately factor two and to increase the penetration depth of the breast into the USCT aperture by 1 cm. Furthermore the compute-intensive reflectivity reconstruction was considerably accelerated, now allowing a sub-millimeter volume reconstruction in approximately 16 minutes. The updates made it possible to successfully image first patients in our ongoing clinical study.

    The clinical application of positron-emission-tomography-based reporter gene imaging will expand over the next several years. The translation of reporter gene imaging technology into clinical applications is the focus of this review, with emphasis on the development and use of human reporter genes. Human reporter genes will play an increasingly more important role in this development, and it is likely that one or more reporter systems (human gene and complimentary radiopharmaceutical) will take leading roles. Three classes of human reporter genes are discussed and compared: receptors, transporters and enzymes. Examples of highly expressed cell membrane receptors include specific membrane somatostatin receptors (hSSTrs). The transporter group includes the sodium iodide symporter (hNIS) and the norepinephrine transporter (hNET). The endogenous enzyme classification includes human mitochondrial thymidine kinase 2 (hTK2). In addition, we also discuss the nonhuman dopamine 2 receptor and two viral reporter genes, the wild-type herpes simplex virus 1 thymidine kinase (HSV1-tk) gene and the HSV1-tk mutant (HSV1-sr39tk). Initial applications of reporter gene imaging in patients will be developed within two different clinical disciplines: (a) gene therapy and (b) adoptive cell-based therapies. These studies will benefit from the availability of efficient human reporter systems that can provide critical monitoring information for adenoviral-based, retroviral-based and lenteviral-based gene therapies, oncolytic bacterial and viral therapies, and adoptive cell-based therapies. Translational applications of noninvasive in vivo reporter gene imaging are likely to include: (a) quantitative monitoring of gene therapy vectors for targeting and transduction efficacy in clinical protocols by imaging the location, extent and duration of transgene expression; (b) monitoring of cell trafficking, targeting, replication and activation in adoptive T-cell and stem/progenitor cell therapies

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

  20. Nasal polyps. A clinical radiological histopathological and mycological study

    International Nuclear Information System (INIS)

    Forty patients with nasal polyposis were studied. This study included clinical, haematological and mycological aspects. There were 24 females (60% of patients) and 16 males (40%). We found that all patients presented with nasal obstruction and nasal tone and the majority of them had allergic nasal symptoms such as sneezing and watery discharge. Thirty five percent of the patients were recurrent cases, being operated before for nasal polyps. Radiological investigations showed high of sinusitis and that 10% of the patients had complicated disease with orbital or intracranial extensions. Mycological studies revealed the presence of fungal infection in 4 patient (10%) and it was caused by Aspergillus flavus. Histological studies identified the allergic nature of the polyps in all patients. Surgical treatment was carried out in all patients and operations varied from simple intranasal polypectomy, intranasal ethmiodectomy, external ethmoidectomy to Caldwell-Luc operation for patients with antrochanal polyps.(Author)

    Background:Hypertriglyceridenia (HTG) is the most common etiology of acute pancreatitis (AP) after alcohol and gallstone-induced disease.Elevation of serum triglyceride (TG) levels to ≥ 1000 mg/dl in a patient with AP strongly indicates HTG as the cause.The absolute risk of pancreatitis based on serum TG ≤1000 mg/dl has not been clearly defined.The aims of this study were to address the role of elevated TG levels between 500 and 1000 mg/dl in the clinical course of HTG pancreatitis (HTGP);and assess the relationship between the level of serum TG and disease severity.Methods:A total of 224 HTGP patients between 2007 and 2011 were divided into two subgroups.Totally,122 patients in Group A had serum TG >1000 mg/dl;102 patients in Group B had maximal TG levels between 500 and 1000 mg/dl accompanied by lactescent serum;100 patients with biliary AP and 99 patients with alcoholic AP hospitalized during the study period were enrolled as controls.The clinical and biochemical data were analyzed.Results:The clinical presentation ofHTG-induced pancreatitis was similar to other causes.Severe form of AP in Group A was higher than Group B (x2 =4.002,P =0.045).The severity with HTGP was significantly higher as compared to biliaryAP (x2 =33.533,P =0.000) and alcoholic AP (x2 =7.179,P =0.007).Systemic complications with HTGP were significantly higher than biliary AP (x2 =58.763,P =0.000).Conclusions:The study demonstrated that TG level ≥500 mg/dl should raise a high degree of suspicion,especially if no other etiology of AP is apparent.The severity of HTGP seems to correlate directly with TG level.HTGP seems be more severe than other causes of AP.

  2. Redundant nerve roots of cauda equina in clinically neurologically asymptomatic patients. A clinical and radiographic study

    International Nuclear Information System (INIS)

    A radiographic study was conducted to determine the incidence of redundant nerve roots of the cauda equina (RNR) in neurologically asymptomatic patients, and to clarify whether RNR has an impact on the clinical symptom. 50 patients who had spine disease such as spondylosis and compression fracture were examined by MRI. They didn't have neurological symptom such as sciatica, leg numbness, and motor weakness of lower extremities. There were 18 men and 32 women, and their mean age was 72.4 years (range: 32-87 years). RNR was found in 18 of the 50 patients (36.0%) and in a higher percentage of the patients who had lumber spinal canal stenosis. We concluded that RNR was only a morphological change of the cauda equine and had little effect on the neurological symptom. (author)

  5. MRI Diagnosis of Intracranial Hemorrhage : Experimental and Clinical Studies

    International Nuclear Information System (INIS)

    The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, and add knowledge about the newer sequences increasing in use to depict intra parenchymal bleeds, especially T2*-w GE sequences. We also compared the effect of magnetic field strengths. The sequences and field strengths were tested in animals. Then, the most effective technique was applied to patients with hematomas of different ages and with hematoma residuals. Occurrence of residuals of earlier, clinically silent, haemorrhages in patients with acute spontaneous hematoma or with suspected ischemic stroke were compared. Experimental studies: The MR detectability of small experimental haematomas in the brain and of blood in the cerebrospinal fluid (CSF) spaces of 30 rabbits was evaluated. MRI examinations were performed at determined intervals using different pulse sequences at two field strengths. The last MR images were compared to the formalin fixed brain sections and, in 16 rabbits, also to the histological findings. T2*-weighted GE sequences revealed all the intra parenchymal haematomas at 1.5 T: they were strongly hypointense. Their sizes became smaller but the signal patterns remained unchanged during the follow-up. The haematoma sizes and shapes corresponded well to gross pathology at acute and subacute stages. At chronic stage, the signal changes were larger than iron deposits. Blood in the CSF spaces was best detected at 1.5T with T2*-weighted GE sequences during the first 2 days. The FLAIR sequence often revealed blood in CSF spaces but not in the brain. SE sequences were rather insensitive. Imaging at 0.5 T was less effective than at 1.5 T. Clinical studies: All MR examinations on patients were performed at 1.5T, including T1- and T2-w SE, FLAIR, T2*-w GE sequences, and, occasionally, diffusion-w sequences. Sixty-six intra parenchymal hematomas were examined in the first clinical study. The hematomas were of different sizes and the ages varied from 8 hours to 3

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

    After a review of the clinical studies on the treatment of diabetic patients with pantethine, the authors discuss the results obtained in a postmarketing surveillance (PMS) study on 1045 hyperlipidemic patients receiving pantethine (900 mg/day on average). Of these patients, 57 were insulin-dependent (Type I) and 241 were non insulin-dependent (Type II) diabetics. Beyond the epidemiological considerations made possible by a PMS study, the authors show that pantethine brought about a statistically significant and comparable improvement of lipid metabolism in the three groups of patients, with very good tolerability. Pantethine should therefore be considered for the treatment of lipid abnormalities also in patients at risk such as those with diabetes mellitus. PMID:2524328

    The purpose of this clinical study was to introduce technique for correct positioning of the needle into the center of the disc for discography by means of CT analysis and also to clarify usefulness of CT discography for diagnosis of the lumbar disc herniation. We have taken CT analysis in order to determine correct place and the angle of inserting the needle. This measurement provides easy needle insertion. Unless the needle tip places center of disc, discogram false positive or negative will occur as a result. The materials of this study are 222 discs of 105 cases with the lumbar disc herniation. Comparative study of the findings among myelography, discography and CT discography was investigated. The results indicated that CT discography demonstrates the most clear findings and is useful in the diagnosis of lumbar disc herniation, especially in obtaining detailed observation of herniated discs.

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

Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. This study aims to evaluate C linical features, Investigations, various Treatment modalities and the Clinico - pathological correlation & outcome of various treatment modalities of LABC, with special emphasis on Neo - adjuvant chemotherapy (NACT in Indian setting. MATERIAL AND METHOD : This was a non - randomised prospective observational study. We analyzed 57 patients of LABC Stage IIIB & IIIC presenting at Government Medical College, Nagpur, Maharashtra, a tertiary care C entre from September 2012 to November 2014. RESULTS : Stage IIIB comprised 84.21% patients while remaining 15.79% were having Stage IIIC disease. Skin involvement was observed in 91.23% patients. 15.79% showed supraclavicular lymph node involvement. 32 patients received NACT (2 to 6 cycles. Out of these 32, complete clinical response (cCR was 12.5%, partial response (cPR was 68.75% and pathological CR (pCR was 6.25% with Total Objective response (cCR+cPR 81.25%. Feasibility of Breast Conserving Surgery (BCS was observed in 12.5% patients. 25 patients underwent primary surgery followed by adjuvant chemotherapy. Modified Radical Mastectomy was performed in 89.48% patients. CONCLUSIONS : With overall clinical response of 81.25%, n eoadjuvant chemotherapy is the best treatment option for patients with Locally Advanced Breast Cancer with added advantage of in vivo testing the sensitivity of chemotherapeutic agents, early management of micrometastasis and down staging the primary tumour with feasibility of BCS. Patients presenting LABC constitute a diverse group for whic h a variety of treatment modalities should be instituted with co o rdinated treatment planning among surgeons

    Full Text Available Objective: To evaluate five biomarkers (neopterin, vascular endothelial growth factor-A, thrombomodulin, soluble vascular cell adhesion molecule 1 and pentraxin 3 in differentiating clinical dengue cases. Methods: A prospective cohort study was conducted whereby the blood samples were obtained at day of presentation and the final diagnosis were obtained at the end of patients’ follow-up. All patients included in the study were 15 years old or older, not pregnant, not infected by dengue previously and did not have cancer, autoimmune or haematological disorder. Median test was performed to compare the biomarker levels. A subgroup Mann-Whitney U test was analysed between severe dengue and non-severe dengue cases. Monte Carlo method was used to estimate the 2-tailed probability (P value for independent variables with unequal number of patients. Results: All biomarkers except thrombomodulin has P value < 0.001 in differentiating among the healthy subjects, non-dengue fever, dengue without warning signs and dengue with warning signs/severe dengue. Subgroup analysis for all the biomarkers between severe dengue and non-severe dengue cases was not statistically significant except vascular endothelial growth factor-A (P < 0.05. Conclusions: Certain biomarkers were able to differentiate the clinical dengue cases. This could be potentially useful in classifying and determining the severity of dengue infected patients in the hospital.

  15. Retroperitoneal and pelvic hemangiopericytomas: A clinical, radiologic, pathologic correlative study

    International Nuclear Information System (INIS)

    The hemangiopericytoma (HP) is an aggressive neoplasm consisting of proliferation of endothelial-lined capillaries with intact reticulum sheaths surrounded by the pericyte. Approximately a fifth of these lesions occur in the retroperitoneum. This is the first large clinical, radiologic, pathologic study of retroperitoneal HP (17 cases). Significant clinical findings included a palpable mass (64%) and hypoglycemia in one. Approximately 40% were located in the true anatomic pelvis or near the cecum along the pelvic psoas muscle. Radiographically, a mass may be seen on plain film, IVP, or barium studies which might displace, compress, or rarely invade an adjacent organ. Most significant was the angiographic findings of an extremely vascular tumor with extensive collateralization, hypertrophy of vessels, and venous engorgement. On CT, HP appeared as a large, bulky well-defined enhancing tumor occasionally with areas of low density in a swirled or marbled pattern. Although by no means diagnostic, HP can be considered when a hypervascular retroperitoneal tumor is encountered on angiography or a large, enhancing mass with several low-density areas is recognized on CT

    Full Text Available Background: Even though herpes zoster is a common condition its incidence and pattern of occurrence in the era of HIV disease is significant. Aim: To analyze the incidence, pattern of occurrence and evolution of herpes zoster with special attention to provocative factors if any. Materials and Method s: This was an analytical study conducted for 2 years based on a preformed proforma containing preliminary information, a detailed clinical evaluation regarding the segment of involvement, morphology, pattern of lesions, complications, disseminations etc. and investigations to establish provocative factors if any. Results: Incidence of herpes zoster was mainly in the fourth and third decades of life. A definite history of chicken pox was present in only 63.4% cases. In the majority (70% herpes zoster occurred spontaneously. In 30% cases, immunosuppression due to chemotherapy, malignancy, HIV infection, diabetes mellitus were observed. The commonest segment affected was thoracic (42.4% followed by cranial (28.2% and cervical (12.1%. Majority resolved in 7-14 days except immunosuppressed. 34.6% of the patients had complications such as secondary bacterial infection, post herpetic neuralgia, and motor weakness. Ten patients had HIV infection as a provocative factor. Conclusion: The results of incidence and clinical pattern of herpes zoster is almost parallel to the previous studies. Any factors of immunosuppression should be checked, especially HIV, particularly in disseminated and long-lasting cases.

  18. Clinical study on 44 cases of femoral hernia

    International Nuclear Information System (INIS)

    Femoral hernia is a surgical disease that is frequently associated with incarceration and necessitates emergency surgery. However, there are only a few studies referred which have compared emergency and elective surgery for femoral hernias. We retrospectively reviewed the clinical characteristics of patients diagnosed as having femoral hernia between 2005 and 2009 in our institution. The clinical features of emergency repairs were compared with those of elective ones, and diagnostic values of preoperative diagnostic modalities were studied. The mean age of the patients was 73±12 years. Females comprised 68% of the cases, and right femoral hernias comprised 70% of the cases. Incarceration was associated with 66% of the cases (29 patients), and emergency surgery was performed in 52% of the patients (23 patients). Bowel resection was performed in 32% of the cases (14 patients). The mean age, body temperature, white blood cell (WBC) count, and LDH value were higher in the emergency repairs than in the elective one, and most of the hernias were repaired with McVay's procedure. CT scans had a high diagnostic value in detecting femoral hernias (44%) and incarceration (88%). It was confirmed that femoral hernias were frequently associated with incarceration and CT scan has a high diagnostic value in femoral hernias. (author)

    Different clinical tests have been suggested in the literature as significant indicators of anterior shoulder instability. Sometimes patients with recurrent anterior shoulder instability may show some muscular guarding thus making the evaluation of specific clinical tests very difficult. These patients may also report a medical history with posterior shoulder pain that can be also elicited during some clinical manoeuvres. From September 2005 to September 2006 we prospectively studied patients who underwent an arthroscopic anterior capsuloplasty. Shoulder clinical examination was performed including anterior shoulder instability tests (drawer, apprehension and relocation tests). Furthermore the exam was focused on the presence of scapular dyskinesia and posterior shoulder pain. The patients were also evaluated with ASES, Rowe, SST (Simple Shoulder Test), Constant and UCLA (University of California at Los Angeles) scoring system preoperatively and at the latest follow-up time. In the period of this study we observed 16 patients treated for anterior gleno-humeral arthroscopic stabilisation, who preoperatively complained also of a posterior scapular pain. The pain was referred at the level of lower trapezium and upper rhomboids tendon insertion on the medial border of the scapula. It was also reproducible upon local palpation by the examiner. Four of these patients also referred pain in the region of the insertion of the infraspinatus and teres minor. After arthroscopic stabilisation the shoulder was immobilised in a sling with the arm in the neutral rotation for a period of 4 weeks. A single physician supervised shoulder rehabilitation. After a mean time of 6.8 months of follow-up, all the shoulder scores were significantly improved and, moreover, at the same time the patients referred the disappearance of the posterior pain. Posterior scapular shoulder pain seems to be another complaint and sign that can be found in patients affected by anterior shoulder instability

    Full Text Available Background: Conventional, non-surgical periodontal therapy consists of supra- and subgingival tooth debridement. However, it is a technically demanding procedure and is not always efficient at eradicating all periodontal pathogens and in reducing inflammation. Therefore, local subgingival application of other chemotherapeutic agents may be used as an adjunct to non-surgical therapy. The aim of this study was to investigate the clinical and histological outcomes of local subgingival application of 0.2% hyaluronic acid gel (GENGIGEL® as an adjunct to scaling and root planing (SRP in chronic periodontitis patients. Materials and Methods: One hundred and twenty sites were chosen from 26 patients with chronic periodontitis (criteria being periodontal pockets ≥5mm. Experimental sites additionally received HA gel subgingivally at baseline, 1 st , 2 nd , and 3 rd week. Clinical parameters were re-assessed at 4 th , 6 th , and 12 th week. At 4 th week recall, a gingival biopsy was obtained from test and control site for histologic examination. Results: Intra-group analysis of all the clinical parameters at all sites from baseline to 4 th , 6 th , and 12 th week showed statistically significant changes. Experimental sites showed statistically significant improvement in Gingival index and Bleeding index at 6 th and 12 th week when compared with control sites. However, no statistically significant differences were observed in the PPD and RAL between control and experimental sites at 4 th , 6 th , and 12 th week time interval. No statistically significant association was found between the histological grading of the sites that received HA treatment. Conclusion: Subgingival placement of 0.2% HA gel along with SRP provided a significant improvement in gingival parameters. However, no additional benefit was found in periodontal parameters. Histologically, experimental sites showed reduced inflammatory infiltrate, but it was not statistically significant.

  5. Nd:YAG laser in caries prevention: a clinical study

    International Nuclear Information System (INIS)

    The caries prevention by using laser irradiation has been investigated during the last 30 years. The Nd: YAG laser associated with acidulated phosphate fluoride has been shown as a very promising technique for enamel caries prevention. The aim of this work was to clinically evaluate the efficiency of Nd: YAG laser associated with acidulated phosphate fluoride in pit and fissure caries prevention of children and adolescents. In this work it was determined the dye that enhance the effect of Nd: YAG laser in enamel. It was selected 242 pre-molar and molar teeth from 33 children and adolescents, aged from 7 to 15 years old. The selected teeth were free from caries or decalcification marks (active white marks) to the clinical and radiographic exams. The teeth were divided into two groups: the first group was laser irradiated and their homologous remained as a control. The right side teeth were dye-assisted Nd:YAG laser irradiated. The dye solution was a moisture of dust coal and equal parts of water and alcohol. The irradiation conditions were 60 mJ/10 Hz, optical fiber in contact mode, with diameter of 300 μm, resulting in an energy density of 84,9 J/cm2. The oclusal surface of the teeth was completely irradiated, specially on the slopes and in the deepest part of the pits and fissures. This procedure was repeated three times. In the sequence it was applied the acidulated phosphate fluoride for 4 minutes. On the left side teeth - control group- only acidulated phosphate fluoride was applied for the same time. The final examination considered the presence of caries and active white marks after a period of one year. There were statistical significant differences (p < 0.01) between the lased + fluoride group and the non irradiated group. The present study concluded that the technique used in this work can be an alternative clinical method for caries prevention. (author)

    Urticarial vasculitis (UV) is a subset of cutaneous vasculitis (CV), characterized clinically by urticarial skin lesions of more than 24 hours' duration and histologically by leukocytoclastic vasculitis. We assessed the frequency, clinical features, treatment, and outcome of a series of patients with UV. We conducted a retrospective study of patients with UV included in a large series of unselected patients with CV from a university hospital. Of 766 patients with CV, UV was diagnosed in 21 (2.7%; 9 male and 12 female patients; median age, 35 yr; range, 1-78 yr; interquartile range, 5-54 yr). Eight of the 21 cases were aged younger than 20 years old. Potential precipitating factors were upper respiratory tract infections and drugs (penicillin) (n = 4; in all cases in patients aged urticarial lesions, other features such as palpable purpura (n = 7), arthralgia and/or arthritis (n = 13), abdominal pain (n = 2), nephropathy (n = 2), and peripheral neuropathy (n = 1) were observed. Hypocomplementemia (low C4) with low C1q was disclosed in 2 patients. Other abnormal laboratory findings were leukocytosis (n = 7), increased erythrocyte sedimentation rate (n = 6), anemia (n = 4), and antinuclear antibody positivity (n = 2). Treatment included corticosteroids (n = 12), antihistaminic drugs (n = 6), chloroquine (n = 4), nonsteroidal antiinflammatory drugs (n = 3), colchicine (n = 2), and azathioprine (n = 1). After a median follow-up of 10 months (interquartile range, 2-38 mo) recurrences were observed in 4 patients. Apart from 1 patient who died because of an underlying malignancy, the outcome was good with full recovery in the remaining patients. In conclusion, our results indicate that UV is rare but not exceptional. In children UV is often preceded by an upper respiratory tract infection. Urticarial lesions and joint manifestations are the most frequent clinical manifestation. Low complement serum levels are observed in a minority of cases. The prognosis is generally good

    2001-01-01

    Full Text Available INTRODUCTION: Friedreich's ataxia is a neurodegenerative disorder whose clinical diagnostic criteria for typical cases basically include: a early age of onset (< 20 or 25 years, b autosomal recessive inheritance, c progressive ataxia of limbs and gait, and d absence of lower limb tendon reflexes. METHODS: We studied the frequency and the size of expanded GAA and their influence on neurologic findings, age at onset, and disease progression in 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia - 19 typical and 6 atypical - using a long-range PCR test. RESULTS: Abnormalities in cerebellar signs, in electrocardiography, and pes cavus occurred more frequently in typical cases; however, plantar response and speech were more frequently normal in this group when the both typical and atypical cases were compared. Homozygous GAA expansion repeats were detected in 17 cases (68% - all typical cases. In 8 patients (32% (6 atypical and 2 typical, no expansion was observed, ruling out the diagnosis of Friedreich's ataxia. In cases with GAA expansions, foot deformity, cardiac abnormalities, and some neurologic findings occurred more frequently; however, abnormalities in cranial nerves and in tomographic findings were detected less frequently than in patients without GAA expansions. DISCUSSION: Molecular analysis was imperative for the diagnosis of Friedreich's ataxia, not only for typical cases but also for atypical ones. There was no genotype-phenotype correlation. Diagnosis based only on clinical findings is limited; however, it aids in better screening for suspected cases that should be tested. Evaluation for vitamin E deficiency is recommended, especially in cases without GAA expansion.

    Prior research strongly implicates gastric acid and bile acids, two major components of the gastroesophageal refluxate, in the development of Barrett's esophagus and its pathogenesis. Ursodeoxycholic acid (UDCA), a hydrophilic bile acid, has been shown to protect esophageal cells against oxidative stress induced by cytotoxic bile acids. We conducted a pilot clinical study to evaluate the clinical activity of UDCA in patients with Barrett's esophagus. Twenty-nine patients with Barrett's esophagus received UDCA treatment at a daily dose of 13 to 15 mg/kg/day for 6 months. The clinical activity of UDCA was assessed by evaluating changes in gastric bile acid composition and markers of oxidative DNA damage (8-hydroxydeoxyguanosine), cell proliferation (Ki67), and apoptosis (cleaved caspase-3) in Barrett's esophagus epithelium. The bile acid concentrations in gastric fluid were measured by liquid chromatography/mass spectrometry. At baseline, UDCA (sum of unchanged and glycine/taurine conjugates) accounted for 18.2% of total gastric bile acids. After UDCA intervention, UDCA increased significantly to account for 93.4% of total gastric bile acids (P < 0.0001). The expression of markers of oxidative DNA damage, cell proliferation, and apoptosis was assessed in the Barrett's esophagus biopsies by IHC. The selected tissue biomarkers were unchanged after 6 months of UDCA intervention. We conclude that high-dose UDCA supplementation for 6 months resulted in favorable changes in gastric bile acid composition but did not modulate selected markers of oxidative DNA damage, cell proliferation, and apoptosis in the Barrett's esophagus epithelium.

    Full Text Available Abstract The aim of the present study was to describe the clinical and echocardiographic findings of ventricular noncompaction in adult patients. Fifty-three patients underwent complete clinical history, electrocardiogram, Holter and transthoracic echocardiogram. Forty patients (75% were in class I/II of the New York Heart Association, and 13 (25% in class III/IV. Ventricular and supraventricular escape beats were found in 40% and 26.4%, respectively. Holter showed premature ventricular contractions in 32% and sustained ventricular tachycardia in 7.5%. Ventricular noncompaction was an isolated finding in 74% of cases and was associated with other congenital heart disease in 26%. Noncompacted ventricular myocardium involved only left ventricle in 62% of the patients and both ventricles in 38%. The mean ratio of noncompacted to compacted myocardial layers at the site of maximal wall thickness was 3.4 ± 0.87 mm (range 2.2–7.5. The presence of ventricular noncompaction in more than three segments was associated with a functional class greater than II and ventricular arrhythmia with demonstrable statistical significance by χ2(p Conclusion a Noncompacted cardiomyopathy is a congenital pathological entity that can occur in isolated form or associated with other heart disease and often involves both ventricles. b A ratio of noncompacted to compacted myocardium greater than 3 and involvement of three or more segments are indicators of poor prognosis. c Since the clinical manifestations are not sufficient to establish diagnosis, echocardiography is the diagnostic tool that makes it possible to document ventricular noncompaction and establish prognostic factors.

    Full Text Available Background: Dengue an endemic disease in most subtropical and tropical regions of the world is causing severe epidemics in India. An alarming rise of dengue has also been seen in Mumbai, during the recent years. Aim and Objective: The study was conducted to know the prevalence of dengue infection, based on laboratory rapid screening tests for IgM and IgG antibodies and the confirmatory IgM ELISA test and to study the seasonal variation and the clinical profile in these cases. Material and Method: A retrospective study of laboratory test results and clinical profile of suspected dengue cases was carried out in a tertiary care hospital over a period between January 2004 and November 2007. Result: Of the 3 677 samples processed by rapid test for antibodies against dengue (Denguchek, 503 (13.67% gave positive results. Fifty-six samples (26.41% were positive by IgM Enzyme linked immunosorbent assay (ELISA test, of 212 rapid positive samples processed by ELISA test. Our study comprised of 315 adult and 188 pediatric cases. The common symptom of dengue was fever, icterus, myalgia, and headache. Thrombocytopenia (platelet counts <75 000/cmm was seen in 386 (76.74% cases. Seventy-seven cases (15.30% positive by rapid screening tests for dengue antibodies were also positive for IgM/IgG antibodies against Leptospira by Dridot test (Rapid test. Of these, 49 (63.64% were confirmed to be positive for dengue antibodies by the ELISA test. Conclusion: As dengue causes increased morbidity and mortality and requires prompt diagnosis and treatment for the proper management of these cases, the rapid screening test for IgM/IgG antibodies helps clinicians toward achieving this goal.

    In 1980s, abuse and dependence of BRON-W syrup (cough suppressant), which contains methylephedrine, dihydrocodeine, chlorpheniramine and caffeine, were prevalent in Japan. Pharmacological and clinical studies suggest that methylephedrine and dihydrocodeine cause dependence. Although BRON-L syrup, newly modified cough suppressant contains only chlorpheniramine and caffeine, there still are abuse and dependence of this drug. In this report, three cases of BRON-L syrup abuse are demonstrated. All cases started using BRON-L syrup in the late teens in their peer groups, and dropped out from school. Case 1 misused only BRON-L syrup, but case 2 and 3 were multi-drug abusers (case 2: amphetamine, cocaine, and marijuana, case 3: solvent, alcohol, bromovalerylurea), and had kept in tough with the peer groups. Case 2 and 3 hospitalized more than 2 times. Withdrawal symptoms, such as headache, insomnia, and irritability were mild and improved in a few weeks after drug use was stopped. These findings suggest that 1) psychosocial backgrounds of these cases are in common with those of BRON-W syrup abusers, but 2) the clinical course and prognosis of multi-drug abusers are different from the BRON single abuser, 3) chlorpheniramine and caffeine possibly cause dependence, 4) abusers are likely to choose BRON brand although two main dependence-producing constituents are removed from it now. Therefore, prevention and care of BRON-L abusers requires both psychosocial and pharmacological aspects. PMID:11915306

    Full Text Available Onychomycosis or fungal infection of the nails is a common disease, especially in older persons. A mycological study of onchomycosis was undertaken in 75 patients. The nails were judged to be infected by their clinical appearance. There were a total of 75 suspected cases of onychomycosis. Of these 75 cases 22.6% were positive by direct microscopy and 33.3% were culture positive. Of these 75 cases, 18 were males (24% and 57 (76 % were females, male to female ratio being. The commonest age group was 31-40 years followed by 21-30 years. The finger nails were more frequently involved. i.e. 45 (60 %, followed by toe nails 30 (40 % and both in 18 (24% cases. Ratio of finger nail to toe nail infection was 1.5:1. Distal and lateral subungual onychomycosis (DLSO was the commonest clinical pattern (76% followed by total dystrophic onychomycosis (18.66% and then superficial white onychomycosis (4% and proximal subungual onychomycosis (1.33%. The most common fungal isolates were dermatophytes of which 44% were Trytophyton rubrum, 4% were Trytophyton mentagrophytes. Non dermatophyte moulds constituted 16% of the fungus isolates. Onychomycosis was found to be the commonest in housewives (52%, followed by serviceman / businessman (32% followed by farmers (8% and labourer and student 4% each.

  14. Antioxidant vitamins in atherosclerosis--animal experiments and clinical studies.

    Atherosclerotic heart diseases are universal problems in modern society. Oxidative damage to lipids is a primary cause of atherosclerosis. There are many choices for treatment, but no definite recommendations to prevent the occurrence of the disease. There is a relationship between atherosclerotic risk factors and increased vascular production of reactive oxygen species (ROS). Oxidized low-density lipoproteins (LDL) and ROS may directly cause endothelial dysfunction by reducing endothelial nitric oxide (NO) bioavailability. Vitamin E can to some degree prevent the consequences of oxidized LDL, and vitamin C provides NO synthase activity. Although prolonged use of vitamin A, C, and E supplementation in pharmaceutical forms has been proven to be effective in preventing atherosclerosis in animal experiments, this has not yet been demonstrated in clinical trials with human beings. It should be taken into account that the evidence has been gathered from young/adult experimental animals with early stages of arthrosclerosis and from in-vitro studies, while most of the clinical trials have involved older patients with late stages of the disease. Prolonged use of vitamins in the diet has not yet been recommended in human beings. There is some indication that a diet rich in antioxidant fruit and vegetables may be beneficial in the prevention of cardiovascular events. PMID:23214308

    Full Text Available Waste generation depends on numerous factors such as established waste management methods, type of hospital establishment, hospital specialization, proportion of reusable items employed in hospital, and proportion of patients treated on a day-care basis. This study surveyed the waste from hospital and clinics in Phitsanulok and found the average daily waste generated as general, medical and hazardous waste from all hospitals in Phitsanulok Province at 1.751, 0.284 and 0.013 kg/bed respectively and at 0.323, 0.041 and 0.002 kg/bed respectively from all clinics in Phitsanulok Province. Medical waste from all hospitals consisted of needles, gloves, drain tubes, cottons and gauze, napkins, plastic syringes, swap and body parts with total daily generation at 0.452, 0.480, 0.390, 0.404, 0.018, 0.355, 0.004 and 0.382 kg/bed respectively. Information about proper waste management process is needed to improve hospital waste management. Hospital waste management is an important and necessary component of environmental health protection.

    Full Text Available In combination with whole report and partial report tasks, the Theory of Visual Attention (TVA can be used to estimate individual differences in five basic attentional parameters: The visual processing speed, the storage capacity of visual short-term memory, the perceptual threshold, the efficiency of top-down selectivity, and the spatial bias of attentional weighting. TVA-based assessment has been used in about 30 studies to investigate attentional deficits in a range of neurological and psychiatric conditions: (a neglect and simultanagnosia, (b reading disturbances, (c aging and neurodegenerative diseases, and most recently (d neurodevelopmental disorders. The article introduces TVA based assessment, discusses its methodology and psychometric properties, and reviews the progress made in each of the four research fields. The empirical results demonstrate the general usefulness of TVA-based assessment for many types of clinical neuropsychological research. The method’s most important qualities are cognitive specificity and theoretical grounding, but it is also characterized by good reliability and sensitivity to minor deficits. The review concludes by pointing to promising new areas for clinical TVA-based research.

  17. Clinical study of cerebral infarction in hemodialysis patients

    International Nuclear Information System (INIS)

    Stroke is one of the leading causes of death in patients undergoing chronic dialysis. However, few clinical studies have so far examined stroke, especially brain infarction, under such conditions. We retrospectively evaluated the clinical features and risk factors for brain infarction in 33 patients undergoing hemodialysis (hemodialysis, 29 patients; continuous ambulatory peritoneal dialysis, 4 patients; male:female ratio, 25:8) between May 2003 and August 2006. The mean age was 68.5±10.9 (mean±standard deviation (SD)) years. The basal renal diseases were chronic glomerulonephritis (n=16), diabetes mellitus (n=10) and other diseases (n=7). The mean duration of maintenance dialysis before the onset of stroke was 5.6±5.2 years. All 33 patients developed brain infarction, including the atherothrombotic (n=13), lacunar (n=9) and cardioembolic (n=11) types. The complications included a high frequency of hypertension (79%) in all groups, diabetes mellitus (36%) and atrial fibrillation (21%). Four of the patients, 2 with lacunar and 2 with atherothrombotic infarction, developed brain infarction within 3 hours after hemodialysis. Hemodynamic changes might have caused the infarction in these patients. The proportion of patients with a modified Rankin Scale grade of 4-6 at discharge was 42%, and the mortality rate was high (15%). The prognosis of brain infarction was poorer in patients with hemodialysis than in those without. (author)

    Objective To investigate the clinical and electrophysiological features of chronic inflammatory demyelinating polyneuropathy (CIDP) . Methods The clinical symptoms and signs of 11 patients with CIDP were studied, motor conduction velocity( MCV), sensory con-duction velocity (SCV) and Electromyography (EMG) were also respectively carried out on 54 motor nerves, 28 sensory nerves and 21 musclesof these 11 cases. The amplitudes of compound muscle action potential(CAMP) obtained from distal and proximal ends were compared to as-certain the presence of conduction block (CB) by stimulating the segments starting from the distal ends. Results More than 3 nerves werefound involved in 10 out of 11 cases, slow MCV were found in 52%, prolongation of the distal latency in 64%, reduction of the amplitudes ofCAMP in 68%, CB in 26%, slow SCV in 85. 7%. EMG revealed neurogenic damage in 81%. Conclusion CIDP is a peripheral de- myelinating neuropathy involving not only the prox imal and distal segments but also the sensory and motor nerves. If there were no conditionsto perform nerve biopsy, testing of protein in CSF and electrophysiology mightbe of important diagnostic value for CIDP.

    Full Text Available `INTRODUCTION: Stroke is the third leading cause of death in developed countries after cardiovascular disease and cancer. In India Community Surveys have shown a crude prevalence rate for hemiplegia 200 per 1, 00, 000 population. It accounts for nearly 1.5% of all urban admissions, 4.5 % of all medical and about 20% of neurological cases. AIMS AND OBJECTIVE: Identification of risk factors and evaluation of clinical profile of acute stroke. MATERIAL AND METHOD: INCLUSION CRITERIA: Cases of acute stoke admitted in SGMH hospital were selected for the study. EXCLUSION CRITERIA: Brain injury cases, infective, neoplastic cases producing stroke were excluded. RESULTS: Stroke was more common in male, 58 % patients were male and 42% patients were female. It was more common in 5th and 6th decade. Most common etiology was infarction. Most common risk factor was hypertension followed by smoking. In addition to limb weakness, headache and vomiting were most common presenting symptoms followed by convulsion. These symptoms were more common in hemorrhagic stroke. Right sided hemiplegia was more common than left sided. Middle cerebral artery was involved in majority of cases in atherothrombotic stroke whereas basal ganglion was most common site of bleed in hemorrhagic stroke. Coma and mortality were more in hemorrhagic stroke. CONCLUSION: The risk factors and clinical profile of acute stroke in India are similar to that of Western countries. Common risk factors are hypertension, smoking, diabetes mellitus and hyperlipidemia

    Full Text Available Purpose. Bedside teaching (BST of medical students has become less common in recent years; however, there have been strong recommendations made in the literature to continue this teaching modality for the valued benefits it provides. The purpose of the present study is to explore the perceptions and opinions of bedside teaching among senior Australian medical students. Methods. Medical students at Australian universities were surveyed by means of an electronic questionnaire. The results were collected and analysed. Results. A total of 517 responses were received from students at 15 universities and 94 different clinical sites. The percentage of students who identified BST as very important ranged from 62.5% in psychiatry to 90.4% in internal medicine. The optimal class size was nominated as 3-4 students, and students favoured a style where one individual performs a complete examination, with the remainder allowed to elicit the key sign afterwards. Students felt 3-4 hours of BST per week to be ideal. Advantages identified to BST included provision of feedback and elicitation of clinical signs. Disadvantages included time constraints and excessive class sizes. Conclusions. The unique benefits of BST result in its high demand by students, regardless of the discipline being taught.

  1. Clinical, chromosomal and endocrine studies for congenital adrenal hyperplasia

    International Nuclear Information System (INIS)

    Severe forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study was to clarify the clinical presentation together with the chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from Children's Hospital, Cairo University, Egypt, for hormonal and chromosomal workup. The age ranged from eight months to 19 years with mean age of 3.18 years. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Severe salt wasting form was present in ten patients whereas simple virilisation was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The sex of rearing was female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was 46,XX in all cases, the diagnosed correct sex was delayed in six cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P), dehydroepiandrosterone sulfate (DHEAS), delta, 4-androstenedione (D4A), testosterone (T) and 11-deoxycortisol were all elevated as compared to controls. It was found that the adrenal androgens DHEAS, D4A and T were more elevated in salt losers when compared to simple virilising patients. However, this difference was statistically non-significant. The present study demonstrates that the clinical examination and laboratory investigations are necessary for the early detection and treatment of these cases to avoid major medical and psychological problems for the patients and their parents

    Several forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study is to throw light on the clinical presentation together with chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from the Diabetic Endocrine Metabolic Pediatric Unit [DEMPU], Children's Hospital, Cairo University for hormonal and chromosomal workup. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Sever salt wasting form was present in ten patients whereas simple virilization was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The mean age was 3.18 years, ranging from eight months to 19 years. The sex of rearing was Female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was (46,XX) in all cases, the correct sex diagnosis was delayed in 6 cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P); Dehydroepiandrosterone sulfate (DHEAS); Delta,4-androstenedione (D 4 A); Testosterone and 11-deoxycortisol were all elevated in relation to controls. We found that the adrenal androgens DHEAS, delta 4A, and T were more elevated in salt losers when compared to simple virilizing patients. However, this difference was not of statistical significance. The present study demonstrates that clinical examination and laboratory investigations are necessary for early detection and treatment of hese cases to avoid major medical and psychological problems for the patients and their parents.

    Full Text Available BACKGROUND AND OBJECTIVES To study the clinical aspects of benign lesions of pinna and to evaluate aetiopathological factors, prevalence and management options. METHODS The study included 115 patients during the period from January 2013 to December 2013. The selection criteria included patients presenting with swellings of pinna which included keloids, seromas, sebaceous cyst, preauricular sinus, haemangioma, dermoid and neurofibroma. A detailed clinical history regarding onset, predisposing factors and associated conditions was documented and analysed. RESULTS Of total 115 cases in our study, 66 cases (57% presented with keloid followed by 33 cases (29% of pseudocyst of auricle, sebaceous cyst were seen in 10 cases, i.e. 9% and only 1 case of Neurofibroma, Haemangioma and Dermoid was diagnosed (<1%; 94 percent of patients presenting with Keloid were females; 88% of them had unilateral and just 12% had bilateral disease. Trauma was the factor in causation of pseudocyst of auricle in 11 cases (34%, diabetes also was seen in 3 cases (9%. Of all 33 cases of pseudocyst of auricle, 27 cases (82% were managed by window procedure and 6 cases (18% were managed with aspiration. CONCLUSION Trauma is the most important factor in causation of number of benign lesions of pinna. Other factors being high ear piercing through the cartilage. Diabetes mellitus plays a significant role and should be controlled simultaneously. Wide bore needle aspiration can be done for some of the cases of seroma patients who have recurrence and other cases can be managed by window procedure. Other lesions like keloid, sebaceous cyst, haemangioma and dermoid can be managed by complete surgical excision. A firm pressure bandage should be applied in most of the cases after surgery. Neurofibroma can be managed conservatively.

    Full Text Available Hypertension in children, although an uncommon entity, is associated with end-organ damage. We tried to study the clinical profile of hypertension in children presented to our hospital. The medical records from January 1990 to December 2010 of all children aged 18 years and younger with hypertension were studied. The patients were divided into four age groups (infants, pre-school age, school age and adolescents Presenting symptoms and other clinical parameters were thoroughly evaluated. The results were compared with previous studies on hypertension in children. A total of 135 patients were selected (male:female 103:32, with mean age of 0.4 ± 2.1 years (range: six months to 17 years. The most common age group affected was the adolescents group (42.9%. The most common clinical feature at presentation was dizziness (30.3%, followed by headache and chest discomfort (22.9%. Transient hypertension was detected in 34 patients (25.2%, and was most common in the adolescent age group, whereas sustained hypertension was noticed in 101 patients (74.8% and was the most common in the school age group (36/45, 80%. Forty-two patients (31.1% presented with hypertensive crisis. Nine patients were considered to have essential hypertension. The chief causes included chronic glomerulonephritis in 56 (41.5%, endocrine disorders in 21 (15.5%, obstructive uropathy in 16 (11.8%, reflux nephropathy in 12 (8.8% and renovascular disease in 5 (3.7%. Takayasu′s disease was the most common cause of renovascular hypertension. Coarctation of aorta was the most common cause of hypertension in infancy, being present in 40% of the cases. Hypertension in children may be easily underestimated but is a potentially life-threatening problem. Most of them are asymptomatic and a large chunk has an underlying etiology. Primary care clinicians should promptly identify patients with hypertension and treat them immediately and appropriately to prevent damage to the cardiovascular organs.

    Full Text Available Retinal vein occlusion is the most common retinal occlusive disorder encountered by Ophthalmologists and is usually associated with a variable amount of visual loss. This is the second most common retinal vascular disease next to diabetic retinopathy. Liebreich initially described dramatic obstruction of veins as retinal apoplexy. Leber ( 1 (1877 reported the first case of BRVO and called it Hem orrhagic retinitis. RVO most commonly affects the venous blood supply of the entire retina (CRVO or a quadrant drained by one of the branches (BRVO or less commonly the superior or inferior half of the retina alone is affected (HCRVO. For discussion and management purpose RVO is broadly classified into six clinical entities includes (1 Non - ischemic CRVO (2 Ischemic CRVO (3 Non ischemic HCRVO (4Ischemic HCRVO (5 Major BRVO (6Macular BRVO. So much of confusion still exists regarding its natural histo ry, degree of severity, management and its progression. The clinical study of RVO is taken up mainly with a view to study the importance of systemic risk factors in etiopathogenisis of RVO, to study the clinical features and effectiveness of treatment in m odification of the natural course and complications of RVO. Depending on type of venous occlusion patient may present with loss of central vision frequently noticed on waking up in the morning, or field contraction, erythropsia, floates, black spots. Episo des of amaurosis fugax lasts for minutes to hours may be present. There may be metamor - phopsia. Signs of decreased visual acuty, RAPD, visual field defects are observed. Fundus picture shows Retinal hemorrhages distributed based on type of venous occlusion . In ischemic CRVO the picture shows “berries on a twig”. Various sequel & complications include macular edema, anterior segment and retinal neovascularisation, vitreous hemorrhage, retinal detachment may be encountered. Various risk factors include Hypert ension, Diabetes, Hyper lipidemia, IHD

    1987-10-01

    The radiobiology of osteoradionecrosis is a complex of cellular death and cellular functional impairments from radiation energy transfers. Four studies of irradiated patients and a data base from 536 patients with osteoradionecrosis revealed separate pathophysiologic conditions for osteoradionecrosis induced by early trauma, osteoradionecrosis induced by late trauma, and spontaneous osteoradionecrosis. A large body of data suggested useful clinical guidelines for the management of irradiated patients. The guidelines, in part, include a recommendation for deferring radiation treatment for 21 days after tissue wounding, if possible; a relative contraindication to wounding tissue during a radiation course; a recommendation for the use of hyperbaric oxygen before wounding; and a strong recommendation to provide comprehensive dental care to the irradiated patient.

    2002-01-01

    Telomerase activity was detected with both telomeric repeat amplification protocol (TRAP) - silver stain and polymerase chain reaction (PCR) - enzyme linked immuno - sorbent assay (ELISA). We have studied the telomerase activity in the 68 gastric tumors and their neighboring tissues,25 gastric ulcer, and 3 tumor cell colonies. The positive rate of telomerase activity in gastric tumors was 86.8% (59/68) and which was obviously higher than 7.3% (5/68) in the normal tissues adjacent to the tumors and 4% (1/25) in gastric ulcer. The telomerase activity was 100% (3/3) in the tumor colonies. It allowed to be seen that higher telomerase activity was associated with the origin and development of the gastric tumor. We believe that telomerase activity may be a useful clinical diagnostic marker for the gastric tumor.

    2003-01-01

    We present 13 cases of oral mucous membrane pemphigoid (MMP) and review the literature. The cases were retrieved from the archives of Ondokuz Mayis University and Gülhane Military Medical Academy, Turkey, between 1997 and 2002. Inclusion criteria were clinical findings of oral MMP verified by histological and immunofluorescent examination. Thirteen patients (two males and 11 females), aged 16-72 years, were identified. Involvement was confined to the mouth in all cases except one, in which the conjunctiva was also affected. Two individuals in the study were < 20 years old, an age group rarely affected. The oral mucosa is often the initial site of MMP lesions, so it is important that dentists as well as physicians are aware of the symptoms and signs. A swift diagnosis, made in consultation with other specialists such as ophthalmologists and dermatologists, is needed in order to prevent a delay in treatment. PMID:12964512

  11. Clinical studies of lung cancer of atomic bomb survivors, 4

    International Nuclear Information System (INIS)

    A comparative study was made on complications of lung cancer in 188 A-bomb survivors (group 1) and 327 non-exposed patients (group 2) treated from 1972 through 1982. The incidence of complications was higher in group 1 (32 %) than in group 2 (20 %). Complications occurred most frequently in the respiratory system, followed by those in the circulatory system and diabetes mellitus in both groups. Patients with complications in the respiratory, circulatory, or nervous system tended to be inoperable. For patients with clinical stage I or II developing complications, the prognosis was worse as compared with those without complications. Long-term survival can be achieved in two patients with early stage lung cancer in whom surgical treatment was impossible because of the association of severe complications. (Namekawa, K.)

  12. Experimental and clinical studies on the intrahepatic I-131-Lipiodol

    International Nuclear Information System (INIS)

    I-131-Lipiodol, a new therapeutic agent, has been used in the treatment of hepatocellular carcinoma (HCC) since Lipiodol retains within the vascular HCC following intrahepatic arterial injection. Radioiodination of Lipiodol was achieved by using a simple exchange method and the agent was used for the treatment of HCC following the biodistribution studies in dogs and human subjects. Desired radiation doses and easily be delivered up to 12,000 rad while keeping the radiation doses to normal liver, lung and whole body safe and tolerable. Clinical studies in 50 patients with hepatoma were performed by this method in order to estimate the therapeutic effect, safety, indication and limitations. The results as follows: 1. Biodistribution studies The effective half life of I-131-Lipiodol in the tumor was 6 days and retained in the tumor as long as 3 months. About 10% of radioactivity was demonstrated in the lungs with effective half life decay. The I-131-Lipiodol in the normal liver tissue seems to be metabolized in the hepatocytes and excreted into the bile and urine. No demonstrable radioactivity was noted in the thyroid, bowels, spleen and bone marrow. 2. Histologic studies Histologic studies following the untrahepatic I-131-Lipiodol of the canine liver revealed the Lipiodol particles in the bile duct cells and cytoplasm of hepatocytes. In human resected hepatomas after I-131-Lipiodol infusion, Lipiodol droplets were demonstrated in the tumor vessels, sinusoids as well as in the tumor cell cytoplasm. Extensive hemorrhagic necrosis of tumor was demonstrated after treatment with I-131-Lipiodol. 3. Clinical studies Response rate was most prominent in those cases of single massive types which measures less than 5cm in diameter. Multinodular type was also responsive rather than single massive type, however, infiltrative type of tumor or the tumors measuring more than 8cm was less effective on this therapy. 4. Adverse reactions Adverse reactions from the procedure include

    Full Text Available Abstract Background Traditional peripheral biofeedback has grade A evidence for effectively treating migraines. Two newer forms of neurobiofeedback, EEG biofeedback and hemoencephalography biofeedback were combined with thermal handwarming biofeedback to treat 37 migraineurs in a clinical outpatient setting. Methods 37 migraine patients underwent an average of 40 neurofeedback sessions combined with thermal biofeedback in an outpatient biofeedback clinic. All patients were on at least one type of medication for migraine; preventive, abortive or rescue. Patients kept daily headache diaries a minimum of two weeks prior to treatment and throughout treatment showing symptom frequency, severity, duration and medications used. Treatments were conducted an average of three times weekly over an average span of 6 months. Headache diaries were examined after treatment and a formal interview was conducted. After an average of 14.5 months following treatment, a formal interview was conducted in order to ascertain duration of treatment effects. Results Of the 37 migraine patients treated, 26 patients or 70% experienced at least a 50% reduction in the frequency of their headaches which was sustained on average 14.5 months after treatments were discontinued. Conclusions All combined neuro and biofeedback interventions were effective in reducing the frequency of migraines with clients using medication resulting in a more favorable outcome (70% experiencing at least a 50% reduction in headaches than just medications alone (50% experience a 50% reduction and that the effect size of our study involving three different types of biofeedback for migraine (1.09 was more robust than effect size of combined studies on thermal biofeedback alone for migraine (.5. These non-invasive interventions may show promise for treating treatment-refractory migraine and for preventing the progression from episodic to chronic migraine.

    Full Text Available Abstract Objective Few methodological studies address the prioritization of clinical topics for the development of Clinical Practice Guidelines (CPGs. The aim of this study was to validate a methodology for Priority Determination of Topics (PDT of CPGs. Methods and results Firstly, we developed an instrument for PDT with 41 criteria that were grouped under 10 domains, based on a comprehensive systematic search. Secondly, we performed a survey of stakeholders involved in CPGs development, and end users of guidelines, using the instrument. Thirdly, a pilot testing of the PDT procedure was performed in order to choose 10 guideline topics among 34 proposed projects; using a multi-criteria analysis approach, we validated a mechanism that followed five stages: determination of the composition of groups, item/domain scoring, weights determination, quality of the information used to support judgments, and finally, topic selection. Participants first scored the importance of each domain, after which four different weighting procedures were calculated (including the survey results. The process of weighting was determined by correlating the data between them. We also reported the quality of evidence used for PDT. Finally, we provided a qualitative analysis of the process. The main domains used to support judgement, having higher quality scores and weightings, were feasibility, disease burden, implementation and information needs. Other important domains such as user preferences, adverse events, potential for health promotion, social effects, and economic impact had lower relevance for clinicians. Criteria for prioritization were mainly judged through professional experience, while good quality information was only used in 15% of cases. Conclusion The main advantages of the proposed methodology are supported by the use of a systematic approach to identify, score and weight guideline topics selection, limiting or exposing the influence of personal biases

    Full Text Available Abstract Background There has been an increased interest in recruiting health professionals with a clinical background to management positions in health care. We know little about the factors that influence individuals’ decisions to engage in management. The aim of this study is to explore clinicians’ journeys towards management positions in hospitals, in order to identify potential drivers and barriers to management recruitment and development. Methods We did a qualitative study which included in-depth interviews with 30 clinicians in middle and first-line management positions in Norwegian hospitals. In addition, participant observation was conducted with 20 of the participants. The informants were recruited from medical and surgical departments, and most had professional backgrounds as medical doctors or nurses. Interviews were analyzed by systemic text condensation. Results We found that there were three phases in clinicians’ journey into management; the development of leadership awareness, taking on the manager role and the experience of entering management. Participants’ experiences suggest that there are different journeys into management, in which both external and internal pressure emerged as a recurrent theme. They had not anticipated a career in clinical management, and experienced that they had been persuaded to take the position. Being thrown into the position, without being sufficiently prepared for the task, was a common experience among participants. Being left to themselves, they had to learn management “on the fly”. Some were frustrated in their role due to increasing administrative workloads, without being able to delegate work effectively. Conclusions Path dependency and social pressure seems to influence clinicians’ decisions to enter into management positions. Hospital organizations should formalize pathways into management, in order to identify, attract, and retain the most qualified talents. Top managers

    Background: The prevalence of sudden sensorineural hearing loss in children (CSSNHL) is consistently increasing. However, the pathology and prognosis of CSSNHL are still poorly understood. This retrospective study evaluated clinical characteristics and possible associated factors of CSSNHL. Methods: One hundred and thirty-six CSSNHL patients treated in Department of Otolaryngology-Head and Neck Surgery and Institute of Otolaryngology at Chinese PLA General Hospital between July 2008 and August 2015 were included in this study. These patients were analyzed for clinical characteristics, audiological characteristics, laboratory examinations, and prognostic factors. Results: Among the 136 patients (151 ears), 121 patients (121 ears, 80.1%) were diagnosed with unilaterally CSSNHL, and 15 patients (30 ears, 19.9%) with bilateral CSSNHL. The complete recovery rate of CSSNHL was 9.3%, and the overall recovery rate was 37.7%. We found that initial degree of hearing loss, onset of treatment, tinnitus, the ascending type audiogram, gender, side of hearing loss, the recorded auditory brainstem response (ABR), and distortion product otoacoustic emissions (DPOAEs) had prognostic significance. Age, ear fullness, and vertigo had no significant correlation with recovery. Furthermore, the relevant blood tests showed 30.8% of the children had abnormal white blood cell (WBC) counts, 22.1% had elevated homocysteine levels, 65.8% had high alkaline phosphatase (ALP), 33.8% had high IgE antibody levels, and 86.1% had positive cytomegalovirus (CMV) IgG antibodies. Conclusions: CSSNHL commonly occurs unilaterally and results in severe hearing loss. Initial severe hearing loss and bilateral hearing loss are negative prognostic factors for hearing recovery, while positive prognostic factors include tinnitus, gender, the ascending type audiogram, early treatment, identifiable ABR waves, and DPOAEs. Age, vertigo, and ear fullness are not correlated with the recovery. Some serologic indicators

    Full Text Available Background: Intestinal stoma is an opening for fecal diversion. The purpose of the present study was to identify indications for commonly performed intestinal stomas and to study complications related to it. Methods: This is a prospective study was carried out in a surgical unit of Hamidia Hospital, Gandhi Medical College, Bhopal from January, 2012 to December,2012. Data was collected by meticulous history taking including age, gender, indication, type of stoma, type of surgery, careful clinical examination, appropriate operative findings and follow up of the cases. The results were collected, analyzed and compared with other studies. Results: A total of 100 patients were evaluated age ranged between 12- 85 years (50.5 ± 29.01 years Male to female ratio was 7:3. Of the 100 patients 97 were admitted in emergency while 3 in out-patient department. The most common type of stoma made was loop ileostomy (64% followed by sigmoid colostomy (11% and transverse loop colostomy (9%. Main indication for a stoma formation was enteric perforation (38% followed by Koch’s abdomen (18%. Of the various complications encountered with intestinal stoma, peristomal skin irritation (36% was the most consistent complication followed by laparotomy wound infection (13%. Conclusions: Inspite of vast exposure of general surgeons towards stoma formation the complications are inevitable. Early detection of complication and its timely management is the keystone.

    Health technology assessments propose to study the differential impact of health interventions in a complex care system which is characterised by the multitude of individual behaviours and the diverse nature of the institutions involved. Current systems for data collection lend themselves poorly to this rigorous analysis of efficacy of treatments in the actual situations where they are used. Randomised trials endeavour to neutralise any parasitic interference which could compromise testing for a causal relationship between the treatment administered and the result obtained. Their methodology which establishes the term ceteris paribus in the principle of good practice lends itself poorly to an analysis of individual behaviour. Observational studies are start from actual treatment situations to describe them as reliably as possible. By definition, however, these assume that the natural course of events is not deviated by any intervention. The absence of an experimental plan increases the likelihood of bias and makes it more difficult to test for causal relationships. They lend themselves poorly to testing for incremental efficacy. The two instruments to be preferred are decisional analysis and quasi-experimental studies. Decisional analysis help to avoid the problems of external validity associated with randomised clinical trials by associating parameters which are extracted from data obtained from everyday practice. Quasi-experimental studies or pragmatic trials are based on the reality of behaviour of the prescriber and his/her patients; their impact on efficacy, quality of life social costs of the disease and of treatments may be identified under normal conditions of use.

    Full Text Available This study was conducted on 390 female breast cancer patients and an equal number of females as controls. The patients were attending some University and Teaching Hospitals in Cairo and Assuit. Ninety of them were newly operated. A retrospective, case-control, clinic based study was chosen to carry out this research. The aim of the study was to describe the sociodemographic, characteristics and clinical features of female breast cancer and to determine its risk factors among Egyptian women. All the patients and the controls had undergone physical examinations. Laboratory investigations were done for the newly operated patients and their controls. The most important characteristics of breast cancer patients were breast mass as the main presenting symptom (92.1% and treated by modified radical mastectomy (77.2%. Low means level of serum vitamin D and high levels of serum cholesterol and triglyceride were found more among the patients. Age at first full term pregnancy 30 years, age at menopause 45 years, pregnancy termination and/or abortion and never married were important gynaecological and reproductive risk factors (OR=4.44, 3.14, 2.84 and 2.67, respectively. Also, exposure to radiation and/or environmental factors, history of benign breast disease and alcohol use were important associated risk factors (OR=5.05, 4.63 and 4.10, respectively. Moreover, the sister as the nearest female relative with breast cancer, total number of female relatives with breast cancer 2 and relative(s age at diagnosis <50 years were important family history risk factors (OR=9.19, 8.84 and 7.91, respectively. Lastly, high consumption of canned foods, fat rich foods and low consumption of fresh fruits and vegetables were important dietary risk factors (OR=3.39, 1.76 and 1.51, respectively.

    The use of plasmid DNA as vaccines for the treatment of cancer and infectious diseases is on the rise. In order to facilitate the manufacture of clinical-grade plasmid DNA for Phase I clinical trials, we developed a process whereby >200 mg plasmid could be produced in a single production run under Good Manufacturing Practices. A dedicated cleanroom (Class 10,000 with Class 100 biosafety cabinet) is utilized for production of the bacterial cell bank, fermentation, harvest/lysis of the biomass, and downstream purification. Fermentation requires three 16-18 h runs (approximately 12 L each) in shaker-flasks, yielding approximately 60 g bacterial paste following batch centrifugation. The biomass is alkaline-lysed, pooled, and the resulting flocculent precipitate is separated by a novel vacuum step, followed by depth-filtration. Downstream processing includes anion-exchange chromatography, utilizing Qiagen silica-based resin, and precipitation with isopropanol. Following precipitation, the DNA is harvested by centrifugation, dried, formulated, and sterile-filtered using a Sartorius Sartobran 150 filter prior to Final-Filling. All processing steps utilize sterilized, single-use components. This process results in a product manufactured according to regulatory guidelines. The plasmid DNA is sterile with >or=95% supercoiled DNA, an A260/A280 ratio>or=1.9, undetectable or extremely low residual endotoxin, RNA, genomic DNA, protein, and antibiotic. Residual solvent levels are negligible. The product yields the predicted profile upon restriction-enzyme digestion, is biologically active upon transfection and remains stable for several years at -20 degrees C. We have therefore developed a reproducible and cost effective process to manufacture clinical-grade plasmid DNA. This process can be adapted by other academic centers for human or large animal clinical trials. PMID:17537555

    Full Text Available Rhinoplasty is one of the most common cosmetic surgery performed by the otorhinolaryngologists. The main indication for rhinoplasty is cosmetic or functional or both. In regard to paucity of research regarding patient satisfaction after surgery, we have done this prospective clinical study in our hospital. 40 patients were included in the study from January 2012 to December 2012. Rhinoplasty Outcomes Evaluation (ROE Questionnaire was applied to all the patients and evaluation of the satisfaction pre op and post operatively was assessed and the results were statistically analysed. The age of the study group ranged from 20 yrs to 39 yrs with the mean age of 24.85 +/- 3.43 years. The average satisfaction mark of patients undergoing rhinoplasty in pre-operative state was 28.05 & post-operative it improved and reached to 67.91.The average satisfaction of female were 26.75 preoperatively reached to 63.68 postoperatively. The average satisfaction of male were 31.2 preoperatively reached upto 67.91 post operatively. The degree of the satisfaction pre and post operatively was compared using student t test and paired t test. It was 67.91 in males and 36.53 among females which was statistically significant (p < 0.05. Patient satisfaction is as important as technical aspects of rhinoplasty. Hence a novel attempt is made in this direction to assess and understand patient expectations to achieve realistic goals in rhinoplasty.

  8. Indium-111 labelled platelets: experimental and clinical studies

    International Nuclear Information System (INIS)

    The object of the present study became to develop a method of effective and gentle isolation and 111-In labelling of human platelets, as well as to employ these platelets in human clinical studies with the object of elucidating a number of physiological and pathophysiological mechanisms and processes in which platelets take part. 111-In-oxine presents obvious advantages over 51-Cr-sodium chromate; a high labelling efficiency, and more advantageous physical properties (a half life of 68 hours (against the half life of 28 days for 51-Cr) and considerably more effective gamma emission), making external registration by means of a gamma camera possible. Considering the role played by platelets in the development of atherosclerosis and its thromboembolic complications, in the early phases of deep venous thrombosis, and in graft rejection, it is natural that attempts have been made to use 111-In-labelled platelets for scintigraphic and kinetic evaluation of thromboembolic processes. Accumulation of 111-In-labelled platelets at sites of vessel wall injury, on pulmonary emboli (presumably on deep vein thrombi as well), and on catheter material has been demonstrated. Beyond this, the number of publications concerning the use of 111-In-labelled platelets for visualization of atherosclerosis, venous thromboembolism, arterial grafts, intracardiac thrombi, aortic aneurysms, renal allograft rejection, and other situations in which platelet thromboembolism takes place, provides evidence that a tool has finally been found for the study of their nature and response to therapeutic intervention.

    Leptospirosis is a severe spirochetal zoonosis in the world. It is considered an occupational disease of persons engaged in agriculture, sewage works, forestry, and animal slaughtering. A study was conducted with an objective of assessing the seroprevalence of leptospirosis in and around Vellore district, Tamil Nadu. The study was based on the signs and symptoms of the patients reporting fever in Vellore Municipal Clinic (Urban Malarial Scheme). Blood samples were collected from 129 patients. Animal studies were conducted from 24 rodents captured form the market place of the Vellore municipality. In the ZET (Zonal Entomological Team, Vellore) Laboratory the sera were examined by macroscopic slide agglutination test (MSAT). In the MAST, totally 10 positive leptospiral cases from human beings and 10 positive leptospiral cases from rats (Rattus rattus and Rattus norvegicus) were found out. Then both positive cases of leptospiral vials were labeled, sealed, and sent to the Leptospirosis Research Laboratory, Madhavaram, Chennai, for further serovars examination. Among the various serovars identified autumnalis was more prevalent. Our findings showed that the age groups between 15 and 55 years showed more susceptibility. Particularly the adults were more infected. The majority of seropositive individuals in the cases had only subclinical infection. Rodents were abundant and contributed to enzootic and endemic prevalence of leptospirosis. PMID:25050124

    Full Text Available Introduction Nosocomial infections (NIs are a serious health problem in hospitals worldwide and are followed by a series of consequences, medical, judicial, ethical and economic. Objective The main aim of this study was to assess the magnitude of NIs at the Clinical Centre in Kragujevac. Methods A prevalence study of nosocomial infections was conducted from 16th till 20th May, 2005, within Second National Prevalence Study of Niš in the Republic of Serbia. Results The study included 866 patients. 40 patients had a NI, thus the prevalence of patients with NIs and prevalence of NIs was the same, 4.6%. Among NIs, the most frequent were urinary infections (45.0% followed by surgical-site infections (17.5%, skin and soft tissue infections (15% and pneumonia (12.5%. The rate of NIs was highest at departments of orthopaedics and traumatological surgery (12.0%, followed by intensive care units (8.0%. Overall, 67.5% (27/40 NIs were culture-proved; the leading pathogens were Escherichia coli (40.0%, followed by gram-negative bacteria (Pseudomonas species, Proteus mirabilis, Enterobacteriaceae with equal frequency of 8.0%. Nosocomial infections were significantly more frequent in patients aged ≥65 years (p<0.05, with longer hospitalization ≥8 days (p<0.00, in intensive care patients (p<0.05, patients with an intravenous catheter (p<0.00, urinary catheter (p<0.00, and those under antibiotic therapy (p<0.00. Conclusion This study showed that the prevalence of nosocomial infections in our hospital is similar to the prevalence in the developed countries. The study of prevalence provides a prompt insight into basic epidemiological and ethiological characteristics of nosocomial infections, hence identification of hospital priorities and the need to undertake appropriate prevention measures. .

Methods: We employed an explorative qualitative research design by conducting focus group discussions with 41 pediatric postgraduate trainees at the College of Health Science, Makerere University. A semi-structured tool was used to obtain the views and experiences of the trainees. Transcripts from the discussion were analyzed in an iterative manner using thematic content analysis. Results: The trainees reported the OSCEs as a fair and appropriate tool for assessing clinical competency at the postgraduate level. However, they noted that whereas OSCEs assess a broad range of skills and competencies relevant to their training, there were areas that they did not adequately assess. In particular, OSCEs did not adequately assess in-depth clinical knowledge or detailed history-taking skills. Overall, the majority of the trainees reported that the OSCEs inspired them to study widely and improve their procedural and communication skills. Conclusion: OSCEs are a useful tool for assessing clinical competencies in postgraduate education. However, the perceived limitations in their ability to assess complex skills raises concerns about their use as a standalone mode of assessment at the postgraduate level. Future studies should evaluate how use of OSCEs in

    Full Text Available Background: Topical corticosteroids were first introduced for use in 1951. Since then uncontrolled use (abuse has caused many different reactions resembling rosacea - steroid dermatitis or iatrosacea. Multiple pathways including rebound vasodilatation and proinflammatory cytokine release have been proposed as the mechanism for such reactions. Aim: The aim was to study the adverse effects of topical steroid abuse and the response to various treatment modalities. Materials and Methods: Two hundred patients with a history of topical steroid use on face for more than 1 month were studied clinically and various treatments tried. Results: The duration of topical corticosteroid use varied from 1 month to 20 years with an average of 19.76 months. Majority of patients were using potent (class II topical steroids for trivial facial dermatoses. The common adverse effects were erythema, telangiectasia, xerosis, hyperpigmentation, photosensitivity, and rebound phenomenon. No significant change in laboratory investigations was seen. Conclusion: A combination of oral antibiotics and topical tacrolimus is the treatment of choice for steroid-induced rosacea.

    Fifty seven patients (42 males and 15 females) with non-compressive myelopathy were studied from 1997 to 1999. Acute transverse myelitis (ATM) was the commonest (31) followed by Vit B12 deficiency myelopathy (8), primary progressive multiple sclerosis (5), hereditary spastic paraplegia (3), tropical spastic paraplegia (2), subacute necrotising myelitis (1), radiation myelitis (1), syphilitic myelitis (1) and herpes zoster myelitis (1). 4 cases remained unclassified. In the ATM group, mean age was 30.35 years, antecedent event was observed in 41.9% case, 25 cases had symmetrical involvement and most of the cases had severe deficit at onset. CSF study carried out in 23 patients of ATM revealed rise in proteins (mean 147.95mg%, range 20-1200 mg/dL) and pleocytosis (mean 20.78/cumm, range 0-200 mm3). Oligoclonal band (OCB) was present in 28% of cases of ATM. The most common abnormality detected was a multisegment hyperintense lesion on T2W images, that occupied the central area on cross section. In 6 patients hyperintense signal was eccentric in location. MRI was normal in 4 cases of ATM. Thus ATM is the leading cause of non-compressive myelopathy. Clinical features combined with MRI findings are helpful in defining the cause of ATM. PMID:10625902

    OBJECTIVE: To explore the clinical and neuroelectrophysiological features of patients with corticobasal degeneration(CBD). BACKGRUND: To date, there is no systematic presentation of patients diagnosed as CBD in our country. METHODS: 29 patients with CBD were examined symptoms, signs, CT/MRI, SPECT and electrophysiologic studies in detail. RESULTS: The results demonstrated asymitrical Parkinsonian manifestations were present in all, cortical dysfunction in 86%. other movement disorders in 75%, 21 cases showed asymmetrical atrophy in CT/MRI and 25 in SPECT were hypoperfused on the fronto-parital regions contralateral to the affected limbs 19 cases in EEG showed asymitrical slow waves; Surface EMG showed .that myoclonus in 15 occurred on the action; SEPs revealed c-reflexes enhanced and without giant SEP; patients had no pre-myoclonus spike on JLA. 29 patients showed normal CMCT in MEPs. DISCUSSION: The most common manifestation of CBD was asymmetric Parkinsonian features, followed by cortical dysfunction and other movement disorders. Brain imaging showed fronto-parietal abnormalities contralateral to the affected side. The study of electrophysiology showed enhanced cortical excitability and pyramidal tract intact. CONCLUSION: CBD is characterazed by a slowly progressive disease with both cortical and basal ganglionic dysfunction.

    Full Text Available BACKGROUND : Forefoot eczema (FE is characterized by dry fissured dermatitis of the plantar surface of the feet. AIM : To study the clinical profile of FE and the possible etiological factors. METHODS : Forty-two patients with FE were included in the study. A detailed history was recorded and examination done. Fungal scrapings and patch test with Indian Standard Series (ISS were performed in all patients. RESULTS : The most common site affected was the plantar surface of the great toe in 16 (38.09% patients. Hand involvement, with fissuring and soreness of the fingertips and palm, was seen in four patients (9.5%. Seven patients (16.6% had a personal history of atopy whereas family history of atopy was present in six (14.2%. Seven patients (16.6% reported aggravation of itching with plastic, rubber or leather footwear, and 13 (30.9%, with detergents and prolonged contact with water. Negative fungal scrapings in all patients ruled out a dermatophyte infection. Patch testing with ISS was performed in 19 patients and was positive in five. CONCLUSIONS : FE is a distinctive dermatosis of the second and third decade, predominantly in females, with a multifactorial etiology, possible factors being chronic irritation, atopy, footwear and seasonal influence.

    Tacrolimus is a macrolide T cell immunomodulator that is used in myasthenia gravis (MG) patients to affect muscle contraction (ryanodine receptor by modulating intracellular calcium-release channels and increasing muscular strength), glucocorticoid receptors (increasing intracellular concentration of steroids and blocking the steroid export mechanism), and an increase in T cell apoptosis. In this study, we report the results of low-dose tacrolimus (0.1 mg/kg/day) treatment in 212 MG patients. There were 110 thymectomized, cyclosporine- and prednisone-dependent patients; 68 thymectomized patients who started tacrolimus early postoperatively (24 h after operation); and 34 patients over 60 years old with nonthymomatous generalized MG or in whom thymectomy was contraindicated. The mean follow-up time was 49.3 +/- 18.1 months. Muscular strength showed an increase of 23% after 1 month of treatment and 29% at the end of the study. The acetylcholine receptor antibodies decreased significantly from a mean of 33.5 nmol/L at base line to 7.8 nmol/L at the final visit. In the thymectomy group with combined prednisone and tacrolimus stratified by histology of the thymus, the mean probability to attain complete stable remission at 5 years was 80.8% in patients with hyperplasia, 48.1% in thymic involution, and 9.3% in patients with thymoma. In 4.9% of patients, tacrolimus was withdrawn because of major adverse effects. Our results suggest that a low dose of tacrolimus is effective for MG and could be included to the armamentarium for this autoimmune disease. The present results should be interpreted considering the limitations of a retrospective clinical study. Confirmation of these results in randomized studies is desirable. PMID:18096852

  2. Phase I study of intravenous iododeoxyuridine as a clinical radiosensitizer

    International Nuclear Information System (INIS)

    Twenty-four patients with locally advanced (19 patients) or metastatic (5 patients) tumors were treated in a Phase I study combining constant intravenous infusions of iododeoxyuridine (IUdR) and hyperfractionated radiation therapy. IUdR was given as a constant infusion for 12 hours/day for two separate 14-day infusion periods in most patients. The dose of IUdR was escalated from 250 to 1200 mg/m2/12-hour infusion in this study. The initial tumor volume was treated to 45 Gy/1.5 Gy BID/3 weeks followed by a cone-down boost to 20-25 Gy/1.25 Gy BID/2 weeks after a planned 2-week break. THe IUdR infusion preceded the initial and cone-down irradiation by 1 week. Local acute toxicity (within the radiation volume) was uncommon and few patients required an alteration of the planned treatment schedule. Two patients developed late local toxicity with one patient showing clinical signs of radiation hepatitis and another patient developing a large bowel obstruction that required surgical bypass. Dose-limiting systemic toxicity was confined to the bone marrow with moderate to severe thrombocytopenia developing on Day 10-14 of infusions at 1200 mg/m2/12 hours. Mild stomatitis and partial alopecia occurred in some patients at this dose level. No systemic skin toxicity was seen. Pharmacology studies revealed steady-state arterial plasma levels of IUdR of 1 to 8 X 10(-6) M over the dose range used. In vivo IUdR incorporation into tumors was studied in three patients with high-grade sarcomas using an anti-IUdR monoclonal antibody and immunohistochemistry and demonstrated incorporation in up to 50-70% of tumor cells. The preliminary treatment results, particularly in patients with unresectable sarcomas, are encouraging

    Participant accrual into research studies is critical to advancing clinical and translational research to clinical care. Without sufficient recruitment, the purpose of any research study cannot be realized; yet, low recruitment and enrollment of participants persist. StudySearch is a web-based application designed to provide an easily readable, publicly accessible, and searchable listing of IRB-approved protocols that are accruing study participants. The Regulatory, Recruitment and Biomedical Informatics Cores of the Center for Clinical and Translational Science (CCTS) at The Ohio State University developed this research study posting platform. Postings include basic descriptive information: study title, purpose of the study, eligibility criteria and study personnel contact information. Language concerning benefits and/or inducements is not included; therefore, while IRB approval for a study to be listed on StudySearch is required, IRB approval of the posted language is not. Studies are listed by one of two methods; one automated and one manual: (1). Studies registered on ClinicalTrials.gov are automatically downloaded once a month; or (2). Studies are submitted directly by researchers to the CCTS Regulatory Core staff. In either case, final language is a result of an iterative process between researchers and CCTS staff. Deployed in January 2011 at OSU, this application has grown to approximately 200 studies currently posted and 1500 unique visitors per month. Locally, StudySearch is part of the CCTS recruitment toolkit. Features continue to be modified to better accommodate user behaviors. Nationally, this open source application is available for use.

    Human studies, encompassing interventional and observational studies, are the most important source of evidence for advancing our understanding of health, disease, and treatment options. To promote discovery, the design and results of these studies should be made machine-readable for large-scale data mining, synthesis, and re-analysis. The Human Studies Database Project aims to define and implement an informatics infrastructure for institutions to share the design of their human studies. We have developed the Ontology of Clinical Research (OCRe) to model study features such as design type, interventions, and outcomes to support scientific query and analysis. We are using OCRe as the reference semantics for federated data sharing of human studies over caGrid, and are piloting this implementation with several Clinical and Translational Science Award (CTSA) institutions.

    Full Text Available Although urinary tract infections (UTI represent the most common infection caused by enterococci, some aspects remain to be fully clarified. The aim of this study was to determine the clinical characteristics present in UTI caused by Enterococcus spp. in patients followed up at the Prof. Edgard Santos Teaching Hospital of the Federal University of Bahia. All patients consecutively examined between 1997 and 2005, who received a diagnosis of UTI caused by Enterococcus spp. were included in the study. UTI was defined as the presence of 10(5 colony-forming units per mL of urine. Standard microbiological techniques were used. During the study period, 6.2% of the urine cultures were positive for Enterococcus spp. The mean age of the patients was 48.9 years and 57% were male. At initial evaluation, 13% of the patients had complaints suggestive of UTI. Nineteen patients had a history consistent with obstructive uropathy and 26 with neurogenic bladder. At final evaluation, UTI was the diagnosis in 48 patients. In 36 patients (29%, the primary diagnosis was related to urogenital diseases, consisting of obstructive uropathy in 23 of these cases, while in 32 patients (25.8% primary diagnosis was related to neurologic diseases, frequently neurogenic bladder. UTI caused by Enterococcus spp. is not infrequent, is usually associated with few or no symptoms and occurs in sick patients who have anatomical or functional obstructive uropathy associated or not with urinary tract catheterization or instrumentation. The diagnosis of enterococcal UTI may indicate a urinary tract abnormality yet to be diagnosed.

Methods: An anonymous online survey (SurveyMonkey™ was developed to evaluate demographics of the program, clinic organization, and patient and preceptor characteristics, and to compare fellow satisfaction when fellows were the primary providers with faculty supervision versus attending-run clinics assisted by fellows or a combination of the two models. Pediatric subspecialty fellows in a 3-year Accreditation Council for Graduate Medical Education accredited program in the United States (excluding emergency medicine, neonatology, and critical care were invited to participate. Results: There were 644 respondents and nearly half (54% of these had fellow-run clinics. Eighty-six percent of fellows responded that they would prefer to have their own continuity clinics. Higher satisfaction ratings on maintaining continuity of care, being perceived as the primary provider, and feeling that they had greater autonomy in patient management were associated with being part of a fellow-run clinic experience (all P < 0.001. Additionally, fellow-run clinics were associated with a feeling of increased involvement in designing a treatment plan based on their differential diagnosis (P < 0.001. There were no significant associations with patient or preceptor characteristics. Conclusion: Fellow-run continuity clinics provide fellows with a greater sense of satisfaction and independence in management plans.

    Full Text Available INTRODUCTION Perforated duodenal ulcer, the most catastrophic complication was Associated with high mortality in the past due to late presentation of the patients, delay in surgery and lack of antibiotics. Various authors state that the incidence of peptic ulcer disease and perforation has been declining for the past 3 decades. Because of advances in the medical therapy of peptic ulcer with a wide range of drugs the management of peptic ulcer disease has been changing and the role of surgery has been declining. Perforation is usually seen in 3rd and 4th decades with a male preponderance and the epidemiological trend is not the same worldwide. Incidence is slightly declining in western countries. The present study has been done during the period between 2013 and 2014 in S. V. R. R. Government general hospital Tirupati. AIMS AND OBJECTIVES The aim of the present study is to analyze the probable factors for increase in incidence of duodenal ulcer perforation, with particular emphasis on assessment of impact of H2 receptor antagonists and Proton Pump inhibitors on the incidence of perforation. STUDY SETTING S. V. Medical College, Department of General Surgery, Tirupati. STUDY PERIOD Patients attending S. V. Medical College, Department of General Surgery with perforation during the period from November 2013 to October 2014.

    International Nuclear Information System (INIS)

    Nuclear cardiology, nuclear oncology, pediatric nuclear medicine and nuclear endocrinology are the main application areas of clinical nuclear medicine in Turkey. Not only imaging studies, but also therapeutic application of radiopharmaceuticals is also performed at many institutes, such as hyperthyroidism treatment with radioiodine, thyroid cancer ablation and metastases treatment with radioiodine, radio synovectomy, metastatic pain therapy, and recently radioimmunotherapy of lymphomas. Almost all radionuclides and radiopharmaceuticals are obtained commercially from European countries, except 18-FDG which is obtained from two cyclotrons in Turkey. More than 30.000 renal procedures are performed at the University hospitals in a year. Pediatric age groups is approximately % 55 of patients. 99mTc-DTPA (%44), 99mTc-DMSA (%37), 99mTc-MAG3 (%17) and 99mTc-EC (%2) are the most commonly used radiopharmaceuticals for renal imaging. More than 6.000 vials of several pharmaceuticals are used for renal cortical scintigraphy (%35), dynamic renal imaging (%34), renal scintigraphy with diuretic (%27) and captopril scintigraphy (%4). Most common indication for renal cortical scintigraphy is detection of cortical scarring (%53). In addition, using single plasma sample method or gamma-camera method renal clearance measurements with 99mTc-MAG3 99mTc-DTPA have been used at some institutions. (author)

    International Nuclear Information System (INIS)

    A phase I clinical study on 99mTc-hexakis 2-methoxy isobutylisonitrile (99mTc-MIBI) was carried out in 6 normal volunteers. There was no significant change in vital signs and laboratory parameters attributing to the reagent other than complaint of slight and transient metallic taste immediately after the injection in 4 volunteers. The highest dosimetry was calculated as 1.1 mGy/37 MBq at lower large intestine, which was within the acceptable range. 99mTc-MIBI was rapidly cleared from the blood and accumulated in the heart immediately after the injection with 1.4% dose and 1.8% dose at 5 min at rest and at stress, respectively. The retention of radioactivity in the heart well continued for at least several hours. The heart-to-lung ratio was over 2.00 at 5 min and heart-to-liver ratio was over 1.00 at 60 min. Myocardial planar and SPECT images were obtained with high quality. In conclusion, 99mTc-MIBI is a useful myocardial perfusion imaging agent. (author)

    Full Text Available The repair and regeneration of tissue is a well-discussed topic. Over the past 20 years, with the development of genetics, auxology, stem cell biology, and tissue engineering, tissue repair and regeneration have rapidly developed as emerging "Regenerative Medicine". Regenerative medicine has significant market demand in China. Based on national statistics, injury and poisoning patients rank third in afflictions in city hospitals (accounting for 9.13% and rank second in afflictions in county hospitals (accounting for 14.07%. Totally, approximately one hundred million patients suffered from traumatic, genetic and metabolic diseases in China and demand reparative and regenerative medical treatment each year. The Chinese government and its related departments have always attached great importance and support to the development of regenerative medicine, and the Chinese academic circle is involved in a very wide range of diseases and injuries including regenerative medical theory and technology. Stem cell biology, organ engineering and duplication, tissue engineering research and production have developed rapidly, and great portion of these studies have started to appear in applications, which have aroused extensive concerns in international professional circle. In the next 10 years, the Chinese regenerative medical system will be further improved, in both statute and rules, clinical translation will be further accelerated. Breakthroughs are expected in induced differentiation of stem cells and synchronous repair and regeneration of multiple organs, construction of major organs by tissue engineering, large-scale applications of tissue engineering products, and other aspects.

    Radiation therapy is an effective treatment for cancer, however, irradiation of the chest may cause radiation pneumonitis as a severe pulmonary complication. Although this condition is responsive to steroid therapy, it is well known that therapy is an increased vulnerability to various infections in patients receiving long-term steroid therapy and exacerbation of the disease associated with a reduction in the dose. In this study, 10 patients with radiation pneumonitis received 3 divided daily oral of 0.9{similar to}1.2 g/day (15 mg/kg) of sulpyrin. The patients' fever disappeared within a few days after the beginning of treatment. Pneumonitis was roentgenographically stabilized, although the fibrotic and atrophic changes continued. No exacerbation of the disease was observed even after discontinuation of the therapy and the outcomes of all patients was satisfactory. These results suggest that sulpyrin was clinically effective for radiation pneumonitis, probably resulting from an anti-inflammatory effect due to prostaglandin synthesis inhibition. In the acute phase of radiation pneumonitis, the introduction of steroids appears to be delayed. This sulpyrin therapy may be a useful alternative for cases in which the steroid therapy in contraindicated. (author).

    Pulsed-field gel electrophoresis is a method applied in separating large segments of deoxyribonucleotide using an alternating and cross field. In a uniform magnetic field, components larger than 50kb pass a route through the gel and since the movement of DNA (Deoxyribonucleic acid) molecules are in a Zigzag form, separation of DNAs as bands carried out better via gel. PFGE in microbiology is a standard method which is used for typing of bacteria. It is also a very useful tool in epidemiological studies and gene mapping in microbes and mammalian cell, also motivated development of large-insert cloning system such as bacterial and yeast artifical chromosomes. In this method, close and similar species in terms of genetic patterns show alike profiles regarding DNA separation, and those ones which don't have similarity or are less similar, reveal different separation profiles. So this feature can be used to determine the common species as the prevalence agent of a disease. PFGE can be utilized for monitoring and evaluating different micro-organisms in clinical samples and existing ones in soil and water. This method can also be a reliable and standard method in vaccine preparation. In recent decades, PFGE is highly regarded as a powerful tool in control, prevention and monitoring diseases in different populations. PMID:26894068

  17. Clinical study on the computed tomographic diagnosis of intestinal diseases

    International Nuclear Information System (INIS)

    The CT diagnosis of intestinal diseases was evaluated in 140 patients. The results were as follows. 1) In the basic study on the contrast material for CT of intestinal tract examined by using experimental tumor model and cow's colon, olive oil showed highest evaluation as a contrast material. 2) Clinically, It was suggested that olive oil was most useful as a contrast material for CT of rectum and sigmoid colon and tepid water was available for small intestine, large intestine except for sigmoid colon and rectum. 3) CT examination of colon was done on 94 patients with colon malignant tumor. CT findings were compared with pathological findings, and diagnostic criteria of CT for the detection of the degree colon wall invasion was made. 4) Diagnostic accuracy of CT for swollen lymphonodes showed high rate in the para-rectal and para-aortic lymphonodes region. On the other hand, diagnostic accuracy for mesenteric dissemination of malignant tumor was low except for massive ascites. 5) CT was also useful for detection of the extraluminal lesion in inflammatory intestinal disease.

  18. A simplified method for the clinical study of protein turnover

    International Nuclear Information System (INIS)

    The determination of turnover rate of serum albumin, or of other serum proteins, may be interesting for clinical purposes because the turnover rates may be changed as one of the consequences of renal, hepatic or gastro-intestinal diseases. Until now, is was not possible to use turnover methods routinely in the clinic, because daily sampling is too tedious for patients and hospital employees. A simplified method of sampling was introduced. This method was then evaluated in order to determine whether or not the results would be significant enough for clinical purposes. 1 tab

    Full Text Available Abstract Background Studies in bipolar disorder (BD to date are limited in their ability to provide a whole-disease perspective - their scope has generally been confined to a single disease phase and/or a specific treatment. Moreover, most clinical trials have focused on the manic phase of disease, and not on depression, which is associated with the greatest disease burden. There are few longitudinal studies covering both types of patients with BD (I and II and the whole course of the disease, regardless of patients' symptomatology. Therefore, the Wide AmbispectiVE study of the clinical management and burden of Bipolar Disorder (WAVE-bd (NCT01062607 aims to provide reliable information on the management of patients with BD in daily clinical practice. It also seeks to determine factors influencing clinical outcomes and resource use in relation to the management of BD. Methods WAVE-bd is a multinational, multicentre, non-interventional, longitudinal study. Approximately 3000 patients diagnosed with BD type I or II with at least one mood event in the preceding 12 months were recruited at centres in Austria, Belgium, Brazil, France, Germany, Portugal, Romania, Turkey, Ukraine and Venezuela. Site selection methodology aimed to provide a balanced cross-section of patients cared for by different types of providers of medical aid (e.g. academic hospitals, private practices in each country. Target recruitment percentages were derived either from scientific publications or from expert panels in each participating country. The minimum follow-up period will be 12 months, with a maximum of 27 months, taking into account the retrospective and the prospective parts of the study.

  4. Pediatric Hodgkin disease in North Tunisia: Clinical and therapeutic study

    International Nuclear Information System (INIS)

    Purpose. - To assess the epidemiological, clinical and therapeutic aspects of pediatric Hodgkin disease (HD) and to study prognosis factors. Patients and methods. - We retrospectively reviewed the medical records of children (≤ 18 years) with HD treated between 1 January 1994 and 31 December 2004. Chemotherapy was undertaken in different departments of hematology and oncology in the North of the country and radiotherapy was centralized at the Salah-Azaiz National Cancer Institute. Results. - One hundred fourteen consecutively treated patients were collected. Median age was 12 years (4-18 years) and sex-ratio was 2.25. Peripheral lymphadenopathy was the predominant circumstance of HD detection (82.5%). The predominant histologic type was nodular sclerosing (56%). Treatment included chemotherapy and involved-field radiotherapy. With a mean follow-up of 23.5 months, relapse rate was 12.2%. Five-year overall survival (OS) and event-free survival (EFS) rates were 95% and 76%, respectively. Five-year OS was 98.2% and 90.8% for early and advanced stages respectively. In multivariate analysis, stage IV (P = 0.029) and early response to initial treatment (P 0.003) retained statistical significance for EFS whereas the only prognostic factor for OS was stage IV (P = 0.002). The long-term side effects were rare. No secondary tumor was noted. Conclusion. - Combined-modality therapy using chemotherapy and involved-field radiotherapy was effective and well-tolerated in early stage pediatric HD. Stage IV patients should be referred to specialized units for intensive treatment. The short median follow-up in our study cannot allow considering long-term effects. (authors)

    Background Borderline gastrointestinal stromal tumors (GISTs) are intermediate tumors between benign and malignant variants; however, the clinical and pathological features of borderline GISTs remain poorly defined. This study aimed to characterize GISTs and to identify a set of borderline criteria for practical use.Methods Medical records and specimens of 840 patients from 12 hospitals were retrospectively examined. Totally 485 and 76 patients with any of the parameters predictive of either malignant or benign tumors were excluded. The Kaplan-Meier method was used to calculate disease-free survival and overall survival rates.Results Among the remaining 279 borderline GIST patients, 223 were followed up for 1 to 31.48 years. Two patients developed local recurrence, and both were cured by subsequent operations alone. The 5-year disease-free survival and overall survival rates were 99% and 100%, respectively. Morphologically, borderline GISTs typically exhibited moderate cellularity, and subsets of them also showed moderate atypia, low mitotic activities, or large tumor size. According to the National Institutes of Health (NIH) consensus criteria, the risk levels of the 279 GISTs were classified to be very low to high. However, the disease-free survival rates were not significantly different among these risk groups (P=0.681).Conclusions The proposed borderline GIST criteria in the current study may complement the existing NIH criteria,based primarily on tumor size and mitotic count, in the evaluation of the biological behaviors of GISTs. Since a subset of borderline GISTs with high risk level showed favorable outcome, the introduction of the borderline GIST system may avoid overdiagnosis and over therapy.

  10. Recent Developments in Instrumentation for Pre-Clinical Imaging Studies

    International Nuclear Information System (INIS)

    Full text: Recent advances in imaging instrumentation have led to a variety of tomograph designs for dedicated pre clinical imaging of laboratory animals. These advances make it possible to image and quantify the kinetics of radiolabelled pharmaceuticals in a wide range of animal models from rodents to non-human primates. Applications include evaluation of promising new radiopharmaceuticals, study of the molecular origins of human disease and evaluation of new forms of therapy. These applications and advances in instrumentation are equally applicable to positron emitters and single photon emitters. This paper provides an overview of recent advances which have led to the current state-of-the-art in pre clinical imaging. The common inorganic scintillators that have been used for SPECT and PET, including some of the promising materials recently studied. The current crystal of choice for SPECT imaging is NaI(Tl) because of its high light output and density which make it well suited to imaging photons in the 100-200 keV range. However, NaI(Tl) has the disadvantage that it must be hermetically sealed to prevent absorption of moisture from the environment. Therefore, investigators have explored a number of alternative inorganic crystals, including CsI(Tl) and cerium-doped yttrium aluminium perovskite (YAP), as well as solid state detectors such as cadmium zinc telluride (CZT). Many of the crystals used in SPECT have also been tried for PET, including NaI(Tl) and YAP. However these crystals have lower stopping power than BGO and NaI(Tl) is also relatively slow. A very promising scintillator for PET is cerium-doped lutetium oxyorthosilicate (LSO) (1) which has similar stopping power to BGO and relatively high light output and fast decay. The first PET scanner to use LSO was the UCLA animal scanner, microPET, which also makes use of a number of other new technologies and unique design features. Recently, improvements in multi-anode and crossed wire position sensitive

    Hemangiosarcoma (HSA) is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be comm...

  12. Fate of clinical research studies after ethical approval--follow-up of study protocols until publication.

    Anette Blümle

    Full Text Available BACKGROUND: Many clinical studies are ultimately not fully published in peer-reviewed journals. Underreporting of clinical research is wasteful and can result in biased estimates of treatment effect or harm, leading to recommendations that are inappropriate or even dangerous. METHODS: We assembled a cohort of clinical studies approved 2000-2002 by the Research Ethics Committee of the University of Freiburg, Germany. Published full articles were searched in electronic databases and investigators contacted. Data on study characteristics were extracted from protocols and corresponding publications. We characterized the cohort, quantified its publication outcome and compared protocols and publications for selected aspects. RESULTS: Of 917 approved studies, 807 were started and 110 were not, either locally or as a whole. Of the started studies, 576 (71% were completed according to protocol, 128 (16% discontinued and 42 (5% are still ongoing; for 61 (8% there was no information about their course. We identified 782 full publications corresponding to 419 of the 807 initiated studies; the publication proportion was 52% (95% CI: 0.48-0.55. Study design was not significantly associated with subsequent publication. Multicentre status, international collaboration, large sample size and commercial or non-commercial funding were positively associated with subsequent publication. Commercial funding was mentioned in 203 (48% protocols and in 205 (49% of the publications. In most published studies (339; 81% this information corresponded between protocol and publication. Most studies were published in English (367; 88%; some in German (25; 6% or both languages (27; 6%. The local investigators were listed as (co-authors in the publications corresponding to 259 (62% studies. CONCLUSION: Half of the clinical research conducted at a large German university medical centre remains unpublished; future research is built on an incomplete database. Research resources are

  13. Clinical studies of chronic pulmonary emphysema on computed tomography

    International Nuclear Information System (INIS)

    In order to assess the usefulness of CT for the evaluation of chronic pulmonary emphysema (CPE), three studies were made as follows. Correlation between CT findings and pulmonary function tests (PFT's) was studied by a scoring method in 41 patients with clinically diagnosed CPE. CT visual score was best correlated with DLCO (r=-0.68) and %DLCO (r=-0.74). The coexistence of bronchial lesion was considered to be responsible for the discrepancy between CT findings and PFT's in patients with low visual score. Alteration ratios of lung field CT numbers in different respiratory phases were studied in 30 cases with CPE, 15 cases with s/o CPE, 7 cases with bronchial asthma and 20 cases with normal lung. Among three parameters we employed, %(I-E)/W, i.e., the alteration ratio of whole lung fields CT numbers between fully inspired and entirely expired state, was proved to be best parameter to separate the disease groups from each other. %(I-E)/W had good correlation with FEV1.0% (r=0.79), V25/H (r=0.80) and RV/TLC (r=-0.75), and this parameter was considered to be useful for the diagnosis of CPE. CT-functional images (CT-FI's) were created from Xe-dynamic CT data of 10 patients with CPE and 6 volunteers with normal lung. For each case, the distribution of ventilation dynamics was compared between outer and inner zone of lung fields. In CT-FI's of normal lungs, the values of washin and washout parameter of outer zone were larger than those of inner zone. In CT-FL's of CPE, the values of washin parameter of inner zone were larger than those of outer zone and the values of washout parameter of outer zone were larger than those of inner zone. CT-FI proved to be helpful in evaluating the distribution of ventilation dynamics in axial planes of the lung with CPE. (author) 83 refs

    Full Text Available INTRODUCTION Benign Lesions of Larynx (BLL have been defined as “An abnormal mass of tissue in larynx, the growth of which exceeds and is coordinated with that of normal tissue and persists in the same excessive manner after cessation of stimuli which evoked the change.” These lesions have significant influence on vocal, social and emotional adjustments of patients. These patients present with hoarseness of voice. AIM A clinical study was undertaken at Govt. ENT Hospital, Hyderabad, for 1 year from January 2014 to December 2014. Aim of this study was to analyze age and sex distribution, symptomatology, sites of involvement, management and recurrence of benign lesions of larynx. MATERIAL AND METHODS A total of 50 patients were studied who were admitted in the hospital. Inclusion criteria: Patients with Hoarseness of Voice (HOV /change of voice, difficulty in breathing and swallowing, vocal fatigue, Foreign Body (FB sensation in the throat. Exclusion criteria: Malignancy of larynx and acute inflammatory conditions of larynx. RESULTS Benign lesions of larynx show male preponderance with M:F ratio of 2.12:1, with common age group between 31 to 40 years. Chronic vocal misuse was the predominant cause and more in professional voice users. The common lesion was Vocal Cord (VC polyp, followed by VC nodules and papillomas. Common side involved was right side. Majority of the patients had to undergo surgery. Majority of recurrence was seen in laryngeal papillomas (33.33%. CONCLUSION Benign lesions of larynx produce symptoms which vary from mild HOV to life threatening stridor. Early diagnosis leads to effective management. Males were more affected and maximum cases seen between 31 to 40 years. Chronic voice abuse, smoking, alcohol, frequent throat clearing and Laryngopharyngeal Reflux (LPR/Gastroesophageal Reflux Disease (GERD are precipitating factors. Microlaryngeal Surgery (MLS, voice rest and speech therapy offer a cost effective, useful and safe

    There is increasing evidence from human and experimental studies that the most important factor governing the outcome in head injury is the severity of diffuse axonal injuries. The authors have experienced 18 cases of severe diffuse axonal injury which showed post-traumatic coma for more than 24 hours and CT findings resembling those of shearing injuries of the cerebral white matter such as have been presented by Zimmerman et al. (1978). The consciousness levels on admission were 6 or less on the Glasgow Coma Scale and all cases were shown clinically to have primary brain stem injury. The main type of head trauma resulted from road traffic accidents (83%). Skull fractures were found in only 5 cases (28%). These findings suggested that acceleration/deceleration injury produce in the patients severe diffuse axonal injury. Initial ICP was below 20 mmHg in 11 cases out of 13 (85%). Parenchymal small hemorrhagic lesions of initial CT were basal ganglia (7 cases), corpus callosum (4 cases), pons (4 cases), midbrain (3 cases) and thalamus (2 cases). Extraparenchymal hemorrhagic lesions included intraventricular hemorrhage (6 cases) and subarachnoid hemorrhage (6 cases). Two autopsied cases of severe diffuse axonal injury (acute case and chronic case) showed remarkable congestion and edema in the deep part of the frontal white matter. Microscopic examination revealed marked axonal degeneration including axonal retraction ball in the corpus callosum, in the internal capsule and in the white matter of the brain stem. Glasgow Outcome Scale of the 18 patients at 3 months after the trauma made us concerned that no patients indicated good recovery or even only moderate disability.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2770962

    A clinical and radiological study was done on 96 cases of spontaneous pneumothorax, encountered in the Dept. of Radiology, Busan National University Hospital during last 3 years from March 1979 to March 1982. The result were summarized as follows: 1. In the age distribution, the ages between 20 and 39 years were most highest, as 54 cases (56.3%). In the sex distribution, the ratio of male to female was 5 : 1 in male predominance. 2. The underlying pathology of the total 96 cases of spontaneous pneumothorax were of tuberculous origin in 33.3 % and non-tuberculous origin in 66.7%. And below 20 years, most were of non- tuberculous origin. 3. In the cases of lung collapse over 2/3, non-tuberculous origin was more than tuberculous origin and had characteristics of significant mediastinal shifting, in contrast to lower percentage of fluid level by chest radiography. 4. The rupture of biebs or bullae was the main immediate causes of spontaneous pneumothorax, independent of the underlying pathology. 5. In only 27 cases (28.1%) among total 96 cases, bullae or biebs could be detected on the chest radiography. 6. In treatment of spontaneous pneumothorax, the closed thoracotomy with under water seal drainage is accepted to be the general method of treatment. But open thoracotomy is considered as the best useful therapeutic procedure to prevent the recurrence, whenever bullae or blebs are found on the chest radiography. 7. In the cases of closed thoracotomy, the recurrent rate was 25.0% and most cases were found at the ipsilateral side of the first attack. 8. Within a week, the collapsed lung were well expanded in most cases of total 96 cases, after closed thoracotomy.

    International Nuclear Information System (INIS)

    A clinical and radiological study was done on 96 cases of spontaneous pneumothorax, encountered in the Dept. of Radiology, Busan National University Hospital during last 3 years from March 1979 to March 1982. The result were summarized as follows: 1. In the age distribution, the ages between 20 and 39 years were most highest, as 54 cases (56.3%). In the sex distribution, the ratio of male to female was 5 : 1 in male predominance. 2. The underlying pathology of the total 96 cases of spontaneous pneumothorax were of tuberculous origin in 33.3 % and non-tuberculous origin in 66.7%. And below 20 years, most were of non- tuberculous origin. 3. In the cases of lung collapse over 2/3, non-tuberculous origin was more than tuberculous origin and had characteristics of significant mediastinal shifting, in contrast to lower percentage of fluid level by chest radiography. 4. The rupture of biebs or bullae was the main immediate causes of spontaneous pneumothorax, independent of the underlying pathology. 5. In only 27 cases (28.1%) among total 96 cases, bullae or biebs could be detected on the chest radiography. 6. In treatment of spontaneous pneumothorax, the closed thoracotomy with under water seal drainage is accepted to be the general method of treatment. But open thoracotomy is considered as the best useful therapeutic procedure to prevent the recurrence, whenever bullae or blebs are found on the chest radiography. 7.

    Full Text Available Background and Design: The definition of emergent diseases includes potentially risky diseases that need urgent medical intervention. Diagnostic and therapeutic processes are managed mostly at ourpatient setting in dermatology. Therefore, it is unclear that which diseases are real emergencies and which patients apply urgently. There are a few studies assessing this topic. Our aim was to evaluate patients referred to our clinic urgently, and to review the concept of ‘‘real dermatologic emergency’’ by comparing dermatologic emergency patients and outpatients. Material and Method: A total of 800 patients (400 urgent patients, 400 outpatients were included. Demographic features, complaints, disease duration and severity, whether the disease occurs for the first time were questionned, application time and diagnosis were recorded. The opinions of patients and physicians were inquired about why they thought that the disease was emergent. Results: Most common skin diseases were acute urticaria-angioedema, contact dermatitis, and insect bite in emergency patients; acne vulgaris, verruca and tinea pedis in outpatients. Itching was more common in emergency patients. Emergency patients' complaints were more severe than those of outpatients. Patients who experience disease first time applied to emergency service more than others. Emergency patients had a shorter disease duration than outpatients. Patients and physicians revealed different reasons and criteria about the urgency of the diseases. 93.5% of patients and 49% of physicians thought that existing disease was emergent. Conclusion: Our data reveal that the concept of dermatologic emergency is unsettled. It changes according to socio-cultural, personal features and to the present health system. Determination of the main criteria of the definition of “dermatologic urgent”, and training of dermatologists, emergency centers’physicians and also of patients in this regard seem to be a necessity

  19. An experimental and clinical study on the dissecting aortic aneurysm

    International Nuclear Information System (INIS)

    In the treatment of dissecting aortic aneurysm, it is important to understand the exact conditions of the disease. For this purpose Aortography (AOG) and X-ray computorized tomography (CT) have been used. Magnetic Resonance Imaging (MRI) and the ultrasonic pulsed Doppler duplex system are completely non-invasive and may be used instead of AOG and CT. Experimental aortic dissection was done surgically using modified Blanton's method in 8 mongrel dogs. MRI and the ultrasonic pulsed Doppler duplex system were used on these dogs before and after surgery which consisted of surgical closure of entry and insertion of Ivalon Sponge to false lumen. MRI patterns were classified into three: i.e, low, middle, and high intensity. The ultrasonic pulsed Doppler duplex system patterns were classified into four: i.e, normal flow, to and fro, turbulent flow and wall motion patterns respectively. These patterns of MRI and the ultrasonic pulsed Doppler duplex system were closely correlated to autopsy findings. These results indicated that MRI and the ultrasonic pulsed Doppler duplex system are useful to evaluate the changes of figures and hemodynamics of the false lumen. In the clinical study, MRI was performed on 26 patients of dissecting aortic aneurysm before and after surgery. These results were compared with those of AOG and CT. In the detection of the intimal flap, the main arterial branches, and the location of the entry and reentry, MRI was superior to CT and almost equal to AOG. key words: dissecting aortic aneurysm, hemodynamics of aortic dissection, the Ivalon Sponge Occlusion method, MRI, the ultrasonic pulsed Doppler duplex system.

    The objective of this study was to determine the relationship between nerve conduction velocity (NCV) and hyperglycemia and to assess the extent of NCV changes in adult-onset diabetic patients before and after diabetic treatment. Twenty-five diabetic males (mean age = 50.9 years) were tested twice prior to beginning diabetic treatment. Eighteen of these 25 were also tested at 1, 3, 6, and 12 months after initiation of therapy. Both groups were compared to 23 age-matched controls. Each test session consisted of NCV and clinical sensory and blood chemistry testing. The findings revealed that, before treatment average NCVs of the median, peroneal sural, and tibial nerves and H-reflex latency results were all significantly impaired in diabetic subjects (p less than 0.025). No difference was found between right and left NCVs of the same nerve (p less than 0.05) and NCVs in the lower as well as the upper extremities were significantly reduced (p less than 0.05). Thus, it appears that the neuropathy in these patients was symmetrical and diffuse. Peroneal and median motor nerves showed the greatest amount of NCV slowing when compared to normal values. Furthermore, median, peroneal, and tibial motor NCVs and H-reflex latencies correlated significantly with the degree of hyperglycemia in diabetic subjects before treatment. After initiation of diabetic treatment, median motor NCVs after 1, 3, 6 and 12 months showed significantly improvement when compared to baseline NCV values (all p less than 0.05). Also, the improvement in median NCVs after 3 and 13 months and peroneal NCV after 3 months directly correlated to decreased fasting plasma glucose levels (p less than 0.05). PMID:7092528

    1981-07-01

    Eighty-four children with steroid-responsive nephrotic syndrome who had been shown to have, or were believed to have, minimal change histology were investigated to study the relationship between steroid-responsive nephrotic syndrome and allergy. They were found to have a greater incidence of the standard atopic disorders--asthma, eczema, recurrent urticaria, and hay fever. Their 1st-degree relatives had an increased incidence of these atopic disorders too. A nasal discharge was a frequent precursor or an accompaniment of nephrotic syndrome, but an overt atrophic disorder at the same time was rare. Such disorders, related to relapse, occurred in only 5 children; in none was it a consistent or recurrent happening at the time of each relapse. No example of pollen hypersensitivity nephrotic syndrome was found, and no particular allergen could be identified with certainty as responsible for a child's nephrotic syndrome. No association was found between the time of relapse and the season of the year, or the season in which the child was born. Children with nephrotic syndrome had a greater incidence of positive skin tests to common antigens, the comparative frequency of positive reactions to different antigens being similar to that found in children with asthma, although the total frequency was about half that of children with asthma. Despite the increased incidence of clinical features of atopy, measures to reduce the frequency of relapse of nephrotic syndrome by allergen avoidance, the use of sodium cromoglycate, and the use of a new oral antiallergic drug were unsuccessful.

    In this study we reviewed the clinical features, diagnoses and treatments of 232 cases of nasal bone fracture cases treated at our department from January 1994 to June 2000. A marked predominance of males in the age range of 10-29 years was noted. Analysis of the causes of the nasal fractures were attributed to fighting (66 cases), traffic accidents (64 cases), sports (56 cases) and others (46 cases). The external appearance of nasal fractures were divided into 5 types, 85 cases of the displacement type, 27 cases of the depressed type, 32 of the mixed type, 56 of the non-deformation type and 32 of the unclassified type because of facial swelling. The sensitivity of conventional X-ray examination in identifying nasal fractures was 75.6%. Computed tomography scan (CT scan) was performed in 196 patients and showed that the middle and lower portions of nasal bones were fractured more easily than those of the upper portion. Nasal septum fracture occurred in 22 cases (11.2%). Other facial fractures combined with nasal fracture were found in 40 cases (20.4%). The type of combined fracture depended on the cause of the injury, for example, the combination of nasal and blow-out fracture was often caused by fighting, and many combined fractures of more than two facial bones resulted from traffic accidents. A total of 83 patients (35.8%) received reduction of the nasal bone fractures under general anaesthesia. The measurement of irradiation of each radiological examination revealed that the exposed dose of the newest model CT was similar to that of the conventional X-ray examination and tomography.

  3. Hamartomatous polyps - a clinical and molecular genetic study.

    Jelsig, Anne Marie

    2016-08-01

    Hamartomatous polyps (HPs) in the gastrointestinal (GI) tract are rare compared to other types of GI polyps, yet they are the most common type of polyp in children. The symptoms are usually rectal bleeding, abdominal pain, obstipation, anaemia, and/or small bowel obstruction. The polyps are typically removed concurrently with endoscopy when located in the colon, rectum, or stomach, whereas polyps in the small bowel are removed during push-enteroscopy, device-assisted enteroscopy, or by surgery. HPs can be classified as juvenile polyps or Peutz-Jeghers polyps based on their histopathological appearance. Patients with one or a few juvenile polyps are usually not offered clinical follow-up as the polyp(s) are considered not to harbour any malignant potential. Nevertheless, it is important to note that juvenile polyps and HPs are also found in patients with hereditary hamartomatous polyposis syndromes (HPS). Patients with HPS have an increased risk of cancer, recurrences of polyps, and extraintestinal complications. The syndromes are important to diagnose, as patients should be offered surveillance from childhood or early adolescence. The syndromes include juvenile polyposis syndrome, Peutz-Jeghers syndrome, and the PTEN hamartoma tumour syndrome. Currently, the HPS diagnoses are based on clinical criteria and are often assisted with genetic testing as candidate genes have been described for each syndrome. This thesis is based on six scientific papers. The overall aim of the studies was to expand the knowledge on clinical course and molecular genetics in patients with HPs and HPS, and to investigate research participants' attitude towards the results of extensive genetic testing.   Paper I: In the first paper we investigated the occurrence, anatomic distribution, and other demographics of juvenile polyps in the colon and rectum in Denmark in 1995-2014. Based on the Danish Pathology Data Bank we found that 1772 patients had 2108 JPs examined in the period, and we

    Objective Evolutionary stroke is one common and important subgroup of acute ischemic stroke with nerve damage symptoms evolutionarily heaving. There is not effective methods clinically to stop its development. This article aims to study the feasibility and effectiveness of Defibrase therapy on evolutionary stroke through observing curative effect of evolutionary stroke treated by defibrase therapy and analyze and compare with that of treated by routine medicine. Methods Select 52 evolutionary stroke cases 8 hours to 5 days after stroke and divide them into treatment group(28 cases):treated by 250ml saline intravenous transfusion with 10u Defibrase,once per day,after 3 successive days switch to routine treatmcnt, and control group(24 cases):receive routine treatment. Both groups have not found significant difference in age and severity through X2 inspection,and are comparable both in case history and complication accumulation.The curative effect is evaluated 10 days and 20 days after treatment respectively.Results 10 days after treatment, in treatment group total efficiency is 63%,in control group that is 36%;20 days after treatment,in treatment group total efficiency is 82% and that in control group is 53%.Both have significant difference(P<0.01).No untoward effect such as hemorrhage occurs to both groups.Discussion and Conclutions In general speaking.within 6 hours after ischmic stroke is the optimum time to conduct thrombus-dissolution,but for evolutionary stroke the situation is still developing within several hours and even several days after stroke,that is to say thrombus is still developing or ischemia half dark band is changing to irreversible .Therefore evolutionary stroke itself is the indication of needing thrombus dissolution.Volume urokinase thrombus-dissolving therapy is easy to superven serious complication such as intracrainial hemorrhage. Insertion treatment is not matured enough limited to equipment,infarct position and curative effect. Defibrase

    2015-09-01

    Full Text Available Hemangiosarcoma (HSA is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be communicated to those responsible for the pets, so that, with all available information, they can make a free and informed choice about the treatment they want for their pet, considering the financial commitment, survival time and quality of life associated with chemotherapy. This article describes the clinical case of a female greyhound dog of eight years of age that was brought to consultation for a skin tumor on the right hind limb in the distal tibia. She was diagnosed with noninvasive cutaneous HSA through histopathology, reason why the owners chose not to do the chemotherapy; however, 10 months later she presented recurrent skin lesions and a popliteal lymph node corresponding to hemangiosarcoma and hemangioma respectively, and three weeks later the patient developed cardiac tamponade due to a cardiac mass with associated spill, which resulted in her euthanasia.

This type of leadership allows us to reframe both the care-giving and organizational roles of nurses and other front-line clinical staff. Little research has been done to explore what leadership means at the point of care, particularly in reference to the relationship between health care practitioners and patients and their family caregivers. The Adaptive Leadership framework, based on complexity science theory, provides a useful lens to explore practitioners' leadership behaviors at the point of care. This framework proposes that there are two broad categories of challenges that patients face: technical and adaptive. Whereas technical challenges are addressed with technical solutions that are delivered by practitioners, adaptive challenges require the patient (or family member to adjust to a new situation and to do the work of adapting, learning, and behavior change. Adaptive leadership is the work that practitioners do to mobilize and support patients to do the adaptive work. The purpose of this paper is to describe this framework and demonstrate its application to nursing research. We demonstrate the framework's utility with five exemplars of nursing research problems that range from the individual to the system levels. The framework has the potential to guide researchers to ask new questions and to gain new insights into how practitioners interact with

    A total of 5726 blood specimens (from children aged 14 years and younger) were studied for the serological evidence of brucellosis. Ninety-three (1.6 per cent) showed diagnostic agglutinin titres with a geometric mean titre of 403 (SD +/- 547). Forty-three (59.7 per cent) blood specimens yielded the growth of Brucella melitensis. Thirty-nine patients (41.93 per cent) were shepherds, who constituted the major occupational group affected in the present series. More than 60 per cent of the patients had a history of both consumption of fresh goat's milk and close animal contact. The habit of consuming fresh goat's milk to obtain relief from chronic ailments was noted in nine patients. Seventy-three (78.49 per cent) were males and 20 (21.51 per cent) were females, with a male to female ratio of 3:1. The disease occurred mainly in the school age group (mean age 10.3 years). All the patients had an acute history of less than 2 months. Forty-nine (52.68 per cent) patients presented with persistent fever, 19 (20.43 per cent) with joint pain, and the rest with a combination of fever and joint pain with and without low backache, fever being the commonest complaint. One case presented with involuntary movements of limbs alone and the other with burning feet only. Pityriasis alba was the consistent physical finding, with fever in the majority of the patients. The major joint found to be involved was the knee (52.77 per cent). The synovial fluid obtained from the knee joint of five patients demonstrated Brucella agglutinins and also three grew B. melitensis. Eight patients presented with complications that included skin lesions (3), carditis (2), neurobrucellosis such as chorea (1), peripheral neuritis (1), and meningitis (1). Brucella melitensis biotype 1 was successfully isolated from the papular eruption of one out of three cases who presented with skin lesions. To our knowledge this is the fourth confirmed isolation of B. melitensis from skin lesions with brucellosis

    During a 10-year period ending in 1985, we observed atrophy of the maculopapillary bundle in both eyes of 25 cases examined post mortem. We retrospectively examined the clinical history and general autopsy findings for evidence of malnutrition. An adequate clinical history was obtained in 24 patients, and an autopsy was performed on 21 patients. Our review disclosed that all 25 patients had marked nutritional deprivation, most commonly from alcohol abuse (20 patients), advanced carcinoma (8 patients, 7 of whom were also alcohol abusers), and other malnutritional and disabling conditions (4 patients). A history of heavy smoking was documented in 11 patients. Our findings support the contention that dietary deficiency plays a role in the pathogenesis of the condition that in the past has been referred to as tobacco-alcohol amblyopia and more recently has been called nutritional amblyopia.

    Full Text Available Recently, David Barlow (2004, a pioneer in the field of anxiety disorders, has proposed that psychologists should abandon the concept of psychotherapy and rather use the one of “psychological treatment”. The provoking idea behind this proposal is that the concept of psychotherapy, relying on the notion of “therapeutic school” should be discarded by professional psychologists because it relies too much on conceptions based on pre-scientific models. Barlow (2004 insists that, today, psychology as an empirical science has gathered sufficient knowledge and know-how to found clinical practice. It is no longer necessary to rely on pre-scientific theories. Further, Barlow’s perspective opens clinical practice to the entire field of psychology, i.e. to the advances accomplished by research on emotion, cognition, learning, development, etc.

    Full Text Available Background: In order to improve the clinical treatment level of urinary system injury, it is necessary to build up an animal model of urinary system wound, which is not only analogous to real clinical practice, but also simple and practical. Methods: We have developed the third generation of firearm fragment wound generator based on the first and the second producer. The best explosive charge of the blank cartridge was selected by gradient powder loading experiments. The firearm fragment injuries were made to the bulbous urethra of 10 New Zealand male rabbits. One week preoperatively and 2, 4 and 8 weeks postoperatively, all the animals underwent urethroscopy and urethrography. At 2, 4 and 8 weeks postoperatively, two animals were randomly selected and killed, and the urethra was cut off for pathological examination. Results: The shooting distance of the third generation of firearm fragment wound generator is 2 cm. The best explosive charge of the blank cartridge is 1 g of nitrocotton. All rabbits survived the procedures and stayed alive until they were killed. Injuries were limited to bulbous urethra and distal urethra. Round damaged areas, 1-1.5 cm in length, on the ventral wall were observed. Ureteroscopy results showed that canal diameter gradually shrank by over 50% in 9 rabbits. The rate of success was 90%. Urethrography result noted that a 1-1.3 cm stricture was formed at the bulbous urethra. Histology results of injured stricture urethra showed that fibrous connective tissue hyperplasia and hyaline degeneration caused further stricture in the canal. Conclusions: The third generation of firearm fragment wound generator imitates the bullet firing process and is more accurate and repeatable. The corresponding rabbit model of traumatic complex urethral stricture simulates the real complex clinical conditions. This animal model provides a standardized platform for clinical researches on treating traumatic injuries to the urinary system.

    Objective:To classify and characterize spider bites among inquiries to the National Poison Information Center (NPIC) between1995 and2004, in terms of the epidemiology and clinical symptomatology.Methods: Clinical and epidemiological data were obtained from theNPIC’s patient records. The following information was recorded for each spider bite: demographics, circumstances of the bite, and local and systemic effects.Results: A total of82 cases were reported. The accidents were mostly seen during August. The gender distribution was59.76%male, 37.20% female, and2.44% unknown and the20-29 age group presented more spider bites. Most of the cases were in the Central Anatolia, Marmara, Mediterranean, and Black Sea regions. Local symptoms were observed in60.87% of the cases, including local pain, edema, redness, itching, debris, burning, and numbness. Systemic symptoms were observed such as nausea, vomiting, abdominal pain, lethargy, anxiety, weakness, somnolence, dyspnea, hypertension, hypotension, and hyperthermia.Conclusions: In conclusion, these findings emphasize the presence of medically important spider species in Turkey. All patients and especially pediatric patients should be admitted to the hospital. Identification of spider species may be considered a useful clinical and epidemiological tool in determining the incidence and risk of spider bites.

  7. Clinical studies on cerebral blood flow in chronic subdural hematoma

    International Nuclear Information System (INIS)

    Cerebral blood flow (CBF) and clinical symptoms were examined between pre- and post-operations in twenty-four patients with unilateral chronic subdural hematoma. The following results were obtained by intravenous 133Xe method : 1. There was a reducing tendency of the CBF (hemisphere) on hematoma side, in most cases. While, the groups of headache and disturbances of consciousness did not give a laterality between hematoma and opposite side without the group of hemiparesis. 2. The absolute values of the CBF in the groups of headache and disturbances of consciousness were correlated with the clinical symptoms. In the group of hemiparesis, the laterality between hematoma and opposite side was correlated with the clinical symptoms. 3. In the group of hemiparesis, the F-flow (fast-flow) had sensitive reaction more than the ISI (initial slope index) with symptomatic improvement. 4. It was found that there was not an increase in the absolute value of the CBF, which was under the normal limit between pre- and post-operations in the case without improvement. By SPECT (Method of IMP), the following results were obtained : 1. There was the area of defect at the location of hematoma and the CBF tended to reduce at the subcortical white matter and at the basal ganglia of hematoma side. 2. The CBF of the contralateral hematoma side in the hemisphere of cerebellum was also tended to reduce. (author)

    1,25-Dihydroxycholecalciferol (calcitriol) is recognized widely for its effects on bone and mineral metabolism. Epidemiological data suggest that low Vitamin D levels may play a role in the genesis of prostate cancer and perhaps other tumors. Calcitriol is a potent anti-proliferative agent in a wide variety of malignant cell types. In prostate, breast, colorectal, head/neck and lung cancer as well as lymphoma, leukemia and myeloma model systems calcitriol has significant anti-tumor activity in vitro and in vivo. Calcitriol effects are associated with an increase in G0/G1 arrest, induction of apoptosis and differentiation, modulation of expression of growth factor receptors. Glucocorticoids potentiate the anti-tumor effect of calcitriol and decrease calcitriol-induced hypercalcemia. Calcitriol potentiates the antitumor effects of many cytotoxic agents and inhibits motility and invasiveness of tumor cells and formation of new blood vessels. Phase I and II trials of calcitriol either alone or in combination with carboplatin, taxanes or dexamethasone have been initiated in patients with androgen dependent and independent prostate cancer and advanced cancer. Data indicate that high-dose calcitriol is feasible on an intermittent schedule, no dose-limiting toxicity has been encountered and optimal dose and schedule are being delineated. Clinical responses have been seen with the combination of high dose calcitriol+dexamethasone in androgen independent prostate cancer (AIPC) and apparent potentiation of the antitumor effects of docetaxel have been seen in AIPC. These results demonstrate that high intermittent doses of calcitriol can be administered to patients without toxicity, that the MTD is yet to be determined and that calcitriol has potential as an anti-cancer agent.

    Objective To explore the characteristics of arrhythmogenic rightventricular cardiomyopathy (ARVC). Methods Seven patients with arrhythmogenic right ventricular cardiomyopathy and 34 members of three families were studied. All patients and family members underwent history collection, clinical examination, electrocardiogram (ECG), two-dimensional echocardiography (2-DE) and a signal averaging electrocardiogram. Programmed ventricular stimulation was performed in five patients. Results All patients and family members had normal morphologic characteristics and normal function of the left ventricular by 2-DE. Fourteen persons had abnormal findings indicating ARVC. Five had enlargement of the right ventricular with diffused hypocontractility, eight had thin and systolic bulging in the focal anterior wall with hypokinesia and one had bulging of the inferior wall. Twenty-five persons (seven patients and 18 family members) had abnormal findings in ECG. Positive ventricular late potential was recorded in 13 persons (six patients). Two to three monomorphic ventricular tachycardia (VT) with left bundle branch block (LBBB) configurations were induced in five patients. Ventricular fibrillation was induced in two patients during the electrophysiologic study (EPS). Five patients had very high pacing threshold and/or ineffective pacing in one or many regions of the right ventricle. Two members of one family died suddenly. One member was a dwarf with ARVC. Spontaneous VT with a left bundle branch block (LBBB) configuration was recorded in five patients, polymorphic VT with extremely short coupling interval in one, and premature ventricular complexes with LBBB configuration in 12 (six patients). Conclusion Our familial study strongly suggests that ARVC may be a hereditary disease and it is helpful in the diagnosis and detection of ARVC. The most common manifestations were abnormal structure and function of the right ventricle and abnormal ECG of repolarization and ventricular

  1. Clinical study of aplastic anemia among A-bomb survivors

    International Nuclear Information System (INIS)

    In 90 patients with aplastic anemia who were seen at Dept. Med. RINMB, Hiroshima Univ. from 1962 to March, 1980, clinical findings of 33 A-bomb survivors (which included the second generation of the survivors) and those of 57 nonexposed patients were compared. No relationship was found between the age at the time of exposure and the period preceding onset of the disease. The A-bomb survivors showed higher neutrophil counts and higher reticulocyte counts than the nonexposed patients. There were less severe cases in the A-bomb survivors. There was no difference in the incidence of atypical aplastic anemia between the exposed patients and the nonexposed ones. No difference was found in overall survival (one-year and five-year survival rates) between the exposed and the nonexposed. The A-bomb survivors often had complete remission or maintenance of remission, and rarely had acute progression. These results suggested that clinical picture of aplastic anemia in the A-bomb survivors is different from that in the nonexposed patients. (Ueda, J.)

    Full Text Available Abstract Background Patient encounters are the core learning activity of Australian general practice (family practice training. Exposure to patient demographics and presentations may vary from one general practice registrar (vocational trainee to another. This can affect comprehensiveness of training. Currently, there is no mechanism to systematically capture the content of GP registrar consultations. The aim of the Registrar Clinical Encounters in Training (ReCEnT study is to document longitudinally the nature and associations of consultation-based clinical and educational experiences of general practice registrars. Methods/design This is an ongoing prospective multi-site cohort study of general practice registrars’ consultations, entailing paper-based recording of consultation data. The study setting is general practices affiliated with three geographically-based Australian general practice regional training providers. Registrars record details of 60 consecutive consultations. Data collected includes registrar demographics, details of the consultation, patient demographics, reasons for encounter and problems managed. Problems managed are coded with the International Classification of Primary Care (second edition classification system. Additionally, registrars record educational factors related to the encounter. The study will follow the clinical exposure of each registrar six-monthly over the 18 months to two years (full-time equivalent of their general practice training program. Conclusions The study will provide data on a range of factors (patient, registrar and consultation factors. This data will be used to inform a range of educational decisions as well as being used to answer educational research questions. We plan to use ReCEnT as a formative assessment tool for registrars and help identify and address educational needs. The study will facilitate program evaluation by the participating training providers and thus improve articulation

    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

    Premature ejaculation (PE) is a most common sexual dysfunction, for which dapoxetine, a novel selective serotonin (5-HT) re-uptake inhibitor (SSRI), is the only licensed oral medicine at present. With the advantages of fast absorption, rapid action, on-demand medication, and short half-life time, dapoxetine has been proved by clinical trials to be effective in prolonging the intravaginal ejaculation latency time (IELT) and improving the overall condition of PE patients in various areas and populations. Compared with the traditional SSRIs, dapoxetine has a better safety and tolerability. The most frequently reported dapoxetine-related adverse events include nausea, diarrhea, headache and dizziness, but with very few severe or serious cases. PMID:26665685

    Full Text Available Acute normovolaemic haemodilution (ANH is a technique used to preserve a patient's owns red blood cells and reduce the incidence of heterogeneous blood transfusion. This paper describes the use of the technique in a dog and a kitten. A significant benefit of ANH can be shown in the canine case presented. The dog lost 1800m of blood during surgery but the haematocrit was only reduced to 33% 6 hours after the end of surgery. The kitten, however, did not benefit from ANH. It lost a small volume of blood during surgery and developed complications. This paper also describes some of the potential complications that may occur. To the best of my knowledge, this is the 1st clinical description of ANH in a dog and a cat.

    Biofield therapies are noninvasive therapies in which the practitioner explicitly works with a client's biofield (interacting fields of energy and information that surround living systems) to stimulate healing responses in patients. While the practice of biofield therapies has existed in Eastern and Western cultures for thousands of years, empirical research on the effectiveness of biofield therapies is still relatively nascent. In this article, we provide a summary of the state of the evidence for biofield therapies for a number of different clinical conditions. We note specific methodological issues for research in biofield therapies that need to be addressed (including practitioner-based, outcomes-based, and research design considerations), as well as provide a list of suggested next steps for biofield researchers to consider.

    A series of 13 cases of feline membranous nephropathy is presented. Two groups were distinguished clinically; eight cats had the nephrotic syndrome and five others were in renal failure but not nephrotic. The definitive diagnosis was based on histological, immunofluorescence and ultrastructural examinations of renal tissue obtained at renal biopsy or necropsy. Glomerular lesions were classified according to the degree of glomerular change into three distinct groups; mild, moderately severe and advanced. A relationship was established between the mild and moderately severe groups and cats with the nephrotic syndrome, and the advanced group and cats in renal failure. Diuretic therapy was satisfactory in initial control of oedema in the nephrotic cases. Monitoring of previously nephrotic cats for up to three years indicated that the disease is progressive, although in some cases it is sufficiently slow for a cat to live a relatively normal life without continuing treatment. The prognosis for cats presented in renal failure is hopeless. PMID:552741

  14. Clinical study for symptomatic cerebral vasospasm treated by endovascular therapy

    International Nuclear Information System (INIS)

    Objective: To observe the treatment effect for cerebral vasospasm by endovascular therapy. Methods: Five patients with subarachnoid hemorrhage were reported, in which aneurysms had been clipped and super-selective intra-arterial infusion of papaverine (IAP) and percutaneous transluminal angioplasty (PTA) were employed for the treatment of symptomatic cerebral vasospasm. Results: Satisfactory clinical outcome was obtained in 4 patients in which endovascular therapies were used within 2 hours after the onset, whereas moderate deficits remained in 1 patient treated in 10 hours. Conclusion: In patients with aneurysmal subarachnoid hemorrhage in whom conservative therapy including hypertensive, hypervolemic therapy and calcium channel blocker nimodipine has failed, PTA and IAP have become a valuable therapeutic alternative and can get a better effect if used as early as possible

    An adequate amount of bone all around the implant surface is essential in order to obtain long-term success of implant restoration. Several techniques have been described to augment alveolar bone volume in critical clinical situations, including guided bone regeneration, based on the use of barrier membranes to prevent ingrowth of the epithelial and gingival connective tissue cells. To achieve this goal, the use of barriers made of titanium micromesh has been advocated. A total of 13 patients were selected for alveolar ridge reconstruction treatment prior to implant placement. Each patient underwent a tridimensional bone augmentation by means of a Ti-mesh filled with intraoral autogenous bone mixed with deproteinized anorganic bovine bone in a 1:1 ratio. Implants were placed after a healing period of 6 months. Panoramic x-rays were performed after each surgical procedure and during the follow-up recalls. Software was used to measure the mesial and the distal peri-implant bone loss around each implant. The mean peri-implant bone loss was 1.743 mm on the mesial side and 1.913 mm on the distal side, from the top of the implant head to the first visible bone-implant contact, at a mean follow-up of 88 months. The use of Ti-mesh allows the regeneration of sufficient bone volume for ideal implant placement. The clinical advantages related to this technique include the possibility of correcting severe vertical atrophies associated with considerable reductions in width and the lack of major complications if soft-tissue dehiscence and mesh exposures do occur.

    Mechanical ventilation can cause and perpetuate lung injury if alveolar overdistension, cyclic collapse, and reopening of alveolar units occur. The use of low tidal volume and limited airway pressure has improved survival in patients with acute lung injury or acute respiratory distress syndrome. The use of recruitment maneuvers has been proposed as an adjunct to mechanical ventilation to re-expand collapsed lung tissue. Many investigators have studied the benefits of recruitment maneuvers in ...

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

    A gap in information about pediatric clinical trials exists, and parents remain uncertain about what is involved in research studies involving children. We aimed to understand parent perspectives about pediatric clinical research after viewing the online Children and Clinical Studies (CaCS) program. Using a qualitative descriptive study design, we conducted focus groups with parents and phone interviews with physicians. Three themes emerged providing approaches to improve parent's understanding of clinical research by including strategies where parents (a) hear from parents like themselves to learn about pediatric research, (b) receive general clinical research information to complement study-specific details, and (c) are provided more information about the role of healthy child volunteers. Parents found the website a valuable tool that would help them make a decision about what it means to participate in research. This tool can assist parents, providers, and researchers by connecting general information with study-specific information. PMID:26711142

    Purpose: To prospectively compare plans generated with iCycle, an in-house-developed algorithm for fully automated multicriterial intensity modulated radiation therapy (IMRT) beam profile and beam orientation optimization, with plans manually generated by dosimetrists using the clinical treatment planning system. Methods and Materials: For 20 randomly selected head-and-neck cancer patients with various tumor locations (of whom 13 received sequential boost treatments), we offered the treating physician the choice between an automatically generated iCycle plan and a manually optimized plan using standard clinical procedures. Although iCycle used a fixed “wish list” with hard constraints and prioritized objectives, the dosimetrists manually selected the beam configuration and fine tuned the constraints and objectives for each IMRT plan. Dosimetrists were not informed in advance whether a competing iCycle plan was made. The 2 plans were simultaneously presented to the physician, who then selected the plan to be used for treatment. For the patient group, differences in planning target volume coverage and sparing of critical tissues were quantified. Results: In 32 of 33 plan comparisons, the physician selected the iCycle plan for treatment. This highly consistent preference for the automatically generated plans was mainly caused by the improved sparing for the large majority of critical structures. With iCycle, the normal tissue complication probabilities for the parotid and submandibular glands were reduced by 2.4% ± 4.9% (maximum, 18.5%, P=.001) and 6.5% ± 8.3% (maximum, 27%, P=.005), respectively. The reduction in the mean oral cavity dose was 2.8 ± 2.8 Gy (maximum, 8.1 Gy, P=.005). For the swallowing muscles, the esophagus and larynx, the mean dose reduction was 3.3 ± 1.1 Gy (maximum, 9.2 Gy, P<.001). For 15 of the 20 patients, target coverage was also improved. Conclusions: In 97% of cases, automatically generated plans were selected for treatment because of

    1978-06-01

    Full Text Available Endotoxin (lipopolysaccharide, LPS and LPS antibody in the blood were studied in 61 cases of ulcerative colitis (U.C. by radioimmunoassay. Lysozyme (LZM concentration was also studied by the turbidimetric method. As a result, it was found that the blood LPS value as well as serum LZM concentration reflects the clinical observations. The case of endotoxemia in the active phase group showed a positive correlation between the LPS value and LZM concentration. LPS antibody which could not be detected in many cases of the active phase, had a high titer in cases of remission with a long history of the disease. These results would suggest that in U.C. with damaged intestinal mucosal barrier, LPS originating from intestinal flora enters into the blood and aggravates the disease and further that this invading LPS releases LZM into the blood. The same studies were performed on 7 cases of Crohn's disease and the same result was obtained.

    Full Text Available A comparison was made of the clinical findings of 59 patients with liver cirrhosis (LC accompanied with hepatocellular carcinoma (HCC (of which 35 had ascites and 24 did not at the time of admission and 164 patients with LC, but without HCC (of which 39 had ascites and 125 did not. HCC patients were older and more often had hepatomegaly, vascular spider and pleural effusion than LC patients. Ascites was more frequently observed in HCC than in LC patients when the serum albumin level and the indocyanine green disappearance rate were relatively well maintained and when peripheral edema was absent. There was no difference in the ascitic protein concentration between LC and HCC patients. Malignant cells were detected in ascites only in 14% of the HCC patients. These facts indicate the presence of ascites-inducing factors in HCC patients which have no direct relation to serum colloid osmotic pressure and effective hepatic blood flow. Almost all of the HCC patients with ascites (96% died with ascites, whereas 54% of the LC patients with ascites recovered from the ascitic condition.

    The author has clinically and radiologically investigated 57 cases of odontogenic keratocyst in 47 patients consisted of 26 males and 21 females aged from 2 to 63 years, who were pathologically diagnosed as odontogenic keratocyst at infirmaries of dental colleges, Yonsei University and Seoul national university during 1965-1986. The results were as follows: 1. The peak incidence of the disease was on their teenagers (29.8%). The ratio of Male/Female was 1.23 : 1 and incidence rate of males showed higher than their counterpart. 2. The most frequent complains were swelling in (65.9%) followed by pus discharge, unknown mass, pain, residual root. 3. The most common site was mandibular third molar and mandibular ramus region (15.8%) followed by mandibular body and ramus, mandibular third molar, mandibular anterior teeth. Incidence of this disease in mandibule was higher than in maxilla. 4. The lesions not associated with adjacent teeth were (14.0%) and in the lesions associated with adjacent teeth (31.5%) showed root resorption, (50.9%) were without root resorption, (35.1%) showed tooth migration and (50.9%) were without tooth migration. 5. The border types of the lesions were scalloped type in (52.6%), smooth type in (47.4%) and morphological type were unilocular in (50.9%), multilocular in (49.1%). 6. The radiologic cyst type of the lesions were follicular type (42.1%) followed by primordial, unclassified odontogenic, residual, lateral periodontal, median mandibular, globulomaxillary type.

  10. Endocrine tumor of the digestive tract - clinical case study

    International Nuclear Information System (INIS)

    Introduction: Endocrine tumors of the digestive tract (ETDT) are neoplasms which stem from the APUD (amine precursors uptake and decarboxylation) cells. There are neuroendocrine pancreatic and gastroenteral carcinoid tumors which stand for 2% of digestive tract tumors, 0,5% of all human malignant neoplasms. All of them have secretion granulations in the cytoplasm. That is why a number of immune histochemic techniques is used in search for biogenic amines and hormones such as gastrin, CCK, GIP, VIP, motilin, glucagon, GRP, PP, GHRH and the others. In the majority of cases neuroendocrine tumors of the rectum are described as dysfunctional, which means that specific clinical symptoms are not connected with their hormonal overproduction. Material and methods: We describe a case of fifty seven years old male patient admitted to the Department of General and Transplant Surgery for the diagnosis and treatment of the rectal tumor. Per rectum examination revealed hard tumor. The pathologic examination of the biopsy taken from the lesion and CT scanning confirmed the presence of endocrine tumor of the digestive tract. Results: Anterior resection of the rectum was performed, the postoperative course was uneventful. At present patient is subjected to complementary treatment with the use of somatostatin analogue of the prolonged action. Conclusion: The endocrine tumors of the rectum are extremely rare, they occur in this localization in 0,26-0,52 out of 100.000 all rectal tumors. Diagnosis is usually made upon the microscopic examination and the immune histochemic reactions. (author)

    Superparamagnetic iron oxide (AMI 25) is a promising new contrast agent for imaging the reticuloendothelial-system. Iron oxide crystals possess a large magnetic susceptibility and enhance proton relaxation rates, especially transverse relaxation (T2). In order to guide the clinical utilization of this contrast media 4 patients with malignant lesions of the liver are analyzed before and after slow intravenous administration (20 {mu}mol Fe/kg) of AMI 25. Two magnetic resonance (MR) sequences are performed at different times using 0.35 T magnet. MR signal-to-noise ratio (SNR) of the reticuloendothelial-system (particularly the liver SNR) decrease promptly. The maximum decrease in SNR (67-72 percent for the liver, 46-65 percent for the spleen, 23-41 percent for the bone marrow) is observed 3 h after injection (P<0.01). However, except the peak of contrast enhancement in T1-weighted sequence of splenic tissue, the curve describes a plateau within 30 min and 6 h, allowing a delay between injection and imaging. T2-weighted sequences give a greater contrast-to-noise ratio (CNR) by adding the spontaneous tumor contrast to the effect yielded by AMI 25. These results suggest that images must be acquired between 1 and 6 h after intravenous administration of superparamagnetic iron oxide. (author). 18 refs.; 6 figs.

  12. Retromolar foramen: an anatomical study with clinical considerations.

    Gamieldien, M Y; Van Schoor, A

    2016-09-01

    The retromolar canal and foramen, an anatomical variation in the mandibular retromolar area, houses and transmits neurovascular elements that may innervate the mandibular third molar and associated tissues. These structures have been implicated in local anaesthetic failure, loss of sensation in the normal distribution of the buccal nerve, and local haemorrhage during surgery. Examination of 885 dry mandibles showed that 70 had a retromolar foramen (8%). There were no significant differences between groups according to age, sex, or ancestry. The mean (SD) distance from molar to retromolar foramen was 16.8 (5.6) mm for the mandibular second molar and 10.5 (3.8) mm for the mandibular third molar. The link between these structures and failure of local anaesthesia seems tenuous at best. Bleeding may not represent a serious complication. Although there may be a possibility of perineural spread of infective and invasive pathology, we know of no reported cases. The only clear evidence of complications associated with a confirmed retromolar foramen seems to be loss of sensation in the normal distribution of the buccal nerve. Even though the retromolar foramen does not seem to be of great clinical importance, it could be a source of anxiety for the inexperienced practitioner. PMID:27354332

    Radioisotopic splenoportography was performed in 55 patients with portal hypertension, in whom 52 had various degrees of esophagogastric varices, and in 20 patients without portal hypertension. In the patients with varices, collateral images were obtained in 50 patients (96%) by this method and no image was obtained in the patients without varices. The rate of positively imaged collaterals was as follows: Esophageal varices 69%, the left gastric vein 85%, the short gastric veins 48%, RI stasis in esophagogastric region 65%, the azygos vein 46%, the subclavian vein 25%, the para-umbilical veins 46%, splenorenal /gastrorenal shunts 19%, the inferior mesenteric vein 17%, the left intercostal veins 6%, and Arantius's duct 4%. These rates were superior to that obtained from the conventional transarterial portography. There were some correlations between RI-images by this method and clinical and laboratory findings; patients with ascending collaterals alone tended to have extensive and severe varices and higher rate of bleeding, on the other hand, variceal bleeding was not found and episodes of portosystemic encephalopathy frequently occurred in patients with descending collaterals alone. After successful sclerotherapy, RI-images of esophageal varices disappeared in 92% of the patients. Radioisotopic splenoportography appears to be a useful diagnostic and follow-up modality for patients with portal hypertension and esophagogastric varices. PMID:2325608

    Full Text Available Purpose: To clinically describe cases of ocular motor nerve palsy and to determine the possible causes. Materials and Methods: Thirty-one consecutive patients with ocular motor nerve palsies were investigated. All underwent complete ophthalmological, as well as neurological, otorhinolaryngological and general examination. Computerised tomography (CT-scan of the brain and complementary laboratory tests were obtained from each participant. Results: Paralysis of the sixth (38.4% and the third (35.3% cranial nerve were the most common. The Lees screen test was found to be very sensitive, confirming the diagnosis of ocular motor nerve palsy, even in cases with minimal manifestations. Complete ptosis and full mydriasis were mostly seen in isolated cases of the third cranial nerve palsy. The majority of eyes (63.2% with third cranial nerve palsy had pupil sparing. Overall, an etiological diagnosis was made in 93.5% of cases. The common causes were vascular conditions (25.8%, otorhinolaryngologic diseases (19.7% and trauma (12.9%. CT scan failed to reveal any abnormality in 54.8% of cases. Conclusion: Patients with ocular motor nerve palsy should be carefully examined in close collaboration with other specialists, especially where sophisticated, complementary investigations are impossible.

Age of onset of the disease varied from 17 to 85 years, while duration of the disease at the time of presentation varied from 3 days to 13 days. On the basis of clinical features and routine histological findings the cases were divided into various subtypes as : pemphigus foliaceus 65 cases, pemphigus vulgaris 34 patients, pemphigus erythematosus 5, herpetiform pemphigus 3 and vegetans type 2 cases. Three of our patients had diabetes mellitus preceding pemphigus, while 12 patients developed steroid induced diabetes. Significant secondary bacterial infection occurred in all cases at some stage of the disease while oral candidiasis occurred in 15 cases. Eczema herpeticum was seen in 4 patients, while 2 had extensive tinea corporis. One of 4 patients of pemphigus vulgaris had complete shedding of nail and 1 female patient had alternate phases of pemphigus foliaceus and generalized pustular psoriasis. The features in our cases of pemphigus foliaceus were somewhat similar to Brazilian pemphigus foliaceus and we had more cases of pemphigus foliaceus, almost exclusively affecting females.

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

    Clinical decision-support systems (CDSSs) comprise systems as diverse as sophisticated platforms to store and manage clinical data, tools to alert clinicians of problematic situations, or decision-making tools to assist clinicians. Irrespective of the kind of decision-support task CDSSs should be smoothly integrated within the clinical information system, interacting with other components, in particular with the electronic health record (EHR). However, despite decades of developments, most CDSSs lack interoperability features. We deal with the interoperability problem of CDSSs and EHRs by exploiting the dual-model methodology. This methodology distinguishes a reference model and archetypes. A reference model is represented by a stable and small object-oriented model that describes the generic properties of health record information. For their part, archetypes are reusable and domain-specific definitions of clinical concepts in the form of structured and constrained combinations of the entities of the reference model. We rely on archetypes to make the CDSS compatible with EHRs from different institutions. Concretely, we use archetypes for modelling the clinical concepts that the CDSS requires, in conjunction with a series of knowledge-intensive mappings relating the archetypes to the data sources (EHR and/or other archetypes) they depend on. We introduce a comprehensive approach, including a set of tools as well as methodological guidelines, to deal with the interoperability of CDSSs and EHRs based on archetypes. Archetypes are used to build a conceptual layer of the kind of a virtual health record (VHR) over the EHR whose contents need to be integrated and used in the CDSS, associating them with structural and terminology-based semantics. Subsequently, the archetypes are mapped to the EHR by means of an expressive mapping language and specific-purpose tools. We also describe a case study where the tools and methodology have been employed in a CDSS to support

    The clinical characteristics of 303 patients who had episodes of feverish convulsions (FC) were retrospectively reviewed. No preference was seen for either sex (1.3/1). In 75.3% of the cases, the convulsions occurred in children under two. There was some predominance of tonic-clonic crisis and generalized clonic-tonic convulsions (85.5%) with 21.8% of complex partial crisis. In 44.8% of the cases a perinatal history of high risk was noted. A comparative investigation was carried out in a subgroup of 244 children in who FC vs non-febrile convulsions (NFC) were during two years. In 35.2% of the patients neurological abnormalities were found associated, among them were language difficulties (27.4%) and psychomotor retardation (11.9%). In 36.4% of the cases, the EEG was found to be abnormal, and paroxysmal in 27%. The predominating perinatal pathological complications were perinatal hypoxia-anoxia and prematurity. In 84% of the patients, anti-convulsive medication was administered. Of the 244 patients, 62 (25.4) of them had NFC which were directly related to the number of risk factors and their characteristics. Among those risk factors were partial convulsions, neurological deficit, abnormal EEG, convulsions lasting over 10 minutes and a previous family history of epilepsy. It is noteworthy that 15.7% of the patients had no risk factors related to epilepsy. In those patients who suffered from convulsions from an early age, who had convulsions of a partial--complex type, which lasted over 20 minutes and repeated frequently--were seen to be the most likely to develop epilepsy. The medications prescribed prevented the occurrence of the FC but did not significantly diminish the development of epilepsy. Febrile convulsions; epilepsy; perinatal. PMID:1692466

    The rheumatology field is moving towards identifying individuals with an increased risk for rheumatoid arthritis (RA) at a stage when arthritis is still absent but persons having clinically suspect arthralgia (CSA). Incorporating patients' views in rheumatologic care is pivotal; however, the views of persons with CSA on their condition are unknown. We aimed to help fill this gap by exploring illness perceptions of persons with CSA and their views on hypothetical prognoses for developing RA. Persons with CSA were invited to participate in a semi-structured focus group discussion. Illness perceptions according to the Common Sense Model (CSM) and four a priori formulated themes were explored in detail during the group discussion. The discussion was audio-taped and transcribed verbatim. Transcripts were analysed in an interpretative phenomenological approach manner, on the basis of the dimensions of the CSM by three researchers independently. The views of four participants with CSA were explored during one focus group discussion. Four dimensions of the CSM were mainly observed: Identity, Consequences, Personal Control and Concern. None of the patients identified themselves as being a patient. They did experience pain and impairments in daily functioning and were concerned that their symptoms would progress. In the absence of physician-initiated treatment, some patients changed lifestyle in order to reduce pain and to promote health. Patients unanimously said that they could not interpret prognostic information on RA development expressed in hypothetical chances. Persons with CSA do not consider themselves patients. Prognostic information related to the development of RA based on risk percentages was considered as not useful by persons with CSA. Understanding of the illness perceptions of persons with CSA by health care professionals might improve medical management and facilitate shared decision-making. PMID:26272058

    In this paper we discuss the concept of leadership as a personal capability, not contingent on one's position in a hierarchy. This type of leadership allows us to reframe both the care-giving and organizational roles of nurses and other front-line clinical staff. Little research has been done to explore what leadership means at the point of care, particularly in reference to the relationship between health care practitioners and patients and their family caregivers. The Adaptive Leadership framework, based on complexity science theory, provides a useful lens to explore practitioners' leadership behaviors at the point of care. This framework proposes that there are two broad categories of challenges that patients face: technical and adaptive. Whereas technical challenges are addressed with technical solutions that are delivered by practitioners, adaptive challenges require the patient (or family member) to adjust to a new situation and to do the work of adapting, learning, and behavior change. Adaptive leadership is the work that practitioners do to mobilize and support patients to do the adaptive work. The purpose of this paper is to describe this framework and demonstrate its application to nursing research. We demonstrate the framework's utility with five exemplars of nursing research problems that range from the individual to the system levels. The framework has the potential to guide researchers to ask new questions and to gain new insights into how practitioners interact with patients at the point of care to increase the patient's ability to tackle challenging problems and improve their own health care outcomes. It is a potentially powerful framework for developing and testing a new generation of interventions to address complex issues by harnessing and learning about the adaptive capabilities of patients within their life contexts.

  6. The Clinical Study on 39 Cases of Subclinical Hypothyroidism

    International Nuclear Information System (INIS)

    Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain an euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 39 cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean age was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum T3 and T4 concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism (32.61±14.95 μU/ml) was significantly higher than that of normal controls (3.92±1.05 μU/ml) (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter (15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis (3.8%).

    Full Text Available The objective of studies of danger perception is to predict the behavior of a person, group, or society in terms of the potential hazard, to identify the main groups of factors that affect the risk assessment and sources of distortion of the evaluation. The review presents the sociological theories of danger, reveals the gender differences in the danger perception, and describes in details the individual factors of danger perception. We discuss the prospects of studying the outside world danger perception in clinical psychology of development. We emphasize that the key period for the development of danger assessment process is adolescence, because this is the age when most significant quantitative and qualitative changes in the cognitive sphere occur: the development of abstract logical thinking, increased interest to the life and death, the appearance of “personal myth”.

    Full Text Available Abstract Background Many risk factors for fractures have been documented, including low bone-mineral density (BMD and a history of fractures. However, little is known about the short-term absolute risk (AR of fractures and the timing of clinical fractures. Therefore, we assessed the risk and timing of incident clinical fractures, expressed as 5-year AR, in postmenopausal women. Methods In total, 10 general practice centres participated in this population-based prospective study. Five years after a baseline assessment, which included clinical risk factor evaluation and BMD measurement, 759 postmenopausal women aged between 50 and 80 years, were re-examined, including undergoing an evaluation of clinical fractures after menopause. Risk factors for incident fractures at baseline that were significant in univariate analyses were included in a multivariate Cox survival regression analysis. The significant determinants were used to construct algorithms. Results In the total group, 12.5% (95% confidence interval (CI 10.1–14.9 of the women experienced a new clinical fracture. A previous clinical fracture after menopause and a low BMD (T-score Conclusion In postmenopausal women, clinical fractures cluster in time. One in two women with a recent clinical fracture had a new clinical fracture within 5 years, regardless of BMD. The 5-year AR for a first clinical fracture was much lower and depended on BMD.

    Full Text Available Electrochemotherapy is becoming a well-established treatment for malignancies of skin and non-skin origin and its use is widening across Europe. The technique was developed and optimized from solid experimental and clinical evidence. A consensus document is now warranted to formalize reporting results, which should strengthen evidence-based practice recommendations. This consensus should be derived from high quality clinical data collection, clinical expertise and summarizing patient feedback. The first step, which is addressed in this paper, aims to critically analyze the quality of published studies and to provide the recommendations for reporting clinical trials on electrochemotherapy.

    Full Text Available Background: The sixth cranial nerve has been found to be the most commonly affected in previous studies of cranial nerve palsies. This study was carried out to determine the most common nerve involved in extraocular muscle (EOM palsies and the most common cause of EOM palsy in Nepal.Methods: The diagnosed cases of third, fourth, or sixth nerve palsy for 10 years (2000-2010 at the B.P. Koirala Lions Center for Ophthalmic Studies outpatient department were included in the study. A retrospective review of patients’ records was performed, and the causes of EOM palsy were grouped as: vascular, trauma, tumor,aneurysm, undetermined, and others. Recovery of the palsy was evaluated by reviewing the records of the patients who were followed up one month after the initial visit.Results: A total of 838 patients was included in the study. The average patient age was 37 years. The sixth nerve was most commonly affected (n=458, 54.65%, and the most common etiology was undetermined (n=408, 48.68%. Among the cases where the cause of palsy was known, the largest number of patients had trauma (n=188, 16.46%.Conclusion: It was concluded that in Nepal, the most commonly affected cranial nerve is the sixth nerve, in accordance with the other studies done in the past in different parts of the world. Most of the cases of cranial nerve palsy were found to have no specific cause and were not associated with diagnosed systemic disease.

    Full Text Available Clinical training in nursing is fundamental because it transforms the theoretical knowledge of student nurses into clinical skills and practice. In addition, clinical training promotes the development of students’ critical thinking, psychomotor skills as well as patterns of professional contact for patients care.Aim of this qualitative study was to explore student nurses’ views of their clinical training.Material and method: Focus groups of 40 student nurses were held to explore their views on their clinical training and studying in a nursing school of a Technological Educational Institute. The participants were divided into four groups of ten students in order to facilitate the focus group interviews. The qualitative data derived from the interviews, was analyzed using thematic categories and coding.Results: From data analysis of the focus group interviews, five thematic categories emerged. In accordance with student nurses’ views in this study “stress and clinical learning environment” “theory practice gap”, “the role of lecturer practitioner - assessor”, “the lack of opportunities for critical thinking development”, “the search of professional patterns from staff and lectures”, were identified as the thematic categories.Conclusions: The results of the study indicated that student nurses were not particularly satisfied with the quality of their clinical training. In addition, it is apparent that the necessity to foster the role of lecturer practitioners, which they need specialized education on providing clinical training to student nurses, aiming to establish professional patterns to them.

  20. Radioactive Aerosols in the Clinical Study of Pulmonary Clearance

    International Nuclear Information System (INIS)

    The study of pulmonary clearance mechanisms has acquired particular importance owing to the growing pollution of the environment and to the increasing incidence and seriousness of cases of pneumoconiosis. Such research is particularly important in radiopathology because of the frequent occurrence of respiratory radioactive contamination. The authors' aim is to tackle this problem and in particular to study long-term clearance mechanisms. Before starting this work, however, they propose to determine the contamination parameters as accurately as possible. For this purpose they plan to study respiratory function in normal subjects by administering labelled aerosols with well-defined physico-chemical characteristics; the first stage of the investigation is then to observe the kinetics of fixation and clearance in the short term. They describe the installations used for this voluntary contamination which must provide a means of producing the aerosols and administering them in controlled amounts and must also ensure efficient protection of the operators against irradiation arid contamination. The choice of the aerosols is also discussed: this is governed mainly by the nature of the vectors, the particle size and the physical characteristics of the tracers. Finally, the authors outline the detection and measuring techniques which they are using to study contamination kinetics, evaluate contamination burdens and follow the short-term clearance. These data constitute a preliminary basis for the study of long-term clearance. (author)

    Medical imaging is a long established part of patient management in the treatment of disease. However, in most cases it only provides anatomical detail and does not provide any form of tissue characterisation. This is particularly true for X-ray imaging. Recent studies on tissue diffraction have shown that true molecular signatures can be derived for different tissue types. Breast cancer samples and liver tissue have been studied. It has been shown that diffraction profiles can be traced away from the primary tumour in excised breast tissue samples and that potentially 3mm fat nodules in liver tissue can be identified in patients at acceptable doses.

    Hypnotherapy's effectiveness in improving and controlling chronic pain of various etiologies has been demonstrated by studies; the mechanism by which hypnosis does this is more complex than a simple induction of muscle relaxation. This study reveals, in addition to this mechanism, a deeper dimension of hypnotherapy from the vantage of a patient with a medical-surgical background, diagnosed with a pain disorder and major severe depressive disorder in addition to incurable painful symptoms, through treatment associated with hypnoanalysis. Following psychotherapy, which included some elements of cognitive-behavioral therapy, a complete remission of the anxious-depressive mood and the painful symptoms was achieved. PMID:25719524

    Full Text Available BACKGROUND More than a century after its comprehensive description, acute pancreatitis remains a common disorder with devastating consequences. The presentation of wide spectrum of symptoms gives the clinician a heart breaking exercise to bring back the patient from the clutches of the disease process. Pancreatitis by itself is a disease which is unique, protean and extrudes into the diagnostic arena. It cannot be too strongly emphasized that the primary treatment of acute pancreatitis is conservative only, but it is the Pandora’s box of manifestation with its inherent complications from surgery comes into play as diagnostic, prognostic and therapeutic endeavour. To study age and sex incidence of acute pancreatitis, to study and analyse the etiopathological factors associated with acute pancreatitis, especially alcohol aetiology in our study. To analyse the prognosis of acute pancreatitis using CT scan abdomen. To analyse the complications, to analyse the role of surgery in acute pancreatitis. METHODS This study was carried out on patients admitted in the General Surgery Department, MGM Hospital, from December 2013 to June 2015. RESULTS The incidence of acute pancreatitis was found to be in a younger age group in our study. Serum amylase and lipase both (80% sensitivity should be used for diagnosis wherever possible. Ideally, all cases should be stratified during the first 48 hours according to one of the scoring systems (Balthazar’s. Scoring systems help to identify patients who are more likely to have a severe attack and they should be referred to higher centres if adequate facilities are not available.

    A conflict of interest is defined as "a set of conditions in which professional judgment concerning a primary interest (such as a patient's welfare or the validity of research) tends to be unduly influenced by a secondary interest (such as financial gain)" [Thompson DF. Understanding financial conflicts of interest. N Engl J Med 1993;329(8):573-576]. Because financial conflict of interest (fCOI) can occur at different stages of a study, and because it can be difficult for investigators to detect their own bias, particularly retrospectively, we sought to provide funders, journal editors and other stakeholders with a standardized tool that initiates detailed reporting of different aspects of fCOI when the study begins and continues that reporting throughout the study process to publication. We developed a checklist using a 3-phase process of pre-meeting item generation, a stakeholder meeting and post-meeting consolidation. External experts (n = 18), research team members (n = 12) and research staff members (n = 4) rated or reviewed items for some or all of the 7 major iterations. The resulting Financial Conflicts of Interest Checklist 2010 consists of 4 sections covering administrative, study, personal financial, and authorship information, which are divided into 6 modules and contain a total of 15 items and their related sub-items; it also includes a glossary of terms. The modules are designed to be completed by all investigators at different points over the course of the study, and updated information can be appended to the checklist when it is submitted to stakeholder groups for review. We invite comments and suggestions for improvement at http://www.openmedicine.ca/fcoichecklist and ask stakeholder groups to endorse the use of the checklist. PMID:21686297

    Full Text Available PURPOSE: To estimate the prevalence of fundus changes in Pregnancy Induced Hypertension (PIH and to find the correlation of the findings with the levels of hypertension and with the severity of the disease. METHODS: This was a hospital based cross section al study conducted over a period of one year from July 2012 to June 2013. 150 patients with diagnosed PIH and admission into wards at King George Hospital, Visakhapatnam, with 36 weeks period of gestation and above, were included in the study. Those with p re - existing hypertension, coexisting diabetes mellitus, severe anaemia, renal disease and ocular diseases like cataract or corneal opacities were excluded from the study. After taking consent and ocular history, anterior segment was evaluated. Pupils were dilated with 0.5% tropicamide eye drops and fundus examination was done with direct ophthalmoscope. Information like age, para, BP etc., was noted down from case sheets. RESULTS: Total number of patients studied was 150.Mean age was 23.06+ 3.03years. 105 ( 70% were primigravidae and 45(30% were multigravidae. Fundus findings were seen in 35 cases (23.33%. 26 (17.33% had Grade I changes, 1 (0.66% had grade II changes, 6 (3.9% had grade III changes 2 (1.3% had serous retinal detachment/grade - IV. The de gree of retinopathy was correlating with the severity of the disease and levels of hypertension. CONCLUSION: The prevalence of fundus changes in PIH is 23.33%. Most of the fundus changes in PIH are underdiagnosed. Timely ophthalmoscopy should be called for in all cases of PIH as it would affect the decision of induction of delivery, thereby preventing other complications.

    2012-01-01

    Full Text Available Objectives: To study the ongoing inflammatory process of lung in healthy individuals with risk factors and comparing with that of a known diseased condition. To study the inflammatory response to treatment. Background: Morbidity and mortality of respiratory diseases are raising in trend due to increased smokers, urbanization and air pollution, the diagnosis of these conditions during early stage and management can improve patient′s lifestyle and morbidity. Materials and Methods: One hundred subjects were studied from July 2010 to September 2010; the level of hydrogen peroxide concentration in exhaled breath condensate was measured using Ecocheck. Results: Of the 100 subjects studied, 23 were healthy individuals with risk factors (smoking, exposure to air pollution, and urbanization; the values of hydrogen peroxide in smokers were 200-2220 nmol/l and in non-smokers 340-760 nmol/l. In people residing in rural areas values were 20-140 nmol/l in non-smokers and 180 nmol/l in smokers. In chronic obstructive pulmonary disease cases, during acute exacerbations values were 540-3040 nmol/l and 240-480 nmol/l following treatment. In acute exacerbations of bronchial asthma, values were 400-1140 nmol/l and 100-320 nmol/l following treatment. In cases of bronchiectasis, values were 300-340 nmol/l and 200-280 nmol/l following treatment. In diagnosed pneumonia cases values were 1060-11800 nmol/l and 540-700 nmol/l following treatment. In interstitial lung diseases, values ranged from 220-720 nmol/l and 210-510 nmol/l following treatment. Conclusion: Exhaled breath condensate provides a non-invasive means of sampling the lower respiratory tract. Collection of exhaled breath condensate might be useful to detect the oxidative destruction of the lung as well as early inflammation of the airways in a healthy individual with risk factors and comparing the inflammatory response to treatment.

  6. The Power of Phase I Studies to Detect Clinical Relevant QTc Prolongation: A Resampling Simulation Study

    Directory of Open Access Journals (Sweden)

    Georg Ferber

    2015-01-01

    Full Text Available Concentration-effect (CE models applied to early clinical QT data from healthy subjects are described in the latest E14 Q&A document as promising analysis to characterise QTc prolongation. The challenges faced if one attempts to replace a TQT study by thorough ECG assessments in Phase I based on CE models are the assurance to obtain sufficient power and the establishment of a substitute for the positive control to show assay sensitivity providing protection against false negatives. To demonstrate that CE models in small studies can reliably predict the absence of an effect on QTc, we investigated the role of some key design features in the power of the analysis. Specifically, the form of the CE model, inclusion of subjects on placebo, and sparse sampling on the performance and power of this analysis were investigated. In this study, the simulations conducted by subsampling subjects from 3 different TQT studies showed that CE model with a treatment effect can be used to exclude small QTc effects. The number of placebo subjects was also shown to increase the power to detect an inactive drug preventing false positives while an effect can be underestimated if time points around tmax are missed.

    1991-12-31

    The urinary trypsin inhibitor (UTI) is an acid stable proteinase inhibitor present in blood and urine. It was purified from urine using affinity chromatography, ion exchange chromatography and gel filtration. Two forms of UTI were present in urine, A and B. A radioimmunoassay for measurement of UTI in urine and plasma was performed. The normal level of UTI in plasma and serum was about 2 mg/l. The normal excretion in urine was about 8 mg per 24 hours. The plasma and urine levels of UTI were studied in patients with acute pancreatitis and in patients undergoing cholecystectomy. Uremic patients had a marked increase of UTI in plasma compatible with decreased glomerular filtration. In samples from healthy persons as well as from patients only inhibitor A was found. Inhibitor B has recently been renamed bikunin because of its two Kunitz-type inhibiting domains. Inhibitor A might be called tetrakunin. Radioactively labeled UTI (inhibitor A) was injected intravenously in three male volunteers. The plasma half-life of {sup 125}I UTI was 2 hours. Free biologically active inhibitor was found in the urine during the first four hours after injection. The organ distribution of intravenously injected {sup 125}I UTI was studied in rats. Fifteen minutes after injection the major part of the radioactivity was found in the kidneys, suggesting that the kidneys are the primary site of UTI metabolism. Using immunohistochemical techniques UTI was found in the proximal tubules of the normal human kidney further indicating the tubular reabsorption and methabolisms of UTI.

  13. Study of a Scintillation Camera: Description and Clinical Application

    International Nuclear Information System (INIS)

    The spatial distribution of radioactivity within an organ is at present studied routinely with the aid of mobile detectors capable of examining different points in the organ one after the other by means of scanning. In recent years efforts have been made to construct fixed detectors which are able to explore all the points within an organ simultaneously. A detector of this sort is now being used by the authors of the paper. The paper explains the functioning of the apparatus in which a single crystal is viewed by a number of photomultipliers. The main components of the apparatus are as follows: (a) A detector head consisting of a crystal and 7 photomultipliers, plus a conical chamber fitted with a diaphragm or a grid; (b) Devices for localizing scintillations in the crystal and for pulse selection, and (c) Recording equipment consisting of two cathode-ray oscilloscopes fitted with a camera; one of these is equipped with a remanence memory tube. The paper then describes the operating technique: approaching the organ; studying recording times; using the screen of the memory oscilloscope; producing the photograph. Finally, the authors discuss the results obtained in exploring various organs, give some general information on the technique and adumbrate a number of novel applications. (author)

    International Nuclear Information System (INIS)

    Eighty patients have been treated with Pi-mesons (pions) at TRIUMF between 1979-1984. The patients had tumors rarely curable by standard methods and had no prior radiotherapy. The distribution by site included skin, metastatic nodules (13), brain, glioblastoma multiforme (32), pelvis, rectosigmoid (15), prostate (12), bladder (7), and ovary (1). The studies involve serial escalations of pion dose until maximum tissue tolerance is reached, monitoring the response at each dose increment. Sites were chosen for study where lack of local control is a significant cause of treatment failure with conventional radiation therapy. The low dose rate and the available beam access at TRIUMF limit the number of patients treated and the volume treatable. A 3-D treatment planning program is in use, and a 3-D display of the dose distribution delivered in brain tumor treatments has been developed using the PET scanner. In practice, new methods introduced for measurement of tissue response include tumor growth delay curves, fine-needle biopsy mapping, and PET scanning of brain tumors. The use of endoscopic assessment of the rectosigmoid region is emphasized. Treatment results of glioblastoma multiforme show that the median survival for patients treated to 125 pion cGy/fx is in the range of 187-198 days; for patients receiving 170 cGy per dose/fraction (fx) the range is 290-315 days, and for those receiving 200-220 cGy/fx the median survival is in excess of 290 days. For pelvic malignancies the local control obtained with doses of 2500 cGy or less was 50% in 12 asable patients; it was 75% in 20 patients who had 3000 cGy or more

  17. Functional MRI in human motor control studies and clinical applications

    International Nuclear Information System (INIS)

    Functional magnetic resonance imaging (fMRI) has been a useful tool for the noninvasive mapping of brain function associated with various motor and cognitive tasks. Because fMRI is based on the blood oxygenation level dependent (BOLD) effect, it does not directly record neural activity. With the fMRI technique, distinguishing BOLD signals creased by cortical projection neurons from those created by intracortical neurons appears to be difficult. Two major experimental designs are used in fMRI studies: block designs and event-related designs. Block-designed fMRI presupposes the steady state of regional cerebral blood flow and has been applied to examinations of brain activation caused by tasks requiring sustained or repetitive movements. By contrast, the more recently developed event-related fMRI with time resolution of a few seconds allows the mapping of brain activation associated with a single movement according to the transient aspects of the hemodynamic response. Increasing evidence suggests that multiple motor areas are engaged in a networked manner to execute various motor acts. In order to understand functional brain maps, it is important that one understands sequential and parallel organizations of anatomical connections between multiple motor areas. In fMRI studies of complex motor tasks, elementary parameters such as movement length, force, velocity, acceleration and frequency should be controlled, because inconsistency in those parameters may alter the extent and intensity of motor cortical activation, confounding interpretation of the findings obtained. In addition to initiation of movements, termination of movements plays an important role in the successful achievement of complex movements. Brain areas exclusively related to the termination of movements have been, for the first time, uncovered with an event-related fMRI technique. We propose the application of fMRI to the elucidation of the pathophysiology of movement disorders, particularly dystonia

    This qualitative study explored the clinical nursing leadership competency perspectives of Thai nurses working in a university hospital. To collect data, in-depth interviews were undertaken with 23 nurse administrators, and focus groups were used with 31 registered nurses. Data were analyzed using content analysis, and theory development was guided by the Iceberg model. Nurses' clinical leadership competencies emerged, comprising hidden characteristics and surface characteristics. The hidden characteristics composed three elements: motive (respect from the nursing and healthcare team and being secure in life), self-concept (representing positive attitudes and values), and traits (personal qualities necessary for leadership). The surface characteristics comprised specific knowledge of nurse leaders about clinical leadership, management and nursing informatics, and clinical skills, such as coordination, effective communication, problem solving, and clinical decision-making. The study findings help nursing to gain greater knowledge of the essence of clinical nursing leadership competencies, a matter critical for theory development in leadership. This study's results later led to the instigation of a training program for registered nurse leaders at the study site, and the formation of a preliminary clinical nursing leadership competency model.

  1. Molecular biology of breast cancer metastasis: Clinical implications of experimental studies on metastatic inefficiency

    International Nuclear Information System (INIS)

    Recent technological advances have led to an increasing ability to detect isolated tumour cells and groups of tumour cells in patients' blood, lymph nodes or bone marrow. However, the clinical significance of these cells is unclear. Should they be considered as evidence of metastasis, necessitating aggressive treatment, or are they in some cases unrelated to clinical outcome? Quantitative experimental studies on the basic biology of metastatic inefficiency are providing clues that may help in understanding the significance of these cells. This understanding will be of use in guiding clinical studies to assess the significance of isolated tumour cells and micrometastases in cancer patients

    Diffuse reflectance spectroscopy is a technique widely used to determine optical properties of tissues: scattering and absorption coefficients. In this study, we present the development of a low-cost optical instrument usable in a clinical environment based upon the spatially resolved diffuse reflectance spectroscopy approach. This instrument has been used in a clinical study to support the diagnosis of tuberculosis. The idea is to establish a new scanning method for an early detection of inflammation due to a reagent injection, before the onset of visual signs. Results comparing the instrumental and classical clinical readings are presented.

  4. A clinical study of navigation accuracy during surgery

    International Nuclear Information System (INIS)

    It is essential to implement image-guided surgery or neuronavigation technologies that can be applied during functional surgery to localize targets accurately in the surgical field. Various navigation systems have been developed, such as the optical system and mechanical-arm-based system, to localize targets in the operative field. However, either the reference system, in optical systems, or the arm joint, in mechanical-arm-based systems, can sometimes interfere with surgical maneuvers. Therefore, we used the magnetic-force-based Computed Assisted Neurosurgery system (CANS system, Shimadzu, Co. Ltd., Kyoto, Japan) for neuronavigation. The purpose of this study was to evaluate the accuracy of the CANS navigation system. Ten patients with medically refractory epilepsy underwent implantation of subdural electrode grids to detect the epilepsy focus, and then lobectomy or multiple subpial transection was performed after informed consent was obtained. The male/female ratio was 6:4 and the mean age was 30.7 years. The CANS navigator system consists mainly of a magnetic source, a localizer probe with magnetic sensor, a three-dimensional locating measuring instrument (digitizer), an image scanner, and a personal computer. To determine the localization accuracy, the probe was moved on the subdural electrode grid which typically consists of 64 or 16 platinum-iridium electrode contacts (3 mm in the diameter) embedded in a Silastic sheet. The array of electrodes was 8 x 8 cm or 2 x 8 cm and the center-to-center inter-electrode distance was 10 mm. We evaluated the inter-electrode distances and spatial relationships among the electrodes to quantitate the precision of the probe tip localization and assumed the nasion origin reference system to assess the distribution of target coordinates. The measurement errors of each component derived from different planes for the same targets were evaluated in ten patients. The error in X-dimension ranged from 0.38 mm to 7.8 mm, the error in Y

  17. Clinical study of T3/T4 laryngeal carcinoma

    International Nuclear Information System (INIS)

    A total of 72 consecutive laryngeal carcinoma patients at stage T3 or T4 were studied. The laryngeal cancer patients were treated first with concurrent chemoradiotherapy (40 Gy) in our department. Patients with residual disease subsequently underwent curative surgery, and chemoradiotherapy was continued to 70 Gy for those without residual disease. The three-year disease-specific-free survival (DSS) rates in patients with supraglottic, glottic and subglottic tumors were 58%, 71% and 100%, respectively. In patients at stage T3/T4, the DSS rates were 75%/46%, and in those with/without lymph node metastasis (N+/N-) the rates were 56%/78%. The three-year laryngeal preservation (LP) rates in patients with supraglottic/glottic/subglottic tumors, T3/T4 and N+/N- tumors were 12%/26%/50%, 28%/4% and 13%/29%, respectively. The recurrence rate was 29%, of which 75% have died, primarily of distant metastasis. These DSS and LP rates were not significantly different among the three subregions and N stages, although those in patients at stage T4 were significantly low, compared with T3 patients (p=0.01). These results suggest that additional treatment may be required for patients with T4 disease. Chemotherapy after surgery is now considered for T4 patients. (author)

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Uterine papillary serous carcinoma (UPSC) was established as a distinct type of endometrial carcinoma by Lauchlan in 1981 and Hendrickson et al in 1982, and accounted for 1% ~ 10% of endometrial cancers. Theoccurencer of papillary patterns of endometrial adenocarcincma had been reportedly recognized since 1900, while until the late 1970s several authors have had described a variant of papillary endometrial cancer. UPSC is a morphologically unique variant of endometrial carcinoma that is pathologically defined by the presence of high nuclear grade, distinct papillary architechtural changes, psammoma bodies, and extensive lymph- vascular space invasion. CA125 is often mentioned a usefultumor marker either for diagnosis before starting treatment or in monitoring recurrence. The ptimal treatment of UPSC is controversial and appears to be dependent upon the stage of the disease. Primary surgery comprised of TAH/BSO and complete staging is the mainstay of treatment. The patients with recurrent UPSC in many studies were treated with various combinations of surgery, radiation therapy, and chemotherapy. The molecular basis for the general poor response of UPSC to adjuvant chemotherapy and radiotherapy is not well understood. UPSC tumors are more often aneuploid and contain overexpressed mutant p53 protein as compared to encdometrioid adenocarcinoma. Unlike patients with adenocarcinoma of the endomeutrium, women with UPSC were less likely to be obese, hypertensive, or diabetic.

    Full Text Available Micro laryngeal surgery is a common and relatively safe ENT surgery, certain laryngeal conditions require surgery for correction. Surgery for voice problems is quite uncommon, most of the voice disorders can be treated with voice therapy or medical treatment. However there are certain conditions may required operative measures. We have been doing micro laryngeal surgery(MLS in our institute for quite a long time, but use of powered instruments like, microdebrider technique in MLS have been increased in recent days. We are here discussing the advantages of powered instrumentation in MLS and merits and demerits over the conventional instruments, a comparative study in 40 cases was carried out in our institute. Endoscopic debulking of obstructive laryngeal tumors to obtain an adequate airway is traditionally done with cold steel instruments or carbon dioxide lasers, however that technological advances and an increase in the availability of microdebrider have made powered instrumentation a good alternative to cold steel and lasers in this application. XPS microdebrider technique is a safe, effective, and rapid method for debulking obstructive laryngeal tumors and other laryngeal lesions.

  20. Clinical study concerning upper urinary tract obstruction, 2

    International Nuclear Information System (INIS)

    To establish a method of detecting divided renal function of the obstructed kidneys non-invasively, comparative studies on sup(99m)Tc-DMSA uptake (60 minutes after injection), I 131-hippuran renal uptake (1-2 minutes after injection) and divided creatinine clearance immediately after relief of urinary obstruction were made on 24 cases of obstructive uropathy. A close significant correlation was obtained between sup(99m)Tc-DMSA and I131-hippuran renal uptakes γ=0.8809, P<0.001). Also, a significant correlation was noted between sup(99m)Tc-DMSA renal uptake and divided creatinine clearance γ=0.7876, P<0.001), but the latter constantly gave lower values than the former. These observations led us to conclude that sup(99m)Tc-DMSA renal uptake is a reliable indicator of the renal plasma flow in the obstructed kidneys. Quantitative divided renal function of the obstructed kidneys can be estimated by the sup(99m)Tc-DMSA uptake method. (author)
